As a result, the hot and cold water flowing through the inflow pipe 16 flows into the branch pipe 20, passes through the second three-way joint 17b, and flows from the filtration outflow pipe 3 into the filtering device 1. The hot and cold water that has flowed into the filtering device 1 separates dirt, dust and the like adhering to the filter medium 8 and the filter bed 7 (see FIG. 2) from the filter medium 8 and the filter bed 7. It is drained to the outside via the first three-way joint 17a and the drainage pipe 19. In this case, the hot and cold water in the bathtub 9 used for backwashing is limited to clean hot and cold water that no one is bathing. In FIG. 2, the hot and cold water that has followed the filtration route shown in FIG. 3 flows into the filtration device 1 from the filtration inflow pipe 2, is scattered by the water spray plate 6 a and the separation plate 5, and passes through the filter medium 8 and the filter bed 7. The dirt and dust are filtered out.
The hot and cold water purified by the filter medium 8 and the filter bed 7 is used as the water spray plate 6b.
Through the filtration device 1 to the filtration outflow pipe 3. On the other hand, the hot and cold water that has followed the cleaning route shown in FIG. 4 flows into the filter 1 from the filtration outflow pipe 3, is dispersed by the water sprinkling plate 6b, and the filter bed 7 provided to prevent the outflow of the filter medium 8 during the filtration operation is removed. The dirt and dust adhering to the filter medium 8 that has passed through the cleaning process is removed by the filter medium 8
Separate from. At this time, the hot water contains air bubbles generated by the jet jet. The bubbles raise the filter medium 8. The bubbles and the floated filter medium 8 collide with the separation plate 5, and the impact causes the filter medium 8 to settle. Furthermore, when the filter medium 8 that does not collide with the separation plate 5 or escapes settling due to the impact of the collision passes through the narrow flow path between the side wall of the filtration device 1 and the separation plate 5, the impact of the water flow. It is configured so that it will sediment and will not flow out of the filtering device 1.

になり、微細なゴミや垢等がほぼ完全に除去される。The filtration of hot water and the cleaning of the filtration device 1 will be described by using the filtration device 1 configured as described above in the general bath water filtration device shown in FIGS. 3 and 4 as in the conventional example. The flowing path of hot and cold water at the time of filtration and washing is the same as in the case of the conventional example, and therefore its description is omitted. <Filtration of Hot Water> During filtration, hot water containing dust, dirt, and hair that has flowed into the inflow chamber 24 from the inflow pipe 23 is first removed by the filter 28a from large dust, hair, and the like. Next, the hot and cold water from which large dust and hair have been removed passes through the connecting tube 27, and fine dust and dirt are removed by the filter 28b. When the hot and cold water having entered the filtration chamber 26 passes through the filter medium 29 and the filter bed 30, finer dust and dirt are removed. The hot and cold water filtered in this way passes through the outflow chamber 31 to the outside of the filtration device 1 through the filtration outflow pipe 32, and is circulated in the bath 9 or the like. It should be noted that large dust, dirt, hair and the like removed by the filters 28a and 28b stop in the inflow chamber 24 when the operation of the jet pump 12 is stopped and never enter the filtration chamber 26. As described above, according to this embodiment, the quadruple filtration is substantially performed, and fine dust and dirt are almost completely removed.

び２８ｂを清浄な状態に保つことが可能である。<Cleaning of Filtration Device> When backwashing, clean hot and cold water in a state where no one is bathing in the bathtub is used as the hot and cold water for washing. The hot water for cleaning flows into the outflow chamber 31 from the outflow pipe 32, and flows into the filtration chamber 26 while cleaning the filter bed 30 and the filter medium 29. At this time, fine dust, dirt, etc. adhering to the filter bed 30 and the filter medium 29 are released, and as a result, the hot water flowing into the filtration chamber 26 contains these fine dust, dirt, etc. The hot and cold water containing fine dust or the like cleans the filter 28b when flowing into the communication tube 27. Further, the filter 28b is also washed when flowing into the inflow chamber 24 from the communication cylinder 27. In this way, the filter bed 30, the filter medium 29, the filters 28a and 28b are washed, and the hot and cold water containing the dirt passes from the inflow chamber 24 through the inflow pipe 23 and the filtering device 1
Is discharged to the outside. The inflow pipe 23 is the housing 2 of the filtration device 1.
Since it is provided at the bottom of 2, the hot water (waste liquid) containing waste hardly remains inside the inflow chamber 24 (or the housing 22), and the filter bed 30, the filter medium 29, and the filters 28a and 28b are cleaned. It is possible to keep the condition.

る。As described above, according to the filtration apparatus of the present invention, the inside of the housing is divided into the inflow chamber, the outflow chamber, and the filtration chamber, and each of the two ends of the communication cylinder that connects the inflow chamber and the filtration chamber is divided. Since the filters having different meshes are provided and the quadruple filtration structure is substantially realized, the filtration performance of the filtration device can be improved. Furthermore, in the cleaning of the filtration device, the waste liquid that has washed the filter bed, the filter medium and each filter is almost completely discharged from the inflow pipe provided at the bottom of the housing of the filtration device, and almost no filth remains inside the housing. Sufficient cleaning of the floor, the filter medium and each filter can be realized, and the filtration performance of the filtration device can be maintained in a state close to the initial state.
