Description

{WATER DISCHARGING TRAP FOR STINK PREVENTION}

The present invention relates to a drainage trap, and more particularly, to a malodorous drainage trap which is installed in a sewer pipe and blocks a malodorous backflow of a sewage pipe.

Generally, drainage traps are installed in sewer pipes such as sinks, wash basins, and toilets, and they are divided into P traps, S traps, and U traps depending on their shape and function. Such a drainage trap can prevent odors or insects from flowing backward by accommodating a certain amount of wastewater when discharging various kinds of domestic wastewater to a sewer pipe.

However, the bottoms of sinks, bathrooms, verandas, and laundry rooms are limited in use because they do not have enough free space to install these drainage traps.

Accordingly, a malodorous drainage trap has been developed which can be easily installed at the entrance of a sewer pipe formed on the bottom of a sink, a bathroom, a veranda, a laundry room, a washstand, and the like.

This odor-blocking drain trap is disclosed in Korean Patent No. 10-0887004.

The drain trap disclosed in Korean Patent No. 10-0887004 includes a trap tube portion mounted on an inlet of a sewer pipe and formed in a tubular shape and a slope formed in a slope formed so as to gradually narrow the width from an end portion of the trap tube portion, And an outlet pipe portion made of an elastic material and made of silicone and opened or closed by the inflow of wastewater.

However, these drainage traps are opened by the drainage pipe of silicone material being released and normally closed by the elastic force of silicon, which prevents the odor from coming up, but the sealing may not be perfect due to the limit of elastic force of silicon There is a disadvantage in that when the elasticity is loosened by a long use, odor or insects may come in between.

In addition, when a lot of water goes down through the trap, a large amount of water is irregularly falling, resulting in a "buzzing" sound, and a cavity occurs between the water and the odor through the cavity.

In order to solve such a problem, Applicant has filed and registered a drainage trap having improved drainage rate so as to not only improve the odor blocking performance but also easily drain large amounts of water (Korean Utility Model Registration No. 20-0472406) .

The applicant of the present invention has continued to research and develop a drainage trap that can improve the malodor blocking performance and prolong the service life without being satisfied.

The object of the present invention is to provide a drain trap of improved lifetime so as to maintain a good odor barrier performance without any trouble even after long use.

In order to accomplish the above object, the malodor shutoff drain trap of the present invention is inserted into an inlet of a sewer pipe and has a trap tube portion formed in a pipe shape, and is installed at a lower end of the trap tube portion. The trap is formed of an elastic material, And a discharge pipe portion having a drainage portion formed with an incision to be closed, the drainage trap preventing the reverse flow of the odor of the drainage pipe, wherein the drainage trap is formed in a plurality of radial directions from the center, And a sag preventing member for preventing sagging of the sagging is formed on a bottom surface of the sagging portion, and the sag preventing member is provided on the lower surface of the sagging portion, And is formed so as to connect the two adjacent incisions, And the bending portion is formed in the shape of a circle.

The portion connecting the plurality of incisions may be formed in a corrugated form having a plurality of mountains and a plurality of bones.

The sagging prevention member is formed of five pieces, and the sagging prevention member is formed in five pieces so as to connect the adjacent sagging members, and the sagging prevention member may have a pentagonal shape.

The sagging prevention member is formed of four pieces. The sagging prevention member is formed in four pieces so as to connect the adjacent sagging members. The sagging prevention member may have a rectangular shape.

The sagging prevention member may be formed of three pieces, and the sagging prevention member may be formed in three pieces so as to connect the adjacent sagging members, and the sag prevention member may be formed in a triangular shape.

According to the above, the malodor shielding performance is improved and the malodor shielding performance can be maintained even after long use.

That is, in the present invention, a deflection preventing member is formed on the lower surface of the discharge portion to prevent incidence of incision, and the deflection preventing member extends downward from the connecting portion of the plurality of incisions to connect the two incisions Since the bending portion is bent at a predetermined angle in the middle portion of the deflection preventing member, even when the elastic force of the discharge portion is loosened due to long use, the phenomenon caused by the cutting of the bending portion is more reliably prevented than before. It is possible to extend the service life.

The diameter of the catching protrusion 13 is formed to be larger than the diameter of the sewage pipe so that the trap pipe section 10 is inserted into the sewage pipe It is supported so that it does not fall out. In addition, the stepped portion 15 may be formed in the upper end of the trap tube portion 10.

The trap tube portion 10 is preferably formed of a plastic resin material to support the discharge tube portion 20. [

The discharge tube portion 20 is made of a material having elasticity such as silicone or rubber and is detachably attached to the lower end of the trap tube portion 10 and is opened or closed according to the water discharged through the trap tube portion 10 And includes an engagement portion 23, an extension portion 25, and a discharge portion 30 for selectively discharging water to the sewage pipe.

All the constitutions of the discharge tube portion 20 of the present invention can be integrally formed by injection molding or the like.

The engaging portion 23 is formed in the shape of a circular pipe having a diameter slightly smaller than or equal to the lower end of the trap tube portion 10. The lower end portion of the trap tube portion 10 is inserted into the engaging portion 23 and the external force is removed so that the trap tube portion 10 and the engaging portion 23 can be fixed in close contact with each other have.

The extension portion 25 is formed in a circular pipe shape and extends integrally downward from the lower end of the engaging portion 23.

The discharge portion 30 is integrally formed to extend from the lower portion of the extension portion 25 and cover the open lower portion of the extension portion 25 so that a plurality of spiral cut- do. Therefore, when the water is not introduced, the incision 33 is closed so that the odor of the sewage is prevented from rising. When the water is introduced, the incision 33 is opened, do.

In the incision improvement (33), a plurality of incision incisions (33) spread on the basis of the center (O), and water is discharged.

In the present embodiment, the number of the incisions 33 is five, but the number of incisions 33 may be variously applied, if necessary.

The discharge portion 30 may be formed in a corrugated shape with the upper portion facing the upper portion 36 connecting the plurality of cut-outs 33 and the discharge portion 30 may be formed in the lower portion from the portion where the cut- A further protruding portion 33a is further provided. As a result, the force for collecting the incisions 33 toward the center O is raised.

In the present invention, a deflection preventing member 38 protruding downward from the lower surface of the discharge portion 30 is formed.

Specifically, the deflection preventing member 38 is composed of five pieces, each of which connects the adjacent cut-outs 33 to each other, and downwardly from the portion 36 connecting the plurality of cut-outs 33 And are formed so as to connect adjacent cut-outs 33 to each other. At this time, each of the deflection preventing members 38 is formed with a bent portion 38a having a bent shape at a predetermined angle.

In the present invention, when five deflection preventing members 38 are viewed from the bottom of the discharge portion 30, the five deflection preventing members 38 show a pentagonal ring shape.

3, the deflection preventing member 38 is represented because the discharging unit 30 is made of a material having a predetermined transparency. When the discharging unit 30 is made of an opaque material, 3, the deflection preventing member 38 is not displayed.

According to the configuration of the deflection preventing member 38, the deflection of the cutout 33 can be prevented, and even if the elastic force of the cutout 30 is loosened due to long use, the cutout 33 is opened It is possible to prevent a malodor or insect from rising.

That is, each of the deflection preventing members 38 is integrally formed so as to connect the portion 36 connecting the cut-outs 33 and the sides of the cut-outs 33, and is formed into a pentagonal tube shape having a substantially predetermined height Even if the elastic force of the discharge portion 30 is loosened, it is possible to surely prevent the incision prevention member 33 from spontaneously spreading by supporting the deflection preventing member 38 that the incision 33 is opened.

Particularly, since the deflection preventing members 38 of the present invention are formed in a circular shape, the bent portions 38a are formed, so that it is possible to prevent the incision preventing members 33 from expanding further than the circular shape .

Meanwhile, the discharge section 30 of the present invention is formed such that a plurality of the incisions 33 are inclined upwards toward the center O. That is, since the center of the discharge portion 30 is shaped to rise above the outer end portion, even after the water is drained through the discharge portion 30, some water is accumulated in the discharge portion 30 so as to cover the cut- And due to the accumulated water, the odor or insect of the sewage pipe can not be raised.

In the meantime, the deflection preventing member 38 of the present invention is formed to have a regular pentagon as shown in FIG. 4. In this case, the angle of each bent portion 38a is 108 degrees, The deflection preventing member 38 does not necessarily have to be formed to have a regular pentagon and the bent portions 38b of the respective deflection preventing members 38 may be formed at an angle smaller than 108 as shown in Fig. And it is of course possible that the bent portion 38b is made larger than 108 degrees, although not shown.

In the meantime, the drain trap of the present invention may be one in which five incisions 33 are formed as described above and five members are formed so as to form a pentagon. However, in the present invention, And the number of deflection preventing members 38 may be variously configured. 6, the bending prevention member 38 is formed in four pieces so that the bending prevention members 38 are formed in the shape of "+" The bent portion 38c formed may be configured to have an angle of 90 degrees so that the sag preventing member 38 has a rectangular shape.

7, the drain trap of the present invention has four sag preventing members 38 and four sag preventing members 38, but the sag preventing members 38 do not have a rectangular shape The bent portions 38d of the deflection preventing members 38 may be formed at angles smaller than 90 degrees and the bent portions 38d may be formed at angles larger than 90 degrees .

Although not shown in the drawing, the incision preventing members 38 may be formed to have the same number as the number of the incisions 33, and in this case, Needless to say, the angle of the bent portion of the sag preventing member 38 may be variously formed.

In addition, in the present invention, the incline reduction 33 is shown to be formed in a straight line shape, but it is not limited thereto, and it is needless to say that the incline improvement 33 may be formed in a spiral shape as shown in the previously-registered patent of the present applicant.

Meanwhile, in the above-described embodiment, the portion 36 connecting the plurality of cut-outs 33 has been described as being formed in the form of a fine bone toward the top. However, as shown in FIGS. 8 and 9, The portion 36 connecting the incision improvement 33 may be formed in a corrugated form including the mountain 36b and the valley 36a. It is needless to say that the number of the valleys 36a and the mountains 36b may be variously formed in the corrugated form in which the number of the valleys 36a is one and the number of the mountains 36b is one.

As described above, according to the present invention, since the portion 36 connecting the cut-outs 33 is formed in a corrugated form together with the deflection preventing member 38, even if the elastic force of the discharge portion 30 is loosened due to long- (33) is prevented from spreading further and preventing the odor or insect of the sewer pipe from rising.
