In some alternative embodiments, the centrifugal fan 20 comprises: the volute 21 is provided with an air suction opening 211 and an air exhaust opening 212, and the air exhaust opening 212 is communicated with the air outlet 102; the impeller 22 is arranged in the volute 21; the connecting plate 23 is embedded in the inner ring of the impeller 22 in a manner of being perpendicular to the axis of the impeller 22, and the edge of the connecting plate 23 is fixedly connected with the impeller 22; the connecting plate 23 can rotate to drive the impeller 22 to rotate, the motor 24 is in driving connection with the connecting plate 23, and the motor 24 is used for driving the connecting plate 23 to rotate.
Optionally, the axial dimension of impeller 22 is smaller than the radial dimension of impeller 22. In this way, the impeller 22 is designed to be flat, so that the axial size of the centrifugal fan can be further reduced, and the requirement on the height size of the cabinet-mounted air conditioner indoor unit is further reduced.
For example, as shown in fig. 3, the centrifugal fan 20 is a double-inlet centrifugal fan 20, the upper and lower surfaces of the volute 21 of the centrifugal fan 20 are respectively provided with an air inlet 211, and the air outlet 212 of the volute 21 is communicated with the air outlet 102 of the housing 10 to form an air outlet channel, and since the centrifugal fan 20 is disposed close to the air outlet 102, the length of the air outlet channel can be effectively shortened, thereby reducing the wind loss during the air outlet process of the centrifugal fan 20 and ensuring a better air outlet effect of the air conditioner.
The connecting plate 23 is embedded in an inner ring of the impeller 22 in a manner perpendicular to an axis of the impeller 22, where the inner ring means that the connecting plate 23 is connected to any one horizontal plane except two side surfaces of the impeller 22, that is, the connecting plate 23 is spaced from both side surfaces of the impeller 22.
