Abstract
An electric fireplace is provided having an improved flame simulating apparatus. In one aspect, the flame simulating apparatus includes a light source, a flame effect element for reflecting light to produce a flame effect, and a flicker element having reflective strips for reflecting light from the light source for subsequent reflection by the flame effect element. A screen having a partially reflecting surface and a diffusing member is positioned with the flame effect element extending proximate to the diffusing member. A fuel bed is positioned immediately adjacent to the partially reflecting surface of the screen to produce an image of the fuel bed on the screen with the image of moving flames appearing to emanate between the fuel bed and its reflected image. An alternate screen is provided having a non-planar diffusing member which causes the image of moving flames to appear to emanate from behind the reflected image the fuel bed. A fire wall simulating apparatus is also provided to provide a reflection of a simulated fire wall on the partially reflecting surface which appears to be a fire wall behind the fuel bed.
