How to make an electric stove with your own hands — homemade electric stove
Electric stove with power control
Such a homemade electric stove with power adjustment is easy to make with your own hands. It is necessary to purchase only a tubular burner made of two heating elements with a tube diameter of 10 mm (Fig. 1).
Fig. 1. Tubular burners of electric stoves:
a — from two heating elements (the type suitable for our purposes); b — from a single–end heating element; c — from a two-end heating element.
The adjustment of the power of the burner (247, 450, 550 and 1000 watts) is carried out without a multi-position switch (the most expensive part of the electric stove) using three conventional power sockets and an electric jumper (Fig. 2). The power sockets are mounted on the body of the electric stove or installed separately (in the form of a block).
Fig. 2. Options for connecting heating elements:
a — total power 247 watts; b — total power 1000 watts.
The plate body (Fig. 3) is made of a steel sheet 0.8...1 mm thick. The dimensions of the case are 245x195x100 mm. It is equipped with four legs, three holes for M5 screws are drilled from the end and on the sides (for fixing the ring-shell. In the lid (of the appropriate size) cut down (drilled) the hole is 155 mm in diameter. On the front end of the housing there are holes for fixing electrical outlets, and on the sides there are holes for electric cords of heating elements.

The burner is installed using a shell (a ring bent from steel with a thickness of 1 mm). Ring diameter — 155 mm, height — 40...45 mm. A groove or recess (100x30 mm) is cut out in the ring for the outlet of the ends of the heating element tubes, as well as three radial grooves for fixing the burner, on which three plates are fixed for this purpose, radially converging to the center of the burner. To fix the burner in the housing, three holes are drilled in it for M5 screws. Place the burner 4...6 mm above the lid. To increase the efficiency of the burner, a spherical reflector is installed under it in the housing, for example, a cut-off hood from a car wheel. The reflector is fixed with an M4 screw M5.
Short lengths of an electric cord are attached to the ends of the heating element tubes (for example, from an old electric iron, with forks (see Fig. 3). The general electric cord is selected long enough. In order to avoid short circuits, porcelain tubes or cups are strung on the connecting ends of the electric cords. Housing electric stoves are painted with a heat-resistant varnish, for example, «Thermoxyl».
