[0028] Refer to Figure 3 (The arrows in the figure indicate the flow direction of the cold air), 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 provided in the ice-making evaporation chamber 21. The ice-making refrigeration system 20 is used to supply cold air specifically to the ice-making chamber 14. By providing an ice-making chamber 14 with independent cooling in the storage chamber 13, it is possible to prevent the ice cubes made by the ice maker 30 in the ice-making chamber 14 from being contaminated by the odor and bacteria in the storage chamber 13, and ensure the cleanliness of the ice-making chamber 14.

[0029] Refer to Figures 1 to 3, in this embodiment, there is a spaced-apart space between both the ice-making evaporation chamber 21 and the ice maker 30 and the wall of the ice-making chamber 14. The ice-making evaporation chamber 21 is formed with a first air outlet 24 arranged in cooperation with the ice maker 30, and the cold air in the ice-making evaporator 22 flows through the first air outlet 24 to the ice maker 30, thereby realizing cooling supply to the ice maker 30 and enabling the ice maker 30 to make ice cubes. The ice-making evaporation chamber 21 is further formed with a second air outlet 25 facing the wall of the ice-making chamber 14, and the cold air in the ice-making evaporation chamber 21 flows through the second air outlet 25 to the spaced-apart space between the ice-making evaporation chamber 21 and the ice maker 30 and the wall of the ice-making chamber 14.

[0030] Since the space in the ice-making chamber 14 is limited and the structural arrangement in the ice-making chamber 14 is relatively compact, the ice-making evaporation chamber 21 and the ice maker 30 are often arranged in contact with the wall of the ice-making chamber 14 or too close to the wall of the ice-making chamber 14. By reserving a spaced-apart space between the ice-making evaporation chamber 21 and the wall of the ice-making chamber 14, an air path through which cold air can flow can be formed between the ice-making evaporation chamber 21 and the wall of the ice-making chamber 14, improving the air circulation at the wall of the ice-making chamber 14 and reducing the risk of frosting on the wall of the ice-making chamber 14 and the wall of the ice-making evaporation chamber 21, thus avoiding affecting the ice-making efficiency. Similarly, by reserving a spaced-apart space between the ice maker 30 and the ice-making chamber 14, an air path through which cold air can flow can also be formed between the ice maker 30 and the wall of the ice-making chamber 14, improving the air circulation at the wall of the ice-making chamber 14 and reducing the risk of frosting on the wall of the ice-making chamber 14 and the wall of the ice maker 30, thus avoiding affecting the ice-making efficiency.

[0031] The wall 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] Refer to Figure 3 and Figure 4 (The arrows in the figure indicate the flow direction of the cold air). In an embodiment of the present utility model, the ice-making evaporation chamber 21 is arranged at the top of the ice-making chamber 14. The refrigerator 100 may further include an ice storage box 40 arranged in the ice-making chamber 14. The ice storage box 40 may be arranged below the ice-making evaporation chamber 21 and the ice maker 30. The ice storage box 40 may include a bottom wall and side walls extending upward from the bottom wall. The side walls 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 receive the ice cubes dropped by the ice maker 30.

After the cold air flowing out from the second air outlet 25 flows through the spaced-apart space between the side walls of the ice storage box 40 and the wall of the ice-making chamber 14, it flows to the spaced-apart space between the bottom wall of the ice storage box 40 and the bottom wall 142 of the ice-making chamber 14.

[0033] By reserving a gap space between the side wall of the ice storage box 40 and the side wall of the ice making chamber 14, an air passage through which cold air can flow can be formed between the side wall of the ice storage box 40 and the side wall of the ice making chamber 14, improving the air circulation at the side wall of the ice storage box 40, thereby reducing the risk of frosting at the walls of the ice storage box 40 and the ice making chamber 14. By reserving a gap space between the bottom wall of the ice storage box 40 and the bottom wall 142 of the ice making chamber 14, an air passage through which cold air can flow can be formed between the bottom wall of the ice storage box 40 and the bottom wall 142 of the ice making chamber 14, improving the air circulation, thereby reducing the risk of frosting at the bottom wall 142 of the ice storage box 40 and the ice making chamber 14.

The cold air in the air cavity flows upward above the ice storage box 40 through the air cavity air outlet 42. Both the air cavity air inlet 41 and the air cavity air outlet 42 are located inside the ice making chamber 14. With such a setting, a reasonable air circulation path can be formed. After the cold air flows out from the second air outlet 25 provided at the top of the ice making chamber 14, it first flows through the gap space between the wall of the ice making chamber 14, the ice making evaporation chamber 21 and the ice maker 30, then flows downward through the gap space between the side wall of the ice making chamber 14 and the side wall of the ice storage box 40, then flows along the gap space between the bottom walls of the ice making chamber 14 and the ice storage box 40, and then flows upward through the air cavity at the front part of the ice storage box 40 to the ice making evaporation chamber 21, thereby increasing the air volume in the gap at the wall of the ice making chamber 14, reducing the airless area in the ice making chamber 14, and reducing the frosting risk.

[0049] In summary, for the refrigerator 100 of the present utility model, it can solve the problem that the ice cubes manufactured by the ice maker 30 are easily contaminated by the odor and bacteria in the storage compartment 13, resulting in unclean ice cubes prepared.

[0050] Adopting the technical solution of the present utility model, it is possible to realize an ice-making compartment 14 with independent cooling in the storage compartment 13, which can avoid the ice cubes manufactured by the ice maker 30 in the ice-making compartment 14 from being contaminated by the odor and bacteria in the storage compartment 13, ensure the cleanliness of the ice-making compartment 14, and form a reasonable air circulation path. The cold air in the ice-making evaporation chamber 21 flows out from the rear end of the top of the ice-making compartment 14 through the first air outlet 24, and another part flows out from the second air outlet 25. The cold air flowing out from the first air outlet 24 enters the ice maker through the air duct air inlet 51, flows through the ice mold 32 in a blowing manner from the rear to the front, and ensures the uniformity of the cold air distribution in the air duct 50 through the air distribution plate 53. The 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 in the ice mold 32, improves the heat exchange rate between the cold air and the water in the ice mold 32, shortens the ice-making time. Part of the cold air in the air duct 50 flows out from the front end of the ice maker bracket 31 and flows to the air return port 26. There is also part of the cold air in the air duct 50 flowing through the interval space between the ice maker 30 and the ice-making evaporation chamber 21 from the interval space at the top of the left side wall of the ice maker bracket 31 and then flowing to the air return port 26. There is also part of the cold air in the air duct 50 flowing through the interval space between the ice maker 30 and the right wall of the ice-making compartment 14 from the interval space at the top of the right side wall of the ice maker bracket 31 and then flowing to the air return port 26. In this way, the cold air flowing out from the first air outlet 24 completes the air circulation. The cold air flowing out from the second air outlet 25 flows downward along the interval space at the rear wall 141 of the ice-making compartment 14 to between the side wall of the ice-making compartment and the ice storage box 40, then flows to between the bottom wall of the ice-making box and the ice storage box 40, then flows forward along the bottom wall of the ice storage box 40 from the rear, and then flows upward through the air cavity formed by the front wall of the ice storage box 40 to the periphery of the air return port 26 at the front end of the top of the ice-making compartment 14. Part of the cold air flowing out from the air cavity air outlet 42 is first guided to the space between the ice-making evaporation chamber 21 and the wall of the ice-making compartment through the guiding structure 27 and then flows back to the air return port 26, and the other part directly flows back to the air return port 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 compartment 14 and reducing the frosting risk.
