A laundry treatment apparatus includes a washing machine module and a drying machine module that are integrally installed in a common cabinet, and a single drying module configured to produce dry hot air. The laundry treatment apparatus has a reduced product size and performs a method for drying laundry in a washing drum and a drying drum. The method includes detecting a dryness in real time while performing drying processes simultaneously in the washing drum and the drying drum by the common drying module, and controlling an amount of supplied dry hot air and an amount of recovered dry hot air to be different to reduce an overall drying process time and electric power consumption. The drying processes performed in the drying machine of the washing machine are simultaneously completed to improve convenience for a user.

A laundry treatment appliance includes a cabinet; a basket rotatably mounted within the cabinet and defining a chamber configured for receiving a load of clothes; a door rotatably mounted to the cabinet; a sensor positioned within the cabinet, the sensor configured to measure a humidity of air within the cabinet; and a controller operably coupled to the sensor, the controller being configured to determine that an operating cycle of the laundry treatment appliance has been completed; determine that a user has removed the load of clothes; obtain one or more humidity measurements of the chamber using the sensor after determining that the user has removed the load of clothes; identify a leftover article remaining in the chamber by analyzing the one or more humidity measurements of the chamber; and implement a responsive action in response to identifying the leftover article remaining in the chamber.

A method of operating a laundry treatment appliance including a chamber for receiving a laundry load and a water supply provided within the chamber includes determining a target moisture level of the laundry load; initiating a drying cycle of the laundry load, the drying cycle including a primary drying time; initiating a spray operation for providing moisture into the chamber; determining that a measured moisture level of the laundry load meets a moisture goal based on the target moisture level; and ceasing the spray operation in response to determining that the measured moisture level meets the moisture goal.

A duty cycle heating portion of a drying cycle is initiated, in which a heating element of the clothes dryer is cycled on and off. An average baseline value is established for one or more of peak exhaust temperature of exhaust temperature of the clothes dryer or peak evaporation rate of evaporation rate of the clothes dryer. The duty cycle heating portion is continued until a peak delta between current exhaust temperature or the evaporation rate and the average baseline value exceeds a predefined threshold difference. The dryer transitions from the duty cycle heating portion to a continuous heating portion of the drying cycle, in which the heating element of the clothes dryer is continuously powered. The heating element is disengaged responsive to one or more criteria indicating completion of the drying cycle.

A heat pump appliance may include a cabinet, a sealed thermodynamic assembly, a blower fan, a temperature sensor, and a controller. The sealed thermodynamic assembly may include a fluid compressor, an evaporator, and a condenser disposed along the air path. The temperature sensor may be mounted to the evaporator to detect temperature at the evaporator. The controller may be configured to direct a drying operation. The drying operation may include activating the fluid compressor to motivate a refrigerant through the sealed thermodynamic assembly, activating the blower fan to motivate the airflow across the condenser, directing the fluid compressor to an inactive state following activating the blower fan, detecting an evaporator temperature at the temperature sensor while the fluid compressor is in the inactive state following activating the blower fan, and adjusting activation of the blower fan based on the detected evaporator temperature.
