Now, according to the washing machine having the above configuration, the following effects can be obtained.

(a) Support g11f having a support part 15 that supports the hanging body 64: Since it is attached to the upper end of the outer box 1 and the base plate 2 having the legs 5 is attached to the lower end of the outer box 1, There is no need to weld separate support plates or legs to the outer box 1 as in the past, and the outer box 1 can be formed into a simple rectangular cylindrical shape with open top and bottom surfaces. It may be possible to construct it from a decorative steel plate, thereby omitting a painting process. That is, in the case of a configuration in which the support plate and legs are welded to the outer box, if the outer box is made of decorative steel plate, the coating on the decorative steel plate may peel off during welding, or the welding strength may be insufficient. Due to a problem, the outer box could not be made of decorative steel plate.

(b) Since the four leg parts 5 are integrally molded on the base plate 2, and the four support parts 15 are integrally molded on the support plate 11, conventionally, the legs and Unlike the case where a large number of parts such as supports are attached, the number of parts can be significantly reduced, parts management can be made easier, and there is no need for welding of legs and supports as in the past, making production easier. It can also improve sexual performance.

(Q) The entire circumference of the upper and lower opening edges of the outer box 1 can be reinforced by the base plate 2 and the support plate 11, which have a substantially rectangular frame shape, so that a robust structure can be obtained without using a separate reinforcing material.

(α) Since the water injection channel 18 is formed in the support plate 11, the water discharged from the water supply solenoid valve 43 can be guided into the rotating fvJ 30 with good sound by the water injection channel 18, and a separate member is not required as the water injection channel. Therefore, it can contribute to reducing the number of parts.

(e) Operation box 4 with a water-shielding protrusion 19 provided in front of the water injection channel 18 and forming a water-shielding wall together with the water-shielding protrusion 39 of the cover 37
0 can be reliably prevented from entering. 1(f)
The operation box 4 is attached to the support plate 11 with the springs y & m4i of the cover 37.
Since the left and right walls 20, 21 and the back wall 22 that make up the 0 are integrally molded, unlike the conventional case where the panel board or back board was separately attached to form the operation box, it is not necessary to attach separate parts. This troublesome work can be made unnecessary, and the ease of assembly can be improved.

(g) A groove-shaped engagement portion 10 is formed on the base plate 2 by the 11i-th protrusion piece 8 and the second protrusion piece 9, and the first protrusion piece 2 is formed on the support plate 11.
4 and the second projecting piece 25 to form a groove-shaped engagement part 26,
These engaging parts 10 and 26 can engage and temporarily hold the upper and lower ends of the lid body 44, contributing to improved ease of assembly.

Since the handle portions 27 and 27 are formed on the support plate 11,
The finger parts 27 and 27 can be obtained by being included in the molding of the support plate 11, so when a recessed part for a hand is made in the outer case 1, or a body is provided for a separate hand in the outer case 1. The number of manufacturing steps is significantly reduced compared to the conventional method.

In the above embodiment, the outer box 1 is made of a so-called decorative steel plate that has been painted, but the outer box 1 may be made of an unpainted general steel plate and then painted.
Since the outer box 1 has a simple shape without conventional legs or supports, it can be easily painted.

The detailed invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without departing from the gist.

〔Effect of the invention〕

As explained above, the present invention can obtain the following effects.

(1) Unlike the conventional case, the outer box can be formed into a simple rectangular cylindrical shape without legs or supports, so the coating process for the outer box can be simplified.

(11) Compared to the conventional method of welding many legs and many supports to one outer box, the number of parts can be greatly reduced, parts management can be made easier, and welding work is not required. It is also possible to improve the productivity.

(Ill) Since the support plate is provided with a narrow water injection channel and a water-shielding ridge at the support part, the water injection channel can effectively inject water into the tank, etc., and water droplets generated above the tank can be prevented from entering the operation box. This can be prevented by the water-shielding ridges, and since the water injection channel and the water-shielding ridges are integrally molded on the support plate, the number of manufacturing steps can be significantly reduced.

2. Also, since the wall that forms the operation box with the panel plate of the cover is integrally molded on the support board, it is easier to assemble than when the operation box is formed by attaching a separate panel plate or back plate. This will greatly improve overall productivity.

伎) The base plate and the support plate are each formed into a substantially rectangular frame shape to form the outer box 1.
Since the outer box is attached to the lower and upper ends of the box, the outer box can be reinforced and made more robust.
