Even if the operator operates the second operation part, the heating means 14 is not energized, and safety is ensured.

When combined with another safety device, the time may be measured either after turning on the power switch or after the completion of cooking.

If the fixed time is shortened, the convenience becomes worse. Therefore, the setting of the fixed time may be finally set in consideration of safety and convenience.

In the present embodiment, the operating section is described by distinguishing it between the first operating section 16 and the second operating section 18.
As will be understood from the above description, it is not necessary to distinguish them, and it goes without saying that the front first operating portion 16 and the second operating portion 18 may be integrated and provided as an operating portion on the top plate.

(Embodiment 2) A second embodiment of the present invention will be described. This embodiment has the same basic configuration as that of the first embodiment, and the difference is the correspondence of the control means to the input operation. Therefore, the description will be given with reference to FIG.

When a child mischiefs or a small animal depresses the operation key, the operation key is pressed many times, the same key is repeatedly pressed, and the keys of the second operation unit 18a and the second operation unit 18b are pressed. It is illogical rather than logical, such as pressing keys and randomly. Therefore, in the present embodiment, the control unit 21 is provided with a storage unit and a comparison unit, and a plurality of patterns for setting the cooking conditions are stored in advance in the storage unit, and the input signal from the detection unit 20 and the storage unit are stored. The pattern is compared with the generated pattern, and if different, it is determined that the input is an abnormality such as a child's mischief or a small animal's stepping, and the power is turned off.

Similarly, when one operation key is continuously pressed for a predetermined time, it is determined that an abnormality such as a child's mischief or a small animal's step is input, and the power is turned off.

Since the operation of the operation unit is not accepted, it is possible to ensure the same safety as in the first to third embodiments.

The methods described in Examples 1 to 4 may be used alone, but if they can be used in combination, the effects will be further enhanced if they are used in combination.

Further, although the heating cooker has three heating portions in the first to fourth embodiments, the present invention is not limited to this and may be one heating portion as described above. However, there may be four or more locations.

In the first to fourth embodiments, the case where the induction heating means is used in the heating part has been described. However, since the induction heating directly heats the object to be heated, it is visually determined whether or not the top plate is heated. Is not known, that is, because the heating means is not turned on,
The method of the present invention is useful. Therefore, the effect can be obtained by using it in a heating cooker having at least one induction heating means. For the same reason, in the case of a heating cooker having a plurality of heating units, at least one of which is an electric resistance heating type heating unit and the other of which is an induction heating type heating unit, the second operating unit If only the induction heating means is operated, the safety can be secured and the convenience can be improved even if the induction heating means which is frequently used is provided in front of the top plate.

Although the keys of the operating portion on the top plate are of the electrostatic capacitance type, they may have any form as long as they are similar.
