[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and description thereof will not be repeated.

[0010] A cooking device 100 according to the present embodiment will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a front view of the cooking device 100 according to the present embodiment. Fig. 2 is a functional block diagram of the cooking device 100 according to the present embodiment.

[0011] As shown in FIG. 1, the cooking device 100 includes a housing 10, a cooking chamber 20, an opening / closing door 30, a touch panel display 41, operation buttons 46, 47, a heating section 50, a control section 60, a memory section 70, and various sensors 80.

[0012] The housing 10 has, for example, a substantially rectangular parallelepiped shape with an open front. The cooking chamber 20 is provided inside the housing 10. In the cooking chamber 20, an object to be cooked (not shown) is placed.

[0013] The opening / closing door 30 shown in FIG. 1 is a vertical-opening door. Specifically, the lower side of the housing 10 is set as a horizontal axis, and the opening / closing door 30 is attached to the housing 10 so as to be rotatable around this horizontal axis. The opening / closing door 30 also has a handle 34. The handle 34 is disposed on the upper part of the opening / closing door 30. However, the opening / closing door 30 of this embodiment is not limited to a vertical-opening door. For example, the opening / closing door 30 may be a horizontal-opening door that is rotatable around a vertical axis set as the left side side of the housing 10.

[0014] The heating unit 50 heats the food placed in the cooking chamber 20. For example, a magnetron is used for the heating unit 50. The magnetron supplies microwaves to the cooking chamber 20. The magnetron is an example of a microwave generator. The heating unit 50 may be a heater that generates heat and roasts the food. The cooking device 100 according to this embodiment may be either a microwave oven having a magnetron as the heating unit 50 or an oven having a heater as the heating unit 50, or may be an oven range equipped with both the functions of a microwave oven and an oven.

[0015] The touch panel display 41, the operation buttons 46, and the operation buttons 47 are disposed on the front side of the housing 10. The touch panel display 41 has a backlight, and displays a screen relating to cooking of the cooking target by turning on the backlight. The touch panel display 41 also accepts a touch operation (tap) by the user on the displayed screen. The touch panel display 41 is a liquid crystal display or an organic EL display provided with a touch sensor that detects the touch operation (tap). The touch sensor is, for example, a capacitive touch sensor. When the touch sensor detects a tap, it outputs a signal indicating the detection result to the control unit 60. In this embodiment, the touch panel display 41 is an example of a display unit and an example of an operation unit.

[0016] Note that the cooking device 100 of the present embodiment may not be the touch panel display 41, but may be a liquid crystal display or an organic EL display that only has a function of displaying a screen related to cooking of the cooking target.

[0017] The operation buttons 46 and 47 receive user operations. For example, physical buttons or pressure-sensitive touch panel switches are used for the operation buttons 46 and 47. For example, the operation buttons 46 and 47 are assigned with specific functions of confirm and cancel, respectively. When the operation buttons 46 and 47 receive a user operation, they output a signal indicating the reception of the operation to the control unit 60. The functions assigned to the operation buttons 46 and 47 are not limited to confirm and cancel, but may be "start heating" or the like. In addition to the operation buttons 46 and 47, the cooking device 100 may further be provided with a plurality of buttons to which specific functions are assigned.

[0018] The control unit 60 controls the heating unit 50 and the touch panel display 41. Specifically, it includes a processor such as a CPU (Central Processing Unit). The storage unit 70 stores various programs and data. Specifically, the storage unit 70 includes a semiconductor memory such as a ROM (Read Only Memory) and a RAM (Random Access Memory), a solid state drive (SSD), or a hard disk drive (HDD). The control unit 60 reads out and executes various programs from the storage unit 70 to control the display of the touch panel display 41 and obtain the display contents of the screen displayed on the touch panel display 41.

[0019] The various sensors 80 are, for example, a temperature sensor, a humidity sensor, and an opening / closing sensor for the opening / closing door 30. The temperature sensor is disposed in the cooking chamber 20. The temperature sensor measures the temperature in the cooking chamber 20 and outputs a signal indicating the measurement result to the control unit 60. The humidity sensor is disposed in the cooking chamber 20. The humidity sensor measures the humidity in the cooking chamber 20 and outputs a signal indicating the measurement result to the control unit 60. The opening / closing sensor is disposed in the opening / closing door 30 or the housing 10. The opening / closing sensor determines whether the opening / closing door 30 is open or closed, and outputs a signal indicating the determination result to the control unit 60. Note that the various sensors 80 are not limited to the above examples. In this way, the various sensors 80 detect the state of the cooking chamber 20 or the heating unit 50.

[0020] The control unit 60 controls the heating unit 50 and the touch panel display 41 based on signals from the touch panel display 41 , the operation buttons 46 and 47 , and various sensors 80 .

[0021] Next, with reference to Fig. 3 to Fig. 5, the display process of the touch panel display 41 during the cooking process of the cooking object by the cooking appliance 100 will be described. Fig. 3 is a diagram showing an example of a screen displayed on the touch panel display 41 during the cooking process of the cooking object. Fig. 4 is a diagram showing another example of a screen displayed on the touch panel display 41 during the cooking process of the cooking object. Fig. 4 shows a continuation of the cooking process of Fig. 3. Fig. 5 is a diagram showing another example of a screen displayed on the touch panel display 41 during the cooking process of the cooking object. Fig. 5 shows a cooking process that is a continuation of the cooking process of Fig. 3 and is different from that of Fig. 4.

[0022] 3 to 5, the horizontal axis indicates the time axis, and the screens displayed on the touch panel display 41 are shown along the passage of time.

[0023] In this embodiment, a state in which the opening / closing door 30 of the cooking device 100 is not opened or closed and the touch panel display 41 and the operation buttons 46, 47 are not operated for a predetermined period of time is called a "standby state." In the standby state, the backlight of the touch panel display 41 is turned off and the screen is not displayed. Hereinafter, the state in which the backlight of the touch panel display 41 in the standby state is turned off is called "screen off." The display surface of the touch panel display 41 in the "screen off" state is also called "screen sleep."

[0024] 3, the cooking device 100 is in a standby state until time T1. That is, the touch panel display 41 is in a "screen sleep" state. For example, at time T1, when the user operates the touch panel display 41 or the operation buttons 46, 47, or opens and closes the opening and closing door 30, the cooking device 100 releases the "standby state."

[0025] Specifically, when control unit 60 receives a signal indicating the detection result of a tap from touch panel display 41, a signal indicating acceptance of an operation from operation buttons 46, 47, or a signal indicating a determination result from the open / close sensor in the "standby state", it turns on the backlight of touch panel display 41. Hereinafter, the state in which the backlight of touch panel display 41 is turned on is referred to as "screen on". In this embodiment, "screen on" refers to the start of a cooking period.

[0026] Furthermore, the control unit 60 turns on the backlight by the control unit 60 and controls the touch panel display 41 to display screen V1. Screen V1 is a screen that is displayed on the touch panel display 41 when the "standby state" of the cooking device 100 is released. For example, in this embodiment, image data showing screen V1 is stored in the storage unit 70. As an example, screen V1 is a main menu screen. The control unit 60 controls the touch panel display 41 to display screen V1 based on the image data in the storage unit 70.

[0027] When screen V1 is displayed on touch panel display 41, control unit 60 acquires the display content of screen V1 displayed on touch panel display 41, generates display history data D1 indicating the display content of screen V1, and stores it in storage unit 70. In other words, when the display surface of touch panel display 41 switches from "screen sleep" to screen V1, display history data D1 is stored in storage unit 70.

[0028] In this way, by storing the display contents of screen V1 displayed on touch panel display 41 in storage unit 70 as display history data D1, screen V1 can be referenced at times other than when screen V1 was displayed on touch panel display 41. Therefore, by referring to the display history data D1 stored in storage unit 70, the operating state of the internal configuration of the cooking appliance when screen V1 was displayed on touch panel display 41 can be inferred. Therefore, for example, signs of an error occurring can be easily discovered.

[0029] Specifically, the control unit 60 captures the screen V1 displayed on the touch panel display 41 and generates still image data P1 showing the screen V1. The control unit 60 also generates display history data D1 by associating the generation time of the still image data P1 with the still image data P1. Note that instead of the still image data P1, the control unit 60 may generate video data by screen recording the screen displayed on the touch panel display 41 during a predetermined period. Hereinafter, the process of acquiring the screen of the touch panel display 41 by the control unit 60 is similar to the process of acquiring the screen V1, and therefore a description thereof will be omitted.

[0030] This allows the screen V1 displayed on the touch panel display 41 to correspond to the time at which the screen V1 was displayed, making it easier for the user to understand the display history of the touch panel display 41.

[0031] Furthermore, when the user operates the touch panel display 41 or the operation buttons 46, 47 in accordance with the screen V1, the control unit 60 controls the touch panel display 41 so as to switch the screen to be displayed in response to the operation.

[0032] For example, the control unit 60 controls the touch panel display 41 to display the screen V2 in response to a user operation. As an example, the screen V2 is a first condition input screen for inputting the amount of ingredients for the cooking method selected by the user. Note that one or more screens may be displayed on the touch panel display 41 in a switching manner between when the screen V1 is displayed and when the screen V2 is displayed.

[0033] At time T2, when screen V2 is displayed on touch panel display 41, control unit 60 acquires the display content of screen V2 displayed on touch panel display 41, generates display history data D2 indicating the display content of screen V2, and stores it in storage unit 70. In this way, control unit 60 acquires the display content of the screen every time the screen displayed on touch panel display 41 is switched.

[0034] In this way, by storing the display history of touch panel display 41 over time, it becomes easier to predict changes in the operating state of the internal configuration of cooking appliance 100 over time.

[0035] [Cooking process 1] Next, a case where the cooking process in FIG. 4 has been reached will be described. When the user operates the touch panel display 41 or the operation buttons 46, 47 according to the screen V2, the control unit 60 controls the touch panel display 41 to switch the screen to be displayed according to the operation. For example, the control unit 60 controls the touch panel display 41 to switch the screen from the screen V2 and display the screen V3 according to the user's operation. As an example, the screen V3 is a second condition input screen for inputting the finish conditions of the cooking method selected by the user. When the screen V3 is displayed on the touch panel display 41 at time T3, the control unit 60 acquires the display contents of the screen V3 displayed on the touch panel display 41, generates display history data D3 indicating the display contents of the screen V3, and stores the data in the storage unit 70.

[0036] When the user operates the touch panel display 41 or the operation buttons 46, 47 in accordance with the screen V3, the control unit 60 controls the touch panel display 41 to switch the screen to be displayed in response to the operation. Also, for example, when an operation is performed on the screen V3 or when the operation button 46 is operated while the screen V3 is being displayed on the touch panel display 41, the control unit 60 controls the heating unit 50 to start heating.

[0037] When heating by the heating unit 50 starts, the control unit 60 controls the touch panel display 41 to display a screen V4. As an example, the screen V4 is a countdown screen. The countdown screen includes a countdown display indicating the remaining time until heating by the heating unit 50 is completed. When the screen V4 is displayed on the touch panel display 41 at time T4, the control unit 60 acquires the display content of the screen V4 displayed on the touch panel display 41, generates display history data D4 indicating the display content of the screen V4, and stores the data in the storage unit 70.

[0038] When the countdown screen is displayed on the touch panel display 41, the displayed screen does not change until the countdown display reaches "0 seconds". Specifically, the control unit 60 controls the touch panel display 41 to display a countdown screen in which the number of seconds in the countdown display is decreased by one second every second. In other words, after time T4, the countdown display on the countdown screen only changes, and the screen displayed on the touch panel display 41 does not change from the countdown screen. Therefore, the control unit 60 does not acquire the display contents of the screen displayed on the touch panel display 41 in response to the change in the countdown display. In other words, the control unit 60 acquires the display contents of the screen V4 only at the timing when the touch panel display 41 switches to the screen V4.

[0039] In this way, by reducing the frequency of acquiring the display contents during the period when the countdown display is displayed on the touch panel display 41, the total amount of display history data generated during the cooking period can be reduced, and as a result, the amount of storage capacity used by the storage unit can be reduced.

[0040] When the countdown display reaches "0 seconds," the control unit 60 controls the touch panel display 41 to display screen V5. As an example, screen V5 is a completion screen indicating completion of cooking. The control unit 60 acquires the display content of screen V5 displayed on the touch panel display 41, generates display history data D5 indicating the display content of screen V5, and stores it in the storage unit 70. The control unit 60 also controls the heating unit 50 to stop heating.

[0041] At time T6, a predetermined period of time having elapsed since time T5 when screen V5 was displayed on touch panel display 41, control unit 60 turns off the backlight of touch panel display 41 and puts the display surface of touch panel display 41 into "screen sleep" mode. In this embodiment, "screen off" means the end of the cooking period.

[0042] For example, when cooking of the cooking target is completed in the cooking appliance 100, the control unit 60 deletes the display history data D1 to D5 from the storage unit 70. Specifically, the control unit 60 deletes the display history data D1 to D5 from the storage unit 70 after time T6.

[0043] In this way, when cooking of the food to be cooked is completed without occurrence of an error or the like, the display history data generated during the cooking period is highly likely to indicate that there is no abnormality in the cooking appliance 100. In general, compared with the display history data when there is no abnormality in the cooking appliance 100, the display history data when there is an abnormality in the cooking appliance 100 is more useful for estimating the operating state of the internal configuration of the cooking appliance 100. Therefore, the display history data when cooking of the food to be cooked is completed without occurrence of an error or the like is deleted from the storage unit 70 after cooking is completed. Therefore, it becomes easier to ensure sufficient free space in the storage unit.

[0044] [Cooking process 2] Next, following on from Fig. 3, a case where the cooking process in Fig. 5 has been reached will be described. The cooking process in Fig. 5 is the same as that in Fig. 4 until screen V4 is displayed on touch panel display 41. Therefore, the process after time T4 when screen V4 is displayed on touch panel display 41 will be described.

[0045] In this embodiment, the various sensors 80 detect the occurrence of an error in the cooking device 100. The various sensors 80 are an example of a detection unit. In other words, the control unit 60 and the various sensors 80 monitor the state of the cooking chamber 20 and the heating unit 50. That is, the control unit 60 judges an error in the cooking chamber 20 or an error in the heating unit 50 according to the detection result of the sensor 80. Specifically, the control unit 60 judges whether or not there is an abnormality in the cooking device 100 including the cooking chamber 20 or the heating unit 50 based on a signal indicating the measurement result from the sensor 80. When the control unit 60 judges that there is no abnormality in the cooking device 100, the cooking process proceeds to the cooking process of FIG. 4.

[0046] On the other hand, if the control unit 60 determines that there is an abnormality in the cooking device 100, the cooking process proceeds to the cooking process in Fig. 5. For example, assume that the control unit 60 and the various sensors 80 detect the occurrence of an error in the cooking device 100 at time T7 when screen V7, which is a countdown screen including a "6 seconds" countdown display, is displayed on the touch panel display 41.

[0047] At this time, the control unit 60 acquires the display contents of the screen V7 displayed on the touch panel display 41 at the timing of the error detection, generates display history data D7 indicating the display contents of the screen V7, and stores the data in the storage unit 70. Meanwhile, the control unit 60 controls the touch panel display 41 to switch the displayed screen to the screen V8 according to the error determination result by the control unit 60. The screen V8 is an error screen indicating an error. The error screen includes an image indicating an error code according to the type of error.

[0048] By acquiring the display contents of screen V7 displayed on touch panel display 41 at the time the error was detected, that is, the screen displayed on touch panel display 41 immediately before the error screen, in addition to the error screen, the user can easily recognize the time when the error occurred.

[0049] When screen V8 is displayed on touch panel display 41, control unit 60 acquires the display content of screen V8 displayed on touch panel display 41, generates display history data D8 indicating the display content of screen V8, and stores the data in storage unit 70. In this way, display history data D8 includes the display content of the error screen.

[0050] When the control unit 60 determines that there is an error in the cooking chamber 20 or the heating unit 50, it acquires the measurement result contained in the signal from the sensor 80. The control unit 60 stores the measurement result of the sensor 80 acquired by the control unit 60 in the storage unit 70 in association with the display history data D8.

[0051] In this way, by storing the measurement result of the sensor 80 in the storage unit 70 together with the display history of the touch panel display 41, the measurement result of the sensor 80 at the timing when the error occurred can be referred to, for example, after a cooking period. Therefore, it becomes easier to guess the details of the operating state of the internal configuration of the cooking device 100 at the timing when the error occurred.

[0052] The measurement results of the sensor 80 acquired by the control unit 60 may be associated with the display history data D7 instead of the display history data D8.

[0053] For example, when a predetermined operation is input to touch panel display 41, operation button 46, or operation button 47, control unit 60 refers to storage unit 70 and causes touch panel display 41 to display a history screen corresponding to any of the display history data stored in storage unit 70. Typically, control unit 60 causes touch panel display 41 to display a history screen corresponding to display history data D8 at the time an error occurred.

[0054] In this way, the display history data D8 can be viewed on the touch panel display 41 at a timing other than the cooking period. That is, the user can view the error screen indicated by the display history data D8 at a timing different from the timing when the error occurred. Therefore, it becomes easier to deal with the error at a timing other than the cooking period.

[0055] At this time, the control unit 60 may cause the touch panel display 41 to display a display indicating the measurement results associated with the display history data D8 together with the display history data D8.

[0056] In this embodiment, when touch panel display 41 turns on the "screen light," acquisition of the display contents of the screen being displayed on touch panel display 41 begins. Alternatively, for example, the control unit 60 may be configured to start acquiring the display contents of the screen after heating by heating unit 50 begins.

[0057] Specifically, the control unit 60 does not acquire the display contents of the screen displayed on the touch panel display 41 before screen V3 shown in FIG. 4 or FIG. 5, which is the screen displayed when heating by the heating unit 50 begins, but acquires the display contents of the screen that switches after screen V3.

[0058] Generally, errors in the cooking device 100 are likely to occur during the period when the device is being heated by the heating unit 50. Therefore, by limiting the acquisition period of the display contents of the screen displayed on the touch panel display 41 to the period when the device is being heated by the heating unit 50, the frequency of acquiring the display contents is reduced, and the total amount of display history data generated during the cooking period can be reduced. As a result, the amount of storage capacity used by the storage unit can be reduced.

[0059] In order to reduce the amount of storage capacity used by the storage unit, when the total amount of display history data stored in the storage unit 70 exceeds a predetermined value, some or all of the display history data may be deleted.

[0060] Next, a method for storing a display history in the cooking device 100 according to the present embodiment will be described with reference to Fig. 6. Fig. 6 is a flowchart showing a method for storing a display history in the cooking device 100 according to the present embodiment.

[0061] First, when an operation is performed on the heating cooker 100, the touch panel display 41 of the heating cooker 100 turns on the screen and a screen is displayed on the touch panel display 41 (step S11), the control unit 60 acquires the display content of the screen displayed on the touch panel display 41, generates display history data indicating the display content of the screen, and stores it in the memory unit 70 (step S12).

[0062] The control unit 60 switches the screen displayed on the touch panel display 41 in response to a user's operation on the cooking appliance 100 (step S13). When the control unit 60 switches the screen displayed on the touch panel display 41, the control unit 60 acquires the display content of the screen displayed on the touch panel display 41, generates display history data indicating the display content of the screen, and stores the data in the storage unit 70 (step S14).

[0063] Furthermore, when the control unit 60 and the various sensors 80 detect the occurrence of an error in the cooking device 100 (Yes in step S15), the control unit 60 acquires the display contents of the screen displayed on the touch panel display 41 at the time the error was detected, generates display history data indicating the display contents, and stores the data in the memory unit 70 (step S16).

[0064] Next, the control unit 60 switches the screen displayed on the touch panel display 41 to an error screen (step S17). The control unit 60 acquires the display contents of the error screen, generates display history data indicating the display contents, and stores the data in the storage unit 70 (step S18). The touch panel display 41 turns off the screen, and the cooking appliance 100 transitions to a standby state (step S19). The cooking appliance 100 maintains the standby state until an operation is performed on the cooking appliance 100 (step S11).

[0065] On the other hand, if the control unit 60 and the various sensors 80 do not detect the occurrence of an error in the heating cooker 100 (No in step S15), the control unit 60 switches the screen displayed on the touch panel display 41 in accordance with the user's operation on the heating cooker 100 (step S13) until cooking is completed (No in step S20).

[0066] When cooking is completed (Yes in step S20), the control unit 60 deletes the display history data from the storage unit 70 (step S21). The touch panel display 41 turns off the screen, and the cooking device 100 transitions to a standby state (step S19). The cooking device 100 maintains the standby state until an operation is performed on the cooking device 100 (step S11).
