Water Filter Patent
 

Hinge down refrigerator water filter

A refrigerator water filter assembly is provided in the ceiling of a refrigerator and is adapted to hinge downwardly from the ceiling for changing the filter cartridge. The cartridge is normally partially recessed within the ceiling so as to minimize the use of space in the food compartment of the refrigerator. The filter assembly includes a base mounted in the refrigerator ceiling, a manifold pivotally mounted on the base, a filter cartridge attached to the manifold, and a cover pivotally mounted on the manifold so as to be movable between open and closed positions. When the cover is opened, the filter cartridge is angled downwardly from the ceiling for easy grasping by a person for replacement of the cartridge.

Water filter vacuum cleaner

An improved water filter vacuum cleaner includes a vacuum body which contains a dust chamber and a dust collector assembly in the dust chamber that contains filter water. The dust collection assembly includes a dust collection seat and an upper cap. The dust collection seat is divided by a partition to form a filter chamber and an airflow chamber that communicate with each other. The airflow chamber has an airflow duct connecting to the filter chamber. The vacuum body has a suction assembly to generate a suction airflow which sucks suction articles through the airflow duct into the filter chamber. The suction airflow generates oscillating moisture to trap the suction articles. The cleaned suction airflow passes through the upper cap and a guiding member communicating with the upper cap to the suction assembly to form output airflow in the suction assembly to be discharged through an air outlet.

Water filter for an electrochemical fuel cell system

Silica may form as a degradation product in an electrochemical fuel cell system and may be found within the water management subsystem thereof. The silica may polymerize and/or react to form insoluble metal silicates which may lead to reduced lifetime or performance of individual components within the fuel cell system. These problems can be eliminated or reduced by adding a silica absorber such as aluminum, either as alumina granulate or an aluminum plate to the water management subsystem, for example in, upstream and/or downstream of the water filter. In addition, the silica absorber may be in, upstream and/or downstream of the water tank.

Water filter cartridge comprising an exchangeable testing unit that contains a conductance sensor

A water filter cartridge is proposed that is intended especially for treating drinking water in beverage machines or drinking water devices, which includes a replaceable control unit to monitor the condition of the water filter cartridge (1). The water filter cartridge according to the invention is intended to make possible reliable monitoring of its condition. This is accomplished according to the invention in that the control unit includes a sensor unit (11) with at least one conductance sensor (13 14).
