Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric cooker equipped with a temperature control circuit unit that controls the amount of heat generated by a heating element.

BACKGROUND OF THE INVENTION A conventional electric cooker of this type is, for example,
As shown in Publication No. 71, it had a configuration as shown in FIG. In this FIG. 3, 1 is a heating element provided inside the cooking device main body 2, and 3 is a bottom opening of the cooking device main body 2. It is a back plate for closing and is attached to the lower frame 4. Reference numeral 5 denotes a heat shield plate provided between the control circuit unit 6 and the heat generating element 1 in order to thermally insulate the temperature control circuit unit 6 and the heat generating element 3, and this heat shield plate 6 and the back plate 3
It was made up of separate parts.

Problems to be Solved by the Invention However, in the above conventional configuration, the heat shield plate 5 provided between the heating element 1 located inside the cooking device main body 2 and the temperature control circuit unit 6 Since the temperature rises due to the radiant heat received from the heating element 1, there is a problem in that the heat shielding effect between the heating element 1 and the temperature control circuit unit 6 deteriorates.

The present invention is intended to solve the above-mentioned conventional problems, and aims to improve the heat dissipation of a heat shield plate that has become high in temperature, prevent temperature rise as much as possible, and further enhance the heat shielding effect of the heat shield plate. It is something to do.

Means for Solving the Problems In order to solve the above problems, the present invention provides a heat shielding section that thermally insulates a temperature control circuit unit and a heating element provided in the cooking device main body, and It is integrally formed with a back plate portion that closes the bottom opening of the holder.

Function: With this configuration, the heat of the heat shield, which has become high in temperature due to the radiant heat received from the heating element, is transferred to the back plate of the same component facing the outside air at the bottom of the cooker main body, and then A phenomenon occurs in which the heat is dissipated in the back plate, and as a result, the temperature rise in the heat shield part can be prevented as much as possible, so the heat shielding effect of the heat shield part can be further enhanced. It is something.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

In the figure, 11 is the cooking device main body, 12 is a heating element installed inside the cooking device main body 11 via the protective frame 13, 14 is a temperature control circuit unit provided at the bottom of the cooking device main body 11,
Reference numeral 15 denotes a heat insulating back plate attached to a lower frame 16 provided at the bottom of the cooking device main body 11. Part 1
7, and a back plate portion 1 that closes the bottom opening of the cooking device main body 11.
8, and an inclined portion 1 connecting the heat shielding portion 1γ and the back plate portion 18.
9 are integrally formed.

To explain the operation in the above configuration, the heat in the heat shield part 17 of the heat shield back plate 15, which has become high temperature due to the radiant heat received from the heating element 12 through the protective frame 13, is transferred to the outside air at the bottom of the cooking device main body 11. Then, a phenomenon occurs in which the heat is transmitted to the back plate part 18, which is the same component as the heat shield part 17, through the entire slope part 19, and the transferred heat is radiated in the back plate part 18, which is at a low temperature when it comes into contact with the outside air. As a result, it is possible to prevent the temperature rise in the heat shielding part 17 as much as possible.

Effects of the Invention As described above, according to the present invention, there is provided a heat shielding section that thermally insulates the temperature control circuit unit and the heating element inside the cooking device main body;
Since the back plate that closes the bottom opening of the cooker body is integrally formed, the radiant heat received from the heating element at the heat shield is radiated from the back plate that is in contact with the outside air at the bottom of the cooker main body. As a result, an extremely excellent heat shielding effect can be obtained. In addition, the back plate part and the heat shield part't
Since it is composed of one part, the number of parts can be reduced, and as a result, the number of assembly steps and costs can be reduced.
