PROBLEM TO BE SOLVED: To provide a drink dispenser capable of suppressing temperature fluctuations of a carbonated drink and preventing a large amount of bubbles from being formed. SOLUTION: The number of rotations of a motor for operating a compressor 49 constituting a refrigerating apparatus is controlled by an inverter 51. An in-case temperature sensor 52 is connected to a control base board 50 for an in-case temperature, and the control base board 50 is connected to the inverter 51 through a communicating means. In the case where the in-case temperature sensor 52 detects a temperature higher than a preset level, the inverter 51 makes larger a frequency and a voltage to be supplied to the motor and increases the number of rotations of the motor to increase a refrigerating capacity of the compressor 49, and on the contrary, the in-case temperature sensor 52 detects a temperature lower than the preset level, the inverter 51 makes smaller the frequency and the voltage to be supplied to the motor and reduces the number of rotations of the motor to decrease the refrigerating capacity of the compressor 49. By this method, fluctuations of an in-case temperature in a storage chamber and of a temperature of beer remaining in a supply pipe and a hose for supplying the drink are suppressed to a slight level, and the frothing of beer in pouring it is controlled.
