Abstract

[Problème] La présente invention concerne une unité extérieure équipée d'une poignée intégralement moulée, facile à tenir ayant une grande précision dimensionnelle, un dispositif de climatisation et un procédé de fabrication d'une poignée d'unité extérieure. [Solution] L'unité extérieure selon la présente invention est pourvue d'un boîtier et d'une poignée disposée sur une partie d'angle du boîtier et ayant une forme de L en vue en plan. La poignée comprend une partie de cadre de fixation fixée au boîtier, et une partie de préhension qui est intégalement formée avec la partie de cadre de fixation et formée intérieurement avec une partie d'espace. La partie d'espace est configurée de telle sorte que le volume augmente depuis une direction de grand côté de la poignée vers une direction de petit côté de celle-ci.
