Abstract
The embodiment of the invention disclosed herein is directed to a new and improved method and apparatus for preventing condensation from forming about refrigerator and freezer doors. Warm air produced by the compressor of a refrigerator or freezer unit is channeled either directly or indirectly therefrom to flow vertically along the peripheral sealed edges of the freezer door to prevent condensation from developing therealong. The heated air from the compressor is directed through a vent or outlet port formed in a kick plate or through outlets formed in the housing at a location near the bottom vertical edges of the door. This will provide vertical columns of warm air to flow therealong and prevent condensation.
Claims10
In a refrigeration unit, the combination comprising:
- a housing for defining a refrigeration space, an opening formed in said housing, a door secured to said housing and over said opening, said door providing a seal about the periphery of said opening, a compressor unit secured to said housing and giving off heat to the surrounding air exterior of said refrigeration space, air flow means for directing the heated air produced by said compressor unit to flow along at least one edge of said door and the housing portion immediately adjacent thereto for preventing condensation from developing therealong and along said housing portion, and switch means actuated by said door for de-energizing said compressor and temporarily terminating the warm air flow when said door is open.
In a refrigeration unit the combination comprising:
- a housing for defining a refrigeration space, an opening formed in said housing, a door secure to said housing and over said opening, said door providing a seal about the periphery of said opening, a compressor unit secured to said housing and giving off heat to the surrounding air exterior of said refrigeration space, and air flow means for directing the heated air produced by said compressor unit to flow along at least one edge of said door and the housing portion immediately adjacent thereto for preventing condensation from developing therealong and along said housing portion, said air flow means comprising a pivotal louver, and means responsive to opening and closing of said door and coupled to said pivotal louver for closing said pivotal louver when said door is open and for opening said pivotal louver when said door is closed.
A method of preventing condensation from forming about the outer periphery of a freezer door and the housing immediately adjacent thereto comprising the steps of:
- operating a compressor for producing a refrigerating cycle, cooling the compressor by transferring the heat therefrom to the surrounding air, directing the heated air produced by said compressor along the edges of a freezer door, and de-energizing said compressor in response to opening of said door.
