The present invention relates to a filter for washing water of a washing machine, which is returned to the washing water discharged from the reservoir and used again as washing water. Particularly, the present invention relates to a first filter and a third filtering net including a filtration protrusion, a first filtration network, and a second filtration network. The present invention relates to a filter of a shower washer which is configured to sufficiently filter impurities from washing water returned.

Commercially available washing machines may be roughly classified into vortex washing machines, agitated washing machines and drum washing machines according to their washing methods.

In the washing machine, when a washing rod called an agitator, which is erected in the center of the washing tank, rotates regularly, the stirring blade formed on the side of the washing rod forms a stream of water, which causes the laundry to rub against the laundry rod and the wall of the washing tank. This is how it is washed.

These washing machines are less damaging to the fabric than the vortex washing machine, the laundry is not tangled well, the washing capacity is large, but the power consumption is not only high but also suitable for washing bulky laundry due to the laundry rod formed in the center of the washing tank Not

Vortex type washing machine is one of the most widely used method of rotating the laundry by rotating the pulsator is rotatably mounted on the lower end of the washing tank to generate a swirl-like water flow.

In addition, the drum washing machine horizontally mounts a cylindrical drum having a plurality of water outlets in the water tank, and rotates it to lift the laundry to an upper space in the drum by a protrusion in the drum, and then drop downward by gravity. It is designed to be washed while washing, and is suitable for large-capacity washing.

In particular, the washing machine for home use is widely used for washing the vortex type washing machine by rotating the pulsator to form a water flow, which will be described in more detail as a tank type washing machine in one embodiment.

As shown in FIG. 1, the one-type washing machine mounts the washing tank 2 having a plurality of water outlets in the side wall in one reservoir 1 for storing the washing water, and the water flow at the bottom of the washing tank 2. By rotating the pulsator (3) to form a concentric with the washing tank (2) to have a concentric axis and rotates it using an electric motor (4) between the laundry and the laundry, between the laundry and the inner wall of the laundry tank (2) or It is configured to wash by causing friction between the laundry and the pulsator (3), and only the pulsator (3) is left inverted-rest-right inverted during the washing stroke, and the washing tank (2) and pulsator (3) are dehydrated when dewatering. It rotates in one direction and exerts strong centrifugal force on the laundry so that the wash water soaked in the laundry is discharged. The laundry water discharged from the laundry as described above is discharged to the outside of the washing machine in the water tank 1. The drain pump 5, a drain hose (6) for discharging the washing water discharged from the drain pump (5) to the outside of the washing machine, a drain pipe for connecting the drain port (7) and the drain pump (5) of the bottom of the reservoir (1) ( 8) One side end is connected to the upper portion of the reservoir (1) and the other end of the washing water stored in the reservoir (1) by the drainage structure consisting of an overflow tube (9) connected to the outside of the washing machine is drain (7)-drain pipe ( 8)-Drainage pump (5)-Drainage hose (6) is discharged to the outside of the washing machine and the washing water overflowed to the top of the reservoir (1) is discharged directly to the outside of the washing machine through the overflow pipe (9).

When performing cold water washing using the washing machine configured as described above, since the detergent contained in the washing water is not sufficiently dissolved, a sufficient washing effect cannot be exerted, so that the user may not only waste more detergent by putting more detergent, but also dissolve the detergent sufficiently. And it is discharged in the undecomposed state, causing water pollution.

In addition, the water flow formed by the pulsator 3 has a problem that the laundry is twisted or entangled in a swirling vortex that rises along the wall surface of the washing tank 2 and descends to the center of the washing tank 2.

It was developed in order to solve the above disadvantages, and the washing water containing the detergent is returned to the top of the washing tank 2 and sprayed, so that not only dissolves the detergent contained in the washing water sufficiently, but the sprayed washing water impacts the vortex It is possible to form a random flow by adding a shock as well as the impact on the laundry to circulate the washing water having a washing effect of tapping the washing machine which is shown in Figure 1, drain pump 5 of the conventional washing machine After connecting the return hose (10) to the filter case (11) connected to the middle of the return hose (10) and the filter (12) built-in to filter the dirt from the returned washing water It is comprised so that it may inject by the injector 13 of the upper end of the reservoir 1.

As shown in FIG. 2, the filter 12 has a filter plate 11 having a filter insertion hole 18, an inlet port 16 and an outlet port 17, and a flat plate shape having a plurality of water passages 19 formed therein. Flat filter 14, semi-circular cylindrical curved filter 15, also formed with a plurality of water passages 19 and a fixed handle 20 for mounting the filter 12 to the filter case 11 to the drain pump Washing water discharged from (5) and introduced into the filter case 11 through the water inlet 16 passes through the water outlet 19 of the flat plate filter 14, and then again the water outlet of the curved filter 15 19 is passed through the return hose (10) to the injector (13) of the upper end of the reservoir in the filtered state.

However, since the double filter does not sufficiently filter the dirt from the washing water, the returned washing water has a problem of contaminating the laundry again.

Therefore, the present invention aims to provide a quadruple filter which can be filtered in four stages so as to sufficiently filter the dirt from the washing water returned to the reservoir by the drainage pump. .
