Abstract
Disclosed herein are a water purifying device and a method for controlling the same. The water purifying device is characterized in that a water discharge module capable of moving vertically is provided with a sensor. Specifically, in the water purifying device of one embodiment, the sensor may measure a height of a container, by transmitting and receiving a signal for measuring a distance at a first point of the water discharge module, and may detect both a height of the inlet of the container and a water level, by transmitting and receiving the signal and measuring a water level at a second point of the water discharge module.
Claims18
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.
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.
