<P>PROBLEM TO BE SOLVED: To provide a device for washing bathroom member capable of surely mixing a predetermined amount of a detergent into washing water by supplying the washing water into which air is not mixed to washing piping even when supplying the washing water to the washing piping through circulation piping connected to a bathtub. <P>SOLUTION: The washing piping is branched by a three-way switching valve interposed in return piping of the circulation piping. By turning a washing switch ON, washing preprocessing is performed first. The flow rate adjusting valve of a hot water supply path is turned to a large flow rate Q1 and a hot water pouring solenoid valve is opened (S1, S2). The hot water pouring of the large flow rate Q1 is continued to the circulation piping for the time t1, residual water into which the air is possibly mixed inside the internal path of the return side, the outgoing side and a bath heat exchanger is driven out to the bathtub, and the state of being filled with the poured hot water is attained. Then, the three-way switching valve and an opening/closing switching valve are switched to start bathtub washing processing (S3, S4), and the detergent is mixed after the lapse of the predetermined time. <P>COPYRIGHT: (C)2011,JPO&INPIT |
