Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a washing machine panel that houses the control section of a washing machine used in general households.

Conventional technology Conventionally, the panel mounting structure of this type of washing machine was
5 and 6, a washing tub 25 is installed inside the main body 24 of the washing machine, and a rear panel 27 with a power switch 26 installed inside the upper rear part.
At the front, there is a panel 29 in which a control section 28 is housed. This control section is equipped with electronic components that control the washing time and water flow, and needs to be protected against external forces by being waterproof and having a strong mounting structure for the panel section. Therefore, as shown in FIG. 5, the front part of the washing tub 25 has an opening 30.
The panel 27 was engaged with and fitted to both ends 31 and 32 of. Further, a mounting plate 33 on which a control 28 is attached to the panel portion 27 is fixedly attached to the panel 27 by welding or the like. Opening 3 at the front of the washing tub 25
An inverted U-shaped flange 34 at the front end 32 of the panel 27 is provided with a convex claw 35 and a rib 36.
, and the upper part of the rear end part 31 is brought into contact with the upper surface receiving part 37 of the washing tub 25, and the panel 27
It was engaged with a recess 39 of the washing tub 25 with several claws 38 arranged in the washing tub 25. Reference numeral 40 denotes a waterproof cover provided on the control 28 to prevent water from entering through the fitting gap 41 between the panel 27 and the washing tub 25.

Problems to be Solved by the Invention However, in the conventional configuration, the rear upper end of the panel 27 is placed on the upper surface receiving portion 37 of the washing tub 25 and a claw 38 is used to prevent the upper surface receiving portion 37 from protruding outward from the panel 27. Therefore, if the upper surface receiving portion 37 falls inward or is deformed, a gap 41 will occur in the fitting portion, making it easy for water to enter.

If a large amount of water enters the vicinity of the control 28 inside the panel 27, the waterproof cover 40 alone cannot prevent water from splashing on the live parts and condensation, which may deteriorate the insulation state. Further, if the upper surface receiving part 37 of the washing tub 25 is pushed from above, the fitting part tends to sink downward, and the claw 38 is easily removed from the washing tub 25 by hand, which may pose a safety problem.

This invention solves these conventional problems, securely locks the panel and washing tub, prevents water from entering the panel, and provides a strong structure that prevents people from touching the control part from the outside. Ensure proper installation,
This is intended to improve safety.

Means for Solving the Problems In order to achieve the above object, the washing machine panel of the present invention has a panel that covers the opening for housing the control unit at the upper front of the washing tub, which is locked at both ends of the opening.
The engaging portion of the panel that engages with the rear end of the opening has continuous ribs that sandwich the end of the opening, and a protrusion formed at the end of the rib engages with the lower end of the opening. This is a configuration that allows

Effect With the above configuration, the ribs and protrusions ensure that the edge of the opening that is close to the wall of the washing tub and is prone to splashing water is engaged with the panel, thereby preventing a large amount of water from flowing into the control section of the panel. can.

Embodiment An embodiment of the present invention will be described below based on the accompanying drawings.

1, 2, and 3, the front upper part of the washing tub 2 installed inside the main body 1 of the washing machine is shown in the washing tub 2.
A cavity 3 is formed between the inside and the front main body 1, the front main body 1 and the washing tub 2 are placed on the main body 1 by the washing tub 2 of the inverted U-shaped flange 4, and a wall part partitions the cavity 4 and the inside of the washing tub 2. 5 has a continuous stepped portion 6 facing the inside of the washing tub 2, and a hook-shaped stepped portion 7 on the side facing the cavity 3. A control part 8 for operating and controlling the time limit and water flow of the washing machine is attached to a boss part 9 and a panel 11 with screws 10 or the like. The front end of the partial panel 11 that engages with the front flange 4 of the washing tub 2 is fitted with a U-shaped flange 4 between claws 12 provided at the bottom and ribs 13 provided above. Further, the rear end of the panel 11 has a stepped portion 6 that fits into the wall portion 5,
A rib 15 is continuously formed which abuts the tip end 14 of the step 7 on the side of the cavity 3 opposite to the step 6. Protrusions 16 protruding toward the wall 5 are formed at several locations on the rib 15 and are fitted into the tip 14 of the wall 5. The panel 11 is fitted and locked onto the wall portion 5 by the protrusions 16 arranged on the panel 11, so that it cannot be easily removed. Thickness of step part of wall part 5 1
3 and the rib 15 of the panel 11 and the rib 1 that rests on the step 6
The 7 portions are made the same to prevent water from entering from inside the washing tub 2, and when the protrusion 16 is press-fitted into the stepped portion 14, the elasticity of the rib 15 is used to prevent water from entering the washing tub 2.
It has a structure in which a protrusion 16 that expands in the direction locks onto the step portion 7.

The projections 16 provided on the ribs 15 of the panel 11 are formed using a mold structure shown in FIG. Panel 11
The whole is divided by a mold 19 on the front side 18 and a mold 21 on the back side 20, but the protrusion 16 is formed by a slide mold 23 from the rib surface side 22 opposite to the protrusion 16 on the rib 15. It can be formed by removing the locking surface.

Effects of the invention Due to the fitting and locking structure of the panel and washing tub of this invention, the washing tub wall on the inner side of the washing tub is sandwiched between the ribs on both sides of the panel, and it comes into contact with the rib wall surface without any gaps. Moreover, since the locking with the washing tub is formed by the fitting of the protrusions arranged at partial intervals and the steps of the wall, the gap that occurs at the fitting part is suppressed and the washing process is improved. It prevents water from entering from the tank side and eliminates insulation deterioration and abnormal control operation. Furthermore, even if an external force is applied to the panel from the outside, the panel and washing tub are firmly attached, so it will not come off.
