The invention provides an auxiliary liquid supplying system for an ice cube machine and the ice cube machine, and relates to the technical field of ice making related equipment. The auxiliary liquid supplying system for the ice cube machine comprises a fluoride pump, a first pipeline, a second pipeline, an auxiliary liquid reservoir and a gas-liquid separation device, wherein the first pipeline and the second pipeline are respectively connected with the ice cuber machine; the first pipeline is used for conveying refrigerant to the ice cuber machine; the second pipeline is used for conveying the refrigerant passing through the ice cuber machine to the gas-liquid separation device; liquid separated by the gas-liquid separation device is conveyed into the auxiliary liquid reservoir through athird pipeline; and the auxiliary liquid reservoir is connected with the fluorine pump through a fourth pipeline. The auxiliary liquid supplying system for the ice cuber machine can convey the refrigerant to an evaporator of the ice cuber machine by utilizing the fluorine pump, so that more refrigerant is arranged in the evaporator of the ice cuber machine; the heat exchange efficiency of the evaporator is improved; the ice making efficiency of the ice cuber machine is improved; and energy is saved.
