Description

[Detailed description of the invention] The present invention relates to a beverage cooling dispensing machine that cools beverages by submerging the evaporation pipe of the refrigeration mechanism and the beverage cooling pipe in a liquid tank storing a cooling liquid such as water. This invention relates to a beverage cooling and dispensing machine that prevents the beverage in the beverage cooling tube from freezing due to ice generated around the evaporation tube.

In such a beverage cooling dispensing machine, a problem that must be avoided is that the beverage cooling pipe is covered with ice formed in the evaporation pipe and the beverage inside is supercooled and frozen. For this reason, conventionally, the evaporation pipe is placed at the top and the beverage cooling pipe at the bottom, or vice versa, and when the beverage cooling pipe is screwed into the liquid tank in a coiled manner, the inlet to the liquid tank and The outlet piping was arranged so that it did not come into contact with the evaporation tube and ice.
This poses a major constraint on the structure of the pouring machine, resulting in a loss of flexibility and the disadvantage of making the pouring machine larger than necessary. Another proposed configuration is to arrange the beverage cooling pipe and evaporation pipe in a concentric coil, with the beverage cooling pipe on the outside and the evaporation pipe on the inside, but in this case, sufficient ice storage cannot be achieved. It had drawbacks.

The purpose of the present invention is to eliminate such drawbacks, and the purpose is to prevent the beverage from freezing in the beverage cooling pipe, and to create a compact and highly efficient beverage cooling dispensing machine that stores enough ice without having to use a large structure. It is about providing.

The present invention will be explained below with reference to FIGS. 1 and 2 showing one embodiment. A cooling liquid 3 such as water is stored in a liquid tank 2 covered with a heat insulating material 1, and an evaporation pipe 5 connected to a refrigeration mechanism 4 is arranged in a coil shape outside the cooling liquid 3. Inside, a beverage cooling tube 6 for passing the beverage is arranged in a coiled manner, and both tubes 5 and 6 are arranged concentrically and vertically. The base end of the beverage cooling pipe 6 is connected to a beverage supply source (not shown) via a pot 7, and the tip thereof is connected to a pouring pot 8.

In addition, since a blade 10 fixed to the rotating shaft of an electric motor 9 is installed in the center of the beverage cooling pipe 6,
The cooling liquid 3 circulates inside the liquid tank 2 by flowing from the top to the bottom inside the beverage cooling pipe 6 and from the bottom to the top outside the beverage cooling pipe 6. The coolant 3 cooled by the evaporator tube 5 in this manner effectively cools the beverage in the beverage cooling tube 6.

A shaded line 11 on the outer periphery of the evaporation tube 5 is generated ice, and an ice storage control element 12 controls the refrigeration mechanism 4 to store a certain amount of ice. The beverage that flows through the beverage cooling pipe 6 and is poured out via the pouring pot 8 exchanges heat with the cooling liquid 3, and as a result, the stored ice 11 gradually melts due to the heated cooling liquid 3. Therefore, the amount of beverage cooling is affected by the amount of stored ice 11. Here, the first step is to increase the amount of water stored in ice 11.
As shown in the figure, it is desirable to install the evaporation pipe 5 on the wall side of the liquid tank 2 and the beverage cooling pipe 6 inside thereof. Since such a beverage cooling pouring machine is generally installed on a table top such as a counter, the overall height is limited by itself, and the evaporation pipe 5 is provided close to the bottom of the liquid tank 2. For this reason, the beverage cooling pipe 6 is installed so as to penetrate between the coil pitches of the evaporation pipe 5, and it penetrates the ice 11, causing the above-mentioned freezing of the beverage.

The present invention prevents the beverage from freezing inside the beverage cooling pipe 6, and its details will be explained with reference to FIG.
A hollow cylinder 16 having heat insulating properties is liquid-tightly fixed to the wall surface of the liquid tank 2 on which the pouring pot 8 is placed. Into the inner hole of the hollow cylinder 16 is inserted a mounting shaft 18 that is connected to the beverage cooling pipe 6 and has a flow path 17 . The mounting shaft 18 has a spout 8 removably attached to its left end via a mounting nut 23, and its right end is fixed to the hollow cylinder 16 by a nut 19 and connected to the beverage cooling pipe 6 by a union nut 20. Further, a sealing member 21 such as an O-ring is provided near the right end of the mounting shaft 18, so that the coolant 3 is prevented from entering between the mounting shaft 18 and the hollow cylinder 16. Also, the distance between the pitches of the evaporation tube 5 is
As shown in the figure, a mounting shaft 18 connected to the beverage cooling pipe 6 passes through the outer periphery of the mounting shaft 18 covered with a hollow cylinder 16. In order to prevent ice from forming in this penetrating portion, a heat insulating material 25 is provided around the outer periphery of the evaporator tube 5 corresponding to the upper and lower portions of the mounting shaft 18.

In the above example, the explanation was given on the outlet side of the beverage cooling pipe 6, that is, the side connected to the pouring pot 8, but this configuration is naturally applicable to the inlet side of the beverage cooling pipe 6, that is, the side connected to the pouring pot 7. In this case, one side of the mounting shaft 18 is connected to a conduit leading to the outside of the liquid tank 2 and having a pot 7, and the other side is connected to a beverage cooling pipe 6. A heat insulating material 25 is provided on the evaporator tube 5 at the upper and lower portions of the mounting shaft 18.

FIG. 3 shows another embodiment of the present invention. In this example, in order to further improve the heat insulation of the evaporator tube 5, a liquid seal is provided between the heat insulating material 26 and the evaporator tube 5 from the coolant 3. An air layer 27 is provided.

Next, the operation of the pouring machine according to the present invention will be explained. When the cooling mechanism 4 is operated, ice is gradually generated around the evaporation pipe 5, but in the pouring machine of the present invention, ice is formed around the evaporation pipe 5 in the vicinity where the mounting shaft 18 connected to the beverage cooling pipe passes through the evaporation pipe 5. Since the outer circumference of the evaporator tube 5 is covered with a heat insulating material 25 or 26, the evaporator tube 5
No ice forms around the periphery. Furthermore, since the outer periphery of the mounting shaft 18 is covered with the hollow shaft 16 having heat insulation properties, the beverage inside the mounting shaft 18 will not freeze.

As mentioned above, the beverage cooling dispensing machine according to the present invention has a mounting shaft placed inside a hollow tube with heat insulation at the part that exits the beverage cooling pipe, and a pot is attached to one end of the mounting shaft, and a cup is attached to the other end. The cooling pipes were connected, and the evaporation pipes above and below the mounting shaft passing through the evaporation pipes were covered with a heat insulating material. Therefore, since there is no ice at all in the portion of the beverage cooling pipe that passes through the evaporation tube, the beverage in the beverage cooling pipe no longer freezes. Furthermore, the evaporator tubes were constructed to be long, and ice was formed only in a very small portion, so a large amount of ice could be stored and efficient cooling became possible.
