A water filter assembly is provided that includes features that facilitate mounting and removal of a water filter cartridge to and from a manifold. In particular, the water filter assembly includes an electromagnet interface that simplifies and aids mounting of the water filter cartridge to the manifold as well as removal therefrom.

A method of applying a hydrophobic surface coating to one or more internal surfaces of a fluid passage component, the method including: flowing a rare earth precursor into the fluid passage component; allowing the rare earth precursor to react with the one or more internal surfaces of the fluid passage component; removing excess rare earth precursor from the fluid passage component; flowing an oxide forming precursor into the fluid passage component; allowing the oxide forming precursor to react with the rare earth precursors on the one or more internal surfaces to form a hydrophobic surface coating on each of the one or more internal surfaces; and removing excess oxide forming precursor from the fluid passage component.

Included are systems, methods and devices for cooling beverages, comprising an upper insulated basin sized to allow placement of cooling fluid and beverage containers; a separator device sized to restrain the beverage containers such that during agitation, each of the beverage containers does not impact any other of the beverage containers or the side surface of the upper insulated basin and allows for cooling fluid to contact an exterior surface of each of the beverage containers; and an agitation section placeable in physical communication with the upper basin that can provide, when activated, motion to the upper insulated basin.

According to an embodiment of the present invention, there is provided a refrigerator including: a cabinet which has a storage chamber therein; an inner door which is rotatably connected to a front surface of the cabinet, opens and closes a portion of the storage chamber, and has an access hole of a predetermined size; an accommodation case which is mounted on a rear surface or the inner door, and has a front surface which is opened so as to communicate with the access hole and a rear surface which has a plurality of cool air holes which are vertically spaced apart from each other; an outer door which is rotatably connected to the inner door at a front side of the inner door and selectively opens and closes the access hole; a shielder which is movably coupled to the rear surface of the accommodation case to selectively shield the plurality of cool air holes; and a driver which is provided in the accommodation case for vertically moving the shielder.

A household cooling appliance includes an outer housing, a cooling compartment in the outer housing, and an ice maker unit, which is arranged in the cooling compartment. The ice maker unit includes a first sub-unit, which is configured for making crushed ice from ice form elements. The first sub-unit has a housing. A crusher device for crushing the ice form element is arranged in the housing. A cooling device cools the first sub-unit with cold air. The cooling device has an air duct. The air duct ends at the housing of the first sub-unit and at least partly is configured to extend along an outer side of the housing so that the cold air for cooling the housing flows along the outer side of the housing.
