Definitions

  • This invention relates to apparatus for simulating flames in a solid fuel fire.
  • a simulated solid fuel fire may be part of, or embodied in a heating appliance, such as an electric or gas fire, in order to create an impression of flames due to burning fuel.
  • the simulated flame effect was created by a plurality of ribbons made of fabric which reflected light and which tended to undulate in an air stream, provided by a fan, so as to provide a constantly changing reflecting surface similar to the appearance of flames.
  • This apparatus provided considerably more realism due to the capability of the screen to reflect light from the simulated fuel, whereby the simulated flames appeared to emanate from between the fuel and its image in the screen. This was a considerable improvement over earlier attempts such as those described in, for example, GB-A-957 591, 978 365 and 1 186 655, which disclosed the use of ribbons for simulating flames on a screen, but not the use of a screen capable of reflecting light in the manner mentioned above.
  • a further disadvantage was due to using e.g. white fabric ribbons suspended against a totally non-reflective or dark background (i.e. to heighten the reflectivity of the ribbons).
  • the totally dark or non-reflective background absorbed light, hence giving a rather dull display which is difficult to perceive in strong ambient lighting.
  • the present invention seeks to address these problems and to provide considerably more realism, especially where it is necessary to simulate flames emanating from simulated fuel.
  • GB-A-1 088 577 mentions (as prior art) a radiant electric fire which utilises a series of ribbons which move in a current of air from a fan.
  • the reference states that coloured light is projected i.e. reflected from behind the ribbons so that the latter provide a series of moving shadows on a screen which forms the fire back above the imitation fuel and that such an effect is more realistic but expensive to produce.
  • coloured light is projected onto a reflector and then reflected onto ribbons, this will cause cast shadows against the colour of the projection light. Consequently, the simulation of flames is not as realistic as it could be.
  • the reference itself seeks to address the problem by producing a fire which may include ribbons of at least two different colours, such as red and yellow, so that movement of the ribbons provides a flickering shifting colour pattern on the screen. More specifically, the reference discloses a casing having an interior metallised or painted surface to act as a reflector whereby light is reflected from the interior face of the back panel of the casing, through the coloured ribbons, and whilst this may produce a reasonably satisfactory effect, at less cost, it is still not an optimum effect.
  • GB-A-1 272 644 discloses an alternative way of trying to introduce colour into apparatus for producing imitation fire effects.
  • a reflective paddle wheel which is rotated by a motor, reflects light onto the rear of a screen or screens having an etched or frosted pattern, representing an artistic design which diffuses or reflects light rays emanating from a light source.
  • a reflective surface which is concave about a horizontal axis, is positioned behind the reflecting panels and screen.
  • the reflecting paddles, reflector and light source are coloured to produce coloured flames against a red background to simulate a fire effect. Whilst this again may produce a reasonably satisfactory result, it is not an optimum effect.
  • the present invention greatly enhances the simulated flame effect and can create almost the same impression as a real flame.
  • apparatus for simulating flames in a solid fuel fire comprises: rear reflector means; means for simulating flames including a member or members and means for causing said member or members to move so as to simulate flames; a screen capable of diffusely transmitting light, said member or members being positioned between the rear reflecting means and the screen; simulated fuel positioned in front of the screen; and means for illuminating said simulated fuel, said member or members, and said rear reflecting means; said screen also being capable of reflecting light so that a reflected image of the fuel is visible in the screen; said illuminating means including a source of light which is randomly intercepted by movement of said member or members; said rear reflecting means including reflecting regions situated below a darkened or blackened area which reflect said light in such a way as to cause a perception of colours; the arrangement being such that luminous flame-shaped images, tinged with colour, can be perceived between shadows on the screen, said flame-shaped images appearing to emanate from between the simulated fuel and its image on the screen
  • the rear reflecting means is concave about a vertical axis and the member is a flag-like member located centrally of the concave reflecting means.
  • the rear reflector means may be a curved sheet on which the reflecting regions are defined by a lower edge of the darkened or blacked area, which lower edge has inverted U-shaped portions.
  • Such an arrangement enables, for example, a single flag-like member to replace a plurality of parallel ribbons as used in the prior art mentioned above.
  • the blacked or darkened area tends to heighten the luminous appearance of the flame-shaped images, which are due to reflection of light from the rear reflecting regions.
  • substantially white light is used to illuminate the reflecting surface which thereby reflects the white light in such a way as to cause a perception of colours.
  • This effect may be provided by a metallised film or foil, having a reflective surface which diffracts or refracts white light in such a way as to enable the different colours to be perceived.
  • This reflecting surface can be positioned either adjacent, or in contact with a lower portion of the front surface of the rear reflector means.
  • a single flag-like member may intercept the light reflected from the rear reflector means onto the screen.
  • This material may be cut or shaped to assist in producing an impression of flames, and preferably contains a slit and an aperture.
  • the member may be generally coffin-shaped and have a slit, as well as a diamond-shaped aperture therein.
  • the flag-like member is preferably draped across an air outlet of a fan, so that it moves in an airstream from the fan, thereby intercepting the white light in a random fashion to cause the flame shaped images to be cast onto the screen.
  • a bulb or bulbs may be situated at the side or sides of the flag-like member and positioned to give optimum shadows and patches of light on the screen, i.e. to give a good impression of flames.
  • means are included for simulating sparks in the simulated flames.
  • the means for simulating sparks may comprise a piece of reflective metallised plastics film or foil having portions which move in the airstream and thereby reflect flashes of light onto the screen. This film or foil is positioned in the airstream from the fan and may be mounted independently of the flag-like member, or be attached to it.
  • the front surface of the screen is preferably coated or treated so as to reflect light, the coating enabling light to be transmitted through the screen.
  • This reflective coating provides a strong reflection of the simulated fuel to enhance the overall effect.
  • the simulated fuel, especially logs may also receive light cast downwardly from above, so that a corresponding reflected image of the fuel (e.g. log) can be clearly seen in the screen, thereby promoting realism.
  • the screen can alternatively include a transparent or translucent panel or panels, the front surface of the panel or leading panel reflecting light either due to a coating, or an inherent property of the panel. Such arrangements, however, do not give the optimum effect due to poorer reflection.
  • An additional panel may be fitted at the front which is capable of transmitting light, to enable the simulated flames to be perceived on the screen, whilst being tinted sufficiently so that components behind this additional panel are at least partly, if not wholly obscured when the source of illumination is switched off.
  • apparatus for simulating flames in a solid fuel fire comprises: simulated fuel; means for simulating flames including a fan and a member shaped and movable in an airstream from the fan so as to simulate flames; means for illuminating the simulated fuel and said member; and a screen positioned between the simulated fuel and said member, the screen being capable of both diffusely transmitting and reflecting light, whereby simulated flames are visible on the screen, which flames appear to emanate from between the simulated fuel and its reflected image in the screen; the apparatus further including rear reflecting means which are substantially concave about a vertical axis; said member being a flag-like piece of material located centrally in front of the rear concave reflecting means and shaped and positioned so that it randomly intercepts the light which illuminates the rear reflecting means, whereby the simulated flames are perceived at different positions along the width of the screen.
  • the concave reflecting means may include reflecting the regions situated below a darkened or blackened area, and also a reflective surface which reflects, e.g. substantially white light in such a way as to cause a perception of colours, the arrangement being such that luminous flame-shaped images, tinged with colour, can be perceived between shadows on the screen.
  • an electrical fire comprises a casing 1 and a front facia 2 which is secured to the casing (as shown in Fig. 2).
  • the components described below are located within the casing or adjacent the fascia.
  • a curved rear reflector 3 which can be made of metal (such as aluminium), having a polished front surface, preferably has selective regions 4 darkened or blackened by a suitable coating or layer of material. These regions 4 have a somewhat random pattern but generally exist at the top of the reflector and have lower edges defining inverted U-shaped portions 5. Portions 5 are not darkened or blackened and they present a fully reflective surface. However, coloured light producing means 6, preferably in the form of a sheet, is adhered, attached, or positioned adjacent a lower region of the rear reflector 3. These means 6 have a surface which reflects (e.g. substantially white) light but also causes the incident light to be separated into some of its constituent colours.
  • This effect is comparable with selective diffraction or refraction of white light by e.g. prisms or optical gratings, whereby rays of light, having different optical frequencies, are bent through different angles, hence being perceived as colours (such as red, yellow, blue etc.).
  • Various components and/or materials may be used to produce this effect, but we have found the use of thin metallised plastics or foil, having certain optical reflecting properties, to be particularly useful.
  • Such foil is similar to that which is sometimes used for gift wrapping and it has the property of reflecting ambient light but tinged with various colours, depending on the angle from which it is viewed. In some respects, this is similar to the effect produced by a thin film of, e.g. petrol on water in which multi-coloured or rainbow effects can be seen.
  • the material we used was manufactured by the Cobourn Corporation, in the USA or Germany, and this either has a plain finish, giving the impression of a pearly metallic surface on which there are very fine lines, or a pearly surface on which there is a regular etched pattern, somewhat resembling facets of a crystal.
  • a pearly metallic surface on which there are very fine lines or a pearly surface on which there is a regular etched pattern, somewhat resembling facets of a crystal.
  • one sample was known as a "1/4 inch mosaic diffraction prismatic" pattern called “Diffractolite”.
  • An alternative material, available from the same Company is called “Holographic Crystal”.
  • a further alternative, made by Markem Systems Limited, has a "Holofoil” pattern.
  • Such materials generally include a plastics metallised film (e.g.
  • aluminium which is patterned by etched steel rollers, on a PE carrier, and which may be treated in some way so as to cause the required diffractions of refractions which result in reflections of coloured light.
  • its reflective, colour generating surface is the front surface of means 6, i.e. facing outwardly towards the fire opening.
  • its upper edge preferably resembles a pattern of flames (as see, for example, on burning fuel).
  • holographic Materials having so-called "holographic" properties may be similar to photographic materials in which the surface of a substrate is covered with lenticular strips which have the effect of diffracting light. These strips may be of various cross-sections, e.g. triangular, and they extend in a direction so that light received, from a certain angle of incidence, is subject to a diffraction effect.
  • Other holographic materials may be used including, for example, films produced by holographic techniques and/or substrates coated with materials, or used in conjunction with films, having the same effect.
  • a diffusing screen 7 may include one or more panels, which are translucent or transparent, and which have the effect of diffusely transmitting light received from the reflector 3 and also of reflecting light from the front surface of the (leading) panel.
  • panel 8 is a sheet of glass with a front surface (i.e. facing the facia 2) which is capable of reflecting light from an illuminated fuel effect 9 immediately in front of panel 8.
  • the simulated fuel may be in the form of a moulding, which is made of transparent or translucent material, and which is shaped, configured and decorated, e.g. with paint finishes, to resemble logs or coal.
  • the simulated fuel moulding 9 is situated above a chamber or light box in which bulbs 10,11 are mounted.
  • the front reflective surface of panel 8 is capable of reflecting an image of the fuel so that there appears to be a more extensive fuel bed when the fire is viewed from the front.
  • the simulated flames (described below) then appear to emanate from between the fuel and its reflection in the screen 7.
  • the front surface of panel 8 includes a coating which reflects light, but is thin enough to enable light to be transmitted through panel 8, from the direction of reflector 4.
  • Such a coating improves the reflection of the fuel in the screen 7.
  • panel 8 may be made of transparent or translucent material which is either tinted, or made in such a way that the front surface is capable of reflecting an image of the illuminated fuel 9.
  • a separate diffusing sheet 12 is located behind panel 8.
  • the main function of this component is to diffuse light received from reflector 4. It may be a translucent sheet (e.g. of glass) or it may be a sheet of thin material having light diffusing properties. Alternatively, the rear surface of panel 8 may be coated with material, or abraded, or etched, or otherwise treated so as to diffuse light. A diffusing sheet could also be adhered to the rear surface of panel 8.
  • a front panel 13 which is preferably made of tinted glass. This panel is transparent so as to enable simulated flames to be seen on screen 7.
  • the degree of tinting of panel 13 may be such as to obscure the interior of the fire when the bulbs 10,11 and, an optional bulb 14, are switched off.
  • Bulb 14 is located on casing 1 above a hole (not shown) in the casing, so that substantially white light is cast downwardly onto the upper surface of simulated fuel 9.
  • the fuel resembles logs and the purpose of bulb 14 is to illuminate painted surfaces of the imitation logs, and thereby to promote realism. Reflections of these illuminated surfaces are more easily perceived in the screen 7 in promoting such realism.
  • bulb 14 is optional and it is not required when the fuel resembles coal.
  • the front panel 13 can alternatively be lightly tinted, without necessarily obscuring the interior of the fire when the bulbs are switched off.
  • panel 13 It would also possible to have a coating on panel 13, e.g. on its rear surface, which is capable of reflecting light, but is thin enough to transmit light. Whether or not the rear surface of the panel 13 is coated in this way, or is reflective due to its inherent nature (its tinting), certain arrangements of the fire could be made to enable at least a second image of the fuel 9 to be perceived from the front of the fire.
  • This second image represents light reflected from fuel 9 onto the rear surface of panel 13, and then onto the front panel of screen 7.
  • a first image of the fuel 9 is reflected directly by the front surface of screen 7.
  • the effect is to produce the second image behind the first image and hence the illusion of a more extensive fuel bed.
  • this multiple image effect may not be required and panel 13 may not be capable of producing this second image.
  • bulbs 10 and 11 are situated one on each side of a reflective "flag" 17.
  • This flag is mounted so that it drapes across the outlet 15 of an electrically driven fan 16.
  • the outlet 15 is in the form of a slot in order to blow a curtain of air upwardly onto the flag 17.
  • the lower end 17a of the flag is attached to bulb mounting bracket 18, and at its upper end 17b is attached to the upper edge of reflector 3.
  • the flag 17 tends to fall into a loose curve because it is made of very thin (but strong) material.
  • the flag 17 is generally coffin-shaped with a diamond-shaped hole 19 in its lower portion.
  • the upper portion is in the form of two arms 20a,20b separated by a slit 21.
  • flag 17 As shown in Fig. 1, small slits are provided in the upper and lower edges of flag 17 for the purpose of attachment to bracket 18 and reflector 3 respectively.
  • the material of the flag 17 is preferably opaque and it may be coloured, e.g. ruby red. This material needs to be strong and thin and it is selected, with regard to the shape of flag 17 and the way it drapes (when the fan is off), and with regard to the performance of fan 16, so that the flag 17 ripples, flutters or undulates in the air stream and creates a continuously moving surface which intercepts substantially white light reflected by the rear reflector 3 from bulbs 10,11.
  • a reflective member 22 is provided in the form of a strip having arms at one end. This strip is used to simulate a spark effect, i.e. when sparks are occasionally seen to be generated in combusting fuel.
  • the strip 22 is made of reflective metallised film or foil and it has a blank end secured to the bulb bracket 18 as shown in Fig. 2. The other end may be made in the form of a comb, i.e. teeth separated by slits.
  • the member 22 is normally so flimsy that it hangs over the outlet 15 of fan 16. However, when the fan is switched on, the stream of air carries the teeth upwardly so that they flutter within the diamond-shaped hole in flag 17.
  • the effect of this is to cast occasionally flashes of light onto the screen 7 and these are perceived in the manner of sparks. These flashes of light are received directly by screen 7 from member 22, but some reflections may be received indirectly from reflector 3 which are less distinct but occur in different places.
  • the strip 22 may alternatively be attached to, or form part of the flag 17.
  • Fig. 2 the screen (8,12), fuel (9) and front panel (13) are still shown in exploded form, but they would be fitted so that the diffusing sheet 12 touches panel 8 and form a screen (7) which abuts the vertical front edges of the curved reflector 3.
  • the fuel moulding 9 would form a cover for bulbs 10 and 11 and its rear edge would be in contact with the screen 7.
  • the front panel 13 would contact the front edge of the fuel moulding 9 and be almost flush with the fascia 2.
  • imitation logs 9a,9b are made in the form of, e.g. a GRP moulding.
  • These first images are represented as 9a′ and 9b′.
  • the bulbs 10,11 and the optional bulb 24 are bulbs which emit what may be generally called "white” light.
  • Bulb 24 casts light onto the top of the imitation logs. These bulbs may be ordinary clear or translucent bulbs which would emit less than pure white light. However, the light emitted from the bulbs is diffracted or refracted into different colours by the effect of member 6. Bulbs of different tints could be used to create unusual effects, or different effects to those produced by using clear or white bulbs.
