Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine for both dehydration and washing equipped with a water supply device for supplying water to a washing and dewatering tub, and particularly to improve rinsing performance.

[0002]

2. Description of the Related Art Conventionally, this type of combined washing machine for dehydration has been constructed as shown in FIG. The configuration will be described below.

As shown in the figure, the water receiving tub 1 includes a washing / dehydrating tub 5 in which a clutch switching device 2 and a motor 3 are disposed below and a rotary vane 4 is rotatably provided at the bottom. .
At the time of dewatering, the washing shaft 6 for rotating the rotary blades 4 and the dewatering shaft 7 for rotating the washing and dewatering tub 5 rotate at the same time, and at the time of washing, the changeover clutch 8 works to move only the washing shaft 6 through the gear shaft 9. Rotates.
The tank cover 10 is arranged above the water receiving tank 1, and the top plate 11 is arranged above this tank cover 10. The water supply valve 12 is connected to an external hose 13 to supply water to the washing / dehydrating tank 5. The water supply hose 1 communicating with the water supply valve 12
4 and the water supply port 15 are provided, and the water supply port 15 is fixed to the top plate 11. The rotation of the motor 3 is transmitted to the gear shaft 9 via the V belt 16 and the pulley 17.
The rod 18 suspends and supports the water receiving tub 1 on the main body 19 of the washing machine.

[0004]

In such a conventional structure, when rinsing, the water supply valve 12 is operated to inject water from the water supply port 15 into the clothes in the washing / dehydrating tub 5, the water supply port 1 is used.
Since 5 is fixed to the top plate 11, water can be poured only from the same height and from a fixed direction, and since the water receiving tub 1 is suspended and supported by the washing machine body 19 via the rod 18, the washing / dehydrating tub If the height of the water receiving tank 1 varies depending on the amount of clothes in 11 or if the clothes are offset, the clothes are not flooded, so that the clothes cannot be sufficiently filled with water. However, there is a problem that rinsing becomes insufficient.

The present invention solves the above-mentioned problems, and makes it possible to sufficiently inject water into the clothes even if the amount of clothes or the position of the clothes in the washing / dehydrating tank during rinsing changes. Is aimed at stabilizing and improving.

[0006]

In order to achieve the above object, the present invention provides a water receiving tub containing a washing / dehydrating tub, a tub cover arranged above the water receiving tub, and a washing / dehydrating tub. The tank cover is provided with a water supply valve for supplying water, and the tank cover has a plurality of opening holes formed in an inner peripheral portion thereof and a cylindrical portion formed above, and a hollow portion communicating the opening hole and the cylindrical portion is provided inside. It is formed and the cylindrical portion of the tank cover and the water supply valve are connected by a hose as a means for solving the problem.

[0007]

According to the present invention, by the above-mentioned means for solving the problems, water is supplied at the time of rinsing through a plurality of opening holes formed in the inner circumference of the tub cover, so that the amount of clothes in the washing / dehydrating tub can be changed so that the water receiving tub Even if the position moves up and down, the water injection port is formed in the tank cover, so it is possible to always inject water into the washing and dewatering tank at a constant angle. Since water can be injected from the circumference, water can be sufficiently included in the clothes, and the rinse performance can be stabilized and improved.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The same components as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted.

As shown in the drawing, the tank cover 20 is disposed above the water receiving tank 1, and has a plurality of opening holes 21 formed in the inner periphery thereof and a cylindrical portion 22 formed above the opening. A hollow portion 23 that connects the hole 21 and the cylindrical portion 22 is formed inside. The top plate 24 is provided above the tub cover 20 and above the washing machine body 19, and is provided with a water supply valve 12 and a hose 25 that communicates with the discharge port 12a of the water supply valve 12. Is configured to communicate with the cylindrical portion 22 of the tank cover 20.

To explain the operation of the above structure, the water supply valve 12 operates during rinsing, water is supplied to the tub cover 20 via the hose 25, and washing and washing is performed from the opening hole 21 via the cylindrical portion 22 and the hollow portion 23. Water is poured into the dehydration tank 5. The clothes in the washing / dehydrating tub 5 are brought into close contact with the inner wall of the washing / dehydrating tub 5 by intermediate dewatering, and the water injection from the opening hole 21 formed over the entire inner circumference of the tub cover 20 is performed by the washing / dehydrating tub 5. 5
It can be fully included in clothes regardless of the unevenness of clothes inside. Further, since the positional relationship between the opening hole 21 and the washing / dehydrating tub 5 is always constant regardless of the amount of clothes, water can be poured into the clothes at a certain angle, and after the clothes are sufficiently water-filled, the clothes are dehydrated. By doing, a stable rinsing effect can be obtained.

[0011]

As described above, the present invention comprises the water receiving tank containing the washing / dehydrating tank, the tank cover arranged above the water receiving tank, and the water supply valve for supplying water to the washing / dehydrating tank. The tank cover has a plurality of opening holes formed in an inner peripheral portion thereof and a cylindrical portion formed above, and a hollow portion which communicates the opening hole and the cylindrical portion is formed inside the tank cover. Since the cylindrical portion and the water supply valve are connected by a hose, the water for rinsing can be sufficiently included in the clothes regardless of the amount of the clothes in the washing / dehydrating tank and the unevenness of the clothes. By doing, a stable rinsing effect can be obtained.
