Description

図１８(d)，(e)は、本空気循環装置１１を示すものであるが、ノズル２０の吹出し口部分Ｂは、ベンチュリー１３の入口部１３ａとの間から周囲空気が誘引されるため、該誘引空気により、ノズル２０の吹出し口部分に風速が０［ｍ／ｓ］となるところはなく、従ってノズル２０の周縁に霜等が付着して生長することはない。また、ベンチュリー１３の出口１３ｂは、吹出し気流の広がり角に適合した先端形状からなるため、該出口部分Ｃに発生する渦流は極めて少なく、霜等が付着して生長することはない。 18 (d) and 18 (e) show the main air circulation device 11, but the outlet portion B of the nozzle 20 attracts ambient air from the inlet portion 13a of the venturi 13. by the attraction air, rather than where the wind speed is 0 [m / s] in the air outlet portion of the nozzle 20, therefore does not frost or the like to grow attached to the periphery of the nozzle 20. Further, since the outlet 13b of the Venturi 13 has a tip shape that matches the spread angle of the blown airflow, the eddy current generated at the outlet portion C is extremely small, and frost or the like does not adhere to the outlet portion C to grow.
