  • Patent number: 6422180
    Abstract: A flush line for dishwasher mainly includes a steam boiler provided at an upstream position of the flush line and having a water inlet connected to a water-in valve and a water outlet connected to a water stop valve; and a pump and a spray nozzle sequentially located downstream the water stop valve. When the water-in valve is opened, running water enters into the flush line to pass the steam boiler, at where the water is heated to produce a specific volume of steam that passes the pump and is pressurized before being sprayed via the nozzle to flush dishes in the dishwasher. High-temperature steam instantaneously evaporates 1i residual fat on the dishes and disinfects the same. Since steam contains less moisture, dishes washed with steam need not be dried with an electric heater.
