Description
Technical field
The utility model relates to household electrical appliance electromagnetism heating products and makes the field, specifically is meant a kind of small-power high energy efficiency electromagnetic coil disk of electromagnetism heating products core component.
Background technology
What the electromagnetism heating products was the most frequently used is electromagnetic oven, has another name called electromagnetic stove, is the product of modern kitchen revolution, and it need not naked light or conduction-type heats and let heat directly produce in the bottom of a pan, so the heat efficiency is greatly improved.Electromagnetic oven is the electric cooking apparatus that utilizes electromagnetic inductive heating principle to process.Partly form by high-frequency induction electromagnetic coil disk, RF power conversion equipment, controller and ferromagnetic material the bottom of a pan cooker etc.During use, feed alternating current in the electromagnetic coil disk, just produce an alternating magnetic field around the coil, the magnetic line of force of alternating magnetic field is most of through the metal pan body, in the bottom of a pan, produces a large amount of eddy current, thereby produces the required heat of culinary art, reaches the purpose of cooking.Have quick heating, heat efficiency height, the flames of anger, no flue dust, no pernicious gas, to surrounding environment do not produce thermal radiation, advantages of small volume, fail safe is good and advantage such as appearance looks elegant, the overwhelming majority that can accomplish family cooks task.
Because electromagnetic oven produces eddy current by the direct induced field in the bottom of a pan and produces heat, therefore should select irony (stainless steel) cooker that meets the requirement of electromagnetic oven design load for use, the cooker of other materials is excessive or too small owing to resistivity of material, cisco unity malfunction.Simultaneously because iron is abundant to the absorption in magnetic field, shield effectiveness is also very good, has reduced a lot of magnetic radiations like this, so iron pan is also all safer than the cooker of other any materials.In addition, iron is the material useful to health, also is the essential elements that human body need absorb for a long time.
The core component of electromagnetic oven is an electromagnetic coil disk; It is the power output element of electromagnetic oven; Be about the pulse current that 20KHz, electric current are about 20A by the IGBT power tube to its frequency of delivery, make irony (stainless steel) cooker that is arranged on the electromagnetic coil disk top produce powerful eddy current and heating.
Existing electromagnetism heating products; Owing to many-sided reasons such as manufacturing technologies; Great majority are two kilowatts and above high-power, large-sized product, and such product is used for the culinary art of family or unit three meals in a day, and is no problem certainly; It is just improper to be used for small household appliances, and to be that volume is too big cause heating greatly with efficient is low to main cause.Small household appliances such as boiler, soy bean milk making machine, coffee heater etc. still adopt the electrical bar heating at present.There are problems such as efficient is low, cleaning difficulty, electric leakage in the electrical bar heating.
Therefore, research and development small size small-power high energy efficiency electromagnetic coil disk, it is imperative to make the small power electromagnetic heating products.
Summary of the invention
In order to solve the problems referred to above that prior art exists, the utility model provides small-power high energy efficiency electromagnetic coil disk.
The technical scheme that the utility model uses is following:
A kind of small-power high energy efficiency electromagnetic coil disk comprises coil and magnetic patch, and said magnetic patch is made up of magnet ring and magnetic sheet, and said coil is one deck, three layers at the most at least, between coil and magnetic sheet, is provided with mica sheet.
The material of said coil is an enamelled wire, adopt spiral press close around mode by the lining and outside form double-layer structure.Enamelled wire is an enamel covered wire, and its resistance is low, material property is good, and coil is provided with two lead-out wires.
Said magnet ring is an integral structure, perhaps is made up of two to eight arc magnetic sheets; Said magnetic sheet is the hollow integral structure, perhaps is made up of two to ten arc magnetic sheets.Usually magnet ring and magnetic sheet all are integral structure.
Said magnetic sheet, magnet ring, mica sheet, coil are the centre junction formula structure that is integrated with the axis.
Above-mentioned spiral press close around mode by the lining and outer form double-layer structure, adopt two kinds of methods formation:
1, earlier close, then close along diametric(al) again outside diametric(al) is reached by the lining around the second layer around ground floor;
2, first close first lap around ground floor, close again the first lap and second circle around the second layer are turned one's head close second circle and the 3rd circle around the second layer again, and the rest may be inferred, until whole close around completion.One circle is the girth of a circle.
Above-mentioned first method close around coil, the layer with layer between not tight, easy separation; Preferred second method close around coil.
The beneficial effect of the utility model is:
1) magnetic patch adopts the magnet ring and the magnetic sheet of integrative-structure, and the heat efficiency is increased to 95% by 90% of prior art; Can prevent alternating magnetic field to external radiation, improve the reliability and the fail safe of Electromagnetic Control plate and circumferential component.
2) coil be one deck above and adopt spiral press close around mode by the lining and outside form, can in limited size, bring into play maximum heating power, the heater block temperature is even, working stability.
3) between coil and magnetic sheet, mica sheet is set, plays insulation, heat-blocking action, improve the reliability of the utility model.
