Abstract
Abstract A conventional mirror will quickly fog when exposed to the extremely humid environment of the shower. This is because the moisture contained in the warm ambient air condenses on the relatively cooler mirror surface. An effective way to remedy this problem is to heat the mirror surface to a sufficient temperature to combat condensation of the moisture in the ambient air. This invention provides an effective method and apparatus to combat fog formation. This invention utilizes relatively simple construction to provide a low cost, safe, highly portable, efficient and effective method and apparatus to provide a non fogging shower mirror. To achieve this, the inventive device (10) incorporates a mirror, attached to a reservoir (14). This reservoir (14) holds a thermal mass of warm water. The thermal energy of this warm water is conducted through the mirror (12) substrate to the mirror surface, thus raising the temperature of the mirror (12) surface sufficiently to effectively combat moisture condensation and thus combat fog formation. The reservoir (14) includes a filling orifice (18), suspension hook hole (16) and water exit port (20). The user fills the inventive device (10) with water through the filling orifice (18) and hangs the inventive device (10) by a hook secured to the shower wall and inserted in suspension hook hole (16). The water in the reservoir (14) slowly escapes through the action of gravity through water exit port (20), thus leaving an empty reservoir.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
93 words
A non-fogging mirror, comprising: (a) a volume defining member for defining a volume for containing water; (b) a reflective member secured to said volume defining member, and together with said volume defining member forming a reservoir for holding water in thermal contact with said reservoir, said reflective member forming a front wall of said reservoir; (c) an orifice defined in the upper portion of said reservoir; and (d) an exit orifice defined in said reservoir positioned configured and dimensioned to slowly empty said non-fogging mirror of said water through the action of gravity.
Claim 2
Dependent Claim
