Summary of the invention
The purpose of this utility model is to provide the electromagnetism that a kind of magnetic dispersion is few, magnetic radiation is little, the heat efficiency is high drum, to overcome deficiency of the prior art.
To achieve these goals, electromagnetism drum of the present utility model is reached by the following technical programs:
A kind of electromagnetism drum comprises wire coil rack and coil, and described coil q Q value is higher than 3, disperses to be provided with graininess or pulverous magnetic thing in the described wire coil rack.
Described magnetic thing is the ferrimagnetism thing.
The proportion of described magnetic thing and wire coil rack is smaller or equal to 80%.
Described electromagnetism drum also is provided with magnetic stripe.
Another purpose of the present utility model is to provide a kind of electromagnetic stove, to achieve these goals, electromagnetic stove of the present utility model is reached by the following technical programs: a kind of electromagnetic stove, comprise loam cake, lower cover, panel and electromagnetism drum, described electromagnetism drum comprises wire coil rack and coil, described electromagnetic stove power is 800W-3500W, disperses to be provided with graininess or pulverous magnetic thing in the described wire coil rack.
The utility model is by directly increasing the mode of magnetic thing in wire coil rack, make wire coil rack itself serve as the effect of original magnetic stripe, therefore can cancel magnetic stripe used in the prior art, such electromagnetism drum is after energising, because the effect of magnetic thing is assembled the magnetic line of force, thereby the magnetic line of force that leaks around the electromagnetism drum reduces, thereby the lifting heat efficiency reduces magnetic dispersion, reduces electromagnetic radiation.In addition,, can reduce cost, also reduce the operation of assembling magnetic stripe owing to can cancel the setting of magnetic stripe; Wire coil rack squeezes into wire coil rack with injection moulding mode straight forming or by the external force fashion of extrusion with the magnetic thing, with respect to prior art, and easier processing.In addition, the utility model also reaches with easy technology and significantly promotes efficiency, less magnetic dispersion, the purpose of reduction electromagnetic radiation; Simultaneously can also reduce production cost and material cost.
