  • the lead wire 60 is prevented from being exposed to the outside, and the lead wire 60 is reliably prevented from touching.
  • the edge 142B of the lid 142 and the lower end 51A of the standing wall 51 is shorter than the thickness D of the lead wire 60, the edge 142B of the lid 142 and the standing wall It is possible to prevent the lead wire 60 from being pulled out from the gap between the lower end 51 ⁇ / b> A of the 51.
  • the standing wall 51 has the curved portion 51B that widens the gap width of the wiring portion 146 more than the other positions at a position facing the lead wire drawing hole 145A of the side plate 145 of the electrical box main body 141. Therefore, when the connection work is performed, the lead wire 60 can be gently bent, and an excessive load can be prevented from being applied to the lead wire 60.
  • the lid 142 of the electrical box 140 is described as a configuration in which the edge 142B of the lid 142 is arranged so as to partially cover the wiring portion 146 in the width direction.
  • the body 142 may entirely cover the wiring portion 146 in the width direction.

Abstract

L'invention porte sur un climatiseur incorporé dans un plafond, lequel climatiseur a une configuration simple et est apte à réduire un bruit de soufflante pendant le fonctionnement. A l'intérieur d'un boîtier (1) sont disposés une soufflante (9), un échangeur de chaleur sensiblement pentagonal (11) agencé de façon à entourer la soufflante (9), et une plaque de rectification (41), dont une extrémité (41A) est fixée à un côté aspiration de parties linéaires (11A, 11B, 11C, 11E) de l'échangeur de chaleur (11), et dont l'autre extrémité (41B) s'étend vers la soufflante (9). La plaque de rectification (41) comporte une partie irrégulière dans laquelle une pluralité de creux et de saillies sont formés de façon continue dans la direction longitudinale de l'autre extrémité (41B).
