PURPOSE:To improve safety through prevention of discharge of steam bubbles, by a method wherein a large part is formed to a steam guide pipe running between a steam generating pipe and a discharge port, the steam guide pipe extending between the large part and the discharge port is formed in a non- rectilinear shape. CONSTITUTION:An electric heater comprises a heater unit 2, mounted to a front opening in a body case 1, a water tank 13 located below the heater unit, a steam generator 8, heating and boiling water stored in the tank, and a discharge port 18 through which steam generated from boiling is exhausted. A large part is formed to a steam guide pipe between the steam generating pipe 8 and the discharge port 18, and the steam guide pipe 8 between the large part and the discharge port 18 is formed in a non-rectilinear shape. Bubbles resulting from heating boiling are dispersed and decomposed by the steam generating pipe 8 to prevent increase of a water level, prevents projection of steam bubbles resulting from boiling, and provides an electric heater having high safety. |
