Abstract

A fan of the present invention comprises: a case as a frame having an internal space, a first opening formed in the middle thereof, and inlet and outlet holes formed in the inner and outer surfaces of the periphery of the frame; a rotational part with blades mounted in the internal space, the blades being rotated by a power means to draw external air through the inlet holes into the internal space and to discharge it through the outlet holes; and a cover mounted on the front of the case and provided with a second opening communicating with the first opening so as to discharge the air from the inside of the second opening through the outlet holes towards the outside

Description

technical field [0001] The present invention relates generally to an electric fan, and more particularly to an electric fan constructed in such a manner that the impellers are arranged on corresponding peripheral parts of a housing constructed to have a plurality of The polygonal shape of the segments enables to increase the air discharge flow per unit of air flow, thereby increasing the wind intensity. Background technique [0002] Generally, a household electric fan includes a set of blades or fins arranged on a shaft and rotating about the shaft, and a drive unit that rotates the blades to generate air flow. The movement and circulation of the air creates a breeze that cools the user as heat is carried away from the user's skin by convection and evaporation. [0003] Such electric fans can be constructed in a variety of different sizes and shapes. For example, it may be a ceiling fan with a diameter of 1 m or more. Typically, such ceiling fans are suspended from the ce...
