Abstract

PURPOSE:To prevent only detergent from being previously fed to a detergent guide member by starting to rotate the detergent guide member to a guide position direction and feeding detergent from a detergent feeding part to the detergent guide member after prescribed time elapses when the water feed valve of a water feeding means is opened. CONSTITUTION:Upon the start of charging detergent, the rotation of a detergent guide member 30 located at a stand-by position is started to the direction of a guide position. After the water feed valve of a water feed means 29, detergent is supplied to the detergent guide member 30 from a detergent feed part with the elapse of prescribed time. When the charging of the detergent is started, therefore, the rotation of the detergent guide member 30 begins and the water feed valve is opened before the feed of the detergent from the detergent feed part 15. As a result, although some time is required until the detergent guide member situated at the stand-by position is rotated to the guide position, the detergent can be supplied to the detergent guide member after it comes to a normal position. Even when a user opens a faucet with delay, the previous feed of only the detergent to the detergent guide member can be avoided.
