  Embodiments of the present invention will be described below with reference to the drawings.

<First Embodiment (FIGS. 1 to 5)>
1 to 3 are schematic cross-sectional views of a drain trap of a bathroom drainage apparatus according to an embodiment installed on a floor of a bathroom, and FIG. 1 shows a state where a bathtub is empty, FIG. 2 is an enlarged view of a part of FIG. 1, and FIG. 3 shows a state in which water is drained from the bathtub. FIG. 4 is a specific perspective view of the bathroom drainage device, and FIG. 5 is a cross-sectional view taken along the line VV of FIG.

  A drainage basin 4 is integrally formed on the bathtub 3 side of the washing pan 2 of the bathroom 1. A drain trap 10 is connected to the drain 4 from below. The drain trap 10 has a substantially cylindrical receiving chamber 11 whose axial direction is the vertical direction.

  An inflow port 12 on the side surface of the receiving chamber 11 and a drain port 3 a on the bottom surface of the bathtub 3 are connected to each other through a connecting portion 5. The inflow port 12 is provided to allow water to flow in the tangential direction with respect to the receiving chamber 11.

  On the upper surface of the receiving chamber 11, there is provided a washing ground drainage inlet 13 through which wastewater from the washing ground pan 2 side flows through the drainage basin 4.

  The drainage basin 4 is formed in a concave shape integrally with the washing place pan 2. A drain pan (not shown) is covered on the upper surface.

  A cylindrical flange member 14 is attached to the opening at the bottom of the drainage tub 4 via a packing (not shown), and the upper end of the drainage trap 10 is attached to the flange member 14 by screwing. Yes. A hair catcher 15 is inserted into the receiving port 13 through the flange member 14 so as to be detachable from above. The outer peripheral side of the upper end of the flange member 14 has a bowl shape, and this bowl portion overlaps the edge of the bottom opening of the drainage bowl 4 from above.

  As clearly shown in FIG. 2, an overhanging portion 14 a is provided on the inner peripheral side of the lower end of the flange member 14. A thrust lock 20 is provided so as to be supported by the overhanging portion 14a.

  The hair catcher 15 has a basket shape with an open upper surface. In this embodiment, the hair catcher 15 has a substantially inverted truncated cone shape that decreases in diameter toward the lower side. The hair catcher 15 is provided with a flange portion 15a on the outer peripheral side of the upper end thereof. The hair catcher 15 is arranged so that the collar portion 15 a moves up and down along the inner peripheral surface of the flange member 14.

  The thrust lock 20 includes a cylinder portion 20a and a rod 20b. A thrust lock mechanism is provided in the cylinder portion 20a. When the rod portion 20b is pushed, the rod portion 20b is locked at the pushed position, and when the rod portion 20b is pushed once more, the rod portion 20b is It is configured to be pushed upward by a spring (not shown) in the cylinder portion 20a and protrude upward. Such a thrust lock is well known as described in JP-A-9-203095, and various types are commercially available.

  A plurality of the thrust locks 20 are installed at equal intervals along the inner periphery of the flange member 14 so that the rod portion 20b protrudes upward.

  The tip of the rod portion 20b is in contact with the lower surface side of the collar portion 15a of the hair catcher 15, and supports the hair catcher 15. Therefore, when the hair catcher 15 is pushed in from above, the hair catcher 15 takes the lowered position of FIG. 3, and when pushed again, the hair catcher 15 takes the raised position of FIGS. The level difference between the raised position and the lowered position of the hair catcher 15 is preferably about 5 to 50 mm, particularly about 10 to 30 mm.

  As clearly shown in FIGS. 1 and 3, an outlet 16 is provided at the center of the bottom surface of the receiving chamber 11. The diameter of the outlet 16 is smaller than the inner diameter of the receiving chamber 11. An outflow chamber 17 is provided from the lower side to the side surface of the receiving chamber 11.

  In this embodiment, the outflow chamber 17 is provided on the side opposite to the inflow port 12, but is not limited thereto. The outflow chamber 17 rises above the sealing surface W along the outer surface of the receiving chamber 11. A drain pipe connecting portion 18 serving as a drain channel is connected to the upper portion of the outflow chamber 17. A drain pipe 19 is connected to the drain pipe connecting portion 18. The level of the bottom surface of the drain pipe connecting portion 18 is a sealing surface W.

  Vent pipes 24 and 25 are provided so as to communicate between the outflow chamber 17 and the bathroom. The vent pipe 25 is provided integrally with the hair catcher 15 in the vertical direction. The lower end of the vent pipe 25 is detachably fitted to the upper end of the vent pipe 24. The ventilation pipe 24 extends from the inside of the receiving chamber 11 into the outflow chamber 17 through its side peripheral wall. The lower end portion of the vent pipe 24 has a large-diameter cylindrical shape, and a plurality of small holes 24a are provided on the bottom surface. When water flows into the outflow chamber 17, bubbles are mixed into the flowing water through the vent pipes 24 and 25.

  In addition, even if the swirling flow in the receiving chamber 17 acts on the hair catcher 15 by fitting the vent pipes 24 and 25, the hair catcher 15 does not swirl.

  Next, the operation of the drain trap configured as described above will be described.

  When draining water from the tub 3 filled with water, the hair catcher 15 is pushed in so as to be lowered as shown in FIG. 3, and the drain plug of the drain port 3a is pulled out. Then, the water in the bathtub 3 flows into the receiving chamber 11 of the drain trap 10 from the inlet 12, and forms a spiral swirl flow in the receiving chamber 11. The water level in the receiving chamber 11 gradually rises, and the hair catcher 15 or the drainage basin 4 is in a state of being submerged in the swirling flow. As a result, dust adhering to the inner surface of the drainage tub 4 and the hair catcher 15 is scraped off, and dust such as hair is collected at the center of the vortex and is favorably collected at the center of the bottom surface of the hair catcher 15.

  In this embodiment, since the hair catcher 15 is deeply immersed in water, the dust adhering to the hair catcher 15 is sufficiently scraped off, and the dust is collected very efficiently in the center of the bottom surface of the hair catcher 15. It is done.

  A part of the water swirling in the receiving chamber 11 flows out from the vicinity of the center of the vortex to the drain pipe 19 through the outlet 16 at the center of the bottom of the receiving chamber 11, the outflow chamber 17 and the drain pipe connecting portion 18.

  When water flows into the outflow chamber 17, bubbles are mixed into the flowing water through the vent pipes 25 and 24 and the small holes 24a. Thereby, the negative pressure generated in the drain pipe 19 is reduced. As a result, almost all of the water in the outflow chamber 17 of the drain trap 10 is prevented from being sucked out to the drain pipe 19 and the drain trap is broken.

  In this embodiment, the spiral swirling flow in the receiving chamber 11 flows out to the outflow chamber 17 through the small-diameter outlet 16. In the vicinity of the outlet 16, the swirl radius is smaller than the swirl radius in the receiving chamber 11, so the swirl flow velocity is large. As a result, the swirling flow in the receiving chamber 11 also becomes high speed accompanying the high swirling flow velocity in the vicinity of the outlet 16. Therefore, even when the water level of the bathtub 3 is low and the inflow velocity from the inlet 12 is small, a strong swirling flow is formed in the receiving chamber 11 and the hair catcher 15 and the drainage tub 4 are sufficiently washed. Moreover, dust is efficiently collected at the center of the hair catcher 15.

  When all the water flows out from the bathtub 3, the swirling flow stops and the sealed water at the level of the sealing surface W remains in the drain trap 10. Further, water also flows into the ventilation pipe 24 from the small hole 24 a, and sealing water exists in the ventilation pipe 24 up to the sealing surface W.

  Thereby, both the drain pipe 19 side and the washing place and the bathtub 3 side are isolated by the sealed water, and the odor of the drain pipe 19 is prevented from flowing back to the washing place and the bathtub 3.

  After the drainage from the bathtub 3 is finished in this way, the hair catcher 15 is pressed downward and then released, and the rod 20b of the thrust lock 20 is projected to raise the hair catcher 15. As a result, as shown in FIGS. 1 and 2, the lower end of the hair catcher 15 is higher than the sealing surface W, so that the hair catcher 15 dries and prevents slime and the like. In addition, the hair catcher 15 can be taken out by picking the ventilation pipe 25, and garbage can be thrown away.

<Second Embodiment (FIG. 6)>
FIG. 6 is a longitudinal sectional view of a drain trap 10A of a bathroom drain device according to another embodiment.

  In this embodiment, a pop-up drain plug device 30 is provided at the drain port 3 a of the bathtub 3. The drain plug device 30 includes a plug body 31 that comes into contact with and separates from a drain port from above, a release wire 32 for moving the plug body 31 up and down, and an operation portion 34 thereof.

The upper end of the rod 39 a is in contact with the center of the bottom surface of the hair catcher 15.

  As shown in FIG. 6, when the plug 31 is in the closed state, the lifting device 39 is locked with the rod 39a protruding upward, so that the hair catcher 15 is supported by the rod 39a. Has been raised. When the button 34a of the operation unit 34 is pressed once, the lock of the rod 39a is released, the rod 39a is retracted downward, and the hair catcher 15 is lowered by its own weight. At this time, the plug 31 is opened. When the button 34a is pushed once more, the rod 39a protrudes upward, and the hair catcher 15 is pushed up to the raised position. At this time, the plug 31 is closed.

  In this embodiment, the thrust lock 20 shown in FIGS. 1 to 5 is not provided between the flange member 14 and the hair catcher 15. The vertical movement of the hair catcher 15 is guided by sliding between the vent pipes 25 and 24.

  The other configurations in FIG. 6 are the same as those in FIGS. 1 to 5, and the same reference numerals denote the same parts.

  Next, the operation of the drain trap 10A configured as described above will be described.

  FIG. 6 shows a state in which the bathtub 3 is filled with water, the plug 31 is closed, and the hair catcher 15 is in the raised position. At this time, the hair catcher 15 is located above the sealing surface W of the drain trap 10A.

  When the button 34 a is pushed to drain from the bathtub 3, the plug 31 is raised and opened, and the hair catcher 15 is lowered to form a swirling flow in the receiving chamber 11. Since the hair catcher 15 is deeply immersed in water, dust is efficiently collected at the center of the bottom surface in the hair catcher 15 as in the case of FIGS.

  After draining from the bathtub 3, the button 34a is pushed once more. Then, the plug body 31 descends and closes, and the hair catcher 15 rises and is positioned higher than the sealing surface W as shown in FIG.

  In this embodiment, since the drain plug body 31 is raised and lowered and the hair catcher 15 is lowered and raised together by the operation portion 34, the hair catcher 15 is interlocked with the drainage operation from the bathtub 3. The hair catcher 15 always takes the lowered position when the bathtub is drained. For this reason, the separate operation for lowering the hair catcher 15 at the time of bathtub drainage is unnecessary, and it is convenient.

<Modification of Second Embodiment (FIGS. 7 and 8)>
FIGS. 7 and 8 are longitudinal sectional views of a drain trap 10A ′ of a bathroom drain device according to a modification of the second embodiment. FIG. 7 shows an empty state of the bathtub, and FIG. 8 shows the bathtub. It shows the state of draining from.

  In the embodiment of FIG. 6, the hair catcher 15 is lowered and raised by the lifting device 39 having a thrust lock mechanism in conjunction with the raising and lowering of the drain plug 31, but the lifting mechanism of the hair catcher 15 is It is not limited to this.

  For example, the hair catcher 15 may be moved up and down by the lever mechanism 60 as in the drainage trap 10A 'shown in FIGS.

  The lever mechanism 60 includes a lever 61 that is supported by a shaft support portion 62 provided in the receiving chamber 11 and is installed to be rotatable in the vertical direction. The lever 61 is supported by a shaft support portion 62 in the middle in the longitudinal direction. The front end side of the lever 61 extends to the vicinity of the center of the receiving chamber 11 and rises upward from the center of the receiving chamber 11 to form a rising portion 61a. The upper end of the upright portion 61 a is in contact with the center of the bottom surface of the hair catcher 15.

  In this embodiment, a release wire 38 is connected from the operation unit 34 to the rear end of the lever 61. The core member 38a of the release wire 38 protrudes upward from the guide tube 38b, and its tip is connected to the rear end of the lever 61 via a hinge (not shown) so as to be rotatable in the extending direction of the lever 61. ing. The guide cylinder 38b is fixedly installed in the receiving chamber 11 below the rear end of the lever 61 with the cylinder axis direction being a substantially vertical direction.

  Other configurations in FIGS. 7 and 8 are the same as those in FIG. 6, and the same reference numerals denote the same parts.

  The operation direction of the drain trap 10A 'configured in this way is the same as that of the drain trap 10A of FIG.

  That is, when the button 34a of the operation unit 34 is pushed to discharge the water from the state in which the water is filled in the bathtub 3 as shown in FIG. 7, the tip of the core member 32a of the release wire 32 protrudes upward, and the plug The body 31 is pushed up and opened. Further, the leading end of the core member 38a of the release wire 38 also protrudes upward and pushes up the rear end of the lever 61. As a result, as shown in FIG. 8, the rising portion 61a on the tip end side of the lever 61 is lowered, and the hair catcher 15 is lowered by its own weight. At this time, the button 34a is locked in the pushing position, and this state continues until the button 34a is pushed again.

  Thereby, drainage of water from bathtub 3 is performed. This water flows into the receiving chamber 11, and a swirling flow is formed in the receiving chamber 11. Since the hair catcher 15 is deeply immersed in this swirling flow, dust is efficiently collected at the center of the bottom surface in the hair catcher 15.

  After draining from the bathtub 3, the button 34a is pushed once more. If it does so, the button 34a will raise, the core material 32a of the release wire 32 will recede, the plug 31 will descend | fall, and it will plug. Further, the core member 38a of the release wire 38 is also retracted, and the rear end of the lever 61 is pulled down. As a result, as shown in FIG. 7, the front end side of the lever 61 is raised, and the hair catcher 15 is pushed up to the raised position by the upright portion 61a and is positioned above the sealing surface W.

  Even in this embodiment, since the drain plug body 31 is raised and lowered and the hair catcher 15 is lowered and raised together by the operation unit 34, the hair catcher 15 is interlocked with the drainage operation from the bathtub 3. The hair catcher 15 always takes the lowered position when the bathtub is drained. For this reason, the separate operation for lowering the hair catcher 15 at the time of bathtub drainage is unnecessary, and it is convenient.

  Other configurations in FIG. 11 are the same as those in FIGS. 1 to 5, and the same reference numerals indicate the same parts.

  Next, the operation of the drain trap 10C configured as described above will be described.

  FIG. 11 shows a state in which the bathtub 3 is empty, and the float 50 floats on the sealing surface W. At this time, the hair catcher 15 is located above the sealing surface W of the drain trap 10C.

  When the drain plug is pulled out from the bathtub 3 filled with water, the water level in the outflow chamber 17 rises, the float 50 rises, and the upright portion 51a of the lever 51 falls. As a result, the hair catcher 15 descends due to its own weight and is immersed deeply in the receiving chamber 11. By soaking the hair catcher 15 deeply in the water in this way, dust is efficiently collected at the center of the bottom surface in the hair catcher 15 as in the case of FIGS.

  After the drainage from the bathtub 3 is finished, the water level in the outflow chamber 17 is lowered to the sealing surface W, so that the rising portion 51a of the lever 51 rises and the hair catcher 15 is moved from the sealing surface W as shown in FIG. Also rises to the top.

  In this embodiment, the float 50 is raised by the water level of the outflow chamber 17 that rises with the start of drainage from the bathtub 3, and the hair catcher 15 is lowered. It comes to take. For this reason, the separate operation for lowering the hair catcher 15 at the time of bathtub drainage is unnecessary, and it is convenient.
