摘要： A portable air cleaner comprising a cylindrical filter element mounted on a circular base and encased by a cylindrical cover. A centrifugal fan mounted within the cover draws unpurified air into inlet openings disposed in the base and the side wall of the cover, and through the filter element. The resulting purified air is drawn into the centrifugal fan and forced radially outward therefrom. An air deflector dish redirects the purified air through the exhaust openings disposed on the top surface of the cylindrical cover. Such an exhaust flow which is perpendicular to and spaced from the inlet flow results in an improved efficiency in purifying the entire volume of air within a room.

摘要： A centrifugal blower wheel having an indivisible prime number of peripherally spaced blades projecting upwardly from the top surface of a generally annular-shaped base plate. Each blade includes a tapered portion extending along an inside edge of the blade to approximately 1/3 to 1/2 the length of the blade. A hub is centrally located on the top surface of the base plate and surrounded by the inside edges of the blades, the hub curving upwardly from the top surface of the base plate to form a smoothly contoured curve.

摘要： This invention relates to a filter change indicator that is operable in various orientations of the device incorporating it. For example, the filter change indicator is operable when the device is positioned in either the upright or sideways position. The device incorporating the filter change indicator can be any air moving device which incorporates a cleanable or replaceable filter. The filter change indicator includes a transparent viewing window and a tubulation. The viewing window displays a visible signal when the filter needs changing. The visible signal can be a float retained in the tubulation. The tubulation is a hollow transparent tube which forms an incline plane within the housing. The tubulation includes a first end, a second end and a step. The first end is in fluid communication with an air flow path through the tubulation, and this air flow path is exposed to atmospheric pressure. The second end opens into an air flow path formed between the inlet and outlet at a location downstream of an air filter. When a predetermined pressure differential develops across the tubulation, a predetermined force develops inside the tube which lifts the float from the first end of the tubulation to a position at the second end. The lifting force causes the float to come to rest in the tubulation at a position adjacent the viewing window.

摘要： A portable electric heater including a housing having a bottom wall with front and back portions, a rear wall, a pair of side walls each having front and back portions, a top wall with front and back portions, a divider wall having a given area, and a front grill wall. The rear wall, divider wall and back portions of the bottom, side and top walls define a chamber while the divider wall, the front grill wall, and the front portions of the bottom, side and top walls define a cavity horizontally juxtaposed to the chamber. A plurality of elongated quartz heater elements and a temperature sensor are mounted in the cavity, and an electrically energizable fan is mounted in the chamber. Defined in the rear wall are a plurality of inlet openings, and in the divider wall are a plurality of discharge openings having a combined area equal to less than 2.5% of the given area. Limiting the overall area of the discharge openings reduces in the cavity turbulence which can prevent the detection of hot spots by the temperature sensor.
