Definitions

  • This invention relates to flame effect apparatus, for example for use in electric fires having a flame effect.
  • GB-A- 2385413 discloses a flame effect for an electric fire having a suspended fabric sheet visible behind a glass panel.
  • the base of the fabric is oscillated by an electric motor via a crank drive.
  • EP-A-1223385 discloses apparatus for simulating a fire and for installation in a fireplace to give the impression of an actual fire burning in the fireplace. Flame and fire simulated patterns are projected on to a window at the front of the apparatus.
  • the apparatus includes a foil suspended from near the top of a housing and means for moving the foil by impact on its base or at a point below its suspension.
  • US-B-6691440 discloses a fire construction for use in an open hearth and having a fuel bed, a set of reflective sheets above the bed and, above the sheets, a circulating drum or belt with short reflective strips on it. The strips are illuminated as the drum or belt rotates and their reflection from the plates gives the illusion of flames coming from the fuel bed.
  • a reflective sheet or strips suspended behind a window through which they may be viewed, and wherein the suspension itself is moved in rotary fashion by an electric motor.
  • the reflective sheet or strips are mounted via swivel joints or loose-fitting rings on a shaft which is moved in a circular motion about a horizontal axis parallel to the shaft itself. This may be easily achieved by suspending the sheet or strips on one or more shaft sections offset from its axis of rotation. Each section essentially rotates in a vertical plane.
  • the illumination source is placed so that it reflects off the reflective material which is moved by the motor to provide a realistic 3D flame effect looking like a real fire.
  • an electric fire apparatus mounted in a thin or full depth electric fire body may be provided with the appearance of a real fire.
  • the apparatus has, located near to top of a housing, a fixed horizontal-axis motor which rotates a driven element on which is suspended, via one or more sections of the shaft offset from its axis of rotation, a reflective material, either a full sheet or individual strips, using swivel joints or loose fitting rings.
  • the circular, vertical plane rotation of each offset part of the driven element, offset provides a 4-direction movement of the reflective material - upward, downward, forward, and rearward.
  • the reflective material is placed behind a glass or plastic panel of a choice of various colours, dependent on the desired flame colour or colours, and illuminated by either single or multiple colour LEDs or by various colour lamps.
  • the appearance of the simulated flame is that of a vertically upward rolling flame action along with a concurrent flame depth action, both at the base and at the tip of the flame.
  • Variations in the design configuration of the driven element and variations in the methods of attachment of the reflective material to this driven element can be used to create different flame patterns.
  • an electric fire is comprised of a frame chassis 7, an illumination source 1 located in its base, a horizontal axis motor 5 affixed to the frame chassis 7 near the top, and a driven element 8, which can be of various designs to create different 3D flame effect patterns, attached at one end to the drive shaft of motor 5.
  • the other end of the driven element 8 is secured in a bearing housing 11, which is affixed to the frame chassis 7 on the opposite side. Bearing housing 11 lies on the horizontal axis of rotation of the drive shaft of the motor 5.
  • a sheet of reflective material 2 is attached via swivel joints, loose fitting rings, or similar devices 9 to the driven element 8.
  • the reflective material 2 is located behind a glass or plastic panel 4, which is affixed to the frame chassis 7 behind an artificial fuel bed 3.
  • the light source 1 illuminates the reflective material 2 from the front underside and the horizontal axis motor 5 rotates the driven element 8 in a circular, vertical plane motion, thus moving the reflective material 2 in the following pattern: up/forward, up/rearward, down/rearward, and down/forward, as shown in Figures 2A to 2D .
  • the movement of the reflective material 2 in this pattern provides the desired upward rolling and 3D flame appearance.
  • the central axis of rotation of the driven element 8 is denoted 10 and corresponds to the horizontal axis of the motor 5 (not shown in Figures 2A to 2D ).
  • the offset portions of the driven element 8 are connected to a swivel joint, loose fitting ring, or similar device 9 which is attached to the reflective material 2.
  • the horizontal axis motor 5 rotates the offsets of the driven element 8 in a clockwise direction as seen in the Figures.
  • Fig 2A depicts the up/forward movement of the reflective material 2 when the offset portion 8 of the driven element is in around the 225 degrees from the vertical position.
  • the reflective material 2 passes the 270 degree from vertical position, at which the reflective material 2 is in its most forward position, to around 315 degrees from vertical, as shown in Fig 2B , depicting the up/rearward movement of the reflective material 2.
  • the horizontal axis motor 5 continues to rotate the offset of the driven element 8 in a clockwise direction, carrying the reflective material 2, it passes the vertical position, at which the reflective material 2 is in its highest position, towards the 45 degrees from vertical position shown in Fig 2C , corresponding to a down/rearward movement of the reflective material 2.
  • the reflective material 2 passes the 90 degree from vertical position, at which the reflective material 2 is in its most rearward position, towards the 135 degree from vertical position as shown in Fig 2D , depicting the down/forward movement of the reflective material 2.
  • the reflective material 2 passes the 180 degree from vertical position, at which the reflective material 2 is in its lowest position, and continuing back to the originating position as shown in Fig 2B .
  • the movement of the reflective material 2 from its lowest to highest positions provides the desired flame growth and flame tip action.
  • the movement of the reflective material 2 from its most forward to most rearward positions provides the flame depth, or 3D appearance.
  • the horizontal axis motor 5 is located such that its direction of rotation imparts an upward movement of the reflective material 2 when this material is at its closest position to the glass or plastic panel 4.
  • the continued rotation of the driven element 8 lifts the reflective material 2 to its highest position, thus simulating flame growth and flame tip movement. Further rotation of the driven element 8 translates the reflective material 2 to its most rearward position, thus simulating flame depth.
  • Variations in the driven element 8 design can be used to create different flame effect patterns.
  • the colours of the glass or plastic panel 4 and of the light source 1 may be adjusted to produce the desired flame colours. By using variable colour LEDs and suitable control circuitry, further variation over time may be easily achieved.
  • the electric fire may be provided with electrically powered heating elements of known type, and with likewise known means to blow hot air from the unit if desired.
