Air conditioners and air conditioners

Abstract

The invention belongs to the field of air conditioners, and in particular relates to an air conditioner inner unit and an air conditioner. The present invention aims to solve the problem that in the existing air conditioner inner unit, the diameter of the indexing circle of the intermediate gear is often set relatively large, thereby occupying the space in the casing, resulting in a larger volume of the air conditioner inner unit. The air conditioner inner unit and the air conditioner in the embodiments of the present invention include a casing, a panel, a rotating device, a driving gear, an intermediate gear, an auxiliary reduction gear, and a rack. The above-mentioned rotating device is connected with the driving gear, and the intermediate gear meshes with the driving gear. The diameter of the indexing circle of the intermediate gear is larger than that of the driving gear; the diameter of the indexing circle of the auxiliary reduction gear is smaller than the diameter of the indexing circle of the intermediate gear. The reduction gear meshes with the rack. Through the above settings, two decelerations are performed. Compared with deceleration by increasing the diameter of the index circle of the intermediate gear, the diameter of the index circle of the intermediate gear can be reduced, thereby reducing the space occupied by the intermediate gear and reducing the air conditioner internal unit. volume of.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to an air conditioner inner unit and an air conditioner. Background technique [0002] The air conditioner includes an indoor unit located indoors and an outdoor unit located outdoors, and the external unit is used to deliver refrigerant to the indoor unit.

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the existing air-conditioning internal unit, due to the high speed of the motor, in order to avoid the excessive speed of panel movement, the diameter of the index circle of the intermediate gear is often set to be relatively large, thereby occupying The space in the housing leads to the problem of a large volume of the air conditioner inner unit. An embodiment of the present invention provides an air conditioner inner unit, including: a housing, a panel, a rotating device, a driving gear, an intermediate gear, an auxiliary reduction gear, and a rack; The rotating device is arranged on the housing, and the rotating device is connected to the drive gear in transmission; the intermediate gear is rotatably connected to the housing, and the intermediate gear meshes with the driving gear , the pitch circle diameter of the intermediate gear is larger than the pitch circle diameter of the driving gear; the axis of the auxiliary reduction gear is arranged in line with the axis of the intermediate gear and connected to one end of the intermediate gear, so The index circle diameter of the auxiliary reduction gear is smaller than the index circle diameter of the intermediate gear; the auxiliary reduction gear meshes with the rack; the rack is slidingly connected to the housing, and the housing There is also an installation port on the top, the panel covers the installation port, and the rack is connected to the panel
