Description

[Detailed Description of the Invention] The present invention relates to a washing machine panel mounting device for mounting a panel for installing switches and the like on the upper rear part of the tank.

The structure of this type of conventional panel installation is as shown in FIGS. 1 and 2, where 1 is a panel and 2 is a decorative board that covers the front surface of the panel 1.

The decorative board 2 has a built-in washing timer 3, a water level switching cock 4, and a dehydration timer 5.

Reference numeral 6 denotes a tank formed by integrally molding a washing tub and a dewatering tub, and its upper part is placed on top of a washing machine main body 7, and a panel 1 and a decorative board 2 are arranged at the rear of the tank 6.

Further, a washing lid 8 and a dehydrating lid 9 are placed on the washing tub and the dehydrating tub, respectively.

At the bottom of the washing machine main body 7, there are legs 1 that support the washing machine main body 7.
0 is installed.

To attach the panel 1 to the decorative board 2, attach the hook-shaped part 1 of the decorative board 2.
1 is hung on the protruding part 12 of the panel part, and the decorative board 2 is attached above the rear part of the panel 1 by fixing the boss 13 and the panel 1 with screws.

Moreover, the panel 1 and the tank 6 are attached as follows.

That is, as shown in FIG. 2, the protruding piece 14 provided facing rearward at the rear of the bottom of the panel 1 is inserted into the insertion hole 15 at the rear of the tank 6, and the round hole of the panel 1 is inserted into the front of the bottom of the panel 1. 16 and the tank 6 are fixed to the boss 17 using screws 18 or the like.

Another method is to fix the tank 6 and the panel 1 with screws or the like, although not particularly shown, instead of inserting the projecting piece 14 of the panel 1 into the insertion hole 15 of the tank 6.

In either case, the washing machine main body 7 and the hanging flange 19 of the tank 6 are fixed with screws, etc., and the rear upper surface of the tank 6 is
Panel 1 is placed on 0.

According to FIG. 2, when the protruding piece 14 of the panel 1 is inserted into the insertion hole 15 of the tank 6, the panel 1 does not shift in the vertical direction, but the panel 1 easily shifts in the front-rear direction with respect to the tank 6. Therefore, it is difficult to align the round hole 16 of the panel 1 and the boss 17 when installing the tank 6.

Also, the protruding piece 14 of the panel 1 and the insertion hole 15 of the tank 6
Since the panel 1 is not fixed, the rear surface of the panel 1 is curved in the longitudinal direction.

In addition, in the method of screwing the front and rear parts of the bottom of the panel 1 to the rear upper surface 20 of the tank 6, it is difficult to align the round hole 16 of the panel 1 and the boss 17 when installing the tank 6, making it difficult to assemble. This is not only bad, but screw installation requires more parts than the insertion method, which increases the number of man-hours and parts, and increases costs.

In addition, when the panel 1 is screwed to the rear surface of the rear upper surface 20 of the tank 6, a hole (
(not particularly shown), the screwing location was near the rear of the panel 1, making the screwing work difficult.

This invention suppresses the curvature in the longitudinal direction of the back of the panel,
This eliminates the need for positioning when screwing the panel and tank together, and eliminates the need for screwing at the rear of the rear upper surface of the tank, thereby improving workability. Examples thereof will be described below.

In FIGS. 3 to 7, an escape hole 21 is provided on the rear surface of the panel 1 for passing the protruding piece 14 and the outer shape of the insertion hole 15 of the tank 6, and a relief hole 21 is provided on the front surface of the bottom surface of the panel 1. To attach the tank 1, a round hole 16 is provided for screwing to the boss 17, and the panel 1 is placed on the rear upper surface 20 of the tank 6.

Next, the relationship between the protruding piece 14 and the insertion hole 15 of the tank 6 will be explained in detail.

The protruding piece 14 has an integral claw 22 for engaging with the inner surface of the insertion hole 15, and a reinforcing rib 23 is integrally formed to increase the bonding strength between the panel 1 and the protruding piece 14. .

The protruding piece 14 is integrally formed with a step 24 located one step higher than the bottom of the panel 1.
Water that has entered the tank is prevented from leaking to the outside through the escape hole 21, and flows into the tank 6 through a drain hole (not shown) in the bottom of the panel 1.

Further, there is a relationship L>1 between the width 1 of the claw 22 and the width of the hollow portion 25 of the protruding piece 14, so that the claw 22 is easily bent downward, and the protruding piece 14 insertion hole 15
The claws 22 can be easily lowered when inserted into the body, making it easier to insert.

FIG. 7 shows the details of the insertion hole 15, and its inner surface has
It has a stepped portion 26 for engaging the claw 22.

The engagement between the pawl 22 and the stepped portion 26 eliminates the back and forth, left and right wobbling of the panel 1 on the top surface of the tank 6, and prevents the screws between the front of the bottom of the panel 1 and the front of the rear top surface 20 of the tank 6. It is fixed with a stopper.

The insertion hole 15 is integrally formed with an inverted U-shaped flange portion 27 at the rear of the tank 6, and this flange portion 27 is subjected to a force that causes it to bend backward due to the influence of the washing machine main body 7.

However, due to the engagement between the pawl 22 and the stepped portion 26, the flange portion 27 does not bend.

As described above, according to the present invention, the protruding piece provided integrally with the panel has a claw that engages with the step on the inner surface of the insertion hole when the tank is inserted into the insertion hole. There is no rattling between the panel and the tank, and the panel can be positioned at the same time by simply inserting a protruding piece, eliminating the need for a separate positioning operation and improving the workability of tightening screws.

Furthermore, the engagement between the pawl and the stepped portion can prevent the inverted U-shaped flange at the rear of the tank top surface from bending, thereby stabilizing product quality.
