Backflow from the receiving port 11 into the bathroom is prevented.

  Next, the operation | movement at the time of discharge of the bathtub drainage of this drain trap 10 is demonstrated in detail.

[Swivel mode]
As shown in FIGS. 1 to 3 and 5, the inlet 22 is positioned on the upper side of the plate 21P. Since the drainage from the bathtub 3 passes through the bathtub drainage inlet 12 and the duct portion 14 and flows out tangentially from the introduction port 22 into the receiving chamber 20, a swirling flow is formed in the receiving chamber 20. Moreover, the water level in the receiving chamber 20 rises due to the inflow of the bathtub drainage, 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.

  In this embodiment, the inlet 22 is provided in the upper part of the receiving chamber 20, and a strong swirling flow is formed in the upper part of the receiving chamber 20, that is, in the vicinity of the hair catcher 37. Thereby, the dust in the hair catcher 37 is efficiently collected near the center, and the hair catcher 37 is washed by a strong swirl flow. In addition, even when the water level of bathtub drainage is low, the swirl flow in the upper part in the receiving chamber 20 becomes sufficiently strong.

  Moreover, in this embodiment, since the duct portion 14 extends linearly in a substantially tangential direction of the receiving chamber 20, the bathtub drainage flows into the receiving chamber 20 from the inlet 22 without diverting the water flow. As a result, the swirl flow in the receiving chamber 20 is also strong.

[High-speed drain mode]
When the mode for discharging the drainage from the bathtub 3 at a high speed is taken out, the hair catcher 37 is removed, the finger is inserted through the receiving port 11 and the plate 21P is pulled upward, and then the plate 21P is moved up and down as shown in FIG. On the other hand, it is installed and the introduction port 22 is in the lower position. Thereafter, the hair catcher 37 is remounted. In this high-speed drainage mode, drainage from the bathtub 3 flows into the receiving chamber 20 from the inlet 22 and then reaches the receiving chamber discharge port 23 when it flows about ¼ round along the peripheral wall 21. A lot of water flows out from the receiving chamber outlet 23 to the sealed chamber 30 as it is. For this reason, the bathtub drainage passes through the receiving chamber 20 at a large flow rate, and the water in the bathtub 3 is discharged in a short time.

  In addition, the vertical change of the plate 21P is easy and can be easily performed even by a general user.

<Second Embodiment>
FIGS. 7 (a) and 8 show a drain trap 10A according to the second embodiment, and show the same cross section as in FIGS. FIG. 7 (b) is a cross-sectional view taken along the line BB of FIG. 7 (a).

  In this embodiment, a plate 21Q is provided instead of the plate 21P of the first embodiment. The plate 21Q has the same configuration except that the inlet 22 is not provided and the length in the vertical direction is shorter than that of the plate 21P.

  The peripheral wall 21 is provided with an opening in which the plate 21Q is engaged so as to be slidable in the vertical direction. The vertical length of the opening is longer than the vertical length of the plate 21Q by the distance from the lower edge of the inlet 22 to the upper end of the plate 21P in the state of FIG. As in the case of the plate 21P, as shown in FIG. 7 (b), the plate 21Q slides in the vertical direction by engaging the ridges 21b on the side surface of the plate 21Q with the ridges 21a on the side surface of the opening of the peripheral wall 21. It is possible.

  Although illustration is omitted, a minute projection is provided on the side surface of the opening portion of the peripheral wall 21, and when the plate 21Q is moved to the uppermost position, the minute projection engages with the side portion at the lower end of the plate 21Q. The plate 21Q is configured to stop at that position even when the finger is released. In addition, you may employ | adopt various locking mechanisms other than a microprotrusion.

  Other configurations of the second embodiment are the same as those of the first embodiment, and the other configurations of FIG. 7 (a) and FIG. 8 are the same as those of FIG. 3 and FIG. The code | symbol has shown the identical part. The circumferential position of the plate 21Q is the same as that of the plate 21P.

  In the second embodiment, when the plate 21Q is positioned at the lowest position as shown in FIG. 7, the inlet 22A is formed on the upper side of the plate 21Q, and the turning mode is set. When the plate 21Q is positioned at the uppermost position as shown in FIG. 8, the introduction port 22B is formed on the lower side of the plate 21Q, and the high speed draining mode is set. The flow of water in the turning mode and the high-speed draining mode is the same as that in the turning mode and the high-speed draining mode of the first embodiment.

<Third Embodiment>
FIGS. 9 and 10 show a drain trap 10B according to the third embodiment, and show the same cross section as in FIGS.

  In the third embodiment, the movable plate 21P is omitted, and the entire circumference of the receiving chamber 20 is surrounded by a circumferential wall 21 that is continuous in the circumferential direction. In this embodiment, a flexible tube (short tube) is provided on the upper portion of the peripheral wall 21 as the introduction port 22C. The introduction port 22C is arranged at the turning mode position of the introduction port 22 (the position of the introduction port 22 in FIG. 3). The introduction port 22 </ b> C extends along the inner peripheral surface of the peripheral wall 21 so that the outflow water flows along the inner peripheral surface of the peripheral wall 21.

  The introduction port 22 </ b> C has a flexibility that allows a person to change the direction of water discharge by touching with a finger and that the direction of water discharge does not change depending on the water flow of the water discharged. Examples of the tube constituting the introduction port 22C include a soft synthetic resin tube embedded with a plastically deformable metal wire.

  Other configurations of the third embodiment are the same as those of the first embodiment, and other reference numerals in FIGS. 9 and 10 indicate the same parts as those in FIGS.

  When the drain trap 10B is set in the turning mode, the inlet 22C is made substantially horizontal as shown in FIG. Thereby, a swirling flow is formed in the upper part of the receiving chamber 20 by the outflow water from the inlet 22C. The flow of water in the receiving chamber 20 in this swirl mode is the same as in the above embodiments.

  When the high-speed drainage mode is set, as shown in FIG. 10, the outflow direction of the introduction port 22C is set obliquely downward toward the receiving chamber discharge port 23. As a result, the effluent water from the introduction port 22 </ b> C flows obliquely downward about ¼ turn along the peripheral wall 21 and then reaches the receiving chamber discharge port 23. Therefore, much of the water that has flowed out of the inlet 22C flows out of the receiving chamber outlet 23 as it is. As a result, the passage flow rate of the receiving chamber 20 increases and the bathtub drainage is discharged in a short time.

The direction of the inner cylinder 50 can be adjusted by turning the cylinder 50.

  Other configurations of the fourth embodiment are the same as those of the first embodiment, and the same reference numerals denote the same parts.

  In order to set the drain trap 10C in the swivel mode, the orientation of the inner cylinder 50 is determined so that the upper introduction port 51 faces the bypass channel 40 as shown in FIGS.

  In this state, the outflow portion 54 faces the receiving chamber discharge port 23 of the peripheral wall 21 and is in an open state, and the lower introduction port 52 and the outflow portion 53 overlap with the peripheral wall 21 and are in a closed state.

  The bathtub drainage from the duct portion 14 flows tangentially into the upper portion of the receiving chamber 20 from the upper inlet 51 as shown in FIG. 15A, and forms a swirling flow in the receiving chamber 20. A hair catcher 37 is immersed in this swirling flow. The water swirling in the receiving chamber 20 descends spirally along the inner peripheral surface of the inner cylinder 50, passes through the outflow portion 54 and the receiving chamber outlet 23 as shown in FIG.

  In this embodiment, the nozzle body 80 is provided with a ring-shaped peripheral plate portion 81, and most of the water flowing out from the discharge port 84 swirls on the peripheral plate portion 81, so that the swirl flow becomes strong.

[High-speed drain mode]
To enter the high-speed drain mode, as shown in FIG. 23, the opening / closing lid 77 is slid to open the bypass port 76 as the second discharge portion. If it does so, the water which flowed in in the water guide member main body 70 from the bathtub drainage flow path 60 will also flow out from the bypass port 76. FIG. Therefore, the amount of water flowing out through the water guide member main body 70 increases, and the bathtub drainage is discharged in a short time.

  Note that the bypass port 76 may be opened and the discharge port 84 may be closed. Thus, it is good also as a high-speed drainage mode by changing the position of the discharge part which flows water into a receiving chamber.

  Each of the above embodiments is an example of the present invention, and the present invention may be configured other than illustrated. For example, in the present invention, the turning mode and the high-speed draining mode may be switched by changing the size of the receiving chamber discharge port.
