Description

  The present invention relates to a vehicle dehumidifying / humidifying device that takes in air in a vehicle interior and blows out dehumidified air and humidified air. In particular, the present invention uses an adsorption / desorption function of an adsorbent, for example, in winter The present invention relates to a vehicle dehumidifying / humidifying device that supplies humidified air to a person's side and supplies dehumidified air to a window glass side or the like.

  As one of the air-conditioning techniques for the passenger compartment, various dehumidification / humidification techniques using the water vapor desorption function of the adsorbent have been studied in order to make the passenger compartment more comfortable and save energy. As such a technique, for example, an “air conditioner” disclosed in Patent Document 1 below is disclosed.

  This is because, for example, in summer, in order to supply dehumidified air to the side where people are present, it is divided into two air passages by a partition plate, and air passages each having an inlet and an exhaust at both ends. On the other hand, the heat exchange part and the moisture absorbing member (adsorption rotor) are sequentially arranged so as to straddle the two air passages.

  In this air conditioner, the air passing through one air passage is cooled by the heat exchange unit, the air passing through the other air passage is heated, and the moisture absorbing member is rotated or swung between the two air passages. And repeat the adsorption and desorption operations. And the air dehumidified through one ventilation path is supplied continuously indoors, and the air humidified through the other ventilation path is continuously discharged | emitted outside the room.

Further, the heat exchanging part is configured by disposing a heat conducting part in each of the heat absorbing part and the heat radiating part of the Peltier element, and cools the air in one air passage by the heat conducting part on the heat absorbing part side of the Peltier element, The air in the other air passage is heated by the heat conducting part on the heat radiating part side of the Peltier element, thereby supplying the moisture absorbing member with cold heat for promoting adsorption and warm heat necessary for desorption.
JP 2000-146220 A

  However, according to the configuration of Patent Document 1, the moisture absorbing member (adsorption rotor) is rotated or swung between the two air passages in order to repeat the adsorption and desorption operations. Therefore, a casing having a volume sufficient to accommodate the moisture absorbing member (suction rotor) and its driving mechanism is required, and there is a problem that it is difficult to reduce the size.

  In view of this, the inventors have provided a vehicle dehumidifying / humidifying device including a casing in which air blowing means, an adsorbent module, and a flow path switching unit are sequentially arranged along the air flow direction in order to reduce the volume of the casing. An application has been filed (Japanese Patent Application No. 2008-110567).

  In the dehumidifying / humidifying device in this patent application, a humidified air outlet for blowing humidified air and a dehumidified air outlet for blowing dehumidified air are provided at the most downstream portion of the casing. The adsorbent module includes a Peltier element having a pair of plate surfaces each functioning as a heat absorbing portion and a heat radiating portion, a first Peltier element that is disposed directly on each plate surface of the Peltier element, with an adsorbent held by a fin that can be ventilated. 1 adsorption element and 2nd adsorption element. In the first and second adsorption elements, a large number of fins are erected along the ventilation direction on a substrate that contacts each plate surface of the Peltier element.

  Then, one side of the first and second adsorption elements is cooled by the Peltier element, and the other side is heated by the Peltier element. The flow path switching unit can separately distribute the air that has passed through the first adsorbing element and the air that has passed through the second adsorbing element to the humidifying air outlet and the dehumidifying air outlet, and can flow the distribution destination. It can be switched by a road switching door.

  Further, the current flowing through the Peltier element is reversed to replace the heat absorption part and the heat dissipation part of the Peltier element, and the flow path switching unit switches the distribution destination of each air by the flow path switching door according to the reverse of the current. It is configured.

  In other words, the adsorption / desorption operation is reversed at a fixed timing by the adsorbent module, and the dehumidifying air is switched by switching the blowing flow path between the dehumidified air and the humidified air by the flow path switching door. The dehumidified air can be continuously blown out from the air blowing outlet, and the humidified air can be continuously blown out from the humidifying air blowing outlet.

  However, when the reversal of the polarity to the Peltier element is completed and the energization of the Peltier element is started before the flow path switching door is switched to the predetermined switching position, the humidified air is blown out from the humidified air outlet. The inconvenience was found that the air was blown out from the humidified air outlet, that is, from the dehumidified air outlet. That is, it has been found that the moisture trapped from the passenger compartment air by the fin adsorbent is wasted.

  Then, the objective of this invention is providing the dehumidification / humidification apparatus for vehicles which can aim at the improvement of the humidification performance of the humidified air which blows off toward a passenger | crew.

In order to achieve the above object, the following technical means are adopted. That is, in the first aspect of the present invention, the dehumidification that forms the flow path through which the air flows and that blows the humidified humidified air at the downstream end of the air flow and the dehumidified dehumidified air that blows the dehumidified dehumidified air. A casing (1) having an air outlet (9), a blower means (2) disposed at an end of the casing (1), for blowing air taken from the passenger compartment into the casing (1), and heat absorption And a Peltier element (30) having a pair of plate surfaces (30a, 30b) each functioning as a heat sink and a surface of the plate surfaces (30a, 30b) by holding an adsorbent on the surface of the fin (33) that can be ventilated. A first adsorbing element (31A) and a second adsorbing element (31B) arranged in each are provided so that air sent by the blowing means (2) can pass through each adsorbing element (31A, 31B). And air blowing means ( ), The adsorbent module (3) disposed inside the casing (1) between the humidified air outlet (8) and the dehumidified air outlet (9), and the adsorbent module (3) and the humidified air outlet (8 ) And the dehumidifying air outlet (9), and the first adsorbing element (31A) is disposed in the casing (1) between the humidifying air outlet (8) and the dehumidifying air outlet (9). A flow path switching unit (4) configured to be able to separately distribute the air that has passed through and the air that has passed through the second adsorption element (31B), and to switch the distribution destination by the flow path switching door (6); The casing (1) blows out the humidified air blown from the humidified air outlet (8) toward the occupant and directs the dehumidified air blown out from the dehumidified air outlet (9) toward a part other than the occupant. Addition for vehicles arranged to blow out In the device,
The direction of the current flowing in the Peltier element (30) is periodically reversed to switch the heat absorption part and the heat dissipation part of the Peltier element (30) alternately, and to switch between the heat absorption part and the heat dissipation part of the Peltier element (30). Correspondingly, the flow path switching door (6) is driven from the first flow path switching position to the second flow path switching position or from the second flow path switching position to the first flow path switching position. The distribution destinations of the humidified air and the dehumidified air are switched, and the flow path switching door (6) is changed from the first flow path switching position to the second flow path switching position or from the second flow path switching position. Until it is switched to one flow path switching position, the operation of the air blowing means (2) is stopped, or the air flow rate by the air blowing means (2) is controlled to a small value.

  According to this invention, since the air blowing means (2) is stopped or the amount of air blown by the air blowing means (2) is reduced, the air humidified by the first or second adsorption element (31A, 31B) is dehumidified. The trouble which blows off from a wind blower outlet (9) can be eliminated. Thereby, since the water | moisture content capture | acquired by the adsorbent of a fin (33) is not thrown away, the humidification capability of the humidification air blown off from a humidification air blower outlet (8) can be aimed at.

Until the position is switched, the energization to the Peltier element (30) is stopped. According to this invention, during operation of the flow path switching door (6), the humidified air does not leak from the dehumidified air outlet (9). Therefore, the humidified air is surely blown out from the humidified air outlet (8). Thereby, since the water | moisture content capture | acquired by the adsorbent of a fin (33) is not thrown away, the humidification capability of the humidification air blown off from a humidification air blower outlet (8) can be aimed at.

  In the invention according to claim 3, the flow path switching door (6) is switched from the first flow path switching position to the second flow path switching position, or from the second flow path switching position to the first flow path switching position. It is characterized in that energization to the Peltier element (30) is continued until the position is switched. According to the present invention, energization to the Peltier element (30) is started immediately after the direction of the current flowing through the Peltier element 30 is reversed, so that the rising characteristics of the humidified air and the dehumidified air can be improved.

The casing (1) may not be above the driver (Dr), and the space above the driver (Dr) is not reduced. In addition, the humidified air blowing ends (70a, 71a) can be configured at appropriate positions. Moreover, the ventilation sound (direct sound) of humidified air can be reduced by passing through the air ducts (70, 71). Furthermore, the humidified air can be reliably blown out directly to the driver (Dr).

  In the invention according to claim 5, the air duct (72) for sending the dehumidified air blown from the dehumidified air outlet (9) is disposed in the ceiling (50), and the dehumidified air is sent from the air duct (72) to the vehicle. It blows out toward the upper left and right parts of the front window glass (51). According to this invention, the dehumidified air can be used for anti-fogging of the front window glass (51). Further, when the direction of the current flowing through the Peltier element (30) is reversed, the humidified air is not blown out to the front window glass (51), so that the anti-fogging performance can be improved. Moreover, the ventilation sound (direct sound) of a dehumidification wind can be reduced through a ventilation duct (72).

  In the invention according to claim 6, the flow path switching unit (4) causes the first adsorbing element (31 </ b> A) to be moved by the first partition unit (40) disposed immediately downstream of the adsorbent module (3). It is divided into a first inflow space (3A) into which the air that has passed in and a second inflow space (3B) into which the air that has passed through the second adsorption element (31B) flows in, and the first partition portion (40) The downstream side is partitioned by the second partition (11) into a humidified air flow passage (80) that flows out to the humidified air outlet (8) and a dehumidified air flow passage (90) that flows out to the dehumidified air outlet (9).

(First embodiment)
Hereinafter, a vehicle dehumidifying / humidifying device according to a first embodiment of the present invention will be described with reference to FIGS. In the present embodiment, the dehumidifying / humidifying device is mounted in a vehicle interior of a vehicle, and is applied to a vehicle dehumidifying / humidifying device that takes in air in the vehicle interior and blows out dehumidified air and humidified air.

  This dehumidifying / humidifying device is used for supplying dehumidifying air for anti-fogging to the inner surface side of the vehicle front window glass and supplying humidified air to the passenger side, for example, in winter when the outside air is dry. In a situation where the outside air is at high humidity, dehumidified air may be supplied to the passenger by changing the connection of the electric circuit. Furthermore, although this dehumidifying / humidifying device can be incorporated into an existing air conditioner, as shown in the following embodiment, the entire device can be configured in a thin box shape and installed on a ceiling portion or the like in a vehicle interior. it can.

  FIG. 1 shows a schematic configuration of a vehicle dehumidifying / humidifying device according to the present embodiment, where FIG. 1 (a) is a plan view, and FIG. is there. First, the structure of a vehicle dehumidifying / humidifying device (hereinafter referred to as a dehumidifying / humidifying device) 100 will be described. As shown in FIG. 1A and FIG. 1B, the dehumidifying / humidifying device 100 of the present embodiment has a blower (blower unit) 2 at one end of a casing 1 molded with resin as a flow path through which air flows. Connected and configured.

  The blower 2 includes a flat scroll casing 20 formed of resin, a centrifugal multiblade fan (sirocco fan) 21 disposed therein, and a blower motor 22 that drives the fan 21. The vehicle interior air is sucked from a suction port 23 opened below the scroll casing 20 and blown out from the discharge port 24.

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

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

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

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

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

  As the fin 33, various structures can be used as long as the fin 33 can be reduced in size and a large adsorption area can be secured and a larger amount of powdery adsorbent can be held. As the structure of the fin 33, 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, a ventilation A lattice-type structure in which the opening shape of the cell is formed in a square shape may be used.

  In the present embodiment, the adsorbent satisfying the characteristics is preferably zeolite that can easily adsorb water vapor at a low humidity and can easily desorb at a low temperature. In the adsorbent module 3, the adsorbing elements 31 </ b> A and 31 </ b> B are heated by the Peltier element 30 without interposing air layers or other heat insulating elements on the plate surfaces 30 a and 30 b of the Peltier element 30. In addition, it may be arranged so that the cold heat is transmitted by heat conduction, and may be arranged through a heat conductive material such as silver paste or heat transfer grease.

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

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

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

  In the dehumidifying / humidifying device 100 of the present embodiment, in the adsorbent module 3, the adsorption operation and desorption operation of each adsorption element 31A, 31B are performed periodically, that is, every predetermined time (for example, about 5 to 10 minutes). Switch the current direction alternately with. Therefore, in this embodiment, since the humidified air is continuously blown out from the humidified air outlet 8 and the dehumidified air is continuously blown out from the dehumidified air outlet 9, as shown in FIG. The flow path switching unit 4 is disposed on the downstream side.

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

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

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

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

  As shown in FIGS. 3A and 3B, the flow path switching door 6 allows the shaft 60 to communicate with the humidified air flow passage 80 and one of the first inflow space 3A and the second inflow space 3B. The other side is closed, and the humidifying side doors 61a and 61b that can reverse the communication / blocking state, the dehumidifying air flow passage 90 and one of the first inflow space 3A and the second inflow space 3B are communicated to close the other. Dehumidifying side doors 62a and 62b that can reverse the state of communication / blocking are integrally provided.

  In addition, the door area of the humidification side doors 61a and 61b and the dehumidification side doors 62a and 62b is substantially proportional to the passage cross-sectional area of both the flow paths 80 and 90, and the dehumidification side doors 62a and 62b are large, and the humidification side door 61a. 61b is smaller.

  A lever plate 63 for rotating the flow path switching door 6 is provided on one end side of the shaft 60, and the casing 1 is divided into two vertically so that the lever plate 63 comes out of the casing 1. It is made to be pinched by. On the outer surface of the casing 1, an actuator 7 such as a servo motor that is connected to the end of the lever plate 63 and switches the flow path switching door 6 is disposed (see FIG. 1A).

  In the present embodiment, two humidification side doors 61a and 61b and two dehumidification side doors 62a and 62b are provided in order to reduce the rotation range of the flow path switching door 6 (about 60 degrees in the present embodiment). However, the humidifying side door and the dehumidifying side door are formed one by one at positions facing each other (for example, 61a and 62a or 61b and 62b in FIG. 3B), and each door is closed. It is good also as a structure rotated 180 degree | times so that a position may replace. Although the rotation range of the door becomes large, the shape of the door can be simplified.

  4 and 5 are diagrams for explaining a mechanism of channel switching. (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. It is. FIG. 4 shows the state of the first flow path switching position. By rotating the flow path switching door 6 to one side (the state of FIG. 4), the first inflow space 3A, the dehumidified air flow path 90, The second inflow space 3B and the humidified air flow passage 80 communicate with each other.

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

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

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

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

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

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

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

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

  In the present embodiment, the humidified air is blown out to the driver Dr and the dehumidified air is blown out to the space in the ceiling 50 through the air duct 70. For example, in the winter season when the outside air is dry, Humidified air is supplied to the driver Dr from a humidified air duct (blower duct) 71, and an anti-fog is provided from the dehumidified air duct (blower duct) 72 to the inner surface of the windshield (front window glass) 51 of the vehicle. You may comprise so that dehumidified air may be supplied.

  FIG. 6 is a partial side cross-sectional view of the vehicle showing a state in which the vehicle dehumidifying / humidifying device according to the modification of the present embodiment is disposed on the vehicle, and FIG. 7 is a partial plan view of the vehicle of FIG. As shown in FIGS. 6 and 7, a humidified air duct 71 is connected to the humidified air outlet 8. The humidified air duct 71 is routed in the space of the ceiling 50, and the blowing end 71 a is directed to the face of the driver (occupant) Dr seated in the driver seat 52.

  A dehumidifying air duct 72 is connected to the dehumidifying air outlet 9. The dehumidifying air duct 72 is routed in the space of the ceiling 50, and the blowing ends 72 a and 72 b are divided into two forks, each of which is directed to the upper left and right sides of the windshield 51.

  As shown in FIG. 1 (b), the driver Dr may be blown out directly from the casing 1 of the dehumidifying / humidifying device 100, but is blown out toward the driver Dr's face through the humidifying air duct 71. By adopting the configuration, the main body of the dehumidifying / humidifying device 100 may not be above the driver Dr, and the overhead space of the driver Dr is not narrowed.

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

  In addition, the dehumidified air can be used for anti-fogging of the windshield 51 by blowing out toward the upper left and right parts of the windshield 51 through the dehumidified air duct 72. Therefore, the front side of the instrument panel (dashboard), that is, the upper and left side portions of the windshield 51 which are difficult to clear with the defroster blown air of the vehicle air conditioner blown out from the lower end side of the windshield 51 is efficiently cleared. be able to. In addition, the dehumidifying air blowing ends 72a and 72b can be configured at appropriate positions. Furthermore, the blowing sound (direct sound) of the dehumidified air can be reduced through the dehumidified air duct 72.

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

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

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

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

  That is, the first adsorbing element 31 </ b> A desorbs the water vapor that has been adsorbed until the fin 33 that has been cooled is heated. On the other hand, said 2nd adsorption | suction element 31B starts adsorption | suction of water vapor | steam, when the fin 33 which was heated is cooled.

  As a result, the first adsorbing element 31A releases and vaporizes water vapor into the air passing therethrough, and the second adsorbing element 31B adsorbs and dehumidifies the water vapor in the air passing therethrough. Thereby, the humidified air flows out to the first inflow space 3A, and the dehumidified air flows out to the second inflow space 3B.

  When the voltage applied to the Peltier element 30, that is, the polarity is reversed, the flow path switching door 6 rotates from the first flow path switching position to the second flow path switching position to switch the flow path. . That is, the flow path switching door 6 is switched from, for example, the state shown in FIG. 4 to the state shown in FIG.

  For this reason, the air that has been humidified through the first adsorbing element 31A of the adsorbent module 3 flows out into the first inflow space 3A, and the air that has been dehumidified through the second adsorbing element 31B is 2 The air that flows out into the inflow space 3B and is humidified by the flow path switching door 6 is directed to the humidified air flow passage 80 and blown out from the humidified air outlet 8, and the dehumidified air is directed to the dehumidified air flow passage 90. Then, the air is blown out from the dehumidifying air outlet 9.

  In the dehumidifying / humidifying device 100 of the present embodiment, the adsorption / desorption operation is reversed at a certain timing in the adsorbent module 3 as described above, and according to this, the dehumidified air and the humidified air are The blowing channel is switched by the channel switching door 6.

  Thereby, the dehumidified air can be continuously blown out from the dehumidified air outlet 9, and the humidified air can be continuously blown out from the humidified air outlet 8. The humidified air is used for improving passenger comfort, and the dehumidified air is used for anti-fogging of the windshield 51.

  As described above, in the dehumidifying / humidifying device 100 according to the present embodiment, each of the plate surfaces 30a functioning as a heat absorbing part and a heat radiating part of the Peltier element 30 using the pair of fixed adsorbing elements 31A and 31B holding the adsorbent. The adsorbent module 3 is configured by being arranged directly on 30b.

  In the adsorbent module 3, the heat absorption part and the heat dissipation part are functionally switched by reversing the current flowing to the Peltier element 30, and the adsorption operation and the desorption operation are reversed by switching the cooling and heating for the adsorption elements 31A and 31B. The flow path switching door 6 is used to switch the destination of the air that has passed through the first adsorption element 31A and the air that has passed through the second adsorption element 31B according to the reversal of the adsorption operation and the desorption operation.

  By the way, in the dehumidifying / humidifying device 100 that performs such an operation, the polarity to the Peltier element 30 until the flow path switching door 6 is switched to a predetermined switching position (before the switching of the flow path switching door 6 is completed). Is completed, and energization to the Peltier element 30 is started, the humidified air is not blown out from the humidified air outlet 8, but is blown out from the humidified air outlet 8, for example, from the dehumidified air outlet 9. The problem of becoming.

  That is, the moisture trapped from the passenger compartment air by the adsorbent of the fin 33 may be blown out to other than the driver Dr. Therefore, there is a problem that the trapped water is discarded wastefully. Therefore, in the dehumidifying / humidifying device 100 of the present embodiment, when reversing the current flowing to the Peltier element 30, the energization of the Peltier element 30 is started after the flow path switching door 6 is switched to a predetermined switching position. It is configured.

  FIG. 8 is a flowchart showing the control processing of the control device in the present embodiment, and the dehumidifying / humidifying device 100 is controlled along this flowchart. When the operation of the dehumidifying / humidifying device 100 is started, first, in step S110, the flow path switching door 6 is switched to the first flow path switching position. In step S120, it is determined whether or not the flow path switching door 6 has been switched to the first flow path switching position.

  In addition, this step S120 determines, for example, whether or not a necessary time (for example, about 30 seconds to 60 seconds) for switching the flow path switching door 6 to the first flow path switching position has elapsed. Thus, it is a control process for determining whether or not the flow path switching door 6 has been switched to the first flow path switching position.

  When the determination in step S120 is “NO”, the process returns to step S110, and this operation is repeated until the flow path switching door 6 is switched to the first flow path switching position. If the determination in step S120 is “YES”, the process proceeds to step S130. In step S130, the Peltier element 30 is energized (positive polarity) so that dehumidification and humidification corresponding to the first flow path switching position are performed. That is, the desorption function is exhibited in the first adsorption element 31A, and the humidification function is exhibited in the second adsorption element 31B.

  In step S130, energization of the blower 2 is started at the same time. As a result, the air dehumidified by the first adsorbing element 31A is blown out from the dehumidified air outlet 9, and the air humidified by the second adsorbing element 31B is blown out from the humidified air outlet 8. In step S140, it is determined whether or not the operation in step S130 described above has been executed for a predetermined time (for example, about 5 to 10 minutes).

  If the determination in step S140 is “NO”, the process returns to step S130, and the operation of step S130 is continued until a predetermined time elapses. When the predetermined time has elapsed, the process proceeds to step S150. In step S150, energization to the Peltier element 30 and the blower 2 is interrupted (OFF), and the process proceeds to step S160.

  In step S160, the flow path switching door 6 is switched from the first flow path switching position to the second flow path switching position. In step S170, it is determined whether or not the flow path switching door 6 has been switched to the second flow path switching position. In step S170 as well, as in step S120, it is determined whether or not a necessary time (for example, about 30 to 60 seconds) for switching the flow path switching door 6 to the second flow path switching position has elapsed. By determining, it is determined whether or not the flow path switching door 6 has been switched to the second flow path switching position.

  When the determination in step S170 is “NO”, the process returns to step S160, and this operation is repeated until the flow path switching door 6 is switched to the second flow path switching position. If the determination in step S170 is “YES”, the process proceeds to step S180. In step S180, the Peltier element 30 is energized (polarity reversal) so that dehumidification and humidification corresponding to the second flow path switching position is performed. That is, the first adsorbing element 31A exhibits a humidifying function, and the second adsorbing element 31B exhibits a dehumidifying function.

  In step S180, energization of the blower 2 is started at the same time. As a result, the air humidified by the first adsorption element 31A is blown out from the humidified air outlet 8, and the air dehumidified by the second adsorption element 31B is blown out from the dehumidified air outlet 9. In step S190, it is determined whether or not the operation of step S180 described above has been executed for a predetermined time (for example, about 5 to 10 minutes).

  If the determination in step S190 is “NO”, the process returns to step S180, and the operation of step S180 is continuously executed until a predetermined time has elapsed. And when predetermined time passes, it progresses to step S200. In step S200, energization to the Peltier element 30 and the blower 2 is interrupted (OFF), the process returns to step S110, and the operations of steps S110 to S200 described above are repeated.

  By repeating the operation of FIG. 8, the dehumidified air can be continuously blown out from the dehumidified air outlet 9 and the humidified air can be continuously blown out from the humidified air outlet 8. The humidified air is used for improving passenger comfort, and the dehumidified air is used for anti-fogging of the windshield.

  Further, the adsorption elements 31A and 31B are directly arranged on the Peltier element 30, and since the thermal conductivity between the Peltier element 30 and the adsorption element when heating / cooling the adsorption elements 31A and 31B is high, the adsorption element 31A, 31B and the Peltier element 30 can be further reduced in size. As a result, the apparatus configuration can be simplified and the entire apparatus can be further reduced in size.

  Further, the amount of humidified air blown from the humidifying outlet 8 is reduced with respect to the amount of dehumidified air blown from the dehumidifying outlet 9. According to this, a large amount of moisture can be adsorbed and captured even from dry interior air in winter or the like, and the captured moisture is added to the air on the humidification side with a reduced air flow rate and blown out as humidified air Thus, the humidification performance (relative humidity) of the humidified air can be improved.

  Further, as described above, when the current flowing through the Peltier element 30 is reversed, the humidified air is blown out from the humidified air outlet 8 and dehumidified after the flow path switching door 6 is switched to the predetermined switching position. Since the air is blown out from the dehumidified air outlet 9, the air humidified by the first or second adsorption element 31 </ b> A, 31 </ b> B is not blown out from the dehumidified air outlet 9. Therefore, the humidification ability of the humidified air blown out from the humidified air outlet 8 can be improved.

  Specifically, during the operation of the flow path switching door 6 that switches the flow path according to the reversal of the current to the Peltier element 30, the blower 2 is stopped (OFF) and the energization to the Peltier element 30 is stopped. By being turned off, the humidified air is not blown out from the humidified air outlet 8, that is, from the dehumidified air outlet 9. Thereby, since the water | moisture content capture | acquired by the adsorbent of the fin 33 is not thrown away wastefully, the humidification capability of the humidification air which blows off from the humidification air blower outlet 8 can be aimed at.

  Further, the adsorbent module 3 starts energization to the Peltier element 30 after the flow path switching door 6 is switched to a predetermined switching position, so that the humidified air is surely blown out from the humidified air outlet 8. The Thereby, the humidification capability of humidified air can be improved.

(Second Embodiment)

Although configured to be switched, the flow path switching door 6 may be switched by stopping (OFF) the blower 2 and energizing (ON) the Peltier element 30.

  FIG. 9 is a flowchart showing the control processing of the control device in the present embodiment. In the flowchart of the present embodiment, the same reference numerals are given to the same control processing configuration as in the first embodiment described above, and description thereof will be omitted. explain.

  As shown in FIG. 9, in steps S150a and S200a, only energization to the blower 2 is interrupted (OFF), and energization to the Peltier element 30 is continuously executed. And after the electricity supply to the air blower 2 is interrupted (OFF), the flow path switching position of the flow path switching door 6 is switched. In steps S130 and S180, the energization polarity to the Peltier element 30 is reversed.

  In addition, you may perform "inversion of the electricity supply polarity to the Peltier device 30" performed in step S180 at the time of the "energization OFF to the air blower 2" in step S150a. Similarly, the “reversal of energization polarity to the Peltier element 30” executed in step S130 may be performed when “energization to the blower is OFF” in step S200a.

  According to such a configuration, during operation of the flow path switching door 6, the blower 2 is stopped (OFF), so that the humidified air is blown out from the humidified air outlet 8, that is, from the dehumidified air outlet 9. It will not be done. Thereby, since the water | moisture content capture | acquired by the adsorbent of the fin 33 is not thrown away wastefully, the humidification capability of the humidification air which blows off from the humidification air blower outlet 8 can be aimed at.

  In addition, immediately after the direction of the current flowing through the Peltier element 30 is reversed, the energization of the Peltier element 30 is continuously performed, so that the rising characteristics of the humidified air and the dehumidified air are improved.

(Third embodiment)
In the first and second embodiments described above, when the current flowing through the Peltier element 30 is reversed, the blower 2 is stopped (OFF) and the flow path switching door 6 is switched.

  FIG. 10 is a flowchart showing a control process of the control device in the present embodiment. In the flowchart of this embodiment, the same reference numerals are given to the same control processing configurations as those in the first and second embodiments described above, and description thereof will be omitted. The features will be described.

  As shown in FIG. 10, in steps S150b and S200b, energization to the blower 2 is continued, but the blower 2 is controlled to supply power that operates at a low rotation, and energization to the Peltier element 30 is continuously executed. Is done. And after electricity supply is controlled so that the rotation speed of the air blower 2 may become low rotation, the flow-path switching position of the flow-path switching door 6 is switched. In steps S130 and S180, the energization polarity to the Peltier element 30 is reversed. In steps S130 and S180, the blower 2 is energized at a normal rotational speed.

  In addition, you may perform "inversion of the electricity supply polarity to the Peltier device 30" performed in step S180, when the "blower is act | operated by low rotation" in step S150b. Similarly, the “reversal of the energization polarity to the Peltier element 30” executed in step S130 may be performed when “the blower is operated at a low speed” in step S200b.

  According to such a configuration, during the operation of the flow path switching door 6, the amount of air supplied to the first or second adsorption element 31 </ b> A, 31 </ b> B decreases, so that the humidified air is supplied to the humidified air outlet. A large amount is not blown out from the dehumidifying air outlet 9 except for 8. Thereby, since the water | moisture content capture | acquired by the adsorbent of the fin 33 is not thrown away wastefully, the humidification capability of the humidification air which blows off from the humidification air blower outlet 8 can be aimed at.
