Home appliance, home appliance system, and diagnosis method of a home appliance
First Claim
1. A home appliance that transmits product information to a management device via a communication network for fault diagnosis of the home appliance, the home appliance comprising:
- a selection device that receives an input of an external command signal;
a storage device that stores the product information of the home appliance for the fault diagnosis;
a controller that, upon receipt of the external command signal through the selection device, loads the product information stored in the storage device and generates a control signal including the loaded product information as a sequence of symbols;
a conversion device that converts the control signal into a sequence of acoustic signals, each of the acoustic signals having any one of predetermined frequencies which are different from each other from signal to signal; and
an output device that receives the sequence of the acoustic signals from the conversion device and outputs a sound corresponding to the sequence of the acoustic signals, wherein each of the acoustic signals corresponds to each of the symbols, and the controller controls signal conversion of the conversion device to be stopped during a dead time provided between adjacent symbols, and wherein the each of the symbols corresponds to 1 bit.

Abstract
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.

12. A diagnosis method of a home appliance, the diagnosis method comprising:
-
storing product information of a home appliance; upon receipt, in the home appliance, of an external signal for diagnosis, loading the product information; generating a control signal including the loaded product information as a sequence of symbols, each of the symbols corresponds to 1 bit; converting the control signal into a sequence of acoustic signals, each of the acoustic signals having any one of predetermined frequencies which are different from each other from signal to signal; and outputting the sequence of the acoustic signals as a sound, wherein each of the acoustic signals corresponds to the each of the symbols, and wherein converting the control signal is stopped during a dead time provided between adjacent symbols. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

21. A home appliance that transmits product information to a management device via a communication network for fault diagnosis of the home appliance, the home appliance comprising:
-
a selection device that receives an input of an external command signal; a storage device that stores the product information of the home appliance for the fault diagnosis; a controller that, upon receipt of the external command signal through the selection device, loads the product information stored in the storage device and outputs a control signal including the loaded product information as a series of bits, each bit having a value of 0 or 1; a conversion device that converts the control signal into modulated output signals based on frequency, wherein adjacent bits of the modulated output signals are modulated based on a different frequency; and an output device that receives the modulated output signals from the conversion device and outputs a sound corresponding to the modulated output signals, wherein when adjacent bits of the modulated output signals have different bit values, the controller controls the conversion device such that a dead time is provided between the modulated output signals, wherein each of the modulated output signals corresponds to 1 bit of the product information.
