There are the following two fixing methods for fixing the filtering device 1 in the bath 10.

As shown in FIG. 5, when the filtration device 1 is fixed to the flat portion of the inner wall 11 of the bath 10, the flat portion 2 a of the side surface of the tubular body 20 of the filtration device main body 2 having a substantially D-shaped cross section. When the fixing member 6 is positioned on the inner wall 11 side along the elongated hole 60 of the support member 61 in a state where the fixing member 6 is in contact with the inner wall 11 of the bath tank 10, and is fixed, the filtering device 1 is securely attached to the bath 11. Since the curved surface portion 2b of the tubular body 20 faces the front, the running water resistance against hot water is small, and it is unlikely to be an obstacle when taking a bath. This is suitable when the hot water jet nozzle 8 and the like are provided in parallel at one end of the bath 10 as shown in FIG.

Further, when it is not possible to secure a fixing space for the filtration device 1 at one end of the bathtub 10 or when it is difficult to secure a sufficient bathing space in the longitudinal direction of the bathtub 10, as shown in FIG. The filtering device main body 2 of the device 1 is turned upside down and the curved surface portion 2b of the tubular body 20 is brought into contact with the corner 12 of the bathtub 10 while being abutted thereto, and the fixing member 6 is inverted so that the bathtub 10 is guided along the long hole 60. If the filter device 1 is positioned and fixed on both sides of the side walls 11 that sandwich the corner 12, the filter device 1 can be fixed to the corner 12 of the bathtub 10 with good accommodation. In this case, since the hot water introducing member 4 connected to the lower side of the filtering device body 2 is rotatable in the horizontal plane, it can be oriented in any direction inside the bath 10.

In any of the above cases, as shown in FIG. 2, the filtration device 1 fixes the hot water introducing member 4 close to the bottom surface 13 of the bath 10 and sinks it together with the hot water at the bottom of the bath 10. Allow foreign objects to be inhaled.

Next, the operation will be described based on examples.

When the warm water in the bathtub 10 is sucked into the warm water introducing member 4 from the water guiding port 50, relatively coarse foreign matters such as hair are separated by the filter cloth 51 inserted behind the water guiding port 50. Reach prefilter 41. Subsequently, the prefilter 41 filters the dross in the warm water, the warm water passes through the opening and the gap of the support plate 46, reaches the connecting pipe body 3, and is further guided into the filtering device body 2. .

At this time, since the pre-filter 46 is composed of fibers having antibacterial properties, it does not deteriorate even if it is immersed in warm water containing dirt such as dust for a long time, and It also has a bactericidal action on the accumulated bacteria in the dross, so that the hot water in the bathtub 10 is not contaminated.

Then, the warm water introduced into the filtering device main body 2 passes through the perforated plate 22 and the filter cloth 23, and is sterilized, deodorized, and cleaned by the granular filter material 25 filled in the tubular body 20. It is guided from the upper part of the filtering device main body 2 to the pump 7 outside the bath 10 through the hose 9, and is further returned from the hot water jet nozzle 8 into the bath 10 as a jet jet containing bubbles.

In the above process, the hot water is filtered by the hot water introducing member 4 and the filtering device main body 2, and when it reaches the hose 9, the filtration is already completed and cleaned, so that dirt is accumulated in the hose 9. It is clean because it is never done.

Further, after long-term use, foreign matters such as hair and dross accumulate in the hot water introducing member 4, so the pre-filter 41 in the hot water introducing member 4 needs to be regularly cleaned. However, in that case, do as follows.

First, the hot water introducing member 4 is pulled out horizontally along the bottom surface 13 of the bath 10 and the joining member 44 of the hot water introducing member 4 is pulled out from the joining member 31 of the connecting pipe body 3 to introduce the hot water. The member 4 is taken out of the bath 10, the cover 43 is then removed, and the pre-filter 41 together with the filter cloth 51 and the frame 42 are taken out and cleaned.

At this time, since all the cleaning is performed outside the bath 10, the work is easy and clean, and it is economical because hot water in the bath 10 does not have to be discharged.

In the above-mentioned embodiment, an example in which the filtering device 1 of the present invention is applied to a hot water circulating device in which the pump 7 and the injection nozzle 8 are connected by the hose 9 has been shown. It is also possible to implement the present invention in a hot water circulating device provided with a heating means such as a heater, a shower device using hot water in the bathtub 10, or the like.
