A beverage maker platen overflow sensing system is disclosed. The sensing system includes a process control board (PCB) in communication with solenoid valves of a manifold, the solenoid valves controlling the flow of hot water (e.g., for brewing coffee or tea) into a server positioned in a platen of the beverage maker. The PCB further includes an overflow detection circuit connected to the solenoid valves. Two signal probes are positioned near the forward edge of the platen. Similarly, ground probes are positioned in the platen below the signal probes and providing a ground path to the PCB. The overflow detection circuit generates an electrical signal between the signal probes and detects an overflow state when fluid in the platen grounds the signal between the signal probes and the groundprobes. While the overflow persists, the overflow detection circuit ceases the water flow by electrically signaling the solenoid valves to close.
公开了一种饮料制造机台板溢流感测系统。感测系统包括与歧管的电磁阀通信的处理控制板(PCB),该电磁阀控制热水(例如,用于冲泡咖啡或茶)流入定位在饮料制造机的台板中的服务器。PCB还包括连接到电磁阀的溢流检测电路。两个信号探针定位在台板的前边缘附近。类似地,接地探针在台板中定位在信号探针下方并且提供到PCB的接地路径。溢流检测电路在信号探针之间生成电信号,并且在台板中的流体使信号探针和接地探针之间的信号接地时检测到溢流状态。在溢流持续存在时,溢流检测电路通过以电子方式发信号通知电磁阀关闭来停止水流。
