Abstract
A spring-loaded filter assembly for a liquid dispenser is disclosed that permits ready removal of a filter element from a filter housing. The filter assembly includes the filter housing having a liquid inlet, a liquid outlet, and a liquid passageway between the inlet and outlet. An opening is affixed to the filter housing and is removably closed by a closure element. A filter element is positioned for movement within the filter housing between a filtering position and an access position. According to the present invention, a biasing member is positioned in the filter housing. When the closure element is removed from the opening, the biasing member is configured for urging the filter element from the filtering position to the access position for removing the filter element from the filter housing.
