ABSTRACT:
A magnetic sealing device for a refrigeration appliance is disclosed that includes first and second pultruded gaskets, one of the gaskets being connected to the cabinet and the other of the gaskets being connected to the door. One of the gaskets has an extruded magnetic seal strip connected to it that interacts with a magnetically attracted material embedded near the surface of the other gasket. The magnetically attracted material is preferably a ferrous mesh screen and is embedded within at least one of the gaskets during the pultrusion process. When the door is closed against the cabinet the first and second gaskets substantially abut to effectuate a seal therebetween. The first and second gaskets are made of material having a low thermal conductivity so that the accumulation of condensate is reduced or eliminated on the sealing gasket and those portions of the surface of the refrigerator adjacent the gasket. Also, the profile of the gaskets may increase the heat transfer distance to further reduce the formation of condensate.
