PURPOSE:To enable a starting/stopping of a bubble bath operation to be carried out during feeding of hot water to a bath and further facilitate a feeding of a specified amount of h9t water by a method wherein an amount-of-water sensor is placed within a bath hot water feeding passage, air is sucked by an ejector, and an additional heating of a bath is carried out under an arrangement of a by-passing passage. CONSTITUTION:As an amont-of-water of hot water is set by a remote operating part 62 and a hot water feeding switch is turned on, a controller 61 may open valve V2 in a hot water feeding passage 52, hot water of predetermined temperature is fed from a heat exchanger 35 into a hopper 51, a valve V3 is opened with a signal of a water level sensor S3, hot water is fed to a bath tub 20 with a pump P. As an amount of feeding hot water accumulated by an amount-of-water sensor S1 reaches a predetermined amount, the feeding of hot water is terminated. In this case, if a bubble bath operating switch is ON, a valve V4 is opened, air is fed to an ejector 33 and then bubbles are injected within a bath tub 20. When an additional heating switch is turned ON, a valve V1 in the bypassing passage 34 is opened, the bath tub water is flowed through the circulation passage 32 under an operation of a pump P and heated by a heat exchanger 35 and then circulated. In this way, the bubble bath operation can be carried out during feeding of hot water, a feeding of predetermined amount of hot water can be performed and then a mild additional heating can be carried out. |
