A water cooler, fountain or bottle filler solenoid valve is actuated by an infrared light beam sensor. When light beam is interrupted by subject in front of cooler desiring a drink, the sensor actuates the solenoid valve which then opens to allow water flow. No physical contact with cooler is required. A built in time delay is provided to prevent actuation by persons moving past cooler. There is a maximum running time of 30 seconds to prevent malicious damage to the cooler or water damage if sensor vision is blocked. Unit automatically resets when blockage is removed. Sensor range is adjustable.
A solenoid valve is an electrically controlled water valve found in many water coolers, bottle fillers and drinking fountains. When a user presses the push bar, an electrical signal is sent to this valve which opens and lets water flow for as long as the push bar remains in the pressed position. Once the push bar is released the valve closes and prevents water from continuing to flow through.
