Embodiment Construction

[0039] The cleaning method of the present invention uses the cleaning device 1 on the motor vehicle windshield 10, as attached figure 1 shown. This type of washing device comprises a first tank 2 containing a first fluid, such as a washing liquid, and a second tank 3 containing a second fluid, such as a deicing liquid.

[0040] The washer device 1 also comprises a duct system 5 connecting the first tank 2 and the second tank 3 to an opening 15 through which the first fluid and / or the second fluid is sprayed onto the windscreen 10 . The cleaning device 1 further comprises a pump system 20 designed to circulate the first fluid and / or the second fluid in the pipe system 5 until the first fluid and / or the second fluid are sprayed through the opening 15 . In this case, the pump system 20 comprises two independent pumps 21 , 22 . A first pump 21 is associated with the first tank 2 and is designed to circulate a first fluid in the piping system 5 , and a second pump 22 is associate...

Abstract

Method for de-icing a vehicle window is disclosed, 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 (a) consisting in ejecting the liquid via said openings and adapting the quantity 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<T1, an identical or different quantity of liquid is ejected.

Description

technical field [0001] The present invention relates to a method of cleaning (more particularly deicing) the windows of a vehicle, especially a motor vehicle, using a device for wiping and cleaning (or deicing) said windows. Background technique [0002] Motor vehicles are often equipped with wiper units and washer systems for wiping and washing the windshield, thus preventing interference with the driver's view of his surroundings. Units of this type generally include two wiper blades which scrape the outer surface of the windscreen, thereby removing the water present on this surface. Spray jets are located on the vehicle bonnet (or in recent versions, on the wiper blade) and are supplied with window washer fluid via a pump and piping system connected to a window washer fluid tank. [0003] For the purpose of washing the windshield (especially in the event of rain), such systems are traditionally equipped with a first tank containing the washer liquid, a system of piping c...
