Description

Transparent flame-like device

The present invention relates to a see-through flame-imitation device, mainly referring to a see-through device with a two-way flame-imitation pattern.

In order to enhance the visual sense of indoor warmth, there are currently devices that can electronically generate flame-like graphics, and can generate flame-like light by lighting to produce a visual sense similar to burning flames. For example, the flame-like electric wall stove of US9739433 has an outer shell, the front of which can provide viewing, and the rear is closed. A light-emitting body, a rotatable flashing element, a flame-like plate, and a projection board are arranged in the outer shell. The flame-like plate has a through hole, so that the light emitted by the light-emitting body can be reflected through the flashing element to the through hole of the flame-like plate to the projection board, and a flame-like graphic appearance can be generated on the projection board.

However, the aforementioned flame-simulating electric wall stove can only display the flame-simulating pattern from the front, but not from the rear, which results in a limited viewing angle.

The electric wall stove of CN210801000 is provided with projection boards on both the front and rear sides of the electric wall stove, and also with flame-imitation boards and light-emitting bodies, and the light-emitting bodies emit light through the through holes of the flame-imitation boards to the two projection boards, so that the flame pattern appearance can be observed from both the front and rear sides of the electric wall stove. Therefore, the electric wall stove can be installed in the center of a wall, and the flame pattern can be observed from both opposite sides of the wall to enhance a better viewing effect.

However, the aforementioned electric wall stove cannot be seen from the front to the rear of the electric wall stove, and the scenery behind the electric wall stove cannot be viewed.

In order to improve the above-mentioned defects, projection panels are arranged on the front and rear sides of the shell of the electric wall stove of CN101608803 to present simulated flame patterns, and a transparent window is extended above the shell, so that when the electric wall stove is installed on the wall, the flame pattern can be viewed from the front and rear, and the scene in front of or behind the wall can be viewed through the upper transparent window.

However, the volume of the aforementioned electric wall stove must be increased in accordance with the transparent window, and the wall must be provided with a correspondingly larger through hole to install the larger electric wall stove, which has the disadvantages of inconvenience in installation and high cost.

The object of the present invention is to provide a flame-simulating device which can display flame-simulating patterns in two directions and can be viewed through.

The present invention includes an outer shell, a control device, a light-emitting device, a flash device, at least one flame-imitation plate, and a projection plate. The outer shell has a chamber in the center, and has hollow areas on the front and rear sides, and a transparent plate is arranged in the hollow area. The light-emitting device has a lamp holder and a plurality of light-emitting bodies. The lamp holder is arranged in the chamber, and the light-emitting bodies are arranged on the lamp holder and are electrically connected to the control device. The flash device is arranged in the chamber and can reflect the light emitted by the light-emitting bodies. The flame-imitation plate is arranged below the chamber and has a plurality of through holes, so that the light reflected by the flash device can pass through the through holes. The projection plate is arranged in the center of the chamber, and has a projection area below, and a perspective area above the projection area. The projection area is mainly translucent; and the perspective area is generally transparent.

In one embodiment of the present invention, the projection area of the projection plate is in a gradient shape, and its transparency increases from bottom to top.

In one embodiment of the present invention, the main body of the projection board can be a transparent material, and a colored film is disposed on the bottom of the projection board by spraying, laminating or coating.

In one embodiment of the present invention, the thickness of the film below the projection area is greater than the thickness of the film above the projection area to form a gradient.

In one embodiment of the present invention, the projection board is composed of a plurality of plates stacked in the height direction, the lower one is a semi-transparent plate corresponding to the projection area, and the upper one is a substantially transparent plate corresponding to the perspective area.

In one embodiment of the present invention, the plate bodies in the projection area may be plural and stacked up and down in the height direction, and each plate body has different transparency, and the transparency of the projection area increases from bottom to top.

In one embodiment of the present invention, the projection plate is composed of a plurality of plate bodies, and at least one semi-transparent plate body is compounded in the thickness direction below the substantially transparent plate body, so as to form the projection area at the bottom and the transparent area at the top.

In one embodiment of the present invention, the flashing device is disposed in the housing, and includes a motor, a shaft, and a plurality of reflective sheets. The motor is electrically connected to the control device, and the shaft is pivoted in the housing and driven to rotate by the motor; and the reflective sheet is disposed on the shaft and can reflect the light emitted by the light-emitting body.

The present invention can be arranged on a wall, and the scene behind the wall can be viewed from the front of the wall through the perspective area above the projection area, which can have the convenience of window viewing.

The present invention can make the light-emitting body of the light-emitting device emit light and the motor of the flashing device operate by the control device, and make the light emitted by the light-emitting body reflect through the reflective sheet and then project toward the through hole of the imitation flame board toward the projection area below the projection board, and produce a flame pattern appearance. In addition, because the transparency of the projection area is a gradient design with increasing transparency from bottom to top, the projection brightness below the projection area is greater than the brightness above, and a realistic visual sense of simulating a larger burning flame below can be produced, and the projection area is semi-transparent, so the flame pattern can be observed from the front or back of the projection board, and the flame pattern appearance effect can be observed from different directions in front of and behind the wall.
