Abstract

PURPOSE:To prevent the generation of rattling of an insertion frame for an external force by fixing the insertion frame onto a cooker body through a rigid insulating plate. CONSTITUTION:An insulating plate 14 is held by a holding part 19 projecting from one part of a cooker body 12, and an insertion frame 18 is fixed onto a heat shielding plate 17 by a machine screw 20 through the insulating plate 14, and the insertion frame 18 can be surely fixed onto the cooker body 12 by the rigid insulating plate 14. Therefore, even if an external force is applied onto the insertion frame 18 during use, the deflection of position and generation of deformation are prevented, and since an electric charge part can be safely protected, the accident such as electric shock can be prevented.

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.

2. Description of the Related Art A conventional cooking device of this type is disclosed in Japanese Patent Application Laid-Open No. 60-2366, for example.
As shown in Publication No. 18, the structure was as shown in Figures 3 and 4. That is, a cooking device main body 2 having a heating element 1 on the back side, a terminal bar 3 protruding from the heating element 1, a connecting pin 6 fixed to an insulating plate 4 and connected to a power source, and a connecting pin 6 connected to the connecting pin 6. a lead plate 6 whose one end is clamped and fixed and whose other end is connected to the terminal bar 3; a support fitting 7 made of a sheet metal which is clamped and fixed to the insulating plate 4 and fastened to the cooking device main body 2; It consisted of an insertion frame 8 fixed to the support fitting 7 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, in the machining process, after caulking the support fitting 7 to the insulating plate 4 and fastening the support fitting A to the cooker main body 2, the insertion frame 8 is attached to the support fitting. 7, there was a problem that the processing procedure became 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 includes a cooking device main body having a heating element at the bottom, a terminal bar protruding from the heating element, fixed to an insulating plate, and a power supply. a lead plate that is clamped and fixed at one end to the connection bin and connected to the terminal bar at the other end, and a shield attached to the cooker body so as to cover the lower part of the heating element. It has a heating plate and an insertion frame attached to the lower outer peripheral surface of the cooking device main body so as to cover the insulating plate and the connection bottle, and the insertion frame is attached to the cooking device main body through the insulating plate which is a rigid body. It is designed to be fixed.

Function In the cooking device configured as described above, the insertion frame is fixed to the cooking device main body via the rigid insulating plate, so the insertion frame can be securely fixed, and as a result, it is resistant to external forces. On the other hand, the insertion frame does not easily rattle.

Furthermore, since the insulating plate is attached directly to the cooking device main body, processing is simplified and reliable.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the accompanying drawings. In FIGS. 1 and 2, reference numeral 11 denotes a cooking device main body having a heating element 12 at the bottom, from which a terminal bar 13 protrudes.

14Vi insulating plate, a connecting pin 15 connected to a power source is clamped and fixed on this insulating plate 14, and the other end of a lead plate 16, one end of which is connected to the terminal bar 13, is connected to the connecting pin 1.
5 is a heat shield plate 1 attached to the cooking device main body 12 so as to cover the lower part of the heating element 11;
Reference numeral 8 denotes an insertion frame that is attached to the lower outer peripheral surface of the cooking device main body 12 so as to cover the insulating plate 14 and the connecting pin 15. The insulating plate 14 is held by a holding part 19 that protrudes from a part of the cooking device main body 12, and the insertion frame 18 is fixed to the heat shield plate 17 with screws 20 via the insulating plate 14, so that the difference can be increased. The mounting frame 18 is securely fixed to the cooking device main body 12 by an insulating plate 14 which is a rigid body. This results in
Even if an external force is applied to the insertion frame 18 during use by a consumer, the insertion frame 18 will not be displaced or deformed, and the charging portion will be reliably protected, thereby preventing accidents such as electric shock.

Furthermore, by composing the insulating plate 14 with ceramic, the electrical insulation performance is improved especially when used at high temperatures, and the mechanical strength is also increased, making it possible to provide consumers with a safe and reliable cooker. can.

Further, as shown in FIG. 1, the insertion frame 18 is fixed to the cooking device main body 12 by fastening the insertion frame 18 to the heat shield plate 17 fixed to the cooking device main body 12 with screws 20. Therefore, the insulating plate 14, which has a sandwich structure between the cooking device main body 12 and the insertion frame 18, can also be fixed at the same time, and as a result, the insulating plate 14 can be independently fixed to the cooking device main body 12 during assembly. Since there is no need to do this, assembly labor can be saved.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
Since the insertion frame is fixed to the cooking device main body via a rigid insulating plate, the insertion frame is rigidly fixed to the cooking device main body, and as a result, the external force during use by the consumer is reduced. If the insertion frame becomes misaligned or deformed, it can reliably protect the live part.

Furthermore, since the insulating plate is made of ceramic, it is possible to improve the electrical insulation performance during high-temperature use, and the mechanical strength is increased, making it possible to provide a safer and higher quality cooker. Furthermore, by fixing the insertion frame to the heat shield plate fixed to the cooking device main body, the insulating plate is also fixed at the same time, which saves labor during assembly.
