There are several options of home-made electrical devices for cooking, made of “junk”, sometimes unfairly perceived as anything not suitable junk. For example, an outdated (if not leaky) metal pan. In the country and the shortage of time this is a very reasonable basis for a simple (cheap and reliable) electric. And the pot here is better suited to high — 140 mm or more. Becoming homemade design casing, it will be less warm. The handles of such tiles can be taken without any glove even after continuous hours of work — burns are excluded.
For mounting the burner in the center of the bottom of the pan drilled the hole for the pin M6 and on the corresponding delete (depends on the type of heater) chisel carved an opening under the terminal block. The size of the opening “a” and “b” is designed with maximum precision to reduce gaps in the Assembly.
For the ultimate simplification of the structure had to abandon electroisolators the degree of heating of the burner. And most power to turn of electrospray in parallel.
Another option is a homemade electric has a better shape. As housing used the metal cover from the magnetic starter. But it is better to weld sheet metal thickness of 0.8 — 1.5 mm. And sharp edges be rounded with a file. The corners at the bottom of the housing there is a special kerchief. Each hole with M6 thread. Here screw the bolts (with lock nuts) not only allow you to adjust the legs in height (and set the unit horizontally), but can also serve as a fastener for the removable bottoms (the latter is conventionally not shown).
Mount the burner does not differ from the previously discussed embodiment. Wiring better be solid copper wire (cross section 1 — 1.5 mm2) heat-resistant glass cloth insulation. For example, from the old household-type electric furnaces “Lysva”. In a pinch, you can use analog with rubber insulation.
Leaky pan as a hotplate in a hurry:
1 — housing; 2, 3 — stud, M6 nut, 4 — burner power 1 kW; 5 —capacity with prepared food; 6 — brick (4 PCs); 7 — terminal block burner; 8 — wire conductive heat-resistant insulation (2 PCs); 9 — cord with plug; 10 — the elastic insulating sleeve (from two to three layers of duct tape on a cotton-based wound at the point of passage of the cord through the hull); 11 — stand electric and heat insulation.
The unit with the housing made of sheet metal:
1 — body welded; 2 — leg installation (bolt M6 nut 4 PCs); 3 — burner power 1 kW; 4 — handle electric switch-regulator of heating of the burner; 5 — light (from the iron); 6 —screw M4 pan head slotted; 7 — cord with plug; 8 — the switch-regulator of heating of the burner (from the WEO-23-5230); 9 — solitaire (steel sheet of 1.5 s, 4); 10 — terminal block burners; 11 —stud M6 nut; 12 — a clamp (steel strip s1,8); 13 — nut M4.
The execution scheme of the wiring:
1 — terminal block burners; 2 — the switch-regulator of heating of the burner (from the WEO-23-5230).
Two tiles:
1 — body welded (steel sheet s1 ,5); 2 — leg installation (bolt M8 with lock nut, 4 pieces); 3 — burner power 1 kW (2 PCs); 4 — terminal connected to ground; 5 — disk support-protective (from old stove “Lysva” or “Tom”, 2); 6 — svetain-indicator (2); 7 — M4 screw with nut (2 PCs); 8 — cord with plug.
Additional controller function-power switch WEO-23-5230 when used in the design is that it serves as a kind of terminal block. To do this, Unscrew the screw at terminal 4. Then by loosening the retaining screw (opposite from the mounting side handle), delete from the cell with the findings of the “4” and “6” all that contributes to the appearance among them of an electrical contact. And after tightening the retainer screw to ensure complete isolation of the conclusions from each other.
Ease of use of light from an iron (light bulbs 3.5 V, connected to the ends of the small coils in series with the burner) not so much alarm to their inclusion in the grid, how many possible (the brightness of a light bulb) to judge the degree of heating of the working surface of the electric (amperage and output to the load power).
The third option is a homemade tiles — two. Here the output (the calculation takes the total value) twice, and aesthetics of performance higher than that previously considered. In particular, Svetovrachane bulbs in karbalievich cartridges-lanterns from a scrapped radio. A terminal for connecting the protective earth. And the installation of kilowatt burners are made in the image and likeness of a modern factory-produced stoves. This completely eliminates the leakage of oil and water on the terminals while cooking. By the way, the same mounting plates can be used in all the previously considered options of homemade electric stoves.
The case design is similar to the previous one.
