An air filter apparatus includes a filter body mountable in a support surface. A filter insert is mounted in a bore extending from one end of the body. A labyrinth air flow path is formed between a portion of the exterior surface of the filter body and an end cap mounted over an end portion of the body and through the filter insert in the bore in the body to prevent the ingestion of fluid through the filter.

A refrigerator freezer door has an ice service area in its outer face including an actuator for opening a passage closure member. Upon depressing the actuator a switch is closed to energize a power driven ice dispenser in the freezer compartment which discharges ice pieces down a chute and into the passage through the freezer door to the service area. A suction cup positioned on the actuator has an air bleed passageway to delay return movement of the actuator and closing of the closure member until the chute has emptied its ice pieces into the passageway.

Ice door delay mechanism

A vertical sliding closure panel assembly for an appliance such as a refrigerator cabinet for closing a service area located on a food compartment door. The sliding closure panel has its edges formed with inwardly offset integral flanges defining vertical channels for reception of return flanges formed on the frame portions of the assembly providing passageways for the channels. The sliding panel has resilient clip members positioned on its side flanges operative to impart positioning stability so that the panel can be retained at any location between its fully open and fully closed position.

A refrigerator cabinet water storage tank is oriented horizontally on the floor of the fresh food compartment and includes first and second side-by-side water storage chambers interconnected by a cross-over passage having a continuous taper which constantly increases the cross-sectional areas from the first chamber inlet to the second chamber outlet. The tank allows the water to enter from a domestic water source at a point lower than the exit tube outlet with the outlet arranged at the tank's highest point obviating the entrapment of air within the tank. The tank has an internal configuration providing maximum internal volume while fitting into a limited space. The water flow through the tank follows a serpentine U-shaped path to promote water turbulence which will provide maximum heat transfer.

Water chilling tank for refrigerator

A refrigerator cabinet having a chilled water dispensing service area accessible from the exterior of the cabinet with a vertically extending water supply storage tank and filter cartridge assembly located in the fresh food compartment with the filter cartridge coextensive with one vertical edge of the tank positioning the cartridge upper inlet adaptor integral tube positioned adjacent an upper outlet of the tank. The tank has a serpentine storage volume comprising a plurality of substantially horizontal extending passes connecting the tank inlet and outlet with the tank uppermost pass extending at an inclined axis toward the tank outlet. The adaptor tube axis is inclined downwardly so as to be complementary to the upwardly inclined axis of the tank outlet whereby chilled water from the tank is purged of air and filtered just prior to being dispensed at the service area.

Refrigerator water storage and dispensing system with water filter

A beverage concentrate and water dispenser for a household refrigerator cabinet wherein multiple spouts with individual actuating and mixture diluting means are accessible from the exterior of the refrigerator cabinet. The dispenser includes a plurality of valves, fed with chilled water via a manifold from a water storage tank within the cabinet, for flow through jet nozzle aspirator means, operative for drawing beverage concentrate through a suction tube for mixing with the water prior to being dispensed. The dispenser concentrate-water mixture diluting means includes a valve in a water bypass passageway for selecting the proportion of bypass water dilution desired to be added to the concentrate-water mixture. An electrical switch is operative in sequence with resiliently biased valve plug members to delay the admission of source water under line or water main pressure into the manifold until the selected valve plug has been unseated.
