A reverse coffee extraction device according to an embodiment includes a pump configured to pump water upwards; and a brewing container installed above the pump to extract coffee, wherein the water pumped upwards is delivered to the brewing container and moves upwards, and the coffee in the brewing container is brewed and extracted to an outside while the water supplied down moves up.

The water-dispensing system with coffee maker comprises a water generation system, a condensate pump, a condensate filter, and a coffee maker. The coffee maker further comprises a water storage reservoir and a power circuit. The water generation system, the condensate pump, and the condensate filter are fluidically connected. The condensate filter fluidically connects to the water storage reservoir of the coffee maker. The water generation system and the condensate pump electrically connect to the power circuit. The water-dispensing system with coffee maker is powered using electrical energy provided by a power circuit provisioned through the coffee maker.

A water tank for a household appliance having a connection for a filter cartridge, wherein an annular tank sealing face is provided on the tank bottom for the tight connection of the filter cartridge and the tank sealing face encloses a tank passage opening for the water from the filter cartridge to flow through the wall of the tank bottom to the household appliance, characterized in that the tank sealing face along its circumference has a variable radius in relation to a central axis, so that the tank sealing face comprises radial concavities and/or radial convexities, wherein the convexities and/or concavities have a round profile, and wherein the concavities and/or convexities are configured to periodically oscillate around a circular line.

A beverage preparation device comprising a main body, a tank, an assembly for pumping a liquid from the tank, and a unit for preparing the beverage, in which device an outlet path is defined inside the main body, the outlet path comprising a dispensing outlet, via which the beverage is dispensed out of the main body, and also comprising a filtering element that is detachably connected to the main body, wherein the filtering element is arranged downstream of the dispensing outlet relative to the outlet path.

Exemplary embodiments of a filter cartridge for a coffee machine are disclosed. According to one exemplary embodiment, a coffee machine filter cartridge may include a filter body having a water inlet, a grate and a water outlet, and a lid held on the filter body. The water inlet is disposed around the water outlet. The water outlet connects to one end of the grate through a pipe. The other end of the grate is held on the inner wall of the filter body and comprises a cloth filter. A filter chamber between the pipe and the filter body has a descaling core. When filtering and descaling, the water flows sequentially through the water inlet, filter chamber, grate, cloth filter, pipe, and water outlet. The cartridge is structurally simple, convenient and accessible to users; preventing clogging of the internal parts of the coffee machine by slow dissolution of the descaling agent.
