A tumble dryer has a drum for laundry, a drive motor for the drum, an air supply to the drum and an air discharge from the drum, a fan, including a fan drive, for generating an air stream to the drum through the air supply and away from the drum through the air discharge, and also heating means for heating the air stream. The temperature of and the moisture in the air which is discharged from the drum are detected. The profile of said temperature and moisture is compared with prespecification curves, which are stored in a memory, for the profile of said temperature and moisture by means of calculation means depending on the drying phase of the laundry. The operating point of the prespecification curve at which the drying program is located is determined in this way. The control arrangement influences the further drying program, on the basis of the operating point, by way of adjusting the temperature and/or the intensity of the air stream.

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.

A washing machine that can shorten the drying time by improving the drying efficiency of the washing machine. A washing machine includes a tub, a drum rotatably installed inside of the tub, a condensing duct formed on an inner wall of the tub, a heating duct provided outside the tub, a duct heater provided inside the heating duct, a fan configured to circulate air in the drum, the condensing duct, and the heating duct and a controller configured to rotate the drum at a first rotational speed so as to tumble laundry contained in the drum while controlling the duct heater to heat the air circulated by the fan. The controller may rotate the drum at a second rotational speed, which is higher than the first rotational speed to separate water from the laundry contained in the drum while controlling the duct heater to heat the circulating air.

A laundry treatment apparatus in accordance with the present disclosure includes a drum configured to accommodate laundry, an air channel through which air is flowed into or out of the drum, a fan configured to put pressure on air in the air channel for flowing of the air, a fan motor configured to rotate the fan and being controlled by adjusting of a RPM, an abnormal airflow detection unit disposed on the air channel and configured to detect whether an abnormal state of airflow is occurred, and a controller configured to cause the RPM of the fan motor to be increased. The controller configured to cause laundry to be dried by rotating the fan motor at a predetermined base RPM, and to cause the RPM to be increased if the abnormality of airflow is detected by the abnormal airflow detection unit while the fan motor is rotating.

A method for measuring the humidity of a laundry mass contained in a laundry treatment chamber of a laundry appliance. The method includes: providing a capacitor in the laundry appliance, the capacitor having, as part of the capacitor dielectric, the laundry mass; measuring a capacitance of the capacitor by means of an electronic circuitry electrically supplied by a supply voltage and a reference voltage. Providing a capacitor comprises: providing in the laundry appliance at least one conductive plate which forms a plate of the capacitor, and exploiting, as a second plate of the capacitor, routing lines distributing inside the laundry drying appliance the reference voltage.

The present invention relates to a laundry-care appliance (100) having a washing tub (107) and a deodorizing module (109) for dispensing deodorizing substance into the washing tub (107), wherein the deodorizing module (109) is connected to the washing tub (107) and comprises a radial fan (115) for ventilating the washing tub (107), wherein the radial fan (115) is drivable in a first direction of rotation (121) and in a second direction of rotation (123). The deodorizing module (109) is configured to dispense deodorizing substance into the washing tub (107) in a first period of time, wherein the radial fan (115) is drivable in the first direction of rotation (121) in the first period of time in order to distribute the deodorizing substance in the washing tub (107). The radial fen (115) is drivable in the second direction of rotation (123) in a second period of time following the first period of time, in order to remove the deodorizing substance from the washing tub (107) in the second period of time.
