  • Patent number: 11827531
    Abstract: A water filter system has a housing with the channel formed adjacent a bottom thereof and at least one chamber formed therein, and at least one filter removably received in the chamber. The channel is adapted to connect with a water inlet line. The channel is also adapted to connect with a water outlet line. The filter is in communication with the channel at a bottom thereof. The filter and an inner wall of the chamber define an annulus therebetween. The filter has an interior passageway that opens to a filter media. The filter media is disposed such that water flows from the channel and into the interior passageway, through the filter media, and into the annulus. The annulus then communicates with the channel.

  • Patent number: 11819156
    Abstract: 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.
