Description

A drainage trap with odor backflow prevention function {A DRAINING TRAP}

The present invention relates to drainage traps; More particularly, the present invention relates to a drainage trap provided with a function of preventing a malodor backflow, which is installed on the floor of a bathroom (a bathroom) or a veranda to guide water out to a drain pipe while preventing odors from flowing into the drain pipe.

In general, not only common houses such as multi-family houses and apartments but also general households are connected to a collection tank to collect various kinds of sewage, and the bottom of each family's bathroom or veranda and a collection tank are connected to each other through a drain pipe (drainage pipe). In such a drain pipe, a large amount of water and dirt, such as toilet and bathtubs around the living room, together with the odor (odor) can flow backward. In order to prevent backflow of odor (odor) The drain trap is installed.

1, a conventional drain trap is provided with a drain trap body 1 which is installed directly above a drain pipe P and in which a through hole 2 is drilled at the center, (3) which is detachably installed on the bottom of the drain trap body (2) while remaining in the bottom of the drain trap body (2) and filled with water of a predetermined height at the bottom thereof, A drainage inducing tube 4 installed to be detachable while being extended and accommodated in the inner space of the drainage residual tube 3 at a lower end portion thereof and a drainage hole 4a provided to cover the upper part of the drainage trap body 1, Is provided with a perforated filter cover (5). The water is collected in the central portion of the drain trap main body 1 through the drain holes 5a of the filter cover 5 and passes through the drain guide tube 4 and is then discharged to the drain pan (See arrow direction in Fig. 1) through the drain pipe 3a. In the drainage process, dirt such as hair is firstly filtered by the filter cover 5 and is also filtered inside the drainage induction tube 4 and the drainage residual tube 3. Since the bottom of the drainage retaining cylinder 3 is filled with water of a predetermined height and the lower end of the drainage inducing cylinder 4 is always kept locked, the backflow of the odor (odor) from the drainage pipe P is prevented.

However, in such a conventional drain trap structure, as shown in FIG. 2, if the wastewater remaining in the drainage remaining tube 3 evaporates, the smell of the drain pipe P may enter the room. That is, since the drainage remaining trough 3 is in direct communication with the room, if the house is vacated for a long time and water is not disposed on the floor of the toilet, residual water at the bottom of the drainage trough 3 is evaporated, and the drainage remaining trough 3, Serves as an air passage by directly communicating with the inside of the water pipe (P). Therefore, the odor of the water pipe P may flow back into the room through the drainage remaining tub 3 and the drainage induction pipe 4 (see the arrow direction in FIG. 2) .

The present invention addresses this problem. The object of the present invention is to provide a method and apparatus capable of selectively opening and closing the drainage window of the drainage canal by the load of the drainage sewage to thereby fundamentally prevent odor and pest from flowing into the room Drainage trap ".

FIGS. 3 to 5 show the construction of the drain trap according to the present invention, and FIGS. 6 and 7 show operation states of the drain trap according to the present invention.

≪ Construction of drain trap according to the present invention >

As shown in FIGS. 3 and 4, the drain trap according to the present invention is installed in a substantially rectangular shape (not shown) so as to prevent backflow of odor while guiding drainage to the bottom of a bathroom A drainage trap main body 100 having a tub-coupling opening 110 extending downward at the center thereof, a filter cover 200 covering an upper portion of the drainage trap main body 100, A drainage pipe 300 having a drainage hole 330 formed in the wall surface 320 at a lower end of the drainage pipe 110 and a drainage pipe 300 disposed at a lower end of the wall surface 320 of the drainage pipe 300, A locking member 400 and a coil spring 500 for lifting and lowering the drainage tank 300 when drainage of sewage is completed. The detailed structure of each component is as follows.

4 and 5, the drain trap main body 100 is configured to be embedded in the bottom of a bathroom (toilet) or a veranda equipped with a drain pipe P and to be connected to the drain pipe P, And its edge is covered with a stainless steel cover material 120 having excellent corrosion resistance. The top surface of the drain trap body 100 is inclined downward from the edge to the center so as to facilitate drainage. The drain trap body 100 is formed at the center of the drain trap body 100 with a tube-coupling hole 110 extending downward. The tubular coupling member 110 is accommodated in the water pipe P. An open inferior end of the barrel-coupling opening 110 is formed with an inward flange 112 for supporting the lower end of the coil spring 500. The reference numeral 130 denotes a stepped step formed along the upper surface edge of the drain trap main body 100, and the filtering cover 200 can be securely seated inside thereof without being shaken.

The filter cover 200 is installed so as to cover the upper surface of the drain trap main body 100, and drain holes 210 are drilled in the whole area. Accordingly, the water drained to the bottom of the bathroom or the veranda flows into the drain pipe (P) through the drain holes (210) of the filter cover (200), and dirt such as hair is primarily filtered in the inflow process. The filter cover 200 is formed by press-working a stainless steel plate having excellent corrosion resistance and is disposed inside the step jaw 130 on the upper surface of the drain trap main body 100.

The drainage tank 300 is formed in a cup shape having an open upper part and a wall surface 320 and a bottom surface 310 and is disposed at a lower end portion of the drainage trap body 100 of the drainage trap body 100 As shown in FIG. An outward flange 340 is provided at an upper end of the water drainage tube 300 so that the coil spring 500 can be securely installed while preventing it from being detached from the tube-coupling hole 110. A plurality of drainage windows (330) are formed at a predetermined height from the bottom surface (310) at a predetermined interval at the central portion of the wall surface (320) of the drainage tank (300). The drain pan 300 is structured to be able to receive and close the drain pan 330 in the port-coupling port 110 when the coil springs 500 are lifted by the elastic support force. In order to fundamentally shut down the system.

The upper end of the coil spring 500 is hooked to the upper end (outward flange) 340 of the drain canister 300 and the lower end is hooked to the lower end inner wall (inward flange) 112 of the tub- So that the drain pan (300) is elastically supported in the upward direction so as to be raised / lowered by the load of sewage. That is, if the water is not drained, the water spouts 330 are lifted up by the elastic restoring force of the coil spring 500, so that the drain windows 330 are received in the barrel-coupling opening 110 and are closed. On the other hand, when drainage is performed, the drainage windows 330 are opened by lowering the drainage tank 300 while the load of the sewage water overcomes the elastic force of the coil spring 500. Therefore, the discharged sewage is discharged to the drain pipe (P) through the drain windows (330). The opening and closing operation of the drain pan 330 is determined by the elastic force of the coil spring 500 that supports the drain pan 300 upward.

The hooking member 400 is formed in a band shape at the lower end of the wall surface 320 of the water drainage tube 300 so as to limit the maximum lifting and lowering of the drainage tank 300 due to the elastic supporting force of the coil spring 500 after the drainage of water is completed. Respectively. That is, when drainage is completed, the drain canister 300 is moved up and down until the latching member 400 is caught by the inward flange 112 of the barrel-coupling opening 110. In the embodiment of the present invention, the latching member 400 is made of an O-ring made of elastic material and installed in a seating groove 321 formed in the shape of a strip at the lower end of the wall surface 320 of the drainage cylinder 300. Therefore, when the drain canister 300 is lifted and lowered, the gap between the container-coupling member 110 and the wall surface 320 of the drain canister 300 can be firmly closed.

≪ Operation of drain trap according to the present invention and description of operation effect thereof >

Next, the operation of the drain trap constructed as described above and the operation and effect of the drain trap will be described with reference to FIGS. 6 and 7. FIG.

The drainage water collected in the drainage trap body 100 is collected in the drainage trap body 100 through the drainage holes 210 of the filterage cover 200 and then drained to the drainage tank 110 through the drainage hole 110. [ (300).

As shown in FIG. 6, when the sewage flows into the drain tank 300, the drain tank 300 is lowered while the coil spring 500 is being compressed by the load, so that the drain panes 330 are exposed downward. Thus, the sewage is discharged to the drain pipe (P) through the drain window (330).

7, when the drainage is completed and most of the water in the drain canister 300 is discharged, the drain canister 300 rises again by the elastic restoring force of the coil spring 500 (see the arrow direction of Fig. 7) , And the drain window 330 is received and closed within the barrel-coupling opening 110. As a result, the communication between the drain pipe (P) and the inside of the room is fundamentally blocked, so that the back odor of the side of the drain pipe (P) can not flow backward. Particularly, the water drainage tank 300 is lifted and lowered until the latching member 400 is brought into close contact with the inward flange 112 of the tub-and-socket 110 so that the tub- So that the backflow of odor on the side of the water pipe P can be more firmly blocked.
