AI Technical Summary

Technical Problem

The indoor unit of the existing air conditioner has poor air output when switching between cooling and heating modes, and the need for multiple motors to drive multiple airflow control boards results in high cost and large space occupation.

Method used

The system employs first and second airflow control boards, which are connected to the transmission assembly via a drive component to adjust the area of ​​the main and auxiliary air vents. These vents can be switched to return air vents or air outlets in hot and cold modes, respectively, thus reducing the number of drive components.

Benefits of technology

It improves the ventilation effect of the air conditioner, reduces manufacturing costs and the volume space occupied by the drive components, and enables flexible adjustment of the ventilation opening area.

Abstract

The application provides an air flow path switching assembly of an air conditioner and an indoor unit with the same. In the air flow path switching assembly, a driving part drives a first supporting member to drive a first air flow control plate to rotate relative to a main air vent, and the driving part drives a second supporting member to drive a second air flow control plate to rotate relative to an auxiliary air vent through a first transmission assembly, so as to switch among a first state that the first air flow control plate closes the main air vent and the second air flow control plate closes the auxiliary air vent, a second state that the first air flow control plate exposes the main air vent and the second air flow control plate exposes the auxiliary air vent, or a third state that the first air flow control plate exposes the main air vent and the second air flow control plate closes the auxiliary air vent. In the scheme, the opening area of the first air vent can be adjusted through the first air flow control plate and the second air flow control plate, and the area of the first air vent can be adjusted when the air conditioner switches between the cooling mode and the heating mode, thereby improving the ventilation effect.
