A home appliance is provided. The home appliance includes a main controller for generating a first data signal including status information and a second data signal including operating information, a first sound output device for outputting a first sound signal according to the first data signal including status information to be transmitted through a communication network, and a second sound output device for outputting a second sound signal according to the second data signal including operating information to be perceived by a user. Thus, the sound signal regarding the status information and the sound signal regarding the operating information can be output through the different sound output devices, i.e., the first and second sound output devices.

Home appliance

A control method of a washing machine enables the output of a plurality of melodies indicative of any one of a plurality of operational states of the washing machine. The method of controlling the washing machine includes the steps of assigning at least one audio signal according to a specific operational state of the washing machine among a plurality of operational states, monitoring the specific operational state of the washing machine, and outputting the at least one audio signal according to the specific operational state.

Washing machine with melody generating assembly

A dryer is disclosed. The dryer includes dryer includes a door opening sensing unit sensing an opening of a door, a heater heating air provided in a drum, and a microcomputer determining an error in the heater based on an internal temperature condition of the drum, which changes in accordance with a driving time of the heater, and setting a new driving time of the heater, when the door is open before the driving time of the heater being counted reaches a predetermined driving time.

Dryer and method for controlling the same

A control method and system for a belt-driven clothes dryer are disclosed. The control system includes a drum containing a load of wet clothes to be dried, a heater heating air flowing into the drum, a motor coupled to the drum by a power transmission system for rotating the drum, and a power supply supplying power to the motor and the heater during a dry operation of the dryer. The control system further includes a moisture sensor outputting a sensor signal during the dry operation, or a photo coupler outputting voltage pulses when the motor is in operation during the dry operation. Then, a microprocessor included in the control system detects a breakage of the power transmission system upon analyzing the sensor signal of the moisture sensor or the voltage pulses generated by the photo coupler. If the microprocessor detects such breakage, it interrupts the dry operation of the clothes dryer.
