<P>PROBLEM TO BE SOLVED: To automatically clean a ceiling and walls inside a modular bath. <P>SOLUTION: A hose 2 is suspended from a hole arranged in the ceiling 6 of the modular bath, and is connected to a water supply source 4 for supplying cleaning water. The front end of the hose 2 is connected to a swing body 1. The swing body 1 is made of a synthetic resin foam with closed pores and has a petal shape. When the water of the water supply source 4 is discharged from the hose 2 after increasing the pressure to be 2 MPa or more by a pump P, the hose 2 is irregularly moved to generate air flows passing spaces since the spaces exist between the respective wing pieces 10 and to allow nonuniform air force to work on the respective wing pieces. Thus, the swing body 1 is irregularly performs a swing movement with the hose 2 as a center and also the hose 2 is bent in a U shape. Thus, a spray hole 3 is directed toward the ceiling 6 and spray water is sprayed toward the ceiling 6, so that the ceiling is cleaned. <P>COPYRIGHT: (C)2010,JPO&INPIT |
