Description

[Detailed Description of the Invention] The present invention relates to a mounting device for an operation block of a heat insulator and a rice cooker.

Conventionally, the operation cover of a cooking appliance has been molded with resin considering electrical insulation, appearance, and moldability, but in order to attach many parts such as a time switch, indicator lamp, switch, etc. to this operation cover, The operation cover must be large, and if it is molded with resin, it will be weak in strength.

Furthermore, when reinforcing ribs are integrally formed on the operation cover, there are disadvantages in that the space for attaching parts becomes narrow, and deformation caused by the formation of the reinforcing ribs appears on the surface, impairing the aesthetic appearance.

The present invention solves the above-mentioned conventional drawbacks by effectively utilizing the member that pivots the switch lever that starts energizing the heater of the cooker.Please refer to the attached drawings below for examples of the present invention. and explain.

In the figure, 1 is the main body of the cooker, and there is a mounting plate 2 inside.
is fixed.

3 is a heating element provided on the mounting plate 2.

A container 4 is detachably placed on the heating element 3, and a lid 5 is placed on top of the container.

Reference numeral 6 denotes a center thermostat that is activated by sensing a temperature rise at the bottom of the container 4, and the switch lever 7 is rotated by the activation of the center thermostat 6.

8 is an operation cover attached to the main body 1, and an indicator lamp 9, a time switch 10, and a micro switch 11 are mounted on the back side.
is installed.

Further, a through hole 8a is formed in the lower surface of the operation cover 8.

Reference numeral 12 denotes a metal plate that covers the time switch 10 and the microswitch 11. The upper end of this metal plate 12 is screwed to a boss 13 formed approximately in the center of the operation cover 8, and the lower end is attached to the lower end of the operation cover 8. Locking piece 8 formed to protrude
It extends to b and is secured with screws.

The width of this metal plate 12 is provided close to the inside of the side wall surface of the operation cover 8 to prevent the operation cover 8 from being deformed in the lateral direction.

The switch lever 7 is pivotally supported by a protrusion 14 formed by cutting and raising this metal plate 12, and the end opposite to the side connected to the center thermostat 6 passes through a through hole 15 formed approximately in the center of the operation cover 8. ing.

A bent piece 16 is formed at the lower end of the metal plate 12, and a microswitch 17 is fixed to this bent piece 16.

This microswitch 17 opens and closes its contacts by rotating the switch lever 7, thereby controlling the supply of electricity to the heating element 3.

In the above configuration, the switch lever 7 is supported pivotably on the metal plate 12, and the microswitch 17, which opens and closes the contacts by rotation of the switch lever 7, is fixed, so that misalignment between the switch lever 7 and the microswitch 17 is prevented. The operation of the switch lever 7 is accurately transmitted to the microswitch 17.

Further, since the metal plate 12 is located between the electric parts such as the time switch 10 and the microswitch 11 and the heat generating element 3, it can block the heat of the heat generating element 3 and prevent thermal deterioration of the electric parts.

Furthermore, the lower end of the metal plate 12 is attached to the locking piece 8 of the operation cover 8.
b, the force applied when operating the switch lever 7 is transmitted to the main body 1 via the metal plate 12,
There is no need to deform the operation cover 8.

In addition, since the through hole 8a is formed on the lower surface of the operation cover 8, the air near the time switch 10 and microswitch 11 located between the operation cover 8 and the metal plate 12 rises.
It is cooled by the outside air flowing in through the through hole 8a.

As is clear from the above explanation, according to the present invention, the metal plate that covers the electrical components has four functions: supporting the switch lever, fixing the switch, insulating the switch, and reinforcing the operation cover. This results in improved assembly workability and serviceability.
