Beverage dispenser

A beverage dispenser comprising a multivalve that mixes syrup selectively discharged from a plurality of syrup nozzles and dilution water discharged from a dilution water supply section and that supplies the mixture, wherein

• the beverage dispenser further comprises a cleaning adapter configured to form a cleaning space in which each syrup nozzle and the dilution water supply section are located between the cleaning adapter and the multivalve and to clean each syrup nozzle by the dilution water discharged from the dilution water supply section,
• the cleaning space between the cleaning adapter and the multivalve is sealed above a nozzle distal end portion of each syrup nozzle and the dilution water supply section,
• the cleaning adapter includes a discharge port that discharges the dilution water after cleaning each syrup nozzle from a position higher than the nozzle distal end portion of each syrup nozzle,
• the multivalve includes:
• a diffuser in which each syrup nozzle and the dilution water supply section are formed;
• and a spout detachably attached to outside of the diffuser via an O-ring and configured to guide the dilution water from the dilution water supply section so as to collide with the syrup from the syrup nozzle, and
• in a state where the spout is removed, the cleaning adapter is detachably mounted on a mounting portion for detachably mounting the spout, and a gap between the cleaning adapter and the diffuser is sealed by the O-ring above the nozzle distal end portion of each syrup nozzle and the dilution water supply section.
