[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 9 This utility model provides a technical solution: an ice cream machine with a constant temperature storage compartment, comprising: a shell 1; a storage compartment 4 disposed inside the shell 1; an inner spiral cooling water pipe 5 fixedly connected to the inside of the storage compartment 4; an arc-shaped cold air box 10 symmetrically fixedly connected to the inside of the storage compartment 4, with multiple air blowers 11 equidistantly arranged at the bottom of the arc-shaped cold air box 10; a cold air insulation inlet pipe 12 fixedly connected to the top of the arc-shaped cold air box 10, and the cold air insulation inlet pipe 12 fixedly connected to the storage compartment 4; and an air collecting box 14 disposed on the top of the storage compartment 4, with one end of the cold air insulation inlet pipe 12 connected to the storage compartment 4. An air collection box 14 is fixedly connected, and an evaporator 15 is provided on one side of the air collection box 14. An air blowing box 16 is fixedly installed on one side of the evaporator 15 by bolts. Two centrifugal fans 18 are installed on one side of the air blowing box 16, and the output end of the centrifugal fans 18 is connected to the air blowing box 16 through an air duct. A side recovery box 7 is fixedly connected to the outside of the storage chamber 4. Multiple circulating heat-insulating air ducts 8 are fixedly connected to the inside of the side recovery box 7, and the circulating heat-insulating air ducts 8 are fixedly connected to the storage chamber 4. A circulation section is provided on one side of the storage chamber 4, and the input end of the centrifugal fans 18 and the side recovery box 7 are both connected to the circulation section.

[0032] It should be noted that in this embodiment, the refrigeration unit 3 consists of core components such as a compressor, condenser, expansion valve, and evaporator 15. The compressor compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas. The refrigerant gas then enters the condenser, where it releases heat to the external environment and condenses into a high-pressure liquid. After the high-pressure liquid is throttled and depressurized by the expansion valve, it becomes a low-temperature, low-pressure liquid refrigerant and enters the evaporator 15. Inside the evaporator 15, the liquid refrigerant absorbs heat from the surrounding environment and evaporates into gas, thereby achieving a cooling effect. The refrigerant gas is then drawn back into the compressor, completing one refrigeration cycle. The inner spiral cooling water pipe 5 is fixedly connected to the inside of the storage compartment 4 and is connected to the refrigeration unit 3. Low-temperature refrigerant flows through the inner spiral cooling water pipe 5, exchanging heat with the ice cream ingredients in the storage chamber 4 through the pipe wall, absorbing heat from the ingredients and lowering their temperature. The evaporator 15 is located on one side of the air collection box 14. When the refrigerant evaporates in the evaporator 15, it absorbs heat from the surrounding air, lowering the air temperature. The blower box 16 is bolted to one side of the evaporator 15. Two centrifugal fans 18 are installed on one side of the blower box 16. The output ends of the centrifugal fans 18 are connected to the blower box 16 via ducts. After the centrifugal fans 18 start, they draw the cooled air around the evaporator 15 into the blower box 16, and then deliver it through the cold air insulated inlet pipe 12 to the arc-shaped cold air box 10. The arc-shaped cold air box 10 is symmetrically fixed inside the storage chamber 4, and multiple blowers 11 are equidistantly arranged at its bottom. Cold air is blown out from the blowers 11, directly acting on the ice cream ingredients in the storage chamber 4, further lowering the ingredient temperature and ensuring the ingredients are in a constant low-temperature environment. A circulation section is provided. On one side of the storage chamber 4, when the centrifugal fan 18 is working, in addition to blowing the cold air around the evaporator 15 into the storage chamber 4, it also recovers some air from the side recovery box 7 through the side ventilation box 17 and the bottom air inlet box 19. Multiple circulating insulated air ducts 8 are fixedly connected to the inside of the side recovery box 7. The circulating insulated air ducts 8 are fixedly connected to the storage chamber 4. The recovered air re-enters the system through the circulating insulated air ducts 8, forming a complete air circulation path. This circulation method effectively recovers and utilizes heat or cold, improves energy utilization efficiency, reduces energy consumption, and at the same time ensures the stability and uniformity of the temperature inside the storage chamber 4. A side sealing cover 21 is bolted to one side of the bottom air inlet box 19. A filter screen 20 is fixedly connected to one side of the side sealing cover 21. A side sealing frame 24 that cooperates with the side sealing cover 21 is fixedly connected to one side of the bottom air inlet box 19. The filter screen 20 can filter dust, impurities, etc. in the air entering the system, ensuring the cleanliness of the circulating air and preventing impurities from entering the storage chamber 4 and affecting the quality of ice cream raw materials.The side sealing cover 21 cooperates with the side sealing frame 24 to facilitate the disassembly and installation of the filter screen 20, making it easy to clean and replace the filter screen 20, ensuring the filtration effect and extending the service life of the equipment. A protective net 9 is installed inside the circulating insulated air duct 8 to prevent foreign objects from entering the duct during circulation, affecting the normal operation of the circulation system. It also protects the internal structure of the duct, improving the safety and reliability of the equipment. Multiple ventilation holes are provided inside the shell 1, and a cooling fan 6 is installed. The refrigeration unit 3 generates heat during operation, and the cooling fan 6 dissipates the heat from inside the shell 1 to the external environment through the ventilation holes, ensuring that the refrigeration unit 3 operates in a suitable temperature environment and preventing equipment failure or performance degradation due to overheating. Two feed boxes 23 are fixedly connected to the top of the shell 1. The feed boxes 23 are connected to the storage chamber 4 via a material pipe. The top of the feed boxes 23... The container is equipped with a feed cover 25 and two feed boxes 23, which can store different flavors or types of ice cream ingredients respectively, making it convenient to add and mix them according to needs. The ingredients can smoothly enter the storage chamber 4 for storage through the feed pipe. An ice cream dispensing component 2 is provided on one side of the shell 1. An ice cream feed pipe 13 is fixed to the bottom of the storage chamber 4. One end of the ice cream feed pipe 13 is connected to the ice cream dispensing component 2. When ice cream needs to be made, the ingredients stored at a constant temperature in the storage chamber 4 are transported to the ice cream dispensing component 2 through the ice cream feed pipe 13. The ice cream dispensing component 2 makes the ingredients into ice cream and outputs it, making it convenient for users to obtain the made ice cream and ensuring the continuity of ice cream making. In this application, except for the copper pipe of the evaporator 15 and the outside of the inner spiral cooling water pipe 5, the other pipes connecting the cold air and refrigerant and the outside of the storage chamber 4 are all equipped with heat insulation material.
