Description

  The present invention relates to an apparatus for cleaning an inner wall of a pipe with high-pressure water.

The drain pipe of the sink (sink) of a kitchen in a general household has a problem that fine garbage components adhere to the inner wall and are stacked, which hinders drainage. Therefore, it is necessary to periodically clean the inner wall of the drain pipe. However, in the conventional cleaning device, the hose is inserted by jet water jetted obliquely backward from the nozzle at the tip of the hose inserted into the drain pipe. However, in order to turn the nozzle and move forward by switching the turning direction, various arrangements are made to the nozzle hole arrangement of the nozzle, and it is troubled by experienced workers. It was necessary to operate a large hose.
