Definitions

  • This invention is related to flame simulating assemblies.
  • One type of known flame simulating assembly typically includes a simulated fuel bed, one or more light sources, a screen disposed behind the simulated fuel bed for diffusing and transmitting light from the light source, and a flicker element for causing light from the light source to fluctuate, or flicker to simulate flames. Images of flames are provided by fluctuating light from the light source which is transmitted through the screen.
  • the known electric flame simulating assembly also includes a flame effect element which configures fluctuating light from the light source to form the images of flames which are transmitted through the screen.
  • An example of this type of flame simulating assembly is disclosed in U.S. Patent No. 5,642,580 (Hess et al).
  • an artificial fire unit which includes a television set and a video recorder for playing recordings of fires on the television set
  • the artificial fire unit is positioned in a cabinet so that it appears to be "a conventional domestic fire unit" (p. 2, at lines 19 - 20).
  • the typical flame simulating assembly is sold with a trim package according to the purchaser's preference.
  • most flame simulating assemblies are sold with a trim package which, upon assembly, resembles a natural fireplace hearth and mantel and associated woodwork.
  • flame simulating assemblies positioned inside simulated stoves e.g. cabinets which resemble wood-burning stoves
  • a flame simulating assembly includes a device for simulating flames, regardless of whether, for example, the device is installed in a simulated stove or fireplace
  • a flame simulating assembly 20 of the prior art includes a housing 22, a screen 24, and a simulated fuel bed 26 positioned in the housing 22, in front of the screen 24.
  • the housing 22, the screen 24, and the simulated fuel bed 26 define an internal chamber 28, through which air is drawn by a fan 30.
  • the flame simulating assembly 20 also includes a heater with one or more heating elements 32.
  • a front part 34 of the housing 22 includes holes 36 to permit air which has been warmed by the heating elements 32 to exit into the premises in which the flame simulating assembly 20 is located, as schematically indicated by arrows 38 in Fig. 1.
  • holes 40 may be located in a bottom wall 42 of the housing 22 so that air is drawn through the holes 40 by the fan 30 from outside the chamber 28 (as schematically indicated by arrow 44) through the chamber 28 (as schematically indicated by arrows 46, 48).
  • intake holes 40 are sometimes located in side panels of the housing (not shown) in prior art flame simulating assemblies, or in other parts of the housing 22.
  • the flame simulating assembly 20 illustrated is the type of flame simulating assembly described in U.S. Patent No. 5,642,580 (Hess et al.), referred to above.
  • the flame simulating assembly 20 has a flame image subassembly 50 which includes the simulated fuel bed 26, the screen 24 positioned behind the simulated fuel bed 26, one or more light sources 52, a flicker element 54, and a flame effect element 56.
  • the flame image subassembly 50 may include a variety of components in various configurations, and is adapted to provide one or more images of flames on the screen 24, so that the images of flames appear to be ezoanating from the simulated fuel bed 26.
  • the holes 40 are usually located in the vicinity of the light source 52, so that heat generated by the light source 52 is drawn away and dissipated by the air flow through the holes 40 towards the holes 36, which air flow is generated by the fan 30.
  • known flame simulating assemblies do not include air filtration systems.
  • known flame simulating assemblies are not of airtight (whether substantially airtight or otherwise) construction, so ambient air enters into the internal chamber through many cracks, holes, and small openings in the housing, and, for example, between the screen and the housing, between the screen and the simulated fuel bed, and between the simulated fuel bed and the housing.
  • airborne contaminants such as dust and other materials (i.e., not only particles) which are in the ambient air are drawn into the internal chamber 28, and then sent back out into the premises without any filtration.
  • dust accumulates in the internal chamber.
  • the air which exits the chamber 28 through the holes 36 therefore typically includes as much dust as the ambient air, and can include more on occasion if, for example, some of the dust in the chamber is picked up by the air flow through the chamber.
  • Filtering the air drawn through the intake holes 40 is somewhat difficult, as the holes 40 are relatively small, even when considered in the aggregate, in general, in order to ensure that smaller particles are caught in an air filter, the filter typically has relatively small holes in it.
  • a relatively high pressure differential across the air filter is required to draw the air through the filter.
  • a fan capable of providing the relatively high volume required and a relatively high pressure differential is relatively expensive.
  • known flame simulating assemblies are not of airtight construction, known filtering systems are of limited effectiveness.

  • the screen, the housing and the simulated fuel bed delimit an internal chamber.
  • the flame simulating assembly also includes a fan positioned to provide an air flow through the internal chamber from one or more intake apertures, through which air is drawn into the internal chamber, to one or more exit apertures, through which the air in the air flow exits the internal chamber.
  • the flame simulating assembly includes one or more air filters for filtering at least a portion of the air in the air flow, the air filter being positioned to filter contaminants out of the air in the air flow.
  • the internal chamber is substantially airtight, except for the intake and exit apertures.
  • the flame simulating assembly additionally includes one or more heating elements for heating the air in the air flow.
  • the invention also includes a thermal switch positioned proximal to the heating elements.
  • the thermal switch is adapted to cause one or more alerting devices to be energized upon the thermal switch reaching a predetermined temperature.
  • the increase in the temperature of the air surrounding the thermal switch up to the predetermined temperature (and beyond) results from at least partial obstruction of the air filter.
  • the alerting device is an electric lamp.
  • the invention provides intake apertures disposed in the back panel, and the air filter is positioned adjacent to the intake apertures.
  • the invention additionally includes a mantel portion positionable substantially above the air filter, the mantel portion being movable to provide access to the air filter for removal thereof
  • the housing includes a bottom panel connecting the side panels and the back panel, and the intake aperture(s) is (or are) positioned in the bottom panel.
  • the air filter is positioned adjacent to the intake aperture(s).
  • the invention additionally includes a front exterior portion positionable in front of the air filter, the front exterior portion being removable to provide access to the air filter for removal thereof
  • the invention includes one or more electric lamps, and a control device operatively connected to the lamp(s) for activating and de-activating the lamp(s).
  • the control device includes one or more sensors for sensing a temperature of the air in the air flow.
  • the invention also includes a control circuit operatively connecting the sensor to the lamp for activating the lamp when the temperature of the air is at a predetermined temperature or higher. The sensor is positioned proximal to the heating element so that when the air filter is obstructed to a predetermined extent, the lamp is energized, indicating that the air filter is due for replacement.

  • the air flow generated by the fan 130 results in the air in the air flow exiting the chamber 128 through exit apertures 136, as represented schematically by arrows 137.
  • the air filter 160 is for removing contaminants in the air flow from the air.
  • more than one air filter may be used together.
  • a charcoal filter for odors
  • pre-filter to remove larger particles

  • air filtration systems can include chemical and other systems for filtering air, as well as particulate filtration systems.
  • references to the "air filter” will be understood to include a single filter and any of the foregoing types of air filtration systems.
  • the housing is preferably constructed of panels of sheet metal which are fastened together using any suitable means.
  • the housing is used to form part of a plenum (i.e., the internal chamber 128), the housing is manufaactured to be substantially airtight (i.e.. except for the intake and exit apertures), at least in the portions of the housing which delimit part of the internal chamber 128.
  • the other components of the flame simulating assembly 120 which also delimit the internal chamber 128, i.e., the screen 124 and the simulated fuel bed 126, are preferably mounted in the housing 122 so that substantially airtight seals are formed between the housing, the screen 124 and the simulated fuel bed 126.
  • Such sealing can be effected by any suitable means, including caulking with a suitable sealant, or using gaskets.

  • some leakage around the sealing elements can be permitted, for acceptable functioning of the filtering system.

  • the air filter 160 (i.e., the operational area of the filter) is as large as possible, in order to facilitate efficient filtering of the air which passes through the filter 160. Because the filter 160 covers a relatively large area, the filter 160 can have a plurality of relatively small holes in it through which the air is drawn, however, with a relatively low pressure gradient across the filter 160.
  • the air filter 160 is preferably a standard size particle filtering system, such as a filter 20 inches in height by approximately 20 inches in width by approximately one inch in thickness.
  • the air filter 160 is an electrostatically charged filter, because an electrostatically charged filter operating with a relatively lower pressure drop across the filter is nevertheless generally as effective as a non-electrostatic filter operating with a higher pressure drop across it.
  • the holes in the air filter 160 are relatively small, so that the filter can accumulate relatively small particulates.
  • the intake apertures 140 are preferably distributed over an area of the back panel 127 which has approximately the same dimensions overall as the operative part of the air filter 160.
  • the filter 160 tends to become obstructed after usage over a period of time, as particulates accumulate on the filter 160 and gradually build up to obstruct or close the holes in the filter 160. Because of this, the filter 160 has to be removed from the flame simulating assembly 120 from time to time, for maintenance. For example, depending on the type of filter, the air filter may be replaced by a new air filter. However, if the air filter is of a type which is to be cleaned, rather than replaced, then the air filter is cleaned.
  • the flame simulating assembly 120 preferably includes a thermal switch (or control device) 162 (Fig. 5) positioned proximal to the heating element 132 (Fig. 3).

  • the thermal switch (or control device) 162 includes one or more sensors for sensing (i.e., measuring) a temperature of the air in the air flow as the air exits the heating elements 132.
  • the control circuit 166 operatively connects the sensors to the lamp for activating the lamp 164 when the measured temperature of the air in the air flow is at the predetermined temperature, or at a temperature greater than the predetermined temperature.
  • the rate of flow of the air through the heating elements 132 decreases.
  • the temperature of the air exiting the heating elements 132 quickly rises, becoming much hotter than the temperature of the air exiting the heating elements 132 under normal operating conditions.
  • the thermal switch 162 which (in the preferred, embodiment) is normally open, closes when the predetermined temperature is reached, thereby completing the control circuit 166, and causing current to flow through the electric lamp 164. As is known in the art, the thermal switch remains closed until a reset button .is operated, regardless of the temperature of the air in the air flow after the thermal switch has closed.
  • the electric lamp 164 preferably is mounted in a position where it is easily viewed by a user (not shown), such as in a control panel (not shown) mounted on the flame simulating assembly. Accordingly, upon activation of the electric lamp 164, the user is thereby alerted that the air filter 160 should be replaced. It will be appreciated that, instead of the electric lamp 164, any other suitable alerting device, such as a device for emitting an audible warning, could be used.

  • the frame 361 preferably extends below the bottom panel 342 because it is necessary to allow space inside the flame simulating assembly 320 for components of a flame image subassembly 350 (i.e., a light source 352) above the bottom panel 342 and below a screen 324 and a simulated ember bed 326.
  • a flame image subassembly 350 i.e., a light source 352
  • the flame simulating assembly 320 includes a housing 322 which includes the bottom panel 342, a back panel 327 extending upwardly from the bottom panel 342, side panels 325 (Fig. 10) connected to each other by the bottom panel 342 and the back wall 327, a top panel 323 at the top of the side panels 325, and one or more front parts 334 positioned opposite to the back panel 327.
  • the front parts 334 include a lower front part 370 positioned proximal to the bottom panel 342 and an upper front part 371 positioned proximal to the top panel 323.
  • An internal chamber 328 is delimited by the housing 322, the screen 324, and the simulated fuel bed 326.
  • the housing 322 also preferably includes feet 368 to support the bottom panel 342 above the floor (not shown), so that ambient air can flow into the internal chamber 328 from the premises.
  • the bottom panel 342 has one or more intake apertures 340 positioned in it through which air is drawn by a fan 330 from the premises in which the flame simulating assembly 320 is located (schematically represented by arrows 331).
  • the frame 361 for the filter 360 can be positioned substantially in an aperture 340 in the bottom panel 342.
  • the fan 330 also drawn the air through the internal chamber 328 (as represented by arrows 333, 335) towards the fan 330, and the air is subsequently pushed by the fan 330 through exit apertures 336 out of the internal chamber 328.
  • the air filter frame 361 preferably extends to the lower front part 370. Preferably, this permits relatively easy removal of the air filter 360 from the frame 361, by sliding the filter 360 fornvardly (i.e., in the direction of arrow "A" in Fig. 8).
  • the filter 360 can be placed in the frame 361 by pushing the filter backwardly (i.e., in the direction of arrow "B" in Fig. 8).
  • the filter 360 is preferably securely positioned in the frame 361 by a latching mechanism or any other suitable mechanism, as is known in the art.
  • the frame 361 is also shown in Fig. 11 to extend to the front panel 371.
  • arrows "A" and “B” are also shown in Fig. 11, to indicate the direction in which the filter 360 is moved when it is to be removed and the direction in which the filter 360 is moved when it is to be installed, respectively.
  • the access from the front which is provided in the flame simulating assembly 320 is generally more convenient than the access to the filter which is provided in the embodiments of the flame simulating assembly (120, 220) in which the air filter (160, 260) is mounted on the back panel (127, 227).
  • the air filter 360 is generally not as large as the air filter which is positioned in the back panel
  • the bottom-mounted filter is typically a size such as approximately 20 inches by approximately 10 inches by 1 inch which is standard, and readily available from a variety of manufacturers.
  • a larger operative area of an air filter is generally advantageous because a relatively large air flow volume can be provided through relatively small holes in the filter with a relatively low pressure differential across the filter.
  • access to the bottom-mounted filter is relatively convenient
  • a flame simulating assembly 420 includes a bottom-mounted filter 460 and a flame image subassembly 450 similar to the flame image subassembly 250.
  • the flame image subassembly 450 includes a flame effect element 456 with a reflective portion 459 shaped to resemble flames, similar to the flame effect element 256 shown in Fig. 6.
  • a front elevation view of the flame simulating assembly 420 also would be as shown in Fig. 10.
  • Fig. 10 is an illustration of a front elevation view of the flame simulating assembly 320 also shown in Fig. 8.
  • a bottom elevation view of the flame simulating assembly 420 would be as shown in Fig. 11.
  • FIG. 12 Another alternative embodiment 520 of a flame simulating assembly is shown in Figs. 12 -16.
  • the flame simulating assembly 520 includes an exterior subassembly 572 enclosing at least a portion of a housing 522 and generally including a mantel portion 574, a front portion 578, and side walls 580 (Figs. 14, 15).
  • the flame simulating assembly 520 also includes a bottom portion 581 (Fig. 12).
  • the exterior subassembly 572 comprises a "trim" package resembling a mantel and other decorative parts of an actual fireplace, which is provided to enhance the simulation effect of the flame simulating assembly.
  • the exterior subassembly 572 can be made of wood, wood veneer, or any other suitable material, and provided with a suitable finish.
  • the exterior subassembly 572 does not include a back wall, unless needed in a particular application.
  • the mantel portion 574 is movable relative to the housing 522 between a closed position (Fig. 12), in which an air filter 560 is inaccessible because it is covered by the mantel portion 574, and an open position (Figs. 13 - 16), in which the air filter 560 is accessible because the mantel portion 574 has been moved forwardly.
  • a closed position Fig. 12
  • an open position Figs. 13 - 16
  • the air filter 560 is accessible because the mantel portion 574 has been moved forwardly.
