(First embodiment)
Hereinafter, a first embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 shows an outline of the structure of a dehumidifying / humidifying device 100 according to the first embodiment of the present invention, where (a) is a plan view and (b) is a state in which the dehumidifying / humidifying device 100 is disposed in a ceiling 50 of a vehicle. It is side surface sectional drawing. In the present embodiment, the dehumidifying / humidifying device 100 is mounted in the ceiling 50 of the vehicle, and the air in the passenger compartment is taken in and the dehumidified air and the humidified air are blown out.

  First, the structure of the dehumidifying / humidifying device 100 will be described in detail. As shown in FIGS. 1A and 1B, the dehumidifying / humidifying device 100 is configured by connecting a blower (blower unit) 2 to one end of a casing 1 molded with resin as a flow path through which air flows. Yes. The blower 2 includes a flat scroll casing 20 formed of a resin, a centrifugal multiblade fan (sirocco fan) 21 disposed therein, and a blower motor 22 that drives the fan 21. The vehicle interior air is sucked from a suction port 23 opened below the scroll casing 20 and blown out from a blower outlet 24.

  The blower outlet 24 of the blower 2 is connected to the suction port 10 of the casing 1, and supplies the sucked vehicle interior air into the casing 1. In the casing 1, the adsorbent module 3 and the flow path switching unit 4 are sequentially arranged along the air flow direction. The casing 1 can be designed in various shapes depending on the installation location. As described above, since it is installed in the ceiling 50, the casing 1 is a flat, substantially rectangular parallelepiped box shape in which the thickness corresponding to the height is designed to be thin. Formed. Note that the outer shape in the thickness direction, the length direction, and the width direction of the casing 1 may be formed in a curved shape according to the shape of the ceiling 50.

  At the downstream end of the air flow of the casing 1, a humidified air outlet 8 for blowing humidified air and a dehumidified air outlet 9 for blowing dehumidified air are provided side by side in the width direction. The humidified air outlet 8 and the dehumidified air outlet 9 are defined by a partition wall (second partition portion) 11 formed integrally with the casing 1, and in this embodiment, the humidified air outlet 9 is provided with respect to the dehumidified air outlet 9. 8 is formed small. In addition, in order to reduce pressure loss, these blower outlets 8 and 9 may be provided with the cross-sectional shape comprised by a curve.

  Next, the adsorbent module 3 of this embodiment will be described with reference to FIG. FIG. 2 is a perspective view showing an example of the adsorbent module 3 in FIG. The adsorbent module 3 does not require a driving mechanism and uses a high thermal efficiency. That is, as shown in FIG. 2, the adsorbent module 3 grips the adsorbent with the Peltier element 30 having a pair of plate surfaces 30a and 30b that respectively function as a heat absorbing portion and a heat radiating portion, and a fin 33 that can be ventilated. And a first adsorbing element 31A and a second adsorbing element 31B arranged directly on the plate surfaces 30a and 30b of the Peltier element 30, respectively.

  As is well known, the Peltier element 30 is an element that uses the Peltier effect, and is an electronic component that is used as a cooling device for electronic devices such as computers. That is, in the Peltier device, a large number of P-type semiconductors and N-type semiconductors are arranged between two types of metal plates, one metal plate forms an NP junction, and the other metal plate forms a PN junction. In such an element, heat transfer occurs when an electric current is passed through the PN junction, an endothermic phenomenon occurs in one metal plate, and a heat dissipation phenomenon occurs in the other metal plate.

  The adsorbing elements 31A and 31B are made of a metal having good thermal conductivity such as aluminum, and a large number of fins 33 are provided on the substrate 32 in contact with the plate surfaces 30a and 30 of the Peltier element 30 along the ventilation direction. It is set. The adsorbing elements 31A and 31B are each configured by gripping an adsorbing material on the fin 33 that can be ventilated, and are usually formed in a flat box shape in order to be accommodated in the thin casing 1 described above.

  As the fin 33, various structures can be used as long as the fin 33 can be reduced in size and a large adsorption area can be secured and a larger amount of powdery adsorbent can be held. As the structure of such fins, for example, the so-called corrugated type in which the opening shape of the ventilation cell is formed in a substantially triangular shape by a corrugated sheet, the honeycomb type in which the opening shape of the ventilation cell is formed in a substantially hexagonal shape, A lattice-type structure in which the opening shape of the ventilation cell is formed in a square shape may be used.

  In the present embodiment, the adsorbent satisfying the characteristics is preferably zeolite that can easily adsorb water vapor at a low humidity and can easily desorb at a low temperature. In the adsorbent module 3, the adsorbing elements 31 </ b> A and 31 </ b> B are heated and cooled by the Peltier element 30 with no air layer or other heat insulating elements interposed between the plate surfaces 30 a and 30 b of the Peltier element 30. May be disposed so as to be transmitted by heat conduction, and may be disposed through a heat conductive material such as silver paste or heat transfer grease.

  In addition, the adsorbent module 3 may be formed in a flat rectangular parallelepiped as shown in FIG. 2, or may be formed in a shape having a curved surface according to the structure of the casing. As shown in FIG. 1, the adsorbent module 3 is disposed in the casing 1 so that air sent by the blower 2 can pass through the adsorbing elements 31 </ b> A and 31 </ b> B. In the present embodiment, in order to reduce the size of the adsorbent module 3, for example, a flat Peltier element 30 in which the plate surfaces 30 a and 30 b respectively function as a heat absorbing portion and a heat radiating portion is used.

  Further, in each of the adsorption elements 31A and 31B, the ventilation area (total opening area orthogonal to the ventilation direction of the fins 33) is the minimum cross-sectional area of the upstream and downstream flow paths of the adsorbent module 3. It is preferably set to be equal to or greater than (opening area perpendicular to the ventilation direction). When the ventilation areas of the adsorption elements 31A and 31B are set as described above, the flow velocity of air passing through the adsorption elements 31A and 31B can be reduced, and the adsorption and desorption functions can be further enhanced. .

  Furthermore, each adsorption element 31A, 31B may be formed so that the area of the cross section orthogonal to the internal ventilation direction is larger than the opening area of the air inlet and outlet. As described above, when the cross-sectional area inside the adsorption elements 31A and 31B is increased, the pressure loss during ventilation in the side edge portion on the width direction side (left and right in plan view) near the entrance / exit can be reduced. The adsorption / desorption efficiency in each adsorption element 31A, 31B can be increased.

  In the dehumidifying / humidifying device 100 of this embodiment, in the adsorbent module 3 described above, the adsorption operation and desorption operation of the adsorption elements 31A and 31B are alternately switched every 5 to 10 minutes. Therefore, in this embodiment, since the humidified air is continuously blown out from the humidified air outlet 8 and the dehumidified air is continuously blown out from the dehumidified air outlet 9, as shown in FIG. The flow path switching unit 4 is disposed on the downstream side.

  As a mechanism for switching the air flow path, a mechanism that moves two flexible pipes to change the connection destination, two shutters that are operated synchronously by a link or the like are alternately opened and closed, and the connection destination is changed. A mechanism to change can also be used. However, from the viewpoint of simplifying the device configuration and reducing the size, as shown as an example in FIG. 1, the flow path switching unit 4 is directed to each air by a flow path switching door 6 that is rotated by an actuator 7. Is to be switched.

  First, as shown in FIG. 1B, the flow path switching unit 4 causes the first adsorption element 31 </ b> A to be moved by a partition plate (first partition unit) 40 disposed immediately downstream of the adsorbent module 3. It is partitioned into a first inflow space 3A into which the air that has passed in and a second inflow space 3B into which the air that has passed through the second adsorption element 31B flows.

  Further, as shown in FIG. 1A, the downstream side of the partition plate 40 flows out to the humidified air flow passage 80 flowing out to the humidified air outlet 8 and to the dehumidified air outlet 9 by the partition wall 11 integrally formed with the casing 1. The dehumidifying air flow passage 90 is partitioned, and the cross-sectional area of the humidifying air flow passage 80 is smaller than the dehumidifying air flow passage 90. Thereby, the air volume of the humidified air blown out from the humidified air outlet 8 is smaller than the air volume of the dehumidified air blown out from the dehumidified air outlet 9.

  The flow path switching door 6 is disposed between the partition plate 40 and the partition wall 11, and one shaft (rotating shaft) 60 passes through the entire width of the casing 1. Specifically, the configuration and operation of the flow path switching unit 4 of the present embodiment will be described with reference to FIGS. FIGS. 3A and 3B show an example of the flow path switching door 6 in FIG. 1, in which FIG. 3A is a perspective view, and FIG. 3B is a view as viewed in FIG.

  As shown in FIG. 3, the flow path switching door 6 connects the humidified air flow passage 80 and one of the first inflow space 3A and the second inflow space 3B to the shaft 60 and closes the other. The humidifying side doors 61a and 61b, which can reverse the state of the air, the dehumidifying air flow passage 90 and one of the first inflow space 3A and the second inflow space 3B are connected to each other and the other is closed, and this communication / blocking state is reversed. The dehumidifying side doors 62a and 62b that can be used are integrally provided.

  In addition, the door area of the humidification side doors 61a and 61b and the dehumidification side doors 62a and 62b is substantially proportional to the passage cross-sectional area of both the flow paths 80 and 90, and the dehumidification side doors 62a and 62b are large, and the humidification side door 61a. 61b is smaller. A lever plate 63 for rotating the flow path switching door 6 is provided on one end side of the shaft 60, and the casing 1 is divided into two vertically so that the lever plate 63 comes out of the casing 1. It is made to be pinched by. On the outer surface of the casing 1, an actuator 7 such as a servo motor that is connected to the end side of the lever plate 63 and switches the flow path switching door 6 is disposed.

  Moreover, in this embodiment, in order to reduce the rotation range of the flow path switching door 6 (about 60 degrees in this embodiment), two humidifying doors and two dehumidifying doors are formed. One humidifying door and one dehumidifying door are formed at opposing positions (for example, 61a and 62a or 61b and 62b in FIG. 3B), and the positions where the respective doors are closed are switched 180. It is good also as a structure rotated degree. Although the rotation range of the door becomes large, the shape of the door can be simplified.

  4 and 5 are diagrams for explaining the mechanism of channel switching. Each (a) is a cross-sectional view taken along line aa in FIG. 1 (a), and (b) is b in FIG. 1 (a). It is -b sectional drawing. FIG. 4 shows a state of the first flow path switching position. By rotating the flow path switching door 6 to one side (the state of FIG. 4), the first inflow space 3A and the dehumidified air flow passage 90 are connected. The second inflow space 3B and the humidified air flow passage 80 are communicated with each other.

  That is, on the side of the humidified air outlet 8 in FIG. 4A, the humidified air that has flowed out into the second inflow space 3B flows out into the humidified air outlet 8 as it is, and the dehumidified air that has flowed out into the first inflow space 3A Since the flow path to the outlet 8 is closed by the humidifying side door 61b, the flow flows in the first inflow space 3A toward the front side of the drawing, moves to the dehumidifying air flow passage 90 side, and flows out from there to the dehumidifying air outlet 9. become.

  Similarly, on the side of the dehumidifying air outlet 9 in FIG. 4B, the dehumidifying air flowing out into the first inflow space 3A flows out into the dehumidifying air outlet 9 as it is, and the humidified air flowing out into the second inflow space 3B is dehumidified. Since the flow path to the air outlet 9 is closed by the dehumidifying side door 62b, it flows in the second inflow space 3B to the back side of the page, moves to the humidified air flow passage 80 side, and flows out from there to the humidified air outlet 8. It becomes like this.

  FIG. 5 shows the state of the second flow path switching position. By rotating the flow path switching door 6 to the other side (the state of FIG. 5), the first inflow space 3A and the humidified air flow passage 80 are connected. The second inflow space 3 </ b> B and the dehumidifying air flow passage 90 communicate with each other. That is, on the side of the humidified air outlet 8 in FIG. 5A, the humidified air that has flowed out to the first inflow space 3A directly flows out to the humidified air outlet 8, and the dehumidified air that has flowed out to the second inflow space 3B Since the flow path to the outlet 8 is blocked by the humidifying side door 61a, the flow flows in the second inflow space 3B toward the front side of the drawing, moves to the dehumidifying air flow passage 90 side, and flows out from there to the dehumidifying air outlet 9. become.

  Similarly, on the side of the dehumidifying air outlet 9 in FIG. 5B, the dehumidifying air flowing out into the second inflow space 3B directly flows out into the dehumidifying air outlet 9, and the humidified air flowing out into the first inflow space 3A is dehumidified. Since the flow path to the air outlet 9 is closed by the dehumidifying side door 62a, it flows in the first inflow space 3A to the back side of the paper surface, moves to the humidified air flow passage 80 side, and flows out from there to the humidified air outlet 8 It becomes like this.

  In the adsorbent module 3, the direction of the current flowing in the Peltier element 30 is reversed at a time interval according to the adsorption / desorption operation of each adsorption element 31 </ b> A, 31 </ b> B, for example, at intervals of 5 to 10 minutes. The heat absorption function and the heat dissipation function in 30a and 30b are interchanged.

  Further, in the flow path switching unit 4, the flow path switching door 6 is rotated according to the reversal of the current of the Peltier element 30, and the destination of each air processed by the adsorbent module 3 is humidified. The other air is switched from the dehumidifying air outlet 9 to the humidified air outlet 8 from the air outlet 8.

  The operation timing of the flow path switching door 6 is from when the current of the Peltier element 30 is reversed until the temperature of the plate surfaces 30a and 30b of the Peltier element 30 is reversed between high and low. Thereafter, about 30 to 60 seconds elapse. In this way, dehumidified air and humidified air can be generated more efficiently by operating the flow path switching door 6 and switching the destination after a while after the current reversal.

  Although not shown, the dehumidifying / humidifying device 100 of the present embodiment is for controlling the blower 2, controlling the current of the Peltier element 30 in the adsorbent module 3, and controlling the actuator 7 in the flow path switching unit 4. A control device is provided. And this dehumidifying / humidifying device 100 is arrange | positioned in the ceiling 50 between the top plate 50a of a vehicle, and the interior material 50b, as shown in FIG.1 (b).

  An integrally formed air duct 70 is connected to the humidified air outlet 8 and the dehumidified air outlet 9 of the dehumidifying / humidifying device 100. The humidified air outlet 70a of the air duct 70 communicated with the humidified air outlet 8 is directed from the ceiling 50 to the occupant Dr in the passenger compartment. The dehumidifying air outlet 70b of the air duct 70 communicating with the dehumidifying air outlet 9 is directed to the space in the ceiling 50 between the top board 50a and the interior material 50b.

  The dehumidifying / humidifying device 100 of this embodiment operates as follows, for example, in the winter when the outside air is dry. In other words, the blower 2 sucks air in the passenger compartment and sends it to the first adsorption element 31A and the second adsorption element 31B of the adsorbent module 3, respectively. In the adsorbent module 3, for example, one plate surface 30a of the Peltier element 30 functions as a heat absorbing portion, and the other plate surface 30b functions as a heat radiating portion.

  For this reason, the first adsorbing element 31A is cooled by the plate surface 30a, the adsorbing operation of the adsorbent held by the fin 33 proceeds, and the water vapor in the air passing through the fin 33 is adsorbed. On the other hand, the second adsorption element 31B is heated by the plate surface 30b of the Peltier element 30, and the desorption operation of the adsorbent held by the fins 33 of the second adsorption element 31B proceeds and passes through the fins 33. Releases water vapor into the air.

  The air that has been dehumidified through the first adsorbing element 31A of the adsorbent module 3 flows out into the first inflow space 3A, and the air that has been humidified through the second adsorbing element 31B into the second inflow space 3B. The air that has flowed out and is humidified by the flow path switching door 6 is directed to the humidified air flow passage 80 and blown out from the humidified air outlet 8, and the dehumidified air is directed to the dehumidified air flow passage 90 and blown out from the dehumidified air outlet 9 Is done.

  In the adsorbent module 3, when the adsorption operation and the desorption operation are performed for a predetermined time, the voltage applied to the Peltier element 30 is reversed, and the heat absorption part and the heat dissipation part of the Peltier element 30 are switched. In other words, the plate surface 30a of the Peltier element 30 functions as a heat dissipation portion, and the plate surface 30b functions as a heat absorption portion. Then, by switching the functions of the plate surfaces 30a and 30b of the Peltier element 30, the adsorption / desorption operation of the adsorbent is reversed in each of the adsorption elements 31A and 31B.

  That is, the first adsorbing element 31A desorbs the water vapor that has been adsorbed until the fin 33 that has been cooled is heated. On the other hand, said 2nd adsorption | suction element 31B starts adsorption | suction of water vapor | steam, when the fin 33 which was heated is cooled. As a result, the first adsorbing element 31A releases and vaporizes water vapor into the air passing therethrough, and the second adsorbing element 31B adsorbs and dehumidifies the water vapor in the air passing therethrough. Thereby, the humidified air flows out to the first inflow space 3A, and the dehumidified air flows out to the second inflow space 3B.

  When the voltage applied to the Peltier element 30 is reversed, the flow path switching door 6 rotates from the first flow path switching position to the second flow path switching position to switch the flow path. That is, the flow path switching door 6 is switched from, for example, the state shown in FIG. 4 to the state shown in FIG. For this reason, the air humidified through the first adsorbing element 31A of the adsorbent module 3 flows out into the first inflow space 3A, and the air dehumidified through the second adsorbing element 31B is in the second inflow. The air that has flowed out into the space 3B and is humidified by the flow path switching door 6 is directed to the humidified air flow passage 80 and blown out from the humidified air outlet 8, and the dehumidified air is directed to the dehumidified air flow passage 90 and dehumidified air blown It blows out from the exit 9.

  In the dehumidifying / humidifying device 100 of the present embodiment, the adsorption / desorption operation is reversed at a certain timing in the adsorbent module 3 as described above, and according to this, the dehumidified air and the humidified air are The blowing channel is switched by the channel switching door 6. Thereby, the dehumidified air can be continuously blown out from the dehumidified air outlet 9, and the humidified air can be continuously blown out from the humidified air outlet 8. The humidified air is used to improve the comfort of the occupant Dr, and the dehumidified air is discharged to the ceiling 50 space.

  As described above, in the dehumidifying / humidifying device 100 according to the present embodiment, each of the plate surfaces 30a functioning as a heat absorbing part and a heat radiating part of the Peltier element 30 using the pair of fixed adsorbing elements 31A and 31B holding the adsorbent. The adsorbent module 3 is configured by being arranged directly on 30b. In the adsorbent module 3, the heat absorption part and the heat dissipation part are functionally switched by reversing the current flowing to the Peltier element 30, and the adsorption operation and the desorption operation are reversed by switching the cooling and heating for the adsorption elements 31A and 31B. The flow path switching door 6 is used to switch the destination of the air that has passed through the first adsorption element 31A and the air that has passed through the second adsorption element 31B according to the reversal of the adsorption operation and the desorption operation.

  Therefore, in the dehumidifying / humidifying device 100 of the present embodiment, it is not necessary to provide a rotation drive unit as in the conventional suction rotor system, and the suction elements 31A and 31B are directly arranged on the Peltier element 30, Since the thermal conductivity between the Peltier element 30 and the adsorption element when heating / cooling the elements 31A and 31B is high, the adsorption elements 31A and 31B and the Peltier element 30 can be further downsized. As a result, the apparatus configuration can be simplified and the entire apparatus can be further reduced in size.

  Next, the features and effects of this embodiment will be described. The casing 1 is disposed in the ceiling 50 between the top plate 50a and the interior material 50b of the vehicle, and the humidified air blown from the humidified air outlet 8 is blown out around the vehicle occupant Dr, and from the dehumidified air outlet 9 The dehumidified air blown out is blown into the ceiling 50.

  According to this, since the dehumidified air does not enter the vehicle interior, it is possible to prevent the dehumidified air from entering the suction port 23 of the dehumidifying / humidifying device 100 and deteriorating the humidifying performance. In addition, since the dehumidifying air outlet is not opened in the vehicle interior, the blowing sound (direct sound) of the dehumidifying air can be eliminated, and the odor of the dehumidifying air is not felt by the passenger. Furthermore, it is possible to prevent condensation in the ceiling 50 at a low outside temperature such as in winter.

  Moreover, the humidified air outlet 71a can be configured at an appropriate position. Moreover, the ventilation sound (direct sound) of humidified air can be reduced through the humidified air duct 71. In addition, you may provide the wind direction adjustment means which adjusts the direction of blowing air, such as a manual louver, in the blowing end 71a of the humidification wind duct 71, for example.

  Further, a dehumidifying air duct 72 for sending dehumidifying air blown from the dehumidifying air outlet 9 is disposed in the ceiling 50, and the dehumidifying air is blown out from the dehumidifying air duct 72 toward the inner surface of the windshield 51 of the vehicle. . According to this, the dehumidified air can be used for anti-fogging of the windshield 51. Moreover, by setting it as the structure which blows off toward the inner surface of the windshield 51 via the dehumidification wind duct 72, the blowing ends 72a and 72b of dehumidification wind can be comprised in an appropriate position. Furthermore, the blowing sound (direct sound) of the dehumidified air can be reduced through the dehumidified air duct 72.

  Further, the dehumidifying air is blown out toward the upper left and right portions of the windshield 51. According to this, the front end portion of the dashboard, that is, the clouding of the upper right and left sides of the windshield 51 that is difficult to clear with the defroster blowing wind of the vehicle air conditioner blown from the lower end side of the windshield 51 is efficiently cleared.

(Other embodiments)
The present invention is not limited to the above-described embodiments, and can be modified or expanded as follows. For example, although not shown, in the dehumidifying / humidifying device 100 of the present embodiment, the first adsorbing element 31A of the adsorbent module 3 is disposed downstream of the adsorbent module 3 in order to blow out more comfortable air to the passenger side. A heat exchanger that performs heat exchange between the dehumidified (or humidified) air and the air humidified (or dehumidified) by the second adsorption element 31B may be arranged.

  This is because the humidified air blown out from the humidified air outlet 8 toward the driver Dr is air containing moisture desorbed in the adsorption elements 31A and 31B, but the heat of the Peltier element 30 at the time of heat desorption In some cases, the temperature may be higher than necessary. On the other hand, the dehumidified air blown from the dehumidified air outlet 9 toward the windshield 51 is cooled by the Peltier element 30. Therefore, in the present embodiment, a heat exchanger may be disposed on the downstream side of the adsorbent module 3, and the temperature of the humidified air may be lowered and the temperature of the dehumidified air may be increased by the heat exchanger.

  The heat exchanger includes a block-like sensible heat exchanger made of a metal having high thermal conductivity such as aluminum and having a number of fins on the surface, and a plurality of parallel plates made of the same metal as described above. In addition, various heat exchangers such as a sensible heat exchanger such as an orthogonal heat exchanger in which high temperature air and low temperature air are allowed to flow adjacent to each other between adjacent flat plates can be used.

  Such a heat exchanger is disposed across the flow path leading to the humidified air outlet 8 and the flow path leading to the dehumidified air outlet 9. When the above heat exchanger is arranged, heat can be exchanged between the humidified air with a high temperature and the dehumidified air with a low temperature. For example, in winter, the air is humidified and has a moderately lowered temperature. Can be blown out to the passenger side.

  Furthermore, the arrangement position of the heat exchanger is preferably downstream of the flow path switching door 6. When the heat exchanger is arranged on the downstream side of the flow path switching door 6, compared with the case where it is disposed between the adsorbent module 3 and the flow path switching door 6, the high-temperature air and the low-temperature air in the heat exchanger Since there is no change in the flow path and there is no heat loss in the heat exchanger itself, heat can be exchanged efficiently, and the temperature of the humidified air blown out to the passenger can be lowered.

  In this embodiment, in order to lower the temperature of the humidified air blown from the adsorbent module 3 and increase the temperature of the dehumidified air, although not shown, heating using a Peltier element on the downstream side of the adsorbent module 3 A cooler may be arranged. The heating / cooling device includes a Peltier element having a pair of plate surfaces each functioning as a heat absorbing portion and a heat radiating portion, a heat exchange fin that can be ventilated, and is disposed on each plate surface of the Peltier element. The heat exchange element and the second heat exchange element.

  As the structure of each fin of the first heat exchange element and the second heat exchange element, a structure such as a corrugated type, a honeycomb type, or a lattice type can be used as in the adsorbent module 3. The heating / cooling device is positioned downstream of the flow path switching door 6 or between the adsorbent module 3 and the flow path switching door 6. Although the thing of various structures can be used as the flow-path switching door 6, the apparatus similar to the above-mentioned apparatus shown in FIG. 1, for example is used.

  And when arrange | positioning a heating / cooling device in the downstream of the flow-path switching door 6, the flow-path switching door 6 is arrange | positioned in the reverse direction to the case of FIG. Humidified air and dehumidified air can be introduced into the downstream heating / cooling device by distributing to the left and right according to (not shown). In addition, when arrange | positioning in this way, since there is little temperature change in a heating cooler, a heat loss can be made small.

  The dehumidifying / humidifying device 100 of the present embodiment switches the current of the Peltier element in synchronism with the switching operation of the adsorbent module 3 in the above-described heating / cooling device, and the first heat exchange element and the second heat exchange element By switching between heating and cooling in, the temperature of the humidified air sent out from the adsorbent module 3 can be reliably increased, and the temperature of the dehumidified air can be reliably reduced. Moreover, the temperature of humidified air and dehumidified air can be adjusted by controlling the electric current of a Peltier device as needed.

  Note that the dehumidifying / humidifying device 100 of the present embodiment operates the air dehumidified from the humidified air outlet 8 in a situation where the outside air is at high humidity, for example, in the summer by switching the operation setting of the flow path switching door 6. Can also be blown out to the person Dr. Further, a deodorizing filter may be disposed on the upstream side or the downstream side of the adsorbent module 3 in order to capture odor components in the passenger compartment.
