Boiled water heater

Abstract

The invention provides a boiled water heater. The boiled water heater comprises a water inlet 1, silicon rubber rings 2, a positioning plate 3, a stainless steel tube 4, connecting rods 5, temperature control installation blocks 6, a water outlet 7, a water outlet cover 8, seal rings 9, an electric heating tube 10, a temperature sensor 11 and a dry boiling preventing temperature controller 12, wherein the water inlet 1 and the water outlet 7 are connected by three connecting rods 5; the electric heating tube 10 has a double U shaped structure; the spread length of a heat emitting part of the electric heating tube is more than three times the length of the stainless steel tube 4; and the inner diameter of the stainless steel tube 4 is not more than 24mm. The boiled water heater has a complete structure, low electric heating tube surface load and small water volume, can achieve quicker boiled water outflow, is simple in assembly process, is safe and reliable, has stable properties and long service life and is an ideal instantaneous boiled water heater.
