Description

Drain Traps {DRAIN TRAPS}

The present invention relates to a drain trap, and more particularly, to a drain trap that can simplify the assembly work and reduce the manufacturing cost, as well as improve the versatility.

In general, drain traps are installed in sewage pipes such as washbasins and toilets, and are classified into P traps, S traps, U traps, and belt traps according to their shape and function. Such a drain trap can prevent backflow of odor by accommodating a predetermined amount of wastewater when discharging various household wastewater into sewage pipes.

However, floors such as bathrooms, verandas, laundry rooms, etc., are limited in use because they do not have enough space to install such drain traps.

Accordingly, the collecting member for preventing odors is installed at the entrance of the sewer pipe on the floor of the bathroom, the veranda, the laundry room, and the like. The collecting member is provided with an accommodating portion for receiving sewage along the circumference of the sewage pipe, and the sewage flowing into the sewage pipe is temporarily stored in the accommodating portion and then drained along the sewage pipe.

However, in the case of such a collecting member, as the sewage passes through the receiving part, not only the rate of drainage of the sewage is reduced, but also the odor flows back because the sewage stored in the accommodating part does not completely block the sewage pipe. If it is, the sewage stored in the receiving unit will rot, causing odor.

In addition, since the diameter of the sewage pipe is different according to the use and location, the size of the collecting member should also be manufactured to match the diameter of the sewage pipe. That is, there is a disadvantage that the manufacturing cost increases as the collection member of various sizes are manufactured.

Accordingly, by developing a drain trap formed in a structure that is simple enough to be installed on the floor of a bathroom, a veranda, a laundry room, etc., not only can the assembly work be simplified and the manufacturing cost can be reduced, but the general purpose of the drain trap can be achieved. You will have to seek.

It is achieved by a drain trap characterized in that it comprises a pipe.

The trap pipe part may include an outer tube disposed adjacent to an inner wall of the sewage pipe, an inner tube disposed in a concentric manner inside the outer tube, and a connecting portion connecting the inner tube and the outer tube.

The connection portion may be recessed from the upper surface of the outer tube and the inner tube to form a groove.

On the outer circumferential surface of the exterior, a locking projection protruding along the circumferential direction of the exterior may be formed.

The discharge pipe portion is formed by a space between the inner tube and the outer space of the trap pipe portion, and secures the discharge pipe portion to the trap pipe portion, an extension portion extending downward from the trap tube portion with a predetermined inclination angle, and extending from the extension portion and having a cut line formed therein. It may include a discharge.

A plurality of incisions are formed in the discharge part at predetermined intervals along the circumferential direction of the discharge pipe part, and the ends of each incision line may meet at one point.

The extension part may be formed such that the area corresponding to the incision line becomes thicker from the adjacent area of the coupling part toward the discharge part.

The discharge portion may be formed to become thinner from the region adjacent to the extension to the end of the incision line.

The trap pipe portion may be formed of a plastic resin.

The discharge pipe portion may be formed of at least one of rubber and silicone having elasticity.

1 is a perspective view of a drain trap according to the present invention, FIG. 2 is an exploded perspective view of the drain trap of FIG. 1, FIG. 3 is a top view of the drain trap of FIG. 1, and FIG. 4 is a cross-sectional view of the drain trap of FIG. 1.

The drain trap 1 is mounted in a sewage pipe, and includes a trap pipe part 10 formed in a tubular shape, and a discharge pipe part 20 that is opened or closed in accordance with the discharge of sewage.

The trap pipe part 10 is mounted on the inlet side of the sewage pipe and serves to support the discharge pipe part 20, and includes an exterior 11, an inner pipe 13, and a connection part 15.

The external appearance 11 of the trap pipe part 10 is arrange | positioned adjacent to the inner wall of a sewage pipe, and is formed in tubular shape. In the upper side of the exterior 11, a locking projection 18 protruding outward is formed over the entire region along the circumferential direction of the exterior 11.

The inner tube 13 is disposed inside the outer tube 11 at predetermined intervals from the outer tube 11, and the inner tube 13 and the outer tube 11 are disposed on concentric circles. The connection part 15 which connects the exterior 11 and the inner tube 13 is formed between the exterior 11 and the inner tube 13.

A plurality of connecting portions 15 are formed at predetermined intervals along the circumferential direction of the exterior 11 and the inner tube 13, and a space 19 is formed between the connecting portions 15. In addition, the connection part 15 is formed by recessing a predetermined height from the upper surface of the outer tube 11 and the inner tube 13, and thus, the upper region between the outer tube 11 and the inner tube 13 has a groove having a circular edge shape ( 17) is formed. The number or position of the connecting portion 15 may be arbitrarily determined by the designer, and in this embodiment, the number of the connecting portions 15 is formed to correspond to the number of cut lines 35 of the trap pipe portion 10 to be described later. . And the connecting portion 15 may be formed to correspond between the incision line 35 and the incision line 35, in this embodiment is formed to correspond to each incision line 35.

The trap pipe portion 10 is formed of a plastic resin in order to retain the support force to support the discharge pipe portion 20.

The discharge pipe part 20 is formed in the shape of a funnel as a whole to collect sewage, and is made of a material having elastic force, for example, silicon, rubber, or the like. The discharge pipe portion 20 includes a coupling portion 25, extension portion 30, discharge portion 31.

The coupling portion 25 is integrally coupled with the trap tube portion 10 and is formed by the space 19 and the groove 17 between the inner tube 13 and the outer surface 11. The discharge pipe part 20 of the present embodiment is formed integrally with the trap pipe part 10, for this purpose, inserting the completed trap pipe part 10 into the injection molding machine of the discharge pipe part 20, the discharge pipe part 20 By inserting the raw material into the injection molding machine, the trap tube portion 10 and the discharge tube portion 20 are integrally molded. Accordingly, the coupling portion 25 is formed in the trap pipe portion 10, the discharge pipe portion 20 is formed integrally with the trap pipe portion (10).

The coupling portion 25 is formed by a plurality of coupling pieces 22 formed by the space 19 between the inner tube 13 and the outer tube 11, and the groove 17 on the inner tube 13 and the outer tube 11. It includes a circular border ring portion 21 is formed. Here, as the space 19 between the inner tube 13 and the exterior 11 is formed in an area corresponding to the incision line 35, the coupling piece 22 is disposed between the incision line 35 and the incision line 35. It is formed to correspond to.

The extension part 30 extends downward from the coupling part 25 with a predetermined inclination angle and serves to support the discharge part 31. The area corresponding to each cut line 35 of the extension part 30 is formed so that its thickness becomes thicker from the coupling part 25 area to the discharge part 31 area, and the width coupling part 25 becomes thicker. It becomes wider toward the discharge part 31 from (). That is, the area corresponding to each cut line 35 of the extension part 30 extends in thickness and width in a triangular shape to protrude outward of the extension part 30. Accordingly, since the extension portion 30 protrudes from a region corresponding to each incision line 35, the cross section is formed in a polygonal shape along the circumferential direction. At this time, since the thickness and width of the portion corresponding to each incision line 35 is increased, if the incision line 35 is formed of four, the extension portion 30 has a rectangular cross section, the incision line 35 is If formed in three, the extension portion 30 is triangular in cross section.

The discharge part 31 coupled to the lower part of the extension part 30 is formed in a funnel shape having the same or gentle inclination angle as the extension part 30.

The discharge part 31 is formed with a plurality of incision lines 35 at regular intervals along the circumferential direction. Each cut line 35 is formed to extend from the upper region to the lower region of the discharge portion 31, each cut line 35 is met at one point of the lower end of the discharge portion (31). Each of these incisions 35 are spaced apart from each other when the inflow of wastewater forms a discharge port through which wastewater is discharged.

The discharge part 31 is formed so that its thickness gradually becomes thinner from the upper part to the lower part, and the area | region in which each cut line 35 was formed is formed thicker than the other area | region of the discharge part 31. As shown in FIG. In addition, the area where each cut line 35 is formed is also formed such that its thickness gradually becomes thinner from the top to the bottom of the discharge part 31. As the discharge part 31 is formed in a thick region formed in each incision line 35, the region in which each incision line 35 is formed to protrude to the outside is formed in a polygonal shape as a whole. In the present embodiment, as the four incision lines 35 are formed, the discharge portion 31 is formed in a quadrangular pyramid shape, but the number of the incision lines 35 may be changed by a designer, and the incision line 35 The shape of the discharge part 31 is determined according to the number of.

On the other hand, the length of the cut line 35 may be determined by the amount of sewage, it may also be determined by the elastic force of the discharge portion (31). If the amount of sewage is large, the length of the incision line 35 may be formed relatively long in order to discharge a large amount of sewage at a time, on the contrary, if the amount of sewage is small, the length of the incision line 35 Can be formed relatively short. And when the elastic force of the discharge part 31 is large, the force to withstand the pressure of the sewage is increased, so that the length of the incision line 35 will be lengthened so that the incision line 35 can be easily opened during the inflow of sewage. .

Since the discharge portion 31 becomes thinner gradually toward the bottom, when the sewage is introduced, a difference occurs in the degree of opening of the cut line 35 according to the weight of the sewage. That is, when a small amount of sewage flows in, as shown by the solid line in FIG. 6, since the pressure applied to the discharge part 31 by the sewage is relatively small, the width at which the cut line 35 opens is small, and when a large amount of sewage flows in. 6, since the pressure applied to the discharge part 31 by the sewage is relatively large, the width of the cut line 35 is wide. Thus, the opening width of the outlet formed by the cut line 35 is determined according to the amount of sewage.

On the other hand, since the area corresponding to the incision line 35 in the extension part 30 and the discharge part 31 is thicker than other areas, the wastewater is discharged and then discharged by the elastic force of the discharge part 31. When is closed, it provides an additional elastic force to the discharge portion 31 to facilitate the closing of the discharge port.

This drain trap 1, as the trap pipe portion 10 and the discharge pipe portion 20 is integrally injection molded, to prevent the time and human waste caused by assembling a plurality of elements in the existing drain trap (1) Can be. In addition, since the drain trap 1 is made of plastic resin, rubber, silicone, or the like, when a metal wire or piece is used to close the drain trap 1, there is a problem of rusting and loss of elasticity. Can be removed.

5 is a perspective view of a state in which the drain trap according to the present invention is mounted on a sewer pipe using a mounting member, and FIG. 6 is a side cross-sectional view of the drain trap of FIG.

The mounting member 40 is used to mount the drain trap 1 on the sewage pipe, and is formed in a disc shape. The through hole 45 for the passage of the trap tube portion 10 is formed in the central region of the mounting member 40, the edge of the through hole 45 is coupled to the lower portion of the locking step 18 of the trap tube portion 10 This prevents the mounting member 40 from being separated from the drain trap 1.

On the other hand, the inlet of the sewage pipe is coupled to the collecting member 50 for collecting sewage of the bathroom or porch. The edge portion of the collecting member 50 is formed with a rectangular border for coupling with the collecting member cover, and a collecting tube coupled to the sewer pipe is formed in the central region of the collecting member 50. In addition, the collecting member 50 is formed with an inclined surface 51 formed to be inclined downward from the edge toward the collecting pipe 60, and a seating jaw 55 formed flat between the inclined surface 51 and the collecting pipe 60. .

The mounting member 40 is seated on the seating jaw 55, and the seating jaw 55 and the mounting member 40 are coupled to each other by an adhesive. Accordingly, the width of the mounting member 40 should be formed substantially the same as the width of the seating jaw (55). By the way, the mounting jaw 55 of the collection pipe 60 is formed in the width | variety different according to the installation place and the objective. Therefore, if the diameter of the mounting member 40 is formed too narrow, it may be too small than the mounting jaw 55 of the collecting pipe 60, the installation may be unstable. However, if the diameter of the mounting member 40 is formed too wide, the mounting member 40 extends to the inclined surface because it is too large than the seating jaw 55 of the collecting pipe 60, it is not possible to fix the drain trap (1).

In order to solve this, the mounting member 40 is made of a material having an elastic force, for example, silicon or rubber, to cut the mounting member 40 according to the width of the seating jaw (55). That is, the installer of the drain trap 1 can cut the mounting member 40, as indicated by the dotted line in Figure 5, using scissors or the like to fit the width of the seating jaw (55).

Accordingly, the drain trap 1 may be mounted on the sewer pipe using the mounting member 40 regardless of the width or shape of the seating jaw 55. The shape of the seating jaw 55 may be generally rectangular or circular in shape, and the mounting member 40 according to the present invention may be drained according to the present invention regardless of the type or diameter of the seating jaw 55. Allow the trap to be mounted.

7 is a plan view according to an embodiment of the mounting member 40. Referring to FIG. 7, the mounting member 40 includes a cutting line 47 that may be cut using scissors or the like depending on the width of the seating jaw 55. The installer of the drain trap 1 along the cutting line 47 can be easily cut using scissors or the like.

As described above, by forming the mounting member 40 made of an elastic material to be adjusted according to the diameter of the collecting pipe 60, according to the diameter of the collecting pipe 60, the mounting member 40 of various sizes separately There is no need to make. Therefore, not only the generality of the drain trap 1 can be improved, but also it does not require an injection molding machine for manufacturing the mounting member 40 of various sizes, thereby reducing the manufacturing cost.
