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
A water-filter device having one or more filter sections for treating water, in particular by ion exchange, and having an adjusting mechanism for setting a mixing ratio between water treated by the filter section and water which is guided past the filter section via a bypass section and is not treated or is treated in some other way, characterized 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).
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting medium (5) can be changed in dependence on a physical and/or chemical property of the liquid which has flowed through it.
The water-filter device as claimed in one of the preceding claims, characterized by the provision of a liquid-soluble adjusting medium (5).
The water-filter device as claimed in one of the preceding claims, characterized by the provision of a shrinkable adjusting medium (5).
The water-filter device as claimed in one of the preceding claims, characterized by the provision of an adjusting medium (5) which expands and/or is capable of swelling.
The water-filter device as claimed in one of the preceding claims, characterized by the provision of a food-compatible adjusting medium.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting medium is suitable as a health-promoting nutritional supplement and/or as a food supplement and/or as a drinking-water additive.
The water-filter device as claimed in one of the preceding claims, characterized in that vitamin C, limestone and dolomite rock, flavorings, food base materials, siliphosphate, phosphate combinations or polyphosphate are provided as the adjusting medium.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting medium is provided in the form of a powder, granules, crystals or compact.
The water-filter device as claimed in one of the preceding claims, characterized by the provision of different three-dimensionally geometrical structures of the adjusting medium.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting medium is provided in the form of an ion-exchange resin.
The water-filter device as claimed in one of the preceding claims, characterized by the provision of different adjusting media.
The water-filter device as claimed in one of the preceding claims, characterized in that a body (10) formed from the adjusting medium (5) is designed in the form of a closing element.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting medium (5) is provided for actuating a closing element (10) and/or opening element (10).
The water-filter device as claimed in one of the preceding claims, characterized by the provision of a restoring element (24).
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting mechanism (1) is arranged on an inflow (23) and/or on an outflow (24) of the filter device (20).
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting mechanism (1) is provided for controlling a liquid stream (7) in a filter device (20).
The water-filter device as claimed in one of the preceding claims, characterized by the provision of continuous adjustment of the mixing ratio.
The water-filter device as claimed in one of the preceding claims, characterized by the provision of threshold-value-dependent adjustment of the mixing ratio.
The water-filter device as claimed in one of the preceding claims, characterized in that the restoring element (24) is provided for closing and/or opening the mixing device.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting medium (5) is provided for opening and/or closing the mixing device (26) counter to the restoring force of the restoring element (34).
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting mechanism is designed such that, at least during an initializing operation of the water-filter device and/or following the same, it sets a mixing ratio which is dependent on the quality of the water which is to be filtered and/or on the respective application.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting mechanism is designed such that it changes the mixing ratio during operation of the water-filter device.
The water-filter device as claimed in one of the preceding claims, characterized in that a substance which is to be filtered out of the water-filter device is provided as the adjusting medium.
The water-filter device as claimed in one of the preceding claims, characterized by the provision of at least one further adjusting mechanism.
The water-filter device as claimed in one of the preceding claims, characterized by the provision of a means for indicating the degree to which the filter medium has been depleted.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting mechanism (1) is a valve.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting mechanism (1) is a control valve.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting mechanism (1) is a pilot valve.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting mechanism is assigned to a filter cartridge of the filter device.
The water-filter device as claimed in one of the preceding claims, characterized in that the adjusting mechanism is assigned to a connection element for a filter cartridge of the filter device.
