Abstract

A dehumidifier including an evaporator, a condenser, and a fan arranged in a main body. The fan includes a first blowing part to blow air having passed through both the evaporator and the condenser, and a second blowing part to selectively blow any one of air having passed through both the condenser and the evaporator and air having passed through only the evaporator. The dehumidifier may additionally function to supply cold air.

First claim

What is claimed is:

1. A dehumidifier comprising:
a main body;
an evaporator and a condenser arranged within the main body; and
a fan to suction air into the main body and discharge the air from the main body,
a first damper to selectively direct air that has moved through the evaporator and the condenser to the fan, or air that has moved through only the evaporator to the fan; and
wherein the fan includes a first blowing part and a second blowing part, and
wherein either the air having passed through both the evaporator and the condenser moves through the first and second blowing parts, or the air having passed through both the condenser and the evaporator moves through the first blowing part and the air having passed through only the evaporator moves through the second blowing part.

2. The dehumidifier according to claim 1 ,
wherein the first blowing part suctions air in one axial direction and discharges the air in an outward radial direction, and
wherein the second blowing part suctions air in an opposite axial direction and discharges the air in an outward radial direction.

3. The dehumidifier according to claim 1 , wherein the main body includes a suction aperture through which air is suctioned into the main body, a first discharge aperture through which air discharged from the first blowing part is discharged out of the main body, and a second discharge aperture through which air discharged from at least the second blowing part, among the first blowing part and the second blowing part, is discharged out of the main body.

4. The dehumidifier according to claim 3 , further comprising a second damper to guide air blown by the first blowing part so as to be selectively discharged through either the first discharge aperture or the second discharge aperture.

5. The dehumidifier according to claim 4 , wherein the main body includes a first discharge path to guide air to the first discharge aperture and a second discharge path to guide air to the second discharge aperture, and
wherein the first discharge path and the second discharge path meet.

6. The dehumidifier according to claim 5 , wherein the second damper is rotatably installed where the first discharge path and the second discharge path meet.

7. The dehumidifier according to claim 1 , wherein the main body includes a first suction path to guide air having passed through the evaporator to the condenser, a second suction path to guide air having passed through the condenser to the first blowing part, a third suction path branched from the first suction path to allow some of the air having passed through the evaporator to bypass the condenser, and a fourth suction path to guide air to be suctioned into the second blowing part,
wherein the second, third and fourth suction paths meet, and
wherein the first damper selectively connects either the second suction path or the third suction path to the fourth suction path.

8. The dehumidifier according to claim 7 , wherein the first damper is rotatably installed where the second suction path, the third suction path and the fourth suction path meet, and closes either the second suction path or the third suction path via rotation thereof.

9. The dehumidifier according to claim 1 , further comprising:
a motor to rotate the fan; and
a guide duct to receive the fan, the guide duct guiding air discharged from the fan,
wherein the guide duct includes a first duct in which the first blowing part is received, the first duct guiding air discharged from the first blowing part, and a second duct in which the second blowing part is received, the second duct guiding air discharged from the second blowing part.

10. The dehumidifier according to claim 1 , wherein the main body accommodates a drain pan, and a container in which water from the drain pan is stored.

11. A dehumidifier comprising:
a main body;
an evaporator and a condenser arranged within the main body; and
a fan to suction air into the main body and discharge the air from the main body,
wherein the fan includes a first blowing part to suction air in one axial direction and discharge the air in an outward radial direction, and a second blowing part to suction air in an opposite axial direction and discharge the air in an outward radial direction, and
wherein the main body includes a suction aperture through which air is suctioned into the main body, a first suction path to guide air, having been suctioned through the suction aperture and passed through the evaporator, to the condenser, a second suction path to guide air having passed through the condenser to the first blowing part, a third suction path branched from the first suction path to allow some of the air having passed through the evaporator to bypass the condenser, a fourth suction path selectively connected to any one of the second suction path and the third suction path to guide air such that any one of air having passed through both the evaporator and the condenser and air having passed through only the evaporator is selectively suctioned into the second blowing part, and a first damper to connect either the second suction path or the third suction path to the fourth suction path,
wherein the first damper is rotatably installed where the second suction path, the third suction path and the fourth suction path meet.

12. The dehumidifier according to claim 11 , wherein the main body includes a first discharge aperture through which air discharged from the first blowing part is discharged out of the main body, a second discharge aperture through which air discharged from at least the second blowing part among the first blowing part and the second blowing part is discharged out of the main body, a first discharge path to guide air to the first discharge aperture, a second discharge path to guide air to the second discharge aperture, and a second damper to allow air discharged from the first blowing part to be delivered to either the first discharge path or the second discharge path.

13. A dehumidifier comprising:
a main body;
an evaporator and a condenser arranged within the main body; and
a fan to force air into the main body and discharge the air from the main body;
a first damper to selectively direct air that has moved through the evaporator and the condenser to the fan, or air that has moved through only the evaporator to the fan,
wherein the fan includes a first blowing part and a second blowing part, and
wherein either the air having passed through both the evaporator and the condenser moves through the first and second blowing parts, or the air having passed through both the condenser and the evaporator moves through the first blowing part and the air having passed through only the evaporator moves through the second blowing part;
a suction aperture through which air is suctioned into the main body;
a first discharge aperture through which air discharged from the first blowing part is discharged out of the main body;
a second discharge aperture through which air discharged from at least the second blowing part among the first blowing part and the second blowing part, is discharged out of the main body,
wherein the second discharge aperture is installed at the main body to be oriented in a direction opposite to a direction in which the first discharge aperture is oriented; and
a second damper to guide air from the first blowing part to either the first discharge aperture or the second discharge aperture.

14. The dehumidifier according to claim 13 ,
wherein the first blowing part suctions air in one axial direction and discharges the air in an outward radial direction, and
wherein the second b
