The cooling water inside is cooled through a copper evaporation pipe 17. On the other hand, the winding pitch P1 of the winding portion along the inner wall surface on the front side of the evaporation tube 17 is wound so as to be smaller than the winding pitch P2 of the winding portion along the inner wall surface on the rear side. It is attached so that the lowermost step is substantially horizontal. Furthermore, a heat insulating material 26 is wound at a predetermined thickness over the entire width of the front inner wall surface at the uppermost portion of the evaporation pipe 17 wound along the front inner wall surface. Further, inside the evaporation pipe 17 in the water tank 15, a beverage cooling pipe 20A is attached on a concentric axis so that the beverage cooling pipe 20B is radially outward and the beverage cooling pipe 20B is radially inner. And the extraction side end part of each drink cooling pipe 20A, 20B is each extraction cock 8, 8 attached so that it may adjoin to the upper end part of the uppermost heat insulating material 26 of the evaporation pipe 17 of the front side in the water tank 15.

[0021]
Therefore, the height from the bottom surface of the uppermost step along the inner wall surface on the front side of the evaporation pipe 17 is lower than the height from the bottom surface of the uppermost stage along the inner wall surface on the rear side. The height of the ice 35 formed around the portion adjacent to the dispensing end portions 8A, 8A on the uppermost stage is the height of the ice 35 formed around the other part on the uppermost stage of the evaporation pipe 17. Lower than this. Thereby, even if the height of the dispensing side end of each beverage cooling pipe 20A, 20B is formed lower than before, the dispensing side end of each beverage cooling pipe 20A, 20B and the ice 35 can be easily contacted. The beverage cooling pipes 20A and 20B can be formed with a lower height in the vertical direction, and the height of the water tank 15 can be reduced. can do. On the other hand, since the height of the ice 35 formed in other portions other than the portion adjacent to the uppermost extraction end portions 8A, 8A of the evaporation pipe 17 can be made the same as the conventional one, The amount of ice can be made substantially the same, and the cooling capacity can be increased while being small.
Moreover, since the upward growth of the ice 35 is obstructed around the portion of the evaporation pipe 17 where the uppermost heat insulating material 26 is provided, the end portions of the beverage supply pipes 20A and 20B are insulated. Even if it is close to the material 26, contact with the ice 35 can be easily avoided, the height of each of the beverage cooling pipes 20A, 20B can be made lower, and the height of the water tank 15 can be further increased. Can be lowered.
