Device for keeping the viewing panes clear

The innovation relates to a gate direction to keep clear the viewing windows τοη vehicles of all kinds regardless of the weather conditions, which were previously common To replace windshield wipers, defroster systems and washing systems without taking on their disadvantages »

These parts of the watch are essentially that of With the usual wipers, only part of the viewing window is kept clear, and swiveling is also possible of the wiseh sheet in the field of vision perceived as annoying "

Furthermore, there is a strong toast or tendon fall if there is a risk that the windshield wiper will no longer do its job can meet *

The defroster systems that have been used up to now also work only on parts of the lens, while the rest of the lens is iced up at least at the beginning of the journey The usual windscreen washer systems remain pure What has been said about the windscreen washer system applies in a figurative sense, since it only works in conjunction with these are useful »

According to the innovation, these disadvantages are intended to be eliminated be that through the device, depending on the type of visual impairment, either hot air, fresh air or a rinsing liquid is jetted onto the pane under pressure at an acute angle

a further embodiment of the innovation is a device used, which consists essentially of a
There is a pump that can be connected on its suction side via a three-way valve either to a fresh air intake port, a liquid container or to a heat exchanger that can be heated by the exhaust gases, and which, depending on the position of the three-way valve, can be connected via a ring line that is on the edge of the clear
to be held viewing window is guided along and the
Has jet nozzles, jets either hot air, washing liquid or fresh air under pressure on the viewing window, wherein the jet nozzles are advantageously set so that their jet at an acute angle, preferably between 30 and 60 ° on the viewing window
· Instead of the hot air heated in the heat exchanger, the exhaust gases can also be used directly. In this lall the corresponding connection of the three-way valve is connected to the exhaust line via a filter *

Depending on the shape of the window, it is advisable to
the jet nozzles either regularly over the whole
To distribute ring line or else, in particular
In the case of flat viewing panes, the arrangement of the jet nozzles on the two broad sides of the viewing pane
restrict"

The pump that generates the jet pressure is designed to be adjustable in two ways »

Through these measures it becomes possible to all in the
Practice occurring opacities either

to be excluded from the outset or in the shortest possible time Time to eliminate.

For example, on a viewing window equipped in this way, there is no. Sehnee- or ice covering may arise while incurred when the vehicle stops Sehnee "or ice covering mn in no time the whole disc can be defrosted * The rain also can not view disability occur because the rain drops as soon as they come into the area of hot air jets already atomized and be later than when they occur on the visor Terdampft, d »h» _f that the visor remains dry even in the rain or in the worst case, only a thin visibility does not impede water film has ·

If, for example, the window has been contaminated by a vehicle driving ahead, »you only need to the three-way valve can be switched so that the pump flushing liquid from the designated Container can shine on the viewing window * With a quick-acting. Solvent added Dirt is quickly washed away with detergent and then the window by switching the valve dried on hot air.

In the drawing, an embodiment of the device according to the innovation is shown schematically

The window 1 is enclosed by a ring line 2, which is equipped with jet nozzles 3,

whose beam direction at an acute angle, -preferably hits the lens 1 between 3o and 60 » The ring line 2 is connected to the pump 5 via a line 4, on the suction side of which there is a line 6 leads to the three-way valve 7. At the inlets of the Three-way valve 7 is an intake 8 for fresh air »a container 9 for rinsing fluid and a line Io connected »which leads to the heat exchanger 11. This heat exchanger is arranged around the exhaust pipe 12. The fresh air entering through its connecting piece 13 is on the artificially extended path to the connection line Io through the hot exhaust pipe 12 heated.

To counteract the hot air or the cleaned exhaust gases To protect against premature cooling, the avoidance is 2 and the lines 4 »6 and Io wholly or partially made of heat-insulating material, for example plastic manufactured
