Title
(EN) ASSEMBLY OF A DRAIN WITH AN AERATOR TO INCREASE THE RELIABILITY OF AN OVERFLOW MECHANISM
(FR) ENSEMBLE D'UN DRAIN DOTÉ D'UN AÉRATEUR POUR AUGMENTER LA FIABILITÉ D'UN MÉCANISME DE TROP-PLEIN
Abstract
(EN)
An assembly comprising a drain (1) for sanitary fixtures provided with an overflow mechanism, and of a respective aerator (100), is described. The aerator (100) comprises a body (101) delimiting a housing (102) opened on top and on the bottom that can be crossed by a flow of water, in which the drain (1) for sanitary fixtures provided with an overflow mechanism is inserted. The aerator (100) comprises a channel (105) fluidically connecting a lower portion of the housing (102) with the outside, and a floating element (104, housed in the channel (105), movable between an inactive position and an active position. In the active position, the floating element (104) sealingly intercepts the channel (105) itself, and prevents the rising and spillage of water through the channel (105). In the inactive position, the floating element does not intercept the channel (105) or it only partly intercepts it, and the channel (105) can be crossed by a flow of air that enters the channel (105) and that is inserted in the housing (102) where the drain (1) is located, so that to aerate and stabilize the flow of water being drained.
(FR)
L'invention concerne un ensemble comprenant un drain (1) pour des appareils sanitaires pourvus d'un mécanisme de trop-plein, et d'un aérateur respectif (100). L'aérateur (100) comprend un corps (101) délimitant un logement (102) ouvert sur le dessus et sur le fond qui peut être traversé par un écoulement d'eau, dans lequel le drain (1) pour des appareils sanitaires munis d'un mécanisme de trop-plein est inséré. L'aérateur (100) comprend un canal (105) reliant de manière fluidique une partie inférieure du logement (102) à l'extérieur, et un élément flottant (104), logé dans le canal (105), mobile entre une position inactive et une position active. Dans la position active, l'élément flottant (104) intercepte de manière étanche le canal (105) lui-même, et empêche l'élévation et le déversement d'eau à travers le canal (105). Dans la position inactive, l'élément flottant n'intercepte pas le canal (105) ou l'intercepte uniquement en partie, et le canal (105) peut être traversé par un écoulement d'air qui entre dans le canal (105) et qui est introduit dans le logement (102) où le drain (1) est situé, de sorte à aérer et à stabiliser l'écoulement d'eau qui est drainé.
