Fig. 1 is an explanatory diagram of an embodiment of the present invention, and Fig. 2 is an explanatory diagram of a conventional example. Device, 12... upper limit temperature setter, 17... first upper limit temperature setter, 18... second
Upper limit temperature setting device.

Claims (1)

[Scope of utility model registration request] a temperature sensor 2 for detecting the internal temperature of the heating tank 1; an upper limit temperature setter 12 for setting a reference temperature for determining that the heating tank 1 is in an abnormal heating state;
A temperature comparator 13 which compares the temperature signals outputted by the temperature sensor 2 and the upper limit temperature setter 12 and outputs a heat generation stop signal for the heating device 4 when the temperature indicated by the former signal becomes larger; 1, in which the upper limit temperature setter 12 is connected to the first upper limit temperature setter 17 for setting the first reference temperature for low temperature cooking, and the first upper limit temperature setter 17 for setting the first reference temperature for low temperature cooking. It consists of a second upper limit temperature setter 18 for setting a second reference temperature for high-temperature cooking higher than the reference temperature, and these first upper limit temperature setters 1
7 or the output of the second upper limit temperature setting device 18 to the temperature comparator 13 which outputs a heat generation stop signal of the heating device 4.
