Home appliance diagnosis system, and method for operating same

摘要

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.

主权项

1. A home appliance, comprising:
a selection device that receives input of an instruction to perform a failure diagnosis; a memory that stores product information of the home appliance for the failure diagnosis; a controller that changes a mode of the home appliance to a smart diagnosis mode, encodes the product information stated in the memory and generates the product information into a control signal formed with a plurality of frames, when a fail diagnosis execution instruction is input by the selection device; a modulator that generates a predetermined frequency signal to correspond to the control signal; and an audio output driven by the modulator to output a sound to correspond to the frequency signal, wherein the controller comprises:
a main controller that controls to display a progress state of a smart diagnosis mode through a display, when entered into a smart diagnosis mode by an input to the selection device; andan encoder that generates the control signal by encoding the product information to a control signal of a predetermined format, wherein the encoder sets an IFS, which is a segment in which a signal is not output for a predetermined time period, between the plurality of frames.
