Title
(DE) WASSERTANK MIT FILTERPATRONE
(EN) WATER TANK WITH FILTER CARTRIDGE
(FR) RÉSERVOIR D'EAU DOTÉ D'UNE CARTOUCHE FILTRANTE
Abstract
(DE) Die Erfindung betrifft einen Wassertank (1) für eine Haushaltsmaschine mit einem Anschluss für eine Filterpatrone, wobei an dem Tankboden eine ringförmige Tankdichtfläche zum dichten Anschluss der Filterpatrone vorgesehen ist und die Tankdichtfläche eine Tankdurchgangsöffnung zum Durchfluss des Wassers aus der Filterpatrone durch die Wandung des Tankbodens zur Haushaltsmaschine umschließt. Der Wassertank zeichnet sich dadurch aus, dass die Tankdichtfläche entlang ihrem Umfang einen variierenden Radius gegenüber einer zentralen Achse aufweist, so dass die Tankdichtfläche radiale Einbuchtungen und/oder radiale Ausbuchtungen umfasst, wobei die Ausbuchtungen und/oder Einbuchtungen einen runden Verlauf aufweisen.
(EN) The invention relates to a water tank (1) for a domestic appliance, comprising a connection for a filter cartridge, wherein an annular tank sealing surface for tight connection of the filter cartridge is provided on the tank bottom and the tank sealing surface surrounds a tank through-opening for the flow of the water from the filter cartridge through the wall of the tank bottom to the domestic appliance. The water tank is characterized in that the tank sealing surface has, along its periphery, a varying radius with respect to a central axis, such that the tank sealing surface has radial recesses and/or radial bulges, the bulges and/or recesses having a round profile.
(FR) L'invention concerne un réservoir d'eau (1) pour un appareil électroménager, comprenant un raccord pour une cartouche filtrante, une surface d'étanchéité de réservoir annulaire pour un raccordement étanche de la cartouche filtrante étant disposée sur le fond de réservoir et la surface d'étanchéité de réservoir entourant une ouverture de passage de réservoir pour l'écoulement de l'eau de la cartouche filtrante à l'appareil domestique, à travers la paroi du fond de réservoir. Le réservoir d'eau est caractérisé en ce que la surface d'étanchéité de réservoir présente, le long de sa périphérie, un rayon variable par rapport à un axe central, de telle sorte que la surface d'étanchéité du réservoir présente des évidements radiaux et/ou des renflements radiaux, les renflements et/ou les évidements ayant un profil arrondi.
