A male screw 18 is engraved on the surface of the portion 17.

On the inner surface side of the opening 19 formed in the tubular portion 17, the mesh filter for collecting the suspended solids, which collects and filters dust and debris floating on the surface of the hot water, is used. A is provided.

Further, the locking piece portion 17 a is locked with the filter housing body 21 in which the dust collecting mesh filter B is mounted, and is integrated with the rotary lid holder 10 in the state described above. It is attached to the lower opening of the cover body 6 or is connected so that it can be taken out. Although not shown, the locking piece portion 17a and the filter housing body 21 are disengaged from each other after the locking end portion of the filter housing body 21 is inserted into the groove formed in the locking piece portion 17a. The filter housing 21 is locked by turning it in a fixed direction, and released by turning it in the opposite direction.

As shown in FIG. 3, the fixed body 11 has a ring-shaped main body 20 formed to have a diameter larger than the diameter of the suction port 4, and is engraved on the inner peripheral surface of the main body 20. It is composed of a female screw portion 22 and a tubular portion 23 integrally provided on the back surface side of the body portion 20.

The tubular portion 23 is formed in a substantially U-shaped cross section, has a diameter smaller than the diameter of the suction port 4, and has a male screw 24 on the surface side of the tubular portion 23. It is carved. Incidentally, reference numeral 23a in the figure denotes a plurality of windows formed in the body of the cylindrical portion 23.

In the fixed body 11 configured as described above, the male screw 24 engraved on the front surface side of the cylindrical portion 23 is attached to the holder 12 (FIG. 1 and FIG. 3), it is screwed with a female screw 25 formed on the inner peripheral surface of the end portion to firmly fix the holder 12 to the outside of the bath of the suction port 4. In addition, the symbol P in the drawing is a packing fitted in the suction port 4.

Further, a male screw 18 engraved on the rotary lid holder 10 is screwed into a female screw portion 22 engraved on the inner peripheral surface of the main body portion 20.

The dust collecting mesh filter B has a finer mesh than the floating substance collecting mesh filter A so as to collect and filter finer dust than the floating substance collecting mesh filter A. The filter material is formed into a substantially U-shaped cross section and is detachably mounted in the filter housing body 21.

The outer diameter of the dust collecting mesh filter B is smaller than the inner diameter of the cylindrical portion 23 of the main body 20, so that the dust collecting mesh filter B and the dust collecting mesh filter B are When the dust collecting mesh filter B is clogged between the cylindrical portion 23 of the main body 20 and the dust collecting mesh filter B, the hot water filtered by the suspended matter collecting mesh filter A is directly sucked into the upper portion. A bypass flow path C that flows to the port 9 is formed.

The lid 14 is composed of a disc-shaped main body portion 14a and a gripping piece 14b protruding from the front surface side of the main body portion 14a.

The cover body 6 attached to the bathtub side of the filter device 5 thus attached to the suction port 4 is formed in a substantially U-shape in vertical cross section, and is formed on the upper portion of the front portion 6a. The water level indicator 30 is formed, and at the lower part of the water level indicator 30, a hole 31 into which the rotary lid holder 10 is fitted is formed, and the cover body 6 is provided. A long and narrow opening 32 is vertically formed on both side portions 6b.

The opening 32 has a length corresponding to a water level that fluctuates due to a person entering or leaving the bathtub.

Further, it is desirable that the water level in the bathtub 1 be set within a range near the water level indicator 30. This is because when the water level in the bathtub 1 is located above the water level indicator 30 and above the opening 32, the filtering effect is significantly reduced.

Next, a procedure for attaching the filtration device according to the above embodiment will be described.

First, the end portion of the holder 12 is brought into contact with the back surface side of the suction port 4 of the bath 1, and then the fixed body 11 is inserted into the suction port 4 from the inside of the bath tank 1 and the fixed body 11 is inserted. Is rotated in one direction to screw the male screw 24 of the fixed body 11 with the female screw 25 of the holder 12, and the fixed body 11 firmly fixes the holder 12 to the back surface side of the bath 1.

Next, the male screw 18 of the rotary lid holder 10 is screwed onto the female screw 22 of the fixed body 11 to fix the rotary lid holder 10 to the fixed body 11.

At this time, since the filter storage body 21 having the dust collecting mesh filter B stored therein is locked and connected to the locking piece portion 17a of the rotary lid holder 10, the assembling work is performed. Thus, the filter housing 21 is inserted and set in the holder 12.

After this work is completed, the lid 14 is fitted into the opening 15 a of the rotary lid holder 10.

In the filtering device thus set, the hot and cold water W near the surface of the bath 1 is sucked through the suction port 4.

The hot and cold water W sucked from the suction port 4 is first passed from the opening 30 and the opening 32 of the cover body 6 to the mesh filter A for collecting the suspended matter through the opening 19 of the rotary lid holder 10. After being collected and filtered by the mesh filter A for collecting suspended matter, dust and debris floating on the surface of the hot water, the filtered hot water W is used for collecting the dust. After flowing into the mesh filter B, the dust collecting mesh filter B collects and filters the fine dust in the hot and cold water W filtered by the suspended matter collecting mesh filter A, It flows into the holder 12 and is pumped again by the pump P from the discharge port 7 into the bath 1. Of course, at this time, a part of the hot and cold water W filtered by the above-mentioned floating material collecting mesh filter A flows through the bypass flow path C.

When the dust collecting mesh filter B is clogged, the hot water filtered by the floating matter collecting mesh filter A passes through the holder 12 as it is from the bypass channel C. It flows to the suction port 9.

Next, a case will be described in which the floating material collecting mesh filter A and the dust collecting mesh filter B of the filtration device set as described above are replaced and washed.

When replacing the mesh filter A for collecting the suspended matter and the mesh filter B for collecting the dust, by rotating the rotary lid holder 10 in a direction opposite to the tightening direction, Since the collection mesh filter A and the dust collection mesh filter B can be pulled out inward of the bathtub 1 together with the lid 14 and the rotary lid holder 10, they are collected by the suspended matter collection mesh filter A. It is possible to easily wash or replace the dust that has been filtered by the debris, the hot water and the dust collecting mesh filter B.

In the above-described embodiment, the case where the vertically long openings 32 are opened on both sides of the cover body 6 has been described as an example. However, the present invention is not limited to this, and whichever is used. Of course, only one of them may be opened and configured.
