  • Patent number: 12195353
    Abstract: The invention relates to a water filter cartridge comprising a housing and a filter-side tank connection element for insertion into a water tank, more particularly into a water tank of a household appliance (11), and a filter section for treating the water to be taken from the water tank. It is distinguished by the fact that the water filter cartridge comprises a reservoir chamber with a means to counter precipitations in the water tank, where the reservoir chamber is designed separate from the filter section and its flow guideway for the water running through the filter section to be treated, in such a way that there is no contact between the water flowing through the filter section and the means to counter precipitations, and that the reservoir chamber has at least one passage for the means, whereby the means to counter precipitations is in contact with the unfiltered water in the water tank.

  • Patent number: 12017936
    Abstract: The invention relates to a method for operating a water filter cartridge in a pipe, said water filter cartridge having a housing in the form of a pressure vessel, and an inlet and an outlet for water, characterized in that a main flow of water to which minerals are added is conducted through a main pipe inside the pressure vessel, and a dosing flow of concentrated salt solution is conducted through a dosing pipe, wherein the dosing pipe branches off from the main pipe and passes through a reservoir of constant volume and in which there is a concentrated salt solution consisting of sulphate salt, chloride salt and/or hydrogen carbonate salt, wherein the part of the dosing pipe extending from the reservoir leads into the main flow at a dosing point through a dosing opening with a constant flow cross-section, and wherein a resistance section which is situated upstream of the dosing point in the main flow is used to set the flow resistance in the main flow such that a pressure difference results between the main
