Abstract

(57) [Abstract] [PROBLEMS] To provide a bath water circulation filtration device that removes contaminants floating on the surface of bath water and prevents scales from adhering to the bath. [Structure] In a case where a water suction port 2 and a discharge port 3 attached to a bathtub 1 form a circulation water channel with a filter 5 via a pump 4, a circulation filtration water channel 7 is formed between the water suction port 2 and the bathtub 1. By providing the suction port plate 6 with the slit 9 that reaches the upper end from the vicinity of the suction port 8, the contaminants floating on the water surface of the bathtub flow down into the circulation filtration water channel 7 so as to be sucked from the slit 9, Since it is filtered by the filter 5, when drained, it is possible to prevent contaminants from depositing and adhering to the tank wall to form scale.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water circulation filter for removing contaminants floating on the bath water surface.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for a bath water circulation filter to remove contaminants floating on the surface of the bath water having a low specific gravity and preventing the contaminants from adhering to the bath.

A conventional bath water circulation filter will be described below. FIG. 3 shows the configuration of a conventional bath water circulation filtration device. In FIG. 3, 1 is a bathtub, 2 is a water suction port attached to the bathtub 1, 3 is a discharge port having an ejector nozzle attached to the bathtub 4, 4 is a pump, and 5 is a filter.

The operation of the bath water circulation filtration device constructed as described above will be described below. The bath water of the bath 1 is sucked by the pump 4 from the water suction port 2, and the filter 5
After the contaminants are removed by filtration in (1), they are discharged from the discharge port 3 as a jet jet containing bubbles. The circulation through the filter 5 is repeated to filter and clean the bath water.

[0005]

However, in the above-mentioned conventional structure, the contaminant having a large specific gravity in the bath water is filtered while repeatedly circulating through the filter 5, but the contaminant having a small specific gravity floating on the surface of the bath water is obtained. There is a problem that the substance is not sucked from the suction port 2 and remains on the surface of the bath water, and when the bath water is drained, it deposits on the wall of the bath 1 and becomes scale.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a bath water circulation filter for sucking contaminants floating on the bath water surface.

[0007]

In order to achieve this object, the bath water circulation filtration apparatus of the present invention is provided on a suction port plate mounted on the bathtub so as to cover the suction port so as to face the suction port. It has a configuration in which a slit reaching from the vicinity of the suction port to the upper end is provided.

[0008]

With this configuration, the contaminants having a small specific gravity floating on the surface of the bath water from the slits of the suction port plate attached to the bathtub enter the waterfall as the water falls inward, pass through the suction port, and pass through the filter to the filter. Therefore, the pollutant having a small specific gravity can be filtered together with the pollutant having a large specific gravity.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIGS. 1 and 2, the suction port plate 6 mounted on the tank wall of the bathtub 1 so as to cover the water suction port 2 forms a circulating filtered water channel 7 with the bathtub 1. The suction port plate 6 has a suction port 8 at a position facing the water suction port 2 at the bottom, and also has a slit 9 reaching the upper end of the suction port plate 6 above the water level of the bathtub 1 near the upper portion of the suction port 8. is doing. The number of slits 9 can be one or more.

The operation of the bath water circulation filtration device configured as described above will be described with reference to FIG. First,
When the pump 4 is operated, the bath water is sucked together with the pollutant having a large specific gravity from the suction port 8 through the water inlet 2, and the pollutant having a low specific gravity floating on the surface of the bath water is circulated through the slit 9 so that the waterfall flows down. Along with the surface flow flowing into the filtration water channel 7, the water is sucked from the water suction port 2, filtered by the filter 5 and discharged from the discharge port 3 into the bath 1.

As described above, according to this embodiment, contaminants having a large specific gravity in the bath water are sucked from the suction port 8 of the suction port plate 6, and contaminants having a small specific gravity floating on the surface of the bath water are pumped from the slit 9 by the pump 4. It is sucked in, filtered by the filter 5 and discharged from the outlet 3 repeatedly. Therefore, when the bath water is drained, contaminants on the surface of the bath water settle on the wall of the bath 1 to form scales. Can be prevented.

[0013]

As is apparent from the above description of the embodiments, the present invention is equipped with a suction port plate having a suction port and a slit on the bath wall of a bathtub, and a contaminant having a large specific gravity in bathtub water is the suction port. In addition, contaminants with a low specific gravity floating on the water surface of the bathtub are sucked by the pump from the slit, filtered by the filter and repeatedly circulated and filtered from the discharge port. It is possible to realize an excellent bath water circulation filtration device that can prevent deposits from depositing substances on the wall of the bath to form scale.
