Description
BACKGROUND OF THE INVENTION

The present invention relates to a see-through flame imitation device and, more particularly, to a see-through device enabling observation of simulated flames in two directions while providing a see-through effect.


To increase the indoor visual effect of warmth, a currently available electric type device may generates simulated flames in which lamps generate flame-like light to provide a visual effect similar to burning flames. For an example, U.S. Pat. No. 9,739,433 discloses a flame simulating assembly including a casing having a front end for display and a closed rear end. A light source for producing light, a rotatable flicker element, a flame effect element, and a screen are disposed in the casing. The flame effect element includes at least one aperture, such that the light emitted from the light source can be reflected by the flickering element to pass through the at least one aperture and then projected onto the screen. Thus, images of flickering flames are generated on the screen.


However, the above flame simulating assembly only allows observation of the images of flickering flames from the front side. The images of flickering flames cannot be observed from the rear side, providing limited visual angles.


CN210801000 discloses an electric fireplace including two screens respectively on front and rear sides thereof, a flame imitation plate, and a light source. The light rays emitted from the light source pass through the holes of the flame imitation plate and are projected onto the two screens, such that imitation flames can be seen from both the front and rear sides of the electric fireplace. Therefore, the electric fireplace is suitable for installation in a central portion of a wall, and the simulated flames can be seen from two opposite sides of the wall, thereby increasing the visual effect.


However, an observer at the front end of the electric fireplace cannot see through the electric fireplace, and, thus, cannot see the scene behind the electric fireplace.


To overcome the drawback of the above patent, CN101608803 discloses an electric fireplace including front and rear imaging mechanisms respectively disposed on front and rear sides of a casing to present simulated flames. A see-through window is disposed on a top end of the casing. Thus, when the electric fireplace is installed in a wall, simulated flames can be seen from both the front side and the rear side of the wall, and an observer can see the scene in front of or behind the wall through the see-through window.


However, the volume of the electric fireplace must be increased to match with the see-through window, and the wall must have a larger hole for installation of the electric fireplace having a larger volume, which is inconvenient to installation and expensive.


BRIEF SUMMARY OF THE INVENTION

An objective of the present invention is to provide a see-through flame imitation device enabling observation of simulated flames in two directions while providing a see-through effect.


A see-through flame imitation device according to the present invention comprises a casing, a control device, a light emitting device, a flickering device, a flame imitation board, and at least one projection board. The casing includes a receiving chamber at a central portion thereof and two opening sections respectively on front and rear sides of the casing. Two transparent panels are respectively mounted in the two opening sections. The light emitting device includes a lamp base and a plurality of light emitting members. The lamp base is disposed in the receiving chamber. The plurality of light emitting members is disposed on the lamp base and electrically connected to the control device. The flickering device is disposed in the receiving chamber and is configured to reflect light rays emitted from the plurality of light emitting members. The flame imitation board is disposed below the receiving chamber and includes a plurality of through-holes through which the light rays reflected by the flickering device are passable. The at least one projection board is disposed in a central area of the receiving chamber and includes a projection section at a lower portion thereof and a see-through section above the projection section. The projection section is substantially translucent. The see-through section is approximately transparent.


In an example, the projection section of the at least one projection board is gradient and has increasing transparency from bottom to top.


In an example, the at least one projection board has a main body made of a transparent material. A film having a color is formed on the lower portion of the at least one projection board by spraying, bonding, or coating.


In an example, a thickness of the film at a lower end of the projection section is greater than a thickness of the film at an upper end of the projection section, forming a gradient thickness.


In an example, the at least one projection board includes a lower board and an upper board stacked on top of the lower board in a height direction. The lower board is translucent and corresponds to the projection section. The upper board is substantially transparent and corresponds to the see-through section.


In an example, another lower board stacked on the lower board in a thickness direction perpendicular to the height direction. The lower board and the another lower board have different transparencies, such that the projection section has increasing transparency from bottom to top.


In an example, the at least one projection board includes at least one first board which is substantially transparent and at least one second board which is translucent and which is stacked on a lower portion of the at least one first board in a thickness direction, thereby forming the projection section and the see-through section above the projection section.


In an example, a reflective board is disposed in the receiving chamber of the casing. A portion of the light rays emitted by the plurality of light emitting members passes through a portion of the plurality of through-holes of the flame imitation board and is projected onto a side of the at least one projection board. Another portion of the light rays emitted by the plurality of light emitting members passes through another portion of the plurality of through-holes of the flame imitation board and is reflected by the reflective board to project onto another side of the at least one projection board.


In an example, a plurality of light concentrating shields is disposed on the lamp base and defines a space and an opening. The plurality of light emitting members is disposed in the space defined by the plurality of light concentrating shields and is configured to emit the light rays toward the opening.


In an example, the flickering device includes a motor, a shaft, and a plurality of reflective plates. The motor is electrically connected to the control device. The shaft is rotatably received in the receiving chamber and is configured to be driven by the motor to rotate. The plurality of reflective plates is disposed on the shaft and is configured to reflect the light rays emitted by the plurality of light emitting members.


The see-through flame imitation device according to the present invention can be mounted in a wall. An observer at the front side of the wall can see the scene behind the wall via the see-through section above the projection section, and an observer at the rear side of the wall can see the scene in front of the wall via the see-through section above the projection section, thereby providing convenience as a window.


In operation of the see-through flame imitation device according to the present invention, the control device is operated to activate the plurality of light emitting members of the light emitting device to emit light and to active the motor of the flickering device to operate. The light rays emitted by the plurality of light emitting members are concentrated by the plurality of light concentrating shields to be incident toward the plurality of reflective plates which reflects the light rays to pass through the plurality of through-holes of the flame imitation board and then project onto the projection section at the lower portion of the projection board, thereby generating simulated flames. Furthermore, since the transparency of the projection section is a gradient design (the transparency increases from bottom to top), the projection brightness at the lower end of the projection section is higher than that at the upper end of the projection area. This enables generation of a simulated flame pattern whose lower portion has bigger flames, thereby providing a lively visual effect. Furthermore, since the projection section is translucent, the simulated flames can be observed from the front side or the rear side of the projection section. The see-through flame imitation device according to the present invention enables observation of the simulated flames from both the front side and the rear side of the wall.


The present invention will become clearer in light of the following detailed description of illustrative embodiments of this invention described in connection with the drawings.

The projection board 6 is a planar board and is disposed vertically in a central area of the receiving chamber 12. The perimeter of the projection board 16 is clamped in the insertion groove 15. The projection board 6 includes a projection section 61 at a lower portion thereof and a see-through section 62 above the projection section 61. The projection section 61 is substantially translucent and may be gradient, such that the transparency of the projection section 61 increases from bottom to top. The see-through section 62 may be approximately transparent.


The projection board 6 has a main body made of a transparent material, such as transparent glass, transparent plastic, or any other transparent board.
