The present disclosure relates to an appliance having an input switch that receives a knock input at the front of a main body, and a transfer member connecting to the input switch that transfers vibrations caused by the knock to a sensor disposed at the rear of the main body.

A control method of an appliance, including: the appliance includes a first unit that includes a first lamp, a first cavity, a first door and a first sensor; a second unit that includes a second lamp, a second cavity, a second door and a second sensor; and a controller that controls operations of the first unit and the second unit, includes sensing vibrations generated in any one of the first unit or the second unit by the first sensor and the second sensor; determining whether the sensed vibrations are caused by a knock, and when determining that the sensed vibrations are caused by a knock using the first sensor and the second sensor, transferring a knock-on signal to the controller; and comparing the knock-on signals received from the first sensor and the second sensor and determining which of the first unit or the second unit is given the knock by the controller, and outputting a lamp-on output signal to the first unit or the second unit in which the knock is generated by the controller.

The present disclosure relates to an appliance. The appliance includes; a main body that has a first accommodation space therein, and a first sensing module that is disposed at the main body in a way that the first sensing module is disposed outside the first accommodation space. Since a sensor is disposed to avoid the effect of heat as described above, the sensor is much less likely to operate improperly or be broken because of heat.

A clothes dryer includes a cabinet having a front surface with an opening in the front surface; a drum inside the cabinet and configured so that objects to be dried are insertable through the opening to be received in the drum; a heat exchanger; and a door to open and close the opening, and including a ventilation member, wherein the door is configured so that, with the door being in an open state, the ventilation member covers at least a portion of the opening so that the ventilation member prevents objects in the drum from moving through the opening, air passing through the heat exchanger is discharged from the drum, through the ventilation member and the opening, to an outside of the cabinet, and outside air is supplied through the ventilation member and the opening to the heat exchanger.

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 dryer including a drum; a heat pump including a compressor, evaporator, condenser, and electronic expansion valve; a user interface; a power module to control power supply to the compressor motor and the drum motor; a duct to receive air from the drum so that the received air flows in the duct to be heated by operation of an evaporator and condenser, and to discharge the heated air to the drum; a plurality of temperature sensors to detect temperature of the heat pump, the power module, and the duct; and a controller configured to identify a factor to be controlled from among a plurality of factors that may cause incomplete drying, based on at least one of output data from the plurality of temperature sensors and opening degree data of the electronic expansion valve, and control the user interface to output a notification of the identified factor to be controlled.

A dryer appliance includes a microphone for monitoring sound generated during operation of the dryer appliance and a controller is operably coupled to the microphone. The controller is configured for obtaining a sound signal generated during operation of the dryer appliance and converting the sound signal into a spectrogram that represents a sound frequency and a sound amplitude over time. An artificial intelligence image recognition process is used to analyze the spectrogram to identify one or more sound signatures that are associated with particular operating conditions, and operation of the dryer appliance is adjusted based at least in part on the identification of the sound signature.
