Embodiment Construction

[0065] The deicing method of the present invention uses a deicing device 1 applied to a window, such as a motor vehicle windshield 10, as attached figure 1 shown.

[0066] This type of equipment comprises a first tank 2, containing a cleaning fluid, and a second tank 3, containing a deicing fluid.

[0067] The washing device 1 also comprises a pipe system 5 connecting the first reservoir 2 and the second reservoir 3 to an opening 15 through which washer and / or deicing fluid is sprayed onto the windscreen 10 . It also comprises a pump system 20 intended to circulate the washer and / or deicing fluid in the piping system 5 until it is sprayed through the opening 15 .

[0068] Here, the pump system 20 comprises two independent pumps 21 , 22 . A first pump 21 is associated with the first tank 2 and is intended to circulate cleaning liquid in the piping system 5 , and a second pump 22 is associated with the second storage tank 3 and is intended to circulate deicing liquid in the pi...

Abstract

Method for de-icing a vehicle window (10), said vehicle being equipped with a de-icing device notably comprising at least one tank containing a de-icing liquid, at least one wiper blade, openings through which said liquid is sprayed onto said window, and an outside temperature sensor, characterized in that it comprises a step consisting in ejecting the liquid via said openings and adapting the quantity Q of liquid sprayed as a function of the outside temperature so that when said outside temperature is equal to T1 a quantity of liquid is ejected and when the outside temperature is equal to T2, with T2 is smaller than T1, an identical or different quantity of liquid is ejected.

Description

technical field [0001] The technical field of the invention is methods for deicing windows, in particular motor vehicle windows, using devices for deicing said windows. Background technique [0002] Motor vehicles are often equipped with window washing and wiping systems in order to wash and wipe the windows and thus prevent the driver's view of their surroundings from being disturbed. Devices of this type generally consist of two wiper blades which wipe the outer surface of the window, windshield, thereby draining the water present on this surface. The nozzles are located at the level of the vehicle's bonnet, or in more recent solutions, on the vanes, and are supplied with windscreen washer fluid by a pump and piping system connected to the windscreen washer fluid reservoir. [0003] Some motor vehicles are equipped with deicing systems. De-icing systems typically include a standard wash and wipe system of the type previously described, and additionally include a de-icing...
