Opening the hot water supply valve 15 at step 153, it stores the water supplied from the water heater 7 side cleaning nozzle 48 and the return branch pipe water injection to the tank 5 water water Q 1 in the tank 5 from the 30 side. next,
The hot water supply valve 41 is closed, and the circulation pump 35 is started. As a result, the water stored in the tank 5 passes through the cleaning liquid circulation circuit, is vigorously jetted from the cleaning nozzle 48 to the inner wall surface of the bathtub by the ejection pressure of the circulation pump 35, and the detergent liquid adhering to the inner wall surface of the bathtub and its The dirt components removed by the detergent solution are washed away. The water injection from the washing nozzle 48 stops the circulating pump 35 when one hour has elapsed T, discharging the dirty water by opening the drain valve 12 from the drain pipe 4. Water in the tank 5 when the water discharge valve 12 has elapsed T 2 hours open is determined to have been completely discharged, close the drain valve 12. Then, an operation of storing water in the tank 5 again, an operation of injecting the stored water from the cleaning nozzle 48, and a series of operations from Steps 153 to 161 of discharging dirty water from the tank 5 are performed N times (N is 1 or more).

きる。According to this embodiment, when the detergent liquid adhering to the inner wall surface of the bathtub is dropped after washing the bathtub with the detergent liquid, the water stored in the tank 5 is forcibly circulated by the circulation pump 35 and the cleaning nozzle 48, Because it is sent to the 49, even when spraying water from multiple washing nozzles 48, 49, water can be sprayed with a strong pump pressure by the circulation pump 35, so it adheres to the inner surface of the bathtub. This makes it possible to cleanly wash off the detergent solution. The cleaning of the detergent solution by the water jet may be performed only once, but the detergent solution can be completely dropped by repeating the operation several times.

えば、浴槽蓋50に設けることができる。In the above embodiment, three cleaning nozzles 48 are used.
And three washing nozzles 49 are provided on the opposite side wall of the bathtub, but the number of washing nozzles 48, 49 can be any number equal to or more than one. In the present embodiment, since water is jetted from the cleaning nozzles 48 and 49 by the pump pressure of the circulation pump 35, a strong jet pressure can be obtained even when the number of the cleaning nozzles 48 and 49 is plural, and the inner wall surface of the bathtub can be obtained. Detergent liquid adhering to the surface can be removed cleanly. In the case where the number of cleaning nozzles 48 and 49 becomes very large and the ejection pressure is insufficient with one circulation pump 35, the problem can be solved by providing a plurality of circulation pumps. Usually, in this type of system, a self-contained pump is used as a circulating pump in order to smoothly start the pump. However, as is well known, it is difficult to increase the capacity of the self-contained pump. When the number of pumps 48 and 49 becomes very large and it is necessary to increase the number of pumps, the circulating pump 35 is replaced with a large-capacity non-self-contained pump.
When the self-contained pump 61 is provided as shown by the broken line, it is convenient to achieve both smooth start of the pump and increase in capacity. Even when the washing nozzles 48 and 49 are formed one by one, the water jetted from the washing nozzles 48 and 49 is jetted by the pump pressure. The force is increased, and the cleaning effect of the detergent liquid becomes more remarkable as compared with the conventional example. Further, the cleaning nozzles 48 and 49 can be provided at a location other than the side wall of the bathtub, for example, at the bathtub lid 50.
