Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a drier that dehumidifies air to dry clothes, or dries a bathroom, indentation, or room.
[0002]
[Prior art]
  A conventionally used clothes dryer has a structure as shown in FIG. That is, for example, the air blowing means 5 circulates air through the adsorbent 2 and circulates air in the drying chamber 1 containing clothes that can be assembled with vinyl or the like. As the air blowing means 5, for example, a sirocco fan is used. As the adsorbent 2, silica gel or zeolite is used. Reference numeral 4 denotes a regeneration air passage that guides the air outside the drying chamber 1 to the adsorbent 2 and guides the air outside the drying chamber 1 again. Further, air path switching means 7 and 8 constituted by a damper or the like are for switching between the circulation air path 3 and the regeneration air path 4. The heating means 6 is arranged on the windward side of the adsorbent 2 and is energized by an instruction from the control means 9 to supply hot air to the adsorbent 2. By supplying this high-temperature air, the adsorbent 2 is regenerated by releasing the adsorbed moisture. That is, when the control means 9 recognizes that the total adsorption time of the adsorbent 2 has reached a predetermined time, the heating means 6 is energized to regenerate the adsorbent 2. In this regeneration process, the control means 9 operates the air path switching means 7 and 8 so that the regeneration air path 4 side is opened and the circulation air path 3 side is closed, and the adsorbent 2 contains moisture adsorbed. Instead of circulating the air inside the drying chamber 1, the air passes through the regeneration air passage 4 and is discharged out of the drying chamber 1.
[0003]
  With the above configuration, when the user operates an operation unit (not shown) and starts operation, the control unit 9 switches the air path switching unit 7 and the air path switching unit 8 so that the circulation air path 3 is opened. The blowing means 5 is operated in the operated state. By the operation of the blowing means 5, the air in the drying chamber 1 is repeatedly circulated through the adsorbent 2 and sent to the drying chamber 1 again. At this time, the air that has passed through the adsorbent 2 is dehumidified by adsorbing moisture by the adsorbent 2, and at the same time becomes high temperature and low humidity by the heat of adsorption generated by the adsorbent 2. This high-temperature, low-humidity dry air circulates in the drying chamber 1 containing clothes such as laundry, so that it is replaced with air that has become humid due to moisture from the clothes, and the high-temperature, low-humidity air and the clothes are in contact with each other. As a result, the clothes such as the laundry are dried. Further, when a predetermined time has elapsed since the start of drying, the control means 9 operates the air path switching means 7 and the air path switching means 8 to open the regenerating air path 4. At the same time, the heating means 6 is energized to heat the air outside the drying chamber 1 blown by the blowing means 5. This heated air is in contact with the adsorbent 2 to heat the adsorbent 2 and release the moisture adsorbed by the adsorbent 2. Since the regeneration air passage 4 is open, the released moisture is discharged from the regeneration air passage 4 to the outside of the drying chamber 1 by the air blowing by the air blowing means 5. Thus, the adsorbent 2 is regenerated and the moisture adsorption capacity is restored. The adsorption and regeneration as described above are repeatedly performed by the control means 9, and the drying of the clothes such as the laundry accommodated in the drying chamber 1 proceeds.
[0004]
  In the above description, the drying chamber 1 has been described as containing clothes that can be assembled freely with vinyl or the like. However, if the drying chamber 1 is treated as a room in a house such as a bathroom or a closet, for example, the same configuration is used. It will be a bathroom dryer and an intrusion dryer.
[0005]
[Problems to be solved by the invention]
  The conventional clothes dryer, bathroom dryer, or intrusion dryer has a problem of low energy efficiency. That is, the air after regenerating the adsorbent by the heating means has a high temperature even after the regeneration, and this energy is exhausted from the regeneration air passage to the outside of the drying chamber. In addition, the regeneration air released to the outside of the drying chamber is humid and has a problem of increasing the humidity outside the drying chamber.
[0006]
[Means for Solving the Problems]
  The present inventionThe heat exchanger is provided with second blowing means for blowing air outside the drying chamber, and the air outside the drying chamber blown by the second blower is branched before the heat exchanger, and the regenerated air flowing through the heat exchanger On the upstream side, the regeneration air that has passed through the heating means and the adsorbent is cooled by new regeneration air sucked from outside the drying chamber, and on the downstream side of the regeneration air flowing through the heat exchanger, cooling air sucked from outside the drying chamber Was further cooled byIs.

【Example】
  (Example 1)
  A first embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a cross-sectional view showing the configuration of this embodiment. Reference numeral 10 denotes, for example, a drying room that can be assembled freely with vinyl or the like that houses clothes such as laundry, or a room in a house such as a bathroom or a closet. (In the following description, it is assumed that the drying chamber 10 houses clothes such as laundry.) A circulation air passage 12 constituted by a duct or the like is connected to the upper and lower portions of the drying chamber 10. In the circulation air passage 12, a first air blowing means 14, an adsorbent 11, and a heating means 15 are provided. In the present embodiment, the first blower unit 14 uses a centrifugal blower, and circulates the air sucked from the drying chamber 10 into the drying chamber 10 again through the adsorbent 11. is there. A heating means 15 is arranged on the wind of the adsorbent 11.
[0010]
  Further, a regenerative air passage 13 constituted by a duct or the like is provided in the middle of the circulation air passage 12. The regeneration air passage 13 is connected to the circulation air passage 12 via air passage switching means 17 and 18 constituted by a damper or the like. The air path switching means 17 and 18 operate in accordance with instructions from the control means 21, and the state shown by the solid line in FIG. 1 indicates the state where the circulation air path 12 is blocked and the regenerative air path 13 is used. ing. On the contrary, the state indicated by the dotted line indicates a state in which the regeneration air passage 13 is blocked and the circulation air passage 12 is used. A plurality of heat exchangers 19 a and 19 b are disposed in the regeneration air passage 13. That is, the air outside the drying chamber 10 sucked by the second air blowing means 18a from the air inlet 13a is heated by the heating means 15, flows through the regeneration air passage 13, and heats the adsorbent 11, and then heats the heat exchanger 19a. After passing through the exchanger 19b, the air is exhausted from the exhaust port 13b. At the same time, a cooling air passage 42 is connected to a part of the regeneration air passage 13. The cooling air passage 41 is provided with the heat exchanger 19b and the second air blowing means 18b. That is, the air outside the drying chamber 10 taken in by the second air blowing means 18b from the air inlet 42a is exhausted from the air outlet 42b through the heat exchanger 19b. As a result, the air flowing from the heat exchanger 19b to the exhaust port 13b is further cooled to become low humidity.
[0011]
  Further, the regeneration air passage 13 is provided with drain holes 22a and 22b for discharging condensed water generated in the heat exchangers 19a and 19b to the outside of the system.
[0012]
  In this embodiment, a centrifugal sirocco fan is used as the first blower means 14 and the second blower means 18a, 18b. However, it is not necessary to be limited to the centrifugal sirocco fan. In this embodiment, the adsorbent 11 is a silica gel or zeolite molded product. The heating means 15 is constituted by a nichrome heater, a ceramic heater having a positive resistance temperature coefficient, or the like.
[0013]
  The operation of this embodiment will be described below. When the user operates an operation section (not shown) and starts operation, the control means 21 operates the air path switching means 16 and the air path switching means 17 to open the circulation air path 12 and at the same time the first The air blowing means 14 is operated. By the operation of the first air blowing means 14, the air in the drying chamber 10 circulates using the circulation air passage 12 provided in the upper portion of the drying chamber 10 and the lower portion of the drying chamber 10. An adsorbent 11 is disposed in the circulation air passage 12. Therefore, the circulating air blown by the first air blowing means 14 always comes into contact with the adsorbent 11. By this contact, the air that has passed through the adsorbent 11 is dehumidified by the moisture contained in the air being adsorbed by the adsorbent 11, and at the same time, the heat of adsorption generated by the adsorbent 10 is obtained to obtain high-temperature and low-humidity dry air. It will be. Thus, the high-temperature and low-humidity dry air supplied from the lower part of the drying chamber 10 functions to dry clothes such as laundry accommodated in the drying chamber. The air that has become low-temperature and high-humidity containing moisture evaporated from the clothes due to the contact with the clothes such as the laundry is sucked in from the upper part of the drying chamber 10 by the first air blowing means 14 and again through the adsorbent 11. In the lower part of the drying chamber 10, high-temperature and low-humidity dry air is supplied. Thus, by the circulation of the dry air using the circulation air passage 12, the humid air in the drying chamber 10 is replaced with the dry air, and the drying of clothes such as the laundry in the drying chamber 10 proceeds. Moreover, when the drying room 10 is a room of a house such as a bathroom or a close-in, for example, the drying of the bathroom or close-in proceeds.
[0014]
  In this embodiment, the control means 21 operates the air path switching means 16 and the air path switching means 17 to close the circulation air path 12 and open the regenerative air path 13 after a predetermined time has elapsed since the start of drying. Instruct to open. That is, when the adsorbent 11 adsorbs a large amount of moisture and the adsorption capacity is reduced, the regeneration process is executed. In this regeneration process, the adsorbent 11 is regenerated by heating the adsorbent 11 by the heating means 15 and releasing a large amount of water adsorbed by the adsorbent 11 from the adsorbent 11. In this regeneration process, the control means 11 gives an instruction to energize the heating means 15 simultaneously with the operation of the air path switching means 16 and the air path switching means 17. Accordingly, the regenerated air sucked from the air inlet 13a provided outside the drying chamber 10 by the second air blowing means 18a passes through the heat exchanger 19a and is then heated by the heating means 15 to become a high temperature and contact the adsorbent 11. To do. The temperature of the adsorbent 11 rises due to the contact with the high-temperature air, and the moisture absorbed by the adsorbent 11 during the circulation is released from the adsorbent 11. The regenerated air containing the released water and becoming humid is exhausted from the exhaust port 13b to the outside of the drying chamber 10 through the regenerative air passage 13, the heat exchanger 19a and the heat exchanger 19b.
[0015]
  At this time, as described above in the present embodiment, the regeneration air passage 13 is provided with two heat exchangers 19a and 19b. The heat exchanger 19a acts to preheat the air outside the drying chamber 10 sucked from the air inlet 13a. That is, most of the heat energy used for the air heated to high temperature by energization of the heating means 15 is used by heating the adsorbent 11, but when the heat reaches the heat exchanger 19a, it still has considerable heat. It has energy. Therefore, in this embodiment, the heat energy is exchanged with the air outside the drying chamber 10 sucked from the intake port 13a using the heat exchanger 19a. As a result, the air outside the drying chamber 10 sucked from the air inlet 13a is heated, and therefore the energization amount of the heating means 15 can be reduced..
[0016]
  In the present embodiment, the dried air that has passed through the heat exchanger 19a and discharged condensed water generated in the heat exchanger 19a out of the system through the drain holes 22a is further heated as described above. The condensed water generated by passing through the exchanger 19b is discharged out of the system through the drain hole 22b, and then exhausted out of the drying chamber 10 through the exhaust port 13b. At this time, the heat exchanger 19b exchanges heat between the cooling air outside the drying chamber 10 sucked by the second air blowing means 18b from the air inlet 42a and the air passing through the heat exchanger 19a. By the heat exchange using this cooling air passage 42, the air that has passed through the heat exchanger 19b is further reduced in humidity. Further, the condensed water generated by heat exchange is discharged out of the system through the drain hole 22b. Note that the cooling air sucked from the air inlet 42a by the second air blowing means 18b is heated and slightly raised in temperature, and is exhausted outside the drying chamber 10 from the air outlet 42b.
[0017]
  That is, according to the present embodiment, heat is exchanged between the regenerated air before heating and the regenerated air whose temperature is high and humid due to residual heat after regeneration, and the heat exchanger 19a. On the other hand, the air outside the drying chamber 10 sucked in by the second air blowing means 18b is sent to the heat exchanger 19b through the cooling air passage 42, and in the heat exchanger 19b, heat is exchanged with the regenerated air after passing through the heat exchanger 19a. Thus, the regeneration air is further cooled.
[0018]
  As described above, according to this embodiment, the humid and relatively high-temperature regeneration air after passing through the adsorbent 11 is passed through the adsorbent 11 and the heating means 15 using the heat exchanger 19a. By exchanging heat with the air outside the drying chamber 10 at a relatively low temperature, the heat energy of the regenerated air can be recovered including sensible heat and latent heat.
[0019]
  As a result, the temperature of the air blown to the heating means 15 becomes higher than the temperature of the air outside the drying chamber 10, so that the power consumed by the heating means 15 for raising the regeneration air to a predetermined temperature is reduced. It can be done. That is, a dryer with high energy efficiency can be realized.
[0020]
  Further, in the present embodiment, the heat exchanger 19b is used to exchange heat with the air that has passed through the heat exchanger 19a, so that the humidity of the air that has passed through the heat exchanger 19a is further reduced. It is what. For this reason, it is set as the dryer which can prevent the increase in the humidity outside the drying chamber 10.
[0021]
  In this embodiment, two heat exchangers 19a and 19b are used, but there is no problem even if two or more heat exchangers are used, and the number of heat exchangers used is particularly limited. It is not limited to two.
[0022]
  Further, in this embodiment, the second air blowing means is composed of two units 18a and 18b. However, the same effect can be obtained even if there are two or more units. Moreover, although the motor and the sirocco fan are used as the 1st ventilation means 14 and the 2nd ventilation means 18a, 18b, a present Example limits the structure of the 1st ventilation means 14 and the 2nd ventilation means 18a, 18b. is not. Moreover, although the motor is used for each of the 1st ventilation means 14 and the 2nd ventilation means 18a and 18b, it is set as the structure which rotates 2 units | sets or 3 units | sets, sharing one motor. Is also possible. In addition, as for the installation positions of the first blowing means 14 and the second blowing means 18a and 18b, as long as the air in the drying chamber 10 or the air outside the drying chamber 10 can be blown in a predetermined direction in each air passage. There is no particular limitation.
[0023]
  (Example 2)
  Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a cross-sectional view showing the configuration of this embodiment. Portions common to the first embodiment are denoted by the same reference numerals and description thereof is omitted. In the present embodiment, one heat exchanger 20 is disposed in the regeneration air passage 13. Further, in this embodiment, the second air blowing means 43 is provided as one unit, and the regeneration air passage and the cooling air passage described in Embodiment 1 are partitioned inside. That is, the air sucked from the outside of the drying chamber 10 by the second blowing means 43 passes through the heat exchanger 20, one is blown to the heating means 15 as regeneration air, and the other is the exhaust air as cooling air. The air is exhausted from the drying chamber 10 through 42b or 42c. This cooling air further cools the regenerated air by the heat exchanger 20. Reference numeral 21 denotes control means for controlling each part. Reference numeral 23 denotes a drain hole provided in the regeneration air passage 13 for discharging condensed water generated in the heat exchanger 20.
[0024]
  In this embodiment, a centrifugal sirocco fan is used as the second air blowing means 43, but it is not necessary to be limited to a centrifugal sirocco fan.
[0025]
  The operation of this embodiment will be described below. When the user operates an operation section (not shown) and starts operation, the control means 21 operates the air path switching means 16 and the air path switching means 17 to open the circulation air path 12 and at the same time the first The air blowing means 14 is operated. By the operation of the first air blowing means 14, the air in the drying chamber 10 circulates using the circulation air passage 12 provided in the upper portion of the drying chamber 10 and the lower portion of the drying chamber 10. By this circulation, high-temperature dry air dried by the adsorbent 11 is supplied into the drying chamber 10, and drying of clothes such as laundry in the drying chamber 10 proceeds.
[0026]
  When a predetermined time has elapsed since the start of drying, the control means 21 operates the air path switching means 16 and the air path switching means 17 to instruct to open the regeneration air path 13. At the same time, the second air blowing means 43 is operated, and at the same time, an instruction to energize the heating means 15 is given to execute the regeneration process of the adsorbent 11 described in the first embodiment. The regenerative air blown by the second blower means 43 passes through the heat exchanger 20 and is heated by the heating means 15 so as to reach a high temperature and contact the adsorbent 11. The temperature of the adsorbent 11 rises due to the contact with the high-temperature air, and the moisture absorbed by the adsorbent 11 during circulation is released from the adsorbent 11. Thus, the adsorbent 11 is regenerated. The regenerated air that has become humid with the released moisture passes through the regenerative air passage 13, passes through the heat exchanger 20, and is exhausted outside the drying chamber 10. At this time, the heat exchanger 20 exchanges heat between the high-temperature regenerated air that has passed through the regenerative air passage 13 and the air that the second air blowing unit has taken in from outside the drying chamber 10. Accordingly, the air sucked from outside the drying chamber 10 is heated and sent to the heating means 15. Therefore, as described in the first embodiment, the heating amount in the heating means 15 can be reduced, and highly efficient drying can be executed.
[0027]
  Further, as described in the first embodiment, the high-temperature and high-humidity regenerated air containing moisture separated from the adsorbent 11 is cooled by the second air blowing unit 43 from the outside of the drying chamber 10 by the heat exchanger 20. The heat is exchanged to become low-temperature and low-humidity and exhausted from the exhaust port 42b and the exhaust port 42c. At this time, since a large amount of cooling air is sucked from the air inlet 42a, a small amount of regenerated air that passes through the heat exchanger 20 is efficiently heat-exchanged and cooled. That is, the cooling air exhausted from the exhaust port 42b and the exhaust port 42c has very low humidity and does not humidify the outside air.
[0028]
  As described above, according to the present embodiment, the humid and relatively high-temperature regeneration air after passing through the adsorbent 11 is passed through the adsorbent 11 and the heating means 15 using the heat exchanger 20. By exchanging heat with the air outside the drying chamber 10 at a relatively low temperature, the heat energy of the regeneration air can be efficiently recovered. As a result, the regeneration air supplied to the heating means 15 is higher than the temperature of the outside air, so that the amount of heating in the heating means 15 can be reduced and a highly efficient dryer can be realized. Furthermore, since the regeneration air is condensed using the heat exchanger 20, the amount of moisture released to the outside of the drying chamber 10 can be reduced, and the outside air is not humidified.
[0029]
  Further, in this embodiment, since one heat exchanger 20 is used and the regeneration air passage and the cooling air passage are separated from each other, one heat exchanger and two heat exchangers are used. The same effect can be obtained. That is, the number of parts can be reduced by reducing the number of heat exchangers to one.
[0030]
  Further, in this embodiment, the second air blowing means 43 is used as one unit, and the air path that matches the required air volume is divided and used between the regeneration air and the cooling air. An effect equivalent to that using the air blowing means can be obtained, and the number of parts can be reduced.
[0031]
  In this embodiment, a motor is used for each of the first air blowing means 14 and the second air blowing means 43. However, it is also possible to use a structure in which one motor is shared and two fans are rotated. Is possible. Further, the installation positions of the first blower means 14 and the second blower means 43 are also particularly limited as long as the air inside the drying chamber 10 or the air outside the drying chamber 10 can be blown in a predetermined direction in each air passage. Not what you want.
[0032]
  (Example 3)
  Next, a third embodiment of the present invention will be described. FIG. 3 is a cross-sectional view showing the configuration of this embodiment. The circulation air passage 25 is constituted by a duct or the like, is connected to the upper and lower portions of the drying chamber 10, and includes a first air blowing means 27. An adsorbent 24 adsorbs moisture from the air in the drying chamber 10. The air sucked from the upper part of the drying chamber 10 through the circulation air passage 25 by the first blowing means 27 is dehumidified by the adsorbent 24 and is blown and circulated to the lower part of the drying chamber 10. A regenerative air passage 26 is provided so as to be in contact with or integrated with the circulation air passage 25, and heat exchangers 30a, 30b, a heating means 29, and the adsorbent 24 are arranged therein. 28a and 28b are a plurality of second air blowing means. The air sucked by the second air blower 28a from the air intake port 28c that opens to the outside of the drying chamber 10 passes through the regenerative air passage 26 from the heat exchanger 30a as regenerated air, and then the heating means 29, the adsorbent 24, and the heat exchange. The air is exhausted from an exhaust port 30c that is open to the outside air through the heat exchanger 30a and the heat exchanger 30b. On the other hand, the air outside the drying chamber 10 sucked in by the second air blowing means 28 b is blown from the cooling air passage 44 to the heat exchanger 30 b as cooling air and is discharged outside the drying chamber 10. The cooling air is heat-exchanged with the regenerated air that has passed through the heat exchanger 30a in the heat exchanger 30b to cool the regenerated air.
[0033]
  Reference numeral 32 denotes control means for controlling each means. 33a and 33b are drain holes provided in the regenerative air passage 26 for discharging condensed water generated in the heat exchangers 30a and 30b.
[0034]
  Further, the adsorbent 24 used in this embodiment has a configuration as shown in FIG. FIG. 4 is a perspective view showing the configuration of the adsorbent 24. The adsorbent 24 has a structure in which silica gel or zeolite is molded into a cylindrical shape, and has a honeycomb structure in which a large number of through holes are opened so that air flows in the axial direction as illustrated. Further, the adsorbent 24 is configured to always rotate by the rotating means 35. The rotating means 35 is constituted by a rotor motor 36 and a belt 37. That is, the adsorbent 24 is rotated as a whole when the rotation of the rotor motor 36 is transmitted by the belt 37. A partition plate 38 and a partition plate 39 are provided on the surface of the adsorbent 24, and the adsorbent 24 is partitioned into an adsorption zone 40 and a regeneration zone 41. A circulation air passage 25 is connected to the adsorption zone 40, and the air from the drying chamber 10 blown by the first blowing means 27 is dehumidified and returned to the drying chamber 10 again. A regeneration air passage 26 is connected to the regeneration zone 41, and after the air outside the drying chamber 10 has passed through the heating means 29, the air is sent to the regeneration zone 41, and after passing through the adsorbent 24, the heat exchanger 30a. , 30b is exhausted from the exhaust port 30c.
[0035]
  As described above, the adsorbent 24 of the present embodiment is rotated by the rotating means 35 and rotates and moves alternately between the adsorption zone 40 and the regeneration zone 41. That is, the adsorbent 24 dehumidifies the air in the adsorption zone 40 by rotating, then is heated and regenerated in the regeneration zone 41, moves again to the adsorption zone 40, repeats adsorption and regeneration, and passes continuously. It dehumidifies the circulating air.
[0036]
  The operation of this embodiment will be described below. When the user operates an operation unit (not shown) to start operation, the control unit 32 activates the first blowing unit 27, the second blowing unit 28a and 28b, the heating unit 29, and the rotor motor 36. The air in the drying chamber 10 circulates through the circulation air passage 25 and the adsorbent 24 by the first air blowing means 27. The air that has passed through the adsorbent 24 is dehumidified by adsorbing moisture to the adsorbent 24 to obtain heat of adsorption to become high-temperature and low-humidity dry air. Drying proceeds in the drying chamber 10 by the circulation of the dry air. That is, when the drying chamber 10 is used as a clothes dryer, the drying of the housed clothes proceeds, and when the drying chamber 10 is used as a bathroom, the drying of the bathroom proceeds. In the case of indentation, indentation drying proceeds. At the same time, the air sucked from the air inlet 28c opened to the outside of the drying chamber 10 by the second air blowing means 28a passes through the heat exchanger 30a and is sent to the heating means 29. The air heated to a high temperature by energization of the heating means 29 passes through the regeneration zone 41 of the adsorbent 24 and releases the moisture absorbed by the adsorbent 24. Therefore, the adsorbent 20 is regenerated by rotating through the regeneration zone 41 and adsorbs moisture again in the adsorption zone 40. Further, the regenerated air containing moisture generated by this regeneration and having become highly humid passes through the regeneration air passage 26 by the second air blowing means 28a, and is exhausted from the exhaust port 30c through the heat exchangers 30a and 30b. Is done. While passing through the heat exchanger 30a, the second air blowing means 28a heats the air taken in from the air inlet 28c that is open to the outside air. That is, as described in the first embodiment, the heat energy of the regeneration air is supplied to the new regeneration air sucked from the intake port 28c by heat exchange. Therefore, also in the present embodiment, the humid and relatively high-temperature regeneration air after passing through the regeneration zone 41 of the adsorbent 24 passes through the adsorbent 24 and the heating means 29 using the heat exchanger 30a. The heat energy of the regeneration air can be recovered by exchanging heat with the air outside the previous relatively low temperature drying chamber 10. Moreover, in the heat exchanger 30b, since a small amount of regenerated air after passing through the heat exchanger 30a is cooled by a large amount of cooling air outside the drying chamber 10, the regenerated air is cooled to become low humidity. . The condensed water generated at this time is drained out of the system through drain holes 33a, 33b provided in the regeneration air passage 26.
[0037]
  According to this embodiment, the adsorbent 24 is rotated by the rotating means 35 so that the adsorption zone 40 and the regeneration zone 41 are alternately passed, so that the adsorption and regeneration steps can be executed simultaneously. Thus, it is possible to realize a dryer that can continuously perform adsorption dehumidification and has a high dehumidifying capacity. In this embodiment, the rotor motor 36 and the belt 37 are used as the rotating means 35. However, the central axis of the adsorbent 24 is directly rotated by the motor.MakeThe rotation method of the adsorbent 24 is not particularly limited.
[0038]
  Further, in this embodiment, as shown in FIG. 4, the regeneration air passes through the adsorbent 24 after passing through the heating means 29. However, the configuration shown in FIG. Is possible. That is, it is also conceivable that the air once having passed through the adsorbent 24 is heated by the heating means 29 and the air that has been heated is passed through the adsorbent 24 again. That is, the present embodiment does not particularly limit the flow of the regeneration air that passes through the adsorbent 24.
[0039]
  In this embodiment, a motor and a sirocco fan are used as the first blower means 27 and the second blower means 28a, 28b, but the present invention is not limited to this configuration. Moreover, although the motor is used for each of the 1st ventilation means 27 and the 2nd ventilation means 28a and 28b, it is set as the structure which rotates 2 units | sets or 3 units | sets, sharing one motor. Is also possible. In addition, regarding the installation positions of the first blower means 27 and the second blower means 28a, 28b, as long as the air in the drying chamber 10 or the air outside the drying chamber 10 can be blown in a predetermined direction in each air passage. There is no particular limitation.
[0040]
  (Example 4)
  Next, a fourth embodiment of the present invention will be described. FIG. 6 is a cross-sectional view showing the configuration of this embodiment. Portions common to the above-described embodiments are given the same numbers, and descriptions thereof are omitted. In the present embodiment, the air sucked from the upper part of the drying chamber 10 through the circulation air passage 25 by the first blowing means 27 is dehumidified by the adsorbent 24 and is blown and circulated to the lower part of the drying chamber 10. In addition, a heat exchanger 31, a heating unit 29, and an adsorbent 24 are disposed in the regeneration air passage 26.
[0041]
  The air sucked by the second air blowing means 45 from the air inlet 45a opened to the outside of the drying chamber 10 is blown by the heat exchanger 31 into the regeneration air passage 26 side and the cooling air passage 44 side. The regeneration air on the regeneration air passage 26 side that has passed through the heat exchanger 31 is exhausted from an exhaust port 31 a that opens to the outside air via the heating means 29, the adsorbent 24, and the heat exchanger 31. On the other hand, the cooling air sucked from the air inlet 45a by the second air blowing means 45 and passed through the cooling air passage 44 is blown to the heat exchanger 31 and is heat-exchanged with the regenerated air by the heat exchanger 31, and then the air outlet 31a. To the outside of the drying chamber 10. Reference numeral 32 denotes control means for controlling each means. Reference numeral 34 denotes a drain hole provided in the regeneration air passage 26 for discharging condensed water generated in the heat exchanger 31.
[0042]
  The operation of this embodiment will be described below. When the user operates an operation unit (not shown) and starts operation, the control unit 32 activates the first blowing unit 27, the second blowing unit 45, the heating unit 29, and the rotor motor 36. The air in the drying chamber 10 circulates through the circulation air passage 25 and the adsorbent 24 by the first air blowing means 27. The air that has passed through the adsorbent 24 is dehumidified by adsorbing moisture to the adsorbent 24 to obtain heat of adsorption to become high-temperature and low-humidity dry air. Drying proceeds in the drying chamber 10 by the circulation of the dry air. At the same time, the second air blowing means 45 separately blows air as regenerated air and cooling air to the air regenerating air passage 26 and the cooling air passage 44 sucked from the air inlet 45a opened outside the drying chamber 10, respectively. The regeneration air passes through the heat exchanger 31 and is sent to the heating means 29. The air heated to a high temperature by energization of the heating means 29 passes through the regeneration zone 41 of the adsorbent 24 and releases the moisture absorbed by the adsorbent 24. Regenerated air containing moisture generated by regeneration and having become highly humid is exhausted from the exhaust port 31 a through the heat exchanger 31. While passing through the heat exchanger 31, the new regeneration air taken in by the second air blowing means 45 is heated. In other words, the heat energy of the regeneration air is supplied to new regeneration air sucked from the intake port 45a by heat exchange. Therefore, also in the present embodiment, the humid and relatively high-temperature regeneration air after passing through the regeneration zone 41 of the adsorbent 24 passes through the adsorbent 24 and the heating means 29 using the heat exchanger 31. The heat energy of the regeneration air can be recovered by exchanging heat with the air outside the previous relatively low temperature drying chamber 10. At this time, according to the present embodiment, the regenerated small amount of regenerated air is further cooled by the heat exchanger 31 by the large amount of cooling air outside the drying chamber 10 sucked by the second air blowing means 45. . For this reason, the regeneration air condenses to release moisture, becomes low humidity, and is exhausted from the exhaust port 31a. Therefore, according to the present embodiment, the humidity outside the drying chamber 10 is not increased by the exhaust air. The condensed water generated at this time is drained out of the system through a drain hole 34 provided in the regeneration air passage 26.
[0043]
  In this embodiment, a single heat exchanger 31 is used to exchange heat between the regenerated air that has passed through the adsorbent 24 and new regenerated air or cooling air that has been sucked from the air intake 45a. is there. At this time, the intake air is partitioned into the regeneration air passage 26 side and the cooling air passage 44 side. For this reason, the effect equivalent to the case where two heat exchangers are used with one heat exchanger 31 can be obtained, and the number of heat exchangers can be reduced.
[0044]
  Further, in this embodiment, one second air blowing means 45 is used and the air volume necessary for the regeneration air and the cooling air is obtained by partitioning the inside. For this reason, even if it is the one 2nd ventilation means 45, the effect equivalent to the case where two 2nd ventilation means are used is acquired, and a number of parts can be reduced.
[0045]
  In this embodiment, a motor and a centrifugal sirocco fan are used as the second air blowing means 45, but the present invention is not limited to this configuration. Moreover, although the motor is used for each of the 1st ventilation means 27 and the 2nd ventilation means 45, it is also possible to set it as the structure which rotates 2 units | sets of fans by sharing one motor. Further, the installation positions of the first air blowing means 27 and the second air blowing means 45 are also particularly limited as long as the air inside the drying chamber 10 or the air outside the drying chamber 10 can be blown in a predetermined direction in each air passage. Not what you want.
