Abstract
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.
