Abstract
Abstract A cosmetic cabinet incorporating a Peltier cooling unit in the door thereof, the cooling unit removing heat from the interior of the cabinet and dissipating heat by means of a finned heat dissipator arrangement having a plurality of elongated vertically disposed cooling fins, the cabinet also incorporating a mirror at the outer surface of the cabinet''s door, the rear surface of the mirror being adjacent the cooling fins whereby the mirror absorbs a portion of the heat dissipated by the cooling fins and prevents fogging of the mirror''s outer surface.

The cosmetic cabinet according to claim 1, wherein said cooling unit includes a Peltier cooling element and a finned cooling structure with a broad base portion and a plurality of spaced vertically oriented parallel fins extending perpendicularly therefrom, said Peltier cooling element having a broad heat absorbing surface disposed inwardly toward the interior of said compartment and having an oppositely disposed broad heat dissipating surface thermally conductively coupled to said broad base portion of said finned cooling structure, the outer extremities of said fins being disposed adjacent said rear surface of said mirror.
Claim 4
Dependent Claim
76 words
The cosmetic cabinet according to claim 2, wherein said cooling unit also includes a broad thermally conducting inner plate mounted on said heat absorbing surface of said Peltier cooling element and wherein said cooling unit further includes a broad thermally conducting outer plate mounted on said heat dissipating surface of said Peltier cooling element, said outer plate being disposed between and in thermally conductive contact with both said Peltier cooling element and said finned cooling structure.
Claim 5
Dependent Claim
30 words
