DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to a pipe diagram of FIG. 1 and a perspective view of FIG.

Reference numeral 1 denotes a bath tub containing hot water 2, and an overflow recovery groove 3 for collecting the overflowing hot water 2 is provided around the outer periphery of the bath tub 1.

Reference numeral 4 denotes a purifying device. The purifying device 4 includes a filtration tank 5 filled with a filter medium for filtering dirt, a heating device 6 for keeping heat, and an activated stone for activating treatment. A filled activated stone tank 8 and the like are provided, and an ozone generator and the like for sterilization are also provided, although not shown.

Reference numeral 9 denotes a water suction pipe for sucking up the hot water 2 in the bathtub 1 and sending the hot water 2 to the cleaning device 4, and reference numeral 10 denotes a device for discharging the hot water which has been subjected to the cleaning process in the cleaning device 4 to the bathtub 1 again. The hot water pipe 9 and the hot water pipe 10 are housed in a hot water unit 16 and attached to the inner wall of the bathtub 1 as shown in FIG.

A pre-filter is attached to the inlet of the hot water pipe 9 and a jet nozzle 17 is attached to the outlet of the hot water pipe 10. Large suspended matters are removed by the pre-filter and then sent to the cleaning device 4. At the same time, the hot water after the cleaning treatment is jetted from the jet nozzle 17 as a jet stream.

Numeral 12 designates an overflow reservoir provided adjacent to the bathtub 1. The overflow reservoir 12 is connected to the overflow recovery groove 3 provided on the outer periphery of the bathtub 1 by a connecting pipe 11. Further, a water level detector 13 for detecting that a predetermined amount of overflowing water has been collected is provided.

A hot water pipe 14 for feeding the hot water recovered from the hot water storage tank 12 to the cleaning device 4 is extended, and the hot water pipe 14 is provided with hot water in the bathtub 1. 2 is connected to a hot water pipe 9 for sending the cleaner 2 to the cleaning device 4 via a three-way switching valve 15.
