Description

Drain Trap

The present invention relates to a drain trap installed on the floor of a utility room or bathroom, and more specifically, to smoothly drain water and to completely block backflow of sewage or odor, and to easily clean the sewer pipe. The purpose of the trap is to provide a drain trap that is compatible with sewage pipes of various sizes.

In general, the drainage trap installed on the floor of the bathroom or utility room of the building is buried to be connected to the sewer pipe to discharge various living sewage into the sewage pipe, and the cover body is provided with a plurality of drainage holes perforated in the upper part of the drainage trap. It is well known that various foreign substances contained in domestic sewage were prevented from clogging the sewage pipe while blocking odor flowing back from the sewage pipe.

Accordingly, the structure of the conventional drain trap has an annular water tank (2) having a fitting connection portion (2) extending downwardly to the lower side of the center to be fitted and fixed to the inner diameter of the sewage pipe and storing a predetermined amount of water in place. 3) is formed and the hemispherical blocking member (4) is installed so as to be inserted into a predetermined depth into the water stored in the reservoir (3) of the main body 1 to block the odor flowing back from the drain and sewers, Coupled to the top of the main body 1 was made of a cover body 5 formed with a plurality of drain holes to drain while filtering foreign matter.

However, according to the conventional drain trap structure, various problems have arisen. First of all, it is difficult to completely block backflow of sewage or odor.

That is, the lower the floor or underground sewage pipes are installed, the stronger pressure is applied to the gas (including odor) generated by the sewage or sewage, in particular, when the amount of sewage increases rapidly, such as rainy season, there is a problem that backflow through the drain trap Occurred. In other words, when the sewage flows backward, when it faces the blocking member 4, the pressure flows into the room while pushing the water of the reservoir 3 by the pressure. 3) flowed into the interior of the passage.

On the other hand, when installed in a place where the use of water is low, such as a porch or a warehouse, or when there is no drainage because the water is temporarily not used, problems such as odors flow back as the water in the reservoir 3 evaporates. It became.

Another problem that has occurred in the past is that cleaning or repair of the sewage pipe is very inconvenient.

That is, since most sewage pipes are constructed in a state of being bent in the form of "L" at the bottom surface, sewage pipes are blocked by foreign substances or materials contained in the drainage accumulate on the inner surface of the sewer pipes, thereby preventing smooth drainage. In this case, it should be removed using a cleaning brush.

However, since the drain trap main body 1 is poured by cement mortar while being fitted to the top of the sewer pipe, the cleaning brush is inserted through the fitting edge 2 penetrated in the center of the drain trap main body 1 to clean it. In this case, a problem arises that it is difficult to enter the cleaning brush by the water storage tank 3, and thus various problems such as inevitably need to separate the drain trap body 1 from the cement mortar of the floor.

Another problem of the conventional drain trap structure is that it is not compatible according to the specifications of the sewage pipe during installation.

In other words, the sewage pipe to be installed in the building was installed by using a standard having a different internal diameter according to the installation position, according to the conventional drain trap, the diameter of the fitting connection (2) is different so as to meet the specifications of each sewage pipe By fabricating by selectively installed in combination.

However, according to this method, it is not only difficult to produce and logistically difficult by producing each drain trap having fitting fittings 2 suitable for sewage pipes of various standards, but also according to the type and number of sewage pipes. There was a problem that installation is very inconvenient, such as the need to calculate, and after that, various inconveniences occurred, such as the need to purchase a special drain trap suitable for the sewage pipe during repair.

The present invention has been devised to solve the above-mentioned conventional drawbacks and problems, the main purpose is to ensure a smooth drainage while blocking the odor flowing from the sewer pipe, especially the sewage amount is increased or strong according to the rainy season It is to provide a drain trap having a separate operation portion consisting of the opening and closing plate and the spring to completely block the back flow of sewage and odor, such as to block the back flow into the room by gas (including odor) pressure.

Another object of the present invention is to configure a separate operating unit to completely block the back flow of the sewage and odor, such as easy to replace or clean the operating unit by facilitating direct coupling and separation to the drain trap body, the operation It is to provide a drainage trap that is easy to repair the sewage pipe by separating the part so as to secure the space of the sewage pipe entrance.

Another object of the present invention is to provide a drain trap formed with a plurality of annular coupling grooves at equal intervals on the bottom of the drain trap body to be installed in a compatible manner for the sewage pipes having different specifications according to the installation position. will be.

In still another object of the present invention, a guide piece is formed on the upper side of the main body so that the drainage is smoothly formed, and a guide protrusion is formed in the center of the opening and closing plate of the operation unit to distribute the water flowing into the outer periphery of the opening and closing plate.
