Description

Technical Field

[0001] This disclosure relates to the field of smart home technology, and in particular to a defrosting control method, device and refrigeration equipment. Background Technology

[0002] In related technologies, during the use of refrigeration equipment such as refrigerators, frost buildup on the evaporator can lead to problems such as decreased thermal efficiency and increased energy consumption. Therefore, defrosting is required. For example, when the refrigeration equipment operates for a fixed period of time, the equipment is controlled to perform a defrosting operation. Although this can achieve a certain defrosting effect, problems such as insufficient defrosting, excessive defrosting, or frequent defrosting still exist, resulting in poor defrosting accuracy. Summary of the Invention

[0003] To overcome the problems existing in the related technologies, this disclosure provides a defrosting control method, device and refrigeration equipment, which can accurately determine the start and end of defrosting, avoid erroneous defrosting operations and thus improve defrosting accuracy.

[0004] According to a first aspect of the present disclosure, a defrosting control method is provided, comprising:

[0005] Acquire initial temperature data related to the refrigeration of the refrigeration equipment;

[0006] If the first temperature data of the refrigeration equipment at the moment of refrigeration shutdown meets the defrosting start condition, then the refrigeration equipment is controlled to perform this round of defrosting operation, and the second temperature data related to the defrosting of the refrigeration equipment is obtained;

[0007] Based on the second temperature data, defrosting operation duration, and defrosting parameters, the refrigeration equipment is controlled to end the current defrosting operation, and the defrosting parameters are adjusted for use in the next defrosting operation.

[0008] According to a second aspect of the present disclosure, a defrosting control device is provided, comprising:

[0009] The acquisition unit is used to acquire the first temperature data related to refrigeration from the refrigeration equipment;

[0010] The control unit is configured to control the refrigeration equipment to perform the current defrosting operation if the first temperature data of the refrigeration equipment at the time of refrigeration shutdown meets the defrosting start condition, and to acquire the second temperature data related to the defrosting of the refrigeration equipment.

[0011] The control unit is also configured to control the refrigeration equipment to end the current defrosting cycle based on the second temperature data, the defrosting operation duration, and the current defrosting parameters, and to adjust the defrosting parameters for use in the next defrosting operation.

[0012] According to a third aspect of the present disclosure, a refrigeration apparatus is provided, comprising:

[0013] processor;

[0014] Memory used to store processor-executable instructions;

[0015] The processor is configured to: acquire first temperature data related to refrigeration of the refrigeration equipment; if the first temperature data of the refrigeration equipment at the time of refrigeration shutdown meets the defrosting start condition, control the refrigeration equipment to perform the current defrosting operation and acquire the second temperature data related to the defrosting of the refrigeration equipment; based on the second temperature data, the defrosting operation duration and defrosting parameters, control the refrigeration equipment to end the current defrosting operation and adjust the defrosting parameters for use in the next defrosting operation.

[0016] The technical solution provided by the embodiments of this disclosure can include the following beneficial effects: by using the first temperature data at the moment of refrigeration shutdown as the basis for defrosting initiation, and combining the second temperature data during the defrosting process, the defrosting operation duration, and the defrosting parameters called in this round as the basis for exit, and simultaneously writing the exit result of this round back into the parameters of the next round, a continuous control link covering defrosting initiation, defrosting execution, and post-defrosting parameter correction is formed. This implementation method enables the initiation and exit timing of each round of defrosting to correspond to the actual temperature state of the current round, and maintains the continuity of adjustment results in subsequent rounds, thereby making evaporator frosting control more stable and suppressing compartment temperature fluctuations and ineffective defrosting times. Therefore, the method provided by the embodiments of this disclosure can more accurately determine the start and end timing of defrosting, avoid erroneous defrosting operations, and thus improve defrosting accuracy and defrosting effect.

[0017] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0023] Figure 5 This is a schematic diagram of the structure of a chip system according to some embodiments of the present disclosure. Detailed Implementation

[0024] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0025] The embodiments described in the following examples of this disclosure are not representative of 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.

[0026] Figure 1 This is a schematic diagram illustrating an application scenario of a defrosting control method according to some embodiments of the present disclosure.

[0027] like Figure 1 As shown, this application scenario is a simplified schematic of a refrigeration equipment structure, specifically including components such as a compressor, condenser, capillary tube, damper, and refrigeration evaporator, which delivers cooling capacity to the refrigerator compartment and the freezer compartment.

[0028] In this embodiment, when the refrigeration equipment is initially powered on, the compressor generates gas pressure, turning the refrigerant into superheated vapor and delivering it to the condenser. The condenser releases a large amount of heat to the outside air, cooling and liquefying the refrigerant. As the refrigerant passes through the capillary tube, due to the throttling effect of the capillary tube, the refrigerant becomes a gas-liquid two-phase mixture and enters the refrigeration evaporator for heat absorption and refrigeration, where the liquid completely evaporates into low-temperature vapor. A fan continuously blows air from inside the unit through the evaporator fins, cooling the air and producing cold air. Part of this cold air is used for refrigeration in the freezer compartment, and when the refrigerator door is opened, some cold air enters the refrigerator compartment for refrigeration. The temperature of the refrigeration evaporator remains below 0°C throughout operation, causing frost to form from moisture in the air. Over time, a large amount of frost accumulates on the refrigeration evaporator, affecting the use of the refrigeration equipment, such as insufficient cooling, leading to spoilage of stored food.

[0029] Therefore, related technologies employ timed defrosting operations, such as automatically controlling the defrosting of refrigeration equipment every 8 hours. The defrosting process primarily involves first stopping the refrigeration operation, for example, by stopping the compressor, stopping the evaporator fan, and closing the refrigerator damper. Then, the defrosting heating element at the bottom of the evaporator heats the evaporator, gradually melting the frost layer on its surface, thus completing the defrosting process.

[0030] As described above, the defrosting operation in related technologies cannot determine the appropriate start and end times for different usage scenarios. This leads to issues such as starting defrosting too early or too late, insufficient defrosting, or excessive defrosting. For example, when users frequently open and close doors, the ambient humidity changes significantly, or the load fluctuates noticeably, a single judgment result may not accurately match the actual working conditions, resulting in problems such as insufficient defrosting, excessive defrosting, or frequent defrosting, leading to poor defrosting accuracy.

[0031] To this end, some embodiments of this disclosure propose the following technical concept: determining whether defrosting should begin by combining time and temperature conditions, and setting multiple determination conditions for ending defrosting, in order to meet the defrosting needs of various different scenarios, ensuring that the frost layer can melt more fully and improving the accuracy of defrosting.

[0032] The defrosting control method proposed in this disclosure will now be described in detail with reference to specific embodiments and accompanying drawings.

[0033] Figure 2 This is a flowchart illustrating a defrosting control method according to some embodiments of the present disclosure, such as... Figure 2 As shown, this defrosting control method is used in terminals, but it can also be used in terminal devices such as servers and cloud platforms that communicate with terminals or refrigeration equipment. This embodiment does not limit its application to these applications. A defrosting control method includes the following steps:

[0034] S201: Obtain first temperature data related to the refrigeration of the refrigeration equipment.

[0035] In this embodiment, the refrigeration equipment can be a refrigeration appliance that generates cold air and frosts during the refrigeration process. For example, the refrigeration equipment may include refrigerators, freezers, and cold storage boxes, etc., and this embodiment does not limit this to any particular type. The first temperature data related to refrigeration may be the relevant temperature data involved in the entire refrigeration process when the refrigeration equipment is refrigerating. For example, the first temperature data may include the temperature of the cold storage compartment, the temperature of the freezer compartment, and the temperature of the freezer evaporator collected at various time points.

[0036] In this embodiment, the first temperature data at different times can be used to determine whether the refrigeration equipment can start defrosting at the corresponding time.

[0037] S202: If the first temperature data of the refrigeration equipment at the moment of refrigeration shutdown meets the defrosting start condition, then control the refrigeration equipment to perform this round of defrosting operation and obtain the second temperature data related to the defrosting of the refrigeration equipment.

[0038] In this embodiment, the refrigeration shutdown time can be the time when the compressor stops after refrigeration ends. This shutdown time serves as the judgment time point, and the first temperature data is used as the basis for determining whether defrosting can begin. The first temperature data can be the freezer compartment temperature and the freezer evaporator temperature. The temperature difference between these two data points is then used to determine whether the defrosting start condition is met. This dual determination avoids misidentification caused by drastic temperature changes within a single temperature control cycle, such as frequent opening of the refrigerator by the user causing a rapid temperature difference that quickly reaches the defrosting start condition. Furthermore, if the temperature is lower and the temperature control requirements are higher, the freezer evaporator temperature mainly follows the changes in freezing demand. Using the temperature difference more accurately reflects the degree of frost formation on the evaporator, thus providing a more accurate judgment on whether to begin defrosting.

[0039] In this embodiment, if the first temperature data at the moment of refrigeration shutdown meets the defrosting start condition, the refrigeration equipment is controlled to perform this round of defrosting operation. The defrosting operation process is as follows: Figure 1 The embodiments shown have already been described, so they will not be repeated here. During the defrosting operation, it is also necessary to acquire second temperature data related to the defrosting of the refrigeration equipment in real time, so as to determine when to exit the defrosting operation based on the second temperature data. The second temperature data can be temperature data or temperature change data representing different locations or devices during this round of defrosting operation. For example, the temperature of the freezer compartment at different times, the temperature of the freezer evaporator, etc. In this embodiment, these temperature data can be read and collected from temperature sensors to obtain the second temperature data.

[0040] S203: Based on the second temperature data, defrosting operation duration, and defrosting parameters, control the refrigeration equipment to end the current defrosting operation and adjust the defrosting parameters for use in the next defrosting operation.

[0041] In this embodiment, the defrosting operation duration can be the duration of the defrosting operation recorded after the start of the current defrosting operation. Defrosting parameters can be judgment parameters or defrosting operation parameters used to determine before, during, and at the end of the defrosting operation. For example, defrosting parameters may include the judgment conditions for the start of the next defrosting operation, the defrosting cycle, and the duration of the defrosting operation.

[0042] In this embodiment, the defrosting operation of the refrigeration equipment can be controlled to end by stopping the defrosting heating element at the bottom of the evaporator and restarting the refrigeration operation. Based on the second temperature data, defrosting operation duration, and defrosting parameters at the end of the current defrosting operation, the exit timing for ending the current defrosting operation can be determined. Based on this timing, adjustments to parameters for the next defrosting operation can be made to further improve the accuracy of the next defrosting operation. For example, if the second temperature data reaches the defrosting end condition before the preset defrosting operation duration, it indicates that there is a significant amount of frost that has not been completely defrosted within the preset duration. In this case, the defrosting duration for the next operation should be adjusted to shorten the waiting period between the two defrosting operations, allowing for a more thorough defrosting next time.

[0043] In summary, the defrosting control method provided in this disclosure uses the first temperature data at the moment of refrigeration shutdown as the basis for starting defrosting, and combines the second temperature data during the defrosting process, the defrosting operation duration, and the defrosting parameters called in this round as the basis for determining whether to exit the defrosting operation. Simultaneously, the exit result of this round of defrosting operation is used as a reference for parameter adjustment in the next round of defrosting operation, forming a continuous control link covering the start of defrosting, the execution of defrosting, and the parameter correction after defrosting. This implementation ensures that the start and exit times of each round of defrosting correspond to the actual temperature state of the current round, and maintains the continuity of adjustment results in subsequent rounds, thereby making the evaporator frosting control more stable and effectively controlling compartment temperature fluctuations and the number of ineffective defrosting operations. Therefore, the method provided in this disclosure can more accurately determine the start and end times of defrosting, avoid erroneous defrosting operations, and thus improve defrosting accuracy and defrosting effect.

[0044] Based on the above embodiments, as an optional embodiment of this application, the first temperature data includes the freezer room temperature and the first temperature of the freezer evaporator related to refrigeration. In step S202, if the first temperature data of the refrigeration equipment at the time of refrigeration shutdown meets the defrosting start condition, it includes: if the difference between the freezer room temperature and the first temperature of the freezer evaporator at the time of refrigeration shutdown reaches the defrosting temperature difference threshold, then it is determined that the first temperature data meets the defrosting start condition.

[0045] In this embodiment, the evaporator gradually frosts up during the refrigeration operation. The end time of each refrigeration operation is used as the judgment time, and the difference between the freezer compartment temperature and the evaporator temperature at the end of the refrigeration operation is defined as the temperature difference. A temperature difference threshold, namely the defrost temperature difference threshold, is set as the judgment condition for whether to perform the defrost operation. This avoids misidentification caused by changes in the freezer compartment temperature within a single temperature control cycle. Therefore, by uniformly judging whether the difference between the freezer compartment temperature and the first temperature of the evaporator reaches the defrost temperature difference threshold at the moment of refrigeration shutdown, the judgment result is more accurate, thus making the timing of defrosting more precise.

[0046] In this embodiment, the temperature Tdj of the freezer room related to refrigeration can be collected by a temperature sensor installed in the freezer room, and the first temperature Tz1 of the freezer evaporator related to refrigeration can be collected by a temperature sensor installed on the freezer evaporator. The difference between the freezer room temperature Tdj and the first temperature Tz1 of the freezer evaporator is defined as ΔT. An initial defrosting temperature difference threshold ΔT0 is preset as the judgment condition for whether to perform defrosting operation. When ΔT reaches ΔT0, it means that the defrosting start condition is met.

[0047] In this embodiment, the difference between the refrigerator compartment temperature and the first temperature of the evaporator can be used as the defrosting start criterion. This ensures that defrosting triggering corresponds to the actual thermal state at the time of shutdown, making the determination of the defrosting start condition closer to the current degree of frost formation and providing a stable basis for subsequent defrosting control. This method enables the refrigeration equipment to use a uniform and adjustable threshold for judgment under different operating conditions, improving the accuracy of defrosting start condition identification and reducing the deviation in defrosting timing caused by judging a fixed single temperature point.

[0048] Furthermore, based on the above embodiments, as an optional embodiment of this disclosure, step S203, according to the second temperature data, defrosting operation duration, and defrosting parameters, controls the refrigeration equipment to end the current defrosting operation and adjusts the defrosting parameters, including:

[0049] S203a: If the defrosting operation time reaches the preset defrosting time first, the refrigeration equipment will be controlled to end the current defrosting operation and the defrosting parameters will be adjusted.

[0050] In this embodiment, the preset operation duration can be the duration of the defrosting operation recorded after the defrosting operation begins, or the preset defrosting duration can be the total defrosting operation duration preset based on the defrosting program. If the defrosting operation duration first reaches the preset defrosting duration, the duration condition is triggered, thereby controlling the refrigeration equipment to stop the heating defrosting operation. At the same time, relevant parameters during this round of defrosting, such as the preset defrosting duration and the defrosting temperature difference threshold, are collected and adjusted to ensure more thorough defrosting in the next round and avoid insufficient defrosting.

[0051] In this embodiment, the pre-cooling time is a limited time for the evaporator to run continuously before the defrosting operation. During this time, the temperatures of the refrigerator compartment and the freezer compartment are lowered in advance. During the pre-cooling time, the refrigeration stops when the temperature of the refrigerator compartment reaches the pre-cooling stop point Tcti, the refrigerator damper is closed, and the system switches to freezer cooling until the pre-cooling time tLi ends, where i represents the number of cooling cycles.

[0052] S203b: If the second temperature data reaches the preset defrost stop condition first, the refrigeration equipment is controlled to end the current defrost operation and the defrost parameters are adjusted.

[0053] In this embodiment, if the second temperature data reaches the preset defrosting stop condition first, that is, if the second temperature data reaches the preset temperature threshold or temperature rise threshold, it indicates that the defrosting scenario of the refrigeration equipment is different from the previous one. In order to avoid over-defrosting or under-defrosting, which would cause the internal temperature of the refrigeration equipment to rise, affecting food preservation and increasing unnecessary energy consumption, the refrigeration equipment needs to be controlled to end the current defrosting operation before the preset defrosting time is reached. The defrosting parameters are then adjusted to ensure better completion of the next defrosting operation.

[0054] In this embodiment, adjusting the defrosting operation can involve increasing, decreasing, or keeping some parameters associated with the defrosting operation unchanged to adapt to different defrosting scenarios or defrosting operations with different defrosting thicknesses.

[0055] In this embodiment, the defrosting control method provided here no longer relies on a single condition to determine the timing of defrosting termination. Instead, it uses both time and temperature conditions as constraints, and adjusts the defrosting parameters based on the results of the current defrosting operation to better complete subsequent defrosting operations. This makes the timing of defrosting termination more closely match the actual frosting state, reduces deviations in subsequent defrosting parameters, and further improves defrosting accuracy.

[0056] Based on the above embodiments, in an optional embodiment of this application, step S203a includes the following steps: if the defrosting operation time first reaches the preset defrosting time, then control the refrigeration equipment to end the current defrosting operation, and reduce the defrosting temperature difference threshold and pre-cooling time for the next defrosting operation, increase the preset defrosting time, and keep the pre-cooling stop point unchanged.

[0057] In this embodiment, the defrost temperature difference threshold is used as a criterion for determining whether the refrigeration equipment enters the defrost operation. When the refrigeration ends, if the difference between the temperature of the freezer compartment and the first temperature of the freezer evaporator is greater than or equal to the defrost temperature difference threshold, it indicates that the defrost initiation condition is met. Then, the refrigeration equipment is controlled to end the current defrost operation. Simultaneously, to improve the defrost effect of the next defrost operation, the defrost temperature difference threshold can be reduced to make it easier to trigger the next defrost operation, reduce the pre-cooling time, and better complete the refrigeration operation.

[0058] In this embodiment, taking the first defrosting operation after the refrigeration equipment is initially powered on as an example, if the temperature rise of the refrigerator compartment, the freezer compartment, and the evaporator does not reach the threshold after the preset defrosting time t0, it indicates that there is a lot of frost and the frost layer was not completely defrosted within the defrosting time, meaning the defrosting time is insufficient. The temperature difference ΔT1 between the freezer compartment and the evaporator is recorded at this time. The preset defrosting temperature difference ΔT2, which is the condition for determining whether to initiate the next defrosting operation, decreases, meaning the condition for triggering the defrosting operation is simpler and easier to initiate. Therefore, the defrosting cycle is shortened, the next preset defrosting time t2 is lengthened, the next defrosting operation is more thorough, and the next pre-cooling time tL2 is shortened, which can reduce energy consumption, while the pre-cooling shutdown point Tct0 remains unchanged. Completing these parameter adjustments completes the adjustment of the defrosting parameters for the defrosting operation.

[0059] In this embodiment, the result of the current defrosting operation ending because the defrosting time expires first can be used as the basis for correcting the defrosting parameters of the next defrosting operation. This allows the preset defrosting temperature difference, pre-cooling time, and defrosting duration to be adjusted in conjunction with the actual operating status of the refrigeration equipment, reducing energy consumption while improving the accuracy and defrosting effect of subsequent defrosting operations.

[0060] Based on the above embodiments, in an optional embodiment of this application, the second temperature data includes defrosting-related data on the temperature rise of the refrigerator compartment, the temperature rise of the freezer compartment, and the second temperature of the freezer evaporator; step S203b includes:

[0061] Step b1: If the temperature rise data of the cold room reaches the temperature rise threshold of the cold room first, then control the refrigeration equipment to end the current defrosting operation, and reduce the defrosting temperature difference threshold and pre-cooling stop point for the next defrosting operation, increase the pre-cooling time, and keep the preset defrosting time unchanged.

[0062] In this embodiment, the exit conditions for the current defrosting cycle can be determined based on the prior relationship between the defrosting operation duration and the second temperature data. After exiting, the defrosting parameters are updated. The defrosting temperature difference threshold and the pre-cooling shutdown point can be written into the next round of defrosting control parameters. The pre-cooling time constrains the duration of pre-cooling before the next round of defrosting, and the preset defrosting duration constrains the allowable duration of the next round of defrosting. To facilitate parameter adjustment under different operating conditions, the pre-cooling shutdown point can be defined as the target point where the compressor stops when the refrigerator compartment temperature drops to a predetermined value. The pre-cooling time can be the duration of pre-cooling after the refrigeration shutdown and before entering the defrosting phase. The preset defrosting duration can be the longest allowable duration for the current or next round of defrosting.

[0063] For example, taking the first defrosting operation after the refrigeration equipment is first powered on as an example, if the preset defrosting time t0 has not been reached, and neither the freezer room temperature rise nor the second temperature of the evaporator has reached the threshold, while the refrigerator room temperature rise reaches the refrigerator room temperature rise threshold Tcs first, it indicates that there is a lot of frost in this defrosting operation and it has not been completely defrosted. However, the refrigerator room temperature is too high and the temperature rise is too large. In order to avoid damage to the food in the refrigerator room, the defrosting needs to be ended early. Record the temperature difference ΔT1 between the freezer room temperature and the second temperature of the evaporator at this time. Decrease the entry condition ΔT2 for the next defrosting operation, shorten the defrosting cycle, and keep the next defrosting operation time t2 unchanged. At the same time, lengthen the next pre-cooling time tL2, decrease the next pre-cooling stop point Tct0, and lower the refrigerator room temperature in advance to avoid the refrigerator room temperature rising too high during the next defrosting process.

[0064] Alternatively, step b2: If the freezer room temperature rise data reaches the freezer room temperature rise threshold first, then control the refrigeration equipment to end the current defrosting operation, and reduce the defrosting temperature difference threshold for the next defrosting operation, increase the pre-cooling time and pre-cooling stop point, and keep the preset defrosting time unchanged.

[0065] In this embodiment, when the temperature rise data of the refrigerator compartment reaches the refrigerator compartment temperature rise threshold first, the controller determines that the refrigerator compartment is significantly affected by defrosting, and thus ends the current defrosting operation. It then lowers the defrosting temperature difference threshold and the pre-cooling stop point, while increasing the pre-cooling time used in the next defrosting operation, while keeping the preset defrosting duration unchanged. This adjustment method ensures that the refrigerator compartment has sufficient cooling margin when the next defrosting operation starts, and triggers the defrosting operation earlier. When the temperature rise data of the freezer compartment reaches the freezer compartment temperature rise threshold first, the controller ends the current defrosting operation and lowers the defrosting temperature difference threshold used for the next defrosting operation, while increasing the pre-cooling time, while keeping the preset defrosting duration unchanged, thus improving the adaptability of the next defrosting operation to freezer compartment temperature fluctuations.

[0066] For example, taking the first defrosting operation after the refrigeration equipment is first powered on as an example, if the preset defrosting time t0 has not been reached, and the temperature rise data of the refrigerator compartment and the second temperature of the freezer evaporator have not reached the threshold, but the temperature rise of the freezer compartment reaches the freezer compartment temperature rise threshold Tds first, it means that there is a lot of frost or the frost layer is thick, resulting in the frost not being completely removed in this round of defrosting. However, the temperature of the freezer compartment is too high and the temperature rise is too large. In order to avoid damage to the food in the freezer compartment, the defrosting operation needs to be ended early. The temperature difference ΔT1 between the temperature of the freezer compartment and the temperature of the freezer evaporator is recorded at this time. The judgment condition ΔT2 for entering the next defrosting operation decreases, the defrosting cycle is shortened, and the preset defrosting time t2 remains unchanged. At the same time, the next pre-cooling time tL2 is lengthened, the next pre-cooling stop point Tct0 is increased, the temperature of the refrigerator compartment is appropriately increased, and the temperature of the freezer compartment is lowered in advance to avoid the temperature of the freezer compartment rising too high during the next defrosting process.

[0067] Alternatively, in step b3: if the second temperature of the refrigeration evaporator reaches the evaporator temperature threshold first, then control the refrigeration equipment to end the current defrosting operation, and reduce the preset defrosting time for the next defrosting operation, increase the defrosting temperature difference threshold, and keep the pre-cooling time and pre-cooling stop point unchanged.

[0068] In this embodiment, when the second temperature of the refrigeration evaporator reaches the evaporator temperature threshold first, the controller ends the current defrosting operation and reduces the preset defrosting time available for the next defrosting operation, increases the defrosting temperature difference threshold, and keeps the pre-cooling time and pre-cooling stop point unchanged, so that the subsequent defrosting duration matches the evaporator frost layer state.

[0069] For example: if the preset defrosting time t0 is not reached, and there are no corresponding thresholds for the temperature rise data of the refrigerator room and the freezer room, and the second temperature of the freezer evaporator reaches the freezer evaporator temperature threshold Tz first, it means that the evaporator frost is thin. Then the judgment condition for the next defrosting operation, the defrosting temperature difference threshold ΔT2, increases, the defrosting cycle is lengthened, the time t2 of the next defrosting operation decreases, and the next pre-cooling time tL2 and the next pre-cooling shutdown point Tct2 remain unchanged.

[0070] In summary, in this embodiment, by using data on the temperature rise of the refrigerator compartment, the temperature rise of the freezer compartment, and the different values ​​of the second temperature of the freezer evaporator during the defrosting process, subsequent defrosting parameters can be differentiated and corrected. This makes the defrosting end determination and the setting of the next round of defrosting parameters more closely match the frost state in the actual defrosting scenario. This enables a continuous parameter adaptive relationship between each round of defrosting and maintains stable control of the compartment temperature and evaporator state.

[0071] In addition, to avoid excessive heat generation during defrosting, which could cause the temperature in the refrigerator or freezer compartment to rise too quickly and lead to errors in judging when to stop defrosting, thus affecting defrosting efficiency, and also to prevent food damage due to excessively rapid temperature rise, the temperature in the refrigerator or freezer compartment can be lowered in advance before the defrosting operation.

[0072] Specifically, in an optional embodiment of this application, a defrosting control method further includes, before controlling the refrigeration equipment to perform the current defrosting operation in step S202:

[0073] Step A: Control the refrigeration equipment to perform defrosting and pre-cooling operations until the pre-cooling shutdown point is reached, and control the refrigeration damper to close.

[0074] In this embodiment, the defrosting pre-cooling operation can be as follows: The freezer evaporator runs continuously for a limited time before the defrosting operation. During this limited time, the temperature of the refrigerator and freezer compartments is lowered in advance to prevent the temperature of either compartment from rising too quickly during the defrosting operation, which could damage the food or prematurely end the defrosting process. The pre-cooling shutdown point can indicate that the real-time temperature of the refrigerator compartment has reached a low value, such as 5 degrees Celsius or 4 degrees Celsius. When the refrigerator damper is closed, no cold air is transported from the freezer compartment to the refrigerator compartment for refrigeration. The refrigerator compartment maintains a low temperature range for a short period in preparation for the subsequent defrosting operation.

[0075] Step B: Control the refrigeration equipment to perform refrigeration operation until the pre-cooling time is reached.

[0076] In this embodiment, the pre-cooling time can be the time during which the evaporator is allowed to run continuously before the defrosting operation. Once the pre-cooling operation duration reaches the pre-cooling time, it indicates that the defrosting operation should proceed. In this embodiment, the refrigeration operation can be a process of continuing to control the compressor and evaporator after closing the refrigerator damper. During the pre-cooling time, the refrigeration operation stops when the real-time temperature of the refrigerator compartment reaches the pre-cooling stop point Tcti. At this time, the refrigerator damper needs to be closed, and the system switches to refrigeration until the pre-cooling time tLi ends. This completes the preparation work before defrosting.

[0077] In this embodiment, the temperatures of the refrigerator and freezer compartments can be lowered in advance before the start of the defrosting operation. After the damper is closed, the heat exchange on the refrigerator side is restricted, while the freezer side can continue to supplement the cooling effect. This makes the temperature states of the refrigerator and freezer compartments more consistent at the start of the defrosting operation, thereby improving the matching degree between defrosting control and subsequent temperature adjustment. It can also prevent the temperature from rising too quickly during the defrosting operation, which could damage the food, and prevent the defrosting termination condition from being triggered prematurely, thus affecting the defrosting effect.

[0078] Furthermore, to avoid the rapid drop in evaporator temperature leading to... The temperature difference during defrosting is too large. This triggers the next defrosting operation ahead of schedule. In an optional embodiment of this application, the process further includes the following step before step S201:

[0079] Step C: When the refrigeration equipment starts cooling operation, start the defrost protection timer to obtain the cooling duration.

[0080] Step D: If the cooling time is greater than or equal to the preset protection time, determine whether the first temperature data of the refrigeration equipment at the moment of cooling shutdown meets the defrosting start condition.

[0081] In this embodiment, after the defrost protection timer is activated, it can establish a balance between the evaporator temperature and the refrigerator and freezer compartment temperatures within a preset protection time, avoiding the brief temperature difference peak caused by a rapid drop in evaporator temperature. The cooling duration is the time recorded after the defrost protection timer is activated, from the start of the cooling operation to the present. If the cooling duration is greater than or equal to the preset protection duration, it is further determined whether the first temperature data of the refrigeration equipment at the moment of cooling shutdown meets the defrost start condition.

[0082] In this embodiment, a protection time window can be set during the initial cooling stage. This ensures that the determination of whether the first temperature data meets the defrosting start condition occurs after the cooling duration is greater than or equal to a preset protection time. This allows the timing of the defrosting operation to be based on a temperature closer to the actual frosting state, thus aligning the start time of the defrosting operation with the actual operating conditions. Because the joint judgment relationship between the defrosting protection timer and the first temperature data is clearly defined, the controller can maintain a stable defrosting operation start rhythm under different loads and environmental conditions, thereby improving the continuity and accuracy of defrosting control.

[0083] Alternatively, in step E: if the cooling time is less than the preset protection time, control the cooling equipment to continue performing the cooling operation.

[0084] In this embodiment, if the cooling time is less than the preset protection time, it means that the defrosting operation has not been triggered, and the judgment of the defrosting start condition is not executed, so that the compressor, fan and related refrigeration execution components remain in the refrigeration operation state.

[0085] In this embodiment, by continuously maintaining cooling operation before the preset protection time is reached, and defrosting judgment only intervening after the protection time, the cooling operation state remains stable, and subsequent temperature data related to the start of defrosting becomes more consistent, thereby improving the consistency of control judgment and thus improving the accuracy of defrosting. Based on the above embodiment, as an optional embodiment of this application, it further includes:

[0086] Step F: If the first temperature data of the refrigeration equipment at the moment of refrigeration shutdown does not meet the defrosting start condition, then control the refrigeration equipment to continue to perform refrigeration operation.

[0087] In this embodiment, if the first temperature data does not meet the defrosting start condition, the defrosting operation is not triggered. Instead, the current start-stop strategy of the refrigeration circuit is maintained, allowing the refrigeration equipment to continue performing refrigeration operations. This enables the subsequently collected first temperature data to further reflect the chamber cooling and evaporator frosting evolution.

[0088] In this embodiment, the refrigeration operation can continue even when the first temperature data does not meet the defrosting start condition. The defrosting process will not be prematurely triggered when there is insufficient frost. The controller can re-make the judgment based on the accumulated temperature changes during subsequent operation, so that the defrosting start is consistent with the actual frost state, and the refrigeration equipment maintains a more stable operating state under different ambient temperature, humidity and load conditions.

[0089] Based on the above embodiments, in an optional embodiment of this disclosure, after step S203, step G is further included: if the defrosting operation of the refrigeration equipment is completed, the defrosting protection timer is reset to zero.

[0090] In this embodiment, the end of the defrosting operation signifies the end of the current defrosting cycle and the start of the next defrosting cycle. Similarly, when the refrigeration operation begins, a defrosting protection timer is activated to further determine the cooling duration. This avoids errors in the calculation of cooling duration between two adjacent defrosting cycles and improves the control accuracy of the defrosting operation.

[0123] Those skilled in the art will also understand that the various illustrative logical blocks and steps listed in the embodiments of this application can be implemented by electronic hardware, computer software, or a combination of both. Whether such functionality is implemented through hardware or software depends on the specific application and the overall system design requirements. Those skilled in the art can implement the functionality using various methods for each specific application, but such implementation should not be construed as exceeding the scope of protection of the embodiments of this application.

[0124] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0125] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0126] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0127] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0128] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0129] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0130] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0131] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding the specification and drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous for any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0132] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0133] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
