Abstract

The invention discloses an electric cooker capable of automatically controlling input power. An electric cooker cover is designed into double-layer stainless steel, and a layer of cotton is clamped between stainless steel; both the cooker cover and an inner cooker are designed into six concave-convex interphase wiredrawn edges; an annular cowheel rubber tube is arranged in the cooker cover; the cooker cover and the inner cooker are closed; and when cooking, the rubber tube expands to ensure that hot air in the cooker can not escape out of the cooker. On the basis of the common electric cooker circuit, a thermistor, a charging and discharging capacitor, a bilateral diode, a quick fuse wire and a bi-directional triode thyristor are additionally arranged to control the circuit of a heating element. When temperature in the cooker reaches the set temperature, the resistance of the thermistor quickly increases to prolong charging time, thus greatly shortening the conducting time of the heating element, automatically reducing the input power, and achieving the purposes of automatically adjusting consumption power and saving electricity energy to the utmost.

Description

Energy-saving electric cooker

Affiliated technical field

The present invention relates to cook in a kind of kitchen, stew, the device of cooking, especially can save the electric cooker of a large amount of electric energy.

Background technology

At present, known electric cooker, after the water boiling in the pot, the high-power heating during still with beginning, heat loses from pot cover, pot body, wastes a large amount of electric energy, also forms the part of greenhouse effects.

Summary of the invention

Waste the deficiency of a large amount of electric energy in order to overcome existing electric cooker, patent of the present invention provides a kind of electric cooker, and it not only avoids heat to scatter and disappear, and saves electric energy, and the meal of making, dish, soup are tasty, nutritious.

The technical solution adopted for the present invention to solve the technical problems is: pot cover adopts the dome-shaped double-layer stainless steel, therebetween skim cotton, be used for insulation, the internal layer stainless steel is silver-plated, on the circumference of pot cover, pot cover and interior pot contact position all make concavo-convex alternate six wiredrawn edges, and a Cowhells rubber pot circle is arranged in the pot cover wiredrawn edge.Cook indicator lamp, current-limiting resistance series connection back parallel resistance, electric capacity heating element heater series thermal-sensitive in parallel again resistance, charge and discharge capacitance fuse in parallel, bidirectional thyristor, connect the at last parallel connection of temperature control switch, temperature limit switch, insulation indicator lamp string current-limiting resistance, bilateral diode is connected between thermistor and the bidirectional thyristor; Timer of series connection on circuit can the scheduled time, and then circuit is connected, and cooks.When beginning to cook, the resistance of thermistor is very little, and the charging interval of electric capacity is very short, and heating element heater heats with whole power; When water temperature reached 100 ° in the pot, the external thermistor resistance of pot increased rapidly, and the charging interval of electric capacity prolongs, and heating element heater heats with small-power; When the temperature in the pot reached 108 °, temperature control switch, temperature limit switch all disconnected, and the insulation indicator lamp is bright, and heating element heater is incubated with micropower.Because pot cover, pot body dispersed heat are few, micropower can keep temperature not descend.

The beneficial effect of patent of the present invention is, can avoid scattering and disappearing of heat, realizes that the water temperature in the pot remains on about 100 ° automatically, can keep the nutritional labeling of food not run off.Simple in structure.
