  • the diffuser 374 is switched to the second state, so that the fan 307 can supply a small amount of air to the adsorbent 304 with a high static pressure.
  • the first state and the second state are obtained by moving the diffuser 374 in a direction D1 in which the rotation shaft 372a extends, which is a direction intersecting the centrifugal direction (the direction of the adsorption exhaust F3). It is possible to easily and reliably switch the state.
  • the diffuser 374 since the diffuser 374 has the sealing material 376 on the joint surface in contact with the fan casing 373, in the second state, the diffuser 374 blows air from the fan rotor 371 in the centrifugal direction.
  • the sealing material 376 can suppress air leakage from the joint surface between the diffuser 374 and the fan casing.
  • a diffuser 374 is employed as a switching member. Therefore, the adsorption exhaust F3, which is the air flow in the centrifugal direction in the first state, can be adjusted to a predetermined air volume and pressure.
  • the present invention is not limited to this.
  • the diffuser 374 is moved in the centrifugal direction (of the adsorbed exhaust F3). It is possible to easily and reliably switch between the first state and the second state in any crossing direction as long as it moves in the direction crossing the direction.
  • the present invention can be used for a humidifying unit that heats an adsorbent with a heater, and an outdoor unit of an air conditioner including the humidifying unit.

Abstract

La présente invention vise une unité d’humidification, qui permet de réchauffer rapidement un agent d'adsorption, et un appareil extérieur de climatiseur. L’unité d’humidification discontinue (2) est disposée à l’extérieur d’une pièce et fournit de l’air humidifiant à l’intérieur de la pièce par une conduite. L’unité d’humidification (2) comprend l’agent d’adsorption (4), un radiateur (5) et un couvercle de radiateur (6). L’agent d’adsorption (4) adsorbe l’humidité dans l’air. Le radiateur (5) chauffe l’agent d’adsorption (4) pour désorber l’humidité adsorbée dans l’agent d’adsorption (4). Le radiateur (5) est positionné dans un espace fermé (11). Le couvercle de radiateur (6) forme au moins une partie d’un organe constituant un espace fermé qui forme l’espace fermé (11).
