Since the heat exchanger 40 has completely blocked the inlets of the two main air passages 20, 30, the heat exchange air flow completely enters the two main air passages 20, 30, avoiding waste of air volume.
  • Fig. 7 is a schematic diagram of the control method of the air conditioner indoor unit of the present invention.
  • the present invention also provides a control method for an air conditioner indoor unit, which is used to control the air conditioner indoor unit in any of the above embodiments, which includes the following steps:
  • Step S702 Detect the position of the human body, and determine the main air outlets 11, 13 that are closer to the human body.
  • two main air supply ports 11, 13 are arranged laterally.
  • the central symmetry plane Y between the two main air supply ports 11, 13 (the center of the two main air supply ports 11, 13 is symmetrical to Y)
  • the interface Y divides the indoor space into two areas, S1 and S2.
  • the senor can be used to detect the position of the human body.
  • Step S704 Control the movement of the air path switching component 50 to connect the bypass openings 21, 31 of the air ducts corresponding to the main air outlets 11, 13 closer to the human body and the air flow path between the middle air outlet 12, and close the other bypass The airflow path between the openings 21 and 31 and the middle air outlet 12 .
  • the indoor unit of the air conditioner selects the main air ducts 20, 30 that need to be diverted according to the position of the human body, so that the main air ducts 20, 30 corresponding to the main air outlets 11, 13 that are closer to the human body
  • the regulated airflow is "split" to the middle air supply port 12 to blow out, so that the total air outlet cross section of the main air ducts 20, 30 is larger, the impact force of the airflow is smaller, and the wind feeling of the human body is more comfortable.

Abstract

Unité intérieure de climatiseur et procédé de commande associé, l'unité intérieure de climatiseur comprenant un boîtier de machine et un composant de commutation de trajet d'air ; le boîtier de machine définit deux conduits d'air principaux et un conduit d'air intermédiaire situé entre les deux conduits d'air principaux ; chaque conduit d'air principal est doté d'une ouverture d'alimentation en air principale, et le conduit d'air intermédiaire est doté d'une ouverture d'alimentation en air intermédiaire située entre les deux ouvertures d'alimentation en air principales ; chaque conduit d'air principal est doté d'une ouverture de dérivation utilisée pour régler et injecter un flux d'air dans le conduit d'air intermédiaire ; le composant de commutation de trajet d'air est agencé de façon mobile dans le conduit d'air intermédiaire et est configuré pour fermer de manière contrôlable des trajets de flux d'air entre les deux ouvertures de dérivation et l'ouverture d'alimentation en air intermédiaire, ou ouvrir sélectivement un trajet de flux d'air entre une ou les deux ouvertures de dérivation et l'ouverture d'alimentation en air intermédiaire. L'unité intérieure de climatiseur de la présente invention présente une plus grande variété de modes de réglage d'alimentation en air, et une meilleure expérience utilisateur est fournie.
