  First, after the operation of the heating on / off key 7a of the operation unit 7a corresponding to the heating unit 5a, the heating unit 5a starts cooking to start cooking and presses an inadvertent key (for example, the operation unit 7) When the thermal power up key 7b, the thermal power down key 7c, or the timer time setting key 7d is pressed multiple times, or when a single key such as the thermal power up key 7b is continuously pressed for a certain time (such as 3 seconds)) Then, the abnormal display (for example, an error display such as “U16”) is blinked on the display units 12a, 12b, and 12c without stopping the heating. In this way, even with a key arranged on the top surface that is easy to perform inadvertent operations, heating during cooking can not be easily cut off and the user can be notified of the abnormal state of the key. In cooking that requires time management such as cooking by timer setting, it is possible to improve usability by adopting a configuration that does not easily stop the cooking operation.

  In addition, after the operation of the heating on / off key 7a of the operation unit 7 corresponding to the heating unit 5a, the heating unit 5a starts cooking by heating, for example, pressing the careless key during cooking, for example, the operation unit 7 Corresponding to the heating unit 5a for a state in which keys such as the thermal power up key 7b, the thermal power down key 7c, or the timer time setting key 7d are continuously pressed for a certain time (for example, 3 seconds), or in a multi-pressed state. When the key including the heating on / off key 7a is pressed, the heating is surely stopped, and while the pressing of the heating on / off key 7a is continued in this state, the corresponding heating unit in each of the display units 12a, 12b, 12c. An abnormal display (error display such as “U16”) is lit on the display unit (here, the display unit 12a corresponds to the heating unit 5a). As described above, in the key for turning on and off the input of heating energization, safety during cooking can be ensured by always stopping the heating. In addition, the display when the key is abnormal blinks when the key is abnormal when the heating is continued, and lights when the key is abnormal when the heating is stopped. In the case of a key abnormality due to spilling or inadvertent water adhesion, it is easy to identify the abnormal key, and it is easy to take measures such as wiping the upper surface of the key that is dirty due to spilling.

  In addition, as shown in FIG. 2, the operation unit 7 corresponding to the heating unit 5 a, the operation unit 11 corresponding to the heating unit 5 b, and the operation unit 10 corresponding to the heating unit 6 are independent for each heating unit. By performing the key detection, for example, when all three mouths are heated and cooking is performed, when a key abnormality including the heating on / off key 7a, 11a, 10b occurs, a key abnormality occurs. Since only the heating unit corresponding to the operation unit stops heating, the usability for cooking can be improved.

It is possible to further improve safety by prohibiting the operation of heating and energizing and setting the state in which the operation can be performed again by the corresponding operation unit of the corresponding heating unit when the key abnormality is released.

  In addition, by using a capacitive touch panel key configuration with the operation unit key configuration all on the top surface of the main body 1, the touch panel provided on the top surface can be used in the event of inadvertent key input and safety is improved. In addition, a stylish appearance design for the kitchen can be realized or improved.

  In addition, when a foreign object comes into contact with the capacitive touch panel key due to a heated object such as a pan or small metal, the heating operation is continued or stopped by distinguishing the key abnormality detection processing conditions with the input key as described above. By doing, it can be set as the structure which does not stop a heating easily even if to-be-heated is shifted, and cooking property can be improved.

  The electric resistance heating type heating means may have a configuration provided with at least one other than the top surface, for example, a configuration having a roaster used by being incorporated in a kitchen cabinet. In this case, the same key as described above is used. It shall be possible to operate.
