The water level display window 17 is provided at one side of the outer surface of the main body 10, and the water level of the heat medium in the accommodation space 11 can be confirmed through the water level display window 17.

The heating unit 20 includes a heating body 21 that is heated by electric energy to heat the heating medium, and a heat transfer member 22 that transfers the heat of the heating body 21 to the heating medium side.

The heating body 21 has a structure such as a heating coil, and the heating body 21 is electrically connected to the control unit 30 side.

The heat transfer body 22 is a thermally conductive material and covers the outer surface of the heating body 21 and is sealingly coupled to the coupling hole 11b of the bottom surface 11a. Looking at this in more detail, the annular protruding edge 22a protrudes in the outer diameter direction on the lower surface of the heat transfer body 22, the packing 23 is installed in the coupling hole 11b, and the protruding edge 22a is the packing 23. The heat transfer body 22 is hermetically coupled to the coupling hole 11b by being disposed above. The lower surface of the heat transfer body 22 is coupled to the lower side of the bottom surface 11a through a fixing bracket 24, and the fixing bracket 24 is coupled through the fasteners 24a and 24b.

By this structure, the heat heated by the heating body 21 of the heating part 20 is transmitted through the heat transfer body 22, and in the receiving space 11 by the heat transmitted through this heat transfer body 22. The heat medium is evaporated, and the vaporized steam passes through the through hole 12a of the support plate 12 to steam and cook the food in the food container 13.

The thermal insulation temperature switch 25 may be a bimetal thermostat electrically connected to the heating element 21 and the control unit 30, and the thermal insulation temperature switch 25 may be a heating element 22 or a receiving space 11. When the heat medium of) reaches the set warming temperature, the electrical contact is turned off to cut off the power to the heating element 21 side. Then, when the heat medium falls below the set warming temperature, the warming-on switch 25 has its electrical contact turned on, and power is supplied to the heating element 21 side.

Here, the heat retention temperature is set to a specific temperature below the break point of the heat medium, for example, a temperature of 95 ° C. (for example, when water having a break point of 100 ° C. is a heat medium), and the heat medium is evaporated by the heat retention temperature switch 25.
