[0001] SUMMARY OF THE DISCLOSURE Aspects of the present invention generally relate to hair catchers. [Background technology]

[0002] Hair catchers that collect hair and other debris that has flowed down a drain on the floor of a washing area are known (Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-165161 A [Patent Document 2] JP 2020-165158 A Summary of the Invention [Problem to be solved by the invention]

[0004] The hair catchers described in Patent Documents 1 and 2 have a main body and a standing wall extending upward from the main body. The standing wall is provided around the periphery of the main body to generate a swirling flow. In such a case, for example, the standing wall may get in the way when cleaning the hair catcher or the drain.

[0005] The present invention has been made based on the recognition of the above problem, and aims to provide a hair catcher that is easy to use. [Means for solving the problem]

[0006] The first invention is a hair catcher comprising a main body portion having a drainage hole and a standing wall portion rising upward from the main body portion, the standing wall portion being softer than the main body portion.

[0007] According to this hair catcher, by making the vertical wall portion soft, it is possible to bend the vertical wall portion or tilt it inward or outward during cleaning. This allows a sponge or brush to reach every corner, improving cleaning performance even if a vertical wall portion is provided. Also, when cleaning the drain outlet in which the hair catcher is installed with the hair catcher installed, even if the hair catcher has a vertical wall portion, a sponge or brush can reach every corner, improving cleaning performance even if a vertical wall portion is provided.

[0008] A second invention is the hair catcher according to the first invention, characterized in that the Shore hardness of the standing wall portion is 30 or more and 70 or less.

[0009] According to this hair catcher, the upright wall portion can provide both a function of guiding water and ease of cleaning.

[0010] A third invention is the hair catcher according to the first or second invention, characterized in that the standing wall portion is formed from a flexible material.

[0011] According to this hair catcher, the upright wall portion can provide both a function of guiding water and ease of cleaning.

[0012] A fourth invention is a hair catcher according to the first or second invention, wherein the standing wall portion has one side end portion located radially inward from the peripheral end portion of the main body portion, a peripheral wall portion extending circumferentially from the one side end portion along the peripheral end portion of the main body portion, and another side end portion located on the tip side of the peripheral wall portion, and the standing wall portion has a thickness that gradually increases from the one side end portion to the other side end portion, or from the other side end portion to the one side end portion.

[0013] According to this hair catcher, the provision of a thicker portion increases the rigidity, and when attaching or detaching the hair catcher, the thicker portion can be pinched with the fingers, thereby improving the ease of use of the hair catcher.

[0014] A fifth invention is a hair catcher according to the first or second invention, characterized in that the main body portion and the standing wall portion are integrally molded by two-color molding.

[0015] This hair catcher can improve durability.

[0016] A sixth invention is a hair catcher according to the first or second invention, characterized in that the standing wall portion has one side end portion located radially inward from the peripheral end portion of the main body portion, a peripheral wall portion extending circumferentially from the one side end portion along the peripheral end portion of the main body portion, and another side end portion located on the tip side of the peripheral wall portion, and the other side end portion has an extension portion extending upward from the peripheral end portion of the main body portion, and a bent portion bent radially outward from the upper end of the extension portion.

[0017] This hair catcher can prevent water that has flowed into the other end from flowing over the standing wall into the main body, thereby allowing the standing wall to guide the water from the other end toward the one end, effectively generating a swirling flow.

[0018] A seventh invention is a hair catcher according to the first or second invention, characterized in that the standing wall portion has a first standing wall portion and a second standing wall portion opposite the first standing wall portion, the first standing wall portion and the second standing wall portion have one side end portion located radially inward from the peripheral end portion of the main body portion, a peripheral wall portion extending circumferentially from the one side end portion along the peripheral end portion of the main body portion, and the other side end portion located on the tip side of the peripheral wall portion, and between the one side end portion of the first standing wall portion and the other side end portion of the second standing wall portion, inlet ports are formed for circulating water toward inside the main body portion between the one side end portion of the first standing wall portion and the other side end portion of the second standing wall portion, and between the other side end portion of the first standing wall portion and the one side end portion of the second standing wall portion.

[0019] According to this hair catcher, even if a large amount of water flows in, a swirling flow can be generated efficiently, and water overflow can be prevented. Effect of the Invention

[0022] Hereinafter, an embodiment will be described with reference to the drawings. In the drawings, like elements are designated by like reference numerals, and detailed description thereof will be omitted as appropriate. FIG. 1 is a perspective view showing a bathroom unit equipped with a hair catcher according to a first embodiment. As shown in FIG. 1, bathroom unit 1 includes a washing area floor 10, a bathtub 100, and wall panels 106a to 106f.

[0023] A washing area floor 10 is installed at the bottom of the space next to the bathtub 100. The surface 10a of the washing area floor 10 is waterproof so that water does not leak outside the bathroom. In this specification, the term "water" includes not only cold water but also heated hot water.

[0024] A drain pipe 102 is provided on the back side (lower side) of the washing area floor 10 near the boundary with the bathtub 100. In the washing area floor 10, for example, near the boundary with the bathtub 100, a drain port 10h that communicates with the drain pipe 102 is formed. The portion where the drain port 10h is provided is recessed downward, and a drain gradient that slopes downward toward the drain port 10h is provided on the surface 10a of the washing area floor 10. In addition, a drain port (not shown) provided at the bottom of the bathtub 100 is also connected to the drain pipe 102.

[0025] A bath apron 104 is provided at the boundary between the bathtub 100 and the washing area floor 10 to cover the side of the bathtub 100 facing the washing area floor 10. Depending on the structure of the bathtub 100, the bath apron 104 may not be provided.

[0026] 1, wall panels 106a-106c are installed on the rim of bathtub 100. Wall panels 106d-106f are installed on the peripheral edge of washing area floor 10. A door is attached to wall panel 106f via a door mounting frame (not shown).

[0027] FIG. 2 is a plan view of the drain outlet in the washing area floor seen from above. FIG. 3 is a plan view showing the drain outlet with the hair catcher removed. FIG. 4 is a cross-sectional view of the drain port and the drain trap in FIG. 3 as viewed from the direction of arrow AA. 2 to 4, a cover member for covering the drain outlet 10h is omitted.

[0028] As shown in Fig. 4, a drain trap 20 is provided below the drain outlet 10h. The drain trap 20 has a seal water storage section 21 and a water seal sleeve 23. The seal water storage section 21 is connected to the drain pipe 102. The seal water storage section 21 stores seal water in its internal space. The water seal sleeve 23 is attached to the seal water storage section 21 in a state where it is inserted into the seal water storage section 21.

[0029] The drain trap 20 has an engagement portion 25 with which the hair catcher 30, described below, engages. The engagement portion 25 is located above the water seal cylinder 23. A plurality of engagement portions 25 (for example, two) are provided spaced apart in the circumferential direction. As shown in FIG. 4, when the hair catcher 30 is attached to the drain trap 20, the lower end side is located inside the water seal cylinder 23.

[0030] Next, the hair catcher 30 will be described. FIG. 5 is a plan view of the hair catcher seen from above. FIG. 6 is a cross-sectional view of the hair catcher in FIG. 5 as viewed from the direction of the arrow BB. FIG. 7 is a side view of the hair catcher. FIG. 8 is a cross-sectional view of the hair catcher as viewed from the direction of arrow CC in FIG. FIG. 9 is a perspective view showing the hair catcher. In the embodiment, the direction from the center of the main body 40 of the hair catcher 30 toward the peripheral end 40c is described as the "radial outer side," and the direction from the peripheral end 40c toward the center of the main body 40 is described as the "radial inner side." Also, the direction in which the peripheral end 40c of the main body 40 extends is described as the "circumferential direction."

[0031] The hair catcher 30 is located inside the drain outlet 10h and attached to the drain trap 20. The hair catcher 30 covers the upper opening of the water sealing cylinder 23. The hair catcher 30 directs water that has flowed into the drain outlet 10h into the water sealing reservoir 21, and collects foreign matter such as hair that has become mixed in the water. The hair catcher 30 has a main body 40 and an upright wall 50 that rises upward from the main body 40.

[0032] The main body 40 is formed, for example, from a resin material in a bowl or hemispherical shape, and is provided with a plurality of drainage holes 41 spaced apart in the circumferential direction. The drainage holes 41 penetrate the main body 40 in the thickness direction (from the inner surface 40a to the outer surface 40b). Water that flows into the main body 40 flows from the drainage holes 41 into the water seal cylinder 23.

[0033] As shown in Figures 7 and 8, the main body 40 has a protrusion 43 that engages with the engagement portion 25 of the drain trap 20. The protrusion 43 is provided to protrude from the outer surface 40b of the main body 40. The protrusion 43 is located above the drain hole 41. The number of protrusions 43 corresponds to the number of engagement portions 25. In this example, the main body 40 has two protrusions 43.

[0034] The hair catcher 30 can be rotated clockwise while inserted into the water seal cylinder 23 to engage the protrusion 43 with the engagement portion 25. In other words, the hair catcher 30 can be attached to and detached from the drain trap 20 by rotating it clockwise or counterclockwise while inserted into the water seal cylinder 23.

[0035] The standing wall portion 50 extends upward from the inner surface 40a of the main body portion 40. The standing wall portion 50 is provided along the peripheral end portion 40c of the main body portion 40. The standing wall portion 50 guides water that has flowed into the drain outlet 10h into the main body portion 40. The standing wall portion 50 is also a portion that is held with fingers when attaching or detaching the hair catcher 30 from the drain trap 20.

[0036] The standing wall portion 50 is softer than the main body portion 40. The Shore hardness (Hs) of the standing wall portion 50 is, for example, 30 or more and 70 or less. The standing wall portion 50 is formed in a plate shape using a flexible member such as rubber or elastomer. In other words, the standing wall portion 50 has elasticity. This allows the standing wall portion 50 to be easily elastically deformed by hand. Therefore, even if the hair catcher 30 is still attached to the drain trap 20, the user can easily clean the drain outlet 10h by elastically deforming the standing wall portion 50. In addition, the user can easily clean the hair catcher 30 itself.

[0037] On the other hand, the standing wall portion 50 has a hardness such that it will not collapse under the water pressure flowing into the drain outlet 10h. As a result, as shown by the arrow in Figure 2, the standing wall portion 50 is able to generate a swirling flow in the water flowing into the main body portion 40. Therefore, the hair catcher 30 can collect hair and the like within the main body portion 40.

[0038] The main body 40 and the standing wall 50 are integrally molded, for example, by two-color molding, which can improve the durability of the hair catcher 30. The main body 40 and the standing wall 50 may also be integrally molded, for example, by using an adhesive.

[0039] The standing wall portion 50 has a first standing wall portion 60 and a second standing wall portion 70 facing the first standing wall portion 60. The first standing wall portion 60 is provided in a circumferential half position of the main body portion 40, and the second standing wall portion 60 is provided in a circumferential half position of the main body portion 40. The first standing wall portion 60 and the second standing wall portion 70 have the same shape and configuration, so hereinafter, the first standing wall portion 60 will be described, and a description of the second standing wall portion 70 will be omitted.

[0040] The first standing wall portion 60 has one side end portion 61 located radially inward from the peripheral end portion 40c of the main body portion 40, a peripheral wall portion 63 extending circumferentially from the one side end portion 61 along the peripheral end portion 40c of the main body portion 40, and the other side end portion 65 located on the tip side of the peripheral wall portion 63.

[0041] The one side end 61 is one of the circumferential ends of the first standing wall portion 60. As shown in Figs. 5 and 6, the one side end 61 is located between the circumferential end 40c of the main body portion 40 and the drain hole 41. The one side end 61 has an extension portion 61a extending upward from the inner surface 40a of the main body portion 40, and a bent portion 61b bent radially outward from the upper end of the extension portion 61a. The tip of the bent portion 61b is located radially inward from the circumferential end 40c of the main body portion 40. The bent portion 61b prevents water from flowing over the bent portion 61b into the main body portion 40.

[0042] The peripheral wall portion 63 connects between the one side end portion 61 and the other side end portion 65. The peripheral wall portion 63 has an extension portion 63a extending upward from the inner surface 40a of the main body portion 40, and a bent portion 63b bent from the upper end of the extension portion 63a toward the radially outward direction. As shown in FIG. 5 and FIG. 8, the tip of the bent portion 63b of the peripheral wall portion 63 protrudes toward the radially outward direction beyond the peripheral end portion 40c of the main body portion 40. The bent portion 63b prevents water from flowing over the bent portion 63b into the main body portion 40. Also, as shown in FIG. 5, the peripheral wall portion 63 extends so that the curvature is different between the one side end portion 61 and the other side end portion 65. Specifically, the curvature from the one side end portion 61 to the point X is larger than the curvature from the point X to the other side end portion 65. The point X is a transition point where the curvature of the peripheral wall portion 63 changes.

[0043] The other end 65 is the other end of the first standing wall portion 60 in the circumferential direction. As shown in Figs. 5 and 6, the other end 65 is located on the circumferential end 40c of the main body portion 40. The other end 65 has an extension portion 65a extending upward from the inner surface 40a of the main body portion 40, and a bent portion 65b bent radially outward from the upper end of the extension portion 65a. The tip of the bent portion 65b protrudes radially outward beyond the circumferential end 40c of the main body portion 40. The bent portion 65b prevents water from flowing over the bent portion 65b into the main body portion 40.

[0044] The first standing wall portion 60, by the bent portions 61b, 63b, and 65b, prevents the water that has flowed into the drain outlet 10h from climbing over the first standing wall portion 60 and flowing into the main body portion 40. This allows the first standing wall portion 60 to generate a stable swirling flow in the water that has flowed into the drain outlet 10h.

[0045] The upper end of the first standing wall portion 60 is curved upwardly in a convex shape. As shown in Fig. 7 and Fig. 8, the first standing wall portion 60 has its highest position above the protrusion 43 of the main body portion 40. In other words, the height dimension of the first standing wall portion 60 from the inner surface 40a of the main body portion 40 is greatest above the protrusion 43 of the main body portion 40.

[0046] This allows the user to rotate the hair catcher 30 by pinching the upper part of the protrusion 43, which is the tallest part of the first standing wall portion 60, with their fingers when attaching or detaching the hair catcher 30 from the drain trap 20. In addition, the first standing wall portion 60 is made easy to pinch with the fingers due to the bent portion 63b. Therefore, since the user pinches the upper part of the protrusion 43 with their fingers, it is easy to transmit the force of the hand to the protrusion, and the hair catcher 30 can be rotated stably.

[0047] The second standing wall portion 70 has the same shape and configuration as the first standing wall portion 60. That is, the second standing wall portion 70 has one side end portion 71, a peripheral wall portion 73, and an other side end portion 75. The one side end portion 71 has an extending portion 71a and a bent portion 71b. The peripheral wall portion 73 has an extending portion 73a and a bent portion 73b. The other side end portion 75 has an extending portion 75a and a bent portion 75b.

[0048] 5, one side end 71 of the second standing wall portion 70 is located radially inward from the other side end 65 of the first standing wall portion 60. Moreover, the other side end 75 of the second standing wall portion 70 is located radially outward from the one side end 61 of the first standing wall portion 60. As a result, inlets 80, 81 that allow water to flow toward the inside of the main body portion 40 are formed between the one side end 61 of the first standing wall portion 60 and the other side end 75 of the second standing wall portion 70, and between the other side end 65 of the first standing wall portion 60 and the one side end 71 of the second standing wall portion 70.

[0049] As shown by the arrows in Fig. 2, part of the water that flows into the drain outlet 10h flows along the outer peripheral surface of the first standing wall portion 60, and then flows from the inlet 80 along the inner peripheral surface of the second standing wall portion 70. Another part of the water that flows into the drain outlet 10h flows along the outer peripheral surface of the second standing wall portion 70, and then flows from the inlet 81 along the inner peripheral surface of the first standing wall portion 60. This allows the hair catcher 30 to generate a swirling flow within the main body portion 40. The hair catcher 30 can gather the hair that has flowed into the main body portion 40 in the center of the main body portion 40 by using this swirling flow.

[0050] In the hair catcher 30 according to this embodiment, the standing wall portion 50 is softer than the main body portion 40. In this case, the standing wall portion 50 is formed of, for example, a flexible material. The Shore hardness of the standing wall portion 50 is, for example, 30 or more and 70 or less.

[0051] As a result, even when the hair catcher 30 is attached to the drain trap 20, the standing wall portion 50 can be elastically deformed to allow a user to insert a hand or a cleaning tool between the wall portion of the drain outlet 10h and the standing wall portion 50. As a result, the user can efficiently clean the drain outlet 10h. In addition, the user can efficiently clean the inner surface 40a of the main body portion 40 by elastically deforming the standing wall portion 50. In addition, the main body portion 40 and the standing wall portion 50 of the hair catcher 30 are integrally molded by two-color molding. This allows the durability of the hair catcher 30 to be improved.

[0052] The part of the standing wall 50 that is located above the protrusion 43 of the main body 40 is the highest. This allows the user to intuitively pinch the part of the standing wall 50 that is located above the protrusion 43 with his or her fingers. As a result, when attaching or detaching the hair catcher 30 to or from the drain trap 20, the hair catcher 30 can be rotated efficiently.

[0053] In addition, the upper end side of the standing wall portion 50 is bent radially outward. This makes it possible to prevent water that has flowed into the drain outlet 10h from climbing over the standing wall portion 50 and flowing into the main body portion 40. In addition, the user can easily lift the hair catcher 30 by pinching the standing wall portion 50.

[0054] The standing wall portion 50 has a first standing wall portion 60 and a second standing wall portion 70. Between the first standing wall portion 60 and the second standing wall portion 70, inlets 80, 81 are provided to allow the water that has flowed into the drain outlet 10h to flow into the main body portion 40. The hair catcher 30 can generate a swirling flow in the main body portion 40 by the first standing wall portion 60, the second standing wall portion 70, and the inlets 80, 81. As a result, the hair catcher 30 can collect hair and the like in the main body portion 40 all at once.

[0055] FIG. 10 is a perspective view showing a hair catcher according to the second embodiment. The hair catcher 30 according to the first embodiment described above has been described by taking as an example a case in which the part of the standing wall portion 50 located above the protrusion 43 of the main body portion 40 is made the highest so that the user can intuitively pinch it with their fingers. However, as in a second embodiment shown in Fig. 10, the first standing wall portion 60 and the second standing wall portion 70 may have a gripping portion 91 that the user grips when attaching or detaching the hair catcher 90. The gripping portion 91 is provided, for example, above the protrusion 43 of the main body portion 40.

[0056] The vertical wall portion 50 may have different thicknesses. For example, the first vertical wall portion 60 may have a gradually increasing thickness from one end portion 61 to the other end portion 65, or may have a gradually increasing thickness from the other end portion 65 to the one end portion 61. The same applies to the second vertical wall portion 70. That is, the vertical wall portion 50 may have, in the circumferential direction, a thick portion having a large radial thickness and a thin portion having a smaller thickness than the thick portion.

[0057] The thick wall portion of the vertical wall portion 50 can increase the rigidity. Therefore, when attaching or detaching the hair catcher to or from the drain trap 20, the user can grip the thick wall portion to rotate the hair catcher efficiently. This makes the hair catcher easy to use.

[0058] In the above embodiment, the upper end of the standing wall portion 50 is curved upwardly in a convex shape. However, the present invention is not limited to this. For example, the upper ends of the standing wall portion 50 may be the same height.

[0059] The embodiment may include the following features.
