Description

Technical Field

[0001] This invention relates to the field of ice-making equipment technology, and in particular to an ice-making device, an ice-making system, and an ice-making method thereof. Background Technology

[0002] As people's living standards continue to improve, the ice-making function in household or commercial refrigeration equipment such as refrigerators and freestanding ice makers has become an important feature. Currently, ice-making equipment on the market typically only produces ice cubes of specific shapes, such as the common crescent-shaped ice, cube-shaped ice, or bullet-shaped ice. However, different usage scenarios have different requirements regarding the shape and melting speed of the ice.

[0003] For example, cube ice, due to its larger specific surface area, can fully contact beverages for rapid cooling, making it widely applicable to everyday cold drinks, sodas, and similar beverages. Spherical ice, on the other hand, has the smallest specific surface area for its volume, resulting in the slowest melting rate and minimizing dilution of beverages, thus preserving their original flavor. To meet users' needs for different types of ice, they typically need to purchase different types of ice-making equipment, increasing both their economic costs and space requirements.

[0004] Therefore, related technologies integrate two or more completely independent ice-making systems within a single ice-making device. For example, separate refrigeration circulation pipelines and evaporators are set up for making cube ice and spherical ice. While this enables multiple ice-making functions, the entire ice-making system has an exceptionally complex structure, numerous components, and difficult control logic. This significantly increases the manufacturing cost and failure risk of the ice-making equipment, and also reduces the usable space inside the equipment. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in related technologies. To this end, this invention provides an ice-making device, an ice-making system, and an ice-making method. By connecting two evaporator components with different functions in parallel, a single refrigeration cycle system can be used to prepare two or more types of ice on demand or simultaneously, simplifying the system structure, reducing the manufacturing cost of the ice-making device, and saving structural space of the ice-making device.

[0006] A first aspect of the present invention provides an ice-making system comprising: A refrigeration cycle loop, comprising a compressor and a condenser connected in sequence; A valve assembly having an inlet, a first outlet, and a second outlet, wherein the inlet of the valve assembly is connected to the outlet of the condenser; A first refrigeration branch is connected between the first outlet of the valve assembly and the inlet of the compressor, and a first throttling element and a first evaporator assembly are sequentially arranged in the first refrigeration branch; The second refrigeration branch is connected between the second outlet of the valve assembly and the inlet of the compressor. The second refrigeration branch is provided with a second throttling element and a spray evaporator in sequence. The valve assembly selectively introduces refrigerant from the condenser into at least one of the first refrigeration branch and the second refrigeration branch.

[0007] The ice-making system provided in this embodiment of the invention connects two evaporator components with different functions in parallel, and uses a single refrigeration cycle system to realize the on-demand or simultaneous preparation of two or more types of ice. This simplifies the system structure, reduces the manufacturing cost of the ice-making equipment, saves the structural space of the ice-making equipment, and makes it easier to integrate into products such as refrigerators, wine cabinets, or independent ice-making equipment.

[0008] Furthermore, this parallel configuration of the first evaporator assembly and the spray evaporator, through the valve assembly, provides the ice-making system with high flexibility, allowing selection of the refrigerant flow direction to achieve independent control of the operating status of the two evaporator assemblies. This not only enables switching between single-ice-making mode and simultaneous ice-making mode, but more importantly, it provides the hardware foundation for independently adjusting the cooling capacity and evaporation temperature of the two evaporators, which is difficult to achieve with a series structure.

[0009] A second aspect of the present invention provides an ice-making method using the ice-making system described in any one of the above claims, comprising at least one of the following ice-making modes: The valve assembly is controlled to introduce refrigerant into the first refrigeration branch to make ice in the first evaporator assembly; The valve assembly is controlled to introduce refrigerant into the second refrigeration branch to make ice in the spray evaporator; The valve assembly is controlled to simultaneously introduce refrigerant into the first refrigeration branch and the second refrigeration branch to simultaneously produce ice in the first evaporator assembly and the spray evaporator.

[0010] A third aspect of the present invention provides an ice-making apparatus, comprising: A water box assembly includes a water box body and an inner shell. The inner shell is located inside the water box body and forms a water inlet cavity with the water box body. The inner shell is provided with multiple turbulence holes. And any of the above-mentioned ice-making systems, wherein the first evaporator assembly in the ice-making system and the inner shell form a first ice-making cavity, and the first ice-making cavity is connected to the water inlet cavity through the turbulence hole.

[0038] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0039] See Figure 1 This invention provides an ice-making system, which includes a refrigeration cycle loop 100 and a valve assembly 130, as well as a first refrigeration branch 140 and a second refrigeration branch 150 branched from the valve assembly 130. The refrigeration cycle loop 100 includes a compressor 110 and a condenser 120 connected in sequence.

[0040] Specifically, valve assembly 130 has an inlet, a first outlet, and a second outlet, with the inlet of valve assembly 130 connected to the outlet of condenser 120. A first refrigeration branch 140 connects the first outlet of valve assembly 130 and the inlet of compressor 110, and a first throttling element 141 and a first evaporator assembly 10 are sequentially arranged in the first refrigeration branch 140. A second refrigeration branch 150 connects the second outlet of valve assembly 130 and the inlet of compressor 110, and a second throttling element 151 and a spray evaporator 420 are sequentially arranged in the second refrigeration branch 150.

[0041] Unlike the series structure, the first refrigeration branch 140 and the second refrigeration branch 150 are parallel, and each refrigeration branch constitutes a relatively independent refrigeration unit, each containing an independent throttling device and evaporator assembly. The outlets of the two refrigeration branches eventually merge, sending the evaporated refrigerant gas back to the inlet of the compressor 110.

[0042] The valve assembly 130 selectively directs refrigerant from the condenser 120 into at least one of the first refrigeration branch 140 and the second refrigeration branch 150. That is, the inlet of the valve assembly 130 receives high-pressure liquid refrigerant from the condenser 120 and, according to control commands, selectively distributes it to one or more outlets.

[0043] It is understood that the ice-making system provided in this embodiment of the invention, by connecting two evaporator components with different functions in parallel, can realize the on-demand or simultaneous preparation of two or more types of ice using a single refrigeration cycle system, which simplifies the system structure, reduces the manufacturing cost of ice-making equipment, saves structural space of ice-making equipment, and is easier to integrate into products such as refrigerators, wine cabinets or independent ice-making equipment.

[0044] Furthermore, this parallel arrangement of the first evaporator assembly 10 and the spray evaporator 420, through the valve assembly 130, provides the ice-making system with high flexibility, allowing selection of the refrigerant flow direction to achieve independent control of the operating status of the two evaporator assemblies. This not only enables switching between single-ice-making mode and simultaneous ice-making mode, but more importantly, it provides the hardware foundation for independently adjusting the cooling capacity and evaporation temperature of the two evaporators, which is difficult to achieve with a series structure.

[0045] In some embodiments of the present invention, the ice-making system further includes a bypass pipe 160 and a solenoid valve 170. One end of the bypass pipe 160 is connected between the outlet of the compressor 110 and the inlet of the condenser 120, and the other end of the bypass pipe 160 is connected to the inlet of the first evaporator assembly 10 and the inlet of the spray evaporator 420, respectively. The solenoid valve 170 is disposed on the bypass pipe 160. Essentially, by adding the bypass pipe 160 and the solenoid valve 170 to the ice-making system, the high-temperature, high-pressure gaseous refrigerant discharged from the compressor 110 can be directly led to the inlet of the first evaporator assembly 10 and the inlet of the spray evaporator 420 before entering the condenser 120 for heat dissipation, thus achieving de-icing.

[0046] The controller is also configured to open the solenoid valve 170 when de-icing is required, so that the high-temperature gaseous refrigerant from the compressor 110 is directly sent to the first evaporator assembly 10 and the spray evaporator 420 via the bypass line 160.

[0047] In a normal ice-making cycle, the low-temperature refrigerant flows through the refrigerant channel along the normal path for cooling. Once the ice is completely frozen, the control system initiates the de-icing procedure. At this time, the solenoid valve 170 actuates, cutting off the low-temperature refrigerant from the throttling device and instead introducing high-temperature, high-pressure gaseous refrigerant from the compressor 110 outlet directly into the refrigerant channels of the first evaporator assembly 10 and the spray evaporator 420. This high-temperature refrigerant rapidly heats the entire evaporator assembly, causing the thin layer of ice in contact with the evaporator assembly to melt first, forming a water film. Under gravity, the formed ice blocks separate smoothly from the ice tray and fall into the ice storage box below. After de-icing is complete, the reversing mechanism actuates again, restoring the normal refrigeration cycle.

[0048] In some embodiments of the present invention, the ice-making system further includes a dryer filter disposed between the condenser 120 and the valve assembly 130. By explicitly disposing the dryer filter between the condenser 120 and the valve assembly 130, its function is to absorb trace amounts of moisture in the refrigerant and filter impurities, thereby preventing ice blockage inside the valve assembly 130 and the throttling device, and ensuring long-term stable operation of the ice-making system.

[0049] In some embodiments of the present invention, the first throttling element 141 and the second throttling element 151 are both capillary tubes, electronic expansion valves, or thermostatic expansion valves. The function of the throttling element is to reduce the pressure and temperature of the high-pressure liquid refrigerant. Unlike the passively throttling capillary tube, the electronic expansion valve or thermostatic expansion valve is an active flow control element that can dynamically adjust the refrigerant flow rate according to the outlet temperature of the evaporator assembly or the instructions of the controller.

[0050] For example, in the initial stage of ice making, the evaporation temperature can be increased to quickly cool the water to its freezing point using a larger cooling capacity; during the freezing stage, the evaporation temperature can be lowered to accelerate the freezing rate by utilizing a large heat exchange temperature difference. Optimizing control in stages can improve ice-making efficiency, shorten ice-making time, and reduce energy consumption.

[0051] In some embodiments of the present invention, when both the first throttling element 141 and the second throttling element 151 are capillary tubes: the lengths of the first throttling element 141 and the second throttling element 151 are different, or the inner diameters of the first throttling element 141 and the second throttling element 151 are different, so that when ice is made simultaneously, the operating evaporation temperatures of the first evaporator assembly 10 and the spray evaporator 420 are different.

[0052] Essentially, the two parallel refrigeration branches have differentiated throttling characteristics, meaning they use two capillary tubes with different parameters. For example, different throttling effects can be easily achieved by using capillary tubes of different lengths or inner diameters. Under the same inlet pressure, the different throttling effects result in different evaporation pressures and temperatures for the refrigerant entering the evaporator.

[0053] Generally, the optimal freezing process parameters may differ depending on the type of ice. For example, preparing large, transparent spherical ice cubes may require a relatively gentle freezing process, while rapidly preparing small cubes of ice requires a stronger cooling intensity. By matching different throttling devices to the two cooling branches, personalized optimization can be performed for different ice types. When making ice simultaneously, both types of ice can be generated under their respective optimal operating conditions, thereby optimizing the overall ice-making speed and ice quality.

[0054] In some embodiments of the invention, the ice-making system further includes a heating element disposed on at least one of the first evaporator assembly 10 and the spray evaporator 420. Specifically, the electric heating element may be directly disposed on the evaporator assembly.

[0055] This invention also provides an ice-making method using the ice-making system of any of the above embodiments, including at least one of the following ice-making modes: First ice-making mode: The controller commands the valve assembly 130 to direct all refrigerant into the first refrigeration branch 140. At this time, no refrigerant flows through the second refrigeration branch 150, and it is completely inactive. 100% of the cooling capacity is concentrated in the first evaporator assembly 10, achieving efficient single-circuit ice making.

[0056] Second ice-making mode: Similarly, the controller can introduce all the refrigerant into the second refrigeration branch 150, so that the first evaporator assembly 10 stops working and ice is made only in the spray evaporator 420.

[0057] Simultaneous ice-making mode: The controller commands the valve assembly 130 to distribute the refrigerant to the two branches at a certain ratio, thereby enabling the two evaporator assemblies to make ice simultaneously.

[0058] In some embodiments of the present invention, the ice-making method further includes any one of the following de-icing methods: Hot gas de-icing: By setting a bypass line 160 and a solenoid valve 170, when de-icing is required, the compressor 110 is run and the valve assembly 130 is controlled to open the bypass line 160 connected between the outlet of the compressor 110 and the inlet of the evaporator, so that the high-temperature refrigerant gas discharged from the compressor 110 is directly introduced into one or two evaporators, and de-icing is carried out by utilizing the waste heat of the ice-making system itself.

[0059] Electrothermal de-icing: During de-icing, heat is generated by energizing the heating element to melt the contact surface between the ice and the evaporator assembly.

[0060] It should be noted that the first evaporator assembly 10 can be a square ice or bullet ice evaporator to meet the demand for large-volume, rapid ice use. The spray evaporator 420 can be a spherical ice evaporator to meet high-end needs, or a cold plate evaporator equipped with replaceable ice molds. Ice molds of different shapes, such as heart-shaped and star-shaped, are installed on the cold plate to achieve customization of any ice shape.

[0061] It should also be noted that compressor 110 is a variable frequency compressor 110. Because the cooling load of the ice-making system is dynamic—for example, the load is low when a single evaporator is working, and high when both evaporators are working simultaneously—the variable frequency compressor 110 can automatically adjust its operating frequency and output power according to the actual cooling load. Compared to the fixed frequency compressor 110, which can only be fully on or fully off, the variable frequency compressor 110 can operate at low speed under low load and at high speed under high load, thus achieving more precise temperature control, lower energy consumption, and lower operating noise.

[0062] See Figures 2 to 24 The present invention also provides an ice-making device, which includes a water box assembly and an ice-making system provided in any of the above embodiments.

[0063] The water box assembly 20 is rectangular and has an inlet chamber 211 inside. The first evaporator assembly 10 and the water box assembly 20 form a first ice-making chamber 221, which is connected to the inlet chamber 211 through a turbulence hole 222. The disturbance component 30 includes a drive mechanism 310, a disturbance mechanism 320, a first magnetic attraction mechanism 330, and a second magnetic attraction mechanism 340. The drive mechanism 310 and the first magnetic attraction mechanism 330 are both located outside the water box assembly 20 and are connected to the first magnetic attraction mechanism 330. The disturbance mechanism 320 and the second magnetic attraction mechanism 340 are both located inside the inlet chamber 211 and are connected to the second magnetic attraction mechanism 340. The first magnetic attraction mechanism 330 and the second magnetic attraction mechanism 340 are magnetically attracted to each other. The drive mechanism 310 is adapted to drive the disturbance mechanism 320 to rotate, and the disturbance mechanism 320 is adapted to drive the water in the inlet chamber 211 to flow.

[0064] The ice-making equipment provided by this invention, such as Figure 14 As shown, the connection between the drive mechanism 310 and the disturbance mechanism 320 is achieved through the magnetic attraction of the first magnetic attraction mechanism 330 and the second magnetic attraction mechanism 340. This allows the drive mechanism 310 to drive the disturbance mechanism 320 to rotate through the first magnetic attraction mechanism 330 and the second magnetic attraction mechanism 340. There is no need to open a hole in the water box assembly 20 to connect the drive mechanism 310 and the disturbance mechanism 320, thus avoiding water leakage and simplifying the structure of the ice-making equipment.

[0065] By placing the first magnetic attraction mechanism 330 outside the water tank assembly 20 and connecting it to the drive mechanism 310, and placing the second magnetic attraction mechanism 340 inside the water tank assembly 20 and connecting it to the disturbance mechanism 320, power transmission is achieved through the magnetic attraction between the first magnetic attraction mechanism 330 and the second magnetic attraction mechanism 340. This ultimately achieves a non-contact connection between the drive mechanism 310 and the disturbance mechanism 320, allowing the rotating magnetic field generated by the external drive mechanism 310 to penetrate the side wall of the water tank assembly 20 when it rotates. This magnetic force stably drives the disturbance mechanism 320 inside the water tank to rotate synchronously. In this way, the entire power transmission process does not require any through holes in the water tank assembly 20 for installing the drive shaft, avoiding the need for seals in mechanical transmission methods where the drive shaft passes through the water tank assembly 20. This prevents leakage problems that may occur due to aging, wear, or improper installation of seals, improving the product's safety and durability. Furthermore, by eliminating the complex sealing structure, the overall structure of the ice-making equipment is simplified, reducing the number of parts and production costs, making the assembly process more convenient and efficient.

[0066] It is understandable that, such as Figure 5 and Figure 7 As shown, the water box assembly 20 includes a water box body 210 and an inner shell 220. The first evaporator assembly 10 and the inner shell 220 form a first ice-making chamber 221. The water box body 210 is located on the side of the inner shell 220 away from the first evaporator assembly 10. The water box body 210 and the inner shell 220 form a water inlet chamber 211. A turbulence hole 222 is provided on the inner shell 220. The turbulence hole 222 serves as a channel connecting the water inlet chamber 211 and the first ice-making chamber 221. It not only ensures a continuous supply of water required for ice making, but more importantly, it guides the water flow to circulate between the two chambers in a preset manner. In conjunction with the operation of the turbulence mechanism 320, it effectively removes the air dissolved in the water, generating crystal clear, bubble-free, high-quality ice cubes.

[0067] Understandable, Figure 15As shown, the agitation mechanism 320 includes a connecting rod 321 and a baffle plate 322. The connecting rod 321 is disposed in the water inlet chamber 211 and is horizontally arranged along the width direction of the water box assembly 20. The connecting rod 321 is connected to the water box body 210 and is adapted to provide an installation base for the second magnetic attraction mechanism 340. The second magnetic attraction mechanism 340 is rotatably sleeved on the first end of the connecting rod 321. The baffle plate 322 is adapted to drive the water in the water inlet chamber 211 to flow. The baffle plate 322 is fixedly connected to the second magnetic attraction mechanism 340, so that the rotational torque transmitted from the external driving force can be directly and without loss transmitted to the baffle plate 322, thereby efficiently agitating the water in the water inlet chamber 211, forming a continuous flow, accelerating the discharge of dissolved air in the water, and making the water temperature in the water inlet chamber 211 uniform, which helps to produce high-quality ice cubes with fewer bubbles and greater purity and transparency.

[0068] It is understandable that, such as Figure 17 As shown, the connecting rod 321 includes a connecting rod body 323 and a plug-in rod 324. A retainer is provided on the side wall of the water inlet cavity 211 away from the first magnetic attraction mechanism 330, and a slot is provided on the upper part of the retainer. By providing a retainer on the side wall of the water inlet cavity 211 away from the first magnetic attraction mechanism 330 and providing a slot on its upper part, the first end of the connecting rod body 323 can be directly engaged in the retainer through the slot, realizing quick installation and positioning without tools, simplifying the assembly steps, improving production efficiency, and also providing convenience for possible subsequent maintenance or cleaning. The second end of the connecting rod body 323 is provided with a plug-in hole, and the first end of the plug-in rod 324 is inserted into the plug-in hole. The cross-section of the plug-in rod 324 is a non-circular cross-section, which ensures that the plug-in rod 324 and the connecting rod body 323 are coaxially arranged and there is no relative rotation between them. This arrangement not only reduces the injection molding difficulty of a single slender part, but more importantly, it makes it possible to complete the installation of the transverse support rod in a closed cavity, ensuring that the assembled rod has good overall rigidity and torque transmission capability.

[0069] On the other side of the water inlet chamber 211, near the side wall of the first magnetic attraction mechanism 330, a blind hole is correspondingly provided. The second end of the plug rod 324 is inserted into this blind hole, thereby fixing both ends of the connecting rod 321. The blind hole provides a stable support point for the connecting rod 321 while maintaining the closed integrity of the water box wall. Preferably, the inner diameter of the blind hole gradually increases in the direction away from the first magnetic attraction mechanism 330, thus forming a tapered guide opening. This plays a guiding role during assembly, allowing the end of the plug rod 324 to be easily and accurately aligned and inserted into the blind hole, reducing assembly difficulty, avoiding component damage caused by misalignment or jamming, and further improving the convenience and reliability of installation.

[0070] It is understandable that, such as Figure 17As shown, the connecting rod 321 also includes a rotating sleeve 325, which is rotatably fitted onto the insertion rod 324. The second magnetic attraction mechanism 340 is fitted onto the outer circumferential surface of the rotating sleeve 325. The rotating sleeve 325 is rotatably fitted onto the insertion rod 324, which serves as a fixed shaft, thus forming a dedicated sliding bearing structure between the fixed insertion rod 324 and the rotating component. By concentrating the rotational friction entirely between the inner surface of the rotating sleeve 325 and the outer surface of the insertion rod 324, a self-lubricating material with a lower coefficient of friction can be used to manufacture the rotating sleeve 325, thereby reducing rotational resistance. This makes the start-up and operation of the entire disturbance mechanism 320 more stable and smooth, and significantly improves the durability and service life of the rotating component. The second magnetic attraction mechanism 340 is fitted onto and fixedly connected to the outer circumferential surface of the rotating sleeve 325, so that the second magnetic attraction mechanism 340 itself no longer needs to directly rotate relative to the fixed insertion rod 324, extending the service life of the second magnetic attraction mechanism 340.

[0071] It is understandable that, such as Figure 17 As shown, a limiting ring 326 is integrally formed or fixedly provided on the outer circumferential surface of the plug rod 324, providing a rigid limiting mechanism for the axial movement of the rotating sleeve 325, so that the first side of the rotating sleeve 325 forms a limiting engagement with the end face of the limiting ring 326. Based on this, by simultaneously forming a limiting engagement with the end face of the second end of the connecting rod body 323 on the other side of the rotating sleeve 325, the rotating sleeve 325 is precisely "clamped" and constrained within a predetermined working area between the two. This bidirectional limiting structure effectively prevents any unnecessary axial movement or drift of the rotating sleeve 325 during rotation, ensuring that the second magnetic attraction mechanism 340 fixed thereon always maintains the optimal magnetic coupling distance and alignment position with the external first magnetic attraction mechanism 330, thereby ensuring the high efficiency and stability of power transmission. It also avoids collisions and friction between the rotating component and the inner wall of the water cavity or other components due to axial movement, ensuring the smooth operation of the equipment.

[0072] It is understandable that, such as Figure 17As shown, the second magnetic attraction mechanism 340 includes a mounting base 341 and a first magnet 342. The mounting base 341 has a central hole, allowing it to be directly fitted onto and fixed to the outer circumference of the rotating sleeve 325. A baffle plate 322 is positioned on the side of the mounting base 341 away from the first magnetic attraction mechanism 330. This arrangement effectively separates the magnetic coupling area responsible for power transmission from the fluid action area responsible for agitating the water flow, providing physical isolation to the sidewall of the water box body 210. This ensures that the first magnet 342 and the second magnet 331 are as close as possible to each other to achieve maximum magnetic torque, while avoiding interference with the magnetic field during rotation of the baffle plate 322. This optimizes both power transmission and fluid agitation functions. The first magnet 342 is mounted on the mounting base 341, which provides a mounting foundation for the first magnet 342, ensuring that all first magnets 342 are evenly and firmly distributed around the circumference.

[0073] Understandably, by providing four circumferentially spaced first grooves on the side of the mounting base 341 away from the first magnetic attraction mechanism 330, a mounting base is provided for the four first magnets 342, ensuring that all the first magnets 342 are evenly distributed in the circumferential direction, thereby achieving good dynamic balance performance, reducing vibration and noise during rotation, and making the disturbance mechanism 320 operate more smoothly; at the same time, by embedding the four first magnets 342 one by one into the four grooves, it is ensured that the first magnets 342 will not shift under high-speed rotation and magnetic force, ensuring the stability and reliability of torque transmission.

[0074] A limiting step is provided on the edge of the central hole away from the first magnetic attraction mechanism 330, and the baffle 322 is fitted onto the limiting step. By providing a limiting step on the edge of the central hole of the mounting base 341 away from the first magnetic attraction mechanism 330, a fixed foundation is provided for the installation of the baffle 322, enabling rapid installation of the baffle 322. After installation, the baffle 322 also covers the opening of the first groove. On the one hand, the baffle 322 itself acts as a cover plate, completely encapsulating the first magnet 342 in the dry groove cavity. This encapsulation effectively prevents the magnet from directly contacting water, ensuring the cleanliness and safety of the ice-making water. On the other hand, it also uses the limiting step of the mounting base 341 to fix itself, reducing the number of parts and simplifying the assembly process.

[0075] It is understood that the first magnetic attraction mechanism 330 includes a rotating seat and a second magnet 331. The rotating seat is connected to the connecting shaft of the drive mechanism 310. The second magnet 331 is disposed on the rotating seat and magnetically engages with the first magnet 342.

[0076] It is understandable that, such as Figure 14As shown, the rotating seat includes a rotating seat body 332 and a connecting piece 333. The rotating seat body 332 is disc-shaped, which ensures uniform mass distribution during rotation, facilitating dynamic balance and ensuring smooth rotation, effectively reducing vibration and noise during operation. Four second grooves are provided on the side of the rotating seat body 332 opposite to the second magnetic attraction mechanism 340. These four grooves are equidistantly arranged circumferentially. This equidistant layout ensures uniform distribution of the weight and magnetic force of the subsequently installed second magnets 331, avoiding rotational instability or uneven magnetic force caused by eccentricity. There are four second magnets 331, each correspondingly embedded in one of the four second grooves. The number of second grooves is not limited to this and is determined based on the number of second magnets 331. The connecting piece 333 is disc-shaped and is sleeved on the connecting shaft of the drive mechanism 310, achieving a reliable connection between the rotating seat and the external drive source. The connecting piece 333 is located on the side of the rotating seat body 332 away from the second magnetic attraction mechanism 340 and covers the opening of the second groove.

[0077] Understandably, the number of first magnets 342 is the same as the number of second magnets 331, and the positions of the first magnets 342 and the second magnets 331 correspond one-to-one. This arrangement ensures a stable and balanced magnetic field coupling between the first magnetic attraction mechanism 330 and the second magnetic attraction mechanism 340, thereby maximizing the efficiency of magnetic force transmission and ensuring that power can be transmitted from the drive mechanism to the baffle plate 322 without loss and with high efficiency. The four first magnets 342 are arranged symmetrically in pairs. This symmetrical arrangement gives the first magnetic attraction mechanism 330 excellent dynamic balance performance when rotating, effectively avoiding vibration and noise caused by uneven mass distribution, and ensuring the smoothness and quietness of equipment operation. The magnetic poles of adjacent first magnets 342 are set oppositely. Through the alternating arrangement of N and S poles, a rapidly changing magnetic field gradient is formed between adjacent magnets. This layout can generate a stronger magnetic force during rotation, whether it is an attractive or repulsive force, thus providing a strong driving torque for rotation and ensuring reliable synchronous rotation. The magnetic pole of the end of the first magnet 342 near the second magnet 331 is the same as the magnetic pole of the end of the second magnet 331 near the first magnet 342. When the first magnet 342 on the driving side rotates, the repulsive force it generates will "push" the second magnet 331 on the driven side to rotate synchronously, realizing non-contact torque transmission. This repulsive coupling method transmits power.

[0078] It is understood that one of the connecting piece 333 and the rotating seat body 332 is provided with multiple latches, which are arranged circumferentially at intervals. The other of the connecting piece 333 and the rotating seat body 332 is provided with multiple snap-fit ​​holes, which are also arranged circumferentially at intervals. The multiple latches pass through the multiple snap-fit ​​holes one by one and then snap onto the edge of the snap-fit ​​holes. This connection method, which uses elastic latches and snap-fit ​​holes to cooperate, allows the assembly process to be completed simply by aligning and applying pressure, making the operation extremely simple. This enables a quick connection between the connecting piece 333 and the rotating seat body 332, simplifying the assembly method of the connecting piece 333 and the rotating seat body 332. This tool-free and fastener-free assembly mode shortens the assembly time on the production line, reduces the skill requirements for operators, and improves production efficiency, ultimately directly translating into a reduction in manufacturing costs and an increase in product capacity. Of course, the connection method between the connecting piece 333 and the rotating seat body 332 is not limited to this; other detachable connection methods can also be used.

[0079] like Figures 4 to 8 As shown, the ice-making device includes a first evaporator assembly 10 and a water box assembly 20. The water box assembly 20 includes a water box body 210, an inner shell 220, and a pressing mechanism 230. The inner shell 220 and the first evaporator assembly 10 form a first ice-making chamber 221. The water box body 210 is located on the side of the inner shell 220 away from the first evaporator assembly 10, and the water box body 210 and the inner shell 220 form a water inlet chamber 211. The inner shell 220 is provided with a turbulence hole 222 that connects the water inlet chamber 211 and the first ice-making chamber 221. The inner shell 220 is made of a flexible material. The pressing mechanism 230 is located on the water box body 210. The pressing mechanism 230 is adapted to squeeze the inner shell 220 to deform during de-icing, so that the ice block is separated from the inner shell 220.

[0080] According to the ice-making equipment provided by the present invention, since the inner shell 220 is made of a flexible material, it can easily undergo recoverable deformation under external force. During the ice removal process, by pressing the pressing mechanism 230 by hand, the pressing mechanism 230 further compresses the flexible inner shell 220 under pressure, causing it to deform locally or entirely. This method of separating ice blocks through compression and deformation simplifies the overall mechanical structure, reducing manufacturing costs and achieving higher reliability and longer service life due to the reduction of moving parts. Throughout the entire ice removal process, the pressing mechanism 230 always acts on the outer wall of the inner shell 220, avoiding direct contact between the pressing mechanism 230 and the ice blocks inside the inner shell 220, thus ensuring the food-grade hygiene of the ice blocks.

[0081] It is understandable that the first ice-making cavity 221 is spherical, and the inner shell 220 is hemispherical, so the ice block produced is spherical ice. Of course, the first ice-making cavity 221 can also be an ellipsoid, an animal shape, or other shapes, and the shape of the inner shell 220 can be adjusted according to the shape of the first ice-making cavity 221.

[0082] It is understandable that, such as Figure 5 and Figure 7 As shown, the first evaporator assembly 10 includes a first evaporator. A first receiving cavity is provided on the side of the first evaporator facing the water box assembly 20, and a second receiving cavity is provided on the side of the inner shell 220 facing the first evaporator assembly 10. Both the first and second receiving cavities are hemispherical. When the inner shell 220 is in contact with the top of the first evaporator, the first and second receiving cavities communicate to form a spherical first ice-making cavity 221. In this embodiment, the first evaporator has two first receiving cavities, which are spaced apart along the length of the first evaporator.

[0083] The first evaporator includes a first shell 11 and a second shell 12, both made of metal. A first receiving cavity is located on the side of the first shell 11 facing away from the second shell 12, forming a protrusion on the side of the first shell 11 facing the second shell 12. A clearance recess is provided on the side of the second shell 12 facing the first shell 11, with the protrusion located within the clearance recess. The edges of the first shell 11 and the second shell 12 are welded together and sealed. A certain distance is spaced between the protrusion and the clearance recess to form a medium flow channel. One end of the second shell 12 is provided with a medium inlet 14, and the other end is provided with a medium outlet 15, both of which are connected to the medium flow channel. When the ice-making equipment is working, the cooling medium flows into the medium flow channel through the medium inlet 14 and fills the medium flow channel. The cooling medium exchanges heat with the water in the first ice-making chamber 221 in the medium flow channel, causing the water to freeze into ice. After heat exchange, the medium flows out of the medium flow channel through the medium outlet 15.

[0084] Furthermore, the first evaporator also includes a brazing filler plate 13, which has a hollow structure and is fitted around the outer periphery of the protrusion. The edge of the first shell 11 is welded to the edge of the second shell 12 through the brazing filler plate 13.

[0085] It is understandable that, such as Figure 5 and Figure 7 As shown, the water tank body 210 is provided with a mounting hole located on the top of the water tank body 210, so as to facilitate direct operation after opening the cover 41 of the ice maker. Of course, the location of the mounting hole is not limited to this and can also be provided in other locations on the water tank body 210.

[0086] The pressing mechanism 230 includes a pressing member 231 and an elastic member 232. The pressing member 231 is vertically arranged, and its first end is movably inserted through a mounting hole. The pressing member 231 is located above the inner housing 220. The number of pressing members 231 and the number of inner housings 220 are the same, and each pressing member 231 corresponds to one inner housing 220. The elastic member 232 is connected to the pressing member 231. The elastic member 232 can store energy and release it after the external force is removed, so that the pressing member 231 automatically returns to its initial position after pressing the inner housing 220. This achieves automatic reset after pressing, eliminating the need for manual reset by the user and improving the convenience of operation and the efficiency of continuous use. The elastic member 232 is suitable for switching between an initial state and a deformed state. In the initial state, the first end of the pressing member 231 is separated from the inner housing 220. In the deformed state, by applying external force to the pressing member 231, its first end abuts against the inner shell 220 and squeezes the flexible inner shell 220 to deform it. The deformation of the flexible inner shell 220 is used to break the adhesion between the ice and the shell surface, thereby allowing the ice to separate from the inner shell 220, achieving an easy and convenient ice removal effect. This method is not only simple and labor-saving to operate, but also effectively avoids the problems of ice breaking or mold damage caused by traditional knocking and twisting methods.

[0087] It is understandable that, such as Figure 5 and Figure 7 As shown, the elastic element 232 includes a compression spring, which is sleeved on the outer periphery of the pressing element 231. The coaxial arrangement of the compression spring and the pressing element 231 makes the overall structure compact and occupies little space, while ensuring that the pressing element 231 is subjected to uniform force during movement, thereby achieving stable and smooth reciprocating motion. The first end of the compression spring abuts against the outer side of the water box body 210, and the second end of the pressing element 231 is provided with a pressing part 238. The cross-sectional area of ​​the pressing part 238 is larger than that of the compression spring, and the second end of the compression spring abuts against the pressing part 238. The pressing part 238 not only provides a larger contact area, improving the user's comfort and ease of operation when pressing, but also serves as the limiting and force-bearing end of the spring, ensuring the smooth transmission of pressure and spring force. Of course, the specific type of the elastic element 232 is not limited to this; it can also be a tension spring or other types of springs.

[0088] It is understandable that, such as Figure 5 and Figure 7As shown, a guide sleeve 233 is provided on the outer side of the water box body 210. The guide sleeve 233 provides precise guidance for the reciprocating motion of the pressing part 231, ensuring that the pressing part 231 always moves stably along the predetermined path, thereby avoiding shaking or deflection during the movement. The pressing part 231 is located inside the guide sleeve 233, and the guide sleeve 233 and the pressing part 231 are coaxially arranged. The compression spring is located between the guide sleeve 233 and the pressing part 231, and the spring is housed inside the guide structure, which not only protects the spring from contamination or damage by external impurities, but also makes the overall structure cleaner and more compact. The pressing part 238 slides in conjunction with the guide sleeve 233. Through the sliding contact between the upper end of the pressing part 238 and the inner wall of the guide sleeve 233, the smoothness of the entire pressing stroke is ensured, improving the operating feel and the reliability of the mechanism.

[0089] It is understandable that, such as Figure 8 As shown, the ice-making equipment also includes a handle 234 and at least two guide sleeves 233. The handle 234 is connected to two of the guide sleeves 233. The handle 234 facilitates the removal of the water tank assembly 20 from the mounting cavity of the bracket 215. Preferably, two guide sleeves 233 are provided, spaced apart along the length of the water tank body 210 on the top of the water tank body 210. One end of the handle 234 is connected to one guide sleeve 233, and the other end of the handle 234 is connected to the other guide sleeve 233, thus forming a complete handle 234 structure, which allows the user to easily and smoothly remove or place the entire ice-making equipment with one hand. The handle 234 and the guide sleeves 233 are integrally formed, reducing the number of parts, simplifying the production process and reducing manufacturing costs. At the same time, the integrated structure also ensures the strength and durability of the connection, avoiding loosening problems that may occur after long-term use.

[0090] It is understandable that, such as Figure 5 and Figure 7 As shown, the pressing mechanism 230 also includes a sealing ring 235, which is sleeved on the first end of the pressing member 231 and seals with the pressing member 231. In the initial state, the sealing ring 235 abuts against and seals with the edge of the mounting hole near the water inlet chamber 211 to prevent water in the water inlet chamber 211 from flowing out through the gap between the pressing member 231 and the mounting hole. In the deformed state, the sealing ring 235 separates from the edge of the mounting hole near the water inlet chamber 211.

[0091] The pressing mechanism 230 also includes a sealing ring 235, which is sleeved on the first end of the pressing member 231 and seals against it. In the initial state, the elastic force of the elastic member 232 causes the sealing ring 235 to abut against the edge of the mounting hole near the water inlet chamber 211 and form a sealing fit, thereby forming a waterproof barrier to prevent water in the water inlet chamber 211 from flowing out through the gap between the pressing member 231 and the mounting hole after water is injected, thus improving the sealing performance of the water box assembly 20. In the deformed state, when the pressing member 231 is pressed down, the sealing ring 235 moves downward and separates from the edge of the mounting hole. At this time, since the water in the water inlet chamber 211 has been discharged, no water will flow out even though there is a gap between the pressing member 231 and the mounting hole.

[0092] It is understandable that, such as Figure 5 and Figure 7 As shown, a positioning groove 236 is provided on the outer peripheral surface of the first end of the pressing member 231. The positioning groove 236 is annular, and the sealing ring 235 is embedded in the positioning groove 236. By setting the positioning groove 236, the sealing ring 235 is effectively prevented from axially moving or falling off during the frequent reciprocating motion of the pressing member 231, thereby improving the stability and reliability of the sealing structure and ensuring the long-lasting effectiveness of the sealing effect.

[0093] Understandably, a sealing bevel is provided on the edge of the mounting hole near the water inlet chamber 211. This bevel extends circumferentially along the mounting hole, forming a complete conical sealing surface, ensuring the continuity and integrity of the seal and preventing any leakage points. In the initial state, under the pre-tightening force of the elastic element 232, the sealing ring 235 tightly abuts against the sealing bevel, forming a sealing fit. This bevel contact method decomposes the axial spring pressure into a larger positive pressure perpendicular to the bevel, thus achieving a good sealing effect with only a small amount of elastic force. Simultaneously, by setting the sealing bevel, the contact area between the water box body 210 and the sealing ring 235 is increased, further improving the sealing reliability of the water box assembly 20.

[0094] It is understandable that, such as Figure 5 and Figure 7As shown, the first end of the pressing member 231 is provided with a contact portion 237, the cross-sectional area of ​​which is larger than the cross-sectional area of ​​the rod portion of the pressing member 231. This design aims to increase the contact area between the pressing member 231 and the inner shell 220, thereby effectively dispersing the pressure acting on the flexible inner shell 220 when pressure is applied. This avoids the risk of the pressing member 231 tip piercing or damaging the inner shell 220 due to excessive stress concentration, thus improving the durability and reliability of the mechanism. Simultaneously, the larger contact area allows the pressure to be transmitted more evenly to the inner shell 220, causing it to deform more gently and over a wider range. This more efficiently breaks the adhesion between the ice and the shell, making the de-icing operation easier and more thorough.

[0095] Understandably, a positioning sleeve is provided on the side of the inner housing 220 facing the pressing member 231. When the pressing member 231 moves downward, its first end is inserted into the positioning sleeve, providing precise positioning for the pressing member 231. Then, the pressing member 231 continues to move downward, deforming the inner housing 220 connected to the positioning sleeve by pressing it. Because the pressing position is precisely positioned, it ensures that each press acts on the most effective deformation area of ​​the inner housing 220, thereby achieving efficient and reliable de-icing. The positioning sleeve can position the lower end of the pressing member 231, fundamentally preventing the lower end of the pressing member 231 from shifting due to uneven force or gap tolerance. This avoids local damage to the inner housing 220 or de-icing failure due to misaligned pressing, greatly improving the product's durability and the success rate of user operation.

[0096] Understandably, there are multiple turbulence holes 222. By setting multiple turbulence holes 222 as connecting channels, the redundancy and efficiency of water flow are ensured. Even if some turbulence holes 222 are slightly blocked due to freezing, the remaining turbulence holes 222 can still maintain normal water exchange, ensuring the stability of the ice-making process. Multiple turbulence holes 222 are evenly distributed in the inner shell 220, ensuring that water can flow in every part of the first ice-making chamber 221. This establishes a uniform temperature field and flow field in the first ice-making chamber 221, allowing the water in the water in the water inlet chamber 211 and the water in the first ice-making chamber 221 to flow and circulate fully. During the slow process of water freezing into ice, the gas and impurities in the water are carried away by the continuously flowing liquid water and are not trapped in the ice crystals. Ultimately, this ensures that the ice block produced is bubble-free and crystal clear, improving the quality of the ice block.

[0097] It is understandable that, such as Figures 8 to 13As shown, at least two inlet / outlet ports 212 communicating with the inlet chamber 211 are provided on the side wall of the water box body 210, and the at least two inlet / outlet ports 212 are spaced apart in the vertical direction. By providing at least two inlet / outlet ports 212 communicating with the inlet chamber 211 on the side wall of the water box body 210, multiple water flow channels are provided. Compared with the design of a single inlet / outlet port 212, the redundancy and reliability of the pipeline are improved, avoiding the risk of the entire de-icing process failing due to blockage of a single pipeline. By arranging at least two inlet / outlet ports 212 spaced apart in the vertical direction, even if the lower inlet / outlet port 212 is blocked by ice, the higher inlet / outlet port 212 remains unobstructed and can serve as a backup channel, ensuring that the remaining cold water in the inlet chamber 211 can be discharged smoothly, providing conditions for subsequent injection of de-icing water. Subsequently, high-temperature melting water can be efficiently injected into the inlet chamber 211 through the unobstructed upper inlet / outlet 212, which quickly and evenly heats and melts the ice in the chamber. This effectively solves the problem that traditional single-outlet designs are prone to being blocked by ice during de-icing, ensuring the success rate of de-icing operations and the continuity and stability of the entire ice-making equipment, thus guaranteeing the normal progress of de-icing operations.

[0098] It is understandable that, such as Figure 8 As shown, an overflow port 213 is also provided on the side wall of the water box body 210. When water is injected into the water inlet chamber 211, the overflow port 213 provides a smooth discharge channel for the air in the water inlet chamber 211, effectively avoiding the problem of poor water injection or insufficient water injection caused by back pressure generated by the formation of a closed air chamber in the water inlet chamber 211. The overflow port 213 is located on one side of the upper water inlet and outlet 212. The overflow port 213 is suitable for discharging air and / or excess water in the water inlet chamber 211. By limiting the highest liquid level in the water inlet chamber 211 through its specific height position, it can automatically discharge water exceeding the standard water volume, thereby achieving precise control of the amount of water for each ice making.

[0099] It is understandable that, such as Figure 12As shown, the water box assembly 20 also includes a baffle 214, which is vertically disposed on the inner side wall of the water box body 210. The baffle 214 covers the overflow port 213, and a flow channel communicating with the overflow port 213 is formed between the baffle 214 and the side wall of the water box body 210. This flow channel provides a dedicated and stable channel for air and excess water that is relatively isolated from the main water chamber, ensuring smooth air venting and drainage. Both the upper and lower ends of the baffle 214 are provided with connection ports communicating with the flow channel. Specifically, the height of the upper port of the baffle 214 is greater than the height of the overflow port 213, ensuring that the upper port mainly serves as a high-level venting channel. During water injection, it can efficiently expel the compressed air in the cavity, avoiding air resistance that could affect the water injection speed and accuracy. At the same time, the height of the lower port of the baffle 214 is less than the height of the overflow port 213. During de-icing, even if the lower port of the baffle 214 is temporarily blocked by ice or ice-water mixture due to its proximity to the bottom of the water body, the upper port, which is much higher than the ice-sealed area, remains unobstructed and can serve as a reliable pressure relief and venting channel. This provides an outlet for the air displaced or water vapor generated during subsequent injection of de-icing water, thus completely solving the potential failure point of poor venting and inability to inject de-icing water smoothly due to a blocked single channel. Venting can also be carried out through the upper port, improving the de-icing success rate and operational reliability of the equipment under complex working conditions.

[0100] It is understandable that there are two inlet and outlet ports 212, and the two inlet and outlet ports 212 are on the same vertical line. The height of the overflow port 213 is less than or equal to the height of the upper inlet and outlet port 212.

[0101] Understandably, the baffle 214 is provided with multiple flow holes, which are directly connected to the flow channel, thereby increasing the total flow area for air discharge and effectively improving the efficiency and speed of air discharge. Furthermore, the multiple flow holes are arranged at intervals in the vertical direction, so that no matter the water level in the flow channel, at least one flow hole is always above the water surface, which can smoothly discharge the air accumulated in the upper layer. This avoids the problem that some air is trapped in the flow channel due to water level changes and cannot be discharged, thus ensuring the stability of the exhaust effect.

[0102] It is understandable that, such as Figure 9As shown, the ice-making equipment also includes a bracket 215, which has an internal mounting cavity that provides an integrated mounting space for the first evaporator assembly 10 and the water box assembly 20, making the entire device more compact and providing effective support and protection for the internal components. The top of the bracket 215 has an opening that communicates with the mounting cavity, allowing installers to easily insert or remove core components such as the first evaporator assembly 10 and the water box assembly 20 from above, simplifying assembly and subsequent maintenance processes and improving production and maintenance efficiency. The first evaporator assembly 10 and the water box assembly 20 are stacked sequentially in the mounting cavity from bottom to top.

[0103] It is understandable that, such as Figure 9 and Figure 13 As shown, the ice-making equipment also includes a water-gas connection seat 240. A positioning groove is provided on the side wall of the bracket 215, and the water-gas connection seat 240 is embedded in the positioning groove. The positioning groove provides a precise installation position for the water-gas connection seat 240, ensuring that it can be installed quickly and accurately in the predetermined position. The embedded method ensures the stability and reliability of the connection between the two, avoiding loosening or misalignment caused by factors such as equipment vibration. The water-gas connection seat 240 is centrally provided with an overflow connection port 241 and at least two inlet and outlet water connection ports 242. By integrating multiple fluid interfaces into this independent modular component, the structure of the bracket 215 body is simplified, eliminating the need to open multiple water channels, thereby reducing the processing complexity and manufacturing cost of the bracket 215. The water-gas connection seat 240 fits against the side wall of the water box body 210 so that the inlet and outlet water connection ports 242 and the inlet and outlet water ports 212 can be connected one-to-one, and the overflow connection port 241 is connected to the overflow port 213.

[0104] Understandably, the inner diameter of the inlet / outlet connection 242 is larger than the inner diameter of the inlet / outlet 212. By making the inner diameter of the inlet / outlet connection 242 larger than the inner diameter of the inlet / outlet 212, even if there is a certain vertical or horizontal alignment deviation in the water box assembly 20 during installation, as long as the outline of the inlet / outlet 212 falls within the outline of the inlet / outlet connection 242, an effective flow passage can still be formed between the two, thereby ensuring the continuity of the water circuit. This reduces the installation accuracy requirements of the water / air connector 240.

[0105] Understandably, the edge of the inlet / outlet connection 242 is provided with a first annular sealing gasket 243. The first annular sealing gasket 243 uses its own elasticity to fill the tiny gaps between the connection surfaces. The first annular sealing gasket 243 seals with the edge of the inlet / outlet 212, ensuring that water will not leak from the interface during water intake or drainage. Similarly, the edge of the overflow connection 241 is also provided with a second annular sealing gasket 244. The second annular sealing gasket 244 seals with the edge of the overflow port 213, effectively preventing overflowing water or exhaust air from leaking into the equipment from the interface, avoiding the risk of possible electrical short circuits or component corrosion. Preferably, the sidewall of the bracket 215 or the sidewall of the water tank body 210 is inclined. When the water tank body 210 is installed downwards, the water tank body 210 will be subjected to the horizontal component force of the inclined sidewall of the bracket 215, thereby pressing the first annular sealing gasket 243 and the second annular sealing gasket 244 tighter and tighter. This self-locking design uses the weight of the components themselves and the installation action to continuously apply and enhance the sealing pressure, improving the long-term reliability and sealing performance of the connection. Even if the sealing gasket wears material after long-term use, this structure can compensate to a certain extent.

[0106] Understandably, the ice-making equipment also includes inlet and outlet water pipes, which are interconnected with each inlet and outlet water connection 242. The dispersed interfaces are integrated through a main pipeline to form an integrated water distribution pipeline, thereby simplifying the water system layout of the entire device. Ultimately, all inlet and outlet water connections 242 share a single inlet and outlet water pipe, allowing the entire ice-making equipment to complete all water inlet and outlet operations with only one external interface. This not only simplifies the installation of external pipelines and reduces the number of joints and potential leakage risks, but also reduces material costs and installation space requirements.

[0107] like Figures 2 to 3 As shown, the ice-making device also includes a housing 40, which is hollow inside. The ice-making device is located inside the housing 40. The top of the housing 40 has an ice-removing opening, the position of which corresponds to the opening of the bracket 215, to facilitate the removal of the water box assembly 20. The ice-removing opening is provided with a cover 41, which is hinged to the housing 40.

[0108] It is understandable that, such as Figures 18 to 22As shown, the ice-making equipment also includes a support base 410, a spray evaporator 420, a spray element 430, and a partition 440. The spray evaporator 420 is disposed on the upper part of the support base 410. Multiple ice-making chambers 421 are disposed inside the spray evaporator 420, and multiple ice outlet ports 422 corresponding to and communicating with each ice-making chamber 421 are disposed at the bottom of the spray evaporator 420. The spray element 430 is disposed inside the support base 410 and is adapted to spray water into the interior of the ice-making chambers 421 through the ice outlet ports 422. The spray evaporator 420 is adapted to freeze the water in the ice-making chambers 421 into ice. The partition 440 is disposed at at least one ice outlet port 422, and the thermal conductivity of the partition 440 is lower than that of the spray evaporator 420.

[0109] The ice-making equipment provided by this invention uses a partition 440 made of insulating material between adjacent ice outlet ports 422. Since the thermal conductivity of the partition 440 is lower than that of the spray evaporator 420, while the spray evaporator 420 efficiently cools and rapidly freezes the water flowing over its surface into ice, the water in contact with the partition 440 is unable to reach its freezing point due to the obstruction of heat transfer. Thus, it remains liquid and flows downwards due to gravity, eventually flowing into the water circulation system for reuse. The partition 440 establishes a static thermal barrier between adjacent ice-making areas, effectively preventing "ice bridge" adhesion during ice formation and growth, ensuring that each ice block can be formed independently and completely without any subsequent mechanical separation, improving the convenience of ice dispensing and the integrity of the ice blocks. Simultaneously, because this solution uses a top-down spraying method for ice making, water is evenly sprayed onto the inner surface of the low-temperature ice-making chamber 421 through the spray nozzle 430. During this process, the water remains in a continuous flow state. This dynamic freezing process makes it difficult for air and tiny impurities in the water to be "locked" in the ice crystal structure due to the agitation of the water. Instead, they are carried away by the unfrozen water flow, ensuring that the final ice cubes have a dense internal structure and are free of air bubbles, thus obtaining crystal clear, high-quality ice cubes.

[0110] Understandably, the ice-making chamber 421 is rectangular, and the ice outlet 422 is rectangular, resulting in uniformly shaped, angular square ice cubes. The spray evaporator 420 is designed as a compact cuboid, with six independent ice-making chambers 421 integrated within it, and six corresponding ice outlets 422 at the bottom. These six ice outlets 422 are arranged in a two-row, three-column array. This highly integrated matrix layout allows the device to simultaneously produce multiple ice cubes within a very limited physical space, increasing the ice production rate per unit time and overall work efficiency. To further ensure product quality uniformity, the dimensions of each ice outlet 422 are designed to be completely identical. This ensures that each ice cube produced from different chambers has the same specifications, meeting the standardization and quantitative requirements for ice cubes in commercial applications. By independently setting a rectangular frame-shaped partition 440 at each ice outlet 422, the frame structure not only physically isolates the area of ​​each ice outlet 422, but more importantly, it forms an effective heat barrier between adjacent ice blocks that are forming, fundamentally eliminating the phenomenon of "ice bridges" sticking between ice blocks caused by cold diffusion, and ensuring that all ice blocks can fall off smoothly in an independent and complete individual form.

[0111] Understandably, multiple independent baffles 440 are integrated into a single baffle frame using a one-piece molding process. This ensures that the relative positions of each baffle 440 are fixed, allowing for precise alignment with the ice outlet port 422 array at the bottom of the spray evaporator 420 during installation. This eliminates the need for tedious individual adjustments to each baffle 440, improving assembly efficiency. Furthermore, the baffle frame is designed for detachable connection to the spray evaporator 420, simplifying subsequent cleaning and maintenance. Users or maintenance personnel can easily remove the entire baffle frame, providing a thorough cleaning of the frame itself, the surface of the spray evaporator 420 it covers, and the inner wall of the ice outlet port 422. This effectively removes scale or biofilm that may accumulate over long-term use, ensuring the hygiene and safety of ice production.

[0112] Understandably, an ice outlet is provided on one side of the support base 410, providing a unified discharge channel for all produced ice blocks, facilitating efficient docking with the ice storage box or conveyor below. Multiple baffles 442 are located below the baffle frame near the ice outlet. These baffles 442 are spaced apart along the length of the spray evaporator 420, forming a barrier. When the spray nozzles 430 at the bottom spray water upwards, this barrier effectively intercepts and guides water that might otherwise fly directly towards the ice outlet, causing it to fall back onto the upper surface of the spray nozzles 430. This not only avoids water waste but also ensures the dryness and cleanliness of the exterior of the ice-making equipment and the ice outlet channel. Simultaneously, the baffles 442 prevent water from splashing onto the ice outlet and forming ice clings at its edges, ensuring the ice outlet channel remains unobstructed and allowing ice blocks to slide out smoothly without clogging.

[0113] It is understood that the spray component 430 has a confluence channel 431 inside, and is equipped with a water inlet and multiple sets of nozzle mechanisms. The water inlet is suitable for supplying water to the confluence channel 431, and the nozzle mechanisms are suitable for spraying water into the ice-making chamber 421. Both the water inlet and the multiple sets of nozzle mechanisms are connected to the confluence channel 431. This connection method allows the water flow from the water inlet to be collected and stabilized in a centralized chamber, ensuring that the water flow has reached a stable pressure state before being distributed to each nozzle mechanism, thus ensuring that each nozzle mechanism receives a nearly identical water supply. A support is provided at the bottom of the spray component 430 so that the bottom of the spray component 430 is spaced a certain distance from the bottom of the support base 410, thereby forming a drainage channel 433 between the bottom of the spray component 430 and the bottom of the support base 410. This eliminates the need for additional complex drainage pipes, effectively optimizing the internal space layout and reducing manufacturing costs. The bottom of the support base 410 is provided with a drain outlet 434 that communicates with the drainage channel 433. The drain outlet 434 is rectangular.

[0114] During operation, water first enters the manifold 431 through the inlet, and then is distributed to each nozzle mechanism through the manifold 431. The water is then sprayed onto the ice-making chamber 421 above through each nozzle mechanism. The water that has not frozen into ice flows back to the surface of the spray element 430 under the action of gravity, and then gathers and flows into the drain channel 433. Finally, the water flows out through the drain outlet 434 at the bottom of the support base 410, which is connected to the drain channel 433. After flowing out of the drain outlet 434, the water flows back to the cold water tank through the pipeline under the action of gravity for reuse.

[0115] Understandably, the upper surface of the spray element 430 faces the ice outlet and is inclined downwards. This downward inclination of the spray element 430 has two advantages: First, during ice making, unfrozen water droplets flowing down from the ice-making chamber 421 naturally collect along the inclined surface and are guided into the drainage channel 433, effectively preventing water accumulation on the surface of the spray element 430 and improving the efficiency of the entire water circulation system. Second, when ice making is complete and the de-icing stage begins, the ice blocks that fall off the spray evaporator 420 can smoothly slide downwards along the inclined surface and be accurately guided to the single ice outlet, ultimately reliably sliding into the ice storage chamber below. This avoids ice accumulation and blockage inside the machine, ensuring the smooth operation of the continuous ice-making process.

[0116] It is understood that three sets of nozzle mechanisms are provided in this embodiment. Of course, the number of nozzle mechanisms is not limited to this, and is determined according to the number and arrangement of the ice-making chambers 421. The three sets of nozzle mechanisms are arranged at intervals along the length of the spray evaporator 420 on the upper surface of the spray component 430. Each set of nozzle mechanisms includes two nozzles 435. The nozzles 435 in the same set are arranged at intervals along the width of the spray evaporator 420, and the nozzles 435 are set one-to-one with the ice-making chambers 421. This point-to-point spraying method ensures that each ice-making chamber 421 can obtain an independent water supply source, fundamentally ensuring that the amount of water received by all ice blocks during the forming process is equal and stable. This not only improves the efficiency of water resource utilization, but also ensures that the size, weight and shape of the produced ice blocks are highly consistent.

[0117] Understandably, multiple guide channels 436 are provided between adjacent sets of nozzle mechanisms. These guide channels 436 are arranged at intervals along the length of the spray evaporator 420, forming a guiding area on the upper surface of the spray element 430. This effectively guides the return water within the entire length of the spray evaporator 420, preventing local water accumulation. Adjacent guide channels 436 are parallel to each other and extend along the width of the spray evaporator 420, i.e., along the inclined direction of the upper surface of the spray element 430. This allows the return water to flow smoothly and quickly into the guide channels 436 and be discharged, improving drainage efficiency and reducing the residence time of water on the surface of the spray element 430. The upper and lower ends of the longer guide channels 436 are connected to the drainage channel 433, as are the upper and lower ends of the shorter guide channels 436. When the water in the ice-making chamber 421 flows back to the upper surface of the spray element 430, it can be guided by these guide grooves 436 into the drainage channel 433. This effectively prevents the backflow water from crossing or colliding with the water flow normally sprayed from the nozzle 435, ensuring that the water flow path sprayed towards the ice-making chamber 421 is undisturbed and the flow rate is stable. This, in turn, ensures the uniformity and integrity of the ice block formation, ultimately improving ice-making efficiency and ice block quality.

[0118] It is understandable that the spray element 430 is detachably connected to the support base 410 to facilitate the installation and removal of the spray element 430, thereby facilitating the cleaning and maintenance of the spray element 430.

[0119] Understandably, the spray evaporator 420 has a cooling medium flow channel 423 inside. By placing both the cooling medium flow channel 423 and the ice-making chamber 421 inside the spray evaporator 420, the cold energy transfer path is shortened, thereby improving the overall heat exchange efficiency. The cooling medium flow channel 423 is located above the ice-making chamber 421, allowing the cold energy to evenly cover the entire ice-making chamber 421 from top to bottom, forming an ideal counter-current heat exchange with the water sprayed from below, ensuring that the refrigeration energy is used most effectively in the freezing process. The side wall of the spray evaporator 420 is provided with a cooling medium inlet 424 and a cooling medium outlet 425 that communicate with the cooling medium flow channel 423. During ice making, the cooling medium enters the cooling medium flow channel 423 through the cooling medium inlet 424. Within the cooling medium flow channel 423, it undergoes efficient heat exchange with the water in the ice-making chamber 421 via the inner wall of the spray evaporator 420. This rapidly lowers the temperature of the inner surface of the ice-making chamber 421 below the freezing point, causing the water sprayed onto it to quickly freeze into ice blocks within the ice-making chamber 421. This shortens the time required for a single ice-making cycle and effectively increases the ice production per unit time. After heat exchange, the cooling medium, having absorbed heat and vaporized, experiences a temperature increase and flows out through the cooling medium outlet 425, entering the condenser for heat dissipation and liquefaction, thus forming a complete and sustainable refrigeration cycle.

[0120] It is understood that the cooling medium flow channel 423 includes two sets of heat exchange channels. By dividing the complete flow channel into two sets, the flow path of the cooling medium can be planned more flexibly, making it easier to achieve full coverage of the entire surface of the spray evaporator 420. The two sets of heat exchange channels are arranged at intervals along the width direction of the spray evaporator 420. Each set of heat exchange channels includes multiple flow channel units 426. The multiple flow channel units 426 in the same set are connected sequentially along the length direction of the spray evaporator 420. The flow channel units 426 are U-shaped. In one set of heat exchange channels, the first flow channel unit 426 is connected to the cooling medium inlet 424, and the last flow channel unit 426 is connected to the first flow channel unit 426 in the other set of heat exchange channels. In the other set of heat exchange channels, the last flow channel unit 426 is connected to the cooling medium outlet 425. This series connection method constructs a complete, ultra-long "S"-shaped or serpentine flow channel that runs through the core area of ​​the spray evaporator 420, ensuring that the incoming low-temperature cooling medium can fully flow within the spray evaporator 420 and absorb heat, thus maximizing the utilization of the cooling capacity carried by the cooling medium. By using multiple U-shaped flow channel units 426 connected in series, the effective flow path and heat exchange area of ​​the cooling medium within the cooling medium flow channel 423 are increased, ensuring sufficient and efficient heat exchange between the cooling medium and the spray evaporator 420, thereby improving heat exchange efficiency and the overall cooling effect of the spray evaporator 420, ultimately resulting in faster ice-making speed and lower energy consumption.

[0121] Understandably, the ice-making equipment also includes a compressor, a refrigerant solenoid valve, a condenser, a dryer filter, and a capillary tube. The compressor outlet is connected to the condenser inlet and the first interface of the refrigerant solenoid valve, while the condenser outlet is connected to the dryer filter inlet. The spray evaporator 420 can be connected in series or in parallel with the first evaporator.

[0122] When the spray evaporator 420 is connected in series with the first evaporator, the inlet of the capillary tube is connected to the outlet of the dryer filter, the outlet of the capillary tube and the second interface of the refrigerant solenoid valve are both connected to the cooling medium inlet 424 of the spray evaporator 420, the cooling medium outlet 425 of the spray evaporator 420 is connected to the medium inlet 14 of the first evaporator, and the medium outlet 15 of the first evaporator is connected to the inlet of the compressor.

[0123] When the spray evaporator 420 is connected in parallel with the first evaporator, the ice-making equipment also includes a three-way reversing valve, and there are two capillary tubes. The inlet of the three-way reversing valve is connected to the outlet of the dryer filter. One outlet of the three-way reversing valve is connected to the cooling medium inlet 424 of the spray evaporator 420 through a capillary tube. The other outlet of the three-way reversing valve is connected to the medium inlet 14 of the first evaporator through another capillary tube. The second port of the refrigerant solenoid valve is connected to the cooling medium inlet 424 of the spray evaporator 420 and the medium inlet 14 of the first evaporator. The cooling medium outlet 425 of the spray evaporator 420 and the medium outlet 15 of the first evaporator are both connected to the inlet of the compressor.

[0124] The spray evaporator 420 and the first evaporator serve both freezing and heating / de-icing functions during the ice-making process. During ice making, the refrigerant solenoid valve is closed, and both the spray evaporator 420 and the first evaporator are used for refrigeration to freeze the water in their respective ice-making chambers into ice cubes. During de-icing, the refrigerant solenoid valve is open, and the high-temperature, high-pressure medium output from the compressor directly enters the interior of the spray evaporator 420 and the first evaporator. The increased temperature of the spray evaporator 420 and the first evaporator melts the surface of the ice cubes, causing them to separate from the spray evaporator 420 or the first evaporator, thus achieving de-icing.

[0125] In some embodiments of the present invention, the disturbance component 30 includes a drive mechanism 310 and a disturbance mechanism 320. The drive mechanism 310 is disposed outside the water box body 210, while the disturbance mechanism 320 is disposed inside the water inlet cavity 211. External placement of the drive mechanism 310 effectively prevents core drive components such as the motor from directly contacting the water, thus improving product safety and service life. A connection hole is provided on the water box body 210, through which the connecting shaft of the drive mechanism 310 passes and connects to the disturbance mechanism 320. The drive mechanism 310 is adapted to drive the disturbance mechanism 320 to move, and the disturbance mechanism 320 is adapted to drive the water in the water inlet cavity 211 to flow. By driving the water in the water inlet cavity 211 to flow, the water in the first ice-making cavity 221 circulates with the water in the ice-making cavity. When the water freezes, the gas and impurities discharged are immediately carried away by the flowing water, preventing them from freezing inside the ice crystals. This allows for the stable production of high-quality ice cubes that are almost bubble-free and crystal clear.

[0126] The ice-making equipment provided by the present invention drives the disturbance mechanism 320 to move through the drive mechanism 310. The disturbance mechanism 320 drives the water in the water inlet chamber 211 to flow, so that the water in the water inlet chamber 211 and the water in the first ice-making chamber 221 can flow and circulate fully with each other. During the process of water freezing into ice, the gas and impurities in the water will be carried away by the continuously flowing liquid water and will not be trapped in the ice crystals. Ultimately, this ensures that the ice blocks produced are free of air bubbles and are crystal clear, thus improving the quality of the ice blocks.

[0127] It is understandable that, such as Figure 1 and Figure 3 As shown, the drive mechanism 310 includes a drive motor, and the disturbance mechanism 320 includes a disturbance impeller. The disturbance impeller is directly mounted on the connecting shaft of the drive motor, and the drive motor is adapted to drive the disturbance impeller to rotate. During ice making, the drive motor drives the disturbance impeller to rotate stably, and the disturbance impeller then drives the water in the water inlet chamber 211 to flow. Through the disturbance holes, the water continuously washes the freezing interface of the first ice-making chamber 221, promoting full circulation between the water in the first ice-making chamber 221 and the water in the water inlet chamber 211. This continuous circulation can promptly remove the air and impurities that are released during the freezing process, preventing them from freezing inside the ice, thus fundamentally solving the problem of turbidity in the ice. The resulting ice has extremely high transparency and excellent quality.

[0128] It is also understood that the drive mechanism 310 includes a water pump and a connecting pipe. The water pump can be set inside or outside the water box body 210. The water pump inlet is connected to the water inlet chamber 211 through the connecting pipe, and the water pump outlet is connected to the first ice-making chamber 221 through the connecting pipe. During the ice-making process, the water pump continuously pumps the water in the water box body 210 through the connecting pipe and sprays or injects it onto the freezing surface of the first ice-making chamber 221, while the unfrozen water flows back into the water box body 210 through the turbulence hole, forming a complete closed loop.

[0129] Understandably, the drive mechanism 310 includes a linear drive component, and the disturbance mechanism 320 includes a disturbance pusher plate. The disturbance pusher plate is sleeved on the connecting shaft of the linear drive component. The linear drive component is adapted to drive the disturbance pusher plate to perform linear reciprocating motion. By precisely controlling the stroke and frequency of the linear drive component, a pulsating water flow can be generated. Compared with a single-direction rotating water flow, this reciprocating motion can more effectively agitate the water in the corners of the cavity. During ice making, the linear drive component drives the disturbance pusher plate to perform regular linear reciprocating motion. When the disturbance pusher plate moves, it alternately pushes and pulls the water in the water cavity 211, thereby driving it to flow. This process creates a continuous pressure difference between the water inlet cavity 211 and the first ice-making cavity 221, forcing the water to flow and circulate fully between the two cavities, ensuring that the final ice cube is pure inside and crystal clear in appearance, thus improving the quality and aesthetics of the ice cube.

[0130] It is understandable that, such as Figure 1 and Figure 3As shown, the water box assembly 20 also includes a base plate 21. The base plate 21 is a rectangular plate and is disposed on the side of the water box body 210 facing the first evaporator assembly 50, and is sealed to the water box body 210. The base plate 21 has through holes, and the inner shell 220 covers the corresponding through holes and is sealed to the base plate 21. This installation method makes the inner shell 220 a modular component that is easy to disassemble and assemble, providing a technical premise for diversifying the ice cube shape by replacing the inner shell 220 with different concave shapes. The base plate 21, the inner shell 220, and the water box body 210 cooperate to form an independent water inlet cavity 211. The formation of the water inlet cavity 211 can serve as a water flow buffer and distribution area, which helps to stabilize the water pressure and flow rate entering the first ice-making cavity 221. The inner shell 220 has a receiving cavity on the side facing the first evaporator assembly 50. After the water box assembly 20 is installed in place, the edge of the inner shell 220 contacts and seals with the upper surface of the first evaporator assembly 50.

[0131] Understandably, a snap-fit ​​portion is provided on the side of the through hole facing the first evaporator assembly 50, and this snap-fit ​​portion extends continuously along the entire edge of the through hole. Correspondingly, a first sealing groove is provided on the side of the inner shell 220 away from the first evaporator assembly 50, and this first sealing groove also extends completely along the edge of the inner shell 220, with its opening facing upward. The shape of the first sealing groove is similar to and matches the shape of the snap-fit ​​portion. During assembly, the snap-fit ​​portion can be precisely snapped into the first sealing groove and form a tight sealing fit with it. This snap-fit ​​fit method has the following advantages: on the one hand, it realizes the convenience of quick installation and disassembly between the inner shell 220 and the substrate 21 without tools. Users only need to press lightly to complete the fixation, optimizing the operating experience. On the other hand, through the tight engagement of the snap-fit ​​portion and the periphery of the sealing groove, a reliable annular seal is formed, which effectively prevents water in the water inlet chamber 211 from leaking from the joint gap between the inner shell 220 and the substrate 21, ensuring that all water is accurately guided to the first ice-making chamber 221, avoiding waste of water resources.

[0132] It is understood that the substrate 21 is provided with a limiting step 253 on the side away from the first evaporator assembly 50. Correspondingly, the edge of the inner shell 220 is provided with a sealing part on the side away from the first evaporator assembly 50, and a second sealing groove is provided on the side of the sealing part facing the first evaporator assembly 50. The opening of the second sealing groove faces downward, and the limiting step 253 is embedded in the second sealing groove and forms a sealing fit with the second sealing groove. This structure not only achieves a stable locking between components and prevents relative misalignment, but more importantly, it forms a tortuous, non-linear labyrinthine sealing path, forming a double sealing structure, which can effectively prevent water leakage in the water inlet chamber 211 when the water level is high or the pressure fluctuates.

[0133] Understandably, there are two inner shells 220, so two ice blocks can be made at the same time. The disturbance mechanism 320 is located between the two inner shells 220, so that a single disturbance mechanism 320 can act on two independent ice-making chambers at the same time. This not only simplifies the overall mechanical structure, reduces the number of parts and potential failure points, and lowers the manufacturing cost, but also generates a more symmetrical and uniform water flow to the disturbance holes on both sides, ensuring the consistency of the quality of the two ice blocks.

[0134] Understandably, the inner shell 220 is hemispherical, and it is provided with strip-shaped turbulence holes 222. The center of the strip-shaped turbulence holes 222 is located on the central axis of the inner shell 220, ensuring that water can enter from the apex or center of the ice block mold. This facilitates the formation of a uniform and symmetrical circulation path, which is the basis for constructing an efficient water circulation. The strip-shaped turbulence holes 222 of the first ice-making cavity 221 serve as the main path for water to enter the first ice-making cavity 221 from the water inlet cavity 211, while the turbulence holes serve as the main path for water to flow back from the first ice-making cavity 221 to the water inlet cavity 211. By clearly distinguishing the water inlet and outlet channels, an efficient circulation loop is constructed. Water flows in through the central strip-shaped turbulence hole 222, washes the first ice-making chamber 221, and then flows out through the surrounding turbulence holes. This design avoids short-circuiting or turbulence of the water flow, ensuring that the water in the entire first ice-making chamber 221 can be effectively replaced and renewed, thereby maximizing the efficiency of exhaust and impurity removal to produce high-quality transparent ice.

[0135] Understandably, this design, by setting multiple water outlet paths, ensures smooth and sufficient water flow from the first ice-making chamber 221 back to the inlet chamber 211, avoiding flow bottlenecks that might be caused by a single orifice, thus maintaining the stability and high efficiency of the entire circulation system. It places the return water path closest to the central disturbance mechanism 320, constructing the shortest and most direct circulation loop, reducing flow resistance and improving circulation efficiency. Simultaneously, the uniform distribution ensures that water is smoothly and synchronously drawn from the inner edge of the first ice-making chamber 221, avoiding the generation of local eddies or stagnant zones caused by uneven water output, ensuring a consistent water flow renewal rate throughout the first ice-making chamber 221. This is crucial for uniformly removing impurities and ensuring a high degree of consistency in the quality of the two ice blocks.

[0136] Understandably, the inner shell 220 is provided with a non-stick coating on the side facing the first ice-making cavity 221. This coating reduces the adhesion between the ice and the surface of the inner shell 220, thereby reducing the force required to remove the ice during the ice removal process. This not only protects the integrity of the ice and prevents it from cracking or scratching when it is removed, but also ensures that the final product ice has a smooth and perfect appearance.

[0137] Understandably, a sealing ring is installed inside the connection hole. This structure is key to achieving rotary sealing, reliably sealing the gap between the drive mechanism 310 connecting shaft and the water box body 210. This effectively prevents water in the inlet chamber 211 from leaking out through the connection hole, ensuring the watertightness of the equipment and avoiding safety hazards such as short circuits in external circuits or damage to the drive mechanism 310 caused by water leakage. The sealing ring is fitted around the outer circumference of the connecting shaft and seals with it, ensuring that even when the connecting shaft rotates or reciprocates, the sealing ring remains tightly attached to the surface of the shaft, forming a reliable dynamic watertight barrier. This ensures the sealing reliability and durability of the device during long-term operation, improving the overall safety level and service life of the product.

[0138] It is understandable that the inner shell 220 is made of a flexible material, and the pressing mechanism is set in the water box body 210. The pressing mechanism is adapted to squeeze the inner shell 220 to deform during ice removal so that the ice block is separated from the inner shell 220.

[0139] According to the ice-making equipment provided by the present invention, the inner shell 220 is made of a flexible material, allowing it to easily undergo recoverable deformation under external force. During the ice removal process, pressing the pressing mechanism by hand further compresses the flexible inner shell 220 under pressure, causing it to deform locally or entirely. This method of separating ice blocks through compression and deformation simplifies the overall mechanical structure, reducing manufacturing costs and achieving higher reliability and a longer service life due to the reduction of moving parts. Throughout the entire ice removal process, the pressing mechanism always acts on the outer wall of the inner shell 220, preventing direct contact between the pressing mechanism and the ice blocks inside the inner shell 220, thus ensuring the food-grade hygiene of the ice blocks.

[0140] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
