Definitions
- the present invention relates to a dehumidifier for dehumidifying indoor air and, more particularly, to a dehumidifier having a dehumidifying rotor that absorbs moisture from the indoor air and is regenerated at low temperature.
- a dehumidifier dehumidifies humid indoor air and, conventionally, the dehumidifier allows the indoor air to pass through a heat exchanger including a condenser in which refrigerant flows and an evaporator to reduce the humidity and discharges the dehumidified air to the room, thus reducing the indoor humidity.
- the dehumidifier absorbs heat from ambient air by evaporating the refrigerant in the evaporator.
- the temperature of the evaporator is reduced, and thus the temperature of the air passing through the evaporator is also reduced.
- the moisture contained in the air is condensed into dew on the surface of the evaporator, and the dew on the surface of the evaporator falls into a bucket.
- the above-described dehumidifier using the heat exchanger including the condenser and the evaporator is problematic in that it requires a compressor for compressing the refrigerant, the manufacturing cost is increased, noise is generated according to the operation of the compressor, it requires a space in which the compressor is located, the volume of the dehumidifier is increased, and thus it cannot be easily moved due to the weight of the compressor.

heat exchanger 110 includes a condensingflow passage 112, through which the regeneration air (O) that has regenerated thedehumidifying rotor 60 passes, and a heat-absorbingflow passage 114, through which the indoor air (I) sucked by theblower 50 and introduced into theblower 50 passes before it passes through the dehumidifyingrotor 60. - A plurality of condensing
heat exchangers 110 are disposed in the flow direction of the indoor air (I). - The condensing
flow passage 112 is provided in the condensingheat exchanger 110, and the heat-absorbingflow passage 114 penetrates the condensingheat exchanger 110. - The condensing
flow passage 112 is provided between front and rear plates of the condensingheat exchanger 110, and the front and rear plates are formed of a synthetic resin material to facilitate the molding of the condensingflow passage 112 and the heat-absorbingflow passage 114 and reduce the weight thereof. - The condensing
flow passage 112 includes a plurality of flow passages connected in parallel in the condensingheat exchanger 110, and each of the plurality of flow passages is arranged in the condensingheat exchanger 110 in the up and down direction. - The heat-absorbing
flow passage 114 is formed at positions, where the flow passages of the condensingflow passage 112 are not formed, in the condensingheat exchanger 110 in the front and rear direction. - The heat-absorbing
flow passage 114 is formed between the flow passages of the condensingflow passage 112 to penetrate the condensingheat exchanger 110 in a direction intersecting the condensingflow passage 112. - That is, the condensing
flow passage 112 of the condensingheat exchanger 110 is divided into a plurality of flow passages by the heat-absorbingflow passage 114. When the regeneration air (O) moves in the up and down direction through the condensingflow passage 112 in the condensingheat exchanger 110, the indoor air (I) passes through the heat-absorbingflow passage 114 at the front of the condensingheat exchanger 110 in the front and rear direction to condense the regeneration air (O), and then moves to the rear of the heat-absorbingflow passage 114. - The condensing
heat exchanger 110 includes a regeneration air inlet port formed at the top, through which the regeneration air (O) passing through the dehumidifyingrotor 60 is introduced into the condensingheat exchanger 110, a regenerationair discharge port 116 formed at the bottom, through which the regeneration air (O) passing through the condensingflow passage 112 is discharged, and a condensedwater discharge port 118 through which water condensed in the condensingflow passage 112 is discharged. - The generation air inlet port of the condensing
heat exchanger 110 has substantially the same size and shape as the regeneration portion of thedehumidifying rotor 60. - When the
regeneration heater 100 has an angular shape, the portion of thedehumidifying rotor 60 facing theregeneration heater 100 corresponds to the regeneration portion, and the regeneration air inlet port of the condensingheat exchanger 110 has the same angular shape as theregeneration heater 100. - On the contrary, when the
regeneration heater 100 has a semicircular shape, the portion of thedehumidifying rotor 60 facing theregeneration heater 100 corresponds to the regeneration portion, and the regeneration air inlet port of the condensingheat exchanger 110 has the same semicircular shape as theregeneration heater 100. - The regeneration
air discharge port 116 of the condensingheat exchanger 110 is formed to project from one side of the circumference of the condensingheat exchanger 110 such that the heat exchange region of the condensingheat exchanger 110 is maximized. - That is, when the regeneration
air discharge port 116 is located on the front and rear surfaces of the condensingheat exchanger 110, i.e., on the air flow surface, the heat exchange region of the condensingheat exchanger 110 is reduced by the space that the regenerationair discharge port 116 occupies. Therefore, if the regenerationair discharge port 116 is formed to project from the side of the circumference of the condensingheat exchanger 110 in the above manner, the heat exchange region of the condensingheat exchanger 110 is increased. - Meanwhile, the condensed
water discharge port 118 is formed to project from the bottom of the circumference of the condensingheat exchanger 110. - Since the respective flow passages of the condensing
flow passage 112 are formed to be spaced apart from one another in the left and right direction of the condensingheat exchanger 110, it is preferable that the condensedwater discharge port 118 be formed at the bottom, especially in the middle of the bottom, of the circumference of the condensingheat exchanger 110. Here, the bottom of the circumference of the condensingheat exchanger 110 is formed to be inclined toward the condensedwater discharge port 118. - The
duct 120 guides the air passing through the condensingflow passage 112 of the condensingheat exchanger 110 to theregeneration fan 90 such that a regeneration flow passage through which the regeneration air (O) passes in the dehumidifier forms a closed circuit. One end of theduct 120 is connected to the regenerationair discharge port 116 and the other end is connected to the openingportion 76 of therotor frame 69. - That is, in the dehumidifier in accordance with the preferred embodiment, the
regeneration fan 90, theregeneration heater 100, the dehumidifyingrotor 60, the condensingheat exchanger 110, and theduct 120 are sequentially arranged in this order in the flow direction of the indoor air (I).

regeneration fan 90 sequentially passes through theregeneration heater 100 and thedehumidifying rotor 60, moves to the front of thedehumidifying rotor 60, moves downward in front of thedehumidifying rotor 60 along the condensingflow passage 112 of the condensingheat exchanger 110, moves to the side of the condensingheat exchanger 110, moves to the front top of therotor frame 69 along theduct 120, passes through therotor frame 69 in the front and rear direction to be moved to the rear thereof, and is then introduced into theregeneration fan 90. - The dehumidifier having the dehumidifying rotor in accordance with the preferred embodiment further includes the
bucket 130 and adrain fan 140. - The
bucket 130, into which the condensed water generated in a condensingheat exchanger 110 falls, is formed in a box shape with an opened top. - The
bucket 130 is inserted into the bottom of thedrain fan 140 through the openingportions rear case 20 and thefront case 30 of themain body 2 or extracted to the outside. - The
drain fan 140 receives the condensed water falling from the condensingflow passage 112 of the condensingheat exchanger 110 to be put into thebucket 130, and is located in themain body 2, especially at the bottom of the condensingheat exchanger 110. -

rotor supporter 68 supports thedesiccant 61 and thedesiccant wheel 62 and is integrally assembled with theregeneration heater 100. - The fixing
portion 65 of thedesiccant wheel 62 is inserted into the fixinghole 63 formed in the middle of thedesiccant 61 and fixed with thedesiccant 61. The fixingportion 65 serves as a rotation axis of thedehumidifying rotor 60, and a supportaxis penetration hole 67 at which thesupport axis 71 of therotor supporter 68 penetrates is provided. - The
support axis 71 of therotor supporter 68 projects to penetrate the supportaxis penetration hole 67 of thedehumidifying rotor 60. - The
support axis 71 of therotor supporter 68 includes afastening hole 74 to which afastening member 104 is fastened such that theregeneration heater 100 is fixed to thesupport axis 71. - The

FIG. 8 is a front view of the dehumidifying rotor and the rotor frame shown inFIG. 2 . - As shown in FIOG. 8, the dehumidifier in accordance with the preferred embodiment of the present invention further includes a dehumidifying
rotor rotating device 84 rotating thedehumidifying rotor 60. - The dehumidifying
rotor 60 includes a drivengear 85 provided on the outer circumference of thecircumferential portion 64 of thedesiccant wheel 62. - The dehumidifying
rotor rotating device 84 rotates thedesiccant wheel 62 of thedehumidifying rotor 60 and includes adriving gear 86 rotating the drivengear 85 and amotor 87 rotating thedriving gear 86. - The
motor 87 is fastened to one of therotor supporter 68 and therotor frame 69 by a fastening member such as a screw. - The
motor 87 is disposed such that thedriving gear 86 is located on one side of the circumference of the drivengear 86. - The operation of the dehumidifier having the above-described structure in accordance with the present invention will be described below.
- First, when a command for operating the dehumidifier is input through the
control unit 36, thecontroller 78 operates theblower 50 as the dehumidifying fan, theregeneration fan 90, and the dehumidifyingrotor rotating device 84. - During operation of the dehumidifying
fan 50, the indoor air (I) sucked into themain body 2 through theair suction portion 4 passes through the heat-absorbingflow passage 114 of the condensingheat exchanger 110 and then passes through the dehumidifyingrotor 60. Moisture of the indoor air (I) passing through the dehumidifyingrotor 60 is absorbed by thedesiccant 61, and thus the temperature of the indoor air (I) is increased. Then, the resulting indoor air (I) is discharged to the outside through the air discharge portion 6 (A→B→C→D). - Meanwhile, during the operation of the dehumidifying
fan 50, the dehumidifyingrotor rotating device 84 rotates the dehumidifyingrotor 60. The portion of thedehumidifying rotor 60 to which the moisture is adsorbed while the indoor air (I) passes therethrough, i.e., the dehumidification portion, becomes the regeneration portion as it faces theregeneration heater 100, and is then returned to the dehumidification portion as it moves to the position, which does not face theregeneration heater 100. - During operation of the
regeneration fan 90, the regeneration air (O) is moved to theregeneration heater 100 by theregeneration fan 90 and is heated to a high temperature by theregeneration heater 100. Subsequently, the regeneration air (O) heated to a high temperature by theregeneration heater 100 passes through the regeneration portion, which corresponds to the portion of thedehumidifying rotor 60 facing theregeneration heater 100, such that the moisture adsorbed to the regeneration portion of thedehumidifying rotor 60 is evaporated, and thus the regeneration air (O) becomes high temperature and high humidity air. Then, the high temperature and high humidity regeneration air (O) changed by the dehumidifyingrotor 60 is introduced and passes through the condensingflow passage 112 of the condensingheat exchanger 110 such that the indoor air (I) passing through the condensingheat exchanger 110 absorbs the heat of the regeneration air (O), and thus the moisture is condensed as the temperature of the regeneration air (O) is reduced (E→F→G→H). - The regeneration air (O) passing through the condensing
flow passage 112 passes through theduct 120 and is sucked into theregeneration fan 90. As such, the regeneration air (O) circulates theregeneration fan 90, theregeneration heater 100, the dehumidifyingrotor 60, the condensingheat exchanger 110, and theduct 120 to continuously regenerate thedehumidifying rotor 60. - During the dehumidification of the indoor air and during the regeneration of the
dehumidifying rotor 60, the condensed water is generated in the condensingflow passage 112 of the condensingheat exchanger 110 and falls down. The falling condensed water falls down to thedrain fan 140 through the condensedwater discharge port 118 of the condensingheat exchanger 110 and is then put into thebucket 130. - Meanwhile, according to the above-described dehumidifier, since the
desiccant 61 of thedehumidifying rotor 60 contains the meso-silica, it is possible to regenerate thedesiccant 61 at low temperature. Therefore, it is not necessary to increase the temperature of theregeneration heater 100 to a high temperature, it is possible to minimize the power consumption of theregeneration heater 100, and it is possible to increase the dehumidification capacity per unit time since thedesiccant 61 is rapidly regenerated. - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. 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.
