Description

This disclosure relates to a cooking device that uses multiple heating ports to heat an object to be heated, such as a pot.

Cooking appliances are broadly divided into three types based on the environment in which they are used.
One type is the so-called "built-in type," which is installed inside kitchen furniture such as a kitchen counter. The second type is the "freestanding type," which is placed in a designated location on kitchen furniture like a gas stove (also called a "gas-burning table"). The third type is the small, portable "tabletop type," which is placed in any location on a dining table or similar.

Many "built-in" cooking appliances come with multiple heat sources and are popular for their ability to handle a variety of cooking methods. However, because they are installed inside kitchen furniture, the external dimensions must be designed to conform to standard kitchen furniture standards, meaning there is significantly less design freedom compared to "freestanding" or "tabletop" appliances, making it difficult to create a practical product.

A typical built-in cooking appliance has multiple heating ports located on the top of the main body, which perform induction heating, and a grill chamber (also called an "oven chamber" or "heating chamber," but hereafter referred to collectively as the "heating chamber") inside the main body, in which microwaves from a microwave heating source are introduced to cook food (see, for example, Patent Document 1). There are also cooking appliances that use radiant heat from an electric heater (grill heater) in the heating chamber (see, for example, Patent Documents 2 and 3). Appliances like these, which have multiple heating sources with different heating principles, are called combined cooking appliances.

JP 2022-117570 A (Page 1, FIG. 29) Japanese Patent No. 5661109 (page 1, Figure 4) JP 2011-252699 A (page 1, FIG. 6)

As proposed in the above-mentioned Patent Documents 1 and 2, in the case of a combined heating cooker, the number of heating means and input operation units increases, and the work of the user individually setting one cooking condition becomes more complicated. In particular, when there are multiple heating ports, a display unit is provided for each heating port, and the user is required to input heating conditions such as heat power and the desired cooking mode, cooking menu, etc. while looking at the display unit, which inevitably increases the number of confirmations and input operations required by the user and makes the operation more complicated.
Therefore, as shown in Patent Document 3, it has been proposed to provide a single display unit (such as a liquid crystal display screen) and to use that single display screen to centrally select multiple heating ports or heating means, or input control conditions, etc.
However, when one display unit (such as a liquid crystal display screen) is used in common for different heating ports or heating means, it is necessary to devise a display content that does not cause misunderstanding or visual confusion for the user regarding the correspondence between the intended heating port or heating means. However, the above-mentioned Patent Document 3 does not yet provide sufficient measures to address this issue.

The objective of this disclosure is to provide a highly convenient cooking appliance that can perform various cooking methods using multiple heating ports by improving user operability.

The cooking device according to the present disclosure will be described below with reference to the drawings. In the following description, terms indicating directions (e.g., "up," "down," "right," "left," "front," "rear," etc.) are used to facilitate understanding, but these are for explanatory purposes only. In addition, in each drawing, items with the same reference numerals are the same or equivalent items, and this applies throughout the entire specification.

Furthermore, in the following description, a composite cooking device equipped with a plurality of types of heating means will also be simply referred to as a "cooking device."
In the following description, the phrase "a heated object placed on the top plate" refers to both a case where a heated object such as a pot is placed directly on the upper surface of the top plate 3 (described later) and heated (by the first heating means HM1), and a case where a heated object is placed on a support member such as a trivet arranged above the top plate, as in a gas burner, and heated. In other words, the first heating means HM1 is not limited to induction heating means.

In the first embodiment, the "second heating means" HM2 refers to a heat source for heating food contained in the heating chamber 6, which will be described later. It may also be one that uses radiant heat or steam.
In the first embodiment, a microwave heating source is provided as the second heating means HM2. The microwave heating source uses a magnetron, but there is no limitation on the microwave oscillation principle or method, and it may be a microwave oscillator using a semiconductor element, etc. Furthermore, a plurality of heating sources may be provided.

In this embodiment 1, the term "third heating means" HM3 is used to indicate the difference between the first heating means HM1 and the second heating means HM2, but does not imply a superiority or inferiority relationship.
In addition, in embodiment 1, a heat source using a radiant electric heat source (sheath heater, mica heater, carbon heater, ceramic heater, infrared heater, radiant heater, etc.) is used, but a heat source that generates heat in other forms or methods may also be used.

The third heating means HM3 is capable of cooking in a single heating chamber 6. It may be a combination of multiple heating sources with different heating principles, such as a heating source consisting of an electric heater and a gas combustor (burner). An induction heating source may also be used as the heating source for heating the heating chamber 6. It may also be a steam generator (boiler) (not shown) that supplies high-temperature steam (such as superheated steam).

Furthermore, the third heating means HM3 may be either a heat source that heats the wall surface of the heating chamber 6 from the outside, or a heat source that is installed in the internal space of the heating chamber 6 and heats the atmosphere in the internal space to a high temperature.
Alternatively, a heat-generating member that becomes hot by induction heating may be placed in the heating chamber, and this heat-generating member may heat the wall surface of the heating chamber 6 from the outside. Furthermore, a heat source may be provided outside the heating chamber 6, and high-temperature air may be supplied into the heating chamber 6.

A typical example of the induction heating coil (IH coil) referred to in this embodiment 1 is one made by bundling approximately 30 thin copper or aluminum wires of approximately 0.1 mm to 0.3 mm, twisting several of these bundles together, and winding them into a spiral. Alternatively, there is also one made by winding approximately 1,000 to 1,500 wires of approximately 0.05 mm. There is also a proposal to use a ring-shaped conductor made of a flat conductive material. All of these configurations correspond to the "IH coil" that is the main part of the first heating means HM1 (induction heating source).

In the following description, the term "cooking mode" refers to a classification of cooking modes broadly categorized based on the number of heating means, and in this embodiment, there are three cooking modes.
That is, there are three types of cooking modes: a cooperative cooking mode KM1, a composite cooking mode KM2, and a single cooking mode KM3 (to be described later) (these three are collectively referred to as "main cooking modes").

In the following description, the term "sub-cooking mode" refers to a sub-category of the cooperative cooking mode KM1, the composite cooking mode KM2, or the single cooking mode KM3, and is a name categorized by the control mode for actually driving the first to third heating means HM1 to HM3. For example, "heat" and "keep warm" in the single cooking mode KM3 (which uses only induction heating or microwave heating) are types of sub-cooking modes. Details will be described with reference to FIGS. 17 and 25.
In the following description, unless otherwise confused, the "cooking mode" includes both the main cooking mode and the sub-cooking mode.

In the following explanation, "coordinated cooking" refers to cooking using two or more heat sources that heat a single item (including food, meat, vegetables, etc.) in different locations and whose heating conditions can be set independently. This cooking mode is referred to as "coordinated cooking mode" KM1.

The above-mentioned "coordinated cooking" refers to the use of multiple heating methods with a time lag. For example, in the process of completing a single cooking step, the food is preheated using a microwave heating source, then moved to another location, where it is heated using an induction coil to complete the cooking process. This is a type of "coordinated cooking" as defined here.

Another type of "cooperative cooking" is to heat the food inside the heating chamber 6 using a gas burner, then move the food onto the top plate 3 and heat it again using the gas burner or induction heating source to improve the cooking quality.

"Voice input mode" refers to a control mode in which the user inputs by speaking, without touching or pressing the buttons or operation surfaces of the input switches (input keys).
In the following explanation, there are two types of "voice input mode": "voice input mode 1", in which voice is input directly into the cooking appliance 1, and "voice input mode 2", in which voice signals are input via an external information processing device such as an external server through an external input device such as a smart speaker.

In the following description, "setting information" refers to information that is given to the cooking appliance 1 to set the control contents (of the heating means) according to recipe data CD, which will be described later.
As will be described later, the cooperative cooking mode KM1 has at least cooking process 1 and cooking process 2. For convenience of explanation, the setting information for cooking process 1 may be referred to as “setting information A,” and the setting information for cooking process 2 may be referred to as “setting information B.”

In the following description, "recipe data" CD refers to data used in controlling the cooker 1 to heat and cook one food item.
One form of recipe data CD is an instruction that includes all of the data specifying the heating means, the data specifying the heating process and order, and the control conditions during heating (including, but not limited to, heat power, target temperature, heating and cooking time, etc.), and also a computer program for realizing the instruction.

Another form of the recipe data CD does not include data specifying the heating means or data specifying the heating steps or order, but includes only some of the data required to execute a cooking menu (e.g., hamburger steak).
For example, when cooking using the collaborative cooking mode KM1 described below, this does not include information specific to the heating means that executes one cooking menu (including information indicating the attributes of the heating means and information about the heating port, etc.), information about the cooking process, information indicating the order in which the heating means are driven, etc.
In this case, the data mainly consists of instructions and data (hereinafter referred to as "commands" or "command data") that determine control conditions such as heating capacity, heating time, etc. In this case, if the recipe data CD held in the cooking appliance 1 is configured on the assumption that one serving of food is to be cooked, for example, the cooking appliance may be adapted to two or four servings, etc., by changing the control conditions (for example, one parameter, the heating time) using a built-in program in response to an external command.

Furthermore, in the following description, the recipe data CD for the cooperative cooking mode KM1 will be mainly described as consisting of two steps, for example, cooking step 1 and cooking step 2.
For example, in the case where the first heating means HM1 is used in cooking process 1, the cooking device 1 acquires recipe data in two stages: a first part M1 that sets the operation content of cooking process 1 to be used in cooking process 1, and a second part M2 that sets cooking process 2 that uses the second heating means HM2.
That is, it is composed of two parts: a first part M1 that sets cooking process 1 using the first heating means HM1, and a second part M2 that sets cooking process 2 using the second heating means HM2. Note that even in the case where the second heating means HM1 is used in cooking process 1, the cooking appliance 1 similarly acquires the setting information for cooking process 1 and cooking process 2 separately. Note that the first part M1 corresponds to the "setting information A," and the second part M2 corresponds to the "setting information B."

In the following embodiments, the above-mentioned forms of recipe data CD will not be particularly distinguished from one another. Furthermore, in the case of the collaborative cooking mode KM1, an example in which there are two cooking steps will be described, but there may be three or more cooking steps.

The "display screen" in the following embodiments includes a liquid crystal display screen using a liquid crystal display element (liquid crystal panel) and a display screen using other light-emitting methods (organic EL panel, etc.).
It also includes "pop-up screens" that automatically appear within the display screen. A "pop-up" is a separate window that automatically appears (starts up and begins displaying) on the screen of an Internet browser (also called a "web browser").
For example, in the terminal display unit (display screen) 216 of the communication terminal 200 described later, a first screen 216A, a second screen 216B, etc. will be described, but these may also be configured as pop-up screens.

Embodiment 1.
(1. Configuration of the cooking system)
A first embodiment of the present disclosure is shown in FIGS. 1 to 25. FIG.
Referring to FIG.
The cooking system of the first embodiment is configured to include a cooking appliance 1, a smartphone 200 (also called a high-function communication terminal, but collectively referred to as a "communication terminal" in the following description) having the function of performing two-way wireless communication between the cooking appliance 1, and a cloud server 300, which is a type of information processing means. Note that the communication terminal 200 may be a device other than a smartphone, such as a tablet terminal or a personal computer with a communication function. These devices are collectively referred to as the communication terminal 200 in the first embodiment.

The communication terminal 200 performs wireless communication 202WF using a communication method such as Wi-Fi (registered trademark) with a wireless router 201 (Figure 2) installed in the house (not shown) where the cooking appliance 1 is used.

The cooking appliance 1 can acquire at least recipe data CD1 through wireless communication 330 with the communication terminal 200. Note that recipe data CD2 acquired by the cooking appliance 1 via the cloud server 300, which will be described later, will be described later.
The communication terminal 200 performs wireless communication 202BT with the cooking appliance 1 using a communication method such as Bluetooth (registered trademark) (see FIG. 2).

The communication terminal 200 accesses the cloud server 300 in an external space via the wireless router 201 (Figure 2) and a network NW such as the Internet. The cloud server 300 has at least one recipe data providing server 301.

The recipe data providing server 301 is equipped with a recipe DB (database) 302 that stores data on recipes for performing various cooking methods, and the communication terminal 200 accesses a recipe providing site operated by the recipe data providing server 301 and acquires (downloads) various recipe data CD1 from the recipe DB 302.

As will be explained in detail later, the recipe data CD1 includes commands (command data) that specify the heating means and control conditions (including, but not limited to, at least one of heat, heating time, temperature, etc.) so that a specific food item (e.g., hamburger steak) can be cooked in the cooking appliance 1. However, as mentioned above, the recipe data CD1 may contain only unique data that identifies one recipe data CD1 for executing a specific cooking menu.

In the following explanation, recipe data may be referred to with reference numbers such as CD1, CD2, etc., but the contents of the recipe data do not necessarily differ depending on the reference number; in some cases, they may be the same. These reference numbers (CD1, CD2) are used based on the entity that sent the recipe data, making it easier to understand. When using a unified reference number for recipe data, "CD" will be used.

The cooking appliance 1 shown in Figure 1 comprises a first heating means HM1 located below a top plate 3 (described in Figure 2 and subsequent figures) that covers the top surface of the cooking appliance 1, a second heating means HM2 that supplies microwaves to the inside of a heating chamber 6 (see Figure 3) formed inside the cooking appliance 1, and a third heating means HM3 that is located inside or outside the heating chamber 6 and raises the temperature of the internal space of the heating chamber 6 to heat it.

If the upper surface of the top plate 3 is defined as the "first location," then induction heating means is used as the first heating means HM1 to heat an object to be heated (such as a pot or frying pan made of magnetic metal) placed in this first location. Alternatively, the first heating means HM1 could be a gas combustion device equipped with a gas burner that heats pots made of magnetic or non-magnetic metal.

If we define the enclosed space located away from the first location as the "second location," then the interior of the heating chamber 6 (see Figure 3) would be that second location.

The cooking device 1 has three cooking modes (main cooking modes).
The first cooking mode is the above-mentioned cooperative cooking mode KM1.
The second cooking mode is the combined cooking mode KM2.
The third cooking mode is the single cooking mode KM1.

Single cooking mode KM3 is a cooking mode in which the first heating means HM1 and the second heating means HM2 are each driven independently (independently).

The composite cooking mode KM2 is a cooking mode in which the second heating means HM2 and the third heating means HM3 are driven simultaneously, or one of them is driven first and the other is automatically driven later, as a method of cooking a single food item. Even when the second heating means HM2 and the third heating means HM3 are driven simultaneously, whether the heating ends at the same time or at different times is still a single operating pattern belonging to the "composite cooking mode" KM2.

The combined cooking mode KM2 has at least three patterns: a pattern in which the second heating means HM2 and the third heating means HM3 are driven simultaneously from the beginning (RG control mode 1); a pattern in which the third heating means HM3 starts driving after the second heating means HM2 (RG control mode 2); and a pattern in which the third heating means HM3 is driven first, and then the driving of the second heating means HM3 is automatically switched over to. In these RG control modes 1 to 3, the switching of the heating means is performed automatically when cooking begins in the heating chamber 6 (see Figure 3).

Unlike the linked cooking mode KM1, the combined cooking mode KM2 does not have a "cooking menu" corresponding to a specific food item (e.g., hamburger steak). In other words, it provides a "control menu" for each pattern for driving the second heating means HM2 and the third heating means HM3. A single control pattern can accommodate multiple food items (e.g., thawing meat or boiling vegetables).

For example, one of the "control menus" is the aforementioned "RG control mode 1." In the RG control mode (RG combined cooking mode), a variety of dishes can be cooked. One of the "control menus," for example, the aforementioned "RG control mode 1," is controlled by recipe data that defines the control mode, but is not set for each specific dish to be cooked. RG control mode 1 is one of the aforementioned sub-cooking modes.

In other words, the composite cooking mode KM2 is an operating pattern that operates two or more heating sources (the second heating means HM2 and the third heating means HM3) in a predetermined sequence and has multiple "control menus."

In contrast to this, the cooperative cooking mode KM1 with a cooperative cooking menu applies recipe data (corresponding to specific foods) to heat and cook foods placed inside the heating chamber 6 and above the top plate 3 in a predetermined order.
That is, the contents of the recipe data are different between the composite cooking mode KM2 and the cooperative cooking mode KM1.

In the following description, when a type of control mode, such as a driving (energizing) pattern of a heat source, is indicated, it is called a "control menu." For example, "thawing" is one of the control menus.
On the other hand, when specifying the food to be cooked, the name of the dish, etc., it is called a "cooking menu." For example, "hamburger steak" is one of the cooking menus.

The cooking appliance 1 has the ability to execute a coordinated cooking mode KM1 in which the first heating means HM1 and the second heating means HM2 are driven with a time difference determined depending on the user's operation. In other words, between cooking process 1 and cooking process 2, there is a "heating pause period" (also called a "transition period") that changes depending on the timing of the user's operation.

The cooperative cooking mode KM1 has a pattern in which cooking step 1 is performed by the first heating means HM1, and a pattern in which cooking step 1 is performed by the second heating means HM2.
For example, in order to move on to cooking process 2 after completing cooking process 1 using the first heating means HM1, the food to be cooked is moved into the heating chamber 6, and then the second heating means HM2 begins to operate, so there is a ``heating pause period'' (transition period TR) between cooking process 1 and cooking process 2 during which no heating operation is performed.

In this cooperative cooking mode KM1, the recipe data CD is prepared for each specific food to be cooked (for example, hamburger steak, roast beef, or gratin).
The recipe data CD specifies the heating means to be used, the order in which the heating means are driven, and the control conditions for the heating means (including at least one of heat, heating time, temperature, etc.) for cooking step 1 (first part M1) and cooking step 2 (second part M2). In other words, setting information for cooking step 1 and setting information for cooking step 2 are transmitted to the cooking appliance 1.

The recipe data CD is stored in both the cooking appliance 1 and the recipe DB 302. The type of recipe data CD in the recipe DB and the type of recipe data CD stored in the cooking appliance 1 do not have to be the same. For example, recipe data CD for new linked cooking modes KM1 may be added sequentially to the recipe DB 302, and recipe data CD for composite cooking menus may be accumulated sequentially.

In the following description, the cooking menus that are initially stored (memorized) in the cooking appliance 1 are referred to as "basic menus." The cooperative cooking mode KM1 has a total of eight basic menus.
In contrast, a cooking menu that the user acquires from the recipe data providing server 301 using the communication terminal 200 and provides to the cooking appliance 1 as recipe data is called an "additional menu."

When the cooking appliance 1 acquires the recipe data CD for executing the cooperative cooking mode KM1 from the communication terminal 200, the data is one cooking menu unit selected by the user on the communication terminal 200. In other words, it is one type of cooking unit. This is not limited to the cooperative cooking mode KM1, but is also common to the combined cooking mode KM2 and the single cooking mode KM3.

In other words, in the heating cooker 1, for example, a control menu called "warming" can be selected in the composite cooking mode KM2, but the recipe data CD provided to the heating cooker 1 from the communication terminal 200 is not in units of such control menus, but in units of the aforementioned "cooking menus."
Therefore, although the control menu for microwave heating and the like includes various control menus such as "warm,""manualmicrowave,""pre-boil leafy vegetables,""pre-boil root vegetables," and "thaw meat," which will be described later, the communication terminal 200 does not provide recipe data CD for each of these control menus. For example, in the case of thawing, the communication terminal 200 provides recipe data (including identification information) called "thawing of XX," which specifies the object to be heated, "XX."

As described above, the communication terminal 200 requests the recipe data providing server 301 to provide recipe data CD for the desired food to be cooked, and downloads the recipe data CD1 corresponding to the desired recipe (see Figure 1).

The communication terminal 200 can transmit recipe data CD2 corresponding to one recipe, which is generated by the recipe data providing server 301 and acquired from the server 301, to the cooking appliance 1 (see FIG. 1).
To use this recipe data acquisition function, a user of the cooking appliance 1 accesses the recipe providing site (recipe data providing server 301) and installs an application for selecting recipes (hereinafter referred to as the "recipe selection app") on the communication terminal 200.

When the user installs the recipe selection app, they register "device identification information" (described below), such as the model name of the cooking appliance, as an initial setting. This registration allows the user to obtain recipe data CD corresponding to the rated specifications of cooking appliance 1 (such as the heating capacity of each heating means HM1 to HM3) from the recipe providing site (recipe data providing server 301).

The user also uses the recipe selection app to pair the communication terminal 200 with the cooking appliance 1, establishing direct wireless communication 202BT between the communication terminal 200 and the cooking appliance 1. This wireless communication 202BT may use near field communication (NFC).

In FIG. 2, 202WF indicates wireless communication between the communication terminal 200 and the wireless router 201. The communication method for wireless communication 202BT between the communication terminal 200 and the cooking appliance 1 uses Bluetooth (registered trademark), which is one of the short-range wireless communication standards. Furthermore, wireless communication 202WF between the communication terminal 200 and the wireless router 201 uses a wireless LAN communication method such as Wi-Fi (registered trademark).

Although not shown in FIG. 1, in the cooking system of this embodiment 1, recipe data CD (corresponding to one recipe) created by the user can be sent by the communication terminal 200 to the recipe providing site (recipe data providing server 301), temporarily stored in the recipe DB 302, and then provided to the cooker 1. In other words, even if the communication terminal 200 is located far away from the house in which the cooker 1 is installed (for example, while away from home), the recipe data CD of the communication terminal 200 can be conveniently stored in the recipe data providing server 301.

A wireless router 201 (see FIG. 2) may be interposed between the cooking appliance 1 and the cloud server 300.
In the following description, when describing the network NW such as the Internet line, the unified symbol "NW" will be used.

The "device identification information" of the cooking appliance 1 is unique information used to identify the cooking appliance 1. Specifically, this information is important information required when communicating information, and includes the MAC address, the manufacturer name of the cooking appliance 1, the model name, the type number, the serial number, etc.

The cloud server 300 has a function of acquiring information about the current status of the cooking appliance 1, such as operation, stoppage, and standby state, via the network NW.
The cloud server 300 is connected to the target cooking appliance 1 using the device identification information.

In addition to the recipe database 302, the cloud server 300 also contains an information server (not shown) that transmits useful information to the cooking appliance 1 and the communication terminal 200. The cooking appliance 1 periodically (e.g., repeatedly at 5- or 10-minute intervals) performs a process of wireless communication with the cloud server 300, separate from the wireless communication with the communication terminal 200. If an abnormality is detected or determined to exist in the "status information" (described below) on the cooking appliance 1 side during this periodic communication, this triggers a process of notifying or querying the cloud server 300 each time to obtain information for maintaining proper operation. If no abnormality is found, the cooking appliance 1 automatically returns to the process of repeatedly performing the periodic communication, and this process continues until the main power switch 20 (see Figure 5), described below, is opened. This will be explained in more detail later.

The information server (not shown) may be, for example, a server installed by an external organization such as an earthquake information provider in a specific region or an electric power company, or it may be a server provided by the manufacturer of the cooking appliance 1.

The cloud server 300 stores and memorizes control application software that enables remote control of the cooking appliance 1. The communication terminal 200, which will be described in detail later, can access the cloud server 300 and download (load) the control application software to achieve the remote control described above.

The communication terminal 200 in this first embodiment has the function of transmitting and receiving signals via short-range communication when placed within a few centimeters of (or even in contact with) the input/output unit of the cooking appliance 1. This short-range communication refers to an international standard technology for wireless communication known as Near Field Communication (abbreviated as NFC).

In this NFC communication, a so-called wireless tag (NFC tag) is embedded in the induction cooking appliance 1 .
On the other hand, it is also possible to send control data from the communication terminal 200 side to the NFC storage unit of the cooking appliance 1, and control the cooking appliance 1 in accordance with the control data.

Next, FIG. 2 will be described.
Reference numeral 400 denotes kitchen furniture in which the cooking appliance 1 and the like are installed. Reference numeral 400D denotes a water inlet for a water supply provided in the kitchen furniture 400.
Reference numeral 201 denotes a wireless router capable of wireless communication with the cooking appliance 1. This wireless router 201 also serves as an access point to a network NW such as the Internet.

203 is a monitoring device equipped with a human detection sensor that monitors the interior space of the kitchen (living space) 500 (not shown), particularly the presence of a person within a predetermined range (e.g., within 2 m) in front of the cooking appliance 1. This monitoring device 203 continuously or repeatedly checks the interior of the kitchen 500 at short intervals (e.g., every 5 seconds) and transmits a signal indicating the presence or absence of a person to the cloud server 300 and the cooking appliance 1. For example, a monitoring result signal may be sent to the wireless router 201 and provided to the cloud server 300. When the cloud server 300 receives a start-up signal from the cooking appliance 1, it continues to provide a monitoring signal until the cooking appliance 1 finishes operation, and when the cooking appliance 1 determines whether a specific condition is met, the monitoring signal is used as one of the basic data for the determination.

The cooking device 1 has an outer shell formed by a hollow, box-shaped main body 2 and a top plate 3 that covers the entire upper surface of the main body 2.
An object to be heated (such as a pot made of magnetic metal) is placed on the top plate 3 and is induction heated by an IH coil 9 (reference numerals 9C, 9L, and 9R shown in FIGS. 3 and 4). That is, the top plate 3 has heating ports 4 consisting of a left heating port 4L, a right heating port 4R, and a center heating port 4C.

The three heating ports 4L, 4C, and 4R and the heating chamber 6 described below may be collectively referred to as the "heating section," in which case the reference symbol HP will be used.

An exhaust vent cover 5 is provided on the rear side (back side) of the top plate 3. The exhaust vent cover 5 is made of a punched metal or lattice-shaped metal member with numerous small through-holes, allowing for ventilation throughout and low airflow resistance. Exhaust air released from inside the main body 2 of the cooking appliance 1 passes through the exhaust vent cover 5 and exits the cooking appliance 1.

A door (heating door) 7 is provided on the front of the main body 2 of the cooking appliance 1, opening and closing the front opening of the heating chamber 6 (see Figure 3) located inside the main body 2. The door 7 is provided with a handle 8 for opening and closing it.

(2. Detailed configuration of the cooking device)
Next, a specific configuration of the cooking device 1 will be described with reference to FIGS.
3 will be described. Fig. 3(A) is a plan view of the cooking appliance 1. Fig. 3(B) is a front view of the cooking appliance 1.
Fig. 3 does not show the kitchen furniture 400 described in Fig. 2. The cooking device 1 is a built-in induction cooking heater that is incorporated into kitchen furniture 400 that has a cooking table on top.
The cooking device 1 has a main body 2 and a top plate 3 placed on the main body 2 .
The top plate 3 is exposed above the kitchen countertop that forms the top surface of the kitchen furniture 400.

The top plate 3 is composed, for example, of a heat-resistant crystallized glass plate and a metal frame attached to surround the glass plate. Three heating ports 4 are provided on the top surface of the top plate 3: the left heating port 4L, the right heating port 4R, and the center heating port 4C.

The left heating port 4L, right heating port 4R, and center heating port 4C are where metal cooking containers such as pots or frying pans (also referred to as the "heated object" N for the first heating means HM1) are placed and heated. Guide marks (not shown) are printed on the top surface of the top plate 3, corresponding to the left heating port 4L, right heating port 4R, and center heating port 4C, respectively, to indicate the position where the heated object should be placed.

When the cooking appliance 1 is viewed from above, the IH coil 9C of the central heating port 4C is disposed directly above the center line CL (see FIG. 6) in the front-rear direction that passes through the center of the top plate 3 from left to right.
Further, on the center line CL, a central heating power display unit 16M, an integrated display unit 15, and a central operation unit 17 are arranged so as to be aligned in a straight line.
3(B), reference numeral 7 denotes a door that can be opened and closed to cover the front opening of the heating chamber 6 (not shown) formed inside the main body 2. A handle 8 is provided at the upper end of this door 7. A viewing window 7W is formed in the center of the door 7 and is covered with transparent heat-resistant glass and a metal shielding plate (not shown) with numerous through holes for blocking microwaves.

The integrated display unit 15 has a horizontally long LCD display screen. The left heating power display unit 16L, center heating power display unit 16M, and right heating power display unit 17R each display the heating power level using multiple light-emitting elements (such as LEDs, not shown) and do not have a display screen. Details will be explained later.

Next, a description will be given of Fig. 4. Fig. 4 is a vertical cross-sectional view taken along line XX in Fig. 3.
Reference numeral 19S denotes a metal partition plate that divides the internal space of the main body 2 into two, upper and lower spaces. Above this partition plate 19S is a (first) installation space 19A for the first heating means HM1. Below the partition plate 19S is a (second) installation space 19B that houses the heating chamber 6 and the like.

The installation space 19A accommodates the IH coils 9 (9C, 9L, 9R) at positions corresponding to (directly below) the three heating ports 4L, 4R, 4C.
That is, a right IH coil 9R serving as a right induction heating means is provided below the right heating port 4R, and a central IH coil 9C serving as a central induction heating means is provided below the central heating port 4C. A left IH coil 9L serving as a left induction heating means is provided below the left heating port 4L.

In the following description, unless otherwise specified, the IH coils 9C, 9L, and 9R and their drive circuits (high-frequency power supply circuits such as inverter circuits, not shown) will be referred to as the first heating means HM1.

A temperature sensor group 30 (see Figure 5) consisting of multiple temperature sensors (not shown) is mounted near the IH coils 9C, 9L, and 9R to detect the temperature of the top plate 3 and cooking vessel (heated object N). One of the temperature sensors 30A (not shown) that makes up the temperature sensor group is a contact temperature sensor such as a thermistor. The other temperature sensor 30B (not shown) is a non-contact temperature sensor such as an infrared sensor.

The heating chamber 6 in the installation space 19B inside the main body 2 is surrounded by metal walls such as stainless steel, and is a space for heating the food (foodstuffs, ingredients) contained within this heating chamber 6.

The food to be cooked may be placed on a heat-resistant plastic container, a porcelain or heat-resistant glass dish, or may be placed inside a container and placed in the heating chamber 6; in such cases, the dish or container may be referred to as the "heated container." However, because these containers are not induction heated by the IH coils 9C, 9L, and 9R, even if they are placed on the heating port 4 of the top plate 3, they are not referred to as the "heated object" N of the IH coils 9C, 9L, and 9R.

A horizontally long (rectangular) opening (not shown) is formed in the front of the heating chamber 6 for inserting and removing the food to be cooked. The opening in the front of the heating chamber 6 is covered by the door 7, which can be opened and closed freely. The door 7 is supported by the main body 2 so that it can rotate freely via hinges and arms (not shown). This allows the door 7 to open forward to a horizontal position with its lower end as the fulcrum (center of rotation). The door 7 may also be pulled forward integrally with a support member (a structure such as a shelf, not shown) that supports the heated container from below, by means of a slide rail (not shown).

The door 7 is provided with an open/close detector 10 for detecting whether the door 7 is open or closed. The open/close detector 10 is, for example, a microswitch or an infrared sensor. A microwave oscillator 11 is provided behind the heating chamber 6 to heat the food placed in the heating chamber 6. The microwave oscillator 11 is, for example, composed of a magnetron, and irradiates microwaves into the heating chamber 6 to heat the food placed in the heating chamber, a process known as microwave heating.

The heating means including the microwave oscillator 11 and its drive circuit (a high-frequency power supply circuit such as an inverter circuit, not shown) may be referred to as the second heating means HM2.

The heating chamber 6 is equipped with an upper radiant heat heating means 12a and a lower radiant heat heating means 12b that heat the food from above and below. The upper radiant heat heating means 12a is located on the ceiling wall surface on the outside or inside of the heating chamber 6, and the lower radiant heat heating means 12b is located on the inside or outside wall surface of the heating chamber 6. Both are sheath heaters.

The upper radiant heat heating means 12a and the lower radiant heat heating means 12b may be other types of radiant heat heating means other than sheath heaters. For example, mica heaters, carbon heaters, etc. may be installed outside the heating chamber 6. Figure 4 shows an example in which the upper radiant heat heating means 12a and the lower radiant heat heating means 12b are both installed in close contact with the outer wall surface of the heating chamber 6.

The heating means, including the upper radiant heat heating means 12a and the lower radiant heat heating means 12b, and their drive circuits (not shown), may be referred to as the third heating means HM3. The upper radiant heat heating means 12a and the lower radiant heat heating means 12b may be collectively referred to as the "radiant heat heating means," in which case the reference numeral "12" is used.

The heating chamber 6 is provided with an infrared sensor 13 as a non-contact temperature sensor to detect the temperature of the food being cooked inside the heating chamber 6 without contact. The temperature range detected by this infrared sensor 13 is set to, for example, -20°C to 100°C. This allows the degree of heating of the food to be detected accurately in real time, in increments of 1°C, for example. This infrared sensor 13 also constitutes one sensor in the group of temperature sensors 30 (see Figure 5).

The heating chamber 6 is also provided with a contact-type temperature sensor (e.g., a thermistor sensor) 14, which is an interior temperature sensor that detects the ambient temperature inside the heating chamber 6 or the wall temperature of the heating chamber 6.

The thermistor sensor 14 detects temperature by detecting changes in electrical resistance, and therefore the upper limit of the temperature it can detect is approximately 250°C. This thermistor sensor 14 also constitutes one sensor in the temperature sensor group 30. Note that this thermistor sensor 14 may be installed in two locations, near the bottom and ceiling of the heating chamber 6, as shown in Figure 4.

Next, FIG. 5 will be described.
FIG. 5 is a control block diagram showing the main functions of the cooking appliance 1.
As shown in FIG. 5, the cooking appliance 1 includes a control device 22 that performs integrated control of the entire cooking appliance 1.

The control device 22 is an electronic circuit board mounted with electronic components such as control circuits that control the operation of each component of the cooking appliance 1. The control device 22 individually controls the drive conditions of the left IH coil 9L, right IH coil 9R, and center IH coil 9C based on input signals from the central operation unit 17 and right operation unit 18, as well as the temperature of the object to be heated on the top plate 3.

The control device 22 individually controls the operating conditions of the central IH coil 9C, microwave heating means 11, upper radiant heat heating means 12a, and lower radiant heat heating means 12b based on input commands from the central operation unit 17, the temperature of the heated object on the top plate 3, and the detection results of the infrared sensor 13 and thermistor sensor 14.

In addition, the control device 22 individually displays the input heating power values on the left heating power display unit 16L, the central heating power display unit 16M, and the right heating power display unit 16R based on input commands from the central operation unit 17 and the right operation unit 18.

Furthermore, the control device 22 displays the open and closed states of the door 7 on the integrated display unit 15 based on the open and closed signals for the door 7 from the open/close detection unit 10.

The control device 22 has a storage device 21 that stores various programs and parameter data used to control the cooking appliance 1 (hereinafter collectively referred to as "control data"), as well as display control data (hereinafter referred to as "display condition data") displayed on the integrated display unit 15 and each heat display unit 16L, 16M, 16R. The control device 22 also activates the audio notification unit 49 as needed, and audibly notifies the user of the operating status of the cooking appliance 1.

The control device 22 stores data in a fixed format, including information on various programs and parameters used for cooking control by the heating control unit 23 (described below), in the recipe data storage unit 21A of the storage device 21. This data is the recipe data CD mentioned above. As will be explained later, the cooking appliance 1 is initially provided with recipe data CD corresponding to each of a total of eight cooking menus (the "basic menus" mentioned above) for executing the linked cooking mode KM1. The additional menus mentioned above can also be additionally stored in this recipe data storage unit 21A.

In the following description, the setting information (including setting information A and setting information B) corresponding to the basic menu will be referred to as "setting information X," and the setting information corresponding to the additional menu will be referred to as "setting information Y" to distinguish them. That is, the setting information Y corresponding to the additional menu that the user has acquired from the communication terminal 200 or the like can be stored in the recipe data storage unit 21A. Therefore, acquiring setting information Y increases the amount of setting information Y that can be stored in the recipe data storage unit 21A. In other words, it is possible to increase the number of cooking menus that can be implemented.

The recipe data CD relating to the "additional menu" and the "display condition data" can be acquired by the cooking appliance 1 from an external device such as the communication terminal 200 for each individual cooking menu, and if there are multiple cooking steps, for each cooking step.

Reference numeral 23 denotes a heating control section that performs integrated control of the overall heating operation of the cooking appliance 1, and is mainly composed of a microcomputer.
Reference numeral 24 denotes a data acquisition unit, which is capable of acquiring the recipe data CD from the communication terminal 200 or the cloud server 300 via the communication unit 25. In addition, the display condition data may also be acquired from the communication terminal 200 or the cloud server 300 via the communication unit 25.

The communication unit 25 communicates wirelessly with the outside, and has a function of performing wireless communication 330 (330BT) with the communication terminal 200 as shown in Figures 1 and 2. Alternatively, it has a function of performing wireless communication with the cloud server 300 via the network NW.
The communication section 25 has a first communication section 25A (not shown) and a second communication section 25B (not shown) that correspond to at least two communication methods, as will be described later.
First communication unit 25A is compatible with Bluetooth (registered trademark), which is the communication method used for communication with communication terminal 200. Second communication unit 25B (not shown) is compatible with a wireless LAN communication method such as Wi-Fi (registered trademark), which is used for communication with wireless router 201 (see FIG. 2), and therefore has a function compatible with this communication method.

Reference numeral 26 denotes a permission condition determination unit that performs a process of determining whether cooking in the cooperative cooking mode KM1 or the combined cooking mode KM2 is permitted.
Reference numeral 27 denotes a power supply circuit, which supplies constant voltage power to the control device 22. Reference numeral 20 denotes a main power switch inserted into the power supply circuit 27, which has an operation button 20A that is opened and closed by the user.
With regard to the recipe data CD relating to the collaborative cooking mode KM1, the permission condition determination unit 26 determines whether cooking is permitted at the stage of receiving the first part M1 that sets cooking process 1, as will be described later, and if permission is not granted at that stage, cooking process 1 cannot be executed, and the process does not proceed to the acquisition step of the second part M2 of cooking process 2.

Reference numeral 28 denotes a limiting unit that limits the acquisition of the recipe data CD.
The restriction unit 28 has the function of restricting the data acquisition unit 24 from acquiring the recipe data CD via the communication unit 25 during the waiting period before starting cooking in the collaborative cooking mode KM1 (i.e., before the "cooking process 1" described below).

Furthermore, the restriction unit 28 has a function of restricting the acquisition of new recipe data CD from the communication unit 25 until the cooking process of one cooking menu is completed, based on recipe data CD acquired from the outside.
The restriction unit 28 may be realized by a single control program of a computer (not shown) that constitutes the control device 22, and it is not necessarily required that the restriction unit 28 be configured separately on hardware from the control device 22.

As shown in FIG. 5, the right operation section 18 has an input key 29 for selecting a voice input mode.
Reference numeral 31 denotes a voice signal receiving unit that receives voice uttered by the user with a microphone (not shown) and converts the voice into a predetermined voice signal while the voice input mode is selected.

Meanwhile, the control device 22 is equipped with an audio signal analysis unit 32 that receives audio signals from the audio signal receiving unit 31 and analyzes the content of the audio. The audio signal analysis unit 32 compares the content of the audio received by the audio signal receiving unit 31 with information in the audio database stored in the storage device 21, analyzes the content of the audio, and transmits the analysis results to the heating control unit 23.

33 is an input processing unit. This input processing unit 33 receives an input signal from the input keys 29 of the right operation unit 18 and switches its own input reception mode to "voice input mode 1." It also controls the input signal analysis unit 34. Furthermore, it receives the analysis results from the voice signal analysis unit 32 and transmits control data to the heating control unit 23.

5, reference numeral 35 denotes a human presence sensor. This human presence sensor 35 also has a receiving unit (not shown) that emits an ultrasonic or infrared signal forward of the cooking appliance 1 and receives the reflected wave. Note that no dedicated circuit is provided for processing the signal received by the receiving unit, and the control device 22 analyzes the received signal to determine whether or not a human is present.
When an infrared sensor is used as the human detection sensor 35, the infrared sensor is installed facing forward from the cooking appliance 1 and detects infrared rays emitted from a heat source present within a predetermined range from the cooking appliance 1. In other words, infrared rays emitted by a user can be detected even if they are not emitted from the infrared sensor 35 itself, and the control device 22 can determine whether a user is present within the predetermined range by receiving a detection signal from the infrared sensor (human detection sensor) 35. Note that the human detection determination by the human detection sensor 35 is normally repeated at regular intervals (for example, every 5 seconds), but in the case of the integrated cooking mode KM1, the determination interval may be set longer during the "heating pause period" described below.

As shown in a dashed frame in FIG. 5, the audio notification unit 49 and the integrated display unit 15 may be collectively referred to as the "notification unit," and in this case, the reference numeral 40 is used.
The central heating power display unit 16M, the left heating power display unit 16L, and the right heating power display unit 16R are provided with a number of light-emitting elements 37A (not shown) composed of LEDs or the like. The light-emitting elements 37A are regularly arranged with two or more light-emitting elements of different luminous colors, and depending on the luminous state of the multiple light-emitting elements, the user is given the visual effect of seeing the luminous color change. This will be explained in Figures 9 to 12.

The input signal analysis unit 34 individually analyzes the input signals transmitted from the central operation unit 17 and the right operation unit 18. Therefore, it has a discrimination function that determines whether the voice input mode switching command has been received, for example, from the input key 29. If it determines that the input mode switching command has been received, it issues a switching command to switch the input mode from "touch input mode" to "voice input mode."

As will be described in detail in FIGS. 6 and 7, the central operating section 17 is made up of two sections: a front operating section 17F and a rear operating section 17B.
As shown in FIG. 5, the input operation section 36 of the cooking appliance 1 is made up of three operation sections: the front operation section 17F, the rear operation section 17B, and the right operation section 18.
Reference numeral 37 denotes a light emission control unit, which illuminates a main power on indicator 38 (described later) with red light from below while the main power is on to indicate whether the power is on or not. It also controls the light emission of the heat power indicators 16 (16L, 16M, 16R) and the central operation unit 17.

Reference numeral 39 denotes a timing circuit that measures the elapsed time from the start of cooking and reports the measurement result in one-second increments. This timing circuit may be implemented by software on a microcomputer that constitutes part of the control device 22, and does not have to be a separately configured (dedicated) clock circuit on hardware.

Next, FIG. 6 will be described.
FIG. 6 is an enlarged plan view of the integrated display unit 15, the central operation unit 17 (rear operation unit 17B, front operation unit 17F) and the right operation unit 18 of the cooking appliance 1. As shown in FIG.
When the cooking appliance 1 is viewed from above, the center of the IH coil 9C of the central heating port 4C is located directly above the center line CL in the front-rear direction that passes through the center of the top plate 3 from left to right.
Directly above the center line CL, the IH coil 9C of the central heating port 4C, the central heating power display unit 16M, the integrated display unit 15, and the central operation unit 17 are arranged in a straight line (in the front-to-back direction).
A central operating unit 17M is disposed directly above the center line CL, and a left operating unit 17L and a right operating unit 17R are disposed on either side of the central operating unit 17M.

A right heating power display section 16R is disposed adjacent to the right side of the integrated display section 15.
The right operating unit 18 is arranged a short distance to the right of the front operating unit 17F, along a left-right reference line (straight line) BL that crosses the front edge of the front operating unit 17F directly to the side.
An operation button 20A of the main power switch 20 is disposed at the right end of the right operation section 18, and the input keys 29 are disposed adjacent to the left side thereof.

The integrated display unit 15 is a single LCD display in terms of hardware, but as shown in Figure 6, it has three display areas: a first display area 15L on the left, a second display area 15M in the center, and a third display area 15R on the right, and it is possible to display different content in each of these display areas.

The three display areas 15L, 15M, and 15R may also be linked together as needed to form a single (large-area) display area depending on the display situation, and may display one or more purposes. In the following explanation, the first display area 15L will be referred to as the first area (left area) 15L. The second display area 15M will be referred to as the second area (center area) 15M. The third display area 15R will be referred to as the third area (right area) 15R.

The first to third areas 15L, 15M, and 15R are basically displayed so that they have the same effective display area, as shown in Fig. 6. In other words, the width W1 of the first area 15L, the width W2 of the second area 15M, and the width W3 of the third area 15R are all the same.
In the first embodiment, the first to third areas 15L, 15M, and 15R are illustrated as being divided by a boundary line 15S, but such boundary line 15S does not have to be displayed on the actual display screen. In other words, the user does not have to be able to strictly visually recognize the individual ranges (in a plan view) of the first to third areas 15L, 15M, and 15R.

The first area 15L basically displays various control information, sub-cooking modes, etc. for cooking performed using the left heating port 4L.
Similarly, the third area 15R basically displays various control information, cooking modes, etc. for cooking performed using the right heating port 4R.
The second area 15M basically displays various control information and sub-cooking modes for cooking performed in the central heating port 4C and cooking performed in the heating chamber 6. However, this second area 15M does not simultaneously display information for cooking performed in the central heating port 4C and cooking performed in the heating chamber 6. The heating means for the heating chamber 6 (second heating means HM2, etc.) and the IH coil 9C, which is the heating means for the central heating port 4C, are integrally controlled by the control device 22 so as to be used exclusively.

The left operating unit 17L for cooking using the left heating port 4L includes a left ON/OFF switch 41L that starts and stops cooking using the left IH coil 9L, and a pair of left shared switches 42L that can be used to set the control conditions (heat power and cooking time during cooking, etc.) for the left IH coil 9L and to select a sub-cooking mode.

The right operating unit 17R for cooking using the right heating port 4R includes a right ON/OFF switch 41R, which starts and stops cooking using the right IH coil 9R, and a pair of right shared switches 42R, which can be used to set the control conditions (heat power and cooking time during cooking, etc.) for the right IH coil 9R and select a sub-cooking mode.

The central operating unit 17M, which is shared for cooking in the heating chamber 6 and the central heating port 4C, is equipped with a central on/off switch 41M that starts and stops cooking using the central coil 9C, and a pair of central shared switches 42M on the left and right that can set the control conditions (heat power and heating time during cooking, etc.) using the central IH coil 9C and can also select a sub-cooking mode.
The central shared switch 42M can set the control conditions (heat power and heating time during cooking) of the heating means of the heating chamber 6 (second heating means HM2 and third heating means HM3).

The left turn-on switch 41L, the center turn-on switch 41M, and the right turn-on switch 41R will be referred to as the left turn-on key 41L, the center turn-on key 41M, and the right turn-on key 41R in the following description.
In the following description, the left shared switch 42L, the center shared switch 42M, and the right shared switch 42R will be referred to as a left shared key 42L, a center shared key 42M, and a right shared key 42R.

As shown in Figure 6, the left ON/OFF key 41L and left shared key 42L that make up the left operation unit 17L are positioned near the front of the first area 15L within the width dimension W1 of the first area 15L so that their correspondence with the left IH coil 9L, which is the target of operation input, is clear.

Similarly, the right ON/OFF key 41R and right shared key 42R that make up the right operation unit 17R are positioned near the front of the third area 15R, within the width dimension W3 of the third area 15R, so that their correspondence with the right IH coil 9R, which is the target of operation input, is clear.

Furthermore, the central ON/OFF key 41M and central shared key 42M that make up the central operation unit 17M are positioned near the front of the second area 15M, within the width dimension W2 of the second area 15M, so that the correspondence between them and the central IH coil 9C and heating chamber 6, which are the targets of operation input, is clear.

The right operation section 18 has various switches (input keys) arranged thereon for manual operation.
A timer switch 43 can automatically stop cooking by any of the first to third heating means HM1 to HM3 after a desired time set by the user has elapsed. Therefore, for example, cooking in the heating chamber 6 can be automatically stopped after the set time has elapsed.
Reference numeral 44 denotes a setting key for changing the set time of this timer switch 43. The timer switch 43 has two setting keys, one of which can lengthen the set time by pressing or touching, and the other of which can shorten the set time by pressing or touching, and these are arranged adjacent to each other on the left and right.

Reference numeral 45 denotes a function setting key for setting various functions, such as various operations and displays of the entire cooking appliance 1, so that the user can set them as desired.
When the function setting key 45 is pressed, the control device 22 switches to a "function setting mode" and displays the following "function setting menu" on the display screen of the integrated display unit 15.
(1) Child lock setting (setting to disable operation of various input keys).
(2) Setting the ventilation device to linked mode (ventilation device operation linked to the operation of the cooking appliance 1).
(3) Cleaning guide setting (setting of automatic notification function for when to clean the heating chamber 6 and exhaust port cover 5).
(4) Peak cut setting (select one of four maximum power consumption levels: 5700W, 5000W, 4800W, and 4000W).
(5) Audio guide audio settings.
(6) Audio guide volume setting.
(7) Settings to prevent forgetting to remove food, cooking utensils, etc. from the heating chamber 6 (whether or not to issue an alarm on the audio notification unit 49 and the integrated display unit 15).
(8) HEMS registration settings (settings related to the power usage restriction function of the home power control device).
(9) Time unit setting for timer cooking (change from 1 minute to 5 or 30 minutes).
(10) Switching between beginner mode and normal (expert) mode.
(11) Setting the display priority (specific cooking menu to be displayed as default) of each cooking menu (for example, "hamburger steak") in the cooperative cooking mode KM1.
(12) Setting the display priority (specific control menu to be displayed as default) of each control menu of the combined cooking mode KM2 (for example, "Grill in the microwave" and "Pre-boil leafy vegetables").
(13) Setting the cooking mode to be automatically displayed on the integrated display unit 15 when the door 7 of the heating chamber 6 is opened after the main power switch 20 is turned “ON” (such as the display priority between the linked cooking mode KM1 and the combined cooking mode KM2).

FG indicates the user's fingertips.
As shown in Figure 6, if a user wants to use, for example, the right heating port 4R, they perform input operations within the range of the right operating unit 17R, and the control conditions for cooking with the right heating port 4R, the input results for the sub-cooking mode, the progress of heating cooking, etc. can basically be known in real time from the information displayed in the right area (third area) 15R.

The six (three sets of one pair) common keys 42L, 42M, 42R and the three sets of on/off keys 41L, 41M, 41R mentioned above may be push-button type input keys (switches), or may be configured as touch-type keys such as capacitance type keys that allow input by utilizing the change in capacitance when the user lightly touches them with their fingertip FG.
In Figure 6, reference numeral 70 denotes a cooperative cooking mode selection switch (key) provided on the right operation unit 18, which selects cooperative cooking mode KM1 when pressed once. In the following explanation, this will be simply referred to as the "selection key" 70. When this selection key is pressed, a cooperative cooking menu stored in the memory device 41 is called up, and the cooperative cooking menu is displayed, for example, in the central area 15M, in a format where the menu items are displayed one by one in sequence according to a certain rule. The types of cooperative cooking menus and cooking steps will be explained in Figure 27.

Next, FIG. 7 will be described.
FIG. 7 is an enlarged plan view of the integrated display unit 15 and the central operation unit 17 (rear operation unit 17B and front operation unit 17F).
A rear operation unit 17B is disposed in front of the integrated display unit 15, and a front operation unit 17F is disposed adjacent to and further forward than the rear operation unit 17B.

The integrated display unit 15 displays information about the entire cooking appliance 1 and alarm information, and is configured by a liquid crystal display.
As shown in Figure 7, the first area 15L of the display screen of the integrated display unit 15 displays the induction heating power value set by the user on a scale of 1 to 9 when using the left heating port 4L that uses the induction heating means (first heating means) HM1. 48 is the heat power display section, which displays the heat power value itself and the magnitude of the heat power level.
Reference numeral 63 denotes a remaining time display section that shows the "remaining time" of the heating time set by the user. In Fig. 7, it can be seen that the heating power is at the seventh level (e.g., 2500 W) and the remaining time is 7 minutes.

As shown in Figure 7, the second area 15M of the integrated display unit 15 can display identification information 46 of a sub-cooking mode using at least one of the microwave heating means (second heating means) HM2 and the radiant heat heating means (third heating means) HM3.
Furthermore, the second area 15M can also display information about cooking using the central IH coil 9C of the first heating means HM1 that corresponds to the central heating port 4C. Reference numeral 47 denotes a heat source display section that indicates cooking using the central IH coil 9C (single cooking mode KM3).

Reference numeral 46 denotes identification information for a sub-cooking mode, which is displayed in a predetermined position, i.e., the "center in the front-to-back direction," in the first area 15L, second area 15M, or third area 15R. In FIG. 7 , identification information 46, such as a name, abbreviation, or symbol, is displayed to identify a sub-cooking mode called "grilling," a type of cooking using the heating chamber 6. However, when the start of cooking in a sub-cooking mode called "deep-frying" is confirmed by operating the right-on/off key 41R, as in the third area 15R shown in FIG. 7 , the display position of the identification information 46 shifts to a position behind the "center in the front-to-back direction." Furthermore, in one display area (e.g., the first area 15L), only the identification information 46 is displayed, and it is no longer displayed simultaneously with identification information 46A (described later) (the display of identification information 46A disappears).
The identification information 46 may be referred to as "identification information X" to avoid confusion with the identification information 72 of the cooking menu of the cooperative cooking mode KM1.

The three areas 15L, 15M, and 15R may also each display a cancel indicator 46C for canceling the selection of a heating means (first heating means HM1 to third heating means HM3). The sub-cooking mode or heating means specified by the information displayed at the position where the heat source indicator 47 displays "Central IH," i.e., the center of the front-to-back direction of the second area 15M, is selected. In other words, in the state shown in Figure 7, it can be seen that heating cooking using the central IH coil 9C is selected.

As shown in Figure 7, the third area 15R of the integrated display unit 15 can display information about heating and cooking using the right IH coil 9R, which corresponds to the right heating port 4R of the first heating means HM1.
46A is unique identification information, such as a name, abbreviation, or symbol, for identifying the next sub-cooking mode candidate (belonging to the single cooking mode KM3) using the right IH coil 9R. In the example of FIG. 7, the identification information 46A indicating the sub-cooking mode candidate is "frying." When the sub-cooking mode identification information 46A is displayed in the center of the three areas 15L, 15M, and 15R in the front-to-back direction, it is called the sub-cooking mode display area 46. Note that the identification information 46A may also be referred to as "identification information Y."

50 is a set temperature display unit. One example of this set temperature display unit 50 shows the target heating temperature for the preheating process set by the user. In Figure 7, it can be seen that the temperature is set to 180°C for "frying." When the temperature sensor group 30 detects that the bottom surface of the heated object N (not shown), such as a frying pan or deep fryer, has reached 180°C, preheating is complete.

Six (three pairs of) left-common keys 42L, 42M, and 42R are arranged on the rear operation unit 17B. The left-common key 42L (left and right), which corresponds to the first area 15L, is used to set the control conditions (heat power, temperature, heating time, etc.).
For example, each time the right-side shared left key 42L is pressed, the heat setting increases by one level. Conversely, each time the left-side shared left key 42L is pressed, the heat setting decreases by one level. In other words, because these left-side shared left keys 42L are up/down keys, parameters such as heat level, heating time, and temperature displayed in the first area 15L can be displayed in a specific order in the first area 15L. Furthermore, multiple sub-cooking modes (described in detail in FIG. 17 ) can also be displayed one by one in a specific order in the center of the first area 15L.

The set of (left and right) central shared keys 42M corresponding to the second area 15M and the set of (left and right) right shared keys 42R corresponding to the third area 15R are also up/down keys, similar to the left shared key 42L, and are therefore used to set control conditions (heat power, temperature, heating time, etc.) and to select the sub-cooking mode.
The three sets of cut/insert keys 41L, 41M, and 41R are arranged near the front sides of the left operating section 17L, the central operating section 17M, and the right operating section 17R, respectively.

The three sets of ON/OFF keys 41L, 41M, and 41R mentioned above have light-emitting elements (not shown) such as light-emitting diodes (LEDs) located below them so that the state in which each heating method is selected (ON state) and the state in which each heating method is not selected (OFF state) can be distinguished by looking at the ON/OFF keys 41L, 41M, and 41R themselves. The light-emitting operation of these light-emitting elements is controlled by the light-emitting control unit 37 described in Figure 5.

Furthermore, to visually recognize when the input function of each of the three sets of common keys 42L, 42M, and 42R is enabled and disabled, light-emitting elements (not shown) may be placed below each of the common keys 42L, 42M, and 42R, and the light-emitting operation may be controlled by the light-emitting control unit 37.

Next, FIG. 8 will be described.
8 is an explanatory diagram showing input operation steps of the central operation unit 17. For the sake of simplicity, the integrated display unit 15 will be described in two cases, a first area 15L and a third area 15R.
When the main power switch 20 is first turned on, the control device 22 activates the integrated display unit 15. In the first step S1, the "standby initial screen" is displayed, which does not display any specific sub-cooking modes. However, for the sake of explanation, Figure 8 shows an example in which the first area 15L and the third area 15R display the identification information 46 of the sub-cooking mode "Keep Warm," which is designated as the default display as one sub-cooking mode.

In the next step S2, if the user intends to use the right heating port 4R, the "Keep Warm" sub-cooking mode displayed in the third area 15R corresponding to the right heating port 4R can be changed using the right shared key 42R. The right heating port 4R has four sub-cooking modes, as explained in Figure 17. Pressing the right shared key 42R on the left side changes the sub-cooking mode to "Heat," which is defined next to "Keep Warm." The state in which the display content of the third area 15R has been changed in this way is step S3.

Next, as in step S3, while the identification information 46 of the sub-cooking mode "heating" is displayed in the center of the third area 15R, pressing the right ON/OFF key 41R (step S4) confirms the use of the right heating port 4R and the start of the heating operation.
The heating operation in this case is an induction heating operation, and induction heating is started at a predetermined heating power set as a default, for example, heating power 6 (for example, 2000 W).
Since the heating power value can be changed within a certain period of time after the start of the heating operation, the user can increase or decrease the default heating power by pressing the right common key 42R (step S6).

Next, FIG. 9 will be described.
FIG. 9 is an explanatory diagram 1 showing the display states and input operations of the integrated display unit 15, the central operation unit (rear operation unit and front operation unit) 17, the right operation unit 18, and the right firepower display unit 16R.
FIG. 9 shows the state immediately after the heating operation is started at step S5 in FIG.

In FIG. 9, 53R is a change mark indicating that the control conditions can be changed, and may also be displayed in the first area 15L and the second area 15M, in which case the symbols 53L and 53M are used.
In Fig. 9, the induction heating power level for the right heating port 4R is shown to be "Level 6" (out of 9 levels). When the change mark 53R is displayed in this state, pressing the right shared key 42R of the pair of right shared keys 42R as shown in Fig. 9 will increase the heating power by one level to 7, and conversely, pressing the left shared key 42R once will decrease the heating power by one level to 5. Pressing it twice will increase or decrease the heating power by two levels.

The heat power display of the three heat power display sections 16L, 16M, 16R is performed by light emitting elements 16RE such as LEDs arranged in a line.
As shown in FIG. 9, the right heating power display section 16R displays the magnitude of heating power in nine stages depending on whether or not at least nine sets (18 pieces) of light emitting elements 16RE are lit and the color of the light they emit.
For example, each light emitting element is arranged in a set of two, one blue-emitting LED and one red-emitting LED, and nine sets of these are arranged in total.
Therefore, for example, a heat level of 6 is displayed by a light emitting area 55 of six light emitting elements 16RE emitting red light and a light emitting area 56 of a group (aggregate) of three light emitting elements 16RE emitting blue light. When viewed from the user, the heat level of 6 is indicated by six red light emitting elements displayed in a row. The light emitting operation of the light emitting elements 16RE is controlled by the light emitting control unit 37.

Furthermore, the left heating power display section 16L similarly emits light in two colors (red and blue), and displays the heating power in nine levels depending on whether or not nine sets (18 pieces) of light-emitting elements 16LE (not shown) emit light and the color of their light.
Furthermore, the central heating power display unit 16M displays the heating power in five stages (up to 1500 W) by the presence or absence of light from five linearly arranged light-emitting elements 16ME (five sets of five red light-emitting elements and five blue light-emitting elements) (see Figures 18 and 19) and the color of the light they emit. The light-emitting operations of the light-emitting elements 16ME and 16LE (not shown) are controlled by the light-emitting control unit 37.

Next, FIG. 10 will be described.
FIG. 10 is an explanatory diagram 2 showing the display states and input operations of the integrated display unit 15, the central operation unit (rear operation unit and front operation unit) 17, the right operation unit 18, and the right firepower display unit 16R.
10A shows the state immediately after the heating operation shown in FIG. 9 is started, and FIG. 10B shows the state immediately after the heating operation is stopped.

The stage in which induction heating is being performed at the right heating port 4R at heating power level 6 is as shown in FIG. 10(A), and the right heating power display section 16R displays "heat power 6."
At this stage, if the right ON/OFF key 41R is pressed, the drive to the right IH coil 9R is stopped and the induction heating operation is immediately stopped. If the temperature of the top plate 3 is high, for example, above 50°C, a high temperature warning message 54 is displayed in the third area 15R. The warning message remains displayed until the temperature drops below 50°C.

Next, FIG. 11 will be described.
FIG. 11 is an explanatory diagram 3 showing the display states and input operations of the integrated display unit 15, the central operation unit (rear operation unit and front operation unit) 17, the right operation unit 18, and the right firepower display unit 16R.
As shown in Figure 11 (A), the identification information (sub-cooking mode display section) 46 for "heating" is selected as the sub-cooking mode using the right shared key 42R, and then the left right shared key 42R is pressed without pressing the right ON/OFF key 41R as described in step S4 of Figure 8.
In this case, as shown in FIG. 11(B), the third area 15R displays the identification information (sub-cooking mode display section) 46 of "frying" instead of the sub-cooking mode display section 46 of "heating".
The right heating power indicator 16R is not displaying the heating power because the heating operation has not yet started. The light-emitting area 56, which is made up of a group (assembly) of nine light-emitting elements 16RE emitting blue light, indicates that the unit is in a "standby state" waiting for a heating start command.

Next, FIG. 12 will be described.
12 is an enlarged explanatory diagram showing the transition of the display operation in the right heating power display section 16R. The display operation in the left heating power display section 16L is the same.
The right heating power display unit 16R and the left heating power display unit 16L can display the heating power in up to nine stages, and can also display the progress of the preheating process in stages as shown in Figure 12. Below, the display operation of the progress of the preheating process will be explained, focusing only on the right heating power display unit 16R.

As shown in Figure 12, the progress of the preheating process can be displayed in five stages, from Preheating Process 1 to Preheating Complete. The control device 22 detects the temperature rise of the object to be heated (via the temperature sensor group 30) and determines the stage of progress, from Preheating Process 1 to Preheating Complete, based on that temperature rise.

When the preheating process begins, the right heating power display unit 16R displays the progress of the preheating process by lighting up the light-emitting element 16RE, as shown in Figure 12. The heating power of the IH coil 9R of the right heating port 4R is not displayed here. The heating power during preheating is automatically determined by the heating control unit 23.

As shown in Figure 12, in preheating stage 1, the progress of preheating is displayed by an emission area 55 formed by one light-emitting element 16RE emitting red light and an emission area 56 formed by a group of three light-emitting elements 16RE emitting blue light.
In the preheating stage 2, one light emitting element 16RE emits red light and one adjacent light emitting element emits blue light, so that a purple light emitting region 57 first appears.
This purple light emitting area 57 gradually increases in the horizontal direction to the right as the preheating progresses from preheating stage 3 to preheating stage 4. When preheating is complete, only the purple light emitting area 57 appears in a long horizontal band, indicating the completion of the preheating process.
As described above, the user can know the progress of the preheating operation by the change and size of the purple light emitting area 57.

Next, FIG. 13 will be described.
FIG. 13 is an explanatory diagram 4 showing the display states and input operations of the integrated display unit 15, the central operation unit (rear operation unit and front operation unit) 17, the right operation unit 18, and the right firepower display unit 16R.
When the right ON/OFF key 41R is operated in the state shown in Fig. 11(B) where "deep frying" is selected as the sub-cooking mode, the process proceeds to the scene where the heating operation starts, as shown in Fig. 13. The heating operation starts with the set temperature for deep frying at 180°C.
The right heating power display section 16R displays a red display area 55 and a blue display area 56.
Reference numeral 50 denotes the set temperature display section described in Fig. 7. In Fig. 13, it is shown that the set temperature is 180°C.

Next, FIG. 14 will be described.
FIG. 14 is an explanatory diagram 5 showing the display states and input operations of the integrated display unit 15, the central operation unit (rear operation unit and front operation unit) 17, the right operation unit 18, and the right firepower display unit 16R.
When "deep frying" is selected as the sub-cooking mode and heating operation has started as shown in Fig. 13, operating one of the pair of right shared keys 42R (on the right) raises the set temperature from "180°C" to "190°C," as shown in Fig. 14. In this way, after heating operation has started, the set temperature for deep frying can be set in 10°C increments within a certain range (for example, a range of 140°C to 200°C). Each time one of the pair of right shared keys 42R is operated, the set temperature can be changed by 10°C.
Even in this case, the right heating power display section 16R remains unchanged from the state shown in FIG. 13, and displays a red display area 55 and a blue display area 56.

Next, FIG. 15 will be described.
FIG. 15 is an explanatory diagram 6 showing the display states and input operations of the integrated display unit 15, the central operation unit (rear operation unit and front operation unit) 17, the right operation unit 18, and the right firepower display unit 16R.
FIG. 15 shows a scene in which the right heating port 4R is selected first and the sub-cooking mode is selected.
Even if the third area 15R displays one sub-cooking mode, "Heat," as in step S3 of FIG. 8, the mode can be changed to "Keep Warm" by pressing the right shared key 42R on the left side once. That is, as shown in FIG. 15, the third area 15R displays the "Keep Warm" identification information (sub-cooking mode display) 46 instead of the "Heat" identification information (sub-cooking mode display) 46. In this case, the display content of the right heating power display 16R remains unchanged from the state shown in FIG. 11, displaying only the blue display area 56. Therefore, it is not possible to check the heating power level on the right heating power display 16R, nor is it necessary to do so. When the sub-cooking mode is "Keep Warm," the right IH coil 9R is automatically set to a maximum heating power of, for example, 150 W.

Next, FIG. 16 will be described.
FIG. 16 is an explanatory diagram 7 showing the display states and input operations of the integrated display unit 15, the central operation unit (rear operation unit and front operation unit) 17, the right operation unit 18, and the right firepower display unit 16R.
When the right shared key 42R on the right side is pressed once while the sub-cooking mode is "Keep Warm" as shown in Fig. 15, the screen changes to an input screen where "Cancel" can be selected, as shown in Fig. 16. That is, as shown in Fig. 16, the third area 15R displays a cancel indicator 46C indicating that all sub-cooking mode settings are canceled, instead of the "Keep Warm" identification information (sub-cooking mode indicator) 46. In this case, the display content of the right heating power indicator 16R returns to the state before startup, with neither the red indicator area 55 nor the blue indicator area 56.

Next, FIG. 17 will be described.
17 is an explanatory diagram showing all the types of sub-cooking modes that can be selected using the central operation unit 15. As shown in Fig. 17, four pieces of identification information (sub-cooking mode display areas) 46 and a cancel display area 46C are displayed in the first area 15L and the third area 15R in forward and reverse order.
When the right shared key 42R of the pair of right shared keys 42R is pressed, the cooking modes can be selected sequentially in the forward direction R1 in Fig. 17. Conversely, when the left shared right key 42R of the pair of right shared keys 42R is pressed, the sub-cooking modes can be selected sequentially in the reverse direction R2 in Fig. 17. In other words, when the left shared right key 42R of the pair of right shared keys 42R is pressed, the sub-cooking mode changes from "keep warm" to "heat," and then to "fry" or "grill," and when pressed again, the cancel indicator 46C is displayed (see Fig. 16).

Next, FIG. 18 will be described.
FIG. 18 is an explanatory diagram 1 showing the display state and input operations of the integrated display unit 15 and the central operation unit (rear operation unit and front operation unit) 17 when the central heating port 4C is used.
FIG. 18(A) shows an example in which the identification information (sub-cooking mode display section) 46 for "grilled whole fish" is displayed in the center of the front-to-back direction of the second area 15M as a sub-cooking mode using the heating chamber 6.
FIG. 18(B) shows an example in which the heat source display section 47 indicating cooking using the central IH coil 9C (single cooking mode KM3) is displayed in the center of the second area 15M in the front-to-rear direction.

In the state shown in Figure 18(A), when the right-hand central shared key 42M of the pair of central shared keys 42M is pressed, the "Grilled Whole Fish" identification information (sub-cooking mode display) 46 in Figure 18(A) is changed to the display in the heat source display 47, which allows selection of the central heating port 4C. Conversely, when the left-hand central shared key 42M of the pair of central shared keys 42M is pressed, the "Fish Fillet" identification information (sub-cooking mode display) 46, which uses the heating chamber 6, can be displayed in the center of the second area 15M.

In the state shown in Figure 18(B), when the right-hand central shared key 42M of the pair of central shared keys 42M is pressed, the display in the second area 15M in Figure 18(B) changes to the display content where the "Central IH" heat source display section 47 is displayed in the center. In other words, the display changes to a state where the central IH coil 9C can be selected. Conversely, if the left-hand central shared key 42M of the pair of central shared keys 42M is pressed, the identification information (sub-cooking mode display section) 46 for "whole fish grilling," which uses the heating chamber 6, is displayed in the display position of the heat source display section 47 in Figure 18(B).

At the same time that the heating source indicator 47 for "Central IH" is displayed in the center of the second area 15M, the blue light-emitting element 16ME, one of the five linearly arranged light-emitting elements 16ME (five sets of five red light-emitting elements and five blue light-emitting elements) in the central heating power indicator 16M, lights up, indicating that the central heating port 4C is ready to begin heating. Note that when the blue light-emitting element 16ME lights up in this way, the central IH coil 9C has not yet begun actual induction heating operation.

Next, FIG. 19 will be described.
Figure 19 is an explanatory diagram showing the display state and input operation state of the integrated display unit 15 and the central heating power display unit 16M when using the central heating port 4C, and shows the state immediately after starting the heating operation in the display state of Figure 18 (B).

When the central ON/OFF switch 41M is pressed as shown in FIG. 19 in the display state of FIG. 18(B), the start of heating operation by the central IH coil 9C is confirmed. Then, the second area 15M first displays the heating power, which is one of the control conditions, as a default setting. Here, the default setting is, for example, "heat power 2," which is set to 500 W and induction heating is started. Induction heating operation is started with the heating power displayed in the heating power display unit 48.
In the central heating display unit 16, two light-emitting elements 16ME emit light to display a red display area 55, and three light-emitting elements 16ME emit light to display a blue display area 56. This allows the user to clearly recognize that the heating level is set to "heat level 2" by viewing the red display area 55.

Next, FIG. 20 will be described.
20(A) is an explanatory diagram showing the result of pressing the left central common key 42M of the pair of central common keys 42M in the display state of FIG. 18(B), showing the display state and input operation state in the integrated display section 15 and the central thermal power display section 16M.
As shown in Figure 20 (A), in place of the heat source display section 47 that was displayed in the center of the second area 15M, identification information (sub-cooking mode display section) 46 for "whole roasting" that uses the heating chamber 6 is displayed.

In the display state of Fig. 20(A), if the left central shared key 42M of the pair of central shared keys 42M is pressed once more, the state changes to that of Fig. 20(B). That is, as shown in Fig. 20(B), the identification information 46 (sub-cooking mode display) for "whole fish" displayed in the center of the second area 15M moves to a rear position, and the identification information 46 for "fillet" is displayed in the center of the second area 15M.
20(A) and 20(B), cooking using the heating chamber 6 cannot be selected at the same time as cooking using the central heating port 4C. In other words, cooking using the heating chamber 6 and cooking using the central heating port 4C are mutually exclusive, and only one of them can be selected.

Next, FIG. 21 will be described.
21(A) is an explanatory diagram showing the input operation for starting the heating operation in the sub-cooking mode using the heating chamber 6. Specifically, it is a schematic diagram showing the change in the display operation of the auxiliary display unit 60 that appears in the second area 15M at appropriate timing.
The auxiliary display section 60 displays the level of heat and the set temperature after the heating operation has started.
As shown in Figure 21 (A), the magnitude of the heating power in the heating chamber 6 is displayed in the form of a five-level bar graph. As the position of the red display section 61 moves to the right, the heating power value increases in order from heating power 1 to heating power 5. Note that the heating power here refers to the driving conditions of the upper radiant heat heating means 12a and the lower radiant heat heating means 12b. In other words, it refers to the heating capacity of the third heating means HM3, and does not indicate the microwave output of the microwave heating means 11 (second heating means HM2).
The higher the set temperature, the more the red display section 61 is displayed to the right, indicating that the temperature is set to a higher value.

FIG. 21(B) shows a scene in which cooking of "fillets" is started as a sub-cooking mode using heating chamber 6.
In the state shown in FIG. 20(B), when the central ON/OFF switch 41M is pressed as shown in FIG. 21(B), the heating operation by the third heating means HM3 of the heating chamber 6 is confirmed.
As shown in FIG. 21(B), the display in the second area 15M displays a sub-cooking mode display section (identification information) 46 at the rear to indicate the sub-cooking mode of "fillet."
Reference numeral 53M denotes a change mark similar to the change mark 53R (see FIG. 13), and indicates that the control conditions for cooking in the second area 15M can be changed.

As shown in Figure 21 (B), when cooking in one sub-cooking mode is confirmed, heating intensity information 62 indicates the heating conditions of that sub-cooking mode in specific terms. In the "fillet" sub-cooking mode shown in Figure 21 (B), there are, for example, five types of heating intensity information, and the following displays are used in order of decreasing heating intensity: "weak," "slightly weak," "standard," "slightly strong," and "strong." However, other types of heating intensity information may also be used, such as three or six or more types. For example, when there are three types of heating intensity, the displays "weak," "standard," and "strong" may be used.

FIG. 22 is an explanatory diagram showing the operation of inputting heat power in one sub-cooking mode (fillet) using the heating chamber 6.
21(B), the heating intensity is "standard," so it is still possible to increase or decrease the heating intensity. Therefore, the change mark 53M is displayed on both the left and right sides of the heating intensity information 62.
An example of a case where the user further increases the heating intensity from the "standard" heating intensity shown in Fig. 21(B) is shown in Fig. 22. By pressing the right central shared key 42M of the pair of central shared keys 42M as shown in Fig. 22, the heating intensity information 62 can be changed from "standard" to "strong."
In the state of FIG. 22, it is not possible to further increase the heating intensity, so the deformation mark 53M is displayed only to the left of the heating intensity information 62.

Referring to Figure 23, in the "fillet" sub-cooking mode shown in Figure 20(B), pressing the right central shared key 42M once will change "fillet" to "grill." Furthermore, pressing the right central shared key 42M once will change "grill" to "oven." In the state shown in Figure 23(A), pressing the central on/off switch 41M confirms the heating operation in the oven sub-cooking mode by the third heating means HM3 in the heating chamber 6.
As shown in FIG. 23(B), the display in the second area 15M displays the heat source display section 47 at the rear to indicate the sub-cooking mode "oven."

Reference numeral 50 denotes a set temperature display section. One example of this set temperature display section 50 indicates that the target heating temperature for the oven preheating step set by the user is "180°C."
That is, in this state 23(B), it can be seen that the "oven" cooking mode is being performed at 180°C. The heating chamber 6 is heated in one go by the third heating control means HM3 using the heating control unit 23 (see FIG. 5) and the temperature sensor group 30 until the atmospheric temperature inside the heating chamber 6 reaches 180°C. When 180°C is reached, preheating is complete. When preheating is complete, a notification is given by the audio notification unit 49 of the notification means 40 or the integrated display unit 15. Then, in order to maintain the set temperature (e.g., 180°C), the heating control unit 23 automatically controls the power supply to the third heating control means HM3 for a certain period of time.

Referring to Figure 24, in the sub-cooking mode shown in Figure 24(B), pressing the left central shared key 42M once will lower the set temperature (180°C). Each time the central shared key 42M is pressed, the temperature will be lowered by 10°C. Figure 24(A) shows the temperature being changed to 170°C in this manner. In both Figures 23(B) and 24, the change mark 53M is displayed on both the left and right sides of the set temperature display unit 50, so the set temperature can be either increased or decreased.

FIG. 25 will be explained. FIG. 25 is an explanatory diagram showing all the types of sub-cooking modes using the heating chamber 6 that can be selected by the central operation unit 17 of the cooking appliance 1.
As is clear from Fig. 25, there are five sub-cooking modes in total: "Central IH,""WholeGrill,""Fillet,""Grill," and "Oven." The sub-cooking mode display 46 is displayed in the second area 15M so that these five sub-cooking modes can be identified.
Also, as shown in Figure 25, one cancellation display section 46C, the sub-cooking mode display section 46 and the heating source display section 47 are displayed sequentially within the range of the second area 15M in the order of forward direction R1 and reverse direction R2.

Next, FIG. 26 will be described.
FIG. 26 is a flowchart 1 showing the operation of the cooking appliance 1 at startup.
8, when the operation button (key) 20A of the main power switch 20 located at the right end of the right operation unit 18 is first pressed and held down (for a certain period of time or longer), the main power switch 20 is closed and commercial power is applied to the power circuit 27. When the power circuit 27 is in the ON state, pressing and holding the operation button 20A again, for example, for several seconds, turns the power circuit 27 OFF.

The operation shown in FIG. 26 is defined in the basic operation program of the control device 22.
First, when the operation button 20A of the main power switch 20 is pressed (ST1), commercial power is applied to the power circuit 27.
In the next step ST2, the heating control unit 23 determines whether or not there is an abnormality (hereinafter referred to as "initial self-check"). Also, if the setting at step ST2 is such that start-up information is transmitted from the cooking appliance 1 to the communication terminal 200 or the cloud server 300, the start-up information (operating state data) is transmitted wirelessly from the communication unit 25 at this stage. Note that if an abnormality is detected as a result of the initial self-check, information on the abnormality detection may be included in the start-up information and transmitted to the outside.

In the next step ST3, if no abnormalities are found as a result of the initial self-check, the integrated display unit 15 is activated. On the integrated display unit 15, all display screens from the first area 15L to the third area 15R are activated simultaneously, and the display screens from the first area 15L to the third area 15R become the "initial standby screen." The initial standby screen here refers to a guidance screen that displays information such as "Cooking can begin" and "Precautions for use." This information may be displayed individually in the first area 15L to the third area 15R, or the three display areas may be combined into one larger display area to display precautions, etc. At this stage, the heating control unit 23 also checks whether a setting command has been received from the input operation unit 36 regarding the upper limit of the total power consumption of the cooking appliance 1.

At step ST3, the audio notification unit 22 also provides notification and audio guidance to prompt the user to select the heating means.
In the next step ST4, the integrated display unit 15 displays a message prompting the user to perform an input operation. That is, information (hereinafter referred to as "initial input recommendation information") is displayed, prompting the user to select a heating means to be used and a cooking mode (e.g., the single cooking mode KM3). Note that, in the step following the display of the initial input recommendation information, the sub-cooking mode display unit 46 indicating "Keep Warm" may be displayed as the default cooking mode display in all of the first area 15L to the third area 15R, as shown in FIG. 8 . Alternatively, the heating source display unit 47 indicating "Central IH" may be displayed in the second area 15M.

Then, it is checked whether any of the three pairs of input keys arranged on the rear operation unit 17B have been operated. That is, it is determined whether any of the left shared key 42L, center shared key 42M, or right shared key 42R has been operated (ST5). For example, as in step S2 described in Figure 8, if the right shared key 42R has been operated, step ST5 will be "Yes" and the process will proceed to step ST6.

In step ST5, the most recent input operation is checked. For example, it is determined whether the left shared key 42L or the center shared key 42M was operated before the right on/off switch 41R was pressed after the right shared key 42R was pressed. The selection of the three heating means HM1 to HM3 is confirmed when the three on/off switches 41L, 41M, and 41R are pressed. Therefore, if any of the three pairs of shared keys 42L, 42M, and 42R are pressed before this confirmation, the heating means corresponding to that shared key can be selected.

In step ST6, the permission condition determination unit 26 checks whether the "permission conditions" are met. For example, it checks the usage status of the heat source used in the "cooperative cooking mode" KM1. For example, if the right IH coil 9R of the right heating port 4R is already in heating operation for another cooking, the permission condition is determined to be "unusable," i.e., the result is "No."
In the case of FIG. 26, since the main power switch 20 has just been turned on, it is impossible that the appliance has already been used for another cooking operation, and therefore the answer is "available," i.e., "Yes."

In FIG. 26, step ST6 is a stage for determining "permission condition 1."
Here, "Permission Condition 1" means:
(1) The "peak cut value" that specifies the upper limit of the maximum power that can be used by the cooking appliance 1 is 5000 W or more.
(2) When a power reduction command signal is received by the control device 22 via the communication unit 25 from the external cloud server 300 or the communication terminal 200, the peak cut value of the reduction command is 5000 W or more;
If these two conditions are met, the determination in step ST6 is "Yes."

The "permission condition 2" in the next step ST7 is the following four conditions.
(1) In the first heating means HM1, the central heating port 4C is not in heating operation.
(2) Either the second heating means HM2 or the third heating means HM3 or both of them are not in heating operation.

(3) In the first heating means HM1, neither the right heating port 4R nor the left heating port 4L is being used for heating (or only one of them is in heating operation). In other words, neither the left IH coil 9L nor the right IH coil 9R is being used for heating.
(4) The latest temperatures of the top plate 3 and the heating chamber 6 are not so high as to exceed a limit value (for example, 50° C.).

If the above four conditions are met, step ST7 will result in a "Yes" judgment. Then, the process will proceed to step ST9. In other words, as explained in step S4 of Figure 8, the selection of the three heating ports and heating chamber 6 is confirmed, and the process can proceed to the step of starting cooking. That is, in step ST9, for example, as explained in Figure 9, the process can proceed to the induction heating cooking process using the right heating port 4R, and the control conditions such as heat power (heat power display section 48) will be displayed in the first area 15R.

If the judgment in steps ST6 and ST7 is "No," proceed to step ST8, where the integrated display unit 15 and/or the audio notification unit 22 notify the user that the selected cooking mode cannot be selected. The user is then prompted to select a different heating method or main cooking mode. For example, the user is notified that the permission conditions are not met unless the cooperative cooking mode KM1 is changed to the independent cooking mode KM3.

In this embodiment 1, the combined cooking mode KM2 selectable by the central operation unit 17M exceptionally includes sub-cooking modes such as "cook rice" and "keep warm" as cooking menus for the single cooking mode KM3 using the central IH coil 9C. For example, if the heating source display 47 for "central IH" described in FIG. 25 is selected, the identification information 46 for the sub-cooking modes "cook rice" and "keep warm" are displayed sequentially (one by one) immediately afterwards.

When the door 7 of the heating chamber 6 is opened after the main power switch 20 is turned "ON", the control device 22 detects that the door 7 has been opened.
It is assumed that the user will be cooking using the heating chamber 6, and the initial standby screen has a function to automatically display identification information (sub-cooking mode display section) 46 and a heating source display section 47 in the second area 15M, as shown in Figures 18 to 24.
In other words, immediately after the main power switch 20 is turned "ON," the display screen of the integrated display unit 15 displays the above-mentioned "standby initial screen." After that, immediately after the door 7 is opened, the sub-cooking mode display unit 46 and the heat source display unit 47 are automatically displayed only in the second area 15M, even if one of the pair (two) shared keys 42M on the rear operation unit 17B is not operated.

When both the left IH coil 9L of the left heating port 4L and the right IH coil 9R of the right heating port 4R are being used for cooking, the display screen of the integrated display unit 15 displays identification information (sub-cooking mode display unit) 46, set temperature display unit 50, heat power display unit 48, etc. in both the first area 15L and the third area 15R.
In the first to third areas 15L to 15R, after the heating operation is completed, the high temperature warning display information 54 as described with reference to FIG. 10(B) is automatically displayed.

Next, FIG. 27 will be described.
FIG. 27 is an explanatory diagram showing an overview of all the types of the combined cooking mode KM1 and the cooking steps of the cooking appliance 1.
As is clear from FIG. 27, there are a total of eight (linked) cooking menus, and eight pieces of identification information 72 (identification information Z) are displayed in order in the central area 15M.
When the right central shared key 42M of the pair of central shared keys 42M is pressed, the identification information 72 of the eight linked cooking menus is displayed one by one in the forward (R1) direction in the center of the central display section 15M.
Conversely, when the left central shared key 42M of the pair of central shared keys 42M is pressed, the items are displayed one by one in the forward (R1) and reverse (R2) directions in the center of the front-to-back direction of the central display unit 15M. Note that, although "hamburger" is displayed as a default setting, this may be changed in advance using the function setting key 45 so that the identification information 72 of another cooking menu (for example, "fried chicken") is displayed with first priority. Note that the identification information 72 may be referred to as "identification information Z" to avoid confusion with the identification information 46.

Next, FIG. 28 will be described.
FIG. 28 is a flowchart showing the operation of the control device 22 when the combined cooking mode KM1 is executed in the cooking appliance 1.
The operations shown in steps SA1 to SA12 are defined in the basic operation program of the control device 22.

For the sake of simplicity, the description will begin with step SA1, which corresponds to step ST4 described with reference to FIG.
In step SA1, a display is displayed to prompt the user to perform an input operation, i.e., the initial input recommendation information is displayed, which prompts the user to select the heating means to be used and the cooking mode.
Next, when the user presses the selection key 70 for selecting the collaborative cooking mode provided on the right operation unit 18, the collaborative cooking menus (stored in the memory device 41) as described in Figure 27 are called up one by one and displayed in the central area 15M (step SA2).

When the right shared central key 42M of the pair of shared central keys 42M is pressed (step SA3), the central display section 15M displays one identification information (cooking menu candidate display section) 72A from the collaborative cooking menu shown in FIG. 27 in a forward (R1) order. Pressing the right shared central key 42M once more changes the order in the forward (R1) order, changing the display content so that the identification information (cooking menu display section) 72 is displayed in the center of the front-to-back direction of the central area 15M (step SA4).

The integrated display unit 15 and the voice notification unit 49 display and voice guide the user to operate the corresponding ON/OFF keys 41L, 41M, 41R to start cooking in the cooperative cooking mode KM1.
If there is an objection to the content of one piece of identification information (cooking menu display section) 72 displayed in the center of the front-to-back direction of the central area 15M, the right or left central shared key 42M of the pair of central shared keys 42M is operated, and the process returns to step SA3 (step SA5).
If step SA4 is judged "Yes," the process proceeds to step SA6, where the ON/OFF key 41L, 41M, or 41R corresponding to one of the first to third areas 15L to 15R is pressed (step SA6). This then initiates the heating operation (step SA7). If step SA6 is left in this state for a certain period of time (e.g., 30 minutes), a warning message is displayed on the integrated display unit 15 for safety reasons, and then the control device 22 automatically opens the main power switch 20.

On the other hand, if, in step SA2, the selection key 70 is not pressed but one of the three pairs of shared switches 42L-42R is pressed (step SA8), a cooking mode other than the cooperative cooking mode KM1 is selected. Then, the integrated display unit 15 displays the identification information 46 of one sub-cooking mode according to the operated shared switch 42L-42R (step SA9). For example, as described in Figure 11 (A), the identification information (sub-cooking mode display unit) 46 for performing "induction heating" on the right heating port 4R is displayed.

Next, in step SA10, if the right shared key 42R is not pressed but the right ON/OFF key 41R is pressed (step SA11), heating operation using the right IH coil 9R begins (step SA12). If the right shared key 42R is pressed in step SA10, the process returns to step SA9, and another piece of identification information (sub-cooking mode display) 46 is displayed in the center of the left area (third area) 15R in the front-to-back direction. Note that in step SA8, the right shared switch 42R of the three pairs of shared switches 42L-42R was pressed, but the left shared switch 42L or the center shared switch 42M may also be pressed.

Next, FIG. 29 will be described.
FIG. 29(A) shows a scene where the user first operates the selection key 70 when cooking in the cooperative cooking mode KM1.
29(B) shows the state in which the identification information (cooking menu display section) 72 for "hamburger" is displayed as one of the cooking menus in the cooperative cooking mode KM1. The identification information (cooking menu candidate display section) 72A for "paella" and "tempura" are displayed in slightly smaller letters before and after the identification information 72.

71L is a heating unit selection indicator displayed in the left area (first area) 15L. In the example of the collaborative cooking menu (hamburger) shown in Figure 29 (B), the function setting key 45 has been set in advance so that it can be performed using only the left heating port 4L. Therefore, for the cooking menu "hamburger," the heating unit selection indicator 71L is displayed only in the first area 15L, as shown in Figure 29 (B). However, depending on the cooking menu in collaborative cooking mode KM1, the heating unit selection indicator 71R may be displayed in the right area (third area) 15R. Furthermore, when identification information 72 is displayed in the central area (second area) 15M, the heating unit selection indicator 71M is generally not displayed in the same central area 15M, but this may be changed to display it.

Next, FIG. 30 will be described.
Figure 30 is an explanatory diagram 2 showing the display state and input operations of the integrated display unit 15, central operation unit (rear operation unit/front operation unit) 17, right operation unit 18 and right heat output display unit 16R when cooking in the collaborative cooking mode KM1.

FIG. 30 shows a continuation of the input operations in the scene of FIG. 29(B), but the central operation unit 17 has been slightly improved to emphasize to the user the left-cut key 41L that should be operated last.
In the state of Fig. 29(B), if "Hamburger" is not selected and the left central shared key 42M of the pair of central shared keys 42M is pressed, the identification information (cooking menu display section) 72 for "Paella" is displayed in the center of the central area (second area) 15M as shown in Fig. 30. Also, a heating section selection instruction section 71L is displayed in the left area (first area) 15L.
Furthermore, as shown in Figure 30, the left cut-in key 41L corresponding to the left area (first area) 15L is illuminated from below by a light-emitting element (shown) under the light-emitting control unit 37 (see Figure 5), displaying a figure in, for example, blue or yellow, and emphasizing the operating portion of the left cut-in key 41L.

Next, FIG. 31 will be described.
Figure 31 is an explanatory diagram 3 showing the display state and input operations of the integrated display unit 15, central operation unit (rear operation unit/front operation unit) 17, right operation unit 18 and right heat output display unit 16R when cooking in the collaborative cooking mode KM1.
Fig. 31 shows a continuation of the operation in Fig. 29(B), but shows a different configuration from Fig. 30. That is, in Fig. 30, one linked cooking menu (hamburger steak) was set in advance with the function setting key 45 so that it could be performed using only the left heating port 4L, and therefore the left cut-on key 41L, which should be operated last, was shown to the user by the heating unit selection indicator 71L in the first area 15L.

In contrast, Figure 31 shows an example in which one linked cooking menu, "paella," is not set in advance using the function setting key 45 so that it can be executed using only the left heating outlet 4L, but is instead set to the default state, so that it can be executed using either the left or right heating outlet 4L or 4R.
In FIG. 31 , 73L is a left heater selection guide indicating that cooking of an integrated cooking menu (in this case, "paella") can be started using the left IH coil 9L. 73R is a right heater selection guide indicating that cooking of an integrated cooking menu (in this case, "paella") can be started using the right IH coil 9R. In FIG. 31 , the left and right heater selection guides 41L and 41R, respectively, are illuminated from below by light-emitting elements (shown) from the light-emitting control unit 37 (see FIG. 5 ) to prompt operation. In this case, both the left and right heater selection keys 41L and 41R cannot be operated simultaneously. Only the key operated first is recognized as a valid signal by the control device 22.

Next, we will explain Figure 32.
Figure 32 is an explanatory diagram 4 showing the display state and input operations of the integrated display unit 15, central operation unit (rear operation unit/front operation unit) 17, right operation unit 18 and right heat output display unit 16R when cooking in the collaborative cooking mode KM1.
Figure 32 shows an example in which the configuration shown in Figure 30 has been slightly modified. In Figure 32, the collaborative cooking menu (paella) is set in advance using the function setting key 45 so that it can be performed using only the left heating port 4L. To clearly display the left power-on key 41L, which should be operated last, a heating unit reception instruction section 74L is displayed in the first area 15L. This heating unit reception instruction section 74L guides the user to operate the left power-on key 41L.

Next, we will explain Figure 33.
Figure 33 is an explanatory diagram 5 showing the display state and input operations of the integrated display unit 15, central operation unit (rear operation unit/front operation unit) 17, right operation unit 18 and right heat power display unit 16R when cooking in the collaborative cooking mode KM1.
FIG. 33 shows an example of a collaborative cooking menu in which cooking step 1 is performed in the heating chamber 6, specifically, "fried chicken." In other words, in FIG. 33, the collaborative cooking menu (fried chicken) requires a "preheating" operation in the right heating port 4R, as shown in FIG. 27, but cooking step 1 is performed by microwave heating in the heating chamber 6 (microwave heating). Therefore, the center ON/OFF key 41M must be operated to select the second heating means HM2, which is the heating means for cooking step 1. In the example of FIG. 33, the heating unit selection indicator 71R is displayed in the right area (third area) 15R. After cooking of this "fried chicken" begins, preheating of the object to be heated, such as a frying pan, placed on the right heating port 4R is initiated by driving the right IH coil 9R. Concurrently, the door 7 in the heating chamber 6 is opened, and cooking step 1 in the heating chamber 6 is performed by microwave heating only when the control device 22 detects that the door 7 has been closed again. In other words, the preheating operation at the right heating port 4R and the cooking process 1 in the heating chamber 6 are carried out in the same time period.

Furthermore, in the cooking device 1 of the first embodiment,
The rear operation unit 17B further includes a central shared switch (key) 42M disposed in front of the central area 15M.
The front operating section 17F is characterized by the fact that a central on/off key 41M for selecting the central heating port 4C (central IH coil 9C) is located further forward than the central shared switch (key) 42M.

This configuration results in a cooker 1 equipped with three heating ports 4L, 4C, and 4R, which increases the number of heated objects (such as pots) that can be used simultaneously, improving usability. It also allows the user to correctly recognize the correspondence between the three (left, center, and right) heating ports 4L, 4C, and 4R to be selected and the various input switches (left shared switch 41L, center shared switch 41M, right shared switch 41R, left on/off switch 42L, center on/off switch 42M, and right on/off switch 42R) used to input sub-cooking modes and control conditions (heat output, set temperature, etc.), which is expected to prevent operational errors. This also contributes to the realization of a cooker 1 that is easy to use.

Furthermore, in this first embodiment, the cooking device 1 according to the second disclosure is disclosed as follows.
That is, one embodiment of the cooking device 1 according to the second disclosure is as follows:
a first heating means HM1 for performing a heating operation at the left heating port 4L and the right heating port 4R, which are respectively arranged on the top surface of the main body;

Step SA6 accepts an input operation of a power-on/power-off key 41L, 41M, or 41R located in front of any one of the left area 15L, the right area 15R, or the central area 15M, which corresponds to any one of the left heating port 4L, the right heating port 4R, or the second heating means HM2 that can execute the cooking step 1 of the cooperative cooking menu;
The configuration is characterized by sequentially executing the above.

This configuration allows for the provision of a cooking appliance 1 that can accommodate a wide variety of cooking methods using multiple heating ports, contributing to more efficient input operations and reduced input load for users.

Furthermore, according to the heating cooker 1 of the second disclosure described above, the selection of at least the left and right heating ports 4L, 4R and the selection of the linked cooking mode KM1 can be performed in a concentrated manner in the front of the left area (first area) 15L and the right area (third area) 15R of the integrated display unit 15, with one integrated display unit 15 at the center.
Therefore, the user can select a cooking menu for the linked cooking mode by operating the shared switches (keys) 42L, 42R located in front of the left area 15L or right area 15R of the integrated display unit 15, and then decide to start the heating operation using the left on/off switch 42L, the right on/off switch 42R, or the center on/off switch 42M. Therefore, the selection of a cooking menu for the linked cooking mode and the selection of the heating ports 4L, 4R located on the left and right can be efficiently performed using the three shared switches 42L, 42M, 42R located in front of one integrated display unit 15 and the on/off switches 41L, 41M, 41R.
As a result, a user-friendly cooking appliance 1 can be provided.

Furthermore, the cooking device 1 according to the second disclosure includes:
In a cooking mode other than the cooperative cooking mode KM1,
The control device 22
Step S1: displaying identification information 46(X) of one sub-cooking mode from among a plurality of sub-cooking modes in either the left area 15L or the right area 15R;
Step S2: accepting an operation of either the left shared key 42L corresponding to the left area 15L or the right shared key 42R corresponding to the right area 15R;
In response to the operation of step S2, step S3 displays identification information 46A(Y) different from the identification information 46(X);
After step S3, step S4 accepts the operation of the left ON/OFF key 41L to select the left heating port 4L corresponding to either the left shared key 42L or the right shared key 42R operated in step S2, or the right ON/OFF key 41R to select the right heating port 4R.
Step S5: Starting a heating operation with a default heating power setting;
Step S6: changing the heating power started in step S5 to another heating power in response to an operation of the left shared key 42L or the right shared key 42R;
The configuration was characterized by sequentially executing the above.

This configuration makes it possible to provide a cooking appliance 1 that can accommodate a wide variety of cooking methods, improves the efficiency of user input operations, and reduces the input burden, particularly regarding heat setting.

Furthermore, according to the heating cooker 1 configured as in the above-described embodiment 1, the selection of at least the left and right heating ports 4L, 4R and the selection of the heating cooking in the heating chamber 6 can be concentrated in front of the left area (first area) 15L, right area (third area) 15R, and central area (second area) 15M of the integrated display unit 15, with one integrated display unit 15 at the center.
Therefore, the user can select the sub-cooking mode by operating the shared switches (keys) 42L and 42M located in front of the integrated display unit 15, and then decide to start the heating operation by using the left turn-on key 41L or the right turn-on key 41R.

As described above, the sub-cooking mode can be selected, the heating ports 4L and 4R spaced apart to the left and right can be selected, cooking in the heating chamber 6 can be selected, and the heat level can be set (changing from the default setting) efficiently using the shared switches (keys) 42L, 42M, and 42R and the on/off keys 41L and 42R located in front of the single integrated display unit 15. This makes it possible to provide a cooking appliance 1 that is easy for users to use.

Furthermore, the cooking device 1 of the first embodiment has various characteristic configurations as described below, and specific effects can be expected according to these configurations, as will be described below.
6, the right heating power display unit 16R is located immediately to the right of the integrated display unit 15. The right operating unit 18 is located a short distance to the right of the front operating unit 17F, along a horizontal reference line BL that crosses the front edge of the front operating unit 17F.
The right operation section 18 has a timer switch 43, a setting key 44 for changing the set time of the timer switch 43, and an input key 29 for setting the voice input mode, which are arranged in a straight line in the right horizontal direction.

With this configuration, whether cooking with the left heating port 4L, the central heating port 4C, the right heating port 4R, or the heating chamber 6, the user can efficiently perform various operations, such as managing the heating time of the timer function or switching to voice input mode, using the right operating unit 18 located next to the central operating unit 17. In other words, the central operating unit 17 and the right operating unit 18 allow for "concentrated" setting of heating and cooking conditions for a total of four locations: the left heating port 4L, the central heating port 4C, the right heating port 4R, and the heating chamber 6. Note that "concentrated" here means that the user does not need to stretch their arms out to the left or right to perform input operations, but can accurately perform input operations within a relatively narrow range, as can be seen in Figure 6.

Embodiment 2.
FIG. 34 is an explanatory diagram 1 showing the display state and input operation of the integrated display unit 15 and central operation unit (rear operation unit and front operation unit) 17 of the cooking appliance 1 showing the second embodiment. FIG. 35 is an explanatory diagram 2 showing the display state and input operation of the integrated display unit 15 and central operation unit (rear operation unit and front operation unit) 17 of the cooking appliance 1 showing the second embodiment. FIG. 36 is a flowchart showing the operation of acquiring recipe data CD from an external device in the cooking appliance 1 shown in FIG. 34. FIG. 37 is a flowchart showing the operation of acquiring recipe data for the linked cooking mode from an external device in the cooking appliance 1 shown in FIG. 34. FIG. 38 is an explanatory diagram 3 showing the display state and input operation of the integrated display unit and central operation unit (rear operation unit and front operation unit) of the cooking appliance 1 showing the second embodiment. Note that parts that are the same as or equivalent to the configuration of the first embodiment described in FIGS. 1 to 33 are assigned the same reference numerals.

In the second embodiment, the configurations of the integrated display unit 15 and the central operation unit 17 of the cooking appliance 1 are different from those in the first embodiment.
That is, in this embodiment 2, the display screen of the integrated display unit 15 is configured as a touch input panel, and the integrated display unit 15 is provided with touch input type (three pairs of) common keys 42L, 42M, 42R, which is a major difference from embodiment 1.

Referring to FIG. 34 .
The integrated display unit 15 is configured with a touch panel in which the entire display screen or at least the front half of the display screen serves as a touch panel input means.
As in embodiment 1, the display screen of the integrated display unit 15 has a left display area (left area) 15L, a central display area (central area) 15M, and a right display area (right area) 15R, which are arranged adjacent to each other in the left-right direction.

The left area 15L is composed of two parts: a rear area 63B and a front area 63F adjacent to the rear area 63B. However, the rear area 63B and the front area 63F are not formed separately in hardware. At least the front area 63F has the function of accepting touch operations performed by the user. In this embodiment 2, the left shared key 42L in embodiment 1 is configured in the form of an icon that detects touches by the user's fingertip FG. In other words, when the user's fingertip touches either of the pair of left shared keys 42L, the touch operation is detected and information can be input.

(Valid) touch input in the front area 63F is limited to touching the left shared key 42L; touching a position outside the left shared key 42L or touching the rear area 63B will not generate any valid input signal. Furthermore, tapping, which is the operation of lightly tapping the surface of the front area 63F other than the left shared key 42, as well as various touch gesture operations such as flicking, which is the operation of flicking the finger on the surface, and swiping, which is the operation of tracing the surface with a finger (sliding the finger), are not valid operations, and input using such operations is not possible.

The central area 15M, which is used for cooking using the central heating port 4C and heating chamber 6, is also composed of two parts: a rear area 64B and a front area 64F adjacent to this rear area 64B. Like the left area 16L, the pair of central shared keys 42M are configured in the form of icons that detect touches with the user's fingertips FG. Furthermore, the right area 15R is also composed of two parts: a rear area 65B and a front area 65F adjacent to this rear area 65B. Like the left area 16L, the pair of right shared keys 42R are configured in the form of icons that detect touches with the user's fingertips FG.

Reference numeral 67 denotes a set time display section, which displays the set time in units of one second when the cooking time is set using the timer switch 43.
Reference numeral 75 denotes a recipe data acquisition key (switch), which has the function of permitting the acquisition of recipe data CD (CD1, CD2) from the outside via the communication unit 25 (see FIG. 5). That is, in the first embodiment, the three common keys 42L, 42M, and 42R were the switches (keys) that needed to be operated before acquiring recipe data CD each time, depending on the type of cooking menu. In contrast, in the second embodiment, when acquiring recipe data CD from the outside, the method is unified to operating the recipe data acquisition key 75 in advance.

The recipe data acquisition key 75 is located at the left end of the right operation unit 18, close to the right end of the front operation unit 17F. When the control device 22 receives preview information for recipe data CD from the outside, the surface of this recipe data acquisition key (switch) 75 itself is illuminated from below (by a light-emitting element such as an LED) to indicate that it is operable. The light-emitting element is controlled by the light-emission control unit 37.

Next, we will explain Figure 35.
Figure 35 is an explanatory diagram showing the display state and input operations of the integrated display unit 15 and central operation unit (rear operation unit/front operation unit) 17 when cooking is actually being performed in the heating cooker 1 shown in Figure 34.

The example shown in Figure 35 shows the intermediate stage of cooking using the left heating port 4L and the right heating port 4R. Note that Figure 35 shows a state in which the cooking menu of the combined cooking mode KM1 is not being prepared for or is not being performed.
Reference numeral 66 denotes a remaining time display section, which displays the elapsed time from the start of cooking in units of one second when the cooking time is set using the timer switch 43. From the contents displayed in this remaining time display section 66, it can be seen that in the example of Fig. 35, cooking will be completed in seven minutes.
As is clear from Fig. 35, when the left heating port 4L is in heating operation, the left ON/OFF switch (key) 41L is illuminated from below by a light-emitting element (not shown) such as an LED to indicate that the switch is in operation. For example, the left ON/OFF switch (key) 41L is illuminated with a yellow light to enhance its presence. In this case, the light-emitting element is controlled by the light-emitting control unit 37 (see Fig. 5).

Similarly, since the right heating port 4R is in heating mode, the right ON/OFF switch (key) 41R is illuminated from below by a light-emitting element (not shown), such as an LED, to indicate that it is in operation. For example, it may be illuminated with a yellow light to enhance the presence of the right ON/OFF switch (key) 41R. In this case, the light-emitting element's light-emitting operation is controlled by the light-emitting control unit 37 (see Figure 5).

Furthermore, for the left shared switch (key) 42L and the right shared switch (key) 42R, during the period when input of control conditions such as heat output and temperature is possible, as can be seen in Figure 35, the icon portion to be touched is made different from the scene in Figure 34. Alternatively, the displayed color is changed. This makes it clear when input is possible and when it is not possible. Such changes in display design are executed by the control program of the integrated display unit 15 itself upon receiving a heating operation status signal from the control device 22.

Next, FIG. 36 will be described.
In this Figure 36, steps SS1 to SS8 are operation steps when acquiring recipe data CD (from outside) for two cooking modes KM2 and KM3 other than the ``cooperative cooking mode KM1'' specified in the integrated control program of the control device 22.

First, when the operation button 20A of the main power switch 20 is pressed, the input function of the input operation unit 36 is enabled in the next step SS1.
Next, the integrated display unit 15 is activated, and the initial standby screen is displayed in each of the left area (first area) 15L to the right area (third area) 15R (step SS2).

The cooking appliance 1 may prompt the user for prior confirmation as to whether to transmit a signal requesting the provision of cooking recipe data CD to the pre-registered communication terminal 200 or cloud server 300. However, if such automatic external connection is performed in advance using the function setting key 45 of the input operation unit 36, the connection operation will be performed automatically at a specified timing. In other words, the smartphone 200 and cooking appliance 1 can be automatically paired, and wireless communication 330 can be established between the smartphone 200 and cooking appliance 1 (step SS3). The audio notification unit 49 may also provide an audio notification that it is OK to perform an operation to obtain recipe data CD from an external device (step SS3).

The external connection in step SS3 involves alternately repeating transmission and reception several times between the cooking appliance 1 and the external communication device (such as the communication terminal 200 or the cloud server 300).
For example, before the communication terminal 200 first transmits recipe data CD for a specific cooking menu (in the single cooking mode KM3 or the combined cooking mode KM2), it transmits a notice signal (notice information) for identifying the cooking menu to the cooking appliance 1. The cooking appliance 1 then analyzes this notice signal, and if it is confirmed that the notice signal is the desired recipe data CD, it displays a message on the integrated display unit 15 prompting the user to perform a recipe acquisition operation.

When recipe data acquisition key (switch) 75 is operated on cooker 1, cooker 1 transmits "recipe selection information" indicating that a specific cooking menu (in this case, "frozen dumplings") has been selected via communication unit 25 (step SS5). This "recipe selection information" is then recognized by communication terminal 200 or cloud server 300.
The communication terminal 200 receives the "recipe selection information" and transmits recipe data CD. Upon receiving this transmitted data, the cooking appliance 1 checks the internal state (for example, the set value of the total power consumption, etc.), and if there are no problems, transmits a standby signal 2 to proceed to the next step (step SS6).

Finally, the necessary "setting information" (including recipe data CD) is received from the external communication device (such as communication terminal 200). In other words, the cooking appliance 1 receives a signal once, then immediately returns another confirmation signal, and so on, repeating alternating communications several times until the necessary "setting information" is finally received (step SS7).

In the next step SS8, the contents of the recipe data CD acquired from an external device such as the communication terminal 200, particularly the unique information 46 of one cooking menu item (e.g., "frozen dumplings") within the range of combined cooking mode KM2 or single cooking mode KM3, are displayed on the integrated display unit 15. Furthermore, the audio notification unit 49 notifies the user of the fact that the recipe has been received, for example, by saying, "A recipe for frozen dumplings has been received."

As is clear from the above description, the control device 22
(1) a communication establishment step (SS3) of establishing a communication state with a specific communication terminal 200;
(2) after the communication establishment step (SS3), a notification step (SS4) of notifying the notification means 40 of information indicating that the recipe data acquisition key (switch) 75 needs to be operated in accordance with advance notice information acquired from the communication unit 25;
(3) A confirmation step (SS5) of transmitting “recipe selection information” when the recipe data acquisition key (switch) 75 notified by the notifying means 40 is operated;
(4) a reception standby step (SS6) for preparing to receive the recipe data CD after transmitting the "recipe selection information";
The above steps are executed sequentially.

In addition, in the reception standby step (SS6), a check is made to see if "Permission Condition 2" described in Figure 26 of Embodiment 1 is met. For example, a check is made to see if the latest temperatures of the top plate 3 and heating chamber 6 are not so high as to exceed a limit value (e.g., 50°C). This ensures that when using the heating chamber 6 to thaw and heat an item to be cooked (e.g., frozen food such as frozen dumplings) using microwave heating, cooking begins in a state that does not adversely affect the accurate temperature detection function of the temperature sensor group 30. In other words, if Permission Condition 2 is not met, acquisition of recipe data CD is not permitted.

Next, FIG. 37 will be described.
In Fig. 37, steps SS1 to SS8 are operation steps for "obtaining recipe data CD" in the cooperative cooking mode defined in the integrated control program of the control device 22. There are no substantial differences from the operation steps shown in Fig. 36.
As described above, the combined cooking mode KM1 is a mode in which the first heating means HM1 and at least one of the second and third heating means HM2 and HM3 are used in combination.

Therefore, as is clear from FIG. 37, when acquiring recipe data CD from an external device for one of the cooking menus in the cooperative cooking mode KM1 (for example, "roast beef" or "ratatouille"), it is particularly important to select the heating means to be used in step SS4A.
Therefore, in this step SS4A, in order to select the second heating means HM2 or the third heating means HM3 and to select one of the heating ports 4L, 4C, and 4R, an input operation corresponding to one of the three areas from the left area 15L to the right area 15R is performed by operating the recipe data acquisition key 75.

For example, when the right shared key 42R is operated, the cooking appliance 1 is permitted to transmit to the communication terminal 200 or the cloud server 300 recipe data CD for both the "basic menu" (including eight types such as "hamburger steak" described in embodiment 1) that is initially stored (stored) in the cooking appliance 1 and the additional menu (such as the "ratatouille"), but these cooking menus are not sent all at once, and the provision of data for only one cooking menu related to the "advance notice information" transmitted in advance from the communication terminal 200 or the like is requested.
Then, the control device 22 of the cooking appliance 1 starts a preparation process for acquiring one piece of recipe data CD.

Next, we will explain Figure 38.
Fig. 38 shows the state after the recipe data CD for one cooking menu (roast beef) in the cooperative cooking mode KM1 has been acquired. Fig. 38 is an explanatory diagram 3 showing the display state and input operations of the integrated display unit 15 and the central operation unit (rear operation unit and front operation unit) 17.

As is clear from Figure 38, when recipe data CD is acquired from outside for one cooking menu (e.g., "roast beef") in the cooperative cooking mode KM1, if cooking step 1 of that cooking menu is set by default to be performed using the right heating port 4R, then identification information 72 and a summary display 72P of the cooperative cooking mode KM1 will be displayed in text in the right (third) area 15R.
Therefore, when starting cooking of this recipe (roast beef), it is sufficient to touch the one right cut-on key 41R corresponding to the right area (third area) 15R.
In the embodiment shown in Figure 38, the right cut-in key 41R can be clearly distinguished from the other input keys by the light emission control unit 37, which illuminates the entire touch key portion from below with light of a specific color or displays it illuminated with a flashing light, thereby emphasizing that the key that the user should operate is the right cut-in key 41R.

Summary of embodiment 2.
As is clear from the above description, in the second embodiment, the cooking device 1 according to the third disclosure is disclosed as follows.
That is, one embodiment of the cooking device 1 according to the third disclosure is as follows:
a first heating means HM1 for performing a heating operation at the left heating port 4L and the right heating port 4R, which are respectively arranged on the top surface of the main body 2;

In the above explanation, for the sake of simplicity, reference numerals have been used to indicate corresponding components and signals, but these reference numerals should not be interpreted as indicating that the components and signals are different from one another. Although different reference numerals are used in some cases, this is for the sake of explanation, and does not mean that the data, components, or functional content are different from one another solely due to the difference in reference numerals.

The circuits, parts, and device components illustrated in the above embodiments 1 and 2 are conceptual in nature and do not necessarily have to be physically configured as illustrated. Furthermore, the functions of the control device 22, heating control unit 23, first heating means HM1, second heating means HM2, third heating means HM3, memory device 21, etc., in particular, can be distributed or integrated, and the specific configuration is not limited to that illustrated; all or part of them can be functionally or physically distributed or integrated in any unit depending on the function, operating status, etc.

The functions of the control device 22 and heating control unit 23 are realized by processing circuits. The processing circuits that realize each function may be dedicated hardware or may be processors that execute programs stored in memory.

When the processing circuit is a processor, the functions of the control device 22 and heating control unit 23 are realized by software, firmware, or a combination of software and firmware. The software and firmware are written as programs and stored in the storage device 21, which is memory. The processor realizes the functions of the control device 22 and heating control unit 23 by reading and executing the programs stored in the storage device 21.

These programs cause the microcomputer to execute the control procedures of the control device 22 and heating control unit 23. The storage device 21 is typically a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM.

Furthermore, some of the data and programs in the recipe data storage unit 21 shown in FIG. 5 may not be stored in the cooker 1 but in an external recording medium (such as a storage server). In this case, the cooker 1 accesses the external recording medium (storage server) to obtain the necessary data and program information.

Furthermore, the operating programs of the control device 22, first heating means HM1, second heating means HM2, and third heating means HM3 may be updated with appropriate modifications and improvements at the request of the user or the manufacturer of the cooking appliance 1. In this case, the modified and improved programs may be obtained, for example, via the communication unit 25.

One of the heating parts (IH coils 9L, 9C, 9R) of the first heating means HM1 that heats and cooks food on the top plate 3 may be replaced with a gas combustion burner. In this case, a gas flow valve is controlled by the control device 22.
Also, a part or all of the second heating means HM2 or the third heating means HM3 may be replaced with a gas combustion burner or an induction heating source.

In the first and second embodiments, the input operation unit 36 has been described as primarily a "contact input" type, in which the user touches an input key to issue an input command, and a pressure (push button) type operation unit, but a dial-type input means, in which the user inputs by rotating it, may also be used in combination.

Furthermore, the input operation unit 36 in embodiment 1 has a voice signal receiving unit 31 and is configured to directly receive and input voice utterances from the user. However, commands may also be given to the cooking appliance 1 via an input terminal device equipped with a voice input function, such as a smart speaker or AI speaker. In this case, the voice signal receiving unit 31 can be omitted. The voice input result from the input terminal device may be input to the voice signal analysis unit 32 as an external electrical signal via the communication unit 25.

Furthermore, the smart speaker or AI speaker can wirelessly exchange information at any time with a support server equipped with voice translation and search functions in a network environment, such as a cloud server 300.
Therefore, the voice (natural language) uttered by the user near the cooking appliance 1 can be acquired as a voice signal, converted into a command signal from the user by the support server, and ultimately a command signal for the cooking appliance 1 can be generated.
Therefore, by using such a voice input method, even if the user is near the cooking appliance 1, and both hands are occupied preparing food or processing ingredients, limiting the frequency with which the user can directly touch the input operation unit 36, the cooking appliance 1 can be operated with natural speech (voice), which is convenient.

In the first embodiment, the cooking appliance 1 receives recipe data CD and other data directly or via the wireless router 201 from the communication terminal (information processing terminal) 200, the first server 321, etc., but the cooking appliance 1 may also receive the data via another relay device. For example, the remote control of another home appliance (e.g., a water heater) installed in the kitchen may be used as the relay device. Such remote controls are conveniently usually connected to a power source at all times. In this case, it is desirable for the relay device to have a built-in storage device (e.g., flash memory) that temporarily stores various data, including commands transmitted from the information processing terminal 200, the cloud server 300, etc. The relay device is then configured to temporarily store various data transmitted from the cooking appliance 1 in the storage device (e.g., flash memory).

The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The true scope of the present invention is indicated by the claims, not the above description, and is intended to include all modifications within the meaning and scope of the claims.

The cooking appliance and cooking system disclosed herein can be widely used not only in kitchens of ordinary homes, but also in kitchens in public facilities, stores, etc.
