一种烘烤器开关机构 技术领域
本发明是一种烘烤器开关机构，特别是一种面包烘烤器开关机构,属于烘烤器开关机构的改造技术。

本实施例中，上述滑动组件1包括有挂钩13、开关启动器14、推条座16、面包托17、开关杆19，其中挂钩13通过挂钩转轴131铰装在推条座16上，且挂钩13上端部设置有挂钩弹簧12，推条座16至少一侧设置有能活动的开关启动器14，开关启动器14根部设置有开关启动器弹簧15，开关杆19设置于推条座16上，且正对铆接于开关组件2上第一动触片261或第二动触片262的上方。
本实施例中，上述滑动组件1通过导轴31套接于炉胆3，且正对开关组件2的上方；滑动组件1与炉胆3或炉底4之间还装设有滑动组件弹簧11，滑动组件弹簧11的一端着力于滑动组件1，另一端着力于炉胆3或炉底4。本实施例中，上述开关组件2固定于炉底4。
本实施例中，上述开关组件2包括有开关压杆21、电磁铁23、开关支架24，开关压杆21通过压杆转轴215套接于开关支架24上，电磁铁23固定于开关支架24上；开关压杆21设置有能自由活动的磁吸片22，磁吸片22与电磁铁23相邻设置。
此外，上述开关组件2中的开关支架24一侧或两侧铆接有三块静触片251、252、253，三块静触片251、252、253另一端铆接有三个静触点30、31、32；第一动触片261、第二动触片262的一端铆接于开关支架24，另一端正对于静触片251、252、253悬空设置；第一动触片261、第二动触片262中间开缝成“U”字型，第一动触片261包括有第一动触片的第一弹片2611及第一动触片的第二弹片2612，第一动触片的第一弹片2611铆接有动触点27，第一动触片的第二弹片2612铆接有动触点28，第二动触片262包括有第二动触片的第一弹片2621及第二动触片的第二弹片2622，第二动触片的第一弹片2611铆接有动触点29，且所述动触点27、28、29与所述静触点30、31、32相邻对应设置。
另外，上述开关组件2中设置有能自由活动的磁吸片22的开关压杆21能绕压杆转轴215摆动，一端铆接于开关支架24的第一动触片261、第二动触片262位于开关压杆21的摆动区间；开关压杆工作面216与第一动触片的第一弹片2611、第二动触片的第一弹片2621、第二动触片的第二弹片2622相互作用，实现第一动触片261、第二动触片262的压紧、弹开。
本实施例中，上述滑动组件1的开关启动器14还设有锲形工作面141、开关启动器导向面142；开关杆19设有能着力于第一动触片261及第二动触片262的工作面191。
本实施例中，上述滑动组件1的开关启动器弹簧15一端设置于开关启动器14的根部，另一端挂靠于开关启动器14的中部，正对在弹丝151中间区域位置推条座16设置有弹簧限位扣161，限制开关启动器14旋开的角度及二次弹开支点。
另外，上述开关组件2的开关压杆21还设有压杆卡扣孔211、压制面212、退刀槽213、开关杆工作导向面214、退刀斜面217、压杆斜面218，其中开关启动器导向面142受开关杆工作导向面214导向能作用至开关杆压制面212，锲形工作面141作力于开关杆压制面212能迫使开关压杆21绕压杆转轴215向电磁铁23方向摆动；挂钩13前端能触及压杆斜面218且受其阻力作用使挂钩13绕挂钩转轴131摆动，挂钩扣132滑至压杆卡扣孔211时，挂钩13能在挂钩弹簧12的弹力作用下绕挂钩转轴131向相向方向摆动卡入压杆卡扣孔211使锲形工作面141脱离压制面（212，启动器退刀面143能碰及退刀斜面217迫使开关启动器14向外旋动，启动器退刀面143脱离退刀斜面217时使开关启动器14离开退刀槽213。
本发明的工作原理如下：
如图1及图6～图8所示滑动组件1在滑动组件弹簧11作用下处于自由释放，悬挂于开关组件2上方，此时开关压杆21受到第一动触片的第一弹片2611、第二动触片的第一弹片2621的弹力作用向外侧倾斜，即开关压杆工作面216被第一动触片的第一弹片2611、第二动触片的第一弹片2621撑开，铆接于第一动触片的第一弹片2611、第二动触片的第一弹片2621、第一动触片的第二弹片2612上的动触点27、28、29与铆接于静触片251、（252、253上的静触点30、31、32间隙均达到3mm电安全距离，开关断电，且磁吸片22脱离电磁铁吸附面231。开关启动器14受开关启动器弹簧15扭力作用及限位扣161所限制旋开角度悬挂于压迫面212上方。
受外力作用滑动组件1向下移动，开关启动器导向面142受开关杆工作导向面214导向作用至开关杆压制面212，锲形工作面141作力于开关杆压制面212迫使开关压杆21绕压杆转轴215向电磁铁23方向摆动；开关压杆工作面216压制第一动触片的第一弹片2611、第二动触片的第一弹片2621、第二动触片的第二弹片2622，迫使第一动触片的第一弹片2611、第二动触片的第一弹片2621摆动，附于其上动触点27、28向静触点30、31接近，此过程开关杆工作面191压制第一动触片的第二弹片2612，迫使第一动触片的第二弹片2612摆动，附于其上动触点29向静触点32接近。滑动组件1继续向下移动，开关压杆21绕压杆转轴215向电磁铁23方向进一少摆动，最终所有动、静触点接触，电路导通。电磁铁23通电产生磁力，活动设置于开关压杆21上的磁吸片22被牢牢吸附在电磁铁吸附面231；同时，在此过程，挂钩13前端触及压杆斜面218且受其阻力作用使挂钩13绕挂钩转轴131摆动，如图7所示。当挂钩扣132滑至压杆卡扣孔211时，挂钩13在挂钩弹簧12弹力绕挂钩转轴131向相向方向摆动，卡入压杆卡扣孔211，如图8，滑动组件1被钩住，磁吸片22仍吸附于电磁铁吸附面231。此时多士炉达到稳定工作状态，满足吸力性能要求。此时开关启动器14不再需要给开关压杆21施加压制，锲形工作面141脱离压制面212，开关启动器14受开关启动器弹簧15扭力作用及限位扣161所限制旋开角度回程到退刀槽213。
多士炉工作结束或按动电子停止键或拔电，电磁铁23断电失去磁力，开关压杆工作面216受到第一动触片的第一弹片2611、第二动触片的第一弹片2621弹力、第二动触片的第二弹片2622，开关压杆21绕压杆转轴215向外摆动；同时开关杆19脱离第一动触片的第二弹片2612，三对动、静触点脱离，开关断电；挂钩扣132脱离压杆卡扣孔211，在滑动组件弹簧11弹力作用下滑动组件迅速向上跳动。在此跳动过程，启动器退刀面143碰及退刀斜面217迫使开关启动器14向外旋动，已被限位弹丝151绕限位扣161向外张开，滑动组件1向上继续跳动，启动器退刀面143脱离退刀斜面217，开关启动器14离开退刀槽213，开关启动器14受被限位扣161所限制旋开角度开关启动器弹簧15扭力作用回程，重新悬挂于压迫面212上方，实现弹簧二次弹开。
上述滑动组件1向上移动过程中，若开关长期工作，第一动触片的第一弹片2611、第二动触片的第一弹片2621的弹力均有弹力变弱机会，额外增加第二动触片的第二弹片2622作用于开关压杆工作面216，附加一层保障弹力确保开关压杆21绕压杆转轴215向外摆动，触点有效脱离，达到可靠安全断电！
多士炉稳定工作时，实现开关持续通电。模拟卡死面包托17或和提手18，按动电子停止键，电磁铁23断电失去磁力，开关压杆21被第一动触片的第一弹片2611、第二动触片的第一弹片2621弹开，附于其上的动触点27、28脱离附于静触片251、252上的静触点30、31，由于有外力限制，面包托无法跳起，但动、静触点间隙完全可以达到3mm安全距离，实现安全断电，满足开关全极断开要求。符合即将实施IEC60335-2-9最新版按住外露提手断电安规要求。
