BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0019]
1 to 5 show one embodiment of the present invention.
[0020]
As shown in FIG. 1, a set of a circulation port filter 30 for removing dust and dirt from the hot water drawn from the bathtub and a filter base 20 to which the filter base 20 is attached are shown on the hot water suction side 10A of the hot water circulation port of the bathtub. Of the upper and lower hot water circulation ports 10A and 10B, the upper hot water circulation port 10A is used as the hot water suction side because the natural circulation type bath pot attached to the bathtub is replaced with a forced circulation type bath pot, and two hot water circulation units are used. This is because it may be advantageous when both the mouths 10A and 10B are used. When a natural circulation bathtub with a pump is attached, hot water is usually sucked in from the lower hot water circulation port 10B, but in that case, it may be attached to the lower hot water circulation port 10B.
[0021]
The filter base 20 is integrally formed of, for example, a synthetic resin, and has a circumferential portion 21 having an outer diameter larger than that of the hot water circulation port 10A. On one side of the circumference 21, there is formed a projection 23 which can be fitted to the circulation port filter 30. On the other side of the circumferential portion 21, an insertion portion 22 attachable to the hot water circulation port 10A is formed. The filter base 20 has an opening 24 that penetrates the center to allow warm water sucked from the bathtub to pass therethrough.
[0022]
As shown in FIG. 2, the circulation port filter 30 is a substantially cylindrical cylinder having an open part 31 at one end facing the hot water circulation port 10 </ b> A and a bottom part 32 at the other end.
[0023]
As shown in FIG. 5, the inner diameter of the cylindrical body is substantially equal to or larger than the outer diameter of the peripheral portion 11 of the hot water circulation port 10A.
[0024]
A plurality of hot water inlets F which are cut out to suck hot water in the bathtub are formed on the side and bottom of the cylindrical body. A filter member (not shown) for filtering dust and the like in hot and cold water is attached to the inside of the cylindrical body, and at least the hot water suction port F is covered by the filter member from the inside. In order to prevent hot water from being disturbed due to the attachment of large debris to the hot water inlet F, a net-like portion is integrally formed between the filter member and the outside, or is separately formed of metal or the like. You may attach the one you made.
[0025]
A claw 33 projecting parallel to the axial direction of the cylindrical body is formed on the periphery of the open end 31 of the cylindrical body. The claw 33 is slidable in a guide groove (not shown) formed in the circumferential portion 21 inside the convex portion 23 of the filter base 20, and is provided with a notch for preventing the filter base 20 from falling off when mounted on the filter base 20. 33A are formed. In the guide groove of the filter base 20, a fitting portion (not shown) that fits into the cut 33A is formed.
[0026]
The claw 33 may be a projection facing outward of the cylindrical body. In this case, instead of the above-described guide groove, a protruding band protruding inward from the convex portion 23 of the filter base 20 may be formed at an interval slightly larger than the thickness of the claw 33 from the circumferential portion 21.
[0027]
A screw S is attached to the center of the bottom 32 inside the cylinder. As shown in FIGS. 3 and 4, the screw S is longer than the length of the cylinder. As shown in FIG. 5, the screw S is for directly attaching to the water stopper attachment part 40 when the water stopper attachment part 40 is provided in the circulation port 10A. One end of the water stopper mounting portion 40 penetrates the bathtub B, and is fitted inside a connecting pipe P connected to the outside of the bathtub B. The other end has a portion to which a water stop is attached, which is located inside the bathtub B and is located at the center of a portion provided so as to cross the circulation port 10A as shown in FIG. A screw hole 41 to be screwed with the screw is formed. The screw S of the circulation port filter 30 can be screwed with the screw hole 41.
[0028]
Next, the operation will be described.
[0029]
The circulation port filter 30 is mounted on the hot water circulation ports 10A and 10B of the bathtub on the side of the hot water suction side. Some of the hot water circulation ports 10A and 10B have a water stopper for attaching a water stopper to a side where hot water is discharged when used as a natural circulation bath (usually a lower circulation port). . FIG. 1 shows a case where the hot water circulating port 10A to which the circulating port filter 30 is attached is not provided with the hot water fixing portion 40 or the like. In this case, the filter base 20 is first mounted directly on the hot water circulation port 10A. The filter base 20 can be attached by inserting the insertion portion 22 into the hot water circulation port 10A.
[0030]
Next, the circulation port filter 30 is attached to the filter base 20 attached to the hot water circulation port 10A. The claw 33 of the circulation port filter 30 may be twisted until it stops to the right according to a guide groove (not shown) formed in the circumferential portion 21 inside the projection 23 of the filter base 20. At this time, the cut 33A is fitted to the fitting portion, so that the circulation port filter 30 does not fall off from the filter base 20. Since the screw S of the circulation port filter 30 passes through the opening 24 provided at the center of the filter base 20, it does not hinder the mounting operation.
[0031]
When removing the circulation port filter 30 for cleaning or replacement, the filter 30 may be turned to the left as opposed to the case where the notch 33A and the fitting portion are fitted until the fitted state is eliminated.
[0032]
When the circulation port filter 30 is attached to the hot water circulation port 10A on the hot water suction side in this way, the hot water in the bathtub is sucked only through the hot water suction port F provided on the side and bottom of the circulation port filter 30, and garbage is removed. Is removed by a filter member attached to the inside of the circulation port filter 30. In the case where a net-shaped portion is provided in the hot-water inlet F, large dusts and the like are applied to the net-shaped portion, so that the dusts and the like can be prevented from covering the filter member and affecting the hot-water suction. Thus, in the circuit from the hot water circulation port 10A on the hot water suction side to the hot water circulation port 10B on the hot water discharge side via the bath kettle, adhesion of dust and dirt is significantly reduced.
[0033]
The circulation port filter 30 can be easily removed with the filter base 20 attached to the hot water circulation port 10A, so that the circulation port filter 30 can be cleaned or replaced very easily.
[0034]
When the hot water circulating port 10A is provided with the hot water fixing portion 40, the hot water mounting portion 40 is in the way and the filter base 20 cannot be interposed, so that the circulation port filter 30 is directly mounted to the hot water mounting portion 40. .
[0035]
As shown in FIG. 5 and FIG. 7 showing the prior art, the water stopper mounting portion 40 is provided with a screw hole which is screwed with a screw provided on the water stopper at a portion crossing the hot water circulation port 10A. Therefore, the screw S of the circulation port filter 30 may be screwed into the screw hole 41 as shown in FIG. 5 and rotated to the right until the periphery of the opening end 31 of the circulation port filter 30 is in close contact with the bathtub. When removing the filter, the circulation port filter 30 may be turned in a direction opposite to the direction in which the filter is simply attached. Although the hot water circulation port 10A provided with the hot water fixing portion 40 is very easily attached and detached, the attached state can be very strong.
[0036]
In this embodiment, the use of the circulation port filter 30 in combination with the filter base 20 and the use of the circulation port filter 30 alone are enabled.
[0037]
Thereby, it has wide versatility and can be easily attached regardless of the type of hot water circulation port.
[0038]
In the above-described embodiment, the circulation port filter 30 is shown as a substantially cylindrical cylinder, but is not limited thereto and may be a hemisphere or any shape.
[0039]
FIG. 8 shows an example of a conventional bath stopper. That is, the mortar 14 is screwed with the screws 16, 16 so that the mounting screw holes 15 a, 15 a formed in the mortar and the mounting screw holes 15 b, 15 b formed in the circulation port 19 are aligned.
[0040]
In such a case, the fixture A shown in FIG. 9 may be used. That is, the stopper 14 is removed, and a screw hole 18 for screwing the mounting screw S of the circulation port filter 30 shown in FIG. 17 and 17 are screwed together with mounting screw holes 15b, 15b formed in the circulation port 19, and the mounting screw S of the circulation port filter 30 is screwed into the screw hole 18 and mounted.
[0041]
