Accordingly, when the lower check valve 116 and the upper check valve 128 are opened, the washing water flows into the lower side inlet 112 and the upper side inlet 124, respectively.

The wash water introduced into the lower side inlet 112 is filtered with foreign matter through the lower mesh 118. Some of the washing water filtered with foreign matter is discharged into the washing tank through the lower front discharge part 114.

On the other hand, after the washing tank 6 is directed to the inner wall of the washing tank 6 by the centrifugal force during the high speed rotation, the washing tank 6 rises above the washing tank 6. Such a stream of wash water is also called a wash stream, a circulating stream, or an alpha stream. Hereinafter, it is called alpha stream.

When the alpha stream is generated, the wash water and the foreign matter inside the lower filter 110 are moved toward the upper filter 120 through the communication unit 122. At this time, since the width of the communication portion 122 is narrower than other portions, the flow rate of the washing water is increased, and the washing water and the foreign matter are easily raised.

Foreign substances introduced into the upper filter 120 through the communication unit 122 are filtered by the upper mesh 126, and the washing water filtered by the foreign substances is washed through the upper front discharge unit 125. 6) is discharged into the interior.

The foreign matter filtered by the upper mesh 126 is collected in the collecting space 123. The upper filter 120 is formed to protrude forward, thereby forming the collecting space 123, the upper filter 120 serves to collect as well as filter out foreign matter.

Therefore, the foreign matter is filtered inside the lower filter 110, the filtered foreign matter and some of the wash water may be moved to the upper filter 120 side and collected in the upper filter 120.
