[0024] The refrigeration equipment of this invention can be a refrigerator 100, a freezer, or a commercial display case, etc. The specific embodiments of this patent will be described below using a refrigerator 100 as an example.

[0025] Reference Figure 1In one embodiment of the present invention, the refrigerator 100 may include a cabinet 1 and a storage compartment 13 formed within the cabinet 1. The refrigerator 100 may further include an ice-making compartment 14 disposed within the storage compartment 13 and an ice-making refrigeration system 20 disposed within the ice-making compartment 14. An opening may be formed on the front side of the ice-making compartment 14. The ice-making refrigeration system 20 may be installed within the ice-making compartment 14 through the opening. An ice maker 30 for making ice cubes may be disposed within the ice-making compartment 14.

[0026] Reference Figure 1 In this embodiment, a partition 15 can be provided inside the storage compartment 13, and an ice-making chamber 14 can be formed by the partition 15 and the side walls of the storage compartment 13. An opening can be formed on the front side of the storage compartment 13. The partition 15 can be installed inside the storage compartment 13 through the opening. Preferably, the partition 15 can form the ice-making chamber 14 by the left, right, and rear walls of the storage compartment 13. The ice-making chamber 14 can be located at the top of the storage compartment 13, and the partition 15 can be opposite to the top wall of the storage compartment 13. The partition 15, the top wall, left, right, and rear walls of the storage compartment 13, and the partition 15 form the bottom wall 142 of the ice-making chamber 14. In other embodiments, the ice-making chamber 14 can also be located at the bottom of the storage compartment 13, and the partition 15 can form the ice-making chamber 14 by the bottom wall, left, right, and rear walls of the storage compartment 13.

[0027] Reference Figures 1 to 3 In this embodiment, the cabinet 1 may include a shell 11 and an inner liner 12. The inner liner 12 may form a storage compartment 13. The refrigerator 100 may also include a cooling cavity 17 for supplying cooling to the storage compartment 13. A storage evaporator may be disposed in the cooling cavity 17. The cooling cavity 17 may be located inside the inner liner 12. Preferably, an air duct 50 cover 16 is disposed inside the inner liner 12. The air duct 50 cover 16 is disposed on the rear side of the storage compartment 13 and forms the rear wall of the storage compartment 13 and the rear wall 141 of the ice-making compartment 14. The air duct 50 cover 16, the rear wall and the side wall of the inner liner 12 enclose the cooling cavity 17. Preferably, the storage compartment 13 is a freezer compartment. In other embodiments, the storage compartment 13 may also be a refrigerator compartment or a variable temperature compartment, etc.

[0028] Reference Figure 3 (The arrows in the diagram indicate the direction of cold air flow.) In this embodiment, the ice-making refrigeration system 20 may include an ice-making evaporation chamber 21, and an ice-making evaporator 22 may be installed inside the ice-making evaporation chamber 21. The ice-making refrigeration system 20 is used to specifically supply cooling to the ice-making chamber 14. By providing an ice-making chamber 14 with independent cooling inside the storage chamber 13, it is possible to prevent the ice produced by the ice maker 30 inside the ice-making chamber 14 from being contaminated by odors and bacteria inside the storage chamber 13, thus ensuring the cleanliness of the ice-making chamber 14.

[0029] Reference Figures 1 to 3In this embodiment, both the ice-making evaporation chamber 21 and the ice maker 30 have a space between them and the wall of the ice-making chamber 14. The ice-making evaporation chamber 21 has a first air outlet 24 that cooperates with the ice maker 30. Cold air in the ice-making evaporator 22 flows to the ice maker 30 through the first air outlet 24, thereby supplying cooling to the ice maker 30 and enabling the ice maker 30 to make ice. The ice-making evaporation chamber 21 also has a second air outlet 25 facing the wall of the ice-making chamber 14. Cold air in the ice-making evaporation chamber 21 flows to the space between the ice-making evaporation chamber 21 and the ice maker 30 and the wall of the ice-making chamber 14 through the second air outlet 25.

[0030] Because the space inside the ice-making chamber 14 is limited, its internal structure is relatively compact. The ice-making evaporation chamber 21 and the ice maker 30 are often positioned close to or excessively close to the walls of the ice-making chamber 14. By leaving a gap between the ice-making evaporation chamber 21 and the walls of the ice-making chamber 14, an airflow path for cold air can be formed between them, improving air circulation at the walls of the ice-making chamber 14 and reducing the risk of frost formation on the walls of the ice-making chamber 14 and the ice-making evaporation chamber 21, thus avoiding any impact on ice-making efficiency. Similarly, by leaving a gap between the ice maker 30 and the ice-making chamber 14, an airflow path for cold air can also be formed between the ice maker 30 and the walls of the ice-making chamber 14, improving air circulation at the walls of the ice-making chamber 14 and reducing the risk of frost formation on the walls of the ice-making chamber 14 and the ice maker 30, thus avoiding any impact on ice-making efficiency.

[0031] The walls of the ice-making chamber 14 may include a bottom wall 142, a top wall, and side walls extending upward relative to the bottom wall 142. Specifically, the side walls of the ice-making chamber 14 may include a front wall, a rear wall 141, a left wall, and a right wall.

[0032] Reference Figure 3 and Figure 4 (The arrows in the diagram indicate the direction of cold air flow.) In one embodiment of the present invention, the ice-making evaporation chamber 21 is disposed at the top of the ice-making chamber 14. The refrigerator 100 may also include an ice storage box 40 disposed within the ice-making chamber 14. The ice storage box 40 may be disposed below the ice-making evaporation chamber 21 and the ice maker 30. The ice storage box 40 may include a bottom wall and a side wall extending upward from the bottom wall. The side wall of the ice storage box 40 may include front and rear side walls and left and right side walls. The upper end of the ice storage box 40 may be open to collect ice blocks falling from the ice maker 30. There is a space between the side wall of the ice storage box 40 and the wall of the ice-making chamber 14, and there is a space between the bottom wall of the ice storage box 40 and the bottom wall 142 of the ice-making chamber 14. The cold air flowing out of the second air outlet 25 flows through the space between the side wall of the ice storage box 40 and the wall of the ice-making chamber 14, and then flows into the space between the bottom wall of the ice storage box 40 and the bottom wall 142 of the ice-making chamber 14.

[0033] By providing a gap between the side walls of the ice storage box 40 and the side walls of the ice-making chamber 14, an airflow path for cold air can be formed between these two locations, improving air circulation and reducing the risk of frost formation on the walls of the ice storage box 40 and the ice-making chamber 14. Similarly, by providing a gap between the bottom wall of the ice storage box 40 and the bottom wall 142 of the ice-making chamber 14, an airflow path for cold air can be formed between these two locations, improving air circulation and reducing the risk of frost formation on the bottom wall of the ice storage box 40 and the ice-making chamber 14.

[0034] Reference Figures 3 to 5 In one embodiment of the present invention, an air cavity is formed inside the front wall of the ice storage box 40. The air cavity may include an air cavity inlet 41 located at the bottom of the ice storage box 40 and an air cavity outlet 42 located at the top of the ice storage box 40. Cold air in the space between the bottom wall of the ice storage box 40 and the bottom wall 142 of the ice-making chamber 14 enters the air cavity through the air cavity inlet 41. The cold air in the air cavity flows upwards from the ice storage box 40 through the air cavity outlet 42. Both the air cavity inlet 41 and the air cavity outlet 42 are located inside the ice-making chamber 14. This configuration creates a reasonable air circulation path. After the cold air flows out from the second air outlet 25 located at the top of the ice-making chamber 14, it first flows through the gap between the wall of the ice-making chamber 14, the ice-making evaporation chamber 21, and the ice maker 30. Then, it flows downward through the gap between the side wall of the ice-making chamber 14 and the side wall of the ice storage box 40. Then, it flows along the gap between the bottom wall of the ice-making chamber 14 and the ice storage box 40. Finally, it flows upward through the air cavity at the front of the ice storage box 40 towards the ice-making evaporation chamber 21. This increases the airflow in the gaps at the wall of the ice-making chamber 14, reduces the windless areas in the ice-making chamber 14, and lowers the risk of frost formation.

[0035] Reference Figure 3 and Figure 4 In one embodiment of the present invention, the second air outlet 25 is located at the rear end of the ice-making evaporation chamber 21 and faces the rear wall 141 of the ice-making chamber 14. There is a space between the rear wall 141 of the ice-making chamber 14 and the rear walls of the ice-making evaporation chamber 21, the ice maker 30, and the ice storage box 40. The cold air flowing out of the second air outlet 25 first passes through the space between the rear wall 141 of the ice-making chamber 14 and the ice-making evaporation chamber 21 and the ice maker 30, then through the space between the rear wall 141 of the ice-making chamber 14 and the rear wall of the ice storage box 40, and then through the space between the bottom wall of the ice storage box 40 and the bottom wall 142 of the ice-making chamber 14, flowing from back to front into the air cavity.

[0036] Reference Figure 1 and Figure 3In one embodiment of the present invention, there is a gap between the left / right side walls of the ice-making evaporation chamber 21 and the left / right side walls of the ice-making chamber 14. An air guide structure 27 is provided on the front wall of the ice-making evaporation chamber 21, located above the air outlet 42 of the air chamber. The air guide structure 27 is used to guide at least a portion of the cold air flowing from the air outlet 42 of the air chamber to the gap between the left / right side walls of the ice-making evaporation chamber 21 and the ice-making chamber 14. By reserving a gap between the left / right side walls of the ice-making evaporation chamber 21 and the left / right side walls of the ice-making chamber 14, and by guiding the cold air to the gap between the left / right side walls of the ice-making chamber 14 through the air guide structure 27, an airflow path for cold air can be formed between the left / right side walls of the ice-making evaporation chamber 21 and the left / right side walls of the ice-making chamber 14, improving air circulation at the left / right side walls of the ice-making chamber 14, thereby reducing the risk of frost formation at the left / right side walls of the ice-making chamber 14.

[0037] In another embodiment of the present invention, the second air outlet can be located at the left / right end of the ice-making evaporation chamber 21 and facing the left / right wall of the ice-making chamber 14. There is a space between the left / right wall of the ice-making chamber 14 and the ice-making evaporation chamber 21, the ice maker 30, and the ice storage box 40. The cold air flowing out of the second air outlet flows through the space between the left / right wall of the ice-making chamber 14 and the ice-making evaporation chamber 21, the ice maker 30, and the ice storage box 40 to the space between the bottom wall of the ice storage box 40 and the bottom wall of the ice-making chamber 14. In other embodiments of the present invention, multiple second air outlets can be provided. The left / right side walls and the rear wall of the ice-making evaporation chamber 21 can both be provided with second air outlets so that the cold air flowing out of the second air outlets can flow from the space between the rear wall and the left / right side walls of the ice-making chamber 14 to the space between the bottom wall of the ice-making chamber 14.

[0038] Reference Figure 1 and Figure 3 In one embodiment of the present invention, the ice-making evaporation chamber 21 and the ice maker 30 are arranged side by side along the left and right width direction of the ice-making chamber 14. A return air vent 26 is provided on the front wall of the ice-making evaporation chamber 21. The return air vent 26 is located above the air guide structure 27, and at least a portion of the return air vent 26 is located on the ice maker 30 side of the air guide structure 27. At least a portion of the cold air flowing from the air outlet 42 of the air cavity flows from the ice maker 30 side of the air guide structure 27 to the return air vent 26. In one embodiment of the present invention, the air guide structure 27 may include a first air guide rib 271 extending upward from the lower end of the front wall of the ice-making evaporation chamber 21, and the air guide structure 27 may also include a second air guide rib 272 extending from the upper end of the first air guide rib 271 to the left / right end of the front wall of the ice-making evaporation chamber 21.

[0039] Reference Figure 3 and Figure 4Preferably, the ice-making evaporation chamber 21 is located on the left side of the ice maker 30, and part of the return air vent 26 is located on the right side of the air guide structure 27. The second air guide rib 272 extends from the upper end of the first air guide rib 271 to the left end of the front wall of the ice-making evaporation chamber 21. Part of the cold air flowing out of the air cavity outlet 42 flows directly from the right side of the air guide structure 27 to the return air vent 26, and part is guided by the air guide structure 27 to the space between the ice-making chamber 14 and the left wall of the ice-making evaporation chamber 21. There are several air cavity inlets 41 arranged side by side in the horizontal direction. Air cavity inlets 41 are distributed on the left, right and middle parts of the front wall of the ice storage box 40. There are several air cavity outlets 42 arranged side by side in the horizontal direction. Air cavity inlets 41 are distributed on the left and middle parts of the front wall of the ice storage box 40.

[0040] Reference Figure 2 , Figure 3 and Figure 6 In one embodiment of the present invention, the ice maker 30 may include an ice maker support 31 and an ice mold 32 mounted on the ice maker support 31. The upper end of the ice maker support 31 is open. The refrigeration chamber equipment may also include a mounting bracket 60 disposed above the ice maker support 31. The mounting bracket 60 covers the upper end of the ice maker support 31 and surrounds the ice maker support 31 to form an air duct 50. The air duct 50 may include an air duct inlet 51 opposite to the first air outlet 24. The air duct inlet 51 is located on the side of the ice evaporation chamber 21 at the rear end of the ice maker support 31. The cold air entering through the air duct inlet 51 flows from back to front along the air duct 50 through the ice mold 32.

[0041] Reference Figure 3 In one embodiment of the present invention, an air guide plate 52 is provided on the upper end of the ice maker bracket 31. The air guide plate 52 is located above the ice mold 32 and its downward projection covers the rear part of the ice mold 32. The air guide plate 52 extends downward from back to front to guide the cold air in the rear air duct 50 to flow downward to the ice mold 32.

[0042] Reference Figure 3 In one embodiment of the present invention, the ice maker support 31 has an air distribution plate 53 longitudinally disposed within the air duct 50, the air distribution plate 53 being located between the air guide plate 52 and the air inlet 51 of the air duct. There are a plurality of air distribution plates 53 disposed at intervals, the lower end of the ice maker support 31 has an opening, and the ice mold 32 closes the lower end opening of the ice maker support 31.

[0043] Reference Figure 3Preferably, the first air outlet 24 is located on the right side of the rear end of the ice-making evaporation chamber 21, and the air inlet 51 is located on the left side of the rear end of the ice maker 30 and opposite to the first air outlet 24. The air inlet 51 is located behind the ice mold 32. The cold air coming out from the side of the ice-making evaporation chamber 21 flows through the air duct 50 in a back-to-forehead blowing manner through the ice mold 32. The air distribution plate 53 can ensure that the cold air distribution is more uniform. The air guide plate 52 can form a downward cold air flow path so that the cold air is horizontally close to the upper surface of the water in the ice mold 32, thereby improving the heat exchange rate between the cold air and the water in the ice mold 32 and shortening the ice-making time.

[0044] In one embodiment of the present invention, an air duct outlet can be formed at the front end of the ice maker support 31, so that the cold air in the air duct 50 can flow out from the front end of the ice maker support 31 and flow to the return air vent 26 at the front end of the ice evaporation chamber 21, so as to facilitate air circulation.

[0045] Reference Figure 3 In one embodiment of the present invention, a gap space may be reserved between the top of the left and right side walls of the ice maker bracket 31 and the mounting bracket 60, a gap space may be reserved between the ice maker 30 and the ice-making evaporation chamber 21, and a gap space may be reserved between the ice maker 30 and the right wall of the ice-making chamber 14. This arrangement allows some of the cold air in the air duct 50 to flow through the gap space at the top of the left side wall of the ice maker bracket 31 to the gap space between the ice maker 30 and the ice-making evaporation chamber 21, improving air circulation between the ice maker 30 and the ice-making evaporation chamber 21. Similarly, some of the cold air in the air duct 50 may flow through the gap space at the top of the right side wall of the ice maker bracket 31 to the gap space between the ice maker 30 and the right wall of the ice-making chamber 14, improving air circulation between the ice maker 30 and the right wall of the ice-making chamber 14 and reducing the risk of frost formation.

The cold air entering the ice-making evaporation chamber 21 from the return air inlet 26 first flows through the ice-making evaporator 22 and undergoes sufficient heat exchange with it, then flows to the fan 23, and is driven by the fan 23 to flow out from the first air outlet 24 and the second air outlet 25.

[0048] Reference Figures 1 to 3 In one embodiment of the present invention, the ice-making and refrigeration system 20 may include a housing integration module, which may include an upper housing 281, a lower housing 282, an ice-making evaporator 22 installed on the upper housing 281, and a fan 23 installed on the lower housing 282. The housing integration module is mounted on a mounting bracket 60. This configuration facilitates the modular design of the ice-making and refrigeration system 20, making it easier to operate and install quickly and conveniently.

[0049] In summary, the refrigerator 100 of the present invention can solve the problem that ice cubes produced by the ice maker 30 are easily contaminated by odors and bacteria in the storage compartment 13, resulting in unclean ice cubes.

[0050] By adopting the technical solution of the present invention, an ice-making chamber 14 with independent cooling can be set up in the storage chamber 13. This can prevent the ice produced by the ice maker 30 in the ice-making chamber 14 from being contaminated by odors and bacteria in the storage chamber 13, ensuring the cleanliness of the ice-making chamber 14. A reasonable air circulation path can be formed. The cold air in the ice-making evaporation chamber 21 flows out from the top rear end of the ice-making chamber 14 through the first air outlet 24 and also flows out through the second air outlet 25. The cold air flowing out from the first air outlet 24 enters the ice-making chamber through the air inlet 51 of the air duct. Inside the machine, the airflow flows from back to front through the ice mold 32, and the air distribution plate 53 ensures the uniformity of the cold air distribution within the air duct 50. The air guide plate 52 forms a downward-pressing cold air flow path, so that the cold air is horizontally close to the upper surface of the water inside the ice mold 32, improving the heat exchange rate between the cold air and the water inside the ice mold 32 and shortening the ice-making time. Some of the cold air in the air duct 50 flows out from the front end of the ice maker support 31 and flows to the return air vent 26. Some of the cold air in the air duct 50 also flows through the ice maker 30 from the gap space at the top of the left side wall of the ice maker support 31. After passing through the space between the ice-making evaporation chamber 21 and the evaporation chamber 21, the cold air flows to the return air vent 26. Some cold air within the duct 50 also flows from the space at the top right side wall of the ice maker support 31, through the space between the ice maker 30 and the right wall of the ice-making chamber 14, and then to the return air vent 26. Thus, the cold air flowing from the first air outlet 24 completes the air circulation. The cold air flowing from the second air outlet 25 flows downwards along the space at the rear wall 141 of the ice-making chamber 14 to the space between the side wall of the ice-making chamber 14 and the ice storage box 40, and then flows to the bottom wall between the ice-making box and the ice storage box 40. The cold air flows from back to front along the bottom wall of the ice storage box 40, and then from bottom to top through the air cavity formed by the front wall of the ice storage box 40 to the area around the return air vent 26 at the top front of the ice making chamber 14. Part of the cold air flowing out of the air cavity outlet 42 is guided by the air guide structure 27 to the space between the ice making evaporation chamber 21 and the wall of the ice making chamber 14 and then flows back to the return air vent 26. The other part flows directly back to the return air vent 26. In this way, the cold air flowing out from the second air outlet 25 completes the air circulation, thereby reducing the windless area in the ice making chamber 14 and reducing the risk of frost formation.
