The present invention relates to drainage for sinks that do not have to separately provide a trap that functions to block odor, in detail to the surface tension of the sewage discharged by inserting a vinyl tube inside the drain pipe connected to the drainage outlet of the main body before drainage It relates to a sink for drainage so that the rise of odor is blocked while the vinyl tube is in close contact.

In general, the drainage for the sink is installed in the drainage trap inside the drainage, by using a groove of a certain depth so that part of the sewage is always standing, to prevent the back flow of odor coming through the drain pipe.

This conventional sink drainage is provided with a single tube-shaped protruding tube protruding upward from the inner bottom of the drainage main body, the odor prevention trap unit is configured with the odor prevention cap fitted to the upper surface, the strainer and filtering The drainage cap and the like are sequentially assembled, and the side surface portion of the drainage main body is provided with a bypass pipe connection portion through which water overflows from the sink.

The water discharged by the conventional sink drainage structure having such a structure is lowered before the drainage by a method flowing over the upper surface of the protruding pipe through the odor preventing trap formed between the single-tube-shaped protruding pipe and the odor preventing cap installed on the upper surface thereof. It is drained through a drain pipe connected to the drainage, and a constant residual water is always maintained within the drainage, and the residual water can effectively block odors and pests raised from the drainage pipe by blocking the air flow between the drainage pipe and the upper part of the drainage. It is.

However, in the conventional sink for drainage, the overflow pipe connection portion through which the overflowing water flows from the sink is installed on the side of the drainage main body, and the odor prevention trap part is installed upward from the bottom of the drainage main body, and the upper part of the drain screen The upright structure of this positioning method naturally increases the height of the entire sink drainage, which causes the inside of the sink to be congested very limited, and the drainage protrudes long into the sink. As a result, there was a lot of unnecessary space, which eventually reduced the space utilization inside the sink.

In addition, in the conventional drainage consisting of an upright structure, food waste and various solids are adsorbed inside the fixed trap at the bottom and accumulate continuously over time, causing decay in itself, resulting in a bad smell. Since the trap structure is fixed, it is very inconvenient to clean and follow-up, and even to clean the inside of the drain before the fixed trap part, to remove the foreign matter, remove the drain cap, filtering, and strainer from the drain before It had the inconvenience of cleaning the inside before drainage.

In order to solve the problems of the prior art sink for drainage, Patent No. 0642591 has been disclosed that the name of the invention 'sink drainage with a separate separate drain trap'.

As shown in FIGS. 4 and 5, the filter panel 110 and the main body cover 103 are formed in the main body 100 before the drainage, the trap part and the drain part are integrally formed, and the trap part is disposed therein. A deodorizing plate is formed in half and has a drain trap 120 having a drain trap cap 121 coupled thereon, and the drain trap 120 is disposed on the drain hole 102 formed on one side of the drainage main body 100. It is connected, the other side is formed with a connecting portion 101 is connected to the overflow pipe, it is possible to prevent the backflow of the odor and at the same time to obtain the effect of preventing the accumulation of food debris in the main body before draining the sink It is to improve the problem of drainage.

However, according to the prior art sink drainage drain drain trap 120 has to be mounted separately to the drainage main body 100, the overflow pipe was also inconvenient to connect to the drainage main body. In addition, since the inside of the sink is very congested as in the prior art, it is not only limited to the wide utilization of the sink storage space, but also has to produce a drainage trap separately.

The present invention has been devised to improve the problems of the prior art as described above, it is not necessary to separately install a trap that functions to block odors to the outside of the drainage main body, the inside of the drain pipe connected to the drain opening of the drainage It is to provide a sink for drainage so that the rise of odor is blocked by the close contact of the vinyl tube by the surface tension of the sewage discharged by inserting the vinyl tube.

In order to achieve the object as described above, the present invention, a drain pipe main body (1) formed with a drain hole (2) to protrude through the lower side, and a drain pipe coupled to the flange (5) connected to the drain hole (2) (4) and comprises a vinyl tube 10 communicated with a predetermined length, the vinyl tube 10 is coupled to the flange 5 in the state wrapped around the upper end on the outer periphery of the drain pipe (4) It is fixed by and inserted into the drain pipe 4, characterized in that the inner surface is in close contact by the surface tension of the discharged sewage to block the odor.

In addition, the vinyl tube 10 is formed of a soft plastic paper in accordance with the inner diameter of the drain pipe 4, characterized in that the fold line 11 is formed on both sides in the longitudinal direction.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. The present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, only this embodiment to make the disclosure of the present invention complete and to those skilled in the art to fully understand the scope of the invention It is provided to inform you.

1 is an exploded perspective view illustrating a coupling state of a vinyl tube and a drain pipe configured before the sink drain according to the present invention, and FIG. 2 is a cross-sectional view illustrating a coupling state of the sink drain according to the present invention.

The drainage main body 1 according to the present invention has a drain hole 2 formed to penetrate and protrude to the lower side, and the drain hole 2 has a drain pipe 4 and a predetermined length to which a flange 5 to be connected is coupled. It is configured to include a vinyl tube 10 while communicating.

The drainage port 2 may be formed at the center of the bottom surface of the drainage main body 1, but when the drainage drainage body 2 is not seen when viewed from above the drainage main body 1, the lower side is better. It is preferable to form at.

It is preferable that the inside of the main body 1 before the drainage further includes a strainer 3 for filtering food waste.

The vinyl tube 10 is a flange that is coupled to the top of the drain pipe (4) is inserted into the inner wrap around the upper end to the outer circumference of the drain pipe 4, as shown by the double-dot chain line in FIG. By coupling 5) to the drain port 2, the upper end of the vinyl tube 10 is fixed by the step formed in the drain port 2 and the upper end of the drain pipe 4.

As shown in FIG. 2, the vinyl tube 10 inserted into the drain pipe 4 is maintained in a folded state by the fold line 11 from the lower end portion to the upper predetermined portion portion.

In FIG. 2, the dotted line arrow indicated inside the drain pipe 4 indicates the direction of odor coming up along the drain pipe 4.

The vinyl tube 10 is formed of a soft plastic paper in accordance with the inner diameter of the drain pipe 4, to form a folding line 11 on both sides in the longitudinal direction to maintain the folded state by the folding line (11) It is preferable that the length is about 20-30 cm.

Hereinafter, the odor blocking function of the vinyl tube will be described with reference to FIG. 3.

The sewage discharged from the sink bowl is discharged from the food waste by the strainer (3) through the vinyl tube (10) inserted into the drain pipe (4) through the drain hole (2), at this time, as shown in Figure 2 The vinyl tube 10, which was maintained in the folded state by the fold line 11 to an upper predetermined portion, is opened while being naturally unfolded by the water pressure of the discharged sewage, and is smoothly drained.

Here, as the sewage passes through the inside of the vinyl tube 10, water is buried on the inner surface of the vinyl tube 10, and discharge is completed while the sewage passes through the lower end of the vinyl tube 10, and FIG. As shown in the drawing, the vinyl tube 10 returns to its original folded state, and the inner surface of the lower part is brought into close contact with the surface tension of the sewage buried on the inner side, and the upper part of the vinyl tube 10 is gradually raised to a certain portion. Since it is brought into close contact with each other, it becomes a sealed state, thereby preventing odors generated through the drain holes 2 by blocking odors coming up through the drain pipes 4.

On the other hand, when the vinyl tube 10 is used for a long time, the fine particles of the food residues are buried in the inner surface slippery and the sewage is less likely to adhere to the adhesion, so periodically replace the vinyl tube 10 with a new one Can be used.

In the present invention, it is not necessary to form a connection portion connecting the overflow pipe for preventing the water overflow of the sink ball in the main body 1 in the present invention, which is disclosed in Utility Model Registration Nos. 392270 and 408040 filed by the present applicant.
