Humidity adjusting apparatus using desiccant

Abstract
A humidity adjusting apparatus includes at least one desiccant linearly reciprocated between a dehumidifying unit and a drying unit, and a motor for driving the desiccant to be moved, thereby improving dehumidifying and humidifying efficiency.

Claims

What is claimed is:

1. A humidity adjusting apparatus comprising: a dehumidifier which absorbs moisture contained in air; a dryer which emits moisture into the air so that the air becomes more humid; a barrier wall partitioning the dehumidifier from the dryer; first and second plate-shaped desiccants extending transverse to the barrier wall, the first plate-shaped desiccant having a first surface and the second plate-shaped desiccant having a second surface, the first and second surfaces facing each other; racks provided on the first and second facing surfaces; a pinion engaged with the racks; and a motor coupled to the pinion and configured to drive the first and second desiccants.

2. The humidity adjusting apparatus according to claim 1, wherein the first and second desiccants are provided one above the other in a vertically extending direction of the humidity adjusting apparatus.

3. The humidity adjusting apparatus according to claim 1, wherein the first and second desiccants have a rectangular shape.

4. The humidity adjusting apparatus according to claim 1, further comprising a heater mounted in the dryer.

5. The humidity adjusting apparatus according to claim 1, wherein the motor comprises a step motor.

6. The humidity adjusting apparatus according to claim 1, wherein at least one fan is installed at least at one of the dryer and dehumidifier.

7. The humidity adjusting apparatus according to claim 1, wherein the first and second desiccants have a same shape.

8. The humidity adjusting apparatus according to claim 1, wherein a positioning of the first and second desiccants is configured to shift at predetermined intervals with respect to at least one of the dryer and dehumidifier.

9. A humidity adjusting apparatus, comprising: a barrier wall partitioning an inner space of the apparatus into a dehumidifier and a dryer; a plurality of desiccants configured to move linearly and transverse to the barrier wall; and a motor configured to drive the plurality of desiccants.

10. The humidity adjusting apparatus according to claim 9, wherein at least two of the plurality of desiccants is provided one above the other in a vertically extending direction of the humidity adjusting apparatus.

11. The humidity adjusting apparatus according to claim 9, wherein the desiccants have a same shape.

12. The humidity adjusting apparatus according to claim 9, further comprising: racks provided on oppositely facing surfaces of the desiccants; and a pinion positioned between the racks, the pinion configured to be driven by the motor.

13. The humidity adjusting apparatus according to claim 9, wherein a moving direction of the desiccants is orthogonal to a flow channel of air which passes through the desiccants.

14. The humidity adjusting apparatus according to claim 9, wherein the dryer has an air temperature higher than that of the dehumidifier.

15. The humidity adjusting apparatus according to claim 9, wherein the dryer comprises a heater configured to heat air introduced to the desiccants.

16. The humidity adjusting apparatus according to claim 9, wherein one desiccant is moved in a direction opposite to another desiccant at the same time.

17. A humidity adjusting apparatus, comprising: a plurality of desiccants configured to move linearly between a dryer and a dehumidifier, the desiccants being configured to move together; and a motor configured to drive the desiccants.

18. The humidity adjusting apparatus according to claim 17, wherein the desiccants have a rectangular shape.

19. The humidity adjusting apparatus according to claim 17, further comprising: racks provided on each desiccant; and a pinion engaging the racks and connected to the motor.
