Description

[Detailed Description of the Invention] The present invention relates to a keyboard mounting structure in a cooking appliance.

BACKGROUND ART Recently, microcomputer-equipped cookers have become popular, which combine a heater, steam, high-frequency heating, etc., and are equipped with a microcomputer to store cooking programs in advance and perform automatic cooking. Generally, the method of storing this cooking program is to arrange a touch-type keyboard 1 as shown in FIG.
Cooking programs can be memorized. The keyboard 1 is usually mounted within the frame 2 by screws. However, the conventional mounting structure for the keyboard 1 as shown in FIG. 3 has the drawback that the resin frame 2 warps during molding, impairing its appearance, as shown in FIG. Furthermore, this also has the disadvantage of creating gaps between the frame 2, the keyboard 1, and the nameplate 3 as shown in FIG. Furthermore, keyboard 1
Since it was a touch type, it had drawbacks such as bending when the surface was pressed.

The present invention was made to eliminate the above-mentioned drawbacks, and its purpose is to provide a protruding rib that supports the outer surface of the keyboard on the side surface of the frame, and to provide a rib that supports the outer surface of the keyboard in the center of the side surface of the frame. To provide a keyboard mounting structure for a cooker which can eliminate warping during frame molding, prevent a gap between a name plate and a keyboard, and prevent deflection of the keyboard by installing engaging claws.

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 4, 4 is a frame, and within the frame 4, a keyboard 1 as shown in FIG. 5 is fixedly attached. That is, frame 4
Ribs 5 are provided on both side surfaces of the frame 4 to project into the frame 4, and the distance between the protruding ends of the ribs 5 facing each other is equal to the width of the keyboard 1. The inner width of the frame 4 is wider than the width of the keyboard 1, except for the area between the ribs 5. Frame 4
Nails 6 are provided at the center of both inner sides and are adapted to engage the keyboard 1. The claws 6 are formed so as to hold the sides of the keyboard 1 inserted into the frame 4, as shown in FIG.
To fix the keyboard 1 to the frame 4, the keyboard 1 is inserted into the frame 4 as shown in FIGS. 6 to 8, and then the screws 7 are tightened. The nameplate 3 is fixed by fitting into a groove 8 provided on the surface of the frame 4.

According to this mounting structure, even if the frame 4 is warped during molding, when the keyboard 1 is inserted into the frame 4, the inside of the frame 4 will receive a force in the direction of pushing the keyboard 1 apart through the ribs 5. So, frame 4
The warpage is eliminated. In this case, since the structure is such that the inner surface of the frame 4 other than the ribs 5 does not come into direct contact with the outer surface of the keyboard 1, friction when inserting the keyboard 1 into the frame 4 can be reduced, improving workability. Since the claws 6 are provided at the center of both sides of the frame 4, when the keyboard 1 is inserted into the frame 4, the frame 4 is pushed out by the amount of the claws 6, and then the frame 4 is opened as shown in FIG. , the keyboard 1 is inserted so that the claws 6 embrace the sides of the keyboard 1. Therefore, the upper end of the keyboard 1 and the 8th end are the lower ends.
As shown in the figure, it is fastened with screws 7, and the center portions of both sides are held down by claws 6, so that no bending occurs even when the surface is pressed. In such a mounting state, since the frame 4 is not warped, the frame 4
The nameplate 3 fitted into the groove 8 will not be deformed.
Therefore, there is no gap between the nameplate 3 and the keyboard 1.

As is clear from the above explanation, the present invention provides the following effects.

(1) Since the ribs correct the warping of the frame during molding, it is possible to eliminate the gap between the nameplate and the keyboard.

(2) The provision of claws improves the support strength of the keyboard, and the keyboard surface does not sag when pressed.

(3) Since there are no warps or gaps, the appearance is good and the product quality is improved.

(4) Since it is only necessary to integrally mold the ribs and claws on the inner surface of the frame, the structure is simple, can be implemented at low cost, and exhibits excellent effects such as being useful.
