HOME APPLIANCE DIAGNOSIS SYSTEM, AND METHOD FOR OPERATING SAME
First Claim
1. A home appliance comprising:
- a selection unit for inputting an instruction for performing a failure diagnosis;
a memory for storing product information of the home appliance for the failure diagnosis;
a controller for changing a mode of the home appliance to a smart diagnosis mode and for encoding the product information stored at the memory and for generating the product information into a control signal formed with a plurality of frames, when a failure diagnosis execution instruction is input by the selection unit;
a modulator for generating a predetermined frequency signal to correspond to the control signal; and
an audio output unit driven by the modulator to output a sound to correspond to the frequency signal,wherein the controller comprises;
a main controller for controlling to display a progress state of a smart diagnosis mode through the audio output unit when entered a smart diagnosis mode by an input to the selection unit; and
an encoding unit for generating the control signal by encoding the product information to a control signal of a predetermined format.

Abstract
The present invention relates to a home appliance diagnosis system and to a method for operating same, wherein product information is output in a predetermined signal sound by a home appliance product, and the signal sound is transmitted via a communication network connected to a remote service center to enable the service center to easily check the state of the home appliance product. In addition, the product information is encoded into a predetermined format and modulated to enable sound to be outputted by the home appliance product, thereby preventing noise or signal errors. The present invention enables stable signal modulation and accurate sound output, and enables the easy recovery of the sound transmitted to the service center via the communication network.
