    • A timer for controlling an appliance includes a housing. The timer also includes a camstack having a plurality of cam surfaces defined therein. The plurality of cam surfaces are positioned within the housing. The timer further includes a switch block which cooperates with the plurality of cam surfaces to provide switching operations for the appliance. Moreover, the timer includes an auxiliary member having a circuit pattern positioned on a side thereof. Rotation of the camstack causes rotation of the auxiliary member. The auxiliary member is positioned outside of the housing. The timer yet further includes a first switch arm positioned in contact with the side of the auxiliary member. Rotation of the auxiliary member causes the circuit pattern to be advanced into contact with the first switch arm. A method of controlling an appliance is also disclosed.
    • 用于控制器具的定时器包括壳体。 定时器还包括其中限定有多个凸轮表面的凸轮支架。 多个凸轮表面位于壳体内。 定时器还包括与多个凸轮表面协作以提供设备的切换操作的开关块。 此外,定时器包括具有位于其一侧的电路图案的辅助构件。 凸轮支架的旋转引起辅助构件的旋转。 辅助构件位于壳体的外部。 定时器还包括定位成与辅助构件的侧面接触的第一开关臂。 辅助部件的旋转使得电路图案进入与第一开关臂接触。 还公开了一种控制器具的方法。

    • An escapement mechanism for an appliance timer includes a cylindrically shaped driving member which is concentric with the axis of the appliance timer program wheel. One or more cam lobes providing camming surfaces are formed on an interior cylindrical wall of the driving member. A ratchet wheel is disposed for rotation within the driving member. The ratchet wheel is drivingly connected to the program wheel. A pawl having a ratchet wheel engaging tooth at one end and a cam follower at the other end is actuated by the camming surfaces on the driving member to cause the pawl to move a predetermined distance in a first direction, engage the ratchet wheel, and then return the same distance in the opposite direction to advance the ratchet wheel and the program wheel in response to rotation of the driving member.
    • 用于器具定时器的擒纵机构包括与器具定时器程序轮的轴线同心的圆柱形的驱动构件。 在驱动构件的内圆柱形壁上形成提供凸轮表面的一个或多个凸轮凸角。 棘轮设置成在驱动构件内旋转。 棘轮驱动地连接到程序轮。 在一端具有棘轮啮合齿和另一端的凸轮从动件的棘爪由驱动构件上的凸轮表面驱动,以使棘爪沿第一方向移动预定距离,接合棘轮,然后 在相反的方向返回相同的距离,以响应于驱动构件的旋转来推进棘轮和程序轮。
