Circuit for washing a water-feeding system in automatic beverage vending machines

摘要

A novel washing circuit for use in an automatic beverage vending machine is disclosed. The circuit comprises a switching cock enabling communication between the upstream side of a water-feeding pump and one end of a return conduit. The other end of the return conduit is adapted to be detachably connected to the water supply nozzle of the vending machine. When the switching cock is opened and the return conduit is connected to the nozzle, the water-feeding pump of the machine can pump washing solution through the water-feeding system of the machine and facilitate cleaning thereof.
