[0010] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the present disclosure, there was a technology for setting the heating time of a heating device by operating a key, which is a button. However, in the conventional technology, the key combination is fixed, so depending on the desired heating time, the user needs to operate many keys. Therefore, in the conventional technology, it may be time-consuming to set the heating time, and the inventors discovered a problem that there is room for improvement in improving the user's convenience regarding setting the heating time, and have come to constitute the subject of the present disclosure in order to solve the problem. Therefore, the present disclosure provides a heating device, a control method for a heating device, and a program that can improve user convenience in setting a heating time.

[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanations than necessary may be omitted. For example, detailed explanations of already well-known matters or duplicate explanations of substantially the same configurations may be omitted. It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] (Embodiment 1) [1-1. Configuration] [1-1-1. Configuration of heating device] FIG. 1 is a perspective view of a heating device 1 according to the first embodiment. The heating device 1 shown in Fig. 1 has a box-shaped cabinet 2. In Fig. 1 and Fig. 2 described later, arrows indicate directions corresponding to the cabinet 2 in an installed state of the heating device 1. The symbol UP indicates the upward direction, the symbol DW indicates the downward direction, the symbol FR indicates the forward direction, the symbol RE indicates the rearward direction, the symbol R indicates the rightward direction, and the symbol L indicates the leftward direction.

[0013] A door 3 is provided on the front of the cabinet 2 so as to be able to open and close. In the heating device 1, when the door 3 is opened, a heating chamber 4 provided inside the cabinet 2 is exposed. The heating chamber 4 accommodates an object to be heated by the heating device 1. The heating device 1 is a cooking appliance that heats the object accommodated in the heating chamber 4, thereby cooking the object. Note that the object to be heated in this embodiment is food.

[0014] The heating device 1 has a plurality of heating modes and heats the object to be heated in a heating mode designated by a user. In this embodiment, the heating device 1 has at least five heating modes: a microwave mode, an oven mode, a steam mode, a grill mode, and a fermentation mode.

[0015] The microwave oven mode is a mode in which microwaves are used to heat an object to be heated. The oven mode is a mode in which a heater is used to heat an object to be heated. The steam mode is a mode in which steam is used to heat an object to be heated. The grill mode is a mode in which an object to be heated placed on the grill pan is heated by microwaves, or a heater, or by microwaves and a heater. The grill pan is a container coated with a material that generates heat when irradiated with microwaves. The grill mode is subdivided into a double-sided grill mode, an upper grill mode, and a lower grill mode. The double-sided grill mode is a mode in which both the upper surface (the surface facing the upper surface of the heating chamber 4) and the lower surface (the surface facing the placement surface of the grill pan) of an object to be heated placed on the grill pan are heated. The upper grill mode is a mode in which the upper surface of an object to be heated placed on the grill pan is heated. The lower grill mode is a mode in which the lower surface of an object to be heated placed on the grill pan is heated. The fermentation mode is a mode in which the heater is used to heat the object to be heated at a lower temperature than in the oven mode.

[0016] Returning to the description of the configuration of the heating device 1, an operation panel 5 is arranged on the front side of the cabinet 2 so as to be aligned with the door 3. The operation panel 5 may be arranged on the front side of the door 3. As will be described with reference to FIG. 2, the operation panel 5 includes switches and the like that accept operations by a user.

[0017] [1-1-2. Operation panel configuration] FIG. 2 is a front view of operation panel 5 in the first embodiment. The operation panel 5 includes a back switch 51, a cancel switch 52, a start switch 53, and a touch panel 54. The touch panel 54 is an example of a "display unit."

[0018] The back switch 51 is a switch for returning the screen displayed on the touch panel 54 to the previous screen. Note that the previous screen is the screen that was displayed before transitioning to the currently displayed screen. When the heating device 1 is not performing heating, the cancel switch 52 functions as a switch for canceling an operation performed on the touch panel 54. When the heating device 1 is performing heating, the cancel switch 52 functions as a switch for stopping the heating being performed. The start switch 53 is a switch for starting heating.

[0019] The touch panel 54 is composed of a display panel and a touch sensor that is provided on top of or integral with the display panel. The touch panel 54 of the present embodiment displays a setting screen SG for setting heating conditions. The screen displayed by the touch panel 54 is not limited to the setting screen SG, and may include other screens such as a screen for setting wireless communication, a screen for setting alarm sounds, and a screen for setting interior lights.

[0020] Details of the setting screen SG will be described later, but here, a brief explanation will be given of the heating conditions set on the setting screen SG. The heating conditions set on the setting screen SG include a heating mode, a heating temperature, a heating output, or a heating degree corresponding to the heating mode, and a heating time. For example, in setting the microwave oven mode, the heating conditions set on the setting screen SG include the microwave oven mode, a heating output (output value of the magnetron), and a heating time.

[0021] [1-1-3. Configuration of the heating device control system] FIG. 3 is a block diagram showing the configuration of a control system of the heating device 1. The heating device 1 includes a control device 10, an operation panel 5, a heating unit 11, and a sound output unit 12. The control device 10 is a device that controls each part of the heating device 1. The operation panel 5, the heating unit 11, and the sound output unit 12 are connected to the control device 10.

[0022] As described above, the operation panel 5 includes the back switch 51, the cancel switch 52, the start switch 53, and the touch panel . The return switch 51 outputs an operation signal to the control device 10 when the return switch 51 is operated. The cancel switch 52 outputs an operation signal to the control device 10 when the cancel switch 52 is operated. The start switch 53 outputs an operation signal to the control device 10 when the start switch 53 is operated. The touch panel 54 outputs an operation signal to the control device 10 when the touch panel 54 is touched.

[0023] Heating unit 11 heats heating chamber 4 under the control of control device 10. Heating unit 11 includes mechanisms related to heating, such as a magnetron, a radiant heater unit that heats an object to be heated by radiant heat, a convection heater unit that circulates hot air inside heating chamber 4, a steam generation unit that generates steam inside heating chamber 4, and a cooling fan. The steam generation unit includes a tank to which water is supplied, a steam heater that heats the water in the tank to generate steam, and the like.

[0024] The sound output unit 12 is a device that outputs an alarm sound, and may be a buzzer or another type of speaker.

[0025] The control device 10 includes a processor 100 such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), a memory 110, and an interface circuit to which other devices are connected.

[0026] The memory 110 is a memory that stores programs and data. The memory 110 stores a control program 111 and data to be processed by the processor 100. The memory 110 has a non-volatile storage area. The memory 110 also has a volatile storage area and constitutes a work area of ​​the processor 100. The memory 110 is constituted by, for example, a Read Only Memory (ROM) or a Random Access Memory (RAM). The control program 111 is an example of a "program."

[0027] The processor 100 reads out and executes a control program 111 stored in the memory 110, thereby functioning as a reception unit 101, a display control unit 102, a notification unit 103, and a heating control unit 104.

[0028] The reception unit 101 receives operations performed by the user on the operation panel 5, based on operation signals output by the operation panel 5. The operations performed on the operation panel 5 include operations on various switches included in the operation panel 5 and operations on the touch panel 54.

[0029] The display control unit 102 controls the display of the touch panel 54 in accordance with the content of the operation accepted by the acceptance unit 101 .

[0030] The notification unit 103 notifies predetermined content by the sound output unit 12 .

[0031] The heating control unit 104 controls the heating unit 11 based on the content of the operation accepted by the acceptance unit 101 via the touch panel 54. In other words, the heating control unit 104 controls the heating unit 11 based on the heating conditions set on the setting screen SG.

[0032] When the heating mode set on the setting screen SG is the microwave mode, the heating control unit 104 heats the object to be heated by the magnetron based on the heating output and heating time set on the setting screen SG.

[0033] When the heating mode set on the setting screen SG is the oven range mode, the heating control unit 104 heats the object to be heated using the radiant heater unit and the convection heater based on the heating temperature and heating time set on the setting screen SG.

[0034] When the heating mode set on the setting screen SG is the steam mode, the heating control unit 104 heats the object to be heated using the radiant heater unit, the convection heater, and the steam generation unit based on the heating temperature and heating time set on the setting screen SG.

[0035] When the heating mode set on the setting screen SG is the double-sided grill mode, the heating control unit 104 heats the object to be heated using the magnetron, the radiant heater unit, and the convection heater based on the heating time set on the setting screen SG.

[0036] When the heating mode set on the setting screen SG is the upper grill mode, the heating control unit 104 heats the object to be heated by the radiant heater unit and the convection heater based on the heating time set on the setting screen SG.

[0037] When the heating mode set on the setting screen SG is the lower grill mode, the heating control unit 104 heats the object to be heated by the magnetron based on the heating time set on the setting screen SG.

[0038] When the heating mode set on the setting screen SG is the fermentation mode, the heating control unit 104 heats the object to be heated using the radiant heater unit and the convection heater based on the heating temperature and heating time set on the setting screen SG.

[0039] [1-1-4. Configuration of the setting screen] Next, the configuration of the setting screen SG will be described. Fig. 4 is a diagram for explaining the setting screen SG. Fig. 4 shows an example of the setting screen SG relating to the setting of the microwave oven mode.

[0040] The setting screen SG at the top left of Fig. 4 is a screen for setting the heating mode. The setting screen SG at the top left of Fig. 4 has a range key RKy for setting the heating mode to the microwave mode. In addition to the range key RKy, the setting screen SG at the top left of Fig. 4 also has a key for setting the heating mode to a mode other than the microwave mode.

[0041] When the range key RKy is operated on the setting screen SG on the top left of FIG. 4, the display control unit 102 causes the touch panel 54 to display the setting screen SG on the top right of FIG.

[0042] 4 has a first output setting key WKy1 for setting the heating output, i.e., the output value of the magnetron, to 600 W (watts), a second output setting key WKy2 for setting the heating output to 500 W, and a third output setting key WKy3 for setting the heating output to an output other than 600 W and 500 W. Examples of outputs other than 600 W and 500 W include 800 W, 300 W, and 150 W.

[0043] The setting screen SG on the upper right of Fig. 4 has a heating time display area TA1. The heating time display area TA1 displays the heating time set by the time setting key SKy. At the start of display, the heating time display area TA1 displays a heating time of "0 seconds."

[0044] The setting screen SG on the top right of Fig. 4 displays three time setting keys SKy. That is, the setting screen SG on the top right of Fig. 4 displays a "5 minute" time setting key SKy1, a "1 minute" time setting key SKy2, and a "10 second" time setting key SKy3. The "5 minute" time setting key SKy1 is a key that adds a heating time of "5 minutes" to the heating time displayed in the heating time display area TA1 with one operation. The "1 minute" time setting key SKy2 is a key that adds a heating time of "1 minute" to the heating time displayed in the heating time display area TA1 with one operation. The "10 second" time setting key SKy3 is a key that adds a heating time of "10 seconds" to the heating time displayed in the heating time display area TA1 with one operation.

[0045] 4 illustrates an example in which the heating output is set to 600 W from the time when the time setting key SKy starts to be displayed. Therefore, as will be made clear later, the setting screen SG shown in FIG 4 displays a combination of the "5 minutes" time setting key SKy1, the "1 minute" time setting key SKy2, and the "10 seconds" time setting key SKy3.

[0046] When the time setting key SKy is operated to set the heating temperature displayed in the heating time display area TA1 to "29 minutes" on the setting screen SG at the top right of Fig. 4, the display control unit 102 causes the touch panel 54 to display the setting screen SG at the bottom right of Fig. 4. When the time setting key SKy1 or time setting key SKy2 is operated on the setting screen SG at the bottom right of Fig. 4, the display control unit 102 causes the touch panel 54 to display the setting screen SG at the bottom left of Fig. 4.

[0047] The setting screen SG on the lower left of FIG. 4 indicates that the set heating time is "30 minutes." In this embodiment, for heating at 600 W in microwave mode, an upper limit of "30 minutes" is set for the settable heating time. Therefore, even if the time setting key SKy1 is operated on the setting screen SG on the lower right of FIG. 4, a heating time exceeding 30 minutes cannot be set on the setting screen SG. Therefore, even if the time setting key SKy1 is operated on the setting screen SG on the lower right of FIG. 4, a heating time exceeding 30 minutes cannot be set on the setting screen SG, as shown on the setting screen SG on the lower left of FIG. 4. In the following description, the upper limit of the heating time that can be set is appropriately referred to as the "maximum heating time."

[0048] In the setting screen SG on the lower left of Fig. 4, the heating time is set to the maximum heating time. Therefore, even if the time setting key SKy is operated in the setting screen SG on the lower left of Fig. 4, the heating time displayed in the heating time display area TA1 in the setting screen SG does not change. Note that, when the time setting key SKy is operated in the setting screen SG on the lower left of Fig. 4, the heating device 1 notifies by sound that the time setting key SKy has been operated beyond the upper limit.

[0049] Fig. 5 is a diagram for explaining the setting screen SG, showing an example of the setting screen SG relating to the setting of the oven mode.

[0050] The setting screen SG at the top left of FIG. 5 is a screen for setting the heating mode. The setting screen SG at the top left of FIG. 5 has an oven key OKy, which is a key for setting the heating mode to the oven mode. The setting screen SG at the top left of FIG. 5 has a first oven key OKy1, a second oven key OKy2, a third oven key OKy3, and a fourth oven key OKy4. The first oven key OKy1 is a key operated when heating with preheating is performed when the shelf for placing the object to be heated is in one stage. The second oven key OKy2 is a key operated when heating with preheating is performed when the shelf for placing the object to be heated is in two stages. The third oven key OKy3 is a key operated when heating without preheating is performed when the shelf for placing the object to be heated is in one stage. The fourth oven key OKy4 is a key operated when heating without preheating is performed when the shelf for placing the object to be heated is in two stages.

[0051] When the third oven key OKy3 is operated on the setting screen SG on the top left of FIG. 5, the display control unit 102 causes the touch panel 54 to display the setting screen SG on the top right of FIG.

[0052] The setting screen SG on the top right of FIG. 5 has a heating temperature display area TA2, a first temperature setting key TKy1, and a second temperature setting key TKy2. The heating temperature display area TA2 is an area that displays the heating temperature. When the heating temperature display area TA2 starts to be displayed, the heating temperature display area TA2 displays a default heating temperature, such as 170°C. The first temperature setting key TKy1 is a key that adds a predetermined temperature to the heating temperature displayed in the heating temperature display area TA2 with one operation. An example of this predetermined temperature is 10°C. The second temperature setting key TKy2 is a key that subtracts a predetermined temperature from the heating temperature displayed in the heating temperature display area TA2 with one operation.

[0053] The setting screen SG at the top right of FIG. 5 has a heating time display area TA1. The setting screen SG at the top right of FIG. 5 displays four time setting keys SKy. That is, the setting screen SG at the top right of FIG. 5 displays a "10 minutes" time setting key SKy4, a "1 minute" time setting key SKy2, a "30 seconds" time setting key SKy5, and a "1 hour" time setting key SKy6. The "10 minutes" time setting key SKy4 is a key for adding "10 minutes" to the heating time indicated in the heating time display area TA1 with one operation. The "30 seconds" time setting key SKy5 is a key for adding "30 seconds" to the heating time indicated in the heating time display area TA1 with one operation. The "1 hour" time setting key SKy6 is a key for adding "1 hour" to the heating time indicated in the heating time display area TA1 with one operation.

[0054] 5 illustrates an example in which the heating temperature is set to 170° C. from the time when the time setting key SKy starts to be displayed. Therefore, as will be made clear later, the setting screen SG illustrated in FIG 5 displays a combination of the "10 minutes" time setting key SKy4, the "1 minute" time setting key SKy2, the "30 seconds" time setting key SKy5, and the "1 hour" time setting key SKy6.

[0055] When the time setting key SKy is operated to change the heating time displayed in the heating time display area TA1 to "1 hour 59 minutes" on the setting screen SG at the top right of Fig. 5, the display control unit 102 causes the touch panel 54 to display the setting screen SG at the bottom right of Fig. 5. When any of the time setting keys SKy4, SKy2, SKY6 is operated on the setting screen SG at the bottom right of Fig. 5, the display control unit 102 causes the touch panel 54 to display the setting screen SG at the bottom left of Fig. 5.

[0056] The setting screen SG on the lower left of FIG. 5 indicates that the set heating time is "2 hours". In this embodiment, in heating at 170° C. in oven mode, an upper limit of "2 hours" is set for the settable heating time. Therefore, even if the time setting keys SKy4 and SKy6 are operated on the setting screen SG on the lower right of FIG. 5, a heating time exceeding "2 hours" cannot be set on the setting screen SG. Therefore, even if the time setting keys SKy4 and SKy6 are operated on the setting screen SG on the lower right of FIG. 5, a heating temperature exceeding "2 hours" cannot be set on the setting screen SG, as shown on the setting screen SG on the lower left of FIG.

[0057] In the setting screen SG on the lower left of Fig. 5, the heating time is set to the maximum heating time. Therefore, even if the time setting key SKy is operated in the setting screen SG on the lower left of Fig. 5, the heating time displayed in the heating time display area TA1 in the setting screen SG does not change. Note that, when the time setting key SKy is operated in the setting screen SG on the lower left of Fig. 5, the heating device 1 notifies by sound that the time setting key SKy has been operated beyond the upper limit.

[0058] Fig. 6 is a diagram for explaining the setting screen SG, showing an example of the setting screen SG relating to the setting of the oven mode.

[0059] The setting screen SG at the top left of FIG. 6 is a screen for setting the heating mode. The setting screen SG at the top left of FIG. 6 has a grill key GKy for setting the heating mode to the grill mode. That is, the setting screen SG at the top left of FIG. 6 has a first grill key GKy1, a second grill key GKy2, a third grill key GKy3, and a fourth grill key GKy4. The first grill key GKy1 is a grill key GKy for setting the double-sided grill mode, and is a key operated when heating is performed with the grill pan installed at the top. The second grill key GKy2 is a grill key GKy for setting the double-sided grill mode, and is a key operated when heating is performed with the grill pan installed at the middle. The third grill key GKy3 is a key for setting the upper grill mode. The fourth grill key GKy4 is a key for setting the lower grill mode.

[0060] When the first grill key GKy1 is operated on the setting screen SG on the top left of FIG. 6, the display control unit 102 causes the touch panel 54 to display the setting screen SG on the top right of FIG.

[0061] The setting screen SG on the upper right of FIG. 6 has a first heating degree setting key DKy1, a second heating degree setting key DKy2, and a third heating degree setting key DKy3. The first heating degree setting key DKy1 is a key for setting the heating degree of the object to be heated to "low". The second heating degree setting key DKy2 is a key for setting the heating degree of the object to be heated to "standard". The "standard" heating degree of the object to be heated means that the heating degree is higher than "low". The third heating degree setting key DKy3 is a key for setting the heating degree of the object to be heated to "high". The "high" heating degree of the object to be heated means that the heating degree is higher than "standard".

[0062] The setting screen SG on the top right of Fig. 6 has a heating time display area TA1. The setting screen SG on the top right of Fig. 6 also displays three time setting keys SKy. That is, the setting screen SG on the top right of Fig. 6 displays a "10 minute" time setting key SKy4, a "1 minute" time setting key SKy2, and a "30 seconds" time setting key SKy5.

[0063] 6 illustrates an example in which the heating level is set to "standard" from the time when the time setting key SKy starts to be displayed. Therefore, as will be described later, the setting screen SG shown in FIG 6 displays a combination of the "10 minutes" time setting key SKy4, the "1 minute" time setting key SKy2, and the "30 seconds" time setting key SKy5.

[0064] When the time setting key SKy is operated to set the heating time displayed in the heating time display area TA1 to "29 minutes" on the setting screen SG at the top right of Fig. 6, the display control unit 102 causes the touch panel 54 to display the setting screen SG at the bottom right of Fig. 6. When either the time setting key SKy4 or SKy2 is operated on the setting screen SG at the bottom right of Fig. 6, the touch panel 54 displays the setting screen SG at the bottom left of Fig. 6.

[0065] The setting screen SG on the lower left of FIG. 6 shows a set heating time of "30 minutes". In the double-sided grill mode of this embodiment, an upper limit of "30 minutes" is set for the settable heating time. Therefore, even if the time setting key SKy4 is operated on the setting screen SG on the lower right of FIG. 6, a heating temperature exceeding "30 minutes" cannot be set on the setting screen SG. Therefore, even if the time setting key SKy4 is operated on the setting screen SG on the lower right of FIG. 6, a heating temperature exceeding "30 minutes" cannot be set on the setting screen SG, as shown on the setting screen SG on the lower left of FIG. 6.

[0066] In the setting screen SG on the lower left of Fig. 6, the heating time is set to the maximum heating time. Therefore, even if the time setting key SKy is operated in the setting screen SG on the lower left of Fig. 6, the heating time displayed in the heating time display area TA1 in the setting screen SG does not change. Note that, when the time setting key SKy is operated in the setting screen SG on the lower left of Fig. 6, the heating device 1 notifies by sound that the time setting key SKy has been operated beyond the upper limit.

[0067] As described above with reference to Figures 4 to 6, the combination of the time setting keys SKy displayed on the setting screen SG is a combination according to the heating mode set on the setting screen SG. In the present embodiment, the combination of the time setting keys SKy displayed on the setting screen SG is a combination according to the setting of the heating mode as well as any one of the heating temperature, heating output, and heating degree. 4 to 6, the upper limit of the heating time that can be set on the setting screen SG is an upper limit that corresponds to the heating mode. In the present embodiment, the upper limit of the heating time that can be set on the setting screen SG is an upper limit that corresponds to the setting of the heating mode as well as any one of the heating temperature, heating output, and heating degree.

[0068] The combination of the time setting key SKy and the upper limit of the heating time will be described in detail with reference to FIG. FIG. 7 is a table showing combinations of the time setting keys SKy and the upper limit of the heating time.

[0069] 7, when the heating mode is set to the microwave mode and the heating output is set to 800 W, the setting screen SG displays a time setting key SKy2 for "1 minute" and a time setting key SKy3 for "10 seconds." In this case, the upper limit of the heating time that can be set on the setting screen SG is "6 minutes."

[0070] 7, when the heating mode is set to the microwave mode and the heating output is set to any one of 600 W, 500 W, and 300 W, the setting screen SG displays a time setting key SKy1 for "5 minutes," a time setting key SKy2 for "1 minute," and a time setting key SKy3 for "10 seconds." In this case, the upper limit of the heating time that can be set on the setting screen SG is "30 minutes."

[0071] 7, when the heating mode is set to the microwave mode, the heating output is set to 300 W, and steam is set to be generated in the heating chamber 4, the setting screen SG displays a time setting key SKy1 for "5 minutes," a time setting key SKy2 for "1 minute," and a time setting key SKy3 for "10 seconds." In this case, the upper limit of the heating time that can be set on the setting screen SG is "15 minutes."

[0072] 7, when the heating mode is set to the microwave mode and the heating output is set to 150 W, the setting screen SG displays a "1 hour" time setting key SKy6, a "5 minute" time setting key SKy1, a "1 minute" time setting key SKy2, and a "30 seconds" time setting key SKy5. In this case, the upper limit of the heating time that can be set on the setting screen SG is "5 hours."

[0073] 7, when the heating mode is set to the double-sided grill mode or the top-side grill mode, the setting screen SG displays a "10 minutes" time setting key SKy4, a "1 minute" time setting key SKy2, and a "30 seconds" time setting key SKy5. In this case, the upper limit of the heating time that can be set on the setting screen SG is "30 minutes."

[0074] 7, when the heating mode is set to the lower grill mode, the setting screen SG displays a "10 minutes" time setting key SKy4, a "1 minute" time setting key SKy2, and a "30 seconds" time setting key SKy5. In this case, the upper limit of the heating time that can be set on the setting screen SG is "10 minutes."

[0075] 7, when the heating mode is set to the steam mode, the setting screen SG displays a "10 minutes" time setting key SKy4, a "1 minute" time setting key SKy2, and a "30 seconds" time setting key SKy5. In this case, the upper limit of the heating time that can be set on the setting screen SG is "30 minutes."

[0076] 7, when the heating mode is set to the oven mode and the heating temperature is set between 70° C. and 110° C., the setting screen SG displays a time setting key SKy6 for "1 hour," a time setting key SKy4 for "10 minutes," a time setting key SKy2 for "1 minute," and a time setting key SKy5 for "30 seconds." In this case, the upper limit of the heating time that can be set on the setting screen SG is "4 hours."

[0077] 7, when the heating mode is set to the oven mode and the heating temperature is set between 120° C. and 300° C., the setting screen SG displays a time setting key SKy6 for "1 hour," a time setting key SKy4 for "10 minutes," a time setting key SKy2 for "1 minute," and a time setting key SKy5 for "30 seconds." In this case, the upper limit of the heating time that can be set on the setting screen SG is "2 hours."

[0078] 7, when the heating mode is set to the fermentation mode, the setting screen SG displays a time setting key SKy6 for "1 hour," a time setting key SKy4 for "10 minutes," a time setting key SKy2 for "1 minute," and a time setting key SKy5 for "30 seconds." In this case, the upper limit of the heating temperature that can be set on the setting screen SG is "8 hours."

[0079] In the table of FIG. 7, the following rules apply to the combination of the time setting keys SKy. In the microwave oven mode, when the heating output is set to the maximum output of 800W, the setting screen SG does not display the "5 minutes" time setting key SKy1, which is displayed when other heating output settings are used. This is because the heating time that can be set with the time setting key SKy1 is close to the maximum heating time of 800W. If the time setting key SKy1 is displayed when setting 800W, an operation error may cause the heating time to reach the upper limit unintentionally, and the heating time must be reset. Therefore, in this embodiment, in order to widen the time span between the maximum heating time and the longest time that can be set with one operation, the "5 minutes" time setting key SKy1 is not displayed when the heating output is set to the maximum output of 800W.

[0080] In addition, in the microwave oven mode, when the heating output is set to the minimum output of 150 W, the setting screen SG displays the time setting key SKy6 for "1 hour," which is not displayed for other heating output settings. This is because heating at the minimum output is expected to take a relatively long time.

[0081] Also, in microwave mode, when the heating output is set to the minimum output of 150W, the shortest time that can be set with one operation on the setting screen SG is "30 seconds." That is, the setting key Sky that can set the shortest time at settings other than 150W is the time setting key SKy3 with "10 seconds," whereas at 150W, the setting key Sky that can set the shortest time is the time setting key SKy5 with "30 seconds." This is because when heating at the minimum output, heating for a relatively long time is expected.

[0082] Also, in microwave mode, the longest time that can be set with one operation of the time setting key SKy, which can be set in minutes, is 5 minutes, whereas in modes other than microwave mode, the longest time that can be set with one operation of the time setting key SKy, which can be set in minutes, is 10 minutes. That is, in microwave mode, the time setting key SKy1 for "5 minutes" is displayed, but in heating modes other than microwave mode, the time setting key SKy4 for "10 minutes" is displayed instead of the time setting key SKy1 for "5 minutes." This is because heating for a relatively long period of time is expected in heating modes other than microwave mode.

[0083] In the table of FIG. 7, the combination of the time setting keys SKy is the same regardless of the heating temperature, but the combination of the time setting keys SKy displayed on the setting screen SG may be a combination according to the heating temperature. For example, when the heating mode is set to oven mode and the heating temperature is set between 70°C and 110°C, the setting screen SG may not display the "30 seconds" time setting key SKy5, but may display the "1 hour" time setting key SKy6, the "10 minutes" time setting key SKy4, and the "1 minute" time setting key SKy2.

[0084] In addition, in the table of FIG. 7, the combination of the time setting keys SKy is the same regardless of the heating degree, but the combination of the time setting keys SKy displayed on the setting screen SG may be a combination according to the heating degree. For example, when the heating mode is set to the oven mode, the heating temperature is set between 70°C and 110°C, and the heating degree is set to "weak", the setting screen SG may display a time setting key SKy6 for "1 hour", a time setting key SKy4 for "10 minutes", and a time setting key SKy2 for "1 minute". Furthermore, when the heating mode is set to the oven mode, the heating temperature is set between 70°C and 110°C, and the heating degree is set to "standard", the setting screen SG may display the combinations in the table of Fig. 7. Furthermore, when the heating mode is set to the oven mode, the heating temperature is set between 70°C and 110°C, and the heating degree is set to "strong", the setting screen SG may display a time setting key SKy6 for "1 hour", a time setting key SKy4 for "10 minutes", a time setting key SKy2 for "1 minute", and a time setting key SKy4 for "10 seconds".

[0085] In addition, in the table of FIG. 7, the upper limit of the heating time is the same regardless of the heating degree, but the upper limit of the heating time that can be set on the setting screen SG may be an upper limit according to the heating degree. For example, when the heating mode is set to the oven mode, the heating temperature is set between 70°C and 110°C, and the heating degree is set to "low", the upper limit of the heating time that can be set on the setting screen SG may be "5 hours". Furthermore, when the heating mode is set to the oven mode, the heating temperature is set between 70°C and 110°C, and the heating degree is set to "standard", the upper limit of the heating time that can be set on the setting screen SG may be "4 hours". Furthermore, when the heating mode is set to the oven mode, the heating temperature is set between 70°C and 110°C, and the heating degree is set to "high", the upper limit of the heating time that can be set on the setting screen SG may be "3 hours".

[0086] Returning to the explanation of the setting screen SG, if any of the settings of the heating temperature, heating output, and heating degree are changed on the setting screen SG, the set heating time may be reset to zero depending on the heating time set at the time of the change.

[0087] Fig. 8 is a diagram for explaining the setting screen SG. Fig. 8 shows an example of the setting screen SG relating to the setting of the oven mode.

[0088] The setting screen SG on the left in FIG. 8 is the setting screen SG when the third oven key OKy3 is operated. On the setting screen SG on the left in FIG. 8, the heating temperature is set to 110°C, and the heating time is set to "3 hours 45 minutes." According to the table in FIG. 7, when the heating temperature is 110°C, the upper limit of the heating temperature that can be set is "4 hours." Therefore, the heating time of "3 hours 45 minutes" does not exceed the upper limit in the example in FIG. 8.

[0089] The setting screen SG on the right in FIG. 8 shows a case where the first temperature setting key TKy1 is operated on the setting screen SG on the left in the same figure, and the heating temperature is changed to 120°C. According to the table in FIG. 7, when the heating temperature is 120°C, the upper limit of the heating temperature that can be set is "2 hours". Therefore, the heating time of "3 hours 45 minutes" set on the setting screen SG on the left in FIG. 8 exceeds the upper limit when the heating temperature is 120°C. Therefore, as shown in the setting screen SG on the right in FIG. 8, when the heating temperature is changed to 120°C, the heating time that was set is reset to zero.

[0090] Fig. 9 is a diagram for explaining the setting screen SG. Fig. 9 shows an example of the setting screen SG relating to the setting of the oven mode.

[0091] The setting screen SG on the left in FIG. 9 is the setting screen SG when the third oven key OKy3 is operated. In the setting screen SG on the left in FIG. 9, the heating temperature is set to 110°C, and the heating time is set to "1 hour 56 minutes." According to the table in FIG. 7, when the heating temperature is 110°C, the upper limit of the heating temperature that can be set is "4 hours." Therefore, the heating time of "1 hour 56 minutes" does not exceed the upper limit in the example in FIG. 9.

[0092] The setting screen SG on the right of FIG. 9 shows a case where the first temperature setting key TKy1 is operated on the setting screen SG on the left of the same figure, and the heating temperature is changed to 120°C. According to the table in FIG. 7, when the heating temperature is 120°C, the upper limit of the heating temperature that can be set is "2 hours". Therefore, the heating time of "1 hour 56 minutes" set on the setting screen SG on the left of FIG. 9 is less than the upper limit of the heating time when the heating temperature is 120°C. Therefore, as shown on the setting screen SG on the right of FIG. 9, when the heating temperature is changed to 120°C, the heating time is not reset to zero, and "1 hour 56 minutes" is maintained.

[0093] 8 and 9 show an example in which the heating temperature setting is changed, but the heating time may be maintained or reset to zero when the heating output and heating degree settings are changed as well. That is, when the heating output or heating degree setting is changed, if the heating time set before the change exceeds the upper limit corresponding to the changed setting, the set heating time is reset to zero. Also, when the heating output or heating degree setting is changed, if the heating time set before the change does not exceed the upper limit corresponding to the changed setting, the set heating time is maintained without being changed.

[0094] [1-2. Operation] Next, the operation of the heating device 1 of this embodiment will be described. FIG. 10 is a flowchart showing the operation of the heating device 1.

[0095] The operation shown in the flowchart of Fig. 10 is premised on the power supply of the heating device 1 being on. Furthermore, at the start of the operation shown in the flowchart of Fig. 10, the heating device 1 is not performing heating.

[0096] 10, the display control unit 102 determines whether or not the heating mode is set (step S1). When the reception unit 101 receives an operation to set the heating mode via the setting screen SG, the display control unit 102 makes an affirmative determination in step S1.

[0097] When it is determined that the heating mode is set (step S1: YES), the display control unit 102 displays the combination of the time setting keys SKy on the setting screen SG (step S2).

[0098] The combination displayed in step S2 is a combination according to the set heating mode and any of the default settings of the heating temperature, heating output, and heating degree. For example, when the microwave mode is set as the heating mode and the heating output is set to 600 W by default, the combination of the time setting key SKy displayed in step S2 is the combination shown in FIG.

[0099] When the combination of the time setting keys SKy is displayed, the display control unit 102 judges whether or not the time setting keys SKy have been operated (step S3). When the reception unit 101 has received the operation of the time setting keys SKy, the display control unit 102 makes a positive judgment in step S3.

[0100] When the display control unit 102 determines that the time setting key SKy has been operated (step S3: YES), it determines whether the set heating time is the maximum heating time (step S4). That is, in step S4, the display control unit 102 determines whether the heating time displayed in the heating time display area TA1 is the maximum heating time.

[0101] When the display control unit 102 determines that the set heating time is the maximum heating time (step S4: YES), the notification unit 103 notifies that the time setting key SKy has been operated beyond the upper limit (step S5).

[0102] On the other hand, if the display control unit 102 determines that the set heating time is not the maximum heating time (step S4: NO), it determines whether the heating time added with the time of the operated time setting key SKy exceeds the maximum heating time (step S6).

[0103] When the display control unit 102 determines that the added heating time exceeds the maximum heating time (step S6: YES), it sets the heating time to the maximum heating time (step S7). That is, in step S7, the display control unit 102 displays the maximum heating time in the heating time display area TA1.

[0104] On the other hand, when the display control unit 102 determines that the added heating time does not exceed the maximum heating time (step S5: NO), it sets the time of the operated time setting key SKy to the added heating time (step S8). That is, in step S8, the display control unit 102 displays the heating time to which the time of the operated time setting key SKy is added in the heating time display area TA1.

[0105] Returning to the explanation of step S2, if the display control unit 102 determines that the time setting key SKy has not been operated (step S3: NO), it determines whether any of the settings of the heating temperature, heating output, and heating degree has been changed (step S9).

[0106] When the display control unit 102 determines that any of the settings of the heating temperature, the heating output, and the heating degree has not been changed (step S9: NO), the display control unit 102 shifts the process to step S13.

[0107] If the display control unit 102 determines that any of the settings of the heating temperature, heating output, and heating degree has been changed (step S9: YES), it determines whether the set heating time exceeds the maximum heating time corresponding to the changed setting (step S10).

[0108] If the display control unit 102 determines that the maximum heating time corresponding to the changed settings will not be exceeded (step S10: NO), it does not change the set heating time and displays the combination of time setting keys SKy corresponding to the changed settings (step S11).

[0109] On the other hand, if the display control unit 102 determines that the maximum heating time corresponding to the changed settings will be exceeded (step S10: YES), it resets the set heating time to zero and displays the combination of time setting keys SKy corresponding to the changed settings (step S12).

[0110] Returning to the explanation of step S8, the heating control unit 104 determines whether or not to start heating (step S13). When the reception unit 101 receives an operation of the start switch 53, the heating control unit 104 makes an affirmative determination in step S13.

[0111] When the heating control unit 104 determines not to start heating (step S13: NO), the processor 100 returns the process to step S3. On the other hand, when the heating control unit 104 determines to start heating (step S13: YES), the heating control unit 104 starts heating (step S14).

[0112] [1-3. Effects, etc.] As described above, the heating device 1 that heats an object to be heated includes the touch panel 54 that displays the time setting keys SKy for setting the heating time of the heating device 1, and the display control unit 102 that controls the touch panel 54. The display control unit 102 causes the touch panel 54 to display a combination of the time setting keys SKy corresponding to any one of the settings of the heating temperature of the heating device 1, the heating output of the heating device 1, and the heating degree of the object to be heated for each heating mode.

[0113] According to this, the combination of the time setting key SKy can be changed for each heating mode according to the setting of any one of the heating temperature, heating output, and heating degree. Therefore, the number of times the time setting key SKy is operated until the desired heating time is set can be reduced, and the user's effort in setting the heating time can be reduced. Therefore, the user's convenience in setting the heating time can be improved.

[0114] The heating time that can be set by the time setting key SKy has an upper limit according to the setting of the heating temperature, the heating output, or the heating degree for each heating mode. When the heating time set by the time setting key SKy exceeds the upper limit, the display control unit 102 sets the heating time to the upper limit and notifies the user that the time setting key has been operated to exceed the upper limit.

[0115] According to this, even if a heating time setting that exceeds the upper limit is performed, the set heating time is not reset to zero. Therefore, the possibility of insufficient heating due to an operation error can be reduced, and user convenience can be further improved. In addition, by notifying the user when a heating time setting that exceeds the upper limit is performed, the user can know whether or not an operation that exceeds the upper limit has been performed, and user convenience in setting the heating time can be further improved.

[0116] The heating time that can be set by the time setting key SKy has an upper limit according to the setting of any one of the heating temperature, heating output, and heating degree for each heating mode. When the setting of any one of the heating temperature, heating output, and heating degree is changed while the heating time is set, if the set heating time exceeds the upper limit corresponding to the changed setting, the display control unit 102 resets the set heating time to zero.

[0117] According to this, when any of the settings of the heating temperature, the heating output, and the heating degree is changed and the set heating time exceeds the upper limit corresponding to the changed setting, the user can understand that the heating time needs to be reset. Therefore, when any of the settings of the heating temperature, the heating output, and the heating degree is changed and the set heating time exceeds the upper limit corresponding to the changed setting, the possibility that the user can correctly set the desired heating time can be increased. Therefore, even if such a case occurs, it is possible to prevent the occurrence of a situation in which heating is performed unintentionally by the user.

[0118] When the heating time is set and any of the heating temperature, heating output, and heating degree settings is changed, the display control unit 102 does not change the set heating time unless the set heating time exceeds the upper limit corresponding to the changed setting.

[0119] According to this, if the set heating temperature does not exceed the upper limit corresponding to the changed setting, the set heating time is maintained. Therefore, after changing any of the settings of the heating temperature, heating output, and heating degree, it is not necessary to reset the heating time from 0 seconds. Therefore, even after changing any of the settings of the heating temperature, heating output, and heating degree, the user's effort in setting the heating time can be reduced. Therefore, the user's convenience in setting the heating time can be further improved.

[0120] When the heating mode is the microwave mode, one heating output can be set from among a plurality of different heating outputs. The combination of time setting keys Sky displayed when the set heating output is the minimum output includes a time setting key Sky that can set a longer time than any of the time setting keys SKy displayed when a heating output other than the minimum output is set.

[0121] This reduces the number of times the time setting key SKy needs to be operated to set the desired heating time, even when the minimum output is used and a relatively long heating time is required, thereby reducing the user's effort in setting the heating time. This further improves the user's convenience in setting the heating time.

[0122] When the heating mode is the microwave oven mode, one heating output can be set from among a plurality of different heating outputs. The shortest time that can be set by the time setting key SKy that is displayed when the set heating output is the minimum output is longer than the shortest time that can be set by the time setting key SKy that is displayed when a heating output other than the minimum output is set.

[0123] This reduces the number of times the time setting key SKy needs to be operated to set the desired heating time, even when the minimum output is used and a relatively long heating time is required, thereby reducing the user's effort in setting the heating time. This further improves the user's convenience in setting the heating time.

[0124] The heating time that can be set by the time setting key SKy has an upper limit according to the heating output setting. When the heating mode is the microwave mode, one heating output can be set from among a plurality of different heating outputs. The longest time that can be set by one operation of the time setting key SKy, which is displayed when the set heating output is the maximum output, is shorter than the longest time that can be set by one operation of the time setting key SKy, which is displayed when a heating output other than the maximum output is set.

[0125] This can prevent the heating time from unintentionally reaching the upper limit, which can lead to the need to reset the heating time, thereby improving the user's convenience in setting the heating time.

[0126] The longest time that can be set by one operation of the time setting keys SKy that are set in minutes and that are displayed when the heating mode is set to a mode other than the microwave oven mode is longer than the longest time that can be set by one operation of the time setting keys SKy that are set in minutes and that are displayed when the heating mode is set to the microwave oven mode.

[0127] This allows the number of times the time setting key SKy needs to be operated to set the desired heating time to be reduced, even in other heating modes where a relatively longer heating time is expected to be set than in the microwave oven mode, and reduces the user's effort in setting the heating time. This further improves the user's convenience in setting the heating time.

[0128] A method of controlling the heating device 1 for heating an object to be heated includes displaying, for each heating mode, a combination of time setting keys SKy for setting the heating time of the heating device 1 according to any one of the settings of the heating temperature of the heating device 1, the heating output of the heating device 1, and the heating degree of the object to be heated.

[0129] This provides the same effects as those of the heating device 1 described above.

[0130] The control program 111 causes the processor 100 of the heating device 1 that heats the object to display, on the touch panel 54, a time setting key SKy for setting a heating time of the heating device 1. The control program 111 causes the processor 100 to display, on the touch panel 54, a combination of the time setting keys SKy corresponding to any one of the settings of the heating temperature of the heating device 1, the heating output of the heating device 1, and the heating degree of the object to be heated, for each heating mode.

[0131] This provides the same effects as those of the heating device 1 described above.

[0132] (Embodiment 2) Next, a second embodiment will be described. [2-1. Configuration] The second embodiment differs from the first embodiment in that the memory 110 stores the following information: That is, the memory 110 of the second embodiment stores the heating time previously set by the user for each heating mode, heating temperature, heating output, and heating degree. In the second embodiment, the memory 110 is an example of the "predetermined area."

[0133] The memory 110 may store only the latest heating time among the heating times previously set for each heating mode, heating temperature, heating output, and heating degree. The memory 110 may also store a plurality of heating times including the latest heating time among the heating times previously set for each heating mode, heating temperature, heating output, and heating degree.

[0134] [2-2. Operation] Next, an operation of the heating device 1 in the embodiment 2 will be described. The embodiment 2 is different from the embodiment 1 in the operation of the display control unit 102 related to the display of the time setting key SKy. Other operations of the heating device 1 are the same as those in the embodiment 1.

[0135] When any one of the heating mode, heating temperature, heating output, and heating degree is set, the display control unit 102 acquires a heating time corresponding to any one of the set heating mode, heating temperature, heating output, and heating degree from the memory 110. Then, the display control unit 102 displays a combination of the time setting keys SKy that can minimize the number of operations for the acquired heating time.

[0136] For example, the memory 110 stores a heating time of "20 minutes" for a heating output of 500 W. In this example, when the heating output is set to 500 W, the display control unit 102 obtains the heating time of "20 minutes" from the memory 110. In the first embodiment, when the heating output is set to 500 W, following the table in FIG. 7, a time setting key SKy1 for "5 minutes," a time setting key SKy2 for "1 minute," and a time setting key SKy3 for "10 seconds" are displayed. However, the display control unit 102 in this embodiment displays a combination including a time setting key SKy4 for "10 minutes."

[0137] [2-3. Effects, etc.] As described above, the display control unit 102 acquires a heating time corresponding to any one of the settings of the heating mode, heating temperature, heating output, and heating degree from the memory 110, which stores the heating times previously set for each heating mode, heating temperature, heating output, and heating degree, and causes the touch panel 54 to display a combination of the time setting keys SKy corresponding to the acquired heating time.

[0138] This allows the display of a combination of time setting keys SKy that can reduce the number of operations for heating times previously set by the user, thereby reducing the user's effort in setting frequently used heating times and improving the user's convenience in setting heating times.

[0139] (Embodiment 3) Next, a third embodiment will be described. [3-1. Configuration] The third embodiment differs from the second embodiment in that the memory 110 stores the heating time described in the second embodiment for each user. That is, the memory 110 in the third embodiment stores the heating time previously set for each user for each heating mode, heating temperature, heating output, and heating degree. In the third embodiment, the memory 110 is an example of the "predetermined area."

[0140] FIG. 11 is a block diagram showing the configuration of a control system of heating device 1 in embodiment 3. As shown in FIG. As is clear from a comparison of Figures 11 and 3, embodiment 3 differs from the above-described embodiments in that the processor 100 further functions as a determination unit 105 by reading and executing a control program 111.

[0141] The identification unit 105 identifies who the user of the heating device 1 is. For example, when the reception unit 101 receives an operation to select a user via the operation panel 5, the identification unit 105 identifies that the user of the heating device 1 is the user selected by the operation received by the reception unit 101. Furthermore, the identification unit 105 identifies who the user of the heating device 1 is by biometric authentication such as fingerprint, retina, face, or voice. In the latter example of the identification method, biometric features related to biometric authentication are registered in the heating device 1. In the latter example of the identification method, the heating device 1 is equipped with devices related to biometric authentication such as a capacitive panel, a camera, and a microphone.

[0142] When the identification unit 105 identifies who the user is, the identification unit 105 outputs user information indicating who the user is to the display control unit 102 .

[0143] [3-2. Operation] Next, an operation of the heating device 1 in the embodiment 3 will be described. The embodiment 3 is different from the embodiments 1 and 2 in the operation of the display control unit 102 related to the display of the time setting key SKy. Other operations of the heating device 1 are the same as those in the embodiment 1.

[0144] When any one of the heating mode, heating temperature, heating output, and heating degree is set, the display control unit 102 acquires from the memory 110 a heating time of the user indicated by the user information received from the identification unit 105 and corresponding to any one of the set heating mode, heating temperature, heating output, and heating degree. Then, the display control unit 102 displays a combination of the time setting keys SKy that can reduce the number of operations the most for the acquired heating time.

[0145] [3-3. Effects, etc.] As described above, the memory 110 stores the heating time previously set for each user. The display control unit 102 acquires the heating time corresponding to the user who uses the heating device 1 from the memory 110, and causes the touch panel 54 to display a combination of the time setting keys SKy corresponding to the acquired heating time.

[0146] This allows a combination of time setting keys SKy that can reduce the number of operations for the heating time previously set by the user to be displayed for each user, thereby improving the convenience of setting the heating time for each user.

[0147] (Other embodiments) As described above, the above-mentioned first, second and third embodiments have been described as examples disclosed in the present application. However, the technology in the present disclosure is not limited to these, and can be applied to embodiments in which modifications, substitutions, additions, omissions and the like are made. In addition, it is also possible to combine the components described in the above-mentioned first, second and third embodiments to form new embodiments. Therefore, other embodiments will be exemplified below.

[0148] In the above-described embodiment, the operation of the time setting key SKy exceeding the maximum heating time is notified by voice, but the manner of notification is not limited to voice and may be other manners such as display or information transmission.

[0149] In other embodiments, together with the time setting key SKy, a reset key for resetting the heating time displayed in the heating time display area TA1 to zero, or a key for setting the heating time displayed in the heating time display area TA1 to an arbitrary time may be displayed.

[0150] In the above-described second and third embodiments, the heating time is acquired from the memory 110, but if the heating device 1 is capable of communicating with a server connected to a network, the display control unit 102 may acquire the heating time from the server. In this configuration, the memory 110 does not need to store the heating time. Also, in this configuration, the server stores the heating time in the same manner as the storage manner described in the second and third embodiments. In this alternative embodiment, the server is an example of a "storage area."

[0151] The above-mentioned embodiment is configured to have at least a microwave mode, a grill mode, a steam mode, an oven mode, and a fermentation mode as heating modes. In other embodiments, the heating mode may be configured to have one or more of these five modes. In this configuration, the heating unit 11 does not need to have all the mechanisms described in the above-mentioned embodiment, and only needs to have a mechanism corresponding to the type of heating mode to be provided.

[0152] In the embodiment described above, the number of types of time setting keys SKy displayed is six. In other embodiments, the number of types of time setting keys SKy displayed may be more or less as long as the added times are different from one another.

[0153] In the above-described embodiment, a configuration is provided in which a "5 minute" time setting key SKy1, a "1 minute" time setting key SKy2, a "10 second" time setting key SKy3, a "10 minute" time setting key SKy4, a "30 second" time setting key SKy5, and a "1 hour" time setting key SKy6 are displayed. However, the times added by these time setting keys SKy are merely examples, and are not limited to 5 minutes, 1 minute, 10 seconds, 10 minutes, 30 seconds, and 1 hour.

[0154] In the above-described embodiment, the heating device 1 is configured to include the touch panel 54. In the above-described embodiment, the time setting key SKy is a key displayed on the touch panel 54, and is a software key that can be operated by a user by touching. In another embodiment, the heating device 1 may include a display without a touch function instead of the touch panel 54. In this other embodiment, the display of the heating device 1 displays the time setting key SKy that can be operated by a switch that is not a software switch.

[0155] In other embodiments related to the above-mentioned second and third embodiments, when the heating time cannot be obtained from the memory 110, the combination of the time setting keys SKy described in the first embodiment may be displayed.

[0156] The control program 111 of the above-described embodiment can also be non-temporarily recorded on a recording medium that is readable by the processor 100, for example. As the recording medium, a magnetic or optical recording medium or a semiconductor memory device can be used. In addition, the control program 111 can be stored in a server device or the like, and the heating device 1 can download the control program 111 from the server device to realize the above-described operation.

[0157] The processor 100 may be composed of a single processor or multiple processors. The processor 100 may be hardware programmed to realize corresponding functional units. That is, these processors may be composed of, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0158] The configuration of the heating device 1 shown in Fig. 3 and Fig. 11 is an example, and the specific implementation form is not particularly limited. In other words, it is not necessarily required to implement hardware corresponding to each part individually, and it is also possible to implement a configuration in which one processor executes a program to realize the functions of each part. Also, some of the functions realized by software in the above-mentioned embodiment may be hardware, or some of the functions realized by hardware may be software.

[0159] The step units of the operation shown in Fig. 10 are divided according to the main processing contents in order to facilitate understanding of the operation, and the operation is not limited by the manner in which the processing units are divided or the names thereof. The operation may be divided into more step units according to the processing contents. Also, one step unit may be divided so as to include more processing. Also, the order of the steps may be changed as appropriate within the scope of the present disclosure.

[0160] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents.

[0161] (Additional Note) The above description of the embodiments discloses the following techniques.

[0162] (Technology 1) A heating device for heating an object to be heated, comprising: a display unit that displays a time setting key for setting a heating time of the heating device; and a display control unit that controls the display unit, wherein the display control unit causes the display unit to display a combination of the time setting keys corresponding to any one of the settings of the heating temperature of the heating device, the heating output of the heating device, and the heating degree of the object to be heated, for each heating mode. According to this, the combination of the time setting keys can be changed for each heating mode depending on the setting of the heating temperature, heating output, or heating degree. Therefore, the number of times the time setting keys need to be operated to set the desired heating time can be reduced, and the user's effort in setting the heating time can be reduced. Therefore, the user's convenience in setting the heating time can be improved.

[0163] (Technology 2) The heating device according to Technology 1, wherein the heating time that can be set by the time setting key has an upper limit according to any one of the settings of the heating temperature, the heating output, and the heating degree for each heating mode, and when the heating time set by the time setting key exceeds the upper limit, the display control unit sets the heating time to the upper limit and notifies the user that the time setting key has been operated in a manner that exceeds the upper limit. According to this, even if a heating time setting that exceeds the upper limit is performed, the set heating time is not reset to zero. Therefore, the possibility of insufficient heating due to an operation error can be reduced, and user convenience can be further improved. In addition, by notifying the user when a heating time setting that exceeds the upper limit is performed, the user can know whether or not an operation that exceeds the upper limit has been performed, and user convenience in setting the heating time can be further improved.

[0164] (Technology 3) The heating device according to Technology 1 or Technology 2, wherein the heating time settable by the time setting key has an upper limit corresponding to any one of the settings of the heating temperature, the heating output, and the heating degree for each heating mode, and when any one of the settings of the heating temperature, the heating output, and the heating degree is changed while the heating time is set, the display control unit resets the set heating time to zero if the set heating time exceeds the upper limit corresponding to the changed setting. According to this, when any of the settings of the heating temperature, the heating output, and the heating degree is changed and the set heating time exceeds the upper limit corresponding to the changed setting, the user can understand that the heating time needs to be reset. Therefore, when any of the settings of the heating temperature, the heating output, and the heating degree is changed and the set heating time exceeds the upper limit corresponding to the changed setting, the possibility that the user can correctly set the desired heating time can be increased. Therefore, even if such a case occurs, it is possible to prevent the occurrence of a situation in which heating is performed unintentionally by the user.

[0165] (Technology 4) The heating device according to Technology 3, wherein when the heating time is set and any of the heating temperature, the heating output, and the heating degree is changed, the display control unit does not change the set heating time unless the set heating time exceeds the upper limit corresponding to the changed setting. According to this, if the set heating temperature does not exceed the upper limit corresponding to the changed setting, the set heating time is maintained. Therefore, after changing any of the settings of the heating temperature, heating output, and heating degree, it is not necessary to reset the heating time from 0 seconds. Therefore, even after changing any of the settings of the heating temperature, heating output, and heating degree, the user's effort in setting the heating time can be reduced. Therefore, the user's convenience in setting the heating time can be further improved.

[0166] (Technology 5) The heating device described in any one of Technology 1 to Technology 4, wherein the display control unit acquires the heating time corresponding to any one of the settings of the heating mode, the heating temperature, the heating output, and the heating degree from a memory area that stores the heating time previously set for each of the heating mode, the heating temperature, the heating output, and the heating degree, and displays on the display unit the combination of the time setting keys corresponding to the acquired heating time. This allows the display of a combination of time setting keys that can reduce the number of operations for the heating times previously set by the user, thereby reducing the effort required by the user to set frequently used heating times and improving the user's convenience in setting the heating times.

[0167] (Technology 6) The heating device described in Technology 5, wherein the memory area stores the heating time previously set for each user, and the display control unit obtains from the memory area the heating time corresponding to the user who uses the heating device, and causes the display unit to display the combination of time setting keys corresponding to the obtained heating time. This allows a combination of time setting keys that can reduce the number of operations for the heating time previously set by the user to be displayed for each user, thereby improving the convenience of setting the heating time for each user.

[0168] (Technology 7) A heating device according to any one of Technology 1 to Technology 6, wherein when the heating mode is a microwave mode, one of a plurality of different heating outputs can be set to the heating output, and the combination of time setting keys displayed when the set heating output is the minimum output includes a time setting key capable of setting a longer time than any of the time setting keys displayed when the heating output other than the minimum output is set. This reduces the number of times the time setting key needs to be operated to set the desired heating time, even when the minimum output is used and a relatively long heating time is expected, and reduces the user's effort in setting the heating time. This improves the user's convenience in setting the heating time.

[0169] (Technology 8) A heating device according to any one of Technology 1 to Technology 7, wherein when the heating mode is a microwave mode, one of a plurality of different heating outputs can be set, and the shortest time that can be set by the time setting key that is displayed when the set heating output is the minimum output is longer than the shortest time that can be set by the time setting key that is displayed when a heating output other than the minimum output is set. This reduces the number of times the time setting key needs to be operated to set the desired heating time, even when the minimum output is used and a relatively long heating time is expected, and reduces the user's effort in setting the heating time. This improves the user's convenience in setting the heating time.

[0170] (Technology 9) A heating device according to any one of Technology 1 to Technology 7, wherein the heating time that can be set by the time setting key has an upper limit according to the setting of the heating output, and when the heating mode is a microwave mode, one of a plurality of heating outputs that are different from each other can be set to the heating output, and the longest time that can be set by one operation of the time setting key that is displayed when the set heating output is the maximum output is shorter than the longest time that can be set by one operation of the time setting key that is displayed when a heating output other than the maximum output is set. This can prevent the heating time from unintentionally reaching the upper limit, which can lead to the need to reset the heating time, thereby improving the user's convenience in setting the heating time.

[0171] (Technology 10) A heating device described in any one of Technology 1 to Technology 9, wherein the longest time that can be set by a single operation of the time setting key, which is set in minutes, among the time setting keys that are displayed when the heating mode is set to a mode other than a microwave mode, is longer than the longest time that can be set by a single operation of the time setting key, which is set in minutes, among the time setting keys that are displayed when the heating mode is set to a microwave mode. This reduces the number of times the time setting key needs to be operated to set the desired heating time, even in other heating modes where a relatively longer heating time is expected to be set than in the microwave mode, and reduces the user's effort in setting the heating time. This further improves the user's convenience in setting the heating time.

[0172] (Technology 11) A method for controlling a heating device that heats an object to be heated, the method displaying, for each heating mode, a combination of time setting keys for setting a heating time of the heating device according to any one of the settings of the heating temperature of the heating device, the heating output of the heating device, and the heating degree of the object to be heated. According to this, the same effect as that of the heating device described in the first technique can be achieved.

[0173] (Technology 12) A program that causes a processor of a heating device that heats an object to be heated to display on a display unit a combination of time setting keys for setting a heating time of the heating device according to any one of the settings of the heating temperature of the heating device, the heating output of the heating device, and the heating degree of the object to be heated, for each heating mode. According to this, the same effect as that of the heating device described in the first technique can be achieved. [Industrial Applicability]
