Abstract

The invention relates to a flame imitation device for a wall-mounted heater. The flame imitation device comprises a light source, a combustion bed including imitated firewood and embers, and a vertical translucent screen located closely adjacent to the back edge of the combustion bed. The light source is located under the combustion bed. A glittering member is rotatably provided behind the translucent screen. The main body of the glittering member comprises a polyhedron with a polygonal cross section. A reflector is provided on the polyhedron. The glittering member is connected to a rotational driver. Light irradiated from the light source partially transmits upward onto the combustion bed for imitating firewood and embers. Light irradiated from the light source partially transmitted rearward to the glittering member positioned at the back portion of the heater, and reflects the light to the translucent screen. With the rotation of the glittering member, a dynamic flame image presents on the translucent screen. The structure and manufacturing process of the flame imitation device of the invention are simple. Moreover, the reflectors are arranged over the whole polyhedron which resu…
