A method of operating a laundry appliance may include a step locking the laundry appliance. The method also may include a step of projecting acoustic waves. The acoustic waves may be modulated to carry an indicium of the laundry appliance. The acoustic waves may be projected by the laundry appliance. The method may also include a step of receiving the acoustic waves by a remote user interface device. The method may further include creating a session of the laundry appliance. The method may additionally include activating the laundry appliance after creating the session of the laundry appliance.

A system for controllably releasing humid air including a washing unit having a housing; a washing drum within the housing; a port defining a first opening operable to intake air from an outside atmosphere into an internal cavity of the washing drum; a vent defining a second opening operable to direct the air to flow out of the internal cavity of the washing drum; and a release pipe with a first end coupled to the vent and a second end terminating on an exterior of the washing unit to enable the air to flow out of the vent to an exterior of the housing. The system also includes a damper positioned within the release pipe operable to open or close the release pipe to release humidity to the outside atmosphere and a processor configured to communicate with an external measurement device and operable to selectively open or close the damper.

A method for controlling a laundry treatment includes performing, by the lower treatment device, a washing course including a water supply step, a washing (rinsing) step, and a dehydration step, and performing, by the upper treatment device, a drying course including a hot air supply step, a fan operation step, and a dryness sensing step. The lower treatment device performs the washing course by changing a configuration of at least one of an operation of the tub heater, an execution time of the washing course, and an operation of the lower driver according to a progress state of the drying course, thereby performing the washing course.

In a laundry treatment apparatus including a cabinet having an opening formed in one side thereof, a door rotatably coupled to the cabinet to open and close the opening, a drum rotatably provided inside the cabinet and configured to accommodate laundry introduced through the opening, a door lock unit provided inside the cabinet and configured to lock the door when the door closes the opening or release a locked state of the door in order to open the opening closed by the door, a communication unit configured to receive remote inputs of a user for communication with an external device, and a switch unit configured to connect or disconnect an external power, a locked state of the door and connection to the external power are maintained while a user maintains remote control after a preset cycle including rotation of the drum is performed.

A laundry appliance includes a cabinet. A drum disposed within the cabinet and has an inner circumferential wall. At least one lifter is operably coupled to the inner circumferential wall of the drum. A motor is operably coupled to the drum and is disposed within the cabinet. A controller is disposed within the cabinet and is communicatively coupled to the motor. A negatively-charged member selectively disposed within the drum. A negative charge is configured to attract oppositely-charged foreign substrates to the negatively-charged member. The negatively-charged member is selectively coupled to the at least one lifter.

An apparatus includes at least one of an actuator or a heater, and a controller that controls the at least one of the actuator or the heater. The controller: obtains an application defined by a plurality of blocks that drive the at least one of the actuator or the heater, each of the plurality of blocks including a parameter for driving the at least one of the actuator or the heater; consults a first rule that defines a first parameter range within which the at least one of the actuator or the heater is not permitted to be driven, and modifies the application by changing at least one block included in the plurality of blocks, the at least one block including a parameter included in the first parameter range; and drives the at least one of the actuator or the heater based on the modified application.
