    摘要: A cleaner using a heating, ventilating, and air conditioning (HVAC) module is provided. The cleaner connects a ventilation fan for the HVAC module and a suction fan for vacuum cleaning to a single motor to independently drive the ventilation fan when the HVAC module is operated and to independently drive the suction fan when vacuum cleaning is performed. Accordingly, the number of components and production cost are reduced and, simultaneously, package assembly capability is improved.

    摘要: A vent unit includes a bezel installed on a vehicle and formed in a ring shape with a flow hole at the center, and a spacer overlapping and coupled to the bezel and formed in a ring shape rotating relative to the bezel. The bezel has a plurality of first through-holes circumferentially spaced apart from one another, and the spacer has a plurality of second through-holes circumferentially spaced apart from one another such that conditioning air is discharged to an interior through the second through-holes and the first through-holes when the second through-holes are aligned with the first through-holes by circumferential rotation. The vent unit further includes a wing disposed in the flow hole of the bezel and coupled to the spacer through a hinge shaft. The wing controls discharge of conditioning air through the flow hole by axially rotating, and circumferentially relatively rotating together with the spacer.
