Abstract: A beverage making machine may be arranged to cool a precursor liquid in a tank using a cooling liquid in a cooling container disposed around the tank. The cooling liquid may be freezable to form ice, e.g., to provide the system with improved cooling capacity and/or speed. A plurality of fins may extend between the tank and the cooling container, with each of the plurality of fins being physically attached to the cooling container or the tank and being arranged to conduct heat from the tank and/or from the cooling liquid. The plurality of fins may include first portions attached to the tank and extending outwardly, and second portions attached to the cooling container and extending inwardly. Side surfaces of corresponding first and second portions may be in contact with each other to aid in transferring heat via the fin portions.

Abstract: A beverage making machine may employ a mixing chamber to mix a beverage medium with a precursor liquid, such as carbonated water. The mixing chamber may have a precursor liquid inlet coupled to a precursor liquid supply, a beverage medium chamber to receive a beverage medium into the beverage medium chamber, and a dispense outlet from which beverage medium and precursor liquid are dispensed, e.g., into a user's cup. The beverage medium chamber may include a chamber inlet coupled to the precursor liquid inlet, e.g., so precursor liquid can enter the chamber when a pressure is low in the beverage medium chamber, and a chamber outlet downstream of the chamber inlet that is coupled to the dispense outlet, e.g., so that beverage medium can exit the chamber.
