Referring to FIG. 4, if the water or ice discharge function is not selected through the display device 120, the water discharge valve (not shown) of the water tank 40 and the ice discharge valve of the ice maker 50 are not shown. O) is closed (S11).

The refrigerator controller 140 determines whether the display device 120 is separated from the accommodation groove 110 (S12).

First, when it is determined that the display apparatus 120 is separated from the accommodation groove 110, the refrigerator controller 140 switches to the voice information recognition mode and detects the voice through the voice input unit 134 (S13). In this case, switching to the voice information recognition mode may be implemented by switching a driving circuit.

If the voice information is not recognized by the voice input unit 134, the refrigerator controller 140 maintains the voice information recognition mode.

In addition, when the user says 'ice ice', when the voice input unit 134 recognizes voice information (S14), the voice recognition unit 133 converts the voice information into a frequency (S15). At this time, the voice information is converted into an analog frequency to a digital frequency.

In addition, the refrigerator control unit 140 determines whether the converted frequency and the frequency previously stored in the refrigerator memory unit 132 match (S16).

However, when it is determined that the frequencies do not coincide with each other, the water discharge valve and the ice discharge valve of the ice maker 50 are kept closed (S11). Thus, the ice or water can be discharged only when the user speaks a specific command.

On the other hand, if it is determined that the converted frequency and the frequency previously stored in the refrigerator memory unit 132 (S16), the refrigerator control unit 140 controls to open only the valve corresponding to the matched frequency (S17). At this time, the refrigerator control unit controls to open only the ice ice discharge valve.

When it is determined that the open valve is opened for a predetermined time (S18), the open valve is closed (S19). Thus, ice discharge from the dispenser is stopped.

Next, when it is determined that the display apparatus 120 is mounted in the accommodation groove 110, the refrigerator controller 140 switches to the voice and input information recognition mode (S21). Then, the voice and input information are sensed through the voice input unit 134 and the input unit 122 of the display apparatus 120 (S22). Switching to the voice and input information recognition mode can be implemented by switching the driving circuit.

If it is determined that the voice information is not recognized by the voice input unit 134, it is determined whether the input information is recognized through the input unit 122 (S23).

At this time, if it is determined that the input information is not recognized, the refrigerator control unit 140 maintains the voice and input information recognition mode. On the other hand, if it is determined that the input information is input, the refrigerator control unit 140 controls to open a valve corresponding to the input information (S24). For example, when it is determined that the ice cube button is pressed, the refrigerator controller opens the ice cube discharge valve.

When it is determined that the open valve (ice discharge valve) is opened for a predetermined time (S18), the refrigerator control unit 140 closes the open valve (S19).

When it is determined that the voice information is recognized by the voice input unit 134 (S22), the refrigerator controller 140 converts the voice information into a frequency (S15). At this time, when the user says 'ice ice', the speech recognition unit converts the voice for the 'ice ice' into a frequency.

In addition, the refrigerator controller 140 determines whether the converted frequency and the frequency previously stored in the refrigerator memory unit 132 match (S16).

At this time, if it is determined that the frequencies do not match, the water discharge valve and the ice discharge valve of the ice maker 50 is maintained in a closed state (S11). Thus, the ice or water can be discharged only when the user speaks a specific command.

On the other hand, if it is determined that the converted frequency and the frequency previously stored in the refrigerator memory unit 132 match, the refrigerator controller 140 controls to open only the ice ice discharge valve corresponding to the matched frequency (S17).

When it is determined that the open valve is opened for a predetermined time (S18), the refrigerator control unit 140 closes the open valve (S19).

Of course, when the display device is separated from the receiving groove, when the user says 'water' or 'flake ice', water or flake ice may be discharged as described above.

According to the present invention, since ice or water can be discharged from the dispenser by voice while the display device is separated from the door, the present invention is remarkably industrially applicable.
