A window mounted oscillating fan. The fan has two blower modules each having a motor, fan blade, and diffuser. The diffuser is fixed in a stationary position relative to its fan blade. The window fan oscillates by pivoting all blower modules simultaneously through a single motorized oscillation mechanism. The blower units may be arranged to discharge air in parallel, or alternatively, in different directions. The blower units pivot about an axis inclined from the vertical, so that oscillation has a vertical component as well as horizontal. In different embodiments, the fans operate in tandem, facing the same direction at all times, or oscillate in different directions, thereby diffusing incoming air. The window fan has an air filter, and manual and automatic controls including a touch sensitive on-off switch, a thermostatic on-off switch, and a speed selector.

Oscillating window fan

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.

A positive temperature coefficient (PTC) heater includes a housing, a fan mounted within the housing, a pair of positive temperature coefficient (PTC) heater assemblies disposed in the housing, and a plenum mounted in the housing. The housing includes a front portion and a rear portion connected together to define a front, a rear, a left side and a right side, the front and rear each having at least one opening. The fan is arranged to produce a flow of air from the rear of the housing to the front. The pair of positive temperature coefficient (PTC) heater assemblies are disposed in side by side relationship and angled relative to each other, each at an angle of approximately 7.5 degrees from normal, so as to produce a diverging column of heated air. The plenum mounted in the housing directs the air flow produced by the fan through each of the PTC heater assemblies.
