FIGS. 1 and 2 , the conventional humidifier includes abody 2, and adesiccant wheel 6 arranged in the interior of thebody 2, and adapted to perform absorption of moisture and release of the absorbed moisture. - A
barrier 4 is mounted in the interior of thebody 2 to partition the interior of thebody 2 into anabsorption chamber 10, in which absorption of moisture from air introduced into theabsorption chamber 10 is carried out, and aregeneration chamber 20, in which release of moisture to air introduced into theregeneration chamber 20 is carried out. - The
desiccant wheel 6 is mounted to thebarrier 4 in a state of being inclined at a predetermined angle while extending through thebarrier 4 such that one portion of thedesiccant wheel 6 is positioned in theabsorption chamber 10, and the other portion of thedesiccant wheel 6 is positioned in theregeneration chamber 20. A rotator (not shown) such as a motor is coupled to thedesiccant wheel 6, in order to turn thedesiccant wheel 6 such that the positions of the portions of thedesiccant wheel 6 are reversed, after thedesiccant wheel 6 has been used for a predetermined time. - The
absorption chamber 10 is provided with afirst inlet 12, through which ambient air is introduced into theabsorption chamber 10, and afirst outlet 14, through which air dehumidified in theabsorption chamber 10 is outwardly discharged. Theregeneration chamber 20 is provided with asecond inlet 22, through which ambient air is introduced into theregeneration chamber 20, and asecond outlet 24, through which air humidified in theregeneration chamber 20 is discharged into the room. - The
first inlet 12 is formed at a rear wall of thebody 2. Thefirst outlet 14 andsecond inlet 22 are formed at a front wall of thebody 2. Thesecond outlet 24 is formed at one side wall of thebody 2. - A first blowing
fan 16 is arranged in theabsorption chamber 10, to generate a blowing force for sucking ambient air into theabsorption chamber 10 through thefirst inlet 12, and outwardly discharging the sucked air through thefirst outlet 14. A second blowingfan 26 is arranged in theregeneration chamber 20, to generate a blowing force for sucking ambient air into theregeneration chamber 20 through thesecond inlet 22, and discharging the sucked air into the room through thesecond outlet 24. - A
first flow guide 18 is arranged in theabsorption chamber 10. Thefirst flow guide 18 partitions theabsorption chamber 10 into a suction chamber portion where thefirst inlet 12 is arranged and a discharge chamber portion where thefirst outlet 14 is arranged, to guide ambient air sucked into theabsorption chamber 10 through thefirst inlet 12 to be outwardly discharged through thefirst outlet 14 after passing through thedesiccant wheel 6. - A
second flow guide 28 is arranged in theregeneration chamber 20. Thesecond flow guide 28 partitions theregeneration chamber 20 into a suction chamber portion where thesecond inlet 22 is arranged and a discharge chamber portion where thesecond outlet 24 is arranged, to guide ambient air sucked into theregeneration chamber 20 through thesecond inlet 12 to be discharged into the room through thesecond outlet 24 after passing through thedesiccant wheel 6. - A
heater 30 is arranged in theregeneration chamber 20, to heat the air sucked into theregeneration chamber 20 through thesecond inlet 22. - Meanwhile, a
third flow guide 7 is arranged in the suction chamber portion of theregeneration chamber 20, to define acooling chamber portion 8 in which one portion of thedesiccant wheel 6 heated in theregeneration chamber 20 is cooled by the air sucked into theregeneration chamber 20 before being turned toward theabsorption chamber 10. - Hereinafter, operation of the conventional humidifier having the above-mentioned configuration will be described.
- First, when the first blowing
fan 16 in theabsorption chamber 10 operates, ambient air is sucked into theabsorption chamber 10 through thefirst inlet 12, to pass thedesiccant wheel 6. Moisture contained in the sucked air is absorbed into thedesiccant wheel 6 while the sucked air passes thedesiccant wheel 6, so that the sucked air is dehumidified. - The air dehumidified by the
desiccant wheel 6 is then outwardly discharged from theabsorption chamber 10 through thefirst outlet 14. - Meanwhile, when the second blowing
fan 26 in theregeneration chamber 20 operates, ambient air is sucked into theregeneration chamber 20 through thesecond inlet 22, and is then heated by theheater 30. The heated air then dries thedesiccant wheel 6 while passing through thedesiccant wheel 6. - As the
desiccant wheel 6 is dried by the heated air, moisture is released from thedesiccant wheel 6 to the air. That is, the air is humidified by thedesiccant wheel 6. The humidified air is then discharged into the room through thesecond outlet 24. - However, since the conventional humidifier heats ambient air sucked into the
regeneration chamber 20 to a predetermined temperature or above, in order to more effectively release moisture from thedesiccant wheel 6, an increased amount of electric power is consumed due to the use of theheater 30, thereby resulting in an increase in maintenance costs. - The present invention has been made in view of the above-described related art, and it is an object to provide a humidifier capable of reducing the load of a heater used in the humidifier, and thus, achieving a reduction in power consumption.
- In accordance with the present invention, this object is accomplished by providing a humidifier comprising: a body; a barrier which partitions the interior of the body into an absorption chamber and a regeneration chamber; a turnable desiccant wheel arranged in the interior of the body while extending through the barrier such that one portion of the desiccant wheel is arranged in the absorption chamber, to perform absorption of moisture, and the other portion of the desiccant wheel is arranged in the regeneration chamber, to perform release of moisture; a heater arranged in the regeneration chamber, and adapted to heat ambient air introduced into the regeneration chamber; and a heat exchanger arranged at an inlet side of the regeneration chamber, and adapted to heat-exchange the air introduced into the regeneration chamber with air dehumidified in the absorption chamber.

- The at least one channel may comprise a plurality of uniformly-spaced channels.
- The heat exchanger and the heater may be arranged at opposite sides of the desiccant wheel, respectively.
- The humidifier may further comprise a cooler arranged at the inlet side of the regeneration chamber, and adapted to cool the portion of the desiccant wheel dehumidified in the regeneration chamber before being turned toward the absorption chamber, using the air introduced into the regeneration chamber.
- The heat exchanger may be arranged in the cooler.
- The humidifier may further comprise an absorption-side blowing fan for generating a blowing force to suck ambient air into the absorption chamber, and to outwardly discharge the sucked air, and a regeneration-side blowing fan for generating a blowing force to suck ambient air into the regeneration chamber, and to outwardly discharge the sucked air.
- The absorption-side blowing fan may be arranged in an absorption-side blowing chamber defined in the interior of the body at an outlet side of the heat exchanger to outwardly discharge air emerging from the heat exchanger.
- The regeneration-side blowing fan may be arranged in a regeneration-side blowing chamber defined in the interior of the body at an outlet side of the regeneration chamber to outwardly discharge air humidified in the regeneration chamber.
- The absorption-side blowing fan and the regeneration-side blowing fan may be arranged at upper and lower positions in the interior of the body, respectively.

The humidifier also includes aheater 56 arranged in theregeneration chamber 70, and adapted to heat ambient air introduced into theregeneration chamber 70, and a heat exchanger arranged at an inlet side of theregeneration chamber 70, and adapted to heat-exchange the air introduced into theregeneration chamber 70 with air dehumidified in theabsorption chamber 60. - The
desiccant wheel 54 is mounted to thebarrier 52 in the interior of thebody 50 in a state of being inclined at a predetermined angle while extending through thebarrier 52 such that one portion of thedesiccant wheel 54 is positioned in theabsorption chamber 60, and the other portion of thedesiccant wheel 54 is positioned in theregeneration chamber 70. - The portion of the
desiccant wheel 54 positioned in theabsorption chamber 60 functions to absorb moisture from air passing through theabsorption chamber 60, whereas the portion of thedesiccant wheel 54 positioned in theregeneration chamber 70 functions to release moisture from air passing through theregeneration chamber 70. - After being used for a predetermined time, the
desiccant wheel 54 is turned by the rotator (not shown), in order to enable the desiccant wheel portion humidified in theabsorption chamber 60 to be regenerated in theregeneration chamber 70. For the rotator, a motor may be used which includes a rotating shaft axially coupled to a rotation center of thedesiccant wheel 54. Alternatively, a motor may be used which is connected to thedesiccant wheel 54 via a belt wound around thedesiccant wheel 54. - The
absorption chamber 60 is provided with an absorption-side inlet 62, through which ambient air is introduced into theabsorption chamber 60. Also, theregeneration chamber 70 is provided with a regeneration-side inlet 72, through which ambient air is introduced into theregeneration chamber 70. - Meanwhile, a
first flow guide 58 is arranged in a portion of theregeneration chamber 70 where the regeneration-side inlet 72 is arranged, to define a cooling chamber, namely, a cooler 80, in which the portion of thedesiccant wheel 54 dehumidified in theregeneration chamber 70 is cooled by the air introduced into theregeneration chamber 70 before being turned toward theabsorption chamber 60. - The
first flow guide 58 extends horizontally in theregeneration chamber 70 to partition the interior of theregeneration chamber 70 into an upper chamber portion and a lower chamber portion. The lower chamber portion of theregeneration chamber 70, which is arranged in front of the regeneration-side inlet 72, constitutes the cooler 80. The upper chamber portion of theregeneration chamber 70 constitutes a moisture releasing chamber portion where thedesiccant wheel 54 releases moisture to the air emerging from the cooler 80. - Meanwhile, the heat exchanger comprises at least one
channel 82 which is arranged in the cooler 80 while traversing the inlet side of theregeneration chamber 70, and through which the air dehumidified in theabsorption chamber 60 passes. - In the illustrated case, a plurality of uniformly-spaced
channels 82 are arranged in the cooler 80, and guide the air dehumidified in theabsorption chamber 60 to flow across the inlet side of theregeneration chamber 70. - The humidifier further includes an absorption-
side blowing fan 64 for generating a blowing force to suck ambient air into theabsorption chamber 60 through thefirst inlet 62, and to outwardly discharge the sucked air, and a regeneration-side blowing fan 74 for generating a blowing force to suck ambient air into theregeneration chamber 70 through thesecond inlet 72, and to outwardly discharge the sucked air. - For the absorption-
side blowing fan 64 andgeneration blowing fan 74, sirocco fans may be used, respectively. - The absorption-
side blowing fan 64 and regeneration-side blowing fan 74 are arranged in an absorption-side blowing chamber 84 and a regeneration-side blowing chamber 86 defined in lower and upper portions of the interior of thebody 50, respectively. - The absorption-
side blowing chamber 84 is arranged at the outlet side of thechannels 82, whereas the regeneration-side blowing chamber 86 is arranged at the outlet side of theregeneration chamber 70 over the absorption-side blowing chamber 84. - An absorption-
side outlet 66 is provided at the absorption-side blowing chamber 84, in order to outwardly discharge air emerging from thechannels 82. A regeneration-side outlet 76 is provided at the regeneration-side blowing chamber 86, in order to outwardly discharge air humidified in theregeneration chamber 70. - The absorption-
side blowing chamber 84 and theregeneration chamber 70 are separated from each other by asecond flow guide 78 arranged in the interior of thebody 50. The second flow guide 78 functions to guide the air sucked into the interior of thebody 50 to be outwardly discharged through the regeneration-side outlet 76 after passing through thedesiccant wheel 54. - Operation of the humidifier having the above-described configuration according to the present invention will now be described.
- First, when the absorption-
side blowing fan 64 operates, ambient air is sucked into theabsorption chamber 60 through the absorption-side inlet 62. The sucked air then passes thedesiccant wheel 54. - At this time, the
desiccant wheel 54 absorbs moisture from the air passing through thedesiccant wheel 54 in theabsorption chamber 60, so that the air is dehumidified. During the dehumidification, the air is heated by thedesiccant wheel 54. - The air dehumidified while passing through the
desiccant wheel 54 is introduced into the absorption-side blowing chamber 84 via thechannels 82, and is then outwardly discharged through the absorption-side outlet 66. - Meanwhile, when the regeneration-
side blowing fan 74 operates, ambient air is sucked into the cooler 80 through the regeneration-side inlet 72. The air sucked into the cooler 80 then passes through passages each defined between adjacent ones of thechannels 82. While passing through the passages, the air heat-exchanges with the dehumidified air passing through thechannels 82. - That is, heat from the dehumidified air is transferred to the air sucked into the cooler 80 because the dehumidified air has been heated.
- As a result, the air sucked into the cooler 80 is heated to a certain temperature by the heat received from the dehumidified air. Accordingly, the load of the
heater 56 operating to heat the sucked air to a predetermined temperature is reduced. - The air, which emerges from the cooler 80, is then heated to a predetermined temperature by the
heater 56. The heated air then flows upwards along thedesiccant wheel 54, thereby drying thedesiccant wheel 54. - As the
desiccant wheel 54 is dried, thedesiccant wheel 54 releases moisture to the air passing through thedesiccant wheel 54. The air humidified while passing through thedesiccant wheel 54 is introduced into the regeneration-side blowing chamber 86, and is then discharged to the room through the regeneration-side outlet 76. - Accordingly, the room is humidified because the humidified air is discharged to the room.
- Meanwhile, the
desiccant wheel 54 is turned after a predetermined time elapses, so that the portion of thedesiccant wheel 54 positioned in theregeneration chamber 70 to release moisture passes through the cooler 80, so as to be cooled by the air sucked into the cooler 80 through the regeneration-side inlet 72. The cooled portion of thedesiccant wheel 54 is then positioned in theabsorption chamber 60. - Thus, the function of the
desiccant wheel 54 to absorb moisture from air in theabsorption chamber 60 can be effectively carried out. - The humidifier having the above-described configuration according to the present invention has various effects.
- That is, in accordance with the humidifier of the present invention, the heat of the air dehumidified while passing through the absorption chamber is used to increase the temperature of the air sucked into the regeneration chamber. Accordingly, it is possible to reduce the load of the heater to heat the temperature of the air sucked into the regeneration chamber, and thus, to reduce the power consumption of the heater.
- In addition, since the absorption-side blowing fan and regeneration-side blowing fan are vertically arranged in the interior of the body, respectively, it is possible to reduce the size of the humidifier.
- Although the preferred embodiments of the invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
