Abstract
Coffee or tea maker has an intermediate vessel for holding heated water, a siphon for periodically emptying the intermediate vessel into a coffee or tea filter, a ventilation pipe for venting the intermediate vessel, and a water inlet for filling said intermediate vessel with heated water. The intermediate vessel is closed except for the siphon, the ventilation pipe, and the inlet pipe. There is a siphon inlet on an upper part of the siphon and which extends upwardly further than a lower delimiting plane on a lower portion of a downwardly open chamber located within the intermediate vessel. The ventilation pipe opens into the downwardly open chamber for venting air therefrom, and the lower delimiting plane lies below the overflow edge of the siphon inlet for preventing air from entering the downwardly open chamber when the water level in the intermediate vessel is at least at the level of the lower delimiting plane for preventing further venting of air from the intermediate vessel for enhancing siphoning by the siphon.
