A laundry treatment assembly includes a washing machine appliance including a user interface and a dryer appliance, the dryer appliance including a dryer wireless communication module and a dryer controller operably coupled to the dryer wireless communication module, the dryer controller being configured to perform an operation including generating a plurality of request identification codes; emitting a first request identification code; emitting, after an expiration of a predetermined refresh period, a second request identification code; receiving a data package from the washing machine appliance, the data package including a start command to initiate a drying cycle of the dryer appliance and a discrete code of the plurality of request identification codes; and implementing a responsive action in response to receiving the data package.

A drying time prediction method includes: obtaining an operation condition set at the start of operation of a first dryer; obtaining the first actual operation time period of each of at least one first operation performed by the first dryer; obtaining operation finish time information from a learned model by inputting, to the learned model, the operation condition and first actual information that is based on the first actual operation time period, the operation finish time information being related to the finish time of the operation started under the operation condition; and outputting first information based on the operation finish time information.

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.

A laundry dryer control method includes a sterilizing drying step of increasing the internal temperature of a cabinet for sterilization, a steam-washing step of supplying steam into a drum to sterilize the drum after the sterilizing drying step, and a blowing step of circulating air inside the drum after the steam-washing step. The temperature of the drum is controlled to be greater than or equal to a reference temperature for sterilization.

A combination washer/dryer laundry appliance includes a recirculating process air flow system in fluid communication with a conditioning system for dehumidification and heating of the process air. The laundry appliance may be adaptable for use in a recreational vehicle with a water conservation mode setting for one or more laundry cycles. In the conservation mode, condensate water from a prior drying cycle is stored in a sump for use in a subsequent wash cycle.

A device for dryer vent includes a sensor node having a plurality of sensors, a base node that receives data transmission package from sensor node, a robotic device placed inside a robotic device housing. Base node on blockage detection communicates with the robotic device which is capable of autonomous traversal inside dryer vent to clean the dryer vent. A lint basket placed inside the robotic device housing is used by the robotic device to store lint removed from dryer vent during a cleaning cycle. A latch placed inside robotic device housing communicates with base node to allow the robotic device to enter or exit the robotic device housing during the cleaning cycle.

A method for a dry cycle calibration in a washing machine appliance. The method includes receiving an activation signal of a calibration cycle, performing, the calibration cycle in response to the activation signal. The calibration cycle including analyzing a cycle history of the washing machine appliance, measuring a first line voltage of an electrical supply line, monitoring a temperature via a temperature sensor of the washing machine appliance, measuring a load inertia and a second line voltage of the electrical supply line, and updating operational parameters in response to one or more of a line stiffness between the first line voltage and the second line voltage, the load inertia, and the temperature.
