Description
- 1. Field of the Invention
- The present invention relates to a humidity adjusting apparatus using a desiccant, which can easily adjust humidifying and dehumidifying volumes, and more particularly, to a humidity adjusting apparatus that can easily increase an amount of a desiccant used for increasing or decreasing the humidity in a limited space.
- 2. Description of the Related Art
- Generally, a humidity adjusting apparatus uses a desiccant to increase or decrease the humidity in a room or other enclosure.
- The desiccant is a substance that has a high affinity for water and is used as a drying agent. When the desiccant absorbing water is heated, the affinity for water is restored. Therefore, the desiccant can be reused. In addition, the desiccant is designed to absorb moisture in air when surface vapor pressure is less than partial pressure of ambient air and to discharge moisture when the surface vapor pressure is less than the partial pressure of the ambient air.
- U.S. Pat. No. 5,148,374 discloses such a humidity adjusting apparatus using a desiccant. The humidity adjusting apparatus disclosed in the patent has a desiccant wheel in which the desiccant is received. The desiccant wheel is designed to periodically rotate to absorb and discharge moisture from and to air being introduced.
- However, the desiccant wheel is formed of a tow-dimensional circular or semi-circular flat plate that two-dimensionally rotates. In order to use the humidity adjusting apparatus in a high humid region, the humidifying or dehumidifying capability should be enhanced. Therefore, to enhance the capability, the size of the desiccant wheel should be increased. In this case, since the desiccant wheel is formed in a two-dimensional plate, an area occupied by the desiccant wheel is enlarged, increasing a whole size of the dehumidifier.
- Due to this structural problem, more than two dehumidifiers or a large-sized dehumidifier should be installed in an enclosed room.
- Accordingly, the present invention is directed to a desiccant humidifier that substantially obviates one or more problems due to limitations and disadvantages of the related art.
- An object of the present invention is to provide a humidity adjusting apparatus that is enhanced in a humidifying/dehumidifying volume variation.
- Another object of the present invention is to provide a humidity adjusting apparatus that can easily vary the volume without varying an overall size and a shape.
- Still another object of the present invention is to provide a humidity adjusting apparatus that is enhanced in its humidifying and dehumidifying capability without increasing the size thereof.
- Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
- To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, there is provided a humidity adjusting apparatus including: a fan for forcedly generating airflow; a heater for heating introduced air to a predetermined temperature; a driving unit for generating driving force; and a desiccant unit having a rotational shaft driven by the driving unit and a plurality of desiccant plates supported on the rotational shaft in a radial direction, an orientation of each desiccant plate and airflow direction being periodically varied.
- In another aspect of the present invention, there is provided a humidity adjusting apparatus including: a driving unit for generating driving force; a rotational shaft driven by the driving unit and inclined at a predetermined angle with respect to an airflow direction in the apparatus; and at least one desiccant plate supported on the rotational shaft in a radial direction.
- In still another aspect of the present invention, there is provided a humidity adjusting apparatus including: a rotational shaft inclined with respect to an airflow direction; and at least one desiccant plate extending from the rotational shaft in a radial direction, an angle between the desiccant plate and the airflow direction being periodically varied.
- According to the present invention, since the desiccant plates are disposed on the rotational shaft in a radial direction, a number of desiccant plates can be received in a limited space, thereby increasing the volume of the desiccant.
- It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

-
FIG. 1 shows a perspective view of a humidity adjusting apparatus according to a first embodiment of the present invention. - Referring to
FIG. 1 , a humidity adjusting apparatus 1 includes adesiccant unit 2 for absorbing or discharging moisture from or to air. - The humidity adjusting apparatus 1 includes a
rotational shaft 3, a desiccant extendingportion 4, and a driving unit mounting portion 6 where therotational shaft 3 is coupled to a driving unit 6. Thedesiccant unit 2 periodically rotates by the driving unit 6. - The
rotational shaft 3 is disposed having a predetermined angle with respect to an airflow passage defined in the apparatus 1 such that an area of a desiccant contacting the air can be increased in a limited space. Therefore, it becomes possible to increase a volume of the desiccant without increasing the size of the apparatus 1. To realize this effect, it is preferable that therotational shaft 3 is disposed to be perpendicular to the airflow passage. - The
desiccant unit 2 further includes first, second, third, and fourthdesiccant plates desiccant plate 7 has first front andrear surfaces desiccant plate 10 has second front andrear surfaces desiccant plate 13 has third front andrear surfaces desiccant plate 16 has fourth front andrear surfaces desiccant plates desiccant plates desiccant plates - Although four desiccant plates are provided in this embodiment, the present invention is not limited to this case. That is, the number of desiccant plates can be varied in accordance with the required dehumidifying/humidifying volume/
- A projected shape of each desiccant plate in a normal direction of the desiccant plate can be formed in a variety of shapes such as a rectangular shape, a circular shape, and the like. However, in the light of an object of the present invention for easily increasing the humidifying/dehumidifying volume, it may be preferable that the projected shape is the rectangular shape.
- In addition, an area of each desiccant plate is designed having a predetermined area to receive much more desiccant in the limited space.
- The humidity adjusting apparatus 1 further includes an intake fan for introducing the air into the apparatus 1 and an
exhaust fan 32 for exhausting the air out of the apparatus 1. The intake and exhaust fans are disposed at opposite sides with reference to thedesiccant unit 2. - The
intake fan 27 is provided with anair inlet 28 for introducing air and anair outlet 29 for exhausting the introduced air passing through thedesiccant unit 2. Theexhaust fan 32 is also provided with anair inlet 33 and anair outlet 34. - An air intake passage is defined between the
desiccant unit 2 and theintake fan 27, and an airdry passage 31 is defined between thedesiccant unit 2 and theair exhaust fan 32. - The humidity adjusting apparatus 1 further includes a
heater 19 and an intake/exhaust fan 23 disposed at an opposite side of theheater 19 with reference to thedesiccant unit 2. Theheater 19 heats air introduced through the intake/exhaust fan 23 to a predetermined temperature. - The
heater 19 includes aheater case 20, a heat source formed in theheater case 20 and agrill 21. - The intake/
exhaust fan 23 is provided with anair inlet 24 and anair outlet 25. - A high
temperature air passage 22 is defined between thedesiccant unit 2 and theheater 19, and awet air passage 26 is defined between thedesiccant unit 2 and the intake/exhaust fan 23. - As the airflow direction of the air introduced into the apparatus 1 is at a predetermined angle (about 90°) with respect to an airflow direction to the
desiccant unit 2, the intake and/or exhaust fan(s) 27 and/or 32 may be formed of a Sirocco fan or a turbo fan. - The operation of the above-described humidity adjusting apparatus will be described hereinafter.
- When the apparatus is turned on, the
intake fan 27 is operated to introduce air through theair inlet 28 and theair outlet 29. - In this embodiment, since the
intake fan 27 is formed of one of the Sirocco and turbo fans, the introduced air changes its flow direction to reach thedesiccant unit 2 along theair intake passage 30. - The air directed to the
desiccant unit 2 comes in thethird desiccant plate 13 through the thirdfront surface 14 and comes out of the same through the thirdrear surface 15. - At this point, since the
third desiccant plate 13 is in a dry state, the moisture contained in the introduced air is absorbed in thethird desiccant plate 13. Then, the introduced air is altered into dry air. - Here, in order to increase a moisture absorption rate of the
third desiccant plate 13, the airflow passage is formed such that the air passes thethird desiccant plate 13 in a perpendicular direction while rotating thedesiccant plate 13. This feature is identically applied to other desiccant plates. - The dry air reaches the
exhaust fan 32 along thedry air passage 31. Then, the dry air is exhausted out of the apparatus 1 through theair outlet 34 of theexhaust fan 32. - The
third desiccant plate 13 absorbing the moisture rotates by the driving unit 6 by a predetermined angle (about 180°) so that thethird desiccant plate 13 can be replaced to a location where thefirst desiccant plate 7 has been located, which is to be displaced to a location where thethird desiccant plate 7 has been located. That is, the locations of the first andthird desiccant plates - That is, an angle between a disposing direction of the desiccant plate, i.e., a normal direction of the desiccant plate, and an airflow direction in the apparatus is periodically varied. Namely, since the
rotational shaft 3 periodically rotates, the location of the desiccant plates coupled to the rotational shaft is varied within a range of 0-180°. - When the intake/
exhaust fan 23 is operated, high temperature air is introduced through theheat 19. This high temperature air is directed to thedesiccant unit 2 along thehigh temperature passage 22. - The high temperature air passes through the
third desiccant plate 13 containing the moisture, during which the moisture contained in thethird desiccant plate 13 is vaporized to make the air wet air. - The wet air is directed to the intake/
exhaust fan 23 through thewet air passage 26 and exhausted through theair outlet 25. - Here, when the
intake fan 27 is connected to the outdoor side and theexhaust fan 32 is connected to the indoor side, the humidity adjusting apparatus 1 functions as a dehumidifier. When theintake fan 27 is connected to the indoor side and theexhaust fan 32 is connected to the outdoor side, the humidity adjusting apparatus 1 functions as a humidifier. - The location displacement of the desiccant plates of the
desiccant unit 2 is continuously realized at a predetermined period. - As the
desiccant unit 2 continuously rotates, thethird desiccant plate 13 is displaced to a location where thesecond desiccant plate 10 has been located after absorbing the moisture. Then, thefourth desiccant plate 16 is located between theair intake passage 30 and thedry air passage 31 to function to absorb the moisture contained in the air. - After the above, the
third desiccant plate 13 is located between thehigh temperature passage 22 and thewet air passage 26 to release the moisture, after which thefourth desiccant plate 16 containing the moisture is displaced to the location between the high temperature passage and thewet air passage 26 to discharge the moisture. - Then, the
third desiccant plate 13 is again displaced to the location between theintake passage 30 and thedry air passage 31 to absorb the moisture. - The above-described process is continuously repeated so that the apparatus 1 can perform the humidifying/dehumidifying function.
-
FIG. 2 shows the desiccant unit depicted inFIG. 1 . - Referring to
FIG. 2 , the first throughfourth desiccant plates desiccant extending portion 4 of therotational shaft 3 to rotate against the airflow direction. Theintake passage 30 and thewet air passage 26 are separated by abarrier wall 36 while the dry air passage and thehigh temperature passage 22 are separated by abarrier wall 35. - At least one of the first through
fourth desiccant plates desiccant extending portion 4 in a radial direction so that the introduced airflow direction can be perpendicular to thereof. Accordingly, the moisture absorption/discharge efficiency for the introduced air can be enhanced. - In addition, since the first through
fourth desiccant plates -
FIGS. 3 and 4 show a desiccant unit of a humidity adjusting apparatus according to a second embodiment of the present invention. - In this embodiment, a description of parts identical to those of the first embodiment will be omitted.
- Referring to
FIGS. 3 and 4 , each of first tofourth desiccant plates desiccant extending portion 4, having at least one bent portion. - In this embodiment, each desiccant plate has first, second and third
bent portions bent surfaces bent portions - As each of the first to
fourth desiccant plates -
FIGS. 5 and 6 show a desiccant unit of a humidity adjusting apparatus according to a third embodiment of the present invention. - Referring to
FIGS. 3 and 4 , first tofourth desiccant plates desiccant extending portion 4, each being formed in a non-planar plate having a plurality of valleys and ridges defining at least one wave. - In this embodiment, each desiccant plate has first and
second waves -
FIG. 7 shows a humidity adjusting apparatus according to a fourth embodiment of the present invention. - A humidity adjusting apparatus according to this embodiment includes an
axial fan 54. - As the
axial fan 54 is employed to the apparatus 1, an airflow direction in the apparatus becomes identical to that of airflow generated by theaxial fan 54. -
FIG. 8 shows a humidity adjusting apparatus according to a fifth embodiment of the present invention. - A humidity adjusting apparatus according to this embodiment includes a
cross flow fan 55. - As the
cross flow fan 55 is employed to the apparatus 1, an airflow direction in the apparatus is inclined to that of airflow generated by thecross flow fan 54 at a predetermined angle. - The fourth and fifth embodiment show that the humidity adjusting apparatus can provide a variety of air passages by employing a variety of fans in accordance with a variety of conditions such as an install location and the like.
- The desiccant plates may be designed having an identical thickness to each other to provide an identical dehumidifying/humidifying volume. However, the present invention is not limited to this case. That is, if required, the thickness of the desiccant plates can be different from each other.
- Since there may be an airflow rate difference according to a location, the thickness of the desiccant plates can be varied according to the airflow rate difference to optimize the humidifying/dehumidifying efficiency.
- Meanwhile, the shape of the desiccant plate is not limited to the above-described embodiments. The shape of the desiccant plate can be varied according to a variety of ambient conditions.
- According to the present invention, since the desiccant plates are disposed on the rotational shaft in a radial direction, a number of desiccant plates can be received in a limited space, thereby increasing the volume of the desiccant.
- In addition, since the rotational shaft supporting the desiccant plates is at a predetermined angle with respect to the airflow passage formed in the apparatus, much more desiccant can be received in a limited space.
- Furthermore, by providing the desiccant plates each having at least one bent portion or wave, an amount of the desiccant can be further increased, thereby increasing the humidifying/dehumidifying volume of the apparatus.
- In addition, since a variety of fans such as a turbo fan, a Sirocco fan, an axial fan, and a cross flow fan can be employed, the humidity adjusting apparatus can provide a variety of air passages by employing a variety of fans in accordance with a variety of conditions such as an install location and the like.
- It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
