Description

[Detailed description of the invention] This invention relates to a water injection device for a two-tank dehydrating washing machine that is equipped with a washing tub and a dehydrating tank. This makes it possible to pour water into the washing tank or to flush out the foam remaining after draining the washing tub.

Conventionally, in order to shorten the time and labor required for washing, rinsing, and spin-drying, various two-tank dehydrating washing machines have been proposed, which store water in a dehydrating tank and repeat the cycle of stirring, draining, and draining. It has been put into practical use in the department.

However, the water injection device of these washing machines generally used a three-way cock to inject water from the water supply hose into either the washing tub or the spin tub.

In this type of washing machine, the laundry that has been washed in the washing tub is transferred to the spin-drying tub, where it is rinsed and dehydrated.Water is then poured into the washing tub to wash the next laundry, and water is drained into the washing tub. It is not possible to pour water to wash away the remaining suds, and in order to pour water into the washing tub, you have to interrupt the rinsing or spin-drying process, or wait until it is finished, making it inconvenient to use. Met.

The present invention eliminates such inconveniences, and will be described below with reference to the accompanying drawings.

Inside the washing machine body 1, there are a washing tub 3 and a washing tub 1 equipped with rotary blades 2 at the bottom. A dehydration tank 16 integrated with this is fixed.

A panel 8 containing a water supply valve 4, a washing timer 5, a dehydration program timer 6, a pressure sensitive switch 7, etc. is provided on the upper part of the main body 1.

A washing motor 9 and a dewatering motor 10 are provided at the bottom of the main body 1, and the rotation of the washing motor 9 is transmitted to the rotary blade 2 by a pulley 11 and a belt 12.

A drain port 13 is provided at the bottom of the washing tub 3, and a filter 14 is attached to the drain port 13.

A drain valve 15 is provided below the drain port 13.

A dehydrating basket 18 having a large number of holes 17 is rotatably provided in the center of the dehydrating tank 16, and is rotated by a dehydrating motor 10.

At the top of the dehydration tank 16 is a dehydration tank cover 1 with a hole in the center.
9 is provided, and a water injection nozzle 20 is fixed to the lower side of this dehydration tank cover 19.

The outlet 21 of the water injection nozzle 20 is oriented such that water enters the upper part of the dewatering basket 18, and a hose 23 is connected to the inlet vibrator 22.

The other end of the hose 23 is connected to one outlet 24 of the water supply valve 4.

An air trap 26 and an electromagnetic drain valve 27 are provided below the drain port 25 of the dewatering tank 16.

The air trap 26 and the pressure reduction switch 7 are connected through an air hose 28.

A dehydration cap 29 is removably provided on the upper part of the dehydration basket 18 to prevent the water from coming out, and this dehydration cap 29 has several holes 3 through which the water discharged from the water injection nozzle 20 passes.
0 is the default.

31 is a shaft of the dehydration basket 1B, 32 is a buffer body equipped with a bearing and a shaft seal, and 33 is a suspension.

34 is a water supply hose, and 35 is a drainage hose.

36 is a switch that energizes the water supply valve 4 when water is poured into the washing tub 3.

Next, the structure of the water supply valve 4 will be explained with reference to FIG.

A water supply hose 34 is connected to the inlet 37 of the water supply valve 4 .

Below the inlet 37, the flow path branches into a flow path 38 to the washing tub and a flow path 39 to the dehydration tank, and each flow path is provided with a valve seat 40, 41.
An outlet 42.2 is provided below the valve seat 40.41.
There are 4.

The outlet 42 to the washing tub opens above a part of the corner of the washing tub 3, and the outlet 24 to the dehydration tub is connected to a hose 23 whose other end is connected to a water injection nozzle 20 for the dehydration basket.

Diaphragms 43, 44 are pressed against the valve seats 4G, 41 by plungers 45, 46 and presser plates 47, 48.

A compression spring 51.52 is connected between the upper end of the plunger 45.46 and the upper part of the cylinder 49.50 covering the outside thereof.
Contains.

The outside of the cylinder 49 is energized by the switch 36,
A solenoid 53 is installed which is shut off.

Further, a solenoid 54 is attached to the outside of the cylinder 50 and is energized and cut off by the dehydration program timer 6.

One or two holes 55, 56 are provided in the portions of the diaphragms 43, 44 outside the valve seats 40, 41.

In the above configuration, the clothes that have been washed in the washing tub 3 are transferred to the dehydration basket 18, and the deicing program timer 6 is activated.
When turned on, the drain electromagnetic valve 27 closes and at the same time the solenoid 54 of the water supply valve is energized to inject water into the dewatering tank 16 from the water injection nozzle 20.

When the water in the dehydration tank 16 reaches a specified level, the pressure sensitive switch 7 detects this and the water supply valve 4 closes, at the same time the dehydration motor 10 is activated.
The dehydration basket 18 rotates by applying electricity to perform the rinsing process.

At the same time as the dewatering motor 10 stops after a set time, the drain solenoid valve 27 opens and draining starts.

After the set time, the dehydration motor 10 rotates again to perform dehydration.

Repeat this cycle several times and rinse to complete the dehydration.

When you want to add water to the washing tub 3 during this rinsing and spin-drying to perform the next washing, or to pour water into the washing tub 3 to wash away the bubbles that have adhered to the inner surface of the washing tub 3, turn on the switch 36 and turn on the solenoid. 53 and plunger 45
is raised against the spring 51, and the diaphragm 4
3 from the valve seat 40, the washing tub 3 is opened from the outlet 42.
water is poured inside.

As described above, according to the present invention, the dehydration program timer allows rinsing in the dehydration tank, and while performing the dehydration process, water can be optionally poured into the washing tub by operating only one independent switch, and washing can be continued. It is also possible to wash away foam adhering to the inner surface of the washing tub, which greatly improves usability.

Moreover, since it is operated by a switch, it also has the effect of being easy to operate.
