It relates to a sewage receiving device that can be carried out.

In general, the sewage receiving inflow of sewage and sewage generated in the kitchen and the toilet into a sewage collecting tank made of a cylindrical or rectangular enclosure, and discharged to the outside by integrating such living sewage and sewage.

That is, such a conventional sewage receiving device receives living sewage generated from a kitchen, a laundry room, a veranda, a sink, and a toilet sewage, which is a fraction generated from a toilet of a toilet, and the living sewage and toilet sewage are collected through the sewage receiving device. After joining, it is discharged to the drain side connected to the final discharge pipe.

As a prior art of such a waste water collecting device, the "Euro change type waste water collecting device" of patent 10-0765446 is proposed. This prior art has a discharge passage connecting the lower surface space of the body portion to the drain port and protruding from the lower surface inside the body portion, and a flow wall partitioning the sealing tank, wherein any one of the sewage inlets and the Including the bypass mechanism that forms the odor sewage flow path by directly connecting the discharge passage is configured to enable the change of the sewage flow path inside the body portion.

Therefore, such a conventional technique is possible to change the bypass flow path for odor effluent discharge in a variety of interior of the body portion, and accordingly according to the flow path of the odor drain pipe and the discharge pipe for domestic sewage drainage introduced in various directions. It can be easily installed in response.

However, such a conventional technology has a problem in that when foreign matters are deposited inside the body part, the inside of the body part is not easy to be cleaned, and structurally complicated, so that it is difficult to actually apply to the site.

Another conventional technique is "sewage" of patent 10-0766508. This conventional technology, in connecting the toilet sewage pipe and the living sewage pipe to the sewage collecting pipe, respectively, can be connected regardless of the direction in which the toilet sewage pipe or the living sewage pipe is connected, and also, the living sewage flows in a certain amount, that is, By selectively combining the water seal function plate to allow the water to be stored to any one of the drainage paths corresponding to the position where the domestic sewage pipe is connected, it provides a sewage receiver which is very easy to plumb the toilet sewage pipe and the domestic sewage pipe during construction. .

However, such a conventional technique also has a problem in that various foreign matters are easily deposited on the sealant functional plate provided inside the sewage collecting container and cause inconvenience in cleaning and maintaining it.

On the other hand, another conventional technology different from that is "sewage" of Patent No. 10-0892620. Such a conventional technology is formed on the one side of the sewage inlet junction, the sewage inlet junction which is in contact with the standing tube, the sewage inlet junction and the sewage inlet junction is in contact with the standing tube junction, the sewage inlet in which the sewage generated in the toilet, etc., A living sewage inlet into which the living sewage flows in, a discharge port for discharging the sewage into the sewage inlet and the living sewage inlet, a discharge port for discharging domestic sewage, a backflow prevention plate for preventing the sewage flowing into the sewage inlet into the domestic sewage inlet, and A body part having a backflow preventing jaw and a drainage inducing wall for discharging the sewage introduced from the sewage inlet to the outlet; A connector coupled to the body portion and formed of a body portion and a screw portion formed of an L-shaped tube; A cap having a screw portion coupled to the screw portion of the connector and formed with a hole into which a portion of the pipe for pipe connection is inserted; And a watertight seal for binding the watertight and the pipe which are in contact with the outer diameter of the pipe for pipe connection and are inserted into the connector and pressed by the cap.

Therefore, such a conventional technique is easy to change the direction of the pipe, when embedding the sewage receiver, it is possible to excavate and bury the buried land to the minimum width, and effectively prevent the backflow of sewage into the place where living sewage flows into Will be.

However, such a conventional technique is also difficult to clean the inside when foreign matters are deposited therein, and the inclination of the pipe is easily adjusted up and down when the pipe is connected, but the discharge side is higher than the inlet side due to the number of construction rooms. It is often constructed that external sewage flows back into the interior.
