  • the rear flat section (cd section) close to the fan 30 is a straight section, which is beneficial to keep the wind from the fan stable.
  • the middle arc section (bc section) can expand the wind angle, change the wind direction, and increase the wind volume when the flow resistance is the least.
  • the outermost section of the upper wall 41 of the air duct is the front flat section (section ab), which can be horizontal or have a certain upward inclination angle, which can make the air flow out of the wind stable and have better flow directionality.
  • This design for the shape of the upper wall 41 of the air duct makes the air volume and air flow stability better when the air supply air is blown upward.
  • the ratio of the length L ab is preferably provided rear plate section (cd segment) length L cd front plate section (ab section) is between 0.3 to 0.6, the above effect can be enhanced.

Abstract

Unité intérieure d'un climatiseur, comprenant : un boîtier (10), une première plaque de guidage d'air (60) et une seconde plaque de guidage d'air (50). Le boîtier (10) est pourvu d'une sortie d'air (12) orientée vers l'avant et vers le bas. La première plaque de guidage d'air (60) et la seconde plaque de guidage d'air (50) sont montées de manière rotative respectivement sur le côté avant et le côté inférieur de la sortie d'air (12), de façon à ouvrir et fermer la sortie d'air (12) en coopération. La seconde plaque de guidage d'air (50) est configurée pour : être rotative par rapport à un état de guidage d'air vers l'avant dans lequel la seconde plaque de guidage d'air est située sur le côté inférieur de la sortie d'air (12) et une surface de guidage d'air (511) de celle-ci est tournée vers le haut de façon à guider un flux d'air d'alimentation en air vers l'avant, vers l'avant et vers le haut, ou vers l'avant et vers le bas ; et être rotative par rapport à un état de guidage d'air vers le bas dans lequel la seconde plaque de guidage d'air est située sur le côté arrière de la sortie d'air (12) et la surface de guidage d'air (511) de celle-ci est tournée vers l'avant de façon à guider le flux d'air d'alimentation en air vers le bas. L'unité intérieure d'un climatiseur peut réaliser un soufflage vers le haut d'air froid et le soufflage vers le bas d'air chaud.
