[0032] As shown in FIG. 1, the utility model embodiment provides a cold drink preparation system, which is applied to a beverage preparation device, and comprises:

[0033] a beverage brewing module 8;

[0034] a refrigeration assembly, comprising a refrigerator and an evaporator 5 connected with the refrigerator, the evaporator 5 being connected with the beverage brewing module 8 at the same time, for obtaining brewed beverage and refrigerant, and the brewed beverage being capable of exchanging heat with the refrigerant after passing through the evaporator 5, thereby reducing its own temperature to obtain cold drink;

[0035] In the refrigeration assembly, a first anti-freezing assembly for preventing the beverage remaining in the evaporator 5 from freezing is further arranged, and a second anti-freezing assembly for preventing the beverage remaining in the evaporator 5 from freezing is further arranged between the beverage brewing module 8 and the evaporator 5.

[0036] For example, after the beverage brewing module 8 in the embodiment prepares the beverage according to the normal procedure, the beverage is delivered to the refrigeration assembly to generate cold drink after being cooled by the refrigeration assembly, and the user can enjoy the cold drink. The process is fast, and the user does not need to wait for a long time. In the embodiment, the refrigeration assembly uses a refrigerator to prepare refrigerant, and then uses the evaporator 5 to exchange heat between the beverage and the refrigerant. The process is fast, and the high-temperature beverage can be quickly cooled to a lower temperature to form cold drink. In addition, in the embodiment, the first anti-freezing assembly is arranged in the refrigeration assembly to prevent the beverage remaining in the evaporator 5 from freezing, and the second anti-freezing assembly is arranged between the beverage brewing module 8 and the evaporator 5. Through the two anti-freezing assemblies, the beverage remaining in the evaporator 5 can be effectively prevented from freezing, and the use of the evaporator 5 can be affected.

[0037] Based on the above embodiment, the embodiment has the beneficial effects of simple overall structure of the cold drink preparation system, easy preparation, fast cooling of the beverage prepared by the refrigeration assembly, prevention of freezing of the beverage remaining in the evaporator 5 under the action of the anti-freezing assembly, and significant improvement of the user experience of the beverage preparation device. The user can quickly obtain cold drink without waiting for a long time.

[0038] In an embodiment, the refrigerator is a compressor 1. The refrigeration assembly further comprises a condenser 2, and the refrigerant prepared by the refrigerator flows to the evaporator 5 through the condenser 2.

[0039] Further, the refrigeration assembly further comprises a throttling mechanism 3, and the refrigerant prepared by the refrigerator flows to the evaporator 5 through the throttling mechanism 3.

[0040] As shown in Fig. 1, the refrigeration component includes a refrigerator, an evaporator 5, a condenser 2 and a throttling mechanism 3 connected by refrigerant delivery pipelines, and the first anti-freezing component is based on a bypass pipeline and arranged between the evaporator 5 and the condenser 2.

[0041] Specifically, the first anti-freezing component includes a solenoid valve 4, when the cold beverage preparation is completed, the refrigerator stops running, the solenoid valve 4 is opened, the heat-exchanged refrigerant flowing out of the condenser 2 enters the evaporator 5 through the solenoid valve 4, so that the temperature in the evaporator 5 rises, thereby preventing the beverage in the evaporator 5 from freezing.

[0042] The beverage delivery pipeline is arranged between the beverage brewing module 8 and the liquid inlet of the evaporator 5, and the second anti-freezing component is arranged on the beverage delivery pipeline.

[0043] The second anti-freezing component includes an air pump 6, when the cold beverage preparation is completed, the air pump 6 is started to deliver air flow into the evaporator 5 to purge the pipeline in the evaporator 5, thereby preventing the residual beverage in the evaporator 5 from freezing.

[0044] In order to prevent the air pump 6 from backflowing, a one-way valve 7 is arranged on the beverage delivery pipeline between the beverage brewing module 8 and the air pump 6.

[0045] Based on the above embodiments, the present embodiment adds a bypass solenoid valve 4 to the refrigerant delivery pipeline, so that when the cold beverage preparation is completed and the compressor 1 stops working, the warmed refrigerant can be returned to the evaporator 5, the temperature of the evaporator 5 instantaneously rises, thereby preventing the residual coffee liquid in the evaporator from freezing; at the same time, the air pump 6 can be controlled by a program to purge the residual beverage in the evaporator 5, thereby further reducing the residual beverage and preventing freezing.

[0046] Continuing to combine Fig. 1, taking coffee as an example, when ice coffee is made, the refrigeration system runs, and the refrigerant flows as follows: compressor 1→condenser 2→throttling mechanism 3→evaporator 4→compressor 1; the coffee liquid flows as follows: beverage brewing module 8→one-way valve 7→evaporator 4. In this mode, the 85℃ coffee liquid flowing through the evaporator 4 can be quickly cooled to below 10℃.

[0047] When the ice coffee preparation is completed, the compressor 1 stops, the refrigerant flows as follows: condenser 2→solenoid valve 4→evaporator 5→compressor 1, and the air pump 6 on the beverage delivery pipeline works, and the gas flows as follows: air pump 6→evaporator 5. In this mode, the high-temperature refrigerant flows through the evaporator 5 back to the compressor, the surface temperature of the evaporator 5 instantaneously rises, thereby preventing the coffee liquid in the evaporator 5 from freezing, and at the same time, the air pump 6 purges the pipeline in the evaporator 5, thereby preventing the coffee liquid from remaining and further preventing the coffee liquid from freezing.

[0048] The utility model discloses another embodiment simultaneously provides a kind of beverage preparation equipment, including the cold beverage preparation system as any one embodiment described above.

[0049] In actual application, user presses the coffee button, and the beverage brewing module 8 starts to grind beans and prepare for brewing, while the compressor 1 starts to run and refrigerate, and the air pump 6 starts to run synchronously to purge the evaporator pipeline through which the coffee liquid flows. When the surface temperature of the evaporator 5 reaches the set value, the coffee starts to brew, and the air pump 6 is closed. The 85℃ high-temperature coffee liquid is cooled by flowing through the evaporator 5 and then flows out into the user's cup. After the coffee liquid is finished, the air pump 6 is started to purge the evaporator 5 pipeline through which the coffee liquid flows, to ensure that there is no coffee liquid residue in the evaporator 5, and at the same time, the compressor 1 is closed, the bypass electromagnetic valve 4 is opened, and the high-temperature refrigerant in the condenser 2 enters the evaporator 5 through the bypass electromagnetic valve 4, so that the surface temperature of the evaporator 5 rises, preventing the coffee liquid remaining in the pipeline of the evaporator 5 from freezing due to supercooling.

[0050] The above embodiments are only exemplary embodiments of the utility model, and are not used to limit the utility model. The protection scope of the utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the utility model within the spirit and protection scope of the utility model, and such modifications or equivalent replacements should also be considered to fall within the protection scope of the utility model.
