FIELD: beverage dispensing devices.
SUBSTANCE: ultrasonic cleaning device comprises a liquid reservoir, a piezoelectric transducer and a generator. The generator is configured to generate a high frequency electronic signal and transmit it to the piezoelectric transducer so that the piezoelectric transducer receives the signal and responds by changing the waveform during the entire time the electronic signal is applied. The ultrasonic cleaning device comprises a housing which is configured to be detachably connected to the dispensing group.
EFFECT: improved cleaning efficiency with the possibility of removal of mineral deposits without dismantling the equipment and manual cleaning, time input is reduced, and quality of coffee is improved.
