Abstract
In a water purifier or other liquid dispenser, a sensor configured to transmit and receive a distance measuring signal is installed in a water discharge module moving vertically or disposed at the front of a main body, to sense a height of the inlet of a container accurately without a no-response duration of the sensor. Additionally, in the water purifier, the water discharge module discharges purified water at a point spaced a certain distance apart from the inlet of the container, to prevent the inlet of the container from contacting the lower surface of the water discharge module.
Claims20
A liquid dispenser, comprising:
- a main body;
- a liquid discharge module including a nozzle at a lower surface thereof to discharge a liquid, and configured to move the nozzle vertically along a front of the main body;
- and
- a sensor provided inside one of the main body or the liquid discharge module, and configured to transmit a signal to the container and to receive a reflected signal from the container,
- wherein the sensor is positioned to be spaced a predetermined distance apart from a corresponding one of a front of the main body or a lower surface of the liquid discharge module, the predetermined distance being greater than or equal to a length of a dead zone of the sensor to prevent the container from being positioned within the dead zone.
A liquid dispenser, comprising:
- a main body to provide a liquid;
- a liquid discharge module including a nozzle to discharge the liquid to a container and to vertically move along a front of the main body;
- a connector arm including a first end connected to the liquid discharge module so the connector arm moves vertically along with the nozzle of the liquid discharge module;
- and
- a sensor provided at a second end of the connector arm, and configured to transmit a signal and to receive a reflection of the signal,
- wherein the connector arm positions the sensor below the inlet of the container and between the main body and the container when the liquid discharge module is vertically positioned to dispense the liquid.
