Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hot plate type cooking device for general household use.

BACKGROUND OF THE INVENTION A conventional cooking device of this type is disclosed in Japanese Patent Application Laid-Open No. 6O-2386, for example.
As shown in Publication No. 1J3, the structure was as shown in FIGS. 3 and 4. In other words, the heating element 1 is placed on the back side.
A cooking device main body 2 having a terminal bar 3 protruding from the heating element 1, a connecting pin 6 fixed to the insulating plate 4 and connected to a power source, one end of which is clamped and fixed to the connecting pin 6,
and a lead plate 6 whose other end is connected to the terminal bar 3; a support fitting 7 made of a sheet metal that is clamped and fixed to the insulating plate 4 and fastened to the cooking device main body 2; and a support fitting 7 fixed to the support fitting 7. The heating element 1 was constructed of an insertion frame 8 and a heat shield plate 9 covering the lower part of the heating element 1.

Problems to be Solved by the Invention In conventional cookers, the insertion frame 8 is fixed to the cooker main body 2 via the support fitting 7 made of sheet metal, so the fixing force is unstable, and therefore the difference When an external force is applied to the insertion frame 8, a positional shift occurs.Furthermore, on the processing side, after caulking the support fitting 7 to the insulating plate 4 and fastening the support fitting 7 to the cooker main body 2, the insertion frame 8 is attached to the support fitting. Since it is fixed to the child, there is a problem that the processing procedure becomes complicated.

An object of the present invention is to provide a cooking appliance that solves these problems.

Means for Solving the Problems In order to solve the above problems, the cooking device of the present invention comprises a cooking device main body having a heating element at the bottom, a terminal bar protruding from the heating element, and attached to an insulating plate, and a connecting pin connected to a power source, and a lead plate fixed to the connecting pin and connected to the terminal bar, the insulating plate and an insertion frame covering the connecting pin being integrally formed. .

Further, the connecting pin is clamped and fixed to a resin insulating plate via an elastic body, and then the lead plate is clamped and fixed to the connecting pin.

Function The cooker configured as described above has the insulating plate and the insertion frame that covers the connection pins integrally formed, so by fixing the insertion frame to the cooker body, the insulating plate can be removed. It is rigidly fixed, which means that even if the consumer applies external force to the insertion frame during use, the insulating plate will not easily shift or deform, and the live part will be reliably protected, making it safe. can provide something.

In addition, since the connecting pin is clamped and fixed to the resin insulating plate via an elastic body, the lead plate is clamped and fixed to the connecting pin, so even if the resin insulating plate shrinks in size during long-term use. There is no rattling, and since the connection between the lead plate and the connection pin is caulked between metals, reliable electrical conduction is possible.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. FIG. 1 shows one embodiment of the present invention.
In the figure, reference numeral 11 denotes a cooking device body having a heating element 12 at the bottom, from which a terminal bar 13 protrudes. Reference numeral 14 denotes an insulating plate made of synthetic resin. A connecting pin 16 connected to a power source is clamped and fixed on this insulating plate 14, and the other end of the lead plate 16, whose one end is connected to the terminal bar 13, is connected to the connecting pin. It is clamped and fixed to 16. Reference numeral 17 denotes an insertion frame that covers the connecting pin 15, and this insertion frame 17 is formed integrally with the insulating plate 14.

Since the insertion frame 17 is formed integrally with the insulating plate 14 in this way, by fixing the insertion frame 17 to the cooking device main body 11, the insulating plate 14, which clamps and fixes the connecting pin 16, also becomes a rigid body. As a result, even if a consumer applies an external force to the insertion frame 17 during use, it will not be displaced or deformed, so that the live part is safely protected.

Further, the connecting pin 16 is connected to the insulating plate 14 via the elastic body 18:
After clamping and fixing, the lead plate 16 is clamped and fixed to the connecting pin 16, so even if the synthetic resin insulating plate 14 shrinks in size due to heat cycles during long-term use, the shrinkage elastic body 18 Since the lead plate 16 and the connecting pin 16 are directly caulked together in the energizing part, the reliability of energization can be ensured.

Then, attach the insertion frame 17 with screws 2 to the heat shield plate 19 attached to the cooking device main body 11 so as to cover the lower part of the heating element 11.
By fastening with o, the insertion frame 17 is attached to the cooking device main body 11.
Since it is possible to fix the insertion frame 17 to the cooking device main body 11 during assembly, there is no need to separately fix the insertion frame 17 to the cooking device main body 11, thereby saving labor in assembly.

FIG. 2 shows another embodiment of the present invention.
In the illustrated embodiment, the insulating plate 14 is made of ceramic, and the insulating plate 14 is insert-molded into an insertion frame 17 made of resin. With this configuration, the lead plate 16
The part where the connecting bottle 15 is clamped and fixed will not change over time even when used at high temperatures, making it safe, and as a result,
This increases reliability.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
Since the insulating plate and the insertion frame that covers the connection bottle are integrally formed, by fixing the insertion frame to the cooker body, the insulating plate to which the lead of the heating element is fixed can also be rigidly fixed. As a result, even if a consumer applies an external force to the insertion frame during use, it will not be displaced or deformed, so the live part can be safely protected.

In addition, after the connecting pin is clamped and fixed to the resin insulating plate via an elastic body, the lead plate is clamped and fixed to the connecting pin, so even if the resin insulating plate shrinks in size during long-term use, the elastic It can be absorbed by the body, so there is no rattling, and since the connection between the lead plate and the connecting pin is directly caulked metal,
This enables reliable energization and ensures reliability of energization.
