Disclosed are an object treating apparatus, and more particularly, an object treating apparatus for heating a drum using an induction heater and a control method thereof. The object treating apparatus includes a tub; a drum rotatably disposed within the tub and accommodating an object therein; an induction heater disposed on the tub and configured to heat an outer circumferential face of the drum contacting the heater; a motor to rotate the drum; and a processor configured to control an operation of the induction heater to dry the object, wherein the processor is configured to: control revolution per minute (RPM) of the drum to perform at least two drum motions having at least two different target RPMs respectively when drying the object.

Disclosed herein is a drain pump driving apparatus and a laundry treatment machine including the same. The drain pump driving apparatus and the laundry treatment machine including the same according to an embodiment of the present invention include a motor to operate the drain pump, an inverter to convert a direct current (DC) power to an alternating current (AC) power by a switching operation and output the converted AC power to the motor, an output current detector to detect an output current flowing to the motor, and a controller to control the inverter, wherein the controller may calculate a speed ripple of the motor based on the output current and performs a control operation based on the calculated speed ripple of the motor to change a speed of the motor.

A washing machine includes a first washing compartment to hold a first set of articles to be washed and a second washing compartment to holds a second set of articles to be washed, the second washing compartment having an inserted position and a removed position. A liquid flow valve is configured to connect to an external liquid source to selectively control flow of liquid from the external liquid source and into one or more of the first washing compartment and the second washing compartment. An electric motor is configured to rotate the first washing compartment, and the second washing compartment, when the second washing compartment is in the inserted position. A controller, in communication with the electric motor, determines a mass of the second set of articles and then determines, as a function of the determined mass, a volume of water to be added to the second washing compartment.

A method of operating a laundry treating appliance with a treating chamber for treating a load of laundry the method comprising supplying a rinse to the treating chamber during a rinse cycle, rotating the treating chamber at a tumbling speed, spinning the treating chamber in an extraction cycle to remove excess moisture from the load of laundry, sensing a parameter indicative of a remaining moisture content value in the load of laundry, comparing the remaining moisture content value to a pre-determined remaining moisture content value.

A laundry dryer includes a cabinet, a user interface that is operably coupled to the cabinet, a motor that is disposed within the cabinet and communicatively coupled with the user interface, and a controller that is communicatively coupled with the user interface and the motor, respectively. The controller includes a memory storage that includes a plurality of night routines. The controller is configured with a selectable time point and is further configured to select at least one of the plurality of night routines at the selectable time point.

Disclosed are an object treating apparatus, and more particularly, an object treating apparatus for heating a drum using an induction heater and a control method thereof. The object treating apparatus includes a tub; a drum rotatably disposed within the tub and accommodating an object therein; an induction heater disposed on the tub and configured to heat an outer circumferential face of the drum contacting the heater; a motor to rotate the drum; and a processor configured to control an operation of the induction heater to dry the object, wherein the processor is configured to control revolution per minute (RPM) of the drum to perform, during drying: a conductive accelerating motion having a target RPM in which the object rotates integrally with the drum while the object is in close contact with an inner circumferential face of the drum; and a rearrangement motion having a target RPM lower than the target RPM of the conductive accelerating motion.

A method of controlling a washing machine includes spraying water into a drum through a direct water nozzle, rotating the drum at a spin-dry rinse speed, draining water from a tub while rotating the drum at the spin-dry rinse speed, supplying water to the tub to increase a water level in the tub, circulating water in the tub to spray circulated water into the drum through a circulation nozzle, rotating the drum at a laundry adherence speed lower than the spin-dry rinse speed, and in a state in which draining water from the tub and spraying the circulated water are stopped and at least a portion of the drum is disposed below the water level in the tub, accelerating the drum from the laundry adherence speed to a first tub cleaning speed.

A method and system for setting parameters of a treatment cycle in a household appliance is provided. First a model establishing a relationship between sets of configuration parameter values of achievable treatment performance is obtained. Then a target treatment performance for the treatment cycle is obtained. Values for a subset of a configuration parameter are fixed, the subset comprising at most all configuration parameters but a remaining configuration parameter. Then, a value for the remaining configuration parameter is determined. For this value, a difference between the target treatment performance and an achievable treatment performance predicted by the model using said value is below a predetermined threshold. Finally, the parameters of the treatment cycle, which can be setting parameters of the treatment cycle in the household appliance are output. The parameters comprise the determined value and the fixed values.
