Benefits of technology

[0004]The following presents a simplified summary of the invention in order to provide a basic understanding of some example aspects of the invention. This summary is not an extensive overview of the invention. Moreover, this summary is not intended to identify critical elements of the invention nor delineate the scope of the invention. The sole purpose of the summary is to present some concepts of the invention in simplified form as a prelude to the more detailed description that is presented later.
[0005]In accordance with one aspect of the present invention, a refrigeration appliance is shown comprising a freezer compartment maintaining air at a temperature of zero degrees Centigrade or less and a fresh food compartment maintaining air at a temperature greater than zero degrees Centigrade, an opening between the freezer compartment and fresh food compartment, the opening configured to allow air to flow from the fresh food compartment to the freezer compartment, an air tower adapted to be located within the fresh food compartment, the air tower configured to be in fluid communication with the fresh food compartment and freezer compartment, and a damper door adapted to be secured within the air tower and configured to pivot between a closed position and an open position, wherein the closed position of the damper door partially restricts flow through the air tower. In addition, air is adapted to

Problems solved by technology

Furthermore, when the fresh food compartment is filled with perishable items by a user, the flow of cool air into the fresh food compartment can be obstructed.
This may occur because cool air falls to the bottom of the fresh food compartment, making it difficult to circulate the cool air near the top.
