WATER SERVER

摘要

A water server includes a pump which can lift water in an exchangeable raw water container into a water storage tank in a casing. The water server further includes a water level sensor in the form of a float sensor for detecting the upper limit and the lower limit of the water level in the water storage tank. The water server further includes a controller adapted to activate the pump upon receiving a sensor input indicative of detection of the lower limit, and deactivate the pump upon receiving sensor input indicative of detection of the upper limit. The controller is further adapted to measure the time elapsed since the pump was activated, and deactivate the pump when the time elapsed reaches a predetermined time at which the water level exceeds the upper limit and at which water in the water storage tank has not yet overflown the water storage tank.

主权项

1. A water server comprising;
a water supply line through which water in an exchangeable raw water container is drawn up to a water storage tank provided in a casing by means of a pump; a water discharge line through which water in the water storage tank is discharged; a water level sensor configured to detect an upper limit of a water level in the water storage tank and a lower limit of the water level; and a controller for controlling the pump, wherein the controller is configured to activate the pump upon receiving a sensor input indicative of detection of the lower limit, and to deactivate the pump upon receiving a sensor input indicative of detection of the upper limit, wherein the controller is further configured to measure a time elapsed since the pump was activated, and deactivate the pump when the time elapsed reaches a predetermined time at which the water level exceeds the upper limit and at which water in the water storage tank has not yet overflown the water storage tank.
