Electric fireplace
Fireplaces are common household devices that are used to provide heat and a pleasing aesthetic. Fireplaces are an efficient method for providing warmth and creating the appeal of a fire within a room. Heating is necessary for the human being from ancient time. People warm themselves by burning branches of trees since the invention of how to make fire. With the increasing of living standard, electric fireplace has been one of the popular heating means. Fireplaces have been a part of permanent dwellings since such dwellings were first built. In the early years before central heating was developed, fireplaces were an important source of the heat that warmed these dwellings and their occupants. However, after central heating became available, the greater convenience and efficiency of central heating relegated fireplaces to an esthetic function for the most part. A fireplace is typically mounted in a wall of a structure and includes one or more air passages running into and out of the fireplace. The plurality of passages creates an air plenum system. A portion of the air plenum system typically includes one or more air intakes coupled to passages used to take room air, or air from the room in which the fireplace is disposed, and direct the room air through passages running adjacent to the combustion chamber. The room air is heated as it passes adjacent to the combustion chamber and is eventually exhausted through an air exhaust back into the room. However, traditional fireplaces are expensive, create smoke, and are a fire hazard so artificial fireplaces or stoves are popular alternatives. Artificial fireplaces are less expensive than traditional fireplaces and they do not use actual flames, so there is no smoke or fire hazard. Electric fireplaces of various designs have been used for many years. Electric fireplaces are ordinarily installed in locations where the appearance of a combustible fuel-burning fireplace is desired. Electric fireplaces may also be installed in locations where traditional combustible fuel-burning fireplaces would not fit. For example, electric fireplaces are typically not as deep as traditional fireplaces, thereby permitting installation in a greater number of applications. The means of electric heating in existence have two categories: the heater only supplying warm and the electric fireplace having both flame vision and warming function. The latter is an electric fireplace unit having a fire simulating assembly to simulate flame vision. From standard wood burning fireplaces to electric and gas fireplaces that simulate to visual effects of a real fireplace without all of the complications. Illuminating systems have also been used to make fireplaces more attractive. Electrical lighting circuits have been available to display a flickering effect. The fire simulating assembly is generally divided into two categories. The first kind of the assembly is a simulating combustion medium such as coal or burning branches. Such combustion medium is usually substituted by plastic house with branch shape and color on its surface. A set of lamps are located within the plastic house in order to simulate the burning branches vision and another set of silk in blame shape hung above this medium, which waves with air blowing. The light source is disposed on the bottom of the interior of the housing, underneath the flame simulation device and between the viewing screen and the rear of the housing. The light emitted by the light source bounces off of the flame simulation device and projects the image of the flame simulation device onto the viewing screen. The simulated fuel source, which is typically shaped as one or more wooden logs, is disposed adjacent to the viewing screen and positioned such that it appears the flames projected on the screen are emanating from the logs. The simulated fuel source additionally serves to conceal the operation of the light source and flame simulation device.
