BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine in which a washing tub is supported in an outer box by an elastic suspension mechanism so that washing and dehydration can be automatically performed.

[0002]

2. Description of the Related Art Conventionally, in a fully automatic washing machine, a washing tub is stored in an outer box while being supported by an elastic suspension mechanism, and one end of a drain hose is connected to a drain valve provided at the bottom of the washing tub. Also, the other end side portion is extended from the lower portion of the side wall of the outer box to the outside so as to drain the washing tub. One end of the drainage hose is fixed to the base plate provided at the bottom of the outer box,
The other end portion is adapted to be extended through a selected one of outlets provided on the lower left and right side walls of the outer box.

The prior art will be described below with reference to FIGS. 9 and 10. FIG. 9 is a perspective view from the bottom side when extending from the lower part of the left side wall of the outer box, and FIG. 10 is a perspective view from the bottom side when extending from the lower part of the right side wall of the outer box.

In FIGS. 9 and 10, 1 is an outer box, 2 is a base plate made of plastic provided in the lower part of the outer box 1, and 3 is a washing tub (not shown) housed in the outer box 1. It is a drive mechanism for driving the rotating tank and the stirring body inside. Further, 4 is a drain hose for draining the inside of the washing tub, which is a single bellows-shaped hose, one end of which is connected to a drain valve (not shown) provided at the bottom of the washing tub, and the other end is connected to the outer case 1 The water is drained by discharging it from the outside.

Reference numeral 5 is a fixing portion provided on the base plate 2 so as to fix one end side portion of the drain hose 4, and 6 and 7 are base plates 2.
The left and right outlets are formed so as to be cut out from the bottom side. Reference numerals 8 and 9 are left and right guide portions of the drain hose 4 provided between the fixed portion 5 and the left outlet portion 6 and the right outlet portion 7.

With this structure, when the other end portion of the drain hose 4 is extended from the lower portion of the left side wall of the outer casing 1, the drain hose 4 is folded in a U-shape at the right portion of the fixed portion 5. The left end portion 6 of the drain hose 4 is bent outward and mounted in the left guide portion 8 to extend the other end portion of the drain hose 4 to the outside. When the other end of the drainage hose 4 is extended from the lower portion of the right side wall of the outer casing 1, the drainage hose 4 can be mounted in the right side guide portion 9 as it is without being folded back from the right side portion of the fixed portion 5. The other end side portion of the drain hose 4 is extended from the right outlet portion 7 to the outside.

Therefore, when the drain hose 4 is pulled out from the left side of the outer box 1 and when it is pulled out from the right side of the outer box 1, the lengths outside the outer box 1 are significantly different because the paths are largely different. . When the drain hose 4 extending from the outer box 1 has a predetermined length, it must be folded back into a U-shape at the fixing portion 5 when it is taken out from the left side,
Since extra routing is required, the route of the drainage hose 4 becomes complicated and it takes time to change the extension direction. In addition, the drain hose 4 also becomes extra long because it is additionally routed.

On the other hand, in order to allow the drainage hose 4 fixed to the drainage valve to extend from the lower portions of the left and right side walls of the outer casing 1, a relatively large plastic base plate equivalent to this is provided under the outer casing 1. 2 must be provided. Further, in order to fix the drain hose 4 to the fixing portion 5 at one end side and then guide the intermediate portion from the left outlet portion 6 and the right outlet portion 7, the base plate 2 is fixed to the fixing portion 5 and Since the left and right guide portions 8 and 9 and the left and right outlet portions 6 and 7 are provided, the base plate 2 has a complicated structure and is expensive.

[0009]

SUMMARY OF THE INVENTION As described above, conventionally,
