Drive assembly, air discharge structure, and air conditioner

By designing the first and second drive components in the drive box within the air conditioner to drive the door and air guide grille to rotate coaxially, and by setting connecting plates at intervals in the radial direction, the problem of rotational interference between the door and air guide grille is solved, thus achieving the stability and reliability of the drive assembly.

AI Technical Summary

Technical Problem

In existing air conditioners, multiple rotating parts, such as door opening and closing mechanisms and air deflectors, are prone to interference with each other, leading to damage to parts and affecting stability and reliability.

Method used

Design a drive assembly that drives the door and air guide grille to rotate coaxially via a first and second drive component inside the drive box, and is radially spaced with the output shaft of the drive component via a connecting plate to avoid rotational interference.

Benefits of technology

It effectively avoids interference between the opening and closing of the door and the rotation of the air guide grille, ensuring the stability and reliability of the drive components, reducing the risk of component damage, and extending service life.

Abstract

A drive assembly, an air discharge structure, and an air conditioner. The drive assembly (400) comprises: a drive box (60), the drive box (60) comprising an upper cover (64) and a box body (61), the upper cover (64) covering the box body (61) and being connected to the box body (61), the upper cover (64) having a first drive hole (644) and a clearance hole (643); a first drive member (410), at least part of the first drive member (410) being arranged inside of the box body (61), an output shaft of the first drive member (410) being rotatably disposed in the first drive hole (644) for driving a switch door (300) to rotate; and a second drive member (420), at least part of the second drive member (420) being arranged inside of the box body (61), the second drive member (420) comprising a connecting plate (301), the connecting plate (301) being rotatably disposed in the clearance hole (643) and synchronously rotating with an output shaft of the second drive member (420) to drive an air deflection grille (200) to rotate, and the connecting plate (301) and the output shaft of the first drive member (410) being spaced apart in a radial direction.
