Claim 1:
2. The device of claim 1, wherein the centrifugation chamber comprises:
a first chamber coupled with the vacuum pump at an upper part of the first chamber such that the first chamber and the vacuum pump communicate with each other, with a spiral vortex guide being provided inside the first chamber;
a second chamber, wherein an upper part of the second chamber is coupled with a vacuum tube, the vacuum tube is coupled with the vacuum suction, a first partition wall is formed between the second chamber and the first chamber, and a first through hole is formed under the first partition wall such that moisture and foreign matter centrifuged in the first chamber are introduced into the second chamber; and
a third chamber coupled with a drainpipe at one side of the third chamber, wherein a second partition wall is formed between the third chamber and the second chamber, and a second through hole is formed under the second partition wall,
wherein a check valve is coupled to the second through hole, and when an operation of the vacuum pump stops, the check valve is opened by a pressure of water filled in the second chamber, so that moisture and foreign matter stored in the second chamber are discharged to the drainpipe.
