AI Technical Summary
Technical Problem
Existing air conditioners use cross-flow fans, resulting in a large vertical height of the unit, which takes up a lot of space and is inconvenient to move and place.
Method used
Multiple air duct components are arranged sequentially and spaced apart in the vertical direction. Each air duct component includes a centrifugal impeller, which increases the air volume and reduces the overall height of the unit in the vertical direction. Multiple centrifugal impellers arranged vertically replace the cross-flow impeller.
Benefits of technology
While maintaining the same maximum airflow, reducing the vertical height of the air conditioner saves space, makes it easier to move and place, and improves the performance of the air conditioner.

Abstract
The utility model discloses an air conditioner, include: casing, heat exchanger subassembly and air duct subassembly. The rear side of casing forms the air inlet, and the front side of casing forms the air outlet, air duct subassembly is located in the casing and is located between the air outlet and heat exchanger subassembly, and air duct subassembly includes a plurality of air duct parts that are sequentially spaced along the up-down direction, and each air duct part includes an air duct volute and a centrifugal fan wheel arranged in the air duct volute, at least one side of the air duct volute in the up-down direction forms the airflow inlet, and the front side of the air duct volute forms the airflow outlet, and the airflow outlet faces the air outlet and communicates with the air outlet. According to the air conditioner of the utility model embodiment, the air conditioner can have a large air volume, and the performance of the air conditioner is improved. Moreover, compared with the use of a cross-flow fan wheel, the use of a plurality of centrifugal fan wheels arranged along the up-down direction can reduce the height dimension of the whole machine in the up-down direction under the condition that the maximum air volume is the same, save space, and facilitate the carrying or placing of the air conditioner.
