Abstract: Provided are a steam spraying apparatus and a clothing drying machine including the same. The steam spraying apparatus include a flow passage forming unit, a steam generating heater, and a nozzle. The flow passage forming unit has a flow passage for guiding water introduced through an inlet to an outlet. The steam generating heater applies heat to water flowing along the flow passage. A nozzle sprays steam generated by the heating of the steam generating heater at a certain pressure.

Abstract: The dust collector, that may be used in vacuum cleaner, includes: a primary cyclone unit separating dust from air introduced from outside the dust collector; and a secondary cyclone unit defining axial cyclone bodies separating fine dust from air introduced in an axial direction. The secondary cyclone unit includes casings having outer walls around hollow portions; and a fine dust separating member disposed on the casings to form the axial cyclones. The fine dust separating member includes vortex finders disposed in the casings; band portions enclosing an outer circumferential surface of the vortex finders at a position spaced from the vortex finders, and having a shape corresponding to the casings so as to form the axial cyclones together with the casings; and guide vanes disposed between the vortex finders and the band portions and extending in a spiral direction to induce a rotational flow of air.

Abstract: A dust collector includes a primary cyclone unit to separate dust from air introduced from outside dust collector and a secondary cyclone unit includes axial cyclones which separate fine dust from air introduced in an axial direction. The secondary cyclone unit includes a first group of axial cyclones disposed along a circumference of a first circle so as to contact an inner circumferential surface of an inner case, and formed to be partially spaced apart from the inner circumferential surface of the inner case to form first passages therebetween; and a second group of axial cyclones disposed to contact each other along a circumference of a second circle concentric with the first circle and smaller than the first circle, and formed to contact some of the first group of axial cyclones and to be spaced apart from others of the first group axial cyclones to form second passages therebetween.
