A dehumidifying apparatus for a dryer is provided that includes a case, a drum disposed inside the case that receives objects to be dried therein, and a hot air supplier that supplies hot air into the drum and dries the objects to be dried. The dehumidifying apparatus includes a heat exchanger that heat exchanges with air flowing from the drum, and an injection nozzle portion disposed between the hot air supplier and the heat exchanger so as to inject a certain jet. When gas introduced into the dehumidifying apparatus from the drum passes through the jet, foreign substances such as lint, contained in the gas may be separated, thereby preventing accumulation of the foreign substances on the dehumidifying apparatus.

1. A dehumidifying apparatus for a dryer, the dryer including a case; a drum disposed inside the case that receives objects to be dried therein; and a hot air supplier that supplies hot air into the drum and dries the objects to be dried, the dehumidifying apparatus comprising: a heat exchanger that cools air flowing from the drum;an injection nozzle disposed upstream of the heat exchanger that injects a predetermined material toward the heat exchanger, thereby removing foreign substances on the heat exchanger, wherein the injection nozzle is configured to be movable, and wherein the injection nozzle is disposed above the heat exchanger;a drive motor; anda flexible pipe capable of being flexibly deformed, disposed between the injection nozzle and a pipe that supplies the predetermined material to the injection nozzle, wherein the flexible pipe allows the injection nozzle to move via the drive motor in a state in which the pipe that supplies the predetermined material to the injection nozzle is fixed, and wherein a first end of the injection nozzle is connected to the flexible pipe and a second end of the injection nozzle is connected to the drive motor. 2. The dehumidifying apparatus of claim 1, wherein the injection nozzle is configured to be movable so as to adjust an injection direction of the predetermined material. 3. The dehumidifying apparatus of claim 2, wherein the drive motor is configured to drive the injection nozzle to rotate, and wherein a controller controls the drive motor so that the injection nozzle is rotatable within a predetermined angle. 4. The dehumidifying apparatus of claim 3, wherein the controller controls the drive motor to operate for a predetermined period of time. 5. The dehumidifying apparatus of claim 1, wherein the injection nozzle is configured to be movable so as to adjust an injection range of the predetermined material. 6. The dehumidifying apparatus of claim 5, wherein the drive motor is configured to generate a drive force, wherein a plurality of gears transfers the drive force of the drive motor to the injection nozzle, and wherein a controller controls the drive motor so that the injection nozzle moves within the predetermined range. 7. The dehumidifying apparatus of claim 6, wherein the controller controls the drive motor to operate for a predetermined period of time. 8. The dehumidifying apparatus of claim 1, wherein the injection nozzle injects at least a portion of the predetermined material into the air introduced into the heat exchanger. 9. The dehumidifying apparatus of claim 1, wherein the injection nozzle injects at least a portion of the predetermined material toward the heat exchanger. 10. The dehumidifying apparatus of claim 1, wherein the injection nozzle injects the predetermined material downwardly. 11. The dehumidifying apparatus of claim 1, wherein the injection nozzle includes a plurality of injection holes that injects the predetermined material. 12. The dehumidifying apparatus of claim 1, wherein the predetermined material injected from the injection nozzle is contained in a water tank that receives condensate water discharged by being condensed from the air. 13. The dehumidifying apparatus of claim 1, wherein the predetermined material injected from the injection nozzle is of a relatively low temperature compared to the air introduced into the heat exchanger. 14. The dehumidifying apparatus of claim 1, wherein the predetermined material injected from the injection nozzle comprises water. 15. The dehumidifying apparatus of claim 1, wherein the predetermined material injected from the injection nozzle comprises air. 16. The dehumidifying apparatus of claim 15, further including: a compressor that compresses the air. 17. A dryer including the dehumidifying apparatus of claim 1, a case, a drum disposed inside the case that receives objects to be dried therein, and a hot air supplier that supplies hot air into the drum and dries the objects to be dried.
