A first lid 6 that can be opened and closed is attached to the upper end of the first case 15 via a plurality of fasteners 6a, and a second lid 7 that can also be opened and closed is attached to the upper end of the second case 5b. Is attached through. Further, as shown in FIG. 1C, a viewing hole 5a is formed on the vertical surface of the stepped portion.
[0012]
As shown in FIG. 2A, a substantially trouser-shaped bottom member 8 made of resin is attached to the lower end of the second case 5b, and the elbow pipes 9 and 8b are respectively attached to the cylindrical leg portions 8a and 8b of the bottom member 8. The hair catcher 12 is formed by attaching a fine mesh net cage 11 to the upper portion of the cylindrical leg portion 8b. The end of the elbow pipe 9 is connected to the suction port 1a as shown in FIG. 2 (c), and the end of the elbow pipe 10 is connected to the suction port 13a of the pump 13 via the connecting pipe 14 as shown in FIG. Connected. Accordingly, the water sucked from the suction port 1a is introduced into the cylindrical leg portion 8a through the elbow pipe 9, flows laterally from the upper end portion thereof, and flows into the other cylindrical leg portion 8b. It flows down the cylindrical leg portion 8b, passes through the elbow pipe 10 and the connecting pipe 14, and is fed into the suction port 13a of the pump 13.
[0013]
As shown in FIG. 2B, the first case 15 has a partition plate 16 attached to the upper end of the hemispherical bottom portion 15a, and an introduction tube 15b is provided in the center of the partition plate 16 so as to protrude upward. An elbow pipe 17 is connected to the lower end of the introduction pipe 15b. The end of the elbow pipe 17 is connected to the discharge port 13b of the pump 13 through a connecting pipe 18 as shown in FIG. Accordingly, the water discharged from the pump 13 is introduced into the first case 15 through the connecting pipe 18, the elbow pipe 17, and the introduction pipe 15 b.
[0014]
Inside the first case 15, as shown in FIG. 1B, a plurality of cylindrical cartridge filters 19 are detachably arranged around the introduction pipe 15b at intervals in the circumferential direction. As shown in FIG. 2B, the hollow portion 19a of the filter 19 passes through the partition plate 16 and communicates with the bottom portion 15a of the first case 15, and further communicates with an elbow pipe 20 attached to the discharge hole 15c of the bottom portion 15a. ing. The end of the elbow pipe 20 is connected to the discharge port 1b of the filter 1 via a connecting pipe 21 (FIG. 3). Thereby, the filtration part 22 is comprised, and the water discharged | emitted from the discharge hole 15c of the said 1st case 15 is discharged from the discharge port 1b of the filter 1 through the elbow pipe | tube 20 and the connecting pipe 21. .
[0015]
The bottom 1c of the filter 1 is composed of support members 23 and 24 attached to the frame at the lower end of the cover 5 as shown in FIG. The casters 4 are attached to both ends, and the pump 13 is fixed to the upper surface of the support member 23. Although not shown, the pump 13 is provided with a pressure gauge, and this pressure gauge is positioned facing the peephole 5a of the cover 5 so that the pointer of the pressure gauge can be seen through the peephole 5a. It is. In FIG. 1C, 25 is a wiring cord and 26 is a switch.
[0016]
The filter 1 of the present invention thus configured is used by being attached to a stationary child pool 27 as shown in FIGS. 4 (a) and 4 (b). In this use, the suction hose 28 is connected to the suction port 1 a of the filter 1, and the end of the suction hose 28 is connected to the drain port 27 a of the pool 27 for children, and is connected to the discharge port 1 b of the filter 1. The discharge hose 29 is connected, and the end thereof is temporarily fixed to the edge of the child pool 27 with a clamp 30 or the like. In this case, since the suction port 1a and the discharge port 1b of the filter 1 are located on the opposite side surfaces, the filter 1 can be placed in close contact with the children's pool 27, and the suction hose 28 and the discharge hose. Since 29 can be swung along the outer periphery of the children's pool 27, it does not get in the way. By operating this filter 1, it is possible to clean the water in the pool while circulating it. 31 is a drain valve for discharging the water in the pool.
[0017]
When the opening / closing valve of the drainage port 27a of the pool 27 for children is opened, a part of the water in the pool flows out, passes through the suction hose 28, and is sucked from the suction port 1a of the filter 1 with the opening / closing valves 2, 3 open. It is. At this time, since the hair catcher 12 is lower than the pool water level, so-called priming is not required.
[0018]
The water sucked from the suction port 1a flows into the cylindrical leg portion 8a at the bottom of the hair catcher 12 through the elbow tube 9 as described above, and is further sucked up to the upper end portion to flow sideways and adjacent to the cylindrical shape. It flows into the upper part of the leg 8b. When the water that has flowed into the cylindrical leg portion 8b passes through the mesh basket 11, hair loss, lint, large dust, and the like mixed in the water are captured.
[0019]
In this case, the water is sucked up from below and the flow is once changed in the lateral direction, and then passes through the mesh basket 11, so that the flow rate does not fluctuate and the trapping action by the mesh basket 11 is performed smoothly and efficiently. In addition, since the conventional hair catcher is a method in which water passes in the horizontal direction as described above, the trapped material may accumulate on the side surface of the mesh basket, which may hinder the flowing water. Therefore, even if the trapped material accumulates at the bottom of the net basket 11, the flowing water passes through the side of the net basket 11, thereby preventing the water flow from being inhibited.
[0020]
When the second lid 7 is removed, the mesh basket 11 can be lifted and easily removed from the cylindrical leg portion 8b. For this reason, when the trapped material is accumulated, the net basket 11 can be taken out, discarded, and then attached to the cylindrical leg portion 8b, and the second lid 7 can be attached. If the second lid 7 is formed of a transparent material, it is convenient to observe the trapped substance accumulation from the outside through the second lid 7.
[0021]
The water that has passed through the net cage 11 flows down the cylindrical leg portion 8 b and flows into the elbow pipe 10, and flows from the elbow pipe 10 through the connecting pipe 14 to the suction port 13 a of the pump 13. Then, the water discharged from the discharge port 13 b of the pump 13 flows into the first case 15 of the filtration unit 22 through the connecting pipe 18 and the elbow pipe 17.
[0022]
The water flowing into the first case 15 through the introduction pipe 15b enters the side surfaces of the plurality of cylindrical cartridge filters 19 arranged in the circumferential direction and is filtered when reaching the hollow portion 19a. This filtration removes fine dust, impurities and the like mixed in the water. In this case, since the water flows in from the bottom of the first case 15 and is stored, it enters the plurality of cartridge filters 19 at a slow flow rate, and the filtration action is carefully and efficiently performed. It can be carried out. Further, since the upper end of the first case 15 opens when the first lid 6 is removed, the cartridge filter 19 can be easily replaced.
[0023]
As described above, since the plurality of cartridge filters 19 are disposed in the first case 15 along the circumferential direction, a plurality of filter housings H for housing the cartridge filters as in the conventional case are not required. In addition, the height can be suppressed by using a low cartridge filter. Thereby, the filtration part 22 can be reduced in size and size.
[0024]
The water (clean water) filtered by each cartridge filter 19 joins in the bottom portion 15a of the first case 15, flows into the elbow pipe 20 through the discharge hole 15c, passes through the connecting pipe 21 and passes through the connecting pipe 21. It flows into the discharge hose 29 from the discharge port 1b. The clean water that has flowed into the discharge hose 29 is returned from the end of the discharge hose 29 into the child pool 27. In this way, the water in the children's pool 27 can be purified while circulating part by part.
[0025]
After use, the filter 1 removes the suction hose 28 and the discharge hose 29, and after maintaining the pump 30 and the like, stores it in a warehouse or the like. Further, the bottom 1c of the filter 1 has a frame structure and thus has excellent air permeability, so that moisture does not accumulate inside the filter 1 during storage and the components such as the pump 13 are maintained in a good state. Can do.
[0026]
