Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0030] Please see Figures 1-7 This utility model provides a technical solution:

[0031] A refrigeration and freezing unit with zoned temperature control includes a refrigeration unit 1 and a refrigerator assembly 2. A cold air delivery assembly 3 is fixedly connected to the right side of the refrigerator assembly 2, and an adjustment assembly 4 is fixedly connected to one side of the cold air delivery assembly 3. The cold air delivery assembly 3 includes a fixed cylinder 31, an electric fan 32 is fixedly connected to the inner side of the fixed cylinder 31, a vent hole 33 is opened at the upper end of the fixed cylinder 31, and a branch pipe 34 is fixedly connected to the outer side of the fixed cylinder 31. The adjustment assembly 4 includes a vent pipe 41, a vent hole 42 is opened at the left end of the vent pipe 41, and the vent pipe 4... A limiting telescopic rod 43 is fixedly connected to the inner side of the air cylinder 41. A column cylinder 44 is fixedly connected to the right side of the air cylinder 41. A semi-threaded rotating rod 45 is rotatably connected to the inner side of the air cylinder 41. An adjusting handle 46 is fixedly connected to the right side of the semi-threaded rotating rod 45. An internal thread plate 47 is spirally connected to the outer side of the semi-threaded rotating rod 45. A conical plug 48 is fixedly connected to the left side of the internal thread plate 47. A silicone sealing ring 49 is fixedly connected to the right end of the column cylinder 44. A branch pipe 34 is fixedly connected to the column cylinder 44. An extension pipe 5 is fixedly connected to the top of the fixed cylinder 31 near the air guide hole 33.

[0032] As a further implementation of this solution, the refrigerator component 2 includes a cabinet body 21. The cabinet body 21 has a partition groove 22 on its inner side. A rear partition 23 is fixedly connected to the right side of the cabinet body 21. A positioning hole 24 is opened on the inner side of the rear partition 23. The inner side of the positioning hole 24 is fixedly connected to the outer side of the vent 41. The number of positioning holes 24 corresponds one-to-one with the number of partition grooves 22. Through the above settings, this structural design realizes the basic layout of zoned temperature control. Each zone has an independent temperature control channel, which provides convenience for flexibly adjusting the temperature of each zone.

[0033] As a further implementation of this solution, a baffle 25 is fixedly connected to the right side of the rear partition 23. The right end of the baffle 25 has a ring-shaped scale 26 and a through hole on the inner side of the baffle 25. A semi-threaded rotating rod 45 is embedded in the through hole of the baffle 25 and extends out of the right end of the baffle 25. Through the above settings, the mechanical control of temperature regulation is realized through the design of the baffle 25 and the semi-threaded rotating rod 45. The rotation of the semi-threaded rotating rod 45 can precisely adjust the airflow, thereby achieving precise control of the zone temperature.

[0034] As a further implementation of this solution, the inner side of the extension pipe 5 is hollow, and the extension pipe 5 is connected to the air outlet of the refrigeration unit 1. The inner side of the fixed cylinder 31 is hollow, and the extension pipe 5 is connected to the inner side of the fixed cylinder 31 through the air guide hole 33. Through the above settings, the cold air can be smoothly delivered from the refrigeration unit to each zone, improving the refrigeration efficiency and the response speed of temperature control.

[0035] As a further implementation of this solution, a through hole is provided on the inner side of the fixed cylinder 31 near the branch pipe 34. The inner sides of both the branch pipe 34 and the column cylinder 44 are hollow structures. The inner side of the fixed cylinder 31 is connected to the inner side of the column cylinder 44 through the inner side of the branch pipe 34. The electric fan 32 is set at the right end of the through hole of the fixed cylinder 31. Through the above settings, the uniform distribution of cold air in the partition is achieved, ensuring that the temperature control of each partition is more uniform and stable.

[0036] As a further implementation of this solution, the inner side of the ventilator 41 is a hollow structure, and the inner side of the ventilator 41 is connected to the inner side of the column 44. Both the left and right ends of the column 44 are through-hole structures. The outer side of the semi-threaded rotating rod 45 is fitted to the inner side of the silicone sealing ring 49. A gap is provided between the outer side of the semi-threaded rotating rod 45 and the inner side of the column 44. A threaded hole is opened on the inner side of the internal threaded plate 47. A gap is provided between the outer side of the internal threaded plate 47 and the inner side of the ventilator 41. The left side of the limiting telescopic rod 43 is fixedly connected to the right side of the internal threaded plate 47. The center of the conical plug 48 is aligned with the center of the vent 42. The conical plug 48 is cone-shaped and extends out of the vent 42. Through the above arrangement, the dynamic adjustment of the cold air flow is realized, while preventing cold air leakage and improving the system's sealing and energy efficiency. Through the conical design of the conical plug 48 and the limiting action of the limiting telescopic rod 43, the fine adjustment of the cold air flow is realized. The movement of the cone can precisely control the flow of cold air, thereby achieving precise control of the zone temperature.

[0037] Workflow: When cooling the interior of the partition 22, cold air is generated by the refrigeration unit 1. The electric fan 32 is started to deliver the cold air from the refrigeration unit 1 to the interior of the fixed cylinder 31 through the extension pipe 5. The cold air is then delivered to the interior of multiple branch pipes 34 through the through holes in the fixed cylinder 31. The cold air enters the interior of the column cylinder 44 and the ventilation cylinder 41 through the branch pipes 34. Finally, the cold air is blown into the interior of the partition 22 through the ventilation holes 42, thereby achieving the effect of refrigerating the items inside the partition 22.

[0038] When different items are placed inside the partition groove 22, and the temperature inside the partition groove 22 needs to be adjusted accordingly, rotating the adjustment handle 46 drives the semi-threaded rotating rod 45 to rotate. A pointer is located on the right end of the adjustment handle 46. The temperature is controlled by aligning the pointer of the adjustment handle 46 with the ring scale 26. The adjustment handle 46 drives the semi-threaded rotating rod 45 to rotate. The semi-threaded rotating rod 45 is connected to the inside of the vent 41. The silicone sealing ring 49 seals the space between the column 44 and the semi-threaded rotating rod 45, preventing cold air from escaping between them. The rotation of the semi-threaded rotating rod 45 moves the internal thread plate 47 and the conical plug 48. The internal thread plate 47 causes the limiting telescopic rod 43 to extend or retract. The limiting telescopic rod 43 controls the extension or retraction of the internal thread plate 47. The plate 47 acts as a limiter when it moves. Since the conical plug 48 is cone-shaped, the more the conical plug 48 moves to the left, the further it moves into the vent 42. The space between the conical plug 48 and the vent 42 becomes smaller. Under constant pressure, the resistance to gas flow is greater, and the flow of cold air is less. This allows for targeted adjustment of the different compartments 22 for different goods. Based on the above principles, the device can adjust the flow of cold air according to the different goods in different compartments, thereby controlling the temperature of different compartments. This control method does not require a refrigeration unit for each compartment, reducing the cost, weight, and volume of the equipment, improving practicality, and simplifying the layout of the device.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
