An apparatus for flame simulation in an electrical fireplace which improves the realism of leaping and flickering flames, comprising a fixed light source, simulated charcoal, and a flame display screen which is arranged above the fixed light source. The simulated charcoal is located in front of the flame display screen. A twisted-style light reflector is located behind the flame display screen and is driven by a motor mounted inside the wall of the electrical fireplace. By rotating the twisted-style light reflector, light emitted from the fixed light source is reflected onto the flame display screen so the simulated dynamic leaping and flickering flames can be seen. The fixed light source also illuminates the simulated charcoal to produce an effect of burning charcoals. A heater produces warm air that is expelled from the fireplace.

The heating element positioned above the first structural layer. The plurality of intermediate strips are mounted upon the first structural layer. Each intermediate strip is positioned proximate at least one of one the first layer edge and the heating element. The second structural layer is mounted to the plurality of intermediate strips opposite the first structural layer.

An underlayment system is provided that includes a plurality of bosses that emanate from a common base member. The bosses and bases preferably include an opening therethrough that will allow for subsequent layers of adhesive to interact and bond to each other. The bosses are also spaced in such a way to help secure a wire snugly therebetween.

An aircraft floor heating panel is constructed for mechanical strength and to meet special heating requirements next to a door in an aircraft. The panel has a lightweight core. Each surface of the core is first covered with at least one carbon-fiber reinforced composite layer for protection against deterioration. Each carbon fiber layer in turn is covered by a glass fiber reinforced composite layer for mechanical strength. A foil heater is arranged inside the composite panel coextensive with at least a portion of the panel area. A heat distributing metal plate covers the panel as an upper step-on surface. A heat insulating layer is bonded to the panel opposite the heat distributing metal plate. A triple heat control is provided for an increased safety against fire hazards.

A flame imitation manufacturing device of a fireplace relates to a flame imitation manufacturing device for simulating the burning state in a fireplace in the field of household appliances. Said device comprises a housing, a cross flow fan and a light source mounted on a base plate of the housing, a simulated fire chamber mounted on a back plate of the housing, ribbons mounted on the back plate of the housing by means of upper and lower strip bars and above the cross flow fan, and a light-transmitting glass plate mounted on the housing and in front of said ribbons. This invention, characterized in that said cross flow fan is a swinging one, is advantageous in that supplying wind non-directively by utilizing the swinging of said fan improves the flying state of ribbons so as to make the image state of burning flames more vivid, greatly enhances the authenticity of flames and lowers the cost thereof, and thus is adaptable to various flame imitation electrical-heated fireplaces and electrical appliances.

The invention relates to a molten salt heat storage type electric heating central heating system, and belongs to the technical field of heat storage. The molten salt heat storage type electric heating central heating system comprises a molten salt electric heater, a high-temperature hot salt tank, a low-temperature cold salt tank, a molten salt pump, a molten salt-water heat exchanger and a heat user. During the time period of low-price low off-peak electricity at night, the molten salt in the cold salt tank is pumped out through the molten salt pump to be conveyed to the molten salt electric heater for heating, and enters the hot salt tank after being heated up to high temperature. During the time period of a power utilization peak, the high-temperature molten salt, with accumulated heat, in the hot salt tank is pumped put through the molten salt pump to be conveyed to the molten salt-water heat exchanger and heats water used for municipal heating to produce hot water for supplying heat to residents. On the basis of a coal-fired boiler central heating system which is in general use at present, only a boiler room of the central heating system needs to be transformed into the molten salt heat storage type electric heating system, and neither a municipal heat supply pipe network nor heat supply terminal equipment needs to be transformed. Besides, the molten salt heat storage type electric heating central heating system can cut down a peak to supplement a trough and reduce the usage amount of coal, thereby playing a role in protecting the environment.

A cloth heater and method for using the heater are provided. The heater utilizes a horizontally disposed surface, a heated glass panel, and support members. The horizontally disposed surface may comprise the top edge or surface of the heated glass panel, or a surface on a separate rack that is above and vertically inline with the top edge of the heated glass panel. The heated glass panel also has two opposing major surfaces. The support members physically support the heated glass panel and have electrical leads that communicate electrical power to the heated glass panel, thus heating the heated glass panel. When a cloth is placed across the horizontally disposed surface, the horizontally disposed surface supports the cloth, and the cloth makes contact with the two opposing major surfaces of the heated glass panel, thus heating the cloth at both opposing major surfaces.

The invention discloses a non-nail clamped electric heating floor system which is characterized by comprising electric heating floors, mounting bases, power supply keels, inserting piece clips, copper conductors, connecting pieces and connecting wires. The installation method of the non-nail clamped electric heating floor system comprises the following steps: firstly the power supply keels are laid on the floor along the side of the rear wall of the laid room in the length direction; the mounting bases are laid on the floor in the mode that the length direction of the mounting bases are perpendicular to that of the power supply keels, the mounting bases are parallel to one another, and plate-end transverse clamping parts and middle transverse locating parts of two neighboring mounting bases are correspondingly arranged at front and back positions; the electric heating floors are vertically fixed on the mounting bases; and finally the electric heating floors work in parallel, i.e. all the electric heating floors emit heat for warming purpose while switching on a power supply, and other electric heating floors are not affected even though certain floor is damaged.

The present invention relates to a novel constructional principle for electric heaters, wherein the functions of frame and resilient means are separated from one another. As a frame for an electric heater, a housing is used that consists of two half-shells. Positioning aids for the PTC heating elements are arranged in the housing. The longitudinal sides of the housing are essentially made open to allow for air throughput through the heating register. A resilient device is additionally inserted into the housing, the resilient device compressing the layered structure of radiator elements, PTC heating elements and contact sheets. After the heater has been assembled, the resilient device can be inserted through a lateral opening into the heater.
