Abstract

A simulated real flame electric fire, for general use in the domestic and office situation, comprises a means of generating the audio and visual effects necessary to create the aura associated with flames and fire by using opaque, or semi-opaque, screens 3 onto which can be projected one or more flame image sequences which have been previously recorded in real situations and thereafter stored on video tape with sound effects and then later regenerated continuously on the fire screen, or screens, by means of a video player 5, colour monitor 6 and lens or mirror optical system 7, 8. The fire may include a plurality of screens (Figure 2) to create a 3-D effect. There may also be included means to release fragrances to impart the olfactory sensation of log burning. <IMAGE>

Description

REAL FLAME EFFECTS IN ELECTRIC FIRES This invention relates to apparatus or component assemblies which are intended, by generating visual and audio effects,to evoke real flame sensations in electric fires and similiar heaters. For many years the marketplace has been supplied with "living flame" heaters where the illulsion of flickering flares was generated by arranging that lightweight aluminium turbine blazes rotate in the hot rais- ing air from one or more red coloured electric lamps and thereby interrupt the coloured light with the radial arms of the rudimentary turbine so that such light falling upon an aluminium reflector evokes the visual sensation of flame flicker.

In addition to this simple system the prior art as taught in G3.1,266,131 illust raes the use of projection methods o of flame simulation using 8.m.m. cine prsject- ions from a continuous loop of coloured film,or the use of cathode ray tubes to directly or indirectly view colour images of flames generated in the phosphor of the tube by means of an undescribed "associated apparatus". Little else is to be found in the prior art so there is a need for an apparatus or component assembly that will oe capable of simulating on a screen,within the electric fire structure, both an audio and visual effect which Will evoke the sensation of a real flame effect fire. According to the present invention there Is provided a nans of generating the audio and visual effects necessary to simulate the air associated ith flames and fire by employing opaque or semi-opaque screens onto which are pro jected one or more flame image sequences which have been previously recorded in real life and thereafter stored on video tape with sound effects and regenerated continuously on the fire screen or screens oy means of a video player, colour monitor and lens or mirror optical system.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings inwhich:- Figure 1 is a side sectional elevation of a three element electric fire with a single opaque screen back-projection video flame image employing a video player and a colour monitor.

Figure 2 is a side sectional elevation of the electric fire of Figure 1 but employing four semi-opaque plastic projection screens in order to achieve an overall space orientated 3-3 effect. eferring to the drawings the real flame effect electric fire conprises a conventional 3-bar element and guard structure 1 with a fibre glass/resin moulded coal or wood simulation cover 2 which is abutted at right angles to an opaque plastic pro jection screen 3. Within the frame or housing 4 of the fire there are fixed component assemblies in the form of a VH3 video player 5,a colour VDU or monitor 6,a focusing lens 7 and a plane mirror 8. Because these units are intended to operate as close to ambient teriperature as possible the fire enclosure is equipped with an air circulation fan 9 which expells air fro the enclosure in the direction of the arrows 10. Inorder to achieve a 3-D effect using the technique of back-project ion it is necessary to employ four or more separate "flame" videos which are combined onto one image using image processing technology as used at present in the professional TV studio and when this is done the image of Figure 3 is obtained which is a composite four plane image. The actual fire system associated with this technique comprises the usual element/guard structure 1 with its fuel simulat- ion cover 2 and frame housing 4 but in this case the video player 5,the colour VDU 6 and the focusing lens 7 are associated with a series of four semi-opaque backprojection screens 11,12,13 and 14 which are separately served by angled positioned plane mirrors 15,16,17 and 18. As before the electric fire enclosure 4 is ventilated by means of the fan 9. In the operation of this invention there are no problems associated with opaque projection screens but it is not so simple to evolve a screen which could be described as semi-opaque. In early e*periments I successfully employed the old principle of Bunsen's Grease Spot Photometer and used sheets of cartridge paper which were rendered translcent by soaking them with a small quantity of non-oxidising oil such as Light Liquid Paraffin of the British Pharmaceutical Coded(1963). In the final versions of the semi-opaque plastic projection screen the required surface was produced in one case by covering it with an array of opaque dots of about lmm diameter which was obtained by silk-screen printing with a thickened solvent solution onto the translucent sheet and in another case by masking the sheet with a lens circular grid and blasting the grid with a fine grade of aluminium oxide abrasive. It will be apparent to those sldlled in the art that this invention has further potential for development and in addition to the already claimed video and audio reproduction of fuel combustion, in the domestic grate, it is possible to even arrange for the real flame electric fire to evolve, from a time controlled aerosol, the tours of pine needles,eucalmtus or wood tars which would add to the video/audio oart the final sensation of the smell of a log fire.
