(For example, the door 9) is opened or closed in the residual pressure discharge passage 26 connected to any one of the water filters of the water filters 1-4, (B) for the residual pressure discharge passage to open or close the residual pressure discharge passage (26) by the valve cartridge (10) rotated by the valve cartridge

(For example, a cock 8 or a fauset 21 can be used) for discharging the purified water purified by the water filter.

At this time, the residual pressure discharge passage opening / closing valve B is the same as the structure of the raw water moving passage opening / closing valve A, and when the door 9 is opened or closed, the residual pressure discharge passage opening / The operation of opening and closing the discharge passage 26 is opposite to the opening / closing of the raw water moving passage 6 by the opening / closing valve A for the raw water moving passage, and a detailed description thereof will be omitted.

The raw water flow passage opening / closing valve (A) or the residual pressure discharge passage opening / closing valve (B)

A valve body 13 mounted on the purifier body 5 and having an inlet 11 and an outlet 12 through which fluids are introduced and discharged;

A valve cartridge 10 rotatably coupled to the valve body 13 when the valve cartridge 10 is rotated at an arbitrary angle (for example, 90 degrees) by opening and closing the door 9, 14 and a sealing member 15 (for example, a packing is used) 15 to communicate or block the inlet 11 and the outlet 12;

And a connection pin 16 for rotatably connecting the valve cartridge 10 to the door 9.

The door 9 is formed at one side of the outer surface of the valve body 13 and opens the door 9 to communicate or block the inlet 11 and the outlet 12, And a rotation restricting tine 17 for restricting rotation.

And a separation preventing protrusion 18 protruding from a predetermined position on the outer surface of the door 9 and preventing the connection pin 16 from being detached from the valve cartridge 10.

The external force supply source (referring to the door 9 as an example) can be rotatably mounted on the purifier body 5 and the valve body 13.

Although not shown in the drawing, the internal residual pressure discharge from the purifier main body 5 when the residual pressure discharge passage opening / closing valve B is opened, with the door 9 opened,

[

A ball valve or a ceramic cartridge valve may be used as the raw water flow passage opening / closing valve (A) or the residual pressure discharge passage opening / closing valve (B).

5, the valve cartridge 10 and the connecting pin 16 of the raw water passage passage opening / closing valve (A) or the residual pressure releasing passage opening / closing valve (B)

In order to prevent the rotation of the connection pin 16 when the rotational force of the door 9 is transmitted to the valve cartridge 10 through the connection pin 16, (For example, the key and the corresponding keyway may be formed as a keyway).

Hereinafter, an example of using a water purifier including a valve for opening and closing the flow path of the door according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2 (b) and FIG. 6, when the purifier body 5 is closed with the door 9, the opening / closing valve A for the raw water flow path is kept open. That is, the inlet 11 and the outlet 12 are communicated with each other by the connection hole 14 of the valve cartridge 10.

The raw water supplied from the raw water supply source sequentially passes through the inlet port 11 of the raw water flow passage A and the outlet port 12 of the valve body 13, 13).

The raw water passing through the discharge port 12 passes through the raw water transfer passage 6 and is supplied to the inlet port of the first front water filter 1 of the water filter 1-4.

At this time, the raw water introduced into the water filter 1 (referred to as a sediment filter) is filtered by a nonwoven fabric, which contains rust, soil, suspended solids and the like contained in the raw water, (Hereinafter referred to as UF) -water filter 4 (referred to as a post-carbon filter). The structure for filtering foreign substances harmful to the human body contained in the raw water by the water filter (1-4) is a technical content used in the related art, and therefore, detailed description thereof will be omitted.

3 (b), when the door 9 is kept closed in the water purifier main body 5, the residual pressure discharge passage opening / closing valve (B) provided in the residual pressure discharge passage (26) Is kept closed. The inlet 11 and the outlet 12 of the residual pressure discharge passage on-off valve B are closed by the sealing member 15 formed in the valve cartridge 10.

6 (a) and 6, the door 9 is opened to replace at least one water filter of the water filters 1, 2, 3, 4 provided in the water purifier main body 5, The valve cartridge 10 of the opening / closing valve for the moving water passage A is rotatably connected to the door 9 by a predetermined angle (for example, 90 degrees).

Therefore, the inlet port 11 and the discharge port 12 of the raw water flow path opening / closing valve A are closed by the sealing member 15 formed in the valve cartridge 10. Therefore, the raw water passage 6 for supplying the raw water to the first front water filter 1 out of the water filters 1, 2, 3, 4 is shut off.

3 (a), due to the opening of the door 9, as the valve cartridge 10 connected to the door 9 is rotated, the connection hole 14 of the valve cartridge 10 (11) and the discharge port (12) of the residual pressure discharge passage on / off valve (B).

The residual pressure discharge passage 26 is opened due to the opening of the residual pressure discharge passage opening / closing valve (B). Therefore, the residual internal pressure remaining in the water filters (1, 2, 3, 4) can be discharged through the residual pressure discharge passage opening / closing valve (B).

When the door 9 is opened as described above, the raw water flow path 6 is blocked by the raw water flow path opening / closing valve A and the residual pressure discharge valve B is closed by the residual pressure discharge path opening / By opening the passage 26, it is possible to replace the corresponding water filter of the water filter (1-4) with the internal residual pressure removed from the water filter (1, 2, 3, 4).
