摘要： A filter cartridge for a household appliance, which is provided with a filter housing, the wall of which separates a housing internal side from a housing external side. A filter inlet opening which in the operation of the filter cartridge is open in relation to the external environment of the filter housing. A device for water conduction which comprises at least one filter chamber having at least one filter medium and terminates in a filter outlet opening for suctioning water from the filter cartridge in the interior of the filter housing downstream of the filter inlet opening relative to the flow direction during operation. A filter connection element having an annular filter port which has an annular filter sealing face for the tight connection of the filter cartridge to a tank sealing face in the water tank.

摘要： A filter cartridge for use in the interior of a water tank of a household appliance, the wall of which separates a housing internal side from a housing external side. A filter inlet opening which in the operation of the filter cartridge is open in relation to the external environment of a filter housing. A device for water conduction comprises at least one filter chamber having at least one filter medium and terminates in a filter outlet opening for suctioning water from the filter cartridge in the interior of the filter housing, downstream of the filter inlet opening relative to the flow direction of the water during operation. A filter port has an annular filter sealing face for the connection of the filter cartridge in a water tank. The filter sealing face has a separately disposed filter-proximal guide structure for receiving a centering element for centering the filter cartridge.
