<p>PURPOSE:To prevent a high water pressure of the outside water supply from suddenly being applied to a circulation pump of a bath circulation passage by a method wherein a automatic water feeding passage is connected to a going-out pipe of a bath circulation passage by a second water passage switching valve, and from the automatic water feeding passage at this side of the second water passage switching valve, a by-pass is connected to a water feeding passage for washing machine by a by-pass opening/closing valve. CONSTITUTION:An automatic water feeding passage 30 is connected to a going-out pipe 41 of a bath circulation passage 40 by a water passage switching valve 62, and from the automatic water feeding passage 30 at this side of the second water passage switching valve 62, a by-pass 80 is connected to a water feeding passage for washing machine 70 by a by-pass opening/closing valve 63. When hot water or cold water is automatically fed to a washing machine 2 from the automatic water feeding passage 30, by a first water passage switching valve 61, a return pipe 42 at the upstream side of the first water passage switching valve 61 is connected to the water feeding passage for washing machine 70, and by the second water passage switching valve 62, the going-out tubes 41 at the upstream side and downstream side of the second water passage switching valve 62 are passage-connected to each other, and a by-pass opening valve 63 is opened.</p> |
