所述面板2的通孔与温控器3之间或设置有排水结构或设置有避免汤汁进入内腔的密封结构。
所述密封结构避免烹饪锅体底部和面板2上端的汤汁通过通孔、温控器3之间的间隙进入到电磁炉内部。
所述密封结构为密封圈，所述密封圈设置在通孔中。
所述密封圈内壁处形成环形凸筋，所述环形凸筋的内径与温控器3外壁为过盈配合。环形凸筋能够有效的减少温控器3外壁过盈配合的接触面积，减小对温控器3伸缩行程的阻力影响。
如图15所示，所述密封结构包括设置在通孔处的装配套9，所述装配套9上端设置有密封垫91，所述密封垫91上端与烹饪锅体相接触，所述密封垫91下端与温控器3的感温盖32相接触。
所述密封结构为封堵通孔并与温控器3的感温盖32弹性贴合的密封垫91，所述密封 垫91下端形成咬合通孔的装配套9。
所述底壳中设置有压块，所述压块将装配套9下端压紧在面板2的下端面上。
所述压块为中空柱状压块，所述压块的下端与支撑架相固定。
所述密封垫91材质为密封硅胶，密封垫91由于其弹性变形能够有效的对烹饪锅体进行贴合包覆。
密封垫91自身有一定的弹性延展性能，自由状态下温控器3在驱动弹簧作用下将密封垫91顶起一定高度。放上烹饪锅体后，温控器3在烹饪锅体及其盛装的食材重力作用下驱动弹簧变形将整个温控器3缩回基本与面板2平齐。同时，在驱动弹簧的弹力作用下，温控器3的感温盖32会紧紧的贴合在烹饪锅体底部，使得温控器3的感温盖32能很好的感应烹饪锅体底部温度。

如图17所示，所述温控器3除了上述伸缩的固定方式外还可以采用固定结构将温控器的感温盖32稍探出面板2的上端，所述温控器3上端的感温盖32探出面板2上端高度为0～5mm。
所述感温盖32能够与面板2上的烹饪锅体直接接触，感温盖32能够直接感应烹饪锅体的温度，从而能够真实感应锅内食材的实际温度。
所述感温盖32与面板2的距离为h，所述0≤h≤5mm，该h高度既能够保证感温盖32与锅底的直接接触，又能够减少烹饪锅体与面板2的间隙，广泛适用于各类锅体，便于使用者烹调操作。
当感温盖32与面板2之间的间距h小于0时，面板2对烹饪锅体进行支撑，而感温盖 32与烹饪锅体非接触，会直接影响温控器3的感温。
当感温盖32与面板2之间的间距h大于5mm时，烹饪锅体底部要做比较高的凸包避空传感器，对烹饪翻炒动作影响很大。
所述温控器3与通孔配合孔隙位置填充环氧树脂、502胶、快干胶或RTV硅胶之类的材料，并通过填充物自然表干或烘干使温控器3固定在面板预设位置。
所述感温盖32的外壁处还可以形成外螺纹，面板2下端套在外螺纹上的螺母，从而将温控器3进行固定。
如图18所示，所述温控器3侧壁处设置有限制温控器3探出高度的探出限位装置，所述探出限位装置包括凸出限位筋61，所述温控器3侧壁处还设置有温控器3伸缩过程中导向的对中限位筋62。
所述凸出限位筋61、对中限位筋62均为多个，所述凸出限位筋61上端与面板2相抵，从而能够限制温控器3探出面板2的高度。
所述对中限位筋62、凸出限位筋61纵向对齐。
所述对中限位筋62、凸出限位筋61纵向交错。
所述对中限位筋62包括上方的倾斜部621和下方的平直部622。
所述倾斜部621自上而下高度逐渐增加，所述平直部622的高度与倾斜部621的最大高度相一致。
所述对中限位筋62能够使温控器3沿着面板2的通孔滑动探出，在探出的过程中，对中限位筋62能够保证温控器3探出后与通孔同轴，保证探出的精度，而其对中限位筋62还能够在滑动探出的过程中，起到减速的作用，对中限位筋62能够避免温控器1探出后的周向晃动，增加装配的紧凑型。
所述凸出限位筋61上端为与面板2接触的平面，其下端为圆弧状。
所述对中限位筋62、凸出限位筋61均沿环向均布。
所述温控器3凸出面板2的高度为H，所述高度H满足以下条件，0.5mm≤H≤6mm。
所述对中限位筋62与通孔的内壁配合，防止温控器3歪到一边，保证温控器3与面板2周圈间隙均匀；所述对中限位筋62的高度为0.1～0.5mm。
本发明中面板处形成通孔，通孔中设置有伸缩式的温控器，从而能够实现温控器与烹饪锅体底部的贴合，保证温控器对烹饪锅体底部的温度进行精确测量，通过温控器感温盖的优化，减少传导过程中热量的损耗，通过面板下端的绝缘层、导水孔、挡水筋实现面板碎裂后绝缘防水防护，通过面板通孔处的密封结构或排水结构避免面板上的汤汁进入到底壳的电 气元件中，本发明实现了电磁炉的精确控温，提高了使用安全性。
