Description

  The present invention relates to a drawer-type heating cooker in which a drawer body can be pulled out and housed with respect to a cooker body, and an opening of a heating chamber can be sealed with an opening / closing door in the housed state.

  Conventionally, a drawer body on which an object to be heated can be placed can be pulled out together with an opening / closing door with respect to the cooker body. A drawer-type heating cooker that can be closed is proposed (Patent Document 1, Patent Document 2). In this type of drawer-type heating cooker, an apparatus main body (cooker main body) having a cooking chamber (heating chamber) that accommodates an object to be heated, an open / close door that shuts off the cooking chamber from the outside air, and interlocked with the open / close door And a heating container (drawer) on which a bottom plate or an object to be cooked can be placed. More specifically, the bottom plate or the heating container is smoothly slid by the slide mechanism, and the rotation output of the motor is transmitted to the sliding mechanism via a transmission means such as a rack and pinion mechanism, so that the bottom plate or the heating container is attached to the device. The main body can be pulled out or moved in the receiving direction. In a state where the bottom plate or the heating container is accommodated in the device main body, the open / close door blocks the cooking chamber from the outside air. The heating cooker described in Patent Document 2 forms a heating chamber for confining microwaves by covering the opening of the heating container having an opening formed in the upper part thereof and capable of being pulled out from the cooker main body with a lid portion. Leakage of radio waves is prevented by providing a choke groove between the opening peripheral edge of the lip and the lid.

As described above, in the drawer-type heating cooker, the drawer body connected to the door is electrically opened and closed to easily place and take out the food that is the object to be heated, and the door is opened and closed by a conventional manual operation. Compared to a cooking device, it offers superior convenience. Conventionally, household appliances such as refrigerators, dishwashers, and microwave ovens installed in the kitchen open and close the doors by the user's operating force. Since equipment occupies almost everything and is unfamiliar with the electric opening and closing operation, safety considerations are necessary.
For example, in the automatic opening / closing door mechanism of the above-described conventional drawer-type heating cooker, a user who operates with an awareness of automatic opening / closing can expect the opening / closing operation to occur. Will occur. In addition, when the user himself / herself performs an opening / closing operation unintentionally, an unexpected opening / closing operation occurs.
In such a case, the drawer body with a relatively large mass operates, so that when the door is closed, fingers or the like are caught in the door, or a part of the body collides without being aware of the operation of the door. There is a possibility.
Also, the required opening / closing distance required for the door depending on the installation conditions of the heating cooker, the usage conditions such as the user's lifestyle, or the characteristics of the heated object such as the size of the heated object and the ease of overflow from the container Since the opening / closing speed is different, a method for notifying the user of the opening / closing operation conditions of the door is required.

  Although it is different in the technical field to issue a warning sound at the time of drawing, it has been proposed to generate a warning warning sound in an image recording apparatus (Patent Document 3). That is, when an empty state of a hopper containing recording material such as recording paper or a full stacker is detected, the hopper or stacker is pulled out, and at that time, a warning sound generating means such as a buzzer is activated. In addition to notifying the operator of each state, attention is given to the periphery of the hopper or stacker that is being pulled out.

Patent Document 4 discloses a method for setting a notification sound of home appliances by adding sound elements such as rhythm, scale, and inflection to different types of notification sounds of a plurality of devices. A technical method for defining a notification sound that can be clearly distinguished has been proposed.
Japanese Patent Application Laid-Open No. 3-45820 (page 2, lower left column, line 6 to page 3, upper right column, line 16, FIG. 1 to FIG. 1) Japanese Patent Laid-Open No. 11-237053 (paragraphs [0029] to [0032], FIG. 1) JP-A-8-175746 (paragraph [0019], FIG. 7) Japanese Patent Application Laid-Open No. 9-101796

  Therefore, in the drawer-type heating cooker, when opening and closing the automatic opening / closing door, the people around the drawer-type heating cooking appliance other than the person who operates it are also urged to call attention to the movement of the opening / closing door. There are issues to be solved.

  The purpose of this invention is to prompt attention to the movement of the door, not only to the person who operates it, but also to the people around the other drawer-type heating cooker when opening and closing the automatic opening and closing door, It is an object of the present invention to provide a drawer-type heating cooker that can prevent dangers such as a collision caused by an open / close door or a pinching of a hand or a finger caused by a close door.

  In order to solve the above-described problems, the drawer-type heating cooker according to the present invention can draw out and store the drawer body on which the object to be heated is placed with respect to the main body of the cooker, and the opening of the heating chamber in the stored state. In a drawer-type cooking device that can be closed by an open / close door, a sound setting is made to generate different warning sounds for the opening / closing operation of the opening / closing door and the closing operation of the opening / closing door, and the opening operation of the opening / closing door. In the closing operation of the opening / closing door, the warning sound in which the sound is set for the operation is generated.

  According to this drawer-type heating cooker, a warning sound that is set for the operation is generated during the opening and closing operation of the opening and closing door. The person around the cooking device is alerted by a warning sound that is set for the door opening operation, so that the door that opens and closes can be prevented from colliding unexpectedly with a person or an object. In addition, even when the door is automatically closed, the warning sound that is set for the closing operation is alerted to prevent the hand, fingers, or objects from being caught by the door that is about to close. Accidents can be prevented in advance. In addition, when the door is moved because the door opening / closing key of the drawer-type heating cooker is touched unconsciously, a person in the vicinity can immediately recognize such an unexpected movement of the door by a warning sound. Furthermore, by generating a warning sound according to the user's preference during automatic opening / closing according to sound settings, there is an effect of eliminating undesirable mechanical sounds during drawer opening / closing.

In this drawer-type heating cooker, the setting of the warning sound can be changed.
For example, as for the sound setting, if the setting is made such that the increase and decrease of the frequency are compared with the warning sound at the time of automatic opening and closing, it is easy for the user to distinguish. In addition, if the warning sound thus compared is modified or changed in accordance with characteristics such as the amount of the object to be heated or the amount of heat, the warning sound can be used without impairing the ease of distinguishing the warning sound. The impression given to the person can be changed. For example, when it is difficult to hear high-frequency sound, it is possible to make the warning sound contrast easy to hear by moving the scale.

  As an example of changing the warning sound, it can be changed according to the opening distance of the door. That is, the sound setting can be used properly according to the length of the opening distance of the door. In addition, for the warning sound, an example of setting the warning sound for opening and closing is prepared based on the above-mentioned ease of discrimination, and if it can be selected by the user, it is inappropriate for the user's sense, sensitivity, and usage environment. This is more preferable because it is possible to avoid such a setting.

  In the drawer-type heating cooker in which the sound setting can be changed, the sound setting of the warning sound can be determined according to the opening / closing speed of the opening / closing operation of the opening / closing door. When the opening / closing speed of the open / close door is fast, there is a high risk of colliding with a person or an object or pinching a hand, a finger or an object. Accordingly, in order to obtain a warning sound with higher warning performance as the opening / closing speed of the open / close door is faster, it is preferable to perform settings such as acceleration of the rising speed of sound frequency and gradual increase in volume. Conversely, when the opening / closing speed of the open / close door is slow, it is preferable to set a sound with a low warning sound.

  Furthermore, the opening / closing speed of the opening / closing door can be set to be changeable according to a use condition of the user and characteristics of the object to be heated. Generally, it is preferable that the object to be heated after cooking is cooked before it is cooled, so that it is required to open the door as quickly as the user desires. When the user wants relatively quick action, if the door opening operation is slow, the user may intervene in the door opening operation and promote the door opening manually. Because there is concern about food spills, it is desirable to accelerate the opening operation. However, if the user does not want to handle hot food for serving, it is desirable to open the door gently.

As the characteristics of the object to be heated, for example, when the object to be heated is a liquid, a large amount of water vapor may be generated. Furthermore, it is preferable that the opening speed of the liquid is suppressed because the liquid object to be heated may be shaken in the container or spilled due to the container falling.
In particular, when an unfamiliar operation such as a child takes out food, it is preferable to reduce the opening speed from the viewpoint of risk prevention. For example, a setting button similar to a child lock button is provided in the operation unit, and if the door open button and child lock button are pressed at the same time, the door opens rapidly, and if only the door open button is pressed, the door opens gently. It is more preferable to do so.
As described above, it is desirable to determine the opening / closing speed of the open / close door according to the use conditions of the user and the characteristics of the object to be heated.

  In the drawer-type heating cooker in which the sound setting can be changed, the sound setting of the warning sound can be determined according to the maximum opening distance of the door. For example, when the maximum opening distance is set to be long, it can be associated with a sound having a high warning property. Conversely, when the maximum opening distance is set short, it can be associated with a sound with low warning.

  In the drawer-type heating cooker, the maximum opening distance of the open / close door can be set according to a user's use conditions or the characteristics of the object to be heated. For example, by changing the opening / closing distance according to the object to be heated, it is possible to eliminate the need to secure a useless opening / closing distance and time. Further, since the user can set the opening / closing distance of the opening / closing door, it is possible to prevent danger and prevent collision with furniture.

  In this drawer-type cooking device, it is preferable that the user can further change the sound setting of the warning sound. As a drawer-type cooking device, it can be set in advance according to the opening / closing speed and maximum opening distance of the door, but depending on the user, the sound setting has been changed to make it easier to distinguish the warning sound. It is preferable to make it possible.

Since the drawer-type heating cooker according to the present invention is configured as described above, a warning sound is generated when the door is opened and closed, and when the door is automatically opened, it is automatically opened to the people around the heating cooker. It is possible to prevent a door that automatically opens by calling attention with a warning sound according to the situation from unexpectedly colliding with a person or an object, and further preventing a person or an object from falling due to such a collision. Also, even when the door is automatically closed, a warning sound is generated according to the automatic closing, preventing these accidents from occurring so that hands, fingers or objects are not caught by the door that is about to close. can do. Furthermore, when the door moves because it touches the door opening / closing key of the drawer-type heating cooker without consciousness, the person in the vicinity immediately recognizes the unexpected movement of the opening / closing door by a warning sound. You can also
Thus, according to this drawer-type heating cooker, when opening and closing the opening / closing door, not only those who operate, but also those who are around other drawer-type heating cooking appliances, against the movement of the opening / closing door It is possible to prevent a danger such as a collision caused by an opening / closing door or a pinching of a hand or a finger by a closing opening / closing door by prompting attention.
Furthermore, by generating a sound preferable to the user when opening and closing, there is an effect of eliminating an undesirable mechanical sound when opening and closing the door.
In addition, even when the opening / closing speed and the maximum opening distance are made variable, it is possible to cope with the use conditions of the user and the object to be heated by setting the warning sound. Furthermore, it is possible to grasp and recognize a change in the opening / closing of the door by setting the sound of the warning sound.

  Hereinafter, an embodiment of a drawer-type cooking device according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an embodiment of the drawer-type heating cooker according to the present invention in a state where the door is closed, and FIG. 2 is a state where the door of the drawer-type heating cooker shown in FIG. 1 is opened. FIG. 3 is a side sectional view of the drawer-type heating cooker shown in FIG.

  As shown in FIGS. 1 and 2, a drawer-type heating cooker (hereinafter simply referred to as “heating cooker”) includes a cooker body 1 and a drawer body 2 that can be pulled out from the cooker body 1. ing. Inside the cooker body 1 is formed a heating chamber into which the drawer body 2 for placing an object to be cooked can enter. The inside of the heating chamber is surrounded by the left, right, top, bottom, and back walls, but the front surface is formed in an opening for taking in and out the drawer body 2.

  The drawer body 2 is movably arranged in the cooker body 1 by a slide mechanism 4 to be described later so that the drawer body 2 can be pulled out from the heating chamber of the cooker body 1 to the outside in the direction indicated by the arrow or vice versa. Has been. The drawer body 2 includes an opening / closing door (hereinafter abbreviated as “door”) 2a for opening and closing the heating chamber, and a heating container 3 to which the door 2a is attached and for storing an object to be heated. ing. The heating container 3 includes a front plate attached to the door 2a, left and right side plates extending rearward from the left and right of the front plate, a rear plate connected to the side plate on the back (back) side, and a bottom plate connected to the side plate and the rear plate. The container opening part which can take in and out to-be-heated material in the upper part is formed. Although not shown in the figure, the microwave generator which is comprised from the magnetron which generate | occur | produces a microwave, and the waveguide which propagates the microwave which generate | occur | produced with the magnetron is arrange | positioned around the heating chamber. Has been. Microwaves generated by the magnetron propagate through the waveguide and are supplied from the power supply opening into the heating chamber.

In order to move the drawer body 2 within the cooker body 1, the heating cooker has slide mechanisms 4 and 4 disposed on the left and right outer sides of the heating container 3 and a slide mechanism 4 disposed on the bottom side (see FIG. 3). ). Although not shown in detail for each slide mechanism 4, each slide mechanism 4 is a telescopic mechanism composed of a slide rail that allows the movable rail to slide relative to the fixed rail. The drawer body 2 is movable between a fully opened position where the heating container 3 is completely pulled out of the heating chamber and a fully closed position where the heating container 3 is completely stored in the heating chamber. When the drawer body 2 occupies the fully closed position, since the door 2a closes the opening 10 of the heating chamber, the internal space of the heating chamber is sealed by the inner wall surface of the cooker body 1 and the drawer body 2.
Each slide mechanism 4 is provided in a passage box formed in the cooker main body 1 on each of the left and right sides and the bottom side of the heating chamber, the fixed rail is attached to the outside of the heating chamber in the passage box, and the movable rail is It is possible to appear in the passage box together with the drawer body 2. The drawer body 2 is supported by the cooker body 1 via the slide mechanisms 4 and can be stably pulled out from the heating chamber.
As shown in FIG. 3, in order to drive the drawer body 2 in the opening and closing direction, a rack 5 is fixed along the longitudinal direction of the movable rail in the slide mechanism 4 on the bottom side. A pinion 7 attached to the output shaft of the drive motor 6 is engaged with the rack 5.

  At least one of the slide mechanisms 4 is provided with a mechanism for operating the fully closed detection switch or the fully opened detection switch when the drawer body 2 is moved to the fully closed position and the fully opened position, respectively. For the fully closed detection, when the drawer body 2 is pushed from the open state to the fully closed position, the operation lever provided at the innermost position of the movable rail turns on the fully closed detection switch. Further, as shown in FIG. 3, in the passage box, a plurality of detection switches 8 (8 a to 8 e) including a fully closed and fully open detection switch are appropriately provided along the direction in which the drawer body 2 is pulled out. Arranged at intervals. In this way, the position of the drawer body 2 can be known by the operation of each detection switch 8 arranged according to the fully opened, intermediate, and fully closed positions of the drawer body 2, and the position information of the door 2a is included in this position information. Based on this, opening / closing control of the drawer body 2 is performed.

  When the drawer body 2 is pulled out, the operating lever is detached from the fully closed detection switch, and the fully closed detection switch is turned off. Therefore, even after cooking, even during cooking, when the drawer body 2 is opened, the power supply to the microwave generator is turned off, and generation of microwaves is disabled. The fully-closed detection switch can be used as a part of a switch that controls the oscillation and stop of the microwave. The user can set how the cooking device is actually heated by operating other operation switches. A main switch for starting cooking is separately provided. In addition, the operation switch (opening / closing door operation part) 12 for the operation operation of a heating cooker including opening / closing operation | movement of the door 2a can be arrange | positioned at the cooking appliance main body 1 (or door 2a).

  As described above, the drawer-type heating cooker can draw the drawer body 2 on which the object to be heated can be placed, together with the door 2a, with respect to the cooker body 1, and put the drawer body 2 into the heating chamber in the cooker body 1. It is a drawer type cooking device that can close the opening 10 of the heating chamber with the door 2a in the accommodated state. When the door 2 is opened and closed, a speaker 13 that emits a warning sound to be described later is provided on the cooker body 1 or the door 2a.

  FIG. 4 shows a control block diagram relating to driving of the door and the warning sound of the drawer-type heating cooker. The open / close door drive control unit 20 constitutes a part of the control unit of the drawer-type heating cooker. The open / close door drive control unit 20 issues a drive control signal to the open / close door drive unit (drive motor) 6, and the open / close door drive unit (motor) 6 is driven to open / close to the door 2 a through a transmission mechanism including a pinion 7 and a rack 5. A force is applied to automatically open or close the door 2a. The position and speed of the door 2a (detectable from the output rotation of the drive motor or the time required for detection between the positions) are always detected by the sensors 8a to 8e, and the detection data is fed back to the door drive control unit 20. Thus, the opening and closing of the door 2a is controlled at the set speed and position.

The warning sound is set by the sound setting unit 21. That is, setting data prepared in advance is read from the sound setting data unit 22, and the read data is displayed on the sound setting display unit 14 provided on the front surface of the cooker body 1, and the user watches the display. An alarm sound can be set by the sound setting input unit 23 in an interactive manner. The sound setting display part 14 is a display part of a general cooking device, and can be a screen that is displayed when the sound setting is selected from the menu screen.
The sound setting input unit 23 can be a touch panel on the sound setting display unit 14 or a remote control operation. The data set by the operation / selection in the sound setting input unit 23 is stored in the sound setting storage unit 24. As will be described later, the sound can be set by selecting or setting the pitch, tone color, volume, and the like.

  The sound setting is stored in the sound setting storage unit 24, and the sound control unit 25 performs output control on the speaker 13 by reading from the sound setting storage unit 24. In other words, it is determined how much time and how much sound is emitted with what pitch and timbre and how much volume. Since the detection data on the opening / closing position and speed of the door 2a is input not only to the opening / closing door drive control unit 20 but also to the sound control unit 25, the alarm sound generation control is in step with the opening / closing control of the door 2a. Done.

  For the sound setting, it is possible to select a warning sound stored in advance, and to select and set a method to be adopted from each of the changing methods for a change that enhances the warning performance. The set notification sound is stored in the sound setting storage unit 24, and the sound control unit 25 performs output control on the speaker 13 by reading from the sound setting storage unit 24. In other words, it is determined how much time and how much sound is emitted with what pitch and timbre and how much volume. Since the detection data on the opening / closing position and speed of the door 2a is input not only to the opening / closing door drive control unit 20 but also to the sound control unit 25, the alarm sound generation control is in step with the opening / closing control of the door 2a. Done.

  The user's education, taste, sensitivity, etc. will affect how the warning sound is received, so it is necessary to follow basic setting standards when selecting and setting the warning sound. When adopting a product, ask multiple users to try and listen to the invention of the present application, and select a warning sound that is easy to understand the relationship between the door opening / closing operation and the warning sound. It is preferable.

A method for setting the warning property of the warning sound and a method for setting the warning sound when the door is opened and closed will be described using a simple warning sound as an example. First, if it is decided to assign a rising melody as the warning sound when the door is opened and a downward melody as the warning sound when the door is closed, the general user can open and close the door in a relatively short time. The operation can be easily distinguished.
An example of an upward unit melody “Doremi remy sofa sofa sourasolaside” and an example of a downward unit melody “Dosila sila sofa sofa mifamired” are used as warning sounds. Here, if the “L” sound is 880 Hz, it is a common major C scale, and it rises / falls in 3 consecutive notes, then goes down / up, and finally goes up / down one octave to complete. Become a melody.

  If the duration of each sound that composes a unit melody is assumed to be constant at 0.5 seconds, for example, assuming that each sound is a quarter note, 120 quarter notes are generated per minute. The tempo of the metronome 120 (M.M. = 120), which is the tempo to be performed. Moreover, since each sound is continuously generated without any break, in terms of music, it becomes a legato expression. Further, the volume is constant, and volume changes such as gradual increase and decrease are not performed.

  Even if the unit melody ends, if the opening or closing operation has not ended, the unit melody is repeated.When the opening or closing operation ends, the final sound of the generated unit melody Will end after 1.0 second. In this case, the change in the opening distance is a change in the number of repetitions of the unit melody, and the unit melody itself is not changed.

The above rising sound warning sound is referred to as [A01] warning sound, and the falling sound warning sound is referred to as [B01] warning sound.
If the [A01] warning sound is generated during the opening operation and the [B01] warning sound is generated during the closing operation, the opening and closing operation can be easily started without observing the operation of the cooker. You can know when it is running and when it is finished.
In addition, when the unit melody is generated, the warning performance given to the user by the warning sound can be enhanced by performing the processes exemplified in the following a to d.
a. When the unit melody is repeated, the [A01a] warning sound and the [B01a] warning sound that shorten the duration of each sound are more strained than the [A01] warning sound and the [B01] warning sound. The alertness increases because you feel a sense.
b. [A01b] warning sound and [B01b] warning sound with increased volume when repeating the unit melody, the user is more nervous than [A01] warning sound and [B01] warning sound. Since it is memorized, the alertness increases.
c. Intermittent The duration of each sound of the unit melody is shortened, for example, [A01c] warning sound and [B01c] with 0.5 second generation time and 0.4 second generation time and 0.1 second silence time. In terms of music, the warning sound is expressed as a staccato, and compared with the [A01] warning sound and the [B01] warning sound, the user feels tense so that the warning performance is enhanced.
d. Impact The [A01d] warning sound and the [B01d] warning sound that increase the volume at the beginning of the sound of each unit melody, immediately decrease the volume, and approach the strike sound are [A01] warning sound and [B01] warning sound. Compared with, the user feels tense so that the warning is enhanced.

  The change by the items a to d described above can be performed not only independently but also by combining two or more items. For example, [A01abcd] warning sound and [B01abcd] warning sound obtained by simultaneously executing a, b, c, and d may be used.

Furthermore, when the three consecutive sounds of unit melody are set as [A02] warning sound and [B02] warning sound using the unit melody configured to rise / fall in the semitone scale instead of the whole scale, Compared with the A01] warning sound and the [B01] warning sound, the user feels nervous, so the warning performance is enhanced.
[A02] Warning sound and [B02] Warning sound are processed a to d, and [A02a] warning sound, [B02a] warning sound, and [A02d] warning sound, [B02d, which have high warning characteristics, respectively. ] A warning sound can be obtained.

  That is, according to the vertical selection in Table 1, N basic melodies from [A01], [B01] to [AN], [BN] are selected, and a method for changing the selected basic melody is selected. By selecting from methods such as a, b, c, and d, it is possible to set a warning sound having a distinction between opening / closing and a warning property with strength and selection according to the user's preference.

The setting and change of the above warning sound is described as a technical method, but in practice, the warning sound described in the form of a score is played with a computer-operable electronic keyboard instrument, and the above method is performed. If implemented as an expression, trial confirmation with high reproducibility is easy.
In particular, when playing a musical score, the unit melody initially set in C major is transposed to D major, E-flat major, etc., and it is easy to change the frequency stepwise by dividing one octave into 12 levels. is there. In the pitch setting, when the pitch is continuously changed, there may be discomfort depending on the user's sense of hearing, but if the pitch change can be heard as a musical transposition, it will not cause discomfort. The pitch can be set.

  The above changes and changes in alertness exemplify a simple setting method based on a melody using an extremely simple scale, but it is easy to distinguish between opening and closing, and a warning. If it is selected after trial confirmation that it is easy to distinguish the sex difference, a more complicated and free melody and processing method can be adopted after trial and confirmation.

  An example of the sound setting operation in the sound setting display unit 14 is shown in FIG. In the pull-out distance setting item, set the pull-out distance (preferably defined as a section, but not limited to this) by opening and closing from fully closed to fully open, and the pitch setting, tone setting, and volume according to each pull-out distance Each setting is possible. In the rhythm setting, it is possible to select a rhythm element having a certain rhythm pattern (repeatedly played with a short one) or a single note repetition.

In the pitch setting, it is possible to select a scale, a sound frequency level, and the like. In the tone color setting, the type of instrument sound such as a whistle or the type of synthesized sound can be selected. Furthermore, in the volume setting, the volume of the warning sound and the gradual increase or decrease of the volume can be set.
In FIG. 5, the user can select whether to listen to the warning sound after changing the sound setting and confirm the sound setting change, or to cancel the sound setting change and maintain the previous sound setting.

  FIG. 6 exemplifies actual warning sound modes (a) when the door is automatically opened and (b) when the door is automatically closed. As shown in FIG. 6, the sound setting of the warning sound depends on whether the current opening / closing door operation is an opening operation or a closing operation, and in each operation, depending on the current opening distance L. Can be determined. That is, as shown in FIG. 6A, at the time of automatic opening, the pitch can be increased as the door opens and the opening / closing distance L increases. The maximum value of the pitch can be increased as the maximum opening distance Lmax is increased. On the other hand, as shown in FIG. 6B, during automatic closing, the pitch can be increased as the door is closed and the opening / closing distance L is reduced. Also in this case, the pitch can be increased as the maximum opening distance Lmax is larger and the closer to full closure.

Furthermore, this sound setting can be determined according to the opening / closing speed of the door, the maximum opening distance, the use conditions of the user or the characteristics of the object to be heated. For example, the faster the opening / closing speed of the door, the higher the maximum opening distance. It is preferable to perform sound setting with a higher warning property as the heating heat amount and the size of the object to be heated are longer.
Alternatively, when a heated object is heated in a stationary state with high-frequency heating in a drawer-type cooking device, boiling does not start even when the temperature of the object exceeds the boiling point, and boiling starts when the door opens and closes. Since the phenomenon is likely to occur, it is preferable to perform a sound setting with a high warning property at the time of opening compared to the sound setting at the time of closing of the door.
Such a sound setting can be set to be easy to hear as a warning sound and easily distinguishable from the difference of the warning sound due to the operation when the user listens to and confirms such a sound setting.
