Abstract: An air purifier includes: a body having an inlet introducing air; a blower accommodated in the body and providing blowing force for flow of air; a filter filtering the air introduced into the body; a wind direction control unit adjusting a filtered air discharging direction; a manipulation module for outputting a signal manipulated by user; and a control device controlling the wind direction control unit based on the signal. The wind direction control unit includes: a wind direction control member rotating about the body about an axis extending horizontally; a motor providing driving force for rotating the wind direction control member; a driving gear rotated by the driving force of the motor; and a driven gear rotated by the driving gear. The control device controls the motor so that when the driving gear is rotated and then stopped, the driving gear is stopped after reversely rotated by a predetermined angle.

Abstract: The present disclosure relates to an air purifier and, more particularly, to an air purifier capable of introducing a filter support structure including a first body supporting a filter member and having a protruding part on a lower surface thereof, and a second body disposed at a lower portion of the first body and having a groove part having an inclined surface in contact with the protruding part formed at one side thereof, thereby allowing the filter member drawn out of the housing to be inserted into an inner space of the housing and simultaneously moving the filter member upward to form a sealing against a latching part, thereby enhancing convenience of filter management and improving air tightness of the filter member.

Abstract: An air purifier includes a filter member for filtering pollutants in the air, a blower for providing blowing force to allow the air to pass through the filter member, a body frame accommodating the blower, a cover frame that forms a part of an appearance of the air purifier and is detachably coupled to the body frame, and a filter frame that is detachably coupled to the cover frame and detachably supports at least a portion of the filter member. When the filter frame is coupled to the cover frame, the filter member is positioned between the cover frame and the filter frame so that movement of the filter member is restricted, and when the cover frame is attached to and detached from the body frame, the filter member and the filter frame are attached and detached together with the cover frame.

Abstract: A filter frame includes a support supporting a filter member, and the support includes a first support and a second support which are rotatably connected. Each of the first and second support includes a body part including a first vertical member, a horizontal member having one end perpendicularly connected to the first vertical member, and a second vertical member connected to the other end of the horizontal member, a cylindrical shaft part connected to the first vertical member, a rotating part connected to the second vertical member to surround a portion of the shaft part, a locking part provided on one of the first vertical member and the shaft part, and an engaging part provided on one of the second vertical member and the rotating part and engaged and fixed to the locking part. The rotating part of the second support is coupled to the shaft part.

Abstract: A composite filter includes a filter unit including a filter member having filtering parts, at least one filter module arranged in parallel with at least one of the filtering parts, and a bracket supporting the filtering parts disposed adjacent to each other and the filter module so that the filtering parts disposed adjacent to each other are rotatable. The bracket includes a folded portion that is selectively folded according to the relative rotation of the filtering parts, and attachment portions connected to the folded portion with the folded portion interposed therebetween, and attached to the side surfaces of the filtering parts disposed adjacent to each other. The folded portion and the attachment portions are provided integrally and are formed of a flexible material, and the attachment portion extend to the side surface of the filter module adjacent thereto to seal a gap between the filtering part and the filter module.

Abstract: An air purifier has an air filter including: a filter member including a plurality of filtration regions each having a plurality of vertical pleats extending in an up-down direction and side surfaces connected to be rotatable with respect to each other; and a frame having a plurality of supports for supporting the plurality of filtration regions. Each of the plurality of supports includes a groove having a shape corresponding to any one of an upper edge and a lower edge of each of the filtration regions. Each of the filtration regions is supported by the supports by at least a part of the upper edge or the lower edge being inserted into the groove.

Abstract: Disclosed is a humidifying air cleaner comprising: a housing having an inner space and having a barrier member for delimiting the inner space; and a humidification unit installed on the housing to be arranged on the lower portion of the barrier member, wherein the barrier member has a first air inlet, behind which the humidification unit is arranged, and which is formed such that air flows into the humidification unit, and a second air inlet formed to be arranged above the first air inlet, and the barrier member is provided with a rib for increasing the amount of air flowing through the first air inlet.
