Abstract: An air cleaner is provided that may include a first air cleaning module having a first fan that generates air flow from a first suction inlet toward a first discharge outlet; a second air cleaning module having a second fan that generates air flow from a second suction inlet toward a second discharge outlet; a dividing plate provided between the first air cleaning module and the second air cleaning module; and a display provided at inside of the dividing plate and in which a light source is provided.

Abstract: An air cleaner is provided that may include a first air cleaning module including a first fan that generates air flow toward a first discharge outlet from a first suction inlet; a second air cleaning module including a second fan that generates air flow toward a second discharge outlet from a second suction inlet; and a divider provided between the first air cleaning module and the second air cleaning module, the divider being configured to block air discharged through the first discharge outlet from being suctioned into the second suction inlet.

Abstract: An air cleaner and a method for controlling an air cleaner are provided. The air cleaner may include a first air cleaning module having a first fan and a first filter; a second air cleaning module having a second fan and a second filter, the second air cleaning module provided vertically over the first air cleaning module; an air flow controller provided at an upper side of the second air cleaning module and including a circulation fan; a sensor configured to sense a pollution level in a room space; an input configured to receive input of a command for an operation mode of a plurality of operation modes to operate the first and second air cleaning modules and the air flow controller; and a controller configured to drive at least one of the first fan, the second fan, or the circulation fan selectively and determine an amount of discharge air flow.

Abstract: An air cleaner is provided. The air cleaner may include at least one air cleaning module including a fan, a filter and an inlet through which air is suctioned into the filter; an air flow controller configured to be movably disposed on the at least one air cleaning module and including an air flow control fan to control a flow of the air discharged from the at least one air cleaning module. The air flow controller may be movable from a first position at which the air is discharged in an upward direction to a second position at which the air is discharged in a diagonally upward direction.

Abstract: An air cleaner is provided that may include a case including a first suction inlet, the case having a cylindrical or cone shape; a fan housing provided inside of the case, the fan housing accommodating a fan therein; a filter provided at a suction side of the fan, the filter filtering foreign materials in air which is suctioned through the first suction inlet; and a housing suction flow path formed between an outer surface of the fan housing and an inner surface of the case, the housing suction flow path allowing air which is suctioned through the first suction inlet to flow toward and through the filter. The housing suction flow path may include a first flow path inlet having a predetermined first width, and a second flow path inlet through which air having passed through the first flow path inlet flows, the second flow path inlet having a second width greater than the first width.

Abstract: An air flow controller for an air cleaner and an air cleaner are provided. The air flow controller may include a fan, and a housing, the fan being provided in the housing and the housing being movable from an initial horizontal position in which the air flow controller directs air flow in a vertical direction to an inclined position in which the air flow controller directs air flow in a diagonal direction.

Abstract: Disclosed is an air conditioner. The air conditioner includes a main body having a blower fan to circulate air, a rotator rotatably provided in the main body, a tray provided in the main body to store humidifying water therein, and a humidifying gear module provided at a periphery thereof with a lifter connected to the rotator, the humidifying gear module being rotatably arranged in the tray so as to be rotated upon receiving rotational force of the rotator. The lifter of the humidifying gear module functions to scoop up the humidifying water during rotation of the rotator.

Abstract: Disclosed is an air conditioner. The air conditioner includes a tray in which humidifying water is stored by a predetermined height, the tray being detachably attached to a main body, a humidifying gear rotatably arranged in the tray so as to be detachably attached to the tray, a lifter provided at a periphery of the humidifying gear, the lifter being submerged under the humidifying water so as to scoop up the humidifying water during rotation of the humidifying gear, and a humidifying filter provided in the humidifying gear and spaced apart from the humidifying water such that the humidifying water is supplied from the lifter to the humidifying filter during rotation of the humidifying gear.
