A laundry treating apparatus includes a drum for receiving laundry; a motor for driving the drum; a drying unit for drying the laundry by heating the drum; and a memory for storing a control temperature table in which a control temperature according to the lapse of drying time of the laundry is recorded, wherein the drying unit operates on the basis of a control temperature table obtained by shifting the stored control temperature table at least one time.

A method of operating a dryer appliance includes determining a remaining moisture content of a load of articles to be dried in the dryer appliance and estimating an energy requirement for drying the load of articles based on the determined remaining moisture content of the load of articles. The method also includes activating a heating system of the dryer appliance during a dry cycle of the dryer appliance while tracking an energy output of the heating system during the dry cycle. The method further includes comparing the tracked energy output to the estimated energy requirement. When the tracked energy output is greater than a predetermined threshold percentage of the estimated energy requirement, a user notification is provided.

A method of operating a laundry treating appliance for treating laundry according to a treating cycle of operation. The laundry treating appliance comprises a treating chamber for receiving the laundry that is selectively accessible through a door movable between opened and closed positions. The method comprises determining at the end of a laundry treating cycle whether the door has been opened and subsequently reclosed and reducing humidity in the treating chamber after the determination that the door has been reclosed.

A clothes treating apparatus is provided. The clothes treating apparatus includes a drying device including a heat exchanger, a compressor, a fan, and a drain hole formed to drain condensate water produced by the heat exchanger, a tub arranged underneath the drying device and storing the condensate water drained through the drain hole, a drain pump configured to drain the condensate water stored in the tub, a water level sensor configured to detect a water level in the tub, a drum rotationally arranged in the tub, a temperature sensor configured to detect temperature of air discharged from the drum, memory storing instructions, and one or more processors communicatively coupled to the drying device, the drain pump, the water level sensor, the temperature sensor, and the memory, wherein the instructions, when executed by the one or more processors individually or collectively, cause the clothes treating apparatus to operate the drying device, based on a start of a drying process, operate the drain pump, based on the water level in the tub reaching a preset water level while the drying process is in progress, and determine a dryness level of an object accommodated in the drum according to temperature of air discharged out of the drum, based on a number of operations of the drain pump being equal to or greater than a predetermined number of times during a preset period of time after the start of the drying process.

A washing machine according to an aspect of the disclosure includes: a drum; a tub accommodating the drum and storing water; a drum motor configured to provide a rotation force to the drum; a water supplier configured to supply water to the tub; a hot air supplier configured to supply hot air to the drum; a current sensor configured to output a current signal corresponding to a magnitude of current applied to the drum motor; and a controller configured to perform a washing operation while controlling the water supplier and the drum motor, and perform a drying operation while controlling the hot air supplier and the drum motor.

A method of operating a laundry treatment appliance includes initiating a drying cycle, the drying cycle including a first goal value of a moisture goal of a laundry load; initiating a sensing process, the sensing process including measuring, via the moisture sensor, a first moisture level within a first predetermined time interval; determining that the first moisture level is above the first goal value within the first predetermined time interval; measuring, as part of the sensing process via the moisture sensor, a second moisture level within a second predetermined time interval subsequent to the first predetermined time interval; determining the second moisture level is greater than the first moisture level; and setting the moisture goal based on determining that the second moisture level is greater than the first moisture level.

A dryness sensing device configured to sense a dryness of a laundry according to an embodiment of present disclosure may comprise a case having a length and a thickness; a first sensor disposed on a first side of the case and configured to measure a resistance to sense a surface dryness of the laundry; and a second sensor is disposed on a second side of the case facing the first side and configured to measure a capacitance to sense an internal dryness of the laundry, wherein the first sensor and an electrode plate provided in the second sensor are arranged so as not to overlap each other in a thickness direction of the case.

A method for controlling a laundry treating apparatus includes an air supplying step of supplying heated air to the drum through the heat exchange part and a first motion executing step executed while the air supplying step is in progress. The first motion executing step alternately executes a first acceleration mode of rotating the drum at an rpm inducing a centrifugal force equal to or greater than 1G along one of a clockwise direction and a counterclockwise direction and a first deceleration mode of rotating the drum at an rpm inducing a centrifugal force smaller than 1G in a direction equal to a rotational direction set for the first acceleration mode.

The present disclosure provides a drying device and a method for controlling same. The drying device of the present disclosure may comprise: a drum; a driving unit; a heater to heat air supplied to the interior of the drum; a communication interface; and a processor that: when a user command for a drying cycle is received, controls the driving unit so as to rotate the drum in a preset pattern; when data generated on a basis of motion of a sensing device is received through the communication interface from at least one sensing device, identifies a sensing device that has a motion corresponding to the preset pattern among the at least one sensing device; and controls the driving unit and the heater so as to perform a drying cycle on the basis of humidity data received through the communication interface from the identified sensing device.
