[0024] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] Refrigeration control is the main factor in maintaining the quality of fresh food during storage. Under low temperature conditions such as refrigeration, the enzyme activity in the food is reduced, the microbial reproduction rate is reduced, and the oxidation liquid of the food tissue is slowed down, so its shelf life will be significantly extended. At present, the most commonly used methods are refrigeration and freezing. With the increase in user demand for high-quality food and technological progress, technologies such as ice temperature are called technical hotspots, and the scope of use of low temperature is gradually refined. Ice temperature and ultra-ice temperature preservation technology came into being and gradually became a research hotspot. In the development technology route of refrigerators, it has experienced a technical upgrade from direct cooling to air cooling, which has improved system efficiency. Therefore, air-cooled refrigerators are the mainstream technology in the industry.

[0026] In the related art, a constant temperature sensor at the rear, such as a thermistor sensor (Negative Temperature Coefficient, NTC), is used to control the cooling capacity required for the entire storage space, but it is impossible to determine the real-time surface temperature of the food in the storage space to accurately match the cooling capacity, which is not conducive to the preservation of food, especially food, aquatic and other animal food. To this end, the embodiments of the present application provide a refrigeration control method, device, electronic device and storage medium to adjust the cooling capacity of the refrigeration device based on the surface temperature value of the newly placed food, thereby improving the accuracy of refrigeration adjustment.

[0027] The following describes the refrigeration control method, device, electronic device and storage medium of the embodiments of the present application with reference to the accompanying drawings.

[0028] Figure 1 A schematic flow chart of a refrigeration control method provided in an embodiment of the present application.

[0029] As an implementation manner, the refrigeration control method of the embodiment of the present application can be configured in a refrigeration control device, and the refrigeration control device can be applied to any electronic device so that the electronic device can perform a refrigeration capacity adjustment function.

[0030] The electronic device may be any device with refrigeration capability, such as a refrigerator, a freezer or a freezer.

[0031] like Figure 1 As shown, the method may include the following steps:

[0032] Step 101: in response to a first food being placed in a storage space of a refrigeration device, surface temperature information of the first food is determined.

[0033] The storage space is used to cool the stored food to ice temperature or super ice temperature. Ice temperature or super ice temperature refers to the state where the food is at or below freezing point but not frozen. The storage space is, for example, a constant temperature drawer in a refrigerator. As an implementation method, the main components include a sealed insulation barrel, a drawer body, an NTC sensor module, a pyroelectric sensor module, an independent damper, a sealing strip, etc., and the sealing strip, the drawer body, and the sealed insulation barrel form a closed temperature-changing space.

[0034] Among them, the first ingredient usually refers to fresh ingredients, such as animal ingredients, aquatic ingredients, etc.

[0035] In the embodiment of the present application, a pyroelectric sensor is installed in the storage space to detect the surface temperature of the food in the storage space. The pyroelectric sensor is, for example, an infrared sensor. The pyroelectric sensor is very sensitive to the temperature changes of the surrounding objects, and the temperature sensing accuracy is 0.01°C.

[0036] The surface temperature information may be the absolute temperature of the first food obtained through detection, or the temperature change of the first food, for example, the temperature change corresponding to two adjacent detections.

[0037] Step 102: adjusting the refrigeration capacity of the refrigeration device according to the surface temperature information of the first food.

[0038] In the embodiment of the present application, the refrigeration capacity required to cool the first food can be determined based on the surface temperature information of the first food, thereby achieving precise adjustment of the refrigeration capacity of the refrigeration device and improving the accuracy of the adjustment.

[0039] Among them, as an implementation method, the surface temperature information includes the absolute temperature of the surface of the first food, and the absolute temperature is obtained by measuring the first food based on the infrared temperature measurement principle by a pyroelectric sensor. The required cooling capacity is determined according to the surface temperature value of the first food, wherein the surface temperature value of the first food is positively correlated with the required cooling capacity, so that the cooling capacity is controlled according to the required cooling capacity, thereby improving the accuracy of the cooling capacity control, achieving a maximized preservation effect, and enabling users to obtain better preservation quality.

[0040] As another implementation method, the surface temperature information includes the relative temperature of the surface of the first food, which is the difference between the temperature of the first food measured by the pyroelectric sensor at the current moment and the temperature of the first food measured by the pyroelectric sensor at the previous moment. According to the difference, the required refrigeration capacity is determined, thereby achieving accurate refrigeration control and maximizing the preservation effect, so that users can obtain better preservation quality.

[0041] Among them, controlling the refrigeration device to perform refrigeration, as an implementation method, can increase the cooling capacity generated by the evaporator, and the cooling capacity can be adjusted by the air supply temperature and the wind speed of the air supply. Among them, the lower the air supply temperature, the more cooling capacity the air volume passing through per unit time carries, and the greater the wind speed, the more air volume passing through per unit time, and the more cooling capacity it carries, that is, increasing the cooling capacity from the source. As another implementation method, the cooling capacity at the source can also remain unchanged, and the amount of cooling capacity entering can be controlled by the control device, for example, by controlling the opening angle of the damper to adjust the cooling capacity.

[0042] In the refrigeration control method of the embodiment of the present application, in response to the first food being placed in the storage space of the refrigeration device, the surface temperature information of the first food is determined, and the refrigeration capacity of the refrigeration device is adjusted according to the surface temperature information of the first food, so as to determine the required cooling capacity based on the surface temperature information of the placed first food, and accurately adjust the cooling capacity based on the required cooling capacity, thereby improving the preservation effect of the food and allowing users to obtain better preservation quality.

[0043] Based on the above embodiments, Figure 2 A flow chart of another refrigeration control method provided in an embodiment of the present application is shown as follows: Figure 2 As shown, the method comprises the following steps:

[0044] Step 201: in response to a first food being placed in a storage space of a refrigeration device, surface temperature information of the first food is determined.

[0045] Among them, step 201 can refer to the relevant explanations in the above-mentioned embodiment, and the principle is the same, which will not be repeated here.

[0046] In the embodiment of the present application, the surface temperature information includes the surface temperature value as an example for description.

[0047] Step 202: determining a first operating parameter of the damper according to a surface temperature value of the first food material.

[0048] In one implementation of the embodiment of the present application, a corresponding first cooling rate is determined according to the surface temperature value of the first food, and a first operating parameter of the damper is determined according to the first cooling rate, wherein the first cooling rate is positively correlated with the surface temperature value of the first food.

[0049] In the embodiment of the present application, the surface temperature value of the first food material is positively correlated with the first cooling rate, that is, the higher the surface temperature value of the first food material, the higher the corresponding first cooling rate, that is, when the surface temperature value of the first food material is high, a faster cooling rate is used for cooling, and when the surface temperature value of the first food material is reduced, a reduced cooling rate is used for cooling, so that when the surface temperature value of the first food material is different, cooling treatment is performed based on different cooling rates, that is, the initial cooling rate can be faster, so that the temperature of the food material can be quickly reduced to prevent the reproduction of microorganisms. As the temperature of the food material is reduced, the corresponding cooling rate must also be reduced, so that the food material enters the ice temperature acclimation stage and adapts to the ice temperature. At the same time, in order to resist the low temperature, the inside of the food material produces an unfreezing liquid to resist the low temperature, and the internal water structure and enzyme activity are reduced to achieve non-freezing and achieve the best preservation effect.

[0050] In the refrigeration device, different cooling speeds can be achieved by controlling the operating parameters of the damper. In order to identify the operating parameters of the damper in different scenarios, the operating parameters of the damper in this embodiment are referred to as first operating parameters, wherein the first operating parameters of the damper include the opening angle of the damper and / or the air supply speed of the damper, wherein the air supply speed of the damper refers to the wind speed of the cold air entering through the damper. The opening angle is positively correlated with the first cooling speed, that is, the larger the opening angle, the more cold air enters and the higher the first cooling speed, the smaller the opening angle, the less cold air enters and the lower the first cooling speed. The air supply speed is also positively correlated with the first cooling speed, that is, the faster the air supply speed, the more cold air enters and the higher the first cooling speed, the slower the air supply speed, the less cold air enters and the slower the first cooling speed.

[0051] Here, the opening angle of the damper is used as an example for explanation. In one scenario, the supply temperature of the cold air input into the storage space is constant, and the speed of the refrigeration fan is constant. The larger the opening angle of the damper, the more cold air enters, the greater the coldness carried, and the greater the coldness, the higher the first cooling speed. On the contrary, the smaller the opening angle of the damper, the less cold air enters, the smaller the coldness carried, and the smaller the coldness, the lower the first cooling speed. The corresponding relationship between the first cooling speed and the operating parameters of the damper is obtained by measuring the coldness input by the damper under various operating parameters according to the coldness required for the first cooling speed. As an implementation method, for example, the supply air temperature of the cold air input into the storage space is -26°C, the speed of the refrigeration fan is constant, and the food in the storage space is cooled according to the first cooling speed. By controlling the damper to hover at various opening angles, the cold amount entering the damper is tested, thereby obtaining the corresponding relationship between the damper opening angle and the input cold amount. Since the cold amount and the first cooling speed also have a corresponding relationship, the corresponding relationship between the damper opening angle and the first cooling speed can be determined through testing. Similarly, the corresponding relationship between the damper's air supply speed and the first cooling speed can be determined by testing.

[0052] Similarly, the corresponding relationship between the operating parameters of the damper and different cooling speeds can be determined.

[0053] Among them, the amount of cold input into the storage space is positively correlated with the air inlet area of ​​the damper. The opening angle of the damper can be set to 0 to 90°, so the air inlet area of ​​the damper can be divided into 90 equal parts, that is, different 90 equal parts of cold capacity, which can be controlled by a proportional-integral-derivative controller (PID) to achieve the hovering of the damper at any angle.

[0054] Step 203: Controlling the operation of the damper according to the first operating parameter of the damper to adjust the cooling capacity of the refrigeration device.

[0055] The operation of the damper is controlled according to the first operating parameter of the damper, that is, the damper is controlled to operate with the first operating parameter.

[0056] Among them, step 203 can refer to the relevant explanations in the above-mentioned embodiment, and the principle is the same, which will not be repeated here.

[0057] Step 204, continue to monitor the surface temperature of the first food.

[0058] In an embodiment of the present application, while controlling the operation of the damper according to the first operating parameter of the damper, the surface temperature value of the first food continues to be monitored by the pyroelectric sensor, so as to achieve step-by-step adjustment of the cooling capacity after the surface temperature value of the first food decreases, that is, to achieve step-by-step temperature control.

[0059] Step 205: in response to the monitored surface temperature value of the first food material dropping from the first temperature range to the second temperature range, switching the cooling speed from the first cooling speed to the second cooling speed.

[0060] The first temperature range corresponds to a first cooling rate, and the second temperature range corresponds to a second cooling rate.

[0061] Step 206, determining a second operating parameter of the damper according to the second cooling speed.

[0062] The "second" in the second operating parameter is an identifier of the operating parameter of the damper corresponding to different cooling speeds. When the damper operates under the second operating parameter, the cooling amount input to the storage space is less than the cooling amount input to the storage space when the damper operates under the first operating parameter.

[0063] In one implementation of the embodiment of the present application, in order to achieve step-by-step adjustment of the cooling capacity, that is, to achieve step-by-step temperature control, while controlling the operation of the damper according to the determined first operating parameter of the damper to adjust the cooling capacity of the refrigeration device, the surface temperature value of the first food can be monitored by a pyroelectric sensor. If the surface temperature value of the first food decreases, the cooling speed will be switched to a second low cooling speed, which is less than the first cooling speed. That is, the damper operation is controlled based on the second operating parameter of the damper corresponding to the second low cooling speed to reduce the input cooling capacity, so as to continue to adjust the cooling capacity of the refrigeration device and achieve step-by-step temperature control.

[0064] As an example, the first cooling rate is 1 degree Celsius per hour, and the second cooling rate is 0.5 to 1 degree Celsius per 24 hours.

[0065] It should be noted that, in the embodiment of the present application, step cooling including two stages is used as an example for explanation. In actual scenarios, step cooling can be divided into multiple sections. The cooling speed is switched according to the monitored surface temperature value of the first food, so that different cooling speeds are used for cooling in different stages to improve the insurance effect of the food.

[0066] As an example, the cooling rate can be set to multiple stages, for example, 4 stages. If the surface temperature of the first food is greater than 20°C, the corresponding cooling rate is 3 to 5 degrees Celsius per hour (3 to 5°C) / h; if the surface temperature of the first food is between 5 and 20°C, the corresponding cooling rate is 1 to 3 degrees Celsius per hour, that is, (1 to 3°C) / h; if the surface temperature of the first food is between 0 and 5°C, the corresponding cooling rate is 1 degree Celsius per hour, that is, 1°C / h; if the surface temperature of the first food is between 0 and -3°C, the corresponding cooling rate is 0.5 to 1 degree Celsius per 24 hours, that is, (0.5 to 1°C) / 24h. Therefore, the first cooling rate and the second cooling rate are in any of the following cooling ranges:

[0067] Cool down by 3 to 5 degrees Celsius per hour;

[0068] Cool down by 1 to 3 degrees Celsius per hour;

[0069] Cool down 1 degree Celsius per hour;

[0070] The temperature drops by 0.5 to 1 degree Celsius every 24 hours.

[0071] The second cooling rate is lower than the first cooling rate.

[0072] In the embodiment of the present application, during the cooling process of the first food, the cooling rate is adjusted based on the change in the surface temperature value of the first food, so that during the cooling process of the first food, the cooling rate can be faster in the early stage, so that the temperature of the food can be quickly reduced to prevent the reproduction of microorganisms. Subsequently, as the surface temperature value of the first food decreases, the cooling rate used should be slower, so that the food enters the ice temperature acclimation stage and adapts to the ice temperature. At the same time, in order to resist the low temperature, the interior of the food produces non-freezing liquid to resist the low temperature, and the internal water structure and enzyme activity are reduced to prevent freezing and achieve the best preservation effect.

[0073] In the present application, the meat cooling period is divided into multiple sections from refrigeration to the end point of ultra-freezing temperature control. The cooling in each period corresponds to a set temperature, and the cooling cycle of each section is a set value, for example, 12 hours or 24 hours, forming a stepped temperature control method to improve the control effect.

[0074] Step 207: Control the operation of the damper according to the second operating parameter of the damper to adjust the cooling capacity of the refrigeration device.

[0075] The operation of the damper is controlled according to the second operating parameter of the damper, that is, the damper is controlled to operate with the second operating parameter.

[0076] Among them, step 207 can refer to the relevant explanations in the aforementioned embodiment of controlling the operation of the damper according to the first operating parameter of the damper to adjust the cooling capacity of the refrigeration device. The principle is the same and will not be repeated here.

[0077] Step 208 , in response to monitoring that the surface temperature of the first food drops to within the target temperature range set for the storage space, controlling the damper to close to stop adjusting the cooling capacity of the refrigeration device.

[0078] In the related art, refrigeration control is mainly used to cool the food to zero degrees or a slightly frozen state. Although the former is at 0 degrees, it will not freeze due to temperature fluctuations and the freezing point of the food, but it also brings a shorter shelf life; the latter is usually below -4°C. Although a relatively long shelf life is achieved, the food has been frozen, and the color and texture have changed significantly. Therefore, in order to improve the preservation effect, in the embodiment of the present application, the target temperature range of the storage space is set to -4°C to -0.1°C, so that the food is at ice temperature or super ice temperature, thereby improving the preservation effect of the food.

[0079] In one implementation of the embodiment of the present application, during the process of cooling the first food using the second cooling rate, the surface temperature value of the first food will continue to be monitored by the pyroelectric sensor. When it is monitored that the surface temperature value of the first food has dropped to within the target temperature range, the damper is controlled to close to stop adjusting the refrigeration capacity of the storage space in the refrigeration device, that is, to stop allowing cold air to enter the storage space through the damper, so as to keep the food at an ice temperature or super-ice temperature state, that is, to keep the food below the freezing point but not frozen, thereby achieving a maximized preservation effect and allowing users to obtain better preservation quality.

[0080] In the refrigeration control method of the embodiment of the present application, a corresponding first cooling speed is determined according to the surface temperature value of the first food, and a first operating parameter of the damper is determined according to the first cooling speed, wherein the first cooling speed is positively correlated with the surface temperature value of the first food, so as to achieve the determination of the corresponding first cooling speed based on the surface temperature value of the first food, so that when the surface temperature value is high, a higher cooling speed is adopted, and when the surface temperature value is low, a lower cooling speed is adopted for cooling, and then, according to the correspondence between the first cooling speed and the first operating parameter of the damper, a matching first operating parameter is determined to adjust the refrigeration amount entering the storage space, so as to achieve precise refrigeration adjustment, improve the refrigeration effect, and allow the food to enter an ice temperature or super ice temperature state, thereby improving the precise temperature control of the food.

[0081] Based on the above embodiments, when determining whether it is possible to stop adjusting the refrigeration capacity of the storage space of the refrigeration device, as another implementation method, an NTC sensor provided in the storage space of the refrigeration device can be used to collect the spatial temperature of the storage space. When the spatial temperature of the storage space is within the target temperature range, the damper is controlled to close to stop adjusting the refrigeration capacity of the storage space in the refrigeration device, that is, stop allowing cold air to enter the storage space through the damper, so as to keep the food in an ice temperature or super ice temperature state, that is, keep the food in a state below the freezing point but not frozen, thereby achieving a maximized preservation effect and allowing users to obtain better preservation quality.

[0082] In actual scenarios, when the first ingredient is placed in the storage space, the second ingredient may have already been stored, and the temperature of the second ingredient may have been within the target temperature range, and may be the lower limit of the target temperature range, that is, the second ingredient is in an unstable state. At this time, if the newly placed first ingredient releases heat due to its high temperature, causing the temperature in the storage space to rise, the temperature collected by the NTC sensor will continue to drop, thereby destroying the original super-freezing temperature state of the second ingredient, and the second ingredient will enter a frozen state, destroying the texture of the second ingredient. Therefore, in order to reduce the occurrence of the destruction of the texture of the second food, the present application monitors the surface temperature value of the second ingredient based on a pyroelectric sensor to improve the accuracy of refrigeration control. Based on the above embodiments, Figure 3 A flow chart of another refrigeration control method provided in an embodiment of the present application is shown as follows: Figure 3 As shown, the method comprises the following steps:

[0083] Step 301: in response to a first food being placed in a storage space of a refrigeration device, surface temperature information of the first food is determined.

[0084] As an example, Figure 4 A schematic diagram of food surface temperature measurement provided in an embodiment of the present application, wherein a pyroelectric sensor A is provided in the storage space, wherein the pyroelectric sensor may be one or more. When there are multiple food ingredients in the storage space, multiple pyroelectric sensors are used to monitor them separately to improve the monitoring accuracy, or one pyroelectric sensor is used to monitor them separately to reduce the cost.

[0085] Step 302: determining a first operating parameter of the damper according to the surface temperature value of the first food material.

[0086] In the embodiment of the present application, the surface temperature information includes the surface temperature value as an example for description.

[0087] Among them, step 301 and step 302 can refer to the relevant explanations in the aforementioned embodiments, and the principles are the same, so they will not be repeated here.

[0088] Step 303: monitor the surface temperature of the second food in the storage space.

[0089] The second food material is the food material that has been stored in the storage space of the refrigeration device before the first food material is put into the refrigeration device.

[0090] In the embodiment of the present application, a pyroelectric sensor provided in the storage space is used to monitor the surface temperature value of the second food. Specifically, the temperature detection can be performed according to a set cycle. The specific cycle duration can be set based on demand and is not limited in the present embodiment.

[0091] Step 304 , in response to the surface temperature value of the second food being greater than the lower limit of the set target temperature range, controlling the operation of the damper according to the first operating parameter of the damper to adjust the cooling capacity of the refrigeration device.

[0092] In the embodiment of the present application, if the surface temperature value of the second food is greater than the lower limit of the set target temperature range, that is, the second food is not at the critical point of super-freezing temperature, the second food is not in a state of being easily frozen, and the damper operation can be controlled according to the currently determined first operating parameter to adjust the cooling capacity of the refrigeration device. Among them, determining the first operating parameter, and controlling the damper operation according to the first operating parameter to adjust the cooling capacity of the refrigeration device can refer to the relevant explanations in the above-mentioned embodiment, the principle is the same, and it will not be repeated here.

[0093] Step 305 : in response to the surface temperature value of the second food being less than or equal to the lower limit of the target temperature range, maintaining the third operating parameter of the damper to control the operation of the damper.

[0094] Among them, the third operating parameter is the operating parameter of the damper before the first ingredient is put in.

[0095] In the embodiment of the present application, if the surface temperature value of the second food is less than or equal to the lower limit of the target temperature range, the second food is at a critical point of super-freezing temperature, that is, the second food is in an unstable state that is easy to freeze. In this case, the damper operation cannot be controlled according to the first operating parameter, but the control logic used before the first food is put in is continued to be used for control, that is, the third operating parameter of the damper before the first food is put in is continued to be used to control the damper operation, so as to adjust the refrigeration capacity in the storage space of the refrigeration device, thereby reducing the probability of the old second food freezing. Since the temperature of the storage space is relatively low, and the temperature of the storage space will rise due to the high temperature of the first food, the first food will reduce the growth of bacteria in a low temperature environment. Since the temperature of the space will rise, refrigeration can be carried out quickly. Therefore, the overall preservation of the first food will not be affected, thereby improving the accuracy of refrigeration control.

[0096] Step 306 , in response to monitoring that the surface temperature of the second food is greater than the lower limit of the target temperature range, controlling the operation of the damper using the first operating parameter.

[0097] In the embodiment of the present application, while using the third operating parameter of the damper to control the operation of the damper before the first food is placed in, and adjusting the refrigeration capacity in the storage space of the refrigeration device, the surface temperature value of the second food continues to be monitored. If the monitored surface temperature value of the second food is greater than the lower limit of the target temperature range, the first operating parameter is used to control the operation of the damper to achieve cooling of the first food.

[0098] Furthermore, in order to improve the accuracy of control, when the monitored surface temperature value of the second food is greater than the lower limit of the target temperature range, the surface temperature value of the first food is re-detected, and the operating parameters of the damper are re-determined based on the surface temperature value of the first food obtained by the re-detection. The operation of the damper is controlled to adjust the cooling capacity of the refrigeration device, thereby improving the accuracy of determining the operating parameters of the damper, thereby improving the accuracy of refrigeration control. The determination method can refer to the aforementioned determination method of the first operating parameter, and the principle is the same, which will not be repeated here.

[0099] Step 307: in response to monitoring that the surface temperature of the first food drops to within the target temperature range set for the storage space, the damper is controlled to close to stop adjusting the cooling capacity of the refrigeration device.

[0100] Among them, step 307 can refer to the relevant explanations in the above-mentioned embodiment, and the principle is the same, which will not be repeated here.

[0101] It should be noted that during the entire step cooling process, in order to reduce the occurrence of destruction of the texture of the second food material, the present application periodically monitors the surface temperature value of the second food material based on the pyroelectric sensor to improve the accuracy of refrigeration control, which will not be described in detail in the embodiments of the present application.

[0102] In the refrigeration control method of the embodiment of the present application, the temperatures of the first food and the second food are detected by a pyroelectric sensor. If the temperature of the second food is in an unstable state, the original refrigeration logic is maintained for refrigeration control. If the temperature of the second food is not in an unstable state, the first operating parameter of the damper determined by the surface temperature of the first food is used to control the operation of the damper to adjust the refrigeration capacity of the refrigeration device. At the same time, in the process of refrigeration control based on the surface temperature of the first food, step cooling is performed based on a plurality of pre-set cooling speeds to achieve precise refrigeration control, ensuring that the first food is cooled quickly at the beginning of the cooling stage, and then cooled slowly, so that the food enters the ice temperature acclimation stage and adapts to the ice temperature. At the same time, in order to combat the low temperature, the food produces an unfreezing liquid to combat the low temperature, and the internal water structure and enzyme activity are reduced to prevent freezing and achieve the best preservation effect.

[0103] In order to implement the above embodiment, the embodiment of the present application also proposes a refrigeration control device.

[0106] A determination module 51, configured to determine surface temperature information of a first food in response to a first food being placed in a storage space of a refrigeration device;

[0107] The control module 52 is used to adjust the refrigeration capacity of the refrigeration device according to the surface temperature information of the first food.

[0108] Further, in an implementation of the embodiment of the present application, the surface temperature information includes a surface temperature value, and the control module 52 is further configured to:

[0109] determining a first operating parameter of the air door according to the surface temperature value of the first food;

[0110] The operation of the damper is controlled according to the first operating parameter of the damper to adjust the cooling capacity of the refrigeration device.

[0111] In one implementation of the embodiment of the present application, the control module 52 is further configured to:

[0112] Determining a corresponding first cooling speed according to the surface temperature value of the first food;

[0113] determining a first operating parameter of the damper according to the first cooling speed;

[0114] Wherein, the first cooling rate is positively correlated with the surface temperature value of the first food.

[0115] In an implementation of the embodiment of the present application, the first operating parameter of the damper includes an opening angle of the damper and / or an air supply speed of the damper;

[0116] The opening angle is positively correlated with the first cooling speed;

[0117] The air supply speed is positively correlated with the first cooling speed.

[0118] In one implementation of the embodiment of the present application, the correspondence between the first cooling rate and the first operating parameter of the damper is obtained by measuring the cooling capacity input by the damper under various operating parameters according to the cooling capacity required by the first cooling rate.

[0119] In one implementation of the embodiment of the present application, the device further includes:

[0120] The monitoring module is used to monitor the surface temperature of the first food.

[0121] A switching module is used to switch the cooling speed from the first cooling speed to the second cooling speed in response to the monitored surface temperature value of the first food dropping from a first temperature range to a second temperature range; wherein the first temperature range corresponds to the first cooling speed, and the second temperature range corresponds to the second cooling speed.

[0122] The determination module 51 is further configured to determine a second operating parameter of the damper according to the second cooling speed.

[0123] In an implementation of the embodiment of the present application, the first cooling rate and the second cooling rate are in any one of the following cooling ranges, and the second cooling rate is less than the first cooling rate;

[0124] Cool down by 3 to 5 degrees Celsius per hour;

[0125] Cool down by 1 to 3 degrees Celsius per hour;

[0126] Cool down 1 degree Celsius per hour;

[0127] The temperature drops by 0.5 to 1 degree Celsius every 24 hours.

[0128] In one implementation of the embodiment of the present application, the control module 52 is also used to control the damper to close in response to monitoring that the surface temperature value of the first food is within the target temperature range set for the storage space, so as to stop adjusting the cooling capacity of the refrigeration device.

[0129] In one implementation of the embodiment of the present application, the target temperature range set for the storage space is -4°C to -0.1°C, so that the food is at an ice temperature or super-ice temperature state.

[0130] In one implementation of the embodiment of the present application, the control module 52 is further configured to:

[0131] monitoring a surface temperature value of a second food in the storage space, wherein the second food is food that has been stored in the storage space before the first food is placed therein;

[0132] In response to the surface temperature value of the second food being greater than a lower limit of a set target temperature range, the damper is controlled to operate according to a first operating parameter of the damper to adjust the cooling capacity of the refrigeration device.

[0133] In one implementation of the embodiment of the present application, the control module 52 is further configured to:

[0134] In response to the surface temperature value of the second food being less than or equal to the lower limit of the target temperature range, maintaining the third operating parameter of the air door to control the operation of the air door; wherein the third operating parameter is the operating parameter of the air door before the first food is placed;

[0135] In response to monitoring that the surface temperature value of the second food is greater than the lower limit of the target temperature range, the damper is controlled to operate according to the first operating parameter to adjust the cooling capacity of the refrigeration device.

[0136] It should be noted that the above explanation of the method embodiment is also applicable to the device of this embodiment, and will not be repeated here.

[0137] In the refrigeration control device of the embodiment of the present application, the temperatures of the first food and the second food are detected by a pyroelectric sensor. If the temperature of the second food is in an unstable state, the original refrigeration logic is maintained for refrigeration control. If the temperature of the second food is not in an unstable state, the first operating parameter of the damper determined by the surface temperature of the first food is used to control the operation of the damper to adjust the refrigeration capacity of the refrigeration device. At the same time, in the process of refrigeration control based on the surface temperature of the first food, step cooling is performed based on a plurality of pre-set cooling speeds to achieve precise refrigeration control, ensuring that the first food is cooled quickly at the beginning of the cooling stage, and then cooled slowly, so that the food enters the ice temperature acclimation stage and adapts to the ice temperature. At the same time, in order to combat the low temperature, the food produces an anti-freezing liquid to combat the low temperature, and the internal water structure and enzyme activity are reduced to prevent freezing and achieve the best preservation effect.
