  • the heat source unit (not shown) of the dehumidifying unit 303 in which the dehumidifying capacity is stopped is operated to perform heating.
  • the humidifying operation mode the heat source unit of the dehumidifying unit 303 and the humidifying unit 304 are operated simultaneously.
  • the air flow formed by the fan 302 passes through the heat exchange unit of the dehumidifying unit 303 whose dehumidifying capacity is stopped and flows to the humidifying unit 304. And since this air is heated by the heat exchange part of the dehumidification unit 303 and enters the humidification unit 304 in a state where the relative humidity is lowered, a lot of moisture is humidified. Moreover, since the air which passes the dehumidification unit 303 is heated by the heat exchange part, the temperature rise width of air is low and it is suitable for small-scale heating.
  • the humidifying capacity of the humidifying unit 304 is stopped, and moisture in the air is adsorbed by the dehumidifying unit 303.
  • the control unit 300 controls the geared motor 343, and the humidifying filter 340 rotated by the geared motor 343 is supplied with water from the watering device 360, whereby the humidifying filter. It is possible to prevent water splashing due to the humidifying filter 340 repelling water at the time of starting the humidifying operation in which the humidifying preparation operation in which water is immersed in 340 is performed.
  • the air conditioner of the second embodiment has the same effect as the humidifier of the first embodiment by applying or controlling the same configuration as the humidifier of the first embodiment.
  • the geared motor 343 also serves as a driving device that rotates the humidifying filter 340 that is a humidifying member and a driving unit of the watering device 360 that is a water supply device.

Abstract

L’invention concerne un appareil humidificateur comprenant : un ventilateur (20) disposé dans un boîtier (1) ; un filtre humidifiant (40) afin d’humidifier un flux d’air produit par le ventilateur (20) ; un plateau à eau (90) disposé sous le filtre humidifiant (40) ; un éclabousseur à eau (60) comportant un cadre rotatif supportant le filtre humidifiant (40) et supporté en rotation par le boîtier (1), et une unité seau (61) montée sur le cadre rotatif afin de puiser de l’eau dans le plateau à eau (90) et de la projeter sur le filtre humidifiant (40) ; un moteur à engrenages (74) pour faire tourner le cadre rotatif de l’éclabousseur à eau (60) ; et une unité de commande (200) pour commander le ventilateur (20) et le moteur à engrenages (74). L’unité de commande (200) commande le moteur à engrenages (74) avant l’opération d’humidification, et commande la rotation du cadre rotatif de l’éclabousseur à eau (60), réalisant ainsi une opération de préparation à l’humidification dans laquelle le filtre humidifiant (40) est imprégné d’eau.
