Description

Drain trap for a sewer

The present invention relates to a drain trap for domestic sewage that can block not only odors naturally generated in the process of discharging various kinds of water for living in a building, but also pests and insects from entering.

In general, domestic sewage discharged from single-family homes as well as multi-family houses or apartment houses is discharged to the outside through drainage lines configured in various forms according to uses.

Since these types of living sewage contain various organic matter and decay easily, a bad odor is generated and an unpleasant odor is induced into the room along the drain pipe, and pests such as cockroaches are introduced. A sphere is installed or a U-shaped cutoff pipe is generally installed and used.

However, it is difficult to manage practically due to the inconvenience of disassembling and cleaning from time to time due to the continuous accumulation of food waste. Therefore, several limitations follow.

In relation to such a drain trap, the technology disclosed in Korean Patent Registration No. 0740525 connects the deodorizing means to the main body and allows the deodorizing means to be separated from the main body and then cleaned by allowing the lower side to be opened, but separating the deodorizing means from the main body There is a drawback in that it is difficult and it is very difficult to accurately combine the deodorizing means again after cleaning the foreign substances in the trap.

In addition, in the case of Patent Registration No. 0908323, the sewage flowing in from the streamline trap stays and prevents the odor of toilet sewage from flowing into the inlet pipe. There is a problem of backflow due to naturally occurring odor while staying, and it is possible to clean foreign substances that accumulate on the bottom of the streamlined trap from the outside, but it is impossible to clean foreign substances that accumulate in the domestic sewage inlet and the pipe coupling.

In addition, in the case of the drainage trap disclosed in Patent Registration No. 1147044, it is designed to block odors from entering the room, but foreign substances such as hair and various debris that are mixed with sewage and drained are continuously placed on the blocking plate and stored inside the water level retainer. If it is continuously accumulated, the blocking plate cannot normally perform the lifting action, and it is impossible to block the bottom of the drain hole by the blocking plate, so there is a problem that the backflow of odor cannot be prevented.

Registered Patent No. 0886962 (registered on Feb. 26, 2009) - A trap and a trench provided with the trap. Registered Patent No. 1479418 (Registered on Dec. 29, 2014) - Backflow odor blocking device. Registered Patent No. 1757620 (registered on July 7, 2017) - Drainage trap for preventing odor backflow.

The present invention is to solve the problems of the prior art as described above, and an object of the present invention is to suppress the reverse flow of odors as well as the entry of pests and insects by using a water collecting tub, and living through the inlet and outlet pipes. An object of the present invention is to provide a drain trap for domestic sewage that can smoothly circulate sewage as well as easily perform cleaning and maintenance.

The present invention for achieving this object includes a water inlet pipe through which domestic sewage is introduced, a water collecting pipe for allowing the sewage to flow out after being temporarily stored and at the same time preventing the odor of sewage from flowing back, and the It is connected to the other side and consists of a water outlet pipe for discharging sewage, and a cover is provided to be detachably attached to the upper end of the water collecting tank and at the same time a blocking plate is vertically inserted into the rail groove and assembled, and the center of the water inlet pipe is the water outlet. It is set higher than the center of the tube.

In addition, an inclined surface is formed on the inner surface of the bottom of the water collecting container toward the water outlet, and an extension flange having a male screw part is formed on the outer surface of the bottom of the water collecting container so that the auxiliary cap can be detached and attached.

According to the present invention, because the lower end of the blocking plate installed in the water collecting tank is always immersed in the sewage surface, the reverse flow of odors as well as the entry of pests or insects can be fundamentally suppressed by the above-described features.

In addition, since the inner surface of the bottom of the water collecting tank is inclined toward the water outlet, domestic sewage can be circulated smoothly through the water inlet and outlet pipes, and cleaning and maintenance can be performed easily by simply installing it inside the building itself.
