Document Type and Number:
WIPO Patent Application WO/2023/077775
Kind Code:
A1
Abstract:
An air duct assembly and an air conditioner. The air duct assembly comprises: a first side housing (1) and a second side housing (2), side surfaces of which are arranged opposite and spaced apart from each other; and at least one air guide plate (3). The first side housing (1) and the second side housing (2) define an air duct (4) therebetween; two ends of the air duct (4) in the widthwise direction of the first side housing (1) respectively have an air inlet (42) and an air outlet (41); an inner wall surface of the first side housing (1) comprises a main wall surface and a flow guide surface (111) close to the air outlet (41); the flow guide surface (111) is bent relative to the main wall surface in a direction away from the second side housing (2); the air guide plate (3) is arranged in the air duct (4) at a position close to the air outlet (41); and the air guide plate (3) can rotate around a central axis thereof, and the central axis of the air guide plate (3) is parallel to a height direction of the first side housing (1). In the air duct assembly and the air conditioner, the flow guide surface is conducive to reduction in air loss and increase in air volume, such that an air supply mode of large angle, long distance and large air volume is achieved, thus the problems of a small air supply angle, a small air volume and a short air supply distance caused by a small air outlet area of existing air conditioners are solved.
