Abstract
A water purifier for killing bacteria in water located in a confined area includes a water inlet, a water outlet, and a purification unit that kills the bacteria in the water. A first fluid path is located between the water inlet and the water outlet so that water flowing along the first fluid path flows from the water inlet to the water outlet without passing through the purification unit, and includes a constricted region that has a cross sectional area that is smaller than a cross sectional area of the water inlet. A second fluid path is located between the water inlet and the water outlet, and includes the purification unit, so that water flowing along the second fluid path flows through the purification unit as the water flows from the water inlet to the water outlet. A self-adjusting flow regulator is positioned in the constricted region to automatically modify the cross sectional area of the constricted region to maintain a rate of flow along the second fluid path within a predetermined range as a combined rate of flow along the first and second fluid paths varies.
