WINDOW CLEANING APPARATUS AND METHOD FOR CONTROL MAGNETIC FORCE OF THE APPARATUS

摘要

A device for cleaning a window comprises a first cleaning unit; a second cleaning unit; a first magnetic module; a second magnetic module; a magnetic force control unit; and a magnetic force sensing device. The first cleaning unit is attached to one side of the window. The second cleaning unit is attached to the other side of the window. The first magnetic module is included in the first cleaning unit. The second magnetic module is included in the second cleaning unit. The magnetic force control unit controls the magnetic force between the first magnetic module and the second magnetic module. The magnetic force sensing device is distinguished from the first cleaning unit and the second cleaning unit. The magnetic force sensing device measures the magnetic force of the first magnetic module or the second magnetic module. A method for controlling the magnetic force of the device for cleaning the window comprises a step for measuring the magnetic force of the second cleaning unit through the magnetic force sensing device; a step for transmitting the magnetic force measured by the magnetic force sensing device to the first cleaning unit; a step for calculating the height of the first magnetic module or the second magnetic module through a control unit of the first cleaning unit; and a step for displaying a set of magnetic force control information generated by the measured magnetic force.
