Definitions

  • a simulated fireplace assembly includes a housing having a fan located therein whose air flow axis is tilted upwardly, and a heating means.
  • Air deflecting baffle plates are provided to divert the air stream from the fan into two streams, one generally vertical and the other horizontal; the horizontal stream passes the heating means and thence through an air-permeable front panel of the housing to heat the surrounding space, while the vertical air stream exists through an airpermeable top panel of the housing to activate portions of a flame simulator associated with an ornamental display of at least one log supported on the top of the housing.
  • This invention relates to simulated fireplace assemblies, and more particularly to such an assembly which provides heat to the surrounding air space and at the same time creates a visual illusion of actual fire in and around the artificial logs displayed as part of the assembly.
  • Simulated or artificial fireplace assemblies are known in the industry. Such assemblies usually employ an electric heater and sometimes a fan blower to more efficiently dispense the hot air from heater elements to the surrounding room space. Often such fireplace assemblies are wall mounted, although they may be free standing; and artificial or imitation fire logs are included in the arrangement to give the visual illusion or appearance of an actual fireplace. Sometimes varied colored lights are added to further enhance the fire-like appearance of the entire arrangement. Indeed such cosmetic effects are believed to be as important, if not more important, than the heating capability of the unit itself. In fact, it is generally the case that simulated fireplace assemblies are utilized in rooms other than main rooms of a residence; for example, bedroom, dinette, den, or the like. Such artificial fireplace assemblies are also used in commercial establishments to enhance and give a pleasant atmosphere.
  • FIG. 1 is a perspective blow-up" of the entire simulated fireplace assembly embracing our invention
  • FIG. 2 is a side viw of an assembly utilizing our invention wherein the lower portion is shown as a partial section at about the transverse midplane, in order to more clearly reveal certain internal details;
  • FIG. 3 is an electrical schematic diagram showing one wiring arrangement that may be utilized in a simulated fireplace embracing our invention.
  • FIG. 1 There we illustrate'a simulated fireplace assembly at bracketed portion 12 including the ornamental display of artificial logs 14, 16 and 18 carried by grate assembly 20 having legs 21 which in turn rest upon upper exterior section 24 of housing assembly 22.
  • Upper exterior section 24 is of composite fabrication comprising cover 25a and an artificial hearth-like covering 25b; cover 25a is secured by sheet metal screws 25c to housing side flanges 25a.
  • the ornamental hearth covering 25b may merely slip over cover 25a and remain frictionally engaged therewith.
  • housing assembly 22 primarily forms the interior fan chamber 26 which houses therein fan assembly 28 and the support housing for heating means 30.
  • fan assembly 28 upon being appropriately installed and energized, causes air to be circulated from the fan chamber through and past the electrical heating coils of assembly 30, and thence into the ambient spaces surrounding the unit to provide warmth in 'a known manner associated with electrical heaterblower units.
  • baffle assembly 32 acting in cooperation with fan assembly 28, the use of open mesh, i.e., air-permeable, panel sections 34, 36 and ornamentation strips 38 which, in the embodiment shown, comprise thin and flexible reflective material, such as cellophane or the like, located in the air space between logs 18 and 16; and logs l6 and 14. More specifically, strips 38 are secured at their ends to and held in position by wire brackets 40, 42, which in turn are conventionally attached to grate end bars 44, 46 by means of opposing nut sets 40a, 42a.
  • Baffle assembly 32 comprises a shield of crosssectional shape and is mounted within housing 22 between heater assembly 30 and upper exterior section 24.
  • baffle 32 comprises a first planar section 48 transverse to the interior cavity of housing 22, i.e., co-extensive with the area bounded by heater assembly 30, inner side walls 56a and 56b of the housing, and upper exterior section 24; a second planar section 50 which overlays heater assembly 30; and a third planar section 52 which is in generally normal alignment with the air-permeable front panel 34.
  • an air stream is caused to flow as indicated by arrows 54a and 54b (FIG. 2). That is the portion of the air stream represented by arrows 54a is deflected by baffle assembly 32 so as to pass through and contact heater coils 30a, become warmed thereby, and thence pass outwardly through air-permeable panel 34 into the air space thereabout to be heated.
  • a particularly beneficial feature of our invention is that the foregoing combined function of blowing heated air and wafting cellophane strips 38 to create an illusion of flame flickers is achieved by a single fan assembly 28. In this way, significant economies in the overall preparation and fabrication of devices embracing our invention are achieved. More specifically we preferably achieve this salutary feature by the arrangement wherein fan chamber 26 is defined in part by a generally vertical wall portion 56 adjoining upper exterior section 24. Further,wall portion 56 having lip 56a and cover panel a having vertical flange 25e are assembled to form an overlapped corner edge 58 (FIG. 2).
  • baffle panel 48 is fabricated to form a transverse section which slopes upwardly from heater assembly with upper edge 60 thereof in common contact, or very nearly so, with the common edge of cover panel 25a and flange 25e along corner edge 58.
  • fan assembly 28 which in the embodiment shown comprises electric motor and housing case and fan propeller 28b is mounted within fan chamber 26 so that the rotational axis 62 of the fan propeller substantially lies in the plane which bisects interior angle 64 defined by plane of wall portion 56 and baffle panel 48.
  • the air stream established by rotation of fan 28b is divided into the two streams indicated, respectively, by arrows 54a and 54b; portion 54a being deflected by baffle assembly 32 past heater assembly 30, as explained hereinabove, and portion 54b upwardly through airpermeable panel 36 thence to waft cellophane strips 38.
  • portion 54a being deflected by baffle assembly 32 past heater assembly 30, as explained hereinabove, and portion 54b upwardly through airpermeable panel 36 thence to waft cellophane strips 38.
  • motor assembly 28 is mounted so that the transverse plane thereof is inclined at angle 66 of about 17 from the vertical. Using such values, and with the fan rotational axis very nearly directed 'through corner edge 58 we have achieved excellent blower and flame illusion results.
  • motor assembly 28 may be mounted in any conventional manner. Such techniques are well known to those of ordinary skill in the art and are not shown in the accompanying drawing nor described herein.
  • baffle plate 48 with respect to its slope angle from heater assembly 30, other arrangements at or near such angle will function in accordance with the present invention.
  • the particular slope of the fan assembly axis may be varied somewhat, although we prefer the results achieved when the transverse plane angle 66 is at or about 17.
  • the general illusion of flame flicker and presence described hereinabove with respect to cellophane strips 38 may be further enhanced by the use of independent light sources therefore, especially when such sources are of various colors. This may be achieved in accordance with the present invention by the use of light bulbs 68 operatively mounted in appropriately wired receptacles 68a (FIG. 2).
  • cellophane strips 38 may be cut to have a scallop-like shape resembling the flame elements of an actual fire. Thereupon when the strips are made to quiver by the air currents from fan assembly 28, the combination of reflected color lighting from sources 68 and moving strips 38 coact to produce an even more convincing illusion of an actual fireplace fire. The entire effect is even more accentuated when the room in which our invention is placed is otherwise darkened.
  • FIG. 3 Main power, such as ordinary 110 VAC. current, is introduced at a main plug 70 and one conductor thereofis connected to one terminal ofa single pole switch 72 located at the side of housing 22 (FIG. 1). The other conductor of the main power line is connected to one terminal of electric motor 28a; one terminal of an auxiliary power plug 74 to be used to energize light sources 68; and one terminal of heater coil elements 30a, the entire bank of elements being connected in parallel.
  • the other terminal of the aforementioned single pole switch 72 is connected to one terminal of thermostat 76; the second terminal of motor 28a; and the second terminal of receptacle 74.
  • Thermostat 76 in turn is connected in series with thermodisc 78 and thence to the second terminal of the parallel heater elements 39 11.
  • the heater elements may be controlled for temperature by manual adjustment and a pre-determined temperature safety cut-off setting.
  • an artificial coal bed 80 may be added and placed atop hearth cover 25b beneath the realistic grate assembly 20.
  • baffle assembly 32 as fabricated of two sheet metal sections screwed together, although a single piece of metal properly formed could be used.
  • resister-heater elements 30a are shown mounted in one conventional manner known to those skilled in the art and have not further described nor specified herein, although other means and techniques could be used therefore.
  • artificial logs 14, 16 and 18 are fabricated of a particularly light plastic material and in the embodiment shown are hollowed out, thus forming a convenient and useful place to mount light sources 68.
  • Other materials could be used even actual logs and the light sources placed in other locations hidden from direct view by occupants where our elegant and useful invention adorns the premises.
