Title
(EN) BLOWER DEVICE, AND OUTDOOR UNIT FOR AIR CONDITIONER
(FR) DISPOSITIF SOUFFLANT ET UNITÉ D'EXTÉRIEUR POUR CLIMATISEUR
(JA) 送風装置及び空気調和装置用室外機
Abstract
(EN) This blower device is provided with: a propeller fan having a shaft section which is provided on a rotation axis, and having blades which are provided around the shaft section; and a fan guard provided downwind of the propeller fan and having ribs which define a plurality of openings through which air is allowed to flow. When viewed in a direction parallel to the rotation axis, the fan guard has a first region which is disposed overlapping the shaft section, and a second region which is located on the outer peripheral side with respect to the shaft section and the inner peripheral side with respect to the path of rotation of the blades. If the dimension of the ribs in the direction parallel to the rotation axis is defined as the height of the ribs, the height of the ribs in the first region is less than the height of the ribs in the second region.
(FR) L'invention concerne un dispositif soufflant comprenant : un ventilateur hélicoïdal ayant une section d'arbre qui est disposée sur un axe de rotation, et ayant des pales qui sont disposées autour de la section d'arbre ; et un protège-ventilateur disposé sous le vent du ventilateur hélicoïdal et ayant des nervures qui définissent une pluralité d'ouvertures à travers lesquelles l'air peut s'écouler. Lorsqu'il est observé dans une direction parallèle à l'axe de rotation, le protège-ventilateur comprend une première région qui est disposée en chevauchement de la section d'arbre, et une deuxième région qui est située sur le côté périphérique extérieur par rapport à la section d'arbre et sur le côté périphérique intérieur par rapport au trajet de rotation des pales. Si la dimension des nervures dans la direction parallèle à l'axe de rotation est définie comme la hauteur des nervures, la hauteur des nervures dans la première région est inférieure à la hauteur des nervures dans la deuxième région.
(JA) 送風装置は、回転軸上に設けられた軸部、及び軸部の周囲に設けられた翼を有するプロペラファンと、プロペラファンの風下側に設けられ、空気を通過させる複数の開口を画定するリブを有するファンガードと、を備え、回転軸と平行に見たとき、ファンガードは、軸部と重なって配置された第1領域と、軸部よりも外周側であって翼の回転軌跡よりも内周側に配置された第2領域と、を有しており、回転軸と平行な方向におけるリブの寸法をリブの高さと定義した場合、第1領域でのリブの高さは、第2領域でのリブの高さよりも低い。
