Abstract
A drinking water dispenser heats and cools drinking water supplied from a water supply bottle, and provides heated and cooled drinking water. The dispenser includes a cold water tank, a hot water tank, a water supply pipe, a valve, a by-pass pipe, a by-pass valve and a control unit. The valve opens and closes a water outlet for taking in the drinking water from the water supply bottle according to a level of the drinking water in the cold water tank, limits supply of the drinking water to the cold water tank, and, while the water outlet is shut, suppresses convection of the drinking water and/or heat of the drinking water between the water supply bottle and the cold water tank.
