  • volute 410 and the volute tongue 420 are preferably coupled to the lateral ends of the frame 610 to direct the wind directly to the pendulum 620 mounted on the frame 610, the flow of the wind being as shown by the arrow in Fig. 7. Show.
  • each air guiding device 600 further includes driving devices, each driving device for driving one pendulum group, each of which includes a motor 640, a main rocker 630, a connecting rod 660, and more.
  • Rocker 630 The motor 640 is mounted to the frame 610.
  • One end of the main rocker 630 is fixedly coupled to the rotating shaft of the motor to be oscillated by the driving of the motor, and the other end of the main rocker 630 is hinged to the connecting rod 660.
  • the plurality of rockers 630 are matched with the plurality of pendulum blades 620 of the pendulum group.
  • each rocker 630 is fixedly coupled to the pivot shaft of the pendulum blade 620, and the other end is hinged to the link 660.
  • the motor 640 can be controlled to rotate, so that the main rocker 630 swings, the main rocker 630 drives the link 660 to translate, and the link 660 drives the plurality of rockers 630 to swing synchronously.
  • the rocker 630 drives the plurality of pendulum blades 620 to pivot synchronously.
  • the motor 640 is preferably a stepper motor with better controllability during the rotation process.
  • the body detection device 800 further includes a hemispherical baffle 850 with an opening facing forward.
  • the hemispherical shielding plate 850 is disposed on the rear side of the spherical shell 810 at a distance from the spherical shell 810 and is fixed to the mounting case 840.
  • the human body detecting device 800 is configured to cause the temperature-cooling sensor 820 to detect only the indoor temperature when the spherical shell 810 is rotated until the hemispherical shielding plate 850 completely blocks the detecting light path of the temperature-sensing sensor 820.
  • the probe of the temperature-sensing sensor 820 when the probe of the temperature-sensing sensor 820 is rotated to the rear side, it cannot receive the infrared signal emitted by the human body in the indoor space, so that it detects only the indoor temperature and avoids erroneous detection.

Abstract

Unité de climatisation intérieure verticale, comprenant : une coque (100), une pluralité de sorties d'air (112) étant disposées verticalement sur un panneau avant (110) de la coque (100), et une entrée d'air (122) disposée sur le côté arrière de la coque (100) ; un échangeur de chaleur (200) disposé dans la coque (100) ; un premier ventilateur à flux transversal (310) et un second ventilateur à flux transversal (320) qui sont disposés verticalement dans la coque (100), les axes des ventilateurs à flux transversal s'étendant verticalement et étant agencés de manière colinéaire, et les ventilateurs à flux transversal étant respectivement configurés pour entraîner de l'air à entrer dans la coque (100) à travers l'entrée d'air (122), et pour souffler l'air vers l'extérieur à partir des sorties d'air correspondantes (112) après l'échange de chaleur de l'échangeur de chaleur (200) ; un moyen de détection de corps humain (800) configuré pour détecter des informations de corps humain d'intérieur, les informations de corps humain comprenant le nombre de personnes, une température de corps humain et une position de corps humain ; et une carte de commande maître configurée pour commander, en fonction des informations de corps humain, le premier ventilateur à flux transversal (310) et le second ventilateur à flux transversal (320) pour être allumés simultanément ou alternativement, et pour commander la vitesse du vent du premier ventilateur à flux transversal (310) et du second ventilateur à flux transversal (320) et la direction de sortie du vent des sorties d'air.
