At this time, the controller 110 may perform the vibration test operation step by step at different rotational speeds.

In addition, the control unit 110 performs the noise test operation separately from the vibration test operation (S330). At this time, since the controller 110 generates noise by vibration, the noise test operation can be performed in parallel.

For example, if the vibration test operation is performed on the basis of the speed, the noise test operation can proceed based on the holding time for a certain rotational speed. That is, it is possible to measure the noise generated when the motor is maintained at a predetermined rotation speed for a predetermined time or more.

When the test operation is completed, the control unit 110 stores the data generated or measured during the test operation (S335). At this time, the data to be stored is data that is measured by the home appliance itself, and vibration and noise can be separately measured in the terminal 80 in the vibration or noise test operation as described above.

When the terminal is connected through the connection unit 130 or the communication unit 120 in operation S340, the control unit 110 transmits the stored data as operation state data to the terminal in operation S345.

On the other hand, if the test mode is not set, the control unit 110 performs the normal operation according to the setting inputted by the input unit 150 (S350).

The controller 110 stores data generated or measured during operation according to the setting (S360).

The terminal control section 81 outputs a predetermined guide through the output section 85 in accordance with the data to be measured as described above. At this time, the guide may be displayed including at least one of letters, numbers, and images, and may be output as a guide sound.

During operation of the home appliance 100, the terminal 80 measures and stores vibration and noise generated in the home appliance (S390). The terminal 80 also photographs home appliances. The terminal control unit 81 controls at least one of the vibration detection unit 87a, the noise measurement unit 87c, the microphone 89 and the camera 86 to operate and stores data to be measured or photographed.

After completion of the measurement, the terminal control unit 81 determines whether it is connected to the home appliance 100 through the communication unit 82 or the home appliance connection unit 83 (S400). When the terminal 80 is connected to the home appliance, the operating state data is received from the home appliance 100 (S405).

The terminal control unit 81 executes the diagnostic program, and diagnoses the state of the household appliances using the measured data and the received operation state data (S410).

On the other hand, if not connected to the home appliance, the terminal control unit 81 executes a diagnostic program and diagnoses the state of the home appliance using the measured data (S420).

When the diagnosis is completed, the terminal control section 81 outputs the diagnosis result (S430). At this time, the terminal control unit 81 transmits the diagnosis result to the household appliance when connected to the household appliance.

9 is a flowchart showing an operation method of a terminal connected to a service center after diagnosis for a home appliance.

Referring to FIG. 9, the terminal 80 performs the diagnosis of the home appliance using the measured data or the operation state data received from the home appliance (S450).

If there is an abnormality in the home appliance corresponding to the diagnosis result, the terminal control unit 81 connects to the service center 200 (S470) and transmits the diagnosis result to the service center (S480). In addition, the terminal control unit 81 requests the service center 200 for the service of the home appliance (S490).

As a result of the diagnosis, if the home appliance is in normal operation, the terminal control unit 81 outputs a guidance message indicating that the home appliance is in a normal state (S490).

As the home appliance and the terminal operate as described above, the data can be easily measured for the home appliance using the home appliance by installing the program on the terminal, and the state of the appliance can be checked and diagnosed. In addition, the service center can be connected according to the state of the home appliance, so that the AS is easy.
