Description

The present invention relates to a cooking system that includes a cooking container and a cooking device that can use the cooking container.

Conventionally, there is known a cooking device that has a grill burner that heats the inside of the grill chamber, and that can store a cooking container containing food inside the grill chamber and heat and cook the food.

For example, in the cooking device of Patent Document 1 below, a metal or ceramic cooking utensil such as a Dutch oven (waterless cooking device) is stored inside the grill chamber. A Dutch oven is a cooking container in which the container body and container lid are separate members, and can be used for waterless cooking.

This cooking device has an upper burner in the center of the top wall of the grill chamber for heating the cooking container from above. In addition, lower burners are provided below the centers of the left and right side walls of the grill chamber for heating the cooking container from the sides and below (Patent Document 1, paragraph 0021, Figure 2).

JP 2019-000146 A

However, in the cooking device of Patent Document 1, when grilling, it is difficult to tell whether the container body and container lid of the cooking container are completely closed. Furthermore, there is a problem in that cooking can fail if grilling is started in a state where the container lid is not completely closed relative to the container body (abnormal setting).

The same thing happens when using the cooking container on a stove burner, and there have been cases where the user cooks food without realizing that the container lid is not completely closed on the container body, resulting in failure.

The present invention was made in light of this background, and aims to provide a cooking container that can determine whether the container lid is set correctly on the container body, preventing cooking failures.

In order to achieve the above object, a first aspect of the present invention provides a cooking system including a cooking device capable of using a cooking container having a container body and a container lid that fits over and covers the container body from above, and an imaging device,
The container body has a mounting portion on which a peripheral edge of the container lid is mounted,
The placement portion is provided with an identification body that is covered by the container lid when the container lid is fitted to the container body and at least a part of which is exposed to the outside when the container lid is not fitted to the container body,
The imaging device includes:
an imaging unit that captures an image of an area including a cooking container on a stove or a grill of the cooking device to obtain an image;
a storage unit that stores a template image of the cooking container when the container lid is fitted to the container body;
a determination unit that compares the captured image captured by the imaging unit with the template image stored in the memory unit, and when the cooking container on the stove or grill is recognized as the stored cooking container, determines whether the container lid is fitted to the container body by detecting the identifier with the imaging device; and
The present invention is characterized in that it is provided with:

In the cooking system of the first invention, the placement unit is provided with an identifier that is covered by the container lid when the container lid is fitted to the container body, and at least a part of which is exposed to the outside when the container lid is not fitted to the container body. When the user visually recognizes the identifier, the user recognizes that the container lid is not fitted to the container body and the container lid is not set correctly (abnormal setting). This cooking container makes it easy to determine whether the container lid is set correctly to the container body, so that cooking failures can be prevented. In addition, the imaging unit of the imaging device images an area including the cooking container on the stove or grill of the heating cooker and obtains the image. The determination unit compares the image captured by the imaging unit with a template image stored in the memory unit. Here, the template image consists of an image of the cooking container when the container lid is fitted to the container body. For this reason, the cooking container on the stove or grill can be recognized as the cooking container stored in advance, and when the identifier is detected, or when a shift or break in the integral identifier is detected, it is determined that the container lid is not fitted to the container body and is not set correctly (abnormal setting). The cooking system can automatically recognize when a container lid is not set correctly, thereby reliably preventing cooking failures.

In the cooking system of the first invention, the identifier is provided on approximately the entire periphery of the placement portion,
It is preferable that the identifier has a different color from the other parts of the container body, or that a pattern or a mark is affixed as the identifier.

According to this configuration, since the identifier is provided around almost the entire circumference of the mounting portion, if the container lid is misaligned even slightly, the identifier will be visible to the user. The identifier may also be a color different from the other parts of the container body, or may have a pattern or mark. This allows the user to easily determine whether the container lid is set correctly on the container body.

In order to achieve the above object, a second aspect of the present invention provides a cooking system including a cooking device capable of using a cooking container having a container body and a container lid that fits over and covers the container body from above, and an imaging device,
The container body has a mounting portion on which a peripheral edge of the container lid is mounted,
The container lid and the placement portion are provided with an identifier that forms a continuous, integrated shape when the container lid is fitted to the container body, and that causes the integrated shape to shift or be interrupted when the container lid is not fitted to the container body;
The imaging device includes:
an imaging unit that captures an image of an area including a cooking container on a stove or a grill of the cooking device to obtain an image;
a storage unit that stores a template image of the cooking container when the container lid is fitted to the container body;
a determination unit that compares the captured image captured by the imaging unit with the template image stored in the memory unit, and when the cooking container on the stove or grill is recognized as the stored cooking container, determines whether the container lid is fitted to the container body by detecting a shift or interruption of the identifier by the imaging device; and
The present invention is characterized in that it is provided with:

In the cooking system of the second invention, an identifier is provided on the placement portion of the container lid and the container body, which has a continuous integral shape when the container lid is fitted to the container body, and the integral shape is shifted or interrupted when the container lid is not fitted to the container body. When a user recognizes the shift or interruption of the identifier, which has an integral shape (for example, a linear pattern) when fitted, the user recognizes that the container lid is not fitted to the container body and the container lid is not set correctly (abnormal setting). Since this cooking container makes it easy to determine whether the container lid is set correctly to the container body, cooking failures can be prevented. In addition, the imaging unit of the imaging device images an area including the cooking container on the stove or grill of the heating cooker and obtains the image. The determination unit compares the image captured by the imaging unit with a template image stored in the memory unit. Here, the template image is an image of the cooking container when the container lid is fitted to the container body. For this reason, the cooking container on the stove or grill can be recognized as a pre-stored cooking container, and if an identifier is detected, or if the integral identifier is misaligned or broken, it is determined that the container lid is not fitted to the container body and is not set correctly (abnormal setting).The cooking system can automatically recognize when the container lid is not set correctly, and therefore can reliably prevent cooking failures.

In the heating and cooking system of the first or second invention,
The cooking appliance or the imaging device includes a notification unit,
It is preferable that the notification unit issues a notification when the determination unit has detected the identifier for a certain period of time or has detected a deviation or interruption of the identifier for a certain period of time.

According to this configuration, when the determination unit detects the identifier for a certain period of time, the notification unit issues a notification of an abnormal setting. Furthermore, in the case of an identifier having an integrated shape, when the determination unit detects a misalignment or disconnection of the identifier for a certain period of time, the notification unit issues a notification of an abnormal setting. This makes it possible to not issue a notification when there is no need for a notification, such as when a user removes a container lid to check the contents of a cooking container on a stove or grill.

Below, an embodiment of the present invention will be described with reference to the drawings.

First, referring to FIG. 1, a cooking system 1 according to an embodiment of the present invention (third invention) will be described. The cooking system 1 is mainly composed of a cooking device 10 and an imaging device 20, and the imaging device 20 is a system that can capture images of the cooking status of the cooking device 10.

First, the cooking device 10 will be described. A grill door 2 is provided in the center of the front side of the cooking device 10. The grill door 2 opens and closes the front opening of the grill chamber 2a provided inside the cooking device 10 when putting or removing an object to be heated into or from the grill chamber 2a.

The cooking device 10 is a built-in type that is incorporated into the countertop W of a system kitchen, and is equipped with a box-shaped stove body 3 with an open top. A top plate 4 is provided on the top of the stove body 3, and stove burners 5, 6, and 7 supported by the stove body 3 are exposed upward from the top plate 4. Here, a cooking container 9 is placed on the stove burner 5. The cooking container 9 is a so-called waterless cooker consisting of a container body and a container lid that covers the container body from above.

In addition, on both sides of the grill door 2 on the front side of the cooking device 10, there are buttons 13a to 13d for turning on and off the burners 5, 6, and 7, and the grill burner 8 in the grill chamber 2a, as well as a power switch 13e.

Each of the extinguishing buttons 13a to 13d is a push type, and when it is pushed once from the extinguishing position shown in Figure 1, where it is recessed into the front panel, and then released, it protrudes to the combustion position in front of the front panel, and in this state it can be rotated to adjust the flame strength.

Signals from the power switch 13e and the operation detection switches (not shown) of the ignition/extinguishing buttons 13a-13d of each burner 5-8 are input to the control unit 11, which is made up of a microcomputer and will be described later, along with signals from the flame detection elements of each burner 5-8. The control unit 11 then controls the igniter, main valve, and each gas valve device.

Next, the imaging device 20 will be described. The imaging device 20 is located above the cooking appliance 10 and is attached to the lower end frame 30 of the ventilation fan hood. Details will be described later, but the imaging section 21 of the imaging device 20 can capture images of an imaging area that includes the stove burners 5 to 7 of the cooking appliance 10 and an imaging area that includes the grill chamber 2a.

Next, the internal configuration of the cooking device 10 and the imaging device 20 will be described with reference to FIG. 2.

First, the cooking device 10 is composed of a control unit 11 and an operation unit 13. The control unit 11 mainly controls the heat of the stove burners 5 to 7 and the grill burner. The control unit 11 receives operation commands from the operation unit 13, which consists of on/off buttons 13a to 13d, etc., and turns each stove burner on or off.

Next, the imaging device 20 is composed of an imaging section 21, a determination section 23, a storage section 25, and a notification section 27. The imaging section 21 is, for example, a web camera, and is installed in a position where it can capture images of the stove burners 5 to 7 and their surrounding areas (including the grill chamber 2a in the pulled-out state). It is preferable that the imaging section 21 can zoom in and out and adjust the angle, and that the position of the imaging area can be changed.

The imaging unit 21 captures images of the stove burners 5 to 7 and their surrounding areas, and transmits the captured images (still or video) to the determination unit 23. The determination unit 23 compares the captured image with a template image stored in the memory unit 25, and first determines whether the cooking vessel is a pre-registered waterless cooker. If it is a waterless cooker, it then determines whether the container lid fits properly with the container body.

The template image stored in the memory unit 25 is composed of an image of the cooking container when the container lid is fitted to the container body. If there are multiple types of cooking containers with lids for the cooking device 10, images of each cooking container are stored and registered in the memory unit 25.

Next, the cooking container of the present invention (first invention) will be described with reference to Figure 3. As shown in Figure 3(a), when the container lid 9b of the cooking container 9 is closed, the container lid 9b is placed on top of the container body 9a. Also, Figure 3(b) shows the container lid 9b in a lifted state. Details will be described later, but the edge (flange) of the container body 9a has a placement portion 9a1 on which the edge (periphery 9b1) of the container lid 9b is placed.

Figure 3(c) shows a cross-sectional view of the cooking container 9 (in a properly set state). The container body 9a has a wall portion 9a2. The wall portion 9a2 extends in the height (depth) direction of the container body 9a, and is connected at its lowermost portion to the bottom surface 9a3 (see Figure 3(b)). The wall portion 9a2 is also connected at its uppermost portion to the mounting portion 9a1. An identifier P is provided at the end of the mounting portion 9a1 on the wall portion 9a2 side.

The top surface 9b2 of the container lid 9b has a predetermined height, but is a plate portion that is approximately parallel to the bottom surface 9a3 of the container body 9a, and its end is connected to the periphery 9b1. The container lid 9b also has a fitting portion 9b3 that extends from the top surface 9b2 below the periphery 9b1. In the present invention, "fitting" refers to the container body 9a and the container lid 9b becoming one unit by fitting the fitting portion 9b3 of the container lid 9b into the wall portion 9a2, which is the fitted portion of the container body 9a.

The fitting portion 9b3 may be fitted onto the mounting portion 9a1 of the container body 9a. Alternatively, the wall portion 9a2 of the main container body 9 may have a protrusion at its top that protrudes toward the center of the main container body 9. In this case, the protrusion corresponds to the fitted portion of the container body 9a.

In addition, on the mounting portion 9a1, an identifier P is provided that is covered by the container lid 9b (periphery 9b1) when the container lid 9b is fitted to the container body 9a around its entire circumference. When the container lid 9b is not fitted, at least a part of the identifier P is detected, so the determination unit 23 can detect a state in which the container lid 9b is not fitted to the container body 9a and the container lid 9b is not correctly set to the container body 9a (abnormal set state). It is preferable that the periphery 9b1 is equal to or smaller in size than the mounting portion 9a1 of the container body 9a. In addition, the identifier P may be circumferential (almost entirely circumferential) with a portion missing.

The determination unit 23 can also recognize the state of the flames on the burners 5 to 7, or whether or not a cooking container 9 is placed at each of the burners 5 to 7, and can also determine which of the burners 5 to 7 are in use and which are not.

The notification unit 27 issues a notification when the determination unit 23 detects the identifying object P for a certain period of time (e.g., several tens of seconds). For example, when a user removes the container lid 9b of the cooking container 9 on the stove burner 5-7 to check the contents, the detection of the identifying object P takes several seconds, which does not reach the certain period of time, so no notification is issued. Note that this notification is preferably issued by a warning sound or voice.

In addition, when the determination unit 23 detects almost the entire circumference of the identifier P, the notification unit 27 can issue a notification that the container lid 9b is not placed on the container body 9a. In this case, it may be determined that the container lid 9b has been opened during cooking and a notification to that effect may be issued. Note that even when this notification is issued, cooking can be continued without the container lid 9b.

Next, the imaging area of the imaging device 20 will be described with reference to Figures 4A and 4B.

Figure 4A shows the state when the image of the top surface of the stove burners 5 to 7 of the cooking appliance 10 is captured by the imaging device 20. The determination unit 23 detects the cooking vessel 9 on the stove burner 5 from the captured image and focuses on the surrounding area R1 of the cooking vessel 9. Of course, if the cooking vessel 9 is on the stove burner 6, the determination unit 23 will focus on the surrounding area.

The determination unit 23 compares the cooking container 9 with the template image to determine that the cooking container 9 is a waterless cooker, and then detects the identifier P to determine whether the container lid 9b is abnormally set relative to the container body 9a. If the identifier P of the container body 9a is detected, the determination unit 23 determines that the container lid 9b is abnormally set.

Next, FIG. 4B shows the state when the image of the top surface of the grill chamber 2a (partially pulled out) of the cooking appliance 10 is captured by the imaging device 20. The determination unit 23 detects the cooking container 9 on the grill chamber 2a from the captured image and focuses on the surrounding area R2 of the cooking container 9. The determination unit 23 then uses the template image to determine that the cooking container 9 is a waterless cooker, and then determines whether the container lid 9b is abnormally set relative to the container body 9a.

The determination unit 23 determines that the cooking container 9 is a waterless cooker by comparing it with the template image, and then determines that an abnormal setting state has occurred if the identifier P on the container body 9a is detected.

Here, Fig. 5A shows a top view of the cooking container 9. Fig. 5A(a) is a top view of the container body 9a, which has a mounting portion 9a1 on which the rim 9b1 of the container lid 9b is placed. In addition, an identifier P is provided on the mounting portion 9a1.

As shown in FIG. 5A (b), the identifier P is provided in a position that is not visible to the user when the container lid 9b is fitted into the container body 9a (properly set state). It is preferable that the identifier P has a color different from other parts of the container body 9a (particularly the edge on which the container lid 9b is placed). This allows the determination unit 23 to determine that the container lid 9b is properly set into the container body 9a.

As shown in FIG. 5A(c), when the container lid 9b is not fitted to the container body 9a (abnormal setting state), the abnormal setting state is easily recognized from the image captured by the imaging device 20. This allows the determination unit 23 to determine that the setting of the container lid 9b is abnormal by detecting the identifier P.

As an alternative embodiment of the identifier, it may be visually distinguishable by having a predetermined pattern applied along the mounting portion 9a1, or by having a mark such as a figure, mark, or letter attached thereto.

The identifier may also be in the form shown in FIG. 5B. Below, the cooking container of the present invention (second invention) will be described with reference to FIG. 5B.

Figure 5B (a) is a top view of a cooking container 19 consisting of a container body 19a and a container lid 19b. The container body 19a has a mounting portion 19a1 on which the rim of the container lid 19b is placed. In addition, identifiers Qa and Qb are provided on the mounting portion 19a1 and the top surface of the container lid 19b, respectively. When the container lid 19b is fitted into the container body 19a (normally set state), the identifiers Qa and Qb form a continuous, linear, integrated shape (identifier Q).

On the other hand, as shown in FIG. 5B(b), when the container lid 19b is not fitted to the container body 19a (abnormal set state), the integrated shape of the identifier Q becomes misaligned midway, or the container lid 19b shifts sideways and the identifier Q is interrupted. Since the shift of the identifier Q is easily recognized from the image captured by the imaging device 20, the determination unit 23 can determine that the set of the container lid 19b is abnormal by detecting the shift of the identifier Q.

The direction, width, and number of lines of the identifier Q are arbitrary. Furthermore, the identifier Q is not limited to being linear, and may be a symbol such as a figure, mark, or letter that is applied to the boundary portion when the container lid 19b is placed on the container body 19a.

The notification unit 27 of the imaging device 20 issues a notification when the determination unit 23 detects a shift or interruption in the identifier Q for a certain period of time (e.g., several tens of seconds). For example, when a user removes the container lid 19b of the cooking container 19 on the stove burner 5-7 to check the contents, the detection of the shift or interruption in the identifier Q takes several seconds, which does not reach the certain period of time, so no notification is issued.

In addition, when the determination unit 23 cannot detect the identifier Qb of the container lid 19b, the notification unit 27 can notify the user that the container lid 19b is not placed on the container body 19a. In this case, the notification unit 27 may determine that the container lid 19b has been opened during cooking and notify the user of this fact.

Finally, referring to FIG. 6, a flowchart of the cooking system 1 when using the cooking container 9 will be described. Note that the following steps are constantly executed mainly by the imaging device 20 of the cooking system 1.

First, the imaging device 20 is turned on (STEP 01). This causes the imaging section 21 of the imaging device 20 to start capturing images of the area surrounding the grill chamber 2a and the stove burners 5 to 7.

Next, the imaging device 20 determines whether the grill is in use or not (STEP 02). Specifically, the determination unit 23 of the imaging device 20 analyzes the image captured by the imaging unit 21 and determines whether the grill door 2 is open or not. If the grill is in use, the process proceeds to STEP 03, and if the grill is not in use, the process proceeds to STEP 04.

If the grill is in use ("YES" in STEP 02), the imaging device 20 captures an image of the imaging area R2 (see FIG. 4B), and the determination unit 23 starts detecting the grill area (STEP 03). Then, proceed to STEP 05.

On the other hand, if the grill is not in use ("NO" in STEP 02), the imaging device 20 captures an image of the imaging area R1 (see FIG. 4A), and the determination unit 23 starts detecting the stove area (STEP 04). Then, proceed to STEP 05.

Next, the imaging device 20 determines whether or not a cooking vessel 9 is present (STEP 05). This determination is made using a template image, and determines whether the cooking vessel 9 is a waterless cooker that can be used both in the grill chamber 2a and on the stove burners 5 to 7. If a cooking vessel 9 (waterless cooker) is present in the grill chamber 2a or on one of the stove burners 5 to 7, the process proceeds to STEP 06; if not, the process returns to STEP 02.

If the cooking container 9 is present ("YES" in STEP 05), the imaging device 20 determines whether an identifier for the cooking container 9 has been detected (STEP 06). If the container lid 9b is abnormally set relative to the container body 9a, the identifier P is detected. If the identifier P is detected, proceed to STEP 08, and if not, proceed to STEP 07.

First, if the identifier P is not detected ("NO" in STEP 06), the image capture device 20 recognizes that the container lid 9b is set correctly on the container body 9a (STEP 07). This is because the identifier P is not captured when the container lid 9b is set correctly. In this case, the process returns to STEP 02.

Next, if the identifying object P is detected ("YES" in STEP 06), the imaging device 20 judges whether the identifying object P has been detected for a certain period of time (e.g., several tens of seconds) (STEP 08). This takes into consideration the case where the identifying object P is detected temporarily when the user opens the container lid 9b or moves the position. If the identifying object P has been detected for a certain period of time, the process proceeds to STEP 09, and if it has not been detected for a certain period of time, the process returns to STEP 02.

If the identifying object P has been detected for a certain period of time ("YES" in STEP 08), the image capture device 20 determines whether the entire circumference of the identifying object P has been detected (STEP 09). If the entire circumference of the identifying object P has been detected, the process proceeds to STEP 10, and if the entire circumference of the identifying object P has not been detected (if only a part of the identifying object P has been detected), the process proceeds to STEP 11.

First, when the entire circumference of the identification object P is detected ("YES" in STEP 09), the imaging device 20 notifies the notification unit 27 that the container lid 9b is not placed (STEP 10). Then, the process returns to STEP 02.

On the other hand, if the entire circumference of the identifier P is not detected ("NO" in STEP 09), the imaging device 20 notifies the notification unit 27 that the container lid 9b is abnormally set, i.e., that the container lid 9b is in an abnormally set state (STEP 11). Then, the process returns to STEP 02. In this way, in the cooking system 1, the imaging device 20 notifies or warns that the container lid 9b is in an abnormally set state or that the container lid 9b has been left attached. This makes it possible to prevent cooking failures caused by the container lid 9b not sealing the container.

In the above flowchart, the imaging device 20 checks for the presence of a cooking container 9 in either the area above the grill chamber 2a of the cooking device 10 or the area above the stove burners 5 to 7 (STEPs 02 to 05), but it may check both areas in turn. It may also be possible to check both areas simultaneously and make the above determination for the area where the cooking container 9 is present.

When a cooking container 19 (see FIG. 5B) having an identifier Q is used in the cooking system 1, the above flowchart is processed as follows. The processes in STEPs 01 to 07 are the same, but in STEP 08, the imaging device 20 determines whether a shift or interruption in the identifier Q has been detected for a certain period of time (e.g., several tens of seconds).

If a shift or disconnection of the identifier Q is detected for a certain period of time, proceed to STEP 09, where the imaging device 20 determines whether or not the identifier Qb of the container lid 19b is detected. If the identifier Qb is detected, the imaging device 20 notifies the notification unit 27 that the container lid 19b is abnormally set, i.e., that an abnormally set state exists.

On the other hand, if the identifier Qb is not detected, the imaging device 20 notifies the notification unit 27 that the container lid 19b is not placed. In this way, the cooking system 1 can also accommodate the use of a cooking container 19 having an identifier Q.

In the above embodiment, the imaging device 20 performs the process from determining whether the container lid 9b is abnormally set to notifying the user, but this is not limited to the above embodiment. For example, the cooking appliance 10 and the imaging device 20 may be capable of communicating with each other, the cooking appliance 10 may include a notification unit, and the cooking appliance 10 may be responsible for notifying the user. Alternatively, the imaging device 20 may transmit the captured image to the cooking appliance 10, and the cooking appliance 10 may be responsible for the processes from the determination onward.

Regarding the notification, a voice notification has been described, but when the notification is made on the cooking appliance 10 side, the notification may be made on a liquid crystal display device or the like. Also, the template image was stored in the memory unit 25 of the imaging device 20, but it may be stored on an external server that can communicate with the imaging device 20.
