Claim 17:
18. A method for controlling a liquid dispensing device comprising a main body, a liquid discharge module configured to move vertically at a front of the main body and to discharge the liquid, a controller, and a sensor installed in the liquid discharge module, the method comprising:
sensing first distance data at a first position of the liquid discharge module, by the sensor;
determining a height of the inlet of a container positioned below the liquid discharge module, by the controller and based on the first distance data;
controlling the liquid discharge module such that the liquid discharge module moves from the first position and down to a second positioned, at which the liquid discharge module is spaced upward from the height of the inlet of the container by a first distance, by the controller;
sensing second distance data when the liquid discharge module is at the second position, by the sensor;
determining a height of liquid contained in the container, by the controller and based on the second distance data; and
dispensing the liquid based on the height of the inlet of the container and the height of the liquid in the container, by the liquid discharge module, and
wherein the sensor moves together with the liquid discharge module to sense the first distance data al oi t the height of the inlet of the container at the first position and to sense the second distance data about the height of the liquid in the container at the second position.
