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 via a communicator of a diagnostic server and extracting product information about the home appliance from the sound signal;
analyzing via the diagnostic server the product information and determining, when an error code is set in the product information, whether the error code corresponds to a dryer heater error associated with a dryer heater of the home appliance;
diagnosing via the diagnostic server a fault of the home appliance by determining, when the error code corresponds to the dryer heater error, whether the dryer heater or a drying fan of the home appliance is out of order using diagnostic data associated with operation of the dryer heater among a plurality of diagnostic data included in the product information; and
deriving via the diagnostic server a diagnosis result by deriving a solution corresponding to a cause of the dryer heater 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, determining, when a drying error has occurred, a cause of the drying error, and deriving a solution to the drying error. 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.

15. A home appliance diagnostic system, comprising:
-
a home appliance having a dryer heater that outputs product information required for fault diagnosis as a sound signal; a diagnostic server that receives the sound signal, derives a state, a fault, and a fault cause of the home appliance, and as a diagnosis result, a solution to the fault; and a portable terminal that receives the sound signal output from the home appliance and transmits 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 dryer heater error associated with operation of the dryer heater of the home appliance based on the product information, and diagnoses a fault of the home appliance by determining, when the error code corresponds to the dryer heater error, whether the dryer heater or a drying fan of the home appliance is out of order using diagnostic data associated with the dryer heater among a plurality of diagnostic data included in the product information, and then derives a solution to the fault of the home appliance. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
