Description
Technical Field
[0001] The utility model relates to the technical field of beverage equipment, in particular to a heat exchange refrigeration pipe positioning structure for a beer machine. Background Art
[0002] The main function of a beer dispenser is to cool beer to a suitable drinking temperature through a specific cooling method and then use pressure to push the beer out of the keg for consumption. Depending on the cooling method, beer dispensers can be categorized into various types, including vertical coil-cooled, direct keg-cooled, and direct bottle-cooled. Vertical coil-cooled beer dispensers are the most common type on the market. A beer dispenser's refrigeration system typically consists of a refrigeration unit, a chiller, an evaporating coil, a condenser, a compressor, and capillary tubes. The refrigeration unit provides cooling water or refrigerant, which absorbs heat through the evaporating coil to cool the beer to the desired temperature. The chiller stores the cooling water or refrigerant, maintaining stable operation of the refrigeration system. The refrigerant pipes in a beer dispenser primarily transfer cooling energy, transferring the cooling energy generated by the refrigeration unit to the beer, cooling it to a suitable drinking temperature. The refrigerant pipes are typically connected to the evaporating coil, transferring heat through the circulating refrigerant or cooling water.
[0003] In the prior art, the positions of the evaporator ice-making pipe and the beer heat exchange pipe are often not fixed, so that the ice formed in the evaporator pipe will freeze the beer pipe; inside some existing beer machines with additional positioning structures, the positioning structure of the evaporator pipe often affects the stirring of the water.

[0013] (III) Beneficial effects: Compared with the prior art, the present invention provides a heat exchange refrigeration pipe positioning structure for a beer machine, which has the following beneficial effects:
[0014] 1. This beer dispenser's heat exchange cooling tube positioning structure features upward-facing outer stoppers at both ends of the long stopper, and upward-facing inner stoppers at both ends of the short stopper. The distance between the outer stoppers is equal to the outer diameter of the spiral beer heat exchange tube, while the distance between the inner stoppers is smaller than the inner diameter of the spiral beer heat exchange tube and larger than the diameter of the stirring assembly. This structure utilizes two outer and two inner stoppers to position the spiral beer heat exchange tube, effectively preventing displacement or shaking of the tube during operation. This design ensures a constant, optimized spacing between the heat exchange tubes and the evaporator tubes, thereby maximizing heat exchange efficiency and allowing the beer to quickly and evenly reach the ideal cooling temperature. Controlling the position of the spiral beer heat exchange tubes on the bottom of the shell ensures the spacing between the spiral beer heat exchange tubes and the spiral evaporator tubes, so that ice formed on the evaporator tubes will not freeze the beer tubes. At the same time, while ensuring the stability of the heat exchange tubes, the positioning structure does not hinder the operation of the stirring assembly. The stirring assembly can rotate freely, fully stirring the water, promoting uniform mixing of the beer and the cooling medium, and further improving the cooling effect.
[0015] 2. The beer machine heat exchange refrigeration tube positioning structure, the short limit card seat and the long limit card seat are both hollow structures without a bottom surface, the long limit card seat is provided with an opening with the same width as the short limit card seat in the middle, the long limit card seat is sleeved on the top of the short limit card seat through the opening, and a base is installed under the short limit card seat, the length of the base is greater than the short limit card seat, and the short limit card seat and the base are fixedly connected; the intersection of the long limit card seat and the short limit card seat is fixedly connected to the base by bolts, and the two ends of the base are fixedly connected to the lower surface of the shell by bolts. Therefore, the long limit holder and the short limit holder are both mounted on the base. During manufacturing, it is only necessary to fix the base to the bottom surface of the shell, and then put the short limit holder and the long limit holder on the base in turn. Finally, use bolts and nuts to fix the intersection of the long limit holder and the short limit holder on the base to complete the installation. This design facilitates the replacement of the long limit holder and the short limit holder to adapt to spiral beer heat exchange tubes of different sizes.

[0025] 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.
[0026] like Figure 1-3As shown, the beer machine heat exchange refrigeration tube positioning structure is suitable for the beer machine, the beer machine includes a shell 1, a spiral beer heat exchange tube 2, a spiral evaporator tube 3 and a stirring assembly, the spiral beer heat exchange tube 2 and the spiral evaporator tube 3 are circular inside the beer machine, and the stirring assembly 4 is located in the middle of the spiral beer heat exchange tube 2; the structure includes a long limit holder 5 and a short limit holder 6, the long limit holder 5 and the short limit holder 6 are cross-mounted on the lower surface of the inner part of the shell 1 and are fixedly connected thereto, the spiral beer heat exchange tube 2 is placed above the long limit holder 5 and the short limit holder 6; the long limit holder 5 is designed with an upward-facing outer limit piece 501 at both ends, and the short limit holder 6 is designed with an upward-facing inner limit piece 601 at both ends, the distance between the outer limits is equal to the outer diameter of the spiral beer heat exchange tube 2, and the distance between the inner limit pieces 601 is smaller than the inner diameter of the spiral beer heat exchange tube 2 and larger than the diameter of the stirring assembly 4. This structure firmly limits the spiral beer heat exchange tube 2 through the combined action of two outer limiting plates 501 and two inner limiting plates 601, effectively avoiding displacement or shaking of the heat exchange tube during operation. This design ensures a constant and optimized spacing between the heat exchange tube and the evaporator tube, thereby maximizing the heat exchange efficiency and allowing the beer to quickly and evenly reach the ideal cooling temperature; controlling the position of the spiral beer heat exchange tube 2 on the bottom surface of the shell 1 ensures the spacing between the spiral beer heat exchange tube 2 and the spiral evaporator tube 3, so that ice formed in the evaporator pipeline will not freeze the beer pipeline; at the same time, while ensuring the stability of the heat exchange tube, this positioning structure does not cause any obstruction to the operation of the stirring component 4. The stirring component 4 can rotate freely, fully stir the water, promote the uniform mixing of beer and the cooling medium, and further enhance the cooling effect.
[0027] like Figure 1-2 As shown, the intersection point of the long limit holder 5 and the short limit holder 6 is located at the center of the spiral beer heat exchange tube 2.
[0028] like Figure 1-2As shown, the short limit card seat 6 and the long limit card seat 5 are both hollow structures without a lower bottom, the long limit card seat 5 is provided with an opening with the same width as the short limit card seat 6, the long limit card seat 5 is sleeved on the short limit card seat 6 through the opening, a base 7 is installed below the short limit card seat 6, the length of the base 7 is greater than that of the short limit card seat 6, and the short limit card seat 6 and the base 7 are fixedly connected; the long limit card seat 5 and the short limit card seat 6 are fixedly connected with the base 7 through bolts at the intersection, and the two ends of the base 7 are fixedly connected with the lower surface of the shell 1 through bolts. Therefore, the long limit card seat 5 and the short limit card seat 6 are both sleeved on the base 7, and during manufacturing, only the base 7 and the shell 1 bottom are fixed, then the short limit card seat 6 and the long limit card seat 5 are sequentially sleeved on the base 7, and finally the intersection of the long limit card seat 5 and the short limit card seat 6 is fixed on the base 7 through bolts and nuts, so that the installation is completed. This design facilitates replacement of the long limit card seat 5 and the short limit card seat 6, so as to adapt to different sizes of the spiral beer heat exchange pipe 2.
[0029] As shown in Figure 3 , the upper limit frame 8 of the spiral beer heat exchange pipe 2 is designed as a circle, the center of the upper limit frame 8 coincides with the center of the spiral beer heat exchange pipe 2, two or more upper limit pieces 801 are uniformly distributed on the circumference of the upper limit frame 8, the upper limit pieces 801 are downward, and the distance from the upper limit pieces 801 to the center of the upper limit frame 8 is the same as the radius of the spiral beer heat exchange pipe 2. One or more openings are provided on the surface of the upper limit frame 8 for liquid flow, so as to reduce the resistance generated during stirring.
[0030] As shown in Figure 4-5 , the spiral evaporator pipe 3 is located between the shell 1 and the spiral beer heat exchange pipe 2, the positioning clamping piece 9 is installed inside the spiral evaporator pipe 3, two or more clamping openings are designed on the side of the positioning clamping piece 9 connected with the spiral evaporator pipe 3, the distance between adjacent clamping openings is equal, and adjacent clamping openings are used to limit the adjacent rings of the spiral evaporator pipe 3 in the vertical direction; the other side of the positioning clamping piece 9 is fixedly connected with the shell 1. This design separately limits each ring of the spiral evaporator pipe 3, and the distance between adjacent rings is consistent, so that the refrigeration effect is more uniform under the premise of ensuring fixation.
[0031] As shown in Figure 5As shown, the size of the first bayonet from top to bottom of the positioning clamp 9 is three times the size of the remaining bayonet. Since one end of the spiral evaporator tube 3 needs to be connected to other equipment such as the evaporator, the first three turns of the spiral evaporator tube 3 require a certain degree of freedom of movement. This design ensures the stability of the limit and realizes the interaction between the spiral evaporator tube 3 and other equipment; the remaining bayonet sizes are the same, which are all the diameters of the single tube of the spiral evaporator tube 3, ensuring that the single tube of the spiral evaporator tube 3 is tightly connected to the bayonet.
[0032] like Figure 5 As shown, the positioning clamp 9 is made of PC material. Plastic is a material with low thermal conductivity. When the spiral beer heat exchange tube 2 is fixed on the inner wall of the shell 1, the heat transferred to the spiral beer heat exchange tube 2 through the positioning clamp 9 can be reduced, thereby improving the cooling efficiency.
