いた。However, in view of processing technology and safety, the conventional air guider has a limited gap 13 between it and the centrifugal impeller, as shown in FIG. However, judging from the aspects of air flow characteristics, fan efficiency, and noise level, it has been known for some time that performance will improve if the optimal gap is smaller than the above limit. this is,
This is because within the current limit size of 13, backflow occurs at the contact portion between the air guider and the blown air. Therefore,
If the above-mentioned limitation on the gap 13 between the conventional impeller blade suction end face and the peripheral tip of the air guider intake hole is adopted, the air volume characteristics and noise characteristics of the air conditioner blower will deteriorate, and the fan efficiency will decrease. That was a big factor.
