Description

Drain Traps {DRAIN WATER TRAP}

The present invention relates to a drain trap used for a wash basin of a toilet, and more particularly, to facilitate drainage of drainage, backflow prevention and cleaning of odors, prevention of loss of parts in advance, and easy desorption with a simple structure. An improved drain trap.

The drain trap 110 for the conventional washbasin 100 is S type and P type. As shown in Fig. 8, either type is made of an opaque material, and when installed, it is intended to be fastened by using the nut 114 at the wash basin 100 or at two places inside the sink.

This wash basin drain trap 110 has a large amount of water to prevent odor backflow to be accumulated in the curved pipe 112, because the water pressure is considerable, the discharge speed of the wash water is slow. These drawbacks are particularly inconvenient to use due to the long waiting time for the next person to use in public washrooms or toilets used by many people.

In addition, in the conventional drain trap structure 110, the filtering function for filtering foreign matter such as hair is insufficient. As such, the filtration function is inadequate so that sometimes the trap is clogged by foreign matters, and the drainage function is reduced or lost.

In addition, the conventional drainage trap 110 for the washbasin was not able to examine the internal situation without disassembling it, and it was difficult to grasp the appropriate time of internal cleaning. It was inconvenient.

In addition, the conventional drain trap 110 is very difficult to perform the piping work due to the structure of the S-type and P-type when the lower end of the wash basin drain trap 110 and the position of the drain does not match when installing the sink before the washbasin installation. It was difficult to have a problem in construction that can not achieve accurate piping work.

In order to solve such a conventional problem, the present inventors filed a 'wash basin trap' as Utility Model Registration No. 96-12 of 1996.1.3, which was registered as Utility Model Registration No. 133501, which is the most conventional type. The problem is solved.

However, since Utility Model Registration No. 133501 is a separate type of filter from the lower body, when disassembling and cleaning such a wash basin trap, the filter is often lost and cannot be installed in the wash basin trap. In such a case, since the function to prevent the backflow of odors in the wash basin trap is lost, the loss of parts of the strainer significantly reduces the function of the wash basin trap.

The present invention is to solve the conventional problems as described above, the purpose is to achieve a more rapid drainage of discharged water, to prevent the loss of parts in advance to ensure the prevention of backflow of odors, and to reduce the number of parts It is easy, and at the time of installation of the drain before the washbasin, the lower part of the drain trap and exactly the position of the sewer to ensure a smooth piping work, and to provide an improved drain trap for easy mounting and removal.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

2 to 4, the drain trap 1 according to the present invention has an upper body 10 having an upper end connected to a drain pipe or a drain valve 5, and in turn on the upper body 10. Has an intermediate body 20 and the lower body 40 to be connected.

The upper body 10 is directly connected to the lower end of the drain pipe, or the drain valve 5 of the wash basin 100 by a screw type, and forms a hollow common passage 12 therein, the induction pipe 14 is formed at the bottom Has a structure.

In addition, the upper body 10 forms a female screw portion 16 at the lower end, and the lower end 14a of the guide tube 14 extends somewhat lower than the outer peripheral lower end 10a of the upper body 10. .

Intermediate body 20 is coupled to the lower end of the upper body 10, the filter 22 is formed integrally formed to surround the outside of the induction pipe 14, the inner body of the upper body 10 From the hollow flow path 12, it has a structure which forms the flow path 24 and 26 which runs between the said induction pipe 14 and the filter 22, and between the filter 22 and the inner wall.

The intermediate body 20 forms a male screw portion 28a for screwing to the upper body 10 on the upper outer circumferential surface, and a male screw portion 28b for coupling with the lower body 40 to be described later on the lower outer circumferential surface. ). And, the intermediate body 20 is formed integrally with the filter 22 in the inner bar, the filter 22 has a hollow hollow cylindrical structure of the lower end, the outer surface of the plurality of connecting ribs 30 It is formed integrally with the inner wall of the intermediate body (20) through.

The filter 22 has a diameter larger than the guide tube 14 of the upper body 10, smaller than the inner diameter of the intermediate body 20, as shown in FIG. 4B), and the intermediate body 20. When the coupling with the upper body 10 is configured to surround the filter 22 is wrapped around the lower end of the induction pipe (14). That is, as shown in Figure 4a) the lower end 14a of the guide tube 14 extends into the filter 22, and accordingly hollow formed in the guide tube 14 of the upper body 10 The flow paths 24 and 26 are formed from the mold flow path 12 between the guide tube 14 and the filter 22 and between the filter 22 and the inner wall of the intermediate body 20.

In addition, since the lower body 14a of the induction pipe 14 extends inwardly of the strainer 22 when the intermediate body 20 is coupled to the upper body 10, water is filtered into the strainer 22. If soaked, the induction pipe 14 is locked into the water contained in the filter 22, which is to exhibit a blocking function to prevent the odor of the sewage pipe to flow back through the induction pipe (14).

In addition, since the filter body 22 is formed integrally with the intermediate body 20 as described above, the intermediate body 20 does not lose the component when disassembling and assembling the component.

On the other hand, the upper body is coupled to the intermediate body 20 and the lower body 40 is connected to the flexible pipe 60 at the bottom forms a hollow sharing path 42 in communication with the flow path of the intermediate body 20 and have.

The lower body 40 is screwed to the male screw portion 28b formed on the lower outer circumferential surface of the intermediate body 20 by forming a female screw portion 45 on the upper inner circumferential surface. And, as shown in Figure 4a) for coupling with the flexible pipe 60, the lower end is formed with an annular groove 47, the upper end of the flexible pipe 60 to the inside of the annular groove 47 After the fitting, it is fixed by the bolt 50 or the like penetrating the side of the lower body.

When the drain trap 1 of the present invention configured as described above is mounted to the drain valve 5 or the drain pipe, the water to be drained through the induction pipe 14 of the upper body 10, the central flow passage 12 through the induction pipe It flows through the flow path 24 between 14 and the filter 22, and the flow path 26 which runs between the filter 22 and the inner wall, and is drained to the flexible pipe 60 side.

In this case, the water dropped through the flow passage 12 of the upper body 10 is once buried in the bottom of the filter 22, and then the flow path between the guide tube 14 and the filter 22 by the reaction force ( 24 and through the flow path 26 between the filter 22 and the inner wall. As such, foreign matters such as hair are filtered through the filter 22 in the process of draining water, and the user can prevent the loss of the filter 22 even when the user disassembles and cleans the inside.

In addition, the drain trap (1) of the present invention has a straight structure to occupy much less space of the washbasin 100, making it easy to secure the space, and the installation and dismantling work by all three parts easy.

In addition, since it does not receive a large head pressure as in the S-shape and the P-shape as in the prior art, the water exiting the trap is quickly discharged, and the filter 22 is operated by the action of the induction pipe 14 and the filter 22. When the water is contained in the lower end of the induction pipe 14 is locked, it is possible to prevent the odor flowing back to the sewer pipe is very convenient in use.

In addition, since it can replace all of the conventional S-shaped structure or P-type structure, it is possible to use universally. In addition, even when the position of the lower end of the basin drain trap and the sewer does not coincide with each other at the time of installation of the sewer before the installation of the sink, the construction efficiency can be improved by making the pipe work smoothly.

Meanwhile, in the above, the structure in which the flexible pipe 60 is connected to the lower body 40 through the bolt 50 has been described, but unlike the above, the flexible pipe 60 is formed by using the O-ring 55 and the key 70. ) May be combined.

5 to 7, the drain trap 1 'does not form an annular groove 47 in the lower body 40, but instead forms a male screw portion 57 on the lower outer peripheral surface thereof. And a tightening cap 63 for screwing into the male screw portion 57, and an o-ring 55 and an annular key 70 are positioned inside the tightening cap 63, wherein the ring The mold key 70 forms a cutout 70a at one side to be fitted into the recess 60a of the flexible pipe 60, as shown in FIG.

That is, such a deformed structure is when the tightening cap 63 is mounted on the lower body 40 so that the flexible pipe 60 is connected, as shown in FIG. 7, the lower edge and the key 70 of the lower body 40. O-ring (55) is pressed between the upper surface of the () to act as a sealing, the key 70 is inserted into the recessed portion (60a) of the flexible pipe 60, and is caught on the inner peripheral surface of the tightening cap (63) It is supported by the support is not expanded to the outside, so that the convex portion 60b of the flexible pipe 60 does not fall out by the key 70 to form the connection of the flexible pipe 60.

On the other hand, the configuration and effect of the other parts except the deformation structure between the lower body 40 and the flexible pipe 60 is the same as the contents described in relation to the embodiment of FIG. Detailed description will be omitted.

On the other hand, in the induction pipe 14 has been presented a structure extending to the lower side longer than the lower end of the outer peripheral surface of the upper body 10, the subject innovation is not limited to this, the induction pipe 14 is the upper body 10 It is shorter than the lower edge of the, instead of the upper edge of the filter 22 is relatively high to prevent the bad smell backflow.

Even in this case, the filter 22 surrounds the outside of the guide tube 14, and when water is contained inside the filter 22, the guide tube 14 must be submerged in water to prevent bad smell flow. Of course it can be done.

As described above, according to the present invention, it achieves a faster drainage of the discharge water than the conventional S-shaped and P-type structure, and prevents the loss of parts such as filter 22 in advance to ensure the prevention of backflow of odor , It is made of a simple structure is easy to clean, improved practical effect is obtained so that the drain pipe or drain valve (5), easy to enter and detach. In addition, even when the position of the bottom of the basin drain trap and the sewer does not coincide with the sewage prior to the installation of the sink, the flexible pipe can be used to precisely match them, thereby achieving a smooth piping work.
