Next, the form for implementing this invention is demonstrated using an Example.
FIG. 1 is a piping configuration diagram between a bathroom provided with a dehumidifying device and another room. In FIG. 1, a dehumidifying device 2 is installed on the ceiling of the bathroom 1 provided with a bathtub 1a, and a wash basin provided with a wash basin 3a. Regeneration air inlets 7a and 7b are provided on the ceiling of the toilet 3 equipped with the chamber 3 and the toilet 4a, and the regeneration air inlets 7a and 7b and the dehumidifier 2 are connected to each other through an intake pipe 5. It is.

The internal structure of the dehumidifier 2 is shown in the schematic diagram of FIG.
A circulation air passage 8 and a regeneration air passage 11 are separately provided in the dehumidifier 2, and a honeycomb structure dehumidification rotor 10 and a circulation fan 9 are provided in the circulation air passage 8. , The air in the bathroom 1 is sucked in through the suction port 2a and passed through the dehumidification rotor 10, so that moisture in the air is adsorbed by the dehumidification rotor 10 and dried into the bathroom 1 from the outlet 2b. It can be returned.

  In addition, a part of the dehumidification rotor 10 is disposed in the regeneration air passage 11, a regeneration heater 13 is provided on the upstream side of the dehumidification rotor 10, and a small regeneration fan 12 is provided on the upstream side thereof. Then, the rotation of the regeneration fan 12 sucks air into the regeneration air passage 11, heats the air with the regeneration heater 13, and blows the heated air onto the dehumidification rotor 10 to desorb moisture in the dehumidification rotor, The air containing water vapor can be discharged from the regeneration air outlet 6a communicated outdoors through the discharge pipe 6.

In this example, the switching damper 14 is provided at the upstream end of the regenerative air passage 11, and the intake pipes 5a and 5b are piped from the switching damper 14, and the leading end of the intake pipe 5a is the above-described washroom. 3 is an air inlet 7a for regeneration, and the tip of one intake pipe 5b is an air inlet 7b for reproduction opened in the toilet 4.
A humidity sensor 15a is provided in the vicinity of the regeneration air suction port 7a, and a humidity sensor 15b is provided in the vicinity of the regeneration air suction port 7b.

In the dehumidifying device 2 of the present example, the air taken into the regeneration air passage 11 can be selected and taken from either the washroom 3 or the toilet 4 during the dehumidifying operation.
That is, when the detection signals of the humidity sensor 15a and the humidity sensor 15b are transmitted to a control unit (not shown), the control unit compares the detection values of the humidity sensor 15a and the humidity sensor 15b and reproduces the air for regeneration on the low humidity side. A switching signal is sent to the switching damper 14 so as to open the suction port.

In FIG. 2, the humidity of the washroom 3 is lower than the humidity of the toilet 4, and the switching damper 14 is switched to open the regeneration air suction port 7a side, and the washroom 3 from the regeneration air suction port 7a. The low-humidity air is sucked into the regeneration air passage 11 through the intake pipe 5a.
Therefore, since the air sucked into the regeneration air passage 11 has a low humidity, the dehumidification rotor 10 can be efficiently regenerated. Therefore, the dehumidification drying time in the bathroom 1 can be shortened, and the bathroom 1 can be efficiently removed. It can be dehumidified.

  When the humidity sensor 15a and the humidity sensor 15b are compared with each other and it is determined that the humidity on the humidity sensor 15b side is low, the regeneration air inlet 7b on the toilet 4 side is switched by the switching damper 14. When opened, the air in the toilet 4 is sucked into the regeneration air passage 11.

That is, when the switching damper 14 is controlled so that the humidity of the air sucked when the regeneration air suction port 7a side is opened is detected by the humidity sensor 15c, and the switching damper 14 is opened to the regeneration air suction port 7b side. The humidity of the air sucked in is detected by the humidity sensor 15c, and the humidity when the regeneration air suction port 7a is opened is compared with the humidity when the regeneration air suction port 7b is opened. The regenerating air suction port 7a or the regenerating air suction port 7b is controlled to be continuously opened.
Therefore, also in the dehumidifying apparatus 2 of FIG. 3, the dehumidifying rotor 11 can be efficiently regenerated by sucking air from a room with low humidity, and the dehumidifying operation can be performed at a reduced running cost.

Next, in the dehumidifying device 2 shown in FIG. 4, a switching damper 16 is provided between the dehumidifying rotor 10 and the circulating fan 9 in the circulation air path 8, and the blower air path 19 is bypassed by the switching damper 16.

  In the dehumidifying device 2 of FIG. 4, when the air blowing operation is performed, the switching damper 16 is switched so that the air blowing path 19 side is opened, and the air in the bathroom 1 is blown from the suction port 2 a by the rotation of the circulation fan 9. The air is sucked into the passage 19 and blown into the bathroom 1 from the outlet 2b through the circulation air passage 8, and the ventilation damper 18 is further switched to open the ventilation air passage 18 side during the ventilation operation. The air in the bathroom 1 sucked through 19 can be discharged to the outside through the ventilation air passage 18.

  In this way, during the ventilation or ventilation operation, air is sucked through the ventilation air passage 19 and the air does not pass through the dehumidification rotor 10, so that no pressure loss occurs, and the efficiency of the circulation fan 9 is fully utilized. Good ventilation or ventilation can be achieved, and noise generation is reduced.

When performing the dehumidifying operation in the dehumidifying device 2 provided with such a blower air passage 19, the switching damper 16 is switched to the side for closing the blower air passage 19, as shown in FIG. 17 is switched to the side which closes the ventilation air path 18.
During this dehumidifying operation, as described above, the air in the bathroom 1 is sucked into the circulation air passage 8 through the dehumidifying rotor 10, dehumidified by the dehumidifying rotor 10, and returned to the bathroom 1 again. Further, the switching damper 14 is controlled by the detection signal of the humidity sensor 15c, the regeneration air suction port 7a of the low humidity chamber is opened, and the low humidity air is sucked into the regeneration air passage 11, The dehumidifying rotor 10 can be regenerated efficiently.

  In addition, in each said Example, although the case where the two intake pipes 5a and 5b were provided is illustrated, three or four intake pipes may be sufficient. In addition to the washroom 3 and the toilet 4, A regeneration air suction opening that opens to another chamber may be provided, and a chamber having the lowest humidity among the plurality of chambers may be selected and air may be taken into the regeneration air passage 11.

Furthermore, it is possible to provide both a humidity sensor and a temperature sensor, obtain the absolute humidity from the saturated water vapor amount with respect to the temperature, and perform switching control of the switching damper 14 based on the absolute humidity. Alternatively, a sensor that directly detects absolute humidity may be provided.
When both a humidity sensor and a temperature sensor are provided, or a sensor that detects absolute humidity is provided, select a more suitable air, such as giving priority to air with a low absolute humidity even at a slightly low temperature. It becomes possible.
