PURPOSE: A large window outside glass cleaner is provided to simply clean an outside glass of a high-rise building, an apartment and so on by only operating a lever after connecting the cleaner to a water tap. CONSTITUTION: A large window outside glass cleaner is composed of a water inflow control device(110) and a cleaning bar(400). The water inflow control device rotates by 90 degrees and is controlled with forward water inflow pipes(240,210) and backward water inflow pipes(220,230) by an external valve. The cleaning bar is moved by movement of a piston inner bundle(120). The piston inner bundle moves according to the direction of the external valve. Water is flowed into a piston(130) and the water is flowed into the cleaning bar if the cleaning bar moves from left to right. An outside glass is cleaned by jetting water through an injection port(410). |
