【摘要】：IH(Induction Heating)电磁加热技术发明之后,是目前最先进的电饭煲加热方式,彻底地解决了加热盘的几大弊端。IH技术的工作原理,即,通过电磁线圈来接通交变电流,从而直接对金属内胆来进行加热,因此,越过了加热盘的热量传导过程,使得升温变得较为迅速。而且有很多高端的IH电饭煲种,引入了多级线圈,实现了对整个内胆的环绕加热,并且实现了绝对的均匀加热。本项目通过对IH电饭煲的磁场及热场分布仿真,研究现有的IH电饭煲在不同参数和配置下产生的磁场分布情况,以及变化的磁场分布对热场分布的影响。在仿真前构造标准化的模型,以来验证仿真效果。这种利用建造模型来重现实际系统中发生的本质过程,并且通过对系统模型的一系列实验来研究存在的或设计中的系统,又称为模拟。而在这里所谈到的模型,包括物理的亦或数学的,静态的亦或动态的,连续的亦或离散的,等等各种模型。在仿真过程中,能够将磁场分布可视化,并能对仿真结果定量测量。同时能够根据磁场强度和负载材质计算热场分布并可视化,能够自定义不同结构配置参数,能够计算线圈盘模型在不同电参数下的磁场强度。还可对不同配置的方案可以做效果对比(可视化的效果及对比数据)。在仿真相关数据时,自定义的参数计算模型有相应的测试数据及理论支持文档。此外,仿真模型绘制支持常规的画图工具(CAD和Pro/E)输出的文件格式,仿真效果图能够输出供office文件使用,能够输出激励源变化时的动态变化云图效果。同时,采用编程技术,设计相应程序,展示操作界面。通过使用ANSYS,Ansoft Maxwell等仿真软件、SolidWorks等绘制软件以及Visual C++编程软件达到这些课题研究目的,可对实物进行深一步的探究,更全面掌握各个细节以及内部功能,完善产品,提高效益。充分掌握对建模软件、仿真软件的熟练应用,对实物进行模拟仿真,从而得出有效结论,并将其应用到生产实践中,为其实现提供依据与理论基础。
[Abstract]:After the invention of electromagnetic heating technology, IH(Induction heating is the most advanced heating method for rice cookers. The working principle of IH technology is solved thoroughly, that is, the alternating current is connected by electromagnetic coil, and the metal inner tank is heated directly. Over the heat transfer process of the heating disk, the heating becomes more rapid, and there are many high-end IH rice cooker species, the introduction of multi-stage coil, to achieve the entire tank around the heating. Through the simulation of the distribution of magnetic field and thermal field of IH rice cooker, the distribution of magnetic field produced by existing IH rice cooker under different parameters and configurations is studied. And the influence of the changing magnetic field distribution on the thermal field distribution. The standardized model is constructed before the simulation, and the simulation effect is verified. This kind of building model is used to reproduce the essential process in the actual system. And through a series of experiments on the system model to study the existence or design of the system, also known as simulation. And the model discussed here, including physical or mathematical, static or dynamic. Continuous or discrete, and so on. In the simulation process, the magnetic field distribution can be visualized. At the same time, the thermal field distribution can be calculated and visualized according to the magnetic field intensity and load material, and different configuration parameters can be defined. It can calculate the magnetic field intensity of the coil disk model under different electrical parameters. It can also compare the effects of different configuration schemes (visual effect and contrast data). The self-defined parameter calculation model has corresponding test data and theoretical support document. In addition, the simulation model draws the file format which supports the general drawing tools CAD and Prop / E output. The simulation results can be output for the use of office files, and can output the dynamic change cloud image effect when the excitation source changes. At the same time, the corresponding program is designed by using the programming technology. Show the operating interface. By using ANSYSU Ansoft Maxwell and other simulation software. SolidWorks and other drawing software and Visual C programming software to achieve the purpose of these topics, can be a further exploration of the physical object. More comprehensive grasp of the details and internal functions, improve products, improve efficiency. Fully master the modeling software, simulation software proficiency in the application of physical simulation, so as to draw an effective conclusion. And it is applied to the production practice to provide the basis and theoretical basis for its realization.
