Conventional Structure and Problems Conventionally, in this type of rice cooker, as shown in FIG. A heat sensing element 5 was provided in the through hole 3 to protrude and come into contact with the inner pot 4.

Generally, it was fixed to an appropriate position on the bottom surface of the outer pot 2 with screws or the like. Note that 7 is a heat insulating material such as glass fiber. However, with this configuration, when it becomes necessary to replace the heat sensing element 5, it is necessary to turn over the main body 1, remove the screws, remove the mounting base 6, and replace the heat sensing element 6. Because of this, it was often inconvenient to have to turn the heavy main body 1 upside down. However, when keeping rice warm, the heat sensing element 5 has a fixed position in contact with the inner pot 4 based on experience. The length from which the heat sensing element 5 touches the inner pot 4 was varied depending on the rice cooker of each container.

In addition, an electric rice cooker (hereinafter referred to as a jar rice cooker) that also serves as a heat insulator
In this case, since the heat insulating paulownia 7 is provided on the outside of the outer pot 2, the heat insulating material does not come into close contact with the outer pot 2 due to the mounting base 6.
This was disadvantageous for heat retention.

This is because the insulation material 7 is made of glass fiber, and it is well known that the insulation effect improves depending on the amount of air contained in this glass fiber, but the insulation material on the mounting base 6 is thin. This was because the insulation effect would deteriorate.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 to 4, 8 is a negative characteristic thermistor that senses heat, and is insulated and protected by a heat-resistant tube 11 made of fluorocarbon resin or the like. This negative characteristic thermistor 8 is connected to a sensor retainer 9 between the connector 12 and the sensor mounting LJ plate 10.
It is supported on the inner surface side of the connector 12 via. The connector 12 contacts the outer periphery of the inner pot 4 and conducts the heat of the food to be heated, such as rice water, in the inner pot 4 to the negative characteristic thermistor 8. Reference numeral 13 denotes a mounting base for fixing the sensor mounting plate 10 to the outer surface of the outer pot 2, which is made of resin or the like with poor heat conduction to prevent heat conduction from the sensor mounting plate 10 to the outer pot 2. .14
1 is a protrusion provided on the mounting base 13, 15 is a through hole provided on the mounting base 13, and 16 is a through hole provided on the g111 wall of the outer pot 2.
4 is inserted. A through hole 17 is provided in the side wall of the outer pot 2 and communicates with the through hole 16. 18 is the protrusion 1 of the connector 12
It is a through hole into which 9 is fitted, and is provided in the side wall of the outer pot 2. 2
o is a rivet that is inserted into the through holes 17 and 15, and has a cylindrical shape with two steps of large and small diameters, with the tip 22 on the small diameter side and the tip 22 on the small diameter side.
By pushing in the push rod 21, the protrusion 23 provided on the inner surface of the tip 22 allows the four-divided portion to expand outward as shown in FIG. Ru.
