| 20090220221 | FLAME SIMULATOR OF ELECTRIC FIREPLACE - An apparatus for flame simulation in an electrical fireplace which improves the realism of leaping and flickering flames, comprising a fixed light source, simulated charcoal, and a flame display screen which is arranged above the fixed light source. The simulated charcoal is located in front of the flame display screen. A twisted-style light reflector is located behind the flame display screen and is driven by a motor mounted inside the wall of the electrical fireplace. By rotating the twisted-style light reflector, light emitted from the fixed light source is reflected onto the flame display screen so the simulated dynamic leaping and flickering flames can be seen. The fixed light source also illuminates the simulated charcoal to produce an effect of burning charcoals. A heater produces warm air that is expelled from the fireplace. | 09-03-2009 |
