Description

The present invention relates to a drain trap device having a trap structure for flowing drainage from drains provided in a bathtub and a washing place in a bathroom to a water distribution pipe and preventing odors and small animals from entering the bathroom from the water distribution pipe.

Generally, in a bathroom, a drainage channel for drainage from a bathtub and a drainage channel for drainage from a washing place are combined by a drainage trap device embedded under the pan and drained into a drainage pipe of a building. In addition, a drain trap device that can realize a trap structure that collects and seals water between the water pipe and the drain in the bathroom is used so that odors and small animals cannot enter the bathroom from the water pipe of the building. ing.

As an example of the drain trap device, there is one configured by a first drain trap body on the bathtub side, a second drain trap body on the washing place side, and a communication route communicating these. The communication path has a structure in which the outflow portion of the first drain trap body and the inflow portion of the second drain trap body are brought close to each other facing each other, and the short separation section is connected by a communication pipe having a bellows-like flexibility (the communication path). For example, see paragraphs [0015] [0031] [0032], FIGS. 1, 2, etc. of Patent Document 1).

According to the drainage trap device described in Patent Document 1, the drainage flowing from the drainage port on the bathtub side or the drainage port on the washing place side flows into the first drainage trap body and the water storage vacant portion provided inside the second drainage trap body. When the water level exceeds the reference water level that accumulates and reaches the lower end of the drainage outlet connected to the water distribution pipe, it overflows and is discharged from the drainage outlet to the water distribution pipe. Normally, the inside of the water storage vacant part and the communication pipe of the first drain trap body and the second drain trap body are filled with the amount of sealing water that becomes the reference water level, so that odors, small animals, etc. from the water distribution pipe are in the bathroom. A trap structure is retained that prevents entry into.

However, in the invention described in Patent Document 1, if there is a deviation in which the outflow portion of the first drain trap body and the inflow portion of the second drain trap body cannot be arranged in a straight line facing each other, the deviation occurs. Can not be absorbed due to the flexibility of the communication pipe, and it may not be possible to attach a drain trap device. For example, the height of the part where the drainage port is provided on the bathroom side pan, the height of the part where the drainage port is provided on the washroom side pan, the positional relationship between the drainage port provided on the bathroom side pan and the drainage port provided on the washroom side pan, and the separation distance. Since the unified standard is not strictly defined, it varies depending on the pan to be attached, and the first drain trap body and the second drain trap body may not always be attached in the ideal state.

The outflow part of the first drain trap body and the inflow part of the second drain trap body cannot be arranged in a straight line facing each other, and moreover, the outflow part of the first drain trap body and the inflow of the second drain trap body When the separation distance from the part is short, even if a soft material such as a rubber hose is used for the communication pipe, the outflow part of the first drain trap body and the inflow part of the second drain trap body can be maintained while maintaining a sufficient running water cross section. It is difficult to connect. Furthermore, when a flexible hose made by corrugating a stainless steel pipe to give flexibility is used as a communication pipe, the separation between the outflow portion of the first drain trap body and the inflow portion of the second drain trap body is appropriate. If the distance is not secured, it is difficult to absorb and connect the deviation between the outflow portion of the first drain trap body and the inflow portion of the second drain trap body.

Therefore, in the present invention, when the mounting positions of the first drain trap body and the second drain trap body are displaced within an allowable range, the flexible connecting body absorbs the displacement and the first drain trap body is displaced. It is an object of the present invention to provide a drain trap device capable of connecting the trap body and the second trap body.

In order to solve the above problem, the first aspect of the invention according to claim 1 is to form a drain port having a trap structure, which is attached to a drainage through hole of a pan on the tub side and collects sealed water up to a predetermined height of a water storage vacant portion. It is attached to the drain trap body and the drain through hole of the washing place side pan provided near the drain through hole of the tub side pan to form a drain port of a trap structure in which the sealed water is collected up to a predetermined height of the water storage vacant space. The second drain trap body for communicating the water storage vacant part with the water distribution pipe, and the drainage communication means for connecting the water storage vacant part of the first drain trap body and the water storage vacant part of the second drain trap body are provided. In the drain trap device, the drain communication means is different from the proximity direction in which the first drain trap body and the second drain trap body face the water storage vacant portion of the first drain trap body and / or the second drain trap body. A water passage hole is provided so as to communicate with the water passage hole of the first drain trap body and / or the second drain trap body, and a pipe joint that protrudes outward and faces in a close direction is provided, and the pipe joints are separated from each other. The distance or the separation distance between the connecting pipe protruding outward from the water passage hole provided in the water storage space and the pipe joint is set to a length that can be connected by the hollow flexible connecting body. It is a feature.

Further, according to the second aspect of the present invention, in the drainage trap device according to the first aspect, the first drain trap body and / or the second drain trap body corresponds to the vicinity of the drainage through hole from the lower surface side of the pan. An annular contact surface of the main body side flange portion is provided with a main body side flange portion having an annular contact surface having a required width to be worn, and a fixed flange member attached and fixed to the main body side flange portion from the upper surface side of the pan. By interposing a spacer of the required thickness between the bottom of the pan and the bottom of the pan, the empty storage space of the first drain trap body attached to the bath side pan and the water storage empty of the second drain trap body attached to the washing area side pan. The feature is that the relative height with the part can be adjusted.

Further, according to the third aspect of the present invention, in the drain trap device according to the second aspect, the spacer is an upper surface that is pressed against the lower surface side of the pan and / or a lower surface that is pressed against the annular contact surface of the flange portion on the main body side. It is characterized by having a sealed structure.

Further, the invention according to claim 4 extends downward from the outside of the lower surface of the drain trap device according to claim 2 or 3, where the spacer is pressed against the annular contact surface of the flange portion on the main body side. It is characterized in that a holding portion to be pulled out is provided, and the holding portion of the spacer is fitted to the upper part of the outer periphery of the flange portion on the main body side to prevent the spacer from falling off from the flange portion on the main body side.

According to the drain trap device according to the present invention, a pipe joint is provided in the first drain trap body and / or the second drain trap body, and is outward from the separation distance between the pipe joints or the water passage hole provided in the water storage vacant portion. Since the separation distance between the connecting pipe protruding from the pipe and the pipe joint is set to a length that can be connected by the hollow flexible connecting body, the mounting position of the first drain trap body and the second drain trap body is set. If the deviation is within the allowable range, the deviation can be absorbed by the flexible connecting body, and the first discharge trap body and the second discharge trap body can be connected.

Hereinafter, embodiments of the drain trap device according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show a schematic configuration of the drain trap device 1, in which a flexible hose 30 (first drain trap), which is a hollow flexible connection between the first drain trap body 10 and the second drain trap body 20, is shown. Only the connecting portion 31 to the body 10 and the connecting portion 32 to the second discharge top body 20 are drawn, and the space between them is simply shown by a two-point chain line).

The first drain trap body 10 is attached to the drain through hole 41a provided at the lowest portion of the bathtub side pan 41, and can be separated into the trap main body 11 and the fixed flange member 12. When the first drain trap body 10 is attached to the bathtub side pan 41, a rubber packing 13 as a sealing material is fitted into the opening edge of the drain through hole 41a in order to improve its sealing performance.

The trap body 11 of the first drain trap body 10 is formed from a bowl-shaped bottomed hemisphere in which a water storage space 111a capable of storing drainage is formed, and from the circular upper end of the water storage part 111. A ring-shaped flange portion 112 extending in the lateral direction and a connecting pipe 113 communicating with a water passage hole 111b provided at an appropriate position of the water storage portion 111 and projecting outward are provided. For example, a female screw portion 111c is formed on the upper inner peripheral surface of the water storage portion 111. Further, the upper surface of the flange portion 112 on the main body side is an annular contact surface having a required width for contacting the periphery of the lower surface side of the drainage through hole 41a.

The fixed flange member 12 of the first drain trap body 10 has a screwed cylindrical portion 121 having a male screw portion 121a screwed to the female screw portion 111c of the trap body 11 formed on the outer peripheral surface thereof, and the screwed cylindrical portion 121. A ring-shaped fixed side flange portion 122 extending laterally from the upper end of the circle is provided. The lower surface of the fixed-side flange portion 122 is an annular contact surface having a required width for contacting the periphery of the upper surface side of the drainage through hole 41a. A removable drainage lid 123 is attached to the inner space 12a of the fixed flange member 12, and water or hot water in the bathtub is drained from the hole provided in the drainage lid 123.

In order to attach the first drain trap body 10 having the above structure to the bathtub side pan 41, from the lower surface side of the bathtub side pan 41 to the periphery of the lower surface of the drainage through hole 41a (the lower surface of the rubber packing 13), the main body side of the trap body 11 The annular contact surface of the flange portion 112 is abutted, and the screwed cylindrical portion 121 of the fixed flange member 12 is passed through the drainage through hole 41a (inner space portion of the rubber packing 13) from the upper surface side of the bathtub side pan 41. The male threaded portion 121a of the fixed flange member 12 is screwed into the female threaded portion 111c of the trap body 11, and the fixed flange member is formed around the upper surface of the drainage through hole 41a (upper surface of the rubber packing 13) from the upper surface side of the bathtub side pan 41. The annular contact surface of the fixed side flange portion 122 of 12 is brought into contact. Then, when the fixed flange member 12 is attached to the trap body 11 so that the sealing function of the rubber packing 13 works sufficiently, all the drainage from the bathtub side pan 41 flows into the water storage portion 111 of the first drain trap body 10. A drain on the bathtub side is formed. A sliding ring 14 having good sliding property with respect to the material of the fixed side flange portion 122 is interposed between the upper surface of the rubber packing 13 and the annular contact surface of the fixed side flange portion 122. By doing so, since the annular contact surface of the fixed side flange portion 122 does not directly hit the rubber packing 13 having a large contact resistance, it is possible to efficiently perform the work of screwing the fixed flange member 12 to the trap body 11. Will be.

On the other hand, the second drain trap body 20 is attached to the drain through hole 42a provided at the lowest portion of the washing place side pan 42, and can be separated into the trap main body 21 and the fixed flange member 22. When the second drain trap body 20 is attached to the washing place side pan 42, a rubber packing 23 as a sealing material is fitted into the opening edge of the drain through hole 42a in order to improve the sealing property. Further, the drainage through hole 42a of the washing place side pan 42 is provided in the vicinity of the drainage through hole 41a of the bathtub side pan 41, and the first trap body 10 is close to the second trap body 20 in the proximity direction D1. , The second trap main body 20 comes close to the first trap main body 10 in the proximity direction D2.

The trap main body 21 of the second drain trap body 20 has a water storage portion 211 forming a water storage empty portion 211a capable of storing drainage inside, and a rim-shaped main body appropriately protruding upward from an appropriate position above the water storage portion 211. A side flange portion 212 and a bulging-shaped connecting body 213 that projects an appropriate position of the water storage portion 211 outward are provided. For example, a water passage hole 211b is provided on the protruding side end surface of the connecting body 213.

The water storage unit 211 forms a water storage space 211a that can secure a larger water storage capacity than the water storage space 11a of the first drain trap body 10. For example, the cross section of the water storage space 211a is substantially square. It has four sides. Specifically, the opposite side of the substantially vertical facing surface 211-1 facing the first drain trap body 10, the substantially vertical first side surface 211-2 provided with the water passage hole 211b, and the first side surface 211-2. It is composed of a second side surface 211-3 in a substantially vertical direction located in the vertical direction, and a drainage tapered surface 211-4 located on the opposite side of the facing surface 211-1 and inclined so as to be away from the facing surface 211-1.

The space above the upper end of the drainage tapered surface 211-4 functions as a drainage outlet 211c and communicates with the drainage outlet passage 214a of the water distribution pipe connection portion 214. The drainage outlet path 214a of the water distribution pipe connection portion 214 is inclined downward from the drainage outlet port 211c, and the water in the water storage vacant portion 211a exceeding the reference water level WL reaching the upper end of the drainage tapered surface 211-4 overflows. It reaches the drainage outlet path 214a and is discharged to the water distribution pipe (not shown). It is desirable that the water passage hole 211b is provided at a position where the upper edge of the opening does not exceed the reference water level WL. Further, if the water passage holes 211b are provided in a plurality of locations (for example, the facing surface 211-1 and the second side surface 211-3) in advance, the positions are easy to use according to the connection position between the water distribution pipe connecting portion 214 and the water distribution pipe. It is also possible to leave only the water passage holes in the above and seal unnecessary water passage holes with a sealing member.

The main body side flange portion 212 is a hollow cylindrical body having an annular outer peripheral surface 212a that appropriately protrudes upward from the top plate portion 211-5 of the water storage portion 211, and the upper end thereof is for draining the washing place side pan 42. An annular contact surface 212b having a required width for contacting is provided around the lower surface side of the through hole 42a. Further, a female screw portion 212c is formed on the inner peripheral surface which is connected to the inner edge of the annular contact surface 212b and extends downward. In FIG. 1, a spacer packing 50 (detailed later) is attached to the flange portion 212 on the main body side, and the spacer packing 50 is attached to the vicinity of the lower surface side of the drainage through hole 42a of the washing place side pan 42. However, whether or not to use the spacer packing 50 is appropriately determined according to the situation at the time of mounting, as will be described later. Further, a substantially cylindrical trap cylinder 215 is attached to the lower part of the inner circumference of the flange portion 212 on the main body side, and if the sealing water is accumulated above the predetermined water level in the water storage empty portion 211a, the lower part of the trap cylinder 215 is inside the sealing water. It will be in a state of deeply entering.

The fixed flange member 22 of the second drain trap body 20 has a screwed cylindrical portion 221 having a male screw portion 221a screwed to a female screw portion 212c formed on the inner peripheral surface of the main body side flange portion 212 formed on the outer peripheral surface. A ring flange-shaped fixed side flange portion 222 extending laterally from the circular upper end of the screwed cylindrical portion 221 is provided. The lower surface of the fixed-side flange portion 222 is an annular contact surface having a required width to be in contact with the periphery of the upper surface side of the drainage through hole 42a. Further, a removable drainage lid may be attached so as to close the upper surface opening of the inner space 22a of the fixed flange member 22.

In order to attach the second drain trap body 20 having the above structure to the washing place side pan 42, the trap main body side is located around the lower surface of the drainage through hole 42a (the lower surface of the rubber packing 23) from the lower surface side of the washing place side pan 42. The annular contact surface of the flange portion 212 is abutted to 212b, and the screwed cylindrical portion 221 of the fixed flange member 22 is passed through the drainage through hole 42a (inner space portion of the rubber packing 23) from the upper surface side of the washing place side pan 42. , The male screw portion 221a of the fixing flange member 22 is screwed into the female screw portion 212c of the trap body 21, and the fixing flange is attached to the vicinity of the upper surface of the drainage through hole 42a (upper surface of the rubber packing 23) from the upper surface side of the washing area side pan 42. The annular contact surface of the fixed side flange portion 222 of the member 22 is attached. Then, when the fixed flange member 22 is attached to the trap body 21 so that the sealing function of the rubber packing 23 works sufficiently, all the drainage from the washing place side pan 42 flows into the water storage portion 211 of the second drain trap body 20. A drain on the washing place side is formed. A sliding ring 24 having good sliding property with respect to the material of the fixed side flange portion 222 is interposed between the upper surface of the rubber packing 23 and the annular contact surface of the fixed side flange portion 222. By doing so, since the annular contact surface of the fixed side flange portion 222 does not directly hit the rubber packing 23 having a large contact resistance, it is possible to efficiently perform the work of screwing the fixed flange member 22 to the trap body 21. Will be.

Next, with reference to FIGS. 1 to 3, a drainage communication means for connecting the water storage vacant portion 11a of the first drain trap body 10 and the water storage vacant portion 211a of the second drain trap body 20 will be described.

The trap body 11 of the first drain trap 10 positions the water passage hole 111b in a direction orthogonal to the proximity direction D1 (for example, a direction rotated 90 ° to the left toward D1). In this way, the connecting pipe 113 extends in the direction of L90 ° with respect to the proximity direction D1 (connecting direction C1), and the first elbow 61 is attached to the connecting pipe 113. The connecting pipe 113 and the first elbow 61 are connected so as not to cause water leakage. The first elbow 61 is a pipe joint whose direction changes by 90 ° while projecting in a curved shape from the first connecting port 61a to the second connecting port 61b, and connects the first connecting port 61a side to the connecting pipe 113 of the trap body 11. Then, the second connecting port 61b opens toward the proximity direction D1. Since the first elbow 61 changes in a curved shape with an appropriate curvature, the position of the second connecting port 61b is opened at a position appropriately separated from the first connecting port 61a in the C1 direction.

The trap body 21 of the second drain trap 20 positions the water passage hole 211b in a direction orthogonal to the proximity direction D2 (for example, a direction rotated 90 ° to the right toward D2). In this way, the connecting body 213 extends in the direction of R90 ° (connecting direction C2) with respect to the proximity direction D2, and the elbow socket 70 is provided on the protruding side end surface of the connecting body 213, and the elbow socket 70 The second elbow 62 is attached via the connecting portion 71. The elbow socket 70 forms a water passage from the water passage hole 211b of the trap main body 21 to the connecting portion 71, and maintains a hermeticity that does not cause water leakage at the connection portion with the water passage hole 211b. Further, the connecting portion 71 of the elbow socket 70 and the second elbow 62 are also connected so as not to cause water leakage. The second elbow 62 is a pipe joint whose direction changes by 90 ° in a bent shape from the first connecting port 62a to the second connecting port 62b, and when the first connecting port 62a side is connected to the connecting portion 71 of the elbow socket 70, The second connecting port 62b opens toward the proximity direction D2. Since the second elbow 62 bends in the D2 direction with a relatively small amount of protrusion, the position of the second connecting port 62b opens at a position relatively close to the first connecting port 62a in the C1 direction.

In the second drain trap 20 described above, a connecting body 213 that bulges in the C2 direction from the first side surface 211-2 located on the connecting direction C2 side is provided, and an elbow socket 70 is further provided on the protruding side end surface of the connecting body 213. By providing it, the protrusion distance in the C2 direction from the first side surface 211-2 to the portion where the second elbow 62 is attached is lengthened, and the second connecting port 61b of the first elbow 61 provided in the first drain trap 10 and the second connecting port 61b. The second connecting port 62b of the 2 elbow 62 was made to face each other moderately. However, the method for adjusting the relative position between the second connecting port 61b of the first elbow 61 and the second connecting port 62b of the second elbow 62 is not limited to this. For example, a water passage hole 211b is directly provided on the flat first side surface 211-2 to form a long connecting pipe extending in the C2 direction from the water passage hole 211b, and a first connecting pipe is formed on the extending end side of the connecting pipe. 2 The structure may be such that the first connecting port 62a of the elbow 62 is attached (similar to the connecting pipe 113 of the first drain trap 20).

FIG. 3A shows a case where the first drain trap body 10 and the second drain trap body 20 are in an ideal arrangement when the drain trap device 1 is attached to the bath side pan 41 and the washing place side pan 42. For example, an ideal mounting state in which the virtual center line passing through the center of 12 openings in the first drain trap body 10 and the virtual center line passing through the center of 22 openings in the second drain trap body 20 are aligned. It is in.

As described above, if the mounting positions of the first drain trap body 10 and the second drain trap body 20 are ideally arranged, the virtual connecting pipe 101 projecting in the D1 direction as in the conventional drain trap device (FIG. 3 (a) to (c) shown by a two-point chain line) is provided in the first drain trap body 10 and is projected in the D2 direction. (Shown) is provided in the second drain trap body 20, but the virtual connecting pipe 101 of the first drain trap body 10 and the virtual connecting pipe 201 of the second drain trap body 20 are arranged so as to face each other with almost no deviation. Therefore, even if the separation distance between the virtual connecting pipe 101 and the virtual connecting pipe 201 is short, the virtual connecting pipe 101 and the virtual connecting pipe 201 can be connected without difficulty by using the flexible hose 30.

Further, as in the drain trap device 1 according to the present embodiment, the first drain trap body 10 is projected in the C1 direction from the substantially center of the inner space 12a (a position appropriately distant from the tip on the proximity side in the anti-proximity direction). The first drain trap body 10 in which the first elbow 61 is connected to the connecting pipe 113 and the drain taper surface in the second drain trap body 20 behind the center of the inner space 22a (the drain taper surface in the anti-proximity direction from the facing surface 211-1). Even when the drain trap body 20 to which the second elbow 62 is connected is connected to the elbow socket 70 provided so that the connecting portion 71 protrudes in the C2 direction from the position (appropriately separated from 211-4), the first elbow 61 Since the second connecting port 61b and the second connecting port 62b of the second elbow 62 are arranged so as to face each other in the D1 and D2 directions, the first elbow 61 and the second elbow 62 can be reasonably connected by using the flexible hose 30. You can connect. Moreover, a sufficient distance can be secured between the second connecting port 61b of the first elbow 61 and the second connecting port 62b of the second elbow 62.

FIG. 3B shows C1 and C2 from the ideal mounting positions of the first drain trap body 10 and the second drain trap body 20 when the drain trap device 1 is attached to the bathtub side pan 41 and the washing place side pan 42. It shows the case where the deviation occurs by α in the direction. In this case, in order to connect the virtual connecting pipe 101 and the virtual connecting pipe 201 using the flexible hose 30 as in the conventional drain trap device, the flexibility of the flexible hose 30 causes a deviation α in the C1 and C2 directions. It is necessary that the virtual connecting pipe 101 and the virtual connecting pipe 201 are separated to the extent that they can be absorbed. However, since the virtual connecting pipe 101 and the virtual connecting pipe 201 project in the proximity directions D1 and D2, respectively, it is not possible to secure a separation distance longer than the length required for connecting with the flexible hose 30, and the flexible hose. It is difficult to reasonably connect the virtual connecting pipe 101 and the virtual connecting pipe 201 using the 30.

On the other hand, in the drain trap device 1 according to the present embodiment, the first trap body 10 in which the first elbow 61 is connected to the connecting pipe 113 protruding in the C1 direction orthogonal to the proximity direction D1 is orthogonal to the first drain trap body 10 in the proximity direction D2. Since the drain trap body 20 to which the second elbow 62 is connected is connected to the connecting portion 71 protruding in the C2 direction from the elbow socket 70 attached to the protruding side end surface of the connecting body 213 protruding in the C2 direction, the first elbow 61 It is possible to secure a separation distance longer than the length required for connecting with the flexible hose 30 between the second connecting port 61b of the above and the second connecting port 62b of the second elbow 62. Therefore, even if the mounting positions of the first drain trap body 10 and the second drain trap body 20 are displaced by α in the C1 and C2 directions from the ideal arrangement, the first elbow 61 and the second elbow are used by using the flexible hose 30. 62 can be connected without difficulty. If the mounting position of the first elbow 61 in the first drain trap body 10 and the mounting position of the second elbow 62 in the second drain trap body 20 are separated from each other, the second connecting port 61b of the first elbow 61 and the second elbow 61 are separated from each other. The separation distance of the second elbow 62 from the second connection port 62b can be increased, but on the other hand, the connection range by the flexible hose 30 becomes long, so the separation distance should be set to a necessary and sufficient distance according to the amount of deviation that can be absorbed. As described above, it is desirable to set the mounting position of the first elbow 61 in the first drain trap body 10 and the mounting position of the second elbow 62 in the second drain trap body 20.

FIG. 3C shows C1 and C2 from the ideal mounting positions of the first drain trap body 10 and the second drain trap body 20 when the drain trap device 1 is attached to the bathtub side pan 41 and the washing place side pan 42. It shows the case where the deviation occurs by -α in the direction. Even in this case, in order to connect the virtual connecting pipe 101 and the virtual connecting pipe 201 using the flexible hose 30 as in the conventional drain trap device, the flexibility of the flexible hose 30 causes a deviation in the C1 and C2 directions. -It is necessary that the virtual connecting pipe 101 and the virtual connecting pipe 201 are separated to the extent that α can be absorbed. However, since the virtual connecting pipe 101 and the virtual connecting pipe 201 project in the proximity directions D1 and D2, respectively, it is not possible to secure a separation distance longer than the length required for connecting with the flexible hose 30, and the flexible hose. It is difficult to reasonably connect the virtual connecting pipe 101 and the virtual connecting pipe 201 using the 30.

On the other hand, in the drain trap device 1 according to the present embodiment, the first trap body 10 in which the first elbow 61 is connected to the connecting pipe 113 protruding in the C1 direction orthogonal to the proximity direction D1 is orthogonal to the first drain trap body 10 in the proximity direction D2. Since the drain trap body 20 to which the second elbow 62 is connected is connected to the connecting portion 71 protruding in the C2 direction from the elbow socket 70 attached to the protruding side end surface of the connecting body 213 protruding in the C2 direction, the first elbow 61 It is possible to secure a separation distance longer than the length required for connecting with the flexible hose 30 between the second connecting port 61b of the above and the second connecting port 62b of the second elbow 62. Therefore, even if the mounting positions of the first drain trap body 10 and the second drain trap body 20 are displaced by −α in the C1 and C2 directions from the ideal arrangement, the flexible hose 30 is used to make the first elbow 61 and the second. The elbow 62 can be connected without difficulty.

As described above, in the drain trap device 1 according to the present embodiment, the water passage hole 111b of the water storage vacant portion 111a of the first drain trap body 10 and the water passage hole 211b of the water storage vacant portion 211a of the second drain trap body 20 Is provided in a direction different from the proximity directions D1 and D2 (the water passage hole 111b of the first drain trap body 10 is in the connection direction C1 and the water passage hole 211b of the second drain trap body 20 is in the connection direction C2). The drain trap body 10 is provided with a first elbow 61 (a pipe joint in which the second connecting port 61b opens in the D1 direction while projecting from the first connecting port 61a in the C1 direction and bending) that communicates with the water passage hole 111b. The second drain trap body 20 is provided with a second elbow 62 (a pipe joint that protrudes from the first connecting port 62a in the C2 direction and bends in the D2 direction, and the second connecting port 62b opens) that is communicated with the water passage hole 211b. By providing it, the arrangement can be adjusted so that the second connecting port 61b of the first elbow 61 and the second connecting port 62b of the second elbow 62 face each other.

In addition, in the drain trap device 1 according to the present embodiment, the second connecting port 61b of the first elbow 61 provided in the first drain trap body 10 and the second elbow 62 provided in the second drain trap body 20. Since a separation distance longer than the length required for connecting with the flexible hose 30 can be secured between the second connecting port 62b, the mounting positions of the first drain trap body 10 and the second drain trap body 20 are ideal. It is possible to connect the first elbow 61 and the second elbow 62 reasonably by using the flexible hose 30 even if the arrangement is deviated by about ± α in the C1 and C2 directions.

Since the first drain trap body 10 is provided with one water passage hole 111b in the water storage portion 111, which is a bowl-shaped bottomed hemisphere, and the connecting pipe 113 is projected outward, the connecting pipe 113 is formed. The 113 can be attached to the bathtub side pan 41 without any problem in any direction. Therefore, in the first drain trap body 10, the connecting pipe 113 is arranged so as to protrude in the C1 direction orthogonal to the proximity direction D1, so that the water passage hole 111b is provided in the C1 direction orthogonal to the proximity direction D1. become.

Further, since the second drain trap body 20 must arrange the water distribution pipe connecting portion 214 for connecting to the water distribution pipe in a predetermined direction, the arrangement is changed so that the elbow socket 70 faces in an arbitrary direction. Can't. Therefore, in the second drain trap body 20, it is necessary to arrange the facing surface 211-1 of the water storage unit 211 having a four-side wall structure so as to face the D2 direction, and to provide the water passage hole 211b in a direction different from the D2 direction. There is. If the side portion of the water storage portion 211 of the second drain trap body 20 has a curved shape or is composed of five or more side wall surfaces, the direction in which the water passage hole 211b is provided can be selected from various directions. However, in the water storage portion 211 having a four-side wall structure, the water passage hole 211b can be provided in the first side surface 211-2 or the second side surface 211-3 facing the C2 direction orthogonal to the D2 direction. For example, when the direction of L90 ° with respect to the proximity direction D2 is the connecting direction C2, a second drain trap body provided with a connecting body having a water passage hole 211b on the second side surface 211-3 side is used. The first elbow 61 or the second elbow 62 may be attached via the elbow socket 70.

Further, since the drainage tapered surface 211-4 of the water storage portion 211 is a wall portion facing in the anti-D2 direction (a wall portion not facing in the D2 direction), a water passage hole 211b may be provided in the drainage tapered surface 211-4. Not impossible. However, when the water passage hole 211b is provided in the drainage tapered surface 211-4, the first elbow 61 provided in the first drain trap body 10 is provided with a pipe joint that bends or curves from the anti-D2 direction to the D2 direction. Since it is necessary to arrange the two connecting holes 61b so as to face each other, the connecting path between the first drain trap body 10 and the second drain trap body 20 becomes unnecessarily long, which is inefficient and long. It becomes a water flow path and stability is also impaired. Therefore, it is desirable to exclude the drainage tapered surface 211-4 of the water storage unit 211 from the target for providing the water passage hole 211b.

In the drain trap device 1 according to the above-described embodiment, the first elbow 61 is provided on the first drain trap body 10 side and the second elbow 62 is provided on the second drain trap body 20 side. The second connecting hole 61b and the second connecting hole 62b of the second elbow could be arranged so as to face each other, but the first and second drain trap bodies 10, 20 or the first and second were used. Depending on the size and shape of the elbows 61 and 62, the second connecting hole 61b of the first elbow 61 and the second connecting hole 62b of the second elbow may not always be arranged so as to face each other. In preparation for such a case, a large number of elbows having different protrusion amounts from the first connecting hole to the opening position of the second connecting hole are prepared in advance, and the elbow can be connected reasonably by using the flexible hose 30. May be selected and used.

Further, in the curved first elbow 61, the amount of protrusion from the first connecting hole 61a to the opening position of the second connecting hole 61b is from the first connecting hole 62a to the second connecting hole 62b in the bent second elbow 62. Since it is larger than the amount of protrusion to the opening position of, the difference in the amount of protrusion is used to adjust so that the elbow on the first drain trap body 10 side and the elbow on the second drain trap body 20 side can be connected reasonably. It is also possible.

For example, as in the drain trap device 1'of the first modification shown in FIG. 4, the mounting positions of the first drain trap body 10 and the second drain trap body 20 are more than α in the C1 and C2 directions from the ideal arrangement. When only a large β1 is deviated, a bent second elbow 62 is attached to the first drain trap body 10 to reduce the amount of protrusion from the first connecting hole 62a to the opening position of the second connecting hole 62b. First, a curved first elbow 61 is attached to the second drain trap body 20 to increase the amount of protrusion from the first connecting hole 61a to the opening position of the second connecting hole 61b. In this way, the deviation between the second connecting hole 62b of the second elbow 62 and the second connecting hole 61b of the first elbow 61 can be suppressed to a minute range, and the separation distance longer than the length required for connecting with the flexible hose 30. The flexible hose 30 can be used to reasonably connect the second connecting hole 62b of the second elbow 62 and the second connecting hole 61b of the first elbow 61.

Further, in the above-mentioned drain trap devices 1, 1', the first drain trap body 10 and the second drain trap body 20 are provided with the first elbow 61 or the second elbow 62, but the first drain is not always the case. The elbow is not limited to the one provided in both the trap body 10 and the second drainage trap body 20. At least, the first drain trap body 10 can be used without adjusting the direction of the second connecting hole by providing an elbow because the protruding direction of the connecting pipe 113 can be set to an arbitrary direction.

For example, as in the drain trap device 1 ″ of the second modification shown in FIG. 5, the mounting positions of the first drain trap body 10 and the second drain trap body 20 are located more than β1 in the C1 and C2 directions from the ideal arrangement. When only a large β2 is displaced, a bent second elbow 62 is attached to the second drain trap body 20 to reduce the amount of protrusion from the first connecting hole 62a to the opening position of the second connecting hole 62b. 1 The elbow is not attached to the drain trap body 10, and the connecting pipe 113 is arranged in the direction L30 ° with respect to the proximity direction D1 (the connecting direction C1 toward the second connecting hole 62b of the second elbow 62). , The deviation between the open end of the connecting pipe 113 in the first drain trap body 10 and the second connecting hole 62b of the second elbow 62 is suppressed to a minute range, and the separation distance is longer than the length required for connecting with the flexible hose 30. The flexible hose 30 can be used to reasonably connect the connecting pipe 113 of the first drain trap body 10 and the second connecting hole 62b of the second elbow 62.

The above-mentioned drain trap devices 1, 1 ′, 1 ″ all correct the deviations generated in the directions orthogonal to the proximity directions D1 and D2 of the first drain trap body 10 and the second drain trap body 20, and the first one. A pipe joint such as a first elbow 61 or a second elbow 62 is used as a drainage communication means for reasonably connecting the water storage vacant portion 111a in the drain trap body 10 and the water storage vacant portion 211a in the second drain trap body 20. However, when the drain trap device 1, 1', 1 "is attached to the bath side pan 71 and the washing place side pan 42, adjustment may be necessary because the installation heights are different. Spacer packing 50 can be used for such height adjustment.

As shown in FIG. 6, the spacer packing 50 made of an elastic material has an annular spacer portion 51 having a required thickness, a hold portion 52 protruding downward from the outer edge portion of the spacer portion 51, and a spacer portion 51. An annular sealing projection 53 is provided on the upper surface 51a and the lower surface 51b, respectively (for example, two rings on the upper surface 51a and two rings on the lower surface 51b). The lower surface 51b of the spacer portion 51 abuts on the annular contact surface 212b of the flange portion 212 on the main body side, and the upper surface 51b is around the lower surface side of the drainage through hole 42a of the washing place side pan 42 (rubber when using the rubber packing 23). It hits the lower surface of the packing 23). That is, when the upper surface 51a and the lower surface 51b of the spacer portion 51 are sandwiched between the lower surface of the washing place side pan 42 and the annular contact surface 212b of the main body side flange portion 212 and receive an appropriate pressing force, each sealing projection 53 is crushed. Therefore, a sealing structure can be formed between the lower surface of the washing place side pan 42 and the annular contact surface 212b of the main body side flange portion 212. Further, the inner peripheral surface 52a of the hold portion 52 is an annular wall body having an inner diameter that fits into the outer peripheral surface 212a of the flange portion 212 on the main body side.

Generally, since the bottom surface of the tub is deeper than the washing place, the height at which the drainage through hole 42a of the washing place side pan 42 is provided is higher than the height at which the drainage through hole 41a of the tub side pan 41 is provided. However, as shown in FIG. 7A, when the position of the drainage through hole 42a in the washing place side pan 42 is higher than the ideal mounting position of the second drainage trap body 20, the inside of the water storage vacant portion 211a The reference water level WL of the sealed water collected in the water is increased, and in conjunction with this, the reference water level WL of the sealed water collected in the water storage vacant portion 111a of the first drain trap body 10 is increased. Therefore, if the reference water level WL of the sealed water collected in the water storage vacant portion 111a of the first drain trap body 10 exceeds the permissible range and rises to the vicinity of the opening surface of the drain port, construction failure will occur.

Therefore, as shown in FIG. 7B, when the spacer packing 50 is used and the trap body 21 of the second drain trap body 20 is adjusted so as to have an ideal mounting position, it accumulates in the water storage vacant portion 211a. The reference water level WL of the sealed water becomes the ideal height, and in conjunction with this, the reference water level WL of the sealed water collected in the water storage vacant portion 111a of the first drain trap body 10 is also adjusted to the ideal height. It becomes. In this way, if the spacer packing 50 is used, even if the position of the drainage through hole 42a in the washing place side pan 42 is higher than the ideal mounting position of the second drainage trap body 20, the second drainage trap body 20 The trap body 21 can be adjusted to the ideal mounting position. Since the height adjusted depending on the situation varies, a plurality of types of spacer packings 50 having different thicknesses (heights) of the spacer portions 51 are prepared in advance, and the spacer portions 51 having a suitable thickness are prepared in advance. The spacer packing 50 provided with the above may be selected and used.

In addition, in order to eliminate the height abnormality of the drainage through hole 42a in the washing place side pan 42, a spacer packing 50 provided with an appropriate spacer portion 51 may be used. For example, FIG. 8A shows. As shown, when the spacer packing 50'without the hold portion 52 is used, the lower surface 51b of the spacer portion 51 is properly placed on the annular contact surface 212b of the flange portion 212 on the main body side, and the proper position of the pan 42 on the washing place side is maintained. It is difficult to bring it to, and it will be misaligned or fall, resulting in poor workability.

On the other hand, as shown in FIG. 8B, when the spacer packing 50 provided with the hold portion 52 is used, the hold portion 52 is fitted on the upper portion of the outer peripheral surface 212a of the flange portion 212 on the main body side, so that the spacer packing 50 is fitted. Does not shift or fall, and workability can be improved. The hold portion 52 does not necessarily have to be annular because it is sufficient to prevent the spacer packing 50 from coming off from the proper position of the flange portion 212 on the main body side. Is also good.
