Abstract
An electric fan assembly comprises a generally cylindrical cross-flow fan, a rear guider, and a stabilizer. The rear guider has a downstream edge with respect to the direction of flow of an air current and is hingedly connected with a pivotable plate. By the utilization of the adherence effect of the air current to the pivotable plate, the direction of flow of the air current is controlled by pivoting the pivotable plate. In other words a slight pivotal movement of the pivotable plate is sufficient to bring about the deflection of the air current over a relatively large angle. The fan assembly may be employed in an air-conditioner in which case a relatively high air-conditioning efficiency can be obtained.
