    摘要： This drop-down toaster has a bread support and a door at the bottom of each toasting compartment. The door has a series of vent holes for air convection which produces improved uniformity in the toast. The door and bread support are held closed by rollers on solenoid-controlled sliding bars. The rollers allow the door to swing open before the bread support is released, and they return the door and bread support to their normal condition automatically by a cam action. The bread support is cammed upwardly before release to dislodge bread from the toasting compartment guide wires. An electronic timing circuit is located in a base underneath and spaced vertically from the toasting section so that it is not affected by heat from the toasting section. The timing circuit is compensated in accordance with previous use rather than by sensing the temperature of the toasting compartment. That is, for any two successive toasting cycles, the second toasting cycle is made longer if the interval between the two cycles is longer and shorter if the interval between the two toasting cycles is shorter. Similarly, the second toasting cycle is dependent on the length of the preceding toasting cycle so that if the preceding toasting cycle is short, the second toasting cycle is long, and vice versa. The relay for switching current in the toaster heating elements is remote from the timer circuit board so that it can be replaced in the event of a short circuit without disturbing the circuit board.

    摘要翻译： 这个下拉式烤面包机在每个烘烤室的底部都有一个面包支架和一个门。 门具有一系列用于空气对流的通风孔，可以提高吐司的均匀性。 门和面包支架由电磁控制滑杆上的滚轮关闭。 滚筒允许门在打开面包支撑之前打开门，并且通过凸轮动作自动将门和面包支撑件返回正常状态。 在释放面包之前向上凸起面包，以便从烘烤室引导线上取出面包。 电子定时电路位于下方的基座中并与烘烤部分垂直隔开，使得其不受来自烘烤部分的热的影响。 定时电路根据先前的使用而不是通过感测烘烤室的温度来补偿。 也就是说，对于任何两个连续烘烤循环，如果两个烘烤循环之间的间隔较短，则如果两个循环之间的间隔更长和更短，则第二烘烤循环更长。 类似地，第二烘烤循环取决于前面的烘烤循环的长度，使得如果前面的烘烤循环较短，则第二烘烤循环较长，反之亦然。 用于在烤箱加热元件中切换电流的继电器远离定时器电路板，使得在短路的情况下可以更换，而不会干扰电路板。
