Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a display device for a washing machine or the like used in a general household.

Conventional Structure and Problems Conventionally, in this type of washing machine, etc., the mounting structure of a light device such as a light emitting diode (hereinafter referred to as LED) 1 and the structure of the display board 2 are as shown in FIG.
A method has been adopted in which a signal is displayed to the outside of the machine by using a transparent or semi-transparent part 4 formed in the display board 2 with the tip of the light emitting part of the LED 1 fixed to a printed circuit board 3 or the like. Further, in order to prevent the LED 1 from being misaligned with the printed circuit board 3, a structure has been adopted in which a holder that wraps around the LED 1 is used to prevent the LED 1 from being misaligned on the printed circuit board 3. Conventionally, this display board 3 was formed of a resin molded product, etc., so aligning the head of the LED 1 and the semi-transparent part 4 on the display board 3 was a relatively easy positioning of two parts. It was hot. In the display board 3, which is made of a resin molded product, generally, the operation part such as a push button and the display part such as the LED 1 are close to each other, so there is always a gap between the movable part such as the push button.

Since washing machines and the like use water and detergent, water entering through these gaps can lead to poor insulation of electrical components such as switches, causing practical problems. For this reason, the structure does not create any gaps,
In addition, it was a problem to ensure the alignment of the display such as LED1.

Purpose of the invention The purpose of the present invention is to solve these conventional problems, create a waterproof structure, prevent the positional shift of the display of LEDs, etc., and provide reliable display.

Structure of the invention This invention provides a frame that surrounds the through hole in the panel, forms slanted ribs on the inner surface of this frame, holds a printed circuit board on which a light device such as a light emitting diode is attached in a holder, and uses the ribs as a guide to hold the holder. engage the frame,
By tightly fixing the sheet-like decorative board to the panel, the positioning of the lamp and the sheet-like decorative board can be performed without causing any practical problems to the sheet-like decorative board.

DESCRIPTION OF EMBODIMENTS Next, an embodiment of the present invention will be described based on the accompanying drawings. In Figures 2 to 6,
The LED 1 is held by a holder 7 and fixed on the printed circuit board 3.

This printed circuit board 3 is fixed to a boss 8 provided on the panel 5 with screws 9.

Now, even if the panel 5 and the sheet-like decorative board 6 are positioned securely, there may be variations in assembly between the holder 7 and the printed circuit board 3, and between the screw tightening hole 10 on the printed circuit board 3 and the boss 8. This is the easy part. Therefore, the holder 7 and the sheet-like decorative board 6
The through hole and the transparent portion 11 are likely to be misaligned due to variations in assembly. Now panel 5
A frame 12 is provided in the portion where the upper LED 1 is located, and a plurality of ribs 13 are provided within this frame 12. As shown in FIG. 5, even if the holes 10 for tightening the screws 9 and the bosses 8 are matched, it is difficult to match the outer periphery of the holder 7 and the inside of the ribs 13 in the frame 12. , through hole, transparent part 11
The ribs 13 of the panel 5 and the ribs 13 of the panel 5 are determined relatively constant by setting the resin molding mold dimensions, but between the holder 7 and the printed circuit board 3,
The position between the hole 10 for tightening the screw 9 and the position of the boss 8 may vary during assembly, so the tip of the LED 1 and the through hole,
Misalignment with the transparent portion 11 is likely to occur. here,
By utilizing the slight bending of the legs 14 of the LED holder 7 and inserting the holder 7 guided by the ribs 13, the tip of the LED 1 can be aligned with the through hole and the transparent portion. By placing a slight distance between the surface of the rib 13 that is in close contact with the sheet-like decorative board 6, when the thin sheet-like decorative board 6 is pressed against the outside, the corner portions 15 come into contact with the sheet-like decorative board 6.
This can prevent marks or scratches on the surface.

Further, by providing the slope 16 at the other end of the rib 13, even if the holder 7 is misaligned during the assembly, the holder 7 is guided along the rib 13 and fits, and the alignment during assembly can be ensured. becomes.

Effects of the Invention As is clear from the above-mentioned embodiments, according to the present invention, the misalignment that occurs when assembling the through hole, transparent part, front panel, holder, and printed circuit board on the sheet-like decorative board can be corrected by the frame and its inner surface. The holder is flexed and positioned by the ribs provided on the lamp, and the light emitting part of the lamp is aligned with the through hole or transparent part on the sheet-like decorative board, and the holder can be securely held by the ribs.
