Its main function is to mix fruit juice, sugar and other ingredients according to certain proportion, and then make cool and refreshing snow melting beverage through refrigeration and stirring. This machine usually has multiple functions, such as snow melting, cold drink, etc., and is easy to operate, fast in refrigeration speed, low in power consumption, and very suitable for making cold drink products such as fruit juice, soy milk and coconut milk.

Ice bucket is fixed on the machine body through screw, and ice sand barrel is fixed on the machine body through locking mechanism; after assembly, ice bucket is inside ice sand barrel. Ice bucket is the core component of snow melting machine, which is generally barrel type evaporator structure, and is provided with evaporation pipe body inside, which is arranged in S shape along the axis direction of evaporation barrel, forming a barrel body structure. This design makes the evaporation pipe body fully surround the evaporation barrel (ice bucket), improves the refrigeration speed and efficiency, and reduces the energy consumption of snow melting machine.

[0004] The working principle of the refrigeration system of snow melting machine can be summarized as follows:

[0008] S4: the above-mentioned saturated liquid refrigerant at normal temperature and high pressure absorbs its moisture and impurities through the drying filter;

[0009] S5: the above-mentioned saturated liquid refrigerant at normal temperature and high pressure, which removes moisture and impurities, is throttled and depressurized through the capillary tube to become wet steam at normal temperature and low pressure;

[0010] S6: the above-mentioned wet steam at normal temperature and low pressure starts to absorb heat and vaporize in the evaporator, reducing the temperature of the evaporator and the surrounding, and at the same time, the refrigerator becomes low-temperature and low-pressure gas;

[0034] The following embodiments are only for example. The embodiments can be combined, which are not limited to the content shown in the following single embodiment.

[0035] Please refer to Figure 1 The utility model provides a heat dissipation system of snow melting machine for reducing the temperature of refrigeration system in the refrigeration process.

[0036] As Figure 1As shown, the refrigeration system mainly includes compressor 5, exhaust pipe 4, condenser 1, drying filter, capillary, evaporator and return air pipe 3; the working steps of the refrigeration system are as follows:

[0037] S1: The compressor 5 works to compress the refrigerant into high-temperature and high-pressure refrigerant gas;

[0038] S2: The exhaust pipe 4 sends the above high-temperature and high-pressure refrigerant gas into the condenser 1 to dissipate heat;

[0039] S3: In the condenser 1, the high-temperature and high-pressure refrigerant gas releases heat and condenses into a normal-temperature, high-pressure saturated;

[0040] S4: The above normal-temperature, high-pressure refrigerant saturated liquid absorbs its moisture and impurities through the drying filter;

[0041] S5: The above normal-temperature, high-pressure refrigerant saturated liquid that removes moisture and impurities is throttled and depressurized by the capillary to become a normal-temperature, low-pressure wet steam;

[0042] S6: The above normal-temperature, low-pressure wet steam starts to absorb heat to vaporize in the evaporator, reducing the temperature of the evaporator and the surrounding, at the same time, the refrigerator also becomes a low-temperature, low-pressure gas;

[0043] S7: The above low-temperature, low-pressure refrigerant gas passes through the return air pipe 3 and returns to the compressor 5 again.

[0044] Repeat the above process to transfer the heat of the liquid in the ice slurry cylinder to the air, achieving the purpose of refrigeration.

[0046] As Figure 1As shown, the difference between the heat dissipation system and the prior art is that the heat dissipation system further comprises a compressor fan 8 and a temperature detector 6, both of which are installed beside the compressor 5 of the refrigeration system; the compressor fan 8 starts to work when the temperature detector 6 detects that the temperature is greater than a first set value; the compressor fan 8 stops to work when the temperature detector 6 detects that the temperature is less than a second set value; the first set value is greater than the second set value; in a high-temperature environment, for example, when the ambient temperature is above 43℃, the temperature detector 6 detects that the temperature of the compressor 5 rises to the first set value, the compressor fan 8 can start in time to increase the air flow inside the snow melting machine and reduce the temperature of the compressor 5, thereby avoiding the shutdown of the compressor 5 due to the temperature rising to the shutdown protection temperature, and ensuring that the compressor 5 can still continue to work in a high-temperature environment; when the temperature detector 6 detects that the temperature of the compressor 5 decreases to the second set value, the compressor 5 can also stop working in time, without additional energy consumption, achieving the purpose of energy saving.

[0047] As shown in Figure 1 , the difference between the heat dissipation system and the prior art is also that the air inlet is arranged at the side of the snow melting machine, and the air outlet is arranged at the rear of the snow melting machine, avoiding the design of the air outlet at the side of the snow melting machine in the prior art, which causes an unfriendly experience for the user.

[0048] As shown in Figure 1 , it is to be explained that the condenser fan 2 starts to work when the compressor 5 is turned on, and stops to work when the compressor 5 is turned off; the motor fan also starts or stops to work according to the start or stop of the motor.

[0049] The compressor fan 8 starts to work under two prerequisite conditions, one is that the compressor 5 is also turned on, and the other is that the temperature detector 6 detects that the temperature is higher than the first set value.

[0050] If the compressor 5 is stopped to work, the compressor fan 8 is not working regardless of whether the temperature detected by the temperature detector 6 is higher than the first set value.

[0051] In another embodiment, please refer to Figure 1 , the condenser 1 is installed at the rear of the snow melting machine, which cooperates with the design of the air outlet to enhance the heat dissipation effect of the condenser fan 2.

Compared with a single-sided air inlet, the left air inlet 72 and the right air inlet 73 are respectively opened on both sides, and the heat dissipation effect is better.

[0054] In another embodiment, please refer to Figure 2 The heat dissipation system further includes a support air inlet 71 opened on the side of the support of the snow melting machine, further enhancing the heat dissipation effect of the heat dissipation system.

[0055] In another embodiment, the first set value is 55℃, and the second set value is 50℃, which is the initial set value, which can be adjusted later according to needs; this embodiment provides a numerical selection of the first set value and the second set value, and designers can adaptively adjust the two values according to the compressor 5 shutdown protection temperature, external environment, and other factors.

[0056] In other embodiments, as Figure 1 The temperature probe 6 is installed above the compressor 5, ensuring the accuracy and timeliness of the detected temperature; the compressor fan 8 is installed in front of the compressor 5, improving the heat dissipation effect of the compressor fan 8.

[0057] In conclusion, the utility model discloses the design through the compressor fan 8 and temperature detector 6 of compressor 5 side, in high temperature environment, for example, when the temperature detector 6 detects that the temperature of compressor 5 rises to the first set value when environmental temperature is 43 DEG C or more, compressor fan 8 can start in time, increase the air flow in the inside of snow melting machine, reduce the temperature of compressor 5, thereby avoid the temperature of compressor 5 to stop and shut down to stop when rising to protection temperature, thereby ensure that in high temperature environment, compressor 5 still can keep working continuously, and when the temperature detector 6 detects that the temperature of compressor 5 reduces to the second set value, compressor 5 can also stop working in time, will not consume extra energy, reaches the purpose of energy saving, simultaneously through the design that the air inlet is set in the side portion of snow melting machine, the air outlet is set in the rear portion of snow melting machine, avoided the design of the air outlet in the side portion of snow melting machine in prior art, caused the problem of unfriendly experience to user, so, the utility model discloses effectively overcome the shortcoming in the prior art and has higher industrial utilization value.
