Abstract

This washing machine for a railway vehicle includes a water texturing system, mixing water with particles able to produce textured water having super-hydrophoby properties making it possible to implement a lotus cleaning effect on the surface on which the textured water flows; a textured water spraying system, fed by the water texturing system and using at least one appropriate spraying device to spray the textured water on a surface of the railway vehicle to be cleaned.

Claims (10)

1. A washing machine for a railway vehicle, the washing machine comprising:

a water texturing system, mixing appropriate particles with water to produce textured water having super-hydrophoby properties, said appropriate particles being microbeads of fluorinated glass, lycopodiums, or soot; and

a textured water spraying system, fed by the water texturing system and using at least one appropriate spraying device to spray the textured water on a surface of a railway vehicle to be cleaned,

wherein the water texturing system includes a clean water reservoir and a particle container, as well as a water texturing machine capable of mixing a clean water supplied by the clean water reservoir with particles supplied by the particle container to produce the textured water, and

wherein the water texturing machine includes a tank, the bottom of which is filled with the clean water, and a drum, rotated using a motor, and one wall of which is provided with cells allowing the clean water to circulate between an inside and an outside of the drum, the particles being introduced from the container to the inside of the drum, the cells being smaller than the particles so as to keep the particles inside the drum.

2. The washing machine according to claim 1 , wherein the textured water spraying system includes a plurality of spraying bars.

3. The washing machine according to claim 2 , wherein each spraying bars includes an air spraying system to spray hot or cold air, optionally pulsed.

4. The washing machine according to claim 1 , the washing machine having no mechanical washing means.

5. The washing machine according to claim 1 , including a dirty textured water recovery system.
