Water discharge device and method for controlling the same

A method for controlling a water discharge device including a case, a microphone configured to receive a sound input from a user, a voice recognition module configured to recognize voice information from the sound input, a speaker configured to output a guide sound to the user, a first elevation cover connected to the case, a second elevation cover configured to move upward relative to a bottom of the case and insert into an inside of the first elevation cover, an elevation motor connected to the second elevation cover and configured to provide power for operation of the second elevation cover, a water discharge nozzle disposed at a lower end of the second elevation cover and configured to dispense water, a water discharge valve configured to regulate a flow of water guided toward the water discharge nozzle, a flow sensor configured to sense a flow rate of the flow of water guided toward the water discharge nozzle, a sensor that is disposed at the second elevation cover, that has at least a portion exposed to a lower side of the second elevation cover, and that is configured to, based on the second elevation cover moving downward toward the bottom of the case, sense whether the sensor contacts a container disposed below the second elevation cover, the method comprising:

• receiving the sound input from the user through the microphone;
• recognizing the voice information from the sound input;
• recognizing an input wakeup word from the voice information, and outputting a wakeup word recognition guide sound through the speaker;
• recognizing a desired water discharge amount from the voice information, and outputting a desired water discharge condition recognition guide sound through the speaker;
• moving the second elevation cover downward toward the bottom of the case by operating the elevation motor;
• detecting whether the sensor contacts an upper end of the container;
• stopping operation of the elevation motor to stop a downward movement of the second elevation cover;
• opening the water discharge valve to discharge water;
• and
• closing the water discharge valve to terminate discharge of water based on an amount of discharged water corresponding to the desired water discharge amount, the amount of discharged water being determined based on the flow rate detected by the flow sensor.
