[0017] It should be noted that the terms "first", "second", etc. in the specification, claims, and drawings of the present invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way are interchangeable where appropriate so that the embodiments of the present invention can be implemented in an order other than the following diagrams or descriptions.

For example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or inherent to these processes, methods, products, or devices.

[0018] In view of the problem in the prior art that traditional refrigerator dampers cannot achieve precise temperature control in each area, the food preservation effect is poor, and it is easy to cause waste of cold air and energy consumption, the embodiments of the present invention provide a damper control method, device, refrigeration device and storage medium. The damper control method and damper control device are applied to the refrigeration device, and the damper control method is implemented based on the damper control device provided by the embodiments of the present invention.

[0019] Specifically, the refrigeration device provided in an embodiment of the present invention performs temperature control based on the damper control method. The refrigeration device may include household appliances such as refrigerators, wherein the refrigeration device is a dual-circulation system with a refrigerator compartment and a freezer compartment provided therein. The refrigeration device includes a first damper and a second damper, so as to accurately control the cold distribution in the refrigerator compartment and the freezer compartment through intelligent regulation of the switch status of the two dampers, avoid waste of cold air, reduce energy consumption wasted due to frequent starting and stopping of the compressor, optimize the humidity and temperature environment inside the refrigeration device, and slow down the loss of water and nutrients in food.

[0020] Among them, the damper control method first obtains the working state of the refrigeration system and multiple environmental parameters, the working state is used to indicate the current working state of the refrigeration device, and the multiple environmental parameters are used to indicate the temperature and humidity changes inside and outside the refrigeration device, including at least one of the external ambient temperature, the internal ambient temperature, the internal ambient humidity and the number of door openings; then, when the working state indicates that the refrigeration device is in a transient operating state, the multiple environmental parameters are normalized to obtain multiple normalized data; then, according to the multiple normalized data and the weight coefficients corresponding to each environmental parameter, a refrigeration score is determined, and the refrigeration score is used to indicate the current refrigeration state of the refrigeration device; then, according to the refrigeration score, the opening of the second damper is adjusted, and the opening of the second damper is positively correlated with the refrigeration score; and, during the opening adjustment process of the second damper, the phase change material of the first damper undergoes a volume change based on the change in the internal ambient temperature of the refrigeration device to passively control the opening of the first damper.

[0021] In this way, the damper control method controls the opening of the second damper based on the algorithm according to the operating status of the refrigeration device and multiple environmental parameters, and cooperates with the passive phase change drive of the first damper. It can effectively improve the accuracy of temperature control in different areas inside the refrigeration device, optimize the humidity and temperature environment inside the refrigeration device, effectively slow down the rate of water loss and nutrient loss of food, and improve the preservation effect; at the same time, it can achieve precise distribution of cooling capacity, effectively avoid waste of cold air, reduce the number of frequent starts and stops of the compressor, and greatly reduce energy consumption.

[0022] The following is a detailed description of the damper control method according to the embodiment of the present invention. Figure 1 , the method comprising: S101: Acquire the operating status and multiple environmental parameters of the refrigeration device.

[0023] Among them, the operating status is used to indicate the current operating condition of the refrigeration device, that is, the current operating state of the refrigeration device, including at least one of a stable operating condition, a transient operating condition, an extreme fault condition and an extreme power outage condition. Under different operating conditions, different algorithms are executed to drive the second damper to achieve different openings.

[0024] A plurality of environmental parameters are used to indicate changes in temperature and humidity inside and outside the refrigeration device, and the plurality of environmental parameters include at least one of the external ambient temperature, the internal ambient temperature, the internal ambient humidity and the number of door openings; wherein, when the environmental parameter is the external ambient temperature, it is used to indicate the external ambient temperature of the refrigeration device currently detected, and the external ambient temperature can be acquired by a monitoring element arranged outside the refrigeration device, for example, acquiring the temperature data of the external environment collected by a first temperature sensor arranged outside the refrigeration device; when the environmental parameter is the internal ambient temperature, it is used to indicate the internal ambient temperature reached inside the refrigeration device currently detected, and the internal ambient temperature can specifically further include the refrigerator compartment temperature and the freezer compartment temperature, which can be acquired by a monitoring element arranged outside the refrigeration device. The monitoring elements in different areas inside the refrigeration device collect and obtain data, for example, the temperature data of the internal environment collected by the second sensor installed inside the refrigeration device is obtained; when the environmental parameter is the internal environment humidity, it is used to indicate the internal environment humidity currently detected inside the refrigeration device. The internal environment humidity can also be collected and obtained by the monitoring elements installed in the refrigeration device, for example, a humidity sensor. The humidity data collected by the humidity sensor is the internal environment humidity; when the environmental parameter is the number of door openings, it is used to indicate the cumulative number of openings of the refrigeration device door currently detected. It can be monitored and obtained by setting a sensor element on the refrigeration device door, such as a pressure sensor, to obtain data on the number of door openings.

[0025] S103 , when the operating state indicates that the refrigeration device is in a transient operating state, normalize the plurality of environmental parameters to obtain a plurality of normalized data.

[0026] Among them, the transient operating condition refers to the condition in which the environmental parameters of the refrigeration device change suddenly and sharply, for example, the refrigeration device frequently opens the door or the internal and external temperatures rise suddenly; the transient operating condition can be judged by obtaining data collected by multiple monitoring elements. For example, when the temperature data collected by the cold storage room temperature sensor fluctuates sharply, that is, when the internal environment temperature fluctuation exceeds the preset temperature threshold, it can be judged that the refrigeration device is in a condition where the internal temperature rises suddenly; for another example, the pressure sensor provided on the door body of the refrigeration device collects data of pressure drops exceeding a preset number of times within a preset time interval. When this data is obtained, it can be judged that the refrigeration device is in a condition where the door is frequently opened.

[0027] Under this transient operating condition, the motor that triggers the second damper drives the second damper to open quickly to the maximum opening to accelerate cooling. That is, under this transient operating condition, the temperature is controlled mainly by the algorithm drive of the second damper and supplemented by the phase change passive drive of the first damper. First, multiple environmental parameters are normalized to obtain multiple normalized data, so as to map the multiple environmental parameters into the expected range and improve the stability and reliability of the subsequent second damper control.

[0028] S105 , determining a cooling score according to the plurality of normalized data and the weight coefficients corresponding to the environmental parameters.

[0029] Among them, the weight coefficient is the weight ratio of each normalized environmental parameter in the process of calculating the cooling score; accordingly, the cooling score is the sum of the products of each normalized data and their respective weight coefficients. The cooling score is used to indicate the current cooling state of the refrigeration device, specifically the real-time internal environment state achieved by the current damper control method, such as the current internal environment temperature and internal environment humidity of the refrigeration device, which can reflect the current internal state of the refrigeration device.

[0030] S107: Adjust the opening of the second damper according to the cooling score.

[0031] Among them, the opening of the second damper is positively correlated with the cooling score; that is, the cooling score can reflect the difference between the current cooling state and the target cooling state, and the target cooling state is the final cooling state inside the refrigeration device to be achieved by the damper control method; accordingly, the larger the cooling score, the greater the difference between the current cooling state and the target cooling state, and the need to increase the opening of the second damper to accelerate cooling; conversely, the smaller the cooling score, the closer the current cooling state is to the target cooling state, and the need to reduce the opening of the second damper to avoid overcooling.

[0032] In addition, it should be noted that during the opening adjustment process of the second damper, the phase change material of the first damper undergoes a volume change based on the internal ambient temperature of the refrigeration device to passively control the opening of the first damper, and will not be affected by the operating conditions of the refrigeration device. Therefore, the algorithm-driven second damper opening adjustment and the phase change-driven first damper opening adjustment work together to greatly improve the accuracy and reliability of the internal temperature control of the refrigeration device.

[0033] Specifically, if Figure 2 As shown, in step S103, the normalization process includes: S202, obtaining a first target threshold and a second target threshold corresponding to the environmental parameter; the first target threshold is the minimum value of the environmental parameter, and the second target threshold is the maximum value of the environmental parameter; S204: Obtain the normalized data corresponding to the environmental parameter according to the environmental parameter, the first target threshold, and the second target threshold.

[0034] Among them, the first target threshold and the second target threshold are both pre-configured information. In some optional embodiments, the initial range of the internal environment temperature is 2°C to 10°C, that is, the first target threshold corresponding to the internal environment temperature is 2°C, and the corresponding second target threshold is 10°C; the target range of the internal environment humidity is 40% to 90%, that is, the first target threshold corresponding to the internal environment humidity is 40%, and the corresponding second target threshold is 90%; the target range of the number of door openings is 0 to 30 times, that is, the first target threshold corresponding to the number of door openings is 0 times, and the corresponding second target threshold is 30 times; the target range of the external environment temperature is 10°C to 32°C, that is, the first target threshold corresponding to the external environment temperature is 10°C, and the corresponding second target threshold is 32°C.

[0035] In step S204, the difference between the current environmental parameter and the first target threshold, and the difference between the second target threshold and the first target threshold are calculated to obtain normalized data. Satisfies the following formula:

[0036] in, is the normalized data corresponding to the environmental parameters, is the currently obtained environment parameter, is the first target threshold, is the second target threshold.

[0037] In addition, the initial range of the internal ambient temperature can be updated according to the range of the historical internal ambient temperature recorded during the historical operation of the refrigeration device, and the range of the historical internal ambient temperature can be used as the initial range of the internal ambient temperature during the current normalization process to further improve the control accuracy and control reliability.

[0038] Specifically, if Figure 3 As shown, before determining the cooling score according to the plurality of normalized data and the weight coefficients corresponding to the environmental parameters, the method includes: S301, obtaining the initial weight coefficient corresponding to each of the environmental parameters; S303: Dynamically weight the initial weight coefficients according to the environmental parameters to obtain the weight coefficients corresponding to the environmental parameters.

[0039] Among them, each initial weight coefficient is pre-configured information, and the initial weight coefficient includes at least one of the initial external environment temperature coefficient, the initial internal environment temperature coefficient, the initial internal environment humidity coefficient and the initial door opening coefficient. In some optional embodiments, the initial internal environment temperature coefficient The initial internal environment humidity coefficient is 0.3-0.5 0.2~0.4, initial door opening coefficient The initial external environment temperature coefficient is 0.15~0.29 is 0.01~0.1; it can be understood that the initial internal environment temperature coefficient It can be any value between 0.3 and 0.5, the initial internal environment humidity coefficient It can be any value between 0.2 and 0.4, the initial door opening coefficient It can be any value between 0.15 and 0.29. The initial external environment temperature coefficient It can be any point value between 0.01 and 0.1, which will not be enumerated here.

[0040] The weight coefficient is associated with the environmental parameters. When different environmental parameters are monitored, the corresponding weight coefficient is also different. The initial weight coefficient is dynamically redistributed according to the environmental parameters to obtain various weight coefficients to improve the accuracy and reliability of subsequent calculation of the cooling score and control of the second damper opening.

[0041] Specifically, the weight coefficient includes at least one of the external environment temperature coefficient, the internal environment temperature coefficient, the internal environment humidity coefficient and the door opening coefficient; Figure 4 As shown, in step S303, the weight allocation includes: S402, when the internal environment temperature is lower than a first preset temperature, adjusting the initial internal environment temperature coefficient to a first coefficient, and using the first coefficient as the internal environment temperature coefficient; S404, when the internal environment temperature is greater than or equal to a second preset temperature, adjusting the initial internal environment temperature coefficient to a second coefficient, and using the second coefficient as the internal environment temperature coefficient; S406, when the internal environment temperature is greater than or equal to the first preset temperature and less than the second preset temperature, using the initial internal environment temperature coefficient as the internal environment temperature coefficient; S408, if the number of door openings is greater than or equal to a preset number, adjusting the initial door opening coefficient to a first door opening coefficient, and using the first door opening coefficient as the door opening coefficient; S410, when the number of door openings is less than a preset number, using the initial door opening coefficient as the door opening coefficient; S412, determining the external environment temperature coefficient based on the internal environment temperature coefficient, the door opening coefficient, and a first preset ratio; S414, determining the internal environment humidity coefficient based on the internal environment temperature coefficient, the door opening coefficient and a second preset ratio; the sum of the first preset ratio and the second preset ratio is 100%.

[0042] Among them, in steps S402-S406, different internal environment temperature coefficients are set according to the different monitored internal environment temperatures; when the internal environment temperature is greater than or equal to the first preset temperature and less than the second preset temperature, the initial internal environment temperature coefficient is used as the internal environment temperature coefficient for subsequent cooling score calculation; when the internal environment temperature is less than the first preset temperature, the initial internal environment temperature coefficient is lowered, and the first coefficient can be any point value less than the initial internal environment temperature coefficient, and the lowered first coefficient is used as the internal environment temperature coefficient, thereby reducing the weight of the internal environment temperature in the cooling score calculation; conversely, when the internal environment temperature is greater than or equal to the second preset temperature, the initial internal environment temperature coefficient is increased, and the second coefficient can be any point value greater than the initial internal environment temperature coefficient, and the increased second coefficient is used as the internal environment temperature coefficient, thereby increasing the weight of the internal environment temperature in the cooling score calculation.

[0043] In some exemplary embodiments, the first preset temperature is 8°C to 12°C, and the second preset temperature is 18°C ​​to 22°C; it can be understood that the first preset temperature can be any point value between 8°C and 12°C, and the second preset temperature can be any point value between 18°C ​​and 22°C, which are not enumerated here; in this way, the accuracy of the weight coefficient corresponding to the internal ambient temperature in the cooling score calculation process under different internal ambient temperatures can be effectively improved, which is conducive to improving the accuracy and reliability of the cooling score calculation.

[0044] In steps S408-S410, different door opening coefficients are set according to the different door opening times obtained. The door opening times specifically refer to the number of door openings per hour, and the preset door opening times also refer to the critical value of the door opening times per hour. When the door opening times are greater than or equal to the preset times, the initial door opening coefficient is increased, and the increased first door opening coefficient is used as the door opening coefficient. The first door opening coefficient can be any point value greater than the initial door opening coefficient to increase the weight of the door opening times in the calculation of the cooling score. When the door opening times are less than the preset times, the initial door opening coefficient can be used as the door opening coefficient to calculate the cooling score.

[0045] In some exemplary embodiments, the preset number is 3 to 6; it is understandable that the preset number can be any positive integer from 3 to 6; illustratively, the preset number can be 3, 4, 5, or 6, so as to improve the accuracy and reliability of the cooling score calculation and the subsequent second damper control under different door opening times.

[0046] For example, in one exemplary embodiment, the initial internal ambient temperature coefficient The initial internal environment humidity coefficient is 0.4 The initial door opening coefficient is 0.3. The initial external environment temperature coefficient is 0.25. is 0.05; when the internal ambient temperature is less than 10°C, the internal ambient temperature coefficient is adjusted to the first coefficient 0.1; when the internal ambient temperature is greater than or equal to 20°C, the internal ambient temperature coefficient is adjusted to the second coefficient 0.5; when the internal ambient temperature is greater than or equal to 10°C and less than 20°C, the internal ambient temperature coefficient remains at the initial internal ambient temperature coefficient 0.4; at the same time, when the number of door openings per hour is greater than or equal to 4 times, the first door opening number 0.4 is used as the door opening coefficient; when the number of door openings per hour is less than 4 times, the door opening coefficient remains at the initial door opening coefficient 0.25.

[0047] The external environment temperature coefficient can be obtained based on the first coefficient, the internal environment temperature coefficient after dynamic weight allocation and the number of door openings; similarly, the internal environment humidity coefficient can be obtained based on the second coefficient, the internal environment temperature coefficient after dynamic weight allocation and the number of door openings; or, the internal environment temperature and humidity can also be determined based on the internal environment temperature coefficient after dynamic weight allocation, the number of door openings and the external environment temperature coefficient; or, the external environment temperature coefficient can be determined based on the internal environment temperature coefficient after dynamic weight allocation, the number of door openings and the internal environment temperature and humidity.

[0048] In some exemplary embodiments, the external environment temperature coefficient satisfies the following formula:

[0049] in, is the external ambient temperature coefficient, is the internal ambient temperature coefficient, is the door opening coefficient, is the first coefficient.

[0050] The internal environment humidity coefficient satisfies the following formula:

[0051] in, Internal environment humidity coefficient, is the second coefficient.

[0052] Accordingly, the cooling score Satisfies the following formula:

[0053] in, is the internal ambient temperature, is the number of door openings, is the external ambient temperature, The internal humidity.

[0054] In some exemplary embodiments, the sum of the first coefficient and the second coefficient is 100%, the first coefficient is 50% to 80%, and the second coefficient is 20% to 50%; it is understandable that the first coefficient can be any point value between 50% and 80%, and the second coefficient can be any point value between 20% and 50%, which are not enumerated here; in this way, the accuracy and reliability of the external environment temperature coefficient and the internal environment humidity coefficient are improved, thereby improving the accuracy and reliability of the cooling score and the second damper control; for example, in some specific embodiments, the first coefficient is 65% and the second coefficient is 35%.

[0055] Specifically, if Figure 5 As shown, adjusting the opening of the second damper according to the cooling score includes: S501, when the cooling score is less than a first preset score, controlling the second damper to close; S503: If the cooling score is greater than or equal to a first preset score and less than a second preset score, control the opening of the second damper to a first target opening; the first target opening is positively correlated with the cooling score; S505 : When the cooling score is greater than or equal to a second preset score, controlling the opening of the second damper to be a second target opening.

[0056] In this step, the abstract cooling score is converted into a specific opening and closing angle of the second damper. The cooling score is strongly correlated with the opening of the second damper. The cold air in the refrigeration device is blown out through the first damper and the second damper by the fan. When the opening of the second damper is controllable, the higher the internal ambient temperature, the more cold air is needed, and the larger the opening of the second damper is controlled; conversely, the lower the internal ambient temperature, the less cold air is needed, and the smaller the opening of the second damper is controlled.

[0057] When the cooling score is less than the first preset score, it means that the internal ambient temperature inside the refrigeration device is already low in the current state. In this case, the opening of the second damper can be controlled to 0°, that is, the second damper is closed, and only the first damper driven by the phase change is used for blowing air for cooling, thereby saving the energy consumption required to control the second damper.

[0058] When the cooling score is greater than or equal to the first preset score and less than the second preset score, it indicates that the internal ambient temperature of the refrigeration device has been reduced to a certain extent in the current cooling state, but further cooling is still required to accelerate the cooling effect. In this case, the opening of the second damper is controlled to be the first target opening, and the first target opening satisfies the following formula:

[0059] in, is the first target opening, Score refrigeration.

[0060] When the cooling score is greater than or equal to the second preset score, it means that the internal ambient temperature inside the current refrigeration device is high. For example, when the refrigeration device is started or the door is opened, rapid cooling is required. In this case, the opening of the second damper is controlled to be the second target opening. The second target opening is the maximum opening of the second damper, which can be 90°.

[0061] Among them, the first preset score is 0.1~0.3, and the second preset score is 0.9~1; it can be understood that the first preset score can be any point value between 0.1~0.3, and the second preset score can be any point value between 0.9~1, which are no longer enumerated here; in this way, graded control is performed through different cooling scores, which can effectively improve the temperature control accuracy on the one hand, and save energy and reduce cold air waste on the other hand; for example, in a specific embodiment, the first preset score is 0.2, and the second preset score is 1.

[0062] Specifically, after obtaining the operating state of the refrigeration device and a plurality of environmental parameters, the phase change material of the first damper undergoes a volume change based on the internal ambient temperature of the refrigeration device to passively control the opening of the first damper; Figure 6 As shown, the method further includes: S602: When the operating state indicates that the refrigeration device is in a stable operating state, controlling the opening of the second damper to a first preset opening; S604: When the operating state indicates that the refrigeration device is in an extreme fault condition, control the opening of the second damper to a second preset opening.

[0063] Among them, the stable operating condition refers to the state in which the door body of the refrigeration device is in a closed state and the internal temperature and humidity are stable. The stable operating condition can be judged by obtaining monitoring data collected by multiple sensor elements. For example, within a preset time interval, the fluctuation range of the monitored internal environment temperature is less than the preset temperature fluctuation range, then it can be determined that the internal environment temperature inside the current refrigeration device is stable. At the same time, it is monitored that the data collected by the pressure sensor installed at the door body hardly changes within the preset time interval, then it can be determined that the door body of the current refrigeration device is in a closed state, and then it can be determined that the current stable operating condition is in combination with the closed state of the door body and the stable state of the internal environment temperature; under this stable operating condition, the first damper driven by the phase change material is mainly used, and the second damper driven by the algorithm is auxiliary. At this time, the second damper can remain closed or slightly open.

[0064] Specifically, the first preset opening is 0°~8°; it can be understood that the first preset opening can be any point value between 0°~8°; exemplarily, the first preset opening can be 0°, 2°, 4°, 5°, 6°, 8°, etc.; within the first preset opening range, the second damper is in a closed or slightly open state, mainly relying on the phase change material of the first damper to automatically adjust the opening of the first damper according to the current ambient temperature in the store, thereby maintaining the cooling or heating balance and saving energy consumption.

[0065] Specifically, an extreme fault condition refers to a situation where at least one component in the refrigeration device fails, for example, a first temperature sensor fails. In this case, taking the first temperature sensor as an example, it can be determined that the refrigeration device is in an extreme fault condition by the following steps: Acquire status information of the first temperature sensor; the status information is used to indicate the current working state of the first temperature sensor, and the working state of the first temperature sensor includes an operating state and a fault state; If the status information indicates that the first temperature sensor is in a fault state, determining that the refrigeration device is in an extreme fault condition, and executing step S604; When the status information indicates that the temperature sensor is in an operating state, step S103 or step S602 is executed.

[0066] Under extreme fault conditions, the first damper is still affected by the internal ambient temperature, causing the phase change material to change volume, achieving passive adjustment of the first damper opening, while the second damper opening is controlled to a fixed value, i.e., the second preset opening, to maintain internal ambient temperature balance.

[0067] Specifically, the second preset opening is 20°~40°; it can be understood that the second preset opening can be any point value between 20°~40°; exemplarily, the second preset opening can be 20°, 25°, 30°, 35°, 40°, etc.; within the second preset opening range, it can effectively maintain the internal environment temperature balance under extreme fault conditions, maintain the cooling effect, and avoid waste of cold air.

[0068] Specifically, when the operating condition indicates that the refrigeration device is in an extreme power-off condition, the opening of the second damper stops at the current opening, and the phase change material of the first damper changes in volume based on the internal ambient temperature of the refrigeration device to passively control the opening of the first damper; the power-off extreme condition refers to a state in which the refrigeration device is disconnected from the power supply. At this time, the first damper and the second damper cannot be actively controlled, and the second damper stops at the current opening when the power is disconnected, that is, the second damper stops moving and the current opening remains unchanged; the phase change material of the first damper is not affected by the power outage, but will be affected by the change in the internal ambient temperature of the refrigeration device in the power-off state. In the power-off state, the internal ambient temperature of the refrigeration device will also change, so that the phase change material of the first damper eventually changes in volume to passively change the opening of the first damper.

[0069] Furthermore, it should be noted that under transient operating conditions, stable operating conditions, extreme fault conditions, and extreme power outage conditions, the opening of the first damper is passively controlled only by the phase change material. The volume change generated by the current internal ambient temperature of the refrigeration unit changes the opening of the first damper, thereby changing the opening of the first damper. This allows the phase change-driven first damper to be primarily used in long-term stable operating conditions. For example, when the refrigeration unit continues to cool in the off state, the opening of the first damper is passively adjusted by the phase change material to passively adjust the air volume, reducing energy consumption and achieving passive coarse adjustment of the damper opening. The algorithm-driven second damper, on the other hand, is primarily used in transient operating conditions, such as when the refrigeration unit door is opened or when the external ambient temperature suddenly changes. The algorithm rapidly drives the opening of the second damper to adjust and restore temperature equilibrium, achieving active fine-tuning. The two work together to achieve hybrid drive of multiple environmental parameter feedback and phase change material, greatly improving the control accuracy of the damper control method, improving the accuracy and stability of temperature and humidity control within the refrigeration unit, slowing the loss of moisture and nutrients in food, avoiding waste of cold air, and reducing the frequent start-stop of the compressor, thereby reducing energy consumption.
