Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of ice making, and in particular to an ice making device, an ice making apparatus and an ice making method. BACKGROUND

[0002] At present, the ice making apparatus of the related art mainly relies on mechanical refrigeration to realize the freezing of water, and the process usually includes stages of water cooling, nucleation, crystallization and ice block forming. However, the related art still has many problems: first, there is a large supercooling degree in the ice nucleus formation stage, which leads to uncontrollable nucleation time and affects the ice making efficiency; second, the nucleation process is difficult to trigger uniformly, resulting in uneven internal structure and poor transparency of the ice block; third, the ice making process has high energy consumption; in addition, due to the high failure rate of nucleation, the ice making failure phenomenon often occurs. Therefore, the ice making process of the related art has the problems of low efficiency, instability and high energy consumption. SUMMARY

[0003] In view of this, in order to solve the technical problems of low efficiency, instability and high energy consumption in the ice making process of the prior art, the present disclosure provides an ice making device, an ice making apparatus and an ice making method.

[0004] According to a first aspect of an embodiment of the present disclosure, an ice making device is provided, which comprises an ion storage bin, a mixed cooling bin, a deionization bin and an ice bin. The ion storage bin is used for storing an ionic liquid, the ion storage bin is in communication with the mixed cooling bin, the mixed cooling bin is in communication with an ice making water pipe, the deionization bin is in communication with the mixed cooling bin, and the ice bin is in communication with the deionization bin. In the ice making process of the ice making device, the ion storage bin provides the ionic liquid to the mixed cooling bin, the ice making water pipe provides the ice making water to the mixed cooling bin, the mixed cooling bin is used for transmitting the liquid with a first ion concentration to the deionization bin, the deionization bin is used for adsorbing the ions in the liquid input from the mixed cooling bin, and after the ion concentration of the liquid in the deionization bin reaches a second ion concentration, the deionization-processed liquid is transmitted to the ice bin, and the ice bin performs ice making on the liquid input from the deionization bin; wherein the ion concentration of the ionic liquid is greater than the ion concentration of the ice making water.

[0005] In an optional embodiment, The deionization bin comprises a deionization bin body and a capacitive deionization unit, and the capacitive deionization unit is fixedly connected with the bin body.

[0006] In an optional embodiment, The capacitor deionization unit includes a first electrode and a second electrode, which are located on opposite sides of the deionization chamber.

[0007] In one alternative implementation, Both the first electrode and the second electrode are constructed as porous electrodes.

[0008] In one alternative implementation, The deionization chamber is connected to the ion storage chamber, and the deionization chamber is also connected to the ice-making water pipe. In this process, after the deionized liquid in the deionization chamber is transferred to the ice-making chamber, the ice-making water pipe provides ice-making water to the deionization chamber. The ions adsorbed in the deionization chamber are desorbed and dissolved in the ice-making water to obtain ion cleaning liquid, which is then transferred to the ion storage chamber.

[0009] In one alternative implementation, The ice-making device includes an ion concentration pre-detection chamber, which includes a first sub-chamber and a second sub-chamber.

[0010] In one alternative implementation, The deionization chamber, the mixing and cooling chamber, and the ion concentration pre-detection chamber are arranged sequentially along a first direction, and the ion storage chamber and the mixing and cooling chamber are arranged along a second direction. In the first direction, the ion storage chamber at least partially overlaps with the deionization chamber, the mixing and cooling chamber, and the ion concentration pre-detection chamber. The first direction and the second direction are perpendicular to each other.

[0011] In one alternative implementation, The mixing and cooling chamber includes a third ion concentration detector and a first temperature sensor. The third ion concentration detector is used to detect the ion concentration of the liquid in the mixing and cooling chamber, and the first temperature sensor is used to detect the temperature of the mixing and cooling chamber. The deionization chamber includes a second temperature sensor, which is used to detect the temperature of the deionization chamber. When the ion concentration detected by the third ion concentration detector reaches the first ion concentration, and the temperature detected by the first temperature sensor and the temperature detected by the second temperature sensor are both within the first temperature range, the liquid in the mixing and cooling chamber is transferred to the deionization chamber.

[0012] In one alternative implementation, At least one fourth ion concentration detector is provided on each of the opposite sides of the deionization chamber to determine the ion concentration of the liquid in the deionization chamber.

After the liquid in the mixing and cooling chamber is transferred to the deionization chamber, the deionization chamber is controlled to deionize the liquid inside until the ion concentration of the liquid in the deionization chamber reaches the second ion concentration. Then, the liquid in the deionization chamber is transferred to the freezing chamber. After the liquid in the deionization chamber is transferred to the freezing chamber, the temperature of the freezing chamber is controlled to rise from the first temperature range to the second temperature range in order to freeze the liquid in the freezing chamber.

[0015] In one alternative implementation, The control of the deionization chamber to deionize the liquid inside includes: Before the ion concentration of the liquid in the deionization chamber reaches the second ion concentration, the deionization rate of the deionization chamber is adjusted based on the ion concentration of the liquid in the deionization chamber; wherein the deionization rate is positively correlated with the ion concentration of the liquid in the deionization chamber.

[0016] In one alternative implementation, The ice-making device includes an ion concentration pre-detection chamber, which includes a first sub-chamber and a second sub-chamber. The ion storage chamber is connected to the mixing and cooling chamber through the first sub-chamber, and the mixing and cooling chamber is connected to the ice-making water pipe through the second sub-chamber. The ice-making method includes: During the ice-making process, based on the ion concentration of the liquid in the first sub-compartment, the ion concentration of the liquid in the second sub-compartment, and the first ion concentration, the volume of ionic liquid and ice-making water transferred from the first sub-compartment and the second sub-compartment to the mixing and cooling chamber is controlled proportionally.

[0017] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: In this disclosure, by integrating an ion storage chamber, a mixing cooling chamber, a deionization chamber, and an ice-forming chamber, and by using ion concentration regulation to coordinate with the ice-forming process, uniform ice nucleus formation and efficient freezing are ensured. This has the advantages of achieving an efficient, stable, and energy-saving ice-making process by precisely regulating ion concentration, solving the problems of uncontrollable ice nucleus formation, uneven structure, and high energy consumption in traditional ice-making, and improving the quality and purity of ice blocks.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0038] To address the technical problems of inefficiency, instability, and high energy consumption in the existing ice-making process, this disclosure provides an ice-making apparatus, ice-making equipment, and ice-making method.

[0039] This invention integrates an ion storage chamber, a mixing and cooling chamber, a deionization chamber, and an ice-forming chamber, and utilizes ion concentration regulation to coordinate with the ice-forming process, ensuring uniform ice nucleus formation and efficient freezing. It achieves an efficient, stable, and energy-saving ice-making process by precisely controlling ion concentration, solving problems such as uncontrollable ice nucleus formation, uneven structure, and high energy consumption in traditional ice-making, and improving the quality and purity of ice.

[0040] In one exemplary embodiment, reference Figures 1 to 8 As shown, an ice-making apparatus, an ice-making device equipped with the ice-making apparatus, and an ice-making method applied to the ice-making apparatus are provided. In this embodiment, the ice-making apparatus may include an ion storage chamber 1, a mixing and cooling chamber 2, a deionization chamber 3, and an ice-forming chamber 4. These chambers may have independent physical structures and be connected by pipes or valves.

[0041] The ion storage chamber 1 stores ionic liquid and is connected to the mixing and cooling chamber 2, which is connected to the ice-making water pipe 30. The ionic liquid in the ion storage chamber 1 is introduced into the mixing and cooling chamber 2 during the ice-making process to adjust the ion concentration of the ice-making water. The mixing and cooling chamber 2 is a chamber in the ice-making device used to mix the ionic liquid and ice-making water (e.g., purified water) and to perform preliminary cooling on the mixed liquid. The deionization chamber 3 is connected to the mixing and cooling chamber 2. The deionization chamber 3 is a chamber in the ice-making device used to remove ions from the liquid. This chamber uses specific technical means to adsorb or separate ions from the liquid transported by the mixing and cooling chamber 2 to reduce the ion concentration of the liquid. The freezing chamber 4 is connected to the deionization chamber 3. The freezing chamber 4 is a chamber in the ice-making device used to freeze the deionized liquid. This chamber uses precise temperature control to promote the formation of ice blocks from the liquid.

[0042] For example, connectivity between chambers can be achieved through various fluid transfer components. For instance, flexible or rigid pipes can be used to connect the ion storage chamber 1 to the mixing and cooling chamber 2, equipped with flow meters and control valves to manually or via a preset program control the injection volume of the ionic liquid. The ice-making water pipe 30 can be an inlet directly connected to a water source, with water inflow controlled by a simple on / off valve. A transfer pump and check valve can be installed between the mixing and cooling chamber 2 and the deionization chamber 3 to ensure the liquid flows in a specified direction. A similar pumping mechanism can also be used between the deionization chamber 3 and the freezing chamber 4 to ensure the deionized liquid can smoothly enter the freezing area.

[0043] During the ice-making process of the ice-making device, the ion storage chamber 1 provides ionic liquid to the mixing and cooling chamber 2, and the ice-making water pipe 30 provides ice-making water to the mixing and cooling chamber 2. The mixing and cooling chamber 2 is used to transfer liquid with an ion concentration reaching a first ion concentration to the deionization chamber 3. The deionization chamber 3 is used to adsorb ions in the liquid input from the mixing and cooling chamber 2 until the ion concentration of the liquid in the deionization chamber 3 reaches a second ion concentration. Then, the deionized liquid is transferred to the freezing chamber 4, and the freezing chamber 4 freezes the liquid input from the deionization chamber 3. The ion concentration of the ionic liquid is greater than the ion concentration of the ice-making water.

[0044] During the ice-making process, if it is determined that the ion concentration in the liquid within the mixing and cooling chamber 2 reaches a first ion concentration, and the temperatures of both the deionization chamber 3 and the mixing and cooling chamber 2 reach a first temperature range, the liquid in the mixing and cooling chamber 2 is controlled to be transferred to the deionization chamber 3. This control logic ensures that the liquid is only transferred when specific ion concentration and temperature conditions are met, thereby optimizing the subsequent deionization effect.

[0045] The mixing and cooling chamber 2 may include a third ion concentration detector 103 and a first temperature sensor 105. The third ion concentration detector 103 is used to detect the ion concentration of the liquid in the mixing and cooling chamber 2, and the first temperature sensor 105 is used to detect the temperature of the mixing and cooling chamber 2. The deionization chamber 3 includes a second temperature sensor 106, which is used to detect the temperature of the deionization chamber 3.

[0046] When the ion concentration detected by the third ion concentration detector 103 reaches the first ion concentration, and the temperature detected by the first temperature sensor 105 and the temperature detected by the second temperature sensor 106 are both within the first temperature range, the liquid in the mixing and cooling chamber 2 is transferred to the deionization chamber 3.

[0047] It should be noted that the first ion concentration and the first temperature range can be set according to actual needs, and their specific values ​​are not limited.

[0048] In this process, after the liquid in the mixing and cooling chamber 2 is transferred to the deionization chamber 3, the deionization chamber 3 is controlled to deionize the liquid inside until the ion concentration of the liquid in the deionization chamber 3 reaches a second ion concentration. Then, the liquid in the deionization chamber 3 is transferred to the freezing chamber 4. At this time, the liquid is in a supercooled state.

[0049] It should be noted that the second ion concentration can be set according to the actual situation and is not limited thereto. However, the liquid at the second ion concentration is in a supercooled state within the first temperature range.

[0050] In this process, after the liquid in the deionization chamber 3 is transferred to the freezing chamber 4, the temperature of the freezing chamber 4 is controlled to rise from the first temperature range to the second temperature range, thereby freezing the liquid inside the freezing chamber 4. The subcooled liquid with the second ion concentration enters the freezing chamber 4 through the subcooled liquid inlet 60. Initially, the temperatures of the freezing chamber 4, deionization chamber 3, and mixing cooling chamber 2 are the same and all within the first temperature range. After the liquid enters the freezing chamber 4, the temperature of the freezing chamber 4 can be slowly raised to the second temperature range, breaking the subcooled state of the liquid and causing it to freeze rapidly.

[0051] This embodiment integrates an ion storage chamber 1, a mixing and cooling chamber 2, a deionization chamber 3, and an ice-forming chamber 4, and utilizes ion concentration regulation to coordinate with the ice-forming process, ensuring uniform ice nucleus formation and efficient freezing. It has the advantages of achieving an efficient, stable, and energy-saving ice-making process by precisely controlling ion concentration and temperature, solving problems such as uncontrollable ice nucleus formation, uneven structure, and high energy consumption in traditional ice-making, and improving the quality and purity of ice blocks.

[0052] In one exemplary embodiment, reference Figure 1 , Figure 6 and Figure 7 As shown, an ice-making apparatus, an ice-making device equipped with the ice-making apparatus, and an ice-making method applied to the ice-making apparatus are provided. In this embodiment, the deionization chamber 3 includes a deionization chamber body 31 and a capacitive deionization unit 32, the capacitive deionization unit 32 being fixedly connected to the chamber body. The capacitive deionization (CDI) unit refers to the core component in the deionization chamber 3 that realizes the ion adsorption function. This unit utilizes the electrochemical effect of the electrode surface to capture ions in the liquid through electrostatic adsorption.

[0053] It should be noted that capacitive deionization technology utilizes the double electric layer formed on the electrode surface when an electric current is applied to capture ions (such as sodium and chlorine) in the water through electrostatic adsorption, thereby achieving desalination. The ions are released after the power is turned off, and the electrode can be regenerated and reused.

[0054] The capacitive deionization unit 32 includes a first electrode 321 and a second electrode 322. The first electrode 321 and the second electrode 322 are two key components of the capacitive deionization unit 32, which form an electric field when energized to adsorb charged ions in the liquid. The first electrode 321 and the second electrode 322 are located on opposite sides of the deionization chamber 31. For example, the first electrode 321 and the second electrode 322 can be the upper and lower sides of the deionization chamber 31 when in use, respectively, and the first electrode 321 and the second electrode 322 are located inside the deionization chamber to contact the liquid inside, thereby achieving the adsorption of ions in the liquid.

[0055] Both the first electrode 321 and the second electrode 322 are constructed as porous electrodes, such as activated carbon, in order to increase the contact area between the electrode and the liquid, thereby improving the efficiency and capacity of ion adsorption.

[0056] Traditional ice-making processes are prone to producing impurity crystals when the water quality is poor, affecting the quality of the ice. This embodiment, however, utilizes capacitive deionization technology to effectively remove impurity ions from the water, fundamentally solving the problem of impurity crystallization and ensuring the purity and transparency of the ice. This deionization process is not available in traditional mechanical refrigeration ice machines, significantly improving the quality and food safety of the ice.

[0057] In addition, in this embodiment, at least one fourth ion concentration detector 104 is respectively provided on both opposite sides of the deionization chamber 3 to determine the ion concentration of the liquid inside the deionization chamber 3. For example, the average ion concentration detected by all the fourth ion concentration detectors 104 can be used as the ion concentration of the liquid inside the deionization chamber 3 (which can be denoted as C6). By acquiring real-time ion concentration data of the liquid at different locations inside the deionization chamber 3, this embodiment can provide more comprehensive and accurate ion concentration distribution information, effectively compensating for the monitoring blind spots or local concentration differences that may exist in a single detector, and effectively improving the reliability of ion concentration detection.

[0058] Specifically, during the deionization process of the deionization chamber 3 on the liquid within it, the deionization rate of the deionization chamber 3 is adjusted based on the ion concentration of the liquid within the chamber 3 before the ion concentration reaches the second ion concentration. The deionization rate is positively correlated with the ion concentration of the liquid within the chamber 3. This means that when the detected ion concentration is high, the system increases the deionization rate to accelerate ion removal; conversely, when the ion concentration is low, the system decreases the deionization rate to optimize energy consumption and avoid over-processing.

[0059] This embodiment effectively solves the problem of inaccurate deionization rate adjustment caused by incomplete ion concentration monitoring. By utilizing multiple fourth ion concentration detectors 104 positioned on opposite sides of the deionization chamber 3, this embodiment can acquire more comprehensive real-time ion concentration distribution information, thereby avoiding misjudgments caused by local concentration differences. Based on this precise real-time concentration data, the deionization rate is dynamically adjusted, allowing the deionization process to be optimized according to the actual ion load. This enables efficient ion removal at high concentrations and refined processing at low concentrations, significantly improving deionization efficiency. This refined control ensures that the liquid ion concentration entering the freezing chamber 4 remains stable at the second ion concentration, providing high-quality pure water for the subsequent freezing process. Ultimately, this results in ice cubes with higher uniformity and transparency, effectively reducing energy consumption in the ice-making process and improving overall ice-making efficiency.

[0060] In one exemplary embodiment, reference Figure 1 , Figure 3 and Figure 6 As shown, an ice-making apparatus, an ice-making device equipped with the ice-making apparatus, and an ice-making method applied to the ice-making apparatus are provided. In this embodiment, the deionization chamber 3 is connected to the ion storage chamber 1, and the deionization chamber 3 is connected to the ice-making water pipe 30.

[0061] In this process, after the deionized liquid in the deion chamber 3 is transferred to the ice-forming chamber 4, the ice-making water pipe 30 provides ice-making water to the deion chamber 3. The ions adsorbed in the deion chamber 3 are desorbed and dissolved in the ice-making water to obtain ion cleaning liquid. The ion cleaning liquid is then transferred to the ion storage chamber 1 to realize the recycling of ion liquid.

[0062] In this embodiment, by connecting the deionization chamber 3 with the ion storage chamber 1 and the ice-making water pipe 30, the regeneration of the electrode in the deionization chamber 3 and the recycling of the ionic liquid are achieved. During the ice-making process, after the deionization chamber 3 completes the deionization treatment of the liquid input from the mixing and cooling chamber 2 and transfers the liquid with an ion concentration reaching a second ion concentration to the freezing chamber 4, a cleaning and regeneration mechanism is introduced to address the problem of ion accumulation on the electrodes. The deionization chamber 3 is connected to the ice-making water pipe 30, allowing ice-making water to flow into the deionization chamber 3 at specific times. When the liquid in the deionization chamber 3 is transferred to the freezing chamber 4, the control system triggers the ice-making water pipe 30 to supply ice-making water to the deionization chamber 3. At this time, the capacitive deionization unit 32 in the deionization chamber 3 performs a desorption operation, causing the ions previously adsorbed on the first electrode 321 and the second electrode 322 to be released from the electrode surface and dissolved into the newly introduced ice-making water. Thus, the ice-making water becomes an ion-cleaning liquid with a high ion concentration. Subsequently, the channel connecting the deionization chamber 3 and the ion storage chamber 1 is activated, and the ion cleaning liquid is transferred to the ion storage chamber 1 through this channel. In this way, not only is the electrode of the deionization chamber 3 effectively regenerated and its deionization capacity restored, but the ion-rich liquid generated during the cleaning process is also recovered to the ion storage chamber 1, avoiding waste of ion resources and ensuring a continuous supply and recycling of the ion liquid. The entire process takes place between ice-making cycles, ensuring the continuous and efficient operation of the ice-making device.

[0063] In one exemplary embodiment, reference Figure 1 , Figure 3 , Figure 9 and Figure 10As shown, an ice-making apparatus, an ice-making device equipped with the ice-making apparatus, and an ice-making method applied to the ice-making apparatus are provided. In this embodiment, the ice-making apparatus includes an ion concentration pre-detection chamber 5, which is a structure specifically designed for pre-detecting and adjusting the ion concentration of a liquid before mixing. It can be a single physical cavity with internal partitions, or a modular structure composed of multiple independent but functionally interconnected sub-units.

[0064] The ion concentration pre-detection chamber 5 may include a first sub-chamber 51 and a second sub-chamber 52. The ion storage chamber 1 is connected to the mixing and cooling chamber 2 through the first sub-chamber 51, and the mixing and cooling chamber 2 is connected to the ice-making water pipe 30 through the second sub-chamber 52. That is, the first sub-chamber 51 and the second sub-chamber 52 are used to temporarily store ionic liquid and ice-making water, respectively.

[0065] The first sub-compartment 51 is equipped with a first ion concentration detector 101 for detecting the ion concentration of the ionic liquid input from the ion storage chamber 1 to the first sub-compartment 51; the second sub-compartment 52 is equipped with a second ion concentration detector 102 for detecting the ion concentration of the liquid input from the ice-making water pipe 30 to the second sub-compartment 52.

[0066] During the ice-making process, the volume of ionic liquid and ice-making water transferred from the first sub-compartment to the mixing cooling chamber 2 is controlled proportionally based on the ion concentration of the liquid in the first sub-compartment, the ion concentration of the liquid in the second sub-compartment, and the first ion concentration.

[0067] In some embodiments, the ionic liquid in the ion storage chamber 1 first enters the first sub-chamber 51, while the ice-making water in the ice-making water pipe 30 enters the second sub-chamber 52. Within their respective sub-chambers, the first ion concentration detector 101 and the second ion concentration detector 102 respectively monitor the current ion concentrations of the ionic liquid and the ice-making water in real time. This real-time monitoring data is then transmitted to the control unit of the ice-making device. Based on a preset target first ion concentration and in conjunction with the real-time ion concentration data obtained from the first and second ion concentration detectors 101 and 102, the control unit accurately calculates the required mixing ratio of the ionic liquid and the ice-making water. Subsequently, the control unit drives the corresponding flow control device (e.g., a proportional valve or metering pump) to precisely transfer the ionic liquid in the first sub-chamber 51 and the ice-making water in the second sub-chamber 52 to the mixing and cooling chamber 2 according to the calculated ratio. In this way, it is ensured that the liquids entering the mixing and cooling chamber 2 are precisely proportioned according to their respective ion concentrations before mixing, thereby ensuring that the liquids in the mixing and cooling chamber 2 stably reach the preset first ion concentration. This precise concentration control is crucial for the subsequent ice-making process. During the ice-making process, the liquid in the mixing and cooling chamber 2 is only transferred to the deionization chamber 3 when the ion concentration reaches a first ion concentration and the temperature is within a first temperature range. If the ion concentration of the mixed liquid is unstable, it will directly affect the deionization efficiency of the deionization chamber 3 and the freezing effect of the freezing chamber 4. This implementation method, by performing precise concentration pre-detection and ratio control before mixing, provides stable initial conditions for the entire ice-making process, significantly improving the stability and efficiency of ice making.

[0068] This embodiment effectively solves the problem of unstable ion concentration in mixed liquids caused by the lack of real-time detection and precise control of input liquid ion concentration in traditional ice-making processes. By setting up an ion concentration pre-detection chamber 5 before the mixing and cooling chamber 2, and using the first sub-chamber 51 and the second sub-chamber 52 to independently detect the ion concentration of the ionic liquid and the ice-making water, accurate concentration information of the two input liquids can be obtained in real time. Based on this, and using these real-time concentration data and a preset first ion concentration, the transfer volume of the two liquids to the mixing and cooling chamber 2 is precisely controlled proportionally, thereby ensuring that the liquid in the mixing and cooling chamber 2 can stably reach the target first ion concentration. This precise concentration pre-control significantly improves the stability of the ion concentration of the mixed liquid, providing more consistent and predictable input conditions for the subsequent deionization process in the deionization chamber 3, and avoiding a decrease in deionization efficiency due to concentration fluctuations. At the same time, the stable ion concentration also provides more optimized initial conditions for the freezing process in the freezing chamber 4, which helps to achieve more controllable and uniform ice nucleus formation and crystallization, thereby improving ice-making efficiency and ice quality. Overall, this solution provides a solid guarantee for the stable operation and efficient ice making of the entire ice-making unit through meticulous management of the liquid mixing process.

[0069] In one exemplary embodiment, reference Figure 1 and Figure 2 As shown, an ice-making apparatus, an ice-making device equipped with the ice-making apparatus, and an ice-making method applied to the ice-making apparatus are provided. In this embodiment, the off-duty storage chamber 1, the deionization chamber 3, the mixing and cooling chamber 2, the ion concentration pre-detection chamber 5, and the freezing chamber 4 are all arranged on the same plane, that is, the bottom surfaces of the above-mentioned chambers can be located on the same plane and are connected as needed to realize the transfer of liquid.

[0070] The deionization chamber 3, the mixing and cooling chamber 2, and the ion concentration pre-detection chamber 5 are arranged sequentially along the first direction, meaning these three functional units are linearly arranged along a main axis in a specific spatial order. This arrangement aims to optimize the liquid transport path between different processing stages, reduce pipe length and bends, thereby reducing fluid resistance and improving transport efficiency.

[0071] The ion storage chamber 1 and the mixing and cooling chamber 2 are arranged along a second direction, that is, the ion storage chamber 1 and the mixing and cooling chamber 2 are positioned in space along an axis different from the first direction. This arrangement aims to provide a direct and efficient supply path for the ionic liquid, avoid complex pipeline layouts, and ensure that the ionic liquid can be stably and quickly delivered to the mixing and cooling chamber 2.

[0072] Furthermore, in the first direction, the ion storage chamber 1 at least partially overlaps with the deionization chamber 3, the mixing and cooling chamber 2, and the ion concentration pre-detection chamber 5. That is, the projection range of the ion storage chamber 1 in the first direction intersects with the projection ranges of the deionization chamber 3, the mixing and cooling chamber 2, and the ion concentration pre-detection chamber 5 in the first direction. This overlapping design aims to maximize space utilization by partially stacking components with different functions in space, thereby reducing the overall volume of the ice-making device.

[0073] In this configuration, the first and second directions are perpendicular to each other. This perpendicular relationship helps to form a compact grid-like or three-dimensional intersecting layout, further optimizing space utilization and reducing mutual interference between components, making the overall device structure more stable and integrated. It should be noted that the first and second directions can also be set to be non-perpendicular depending on the actual situation; this is not a limitation.

[0074] This embodiment, through the aforementioned layout scheme, achieves a more compact and rational arrangement of the entire ice-making device, effectively solving the problems of large device size and complex connecting pipes. This optimized layout significantly reduces fluid transmission paths and lowers pipe resistance, thereby reducing energy loss during the ice-making process. Simultaneously, the simplified connection structure improves operational convenience and system reliability. Ultimately, the ice-making device achieves a smaller size and lower energy consumption while maintaining high ice-making efficiency.

[0075] In one exemplary embodiment, reference Figures 1 to 10 As shown, an ice-making device and method are provided. This ice-making method is a highly efficient method based on ion concentration regulation and capacitive deionization technology. Its core lies in achieving controllable subcooling and controllable crystallization by regulating the ion concentration in water, thereby significantly improving ice-making efficiency and ice quality. This ice-making method is applicable to various commercial and household ice-making devices, such as built-in ice makers in refrigerators, stand-alone ice makers, and commercial ice production equipment, and is particularly suitable for scenarios with high requirements for ice quality, energy consumption control, and food safety.

[0076] This ice-making method relies on an integrated ice-making system, which may include an ion concentration control module, a capacitive deionization (CDI) unit, a temperature-concentration coordinated control system, an ice-making water circuit system, and a cooling integrated module. This ice-making system can achieve fully automated control of the entire process, from water cooling, ion control, supercooling establishment, controlled crystallization to ice block formation, through the coordinated operation of these multiple modules.

[0077] In this embodiment, the ice-making device may include an ion storage chamber 1, an ion concentration pre-detection chamber 5, a mixing and cooling chamber 2, a deionization chamber 3, and an ice-forming chamber 4. The deionization chamber 3 may include a capacitor deionization unit 32, that is, the deionization chamber 3 may also be referred to as a capacitor deionization chamber 3.

[0078] In this ice-making equipment, the ion storage chamber 1 stores a high-concentration ionic liquid. The specific ion concentration of the ionic liquid can be set according to actual needs and is not limited. However, the ion concentration of this ionic liquid is higher than that of the water used for ice making. The main component of this ionic liquid is water, and the dissolved ions in the water may include sodium ions, potassium ions, chloride ions, etc. The function of this high-concentration ionic liquid is to increase the ion concentration in ordinary ice-making water, thereby lowering the freezing point. The high-concentration ionic liquid is output from the ionic liquid output pipe 20 and recovered from the ion cleaning liquid recovery port.

[0079] Ordinary ice-making water and high-concentration ionic liquid enter the ion concentration pre-detection chamber 5 through the ice-making water pipe 30 and the ionic liquid inlet 10, respectively. That is, the ion storage chamber 1 is connected to the ion liquid inlet 10 of the ion concentration pre-detection chamber 5 through the ionic liquid outlet pipe 20, thereby transferring the high-concentration ionic liquid stored therein to the ion concentration pre-detection chamber 5.

[0080] The ion concentration pre-detection chamber 5 may include a first sub-chamber 51 and a second sub-chamber 52, which are independent of each other. An ion liquid inlet 10 is located in the first sub-chamber 51, meaning the ion storage chamber 1 is connected to the first sub-chamber 51, providing a high concentration of ion liquid to the first sub-chamber 51. An ice-making water pipe 30 is connected to the second sub-chamber 52, providing ordinary ice-making water to the second sub-chamber 52. The ion concentration of the ordinary ice-making water is lower than the ion concentration of the aforementioned ion liquid.

[0081] The first sub-compartment 51 is equipped with a first ion concentration detector 101, which is used to detect the ion concentration (which can be denoted as C1) of the liquid in the first sub-compartment 51, that is, the ion concentration of the liquid input from the ion storage chamber 1 to the ion concentration pre-detection chamber 5. The second sub-compartment 52 is equipped with a second ion concentration detector 102, which is used to detect the ion concentration (which can be denoted as C2) of the liquid in the second sub-compartment 52, that is, the ion concentration of the liquid input from the ice-making water pipe 30 to the ion concentration pre-detection chamber 5.

[0082] In this embodiment, based on the ion concentrations C1 and C2 detected by the first ion concentration detector 101 and the second ion concentration detector 102, a certain volume of high-concentration ionic liquid and ordinary ice-making water are respectively controlled to enter the mixing and cooling chamber 2. Wherein, CA = (C1V1 + C2V2) / (V1 + V2), CA is the first ion concentration, and V1 and V2 are the volumes of the ionic liquid and the ice-making water, respectively.

[0083] The ionic liquid and ice-making water are input from the high-concentration liquid inlet 40 and low-concentration liquid inlet 50 on the mixing and cooling chamber 2, respectively. After the two liquids are mixed in the mixing and cooling chamber 2, the ion concentration (which can be denoted as C3) of the mixed liquid can be detected by the third ion concentration detector 103 in the mixing and cooling chamber 2 to see if it reaches the first ion concentration CA. The first ion concentration can be set according to actual needs, and its specific value is not limited. After the ion concentration of the liquid in the mixing and cooling chamber 2 reaches the first ion concentration CA, the refrigeration system can be controlled to cool the mixing and cooling chamber 2, reducing its temperature to within a first temperature range (which can be denoted as t1), where t1 is 0.5℃-1℃ above the condensation point. The cooled liquid enters the deionization chamber 3 through the low-temperature liquid transfer port.

[0084] The deionization chamber 3 and the mixing and cooling chamber 2 maintain the same temperature. A first temperature sensor 105 is installed in the mixing and cooling chamber 2, and a second temperature sensor 106 is installed in the deionization chamber 3. When the temperatures detected by both are the same, the liquid in the mixing and cooling chamber 2 can be introduced into the deionization chamber 3. After the low-temperature mixed liquid enters the deionization chamber 3, it supplies power to the electrodes (including the first electrode 321 and the second electrode 322) of the capacitive deionization unit 32 within the deionization chamber 3, using a certain deionization rate (which can be denoted as V) to remove anions and cations from the mixed liquid. It should be noted that the first electrode 321 and the second electrode 322 can be constructed as porous electrodes, for example, they can be activated carbon.

[0085] The freezing point of the mixed liquid is related to its ion concentration; as the ion concentration decreases, the freezing point increases. Therefore, two fourth ion concentration detectors 104 are used before and after the deionization chamber 3. The average ion concentration detected by all the fourth ion concentration detectors 104 can be taken as the ion concentration of the liquid in the deionization chamber 3 (which can be denoted as C6).

[0086] It should be noted that as the ion concentration of the liquid decreases, the freezing point rises, while the liquid temperature remains constant, and the liquid enters a supercooled state. At this point, the ion concentration drops rapidly, easily breaking the supercooled state and causing the liquid to freeze quickly. Therefore, the deionization rate V is not a fixed value, but decreases as the ion concentration decreases. That is, the deionization rate is positively correlated with the ion concentration of the liquid in the deionization chamber 3. When the ion concentration C6 in the deionization chamber 3 drops to the second ion concentration CB, the ion removal rate V decreases to 0, and the electrode no longer adsorbs ions.

[0087] The subcooled liquid with the second ion concentration is discharged through the subcooled liquid outlet of the deionization chamber 3 and then enters the freezing chamber 4 through the subcooled liquid inlet 60. Initially, the temperatures of the freezing chamber 4, deionization chamber 3, and mixing cooling chamber 2 are the same and all within the first temperature range. After the liquid enters the freezing chamber 4, the temperature of the freezing chamber 4 can slowly rise to the second temperature range, breaking the subcooled state of the liquid and causing it to freeze rapidly. After freezing, the temperature inside the freezing chamber 4 begins to drop and stabilizes again within the first temperature range.

[0088] After the above process is completed, ions will accumulate on the electrodes of the deion chamber 3. These ions need to be desorbed and reused. Therefore, when ice making is not required, ice-making water can be introduced into the deion chamber 3 through the ice-making water pipe 30 and reverse-current applied to the electrodes. The ions adsorbed on them will be desorbed back into the liquid and then returned to the ion storage chamber 1 through the ion cleaning liquid discharge port 70 of the deion chamber 3 and the ion cleaning liquid recovery port 80 of the ion storage chamber 1.

[0089] In this embodiment, after ice making is started, a high-concentration ionic liquid is output from the ion storage chamber 1 and enters the first sub-chamber 51 of the ion concentration pre-detection chamber 5. Ordinary ice-making water (e.g., purified water) enters the second sub-chamber 52 of the ion concentration pre-detection chamber 5 from the ice-making water pipe 30. A first ion detector detects the ion concentration C1 of the liquid in the first sub-chamber 51, and a second ion detector detects the ion concentration C2 in the second sub-chamber 52. Then, based on C1, C2, and the first ion concentration CA, ordinary ice-making water and high-concentration ionic liquid are proportionally input into the mixing and cooling chamber 2, and the ion concentration C3 of the mixed liquid in the mixing and cooling chamber 2 is detected. Is C3 equal to CA? If C3 is not equal to CA, mixing and adjustment continue. If C3 is equal to CA, proceed to the next step. That is, the mixing and cooling chamber 2 is cooled down to 0.5℃–1℃ above the condensation point of the liquid (i.e., the first temperature range t1). Simultaneously, the temperature of the deionization chamber 3 is also reduced to t1, and then the low-temperature mixture is sent to the deionization chamber 3. The electrodes of deionization chamber 3 are energized to begin ion removal. During ion removal, the ion concentration of the liquid in deionization chamber 3 is detected by a fourth ion detector within deionization chamber 3, and the average ion concentration detected by all fourth ion concentration detectors 104 is taken as the ion concentration C6 of the liquid in deionization chamber 3. It is then determined whether C6 has decreased to the second ion concentration CB. If C6 has not reached CB, ions in the liquid continue to be removed at an adjustable deionization rate V (in this embodiment, V ranges from 0 mmol / (L·min) to 1 mmol / (L·min)). If C6 reaches CB, power supply to the electrodes is stopped, and the deionization rate V decreases to 0. Then, a supercooled liquid with an ion concentration of CB is introduced into ice-freezing chamber 4. It should be noted that the initial temperature of ice-freezing chamber 4 is also within the first temperature range (i.e., the same as the temperature of the upstream deionization chamber 3). When crystallization is triggered, the temperature of ice-freezing chamber 4 can be slowly increased to 0.5℃–1℃ above the condensation point of the liquid at this time (i.e., the second temperature range t2). The supercooled state of the liquid is broken, and the liquid quickly freezes. After freezing is complete, the temperature of the ice-freezing chamber 4 can drop and stabilize back to the first temperature range. Ice blocks are formed, and the ice-making equipment is ready for the next cycle.

[0090] It should be noted that both CA and CB can be set according to the actual situation, and their specific values ​​are not limited. However, generally, both CA and CB are less than the ion concentration of the ionic liquid, and CA is greater than the ion concentration of the water used for ice making, while CB is less than CA. t2 is 0.5℃-1℃ above the condensation point when the ion concentration is CB. A higher ion concentration results in a lower condensation point; therefore, the condensation point with an initial ion concentration of CA is recorded as the first condensation point, and the condensation point with an ion concentration of CB is recorded as the second condensation point. The first condensation point is less than the second condensation point. t1 is 0.5℃-1℃ higher than the first condensation point. After deionization, the condensation point of the liquid rises above t1; therefore, the second condensation point is higher than t1, and the liquid is in a supercooled state at this point. The temperature rises to t2, breaking the supercooling; therefore, t2 is higher than the second condensation point and also higher than t1.

[0091] This embodiment addresses the technical problems of uncontrollable ice nucleus formation, low ice-making efficiency, poor ice quality, high energy consumption, and high food safety risks in related ice-making technologies. This embodiment combines ion concentration regulation with capacitive deionization technology to achieve a controlled transformation of water from a supercooled state to a crystalline state, thereby improving ice-making efficiency and ice quality. Specifically, the ion concentration regulation module adds ions to the water during the initial cooling stage, lowering the freezing point and achieving a supercooled state, significantly extending the supercooling time window and providing conditions for subsequent controllable crystallization. Capacitive deionization gradually removes ions, breaking the supercooled state and triggering instantaneous condensation of the water, enabling rapid and uniform ice nucleation. Temperature-concentration coordinated control regulates the cooling rate and ion concentration changes in real time, ensuring the entire ice-making process is under optimal control. Optimized design of the cooling integration module and ice-making water circuit system makes water circulation cooling more efficient and energy consumption lower. These technical features work together to achieve the technical effects of improving ice-making efficiency, enhancing ice quality, reducing energy consumption, ensuring food safety, and significantly reducing the freezing failure rate.
