PROBLEM TO BE SOLVED: To eliminate generation of abnormal noise due to a check valve in the machine having the check valve in a communication part between water supply equipment and a water tank. SOLUTION: In a washing/drying machine with a check valve 52 mounted to a valve box 53 on a communication part with the water tank of the water supply equipment (hose joint 51), the check valve 52 is continuously provided with the valve element 59 from the mounting part 58 in shape of flap. In the valve element 59, the angleθ<SB>2</SB>of valve element 59 for mounting part 58 before mounting the check valve 52 is less than the angleθ<SB>1</SB>of the valve seat (peripheral edge 55a of the water passing port) of the abutting valve box 53 thereof. When mounting, the check valve 52 is installed at a wider angle of valve element 59 thanθ<SB>2</SB>by the valve seat of valve box 53. By elastic resilience from the status, the valve seat of valve box 53 is continuously pressure-contacted with the valve element 59. By this mechanism, the valve element 59 does not repeatedly hit the valve seat in minute rhythm, even when vibrations in dewatering and wind power in drying increase, and generation of the abnormal noise can be eliminated.
