[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0036] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0037] Figure 1 This is a flowchart illustrating a refrigerator control method according to an exemplary embodiment, such as... Figure 1 As shown, this refrigerator control method can be used in a refrigerator and includes the following steps.

[0038] S101, obtain the first operating cost of the refrigerator under different control paths.

[0039] The control path includes control parameters for controlling the refrigerator at different time periods. These control parameters are used to control the refrigerator's operating power. The control path includes any one of the first control path, the second control path, and the third control path.

[0040] For the first control path, the refrigerator's cooling speed can reach a first speed, and the refrigerator's cooling speed reaching the first speed indicates that the refrigerator's cooling speed is relatively fast. For example, the first control path includes at least one of the following control parameters: (1) the refrigerator's power change rate can reach a first preset rate; (2) the refrigerator's minimum operating time is greater than a first preset time; (3) the refrigerator's cooling temperature overshoot allowable range is within a preset temperature range, where the cooling temperature overshoot allowable range refers to the temperature value that the refrigerator can exceed after reaching the target temperature.

[0041]

[0042] Table 1 Referring to Table 1, under the first control path, the power change rate of the refrigerator compressor can be allowed to reach the first preset rate of 100%, indicating that the refrigerator compressor can operate at full power; and the minimum operating time of the refrigerator is controlled. The minimum operating time is 5 minutes to avoid the shortened lifespan of the compressor caused by frequent start-stop cycles, thus protecting the compressor. It also controls the refrigerator's temperature overshoot to within a preset range of 2°C, thereby ensuring rapid cooling. The first control path is suitable for rapid cooling in emergency situations or rapid temperature recovery in case of power grid anomalies. While it achieves rapid cooling, it results in greater wear and tear on the refrigerator compressor.

[0043] For the second control path, the refrigerator's cooling speed can reach the second speed. The refrigerator's cooling speed reaching the second speed indicates that the refrigerator's cooling speed is gradual, and the second speed is less than the first speed. For example, the second control path includes at least one of the following control parameters: (1) the refrigerator's power change rate is less than the second preset rate, and the second preset rate is less than the first preset rate; (2) the adjustment range of the refrigerator's cooling temperature is a preset range; (3) the interval duration for adjusting the cooling temperature is a second preset duration.

[0044]

[0045] Table 2 Referring to Table 2, under the second control path, the power change rate of the refrigerator compressor is less than or equal to the second preset rate of 10%, and the power change of the compressor is linear; the power adjustment increment of the refrigerator compressor is controlled at a preset increment of 5% each time; and the power adjustment interval of the refrigerator compressor is controlled at a second preset duration of 1 minute. The mode applicable to the second control path is the equipment aging mode, which can reduce the risk of equipment aging through smooth power adjustment and has better balance.

[0046] For the third control path, the power of the refrigerator changes according to a preset level, with different levels corresponding to different power levels, and the power difference between adjacent levels is equal. For example, the third control path includes at least one of the following control parameters: (1) the power of the refrigerator changes according to a preset step level; (2) the dwell time of each level is the third preset duration of the change; (3) the interval between adjustments between each level is longer than the fourth preset duration.

[0047]

[0048] Table 3 Referring to Table 3, the refrigerator's power can be adjusted according to the third control path. The levels gradually increase from 50% to 70% and then to 90%. In a cooling scenario after the refrigerator compressor starts, you can follow... The compressor's operating power is gradually adjusted in stages using increments of 50%, 70%, and 90%. The duration of each increment can vary from 5 to 10 minutes (a third preset time), ensuring power stability at each level before gradually moving to the next. Furthermore, the interval between each increment is longer than the fourth preset time (2 minutes), ensuring the refrigerator's internal cooling temperature stabilizes before gradually moving to the next level. This third control path is applicable to grid interaction mode or the preservation mode requiring precise temperature control, using increments to accurately regulate the refrigerator's cooling temperature at different levels.

[0049] The first operating cost refers to the operating cost incurred by the refrigerator under the control of different control paths. The operating cost varies depending on the control path. The first operating cost includes at least two of the following dimensions: energy consumption cost, equipment wear and tear cost, preservation cost, and grid interaction cost. The refrigerator's energy consumption cost characterizes the cost incurred in operating the refrigerator; the equipment wear and tear cost characterizes the cost incurred due to the aging and wear of equipment within the refrigerator, including the compressor, fan, and electronic components; the preservation mode includes the operating cost of maintaining the freshness of the stored items; and the grid interaction cost characterizes the operating cost of meeting grid demands, such as the need to reduce electricity consumption during peak hours.

[0050] Optionally, the refrigerator can be controlled to operate according to different control paths before it leaves the factory, thereby testing the initial operating cost of the refrigerator under different control paths.

[0051] S102, select the target operating cost that meets the preset conditions from the first operating costs of different control paths.

[0052] Among them, the target operating cost that meets the preset conditions includes any one of the following: selecting the minimum operating cost from the first operating costs of different control paths as the target operating cost, or selecting the first operating cost that is less than the preset cost from the first operating costs of different control paths as the target operating cost.

[0053] S103, the refrigerator is controlled by the target control path corresponding to the target operating cost.

[0054] Among them, the target control path is the path among the first control path, the second control path, and the third control path that can satisfy the operating cost reduction of at least two dimensions of energy consumption cost, equipment wear cost, preservation cost, and grid interaction cost.

[0055] It is understandable that when selecting the target control path corresponding to the target operating cost that meets the preset conditions, the target control path is obtained with the goal of reducing the first operating cost of the refrigerator.

[0056] For example, the first operating cost includes equipment wear and tear costs and preservation costs. When selecting the control path corresponding to the target operating cost that meets the preset conditions, the goal is to reduce the equipment wear and tear costs and preservation costs of the refrigerator, and then select the target control path that can reduce the equipment wear and tear costs and preservation costs.

[0057] For example, the first operating cost includes energy consumption cost, equipment wear and tear cost, preservation cost and grid interaction cost. When selecting the control path corresponding to the target operating cost that meets the preset conditions, the comprehensive goal is to reduce the refrigerator's energy consumption cost, equipment wear and tear cost, preservation cost and grid interaction cost. The target control path that can reduce energy consumption cost, equipment wear and tear cost, preservation cost and grid interaction cost is selected.

[0058] In related technologies, the control path of a refrigerator is selected based on a single dimension of operating cost. For example, the control path of a refrigerator is determined with the goal of minimizing the energy consumption cost of the refrigerator. However, this approach does not take into account the wear and tear of the refrigerator, the preservation of food, and the operating costs of the refrigerator in the power grid to meet the grid demand. As a result, after controlling the refrigerator to operate according to the control path, the refrigerator can only meet the single requirement of reducing operating costs, but cannot meet other operating requirements such as reducing wear and tear of the refrigerator, improving food preservation capabilities, and meeting the grid demand. Its overall operating effect is poor.

[0059] The above technical solution aims to optimize the refrigerator's operating costs in at least two of the following dimensions: energy consumption cost, equipment wear and tear cost, preservation cost, and grid interaction cost. This will lead to a target control path for the refrigerator. Only by using this target control path to control the refrigerator's operation can the operating costs in at least two of these dimensions be optimized, resulting in a better overall operating performance for the refrigerator.

[0060] Figure 2 and Figure 3 This is an exemplary embodiment of the present disclosure, which is an exemplary scheme for interpreting the calculation of energy consumption costs, including the following steps: S104, obtain the real-time electricity cost and the real-time operating power of the refrigerator.

[0061] Among them, the real-time electricity cost can be the real-time electricity price of the power grid currently used by the refrigerator. The real-time electricity price of the power grid can be determined by factors such as the region where the power grid is located and the time period of electricity consumption during the day.

[0062] The real-time operating power of the refrigerator refers to the real-time operating power of the compressor inside the refrigerator.

[0063] S105, the energy consumption cost is obtained based on the real-time electricity cost and the real-time operating power.

[0064] Among them, the energy cost of a refrigerator is used to characterize the cost consumed by the refrigerator to cool the stored items.

[0065] Optionally, the real-time electricity cost of the refrigerator at each point in time within a preset time period before it leaves the factory can be multiplied by the real-time operating power to obtain the total electricity cost of the refrigerator within that preset time period. This total electricity cost is the energy consumption cost of the refrigerator, and its calculation formula is as follows: (1) In formula (1), It's the cost of energy consumption. It is the real-time electricity cost, which is also the electricity cost detected during the refrigerator's testing process before it leaves the factory. The unit is KW. This is the real-time operating power, which is also the operating power detected during the refrigerator's testing before it leaves the factory. The unit is yuan / kWh. It is the duration of the preset time period.

[0066] It is understandable that, as can be seen from formula (1), energy consumption cost is positively correlated with real-time operating power, and energy consumption cost is also positively correlated with real-time electricity cost.

[0067] By using the above technical solution, after obtaining the target control path for the refrigerator by reducing its energy consumption cost, the refrigerator's operation can be controlled using the obtained target control path, thereby reducing the refrigerator's operating cost.

[0068] Figure 4 and Figure 5 This is an exemplary embodiment of the present disclosure, which provides an exemplary scheme for interpreting the calculation of device wear and tear costs, including the following steps: S106, obtain the wear and tear costs of multiple different types of components in the refrigerator.

[0069] Among them, the various types of devices include compressors, fans and electronic components, and the aging costs of these various types of devices include compressor wear costs, fan wear costs and electronic component wear costs.

[0070] For compressor wear cost, it characterizes the compressor lifespan lost during operation. The lower the compressor wear cost, the less compressor lifespan is reduced. Compressor wear cost can be obtained based on at least one of the following: compressor start-up wear cost, compressor operation wear cost, compressor frequency variation wear cost, and load deviation cost. Specifically, compressor start-up wear cost characterizes the compressor lifespan lost during startup; compressor operation wear cost characterizes the compressor lifespan lost during operation; compressor frequency variation wear cost characterizes the compressor lifespan lost when the compressor frequency variation rate exceeds a preset rate; and load deviation cost characterizes the compressor lifespan lost when the real-time operating power deviates from the target operating power. The compressor wear cost can be calculated using the following formula: (2) In formula (2), It is the cost of compressor wear and tear; It is the cost of compressor start-up wear. This represents the number of times the compressor has been started. This represents the wear and tear cost associated with each compressor start-up. It is the cost of compressor operation and wear. It is the coefficient of wear and tear, which is a constant. It is the real-time operating power of the compressor. This represents the compressor's operating time; It is the wear and tear cost due to compressor frequency variations. It is the wear coefficient due to frequency variation, and it is a constant. It is the absolute value of the rate of change of the compressor frequency; The load deviates from the cost. It is the load deviation wear coefficient, which is a constant. The real-time operating power of the compressor. It is the target operating power of the compressor. The target operating power is the operating power calculated based on the overall operating status of the compressor. This operating power is related to the refrigerator's energy consumption, cooling efficiency, cooling capacity, and other data.

[0071] As can be seen from the above formula (2), the compressor wear cost can be obtained by adding at least one of the following: compressor start-up wear cost, compressor operation wear cost, compressor frequency change wear cost, and load deviation cost. Furthermore, at least one of these factors is positively correlated with the compressor wear cost, and the compressor wear cost is positively correlated with the equipment wear cost. Therefore, when selecting a target control path to reduce equipment wear cost, the target control path is essentially selected with the goal of reducing at least one of these factors.

[0072] For fan wear costs, the wear cost characterizes the fan life consumed during operation. The lower the fan wear cost, the less fan life is lost. Fan wear costs can be obtained from at least one of the following: fan operation wear cost and fan speed change wear cost. The fan operation wear cost characterizes the fan life consumed during operation; the fan speed change wear cost characterizes the fan life consumed by the number of speed changes. The fan wear cost can be calculated using the following formula: (3) In formula (3), It is the cost of wind turbine wear and tear; It is the cost of wear and tear during wind turbine operation. It is the cost of wear and tear on the fan per unit time. It refers to the operating time of the fan; It's the cost of the fan speed change. It is the cost of a single speed change of the wind turbine. It refers to the number of times the fan changes speed.

[0073] As can be seen from the above formula (3), the wind turbine wear cost can be obtained by adding at least one of the wind turbine operating wear cost and the wind turbine speed change cost. Moreover, at least one of the wind turbine operating wear cost and the wind turbine speed change cost is positively correlated with the wind turbine wear cost, and the wind turbine wear cost is positively correlated with the equipment wear cost. Therefore, when selecting the target control path to reduce the equipment wear cost, the target control path is essentially selected with the goal of reducing at least one of the wind turbine operating wear cost and the wind turbine speed change cost.

[0074] For electronic component wear cost, electronic components refer to all components in a refrigerator except the compressor and fan. Electronic component wear cost characterizes the lifespan of an electronic component during operation; the lower the wear cost, the less lifespan is lost. Electronic component wear cost can be obtained based on at least one of the following: temperature wear cost and power thermal shock wear cost. Temperature wear cost characterizes the lifespan lost due to overheating; power thermal shock wear cost characterizes the lifespan lost due to temperature fluctuations. The electronic component wear cost can be obtained using the following formula: (4) In formula (4), It is the cost of wear and tear on electronic components; It is the cost of temperature wear and tear on electronic components. It is the component cost of electronic components. It refers to the temperature sensitivity of electronic components. It is Boltzmann's constant. It can refer to the temperature of an electronic component, or specifically the junction temperature of that component. The junction temperature refers to the temperature of the semiconductor PN junction inside the electronic component. It is the rated temperature of electronic components. It is the rated lifespan of electronic components; It is the cost of power thermal shock wear of electronic components. It is the wear and tear cost of an electronic component per power cycle, and it is a constant. It is the number of power cycles of an electronic component.

[0075] As can be seen from the above formula (4), the wear cost of electronic components can be obtained by adding at least one of the temperature wear cost and the power thermal shock wear cost. The idea expressed by formula (4) is that the lifespan of electronic components decreases by a certain amount for every increase in temperature. Each power cycle of electronic components will generate thermal stress on the bonding wires and solder layers of the IGBT (Insulated Gate Bipolar Transistor) in the electronic components, accelerating aging. Furthermore, at least one of the temperature wear cost and the power thermal shock wear cost is positively correlated with the wear cost of electronic components, and the wear cost of electronic components is positively correlated with the wear cost of equipment. When selecting the target control path to reduce the wear cost of equipment, it is essentially to select the target control path by reducing at least one of the temperature wear cost and the power thermal shock wear cost of sub-components.

[0076] S107, the wear cost of the device is obtained based on the wear cost of multiple different types of devices.

[0077] Among them, equipment wear cost is used to characterize the equipment life consumed during the use of the refrigerator. The lower the equipment wear cost, the less equipment life is consumed.

[0078] Alternatively, the wear costs of different types of components can be added together to obtain the equipment wear cost. For example, the wear costs of compressors, fans, and electronic components can be added together to obtain the equipment wear cost.

[0079] Alternatively, the wear costs of different types of devices can be weighted together with their respective weights to obtain the equipment wear cost, and the calculation formula is as follows: (5) In formula (5), It is the cost of equipment wear and tear; It is the cost of compressor wear and tear. This is the weight corresponding to the compressor wear cost; It is the cost of wind turbine wear and tear. This is the weight corresponding to the wear and tear cost of the wind turbine; It is the cost of wear and tear on electronic components. It is the weight corresponding to the wear and tear cost of electronic components.

[0080] By using the above technical solution, after obtaining the target control path of the refrigerator to reduce the equipment wear and tear costs, the refrigerator operation can be controlled by using the obtained target control path, thereby reducing the equipment wear and tear costs of the refrigerator.

[0081] Firstly, combining the above formulas (2) and (5), it can be seen that the equipment wear cost is positively correlated with the compressor wear cost. Therefore, after the equipment wear cost is reduced, the compressor wear cost can also be reduced, thereby extending the service life of the compressor.

[0082] Secondly, combining the above formulas (3) and (5), it can be seen that the equipment wear cost is positively correlated with the fan wear cost. Therefore, after the equipment wear cost is reduced, the fan wear cost can also be reduced, thereby extending the service life of the fan.

[0083] Secondly, combining the above formulas (4) and (5), it can be seen that the wear cost of equipment is positively correlated with the wear cost of electronic components. Therefore, after the wear cost of equipment is reduced, the wear cost of electronic components can also be reduced, thereby extending the service life of electronic components.

[0084] Figure 6 and Figure 7 This is an exemplary embodiment of the present disclosure, which illustrates an exemplary scheme for calculating preservation costs, including the following steps: S108, Obtain the item parameters of the items stored in the refrigerator.

[0085] Among them, the item parameters are used to characterize the attribute information of the stored item, which can be food, skin care products, medical supplies, etc. stored in the refrigerator.

[0086] The item parameters include the type and quantity of the stored items, the volume of the stored items, the item cost of the stored items, and the temperature sensitivity parameters of the stored items.

[0087] The number of types of stored items includes the number of different types of stored items. For example, pork, vegetables, and beverages are different types of stored items, as are pork, skincare products, and medical supplies. It's understandable that the more types of stored items there are, the higher the refrigeration operating costs for the refrigerator.

[0088] The volume of the stored item is used to characterize its size. It can be understood that the larger the volume of the stored item, the higher the refrigeration operating cost for the refrigerator.

[0089] The cost of stored items is used to characterize their value, which can be determined by their market value. It can be understood that the higher the cost of stored items, the higher their value; therefore, the refrigerator's operating cost to maintain the cooling system for those items should also be higher, thus ensuring the quality of high-value stored items.

[0090] Temperature sensitivity parameters are used to characterize the sensitivity of stored items to temperature. Different types of stored items have different temperature sensitivities. For example, the temperature sensitivity parameters for ice cream or frozen meat are in the range of [0.15, 0.2], the temperature sensitivity parameters for seafood or fresh meat are in the range of [0.1, 0.15], the temperature sensitivity parameters for vegetables or fruits are in the range of [0.05, 0.1], and the temperature sensitivity parameters for beverages or condiments are in the range of [0.02, 0.05].

[0091] S109, Based on the item parameters, obtain the preservation cost.

[0092] Among them, preservation cost is used to characterize the operating cost of a refrigerator in order to ensure the quality (such as freshness) of stored items.

[0093] Alternatively, the preservation cost can be determined based on the item's parameters and the temperature fluctuation range inside the refrigerator.

[0094] For example, see Figure 7 As shown, the preservation cost can be obtained based on the type and quantity of stored items, the volume of stored items, the cost of the stored items, the temperature-sensitive parameters of the stored items, and the temperature fluctuation range. The calculation formula is as follows: (6) In formula (6), It's the cost of preservation. It refers to the types and quantities of stored items. It is the volume of the i-th type of storage. It is the item cost of the i-th type of storage. It is the temperature-sensitive parameter of the i-th type of storage. It refers to the temperature fluctuation range inside the refrigerator.

[0095] As can be seen from formula (6), for each of the multiple storage items, the preservation cost of the storage item can be obtained first based on the storage item's volume, item cost, temperature sensitive parameters, and temperature fluctuation range; then the preservation cost of the refrigerator can be obtained by accumulating the preservation costs of multiple storage items.

[0096] By using the above technical solution, after obtaining the target control path of the refrigerator to reduce the preservation cost, the refrigerator operation can be controlled by using the obtained target control path. This can reduce the preservation cost of the refrigerator, and can also be regarded as reducing the operating cost consumed by the refrigerator to ensure the quality of the stored items while ensuring the quality of the stored items.

[0097] Figure 8 and Figure 9 This is an exemplary embodiment of the present disclosure, which is used to interpret an exemplary scheme for calculating grid interaction costs, including the following steps: S110, obtain the real-time electricity cost, electricity demand cost and preservation loss cost of the refrigerator.

[0098] Among them, the real-time electricity cost of the refrigerator is used to characterize the current electricity cost of the refrigerator in the power grid, and the electricity cost is different in different time periods. The real-time electricity cost is higher in the time period with greater electricity demand.

[0099]

[0100] Table 4 As shown in Table 4, the electricity consumption time of refrigerators within the power grid can be divided into off-peak periods, neutral periods, and peak periods. The off-peak period ranges from 0:00 to 6:00, with a real-time electricity cost of 0.3; the neutral period ranges from 6:00 to 18:00 and from 22:00 to 24:00, with a real-time electricity cost of 0.6; and the peak period ranges from 19:00 to 22:00, with a real-time electricity cost of 1.2. Table 4 shows that the real-time electricity cost gradually decreases from peak to off-peak periods.

[0101] It is understandable that real-time electricity cost is used as one of the parameters for calculating the grid interaction cost of the refrigerator. When the real-time electricity cost changes with the time of electricity use, the grid interaction cost will also change with the real-time electricity cost. This makes the grid interaction cost of the refrigerator in the grid different with different time periods of electricity use, and the obtained grid interaction cost is closer to the actual electricity consumption of the grid.

[0102] Among them, the electricity demand cost is used to characterize the reward value of the refrigerator after making power adjustments to meet the grid demand. Different grid demands exist at different times, and the refrigerator has different operating power under different grid demands. As the electricity demand in the grid increases, the operating power of the refrigerator will decrease.

[0103] Alternatively, the electricity demand cost can be obtained based on the power reduction of the refrigerator to meet grid demand and the bonus value after the refrigerator makes power adjustments to meet grid demand.

[0104] For example, the cumulative value of the product between the power change of the refrigerator in response to grid demand and the bonus value of the refrigerator's power adjustment in response to grid demand can be used as the cost of electricity demand. The formula is as follows: (7) In formula (7), It is the cost of electricity demand; It is the power that the refrigerator changes in response to the demand of the power grid; It is the bonus value after the refrigerator adjusts its power output in response to the grid's demands.

[0105]

[0106] Table 5 As shown in Table 5, the types of grid demand include peak shaving response demand, valley filling response demand, and emergency response demand. The reward value that a refrigerator receives for responding to grid demand varies under different grid demand types.

[0107] The peak shaving response demand indicator shows that the grid load is greater than 90% of the first preset load value, and the power demand of other devices in the grid is high during peak electricity consumption. At this time, the refrigerator power needs to be reduced (for example, by 30% to 50%) to meet the peak shaving response demand, and the reward value provided is 2. Furthermore, reducing the refrigerator power when the grid load is greater than 90% during peak electricity consumption can reduce the real-time electricity cost of the refrigerator.

[0108] The valley-filling response demand indicator indicates that the grid load is less than 10% of the second preset load value, and the electricity demand of other devices in the grid is low, falling during the off-peak period. At this time, the refrigerator power can be increased (e.g., by 20%~30%) to meet the valley-filling response demand, providing a reward value of 1. The second preset load value is less than the first preset load value. Furthermore, when the grid load is less than 10% and during the off-peak period, increasing the refrigerator power allows for greater cooling capacity during periods of lower real-time electricity costs, storing more cooling capacity for backup during peak electricity demand periods.

[0109] An emergency response indicates a power grid anomaly. In this case, the refrigerator can be controlled to quickly shut down or reduce its load, with a reward value of 5. A power grid anomaly refers to the refrigerator receiving a power grid anomaly signal from the server. The refrigerator is one of many refrigerators in a cluster. When more than a preset number of refrigerators in the cluster experience anomalies, the current refrigerator will receive the power grid anomaly signal from the server, thus quickly shutting down or reducing its load.

[0110] It is understandable that electricity demand cost is used as one of the calculation parameters for grid interaction cost. When electricity demand cost changes, that is, when the reward value that the refrigerator receives for responding to grid demand changes, the grid interaction cost for users to participate in the grid will also change.

[0111] Among them, the preservation loss cost is used to characterize the degree of quality loss of stored items caused by the refrigerator making power adjustments to meet the grid demand.

[0112] Alternatively, the degree of quality loss of the stored items can be determined based on the cost of the stored items and the temperature fluctuation range inside the refrigerator.

[0113] For example, the product of the quality loss coefficient of the stored item, the cost of the stored item, and the temperature fluctuation range inside the refrigerator can be used as the degree of quality loss of the stored item. The calculation formula is as follows: (8) In formula (8), It is the cost of food preservation losses; It is the quality loss coefficient of the stored items; It refers to the temperature fluctuation range inside the refrigerator; It is the cost of the stored items.

[0114] It is understandable to include the cost of food preservation loss as one of the calculation parameters for the refrigerator's grid interaction cost. Since the refrigerator will change its operating power in response to grid demand, the change in operating power may also cause a certain loss in the quality of the stored food in the refrigerator. Therefore, the cost of food preservation loss caused by the change in operating power needs to be included as one of the costs of participating in the grid.

[0115] S111, the grid interaction cost is obtained based on the real-time electricity cost, the electricity demand cost, and the preservation loss cost.

[0116] Alternatively, the difference between the electricity demand cost and the preservation loss cost can be subtracted from the real-time electricity cost to obtain the grid interaction cost, and the calculation formula is as follows: (9) In formula (9), It is the cost of grid interaction. It is the real-time cost of electricity. It is the cost of electricity demand. It's the cost of preservation losses.

[0117] It's understandable that the value of subtracting the preservation loss cost from the electricity demand cost is essentially the reward value of the refrigerator adjusting its power to meet grid demand minus the loss value after adjusting the refrigerator's power. The final result is the actual reward value brought by the refrigerator meeting grid demand. If this reward value is positive, it means that the power adjustment by the refrigerator to meet grid demand brings additional gains; conversely, if the reward value is negative, it means that the power adjustment by the refrigerator to meet grid demand brings negative benefits. Based on this, subtracting the actual reward value brought by the refrigerator meeting grid demand from the real-time electricity cost yields the actual cost of the refrigerator participating in grid operations. This grid interaction cost is more consistent with the power adjustment mechanism the refrigerator makes in response to different types of grid demand.

[0118] By employing the aforementioned technical solution, after obtaining the target control path for the refrigerator by reducing its grid interaction costs, and then using this target control path to control the refrigerator's operation, the grid interaction costs can be further reduced. Firstly, grid interaction costs are inversely proportional to electricity demand costs. When grid interaction costs decrease, electricity demand costs increase, meaning the refrigerator needs to adjust its operating power to better meet grid demands. Secondly, grid interaction costs are directly proportional to preservation loss costs. When grid interaction costs decrease, preservation loss costs decrease, meaning the refrigerator will experience less preservation loss in meeting grid demands, thus better protecting the quality of stored food.

[0119] Figure 10 This is an exemplary embodiment involving step S102 above, which is used to interpret an exemplary embodiment of obtaining the target operating cost by filtering out the weight combinations corresponding to different operating modes of the refrigerator, including the following steps: S102-1, Obtain the weight combination corresponding to the operating mode of the refrigerator.

[0120] The refrigerator's operating mode determines the different weight combinations of the operating costs in various dimensions of the first operating cost. The different weights in these combinations represent the relative importance of the operating costs in different dimensions of the first operating cost. The operating modes include: a first operating mode, a second operating mode, a third operating mode, a fourth operating mode, and a fifth operating mode.

[0121] The first operating mode can be the economic mode, which focuses on saving electricity and grid cost benefits. Under the first operating mode, the energy consumption cost of the refrigerator can be reduced to a greater extent.

[0122] The second operating mode can be the lifespan mode, which mainly protects the various components inside the refrigerator. In the second operating mode, the wear and tear costs of the equipment can be reduced to a greater extent, and the lifespan of the equipment can be slowed down.

[0123] The third operating mode can be the preservation mode, which mainly focuses on protecting the freshness of the food stored in the refrigerator. In the third operating mode, the preservation cost can be reduced to a greater extent. The lower the preservation cost, the lower the operating cost of ensuring the freshness of the stored food.

[0124] The fourth operating mode can be the grid mode, which mainly focuses on responding to grid demand. Under the fourth operating mode, the grid interaction cost can be reduced to a greater extent. The lower the grid interaction cost, the lower the operating cost of the refrigerator's actions to meet grid demand.

[0125] The fifth operating mode can be a balanced mode, which is balanced in terms of various operating costs such as energy consumption cost, equipment wear and tear cost, preservation cost and grid interaction cost.

[0126]

[0127] Table 6 As can be seen from Table 6, in the first operating mode, the weights of energy consumption cost, equipment wear and tear cost, preservation cost, and grid interaction cost are 0.4, 0.2, 0.1, and 0.3, respectively. Energy consumption cost has a larger weight, so it can focus more on reducing the energy consumption cost of the refrigerator.

[0128] In the second operating mode, the weighting combination of energy consumption cost, equipment wear and tear cost, preservation cost, and grid interaction cost is 0.2, 0.5, 0.1, and 0.2, respectively. The weighting of equipment wear and tear cost is larger, so it can focus more on reducing the equipment wear and tear cost of the refrigerator.

[0129] In the third operating mode, the weighting combination of energy consumption cost, equipment wear and tear cost, preservation cost, and grid interaction cost is 0.2, 0.1, 0.6, and 0.2, respectively. The preservation cost has a larger weighting, so it can focus more on reducing the preservation cost of the refrigerator.

[0130] In the fourth operating mode, the weights of energy consumption cost, equipment wear and tear cost, preservation cost, and grid interaction cost are 0.2, 0.1, 0.1, and 0.6, respectively. The grid interaction cost has a larger weight, so it can focus more on reducing the grid interaction cost of the refrigerator.

[0131] In the fifth operating mode, the weights of energy consumption cost, equipment wear and tear cost, preservation cost, and grid interaction cost are all 0.25, representing that the weights of operating costs in each dimension are equal. This mode can comprehensively consider the operating costs in each dimension to obtain the target control path.

[0132] Optionally, for the weight of the operating cost under each target dimension in the first operating cost of different dimensions, the target weight of the target dimension is obtained according to the weight of the target dimension in the weight combination corresponding to the multiple operating modes; the target weights under different target temperatures are combined into weight combinations corresponding to the multiple operating modes.

[0133] Here, "multiple operating modes" refers to the refrigerator simultaneously operating in multiple modes. The target weight of the target dimension is obtained based on the weight of the target dimension in the weight combination corresponding to the multiple operating modes. This includes averaging the weights of the same target dimension in the weight combination corresponding to the multiple operating modes to obtain the target weight of that target dimension.

[0134]

[0135] Table 7 For example, referring to Table 7, taking the refrigerator's current operating modes, including the first and third operating modes, as an example, the first weight combination in the first operating mode includes the weights of energy consumption cost, equipment wear and tear cost, preservation cost, and grid interaction cost, which are 0.4, 0.2, 0.1, and 0.3, respectively. The third weight combination in the third operating mode includes the weights of energy consumption cost, equipment wear and tear cost, preservation cost, and grid interaction cost, which are 0.2, 0.1, 0.6, and 0.1, respectively. Therefore, the target weight for energy cost can be obtained by averaging the weights of energy cost in the first and third operating modes, which is 0.3. The target weight for equipment wear and tear cost in the first and third operating modes is... The target weight for equipment wear cost is 0.15 when averaged. The target weight for preservation cost is 0.35 when averaged between the first and third operating modes. The target weight for grid interaction cost is 0.2 when averaged between the first and third operating modes. The final target weights of 0.3, 0.15, 0.35, and 0.2 form a comprehensive weight combination for the first and third operating modes. This weight combination can be used to weight the first operating cost of the refrigerator under different control paths to obtain the second operating cost under different control paths. Finally, the target control path selected from different control paths can better match the current first and third operating modes of the refrigerator.

[0136] S102-2, Based on the combination of the first operating cost generated under different control paths and the weight, the second operating cost under different control paths is obtained.

[0137] Optionally, for the multi-dimensional first operating cost generated under each control path, the multi-dimensional first operating cost can be weighted one by one with the weight combination corresponding to the current operating mode of the refrigerator to obtain the second operating cost under that control path.

[0138] For example, the formula for calculating the second operating cost is as follows: (10) In formula (10), It is the second operating cost under the first control path; This refers to the energy consumption cost incurred by the refrigerator under the first control path. It is the weight of energy consumption cost in the weight combination corresponding to the refrigerator's current operating mode; This refers to the equipment wear and tear costs incurred by the refrigerator under the first control path. It represents the weight of equipment wear and tear costs in the weighted combination corresponding to the refrigerator's current operating mode; This refers to the preservation cost incurred by the refrigerator under the first control path. It represents the weight of preservation cost in the weighted combination corresponding to the refrigerator's current operating mode; It refers to the grid interaction cost incurred by the refrigerator under the first control path. It represents the weight of the grid interaction cost in the weighted combination corresponding to the refrigerator's current operating mode.

[0139] Similarly, the second operating cost under the second control path and the second operating cost under the third control path can also be obtained by using formula (10), which will not be repeated here.

[0140] S102-3, Select the target operating cost that meets the preset conditions from the second operating costs under different control paths.

[0141] The target operating costs that meet the preset conditions include any one of the following: The minimum operating cost is selected from the second operating costs of different control paths, such as the first control path, the second control path, and the third control path, as the target operating cost.

[0142] The target operating cost is selected from the second operating costs of different control paths, such as the first control path, the second control path, and the third control path, and the second operating cost is less than the preset cost.

[0143] Using the above technical solution, before the refrigerator leaves the factory, the first operating cost of the refrigerator under each control path, such as the first control path, the second control path, and the third control path, is calculated. Then, during real-time use after the refrigerator leaves the factory, the current operating mode of the refrigerator is detected, and the weight combination corresponding to the current operating mode is queried. The weights corresponding to the first operating costs of different dimensions in the weight combination are weighted with the first operating costs of different dimensions, so as to obtain the accurate second operating cost of the refrigerator under different control paths. Finally, the target operating cost that meets the preset conditions is selected from the second operating costs corresponding to different control paths.

[0144] Firstly, the weighting of the first operating costs in different dimensions will be adaptively adjusted based on the current operating mode of the refrigerator. This will allow the second operating cost, obtained by adjusting the first operating costs in different dimensions using the weighting of the first operating costs in different dimensions, to adaptively match the operating costs currently incurred by the refrigerator. The resulting second operating cost will be more in line with the current operating status of the refrigerator and will be more realistic and accurate.

[0145] Secondly, after obtaining more accurate second operating costs under different control paths, the target control path corresponding to the target operating cost is selected from the second operating costs of different control paths. Using the target control path to control the refrigerator's operation can also better reduce the operating cost in the current operating mode. For example, as shown in Table 6, the operating mode is the second operating mode. In the second operating mode, the proportion of equipment wear cost is larger under different control paths. Therefore, when selecting the minimum target operating cost from the second operating costs, the focus is on selecting the target operating cost with lower equipment wear cost. Using the target control path corresponding to the target operating cost to control the refrigerator's operation will result in lower equipment wear cost, thus better adapting to the refrigerator's current second operating mode and meeting the user's need to reduce equipment wear.

[0146] Thirdly, when a refrigerator has multiple operating modes, the target weight obtained by averaging the weights of the operating costs of the same target dimension in multiple operating modes can better adapt to multiple operating modes. Finally, the second operating cost obtained by weighting the first operating cost of the refrigerator in multiple operating modes with the weight combination obtained by the target weight combination can more realistically and accurately reflect the operating cost of the refrigerator in multiple operating modes.

[0147] Figure 11 This is an exemplary embodiment involving step S102-1 above, which is used to interpret an exemplary scheme for determining that the refrigerator has entered the first operating mode, including the following steps: S102-A1, in response to the real-time electricity cost of the refrigerator being greater than a first preset threshold, the refrigerator is controlled to enter the first operating mode.

[0148] The first operating mode is the economy mode, which focuses on reducing the refrigerator's energy consumption costs. When the refrigerator's real-time electricity cost exceeds a first preset threshold, it indicates that the refrigerator's current energy consumption cost is high. Therefore, the refrigerator can be controlled to enter the first operating mode, thereby saving energy costs.

[0149] Optionally, it can also respond to a user's first trigger operation to enter the first operating mode and control the refrigerator to enter the first operating mode.

[0150] S102-A2, obtain the first weight combination corresponding to the first operating mode.

[0151] In the first weighted combination, the weight of energy consumption cost is greater than the weight of the other operating costs in the first operating cost.

[0152] For example, referring to Table 6, the first weight combination corresponding to the first operating mode includes the following weights: the weight of energy consumption cost, the weight of equipment wear and tear cost, the weight of preservation cost, and the weight of grid interaction cost are 0.4, 0.2, 0.1, and 0.3, respectively.

[0153] The above technical solution will adaptively adjust the weight ratio of the first operating cost in different dimensions based on the first operating mode of the refrigerator. This will make the second operating cost, which is obtained by correcting the first operating cost in different dimensions of the refrigerator by using the weight of the first operating cost in different dimensions, more realistically and effectively reflect the operating cost generated by the refrigerator in the first operating mode (economic mode).

[0154] Figure 12 This is an exemplary embodiment involving step S102-1 above, which is used to interpret an exemplary scheme for determining whether the refrigerator has entered the second operating mode, including the following steps: S102-B1, in response to the refrigerator's remaining lifespan being less than a second preset threshold, the refrigerator is controlled to enter the second operating mode.

[0155] The second operating mode is the lifespan mode, which focuses on reducing the operating costs incurred by the refrigerator to ensure the freshness of stored items. When the remaining lifespan of the refrigerator is less than the second preset threshold, it indicates that the remaining lifespan of the refrigerator is low. Therefore, the refrigerator can be controlled to enter the second operating mode, thereby reducing the wear and tear costs of various components inside the refrigerator.

[0156] Optionally, the refrigerator can also be controlled to enter the second operating mode in response to a second trigger operation initiated by the user.

[0157] Alternatively, the remaining lifespan of the refrigerator can be determined based on its rated lifespan, equipment wear and tear costs, and rated wear and tear costs, using the following formula: (11) In formula (11), It refers to the remaining lifespan of the refrigerator. This is the refrigerator's rated lifespan, which is also the upper limit of the refrigerator's lifespan preset before it leaves the factory. It's the cost of equipment wear and tear, specifically the current wear and tear cost of the refrigerator. This is the rated wear cost.

[0158] S102-B2, obtain the second weight combination corresponding to the second operating mode.

[0159] In the second weighted combination, the weight of equipment wear and tear costs is greater than the weight of the other operating costs in the first operating cost.

[0160] For example, referring to Table 6, the second weight combination corresponding to the second operating mode includes the following weights: the weight of energy consumption cost, the weight of equipment wear and tear cost, the weight of preservation cost, and the weight of grid interaction cost are 0.2, 0.5, 0.1, and 0.2, respectively.

[0161] The above technical solution will adaptively adjust the weight ratio of the first operating cost in different dimensions based on the second operating mode of the refrigerator. This will make the second operating cost, which is obtained by correcting the first operating cost in different dimensions of the refrigerator by using the weight of the first operating cost in different dimensions, more realistically and effectively reflect the operating cost generated by the refrigerator in the second operating mode (life mode).

[0162] Figure 13 This is an exemplary embodiment involving step S102-1 above, which is used to interpret an exemplary scheme for determining whether the refrigerator has entered a third operating mode, including the following steps: S102-C1, in response to the importance of the stored item being greater than a third preset threshold, the refrigerator is controlled to enter a third operating mode.

[0163] The third operating mode is the preservation mode, which prioritizes maintaining the freshness of stored items while reducing operating costs. When the importance of stored items exceeds a third preset threshold, it indicates that the items are valuable and / or highly sensitive to temperature. Therefore, the refrigerator can be controlled to enter the third operating mode, thereby reducing the additional operating costs incurred by the refrigerator in maintaining the freshness of stored items.

[0164] Optionally, it can also respond to a third trigger operation triggered by the user to enter the third operating mode, and control the refrigerator to enter the third operating mode.

[0165] S102-C2, obtain the third weight combination corresponding to the third operating mode.

[0166] In the third weighting combination, the weight of the preservation cost is greater than the weight of the other operating costs in the first operating cost.

[0167] For example, referring to Table 6, the third weight combination corresponding to the third operating mode includes the following weights: the weight of energy consumption cost, the weight of equipment wear and tear cost, the weight of preservation cost, and the weight of grid interaction cost are 0.2, 0.1, 0.6, and 0.1, respectively.

[0168] The above technical solution will adaptively adjust the weight ratio of the first operating costs in different dimensions based on the third operating mode of the refrigerator. This will make the second operating cost, which is obtained by correcting the first operating costs in different dimensions of the refrigerator by using the weights of the first operating costs in different dimensions, more realistically and effectively reflect the operating costs generated by the refrigerator in the third operating mode (freshness mode).

[0169] Figure 14 This is an exemplary embodiment involving step S102-1 above, which is used to interpret an exemplary scheme for determining whether the refrigerator has entered the fourth operating mode, including the following steps: S102-D1, in response to receiving a power grid abnormality signal, controls the refrigerator to enter the fourth operating mode.

[0170] The fourth operating mode is the grid mode, which focuses more on responding to grid demands. When an abnormal grid signal is received, it indicates that there is a grid demand. At this time, the refrigerator can be controlled to enter the fourth operating mode to perform actions that meet the grid demand and reduce the additional operating costs incurred by the refrigerator in meeting the grid demand.

[0171] Optionally, it can also respond to a fourth trigger operation triggered by the user to enter the fourth operating mode, and control the refrigerator to enter the fourth operating mode.

[0172] S102-D2, obtain the fourth weight combination corresponding to the fourth operating mode.

[0173] In the fourth weighting combination, the weight of the power grid interaction cost is greater than the weight of the other operating costs in the first operating cost.

[0174] For example, referring to Table 6, the fourth weight combination corresponding to the fourth operating mode includes the following weights: the weight of energy consumption cost, the weight of equipment wear and tear cost, the weight of preservation cost, and the weight of grid interaction cost are 0.2, 0.1, 0.1, and 0.6, respectively.

[0175] The above technical solution will adaptively adjust the weight ratio of the first operating cost in different dimensions based on the current fourth operating mode of the refrigerator. This will make the second operating cost, which is obtained by correcting the first operating cost in different dimensions of the refrigerator by using the weight of the first operating cost in different dimensions, more realistically and effectively reflect the operating cost generated by the refrigerator in the fourth operating mode (grid interaction mode).
