Means (18) is provided to cause the sheet (14) to move, specifically by directing a flow of air upwardly against the material, to cause the material to billow. Light is directed from a light source (28) against the flame effect means, some light being reflected from the flame effect means directly through a translucent screen (24), some light passing through openings (20) of the sheet (14) onto a reflector (32), and being reflected from the reflector back through the sheet (14), and through the screen (24).
Description
- This invention relates to space heaters, and particularly but not exclusively to apparatus for simulating flames in a solid fuel effect fire, to give the impression of flames emanating from combusting fuel.
- A conventional space heater, herein referred to as being of the kind specified, comprises a housing, heating means in the housing, a flame effect means in the housing, a source of light to illuminate the flame effect means in the housing, and a screen through which light is transmitted from the housing. Frequently a means is provided, such as by a fan or mechanical means, to cause the flame effect means to move in the housing, and frequently the screen is translucent, to make the visual effect produced within the housing somewhat diffuse.
- Several arrangements have been used in the past to simulate flames in apparatus of the kind specified. For example, in GB-A-968568, there is shown an apparatus in which the flame effect means comprises a plurality of reflective ribbons suspended adjacent to a rear part of the fire, the light source being located forwardly of the ribbons, with a translucent screen also being located forwardly of the ribbons, such that light from the light source reflected from the ribbons is incident on a rear face of the screen, giving a flame effect when the screen is viewed from the front.
- As another example, it is known from GB-A-1186655 to suspend the ribbons in front of the light source, so that light is transmitted between the strips directly onto the translucent screen.
- In the specification of our European patent specification EP 0986722-A, the flame effect means is in the form of a sheet of translucent material, such as crepe-de-chine, which is provided with a plurality of vertically-extending elongate slits, the material being located optically between the light source and the screen. A fan within the housing causes the material to billow, and the slits periodically to open a short distance, allowing light to be transmitted directly onto the screen, thus simulating a flame.
- It has been appreciated by the present inventor, that in the past the primary attention has been directed towards producing relatively high levels of light falling on the screen, and that this has not been particularly conducive to producing a high quality simulated flame.
- Conversely, and in accordance with this invention, there is provided a space heater characterised by the feature that light is directed from the light source through the flame effect means onto a reflector, and reflected light passes again through the flame effect means onto the screen.
- Preferably the flame effect means comprises a sheet of flexible material, and is preferably generally matt, producing only a low level of reflected light. For example, the flame effect means may be provided by a sheet of silky material, such as crepe-de-chine, preferably being of a dark colour, such as dark red, or even black.
- Preferably the flame effect means provides openings, means being provided to cause the flame effect means to move in the housing thereby causing the openings to move.
- Preferably the openings which are provided in the sheet are elongate, and the material is suspended loosely within the housing, being caused to “billow” by the flow of air directed there across, or by mechanical means. Such billowing will cause the slits to open, and for these openings to be seen to travel vertically in the upwards direction, or if desired, downwardly.
- Light passing through the screen will be provided at four levels, as follows:
-
- a) light which passes from the source through the material of the flame effect means to the reflector and from the reflector back through the material of the flame effect means onto the screen;
- bi) light which passes from the source through an opening in the material of the flame effect means to the reflector and through the material onto the screen;
- bii) light which passes through the material onto the reflector and onto the screen via the material of the flame effect means;
- c) light reflected from the flame effect means directly onto the screen;
- d) light passing from the source through one of the openings onto the reflector, and from the reflector back through one or other of the openings onto the screen.
- Conveniently, levels a) and b) may be maintained at a low, ineffective level, whilst the level c) is sufficient only to provide a low level background glow.
- Light at level d) will be intermittent, but at a relatively high level, providing a “smoky” flame effect which may achieve a high level of realism.
- By varying the thickness and colour of the material which provides the flame effect means, and by varying the thickness of the slits, the colour and power of the lamp, and the degree of fogging on the screen, a high quality flame effect means may be produced over a wide range of visual outputs.
- Alternative to the use of the flame effect means being provided by a sheet of flexible material, the flame effect means may comprise a plurality of ribbons.
- There will now be given a detailed description, to be read with reference to the accompanying drawings, of a space heater which is a preferred embodiment of this invention, having been selected for the purposes of illustrating the invention by way of example.
- In the accompanying drawings:
-
FIG. 1 is a vertical sectional view of an electric fire which is the preferred embodiment of this invention; -
FIG. 2 is a schematic perspective view, illustrating principles of performance of the fire; and -
FIG. 3 is an enlarged view illustrating the production of “openings” in the flame effect means. - The space heater which is the preferred embodiment of this invention is an electric fire, comprising a
housing 4 having abase 6 and arear wall 8. Located forwardly of thefront wall 10 anilluminated coal effect 12 may be provided, in conventional manner. Heating means (not shown) is also provided, in conventional manner. - Suspended within the
housing 4 from anupper support 13 is asheet 14 of a lightweight flexible material, such as crepe-de-chine, said sheet being secured loosely by lower securing means 16, adjacent a lower end of the housing. - Mounted adjacent to the lower securing means 16 is a
fan 18 arranged to direct a flow of air upwardly against thematerial 14, to cause the material to billow in an upward direction, and if desired, the lower end of the sheet may be secured to a rear wall of the fan housing. - As is seen from
FIG. 2 , provided in thesheet 14 are a plurality ofslits 20, said slits extending a majority of the height of thesheet 14, and being generally parallel to the side edges of the sheet, there being in the preferred embodiment perhaps sixteen such slits disposed uniformly width-wise of thehousing 4. - Extending upwardly to an
upper closure member 21 is atranslucent screen 24, conveniently of perspex or glass. - Provided within the
housing 10 adjacent a front face of thesheet 14 is alight source 28, arranged to direct light against the front face of thesheet 14, conveniently the light source simultaneously providing an illumination for a solid fuel (wood or coal)effect element 12. - Under the influence of the current of air directly upwardly across the
sheet 14, the slits form openings 21 (seeFIG. 3 ), which move generally in the upwards direction as the sheet billows under the influence of the flow of air. However, alternatively the air flow may be directed downwardly, to cause theopenings 21 to move in the downward direction. Light directed against thesheet 14 in part passes through the material itself, falling against a generallytriangular reflector 32 mounted on therear wall 8 of the housing, light reflected therefrom passing forwardly through thesheet 14 and through thescreen 24. - Some of the light transmitted against the
sheet 14 will also pass through the openings themselves in one direction of traverse of thesheet 14, whilst some light will pass through openings formed by theslits 20 in both directions of traverse of the light. This latter light appears through thescreen 24, and hence to a viewer of the space heater asareas 30 of light moving upwardly of the screen, quickly dissipating due to the lower degree of incidence of light from thesource 28 on the upper parts of thereflector 32, and by virtue of the shape of the reflector itself, simulating flickering flames. - The level of the background glow which will be observed on the
screen 24 will primarily be produced by light being reflected from the front face of thematerial 14 through the screen. The intensity of the background glow will be determined in part of course by the colour of the material of thesheet 14, and may, if desired, be enhanced by a reduction in thickness, so that there is a small contribution to the background glow, by light being reflected from thereflector 32, and passing through thematerial 14 itself. - It has been found that, where the
material 14 is afforded by crepe-de-chine which is black in colour, and thelight source 14 is arranged to transmit a white light, a “smoky” flame effect is produced. Alternatively, a warmer effect may be produced, by the use of crepe-de-chine of a dark red colour, together with an orange light as thelight source 14. - Alternative to the use of the
sheet 14 of crepe-de-chine, the flame effect means may be provided by a plurality of ribbons, suspended between the reflector and the light source in a manner such that light passes from thesource 28 to the ribbons, some light being reflected directly from the ribbons through the screen, other light passing the ribbons and being reflected by thereflector 32, whereby light falling on the screen is at a number of different levels. The ribbons may be of translucent material, such as crepe-de-chine, but may be partly reflective. - In the present specification “comprises” means “includes or consists of” and “comprising” means “including or consisting of”.
- The features disclosed in the foregoing description, or the following claims, or the accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, as appropriate, may, separately, or in any combination of such features, be utilised for realising the invention in diverse forms thereof.
