  • step S17 the control means Cm stops driving the motor of the compressor 21.
  • step S18 the control means Cm drives the motor 6 so that the shutter 5 rotates to the closed position (step S18), and performs an air cleaning operation (step S19).
  • the right end of the heat exchanger 20 in the Y-axis direction can face the bypass air passage 44, so that the heat exchanger 20 passes through the bypass air passage 44 during dehumidification operation when the bypass air passage 44 is opened.
  • the airflow is ventilated to the right end of the heat exchanger 20 in the Y-axis direction. Therefore, the air can be passed evenly in the left and right directions with respect to the heat exchanger 20, that is, over the entire surface of the heat exchanger 20, and as a result, it is possible to suppress the dehumidification performance of the dehumidifier 1 from deteriorating. can.

Abstract

L'invention concerne un déshumidificateur qui peut réduire au minimum la dégradation des performances de déshumidification du déshumidificateur sans affecter la conception du déshumidificateur au niveau du côté de face arrière.　Le déshumidificateur selon l'invention comprend : un boîtier qui possède un orifice d'entrée et un orifice de sortie ; un moyen de soufflage d'air pour générer un écoulement d'air de l'orifice d'entrée à l'orifice de sortie ; un moyen de purification d'air ; un moyen de déshumidification ayant un échangeur de chaleur pour éliminer l'humidité dans l'écoulement d'air ; un passage d'air principal dans lequel l'air aspiré depuis l'orifice d'entrée s'écoule à travers le moyen de purification d'air pour atteindre l'échangeur de chaleur ; un passage d'air de dérivation dans lequel l'air aspiré depuis l'orifice d'entrée s'écoule vers l'échangeur de chaleur sans passer à travers le moyen de purification d'air ; et un moyen d'ouverture/fermeture qui peut ouvrir et fermer le passage d'air de dérivation. L'orifice d'entrée est formé sur la face arrière du boîtier, de telle sorte que l'orifice d'entrée soit bilatéralement symétrique par rapport à une première ligne centrale qui divise en deux le boîtier dans le sens de la largeur en moitiés gauche et droite et qui s'étend dans la direction avant-arrière. Le moyen de déshumidification comporte une tuyauterie de fluide frigorigène disposée au niveau d'un côté de l'échangeur de chaleur dans la direction gauche-droite. L'échangeur de chaleur est disposé de manière à être bilatéralement symétrique par rapport à une seconde ligne centrale qui s'écarte de l'autre côté dans la direction gauche-droite par rapport à la première ligne centrale. Le passage d'air de dérivation est disposé sur l'autre côté du passage d'air principal dans la direction gauche-droite.
