ELECTRIC FAN ASSEMBLY

摘要

ELECTRIC FAN ASSEMBLY An electric fan assembly comprises a generally cylindrical cross-flow fan, a rear guide and a stabilizer. The rear guide has a downstream edge with respect to the direction of flow of air to which a plate is hingedly connected. By using the adherence effect of the air current to this plate, the direction of the air current is controlled by pivoting the plate. A relatively slight pivotal movement of the plate is sufficient to bring a larger deflection of the air current. The assembly can be employed in a heater or air-conditioner in which case a relatively high efficiency can be appreciated, with relatively little change in overall flow arising from changes in the angle of deflection.
