Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of quick heating is provided, and firepower is strong, and adjustable extent is wide, and heat is imitated high, good heat insulating, and the stove silk life-span is long, and is pollution-free, the controlled adjustable electric cooking stove of economic power saving.
The purpose of this utility model is achieved in that a kind of controlled adjustable electric cooking stove, comprise electric furnace, shell, by shell, furnace internal-lining, stone or metal plate for standing a stove on as a precaution against fire, electric furnace heating wire, attaching plug, circuit board, rotary switch, high temperature flame-proof silk, safety pole, indicator lamp, wiring constitutes over the ground, shell is provided with the crossbeam of burner with stand inner bag, and the stone or metal plate for standing a stove on as a precaution against fire of indent places in the furnace internal-lining.
Described shell side is provided with louvre, and energising district is provided with protection network in it, and shell surface is provided with support, and more than at least three or three, its support is provided with stairstepping.
Described furnace internal-lining bottom is provided with perlite, and surperficial troweling layer is made by kaolin powder, mullite powder, asbestos wool and alkaline high-temperature adhesives.
The utility model quick heating, firepower is strong, and adjustable extent is wide, and heat is imitated high, good heat insulating, the stove silk life-span is long, and is pollution-free, set up switch especially, thoroughly cuts off the electricity supply, and avoids voltage instability, can start work under the unmanned state.Be provided with louvre on the shell side face, avoid because of the too high damage electric elements of components and parts operating temperature, energising district in bottom is provided with safety guard net, electric furnace heating wire is avoided easy fracture through specially treated in the stone or metal plate for standing a stove on as a precaution against fire, and the inner bag bottom is provided with perlite, reduces thermal losses, improve fuel factor, surperficial troweling layer is by kaolin powder, stone flour, asbestos wool, waterglass is made, and it is fried because of high anneal crack to reduce stone or metal plate for standing a stove on as a precaution against fire, and the shell surface layer is provided with pan straddle, support is provided with trapezoidal, increases container stability in use.This circuit just can be adjusted to 220V by 0V with voltage, owing to use the controllable silicon temperature adjustment, it is the potentiometer of 470K belt switch that potentiometer WTH-K adopts power, so it is big to have thermoregulation range, easy to operate, security performance height, advantages such as power intuitive display, controllable silicon BTH selects the import controllable silicon of 20A or 41A for use, and electric furnace heating wire can be selected 2000W～3000W for use.
