The case body a is a bathtub installation type in which the upper case 1 is placed on the bathtub rim 2a of the bathtub 2, and the lower case 3 is submerged in the bathtub 2 and attached to the inner surface of the bathtub 2, so it does not take up much space. It can be easily installed by using the space above the bathtub edge 2a.

2 Since the case body a itself does not have a conventional heater, it is compact and can be installed without taking up much space. Since the shape of the case body a is shaped like a mold when viewed from the side, the lower case 3 is installed tightly against the inner wall of the bathtub and does not get in the way.

3. Since there is no heater, costs will be reduced.

4. Since it is a forced filtration type in which a filter material 4 and a sterilizer 5 are provided in the lower case 3 to filter the hot water in the bathtub 2, excellent purification is achieved.

5. Since the heavy circulation pump 6 is provided in the upper case 1 placed on the bathtub edge 2a, the weight of the circulation pump 6 is supported on the bathtub edge 2a, so the case body a cannot be dislodged by the weight of the circulation pump 6. This means that it can be installed stably.

6. An outside air introduction pipe 22 is provided in the upper case 1, and the electric cord 21 of the circulation pump 6 is connected to this outside air introduction pipe 22.
Since the inside of the upper case 1 is passed through and pulled out to the outside of the case body a, the waterproofness inside the upper case 1 is good, and the circulation pump 6 inside the upper case 1 is cooled by the outside air from the outside air introduction pipe 22.
overheating of the drive part is prevented.
