The protective tube 32 does not easily break because the vibration of 30 does not occur.

Also, by inclining the inner peripheral surface of the upper flange 34,
Since the upper O-ring 35 is easily disengaged when the stopper 28 is removed and the protective tube 32 is pulled out, the protective tube 32 can be easily pulled out without being damaged. Further, by making the lower flange 36 have the same structure, the lower cap 29 can be easily removed.

The opening 28a provided in the stopper 28 is used for the sterilization lamp 3
This is for inserting and removing 3 while the protection tube 32 is still attached. Also, the convex portion 28b provided on the stopper 28,
When the bath water flows in between the outer pipe 25 and the protection pipe 32, water pressure is applied to the protection pipe 32 and the protection pipe 32 is prevented from protruding upward.

Next, operation control of the circulation pump 18 and lighting control of the sterilization lamp will be described with reference to FIG.

The bath water purification heat retention apparatus described in this embodiment keeps the bath water temperature in the bathtub constant at all times, and raises it to the set temperature when the bath time preset by the controller 23 shown in FIG. 1 comes. It is to heat.

First, FIG. 6A shows that the controller 23 sets the bathing time from 11:00 to 12:00.

Next, FIG. 6B shows the operating state of the circulation pump 18, showing that the circulation pump 18 is operated from 11:00 to 12:00 set as the bathing time, and the others are operated periodically, for example, for 10 minutes per hour. There is.

FIG. 6C shows the time when the sterilization lamp 31 is turned on, and shows that the sterilization lamp 31 is turned on several times a day.

As described above, by always operating the circulation pump 18 when the sterilization lamp 31 is turned on, sterilization can be performed efficiently.

 The above control is performed by the control device 24.

EFFECTS OF THE INVENTION As is clear from the above description, the present invention is excellent in terms of safety and life because it uses a sterilizing lamp as a sterilizing apparatus, and a sterilizing tank having this sterilizing lamp is used as a circulation pump and a filtration tank. Even if the lamp or the like is damaged, it will not be stopped by the filtration tank and will not flow into the bathtub and will not enter the circulation pump. Therefore, a bather will not be injured by a broken piece such as a lamp, and the circulation pump will not be damaged.

Further, according to the present invention, the protective tube for inserting the sterilizing lamp is fixed at the lower portion by the protective tube receiver and at the upper portion by the O-ring and the stopper, so that the protective tube is not vibrated or deformed by water pressure and damaged. It is possible to prevent it, and it is possible to prevent the protection tube from protruding from the outer tube due to water pressure. Further, since the O-ring is in contact with the inner peripheral surface that gradually expands toward the open end of the outer tube, maintenance, especially removal of the protection tube. Can be done easily.

Further, the present invention, in the bath water purification heat retention unit,
A filter tank is provided near the one side having the bath water intake port and the bath water return port, a filter tank is provided near the other side having the refrigerant inlet port and the refrigerant outlet port, and a circulation pump and a filter are provided between the filter tank and the filter tank.
