Concealed upstream air tower guide vanes

Abstract:

A refrigerating appliance includes an evaporator for providing cooled air to a refrigerating compartment. An air tower defines an air channel for directing the cooled air from the evaporator to the refrigerating compartment. A plurality of air-directing guide vanes is positioned within the air tower and proximate a top of the air channel. The air directing guide vanes direct the cooled air from the air channel to define redirected air that is delivered in a direction toward an upper cool-air slot defined within the air tower. The redirected air from the air-directing guide vanes travels through the upper cool-air slot at substantially the same velocity as the cooled air entering the air-directing guide vanes. The redirected air is directed through the upper cool-air slot and toward at least one upper corner of the refrigerating compartment.
