Abstract

An air flow control assembly in a refrigerator having a freezer compartment on top and a fresh food compartment on the bottom separated by a partition and interconnected by an air duct located at the rear of the compartments. The air duct has an air inlet opening in the freezer compartment and an air outlet opening in the fresh food compartment. A movable damper opens and closes the air duct outlet opening and a storage pan is located in air flow communication with the air duct outlet opening. The storage pan has a stationary cover. There is a movable control mechanism located at the front of the storage pan, a push rod linkage member cooperating at one end with the damper to open and close the air duct outlet opening upon movement of the push rod linkage member and the other end is connected to the control mechanism for moving the push rod linkage member. With this arrangement, the user of the refrigerator may move the control mechanism to control the amount of cold air flowing around the pan and, thus, control the temperature inside the pan.
