CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to Chinese Utility Model Patent Application No. CN 202420335308.0, filed on Feb. 22, 2024, published as CN 222230984 U on Dec. 24, 2024, and entitled “An ice making machine and a refrigerator,” the entire disclosure of which is hereby incorporated by reference.TECHNICAL FIELD
[0002] The present disclosure relates to the technical field of refrigerators, and more specifically relates to an ice making machine and a refrigerator.BACKGROUND
[0003] With the continuous improvement of living standards, refrigerators have become an important appliance. Refrigerators use refrigeration to maintain an interior cabinet at a low temperature, which is beneficial to preserve food. Refrigerators can also make ice by setting up a simple ice-making device, which is extremely convenient and can meet a users' demand for ice cubes. However, existing refrigerator ice makers still have several defects. For example, when assembling the ice making machine used in traditional refrigerators, the assembly method is complicated, which makes it difficult to assemble. Also, in traditional refrigerators, air inlets of the ice machine may be designed to be flush with the surface of the ice tray, which allows cold air to flow horizontally across the surface of the ice tray. Since the level of the ice-making surface is lower than the surface of the ice tray, and the cold air flows horizontally, eddy currents will appear in the ice tray close to the air outlet, which results in insufficient heat exchange and a longer freezing time for the ice cubes.
[0004] Compared with existing technology, the present disclosure realizes the rapid assembly of the frame and the box of the ice machine through simple assembly components. Through the setting of the inclined baffle at the air outlet of the induced air duct, it solves the problem of long freezing time of ice caused by insufficient heat exchange problem, thus shortening the ice making cycle.SUMMARY
[0005] According to an aspect of the present disclosure, an ice making machine includes an ice making machine frame that is provided with an ice-making tray assembly that has multiple ice trays. An ice-turning motor is fixedly connected to one end of the ice tray and is used to drive the ice tray to turn over. An induced air duct includes an air inlet and an air outlet. The air outlet is provided with a sloped baffle. The sloped baffle is arranged at an angle and is perpendicular to a surface of the ice tray along a cold air flow direction, in the direction gradually closer to the ice tray.
[0006] According to another aspect of the present disclosure, an ice-making machine includes an ice-making tray assembly that has multiple ice trays. An ice-turning motor is fixedly connected to one end of the ice-making tray assembly. The ice-turning motor is used to drive the ice-making tray assembly to turn. The ice-making machine also includes an induced air duct that an air inlet and an air outlet and an ice-making machine frame that has an ice detection rod. The air outlet includes an inclined baffle arranged at an angle along the cold air flow direction. The inclined baffle gradually approaches the ice-making tray assembly in a direction perpendicular to a horizontal surface of the ice-making tray assembly. The ice detection rod is installed on the ice-turning motor and the ice-making machine frame is installed in a box of a freezing chamber of a refrigerator. Assembly components are distributed on a contact surface between the ice-maker frame and the box to fix the ice-maker frame to the box. The assembly components include a clamping slot, a fixed hanging column, and an elastic limiter.
[0007] According to another aspect of the present disclosure, an ice-making machine includes an ice-making tray assembly that has multiple ice trays. An ice-turning motor is fixedly connected to one end of the ice-making tray assembly. The ice-turning motor is used to drive the ice-making tray assembly to turn. The ice-making machine also includes an air duct that has an air inlet and an air outlet. The air outlet has an inclined baffle arranged at an angle along the cold air flow direction. The inclined baffle gradually approaches the ice-making tray assembly at an acute angle relative to a horizontal surface of the ice making tray assembly.BRIEF DESCRIPTION OF THE DRAWINGS

The ice-making tray assembly 21 may be fixedly coupled with the ice making machine frame 20 and the other end may be fixedly coupled with the ice-turning motor 22.
[0021] The ice-turning motor 22 is installed on the ice-making machine frame 20 together with the ice-making tray assembly 21. The ice-turning motor 22 is fixed through two holes by elastic features on the ice-making machine frame 20. The ice turning motor 22 may be energized to drive the ice-making tray assembly 21 to rotate or swing, causing ice cubes in the ice tray 211 to fall. An ice detecting rod 23 is installed on the ice turning motor 22. The ice detecting rod 23 is configured to detect the formation of ice cubes.
[0022] With reference now to FIG. 4, an air duct 24 has an air inlet 241 located on a side of the ice-making tray assembly 21 and an air outlet 242. Cold air flows from bottom to top in a vertical direction of the ice making machine frame 20. The air outlet 242 is provided with an inclined baffle 2421. The inclined baffle 2421 is arranged in an angled or inclined manner and gradually approaches the ice-making tray assembly 21 along the direction of cold air flow. The inclined baffle 2421 is used to prevent at least a portion of the cold air from flowing along the surface of the ice tray 211. While flowing horizontally, another portion of the cold air is guided to flow obliquely toward the ice tray 211 close to the induced draft duct 24. The inclined baffle 2421 is provided to solve the problem of eddy currents that can develop close to the air outlet 242 in traditional ice machines, which in turn causes insufficient heat exchange and a long freezing time for the ice cubes. The inclined baffle 2421 is inclined from top to bottom along the cold air flow direction and may approach a horizontal surface of the ice-making tray assembly 21 at an acute angle. The angle range with the horizontal surface is between 20° and 60°. In some instances, the inclined baffle 2421 may gradually approach the horizontal surface of the ice-making tray assembly 21 at a perpendicular angle relative to the horizontal surface. A distance between the lowest point of the inclined baffle 2421 and the horizontal surface of the ice-making tray assembly 21 ranges from 3 cm to 9 cm.

As shown in FIGS. 4 and 5, the assembly components 25 include a slot 251, a fixed hanging post 252, and an elastic stopper 253. In some instances, the slot 251 has a U-shaped opening. Further, the slots 251 may be evenly distributed at the edge of the contact surface between the ice machine frame 20 and the box 11. The contact surface between the box 11 and the ice machine frame 20 is provided with fixing holes for engaging the slots 251. The fixed hanging post 252 is pushed horizontally into the slot 251 along the inward direction of the opening of the slot 251 to fix the ice maker frame 20 and the box 11. The fixed hanging post 252 has a T-shaped structure, the outer surface of the extending end in the vertical direction has a concave-convex structure, and the concave portion of the fixed hanging post 252 engages with the slot 251. The elastic stopper 253 is disposed at the opening of the slot 251 and is tilted into the slot 251 to resist the fixed hanging post 252. The configuration of the assembly components 25 has a simple structure and reduces the installation process of the ice maker and the refrigerator box 11.
