DIAGNOSTIC SYSTEM AND METHOD FOR HOME APPLIANCE
First Claim
1. A diagnostic method for a home appliance diagnostic system, the method comprising:
- receiving a sound signal output from a home appliance and extracting product information about the home appliance from the sound signal;
analyzing the product information and determining, when an error code is set in the product information, whether the error code corresponds to a water supply error associated with a water supply operation of the home appliance;
diagnosing fault of the home appliance by determining, when the error code corresponds to the water supply error, whether at least one of water supply malfunction, water level sensor malfunction, and program malfunction has occurred using diagnostic data associated with the water supply operation among a plurality of diagnostic data included in the product information; and
deriving a diagnosis result by deriving a solution corresponding to a cause of the water supply error, the cause being obtained according to the fault diagnosis.

Abstract
A diagnostic system and method for a home appliance is provided. When the home appliance outputs product information as a sound signal, a service center remotely performs fault diagnosis of the home appliance by receiving the sound signal, detecting the product information from the sound signal, checking the state of the home appliance using diagnostic data included in the product information to determine whether the home appliance is out of order, diagnosing, when water supply malfunction including a water supply error or a water level sensor error has occurred, a cause of the water supply malfunction, and deriving a solution to the water supply malfunction. Upon deriving a diagnosis result through the fault diagnosis of the home appliance, the service center immediately notifies the user of the diagnosis result and may dispatch a service technician or may provide the user with a solution to allow the user to easily fix the fault without dispatching a service technician.

9. A home appliance diagnostic system comprising:
-
a home appliance for outputting product information required for fault diagnosis as a sound signal; a diagnostic server for receiving the sound signal, deriving a state, a fault, and a fault cause of the home appliance, and deriving, as a diagnosis result, a solution to the fault; and a portable terminal for receiving the sound signal output from the home appliance and transmitting the sound signal to the diagnostic server through a communication network, wherein the diagnostic server determines, when an error code is set in the product information extracted from the received sound signal, whether the error code corresponds to a water supply error or a water level sensor error based on the product information, and diagnoses fault of the home appliance by determining, when the error code corresponds to the water supply error or the water level sensor error, whether at least one of water supply malfunction, water level sensor malfunction, and program malfunction has occurred using diagnostic data associated with a water supply operation among a plurality of diagnostic data included in the product information, and then derives a solution corresponding to a cause of an error associated with the water supply operation and outputs a diagnosis result. - View Dependent Claims (10, 11, 12, 13)
