  By the way, considering only the drainage capacity, it is preferable that the drainage amount per unit time from the tank body is large. However, in some cases, it may be desired to adjust the amount of drainage per unit time from the tank at the site of use or the like.

  For example, two drain outlets are provided in the tank body, and one drain trap is provided corresponding to each drain outlet, while drainage that has passed through each drain outlet and drain trap flows into one pipe. This is the case.

  In this case, if the amount of drainage is relatively large, a large amount of drainage flows into the pipe, and a large amount of drainage is filled in the pipe (with no space in the upper part of the pipe). It becomes easy. If a large amount of drainage flows in the pipe, the sealed water in the drain trap is also drawn to the pipe due to the effect of atmospheric pressure, and as a result, the sealed water disappears (out of the sealed water) May occur).

  On the other hand, if the amount of drainage is relatively small, it becomes difficult for the seal to run out, but drainage capacity becomes insufficient and drainage takes time. As a result, for example, when bathing is continuously performed in a care facility or the like, there is a possibility that trouble may occur.

  Accordingly, it is desirable that the amount of drainage can be appropriately adjusted at the site of use or the like from the viewpoint of making the amount of drainage appropriate so that good drainage performance can be maintained while preventing sealing water from running out.

  Of course, not only the case illustrated above but also the configuration capable of adjusting the amount of drainage can improve convenience in various cases.

And with the displacement of the said operation part, the transmission shaft 9 moves up and down with respect to the bathtub 100 by reciprocatingly moving in the inner periphery of the outer tube 10 provided in the outer periphery. Yes. Specifically, when the transmission member 9 moves forward due to the displacement of the operation portion, the support shaft 42 is pushed up by the transmission member 9 and moves up to a predetermined upper position with respect to the bathtub 100. On the other hand, in this state, when the transmission member 9 moves backward due to the displacement of the operation portion, the support shaft 42 moves downward due to its own weight or the like.

  Further, in this embodiment, every time the operation unit is operated, the support shaft 42 is locked at the upper position by a predetermined lock mechanism (for example, a thrust lock mechanism) (not shown), and the support shaft 42 is under unlocking. The movement is performed alternately.

  The plug lid 5 has an umbrella-shaped portion 51 whose surface appears on the surface of the bathtub 100, a mounted portion 52 provided in the center of the back surface of the umbrella-shaped portion 51, and a slide positioned outside the mounted portion 52. A portion 53 and a packing portion 54 located outside the slide portion 53 are provided.

  The umbrella-shaped portion 51 is formed in a disk shape, and its surface is covered with a thin covering portion made of stainless steel or the like in order to improve the appearance quality.

When the support shaft 42 is disposed at the upper position, as shown in FIG. 2, the packing portion 54 is separated from the drain port member 2, and drainage is possible. On the other hand, when the support shaft 42 moves downward, the entire periphery of the outer peripheral edge of the packing portion 54 contacts the drain port member 2, thereby closing the drain port 102 and allowing water to be stored in the bathtub 100 (see FIG. 1). ).

  The hair catcher 6 is placed on the outer ring portion 31 and is disposed in a flow path for drainage from the bathtub 100. As shown in FIGS. 3 and 4, the hair catcher 6 includes a main body portion 61, a restriction portion 62, and a reference portion 63. 3 is a view of the hair catcher 6 as viewed from the front side (upstream side in the direction of drainage flow), and FIG. 4 is a view of the hair catcher 6 as viewed from the back side (downstream side in the direction of drainage flow).

  As shown in FIG. 5, the main body 61 is made of resin or the like, and has a cylindrical inner cylinder 61A extending in the central axis direction and a cylindrical (annular) outer cylinder extending in the central axis direction. 61B and the rib part 61C which connects the inner cylinder part 61A and the outer cylinder part 61B are provided.

  61 A of inner cylinder parts are arrange | positioned substantially coaxially with the slide part 53 in the outer periphery of the slide part 53 (refer FIG. 1, 2). Further, the inner cylinder portion 61A is provided with a plurality of protrusions 61D extending in the central axis direction at equal intervals along the circumferential direction on the inner periphery thereof. Due to the presence of the protruding portion 61D, the relative movement of the inner cylindrical portion 61A along the radial direction with respect to the slide portion 53 is restricted, and a wide range of the inner peripheral surface of the inner cylindrical portion 61A extends from the inner peripheral surface of the slide portion 53 It is in a slightly separated state. This prevents the inner cylinder part 61A and the slide part 53 from coming into close contact with each other, and when the stopper lid 5 moves upward, that is, when the drainage port 102 is opened, the inner cylinder part 61A and thus the hair catcher 6 together with the slide part 53. Can be prevented from moving up.

  The outer cylinder portion 61B is provided coaxially with the inner cylinder portion 61A outside the inner cylinder portion 61A, and the entire circumference of the lower end surface thereof is placed on the outer ring portion 31. As described above, since the hair catcher 6 can be prevented from moving up due to the movement of the stopper lid 5, the lower end surface of the outer cylinder portion 61 </ b> B is always maintained in a state of being placed on the outer ring portion 31. The Rukoto. Thereby, the outflow of the foreign material which passed between the hair catcher 6 (outer cylinder part 61B) and the attachment member 3 (outer ring part 31) can be prevented more reliably, and the foreign material is more reliably collected by the hair catcher 6. It can be done.

  The rib part 61C protrudes from the outer periphery of the inner cylinder part 61A and is connected to the inner periphery of the outer cylinder part 61B, and extends radially from the central axis of the main body part 61. A plurality of rib portions 61C are provided at equal intervals along the circumferential direction of the central axis, and a gap for water passage is formed between the adjacent rib portions 61C.

  Returning to FIG. 3, the restricting portion 62 has a thin plate shape made of a predetermined metal (for example, stainless steel), and on the front side of the main body portion 61, its own central axis coincides with the central axis of the main body portion 61. And overlapped with the main body 61. Further, the restricting portion 62 is rotatable relative to the main body portion 61 with the central axis as a rotation axis.

  As shown in FIG. 6, the restricting portion 62 includes an annular inner ring portion 62A whose center is located on the central axis thereof, and an annular outer ring portion provided coaxially with the outer ring portion 62A. 62B and an arm portion 62C as a flow rate adjusting means for connecting the inner ring portion 62A and the outer ring portion 62B.

  The inner ring portion 62A is disposed on the outer periphery of the inner cylinder portion 61A, and the entire inner peripheral surface thereof is in close contact with or substantially in close contact with the outer peripheral surface of the inner cylinder portion 61A. Further, on the inner periphery of the inner ring portion 62A, there are a plurality of convex portions that protrude extremely minutely inward in the radial direction at equal intervals along the circumferential direction. And the inner cylinder part 61A is press-fitted into the inner periphery of the inner ring part 62A, so that a force is applied from the inner cylinder part 61A to the inner ring part 62A. As a result, as described above, although the restricting portion 62 can rotate relative to the main body portion 61, relative rotation of the restricting portion 62 due to the influence of drainage or the like is extremely difficult to occur.

  The outer ring portion 62B is located on the inner periphery of the outer cylinder portion 61B, and the entire outer peripheral surface thereof is in a state of being in close proximity (substantially in contact) with the inner peripheral surface of the outer cylinder portion 61B. .

  The arm portion 62C protrudes from the outer periphery of the inner ring portion 62A and is connected to the inner periphery of the outer ring portion 62B, and extends radially from the central axis of the restricting portion 62. The arm portions 62C are provided in the same number as the rib portions 61C at equal intervals along the circumferential direction of the central axis, and a water passage gap is formed between the adjacent arm portions 62C. In the present embodiment, as described above, the entire inner peripheral surface of the inner ring portion 62A is in close contact with the outer peripheral surface of the inner cylindrical portion 61A, and the entire outer peripheral surface of the outer ring portion 62B is the outer cylindrical portion 61B. Therefore, the drainage passes through the restricting portion 62 through only the gap between the arm portions 62C.

  Further, the width of the arm portion 62C along the circumferential direction of the central axis of the restricting portion 62 is set to be smaller than the width of the gap for water passage formed between the rib portions 61C.

  In the present embodiment, the collection part 67 that is a part of the hair catcher 6 that mainly collects foreign substances contained in the waste water is constituted by the rib part 61C of the main body part 61 and the arm part 62C of the restriction part 62. (See FIG. 3).

  Returning to FIG. 4, the reference portion 63 has a thin plate shape made of a predetermined metal (for example, stainless steel or the like). 2, the center axis of the main body 61 is overlapped with the main body 61 in a state where the center axis thereof coincides with the central axis of the main body 61.

  The reference portion 63 includes a reference arm portion 63C that extends radially from the central axis and is provided at the same interval as the arm portion 62C. In this embodiment, the reference portion 63 and the restriction portion 62 have substantially the same shape. Has been. On the other hand, the restricting portion 62 is rotatable relative to the main body portion 61, but the reference portion 63 is fixed to the main body portion 61 and is not rotatable relative to the main body portion 61.

  In the present embodiment, the reference arm portion 63C is visible from the front side of the hair catcher 6 through the gap between the arm portions 62C and the gap between the rib portions 61C. Then, from the front side of the hair catcher 6, it is possible to grasp the shift amount of the arm portion 62 </ b> C with respect to the reference arm portion 63 </ b> C along the circumferential direction of the restricting portion 62.

  Now, in the hair catcher 6 described above, with the stopper lid 5 removed from the support shaft 42, the restricting portion 62 is relatively rotated with respect to the main body portion 61, and the gap for water passage formed between the rib portions 61C. By adjusting the overlapping area along the central axis direction of the main body portion 61 of the arm portion 62C, the water flow rate in the hair catcher 6 can be adjusted.

  For example, when the arm portion 62C overlaps each of the rib portions 61C and the overlapping area is minimized, the water flow rate can be maximized.

  On the other hand, when the arm portion 62C overlaps with each of the gaps for water flow to the maximum and the overlap area is maximized, the water flow rate can be minimized. However, as described above, since the width of the arm portion 62C is smaller than the width of the gap for water flow, even when the overlapping area is maximized, the gap for water flow includes the main body. A region that does not overlap with the arm portion 62 </ b> C exists along the central axis direction of the portion 61.

  The adjustment of the water flow rate may be performed with the hair catcher 6 placed on the outer ring portion 31 or may be performed after the hair catcher 6 is removed.

  As described in detail above, according to this embodiment, the amount of drainage per unit time from the bathtub 100 is adjusted by rotating the regulating portion 62 relative to the main body portion 61 and adjusting the water flow rate in the hair catcher 6. Can be adjusted. Therefore, it is possible to appropriately adjust the amount of drainage at the site of use, and excellent convenience can be obtained.

  In particular, in the present embodiment, the flow rate of water and thus the amount of drainage can be adjusted by a very simple method of rotating the regulating part 62 relative to the main body part 61. Therefore, the operation of adjusting the amount of drainage at the site of use can be performed more easily, and workability can be improved.

  Moreover, compared with the case where a mechanism for adjusting the flow rate is provided separately from the hair catcher 6, the number of parts can be reduced and the apparatus can be simplified. Further, the flow rate adjusting means is realized by a relatively simple portion such as the arm portion 62C. As a result, it is possible to effectively improve productivity and reduce costs.

  Further, even when the overlapping area is maximized, the drainage is likely to flow to some extent through the gap for water passage formed between the rib portions 61C. Therefore, even if the restricting portion 62 is relatively rotated due to the influence of drainage or the like and the overlapping area is maximized, the drainage capacity is easily secured to some extent. As a result, the situation where drainage becomes impossible can be prevented more reliably.

  In addition, in this embodiment, since the force is applied from the inner cylindrical portion 61A to the inner ring portion 62A, the regulating portion 62 easily rotates relative to the main body portion 61 due to the influence of drainage or the like. Can be more reliably prevented. As a result, unintended fluctuations in the water flow rate can be effectively suppressed.

  In addition, the number of the rib portions 61C and the arm portions 62C are the same, and are provided at equal intervals along the circumferential direction. Therefore, the arm portion 62C can be overlapped with each of the water passage gaps formed between the rib portions 61C, and the water flow rate can be made smaller. Moreover, it can be set as the state which accumulated the arm part 62C with respect to each of the rib part 61C, and can make a water flow volume larger. That is, according to this embodiment, the adjustment range of the water flow rate can be sufficiently increased. As a result, the degree of freedom for adjusting the water flow rate can be increased. Further, when the flow rate is adjusted by rotating the regulating portion 62, it can be changed continuously (stable). Therefore, the ease of flow rate adjustment can be improved.

  Moreover, it becomes easy to objectively determine the degree of the water flow rate based on the amount of shift of the arm portion 62C with respect to the reference arm portion 63C along the circumferential direction of the restricting portion 62. As a result, the water flow rate can be adjusted more easily.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, water can be passed between the adjacent arm portions 62C. However, FIG. 7 and FIG. 8 (FIG. 8 is a restriction in the region RK surrounded by the dotted line in FIG. It is good also as providing the obstruction | occlusion part 62D which makes water impossible between adjacent arm parts 62C, as shown in the partially broken expansion perspective view of the part 621). In this case, the reference flow rate can be reduced while maintaining the state in which the water flow rate changes continuously (stable) when the regulating unit 621 is rotated.

  The blocking part 62D may be such that its surface is flush with the surface of the adjacent arm part 62C. That is, as shown in FIG. 9, a plate-like portion 62E having a flush surface may be formed by the blocking portion 62D and the arm portion 62C. In this case, the width W1 of the plate-like portion 62E along the circumferential direction of the restricting portion 621 is equal to one of the widths W2 from one arm portion 62C to the other arm portion 62C along the circumferential direction of the restricting portion 621. If it is, it can be said that the closed portion 62D is provided between the adjacent arm portions 62C.

  Further, the blocking portion 62D does not necessarily have to be adjacent to each other with the arm portion 62C interposed therebetween. For example, a gap formed between the arm portions 62C exists between the two blocking portions 62D. Also good.

  In addition, the blocking part 62D is not provided, and the restriction part 62 capable of passing water between all adjacent arm parts 62C and the blocking part 62D are provided, and between the adjacent arm parts 62C. It is also possible to prepare a restricting portion 621 that is partially incapable of passing water and make it possible to select a restricting portion to be used or to replace the restricting portion. In this case, compared with the case where only one regulating part is used, the adjustment range of the water flow rate can be further increased, and the degree of freedom related to the adjustment of the water flow rate can be further increased.

  (B) In the above embodiment, the reference portion 63 is provided on the opposite side of the restricting portion 62 with the main body portion 61 interposed therebetween, but the reference portion 63 may not be provided.

  Further, in place of the reference portion 63, as shown in FIG. 10, a second restricting portion having a plurality of second arm portions 64 </ b> C extending radially from its own central axis and capable of rotating relative to the main body portion 61. 64 may be provided. And the 2nd control part 64 is rotated relatively with respect to the main-body part 61, and the overlapping area along the central-axis direction of the main-body part 61 of the 2nd arm part 64C with respect to the clearance gap for water passage formed between the rib parts 61C is made. You may comprise so that a water flow volume can be adjusted by adjusting. That is, the flow rate adjusting means may be configured by the arm portions 62C and the second arm portions 64C provided on the front and back of the main body portion 61. In this case, compared with the case where only the arm portion 62C is provided as the flow rate adjusting means, the adjustment range of the water flow rate can be further increased. As a result, the degree of freedom for adjusting the water flow rate can be further increased.

  Moreover, it is good also as applying the structure regarding the control part 62 mentioned above with respect to the 2nd control part 64. FIG. For example, in the 2nd control part 64, it is good also as providing the obstruction | occlusion part which cannot pass between adjacent 2nd arm parts 64C.

  In addition, although the 2nd control part 64 in FIG. 8 is substantially the same shape as the reference | standard part 63, the shape of the 2nd control part 64 is not limited to this. Therefore, the number of the second arm portions 64C does not need to be the same as the number of the rib portions 61C, and the second arm portions 64C do not need to be provided at equal intervals.

  (C) In the above embodiment, a force is applied from the inner cylindrical portion 61A to the inner ring portion 62A, but a force is applied from the inner ring portion 62A to the inner cylindrical portion 61A. You may comprise as follows. Also, by pressing the outer ring part 62B into the inner periphery of the outer cylinder part 61B, a force is applied from one of the outer cylinder part 61B and the outer ring part 62B to the other of the two, You may comprise so that the relative rotation of the control part 62 may not arise easily.

  (D) In the said embodiment, although the bathtub 100 is illustrated as a tank body, the tank body which can apply the technical idea of this invention is not limited to a bathtub. Therefore, for example, the technical idea of the present invention may be applied to a wash basin or a kitchen sink.
