There is something configured as follows.
JP 2003-102633 A

  In conventional circulation fittings, a filter or the like is provided inside and the water channel is blocked, so it is difficult to drain the water remaining in the piping outside the bathtub well into the bathtub. In order to drain water, it may be possible to make the filter's eyes coarse so that the remaining water can be drained. There is a problem that it becomes difficult to capture the trash, and garbage etc. flows out to the washing machine side.

The present invention has been devised in view of the above-described conventional problems, and it is possible to satisfactorily capture the waste of bathtub water and to drain the residual water in the path outside the bathtub well into the bathtub. The claim 1 is a water inlet flange member that is fixed to the opening of the inner wall of the bathtub and is formed with a water passage that communicates the inside and outside of the bathtub. The water inlet flange member includes a movable filter that closes the water channel by water pressure when the water in the bathtub is sucked out of the bathtub, and is movable to a position where the water channel is opened except when the water is sucked. The water in the bathtub passes through the movable filter and flows out of the bathtub, and the remaining water outside the bathtub is drained into the bathtub through the water channel except at the time of suction.
Moreover, the water channel is formed in the guide surface in the water inlet flange member which the outer periphery of the said movable filter slidably contacts.

The water inlet flange member of the present invention is provided with a movable filter that closes the water channel by water pressure when the water in the bathtub is sucked out of the bathtub, and is movable to a position where the water channel is opened except when the water is sucked. When the water inside is sucked into a washing machine or the like outside the bathtub, the water channel in the water inlet flange member is blocked by the filter, and the waste water in the bathtub is well captured by the filter.
In addition, since the filter is moved to a position where the water channel is opened at times other than during suction, the residual water remaining outside the bathtub is well drained into the bathtub through the water channel of the water inlet flange member. Therefore, the remaining water does not rot in the path and can be kept hygienic.

  In addition, since the water channel is formed on the guide surface in the water inlet flange member where the outer periphery of the movable filter is in sliding contact, the water channel is integrated with the guide surface in which the filter is in sliding contact. Even if it is made small, the water channel can be secured satisfactorily, and a compact water inlet flange member can be obtained.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective configuration diagram of a bathroom and a washroom. A water inlet 4 is fixedly provided on a rising inner wall 2a on the washing room 3 side of a bathtub 2 installed in the bathroom 1, and the water inlet 4 Is connected to an inclined bathroom pipe 5 passing through the inside of the apron, and the nipple 16 at the tip of the bathroom pipe 5 is connected to the through metal fitting 6 from the outside of the wall panel 17 as shown in FIG. After being joined, a pipe 7 outside the bathroom is piped up to the wall of the washroom 8 from the through metal fitting 6, and a water supply elbow 9 connected to the pipe 7 outside the bathroom is provided on the wall inside the washroom 8. ing.
A water supply hose 10 having a washing machine connection elbow 10a at the tip thereof is connected to the water supply elbow 9, and the water supply elbow 9 can be connected to the washing machine 11 installed in the wash room 8 via the water supply hose 10. Only by connecting the water supply hose 10 on the side, the remaining hot water in the bathtub 2 can be satisfactorily introduced into the washing machine 11 by operating the pump built in the washing machine 11.

  As shown in FIG. 2, the water inlet 4 has a flange member 14 inserted into the opening 12 penetrating the rising inner wall 2a of the bathtub with a flat packing 13 and a triangular packing 13a interposed from the front and back sides. An elbow 15 connected to the pipe 5 in the bathroom is connected to the flange member 14 from the outside of the bathtub, and the flange member 14 is fixed to the rising inner wall 2a. In the flange member 14, a sponge-like filter is provided. 18 is accommodated, and a cover 19 is screwed and covered.

3 shows an external view of the water inlet 4, and FIG. 4 shows a cross-sectional configuration diagram of the water inlet 4.
That is, the flange member 14 is formed in a cylindrical shape, and a flange portion 14a is protruded on the inner side of the bathtub. The male screw formed on the outer periphery of the flange portion 14a is formed on the inner periphery of the cover 19. A cover 19 can be attached to the flange member 14 by screwing a female screw, and a storage space in which the filter 18 can be stored is formed in the flange member 14.

FIG. 4 shows a state where the cover 19 is removed.
The filter 18 is fixedly provided with a sliding plate 21 penetrating a plurality of small holes 21a, 21a. The outer periphery of the sliding plate 21 and the outer periphery of the filter 18 form an inner diameter surface of the flange member 14. The filter 18 and the sliding plate 21 are configured to be slidably moved along the guide surface 14b in sliding contact with the guide surface 14b.

  Further, on the outer peripheral side of the guide surface 14b, as shown in the plan view of FIG. 5, two water channels 20, 20 on the left and right are formed in parallel with the guide surface 14b and are opened inside the bathtub, respectively. The front end of the water channel 20 is bent at a right angle inside the flange member 14 to form a right water channel 20a. The right water channel 20a passes through the guide surface 14b and is opened inside the flange member 14. Moreover, the bottom part 14c which formed several through-holes 14d and 14d is integrated in the bathtub outer side of the flange member 14. As shown in FIG.

In this example, a spring 22 is provided between the bottom 14c of the flange member 14 and the sliding plate 21 of the filter 18, and the urging force of the spring 22 always makes the bathtub of the right-angle water channel 20a as shown in FIG. The filter 18 and the sliding plate 21 are located inside, and the right-angle water channel 20a is in an open state.
Therefore, in this state of FIG. 4, the residual water in the bathroom pipe 5 passes through the elbow 15 along the slope of the bathroom pipe 5 and enters the flange member 14 from the through hole 14d of the flange member 14, and enters the right angle water channel. Since the water will be drained from 20a through the water channel 20 into the bathtub 2, and the remaining water will not remain in the pipe 5 in the bathroom. It can be held.

  On the other hand, when the pump in the washing machine 11 is operated and the water in the bathtub 2 is sucked into the washing machine 11 to be reused, the bathtub water is caused to be flanged by the suction force of the pump of the washing machine 11. If water pressure acts when sucked into the water channel 20, the water pressure overcomes the urging force of the spring 22, and the filter 18 and the sliding plate 21 move outward along the guide surface 14 b by the water pressure, so that the filter 18 is moved. It is moved to a position where the right-angle water channel 20a is blocked, and the state shown in FIG. 6 is obtained.

  In the state of FIG. 6, all the bathtub water passes through the filter 18 from the water channel 20, is discharged from the small hole 21a of the sliding plate 21, and further passes through the through holes 14d and 14d of the bottom portion 14c of the flange member 14, Through the elbow 5, the bathroom pipe 5, the bathroom pipe 7 and the water absorption hose 10 are introduced into the washing machine 11, and in this case, all of the bath water passes through the filter 18, The filter 18 captures the dust in the bathtub water well, and the dust does not enter the washing machine 11.

Note that FIGS. 7, 8, and 9 show modified examples.
In the modified example, the water channel 20 is integrally formed on the guide surface 14 b of the flange member 14.
That is, as shown in the plan view of FIG. 8, a plurality of water channels 20, 20, 20 are integrally formed at a predetermined interval by being recessed from the guide surface 14 b outward in a substantially semicircular shape. The outer periphery of the filter 18 and the sliding plate 21 is in sliding contact with the guide surface 14b on which the filter 20 and the sliding plate 21 are formed, and the filter 18 and the sliding plate 21 can be slid along the guide surface 14b. Yes.
Other configurations are almost the same as those shown in FIG. 4, FIG. 5, and FIG.

  FIG. 7 shows a normal state other than the time of suction. In this state, the sliding plate 21 and the filter 18 are urged toward the inside of the bathtub by the urging force of the spring 22, and downstream of each water channel 20. The right-angle water channel 20a at the end is in an open state, and the residual water in the bathroom pipe 5 enters the flange member 14 through the through hole 14d at the bottom, and passes through the water channel 20 from the right-angle water channel 20a. It is drained into the interior, so that the remaining water is drained smoothly and can be kept hygienic without any residual water.

  In addition, when the washing machine 11 is actuated and the bathtub water in the bathtub 2 is sucked by the pump of the washing machine 11, the water pressure acts and the water pressure exceeds the urging force of the spring 22, thereby sliding. The plate 21 and the filter 18 move to the position shown in FIG. 9, and the filter 18 closes the right-angle water channel 20a of each water channel 20. In this state, the bath water sucked into the flange member 14 through each water channel 20 is All the dust is removed well through the filter 18, and the bathtub water without dust is satisfactorily introduced into the washing machine 11 and reused.
