The de-fogging device and has an elongated heating element mounted within a housing. There is an elongated opening in the housing beneath the heating element for admission of air below the device and a second elongated opening in the housing above the heating element through which air heated by the heating element flows by convection. The device is mounted to a mirror or window and is positioned such that the heated air flows upwardly across the mirror or window. There is means for regulating the temperature of the heating element such that the heated air prevents any moisture in the air surrounding the mirror or window from condensing on it. |
