JP 2001-65025 A

  The present invention has been invented in view of the above-described conventional problems, and can improve the efficiency of capturing hair during drainage, reduce the number of cleanings, and provide a hair catcher that has an excellent clogging prevention function. It is an object to provide a hair catcher that can easily remove hair during cleaning.

  In order to solve the above-mentioned problem, the present invention opens a drainage inflow portion 2 for allowing drainage to flow from a certain direction A into one side surface 1b of the drainage cover portion 1 that covers the drainage hole 7 of the floor pan 9. The hair catcher body 3 is detachably attached to the lower side, and the hair catcher body 3 is provided with a number of drain holes 4 and a number of projections 5 protruding upward from the hair catcher body surface 3a. 5 is inclined at an acute angle θ1 toward the drainage inflow portion 2 side and with respect to the hair catcher body surface 3a.

  With such a configuration, the drainage flow from the drainage inflow portion 2 of the drainage cover portion 1 to the hair catcher main body 3 is in a fixed direction A, and the drainage comes into contact with each one surface 5a of the many protrusions 5. . At this time, the hair 6 contained in the waste water is attracted to and captured by the one surface 5a inclined at the acute angle θ1 of the protrusion 5 and is not detached from the protrusion 5 due to the flow of the waste water. Therefore, the hair capturing efficiency by the protrusions 5 is improved, and clogging of the drain holes 4 can be prevented.

  Further, the back surface 5b opposite to the one surface 5a facing the drainage inflow portion 2 of the protrusion 5 is inclined in the same direction as the inclination direction of the one surface 5a and at an obtuse angle θ2 with respect to the hair catcher body surface 3a. In this case, when removing the hair catcher body 3 for cleaning, for example, shower water is applied from the side of the back surface 5b opposite to the one surface 5a of the many protrusions 5 to thereby provide one surface of the protrusion 5 The hair captured on the 5a side is easily detached by the water flow from the back surface 5b side, and can be easily washed away.

  Moreover, it is preferable to arrange the drainage hole 4 between the adjacent projections 5, and in this case, the projections 5 are located on both sides of the drainage hole 4, so that the drainage hole 4 is disposed. It is possible to efficiently capture the hair that is about to flow down from the protrusion 5 with the protrusions 5.

  The invention described in claim 1 rectifies the drainage flow from the drainage inflow part of the drainage cover part to the hair catcher body in a certain direction, and directs one side of many protrusions from the surface of the haircatcher body toward the drainage inflow part side. By inclining at an acute angle, it becomes easier to capture hair during drainage, and as a result, the number of cleanings of the hair catcher body can be reduced and the effect of preventing clogging can be enhanced.

  In the invention according to claim 2, when the back surface of the projection is inclined at an obtuse angle, when removing the hair catcher main body and cleaning it, shower water is applied from the back side opposite to one side of many projections. The hair can be easily removed from the protrusions, and cleaning is easy.

  In the invention according to the third aspect, the hair catching efficiency can be further improved by disposing a drain hole between the adjacent protrusions.

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