PROBLEM TO BE SOLVED: To achieve the alternative use of the circulation of the washing solution and the supply of bath water by switching the direction of rotating the impeller with a single pump. SOLUTION: The single pump 24 is provided and feeds the water by the forward rotation of the impeller of the pump 24 to enable the supply of the bath water to a water tub 7 through a bath water supply port 26a, a connection hose 26, the pump 24, a connection hose 23 and a connection hose 21. On the other hand, a swing valve to be released by the flow generated and a check valve to be closed thereby in the feeding operation made by the reverse rotation of the impeller are arranged to enable the circulation of the washing solution with the introduction thereof into the water tub 7 again through the connection hose 21, the connection hose 23, the pump 24 and the connection hose 25.
