摘要

The tank for aquiferous household appliances or beverage dispensers, coffee dispensers, drinking water dispensers, cooking and baking devices, steam irons, steam cleaners, high-pressure cleaners, air pressure cleaners and/or conditioners, comprises a filter connector equipped with an axial projection and/or axial recess having radial coding structures to which a filter cartridge is adapted according to a key/lock principle, a sealing surface (24) for a filter side axial sealing, and a circumferential area intended as a sealing surface at the tank side filter connector element. The tank for aquiferous household appliances or beverage dispensers, coffee dispensers, drinking water dispensers, cooking and baking devices, steam irons, steam cleaners, high-pressure cleaners, air pressure cleaners and/or conditioners, comprises a filter connector equipped with an axial projection and/or axial recess having radial coding structures to which a filter cartridge is adapted according to a key/lock principle, a sealing surface (24) for a filter side axial sealing, a circumferential area intended as a sealing surface at the tank side filter connector element, a locking intended between the filter cartridge and the filter connector element, a blending section intended for blending filtered water with unfiltered and/or other recycled water, a sealing intended between the filter connector element and tank connector element, an opening with coding structure for introducing a filter side key element at the tank base (29), and an adapter for the connection of the filter cartridge and the aquiferous device at the filter connector element. The filter connector of the water tank and a connection support of the filter cartridge partially surround with one another. The inserted filter cartridge extends itself to the coding structure in axial and/or radial direction oriented to the axis of the connection support. The sealing has a partially round cross section. The coding structures are partially formed as fixing element for fixing the filter cartridge. The coding is provided through the amount and/or spatial distribution and/or form of single coding element of the coding structure, which is provided at the circumference of the tank side filter connector element, which has a circumferential form with rotationally symmetrical cross section with 4, 6 and/or 8 edges. The filter side connector element is formed as a coding structure and as form sealing with circumferential area. The coding structure is externally arranged at the housing of the filter cartridge in incorporated condition. Independent claims are included for: (1) aquiferous household device or devices for the processing of food and/or beverages; and (2) a filter cartridge for the tank.
