摘要
A water supply unit to ensure that drinking water, which is transferred from a drinking water connection to the water-consuming parts of a dentist's unit, is not polluted, consists of an upper container (1) which is connected with a lower container (2) via a valve (3), which has a large opening. In addition, the upper container is provided with an overflow (14), where water may be transferred via the overflow (14) to an outlet/overflow via an outer container (5) which surrounds the upper container (1) and the lower container (2).;Drinking water is supplied to the upper container (1) and the lower container (2) by the opening of valves (3, 6).;Since the upper container has the overflow (14), there will always be an air gap between the water level at the edge of the overflow (14) and the outlet/overflow of a pipe (27), said pipe (27) being connected with the valve (6). This ensures that the drinking water will never be polluted, since the water from the valve (6) cannot get into contact with the water in the upper container (1).;In an embodiment, the upper container (1) is connected with a chemical reservoir (22) via a pump (7) or a reservoir and a valve (16).;In addition, the water supply unit has a control unit (26) which adjusts the supply of drinking water and optionally chemical.
