Abstract
The present invention relates to a water-filter device. This is distinguished by the provision of an adjusting medium (5) of which the volume and/or the structure change/changes by way of a liquid (6) which is in contact with the adjusting mechanism (1) and/or has flowed through the adjusting mechanism (1).
Claims40
In a drinking water-filter device having one or more filter sections for treating drinking water, and having an adjusting mechanism for setting a mixing ratio between drinking water treated by the filter section and drinking water which is guided past the filter section via a bypass wherein the improvement comprises an ion exchange device for treating drinking water or a filter medium in at least one filter section for treating drinking water and an autonomous adjusting medium in which the volume and/or the structure of the autonomous adjusting medium change or changes by way of a liquid (6) which is in contact with the autonomous adjusting medium (5) and/or has flowed through the autonomous adjusting medium which forms an adjustable bypass closure element disposed in the bypass, wherein said adjustable bypass closure element is opened or closed by said autonomous adjusting medium.
A water tank with an insertable drinking water filter cartridge comprising:
- (a) a water tank with an outlet;
- (b) an insertable drinking water filter cartridge with a bypass, the insertable drinking water filter cartridge having one or more filter sections or at least one section for treating drinking water by ion exchange;
- (c) an adjustable bypass flow orifice disposed in the bypass for setting a mixing ratio between drinking water treated by a filter section and drinking water which is guided past the filter section via the bypass;
- and
- (d) an autonomous adjusting medium activated by a volume or a structure change resulting from a liquid in contact with or that has flowed through the autonomous adjusting medium to adjust the adjustable bypass flow orifice disposed in the bypass.
An appliance (51) with a filter head comprising:
- (a) a filter head adapted to accept a drinking water filter insert;
- (b) a drinking water filter insert with a bypass, the drinking water filter insert having one or more filter sections for treating drinking water with at least one filter or ion exchange section for treating drinking water;
- (c) an adjustable autonomously controlled valve disposed in the bypass to set a mixing ratio between drinking water treated by a filter section and water which is guided past a filter section;
- and
- (d) an autonomous adjusting medium activated by a change in volume or structure resulting from a liquid in contact with the autonomous adjusting medium or liquid that has flowed through the autonomous adjusting medium which autonomously controls the adjustable autonomously controlled valve and changes a flow volume through the bypass by operation of the adjustable autonomously controlled valve disposed in the bypass.
