(Cooking operation of heating cooker 1)
The cooking operation in the fourth embodiment of the heating cooker 1 will be explained using FIG. 9. FIG. 9 is a flowchart showing the heating procedure.

During cooking in the heating cooker 1, the heating control unit 31 receives the signal and starts heating control.

Note that the first period of cooking in the heating cooker 1 is from the start of step S901 in FIG. 9 to the start of step S903, and the second period is from the start of step S903 in FIG. 9 to the end of step S904. The third period is from the start of step S905 to the end of step S906 in FIG.

In cooking in the heating cooker 1, when the instruction receiving unit 28 receives an instruction to start cooking from the user, the instruction receiving unit 28 transmits information on the instruction (for example, cooking time or cooking mode) to the heating control unit 31. . The heating control unit 31 sets a first time, a first temperature, and a second period from the received information. Note that before receiving the instruction to start cooking, the user replenishes the water tank 21 with water, and inserts the water tank 21 containing water into the water tank insertion portion 25.

In addition, in the heating cooker 1, the dial 52b does not rotate for a predetermined period of time (for example, 1 second) after receiving the cooking time setting from the user using the dial 52b (that is, the user does not change the cooking time setting). ) is configured to start cooking when That is, the configuration is not such that heating cooking is performed from the moment the dial 52b is rotated. This makes it possible to accurately match the cooking time to the set time specified by the user.

Next, upon receiving the cooking start instruction from the instruction receiving section 28, the heating control section 31 drives the steam supply section 20. As a result, the pump 23 is driven, and the water stored in the water tank 21 is supplied to the steam generation engine 24. The water is then heated by the heater of the steam generation engine 24, and the supply of steam into the cooking chamber 14 is started.

(Step S901)
The heating control unit 31 continues heating control within the cooking chamber 14 .

(Step S902)
The heating control unit 31 receives temperature information in the cooking chamber 14 measured by the temperature measuring unit 27 from the temperature measuring unit 27, and determines whether the temperature in the cooking chamber 14 is equal to or lower than a first temperature. If the temperature in the cooking chamber 14 is below the first temperature (NO in step S902), the heating control unit 31 drives either the upper heater 17 or the lower heater 18. More specifically, the heating control unit 31 drives the upper heater 17 and the lower heater 18 alternately for a certain period of time (for example, 10 seconds).

(Step S903)
If the temperature in the cooking chamber 14 is higher than the first temperature (YES in step S902), the heating control unit 31 stops driving the upper heater 17 or the lower heater 18, and the heating unit 10 of the cooking device 1 and the operation of the steam supply section 20 is not controlled. As a result, the heating section 10 and the steam supply section 20 stop operating.

(Step S904)
It is determined whether the elapsed time from the heating control stop is within the second period. If the elapsed time from the heating control stop is within the second period (YES in step S904), the heating control unit 31 continues to stop controlling the operation of the heating unit 10 and the steam supply unit 20.

If the elapsed time from the stop of the heating control is not within the second period (NO in step S904), the process moves to step S905.

(Step S905)
The heating control unit 31 restarts heating control.

(Step S906)
The heating control section 31 receives temperature information inside the cooking chamber 14 measured by the temperature measuring section 27 from the temperature measuring section 27, and determines whether the temperature inside the cooking chamber 14 is equal to or lower than a second temperature. If the temperature in the cooking chamber 14 is below the first temperature (NO in step S906), the heating control unit 31 drives either the upper heater 17 or the lower heater 18. More specifically, the heating control unit 31 drives the upper heater 17 and the lower heater 18 alternately for a certain period of time (for example, 10 seconds). If the temperature in the cooking chamber 14 is higher than the first temperature (YES in step S906), the cooking device 1 finishes cooking.
