DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. FIG. 2 shows a two-tub washing machine according to an embodiment of the present invention. Reference numeral 11 denotes a tank constituting a washing tub and a dehydrating tub (both not shown). It is placed on the top of the . 13 is a washing lid, 14 is a dehydration lid, and 15 is a mounting member such as a mounting frame installed on the upper front surface of the tank 11. This mounting member 15 includes a decorative plate 17 on which operation buttons 16 for various electrical components are arranged. are attached by joining.

FIG. 3 shows how to install the mounting member 15 etc. for attaching the decorative board 17 to the tank 11. By providing an upwardly rising wall 20 in the upper part, a space 21 for storing electrical components is provided, and a printed circuit board unit 23 to which a plurality of operation switches 22 are attached is stored in this space 21. This printed circuit board unit 23
is attached to the decorative board 17, and the decorative board 17
is attached to a window hole 24 of a mounting member 15 such as a mounting frame. The decorative board 17 also has a hole 2 into which the operating switch 22 of the printed circuit board unit 23 is inserted.
5, and a display board 26 displaying operating instructions etc. is mounted on the front of the decorative board 17 in a watertight manner, and holes 27 provided in this display board 26 are provided with watertight operation buttons 16 for various electrical components. is installed. Reference numeral 28 denotes an eaves section provided on the upper part of the decorative board 17, and this eaves section 28 has a width that covers the entire electrical component.

FIG. 4 shows the state in which the various members shown in FIG. 3 are installed, in which a mounting member 15 such as a mounting frame is mounted on the upper front surface of the tank 11 by slanting and concave-convex fitting, and the decorative board 17 is attached to the top of the front surface of the tank 11. It is attached so that the periphery is surrounded by the attachment member 15. The reason why the decorative board 17 and the mounting member 15 are formed separately in this way is that
This is to make the design stand out by changing each color. In this case, if the decorative board 17 and the mounting member 15 are formed separately, it is necessary to join them together. Therefore, if there is such a joint, detergent liquid or water droplets may enter from this joint, resulting in the problem shown in A. If the eaves section 28 described above is not provided, the dropped detergent solution and water droplets will fall onto the operation switch 22 of the printed circuit board unit 23, causing insulation deterioration. In this case, although the front surface of the operating switch 22 is waterproofed by the flexible piece 16a provided on the operating button 16, it is in a state of protection against water droplets and the like falling from the upper part. However, in one embodiment of the present invention, an eaves section 28 for letting the dripping liquid escape is provided on the upper part of the decorative board 17 so as to cover the upper part of the printed circuit board unit 23, which is an electrical component, and the eaves section 28 is provided with the above-mentioned mounting part. Groove 2 that clamps the window end of member 15
8a is provided over the entire width of the eaves portion 28, so even if detergent liquid or water droplets infiltrate from the joint between the decorative board 17 and the mounting member 15, the infiltrated detergent liquid or water droplets will flow to the left and right sides of the groove 28a. It can be dripped downward from the edge. Furthermore, if there is a large amount of detergent liquid or water droplets, or if water is sprayed forcefully from the front, it will climb over the protrusion 28b that constitutes the groove 28a. If it is made long enough to prevent water droplets etc. from splashing on the printed circuit board unit 23, even if the protrusion 28b is climbed over, water droplets etc. will not splash onto the printed circuit board unit 23. Further, as a structure in which the size of the hanging end of the eave part 28 is shortened and the same effect is obtained, an upwardly rising portion 28c is provided at the hanging end of the eave part 28, which is provided so as to hang down when the decorative board 17 is installed at an inclined angle. There is a configuration that provides. In this configuration, even if the dimensions of the hanging ends of the eaves section 28 are shortened, water droplets, etc. are guided to the left and right ends of the eaves section 28, and the printed circuit board unit 2
It doesn't take 3. Also, in Figure 4,
In order to more reliably prevent water droplets etc. from splashing on the printed circuit board unit 23, the rising portion 28
A hanging portion 28d is further extended to the tip of c.

FIG. 5 is a perspective view of the eaves section 28 seen from the back side of the decorative board 17. At the left and right ends of the eaves section 28, as is clear from FIG. It has been established that In this case, if there is no hanging piece 28e, the water flowing to the left and right sides of the eaves section 28 will not flow into the back side of the eaves section 28 from the left and right ends of the eaves section 28 if the force is strong. , protrusion 28b
Since the flow of water that has flowed over the area is slow, there is a risk that the water may flow into the back side of the eaves part 28 from the left and right ends of the eaves part 28. however,
Hanging pieces 2 hanging downward from the left and right ends of the eaves part 28
By providing 8e, even water whose flow is slow can be reliably dropped downward at the end of the eaves part 28.

In the above embodiment, the decorative board 17 and the mounting member 15 are formed separately, but a case where the decorative board 17 and the mounting member 15 are integrated and the upper end is joined to the tank 11 is also possible. The rising portion 28c and the hanging piece 28e have the same effect as in the above-mentioned embodiment with respect to intrusion of detergent liquid, water droplets, etc. from the joint B of the tank 11 in the above-mentioned embodiment. Further, even if the groove 28a on the side of the decorative plate 17 is provided on the side of the mounting member 15 such as the mounting frame, the same effect as in the above embodiment can be obtained.

Effects of the Invention As described above, according to the present invention, an eaves portion having a width that covers the entire electrical component is provided on the upper part of the decorative board that is attached to the mounting member, so that the mounting area between the decorative board and the mounting member is provided. Even if water infiltrates the electrical components, the eaves can prevent the water from splashing onto the electrical components, thereby eliminating the problem of water heating up the electrical components and causing insulation deterioration. Since only the eaves portion is provided, it is extremely simple, and therefore it is possible to obtain a highly safe product at low cost. In addition, an upwardly rising part is formed on the eaves to divert the flow of water to both the left and right ends, so the length (dimensions) of the eaves can be shortened, allowing storage in a designated space. .
