The invention relates to a water tank () and a water filter cartridge () where the water filter cartridge () has two different water filter cartridge outlets connected to two different filter treatment sections in a single filter cartridge housing to provide for the different treatment of water received from a common inlet. More particularly, the new filter can treat hot water separately from cold water and discharge the separately treated water from the which can be arranged concentrically to one another.

Water tank with tank outlet valve and water filter cartridge with two water filter cartridge outlets which are arranged concentrically to one another

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 (), 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.

Water filter cartridge having tank limescale protection

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 flow and the dosing flow and causes a volumetric flow rate of the dosing flow of salt solution which is substantially proportional to the main flow, through the dosing opening into the main flow.

Mineralization cartridge and method for the operation thereof

The present invention relates to a water filter cartridge, with a housing and a flow path for air for ventilating a water tank storing water to be processed by the water filter cartridge. The latter is distinguished in that the flow path has a first water barrier.

Water filter cartridge with air conduction

The present invention relates to a water filter cartridge, with a housing and a flow path for air for ventilating a water tank storing water to be processed by the water filter cartridge. The latter is distinguished in that shut-off means are provided for the flow path for air, preferably in the form of a valve or a membrane.

The present invention relates to a water treatment apparatus (), in particular for supplying water-conducting and/or water-heating household appliances or appliances for producing and preparing food and/or beverages using treated drinking water, e.g. automatic drinks machines, automatic coffee machines, ice machines, cooking and baking appliances, steam generators or high-pressure cleaners, air conditioners or the like using treated water, comprising an agent () present in solid form for reducing mineral precipitates. It is characterized in that a first medium which influences the dissolution behavior of the agent for reducing mineral precipitates is provided.

Water conditioner for preventing or reducing mineral precipitation

The present invention relates to a beverage machine, more particularly for preparing hot drinks, with a liquid cleaner replaceable container formed as a replaceable container, characterized in that parts of a liquid cleaner dosing device are formed interchangeable with the liquid cleaner replaceable container.

Cleaning dispenser

A tank is proposed for appliances which use water, in particular domestic appliances or appliances for preparation of foodstuffs and/or drinks, such as automatic drinks machines, in particular automatic coffee machines, drinking water dispensers, cooking and baking appliances, steam appliances, in particular steam irons, steam cleaners, high-pressure cleaners, air cleaners and conditioners or the like, with a connection being provided on the tank for supplying water from the tank to the appliance and with a filter connection being provided for connection of a filter cartridge in the interior and/or outside the tank, while providing assurance that only the permitted filter type can be used. A tank according to the invention is distinguished by mechanical coding structures on the filter connecting element, in order to preclude the use of a filter cartridge which does not correspond to the tank.
