品点数が倍増し、コスト高になる難点がある。<Prior art> The most well-known conventional temperature detection device of this type is the center thermo method, which detects the presence or absence of an object to be heated such as a pan, and connects the heater power supply circuit to the machine. It was configured to open and close using a manual switch, and was not configured to continuously detect the temperature of the heated object and perform temperature control.
As a conventional technology capable of temperature control, there is also a known technology that detects the presence or absence of an object to be heated at the bottom of the pan, and also detects the temperature on the side of the pan to control the temperature. Since there are two detection points, one for detecting the heated object and the other for temperature detection, there is a problem that the number of parts is doubled and the cost is increased.
