Abstract
An exhaust air hood has a tubular body and at least one plate member having a chamber inside thereof. The plate member has a planar configuration including widths gradually decreasing toward two longitudinal ends of the plate member, the chamber having an opening at each longitudinal end of the plate member. The exhaust air hood discussed is capable of reducing backflows through exhaust air ports caused by wind pressure, thus enabling a proper ventilation system to be achieved.
