Thus, clogging can be prevented.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  First, the drainage structure in which the hair catcher 1 of this example is installed will be described. As shown in FIG. 3, the drain port 2 where the hair catcher 1 of this example is installed is formed in the bathroom washroom. The bathroom floor pan 3 is provided with a washing place part 4 constituting a washing place and a bathtub setting part 5 where a bathtub is installed. A recess 6 is formed at the end of the washing section 4 on the bathtub installation section 5 side, and an attachment port 7 is formed at the bottom of the recess 6. A drainage trap 8 is attached to the attachment port 7, and the drainage trap 8 includes a container-like trap body 9 disposed below the attachment port 7, a mounting cylinder 10 attached to the trap body 9, a trap And a sealed cylinder 11 inserted inside the main body 9.

  The lower part of the mounting cylinder 10 is screwed into the opening 9 a formed on the upper surface of the trap body 9, and the upper flange 13 protruding from the outer periphery of the upper end of the mounting cylinder 10 and the trap body 9. The trap body 9 is attached to the attachment port 7 in a watertight manner by sandwiching the periphery of the attachment port 7 via the packing 14 with the periphery of the opening 9a. An outlet portion 15 is provided at the upper part of the outer peripheral wall portion of the trap body 9, and a drain pipe 16 for discharging the waste water in the trap body 9 to sewage is connected to the outlet portion 15.

  A lower flange 17 protrudes from the inner periphery of the lower end of the mounting cylinder 10, and a flange 18 is provided on the lower flange 17 so as to surround the upper end of the sealed cylinder 11. The lower part of the sealing cylinder 11 is inserted to a position below the outlet 15 of the trap body 9 and is immersed in the water stored in the trap body 9, thereby forming a sealed part in the trap body 9. ing. The drain port 2 is constituted by an upper end opening of the mounting cylinder 10, and the hair catcher 1 is detachably attached to the drain port 2.

  A drainage cover 19 that covers the upper side of the drainage port 2 is disposed in the recess 6 described above. The drainage cover 19 is installed above the hair catcher 1 by placing a leg portion 21 projecting downward from the outer peripheral portion on the bottom of the recess 6 that is one step higher than the peripheral edge of the attachment port 7. Yes. Between the drainage cover 19 and the bottom of the recess 6, a running water gap 22 is formed which includes an opening 12 formed between a plurality of legs 21 protruding downward from the outer peripheral edge of the drainage cover 19. The gap 22 is formed on all sides of the drainage cover 19 so that drainage flows from all sides of the drainage cover 19.

  In the drainage structure, the water on the washing area 4 of the floor pan 3 is drained from the gap 20 between the inner circumferential surface of the recess 6 and the outer circumferential surface of the drainage cover 19 through the drainage cover 19. , Then flows into the drain 2 and the hair catcher 1 collects hair and dust, and then is discharged to the outside through the sealing cylinder 11, the trap body 9, and the drain pipe 16 in this order. .

  Hereinafter, the hair catcher 1 installed in the said drain port 2 is explained in full detail based on FIG.1 and FIG.2. In the following description, the drainage portion 27 side of the later-described drainage portion 27 and the upright portion 35 is defined as the front side, and the upright portion 35 side is defined as the rear side.

  The hair catcher 1 of this example shown in FIG. 1 is composed mainly of a hair catcher body 23 having a circular shape in a plan view and a shallow dish shape. An annular outer peripheral frame 24 protruding outward is provided at the upper end edge of the hair catcher main body 23, and the outer peripheral frame 24 constitutes the outer peripheral edge of the hair catcher main body 23. As shown in FIG. 2, extending portions 25 extending downward are formed on the left and right sides of the outer peripheral frame 24 sandwiching the central portion of the hair catcher body 23, and each extending portion 25 has a hair catcher body A locking groove 26 that extends in the circumferential direction of 23 and opens to the outside of the hair catcher body 23 is formed.

  The one side area | region in the front-back direction of the center part enclosed by the outer periphery frame 24 of the hair catcher main body 23 is the drainage part 27 hollowed rather than the outer periphery of the hair catcher main body 23, and the center angle of the drainage part 27 of the example of illustration is 180 degree | times. The fan has a fan shape in plan view. A large number of circular drain holes 28 penetrating up and down are formed in the drain part 27 over substantially the entire region, and when draining, drainage is performed through the numerous drain holes 28 of the drain part 27, Such garbage is collected. The drainage portion 27 is provided with a water gradient that slopes downward from the left and right sides toward the center, and dust such as hair contained in the drainage is mainly in the central portion in the left-right direction located at the lowest position of the drainage portion 27. accumulate.

  In order to prevent the drainage from overflowing when the drain hole 28 is clogged with dust in the area opposite to the drain part 27 of the hair catcher body 23 and surrounded by the outer peripheral frame 24 of the hair catcher body 23. An overflow water discharge part 29 is provided. The overflow water discharge portion 29 is formed by forming a large number of overflow holes 31 at the upper end portion of the rising portion 35 that is integrally raised from the hair catcher body 23.

  The upright part 35 is formed in a substantially cylindrical shape with a center angle of 90 degrees or more centered on the center of the circular hair catcher body 23 in a plan view, and is opposite to the drainage part 27 raised from the hair catcher body 23. The outer surface on the side is an arcuate surface 30 that is concentric with the hair catcher body 23 in plan view, and is along the outermost periphery of the hair catcher body 23. For this reason, the standing portion 35 is less likely to catch relatively long dust such as hair, and the arc-shaped surface 30 can smoothly guide the drainage to the drainage portion 27.

  The upright portion 35 protrudes above the drainage port 2 in a state where the hair catcher 1 is installed at the drainage port 2, and an overflow hole 31 penetrating vertically is formed in a horizontal upper surface plate portion 34 that closes the upper end of the upright portion 35. Many are formed over substantially the whole area. Note that the term “many” mentioned here does not include those in which the ribs 40 are installed between the hole edges of the cylindrical overflow water discharge portion 29 ′ and divided into two sections or four sections as in the prior art. The number of the overflow holes 31 is formed to be 5 or more. Specifically, the number of the overflow holes 31 is formed so that dust such as hair can be sufficiently collected. Each overflow hole 31 is a circular hole having substantially the same diameter as the drain hole 28 formed in the drain part 27, and each overflow hole 31 communicates downward through the lower end opening of the cylindrical upright part 35. Therefore, when the drainage water level is located above the upright portion 35 because the many drainage holes 28 of the drainage section 27 are clogged with dust, the overflow water can be drained through the numerous overflow holes 31. It has become. The overflow water may contain dust such as hair. In the hair catcher 1 of this example, the overflow hole having a small opening area is formed in the upper surface plate portion 34 of the upright portion 35 as described above. Since a large number of 31 is formed, dust such as hair contained in the overflow water can be collected in the same manner as the drainage portion 27 by the upper surface plate portion 34 in which a large number of overflow holes 31 are formed.

  Further, a knob portion 32 for picking with a finger is projected from the upper end portion of the raised portion 35, and a handle is constituted by the raised portion 35 having the overflow hole 31. That is, the rising portion 35 serves as both a flow path for discharging overflow water and a rising portion of the handle. The knob portion 32 is formed in a plate shape and protrudes from the upper surface plate portion 34 of the raised portion 35 in a direction away from the center of the circular hair catcher body 23. Since the knob 32 is located above the peripheral edge of the drain 2 (that is, the upper flange 13 of the mounting cylinder 10) with the hair catcher 1 installed at the drain 2, the knob 32 is held with a finger. The hair catcher 1 installed at the drain port 2 can be easily and cleanly removed. Further, when removing dust such as collected hair, dust can be easily shaken off by picking the knob 32 with a finger and inverting and shaking the hair catcher 1 up and down.

  In order to attach the hair catcher 1 to the drain port 2 in the drainage structure described above, the hair catcher 1 is rotated in the circumferential direction after the hair catcher body 23 is inserted into the drain port 2 (that is, the mounting cylinder 10). Thus, the locking protrusion 33 protruding from the inner surface of the drain port 2 is inserted and locked from one end opening of each locking groove 26. Further, in order to take out the hair catcher 1 from the drain port 2 during maintenance, etc., the hair catcher 1 in the attached state is rotated in the direction opposite to that at the time of attachment, and the locking projections 33 are pulled out from the respective locking grooves 26. The lock is then released, and then the hair catcher 1 is pulled upward.

  As described above, the hair catcher 1 described above can collect dust such as hair by the upper surface plate portion 34 of the raised portion 35 in which a large number of overflow holes 31 are formed when overflow water is drained. It is possible to prevent clogging due to dust flowing out into a flow path constituted by piping or the like on the downstream side of 1.

  The hair catcher 1 has a covered cylindrical upright portion 35 raised from one side of the hair catcher main body 23, and a large number of overflow holes 31 are formed in the upper surface plate portion 34 of the upright portion 35. As in the example of the hair catcher 1, a covered cylindrical upright portion 35 is raised from the center of the hair catcher body 23, and a number of overflow holes 31 are formed in the upper surface plate portion 34 that closes the upper end of the upright portion 35. May be. Hereinafter, another example of the hair catcher 1 will be described in detail. In the following explanation, the same number is given about the same composition as hair catcher 1 of the above-mentioned example, and duplicate explanation is omitted as much as possible.

  The hair catcher 1 of this example shown in FIG. 4 is composed mainly of a hair catcher body 23 having a circular shape in plan view. The outer peripheral frame 39 of the hair catcher main body 23 is formed in a cylindrical shape, and is a locking groove similar to the locking groove 26 of the example hair catcher 1 that is locked to the outer peripheral surface of the outer peripheral frame 39 by the locking projection 33 (see FIG. (Not shown). Handles 40 projecting upward are provided at two locations on the outer peripheral frame 39 that face each other across the central portion of the hair catcher body 23.

  At the center of the hair catcher body 23, a covered cylindrical upright portion 35 that is integrally raised from the hair catcher body 23 is formed. In addition, the knob | pick part 32 is not provided in the standing part 35. As shown in FIG. The hair catcher 1 of this example has an annular region surrounded by the peripheral frame of the hair catcher main body 23 and the upright portion 35 as a drainage portion 27, and has a circular drainage hole over the entire area of the annular drainage portion 27 in plan view. Many 28 are formed. A large number (5 or more) of circular overflow holes 31 having the same diameter as the drainage holes 28 are formed in the circular upper surface plate portion 34 of the overflow water discharge portion 29 raised from the central portion of the hair catcher body 1. doing.

  As described above, even in the hair catcher 1 of the example described above, dust such as hair can be collected by the upper surface plate portion 34 of the raised portion 35 in which a large number of overflow holes 31 are formed when overflow water is drained.
