Definitions

  • the present invention relates to a humidifying unit for collecting moisture from the air and humidifying, for example, air to be fed to inside of a room.
  • a humidifying unit shown in Figs. 5 and 6 has been provided as the above type of a humidifying unit.
  • This humidifying unit has a parallelepiped-shaped casing 1, in which there are disposed a discoid humidifying rotor 2 composed of adsorbents such as silicagel and zeolite, a moisture absorption fan 3 composed of a sirocco fan, a humidification fan 5 composed of a sirocco fan, an electric heater 6, a moisture absorption duct 7, and an electrical equipment box 8.
  • the humidifying rotor 2, the humidification fan 5 and the electric heater 6 are stacked in a vertical direction.
  • the heated air is humidified by passing through a humidification portion containing moisture in the humidifying rotor 2, and the humidified air is sucked by the humidification fan 5, i.e., the fan 5 of the humidification path Y beneath the humidifying rotor 2 and fed to inside of a room.
  • the humidifying rotor 2 and the humidification fan 5 are overlapped in a vertical direction, which causes a problem of larger thickness in the vertical direction.
  • the humidifying unit is mounted on the outdoor unit of an air conditioner in most cases, the larger thickness in the vertical direction prevents the humidifying unit from fitting in installation space.
  • the humidifying unit of the present invention comprises:
  • the humidifying rotor, the humidification fan, and the moisture absorption fan are disposed flatly so as not to overlap with each other, which achieves smaller thickness. This eliminates restriction on installation space of the humidifying unit.
  • the humidification path has a portion curved in an approximate U or J shape that leads humidified air sent from one face of the humidifying rotor to a face of the humidification fan on a side identical to the face of the humidifying rotor.
  • the humidification path has a portion curved in an approximate U or J shape, which makes it possible to lead humidified air from the humidifying rotor to the humidification fan with use of the portion curved in the U or J shape even in the case where the humidifying rotor and the humidification fan are not overlapped but disposed flatly.
  • providing the portion curved in the approximate U or J shape enables flat arrangement of the humidifying rotor and humidification fan.
  • an electrical equipment box is disposed between the humidifying rotor and the humidification fan, or between the humidifying rotor and the moisture absorption fan.
  • the electrical equipment box is disposed between the humidifying rotor and the humidification fan, or between the humidifying rotor and the moisture absorption fan. This enables effective use of space between the humidifying rotor and the humidification fan or the moisture absorption fan, thereby making the structure compact.
  • an electrical equipment box is not provided, and so electrical equipment is connected to electrical equipment inside an electrical equipment box of an outside unit.
  • the humidifying unit does not have an electrical equipment box, and so the electrical equipment box of the outside unit is shared by the humidifying unit, which simplifies the structure of the humidifying unit.
  • the humidifying unit is provided with a discoid humidifying rotor 12 in the center of an approximately parallelepiped-shaped casing 11.
  • the humidifying rotor 12 is composed of adsorbents such as silicagel, zeolite, and alumina formed in a honeycomb pattern or a porous multiparticle pattern.
  • the humidifying rotor 12 is rotated by an unshown thin motor.
  • a moisture absorption fan 13 composed of a sirocco fan on the left side of the humidifying rotor 12, and a humidification fan 15 composed of a sirocco fan on the right side of the humidifying rotor 12.
  • the humidifying rotor 12, the moisture absorption fan 13 and the humidification fan 15 are disposed flatly so as not to overlap with each other.
  • the humidifying rotor 12 On the upper side of the humidifying rotor 12, there is provided an electric heater 16 as heating means. Also, on the upper side of the humidification fan 15, there is provided an electrical equipment box 18. On the upper side of the humidifying rotor 12 and the moisture absorption fan 13, there is provided a moisture absorption duct 17 that forms part of a moisture absorption path X. In the moisture absorption path X, moisture-absorbed air flows as shown with an arrow X, while in a humidification path Z, humidified air flows as shown with an arrow Z. As shown in Fig. 2 , the humidification path Z has a portion Z1 curved in an approximate U or J shape. Consequently, humidified air sent from the humidifying rotor 12 is led to the humidification fan 15 by the portion Z1 curved in the U or J shape.
  • the heated air is humidified by passing through a humidification portion containing moisture in the humidifying rotor 12 to become humidified air, and the humidified air is sucked into the humidification fan 15, i.e., the fan 15 of the humidification path Z through the portion Z1 curved in the approximate U or J shape and then fed from the humidification fan 15 to inside of a room.
  • the humidifying rotor 12, the moisture absorption fan 13 and the humidification fan 15 are disposed flatly so as not to overlap with each other, which makes the humidifying unit thinner. Consequently, the height of the humidifying unit becomes smaller, thereby enabling installation of the humidifying unit in narrow space on the outdoor unit of an air conditioner.
  • the humidification path Z is provided with a portion Z1 curved in an approximate U or J shape. Consequently, even when the humidifying rotor 12 and the humidification fan 15 are not overlapped but disposed flatly, humidified air sent from the humidifying rotor 12 can be led to the humidification fan 15 through the portion Z1 curved in the U or J shape. More particularly, providing the portion Z1 curved in the approximate U or J shape enables flat disposition of the humidifying rotor 12 and the humidification fan 15.
  • Fig. 3 shows another embodiment, which is different only in arrangement of an electrical equipment box 28 from the embodiment shown in Figs. 1 and 2 . Therefore, component members similar to those in Figs. 1 and 2 are designated by similar reference numerals and description thereof will be omitted.
  • the electrical equipment box 28 is disposed in a space between the humidifying rotor 12 and the humidification fan 15.
  • Disposing the electrical equipment box 28 between the humidifying rotor 12 and the humidification fan 15 enables effective use of space between the humidifying rotor 12 and the humidification fan 15, thereby making the structure compact.
  • the electrical equipment box 28 is disposed between the humidifying rotor 12 and the humidification fan 15, the electrical equipment box may be disposed between the humidifying rotor 12 and the moisture absorption fan 13.
  • Fig. 4 shows still another embodiment, which does not have an electrical equipment box, and so the unshown electrical equipment is connected to the electrical equipment inside an electrical equipment box of an unshown outside unit of an air conditioner.
  • the humidifying unit does not have an electrical equipment box, and so the electrical equipment box of the outside unit is shared by the humidifying unit, which simplifies the structure of the humidifying unit.
  • the electric heater is used as a means of heating, a hot water heater or a condenser may be substituted for the electric heater.
  • the moisture absorption fan 13 and the humidification fan 15 are disposed downstream of the humidifying rotor 12, it may be disposed upstream of the humidifying rotor 12.
  • the moisture absorption fan and the humidification fan may be other than the sirocco fan.
  • the humidifying rotor, the humidification fan and the moisture absorption fan are disposed flatly so as not to overlap with each other, which makes the humidifying unit thinner, thereby achieving smaller installation space.
  • the humidification path has a portion curved in an approximate U or J shape, which makes it possible to lead humidified air from the humidifying rotor to the humidification fan with use of the portion curved in the U or J shape even in the case where the humidifying rotor and the humidification fan are not overlapped but disposed flatly.
  • providing the portion curved in the approximate U or J shape enables flat arrangement of the humidifying rotor and humidification fan.
  • the electrical equipment box is disposed between the humidifying rotor and the humidification fan, or between the humidifying rotor and the moisture absorption fan. This enables effective use of space between the humidifying rotor and the humidification fan or the moisture absorption fan, thereby making the structure compact.
  • the humidifying unit of one embodiment does not have an electrical equipment box, and so the electrical equipment box of the outside unit is shared by the humidifying unit, which simplifies the structure of the humidifying unit.
