Description

Air conditioner Technical Field The invention relates to the technical field of refrigeration, in particular to an air conditioner. Background A general air conditioner (air conditioning indoor unit) includes at least two air ports, one for only air outlet and the other for only return air, and air flow is caused to flow between the two air ports by rotation of a fan in the air conditioning indoor unit. Along with the pursuit of people to the air conditioning travelling comfort constantly improves, the air conditioner indoor unit needs to change the air-out direction according to operating mode, but because the fan blade of fan has the directionality requirement, drives fan blade pivoted motor reversal back, and the air current switching-over is difficult, makes the air-out direction of indoor unit unable adjustment, and the air-out direction is single, is difficult to satisfy user's diversified demand. In some schemes, the mixed flow fans are rotated 180 degrees in the air conditioner inner unit by arranging a plurality of mixed flow fans, so that the reverse air outlet is realized. The driving device for realizing the rotation of the fan is usually used, and is a motor matched with a rotation mechanism to drive the fan to rotate, so that the motor of the fan is supplied with power during rotation, and meanwhile, the motor wire is ensured not to be twisted.
