Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to reduce vibrations caused by uneven loads on cloth by increasing the mass of the entire vibration system during dewatering.

Conventional single-type dehydrating washing machines do not allow the laundry to shift to one side during dehydration (
In order to reduce this vibration, a solid balance such as cast metal or concrete is installed on the upper circumference of the washing tub, or an annular fluid balancer with liquid sealed inside is installed. ing.

However, due to factors such as ease of carrying the device,
It is not possible to increase the weight of the balancer, and it is not possible to sufficiently reduce vibration.

As a result, the outer tub often collides with the exterior of the washing machine, causing the safety switch to activate and preventing normal dehydration.

The present invention solves the above-mentioned conventional defects by increasing the mass of the entire vibration system during dehydration, and one embodiment thereof will be described below with reference to the drawings.

In the figure, 1 is the exterior of the washing machine, 2 is the large number of overflow ports 3 at the top.
9, which is a tapered inner tank that opens upward and constitutes a washing tub and a dehydrating tub.

3 is an outer tank provided on the outer periphery of the inner tank 2, 4 is a rotary blade provided at the center bottom of the inner tank 2, 5 is a washing shaft with the rotary blade 4 fixed to one end, and the other end is a washing diameter pulley 6. is attached.

Reference numeral 7 denotes a dewatering shaft, one end of which is fixed to the bottom of the inner tub 2 by an appropriate method, and a dehydration subordinate pulley 8 is attached to the other end, and the inner diameter also serves as a bearing for the washing shaft 5.

One end of the dewatering shaft 7, which is fixed to the bottom of the inner tank 2, is formed into an inner plate shape, and this disc has a plurality of water passage holes 9.

Reference numeral 10 denotes a dewatering bearing provided at the bottom of the outer tub 3, which has a built-in clutch for switching between washing and dewatering.

Reference numeral 11 denotes a motor attached to the bottom of the outer tank 3. A washing main pulley 12 and a dewatering main pulley 13 are fixed to the motor shaft, and power is transmitted to a washing diameter pulley 6 and a dewatering slave pulley 8 via belts 14 and 15. will be carried out.

Reference numeral 16 denotes a drain port provided at the bottom of the outer tank 3, to which one end of a drain hose A17 is attached.

The other end of the drain hose A17 is connected to a drain outlet A18 bored in the lower part of the external device of the washing machine.

19 is an upper support fitting attached to the upper four corners of the external device of the washing machine; 20 is a lower support fitting fixed to the lower four corners of the outer tub 3; 21 is a shock absorber incorporating a spring and a friction damping device; 22 is a lower hemisphere The outer tub 3 is supported by an external device of the washing machine by means of a hanging rod 24 through which the upper hemisphere 23 is inserted.

Reference numeral 25 denotes an annular L-shaped flange extending upward from at least the overflow port 39 on the outer circumference of the outer tank 3, and forms a water storage tank 26 together with the outer peripheral wall of the outer tank 3.

27 is a water supply outlet bored in a lower part of the water storage tank 26, to which a drainage hose B28 is attached.

The other end of the drain hose B28 is branched into two via a solenoid valve A29, one of which is connected to a drain outlet B31 drilled in the lower part of the exterior of the washing machine via a solenoid valve B30, and the other is connected to a drain outlet B31 bored through an oil seal 32. It fits into the dewatering shaft 7 and communicates with the water passage hole 9.

33 is a water supply faucet equipped with a solenoid valve C34 in the middle, and the water supplied from the water supply faucet 33 is configured to be injected into the water storage tank 26.

Reference numeral 35 indicates a balance weight of an appropriate type fixed above the inner tub 2, 36 indicates legs, 37 indicates a washing water level, and 38 indicates laundry clothes.

Next, the operation of the above configuration will be explained.

When the solenoid valve C34 is opened during washing, the water supplied from the water supply faucet 33 is injected into the water storage tank 26, and at this time, the solenoid valve A29 is open and the solenoid valve B30 is closed.
Depending on the water level, the water injected into the water storage tank 26 passes through the water supply outlet 27, the solenoid valve A29, the drain hose B28, and the water passage hole 9 provided in the dewatering shaft 7, and then moves into the inner tank 2.

When the water level of inner tank 2 reaches washing water level 37, press the pressure switch (
(not shown) closes the solenoid valve C34, water supply is stopped, and washing is performed.

The state is shown in FIG. At this time, due to the water level, the water in the water storage tank 26 remains as it is, and the flange 25
Water will not overflow as long as it is at least higher than the overflow point.

In the case of rinsing, solenoid valve A29 and solenoid valve C34 are opened,
Since the solenoid valve B30 is closed, rinsing water is always supplied from the lower part of the inner tub 2, as in the case of washing, and dirty washing water is supplied from the multiple overflow ports 39 provided at the upper part of the inner tub 2. It is effectively discharged to the outside of the inner tank, and is discharged to the outside of the washing machine via the drain port 16, the drain hose 17, and the drain outlet A18.

This state is shown in FIG.

When draining, the solenoid valve A29 and the solenoid valve C34 are closed and the solenoid valve B30 is opened, so the water in the inner tank 2 is discharged to the outside of the washing machine via the drain hose B28 and the drain outlet 31, but the water is not stored. Water remains in the tank 26.

This state is shown in FIG. If dehydration is started in the rinsing state, the weight of the entire vibration system including the water storage tank 26 increases by the amount of water remaining in the water storage tank 26, so the vibration during dehydration becomes sufficiently small.

Also, when the dehydration is finished, solenoid valve A29 and solenoid valve B30 are closed.
is opened and the water in the water storage tank 26 is discharged to the outside of the washing machine from the drain outlet B31, so there is no fear that the water in the water storage tank will freeze or rot.

As described above, the single-type dehydrating washing machine of the present invention stores water in the water storage tank provided in the outer tank during dewatering, increasing the mass of the entire vibration system, so the vibrations caused by unbalanced fabrics are sufficiently small. In addition to being able to hold it down, there is no water in the water storage tank under normal conditions, so it does not impair operability during transportation, etc.

If water is supplied from the lower part of the inner tank through the water storage tank and drained from the upper part as in the embodiment, effective rinsing can be performed and it is sufficiently valuable from the viewpoint of saving water.
