Description

  The present invention relates to a drain trap into which both bathtub drainage and washroom drainage are introduced.

  Conventionally, as shown in FIG. 9, in a drain trap disposed at a junction of bathtub drainage and washing ground drainage, a container-shaped trap body 21 is provided under the floor of the washing ground, and a sealing cylinder 22 is disposed in the trap body 21. Then, a bathtub drain pipe 23 for allowing the bathtub drainage to flow into the trap body 21 is connected to the lower side of the trap body 21, and the drain main pipe 24 for draining the bathtub drainage and washroom drainage flowing into the trap body 21 to the external drainage channel 21 is connected to the upper part on the opposite side of the bathtub drain pipe 23, and the washing place and the inside of the trap body 21 are connected via a sealing cylinder 22. The trap body 21 has an inner cylinder 21a connected to the bathtub drain pipe 23 and an outer cylinder 21b arranged coaxially with the inner cylinder 21a and connected to the drain main pipe 24. A sealing cylinder 22 is inserted and arranged.

  In the drain trap as described above, the bathtub drainage flowing in the bathtub drain pipe 23 flows into the inner cylinder 21 a and forms a ring-shaped gap between the inner peripheral surface of the inner cylinder 21 a and the outer peripheral surface of the sealing cylinder 22. It rises, flows into the outer cylinder 21b from the upper end opening of the inner cylinder 21a, and drains through the drain main pipe 24 to the external sewer pipe or the like.

  Further, the wastewater from the washing place descends from the washing place drain 25 into the sealed cylinder 22 and flows into the inner cylinder 21a, and thereafter the inner circumferential surface of the inner cylinder 21a and the outer circumferential surface of the sealed cylinder 22 in the same manner as the bathtub drainage. It is drained to an external sewage pipe or the like through a gap between the outer cylinder 21 and the outer cylinder 21 b and the drain main pipe 24.

  After drainage, the drainage stored in the inner cylinder 21a maintains the state in which the lower end of the sealing cylinder 22 is submerged, the drainage main pipe 24 and the washing place are blocked by this stored water, and drifts from the drainage main pipe 24. It prevents odors and prevents insects from entering the washing area through the main drain.

  However, in the above-mentioned conventional drainage trap, when bathtub drainage and washing ground drainage flow into the trap body at once, a large amount of drainage cannot be drained from the drain main pipe at once, and the drainage near the drain of the outer cylinder of the trap body. A siphon phenomenon may occur in which drainage is performed when the road is full. And when the drainage pressure in the tub or washing area becomes small, the air in the tub or washing area flows into the drainage channel and the siphon phenomenon is interrupted. At this time, the drainage in the drainage channel is drained to the drainage main pipe at once, There may be a squeaking noise in the trap body. For this reason, there was a problem that the user in the bathroom felt uncomfortable.

  In order to solve the above problems, the following drain traps are known.

That is, a float is provided in the inner cylinder, and the receiving member for receiving the float is installed at the washing ground drain outlet. The float moves up and down depending on the water surface height in the inner cylinder, and the water level in the drain trap is high. Then, the float floats up and shuts off the drainage outlet of the washroom, so that the wastewater from the washroom cannot be temporarily flown into the drainage trap, and the drainage stored in the drainage trap can be drained smoothly from the drainage main pipe. It is.
Japanese Utility Model Publication No. 6-8468

  The drain trap which is the invention of Patent Document 1 has the following problems.

  In the drainage trap of the invention of Patent Document 1, when the bathtub drainage and the washing ground drainage flow at the same time, the bathtub has a higher water level than the washing ground, so the bathtub drainage has a stronger water flow, that is, the water pressure becomes higher. Therefore, the bathtub drainage flows into the drain trap preferentially, and when a large amount of the bathtub drainage flows, the water level in the drain trap rises and the float in the inner cylinder rises. Then, the float blocks the washing ground drain, and the drainage in the drain trap does not overflow from the washing ground drain.

  On the other hand, however, since the washing ground drain is blocked, the washing ground drain cannot flow into the drain trap, and the washing ground drain is pooled near the floor where the washing ground drain lid in the bathroom is located. The floor surface wet with a puddle is slippery, dangerous, and uncomfortable.

  Moreover, in the drainage trap of the invention of Patent Document 1, when the water level in the drainage trap rises, the float installed in the inner cylinder rises, the float floats on the receptacle member, and the drainage port of the washing place is blocked. It is said. Here, the float is a floating ball made of a material having a specific gravity smaller than that of water, and the receiving member of the float is made of an elastic material such as rubber. For this reason, once the float is caught in the receiving member, the receiving member and the float are adsorbed and fitted together, and even when the water level drops, the floating member of the receiving member cannot be lowered with the lowering of the water level, There is a possibility that a situation will occur.

  In the state in which the float as described above is fitted to the receiving member, the waste water from the washing place cannot flow into the drain trap. For this reason, the float must be pushed directly outside the bathroom washroom drain, that is, directly on the floor of the washroom, so that the float and the receiving member are separated from each other, so that the washroom drainage can be returned to a normal state. Troublesome things happen.

  The present invention has been made in view of the above matters. The purpose of the present invention is to provide a drainage trap in which both bath drainage and washing ground drainage flow, so that the washing floor drain near the washing ground drain does not become flooded by washing ground drainage. To provide a trap.

  The drain trap of the invention according to claim 1 is provided with a container-shaped trap body into which drainage flows under the floor of a washing place, and a bathtub drain pipe for allowing the drainage of the bathtub to flow into the trap body is connected to the lower side of the trap body. A drainage pipe for draining the washing basin drain and the washing basin drained into the trap body into an external drainage channel, wherein a washing basin drain pipe for allowing the washing ground drainage to flow into the trap body is connected to the upper part of the trap body. In the drainage trap connected to the trap body, a door for closing the bathtub drainage port is provided at a bathtub drainage port corresponding to a connection portion with the bathtub drainage pipe in the trap body, and a float is provided above the door. When the drainage that is connected and stored in the trap body reaches a predetermined amount or more, the float floats, Kitobira is characterized in that closing the tub drain.

  The drain trap of the invention according to claim 2 is connected to the float so that the bar protrudes upward, the bar moves as the float moves up and down, and the door is drained from the bathtub. When the mouth is closed, the end of the bar is located near the lid of the washroom drain provided on the floor of the bathroom.

  According to the drainage trap of the invention according to claim 1, when the bathtub drainage and the washing ground drainage flow into the drain trap, and the drainage stored in the drain trap becomes more than a predetermined amount of water, When the provided float rises by buoyancy, the door provided in the bathtub drainage port can block the bathtub drainage port, and it is possible to prevent the bathtub drainage from flowing into the drain trap excessively. In this case, washing ground drainage can preferentially flow into the trap body, and as a result, it is possible to prevent drainage that has once flowed into the drain trap from overflowing from the washing ground drain to the washing ground floor as much as possible.

  According to the drain trap of the invention according to claim 2, the amount of water in the drain trap increases, the amount of drainage stored in the trap body becomes a predetermined amount or more, and a float provided in the trap body is provided. When the buoyant force is rising, the end of the bar provided on the float rises to the vicinity of the lid of the washroom drain. As a result, the end of the bar that has risen inside the drainage trap can be confirmed by the user at the washing place near the floor of the washing place, and it is confirmed that a large amount of wastewater is stored in the drainage trap. From that, that is, you can know from the washing place. In addition, if a part of the bar is always visible near the floor of the washroom, you can quickly find out that the drain trap is clogged with hair and dirt, making it difficult for the drain to flow through the drain main pipe. The drain trap can be cleaned at an early stage.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

(Embodiment 1)
As illustrated in FIGS. 1 and 2, the drain trap is provided with a container-shaped trap body 2 into which drainage can flow under the floor of the washing place 1, and a sealing cylinder 3 is disposed in the trap body 2, so that the bathtub drain 4 The trap body 2 is connected to the lower portion of the side of the trap body 2 and the drain main pipe 7 for draining the waste water of the bathtub 6 and the washing place 1 flowing into the trap 2 to the external drainage channel. It is connected to the upper part, and the washing place 1 and the inside of the trap body 2 are connected via a sealing cylinder 3. Here, although the connection part with the trap main body 2 of the sealing pipe | tube 3, the bathtub drain pipe 5, and the drain main pipe 7 is normally connected using a connection tool (for example, volt | bolt) etc., these connection tools are sealed. It will be included in a part of the water bottle 3, the bathtub drain pipe 5 and the drain main pipe 7.

  A sliding door 9 that slides up and down is provided on the inner side of the trap body 2 of the bathtub drainage port 8, which is a connection portion with the bathtub drainage pipe 5 in the trap body 2. The door 9 is connected by a connecting member 12 to a float 11 located above the trap body 2 through a guide 10 provided on the inner wall surface of the bathtub drain 8 above the trap body 2. When the amount of drainage stored in the trap body 2 reaches a predetermined amount or more, the float 11 rises in the trap body 2 due to the buoyancy of the drainage. Accordingly, the door 9 connected via the guide 10 is also Ascending and moving, the bathtub drain 8 is closed.

  Here, the amount of water equal to or greater than the predetermined position is the amount of water that the float 11 that has floated due to buoyancy starts to pull up the door 9.

  The door 9 is a plate having a circular shape, and may have a size that can completely cover the bathtub drain 8. However, the shape of the door 9 may be determined according to the shape of the bathtub drain 8. The door 9 may be made of a relatively light material that can be lifted by the buoyancy of the float 11 (for example, rubber).

  The float 11 is preferably formed of a spherical floating ball made of a material having a specific gravity smaller than that of water (for example, a synthetic resin).

  FIG. 3 is a perspective view showing a connecting portion between the door 9 and the rail 13. The door 9 and the float 11 are connected by a connecting member 12 through a guide 10. The door 9 moves along the two rails 13 installed on the inner wall surface of the trap body 2 from the lower end in the trap body 2 to the bathtub drain 8 (FIG. 4). The two rails 13 are arranged on the inner wall surface of the trap body 2 that is next to the bathtub drainage port 8 from the lower end of the trap body 2 to the inside of the guide 10 so that the two rails 13 are substantially parallel to the ground. is set up. As illustrated in FIG. 3, the rail 13 has a U-shape that grips both ends of the plate-shaped door 9, and the two U-shaped rails 13 have a plate-like circular shape. Both edges of the door 9 are fitted and the door 9 moves up and down.

  In order for the door 9 to move on the rail 13 smoothly, it is important that the friction coefficient between the rail 13 and the door 9 is small. Therefore, it is preferable to select a material that does not generate relatively friction between both the rail 13 and the door 9. The distance between the two rails 13 is set somewhat longer than the diameter of the circular door 9 and is positioned substantially perpendicular to the inner wall surface of the trap body 2 of the rail 13 having a U-shape. The width of the surface should be set somewhat wider than the plate thickness of the door 9 so that the friction between the door 9 and the rail 13 is relatively small.

  The door 9 is preferably connected to the float 11 using a relatively light material such as Tegus for the connecting member 12. In that case, the connection member 12 is connected through the guide 10 installed in the inner wall surface of the trap main body 2 above the bathtub drain port 8. The guide 10 is provided with a hole, and the connecting member 12 passes through the hole. The holes play a role of eliminating the shaking in the horizontal direction of the connecting member 12 that moves as the float 11 moves up and down. At this time, the hole of the guide 10 needs to have a hole larger than the maximum diameter of the connecting member 13.

  The connecting method of the door 9 and the float 11 as described above is such that when the drainage stored in the trap body 2 becomes more than a predetermined amount of water and the bathtub drainage port 8 is blocked by the door 9, the bathtub drainage is performed. This is a connecting method in which the door 9 can be sealed with the door 9 without a gap between the door 9 and the bathtub drain 8 so that the door 9 is not blown away by the water pressure into which the door 4 flows. However, the present invention is not limited to this embodiment, and when the drainage stored in the trap body 2 reaches a predetermined amount or more, the door 9 moves smoothly by the floating of the float 11 to cover the bathtub drainage port 8. If the bathtub drainage port 8 is substantially sealed by the door 9 without the door 9 being blown away by the water pressure when the bathtub drainage 4 flows into the trap body 2, the door 9 and the float 11 are hidden. There is no limitation on the connection method.

  Next, based on FIG. 1 and FIGS. 4-6, the usage method of the drain trap of this invention is demonstrated.

  First, the case where the water level in a drain trap is low is demonstrated based on FIG. 1 and FIG. When the water level in the drain trap is low, the amount of drainage passing through the drainage main pipe 7 connected to the trap body 2 is relatively small, and drainage can flow from the bathtub drainage port 8 and the washroom drainage port 14 without any obstacles. Yes, the drain trap will function normally. At this time, since the water level has not reached the height of the float 11, the float 11 is not moved up and down, so the door 9 is not moved, and the bathtub drain 8 is open.

  Next, the case where the water level in the drain trap is high will be described with reference to FIGS. 5 and 6. When the amount of drainage passing through the drainage main pipe 7 connected to the trap body 2 is excessively large, the drainage treatment is not performed smoothly beyond the allowable amount of water that can pass through the drainage main pipe 7. Then, the water level in the trap body 2 gradually increases, the float 11 starts to rise due to buoyancy, and accordingly, the door 9 connected by the connecting member 12 via the guide 10 also starts to rise.

  Here, there are three patterns in which drainage flows into the drain trap. In the first case, only the washing ground drainage 15 flows, in the second case only the bathtub drainage 4 flows, and in the third case both the washing ground drainage 15 and the bathtub drainage 4 flow.

  First, when only the wash basin drainage 15 flows into the drain trap, the wash basin drain 15 excessively flows into the trap body 2 and when the water level in the trap body 2 becomes high, the door 9 is gradually closed by the rise of the float 11. As a result, the bathtub drain 8 is closed. Therefore, drainage does not flow back into the bathtub drain pipe 5. Then, when the drainage of the washing ground drainage 15 into the trap body 2 is finished and the drainage flows out from the drainage main pipe 7, the water level in the trap body 2 begins to drop, the float 11 descends, and the door 9 also moves accordingly. The bathtub drainage port 8 is gradually opened.

  Next, when only the bathtub drainage 4 flows into the drainage trap, the bathtub drainage 4 excessively flows into the trap body 2, and when the water level in the trap body 2 becomes high, the door 9 is gradually closed by the rise of the float 11. As a result, the bathtub drain 8 is closed. Then, the inflow of the bathtub drainage 4 into the trap body 2 is temporarily blocked, and the bathtub drainage 4 flows into the trap body 2 excessively, so that the drainage does not overflow from the washing ground drainage port 14. The door 9 opens and closes depending on the height of the water level, and the degree of opening of the bathtub drain 8 is controlled, so that the trap body 2 is filled with water, but the water level is not higher than that, and the bathtub drains. 4 is finished flowing into the trap body 2 and drainage flows out of the drain main pipe 7, the water level in the trap body 2 begins to fall, the float 11 descends, and the door 9 descends accordingly, and the bathtub The drainage port 8 is also gradually opened.

  Next, when both the bathtub drainage 4 and the washing ground drainage 15 flow into the drainage trap, the bathtub drainage 4 and the washing ground drainage 15 flow into the trap body 2 excessively, and the water level in the trap body 2 becomes high. When the door 9 is gradually closed by the rise of the float 11 and reaches a full water state, the bathtub drain 8 is closed. Then, the inflow of the bathtub drainage 4 into the trap body 2 is temporarily blocked, and the drainage stored in the trap body 2 is drained from the drainage main pipe 7, while only the washroom drainage 15 is in the trap body 2. Will flow into. If the washing ground drainage 15 tries to flow excessively, a water pool is formed in the vicinity of the lid 17 of the washing ground drainage outlet on the floor of the washing ground 1. When the user stops using the water at the washing place 1 and the drainage of the puddle collected in the vicinity of the lid 17 of the washing place drainage flows into the drain trap and the puddle disappears, the water level in the trap body 2 gradually increases. , The float 11 also descends, and the door 9 begins to descend accordingly, the bathtub drain 8 is gradually opened, and the bathtub drain 4 can flow. Since only the bathtub drainage 4 flows from here, it is the same as the case where only the bathtub drainage 4 described above flows into the trap body 2.

(Embodiment 2)
FIG. 7 is a cross-sectional view showing another embodiment when the drain trap is at a low water level, and FIG. 8 is another embodiment at a high water level. While the float 11 moves up and down, the door 9 also moves up and down at the same time. When the trap body 2 is at a high water level, the bathtub drain 8 is closed, and when the water level is low, the bathtub drain 8 is opened. Is the same as in the first embodiment.

  In the present embodiment, a bar 16 is connected above the float 11 and is provided so as to protrude toward the washing ground drain port 14. The washing place drain 14 side of the bar 16 projects slightly from the height of the washing place drain 14 when the water level is low, and a hemispherical marker member 19 is attached to the end. The bar 16 and the marker member 19 can move as the float 11 moves up and down. As illustrated in FIG. 7, when the trap body 2 has a low water level, the float 11 does not move and remains in the vicinity of the washing ground drain port 14, but when the water level becomes high as shown in FIG. 8, The float 11 rises, and the bar 16 and the marker material 18 rise with it, and rise to the vicinity of the lid 17 of the washing ground drainage port. A semi-circular marker material receiving member 19 formed of transparent plastic resin or the like is provided on the lid of the washing place, and the marker material 18 that has risen comes into contact with the marker material receiving member 19 to Appearing on the lid 17, this allows the user of the wash area 1 to detect that the inside of the drain trap is almost full.

  The bar 16 needs to be formed of a relatively light material (for example, synthetic resin) that does not impose a burden on the movement of the float 11. However, the material of the bar 16 is not limited as long as the material has a hardness that can protrude upward. The length of the bar 16 is such that when the amount of water of a predetermined value or more is stored in the trap body 2 and the door of the bathtub drain 8 is closed, the upper surface of the marker material 18 is on the semicircular inner surface of the marker material receiving member 19. It is sufficient that the length is in contact.

  Further, since the marker material 18 comes into contact with the marker material receiving member 19, it may be formed of a soft material (for example, rubber). Moreover, the color of the marker material 18 is good to be formed in colors, such as red from which the user in the washing place 1 can confirm the marker material 18 clearly. However, the material and color of the marker material 18 do not matter as long as the user can easily understand the presence of the marker material 18.

  It is preferable that the marker material receiving member 19 is incorporated in a part of the lid 17 of the washing place drain port, and a semicircular protrusion is provided on the lid 17 of the washing place drain port. However, since the user is barefoot in the washing place 1, if the marker material receiving member 19 has a sharp shape, the foot may be injured. Therefore, the marker material receiving member 19 is preferably a soft material that does not injure the foot, and the contact surface with the foot preferably has a smooth shape. However, the shape does not matter depending on the convenience of the user. The marker material receiving member 19 needs to be made of a transparent material so that the presence of the marker material 18 can be confirmed from the washing place 1 when the marker material 18 contacts the semicircular inner surface of the marker receiving member 19.

  The means for notifying the user using the washing place 1 as described above that the inside of the drain trap is almost full is relatively elaborate. Therefore, when the trap body 2 is full without the marker material 18 and the marker material receiving member 19 being attached, only the bar material 16 is projected upward from the lid 17 of the washroom drain port. It may be a thing.
