These pipes usually need to be routed around the mold shell, requiring additional grooves for assembly and fixation to achieve good heat transfer. This increases the number of assembly steps and production costs.

[0003] Therefore, it is necessary to improve the ice-making module of the ice-making device to reduce the production and assembly steps without affecting its ice-making efficiency. Utility Model Content

[0004] Regarding the existing ice-making devices mentioned above, their ice-making modules install pipes containing refrigerant on one side of the mold shell to cool the liquid water inside the mold shell. These pipes generally need to be routed around the mold shell, and the mold shell needs additional grooves for assembly and fixation to achieve good heat transfer. This increases the technical problems of production assembly processes and production costs. The technical solution adopted by this utility model to solve these problems is as follows:

[0005] An ice-making module includes a housing, which has an ice-making cavity on one side for making ice blocks, a cooling cavity on the other side for containing refrigerant, a water inlet channel communicating with the ice-making cavity, an input end for refrigerant to enter the cooling cavity, and an output end for refrigerant to exit the cooling cavity.

[0010] Furthermore, in some embodiments of this utility model, the guide end is provided with a second guide end that allows the refrigerant in the cooling chamber to move in a detour.

[0014] Furthermore, another objective of this invention is to provide an ice-making device, including the ice-making module described above.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention's ice-making module, by incorporating a cooling chamber for refrigerant storage, eliminates the need for complex grooving and additional machining of the casing, simplifying the production and assembly process, reducing the use of refrigerant piping, and effectively improving production and assembly efficiency.

[0021] Figure 5 for Figure 4 BB cross-sectional view.

[0022] Figure 6 for Figure 4 CC section view. Detailed Implementation

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 6 An ice-making module is shown, including a housing 1. The housing 1 has an ice-making cavity 2 located on one side for making ice blocks, a cooling cavity 3 located on the other side for containing refrigerant, a water inlet channel 4 communicating with the ice-making cavity 2, an input end 5 for refrigerant to enter the cooling cavity 3, and an output end 6 for refrigerant to exit the cooling cavity 3. The refrigerant transfers heat through the inner wall of the cooling cavity 3, thereby driving the liquid water in the ice-making cavity 2 to turn into solid ice.

[0025] Traditional ice-making devices require additional grooves in the mold shell to accommodate the winding pipes containing refrigerant, ensuring good heat transfer. This new ice-making module features a cooling chamber to hold the refrigerant, eliminating the need for complex grooving and other additional processing on the shell. This significantly simplifies the refrigerant piping layout during production and assembly, effectively improving efficiency. The refrigerant flows within the cooling chamber, directly exchanging heat with the liquid water in the ice-making chamber through the chamber's inner wall. The increased direct contact area between the refrigerant and the cooling chamber wall significantly enhances heat transfer efficiency, accelerating the conversion of liquid water into solid ice. The heat transferred from the refrigerant through the cooling chamber's inner wall provides a stable supply of cooling energy for the conversion of liquid water into solid ice, ensuring a stable and efficient ice-making process and guaranteeing a continuous output of high-quality ice.

[0026] Specifically, in some embodiments, water enters the ice-making chamber through an inlet channel, and the movement speed or volume of the water can be controlled by means of flow detection, pressure detection, etc., so as to ensure that the quality of ice blocks in the ice-making process is consistent.

[0027] The refrigerant is transferred through a path from the input end to the cooling chamber and then to the output end. Specifically, in some embodiments, the refrigerant can be circulated, undergoing a path change at the output end, and then moved back to the input end. This optimizes the heat transfer process, reduces refrigerant waste and energy consumption, and makes the ice-making process more environmentally friendly and energy-saving.

[0028] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, by reducing the steps of adding grooves to the mold shell and setting up complex and circuitous pipes, on the one hand, the processing costs in the production process are directly reduced, such as reducing the cost of equipment use and manual operation required for processes such as grooving; on the other hand, it also reduces the risk of increased costs due to scrap rate caused by complex processes, so that the overall production cost can be effectively controlled.

[0029] like Figures 1 to 3 An ice-making module is shown, wherein the housing 1 includes a first mold shell 7 and a second mold shell 8 that can be in an open or closed state relative to the first mold shell 7. The first mold shell 7 and the second mold shell 8 enclose an ice-making cavity 2. The cooling cavity 3 is located in the first mold shell 7. The water inlet channel 4 passes through the cooling cavity 3 along the outer wall of the first mold shell 7 and extends to the ice-making cavity 2.

[0030] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the water inlet channel passes through the cooling chamber, allowing the liquid water to begin being pre-cooled by the refrigerant before entering the ice-making chamber, thereby improving the overall heat transfer efficiency and helping to accelerate ice-making speed and increase ice-making efficiency. By integrating the cooling chamber and the water inlet channel within the first mold shell, additional pipes and connectors are reduced, simplifying the overall structure. This not only reduces manufacturing costs but also improves the reliability and durability of the product.

[0031] In addition, the design of the shell as a first mold shell and a second mold shell that can be opened and closed relative to it makes the assembly of the ice-making module more modular, improves the flexibility and convenience of production assembly, reduces assembly difficulty and error rate, and the second mold shell, which is easier to open and close than the first mold shell, allows users to easily remove ice cubes, improves the convenience of use, and also helps to keep the ice-making cavity clean and hygienic, making maintenance easier and improving the user experience.

[0032] like Figures 2 to 6 An ice-making module is shown, wherein the ice-making cavity 2 is provided with a first extension end 31 extending toward the cooling cavity 3, or the inner wall of the other side of the first mold shell 7 is provided with a second extension end extending into the ice-making cavity 2, and the water inlet channel 4 is located at the first extension end 31 or the second extension end.

[0033] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the provision of the first or second extension end allows the water flow to slow down when entering the ice-making chamber, reducing the impact on the inner wall of the ice-making chamber. When the water inlet channel is located at the first extension end extending towards the cooling chamber or the second extension end extending into the ice-making chamber, the water entering the ice-making chamber can be closer to the cooling source. Before the water has fully entered the main space of the ice-making chamber, it can come into contact with the low-temperature area in the cooling chamber and begin to cool down, thereby increasing the effective cooling time of the water and accelerating the transformation process of liquid water into solid ice, thereby improving ice-making efficiency and producing ice blocks in a shorter time.

[0034] Furthermore, placing the water inlet channel at the first or second extension end avoids the need for additional complex water inlet channel spaces in other parts of the ice-making chamber. This results in a more compact and rational internal spatial layout, helping to reduce the overall size of the ice-making module. Within limited equipment installation space, this allows for the integration of more functional modules, or increases the effective volume of the ice-making chamber within the same volume, thereby increasing the ice production capacity per cycle and improving the space utilization of the ice-making device. Compared to the traditional method of the water inlet pipes being routed from the outside of the ice-making chamber, placing the water inlet channel at the first or second extension end reduces the design complexity and number of components of independent water inlet pipes. This lowers the overall design difficulty and manufacturing cost of the ice-making module, while also reducing the risk of leakage due to excessive pipe connection points, thus improving the reliability and stability of the ice-making device.

[0035] Optionally, in some embodiments, a water pipe can be inserted into the water inlet channel so that an external water source can directly enter the ice-making chamber through the water inlet channel. This can be achieved by setting up an external water tank and using the transmission end of the water tank to engage with the water inlet channel, so that the water stored in the water tank can enter the ice-making chamber through the water inlet channel.

[0036] like Figures 1 to 6 The ice-making module shown has a cooling chamber 3 with a guide end 32, which allows the refrigerant to move from the input end 5 through the cooling chamber 3 to the output end 6.

[0037] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the guide end ensures that the refrigerant flows from the input end along a predetermined path through the cooling chamber until it reaches the output end. This avoids disordered eddies or stagnation of the refrigerant within the cooling chamber, allowing the refrigerant to make more thorough contact with the inner wall of the cooling chamber. By optimizing the refrigerant flow path, the guide end allows the refrigerant to stay in the cooling chamber for a longer time and has a larger contact area with the inner wall of the cooling chamber. Because the refrigerant can flow efficiently within the cooling chamber and exchange heat, the liquid water in the ice-making chamber can lose heat and freeze into ice more quickly.

[0038] Specifically, the guide end not only guides the refrigerant to flow evenly through the cooling chamber, resulting in a more uniform temperature distribution on the inner wall of the cooling chamber, but also enhances the structural stability of the cooling chamber. It can withstand the pressure generated by the refrigerant flow, reducing the risk of cooling chamber deformation and thus extending the service life of the ice-making module.

[0039] like Figures 3 to 6 An ice-making module is shown, wherein the cooling cavity 3 is provided with an input channel 33 communicating with the input end 5 and an output channel 34 communicating with the output end 6, and the guide end 32 is provided with a first guide end 321 separating the input channel 33 and the output channel 34. The input channel 33 and the output channel 34 are respectively located at the beginning and end of the cooling cavity 3, and the input end 5 and the output end 6 are respectively located on the same side of the first mold shell 7.

[0040] Furthermore, as a preferred embodiment of this utility model and not a limitation, by setting independent input and output channels separated by a first guide end, the refrigerant forms a movement path within the cooling chamber. Entering the cooling chamber from the input end via the input channel, completing heat exchange within the chamber, and then flowing out from the output end via the output channel, the refrigerant effectively avoids backflow issues within the cooling chamber, ensuring the refrigerant fully utilizes its cooling function, improving heat exchange efficiency, and thus accelerating ice-making speed. Optimizing the refrigerant flow path and improving heat transfer efficiency helps reduce energy consumption during the ice-making process. The first guide end not only separates the input and output channels but also enhances the structural stability of the cooling chamber; it can withstand the pressure generated during refrigerant flow, reducing the risk of cooling chamber deformation and thus extending the service life of the ice-making module.

[0041] Furthermore, the input and output channels are located at the beginning and end of the cooling chamber, respectively, and both ends are on the same side of the first mold shell. This layout allows the refrigerant to flow a longer distance within the cooling chamber, resulting in a larger contact area and longer contact time with the inner wall. The refrigerant can absorb heat more fully within the cooling chamber, causing the liquid water in the ice-making chamber to cool and solidify more rapidly. This improves the heat transfer performance of the entire ice-making module, contributing to the production of high-quality, well-formed ice. Connecting to an external refrigerant supply system is also more centralized and convenient, reducing the complexity and space required for piping, making the overall structure of the ice-making module more compact and improving space utilization.

[0042] like Figures 3 to 6 An ice-making module is shown, wherein the guide end 32 is provided with a second guide end 322 that allows the refrigerant in the cooling chamber 3 to move in a detour, and the second guide end 322 is provided with a plurality of avoidance ends 3221 that cooperate with the first extension end 31 or the second extension end, and the avoidance ends 3221 are arranged in an arc shape.

[0043] Furthermore, as a preferred embodiment of this utility model and not a limitation, the second guide end causes the refrigerant to move in a detour, greatly increasing the flow path length of the refrigerant within the cooling chamber. The refrigerant stays in the cooling chamber for a longer time, allowing for more sufficient heat exchange with the inner wall of the cooling chamber. This enables it to absorb more heat from the ice-making chamber, efficiently reducing the temperature of the liquid water within the ice-making chamber, accelerating the ice-making process, and improving the overall ice-making efficiency of the ice-making device.

[0044] Specifically, multiple arc-shaped clearance ends cooperate with the first or second extension end to guide the refrigerant to flow in a circuitous manner, while making the distribution of refrigerant in different areas of the cooling chamber more uniform. This uniform refrigerant distribution can ensure that the temperature in various parts of the cooling chamber is relatively consistent, thereby making the cooling process of the ice-making chamber more uniform and stable, and reducing ice quality problems caused by excessive local temperature differences.

[0045] Furthermore, the arc-shaped clearance end design effectively buffers the turning impact of the refrigerant during its meandering flow. When the refrigerant changes direction within the cooling chamber, the arc-shaped structure guides the refrigerant through a smooth transition, avoiding the impact force on the inner wall of the cooling chamber caused by abrupt changes. This reduces the risk of damage to the cooling chamber due to long-term impact, extends its service life, improves the overall reliability and stability of the ice-making device, and reduces downtime and maintenance costs caused by equipment failure. The arc-shaped clearance end also helps reduce noise and vibration generated during refrigerant flow. This design makes the ice-making module quieter and smoother during operation, improving the user experience.

[0046] Specifically, the multiple avoidance ends result in a wave-shaped arrangement of the second guide end. This guide end directs the refrigerant through a meandering path and coordinates with either the first or second extension end using the avoidance ends. Without increasing the volume of the cooling chamber, the first or second extension ends can be staggered, making full use of the internal space. This allows the refrigerant to achieve a more complex and efficient heat exchange path within a limited space, improving the space utilization of the cooling chamber and helping to enhance its ice-making performance while maintaining a compact overall size.

[0047] like Figures 3 to 6 An ice-making module is shown, wherein the cooling chamber 3 is provided with a sealing end 35 connected to the outside of the first extension end 31 or the second extension end.

[0048] Furthermore, as a preferred embodiment of this utility model and not a limitation, a stable heat exchange path helps maintain a stable temperature inside the ice-making cavity during the ice-making process. The sealed end can prevent external heat from interfering with the heat transfer process between the cooling cavity and the ice-making cavity, allowing the water temperature inside the ice-making cavity to drop steadily, thereby ensuring the quality and forming effect of the ice. Stable temperature control can reduce internal stress and air bubbles in the ice, resulting in higher quality ice.

[0049] Specifically, the sealing end is connected to the outside of the first or second extension end, effectively sealing any gaps that may exist between the cooling chamber and the ice-making chamber. On one hand, this reduces energy loss during heat transfer, helping to ensure efficient refrigerant flow and sufficient heat exchange within the cooling chamber, thereby improving ice-making efficiency. On the other hand, it prevents refrigerant from leaking into the ice-making chamber or into external water sources, thus affecting the quality and purity of the ice. Simultaneously, it prevents outside air and moisture from entering the cooling chamber, keeping the refrigerant clean and dry, and extending its service life.

[0050] In addition, the sealing end not only serves a sealing function but also enhances the structural connection between the cooling chamber and the ice-making chamber. It can withstand the pressure and vibration generated during the ice-making process, reducing the risk of mold shell deformation or cracking and improving the durability of the ice-making module.

[0051] like Figures 1 to 6 An ice-making module is shown, wherein the housing 1 is provided with a sealing housing 9, the sealing housing 9 and the first mold housing 7 enclose the cooling cavity 3, the sealing housing 9 is provided with a sealing housing opening 91, the sealing housing opening 91 allows external water to enter the ice-making cavity 2 through the first extension end 31 or the second extension end.

[0052] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the sealing shell and the first mold shell enclose a cooling cavity, effectively enhancing the sealing performance of the cooling cavity. The sealing shell significantly reduces the risk of refrigerant leakage, ensuring the stability and reliability of refrigerant circulation. The sealed cooling cavity prevents external impurities, dust, or moisture from entering, thereby protecting the components inside the cooling cavity from corrosion and damage. This reduces the maintenance and replacement work required due to external interference, ensuring the long-term stable operation of the ice-making device.

[0053] Optionally, in some embodiments, the second extension is located inside the sealed housing and extends into the ice-making cavity.

[0054] Specifically, the opening of the sealed shell allows external water to enter the ice-making chamber only through the first or second extension end, achieving precise control over the water inlet path. This prevents turbulence or leakage into other areas during water entry, ensuring the stability and reliability of the water inlet process. This improves the predictability and accuracy of the ice-making process, leading to better control over ice quality and output. The cooling chamber structure formed by the sealed shell and the first mold shell makes the overall ice-making device more compact, allowing for more functions or increased ice-making chamber volume within a limited space, meeting diverse user needs for spatial layout and ice production capacity. Furthermore, the combination of the sealed shell and the first mold shell facilitates modular production and assembly of the ice-making module. During production, the sealed shell and the first mold shell can be standardized for separate production, followed by assembly, improving production efficiency and product quality consistency. Simultaneously, the modular design makes component replacement easier during equipment maintenance or upgrades, reducing maintenance difficulty and costs, and improving the maintainability and scalability of the ice-making device.

[0055] like Figures 1 to 6 The ice-making module shown has an inner wall of the sealing housing 9 connected to the sealing end 35 and / or the guide end 32, respectively. The sealing housing 9, the sealing end 35 and the guide end 32 are all made of metal.

[0056] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the inner wall of the sealing shell is connected to the sealing end and / or the guide end, so that the various key parts of the cooling chamber are tightly integrated to form a more stable overall structure, which plays a role in preventing refrigerant from leaking into the ice-making chamber. The connection with the sealing shell completely seals the cooling chamber, preventing refrigerant from leaking from the cooling chamber into the external environment.

[0057] Specifically, the sealed housing is connected to the sealing end and / or the guide end, making the heat conduction path inside the cooling chamber more continuous and efficient. The refrigerant flows orderly within the cooling chamber through the guide end, and the generated cooling energy can be more effectively transferred to the ice-making chamber under the action of the sealing end. Simultaneously, the connection of the sealed housing ensures that heat is not lost during the transfer process due to structural gaps or discontinuities, thereby improving the heat exchange efficiency between the cooling chamber and the ice-making chamber, accelerating ice-making speed, and reducing the time and energy consumption required for ice making.

[0058] Furthermore, by connecting the inner wall of the sealed housing to the sealing end and / or the guide end, the structural stability of the entire ice-making module can be further enhanced, enabling it to withstand various pressures and vibrations generated during the ice-making process, reducing the risk of mold shell deformation or breakage, thereby extending the service life of the ice-making module.

[0059] Alternatively, the sealing end and the guide end can be integrally formed on the first mold shell, or they can be first connected to the first mold shell by welding.

[0060] Optionally, in some embodiments, the inner wall of the sealing housing can be fitted with the sealing end or the guide end by means of threaded connection, snap connection, magnetic connection, mortise and tenon connection, groove connection, integral molding, welding, etc. The sealing housing, sealing end, and guide end can be made of corrosion-resistant metal material or corrosion-resistant and low-temperature resistant plastic material, such as polytetrafluoroethylene, ultra-high molecular weight polyethylene, polyvinylidene fluoride, ethylene-tetrafluoroethylene copolymer, etc.

[0061] Optionally, in some embodiments, the sealing housing, sealing end, and guide end can all be made of stainless steel, copper, or aluminum.

[0062] Optionally, in some embodiments, the sealing housing is tightly connected to the sealing end.

[0063] Alternatively, in some embodiments, the sealing housing is tightly connected to the guide end.

[0064] Optionally, in some embodiments, the sealing housing is tightly connected to the sealing end and the guide end.

[0065] Specifically, this embodiment also includes an ice-making device, including the ice-making module as described above.

[0066] Furthermore, as a preferred embodiment of this utility model and not a limitation, the optimized shell structure, cooling chamber design, and water inlet channel layout in the ice-making module work together to significantly improve the ice-making efficiency of the ice-making device. The various parts of the ice-making module work in concert; for example, the design ensures good heat transfer uniformity between the cooling chamber and the ice-making chamber. The sealed shell and guide ends ensure uniform temperature distribution, reducing internal structural defects in the ice caused by temperature differences. The ice has a more uniform density and fewer bubbles and cracks, providing stable and high-quality ice products for applications requiring high ice quality, such as food preservation, beverage preparation, and medical experiments.

[0067] Furthermore, the modular design of the ice-making module makes the ice-making device more convenient to assemble during production. The accurate positioning and easy connection of each component reduce assembly steps and time, lower labor costs and the probability of errors, improve production efficiency, and facilitate large-scale manufacturing.

[0068] Example 1

[0069] like Figures 1 to 6An ice-making module is shown, including a housing 1. The housing 1 has an ice-making cavity 2 located on one side for making ice blocks, a cooling cavity 3 located on the other side for containing refrigerant, a water inlet channel 4 communicating with the ice-making cavity 2, an input end 5 for refrigerant to enter the cooling cavity 3, and an output end 6 for refrigerant to exit the cooling cavity 3. The refrigerant transfers heat through the inner wall of the cooling cavity 3, thereby driving the liquid water in the ice-making cavity 2 to turn into solid ice.

[0070] The housing 1 includes a first mold shell 7 and a second mold shell 8 that can be in an open or closed state relative to the first mold shell 7. The first mold shell 7 and the second mold shell 8 enclose an ice-making cavity 2. The cooling cavity 3 is located in the first mold shell 7. The water inlet channel 4 passes through the cooling cavity 3 along the outer wall of the first mold shell 7 and extends to the ice-making cavity 2.

[0071] The ice-making module of this invention features a cooling chamber 2 for holding the refrigerant, eliminating the need for complex grooving and other additional processing on the housing 1. This significantly simplifies the refrigerant piping layout during production and assembly, effectively improving efficiency. The refrigerant flows within the cooling chamber 3, directly exchanging heat with the liquid water in the ice-making chamber 2 through its inner wall. The increased direct contact area between the refrigerant and the inner wall of the ice-making chamber 2 significantly enhances heat transfer efficiency, accelerating the conversion of liquid water into solid ice. The heat transferred from the refrigerant through the inner wall of the cooling chamber 3 provides a stable supply of cooling energy for the conversion of liquid water into solid ice in the ice-making chamber 2, ensuring a stable and efficient ice-making process and guaranteeing a continuous output of high-quality ice.

The inner wall of the sealing housing 9 is connected to the sealing end 35 and guide end 32 by threaded connection and snap-fit ​​connection.

[0100] Example 15

[0101] Based on Embodiments 15 and 11, the following implementation method is provided: the sealing housing 9, the sealing end 35, and the guide end 32 are all made of aluminum metal. The inner wall of the sealing housing 9 is connected to the sealing end 35 and the guide end 32 respectively by welding.

[0102] Example 16

[0103] The difference between Embodiment Sixteen and Embodiment Fifteen is that the sealing housing 9, the sealing end 35, and the guide end 32 are all made of copper metal.

[0104] Example 17

[0105] The difference between Embodiment 17 and Embodiment 15 is that, unlike the integrally formed first mold shell, sealing end 35 and guide end 32, the sealing end 35 and guide end 32 in this embodiment are welded together. One end of the sealing end 35 and one end of the guide end 32 are first welded to the first mold shell 7, and then the sealing shell 9 is used to weld to the other end of the sealing end 35 and the other end of the guide end 32 respectively.

[0106] Example 18

[0107] Based on the above embodiments, Embodiment 18 also has the following implementation method: This embodiment further includes an ice-making device, including the ice-making module as described above.

[0108] The optimized shell structure 1, cooling chamber 3 design, and water inlet channel 4 layout in the ice-making module work together to significantly improve the ice-making efficiency of the device. The various parts of the ice-making module work in tandem; for example, the excellent heat transfer uniformity design between the cooling chamber 3 and the ice-making chamber 2, along with components such as the sealed shell 9 and guide end 32, ensure uniform temperature distribution, reducing internal structural defects in the ice caused by temperature differences. The ice has a more uniform density and fewer bubbles and cracks, providing stable and high-quality ice products for applications requiring high ice quality, such as food preservation, beverage preparation, and medical experiments.

[0109] Furthermore, the modular design of the ice-making module makes the ice-making device more convenient to assemble during production. Accurate positioning and easy connection of each component reduce assembly steps and time, lower labor costs and the probability of errors, improve production efficiency, and facilitate large-scale manufacturing and rapid market launch.

[0110] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
