Description

Window system with external glass window washer {Window door system with external glass window washer}

The present invention relates to a window system having an external window cleaning unit, and more particularly, to an insect screen having a first cleaning unit for wiping the outer surface of a second window, and a second window to wipe the outer surface of the first window. The present invention relates to a window system having an external window washing unit that is provided with a second cleaning unit and can simultaneously wipe the outer surfaces of a first window and a second window when the second window is opened or closed.

In general, windows are an important component of buildings that play a role such as indoor lighting by sunlight, outdoor viewing function, wind and water blocking, sound insulation, and insulation, and are used in high-rise buildings as well as general homes and large-scale apartments. .

Since dust or foreign matter accumulates on the inner and outer surfaces of the glass window where the window is used over time, it is necessary to periodically clean the window to maintain the function of the window.

However, in general, it is relatively easy to clean the inner surface of a window installed on the outer wall of a building, but in the case of a high-rise building, it is not easy to clean the outer surface of a window.

Since such exterior cleaning of glass windows is generally performed by installing an elevator on the roof and moving downward along the outer wall of the building, the windows cannot be opened or closed during the cleaning time, and immediate cleaning is performed at the desired time by the user using the building. is impossible, and there is a problem in that a separate cost for using the company is added.

In order to solve this problem, recently, a technology for a device that is individually attached to a window to clean the outer surface of the window has been developed, and one of the technologies for such a window cleaning device is registered in Patent Registration No. referred to as 'prior art') is disclosed.

The prior art is configured to be provided at an end of an outdoor window relatively closer to the outdoor side of a pair of windows to wipe the outer surface of the indoor window in the process of moving the window in the left and right directions.

However, in the case of the prior art, since only the outer surface of the indoor window can be washed, the outdoor window still cannot be washed.

Registered Patent Publication No. 10-1913798 (registered on October 28, 2018)

The present invention was created to solve the problems of the prior art, and the problem to be solved in the present invention is provided with a first washing unit for wiping the outer surface of the second window on the insect screen, and the first window on the second window. The present invention relates to a window system equipped with a second cleaning unit for wiping the outer surface of a window, and an exterior window cleaning unit capable of simultaneously wiping the outer surfaces of a first window and a second window when the second window is opened or closed.
