WATER HEATED MIRROR FOR CONDENSATION CONTROL
First Claim
1. An indoor water heated mirror for use in steamy bath areas comprising a shell having a back wall with upstanding side walls and top and bottom end walls, a glass mirror panel glazed to the outer marginal edges of said side and end walls in fluid-tight engagement therewith to define an interior fluid-tight chamber, said mirror panel and said shell defining a water conduit means for the flow of hot water on the reverse surface of said panel in heat exchange relationsHip with the panel to heat the panel and prevent steam from condensing thereon, hot water inlet means in the top wall of said shell, said side and bottom end walls having drain openings therein for the gravity drainage of spent water from the interior of said chamber, said drain openings causing the water to flow uniformly within the chamber wherein structure is provided within said chamber defining a flow path for hot water to cause flow of water within the chamber in paths to pass substantially uniformly over the reverse surface of said glass mirror in heat exchange relationship therewith.

Abstract
The water heated mirror includes a shell and a glass mirror panel which define a conduit type chamber on the reverse surface of the mirror panel in heat exchange relationship therewith through which hot water flows to elevate the temperature of the glass panel and prevent condensation of moisture on the reflecting surface thereof. The side and bottom end walls of the shell are provided with drain openings for the gravity drainage of spent water from the interior of the chamber.

2. The indoor water heated mirror as defined in claim 1 and further characterized in that the side walls of said shell are each provided with a plurality of spaced apart inwardly directed notches having a generally V-shape with upper and lower wall portions, the upper wall portions having said openings formed therein, said lower wall portions defining a downwardly inclined slope for the gravity flow of water from the mirror after the water drains through the openings.
-
3. The indoor water heated mirror as defined in claim 2 and further characterized in the provision of a plurality of spaced apart recesses in said back wall extending into contact with the reverse side of said glass mirror panel to structurally rigidify the mirror assembly and to define flow paths for water through said interior fluid-tight chamber.
-
4. The indoor water heated mirror as defined in claim 1 and further characterized in the provision of a sheet of plastic material secured to the reverse surface of said mirror panel to insulate said panel from the hot water flowing through said interior chamber, said sheet of plastic material extending between the glass mirror panel and the outer marginal edges of said side and end walls to thereby glaze the glass mirror panel to the outer marginal edges of the side and end walls in said fluid-tight engagement.
-
5. The indoor water heated mirror as defined in claim 1 wherein said structure within said chamber comprises a plurality of cylindrical recesses struck out of the back wall of said shell and extending towards and engaging said mirror panel.
-
6. The indoor water heated mirror as defined in claim 1 wherein said structure comprises a plurality of elongated recesses struck out of the back wall of said shell and extending towards and engaging said mirror panel.
