Abstract:
A control method of a laundry treatment apparatus is disclosed which includes a course setting procedure receiving a control command including RPM control data of an impeller, RPM control data of a compressor or opening degree control data of an expansion valve, a hot air supply procedure for supplying heated air to a drum through control of the impeller, compressor and expansion valve, a temperature measurement procedure measuring temperature of air introduced into the drum during execution of the hot air supply procedure, a first control procedure for controlling the impeller, compressor and expansion valve based on the control command when the measured temperature is equal to or higher than a reference temperature, and a second control procedure controlling the impeller, compressor and expansion valve based on a control command different from the control command set in the course setting procedure when the measured temperature is lower than the reference temperature.

Claim (Index 1):
A control method of a laundry treatment apparatus that includes a drum, a duct at an outside of the drum and configured to guide air exhausted from the drum, an impeller disposed in the duct and configured to circulate air, a refrigerant tube configured to form a circulation path of refrigerant, an evaporator disposed in the duct and configured to allow heat exchange between the refrigerant and air introduced into the duct so as to evaporate the refrigerant, a condenser disposed in the duct and configured to allow heat exchange between the refrigerant and air passing around the evaporator so as to condense the refrigerant, a compressor configured to compress the refrigerant from the evaporator and to supply the compressed refrigerant to the condenser, an expansion valve configured to adjust a pressure of the refrigerant transferred from the condenser to the evaporator based on control of an opening degree of the refrigerant tube, and a temperature sensor configured to sense a temperature of the air from the drum, comprising:\n a course setting procedure for receiving a control command that includes at least one of data for control of RPM of the impeller, data for control of RPM of the compressor, and data for control of opening degree of the expansion valve; a hot air supply procedure including an operation for supplying heated air to the drum based on control of the impeller, the compressor and the expansion valve; a temperature measurement procedure for sensing, by the temperature sensor, a temperature of the air in the duct during the hot air supply procedure; a first control procedure for controlling the impeller, the compressor and the expansion valve based on the control command when the temperature sensed by the temperature sensor is equal to or higher than a predetermined reference temperature; and a second control procedure for controlling the impeller, the compressor and the expansion valve based on a control command different from the control command in the course setting procedure when the temperature sensed by the temperature sensor is less than the predetermined reference temperature.
