Patent ID: 8746901

Claim:
A mirror having an image viewing surface which resists fogging caused by condensation of water vapor on said viewing surface, said mirror including a mirror assembly comprising; a. a reflective mirror plate, b. a hollow body which supports said reflective mirror plate, c. a water reservoir for warm water located within said hollow body, said reservoir being in thermally conductive contact with said reflective mirror plate, and d. a water supply conduit in fluid-tight connection with said water reservoir, said water supply conduit having a larger transverse cross-sectional area than that of said water reservoir, said water reservoir including a cavity formed between a front wall which supports said reflective mirror plate, a rear wall spaced rearward of said front wall, and left and right side wells, said water supply conduit being located above said water reservoir and having a tapered transverse cross-section bore which has a smaller lower end which joins an upper end of said water reservoir, and a larger upper end which is terminated in a water-fill aperture for introducing warm water into said water supply conduit and said water reservoir, said water reservoir having the shape of a tapered tubular section which has a bore that conformally joins at a lower smaller cross-section end thereof the upper end of said water reservoir, said water supply conduit curving rearwardly of said front wall of said body, thereby locating the plane of said water-fill aperture rearward of said front and rear walls of said body.
