Description

[Detailed Description of the Invention] The present invention relates to the structure of an electric washing machine in which a washing tub and a dehydrating tub are arranged side by side.

Conventionally, in this type of washing machine, if the drain channels for the washing tub and the dehydration tub were formed separately, installing the drain pipes would be troublesome, and if the drain pipes were shared, the drain channel switching device would be complicated. was.

The present invention is an improvement on this, and the present invention will be explained with reference to an embodiment shown in the figure below. 1 is a washing tub, 2 is a dehydrating tub, and these washing tub 1 and dehydrating tub 2 are integrally molded from synthetic resin. An overflow channel 3 of the washing tub 1 is formed between the washing tub 1 and the dewatering tub 2 by using a part of each side wall.

A drain port 22 is formed in the lower part of the side wall 21 of the dewatering tank 2 facing the overflow channel 3, and the overflow channel side of the opening is designed to prevent water from flowing into the dewatering tank 2 side when draining water from the washing tub 1 side. A valve body 4 made of an elastic material is provided to prevent the overflow, while a drain port 11 is formed on the lower side of the washing tub 1 facing the overflow channel 3, and the drain port is bellows made of an elastic material such as synthetic rubber. A cylindrical drain valve 5 is installed in the shape of a cylinder and a coil spring or the like is installed between both ends.

The lower end of the overflow channel 3 protrudes downward to surround the drains of the washing tub 1 and the dewatering tub 2, and an annular rubber backing 31 is attached to the protruding edge. The plate 6 is attached to a receptacle of a required depth with the bottom surface 62 facing the cylindrical drain valve 5 by screws or the like.

Further, a coil spring 51 is provided on the lower side of the cylindrical drain valve 5.
The receiver is equipped with an annular seat 52 that also serves as a seat, an arm is extended from one side of the annular seat 52, an operating shaft 7 is linked to the arm, and the operating shaft 7 is inserted into the overflow channel 3. The upper end thereof is connected to an operation handle of an operation panel (not shown).

With the above configuration, when the washing tub 1 overflows, water passes through the overflow channel 3 and drains to the outside via the drain port 61 of the dish 6, and the water from the dehydration tank 2 side also overflows from the drain port 22 through the valve body 4. The water flows into the channel 3 and is similarly drained to the outside through the drain port 61 of the tray 6.

On the other hand, on the washing tub 1 side, during washing, the cylindrical drain valve 5 is pressed against the bottom surface 61 of the tray 6, so that the drain port 11 is blocked, and the water in the tub does not drain out. There is no possibility that external water flowing through the pans 6 will flow into the pans.

Next, when draining the washing tub 1, operate the handle of the operation panel to pull up the operation shaft 7, and when one side of the cylindrical drain valve 5 is lifted against the spring 51, the annular seat 52 holds the other side. It is tilted diagonally as a fulcrum, and a gap is created between the receiver and the bottom surface 61 of the dish 6, through which the water in the tank body 1 can be drained to the outside through the drain port 61 of the dish 6. .

As explained above, the overflow channel 3 can be used as a part of the drainage channel of the washing tub 1 and the dewatering tub 2, and the structure is simple, and assembly and inspection are easy, and costs can be reduced.
