Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to some embodiments of control components in cooking appliances such as jar rice cookers.

Structure of the conventional example and its problems A conventional cooker, for example, a jar rice cooker, has a display box 2 attached to the side of the main body 1 as shown in FIG. 1, and a control part 3 is housed in the display box 2. . Note that 4 indicates a switch lever. The size of this display box 2 is limited due to reasons such as appearance, and it is impossible to accommodate a control device that controls the current of an electric heating element using a semiconductor display.

FIG. 2 shows another conventional example, in which double bottom plates 6 and 9 are fixed to the bottom of the main body 5, and control parts 7 and 8 are placed in the space formed between the double bottom plates 6 and 9. It is stored. However, in this case, despite the small capacity of the heating element,
There was a drawback that the distance a between the heating element and the bottom plate 6 had to be increased, resulting in an increase in overall size.

OBJECTS OF THE INVENTION The present invention was devised in view of the above-mentioned drawbacks of the prior art, and an object of the present invention is to improve reliability by providing heat countermeasures to control components and preventing water droplets from entering.

Structure of the Invention In order to achieve the above object, the present invention provides an opening at the bottom of a main body housing a heating element and a pot heated by the heating element, and a plate-shaped heat shield plate projecting upward to cover the opening. A bottom plate is fixed to the lower surface of this heat shield, a control component is housed in the space formed between this bottom plate and the heat shield, and this control component is screwed into the stepped part of the heat shield that protrudes above the heat shield. Holes are provided to secure the control components, and a heat shield plate provides heat insulation and waterproof effects.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 3, 11 is a control electronic circuit, and 13 is a power control element unit. Reference numeral 12 denotes a heat shield plate attached to the opening at the bottom of the main body, and is shaped like a plate and projects upward. 16 is a bottom plate fixed to the lower surface of the heat shield plate 12;
A space is formed between the heat shield plate 6 and the heat shield plate 12, and a control electronic circuit 11 and a power control element unit 13 are housed in this space. Reference numeral 17 denotes a step-processed part that protrudes in all directions of the heat shield plate 12, and screw holes are provided so that the control electronic circuit 11 is fixed with screws 19. Reference numeral 14 denotes a bottom plate abutting protrusion formed on the heat shield plate 12, and this protrusion 14 allows the heat shield plate 12 to
and the bottom plate 16 partially contact each other, and the inflow of outside air,
It allows leakage. 15 is a leg.

Effects of the Invention As is clear from the above configuration, according to the present invention, control components such as a control electronic circuit and a power control element unit can be stored compactly, and the assembly is easy, and the heat from the heating element above can be dissipated. It can be shielded by a heat shield plate, lowering the temperature of the parts and improving reliability. Even if water accidentally drips from above, only the mounting chair hole for the control parts is higher than the surrounding area, so water will not get in and the parts will not deteriorate.
Its value is great.
