Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a single-tub type washing machine for dehydration and dehydration, which is provided with a blocking body above the rotating tub to prevent laundry from flowing out.

In general, a single-tank type washing machine with dual dewatering function has a drainage section at the upper end of the rotary tank, which is formed by a gap between the peripheral wall and a balance ring attached to the inside. During dehydration, this rotary tank is rotated at high speed, and the centrifugal force is used to drain the water. It is raised along the peripheral wall to remove water from the drainage section.

The drainage section is set to the minimum necessary size during spin-drying in order to prevent washing liquid from overflowing as much as possible when the water level at the inner periphery of the rotating tank rises due to swirling water flow during detergent washing. .

Therefore, when overflow rinsing is performed by stopping the rotation of the rotary tank and rotating the pulsator while injecting water, there is little overflow from the drainage section, and water overflows over the top surface of the balance ring. For example, there was a risk that the slings, handkerchiefs, etc. would flow over the top surface of the balance ring and out of the tank along with the overflow water that went over the top surface of the balance ring.

Therefore, if a drainage hole is provided in the peripheral wall of the rotating tank, for example, by placing it below the balance ring, it will be possible to prevent small items such as clothing from flowing out. There was a problem in that the water level rose and the washing liquid was drained through the drain hole, reducing the amount of washing liquid in the rotating tub and significantly reducing the cleaning power.

The present invention was developed in view of the above circumstances, and is a device in which a balance ring is provided on the inner circumference of the upper part of a rotating tank serving as a washing and dehydrating tank, and a water-permeable blocking body is placed above the balance ring so as to face upward. It is an object of the present invention to provide a washing machine for dewatering and dehydrating, which is provided with a protruding structure to prevent laundry items from flowing out beyond the balance ring during overflow rinsing.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 and 2.

1 in the figure is the outer box of the washing machine main body, and its top opening is
It is covered with an upper cover 3 having a circular opening 2 in the center, and the opening 2 of the cover 3 is further closed with a lid 4.

The lid 4 is attached to the rear end of the opening 2 of the cover 3 by a hinge pin 5.

A resin-molded rotary tank 6 serving as a washing and dehydrating tank is disposed inside the outer box 1, and the rotary tank 6 is rotated or rotated by a motor 7 and a drive device 8 disposed at the bottom of the outer box 1. It is designed to stop.

A pulsator 9 is provided at the inner bottom of the rotary tub 6 and is driven by the motor 7 and drive device 8 to generate a swirling water flow in the rotary tub 6 for washing.

Now, the motor 7 and the drive device 8 are fixed to a support plate 10, and this support plate 10 is elastically suspended from a partition plate 12 provided on the outer box 1 via an elastic suspension mechanism 11.

A balance ring 13 is provided on the inner periphery of the upper part of the rotating tank 5 by placing and fixing the outer periphery of a top plate 13a on the upper edge of the rotating tank 6. The centrifugal force acting on the ring 13 prevents the rotating tank 6 from whirling around.

Further, a gap is provided between the inner peripheral part of the rotating tank 6 and the balance ring 13, and a discharge part 14 for draining water in the rotating tank 6 during dewatering is connected to the gap on the upper surface plate 13a of the balance ring 13. It is set up so that it can be communicated with.

Then, a circular blocking body 16 having a plurality of slit-shaped water passage holes 15 is integrally molded onto the upper surface plate 13 a of the balance ring 13 along the inner circumference of the balance ring 13 so as to project upward. It is set up.

Next, the operation of this embodiment configured as above will be explained.

When the laundry to be washed is stored in the rotating tub 6 and the timer device is set and operated, a washing process consisting of detergent washing, draining, rinsing, draining, overflow rinsing, draining, and water is automatically performed. This section describes the action during overflow rinsing, which is directly related to this.

That is, when the pulsator 9 is rotated by the motor 7 and drive device 8 while injecting water into the rotating tank 6, the water level in the rotating tank 6 rises, and the amount of water injected exceeds the drain section 14 and the top plate 13a of the balance ring 13. The amount of water approximately equal to that is overflowed and drained to the outside of the rotating tank 6.

Since water overflowing over the top plate 13a of the balance ring 13 overflows through the water passage hole 15 of the blocking body 16, the blocking body 16 prevents the laundry from flowing out, and only the water overflows and overflows. A rinse is performed.

On the other hand, during washing, the position of the drainage part 14 is sufficiently high compared to the water level of the washing liquid during washing, and even if water overflows from this drainage part 14, the amount of water overflowing is small and a sufficient water level of the washing liquid is ensured. Since the product is washed with water, there is no reduction in cleaning power.

As described above, according to this embodiment, during overflow rinsing, the rotating bath 6 passes over the top plate 13a of the balance ring 13.
When the water in the rotating tub 6 overflows from the upper part of the rotary tank 6, the blocking body 16 prevents the laundry from flowing out.

Moreover, since water overflows from the entire circumference of the upper surface of the balance ring 13, lint such as lint and detergent foam floating in the rinsing water can flow out easily, shortening the rinsing time, and ensuring sufficient washing when washing with detergent. The water level of the liquid is maintained and the cleaning power does not decrease.

In this embodiment, the blocking body 16 is integrally formed on the inner circumference of the top plate 13a of the balance ring 13, but as shown in FIG. A plurality of shelf-shaped convex portions 17 may be integrally molded and protruded from the upper surface of the upper surface plate 13a at regular intervals.

Further, as shown in FIG. 4, a protrusion 18 directed inward may be provided at the upper end of the blocking body 16. In this case, the laundry is likely to be caught and the laundry may flow out. It is even more effective in preventing this.

Furthermore, in each of the embodiments shown in FIGS. 1 to 4, the blocking body 16
The convex portion 17 is integrally molded with resin or the like on the top plate 13a of the balance ring 13, and as shown in FIG.
3a and attach it to the top plate 13H with screws 20.
It may be fixed to.

As is clear from the above description, the present invention is a device in which a balance ring is provided on the inner circumference of the upper part of a rotating tank serving as a washing and dehydrating tank, and a water-permeable blocking body is provided above the balance ring. This prevents the laundry from flowing out with the overflowing water that overflows over the balance ring during overflow rinsing, and also prevents floating objects such as lint and detergent from overflowing from the entire circumference of the top surface of the balance ring. To provide a dehydrating/washing machine which allows bubbles to flow out easily and shortens rinsing time.
