[0036] The present patent will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present patent, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of this patent.

[0037] Reference Figures 1 to 3 One embodiment of the present invention provides an ice-making device 1000.

[0038] The ice-making device 1000 may include a rotating member 1. The rotating member 1 rotates about a rotation axis 104. The axial direction 103 of the rotating member 1 refers to the direction in which the rotation axis 104 extends. The axial end 109 of the rotating member 1 refers to the end located on the rotation axis 104. The axial end 109 of the rotating member 1 includes a first axial end 1091 and a second axial end 1092. The radial direction 101 of the rotating member 1 refers to the direction perpendicular to and extending outward from the rotation axis 104. The circumferential direction 102 of the rotating member 1 refers to the direction around the rotation axis 104. The circumferential wall 107 of the rotating member 1 refers to the wall extending around the rotation axis 104. The rotation direction 105 of the rotating member 1 refers to the direction in which the rotating member 1 rotates about the rotation axis 104. The rotating member 1 can rotate clockwise or counterclockwise about the rotation axis 104. The rotation direction 105 of the rotating component 1 determines the direction of movement of the rotating component 1 in its circumferential direction 102.

[0039] In this embodiment, the rotating member 1 can be a cylindrical rotating cylinder. The rotation axis 104 of the rotating member 1 can be collinear with the center line of the rotating cylinder. The axial direction 103 of the rotating member 1 refers to the direction in which the center line of the rotating cylinder extends. The radial direction 101 of the rotating member 1 refers to the direction in which it extends from the center line of the rotating cylinder towards the cylinder wall. The circumferential direction 102 of the rotating member 1 refers to the direction in which it extends along the cylinder wall around the center line in a circular path. The circumferential wall 107 of the rotating member 1 refers to the cylinder wall extending around the center line of the rotating cylinder in a circular path. The rotation direction 105 of the rotating member 1 refers to the direction in which the rotating cylinder rotates around its center line. In other embodiments of the present invention, the rotating member 1 can also be other shapes, such as a rod shape.

[0040] The ice-making device 1000 may include an ice-making component 2. The ice-making component 2 may include an ice-making rod 201 disposed on the rotating component 1 and extending outward along the radial direction 101 of the rotating component 1. The ice-making rod 201 may be disposed on the circumferential wall 107 of the rotating component 1. The ice-making component 2 may include multiple ice-making rods 201. The multiple ice-making rods 201 may be spaced apart along the axial direction 103 of the rotating component 1, or spaced apart along the circumferential direction 102 of the rotating component 1. When the rotating component 1 rotates, the ice-making rods 201 rotate with the rotating component 1.

[0041] The ice-making apparatus 1000 may include a water supply device 3. The water supply device 3 may include a water supply chamber 301 located at least partially on the radial 101 side of the rotating member 1. The water supply chamber 301 may provide water for forming ice 12 on the ice-making rod 201.

[0042] The ice-making device 1000 may include an ice-removing component 4. At least a portion of the ice-removing component 4 is located on the radial 101 side of the rotating component 1 and outside the water supply chamber 301. The ice-removing component 4 can be used to remove ice 12 formed on the ice-making rod 201.

[0043] The ice-making device 1000 may include a refrigeration system 5. The refrigeration system 5 may include components such as a compressor, condenser, expansion valve, and evaporator, which work together through a refrigeration cycle. The refrigeration cycle generally includes a compression process, a condensation process, an expansion process, and an evaporation process. In the compression process, the compressor compresses the refrigerant gas, heating it and increasing its pressure. In the condensation process, the high-pressure hot gas releases heat in the condenser, cooling the refrigerant and condensing it into a liquid state. In the expansion process, the liquid refrigerant passes through the expansion valve (throttle valve), its pressure decreases, and it enters the evaporator. In the evaporation process, in the evaporator, the low-pressure refrigerant absorbs heat from the surrounding environment and evaporates into a gas. This process causes the temperature of the surrounding environment to decrease. This cycle of compression, condensation, expansion, and evaporation is repeated continuously, thereby achieving a continuous cooling effect for the refrigeration system 5. The refrigeration system 5 is used to supply cooling to the ice-making rod 201. The refrigeration system 5 can supply cooling directly to the ice-making rod 201 or indirectly to the ice-making rod 201 through a rotating component 1, etc.

[0044] The ice-making apparatus 1000 may include a drive device 6. The drive device 6 is used to drive the rotating component 1 to rotate. In this embodiment, the drive device 6 may include a motor. A rotating shaft 1010 may be provided inside the rotating drum. The center line of the rotating shaft 1010 may be collinear with the rotation axis 104 of the rotating drum, and the rotating shaft 1010 may extend along the axial direction 103 of the rotating drum. The rotating shaft 1010 may be connected to the motor shaft of the motor, thereby realizing the rotation of the rotating component 1 by driving the motor.

[0045] When the rotating part 1 rotates, it drives the ice-making rod 201 to be at least partially immersed in the water in the water supply chamber 301 to form ice 12 on the ice-making rod 201, or drives the ice-making rod 201 through the de-icing part 4 to remove the ice 12 from the ice-making rod 201.

[0046] By rotating the rotating component 1, the ice-making rod 201 can be periodically immersed in the water in the water supply chamber 301. This dynamic immersion allows each ice-making rod 201 to obtain a certain amount of water within a specific time, thereby forming ice 12. The rotation allows for precise control of the immersion time and depth of the ice-making rod 201 in the water, which helps to precisely control the size of the ice blocks formed on the ice-making rod 201 and improve the quality of the ice blocks.

[0047] Driven by the rotating component 1, the ice-making rod 201 passes through the de-icing component 4, which is responsible for separating the formed ice 12 from the ice-making rod 201. Through rotation, the ice-making rod 201 and the de-icing component 4 periodically come into contact, allowing the ice to detach under appropriate time and conditions. This design ensures a smooth and efficient de-icing process. The rotating component 1 drives the ice-making rod 201 to complete the ice-making and de-icing processes. This allows for alternating ice-making and de-icing processes on the same ice-making rod 201, and also allows for simultaneous ice-making and de-icing on different ice-making rods 201 when multiple ice-making rods 201 are present. This achieves continuous ice-making and improves production efficiency, increasing equipment utilization.

[0048] The dynamic immersion and de-icing operations brought about by the rotating component 1 allow for precise control of the ice-making and de-icing processes of each ice-making rod 201, thereby ensuring the consistency of the ice 12's quality. This design, which uses the rotating component 1 to drive the ice-making rods 201 for ice-making and de-icing operations, greatly improves the automation level, production efficiency, and ice quality of the ice-making device 1000. It enables the production of bullet ice while reducing energy consumption and featuring a compact structure that minimizes space occupation.

[0049] Reference Figure 1 , Figure 2 , Figure 4 In one embodiment of the present invention, the water supply device 3 further includes a water storage chamber 302. The water supply device 3 also includes a water supply pipe 303. The water supply pipe 303 can be used to transport water from the water storage chamber 302 to the water supply chamber 301. The water supply device 3 may also include a water supply pump. The water supply pump can be used to transport water from the water storage chamber 302 to the water supply chamber 301 through the water supply pipe 303.

[0050] The main function of the water supply chamber 301 is to directly supply water to the ice-making rods 201 for ice-making operations. The water supply chamber 301 can be designed to control the water flow and distribution, ensuring that each ice-making rod 201 receives the appropriate amount of water to improve ice-making efficiency and the uniformity of the ice. The main function of the water storage chamber 302 is to store a certain amount of water and replenish the water supply chamber 301 as needed. The water storage chamber 302 ensures that the water supply chamber 301 has a sufficient water supply, guaranteeing the continuity of the ice-making process. The water storage chamber 302 provides a sufficient water source guarantee, while the water supply chamber 301 precisely controls the water supply process. Through the coordinated work of the water supply chamber 301 and the water storage chamber 302, the entire water supply device 3 can achieve efficient and stable water supply management, meeting the needs of ice-making operations and ensuring ice-making quality and efficiency.

[0051] Reference Figure 4In one embodiment of the present invention, the water supply pipe 303 is positioned at an outlet height in the water supply chamber 301 that is higher than or equal to a preset water supply level. The water supply device 3 may also include a return water pipe 304. The return water pipe 304 can be used to return water in the water supply chamber 301 that is higher than the preset water supply level to the water storage chamber 302.

[0052] The preset water supply level refers to the target height that the water in the water supply chamber 301 needs to reach, as set by the designer in advance. The preset water supply level determines the immersion depth of the ice-making rod 201 when submerged in water. By adjusting the preset water level, the immersion depth of the ice-making rod 201 can be precisely controlled, thereby controlling the size of the ice blocks. The higher the water level, the deeper the ice-making rod 201 is immersed, and the larger the ice blocks; conversely, the lower the water level, the smaller the ice blocks. When the water level is higher than the preset water supply level, excess water can automatically flow back to the water storage chamber 302 through the return water pipe 304. If the water level in the water supply chamber 301 is lower than the preset water level, the water supply pipe 303 will continue to replenish the water supply to ensure that the water level in the water supply chamber 301 reaches the preset standard. The preset water level ensures that the amount of water immersed in the ice-making rod 201 remains consistent in each ice-making cycle, thereby producing ice blocks of consistent quality and avoiding uneven ice block size caused by water level changes.

[0053] By setting the outlet height of the water supply pipe 303 in the water supply chamber 301 to be higher than or equal to the preset water supply level, and by setting the return water pipe 304, it is helpful to promote the flow of water in the water supply chamber 301, thereby making the ice 12 generated on the ice-making rod 201 transparent ice 12. Stagnant water is prone to the formation of air bubbles or impurities. These air bubbles and impurities will be trapped in the ice 12 during the freezing process, causing the ice to be opaque. By keeping the water flowing, the generation of air bubbles can be effectively reduced, making the water purer when freezing, and the generated ice more transparent, thus improving the transparency and quality of the ice and realizing the production of transparent bullet ice 12.

[0054] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the ice-making apparatus 1000 includes an ice-making chamber 8. A rotating member 1 is at least partially located within the ice-making chamber 8, an ice-removing member 4 is located within the ice-making chamber 8, and a refrigeration system 5 supplies cooling to the ice-making rod 201 and the ice-making chamber 8 via the rotating member 1.

[0055] Both the rotating component 1 and the ice-making rod 201 can be made of metal. The refrigeration system 5 can directly exchange heat with the rotating component 1 through air cooling or direct cooling to reduce the temperature of the rotating component 1. The rotating component 1 can directly exchange heat with the air and ice-making rod 201 inside the ice-making chamber 8 through its wall to reduce the temperature of the ice-making chamber 8 and ice-making rod 201 through direct cooling. By setting up a relatively closed ice-making chamber 8 and supplying cooling to the ice-making chamber 8 and ice-making rod 201 through the rotating component 1, it is possible to prevent the ice-making chamber 8, ice-making rod 201, ice-removing component 4, etc., from contacting the outside air, ensuring the cleanliness of the inside of the ice-making chamber 8, ensuring the cleanliness of the ice 12 inside the ice-making chamber 8, and preventing the adhesion of odors, bacteria, and other contaminants on the ice 12.

[0056] Reference Figures 1 to 3 In one embodiment of the present invention, the ice-making apparatus 1000 may include a fixed base 7. A rotating member 1 is rotatably connected to the fixed base 7. The refrigeration system 5 includes a refrigerant pipe 501 fixedly connected to the fixed base 7. A receiving cavity 106 is formed inside the rotating member 1. The refrigerant pipe 501 is at least partially located within the receiving cavity 106.

[0057] The refrigerant pipe 501 located in the accommodating cavity 106 and the refrigerant pipes of other parts of the refrigeration system 5 can be pre-installed inside and outside the ice-making chamber 8 at the same time, or the refrigerant pipes of other parts of the refrigeration system 5 can be pre-installed first and then connected to the refrigerant pipe 501 located in the accommodating cavity 106.

[0058] The receiving cavity 106 can extend along the rotation axis 104 of the rotating member 1. The centerline of the receiving cavity 106 can be collinear with the centerline of the rotating member 1. In this embodiment, the receiving cavity 106 is a cylindrical cavity disposed at the center of the rotating member 1. In other embodiments, the receiving cavity 106 can also be an annular cavity spaced a certain distance from the center of the rotating member 1.

[0059] The fixed base 7 provides support for the rotating component 1. When the motor drives the rotating component 1 to rotate, the rotating component 1 rotates relative to the fixed base 7, while the refrigerant pipe 501 remains stationary. This not only ensures the stability and reliability of the rotating component 1's rotation but also facilitates the installation of the refrigerant pipe 501, preventing the refrigerant pipe 501 from twisting or being damaged when the rotating component 1 rotates.

[0060] By placing the refrigerant pipe 501 within the receiving cavity 106 inside the rotating component 1, the refrigerant can circulate directly within the rotating component 1, allowing the cooling energy to be rapidly transferred to the ice-making rod 201 and the ice-making chamber 8. This enables direct cooling from the refrigeration system 5 to the rotating component 1, achieving rapid cooling and ice-making of the ice-making rod 201, improving ice-making efficiency, and ensuring the cleanliness of the ice-making chamber 8. Placing the refrigerant pipe 501 within the receiving cavity 106 also reduces heat loss during the transfer process, improving refrigeration efficiency and ensuring more cooling energy is directly used for ice making. The fixing base 7 ensures the stability and reliability of the fit between the rotating component 1 and the refrigerant pipe 501, and also makes the ice-making device 1000 more compact, optimizing space utilization and making the entire ice-making device 1000 more efficient, stable, and easy to use.

[0061] In one embodiment of the present invention, the refrigeration system 5 may further include a protective sleeve disposed between the inner wall of the accommodating cavity 106 and the refrigerant pipe 501. The protective sleeve may be fixedly connected to the fixing seat 7 and / or the refrigerant pipe 501. Lubrication or bearings may be provided between the outer side of the protective sleeve and the inner wall of the accommodating cavity 106 to reduce friction between the protective sleeve and the inner wall of the accommodating cavity 106 and protect the refrigerant pipe 501.

[0062] Reference Figures 1 to 3 In one embodiment of the present invention, the rotating shaft 1010 of the rotating member 1 may include a first shaft end near the first axial end 1091 and a second shaft end near the second axial end 1092. The first shaft end may be rotatably connected to the fixed base 7. The second shaft end may be connected to the driving device 6. A receiving cavity 106 is formed inside the rotating shaft 1010. The second shaft end may be closed. The first shaft end may have a receiving cavity opening communicating with the inside and outside of the receiving cavity 106. The refrigerant pipe 501 may be installed in the receiving cavity 106 through the receiving cavity opening.

[0063] The axial end 109 of the rotating component 1 can be opposite to the wall of the ice-making chamber 8. The wall of the ice-making chamber 8 may include a first wall 804 and a second wall 805. The first wall 804 can be opposite to the first axial end 1091. The second wall 805 can be opposite to the second axial end 1092. The driving device 6 can be fixed to the second wall 805. The fixing seat 7 can be fixed to the first wall 804. The fixing seat 7 and the first wall 804 can be integrally formed.

[0064] In one embodiment of the present invention, the wall of the ice-making chamber 8 is provided with a protruding edge 803 that seals with the periphery of the axial end 109 of the rotating member 1.

[0065] Specifically, the first wall 804 has a mounting opening opposite to the cavity opening of the accommodating cavity 106, and the first wall 804 is provided with a protruding edge 803 that mates with the periphery of the first axial end 1091. The protruding edge 803 on the first wall 804 is located outside the mounting opening. The refrigerant pipe 501 of the refrigeration system 5 extends into the accommodating cavity 106 through the mounting opening. The protruding edge 803 is used to seal against the axial end 109 of the rotating member 1 to prevent the internal space of the ice-making chamber 8 from communicating with the accommodating cavity 106 or any space outside the ice-making chamber 8.

[0066] Reference Figure 1 and Figure 4 In one embodiment of the present invention, the wall of the water supply chamber 301 is formed with an ice-making rod opening 305 for the ice-making rod 201 to enter and exit the water supply chamber 301. The ice-making rod opening 305 includes an inlet portion 3051 and an outlet portion 3052. The opening size of the inlet portion 3051 is larger than the diameter of the ice-making rod 201. The opening size of the outlet portion 3052 is larger than the size of the ice 12 on the ice-making rod 201. The number of ice-making rod openings 305 can be consistent with the number of ice-making components 2 arranged along the axial direction 103 of the rotating member 1. Preferably, two ice-making rods 201 are spaced apart along the axial direction 103 of the rotating member 1. Correspondingly, two ice-making rod openings 305 are spaced apart along the axial direction 103 of the rotating member 1 on the wall of the ice-making chamber 8. By setting the ice-making rod opening 305, it is possible to ensure that the ice-making rod 201 without ice 12 can smoothly enter the water supply chamber 301, and that the ice-making rod 201 carrying ice 12 can smoothly leave the ice-making chamber 8. The size of the ice-making rod opening 305 is minimized to reduce the exchange of cold energy between the water supply chamber 301 and the ice-making chamber 8, and to prevent the water in the water supply chamber 301 from freezing.

[0067] Reference Figure 1 , Figure 2 , Figure 4 The water supply chamber 301 can be located below the ice-making chamber 8. The top wall of the water supply chamber 301 can serve as the bottom wall of the ice-making chamber 8. An ice-making rod opening 305 can be formed in the top wall of the water supply chamber 301. An insulation layer can be provided around the water supply chamber 301 to prevent the water inside the water supply chamber 301 from freezing. The rotating component 1 can be horizontally arranged inside the ice-making chamber 8 and located above the water supply chamber 301.

[0068] Reference Figure 1 In one embodiment of the present invention, the de-icing member 4 is closer to the inlet rod portion 3051 and farther away from the outlet rod portion 3052 in the rotation direction 105 of the rotating member 1.

[0069] By positioning the de-icing component 4 close to the rod inlet 3051 in the rotation direction 105 of the rotating component 1, the de-iced ice-making rod 201 can quickly enter the water supply chamber 301 through the rod inlet 3051 to form ice 12.

[0070] By moving the de-icing component 4 away from the rod-out portion 3052 in the rotation direction 105 of the rotating component 1, the ice-making rod 201, which leaves the water supply chamber 301 via the rod-out portion 3052, can rotate to the de-icing component 4 only after a certain period of time. This allows the ice 12 on the ice-making rod 201 sufficient time to exchange heat with the cold air in the ice-making chamber 8, thus providing additional cooling and hardening of the ice 12 before de-icing. This ensures that the moisture on the surface of the ice is completely frozen, preventing liquid water from remaining on the surface of the ice after de-icing, ensuring that the ice is dry, and preventing the ice from sticking together after de-icing.

[0071] Reference Figure 4 In one embodiment of the present invention, the water supply device 3 includes a first flap 306 for opening and closing the inlet rod portion 3051 and a second flap 307 for opening and closing the outlet rod portion 3052. Both the first flap 306 and the second flap 307 can be flipped under the action of the ice-making rod 201. The first flap 306 can be flipped inwards towards the water supply chamber 301 under the action of the ice-making rod 201. The second flap 307 can be flipped outwards towards the water supply chamber 301 under the action of the ice-making rod 201.

[0072] An automatic return structure can be provided between the first flip cover 306, the second flip cover 307 and the wall of the water supply chamber 301. The automatic return structure may include springs, etc., so that after the first flip cover 306 and the second flip cover 307 are flipped under the action of the ice-making rod 201, they can automatically return to the state of closing the rod inlet 3051 and the rod outlet 3052, so as to prevent the cold air from the ice-making chamber 8 from entering the water supply chamber 301 in large quantities through the rod inlet 3051 and the rod outlet 3052, causing the water in the water supply chamber 301 to freeze.

[0073] Reference Figures 1 to 4 In one embodiment of the present invention, the ice-making rod opening 305 includes a middle portion 3053 located between the rod inlet portion 3051 and the rod outlet portion 3052. The middle portion 3053 is in a sealing fit with the circumferential wall 107 of the rotating member 1. The opening size of the middle portion 3053 is larger than the rod diameter of the ice-making rod 201. The periphery of the middle portion 3053 can fit against the circumferential wall 107 of the rotating member 1 to achieve a sealing fit between the middle portion 3053 and the circumferential wall 107 of the rotating member 1, thereby preventing a large amount of cold air from the ice-making chamber 8 from entering the water supply chamber 301 through the middle portion 3053 and causing the water in the water supply chamber 301 to freeze.

[0074] The rotation axis 104 of the rotating member 1 extends horizontally. The top wall of the water supply chamber 301 may include a horizontally extending first straight wall portion 3011, a second straight wall portion 3012, and a curved wall portion 3013 located between the first straight wall portion 3011 and the second straight wall portion 3012. The first straight wall portion 3011 and the second straight wall portion 3012 are located on both sides of the rotating member 1, respectively. The height of the first straight wall portion 3011 and the second straight wall portion 3012 is lower than the height of the rotation axis 104 of the rotating member 1, but higher than the bottom end of the rotating member 1. The curved wall portion 3013 is in contact with the outer surface of the circumferential wall 107 of the rotating member 1 located below the first straight wall portion 3011 and the second straight wall portion 3012. The first straight wall portion 3011 may form an insert rod portion 3051, the second straight wall portion 3012 may form an outlet rod portion 3052, and the curved wall portion 3013 may form a middle portion 3053. This design reduces the space occupied by the rotating component 1 in the ice-making chamber 8, making the ice-making device 1000 more compact, and also prevents a large amount of cold air from the ice-making chamber 8 from entering the water supply chamber 301.

[0075] Reference Figure 1 and Figure 5 In one embodiment of the present invention, the de-icing component 4 includes a curved plate 401 spaced apart from the circumferential wall 107 of the rotating component 1. The radius of curvature of the curved plate 401 gradually increases along the rotation direction 105 of the rotating component 1. The curved plate 401 is formed with a de-icing opening 402 extending along the rotation direction 105 of the rotating component 1. The de-icing opening 402 includes an ice-in portion 4021 and a de-icing portion 4022. The opening size of the ice-in portion 4021 is larger than the size of the ice 12 on the ice-making rod 201. The opening size of the de-icing portion 4022 is larger than the diameter of the ice-making rod 201 and smaller than the size of the ice 12 on the ice-making rod 201.

[0076] The curved plate 401 includes a first side facing the circumferential wall 107 of the rotating member 1 and a second side facing away from the circumferential wall 107. When the ice-making rod 201 carrying ice 12 rotates with the rotating member 1 in the rotation direction 105, at least a portion of the rod of the ice-making rod 201 and the ice 12 on the ice-making rod 201 first enter from the first side of the curved plate 401 through the ice-inlet section 4021 to the second side of the curved plate 401, and then move to the ice-removing section 4022. Since the opening size of the ice-removing section 4022 is larger than the diameter of the ice-making rod 201 and smaller than the size of the ice 12 on the ice-making rod 201, the first side of the curved plate 401 at the edge of the ice-removing section 4022... The two side walls will abut against the end of the ice 12 on the ice-making rod 201. Since the radius of curvature of the curved plate 401 gradually increases along the rotation direction 105 of the rotating member 1, as the ice-making rod 201 rotates along the rotation direction 105, under the support of the second side wall of the curved plate 401, the ice 12 on the ice-making rod 201 will gradually move away from the ice-making rod 201 until it is detached from the ice-making rod 201. After the ice is detached, the rod part of the ice-making rod 201 can return to the first side from the second side of the curved plate 401 through the ice-detaching part 4022.

[0077] Reference Figure 1 In one embodiment of the present invention, the ice-making device 1000 may include an ice storage box 9. The ice storage box 9 may include an ice dispensing port and a lid 901 for opening and closing the ice dispensing port. The ice-making device 1000 may also include an ice guiding channel 10. The ice guiding channel 10 may be used to transport ice blocks detached from the ice-removing component 4 to the ice storage box 9.

[0078] Reference Figure 1 and Figure 5 The ice guiding channel 10 may include a first ice guiding opening disposed in the ice-making chamber 8. The wall of the ice-making chamber 8 may have a first clearance opening that mates with the first ice guiding opening. The curved plate 401 may be vertically inclined, with the ice inlet 4021 located above the ice removal part 4022, that is, the curved plate 401 gradually extends downwards along the rotation direction 105 of the rotating member 1. The lower end of the curved plate 401 may be connected to the lower end of the first ice guiding opening. Ice 12 that falls off the ice-making rod 201 may slide downwards along the second side wall of the curved plate 401 and then enter the ice guiding channel 10 through the first ice guiding opening.

[0079] The ice guiding channel 10 may include a second ice guiding port disposed in the ice storage box 9. The wall of the ice storage box 9 may have a second clearance opening that mates with the second ice guiding port. The ice storage box 9 may be disposed outside the ice making chamber 8 and below the ice making chamber 8. Ice 12 entering the ice guiding channel 10 from the first ice guiding port slides downward along the ice guiding channel 10 under the action of gravity and enters the ice storage box 9 through the second ice guiding port.

[0080] Ice 12 detached from the de-icing component 4 is directly transferred to the ice storage box 9 via the ice guiding channel 10, preventing the ice 12 from coming into contact with odorous environments during transportation and ensuring the cleanliness of the ice 12. The lid 901 of the ice storage box 9 can seal the ice dispensing port to prevent odors, bacteria, or other contaminants from entering the ice storage box 9, ensuring the cleanliness of the ice 12 during storage. By designing the ice guiding channel 10 and the sealed ice storage box 9, the ice 12 inside the ice storage box 9 is effectively prevented from contacting air containing odors, reducing odor adsorption and maintaining the freshness and purity of the ice 12.

[0081] Reference Figures 1 to 3 In one embodiment of the present invention, the ice-making rod 201 may include a first ice-making rod 202 and a second ice-making rod 203 spaced apart along the circumference 102 of the rotating member 1. When the rotating member 1 rotates to a preset position, at least one of the first ice-making rod 202 and the second ice-making rod 203 is immersed in the water in the water supply chamber 301, and the other is located outside the water supply chamber 301.

[0082] While one ice-making rod 201 is immersed in the water supply chamber 301 to make ice, another ice-making rod 201 can remove ice at the de-icing component 4. Alternatively, another ice-making rod 201 can be positioned between the water supply chamber 301 and the de-icing component 4 to increase the hardness of the ice 12 on the ice-making rod 201 through the cold air from the ice-making chamber 8.

[0083] By subjecting ice 12 to additional cooling and hardening before de-icing, it is ensured that the surface moisture of the ice is completely frozen, preventing liquid water from remaining on the surface after de-icing. This ensures the ice is dry and prevents the de-iced ice 12 from being wet, thus preventing ice blocks from sticking together inside the ice storage box 9. Sufficiently cooled ice not only has its surface moisture completely frozen, but its internal structure is also denser and harder, resulting in higher quality ice.

[0084] By alternately immersing the ice-making rods 201 in the water supply chamber 301, the device can achieve continuous ice making, allowing the ice-making process to proceed without interruption and greatly improving ice-making efficiency.

[0085] Reference Figures 1 to 3 In one embodiment of the present invention, the ice-making rod 201 may further include a third ice-making rod 204. The third ice-making rod 204 may be spaced apart from the first ice-making rod 202 and the second ice-making rod 203 along the circumferential direction 102 of the rotating member 1. When the rotating member 1 rotates to a preset position, one of the ice-making rods 201, including the first ice-making rod 202, the second ice-making rod 203, and the third ice-making rod 204, is at least partially immersed in the water in the water supply chamber 301 to form ice 12 on the ice-making rod 201. One ice-making rod 201 is located at the de-icing member 4 to allow the ice 12 on the ice-making rod 201 to fall off. Another ice-making rod 201 is located between the water supply chamber 301 and the de-icing member 4 to increase the hardness of the ice 12 on the ice-making rod 201 by the cold air in the ice-making chamber 8.

[0086] While one ice-making rod 201 is immersed in the water supply chamber 301 to make ice, another ice-making rod 201 is removing ice, and ice 12 on another ice-making rod 201 is further cooled and hardened by the cold air in the ice-making chamber 8. This cycle ensures that ice making, ice hardening and dehydration, and ice removal occur sequentially in each cycle, greatly improving ice-making efficiency. This design reduces the waiting time between ice making, ice hardening, and ice removal, achieving synchronous operation of ice making, ice hardening, and ice removal, shortening the overall ice-making cycle, and ensuring a fast and high-quality supply of ice.

[0087] Preferably, the first ice-making rod 202, the second ice-making rod 203, and the third ice-making rod 204 are evenly distributed along the circumference 102 of the rotating member 1, and are spaced 120° apart from each other.

[0088] Reference Figures 1 to 3 , Figure 6In one embodiment of the present invention, an air duct 108 may be formed inside the rotating member 1. The refrigeration system 5 may include an evaporator chamber 502. The evaporator chamber 502 is connected to the air inlet 1081 of the air duct 108 to supply cold air to the air duct 108. The driving device 6 is used to drive the rotating member 1 to rotate.

[0089] By setting an air duct 108 inside the rotating component 1 and supplying cold air to the evaporator chamber 502, air cooling from the refrigeration system 5 to the rotating component 1 can be achieved. Since the air duct 108 is set inside the rotating component 1 and directly connected to the evaporator chamber 502, the air in the air duct 108 and the evaporator chamber 502 can be prevented from communicating with the ice-making chamber 8, ensuring the cleanliness of the refrigeration chamber and preventing contaminants such as odors and bacteria from polluting the ice-making chamber 8. It can also reduce the weight of the rotating component 1 and ensure the uniformity of the temperature of the circumferential wall 107 of the rotating component 1.

[0090] Reference Figures 1 to 3 , Figure 6 In one embodiment of the present invention, the circumferential wall 107 of the rotating member 1 is used to mount the ice-making member 2. The water supply device 3 is used to supply water to the ice-making member 2 to form ice 12 on the ice-making member 2. The driving device 6, the water supply device 3, and the ice-making member 2 can all be as described above. That is, the ice-making member 2 is an ice-making rod 201 extending outward along the radial direction 101 of the rotating member 1. The water supply device 3 includes a water supply chamber 301 located at least partially on the radial direction 101 side of the rotating member 1. When the rotating member 1 rotates, it drives the ice-making rod 201 to be at least partially immersed in the water in the water supply chamber 301 to form ice 12 on the ice-making rod 201, or drives the ice-making rod 201 away from the water supply chamber 301. With this configuration, it is possible to achieve air cooling to the rotating member 1, cooling to the ice-making chamber 8 and the ice-making member 2 through the rotating member 1, and ice making through the ice-making member 2, ensuring the cleanliness of the ice 12 made by the ice-making member 2.

[0091] In another embodiment of the invention, the circumferential wall 107 of the rotating member 1 is used for ice making. A water supply device 3 supplies water to the circumferential wall 107 to form ice 12 on it. That is, the ice-making component 2 can be omitted from the circumferential wall 107 of the rotating member 1, and ice can be made directly using the circumferential wall 107 of the rotating member 1. The ice-making device 1000 may include a scraper that cooperates with the circumferential wall 107 of the rotating member 1. The refrigeration system 5 can supply cooling to the rotating member 1 using the air-cooling method described above, i.e., an air duct 108 communicating with the evaporator chamber 502 is formed inside the rotating member 1. The water supply device 3 can spray water onto the circumferential wall 107 of the rotating member 1 through a water spray structure, or the water supply device 3 may include a water tank, with a portion of the circumferential wall 107 of the rotating member 1 immersed in the water tank.

[0092] When the rotating component 1 rotates, the water adhering to the circumferential wall 107 of the rotating component 1 exchanges heat with the circumferential wall 107 and quickly condenses into ice 12. The ice 12 on the circumferential wall 107 is scraped off by the scraper. The air-cooling system supplies cooling to the circumferential wall 107 of the rotating component 1, so that the temperature of the circumferential wall 107 is evenly distributed, avoiding local overcooling or overheating, and ensuring that the temperature of the circumferential wall 107 of the rotating component 1 can be reduced rapidly. When water comes into contact with the circumferential wall 107, heat exchange occurs immediately and it freezes into ice 12 quickly. The continuous rotation of the rotating component 1, combined with the operation of the water supply device 3 and the scraper, allows the ice-making process to continue continuously without additional waiting time. The ice-making efficiency is thus significantly improved, enabling the efficient and high-quality production of flake ice 12, and also ensuring the cleanliness of the ice 12 and the ice-making chamber 8.

[0093] Reference Figures 1 to 3 , Figure 6 In one embodiment of the present invention, the refrigeration system 5 can supply cooling to the rotating component 1 solely through air cooling, that is, the refrigeration system 5 supplies cooling to the rotating component 1 solely through the air duct 108 within the rotating component 1. Multiple spaced fins 1011 can be provided between the rotating shaft 1010 at the center of the rotating component 1 and the circumferential wall 107 of the rotating component 1. The space between the fins 1011 can form the air duct 108. The fins 1011 can be made of metal, which not only provides heat conduction and improves the cooling efficiency of the rotating component 1, but also reduces the weight of the rotating component 1 and ensures the structural strength of the rotating component 1.

[0094] In one embodiment of the present invention, the refrigeration system 5 can supply cooling to the rotating part 1 only through the direct cooling method described above, that is, the refrigeration system 5 supplies cooling to the rotating part 1 only by providing a refrigerant pipe 501 in the accommodating cavity 106 of the rotating part 1.

[0095] In one embodiment of the present invention, the refrigeration system 5 can supply cooling to the rotating component 1 through a combination of direct cooling and air cooling. Specifically, the ice-making device 1000 includes a fixed base 7, the rotating component 1 is rotatably connected to the fixed base 7, the refrigeration system 5 also includes a refrigerant pipe 501 fixedly connected to the fixed base 7, and the rotating component 1 further includes a receiving cavity 106. The refrigerant pipe 501 is at least partially located within the receiving cavity 106, and the rotating component 1 also has an air duct 108. The evaporator chamber 502 of the refrigeration system 5 communicates with the air duct 108 to supply cooling to the air duct 108. The air duct 108 can be located outside the receiving cavity 106. Preferably, the receiving cavity 106, as described above, can be located within the rotating shaft 1010 of the rotating component 1, and the air duct 108, as described above, can be located between the rotating shaft 1010 and the circumferential wall 107. Using a combination of direct cooling and air cooling can improve the cooling efficiency of the rotating component 1 and ensure the temperature uniformity of the circumferential wall 107 of the rotating component 1.

[0096] Reference Figures 1 to 3 ,Figures 6 to 8 In one embodiment of the present invention, the circumferential wall 107 may be located inside the ice-making chamber 8. The ice-making component 2 may be located inside the ice-making chamber 8. The air inlet 1081 and air outlet 1082 of the air duct 108 are both connected to the space outside the ice-making chamber 8. In this way, the space inside the ice-making chamber 8 can be prevented from communicating with other spaces through the air duct 108, thus ensuring the cleanliness of the ice-making chamber 8.

[0097] Reference Figure 2 , Figure 7 In one embodiment of the present invention, the axial end 109 of the rotating member 1 is opposite to the wall of the ice-making chamber 8. The air inlet 1081 and the air outlet 1082 of the air duct 108 are both provided at the axial end 109 of the rotating member 1. The wall of the ice-making chamber 8 is formed with a first opening 801 and a second opening 802 that are respectively sealed and connected to the air inlet 1081 and the air outlet 1082.

[0098] Specifically, the air inlet 1081 can be located at the first axial end 1091 of the rotating member 1. The air outlet 1082 can be located at the second axial end 1092 of the rotating member 1. The first wall 804 can have a first opening 801. The second wall 805 can have a second opening 802. When the refrigeration system 5 supplies cooling to the ice-making member 2 using a combination of air cooling and direct cooling, the aforementioned mounting opening and the first opening 801 can be the same opening.

[0099] By sealing the air inlet 1081 and air outlet 1082 with the first opening 801 and the second opening 802, the ice-making chamber 8 can be prevented from communicating with the external space, thus ensuring the cleanliness of the interior of the ice-making chamber 8.

[0100] Reference Figure 3 , Figure 6 In one embodiment of the present invention, the wall of the ice-making chamber 8 is provided with a protruding edge 803 that seals with the periphery of the axial end 109 of the rotating member 1. The first wall 804 and the second wall 805 may both be provided with a protruding edge 803 that seals with the periphery of the axial end 109 of the rotating member 1, so as to prevent the ice-making chamber 8 from communicating with the external space and to ensure the cleanliness of the interior of the ice-making chamber 8.

[0101] Reference Figure 8 , Figure 3 , Figure 6 In one embodiment of the present invention, the water supply device 3 includes a water storage chamber 302 located at least partially outside the ice-making chamber 8. Cold air flowing from the air outlet 1082 is directed towards the water storage chamber 302. The water storage chamber 302 can be as described above. Specifically, the evaporator chamber 502 can be located on the side of the first wall 804 of the ice-making chamber 8. The water storage chamber 302 can be located on the side of the second wall 805 of the ice-making chamber 8. By directing the cold air flowing from the air outlet 1082 towards the water storage chamber 302, the temperature of the water in the water storage chamber 302 can be reduced, thereby improving ice-making efficiency.

[0102] Reference Figure 8 , Figure 3 , Figure 6 In one embodiment of the present invention, the refrigeration system 5 includes an air outlet damper. The air outlet damper is used to regulate the volume of cold air blown from the air outlet 1082 to the water storage chamber 302. The air outlet damper can control the volume of cold air blown from the air outlet 1082 to the water storage chamber 302 by adjusting the airflow direction, or by adjusting the opening degree of the air outlet 1082, i.e., the extent to which the air outlet 1082 is open.

[0103] Reference Figure 3 , Figure 6 In one embodiment of the present invention, the refrigeration system 5 further includes an air inlet damper. The air inlet damper is used to regulate the volume of cold air entering the air duct 108 from the evaporator chamber 502 through the air inlet 1081. The air inlet damper can control the volume of cold air entering the air duct 108 from the evaporator chamber 502 through the air inlet 1081 by adjusting the air direction, or it can control the volume of cold air entering the air duct 108 from the evaporator chamber 502 through the air inlet 1081 by adjusting the opening degree of the air inlet 1081.

[0104] Reference Figures 1 to 3 , Figures 1 to 3 In one embodiment of the present invention, the refrigeration system 5 includes an intake fan. The intake fan is used to facilitate the entry of cold air from the evaporator chamber 502 into the air duct 108 through the air inlet 1081. An intake fan with adjustable speed can be selected; the higher the speed of the intake fan, the more cold air enters the air duct 108 from the evaporator chamber 502 through the air inlet 1081 per unit time.

[0105] Reference Figure 3 An embodiment of the present invention also provides a control method for an ice-making apparatus 1000. The control method may include the following steps.

[0106] S1: The control drive device 6 drives the ice-making rod 201 to rotate to the first position. When the ice-making rod 201 is in the first position, the ice-making rod 201 is at least partially immersed in the water in the water supply chamber 301 to form ice 12 on the ice-making rod 201.

[0107] S2: When the ice 12 on the ice-making rod 201 is completed, the control drive device 6 drives the ice-making rod 201 to rotate to the second position. During the process of the ice-making rod 201 rotating from the first position to the second position, the ice 12 on the ice-making rod 201 falls off under the action of the ice-removing component 4.

[0108] The specific configuration of the drive device 6, water supply chamber 301, ice-making rod 201, and de-icing component 4 can be as described above. The ice-making rod 201 can be set on the rotating component 1 as described above. The drive device 6 drives the ice-making rod 201 to rotate by driving the rotating component 1.

[0109] The first position can be the position where the ice-making rod 201 on the rotating part 1 is facing directly downwards, in which the ice-making rod 201 is at least partially immersed in the water supply chamber 301 below. The second position can be the position where the ice-making rod 201 has rotated a specific angle from the first position along the rotation direction 105. For example, the second position can refer to the position where the ice-making rod 201 has rotated 360 degrees from the first position along the rotation direction 105. During the process of the ice-making rod 201 rotating 360 degrees from the first position to the second position, the ice-making rod 201, after ice making is completed, first carries the ice 12 out of the water supply chamber 301 from the rod exit 3052, and then passes through the de-icing part 4. Under the action of the de-icing part 4, the ice is removed, and the ice-removed ice-making rod 201 re-enters the water supply chamber 301 from the rod inlet 3051 to start a new round of ice making.

[0110] Reference Figure 3 In one embodiment of the present invention, step S2, "when the ice 12 on the ice-making rod 201 is made", may specifically include the following steps.

[0111] S11: Obtain the temperature of ice chamber 8, and connect ice rod 201 to the cooling capacity of ice chamber 8.

[0112] S12: Obtain the water level in water supply room 301.

[0113] S13: When the ice-making rod 201 is in the first position, and the temperature of the ice-making chamber 8 is less than or equal to the preset ice-making temperature, and the water level in the water supply chamber 301 is higher than or equal to the preset water supply level, the timer is controlled to start counting.

[0114] S14: When the timer reaches the preset ice-making time, the ice-making rod 201 completes the ice-making process 12.

[0115] The ice-making device 1000 may include a temperature sensor disposed within the ice-making chamber 8, through which the temperature of the ice-making chamber 8 can be obtained. The ice-making device 1000 may include a water level sensor disposed within the water supply chamber 301, through which the water level of the water supply chamber 301 can be obtained.

[0116] The connection between the ice-making rod 201 and the ice-making chamber 8 means that heat exchange can occur between them. As mentioned above, when the ice-making rod 201 rotates into the ice-making chamber 8, it can directly exchange heat with the chamber. When the ice-making rod 201 rotates into the water supply chamber 301, it can also indirectly exchange heat with the chamber through the rotating component 1. Of course, in other embodiments, the design of the refrigeration system 5 supplying cooling to the ice-making rod 201 and the ice-making chamber 8 through the rotating component 1 can be omitted. Instead, the refrigeration system 5 can directly supply cooling to the ice-making chamber 8 through direct cooling or air cooling, and the ice-making chamber 8 can then supply cooling to the ice-making rod 201.

[0117] Since the temperature of the ice-making chamber 8 has a significant impact on the storage, hardening, and maintenance of the temperature of the ice-making rod 201 of ice 12, it is necessary to monitor the temperature of the ice-making chamber 8. The timing of ice-making on the ice-making rod 201 should only begin when the temperature of the ice-making chamber 8 reaches the preset ice-making temperature, thus ensuring the quality of the ice 12 formed on the ice-making rod 201. The preset ice-making temperature can be pre-set by the designer, for example, -18℃.

[0118] The water level in the water supply chamber 301 also has a significant impact on the quality of the ice 12 formed on the ice-making rod 201. Therefore, it is necessary to monitor the water level in the water supply chamber 301 and ensure that the timing of ice-making time on the ice-making rod 201 starts when the water level in the water supply chamber 301 reaches the preset water supply level, so as to ensure the quality of the ice 12 formed on the ice-making rod 201.

[0119] In one embodiment of the present invention, the control method may further include the following steps:

[0120] S21: If the first size ice 12 is to be made, the first size ice 12 on the ice-making rod 201 will be made when the timer reaches the first preset ice-making time.

[0121] S22: If a second-sized ice 12 is to be made, the second-sized ice 12 will be made on the ice-making rod 201 when the timer reaches the second preset ice-making time. The first size is smaller than the second size, and the first preset ice-making time is smaller than the second preset ice-making time.

[0122] The longer the ice-making time of the ice-making rod 201 in the water supply chamber 301, the larger the size of the ice 12 formed on it. Therefore, the size of the ice 12 formed on the ice-making rod 201 can be controlled by controlling the ice-making time, thereby realizing the production of ice blocks of various sizes and better meeting the needs of users.

[0123] The ice-making device 1000 may include an interactive module for acquiring user input information, which can determine the size of the ice 12 to be made based on the user input information. When the user inputs information indicating the production of ice 12 of a first size, the first preset ice-making time is taken as the completion time for making ice 12 on the ice-making rod 201. When the user inputs information indicating the production of ice 12 of a second size, the second preset ice-making time is taken as the completion time for making ice 12 on the ice-making rod 201.

[0124] Reference Figure 6 In one embodiment of the present invention, step S2, "controlling the driving device 6 to drive the ice-making rod 201 to rotate", may specifically include the following steps.

[0125] S30: Obtain the position detection signal from the position detection device 11, and control the drive device 6 to drive the ice-making rod 201 to rotate according to the change of the position detection signal. The position detection device may include a first detection element 1101 and a second detection element 1102 that are configured in cooperation. The first detection element 1101 is fixedly disposed on one side of the rotation axis 104 of the rotating element 1, and the second detection element 1102 rotates synchronously with the ice-making element 2 around the rotation axis 104.

[0126] Specifically, the first detection element 1101 can be a Hall sensor 1101, and the second detection element 1102 can be a magnet.

[0127] Both the magnet and the ice-making rod 201 can be mounted on the rotating component 1, or the magnet can be mounted on the ice-making rod 201. When multiple ice-making rods 201 are arranged along the circumferential direction 102 on the rotating component 1, each ice-making rod 201 at each angle can be equipped with a corresponding magnet. For example, as mentioned above, the rotating component 1 can be equipped with a first ice-making rod 202, a second ice-making rod 203, and a third ice-making rod 204 spaced 120° apart. Then the magnet can include a first magnet 11021 corresponding to the first ice-making rod 202, a second magnet 11022 corresponding to the second ice-making rod 203, and a third magnet 11023 corresponding to the third ice-making rod 204.

[0128] A single Hall sensor 1101 may be provided, and it may be located directly below the rotation axis 104 of the rotating member 1. The Hall sensor 1101 may be installed on the wall of the ice-making chamber 8 or the water supply chamber 301. When the rotating member 1 rotates to the point where the magnet is directly opposite or away from the Hall sensor 1101, the signal of the Hall sensor 1101 will change. Therefore, the position of the ice-making rod 201 corresponding to the magnet can be determined by the signal change of the Hall sensor 1101, and the drive device 6 can be controlled.

[0129] Reference Figure 8 , Figure 6 and Figure 8In one embodiment of the present invention, the control method may include the following steps.

[0130] S41: Obtain the water temperature of the water storage chamber 302, which is used to supply water to the water supply chamber 301.

[0131] S42: The opening of the air outlet damper is controlled according to the water temperature of the stored water. The water temperature of the stored water is positively correlated with the opening of the air outlet damper. The air outlet damper is used to adjust the amount of cold air blown from the air outlet 1082 to the water storage chamber 302.

[0132] S43: When the water temperature in the storage tank is less than or equal to the preset water temperature, the air outlet damper is completely closed.

[0133] The ice-making device 1000 may include a temperature sensor for acquiring the temperature of the water storage chamber 302. By controlling the opening of the air outlet damper, the opening of the air outlet 1082 can be adjusted to control the volume of cold air blown from the air outlet 1082 to the water storage chamber 302, thereby reducing the temperature of the water in the water storage chamber 302 and controlling the cooling rate of the water in the water storage chamber 302. Through the circulation of water in the water storage chamber 302 and the water supply chamber 301, the temperature of the water in the water supply chamber 301 can be reduced, improving ice-making efficiency and preventing the water in the water storage chamber 302 from becoming too cold, thus preventing the water in the water storage chamber 302 or the water supply chamber 301 from freezing. The preset water storage temperature can be 0°C.

[0134] Reference Figure 4 and Figure 3 In one embodiment of the present invention, the control method may include the following steps.

[0135] S51: Obtain the water temperature supplied to water supply room 301.

[0136] S52: When the water supply temperature is lower than the preset water supply temperature, control the water supply heater used to heat the water supply chamber 301 to start.

[0137] S53: Obtain the water temperature of the water storage chamber 302, which is used to supply water to the water supply chamber 301.

[0138] S54: When the water temperature in the storage chamber is lower than the preset water temperature, the water heater used to heat the water storage chamber 302 is activated.

[0139] The ice-making device 1000 may include a temperature sensor for acquiring the temperature of the water supply chamber 301. The water supply heater and water storage heater may be heating wires, etc. The preset water supply temperature may be 0°C. By detecting the temperatures of the water storage chamber 302 and the water supply chamber 301, the water temperatures in the water storage chamber 302 and the water supply chamber 301 can be controlled within an appropriate temperature range to ensure ice-making efficiency. By installing heaters, freezing of the water in the water storage chamber 302 or the water supply chamber 301 can be prevented.

[0140] ReferenceFigure 6 In one embodiment of the present invention, the control method may include the following steps.

[0141] S61: Obtain the water level in water supply room 301.

[0142] S62: When the water supply level is lower than the preset water supply level, control the water supply pump to run at the first preset speed. The water supply pump is used to transport water in the water storage chamber 302 to the water supply chamber 301 through the water supply pipe 303.

[0143] S63: When the water supply level is greater than or equal to the preset water supply level, the water supply pump is controlled to run at a second preset speed. The second preset speed is less than the first preset speed. A return water pipe 304 is provided between the water storage chamber 302 and the water supply chamber 301. The return water pipe 304 is used to allow water in the water supply chamber 301 that is higher than the preset water supply level to flow back to the water storage chamber 302.

[0144] When the water level in the water supply chamber 301 is lower than the preset water supply level, the water supply pump is controlled to run at a higher speed to quickly replenish water in the water supply chamber 301 and ensure that the water level in the water supply chamber 301 reaches the preset standard. When the water level is greater than or equal to the preset water supply level, the water supply pump is controlled to run at a lower speed, which enables water flow between the water storage chamber 302 and the water supply chamber 301 through the water supply pipe 303 and the return water pipe 304. This promotes the flow of water in the water supply chamber 301, thereby making the ice 12 generated on the ice-making rod 201 transparent ice 12, improving the transparency and quality of the ice, and realizing the production of transparent bullet ice 12.

[0145] Reference Figures 1 to 3 and Figure 1 In one embodiment of the present invention, the control method may include the following steps.

[0146] S70: Control the air inlet damper to open to its maximum opening, and control the air inlet fan to operate at its maximum speed. The ice-making device 1000 includes a rotating component 1, with an air duct 108 formed inside the rotating component 1. An ice-making component 2 is disposed on the rotating component 1. The drive device 6 drives the rotating component 1 to rotate, thereby driving the ice-making component 2 to rotate. The air inlet damper is used to regulate the amount of cold air entering the air duct 108 from the evaporator chamber 502 through the air inlet 1081. The air inlet fan is used to promote the entry of cold air from the evaporator chamber 502 into the air duct 108 through the air inlet 1081. This configuration promotes the entry of cold air from the evaporator chamber 502 into the air duct 108, improving cooling efficiency and ice-making efficiency.

[0147] Reference Figure 6 In one embodiment of the present invention, step S2, "controlling the driving device 6 to drive the ice-making rod 201 to rotate to the second position", may further include the following steps.

[0148] S81: Control drive device 6 drives ice-making rod 201 to rotate to the third position. The third position is between the first position and the second position. When ice-making rod 201 is in the third position, ice-making rod 201 is located in ice-making chamber 8.

[0149] S82: When the ice-making rod 201 stays in the third position for a preset time, the control drive device 6 drives the ice-making rod 201 to rotate to the second position. During the process of the ice-making rod 201 rotating from the third position to the second position, the ice 12 on the ice-making rod 201 falls off under the action of the ice-removing component 4.

[0150] By keeping the ice-carrying rod 201 in the ice-making chamber 8 for a period of time before de-icing, the ice 12 can be further cooled and hardened before de-icing. This ensures that the surface moisture of the ice is completely frozen, preventing liquid water from remaining on the surface of the ice after de-icing. It also ensures that the ice is dry, preventing the de-iced ice 12 from being wet, and preventing ice from sticking together in the ice storage box 9. The fully cooled ice not only has completely frozen surface moisture, but also has a denser and harder internal structure, resulting in higher quality.

[0151] The third position can be a position where the ice-making rod 201 rotates a specific angle from the first position along the rotation direction 105, and the angle from the first position to the third position is smaller than the angle from the first position to the second position. For example, the third position can be a position where the ice-making rod 201 rotates 120° from the first position along the rotation direction 105. The de-icing component 4 can be located at a position where the ice-making rod 201 rotates 240° from the first position along the rotation direction 105.

[0152] Reference Figure 6 In one embodiment of the present invention, the control method may include the following steps.

[0153] S90: When the ice 12 on the ice-making rod 201 is made, the rod heater used to heat the ice-making rod 201 is started.

[0154] The ice-making device 1000 may include a rod heater disposed within the ice-making rod 201. The rod heater may be a heating wire or the like. By heating the ice-making rod 201, it is easier for the ice 12 on the ice-making rod 201 to fall off.

[0155] Reference Figure 6 One embodiment of the present invention also provides a refrigeration device 2000. The refrigeration device 2000 may include a housing 2001, a storage compartment 2002 formed within the housing 2001, and a door 2003 for opening and closing the storage compartment 2002. The refrigeration device 2000 may also include an ice-making device 1000 as described in any of the above embodiments. The ice-making device 1000 may be disposed in the housing 2001, the storage compartment 2002, or the door 2003.

[0156] In one embodiment of the present invention, the refrigeration device 2000 may further include a memory and a processor. The memory stores a computer program that can run on the processor. When the processor executes the computer program, it implements the steps in the control method of the ice-making device 1000 in any of the above embodiments.

[0157] Reference ​ In one embodiment of the present invention, the ice-making device 1000 can be disposed in the storage chamber 2002. The evaporator chamber 502 of the refrigeration system 5 can be used to supply cooling to the storage chamber 2002. The evaporator chamber 502 can be disposed at the rear of the storage chamber 2002. By adopting the design scheme of the present invention, not only can the refrigeration system 5 supply cooling to both the storage chamber 2002 and the ice-making device 1000 simultaneously, but the cleanliness of the ice-making chamber 8 and the ice 12 can also be ensured.

[0158] Reference ​ In one embodiment of the present invention, the storage compartment 2002 may include a first storage compartment 20021 and a second storage compartment 20022 located below the first storage compartment 20021. The ice-making compartment 8, the water supply compartment 301, and the water storage compartment 302 may all be disposed within the first storage compartment 20021. The ice storage box 9 may be disposed within the second storage compartment 20022. The first storage compartment 20021 may be a refrigerator compartment. The second storage compartment 20022 may be a freezer compartment. The refrigeration system 5 may include a refrigerator evaporator compartment 502 for supplying cooling to the refrigerator compartment and a refrigerator evaporator 503 disposed within the refrigerator evaporator compartment 502. The refrigeration system 5 may include a freezer evaporator compartment for supplying cooling to the freezer compartment and a freezer evaporator disposed within the freezer compartment. The refrigerator evaporator compartment may be connected to the air duct 108 within the rotating component 1 to achieve air-cooled cooling of the rotating component 1 from the refrigerator evaporator compartment 502. A portion of the evaporator tubes of the refrigeration evaporator 503 can be placed within the receiving cavity 106 of the rotating component 1 to achieve direct cooling from the refrigeration evaporator 503 to the rotating component 1. The refrigeration equipment 2000 of the present invention can be a refrigerator, freezer, etc.

[0159] In summary, by adopting the technical solution of the present invention, the ice-making rod 201 can be periodically immersed in the water in the water supply chamber 301 through rotation. This dynamic immersion allows each ice-making rod 201 to obtain a certain amount of water within a specific time, thereby forming ice 12. This helps to precisely control the size of the ice blocks formed on the ice-making rod 201, improving the quality of the ice blocks. Furthermore, the ice-making rod 201 can periodically pass through the de-icing component 4. Through rotation, the ice-making rod 201 and the de-icing component 4 come into periodic contact, allowing the ice blocks to be thawed at appropriate times and under appropriate conditions. The downward detachment design ensures a smooth and efficient de-icing process. The ice-making and de-icing process of the ice-making rod 201 is completed by rotation. It can allow the ice-making and de-icing processes on the same ice-making rod 201 to be carried out alternately, and it can also allow the ice-making and de-icing processes on different ice-making rods 201 to be carried out simultaneously when there are multiple ice-making rods 201. This achieves continuous ice-making and improves production efficiency, increases the utilization rate of the equipment, enables the production of bullet ice 12, reduces energy consumption, and has a compact structure that reduces the space occupied. By setting an air duct 108 inside the rotating part 1 and supplying cold air to the evaporator chamber 502, the refrigeration system 5 can provide air-cooled cooling to the rotating part 1. Since the air duct 108 is set inside the rotating part 1 and directly connected to the evaporator chamber 502, the air in the air duct 108 and the evaporator chamber 502 can be prevented from communicating with the ice-making chamber 8, ensuring the cleanliness of the refrigeration chamber and preventing odors, bacteria and other pollutants from contaminating the ice-making chamber 8. It can also reduce the weight of the rotating part 1 and ensure the uniformity of the temperature of the circumferential wall 107 of the rotating part 1.
