A control method for a laundry treating apparatus includes supplying water to a tub by controlling a water supply unit of a washing machine, supplying the heated air to a drying drum through a heat exchanger of a dryer, transmitting a control signal requesting reduction of a current amount per hour supplied to the heat exchanger to the dryer by the washing machine, lowering the current amount if a temperature of the air discharged from the drying drum or a temperature of a refrigerant heat-exchanged with the air by the heat exchanger is higher than a preset first reference temperature, heating the water stored in the tub by operating the heating unit after starting to lower the current amount, and separating particles from laundry by rotating a washing drum provided inside the tub.

A laundry treating apparatus includes first and second treating apparatuses; a first display on which a control command that may be input to the first treating apparatus; a first apparatus input unit for inputting the control command to the first treating apparatus; a first display controller controlling the first display and the first apparatus input unit; a first apparatus first power circuit connecting the first display controller and the first apparatus input unit to a power source; a first apparatus second power circuit connecting the power source with the first load controller, switched by a first controller switch; and a first apparatus third power circuit connecting the power source with the first driving unit, switched by a first load portion switch. When the control command is input through the first apparatus input unit, the first display controller controls the first controller switch to close the first apparatus second power circuit.

A method of drying laundry in a laundry treating appliance having a treating chamber in which the laundry is received for drying comprises moving the treating chamber to redistribute the laundry, supplying air to the treating chamber to define a supply air flow, exhausting the supplied air from the treating chamber to define an exhaust air flow, actuating a heater at full output to heat the air supplied to the treating chamber, turning the heater off, and maintaining a maximum evaporation rate for a duration of time by operating the heater.

A method for controlling a laundry drying machine having a laundry treating chamber and a control unit which receives a signal indicative of laundry moisture from a moisture sensor. The method includes receiving a user input of a laundry treating program, and, in the machine initialization phase, comparing the laundry moisture indicated by the signal to a first threshold, which is stored in the control unit and is indicative of dried laundry or empty threating chamber. If the signal is determined to be equal or less than the first threshold, one or more of the following actions is performed: carrying out only a portion of the selected laundry treating program; skipping the program main phase; starting the program final phase; stopping the laundry treating program; providing a notification of dried laundry and/or empty treating chamber.

A heater arrangement for a multi-compartment appliance comprises a first heater, a second heater, and a relay. The first heater is disposed within a first airflow path for a first dryer compartment. The second heater is disposed within a second airflow path for a second dryer compartment. The relay interconnects, via an electrical harness, the first and second heaters. The relay, responsive to a demand for heat to the first dryer compartment and the first heater having a temperature being less than a target temperature, diverts power to the first heater.

A dryer appliance and a method of operating the same are provided. In one aspect, the dryer appliance includes a drum rotatably mounted within a cabinet. The drum defines a chamber that is in fluid communication with a conditioning system of the dryer appliance. The conditioning system heats air circulating therethrough and removes water from the process air. A collection tank collects the water and a drain pump removes water from the collection tank intermittently when the water reaches a predetermined level. The frequency at which the drain pump removes water from the collection tank is utilized to determine the moisture extraction rate indicative of the rate at which moisture is removed from the clothes. The moisture extraction rate is utilized to control the mass flow rate of refrigerant in a heat pump sealed system or the process air flow rate through the closed loop air circuit.

The present disclosure relates to a laundry treatment machine. The laundry treatment machine according to an embodiment of the present invention includes a casing; a door attached to the casing; a washing tub disposed inside the casing; a heating unit; a blower for supplying to the washing tub; a temperature detector for detecting a temperature of the washing tub; a motor for rotating the washing tub; a driving unit for driving the motor; and a controller to control the blower to operate in a first drying mode, and to control the heating unit to intermittently output a first power during a first period after the operation of the blower while controlling an operating time of the heating unit to increase during the first period. Accordingly, the power consumption can be reduced while reducing the drying period in the drying mode.

A controlling method for a dryer is provided. The controlling method includes the steps of rotating a drum in a first direction and a second direction which is an opposite direction to the first direction by a motor, measuring the load of the motor and identifying the weight of drying materials based on the lower motor load among the load of the motor measured during rotation in the first direction and the load of the motor measured during rotation in the second direction.

A heater arrangement for a multi-compartment appliance comprises a first heater, a second heater, and a relay. The first heater is disposed within a first airflow path for a first dryer compartment. The second heater is disposed within a second airflow path for a second dryer compartment. The relay interconnects, via an electrical harness, the first and second heaters. The relay, responsive to a demand for heat to the first dryer compartment and the first heater having a temperature being less than a target temperature, diverts power to the first heater.

A clothes dryer is disclosed. The clothes dryer includes a rotatably disposed drum, a heat pump system including a compressor configured to compress a refrigerant and a condenser configured to condense the refrigerant, a heater configured to heat air supplied to the interior of the drum, a first temperature sensor configured to detect a temperature of air passing through the interior of the drum, a second temperature sensor configured to detect a temperature of the compressor, and a processor configured to control an operation of the compressor on the basis of the temperature of the air passing through the interior of the drum detected by the first temperature sensor and control an operation of the heater on the basis of the temperature of the compressor detected by the second temperature sensor.
