(Cooking)
The heating cooker 101 has a cooking mode (for example, curry mode, meat potato mode, cake mode, etc.) for executing cooking by heating for each menu. Each cooking mode is accompanied by a normal mode in which cooking is started at the same time as the start of the cooking mode, and a reservation mode in which reservation cooking is performed. The reserved cooking refers to cooking in which the cooking of the ingredients contained in the inner pot 3 is completed at the reserved time or after the reserved time. Each mode is configured to be selected by the user from the operation unit 25.

The control unit 17 controls the heating of the heating unit 15 according to the selected cooking mode. Further, the control unit 17 automatically controls the heating by controlling the heating of the heating unit 15 based on the detection results (detection values) of the temperature sensor 16, the weight sensor 18, and the steam sensor 27. By controlling the heating in this way, the cooking cooker 101 executes cooking according to the selected cooking mode.

Specifically, the control unit 17 controls heating by controlling switching between ON and OFF of energization of the heating unit 15. Since the control unit 17 controls the heating of the heating unit 15 based on the detection results of the temperature sensor 16, the weight sensor 18, and the water vapor sensor 27, more accurate control can be performed. By controlling the heating in this way, the cooking cooker 101 executes cooking according to the selected cooking mode. Further, the control unit 17 controls the heating of the heating unit 15 so that the heat is kept at a temperature higher than the temperature range in which the food is easily spoiled after the cooking is completed.

Further, the control unit 17 includes a timer unit (not shown), which manages the cooking time and enables reserved cooking.

In this way, since the cooking device 101 is a cooking device whose temperature can be easily controlled, not only stewed dishes such as meat potatoes and curry, but also fermented foods (yogurt, etc.) whose temperature control is difficult can be made, and noodles are boiled. As described above, since the water from the foodstuff in the inner pot 3 can be efficiently converted into steam and circulated, cooking without adding water or cooking with a small amount of water is also possible.

The reservation mode (first reservation mode) executed by the cooking cooker 101 will be described below.

FIG. 5 is a graph showing the relationship between the elapsed time in the first reservation mode and the temperature detected by the temperature sensor 16. When the first reservation mode is selected in the cooking cooker 101, as shown in FIG. 5, the control unit 17 has a temperature of 70 ° C. or higher inside the food material housed in the inner pot 3 at the start of the reservation mode. The first control for controlling the heating by the heating unit 15 is performed so that the period during which the temperature is increased is maintained for 1 minute or more. Here, the start time of the reservation mode means, in the present embodiment, immediately after the reservation, that is, immediately after the reservation button of the operation unit 25 for starting the reservation mode is pressed. In addition, in FIG. 5, as an example, the period of 100 ° C. is controlled so as to be maintained for 1 minute or more.

By performing the first control, the heating cooker 101 maintains the period in which the internal temperature of the food material in the inner pot 3 is 70 ° C. or higher for 1 minute or more at the start of the reservation mode, and thus adheres to or adheres to the food material. Most germs near foodstuffs can be sterilized. Therefore, it is possible to prevent the spoilage of the food material. Even if it takes a long time from the start of the reservation mode to the start of cooking, since the first control is performed at the start of the reservation, germs do not propagate and the spoilage of the food can be prevented.

Here, in FIG. 5, the period in which the temperature rises after the heat retention period of maintaining 70 ° C. is the cooking period. The reason for keeping the temperature at 70 ° C. before cooking in this way is, for example, to prevent the lid 2 from being opened during the reservation mode and the germs from breeding when the cooking device 101 is not provided with the lock mechanism. be. As shown in FIG. 5, such control may not be performed unless there is a situation in which various germs such as opening the lid after the period of 100 ° C. is maintained for 1 minute or more are not propagated. do not have. In FIG. 5, the temperature is kept at 70 ° C. as an example, but the heat may be kept at a higher temperature. The control of keeping the temperature at 70 ° C. before cooking is the same as the control described below with reference to FIG. 6 or FIG.

Further, in the first reservation mode, the control unit 17 controls the heating by the heating unit 15 so that the temperature of the food material contained in the inner pot 3 becomes 70 ° C. or higher at the end of the reservation mode. I do.

By performing the second control, it is possible to produce that the food is fresh (hot) and to provide the cooked food in a state that the user feels delicious.

Here, in the heating cooker 101, the temperature inside the food material in the inner pot 3 is indirectly determined by the temperature of the inner pot 3 detected by the temperature sensor 16, the weight of the food material detected by the weight sensor 18, and the heating time. And the temperature of the foodstuff in the inner pot 3 is detected. That is, the cooking device 101 stores data in which the temperature, weight, and heating time are associated with the temperature inside the food, and the temperature, weight, and heating time measured with reference to this data are used. , The temperature inside the food material in the inner pot 3 and the temperature of the food material in the inner pot 3 are detected. Of course, other methods may be used to detect the temperature inside the food material in the inner pot 3. The temperature of the food material may be the temperature on the surface of the food material or the temperature inside the food material.

Although the cooking of the food is performed between the first control and the second control, a part or all of the period of the first control or the period of the second control may overlap with the cooking period of the food.

When the temperature of the food is 70 ° C. or higher at the end of the reservation mode, the control unit 17 does not execute heating in the second control, that is, does not execute unnecessary heating. Energy saving can be achieved by such control.

In the third reservation mode, as shown in FIG. 7, in addition to the heating control in the first reservation mode, the control unit 17 has a period during which the surface temperature of the food material becomes 50 to 60 ° C. before the first control. The pre-stage control for controlling the heating by the heating unit 15 is performed so that the temperature is maintained for a predetermined time.

Here, when the foodstuff contains pectin, the period of 50 to 60 ° C. is maintained for a predetermined time, so that the action of the enzyme prevents the decomposition of the pectin and hardens the surface of the foodstuff. Therefore, by performing the pre-stage control before the first control, the surface of the food material can be hardened by containing pectin. Therefore, for example, when cooking meat potatoes using the third reservation mode, it is possible to prevent the potatoes from collapsing in the subsequent cooking by hardening the surface of the potatoes by the pre-stage control.

Here, the predetermined time for maintaining the period of 50 to 60 ° C. is set to be different depending on the cooking mode. In other words, the time for solidifying the appropriate surface is set according to the ingredients used in each menu.

In addition, since the temperature becomes 70 ° C. or higher in the first control, the surface of the food material cannot be hardened even if the period of 50 to 60 ° C. is maintained for a predetermined time thereafter.
