JP4166557B2 - Drain trap with cleaning port for disposer - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a garbage disposal system using a disposer.
[0002]
[Prior art]
Conventionally, there are P traps and S traps as drain traps connected to the discharge pipe of the disposer, and a side pipe with a cleaning port as shown in FIGS. 1 and 2 is provided on the secondary side of each trap. The extension pipe is connected to the branch pipe, and the branch pipe is normally closed by the lid. However, when cleaning, remove this lid and insert a washing nozzle, hose, etc. from the cleaning port, into the downstream drain pipe. The slime adhering to the wall was removed with a high-pressure jet and washed away.
[0003]
[Problems to be solved by the invention]
Washing nozzles and hoses that perform washing with a high-pressure jet as described above are required to have pressure resistance, so they are often manufactured from hard metal pipes, and on the other hand, branch pipes equipped with cleaning ports are installed on the side. The pipe is usually made of hard plastic, and the thickness of the branch part between the extension pipe main body and the branch pipe is not necessarily thick, so that the branch part is worn and damaged by repeated insertion and removal of the cleaning nozzle and hose. An accident occurs in which water leaks out of the pipe. In addition, during cleaning with a high-pressure jet, the waste liquid may flow backward due to obstacles in the pipe and overflow from the cleaning port, contaminating the surroundings. In order to prevent such an accident, the structure of the entire extension pipe should be made thick and sturdy, and a check valve or the like may be provided at the cleaning port.
[0004]
[Means for Solving the Problems]
In view of this, the present invention provides a drain trap with a cleaning port for a disposer that extends from the cleaning port through the inner wall of the branch pipe to the connecting portion of the extension pipe with a branch pipe provided with the cleaning port on the side. A rubber bush having a cylindrical portion and wall ends that are in close contact with the wall surface is inserted and closely attached to the branch pipe portion of the extension pipe, and particularly, the connection portion between the branch pipe and the extension pipe is covered. A splash guard made of a chrysanthemum cut film is stretched on the inner wall of the rubber bush near the cleaning port.
[0005]
【The invention's effect】
Since the present invention is configured as described above, in the disposer, there is no need to configure the discharge-side extension pipe including the cleaning pipe branch pipe with a particularly thick wall, but the rubber bush is simply inserted into the branch pipe inner wall of the extension pipe. By simply inserting a cleaning nozzle or hose from this cleaning port, cleaning work on the disposer discharge side can be performed without any problems. There is no such thing as wearing out the connecting part and leaking sewage from this part. Also, if it wears out, it is only necessary to replace the rubber bush.
[0006]
Further, in another embodiment of the present invention, since a splash guard made of a chrysanthemum cut film is stretched on the inner wall of the rubber bush near the cleaning port, when a cleaning nozzle or hose is inserted from this cleaning port, The membrane piece with chrysanthemum cut close to the hose and acts like a check valve, substantially preventing leakage of sewage from the inside of the extension tube, causing the waste liquid to flow backward and overflow from the cleaning port In advance.

DETAILED DESCRIPTION OF THE INVENTION
A drain trap with a cleaning opening for a disposer according to the present invention is shown in FIGS. 1 and 2, and in particular, an embodiment of a rubber bush used for the trap of the present invention is shown in FIG.
[0008]
In the drain trap 1 with the cleaning port for the disposer, these extend pipes 4 having the branch pipes 3 provided with the cleaning ports 2 are installed on the side surfaces from the cleaning port 2 through the inner walls of the branch pipes 3 to the connecting parts with the extension pipes 4. A rubber bush 7 having a cylindrical portion 5 and outer flange portions 6 and 6 ′ in close contact with the outer wall surface is inserted and brought into close contact with the branch pipe 3 portion of the extension pipe 4, and in particular, a connection portion between the branch pipe 3 and the extension pipe 4. It is comprised so that it may coat | cover.
[0009]
A splash guard 9 made of a chrysanthemum cut film 8 is stretched on the inner wall of the rubber bush 7 near the cleaning port 2. When the cleaning nozzle 10 is inserted from the cleaning port 2, each piece of the chrysanthemum-like cut-in membrane 8 is in close contact with the periphery of the hose of the cleaning nozzle 10 and acts in the same way as a check valve. Substantially prevent leakage.
