Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the cooking appliance of Patent Document 1 above, even when the user executes the same automatic cooking mode, it is necessary to manually set the additional baking time every time. Therefore, the user needs to remember the additional baking time that results in the preferred cooked result in each automatic cooking mode, and there is a problem of poor usability.

[0005] The present invention solves the above problems, and an object of the present invention is to improve the usability in the automatic cooking mode.

Means for Solving the Problems

[0006] According to the present invention, heating means for heating the food to be cooked; a heating setting input unit capable of inputting a heating setting of the heating means including an automatic cooking mode for automatically cooking the food to be cooked; When the automatic cooking mode is input in the heating setting input unit, if it is within the additional heating setting permission period provided within the automatic cooking time for automatically cooking the food to be cooked, the additional heating time setting unit allows setting an additional heating time for the automatic cooking time, A storage unit that stores the history of past additional heating times set in the additional heating time setting unit, A display unit that displays predetermined information, It comprises a control unit and, The control unit aggregates the frequency of setting each past additional heating time setting value stored in the memory unit. During the period in which additional heating settings are permitted, the cooking appliance is provided that displays past additional heating time settings in order of frequency of setting, prioritizing them on the display unit.

[0007] According to the above-mentioned cooking appliance, during the period when additional heating settings are permitted, past additional heating time settings are displayed in order of frequency, prioritizing those with the highest setting frequency. This allows users to easily set the additional heating time to achieve their desired cooking results. Therefore, users do not need to remember the additional heating time required for their desired cooking results, thus improving the usability of the automatic cooking mode.

[0008] Preferably, in the above-mentioned heating appliance, The additional heating time setting unit is configured to allow modification of the additional heating time, either extending or shortening it after the initial setting. The memory unit stores the history of the additional heating time after it has been changed.

[0009] With the above-mentioned cooking appliance, even after setting the additional heating time, it is possible to change the additional heating time by extending or shortening it. Therefore, even if the user has set the additional heating time incorrectly or wants to change the finished cooking result, the additional heating time can be corrected. Furthermore, with the above-mentioned cooking appliance, if the additional heating time is changed, the history of the changed additional heating time is stored in the memory unit, so the user does not need to remember the changed additional heating time. This further improves the usability of the automatic cooking mode.

[0010] Preferably, the above-mentioned heating appliance further includes: It has a temperature detection means for detecting the ambient temperature around the food being cooked or the temperature of the food being cooked, The memory unit stores the history of past additional heating times, along with the temperature characteristics detected by the temperature detection means during a predetermined determination period within the automatic cooking time. When automatic cooking is started, the control unit acquires the current temperature characteristics of the automatic cooking during the determination period. The memory unit stores the current automatic cooking temperature characteristics and the frequency of past additional heating time settings for each temperature characteristic. During the period when additional heating settings are permitted, the display will prioritize showing past additional heating time settings for the same temperature characteristics as the current automatic cooking setting, in order of frequency of setting.

[0011] By detecting the ambient temperature around the food being cooked or the temperature of the food being cooked, it is possible to understand differences in cooking conditions such as the size and quantity of the food being cooked from the temperature characteristics, such as the temperature rise and temperature gradient, over a certain period during automatic cooking. Furthermore, the finished dish will differ depending on the above temperature characteristics during automatic cooking. Therefore, when automatic cooking starts, the system acquires the current temperature characteristics of the automatic cooking during the judgment period, aggregates the frequency of past additional heating time settings that match the current temperature characteristics of the automatic cooking stored in the memory unit, and during the additional heating setting permission period, displays past additional heating time settings that match the current temperature characteristics of the automatic cooking in order of frequency, prioritizing them on the display unit. This allows the user to easily set the additional heating time to achieve their desired finished dish.

[0012] Preferably, in the above-mentioned heating appliance, If the control unit has multiple additional heating time settings with the same frequency but different values ​​stored in the memory unit, it will prioritize displaying the newer additional heating time setting on the display unit.

[0013] According to the above-mentioned cooking appliance, even with the same setting frequency, the most recent additional heating time setting is preferentially displayed on the display, allowing the user to easily set the additional heating time to match their recent preferred cooking results.

[0014] Preferably, in the above-mentioned heating appliance, The heating setting input section includes multiple automatic cooking modes. The memory unit stores the history of past additional heating times for each automatic cooking mode. The control unit aggregates the frequency of setting each past additional heating time setting for each automatic cooking mode stored in the memory unit. When one of several automatic cooking modes is selected in the heating setting input section, the display unit will prioritize displaying past additional heating time settings for the selected automatic cooking mode in order of frequency of use, during the additional heating setting permission period.

[0015] According to the above-mentioned cooking appliance, when one of several automatic cooking modes is selected, the past additional heating time settings for the selected automatic cooking mode are displayed on the display unit in order of frequency of selection during the additional heating setting permission period, thereby improving the usability of the automatic cooking modes.

[0016] Preferably, in the above-mentioned heating appliance, The control unit, after the additional heating setting permission period has started, displays the past additional heating time settings on the display unit in order of frequency of setting, for a predetermined selected time. If no additional heating time is set in the additional heating time setting section after the selected time has elapsed, the system will automatically set the additional heating time to the value that was set most frequently in the past.

[0017] According to the above-mentioned cooking appliance, even if the user forgets to set the additional heating time, the appliance will automatically set the additional heating time to match the user's preferred cooking result, thus improving the usability of the automatic cooking mode.

Mode for Carrying Out the Invention

[0019] (Embodiment 1) Hereinafter, the heating cooker according to the present embodiment will be described. Figure 1 is a schematic diagram showing the configuration of the heating cooker of the present embodiment applied to a grill device mounted on a gas stove. Although not shown, the grill device is incorporated in a housing having a plurality of stove burners on the top surface.

[0020] As shown in Figure 1, the grilling device 1 comprises a grill chamber (heating chamber) 3 having a front opening 2, and a grill door 4 that can be opened and closed to close the front opening 2 of the grill chamber 3. A shallow grill plate 6, which is a type of cooking utensil on which food to be cooked is placed, is housed inside the grill chamber 3. Alternatively, a grilling rack or a shallow or deep cooking container may be used as the cooking utensil.

[0021] Inside the grill compartment 3 are grill burners (heating means) 7 and 8 for heating food placed on the grill plate 6 from above and below. The ignition and extinction of the grill burners 7 and 8, as well as their heat output, are controlled by a grill controller 9, which will be described later.

[0022] The front of the housing (not shown) is provided with a grill burner on / off button 10 for instructing the on / off of the grill burners 7 and 8, a setting operation panel (heat setting input section) 11 for instructing the grill controller 9 to input various settings and heating settings for the grill burners 7 and 8, including automatic cooking modes, and a setting display panel (additional heating time setting section and display section) 12 for displaying various information, including automatic cooking modes, in response to instructions from the grill controller 9, and for instructing the grill controller 9 to set or change additional heating times. Although not shown, the setting operation panel 11 is provided with multiple automatic cooking menus that can be selected as automatic cooking modes for automatically cooking various foods such as grilled chicken thighs and grilled fish. The setting display panel 12 may be installed alongside the setting operation panel 11, or it may be installed separately on the top surface of the gas stove. Alternatively, the setting operation panel 11 and the setting display panel 12 may be installed as a single unit.

[0023] The grill burners 7 and 8 are ignited by grill burner ignition electrodes 13 and 14, respectively. The combustion state of the ignited grill burners 7 and 8 is detected by grill burner thermocouples 15 and 16. The grill chamber 3 is also equipped with a grill temperature sensor (temperature detection means) 17 for detecting the internal temperature of the grill chamber 3, which is the ambient temperature around the food being cooked. Alternatively, a temperature sensor may be provided in place of the grill temperature sensor 17, or together with the grill temperature sensor 17, that contacts the bottom surface of a cooking appliance such as a grill plate 6 to detect the temperature of the food being cooked. A non-contact infrared temperature sensor may also be provided.

[0024] Fuel gas is supplied to the grill burners 7 and 8 via the gas supply pipe 18. The gas supply pipe 18 is equipped with grill burner main gas valves 19 and 20 and grill burner gas volume control valves 21 and 22, which switch between supplying and shutting off fuel gas to the grill burners 7 and 8 respectively.

[0025] The grill controller 9 consists of an electronic unit such as a microcomputer and includes a memory unit 23 and a timer 24. The grill controller 9 receives signals from the grill burner ignition / extinguishing buttons 10, signals from the setting operation panel 11 and setting display panel 12, temperature detection signals from the grill temperature sensor 17, and combustion state detection signals from each thermocouple 15 and 16. Although not shown, LED lamps and a buzzer are also connected to the grill controller 9.

[0026] Furthermore, the grill controller 9 includes, as a functional unit for performing operation, a combustion control unit 30 that controls the combustion of the grill burners 7 and 8, a cooking time setting unit 31 that sets various cooking times, a display control unit 32 that controls the display of various information to be shown on the setting display panel 12, a registration control unit 33 that stores the history of additional heating time for each automatic cooking mode in the storage unit 23 when the automatic cooking time ends, and an aggregation unit 34 that aggregates the setting frequency for each past additional heating time setting value for each automatic cooking mode stored in the storage unit 23. Therefore, in this embodiment, these functional units of the grill controller 9 constitute the control unit.

[0027] The memory unit 23 stores a program for grill control, and the grill controller 9 operates by executing the grill control program based on the above input signals.

[0028] Furthermore, the memory unit 23 stores automatic cooking records for automatically cooking various foods in automatic cooking mode. The automatic cooking record consists of, for example, automatic cooking display data and grill control data including the heat output of the grill burners 7 and 8 and the automatic cooking time. In addition, the memory unit 23 stores a history of past additional heating times for each automatic cooking mode.

[0029] Next, with reference to Figures 2 to 4, the control operation of the grill device 1 in this embodiment in automatic cooking mode will be explained. In the following, we will explain the case where the memory unit 23 stores a certain number of records of the number of times the setting value for the additional heating time (including cases where the additional heating time is 0 minutes) has been set for each automatic cooking mode in predetermined time units (for example, 1-minute units) as a history of past additional heating times. When a user sets the additional heating time for the first time on the setting display panel 12 for a particular automatic cooking mode, the additional heating time change setting screen, which will be described later, is displayed first, and the user manually sets an arbitrary additional heating time, thereby storing the history of the additional heating time in the memory unit 23.

[0030] When the user selects and enters an automatic cooking mode (for example, grilled chicken thigh) on the setting operation panel 11 and performs the ignition operation using the grill burner ignition / extinguishing button 10, the grill control data corresponding to the entered automatic cooking mode is read from the memory unit 23, and the automatic cooking time is set (step S1). Then, the grill burners 7 and 8 are ignited, and the cooking timer that measures the automatic cooking time is started.

[0031] Next, the grill controller 9 automatically adjusts the heat output of the grill burners 7 and 8 in response to the temperature detection signal from the grill temperature sensor 17 and the combustion state detection signals from the thermocouples 15 and 16, and starts automatic cooking. Although not shown in the diagram, at this time, the setting display panel 12 displays image data and name data corresponding to the entered automatic cooking mode, as well as the remaining cooking time.

[0032] When the setting permission start time arrives a predetermined time (e.g., 30 seconds) before the end of the automatic cooking time set in the entered automatic cooking mode (Yes in step S2), the frequency of setting past additional heating time values ​​in the entered automatic cooking mode is tallied, and the setting display panel 12 switches to the additional heating time selection screen display shown in Figure 3 (step S3), and selection switches 120 for selecting additional heating time values ​​are displayed. In this embodiment, the selection switches 120 for the three most frequently set additional heating time values ​​from the past additional heating time values ​​of the entered automatic cooking mode (e.g., three selection switches for "additional 2 minutes", "additional 1 minute", and "additional 4 minutes") are displayed from top to bottom. At this time, if there are multiple different additional heating time values ​​with the same setting frequency, the selection switches 120 for the newer additional heating time values ​​are displayed higher up. Also, although not shown, by pressing the additional display switch 121 (e.g., the "+" switch), the selection switches 120 for the next most frequently set past additional heating time values ​​are displayed from top to bottom. Here, among the multiple past additional heating time settings, the settings with the highest frequency of setting are displayed higher up. However, the display format is not particularly restricted as long as the past additional heating time settings are displayed preferentially in order of frequency of setting. For example, settings with higher frequency may be displayed in a larger font, or the setting frequency may be displayed numerically. Alternatively, only the past additional heating time setting with the highest frequency of setting may be displayed preferentially, and each time the additional display switch 121 is pressed, the past additional heating time settings may be displayed sequentially according to their setting frequency. Furthermore, the additional display switch 121 may include, for example, a "-" switch, so that pressing it displays the settings in the reverse order compared to the "+" switch.

[0033] During the period allowing additional heating settings until automatic cooking is completed, if the user selects and inputs a setting value for one additional heating time using the selection switch 120 (Yes in step S4), the additional heating time is added to the automatic cooking time set in the entered automatic cooking mode (step S5), and the remaining cooking time with the additional heating time added (for example, if "additional 2 minutes" is selected and input, "2 minutes 30 seconds remaining") is displayed. This allows the user to recognize that the automatic cooking time will be extended by the selected additional heating time. Also, as shown in Figure 4, the setting display panel 12 switches to the additional heating time change setting screen display (step S6), and change setting switches 122 (for example, "+1 minute" switch or "-1 minute" switch) that extend or shorten the set additional heating time in predetermined time units (for example, 1 minute units) are displayed.

[0034] If the user operates the change setting switch 122 to extend or shorten the additional heating time before the automatic cooking is completed (step S7, Yes), the changed additional heating time is added to the automatic cooking time set in the entered automatic cooking mode (step S8), and the remaining cooking time is displayed (not shown). This allows the user to recognize that the automatic cooking time has been extended by the changed additional heating time. When the automatic cooking time with the added additional heating time has elapsed (step S9, Yes), the grill burners 7 and 8 are extinguished, and a buzzer sounds to indicate the end of cooking. If no additional heating time is set during the additional heating setting permission period (step S4, No), when the automatic cooking time set in the entered automatic cooking mode has elapsed (step S10, Yes), the grill burners 7 and 8 are extinguished, and a buzzer sounds to indicate the end of cooking.

[0035] Furthermore, once the automatic cooking time has elapsed (Yes in step S9 or S10), "1" is added to the history of the number of times the same additional heating time setting value as the final additional heating time in this automatic cooking is set, and this history is stored in the storage unit 23 along with the date (step S11). Note that the history of additional heating times to be stored in the storage unit 23 is not particularly limited as long as it includes data that allows for the aggregation of the setting frequency for each additional heating time setting value, and may, for example, be the additional heating time setting value itself.

[0036] As described in detail above, according to this embodiment, during the period when additional heating settings are permitted before the automatic cooking time ends, past additional heating time settings are displayed on the setting display panel 12 in order of frequency of setting, thus allowing the user to easily set the additional heating time to achieve their desired cooking result. Therefore, the user does not need to remember the additional heating time to achieve their desired cooking result, thus improving the usability of the automatic cooking mode.

[0037] Furthermore, according to this embodiment, even after setting the additional heating time, it is possible to change the additional heating time by extending or shortening it. Therefore, even if the user has mistakenly set the additional heating time or wants to change the finished cooking result, the additional heating time can be corrected. In addition, according to this embodiment, when the additional heating time is changed, the memory unit 23 stores the history of the changed additional heating time, so the user does not need to remember the addition or subtraction from the previous additional heating time. This further improves the usability of the automatic cooking mode.

[0038] Furthermore, according to this embodiment, even with the same setting frequency, the setting value for the newer additional heating time is displayed on the setting display panel 12, so the user can easily set the additional heating time to match their recently preferred cooking result.

[0039] Furthermore, according to this embodiment, when one of the multiple automatic cooking modes is selected, during the additional heating setting permission period, past additional heating time settings for the selected automatic cooking mode are displayed on the setting display panel 12 in order of frequency of selection, thereby improving the usability of the automatic cooking modes.

[0040] (Embodiment 2) This embodiment has the same configuration as Embodiment 1, except that the control operation of the automatic cooking mode is different. Therefore, only the parts that differ from the configuration of Embodiment 1 will be described, and the same components will be omitted from the description using the same reference numbers.

[0041] Figure 5 is a correlation diagram showing the correlation between the automatic cooking time of one automatic cooking mode and the internal temperature detected by the grill temperature sensor 17, and Figure 6 is a data table showing the frequency of setting the past additional heating time in one automatic cooking mode, classified by the temperature rise amount △T within a predetermined judgment period ts at the beginning of automatic cooking.

[0042] As shown in Figure 5, when automatic cooking starts, the internal temperature detected by the grill temperature sensor 17 gradually rises. However, differences in cooking conditions, such as the size and quantity of the food being cooked, can be understood from the temperature characteristics, such as the temperature rise and temperature gradient, over a certain period during automatic cooking. Furthermore, the finished dish will differ depending on the above temperature characteristics during automatic cooking. Therefore, for example, as shown in Figure 6, the temperature rise △T within the judgment period ts from the start of automatic cooking until a predetermined time has elapsed can be classified into multiple categories. By aggregating the frequency of past additional heating time settings set for automatic cooking with a certain range of temperature rise △T, the automatic cooking time can be extended to the same additional heating time as past additional heating times set for automatic cooking with the same range of temperature rise △T as the current automatic cooking, resulting in a dish that suits the user's preferences. The judgment period ts is not particularly limited as long as it is a certain period before the setting permission start time when the additional heating setting permission period begins. It may be the entire period before the setting permission start time, or it may be only a part of the period. Furthermore, in addition to the temperature rise ΔT during a predetermined judgment period ts, the temperature gradient during the predetermined judgment period ts, the time it takes for the internal temperature to rise to a predetermined temperature, and an overheat prevention temperature set according to the temperature rise ΔT can also be used as temperature characteristics. As mentioned above, the same temperature characteristics include not only cases where the temperature characteristics are exactly the same, but also cases where the temperature characteristics belong to the same classification when the temperature characteristics within the judgment period ts are classified into multiple categories.

[0043] Next, with reference to Figure 7, the control operation of the grill device 1 in this embodiment in automatic cooking mode will be described. In the following, similar to Embodiment 1, the case in which the memory unit 23 stores a certain number or more history of the number of times the setting value of the additional heating time has been set in the past for each temperature characteristic for one automatic cooking mode will be described.

[0044] When a user selects and enters an automatic cooking mode (for example, grilled chicken thigh) on the setting operation panel 11 and performs the ignition operation using the grill burner ignition / extinguishing button 10, the grill control data corresponding to the entered automatic cooking mode is read from the memory unit 23, and the automatic cooking time is set (step S31). Then, the grill burners 7 and 8 are ignited, and the cooking timer that measures the automatic cooking time is started.

[0045] When automatic cooking starts, the setting display panel 12 displays image data and name data corresponding to the input automatic cooking mode, as well as the remaining cooking time, similar to Embodiment 1. The grill controller 9 also acquires the temperature characteristics (e.g., temperature rise ΔT) during a predetermined determination period (e.g., 2 minutes from the start of automatic cooking) based on the temperature detection signal from the grill temperature sensor 17 (step S32).

[0046] Next, similar to Embodiment 1, when the setting permission start time arrives a predetermined time (for example, 30 seconds) before the end of the automatic cooking time set in the input automatic cooking mode (Yes in step S33), the frequency of setting past additional heating time values ​​with the same temperature characteristics as the acquired temperature characteristics is aggregated in the input automatic cooking mode, and the setting display panel 12 switches to the additional heating time selection screen display (step S34), and the selection switches 120 for the three most frequently set additional heating time values ​​(for example, three selection switches for "additional 2 minutes", "additional 1 minute", and "additional 4 minutes") are displayed from top to bottom.

[0047] During the period allowing additional heating settings until automatic cooking is completed, if the user selects and enters a setting value for one additional heating time using the selection switch 120 (Yes in step S35), the additional heating time is added to the automatic cooking time set in the entered automatic cooking mode (step S36), and the remaining cooking time with the additional heating time added (for example, if "additional 2 minutes" is selected and entered, "2 minutes 30 seconds remaining") is displayed. The setting display panel 12 also switches to display the additional heating time change setting screen (step S37), and change setting switches 122 (for example, "+1 minute" switch or "-1 minute" switch) are displayed to extend or shorten the set additional heating time in predetermined time units (for example, 1 minute units).

[0048] The control operations after the display of the additional heating time change setting screen (steps S38 to S42) are the same as those in Embodiment 1 (steps S7 to S14). In this embodiment, "1" is added to the history of the number of times the same additional heating time setting value as the final additional heating time for the current automatic cooking at the same temperature characteristics as the current automatic cooking, and this is stored in the storage unit 23 along with the date (step S42).

[0049] As described in detail above, according to this embodiment, when automatic cooking is started, the current temperature characteristics of the automatic cooking during the determination period are acquired, the frequency of setting past additional heating time values ​​with the same temperature characteristics as the current automatic cooking stored in the memory unit 23 is aggregated, and during the additional heating setting permission period, past additional heating time values ​​with the same temperature characteristics as the current automatic cooking are displayed on the setting display panel 12 in order of frequency of setting, so that the user can easily set the additional heating time to achieve their desired cooking result. This further improves the usability of the automatic cooking mode.

[0050] (Embodiment 3) This embodiment has the same configuration as Embodiment 1, except that the control operation of the automatic cooking mode is different. Therefore, only the parts that differ from the configuration of Embodiment 1 will be described, and the same components will be omitted from the description using the same reference numbers. In the following, similar to Embodiment 1, we will describe the case in which the memory unit 23 stores a certain number or more of history records of the number of times the setting value of the additional heating time has been set in the past for each automatic cooking mode in predetermined time units.

[0051] As shown in Figure 8, when a user selects and inputs an automatic cooking mode (for example, grilled chicken thigh) on the setting operation panel 11 and performs the ignition operation with the grill burner ignition / extinguishing button 10, the grill control data corresponding to the input automatic cooking mode is read from the memory unit 23 and the automatic cooking time is set (step S51). Then, the grill burners 7 and 8 are ignited and the cooking timer that measures the automatic cooking time is started.

[0052] When automatic cooking begins, the setting display panel 12 displays image data and name data corresponding to the entered automatic cooking mode, as well as the remaining cooking time, similar to Embodiment 1.

[0053] Next, similar to Embodiment 1, when the setting permission start time (Yes in step S52) is reached, which is a predetermined time (e.g., 30 seconds) before the end of the automatic cooking time set in the input automatic cooking mode, a notification buzzer is sounded to inform the user that it is possible to set an additional heating time (step S53), and a selection time timer is started to measure a predetermined selection time (e.g., 2 seconds). In addition, the frequency of setting additional heating time in the past in the input automatic cooking mode is tallied, and the setting display panel 12 switches to display the additional heating time selection screen (step S53), and the selection switches 120 for the three most frequently set additional heating time values ​​(e.g., three selection switches for "additional 2 minutes", "additional 1 minute", and "additional 4 minutes") are displayed from top to bottom. Then, when the user selects and sets one additional heating time setting value using the selection switch 120 within the selected time (Yes in step S54), the additional heating time is added to the automatic cooking time set in the entered automatic cooking mode (step S57), and the remaining cooking time with the additional heating time added (for example, if "additional 2 minutes" is selected and entered, "2 minutes 30 seconds remaining") is displayed. The setting display panel 12 also switches to the additional heating time change setting screen display (step S58), and change setting switches 122 (for example, "+1 minute" switch or "-1 minute" switch) are displayed to extend or shorten the set additional heating time in predetermined time units (for example, 1 minute units).

[0054] On the other hand, if no additional heating time is selected within the selected time (No in step S54, Yes in step S55), the setting value for the additional heating time with the highest setting frequency is automatically set and added to the automatic cooking time (step S56), and the setting display panel 12 switches to displaying the additional heating time change setting screen (step S58). At this time, a buzzer may be sounded to let the user know that the additional heating time has been automatically set. The control operations after the display of the additional heating time change setting screen (steps S59 to S62) are the same as those in Embodiment 1 (steps S7 to S9 and step S11).

[0055] In this embodiment, even if the user forgets to set the additional heating time, the additional heating time that matches the user's preferred cooking result is automatically set, thereby improving the usability of the automatic cooking mode.

[0056] (Other embodiments) (1) In the above embodiment, the history of the additional heating time for the automatic cooking is automatically stored in the memory unit when the automatic cooking is completed. However, since different users may set different additional heating times in the same automatic cooking mode, the history of the additional heating time for the automatic cooking may be stored in the memory unit only when the user performs a predetermined registration operation.

[0057] (2) In the above embodiment, a heating appliance applied to the grill device of a gas stove was described. However, in the present invention, a heater or induction heating coil may be used as a heating means instead of a grill burner. The present invention may also be applied to a heating appliance having a stove burner, heater or induction heating coil as heating means and a stove section that heats the food to be cooked placed above the heating means. In this case, a pot bottom temperature sensor that contacts the bottom surface of a cooking utensil such as a pot to detect the temperature of the food to be cooked can be used as a temperature detection means. The present invention may also be applied to single-function heating appliances such as ovens or grillers that do not have a stove section.

[0058] (3) In the above embodiment, the additional heating setting permission period is set to a certain period from the setting permission start time before the end of the automatic cooking time until the end of the automatic cooking time, but it may be any certain period before the end of the automatic cooking time.

[0059] (4) In the above embodiment, once the additional heating time has been set, it is possible to change the additional heating time until the automatic cooking is completed, but a predetermined period for allowing changes to the setting may be provided. [Explanation of Symbols]
