  Next, the operation of the drain trap 10 will be described.

  Drainage from the washing area pan 2 flows into the trap chamber 20 through the drainage basin 4 and the washing area drainage receiving port 11, and flows out from the confluence outlet 14 to the drainage pipe 6 through the lower side of the sealing tube 32. When the outflow of the washing ground drainage stops, the sealed water remains in the trap chamber 20, and the lower end of the sealing cylinder 32 is submerged in the sealing water, so that the odor of the drain pipe 6 enters the bathroom from the washing ground drain receiving port 11. Backflow is prevented.

  The drainage from the bathtub 3 and the bathtub pan flows out from the drain outlets 3a and 1a, the bathroom drainage inlet 12, and the bathtub pan drainage inlet 13 to the drain pipe 6 through the bathtub drainage channel 23 and the junction outlet 14. . At this time, a part of the water flowing through the bathtub drainage channel 23 flows into the water guide member body 40 in the middle of the bathtub drainage channel 23, passes through the branch pipe part 42, and enters the trap chamber 20 from the outlet 54. Since it flows out in the circumferential direction, a swirl flow is formed in the receiving chamber 20. Moreover, the water level in the trap chamber 20 rises due to the inflow of water, the hair catcher 37 is immersed in the swirling flow, and dust such as hair in the hair catcher 37 is collected at the center of the hair catcher 37. As a result, the garbage can be picked and thrown away. Further, the inner and outer surfaces of the hair catcher 37 are immersed in the swirling flow to be purified, and slime and the like are removed.

  As shown in FIG. 4, when the hair catcher 37 and the coronal portion 53 of the nozzle body 50 before the start of the bathtub drainage are extremely close to each other, the nozzle body 50 does not rise at all or hardly after the start of the bathtub drainage. Outflow water from the outlet 54 flows out from the outlet 54 immediately below the hair catcher 37, and a strong swirling flow is formed in the vicinity of the hair catcher 37.

  On the other hand, as shown in FIG. 5, when the hair catcher 37 is separated upward from the nozzle body 50 before the start of bath drainage, the coronal portion 53 is caused by the water pressure flowing into the water guide member body 40 after the bath drainage starts. Until the nozzle body 50 comes into contact with the hair catcher 37. Therefore, even in this case, the outflow water from the outlet 54 flows out from the outlet 54 immediately below the hair catcher 37, and the hair catcher 37 is immersed in a powerful swirling flow. The nozzle body 50 is smoothly moved up and down while being guided by the upper end portion of the branch pipe portion 42 and the guide protrusion 32b.

  In this way, regardless of the height from the nozzle body 50 to the hair catcher 37, the entire hair catcher 37 is sufficiently washed, and dust such as hair is peeled off from the entire upper surface of the hair catcher 37. It becomes like this.

  In particular, in this embodiment, the ring body 51 is provided in the nozzle body 50, and most of the water flowing out from the outlet 54 swirls on the periphery 51, so that the swirl flow becomes strong.

  When the outflow of the bathtub drainage stops, the sealing water remains in the bathtub drainage flow path 23 to the level of the lower edge of the junction outlet 14, so that the odor of the drainage pipe 6 becomes the bathtub drainage inlet 12 and the bathtub pan drainage inlet 13. It is prevented from flowing back into the bathtub or bathroom.

  Since the nozzle body 50 used in this embodiment has a diameter larger than the inner diameter of the water sealing cylinder 32, the nozzle body 50 does not fall into the water sealing cylinder even if it is detached from the water guide member main body 40.

  In the above embodiment, the nozzle body 50 is fitted to the upper end of the branch pipe portion 42 so as to be movable up and down, and the height of the outlet 54 can be changed. For example, the base end annular portion 41 of the water guide member moves up and down. It may be set as other modes, such as being constituted by two bodies fitted so as to be possible.
