Detailed Description

The present invention will be described with reference to the following embodiments.

Referring to fig. 1 and 2:

a steam generator comprises a metal water tank 1, wherein a tank cover 5 with a steam exhaust hole is arranged at the top of the metal water tank 1.

The metal water tank 1 is a square tank body, the top parts of two corresponding sides of the metal water tank are provided with outer folded edges 101, and the electric heaters 2 are symmetrically arranged in the folded angles of the outer folded edges 101 on the two sides.

The bottom of the metal water tank 1 is provided with a water replenishing pipe 3, and a ball valve 4 for automatically opening and closing the water replenishing pipe 3 to control the water level in the tank is arranged in the tank, so that the water level stored in the tank is maintained below the electric heater 2.

The electric heater 2 comprises a heat conducting plate 201, a plurality of rod grooves are arranged on the top surface of the heat conducting plate 201 in parallel, an electric heating rod 202 is arranged in each rod groove, the heat conducting plate 201 is surrounded by a support 203 and is fixed on the outer wall of the metal water tank 1, and the top surface of the heat conducting plate is attached to the bottom surface and the inner side surface of the outer folded edge 101 and is attached to the outer side wall of the metal water tank 1.

The heat generated by the electric heater 2 during operation is conducted downwards from the top of the metal water tank 1, the heat is firstly conducted to the contact line between the metal water tank 1 and the water surface of the water stored in the tank, and the function of only heating the water body at the contact line into water vapor can be realized by controlling the heating time of the electric heater 2.
