Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub filter, and more particularly to a bathtub filter attached to a drainage outlet of a bathtub.

[0002]

2. Description of the Related Art As a filter for a bath water circulation system, which is designed to return water to a bath after filtering the water in the bath with a filter provided at a drain outlet of the bath, the one described in Japanese Utility Model Publication No. 3-122785. There is.

In the bathtub filter of the same publication, a tubular body is attached to a drainage outlet of a bathtub wall, and a cylindrical filter with a bottom is arranged in the tubular body.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the bathtub filter described in Japanese Patent No. 785, the filter is configured to capture both scales and lint, and when it becomes clogged, the filter is replaced with a new one. It was a so-called disposable type that discarded what was used.

An object of the present invention is to provide a bathtub filter in which the filter medium can be easily washed and reused.

[0006]

A bathtub filter according to a first aspect of the present invention is a bathtub filter attached to a drainage outlet of a bathtub, and a hair catcher provided at a filter inlet portion facing inside the bathtub. It is characterized in that it is provided with a granular filter medium arranged after the hair catcher.

A bathtub filter according to a second aspect of the present invention is the bathtub filter of the first aspect, wherein the bathtub filter has a bathtub water receiving port that opens into the bathtub at a front end and a filtered water discharge port at a rear end. The outer casing is fixed to the bathtub, and the inner casing is arranged so that it can be inserted into and removed from the outer casing and has an inflow part and an outflow part of water, and the hair catcher is a bath water receiving port of the outer casing. And the granular filter medium is filled in the inner casing.

[0008]

In the bathtub filter of the present invention, the hair catcher captures the fluff and the particulate filter material supplements the scale. If hair debris builds up on the hair catcher, it can be easily removed by hand. When a large amount of scale has adhered to the granular filter material, the granular filter material is taken out, washed with water and reused.

In the bath filter according to the second aspect of the present invention, when the granular filter material is washed, the granular filter material is taken out from the outer casing together with the inner casing. Then, the inner casing containing the granular filter medium is shaken in water, or the granular filter medium is taken out from the inner casing and washed with water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view of a bathtub filter according to an embodiment, FIG. 2 is an exploded perspective view of the same, and FIG. 3 is an exploded perspective view of an inner casing.

A drainage outlet 2 is provided on the bath wall 1 of the bathtub, and a bathtub filter 3 is attached to the drainage outlet 2. In this bathtub filter 3, a hair catcher 5 is arranged at an inlet portion (bathwater inlet / outlet portion of the outer casing 4), and an inner casing 6 is arranged inside the outer casing 4. Is filled with granular filter material 7.

The outer casing 4 comprises a cylindrical main body 8 and an annular mounting member 9 screwed onto the cylindrical main body 8. The cylindrical main body 8 has a bottomed cylindrical shape, and the male screw of the annular attachment 9 is screwed into the female screw provided on the inner circumference of the tip, and the flanges 8f and 9f of both sides allow the edge portion of the drainage port 2 to be Is sandwiched between. A filtered water discharge port 10 is provided at the rear end of the tubular body 8 of the outer casing 4.

A stepped portion 9a provided on the inner circumference of the annular attachment 9
On the other hand, the step 6a on the outer periphery of the inner casing 6 is locked. The inner casing 6 has a cylindrical shape, and the hair catcher 5 is screwed to the water inflow portion at the tip. A mesh holder 11 is screwed to the outflow portion at the rear end. 5
Reference numerals a and 11a denote stainless meshes provided on the hair catcher 5 and the mesh holder 11, respectively.

A cover cap 12 is detachably attached to the annular attachment 9 so as to be fitted onto the annular attachment 9.

In the thus-configured bathtub filter 3, the hair catcher 5 captures the shavings, and the particulate filter material 7 supplements the scale. When the hair catcher 5 has accumulated debris, remove the cover cap 12,
Easy to remove with your fingertips. When a large amount of scale has adhered to the granular filter medium, the granular filter medium 7 is taken out, washed with water and reused. In this case, first, the cover cap 12 is removed, the knob 5b of the hair catcher 5 is pinched, and the hair catcher 5 and the inner casing 6 are pulled out from the outer casing 4. Then, the inner casing 6 containing the granular filter material 7 is shaken in water to disperse and remove the scales in the water. In addition, the hair catcher 5 or the mesh holder 5
Alternatively, the granular filter material 7 may be taken out to a washbasin or the like and washed with water.

In the above embodiment, the inner casing 6 is made of a metal or synthetic resin tubular body, but a window hole may be formed in the side peripheral surface of the inner casing 6 and a mesh may be provided in the window hole. . In this way, the water pressure loss is reduced.

In the present invention, each member (made of metal or synthetic resin) constituting the filter may be subjected to antibacterial treatment. By doing so, it is possible to prevent slime from occurring in each member.

[0018]

As described above, according to the bath filter of the present invention, the hair debris is trapped by the hair catcher, and the dross is trapped by the granular filter material, and both are separately trapped. Therefore, the granular filter medium can be easily purified by washing with water, and the granular filter medium can be reused repeatedly.

According to the bathtub filter of claim 2,
It is very easy to wash the granular filter material.
