Description

Energy-saving electric stove for cooking rice

The utility model relates to home-use category.

Popular in the market electric cooker exists and can only boil meal dry and can not cook congee (overflowing easily when cooking congee), and power consumption is too many.

The purpose of this utility model is the function that will enlarge electric cooker, using electricity wisely again simultaneously.

Characteristics of the present utility model:

Shell is made of bell 1 and housing 2, orlop is a heat-insulation layer 12 in the housing, be placed with heater 6 on the heat-insulation layer, topped insulating barrier 5 is placed heat-conducting plate on the heater on the insulating barrier, and pot 3 is placed on the heat-conducting plate, insulating barrier one side is equipped with temperature sensor 7, relay 8 is equipped with by the housing wall place in its below, is embedded with Gear-shift switch 9 on the furnace wall and power switch 10,11 is power supply lead wire and plug.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Describe content of the present utility model in detail below in conjunction with accompanying drawing.

1, the 2nd, the bell of electric meal stove and housing, it is made with metal material or with engineering plastics, in fill out with aluminium silicate wool or poly-third ethylene foam plastic, its existing good heat preservation property has the good insulation performance performance again like this.3 for pot is a kind of common pot of heating of family expenses, comprise enamel enamelware pot, aluminum pot, marmite, porcelain pot, stainless-steel pan,, glass enamelware pot or other metal pan.

4 be heat-conducting plate it with galvanized iron sheet or corrosion resistant plate or aluminium alloy plate.Its function is heat conduction, makes boiler face heating evenly, and it bears the pressure in the bottom of a pan and often contacts with the bottom of a pan simultaneously, so requirement has suitable rigidity and wearability.

5 is insulating barrier, and its function is to guarantee to make on the heat-conducting plate not charged, and the dielectric strengths of tolerance more than 3000 volts are arranged between heat-conducting plate and the power firestreak, generally makes with mica sheet.

6 is heater, can select for use a kind of thermo electric material to make arbitrarily, for example heating wire, Electric radiant Heating Film, DZR heating or the like.

7 is temperature sensor, adopts bimetal plate temperature controling switch.Temperature detect switch (TDS) action when temperature in the stove reaches 90 ℃～95 ℃, starting relay.

8 is relay, adopts four blade double-throw, withstand voltage 500 volts, the relay of rated current 5A, is used for switching the electrical power of electric heating body, express train is heated grade make the shelves of heating fast or at a slow speed into.

9 is Gear-shift switch, before electric meal stove temperature in stove reaches 95 ℃ all with express train heat shelves heat treat to have after the actuating of relay add soon gentleness heat slowly two grades available, user's plate as required moves gear switch and selects.

10 is power switch, controls the on/off of electric meal stove.

11 is power supply lead wire and plug.

The source reason of electricity meal stove electronic temperature control part:

Can overflow when why ordinary electric rice cooker cooks congee? because temperature reaches 101～105 ℃ of ability tripping power supplys in electric cooker.And power is too big, be in the pot when cooking congee stream mode, the bottom of a pan does not reach 105 ℃, therefore being in very hot oven burning result all the time must overflow, if but temperature limiter is just being moved less than 100 ℃, cook congee like this and can not overflow, boiling meal dry will be half-cooked, the bad solution of this a pair of contradiction.

The utility model temperature controlling method, it is temperature detect switch (TDS) action when temperature reaches 95 ℃ in the pot, relay switches the power of heater, power or small-power shelves rather than cut off the electricity supply in changing into by high-power shelves, even so owing to temperature in the good heat insulating small-power shelves pot of electric meal stove still raises until boiling slowly, big fire is urged and being rolled, little fire is cooked rice over a slow fire, big fire is urged and being rolled, and it all is to be in a kind of splendid state that little fire is cooked gruel.

Heater 13 is that two and half heaters are coupled to an integral body, does not promptly inhale heater R when the relay J before 95 ℃ of temperature in the stove remains static ₁R ₂Be in state R in parallel ₁=R ₂So its general power is (E ²)/(R ₁)

After temperature in the stove reaches 95 ℃, relay J adhesive, heater R ₁And R ₂Be in series connection, fall to (E under its power ²)/(R ²+ R ₂) i.e. 1/2 (E ²)/(R ₁)=4 times

The difference of power is before and after 95 ℃

$\frac{\frac{E^2}{R_1}}{\frac{1}{2}\frac{E^2}{R_1}}$

K in the accompanying drawing 2 ²Be Gear-shift switch, if switch places slow shelves, the electric current by heater after the relay adhesive will be through a diode halfwave rectifier, and power reduces by half again, and its difference power will differ 8 trainings.For example urge and only need cook rice over a slow fire or cook gruel after being rolled into 95 ℃ with 40W power with 320W.K in the accompanying drawing 2 ₁Be power switch, K ₃Be temperature detect switch (TDS).

Advantage of the present utility model and good effect:

Multi-functional, can boil meal and gruel dry, cooking congee can be unattended and do not have the sorrow of overflowing, and easy to use, family's pot commonly used all can be put into stove and hot plate. Burning in the general culinary art, boil, endure, stew, boil in a covered pot over a slow fire, simmer, stew and all can be finished by it, power saving is economized on electricity one times than ordinary electric rice cooker, and its thermoelectric conversion ratio can reach on 80%; Safety is used in pollution-free, the flames of anger.
