DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG. 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 figure, the balancer 12 includes a first ring 13 and a second ring 13 on the inner peripheral side upper surface and the outer peripheral side upper surface, respectively.
Of the first ring 13
Is higher than the second ring 14. Balancer 12
A first water injection port 16 is provided between the first ring 13 and the second ring 14 on the cover 15 provided above the first water injection port 16 and the hose 18 connects the first water injection port 16 and the electromagnetic water supply valve 17. It is connected.

The operation of the above structure will be described. When water is injected from the first water injection port 16 while the washing / dehydrating tub 1 is stopped, water flows between the first ring 13 and the second ring 14. The water collects from the second ring 14, flows along the outer circumference of the balancer 12, flows out to the outer peripheral wall of the washing / dehydrating tub 1, and removes dirt adhering to the washing / dehydrating tub 1. Momentum is weak because water drops from the entire circumference of the washing / dehydrating tub 1, but when a metal such as a stainless steel plate is used for the side wall of the washing / dehydrating tub 1, the outer surface of the side wall is flat and the momentum of the water is weak. Even dirt can be washed away.

When the washing / dehydrating tub 1 is rotated while rotating at a low speed, the water is spun to the outside by passing over the second ring 14 by the centrifugal force, splashing on the inner wall of the water receiving tub 4 and adhering to the inner wall of the water receiving tub 4. Dust and detergent can be washed off.

Next, a second embodiment of the present invention will be described with reference to FIG. 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 figure, the water receiving tank 19 has a second water injection port 20 on the side wall from the water receiving tank 19 toward the washing / dehydrating tank 1.
Is provided, and the second water injection port 20 and the electromagnetic water supply valve 17 are connected by a hose 21.

To explain the operation of the above construction, when the washing / dehydrating tub 1 is rotated at a low speed and water is poured from the second water injection port 20, the dirt attached to the washing / dehydrating tub 1 can be removed. Since the washing / dehydrating tub 1 rotates at a low speed, the injected water falls along the side wall of the washing / dehydrating tub 1,
The entire side wall can be cleaned. Further, when the washing / dehydrating tub 1 is rotated at a medium speed and water is poured from the second water injection port 20, the water is repelled by the washing / dehydrating tub 1, and the scattered water is flown to the water receiving tub 19 and then to the water receiving tub 19. It is possible to wash off adhered dirt and the like. Since the inner surface of the water receiving tank 19 is flat, even a small amount of water can be drained off.

As described above, since the water injection into the washing / dehydrating tub 1 is concentrated only at one place, innumerable ribs are provided vertically and horizontally for reinforcement like the outer surface of the side wall of the washing / dehydrating tub 1 which is strong in strength and made of resin. Dirt can be washed away even when running.

Next, a third embodiment of the present invention will be described. The electromagnetic water supply valve 17 of FIG. 1 or FIG. 2 is designed to inject water from the first water injection port 16 or the second water injection port 20 after the washing process is completed and drained, and before the dehydration process is started. The other structure is the same as that of the first or second embodiment.

The operation of the above structure will be described. After the washing process is completed and the water is drained, and before the dehydration process is started, dirt, residual detergent and the like are in a state of containing water. Adhesiveness to 4 is weak, and it can be washed off with a small amount of water. Once the dirt and detergent that have adhered have dried, it is impossible to wash them off with just water.

In addition, by running the detergent adhering to or remaining in the washing / dehydrating tank 1 and the water receiving tank 4 out of the machine before the dehydration, it is possible to prevent bubbles from being disturbed at the time of starting the dehydration, and also to perform the washing / washing. The bubbles adhering to the upper portions of the dehydration tank 1 and the water receiving tank 4 are also drained off, and the residue of the detergent component in the water receiving tank 4 is reduced, so that the rinsing efficiency can be improved.

Next, a fourth embodiment of the present invention will be described. The electromagnetic water supply valve 17 of FIG. 1 or 2 is configured to inject water from the first water injection port 16 or the second water injection port 20 when the washing / dewatering tank 1 is rotated by inertia after the final dehydration process. ing. Other configurations are the above first or second
Is the same as the embodiment described above.

The operation of the above structure will be described. Since the rinsing process is performed before the final dehydration process, less dirt and detergent remain in the portion below the water level supplied.
Only stains brought above the water level due to bubbles need to be washed away, and a small amount of water can be used for washing.

[0028]

As described above, according to the present invention, the first ring and the second ring are provided so as to project on the inner peripheral side upper surface and the outer peripheral side upper surface of the balancer provided in the upper part of the washing / dehydrating tank, respectively. Is higher than the second ring, and a first water inlet is provided between the first ring and the second ring from the cover provided above the balancer. Since the water supply valve is connected by a hose, water is poured from the first water injection port while the washing and dehydrating tank is stopped, so that water overflows from the second ring and is transmitted to the outer circumference of the balancer to perform washing and removal. It is possible to wash away dirt and residual detergent separated from clothes attached to the washing / dehydrating tank with a small amount of water, and to pour water while rotating the washing / dehydrating tank at low speed. Centrifugally forces the second ring Ri Beyond being sprinkled on the outside, dirt adhered to the water-receiving tub inner wall, it is possible to drop flowing detergent, it is possible to suppress the generation of black mold.

A second water injection port is provided on the side wall of the water reception tank from the water reception tank containing the washing and dehydration tank toward the washing and dehydration tank, and the second water injection port and the electromagnetic water supply valve are connected by a hose. Therefore, by pouring water from the second water inlet while rotating the washing / dehydrating tub at a low speed, dirt and residual detergent separated from clothes attached to the washing / dehydrating tub can be washed off with a small amount of water, In addition, by pouring water from the second water inlet while rotating the washing / dehydrating tub at medium speed, the water is repelled by the washing / dehydrating tub, and the scattered water jumps to the water receiving tub, and the dirt attached to the water receiving tub, etc. Can be washed away, and the generation of black mold can be suppressed.

After the washing process is completed and drained, the water is injected from the first water injection port or the second water injection port before entering the dehydration process.
Before entering the dehydration process, since dirt and residual detergent have weak adhesion to the washing / dehydrating tank and the water receiving tank, it can be washed off with a small amount of water.

After the final dewatering process, when the washing / dehydrating tub is rotating by inertia, water is injected from the first water injection port or the second water injection port. Since the rinsing process is performed, there is little dirt or detergent residue below the level of water supplied, and it is sufficient to wash away only dirt carried above the water level due to bubbles, etc. .
