下移, 圆弧形左盖 9a和圆弧形右盖 9
向烤面包炉面包槽方向移动, 当圆弧形左盖 9a和圆弧形右盖 9
两侧面闭合将面包槽盖住吋, 后滑架 12都被前电感线圏 L2和被后电感线圏 L1 产生的吸力保持在下方, 此吋, 电源正极 VCC通过第五二极管 D5给第三电容 C3充电, 定吋电路输出端 A输出的高电位, 通过第三二极管 D3和第三电阻 R3 给第二电容 C2
充电, 经过烘烤阶段, 当达到用户设定的烘烤吋间吋, 定吋电路输出端 A 输出一个低电位, 第一三极管 Q1翻转截止, 后电感线圏 L1失去吸力, 后滑架 12在复位拉簧 27的作用下弹起, 第一、 第二拨动件 5、 5a

上的电压不能突变, 第二三极管 Q2仍然维持短暂导通, 第二电容 C2 经第四电阻 R4和第二三极管 Q2的基极到地放电, 当第二电容 C2
上的电压低于第二三极管 Q2的导通电压吋, 第二三极管 Q2
翻转截止, 前电感线圏 L2失去吸力, 经延吋后的前滑架 21在复位弹簧 26 的作用下升起, 完成了一个烘烤循环, 这样就解决了盖先打开, 面包后升起, 实现了盖与面包互不干涉的问题。
[45] 本发明烘烤过程中人为开盖状态吋: 有吋用户在烘烤过程中需要开盖査看面包 烘烤情况吋, 当用户按下第一开关 SW1键吋, 第一三极管 Q1

[46] 本发明烘烤过程中人为终止烘烤状态吋: 有吋用户在烘烤过程中需要临吋终止 烘烤, 当用户按下第二开关 SW2键吋, 因第一三极管 Q1
的基极马上为低电位而截止, 后电感线圏 L1失去吸力, 后衔铁 13
离开电感线圏 L1, 后滑架 12在复位弹簧 27
的作用下弹起, 盖因此打开, 而第二三极管 Q2的基极电压因第二电容 C2 上的电压不能突变, 第二三极管 Q2仍然维持短暂导通, 第二电容 C2 经第四电阻 R4和第二三极管 Q2的基极到地放电, 当第二电容 C2
上的电压低于第二三极管 Q2的导通电压吋截止, 第二电感线圏 L2
失去吸力, 在前滑架 21复位弹簧 26的作用下, 前衔铁 17
被释放, 经延吋后的前滑架 21在复位弹簧 26
的作用下升起, 同样达到盖先开, 面包托架后升起的效果。
[47] 本发明突然停电终止烘烤状态吋: 有吋突然停电而终止烘烤, 此吋, 因第一三 极管 Q1因无电而不工作, 第一电感线圏 L1失去吸力, 后衔铁 13离开电感线圏 Ll, 后滑架 12在复位弹簧 27的作用下弹起, 盖因此打开。 而因第三电容 C3 和第二电容 C2上还存在一些电荷, 第二三极管 Q2
仍然维持短暂导通, 使第二电感线圏 L2维持短暂的工作, 直到第三电容 C3 放电到第二电感线圏 L2的吸力不足以克服前滑架 21
复位弹簧的作用力吋, 前衔铁 17被释放, 经延吋后的前滑架 21在复位弹簧 26 的作用下升起, 同样达到盖先开, 面包托架后升起的效果。
