具体实施方式
以下结合实施例对本发明作进一步的描述。
如图1、图2、图3所示，一种快速烘烤多士炉，包括机芯组件1、滑架组件2、驱动组件5和固定在底座上的外壳7，所述机芯组件1由前侧板105、侧板101、后侧板102固定连接成机芯的烘烤槽后，固定在底座106上，所述发热管组件4固定在前侧板105、后侧板102上，位于前侧板105、后侧板102之间，所述滑架组件2包括滑架201、滑架201上固定的托架202，所述滑架201上还固定有隔网框组件3，所述托架202位于隔网框组件3之中，所述滑架
201位于机芯组件1的前侧板105的外侧，所述托架202和隔网框组件3位于机芯组件1面包烘烤槽内，所述隔网框组件3的网框内设有隔网301和夹紧弹簧，所述隔网301与所述隔网框组件3形成活动连接，所述前侧板105的内侧面上部固定有引导隔网301打开的“倒八”字角钢307，所述滑架组件2由驱动组件5驱动，驱动滑架201沿着立轴107上下移动。
所述发热管组件4包括发热管支架401和发热管402，发热管402通过发热管支架401分别固定在前侧板105和后侧板102上，位于前侧板105和后侧板102之间，位于滑架201上固定的托架202、隔网框组件3的两边。本实施例采用发热快、发热效率高的石英发热管，一般使用二支以上，也可以采用不锈钢发热管或其他发热管。
所述隔网框组件3由前夹板304、侧夹板302、后夹板303固定连接成框，所述隔网框组件3通过上下连接板305与滑架201固定连接，隔网301位于网框内，与其形成活动连接。所述隔网一般由若干条竖钢丝和两根以上的横钢丝焊接成网状格网，成为隔网，用于烘烤面包时夹持面包，使面包置于面包烘烤槽的中心，隔网还有使面包与多士炉发热元件隔离的作用，使面包与发热元件
有一个适当的距离，这样才能使面包烘烤得更均匀。
所述前夹板304和后夹板303的上部分别开有隔网301的导向槽3012，隔网上横条3011的两端分别位于导向槽3012中，所述前夹板304和后夹板303的下部分别开有隔网孔3014，隔网下横条3013的两端分别位于隔网孔3014中。
所述侧夹板302的下部中心还设有隔网定位片308，定位片308上开有定位孔3081，隔网301中心的竖钢丝插入定位孔3081中，使隔网301被定位而不会前后移动。
所述前夹板304的上翻边上设有两个孔，“倒U”形夹紧弹簧306的两条腿穿过该孔，固定在前夹板304的上翻边上， “倒U”形夹紧弹簧306向下伸出的两条腿分别抵住隔网上横条3011外侧。“倒U”形夹紧弹簧306向下伸的两条腿压住隔网上横条3011外侧，使隔网301始终具有向托架202方向即面包烘烤中心靠的力，为此，当面包6被放入面包烘烤槽中时，能够使面包6置于面包烘烤槽的中心，而使面包6被烘烤时，面包6的两面颜色一样均匀。
所述隔网上横条3011伸出所述前夹板304的一端位置上与所述“倒八”字角钢307的立边外侧竖直方向对应。当滑架201向上移动时，左右隔网上横条3011刚好靠在“倒八”字角钢307的立边外侧，随着滑架201的继续上升，带动滑架201上固定的隔网301和隔网框3上升，隔网301被“倒八”字角钢307逐渐撑开，从而达到使隔网完全打开，用户能够方便地取出烘烤好的面包的目的。
所述机芯组件1的前端固定有支架104，支架104与底座106之间固定有立轴107，所述滑架201与立轴107形成滑动连接，所述滑架201的前端面上设有导槽204。
所述驱动组件5包括电机支座502，电机支座502上固定的下限位开关506、上限位开关504和电机501，所述电机501输出轴上固定有摇臂503，摇臂503上铰接有滚轮505，滚轮505位于滑架201前端面上设置的导槽204中，与其形成滑动连接，电机支座502固定在底座106上。
如图1、图2、图3所示，在多士炉的未工作状态时，滑架201和固定在滑架201上的托架202在机芯组件1的最高位置。因此时隔网框组件3也处于机芯组件1的最高位置，隔网301已经被“倒八”字角钢307完全撑开，隔网301为撑开状态，以便于放置和取出面包。在这种情况下，若需要烘烤面包时，将面包片放入多士炉的两个隔网内，面包会在重力的作用下自动处于两个隔网301的中心。按要求设置好烘烤面包颜色的档位，按下“开始”按钮，石英发热管组件4通电发热，电机501也同时启动，由于电机501输出轴上固定的摇臂503上铰接的滚轮505处于滑架201前端面上的导槽204中，且滑架201处于机芯的最高位置。当电机501开始旋转时，在本实施例中，电机501是顺时针旋转的，电机501的旋转带动摇臂503转动，摇臂503上的滚轮505在滑架201上的导槽204上滚动，由于电机201向顺时针方向旋转，所以滚轮505将压迫滑架201上的导槽204的下凸边，迫使滑架201向下移动，从而带动滑架201上固定的托架202和隔网框组件3向下移动。如图4所示，这时，隔网框组件3内的隔网301的隔网上横条3011逐渐离开“倒八”字角钢307，在夹紧弹簧306弹力的作用力的作用下，隔网301开始逐渐合拢，此时，面包6被隔网301逐渐置中，滑架201上固定的托架202托着面包继续向下移动。当滑架201下降一段距离后，隔网301在夹紧弹簧306的弹性力的作用下，完全夹紧面包6，如图5、图6所示；当滑架201下移到机芯组件1的最低位置时，如图7、图8所示，摇臂503已经旋转了将近180度，摇臂503上铰接的滚轮505处于导槽204内，且位于机芯的最低位置，滑架201已经下移到机芯的最低位置。此时，摇臂503上的凸起碰触到下限位开关506，控制电路检测到下限位开关506闭合，即滑架201已经到达机芯组件1的底部，控制电路控制电机501停止转动，根据程序设置，控制电路控制电机501反转，即控制电机501逆时针旋转，电机501的旋转带动摇臂503转动，摇臂503上的滚轮505在滑架201上的导槽204上滚动，由于电机201向逆时针方向旋转，所以滚轮505将压迫滑架201上的导槽204的上凸边，迫使滑架201向上移动，从而带动滑架201上固定的托架202和隔网框组件3向上移动。这时，滑架201在电机501的驱动下开始上移，滑架201上固定的托架202和隔网框组件3带着面包6也一起向上移动。
控制电路对电机501旋转的时间进行计时，控制电机501的旋转时间，当电机501旋转的时间达到设定的时间时，滑架201、滑架201上固定的托架202、隔网框组件3和隔网框组件3内的面包6已经上升了一定距离，如图5、图6所示，这时，控制电路控制电机501反向旋转，滑架201在电机501的驱动下开始下移，滑架201、滑架201上固定的托架202、隔网框组件3和隔网框组件3内的面包6开始向下移动，控制电路对电机501旋转的时间进行计时，控制电机501的旋转时间，当电机501旋转的时间达到设定的时间时，滑架201、滑架201上固定的托架202、隔网框组件3和隔网框组件3内的面包6已经下移了一定距离，这样就完成了一个烘烤循环。通过实验，可以确定几个上下移动的烘烤循环为某一个挡位，对不同的面包烘烤颜色等级设定不同数量的烘烤时间和上下移动的烘烤循环，就可以形成多个不同的面包烘烤颜色档位。当多士
炉烘烤达到用户设定的烘烤档位时间后，烘烤循环结束。控制电路控制电机使滑架201上升的方向旋转，从而滑架201在电机501的驱动下开始上移，滑架201上固定的托架202和隔网框组件3带着面包6也一起向上移动。当滑架201上固定的托架202和隔网框组件3带着面包6上升到一定位置后，隔网301的隔网上横条3011开始接触到前侧板105内侧面上部固定的“倒八”字角钢307，“倒八”字角钢307将隔网301缓慢撑开，当摇臂503旋转到达最高位置，触碰到上限位开关209后停止，此时，滑架201、滑架201上固定的托架202和隔网框组件3带着面包6上移到达了最高位置，烘烤好的面包片也上升到机芯的顶部，“倒八”字角钢307已经将隔网301完全撑开，用户可以很方便的取出烤好了的面包。
一种快速烘烤多士炉的控制方法：
A、在控制电路中设置档位选择钮，档位按电机旋转的顺时针和逆时针旋转次数为一个循环设定或一个完成时间，每个档位按不同的若干个循环区分；
B、控制电路检测到“开始”信号后，初始化，控制电路检测档位控制信号，判断多士炉设定的烘烤档位；
C、控制电路控制发热管通电加热，多士炉进入烘烤面包工作状态；
D、控制电路控制电机往顺时针方向旋转；
E、当控制电路检测到下限位开关闭合信号后，控制电机停止旋转，暂停半秒；
F、控制电路控制电机往逆时针方向旋转，控制电路开始计时，当电机旋转到设定的时间后，暂停半秒；
G、控制电路控制电机往顺时针方向旋转；
H、控制电路判断是否达到设定档位的电机旋转的循环次数或完成时间；
I、若电机旋转的循环次数小于设定档位循环次数或未达完成时间，则返回步骤F；若电机旋转的循环次数等于设定档位循环次数或到达完成时间，则控制电路控制电机往逆时针方向旋转；直到上限位开关闭合，控制电路控制发热管停止加热，电机停止旋转，结束烘烤循环；
L、若控制电路检测到“停止”信号，则控制电路控制电机往逆时针方向旋转；直到上限位开关闭合，控制电路控制发热管停止加热，电机停止旋转，结束烘烤循环。
这里所述的电机旋转方向可以根据需要设置，当驱动滑架向上移动时电机是顺时针旋转，驱动滑架向下移动时电机是逆时针旋转；也可以是驱动滑架向上移动时电机是逆时针旋转，驱动滑架向下移动时电机是顺时针旋转；只需要调整上限位开关和下限位开关的位置位于电机输出轴上的摇臂的左侧还是右侧就可以实现。当上限位开关和下限位开关的位置位于电机输出轴上的摇臂的左侧时，驱动滑架向上移动时电机是逆时针旋转，驱动滑架向下移动时电机是顺时针旋转；而当上限位开关和下限位开关的位置位于电机输出轴上的摇臂的右侧时，驱动滑架向上移动时电机是顺时针旋转，驱动滑架向下移动时电机是逆时针旋转。
当需要烘烤面包时：
(1)、接通电源，设置“烘烤档位”；
(2)、将面包放入多士炉的面包烘烤槽中，按下“开始”键，控制电路控制石英发热管开始加热，电机正向旋转，多士炉进入烘烤面包工作状态；
(3)、根据程序设置，当电机摇臂旋转到底部，触碰到下限位开关后，暂停半秒，然后，控制电路控制电机反向旋转，反向旋转到设定的时间后，再暂停半秒，然后，控制电路又控制电机以相反的反向旋转，这样，滑架、滑架上固定的托架和隔网框托着面包，在已经发热的面包烘烤槽中反复上下移动，如此反复，直到完成设置“烘烤档位”的工作时间。
(4)、当达到设置的“烘烤档位”的工作时间时，控制电路控制石英发热管停止发热，这时，不管滑架处在什么位置，控制电路都会控制电机暂停半秒，然后，再控制电机反向旋转，直到触碰顶部的上限位开关，随后进入待机状态，一个面包烘烤循环结束，用户可以取出面包了。
(5)、或中途按“停止”键结束工作。
本发明可以提高功率，增大发热量，能够快速烘烤面包，并且能够解决面包烘烤不均匀的问题，在面包片烘烤过程中，将面包片在一定距离内移动，使面包片受热均匀。这样即能快速烘烤，又能使面包片烘烤均匀。
