Beverage characterized in that a lower part of a supply conduit for supplying beverage to a beverage cooling pipe is accommodated in a heat insulating space formed therebetween, and an inlet of the supply conduit is connected to a connecting member attached to the lower front portion of the apparatus main body Supply equipment It is intended to provide.

  If it does in this way, the heat insulation space by a heat insulation separator will be formed in the front of a refrigerating device so that the cooling air of a condenser may not remain in a device main part, and a drink will be supplied to a drink supply pipe in this heat insulation space Since the lower part of the supply conduit is accommodated, the beverage in the supply conduit is not affected by the temperature of the freezer.

  Further, in the beverage supply device configured as described above, the heat insulating separator may be composed of a plurality of spaced plate materials and an air layer formed between them, and even in this case, the heat insulating space The beverage in the supply conduit accommodated in the container is not affected by the temperature of the refrigeration apparatus. Furthermore, since the heat-insulating separator has a heat-insulating air layer, it is not necessary to provide a heat-insulating material on the plate material.

Moreover, in a beverage supply device constructed as described above, the at least one heat insulation space and the air layer is provided outside air inlet in communication with the outside, cooling the pre-SL component a is the condenser of the refrigeration apparatus The fan may be sucked in outside air taken in from the outside air intake port and passing through at least one of the heat insulating space and the air layer. In this way, at least one of the heat insulating space and the air layer is sucked. The outside air flows and heat is not trapped, and the beverage in the supply conduit accommodated in the heat insulating space is not affected by the temperature of the refrigeration apparatus.

  As shown in FIG. 5 and FIG. 6, a heat insulating separator 40 </ b> A is provided on the front side of the refrigeration apparatus 20 at the front lower portion of the apparatus main body 10, and heat insulation is provided between the heat insulating separator 40 </ b> A and the front wall of the apparatus main body 10. A space S is formed. The heat insulating separator 40A is composed of two sheet metal partition plates 41A, a partition plate 42A, and a heat insulating air layer 43A formed between the partition plates 41A and 42A.

  The partition plate 41 </ b> A is attached to the lower part on the front side of the apparatus main body 10 by a flange 41 </ b> A <b> 1 provided at the lower part, and divides the space formed between the front wall of the apparatus main body 10 as the heat insulating space S. The partition plate 42A is attached between the partition plate 41A and the refrigeration apparatus 20 by being separated from the partition plate 41A by the left and right brackets 42A1 and 42A2. In the space between the partition plate 42A and the partition plate 41A, A heat insulating air layer 43A is formed. Since the partition plate 42A is attached by left and right brackets 42A1 and 42A2 provided between the partition plate 41A and the partition plate 42A, the width of the left and right brackets 42A1 and 42A2 is set between the partition plate 41A and the partition plate 42A.

  Further, since the supply conduit 35 is accommodated in the heat insulating space S and the heat insulating material 32 of the cooling water tank 31 and is not affected by the temperature of the refrigeration apparatus 20, the beverage stays in the supply conduit 35. When it is done, the flavor of the beverage is not impaired, and propagation of germs can be suppressed. Further, when a beverage containing carbon dioxide gas is included, the beverage in the supply conduit 35 is not warmed, so that it is possible to suppress the generation of unnecessary bubbles at the time of dispensing.

  The heat-insulating separator 40A forming the heat-insulating space S is heat-insulated by the heat-insulating air layer 43A, so that it is not necessary to stick a heat-insulating material or the like to the partition plates 41A and 42A, and the efficiency of the assembly work is improved.

  The air layer 43A is provided with an air intake port 45A, and the air taken in from the air intake port 45A flows to the condenser 22 through the air layer 43A. Thereby, even if the partition plate 42A is warmed by the refrigeration apparatus 20 and the air in the air layer 43A is warmed, air is always taken into the air layer 43A from the outside of the apparatus body 10, and the air layer 43A is heated. The heat insulating property of the heat insulating separator 40A increases.

  The heat insulation space S is provided with an air intake 45A, and the air taken in from the air intake 45A flows through the heat insulation space S to the condenser 22. Thereby, even if the heat-insulating separator 40A is warmed, heat is not accumulated in the heat-insulating space S, and the beverage in the supply conduit 35 accommodated in the heat-insulating space S is not affected by the temperature of the refrigeration apparatus 20. become.
