WIND-RESISTANT OUTDOOR HEATING APPLIANCE

摘要

WIND-RESISTANT OUTDOOR HEATING APPLIANCE An outdoor heating appliance includes a top structure having a top surface, a stationary airfoil, and exhaust openings for flue products. The operation of the heating appliance is rendered wind resistant by generating with the stationary airfoil, in a region above the top surface and in response to wind, an air pressure lower than an air pressure of that wind, and by locating the exhaust openings in that region, whereby the flue products axe exhausted from the outdoor heating appliance by the wind. An inlet opening may be provided below the top surface at the airfoil for receiving part of the wind, in order to sustain combustion and generate inside the heating appliance positive pressure toward the exhaust openings by guiding air from the received part of the wind through a channel to a burner in the heating appliance.
