[0028] The top plate 3 is a placement portion on which a container can be placed. The container is an example of a heating object heated by one of the heating coils 4A to 4C. The top plate 3 is arranged on the upper surface of the housing 2. The top plate 3 is made of a material such as glass that can transmit the magnetic field generated by the heating coils 4A to 4C.

[0029] The heating coils 4A to 4C are an example of a heating unit that heats a container. Hereinafter, when there is no need to distinguish between the heating coils 4A to 4C, they are collectively referred to as the heating coil 4. The heating coil 4 is arranged below the top plate 3. The heating coil 4 generates an induced magnetic field when a high-frequency current is supplied to the heating coil 4. The heating coil 4 heats the bottom surface of the container arranged on the top plate 3 through the magnetic field, thereby being able to heat the cooking object accommodated in the container. In the present embodiment, the heating unit performs induction heating by the heating coils 4A to 4C respectively, but is not limited to this. For example, at least one of the heating units may also be configured to heat the heating object placed above the heating device through other heating devices such as a radiation heater and a halogen heater.

[0030] like Figure 1 As shown, the cooking device of this embodiment includes three heating coils 4A to 4C, and can heat three heating objects at the same time.

[0031] The heating unit 5 is a so-called grill heating unit. The heating unit 5 is configured to be pulled out from the front of the housing 2. The heating unit 5 is configured to be pulled out from the housing 2 so that a user can take in and out the heating unit 5.

[0032] The top surface operation panel 6 is provided on the top plate 3. The top surface operation panel 6 is an example of an input / output interface device. The user of the heating cooker 1 can use the heating cooker 1 by operating the top surface operation panel 6. The top surface operation panel 6 includes a power operation unit 9, operation units 10A to 10C, and display units 11A to 11C. The details of the power operation unit 9, the operation units 10A to 10C, and the display units 11A to 11C will be described later.

[0033] The side operation panel 7 is provided on the front surface of the housing 2. The side operation panel 7 is an example of an input / output interface device. The side operation panel 7 is configured to be accommodated in the housing 2. The side operation panel 7 includes a side operation unit 12 and a side display unit 13. The details of the side operation unit 12 and the side display unit 13 will be described later.

[0034] The control device 8 is, for example, a computer, and includes a calculation circuit and a storage device. The control device 8 is an example of a control unit of the heating cooker 1 of the present disclosure.

[0035] The calculation circuit controls the overall operation of the cooking device 1. The calculation circuit may be a system in which hardware resources and software cooperate to realize a predetermined function, or a system in which a specially designed hardware circuit is used to realize a predetermined function.

[0036] As an example of the former, the operation circuit includes a general-purpose processor such as a CPU or MPU that implements a specified process or function by executing a program. The operation circuit is configured to communicate with a storage device. The operation circuit implements various functions in the control device 8 by reading and executing an operation program stored in the storage device. As an example of the latter, the operation circuit includes an FPGA and an ASIC. As can be seen from the above, the operation circuit can be implemented using semiconductor integrated circuits such as a CPU, an MPU, a GPU, an FPGA, a DSP, and an ASIC.

[0037] The storage device is a storage medium capable of storing various information. The information includes programs and data. For example, the storage device stores operation programs for implementing various functions of the present embodiment. The storage device is implemented, for example, by DRAM, SRAM or flash memory, SSD and other volatile or non-volatile semiconductor memory, HDD and other storage devices, or a suitable combination thereof.

[0038] Figure 2 It is a block diagram showing the connection between the above-mentioned components and the control device 8.

[0039] The control device 8 is electrically connected directly or indirectly to the power supply operation unit 9, the operation units 10A to 10C, the display units 11A to 11C, the side operation unit 12, the side display unit 13, and the inverter circuits 14A to 14C. Hereinafter, when it is not necessary to distinguish between the operation units 10A to 10C, they are collectively referred to as the operation unit 10. Hereinafter, when it is not necessary to distinguish between the display units 11A to 11C, they are collectively referred to as the display unit 11.

[0040] The control device 8 controls the operation of the heating coils 4A to 4C via the inverter circuits 14A to 14C.

[0041] Figure 3 FIG. 6 is a schematic diagram of the upper surface operation panel 6 of the heating cooker 1 according to the present embodiment. Figure 3 As shown, the top surface operation panel 6 includes a power operation unit 9, operation units 10A to 10C, and display units 11A to 11C.

[0042] The power operation unit 9 has a function of accepting an operation from a user to switch the power of the cooking device 1 on and off. An example of the power operation unit 9 is a switch. When the user presses the power operation unit 9, the control device 8 switches the power of the cooking device 1 on and off.

[0043] The operation unit 10A has a function of accepting an operation from a user to switch the action of the heating coil 4A. An example of the operation unit 10A is a switch. In the present embodiment, the operation unit 10A has a first selection button 15A and a second selection button 16A. In the present embodiment, the operation unit 10A also has a first button 17A and a second button 18A, but is not limited thereto. The first button 17A and the second button 18A may also be provided separately from the operation unit 10A.

[0044] The display unit 11A has a function of displaying in accordance with the operation of the operation unit 10A by the user. An example of the display unit 11A is a display. The display unit 11A may also display in accordance with the operation other than the operation of the operation unit 10A by the user, such as a display showing the state of the heating cooker 1. The display unit 11A can display, for example, the heating power of the heating coil 4A, the remaining time for heating, and the like.

[0045] The display unit 11A of the heating cooker 1 of the present embodiment has an area capable of displaying "heating", "frying", "grilling", and "boiling water". The control device 8 can light up the words "heating" and the like in the display unit 11A, for example, by lighting up an LED disposed inside the display unit 11A. In addition, the control device 8 is configured to turn off the words "heating" and the like displayed in the display unit 11A by turning off the LED. In addition, in the display unit 11A, "boiling water" is indicated by a kettle mark. In the present embodiment, lighting up is an example of the first display state. Turning off is an example of the second display state.

[0046] The first selection button 15A and the second selection button 16A are buttons that can accept user operations to change the operation mode of the heating coil 4A. In the present embodiment, the control device 8 has a plurality of operation modes corresponding to a plurality of cooking menus with respect to the heating coil 4A. In the present embodiment, the plurality of cooking menus include "heating", "frying", "grilling", and "boiling water". The cooking menu may also include menus other than the above-mentioned menus.

[0047] When the control device 8 detects that the first selection button 15A is pressed, the control device 8 first switches the "heating" area to light and dark alternately at a predetermined cycle to flash the display unit 11A. After that, the control device 8 switches the flashing area in the order of "heating", "frying", "grilling", "boiling water", and "heating" each time the control device 8 detects that the first selection button 15A is pressed. When the control device 8 detects that the second selection button 16 is pressed, the control device 8 switches the flashing area in the reverse order of the case where the first selection button 15A is pressed.

[0048] The first button 17A indicates a button for accepting a user's predetermined operation on the heating coil 4A. For example, the first button 17A indicates a button that can make the heating coil 4A operational. When the control device 8 detects that the user has pressed the first button 17A, the display of the display unit 11A changes to a state that can accept operations related to the heating coil 4A.

[0049] When detecting that first button 17A is pressed while any of the above-mentioned cooking menus is selected, ie, while the "heating" area or the like is flashing, control device 8 determines to operate heating coil 4A in the operation mode corresponding to the selected cooking menu.

[0050] The second button 18A is a button for accepting an operation for setting a timer for automatically stopping the heating coil 4A. For example, the user can set a timer for the heating coil 4A by pressing the second button 18A after the heating coil 4A starts operating.

[0051] The operation unit 10B and the display unit 11B, the operation unit 10C and the display unit 11C, and the operation unit 10A and the display unit 11A are configured similarly. The operation units 10A to 10C are examples of the first operation unit and the second operation unit, respectively. The display units 11A to 11C are examples of the first display unit and the second display unit, respectively.

[0052] In addition, in the present embodiment, the control device 8 has operation modes corresponding to "heating" and "cooking" respectively for the heating coil 4B. For the heating coil 4C, the control device 8 has the same operation mode as the heating coil 4A. If it is detected that the first selection button 15B or the second selection button 16B in the operation unit 10B is pressed, the control device 8 switches the flashing area in the display unit 11B between "heating" and "cooking".

[0053] In this way, the control device 8 can switch at least a partial area of ​​the display unit 11 to a plurality of display states alternately at a predetermined cycle.

[0054] In the present embodiment, in the case where there are areas where two or more of the display units 11A to 11C flash, the control device 8 is configured to synchronize the flashing. For example, in the case where the user selects cooking menus for the heating coil 4A and the heating coil 4C, respectively, the control device 8 can flash "heating" in the display unit 11A and flash "frying" in the display unit 11C. Furthermore, the control device 8 can flash the "heating" area of ​​the display unit 11A and the "frying" area of ​​the display unit 11C in a synchronized manner. With such a structure, even if there are flashing displays in the areas of two of the display units 11A to 11C, the flashing displays will not flash inconsistently, but will flash synchronously. By performing control in this way, the appearance quality of the heating cooker 1 can be improved.

[0055] Figure 4 1 is a schematic diagram of the side operation panel 7 of the heating cooker 1 according to the present embodiment. Figure 4 As shown, the side operating panel 7 includes a side operating portion 12 and a side display portion 13 .

[0056] The side operating unit 12 has a function of accepting an operation from a user to switch the operation of the heating unit 5. An example of the side operating unit 12 is a switch. By pressing the switch of the side operating unit 12, the user can operate the power on and off of the heating unit 5, switch the cooking menu when the heating unit 5 is operated, etc.

[0057] The side display unit 13 has a function of displaying information corresponding to the user's operation on the side operating unit 12. An example of the side display unit 13 is a display. The side display unit 13 may also display information corresponding to operations other than the user's operation on the side operating unit 12, such as displaying the state of the cooking device 1.

[0058] In the cooking device 1 of this embodiment, the control device 8 operates the heating unit 5 according to the user's operation of the side operating unit 12. When the heating unit 5 is operated, the control device 8 changes the display of the side display unit 13 to inform the user that the heating unit 5 is in operation and its operating state.

[0059] In addition, in the heating cooker 1 of the present embodiment, when the heating unit 5 is operated, the control device 8 causes the heating unit 5 to Figure 3 The specified area 19 (hereinafter also appropriately referred to as "grilling area") of the upper surface operation panel 6 is lit. In the present embodiment, the grilling area 19 is represented by a fish mark. The control device 8 lights up the grilling area 19 when the heating unit 5 is in operation, thereby being able to notify the user that the heating unit 5 is in operation.

[0060] Thus, according to the heating cooker 1 of this embodiment, the user can visually confirm and understand whether the heating unit 5 is in operation without observing the side operating portion 12 provided on the side of the housing 2 and retractable in the housing 2. Therefore, according to the heating cooker 1, the convenience of the user can be improved.

[0061] The control device 8 may also light up the grilling area 19 of the upper surface operation panel 6 when the heating unit 5 is not in operation. For example, the control device 8 may light up the grilling area 19 when the temperature in the box of the heating unit 5 is high. With such a structure, even after the operation of the heating unit 5 is terminated, the heating cooker 1 can prompt the user to pay attention when the temperature in the box is high.

[0062] [action]

[0063] Hereinafter, a switching process of switching the flashing of the menu displayed on the display unit 11A will be described. The display unit 11A is an example. The following description can also be applied to the switching process of the display state of the display unit 11B and / or the display unit 11C.

[0064] Figure 5 : is a graph showing an example of transition of the flashing area of ​​the display unit 11A of the heating cooker 1 according to the present embodiment. Figure 5 In the graphs shown, graph (a) shows the display status of the display unit 11B. Graph (b) shows the display status of the "heating" area in the display unit 11A. Graph (c) shows the display status of the "frying" area in the display unit 11A. Graph (d) shows the display status of the "grilling" area in the display unit 11A. Graph (e) shows the display status of the "boiling water" area in the display unit 11A. Figure 5 In the figure, the horizontal axis represents time. In each graph, "ON" represents a lit state, and "OFF" represents an extinguished state. In addition, in the present disclosure, the situation where the control device 8 causes a specified area of ​​the display unit 11 to flash is also referred to as causing a specified menu to flash.

[0065] Figure 5 Each of the graphs shown indicates that the display state of at least a part of the display section 11A and the display section 11B is a flashing state, that is, the display state is alternately switched between on and off at a predetermined cycle. In addition, each of the graphs indicates that the display state of the area other than the flashing area in the display section 11A and the display section 11B is an off state. Thus, in the heating cooker 1 of the present embodiment, the control device 8 switches at least a part of the display section 11 to be alternately switched between on and off at a predetermined cycle.

[0066] like Figure 5 As shown, in this embodiment, the control device 8 can control the switching between lighting and extinguishing so that the display state of the display unit 11A is synchronized with the display state of the display unit 11B. The control device 8 can also control the display state of the display unit 11C in the same manner.

[0067] like Figure 5 As shown in the diagram (a) of FIG. 1 , the control device 8 switches the “heating” area in the display unit 11B, for example, to light up and turn off and flash at a predetermined cycle. In the present embodiment, the predetermined cycle is configured such that the lighting period is the same as the off period, but is not limited to this. Alternatively, the lighting period may have a predetermined duty ratio relative to the predetermined cycle.

[0068] exist Figure 5In the example shown, the first selection button 15A of the operation unit 10A is pressed at time t1, t2, and t3, respectively. As shown in the graph (b), the control device 8 switches the "heating" area of ​​the display unit 11A to light and turn off at a predetermined cycle to flash during the period from time t0 to time t1.

[0069] As shown in the graphs (b) and (c), if the first selection button 15A of the operation unit 10A is pressed at time t1, the control device 8 ends the flashing of the "heating" area and starts flashing the "frying" area. Time t1 corresponds to the lighting period in the prescribed cycle of flashing. Therefore, the control device 8 ends the lighting of the "heating" area and lights up the "frying" area. After that, the control device 8 flashes the "frying" area of ​​the display unit 11A in synchronization with the flashing of the display unit 11B according to the prescribed cycle. In this way, if the control device 8 detects that the first selection button 15A of the operation unit 10A is pressed, it can change the flashing area in the display unit 11A to another area.

[0070] As shown in the graphs (c) and (d), if the first selection button 15A of the operating unit 10A is pressed at time t2, the control device 8 ends the flashing of the "frying" area and starts the flashing of the "grilling" area. The time t2 corresponds to the period of extinguishing in the prescribed cycle of flashing. In response to the pressing of the operating unit 10A, the control device 8 keeps the "frying" area extinguished and lights up the "grilling" area. Then, the control device 8 keeps the "grilling" area lit from time t2 to the next lighting period in the prescribed cycle. After the start of the next lighting period, the control device 8 flashes the "grilling" area of ​​the display unit 11A in synchronization with the flashing of the display unit 11B according to the prescribed cycle.

[0071] That is, when control device 8 of the present embodiment detects that operation portion 10A is pressed, even if the timing of the pressing is during the off period in a predetermined cycle, it first lights up the newly selected menu and then starts blinking the menu.

[0072] By such control, when the user presses the operation unit 10A to switch the selected menu during the extinguishing period, the newly selected menu is first lit and then starts to flash. Therefore, the user using the heating cooker 1 can easily visually confirm and understand that the pressing of the operation unit 10A is accepted. In addition, the user can easily visually confirm and understand the menu switched by pressing the operation unit 10A. In addition, the control device 8 makes the display unit 11A and the display unit 11B flash synchronously from the next lighting period in the prescribed cycle, so that the appearance quality of the heating cooker 1 can be improved.

[0073] As shown in the graphs (d) and (e), when the first selection button 15A of the operation unit 10A is pressed at time t3, the control device 8 stops flashing the "grill" area and starts flashing the "boil water" area. Time t3 corresponds to the lighting period in the prescribed flashing cycle. Therefore, the control device 8 stops lighting the "grill" area and lights the "boil water" area. Figure 5 In the example shown, the period T between the time t3 and the end period of the lighting period in the prescribed cycle is shorter than the prescribed time. Therefore, the control device 8 maintains the lighting of the "boil water" area in the subsequent extinguishing period in addition to the lighting period including the time t3 in the prescribed cycle regardless of the prescribed cycle. After the start period of the next lighting period after the lighting period, the control device 8 flashes the "boil water" area of ​​the display unit 11A in synchronization with the flashing of the display unit 11B according to the prescribed cycle. In addition, the prescribed time is a predetermined period, for example, it can be a period of 0.5 seconds.

[0074] That is, the control device 8 of this embodiment maintains the lighting of the newly selected menu during the next off period when the operation unit 10A is pressed during the lighting period of the specified cycle and the time between the pressing timing and the end of the lighting period is short. For example, the control device 8 maintains the lighting of the newly selected menu during the next off period when the above period T is less than the specified time.

[0075] By such control, even if the operation unit 10A is pressed at a timing that is switched to off immediately after being lit in a predetermined cycle, the newly selected menu is also lit for a certain period. Therefore, the user who uses the heating cooker 1 can easily visually confirm and understand the menu switched by pressing the operation unit 10A. In addition, the control device 8 makes the display unit 11A and the display unit 11B flash synchronously from the next lighting period in the predetermined cycle, thereby improving the appearance quality of the heating cooker 1.

[0076] In this embodiment, the control device 8 extends the lighting of the newly selected menu when it is determined that the above period T is less than the specified time. That is, the control device 8 extends the lighting of the newly selected menu when the time between the timing when the operation unit 10A is pressed and the end period of the lighting period in the specified cycle is less than the specified time.

[0077] Without being limited to the above structure, the control device 8 may also extend the lighting of the newly selected menu when it is determined that the above period T is less than a specified ratio of the lighting period T0 in the specified cycle. The specified ratio may be, for example, 50%. Regardless of which of the specified time and the specified ratio is used for judgment, it is uniformly expressed in the present disclosure as follows: when the remaining time of the lighting period is less than the specified time at the moment when the operation of the operating unit 10A is performed, the control device 8 maintains the display unit 11A in the lighting state until the next lighting period. The control device 8 may also switch to the off state according to the specified cycle when the remaining time of the lighting period is longer than the specified time at the moment when the operation of the operating unit 10A is performed.

[0078] In addition, the control device 8 can determine the period T by finding the period between the timing when the operation unit 10A is pressed and the end period of the lighting period including the timing in the prescribed cycle. In addition, the control device 8 can determine the period T by subtracting the period between the timing and the start period of the lighting period including the timing in the prescribed cycle from the lighting period. Since these are similar, they are uniformly expressed in the present disclosure as follows: the control device 8 determines the period T by finding the period between the timing and the end period of the lighting period including the timing in the prescribed cycle.

[0079] exist Figure 5 In the example shown, the display unit 11A and the display unit 11B flash, so the control device 8 operates in a manner that synchronizes the flashing of each. Here, for example, when the user presses the first button of the operation unit 10B to determine the cooking menu of the display unit 11B, the control device 8 stops the flashing of the display unit 11B and changes the display state of the display unit 11B to light up or turn off. In this case, the control device 8 does not need to synchronize the flashing of the display unit 11A with the display unit 11B after the flashing ends.

[0080] Therefore, when the flashing of the display unit 11B ends, Figure 5 In the case where the display 11A is changed from the diagram (c) to the diagram (d), the control device 8 may change the start time of the lighting period of the predetermined cycle of the flashing to the timing of the pressing, that is, time t2. That is, the control device 8 may light up the next menu and change the start time of the lighting period of the predetermined cycle related to the flashing of the menu to the timing of the pressing when the operation unit 10A is pressed during the extinguishing period, when there is no object synchronized with the flashing of the display unit 11A.

[0081] The display state (ie, lighting or extinguishing) of the display unit 11B after the flashing is completed is an example of the third display state. The third display state may be the same display state as the first display state or the second display state.

[0082] In addition, the control device 8 may also change the start time of the lighting period of the predetermined cycle of the flickering after the transition to time t3 when the flickering of the display unit 11B ends when the graph (d) changes to the graph (e). That is, the control device 8 may also set the start time of the lighting period of the predetermined cycle related to the flickering to the timing of the pressing when the operation unit 10A is pressed during the lighting period and the remaining time of the lighting period is less than the predetermined time when there is no object synchronized with the flickering of the display unit 11A. In addition, when the operation unit 10A is pressed when there is no object synchronized with the flickering of the display unit 11A, the control device 8 may set the start time of the lighting period of the predetermined cycle related to the flickering of the display unit 11A to the timing of the pressing regardless of the predetermined cycle of the flickering.

[0083] Figure 6 This is a flowchart showing the switching process of the control device 8 of the heating cooker 1 according to the present embodiment.

[0084] At the beginning of the switching process, Figure 5 As shown in the example, the control device 8 synchronizes the flashing of the display unit 11A with the flashing of the display unit 11B. That is, the control device 8 flashes the area corresponding to the menu being selected for the heating coil 4A in the display unit 11A and the area corresponding to the menu being selected for the heating coil 4B in the display unit 11B.

[0085] First, the control device 8 determines whether pressing of the first button 17A is detected ( S11 ).

[0086] If it is not detected (S11: No), the control device 8 determines whether the pressing of the first selection button 15A or the second selection button 16A is detected (S12). If the pressing of the first selection button 15A or the second selection button 16A is not detected (S12: No), the control device 8 returns to step S11. Therefore, if the control device 8 does not detect the pressing of any of the first button 17A, the first selection button 15A, and the second selection button 16A, it repeats the determination of steps S11 and S12.

[0087] When the pressing of the operation unit 10A (ie, the first selection button 15A or the second selection button 16A) is detected (S12: YES), the control device 8 determines whether the operation unit 10A is pressed during the extinguishing period of the predetermined cycle of the flashing of the selected menu (S13).

[0088] When the operation unit 10A is pressed at a time when the flashing is off during a predetermined period (S13: Yes), the control device 8 stops flashing the currently selected menu, lights up the next menu, and starts flashing the next menu (S14). For example, when the first selection button 15A is pressed while the "heating" area is flashing on the display unit 11A, the control device 8 turns off "heating" and flashes "frying". At this time, the control device 8 first turns on "frying" regardless of the flashing period.

[0089] Next, the control device 8 determines whether the other display unit (that is, at least one of the display units 11B and 11C in the example of this flowchart) is blinking (S15).

[0090] When the other display units are flashing (S15: Yes), the control device 8 continues to light up the next menu in the display unit 11A during the first period of extinguishing after switching the flashing menu (S16). That is, the control device 8 extends the lighting of the display unit 11A for a predetermined period until the next lighting period. After that, the control device 8 switches the next menu in the display unit 11A to alternately light up and turn off in a predetermined period to flash in a manner that synchronizes the flashing of the display unit 11A with the flashing of the other display units (S17). Then, the control device 8 returns to step S11 to determine whether the pressing of the first button 17A is detected.

[0091] When the control device 8 determines that the pressing of the first button 17A is detected (S11: Yes), the switching process ends. In this case, the control device 8 executes a prescribed process corresponding to the selected menu when the first button 17A is pressed. For example, when the selected menu is "heating", the control device 8 operates the heating coil 4A in the action mode corresponding to "heating".

[0092] When the other display unit is not flashing (S15: No), the control device 8 changes the start time of the prescribed cycle to the timing of the pressing of the operation unit 10A regardless of the flashing cycle before the pressing of the operation unit 10A (S18). Then, the control device 8 causes the next menu to flash alternately by turning on and off at the prescribed cycle after the start time is changed (S17). The flashing of the other display unit can be ended, for example, when the first button corresponding to the other display unit is pressed after the switching process starts.

[0093] When the timing of pressing the operation unit 10A is not during the off period of the predetermined cycle of blinking (S13: No), the control device 8 ends blinking of the currently selected menu and blinks the next menu (S19).

[0094] Next, the control device 8 determines whether the remaining time of the lighting period in the predetermined cycle of flashing is less than the predetermined time (S20). In other words, the control device 8 determines whether the time between the pressing timing and the end of the lighting period in the predetermined cycle of flashing is less than the predetermined time.

[0095] If the remaining time is not less than the specified time (S20: No), the control device 8 switches the next menu to alternately light and turn off to flash at a specified cycle (S17). For example, the control device 8 can flash the next menu in accordance with the specified cycle of the menu flashing before the operation unit 10A is pressed.

[0096] When the remaining time is less than the predetermined time ( S20 : ​​YES), the control device 8 determines whether the other display units are flashing ( S21 ).

[0097] When the other display unit is flashing (S21: Yes), the control device 8 continues to light up the next menu in the display unit 11A during the first period of extinguishing after the flashing menu is switched (S22). That is, the control device 8 extends the lighting of the display unit 11A for a predetermined period until the next lighting period. Then, step S17 is executed.

[0098] When the other display units are not blinking ( S21 : NO), the control device 8 executes step S18 .

[0099] As described above, the control device 8 of the cooking device 1 of the present embodiment executes the switching process in response to the pressing of the operation unit 10 by the user, and switches the menu being selected and flashing on the display unit 11 .

[0100] [Effect]

[0101] According to the heating cooker 1 of the embodiment, the following effects can be achieved.

[0102] The heating cooker 1 of the embodiment of the present disclosure includes a top plate 3, a heating unit 4 provided below the top plate 3, a first operating unit 10 and a second operating unit 10, a first display unit 11 and a second display unit 11, and a control unit 8. The first operating unit 10 and the second operating unit 10 are configured to receive an operation for performing heating cooking using the heating unit 4. The first display unit 11 is configured to perform a display corresponding to the operation of the first operating unit 10. The second display unit 11 is configured to perform a display corresponding to the operation of the second operating unit 10. The first display unit 11 and the second display unit 11 respectively have a first display state and a second display state different from the first display state. The control unit 8 is configured to alternately switch the first display unit 11 between the first display state and the second display state at a predetermined cycle, and alternately switch the second display unit 11 between the first display state and the second display state at a predetermined cycle. The control unit 8 is configured to, if the first operating unit 10 receives an operation when the display states of the first display unit 11 and the second display unit 11 are synchronized, set the first display unit 11 to the first display state regardless of the predetermined cycle.

[0103] According to such a structure, when the user operates the first operating unit 10, even if the first display unit 11 is controlled to be synchronized with the second display unit 11, the control unit 8 of the heating cooker 1 switches the display state of the first display unit 11 regardless of the prescribed cycle of switching the display state. The user can visually confirm that the operation of the first operating unit 10 is accepted. The user can understand that the operation of the first operating unit 10 is accepted. Therefore, according to the heating cooker 1, the operability can be improved.

[0104] In addition, in the heating cooker 1, the control unit 8 is configured to make the first display unit 11 the first display state if the first operating unit 10 accepts an operation during the second display state. According to such a structure, even if the operating unit 10 is pressed during the second display state to switch the selected menu, the display state of the newly selected menu starts from the first state. Therefore, the user can easily visually confirm and understand that the pressing of the operating unit 10 is accepted. Furthermore, the display state of the newly selected menu changes from the second display state or other display states to the first display state, so the user can easily visually confirm and understand the menu switched by pressing the operating unit 10.

[0105] In addition, in the heating cooker 1, the control unit 8 is configured to maintain the first display unit 11 in the first display state until the next first display state in the predetermined cycle. According to such a structure, even if the selected menu is switched during the second display state and the newly selected menu is changed to the first display state, the menu will not be immediately switched to the second display state, but will be maintained in the first display state according to the predetermined cycle. Therefore, the user can easily visually confirm and understand the menu switched by pressing the operation unit 10.

[0106] In addition, in the heating cooker 1, the control unit 8 is configured to change the second display unit 11 to the third display state after the switching between the first display state and the second display state performed in a predetermined cycle is completed. The control unit 8 is configured to change the first display unit 11 to the first display state if the first operating unit 10 accepts an operation after the second display unit 11 is changed to the third display state, and change the start time of the period of the first display state in the predetermined cycle to the timing of the operation. According to such a structure, the control device 8 does not need to synchronize the switching of the display state in the first display unit 11 with the second display unit 11. Therefore, the control device 8 can set the timing of switching the first display unit 11 to the first display state according to the operation of the first operating unit 10 as the start time of the period of the first display state, and can stably light up the display unit 11 for a certain period. Therefore, the user can easily visually confirm and grasp the menu switched by pressing the operating unit 10.

[0107] In addition, in the heating cooker 1, the control unit 8 is configured to maintain the first display unit 11 in the first display state until the next first display state when the remaining time of the first display state at the moment of the operation is less than the prescribed time if the first operating unit 10 accepts an operation during the first display state. The control unit 8 is configured to change the first display unit 11 to the second display state according to a prescribed cycle when the remaining time of the first display state at the moment of the operation is more than the prescribed time. According to such a structure, even if the first operating unit 10 is pressed at a timing such that it is immediately switched to off after being lit according to a prescribed cycle, the newly selected menu is also lit for a certain period. Therefore, the user can easily visually confirm and grasp the menu switched by pressing the operating unit 10.

[0108] In addition, in the heating cooker 1, the first display state is lit, and the second display state is extinguished. According to such a structure, the user can judge that the menu lit by pressing the operating unit 10 is a newly selected menu. Therefore, the user can easily visually confirm and grasp the menu switched by pressing the operating unit 10.

[0109] (Other embodiments)

[0110] In the above embodiment, lighting is taken as an example of the first display state and extinguishing is taken as an example of the second display state, but the present invention is not limited thereto. The first display state may be extinguishing, and the second display state may be lighting. In this case, the control device 8 can control the menu being selected by the user to flash in each display unit 11, and to light up the menu that is not being selected. In addition, if the control device 8 detects that the operation unit 10A is pressed, the control device 8 can control the flashing of the selected menu to end and the next menu to start flashing from extinguishing.

[0111] In addition, the display state of each display unit 11 is not limited to the two states of lighting and extinguishing, and may have more than three states. For example, the control device 8 may also light up a menu that is not selected darker than the normal lighting (hereinafter, appropriately referred to as "dark lighting"). That is, the control device 8 may also switch the selected menu between lighting and extinguishing in the display unit 11 to flash, so that the menu that is not selected becomes darker. That is, for example, the first display state may be lighting, the second display state may be extinguished, and the third display state may be dark lighting. In addition, the control device 8 may also periodically switch the selected menu to lighting and dark lighting, so that the menu that is not selected is extinguished. The control device 8 may also periodically switch the selected menu in the display unit 11A to the three display states of lighting, dark lighting, and extinguishing.

[0112] The display states that can be taken by each display unit 11 are not limited to states determined by differences in brightness, but can also be states determined by differences in color. For example, the control device 8 can also be controlled to periodically switch the menu being selected in the display unit 11 to red and green lighting, and to light up the menu that is not being selected in yellow.

[0113] In the above embodiment, the control device 8 switches the display state of the "heating" area, etc. by turning on and off the LED provided in the display unit 11, but the present invention is not limited thereto. For example, when the display unit 11 is a liquid crystal display, the control device 8 may also switch the display state by displaying and deleting the word "heating" on the display unit 11.
