Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a beverage cooling device that cools a beverage through a cooling liquid using a cooler provided in a tank.

Beverage cooling devices are already known in which a partition tube is fitted into the tank body, a cooler is provided inside the partition tube, and a flexible pipe is provided between the partition tube and the tank body to allow the beverage to pass through. Since the purpose of a cooling device is to cool the beverage that passes through a corrugated pipe, it cannot cool the beverage in a beverage container such as a bottle or barrel. Therefore, in such a case, a separate cooling device must be installed. This has the disadvantage that the installation area and equipment costs are large.

The present invention has been completed with the aim of providing a beverage cooling device that does not have the above-mentioned drawbacks, and the illustrated embodiment will be described in detail below.

Reference numeral 1 denotes a tank body of a cooling device filled with a cooling liquid such as water, and the tank body 1 and a lid body 2 that closes the upper end thereof are formed on a wall body of a heat-insulating structure. 1, a first inner tank 5 having a center opening 3 in the bottom plate 4 is fitted with a cooling liquid flow path 6 formed between the tank body 1 and the first inner tank 5. A coolant flow path 6 between each side wall of the inner tank 5 is provided with a cooler 7 which is formed in a spiral tube shape and serves as a refrigerant evaporator.One end of the cooler 7 is connected to the tank via a conduit 8. The other end of the cooler 7 is connected to a compressor 9 installed at the bottom of the body 1, and the other end of the cooler 7 is equipped with a cooling fan 12 located on the side of the compressor 9 via a conduit 11 having an expansion valve 10 in the middle. is connected to the condenser 13 of the compressor 9 and the condenser 13.
and are connected by a conduit 14.

15 is fitted concentrically into the first inner tank 5 and
A second inner tank forms a coolant flow path 16 between the second inner tank 15 and the second inner tank 15. It is approximately the same as or slightly below the upper end opening surface of the inner tank 5,
Further, the bottom plate part 17 of the second inner tank 15 is provided with a center opening 18 corresponding to the center opening 3 of the bottom plate part 4 of the first inner tank 5. A serpentine pipe 19 through which the beverage to be cooled passes is provided in the coolant flow passage 16 between the side walls and the respective side walls.
1 and the lower end is connected to cock 2 for taking out beverages.
It is connected to a conduit 23 with 2.

Further, a vertical motor 24 is mounted on the outside of the center of the bottom of the tank body 1 so as to face upward.
There is an impeller 26 for water conveyance used in centrifugal pumps and other devices.
That is, an impeller 26 is fitted that discharges the water sucked in from the central suction port radially around the four circumferences, and the impeller 26 is located between the bottom of the tank body 1 and the bottom plate part 4 of the first inner tank 5. The suction port 27 faces the center opening 3 of the first inner tank 5, and the rotation of the impeller 26 driven by the motor 24 The coolant A in the coolant flow passage 16 between the first inner tank 5 and the second inner tank 15 is sucked into the suction port 27 at the same time.
The coolant A in the coolant 5 is also sucked into the suction port 27 through the central opening 18 of the bottom plate portion 17, and the two coolants A are combined and discharged radially toward the coolant flow passage 6.

Note that 28 is a holding stand for the opening of the drink in the container, and is installed in the second inner tank 15.

With this structure, the lid 2 can be opened, or a door (not shown) provided on the lid 2 as needed can be opened to insert a beverage opening containing a container filled with the desired beverage into the tank 1. and place it on the support stand 28 of the second inner tank 15, and in this state adjust the amount of cooling liquid so that the water level of the cooling liquid A in the tank body 1 is slightly above the upper end opening surface of the first inner tank 5. After that, when the compressor 9 is operated and the motor 24 is driven to rotate the impeller 26, the suction action of the impeller 26 causes the coolant I in the coolant flow passage 16 to flow into the first inner tank 5. and the outer wall surface of the second inner tank 15 and flow at high speed toward the center opening 3 of the first inner tank 5. During this time, the beverage in the corrugated pipe 19 is cooled and the beverage flows into the suction port 27 of the impeller 26. At the same time,
The cooling liquid A in the second inner tank 15 is guided by the inner wall surface of the second inner tank 15 and the outer surface of the container at the container opening, and flows at high speed toward the center opening 18 of the second inner tank 15. The beverage opening in the container is cooled and passes through the central opening 18 to the suction opening 2 of the impeller 26.
The heat-exchanged coolant A that has been sucked into the tank 7 and merged in this way becomes a high-speed radial flow from the impeller 26 and flows through the bottom of the tank body 1 and the bottom plate part 4 of the first inner tank 5. The coolant is discharged toward the bottom side of the side wall of the tank body 1 through the coolant flow passage 6 between the tank body 1 and the coolant flow passage 6 which is then guided to the inner surface of the side wall of the tank body 1 and the outer surface of the side wall of the first inner tank 5. During this time, the cooler 7
The cooling liquid A is cooled by the cooling liquid A, and then passes through the upper end openings of the first inner tank 5 and the second inner tank 15 to the impeller 26.
The coolant flows into the second inner tank 15 and the coolant flow path 16 between the first inner tank 5 and the second inner tank 15 where the suction action of Since the cooling liquid A cooled by the cooler 7 is constantly flowing evenly and in contact with each other at a high speed around the container beverage opening, the beverage inside each is effectively cooled.
Both the beverage discharged from the cock 22 and the beverage in the beverage mouth of the container are appropriately cooled.

However, the impeller 26 is concentric with the first inner tank 5 and the second inner tank 5.
By being located at the lower side of the inner tank 15, the single impeller 26 enables forced circulation of the beverage in the serpentine pipe 19 and the cooling liquid for cooling the bottled beverage spout, which is extremely convenient. Since the coolant radially discharged by the wheels 26 does not leak out from the boundary between the tank body 1 and the lid body 2, maintenance in this respect is extremely simple.

As is clear from the above explanation, according to the present invention,
The cooling liquid inside the tank can cool the containerized beverages in addition to the beverages passing through the serpentine pipe, so in addition to the continuous supply of chilled beverages, it is also possible to supply a large amount of chilled beverages at once using containerized beverages. Not only can it be used for a variety of purposes, but it also has many advantages, such as the ability to forcefully circulate the coolant using a single impeller, and it is a small device with a simple structure that can be manufactured at low cost. The value is extremely great.
