Description

Technical Field

[0001] This application relates to the field of smart home technology, and in particular to an ice-making system and its control method, ice-making equipment, and storage medium. Background Technology

[0002] With the increasing popularity of household ice-making equipment (such as refrigerators and ice makers), automatic ice-making systems have become a core feature of mid-to-high-end models. These systems can automatically complete the processes of water injection, freezing, and de-icing, providing users with convenient ice. Currently, traditional systems generally use room-temperature tap water for ice making. This is because it requires no additional processing devices, has a simple structure, and is low in cost, making it the mainstream choice. However, in practical applications, there are many technical defects that affect ice-making performance and user experience.

[0003] The main drawbacks of traditional tap water ice-making systems include: firstly, low ice-making efficiency, requiring a large amount of electricity to cool tap water from 15-25℃ to below 0℃; secondly, poor ice quality, with impurities in the water easily causing bubbles and turbidity, resulting in a poor taste; thirdly, short system lifespan, as calcium and magnesium ions easily form scale in the evaporator, reducing cooling efficiency; fourthly, high energy consumption, requiring frequent compressor starts and stops, and issues such as premature freezing at excessively low water temperatures and delayed start-up at excessively high temperatures; and fifthly, health risks, as some tap water contains residual chlorine and heavy metals, which directly affect drinking safety when used for ice making.

[0004] Existing solutions such as RO pure water, filtered water, and chilled water ice making can partially improve the problem, but they have significant limitations: RO pure water requires complex water treatment modules, resulting in high costs and maintenance expenses; filtered water has limited impurity removal and increases system complexity; chilled water requires an additional pre-cooling system, increasing energy consumption and the risk of failure. Existing solutions cannot fundamentally solve these problems, and there is an urgent need for low-cost, simple, efficient, and safe technical solutions to address these deficiencies. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing solutions such as RO pure water, filtered water, and chilled water ice making, while they partially improve the situation, they have significant limitations: RO pure water requires complex water treatment modules, resulting in high costs and maintenance expenses; filtered water has limited impurity removal and increases system complexity; chilled water requires an additional pre-cooling system, increasing energy consumption and the risk of failure. Existing solutions cannot fundamentally solve these deficiencies, and there is an urgent need for a low-cost, simple, efficient, and safe technical solution to overcome these shortcomings. This application provides an ice-making system and its control method, ice-making equipment, storage medium, and computer program product. The specific technical solution is as follows: In a first aspect, this application provides an ice-making system for use in ice-making equipment, the ice-making system comprising: a compressor, a condenser, a capillary tube, an evaporator, a refrigerant flow path switching valve, a raw water heating container, a cooked water storage container, and an exhaust pipe; The first end of the compressor is connected to the first end of the refrigerant flow path switching valve, the second end of the refrigerant flow path switching valve is connected to the first end of the condenser, and the third end of the refrigerant flow path switching valve is connected to the first end of the condenser through the exhaust pipe. The second end of the condenser is connected to the first end of the capillary tube, the second end of the capillary tube is connected to the first end of the evaporator, and the second end of the evaporator is connected to the second end of the compressor. The exhaust pipe passes through the interior of the raw water heating container. The inlet of the raw water heating container is connected to a raw water source, the outlet of the raw water heating container is connected to the inlet of the cooked water storage container, and the outlet of the cooked water storage container is connected to an ice-making container.

[0006] In an alternative implementation, the vent pipe also passes through the interior of the boiled water storage container.

[0007] In an optional embodiment, the ice-making system further includes an electric heating element disposed inside the raw water heating container.

[0008] In an alternative embodiment, the ice-making system further includes an evaporator circuit that passes through the interior of the boiled water storage container to allow heat exchange between the evaporator and the boiled water storage container.

[0009] In one optional embodiment, the volume of the raw water heating container is the same as the volume of the cooked water storage container.

[0010] Secondly, this application provides a control method for an ice-making system, applied to any of the ice-making systems described in the first aspect above, the method comprising: Obtain the rated volume of the ice-making container and the current water volume in the boiled water storage container; When the current water storage volume is greater than or equal to the rated volume, the ambient temperature and the temperature of the boiled water in the boiled water storage container are obtained. Based on the ambient temperature and the temperature of the boiled water, the refrigerant flow path switching valve is controlled so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the boiled water in the boiled water storage container for heating.

[0011] In an optional embodiment, controlling the refrigerant flow path switching valve according to the ambient temperature and the boiled water temperature, so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the boiled water in the boiled water storage container for heating, includes: When the ambient temperature is lower than the ambient temperature threshold, the temperature of the boiled water is compared with the ice-making start-up temperature. When the temperature of the boiled water is lower than the ice-making start-up temperature, the refrigerant flow path switching valve is controlled so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the boiled water in the boiled water storage container for heating.

[0012] In an optional implementation, the method further includes: If the current water storage volume is less than the rated volume, control the raw water source to replenish raw water to the raw water heating container; Control the refrigerant flow path switching valve so that the refrigerant flows through the exhaust pipe and transfers the heat of the refrigerant to the raw water in the raw water heating container for preheating; When the raw water in the raw water heating container is preheated to the set temperature, the electric heating element is turned on to heat the raw water in the raw water heating container into cooked water.

[0013] In an optional embodiment, before controlling the refrigerant flow path switching valve to transfer heat from the refrigerant to the raw water in the raw water heating container for preheating, the method further includes: When ice-making demand is received, and rapid ice-making is not required, the control refrigerant flow path switching valve is executed to allow the refrigerant to flow through the exhaust pipe and transfer the heat of the refrigerant to the raw water in the raw water heating container for preheating.

[0014] In an optional implementation, the method further includes: When rapid ice making is required, control the refrigerant flow path switching valve so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the raw water in the raw water heating container for preheating. At the same time, turn on the electric heating element to heat the raw water in the raw water heating container into boiled water.

[0015] In an optional implementation, the method further includes: After the boiled water is transferred from the raw water heating container to the boiled water storage container, when rapid ice making is not required, the boiled water in the boiled water storage container is cooled by natural cooling. When rapid ice making is required, the evaporator circuit is used to transfer the cooling capacity of the evaporator to the boiled water in the boiled water storage container for cooling. When the temperature of the boiled water in the boiled water storage container drops to the preset temperature range, the evaporator circuit is stopped from transferring the cooling capacity of the evaporator to the boiled water in the boiled water storage container for further cooling.

[0016] In an optional implementation, the method further includes: When the evaporator is detected to meet the defrosting conditions, the refrigerant flow path switching valve is controlled so that the refrigerant flows through the exhaust pipe to heat the boiled water in the boiled water storage container. The heat from the boiled water is transferred to the evaporator through the evaporator circuit to assist defrosting, and the cooling energy from the defrosting process is transferred to the boiled water in the boiled water storage container to cool it down.

[0017] Thirdly, an ice-making device is also provided, including a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other through the communication bus. Memory, used to store computer programs; The processor, when executing a program stored in memory, implements the control method of any of the ice-making systems described in the second aspect above.

[0018] Fourthly, a storage medium is also provided, wherein the storage medium stores instructions that, when executed on a computer, cause the computer to perform the control method of any of the ice-making systems described in the second aspect above.

[0019] Fifthly, a computer program product containing instructions is also provided, which, when run on a computer, causes the computer to execute the control method of any of the ice-making systems described above.

[0020] Compared with the prior art, the above-mentioned technical solution provided in this application has the following advantages: The ice-making system flexibly controls the refrigerant flow path through the refrigerant flow path switching valve. Combined with the exhaust pipe passing through the raw water heating container, the waste heat of the compressor exhaust can be used to heat the raw water. This can remove impurities such as dissolved oxygen, microorganisms and residual chlorine from the raw water, improve the transparency and drinking safety of the ice cubes (i.e., solve the problem of poor ice quality and health hazards), and recover and utilize the originally wasted heat energy, reducing the energy consumption of subsequent cooling and ice making of boiled water and the frequency of compressor start-stop (i.e., solve the problem of high energy consumption). At the same time, the boiled water treated by heating can reduce the deposition of calcium and magnesium ions on the surface of the evaporator, extend the system life (i.e., solve the problem of short system life), and does not require additional complex water treatment modules. Functional improvement is achieved only through waste heat utilization and flow path optimization, simplifying the system structure and reducing costs (i.e., overcoming the defects of high cost and complex system in the existing solution), and improving the overall ice-making efficiency and equipment economy.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0027] like Figure 1 The diagram shown is a structural schematic of an ice-making system provided in an embodiment of this application. It is applied to ice-making equipment. The ice-making system 10 includes: a compressor 11, a condenser 12, a capillary tube 13, an evaporator 14, a refrigerant flow path switching valve 15, a raw water heating container 16, a boiled water storage container 17, and an exhaust pipe 18. The compressor 11 is connected to the first end of the refrigerant flow path switching valve 15, the second end of the refrigerant flow path switching valve 15 is connected to the first end of the condenser 12, and the third end of the refrigerant flow path switching valve 15 is connected to the first end of the condenser 12 through the exhaust pipe 18. The second end of the condenser 12 is connected to the first end of the capillary tube 13, the second end of the capillary tube 13 is connected to the first end of the evaporator 14, and the second end of the evaporator 14 is connected to the second end of the compressor 11. The exhaust pipe 18 passes through the inside of the raw water heating container 16. The inlet of the raw water heating container 16 is connected to the raw water source, the outlet of the raw water heating container 16 is connected to the inlet of the cooked water storage container 17, and the outlet of the cooked water storage container 17 is connected to the ice-making container.

[0028] It should be noted that the exhaust pipe 18 can also pass through the inside of the raw water heating container 16 and then through the inside of the cooked water storage container 17 to connect to the first end of the condenser 12.

[0029] By adding an exhaust pipe 18 between the compressor 11 and the condenser 12, and connecting the exhaust pipe 18 to the condenser 12 via the raw water heating container 16 and the cooked water storage container 17, and by introducing a refrigerant flow path switching valve 15 (such as a two-position three-way solenoid valve), the high-temperature and high-pressure refrigerant can flow through the raw water heating container 16 and the cooked water storage container 17 during the heating stage to preheat the raw water in the raw water heating container 16, thereby replacing the electric heating in the traditional solution. This overcomes the shortcomings of the traditional solution, such as high cost and system complexity, and improves the overall ice-making efficiency and equipment economy.

[0030] In addition, the ice-making system 10 also includes an electric heating element 19, which is disposed inside the raw water heating container 16.

[0031] The ice-making system 10 also includes an evaporator circuit 20, which includes a bypass circuit for the refrigerant at the evaporator inlet and outlet or an additional circuit for heat exchange with the evaporator surface. The evaporator circuit 20 passes through the interior of the boiled water storage container 17 to allow heat exchange between the evaporator 14 and the boiled water storage container 17.

[0032] It should be noted that the volume of the raw water heating container 16 is the same as that of the cooked water storage container 17, so as to serve as an intermediate buffer water storage unit, forming a two-stage structure of "main water storage - secondary ice making".

[0033] The compressor 11 described above serves as the power source for the refrigeration system 10. It compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas. The high-temperature, high-pressure refrigerant can provide a heat source for heating the raw water in the raw water heating container 16 through the exhaust pipe 18, or it can directly enter the condenser for cooling. Furthermore, the compressor 11 may include multiple compressors connected in parallel, variable frequency compressors, or compressors of different displacements to adapt to various ice-making conditions. The embodiments of this application do not limit the size and type of the compressor 11.

[0034] The condenser 12 described above is a heat exchanger used to receive refrigerant from the compressor 11 or the exhaust pipe 18, so as to cool and condense the high-temperature and high-pressure refrigerant gas into a medium-temperature and high-pressure liquid. The embodiments of this application do not limit the size and type of the condenser 12.

[0035] The capillary tube 13 described above is a throttling device used to reduce the pressure and temperature of the refrigerant, so that the refrigerant changes from a medium-temperature, high-pressure liquid to a low-temperature, low-pressure wet vapor, thereby achieving refrigeration throttling. The embodiments of this application do not limit the size and type of the capillary tube 13.

[0036] The aforementioned evaporator 14 is used to absorb heat, causing the low-temperature, low-pressure refrigerant to evaporate into gas, thereby achieving cooling of the freezer or refrigerator compartment, or the ice-making compartment. The evaporator 14 can also provide cooling to the boiled water storage container 17 through the evaporator circuit 20. The size and type of the evaporator 14 are not limited in this embodiment.

[0037] The aforementioned refrigerant flow path switching valve 15 is a control valve used to switch the flow path of the refrigerant, such as opening the path formed by the compressor 11 through the discharge pipe 18, the raw water heating container 16, the cooked water storage container 17, and the condenser 12, and opening the path between the compressor and the condenser 12. For example, the refrigerant flow path switching valve 15 can be a two-position three-way solenoid valve to guide the refrigerant to the condenser 12 or the discharge pipe 18. The embodiments of this application do not limit the size and type of the refrigerant flow path switching valve 15.

[0038] The aforementioned raw water heating container 16 is used to store and heat raw water (i.e., tap water). An exhaust pipe 18 passes through its interior, allowing for preheating using the waste heat from the compressor 11's exhaust. It can also be equipped with an electric heating element 19 for auxiliary heating. The raw water heating container 16 heats the raw water to near boiling point, forming "cooked water," which removes impurities and microorganisms. This application does not limit the size or type of the raw water heating container 16.

[0039] The aforementioned boiled water storage container 17 is used to store heated boiled water and control the temperature and volume of the heated boiled water. Its internal exhaust pipe 18 and evaporator circuit 20 can be used for heat preservation and cooling. The embodiments of this application do not limit the size and type of the boiled water storage container 17.

[0040] The aforementioned exhaust pipe 18 is used to connect the refrigerant flow path switching valve 15 and the condenser 12, and passes through the interior of the raw water heating container 16 and the cooked water storage container 17. The exhaust pipe 18 can carry the high-temperature and high-pressure refrigerant gas output by the compressor 11 for heat transfer. The size and type of the exhaust pipe 18 are not limited in this application embodiment.

[0041] The aforementioned electric heating element 19 is an electric heater (such as a heating wire), which is installed inside the raw water heating container 16 to assist in heating the raw water in order to achieve rapid temperature recovery. The embodiments of this application do not limit the size and type of the electric heating element 19.

[0042] The aforementioned evaporator circuit 20 is used to transfer the cooling capacity of the evaporator 14 to the boiled water inside the boiled water storage container 17, thereby cooling it to a temperature suitable for ice making. At the same time, when the evaporator 14 meets the defrosting conditions, the timing of the raw water heating can be controlled, and the heat energy of the high-temperature boiled water can be used to assist defrosting, reduce defrosting energy consumption, and improve the overall energy efficiency. The embodiments of this application do not limit the size and type of the evaporator circuit 20.

[0043] By flexibly adjusting the refrigerant flow path through a refrigerant flow path switching valve, and combining it with the exhaust pipe passing through the raw water heating container and the cooked water storage container, the waste heat from the compressor exhaust can be used to heat the raw water. This heating process removes impurities such as dissolved oxygen, microorganisms, and residual chlorine from the raw water, improving the transparency and drinking safety of the ice (solving the problems of poor ice quality and health hazards). It also recovers and utilizes the previously wasted heat energy, reducing the energy consumption of subsequent cooling and ice making of cooked water and the frequency of compressor start-stop (solving the problem of high energy consumption). At the same time, the heated cooked water reduces the deposition of calcium and magnesium ions on the evaporator surface, extending the system life (solving the problem of short system life). Furthermore, no additional complex water treatment modules are required; functional improvements are achieved solely through waste heat utilization and flow path optimization, simplifying the system structure and reducing costs (overcoming the shortcomings of high cost and system complexity in existing solutions), thus improving overall ice-making efficiency and equipment economy.

[0044] like Figure 2 The diagram shown is a schematic representation of the implementation flow of a control method for an ice-making system provided in this application. This method, applied to an ice-making system, specifically includes the following steps: S201, obtain the rated volume of the ice-making container and the current water volume in the boiled water storage container.

[0045] In this embodiment, the ice-making container can be an ice-making box, and the rated volume of the ice-making container can be the maximum amount of water required to fill all the ice compartments of the ice-making box at once. The current stored water volume can be the real-time volume of boiled water currently available for ice making in the boiled water storage container. The rated volume of the ice-making container and the current stored water volume in the boiled water storage container are obtained. Specifically, the rated volume of the ice-making container can be read from non-volatile memory (such as the Flash memory built into the microcontroller or an external EEPROM). Simultaneously, the current stored water volume in the boiled water storage container is obtained through a level sensor installed in the boiled water storage container; however, this embodiment does not limit the specific method used.

[0046] For example, the rated volume of the ice-making container is read from the non-volatile memory as Q1, and the current water volume in the boiled water storage container is obtained as Q2.

[0047] S202, when the current water storage volume is greater than or equal to the rated volume, obtain the ambient temperature and the temperature of the boiled water in the boiled water storage container.

[0048] In this embodiment, if the current water storage volume is greater than or equal to the rated volume, it indicates that the current water storage volume is sufficient to meet the water storage requirements for ice making. Therefore, it is necessary to obtain the ambient temperature and the temperature of the boiled water in the boiled water storage container. The ambient temperature can be the air temperature around the ice-making equipment (such as a refrigerator), which can be measured by an ambient temperature sensor installed on the ice-making equipment (such as the door or back of the refrigerator). The ambient temperature can be used to predict the trend of boiled water temperature changes. The temperature of the boiled water in the boiled water storage container can be directly measured by a temperature sensor (such as a PT100 platinum resistance thermometer or an NTC thermistor) installed inside the boiled water storage container. This embodiment does not limit this measurement.

[0049] For example, when the current water storage volume Q2 is greater than the rated volume of the ice-making container Q1, the ambient temperature and the temperature of the boiled water in the boiled water storage container are obtained. When the current water storage volume Q2 is equal to the rated volume of the ice-making container Q1, the ambient temperature and the temperature of the boiled water in the boiled water storage container are obtained.

[0050] S203 controls the refrigerant flow path switching valve according to the ambient temperature and the temperature of the boiled water, so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the boiled water in the boiled water storage container for heating.

[0051] In this embodiment, based on the ambient temperature and the temperature of the boiled water obtained from the above steps, the refrigerant flow path switching valve is controlled so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the boiled water in the boiled water storage container for heating, thereby preventing the water temperature from being too low and affecting the start-up of ice making. The refrigerant can be a refrigerant that easily evaporates at low temperatures and easily liquefies at high temperatures; this embodiment does not limit its application to this.

[0052] Based on the above description of the technical solution provided in the embodiments of this application, the rated volume of the ice-making container and the current water volume in the boiled water storage container are obtained; when the current water volume is greater than or equal to the rated volume, the ambient temperature and the boiled water temperature in the boiled water storage container are obtained; according to the ambient temperature and the boiled water temperature, the refrigerant flow path switching valve is controlled so that the refrigerant flows through the exhaust pipe to conduct the refrigerant heat to the boiled water in the boiled water storage container for heating.

[0053] By combining ambient temperature and boiled water temperature, and controlling the refrigerant flow switching valve, the refrigerant flows through the exhaust pipe, transferring its heat to the boiled water in the storage container to heat it. This solves the current problem of excessively low water temperature and allows for proactive prevention based on ambient temperature, greatly improving the reliability and adaptability of the refrigeration system in cold environments. Simultaneously, by utilizing the waste heat from the compressor exhaust to heat the raw water, it removes dissolved oxygen, microorganisms, and residual chlorine, improving the transparency and drinking safety of ice (solving the problems of poor ice quality and health risks), while also recovering previously wasted heat energy.

[0054] Based on this, such as Figure 3 The diagram shown is a schematic representation of the implementation flow of another control method for an ice-making system provided in this application. This method is applied to an ice-making system and may specifically include the following steps: S301, obtain the rated volume of the ice-making container and the current water volume in the boiled water storage container.

[0055] In this embodiment of the application, this step is similar to step S201 above, and will not be described in detail here.

[0056] S302, when the current water storage volume is greater than or equal to the rated volume, obtain the ambient temperature and the temperature of the boiled water in the boiled water storage container.

[0057] In this embodiment of the application, this step is similar to step S202 above, and will not be described in detail here.

[0058] S303 compares the temperature of boiled water with the ice-making start-up temperature when the ambient temperature is below the ambient temperature threshold.

[0059] In this embodiment, when the ambient temperature is below the ambient temperature threshold, the temperature of the boiled water is compared with the ice-making start-up temperature. The ambient temperature threshold can be a preset critical value (e.g., 15°C), which can be understood as the insulation safety threshold of the boiled water storage container. When the ambient temperature is below the ambient temperature threshold, it indicates that the environment is cold, and the gases in the environment are sufficient to continuously absorb heat through the tank wall of the boiled water storage container, potentially causing the temperature of the boiled water inside the container to drop to a dangerous level. The ice-making start-up temperature can be a preset boiled water temperature safety threshold (e.g., 15°C), which can be understood as the minimum water temperature at which the ice-making function can be safely started. When the temperature is below this, water added to the ice-making box may freeze prematurely the moment it flows through the pipe or comes into contact with the low-temperature ice tray, resulting in blockage of the water injection pipe, overload of the ice-making motor, or failure to make ice.

[0060] In another embodiment of this application, if the ambient temperature is not lower than the ambient temperature threshold, it indicates that the external environment is mild, and the temperature of the boiled water can be heated by the environment or at least will not drop too quickly, thus reducing the likelihood of ice-making failure. Therefore, there is no need to perform the subsequent compensation heating step (i.e., step S304), and it is directly determined that "the water temperature condition is met," entering the ice-making preparation state or executing other processes.

[0061] S304, when the temperature of the boiled water is lower than the ice-making start-up temperature, controls the refrigerant flow path switching valve so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the boiled water in the boiled water storage container for heating.

[0062] In this embodiment, when the temperature of the boiled water is lower than the ice-making start-up temperature, the refrigerant flow path switching valve is controlled so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the boiled water in the boiled water storage container for heating. That is, the high-temperature, high-pressure refrigerant vapor, which should originally flow directly to the condenser, is switched to flow through a parallel pipe (i.e., the exhaust pipe) that passes through the raw water heating container and the boiled water storage container. During this process, the high-temperature, high-pressure refrigerant flows through the pipe wall of the exhaust pipe and exchanges heat with the excessively cold boiled water, directly transferring the waste heat obtained in the compressor to the boiled water, thus achieving compensatory heating without additional energy consumption.

[0063] In another embodiment of this application, if the temperature of the boiled water is not lower than the ice-making start-up temperature, it indicates that even in a low-temperature environment, the current temperature of the boiled water is still within a safe range (e.g., it may be because ice-making has just been completed or it has just been heated). Therefore, there is no need to activate waste heat recovery heating (i.e., the step of controlling the refrigerant flow path switching valve to allow the refrigerant to flow through the exhaust pipe to transfer the refrigerant heat to the boiled water in the boiled water storage container for heating), and the current state is maintained, directly entering the ice-making preparation or waiting state.

[0064] In addition, since the evaporator will frost up during operation in the refrigeration system, a defrosting procedure needs to be initiated. This procedure includes: when the evaporator is detected to meet defrosting conditions, controlling the refrigerant flow path switching valve to allow refrigerant to flow through the exhaust pipe to heat the boiled water in the boiled water storage container; using the evaporator circuit to transfer heat from the boiled water to the evaporator for auxiliary defrosting; and using the evaporator circuit to transfer the cooling energy of the defrosting water generated by the evaporator to the boiled water in the boiled water storage container for cooling.

[0065] The defrosting condition of the evaporator can be defined as the continuous operating time of the evaporator meeting a preset defrosting cycle, such as a preset defrosting cycle of 10 seconds, where the evaporator initiates the defrosting program every 10 seconds. Alternatively, the defrosting condition can be monitored by parameters such as frost thickness or heat exchange efficiency. When a set threshold is reached, it indicates that the evaporator meets the defrosting condition, and the defrosting program will be triggered. This application does not limit this aspect.

[0066] When it is anticipated that the evaporator is about to meet defrosting conditions, the refrigerant flow switching valve can be controlled first to direct the high-temperature refrigerant discharged from the compressor into the exhaust pipe, thereby preheating and storing the boiled water in the boiled water storage container, artificially creating a high-temperature heat source. Subsequently, after the defrosting program officially starts (i.e., the evaporator meets defrosting conditions), the evaporator loop is used as an efficient heat transfer medium to continuously transfer the heat stored in the high-temperature boiled water to the frosted evaporator, achieving assisted defrosting and reducing the energy consumption of traditional electric heating. After the defrosting program is completed, the same evaporator loop is used again to recover the "waste cold" carried by the low-temperature defrosting water generated during the defrosting process and conduct it back to the boiled water storage container to actively cool the boiled water that has completed its assisted defrosting task, allowing it to quickly reach the optimal ice-making temperature. This achieves the cascaded and synergistic utilization of heat and cold energy, greatly improving the overall energy efficiency of the system.

[0067] like Figure 4 The diagram shown is a schematic representation of the implementation flow of a control method for an ice-making system provided in this application. This method, applied to an ice-making system, specifically includes the following steps: S401, obtain the rated volume of the ice-making container and the current water volume in the boiled water storage container.

[0068] In this embodiment of the application, this step is similar to step S201 above, and will not be described in detail here.

[0069] S402, when the current water storage volume is greater than or equal to the rated volume, obtain the ambient temperature and the temperature of the boiled water in the boiled water storage container.

[0070] In this embodiment of the application, this step is similar to step S202 above, and will not be described in detail here.

[0071] S403 controls the refrigerant flow path switching valve according to the ambient temperature and the temperature of the boiled water, so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the boiled water in the boiled water storage container for heating.

[0072] In this embodiment of the application, this step is similar to step S203 above, and will not be described in detail here.

[0073] S404, when the current water storage volume is less than the rated volume, control the raw water source to replenish raw water to the raw water heating container.

[0074] In this embodiment of the application, if the current water storage volume is less than the rated volume, it means that the current water storage volume cannot meet the water storage requirements for ice making. Therefore, it is necessary to increase the current water storage volume to meet the ice making requirements, that is, to control the raw water source to supplement raw water to the raw water heating container.

[0075] For example, when the current water storage volume is Q2, which is less than the rated volume of the ice-making container is Q1, the raw water source is controlled to replenish raw water to the raw water heating container.

[0076] S405 controls the refrigerant flow path switching valve so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the raw water in the raw water heating container for preheating.

[0077] In this embodiment, by controlling the refrigerant flow path switching valve, the high-temperature and high-pressure refrigerant output by the compressor is transferred through the exhaust pipe to preheat the raw water in the raw water heating container.

[0078] It should be noted that before controlling the refrigerant flow path switching valve to allow the refrigerant to flow through the exhaust pipe and transfer its heat to the raw water in the raw water heating container for preheating, the raw water heating method can be selected based on the operating conditions. (Refer to the following for details.) Figure 5 The method shown. (As shown) Figure 5 The diagram shown is a schematic representation of the implementation process of a heating control method provided in this application. The method may specifically include the following steps: S501, Obtain ice-making demand. When rapid ice making is not required, execute the step of controlling the refrigerant flow path switching valve to allow the refrigerant to flow through the exhaust pipe and transfer the heat of the refrigerant to the raw water in the raw water heating container for preheating.

[0079] In this embodiment, when ice-making demand is obtained and rapid ice-making is not required, the refrigerant flow path switching valve is executed to allow the refrigerant to flow through the exhaust pipe and transfer the heat of the refrigerant to the raw water in the raw water heating container for preheating (i.e., step S405). That is, the raw water in the raw water heating container is preheated by the high temperature and high pressure refrigerant output by the compressor. This process does not require the electric heating element to be started, and the raw water is preheated only by the refrigerant preheating.

[0080] S502, when rapid ice making is required, controls the refrigerant flow path switching valve so that the refrigerant flows through the exhaust pipe to transfer the heat of the refrigerant to the raw water in the raw water heating container for preheating, and at the same time turns on the electric heating element to heat the raw water in the raw water heating container into boiled water.

[0081] In this embodiment, when rapid ice making is required, the refrigerant flow path switching valve is controlled so that the refrigerant flows through the exhaust pipe to transfer heat from the refrigerant to the raw water in the raw water heating container for preheating. Simultaneously, the electric heating element is activated to heat the raw water in the raw water heating container into boiled water. That is, when rapid ice making is required, the refrigerant flows through the exhaust pipe to preheat the raw water in the raw water heating container, and in conjunction with the electric heating element, heats the raw water in the raw water heating container into boiled water.

[0082] S406, when the raw water in the raw water heating container is preheated to the set temperature, the electric heating element is turned on to heat the raw water in the raw water heating container into cooked water.

[0083] In this embodiment, after the raw water in the raw water heating container has been preheated to a set temperature based on the heat of the refrigerant, the electric heating element can be turned on to heat the raw water in the raw water heating container into boiled water. The set temperature refers to the preset target temperature of the raw water, used to evaluate the raw water temperature (such as 50°C, 60°C, etc.).

[0084] For example, when the heat from the high-temperature, high-pressure refrigerant output by the compressor preheats the raw water in the raw water heating container to a set temperature, the electric heating element is turned on to heat the raw water in the raw water heating container into cooked water.

[0085] After heating the raw water in the heating container to cooked water, the cooked water can be transferred to a cooked water storage container. After the cooked water is transferred, it can be cooled in the storage container according to operating conditions; details can be found in [reference needed]. Figure 6 The method shown. (As shown) Figure 6 The diagram shown is a schematic representation of the implementation process of a cooling control method provided in this application. The method may specifically include the following steps: S601, obtain ice-making requirements.

[0086] In this application embodiment, ice-making demand is obtained. Ice-making demand can be understood as the efficiency of ice-making (such as fast ice-making or no need for fast ice-making).

[0087] S602, according to the cooling method corresponding to the ice-making requirements, cools the boiled water in the boiled water storage container.

[0088] In this embodiment of the application, the boiled water in the boiled water storage container can be cooled according to the ice-making requirements obtained in the above steps and the cooling method corresponding to the ice-making requirements.

[0089] For cooling methods corresponding to ice-making needs, the following can be used to cool the boiled water in the boiled water storage container: Figure 7 The method shown. (As shown) Figure 7 The diagram shown illustrates the implementation flow of another cooling control method provided in this application. This method may specifically include the following steps: S701, when rapid ice making is not required, uses natural cooling to cool the boiled water in the boiled water storage container.

[0090] In this embodiment of the application, when the ice-making requirement is not to make ice quickly, the boiled water in the boiled water storage container can be cooled by natural cooling.

[0091] S702, when rapid ice making is required, the evaporator circuit is used to transfer the cooling capacity of the evaporator to the boiled water in the boiled water storage container for cooling.

[0092] In this embodiment of the application, when the ice-making requirement is to make ice quickly, the evaporator circuit can be used to transfer the cold energy of the evaporator to the boiled water in the boiled water storage container for cooling.

[0093] S703, when the temperature of the boiled water in the boiled water storage container drops to the preset temperature range, the use of the evaporator circuit to transfer the cooling capacity of the evaporator to the boiled water in the boiled water storage container for cooling is stopped.

[0094] In this embodiment of the application, when the temperature of the boiled water in the boiled water storage container drops to a preset temperature range, the transfer of the evaporator's cooling capacity to the boiled water in the boiled water storage container through the evaporator circuit is stopped to cool it down. The preset temperature range can be understood as the optimal temperature range before the boiled water is made into ice (e.g., 15°C to 20°C).

[0095] Furthermore, the control method of the ice-making system provided in this application embodiment is described with reference to specific examples: like Figure 8 The diagram shown is a schematic representation of the implementation flow of another control method for an ice-making system provided in this application embodiment, which may specifically include: The ice-making system provided in this application embodiment can be a boiled water ice-making system based on heat energy recovery and intelligent temperature control. It can include a compressor, condenser, capillary tube, evaporator, two-position three-way solenoid valve, evaporator circuit, raw water heating tank and boiled water storage tank. The two-position three-way solenoid valve is used to control the switching of refrigerant flow path, the raw water heating tank is used to heat raw water into boiled water, the evaporator circuit cools the boiled water, the raw water heating tank contains heating wire for heating raw water, the boiled water storage tank is used to store and control the temperature and volume of boiled water, and the capillary tube is used to reduce the pressure and temperature of refrigerant.

[0096] In this system, an additional exhaust pipe is connected in parallel between the compressor and the condenser. This exhaust pipe passes through a raw water heating tank and a cooked water storage tank. A two-position three-way solenoid valve allows the high-temperature, high-pressure refrigerant to flow through these tanks during the heating phase, preheating the raw water in the heating tank. This preheating process can replace traditional electric heating and can also be combined with heating from the electric heating wire within the heating tank, achieving energy savings and rapid temperature rise. The raw water heating tank and the cooked water storage tank can be configured as storage units of the same volume, serving as an intermediate buffer water storage unit, forming a two-stage structure of "main water storage – secondary ice making".

[0097] S801 determines whether to add raw water based on the water level in the water storage system.

[0098] In this embodiment of the application, it can be determined whether raw water needs to be added based on whether the current water level of the water storage system can meet the ice-making requirements.

[0099] Specifically, check if the water volume Q2 in the boiled water storage tank meets the water volume Qb required for one ice-making cycle (ice maker volume). If Q2 ≥ Qb, no additional water is needed. The refrigerant flow path switching valve can be controlled based on the ambient temperature and the boiled water temperature in the storage container. This allows the refrigerant to flow through the exhaust pipe, transferring heat to the boiled water in the storage container to prevent excessively low water temperature from affecting ice-making startup. If Q2 < Qb, add raw water to the raw water heating tank for heating.

[0100] S802: When it is necessary to add raw water for heating, control the refrigerant flow path and select the heating mode according to the ice-making requirements.

[0101] In this embodiment, when raw water needs to be added, the raw water is added to the raw water heating tank. The ambient temperature is detected by an ambient temperature sensor. When the ambient temperature is lower than a preset ambient threshold (e.g., 15°C), the relationship between the boiled water temperature and the ice-making start-up temperature is determined. When the boiled water temperature is lower than the ice-making start-up temperature, the two-position three-way solenoid valve is controlled to switch the refrigerant flow path. The refrigerant flows through the compressor and becomes a high-temperature and high-pressure state. The high-temperature and high-pressure refrigerant indirectly heats the raw water through copper pipes. In addition, the heating mode (e.g., rapid heating, preheating followed by rapid heating) can be selected according to the cooling needs to determine whether rapid heating is required.

[0102] S803 produces boiled water by controlling the working state of the heating wire according to the heating mode and water temperature.

[0103] In this embodiment, when rapid ice making is not required, the raw water in the raw water heating tank is preheated through the copper pipe using the refrigerant flow path. The compressor exhaust temperature will not be infinitely high enough to directly boil the raw water (generally, the compressor exhaust pipe temperature will not exceed 80°C). Therefore, when the raw water temperature T1 is greater than a certain set temperature Ta (for example, it can be set to 50°C), the electric heating wire is turned on to continue heating the raw water into cooked water. When rapid ice making is required, the raw water needs to be heated quickly into cooked water. No preheating is required, and the heating wire is immediately turned on to heat the raw water together with the refrigerant flow path.

[0104] It should be noted that after heating raw water into cooked water, the cooked water is transported to the cooked water storage tank. During this heating process, the dissolved oxygen content in the water is greatly reduced, calcium and magnesium ions are partially released (forming scale), microorganisms are inactivated, and the water molecule structure becomes more ordered, which is conducive to the formation of dense and transparent ice crystals. Even if the water temperature drops to room temperature, the soluble gases in the water are significantly reduced compared to before heating.

[0105] S804 controls the temperature and volume of boiled water to meet ice-making requirements.

[0106] In this embodiment, as time increases, the water temperature in the boiled water storage tank will tend towards the ambient temperature. When the ambient temperature is low, the boiled water temperature will also be low. If the water temperature is too low during ice making, ice making may not be able to start. Water that is too cold may freeze directly when injected into the refrigeration system through pipes, clogging the pipes. Therefore, an ice-making start-up temperature Tb (e.g., 15°C) can be set for low-temperature heating to prevent the boiled water temperature from becoming too low. If the boiled water temperature is too low, a two-position three-way solenoid valve is used to control the flow path switching to heat the boiled water in the storage tank. This means that the ambient temperature is used to predict whether the boiled water temperature T2 will drop excessively due to the ambient temperature, preventing the boiled water from freezing before entering the ice-making system. The boiled water temperature T2 in the storage tank is used to determine whether the boiled water temperature has dropped below the ice-making start-up temperature Tb (e.g., 15°C).

[0107] In another embodiment of this application, after the raw water is heated to become cooked water, the cooked water is transported to a cooked water storage tank. The cooling method (i.e., high-temperature cooling) can be selected according to the ice-making requirements: if rapid ice making is not required, natural cooling can be used to cool the high-temperature cooked water; if rapid ice making is required, the evaporator circuit in the cooked water storage tank can be used to transfer the evaporator's cooling capacity to the high-temperature cooked water. The temperature of the cooked water before ice making has a suitable range (assumed to be 15~25℃). When the temperature of the cooked water drops to a certain reasonable range (for example, the temperature of the cooked water drops to 25℃), the evaporator circuit and the transfer of cooling capacity between the high-temperature cooked water are cut off.

[0108] In another embodiment of this application, the timing of boiling water heating can be controlled according to the defrosting cycle. Specifically, when the temperature of boiled water is high after heating raw water to boiling water, the heat energy of the high-temperature boiled water supplied to the ice-making system is not effectively utilized because the boiled water does not require a high temperature. However, the defrosting stage requires heating to provide heat, and the evaporator defrosts based on the heat provided by heating. When the defrosting water temperature is lower than the ambient temperature, the cooling capacity of the defrosting water obtained by the refrigeration system through the consumption of electricity cannot be utilized. Therefore, the boiling water cooling and defrosting process can be combined. Based on the defrosting cycle, the boiled water is heated, and then defrosting begins. The heat of the high-temperature boiled water is transferred to the evaporator through the evaporator circuit in the boiled water storage tank to assist defrosting, thereby improving the heat energy utilization of the ice-making system, increasing energy efficiency, and reducing energy consumption.

[0109] Furthermore, the execution of defrosting on the evaporator can be determined based on whether the evaporator meets the defrosting conditions. Specifically, meeting the defrosting conditions can mean that the evaporator's continuous operating time meets a preset defrosting cycle, such as a preset defrosting cycle of 10 seconds, in which case the evaporator initiates the defrosting program every 10 seconds. Alternatively, the defrosting process can be automatically triggered by monitoring the evaporator's frost status, such as frost thickness or heat exchange efficiency, and when a set threshold is reached. This application does not limit this approach.
