Description

Technical Field

[0001] The utility model relates to the technical field of draft beer machines, in particular to a cold air circulation device used for cooling the interior of a beer column in a draft beer machine. 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] Because the existing beer columns mainly include vertical beer columns and U-shaped beer columns, the U-shaped beer columns can be installed with more beer heads and can serve more people than the vertical beer columns, but relatively speaking, the supply path of the U-shaped beer columns is longer, and the beer in the beer outlet pipe of the U-shaped beer column is affected by the temperature more than the vertical beer column. In order to solve the above problems, the existing draft beer machine will add an additional water cooler, and bundle the water pipe of the water cooler and the beer pipe together in the beer column. Since the water of the water cooler is constantly circulating for cooling, this solution requires an additional water cooler for circulating refrigeration, which has high cost and energy consumption. When used for a draft beer machine with a larger U-shaped beer column, the length of the water pipe used also increases, increasing the equipment cost. Utility Model Content

[0005] The utility model provides a cold air circulation device for cooling the inside of a beer column in a draft beer machine, which has the advantage of refrigerating the beer in the beer column at a low cost, thereby solving the problems of high cost and energy consumption of additional water cooling in existing draft beer machines.

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.

[0023] Please see the attached Figures 1-4 The utility model discloses a cold air circulation device for cooling the inside of a draft beer machine column, comprising a beer column 2, a draft beer machine chassis 1, and barreled beer 11 in the draft beer machine chassis 1. The outer wall of the beer column 2 is mounted with a plurality of beer heads 22, and a beer outlet pipe 21 is mounted inside the beer column 2 to connect the beer heads 22 and the barreled beer 11. The utility model is characterized in that it also includes a cold air circulation component 3, wherein:

[0024] The beer column 2 is hollow inside and can be detachably mounted on the upper end of the draft beer machine case 1; Example 1:

[0025] The cold air circulation assembly 3 includes an air inlet assembly 31 for introducing cold air into the wine column and an air outlet assembly 32 for discharging cold air from the wine column;

[0026] The air inlet kit 31 and the air outlet kit 32 respectively include an air inlet tube 311 and an air outlet tube 321 . A fan 33 with an upward wind direction is installed in the air inlet tube 311 , and a fan 33 with a downward wind direction is installed in the air outlet tube 321 .

[0027] Specifically, the wine column 2 is an inverted U-shaped pipe structure, which is assembled from a cylindrical pipe and a right-angle pipe head through a flange. It is a conventional structure of the wine column 2 and will not be described in detail here. The wine column 2 is symmetrically provided with connecting ports 23 at both ends. The air inlet 311 and the air outlet 321 are respectively fixed at the connecting ports 23 to connect the wine column 2 and the draft beer chassis 1. The channel in the air inlet 311 is smaller than the channel in the air outlet 321 and is eccentrically arranged. The size of the fan 33 in the air inlet 311 is also smaller than the fan 33 in the air outlet 321. The implementation of this patent is not limited to Figure 4A preferred arrangement, as long as it achieves the above-mentioned effects, is an implementable technical solution of this patent, for example: the air inlet channel is large and the air outlet channel is small, or the air inlet channel can be small and the air outlet channel large, or the air inlet and outlet channels can be the same size. The wine outlet pipe 21 passes through the air inlet cylinder 311 and enters the wine column 2. The fan 33 in the air inlet cylinder 311 is located at the side end of the wine outlet pipe 21. Example 2:

[0028] The cold air circulation component 3 is provided with an air inlet kit 31 for introducing cold air into the beer column. The air inlet kit 31 allows the cold air in the beer column 2 to circulate and refrigerate the beer in the beer outlet pipe 21 in the beer column 2, so that the temperature of the beer in the draft beer machine and the beer in the beer column 2 is consistent and no foam is generated. Example 3:

[0029] The cold air circulation component 3 is provided with an air outlet kit 32 for conducting cold air out of the beer column. The air outlet kit 32 allows the cold air in the beer column 2 to circulate and refrigerate the beer in the beer outlet pipe 21 in the beer column 2, so that the temperature of the draft beer machine and the beer in the beer column 2 are kept consistent and no foam is generated.

[0030] It should be noted that the air inlet kit 31 and the air outlet kit 32 can be used alone or in combination, and can be set at any feasible position in the wine column 2 according to actual needs.

[0031] More specifically, an insulation layer 24 is installed on the inner wall of the wine column 2 to prevent the temperature inside the wine column 2 from being affected by the external environment. The cross-section of the wine column 2 is circular, and the diameter of the wine column 2 can be preferably set to about 80 mm, which is larger than the size of a conventional wine column 2. It can increase the fluidity of the cold air and improve the effect of the cold air circulation. Whether the wine column is round or square, or has a diameter of 81 mm or 85 mm, etc., it is determined according to actual production and application.

[0032] The working principle and usage process of the present invention are as follows: the refrigeration equipment in the draft beer machine case 1 generates cold air, and the draft beer machine case 1 is filled with cold air and is in a cooling state. The fan 33 in the air inlet tube 311 draws the cold air in the draft beer machine case 1 upward into the beer column 2. The cold air enters the beer column 2 from the connecting port 23 on one side and flows along the beer column 2 to the connecting port 23 on the other side. In this process, the cold air refrigerates the beer in the beer outlet pipe 21 in the beer column 2. At the same time, the fan 33 in the air outlet tube 321 at the connecting port 23 on the other side discharges the cold air downward, so that the cold air in the beer column 2 circulates to refrigerate the beer in the beer outlet pipe 21 in the beer column 2, so that the temperature of the beer in the draft beer machine and the beer column 2 is consistent, and no foam is generated.
