Problems solved by technology

[0012] Therefore, using wires having the same resistivity for the first pipe 6 and the second pipe 7 cannot provide the same power per unit length for the first pipe 6 and the second pipe 7, and thus cannot Brings roughly even heating of the windshield washer fluid at the level of the two wiper blades

Embodiment Construction

[0033] According to the invention, radiator means are arranged on at least one of the secondary conduits for supplying washing liquid, and the wires associated with each secondary conduit have substantially the same electrical resistivity. In the example shown, the radiator arrangement is only arranged on one secondary duct (the shorter one). Obviously, radiator means may be arranged on each secondary duct, and the heat dissipated by each set of means is a function of the size of the corresponding wire on which these means are mounted.

[0034] Reference attached image 3 , for clarity, again used with the attached figure 1 The same reference numerals. The washer liquid distribution and heating system 14 according to the invention comprises an additional electrical resistance 15 which is arranged on the shorter first conduit 6 .

[0035] By increasing the overall resistance of the first conduit 6, this additional resistance 15 makes it possible to use wires 13 with the same...

Abstract

System for distributing washing liquid in a cleaning device comprising two sets of nozzles, which system includes a first secondary pipe (6) and a second secondary pipe (7) for feeding the washing liquid to the nozzles, which first and second secondary pipes, hydraulically connected to a main pipe (3) extending from a washing liquid tank (4), each include at least one circulation tube (11, 12) for the washing liquid and a conductive element (13) embedded in its mass, characterized in that at least one heat dissipator apparatus (15) is provided in at least one of the two secondary pipes.

Description

technical field [0001] The invention relates primarily to a system for distributing and heating washer fluid installed in a cleaning device mounted on a vehicle, in particular a motor vehicle. In particular, the invention relates to such systems for vehicle window wiper devices. The invention also relates to a vehicle equipped with at least one such system. Background technique [0002] In the present invention, "washer fluid" refers to any fluid known to those skilled in the art that is suitable for cleaning devices installed on vehicles, in particular any windscreen washer fluid. [0003] Depending on the embodiment, the washer fluid can be dispensed via fixed nozzles arranged close to the intersection of the bonnet and the window to be wiped, or via the level of the nozzles on the wiper blade, which makes it possible to quickly wipe the sprayed on the window. washer fluid, thereby reducing the time interval during which the driver's vision is impaired by the presence of...
