BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a drain pipe having an odor backflow prevention function,

Generally, a drain trap is used as a device to store or drain water in a sink or bathtub. These drainage traps are used in various ways in order to filter the foreign substances in the sewage and to block odor from flowing back from the pop-up pipe.

[0004] As shown in FIG. 1, a nut-integrated drain pipe includes a drain hole 41 (see FIG. 1) penetrating a certain point of the sink 40, A connection pipe 20 which is connected to the lower part of the pop-up pipe 10 and is connected to a drainage water or a fresh water supply pipe provided in the inside of the pop-up pipe 10 to flow into the drainage hole 41; And a pop-up switching means 30 for interrupting the pop-up switching means 30.

The pop-up tube 10 has a tubular body 11 formed to have a longer length than the depth of the drainage hole 41 penetrated through the washstand 40 and formed with threads on the lower end peripheral surface, The connecting pipe 20 has a tubular body portion 21 having a threaded portion 22 formed on an inner peripheral surface of the upper portion of the connecting pipe 20, And a nut 23a formed on the lower surface of the wash basin 40 to be in tight contact with the lower surface of the wash basin 40. As shown in FIG.

A rubber packing member 50 having elasticity for preventing leakage of water between the drain hole 41 and the pop-up pipe 10 is provided at a portion where the latching jaw 12 and the washstand 40 are in contact with each other, Is interposed.

However, in the above-described drain pipe, the pop-up opening / closing means 30 is connected to the pop-up pipe 10 connected to the sink 40, so that water can be received or drained from the sink during the operation of the pop- There is a disadvantage in that the smell that flows back to the drain hole 41 can not be caught when the pop-up opening / closing means is opened.

It is an object of the present invention to overcome the above-mentioned problems of the related art, and it is an object of the present invention to make it possible to maintain a pleasant environment by completely blocking the backflow of odor and to facilitate connection work between the water pipe and the piping, The present invention also provides a drain pipe having an odor backflow prevention function that can prevent reverse flow of odor without remaining water in a pipe and can be easily mounted on a drain pipe.

In order to achieve the above object, the present invention provides a deodorizing unit, comprising: a support pipe formed around a circumference of a side of an inner side of a drain pipe connected to a sink, etc., to support the deodorization unit, The present invention provides a drain pipe having a function of preventing the backflow of odor, which is formed by a connection structure of a sealing plate installed to block the upper and lower portions of a drain pipe to which the body is attached while being connected to the body through a fixing member supported via a spring.

In addition, the body of the present invention provides a drain pipe having an odor backflow preventive function in which a lower end of a pop-up pipe is connected to an upper portion of the body, and a connection pipe for covering the cap when not in use is further integrally provided.

In addition, the drain pipe of the present invention provides a drain pipe having an odor backflow prevention function in which a corrugated pipe is integrally connected to a lower one side so that the length of the drain pipe can be adjusted in the vertical direction.

The present invention provides a drain pipe having an odor backflow prevention function in which a lower end of a drain pipe and a branch pipe are connected to a lower end of the drain pipe so that the drain pipe can be drained to the side at a lower end thereof.

In addition, the drain pipe of the present invention provides a drain pipe having an odor backflow preventive function in which the drain pipe is installed so that the sealing plate is separated when the pop-up pipe seals the drain hole of the sink, thereby pressing the fixing piece.

Further, the sealing plate of the present invention provides a drain pipe having an odor backflow preventive function in which the central portion in the horizontal direction is raised so that the water drainage can be easily formed from the center to the edge side.

As described above, according to the present invention, it is possible to maintain the pleasant environment by completely blocking the backflow of the odor, to easily connect the water pipe and the pipe regardless of the direction and the interval, to prevent the backflow of the odor without remaining water in the pipe So that it can be easily mounted on a drain pipe.
