The blower unit and the heat exchange unit are located in a substantially same lateral dimension in the cabinet.

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.

Abstract: A portable, low profile electric radiant heater has an elongated heating element. A plurality of thermistors are disposed proximate to and along the length of the elongated heating element, spaced at substantially equal intervals. A microcontroller switches a reference resistor in series with a charging capacitor to determine a reference timer value. The microcontroller switches banks of multiple thermistors in series with the charging capacitor to determine associated timer values. The microcontroller calculates thermistor resistance values using the reference timer, reference resistor, and thermistor timer values. A lookup table is employed to determine a temperature value associated with the thermistor resistance value. This serves as the sensed temperature of the associated bank of thermistors. A plurality of tip-over switches are provided. One tip-over switch is disposed between the microcontroller and the heating element.

Abstract: In one embodiment a blow dryer includes a barrel having an opening. A deflector, having an aperture, positioned within or substantially within the barrel. The hand-held blow dryer can be utilized in at least a first or open mode in which air flow is directed through the barrel opening of the barrel, and a final or fully deflecting mode. Thus, in the fully deflecting mode most of the air is deflected by the deflector so as to diffuse the airflow. Additionally, the shape of the deflector allows the airflow to be maintained while the deflector is in any position, thus, allowing the airflow to flow past the heating coils in the barrel so that potential overheating of the blow dryer is reduced. In another embodiment, a gap is provided between two flaps which comprise the deflector so as to achieve the same result. In still another embodiment, rings are provided around the circumference of a barrel having holes in the barrel. The rings diffuse the air emanating out of the holes and also guide the hair for styling.

Abstract: A portable forced air space heater having a three hundred sixty degree peripheral dispersion pattern. The heater has a tubular housing and a fan forcing air past a heating element upwardly within the housing. The air encounters a conical deflector which redirects the air to flow outwardly at the top of the housing. One or more movable baffles are selectively placed in the housing so as to obstruct discharge of air at various selected sections of the peripheral pattern of discharge. This feature prevents injurious or otherwise objectionable discharge of heat when the heater is placed close to another object. The baffles are arcuate, so that they cooperate with the tubular housing, and insulated to minimize propogation of heat to the obstructed portion of the discharge pattern. Baffles are removable from the heater, and are maneuvered for adjusting their position from outside the heater.

Abstract: A drying apparatus such as a hand-held hair dryer comprising a housing including a nozzle and containing an air outlet and a fan assembly contained within the housing for generating a flow of air from the outlet. The apparatus further includes a flow guide including a plurality of holes therein contained within the nozzle, the flow guide forming a closed shape in cross-section and having open ends. The flow guide is separated from the nozzle so as to form a space between the nozzle and the flow guide for flow of air therethrough. The flow guide tends to attenuate noise generated by operation of the apparatus by lowering the frequency of the noise.

Consequently, the components of the air supply unit, the coupling hose and the dryer head may all be constructed of economical plastics without component failure due to heat degradation.
