Abstract

The present invention provides an air conditioner, comprising: a casing with an air inlet and an air outlet; a centrifugal fan rotatably arranged in the casing, the centrifugal fan includes a disk and fan blades arranged on the disk; a heat exchanger , the heat exchanger is arranged in the casing; the sliding support part is arranged in the casing to support the centrifugal fan. The technical solution of the application effectively solves the problem that the large-diameter centrifugal fan in the prior art cannot operate stably.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to an air conditioner. Background technique [0002] At present, the diameter of the fan blades of the centrifugal fan used in the indoor unit of the air conditioner is relatively small. During the rotation of the centrifugal fan, the centrifugal fan shakes little, and the centrifugal fan will not hit other parts. However, the centrifugal fan with small-diameter fan blades will affect the air volume and performance of the air conditioner. [0003] With the improvement of people's requirements for air-conditioning performance, centrifugal fans with smaller diameter blades can no longer meet people's needs, so centrifugal fans with larger diameters need to be used. Such as figure 1 with figure 2 As shown, for the indoor unit of the centrifugal fan 20' of the large-diameter fan blade, the centrifugal fan 20' is driven and fixed by a motor in the prior art. Such as figure 2 As shown...
