A laundry treating apparatus may comprise a cabinet that defines an exterior design; a drum rotatably mounted in the cabinet and configured to accommodate laundry; a drive unit or motor configured to rotate the drum; a hot air supply unit or hot air blower configured to supply high-temperature air to the drum and in communication with the drum; a collection portion or liquid chamber provided to collect water condensed from the drum and in communication with the hot air supply unit; and a drainage pump configured to discharge the water collected in the collection portion outside the cabinet such that the laundry treating apparatus may sense whether the condensate collected in the collection portion is frozen and thaw the frozen condensate. A control method of the laundry treating apparatus may be provided to thaw and operate the laundry treating apparatus.

The present disclosure relates to an integrated washing-drying machine and a method of controlling the same, the integrated washing-drying machine including a housing, a drying drum disposed at an upper side in the housing and configured to accommodate and dry laundry, a washing drum disposed at a lower side in the housing and configured to accommodate and wash laundry, a heat pump having an evaporator, a compressor, and a condenser and produce hot air for drying laundry and supply the hot air to the drying drum, and a cleaning means configured to clean the condenser by spraying cleaning water to the condenser. In this case, the cleaning means uses, as the cleaning water, at least any one of condensate water produced in the evaporator and washing water to be supplied to the washing drum. With this configuration, when the amount of condensate water is insufficient, the washing water is additionally supplied to clean the condenser cleanly.

Disclosed is a laundry treating apparatus including: a cabinet having a laundry inlet and a filter insertion hole defined in a front face thereof; a drum rotatably disposed inside the cabinet and having a laundry storage space defined therein communicating with the laundry inlet; a duct disposed inside the cabinet, wherein the duct defines a channel for supplying air discharged from the drum back to the drum; a fan to move air along the duct; a heat exchanger including a heat-absorber to remove moisture from air introduced into the duct and a heat-emitter disposed inside the duct to heat air passing through the heat-absorber; a water collector constructed to communicate with the duct and to store therein water discharged from the water passing through the heat-absorber; a filter assembly including: a filter assembly body attachable to or detachable from the duct and constructed to be extended from or retractable into the cabinet through the filter insertion hole; a first filter disposed in the filter assembly body to filter fluid moving to the heat-absorber; and a second filter disposed in the filter assembly body to filter fluid moving to the water collector, wherein the second filter is positioned below the first filter; a water discharger detachably disposed in the cabinet and having a water storage space defined therein; a water discharger supply pipe for supplying water stored in the water collector to the water discharger; a water ejector configured to eject water into the first filter; and a water ejector supply pipe for supplying water stored in the water collector to the water ejector. Further, a method for controlling the apparatus is disclosed.

Disclosed is a laundry treating apparatus including: a water discharger supply pipe for supplying water stored in a water collector to a water discharger; a water supply pipe constructed to connect the water discharger and the water collector to each other; and a water collector water-level sensor for measuring a water-level inside the water collector, and a controller configured to control the laundry treating apparatus comprising: a water-level sensing operation in which the water collector water-level sensor measures the water-level of the water collector during a drying operation; and a cleaning water supply operation in which when the water-level of the water collector is lower than a predefined cleaning-related reference water-level, a water supply valve is controlled to supply water stored in the water discharger to the water collector.

The present disclosure relates to a laundry dryer control method comprising: a sterilizing and drying step of increasing the internal temperature of a cabinet for sterilization; a steam-washing step of supplying steam into a drum, in order to sterilize the drum, after the sterilizing and drying step; and a blowing step of circulating the air inside the drum after the steam-washing step, and thus the temperature of the drum is controlled so as to be greater than or equal to a reference temperature at which sterilization is performed so that the drum is sterilized.

A fluid flow system for a laundry appliance includes a blower that delivers process air along an airflow path having a heat exchanger. A drain channel receives condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel and on to a sump for collecting fluid, including the condensate. A pump seat and a fluid outlet are integrally formed in a sump cover. A pump directs the fluid from the sump to the fluid outlet. A fluid level sensor detects at least minimum and maximum capacities of the fluid in the sump. When the fluid is below the minimum capacity, the pump defines an idle state. When the fluid reaches the minimum capacity, the pump defines an active state. When the fluid exceeds the maximum capacity, the pump directs the fluid to the fluid outlet.

A laundry appliance includes a rotating drum for processing laundry. A blower directs process air through an airflow path that includes the rotating drum. A heat exchanger is positioned within the airflow path that dehumidifies the process air. A fixedly-secured lint filter captures lint from the process air at a position upstream of the heat exchanger. A fluid spray system has spray nozzles that deliver fluid to a surface of the fixedly-secured lint filter. Each spray nozzle of the plurality of spray nozzles directs captured lint away from the fixedly-secured lint filter.

A clothes treating apparatus is provided that may include an accommodation chamber, in which an object may be accommodated; a first heat pump cycle having a first evaporator, a first compressor, a first condenser, and a first expansion valve; a second heat pump cycle having a second evaporator, a second compressor, a second condenser, and a second expansion valve, and arranged such that air introduced into the accommodation chamber passes through the first evaporator, the second evaporator, the second condenser and the first condenser, sequentially; and a controller configured to control an operation of the first and second heat pump cycles. At least one of the first compressor or the second compressor may be provided with an inverter that changes a drive speed of the compressor through a frequency conversion. The controller may drive the at least one of the first compressor or the second compressor within a predetermined drive range, by controlling the drive speed of the at least one of the first compressor or the second compressor using the inverter.

Disclosed is a clothes treatment apparatus, comprising a clothes drying device, a first drainage pipe, a second drainage pipe, a drainage pump and a controller, wherein the clothes drying device is provided with a water accumulation tank; an inlet of the first drainage pipe is in communication with the water accumulation tank; a water outlet of the drainage pump is in communication with the second drainage pipe; and a water inlet of the drainage pump is in communication with the water accumulation tank. By means of the additional provision of the drainage pump and the second drainage pipe, the clothes treatment apparatus can discharge water in the water accumulation tank in a timely manner, and the drainage performance of the clothes drying device is improved.
