Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a water purifier for purifying drinking liquid.

<Prior Art> As is well known, tap water supplied to general consumers is not necessarily suitable for drinking because it contains disinfectants and has odors such as limescale odor. Therefore, recently, water purifiers containing appropriate water purifying agents have been proposed and put into practical use. Such a water purifier is used attached to a water faucet, and water from the faucet flows through a water purifying agent in the water purifier to be purified and made suitable for drinking.

This type of water purifier generally includes a water purifier main body, a water purifying cartridge containing a water purifying agent, and an upper filter member, and the water purifying cartridge and the upper filter member are housed in the water purifier main body. However, in the conventional water purifier, since the water purification cartridge and the upper filter member disposed on the inflow side of the water purification cartridge are integrally constructed, the following drawbacks and inconveniences exist. That is, the purpose of the upper filter member is mainly to remove metal particles (iron powder, rust, etc.) from clean water, and the purpose of the water purifying agent in the water purification cartridge is mainly to remove odors such as chlorine odor from clean water. ,Therefore,
Particularly when there is a lot of metal, the upper filter member becomes clogged and becomes unusable more quickly than water purifying agents. In such a case, if the water purification cartridge and the upper filter member are integrally constructed, they must be replaced as a whole even though the water purification agent can be used, resulting in a waste of relatively expensive water purification agent. It will be consumed.

<Objective of the invention> An object of the invention is to provide an improved water purifier that can efficiently use a water purifying agent and an upper filter member.

<Summary of the invention> According to the invention, there is provided a water purifier body including a lower cover body and an upper cover body detachably attached to the lower cover body, a water purification cartridge containing a water purification agent therein, and the water purification cartridge. A water purifier comprising an upper filter member that filters fluid flowing into the cartridge, wherein the water purifier cartridge and the upper filter member are individually detachably installed in the water purifier main body. Equipment will be provided.

<Preferred Specific Example of the Invention> Hereinafter, a preferred specific example of a water purifier constructed according to the present invention will be described with reference to the accompanying drawings.

In FIG. 1, which is a sectional view of the water purifier, the illustrated water purifier includes a cylindrical water purifier main body 2. As shown in FIG.
The water purifier body 2 includes a lower cover body 4 and an upper cover body 6 screwed onto the upper part of the lower cover body 4.
, and defines a space 8 therein. The upper cover main body 6 and the lower cover main body 4 are made of synthetic resin, and are transparent or translucent in specific examples. A protrusion 10 is provided on the lower side surface of the lower cover main body 4, and a supply port 12 communicating with the space 8 is formed in the protrusion 10. Therefore, a fluid such as tap water is supplied into the space 8 through the supply port 12 as indicated by the arrow 14. A protrusion 16 is also provided at approximately the center of the bottom surface of the lower cover main body 4 , and a discharge port 18 communicating with the space 8 is formed in the protrusion 16 . The protrusion 16 is removably attached to a support mounting member 22 by a mounting bolt 20, and a water supply pipe 26 is connected to an end of the protrusion 16 via a mounting bolt 24. Therefore, the liquid in the water purifier main body 8 is discharged to the outside through the outlet 18 and the water supply pipe 26. Further, as shown in FIG. 2, a plurality of (four in the specific example) protrusions 27 are provided on the inner circumferential surface of the upper cover main body 6 at intervals in the circumferential direction. Each protrusion 2
7 extends downward from the top surface of the upper cover main body 6, as shown in FIG.

A water purification cartridge 28 and an upper filter member 30 are installed in the space 8 in the water purifier main body 2 described above. The water purification cartridge 28 includes a cylindrical cartridge body 32 with an open top surface, and a plurality of holes 34 are formed in the bottom wall of the cartridge body 32. A lower filter 36 is disposed at the lower part of the cartridge body 32 (therefore, on the discharge side), and the upper part of the lower filter 36 contains activated carbon,
A water purifying agent 38, known per se, containing natural calcium and the like is contained. In a specific example,
The lower filter 36 is composed of a porous filter formed by sintering polypropylene particles, and prevents the water purifying agent 38 contained in the cartridge body 32 from falling downward. A lid 42 in which a plurality of holes 40 are formed is attached to the opening of the cartridge body 32 (therefore, on the inflow side).
In a specific example, the lid body 42 is made of synthetic resin. On the inflow side of this water purification cartridge 28,
An upper filter member 30 is provided. The upper filter member 30 includes an annular frame 44 made of synthetic resin, and the upper filter 4 is attached to this frame 44.
6 is installed. In the illustrated example,
The upper filter 46 is a sponge-like elastic filter 4.
6a and a porous filter 46b similar to the lower filter 36, the elastic filter 46a is attached to the lower part of the frame 44, and the porous filter 46b is attached to the upper part of the frame 44 (therefore, on the inflow side). (More specifically, the porous filter 46b is fixed to a stepped portion formed on the inner circumferential surface of the frame body 44 with an adhesive.)

Water purification cartridge 28 and upper filter member 3
0 is removably installed in the water purifier main body 2 as follows. That is, first, the lower part of the water purification cartridge 28 is inserted into the lower cover main body 4. Next, the upper filter member 30 is detachably attached to the inflow side of the water purification cartridge 28. Mounting of the upper filter member 30 is accomplished by inserting the lower end of the frame 44 into the open end of the cartridge main body 32. When mounted in this way, the step formed on the outer circumferential surface of the frame 44 is inserted into the cartridge. The lower end surface of the frame 44 contacts the upper surface of the lid 42 attached to the stepped portion of the cartridge main body 32. After that, remove the water purification cartridge 2.
The upper cover body 6 is attached so as to cover the upper part of the cover 8, and this is screwed onto the lower cover body 4. In this way, the water purification cartridge 28 is attached to the upper cover main body 6.
located inside the protrusion 27 (see Fig. 2),
Step portion 2 formed on protrusion 27 of upper cover main body 6
7a abuts against the upper end surface of the frame 44, and thus the water purification cartridge 28 and the upper filter 30 are installed in the water purifier main body 2 as required, as shown in FIG.

In the specific example, an annular seal member 48 is interposed between the lower cover body 4 and the upper cover body 6 to prevent the fluid in the water purifier body 2 from leaking to the outside. In addition, in order to prevent the fluid that has flowed into the space 8 of the water purifier body 2 from being directly discharged without being purified, there is a gap between the inner surface of the bottom wall of the lower cover body 4 and the lower surface of the bottom wall of the water purifier cartridge 28. An annular seal member 50 is interposed. In a specific example, the annular seal member 50 is attached to the water purification cartridge 2.
An annular protrusion 52 provided on the periphery of the lower surface of the bottom wall of 8
As shown in the figure, an annular seal member 50 is attached to the inner surface of the bottom wall of the lower cover body 4.
It is preferable to provide an annular protrusion that bites into.

In the water purifier described above, when a fluid such as clean water is supplied into the space 8 through the supply port 12, this fluid is absorbed by the inner surfaces of the lower cover body 4 and the upper cover body 6 and the outer surface of the water purification cartridge 28. The fluid is fed into the upper part of the space 8 through a defined annular space (see also FIG. 2), and the fluid passes through the porous filter 46b and the elastic filter 46a of the upper filter member 30, after which the water purifying agent 38 and the lower filter 36 before being discharged from the outlet 18 . When the fluid passes through the porous filter 46b and the elastic filter 46a, it is filtered to mainly remove metal particles, dust, etc. from the fluid. In addition, since the elastic filter 46a is deformed by the pressure of the fluid when it passes, the fluid resistance becomes smaller and the filter effect becomes larger. Further, when the fluid passes through the water purifying agent 38, it is filtered and the odor of the fluid is mainly removed.

In the water purifier configured as described above, since the upper filter member 30 is detachably attached to the water purifying cartridge 28, the upper filter member 30 and the water purifying cartridge 28 can be replaced individually, which improves efficiency. It can be used well. In particular, when there is a lot of metal, dust, etc. in the fluid, the upper filter member 30 becomes unusable, but in this case, it can be reused by replacing only the upper filter member 30.

Further, in the above water purifier, since the lower cover body 4 and the upper cover body 6 are transparent or semi-transparent, the upper filter member 30 can be visually observed through the upper cover body 6, and thus the upper filter member 30 can be prevented from clogging. The status can be monitored from the outside.

Furthermore, in the illustrated water purifier, a porous filter 46 located on the inflow side of the upper filter member 30 is provided.
Since b is made of polypropylene, the appearance will not be impaired.
