Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to a refrigerator. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature; it is also a consumer product that keeps food or other items at a constant low temperature. Current refrigerators are equipped with ice-making devices to produce ice and meet users' needs for ice.

[0003] The ice-making device of a conventional refrigerator generally includes a water tank, a water pump, a water guiding mechanism, and an ice maker connected in sequence. The water tank and water pump are located in the refrigerator compartment, and the ice maker is located in the freezer compartment. The water guiding mechanism connects the water pump and the ice maker to transport water from the water tank to the ice maker. The water in the ice maker is frozen by the cold air in the freezer compartment to make ice blocks.

[0004] However, because the water supplied to the ice maker contains dissolved air, which cannot dissolve in ice, the air in the water forms bubbles when the water turns into ice, making the ice white and cloudy. Utility Model Content

[0005] This application provides a refrigerator that can reduce air bubbles in ice, thereby making the ice cubes more transparent and improving the user experience.

[0006] In a first aspect, embodiments of this application provide a refrigerator, comprising:

[0007] The enclosure has a low-temperature storage compartment and a cold air aisle.

[0008] Ice-making equipment, located in a low-temperature storage room;

[0009] The ice-making device includes:

[0010] An ice-making tray has a cavity and an opening on its upper surface that communicates with the cavity for filling the cavity with water.

[0011] The air guiding mechanism is connected to the cold air passage and includes:

[0012] The first air vent is configured to face the upper surface of the ice-making tray;

[0013] The second air vent is configured to face the lower surface of the ice-making tray;

[0014] A damper assembly is located between the first air outlet and the second air outlet and the cold air passage, and is configured to control the connection and closure of the first air outlet and the second air outlet with the cold air passage.

[0015] In this way, an air guiding mechanism is connected to the cold air channel, giving the mechanism a first and a second air outlet. The connection and closure of the first and second air outlets with the cold air channel are controlled by a damper assembly, allowing the flow of cold air to be adjusted as needed. This provides greater flexibility and controllability, and can be optimized for different environmental conditions or ice-making requirements. When transparent ice is needed, the second air outlet can be connected to the cold air channel, while the first air outlet is closed. This controls the flow of cold air, causing it to flow over the lower surface of the ice-making pan, accelerating the cooling of the water below. This results in the upper surface of the water being hotter than other surfaces, freezing more slowly. Air dissolved from the remaining water in the ice-making pan can be released into the atmosphere from the upper surface, effectively reducing the formation of air bubbles during ice formation and increasing the transparency of the ice. Transparent ice is more visually appealing, enhancing the overall visual effect and thus improving the overall user experience. Meanwhile, during defrosting, the first and second air vents can be closed by controlling the damper assembly, thereby suppressing the temperature rise in the ice-making device.

[0016] In some embodiments of this application, the gas guiding mechanism further includes:

[0017] The first air guide is located on the wall of the low-temperature storage chamber. The first end of the first air guide is opposite to the cold air passage, and the second end of the first air guide is the first air outlet.

[0018] The second air guide is located on the wall of the low-temperature storage chamber. The first end of the second air guide is opposite to the cold air passage, and the second end of the second air guide is the second air outlet.

[0019] The damper assembly is located between the first end of the first air guide and the first end of the second air guide and the cold air passage.

[0020] In this way, the first and second air guides are connected to different air vents, allowing cold air to be directed to the upper and lower surfaces of the ice-making tray as needed. This flexibility allows for adjustments based on different ice-making requirements to achieve optimal ice-making results. Simultaneously, the design of the first and second air guides enables cold air to reach the upper and lower surfaces of the ice-making tray more directly, reducing cold air loss during transmission and thus improving refrigeration efficiency. The modular design of the first and second air guides makes equipment maintenance and upgrades easier and reduces maintenance costs.

[0021] In some embodiments of this application, the damper assembly includes:

[0022] The first air damper is located between the first end of the first air guide and the cold air passage;

[0023] The second air damper is located between the first end of the second air guide and the cold air passage.

[0024] A drive unit is located between the first damper and the second damper, and is configured to control the opening and closing of the first damper and the second damper.

[0025] In this way, the first and second dampers control the cold air flow of the first and second air guides, respectively, and their opening and closing are precisely controlled by the drive mechanism. This independent control allows the cooling intensity of the upper and lower surfaces of the ice-making tray to be adjusted according to specific ice-making needs, thereby optimizing the ice-making effect. Precise adjustment of the drive mechanism helps maintain optimal cooling efficiency and ice quality under different operating conditions. Furthermore, the control of the drive mechanism allows the dampers to be opened only when needed, reducing unnecessary cold air flow and thus lowering energy consumption.

[0026] In some embodiments of this application, the first damper includes:

[0027] The first air duct connects the first end of the first air guide to the cold air passage.

[0028] The first baffle is rotatably disposed in the first air duct;

[0029] A drive unit is connected to the first air duct, and the drive end is connected to the first baffle and is configured to drive the first baffle to rotate in order to open or close the first air duct.

[0030] This rotatable design of the first baffle allows the drive unit to precisely control the opening of the first air duct, thereby optimizing the cold air flow and achieving a highly efficient ice-making process. Precise control of the opening and closing of the first air duct also reduces unnecessary cold air flow, thus lowering energy consumption. The drive unit can respond to the system's control signals and quickly adjust the angle of the first baffle, ensuring timely system adjustments and improving the efficiency and reliability of the ice-making process.

[0031] In some embodiments of this application, the second damper includes:

[0032] The second air duct connects the first end of the second air guide to the cold air passage.

[0033] The second baffle is rotatably disposed in the second air duct;

[0034] A drive unit is connected to the second air duct, and the drive end is connected to the second baffle and is configured to drive the second baffle to rotate in order to open or close the second air duct.

[0035] This rotatable design of the second baffle allows the drive unit to precisely control the opening of the second air duct, thereby optimizing the cold air flow and achieving a highly efficient ice-making process. Precise control of the second air duct's opening and closing also reduces unnecessary cold air flow, thus lowering energy consumption. The drive unit can respond to the system's control signals and quickly adjust the angle of the second baffle, ensuring timely system adjustments and improving the efficiency and reliability of the ice-making process.

[0036] In some embodiments of this application, the first damper and / or the second damper are dampers.

[0037] In this way, the damper can precisely regulate airflow. By adjusting the damper's opening, precise control of the cold air flow can be achieved, thereby optimizing the ice-making process. Simultaneously, the damper can smoothly regulate airflow, reducing noise generated during airflow and providing a quieter operating environment. The damper can also buffer and regulate changes in airflow, reducing pressure fluctuations within the system, thus helping to protect other components and extend the equipment's lifespan.

[0038] In some embodiments of this application, the second air guide includes:

[0039] The air intake is located on the wall of the low-temperature storage compartment, and the opening of the air intake is opposite to the cold air passage. The air intake extends along the height of the refrigerator.

[0040] The air vent is opposite to the lower surface of the ice-making tray;

[0041] The connecting part connects the air intake and the air outlet.

[0042] In this design, the air intake opening directly faces the cold air passage, allowing cold air to directly enter the second air guide component. This ensures effective guidance of the cold air, reduces losses during airflow, and improves cooling efficiency. The connecting section transports cold air from the air intake to the air outlet, directly acting on the lower surface of the ice maker, ensuring uniform cooling of the bottom of the ice maker. This uniform cooling helps reduce air bubbles and impurities in the ice, improving its transparency and quality. The air intake's extension along the height of the refrigerator ensures that cold air reaches the lower surface of the ice maker quickly and directly, reducing losses during airflow and improving cooling efficiency.

[0043] In some embodiments of this application, the air outlet is provided with an air guiding surface, which is inclined toward the lower surface of the ice-making tray along the direction of cold air delivery.

[0044] In this way, the inclined air guide surface can effectively guide the cold air flowing out of the air outlet, reduce the airflow resistance at the air outlet, and allow the cold air to act directly on the lower surface of the ice-making tray, which helps to improve cooling efficiency, makes the cold air act more concentrated on the ice-making tray, and speeds up the ice-making speed.

[0045] In some embodiments of this application, the air outlet is provided with a second reinforcing plate.

[0046] In this way, the second reinforcing plate increases the structural strength and stability of the air outlet, preventing deformation or damage caused by pressure changes or other external forces during cold air flow. The second reinforcing plate also helps reduce vibrations caused by airflow, thereby reducing noise. Furthermore, the second reinforcing plate helps guide and evenly distribute airflow, ensuring that cold air covers the lower surface of the ice tray more evenly and effectively.

[0047] In some embodiments of this application, the first air guide is provided with a first reinforcing plate.

[0048] In this way, the first reinforcing plate increases the structural strength and stability of the first air guide component, preventing deformation or damage caused by pressure changes or other external forces during cold air flow. The first reinforcing plate also helps reduce vibrations caused by airflow, thereby reducing noise. Furthermore, the first reinforcing plate helps guide and evenly distribute airflow, ensuring that cold air covers the upper surface of the ice-making tray more evenly and effectively.

[0069] A refrigerator is a refrigeration device that maintains a constant low temperature; it is also a consumer product that keeps food or other items at a constant low temperature. Current refrigerators are equipped with ice-making devices to produce ice and meet users' needs for ice.

[0070] The ice-making device of a conventional refrigerator generally includes a water tank, a water pump, a water guiding mechanism, and an ice maker connected in sequence. The water tank and water pump are located in the refrigerator compartment, and the ice maker is located in the freezer compartment. The water guiding mechanism connects the water pump and the ice maker to transport water from the water tank to the ice maker. The water in the ice maker is frozen by the cold air in the freezer compartment to make ice blocks.

[0071] However, because the water supplied to the ice maker contains dissolved air, which cannot dissolve in ice, the air in the water forms bubbles when the water turns into ice, making the ice white and cloudy.

[0072] After repeated consideration and verification, the inventors discovered that by installing a damper between the ice maker and the cold air channel to control the flow of cold air, allowing the cold air to blow across both the top and bottom surfaces of the ice maker, and preventing the cold air from flowing towards the top surface of the ice maker when increasing the transparency of the ice, the cold air is forced to flow across the bottom surface of the ice tray. This suppresses cooling at the top of the ice tray, causing the top surface to freeze more slowly than other surfaces. Air dissolved in other parts of the water in the ice tray can be released into the atmosphere from the top surface of the water, effectively reducing the generation of air bubbles during ice formation and improving the transparency of the ice.

[0073] Figure 1 This is one of the structural schematic diagrams of a refrigerator provided in an embodiment of this application. Figure 2 This is a second schematic diagram of the structure of a refrigerator provided in an embodiment of this application.

[0074] like Figure 1 and Figure 2 As shown, the refrigerator 200 provided in this embodiment includes a cabinet 201. The cabinet 201 has a low-temperature storage compartment 202. The low-temperature storage compartment 202 is used by the user to place food that needs to be refrigerated.

[0075] The refrigerator 200 provided in this embodiment also includes an ice-making device 100. The ice-making device 100 is disposed in the low-temperature storage compartment 202. The ice-making device 100 is used to make ice cubes.

[0076] The housing 201 is equipped with a cold air passage. The cold air passage is used to provide cooling to the ice-making device 100, thereby facilitating the ice-making device 100 to make ice.

[0077] The ice-making device 100 includes an ice maker 10 and a gas guiding mechanism 20. The ice maker 10 is located in a low-temperature storage chamber 202. The gas guiding mechanism 20 is connected to a cold air passage. The gas guiding mechanism 20 is used to guide the cold air in the cold air passage to the ice maker 10, thereby forming ice cubes in the ice maker 10.

[0078] Please also refer to Figure 7 and Figure 9The ice maker 10 includes an ice-making tray 12. The ice-making tray 12 has a cavity, and an opening is provided on the upper surface of the ice-making tray 12, which communicates with the cavity for injecting water into the cavity of the ice-making tray 12, thereby forming ice blocks under the action of cold air.

[0079] Figure 3 for Figure 1 The diagram shows the structure of the air guiding mechanism of the ice-making device in the refrigerator.

[0080] Please also refer to Figure 3 The air guiding mechanism 20 includes a first air vent 21 and a second air vent 22. The first air vent 21 is configured to face the upper surface of the ice-making tray 12. The second air vent 22 is configured to face the lower surface of the ice-making tray 12. The first air vent 21 is used to provide cooling to the upper surface of the ice-making tray 12, and the second air vent 22 is used to provide cooling to the lower surface of the ice-making tray 12.

[0081] Please also refer to Figure 6 The air guiding mechanism 20 also includes a damper assembly 40. The damper assembly 40 is disposed on the cold air passage and located between the first air outlet 21 and the second air outlet 22 and the cold air passage. The damper assembly 40 is configured to control the connection and closure of the first air outlet 21 and the second air outlet 22 with the cold air passage.

[0082] During normal ice making, the damper assembly 40 controls the first air vent 21 and the second air vent 22 to be connected to the cold air passage. The cold air in the cold air passage flows over the upper and lower surfaces of the ice making tray 12, rapidly cooling the water in the ice making tray 12 and freezing it into ice cubes.

[0083] When transparent ice needs to be made, the damper assembly 40 controls the second air vent 22 to connect with the cold air passage and controls the first air vent 21 to close with the cold air passage, thereby controlling the flow of cold air. This allows cold air to flow over the lower surface of the ice-making pan 12, accelerating the cooling of the water below the water in the ice-making pan 12. This makes the temperature of the upper surface higher than that of other surfaces, and the upper surface of the water freezes more slowly than other surfaces. The air dissolved in other parts of the water in the ice-making pan 12 can be released from the upper surface of the water into the atmosphere, thereby effectively reducing the generation of air bubbles during the ice formation process, improving the transparency of the ice, and producing transparent ice.

[0084] During defrosting, the damper assembly 40 controls the closure of the first air vent 21 and the second air vent 22 to prevent ambient or high-temperature gas in the cold air passage from being blown into the ice-making tray 12, thereby suppressing the temperature rise in the ice-making device 100.

[0085] By connecting the air guiding mechanism 20 to the cold air duct, the air guiding mechanism 20 has a first air outlet 21 and a second air outlet 22. The air damper assembly 40 controls the connection and closure of the first air outlet 21 and the second air outlet 22 with the cold air duct, so that the flow of cold air can be adjusted as needed, providing greater flexibility and controllability, and can be optimized according to different environmental conditions or ice-making needs.

[0086] Figure 4 for Figure 3 A schematic diagram of the structure of the first air guide component of the air guide mechanism shown. Figure 5 for Figure 3 A schematic diagram of the structure of the second air guide component of the air guide mechanism shown. Figure 6 for Figure 3 The diagram shows the structure of the damper assembly of the air guiding mechanism.

[0087] Please also refer to Figure 4 and Figure 5 In some embodiments of this application, the air guiding mechanism 20 further includes an air guiding assembly 30, which is disposed on the wall of the low-temperature storage chamber 202. The air guiding assembly 30 includes a first air guiding member 31 and a second air guiding member 32. The first end of the first air guiding member 31 is opposite to the cold air passage, and the second end of the first air guiding member 31 is a first air outlet 21. The first end of the second air guiding member 32 is opposite to the cold air passage, and the second end of the second air guiding member 32 is a second air outlet 22.

[0088] A damper assembly 40 is disposed between the first end of the first air guide 31 and the first end of the second air guide 32 and the cold air passage. The damper assembly 40 is used to control the opening and closing of the first air guide 31 and the second air guide 32 and the cold air passage.

[0089] Thus, the first air guide 31 and the second air guide 32 are connected to the first air outlet 21 and the second air outlet 22 respectively, allowing cold air to be guided to the upper and lower surfaces of the ice-making tray 12 according to the user's needs. This allows the user to adjust the airflow according to different ice-making requirements to achieve the best ice-making effect. Simultaneously, the design of the first air guide 31 and the second air guide 32 enables the cold air in the cold air channel to reach the upper and lower surfaces of the ice-making tray 12 more directly, reducing cold air loss during transmission and thus improving cooling efficiency. The modular design of the first air guide 31 and the second air guide 32 makes equipment maintenance and upgrades more convenient and reduces maintenance costs.

[0090] Please also refer to Figure 4 In some embodiments of this application, the first air guide 31 is provided with a first reinforcing plate 311.

[0091] In this way, the first reinforcing plate 311 can increase the structural strength and stability of the first air guide 31, preventing deformation or damage caused by pressure changes or other external forces during cold air flow. The first reinforcing plate 311 also helps to reduce vibration caused by airflow, thereby reducing noise. The first reinforcing plate 311 can also help guide and evenly distribute airflow, ensuring that cold air covers the upper surface of the ice-making tray more evenly and effectively.

[0092] In some embodiments of this application, the first reinforcing plate 311 extends along the height direction of the refrigerator 200, and the two ends of the first reinforcing plate 311 are respectively connected to the upper and lower surfaces of the first air guide 31, thereby providing sufficient strength for the first air guide 31.

[0093] Preferably, multiple first reinforcing plates 311 are provided, and the multiple first reinforcing plates 311 are arranged sequentially along the length direction of the refrigerator 200.

[0094] Please also refer to Figure 5 In some embodiments of this application, the second air guide 32 includes an air inlet 321, a connecting part 322, and an air outlet 323. The connecting part 322 connects the air inlet 321 and the air outlet 323. A first end of the second air guide 32 is disposed on the air inlet 321. A second end of the second air guide 32 is disposed on the air outlet 323, that is, the second air vent 22 is disposed on the air outlet 323.

[0095] The air intake 321 is located on the wall of the low-temperature storage compartment 202, and the opening of the air intake 321 is opposite to the cold air passage. The air intake 321 extends along the height direction of the refrigerator 200.

[0096] The opening of the air inlet 321 is directly opposite the cold air passage, allowing cold air to directly enter the second air guide 32. This ensures effective guidance of the cold air, reduces losses during airflow, and improves cooling efficiency. The extension design of the air inlet 321 along the height of the refrigerator ensures that cold air can quickly and directly reach the area below the ice tray 12, reducing losses during airflow and improving cooling efficiency.

[0097] The air outlet 323 is opposite to the lower surface of the ice-making tray 12.

[0098] Cold air is transported from the air inlet 321 to the air outlet 323 via the connecting part 322, and acts directly on the lower surface of the ice-making tray 12, ensuring uniform cooling of the bottom of the ice-making tray 12. This uniform cooling helps reduce air bubbles and impurities in the ice, improving the transparency and quality of the ice.

[0099] In some embodiments of this application, the air outlet 323 is provided with an air guiding surface 3231, which is inclined toward the lower surface of the ice-making tray 12 along the direction of cold air delivery.

[0100] By using the inclined air guide surface 3231, the cold air flowing out of the air outlet 323 can be effectively guided, reducing the airflow resistance in the air outlet 323, allowing the cold air to act directly on the lower surface of the ice-making tray 12, which helps to improve cooling efficiency, makes the cold air act more concentrated on the ice-making tray 12, and speeds up the ice-making speed.

[0101] In some embodiments of this application, the air outlet 323 is located below the ice-making tray 12, and the air guiding surface 3231 is the lower surface of the air outlet 323.

[0102] In some embodiments of this application, the air outlet 323 is provided with a second reinforcing plate 3232.

[0103] The second reinforcing plate 3232 increases the structural strength and stability of the air outlet 323, preventing deformation or damage caused by pressure changes or other external forces during cold air flow. The second reinforcing plate 3232 also helps reduce vibrations caused by airflow, thereby reducing noise. Furthermore, the second reinforcing plate 3232 helps guide and evenly distribute airflow, ensuring that cold air covers the lower surface of the ice-making tray 12 more evenly and effectively.

[0104] In some embodiments of this application, the second reinforcing plate 3232 extends along the height direction of the refrigerator 200, and the two ends of the second reinforcing plate 3232 are respectively connected to the upper surface of the air outlet 323 and the air guide surface 3231, thereby providing sufficient strength for the air outlet 323.

[0105] Preferably, multiple second reinforcing plates 3232 are provided, and the multiple second reinforcing plates 3232 are arranged sequentially along the length direction of the refrigerator 200.

[0106] Please also refer to Figure 6 In some embodiments of this application, the damper assembly 40 includes a first damper 41, a second damper 42, and a drive member 43. The first damper 41 is disposed between a first end of the first air guide 31 and the cold air passage. The second damper 42 is disposed between a first end of the second air guide 32 and the cold air passage. The drive member 43 is disposed between the first damper 41 and the second damper 42, and the drive member 43 is configured to control the opening and closing of the first damper 41 and the second damper 42.

[0107] By configuring the first air damper 41 and the second air damper 42, and precisely controlling their opening and closing via the drive unit 43, the cold air flow of the first air guide 31 and the second air guide 32 can be controlled independently. This independent control allows for adjustment of the cooling intensity of the upper and lower surfaces of the ice-making tray 12 according to specific ice-making needs, thereby optimizing the ice-making effect. Precise adjustment of the drive unit 43 helps maintain optimal cooling efficiency and ice quality under different operating conditions. Furthermore, controlling the drive unit 43 allows the dampers to be opened only when needed, reducing unnecessary cold air flow and thus lowering energy consumption.

[0108] In some embodiments of this application, the first damper 41 includes a first air duct 411 and a first baffle 412. The first air duct 411 connects the first end of the first air guide 31 with the cold air passage. The first baffle 412 is rotatably disposed in the first air duct 411. A drive member 43 is connected to the first air duct 411, and its drive end is connected to the first baffle 412, and is configured to drive the first baffle 412 to rotate, thereby opening or closing the first air duct 411.

[0109] By designing a rotatable first baffle 412 within the first air duct 411, the drive unit 43 can precisely control the opening of the first air duct 411, thereby helping to optimize the cold air flow and achieve a highly efficient ice-making process. Furthermore, precise control of the opening and closing of the first air duct 411 can reduce unnecessary cold air flow, thus lowering energy consumption. The drive unit 43 can respond to the system's control signals and quickly adjust the angle of the first baffle 412, ensuring timely system adjustments and improving the efficiency and reliability of the ice-making process.

[0110] In some embodiments of this application, the second damper 42 includes a second air duct 421 and a second baffle 422. The second air duct 421 connects the first end of the second air guide 32 with the cold air passage. The second baffle 422 is rotatably disposed in the second air duct 421. A drive member 43 is connected to the second air duct 421, and its drive end is connected to the second baffle 422, and is configured to drive the second baffle 422 to rotate, thereby opening or closing the second air duct 421.

[0111] By designing a rotatable second baffle 422 within the second air duct 421, the drive unit 43 can precisely control the opening of the second air duct 421, thereby helping to optimize the cold air flow and achieve a highly efficient ice-making process. Furthermore, precise control of the opening and closing of the second air duct 421 can reduce unnecessary cold air flow, thus lowering energy consumption. The drive unit 43 can respond to the system's control signals and quickly adjust the angle of the second baffle 422, ensuring timely system adjustments and improving the efficiency and reliability of the ice-making process.

[0112] In some embodiments of this application, the first damper 41 and the second damper 42 are dampers.

[0113] The installation of dampers offers the following benefits: Dampers enable precise airflow regulation; by adjusting the damper's opening, accurate control of cold air flow can be achieved, thereby optimizing the icing process. Simultaneously, dampers smoothly regulate airflow, reducing noise generated during air movement and providing a quieter operating environment. Dampers also buffer and regulate changes in airflow, reducing pressure fluctuations within the system, thus helping to protect other system components and extending equipment lifespan.

[0114] Figure 7 for Figure 1 This is one of the structural schematic diagrams of the ice maker in the refrigerator shown. Figure 8 for Figure 7 The diagram shows the exploded structure of an ice maker. Figure 9 for Figure 1 The second schematic diagram of the ice maker in the refrigerator shown. Figure 10 for Figure 9 The diagram shows the exploded structure of an ice maker.

[0115] like Figure 7 and Figure 9 As shown, the ice maker 10 also includes an ice-making support 11. The ice-making support 11 is disposed on the wall of the low-temperature storage chamber 202, thereby fixing the ice-making device 100 in the low-temperature storage chamber 202. The ice-making tray 12 is detachably installed in the ice-making support 11.

[0116] like Figure 8 and Figure 10 As shown, the ice-making tray 12 includes an ice tray support 121, an ice tray 122, and a flipping drive 123. The ice tray support 121 is detachably installed on the ice-making bracket 11. The ice tray 122 is fixedly installed inside the ice tray support 121. The ice tray support 121 can move back and forth within the ice-making bracket 11. If the user wants to remove the ice tray 122, the ice tray support 121 can be pulled forward to remove it from the ice-making bracket 11 for easy cleaning. If the user wants to put the ice tray support 121 back, the ice tray support 121 can be pushed backward to install it inside the ice-making bracket 11. After water is poured into the ice tray 122, it forms ice cubes under the action of cold air in the cold air passage. The flipping drive 123 is fixedly installed on the ice-making bracket 11 and connected to the ice tray 122. The flipping drive 123 is used to drive the ice tray 122 to flip, so that the ice cubes in the ice tray 122 fall into the ice storage box.

[0117] In some embodiments of this application, the ice maker 10 further includes an ice probe 13. The ice probe 13 is rotatably mounted on the ice-making support 11. The ice probe 13 is used to determine whether there is sufficient ice in the ice storage box.

[0118] The refrigerator 200 provided in this application includes a cabinet 201 and an ice-making device 100. The cabinet 201 has a low-temperature storage compartment 202, and a cold air passage is provided in the cabinet 201. The ice-making device 100 is located in the low-temperature storage compartment 202. The ice-making device 100 includes an ice-making tray 12 and an air guiding mechanism 20. The upper surface of the ice-making tray 12 has an opening for injecting water into the ice-making tray 12. The air guiding mechanism 20 is connected to the cold air passage and has a first air vent 21 and a second air vent 22. The first air vent 21 is configured to face the upper surface of the ice-making tray 12, and the second air vent 22 is configured to face the lower surface of the ice-making tray 12. The air guiding mechanism 20 includes an air damper assembly 40, which is configured to control the connection and closure of the first air vent 21 and the second air vent 22 with the cold air passage.

[0119] In this way, the air guiding mechanism 20 is connected to the cold air channel, giving the air guiding mechanism 20 a first air vent 21 and a second air vent 22. The air damper assembly 40 controls the connection and closure of the first air vent 21 and the second air vent 22 with the cold air channel, allowing the flow of cold air to be adjusted as needed, providing greater flexibility and controllability. It can be optimized according to different environmental conditions or ice-making requirements. When transparent ice is needed, the second air vent 22 can be connected to the cold air channel, while the first air vent 21 can be closed, thereby controlling the flow of cold air. This allows cold air to flow over the lower surface of the ice-making pan 12, accelerating the cooling of the water below the water in the ice-making pan 12. This results in the upper surface temperature being higher than other surfaces, causing the water to freeze more slowly on the upper surface. Air dissolved from other parts of the water in the ice-making pan 12 can be released into the atmosphere from the upper surface of the water, effectively reducing the generation of air bubbles during ice formation and improving the transparency of the ice. Transparent ice is more visually appealing, enhancing the overall visual effect and thus improving the overall user experience. Meanwhile, during defrosting, the first air vent 21 and the second air vent 22 can be closed by the damper assembly 40, thereby suppressing the temperature rise in the ice-making device 100.
