  • the function and the structure of the humidifying/dehumidifying apparatus as well as the air flow will be described, with reference to a humidifying operation.
  • the air sucked in from the room is sucked through inlet 5 on the front surface of front panel 3 and inlet at an upper portion of body casing 2, and the air is guided to a left side surface of moisture absorbing rotor 39 through filter 13.
  • On both sides of moisture absorbing rotor 39 air flow paths are formed respectively at the angles as shown in Fig. 16, and a rubber packing having such a shape that slides over the rotor surface is provided for sealing, so as to prevent leakage of air at a portion that is in contact with the rotor.
  • the air sucked in by moisture absorbing rotor 51 passes through the area A having the area of 1/2 (180°) of the rotor side surface shown in Fig. 16 and, at this time, the water in the air is absorbed by the moisture absorbing substance applied on the rotor, so that after the passage through moisture absorbing rotor 39, the air is dry.
  • the dried air is passed through exhaustion duct 52 and discharged to the outside of the room, by the function of the sirocco fan, operated by the motor of moisture absorbing fan 51.
  • the air sucked in by the motor of recovery fan 41 passes through the areas B and D of Fig.
  • the moisture absorbing function of area D is small, as the area D follows the area C of moisture absorbing rotor 39 and the temperature of the ceramics as the material of the moisture absorbing rotor 39 is not yet sufficiently low.
  • the air which has passed through areas B and D is heated to a high temperature as it passes through recovery heater 42, and thereafter, the air passes from the right side surface of moisture absorbing rotor 39 through an area of 1/4 (90°) of the side surface of moisture absorbing rotor 39 of area C shown in Fig. 5, to the left side surface.
  • the water absorbed in the moisture absorbing substance on moisture absorbing rotor 39 is heated, and emitted from the moisture absorbing substance.
  • the air containing much moisture enters from the right side surface of moisture absorbing rotor 39 to the recovery fan 42, and blown out to the inside of the room through outlet 7.
  • the dried air is discharged to the outside of the room, and the moist is accumulated in the room, so that room is humidified.
  • the humidifying/dehumidifying apparatus 24 assembled in this manner allows manual inspection by touching the moisture absorbing rotor 39 through the cut-out 56b of case R56 in the process of assembly. Therefore, any problem can be found at an earlier stage, and if there should be a trouble, the time necessary for disassembly can significantly be reduced.
  • the driving motor 49 for moisture absorbing rotor 39 is mounted on the outside of the case, maintenance is possible without disassembly, and therefore, the loss of time is avoided.
  • the present invention provides a humidifying/dehumidifying apparatus which contains a rotating body of a moisture absorber absorbing and desorbing water in the air, a moisture absorbing fan sucking in the indoor air, a heater heating the air for desorbing water from the moisture absorber, and a recovery fan for feeding the heated air, in which the driving motor for rotating the rotating body of the moisture absorber is provided outside the case, and a cut-out is provided so that manual inspection by touching through the cut-out is possible, whereby any trouble can be found at an earlier stage, and even if there should be a trouble, the time for disassembly can significantly be reduced. Further, as the driving motor for the moisture absorbing rotor is mounted on the outside of the case, maintenance is possible without disassembly, and thus loss of time can be avoided.
  • a receiving portion receiving a driving gear transmitting rotational drive to the rotating body of the moisture absorber from the motor is provided on the side of the case on the same plane as the rotating body. Therefore, the state of engagement between the rotating body and the driving gear can be easily confirmed.
  • refrigerant pipes 71 and 72, a drain hose 73, a power line 74 and a ventilation duct 75 are drawn out from an indoor unit A (see Fig. 25) to the outside of the room through a pipe hole 77 provided in a wall 76 behind the indoor unit.
  • an auxiliary duct 78 such as shown in Figs. 17 and 18 is coupled to an outdoor side end of ventilation duct 75.
  • Auxiliary duct 78 is molded by a hard resin, for example, and has a coupling portion 79 to be coupled to ventilation duct 75, and an outlet side end 80 having an approximately semicircular shape. As is apparent from Fig. 20, outlet side end 80 is molded, twisted by about 90° from the coupling portion 79.
  • coupling portion 79 has an approximately semicircular shape as the cross sectional shape of ventilation duct 75 is approximately semicircular, the shape is not limited to semicircular, and the shape may be adapted in accordance with the cross sectional shape of ventilation duct 75.
  • a weather cover 81 for avoiding rain is mounted on an outdoor surface of wall 76, and various pipes, ventilation duct 75 and auxiliary duct 78 are guided to weather cover 81.
  • the air discharged from indoor unit A through ventilation duct 75 and auxiliary duct 78 are exhausted to the outside of the room through an outlet 82 of weather cover 81.
  • the coupling portion 79 of auxiliary duct 78 is adapted to be a coupling portion 79 of different diameters, having stepwise large diameter portion 79a and a small diameter portion 79b, so as to cope with a case where the pipe hole 77 is small and a ventilation duct 5 of small diameter must be used. Therefore, when the ventilation duct 75 to be coupled has a small diameter, it is possible to couple the auxiliary duct directly to the ventilation duct 75 by simply cutting the large diameter portion 79a.
  • outlet side end opening 83 of auxiliary duct 78 is cut obliquely, and therefore, when the duct is guided to weather cover 81 and brought into contact with the wall surface of weather cover 81, circulation of the air is not hindered, and good state of ventilation is ensured.
  • the outlet side end opening 83 is cut obliquely upward in the shown example, the direction is not limited as long as the opening is cut obliquely.
  • an auxiliary duct having an approximately semicircular outlet side end twisted by about 90° with respect to a coupling portion of the ventilating duct is coupled to an outdoor side end of the ventilation duct. Therefore, even when it is necessary to bend various pipes to cross the longitudinal axis of the ventilation duct, it becomes possible to bend the pipes not passing between an outlet end surface of the ventilation duct and the weather cover. Therefore, decrease in circulation efficiency of the air passing through the ventilation duct can be prevented.
  • the coupling portion for coupling the auxiliary duct to the ventilation duct is adapted to be a coupling portion having cross sections of different diameters, it is unnecessary to prepare a separate auxiliary duct even when a pipe hole through which the ventilation duct is passed is small and a ventilation duct of a small size is necessary.
