Abstract:
1. A dehumidifying apparatus for a dryer, comprising 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, the heat exchanger including a water-cooled heat exchanger; a condenser case that covers the heat exchanger, wherein the heat exchanger is installed inside the condenser case such that condensate water flows along the heat exchanger and is directed to a lower portion of the condenser case; and an injection nozzle disposed upstream of the heat exchanger that injects water toward the heat exchanger, thereby removing foreign substances on the heat exchanger, wherein the injection nozzle is configured to spray the water so as to form a water curtain that extends in a direction traverse to a flow direction of the air into the water-cooled heat exchanger, wherein the injection nozzle is located within the condenser case and disposed above at least one duct that communicates with a surface of the condenser case, wherein the at least one duct that communicates with the condenser case is smaller than a surface of the condenser case, wherein the injection nozzle is diverged from a pipe that supplies the water to the heat exchanger, and wherein the water sprayed through the injection nozzle is introduced into die lower portion of the condenser case and discharged to an outside with the condensate water directed to the lower pardon of the condenser case.
