Turbo air cleaning system for vehicle windows

Abstract

A cleaning system for vehicle windows, comprising an air intake device for drawing in ambient air while driving, a compressor with integrated heating function for generating compressed and heated air, a multi-channel nozzle arrangement for directed air application in at least four directions, and a control unit for sequential or parallel activation of the nozzles, characterized in that the system additionally includes a liquid supply, wherein the liquid is combined with the air in a mixing chamber and the combined mixture is applied to the window via double nozzles, wherein the air streams are directed so that they intersect on the window surface and mechanically act on contaminants.

Description

Technical field

[0001] The invention relates to a dual cleaning system for vehicle windows, in particular windshields, which operates on the basis of compressed air and optional liquid supply. The system replaces conventional mechanical windshield wipers with a contactless, adaptive cleaning technology. State of the art

[0002] Conventional windshield wipers rely on the mechanical movement of rubber lips across the glass surface. These systems are prone to wear, generate noise, can damage the surface, and are ineffective in extreme weather conditions. Initial approaches to air-based cleaning exist, but these lack adaptive control, combined fluid supply, or multidimensional nozzle arrangements. Object of the invention

[0003] The aim of the invention is to provide a non-contact cleaning system that: • efficiently cleans the windscreen of dirt, insects, snow and ice, • works through air blast action and liquid dilution, • adapts to different levels of pollution and weather conditions, • can be integrated into existing vehicle architectures. Description of the invention

[0004] The invention comprises two independently or synchronously operable systems: System A - Turbo Air System • Air intake modules on the front, roof and side structure of the vehicle • Compressor with heating function that draws in ambient air, compresses it and heats it up to 150 °C • Distribution block for controlling the air supply in four directions: from passenger to driver, vice versa, as well as from roof to hood and vice versa. • Multi-channel nozzles with directed air output for targeted cleaning • Electronic control unit (ECU) for regulating pressure, temperature and activation sequence System B - Liquid-Air Mixing System • Tank for cleaning solution (water-foam mixture) • Dosing pump for controlled liquid supply • Mixing chamber in which air and liquid are combined • Dual nozzles that simultaneously expel air and liquid • Synchronization module that activates both systems as needed Advantages of the invention • Touchless cleaning without mechanical abrasion • Effective removal of stubborn dirt through air blast and liquid dilution • Adaptation to weather conditions through heating function • Energy efficient through the use of ambient air • Modular design for easy retrofitting Application areas • Cars, trucks, buses, special vehicles • Particularly suitable for regions with extreme weather conditions • Integration into electric vehicles with a focus on energy efficiency Extension of the invention

[0005] The invention additionally includes an intelligent night and frost protection mode which uses sensors to detect when ice formation is occurring on the windshield, the exterior mirrors or the rear window.

[0006] When the standby heating mode is activated, compressed, heated air is directed specifically onto these surfaces to remove ice and snow and ensure maximum visibility before driving. Additional components: • Temperature sensors on the windshield, exterior mirrors and rear window • Humidity sensors for detecting frost formation • Standby heating logic that is activated when the vehicle starts or according to a timer. • Air vents with rear-facing design for mirrors and rear window • ECU module with night mode detection Application areas • Cars, trucks, buses, special vehicles • Particularly suitable for regions with extreme weather conditions • Integration into electric vehicles with a focus on energy efficiency
