FAUCET
Document Type and Number:
Japanese Patent JP3546916
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent massive discharge when a valve is switched by providing a constant flow valve in a water discharge section where multiple water supply channels provided with a water supply valve that is opened or closed alternately merge with each other.
SOLUTION: Electromagnetic valves 104, 105 are provided in a hot water supply channel 111 and a cold water supply channel, respectively, a water discharge portion 113 where the hot water and cold water supply channels are merged with each other, is provided on the downstream side, and a constant flow valve 120 is provided in the water discharge portion 113. When the valves 104, 105 are switched from one to the other, the supply of hot water begins before the supply of cold water has not finished yet for example. However, the valve 120 regulates the total amount of water discharged and thereby prevents the amount of water discharged from exceeding a fixed level. And then, the valves 104, 105 are to be turned on instead, energization prohibition time of about 1 second is set during a shift from the off condition to the on condition. As a result, as discharge on the hot water side begins after water is cut off on the cold water side, there is no possibility that both cold water and hot water will be discharged at the same time, thereby preventing water from being discharged in large quantities and then surprising the user.
