FIG. 2 is a schematic structural diagram of the inside of the dehumidifying / humidifying heating device 3.
In the dehumidifying / humidifying heater 3, a circulation air passage 5 and a discharge air passage 10 are provided separately from the circulation air passage 5.
In the circulation air passage 5, a circulation fan 6 composed of a large sirocco fan, a switching damper 7, a heater 8, and a dehumidifying rotor 9 are sequentially arranged from the upstream side to the downstream side, As the circulation fan 6 rotates, the air in the dehumidification / dehumidification target chamber 2 is sucked from the suction port 3a, blown to the dehumidification rotor 9 as hot air dried by the heater 8, and the moisture in the dehumidification rotor 9 is desorbed and desorbed. The high-temperature and high-humidity air containing the moisture is blown into the dehumidification / humidification target chamber 2 from the outlet 3b, and the dehumidification / humidification target chamber 2 can be humidified and heated by the high-temperature and high-humidity air.

The dehumidification rotor 9 is composed of a honeycomb-shaped rotor made of a hygroscopic material such as silica gel or zeolite. A part of the dehumidification rotor 9 is also disposed in the exhaust air passage 10, and the dehumidification rotor in the exhaust air passage 10 is arranged. On the upstream side of 9, a discharge fan 11 composed of a small sirocco fan is provided. A switching damper 12 is provided on the upstream side of the discharge fan 11, and intake pipes 20 and 21 are provided branched from the switching damper 12.
The exhaust fan 11 rotates in the exhaust air passage 10 so that the air passes through the dehumidification rotor 9, moisture is adsorbed by the dehumidification rotor 9, becomes dry air, and is sent downstream.

As shown in FIG. 1, the intake pipe 20 is connected to the ceiling of the drying chamber 1, and has a first intake port 13 a having a leading end communicating with the drying chamber 1. Is a second air intake 13b that penetrates the building wall W and is open to the outside.
Further, a damper 14 is provided on the downstream side of the dehumidification rotor 9 in the discharge air passage 10, and a discharge pipe 16 and a return pipe 19 are piped from the damper 14. The return pipe 19 has a tip at the tip. A first air outlet 15 a is formed through the side wall of the drying chamber 1 and opened in the drying chamber 1. Moreover, one discharge pipe 16 is the 2nd air blower outlet 15b which penetrated the building wall W and the front-end | tip opened outdoors.

  A humidity sensor 22 capable of detecting the humidity of the air flowing in the exhaust air passage 10 is provided near the downstream of the switching damper 12, for example, and a signal from the humidity sensor 22 is sent to a control unit (not shown). Accordingly, the control unit is configured to control the switching damper 12 and the switching damper 14 based on the detection signal from the humidity sensor 22.

  At the time of humidification operation for humidifying and heating the room 2 to be dehumidified, for example, when a towel wet in the drying chamber 1 is dried, a large amount of water vapor generated during drying is present in the drying chamber 1, The air containing water vapor is sucked into the intake pipe 20 from the first air intake port 13a, moisture in the water vapor is adsorbed by the dehumidification rotor 9 through the discharge air passage 10, and the first air is passed through the return pipe 19 as dried air. The dried air can be returned into the drying chamber 1 from the outlet 15a, and the drying chamber 1 can be efficiently dried.

  As described above, the dehumidification rotor 9 that has adsorbed moisture releases hot water heated by the heater 8 in the circulation air passage 5 to release water vapor, and the dehumidification / humidification target chamber 2 is heated and humidified air. The heated air blown out from the outlet 3b and containing a large amount of water vapor increases the sensible temperature in the dehumidification / dehumidification target chamber 2 so that the dehumidification / humidification target chamber 2 is well humidified and heated.

The exhaust pipe 16 is controlled to be discharged to the outside.

  Thus, based on the detection signal of the humidity sensor 22, the opening and closing of the dampers 12 and 14 are controlled via the control unit so that air is taken into the exhaust air passage 10 from the high humidity side during the humidifying operation. It can be controlled, moisture is efficiently obtained, water vapor can be used effectively for humidification in the room 2 to be dehumidified, the amount of heat escaping from the room is also reduced, energy is reduced, and the object to be dehumidified During humidification operation in the chamber 2, the towel T and the like can be satisfactorily dried while saving energy.

  The humidity sensor 22 is illustrated as being provided in the exhaust air passage 10 on the downstream side of the damper 12, but the humidity sensor 22 may be provided in the intake pipes 20 and 21, respectively. 1 air intake port 13a and second air intake port 13b may be provided respectively.
