On the induction cooker

1. the principle of

Induction cooker is used current (and said Eddy) of heating principle, that through electronic circuit board produced high frequency current, by rectifier circuit will 50 HZ/60HZ of Exchange electric into DC voltage, again after control circuit will DC voltage conversion into frequency for 20-40KHz of high frequency voltage, through spiral-like of magnetic induction circle, formed high induction cooker frequency make variable magnetic field, dang magnetic field within of lines through iron magnetic material vessels bottom, in its body produced make variable of current (that Eddy), Eddy makes pot with iron molecular High speed random motion of molecules collide, generated by friction heat can itself its own high-speed heating (electric energy as heat), used for heating and cooking, so as to achieve the purpose cooking.

Because induction cookers rely on pot induced magnetic fields generate eddy currents directly heat, therefore should be used with induction cooker design requirements of iron (iron) cooking utensils and other Cookware material is too large or too small, can cause abnormal load and start the automatic protection, does not work. Absorption of iron due to the full, the effect is very good, this reduces the number of magnetic radiation, so the wok cookers are also more than any other material. In addition, the body's long-term need to ingest the necessary and beneficial to health.

2. structure

Also known as induction cooker, is a product of modern kitchen revolution, without requiring an open flame or conduction heating and directly in the pot, so the thermal efficiency has been greatly increased. Is a highly efficient energy-saving kitchen, completely different from the traditional conduction heating kitchen all fire or no fire. Induction cooker is made using the principle of electromagnetic induction heating electric cooking appliances. By high frequency induction heating coil (coil), high frequency power conversion devices, controllers and ferromagnetic pot cookware and other parts.

There are two main components: one part is the ability to produce high-frequency alternating magnetic field lines system (including the Induction coil); It is also used in fixed electronic circuit system, the structural shell and carrying the pot (including the furnace Panel can withstand high temperatures and hot and cold blast crisis).

(1) electronic circuit system include: Power Board, Board, light Board (control display panel), temperature control, coil and thermal support, fans, and so on.

(2) structural shell include: furnace Panel (and Crystal), plastic cover;

(3) manuals, power stickers, action film, certificate of plastic bag, shock-proof foam, packaging, bar code, card box.

1, Panel: used to carry pots, imported and domestically produced, made a, b has been able to meet demand.

2, base unit: constitutes the main current circuit.

3, base unit: for computer-controlled functions.

4, circuit board: display working status, and delivery instructions.

5, wire: high frequency alternating electric stream into an alternating magnetic field ().

6, fan Assembly: thermal auxiliary components (FAN), lower furnace temperature of the components inside.

7, commonly known as power tubes, low current signals to control high current switching (IGBT).

8, bridge rectifier block: to convert AC power to DC power (BD101).

9,: heat signal will be passed to the control.

10, thermal switch Assembly: sensor temperature, thereby protecting IGBT damage due to overheating

3. characteristics

Induction coil under the control of low frequency (20~25KHZ) alternating magnetic field, through magnetic (ferrous) Pan produces a lot of intensive, and induced currents into heat to heat the food, extra high. Using the iron, special or iron pans of baked enamel, and the bottom diameter of 12~26 cm is appropriate. Induction cookers are attached to prevent overheating, power-saving and safe.

1, heating speed---induction cooker Pan temperature rises to more than 300 degrees for 15 seconds, speed is much faster than oil furnaces and gas furnaces, greatly reduce the cooking time, improve the speed of course.

2, energy saving and environmental protection – induction cookers no fire, body heating, reducing transmission losses, so the thermal efficiency can reach over 80% to 92%, and no emissions, no noise, and greatly improved the kitchen environment.

3, multi-function---induction cooker ' fried, steamed, boiled, stewed, Shabu ' total. , A new family of three general use induction cooker, basically replaced the gas stove, gas main shower.

4, easy to clean---there are no residual induction cooker and air pollution, so the pot, are very easy to clean, this is unthinkable in other stoves.

5, high security---induction cooker does not like that, easily leaks, do not produce an open flame, and significantly better security than other stoves. In particular, there are multiple safety protection measures of its own, including tilt the furnace off, time-out power cuts, police at burning, over current, over voltage, under voltage protection, improper use of automatic shutdown, and so on, even when the soup spills, gas stove flame deflation danger does not exist, use hassle free. Especially the stove panels and thermal radiation, danger does not exist, the elderly and feel more at ease.

6, easy to use:---civil cooker ' key actions ' indicates very human, old small children saw it, coupled with the furnace itself is only a few pounds heavier, and take it to either not a problem, as long as it is used everywhere there is power. Bedroom cramped working personnel in the field, when it pulled out from under the bed, again in it, what stoves can have such facilities?

7, economical---induction cookers are energy hogs, but due to rapid heating, electricity prices are relatively low, calculation, cost more than gas, gas is cheaper. In addition, 1600W cooker minimum price of just more than 100 Yuan, but also sent the pot.

8, reduces investment---commercial induction cooker much less than traditional stoves needed kitchen space, because there is no combustion exhaust gases, so some reduction in investment in drainage devices, and from the gas pipeline construction and ancillary costs.

9, precise temperature control---induction cooker can precisely control the cooking temperature, both energy and make sure the food is delicious, it is important to promote conducive to production standard Chinese dishes.
