摘要： A hand dryer timer having a switch in electrical communication with, and controlling the operation of a heater, a fan motor and a timer motor which are electrically connected to two nonneutral lines of a power source. A cam is mounted on a drive shaft of the timer motor such that the cam rotates with the drive shaft and also slides longitudinally over the drive shaft. The cam has a cam lobe adjacent an actuating arm of the switch. A biasing element is located between the timer motor and the cam and biases the cam to a first position aligning the cam lobe with the actuating arm of the switch. The switch includes two sets of switch contacts in a power circuit for the heater and fan motor, so that at the end of a drying cycle, the two sets of switch contacts are effective to electrically isolate the heater and fan motor from both non-neutral lines of the power source.

摘要： A hand dryer timer assembly including a plate with a timer motor mounted on one side of the plate and a switch mounted on an opposite side of the plate. The switch is in electrical communication with, and controls the operation of, the timer motor. A cam is mounted on a drive shaft of the timer motor such that the cam rotates with the drive shaft and also slides longitudinally over the drive shaft. The cam extends through an opening in the plate and has a flange at one end located adjacent the one side of the plate to prevent the one end of the cam from moving past the one side of the plate. The cam further has a cam lobe located on the opposite side of the plate adjacent an actuating arm of the switch. A biasing element is located between the timer motor and the cam and biases the cam to a first position aligning the cam lobe with the actuating arm of the switch.
摘要翻译：一种干手器定时器组件，其包括安装在板的一侧上的定时马达的板和安装在板的相对侧上的开关。开关与定时电机电气通信并控制定时电机的运行。凸轮安装在定时电机的驱动轴上，使得凸轮与驱动轴一起旋转并且还在驱动轴上纵向滑动。凸轮延伸穿过板中的开口，并且在位于板的一侧附近的一端具有凸缘，以防止凸轮的一端移动经过板的一侧。凸轮还具有位于板的与开关的致动臂相邻的相对侧上的凸轮凸角。偏置元件位于定时电机和凸轮之间，并将凸轮偏压到将凸轮凸角与开关的致动臂对准的第一位置。
