Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for a cooker such as a rice cooker that is used at home and has a display unit.

2. Description of the Related Art A conventional display device for this type of cooking device has a structure as shown in FIG. That is, 101 is a display device 1 for display.
A display board in which a circuit board 103 having 02 and an electronic component is fixed with screws 104. Reference numeral 105 denotes a film-like display sheet attached with a double-sided adhesive tape so as to cover the opening of the display plate 101, and a decorative plate 106 is attached to the inner surface of the display sheet 105. 107 is a silicone rubber indicator packing, and this indicator packing 107 holds the indicator 102 with an L-shaped claw 108 and brings the tip 109 into contact with the decorative plate 106 to form the decorative plate 106. A space between the display devices 102 is formed to have a static air layer to prevent dust and steam from entering between the decorative plate 106 and the display devices 102.

Problems to be Solved by the Invention In such a conventional configuration, the display packing 107 is attached to the display 102, and the circuit board 103 is fastened to the display plate 101 with the screw 104. For efficiency, tighten the screws 10 vertically from top to bottom.
Contrary to the tightening direction of 4, the indicator packing 107 caught on the indicator 102 is made of rubber, so that it is easy to come off, and as a result, the tip 109 of the indicator packing 107 has a decorative plate 10.
There was a problem that 6 could not be properly adhered and a sealed state could not be formed.

Further, since the L-shaped claw 108 of the display plate packing 107 is undercut, there is a problem that it takes a lot of man-hours for the releasing work after the molding.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a display device of a cooker which has excellent assembling workability, can reliably form a sealed state, and has good workability of a display plate packing. To do.

Means for Solving the Problems In order to solve the above problems, the present invention provides a display board in which a circuit board having a display is fixedly secured by screws and housed, and a decorative board equipped in an opening portion of the display board. And an annular indicator packing that is interposed between the decorative plate and the indicator and has a static air layer between them, and the indicator packing extends a part of its outer peripheral portion. To form a claw on the flat surface and the tip of the inner peripheral portion is formed to project from the flat surface.
The decorative plate or the display plate is provided with a convex portion with which the claw engages, the claw and the convex portion are engaged with each other, and the tip of the inner peripheral portion of the indicator packing is brought into contact with the display device over the entire circumference. The packing is fixed to a decorative board or a display board.

In addition, the indicator packing has a hole formed in the outer peripheral portion thereof and a protruding end portion of the inner peripheral portion, and the decorative plate or the display plate is provided with a convex portion to be inserted into the hole, and the convex portion is inserted into the hole. The display packing is fixed to the decorative plate or the display plate by abutting the tip of the inner peripheral portion of the display packing on the display over the entire circumference.

Operation According to the above configuration, when the circuit board having the display is fastened to the display board with the screw, the display packing is fixed to the decorative board or the display board in the gravity direction, and the decorative board or the display board is Since it is in the stationary state, the indicator packing does not fall off or shift, and the indicator and the display plate packing can be accurately brought into contact with each other.

Also, since the indicator packing is not fixed in the direction opposite to gravity, it is not necessary to have an undercut shape, resulting in excellent assembly workability, stable quality, and cost reduction. It will be.
