  Therefore, when the filtration cartridge 20 is rotated in one direction with the joint 36a facing the purified water outlet 31 as shown in FIG. 6 (a), the male screw portion 33a becomes the female screw as shown in FIG. 6 (b). It is screwed into the portion 33 a and attached to the attachment portion 22 and accommodated in the case 21. Accordingly, the joint 36a is inserted into the purified water outlet 31 and the purified water outlet pipe is connected to the purified water outlet 31, while the raw water inlet pipe is connected to the raw water inlet 37a and the raw water from the raw water inlet 32 is connected to the raw water inlet 37a. Can be introduced.

  A case 21 (hereinafter abbreviated as “case 21”) in which the filtration cartridge 20 is accommodated is attached to the attachment member 10 by engaging both locking pins 25 of one side plate 24 with both hole portions 17. That is, as shown in FIG. 7, the interval L1 between both locking pins 25 of the side plate 24 is set equal to the interval L2 between both hole portions 17, and each locking pin 25 includes a head portion 25a and a shaft portion 25b. The shaft portion 25b is screwed to the side plate 24. The diameter of the head portion 25 a is set smaller than the diameter of the round hole 19 and larger than the widths of the long hole 18 and the pore 20.

  Therefore, when the case 21 is attached to the attachment member 10, first, as shown by an arrow S1 in FIG. 7, both locking pins 25 of one side plate 24 are inserted into the circular holes 19 of the opposing plate material. At this time, the case 21 is disposed below the decorative board 7 as shown in FIG.

  Next, the case 21 is pushed in the Y direction (the depth direction of the storage cabinet 2), the both locking pins 25 are moved into the long holes 18, and the case 21 is disposed inside the decorative plate 7. In this state, the case 21 is lifted, and as shown by an arrow S2 in FIG. 7, the shaft portion 25b of both locking pins 25 is raised along the long hole 18, and the case 21 is brought into the dead space T of the storage cabinet 21. Arrange.

  Further, an arbitrary pore 20 is selected and the case 21 is pushed in the Y direction so that the shaft portion 25b of the locking pin 25 enters the selected pore 20. At this time, the head portion 25a is locked to the inner peripheral edge of the opposing pores 20 of the plate material. Thereby, the filtration cartridge 20 is arrange | positioned at the back of the dead space T, as shown to the broken line of FIG. 2, and the space in the storage cabinet 2 can be used effectively.

  Moreover, since the height of each pore 20 differs in the attachment member 10, the user can attach the case 21 to the attachment member 10 adjusting to arbitrary height. Further, since the pore 20 is slightly inclined in the downward direction Q, it is difficult to return to the long hole 18 side due to vibration or the like, and the filtration cartridge 20 is regulated by the stopper piece 29, so that it can be prevented from falling off. The filtration cartridge 20 may be attached to the attachment member 10 by using the other both locking pins 25 of the case 21.

(2) Replacement Procedure of Filtration Cartridge 20 The replacement of the filtration cartridge 20 includes (A) an operation of removing the case 21 in which the filtration cartridge 20 is accommodated (here, abbreviated as case 21) from the mounting member 10; An operation of attaching the case 21 containing the exchanged filtration cartridge 20 to the attachment member 10 is performed. Since this operation (B) is the same as the above-described mounting operation, description thereof is omitted. Here, the removal operation (A) will be mainly described.

  In this operation (A), the case 21 is first pulled toward the front (X direction in FIG. 2) so that the shaft portion 25 b of the locking pin 25 enters the elongated hole 18. At this stage, the case 21 is located inside the decorative board 7.

  Next, the case 21 is lowered, the shaft portion 25 b of the locking pin 25 is lowered along the long hole 18, and the case 21 is disposed below the decorative plate 7. Thereafter, the case 21 is pulled forward, and the shaft portion 25 b of the locking pin 25 enters the round hole 19. In this state, the filtration cartridge 20 is pulled in the X direction and removed.

  At this time, although the attachment portion 22 slides in the X direction, the purified water outlet pipe and the raw water introduction pipe are smoothly guided by the rotation of the guide roll 26, and the bending and disconnection thereof are prevented. Specifically, the filtration cartridge 20 can be easily removed from the mounting portion 22 by rotating in the other direction to release the screwing of the male screw portion 33a and the female screw portion 34b.

  Therefore, according to the mounting structure of the water purifier 15, the filter cartridge 20 can be simplified by avoiding the decorative plate 7 by moving both the locking pins 25 along the holes 18 to 20 in the direction opposite to the mounting direction. In this sense, the workability of the replacement work of the filtration cartridge 20 can be improved.

  The new filtration cartridge 20 replaced after the removal is accommodated in the case 21 (here, the case 21 itself is meant). In this case, first, the attachment portion 22 is moved in the front X direction, and the filtration cartridge 20 is rotated in one direction with the attachment portion 22 held down, so that the male screw portion 33a is screwed into the female screw portion 33a.
