Abstract

L'invention concerne un dispositif de nettoyage pour nettoyer des objets. Ce dispositif comprend une section de nettoyage à la vapeur et une section de génération de vapeur qui sont prévues dans une seule cuve de nettoyage pour assurer un traitement de nettoyage à la vapeur et un traitement de séchage. La communication entre les ces deux sections est assurée ou coupée par un couvercle d'étanchéité mobile dans le sens vertical. L'invention permet d'obtenir un dispositif de nettoyage compact économique. La section de nettoyage à la vapeur (3) pour nettoyer et sécher les objets est placée dans la zone supérieure et est remplie d'un liquide de nettoyage (7). La section de génération de vapeur (4) prévue pour vaporiser le liquide de nettoyage (7) est placée dans la zone inférieure, constituant une cuve de nettoyage (1). La communication entre la zone de nettoyage à la vapeur (3) et la section de génération de vapeur (4) est assurée par un orifice de communication (10). Cet orifice est placé de telle sorte qu'il est peut être fermé ou ouvert par le couvercle mobile dans le sens vertical (11).
