Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a water purifier most suitable for households, which uses a filter medium such as activated carbon to remove residual chlorine, odor, dust, etc. in the raw water of the tap water.

(B) Conventional Technology Conventionally, for example, a water purifier disclosed in Japanese Patent Laid-Open No. 59-46185 has a cartridge that filters raw water from a tap water through an upper end opening and discharges it as purified water to the outside. In this cartridge, a cylindrical prefilter having an opening at the lower end is arranged inside the upper part, and the lower part thereof is filled with activated carbon. In general, in the cartridge with the above-mentioned structure, the case of the cartridge and the case covering the cartridge are made of a transparent material so that the prefilter can be seen from the outside, and the cartridge can be replaced depending on how dirty the prefilter is. Although the time is decided, the visible range of the prefilter covers the entire upper surface and the entire circumference of the side, and even a little dirt gives the user a feeling of being unclean.

(C) Problems to be solved by the present invention The present invention is to provide a water purifier that does not give the user a feeling of uncleanness by reducing the visible range of the porous filter in consideration of the above-mentioned drawbacks. .

(D) Means for solving the problems In the water purifier of the present invention, the porous filter of the cartridge tank is embedded in the filter medium, and the end of the porous filter is brought into contact with the inner surface of the upper case to introduce the inlet and the inlet. The exit is divided.

(E) Action With the configuration of the present invention as described above, the portion of the porous filter that can be seen from the outside of the case can be only the end portion.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings. (1) is a cylindrical storage part having an opening on the upper surface and an insertion hole (2) formed on the lower surface.
(3) and a switching unit (5) having a cylindrical communication pipe (4) having one end open and the other end connected to the side wall of the storage unit (3), the storage unit (3) ) And the communication pipe (4), the storage section (3)

Is an upper case formed of a transparent material with an opening on the lower surface, and a step portion (25A) is formed on the inner peripheral surface of the upper portion. (26) is a lower case composed of a partition cylinder (27) and a discharge member (28), the partition cylinder (27) is a cylinder (30) in which a step portion (29) is formed on a substantially central outer peripheral surface. And a plurality of through holes (3
1), (31) ... Formed flange (32), and a plurality of connecting members (33), (33) ...
This flange consists of a ring member (34) connected to (32)
A plurality of inflow ports (35), (35) ... Are formed by the (32), the connecting member (33) and the ring member (34). In addition, the discharge member (2
8) is formed in a funnel shape and a cylindrical shape, and has a groove portion (36) for accommodating the flange (32) of the partition cylindrical body (27) on the outer periphery of the upper end, and an upper surface opening (37) (Hereinafter referred to as ") is approximately the same size as the lower surface opening of the cylindrical body (30) of the partition cylindrical body (27), and the lower surface opening (38) (hereinafter referred to as the discharge port) is a size that is not blocked by the surface tension of water. There is. (39) and (39) are metal net filters provided at the inflow ports (35), (35), ... And the outflow port (37), and the filter medium to be described later has an upper case (25) and a lower case (27). ) To prevent leakage to the outside. (40) is a cylindrical porous filter made of foamed polyethylene that removes red rust, dust, etc. of raw water.The outer flange (40A) is formed on the outer circumference at the upper end, and the inner flange (40B) is formed on the inner circumference at the lower end. ing. Reference numeral (41) is a filter medium made of activated carbon containing silver added to fill the upper case (25) and the lower case (26), which can remove residual chlorine, odor, dust and the like and can be sterilized by silver.

To assemble the cartridge storage tank having the above-described structure, first, the porous filter (40) is housed in the upper case (25), and the upper surface of the outer flange (40A) of the porous filter (40) is placed in the upper case ( 25) on the stepped part (25A) and the tip surface is the upper case (2
Abut the inner peripheral surface of 5), and the cylinder of the partition cylinder (27).
(30) is inserted into the porous body filter (40), the inner flange (40B) of the porous body filter (40) is brought into contact with the step (29) of the tubular body (30), and the ring member (34) is turned up. It adheres to the inner circumference of the lower part of the case (25). At this time, the porous filter (40) is
It is clamped and fixed by the step portions (25A) and (29) of the (25) and the tubular body (30). After this, the cylinder (3) of the partition cylinder (27)
