ABSTRACT:
The present invention relates to a desktop drinking water machine and includes a reverse osmosis mechanism consisting of a reverse osmosis filter and a pair of active carbon filters. The reverse osmosis mechanism is linked to a pump through an inlet pipe, a pure water pipe connected to a reservoir and an outlet pipe connected to the original reservoir where both pipes link the original reservoir to the pump. A water level sensor in the reservoir is linked with the pump through a processor to control a water pumping operation. When the water level rises above the water level sensor, the pump is initiated and delivers water from the reservoir into the reverse osmosis mechanism. Pure water then flows into the storage tank and waste water flows to the reservoir. When the volume of the water in the reservoir is approximately one-third of the volume of the original water maintained in the reservoir, the pump is deactivated. At this time, the purified water contained in the storage tank approximates two-thirds of the volume of the water in the reservoir which provides for an increased purifying rate.
