A filter structure comprises a filtering member, a housing, and an upper supporter. The housing comprises a housing body comprising an opening portion and a housing cap coupled to the opening portion of the housing body. The upper supporter is coupled to the filtering member and disposed on an inner surface of the housing cap. The upper supporter comprises a supporter extending portion extending from the upper supporter portion, the supporter extending portion comprises a filter inlet flow path, a projection portion formed on an inner surface of the filter inlet flow path, and a filter outlet flow path separated from the first filter inlet flow path in the supporter extending portion.

Provided are a water purifying apparatus and a refrigerator including the same. The water purifying apparatus includes a filter configured to purify incoming water and discharge the purified water, a head in which the filter is detachably coupled and a water inlet portion and a water outlet portion are formed, and a shaft provided inside the head and rotatably mounted between the water inlet portion and the water outlet portion, the shaft being provided with a bypass flow path directly connecting the water inlet portion and the water outlet portion and a filtering flow path connected so that water flowing in through the water inlet portion is discharged to the water outlet portion via the filter.

A water filter cartridge assembly for fluid filtration which may be attached to, and removed from an appliance water filter manifold assembly of an appliance, typically by a push-actuated release. The water filter cartridge assembly has a filter housing, and an ingress port and egress port extending therefrom. Each of the ingress port and the egress port typically comprise a port portion having a varying radial diameter. The water filter cartridge assembly further comprises a connection assembly that is structured to establish an electrical connection between the connection assembly and a controller of the appliance. Both of said ingress and egress port have at least one aperture for the passage of fluid therethrough such that each of the at least one aperture is exposed in a direction facing away from the connection assembly.

A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a filter key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter housing assembly may be attached to, and removed from, a filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

A refrigerator including a cabinet and a compartment formed inside the cabinet and having an open front portion. A compartment door is movably connected to the cabinet for closing at least partially the open front portion of the compartment. An ice maker assembly is arranged inside the compartment and includes an ice maker. The ice maker includes an ice maker casing, a water tank and a water filter. The ice maker assembly is accessible inside the compartment when the compartment door is in an open position. The ice maker assembly includes a support housing arranged below the ice maker casing to receive the water tank and the water filter such that the ice maker casing and the support housing are provided as respective modules.

A refrigerator includes a main body that defines a storage space, a door configured to open or close the storage space, and a dispenser located in the door and configured to dispense cooled water and purified water. The refrigerator also includes a purified water input part that inputs a command for dispensing the purified water, a cooled water input part that inputs a command for dispensing the cooled water, and a dispensing amount input part that sets an amount of purified water to be dispensed based on the purified water being selected through the purified water input part. The refrigerator further includes a filter device located within the storage space to purify water supplied from a water supply source, and a water tank storing water that has passed through the filter device in a cooled state.

A reverse osmosis filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with the raw water ingress, permeate egress, and reject water egress. The reverse osmosis filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

A water purifying filter has a cylindrical inner housing to receive a filter therein, and an outer housing to receive the inner housing. The inner housing and the outer housing are spaced apart from each other to form an insulation space configured to suppress heat transfer and to reduce the filter freezing inside the inner housing.

A water filter cartridge assembly for fluid filtration which may be attached to, and removed from an appliance water filter manifold assembly of an appliance, typically by a push-actuated release. The water filter cartridge assembly has a filter housing, and an ingress port and egress port extending therefrom. Each of the ingress port and the egress port typically comprise a port portion having a varying radial diameter. The water filter cartridge assembly further comprises a connection assembly that is structured to establish an electrical connection between the connection assembly and a controller of the appliance. Both of said ingress and egress port have at least one aperture for the passage of fluid therethrough such that each of the at least one aperture is exposed in a direction facing away from the connection assembly.

A refrigerator including a main body having a storeroom, an inner door rotatably coupled to the main body and having a door opening, an outer door rotatably arranged in front of the inner door to open or close the door opening, a dispenser including a water-intake space and an operation lever and configured to supply water to the water-intake space by manipulation of the operation lever, and an automatic water supplier including a water container installation space formed to have a water container mounted and a water level sensor configured to detect a water level of the water container, and configured to supply water into the water container to fill the water container with a certain amount of water. The water-intake space and the water container installation space may be arranged in the door opening of the inner door to be accessed while the inner door is closed.
