Abstract

A water filter device includes a container ( 1 ) that has an opening for filling of water, and a filter unit ( 3 ) that is movable relative to the container ( 1 ). It is significant of the device that the filter unit ( 3 ) includes a filter element ( 5 ), an operating rod ( 7 ) connected to the filter element ( 5 ) and sealing means ( 14 ) along the periphery of the filter element ( 5 ), and that the filter element ( 5 ) has a particle filter ( 10 ) and an adsorption filter ( 11 ).

Claims (7)

1. Water filter device, said device comprising a container ( 1 ; 101 ) that has an opening for filling of water, and a filter unit ( 3 ; 103 ) that is movable relative to the container ( 1 ; 101 ), the filter unit ( 3 ; 103 ) comprising a filter element ( 5 ; 105 ), an operating rod ( 7 ; 107 ) connected to the filter element ( 5 ; 105 ) and sealing means ( 14 ; 116 ) along the periphery of the filter element ( 5 ; 105 ), the filter element ( 5 ; 105 ) comprising a particle filter ( 10 ; 110 ) and an adsorption filter ( 11 ; 111 ), the operating rod ( 7 ; 107 ) being coated with an agent that emits silver ions.

2. Device according to claim 1 , characterized in that the filter element ( 5 ; 105 ) generally is disc shaped, and that the operating rod ( 7 ; 107 ) generally extends perpendicular to the filter element ( 5 ; 105 ).

3. Device according to claim 1 , characterized in that the filter material in the particle filter ( 10 ; 110 ) constitutes polypropylene.

4. Device according to claim 1 , characterized in that the filter material in the adsorption filter ( 11 ; 111 ) constitutes active carbon.

5. Device according to claim 1 , characterized in that a partition ( 118 ) is provided in the adsorption filter ( 111 ), said partition ( 118 ) extending transverse to the longitudinal direction of the operating rod ( 107 ).

6. Device according to claim 5 , characterized in that the partition is in the shape of a circular disc ( 118 ) with a smaller diameter than the filter element ( 105 )

7. Device according to claim 1 , characterized in that the sealing means ( 14 ; 114 ) comprises a tongue ( 16 ; 116 ), whose free end in active position abuts the inner side of the container ( 1 ; 101 ).
