## Abstract

A beverage dispenser is disclosed that includes a cleaning adapter configured to form a cleaning space in which each syrup nozzle and a dilution water supply section are located between the cleaning adapter and a multivalve and to clean each syrup nozzle by dilution water discharged from the dilution water supply section. A gap 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 discharge port 71 that discharges the dilution water after cleaning each syrup nozzle from a position higher than the nozzle distal end portion of each syrup nozzle.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The beverage dispenser according to claim 1, wherein the cleaning adapter has a shape that follows the syrup nozzles.

### Claim 3 (depends on 1)

The beverage dispenser according to claim 1, wherein the cleaning adapter includes a cylindrical portion whose upper and lower ends are opened and whose top end constitutes the discharge port, while each syrup nozzle is located so as to surround the outside of the cylindrical portion, and the dilution water discharged from the dilution water supply section is discharged from above each syrup nozzle onto an inner peripheral surface of the cleaning adapter.

### Claim 4 (depends on 1)

The beverage dispenser according to claim 1, wherein
carbonated water is discharged from the dilution water supply section, and
the beverage dispenser includes a function of ejecting carbon dioxide for generating the carbonated water from the dilution water supply section.
