本発明は、空気調和機に係り、特に暖房における除霜運
転時の除霜効果を高め、暖房能力向上に好適な空気調和
機に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an air conditioner, and particularly relates to an air conditioner suitable for improving the heating capacity by increasing the defrosting effect during defrosting operation in heating. be.
従来の空気調和機は、室外側熱交換器を室外側送風機の
吸込側に設置し、除霜運転時は室外側送風機を停止し、
室外側熱交換器の除霜を行い、除−霜終了後は室外側送
風機を運転し、暖房運転を再開するものである。In conventional air conditioners, the outdoor heat exchanger is installed on the suction side of the outdoor fan, and the outdoor fan is stopped during defrosting operation.
The outdoor heat exchanger is defrosted, and after the defrosting is completed, the outdoor fan is operated to resume heating operation.
上記従来技術は、除霜運転終了後、・室外側熱交換器の
フィン間に水滴が残存しており、暖房運転を再開するこ

熱量が減少し、暖房能力を低下してしまう可能性があっ
た。In the above conventional technology, after the defrosting operation ends, water droplets remain between the fins of the outdoor heat exchanger, and when the heating operation is restarted, these water droplets refreeze and are absorbed from the outdoor heat exchanger. There was a possibility that the amount of heat would decrease and the heating capacity would decrease.
本発明の目的は、室外側送風機を除霜終了時に一定時間

運転時の水滴の再凍結を無（し、暖房能力の向上を図っ
た空気調和機を提供することにある。The purpose of the present invention is to rotate the outdoor air blower in reverse for a certain period of time after defrosting, remove water droplets remaining between the fins, eliminate the refreezing of water droplets when restarting heating, and improve heating capacity. Our goal is to provide air conditioners with a high level of quality.

きとばすものである。In this embodiment, during normal cooling and regret operation, the wind flows as shown by the arrow shown by the solid line, and the outdoor heat exchanger 2 is installed on the suction side of the blower impeller 3 to reduce noise. . During defrosting operation in heating, the blower electric motor 4 is stopped during the defrosting operation to effectively defrost the air, and after the defrosting is completed, the blower electric motor 4 is rotated in reverse for a certain period of time, as shown by the arrow indicated by the broken line. This is to change the flow of the air and blow away the water droplets remaining in the outdoor heat exchanger 2.
