れているものが一般的であった。Conventional Structure and Problems Conventionally, in this type of heat-sensitive device, the lead wire of the heat-sensitive element 1 is simply formed into a U-shape, and the heat-sensitive element 1 is connected to the heat-sensitive plate 2. It was common for the device to have a hole so that it could be fixed tightly to the surface.

った。However, the normal heat-sensitive element 1 is covered with a thermal insulator such as glass, and if only the heat-sensitive element 1 is in contact with the heat-sensitive plate 2 via the electrical insulator 3, the thermal response is poor.
Despite highly accurate temperature control, there are problems in that the temperature of the controlled object is unstable, causing temperature 1i 11 tuples, warping, and the control temperature changing in response to changes in the outside temperature.

に向上させるものである。Structure of the Invention The heat-sensitive device of the present invention has a heat-sensitive plate and a heat-sensitive element whose lead edge is shaped into a '6s shape. By closely fixing the heat-sensitive element to the heat-sensitive element, the thermal responsiveness of the heat-sensitive element is dramatically improved.

る。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 2 is a cross-sectional view of a pressure cooker having a heat-sensitive device according to the practice of the present invention, where 4 is a heat-sensitive device, 6 is a pot,
6 is a temperature control circuit for heating the pot 5. A heater 17 is a temperature control circuit for controlling the temperature of the pot 5 by also controlling the heating power of the heater 6 using an electric signal from the heat sensitive device 4. 3 and 4 are a cross-sectional view and a plan view of the heat-sensitive device 4. FIG. 8 is a heat-sensitive element; 9 is a heat-sensitive element 8 shaped into an S-shape;
10 is a heat-sensitive plate that contacts the pot 6 and absorbs heat; 11 is an insulation plate for electrically insulating the lead wire 9 from the heat-sensitive plate 10; 12 is a heat-sensitive element 8 and the lead wire 9; Insulating board 1
1 is a rubber fixing plate that is closely fixed to the heat-sensitive plate 10 through 1, an inner case for storing the heat-sensitive element 8 and the fixing plate 12; 14 is the heat-sensitive plate 10 together with the inner case;
An inner case 111 is caulked to block heat from the outside, 15 is a spring for closely contacting the heat-sensitive device 4 to the pot, and 16 is an outer case for fixing the spring 16.
