International Classification:

F25D 11/02

US Classification:

62 90, 62187, 62440

Abstract:

A refrigerator freezer having an upper refrigerator compartment and a lower below freezing freezer compartment. The upper compartment can be a convertible compartment selectively operable by the user as an above freezing refrigerator compartment or as a below freezing freezer compartment. The evaporator for supplying refrigerated air is located in the upper compartment along with an auxiliary heater and upper compartment thermostat to control the temperature in the upper compartment. A control discharges an amount of refrigerated air to the upper compartment for refrigerator operation and a larger amount of refrigerated air for freezer operation. The control also energizes the auxiliary heater under control of the upper compartment thermostat during refrigerator operation to assure above freezing temperatures in the upper compartment. A low ambient heater can be provided for the upper compartment for use of the refrigerator freezer in low ambient temperature conditions such as an unheated garage.

Abstract:

An acoustical vibration dampening system for a rotatable blade comprises at least one section of a rotatable blade and a layer of acoustic damping material coupled to a portion of the at least one section of a rotatable blade. A fan blade comprises a first structural section of a fan blade, a second structural section of the fan blade, and a layer of acoustic damping material provided between the first structural section and the second structural section of the fan blade. A method of making a fan blade with acoustic damping comprises forming at least two sections of a fan blade, and disposing an acoustical vibration dampener between the at least two sections of the fan blade.

Appl. No.:

9/036298

Inventors:

Quynh Hoang - Evansville IN

John Ricard Wisnoski - Haubstadt IN

Assignee:

Whirlpool Corporation - Benton Harbor MI

International Classification:

H01R 1360

US Classification:

439528

Abstract:

A blind connector is provided on an access panel. The access panel covers an access opening in a wall of an apparatus. The wall separates an access area from a connective element such as a harness on the other side of the wall. The blind connector holds the connective element by a connector on the connective element. The blind connector makes the connective element readily available when the access panel is removed. This improved access panel provides easy access to an ice maker harness in the freezer portion of a refrigerator-freezer for the later connection of an ice maker kit.
