Description

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

This type of washing machine usually has a washing tub and a dewatering tub that are integrally molded.

For dehydration, clothes are placed in a dehydration cylinder that rotates inside the dehydration tank.
Centrifugal dehydration is performed.

The opening of this dehydration tank has an entrance for throwing clothes into the dehydration cylinder, but it is necessary to prevent the clothes from falling outside the dehydration cylinder. The opening of the water tank is equipped with a cover that has a hole in the center with a diameter similar to the opening diameter of the dehydrator to guide the clothes into the dehydrator and prevent them from falling outside the dehydrator. .

Since the dehydrator itself is supported by a shock absorbing device, it is easy to shake the head, and small items of clothing may fall out of the dehydrator through the slight gap between the hole in the cover and the outer diameter of the dehydrator. In this case, the receiver cover is removable so that dropped clothing can be taken out relatively easily.

Since the cover of this receiver is located above the dehydrating cylinder and needs to be accommodated in a narrow space below the dehydrating lid, it necessarily has a flat shape.

That is, in the conventional receiver, the cover was often placed horizontally in the shape of a flat plate.

When dehydrating, wet clothes are carried to the dehydration bottle, but at this time a large amount of the water bottle remains on the cover of the receiver, and when the dehydrated clothes are taken out after dehydration, the clothes are wet again with the water droplets, In addition, the receiver has the disadvantage that the cover surface tends to become dirty due to residual water droplets.

Additionally, in the past, this receiver had an inclination in the direction of water flowing into the cleaning tank in order to return the water droplets on the cover into the cleaning tank, but as mentioned above, the dehydration lid and the top of the dehydration cylinder Due to the necessity of arranging the pipe in a flat space between the pipes, a large slope cannot be obtained, and the draining effect cannot be sufficiently exerted.

In this invention, instead of simply setting the slope of the cover so that the water flows into the cleaning tank, we have taken into account the possibility of increasing the slope. The flange and receiver of the dehydration tank are tilted to allow water to flow toward the abutment surface of the cover, increasing the draining effect, and the top surface on the opposite side of the washing tank is designed to improve strength while forming a water channel. was formed.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a tank, in which a washing tub 2 and a dehydrating tub 3 are integrally molded from resin.

Reference numeral 4 denotes a dehydration cylinder, which is rotatably disposed within the dehydration tank 3 and centrifugally dehydrates the cloth inside.

A cover 5 is detachably fixed to the periphery of the upper opening of the dewatering cylinder 4.

The receiver cover 5 has an input hole 6 having a size approximate to the outer diameter of the dewatering cylinder 4 in its center portion.

Further, the cover 5 of the receiver usually has a safety lid 7 to close the insertion hole 6.

Here, conventionally, the part covered by the safety lid 7 is covered by the cover 5.
The part was sloped so that water could flow toward the input hole 6.

However, an annular projection 8 is provided on the outer periphery of the safety lid 7, and the upper surface of the outer periphery of the annular projection 8 has conventionally been flat.

However, according to this embodiment, the upper surface 9 on the side of the washing tub 2 is inclined toward the washing tub 2, the upper surface 10 on the front side and the upper surface 11 on the opposite side to the washing tub 2 are inclined forward, and the receiver is tilted toward the washing tub 2. Seam 13 between the front end and the front flange 12 of the tank 1
By making it into a shape that flows into the upper surface 10 of the front
can be tilted over a relatively short distance, making it possible to have a large slope, which has a great drainage effect.

Further, on the flange 14 of the tank 1 on the side opposite to the washing tub 2 side, there is a mounting screw 16 for tightening the body 15.
A relief part 17 is provided, and a recess 18 is also formed in the cover 5 of the receiver to allow the relief part 17 to escape further.

In order to form this recess 18, the upper surface 11 is provided with a water channel 19 having a substantially U-shaped cross section to improve the flow of water and improve the strength of the upper surface 11.

In FIG. 3, arrows indicate the direction of inclination of the upper surfaces 9, 10, 11.

As described above, according to the present invention, the upper surface of the cover on the washing tub side of the receiver is tilted toward the washing tub side, and the upper surface of the front side and the upper surface of the opposite side from the washing tub are tilted forward, thereby achieving a draining effect. In addition, by making the upper surface on the opposite side from the washing tub a water channel with a substantially U-shaped cross section, it is possible to improve the draining effect and the strength.
