Abstract
The utility model relates to a coil disk wound with an enamel and copper insulated aluminium wire and an enamel insulated aluminium wire for an electromagnetic stove, which is characterized in that a coil flat wound by enamel insulated wire bundles is surrounded by an enamel and copper insulated aluminium wire or an enamel insulated aluminium wire; the coil flat wound by enamel insulated wire bundles is arranged on a supporting frame of the coil disk; a soft magnet is arranged in the supporting frame of the coil disk of an electromagnetic oven, and the enamel and copper insulated aluminium wire is formed by that insulating varnish is coated around a copper layer after 10%-15% copper as a conductive body is covered around an aluminium core wire. The enamel insulated aluminium wire is formed by that the insulating varnish is coated on the aluminium core wire. The coil disk using the technical scheme has the advantages that the weight of the coil disk of the electromagnetic oven is effectively reduced, cost can be effectively reduced, the heating area of the electromagnetic oven on a cooker is effectively enlarged, heating is uniform, and the opportunity of pasting and burning a pot is reduced; the temperature of the coil disk can be effectively lowered, the safety of the electromagnetic oven is enhanced and the service life of the electromagnetic oven is prolonged.
Description
Affiliated technical field:
The utility model relates to a kind of coil disc of electric stove.
Background technology:
The coil of current coil disc of electric stove all adopts enamel covered wire coiled coil, adopts this kind coil to have the shortcoming of following four aspects: the one, and pot heating area is little; The 2nd, it is inhomogeneous to generate heat, and the local cold and hot temperature difference is big; The 3rd, easily sticking pot or burnt; The 4th, the cost height, electromagnetic oven is not long useful life.
The utility model content:
It is relatively large that the purpose of this utility model provides a kind of and pan heating area, heating evenly, cost is low, can prolong electromagnetic oven useful life, increases the electromagnetic coil disk of electromagnetic oven fail safe.
For achieving the above object, the utility model is by the following technical solutions: the utility model constitutes (seeing accompanying drawing 1) by the coil of coil bracket, soft magnet, the flat coiling of enamel-cover wire harness, sleeve pipe, terminal etc., the coil of the flat coiling of enamel-cover wire harness by enameled copper clad aluminum line or enamel insulated aluminium wire in same plane around forming; The coil horizontal of the flat coiling of enamel-cover wire harness is on coil bracket; Soft magnet is installed in the coil disc of electric stove support, and electric current can produce the alternation magnetic line of force by the coil on the coil panel, and the magnetic line of force forms electromagnetic circuit at pan on the electromagnetic oven and the soft magnet on the coil panel, thereby forms the operating state of electromagnetic oven.
The enameled copper clad aluminum line be cover about 10%-15% around the aluminum core line copper as conductor, coat insulating varnish in copper layer periphery again and form.Enamel insulated aluminium wire is to coat insulating varnish to form on aluminum core line.
After adopting above technical scheme, this scheme is compared with the coil panel that adopts enamel covered wire and is had the following advantages: the one, can effectively reduce coil disc of electric stove weight, obtaining under the situation of substitutional resistance, it is about 42% that copper-clad aluminum conductor can reduce weight, and enamel insulated aluminium wire can reduce weight 52%.Copper aluminium density ratio is respectively 8.93 and 2.7; The 2nd, can effectively reduce cost; The aluminium unit price is about 50% of copper.The 3rd, can effectively increase the heating area of electromagnetic oven on pan, increase by 57%, under the constant situation of coil inductance, copper-clad aluminum conductor and aluminum steel must strengthen the line footpath or increase number because of pursuing substitutional resistance, and wire harness strengthens, because of flat around, aluminum bronze resistivity ratio is 0.027: 0.017=158.8%.So increased area coil 58.8%, and the place that electromagnetic oven only has coil to produce the magnetic line of force just can make pan produce heating, so heating surface (area) (HS is bigger.Thereby whole electromagnetic oven heating is more even, has reduced sticking pot and burnt chance; The 4th, can effectively reduce by 20 ℃ of coil panel temperature, because of area coil wideer, so electromagnetic oven fan area of dissipation is wideer, so coil temperature is lower.Actual measurement and low about 20 ℃ down of enamel covered wire coil panel equal conditions.Increase the fail safe of electromagnetic oven, thereby prolonged the useful life of electromagnetic oven.
Description of drawings:
Fig. 1 is a backsight structural representation of the present utility model;
Fig. 2 is a main TV structure schematic diagram of the present utility model.
Embodiment:
The utility model will be further described for the contrast accompanying drawing below:
As shown in Figure 1, electromagnetic oven enameled copper clad aluminum line, enamel insulated aluminium wire coil panel are made of the coil 2 of coil bracket 1, the flat coiling of enamel-cover wire harness, sleeve pipe 3, terminal 4, soft magnet 5 etc., the coil 2 of the flat coiling of enamel-cover wire harness by enameled copper clad aluminum line or enamel insulated aluminium wire in same plane around forming; Coil 2 horizontal of the flat coiling of enamel-cover wire harness are on coil bracket 1; Soft magnet 5 is installed in the coil disc of electric stove support 1, and electric current can produce the alternation magnetic line of force by the coil on the coil panel 2, and the magnetic line of force forms electromagnetic circuit at pan on the electromagnetic oven and the soft magnet on the coil panel 5, thereby forms the operating state of electromagnetic oven.The enameled copper clad aluminum line be cover about 10%-15% around the aluminum core line copper as conductor, coat insulating varnish in copper layer periphery again and form.Enamel insulated aluminium wire is to coat insulating varnish to form on aluminum core line.
