An ice-making pipe is attached to the outer wall surface of the ice-making bucket. An ice-making motor is also provided at the top of the ice-making bucket to make it rotate relative to the ice-making pipe. A heat-conducting structure made of a heat-conducting material is further provided between the ice-making bucket and the ice-making pipe. One side of the heat-conducting structure is rotatably connected to the ice-making bucket, and the other side of the heat-conducting structure is fixedly connected to the ice-making pipe.

Description

Technical Field

[0001] The invention relates to the technical field of ice making equipment, in particular to a compact ice making and water drinking machine. Background Art

[0002] An ice dispenser is a convenient device that combines refrigeration, ice-making, and water-drinking functions, commonly used in homes, offices, and commercial spaces. Its refrigeration system quickly cools tap water to a suitable drinking temperature and can produce ice cubes on demand, providing users with a refreshing drinking experience. An ice dispenser typically consists of a water tank, refrigeration system, filter, and control panel. Its simplicity, convenience, energy efficiency, environmental protection, and safety have made it widely popular. The refrigeration system rapidly cools the tap water in the tank to a suitable drinking temperature, ensuring users have access to refreshing drinking water at any time. The refrigeration system is the core component of an ice dispenser and typically utilizes compressor refrigeration technology. This system works through a circulation system to quickly cool the water in the tank to the desired temperature while also producing ice cubes. Users can adjust the water temperature and ice-making function via the control panel to meet their needs. The refrigeration system is highly efficient and energy-efficient, ensuring long-term stability and reliability. Ice dispensers are often equipped with a filter to effectively remove impurities and odors from the water, improving the quality of the drinking water. Filters typically utilize multi-stage filtration technology, such as PP cotton and activated carbon, to effectively remove harmful substances from water, ensuring healthy and safe drinking water. Generally speaking, existing ice water dispensers are convenient devices that combine refrigeration and filtration functions, providing users with a refreshing and healthy drinking experience. Their simple operation, high energy efficiency, and health and safety features have made them widely used in various settings, including homes, offices, and commercial spaces, and have been well-received by users.

[0003] However, existing ice-making and water-dispensing machines are typically larger than traditional water dispensers due to their built-in ice-making structures, such as a compressor and an ice box for storing ice cubes. Therefore, these ice-making and water-dispensing machines are usually vertical and placed on the ground for use. This makes them unusable on desktops or storage platforms, and in some confined environments, there is insufficient space for such machines. Furthermore, these ice-making and water-dispensing machines are unable to dispense ice cubes individually during use, and the ice cubes produced contain a large number of bubbles, which reduces their transparency. In some applications where high transparency is required, such as ice cubes used for cocktails in bars, the ice cubes produced by these traditional ice-making and water-dispensing machines cannot be used in these situations. Furthermore, these ice-making and water-dispensing machines typically pre-make ice and then use an ice box to store the ice cubes. However, the temperature inside the ice box is generally not high enough to store the ice cubes for a long time, and some of the ice cubes may melt. Summary of the Invention

Technical problem to be solved: In view of the deficiencies of the prior art, the present invention provides a compact ice-making drinking machine, which has no ice storage structure inside the device, adopts real-time ice-making, can be used in places with limited space, and has the advantages of high transparency of the produced ice cubes, solving the problems of the existing ice-making drinking machines with large volume due to the built-in ice storage structure and low transparency of the produced ice cubes.

[0005] 2. Technical solution: To achieve the purpose of having no ice storage structure inside the device, adopting real-time ice-making, being able to be used in places with limited space, and having high transparency of the produced ice cubes, the present invention provides the following technical solution: A compact ice-making drinking machine includes an ice-making bucket, on the outer wall surface of which an ice-making tube is attached. At the top of the ice-making bucket, there is a water injection port, and at the top of the ice-making bucket, there is also an ice-making motor that causes it to rotate relative to the ice-making tube.

[0007] Preferably, the ice-making bucket and the heat-conducting structure are in a cylindrical shape, and the ice-making tube is fixedly wound in a spiral shape outside the heat-conducting structure.

[0008] Preferably, the ice-making motor is fixedly connected with a fixing plate. The motor shaft of the ice-making motor is fixedly connected to the top end surface of the ice-making bucket. The heat-conducting structure is fixedly connected between the fixing plate. A circular rotating collar is fixedly arranged on the fixing plate. A number of fixing plates are arranged in an array along the circumference of the rotating collar. A fixed collar is arranged on the rotating collar, and the fixed collar and the rotating collar are rotatably connected. A transmission belt is also arranged on the rotating collar, and the transmission belt is also connected to a transmission motor. An evaporation tube 1 is fixedly arranged inside the fixed collar. The evaporation tube 1 is connected to a compressor. A cooling turntable is rotatably arranged at the bottom of the evaporation tube 1. The inside of the cooling turntable is connected to the inside of the evaporation tube 1. A number of evaporation tubes 2 connected to the inside of the cooling turntable are arranged along the circumference of the cooling turntable. The evaporation tubes 2 penetrate through the rotating collar and are connected to the ice-making tube.

[0009] Preferably, a control valve is arranged on the evaporation tube 2.

[0010] Preferably, an anti - detachment structure is further provided between the driving motor and the rotating collar.

[0011] Preferably, the fixed collar is fixedly arranged inside the water dispenser. A support rod is rotatably arranged at the bottom of the rotating collar. The bottom of the support rod is arranged inside the water dispenser. A return flow tray is arranged on the support rod. A drain pipe is arranged on the return flow tray. The return flow tray is coaxially arranged with the rotating collar. The height of the return flow tray is less than the height of the ice - making bucket.

[0012] Preferably, a notch is further opened on the return flow tray. An ice outlet pipe is arranged at the notch position. The bottom of the ice outlet pipe is connected to the ice outlet of the water dispenser. A water - absorbing cotton with a diameter smaller than that of the ice outlet pipe is coaxially arranged inside the ice outlet pipe. A water - absorbing collar is coaxially arranged on the ice outlet pipe. The inner side of the water - absorbing collar is connected to the water - absorbing cotton. A negative - pressure pipe is arranged on the water - absorbing collar. A vacuum pump is arranged on the negative - pressure pipe.

[0013] Preferably, an inverted funnel structure is further arranged on the ice outlet pipe.

[0014] Preferably, a water injection pipe is further arranged above the water injection port. A magnetic ring is arranged at the connection position of the water injection port and the water injection pipe.

[0015] (III) Beneficial effects: Compared with the prior art, the present invention provides a compact ice - making water dispenser, which has the following beneficial effects:

[0016] 1. In this compact ice - making water dispenser, through the combined use of the ice - making bucket structure, the ice - making motor structure, and the ice - making pipe structure, compared with the traditional ice - making water dispenser that can only produce ice cubes with lower transparency, this compact ice - making water dispenser makes the water inside rotate and form a secondary flow by using the rotation of the ice - making bucket. This secondary flow and the rotation of the water generate multiple stirrings in different directions. The stirring will quickly bring the bubbles in the water to the liquid surface and release them. Most of the bubbles in the water are effectively removed. In this way, the gas content in the ice cubes produced by the ice - making bucket will be reduced, and the transparency of the ice cubes will be improved, making the ice cubes look clearer and more transparent. At the same time, this phenomenon can increase the flow area of the water and the surface of the ice - making bucket, thereby increasing the heat transfer efficiency, accelerating the condensation speed of the ice cubes, improving the ice - making efficiency, and the improvement of the ice - making rate enables the device to produce ice and discharge ice at the same time.

[0017] 2. This compact ice-making water dispenser, through the combined use of an ice-making bucket structure, a fixed plate structure, and a rotating collar structure, compared with traditional ice-making water dispensers, requires an additional large-sized ice storage structure. At the same time, this structure makes it impossible to dispense ice one by one. Moreover, since the ice storage structure usually has poor heat preservation, a large amount of water melts on the surface of the ice, affecting the use effect of the ice. However, in this compact ice-making water dispenser, since each ice-making bucket is independent of each other, this structure can simultaneously produce multiple ice cubes and can dispense ice one by one. At the same time, there is no need for an additional ice storage structure, thus reducing the overall volume of the ice-making module. And in this structure, after the ice cubes are formed, since the ice cubes are always in a separate low-temperature ice-making bucket, the melting rate of the ice cubes is greatly reduced, the generation of water melting is reduced, and at the same time, the phenomenon of connection between multiple ice cubes that is prone to occur in traditional devices can be avoided.

[0018] 3. This compact ice-making water dispenser, through the combined use of an ice-making bucket structure, an ice outlet pipe structure, and a water-absorbing cotton structure, compared with traditional ice-making water dispensers, the ice cubes are prone to water melting on the surface during storage, affecting the use experience of the ice. However, in this compact ice-making water dispenser during the ice outlet process, the water melting attached to the surface will be absorbed by the water-absorbing cotton installed inside the ice outlet pipe. And the water melting absorbed by the water-absorbing sponge is sucked out and discharged through the vacuum pump to generate negative pressure in the negative pressure pipe. Through this structure, the water melting on the surface of the ice cubes can be effectively reduced, thus avoiding the dilution of the liquid caused by water melting during the use of the ice cubes.

Detailed implementation manners

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0038] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 ,a compact ice-making drinking fountain, comprising an ice-making bucket 1, an ice-making tube 2 is attached to the outer wall surface of the ice-making bucket 1, a water injection port 3 is arranged at the top of the ice-making bucket 1, and an ice-making motor 4 for rotating the ice-making bucket 1 relative to the ice-making tube 2 is further arranged at the top of the ice-making bucket 1. When the ice-making bucket 1 rotates, the liquid inside the ice-making bucket 1 rotates with it and forms ice cubes. Among them, the function of designing the ice-making motor 4 is to drive the rotation of the ice-making bucket 1, so as to realize the ice-making process. In the compact ice-making drinking fountain, the ice-making bucket 1 rotates by starting the ice-making motor 4, so that the liquid in the bucket rotates in a circular motion and forms ice cubes under the action of the heat conduction structure 5. The function of the ice-making motor 4 is to provide power so that the ice-making bucket 1 can rotate, so as to achieve the purpose of ice-making. Specifically, the ice-making motor 4 is fixedly connected to the top end surface of the ice-making bucket 1 through a motor shaft. When the motor starts, the motor shaft rotates to drive the ice-making bucket 1 to rotate. During the rotation of the ice-making bucket 1, the internal liquid is affected by the centrifugal force and generates a flow similar to circular motion, thereby promoting the formation of ice cubes. Please refer to Figure 1 、 Figure 9 、 Figure 12 and Figure 17 ,a heat conduction structure 5 made of a heat conduction material is further arranged between the ice-making bucket 1 and the ice-making tube 2. The heat conduction material is copper, aluminum or a metal matrix composite material such as copper-diamond, aluminum-silicon carbide and other composite materials. One side of the heat conduction structure 5 is rotatably connected to the ice-making bucket 1, and the other side of the heat conduction structure 5 is fixedly connected to the ice-making tube 2. The function of designing the heat conduction structure 5 is to optimize the heat conduction efficiency in the ice-making process, thereby accelerating the speed of ice cube formation and ensuring the stability and efficiency of the entire ice-making system. Through the heat conduction structure 5, the cold quantity inside the ice-making bucket 1 can be effectively conducted to the ice-making tube 2, ensuring effective contact between the ice-making tube 2 and the ice-making bucket 1, thereby maintaining the stability during the ice-making process and avoiding the situation of poor ice-making effect or damage to the structure of the ice-making tube 2 caused by poor contact. At the same time, the rotatable connection between the heat conduction structure 5 and the ice-making bucket 1 can ensure that the ice-making bucket 1 can still be cooled by the ice-making tube 2 during the rotation process. Please refer to Figure 9, the ice-making bucket 1 and the heat-conducting structure 5 are cylindrical in shape, and the ice-making tube 2 is spirally fixed and wound around the outside of the heat-conducting structure 5. The cylindrical shapes of the ice-making bucket 1 and the heat-conducting structure 5 are mainly to maximize the efficiency and uniformity during the ice-making process. The cylindrical ice-making bucket 1 and heat-conducting structure 5 can ensure the uniform distribution of the internal liquid or ice cubes during rotation. This can make the cooling effect more uniform throughout the ice-making process, avoiding the situation where some areas are over-cooled while some other areas have a higher temperature. And the cylindrical structure can maximize the contact area, thereby enhancing the heat conduction efficiency between the heat-conducting structure 5 and the ice-making bucket 1. This helps to quickly transfer the cold in the ice-making bucket 1 to the ice-making tube 2, accelerating the ice formation process. At the same time, the cylindrical structure is more stable during rotation, reducing the possibility of vibration or uneven rotation caused by irregular shapes. This can ensure the stability and reliability of the ice-making process. The cylindrical structure is easier to integrate into a compact ice-making water dispenser compared to other shapes, which can maximize space savings and improve the compactness and portability of the device.

[0039] Please refer to Figure 1 , Figure 2 , Figure 9 , Figure 13 , Figure 14 and Figure 15 , a rotatable bottom plate 6 is provided at the bottom of the ice-making bucket 1 such that it can rotate and open relative to the ice-making bucket 1. Above the rotatable bottom plate 6, a bottom plate motor 7 for driving its rotation is provided. The motor shaft of the bottom plate motor 7 is fixedly connected to the rotatable bottom plate 6, and the bottom plate motor 7 is fixed to the side of the heat-conducting structure 5. When the bottom plate motor 7 drives the rotatable bottom plate 6 to rotate and open, the ice-making bucket 1 is in the ice-dropping state. The main purpose of designing the rotatable bottom plate 6 is to facilitate the removal of the ice cubes formed in the ice-making bucket 1 from the ice-making bucket 1, realizing the ice-discharging function. The rotatable bottom plate 6 can open the bottom of the ice-making bucket 1, allowing the formed ice cubes to easily fall off from the ice-making bucket 1 and enter the ice-discharging tube 21, facilitating the user to obtain the ice. And by automatically opening the bottom of the ice-making bucket 1, the automatic ice-discharging function can be realized, eliminating the need for manual operation by the user, saving time and labor costs, and improving the efficiency of the entire ice-making system. At the same time, when the bottom of the ice-making bucket 1 is opened, the ice cubes can slide out freely, avoiding the adhesion between ice cubes, ensuring the independence of each ice cube, and improving the uniformity and reliability of ice discharge.

[0040] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5, the ice-making motor 4 is fixedly connected to a fixing plate 8. The motor shaft of the ice-making motor 4 is fixedly connected to the top surface of the ice-making bucket 1. The heat conduction structure 5 is fixedly connected to the fixing plate 8. The main purpose of designing the fixing plate 8 is to fix the ice-making motor 4 and the heat conduction structure 5, ensure that they can be firmly connected together, and maintain a relatively static position during the ice-making process. And the fixing plate 8 can effectively reduce the possibility of the ice maker malfunctioning during operation. If the ice-making motor 4 or the heat conduction structure 5 moves or swings, it may cause wear or damage to the components, thus affecting the performance and reliability of the ice maker. Through the design of the fixing plate 8, the incidence of these faults can be reduced, and the service life of the ice maker can be extended. At the same time, the design of the fixing plate 8 makes the maintenance and repair of the ice maker simpler and more convenient. If maintenance or replacement of the ice-making motor 4 or the heat conduction structure 5 is required, it only needs to release its fixation on the fixing plate 8, without the need to disassemble the entire ice maker, saving maintenance time and costs. A circular rotating collar 9 is fixedly arranged on the fixing plate 8. A number of fixing plates 8 are arranged in an array along the circumferential direction of the rotating collar 9. A fixing collar 10 is arranged on the rotating collar 9. The fixing collar 10 is rotatably connected to the rotating collar 9. A transmission belt 11 is also arranged on the rotating collar 9. The transmission belt 11 is also connected to a transmission motor 12. An anti-disengagement structure 17 is also arranged between the transmission motor 12 and the rotating collar 9. The anti-disengagement structure 17 ensures that the transmission belt 11 can be tightly connected and drive the rotating collar 9, avoiding the situation of falling off or loosening during high-speed rotation. The rotating collar 9 is driven by the transmission motor 12 to rotate by a fixed angle, so that the ice-making bucket 1 that has completed ice-making inside moves above the ice outlet pipe 21 in turn for ice discharging. Please participate Figure 1 and Figure 16, an evaporation pipe 13 is fixedly arranged inside the fixed collar 10. The evaporation pipe 13 is connected to a compressor. A cooling turntable 15 is rotatably arranged at the bottom of the evaporation pipe 13. The inside of the cooling turntable 15 is communicated with the inside of the evaporation pipe 13. A plurality of evaporation pipes 14 communicated with the inside of the cooling turntable 15 are arranged along the circumferential direction of the cooling turntable 15. The evaporation pipes 14 penetrate through the rotating collar 9 and are communicated with the ice-making pipe 2. By arranging the cooling turntable 15, relative rotation can occur between it and the evaporation pipe 13. When the rotating collar 9 rotates, the evaporation pipes arranged on the cooling turntable 15 can rotate together with the rotating collar 9. Such a design can ensure that the cooling effect of the evaporation pipes 14 can completely cover the ice-making pipe 2, improving the ice-making efficiency and quality. A control valve 16 is arranged on the evaporation pipe 14. The purpose of arranging the control valve 16 is to adjust the flow rate of the evaporation pipe 14, thereby controlling the ice-making speed and quality during the ice-making process. The design of the control valve 16 can achieve the following functions. Through the control valve 16, the flow rate of the ice-making material, usually water, in the evaporation pipe 14 can be adjusted, thereby adjusting the speed during the ice-making process. According to needs, the flow rate can be increased or decreased to make the ice-making speed adapt to different requirements. By precisely controlling the flow rate, it can be ensured that the condensation and crystallization processes of water during the ice-making process are fully carried out, thereby obtaining more uniform and stronger ice cubes and improving the ice-making quality. At the same time, the design of the control valve 16 can make the ice-making process more stable. By ensuring the stability of the flow rate, the fluctuations and unstable factors during the ice-making process can be reduced, thereby improving the stability and reliability of the system. Among them, the ice-making pipe 2, the evaporation pipe 13 and the evaporation pipe 14 are internally provided with a reflux structure. The reflux structure can recycle the cooling medium. By redirecting the cooling medium back into the compressor to complete the cycle.

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, the fixed collar 10 is fixedly arranged inside the water dispenser. A support rod 18 is also rotatably arranged at the bottom of the rotating collar 9. The bottom of the support rod 18 is arranged inside the water dispenser. The arrangement of the support rod 18 can provide additional support to ensure the stability of the ice-making bucket 1 and other rotating components. During the ice-making process, the rotational movement of the ice-making bucket 1 and other components may be subject to certain forces and vibrations. The presence of the support rod 18 can reduce the impact of these forces on the system structure and maintain the stability and balance of the entire system. The support rod 18 can help keep the rotating components properly aligned, ensuring that they maintain a stable position and direction during operation. This is crucial for the rotational movement of components such as the ice-making bucket 1 and the rotating bottom plate 6, ensuring the smooth progress of the ice-making process. At the same time, by providing additional support, the support rod 18 can reduce the vibration and friction between the rotating components inside the system, thereby reducing the noise level generated during the operation of the entire system. This helps improve the user experience and makes the ice-making water dispenser quieter during operation. Moreover, the presence of the support rod 18 can increase the overall stability of the system, reduce the possibility of accidental swaying or tilting, and improve the safety of the system. Especially when the ice maker is operating, ensuring the stability of the system is crucial for preventing accidents. A return pan 19 is also arranged on the support rod 18. A drain pipe 20 is arranged on the return pan 19. The return pan 19 is coaxially arranged with the rotating collar 9. The height of the return pan 19 is less than the height of the ice-making bucket 1. During the process of filling or rotating the ice-making bucket 1, if liquid overflows, the return pan 19 will collect the overflowed liquid and then discharge it from the system through the drain pipe 20. This can ensure that the system remains clean and prevent waste or pollution caused by liquid overflow. This design not only improves the efficiency and stability of the system but also enhances the user experience because users don't have to worry about liquid overflow during the ice-making process and can thus use the ice-making water dispenser more conveniently.

[0042] Please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6, there is also a notch on the return flow tray 19, and an ice outlet pipe 21 is arranged at the notch position. The design of the notch is mainly for installing the ice outlet pipe 21. A reverse funnel structure is also arranged on the ice outlet pipe 21. The reverse funnel structure can guide the ice cubes to the inlet position of the ice outlet pipe 21, ensuring that the ice cubes smoothly enter the ice outlet pipe 21 and avoiding the situation that the ice cubes deviate from the direction or get stuck during the flowing process. At the same time, the design of the reverse funnel structure can reduce the possibility of the ice outlet pipe 21 being blocked by the ice cubes during the flowing process. By reasonably designing the shape and size of the reverse funnel, the stagnation and accumulation of ice cubes inside the reverse funnel can be avoided, ensuring that the ice cubes can be smoothly discharged. The reverse funnel structure can also play a role in protecting the ice outlet pipe 21. The reverse funnel can serve as a buffer area to reduce the impact on the ice outlet pipe 21 when the ice cubes enter the ice outlet pipe 21, thereby prolonging the service life of the ice outlet pipe 21. The role of the funnel structure in the ice maker is to ensure that the ice cubes can accurately enter the ice outlet pipe 21 and be smoothly discharged, thereby ensuring the normal operation and efficient work of the ice maker. Please refer to Figure 6 , Figure 7 , Figure 8 , the bottom of the ice outlet pipe 21 is connected to the ice outlet of the water dispenser. A water absorption cotton 22 with a diameter smaller than that of the ice outlet pipe 21 is coaxially arranged inside the ice outlet pipe 21. There may be some moisture remaining on the surface of the ice cubes during the production process. Through the absorption of the water absorption cotton 22, the number of water droplets generated when the ice cubes melt in the ice outlet pipe 21 can be reduced, keeping the ice outlet pipe 21 dry. A water absorption sleeve ring 23 is also coaxially arranged on the ice outlet pipe 21. The inner side of the water absorption sleeve ring 23 is connected to the water absorption cotton 22. A negative pressure pipe 24 is also arranged on the water absorption sleeve ring 23, and a vacuum pump 25 is arranged on the negative pressure pipe 24. The main purpose of arranging the negative pressure pipe 24 is to discharge the water in the water absorption cotton 22 that has absorbed the moisture on the surface of the ice cubes through the negative pressure effect, so as to maintain the water absorption performance of the water absorption cotton 22 and the smoothness of the ice outlet pipe 21. When the water absorption cotton 22 absorbs the moisture on the surface of the ice cubes, through the negative pressure effect generated by the negative pressure pipe 24, the moisture in the water absorption cotton 22 can be sucked out and discharged, thereby maintaining the water absorption performance of the water absorption cotton 22. If the moisture in the water absorption cotton 22 cannot be discharged in time, it may lead to the remaining moisture in the water absorption cotton 22, affecting the water absorption effect of the water absorption cotton 22 in the next ice making process, and even causing bacterial growth or peculiar smell. By discharging the moisture in the water absorption cotton 22, the condensation of water droplets inside the ice outlet pipe 21 can be avoided, reducing the possibility of pipeline blockage and bacterial growth. Please refer to Figure 1 and Figure 5 , a water injection pipe 26 is also arranged above the water injection port 3. A magnetic ring is arranged at the connection position of the water injection port 3 and the water injection pipe 26. Arranging the magnetic ring can prevent the problem of mismatch between the water injection port 3 and the water injection pipe 26 caused by the rotation of the ice making bucket 1.

[0043] Working principle: This device is installed on a water dispenser. When in use, the evaporation pipe 13 is connected to the compressor, and the water injection pipe 26 is connected to the water inlet pipe of the water dispenser. When in use, the water injection pipe 26 injects water into the ice-making bucket 1 through the water injection port 3. When the ice-making bucket 1 is full of water, the drive motor 12 drives the rotating collar 9 to rotate through the drive belt 11, thereby causing the fixed plate 8 to rotate, so that the next ice-making bucket 1 that has not been injected with water moves below the water injection pipe 26 for water injection. For the ice-making bucket 1 that is full of water, the control valve 16 is opened at this time to allow the ice-making pipe 2 to cool the ice-making bucket 1. At the same time, the ice-making motor 4 starts to drive the ice-making bucket 1 to rotate. During the rotation of the ice-making bucket 1, a certain frictional force will be generated on the internal water, so that the water will also rotate with the ice-making bucket 1, and the water will gradually freeze into ice cubes during the rotation. When ice cubes are formed inside the ice-making bucket 1, the ice-making bucket 1 moves above the ice discharge pipe 21 at this time. The ice cubes are separated from the ice-making bucket 1 by heating in the refrigeration pipe. Subsequently, the rotating bottom plate 6 is driven to open by the bottom plate motor 7, and the ice cubes fall from the ice-making bucket 1 into the ice discharge pipe 21 and are discharged. The device circulates this process to make ice. At the same time, since there are several fixed plates 8 provided on the rotating collar 9 and each ice-making bucket 1 is independent of each other, this structure can make multiple ice cubes simultaneously and can realize ice discharge one by one without an additional structure for storing ice cubes, thereby reducing the overall volume of the ice-making module. And in this structure, after the ice cubes are formed, since the ice cubes have been in a separate low-temperature ice-making bucket 1 all the time, the melting rate of the ice cubes is greatly reduced, the generation of melted water is reduced, and at the same time, the phenomenon of connection between multiple ice cubes that is likely to occur in traditional devices can be avoided.

[0044] In the above ice-making process, when the ice cubes pass through the ice discharge pipe 21, the melted water attached to their surfaces will be absorbed by the absorbent cotton 22 installed inside the ice discharge pipe 21, and the melted water absorbed by the absorbent sponge is sucked out and discharged by generating negative pressure in the negative pressure pipe 24 through the vacuum pump 25. Through this structure, the melted water on the surface of the ice cubes can be effectively reduced, thereby avoiding the dilution of the liquid caused by the melted water during the use of the ice cubes.

[0045] In the above ice-making process, when the water forms ice cubes in the ice-making bucket 1, the ice-making bucket 1 drives the water to rotate together, and due to the action of the centrifugal force of rotation, a secondary flow pattern will be formed at the bottom of the water at this time. Among them, the secondary flow refers to the deviation of the liquid parallel to the boundary, which is a water flow superimposed on the main flow. Another flow of a different nature caused by one flow (main flow). For example, the flow in the cross-section perpendicular to the axis of the main flow in pipe flow is the secondary flow. Please refer to Figure 17, and the formation of the secondary flow in the device is due to the fact that when water flows at the bottom of the rotating ice-making bucket 1, the water layer near the bottom has a smaller flow velocity, and the centrifugal force is smaller than that at the center of the ice-making bucket 1. As a result, the flow direction at the bottom is inward. This phenomenon can generate a circular water flow that is superimposed on the main flow and coaxial with the ice-making bucket 1. In the figure, the small-diameter arrow circle represents the flow direction of the secondary flow, and the large-diameter arrow circle represents the flow direction of the main flow. The secondary flow increases the flow area between the water and the surface of the ice-making bucket 1, thereby increasing the heat transfer efficiency, that is, increasing the heat exchange between the water and the surface of the ice-making bucket 1. And through the rotation phenomenon of the secondary flow and the main flow of water, multiple stirrings in different directions are generated. This kind of stirring will quickly bring the bubbles in the water to the liquid surface and release them. Once the bubbles reach the liquid surface, they will break away from the liquid and be released. Through this multi-directional stirring, most of the bubbles in the water are effectively removed. In this way, the gas content in the ice cubes produced by the ice-making bucket 1 will be reduced, and the transparency of the ice cubes will also be improved, making the ice cubes look clearer and more transparent. At the same time, it will also speed up the condensation speed of the ice cubes and improve the ice output efficiency. The improvement of the ice-making rate enables the device to produce ice and discharge ice at the same time.
