Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic washing machine, for example,
During the timer cycle, the rinsing water after the final rinsing process is stored using a pump in a water storage tank that is removably attached to the main body, and at the time of the next washing, the stored water is returned to the washing tank by the pump and used as washing water. In addition to being reusable to save water, it is also possible to wash heavily soiled items by hand in the water storage tank.

Conventional automatic washing machines typically automatically discard rinse water after the final rinse cycle during a timer cycle. However, the rinsing water in this final rinsing step has little dirt and can be used as water for the next wash. Therefore, it is possible to install a water tank and store the soot water in this tank.In detail, the pump is operated and the water pump is activated both when draining the water stored in the water tank and when transferring it to the washing tank. Water was discharged through water pipes.

However, with this method, the pump must be operated even when draining water, which consumes a large amount of electricity.Also, if heavily soiled items are washed in the water tank, the dirty liquid will be released as mentioned above. Since the water is drained through the water pipe, the inner wall of the water injection pipe becomes dirty, and when clean rinsing water is stored in the water tank next time, the water passes through the dirty water pipe and becomes dirty.

The present invention eliminates the above-mentioned conventional drawbacks, and embodiments thereof will be described below.

In the figure, 1 is the main body of the washing machine, 2 is the outer tub,
It has a washing tub 3 which can be rotated for dewatering and has stirring blades at the inner bottom, and is suspended and supported within the main body 1 by a vibration-proof support device 4 comprising a spring, a rod, and the like. 5 is a drain pipe for draining washing water and rinsing water from the lower part of the outer tank 2, and a drain valve 6
It is connected to the. Reference numeral 7 denotes an in-machine hose for draining washing water and rinsing water to the outside of the washing machine main body 1, and one end is connected to a drain valve 6, and the other end is connected to a drain port 8 attached to the main body 1.

Reference numeral 9 denotes a water storage tank mechanism main body having a water storage tank 10 formed therein, which is detachably installed in parallel with the main body 1. 11 is a pump, 12 is a manual drain valve,
13 is a drain pipe, which includes a water storage tank 10 and a drain valve 1.
2 are connected. 14 is a three-pronged connecting pipe, each end of which is connected to the drain port 8, the suction side of the pump 11, and a drain pipe 15 connected to the drain valve 12, respectively. 16 is an electromagnetic drain valve, washing tub 3
It is controlled by a program timer (not shown) to close when storing the liquid in the water storage tank 10 and to open during other steps.

Reference numeral 17 denotes a discharge pipe, one end of which is connected to a water injection pipe 18 and the other end connected to the discharge port side of the pump 11, and the water injection pipe 18 is rotatably attached to the discharge pipe 17. 19 is a cam attached to the water injection pipe 18 and rotates as the water injection pipe 18 rotates;
A wire 20 has one end connected to the cam 19 and the other end connected to the manual drain valve 12 via a spring 21.

19a is a groove formed in three places on the cam surface of the cam 19; 22 is a water injection pipe control stop plate fixed to the water storage tank mechanism body 9; one of the grooves 19a of the cam 19 and a protrusion 22a provided on the water injection pipe control stop plate 22; By fitting together, the water injection pipe 18 is connected to A, B,
It is configured to be fixed at three locations C.

23 is a switch, and when the operating part 23a is pressed, the pump 11 is activated and at the same time the drain valve 16 is closed.

Here, the shape of the cam 19 is set so that when the water injection pipe 18 is rotated from the position A to the position B, the operating part 23a of the switch 23 is pushed by the cam surface of the cam 19. 24 is an external hose connected to the drain valve 16.

The operation in the above configuration will be explained.

The drain valve 6 is closed during the washing process and the rinsing process. In the next draining process and dewatering process, the drain valve 16 is opened, and the washing water is drained through the in-machine hose 7, pump 11, drain valve 16, and external hose 24.

When transferring the liquid in the washing tub 3 to the water storage tank, in the case of washing liquid, the drain valve 6 opens and drains during the draining process after the washing process, and in the case of rinsing liquid, the drain valve 6 opens and drains during the final draining process after the final rinse. Valve 16 is closed and pump 11 is activated. The washing liquid and the rinsing liquid reach the pump 11 via the drain valve 6 and the in-machine hose 7, and are further injected into the water storage tank 10 through the discharge pipe 17 and the water injection pipe 18.
In the final dehydration step, water is stored in the water storage tank 10 by the same operation.

Transfer the water in the water storage tank 10 to the washing tub 3,
When using the water for washing again, connect the water injection pipe 18 to A.
The water injection pipe 18 is rotated from the position to the B position so that the opening of the water injection pipe 18 faces the opening of the outer tank 2, and is fixed by fitting the groove 19a of the cam 19 and the water injection pipe control stop plate 22 into the protrusion 22a. Then, the wire 20 fixed to the cam 19 is pulled up, and the drain valve 12 is opened via the spring 21. Further, the cam 19 pushes the operating portion 23a of the switch 23, and the pump 11 operates and the drain valve 16 closes at the same time. Therefore, the water in the water storage tank 10 is drained from the drain pipe 1.
3. The water passes through the drain valve 12 and the drain pipe 15, reaches the pump 11, is further discharged by the pump 11, and is injected into the washing tub 3 of the washing machine main body 1 through the discharge pipe 17 and water injection pipe 18. .

Next, when draining the water in the water storage tank 10,
When the water injection pipe is rotated from the A position to the C position, the drain valve 12 is opened by the wire 20 fixed to the cam 19, and the water in the water storage tank 10 is drained from the drain pipe 1.
3, drain valve 12, drain pipe 15, pump 11,
The water is drained through the drain valve 16 and the external hose 24.

In addition, in the above embodiment, the case where the water storage tank 10 and the main body 1 of the washing machine were separated was explained.
The water storage tank 10 and the main body 1 may be integrated.

As is clear from the above embodiments, according to the present invention, when the washing liquid or rinsing liquid of the washing machine is transferred to the water storage tank, the liquid in the water storage tank is transferred to the washing machine, and the liquid in the water storage tank is drained, The liquid can be moved by simply changing the direction of the outlet of the water pipe, making it possible to reuse the washing liquid and rinsing liquid with a simple operation. In addition, when draining the water in the water storage tank, the dirty liquid does not pass through the water injection pipe, so there is less dirt on the water injection pipe, and when rinsing water is injected, the rinsing water does not get dirty, and the inside of the water storage tank does not get dirty. When draining water from a water storage tank, it is allowed to fall naturally, so there is no need to operate the pump, and power is not wasted; Even if the program is a drain process, the water in the water storage tank can be drained, making it easy to use.
