Disclosed is an air cleaner, more specifically, an air cleaner including a blower that inhales air from the outside, and filters the inhaled air, and discharges the filtered air, a flow adjusting device disposed on the blower to inhale the air discharged from the blower, adjust a discharge direction of the inhaled air, and discharge the air, and a guide member disposed below the flow adjusting device to change a state of the flow adjusting device. An angle formed between a top surface of the flow adjusting device and a top surface of the blower may increase or decrease based on operations of the plurality of links, so that the state of the flow adjusting device may be changed from an orientation in which the top surface of the flow adjusting device is horizontal with the top surface of the blower to an orientation in which the top surface of the flow adjusting device is perpendicular to the top surface of the blower.

A dynamic register system automatically adjusts venting panels attached to an air vent in order to evenly disperse the air supplied by the vent in a room. The dynamic register system includes a fan internally mounted within the air vent. The air supplied by the air vent causes the fan to turn providing the system with mechanical energy. The fan is then attached to a gear system which in turn is attached to an adapter. The gear system then translates the rotational mechanical energy of the fan into an oscillating motion for the adapter. The adapter is then mounted to an axle which engages with the venting panels attached to the vent. As the adapter oscillates the axle is adjusted which in turn adjusts the venting panels periodically to evenly distribute air.

The present disclosure relates to an indoor unit of an air conditioner, the indoor unit including: a case having an outlet elongated in one direction; a first vane disposed at the outlet; a second vane disposed at the outlet at a position behind the first vane; a drive motor disposed on one side of the outlet and configured to provide a driving force to at least one of the first vane or the second vane; a drive link coupled to a shaft of the drive motor, and having a first end connected to the first vane and a second end connected to the second vane; and a first vane link having a first end connected to the case and a second end connected to an end portion in a longitudinal direction of the first vane, wherein the first vane has a first curvature formed on a surface perpendicular to an air discharge direction and formed in the longitudinal direction, such that the outlet may be tightly closed in response to sagging of a central part of the first vane due to self-weight in a dual vane structure, and in response to torsion that occurs due to a third vane link provided in the dual vane structure.

Disclosed is an air mix valve including: a wall having at least three openings; and at least one airflow-regulating device. The airflow-regulating device includes: at least two shutters placed in the internal volume of the valve, at least one aerodynamic shutter of which is arranged with respect to one of the openings so as to be able to receive an airflow passing through this opening, and a linking mechanism between at least two shutters. Each of the shutters is arranged and guided so as to be able to be caused to move with respect to the wall. At least one airflow-regulating device, named aero-controlled regulation device, is mounted to be freely movable under the effect of aerodynamic energy from airflows passing through the openings.

A drive mechanism is configured to drive a movable member of an air conditioner. The drive mechanism includes a motor, a pinion secured to a rotating shaft of the motor, a rack meshing with the pinion, and a guide. The rack has a driven portion directly or indirectly linked to the movable member. The guide is arranged to guide the rack so that the driven portion can travel in a curved path. The guide has a tube part through which the rack passes.

A diffuser assembly includes a first blade pivotably coupled to a housing and configured to rotate about a first axis and includes second blade pivotably coupled to the housing and configured to rotate about a second axis. The diffuser assembly includes a linkage mechanism coupled to the first blade and the second blade and configured to transition between a first configuration and a second configuration. In the first configuration, the linkage mechanism is configured to induce rotation of the second blade about the second axis in a first direction in response to rotation of the first blade about the first axis in the first direction. In the second configuration, the linkage mechanism is configured to induce rotation of the second blade about the second axis in a second direction, opposite the first direction, in response to rotation of the first blade about the first axis in the first direction.

A control module configured to control operation of a damper assembly includes an air damper configured to be disposed within an air duct and movable between an open end position and a closed end position, the air duct providing conditioned air to a register boot proximate the air duct. The control module includes a control module housing that is securable to the register boot. A controller is disposed within the control module housing and is configured to generate damper position control signals, the controller providing the damper position control signals to the damper assembly via a control cable that operably couples the control module with the damper assembly. An antenna extends from the control module housing and is operably coupled to the controller, and is configured to extend through an opening formed within a wall of the register boot to be positioned exterior to the register boot.

A blade adjustment mechanism and an air circulator. The air circulator includes a housing defining an air outlet, and the air outlet includes an air inlet side and an air outlet side. The blade adjustment mechanism includes: a fixing bracket, fixedly connected with the housing; at least two wind guide assemblies, spaced apart from each other and partially extending into the air outlet, rotationally connected with the fixing bracket; at least two first connecting rods, rotationally connected with the at least two wind guide assemblies located, extension lines of the at least two first connecting rods along length directions of the at least two first connecting rods being configured to intersect; and a second connecting rod, fixedly connected with an end of each of the at least two first connecting rod.

A damper adjusting arrangement configured for regulating the flow of a gaseous fluid within a channel (5) of an extractor tubing. The damper adjusting arrangement includes a damper member pivotably arranged in the channel and coupled to a rotary control means of the damper adjusting arrangement. A first member of the rotary control means includes a resilient element, which exhibits a plurality of radially protruding first bulges being configured for engagement with a second member of the rotary control means.

An air handling device includes a plurality of tunnels defining a plurality of separate air flow pathways. At least one tunnel of the plurality of tunnels is an active tunnel and at least one tunnel of the plurality of tunnels is a redundant tunnel. The air handling device further includes a first air select at a first end of the plurality of tunnels and a second air select on a second end of the plurality of tunnels, wherein the first end is opposite to the second end. The air handling device also includes a plurality of dampers within each of the first and second air selects, wherein the plurality of dampers are configured to change an air flow therein to block air flow through the active tunnel and allow air flow through the redundant tunnel.
