Abstract
A water purifier or other liquid dispenser may sense a height of the inlet of a container accurately through an infrared transmitter and an infrared receiver that are disposed at different positions of a water discharge module moving vertically. Additionally, in the water purifier, the water discharge module may discharge purified water at a point spaced a certain distance apart from the inlet of the container, based on infrared sensing, thereby preventing the inlet of the container from contacting the lower surface of the water discharge module.
Claims14
A liquid dispenser, comprising:
- a main body;
- a liquid discharge module including a nozzle to discharge a liquid to a container, the liquid discharge module being configured to move the nozzle vertically at a front of the main body;
- a connecting wall connected to the liquid discharge module and configured to move vertically along with the liquid discharge module;
- a first infrared transmitter configured to transmit first infrared rays and provided at a one of a lower surface of the liquid discharge module or a first end of the connecting wall;
- and
- a second infrared transmitter provided at the front of the main body and configured to transmit second infrared rays,
- wherein a speed of a downward movement of the liquid discharge module is determined based on a receipt intensity of the second infrared rays.
