The present invention relates to a washing water purifying apparatus of a washing machine, and more particularly, to a washing water circulating device of a washing machine that can effectively filter the dirt and the like during washing while dissolving the detergent completely.

In general, the automatic washing machine puts laundry in a washing tank and sequentially washes the laundry by sequentially setting a program for supplying water, washing, rinsing, draining, and dehydrating.

In addition, the washing or rinsing process is performed by washing and rinsing with water and detergent put into the washing tank, draining it through a drainage device, and then supplying clean water to the washing tank to proceed to the next washing stroke. However, in the related art, since detergent and washing water mixed in the detergent drawer are simply dropped from the water inlet 1 into the washing tank 2 as in the first drawing, the detergent may not be completely dissolved in the washing water, and one side of the washing tank 2 may also be used. The wash water supplied by the filter water flow guide (3) installed in the filter passes through the nylon filter (4) to filter dirts from washing and rinsing, but the filter (4) is not only able to filter all the wash water, but also the laundry. In addition, there is a problem that must be frequently exchanged because it is damaged by friction with the wash water of the wash water.

US 5 designates the reservoir.

The object of the present invention is to provide a washing water circulation system for a washing machine that can effectively filter the dirt from washing while circulating the washing water using a pump to completely dissolve the detergent to solve the above problems.

In order to achieve the above object, the present invention provides a drain for draining the wash water to the bottom part of the washing tank, and a washing water circulation path having a filter at the washing water supply end and supplying the washing water connected to the drain to the washing tank. And a pump installed on the drain port side circulation path, a valve installed between the pump and the wash water supply end, and a drain hose connected to one side of the valve.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the washing water circulator of the washing machine according to the present invention.

2 is a cross-sectional view showing the configuration of the present invention.

The washing machine includes a washing tank 6 and a storage tank 7 inside the main body, and the washing water in the washing tank 6 is provided with a drain 8 for circulation at a predetermined position of the bottom of the storage tank 7 during the washing or rinsing process. .

The drain 8 drains a small amount of washing water during washing and rinsing without affecting the required quantity for washing or rinsing, and the drain 8 provides drained washing water to the washing tank 6. The circulation passage 9 is connected to one end of the circulation passage 9, and a washing water supply end 10 is connected to one end of the circulation passage 9, and the washing water supply end 10 is provided with a filter 11 for filtering the washing water. do. In addition, the wash water supply end 10 is preferably integrated with the water inlet of the water supply valve, the filter 11 is formed of a solid material to be detachable to the wash water supply end 10 to shake off the dirt from time to time It is desirable to discard and reuse.

A pump 12 is installed on the drain passage 8 side circulation path 9 by a power source. The pump 12 circulates the drained washing water through the circulation path 9 to the upper part of the washing tank 6. At the same time, it causes friction with the wash water and detergent drained by the impeller of the pump 12 to completely dissolve the detergent. And a valve 13 for changing the water flow between the pump 12 and the wash water supply end 10 is provided, one side of the valve 13 is connected to the drain hose (14). The drain hose 14 may also be used as an existing drain hose, and may also be used when draining to a higher place than the drain hole 8, such as a sink.

The use state is as follows. When the washing water in the washing tank 6 reaches a certain level during washing or rinsing, the water is stopped from the water inlet of the water supply valve, and washing or rinsing proceeds. At this time, when power is applied to the pump 12, the washing water in the washing tank 6 is The detergent is completely dissolved by the pumping action of the pump 12 through the drain hole 8, and is filtered through the circulation passage 9 to the filter 11 installed in the wash water supply end 10, and then supplied again into the washing tank 6. .

At this time, the valve 13 should open the circulation passage 9 and block the drain hose 14. In addition, when draining, the valve 13 blocks the circulation path 9 and opens the drain hose 14 to drain the wash water drained through the drain hole 8 to the drain hose 14 by the pumping action of the pump 12. do.

Therefore, the washing water in the washing tank is washed more cleanly because the washing process or the rinsing process is performed while the detergent is continuously supplied with the completely dissolved detergent while filtering the dirt.

According to the present invention of the above-described configuration, by using the pump to circulate the wash water to provide a washing water circulation device of the washing machine that can effectively filter the dirt during washing while dissolving the detergent completely.

Claims (1)
