    Abstract: The inventive warmer apparatus comprises a holding unit, enclosed on four sides, but open at the top to allow restaurants and kitchen operators easy access to food held in it. Food in the apparatus is exposed to radiant heat generated by a heated bottom surface and to hot convection air. Part of the convection air is used to create an air curtain to improve heat loss characteristics and protect from the environment. The apparatus uses a combination of radiant heat, convection air and a warm air curtain to keep food products hot and crisp. The air curtain provides additional food protection. The warmer apparatus conditions food to attain a noncooking biologically safe temperature and to retain its freshly cooked texture and internal moisture for at least twenty minutes. This allows restaurants to serve such food items longer to its customers, allowing more efficient batch cooking and significantly reducing food waste.

  • Patent number: 8107797
    Abstract: The present invention discloses a reflection heating fan comprising at least one fan rotating over a main axle, at least one heating element and at least one reflector, said heating element and reflector are continuing from said main axle, wherein said heating element indirectly heats an air stream by reflecting heat produced by a heating element into the air stream produced by said fan. The present invention also discloses a method of indirectly heating a stream of air, comprising applying energy to a heat emitting element incorporated into a bi-functional rotation axle, reflecting said energy by means of a reflective surface into an air stream produced by applying rotation to a bladed fan structure, achieved by transferring the power from a motor through the bi-functional axle to at least one bladed fan structure.

  • Patent number: 8101890
    Abstract: A fan apparency arrangement for an appliance having a fan for moving air in an interior of the appliance, including a pipe disposed in the airflow path of the fan and having first and second ends; a heater disposed in the pipe, the heater being energized when the fan is turned on; and a thermal switch disposed in the pipe, the thermal switch being closer to the first end than the heater. The fan is operative in normal operation to move air in the pipe in a direction from the first end to the second end. The pipe is disposed so that when the fan fails to move air in the pipe after turned on, air heated up by the heater passes the thermal switch in a direction from the second end to the first end so that the thermal switch is activated to signal malfunction of the fan.

  • Patent number: 8081872
    Abstract: 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.

    Abstract: An adaptive heating system for optimizing energy resources while heating a confined area. The adaptive heating system includes at least the following components: a controller, a first heat source, a switch device, and a wireline system. The wireline system is configured to connect the controller to the first heat source, a second heat source, and the switch device. The controller is configured to receive an input from the switch device, determine whether the input indicates a selection of the first heat source or a selection of the second heat source, and then initiate operation of either the first or the second heat source, based on the determined selection. The first heat source is associated with an electric heater and the second heat source is associated with a gas furnace.

  • Patent number: 8019207
    Abstract: 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 space heater includes a first panel, a second panel, and an element having one or more heatable surfaces. The second panel is coupled to the first panel and the element is located therebetween to define the chimneys between the first panel and the second panel. The element has the one or more heatable surfaces located within the chimneys. When activated, the one or more heatable surfaces create thermal energy for generating heated air within the chimneys, the heated air flowing by convection substantially upwardly through the chimneys to provide the heated air to the area adjoining the space heater.

  • Patent number: 7925143
    Abstract: An apparatus to heat potable water aboard a recreational marine watercraft includes a metal enclosure that sits atop one burner of a conventional galley stove powered separately from the engine and the source of AC power. Potable water is circulated through a tubing unit mounted within the enclosure by a pump operated by a low DC voltage. The heated potable water is then transferred back to the potable water holding tank through a check valve which prevents reversed flow of the heated water. This provides a boater with the ability to maintain a source of hot water while away from shore power or while the engine is turned off. The top of the enclosure is partially open to allow use of the burner for cooking, or boiling water as needed with the cooking vessel being placed atop of the enclosure.

    Abstract: An electric heater includes primarily an S-shaped air channel which is provided in a body, at least one heating unit which is provided in the air channel, and at least one heat energy conversion unit which is close to an inner wall of the air channel and close to the heating unit. An interior of the heat energy conversion unit is defined with a passage. Hot air can be directed rapidly by a principle that hot air ascends, through the S-shaped air channel. Heat energy produced by the heating unit is absorbed by the heat energy conversion unit and is then carried away by an air power of the passage, so as to achieve effects of heat accumulation and dissipation.
