BACKGROUND OF THE INVENTION
The present invention relates to a dehumidifying apparatus using an adsorbent mainly used for dehumidifying indoors and drying clothes in general households.
[0002]
[Prior art]
Conventionally, this type of dehumidifying apparatus is known from Japanese Unexamined Patent Publication No. 2000-126498.
[0003]
Hereinafter, the dehumidifier will be described with reference to FIG.
[0004]
As shown in the figure, the main body 101 of the dehumidifying device is provided with a drying air blow-out port 102 and a room air suction port 103. The main body 101 adsorbs moisture in the air at room temperature and adsorbs at a high temperature. The adsorbent 104, the heat exchanger 105, the heating means 106, the first blowing fan 107, the motor 108 for driving the first blowing fan, the second blowing fan 109, and the second blowing fan are dehumidified. A motor 110 for driving and a driving means 111 for rotating the adsorbent 104 are provided. Further, heat exchange is performed between the partition wall 112 that divides the adsorbent 104 into the adsorption side with the cooling fins of the heat exchanger 105 and the regeneration side with the heating means 106, the indoor air suction port 103, and the first blower fan 107. After connecting the cooling side of the vessel 105, the first wind tunnel 113 connected to the drying air blowing port 102 through the adsorption side of the divided adsorbent 104, the blowing port of the second blower fan 109 and the heating means 106, a second wind tunnel 115 having a drain hole 114 for connecting the regeneration side of the divided adsorbent 104, the circulation pipe side of the heat exchanger 105, and the suction port of the second blower fan 109. .
[0005]
The operation of the dehumidifier configured as described above will be described. Indoor air is sucked from the indoor air suction port 103 through the first wind tunnel 113 by the first blower fan 107, passes through the cooling side of the heat exchanger 105, The high-temperature and high-humidity circulating air that flows on the circulation pipe side of the heat exchanger 105 is cooled and heat-exchanged to become high temperature. Furthermore, it flows to the adsorption side of the adsorbent 104, and moisture is taken away, and at the same time, latent heat of vaporization is generated, which becomes dry high-temperature air and is discharged from the blowing air outlet 102 for drying air. On the other hand, the circulating air circulated by the second blower fan 109 flows from the outlet of the second blower fan 109 to the heating means 106, where it is heated to a high temperature and desorbs the moisture of the adsorbent 104 on the regeneration side of the adsorbent 104. The circulating air having a relatively high temperature and high humidity is guided into the circulation pipe of the heat exchanger 105, where it is cooled to the dew point temperature or less by the room air, and is again sucked into the suction port of the second blower fan 109 and circulated. The water recovered from the circulating air cooled below the dew point temperature is discharged to the outside from the drain hole 114.
[0006]
In addition, since the moisture adsorption amount of the adsorbent 104 is limited, the dehumidifying operation is performed by switching the adsorption side and the regeneration side of the adsorbent 104 continuously or intermittently by the driving unit 111.
[0007]
[Problems to be solved by the invention]

Moreover, since it is necessary to form an adsorbent, a heat exchanger, a heating means, a plurality of blower fans and a wind tunnel for connecting them in order in the main body, there is a problem that the main body is enlarged, There is a demand for downsizing the apparatus.
[0010]
In addition, when the heat exchanger is molded of resin, there is a problem that the dehumidification amount decreases due to the deterioration of the heat exchange capacity of the heat exchanger, and it is required to increase the heat exchange capacity of the heat exchanger. ing.
[0011]
In addition, there is a problem that the amount of dehumidification decreases because the heating means cannot efficiently regenerate the dehumidifying agent, and it is required to efficiently regenerate the dehumidifying agent and increase the dehumidifying efficiency.
[0012]
In addition, there is a problem that the pressure loss of the circulating air in the humidity transport region of the heating means increases and the dehumidification amount decreases due to the decrease of the circulating air flow rate. It is required to reduce the dehumidification amount by reducing the amount.
[0013]
Further, there is a problem that the adsorbent heating area of the heating means becomes too hot and is damaged, and it is required to protect the adsorbent heat heating area.

Embodiments of the present invention will be described below with reference to the drawings.
[0037]
【Example】
In the present embodiment, unless otherwise noted, the same parts as those described above are denoted by the same reference numerals, description thereof is omitted, and only different parts will be described.
[0038]
Example 1
FIG. 1 is a schematic view of the adsorbent 104 in the first embodiment of the present invention. The adsorbent 104 is a flat paper 1 made by mixing an adsorbent material such as silica gel, zeolite, lithium chloride or the like with inorganic fibers such as ceramic fibers or glass fibers, or a mixture of these inorganic fibers and pulp, and corrugated paper 2 with corrugated processing. Are stacked and rolled up to form a disk shape, and have a number of small through holes in the direction of the arrows in the figure, so that ventilation is possible. When the adsorbent 104 contains a relatively high amount of moisture, when relatively low humidity air, for example, heated air, passes the moisture into the passing air and the adsorbent is relatively dry It has the property of adsorbing moisture in the passing air when relatively humid air, for example, indoor air, passes through.
[0039]
FIG. 2 is a diagram illustrating the principle of the dehumidifying device according to the first embodiment of the present invention. The room air sucked into the main body 101 by the first blower fan 107 passes through the heat exchanger 105 while exchanging heat with the circulating air, and passes through the adsorption region 4 on the adsorption side of the adsorbent 104. At this time, the adsorbent 104 adsorbs moisture contained in the room air and simultaneously gives heat of adsorption to the room air. The room air is dehydrated and the temperature is raised, so that the relative humidity is low and the room air is blown into the room. On the other hand, the circulating air circulated by the second blower fan 109 is heated by the heating means 106 and becomes a high temperature and flows into the heat exchanger 105 through the regeneration region 3 on the regeneration side of the dehumidifying agent 104. At that time, since the adsorbent 104 releases the moisture adsorbed in the adsorption region 4 in the regeneration region 3, the circulating air becomes a high temperature and high humidity state. The circulating air is cooled to the dew point temperature or less by heat exchange with the room air in the heat exchanger 105, and the contained moisture is condensed. The condensed water is taken out as condensed water. The circulating air that has been cooled and condensed moisture passes through the heat recovery area 5 that is a part of the adsorption side of the adsorbent 104. At this time, the adsorbent 104 itself is heated while being heated in the regeneration area 3. In the heat recovery area 5, heat is supplied to the circulating air. The circulating air to which heat is applied is blown again to the heating means 106 by the second blower fan 109.
[0040]
With the above configuration, the circulating air after passing through the heat exchanger 105 takes away the heat stored in the adsorbent 104 when passing through the heat recovery area 5 of the adsorbent 104, and then the temperature rises. Since it passes, the energy input to the heating means 106 corresponding to the temperature rise, that is, the power consumption can be reduced.
[0041]
FIG. 3 is a schematic assembly view of the rotor set 6 for allowing the adsorbent 104 to be protected and rotated. The adsorbent 104 is accommodated in the cylindrical case 7, and the adsorbent 104 is prevented from dropping by a stopper 8 provided on one end surface of the case 7. A frame 9 is fitted along the outer periphery on the opposite end side of the case 7 and is fixed to the case 7 by screwing a plurality of locations. A boss receiving portion 10 is arranged at the center of the frame 9, and ribs 11 are radially bridged from the boss receiving portion 10, and the boss 12 that fits into the central shaft hole of the adsorbent 104 from the opposite side of the frame 9 is received by the boss receiving. By fixing the portion 10 by screwing, the relative positions of the case 7 and the boss 12 are defined, and the adsorbent 104 is protected and held. A gear 13 for enabling rotation of the rotor assembly 6 is easily formed on the outer periphery of the case 7 by integral molding with the case 7 and the stopper 8, and the frame 9 is free from rust and has a thin plate thickness. Since high strength is required, a stainless steel plate having a thickness of 0.4 to 1.0 mm, preferably 0.6 mm, is manufactured by pressing and bending.
[0042]
FIG. 4 is a schematic view of a partition plate 14 for storing and holding the rotor assembly 6 and for partitioning air that is sucked into the main body 101 and passes through the adsorption region 4 of the adsorbent 104 before and after the adsorbent 104. The partition plate 14 is a resin-molded product, and has a cylindrical ventilation opening 15 that allows ventilation to the adsorbent 104. The partition board 14 is positioned at the center of the ventilation opening 15, and is fitted into the boss 12 of the rotor assembly 6 so that the rotor assembly 6 rotates. And a rib 18a, 18b, 18c, 18d that bridges the rotating shaft 16 from the rotating shaft 16 to the outer ring 17 to prevent the partition plate 14 from warping. The rib 18a and the rib 18d are arranged in the vertical direction, the rib 18a is bridged toward the upper surface of the main body, and the rib 18d is bridged toward the lower surface of the main body. Further, the rib 18b is inclined at an angle A from the rib 18a, and the rib 18c is inclined at an angle B in the reverse rotation direction with respect to the rib 18b. The angle A is a numerical value that determines the ratio of the regeneration region 3 to the regeneration region 3 in the adsorbent 104, and is preferably 30 ° to 90 °, more preferably 45 ° to 60 °. The angle B is a numerical value that determines the ratio of the heat recovery region 5 in the adsorbent 104, and is preferably 10 ° to 60 °, more preferably 15 ° to 45 °. Further, the fan-shaped portion between the ribs 18a and 18b protrudes in the direction opposite to the insertion side of the rotor set 6 to form a first chamber 19 into which the circulating air that has passed through the regeneration side of the adsorbent 104 flows.

The second chamber 21 is provided with a cylindrical second connection pipe 22. Yes. The rotor assembly 6 is accommodated in the partition plate 14 having the above-described structure so that the frame 9 side faces the partition plate 14, and the gear 13 of the rotor assembly 6 is meshed with the gear 23 of the drive motor 111 as drive means attached to the partition plate 14. The rotary drive of the rotor set 6 is performed by operating the drive motor 111.
[0043]
FIG. 5 is a cross-sectional view schematically showing the mutual positional relationship when the rotor set 6 is housed in the partition plate 14. The outer ring 17 and the ribs 18a, 18b, 18c are positioned so as to maintain a slight gap C with the frame 9 of the rotor set 6 to compensate for the smooth rotational drive of the rotor set 6, and the outer ring 17, ribs 18a, 18b, 18c The structure has predetermined widths D and E in the direction facing the rotor set 6.
[0044]
With the above structure, even if a pressure difference is generated in the first chamber 19, the second chamber 21, and other ventilation openings 15, the mutual flow amount through the gap C can be suppressed to be extremely small. That is, a short circuit between the high-temperature and high-humidity circulating air that has passed through the regeneration side of the adsorbent 104 flowing into the first chamber and the low-temperature circulating air that has been cooled by the heat exchanger 105 that flows into the second chamber. Since the circuit is suppressed, the condensed water can be efficiently collected in the heat exchanger 105, and the dehumidification efficiency can be improved. The specific numerical value that exhibits the above effect is that the slight gap C between the outer ring 17 and the ribs 18b, 18c, 18d and the frame 9 is desirably 0.6 mm or less, more preferably 0.3 mm or less. The predetermined width D facing the rotor set 6 is 0.5 mm or more, more preferably 2.0 mm or more, and the predetermined width E facing the rotor set 6 of the ribs 14b, 14c, 14d is more preferably 5.0 mm or more. It is 10.0 mm or more. Even if the partition plate 14 is warped, the ribs 14a, 14b, 14c, and 14d do not come into contact with the adsorbent 104 directly against the frame 9, so that the adsorbent 104 is not scraped and powder does not come out. .
[0045]
FIG. 6 is a schematic view of a holding plate 24 that is attached to the opposite side of the partition plate 14 between the first chamber 19 and the second chamber 21 and holds the rotor set 6 and a return portion. The holding plate 24 has a fan shape that covers the projected area from the rib 18b to the rib 18c on the opposite surface, and the apex portion is screwed to the rotating shaft 16 and the outer peripheral portion is screwed to the partition plate 14. Is attached to the partition plate 14 to prevent and retain the rotor frame. The holding plate 24 corresponds to an area F of the first chamber 19 projected onto the rotor set 6, and includes a first opening 25 serving as an introduction section for introducing the circulating air that has passed through the heating means 106 into the adsorbent 104. Similarly, it corresponds to the projected area G of the second chamber 21 and is provided with a second opening 26 as a reflux part for refluxing the circulating air that has passed through a part of the adsorbent 104 on the adsorption side. The gaps between the first opening 25 and the second opening 26, the outsides of the first opening 25 and the outside of the second opening 26 are throttle parts 27a, 27b that are convex toward the rotor set 6. 27c is formed by drawing. The center lines of the throttle portions 27a, 27b, and 27c overlap the center lines of the ribs 18a, 18b, and 18c on the back side across the rotor assembly 6 when viewed from the direction of ventilation of the rotor assembly 6, and the center of the throttle assembly 27a. The angle A formed by the line and the center line of the throttle portion 27b is equal to the angle A formed by the rib 18a and the rib 18b, and the angle B formed by the throttle portion 27a and the throttle portion 27c is equal to the angle B formed by the rib 18a and the rib 18c. .
[0046]
FIG. 7 is a sectional view schematically showing the mutual positional relationship when the rotor set 6 is housed in the partition plate 14 and the holding plate 24 is attached. The holding plate 24 maintains a slight gap H between the stopper 8 and the boss 12 of the rotor set 6 and the throttle portions 27a, 27b, and 27c are positioned so as to maintain a slight gap I with the adsorbent 104. It encourages smooth rotation drive. The stopper 8 and the boss 12 have a predetermined width J and K in the direction facing the holding plate 24, respectively, and the predetermined width L is secured in the direction in which the throttle portions 27a, 27b, and 27c face the adsorbent 104. It has become.
[0047]
With the above structure, even if the air flowing through the first opening 25, the air flowing through the second opening 26, and the air flowing through the other opening of the adsorbent 104 have a pressure difference between them, the rotor assembly 6 and the sliding surface of the holding plate 24 are kept extremely small. That is, a short circuit between the circulating air that has passed through the heating means 106 that flows into the first opening 25 and the circulating air that has recirculated part of the adsorption side of the adsorbent 104 that flows into the second opening 26 is suppressed. Therefore, the energy input to the heating means 106 can be efficiently used for the regeneration of the adsorbent 104, and the dehumidification retail can be enhanced.
[0048]
In addition, since the first opening 25 as the introduction part and the second opening 26 as the reflux part are manufactured integrally, the gap between the introduction part and the adsorbent and the gap between the reflux part and the adsorbent are formed with high accuracy. In addition, the number of parts can be reduced and the cost can be reduced. Specific numerical values that exhibit the above effects are such that the slight gap H between the stopper 8 and the holding plate 24 and the slight gap I between the throttle portions 27a, 27b, 27c and the adsorbent 104 are 0.6 mm or less, more preferably 0.8. It is 3 mm or less, and the predetermined width J facing the holding plate 24 of the stopper 8 is 1.5 mm or more, more preferably 5.0 mm or more.

The facing predetermined width L is 5.0 mm or more, more preferably 10.0 mm or more. In addition, the holding plate 24 is required to have dimensional accuracy of the narrowed portions 27a, 27b, and 27c, and to be strong enough not to warp, and is also required to have rust prevention and heat resistance. It is desirable to produce by drilling and drawing, and the thickness is preferably 0.5 mm or more.

The regeneration chamber 29 has the heater 28 internally fixed, and a regeneration air outlet 31 is opened at a portion facing the first opening 25 of the holding plate 24. Further, a regeneration air suction port 32 is opened on the side surface on the throttle portion 27a side, and the blowout port 33 of the second blower fan is fitted into the regeneration air suction port 32. In addition, a reflection plate 37 is installed on the back surface of the heater 28 in the regeneration chamber 29 to reflect the radiant heat radiated from the heater 28 and direct it toward the rotor assembly 6 to effectively use the heat of the heater. . The reflection plate 37 is fixed or integrally formed with a heater frame 38 that fixes the heater 28 to the reproduction chamber 29. The reflecting plate 37 is made of a metal having a high surface reflectance, preferably an aluminum thin plate. In addition, the dividing plate 42 that divides the heating means 106 into the adsorbent heating region 39 and the moisture conveyance region 40 is formed using a heat-resistant member such as a sheet metal, a mica plate, a bakelite plate, and is fixed to the heater frame or integrally formed. Install. With the above configuration, most of the circulating air flowing from the regeneration air suction port 32 flows into the moisture transport region 40 and the passing air speed of the circulating air passing through the adsorbent 104 is increased. Even if the heater frame 38 has a function of dividing the heating means 106 into the adsorbent heating area 39 and the moisture transport area 40, there is no difference in effect. A punching member 41 as a rectifying grid is fixed to the heater frame 38, or is integrally formed, or is integrally formed with the holding plate 24 at a portion where the moisture conveyance region 40 of the regeneration air outlet 31 is projected. It is installed and rectifies the circulating air toward the regeneration area 3 of the adsorbent 104. The suction port 34 of the second blower fan opens in a direction facing the holding plate 24, and the connection duct 30 is interposed between the suction port 34 of the second blower fan and the holding plate 24. A third opening 35 corresponding to the suction port 34 of the second blower fan is opened on the surface of the connection duct 30 in contact with the second blower fan 109, and the second opening is formed in the direction facing the holding plate 24. Since the fourth opening 36 corresponding to 26 is opened, the air flowing out from the second opening 26 is smoothly guided to the suction port 34 of the second blower fan. In the actual assembly process, the second blower fan 109 and the connection duct 30 are fixed by screwing, and the suction port 34 of the second blower fan and the third opening 35 of the connection duct 30 are combined to be independent without a gap. After the air passage is formed, the blowout port 33 of the second blower fan is fitted into the regeneration air suction port 32 of the regeneration chamber 29 to form an independent air passage without a gap, and then the regeneration chamber 29 and the connection duct 30 are separated from the holding plate 24 or the partition. It is fixed to the plate 14 or both by screwing. At this time, the regeneration air outlet 31 and the first opening 25 of the holding plate 24 are combined to form an independent air path without a gap, and the fourth opening 36 of the connection duct 30 and the second opening of the holding plate 24 are provided. The independent air passage without gaps is combined to suck the air from the second opening 26 through the connection duct 30 with the second blower fan 109 and blow out into the regeneration chamber 29 to be discharged into the first chamber. An independent air passage through the opening 25 is completed. In addition, the 2nd ventilation fan 109 and the connection duct 30 are integrally molded, and it is good also as one component, and a difference does not arise in the effect. The rotor set 6 rotates in the direction of the arrow in FIG. 10, and after the adsorbent 104 adsorbs moisture in the room air in the adsorption region 4, the rotor set 6 rotates in the regeneration region 3. In the regeneration area 3, first, the adsorbent 104 is heated by the heat and radiant heat of the heater 28 at a position facing the adsorbent heating area 39 of the heating means 106. At this time, moisture adsorbed on the adsorbent 104 is detached from the surface of the adsorbent 104. Next, in the moisture transport area 40, the circulating air rectified by the punching member 41 passes through the adsorbent 104 rotated from the adsorbent heating area 39, so that the moisture separated from the adsorbent 104 in the adsorbent heating area 39.

[0050]
As described above, the heating means 106 is divided into the adsorbent heating area 39 and the moisture transport area 40, and the adsorbent is heated by suppressing the circulating air flowing in the adsorbent heating area 39 and increasing the temperature and radiant heat of the heater 28. The moisture removal from the adsorbent 104 is promoted, and the moisture transport area 40 increases the passing air velocity of the circulating air passing through the adsorbent 104, thereby transporting the moisture separated from the adsorbent 104 at a stretch. Can be improved.

[0055]
Further, as shown in FIG. 10, the adsorbent 104 from which moisture has been desorbed in the moisture transport region 40 is in a state where a part of heat given by the heating means 106 is stored, and in this state, moisture cannot be adsorbed. . The adsorbent 104 in the above state rotates to the heat recovery area 5. In the heat recovery area 5, the circulating air that has been subjected to heat exchange with room air in the heat exchanger 105 and has become low temperature passes through the adsorbent 104. At this time, the circulating air is heated by the heat stored in the adsorbent 104. On the other hand, the moisture in the circulating air passes as it is because the adsorbent 104 cannot absorb moisture. The circulating air that has passed through the heat recovery area 5 is blown to the heating means 106 by the second blower fan 109. Therefore, since the temperature of the circulating air flowing into the heating means 106 can be raised, the input energy to the heating means 106 corresponding to the temperature rise, that is, the power consumption can be reduced. In the dehumidifying device of this configuration, a dehumidifying amount equivalent to that of the conventional dehumidifying device can be obtained with an input heat amount of 75 to 80%.

If a heater using radiation, such as a halogen heater, is used as the heater 28, the adsorbent can be efficiently regenerated by using radiation heat more effectively, and the dehumidification efficiency can be further increased.

FIG. 11 is a schematic configuration diagram of the heat exchanger 105 that exchanges heat between the circulating air that has become hot and humid in the regeneration region 3 of the adsorbent 104 and the room air. The first, second, and third heat exchangers 44, 45, and 46 are made by blow molding (or twin sheet vacuum molding) of a resin material (preferably polypropylene), and circulating air flows in a substantially vertical direction. A circulating air passage air passage 47 is formed, and an indoor air passage air passage 48 through which room air flows in a substantially horizontal direction is formed. One end face of the first heat exchanger 44 is provided with a heat exchanger inlet duct 49 leading to the circulating air passage air passage 47, and the first heat exchange connection duct 50a is provided on the other end face with the heat exchanger inlet duct. 49, the second heat exchange connection duct 50b is arranged vertically downward as much as possible. In addition, a third heat exchange connection duct 50c is arranged at a position facing the first heat exchange connection duct 50a on the end face of the second heat exchanger 45 facing the first heat exchanger, The heat exchange connection duct 50d is arranged at a position facing the second heat exchange connection duct, and the fifth heat exchange connection duct 50e is opposed to the fourth heat exchange connection duct 50d on the other end face. It is arranged. Further, the end face of the third heat exchanger 46 facing the second heat exchanger 45 is arranged with a heat exchanger outlet duct 51 at a height close to the heat exchanger inlet duct 49 in the vertical vertical direction, The sixth heat exchange connection duct 50f is arranged at a position facing the fifth heat exchange connection duct 50e. Further, all the heat exchangers are provided with a condensed water outlet 52 at the bottom in the vertical direction. The first heat exchange connection duct 50a and the third heat exchange connection duct 50c are connected, and the second heat exchange connection duct 50b is connected to the fourth heat exchange connection duct 50d, whereby the first heat exchange is performed. The first heat exchanger 45 and the second heat exchanger 45 are coupled, and the fifth heat exchange connection duct 50e is connected to the sixth heat exchange connection duct 50f. The exchangers 44, 45, 46 are combined. Further, the first, second, and third heat exchangers 44, 45, and 46 are fixed more securely by screwing four corners or diagonally two corners. The circulating air flows into the first heat exchanger 44 from the heat exchanger inlet duct 49, and a part of the circulating air passes through the circulating air passage air passage 47 of the first heat exchanger 44 through the indoor air passage air passage 48. It flows downward while exchanging heat with and flows into the second heat exchanger 45 from the second connection duct 50b. Other circulating air passes through the first connection duct 50a and the third connection duct 50c and flows into the second heat exchanger 45, and passes through the circulating air passage air passage 47 of the second heat exchanger 45 through the room air. It flows downward while exchanging heat with indoor air flowing through the air passage 48. The circulating air that has flowed through the first heat exchanger 44 and the second heat exchanger 45 in the fifth connection duct 50e merges and flows into the third heat exchanger 46. Further, the circulating air flows upward through the circulating air passage air passage 47 of the third heat exchanger while exchanging heat with the indoor air flowing through the indoor air passage air passage 48, and flows out from the heat exchanger outlet duct 51. Under the assumption of this heat exchange, the circulating air is cooled by room air, moisture in the circulating air is condensed, and water droplets adhere to the circulating air passage air passage 47. The adhering water droplets flow down through the circulating air passage air passage 47 and are taken out from the condensed water outlet 41. In order to prevent the second connection pipe 22 extending from the partition plate 14 to the heat exchanger outlet duct 51 from interfering with the first heat exchanger 44 and the second heat exchanger 45, the first heat exchange is performed. A cutout 53 is provided in the heat exchanger 44 and the second heat exchanger 45.
[0058]
  By adopting the above configuration, it is possible to configure an air passage in which the positions of the heat exchanger inlet duct 49 and the heat exchanger outlet duct 51 are close to each other in the vertical direction, and the heat transfer area of the heat exchanger 105 is small. The heat exchanger 105 with good heat exchange efficiency can be obtained without loss. Further, since the circulating air flows downward in the circulating air passage air passage 47 of the first heat exchanger 44 and the second heat exchanger 45, the passing air speed of the circulating air is increased and the fall of water droplets adhering to the inside is promoted. Thus, the heat exchange performance can be improved, and the circulating air flows in the upward direction in the circulating air passage air passage 47 of the third heat exchanger 46. Therefore, it is preferable to slow the passing air speed. In this embodiment, the above-described control of the passing wind speed is realized by changing the widths N, O, and P of the first, second, and third heat exchangers. That is, the widths N and O of the first and second heat exchangers in which the circulating air flows downward are 15 mm, and the width P of the third heat exchanger in which the circulating air flows upwards are N and O The first and second heat exchangers 44 and 45 increase the passing air speed of the circulating air, and the third heat exchanger 46 relatively decreases the passing air speed. In addition, the heat exchanger 105 may be molded using a material having good heat conduction characteristics and corrosion resistance other than the resin material, and there is no significant difference in its effect and action.Further, in the heat exchanger, the traveling direction of the circulating air is reversed during the heat exchange with the room air, and the inlet of the circulating air to the heat exchanger and the outlet of the heat exchanger are brought close to each other in a substantially vertical direction. The circulation path is arranged in this way, and the heat exchanger introduction path and the discharge path of the circulation air are approached by reversing the traveling direction of the circulation air in the course of heat exchange. The wind tunnel connecting the two can be configured in a short distance and in a straight line, and the length of the circulating air in the heat exchanger can be increased to increase the heat exchange efficiency and reduce the size of the heat exchanger. The direction of the circulating air is reversed in the course of heat exchange with the room air, and the inlet of the circulating air to the heat exchanger and the outlet from the heat exchanger are provided. Approximately vertical direction Since the circulation path is arranged so as to be close to each other, the air tunnel connecting the heat exchanger and the adsorbent can be arranged in a short distance and in a straight line so that the passage distance of the circulating air can be secured. In addition, it is possible to provide a dehumidifying device that has the effect of improving the heat exchange efficiency and reducing the size of the heat exchanger to a compact body size.
[0059]
Further, the heat exchange efficiency of the heat exchanger 105 can be further improved by incorporating a heat transfer promoting substance such as an aluminum pigment or barley stone into the resin material.
[0060]
Fig. 12 shows the heat exchange when using a heat exchanger molded with polypropylene as a general resin material, a heat exchanger molded with polypropylene containing an aluminum pigment, and a heat exchanger molded with polypropylene and barley stone. Experimental data on efficiency is shown. Dehumidifying performance is improved when aluminum pigment and barley stone are included, compared to a single polypropylene material, especially when barley stone is included. As a result, the size can be further reduced. FIG. 13 shows experimental data on the heat exchange efficiency of the heat exchanger when the content of barleystone contained in polypropylene is changed. From the experimental results, the content of barleystone was about 1.2%, which was a good value.
