Claim 0:
1. A liquid dispensing device, comprising:
a main body;
a liquid discharge module configured to discharge a liquid to a container and to move vertically at a front of the main body;
a controller configured to control a vertical movement of the liquid discharge module, and to determine a height of an inlet of the container and a level of the liquid contained in the container based on received distance data; and
a sensor installed in the liquid discharge module and configured to sense the distance data a d transmit the distance data to the controller,
wherein the controller is configured to determine the height of the inlet of the container based on first distance data, of the distance data, that is sensed when the liquid discharge module is at a first position and to control the liquid discharge module such that the liquid discharge module moves to a second position that is spaced upward from the height of the inlet of the container by a first distance, and
wherein the controller is configured to determine the level of the liquid based on second distance data, of the distance data, that is sensed when the liquid discharge module is at the second position, and
wherein the sensor moves together with the liquid discharge module to sense the first distance data about the height of the inlet of the container at the first position and to sense the second distance data about the level of the liquid at the second position.
