Description

A kind of low-power electromagnetic stove

Technical field

The utility model relates to a kind of electromagnetic oven, is meant a kind of electromagnetic oven that can be controlled in work under the low input power state especially.

Background technology

Electromagnetic oven, its electromagnetic stove that is otherwise known as, it is the product of modern kitchen revolution, is the no fire that need not the heating of naked light or the conduction-type kitchen tools of cooking, and is different from all fire being arranged or do not have fire conduction heating kitchen tools of tradition fully.Electromagnetic oven is as a kind of novel kitchen range in kitchen tools market.It has broken the heating principle that traditional naked light cooking method adopts the magnetic field induction electric current, electromagnetic oven is to produce alternating magnetic field by the electronic circuit board part, when when containing irony pan bottom and place boiler face, pan promptly cuts the alternation magnetic line of force and is eddy current at the electric current that the pan bottom metal partly produces alternation, eddy current makes the random motion of pan iron molecule high speed, molecule runs foul of each other, friction and produce heat energy so, the thermal source that electromagnetic oven is cooked comes from the pan bottom rather than pan is given in electromagnetic oven heating conduction itself, so the thermal efficiency all exceeds nearly 1 times than the efficient of all cookers, thereby make utensil heating at a high speed voluntarily itself, be used for heating and cooking food, thereby reach the purpose of cooking.Have quick heating, thermal efficiency height, the flames of anger, no flue dust, no pernicious gas, to surrounding environment do not produce heat radiation, volume is small and exquisite, security good and advantage such as appearance looks elegant, the overwhelming majority that can finish family cooks task.

Mainly containing two large divisions's formation at textural electromagnetic oven is respectively electronic circuit part and structural packaged unit.Wherein, electronic circuit partly comprises: power amplifier board, motherboard, lamp plate, coil panel and temperature-sensitive support, fan motor etc.And structural packaged unit comprises: porcelain plate, plastic cement upper and lower covers, fan leaf, blower tray, power line, specification, power paster, operation film, the quality certification, plastic bag, shockproof foam, color box, bar code, carton.In concrete the use, the advantage of electromagnetic oven shows that at first its thermal efficiency is high.The application principle of electromagnetic oven is that electric current produces magnetic field by coil, when the magnetic line of force in the magnetic field passes through the bottom of iron compound (iron pan, stainless-steel pan, enamel pan etc.), impels the iron molecule high-speed motion, produces countless little eddy current, so thermal efficiency height.By contrast, the tradition stove and accessory is to burn directly food in the heating kettle of red vessel bottom earlier as the heating principle of electrothermal furnace, petroleum gas stove, gas burner and electric cooker, and other has portion of hot to consume at combustion air, the thermal efficiency is between 40%-70%, and the heat energy consumption is big, it is slow to cook.And the thermal efficiency of electromagnetic oven generally is higher than 80%, connects alliance's electromagnetic oven thermal efficiency and can reach 93%.Need 9 minutes with the boiled water flask of traditional cooking stove naked light, be put on the electromagnetic oven and then only need 2 ~ 3 minutes, saved the energy greatly.Connect alliance's electromagnetic oven be not subjected to pan kind and size about, the powerful system of exclusive heat energy is driven exploitation, the high calorific value that the electromagnetic oven of 2200W produces is equivalent to the high firepower that the gas burner of 4800KCAL/m3 sends.Secondly, the electromagnetic oven result of use is different fully with gas range, in use promptly can not produce naked light, and itself does not also generate heat boiler face, is not higher than the high-temperature component more than 250 ℃ in the body of heater, the accident of can not burning.Simultaneously, the heat-stable ceramic plate on electromagnetic oven surface, the metal pan that requires to be placed on above it must have enough contacts area just can produce heat energy, and is too small as contact area, then electromagnetic induction can not take place, and also just can not generate heat certainly.Can not cause burning even gasoline is sprinkled upon on the boiler face yet, will not often cause event of fire, more not have all disturbances that cause because of leakage gas as other kitchen range.When the magnetic line of force in the magnetic field passes through non-metallic objectsit is not a metal object, can not produce eddy current, so can not produce heating power.Boiler face and people are non-metallic objectsit is not a metal object, and itself can not generate heat, and wind more is not afraid of in the danger of therefore not burnt by electromagnetic oven, can not explode or cause gassing.When pan when boiler face is lifted down, electromagnetic oven also can be cut off the electricity supply automatically, we can say that electromagnetic oven is a kind of foolproof kitchen range.The operating frequency of general micro-wave oven is several gigahertzs, is harmful to health; And the frequency of oscillation of electromagnetic oven has only 20～30 kilo hertzs, and human body is not had any injury.Electromagnetic oven is provided with some kinds of safeguard protection electrical equipment, also has indicator lamp LED to show and automatics simultaneously, and the user is come into plain view, and accurately selects the different operating mode.Once more, heating power and cooking temp are controlled in the culinary art requirement that electromagnetic oven can be different according to the user flexibly and accurately.The input power of electromagnetic oven between 200W-2400W, can be selected to cook required temperature (constant temperature system) arbitrarily and temperature is set to a certain retaining usually.Why the cook can cook out delicious delicacies, and its major reason is that they can grasp the duration and degree of heating.Electromagnetic oven adopts advanced scientific method to develop from 0 to spend to a series of thermostat of 240 degree, and you can select required temperature when therefore cooking, and are very convenient, and the food that the cooking is come out reaches desirable color, smell and taste.At last, the all-round champion that electromagnetic oven is fried in shallow oil beyond doubt, fried, explodes, boils, stewes, this simple function than micro-wave oven is compared not have and is suspected to have great advance, and saves kitchen space to greatest extent, carries light and handy convenience, does not have the danger of radiation and electric leakage again.Compare with traditional charcoal, attractive in appearance, health, quick, safety, convenience can be rated as the best kitchen range of mutton cooked in a chafing pot.It is except as the mutton cooked in a chafing pot, steam, boil, fry in shallow oil, bake, explode, rinse, regularly, reservation, insulation be omnipotent, but a tractor serves several purposes like this is equivalent to 8 kinds of small household appliances.

But when we used electromagnetic oven sparking pot, we can be transferred to minimum to firepower usually after food boils, and the minimum heating power of common electromagnetic oven is 120 watts to 300 watts.Its power relatively all is bigger, so so owing to its power ratio must cause greatly existing waste of power resources.
