Apparatus for supplying hot water for coffee brewing purposes
Abstract
Abstract A hot water tank has a hot water discharge pipe extending from a siphon chamber through the bottom and terminating in a discharge head. A cold water receiving basin is telescoped with the upper part of the tank, has a peripheral flange overlying the upper end of the tank, has the siphon chamber on its underside and a cold water discharge pipe opening near the bottom of the tank. A thermostatic control device, located in the path of the cold water from the cold water discharge pipe, controls the energization of an electric heating element located in the lower part of the tank. A metallic baffle overlies the electric heating element to retard the mixing of the incoming cold water with the hot water above the baffle, to act as a safety shield, and to facilitate the transfer of heat to the water in the upper part of the tank.
