Patent

CA 2204106

An electric fireplace is provided having an improved flame simulating apparatus. The flame simulating apparatus includes a light source, a flame effect element for transmitting 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. An alternate flame effect element for reflecting light to produce a flame effect is also provided. A screen having a partially reflecting surface and a diffusing surface is positioned with the flame effect element extending proximate to the diffusing surface. An alternate screen is provided having a diffusing region through its thickness. 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. The screen may also be given a non-planar diffusing region such that the image of moving flames appears 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.

Cette invention concerne un foyer électrique à simulateur de flammes amélioré. Le simulateur de flammes comprend une source lumineuse, un transmetteur de lumière à effet de flamme, un élément à bandelettes réfléchissantes simulant l'effet dansant des flammes. Un deuxième élément à effet de flamme est également prévu. Un écran ayant une surface partiellement réfléchissante et une partie diffusante est disposé de sorte que l'élément à effet de flamme soit à proximité de la partie diffusante. Un deuxième écran comportant une partie diffusante dans son épaisseur est également prévu. Des bûches sur chenets sont placés vis-à-vis la partie partiellement réfléchissante de l'écran de sorte que son image puisse être projetée sur l'écran, les flammes simulées semblant danser entre les bûches sur chenets et leur image réfléchie. Dans une variante, l'écran peut comporter une zone diffusante non plane donnant l'impression que les flammes dansent derrière l'image projetée des bûches sur chenets. Un simili-coeur de foyer est également prévu dont l'image sera projetée la partie partiellement réfléchissante de l'écran qui simule un coeur de foyer.
