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.

An air conditioner indoor unit and an air conditioner are provided. The indoor unit has a surface frame, a breezeless member, a heat exchanger and a fan. A first air outlet is formed in a front lower part of the surface frame. At least one second air outlet is formed on at least one of a left side of the surface frame and a right side of the surface frame. The breezeless member is disposed on a front side of the surface frame and movable between a first position and a second position. When the breezeless member is located at the first position, the first panel opens the first air outlet. When the breezeless member is located at the second position, the first panel closes the first air outlet.

Disclosed is an air cleaner comprising: a housing (H); an air-purifying filter (20); a blowing unit (30); and a channel switching member (200) for switching a discharge channel such that air supplied from the blowing unit (30) flows to at least one of a first discharge port (A51) to discharge air in a first direction and the second discharge port (A52) to discharge air in a second direction. The channel switching member (200) comprises: an elevating member (210) having a first communication unit (216) that is open such that air flows to a first discharge port-side channel (A3), and having a blocking unit (215) for blocking a flow thereof to a second discharge port-side channel (A4); and an opening/closing member (220). The first discharge port-side channel (A3) and the second discharge port-side channel (A4) are opened/closed by ascending/descending of the elevating member (210) and moving of the opening/closing member (220).

A regulating flap reduction gear for an electrically driven regulating flap for regulating a gas or liquid volume flow includes two parallel bearing plates between which gear parts are rotatably arranged. A plurality of spacers keep the two bearing plates at a distance from one another. The plurality of spacers are designed as tabs of one, first bearing plate, which are bent by 90° from the plane of the first bearing plate and have at least one lateral projection. The tabs are inserted with their free tab ends into plug-in openings of the other second bearing plate until their at least one lateral projection rests against the second bearing plate.

Disclosed herein is an air conditioner capable of guiding air in a desired direction with an adjusted speed without marring the appearance to solve the above-described problems. An air conditioner comprising a ceiling-embedded type indoor unit configured to discharge air into an indoor room through an air outlet simultaneously sucking indoor air through an air inlet, wherein a air conditioner comprises, a main flap configured to guide a direction of air discharged from a air outlet in a preset direction, and a sub-flap configured to guide the direction of air between the main flap and the sub-flap in the preset direction, wherein a length of a main flap in a direction where air flows is longer than that of the sub-flap in the direction where air flows.

Various embodiments of the teachings herein include an actuating drive comprising: a drive element; an actuation element; and a restoring spring. The drive element drives the actuation element indirectly about an actuation axis. The actuation element includes a shaft portion concentric to the actuation axis and extends at least partially circumferentially. The restoring spring includes a wound flat spring providing a restoring torque on the actuation element, acting tangentially on the shaft portion, and a free spring end tangentially fastened to the shaft portion. The free spring end is radially externally disposed with respect to the spring axis and fastened tangentially to the shaft portion. The spring is mounted rotatably so the spring axis is radially spaced apart from the actuation axis and aligned parallel to the actuation axis.

An adjustment mechanism (7) for an air vent (5), which adjustment mechanism is adapted to guide an air stream flowing through the air vent. The adjustment mechanism comprises one or more adjustable first vanes (17) having a main extension in a first direction (D.sub.1), one or more adjustable second vanes (19) having a main extension in a second direction (D.sub.2) being angled to the first direction, a shaft (23) extending in the first direction and being rotatable around its length axis, a slider (47) being movably attached to the shaft, such that the slider is able to slide along the shaft in the first direction, and a rack (45), extending in parallel to the shaft and a pinion (41), rigidly connected to one of the second vanes and configured to cooperate with the rack.

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.

A serviceable actuation arrangement for an active grille shutter system. The serviceable actuation arrangement includes a linkage connected to all of the vanes of the active grille shutter system. The linkage is connected to an actuator and moves vertically to rotate the vanes between an open position and a closed position. Between the actuator and the linkage are drive arms that are removably connected to the actuator. There is a connector clip that connects the drive arms and the linkage together in a removable manner. The connector clip retains the components together during operation, but provides a quick release so that the actuator can be removed and changed without having to disassemble the vanes from the linkage.

Disclosed is a blade adjustment mechanism and an air circulator. The air circulator includes a housing defining an air outlet. The blade adjustment mechanism includes: a fixing bracket fixedly connected with the housing and defining a sliding space; at least two adjustment members, a part of each of the at least two adjustment members is accommodated in the sliding space and slidably connected with the fixing bracket, each of the at least two adjustment members defining a first adjustment slot at an end adjacent to the air outlet; at least two first wind deflectors, a part of one of the at least two first wind deflectors being configured to extend into the air outlet and being rotationally connected with the fixing bracket, a part of one of the at least two first wind deflectors facing away from the air outlet being movably accommodated in the first adjustment slot.
