Description

Reflective electric fireplace

The present invention relates to a simulated fireplace, and more particularly to a reflective electric fireplace. Background technique

In the prior art electric fireplaces, the flame simulating devices mostly adopt the following two types: one is to rotate the horizontally mounted rotating shaft blades parallel to the imaging screen, and the reflecting surface on the blades reflects the light from the imaging light source, thereby generating radial The moving light, which is projected onto the imaging screen, produces a flame moving from bottom to top on the imaging screen to complete the simulation of the flame; the other is mounted horizontally by rotating parallel to the imaging screen. The hollow cylindrical light-transmissive tube, that is, the axis of the light-transmitting tube is parallel to the horizontal plane, and the light-transmitting light is transmitted through the fixed light-transmitting hole on the light-transmitting tube, and the shape of the flame is formed by the flame hole on the flame plate, and then Projected onto the imaging screen and mirror glass for flame vision. Although these two methods can produce the soaring effect of flame combustion, since the reflected or transmitted light has only radial motion, the simulated flame is only the vision that is moved from the bottom to the left through the visual residual in the human brain. Pattern, the flame pattern simulated in this way is scattered on the entire imaging screen, and has a single shape, lacking the structural features of the real flame, that is, the lack of a clear shape of the real flame, and the outline of the flame is unclear. A flame simulation device for an electric fireplace, including a light source, a flame plate, a translucent imaging screen, a translucent glass screen, and a light transmission, is disclosed in the patent document published on September 5, 2007, the disclosure of which is incorporated herein by reference. The light-shielding body of the hole, the simulated fuel bed in front of the cavity of the casing, the light-shielding body with the light-transmitting hole is placed behind the flame plate, the glass screen is fixed in front of the image forming screen, the light source is matched with the light-shielding body, the light-shielding body and a transmission mechanism Cooperate. With such a structure, the light shielding body can be installed not only horizontally, but also vertically and with the transmission mechanism to form axial and radial moving light, and the light forms a flame shape through the flame hole on the flame plate, and then projects onto the imaging screen and On the glass screen, it produces a vertical rise of the flame and a horizontally floating visual effect. The patent adopts a technical scheme for letting the imaging light pass through the flame hole on the flame plate and using the structural features of the flame hole to define the shape characteristic of the flame pattern on the imaging screen, and to some extent clarifies the outer shape of the simulated flame, but due to the flame The flame holes on the plate are fixed and have very clear boundaries, so the simulated flame structure is dull and lacks realism. In addition, the prior art electric fireplace has an appreciation effect only when it is used. When the electric fireplace is stopped, the viewing window of the electric fireplace is usually a single plane, and the time for the user not to use the electric fireplace is also large. For example, in the hot summer season, a plane with no decorative effect will appear in the room, which will seriously affect the decoration effect of the room. In addition, the imaging screen of the existing electric fireplace is basically a flat or curved structure, so the flame simulated by the electric fireplace is actually a flat pattern, which lacks a stereoscopic effect. Disclosure of invention

The invention solves the problem that the flame pattern existing in the existing electric fireplace has a single shape, lacks the structural features of the real flame and the flame structure, and lacks the realism problem, and provides a reflective electric power with a clear flame shape and a strong realistic feeling. fireplace.

Another object of the present invention is to solve the problem that the existing three-dimensional effect of the flame of the electric fireplace is poor, the art decoration is lacking when the use is stopped, and the decoration effect of the room is seriously affected, thereby providing a strong three-dimensional flame and when the electric fireplace is stopped. You can also enjoy the reflective electric fireplace that can beautify the environment. The specific technical solution adopted by the present invention to achieve the above technical object is: a reflective electric fireplace comprising a casing, an imaging light source, a light processing device and an imaging screen, wherein the light processing device is disposed under the electric fireplace imaging screen. One side of the front wall, a side of the rear wall of the electric fireplace is provided with a non-planar reflector, the imaging light source is disposed below the reflector and lower than the light processing device, and the light source is disposed above the imaging light source and the light processing device The path of the electric fireplace to image the light is: an imaging light source, a light processing device, a reflective body, and an imaging screen. The imaging light source of the prior art electric fireplace is usually disposed on the front wall side of the electric fireplace, and the light processing device is disposed on the side of the rear wall of the electric fireplace, and the light emitted by the imaging light source is reflected by the light processing device to the front wall of the electric fireplace. The image is screened to form a simulated flame pattern. The invention provides an imaging light source on the side of the rear wall of the electric fireplace, and a light processing device on the side of the front wall of the electric fireplace, and a non-planar reflector on the side of the rear wall of the electric fireplace, the light emitted by the imaging source The light processing device first reflects on the non-planar reflector, and then reflects the light onto the imaging screen on the front wall of the electric fireplace through the non-planar reflector, so that the image light reflected by the light processing device can pass through the non-planar reflector. It is controlled to concentrate on certain areas to simulate a clear, realistic flame pattern on the imaging screen. The non-planar structure referred to herein refers to a surface structure including a plurality of directions of reflection for parallel rays, which can change the direction of the imaged light reflected by the light processing device, thereby causing the light to be irradiated according to a certain rule. A certain area, the present invention utilizes this structure to provide a relatively clear structural feature to the flame on the imaging screen, although such a non-planar structure is a major feature of the reflector, but is external to or between such structures. Connecting the transition area also allows for a local planar structure. The specific form of the non-planar structure can be simulated according to the mutual positional relationship between the imaging light source, the light processing device, the reflector and the imaging screen, and combined with the desired flame shape structure, and then corrected according to the actual visual effect to achieve the best. Mode Proposed effect. The image light source and the light processing device are arranged with a light blocking body, which is a direct light blocking imaging screen or a reflector for blocking the imaging light source, thereby ensuring the dynamic processing of the light of the imaging light source through the light processing device, preventing a fixed flame from being formed on the imaging screen. , to ensure the dynamic simulation of the flame.

Preferably, the reflector is a flame-shaped panel having a concave structure, and the side of the flame-patterned panel having a concave structure faces the image-forming panel. The light reflected by the concave structure may tend to concentrate, thereby forming a local concentrated combustion zone on the image forming screen, so that the outer shape of the flame is clear.

Preferably, the flame-patterning plate is a reflector or at least on a side facing the image-forming panel, the reflector is a reflective sheet or a reflective sheet, and the reflective layer is a reflective coating or a reflective film. Reflector refers to a plate-like object that has its own reflective ability, usually a thin metal plate or sheet for easy molding; a prefabricated flame-shaped plate can also be used, and a reflective coating or reflective is provided on the side of the flame-shaped plate facing the image-forming panel. The film is used to reflect light, and the prefabricated flame-patterned panels are usually made of non-metallic structures such as plastics, resins, and the like.

Preferably, the concave structure on the flame stencil includes spherical or ellipsoidal surfaces of different sizes. The light reflected by the concave spherical or ellipsoidal structure can form a burning flame pattern on the imaging screen.

Preferably, the concave structure on the flame patterning plate comprises strip-shaped grooves of different sizes, the strip-shaped grooves having an arc-shaped cross section, and the longitudinal direction of the strip-shaped grooves is close to the height direction of the electric fireplace. The strip groove can form a strip-shaped flame pattern on the image forming screen. Considering that the flame has an upward burning characteristic, the length direction of the strip-shaped groove is usually set to be close to the height direction of the electric fireplace to form an upward burning of the strip. Flame pattern.

Preferably, the flame molding plate is disposed obliquely, and the upper end of the flame molding plate is spaced from the imaging screen by a distance greater than the lower end of the flame molding plate. The upper end of the flame molding plate is inclined toward the rear wall, which is advantageous for Reflecting the imaged light to a higher position to ensure a higher burning height of the flame on the imaging screen. In addition, some concave structures at the lower end of the flame patterning plate can reflect the imaged light to a higher position on the flameboard. , thus achieving multiple reflections, bringing the flame to a higher level.

Preferably, the light blocking body located above the imaging light source is a rear light blocking plate fixed to the rear wall of the electric fireplace; the light blocking body located above the light processing device is a front light blocking plate or a simulated carbon bed capable of meeting the light blocking requirement, the front block A light panel or simulated carbon bed is attached to the front wall of the electric fireplace at a higher position than the rear light barrier. The rear light barrier blocks the imaging light source from directing the imaging screen or reflector, while the front light barrier is a direct light imaging screen that blocks the imaging source. The width of the front and rear light barriers has a certain correspondence with the upper and lower positions. The principle is to ensure that the light of the imaging source is reflected by the light processing device to the reflector, and the light of the imaging source is prevented from being directly directed to the imaging screen or the reflector. When the simulated carbon bed is placed under the imaging screen of the electric fireplace, if the position of the simulated carbon bed can play the same light blocking function as the front light barrier, the simulated carbon bed can be used as the front light barrier, and there is no need to set the front gear. The light plate, of course, can also be used to set the simulated carbon bed on the front light barrier. This structure has no special requirements for the simulated carbon bed, and can be randomly selected according to the simulation effect.

As an improved form of the reflective electric fireplace, the imaging screen is a three-dimensional relief painting of a light transmitting structure and a developing mechanism disposed on the back of the three-dimensional relief painting, and the developing mechanism is a matte structure disposed on the back of the three-dimensional relief painting. , imaging film or imaging sheet. Although the flame profile simulation process of the present invention does not have any particular requirements for the imaging screen of an electric fireplace, various prior art image frame structures can be used in the present invention, such as a light transmissive plate with a frosted structure or an image film, with a matte finish. The light transmissive sheet of the structure or the like, but if the image forming screen adopts a three-dimensional relief drawing of a light transmitting structure and a developing mechanism disposed on the back side of the three-dimensional relief drawing, the performance of the electric fireplace can be substantially improved. Here, the three-dimensional relief painting of the light-transmitting structure replaces the screen structure of the ordinary imaging screen, and is disposed on the back of the three-dimensional relief painting. The developing mechanism is equivalent to a matte structure or an imaging film on a general imaging screen. After the imaging screen adopts the three-dimensional relief painting of the light-transmitting structure and the developing mechanism disposed on the back of the three-dimensional relief painting, the appearance of the imaging screen and the flame simulation effect have undergone great changes. In appearance, the traditional imaging screen is usually only a single plane, which has no decorative effect. When the electric fireplace is stopped, it lacks art decoration, which affects the overall decorative effect of the room. The three-dimensional relief painting is used as the screen of the imaging screen. The three-dimensional structure of the relief painting itself is an artistic picture, which also has an ornamental effect when the electric fireplace stops working, so that the room environment can be beautified. From the flame simulation effect, the imaging screen of the existing electric fireplace is basically a flat or curved structure, so the flame simulated by the electric fireplace is actually a flat pattern, so the stereoscopic effect is lacking, and the self-structure of the three-dimensional structure of the relief painting The characteristics determine its obvious effect on the simulated flame to enhance the stereo effect, which can significantly improve the flame simulation effect of the electric fireplace and enhance the stereoscopic effect.

Preferably, the light processing device is a motor-driven rotating shaft and a reflective strip disposed on the rotating shaft or a sleeve-type light processing device including a mandrel, a rotating drum, and a reflective strip disposed on the rotating drum. The light processing devices of the two preferred structures all have the characteristics of good flame simulation effect, simple setup, and low cost, and other light processing devices of the prior art can also be used.

The essential effects of the invention are: It effectively solves the single shape of the flame pattern existing in the existing electric fireplace, the structural features lacking the real flame, the poor stereoscopic effect of the flame, the lack of artistic decoration when the electric fireplace is stopped, and the serious influence on the room. The problem of decorative effects. The invention has the advantages of simple structure, clear flame shape and strong stereoscopic effect, and can enjoy the relief picture and the dual use of the electric fireplace when the electric fireplace is stopped, and beautifies the room environment, which is a significant improvement on the traditional electric fireplace, and has a remarkable economy. benefit.
