Abstract

An auto-washing type window is provided to prevent the formation of a blind spot and to improve the quality of washing a glass window by adhering a blade closely to the whole area of a glass window at the uniform pressure, and to increase the convenience in use and the service life of equipment by controlling rolling movement when a blade is pushed backward. The invention relates to an auto-washing type window equipped with a wiper unit for washing the front of the outer surface of a glass window, wherein the wiper unit contains a blade(10) contacted with a glass window(5) and equipped with a holding portion, a profile composed of a blade holder holding the holding portion of the blade and a support placed in a frame, and a frame provided with a profile installation space. The wiper unit is composed of profile segments divided into many sections to make the blade partially bendable correspondingly to a bend of the outer surface of the glass window and connected to be movable individually, and a primary elastic member and a secondary elastic member are installed on the front and the rear of the profile segment.

The present invention relates to a self-cleaning window provided with a wiper unit, and in particular, even if a curved portion is partially present on the outer surface of a windshield, the blade is closely contacted with an even pressure over the entire area of the windshield including the bent portion, And to improve the cleaning performance of the windshield, and to prevent the flow of the blade even when the blade is pushed backward, thereby improving the feeling of use and the life of the appliance.

As the buildings have become larger and larger, especially, it has become difficult for people to clean outdoors side windows, a washing type window in which cleaning is automatically performed when the windows are slid is disclosed in Utility Model Registration Nos. 323292, 342671, 347986 have.

In the conventional techniques, a wiper unit is provided in contact with the window in a direction perpendicular to the window, and the glass window is relatively moved in the horizontal direction relative to the wiper unit to remove foreign substances from the glass window surface. There are also.

As shown in FIG. 6, the conventional wiper unit 101 includes a blade 110 which is in contact with a glass window 5 and has a holding part 113, a holding part 113 of the blade And a frame 130 having a profile installation space and a profile 120 composed of a blade holding portion and a support portion received in the frame 130.

In order for the wiper unit to effectively perform the cleaning of the windshield, the blades of the windshield must be uniformly applied over the entire area of the windshield. However, the windshield surface has unevenness due to unevenness of the windshield, Is supported in one profile (120).

Therefore, the blades can not be brought into close contact with the surface of the windshield having uneven flatness, so that portions that do not contact with each other are generated, and such a portion remains as a cleaning blind spot where foreign matter is not removed even if the wiper unit moves relative thereto .

In addition, when the blade 110 is pushed rearward by applying pressure only to the front side in a direction in which the blade 110 is in close contact with the windshield, there is a problem that the blades are swirled to cause a deterioration of the feeling of use and shorten the service life of the device.

In order to prevent the blade 110 from rising from the surface of the windshield, the press bolt 170 is provided to press the center of the profile 120. However, There is a problem in that the contact between the electrodes can not be uniformly performed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems,

SUMMARY OF THE INVENTION It is an object of the present invention to provide a washing machine capable of preventing the generation of a washing rectangle area and improving the cleaning quality of a window by providing an even pressure on the entire area of a window including a curved part even if a curved part is partially present on the outer surface of the window. In order to provide a self-cleaning window.

Another object of the present invention is to provide a self-cleaning window for preventing the flow of movement even when the blade is pushed backward, thereby improving the feeling of use and the service life of the device.

According to an aspect of the present invention,

A wiper unit for cleaning the front surface of the windshield is provided.
