Title
(DE) FILTERVORRICHTUNG ZUR TRINKWASSERFILTERUNG
(EN) FILTER DEVICE FOR FILTERING DRINKING WATER
(FR) DISPOSITIF DE FILTRATION D’EAU POTABLE
Abstract
(DE)
Die Erfindung betrifft eine Filtervorrichtung (1) zur Trinkwasserfilterung, mit einer Anschlussvorrichtung (2), an der ein Aufnahmeteil (10) zum Anschluss einer Filterkartusche (20) schwenkbar gelagert ist, wobei das Aufnahmeteil (10) eine zumindest abschnittsweise rotationssymmetrisch geformte Wandung (13) aufweist,welche eine konvexe Gleitfläche bildet, an der zu einem in dem Aufnahmeteil (10) ausgebildeten Filteranschluss führende Zulauf-und Rücklaufkanäle (16, 17) für das zu filternde Trinkwasser münden, wobei die Wandung (13) gegen eine zumindest abschnittsweise zu dieser koaxial gekrümmten Innenwand (9) der Anschlussvorrichtung (2) dichtend anliegt und an der Innenwand (9) Anschlussöffnungen (3, 4) für einen Zulauf und Rücklauf des zu filternden Trinkwassers münden, und wobei das Aufnahmeteil (10) in eine Arbeitsposition (A), in welcher die Mündungen (18) der Zulauf-und Rücklaufkanäle (16, 17) dichtend über den zugehörigen Anschlussöffnungen (3, 4) in der Innenwand (9) der Anschlussvorrichtung (2) liegen, schwenkbar ist sowie in eine Wechselposition (B), in welcher die Filterkartusche (20) von dem Aufnahmeteil (10) abnehmbar bzw. in eine Anschlussöffnung des Filteranschlusses im Aufnahmeteil (10) einführbar ist und die Wandung (13) des Aufnahmeteils (10) zumindest die Anschlussöffnungen (3, 4) für den Zulauf und Ablauf des zu filternden Trinkwasser dichtend verschließt.
(EN)
The invention relates to a filter device (1) for filtering drinking water, having a connection device (2), on which a receiving part (10) for connection of a filter cartridge (20) is pivotably mounted, the receiving part (10) having a wall (13) that is rotationally symmetrical at least in sections and that forms a convex sliding surfface at which feed and return channels (16, 17) for the drinking water to be filtered open out into a filter connection formed in the receiving part (10), the wall (13) bearing sealingly against an inner wall (9) of the connection device (2), which inner wall is curved coaxially relative to said wall at least in some sections, and connection openings (3, 4) for a feed and return of the drinking water to be filtered opening out at the inner wall (9), and the receiving part (10) being pivotable into a working position (A), in which the mouths (18) of the feed and return channels (16, 17) lie sealingly over the associated connection openings (3, 4) in the inner wall (9) of the connection device (2), and into an exchange position (B), in which the filter cartridge (20) is removable from the receiving part (10) or is insertable into a connection opening of the filter connection in the receiving part (10), and the wall (13) of the receiving part (10) sealingly closes at least the connection openings (3, 4) for the feed and discharge of the drinking water to be filtered.

L’invention concerne un dispositif de filtration (1) d’eau potable, comportant un dispositif de raccordement (2) sur lequel est monté pivotant un élément de logement (10) servant au raccordement d’une cartouche filtrante (20), l’élément de logement (10) présentant une paroi (13) au moins sur une partie de forme symétrique en rotation, laquelle forme une surface de glissement convexe au niveau de laquelle débouchent des canaux d’arrivée et de retour (16, 17) de l’eau potable à filtrer conduisant à un raccordement de filtre formé dans l’élément de logement (10). La paroi (13) porte hermétiquement contre une paroi intérieure (9), incurvée au moins sur une partie par rapport à celle-ci, du dispositif de raccordement (2). Des ouvertures de raccordement (3, 4) pour une arrivée et un retour de l’eau potable à filtrer débouchent au niveau de la paroi intérieure (9) et, dans une position de travail (A) dans laquelle les embouchures (18) des canaux d’arrivée et de retour (16, 17) sont placés hermétiquement sur les ouvertures de raccordement (3, 4) dans la paroi intérieure (9) du dispositif de raccordement (2), l’élément de logement (10) peut être pivoté et, dans une position inverse (B) dans laquelle la cartouche filtrante (20) peut être enlevée de l’élément de logement (10) ou introduite dans une ouverture de raccordement du raccordement de filtre dans l’élément de logement (10), la paroi (13) de l’élément de logement (10) ferme hermétiquement au moins les ouvertures de raccordement (3, 4) pour l’arrivée et le retour de l’eau potable à filtrer.
