And in this embodiment, while providing one end part 1D of the open container body 1 as said raw | natural water inlet 5 and the purified water outlet 6, the discharge port 7 which discharges the removal substance deposited on the other end part 1E is provided. Yes.

  The purification agent container 3 includes a pair of upper and lower partition plates 3a, 3b that sandwich the purification agent 2, and each partition plate 3a, 3b is provided with a plurality of holes through which water passes. The purification agent 2 is formed of activated carbon, ceramic, ion exchange resin, or the like, and purifies water by adsorbing and removing harmful components such as chalk contained in raw water. The purifying agent 2 is covered with a mesh (not shown), and the granular purifying agent 2 filled in the mesh is connected to a pair of upper and lower partition plates 3a, 3b connected via a connecting portion (not shown). Is housed in between.

  And the outline of the purifier containing body 3 is formed so as to be the same as the outline of the inner surface 1c of the container body peripheral wall portion 1a, that is, to be fitted to the inner surface 1c. By means of the rod 4 connected to 3 a, the purifier container 3 can slide on the inner surface 1 c of the container body 1.

  The discharge port 7 is provided in the reduced diameter portion 1d connected from the peripheral wall portion 1a of the container body 1 through the bottom wall portion 1b, and the accumulated removed substance can be discharged by opening and closing the valve 8. It is like that.

  In the filtration device 10 of this embodiment having such a configuration, first, as shown in FIG. 2, the purifying agent container 3 to which the rod 4 is connected is removed from the container body 1, and raw water is poured into the container body 1.

  Next, as shown in FIG. 3, the purifier container 3 to which the rod 4 is connected is attached to the container body 1 again. At this time, the inner surface 1 c of the container body 1 and the outer peripheral edge portion 3 c of the purifying agent container 3 are in sliding contact.

  Then, as shown in FIG. 4, the cleaning agent container 3 is slid toward the other end 1 </ b> E of the container body 1 with the rod 4, and the cleaning agent container 3 is placed in the container body 1 as shown in FIG. 5. Push down to the bottom wall 1b.

  The raw water poured into the container body 1 is purified by passing through the purification agent container 3 to become purified water, and finally, as shown in FIG. Can be taken out.

  Further, the removed substance captured by the purifier container 3 being pushed in is deposited on the bottom wall 1b or the reduced diameter part 1d of the container body 1, and the deposited removed substance is discharged by opening the valve 8. be able to. At this time, cleaning water may be allowed to flow from the upper partition plate 3a side.

  The seat valve 15 is contoured so as to cover the top surface 3d of the upper partition plate 3a in an airtight state in plan view, and the purifying agent container 3 is drawn into the one end 1D side of the container body 1. In this case, the outer peripheral edge portion 15a slides to maintain an airtight state, and when it is pushed into the other end portion 1E, the airtight state is released.

  In this embodiment, the tip 4a of the rod 4 and the upper partition plate 3a are connected via an opening (not shown) provided in the seat valve 15, and the rod 4 is closed so as to close the opening. The front end portion 4 a is joined to the seat valve 15. The tip 4a of the rod 4, the seat valve 15, and the upper partition plate 3a may not be bonded independently.

  In the filtration device 10A of this embodiment having such a configuration, first, as shown in FIG. 8, the rod 4 is pulled up to slide the purifier container 3 and the seat valve 15 toward the one end 1D side of the container body 1. As a result, the space 25 on the other end 1E side of the container body 1 is depressurized from the purifier container 3, the backflow prevention valve 18 is opened, and the raw water is drawn into the space 25.

  Then, as shown in FIG. 9, the purifier container 3 and the seat valve 15 are pulled up to a position near the top wall portion 21 b of the main body container 21, and raw water is stored in the space portion 25.

  Next, as shown in FIG. 10, the rod 4 is pushed in to slide the purifying agent container 3 and the seat valve 15 toward the other end 1E side of the container body 1, and as shown in FIG. The container 3 is pushed into the bottom wall portion 22 a of the lid body 22. When the rod 4 is pushed in, the space 25 is pressurized and the backflow prevention valve 18 is closed, and the raw water confined in the container body 1 passes through the purifier container 3 and enters the seat valve 15. By abutting, the outer peripheral edge portion 15a is bent so that the seat valve 15 is bent in a U shape, and the purified water that has passed through the gap formed between the seat valve 15 and the inner surface 21c of the peripheral wall portion 21a is the purifier container. 3 accumulates in the space 26 on the one end 1D side of the container body 1.

  Then, as shown in FIG. 12, when the rod 4 is pulled up again and the purifier container 3 and the seat valve 15 are slid toward the one end 1D side of the container body 1, the backflow prevention valve 18 opens and the raw water Is drawn into the space portion 25 again, and the purified water stored in the space portion 26 is pushed by the seat valve 15 so that it is discharged from the purified water outlet 16.

  Next, as shown in FIG. 13, when the purified water stored in the space 26 is discharged to some extent, the rod 4 is pushed again as shown in FIG. By repeating such operations, the purified water that has passed through the purifier container 3 can be taken out from the purified water outlet 16, and the removed substance contained in the raw water is deposited on the bottom wall portion 22 a of the lid body 22. .

  Finally, as shown in FIG. 15, the removed substance deposited on the bottom wall portion 22 a of the lid body 22 can be discharged by removing the fitted lid body 22 from the container body 21.

  As described above, in this embodiment, the container body 1 includes a container body 21 in which the water purification outlet 23 is provided at one end 1D of the container body 1 and the discharge port 17 is provided in the other end 1E. The lid body 21 is detachably attached to the discharge port 17 of the container body 21 and has a raw water inlet 15 formed therein.
