Description

  Aspects of the present invention generally relate to a drain trap structure.

  For example, in a bathroom unit, drainage from a bathtub and drainage from a washing floor are once collected in a drain trap, and are discharged to, for example, a sewer pipe through a drain pipe connected to a drain port of the drain trap. The arrangement direction of the drain pipe with respect to the main body of the drain trap varies depending on the structure of the site such as a house where the unit bath is provided.

  For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2000-179021) and Patent Document 2 (2001-98604), a bathtub drain pipe is connected to one of the side surfaces of the drain trap body, and drainage is performed to the other side surface. A structure with a mouth is disclosed. In this case, drainage from the bathtub flows into the main body from the side surface of the drain trap body through the bathtub drain pipe, and drainage overflowing from the sealed water in the main body passes through the drain pipe connected to the drain outlet. It is discharged into sewage. In this structure, when various drain traps with different installation angles of bathtub drain pipes and drain outlets are produced in order to cope with different arrangement directions of drain pipes, the number of drain traps increases and the cost increases. . Further, for example, when a plurality of drain outlets having different installation angles are provided, the strength and the like deteriorate. On the other hand, if the installation angle of the bathtub drain pipe and the drain outlet is one type, the drain pipe connected to the drain outlet has to be bent greatly according to the structure of the site, and the drainage performance deteriorates. Moreover, workability deteriorates.

  On the other hand, Patent Document 3 (Japanese Patent Laid-Open No. 8-151669) discloses a structure in which an end of a bathtub drain pipe is inserted into an upper opening of a drain trap body. In this case, the drainage from the bathtub flows through the bathtub drainage pipe and flows into the main body from the upper opening of the drain trap body, and the drainage pipe overflowed from the sealing portion in the main body is connected to the drainage outlet. To be discharged into sewage. In the case of this structure, since the bathtub drain pipe is inserted at an arbitrary angle at the upper part of the main body of the drain trap, the arrangement direction of the drain pipe can be coped with. However, since it is a structure which inserts the edge part of a bathtub drain pipe in the opening of the upper part of a drain trap main body, there exists a problem that the straddle height of a bathtub becomes high.

In this way, the drain trap from which the drainage from the bathtub flows does not affect the direction of the drainage pipe, which is different depending on the site, while keeping the bathtub strut height below a certain level. There is a need for a drain trap structure that does not increase the number of drain outlets and that has good drainage and workability.

(First embodiment)
As shown in FIG. 1, the drain trap structure 101 according to the first embodiment of the present invention is provided on the waterproof floor 11 of the washing place 10, and the drain trap body 20 provided with the opening 21 on the upper part, A bathtub drainage pipe 30 that guides the bathtub water 61 in the bathtub 60 to the drain trap body 20, and the bathtub drainage pipe 30 can temporarily store the bathtub water 61 discharged from the bathtub 60. A bathtub drainage introduction part 32 which communicates with the part 31 and the bathtub drainage storage part 31 and is arranged above the bottom surface 31a of the bathtub drainage storage part 31 and introduces the bathtub water 61 from the bathtub drainage storage part 31; It has a bathtub drainage lead-out part 33 that communicates with the introduction part 32 and leads the bathtub water 61 flowing out of the bathtub drainage introduction part 32 from the opening 21 of the drain trap body 20 into the drain trap body 20.

The bathtub drainage lead-out part 33 is inserted into the inside of the sealing part 22 provided inside the drain trap body 20 from above the sealing part 22.
A drain port 40 is provided on the side surface of the drain trap body 20, and the drain port 40 communicates with the drain pipe 50.

  With this structure, the bathtub water 61 in the bathtub 60 is discharged from the bathtub drain port 62 to the bathtub drainage storage part 31, passes through the bathtub drainage introduction part 32, passes through the bathtub drainage lead-out part 33, and then enters the sealed part 22. The drainage that has been introduced and overflowed from the sealed water part 22 is discharged to, for example, a sewer pipe through a drain pipe 50 connected to the drain port 40.

  And since the bathtub drainage | leading-out part 33 is inserted inside the sealing part 22 from the upper direction of the sealing part 22, the angle of the bathtub drainage pipe line 30 and the drainage trap main body 20 can be set arbitrarily.

  In other words, in the drain trap structure 101 according to the present embodiment, the bathtub drain pipe 30 and the drain trap body 20 are not firmly coupled to each other, but the bathtub drain lead that is one end of the bathtub drain pipe 30 is provided. The portion 33 is inserted into the sealing portion 22 of the drain trap body 20, and the outer surface of the bathtub drainage outlet portion 33 and the inner surface of the sealing portion 22 are separated from each other. Thereby, the angle of the bathtub drain pipe 30 and the drain trap main body 20 can be set arbitrarily. As a result, the angle between the opening axis of the drain port 40 provided on the side surface of the drain trap body 20 and the extending direction axis of the bathtub drain pipe 30 can be arbitrarily set.

That is, as illustrated in FIG. 3A, the extending direction axis 30 x of the bathtub drain pipe 30 and the opening axis 40 x of the drain port 40 can be set in parallel.
Moreover, as represented to FIG.3 (b), (c), the extension direction axis | shaft 30x of the bathtub drainage pipe line 30 and the opening axis | shaft 40x of the drain outlet 40 can be set to arbitrary angles.

  Furthermore, as shown in FIG. 1, in the drain trap structure 101 according to the present embodiment, the bottom surface 31 a of the bathtub drain storage part 31 of the bathtub drain pipe 30 is lower than the bottom surface 32 a of the bathtub drain introduction part 32. Has been placed. Thereby, the bathtub drainage 61d drained from the bathtub 60 passes through the inside of the bathtub drainage storage part 31, and the bathtub drainage 61d of the part where the water surface rises in the bathtub drainage storage part 31 from the bottom surface 32a of the bathtub drainage introduction part 32. Then, it flows out into the drain trap body 20 through the bathtub drain introduction part 32. Thereby, the vertical distance between the inner bottom surface 60a of the bathtub 60 and the drain trap structure 101, that is, the height of the inner bottom surface 60a of the bathtub 60 from the drain trap structure 101 can be reduced.

  For example, in the case where the bathtub drainage storage section 31 is not provided in the bathtub drainage pipeline 30, in order for the bathtub water 61 in the bathtub 60 to flow out to the drain trap structure, the inner bottom surface 60a of the bathtub 60 is set more than the drain trap structure. It is necessary to set the position higher than a certain level. For example, it is necessary to install the inner bottom surface 60 a of the bathtub 60 above the upper surface of the pipe that guides the bathtub drainage 61 d to the upper surface of the sealing portion 22 of the drain trap body 20. For this reason, in such a structure, the installation position of the bathtub 60 becomes high and, as a result, the bathtub straddle height becomes higher than a desirable height.

  On the other hand, as already explained, in the drainage trap structure 101 according to the present embodiment, the bathtub drainage storage section 31 is provided in the bathtub drainage pipeline 30, so the height of the inner bottom surface 60a of the bathtub 60 is The drain trap structure 101 can be approached. For this reason, the bad influence on bathtub straddle height can be eliminated substantially.

  Thus, according to the drain trap structure 101 which concerns on this embodiment, the drain trap structure which can adapt to the arrangement | positioning direction of a different drain pipe can be provided, suppressing the bathtub span height low.

  Furthermore, as shown in FIG. 1, in the drain trap structure 101, the bottom surface 32 a of the bathtub drainage introduction part 32 is disposed below the inner bottom surface 60 a of the bathtub 60. Thereby, it is possible to prevent the water in the bathtub drain pipe 30 from flowing back into the bathtub 60.

  As shown in FIG. 1, the lower surface of the bathtub drainage lead-out portion 33 is disposed below the upper surface of, for example, the sealing portion 22 of the drain trap body 20, so that the bathtub drainage 61 d can be efficiently sealed. It is discharged into the water part 22. Thus, it is desirable that the lower surface of the bathtub drainage deriving portion 33 is disposed below the upper surface of the sealing portion 22 of the drain trap body 20.

(Second Embodiment)
As shown in FIGS. 4, 6, and 7 (a), the drain trap structure 102 according to the second embodiment of the present invention is provided on the waterproof floor 11 of the washing place 10, and the opening 21 is provided at the top. The provided drain trap body 20 and the bathtub drain pipe 30 that guides the bathtub water 61 in the bathtub 60 to the drain trap body 20, and the bathtub drain pipe 30 receives the bathtub water 61 discharged from the bathtub 60. The bathtub drainage storage part 31 that can be temporarily stored and the bathtub drainage storage part 31 communicate with each other and are disposed above the bottom surface 31 a of the bathtub drainage storage part 31, and the bathtub water 61 is introduced from the bathtub drainage storage part 31. The bathtub drainage lead-out section 32 communicates with the bathtub drainage introduction section 32 and derives the bathtub water 61 flowing out from the bathtub drainage introduction section 32 into the drain trap body 20 from the opening 21 of the drain trap body 20. Part 33; A bathtub waste water inlet portion 32 has a detachable portion 32r which allows splitting the tub drainage inlet portion 32 into a first portion and a second portion.

  That is, the drain trap structure 102 according to this embodiment is the drain trap structure 101 according to the first embodiment, in which the bathtub drainage introduction part 32 is provided with a detachable attachment / detachment part 32r.

  That is, the bathtub drainage introduction part 32 has a first part 32p on the bathtub 60 side and a second part 32q on the washing place 10 side. And between these, the attachment / detachment part 32r which connects the 2nd part 32q with respect to the 1st part 32p so that attachment or detachment is possible is provided. By removing the second portion 32q in the attaching / detaching portion 32r, the bathtub drainage introducing portion 32 can be divided into the first portion 32p and the second portion 32q to be separated.

  4, 6, and 7 (a) exemplify a state when the second portion 32 q is removed from the first portion 32 p and moved in the upper right direction on the paper surface. FIG. 5 illustrates a state in which the second portion 32q and the first portion 32p are coupled by the attaching / detaching portion 32r, and the bathtub drain pipe 30 is attached to the upper portion of the drain trap body 20. .

  Thus, in the bathtub drainage introduction part 32 of the drainage trap structure 102 according to the present embodiment, the second part 32q can be separated from the first part 32p. Easy to clean from the side. For example, even when an accessory is dropped from the bathtub drain port 62, the accessory is put into the bathtub drainage storage part 31 from the opening 32s of the first part 32p separated by the attaching / detaching part 32r. Can be taken out.

  Furthermore, since the opening 32s of the first portion 32p separated by the attaching / detaching portion 32r can serve as a work port and an inspection port during construction and maintenance management of the one-push drain plug, workability and maintenance Manageability is also improved.

  Thus, according to the drain trap structure 102 according to the present embodiment, it is possible to adapt to the arrangement direction of different drain pipes while keeping the height of the bathtub span low, easy cleaning, and high workability and maintainability. A drain trap structure can be provided.

  That is, since the bathtub drainage storage section 31 is provided in the bathtub drainage pipeline 30 in the drain trap structure 102 according to the present embodiment, the bathtub drainage 61d remains as dead water in the bathtub drainage storage section 31, and the bathtub drainage storage. It is thought that the inside of the part 31 is dirty and the frequency of cleaning inside the bathtub drainage storage part 31 is increased. At this time, as described above, by providing the bathtub drainage introduction part 32 with the detachable part 32r, the inside of the bathtub drainage storage part 31 can be easily cleaned, and a more convenient drain trap structure can be provided.

  As shown in FIGS. 4 to 6, the attaching / detaching portion 32 r can be disposed at the boundary between the washing place 10 and the bathtub 60. According to this structure, when putting a hand inside the bathtub drainage storage part 31, it is the easiest to put in, the workability such as cleaning is improved, and a more convenient drain trap structure can be provided.

  Further, as shown in FIGS. 6 and 7A, the cross section of the first portion 32p of the attaching / detaching portion 32r can have a horizontally long shape in the horizontal direction. That is, the opening of the first portion 32p exposed when the second portion 32q is detached at the attaching / detaching portion 32r can have a horizontally long shape that is long in the horizontal direction.

  Thereby, when the 2nd part 32q of the bathtub drainage introduction part 32 is removed by the attachment / detachment part 32r, the shape of the opening part 32s of the 1st part 32p becomes a horizontally long shape long in a horizontal direction. Thereby, it is easy to put a hand into this opening 32s, and workability such as cleaning is further improved.

  In addition, since the bathtub drainage introduction part 32 has a function of introducing the bathtub drainage 61d from the bathtub drainage storage part 31 toward the drainage trap main body 20, in order to drain efficiently, the cross-sectional area of the opening 32s is: It is required to be wider than a certain level. At this time, if the length in the direction perpendicular to the flow direction of the drainage of the bottom surface 32a of the bathtub drainage introduction part 32 is set as wide as possible, the efficiency is improved. Also from this viewpoint, it is more desirable that the bathtub drainage introduction portion 32 has a horizontally long shape in the horizontal direction. Also in this case, the cross-sectional shape when cut along a plane perpendicular to the extending direction of the bathtub drainage introduction portion 32 of the detachable portion 32r is a horizontally long shape in the horizontal direction.

  Further, as shown in FIG. 5, the overlap allowance 32t of the attaching / detaching portion 32r includes the bathtub drainage deriving portion 33 and the inner wall 20a of the drain trap body 20 in a state where the bathtub drain pipe 30 is attached to the drain trap body 20. And the gap 20t can be made smaller.

In the above description, the overlap allowance 32t of the detachable portion 32r is the overlap length of a plurality of portions divided in the detachable portion 32r. That is, it is the length in the direction parallel to the extending direction of the bathtub drainage introduction part 32 of the part where the first part 32p and the second part 32q overlap in the bathtub drainage introduction part 32. This overlap allowance 32t is a stroke when the second portion 32q is removed from the first portion 32p at the attaching / detaching portion 32r.
And the inner wall 20a of the drain trap main body 20 can be made into the inner wall of the sealing part 22, for example.

  The gap 20t between the bathtub drainage lead-out part 33 and the inner wall 20a of the drainage trap body 20 is within the distance between the bathtub drainage lead-out part 33 and the inner wall 20a of the drainage trap body 20; With reference to 33, the distance in the direction perpendicular to the cross section of the detachable portion 32r and extending from the first portion 32p to the second portion 32q can be used. That is, it is a gap between the bathtub drainage lead-out portion 33 and the inner wall 20a of the drain trap body 20 in the direction in which the second portion 32q is removed from the first portion 32p.

  For example, the overlap allowance 32t of the attaching / detaching portion 32r can be set smaller than the difference between the inner diameter 22d of the sealed water portion 22 and the outer diameter 33d of the bathtub drainage deriving portion 33.

  When removing the second portion 32q from the first portion 32p, it is necessary to move the second portion 32q by a distance longer than the length of the overlap allowance 32t of the attaching / detaching portion 32r. At this time, as described above, the overlap margin 32t of the detachable portion 32r is smaller than the gap 20t between the bathtub drainage deriving portion 33 and the inner wall 20a of the drain trap body 20, so The second portion 32q can be moved to separate the first portion 32p and the second portion 32q. That is, the stroke when removing the second portion 32q from the first portion 32p can be made smaller than the gap 20t. Thus, the clearance when removing the second portion 32q from the first portion 32p can be secured, and the separation at the attaching / detaching portion 32r can be easily performed.

  Thereby, the inside of the bathtub drainage storage part 31 can be easily cleaned from the washing area side, and even if an accessory is dropped from the bathtub drainage port 62, the hand can be taken out from the attachment / detachment port, and one push Since it can serve as a work port and inspection port for drain plug construction and maintenance management, workability and maintenance management are also improved.

  As shown in FIG. 7B, in another drain trap structure 103 according to the present embodiment, the bathtub drainage lead-out part 33 is configured to be separated from the bathtub drainage introduction part 32. Thus, when the bathtub drainage | leading-out part 33 is comprised so that it may isolate | separate from the bathtub drainage introduction part 32, the bathtub drainage introduction part 32 which has a horizontally long cross-sectional shape, and the bathtub drainage which has circular cross-sectional shape, for example After the lead-out part 33 is produced separately, the bathtub drainage pipe 30 can be formed by a method of combining them, and the structure is easy to make.

  In this case, when the bathtub drainage introduction part 32 and the bathtub drainage lead-out part 33 are detachably combined using, for example, screws, for example, the inside of the bathtub drainage introduction part 32 or the bathtub drainage lead-out. The inside of the portion 33 can be easily cleaned, which is more convenient.

  As shown in FIG. 8, in another drain trap structure 104 according to the present embodiment, the bathtub drain storage part 31 can be separated into an upper part 31c and a lower part 31d. With such a configuration, the bathtub drainage storage unit 31 having a complicated structure can be easily manufactured, and the drainage inlet 31b of the bathtub drainage storage unit 31 and the bathtub drainage port 62 of the bathtub 60 can be combined.
