DESCRIPTION OF THE PRIOR ARTIn the early days, a fireplace can be used for lighting, warming, baking. With the development of economy and technology, the three functions of lighting, warming, baking are gradually improved and separated. These days, a fireplace becomes special warming equipment.
With the development of times, fireplaces are improved from the traditional fireplaces, such as wood burning fireplaces, fuel gas fireplaces or charcoal fireplaces, to electric fireplaces. The electric fireplaces come from the European classical fireplaces to cooperate with acoustics and optics technique to make a great change for the traditional fireplaces. The electric fireplaces are green and friendly-environmental and provide a realistic burning effect.
In these days, electric fireplaces are rapidly developed to substitute the traditional fireplaces. However, the existing electric fireplaces only provide a single color flame and a single function, without aesthetic feeling. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve this problem.

The housing has a window. The projection screen and the plastic screen are located at an inner side of the window. The projection screen is disposed vertically. The plastic screen is levelly disposed at a lower end of a front side of the projection screen. The plastic crystals are disposed on an upper surface of the plastic screen. The first illuminating device comprises a first circuit board and a plurality of first lights disposed on the first circuit board. Each of the first lights comprises at least two different chips. The first illuminating device projects at least one colored light on the plastic screen, and then the light is reflected to the plastic crystals. The flame image plate, the reflection assembly, and the second illuminating device are disposed in back of the projection screen. The flame image plate has a plurality of flame holes thereon. The reflection assembly is rotatable. The second illuminating device comprises a second circuit board and a plurality of second lights disposed on the second circuit board. Each of the second lights comprises at least two different chips. The second illuminating device projects at least one colored light on the reflection assembly, and then the light is reflected to the projection screen.
Compared to the prior art, the present invention has obvious advantages and beneficial effects described as below. Through the plurality of first lights disposed on the first circuit board of the first illuminating device and the at least two different chips of each first light, the first illuminating device can shoot a single color or two colors or a combination of more than two colors of light. The colored light is projected on the plastic screen and then diverted to the plastic crystals. The user can see the plastic crystals illuminating and shining through the window. Through the plurality of second lights disposed on the second circuit board of the second illuminating device and the at least two different chips of each second light, the second illuminating device can shoot a single color or two colors or a combination of more than two colors of light. The colored light is reflected by the reflection assembly to project on the projection screen. The user can see imitation flame dancing behind the projection screen through the window. The present invention can generate single or multi-colored flame to achieve multiple functions. The change effect of the movement and color of the flame can be more perfect and realistic and appreciation. For aesthetic requirements, especially applicable for electric fireplace cabinets and home decoration use, the present invention improves the quality of life and market prospects and has significant economic benefits.
The flame image plate is disposed between the reflection assembly and the second illuminating device and extends outward from the support. The flame image plate is located above the second illuminating device to cover the second illuminating device, so that the light from the second illuminating device is first formed through the flame image plate and then reflected by the reflection assembly to project on the projection screen so as to enhance the flame imitation effect greatly and to reduce the material of the flame image plate and the occupying space effectively. The flame image plate can be installed conveniently.
