Abstract

The invention discloses a centrifugal wind wheel and an air conditioner indoor unit. The centrifugal wind wheel comprises a blade seat, a first air inducing ring and a plurality of fan blades connecting the blade seat with the first air inducing ring. The centrifugal wind wheel further comprises a second air inducing ring, the second air inducing ring is located between the blade seat and the first air inducing ring, and the fan blades penetrate through the second air inducing ring to be connected with the second air inducing ring. The second air inducing ring is provided with a first end opening and a second end opening, wherein the first end opening and the second end opening are formed oppositely. The first end opening of the second air inducing ring is close to the blade seat, and thediameter of the second air inducing ring is gradually reduced in the direction from the first end opening to the second end opening. By means of the centrifugal wind wheel and the air conditioner indoor unit, the air-out uniformity of the centrifugal wind wheel is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a centrifugal wind wheel and an air conditioning indoor unit. Background technique [0002] see figure 1 , the existing centrifugal wind wheel 10' generally includes a blade seat 20', a first wind-inducing ring 30' and a fan blade 40'. Wherein, the fan blade 40' is fixed between the blade seat 20' and the first wind-inducing ring 30', and when the centrifugal wind wheel 10' rotates, the airflow enters from the middle of the first wind-inducing ring 30', and then passes through the fan blade 40' to be discharged from the air passage formed between the blade base 20' and the first wind-inducing ring 30'. [0003] However, most of the air flow formed by the above-mentioned centrifugal wind wheel 10' is discharged from the surface of the blade seat 20', and only a small amount of air flow is discharged along the surface of the first wind-inducing ring 30' (towards the surf...
