  • Patent number: 7526879
    Abstract: A drum washing machine and a clothes dryer equipped with a thermoelectric module are disclosed. The thermoelectric module includes a heat absorption side and a heat dissipation side which absorbs and dissipates heat at a junction between two dissimilar metals depending on direction of current flow through the junction. The heat absorption side is disposed at a hot air flowing passage. Accordingly, the drying apparatus can increase energy efficiency with minor structural modification and becomes environmentally friendly unlike a conventional drying apparatus using a heat pump.

  • Publication number: 20090071033
    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.

  • Publication number: 20090056161
    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.

  • Publication number: 20090038178
    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.

  • Publication number: 20090038173
    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. Accordingly, freeze damage of the heat exchanger during winter time is prevented.

  • Publication number: 20090025250
    Abstract: A method for controlling an automatic dryer is disclosed, which can determine a dryness level based on information relating the laundry by an initial average value of a sensing means, to thereby achieve stability and reliability in a drying process, the method comprising sensing whether the amount of laundry is small or large by using an average output value in a preset time period of an initial drying stage; detecting a saturation voltage generating point of the sensor; and performing a drying cycle based on each dryness level by using information for the amount of laundry and the saturation voltage generating point.

  • Publication number: 20080313923
    Abstract: A clogging degree deciding method for a dryer, which can accurately determine a clogging degree of an air passage, even when there is an influence of external environments, is disclosed. The clogging degree deciding method includes reading information as to clogging of an air passage, and displaying a clogging degree of an exhaust duct or a clogging degree of a filter in accordance with the read clogging information. The clogging information includes an ON/OFF duty ratio of a temperature control member. The displaying step includes comparing a difference between two ON/Off duty ratios finally stored with a filter-clogging determination reference value, and determining the clogging degree of the filter, based on a result of the comparison. Accordingly, it is possible to provide the clogging degrees of the exhaust duct and filter to the user.

  • Publication number: 20080282568
    Abstract: A dryer, which can control the amount of heat generated from a heater in accordance with the clogging degree of an air passage, is disclosed. The dryer includes a heater for heating air passing through an air passage, the heater generating heat in a controlled amount, and a controller for controlling the amount of heat generated from the heater in accordance with a clogging degree of the air passage. Since the amount of generate heat is controlled in accordance with the clogging degree of the air passage, it is possible to achieve an enhancement in power consumption efficiency.
