As described in the background art, for improving electromagnetic stove performance or the thermal efficiency, those skilled in the art are usual
The mode improving electromagnetic wire coil (such as, solenoid or magnetic stripe) can be taked to realize.But, this
A person of good sense finds, the distance of electromagnetic wire coil (especially solenoid) and panel the most also can shadow
Ring the performance to electromagnetic stove, the particularly thermal efficiency；In general, when other parameter or condition are identical, electricity
When magnet-wire dish distance panel is nearer, the thermal efficiency of electromagnetic stove can be higher.Thus, for improving electromagnetic stove thermal effect
Rate, the design that inventor proposes is to try to the distance furthering between electromagnetic wire coil and panel；This is very
In big degree, verified by experiment and practice.
But, when panel and electromagnetic wire coil be designed to be close to certain degree time, the assembling meeting of electromagnetic stove
Go wrong.Reason is, aborning, the actual size of device always can with its design size (or
Claim standard size) there is error；When the installation site of electromagnetic wire coil is designed to be with the installation site of panel
Time sufficiently close together, the error in manufacture or when assembling, the electromagnetic wire coil of installation usually will be made to enter
The installation site of panel, so causes panel to install and puts in place, or the panel breakage electricity installed by force
Magnet-wire dish, causes electromagnetic stove normally to work.Which kind of the most above-mentioned situation, all can largely effect on electricity
The yield rate of magnetic stove.
The approach solving the problems referred to above is constantly to improve the accuracy of manufacture of equipment, installation accuracy, but this
