Abstract: The present invention relates to a hot air generating apparatus and a dryer having the same. The hot air generating apparatus comprises a temperature sensing unit, and a gas supply unit controlling a flowing amount of gas to be supplied according to a temperature of hot air sensed by the temperature sensing unit, wherein when the temperature of the hot air sensed by the temperature sensing unit approaches a pre-set threshold value, the flowing amount of gas to be supplied is gradually reduced, thereby being capable of continuously supplying hot air without being frequently turned on/off.

Abstract: Disclosed is the dehumidifying apparatus for a dryer comprising: a case; a drum disposed inside the case and for receiving objects to be dried therein; and a hot air supplying unit for supplying hot air into the drum and drying the objects to be dried, the dehumidifying apparatus, comprising: a plurality of dehumidifying units, thereby capable of controlling humidity of exhausted air to a required level of humidity by removing moisture contained in air exhausted from the plurality of dehumidifying units in multiple steps.

Abstract: Disclosed is the dehumidifying apparatus for a dryer comprising: a case; a drum disposed inside the case and for receiving objects to be dried therein; and a hot air supplying unit for supplying hot air into the drum and drying the objects to be dried, the dehumidifying apparatus, comprising: a heat exchanger for heat exchange with air flowing from the drum; and an injection nozzle portion disposed between the hot air supplying unit and the heat exchanger so as to inject a certain jet. According to the dehumidifying apparatus for a dryer, when gas introduced into the dehumidifying apparatus from the drum through a jet passes through the jet, foreign substances such as lint, etc. contained in the gas may be separated, thereby preventing accumulation of the foreign substances on the dehumidifying apparatus.

Abstract: A ductless dryer is disclosed. The ductless dryer according to the present invention includes a hot air supply unit providing hot air into a drum and controlling heat for heating the air according to air volume, and a heat exchange unit dehumidifying humid air exhausted from the drum and controlling the amount of water used for dehumidifying according to a dew point temperature of the humid air.

Abstract: Disclosed is a ductless dryer having a heat exchanger module in accordance with the present invention. The heat exchanger module is configured to have a water-supplying inlet disposed at an outlet for air and to be provided with a sealing unit, a drain recess and a leakage preventing protrusion. Thus, a dehumidifying performance for humid air is enhanced. Accordingly, it is capable of preventing mold from being gathered on a wall of an installation space caused by exhausting the air in which moisture is not removed. Also, it is capable of preventing a user in the installation space from feeling unpleasant caused by exhausting the air in which the moisture is not removed to the installation space.

Abstract: A ductless dryer includes a sealing unit for preventing a leakage of lint through a gap of a filter installation portion. The sealing unit includes a sealing protrusion formed at the filter, a sealing recess disposed at a filter installation duct of the circulation duct for inserting the sealing protrusion thereinto, and a sealing member inserted into the sealing recess and contacting the sealing protrusion. Accordingly, the ductless dryer according to the present invention can prevent the leakage of lint through a gap of a filter installation portion and the malfunction of the ductless dryer by leaked lint, thereby enhancing reliability of the dryer.

Abstract: A ductless type clothes drier comprises: a heat pump system including a condenser configured to supply hot air into the drum, and an evaporator configured to remove moisture inside air exhausted from the drum; and a lint removing unit configured to inject water to the evaporator so that lint on the evaporator can be removed. Accordingly, without using water, moisture included in exhausted air can be removed as a heat exchange process is performed at the evaporator. Water for removing moisture included in air does not have to be supplied to the ductless type clothes drier, thereby solving cost increase due to increase of a water consumption amount. Furthermore, since clean water remained after being used for heat exchange is not discarded, waste of water resources is prevented. Also, the conventional problem that the ductless type clothes drier has a difficulty in being commercialized due to increase of a water consumption amount is solved.

Abstract: A ductless type clothes drier comprises a dew condensation preventing cover configured to remove moisture included in finally exhausted air discharged to a wall surface behind a body via the heat exchanger. Accordingly, finally exhausted air including moisture is prevented from directly contacting a wall surface, thereby preventing dew condensation phenomenon occurring as moisture included therein is condensed on the wall surface. As a result, can be solved the conventional problem that stains or fungi are reproduced on the wall surface thus to cause appearance degradation and sanitary problems.

Abstract: A clothes drier comprises a dehumidifying unit configured to dehumidify air exhausted from the drum, and to control an amount of water to be supplied thereto according to a drying level of clothes. As an amount of water supplied to the dehumidifying unit is controlled according to a drying level of clothes, a water consumption amount is reduced.

Abstract: A clothes drier comprises: a body; a drum rotatably installed at the body; a hot air supply unit configured to supply hot air into the drum; a heat exchanger configured to dehumidify air exhausted from the drum; a pipe unit configured to supply water to the heat exchanger and collect water from the heat exchanger; and a freeze damage preventing unit installed on the pipe unit. The clothes drier is provided with the freeze damage preventing unit configured to partially or completely discharge out water remaining in the heat exchanger after the clothes drier is stopped.
