Patent ID: 7685914

Claim:
A food slicer comprising a food sliding carriage, an electrically powered motor rotating a cooling fan and having a power train for driving a slicing blade, said motor and said power train being mounted within an enclosure, said blade being mounted at the exterior of said enclosure, said motor having a frame which houses electrical windings, said motor frame extending through a motor retaining aperture in a first partitioning wall of an interior motor compartment, said motor frame contacting said first partitioning wall at said aperture to be sealingly mounted to said first partitioning wall, said fan being mounted immediately adjacent to a non-contacting aperture in a second partitioning wall within said enclosure to create an air discharge compartment in which said fan is located on a side of said second partitioning wall remote from said motor retaining aperture in said first partitioning wall, said air discharge compartment being defined by said second partitioning wall and by the exterior wall of said enclosure, said first partitioning wall being an interior wall of said enclosure which defines said motor compartment and which extends to the exterior wall of said enclosure near said air discharge compartment to exhaust air from said motor compartment into said air discharge compartment, said enclosure having at least one intake port, at least one exhaust port in said exterior wall of said enclosure at said air discharge compartment, an air flow path being created by cooling air entering said enclosure through said at least one intake port to pass around and cool said power train on one side of said first partitioning wall and the air then moving into intimate contact with said electrical windings within said frame and the air is then directed through said non-contacting aperture of said second partitioning wall remote from said motor retaining aperture by being drawn inwardly by said fan and the air then being exhaused directly from said air discharge compartment of said enclosure through said at least one exhaust port without any interference from any intermediate structure between said fan and said at least one exhaust port so that the air flows from said fan directly out of said enclosure, and the discharge area of said at least one exhaust port being sufficiently large to permit the exhausing air to exit said enclosure without development of significant back pressure to resist the direct exiting of the air.
