Description

Electric fireplace flame curtain with adjustable carbon bed

This invention relates to an electric fireplace, and more particularly to an electric fireplace flame curtain with an adjustable carbon bed. Background technique

In prior art simulated fireplace constructions, the simulation of the fireplace combustion body is typically divided into two parts, a portion of which simulates the combustion of the fireplace, which is typically accomplished by projecting varying light onto an imaging screen having an imaging function, such as disclosure. 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-transmissive aperture is disclosed in the patent document published on September 5, 2007, with the publication number of CN 200944291. The light-shielding body, 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, and the light-shielding body cooperates with a transmission mechanism. 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 other part is the simulation of charcoal in the burning state of the fireplace. This part is usually fixed with a structure similar to wood or carbon block. It is placed under the imaging screen to simulate charcoal fire. For example, the public date is April 7, 2004. For the patent document CN 2610233, a simulated wood for a fireplace heater is disclosed, which is composed of a simulated wood substrate and a light source. The base body is an irregular transparent cavity of the shape simulation wood, and a light-emitting diode or a lamp bead is arranged in the cavity. , each LED or lamp bead connected or After that, the substrate is connected to the external power source through the wire. The simulated wood substrate adopts a translucent material body, and the outer surface is irregularly spaced with a pigment layer. The pigment layer can select various colors according to the simulation needs, and usually adopts a dark brown color similar to wood. The patent combines the base of the simulated wood with the light source. The light source is arranged in the simulated wood matrix. The base body is made of transparent body, and its appearance is irregularly coated with pigment. Therefore, when the internal light source emits light, it can produce a simulation of wood burning when the light and dark are staggered. The combustion effect is simple in structure, the combustion effect is realistic, and the shape and fidelity are closer to natural effects. The charcoal fire simulated by wood or carbon bed similar to this fixed structure, the color change of the charcoal fire is mainly realized by the pigment layer coated on the outer surface of the outer surface of the wood or carbon bed. Therefore, the shape of the charcoal fire on each electric fireplace The degree of light and darkness is fixed and will not change. In this way, it will cause the external appearance of the charcoal fire to be dull, affecting the ornamental effect and interest of the charcoal fire. In addition, since the brightness of the charcoal fire on the electric fireplace has not changed during the use of the electric fireplace, the lack of real-time charcoal fire has the illuminating characteristics of the dark and bright sparks, and lacks the sense of reality, which also seriously affects the simulation effect of the charcoal fire. . Disclosure of invention

The invention provides an electric fireplace flame with an adjustable carbon bed which can be freely changed and has a good ornamental effect in order to solve the problems of fixed shape, unobtrusive appearance and poor viewing effect of the prior art electric fireplace. screen.

Another object of the present invention is to solve the problem of the fixed brightness of the charcoal fire, the lack of realism, and the poor simulation effect of the charcoal fire in the prior art electric fireplace, and provide a charcoal fire burning around the charcoal burning point or between the charcoal fires. The flames are changing and stagnation, like a flame burning around a charcoal fire or burning among various charcoal fires, and the carbon block has a bright Martian spot of light and darkness, and the sense of reality is strong. An electric fireplace flame curtain with an adjustable carbon bed.

The specific technical solution adopted by the present invention for achieving the above technical purpose is: an electric fireplace flame curtain with an adjustable carbon bed, the flame curtain has a container-like structure, and the front wall and the rear wall of the container are both transparent. Structure, the front wall of the container is provided with an image forming mechanism, and the container is provided with a plurality of movable hysteresis blocks with a plurality of transparent surfaces. The flame curtain is designed as a container-like structure, an image forming mechanism is disposed on the front wall of the container, and a plurality of light-blocking structure of the light-blocking carbon block is disposed in the container to replace the wood or carbon bed of the integrated structure in the conventional electric wall furnace. In this way, due to the relative positioning of the containers, the blocks of different sizes and shapes of the hysteresis block can be randomly stacked within the scope of the container to form a carbon bed structure of various shapes, and the user can customize the visual preferences according to the individual. A personalized carbon bed structure is provided to meet the viewing requirements of different users for electric fireplaces, and to enhance the viewing effect of electric fireplaces. The light-transmissive surface on the hysteresis block refers to one side of the block of hysteresis. It can transmit light and refract and reflect the transmitted light. It can also reflect external light, thus causing the light to lag. There are numerous times of refraction between the interior of the carbon block and the block of hysteresis, between the block of hysteresis and the imaging screen, and finally the hysteresis effect is achieved. In addition, the shape and size of the hysteresis block, the number of light-transmissive surfaces, and the light transmittance thereof can be selected according to personal preference, and the opaque surface can also be provided with a opaque surface. It can also be freely increased or decreased according to personal preference, but generally does not exceed half the height of the front wall of the container, leaving enough flame gap and carbon bed to adjust the space for the container. The front and rear walls of the light transmissive structure ensure that the imaged light of the electric fireplace passes through the container, creating a flame image on the imaging screen.

Preferably, the container is a vertically arranged flat box structure, and the image forming mechanism is a sheet-like image forming screen disposed on the front wall of the container or a matte structure or an image film disposed on the front wall of the container, the image forming screen and the matte surface The structure or imaging film is disposed on one side of the front wall of the container and has the same size as the front wall of the container. Design the container into a vertically arranged flat box structure, the width and height of the container and the electric fireplace The size of the imaging screen is adapted so that the front wall of the container can be directly used as an image forming mechanism of the electric fireplace to simplify the structure of the electric fireplace; and the thickness of the container in the front and rear direction of the electric fireplace is relatively small, and can be adapted to the width and height of the electric fireplace. The large, low-thickness structure requires sufficient light to pass through the container, giving the imaging screen at the front of the container sufficient brightness. The image forming mechanism may be a sheet-like image forming screen disposed close to the front wall of the container, and may be a matte structure directly disposed on the front wall of the container, or may be an image film coated or pasted on the front wall of the container, which belongs to the existing The imaging screen, the matte structure and the imaging film are preferably disposed on the inside of the front wall of the container, or on the outside of the front wall of the container, for the front wall of the thinner container or directly on the front wall of the container with a thinner imaging screen. In this case, the matte structure or the image film structure may also be disposed on both the inner and outer sides of the front wall of the container.

Preferably, the hysteresis block is a polyhedron having a plurality of refractive surfaces on its surface, and the polyhedron is integrally formed of a homogenous transparent body, and the portion adjacent to the front wall of the container or the image forming screen constitutes a charcoal bright region, and the periphery thereof has a wedge-shaped gap. Forming a light-stagning zone. The refractive surface can be a flat surface or a curved surface or other curved surface. A polyhedral retarded carbon block having a plurality of refractive surfaces has a refractive and reflecting function, which is irradiated by irregularly varying light emitted by an electric fireplace flame generating device, due to the refraction of the hysteresis block, sometimes and certain The angle of light will be focused on the imaging screen. From the imaging screen, the surface of the hysteresis block that is in close contact with the front wall of the container or the image screen will form a charcoal bright area, which is very similar to the burning area of charcoal burning or star-shaped. The Mars light spot is sometimes absent due to the light of the flame generating device. Therefore, the burning zone or the Martian light spot is bright and dark, which is very similar to the burning light of the real charcoal fire, and has a strong sense of reality. In addition, some of the changed light is deflected multiple times through the block of hysteresis, and some of the changed light is directed onto the imaging screen, and some of the light is reflected by the surface of the hysteresis block, that is, Multiple reflections in the wedge-shaped gap, the superposition of many light rays, plus the human visual residue and the synthesis of the visual image of the brain, and finally around the charcoal fire area The stagnation zone is formed in the wedge-shaped gap, and the stagnation zone gives the feeling that the flame stays in the vicinity of the carbon block gap and continuously tumbling and burning, which enhances the authenticity of the carbon bed and greatly enhances the aesthetic beauty of the electric fireplace. . The hysteresis block can also adopt a translucent structure. Due to the poor light transmission effect of the translucent structure, the light transmittance of the carbon bed is lowered, and the brightness of the Mars spot and the stagnation zone is weak, but the simulated carbon bed carbon fire has A sense of guilt, there is another mood.

Preferably, the container is further provided with a simulated carbon block having a natural charcoal shape, and the simulated carbon block is a transparent or translucent structure, and is integrally formed of a homogenous material. Mixing a suitable amount of transparent or translucent structure of carbon blocks in the hysteresis block can make the carbon bed structure closer to the real charcoal fire. The charcoal shape here can be a block structure or a strip or a bifurcated strip. Structure. For the simulated carbon block of transparent or translucent structure, it is preferable to use the semi-transparent structure of the simulated carbon block. Since the semi-transparent structure of the simulated carbon block has less light transmission, the brightness of the simulated screen is darker, so that it is in the carbon A portion of the carbon block with a lower degree of combustion is present in the bed, and at the same time, the simulated carbon blocks of the translucent structure are illuminated by the light emitted by the electric fireplace flame generating device and the reflected light of the polyhedral block of the polyhedral structure. The brightness of the carbon block is significantly greater than the brightness of the central portion of the carbon block. This structure is consistent with the structural characteristics of the carbon block at the beginning of combustion, and therefore, the simulation effect of the charcoal fire can be significantly improved. The ratio of hysteresis block to simulated carbon block is generally 2 to 1 to 8 to 1.

Preferably, the front wall and the rear wall of the container have a flat or curved structure, and the width of the rear wall of the container is adapted to the front wall of the container, and the height of the rear wall of the container is the same as or smaller than the front wall of the container, and the bottom plate of the container is Transparent or translucent structure. Since the front wall of the container doubles as the image forming screen for the electric fireplace, the front wall of the container of the flat or curved structure conforms to the structural requirements of the general electric fireplace for the image forming screen. The rear wall structure of the container preferably adopts the same structure as the front wall of the container, so that the entire container is formed into an equal thickness structure, and regional variation of the brightness of the image forming screen due to the inconsistency of the container thickness can be avoided. If design time Considering the use of this change, it is conceivable to adopt a container structure which is thinner in the middle and thicker on both sides, in order to conform to the structural characteristics that the general combustion material has high brightness at the combustion center and the edge brightness is lowered. In addition, the height of the rear wall of the container is preferably the same as the height of the front wall of the container, although the height of the hysteresis block placed in the container is generally not close to the top of the front wall of the container, but if the material is saved, the height of the rear wall of the container is lowered. In the solution, the edge line of the upper end of the rear wall of the container may appear on the imaging screen under the illumination of the light generated by the flame generating device, which may affect the authenticity of the flame simulation of the electric fireplace and affect the viewing effect. The use of irregular edge lines on the upper end of the rear wall of the container can compensate for this defect to some extent. Since the container has a certain thickness, when the user looks down from above, the charcoal fire at the bottom of the container should be a bright structure. Therefore, the bottom plate of the container is transparent or translucent, and is illuminated by the imaging light source at the bottom of the electric fireplace. The carbon block at the bottom of the vessel can exhibit a bright structure to conform to the structural characteristics of the charcoal fire.

The flame curtain is disposed on a front side of the electric fireplace flame generating device, wherein the flame generating device is a rotating shaft driven by the motor and a reflective strip disposed on the rotating shaft, and may also include a mandrel, a rotating drum and a rotating drum. A bushing type flame generating device for reflective strips. The flame curtain of the present invention is disposed on the front side of the electric fireplace flame generating device, the front wall of the container on the flame curtain is in the position of the conventional electric fireplace imaging screen, and the bottom of the container is equivalent to the position of the traditional electric fireplace carbon bed, two preferred The flame generating devices of the structure are all prior art, and other flame generating devices of the prior art can also be used.

As a variant of the invention, the bottom wall of the front wall of the container has an L-shaped outer shape, and the inner side of the convex portion forms a groove, and the groove has a trapezoidal or rectangular cross section. This scheme strengthens the bottom structure of the charcoal fire, and makes the structure of the charcoal fire three-dimensional, thereby greatly enhancing the three-dimensional sense of the charcoal fire. A groove having a trapezoidal or rectangular cross section connects the upper and lower charcoal fires in the carbon bed Naturally, closer to the natural form of charcoal fire.

If the grooves in the above variation are separately provided, the following structure is formed: a container chamber is provided on the front side of the bottom of the container, a light-blocking carbon block is arranged in the container chamber, and a cover plate and a cover plate are arranged on the container chamber. An imaging device is disposed on the inner side, and the container cavity has a trapezoidal or rectangular structure in cross section. The structure of the container and the container is a split structure, and the effect is substantially the same as the above variation. In addition to the stagnation block, a simulated carbon block with a natural charcoal shape can also be provided in the cavity.

In the above two variants, the bottom plate of the container and the container chamber is also of a transparent or translucent structure. The bottom plate of the transparent or translucent structure, under the illumination of the imaging light source at the bottom of the electric fireplace, the carbon block at the bottom of the container can exhibit a bright structure, in accordance with the structural characteristics of the charcoal fire.

In the above two variants, preferably, a flame generating device is disposed below the container or the container cavity, and the flame generating device is a rotating shaft driven by the motor and a reflective strip disposed on the rotating shaft, and may also be used. A sleeve type flame generating device comprising a mandrel, a rotating drum and a reflective strip disposed on the rotating drum. Since the groove or the container cavity at the bottom of the container is disposed substantially in a lateral direction, the light on the rear side of the container is difficult to form an effective simulated image on the bottom imaging screen in an inclined or even horizontal state, and therefore, in the container or the container A flame generating device for the imaging screen at the bottom of the container is specially arranged under the cavity, so that the imaging light can simulate the bright spot of the fire when the charcoal fire is on the front wall of the bottom of the container or the imaging mechanism on the container cavity, thereby enhancing the realism of the charcoal fire.

The essential effect of the invention is that it effectively solves the problem that the charcoal fire has a fixed shape, a dull appearance and a poor viewing effect in the prior art electric fireplace, and at the same time, solves the carbon fire brightness existing in the electric fireplace of the prior art. Fixed, lack of realism, poor charcoal fire simulation effect, the carbon fire structure of the present invention can be arbitrarily changed, with a bright and dark Martian spot and a sense of light retention, a good viewing effect and a strong sense of reality. , DRAWINGS

In the case of an electric fireplace flame curtain with an adjustable carbon bed, the flame curtain is placed on the front side of the electric fireplace flame generating device, and the light source of the electric fireplace is reflected by the flame generating device onto the flame curtain, and the position of the carbon block is not disposed on the upper portion of the flame curtain. The presented image is substantially identical to the prior art, forming a burning flame image upon exposure of the beating imaging light. When the light hits the hysteresis block in the lower part of the flame curtain, due to the refraction of the hysteresis block, some time and some angles of light will be focused on the imaging screen. From the imaging screen, the surface of the hysteresis block and the front wall of the container or the image screen will form a charcoal bright area, which is very similar to the burning area of charcoal burning or the star point of Mars, due to the light of the flame generating device. There is no time at the moment. Therefore, the burning zone or the Martian spot is bright and dark, which is very similar to the burning of the real charcoal fire, and the realism is very strong. In addition, some of the changed light is deflected multiple times through the block of hysteresis, and some of the changed light is directed onto the imaging screen, and some of the light is reflected by the surface of the hysteresis block, that is, Multiple reflections in the wedge-shaped voids, the superposition of many light rays, plus the human visual residue and the synthesis of the visual image of the brain. Finally, a stagnation zone is formed in the wedge-shaped gap around the charcoal fire bright area, and the light-storing zone is given. The feeling that the flame stays in the vicinity of the carbon block gap and continually tumbling and changing combustion enhances the authenticity of the carbon bed and greatly enhances the aesthetic appeal of the electric fireplace (see Figure 7). For the structure with semi-transparent simulated carbon block in the container, since the semi-transparent simulated carbon block has less light transmission, the brightness is darker on the image forming screen, so that a part of the charcoal fire structure has a lower degree of combustion. Block, the semi-transparent structure of the simulated carbon block under the illumination of the electric fireplace imaging light and the baffle of the hysteresis carbon block, the brightness at the contour of the block is significantly greater than the brightness of the central portion of the carbon block, the structure conforms to the carbon block or The structural characteristics of firewood just beginning to burn, therefore, can significantly improve the simulation effect of charcoal fire.

For the structure with a groove or a cavity in the bottom of the flame curtain, the illumination light of the groove or the cavity mainly depends on the flame generating device below it, and the flame effect is basically the same as that of the main scheme, but this scheme strengthens the charcoal fire. The bottom structure makes the structure of the charcoal fire three-dimensional, which greatly enhances the three-dimensional sense of the charcoal fire. The upper and lower charcoal fires in the carbon bed are naturally connected, which is closer to the natural form of the charcoal fire.

When it is necessary to change the shape of the carbon bed, simply open the electric fireplace cover, stir or increase or decrease the carbon block in the flame curtain container, and also change the proportion of the carbon blocks of different structures to form different shapes and structures of the carbon bed, so that The change in the shape of the carbon block, not only the shape of the carbon bed is changed, but also in the carbon bed The ray-reflecting lines, bright areas and stagnation areas of the light are also all changed. Therefore, the user presents a completely different new scene with completely different visual effects.
