Abstract

The invention provides an air duct rotating mechanism, an indoor unit and an air conditioner. The air duct rotating mechanism comprises: a fan, wherein the fan comprises fan blades and a fan shell, and the fan blades and the fan shell are rotatably arranged to supply air and change the air outlet angle; and two bearing assemblies arranged on the two opposite sides of the fan in the axial direction of the fan and fixed to a machine body of an indoor unit of the air conditioner, wherein each bearing assembly comprises a shell bearing used for being connected with a fan shell so as to support the fan shell. Each shell bearing comprises a sleeving part and a stopping part, the sleeving part is used for being connected with the shell rotating shaft of the fan shell in a sleeving mode, and the stopping part is arranged at the end, away from the fan shell, of the sleeving part and used for stopping axial movement of the fan shell, so that the problem that in the prior art, axial movement exists in a fan shell of an air conditioner is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air duct rotation mechanism, an indoor unit and an air conditioner. Background technique [0002] When the existing wall-mounted air conditioners are in operation, the upper and lower air outlet directions and angles of the air conditioner are adjusted by swinging the air deflector up and down, but there are some problems in the air deflectors of the wall-mounted air conditioners: The wind angle is limited so that the comfort is deteriorated, and the range of the upper and lower sweeping angles of the wind deflector is small so that it cannot meet the user's requirements. [0003] In order to solve the above problems, an air conditioner indoor unit is proposed, the fan housing of which can be rotated to realize large-angle rotation and air supply. [0004] However, when designing an air conditioner in which the fan housing can rotate to supply air, the axial movement...
