[0001] The utility model relates to the technical field of draft beer machines, in particular to a beer column of an air-cooled draft beer machine and a cold air circulation device inside the beer column. Background Art

[0002] The draft beer machine places the barreled beer in a refrigerated box with a beer column, then connects the barreled beer and the beer outlet on the beer column with a pipe, and then configures a separate carbon dioxide gas tank. When the beer is discharged, the carbon dioxide gas tank flushes carbon dioxide into the draft beer barrel, and through the gas pressure, the beer in the barrel is squeezed out, and finally flows out from the beer outlet for people to drink.

[0003] Existing draft beer machines are equipped with refrigeration equipment, but the beer column has no refrigeration function. When the beer machine is not used for a period of time, the beer in the beer column will gradually heat up from the refrigerated state to the room temperature state. When the beer is dispensed, the room temperature beer in the beer pipe inside the beer column comes out first. When the room temperature beer passes through the beer head, it collides with the inside and easily releases a large amount of carbon dioxide to form foam. Therefore, most of the beer that comes out at the beginning is foam.

[0004] To solve the above problems, existing draft beer machines are equipped with an additional water cooler, and the water pipes of the water cooler and the beer pipes are bundled together inside the beer column. Since the water in the water cooler is constantly circulating, the beer pipes in the beer column can be cooled. However, this solution requires an additional water cooler for circulating refrigeration, which has high costs and energy consumption. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Please refer to the attached Figure 1 , Attachment Figure 2 The utility model discloses a beer column of an air-cooled draft beer machine and a cold air circulation device inside the beer column, comprising a beer column 2, a draft beer machine housing 1, a carbon dioxide tank 11, and barreled beer 12 in the draft beer machine housing 1. The carbon dioxide tank 11 and the barreled beer 12 are connected by a pipeline, and the beer is pumped out by pumping carbon dioxide into the barreled beer 12. A refrigeration device for refrigeration air is also installed in the draft beer machine housing 1. A beer head 22 is installed on the outer wall of the beer column 2, and a beer outlet pipe 21 connecting the beer head 22 and the barreled beer 12 is installed in the beer column 2. The utility model also includes a cold air circulation system 3, wherein:

[0031] The beer column 2 is hollow inside and can be detachably mounted on the upper end of the draft beer machine housing 1;

[0032] The cold air circulation system 3 includes an air induced draft fan 26 fixed in the beer column 2, an air inlet sleeve 31 and an air outlet structure for exhaust. The air inlet sleeve 31 and the air outlet sleeve 32 are both fixed at the bottom of the beer column 2 for connecting the beer column 2 and the draft beer machine chassis 1. The air induced draft fan 26 is fixed in the beer column 2 or in the air outlet structure or in the air inlet sleeve 31;

[0033] The air induced fan 26 faces upward and is fixed to the top of the beer column 2. The air outlet structure includes an air outlet, which is used to connect the beer column 2 with the draft beer machine chassis 1. The air inlet sleeve 31 extends to the bottom of the beer column 2.

[0034] A plurality of fisheye marks 24 are installed on the top of the wine column cover 23, and each fisheye mark 24 is installed at an angle position aligned longitudinally with the wine head 22. An insulation layer 25 covering the inner wall of the wine column 2 is installed in the wine column 2. Specifically, the insulation layer 25 can insulate the cold air in the wine column 2.

[0035] In this embodiment, the air intake fan 26 introduces the cold air in the draft beer machine housing 1 into the beer column 2, and the cold air is then discharged from the air outlet on one side, thereby realizing the cold air circulation inside the beer column 2.

[0036] Example 2: Please refer to the attached Figure 3 Based on the further improvement of the above-mentioned embodiment 1, the difference between embodiment 2 and embodiment 1 is that it further includes another induced air fan 26, and the air outlet structure includes an air outlet sleeve 32, which is fixed at the bottom of the wine column 2 for connecting the wine column 2 and the draft beer machine chassis 1. The air outlet sleeve 32 and the air inlet sleeve 31 are the same length and are arranged in parallel. The upper ends of the air outlet sleeve 32 and the air inlet sleeve 31 extend to the bottom of the wine column 2, and the other induced air fan 26 faces downward and is fixed in the air outlet sleeve 32.

[0037] In this embodiment, the air intake fan 26 in the beer column 2 cooperates with the air inlet sleeve 31 to introduce the cold air in the draft beer machine case 1 into the beer column 2, and the air outlet sleeve 32 cooperates with the air intake fan 26 inside it to discharge the cold air in the beer column 2, thereby realizing the cold air circulation inside the beer column 2 and avoiding the confusion of the intake and exhaust flow directions after the internal cold air enters the beer column 2, resulting in poor overall cooling effect inside the beer column 2.

[0038] Example 3: Please refer to the attached Figure 4 , Attachment Figure 5 Based on the further improvement of the above-mentioned embodiment 2, the difference between embodiment 3 and embodiment 2 is that the length and position of the air outlet sleeve 32 are different, and another air induced fan 26 is included. The air outlet structure includes an air outlet sleeve 32, and the air outlet sleeve 32 is fixed at the bottom of the wine column 2 for connecting the wine column 2 and the draft beer machine case 1. The air outlet sleeve 32 is arranged parallel to the air inlet sleeve 31. The upper end of the air inlet sleeve 31 extends to the bottom of the wine column 2, and the upper end of the air outlet sleeve 32 extends to the upper half of the wine column 2 and is not higher than the position of the wine head 22. The other air induced fan 26 faces downward and is fixed in the air outlet sleeve 32.

[0039] In this embodiment, this design allows the cold air to cool the wine outlet pipe 21 from the bottom to the top, and then discharge this part of the cold air from the air outlet sleeve 32. On the basis of the cold air circulation, the cold air is maximized and it is avoided that the cold air is discharged by the air outlet sleeve 32 and the air intake fan 26 inside it as soon as it enters the wine column 2, thereby causing poor cooling effect on the upper half of the wine column 2.

[0040] Example 4: Please refer to the attached Figure 6 , Attachment Figure 7 Based on the further improvement of the above-mentioned embodiment 1, the difference of embodiment 4 compared with embodiment 3 is that the air outlet structure includes an air outlet, which is used to connect the beer column 2 and the draft beer machine chassis 1, and the upper end of the air inlet sleeve 31 extends to the upper half of the beer column 2 close to the top wall of the beer column 2 and not higher than the beer head 22, and the air exhaust fan 26 is fixed in the air inlet sleeve 31 and the wind direction is upward.

[0041] In this embodiment, the design allows the cold air to cool the wine outlet pipe 21 from bottom to top, and then discharge this part of the cold air from the air outlet on both sides, eliminating the air intake fan 26 inside the wine column 2, so that the length of the wine column 2 can be shortened, reducing material costs.

[0042] Example 5: Please refer to the attached Figure 1 , Attachment Figure 8, based on the further improvement of the above embodiments, the top of the wine column 2 is detachably mounted with a wine column cover 23, the bottom of the wine column cover 23 and the top of the wine column 2 are both mounted with flanges, the wine column cover 23 is connected to the wine column 2 through a flange, the bottom of the wine column 2 is mounted with a flange, the wine column 2 is connected to the draft beer machine chassis 1 through a flange, a plurality of wine heads 22 are mounted and are evenly distributed on the outer wall of the wine column 2 with the central axis of the wine column 2 as the center of the circle, and the wine column 2 is a single vertical cylinder;

[0043] In this embodiment, the detachably mounted beer column 2 can be used to add additional beer columns 2 according to the size of the draft beer machine. Multiple beer columns 2 and beer heads 22 can be used by multiple people to use the draft beer machine at the same time, and there is a detachable beer column cover 23 on the top of the beer column 2 to facilitate maintenance of the air intake fan 26.

[0044] By circulating the cold air from the cold storage cabinet and the air in the wine column in any way, the purpose of keeping the wine column stable at a temperature close to that of the wine storage cabinet for a long time is achieved.

[0045] The working principle and usage process of the present invention are as follows: when the draft beer machine is in use, the draft beer machine housing 1 is filled with cold air and is in a cooling state, and the upward-facing air induced fan 26 in the beer column 2 continuously draws the cold air in the draft beer machine housing 1 into the beer column 2, and the air induced fan 26 in the beer column 2 drives the cold air from the air inlet sleeve 31 into the beer column 2. After the cold air enters the beer column 2, it moves upward under the guidance of the air induced fan 26. During this process, the cold air refrigerates the beer in the beer outlet pipe 21 in the beer column 2. When the cold air flows to the top of the beer column 2, under the action of another air induced fan 26, the cold air is sucked into the air outlet sleeve 32 and then discharged into the draft beer machine housing 1. As the cold air continuously enters and is discharged from the beer column 2, the beer outlet pipe 21 is circulated and cooled, so that the temperature of the beer in the draft beer machine and the beer in the beer column 2 is kept consistent.
