Robot for cleaning outer wall

Abstract

Disclosed is a robot for cleaning the outer surface of a window while performing an automatic movement along the outer window surface in a state in which the robot is vacuum-sucked onto the outer window surface. The robot includes a moving unit for moving the robot in a first direction, a direction changing unit for rotating the moving unit, to change a movement direction of the robot, and a cleaning unit mounted on at least one side of the robot. By the disclosed robot, it is possible to prevent water used to clean the window or outer wall of a building from being dropped toward a lower story. Also, the robot can run smoothly, so that it can achieve a satisfactory cleaning operation without forming spots. The robot uses a turntable system, so that it can also freely change the movement direction thereof about the center thereof up to 360 without requiring any radius of rotation, to easily approach even a dead zone. Accordingly, the robot can achieve a perfect cleaning operation. The robot has a minimum size and a minimum weight, so that it can minimize the possibility that the robot falls down during a cleaning operation.

Description

technical field [0001] [01] The present invention relates to a robot for cleaning an outer wall, and more particularly, to a robot for cleaning an outer surface of a window while automatically moving along the outer surface of the window while being vacuum-adsorbed to the outer surface of the window. Background technique [0002] [2] Although the construction of buildings with glass windows and smooth walls has been known for tens or hundreds of years, there has been no practical research into methods for effectively cleaning such glass windows and smooth walls. For this reason, the cleaning of glass windows and smooth walls is accomplished using human labor. However, it takes a lot of time to clean glass windows and smooth walls using human labor. In addition, there is the problem that personnel performing cleaning tasks are constantly in danger of falling. [0003] [3] Particularly, when people living in apartments clean the outer surfaces of windows installed in their h...
