Background technology
At present, traditional wall-hanging air conditioner indoor unit is mostly upper air inlet, the airflow circulating mode of lower air-out, and for driving
The device of airflow circulating is mostly axial-flow fan.Air-flow enters the inside of axial-flow fan along the axial direction perpendicular to axial-flow fan,
And the impeller of axial-flow fan is passed twice through, in impeller internal, air-flow is forced to bend so that the pressure loss of air-flow is larger, wind
Measure it is relatively low, complete machine run when noise it is larger.
In order to avoid using axial-flow fan certain driving air-flow tape loop come a series of problems, some wall hangings of the prior art
Axial-flow fan is substituted for centrifugal fan by formula indoor apparatus of air conditioner.Although this wall-hanging air conditioner indoor unit can be to a certain extent
Solve the problems, such as that above-mentioned air quantity is relatively low, air-flow crushing is larger, but effect is not particularly evident, and can not at all solve noise
The problem of larger.Wall hanging has been had a strong impact on as the defects of noise is big, the small this user of air quantity can be experienced by direct feel
The overall performance of formula indoor apparatus of air conditioner, and greatly limit the use range of wall-hanging air conditioner indoor unit.
The content of the invention
The purpose of the present invention is intended to overcome at least one defect of the prior art, there is provided a kind of air quantity is larger and noise compared with
Small indoor apparatus of air conditioner.
