  In the above-described prior art, the humidified air passage of the air passage passes through the humidified air passage. Therefore, moisture remaining in the humidified air passage after the dehumidifying / humidifying device stops is condensed in the humidified air passage, and the dehumidifying / humidifying device is turned on again. There is a problem in that when the activated humidified air passes, the condensed water is scattered, smell is generated, and fungi are generated. As a means for solving such a problem, there is a method of newly adding a heating means for heating the humidified air passage so that the humidified air passage becomes equal to or higher than the dew point temperature. There is a problem that the physique becomes large and the configuration of the dehumidifying / humidifying device becomes complicated.

  Therefore, the present invention has been made in view of the above-described problems, and an object thereof is to provide a dehumidifying / humidifying device capable of preventing dew condensation in a humidified air passage with a simple configuration.

Not only the combination of the parts specifically described in each embodiment, but also the embodiments can be partially combined as long as the combination does not hinder.

(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan sectional view showing a dehumidifying / humidifying device 100 according to the first embodiment. FIG. 2 is a side sectional view of the dehumidifying / humidifying device 100. The dehumidifying / humidifying device 100 of the present embodiment is applied to, for example, a vehicle dehumidifying / humidifying device 100 that is mounted in a vehicle interior of a vehicle and takes in the vehicle interior air and blows out dehumidified air and humidified air. The dehumidifying / humidifying device 100 is used for supplying dehumidifying air for defogging to the inner surface side of the vehicle front window glass and supplying humidified air to the occupant side, for example, in winter when the outside air dries. The dehumidifying / humidifying device 100 is installed, for example, on a ceiling portion in a vehicle interior. The dehumidifying / humidifying device 100 includes a casing 1, a heat transfer unit 25, a blower 2, an adsorption module 3, a flow path switching unit 4, an actuator 7, and a control device (not shown).

  The casing 1 forms a flow path through which air flows. The casing 1 is formed in a longitudinal shape so as to extend along the flow direction in which air flows. In the casing 1, the adsorption 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. For example, the casing 1 is formed in a flat, substantially rectangular parallelepiped box shape in which a thickness portion corresponding to the height is designed to be thin in order to be installed on a ceiling in a vehicle interior. The Further, the casing 1 may be formed with a curved outer shape according to the ceiling shape. The casing 1 is made of resin, for example.

  Hereinafter, the direction in which the casing 1 extends and the direction in which air flows is referred to as the length direction Y (left-right direction in FIG. 1), and the direction orthogonal to the length direction Y is the width direction X (up-down direction in FIG. 1). The direction perpendicular to the length direction Y and the width direction X may be referred to as a thickness direction Z (direction perpendicular to the paper surface of FIG. 1).

  In the casing 1, a main passage 26, a humidified air passage 80 and a dehumidified air passage 90 are formed as passages through which air blown from the blower 2 flows. The main passage 26 is provided upstream of the humidified air passage 80 and the dehumidified air passage 90. The air that has passed through the main passage 26 is sent to the humidified air passage 80 and the dehumidified air passage 90, respectively.

  The humidified air passage 80 is formed by an inner wall portion of the casing 1 and is a passage through which air flows separately from the dehumidified air passage 90. In other words, the humidified air passage 80 and the dehumidified air passage 90 are formed as independent passages by the inner wall portion of the casing 1. Therefore, the humidified air flowing through the humidified air passage 80 does not flow through the dehumidified air passage 90. The other end of the casing 1 in the length direction Y (the left side in FIG. 1), which is the downstream end of the air flow, flows down the humidified air outlet 8 from which the humidified air that has flowed down the humidified air passage 80 and the dehumidified air passage 90 flow down. The dehumidified air outlet 9 from which the dehumidified air blown out is provided side by side in the width direction X.

The humidified air outlet 8 is connected to, for example, a face outlet duct (not shown) directed toward the passenger side, and the dehumidified air outlet 9 is connected to a defroster outlet duct (not shown) directed to, for example, a vehicle front window glass. ) Is connected.

  The blower 2 is a blowing means, and is provided at one end of the casing 1 in the longitudinal direction Y (right side in FIG. 1). The blower 2 is a centrifugal blower 2 including, for example, a multiblade fan 21, a radial fan, a turbo fan, and the like, and is configured to blow out the air sucked from the rotational axis direction outward in the radial direction. The blower 2 according to the present embodiment includes a flat scroll casing 20 formed of resin, a multi-blade fan 21 disposed therein, and a blower motor 22 that drives the multi-blade fan 21.

  The scroll casing 20 forms an outlet 24 for the multiblade fan 21 to send out air. The scroll casing 20 is a wall portion facing the radial direction of the multiblade fan 21. The scroll casing 20 surrounds the multiblade fan 21 from the outside in the radial direction, and forms a spiral flow path that gradually expands toward the air outlet 24.

  An opening 23 for allowing air from outside to flow into the scroll casing 20 is formed in the lower surface portion of the scroll casing 20 in the other thickness direction Z (downward in FIG. 2). As a result, the air flowing into the scroll casing 20 from the opening 23 is rectified in the radial direction and the circumferential direction by the spiral flow path, and is sent from the outlet 24 toward the other side in the length direction Y. The blower outlet 24 of the blower 2 is connected to the suction port 10 formed on one side in the length direction Y of the casing 1, and supplies the sucked air into the casing 1.

  Next, the adsorption module 3 will be described with reference to FIG. FIG. 3 is a perspective view showing the adsorption module 3. The adsorption module 3 is provided in the main passage 26. The adsorption module 3 is configured to allow air to pass through. The adsorption module 3 is air conditioning means, and humidifies and dehumidifies the air blown by the blower 2. The adsorption module 3 includes a Peltier element 30, a first adsorption element 31A, and a second adsorption element 31B.

  The Peltier element 30 is a plate-like thermoelectric element that utilizes the Peltier effect. When energized, the Peltier element 30 performs an endothermic action on the one end face side in the thickness direction Z and exerts a heat dissipating action on the other end face side in the thickness direction Z. It is. In the Peltier element 30, 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 Peltier element 30 is formed in a plate shape, and two plate surface portions 30a and 30b orthogonal to the thickness direction Z function as a heat absorbing portion and a heat radiating portion.

  The first adsorption element 31 </ b> A is provided on one plate surface portion 30 a in the thickness direction Z of the Peltier element 30. The second adsorption element 31B is provided on the other plate surface portion 30b in the thickness direction Z of the Peltier element 30. Since the first adsorbing element 31A and the second adsorbing element 31B have substantially the same configuration, only the first adsorbing element 31A will be described, and the description of the second adsorbing element 31B will be omitted. The first adsorption element 31 </ b> A adsorbs and releases moisture based on the temperature of one plate surface portion 30 a of the Peltier element 30. When the first adsorption element 31A is cooled, the amount of moisture absorption increases, absorbs moisture, and dehumidifies the passing air. Further, when the first adsorption element 31A is heated, the amount of moisture absorption is reduced, moisture is released, and the passing air is humidified.

  The first adsorption element 31 </ b> A includes a substrate 32 and fins 33, and an adsorption material is applied to the surfaces of the substrate 32 and the fins 33. The substrate 32 and the fins 33 are formed of a metal having excellent thermal conductivity such as aluminum. The board | substrate 32 is flat form, Comprising: It provides so that it may laminate | stack on the plate | board surface part 30a of the Peltier device 30. FIG. A plurality of fins 33 are provided to protrude outward from the substrate 32 in the thickness direction Z. A plurality of fins 33 are provided so as to extend along the length direction Y, and are provided so as to be separated in the width direction X.

  The adsorbent is preferably a material that readily adsorbs moisture at a low humidity and can be easily desorbed at a low temperature, such as zeolite. In the adsorption module 3, the adsorption elements 31 </ b> A and 31 </ b> B generate heat and cold generated by the Peltier element 30 with respect to the plate surface portions 30 a and 30 b of the Peltier element 30 without interposing an air layer or other heat insulation elements. It only needs to be disposed so as to be transmitted by conduction, and may be disposed via a heat conductive material such as silver paste or heat transfer grease.

  The adsorption module 3 is configured such that the direction of the current flowing in the Peltier element 30 is reversed at time intervals according to the adsorption and desorption operations of the adsorption elements 31A and 31B, for example, at intervals of 5 minutes to 10 minutes. Control is performed so that the heat absorption function and the heat radiation function in the surface portions 30a and 30b are interchanged. In the adsorption module 3, the direction of the current is reversed before the adsorption element on the heating side completely releases moisture.

  The heat transfer section 25 has thermal conductivity, and thermally connects the Peltier element 30 and the casing 1 that forms the humidified air passage 80. The term “thermally connected” means that the heat generated by the Peltier element 30 is transmitted to the humidified air passage 80, and the portion of the casing 1 that forms the humidified air passage 80 is configured to have a dew point or higher due to the heat of the Peltier element 30. . The heat transfer section 25 is provided on the outer wall 1 a of the portion of the casing 1 that forms the humidified air passage 80 and the portion of the casing 1 that forms the dehumidified air passage 90. The outer wall portion 1 a is synonymous with the outer peripheral surface portion of the casing 1.

  The heat transfer unit 25 is plate-shaped, and is provided along part of the both side portions in the thickness direction Z of the casing 1 along the outer wall portion 1 a of the casing 1. The heat transfer section 25 is preferably provided as a continuous member from a portion of the casing 1 where the adsorption module 3 is provided to a portion of the casing forming the humidified air passage 80. One end in the length direction Y of the heat transfer unit 25 is configured to reach a region where the adsorption module 3 is projected in the thickness direction Z. The other end in the length direction Y of the heat transfer section 25 is located up to the humidified air outlet 8 of the humidified air passage 80. Therefore, the heat transfer part 25 is also provided in the outer wall part 1a of the casing 1 in which the flow path switching part 4 is arranged.

  Further, the portion of the heat transfer section 25 provided on the adsorption module 3 is provided on the outer wall 1 a of the casing 1 so as to cover the entire adsorption module 3 when viewed from the thickness direction Z. In other words, the portion provided in the heat transfer unit 25 adsorption module 3 is configured to have substantially the same shape as the size in the width direction X and the length direction Y of the adsorption module 3.

  Therefore, the heat generated by the Peltier element 30 is transferred to the casing 1 via the fins 33 of the adsorption module 3, and the portion where the heat transferred to the casing 1 is provided in the adsorption module 3 of the heat transfer section 25 of the heat transfer section 25, in other words Then, it is transmitted to the length direction Y one part of the heat-transfer part 25. FIG. Thereafter, heat is transferred from one portion in the length direction Y of the heat transfer section 25 toward the other in the length direction Y, and is transferred to the other portion in the length direction Y of the heat transfer section 25, in other words, the humidified air outlet 8. Heat is transmitted to the portion of the casing 1 that forms the air passage 80.

  The heat transfer unit 25 is made of a material having excellent heat transfer properties, or a material containing copper or aluminum. The material containing copper includes pure copper and a copper alloy. The material containing aluminum includes pure aluminum and an aluminum alloy.

  As described above, the Peltier element 30 includes a plate surface portion that functions as a heat absorption portion and a plate surface portion that functions as a heat dissipation portion. However, since the Peltier element 30 as a whole has a relationship of cooling heat amount <heat dissipation amount, the Peltier element 30 As a whole, it always radiates heat to the outside. Therefore, the heat radiation amount of the Peltier element 30 is transmitted to the humidified air passage 80 via the heat transfer section 25, and the humidified air passage 80 is heated. Accordingly, the temperature of the humidified air passing through the humidified air passage 80 is set to the dew point or higher, so that dew condensation in the humidified air passage 80 can be prevented.

  Next, the flow path switching unit 4 will be described. FIG. 4 is a perspective view showing the flow path switching unit 4. FIG. 5 is a side view showing the flow path switching unit 4. The dehumidifying / humidifying device 100 alternately switches the adsorption operation and desorption operation of the adsorption elements 31A and 31B of the adsorption module 3 every 5 to 10 minutes. Therefore, in the present embodiment, 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, so that as shown in FIG. The flow path switching unit 4 is disposed on the side.

  The flow path switching unit 4 is a flow path switching means, and is configured to switch the destination of the air that has passed through the adsorption module 3. The flow path switching unit 4 distributes the air that has passed through the first adsorbing element 31A to the humidified air passage 80, and distributes the air that has passed through the second adsorbing element 31B to the dehumidified air passage 90, and the first adsorbing element The state in which the air that has passed through 31A is distributed to the dehumidified air passage 90 and the state in which the air that has passed through the second adsorption element 31B is distributed to the humidified air passage 80 is switched.

  As shown in FIG. 2, the flow path switching unit 4 includes a first inflow space 3 </ b> A into which air that has passed through the first adsorption element 31 </ b> A flows by a partition plate 40 disposed on the downstream side of the adsorption module 3. It is divided into a second inflow space 3B into which air that has passed through the second adsorption element 31B flows.

  As shown in FIG. 2, the downstream side of the partition plate 40 is divided into a humidified air passage 80 connected to the humidified air outlet 8 and a dehumidified air passage 90 connected to the dehumidified air outlet 9 by a partition wall 11 formed integrally with the casing 1. The section of the humidified air passage 80 is smaller than that of the dehumidified air 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 unit 4 includes a plurality of flow path switching doors 6 and a shaft 60. The flow path switching door 6 is disposed between the partition plate 40 and the partition wall 11. The shaft 60 is integrally provided with the flow path switching door 6. The shaft 60 is rotatably provided along the width direction X of the casing 1.

  The shaft 60 is provided with four flow path switching doors 6, two humidifying side doors 61 a and 61 b and two dehumidifying side doors 62 a and 62 b. In order to reduce the rotation range θ (about 60 degrees in this embodiment) of the flow path switching door 6, two humidifying doors 61a and 61b and two dehumidifying doors 62a and 62b are provided. The humidifying side doors 61a and 61b communicate with the humidified air passage 80 and the first inflow space 3A and close the humidified air passage 80 and the second inflow space 3B according to the angular position thereof. Conversely, the humidified air passage 80 and the second inflow space 3B are communicated, and the humidified air passage 80 and the first inflow space 3A are closed. Similarly to the humidifying doors 61a and 61b, the dehumidifying doors 62a and 62b communicate the dehumidifying air passage 90 and the first inflow space 3A in accordance with the angular positions thereof, and the dehumidifying air passage 90 and the second inflow space 3B. On the contrary, the dehumidifying air passage 90 and the second inflow space 3B are connected to each other, and the dehumidifying air passage 90 and the first inflow space 3A are closed.

  The door areas of the humidifying doors 61a and 61b and the dehumidifying doors 62a and 62b are substantially proportional to the passage cross-sectional areas of both flow passages 80 and 90, and the dehumidifying doors 62a and 62b are large. Is getting smaller. Further, a lever plate 63 for rotating the flow path switching door 6 is provided at one end side of the shaft 60, and the lever plate 63 is configured to protrude to the outside of the casing 1. On the outer surface of the casing 1, an actuator 7 such as a servo motor that is connected to the end of the lever plate 63 and switches the flow path switching door 6 is disposed.

  Next, the operation of the flow path switching unit 4 will be described. 6 and 7 are diagrams for explaining the mechanism of channel switching, wherein (a) is a cross-sectional view taken along the line aa in FIG. 1, and (b) is a cross-sectional view taken along the line bb in FIG. FIG. 6 shows a state in which the flow path switching unit 4 is at the first flow path switching position. FIG. 7 shows a state where the flow path switching unit 4 is at the second flow path switching position.

  When the flow path switching unit 4 is in the first flow path switching position, the humidifying side doors 61a and 61b close the humidified air passage 80 and the first inflow space 3A, and the humidified air passage 80 and the second inflow space. This is a state where 3B is communicated. The dehumidifying side doors 62a and 62b communicate with the dehumidifying air passage 90 and the first inflow space 3A and close the dehumidifying air passage 90 and the second inflow space 3B.

  Therefore, as shown in FIG. 6A, on the humidified air outlet 8 side, the humidified air that has flowed out to the second inflow space 3B flows out to the humidified air outlet 8 as it is, and the dehumidified air that has flowed out to the first inflow space 3A is Since the flow path to the humidification air outlet 8 is closed by the humidification side door 61b, it flows in the first inflow space 3A to the other side in the width direction X (the front side in FIG. 6) and moves to the dehumidification air passage 90 side. From there, it flows out to the dehumidifying air outlet 9.

  Similarly, on the side of the dehumidifying air outlet 9 in FIG. 6B, the dehumidifying air flowing out to the first inflow space 3A directly flows out to the dehumidifying air outlet 9, and the humidified air flowing out to 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 in the width direction X side (the back side in FIG. 6) and moves to the humidified air passage 80 side. From there, it flows out to the humidified air outlet 8.

  In a state where the flow path switching unit 4 is at the second flow path switching position, it is in a state opposite to the first flow path switching position described above, and the humidifying side doors 61a and 61b are connected to the humidified air passage 80 and the first flow switching position. This is a state in which the 1 inflow space 3A is communicated and the humidified air passage 80 and the second inflow space 3B are closed. The dehumidifying side doors 62a and 62b are in a state of closing the dehumidifying air passage 90 and the first inflow space 3A and communicating the dehumidifying air passage 90 and the second inflow space 3B.

  Therefore, on the side of the humidified air outlet 8 in FIG. 7A, 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 is 8 is closed by the humidifying side door 61a, so that it flows in the second inflow space 3B to the other side in the width direction X (the front side in FIG. 7) and moves to the dehumidifying air passage 90 side. It flows out to the dehumidifying wind outlet 9.

  Similarly, on the side of the dehumidifying air outlet 9 in FIG. 7B, 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 blocked by the dehumidifying side door 62a, it flows in the first inflow space 3A in the width direction X one side (the back side of the drawing in FIG. 7) and moves to the humidified air passage 80 side. From there, it flows out to the humidified air outlet 8.

  The control device (not shown) is a control means, and controls the blower 2, controls the current of the Peltier element 30 in the adsorption module 3, and controls the actuator 7 in the flow path switching unit 4. The control device is realized by a microcomputer, for example.

  The control device controls the flow path switching door 6 to rotate according to the reversal of the current of the Peltier element 30, and the destination of each air processed by the adsorption module 3 is one of the humidified air outlet 8 From the dehumidifying air outlet 9 to the humidifying 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 each plate surface portion 30a, 30b of the Peltier element 30 is reversed in high and low, and usually after the reversal of the current. This is a period until a time of about 30 seconds to 60 seconds elapses. The control device can generate the dehumidified air and the humidified air more efficiently by operating the flow path switching door 6 and switching the destination after a while after the current reversal.

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

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

  Air dehumidified after passing through the first adsorption element 31A of the adsorption module 3 flows out into the first inflow space 3A, and air humidified through the second adsorption element 31B outflows into the second inflow space 3B. Then, the humidified air is directed to the humidified air passage 80 and blown out from the humidified air outlet 8 by the flow path switching door 6, and the dehumidified air is directed to the dehumidified air passage 90 and blown out from the dehumidified air outlet 9. The

  In this case, since the second adsorption element 31B is heated by the other plate surface portion 30b of the Peltier element 30, the heat is located in the other thickness direction (downward in FIG. 1) via the outer wall 1a below the casing 1. It is transmitted to one part in the length direction Y of the heat transfer section 25 that performs. Thereafter, heat is transferred from one portion in the length direction Y of the heat transfer section 25 toward the other in the length direction Y, and is transferred to the other portion in the length direction Y of the heat transfer section 25, in other words, the humidified air outlet 8. Heat is transmitted to the portion of the casing 1 that forms the air passage 80.

  Next, in the adsorption 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, one plate surface portion 30a functions as a heat dissipation portion, and the other plate surface portion 30b functions as a heat absorption portion. Then, by switching the functions of the plate surface portions 30a and 30b of the Peltier element 30, the adsorption operation and desorption operation of the adsorbent are reversed in the adsorption elements 31A and 31B, respectively.

  Therefore, the first adsorbing element 31A desorbs the water vapor that has been adsorbed until the fin 33 that has been cooled is heated. The second adsorption element 31B starts adsorption of water vapor when the heated fins 33 are 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 second inflow space 3B, and the dehumidified air flows out to the first inflow space 3A.

  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. Therefore, for example, the flow path switching door 6 is switched from the state shown in FIG. 6 to the state shown in FIG. For this reason, the air humidified by passing through the first adsorption element 31A of the adsorption module 3 flows out into the first inflow space 3A, and the air dehumidified through the second adsorption element 31B is in the second inflow space. 3B, the air that has been humidified by the flow path switching door 6 is directed to the humidified air passage 80 and blown out from the humidified air outlet 8, and the dehumidified air is directed to the dehumidified air passage 90 and is supplied to the dehumidified air outlet. 9 is blown out.

  The dehumidifying / humidifying device 100 reverses the adsorption operation and desorption operation at a certain timing in the adsorption module 3 as described above, and in accordance with this, the dehumidifying / humidifying device 100 flows through the blow-off flow path between the dehumidified air and the humidified air. Switching is performed by the road 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. Then, the dehumidified air is used for anti-fogging of the window glass, and the humidified air is used for improving comfort.

  In this case, since the first adsorption element 31A is heated by one plate surface portion 30a of the Peltier element 30, the heat is located on one side in the thickness direction (upward in FIG. 1) via the outer wall 1a above the casing 1. It is transmitted to one part in the length direction Y of the heat transfer section 25 that performs. Thereafter, heat is transferred from one portion in the length direction Y of the heat transfer section 25 toward the other in the length direction Y, and the other portion in the length direction Y of the heat transfer section 25, the casing 1 forming the humidified air passage 80. Heat is transmitted to the part.

  As described above, in the dehumidifying / humidifying device 100 of this embodiment, the humidified air humidified by the adsorption module 3 passes through the humidified air passage 80 by the flow path switching unit 4. Since the casing 1 that forms the humidified air passage 80 is thermally connected to the Peltier element 30 by the heat transfer section 25, the heat of the Peltier element 30 is transmitted to the portion of the casing 1 that forms the humidified air passage 80. . As a result, the portion of the casing 1 that forms the humidified air passage 80 is heated. Therefore, even if the humidified air passage 80 is condensed, the dew condensation can be evaporated by operating the dehumidifying / humidifying device 100. . Therefore, the generation of a strange odor due to condensation of the humidified air passage 80 and the growth of fungi can be suppressed. Further, since the humidified air passage 80 is heated using the amount of heat generated by the Peltier element 30 without newly providing a heating means, the dehumidifying / humidifying device 100 of the present embodiment is realized with a simple configuration in which the heat transfer section 25 is provided. can do.

  Moreover, in this Embodiment, since the heat-transfer part 25 is provided in the outer wall part 1a of the casing 1 which forms the humidified air channel | path 80, the humidified air channel | path 80 can be heated from the outer wall part 1a. Thereby, even if it is an existing dehumidifying / humidifying device, the dehumidifying / humidifying device 100 of the present embodiment can be easily realized by providing the heat transfer section 25 from the outside.

  Further, in the present embodiment, one end portion in the length direction Y of the heat transfer section 25 is configured to reach a region where the adsorption module 3 is projected in the thickness direction Z. Thus, the generated heat can be efficiently transmitted to the humidifying air passage 80 to the adsorption module 3.

  In the present embodiment, the other end in the length direction Y of the heat transfer section 25 is located at a portion of the casing that forms the humidified air outlet 8. Therefore, since the humidified air outlet 8 which is a protruding portion where moisture is scattered into the vehicle interior is also reliably heated, it is possible to prevent moisture based on condensation from being scattered from the humidified air outlet 8.

  In the present embodiment, the humidified air passage 80 is heated using the Peltier element 30. The Peltier element 30 is a constituent element necessary for humidification and dehumidification. Conventionally, the Peltier element 30 radiates heat to the outside air without using any heat generated by the Peltier element 30 itself. Then, since the heat that has been discarded is used, heating the humidified air passage 80 does not consume new power.

  In the present embodiment, a pair of fixed adsorbing elements 31A and 31B provided with adsorbents are directly disposed on the plate surface portions 30a and 30b functioning as the heat absorbing and radiating portions of the Peltier element 30, respectively. 3 is configured. The adsorption module 3 functionally replaces the heat absorption part and the heat dissipation part by reversing the current flowing to the Peltier element 30, switches the cooling and heating for the adsorption elements 31A and 31B, and reverses the adsorption operation and the desorption operation. The 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 reverse of the adsorption operation and the desorption operation.

  Accordingly, the dehumidifying / humidifying device 100 does not need to be provided with a rotation driving unit as in the adsorption rotor system, and the adsorption elements 31A and 31B are directly arranged on the Peltier element 30 to heat and cool the adsorption elements 31A and 31B. Since the thermal conductivity between the Peltier element 30 and the adsorption element 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.

  Further, the flow path switching unit 4 can switch the destination of each air by rotating by the actuator 7. Therefore, since the channel switching can be realized with a simple configuration, the channel switching unit 4 can be miniaturized.

Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 8 is a plan sectional view showing a dehumidifying / humidifying device 100A of the second embodiment. FIG. 9 is a side sectional view of the dehumidifying / humidifying device 100A.

  In the present embodiment, the heat transfer section 25A is provided on the inner wall portion 1b of the casing 1 that forms the humidified air passage 80, so that the humidified air passage 80 can be heated from the inner wall portion 1b. As a result, the portion of the humidified air passage 80 where condensation may occur can be directly heated, so that condensation can be reliably prevented.

  In the present embodiment, since the heat transfer section 25A is provided on the inner wall portion 1b, the heat transmitted to the heat transfer section 25A is blocked from the outside air by the casing 1 made of resin, so that the heat of the heat transfer section 25A is not sufficient. It does not radiate heat to the outside as desired. Therefore, the heat transfer section 25 </ b> A can efficiently transfer the heat of the Peltier element 30 to the portion of the casing that forms the humidified air passage 80. Further, since the appearance is formed by the casing 1 made of resin, it is possible to prevent the outer wall of the casing 1 from condensing.

The dehumidifying / humidifying device 100B of the present embodiment is different from the dehumidifying / humidifying device 100 of the first embodiment in the configuration of the heat transfer section 25B.

  At least a part of the casing 1 is formed by the heat transfer section 25C. Therefore, the heat transfer section 25B forming the humidified air passage 80 is a rectangular tube shape, and the humidified air passes through the inside. Further, the heat transfer section 25 </ b> B is provided so as to function as the casing 1 on a part of both surface portions in the thickness direction Z of the casing 1. One end portion in the length direction Y of the heat transfer section 25B is configured to reach a region where the adsorption module 3 is projected in the thickness direction Z. The heat transfer section 25 </ b> B is provided so as to cover the entire adsorption module 3 when viewed from the thickness direction Z. The heat transfer unit 25 </ b> B is provided so as not to contact the adsorption module 3.

  In the present embodiment, since the heat transfer section 25B is configured integrally with the casing 1 that forms the humidified air passage 80, the portion of the humidified air passage 80 where condensation may occur can be directly heated, and the dew condensation is generated. It can be surely prevented.

One door and one dehumidifying side door may be formed at positions facing each other, and the doors may be rotated 180 degrees so that the positions where the doors are closed are switched. Although the rotation range of the door becomes large, the shape of the door can be simplified.

  The configuration of the flow path switching unit 4 is not limited to the configuration of rotating the door described above. As another mechanism for switching the air flow path, for example, two flexible pipes are moved and connected to each other.
