JPS5836340Y2 - Thermostat fixing device for electric cooker - Google Patents

Description

[Detailed explanation of the invention] This invention originally consisted of several pillars erected on a hot plate for fixing the bottom cover with bolts, and a thermo fixing plate for fixing the thermostat and the bottom cover. This invention relates to a thermostat fixing device for an electric cooker that also serves as a mounting device.

Conventionally, in various electric cooking appliances such as rice cookers, deep fryers, and water boilers, a sheathed heater or the like is fixed to a hot plate placed at the bottom of the cooking appliance body using appropriate fixing means such as caulking, and the heating plate is heated. A thermostat that detects the temperature and regulates the energization of the heater to make it possible to adjust the heating temperature is fixed to appropriate locations on the hot plate using bolts, etc., and is further attached to multiple pillars welded to the hot plate. Some devices have a structure in which internal heating members such as the heater and thermostat are covered by fixing the bottom cover with bolts.

By the way, this conventional product requires work in a narrow space to attach the thermostat to the hot plate, making it difficult to assemble, and it also takes time and effort to form bolt holes for attaching the thermostat to the hot plate. It took a long time and required mounting parts such as bolts.

The present invention was developed in view of the above points, and its original purpose was to simply and easily fix the thermostat by fixing the thermostat plate to the pedestal that is welded to the hot plate for attaching the bottom cover. The purpose is to securely fix the heat plate to the lower surface of the hot plate, thereby improving the efficiency of the mounting work and reducing the number of parts.

Hereinafter, details of the present invention will be explained with reference to an embodiment shown in the drawings.

Reference numeral 1 denotes a cooking device main body, 2 a heating plate disposed at the bottom of the cooking device main body 1, and a heater 3 such as a sheathed heater is fixed to the heating plate 2 as appropriate, for example, as shown in the figure, on the outer bottom surface of the heating plate 2. It is fixed in the recessed part 4 formed by crimping or welding (not shown).

Reference numeral 5 denotes a plurality of pillars erected on the outer bottom surface of the hot plate 2.

Reference numeral 6 denotes a thermo fixing plate, and a plurality of cut-outs 9 are formed on the upper step 7 of the thermo fixing plate 6 for caulking and fixing the lower part of the base 8a of the thermostat 8.

The thermostatic fixing plate 6 is fixed to the pillars 5, 5 by middle bolts 10.

Reference numeral 11 denotes a bottom cover that covers the lower part of the hot plate 2;
Bolt insertion holes 12, 12 into which the above-mentioned middle seat pole 10 and 10 are inserted are bored in 1.

Moreover, the bottom cover 11 is attached to the middle bolt 10 and the nut 1 at 10.
It is fixed by screwing 3 together.

Since one embodiment of the present invention has the above-described configuration, in order to bring the thermostat 8 into close contact with the outer bottom surface of the heating plate 2, the notch 9 of the thermofixing plate 6 must first be bent. The lower part of the base 8a of the thermostat 8 is crimped and fixed to the thermo fixing plate 6 by the following steps.

Thereafter, as described above, the thermo fixing plate 6 with the thermostat 8 crimped and fixed is attached to the center bolts 10 of the plurality of (two in the drawing) pillars 5.5 welded to the outer bottom surface of the hot plate 2. ．．
Fix at To.

At this time, the upper surface of the base 8a of the thermostat 8 is in contact with the hot plate 2, and the other side, the lower part of the base 8a, is in contact with the thermo fixing plate 6. The thermostat 8 can be held in close contact with the outer bottom surface of the hot plate 2 with certainty.

As mentioned above, the present invention originally allows the thermostat to be easily and reliably fixed to the bottom surface of the hot plate by simply fixing the thermo fixing plate to the pillars welded to the outer bottom surface of the hot plate in order to attach the bottom cover. As a result, it is possible to improve the efficiency of the installation work of the thermostat fixing plate I compared to conventional products of this type.Moreover, it is not necessary to form bolt holes etc. in the hot plate for attaching the thermostat, making it easier to manufacture. By using the same center bolt as both the bolt for fixing the bottom cover and the bolt for fixing the thermo fixing plate, there are effects such as a significant reduction in the number of parts.
