Washing machine

A washing machine comprising:

• a cylindrical washing/dehydrating tank with its diameter gradually increasing from its bottom to its upper portion, having a bottom fixed to a cylindrical revolving journal arranged as a communicating pipe communicating to said tank;
• an annular drainage pipe co-axially arranged with said tank at an upper periphery of said washing/dehydrating tank;
• loosners for loosening the washing attached to the inner wall of said tank so as to be pushed toward the center of said washing/dehydrating tank;
• a pushing means for pushing said loosners toward the center of said washing/dehydrating tank;
• a dehumidifier;
• an annular opening formed on the inner wall portion of said annular drainage pipe;
• a plurality of drainage openings formed on said washing/dehydrating tank so as to face against said annular opening;
• a three-way branched pipe capable of forming an air supply passage for leading dried air from said dehumidifier to said washing/dehydrating tank, a drainage passage for discharging washing water from said washing/dehydrating tank to the outside or a closed passage for stopping washing water flowing out of said washing/dehydrating tank by diverting a three-way valve, co-axially and revolvingly connected to the lower portion of said cylindrical revolving journal;
• a side pipe arranged between said annular drainage pipe and said three-way branched pipe for circulating overflowed washing water from said washing/dehydrating tank to said annular drainage pipe via said three-way branched pipe to washing/dehydrating tank or for discharging washing water to the outside by a pump;
• and
• a demountable filter arranged in said side pipe.
