Description

air conditioner indoor unit

This application is based on a Chinese patent application with application number 202111462196.2 and a filing date of December 2, 2021, and claims the priority of this Chinese patent application. The entire content of this Chinese patent application is hereby incorporated by reference into this application.

technical field

The present application relates to the technical field of air conditioning, for example, to an air conditioning indoor unit.

Background technique

At present, after the air conditioner is turned off, the air outlet of the air conditioner is generally covered by an air deflector mechanism. For the air-conditioning cabinet with a higher height, not only the size of the air deflector used is larger, but also its stroke is larger. This not only increases the difficulty of installation, but also reduces the stability of the wind deflector during use.

In order to avoid the use of air deflectors, in the related art, some air conditioners have begun to use flexible switch doors to open or close the air outlets. For example, by arranging a first driving mechanism and a second driving mechanism on the housing of the air conditioner, the first driving mechanism cooperates with the second driving mechanism to make the head type switch door undergo curling deformation to open or close the air outlet. However, when two sets of driving mechanisms are used to drive the flexible switch door at the same time, there may be deviations in the response time between the two sets of drive mechanisms, resulting in poor synchronization, thereby increasing the pulling force on the flexible switch door in two opposite directions at the same time, affecting the flexible switch. The service life of the door.
