Description
Technical field
The present invention relates to a kind of electric hot tray in electric heating cooking utensil field, particularly a kind of electromagnetic electrothermic dish.
Background technology
All the time, the resistance wire electric hot tray is because of conducting heat evenly, and cooking quality is good, and price is low, by electric heating cooking utensil extensive uses such as electric rice cooker, electric pressure cookers.The operation principle of resistance wire electric hot tray: spiral resistance wire heating power heating electric hot tray, again by electric hot tray with heat, pass to the pan that is placed on unlike material on the electric hot tray, heating is contained in the food in the pan.The resistance wire electric hot tray is as the important devices of electric rice cooker, electric pressure cooker etc., its production technology is, spiral resistance wire is potted in the metal tube with magnesia powder, after again the canal curvature of the good resistance wire of embedding being become required shape, with die casting, be cast into the blank electric hot tray, at last the blank electric hot tray is carried out turning processing and surface treatment.
To electric rice cooker invention in last century, what the resistance wire electric hot tray adopted always is above-mentioned production technology, this manufacture, and energy resource consumption is big, seriously polluted, and production efficiency is low.Continuous development along with electronic technology, emerge " electric hot tray that is used for the family expenses fill container " of the patent No. 200320118257, patented technologies such as " electric hot traies " of the patent No. 200620041436, make every effort to by changing the production method of electric hot tray, keeping the resistance wire electric hot tray conducts heat evenly, the effective advantage of cooking, solve the casting of resistance wire electric hot tray again, the problems that occur during die casting is produced, but because of failing to break away from basic resistance wire heating principle, therefore, the change of production technology is although solved some production problems, but still can not solve the resistance wire electric hot tray, use power low, power is non-adjustable, the deficiency that thermal losses is big.
The development of electromagnetic technique is with ripe, for the electric heating cooking utensil has brought vigor and vitality.The electromagnetism cooking apparatus has been broken traditional resistance wire heating principle, utilizes the high frequency alternation magnetic line of force to act directly on the pan with cutting magnetic line characteristic, and the pan cutting high frequency alternation magnetic line of force produces eddy current, makes the purpose of pot body heating realization to the food heating.The electromagnetism cooking apparatus mainly is made up of devitrified glass ceramics panel, fuselage cover, coil panel, control circuit board, fan five major parts, and coil panel then is made of stranded enamelled wire, plate rail, magnetic conductor.
Electromagnetic technique can combine with electronic technology well, has the flames of anger, safe in utilization, the efficiency height, power is big, advantages such as scalable, but cooking pot tool must possess the attribute of " cutting magnetic line ", and the magnetic line of force is to directly act on pan to produce heat, not only restricted the use that does not have cutting magnetic line attribute pan, simultaneously in use, the thermal conductivity that cause has cutting magnetic line attribute pan is low, the heat that eddy current produces is concentrated again and is acted on the food, so that when cooked rice or paste like food, very easily take place to stick with paste the end, and bad phenomenon such as half-cooked appear again in the not good position of heat conduction at the pan heat place of concentrating.In sum, no matter be resistance wire electric hot tray cooking apparatus independently, still in producing, using, always there is unsatisfactory problem in electromagnetism cooking apparatus independently.
Summary of the invention
The object of the present invention is to provide a kind of new technical scheme, electromagnetic technique and resistance wire electric hot tray technology are combined together.Draw the electromagnetic technique flames of anger, safe in utilization, power is big, watt level is easily regulated, combine and resistance wire electric hot tray heat transfer advantage of uniform with electronic technology is easy, when solving resistance wire electric hot tray energy consumption height, polluting problem such as heavy, that efficient is low, use that power is low, power is non-adjustable and thermal losses is big, it is strong to cooking pot tool material selectivity to have solved electromagnetic technique, heat concentrates place's food easily to stick with paste at the end, and the half-cooked deficiency that waits appears again in heat conduction not Jia Chu easily.
For achieving the above object, technical scheme of the present invention is:
A kind of electromagnetic electrothermic dish, comprise by heat dish (1), carriage (2), having that coil panel (3) is formed produces high-frequency alternating magnetic field and the magnetic heat dish (60) that cuts the high frequency alternation magnetic line of force, and the transducer (40) that produces the high frequency alternating current, it is characterized in that: hot coil (1), carriage (2), coil panel (3), magnetic heat dish (60) is formed in stack, and magnetic heat dish (60) is connected with transducer (40) by the lead-out wire (31) of coil panel (3);
Described magnetic heat dish (60) is made up of heat dish (1) that is separately fixed at carriage (2) two sides and coil panel (3) stack;
The shape of described heat dish (1) can be a convex, also can be concavity, can also be plane;
Described heat dish (1) can be a part independently, also can be installed on the thermal conductor (11) by heater (10) and form;
Described carriage (2) is made by material that can not cutting magnetic line, and carriage (2) is installed the one side of coil panel (3), and the inboard is provided with the erection column (21) of fixed coil dish (3), and the outside is provided with feet (22);
The described heater (10) of forming heat dish (1) is made by the material that can cut alternation magnetic line of force generation eddy current, be shaped as plane, thermal conductor (11) is made by the good material of conductivity of heat, the shape that thermal conductor (11) is not installed heater (10) one sides can be a convex, also can be concavity, can also be plane;
Installed inside post (21) and lateral branch spike (22) more than 2 or 2 are arranged on the described carriage (2).
Beneficial effect of the present invention is: by integrate the electromagnetic technique flames of anger, safe in utilization, power is big and adjustable, easily combine with electronic technology and the resistance wire electric hot tray uniform advantage of conducting heat, pan with the magnetic line of force of the cut alternation in the electromagnetic technique, heat dish (1) the cutting high frequency alternation magnetic line of force that is transformed into by the electromagnetic electrothermic dish produces eddy current, heat hot dish (1), by heat dish (1) heat is passed to the pan of unlike material equably again, realize indirect food.So both solved that the resistance wire electric hot tray is produced and use in, the energy consumption height, pollute problems such as heavy, that production capacity is low, power is low, power is non-adjustable, it is strong to cooking pot tool material selectivity to have overcome electromagnetic technique again, the undesirable deficiency that waits of cooking quality.
