A humidification and air cleaning apparatus is provided, in which a wave having a predetermined cycle is formed on a plurality of blades of a blower fan, such that operating noise caused by a flow of discharged air may be minimized, and a wave is formed at a trailing edge, such that a phase difference may be formed for air to be separated, and air flow noise of the discharged air may be reduced.

The present invention is related in general to air circulators, and in particular, to an air circulator with a vein control system to direct and adjust airflow patterns. According to an exemplary embodiment, the present invention provides adjustable, vertical veins that are attached to the outlet of a tower fan. According to a preferred embodiment, the veins are pivotally mounted in such a way that by turning a knob, the veins can either be directed into a focused air-flow pattern or adjusted to a divergent air-flow pattern, or at any setting in between.

A portable air purifier may include an inlet configured to form a path along which air is suctioned, a filter disposed at an upper side of the inlet and configured to purify air which enters through the inlet and moves upward, a sanitizing portion disposed at a lower side of the filter, installed at a height allowing the sanitizing portion to overlap the inlet, and configured to irradiate sanitizing light toward the filter, and a fan module disposed at an upper side of the filter and configured to rotate a fan to blow air in a direction toward the upper side of the filter.

A fan assembly (10) includes a shrouded fan rotor (18) having a plurality of fan blades (22) extending from a rotor hub (24) and rotatable about a central axis (20) of the fan assembly, and a fan shroud (26) extending circumferentially around the fan rotor (18) and secured to an outer tip diameter of the plurality of fan blades (22). A fan casing (16) encloses the shrouded fan rotor (18). The fan casing (16) defines a fan inlet (30) of the fan assembly and includes an inlet extension (54) at an outer diameter of the fan casing, extending axially upstream of a conventional bell mouth inlet (58), relative to a direction of airflow through the shrouded fan rotor (18).
