Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to control methods, ice-making equipment and storage media for ice-making equipment. Background Technology

[0002] Currently, ice-making equipment is widely used in various scenarios such as homes, restaurants, and supermarkets, and users' requirements for ice quality are constantly increasing. Among them, the transparency of ice is one of the important indicators for measuring the performance of ice-making equipment and the quality of ice. High-transparency ice not only has a better visual effect, but also reduces the impact of impurities on the taste of beverages, making it especially suitable for scenarios such as cold drink preparation and seafood preservation.

[0003] Currently, ice-making equipment on the market typically uses fixed ice-making control logic, meaning that the heat dissipation components and power components operate according to preset fixed operating parameters to complete the ice-making process.

[0004] However, during the ice-making process, as the water cools down, dissolved substances in the water used by the ice-making equipment gradually precipitate out and adhere to the ice crystals, causing the ice produced by the ice-making equipment to become less transparent. Summary of the Invention

[0005] The main objective of this application is to provide a control method, ice-making equipment, and storage medium for ice-making equipment, aiming to solve the technical problem of low transparency of ice produced by ice-making equipment.

[0006] To achieve the above objectives, this application proposes a control method for an ice-making device. The ice-making device includes a detection component, a heat dissipation component, a power component, and a control device, wherein the detection component, heat dissipation component, and power component are electrically connected to the control device. The method of this application includes: During the ice-making process, the TDS value inside the ice-making equipment is acquired by the detection component; Based on the TDS value, adjust the operating parameters of the heat dissipation component and the power component. The operating parameters of both the heat dissipation component and the power component include the rotation speed. The rotation speed of the heat dissipation component is negatively correlated with the transparency of the ice, while the rotation speed of the power component is positively correlated with the transparency of the ice.

[0007] In addition, to achieve the above objectives, this application also proposes an ice-making device, including: a memory, a processor, and a control program for the ice-making device stored in the memory and executable on the processor, wherein the control program for the ice-making device is configured to implement the steps of the control method for the ice-making device as described above.

[0008] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, storing a control program for an ice-making device. When the control program for the ice-making device is executed by a processor, it implements the steps of the control method for the ice-making device as described above.

[0009] The one or more technical solutions proposed in this application have at least the following technical effects: During the ice-making process, the TDS value inside the ice-making equipment is detected in real time, and the cooling speed is adaptively adjusted based on the TDS value to control the freezing rate, preventing rapid freezing that would cause air bubbles and dissolved substances in the water to be trapped inside the ice, thus improving the density and purity of the ice. By matching and adjusting the stirring speed, the water flow disturbance is enhanced, promoting the escape of dissolved substances and air bubbles from the water, further reducing the content of air bubbles and dissolved substances inside the ice. In this way, through the coordinated cooperation of the heat dissipation component and the power component, a stable improvement in the transparency of the ice is achieved under different water quality conditions.

[0013] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0014] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0015] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0016] With the improvement of living standards, ice-making equipment has been widely used in various scenarios such as homes, restaurants, and supermarkets. Users' requirements for ice quality are also constantly increasing. Among them, the transparency of ice is one of the important indicators for measuring the performance of ice-making equipment and the quality of ice. High transparency ice not only has a better visual effect, but also reduces the impact of impurities on the taste of beverages, and is especially suitable for scenarios such as cold drink preparation and seafood preservation.

[0017] Currently, ice-making equipment on the market typically employs fixed ice-making control logic, meaning that the heat dissipation and power components operate according to preset fixed parameters to complete the ice-making process. However, in actual use, the ice-making environment and operating status of ice-making equipment undergo significant dynamic changes, with TDS value being a key factor affecting ice transparency. Specifically, TDS values ​​vary considerably depending on the usage scenario. During the ice-making process, as water cools and solidifies, dissolved substances in the water gradually precipitate and adhere to the ice crystals, causing the ice to appear white and cloudy, and reducing its transparency. Existing ice-making equipment does not detect or specifically adjust the TDS value, thus failing to prevent the precipitation of dissolved substances from affecting ice transparency.

[0018] To address the aforementioned issues, this application proposes a control method for an ice-making device. The main technical solution includes: during the ice-making process, acquiring the TDS value detected by a detection component within the ice-making device; and adjusting the operating parameters of the heat dissipation component and the power component based on the TDS value. The operating parameters of both the heat dissipation component and the power component include rotational speed. The rotational speed of the heat dissipation component is negatively correlated with the transparency of the ice, while the rotational speed of the power component is positively correlated with the transparency of the ice.

[0019] During the ice-making process, the TDS value within the ice-making equipment is monitored in real time. The cooling speed is adaptively adjusted based on the TDS value to control the freezing rate, preventing rapid freezing that would trap air bubbles and dissolved substances in the water inside the ice, thus improving the density and purity of the ice. By matching and adjusting the stirring speed, water flow disturbance is enhanced, promoting the escape of dissolved substances and air bubbles from the water, further reducing the content of air bubbles and dissolved substances inside the ice. In this way, through the coordinated operation of the cooling and power components, a stable improvement in ice transparency is achieved under different water quality conditions.

[0020] This application provides an ice-making device, and the control method of the ice-making device is applied to the device. The ice-making device includes a detection component, a heat dissipation component, a power component, and a control device. The detection component, heat dissipation component, and power component are electrically connected to the control device. The various components of the ice-making device will be described in detail below.

[0021] The ice-making equipment can be any device capable of making ice, such as an ice maker, a freezer with a built-in ice-making function, or a refrigerator with a built-in ice-making function. This embodiment uses an ice maker as an example, which is used to quickly cool liquid water to form ice cubes for user use. The ice-making equipment can be used as industrial equipment in production operations, or as food processing equipment to produce food ice cubes. It can also be used in medical, cold chain transportation, and other fields; this embodiment does not impose specific limitations in these areas. As an example, the ice-making equipment in this embodiment is a household appliance, configured in offices, kitchens, restaurants, etc., for producing food ice cubes. When used for ice making, the ice-making equipment can be installed inside a refrigerator, freezer, or other similar equipment, or it can be used independently.

[0022] Detection Components: A collection of components in an ice-making device used to collect various ice-making related parameters. Their function is to convert the detected physical quantities into electrical signals and transmit them to the control device, providing data support for parameter adjustment. In this application, specifically, two probe structures are installed on the top cover of the refrigeration equipment to detect the conductivity of water and obtain the TDS value. As an example, this detection component can be installed on the top cover of the refrigeration equipment or in other locations inside the refrigeration equipment; regardless of its location, it can achieve the measurement of water conductivity.

[0023] Heat dissipation component: A component in the refrigeration system of an ice-making device used to dissipate heat. In this application, it is specifically a heat dissipation fan equipped on the condenser. Its function is to control the refrigeration efficiency by adjusting the speed, thereby changing the freezing speed of ice. Its operating status directly affects the transparency of ice and the ice-making efficiency.

[0024] Power component: The component that provides power for water stirring in ice-making equipment. In this application, it is specifically the stirring motor in the top cover assembly, which, together with the rotating shaft and stirring fan blades, realizes water stirring. Its function is to accelerate the diffusion and discharge of gas in the water by stirring, thereby improving the transparency of ice. At the same time, the rotation speed needs to be controlled to avoid introducing new air bubbles or losing cooling capacity.

[0025] Control device: The control unit of the ice-making equipment is responsible for receiving parameter signals from the detection components, parsing the data according to preset logic, and outputting adjustment commands to the heat dissipation components and power components to realize the automated control of the ice-making process.

[0026] The aforementioned refrigeration system may include a compressor, a condenser, and refrigeration components. These components can be connected via refrigerant piping to form an ice-making circuit. The compressor compresses low-pressure gaseous refrigerant into high-temperature, high-pressure gaseous refrigerant. This high-temperature, high-pressure gaseous refrigerant is cooled and liquefied by the condenser to form high-pressure liquid refrigerant. The liquid refrigerant is then transported to the refrigeration components. Inside the components, the liquid refrigerant absorbs heat and transforms from a liquid to a gaseous state to cool the liquid water and make ice. The gaseous refrigerant then passes through the compressor and condenser again to become liquid refrigerant. The liquid refrigerant returns to the refrigeration components to continue evaporating, absorbing heat, and making ice. This process is repeated continuously, achieving continuous cooling to freeze the liquid water into ice.

[0027] The control device described above includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the control method of the ice-making device in the above embodiments.

[0028] The ice-making equipment provided in this application, employing the control method of the ice-making equipment in the above embodiments, can solve the technical problem of low transparency of the ice produced by the ice-making equipment. Compared with the prior art, the beneficial effects of the ice-making equipment provided in this application are the same as the beneficial effects of the control method of the ice-making equipment provided in the above embodiments, and other technical features of the ice-making equipment are the same as those disclosed in the method of the previous embodiment, and will not be repeated here.

[0029] Based on the same inventive concept, this application provides a control method for an ice-making device, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the control method for the ice-making equipment of this application.

[0030] In this embodiment, the control method for the ice-making equipment includes steps S10 to S20: Step S10: During the ice-making process, obtain the TDS value inside the ice-making device detected by the detection component.

[0031] Ice-making process: refers to the complete process from the moment ice-making equipment is filled with ice-making water and the refrigeration system is started to cool down, to the moment the water gradually freezes into ice blocks from bottom to top. During this process, the freezing speed and the state of water stirring directly determine the transparency of the ice blocks, which is the stage in which the parameters of this application are adjusted.

[0032] TDS value: This value can be obtained by measuring the conductivity of water using a probe. TDS (Total Dissolved Solids) is a quantitative indicator; a higher TDS value indicates a higher concentration of dissolved substances in the water, and vice versa. In this article, the unit for TDS is ppm, which represents 1 milligram of dissolved substances per liter of water. These dissolved substances can include minerals, salts, metals, organic matter, etc.

[0033] In one optional approach, after the ice-making equipment starts and enters the ice-making process, the control device sends detection commands to two probes on the top cover of the ice-making equipment. The probes contact the ice-making water in the inner tank and detect the water's conductivity. The conductivity analog signal is transmitted to the microprocessor on the main board. The microprocessor converts the conductivity data into a specific TDS value. The system can be set to perform this detection and conversion at regular intervals, updating and storing the TDS value in real time to ensure the data accurately reflects water quality changes during the ice-making process. Specifically, a mapping or conversion relationship between conductivity data and TDS value can be set, and the conductivity data can be converted into a TDS value based on this mapping or conversion relationship.

[0034] In another optional method, during the ice-making process, the probe on the top cover is continuously working, without the need for active command from the control device. It continuously collects the conductivity signal of the ice-making water in the inner tank, filters the collected signal to remove instantaneous abnormal signals caused by water stirring and temperature changes, and transmits the processed effective conductivity signal to the microprocessor of the control device in real time. The microprocessor directly calls the preset conversion table to quickly match the corresponding TDS value, providing data for subsequent adjustment.

[0035] Understandably, by accurately obtaining the TDS value during the ice-making process through the detection component, input conditions are provided for the control device to determine the adjustment strategy of the heat dissipation component and the power component.

[0036] Step S20: Adjust the operating parameter values ​​of the heat dissipation component and the power component according to the TDS value. The operating parameters of both the heat dissipation component and the power component include the rotation speed. The rotation speed of the heat dissipation component is negatively correlated with the transparency of the ice, and the rotation speed of the power component is positively correlated with the transparency of the ice.

[0037] Operating parameter values: These refer to the working parameters of the heat dissipation component and the power component during operation. They are specific quantitative indicators used by the control device to adjust the operating state of the components. Both the heat dissipation component and the power component can include rotational speed in their operating parameters. If the heat dissipation component is a cooling fan and the power component is a stirring motor, the operating parameter value of the heat dissipation component can be the rotational speed of the cooling fan, and the operating parameter value of the power component can be the rotational speed of the stirring motor. The rotational speed of the cooling fan is characterized by its duty cycle, while the rotational speed of the stirring motor is characterized by its revolutions per minute. Furthermore, in addition to rotational speed, the operating parameters of the power component can also include switching time.

[0038] Ice transparency: refers to the ability of ice to transmit light. It is an indicator of the quality of ice made by transparent ice making machines. The higher the transparency, the less air and impurities are trapped inside the ice. Its level is determined by factors such as TDS value, freezing speed, and water stirring effect.

[0039] It should be noted that the TDS value is negatively correlated with the transparency of ice; that is, the lower the TDS value, the more transparent the ice, and the higher the TDS value, the less transparent the ice. This is the input condition for the entire control logic of this application. Dissolved particles are natural nucleation points for water. When the water temperature drops too quickly, they tend to freeze inside the water body rather than freezing layer by layer from bottom to top. This traps gas in the middle, resulting in opaque ice. The rotation speed of the heat dissipation component is negatively correlated with the transparency of the ice, meaning that the higher the rotation speed of the heat dissipation component, the less transparent the ice produced. The rotation speed of the power component is positively correlated with the transparency of the ice, meaning that the higher the rotation speed of the power component, the more transparent the ice produced.

[0040] During the ice-making process, the slower the freezing speed, the more transparent the ice. Specifically, the freezing speed can be controlled using a heat dissipation component. The higher the rotation speed of the heat dissipation component, the better the ice-making effect and the faster the freezing speed, but the transparency of the ice will decrease. The principle is that during the freezing process, water molecules arrange themselves into hexagonal crystals, expelling gases from the water. If the freezing speed is greater than the diffusion speed of the gases in the water, insufficient gas expulsion will occur, resulting in opaque ice with trapped gases. Therefore, to improve the transparency of the ice, the rotation speed of the heat dissipation component needs to be adjusted.

[0041] Within a certain range, the faster the rotation speed of the power unit, the more transparent the ice. Specifically, rapid stirring accelerates gas diffusion and degassing, making the ice transparent. However, faster rotation speeds also accelerate the dissipation of cold energy into the air, and the heat generated by the power unit affects ice-making efficiency, as well as increasing noise levels. High efficiency can only be achieved within a certain timeframe. Furthermore, stirring speeds exceeding a certain range can cause water turbulence, introducing new gases into the water. Tests show that the maximum rotation speed should be controlled below 200 rpm. Therefore, to improve the transparency of the ice, the rotation speed of the power unit needs to be adjusted.

[0042] In one optional approach, the control device internally presets a correspondence table between TDS values ​​and the duty cycle of the cooling fan and the speed of the stirring motor. For example, when the TDS value is less than or equal to 150, the cooling fan duty cycle is 50% and the stirring motor speed is 120 rpm; when the TDS value is greater than 150, the cooling fan duty cycle is 30% and the stirring motor speed is 150 rpm. After obtaining the TDS value, the control device directly consults the correspondence table to determine the target speeds of the cooling component and the power component, and sends speed adjustment commands to the cooling fan and the stirring motor respectively. The cooling fan changes its actual speed by adjusting its duty cycle, and the stirring motor directly adjusts to the target rpm value. After adjustment, it maintains stable operation at that speed.

[0043] In another optional approach, the control device establishes an algorithmic model relating TDS value to speed adjustment. The model is based on the logic that higher TDS values ​​require lower cooling fan speeds (to reduce icing) and higher agitation speeds (to accelerate exhaust). For example, it might be set that for every 100 increase in TDS value, the cooling fan duty cycle decreases by 10% and the agitator motor speed increases by 20 rpm, with an initial reference speed of 50% cooling fan duty cycle and 120 rpm agitator motor speed. The control device inputs the acquired actual TDS value into the model to calculate the target speeds for the cooling and power components, sends adjustment commands to both components, and simultaneously receives real-time speed feedback signals from the components. If the actual speed deviates from the target speed by more than 5 rpm or 5% of the duty cycle, a fine-tuning command is immediately sent to achieve precise closed-loop regulation.

[0044] Understandably, by linking the TDS value to the rotation speed of the two components, and utilizing the negative correlation between the heat dissipation rotation speed and ice transparency (the higher the rotation speed, the faster the freezing, the less gas is expelled, and the lower the ice transparency), and the positive correlation between the power rotation speed and ice transparency (within a reasonable range, the higher the rotation speed, the more thorough the stirring, the more complete the gas expulsion, and the higher the ice transparency), targeted rotation speed adjustment under different TDS values ​​can be achieved. This solves the problem of uneven ice transparency at fixed rotation speeds and is a step towards achieving high-transparency ice making.

[0045] In this embodiment, during the ice-making process, the TDS value within the ice-making equipment is monitored in real time. The cooling rotation speed is adaptively adjusted based on the TDS value to control the freezing rate, preventing rapid freezing that would trap air bubbles and dissolved substances in the water inside the ice, thus improving the density and purity of the ice. By adjusting the stirring speed accordingly, water flow disturbance is enhanced, promoting the escape of dissolved substances and air bubbles from the water, further reducing the content of air bubbles and dissolved substances inside the ice. Thus, through the coordinated operation of the cooling and power components, a stable improvement in ice transparency is achieved under different water quality conditions.

[0046] According to the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 The control methods for ice-making equipment include: Step S10: During the ice-making process, acquire the TDS value inside the ice-making device detected by the detection component; Step S30: Obtain the cumulative ice-making time of the ice-making equipment; Cumulative ice-making time: This refers to the continuous ice-making time from the start of ice-making equipment to the current moment, measured in hours / minutes. It is recorded in real time by a timer within the control device and serves to reflect the stage characteristics of the ice-making process. In this application, the ice is relatively thin in the early stages of ice-making, resulting in high thermal conductivity. In the later stages, the ice becomes thicker, leading to a decrease in thermal conductivity. Furthermore, as the ice-making time increases, dissolved solids in the water are more likely to precipitate, causing changes in the TDS value. This is an important auxiliary parameter affecting ice transparency and ice-making efficiency, in addition to the TDS value.

[0047] In one alternative approach, the microprocessor of the control device integrates a timing module. When the ice-making equipment starts making ice and detects that the water temperature has reached the freezing condition, the timing module automatically starts, records the continuous ice-making time in real time, and stores the accumulated ice-making time data in the storage unit of the control device. When the control device needs this data, it reads it directly from the storage unit.

[0048] In another optional approach, the control device of the ice-making equipment is linked with the stirring motor. The timing starts when the stirring motor starts and enters the working speed corresponding to ice making. The cumulative ice-making time is calculated by detecting the actual running time of the stirring motor. The control device collects the running status signal of the stirring motor in real time, eliminates non-ice-making running time such as pauses and malfunctions, and adds up the effective running time to the cumulative ice-making time, which is then transmitted to the microprocessor in real time for subsequent adjustment.

[0049] Understandably, since the thermal conductivity and water quality changes vary at different stages of ice making, adjusting the speed solely based on the TDS value cannot meet the needs of the entire ice making process. After obtaining the cumulative ice making time, it can be combined with the TDS value to form a dual adjustment basis, making the speed adjustment more in line with the actual characteristics of the ice making process and further improving the stability of ice transparency.

[0050] It should be noted that the cumulative ice-making time in step S30 and the TDS value in step S10 can be obtained simultaneously.

[0051] Step S40: Adjust the operating parameter values ​​of the heat dissipation component and the power component according to the TDS value and the cumulative ice-making time.

[0052] In one optional approach, the control device internally presets a table mapping multiple TDS value ranges to cumulative ice-making time ranges. Each range is matched with a unique cooling fan duty cycle and stirring motor speed. For example, when TDS ≤ 150, 0–2 hours correspond to a cooling fan duty cycle of 50% and a stirring motor speed of 120 rpm; 2–4 hours correspond to a cooling fan duty cycle of 70% and a stirring motor speed of 60 rpm. When TDS > 150, 4–7 hours correspond to a cooling fan duty cycle of 90% and a stirring motor speed of 0 rpm. After simultaneously acquiring the TDS value and cumulative ice-making time, the control device determines the range combination to which they belong, looks up the target speed in the table, sends adjustment commands to both components, and maintains operation.

[0053] In another optional approach, the control device internally establishes an algorithm model relating TDS value, cumulative ice-making time, and the rotational speeds of the two components. The model assigns different adjustment weights to TDS value and cumulative ice-making time, with TDS value accounting for 60% and cumulative ice-making time for 40%. It also establishes an adjustment logic where a longer cumulative ice-making time results in a higher cooling rotational speed and a lower power rotational speed. The control device substitutes the actual TDS value and cumulative ice-making time into the model to calculate the target rotational speeds of the cooling and power components. After sending adjustment commands, it monitors the changes in both parameters in real time. If either parameter is updated, it immediately recalculates and fine-tunes the rotational speeds, achieving dynamic adjustment.

[0054] In this embodiment, based on the adjustment of a single TDS value, a comprehensive adjustment is made in combination with the cumulative ice-making time, which makes up for the limitations of single parameter adjustment. It solves the problems of abnormal freezing speed caused by ice thickening and reduced thermal conductivity in the later stage of ice making, as well as the TDS value change caused by solid solution precipitation. This makes the speed adjustment of the two components adapt to the entire ice-making process, ensuring high transparency in the early stage of ice making, while maintaining ice quality and ice-making efficiency in the later stage of ice making.

[0055] Based on the above embodiments of this application, in the third embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 The control methods for ice-making equipment include: Step S10: During the ice-making process, acquire the TDS value inside the ice-making device detected by the detection component; Step S50: Obtain the cumulative ice-making time of the ice-making equipment and the water temperature in the ice-making equipment; In one alternative approach, the water temperature can be detected by an NTC temperature sensor installed in the inner tank. The sensor is in direct contact with the water and collects analog water temperature signals in real time. These signals are then transmitted to the microprocessor of the control device. The microprocessor converts the analog signals into specific Celsius values ​​and performs a detection and data update at regular intervals to ensure the real-time nature of the water temperature data.

[0056] In another alternative approach, water temperature is detected by a temperature sensor array. Multiple NTC temperature sensors are placed at different heights in the tank to collect water temperature data from different locations simultaneously. The control device calculates the average value of multiple data points, eliminates abnormal water temperature values ​​caused by localized cooling, and obtains an accurate average water temperature, providing a reliable basis for judgment during the ice-making stage.

[0057] Understandably, water temperature serves as a criterion for determining the freezing stage, distinguishing between the cooling and freezing stages of the water body. This avoids unnecessary fine-tuning during the cooling stage, saving energy. The cumulative ice-making time, combined with water temperature, is timed only during the freezing stage, making the time data more consistent with the actual ice-making process. Together with the TDS value, this forms a triple adjustment basis, further improving the accuracy and targeting of speed adjustment.

[0058] If the water temperature is lower than the preset water temperature, step S40 is executed to adjust the operating parameter values ​​of the heat dissipation component and the power component according to the TDS value and the cumulative ice-making time.

[0059] Water temperature refers to the temperature of the water used for ice making in the inner tank of the ice-making equipment, expressed in degrees Celsius (°C). In this embodiment, it can be detected and obtained by an NTC temperature sensor. Its function is to reflect the freezing state of the water. When the water temperature is higher than the freezing threshold, the water is only in the cooling stage and has not started to freeze. When the water temperature is lower than the freezing threshold, the water enters the actual freezing stage.

[0060] Preset water temperature: refers to the preset critical temperature threshold for water freezing inside the control device. For example, in this embodiment, it is specifically set to 2°C. Its function is to serve as a criterion for judging the ice-making stage. When the water temperature is higher than this value, there is no need to make fine speed adjustments. It is only necessary to cool down at full speed to increase the cooling rate. When the water temperature is lower than this value, the water enters the freezing stage. The speed needs to be adjusted in combination with the TDS value and the cumulative ice-making time to ensure the transparency of the ice.

[0061] In one optional approach, the control device has a preset water temperature and stores a table corresponding to the rotation speed of the TDS value and the cumulative ice-making time range. When the control device detects that the water temperature is the preset water temperature, it determines that the water has entered the freezing stage, retrieves the real-time TDS value and cumulative ice-making time data, determines the range combination to which the two belong, for example, TDS value ≤ 150 and cumulative ice-making time is 0~2 hours, looks up the corresponding table to obtain the cooling fan duty cycle of 50% and the stirring motor speed of 120 rpm, sends adjustment commands to the two components, and continuously monitors the water temperature.

[0062] In this embodiment, when the water temperature is lower than the preset water temperature, the water enters the freezing stage. This is the key stage that determines the transparency of the ice. By combining the TDS value and the cumulative ice-making time for fine-tuning the rotation speed, the freezing speed and stirring effect can be effectively controlled, avoiding insufficient gas expulsion caused by freezing too quickly, and adapting to the heat conduction characteristics of different stages of ice making.

[0063] For any of the above embodiments, adjusting the operating parameter values ​​of the heat dissipation component and the power component based on the TDS value and the cumulative ice-making time includes: obtaining preset values ​​associated with the TDS value and the cumulative ice-making time, wherein the preset values ​​include preset operating parameter values ​​for the heat dissipation component and the power component; adjusting the current operating parameter value of the heat dissipation component to the preset operating parameter value of the heat dissipation component, and adjusting the current operating parameter value of the power component to the preset operating parameter value of the power component. A mapping table can be pre-constructed, showing different TDS values, different cumulative ice-making times, and the preset operating parameter values ​​of the heat dissipation component and the power component across four dimensions. In practical applications, the preset operating parameter values ​​of the heat dissipation component and the power component can be obtained by looking up this mapping table using the obtained TDS value and the cumulative ice-making time.

[0064] For any of the above embodiments, there are two specific ways to adjust the operating parameter values ​​of the heat dissipation component and the power component based on the TDS value and the cumulative ice-making time. Each specific implementation method will be described in detail below.

[0065] The first feasible implementation method: Adjusting the operating parameter values ​​of the heat dissipation component and the power component according to the TDS value and the cumulative ice-making time includes the following steps S41 to S44: Step S41: Determine the first TDS value interval to which the TDS value belongs; The first TDS value range refers to the preset TDS value range within the control device based on the degree of influence of TDS value on the transparency of ice. Its purpose is to provide a classification basis for matching a specific ice-making time range. The range division is based on experimental data, for example, it is divided into three ranges: TDS value ≤ 150, 150 < TDS value ≤ 400, and TDS value > 400. Different ranges correspond to different impurity contents, so the corresponding ice-making time range divisions are also different.

[0066] In one optional approach, the control device internally presets three first TDS value ranges: TDS value ≤ 150, 150 < TDS value ≤ 400, and TDS value > 400. Each range has a defined numerical threshold. After the control device obtains the real-time TDS value, it compares the value with the threshold of the two ranges one by one. For example, if a TDS value of 200 is detected, it is determined that it belongs to the first TDS value range of 150 < TDS value ≤ 400. The determination result is stored in the microprocessor to provide a basis for subsequent steps.

[0067] In another optional approach, the control device internally presets a judgment algorithm for a first TDS value range. The algorithm sets judgment conditions based on the logic that higher TDS values ​​have a greater impact on ice transparency. For example, it sets the following criteria: if the detected TDS value is ≤150, it belongs to the first range, representing a low-hardness range; if 150 < TDS value ≤400, it belongs to the second range, representing a medium-hardness range; and if the TDS value >400, it belongs to the third range, representing a high-hardness range. The control device substitutes the detected actual TDS value into the algorithm, determines its first TDS value range through logical judgment, and marks the range characteristics to facilitate the retrieval of the corresponding ice-making time range.

[0068] Understandably, by dividing TDS values ​​into different ranges, a specific ice-making time range can be matched according to the characteristics of water with different hardness, avoiding the problem of poor adaptability of ice-making time ranges caused by large TDS value ranges. This provides a clear classification guide for determining the first ice-making time range and ensures the targeted nature of the adjustment logic.

[0069] Step S42: Determine the first ice-making time interval to which the cumulative ice-making time belongs under the first TDS value interval. Each TDS value interval corresponds to at least one ice-making time interval, and the ice-making time intervals corresponding to different TDS value intervals are different from each other. First ice-making time interval: This refers to a separately preset cumulative ice-making time interval under each first TDS value interval. Its function is to work with the first TDS value interval to form a unique adjustment combination. The first ice-making time intervals under each first TDS value interval are different. For example, when the TDS value is ≤150, it corresponds to 0~2 hours, 2~4 hours, and 4~7 hours. When the TDS value is >150, it corresponds to 0~2.5 hours, 2.5~5 hours, and 5~9 hours. The basis for this setting is that the rate of precipitation of solids in water and the rate of change of the thermal conductivity of ice are different under different TDS values.

[0070] In one optional approach, the control device internally presets a corresponding first ice-making time interval for each first TDS value interval. For example, a TDS value ≤ 150 corresponds to 0~2 hours, 2~4 hours, and 4~7 hours, while a TDS value ≤ 400 corresponds to 0~2.5 hours, 2.5~5 hours, and 5~9 hours. After determining that the TDS value belongs to TDS value ≤ 150, the control device retrieves the three sets of first ice-making time intervals corresponding to that interval, compares the real-time cumulative ice-making time (e.g., 1.5 hours) with the interval threshold, and determines that it belongs to the first ice-making time interval of 0~2 hours.

[0071] In another optional approach, the control device internally presets dynamic correspondence rules for the first ice-making time interval for each first TDS value interval. For example, in the low hardness interval, there are fewer impurities and the ice-making time interval spans a large range, so it can be set to be an interval of 2-3 hours; in the medium hardness interval, there are more impurities and the solid solution precipitates quickly, so the ice-making time interval spans a small range, so it can be set to be an interval of 2.5 hours. After determining the interval to which the TDS value belongs, the control device generates the corresponding first ice-making time interval in real time according to the correspondence rules of that interval, and then substitutes the cumulative ice-making time into it to determine the specific interval to which it belongs, making the time interval more closely match the characteristics of the TDS value.

[0072] Understandably, since the rate of change of impurities and thermal conductivity during the ice-making process varies under different TDS values, matching a dedicated first ice-making time range to each first TDS value range can avoid adjustment deviations caused by using the same time range under different TDS values. This makes the combination of TDS value and cumulative ice-making time more accurate, providing a unique matching basis for obtaining the first preset value in the future.

[0073] Step S43: Obtain a first preset value associated with the first ice-making time interval, wherein the first preset value includes a first operating parameter value of the heat dissipation component and a second operating parameter value of the power component; First preset value: refers to the target values ​​of the operating parameters of the heat dissipation component and the power component associated with each first ice-making time interval. Its function is to provide clear quantitative indicators for speed adjustment, including the first operating parameter value of the heat dissipation component and the second operating parameter value of the power component. Each first ice-making time interval corresponds to a fixed set of first preset values.

[0074] In one optional approach, the control device has a pre-set associated database that stores a one-to-one correspondence between each first ice-making time interval and a first preset value under each first TDS value interval. For example, the low hardness interval of 0-2 hours corresponds to a first operating parameter value (heat dissipation duty cycle) of 50% and a second operating parameter value (stirring motor speed) of 120 rpm. After determining the specific first ice-making time interval, the control device accurately queries the database based on the determined first TDS value interval and first ice-making time interval to obtain the corresponding first preset value and extracts the two operating parameter values ​​for subsequent adjustment.

[0075] Understandably, combining the TDS value and the cumulative ice-making time range into quantifiable target values ​​for component operating parameters avoids blindness in the adjustment process. At the same time, by using preset correlation or model calculation, the first preset value can be quickly obtained, reducing the real-time calculation pressure on the control device, improving the response speed of speed adjustment, and providing a clear basis for subsequent precise adjustment.

[0076] Step S44: Adjust the current operating parameter value of the heat dissipation component to the first operating parameter value, and adjust the current operating parameter value of the power component to the second operating parameter value; wherein, the cumulative ice-making time is positively correlated with the first operating parameter value and negatively correlated with the second operating parameter value.

[0077] First operating parameter value: refers to the target operating parameter value of the heat dissipation component in the first preset value. In this application, it is specifically the target duty cycle of the heat dissipation fan. Its function is to clarify the specific operating state of the heat dissipation component under the corresponding TDS value and ice-making time during the icing stage. This value is positively correlated with the cumulative ice-making time.

[0078] The second operating parameter value refers to the target operating parameter value of the power component in the first preset value. In this application, it is specifically the target speed of the stirring motor. Its function is to clarify the specific operating state of the power component under the corresponding TDS value and ice-making time during the freezing stage. This value is negatively correlated with the cumulative ice-making time.

[0079] In one optional approach, after the control device obtains the first operating parameter value and the second operating parameter value, it simultaneously sends a speed adjustment command to the heat dissipation component and the power component. The cooling fan adjusts the power supply duty cycle according to the first operating parameter value, gradually adjusting the current speed to the operating state corresponding to the target duty cycle. The stirring motor directly adjusts to the target speed according to the second operating parameter value. During the adjustment process, the two components feed back the actual operating parameters to the control device in real time. When the actual value is consistent with the target value, stable operation is maintained.

[0080] In another optional approach, the control device adjusts the operating parameters of one component individually based on real-time feedback of ice transparency. For example, when the ice transparency is close to the expected level and only the cooling speed needs fine-tuning, a command is sent to the cooling component to adjust its current operating parameters to the first operating parameter value, while the power component maintains its current speed. If only the stirring speed needs adjustment, only the power component is adjusted to the second operating parameter value. Simultaneously, the control device monitors the cumulative ice-making time in real time. As the time increases, it automatically updates the first and second operating parameter values ​​according to positive and negative correlations, ensuring that the adjustment logic always adapts to the ice-making stage.

[0081] In this embodiment, the TDS value and cumulative ice-making time are divided into exclusive interval combinations, and each combination is matched with a unique target value of the operating parameter. This makes the adjustment logic clearer and more targeted, effectively avoiding speed deviation caused by fuzzy adjustment, and further improving the stability and consistency of ice transparency throughout the process. The correlation between the cumulative ice-making time and the operating parameters of the two components is clarified, so that the speed adjustment is fully aligned with the heat conduction efficiency and water quality change characteristics of the ice-making process. This solves the problem of low ice-making efficiency and decreased transparency caused by the thickening of ice in the later stage of ice making, and optimizes ice-making efficiency while ensuring ice-making quality.

[0082] The second feasible implementation method: Adjusting the operating parameter values ​​of the heat dissipation component and the power component according to the TDS value and the cumulative ice-making time includes the following steps A41 to A44: Step A41: Determine the second ice-making time interval to which the cumulative ice-making time belongs; The second ice-making time interval refers to a pre-defined, unified cumulative ice-making time interval within the control device based on the overall stage characteristics of the ice-making process. Its function is to serve as the basis for subsequent matching of TDS value intervals. Unlike the first ice-making time interval, this interval does not distinguish TDS values ​​and provides a unified ice-making stage division for all TDS value scenarios. For example, it can be divided into 0~1.5 hours, 1.5~3 hours, and 3~8 hours. The division is based on the overall change pattern of the thermal conductivity of ice during the ice-making process.

[0083] In one optional approach, the control device internally presets three unified second ice-making time intervals: 0~1.5 hours, 1.5~3 hours, and 3~8 hours, respectively. Each interval has a clearly defined time threshold. After the control device obtains the real-time cumulative ice-making time, it compares the time with the thresholds of the three intervals one by one. For example, if the cumulative ice-making time is detected to be 2 hours, it is determined that it belongs to the second ice-making time interval of 1.5~3 hours. The determination result is stored and used for subsequent steps.

[0084] In another optional approach, the control device internally presets dynamic division rules for the second ice-making time interval. Based on the rated ice-making capacity of the ice-making equipment, the total ice-making time is set and then divided into three equal phases as the second ice-making time interval. For example, if the equipment's rated total ice-making time is 8 hours, it is divided into 0-1.5 hours (initial phase), 1.5-3 hours (mid-phase), and 3-8 hours (late phase). The control device compares the real-time accumulated ice-making time with the dynamically divided intervals to determine the corresponding second ice-making time interval, ensuring that the interval division adapts to the equipment's ice-making capacity.

[0085] Understandably, by uniformly dividing the second ice-making time interval, the overall stage of the ice-making process can be clearly identified, including the initial, middle, and late stages. The characteristics of ice-making at each stage, such as high thermal conductivity in the initial stage and low thermal conductivity in the later stage, can be grasped. This provides a basis for matching a specific TDS value interval according to the ice-making stage, so that the adjustment logic first fits the ice-making stage and then adapts to the TDS value, thereby improving the accuracy of the adjustment.

[0086] Step A42: Determine the second TDS value interval to which the TDS value belongs within the second ice-making time interval; The second TDS value range refers to a separately preset TDS value range for each second ice-making time range. Its function is to work in conjunction with the second ice-making time range to form a unique adjustment combination. The second TDS value range for each second ice-making time range is determined according to the ice-making characteristics of that stage. The second TDS value range corresponding to each second ice-making time range can be the same or different. For example, the second TDS value range corresponding to each second ice-making time range includes: TDS value ≤ 150 and TDS value > 150.

[0087] In one optional approach, the control device internally presets a corresponding second TDS value range for each second ice-making time interval. For example, the initial ice-making period (0-1.5 hours) corresponds to TDS values ​​≤ 150 and > 150; the middle ice-making period (1.5-3 hours) corresponds to TDS values ​​≤ 150, 150 < TDS values ​​≤ 300, and > 300; and the later ice-making period (3-8 hours) corresponds to TDS values ​​≤ 100, 100 < TDS values ​​≤ 200, and > 200. After determining that the cumulative ice-making time belongs to the initial ice-making period, the control device retrieves the corresponding second TDS value range for that stage, compares the real-time TDS value (e.g., 120) with each second TDS value range, and determines that it belongs to the second TDS value range with a TDS value ≤ 150.

[0088] In another optional approach, the control device internally presets corresponding rules for a second TDS value interval for each second ice-making time interval. In the early stages of ice making, impurities are fewer and water quality changes are smaller, so the interval is coarser; in the later stages, more dissolved solids precipitate and TDS values ​​change significantly, so the interval is finer. For example, in the later stages of ice making, every 100 TDS values ​​constitutes one interval. After determining the ice-making stage, the control device generates the corresponding second TDS value interval in real time according to the rules for that stage, and then substitutes the detected TDS values ​​into it to determine the interval to which it belongs, ensuring that the TDS value interval closely matches the water quality change characteristics of the ice-making stage.

[0089] Understandably, since different ice-making stages have different sensitivities to TDS values, changes in TDS values ​​in the later stages of ice making have a greater impact on the transparency of ice. Therefore, matching a dedicated second TDS value range to each second ice-making time range can avoid adjustment deviations caused by using the same TDS value range for different ice-making stages, making the combination of ice-making time and TDS value more consistent with the actual ice-making process, and providing a unique matching basis for obtaining the second preset value in the future.

[0090] Step A43: Obtain a second preset value associated with the second TDS value range, wherein the second preset value includes a third operating parameter value of the heat dissipation component and a fourth operating parameter value of the power component; The second preset value refers to the target value of the operating parameters of the heat dissipation component and the power component associated with each second TDS value range. Its function is to provide a clear quantitative indicator for speed regulation, including the third operating parameter value of the heat dissipation component and the fourth operating parameter value of the power component.

[0091] In one optional approach, the control device has a pre-set association table that stores a one-to-one correspondence between each second TDS value interval and a second preset value for each second ice-making time interval. For example, during the initial ice-making period (0-1.5 hours), a TDS value ≤ 150 corresponds to a third operating parameter value (50% duty cycle for the cooling fan) and a fourth operating parameter value (120 rpm speed for the stirring motor). During the initial ice-making period and a TDS value > 150, a 30% duty cycle for the cooling fan and a 150 rpm speed for the stirring motor correspond to the second preset value. After determining the specific second TDS value interval, the control device queries the association table to obtain the corresponding second preset value based on the determined second ice-making time interval and second TDS value interval, and extracts the two operating parameter values ​​for subsequent adjustment.

[0092] Understandably, converting the range of ice-making time and TDS value into specific component operating parameter target values ​​quickly provides a quantifiable basis for subsequent adjustments, avoiding blind adjustments; at the same time, based on the exclusive calculation logic or correlation of the ice-making stage, the second preset value is made to better fit the ice-making characteristics of that stage, improving the accuracy of speed adjustment.

[0093] Step A44: Adjust the current operating parameter value of the heat dissipation component to the third operating parameter value, and adjust the current operating parameter value of the power component to the fourth operating parameter value.

[0094] The third operating parameter value refers to the target operating parameter value of the heat dissipation component in the second preset value. In this application, it is specifically the target duty cycle of the cooling fan. Its function is to clarify the specific operating status of the heat dissipation component under the corresponding ice-making time and TDS value during the icing stage.

[0095] The fourth operating parameter value refers to the target operating parameter value of the power component in the second preset value. In this application, it is specifically the target speed of the stirring motor. Its function is to clarify the specific operating status of the power component under the corresponding ice-making time and TDS value during the freezing stage.

[0096] In one optional approach, after the control device obtains the third and fourth operating parameter values, it simultaneously sends adjustment commands to the heat dissipation component and the power component. The cooling fan gradually adjusts the current duty cycle to the duty cycle corresponding to the third operating parameter value, and the stirring motor gradually adjusts the current speed to the speed value corresponding to the fourth operating parameter value. During the adjustment process, the two components provide real-time feedback on the actual operating status, and the control device performs closed-loop monitoring. When the actual value matches the target value, stable operation is maintained to ensure that the ice-making state is adapted to the current ice-making time and TDS value.

[0097] In another alternative approach, the control device selects to adjust the operating parameters of one component individually based on the freezing progress of the water in the inner tank. For example, if the freezing speed is detected to be too fast and only the cooling speed needs to be reduced, a command is sent to the cooling component to adjust it to the third operating parameter value, while the power component maintains the current speed. If the gas in the water is detected to be insufficiently discharged and only the stirring speed needs to be increased, a command is sent to the power component to adjust it to the fourth operating parameter value, while the cooling component maintains the current speed. This allows for targeted fine-tuning, reducing energy consumption and cooling loss.

[0098] In this embodiment, the overall ice-making stage is first determined, and then a dedicated TDS value range is matched. This makes the adjustment logic more consistent with the heat conduction efficiency and water quality change patterns of the ice-making process, effectively solving the adjustment deviation problem caused by the different sensitivity of TDS values ​​to different ice-making stages, and further improving the overall stability of ice transparency. In addition, each ice-making stage and TDS value range is matched with a corresponding second preset value, making the speed adjustment more precise and standardized, and avoiding fluctuations in ice quality caused by fuzzy adjustment.

[0099] For the second feasible implementation method described above, a third operating parameter value for the heat dissipation component will be determined. Considering that the actual ambient temperature will affect the accuracy of this third operating parameter value, it can be corrected. Specifically, after obtaining the third operating parameter value through the above method, the control method for the ice-making equipment further includes: Step S110: Obtain the ambient temperature of the ice-making equipment; Ambient temperature: refers to the external ambient temperature of the ice-making equipment, expressed in degrees Celsius (°C). In this embodiment, it can be detected and obtained by a temperature sensor installed on the equipment casing. Its function is to reflect the influence of the external environment on the heat dissipation efficiency of the ice-making equipment. The higher the ambient temperature, the lower the heat dissipation efficiency of the cooling fan, and vice versa. It is an important basis for correcting the operating parameter values ​​of the heat dissipation components.

[0100] In one alternative approach, an NTC temperature sensor is installed on the outside of the ice-making equipment's casing. The sensor is in direct contact with the external environment and collects analog signals of the ambient temperature in real time. The signals are then transmitted to the microprocessor of the control device. The microprocessor converts the analog signals into specific Celsius values ​​and performs a detection and data update at regular intervals. Simultaneously, the collected data is filtered to remove outliers caused by sudden changes in ambient temperature, ensuring data accuracy.

[0101] In another alternative approach, the control device of the ice-making equipment integrates an ambient temperature detection module. It collects external air through the heat dissipation holes of the ice-making equipment's casing, uses a temperature sensing element within the detection module to detect the air temperature, and directly transmits the detected temperature data to a microprocessor. The microprocessor averages the detected data to obtain a stable ambient temperature value, avoiding errors from single-point detection and providing a reliable basis for subsequent correction value calculations.

[0102] Understandably, since the actual heat dissipation effect of the heat dissipation component is significantly affected by the ambient temperature, changes in ambient temperature will lead to different icing rates at the same heat dissipation speed. After obtaining the ambient temperature, the operating parameter values ​​of the heat dissipation component can be compensated and corrected so that the heat dissipation effect is not affected by the ambient temperature and the stability of the icing rate is ensured. This is a key step in improving the adaptability of the equipment in different environments.

[0103] Step S120: Determine the correction value for the third operating parameter based on the ambient temperature; Correction value: refers to the quantitative index calculated by the control device based on the ambient temperature, used to adjust the value of the third operating parameter. In this embodiment, it is specifically the adjustment percentage of the duty cycle of the cooling fan. Its function is to compensate for the influence of ambient temperature on heat dissipation efficiency, so that the actual heat dissipation effect of the heat dissipation component matches the ice-making requirements. This value is positively correlated with the ambient temperature.

[0104] In one optional approach, the control device internally presets a table showing the correspondence between ambient temperature and correction values. Based on experimental data, it sets a correction percentage for the heat dissipation duty cycle corresponding to different ambient temperature ranges. For example, the correction value is 0% when the ambient temperature is <10℃, 2% when 10℃ ≤ ambient temperature <15℃, 4% when 15℃ ≤ ambient temperature <25℃, 7% when 25℃ ≤ ambient temperature <35℃, and 10% when 35℃ ≤ ambient temperature <40℃. The correction value increases with increasing ambient temperature, showing a positive correlation. After acquiring the ambient temperature, the control device consults the table to determine the correction value for the third operating parameter.

[0105] In another optional approach, the control device establishes a calculation model for ambient temperature and correction values. The model is based on a positive correlation logic where the correction value increases by 2% for every 5°C increase in ambient temperature. The correction value is set to a range of 0% to 10% to avoid over-correction. The control device substitutes the detected actual ambient temperature into the model to calculate the corresponding correction value. If the calculated value exceeds the range, the boundary value of 0% or 10% is used to ensure the reasonableness of the correction value for the third operating parameter.

[0106] Understandably, by converting ambient temperature into a specific heat dissipation parameter correction index and setting a positively correlated correction value, the impact of ambient temperature on heat dissipation efficiency can be compensated. The higher the ambient temperature, the larger the correction value and the higher the heat dissipation duty cycle, thereby improving the actual heat dissipation effect of the cooling fan and ensuring that the heat dissipation efficiency of the heat dissipation components is consistent under different ambient temperatures, thus maintaining a stable freezing speed and ensuring the transparency of the ice.

[0107] Step S130: Correct the third operating parameter value according to the correction value to obtain the corrected third operating parameter value, wherein the corrected value of the third operating parameter value is positively correlated with the ambient temperature; The corrected third operating parameter value refers to the final target operating parameter value of the heat dissipation component obtained by combining the third operating parameter value with the corrected value. Its purpose is to clearly consider the specific operating state of the heat dissipation component after considering the influence of ambient temperature, to ensure that the actual heat dissipation efficiency of the heat dissipation component is consistent under different ambient temperatures, and to ensure the stability of the icing rate.

[0108] In one alternative approach, the control device uses a direct superposition method for correction, adding the determined correction value directly to the acquired third operating parameter value. For example, if the third operating parameter value is 50% and the correction value corresponding to an ambient temperature of 20℃ is 4%, then the corrected third operating parameter value is 50% + 4% = 54%. During the correction process, the control device automatically verifies the result. If the corrected value exceeds 100%, then 100% is taken as the final value to ensure that the heat dissipation component operates within the rated range.

[0109] Understandably, by converting the compensation effect of ambient temperature into the final target operating parameter value of the heat dissipation component, and by correcting the third operating parameter value to adapt to the current ambient temperature, the actual heat dissipation effect of the heat dissipation component meets the ice-making requirements. This solves the problems of fluctuating heat dissipation efficiency and unstable icing speed caused by changes in ambient temperature. It also makes the speed adjustment not only fit the ice-making time and TDS value, but also take into account the influence of the external environment, further improving the accuracy of the adjustment.

[0110] Step S140: Adjust the current operating parameter value of the heat dissipation component to the corrected third operating parameter value.

[0111] In one alternative approach, after the control device obtains the corrected third operating parameter value, it sends a precise speed adjustment command to the heat dissipation component. The cooling fan gradually adjusts the power supply duty cycle according to the command, smoothly transitioning from the current duty cycle to the duty cycle corresponding to the corrected third operating parameter value. During the adjustment process, the control device receives the speed feedback signal of the cooling fan in real time. If the actual duty cycle deviates from the target value by more than 2%, a fine-tuning command is sent to achieve closed-loop regulation and ensure stable heat dissipation effect.

[0112] In another optional approach, the control device uses a segmented adjustment method based on the current operating status of the heat dissipation component. The difference between the current duty cycle and the corrected third operating parameter value is divided into 2 to 3 adjustment stages. Each stage adjusts a certain duty cycle. For example, the duty cycle is adjusted from 50% to 54% in two stages. First, it is adjusted to 52%, stabilized for 10 seconds, and then adjusted to 54%. This avoids sudden changes in the speed of the cooling fan caused by a one-time adjustment, reduces component impact, extends service life, and ensures a smooth transition of the heat dissipation effect.

[0113] Understandably, by adjusting the heat dissipation components to the corrected third operating parameter value, the heat dissipation efficiency is not affected by the ambient temperature. In high-temperature environments, the heat dissipation speed is increased to ensure the heat dissipation effect, while in low-temperature environments, the basic heat dissipation speed is maintained to save energy. This ensures that the freezing speed remains stable under different ambient temperatures, thereby ensuring the consistency of ice transparency. At the same time, the smooth adjustment method reduces component wear and improves the reliability of the equipment.

[0114] In this embodiment, the influence of external ambient temperature on heat dissipation efficiency is considered. By compensating for the effect of ambient temperature through a correction value, the actual heat dissipation efficiency of the heat dissipation component remains consistent under different ambient temperatures. This solves the problems of unstable freezing speed and fluctuating ice transparency caused by changes in ambient temperature, and improves the environmental adaptability of the equipment in different regions and seasons. Furthermore, the setting of the correction value being positively correlated with ambient temperature makes the heat dissipation adjustment more in line with actual heat dissipation needs. In high-temperature environments, the heat dissipation speed is increased to ensure ice-making efficiency, while in low-temperature environments, the heat dissipation speed is reduced to save energy, achieving a balance between ice-making efficiency and energy saving.

[0115] Similarly, for the first feasible implementation described above, a first operating parameter value for the heat dissipation component is determined. Considering that the actual ambient temperature will affect the accuracy of this first operating parameter value, it can be corrected. Specifically, after obtaining the third operating parameter value through the above method, the control method for the ice-making equipment further includes: acquiring the ambient temperature where the ice-making equipment is located; determining a correction value for the first operating parameter value based on the ambient temperature; correcting the first operating parameter value according to the correction value to obtain a corrected first operating parameter value, wherein the correction value of the first operating parameter value is positively correlated with the ambient temperature; and adjusting the current operating parameter value of the heat dissipation component to the corrected first operating parameter value. The specific correction method is similar to the correction method for the third operating parameter value described above. Similar to determining the correction value for the third operating parameter, the aforementioned determination of the correction value for the first operating parameter based on ambient temperature includes: a pre-set correspondence table between ambient temperature and correction value within the control device, setting a heat dissipation duty cycle correction percentage for different ambient temperature ranges; the control device queries the correspondence table after acquiring the ambient temperature to determine the corresponding correction value; or, the control device establishes a calculation model between ambient temperature and correction value, the calculation model being based on a positive correlation logic that the correction value increases by 2% for every 5°C increase in ambient temperature, while setting the range of the correction value to 0%~10%; the control device substitutes the ambient temperature into the calculation model to calculate the corresponding correction value, and if the calculated value exceeds the range, the boundary value of 0% or 10% is taken as the correction value for the first operating parameter.

[0116] Based on the above embodiments of this application, in the fourth embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 4 The control methods for ice-making equipment include: Step S10: During the ice-making process, acquire the TDS value inside the ice-making device detected by the detection component; Step S50: Obtain the cumulative ice-making time of the ice-making equipment, and obtain the water temperature in the ice-making equipment; In step S70, if the water temperature is greater than or equal to the preset temperature, the current operating parameter value of the heat dissipation component is adjusted to the first preset operating parameter value, and the current operating parameter value of the power component is adjusted to the second preset operating parameter value.

[0117] The first preset operating parameter value refers to the target operating parameter value of the heat dissipation component preset within the control device when the water temperature is greater than or equal to a preset water temperature. This first preset operating parameter value can be the maximum duty cycle of the cooling fan or a value with a large duty cycle. For example, in this embodiment, the duty cycle of the cooling fan is 95%, which ensures that the heat dissipation component runs at full speed during the water cooling stage, thereby improving cooling efficiency, accelerating the water cooling speed, and shortening the overall ice-making time.

[0118] The second preset operating parameter value refers to the target operating parameter value of the power component preset within the control device when the water temperature is greater than or equal to the preset water temperature. This second preset operating parameter value can be the minimum speed of the power component or a lower speed value. For example, in this embodiment, it is specifically the low speed of the stirring motor, such as 60 rpm. Its function is to make the water temperature uniform through low-speed stirring during the water cooling stage, avoiding excessively rapid local cooling, and avoiding the loss of cooling capacity and noise problems caused by high-speed stirring.

[0119] In one optional approach, the control device presets a water temperature, as well as a first preset operating parameter value and a second preset operating parameter value. When the control device detects that the water temperature is higher than the preset water temperature, it determines that the water is in the cooling stage and simultaneously sends adjustment commands to the heat dissipation component and the power component. The cooling fan quickly increases its current duty cycle to the first preset operating parameter value to achieve full-speed cooling, and the stirring motor adjusts its current speed to the second preset operating parameter value to achieve low-speed uniform stirring. After the adjustment is completed, the operating state is maintained until the water temperature drops below the preset water temperature.

[0120] In another optional approach, the control device has a preset buffer mechanism for water temperature determination. Only when the detected water temperature is greater than or equal to the preset water temperature and this state continues for a certain period of time is the water determined to be in a stable cooling phase. Then, it sends an instruction to the heat dissipation component to adjust to the first preset operating parameter value and an instruction to the power component to adjust to the second preset operating parameter value. This avoids misjudgment and frequent adjustments caused by instantaneous fluctuations in water temperature. During the adjustment process, the heat dissipation component gradually increases the duty cycle, and the power component gradually decreases the speed to ensure smooth operation of the components and reduce component impact.

[0121] Understandably, when the water temperature is greater than or equal to the preset water temperature, the water has not yet entered the freezing stage. At this time, the need is to improve cooling efficiency and shorten the overall ice-making time. By adjusting the heat dissipation components to the first preset operating parameter value at full speed, the cooling efficiency is maximized and the water temperature is accelerated. At the same time, the power components are adjusted to the second preset operating parameter value at low speed to make the water temperature uniform and avoid localized excessively rapid cooling. In addition, low-speed stirring can reduce cold loss and noise, thus solving the problems of low efficiency and high energy consumption caused by fine-tuning during the cooling stage.

[0122] Step S60: If the water temperature is lower than the preset water temperature, adjust the operating parameter values ​​of the heat dissipation component and the power component according to the TDS value and the cumulative ice-making time.

[0123] In this embodiment, during the cooling phase, the heat dissipation component operates at full speed to improve cooling efficiency, while the power component operates at low speed to ensure uniform water temperature. This effectively shortens the water cooling time and improves the overall ice-making efficiency of the ice-making equipment, solving the problem of low cooling efficiency caused by single control throughout the entire process in traditional ice makers. During the freezing phase, the operating parameters of the heat dissipation component and the power component are adjusted based on the TDS value and cumulative ice-making time to improve ice transparency. Thus, through the coordination of the cooling and freezing phases, not only is cooling efficiency improved, but the transparency of the ice is also enhanced.

[0124] Based on the above embodiments of this application, in the fifth embodiment of this application, the content that is the same as or similar to the above embodiments can be referred to the above description, and will not be repeated hereafter. On this basis, the control method for the ice-making equipment includes: Step S80: When the ice-making equipment is started, obtain the TDS value inside the ice-making equipment; Ice-making equipment startup: This refers to the moment when the ice-making equipment is powered on and the user issues an ice-making command. The refrigeration system, detection components, etc., begin to initialize. This is the initial stage of the ice-making process, and its purpose is to prepare for the ice-making process. At this time, TDS value detection can be performed to determine in advance whether the water quality is suitable for making transparent ice, providing a basis for subsequent ice-making control and user prompts.

[0125] In one possible approach, after the ice-making equipment is powered on and receives the user's ice-making command, the control device immediately sends a start detection command to the detection component. The detection component makes full contact with the water to be made in the inner tank, detects the initial conductivity of the water, and transmits the conductivity analog signal to the microprocessor on the motherboard. The microprocessor quickly converts the conductivity data into a TDS value through a preset mapping relationship between conductivity and TDS value.

[0126] In another possible approach, when the ice-making equipment starts up, the detection component automatically enters the initialization detection mode. The probe on the top cover does not require a separate command from the control device; it directly detects the conductivity of the ice-making water inside the tank. At the same time, the detection signal is filtered to remove circuit interference signals at the moment of equipment startup, ensuring the accuracy of the conductivity data. Subsequently, the processed effective conductivity signal is transmitted to the microprocessor. The microprocessor calls the preset mapping relationship between conductivity and TDS value to directly match the initial TDS value. After completing the detection, the detection result is fed back to the control device, providing data support for the next step of judgment.

[0127] Understandably, obtaining the initial TDS value before the ice-making equipment officially starts making ice can help predict whether the water quality meets the requirements for high-transparency ice making. This avoids the ice-making equipment blindly entering the ice-making process when the water quality is too hard, reducing energy waste caused by ineffective ice making and providing a basis for determining whether to output prompt information later.

[0128] Step S90: If the TDS value obtained at startup is greater than the preset TDS value, output a prompt message, wherein the prompt message is used to indicate that the TDS value in the ice-making device is high.

[0129] Preset TDS value: refers to the TDS value preset inside the control device. For example, in this embodiment, the preset TDS value is set to 400, which serves as a criterion for judging whether the water quality is suitable for making high-transparency ice. When the TDS value is greater than the preset TDS value, the content of dissolved substances in the water is too high, and even if the rotation speed is adjusted, it is difficult to ensure the high transparency of the ice. At this time, a prompt needs to be issued to the user.

[0130] The prompt message refers to the signal form in which the ice-making equipment conveys information about a high TDS value to the user. Its function is to remind the user that the current water quality is not suitable for making high-transparency ice. In the embodiments of this application, it can be implemented through indicator lights, buzzers, displays, etc. of the ice-making equipment.

[0131] In one possible implementation, the control device internally stores a preset TDS value, for example, a preset TDS value set to 400. The acquired initial TDS value is compared with this preset TDS value. If a TDS value of 450 is detected, which is greater than 400, the control device immediately sends a command to the device's prompting module to trigger a multi-form prompt. For example, the red indicator light on the front of the ice maker flashes at a frequency of 1 time per second, the buzzer emits three intermittent prompt sounds in a "beep-beep" rhythm, and at the same time, the device's digital display screen directly displays the text prompt "Water quality is too hard, affecting ice transparency." After the prompt message lasts for 10 seconds, the text prompt remains constantly displayed, the indicator light stops flashing, until the user manually resets or changes the water quality.

[0132] In another possible implementation, the control device sets a graded judgment based on the comparison result between the initial TDS value and the preset TDS value. If the TDS value obtained at startup is greater than the preset TDS value, the content of dissolved substances in the water is first determined. For example, 400 < TDS value ≤ 500 is considered slightly exceeding the standard, and TDS value > 500 is considered severely exceeding the standard. Then, the corresponding level of prompt information is output: when slightly exceeding the standard, the yellow indicator light of the ice maker is constantly lit, and the display shows "Water quality is too hard, ice transparency is reduced"; when severely exceeding the standard, the red indicator light flashes, the buzzer continuously sounds for 5 seconds, and the display shows "Water quality is seriously exceeding the standard, it is recommended to replace with purified water". At the same time, the control device retains the record of exceeding the standard and reminds the user again when starting the device next time. All prompt information can be manually turned off by the user through the device button.

[0133] In this embodiment, an initial TDS value test is performed before the device officially starts making ice. If the TDS value is high, a prompt message is triggered, which can promptly inform the user of water quality issues and let the user know that the current water quality is affecting the production of high-transparency ice cubes. This prevents users from unknowingly producing substandard transparent ice, thus improving the user interactivity and user experience of the ice-making device. At the same time, this step is only a prompt and does not interrupt the ice-making process. If the user does not need to make high-transparency ice, they can continue to make ice normally, thus balancing prompting and flexibility of use.

[0134] For example, in order to help understand the implementation process of the control method of the ice-making equipment obtained by combining the above embodiments, the implementation process of the control method of the ice-making equipment of this application will be described below by way of example.

[0135] An example of the overall control logic of the control method for the ice-making equipment in this application is as follows: ① TDS value less than or equal to 150: 0~2 hours, stirring motor 120rpm, cooling fan duty cycle 50%.

[0136] 2-4 hours, stirring motor at 60 rpm, cooling fan duty cycle at 70%.

[0137] After 4-7 hours, the stirring motor stops, and the cooling fan operates at 90% duty cycle.

[0138] ② TDS value greater than 150 and less than or equal to 400: 0~2.5 hours, stirring motor 150rpm, cooling fan duty cycle 30%.

[0139] 2.5-5 hours, stirring motor at 80 rpm, cooling fan duty cycle at 50%.

[0140] 5-9 hours, stirring motor at 80 rpm, cooling fan duty cycle at 70%.

[0141] ③ If the TDS value is greater than 400, the machine will issue a warning that the water is too hard and will affect the transparency of the ice.

[0142] There are three possible extension schemes: First: Speed ​​extension scheme based on time and temperature control: Start making ice; First, the TDS value is checked. If the TDS value is greater than 400, the machine will issue a warning that the water is too hard and will affect the transparency of the ice cubes. However, it will not affect the subsequent production process.

[0143] Then perform temperature detection, and then perform water temperature detection every 30 seconds; When the water temperature is ≥2℃, the stirring motor operates at 60rpm and the cooling fan operates at 95% duty cycle. At this speed, the water does not begin to freeze.

[0144] When the water temperature is <2℃, the TDS value is measured once. At the same time, the timer starts counting.

[0145] ① TDS value less than or equal to 150: 0-1 hour, stirring motor 120rpm, cooling fan duty cycle 50%.

[0146] 1-3 hours, stirring motor at 60rpm, cooling fan at 70% duty cycle.

[0147] After 3-7 hours, the stirring motor stops, and the cooling fan operates at 85% duty cycle.

[0148] ② TDS value greater than 150 and less than 400: 0~1.5 hours, stirring motor 150rpm, cooling fan duty cycle 30%.

[0149] 1.5-4 hours, stirring motor 80rpm, cooling fan duty cycle 50%.

[0150] 4-8 hours, stirring motor at 80rpm, cooling fan duty cycle at 70%.

[0151] This extended solution uses NTC to identify the cooling time before freezing, and employs a high duty cycle for heat dissipation during this stage, which improves the efficiency of the cooling phase and helps reduce overall production time.

[0152] Second: Extended solution for dynamic TDS value monitoring and adjustment: Start making ice; First, the TDS value is checked. If the TDS value is greater than 400, the machine will issue a warning that the water is too hard and will affect the transparency of the ice cubes. However, it will not affect the subsequent production process.

[0153] Then perform temperature detection, and then perform water temperature detection every 30 seconds; When the water temperature is ≥2℃, the stirring motor operates at 60rpm and the cooling fan operates at 95% duty cycle. At this speed, the water does not begin to freeze.

[0154] When the water temperature is <2℃, the TDS value is measured every 2-3 minutes. At the same time, the timer starts.

[0155] 0~1.5 hours: When the TDS value is less than or equal to 150, the stirring motor operates at 120 rpm and the cooling fan operates at 50% duty cycle.

[0156] When the TDS value is greater than 150, the stirring motor operates at 150 rpm and the cooling fan operates at 30% duty cycle.

[0157] 1.5-3 hours: When the TDS value is less than or equal to 150, the stirring motor operates at 60 rpm and the cooling fan operates at 70% duty cycle.

[0158] When the TDS value is greater than 150, the stirring motor operates at 80 rpm and the cooling fan operates at 50% duty cycle.

[0159] 3-8 hours: When the TDS value is less than or equal to 150, the stirring motor stops and the cooling fan operates at 85% duty cycle.

[0160] When the TDS value is greater than 150, the stirring motor operates at 80 rpm and the cooling fan operates at 70% duty cycle.

[0161] This extended scheme uses dynamic TDS adjustment, which is more effective for medium-hardness water. It can be switched to this control scheme after the water is initially determined to be of medium hardness. This is because during ice making, dissolved substances precipitate out, causing a significant increase in the hardness of the remaining liquid water. It's also possible that dissolved substances freeze in the ice, depending on the solubility differences of the types of dissolved substances, such as ions, insoluble salts, and organic particles.

[0162] Third: An extended solution for adjusting the ambient temperature determination: Start making ice; First, the TDS value is checked. If the TDS value is greater than 400, the machine will issue a warning that the water is too hard and will affect the transparency of the ice cubes. However, it will not affect the subsequent production process.

[0163] Then, temperature detection is performed, including water temperature detection every 30 seconds and ambient temperature detection. When the water temperature is ≥2℃, the stirring motor operates at 60rpm and the cooling fan operates at 95% duty cycle. At this speed, the water does not begin to freeze.

[0164] When the water temperature is <2℃, the TDS value is measured every 2-3 minutes. At the same time, the timer starts.

[0165] 0~1.5 hours: When the TDS value is less than or equal to 150, the stirring motor operates at 120 rpm and the cooling fan duty cycle is 40%+n.

[0166] When the TDS value is greater than 150, the stirring motor operates at 150 rpm and the cooling fan duty cycle is 30+n.

[0167] 1.5-4 hours: When the TDS value is less than or equal to 150, the stirring motor operates at 60 rpm and the cooling fan duty cycle is 60+n.

[0168] When the TDS value is greater than 150, the stirring motor operates at 80 rpm and the cooling fan duty cycle is 40+n.

[0169] 3-8 hours: When the TDS value is less than or equal to 150, the stirring motor stops and the cooling fan duty cycle is 75+n.

[0170] When the TDS value is greater than 150, the stirring motor operates at 80 rpm and the cooling fan duty cycle is 60+n.

[0171] The duty cycle mentioned above has a variation range of approximately 10%, and this value is determined based on the impact of ambient temperature on heat dissipation efficiency. If Tv < 10℃, n = 0; Tv < 15℃, n = 2; Tv < 25℃, n = 4; Tv < 35℃, n = 7; Tv < 40℃, n = 10.

[0172] This extended solution uses an adjustment with ambient temperature determination. For multi-ambient-temperature operating conditions, it can take into account the impact of ambient temperature on heat dissipation efficiency and ice-making speed, avoiding excessively fast ice-making speed at low ambient temperatures, which would affect the ice-making speed.
