Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric cooker such as a rice cooker and heat insulator.

Conventional structure and its problems Conventionally, in this type of electric cooker, the caulking metal fittings and the sensor were fixed at different positions with respect to the circumferential direction of the cylindrical outer pot. It was common.

However, with this configuration, the caulking metal fittings that fix the side heater and the sensor mounting base that fixes the sensor must be fixed to the outer pot with separate fastening parts, which makes workability difficult and reduces the number of parts. In addition to the increased cost and the high cost, there is a tendency for differences in the spacing between the side heater and the sensor in the height direction of the outer pot, resulting in poor detection accuracy and difficulty in stable temperature control. There was a problem.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides an electric cooker that improves workability and performance and reduces costs.

Structure of the Invention The electric cooker of the present invention includes: a cylindrical inner pot with a bottom; an outer pot having a gap with respect to the inner pot; and a sensor that contacts the inner pot and controls the internal temperature of the inner pot. a sensor mounting base made of a thermally insulating material for fixing the sensor; a p-side heater for heating wrapped around the outer periphery of the outer pot; a caulking fitting for fixing the side heater; the outer pot and the sensor; - It consists of a mounting base and a fastening part that fixes the caulking fitting.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In Figures 1 to 3, 1 is an outer pot, 2 is a side heater for heating wrapped around the outer periphery of the outer pot 1, and 3 is a caulking metal fitting for fixing the side heater 2. It is provided on the outer periphery of 1. Reference numeral 4 denotes a sensor mounting base made of a thermally insulating material, and is fixed to the outer circumference of the outer pot 1 by a fastening part 5 in a state where it is sandwiched between caulking metal fittings 3. 6 is a sensor for temperature control, which is detachable from the sensor mounting base 4. 7 is a sensor lead wire, which is fixed by the sensor mounting base 4. Reference numeral 8 denotes an inner pot which has a gap on the inner surface of the outer pot 1 and is detachably provided.

To explain how to attach the above configuration, first, the sensor 6 is attached and fixed to the sensor mount 4. Next, the sensor lead wire 7 is fixed to the sensor mounting base 4.

Next, remove the sensor mounting base 4 with the sensor 6 installed.
Temporarily fix with caulking metal fitting 3. The temporarily fixed sensor mounting base 4 and caulking metal fitting 3 are fixed to the outer periphery of the outer pot 1 through a hole provided in the outer pot 1 using a fastening part 5. Finally, the side heater 2 is wrapped around the outer periphery of the outer pot 1, and the side heater 2 is fixed with a caulking metal fitting 3.

Since the sensor mounting base and the side heater 2 are fixed with the caulking metal fittings 3 in this way, the installation work can be streamlined, and the distance between the side heater 2 and the sensor 6 can be kept constant, increasing the detection accuracy of the sensor 6. . Furthermore, since the sensor mounting base 4 is made of a thermally insulating material, the heat from the side heater 2 is not directly transmitted to the sensor 6, so that detection accuracy can be further improved.

Effects of the Invention As is clear from the above embodiments, the electric cooker of the present invention includes a thermally insulating sensor mounting base equipped with a sensor,
By thermally insulating the caulking metal fittings that fix the side heater, fixing it with a common fastening part while maintaining its performance as a temperature control element, and fixing the main/side +7- lead wires to the sensor mounting base. , the number of parts is reduced, and as a result, workability can be improved and costs can be reduced.

In addition, since the sensor mounting base and the caulking metal fittings are fixed at the same location, the distance between the side heater and the sensor is extremely stable, and is not easily affected by the temperature distribution in the height direction of the outer pot. The thermal relationship with the inner pot is always constant, and the temperature inside the inner pot can be controlled very accurately.
