The present disclosure relates generally to artificial or simulated fireplaces and stoves, and more particularly to an electronic flame simulating assembly with an enhanced flickering light and modular design.
In simulated fireplaces, electronic flames or simulated flames are often used to provide the simulated fireplace with a more realistic visual flame or fire effect and also to play a role in decoration. Prior art flame simulation devices may include a light source and rotating reflector which are installed behind or beneath a screen wall with flame-shaped slots, also called a flame screen. Many prior art devices also include two-way mirrored back walls which temper the passage of backlighting to soften the edges of simulated flames created behind the back wall. However, these false back walls add substantial depth to the devices. These configurations take up more space, are more costly, and are more fragile in transit.
Many devices additionally include a simulated fuel bed that includes simulated logs and embers of the fire. The simulated fuel bed and logs must be independently lit by a separate light source(s) adding further cost and complexity to the devices.
Therefore, there is a perceived need in the industry for a simulated fireplace that includes a fuel bed and flame screen that have an enhanced simulated burning visual effect, that does not require additional back lighting components which can significantly increase the cost of manufacture and cost or operation of the simulated fireplace. Furthermore, there is also a desire to reduce cost of operation of simulated fireplaces, namely, reduced electrical needs of the simulated fireplace.
The present disclosure provides in one respect, a flame simulating assembly with a reflected flickering light system that includes a light source that shines through a rotating flicker rod with a plurality of flicker elements. Some of the light from the light source is reflected off of the rotating flicker element up towards a flame screen to create a flame effect. Some of the light from the light source passes though the rotating flicker elements onto an angled reflector, or mirror, that reflects light up onto a simulated fuel bed. The light that is reflected off the mirror first passes through gaps in the flicker elements as the flicker rod rotates and the terminal ends of the flicker elements clip into and out of the light path. The dipping flicker elements creates a fluttering light effect due to the flicker elements “intermittently dipping” into the light path. This fluctuating light is reflected onto the logs and ember bed in front and creates a dancing effect, which simulates glowing embers and burning logs. The logs and ember bed may or may not be additionally lit from the inside. A significant portion of the emitted light is also reflected from the flicker elements and up through a screen wall with flame-shaped slots and openings, and onto an imaging screen or wall, to further simulate flames.
Another novel aspect of the present disclosure solves the problems of the prior art by providing a flame simulating assembly with a flame screen that has non-continuous flame-shaped segments that have sharper edges, are generally wider than they are tall, and taper outwardly from the center to the edges of the flame screen. The non-continuous flame-shaped segment can, for example, be non-continuous in a vertical direction, or along the beam angle of the light source. This unique flame shape configuration results in a more pronounced triangular shape of the resulting simulated flame. The triangular outline shape of the non-continuous cutouts can create an artificial fire shape that better resembles a real fire, and that is wider at the bottom than at the top, with greater intensity at the center than at the edges. In alternative embodiments, the non-continuous cutouts can have an outline of any other shape including an elongated triangular, rectangular, oval, parabolic, sinusoidal, etc. shape.
Further embodiments can include an improved simulated light assembly which can channel, or direct, light at a desired forward angle and prevent side spill of light to provide for enhanced flame shapes for a more realistic flame. While the terms, channel and direct, are used, this is not intended to limit the function of the device. A portion of the light may be channeled while other portions of the light may diffuse through the channel walls.
A further novel aspect of the present disclosure provides a flame simulating assembly with an integrated ember bed and flame screen assembly. The integrated ember bed and flame screen may be molded as a single piece of plastic, providing many advantages. The ember bed can be lit from inside by the flicker element, creating a glowing ember bed, in addition to projecting the simulated flame through an integrated flame screen. The cost is reduced since the flame screen may be made from the same plastic instead of steel, injection molded instead of stamped in a secondary forming operation, and the depth can be decreased due to the elimination of a barrier between flicker element and ember bed. The cutout shapes of the flame screen may also be advantageously punched out, either before or after injection molding. Separate logs or grate elements can be attached or built into the molding process. The molding process can be any molding process including injection molding, vacuum molding, or blow molding. Moreover, in some embodiments, the integrated assembly can be fused together after discrete portions are molded.
Accordingly, it can be seen that the present disclosure provides a unique and novel flame simulating assembly with improved flame appearance, better design, fewer parts and less cost.

Generally, a novel, electronic simulated fireplace is disclosed. As noted above, traditional electric or electronic fireplaces suffer from a number of drawbacks including complicated manufacturing, a large number of parts, poor quality flame projections, and housing sizes that are too large for many locations. The instant disclosure provides a number of advantages over the prior art. The instant disclosure provides a number of sub-assemblies that individually, or in combination, provide a more realistic moving image of fluctuating flames, a more realistic glow for an ember bed, a more compact design, or a more integrated design.
In an exemplary embodiment, illustrated in
The interior of the housing can provide space for various internal components of the electric fireplace, including a heater/blower unit (not shown in this embodiment) which provides a warm air flow from the fireplace unit 100 and further including a flame simulation assembly 120 which provides the visual effect of moving flames on the firebox rear wall 110. Referring briefly to
The flame simulation assembly 120 can generally include a flame simulating light source 130, a flicker element 140, and a flame simulator element (flame screen) 150 all of which work in concert to create the shape and appearance of moving flames on the firebox rear wall 110. In the illustrated embodiment, the rear wall 110 functions as an imaging screen, and the flame simulating components are located in front of the rear wall 110. The rear wall panel 110 may alternatively have other shape configurations and/or have areas of matte or glossy finishes depending on the desired flame effect and the configuration of the flame simulating assembly 120 located forwardly thereof. In addition to the flame simulation assembly 120, the fireplace 100 may include an ember bed simulation assembly 160. In some embodiments the ember bed simulation assembly 160 is a fully, or partially, separate assembly from the flame simulation assembly 120. In other embodiments, the ember bed simulation assembly 160 is integrated into, and with, the flame simulation assembly 120. As will be discussed in detail below, the various embodiments can provide an enhanced realistic flame and ember simulation. In some embodiments, various sub-assemblies can be integrated together to decrease the overall footprint of the fireplace assembly.
In the first embodiment, as shown in
In general, the flame simulation assembly 120 can include a single flame simulating light source 130 which can be used to illuminate both a flame simulation assembly 120 and an ember bed simulation 160 assembly—without additional light sources. The flame simulation assembly 120 can generally include the flame simulating light source 130, a light shield 131, a rotating flicker element 140 which can angle the light generated by the light source 130, and a flame screen 150. The flame simulation assembly 150 can be a single subassembly housed by a flame simulation housing 122. The flame simulation housing 122 can have two sidewalls 124a, 124b, a lower rear wall 126, and an upper rear wall 128. In the illustrated embodiment, the lower rear wall 126 can have a generally upside-down “L” shape that includes an upper horizontal piece 126a and a lower vertical piece 126b. Extending upward and forward, at an angle, from a forward edge of the upper horizontal piece 126a can be the flame screen support 128. The flame screen support 128 can be disposed in an angle of approximately 50 degrees to 70 degrees from the horizontal. In the illustrated embodiment the flame screen support 128 has a flame screen 150 integrated directly thereon.
The single light array, or source, 130 can be disposed beneath the flame screen 150 proximate on the lower rear wall 126 of the flame simulation housing 122. The light array 130 can include a plurality of bulbs or light emitting diodes (LEDs) 134 disposed on a printed circuit board (PCB) or mounted on a support 132 and wired together. In the exemplary embodiment, the light array 103 is disposed against the lower rear wall 126b and oriented such that the PCB 132 is parallel to both the rear and front walls 102a, 102b and the bottom and top walls 104a, 104b. In an alternative embodiment (see
As noted above, the flame simulation assembly 120 can additionally include a light channeling shield, light focusing system, or light path guidance system, 131 to further optimize the realism of the flames generated thereby. Referring now to
In an alternative embodiment, a light source 132 and light channel 131 can have LED groups 136′, and the associated shield walls 135′, closer in the middle with gradually farther apart toward the outer edges. For example, as shown in
Referring back to
Referring to
The light from the light source 134 can pass through the light shield 131 such that it is directed towards the rotating flicker rod 140. The light that hits the flicker element, as shown via arrow A, can (A) be reflected through the slotted flame screen, as shown via arrow B, and onto the imaging wall, forming a simulated flame, and (B) pass intermittently through the flicker element, as shown via arrow C, and onto the reflector, where the light is reflected, as shown via arrow D, onto simulated ember, or fuel bed, 160 creating a glowing or burning ember effect.
As noted above, light from the LEDs 134 is directed through the light channel 131 towards the flicker element portion 140 of the flame simulation assembly 120. Generally, the flicker element 140 can be disposed on a flicker rod 142 which turns about an axis that is generally located vertically above at least a portion of the LEDs 134, for example above the light path A. The rod 142 can be supported by the light simulation housing side panels 124a, 124b. Further, a motor (not shown) can be secured to one of the light simulation housing side panels 124a, 124b and retain one terminal end of the rod 142 therein. The motor can rotate the rod 142 such that the flicker element 144 rotates with the rod 142 to create a flicker effect. In the illustrated embodiment, the flicker element 144 can be a single piece of reflective material that is threaded onto, and secured to, the rod 142. In some embodiments, the flicker element can be stamped as a single piece of material, as shown in
As illustrated, the rod 142 of the flicker element 149 is disposed forward of the LED panel 132, towards the front wall 102a, and vertically above the LEDs 132, away from the bottom wall 104b. In use, as the rod 142 is rotated by the motor, the distal ends of the paddles 144 move into and out of the path of the light from the light source 132, such that the paddles “dip” into the path of light, see light path arrows C and D, as shown in
In use, the light from the LED array 130 is directed, by the light shield 131, at the flicker element 140. A portion of the light is reflected against the paddles 144 upward towards the flame screen 150. A further portion of the light passes through the flicker element 140 towards the ember bed reflector 170, which is discussed further below. Therefore, it can be seen that the simulated flame assembly 120 provides a unique solution to the problems of the prior art by providing a simulated flame assembly 120 with a reflected flickering light that relies on a single light source 130 to light the fuel bed 160 and simulated flame yet provides a simulated burning effect to both. Consequently, component manufacturing costs and electricity usage of the simulated fireplace are reduced.
The light that is reflected upward from the flicker element 140 is directed towards the flame screen 150 before passing to the back wall 110. The flame screen can selectively permit the reflected light, from the flicker element, through to the back wall. Advantageously, the exemplary flame screen includes vertically non-continuous flame cut outs which are segmented along the path of reflected light. The non-continuous flame screen can, for example, be non-continuous in a vertical direction, or along the beam angle, or light path, of the light source as shown in
Prior art flame screens 50, as shown in
The flame segments 152, 152′ can be arranged in a generally triangular pattern, as shown in
The exemplary flame screens 150, 150′ can permit the light that is reflected up from the flicker element 140 to pass through the non-continuous segments 152, 152′ to create realistic flames on the rear wall 110 of the housing 101. The broken-up flames from the flame screen 150 are seen, in conjunction with an optional glow effect from the rear of the flame simulation housing to create a realistic flame.
As discussed above, some of the light, shown via arrow C, that is directed from the light source 130 towards the flicker element 140 passes by the flicker element 140 as the paddles 144 clip in and out of the path of the light. The light that passes by the flicker element can continue to the ember bed reflector 170, as seen in

In a further alternative, exemplary embodiment illustrated in
The single light array 330 can be disposed beneath the flame screen 350 on the lower rear wall 326b of the flame simulation housing 322. The light array 330 can include a plurality of bulbs disposed on a printed circuit board (PCB) or mounted on a support 332 and wired together. In the exemplary embodiment, the light array 330 can be oriented such that the PCB 332 is at an angle relative to both the rear and front walls and the bottom and top walls and the LEDs are angled upward. The angle of the PCB and the light source can be approximately 20 degrees to 40 degrees from the bottom panel of the housing. In some embodiments, the light array 330 can be a panel that includes a plurality of sources. The light channeling shield 331 can similarly be angled upward, at an angle of approximately 70 degrees, in parallel to the upper angled piece 326a to direct the light towards the flicker element 340. In some embodiments, the light shield 331 can be integrated, or molded, as part of the ember bed 360 and log mold 370 and/or molded with the flame screen 350, or all the aforementioned components can be molded together. The upward angle of the light channeling shield 331 and the light source 330 itself can direct a portion of the light source directly towards the ember bed 360 and logs 370. Like the other embodiments, the light source 330 projects light at the flicker element, as shown as arrow A′ such that some light, shown as arrow B′, is reflected towards the flame screen 350, as discussed above, and some of the light, shown as arrow C′, is directed towards the ember bed 360 and logs 370 as the flicker paddles 344 dip in and out of the light path. The flicker element 340 can include the rod 342 and the flicker rod 343 can be disposed above, and forward of, the light channeling shield 331 and light source 330. The ember bed 360 and logs 370 can be a single piece molded from plastic that is selectively thinned in strategic locations (not shown), such that light may pass through the thinned portions of the plastic material, creating the glowing and/or burning ember effect. Due to the relative locations and steep angles of the light source 330, the light channel 331, flicker element 340, and the ember bed 360 can be disposed closer together, thereby permitting the depth of the device 300 to be further reduced. In some embodiments, the ember bed 360 and the flame simulation housing 322 can be integrated into a single unit, like the embodiment of
Although the embodiments shown herein illustrate a simulated flame with a front projection system onto an imaging wall, it would be appreciated by one skilled in the art that the simulated flame assembly described herein may be adapted for a rear projection configuration, or an indirect projection using one or more mirrors. In particular, instead of light projected onto an imaging wall at the back of the enclosure, the light could be projected forward onto a rear surface a light-transmitting imaging screen that is positioned forwardly and closer to the ember bed.
Further, it would be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be within the scope of the present invention. While the present disclosure provides for various embodiments, it is intended for the subassemblies of the various embodiments to be discrete subassemblies that can be used in the various embodiments interchangeably.
