  • an inner wall of the hollow body opening is made hydrophobic.
  • the hydrophobic material of the hollow body is not wetted, so that the capillary force and the centrifugal force have in opposite directions, so that based on the balance of forces between the capillary force and the centrifugal force, the first speed can be calculated as a minimum speed, which is required so that the centrifugal force exceeds the radially inwardly acting capillary force and thus the liquid can pass from the liquid space to the surface of the hollow body.

  • the hollow body can either itself, at least in the region of the hollow body openings, be made of the hydrophobic material or be coated with the hydrophobic material.
  • the hydrophobic property of the hollow body causes the water within the hollow body openings has a contact angle greater than 90 ° to the inner wall of the hollow body opening, so that the capillary force is turned in the direction of the liquid space and thus precludes the centrifugal force. This can lead to the previously explained equilibrium of forces between the capillary force and the centrifugal force.
  • the hollow body openings may preferably have a diameter of 0.5 ⁇ m to 2 mm exhibit.
  • openings with such a diameter have a sufficiently strong capillary effect, ie, a sufficient rise height of the liquid within the hollow body opening, in order to enable the functioning according to the invention.

Abstract

L'invention concerne un appareil de nettoyage (1), en particulier un appareil de nettoyage de sols, muni d'un rouleau de nettoyage (2) pouvant tourner autour d'un axe de rotation (x) pour le traitement d'une surface à nettoyer. Le rouleau de nettoyage (2) est au moins en partie réalisé sous la forme d'un corps creux (3) à l'intérieur duquel se trouve une chambre à liquide (4), le corps creux (3) présentant au moins une ouverture (5, 10) permettant au liquide de sortir de la chambre à liquide (4). L'invention vise à obtenir un appareil de nettoyage dans lequel du liquide est acheminé de la chambre à liquide jusqu'à la surface du corps creux uniquement dans certaines conditions. A cette fin, un élément formant valve (6), fonctionnant de manière autonome en fonction de la force appliquée, est associé à l'ouverture (5), l'élément formant valve pouvant se déplacer, en fonction de la quantité de force centrifuge agissant sur ledit élément en raison de la rotation du rouleau de nettoyage (2), dans une position de fermeture qui ferme l'ouverture (5) du corps creux et/ou dans une position d'ouverture qui libère ladite ouverture (5). L'élément formant valve (6) est conçu pour laisser sortir du liquide de la chambre à liquide (4) lorsque le rouleau de nettoyage (2) tourne à une première vitesse (n1), et pour bloquer la sortie de liquide, lorsque la vitesse de rotation croissante atteint une seconde vitesse (n2) supérieure à la première vitesse (n1).
