Abstract
An anti-condensation device having an electric heating element and method whereby said heating element is woven horizontally on an insulation plate and is sufficiently enlarged at the central portion to cause the temperature to be the same at every portion of the mirror face of the mirror in which it is used, and because of the heat produced by the heating element and conducted to the face of the mirror, when this mirror is installed in a bathroom or place where there is much steam and vapor, there is a method to cause the temperature of the reflective surface of said mirror to be 7.degree.-10.degree. C (18.degree. F) higher than that of temperature of the room or the adjacent atmosphere, so that it is possible to prevent water vapor dispersed in the air from condensing on the reflective surface of the mirror.
Claims4
A non-condensation mirror assembly adapted to be mounted generally vertically in a bathroom or like space wherein there is a relatively high concentration of water particles in the air, said assembly comprising a mirror consisting of a transparent glass plate having a light reflecting layer on its rear surface, and electrical heating means at said rear surface for heating the front surface of said mirror higher than the dew point of the air in said space, said heating means extending substantially coextensively with said mirror and being so constructed and arranged that more heat is imparted therefrom to the bottom portion of the front surface of said glass plate than to the upper portion.
