Abstract

PURPOSE: To shorten a hot water feeding time by a method wherein a back-flow preventing device having a surrounding air releasing port is disposed in a hot water feeding circuit, the first opening or closing valve is disposed at the downstream side of it, a hot water feeding circuit is connected to a bath circulation circuit between a water level sensor and a pump and then the second opening or closing valve is disposed between the connection part and the water level sensor.
CONSTITUTION: Water from a water supplying pipe 11 passes through a water supplying and heating device 12, a hot water feeding valve 21, a back-flow preventing device 22, the first opening or closing valve 29 and a forward passage 30a under an instruction of hot water feeding of a remote controller 51 and then the water flows into a bath circulation circuit 30. After a predetermined time elapses, the second opening or closing valve 33 is opened and water is also supplied from a back-flow passage 30b. A corresponding amount of water is supplied up to an instructed water level, the hot water feeding valve 21 and the first opening or closing valve 29 are closed and then the supplying of the hot water is stopped. A pump 31 is operated, a water flow is detected by a water flow switch 40, the second opening or closing valve 33 is closed and the water level sensor 34 is lower than the instructed water level, the first opening or closing valve 29 and the hot water feeding valve 21 are opened and then the hot water feeding is started again. At this time, the second opening or closing valve 33 is closed and the back-flow passage 30b are kept to keep the hot water accumulated so as to detect the water level. Upon completion of the control of the hot water feeding, water in the valve chamber 23b and the hopper 2 is recovered to the bath tub B under an operation of the pump 31.
