[0026] As shown in Figure 1, the present application provides an exemplary ice maker comprising a control unit 1, a temperature sensor 2, an ice mold 3, and a heat exchange mechanism 8. The control unit 1 is used to control the operation of the entire machine. Its functions include, but are not limited to, obtaining the real-time temperature detected by the temperature sensor 2, determining the corresponding ambient temperature based on the real-time temperature, determining the corresponding ice formation and ice-deflation times based on the ambient temperature, and controlling the heat exchange mechanism 8 to perform ice making and ice-deflation operations based on the ice formation and ice-deflation times. The ice mold 3 is provided with multiple ice molds. After each ice mold is filled with liquid, ice cubes are formed through the ice-making process, and the deflation process allows the formed ice cubes to be released from the ice mold. The ice mold 3 can be connected to a water source to supply liquid to the ice mold 3. The liquid used to make ice can be not only liquid water, but other ingredients, such as cheese or sugar, can also be added as needed, without affecting the inventive spirit of the present application.

[0027] In some embodiments, the water source can be a water tank connected to the ice-making mold 3 and filled with liquid. An ice trough can be provided above the water tank to hold the ice cubes after the ice-making mold 3 is demolded. A water outlet can be provided below the ice trough so that the water droplets melted from the ice cubes in the ice trough can flow back into the water tank for reuse, thereby saving water. Accordingly, the control unit 1 can control a flip mechanism to transmit torque to the rotating shaft of the ice-making mold 3, causing the ice-making mold 3 to rotate and load the slightly melted and loosened ice cubes into the ice trough. It is not difficult to understand that when the melted water from the ice cubes in the water tank falls back into the water tank, the temperature of the liquid in the water tank will be affected to a certain extent, which will also result in a slight reduction in the ice-making time required when the liquid in the water tank is subsequently used to make ice.

[0028] Referring to Figure 2 , the heat exchange mechanism 8 includes a compressor 81, a condenser, a control valve 82, and an evaporator. The evaporator is connected to the compressor 81, which is in turn connected to the condenser, which is then connected to the evaporator, forming an ice-making circuit. Refrigerant flows through the ice-making circuit. When the refrigerant flows to the evaporator, it absorbs heat from the outside world and lowers the ambient temperature. When the refrigerant flows to the condenser, it releases heat to the outside world. This ice-making circuit is controlled by the control valve 82. When the control valve 82 is open, the refrigerant flows through the evaporator, absorbing heat. When the control valve 82 is closed, the refrigerant does not flow through the evaporator, allowing the evaporator to gradually heat up due to the influence of the ambient temperature. Of course, the control valve 82 can also be configured as a reversing valve through piping design, so that in the first reversing state, the refrigerant is directed to the evaporator in a heat-absorbing state, and in the second reversing state, the refrigerant is directed to the evaporator in a heat-releasing state.

[0029] The evaporator in the heat exchange mechanism 8 is thermally connected to the ice mold 3 to ensure good heat conduction between the evaporator and the ice molds in the ice mold 3, ensuring smooth ice making and ice removal. The compressor 81 and control valve 82 in the heat exchange mechanism 8 are both electrically connected to the control unit 1, so that the control unit 1 sends an electrical signal to the control valve 82, thereby causing the evaporator to cool or heat the ice mold 3, thereby implementing ice making or ice removal accordingly.

[0030] In the present application, one or more temperature sensors 2 may be provided, each of which is electrically connected to the control unit 1 to provide the collected real-time temperature to the control unit 1. In terms of mechanical structure, the temperature sensors 2 may be discretely distributed around the ice maker or fixed to the ice maker, for example, to the housing of the ice maker, as long as the actual temperature of the physical space where the ice maker is located is collected as accurately as possible.

[0031] For example, the temperature sensor 2 can adopt an NTC temperature sensor, which has a relatively controllable cost. The real-time temperature measured by the NTC temperature sensor may have an error with the actual temperature. Therefore, in order to ensure the accuracy of the real-time temperature collected by the temperature sensor 2, the real-time temperature can also be corrected accordingly as needed.

[0032] It should be pointed out that the mechanical structure and electrical structure of the ice maker of the present application can be implemented flexibly and are not limited to the above examples. As long as the mechanical structure and electrical structure implemented still follow the above examples, it does not hinder the application of the ice making demoulding control method of the present application.

[0033] In the solutions previously explored by the applicant, it was discovered that in conventional technologies, while the ice-making time of ice-makers is generally fixed according to experimental or empirical values, while this ensures the formation of ice cubes in most cases, it can also lead to anomalies. This is primarily due to the fact that the ambient temperature of the space where the ice-making machine is located varies with the weather. Under different ambient temperatures, the operating temperature of the ice-making machine fluctuates during the first few rounds of ice-making after it is turned on. The liquid temperature and the ambient temperature generally also fluctuate in a correlated manner. This, combined with multiple variables, can sometimes cause ice cubes to fail to form completely during the first few rounds of ice-making according to the fixed ice-making time. Sometimes, multiple ice cubes may freeze into a single piece, commonly known as "connected ice," which can be considered an ice-making failure to some extent. Only when all these variables are relatively stable can the ice-making effect of the ice-making machine be relatively stable.

[0034] In addition, in addition to the fact that the ice making effect in the first few rounds cannot be guaranteed, when the ambient temperature is too low, even if the ice making time is set, it is still possible that the ice cubes will be stuck together due to the low ambient temperature. Once the ice cubes are stuck together, it will affect the release of the ice cubes from the mold and cause the ice maker to malfunction.

[0035] In order to solve one of the above problems, based on the above exemplary product architecture and working principle of the ice maker, the ice making and demoulding control method of the present application can be implemented as a computer program product, stored in the memory inside the control unit 1 of the ice maker, and called from the memory by the central processing unit in the control unit 1 and run. During operation, the heat exchange mechanism 8 is determined to determine the ice making time and ice removing time corresponding to ice making and ice removing for the ice making mold 3 according to the ambient temperature collected by each temperature sensor 2, and the heat exchange mechanism 8 is controlled to work according to the corresponding ice making time and ice removing time, so as to realize the full automation operation of refrigeration and ice removing.

[0036] Referring to FIG3 , in one embodiment, the ice making and demoulding control method of the present application is executed by the control unit of the ice making machine, and includes:

[0037] Step S5100: obtaining the ambient temperature of the physical space where the ice maker is located;

[0038] When ice cubes need to be made, the ice maker of the present application can be used to make ice. After ice making is completed, the ice can be removed from the mold. After the ice maker is started, one or more temperature sensors electrically connected to the control unit of the ice maker enter an operating state and continuously collect temperature data. The control unit can determine the ambient temperature of the physical space where the ice maker is currently located based on this temperature data, thereby effectively detecting the actual temperature of the physical space.

[0039] In embodiments where the ambient temperature is determined using temperature data from multiple temperature sensors, the multiple temperature sensors are relatively discretely distributed, determining corresponding temperature data at different locations relative to the ice maker. The individual temperature data can then be fused to determine a single ambient temperature, serving as the actual temperature of the physical space. The ambient temperature can be uniformly expressed in degrees Celsius or in degrees Kelvin, without affecting the inventive spirit of the present application.

[0040] Step S5200: determining an ice-forming time corresponding to the ambient temperature according to the first mapping relationship, and controlling a heat exchange mechanism in the ice-making machine to make ice for an ice-making mold in the ice-making machine according to the ice-forming time;

[0041] The relationship between ambient temperature and ice formation time is linear, and a mapping relationship between ambient temperature and ice formation time is pre-set as a first mapping relationship. The representation of the first mapping relationship can be flexibly set. In one embodiment, the first mapping relationship can be expressed as a mapping relationship table; in another embodiment, the first mapping relationship can be expressed as a data formula after data fitting. It is not difficult to understand that based on the linear relationship between ambient temperature and ice formation time, after the first mapping relationship is pre-determined, the corresponding ice formation time for a given ambient temperature can be determined based on the first mapping relationship.

[0042] The first mapping relationship can be constructed based on a pre-prepared first data source. The first data source for constructing the first mapping relationship can be obtained by conducting actual measurements on the ice maker or its products from the same batch to obtain the actual ice-making time of each ice maker under multiple ice-making rounds based on the ambient temperature corresponding to each ice-making round, from the moment when the heat exchange mechanism is controlled to start ice-making to the moment when the ice cubes in the ice-making mold are just formed and there is no connection between the ice cubes. Therefore, each ambient temperature has its corresponding ice-forming time, forming data pairs, and these data pairs can be used to construct the first mapping relationship.

[0043] After determining the ice-forming time corresponding to the ambient temperature according to the first mapping relationship, the ice-forming time can be set as the corresponding working time for the heat exchange mechanism of the ice maker to make ice for the ice-making mold, and then the heat exchange mechanism is started to work to implement the ice-making process for the liquid in each ice mold in the ice-making mold.

[0044] Specifically, the control unit can set a timer based on the determined ice formation time, start the timer to begin timing, and synchronously control the compressor in the heat exchange mechanism to start working. At the same time, the control valve in the heat exchange mechanism is switched to allow the refrigerant to act on the evaporator, so that the evaporator is in a working state that absorbs heat relative to the ice-making mold. The heat of the ice-making mold is carried away by the refrigerant, thereby achieving cooling. During the cooling process, the liquid in the ice mold gradually freezes. When the timer set by the control unit calculates that the ice formation time has expired, it can stop working and stop passing the refrigerant for heat absorption to the evaporator. At this time, the liquid in the ice mold of the ice-making mold just forms well-shaped ice cubes, and there is basically no connection between the ice cubes, just right.

[0045] It can be seen that since the first mapping relationship has been pre-set, the relationship between the ambient temperature and its corresponding optimal ice-forming time has been pre-defined in the first mapping relationship. Therefore, when the ambient temperature is given, its corresponding ice-forming time can be quickly determined, and the automatic refrigeration control of the heat exchange mechanism can be completed without manual intervention. The ambient temperature itself is the result of the comprehensive influence of various possible variables. For example, the impact of ice cubes on the air temperature of the physical space after demolding will also be reflected in the ambient temperature. Although the ambient temperature may change continuously during the ice-making process of multiple rounds of ice-making by the ice-making machine, the change in ice-forming time corresponding to such change can also be determined based on the first mapping relationship. Therefore, whether the ice-making machine is making ice for the first round or in the past rounds, it can ensure that the heat exchange mechanism is controlled to make ice according to the ambient temperature of each round and its corresponding optimal ice-forming time.

[0046] Step S5300: Determine the defrosting time corresponding to the ambient temperature according to the second mapping relationship, and after the ice making process is completed, control the heat exchange mechanism in the ice maker to defrost the ice making mold according to the defrosting time.

[0047] Similarly, the relationship between ambient temperature and defrosting time is also a linear relationship. A mapping relationship between ambient temperature and defrosting time is pre-determined as a second mapping relationship. Similarly, the representation of the second mapping relationship can be flexibly set. In one embodiment, the second mapping relationship can be expressed as a mapping relationship table; in another embodiment, the second mapping relationship can be expressed as a data formula after data fitting. It is easy to understand that based on the linear relationship between ambient temperature and defrosting time, once the second mapping relationship is pre-determined, the corresponding defrosting time for a given ambient temperature can be determined based on the second mapping relationship.

[0048] The second mapping relationship can be constructed based on a pre-prepared second data source. The second data source for constructing the second mapping relationship can be obtained by conducting actual measurements on the ice maker or its products from the same batch, and obtaining the defrosting time experienced by each ice maker from the moment when defrosting actually begins based on the ambient temperature corresponding to each ice making round in multiple ice making rounds to the moment when the ice cubes in the ice making mold just loosen from the ice mold. Therefore, each ambient temperature has its corresponding defrosting time, forming a data pair, which can be used to construct the second mapping relationship.

[0049] After determining the defrosting time corresponding to the ambient temperature according to the second mapping relationship, the defrosting time can be set as the corresponding working time of the heat exchange mechanism of the ice maker to implement defrosting for the ice-making mold, and then the heat exchange mechanism is started to work to implement the defrosting process for the ice cubes in each ice mold in the ice-making mold.

[0050] Specifically, the control unit can set a timer based on the predetermined defrosting duration, start the timer, and synchronously control the compressor in the heat exchange mechanism to start operating. Simultaneously, the control valve in the heat exchange mechanism switches to prevent refrigerant from flowing into the evaporator, or to allow refrigerant to flow into the evaporator but release heat, thereby placing the evaporator in a state of heat release relative to the ice mold. Due to this relative heat release, the ice mold gradually warms up, and during this warming process, the outer layer of ice in the mold gradually melts. When the timer set by the control unit reaches the end of the defrosting duration, it can stop, stopping the evaporator from releasing heat. At this point, the ice mold in the ice mold is properly separated from the ice cubes within it, making it easier to release the ice cubes. Furthermore, as needed, the control unit can control the ice mold to flip, allowing the loosened ice cubes in each mold to fall under their own weight into the ice trough of the ice maker, completing the release process for one ice making cycle.

[0051] As can be seen, since the second mapping relationship has been pre-set, it predefines the relationship between the ambient temperature and its corresponding optimal defrosting time. Therefore, given the ambient temperature, the corresponding defrosting time can be quickly determined, completing automated refrigeration control of the heat exchange mechanism without manual intervention. The ambient temperature itself is the result of the combined influence of various possible variables. For example, the impact of ice cubes on the air temperature of the physical space after being demolded will also be reflected in the ambient temperature. Although the ambient temperature may change continuously during the ice maker's multiple rounds of ice making, the corresponding changes in defrosting time can also be determined based on the second mapping relationship. Therefore, regardless of whether the ice maker is making ice for the first or subsequent rounds, it can ensure that the ambient temperature of each round controls the heat exchange mechanism to implement defrosting according to its corresponding optimal defrosting time.

[0052] According to the above embodiments, it is not difficult to understand that the present application first obtains the ambient temperature of the physical space where the ice maker is located, adapts to the needs of ice making, utilizes the first mapping relationship between the ambient temperature and the ice-forming time, determines the ice-forming time required for cooling the ice making according to the ambient temperature, and controls the heat exchange device of the ice maker to operate according to the ice-forming time, so as to continuously cool the ice-making mold to achieve refrigeration so that the ice cubes are formed; adapts to the needs of demolding after the ice cubes are made, utilizes the second mapping relationship between the ambient temperature and the ice-defrosting time, determines the ice-defrosting time required for heating the demolding according to the ambient temperature, and controls the heat exchange device of the ice maker to operate according to the ice-defrosting time, so as to continuously cool the ice-making mold so that the ice cubes formed in the ice-making mold are moderately melted and loosened, so as to complete demolding. Therefore, the present application realizes the intelligent and adaptive determination of the ice-forming time and the ice-defrosting time according to the ambient temperature, and flexibly controls the entire ice-making process of the ice-making machine accordingly, so that the ice-making and ice-defrosting time control of the ice-making machine is exempted from the interference of multiple variables, especially from the interference of factors such as the ambient temperature changes of the physical space in which it is located and the operating temperature of the ice-making machine itself, and can prepare ice cubes with complete shapes, and there will be no ice bridging between the ice cubes, which effectively improves the output quality of the ice-making machine and contributes to the popularization and application of the ice-making machine.

[0053] Based on any embodiment of the method of the present application, referring to FIG. 4 , obtaining the ambient temperature of the physical space where the ice maker is located includes:

[0054] Step S5110: acquiring real-time temperatures collected by a plurality of discretely distributed temperature sensors;

[0055] As previously mentioned, an ice maker can be equipped with multiple temperature sensors, each of which can be relatively discretely distributed—for example, some located close to the ice mold and others located further away. Because these sensors are located at different distances from the heat exchange mechanism and ice mold in the ice maker, the temperature data collected by each sensor, and thus the real-time temperature, may differ. This data can then be merged.

[0056] Step S5120: Correct the deviation of each real-time temperature according to the compensation temperature corresponding to the real-time temperature to obtain the correction temperature corresponding to each real-time temperature;

[0057] The real-time temperature measured by a temperature sensor often deviates from the actual ambient temperature. This deviation can be overcome by compensating the real-time temperatures measured by each temperature sensor. Therefore, the ice maker can be placed in an experimental environment and run multiple rounds of ice making. The error between the real-time temperature and the ambient temperature corresponding to each ice-making round is obtained, forming a data pair of real-time temperature and error temperature. After data fitting, the mapping relationship between the real-time temperature and its error temperature is determined. Based on this mapping relationship, the corresponding error temperature can be obtained for the real-time temperature of the temperature sensor, which serves as the compensation temperature corresponding to the real-time temperature.

[0058] It is not difficult to understand that each temperature sensor has a mapping relationship between its corresponding real-time temperature and its error temperature. Based on this, the real-time temperature measured by each temperature sensor can be used to determine its corresponding compensation temperature according to the mapping relationship of the corresponding temperature sensor.

[0059] By adding each real-time temperature and its corresponding compensation temperature, the deviation of the real-time temperature can be corrected, thereby obtaining the corresponding correction temperature.

[0060] Step S5130: fuse the various correction temperatures to obtain the ambient temperature of the space where the ice maker is located.

[0061] Since the ice maker uses multiple temperature sensors to collect temperature data and obtain corresponding correction temperatures, each correction temperature may also be different from each other. Therefore, it is necessary to merge these correction temperatures into the same ambient temperature.

[0062] In one embodiment, when determining the ambient temperature based on the correction temperatures corresponding to the temperature sensors, the correction temperatures may be directly arithmetic averaged to obtain the average value as the ambient temperature, thereby achieving efficient calculation.

[0063] In another embodiment, given the distribution of temperature sensors at different locations relative to the ice maker, the measurement of the actual temperature of the physical space where the ice maker is located may have varying degrees of deviation. For example, the correction temperature corresponding to the real-time temperature measured by a temperature sensor located near the exhaust vent of the ice maker's heat exchange mechanism may be slightly higher than the correction temperature corresponding to the real-time temperature measured by a temperature sensor located farther from the exhaust vent. Similarly, the correction temperature corresponding to a temperature sensor located near the ice mold or evaporator may be lower than the correction temperature corresponding to a temperature sensor located farther from the ice mold or evaporator. To address this situation, weights corresponding to the temperature sensors can be pre-set, and the weighted average of the correction temperatures corresponding to the temperature sensors can be calculated based on these weights to represent the ambient temperature. The ambient temperature determined in this manner generally more accurately reflects the actual temperature of the physical space where the ice maker is located.

[0064] The above embodiments show that by using multiple temperature sensors to collect the real-time temperature of the physical space where the ice maker is located, the compensation temperature corresponding to each real-time temperature is determined by using a priori mapping relationships to correct the real-time temperature to obtain the correction temperature, and then the various correction temperatures are integrated to determine the ambient temperature of the physical space. The actual temperature of the physical space is more accurately represented by the ambient temperature. On the basis of the accurate ambient temperature, more accurate ice formation time and ice defrosting time can be obtained, thereby ensuring that the ice maker can stably, efficiently and accurately carry out multiple rounds of ice making and defrosting.

[0065] Based on any embodiment of the method of the present application, the mapping relationship between the real-time temperature measured by each temperature sensor and its error temperature relative to the actual ambient temperature at the time of measurement can be further determined with the help of this embodiment. Accordingly, referring to FIG5 , the real-time temperature deviation is corrected according to the compensation temperature corresponding to each real-time temperature. Before obtaining the correction temperature corresponding to each real-time temperature, the following steps are included:

[0066] Step S4100: Implement multiple rounds of ice making by the ice maker to obtain the corresponding real-time temperature of each temperature sensor of the ice maker under different actual ambient temperatures during each round of ice making;

[0067] One or more batches of ice-making machines are prepared, and each ice-making machine is used to perform multiple rounds of ice-making. When each ice-making machine is started for each round of ice-making, a temperature measuring device external to the ice-making machine reads the actual ambient temperature at that time, along with the real-time temperature measured by each temperature sensor of the ice-making machine at that time. The actual ambient temperature and the real-time temperature form a data pair.

[0068] Step S4200: determining a compensation temperature between each real-time temperature and its corresponding actual ambient temperature, wherein the compensation temperature corresponding to the real-time temperature measured by the temperature sensor during the first round of ice making is set to the average of the error temperatures between the real-time temperatures measured in the hot state and the cold state of the ice maker and its corresponding actual ambient temperature;

[0069] For each data pair, the actual ambient temperature is subtracted from the real-time temperature to obtain the error temperature between the two, which is also known as the compensation temperature. By determining the compensation temperature for each data pair one by one, we can further obtain data pairs between the real-time temperature and the compensation temperature.

[0070] Considering that it's impossible to determine in advance whether the ice maker is in the hot or cold state before actually starting its first ice-making cycle, and the compensation temperatures in the hot and cold states differ, a data pair corresponding to the first ice-making cycle can be provided. Based on this, the ice maker can be controlled to start the first ice-making cycle in the hot and cold states, respectively, based on the same real-time temperature, to determine the corresponding real-time temperature and compensation temperature. The compensation temperature in the hot state and the compensation temperature in the cold state are then summed and averaged, and this average is combined with the real-time temperature to form a data pair. This process prevents outliers in the data pair corresponding to the first ice-making cycle, and subsequent data fitting ensures that the fitted formula more accurately reflects the mapping relationship between the real-time temperature of the temperature sensor and the compensation temperature.

[0071] Step S4300: Perform data fitting based on the corresponding relationship between the real-time temperature and the compensation temperature to obtain a temperature compensation relationship formula corresponding to each temperature sensor, so as to determine the corresponding compensation temperature according to the real-time temperature collected by the temperature sensor.

[0072] In addition to determining the data pairs of each real-time temperature and the compensated temperature, data fitting can be performed based on these data pairs to fit the mapping relationship between the real-time temperature and the compensated temperature. It is not difficult to understand that there is a linear relationship between the real-time temperature and the compensated temperature, and thus a corresponding temperature compensation relationship formula can be obtained. Through this temperature compensation relationship formula, the corresponding compensation temperature can be determined for a given real-time temperature.

[0073] According to the above embodiments, the mapping relationship between the real-time temperature measured by each temperature sensor of the ice maker and its compensation temperature can be determined in advance. After fitting the mapping relationship into a temperature compensation relationship formula, it is convenient to subsequently determine the corresponding compensation temperature based on the real-time temperature actually measured by the temperature sensor. Because before determining the mapping relationship, the data corresponding to whether the ice maker is in a hot state or a cold state before the first round of ice making is forcibly set, it can be ensured that the temperature compensation relationship formula after data fitting can more accurately reflect the linear relationship between the real-time temperature of the temperature sensor and its compensation temperature. Therefore, the compensation temperature determined in this way is more accurate and can provide a reliable basis for subsequent calculations.

[0074] Based on any embodiment of the method of the present application, referring to FIG6 , determining the ice formation time corresponding to the ambient temperature according to the first mapping relationship includes:

[0075] Step S5210: determining a ratio between an offset range of the ambient temperature relative to a temperature range defined by the temperature interval to which the ambient temperature belongs and the temperature range;

[0076] The first mapping relationship between the ambient temperature and its corresponding ice formation time can be constructed in advance. In this embodiment, the temperature is divided into zones to implement the constraint on the mapping relationship between the ambient temperature in different temperature intervals and its corresponding ice formation time. Accordingly, when the ambient temperature of the ice maker is determined, the temperature interval to which the ambient temperature, such as 25 degrees Celsius, belongs is first queried according to the various pre-divided temperature intervals, such as 23 to 28 degrees Celsius. The temperature interval actually defines a temperature range. For example, there is a temperature range of 5 degrees Celsius between 23 and 28 degrees Celsius. Then, based on the minimum temperature end value of the temperature interval, such as 23 degrees in the example, the difference between the ambient temperature and the minimum temperature end value can be calculated as 2 degrees Celsius, as the offset range of the ambient temperature relative to the temperature range defined by the temperature interval to which it belongs. Then, the offset range is divided by the temperature range to obtain the corresponding proportional value as the range ratio.

[0077] Step S5220: determining the time difference between the ideal ice formation time corresponding to the two temperature end values ​​of the temperature range, and multiplying the time difference by the travel ratio to obtain the ice formation time increment;

[0078] The two temperature endpoints of the temperature range, referred to as the maximum and minimum temperature endpoints, have corresponding ideal ice-forming times pre-determined. This ideal ice-forming time can be an empirical or experimental value and can be set so that when ice making is continued at the corresponding temperature endpoints and stops at the theoretical ice-forming time, the liquid in the ice mold has just completely frozen into ice cubes. The mapping relationship between the temperature endpoints and the ideal ice-forming time can be stored in a mapping table. Thus, by pre-determining the ideal ice-forming time corresponding to a number of temperature endpoints, the corresponding ice-forming time can be determined for any given ambient temperature in this embodiment.

[0079] Obtain the ideal ice-forming time corresponding to the maximum and minimum temperature ends of the temperature range, and calculate the absolute difference between the two to obtain a time difference as the ice-forming time distance. Furthermore, multiply the travel proportion calculated in the previous step by the ice-forming time distance to obtain the ice-forming time increment.

[0080] Step S5230: superimpose the ideal ice formation time corresponding to the minimum temperature end value of the two temperature end values ​​with the ice formation time increment to obtain a tentative ice formation time;

[0081] The physical quantity corresponding to the ice formation time increment determined above is the time span allocated to the ice formation time distance between the two temperature extremes of the temperature range to which the ambient temperature belongs. This time span is also the time difference required to extend the ideal ice formation time corresponding to the minimum temperature extreme of the temperature range when the wheel ice-making operation reaches the ice formation state under a given ambient temperature. Based on this, simply add the ideal ice formation time corresponding to the minimum temperature extreme of the temperature range to the ice formation time increment to obtain a sum, which can be used to calculate the ice formation time.

[0082] Step S5240: Determine the ice-forming time corresponding to the ice-making mold according to the calculated ice-forming time.

[0083] The preliminarily determined calculated ice formation time can generally be directly used as the ice formation time corresponding to the ambient temperature. In some embodiments, it can also be further verified and confirmed before deciding whether to use it as the ice formation time corresponding to the ambient temperature.

[0084] It can be seen that the relationship between the temperature end values ​​used to define each temperature interval and its ideal ice-forming time is linear, the relationship between the ambient temperature and its travel ratio is also linear, and the relationship between the travel ratio and the ice-forming time increment is also linear. Based on this, a given ambient temperature must ultimately have a unique ice-forming time corresponding to it, and this corresponding relationship constitutes the second mapping relationship.

[0085] According to the above embodiments, temperature zones are used for temperature zoning, and the ice formation time increment of the ice formation time distance of the ambient temperature relative to the temperature interval is determined according to the proportion of the offset distance of the ambient temperature from the minimum temperature end value in the temperature interval to which it belongs relative to the temperature distance defined by the two temperature end values ​​of the temperature interval. The ice formation time increment is then superimposed with the ideal ice formation time of the minimum temperature end value to determine the ice formation time corresponding to the ambient temperature. The particle size is extremely fine, and the obtained ice formation time is more accurate, which can ensure that when it is applied to the ice making operation control of the heat exchange mechanism, the ice formation can be accurately controlled.

[0086] Based on any embodiment of the method of the present application, referring to FIG. 7 , determining the ice-forming time corresponding to the ice-making mold according to the calculated ice-forming time includes:

[0087] Step S5241: determining whether the calculated ice formation time reaches the minimum continuous ice formation time corresponding to the ambient temperature;

[0088] As disclosed in the previous embodiment, generally, when the tentatively calculated ice formation time corresponding to the ambient temperature is determined based on the second mapping relationship, in most scenarios the tentatively calculated ice formation time can be used directly as the ice formation time corresponding to the ambient temperature. However, to further enhance the robustness of the ice making process and prevent inaccurate ice formation time due to other anomalies, the tentatively calculated ice formation time can be further verified. Accordingly, a determination is first made as to whether the tentatively calculated ice formation time has reached the minimum continuous ice formation time corresponding to the measured ambient temperature.

[0089] The minimum continuous ice time and ambient temperature also form a linear relationship. Similarly, a mapping relationship can be pre-set and constructed, referred to as a third mapping relationship. The corresponding data between the minimum continuous ice time and the actual ambient temperature can be stored in a mapping table, or the linear relationship between the two can be implemented as a mathematical formula. Based on this, when determining the minimum continuous ice time corresponding to the ambient temperature, a table lookup or mathematical calculation can be performed.

[0090] As mentioned above, the minimum ice-making time can be measured from the moment the ice-making starts in each ice-making round, until the ice cubes in the ice-making mold are formed, and then until some of the ice cubes are first connected to the corresponding moment. It can usually be slightly earlier than this moment by 1-3 seconds. The time length obtained in this way can be regarded as the minimum ice-making time.

[0091] Step S5242: When the tentatively calculated ice-forming time reaches the minimum continuous ice-forming time, the tentatively calculated ice-forming time is set as the ice-forming time corresponding to the ice-making mold;

[0092] When the calculated ice-forming time determined according to the ambient temperature reaches the minimum continuous ice-forming time corresponding to the ambient temperature, it usually indicates that there is an abnormality in the ice-forming time. In this case, in order to ensure the stability of the ice-making machine, the ice-forming time corresponding to the ambient temperature can be replaced with the minimum continuous ice-forming time corresponding to the ambient temperature, that is, the minimum continuous ice-forming time is used as the actual ice-forming time, and the heat exchange mechanism is controlled to continue to implement the ice-making work according to the minimum continuous ice-forming time. This can ensure that the ice-making can still complete the formation of ice cubes smoothly, and the ice cubes generally will not be connected, or even if there is a slight connection, it is easier to de-ice and demold. It can be seen that the minimum continuous time can play an effective safety net.

[0093] Step S5243: When the calculated ice-forming time does not reach the minimum continuous ice-forming time, the minimum continuous ice-forming time is set as the ice-forming time corresponding to the ice-making mold.

[0094] When the calculated ice-forming time determined based on the ambient temperature does not reach the minimum continuous ice-forming time corresponding to the ambient temperature, it indicates that the determined ice-forming time is relatively reliable. At this time, the ice-forming time can be verified and the heat exchange mechanism can be controlled to continue making ice according to the directly determined ice-forming time.

[0095] According to the above embodiments, it can be known that with the help of the mapping relationship between the ambient temperature and the minimum continuous ice time, the minimum continuous ice time corresponding to the ambient temperature is used to verify the ice formation time determined according to the ambient temperature. When the ice formation time reaches or exceeds the minimum continuous ice time, the minimum continuous ice time is used as the actual ice formation time, replacing the former to control the heat exchange mechanism to implement refrigeration. When the ice formation time does not reach the minimum continuous ice time, it indicates that the determined ice formation time is more reliable and has passed the verification. The heat exchange mechanism can be controlled to implement refrigeration according to the ice formation time. It can be seen from this that the minimum continuous ice time can provide a basis for the reliability verification of the ice formation time, and can provide a backup data when the ice formation time is abnormal, which can ensure that the refrigerator is more robust when implementing refrigeration, and can ensure that each ice-making round can successfully complete the formation of ice cubes.

[0096] Based on any embodiment of the method of the present application, before determining the ice formation time corresponding to the ice-making mold according to the calculated ice formation time, the method includes:

[0097] Step S3100: collecting the time taken for multiple ice molds in the ice mold to reach a connected and frozen state when the ice maker makes ice at multiple ambient temperatures, as the continuous freezing time at the corresponding ambient temperatures;

[0098] The mapping relationship between ambient temperature and minimum continuous freezing time can be constructed in advance. In this embodiment, one or more ice makers are used in advance, each of which is used to perform multiple rounds of ice making. The actual ambient temperature at the start of ice making is determined. Then, the time elapsed from the start of each round of ice making to the moment when ice cubes in some of the ice molds become connected and frozen is determined. This time is used as the continuous freezing time corresponding to the actual ambient temperature. The actual ambient temperature and the continuous freezing time form a data pair. By performing multiple rounds of ice making on multiple refrigerators, a large number of data pairs can be obtained.

[0099] Step S3200: performing data fitting based on the corresponding relationship between the ambient temperature and the corresponding continuous freezing time to determine a continuous freezing time formula, so as to determine the continuous freezing time corresponding to the ambient temperature as the minimum continuous freezing time.

[0100] By mapping the actual ambient temperature and continuous freezing time from each data pair into a coordinate system to obtain individual coordinate points, and performing data fitting on these coordinate points, a continuous freezing time formula can be determined. This continuous freezing time formula also describes the mapping relationship between ambient temperature and continuous freezing time, also known as the third mapping relationship. Subsequently, when a given ambient temperature is substituted into the continuous freezing time formula, the corresponding continuous freezing time is calculated, which can be used as the minimum continuous freezing time for that ambient temperature.

[0101] According to the above embodiments, it can be seen that by fitting the mathematical formula between the ambient temperature and the minimum ice-forming time, it is very convenient to subsequently determine the corresponding minimum ice-forming time according to the ambient temperature. It can be realized as a computer program for automatic calculation, which can improve the intelligence level of the verification decision on the ice-forming time.

[0102] Based on any embodiment of the method of the present application, determining the deicing time corresponding to the ambient temperature according to the second mapping relationship includes:

[0103] Step S5310: Determine a mapping value of the temperature range to which the ambient temperature belongs;

[0104] As previously mentioned, a second mapping relationship exists between ambient temperature and the ice maker's defrosting time. Typically, when multiple temperature intervals are set, the lowest temperature interval is used as the basis. As the temperature increases, the corresponding defrosting time decreases. This relationship changes in a gradient. Based on this pattern, the defrosting times corresponding to different actual ambient temperatures can be pre-collected, and the actual ambient temperatures and their corresponding defrosting times can be combined to form data pairs. Furthermore, considering the need to combine this pattern and reduce computational complexity, each temperature interval can be sequentially mapped into ordered numerical values. Based on the actual ambient temperature, the corresponding mapping value for the temperature interval to which it belongs is determined. This mapping value replaces the corresponding actual ambient temperature in the data pair, thereby obtaining a data pair of the temperature interval mapping value and the defrosting time. By fitting multiple such data pairs, a mathematical formula can be obtained that can be used as a demolding attenuation formula.

[0105] Accordingly, when the ice maker determines its corresponding ambient temperature, the temperature range to which it belongs can be determined according to the ambient temperature, and then the mapping value corresponding to the temperature range can be determined.

[0106] Step S5320: Determine the defrosting time corresponding to the mapped value according to a preset defrosting attenuation formula, wherein the defrosting attenuation formula stipulates that the higher the temperature represented by the temperature interval, the shorter the defrosting time determined according to the mapped value of the temperature interval.

[0107] Substituting the mapped value determined based on the ambient temperature into the deicing attenuation formula, we can calculate the corresponding deicing time. Based on the construction principle of the deicing attenuation formula, it is not difficult to understand that the higher the temperature range represented by the ambient temperature, the shorter the corresponding deicing time, which is consistent with the actual law.

[0108] According to the above embodiments, it can be seen that the second mapping relationship between the ambient temperature and its corresponding defrosting time can also be fitted into a mathematical formula. When the ice maker is working, when the ambient temperature is determined, the corresponding defrosting time can be quickly determined according to the mathematical formula. Therefore, the heat exchange mechanism can be controlled according to the defrosting time to successfully complete the defrosting, and further the demoulding can be implemented. The whole process can be realized automatically, which greatly improves the intelligence level of the ice maker.
