WIPO Patent Application WO/2023/142932

A1

An air channel assembly and an air conditioning device (100) having same. The air channel assembly comprises an upstream air channel part (1) and a cross-flow air channel part (2); the air channel assembly is provided with an air supplementing path (3); an air inlet (31) of the air supplementing path (3) is located in an air outlet section (212), and is in communication with the area of a cross-flow air channel (23) located downstream of a fan mounting cavity (231); an air outlet (32) of the air supplementing path (3) is provided between a volute tongue section (211) and the upstream air channel part (1), is open towards the outside of the cross-flow air channel (23), and is in communication with an upstream air channel (11). The air channel assembly can effectively improve the air inlet efficiency of the cross-flow air channel (23), improve the air flow performance in the cross-flow air channel (23), improve the pressure resistance of the cross-flow air channel (23), and improve the air volume of the cross-flow air channel (23).
