  • Patent number: 11360112
    Abstract: A cleaning water flow velocity during nozzle cleaning is momentarily changed by using a pressure changing mechanism, for example, a syringe. That is, after the start of cleaning, a solenoid valve is opened, and an aspirating operation of the syringe is momentarily performed by a fixed amount in a state where a flow of cleaning water in a nozzle is developed, whereby a nozzle flow velocity is momentarily decelerated. Immediately thereafter, the syringe is pushed back to a home position again, and the flow velocity in the nozzle is accelerated again. A cleaning effect can be improved by performing transition of velocity distribution to various states. Flow velocity control by the pressure changing mechanism can be realized without inhibiting a dispensing cycle, and the cleaning effect of the nozzle can be improved without changing the pressure of a liquid feeding pump or extending the cleaning time.
