Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a switch device for a cooking appliance that has a control circuit inside a display board and has internal wiring.

BACKGROUND TECHNOLOGY Conventionally, a switch device for this type of cooker has a fourth
The configuration was as shown in the figure. That is, a display board 22 is provided on the outside of the cooking device main body 21, and a circuit board 23 for controlling and displaying the cooking status is fixed on the back side with screws 24. A board cover 25 for insulation is provided between the heat shield plates 26, and a cooking button 27 for performing cooking operations is pivotally supported on the heat shield plate 26 by a shaft 28.

FIG. 5 is a perspective view of a main part, in which a circuit board 23 with lead wires 29 is temporarily fixed to a board cover 25, and a cooking button 27 is pivotally supported on a heat shield plate 26 by a shaft 28.

The heat shield plate 26 uses a metal material such as a pressed part of a steel plate due to strength issues, so when the lead wire 29 is wired in the direction of the arrow 30, the fifth
As shown in Figure A, the lead wire was in contact with the edge portion 26a of the heat shield plate 26.

Problems to be Solved by the Invention As described above, in the conventional configuration, the lead wires 29 were in contact with the edge portion 26a of the heat shield plate 26, so the lead wires were rubbed during wiring work, and the sheathing of the lead wires was torn. I was doing a lot of things. Therefore, as a countermeasure, the fifth
Use rubber bushings 31 as shown in Figure B,
It protected the lead wire.

The present invention takes these problems into consideration and aims to wire the lead wires without using bushings or the like and without damaging the lead wires.

Means for Solving the Problem In order to solve this problem, the present invention provides a display board on the outside of the cooker body, a control section on the inner surface of the display board, and a heat shield on the back of the control section. The heat shielding device is provided with a plate, a cut and raised piece is formed on a part of the heat shield plate, and a lead wire from the control section is bound by coming into contact with the cut and raised piece of the heat shield plate.

Effect: With this configuration, the lead wires do not hit the edges of the heat shield plate, so the sheathing of the lead wires is not damaged.

Examples Examples of the present invention will be described below in Figures 1 to 3.
This will be explained with reference to the figures. In FIG. 3, reference numeral 1 denotes a cooking device main body, which is provided with a heating element 2 inside and a display board 3 on the outside. A control unit 4 is fixed to the inner surface of this display board 3 with control unit fixing screws 5.
The control unit 4 is covered with a heat shield plate 7 with an insulating plate 6 interposed therebetween. Note that the insulating plate 6 is fixed to the display board 3 with fixing screws 8.

A lead wire 9 is fixed to the control section 4,
It is wired in the direction of arrow 10 (backwards). A cut and raised piece 7a is formed on the side line portion of the heat shield plate 7, and a binding hole 7b for attaching a binding band 11 is provided in this cut and raised piece 7a. The lead wires 9 are bound by a binding band 11 attached to the binding hole 7b of the cut and raised piece 7a, and are brought into contact with the surface of the cut and raised piece 7a. Since the cut and raised pieces 7a are bent and have no edges, the lead wires 9 can be wired without being damaged.

Effects of the invention As described above, according to the invention, it is possible to protect the lead wires of the control section of the switch display board device without using protective parts such as bushings, and the operator can also protect the lead wires from damage during assembly. As there is no need to be careful not to damage the lead wires, assembly can be carried out efficiently.In addition, it is easy to tie the lead wires together with the cable ties because the cut and raised strips are on the sides. Since it is attached, it can be easily tied, and it also leads to an improvement in the quality of the cooker. In addition, since the lead wires are tied to the cut and raised pieces, the lead wires may move due to vibration during transportation.
This prevents damage caused by rubbing against the edges of the heat shield.
