  • Patent number: 10221860
    Abstract: A bladeless fan assembly for creating an air current includes a nozzle mounted on a base. The nozzle comprises an interior passage and a mouth for receiving the air flow from the interior passage and through which the air flow is emitted from the fan assembly. The nozzle defines an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The nozzle is detachable from the base, which is preferably sized to be accommodated within the opening of the nozzle for transportation.

    Abstract: A heating and ventilating fan including a frame, a motor with fan blades, a casing, a heating device, and an air path switching plate disposed at an air outlet of the casing for switching outlets of the ventilating fan and a timing motor. The timing motor and the air path switching plate are fixed on either side of a frame wall. The air path switching plate is connected to the timing motor shaft through a connection part, and controls the air path switching plate to rotate by a constant angle in a single direction. A spring having a first end fixed to the frame wall, and a second end rotating synchronously with the air path switching plate controls the air path switching plate to rotate in an opposite direction to the single direction. When the timing motor is switched off, the spring returns the air path switching plate to its rest position.

  • Patent number: 8467668
    Abstract: An infrared, room heater system for installation in a wall or on a floor. An electric fan assembly draws room air into a housing, then through three parallel, air transit channels where the air is heated by infrared radiation within and about a heat exchanger assembly, and then back out into the room. One or more ceramic heating elements attached to a first copper plate emit infrared radiation when electrically energized. The first copper plate lies adjacent to, but spaced away from, a second copper plate such that radiation emitted from the heating elements reflects back and forth between the plates. Room air passed between the copper plates is heated by heat radiation concentrated between the plates, thereby achieving both energy and space efficiency.

  • Patent number: 6907192
    Abstract: If both the electric heaters and combustion heaters constitute a hybrid type hot-air heater wherein both heaters are equipped with inlets adjacent to each other and are also housed within a frame and separated such that the air blowing systems of each heater are independent of each other, air leakage will occur in only the combustion heater during the heating operation in a direction opposite to the air blowing passage of the electric heater thereby resulting in dust adhering to the electric heater. If the electric heater is operated in this state, the dust will be heated and then burn causing a foul odor to occur when the heating operation first starts. Therefore, the air blowing fan 43 runs to remove any dust that entered into the air blowing passage before the electric heater 4 runs when the electric heater unit 4, equipped with an electric heater 44, is performing a heating operation.

    Abstract: A portable electric heater for providing a heated exhaust air stream at an elevation above a support surface is provided. The heater comprises an elongate housing having a sidewall, a top end, a bottom end, and a longitudinal length extending substantially upward from the bottom end to the top end, and a horizontal cross sectional area. A base supports the elongate housing in a vertical and upright position on the support surface. There is at least one inlet opening in the housing allowing inlet air to enter the interior of the housing. An air blower assembly is disposed within the housing interior for receiving the inlet air. At least one outlet opening in the elongate housing allows the exhaust air stream to exit the interior space. At least one electric heating element is disposed within the interior space between the air blower assembly and the outlet opening.

  • Patent number: 6795643
    Abstract: When errors occurred that prevented operation of one heater unit in a conventional hybrid type hotair heater, the heating operation was continued by means of the other heater unit although the user could not immediately recognize that error thereby resulting in the possibility that the error condition might remain in the hotair heater. Therefore, an error detection means was installed in each gas and electric heater unit to detect errors that prevent heating operation in each of these heater units. When an error is detected in one heater unit during the heating operation by means of said error detection means, the heating operation of the device stops once. When the operation starts up again, the other heater unit, where said error did not occur, runs and the heating operation continues.

  • Patent number: 6674049
    Abstract: A storage drum heater has an elongated housing and is typically used in a vertical orientation between storage drums arranged on a pallet. In one embodiment, the housing has closed ends and vertical sides that intersect four vertical, diagonal surfaces at their vertical edges. A column of holes is located in each diagonal surface, upper holes being axially spaced from lower holes. The housing contains a blower fan and a resistive heating element for heating air expelled by the blower. A battery is located in the housing and provides electrical power for operating the fan and the heating element. The fan draws air into the housing through the lower holes, then blows the air across the heating element and out of the housing through the upper holes, preferably into the V-shaped interstitial space between drums.

  • Patent number: 6624397
    Abstract: A heater effectively uses a current controlled fan motor in series with a resistance heating arrangement. The fan motor preferably is wound with a gauge of wire to appropriate for the relatively high current provided to the fan motor. This arrangement is effectively used to adjust the fan speed to match the heat output when the heating arrangement has variable heat output. More desirable operating characteristics are achieved without increasing costs and fan motor manufacturing savings are realized. The portable heater preferably produces heat at different outputs and the current used to power the resistance heating arrangement is used to power the fan motor.

    Abstract: A dual source heater with radiant and convection heaters operates to provide radiant and convective heat for heating a surrounding space. A quartz heating element provides radiant heat, and a resistive heating element provides convective heat, through openings in the heater housing. A reflector is positioned so that an airflow updraft is created within the housing and airflow is concentrated through the resistive heating element.

    Abstract: At least one aspect of the present invention relates to a system for heating a gas using positive temperature coefficient (PTC) elements. More particularly, aspects of the present invention are directed towards PTC element configurations and orientations. In one aspect of the present invention, PTC elements are interposed between heat sinks such that they transmit current from one heat sink to another. The PTC elements may be arranged in a radial configuration, which may have more than one PTC element per radial flange. The heat sinks may have grilles which allow air to flow perpendicular to the heat sinks and between the PTC elements.
