As can be seen from Figure 1, formed electric fireplace cabinet by upper and lower, left and right and back side frame.What the observer can see from the front only is by left and right sides side frame 4, the simulated hearth that imaging screen 3 is formed and by simulated fuel bed 7, emulation charcoal 5, the emulation fuel fabrication that the simulation ashes are formed.When work, the observer sees is that the dynamic flame image and the integral body that rise slowly on the simulated hearth rear wall are rubescent slightly, the many places bright spot beat just at the fuel assembly of fired state.
As can be seen, dynamic light source device 8 is side in the end from the profile of Fig. 2, and the front is an imaging screen 3, and cabinet is separated into two parts: burner hearth and workspace.Because imaging screen is translucent, so the observer can't see device in the workspace.Between dynamic light source 8 and imaging screen 3, also has a filter 9.Slit on the light transmission light transmission piece 81 of the fixing point light source in the dynamic light source device forms irregular light beam, and the opening that sees through filter 9 projects on the imaging screen 3, forms flame picture.Along with the rotation of light transmission cylinder, these light beams move up, and constantly change projectional angle, make that the flame picture on the imaging screen upwards moves, and constantly change shape, size, brightness in the journey last moving past, and produce the dynamic flame effect.Because the inner surface of light transmission cylinder is the cylindrical surface of sealing,, at this moment produce flame picture clearly so when inner surface treatment becomes the black no-reflection, have only the light beam of some spot light to project on the imaging screen through the printing opacity slit.When the inner surface treatment of light transmission cylinder becomes minute surface, except that seeing through the slit, the direct light of spot light forms the flame picture light beam, and the light of spot light repeatedly reflects on curved surface, focusing, scattering form a composite light beam.Several auxiliary beam of slit generation nothing that this composite light beam sees through on the light transmission cylinder 81 projects on the imaging screen 3, produces the booster flame image.Can make the sense that has levels of observed simulating flame like this.
Can also be processed into the reflecting surface of whole or local yellow, redness, blue look, green etc. at the inner surface of light transmission cylinder 81, make the flame picture that produces different colours and multiple color at imaging screen 3.Make flame picture more rich and varied.
By above-described simple process, produce different dynamic flames, the different flame effect that is produced during with the burning of simulation different fuel to the light transmission cylinder inner surface.
The bulb and the lamp pearl of generation spot light are consumable accessorys, need often to change, and adopt the two-piece type light transmission piece, and U type bayonet arrangement makes the replacing consumable accessory easier and convenient as shown in Figure 6.
As shown in Figure 3, in the dynamic light source device 8, an end of light transmission cylinder 81 links to each other with the axle of motor 802 on being fixed on support 801 by the flexible shaft coupling 806 of rubber, and motor 802 drives light transmission cylinders 81 rotations.The other end frame of light transmission cylinder 81 prevents from that light transmission cylinder 81 from wiping to bump inner light source 805 and bracing frame 804 on flange hollow shaft 808 in rotation process.Flange hollow shaft 808 is fixed on the support 801 by flange, and light source 805 and bracing frame 804 inserts in the light transmission cylinders 81 by hollow shaft 808, simultaneously also with power line 820 by drawing in the light transmission cylinder 81.
As seen from Figure 4, circular hole is opened at the center of the end face 812 of light transmission cylinder 81, and the external diameter circular that Circularhole diameter is slightly larger than the flange hollow shaft has a circular groove, and waxdip wool felt collar 809 its external diameters of thickness 3-5mm equal the external diameter of circular groove.The diameter of bore of pressing plate 810 is identical with the central bore diameter of end face 812, and the several apertures on the limit can be fixed with screw and end face, and the wool felt collar is pressed abd fixed on the end face.Waxdip wool felt collar 809 is put into the groove of end face 812, with several hold-down screws pressing plate 810 and 812 is fixed then, be inserted in flange hollow shaft 808 after the wool felt collar compressed, the flexible bearing of having formed a remarkable especially like this, reduced the coefficient of sliding friction, alleviate motor load, reduced the AC noise of motor, eliminated frictional noise; Prevent the stuck phenomenon that rigging error produces when making motor shaft and flange hollow shaft decentraction and the impact noise of end face and hollow shaft.
Replacements such as the also available ox-hide of the base material of wool felt collar 809, pigskin.
As seen from Figure 5, light transmission cylinder 81 is formed by two, and both sides snap in the cylinder of having formed a base closed behind the U type rib 803.The spot light that inserts in the cylindrical shell sees through the slit formation flame light beam of being opened on the light transmission cylinder, and this light beam moves along with the rotation of light transmission cylinder 81, thereby has formed the dynamic light source that produces the dynamic flame effect on imaging screen 3.
Fig. 7 to Figure 12 is several pattern examples that imaging screen 3 lateral surfaces and side frame face and side frame anterior 4 are formed the simulated hearth wall.Since be to adopt semitransparent pigment or printing ink to generate, and very thin, thus can not influence the brightness and the effect of flame picture, but can increase the sense of reality of classical fireplace furnace, build anti-Piao and return genuine warm atmosphere.
Fig. 7 is traditional hair brick shape figure case.The wall pattern of Fig. 8 for building by rag rubble, Fig. 9 is a sheet Art Stone pattern, and Figure 10 is general similar cement, the wall pattern of lime, and Figure 11 is the pattern that cigarette ash is overworked in prolonged use, and Figure 12 is the round dot type pattern with sense of modernness.
The imaging surface of imaging screen 3 must make the atomizing of smooth glass or frosting, the matsurface that formation one is made up of countless multiple edge bodies on the microcosmic by technologies such as acid etching, sandblast, wire drawings.Like this, the light beam that comes from dynamic light source 8 projection is through these multiple edge bodies refractions and be diffracted into the front surface of imaging screen, makes the observer see flame pattern and can't see inner non-luminous other things.
Imaging screen can also be divided into three zones: imaging district, transition region and flame fade zone.Gradual change connects no obvious line of demarcation between the zone, the flame picture of seeing is more had levels feel and the sense of reality.
Figure 13 adopts silk-screen printing technique to generate this trizonal application example at imaging surface, and Figure 14 adopts simple spraying coating process to generate imaging district, the application example of transition region and flame fade zone.
The structure and the opening shape of the filter 9 on light path between dynamic light source 8 and the imaging screen 3 as seen from Figure 15.Support 91 directly is fixed on the fireplace cabinet.The filter 92 that has indentation is fixed on the support.The enveloping outer enclosure of indentation is circular arc.The light beam that is penetrated by dynamic light source device 8 can only be passed through by opening portion, and all the other then are blocked, so just show the peripheral profile of similar flame on imaging screen 3.Because this filter 9 has a segment distance from imaging screen 3,, make flame effect truer, lively, perfect so the peripheral profile of the flame of being seen on the imaging screen 3 can not produce clear and definite line of demarcation.
