Abstract
Description
- The invention relates generally to the field of fireplaces. More particularly, the invention relates to screenless flame projection devices that can be removably seated in the hearth of a fireplace and activated to project flame-like light onto the back panel of the fireplace to simulate the visual effects of an actual wood-burning fireplace.
- Fireplace are incorporated in to homes to provide a source of heat and for aesthetic reasons. There are currently several fireplace options available to consumers including traditional wood-burning fireplaces, gas burning fireplaces, and electric fireplaces. Real wood-burning fireplaces generally offer the greatest heat-production and aesthetics, but require more set-up and maintenance time to operate. Wood-burning fireplaces also present a safety hazard due to the risk of fire spreading into the home and can be inconvenient because logs must be provided. Gas-burning fireplaces offer a real flame and convenience, but lack the natural sound, flickering, and shadowing associated with wood fires. Gas-burning fireplaces also present safety hazards due to the risks of explosion associated with natural gas combustion. Electric fireplaces do not offer a real flame, but have many safety and convenience features.
- Wood-burning fireplaces incorporated in dwelling are sometimes retrofitted to be gas burning or electric. Such retrofitted fireplaces retain much of their original aesthetics while offering better convenience and safety. The cost of retrofitting a wood-burning fireplace to gas or electric, however, is relatively high.
- The invention relates to the development of a standalone screenless flame projection device that can be removably seated in the hearth of a conventional fireplace and activated to front project flame-like light onto the back panel of the fireplace to simulate the visual effects of an actual wood-burning fireplace. The invention allows a wood-burning fireplace to be adapted to an electric fireplace without any retrofitting. It also can be used with a simulated fireplace that is not permanently installed in a dwelling. The screenless flame projection devices described herein differ structurally from the projection screen-dependent flame simulation systems that are integrated into conventional electric fireplaces in that they project light from the front of the fireplace to the back panel of the fireplace rather than projecting reflected light from the back of the fireplace onto a projection screen located in the middle section of the fireplace. The invention thus provides a lower cost and often more convenient alternative to conventional electric fireplaces.
- The flame projection device can include a housing; a flame light system that can include a light source, a spindle having reflectors attached thereto, a mechanical device for rotating the spindle, and a flame cutout panel; a hot air generator, a simulated fuel source, a power source, and a controller. The flame light system and controller can be installed on the housing to form a self-contained unit (i.e., the flame projection device) capable of being positioned inside a firebox of the fireplace (e.g., by simply seating the device on the hearth floor). Light produced by the light source can be projected onto the reflectors. As the spindle rotates, light is reflected off of the reflectors through one or more flame-shaped cut-out sections onto the rear wall of the firebox to simulate the “dancing” appearance of actual flames produced by burning wood. The flame projection device might also be used with a simulated fireplace that is not permanently installed in a dwelling.
- Accordingly, the invention features a flame projection device for use with a real or simulated firebox comprising a hearth floor and rear wall. The flame projection device includes a housing; a flame light projection system incorporated in the housing and configured to project light in the form of simulated flames; and a controller for reversibly activating the flame light system. The housing can be reversibly positioned on the hearth floor and the flame light projection system can be activated to project simulated flames onto the rear wall of the firebox. The flame light projection device can lack a flame projection screen.
- The flame light projection system can include a light source, a rotatable spindle, a plurality of reflectors, and a flame cutout panel, wherein the light source is arranged to direct light to the reflectors and the reflectors are arranged to reflect the light at the flame cutout panel. The housing can include a front portion and a rear portion, and the light source and flame cutout panel can be located in the rear portion of the housing and the rotatable spindle and reflectors can be positioned in the front portion of the housing.
- The flame projection device might also include a simulated fuel source fastened to the top of the housing and/or a hot air generator positioned in the housing and controllable by the controller.
- In another aspect, the invention features the combination of a real or simulated fireplace and a removable flame projection device, wherein the fireplace lacks a permanently attached means for simulating a flame, the fireplace includes a hearth and a back wall; and the flame projection device includes a housing, a flame light projection system incorporated in the housing and configured to project light in the form of simulated flames, and a controller for reversibly activating the flame light system. In the combination, the housing can be reversibly positioned on the hearth floor and the flame light projection system can be activated to project simulated flames onto the rear wall of the firebox. The flame light projection device can lack a flame projection screen.
- In the combination of a real or simulated fireplace and a removable flame projection device, the flame light projection system can include a light source, a rotatable spindle, a plurality of reflectors, and a flame cutout panel; and the light source can be arranged to direct light to the reflectors and the reflectors are arranged to reflect the light at the flame cutout panel.
- Another aspect of the invention features a method for projecting simulated flames onto the rear wall of a firebox. The method can include the steps of: (a) positioning a flame projection device on the floor of a hearth of the firebox; and (b) activating the flame light projection device to project simulated flames onto the rear wall of the firebox. In the method, the flame projection device can be inserted through the front of the firebox before being positioned on the floor of the hearth of the firebox. The flame light projection device can lack a flame projection screen.

As shown inFIGS. 2 and 5A , the standalone screenlessflame projection device 10 can be removably placed into afireplace 80 by seating the device on the floor of thehearth 82 of thefirebox 84 with the simulatedgrate 22 facing outward and the projected simulated flame output being aimed at theback wall 86 of thefirebox 84. Turning theflame projection device 10 on via thecontroller 70 causes the light from thelight source 30 to be projected onto thereflectors 34 as they rotate with thespindle 36. The light reflected from thereflectors 34 is then passed through theflame cutout panel 38 and projected onto theback wall 86 of thefirebox 84 as simulatedflames 33 as shown inFIGS. 2 and 3 . - The
flame projection device 10 is preferably sized to fit within a conventional firebox, e.g., with a footprint similar to or slightly larger than a conventional fuel source grate. For example, theflame projection device 10 may have a width between 25-100 cm, a height of between 10-100 cm, and a depth of between 12 and 50 cm (e.g. 38×28×20 cm+/−10%). To provide a good flame effect, therear portion 26 of thehousing 20 is preferably positioned the floor of thehearth 82 about 0 to 45 cm (more preferably, 0.5-10 cm or less than 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, or 40 cm) from theback wall 86 of thefirebox 84. The weight of theflame projection device 10 should be light enough for the average person to transport, e.g., less than 20, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, or 3 kg. - The
housing 20 can take the form of any device suitable for holding the other components of theflame projection device 10 in a working configuration. Preferably, thehousing 20 is arranged as shown inFIG. 4 with a front portion 23 (including the simulated grate 22), abottom portion 24,side portions rear portion 26, which together define aninterior compartment 28. The frontal portion of thehousing 20 may, for example, be arranged to simulate the appearance of a conventional fuel source grate, e.g., by including the simulatedgrate 22. Theside portions rear portion 26 of thehousing 20 may be arranged as flat panels that may have a quadrangular or other polygonal or irregular shape. Preferably, thesimulated grate 22 is large enough to hide much of the other outer portions of thehousing 20 from being observed from a viewer positioned in front of thefireplace 80 into whichflame projection device 10 is seated. Thehousing 20 may be made of any suitably rigid material, e.g., metal, plastic, poly-resin, wood, or engineered wood (MDF or particle board). In embodiments of theflame projection device 10 that include a hot air generator, for safety reasons, thehousing 20 is preferably made of a heat-resistant material such as metal. - The
interior compartment 28 is accessible through a relativelylarge opening 29 in the top of thehousing 20. Thelight source 30,spindle 32,reflectors 34, mechanical device for rotating thespindle 36,flame cutout panel 38, andhot air generator 40 can be accessible through theopening 29 and might be installed during the fabrication of theflame projection device 10 therethrough. As illustrated inFIG. 1 , thefront portion 23 ofhousing 20 might also include ascreen 42 through which heated air is passed through from thehot air generator 40. - The
simulated fuel source 50 can be installed on the top of thehousing 20 over theopening 29. Thesimulated fuel source 50 can be made from synthetic materials (e.g., plastic) to resemble the appearance of a traditional fuel source (e.g., wood or coal) or a series of stones. In some embodiments, thesimulated fuel source 50 includes a plurality of light transmitting portions (e.g., transparent or translucent regions) that allows light from a light such as thelight source 30 installed in thehousing 20 to illuminate the outer surface of thesimulated fuel source 50 in a pattern similar to a traditional fuel source (e.g., with several different regions having different light intensity which may follow the cracks and crevices of the simulated fuel source 50). - As illustrated in
FIG. 4 , thereflectors 34 of thespindle 32 may be shaped as finger-like projections. Thespindle 32 may be rotated by mechanical device for rotating thespindle 36. Thelight source 30 can be any suitable lighting device such as incandescent light bulbs, gas discharge lamps, or light emitting diodes (LEDs). Thelight source 30 is preferably selected to emit light of colors similar to those from a burning fuel source (e.g., reds, yellows, oranges, blues, and violets), although filters might be used for this purpose as well (e.g., to selectively transmit the reds, yellows, oranges, blues, and violets within a white light source). Where thelight source 30 includes LEDs, these LEDs may be located in different positions within thehousing 20, e.g., different sets of LEDs can be mounted in a straight line to direct light toward thespindle 32 andreflectors 34. - As shown in
FIGS. 4 and 5B , theflame cutout panel 38 can be interposed between thelight source 30 and theback wall 86 of thefirebox 84. Theflame cutout panel 38 can be made of a panel of light-blocking material having one or more portions therein cut out in the pattern of flames as shown inFIG. 4 . Theflame cutout panel 50 thus acts as a stencil that forms the light reflected of thespindle 36 intosimulated flames 33 before it hits theback wall 86 of thefirebox 84. - Referring to
FIGS. 5A and 5B , theflame projection device 10 can optionally include thehot air generator 40 within thehousing 20. Thehot air generator 40 preferably includes an electrically powered heating element and a blower fan. Thecontroller 70 may be used to adjust and control the temperature of the heated air that is generated as well as fan speed. A thermostat may be used to adjust and control the temperature of the heated air. Thehot air generator 40 as well as other components of theflame projection device 10 can be powered bypower source 60 which can take the form of a connection to any conventional power source (e.g., a household electrical source or battery). - The
controller 70, which can be used to control the operation of thelight source 30, may be any suitable controller such as, for example, a computer and software, an electric circuit, or one or more manual switches. Thecontroller 70 can also be used to control other features of the electric fireplace such as, for example, thehot air generator 40, a timer, an audio system and an on/off power switch. - In some embodiments, the
flame projection device 10 might also include an audio system for projecting sound that resembles the sound of actual burning wood. For example, crackling sounds that may be stored on a memory chip and emitted by an audio speaker on thehousing 20 to simulate the sparks and associated crackling noise of burning embers. - The
power source 60 can be any safe and suitable source of power such as for example, an electrical connection to a home's electrical system via connection to an outlet, or connection to one or more batteries. - As shown in
FIG. 2 , the screenlessflame projection device 10 might also be included in a kit that further features asimulated fireplace 80. Although thesimulated fireplace 80 might include afirebox 84 having aback wall 86 that is made of a material (such as a plastic screen) to enhance the appearance of thesimulated flames 33 projected thereon by theflame projection device 10, theflame projection device 10 is typically arranged to project simulated flames without requiring a screen, so that theback wall 86 can be fashioned to simulate the aesthetics of the back wall of a conventional fireplace firebox, e.g., simulated brick, stone, firebrick, antique brick, or painted concrete. - The invention also provides methods for simulating flames in a fireplace using a standalone screenless flame projection device such as described above.
