The drain trap 1 has a collecting member 10 and an attachment member 20 shown in FIGS. 1 to 5 in order to collect garbage such as hair from the waste water.
The collecting member 10 protrudes from the outer edge portion 13 of the collecting member main body portion 12 to the outer direction D1 of the outer edge portion 13 for collecting the hair in the wastewater while allowing the wastewater to pass therethrough. And a handle 16. In this embodiment, as shown in FIG. 3, the whole ceiling part 12a of the collection member main body part 12, the upper side of the side parts 12b and 12c, and the upper side of the back part 12d are holes 14a for allowing drainage to pass through. Is a water passage 14 formed in a large number of meshes. On the other hand, the bottom surface portion of the collecting member main body 12 is a flow path extension 15 having no holes 14a. The handle 16 protrudes linearly from the base 16b to the tip 16a. The collection member 10 is formed in a substantially handle-like shape in which the collection member main body 12 is substantially in the shape of a basket.

The outer direction D1 of the outer edge portion 13 is a direction along a virtual plane PL1 along the outer edge portion 13 as shown in FIG. 4 and FIG. The direction toward the part not surrounded by the part 13 shall be said. Therefore, the handle 16 protrudes from the outer edge portion 13 in this direction. Here, the direction along the plane PL1 includes not only the direction coinciding with the plane PL1, but also the direction shifted within the range of θ ₁ = 30 ° from the direction coinciding with the plane PL1 as shown in FIG. Further, in the case of the collecting member 110 in which all the outer edge portions 113 are not on the same plane as shown in FIG. 5B, the outer direction D1 of the outer edge portion 113 is along the outer edge portion 113 where the handle 116 protrudes. The direction along the virtual plane PL2 shall be said.

  The mounting member 20 has a flow path forming portion 22 that guides the wastewater flowing in from above to a predetermined flow direction D3 that is shifted from the vertical direction D2, and at the position L1 that allows the guided wastewater to pass, Removably attach. As shown in FIG. 2C and FIG. 4, the flow direction D3 of the present embodiment is only one direction that is obliquely downward from the horizontal direction. The attachment member 20 is formed in a shape recessed downward, and the vicinity of the upper edge portion is a substantially cylindrical fitted portion 26 that fits inside the tightening flange cylindrical portion 41. The fitting portion 26 is formed with through holes 26a into which the projections 41b on the upper side of the tightening flange cylindrical portion 41 can be inserted at four locations at intervals of 90 °, and grooves 26b are respectively formed downward from the through holes 26a.

By aligning each groove 26b with the protrusion 41b on the upper side of the tightening flange and inserting the mounting member 20 into the opening of the tightening flange 40 and rotating it, each protrusion 41b on the upper side of the tightening flange cylindrical part 41 is inserted into each through hole 26a. The attachment member 20 is fixed at a predetermined position of the drain trap 1 in the inserted state.

The flow path forming part 22 has an inclined part 23 and a side part 24.
An opening 25 for detachably attaching the collection member main body 12 is formed in the side surface 24 that is the flow direction D3 into which the drainage is guided. The main opening 25 is formed in a substantially rectangular shape according to the outer shape of the collecting member main body 12. When the collection member main body 12 is attached to the opening 25, the handle 16 protrudes obliquely upward from the outer edge portion 13 of the collection member main body. The protrusion direction D4 of the handle 16 at this time is shown in FIG. If the handle 16 protrudes in the protruding direction D4, the size of the drainage basin 83 is not easily limited in the horizontal direction, and thus the handle 16 can be lengthened. For this reason, the protruding direction D4 of the handle is preferably the vertical direction D2 or a direction close to the vertical direction D2, and the deviation θ ₂ from the vertical direction D2 is preferably 45 ° or less.

The inclination part 23 inclines along the flow direction D3 so that it may connect with the flow-path extension part 15 of the collection member main-body part 12 attached to the said side part. Accordingly, the waste water that has flowed from above onto the inclined portion 23 is guided toward the collection member main body 12 on the inclined portion 23 and flows from above the flow path extension portion 15 to the water passing portion 14. A plurality of holes 23 a through which drainage passes are formed on the upstream side of the main inclined portion 23. Although a part of the drainage passes through the hole 23a downward, the drainage flows on the inclined portion 23 in the flow direction D3 obliquely below, so that hair or the like in the drainage is not easily caught near the hole 23a. Therefore, the hole 23a is not easily blocked, and the drainage capacity of the drain trap 1 is maintained.
Further, a stepped portion 23 b that is lowered by one step is formed at the downstream edge of the inclined portion 23. Thereby, when the collection member main body 12 is attached to the opening 25, the upper surface of the inclined portion 23 and the upper surface of the flow path extension portion 15 are substantially flush with each other, and the drainage flows from above the inclined portion 23 to the flow path extension portion 15. Smoothly flows up.

Moreover, as shown in FIG. 4, the virtual plane PL1 along the outer edge part 13 of the collection member main body part 12 attached to the opening part 25 is inclined obliquely from the vertical direction D2. That is, the attachment member 20 is detachably attached to the collection member main body 12 with the outer edge portion 13 of the collection member main body being inclined obliquely from the vertical direction. Here, the plane PL1 along the outer edge portion 13 is preferably directed in the vertical direction D2 or in a direction close to the vertical direction D2, and is directed in a direction in which the deviation θ ₃ from the vertical direction D2 is 45 ° or less. Is preferred.
On the other hand, the inclination of the inclined portion 23, that is, the inclination of the flow direction D1, is preferably in a direction orthogonal to the plane PL1 along the outer edge portion or a direction close to the orthogonal direction, and the deviation θ ₄ from the horizontal direction is 45 ° or less. Orientation is preferred.

  Each member 10, 20, 30, 40, 50 constituting the drain trap 1 can be made of various materials such as a resin molding material such as a thermoplastic resin, a metal such as stainless steel, etc. A molded article or the like can be used.

  In the drain trap 1 having the above-described configuration, for example, the packing 44 is attached to the front end portion of the floor material flange portion 83a, and the tightening flange 40 is screwed into the flange portion 33 of the trap body, whereby the floor material flange portion 83a and the trap body 30 are connected. Are fixed to each other, the sealing tube 50 is attached to the fastening flange 40, the attachment member 20 is attached to the fastening flange 40, and the collection member main body 12 is attached to the opening 25 of the attachment member. Of course, the drainage trap 1 may be formed by attaching the attachment member 20 to which the collection member main body 12 is attached to the fastening flange 40. As shown in FIG. 1, the handle 16 protrudes obliquely upward in the drainage basin 83, so that a cover 84 can be provided on the drainage basin 83.

(2) Action and effect of drain trap:
Next, the action and effect of this drain trap will be described.
The waste water that has flowed into the drainage basin 83 flows downward toward the mounting member 20, changes the flow direction to the flow direction D 3 that is shifted from the vertical direction D 2 on the inclined portion 23, and is directed toward the collection member main body 12. As a result, it passes through the water passage 14. Since many holes 14 a are formed in the water passage portion 14, the hair or the like in the drainage is collected by the water passage portion 14 and stays in the collecting member main body portion 12.

Here, the back surface portion 12d of the collecting member main body portion is inclined in the direction inclined obliquely from the vertical direction D2, and the drainage flows in one direction in the flow direction D3. The water part 14 is not easily blocked. In the hair catcher 920 shown in FIG. 10C, the drainage flows from all directions of 360 ° and passes through the substantially conical portion 922 downward. It is considered that the drainage flow path may adhere and become blocked.
Further, when the drainage does not flow and the water passing portion 14 is dried, the waste W1 such as hair attached to the water passing portion 14 falls due to gravity in the collecting member main body 12 as shown in FIG. To do.
From the above, clogging of the water passing portion 14 is suppressed.

  When removing hair or the like remaining in the collection member main body 12, the cover 84 is removed from the drainage basin 83, the handle 16 is held by hand, and the collection member main body 12 is removed from the mounting member 20 to collect the hair. The operation of discarding the hair or the like in the member main body 12 is performed. The handle 16 that protrudes obliquely upward from the outer edge portion 13 of the collecting member main body is long because it is difficult to be limited in the horizontal size of the drainage basin 83. Therefore, it is easy to take out the collecting member main body 12 and to easily turn the collecting member main body 12 over. In addition, since the length of the horizontal direction D93 of the handle 926 is short, the hair catcher 920 shown in FIG.10 (c) cannot take out the hair catcher 920 easily, and it is difficult to perform the operation which turns the hair catcher 920 over.

Further, in the conventional hair catcher 910 shown in FIG. 10 (b), the hair or the like does not fall even if the handle is turned sideways, but the collecting member 10 has the handle 16 turned sideways by hand as shown in FIG. When the opening 12e of the collecting member main body 12 is directed downward, the hair or the like in the collecting member main body 12 falls. Of course, since the handle 16 protrudes from the outer edge portion 13 of the collecting member main body portion in the outer direction D1 of the outer edge portion, the hair or the like accumulated in the collecting member main body portion 12 does not fall into the hand. Therefore, hair etc. can be thrown away without discomfort.
As described above, according to the present invention, it is possible to dispose of hair collected in the collecting member of the drain trap without discomfort, to facilitate the care of the collecting member, and to easily dispose of hair and the like. Become.

Moreover, since the inclined part 23 is provided so that it may connect with the collection member main-body part 12 attached to the side part 24 of an attachment member, the waste_water | drain which flowed into the attachment member 20 is toward the collection member main-body part 12 efficiently. The hair in the drainage is collected more efficiently.
Furthermore, since the collection member main body 12 is attached to the opening 25 of the attachment member with the outer edge 13 inclined obliquely from the vertical direction, the collection member main body 12 is attached to and detached from the attachment member 20. easy. Further, when the drainage stops flowing, the collected hair and the like fall due to gravity in the collecting member main body 12. Therefore, clogging of the collecting member main body 12 can be suppressed.

It is a hair catcher provided in the drain trap,
A collecting member 10 having a collecting member main body for collecting hair in the waste water while allowing the drainage to pass through, and a handle protruding outward from the outer edge of the collecting member main body,
The wastewater flowing in from above is guided in a predetermined direction deviated from the vertical direction, and the mounting member 20 is detachably attached to the collection member main body at a position where the guided wastewater is allowed to pass through,
