In general, a washing machine is a device that exfoliates contaminants by applying energy such as impact to laundry, and may be divided into a pulsator washing machine, a drum washing machine, and an agitator washing machine according to a method of applying energy to laundry.

In other words, the laundry is impacted by a pulsator or agitator, or the laundry is dropped by rotating the drum to impact the laundry. And the action of the detergent is added to this is done washing. That is, the above washing machine is a method of washing laundry by giving a shock to the laundry in a mechanical manner.

However, the washing machine as described above mainly washes using mechanical energy such as pulsator and agitator, and thus it is difficult to avoid twisting or damaging the laundry because a rotational force of a predetermined speed or more is required to satisfy the required degree of washing.

In addition, the pulsator washing machine as described above, since the washing machine operates in a state in which water is filled in the inner tank and the outer tank, the amount of washing water used for washing and the amount of detergent are increased, and the overall water supply and drainage time is not directly increased due to the increase in the drainage time. There was a problem that the washing time increases.

Therefore, in order to solve this problem, a washing water circulation type washing machine has been proposed. That is, the washing water is circulated to the inner tank at the time of washing or rinsing, and the circulated washing water is sprayed to the laundry of the inner tank. In this manner, since only a small amount of washing water may be supplied to the inner tank and the outer tank, the above-described problems may be solved to some extent.

Referring to Figure 2 when referring to as follows.

Figure 2 is a schematic cross-sectional view showing a drainage for a washing machine according to the prior art, the storage tank 110 for storing the washing water is installed inside the washing machine case 100, a plurality of inside the storage tank 110 A washing tank 120 having a through hole 122 is rotatably installed, and a pulsator 130 is rotatably installed inside the washing tank 120.

In addition, the washing tank 120 and the pulsator 130 are rotated by the driving means 140 installed on the bottom surface of the reservoir 110.

On the other hand, the bottom of the reservoir 110 is connected to the drain pipe 150 for discharging the wash water to the outside of the washing machine, a drain valve (not shown) is installed at a predetermined position of the drain pipe 150.

Subsequently, a circulation pipe 160 for circulating the washing water to the washing tank 120 is branched at a predetermined position of the drain pipe 150, and a pump 170 for pumping the washing water at a predetermined position of the circulation pipe 160. Is installed.

Subsequently, a filter 180 for filtering foreign matter such as hair and the like is installed in the drain pipe 150 where the circulation pipe 160 is branched, and a dust collecting tube 190 is formed at the lower end of the filter 180.

The operation of the conventional washing machine configured as described above may be divided into a washing stroke, a rinsing stroke, and a dehydrating stroke. Each of the modes is sequentially performed to perform washing.

Referring to the laundry administration, when the laundry is put into the washing tank 120 and the washing machine is operated, the washing water is supplied to the washing tank 120, and the washing water fills the washing tank 120 and the storage tank 110 to a predetermined level.

When the washing water is filled in the washing tank 120 and the water storage tank 110 and the water supply is completed, the pulsator 130 performs the forward and reverse rotation to wash the laundry. At this time, the pump 170 is also driven to wash water passes through the filter 180, the wash water passing through the filter 180 is discharged back to the washing tank 120 while the foreign matter is filtered.

After the washing process is underway for a certain time, the drain valve is opened to discharge the contaminated washing water to the outside. After supplying clean wash water to the washing tank 120 again, the pulsator 130 is rotated to perform a rinsing stroke. At this time, the pump 170 is driven so that the wash water passes through the filter 180, and the wash water passing through the filter 180 is discharged back to the washing tank 120 while the foreign matter is filtered out.

In addition, in the dehydration stroke, the washing tank 120 and the pulsator 130 rotate together at high speed in one direction. Therefore, the washing water of the washing tank 120 by the centrifugal force is discharged to the reservoir 110 through the through-hole 122. At this time, since the pump 170 is stopped and the drain valve is open, the wash water discharged to the water tank 110 is discharged to the outside of the washing machine through the drain valve.

However, in the conventional washing machine as described above, the filter 180 installed in the drain pipe 150 and the lower end of the circulation pipe 160 branched to the drain pipe 150 are located on the same line, so that the filter 180 in the washing rinsing or rinsing cycle. Some lint, soil, and the like filtered through the drain pipe 150 is not discharged to the pump 170 is introduced into the pump 170, causing the failure of the pump 170, as well as foreign matter such as lint, soil Although the filter 180 does not pass through the filter 180 completely, the filter 180 remains in the filter 180 as it is, and after use of the washing machine for a predetermined time, the filtration performance of the filter 180 is deteriorated, and the user is attached to the filter 180. There was an uncomfortable problem of periodically removing the foreign matter.
