[0002]

2. Description of the Related Art As a conventional beer pouring device, the actual beer shovel 63
As shown in Japanese Patent Publication No. 190880, beer sent from a beer barrel passes through a coil-shaped cooling pipe arranged in cooling water in a cooling water tank, and a pouring cock directly attached to a tank wall of this cooling water tank. Some have been designed to be poured out in a timely manner.

Further, draft beer is usually passed through a cooling pipe in a cooling water tank for beer pouring, and a piping path is switched so that washing water can be flowed to the cooling pipe for cleaning when necessary, and maintainability is maintained. A beer dispenser with improved performance is also proposed.

FIG. 3 shows an external view of that type of beer dispenser, and FIG. 4 shows the internal structure of the dispenser. In each figure, 1 is a main body case, and its front panel 1
A pouring cock 2 for pouring beer is provided on the upper part of b.
A drain tray 3 is provided for receiving beer overflowing from a jug or the like at the time of extraction and drain water from the inside of the main body case 1.

Reference numeral 4 is a connection mouthpiece for detachably mounting a beer hose from a beer supply source (barrel) or a tap water hose for cleaning a pipe line arranged inside the main body case. As shown in FIG. 4, the inside of the main body case 1 is vertically divided by a unit top plate 6, and a compressor 8, a condenser 9, a condenser cooling fan 10 and a drive motor 11 for the fan 10 are provided in a lower room. A condensing unit consisting of etc. is stored.

On the other hand, in the upper room, a cooling water tank 13 is fixedly provided on the unit top plate 6. The cooling water tank 13 has a structure in which a water tank main body 7 made of stainless steel or the like is surrounded by a heat insulating material 14, and a sufficient amount of cooling water 15 is stored therein, and the cooling water 15 is cooled. Cooler 16 and a double-coil beer cooling pipe 17 disposed inside the cooler 16 for allowing beer from a beer source to pass therethrough and instantaneously cooling the beer.
Is provided.

The cooler 16 is connected to the condensing unit via a refrigerant pipe to form a refrigeration cycle. Further, the cooler 16 and the beer cooling pipe 17 are the support 1
It is attached and fixed to the No. 8 and installed in the cooling water tank 13.
Further, a stirring blade 19 is provided at the center of the inner bottom portion of the cooling water tank 13, and the stirring blade 19 is rotated by being commonly used by the driving motor 11 of the condenser cooling fan 10 to stir the cooling water and uniformly cool the cooling water. Is going.

By the way, the beer entered from the connection base 4 enters the beer cooling pipe 17 through a pipe line provided in the main body case 1 (not shown), and the beer in the cooled state discharged from the beer cooling pipe 17 is , The piping 21A and the piping 21B for communication which are sequentially arranged in the space 20 between the cooling water tank 13 and the front panel 1b provided with the pouring cock 2 are fed to the pouring cock 2 and pouring out. When the cock 2 is opened, beer is poured out from the beer outlet 2b.

A three-way valve 23 is inserted between the pipe 21A and the pipe 21B. The pipe 21B is connected to the common inlet of the three-way valve 23, the pipe 21A is connected to one of the two outlets, and the wash water pipe (not shown) is connected to the other outlet. Has become.

Normally, the three-way valve 23 is the pouring cock 2
The beer is poured out by switching to the side, but the operating portion 23b that projects this three-way valve 23 to the outside (see FIG. 3).
When the beer hose already connected to the connection mouth 4 is exchanged with the tap water hose, the tap water passes through the beer cooling pipe 17 and the three-way valve 23. After being discharged, the pipeline can be cleaned.

Now, the pipes 21A and 21B are arranged in the main body case 1 having an ambient temperature which is not much different from room temperature, and the beer cooled from the beer cooling pipe 17 passes therethrough.
There is a concern that the beer temperature will rise. When hot beer is poured out, it becomes frothy and loses its flavor.

Therefore, in order to prevent an increase in beer temperature,
Conventionally, the heat insulating material 25 has been wound around the pipes 21A and 21B, respectively. Further, in order to prevent the heat exhausted from the condensing unit from being transferred to the upper room, a sealing agent 26 is attached between the unit top plate 6 and the front panel 1b, and the pipes 21A, 21
The temperatures of B, the three-way valve 23, the beer pouring part, etc. are prevented from rising. Further, 29 is a foot, and 30 is a filter. And 31 is an upper lid.

[0013]

As described above, there is provided a beer dispenser having a washing function in which the pouring cock and the cooling water tank are separated from each other, and the beer pouring pipe and the cleaning pipe are laid in the separated space. In this case, since the pipe length from the beer cooling pipe 17 to the pouring cock 2 is long, the pipes 21A and 21B
And a considerable amount of beer stays in the three-way valve 23, and this staying beer is poured out every time when it is sold. In this case, if the beer pouring out is frequent, the beer temperature does not rise because the holding time is short, but there is no problem. In particular, when the beer dispensing interval becomes long (the so-called customer waiting state is long), the beer becomes hotter and is poured out.

In order to prevent this, conventionally, means for wrapping a heat insulating material around the beer pouring pipe or for providing a means for sealing the storage room of the condensing unit below is provided, and the beer discharged from the beer cooling pipe is poured into the cock. We took measures to prevent the temperature from rising during the period. However, there was a problem that the heat of the condenser could not be completely sealed, and as a result the temperature rose above room temperature, and the first beer had a lot of bubbles.

The present invention has been made in view of the above problems, and is constructed such that the pipes and parts from the beer cooling pipe to the pouring cock can be cooled using a cooling water tank,
Provided is a beer dispenser for suppressing foaming and constantly pouring out delicious beer.

The beer path is sufficiently cooled by arranging it in a heat insulating space provided between the case and the front surface. Therefore, compared to the conventional method of covering the beer path with the heat insulating material, the structure is simple and a sufficient cooling effect can be obtained. Therefore, there is no concern that the temperature of the beer staying in the beer route will rise, and regardless of the length of the pouring interval, it is possible to always pour out beer with less foaming.

In particular, since the heat insulating space is constituted by the heat insulating material and the wall surface of the cooling water tank so that the cooling water tank is effectively used as a cooling means, the cooling effect thereof is remarkably enhanced.
