  Next, the operation of the vehicle dehumidifying / humidifying device 10 according to an embodiment of the present invention will be described.

  FIG. 2 is an explanatory diagram for explaining the operation of the vehicle dehumidifying / humidifying device 10 according to one embodiment of the present invention. FIG. 4 shows a vehicle dehumidifying / humidifying device according to one embodiment of the present invention. The flow of 10 operations is shown in the flowchart.

  In the vehicle dehumidifying / humidifying device 10 shown in FIG. 1, when the occupant P switches on the activation switch 46 provided on the operation panel 16, an activation signal is output from the operation panel 16 to the control unit 18. When detecting the activation signal from the operation panel 16, the control unit 18 starts processing of the program shown in the flowchart of FIG.

  When the control unit 18 starts the processing of this program, it first detects an operation signal from the air conditioner 48 (step S1). Then, the control unit 18 performs the defroster mode in which the air conditioner 48 blows the conditioned air toward the front window 32 based on the operation signal from the air conditioner 48 or the air conditioning toward the feet of the passenger P and the front window 32. It is determined whether or not the foot differential mode for blowing wind is present (step S2).

  When the control unit 18 determines that the air conditioner 48 is not in the defroster mode or the foot differential mode (step S2: NO), the control unit 18 operates the dehumidifying / humidifying unit 14 as follows (step S3).

  That is, the control unit 18 connects the first switching damper 42 shown in FIG. 3 with the adsorbent 38A and the second outlet 26 of the pair of adsorbents 38A and 38B, and the adsorbent 38B and the second switching damper. The switching operation is performed so as to be in a state of being in communication with 43. Further, the control unit 18 switches the second switching damper 43 so that the first air outlet 24 is selected from the first air outlet 24 and the third air outlet 28, and this first air outlet 24 24 is in communication with the adsorbent 38B through the first switching damper 42. Further, the control unit 18 operates only one heater 40A of the pair of heaters 40A and 40B, and operates the pair of blowers 36A and 36B, respectively.

  As a result, as shown by the arrow A in FIG. At this time, air in a region 30 located in the vehicle longitudinal direction rear side in the vehicle interior with respect to the dehumidifying / humidifying unit 14 is sucked into the dehumidifying / humidifying unit 14 through the suction port 22.

  The air sucked from the suction port 22 is sent to each of the pair of adsorbents 38A and 38B shown in FIG. Also, one adsorbent 38A of the pair of adsorbents 38A and 38B releases the adsorbed moisture when the entire adsorbent 38A is heated by the heater 40A. Therefore, the air passing through the adsorbent 38A is humidified air containing moisture released from the adsorbent 38A. Then, the humidified air is sent to the first switching damper 42, guided to the second outlet 26 by the first switching damper 42, and from the second outlet 26 as shown by the arrow B in FIG. It is blown out around the face of the passenger P.

  Further, since the other adsorbent 38B of the pair of adsorbents 38A and 38B is not heated by the heater 40B, the air passing through the adsorbent 38B is dehumidified by the moisture adsorbed by the adsorbent 38B. The Then, the dehumidified air is sent to the second switching damper 43 via the first switching damper 42, guided to the first outlet 24 by the second switching damper 43, and as indicated by an arrow C1 in FIG. The air is blown out from the first air outlet 24 toward the front window 32. At this time, the first air outlet 24 and the second air outlet 26 are set apart from each other in the vehicle front-rear direction and the air outlet directions are different from each other. Are prevented from interfering with each other.

  The control unit 18 performs a switching operation as follows when a predetermined time has elapsed after the detection of the activation signal. That is, the control unit 18 operates the first switching damper 42 with the adsorbent 38B and the second air outlet out of the pair of adsorbents 38A and 38B in a state where the pair of blowers 36A and 36B shown in FIG. 26 is communicated, and the switching operation is performed so that the adsorbent 38A and the second switching damper 43 communicate with each other. Note that the control unit 18 maintains the second switching damper 43 so that the first air outlet 24 is selected from the first air outlet 24 and the third air outlet 28. Further, the control unit 18 stops one heater 40A of the pair of heaters 40A and 40B and activates the heater 40B.

  As a result, the other adsorbent 38B of the pair of adsorbents 38A and 38B releases the adsorbed moisture when the entire adsorbent 38B is heated by the heater 40B. Therefore, the air passing through the adsorbent 38B is humidified air containing moisture released from the adsorbent 38B. Then, the humidified air is sent to the first switching damper 42, guided to the second outlet 26 by the first switching damper 42, and from the second outlet 26 as shown by the arrow B in FIG. It is blown out around the face of the passenger P.

  Further, since one of the adsorbents 38A and 38B is not heated by the heater 40A being stopped, the air passing through the adsorbent 38A is adsorbed by the adsorbent 38A. Dehumidified air. Then, the dehumidified air is sent to the second switching damper 43 via the first switching damper 42, guided to the first outlet 24 by the second switching damper 43, and as indicated by an arrow C1 in FIG. The air is blown out from the first air outlet 24 toward the front window 32.

  In the vehicle dehumidifying / humidifying device 10 according to the embodiment of the present invention, the humidified air is supplied from the second outlet 26 by repeatedly generating the humidified air and the dehumidified air by the pair of adsorbents 38A, 38B. The air continuously blows around the face of the occupant P, and the dehumidified air is continuously blown from the first air outlet 24 toward the front window 32. In addition, at this time, the humidified air is blown out toward the passenger P, and at the same time, the dehumidified air is blown out toward the front window 32. As a result, a humidity distribution with different humidity is formed at both ends in the longitudinal direction of the vehicle without changing the absolute humidity in the passenger compartment.

  Then, when the vehicle dehumidifying / humidifying device 10 performs the above operation, when the occupant P selects and operates the defroster mode of the air conditioner 48, the air conditioner 48 enters the defroster mode, as shown by the arrow D in FIG. Air-conditioned air is blown out from the defroster outlet 50 toward the front window 32. When the foot def mode of the air conditioner 48 is selected and operated by the occupant P, the air conditioner 48 enters the foot def mode, and the conditioned air is blown toward the feet of the occupant P and the front window 32. When the defroster mode or the foot differential mode of the air conditioner 48 is selected and operated by the occupant P, an operation signal indicating the defroster mode or the foot differential mode is output from the air conditioner 48 to the control unit 18.

  The control unit 18 detects an operation signal from the air conditioner 48 while repeatedly performing the above-described steps S1 to S3 (step S1), and the air conditioner 48 blows conditioned air toward the front window 32. When it is determined that the defroster mode or the foot differential mode for blowing the conditioned air toward the feet of the occupant P and the front window 32 (step S2: YES), the dehumidifying / humidifying unit 14 is switched as follows. (Step S4).

  That is, the control unit 18 switches the second switching damper 43 shown in FIG. 3 so that the third outlet 28 is selected from the first outlet 24 and the third outlet 28. Thereby, the dehumidified air sent to the second switching damper 43 is guided to the third outlet 28 by the second switching damper 43, and as shown by the arrow C2 in FIGS. 2 (A) and 2 (B), The air is blown out from the third air outlet 28 toward the side window 34. Therefore, when the air conditioner 48 that air-conditions the passenger compartment is in the defroster mode or the foot differential mode, the conditioned air from the air conditioner 48 (arrow D) and the dehumidified air from the third outlet 28 (arrow C2) are different. It is prevented that they are blown in the direction and interfere with each other.

  As described above in detail, according to the vehicle dehumidifying / humidifying device 10 according to one embodiment of the present invention, the dehumidified air is blown out toward the suction port 22 and the front window 32 for sucking air in the passenger compartment. The first air outlet 24 is disposed on the opposite side in the vehicle front-rear direction, and a region 30 through which the air inlet 22 inhales air in the passenger compartment and a front window 32 through which the first air outlet 24 blows dehumidified air are also mutually connected. Located on the opposite side of the vehicle longitudinal direction. Therefore, the dehumidified air blown from the first outlet 24 can be suppressed from being sucked from the inlet 22, and moisture generated from the occupant P (for example, 25 g / hour per person) can be obtained from the inlet 22. The air in the rear side area in the vehicle front-rear direction in the vehicle interior is sucked. Thereby, in order to generate humid air, moisture in a vehicle interior can be used efficiently. As a result, the humid air can be reliably and continuously supplied to the passenger P.
