Description

  The present invention relates to a dehumidifying / humidifying device that takes in air and blows out dehumidified air and humidified air.

  As a first conventional dehumidifying / humidifying device, there is an apparatus having a structure in which a heat absorbing / dissipating plate is attached to both sides of a thermoelectric conversion element and a moisture absorbing material is attached to one side. In such a dehumidifying / humidifying device, the polarity of the DC voltage applied to the thermoelectric conversion element is switched, the hygroscopic material is cooled during the hygroscopic operation, and the hygroscopic material is warmed during the dehumidifying operation (for example, Patent Document 1). reference).

  As a second conventional dehumidifying / humidifying device, there is a device configured to accommodate a blower, an adsorption module, and a flow path switching device in a casing. The adsorption module is configured by directly arranging the first adsorption element and the second adsorption element on each surface of the Peltier element. The flow path switching device can turn the air passing through the first adsorbing element and the air passing through the second adsorbing element to the first air outlet and the second air outlet, and can switch the destination of the air. It is configured.

In the adsorption module, the current of the Peltier element is reversed to exchange the heat absorption part and the heat dissipation part of the Peltier element, and the destination of each air is switched in the flow path switching device (see, for example, Patent Document 2).

  In the first prior art described above, the heat absorbing / dissipating plate is uniformly heated by the thermoelectric conversion element during humidification. However, the temperature of the heat absorbing / dissipating plate generates a thermal gradient in which the temperature on the windward side is low in the ventilation direction and gradually increases toward the leeward side due to the wind flow with respect to the heat absorbing / dissipating plate. In other words, the heat absorbing / dissipating plate does not have a uniform temperature, and a temperature distribution occurs in the heat absorbing / dissipating plate. Since the moisture absorption amount of water that can hold water varies depending on the temperature, a distribution occurs in the water discharge amount of the moisture absorption agent. Therefore, there is a problem that the performance of the adsorbent is not fully exhibited because the humidifying performance is partially different in the heat absorbing / dissipating plate. There are similar problems during dehumidification.

  Also in the second prior art described above, since the temperature distribution is similarly generated in each surface of the Peltier element, there is a problem that the performance of the adsorbent cannot be fully exhibited and the humidification performance and dehumidification performance are not stable.

  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 making the dehumidifying / humidifying performance of the adsorbing element uniform in the air conditioning means.

  The present invention employs the following technical means in order to achieve the aforementioned object.

A flow path switching means (4) for guiding the air humidified by the air conditioning means to the humidified air passage and guiding the dehumidified air to the dehumidified air passage;
A dehumidifying / humidifying device comprising temperature adjusting means (33) for making the temperature of the adsorbing portion uniform with respect to a width direction substantially orthogonal to a flow direction of air passing through the heat exchanging portion.

  According to the first aspect of the present invention, the temperature adjusting means for making the temperature of the suction portion uniform in the width direction is provided. Such temperature adjusting means makes the temperature uniform in the width direction of the adsorbing portion, so that temperature deviation can be eliminated. Since the adsorption unit adsorbs and releases moisture based on the temperature of the heat exchange unit, the amount of moisture to be adsorbed and released can be made uniform by making the temperature uniform. As a result, the dehumidifying / humidifying performance can be exhibited uniformly in the adsorption portion, and the dehumidifying / humidifying performance can be stabilized. Therefore, by controlling the air-conditioning means, it is possible to generate dehumidified air and humidified air in a desired state, and the convenience of the dehumidifying / humidifying device can be improved.

  Further, in the invention according to claim 2, the temperature adjusting means has a portion with a large wind speed and a small remaining wind speed based on the wind speed distribution of the air blown by the air blowing means upstream of the heat exchange section in the main casing. The portion is characterized in that the pressure loss at the portion where the wind speed is high is made larger than the portion where the wind speed is low.

  According to the second aspect of the present invention, the temperature adjusting means makes the pressure loss of the portion where the wind speed of the blown air is large larger than the portion where the wind speed is small. The air volume in a small part can be increased. Thereby, the distribution of the airflow passing through the adsorption portion can be made uniform. Accordingly, since the heat transfer amounts between the adsorption part and the air are substantially equal, the temperature can be made uniform in the width direction of the adsorption part. As a result, it is possible to achieve the above-described effect due to the uniform temperature of the adsorption portion.

  Further, the invention according to claim 3 is characterized in that the temperature adjusting means is provided so as to equalize the wind speed distribution on the upstream side of the heat exchange section.

  According to the third aspect of the present invention, the temperature adjusting means equalizes the wind speed distribution in the adsorption section. Therefore, when there are a plurality of air flow paths passing through the adsorption section, the cross-sectional areas of the flow paths are made equal to each other. Thus, the air volume distribution can be made uniform. As a result, it is possible to achieve the effect of making the above-described air volume distribution uniform.

  Furthermore, the invention according to claim 4 is characterized in that the heating unit heats the upstream side of the heat exchange unit so that the temperature is higher than the downstream side.

  According to invention of Claim 4, a heating part heats the upstream of a heat exchange part so that temperature may become higher than a downstream. The downstream side of the adsorption unit provided in the heat exchange unit is heated by heat conduction from the upstream side of the heat exchange unit and heat transfer of air heated by heat exchange on the upstream side. The temperature in the flow direction can be made uniform. In other words, it is possible to make the temperature of the adsorbing portion uniform in the flow direction by heating the upstream side more strongly than in heating the adsorbing portion uniformly in the flow direction. As a result, it is possible to achieve the above-described effect due to the uniform temperature of the adsorption portion.

Further, in the invention according to claim 5, the temperature adjusting means is a plurality of fins provided in the heat exchange part, extending along the air flow direction, and formed at intervals in the width direction,

  According to the fifth aspect of the present invention, the pitch of the plurality of fins is such that the portion where the wind speed is high is smaller than the portion where the wind speed is low, so the air volume in the portion where the wind speed is high is reduced and the air volume is increased in the portion where the wind speed is low. be able to. As a result, the distribution of the airflow passing through the adsorption portion can be made uniform, so that the effect of making the distribution of the airflow in the adsorption portion described above uniform can be achieved.

Further, in the invention described in claim 6, the temperature adjusting means is a plurality of fins provided in the heat exchange section, extending along the air flow direction, and spaced apart in the width direction.
The length dimension of the plurality of fins in the flow direction is characterized in that a portion where the wind speed is high is larger than a portion where the wind speed is low.

  According to the sixth aspect of the present invention, the length dimension in the flow direction of the plurality of fins is such that the portion where the wind speed is high is larger than the portion where the wind speed is low, so that the pressure loss of the portion where the wind speed is high is large and the portion where the wind speed is low The pressure loss can be reduced. As a result, the distribution of the airflow passing through the adsorption portion can be made uniform, so that the effect of making the distribution of the airflow in the adsorption portion described above uniform can be achieved.

Further, in the invention according to claim 7, the temperature adjusting means is a plurality of fins provided in the heat exchanging portion, extending along the air flow direction, and spaced apart in the width direction.
The thickness dimension of the plurality of fins is characterized in that a portion where the wind speed is high is larger than a portion where the wind speed is low.

  According to the seventh aspect of the present invention, the thickness dimension of the plurality of fins is such that the portion where the wind speed is high is larger than the portion where the wind speed is low, so that the pressure loss in the portion where the wind speed is high is increased and the pressure in the portion where the wind speed is low. Loss can be reduced. As a result, the distribution of the airflow passing through the adsorption portion can be made uniform, so that the effect of making the distribution of the airflow in the adsorption portion described above uniform can be achieved.

The adsorption portion is provided on the surface of the plurality of fins,
The thickness dimension of the adsorption part is characterized in that a portion with a high wind speed is larger than a portion with a low wind speed.

  According to the invention described in claim 8, since the thickness portion of the adsorption portion is larger in the portion where the wind speed is higher than the portion where the wind speed is low, the pressure loss in the portion where the wind speed is high is increased, and the pressure loss in the portion where the wind speed is low. Can be small. As a result, the distribution of the airflow passing through the adsorption portion can be made uniform, so that the effect of making the distribution of the airflow in the adsorption portion described above uniform can be achieved.

Furthermore, in the invention described in claim 9, the air blowing means is
A spiral scroll casing (20) in which an inlet (23) and an outlet (24) are formed;
A multiblade fan (21) provided in the scroll casing,

  Hereinafter, a plurality of embodiments for carrying out the present invention will be described with reference to the drawings. Portions corresponding to the matters described in the preceding forms in each embodiment are denoted by the same reference numerals, and overlapping description may be omitted. When only a part of the configuration is described, the other parts of the configuration are the same as those described in the preceding section. 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 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. An opening 10 that opens outward is formed at one end of the casing 1 in the longitudinal direction Y in order to send air to the main passage 26.

  The opening 10 is formed on the other side (the lower side in FIG. 1) in the width direction X of the casing 1. The opening 10 is formed at an end portion that is tapered toward one side in the length direction Y (rightward in FIG. 1). Therefore, the wall portion 1a on the one side in the width direction X of the casing 1 for forming the opening 10 is inclined so as to go to the one side in the length direction Y as it goes to the other side in the width direction X. The wall 1b on the other side in the width direction X of the casing 1 for forming the opening 10 extends in the length direction Y.

  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 and the dehumidified air outlet 9 are defined by a partition wall 11 formed integrally with the casing 1. In this embodiment, the humidified air outlet 8 is formed smaller than the humidified air outlet 9. Yes. 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.

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

  Since the opening 10 is formed on the other side in the width direction X in the casing 1 (the lower side in FIG. 1), the air blown from the outlet 24 of the blower 2 flows from the other side in the width direction X of the main passage 26. Therefore, the wind speed distribution on the upstream side of the suction module 3 in the main passage 26 is such that the portion where the blower outlet 24 faces the other in the length direction Y is a portion where the wind speed is high, and the wall portion 1a on the one side in the width direction X is the length direction Y. The other part is the part where the wind speed is low.

  Furthermore, the air rectified in the radial direction and the circumferential direction by the spiral flow path of the scroll casing 20 is not uniform in the wind speed distribution, and as shown by arrows in FIG. The lower wind direction in FIG. 1 has the highest wind speed, and the wind speed gradually decreases toward the one side in the width direction X. In the main passage 26 on the one side in the width direction X from the end portion on the one side in the width direction X of the opening 10, air is guided by the wall portion 1 a on the one side in the width direction X, so that the wind speed is further reduced.

  Next, the adsorption module 3 will be described with reference to FIG. FIG. 3 is an enlarged perspective view showing a part of 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 heating unit, and heats the first adsorption element 31A and the 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. As shown in FIG. 1, the Peltier element 30 is formed in a substantially right triangular plate shape. The posture of the Peltier element 30 extends in the length direction Y toward the other side as the hypotenuse goes in the other direction in the width direction X, the one side extending in the length direction Y is short, and the one side extending in the width direction X is long.

  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. The length dimension in the length direction Y of the Peltier element 30 is shorter than the length dimension in the length direction Y of each adsorption | suction element 31A, 31B, for example, is set to about 1/2. The Peltier element 30 is disposed closer to the upstream side than the center in the length direction Y of each adsorption element 31A, 31B. The upstream end position in the length direction Y of the Peltier element 30 and the upstream end position in the length direction Y of the adsorption elements 31A and 31B are substantially the same position. Therefore, the Peltier element 30 heats the upstream side of each adsorption element 31A, 31B so that the temperature is higher than the downstream side.

  A heat insulating member 34 is provided in a space downstream of the Peltier element 30 and between the adsorption elements 31A and 31B. The heat insulating member 34 insulates the first adsorption element 31A and the second adsorption element 31B. The heat insulating member 34 integrally joins aluminum square tubes having the same shape as the Peltier element 30 and uses an air layer in the square tubes for heat insulation.

  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 board | substrate 32 and the fin 33 are heat exchange parts, Comprising: It forms with the metal which is excellent in heat 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. Accordingly, the substrate 32 has a substantially right triangular plate shape.

  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 fin pitch is equal to each other, and the thickness dimensions of the fins are also equal to each other. Accordingly, the gaps between the fins are also equal to each other.

  The fins 33 have a function as a heat exchange unit that exchanges heat with the air blown by the blower 2, and also have a function as a temperature adjusting unit that equalizes the temperature of the adsorbent to be applied. Each fin 33 is provided so that the pressure loss of the portion where the wind speed of the air blown by the blower 2 is large is larger than the portion where the wind speed is small. The dimension of the fin 33 in the length direction Y is set so that the portion where the wind speed is high is larger than the portion where the wind speed is low. Therefore, according to the wind speed distribution shown in FIG. 1, the length dimension of the fin 33 is set to be larger on the other side in the width direction X (lower side in FIG. 1). The length dimension of 33 gradually decreases. Further, the upstream end portion (the right side in FIG. 1) of each fin 33 is set so as to be substantially in the same position in the length direction Y. Therefore, the downstream end portions (left side in FIG. 1) of the fins 33 are located at different positions with respect to the length direction Y, and are gradually positioned on the upstream side toward the one side in the width direction X.

  The adsorbent is an adsorbing portion that adsorbs and releases moisture based on the temperatures of the substrate 32 and the fins 33. 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.

  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 one side (the back side of the drawing 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 into the first inflow space 3A directly flows out into the humidified air outlet 8, and the dehumidified air that has flowed out into 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

  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.

  As described above, in the dehumidifying / humidifying device 100 of the present embodiment, the plurality of fins 33 are provided as temperature adjusting means for equalizing the temperature of the adsorbent. The length dimension of each fin 33 is set so that the portion where the wind speed is high is larger than the portion where the wind speed is low. Since the pressure loss in the portion where the wind speed of the blown air is large is made larger than the portion where the wind speed is small, the air volume in the portion where the wind speed is high can be reduced, and the air volume in the portion where the wind speed is low can be increased. Thereby, the distribution of the air volume passing between the fins can be made uniform. Therefore, the heat transfer amount between the adsorbent applied to each fin and the air becomes substantially equal in the width direction X, so that the temperature can be made uniform in the width direction X.

  As described above, the temperature of the adsorbent is made uniform by the plurality of fins 33 functioning as temperature adjusting means, so that the temperature deviation in the adsorbent can be eliminated. Since the adsorbent adsorbs and releases moisture based on the temperature of the fins 33, the amount of moisture adsorbed and released can be made uniform by making the temperature uniform.

  For example, in the heated fin 33, the moisture release distribution in the plurality of fins 33 is made uniform in the adsorption elements 31A and 31B. Therefore, the moisture release time of the adsorbent becomes constant, and the timing of moisture depletion of the adsorbent can be synchronized. In other words, it is difficult for the adsorbent of a certain part to release moisture, but the adsorbent of the other part is less likely to have moisture that can be released.

  Similarly, in the fin 33 being cooled, the moisture adsorption distribution in the plurality of fins 33 is made uniform in the adsorption elements 31A and 31B. Therefore, the moisture adsorption time of the adsorbent becomes constant, and the timing of moisture saturation of the adsorbent can be synchronized. In other words, the adsorbent in a certain portion has absorbed moisture, but the adsorbent in other portions is less likely to absorb moisture.

  Thus, in the dehumidifying / humidifying device 100 of the present embodiment, the dehumidifying / humidifying performance can be exhibited uniformly in the adsorbent, and the dehumidifying / humidifying performance can be stabilized. Therefore, by controlling the Peltier element 30, it is possible to generate dehumidified air and humidified air in a desired state, and the convenience of the dehumidifying / humidifying device 100 can be improved.

  Further, since the temperature distribution is eliminated, the amount of heat is not wasted, and the power consumption in the Peltier element 30 can be reduced. Further, since the adsorbent is not overheated, the temperature of the humidified air can be lowered. Similarly, since the adsorbent is not supercooled, the temperature of the dehumidified air can be increased.

  Further, in the suction module 3, the length of the Peltier element 30 in the length direction Y (circulation direction) is formed shorter than the length of the fin 33 in the length direction Y, and the Peltier element 30 with respect to the fin 33. Is disposed at a position on the upstream side. Accordingly, the Peltier element 30 is heated so that the upstream side of the adsorption elements 31A and 31B has a higher temperature than the downstream side. The downstream side of the adsorbent provided in the adsorption elements 31A and 31B is heated by heat conduction from the upstream side of the adsorption elements 31A and 31B and heat transfer of air heated by heat exchange on the upstream side. The temperature in the direction Y can be made uniform. In other words, the temperature of the adsorbent can be made uniform with respect to the length direction Y by heating the upstream side more strongly than when the adsorbent is heated uniformly with respect to the length direction Y. As a result, sufficient adsorption / desorption action can be exerted on substantially the entire surface of the adsorption elements 31A and 31B without using wasted electric power.

  The length dimension of the Peltier element 30 is substantially half of the length dimension of the fin 33. According to this, it is possible to reduce the size of the Peltier element 30 to about half by making the heating capacity and the cooling capacity gradient to achieve efficient heating and cooling.

  The upstream end position of the Peltier element 30 and the upstream end position of the fin 33 are substantially the same. As a result, heating and cooling are performed from the upstream end of the fin 33, and efficient heating and cooling can be performed by raising the temperature to the required temperature from the vicinity of the upstream end as much as possible.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 8 is a plan sectional view showing a dehumidifying / humidifying device 100A of the second embodiment. The present embodiment is characterized in that the Peltier element 30 is extended in the portion of the heat insulating member 34 in the first embodiment, and the suction module 3 is arranged in the scroll casing 20.

  The air rectified in the radial direction and the circumferential direction by the spiral flow path formed by the scroll casing 20 has a non-uniform wind speed distribution, and the width direction X other side of the outlet 24 (the lower side in FIG. 1). The wind speed becomes larger. A fin 33 having a long length is provided in such a portion where the wind speed is high as in the first embodiment. Accordingly, the length dimension can be shortened as compared with the casing of the first embodiment. As a result, the dehumidifying / humidifying device 100A can be miniaturized. Further, the dehumidifying / humidifying device 100A of the present embodiment can achieve the same operations and effects with respect to the same configuration as that of the first embodiment.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIGS. FIG. 9 is a plan sectional view showing a dehumidifying / humidifying device 100B of the third embodiment. FIG. 10 is a cross-sectional view showing the adsorption module 3. The present embodiment is characterized in that the Peltier element 30 extends in the portion of the heat insulating member 34 in the first embodiment described above, and the configuration of the fins 33 is different.

  The thickness dimension of the plurality of fins 33 is set so that the portion where the wind speed is high is larger than the portion where the wind speed is low. Therefore, according to the wind speed distribution, the thickness dimension of the fin 33 is set so that the thickness dimension of the fin 33 becomes larger on the other side in the width direction X (the left side in FIG. 10). Gradually decreases.

  The fin pitch is equal to each other, and the length dimension of the fin 33 is also equal to each other. Accordingly, the gaps between the fins 33 are different from each other, the gap in the portion where the wind speed is high is small, and the gap in the portion where the wind speed is low is large. Therefore, the gap between the fins 33 is set to be smaller on the other side in the width direction X according to the wind speed distribution, and the gap between the fins 33 gradually increases toward the one side in the width direction X.

  As described above, in the present embodiment, the thickness dimension of the plurality of fins 33 is such that the portion where the wind speed is high is larger than the portion where the wind speed is low, so that the pressure loss in the portion where the wind speed is high is increased and the pressure loss in the portion where the wind speed is low. Can be reduced. As a result, the air volume distribution passing through the adsorbent 36 can be made uniform, so that the effect of making the air volume distribution uniform can be achieved as in the first embodiment. Further, the dehumidifying / humidifying device 100B of the present embodiment can achieve the same operations and effects with respect to the same configuration as that of the first embodiment.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG. FIG. 11 is a cross-sectional view showing the adsorption module 3C. The present embodiment is characterized in that the configurations of the fins 33 and the adsorbent 36 in the third embodiment described above are different.

  The thickness dimension of the adsorbent 36 provided on the surface of the plurality of fins 33 is set so that the portion where the wind speed is high is larger than the portion where the wind speed is low. Therefore, according to the wind speed distribution, the width direction X other side (left side in FIG. 11) is set so that the thickness dimension of the adsorbent 36 becomes larger, and the width direction X one side (right side in FIG. 11). , The thickness dimension of the adsorbent 36 gradually decreases. Accordingly, as shown in FIG. 11, the thickness dimension of the fin 33 is proportional to the thickness dimension of the adsorbent 36. Therefore, when the thickness dimension of the adsorbent 36 increases, the thickness dimension of the fin 33 increases.

  The fin pitch is equal to each other, and the length dimension of the fin 33 is also equal to each other. Accordingly, the gaps between the fins 33 are different from each other, the gap in the portion where the wind speed is high is small, and the gap in the portion where the wind speed is low is large. Therefore, as in the third embodiment described above, the gap between the fins 33 is set to be smaller on the other side in the width direction X according to the wind speed distribution, and between the fins 33 as it goes to one side in the width direction X. The gap of gradually increases.

  As described above, in the present embodiment, the thickness dimension of the adsorbent 36 provided on the plurality of fins 33 is such that the portion where the wind speed is high is larger than the portion where the wind speed is low. It is possible to reduce the pressure loss in the portion where is small. As a result, the distribution of the airflow passing through the adsorbent 36 can be made uniform, so that the effect of making the airflow distribution uniform can be achieved as in the third embodiment. Further, the dehumidifying / humidifying device of the present embodiment can achieve the same operations and effects with respect to the same configuration as that of the third embodiment described above.

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described with reference to FIG. FIG. 12 is a plan sectional view showing the dehumidifying / humidifying device 100 of the fifth embodiment. The present embodiment is characterized in that the Peltier element 30 extends in the portion of the heat insulating member 34 in the first embodiment described above, and the configuration of the fins 33 is different.

  The pitch of the plurality of fins 33 is set so that the portion where the wind speed is high is smaller than the portion where the wind speed is low. Therefore, the pitch of the fins 33 is set to be smaller on the other side in the width direction X (lower side in FIG. 12) according to the wind speed distribution, and the pitch of the fins 33 gradually increases toward the one side in the width direction X. growing.

  The thickness dimensions of the fins are equal to each other, and the length dimensions of the fins are also equal to each other. Accordingly, the gaps between the fins are different from each other, the gap at the portion where the wind speed is high is small, and the gap at the portion where the wind speed is low is large. Therefore, the gap between the fins 33 is set to be smaller on the other side in the width direction X according to the wind speed distribution, and the gap between the fins 33 gradually increases toward the one side in the width direction X.

  As described above, in the present embodiment, the pitch of the plurality of fins is such that the portion where the wind speed is high is smaller than the portion where the wind speed is low, so that the pressure loss in the portion where the wind speed is high is increased and the pressure loss in the portion where the wind speed is low is reduced. can do. As a result, the air volume distribution passing through the adsorbent can be made uniform, so that the effect of making the air volume distribution uniform can be achieved as in the first embodiment. Further, the dehumidifying / humidifying device of the present embodiment can achieve the same operations and effects with respect to the same configuration as that of the first embodiment.

(Other embodiments)
The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  In the first embodiment described above, the temperature adjusting means is realized by the plurality of fins 33. However, the temperature adjusting means is not limited to such a configuration, and the temperature adjusting means is realized by a guide plate that equalizes the wind speed distribution in the suction portion. Also good. For example, by providing the guide plate on the upstream side of the adsorption module 3 so as to distribute the air in the portion where the wind speed is high to the portion where the wind speed is low, the wind speed in the adsorption module 3 can be made uniform. By providing such a guide plate, it is possible to achieve the same operation and effect as when the air volume is made uniform.

  In the first embodiment described above, since the wind speed distribution varies linearly, the difference between the high wind speed portion and the low wind speed portion is not clear, but the pressure loss increases in proportion to the wind speed. As such, the length dimension of the fin 33 is selected, but the present invention is not limited to this. You may change the length dimension of the fin 33 in steps.

  Moreover, although a ventilation means is implement | achieved by the centrifugal blower, it is not restricted to a centrifugal blower, You may use the ventilation means with uniform wind speed.

It may be set.

  In the first embodiment, the Peltier element 30 is used as the heating unit. However, the heating unit is not limited to the Peltier element 30 and may be realized by a heater having only a heating function. When the heating means is a heater, there is no cooling function unlike the Peltier element 30, but the dehumidifying function can be achieved by natural cooling by air blowing.

  In the first embodiment described above, two humidification side doors 61a and 61b and two dehumidification side doors 62a and 62b are formed to reduce the rotation range of the flow path switching door 6. 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. It is also possible to use a mechanism that changes the connection destination, a mechanism that alternately opens and closes two shutters that operate synchronously by a link or the like, and changes the connection destination.

  Further, the fin 33 is limited to the shape of the fin 33 in each of the above-described embodiments as long as the size can be reduced, a large adsorption area can be secured, and a larger amount of powdery adsorbent can be held. Rather, various types of structures can be used. As the fin structure, for example, a corrugated type in which the opening shape of the ventilation cell is formed in a substantially triangular shape by a corrugated base sheet, a honeycomb type in which the opening shape of the ventilation cell is formed in a substantially hexagonal shape, and the ventilation cell A lattice-type structure in which the opening shape is formed in a square shape may be used.

  Further, the dehumidifying / humidifying device 100 may supply dehumidified air to the occupant side by changing the connection of the electric circuit in a situation where the outside air is at high humidity. Further, the dehumidifying / humidifying device 100 may be incorporated in an existing air conditioner.

However, it may be used in a normal room, and a predetermined space (for example, a bedroom) in a space (for example, a bedroom) that requires humidification. It may be used so that humidified air is blown out around the bedside of the bedding, and the dehumidified air is blown out to a space requiring dehumidification (for example, a window or wall where condensation easily occurs).
