Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an enlarged vertical cross-sectional configuration view of the circulation port member 2 of the present embodiment in an attached state, and FIGS. 2 and 3 are perspective configuration diagrams of a main part of the circulation port member 2.

In the drawing, a circulation port member 2 penetrating and attached to a bathtub wall 1a of a bathtub 1 is provided with a main body central passage portion 10 in a central portion in a cylindrical shape. And is formed integrally between the rear frame portion 12 and
A wire mesh 13 is fixed to the outer peripheral side of the main body central passage portion 10 between the front frame portion 11 and the rear frame portion 12 in a state where a gap is formed, and outside the wire mesh 13, the front frame portion 11 and the rear frame portion 12 are fixed. A support shaft 14 is provided in a bridging manner between the support shafts.
The right guide 15 and the left guide 1 can be opened and closed left and right around the axis
6 are provided.

The right guide 15 and the left guide 16 are connected by connecting frames 18 and 18, respectively, having semicircular frames 17 and 17 at the front and rear, respectively.
9 is provided, and as shown in FIG.
With the right guide 15 and the left guide 16 opened, the filter 3 is attached to the outer periphery of the wire mesh 13 in a wound form from the outside, and in this state, the right guide 15 and the left guide 16 are closed. The filter 3 is configured so that it can be fitted and fixed between the front frame portion 11 and the rear frame portion 12 via the locking projections 20, 20. When the filter 3 becomes dirty, the right guide 15 and the left guide 16 are opened around the support shaft 14 so that the filter 3 can be easily replaced with a new filter. The right guide 15 and the left guide 16 are made of a material containing titanium oxide.

As described above, the filter 3 is provided around the outer periphery of the wire mesh 13.
1, the main body outer peripheral portion 21 is inserted from the inside to the outside of the bathtub wall 1a, and the nut member 23 is inserted from the outside of the bathtub wall 1a with the packing 22 interposed therebetween, as shown in FIG. Is fastened to the outer peripheral portion 21 of the main body, the circulation port member 2 is attached and fixed to the bathtub wall 1a, and a cover 26 is mounted inside the outer peripheral portion 21 of the main body. Since it does not exist, the projecting dimension a of the cover 26 from the bathtub wall 1a to the inside can be made smaller than before,
Therefore, the protrusion toward the inside becomes smaller than before, and the appearance in the bathtub becomes better.

In this embodiment, the filter 3 is arranged inside the circulation port member 2 so as to face outside the bathtub wall 1a.
When bathtub water is sucked from the suction port 2a, the bathtub water passes through guides 15 and 16 as shown by arrows, and dirt and dust are removed by the filter 3, and further passes through the wire net 13 to circulate the cleaning equipment. 5, is sterilized by a sterilizing device 6 in the circulation path 5, and is again returned to the main body central passage 1.
It is returned to 0 and discharged from the discharge port 2b into the bathtub.

In this embodiment, a transparent window 24 is provided on the outer periphery of the guides 15 and 16, for example, a part of the nut member 23, and a purple LED 25 is arranged outside the transparent window 24. The LED 25 is capable of emitting violet light having a wavelength of 400 nm or less, and has a violet LE
By irradiating the guides 15 and 16 containing titanium oxide with the ultraviolet light emitted from D25, it is configured such that bacterial growth can be suppressed by a photocatalytic effect.
Therefore, the possibility that the dirt captured by the filter 3 is putrefied and the bath water is contaminated by bacterial growth is reduced. In addition, since the right guide 15 and the left guide 16 can be easily cleaned when the filter 3 is replaced, even if dirt is deposited on the titanium oxide, it can be cleaned and removed satisfactorily. Reduction can be prevented well.

In order to turn on the purple LED 25, for example, as shown in FIG. 5, a power generator 27 is provided in the circulation path 5 of the purification device 4, and the power generator 27 passes through the circulation path 5. The impeller can be rotated by the flow of hot and cold water to generate power. The power generated by the power generation device 27 can be supplied to the purple LED 25 and turned on, and the purification device 4 is operated. When the power is generated by the power generation device 27,
From 5, it becomes possible to suppress the growth of bacteria by irradiating the guides 15 and 16 with ultraviolet rays. Furthermore, the bathtub wall 1a
The Peltier device 28 may be provided in a portion where the temperature difference is large, such as outside the Peltier device, and the purple LED 25 may be turned on by the Peltier electromotive force generated by the Peltier device 28.

FIG. 4 shows a structure in which the right guide 15 and the left guide 16 are completely divided so that they can be removed. That is, in the configuration of FIG. 4, the filter 3 is wound around the outer periphery of the wire mesh 13 and the right guide 15 and the left guide 16 are pressed against the filter 3 from the outside thereof so that the front frame 11 and the rear frame 12 When the filter 3 is replaced, the right guide 15 and the left guide 16 can be removed to the outside, and when the filter 3 is replaced, the right guide 15 and the left guide 16 can be simultaneously removed. It can be cleaned.

[0012]

According to the present invention, there is provided a circulation port member provided with a filter which is attached to a bathtub wall with a cover inside, wherein the filter is provided so as to face the outside of the bathtub wall, and the cover projects into the bathtub. By setting the dimensions small, the protrusion of the cover portion to the inside of the bathtub becomes extremely smaller than before, and this has the effect of improving the appearance of the installed state.

In addition, a guide containing titanium oxide which can replaceably fix the filter is provided.
By providing a violet LED capable of irradiating violet light having a wavelength of 00 nm or less, the filter can be satisfactorily fixed by the guide, and the filter can be satisfactorily replaced by removing the guide. In addition, when the light from the purple LED is irradiated on the guide, the growth of bacteria is favorably suppressed by the photocatalytic effect, and the bathtub can be kept clean without contaminating the water.

[0014] Further, since the purple LED is turned on by electric power from a power generation device provided in a circulation path connected to the circulation port and / or a Peltier element attached to a bathtub wall or the like, a power supply is separately provided. Thus, the purple LED can be satisfactorily lit by the power from the power generation device or the Peltier element, and a power saving effect can be obtained, and wiring and the like can be completed in the bathroom.
