Abstract: A rapid heating, highly efficient and reliable hot water drinking apparatus comprises: a water machine (1); a tank (2); a water boiler (3); a funnel (4); a liquid level switch (8); a salver (9); and a weight sensor mechanism (91). Said potable water heating device is characterized in that: three heating devices (31) are disposed inside said water boiler (3), said heating device (31) consists essentially of a hot-resistant chamber (32), whose one opening is connecting to the tank (2) and the other opening is connecting to the funnel (4); a cap (33) covering one opening of said chamber (32); a hyperthermal electric heating tube (34), disposed axially inside said chamber (32), whose one end is protruded through said cap (33); and a baffle (35), disposed helicoidally on the exterior of said heating tube (34).
