  • a convex curved surface faces the inside of the air duct 20 , and the airflow is smoothly distributed to the two horizontal tips of the air guide 50 , that is, the two air outlet gaps 201 , by using the convex curved surface.
  • Another convex curved surface faces the first air supply port 11, and the airflow can guide the airflow at the two air outlet gaps 201 to flow along the surface of the convex curved surface toward its center under the effect of the Coanda effect, and contribute to the two Aggregation of air streams.
  • each deflector 50 is translatably mounted on the casing 10 to approach or move away from the first air outlet 11 in translation, so as to adjust the air volume of the air outlet gap 201 .
  • Adjusting the air volume of the air outlet gap 201 includes adjusting the air outlet gap 201 to zero.
  • the air guide 50 is located behind the first air supply port 11. Since the flow cross section of the air duct 20 at the first air supply port 11 is tapered, when the air guide 50 is moved backward, the air guide 50 and the wind The distance between the inner walls of the channel 20 becomes larger, so that the air outlet gap 201 becomes larger.
  • the deflector 50 When the deflector 50 is moved forward, the distance between the deflector 50 and the inner wall of the air duct 20 becomes smaller, so that the air outlet gap 201 becomes smaller.
  • the air outlet gap 201 disappears, and the first air outlet 11 is closed.
  • the wind force can be increased by increasing the air outlet gap 201 to achieve rapid cooling/heating; the wind force can be reduced by reducing the air outlet gap 201 to simulate natural wind and make the air flow more comfortable.
  • the air conditioner operates in cooling mode, and when there are elderly people, children, pregnant women and other people who cannot withstand forced cooling in the room, you can choose to reduce the wind power to operate.
  • Fig. 7 is a C-C sectional enlarged view of the vertical air conditioner indoor unit shown in Fig. 2 .
  • the deflector 50 is installed on the casing 10 through a rack and pinion mechanism.
  • the rack and pinion structure includes a motor 71 , a gear 72 and a rack 73 .
  • the motor 71 drives the gear 72 to rotate.
  • the gear 72 meshes with the rack 73
  • the rack 73 is fixed on the bottom of the deflector 50 .
  • each deflector 50 may be a hollow structure. In this way, the weight of the flow guiding member 50 is lighter, which facilitates its translation.

Abstract

La présente invention concerne une unité intérieure de climatiseur vertical comprenant : un carter, qui s'étend sous la forme d'une colonne verticale, au moins un conduit d'air étant délimité dans le carter, et le carter étant pourvu d'au moins un premier orifice d'alimentation en air en forme de bande verticale et d'au moins une partie d'alimentation en air expansé; et au moins un élément de guidage d'écoulement, chaque élément de guidage d'écoulement s'étendant verticalement sous la forme d'une colonne et étant agencé au niveau de l'un des premiers orifices d'alimentation en air, de façon à délimiter un espace de sortie d'air avec une paroi interne du conduit d'air qui est proche du premier orifice d'alimentation en air, de telle sorte qu'un écoulement d'air au niveau du premier orifice d'alimentation en air est soufflé vers un environnement intérieur à travers l'espace de sortie d'air. L'unité intérieure de climatiseur vertical est conçue pour raccorder le conduit d'air au premier orifice d'alimentation en air, ou au premier orifice d'alimentation en air et à la partie d'alimentation en air expansé. Au moyen de l'unité intérieure de climatiseur vertical selon la présente invention, l'expérience d'alimentation en air est meilleure.
