Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and specifically provides a refrigeration device. Background Technology

[0002] French dual-system refrigerators typically place the evaporator between the refrigerator compartment and the freezer compartment. The refrigerator cooling circuit, ice-making circuit, and throttling capillary tube are connected to the evaporator after being combined, so as to simultaneously supply cooling capacity to the refrigerator compartment, freezer compartment, and ice-making mechanism.

[0003] In existing French dual-system refrigerators, the evaporator inlet is located on the side of the evaporator near the rear of the cabinet. The refrigerant piping converges and is directly welded to the evaporator from the rear of the cabinet, reducing the complexity of piping layout. However, this design places the welding point between the refrigerant piping and the evaporator inlet in a deep, enclosed area within the cabinet. During assembly and welding, operators can only insert welding tools through an opening on the front of the cabinet for accessing items. Furthermore, the limited operating space and obstructed view within the enclosed area make welding difficult, easily leading to assembly defects such as incomplete or missed welds. This results in a high overall repair rate, poor production efficiency and product reliability, severely impacting the user experience. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the welding of existing refrigeration evaporators and refrigeration pipelines is unreliable, resulting in poor product reliability and affecting user experience.

[0005] This invention provides a refrigeration device, comprising:

[0006] The box has an opening for taking out and putting in items, and a freezer compartment is formed inside the box;

[0007] A partition is disposed in the freezer compartment, and the partition divides the freezer compartment into a first compartment and a second compartment distributed to the left and right;

[0008] A refrigerated evaporator is disposed within the partition, and the distance from the evaporator inlet to the opening is less than the distance from the evaporator inlet to the back panel of the housing;

[0009] The refrigeration pipe is disposed inside the housing and located in an area of ​​the housing away from the opening. The refrigeration pipe extends toward the opening and is welded to the evaporator inlet near the opening.

[0010] An ice-making component is disposed inside the housing and is connected to the freezer evaporator via the refrigeration piping.

[0011] By placing the evaporator inlet of the refrigeration evaporator on the side closest to the opening, the refrigeration piping extends forward from the area of ​​the housing away from the opening and is welded to the evaporator inlet near the opening. The welding point is moved forward to the front area of ​​the housing, allowing operators to directly view the welding point through the front opening of the housing without having to reach into the narrow compartments deep inside the housing. This provides a wide field of vision and ample operating space, significantly reducing the difficulty of piping welding, effectively reducing assembly defects such as incomplete welds and missing welds, lowering the overall machine rework rate, and improving the assembly efficiency of the production line and the reliability of the product's refrigeration circuit.

[0012] In the preferred embodiment of the above-mentioned refrigeration equipment, the refrigeration equipment further includes an inner liner, which is disposed in the cabinet body and forms the freezing chamber inside the inner liner. A first installation space is formed between the inner liner back panel and the cabinet back panel. The refrigeration pipe is disposed in the first installation space and extends through the inner liner and extends inside the inner liner to communicate with the evaporator inlet.

[0013] This setup provides a specific structure for a refrigeration device.

[0014] In the preferred embodiment of the above-mentioned refrigeration equipment, the refrigeration pipeline extends through the inner liner back plate and then extends within the partition.

[0015] The partition is centrally located inside the liner, allowing the refrigeration pipes to extend centrally and directly to the evaporator inlet at the front. The welding points are centrally aligned with the opening on the front of the cabinet, ensuring unobstructed visibility for operators and more precise welding positioning, further reducing the assembly defect rate of incomplete or misaligned welds.

[0016] In the preferred embodiment of the above-mentioned refrigeration equipment, the extension length of the refrigeration pipeline within the inner liner is greater than or equal to a first preset value.

[0017] By limiting the extension length, welding space is ensured for the welding process of refrigeration pipes and evaporator inlet, thus guaranteeing welding reliability.

[0018] In the preferred embodiment of the above-mentioned refrigeration equipment, a foam layer is provided between the inner liner and the box body, and the refrigeration pipeline is disposed within the foam layer.

[0019] The foam layer isolates the low-temperature pipeline from the humid and hot ambient air, reducing the problem of condensation and dripping water on the back panel and side panel of the enclosure from the source. There is no need to add a large area of ​​insulation foam, simplifying the assembly process of anti-condensation pipeline.

[0020] In the preferred embodiment of the above-mentioned refrigeration equipment, a compressor cavity is formed inside the housing, the compressor cavity is located in the lower rear part of the housing, and the height from the welding position of the refrigeration pipeline and the evaporator inlet to the compressor cavity is greater than or equal to 300mm.

[0021] By limiting the height, the operating space during welding operations is guaranteed.

[0022] In the preferred embodiment of the above-mentioned refrigeration equipment, the refrigeration piping includes a first connecting pipe for connecting to an ice-making component or a refrigeration evaporator, a second connecting pipe for connecting to a condenser, and a manifold. The first connecting pipe and the second connecting pipe are both connected to the manifold, and the acute angle α formed between the first connecting pipe and the manifold is in the range of 15° to 60°; and / or, the acute angle β formed between the second connecting pipe and the manifold is in the range of 15° to 60°.

[0023] By controlling the angle between the first and second connecting pipes and the manifold within the acute angle range of 15° to 60°, the flow direction of the refrigerant is smoothly transitioned when they converge, avoiding eddies and turbulence problems caused by the vertical convergence of pipes, effectively reducing the flow resistance of the refrigerant, improving the efficiency of the refrigeration cycle, and shortening the cooling time for refrigeration, freezing, and ice making.

[0024] In the preferred embodiment of the above-mentioned refrigeration equipment, the connection point between the first connecting pipe and the manifold is located in the area of ​​the cabinet away from the opening or in the freezer room.

[0025] When the junction point is located in the rear area of ​​the enclosure away from the opening, multiple branch pipes are centrally stored in the back foamed jacket, which facilitates centralized coverage of the anti-condensation structure and makes the assembly process centralized and efficient.

[0026] In the preferred embodiment of the above-mentioned refrigeration equipment, the connection point between the second connecting pipe and the manifold is located in the area of ​​the cabinet away from the opening or in the freezer room.

[0027] By utilizing a low-temperature freezing chamber to accommodate multiple pipe manifolds, the manifolds only need to extend a short distance forward to connect with the evaporator inlet near the opening, significantly reducing the area of ​​exposed low-temperature pipes, effectively suppressing condensation and water accumulation inside the inner tank, and improving the overall reliability of the unit.

[0028] In the preferred embodiment of the above-mentioned refrigeration equipment, the refrigeration equipment further includes a refrigeration evaporator and an ice-making component. The cabinet also forms a refrigeration compartment, which is located on one side of the freezer compartment. The ice-making component is disposed in the refrigeration compartment, and both the refrigeration evaporator and the ice-making component are connected to the refrigeration pipeline.

[0029] This setup provides a specific structure for a refrigeration device.

[0030] In the preferred embodiment of the above-mentioned refrigeration equipment, the refrigeration equipment further includes a compressor, a condenser, a refrigeration throttling mechanism, and an ice-making throttling mechanism. The compressor, the condenser, the refrigeration throttling mechanism, and the refrigeration evaporator constitute a refrigeration cycle. The compressor, the condenser, the ice-making throttling mechanism, the ice-making component, the refrigeration evaporator, and the refrigeration evaporator constitute an ice-making refrigeration cycle.

[0031] The two cycles share the compressor and condenser, reducing the number of core heat exchange components, simplifying the overall piping layout, and lowering equipment material and assembly costs. The refrigeration cycle can supply cooling to the evaporator independently to meet the continuous low-temperature storage requirements of the freezer chamber, while the ice-making and refrigeration cycle can simultaneously supply refrigerant to the evaporator and ice-making components, taking into account both refrigeration and ice-making functions. The two operating conditions can be independently controlled without interference, providing greater flexibility in temperature control.

[0032] In the preferred embodiment of the above-mentioned refrigeration equipment, an anti-condensation structure is provided on the refrigeration pipeline.

[0033] The anti-condensation structure prevents condensation from forming on the cooling pipes, significantly improving the overall reliability and user experience.

[0034] In the preferred embodiment of the above-mentioned refrigeration equipment, a water receiving tray is provided below the refrigeration evaporator, and the water receiving tray is inclined.

[0035] The inclined water receiving tray can promptly collect the defrosting water generated during evaporator operation. The slope formed by the inclined tray guides the water flow in a specific direction to avoid the accumulation of water at the bottom of the evaporator.

[0036] In the preferred embodiment of the above-mentioned refrigeration equipment, the ice-making component includes an ice-making container, an ice-making evaporator, and an ice-storage container. The ice-making container is movably disposed within the housing. At least a portion of the ice-making evaporator is adapted to extend into the ice-making container. The ice-storage container is disposed within the housing and located below the ice-making evaporator to receive ice blocks on the ice-making evaporator. The ice-making evaporator is connected to the refrigeration pipeline. When the refrigeration equipment is making ice, the ice-making container moves to a position below the ice-making evaporator, and at least a portion of the ice-making evaporator is located within the ice-making container. When the refrigeration equipment is de-icing, the ice-making container moves to a clearance position so that the ice blocks on the ice-making evaporator fall into the ice-storage container.

[0037] Ice is made by extending part of the ice evaporator into the ice-making container. After ice is made, the ice-making container is moved to a clearance position, so that the ice on the ice evaporator falls and is caught by the ice storage container for easy access by the user.

[0038] In the preferred embodiment of the above-mentioned refrigeration equipment, the ice-making evaporator includes a distribution component and a plurality of ice-making columns connected to the distribution component. The distribution component is connected to the refrigeration pipeline. When the refrigeration equipment is making ice, at least a portion of the ice-making columns can extend into the ice-making container.

[0039] The distributor can be used to introduce low-temperature refrigerant into the ice-making column for ice making, and it can also introduce high-temperature refrigerant into the ice-making column for de-icing.

[0040] With the above technical solution, the present invention arranges the evaporator inlet of the refrigeration evaporator on the side close to the opening of the housing. The refrigeration pipeline extends forward from the area of ​​the housing away from the opening and is welded to the evaporator inlet near the opening. The welding point is moved forward to the front area of ​​the housing. The operator can directly see the welding point through the front opening of the housing without having to reach into the deep and narrow compartments of the housing. The operator has a wide field of vision and sufficient operating space, which greatly reduces the difficulty of pipeline welding, effectively reduces assembly defects such as false welding and missing welding, reduces the overall machine rework rate, and improves the assembly efficiency of the production line and the reliability of the product refrigeration circuit.

Detailed Implementation

[0053] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0054] It should be noted that the terms indicating directions or positional relationships in the description of this invention are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] Furthermore, to better illustrate the technical solution of the present invention, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that the present invention can still be implemented without certain specific details. In some examples, refrigeration principles and other aspects well-known to those skilled in the art are not described in detail, in order to highlight the main points of the present invention.

[0056] As the background technology shows, in existing French dual-system refrigerators, the evaporator inlet is located on the side of the evaporator near the rear of the cabinet. The refrigeration pipes converge and are directly welded to the evaporator from the rear of the cabinet, thus reducing the difficulty of pipe layout. However, this structure places the welding point between the refrigeration pipes and the evaporator inlet in a deep, enclosed area within the cabinet. During assembly and welding, operators can only insert welding tools through the opening on the front of the cabinet for accessing items. Furthermore, the limited operating space and obstructed view within the enclosed area make welding difficult, easily leading to assembly defects such as incomplete welds and missed welds. This results in a high overall repair rate, poor production efficiency and product reliability, severely impacting the user experience.

[0057] Therefore, such as Figures 1 to 9 As shown, the present invention provides a refrigeration device, comprising: a housing 1, wherein the housing 1 has an opening 11 for placing and removing items, and a freezer compartment 13 is formed inside the housing 1; a partition 14, wherein the partition 14 is disposed within the freezer compartment, and the partition 14 divides the freezer compartment 13 into a first compartment 131 and a second compartment 132 distributed to the left and right; and a freezer evaporator 2, wherein the freezer evaporator 2 is disposed within the partition 14, and the distance from the evaporator inlet 21 of the freezer evaporator 2 to the opening 11 is... The distance from the evaporator inlet 21 to the back plate of the housing 1 is less than the distance from the evaporator inlet 21 to the back plate of the housing 1; refrigeration pipe 3, which is disposed inside the housing 1 and located in the area of ​​the housing 1 away from the opening 11, extends towards the opening 11 and is welded to the evaporator inlet 21 near the opening 11; ice-making assembly 7, which is disposed inside the housing and is connected to the freezer evaporator 2 through the refrigeration pipe 3. By arranging the evaporator inlet 21 of the refrigeration evaporator 2 on the side close to the opening 11, the refrigeration pipe 3 extends forward from the area of ​​the housing 1 away from the opening 11 and is welded to the evaporator inlet 21 near the opening 11. The welding point is moved forward to the front area of ​​the housing 1, and the operator can directly see the welding point through the front opening 11 of the housing 1 without having to reach into the narrow interlayer of the housing 1. The operation field is wide and the operating space is sufficient, which greatly reduces the difficulty of pipe welding, effectively reduces assembly defects such as false welding and missing welding, reduces the overall machine rework rate, and improves the assembly efficiency of the production line and the reliability of the product refrigeration circuit.

[0058] like Figure 1 and Figure 2 As shown, Figure 1 This is a front view of the refrigeration equipment. Figure 2 This is a top view of the refrigeration equipment. Figure 1 In the middle, the opening 11 of the cabinet 1 is located at the front. As can be seen from the diagram, the upper part is the refrigerator compartment 12, and the lower part is the freezer compartment 13. A partition 14 is centrally located within the freezer compartment 13, dividing it into a first compartment 131 on the left and a second compartment 132 on the right. The refrigeration pipes 3 are located at the back of the cabinet 1 and are thus concealed. Figure 2 As can be seen, the part connecting the refrigeration pipe 3 and the evaporator 2 extends towards the opening 11, so that the refrigeration pipe 3 and the evaporator inlet 21 can be welded directly at the opening 11. Operators can directly observe and operate, which overcomes the problem of welding in the narrow interlayer behind the cabinet 1 in the prior art, effectively avoids assembly defects such as false welding and missing welding, and improves the reliability of refrigeration equipment and the user experience.

[0059] The refrigeration equipment also includes an inner liner 4, which is disposed within the cabinet 1. The inner liner 4 forms the freezing compartment 13. A partition 14 is disposed within the inner liner 4. A first installation space 51 is formed between the inner liner back panel 41 of the inner liner 4 and the cabinet back panel 15 of the cabinet 1. The refrigeration pipe 3 is disposed within the first installation space 51, and extends through the inner liner 4 to connect with the evaporator inlet 21. By providing the inner liner 4, the items to be stored are separated from the refrigeration pipe 3, avoiding the refrigeration pipe 3 from occupying space and preventing accidental damage to the refrigeration pipe 3, thus improving the space utilization and reliability of the refrigeration equipment. Furthermore, a foam layer is provided within the first installation space 51, which can wrap around the refrigeration pipe 3, thereby providing insulation and protection for the refrigeration pipe 3, reducing the loss of cold air from the low-temperature refrigeration pipe 3, and lowering the energy consumption of the refrigeration equipment.

[0060] As one implementation method, such as Figure 2 As shown, the refrigeration pipe 3 extends through the inner liner back plate 41 and then within the partition 14. The partition 14 is centrally located within the inner liner, allowing the refrigeration pipe 3 to extend centrally to the front evaporator inlet 21. The welding point is centered and aligned with the front opening 11 of the housing 1. Preferably, the welding point is located in the middle of the opening 11, ensuring operable space within the vertical and horizontal range of the welding point, unobstructed visibility for the operator, and more precise welding positioning, further reducing the assembly defect rate of incomplete or misaligned welds. Moreover, the refrigeration pipe 3 exits straight through the inner liner back plate 41, reducing its length and bends, thereby reducing refrigerant flow resistance and improving the refrigeration cycle efficiency of the refrigeration equipment.

[0061] The extension length of the refrigeration pipe 3 within the inner liner 4 is greater than or equal to a first preset value. By limiting the extension length, the refrigeration pipe 3 has sufficient length after entering the inner liner 4, so that the end of the refrigeration pipe 3 is as far away from the wall of the inner liner 4 as possible, providing sufficient operating field of vision and working space for welding operations, ensuring welding space for the welding process of the refrigeration pipe 3 and the evaporator inlet 21, and ensuring welding reliability.

[0062] Optionally, the first preset value ranges from 50mm to 200mm, preferably 100mm. This first preset value is set based on the space requirements during welding operations. At this size, the welding torch can be inserted and manually aligned, effectively avoiding the problems of incomplete or missed welds caused by limited space and obstructed vision in the deep interlayer of existing technologies. Simultaneously, this size avoids unnecessary bends in the refrigeration pipes, ensuring adequate resistance to refrigerant flow and improving the compactness of the refrigeration equipment's piping layout.

[0063] Furthermore, a compressor chamber 16 is formed within the housing 1, and the compressor chamber 16 is located in the lower rear part of the housing 1, such as... Figure 3 and Figure 4 As shown, the height from the welding position of the refrigeration pipe 3 and the evaporator inlet 21 to the compressor cavity 16 is greater than or equal to 300mm. Maintaining a vertical distance of no less than 300mm between the welding point and the bottom compressor cavity 16 ensures that the welding torch and arm's vertical movement are not obstructed by the bottom compressor cavity 16 during welding operations, further optimizing the ease of welding operations at the front opening 11.

[0064] In the preferred embodiment of the above-mentioned refrigeration equipment, a foam layer is provided between the inner liner 4 and the cabinet 1, and the refrigeration pipes 3 are disposed within the foam layer. That is, a foam layer is provided within the first installation space 51. This foam layer isolates the low-temperature pipes from contact with the humid and hot ambient air, reducing condensation and dripping problems on the cabinet back panel 15 and side panels from the source. This eliminates the need for additional large-area insulation foam, simplifying the anti-condensation assembly process for the pipes. Furthermore, the foam layer provides all-around cushioning and support for the refrigeration pipes 3, absorbing vibration and impact during transportation and handling, effectively reducing problems such as bending, weld cracking, and leakage of the refrigeration pipes 3, and improving the reliability of the refrigeration equipment.

[0065] The refrigeration equipment also includes a refrigeration evaporator 6, and the cabinet also forms a refrigeration compartment 12. The refrigeration compartment 12 is located on one side of the freezer compartment 13. The ice-making component 7 is disposed in the refrigeration compartment 12. Both the refrigeration evaporator 6 and the ice-making component 7 are connected to the refrigeration pipeline 3. The refrigerant discharged from the compressor 8 of the refrigeration equipment can selectively flow through the refrigeration evaporator 6, the ice-making component 7, and the freezing evaporator 2 as needed. When the refrigeration compartment 12 needs cooling, the refrigerant flows through the throttling mechanism, the refrigeration evaporator 6, and the freezing evaporator 2 in sequence for heat exchange, and then flows back into the compressor to complete the cooling of the refrigeration compartment 12. When the freezing compartment 13 needs cooling, the refrigerant flows directly through the throttling mechanism to the freezing evaporator 2 for cooling, and finally flows back into the compressor to complete the cooling of the freezing compartment 13. When the refrigeration equipment has an ice-making requirement, the refrigerant flows through the throttling mechanism, the ice-making component 7, and the freezing evaporator 2 in sequence, or it can flow through the throttling mechanism, the ice-making component 7, the refrigeration evaporator 6, and the freezing evaporator 2 in sequence, and finally flows back into the compressor to complete the ice-making requirement.

[0066] In other words, the refrigerant passing through the refrigeration evaporator 6, the refrigerant passing through the ice-making component 7, and the refrigerant directly passing through the throttling mechanism all need to converge before flowing to the evaporator inlet 21. This means that at least two pipes need to be connected in parallel. Existing parallel pipe structures are generally T-shaped, with the two inflow pipes forming the horizontal part of the T. In this structure, during use, the refrigerant flowing in one inflow pipe will be propelled into the other inflow pipe by inertia, causing uncontrollable flow direction within the pipes. This also leads to mutual impact between the two refrigerants, generating severe turbulence and eddies, significantly increasing the fluid flow resistance inside the refrigeration pipes 3, increasing the compressor load and the energy consumption of the refrigeration equipment. Furthermore, the refrigerant impact can cause alternating stress at the pipe connection points, leading to fatigue cracking of welds and refrigerant leakage.

[0067] Therefore, such as Figure 5 As shown, the refrigeration pipeline 3 of this application includes a first connecting pipeline 31 for connecting to the ice-making assembly 7 or the refrigeration evaporator 6, a second connecting pipeline 32 for connecting to the condenser 9, and a manifold 33. The first connecting pipeline 31 and the second connecting pipeline 32 are both connected to the manifold 33, and the acute angle formed between the first connecting pipeline 31 and the manifold 33 is in the range of 15° to 60°. By limiting the angle to 15° to 60°, the refrigerant flowing from the first connecting pipeline 31 into the manifold 33 will flow smoothly into the manifold 33 under the angle limitation, avoiding the problem of refrigerant rushing into the second connecting pipeline 32, reducing the problem of eddy currents and turbulence generated by the refrigerant in the manifold 33, reducing the refrigerant flow resistance, and improving the refrigerant circulation efficiency. Moreover, the acute angle allows the refrigerant to flow smoothly into the manifold 33, reducing the impact on the connection between the first connecting pipe 31 and the manifold 33, preventing the weld joint between the first connecting pipe 31 and the manifold 33 from cracking, and improving the reliability of the refrigerant pipe 3.

[0068] Similarly, the acute angle formed between the second connecting pipe 32 and the manifold 33 ranges from 15° to 60°.

[0069] Preferably, both the first connecting pipe 31 and the second connecting pipe 32 are connected to the end of the manifold 33, at which point the first connecting pipe 31, the second connecting pipe 32, and the manifold 33 form a "Y" shape. This ensures a smooth transition in the flow direction when the refrigerant converges, avoiding eddies and turbulence problems caused by the vertical convergence of pipes, effectively reducing refrigerant flow resistance, improving refrigeration cycle efficiency, and shortening the cooling time for refrigeration, freezing, and ice making.

[0070] Furthermore, such as Figure 3 and Figure 4As shown, the connection point between the first connecting pipe 31 and the manifold 33 is located in the area of ​​the housing 1 away from the opening 11 or within the freezer compartment 13. When the manifold is located in the rear area of ​​the housing 1 away from the opening 11, multiple branch pipes are centrally housed in the back foamed interlayer, facilitating centralized coverage of the anti-condensation structure and making the assembly process centralized and efficient. Furthermore, the connection point between the first connecting pipe 31 and the manifold 33 is far from the welding position between the manifold 33 and the evaporator inlet 21, ensuring that the high temperature during welding does not affect the reliability of the connection point and improving the reliability of the refrigeration equipment.

[0071] Similarly, the connection point between the second connecting pipe 32 and the manifold 33 is located in the area of ​​the housing 1 away from the opening 11 or inside the freezer compartment 13. The connection point between the second connecting pipe 32 and the manifold 33 is far from the welding position between the manifold 33 and the evaporator inlet 21, so the high temperature during the welding process will not affect the reliability of the connection point, thus improving the reliability of the refrigeration equipment.

[0072] Furthermore, by setting the connection points of the first connecting pipe 31, the second connecting pipe 32, and the manifold pipe 33 within the freezer compartment 13, the low-temperature freezer compartment 13 can accommodate the multi-pipe manifold connector. The manifold pipe 33 only needs to extend forward a short distance to the evaporator inlet 21 near the opening 11 for docking, which greatly reduces the area of ​​the exposed low-temperature pipes, effectively suppresses the generation of condensation and water accumulation inside the inner liner 4, and improves the overall reliability of the machine.

[0073] Specifically, the refrigeration equipment also includes a compressor 8, a condenser 9, a refrigeration throttling mechanism 101, and an ice-making throttling mechanism 102. The compressor 8, the condenser 9, the refrigeration throttling mechanism 101, and the refrigeration evaporator 2 constitute a refrigeration cycle, while the compressor 8, the condenser 9, the ice-making throttling mechanism 102, the ice-making assembly 7, the refrigeration evaporator 6, and the refrigeration evaporator 2 constitute an ice-making and refrigeration cycle. The two cycles share the compressor 8 and the condenser 9, reducing the number of core heat exchange components, simplifying the overall piping layout, and lowering equipment material and assembly costs. The refrigeration cycle can independently supply cooling to the refrigeration evaporator to meet the continuous low-temperature storage requirements of the freezer chamber. The ice-making and refrigeration cycle can simultaneously supply refrigerant to the refrigeration evaporator 6 and the ice-making assembly 7, combining refrigeration preservation and ice-making functions. The two operating conditions can be independently controlled without interference, providing greater flexibility in temperature control.

[0074] The refrigerated evaporator 6 and the frozen evaporator 2 are connected by a first connecting pipe 31 and a manifold 33, and the frozen throttling mechanism 101 is connected to the frozen evaporator 2 by a second connecting pipe 32 and a manifold 33.

[0075] Furthermore, the refrigeration equipment also includes an ice removal pipe 103. One end of the ice removal pipe 103 is connected to the condenser 9 or the exhaust port of the compressor 8, and the other end is connected to the ice-making assembly 7. The ice removal pipe 103 can guide the refrigerant that has not flowed through the throttling mechanism into the ice-making assembly 7, thereby heating the ice-making assembly 7 and causing the ice on the ice-making assembly 7 to fall off.

[0076] like Figure 6 and Figure 7 As shown, the de-icing pipe 103 also needs to be connected to the pipe between the ice-making throttling mechanism 102 and the ice-making assembly 7. Therefore, a connection point also needs to be provided. Figure 5 The pipe connection structure shown is designed to prevent high-temperature refrigerant from the de-icing pipe 103 from entering the ice-making throttling mechanism 102, thus preventing the high-temperature refrigerant from damaging the throttling accuracy of the mechanism and avoiding deformation, blockage, or failure of the throttling components due to heat. This is as follows... Figure 5 The acute angle confluence pattern shown can reduce fluid impact caused by the convergence of hot and cold refrigerants, reduce internal pressure pulsation in the pipeline, reduce the risk of leakage at joint welds under long-term alternating loads, and improve the operational stability of the dual circulation system.

[0077] The refrigeration pipe 3 is equipped with an anti-condensation structure. This structure prevents condensation from forming on the refrigeration pipe 3, significantly improving the overall reliability and user experience. Furthermore, since the refrigeration pipe 3 extends into the inner tank 4 to connect with the evaporator 2, the anti-condensation structure eliminates condensation, dripping, and frosting issues, keeping the inner tank 4 dry and clean. This effectively prevents water accumulation, the growth of odors and mold, and electrical malfunctions, thus improving the reliability of the refrigeration equipment.

[0078] The anti-condensation structure can be a return air pipe support structure or thermal insulation foam, thereby preventing the refrigeration pipes inside the foam layer from contacting the back panel 15 of the cabinet and avoiding condensation.

[0079] A water collection tray is installed below the evaporator 2, and the water collection tray is inclined. The inclined water collection tray can promptly collect the defrosting water generated during the operation of the evaporator. The slope formed by the inclined surface of the tray guides the water flow in a specific direction to discharge, avoiding the accumulation of water at the bottom of the evaporator, and further improving the overall operational stability and the cleanliness of the inner tank.

[0080] As one implementation method, such as Figure 8 and Figure 9As shown, the ice-making assembly 7 includes an ice-making container 300, an ice-making evaporator 200, and an ice-storage container 400. The ice-making container 300 is movably disposed within the housing 1. At least a portion of the ice-making evaporator 200 is adapted to extend into the ice-making container 300. The ice-storage container 400 is disposed within the housing 1 and is located below the ice-making evaporator 200 to receive ice blocks on the ice-making evaporator 200. The ice-making evaporator 200 is connected to the refrigeration pipeline 3. When the refrigeration equipment is making ice, the ice-making container 300 moves to a position below the ice-making evaporator 200, and at least a portion of the ice-making evaporator 200 is located within the ice-making container 300. When the refrigeration equipment is de-icing, the ice-making container 300 moves to a clearance position so that the ice blocks on the ice-making evaporator 200 fall into the ice-storage container 400.

[0081] The ice-making evaporator includes a distribution component 210 and a plurality of ice-making columns 220 connected to the distribution component 210. The distribution component 210 is connected to the refrigeration pipeline 3. When the refrigeration equipment makes ice, at least a portion of the ice-making columns 220 can extend into the ice-making container 300.

[0082] When the ice-making component 7 is in the ice-making state, the opening of the ice-making container 300 faces upwards, and a portion of each ice-making column 220 of the ice-making evaporator 200 can be submerged below the liquid surface in the ice-making container 300. Through the evaporation and heat absorption of the flowing refrigerant, the temperature of the surface of the ice-making evaporator 200 drops sharply, causing the water immersed around each ice-making column 220 to freeze rapidly and eventually condense and adhere to each ice-making column 220 to form ice blocks. During the process, the water tank 500 continuously supplies water to the ice-making container 300 through the water circuit assembly. When the water level rises to exceed the maximum capacity of the ice-making container 300, the excess water will overflow from the open side of the ice-making container 300 and fall into the water tank 500 under the action of gravity. In other words, the water tank 500 continuously supplies water to the ice-making container 300 throughout the entire ice-making process. It will not stop supplying water when the ice-making container 300 reaches the maximum water level, so that the water in the ice-making container 300 is always circulating. This circulating water can reduce the generation of air bubbles in the ice.

[0083] The de-icing function is achieved as follows: electrical components drive the ice-making container 300 to rotate. During rotation, the controller of the refrigeration equipment precisely controls the rotational speed of the ice-making container 300's rotating shaft to maintain smooth rotation as much as possible. By driving the ice-making container 300 to rotate, the unfrozen water inside the ice-making container 300 is returned to the water tank 500. When the ice-making component 7 is in the de-icing state, the opening of the ice-making container 300 faces to the side, and the ice-making container 300 does not obstruct the space below the multiple ice-making columns 220. In this way, after the ice-making evaporator 200 is heated, the ice layer adhering between the ice and the corresponding ice-making column 220 melts into a water film, greatly reducing the adhesion force. Thus, the ice originally attached to the ice-making column 220 can be peeled off by its own gravity and fall into the ice storage container 400 below. The user can open the corresponding opening on the cabinet 1 at any time to take out the ice stored in the ice storage container 400.
