Abstract

The present solution relates to an arrangement and a method for cleaning windows and/or rear view mirrors with compressed air. The arrangement comprises nozzles arranged along the rim of the windows and/or mirrors. The method for cleaning windows and/or rear view mirrors comprises the step of spraying compressed air over the surface as a mist. The compressed air is preferably mixed with washer fluid. Clean compressed air subsequently blows the surface clean.

CLEANING OF WINDOWS AND/OR REAR VIEW MIRRORS

ABSTRACT

The present solution relates to an arrangement and a method for cleaning windows and/or rear view mirrors with compressed air. The arrangement comprises nozzles arranged along the rim of the windows and/or mirrors. The method for cleaning windows and/or rear view mirrors comprises the step of spraying compressed air over the surface as a mist. The compressed air is preferably mixed with washer fluid. Clean compressed air subsequently blows the surface clean.

BACKGROUND ART

Snow, dirt, sand, water and other pollutants may reduce the visibility when driving a vehicle and may thus affect the safety for the driver and the surrounding traffic. Vehicles comprise different cleaning systems for handling pollutants, such as windscreen wipers and electric heaters for cleaning the rear view mirrors. These cleaning solutions do however not solve all problems caused by pollutants. For example, there are areas which are not reached by the windscreen wipers, the electric heaters takes too long to start and there is no solution at all for cleaning side windows. Side windows may for example be much polluted while overtaking other vehicles in bad weather.

TECHNICAL SOLUTION

The present solution relates to an arrangement and a method for cleaning windows and/or rear view mirrors with compressed air. The compressed air may be distributed over the polluted surfaces by nozzles arranged along the rim of the window and/or mirror. In order to maintain a substantially constant pressure, the compressed air may have to be pressure regulated. If the surface is assessed to be much polluted, the pressure of the compressed air may be increased. The compressed air may also be heated and/or diluted with for example washer fluid, in order to improve the effect and to prevent freezing.

According to an aspect of the present solution the method for cleaning windows and/or rear view mirrors comprises the step of spraying compressed air over the surface as a mist. The compressed air is preferably mixed with washer fluid, whereby clean compressed air subsequently blows the surface clean. This way, the safety and the comfort of the driver and the passengers are increased. If the method for cleaning relates to a windscreen and/or rear window, the method further comprises the step of subsequently activating the wipers for the windscreen and/or the rear window respectively.

According to an aspect of the present solution the cleaning, and thus the distribution of the compressed air, may be controlled based on rain sensor automatics. Sensors on the polluted surface thus sense when the polluted surface needs to be cleaned and the cleaning is activated automatically.  Alternatively, the compressed air is distributed over the surface automatically when a sensor senses that the driver or a passenger looks at said surface. In the case where the driver of the vehicle and a passenger looks at different surfaces at the same time, cleaning of...
