Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot plate having a detachable plate and controlling the temperature of the plate with a thermostat via a heat receiving plate.

2. Description of the Related Art Conventionally, this type of cooker has a structure as disclosed in Japanese Utility Model Laid-Open No. 57-121228, for example. That is, as shown in FIGS. 5 and 6, a plate 2 as a cooking device main body is mounted on the heating device main body 1, and a heat shield plate 3 is mounted inside the heating device main body 1. A heating element 4 is fixed on the upper surface of the heat shield plate 3, and a hole 5 is provided in a central portion of the heating element 4, and a heat sensing portion 8 of a thermostat 7 that contacts the lower heating surface 6 of the plate 2 through the hole 5. Projecting upward.

The thermostat 7 is connected to a special screw via a concave mounting plate 9 having a spring property and fixed below the heat shield plate 3.
Installed using 10.

In such a conventional configuration, the slidability of the heat-sensitive part 8 is determined only by the spring property of the mounting plate 9, and the heat-sensitive part 8 is not configured to be able to slide up and down sufficiently. In addition, due to lack of stability, the heating surface 6 of the plate 2 pushes the heat-sensitive portion 8 too much due to dimensional variations, and conversely, the heat-sensing portion 8 floats so that the sense cannot be properly received.

Also, the mounting plate 9 for mounting the thermostat 7 has a complicated shape with a concave cross section, and the mounting hole position is shifted due to variation in bending dimensions, and the thermostat 7 may be mounted in a tilted state. For this reason, the heat-sensitive portion 8 is also inclined, and the state of close contact with the heating surface 6 of the plate 2 is deteriorated, so that there is a problem that the sensor cannot be sensed well. In addition, a special screw 10 must be used for attaching the thermostat 7 or a detent must be supported during tightening, and there is a problem in cost and assembly.

SUMMARY OF THE INVENTION The present invention solves such a problem, and provides a cooker that can easily attach a thermostat, and can simultaneously prevent rotation of the thermostat and correct when the heat receiving plate is inclined. It is intended to do so.

Means for Solving the Problems In order to solve this problem, the present invention provides a main body equipped with a heater, a plate detachable from the main body, a hollow substantially cylindrical shape, an axis at a bottom surface at a plate temperature, and A cap provided with a heat receiving plate for receiving heat, a thermostat and a thermo mounting bracket having an L-shaped cross section in the cap,
The thermo mounting bracket has a configuration in which both side portions of one L-shaped piece of the thermo mounting bracket are in contact with the inner surface of the cap.

Operation With this configuration, the holes of the thermostat and the thermo mounting bracket are fitted to the shaft provided at the center of the heat receiving plate, and the nut is tightened with the nut. At this time, even if a force in the rotation direction is applied to the thermomount, the thermostat and the thermomount do not rotate and the nut is tightened because both sides of the thermomount are in contact with the side surfaces of the cap. Also, since the dimensions of the thermo-mounting hole of the thermo-mounting bracket and the both ends in contact with the inner surface of the cap are fixed, even if the heat-receiving plate is tilted and mounted on the cap and the axis of the heat-receiving plate is tilted, the nut is thermo-mounted. By tightening the bracket to a regular position where the L-shaped cross section of the bracket is perpendicular to the bottom surface of the cap, the inclination of the heat receiving plate is corrected, and an excellent close contact between the plate surface and the heat receiving plate can be obtained.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 to 4, reference numeral 11 denotes a cooking device main body, 12 denotes a plate detachable from the cooking device main body 11, and 13 denotes a cap and a spring.
It is attached to the main body 11 so as to be able to slide up and down via 14.
A heat receiving plate 15 which is in contact with the plate 12 and receives the temperature of the plate 12 is attached to the cap 13 by caulking.
The shaft 16 is provided at the center of the lower surface of the. A thermostat 17 is fitted to the shaft 16, a thermo-mounting bracket 18 having an L-shaped cross section is fitted under the thermostat 17, and the nuts 18 and 19 are fastened with a nut 19. A heater 20 is fixed to a heat shield plate 22 inside the cooker main body 11 by a heater support bracket 21. Specifically, the L-shaped thermo-mounting bracket 18 has a thermo-mounting hole 23 in one piece as shown in FIG.
Nut through shaft 16 with thermostat 17
Tightened at 19. At the time of this tightening, as shown in FIG. 2 and FIG.
Is in contact with the inner side surface of the cap 13, the rotation is regulated even if a force for rotating in the direction A is applied to the thermo mounting bracket 18, and positioning can be easily performed. Further, as shown in FIG. 3, the dimension B between the thermo-mounting hole 23 of the thermo-mounting bracket 18 and the side portion in contact with the side surface of the cap 13 is constant.
Although the nut 19 is inclined and attached to the cap 13, as shown in FIG.
The inclination of the heat receiving plate 15 can be corrected by tightening the heat receiving plate 15 to a regular position where it is perpendicular to the bottom surface of the cap 13. For this reason, it is possible to always obtain an excellent state of close contact between the heat receiving plate 15 and the plate 12, thereby exhibiting excellent effects in both performance and assemblability.

Effects of the Invention As is clear from the above embodiment, the cooking device of the present invention
A main body equipped with a heater, a plate detachable from the main body, a cap having a hollow substantially cylindrical shape having a shaft at the bottom surface, and a heat receiving plate for receiving the plate temperature, a thermostat fitted to the shaft, and It consists of a thermo-mounting bracket with an L-shaped cross-section, and both sides of one piece of the L-shaped thermo-mounting bracket are in contact with the inner surface of the cap. Even if a force in the rotating direction is applied, the thermostat and the thermostat are restricted from rotating because both sides of the thermostat are in contact with the inner surface of the cap, and the thermostat can be easily mounted on the cap. Also, since the dimensions of the thermo-mounting hole of the thermo-mounting bracket and the both ends in contact with the side of the cap are fixed, even if the heat-receiving plate is tilted and attached to the cap and the axis of the heat-receiving plate is tilted, the nut is attached to the thermo-mounting bracket. By tightening to the regular position where the L-shaped cross section is perpendicular to the bottom surface of the cap, the inclination of the heat receiving plate is corrected, and excellent close contact between the plate surface and the heat receiving plate can be obtained. A great effect can be obtained.
