A home appliance system and an operation method thereof are disclosed. The home appliance outputs product information as a predetermined sound and transmits the sound through a connected communication network, thereby making it easier for a service center at a remote place to check a status of the home appliance. Further, the home appliance system and operation method thereof prevents noise or signal error generated in the procedure of converting product information into a signal of a predetermined frequency band in order to output the product information as a sound, thus enabling stable signal conversion and improving the accuracy of information transmission using the output of sound.

Home appliance, home appliance system, and diagnosis method of a home appliance

A home appliance and a home appliance system are provided. The home appliance may convert product information into an acoustic signal and externally output the same as a sound. The home appliance system may receive the sound, convert the same into the acoustic signal, and then inversely convert the acoustic signal into the product information and read the same. Accordingly, the home appliance may externally output the acoustic signal as the sound so that the user may be easily notified of transmission. Also, the home appliance system may easily transmit the sound to a management device to read the product information because the sound may be transmitted via a communications network.
