PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.

[0001] The present disclosure relates to a glass wiping equipment of a vehicle, and more particularly relates to the wiping equipment for cleaning of side windows of a vehicle for clear visual through the side windows.
BACKGROUND OF THE INVENTION
[0002] Side windows have been used for side visual. However, during certain situations like rainy season or winter, a lot of moisture is accumulated at the side windows that reduces driver’s vision from the side windows. It is to be noted that condensation inside a vehicle is cleared using an air conditioner (AC) or a heater. However, the heavy droplets, moisture and dirt accumulation will be there from outside of the side window which blocks the driver’s vision thereby increasing probability of accident. Further, in order to clean droplets and dirt from the window glass, driver has to stop the vehicle and wipe the window glass manually. Hence, there remains a need of an efficient mechanism for cleaning side windows of a vehicle.
OBJECT OF THE INVENTION
[0003] The principal object of the embodiments herein is to provide a glass wiping equipment for cleaning of side windows for clear visual through side windows of a vehicle.
[0004] Another object of the embodiments herein is to twist a foam using from its original position a roller and a spiral spring thereby releasing water observed by the foam in a water duct while moving the window glass in in a downward direction during an opening operation of the side window of the vehicle.
[0005] Yet another object of the embodiments herein is to oppose a rotation of the roller to retain the foam the original position thereby allowing

the foam to wipe the window glass due to surface contact while moving the window glass in in an upward direction during a closing operation of the side window of the vehicle.
[0006] Yet another object of the embodiments herein is to automatically drain the water collected at the water duct through a drain plug when a door of the vehicle is opened.

When the user presses the switch (107) in a first condition such as pressed downwards then the opening operation is performed. Further, when the user presses the switch (107) in a second condition such as pressed upwards then the closing operation is performed.
[0036] If it is determined that the user presses the switch (107) to perform the opening operation of the side window (107), then at step 206, the method includes activating the motor (106) and moving the window glass (101) in a downward direction during the opening operation. At step 208, the method includes absorbing by a foam (102) water on the window glass (101) while moving the window glass (101) in the downward direction. At step 210, the method includes twisting the foam (102) from its original position by rotating a roller (104) attached to the foam (102) thereby releasing the observed water

in a water duct (105). The foam (102) is twisted till the roller (104) is in contact with the window glass (101). At step 212, the method includes retaining the foam (102) its shape due to the spiral spring (103) after crossing a certain position or slipping from the window glass (101) during the opening operation.
[0037] Further, if it is determined that the user presses the switch (107) to perform the closing operation of the side window (107), then at step 214, the method includes activating the motor (106) and moving the window glass (101) in an upward direction. At step 216, the method incudes opposing the rotation of the roller (104) by a spiral spring (103) connected to the foam (102) to retain the foam (102) in the original position. At step 218, the method includes allowing the foam (102) to wipe the window glass (101) due to surface contact while moving the window glass (101) in the upward direction.
[0038] At step 220, the method includes detecting whether a door of the vehicle is opened. In response to detecting that the door of the vehicle is opened, then at step 222 the method includes automatically draining the water collected at the water duct (105) through a drain plug (111) connected the water duct (105) when the door of the vehicle is opened. In case if it is detected that the door of the vehicle is not opened, then the steps method repeat the steps from 202.
