  • Patent number: 5997674
    Abstract: An air purifier, an air filter and a method of manufacturing an air filter for an air purifier are provided. The air purifier includes a base assembly, a filter assembly and a grill. A fan is mounted to the base assembly, and draws air through the filter assembly. The base and filter assemblies include adjoining walls having openings which are substantially smaller in area than the areas of the adjoining walls and area through which air is drawn in through the filter assembly. A resilient gasket having a passage approximately the size of these openings is positioned between the adjoining walls. The filter assembly is drawn towards the base assembly when the fan is operated, thereby enhancing the seal formed by the gasket against the adjoining walls. Unfiltered air is accordingly unlikely to bypass the filter assembly. The air filter is manufactured in an efficient manner through the use of a back plate having oblique end portions.

  • Patent number: 5761377
    Abstract: A portable heater providing both radiant and forced air heat includes a plurality of vertically oriented, horizontally spaced apart quartz heating tubes is partially surrounded by a common reflector configured to open at an obtuse angle at each quartz tube. The reflector is perforated to allow air to pass out from the interior of the heater. A housing surrounds the reflector and heating elements. A fan located toward the top of the heater draws air inward and down the channels behind the reflector from which it emerges past the heating elements. Control knobs for controlling a thermostat and output power level are located at the top surface of the housing. The heater also has automatic safety controls for shutting off power in the event the heater tips over or overheats, and an overcurrent device.

  • Patent number: 5660605
    Abstract: A window fan incorporating a filter. The fan has a low, flat profile for fitting in a window while occupying limited viewing area of the window. The fan includes laterally projecting extensions for sealing a gap which might otherwise exist at the right and left sides of the fan. The fan includes a motorized squirrel cage blower for forcing air through a flow path defined within the window fan. The blower is elongated, and oriented with its rotational axis arranged horizontally to enable the low profile. The filter is washable, and is installed by sliding into a holding chamber, and located serially within the air flow path. The window fan has a manually adjustable air deflector for directing discharged air as desired. The electrical circuit conducting power to the motor includes a touch sensitive switch for on-off control, a thermostatic switch for operating the fan when the touch switch is on and a predetermined temperature is detected, a speed selector switch, and an indicating lamp.
