[0025] 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.

[0026] 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.

[0027] In the related art, the refrigeration control of the storage room is relatively rough and cannot achieve accurate refrigeration control. To this end, the embodiments of the present application provide a refrigeration control method, device, electronic device and storage medium to adjust the refrigeration capacity of the refrigeration device based on the change in the amount of food after the food is put in, thereby improving the accuracy of refrigeration adjustment.

[0028] 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.

[0029] Figure 1 A schematic flow chart of a refrigeration control method provided in an embodiment of the present application.

[0030] 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.

[0031] The electronic device may be any device with refrigeration capability, such as a refrigerator, a freezer or a freezer.

[0032] like Figure 1 As shown, the method may include the following steps:

[0033] Step 101, in response to a first food being placed in a storage chamber of a refrigeration device, determining a change in the food in the storage chamber.

[0034] Among them, the storage room is used to cool the stored food to ice temperature or super ice temperature. Among them, ice temperature or super ice temperature refers to the state where the food is at or below freezing point but not frozen. The storage room, for example, is a constant temperature drawer in a refrigerator. As an implementation method, the main components include a sealed insulation barrel, a drawer body, a thermistor sensor (Negative Temperature Coefficient, NTC) module, a weight sensor, a distance sensor, 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.

[0035] Among them, the first ingredient usually refers to fresh ingredients, such as animal ingredients, aquatic ingredients, etc.

[0036] The change in ingredients may be described by weight and / or volume.

[0037] As an implementation manner, the change in the amount of ingredients includes a change in the weight of the ingredients, and the weight change indicates the weight of the newly added ingredients.

[0038] As another implementation manner, the food quantity information includes a volume change of the food, and the volume change indicates the volume of the newly added food.

[0039] Step 102, controlling the refrigeration device to perform refrigeration according to the change in the amount of food in the storage room.

[0040] In the embodiment of the present application, the change in food ingredients can indicate the weight or volume of the newly added food ingredients. The greater the change in food ingredients, the greater the weight or volume of the newly added first food ingredients. The greater the change in food ingredients, the more refrigeration capacity is required in the scenario where refrigeration is required. On the contrary, the smaller the change in food ingredients, the less refrigeration capacity is required. Therefore, the refrigeration device can be controlled to perform refrigeration on demand according to the change in food ingredients in the storage room, thereby improving the accuracy of refrigeration control, thereby achieving precise temperature control of the food ingredients in the storage room and improving the preservation effect of the food ingredients.

[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 chamber of the refrigeration device, the change in the food in the storage chamber is determined, and the refrigeration device is controlled to perform refrigeration based on the change in the food in the storage chamber, so that the refrigeration capacity of the refrigeration device is adjusted based on the change in the food after the food is placed in, thereby improving the accuracy of the refrigeration adjustment, thereby achieving precise temperature control of the food and improving the preservation effect of the food.

[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 chamber of a refrigeration device, determining a change in the food in the storage chamber.

[0045] In one scenario, the change in food material includes a change in weight.

[0046] As an implementation method, a weight sensor in the storage room is used to detect the weight change of the food in the storage room.

[0047] As an example, Figure 3 A schematic diagram of weight perception provided in an embodiment of the present application, such as Figure 3 As shown, the new food in the storage room is the first food, and the original food is the food in the storage room before the first food is put into the storage room. When the user puts the new food into the storage room, that is, the tray in the sealed drawer, the weight change of the tray will be immediately sensed by the weight sensor, that is, Figure 3 As an example, the weighing sensor is set at the base of the tray. The weight sensor can determine the weight change of the food, that is, the weight of the new food, according to the difference between a first weight sensed before the new food is put in and a second weight sensed after the new food is put in.

[0048] In another scenario, the change in ingredients includes a change in volume.

[0049] As an implementation method, the volume change of the food in the storage room is detected by a distance measuring sensor in the storage room.

[0050] As an example, Figure 4 A schematic diagram of a volume change test principle provided in an embodiment of the present application, wherein the storage chamber is, for example, a constant temperature drawer in a refrigerator, such as Figure 4As shown, A is a distance measuring sensor set in the storage room, for example, a direct time-of-flight sensor (DTOF). When the direct time-of-flight sensor emits a light pulse to the food (such as animal food, including fish, seafood, meat, etc.) in the storage space (constant temperature drawer), the light pulse will be reflected by the food to obtain a reflected light pulse, and the time interval between the reflected light pulse and the emitted light pulse is measured to calculate the flight time of the light, and the distance is detected according to the flight time of the light. Specifically, the DTOF sensor uses VCSEL (vertical cavity surface emitting laser) to emit light pulses to the food from different angles. For each angle of the light pulse, the light pulse of the angle is reflected back after being irradiated on the surface of the food and received by the single photon avalanche diode SPAD. SPAD converts the received reflected light pulse into an electrical signal and records the flight time of the light pulse through the time-to-digital converter TDC. Thus, the reflected light pulses at different angles can be statistically obtained. By statistically analyzing the flight time of multiple light pulses at different angles and the reflected light pulses, the distance information of the food can be calculated. Based on the distance information of the food, the size of the food can be determined, and thus the volume of the food can be determined. Based on the volume measured before and after the new food is put in, the volume change can be determined, that is, the volume of the first newly put in food.

[0051] Step 202, obtaining a first space temperature of the storage chamber monitored after the first food is put in.

[0052] In the embodiment of the present application, the spatial temperature of the storage room is detected by an NTC temperature sensor installed in the storage room, which is referred to as the first spatial temperature for identification purposes.

[0053] As an implementation method, the spatial temperature will change after the first ingredient is put in. Usually, the first ingredient is a new ingredient that the user wants to keep fresh, and the temperature of the first ingredient is usually relatively high, for example, 15 degrees. In order to improve the accuracy of the detected spatial temperature after the first ingredient is put in, the spatial temperature of the storage room can be detected after detecting that the first ingredient has been put in for a set time, that is, after the spatial temperature stabilizes, to obtain the first spatial temperature. The first spatial temperature can be used to indicate the temperature of the first ingredient. If the first spatial temperature is high, it indicates that the temperature of the first ingredient is high, and if the first spatial temperature is low, it indicates that the temperature of the first ingredient is high.

[0054] Step 203, adjusting the amount of cold air entering the storage chamber according to the change in the food and the temperature of the first space.

[0055] In the embodiment of the present application, the change in food material indicates the weight or volume of the newly placed first food material, and the first space temperature indicates the temperature information of the newly placed first food material. Thus, based on the change in food material and the first space temperature, the first amount of cold required to cool the first food material can be determined. Thus, based on the first amount of cold required to cool the first food material, the amount of cold entering the storage chamber is adjusted, thereby realizing on-demand refrigeration control based on the change in food material and the first space temperature, and improving the accuracy of refrigeration control.

[0056] In the embodiment of the present application, the first amount of cooling required to cool the first food can be determined based on the change in the food and the temperature of the first space. The cooling amount entering the storage chamber is adjusted based on the first amount of cooling required to cool the first food, thereby achieving on-demand cooling control based on the change in the food and the temperature of the first space, thereby improving the accuracy of cooling control.

[0057] Based on the above embodiments, Figure 5 A flow chart of another refrigeration control method provided in an embodiment of the present application is shown as follows: Figure 5 As shown, the method comprises the following steps:

[0058] Step 501, in response to a first food being placed in a storage chamber of a refrigeration device, determining a change in the food in the storage chamber.

[0059] Step 502, obtaining a first spatial temperature of the storage chamber after the first food is placed therein.

[0060] Among them, step 501 and step 502 can refer to the relevant explanations in the aforementioned embodiments, and the principles are the same, so they will not be repeated here.

[0061] Step 503: Determine the first cooling amount required for the first food according to the change in the food and the temperature of the first space.

[0062] In one implementation of the embodiment of the present application, the heat capacity corresponding to the first food is determined according to the change in the food.

[0063] Among them, the change in the amount of newly added ingredients can be converted into corresponding heat capacity. As an implementation method, the heat capacity is the product of the change in the amount of ingredients, specific heat capacity and density.

[0064] In one scenario, the change in ingredients is a change in weight, which indicates the weight of the newly added ingredients. The weight of the ingredients can be calculated into the corresponding heat capacity.

[0065] Taking meat as an example of new food, the specific heat capacity of meat is about 3.55 J / g·℃; assuming that the weight of the meat tested by the weight sensor is 1000 g, the heat capacity is the product of volume, specific heat capacity and density, that is, 1000*3.55=3.55 KJ / ℃.

[0066] In another scenario, the change in ingredients is a change in volume, which indicates the volume of the newly added ingredients. The volume of the ingredients can be calculated into the corresponding heat capacity.

[0067] Taking meat as an example, the density of meat is 0.925g / cm 3 ~1.2g / cm 3 , taking the median value as about 1.1g / cm 3 , the specific heat capacity of meat is about 3.55 J / g·℃; assuming that the volume of the meat tested by the dToF sensor is 10cm*10cm*10cm, that is, 1000cm 3 , heat capacity is the product of volume, specific heat capacity and density, that is, 1000*1.1*3.55=3.95KJ / ℃.

[0068] It should be noted that, in the embodiment of the present application, the specific heat capacity can be set to a fixed value, or the corresponding specific heat capacity can be determined according to the first space temperature.

[0069] Furthermore, a first set temperature to which the first food is to be cooled is determined according to the first space temperature.

[0070] Among them, the first set temperature and the second set temperature are set temperatures for realizing step-by-step cooling, and the set temperatures at least include the first set temperature and the second set temperature.

[0071] As an implementation method, multiple set temperatures are determined based on experience to determine the cooling capacity of each cooling based on the space temperature monitored in real time, and to make refrigeration adjustments based on the corresponding cooling capacity.

[0072] As an example, it can be divided into 3 sections to achieve step cooling, and each section has a set first set temperature to be cooled to. For example, the first set temperature to be cooled to corresponding to the first stage is 6 degrees, the first set temperature to be cooled to corresponding to the second stage is 2 degrees, and the first set temperature to be cooled to corresponding to the third stage is -2 degrees.

[0073] As another implementation method, the multiple set temperatures are not a fixed value, but change with the change of the temperature of the first space, that is, the temperature of the first space is different, and the multiple set temperatures used to achieve step cooling are different. When achieving step cooling, the speed of the previous cooling is higher than the speed of the next cooling, so as to improve the preservation effect of the food during the step cooling process, that is, the initial cooling speed is fast, and the subsequent cooling speed is slow, so as to improve the refrigeration effect. In other words, the refrigeration control of the storage room can be divided into multiple stages. In the early stage, a larger refrigeration capacity can be used to achieve a faster cooling speed, so that the food can quickly reduce the temperature and prevent the reproduction of microorganisms. As the temperature of the food decreases, the corresponding cooling capacity can also be reduced, that is, the cooling speed can also be reduced, 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 food produces non-freezing liquid inside 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.

[0074] Among them, the first set temperature to be cooled is determined according to the different temperatures of the first space. If the temperature of the newly placed meat is high, the detected temperature of the first space will also be high. For example, if the temperature of the first space is 15 degrees, the first set temperature to be cooled can be determined to be 6 degrees, and the second set temperature is 2 degrees. If the temperature of the newly placed meat is not high, the detected temperature of the first space is not high either, for example, 7 degrees, then the corresponding first set temperature is 0 degrees, and the second set temperature is -2 degrees. That is, the space temperature is higher than the set temperature, and the first temperature difference between the first space temperature and the corresponding first set temperature is greater than the second temperature difference between the second space temperature and the corresponding second set temperature, so that the initial cold amount can be set to a larger cold amount to achieve rapid cooling, and the subsequent cold amount entering is reduced to achieve slow cooling.

[0075] Furthermore, based on the first space temperature and the first set temperature, the temperature difference is determined, and based on the temperature difference and the heat capacity, the first cooling amount required to cool the first food to the first set temperature is determined. As an implementation method, the temperature difference and the heat capacity are multiplied, and the product is the energy required to cool the first food to the first set temperature, that is, the first cooling amount in this application.

[0076] Step 504: Determine a first operating parameter of a damper of the refrigeration device according to the first cooling capacity.

[0077] In an embodiment of the present application, a first operating parameter of the damper of the refrigeration device is determined according to the first cooling capacity. The first operating parameter of the damper includes the opening angle of the damper and / or the air supply speed of the damper, and the air supply speed of the damper refers to the wind speed of the cold air entering through the damper. The cooling capacity is positively correlated with the opening angle, that is, the more cooling capacity is required, the larger the damper opening angle is; the less cooling capacity is required, the smaller the damper opening angle is. The air supply speed is also positively correlated with the cooling capacity, that is, the more cooling capacity is required, the faster the wind speed of the cold air entering through the damper is; the less cooling capacity is required, the smaller the wind speed of the cold air entering through the damper is.

[0078] Step 505, controlling the damper to operate with a first operating parameter to adjust the amount of cold entering the storage chamber.

[0079] In an embodiment of the present application, the damper is controlled to operate with a first operating parameter, so as to determine the required first cooling amount based on the change in the food, and determine the first operating parameter of the damper operation according to the required first cooling amount. Furthermore, the damper is controlled to operate with the first operating parameter to adjust the cooling amount entering the storage chamber, thereby achieving precise refrigeration control, improving the regulation of the food temperature, and increasing the preservation effect of the food.

[0080] Taking the first operating parameter as the opening angle of the damper as an example, the opening angle of the damper can be set to 0 to 90°, then the damper air inlet area can be divided into 90 equal parts, that is, different 90 equal parts of cold capacity, and the damper can be controlled by a proportional-integral-derivative controller (PID) to achieve the hovering of the damper at any angle, wherein the opening angle is different and the amount of cold entering is different. Among them, the correspondence between the damper opening angle and the cold capacity can be determined by pre-testing. As an example, the supply air temperature of the cold air input into the storage room is -26°C, and the speed of the refrigeration fan is constant, then the cold capacity input into the storage space (constant temperature drawer) is positively correlated with the damper air inlet area. Since the opening angle of the damper is from 0 to 90°, the damper air inlet area can be divided into 90 equal parts, that is, different 90 equal parts of cold capacity. By controlling the damper to hover at various opening angles, the cold capacity entering the damper is tested, thereby obtaining the correspondence between the damper opening angle and the input cold capacity. Similarly, the corresponding relationship between the air supply speed of the damper and the cooling capacity can be tested and determined.

[0081] Step 506, monitoring the space temperature of the storage room.

[0082] In the embodiment of the present application, in order to achieve step cooling, after executing the above-mentioned primary refrigeration control, it is necessary to continue to detect the space temperature of the storage room through the NTC sensor to obtain the second space temperature.

[0083] Step 507: in response to the monitored second space temperature being equal to the first set temperature, determining a second set temperature to which the first food is to be cooled.

[0084] The second set temperature is lower than the first set temperature.

[0085] Step 508: Determine a second temperature difference according to the first set temperature and the second set temperature.

[0086] Step 509: Determine a second cooling amount required to cool the first food from the first set temperature to the second set temperature according to the second temperature difference and the heat capacity.

[0087] Step 510, adjusting the amount of cold entering the storage chamber according to the second amount of cold.

[0088] In the embodiment of the present application, for the monitored second space temperature, if the second space temperature is equal to the first set temperature, it means that the first food has not yet been cooled to the target temperature range, then based on the first set temperature to which the temperature is cooled, the redetermination of the cooling amount is triggered, that is, based on the second temperature difference between the second space temperature and the second set temperature, the second cooling amount is determined, and based on the second cooling amount, the cooling amount entering the storage chamber is adjusted to trigger the use of the second cooling rate to continue cooling, wherein the method of adjusting the cooling amount entering the storage chamber according to the second space temperature and the change in the food, that is, steps 507 to 510, can refer to the relevant explanations in the aforementioned embodiments, the principles are the same, and they will not be repeated here.

[0089] Among them, the second temperature difference is greater than the first temperature difference, and the cooling capacity is calculated based on the temperature difference between the detected space temperature and the set temperature and the heat capacity. The larger the temperature difference, the greater the cooling capacity. Therefore, the second cooling capacity is less than the first cooling capacity. The first cooling capacity corresponds to the first cooling rate, and the second cooling capacity corresponds to the second cooling rate. The cooling capacity and the cooling rate are positively correlated, that is, the greater the cooling capacity, the greater the cooling rate, ensuring that the first food is cooled quickly at the beginning of the cooling stage, and then cooled slowly to improve the preservation effect of the food.

[0090] The first cooling rate and the second cooling rate are within any of the following cooling ranges:

[0091] Cool down by 3 to 5 degrees Celsius per hour;

[0092] Cool down by 1 to 3 degrees Celsius per hour;

[0093] Cool down 1 degree Celsius per hour;

[0094] The temperature drops by 0.5 to 1 degree Celsius every 24 hours.

[0095] The second cooling rate is lower than the first cooling rate.

[0096] In the embodiment of the present application, during the process of adjusting the cold amount entering the storage chamber based on the second cold amount, the spatial temperature of the storage chamber is continuously monitored multiple times until the detected spatial temperature is within the target temperature range, thereby dividing the meat cooling period from refrigeration to the end point of ultra-freezing temperature control into multiple sections, and each cooling period corresponds to a set temperature. 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.

[0097] Step 511, in response to the second space temperature being within the set target temperature range, controlling the damper to close to stop regulating the amount of cold entering the storage chamber.

[0098] 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 chamber 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.

[0099] In one implementation of the embodiment of the present application, if it is detected that the temperature of the second space is within the target temperature range, it means that the temperature of the food is already within the target temperature range, and the damper is controlled to close to stop adjusting the refrigeration capacity of the storage chamber in the refrigeration device, that is, stop letting cold air enter the storage chamber through the damper, so that the food is in an ice temperature or super ice temperature state, that is, the food is in a state below the freezing point but not frozen, to achieve a maximized preservation effect, so that users can obtain better preservation quality.

[0100] In the refrigeration control method of the embodiment of the present application, step-by-step cooling is performed based on the change in food detected by the sensor and the measured spatial temperature of the storage room to achieve precise refrigeration control, ensuring that the first food is cooled quickly at the initial 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 non-freezing liquid inside to combat the low temperature. To combat the low temperature, the internal moisture structure and enzyme activity are reduced, so that the wet food is kept in an ultra-ice temperature state without freezing, achieving the best preservation effect.

[0101] In order to implement the above embodiment, the embodiment of the present application also proposes a refrigeration control device.

[0105] The control module 62 is used to control the refrigeration device to perform refrigeration according to the change in the amount of food in the storage chamber.

[0106] Furthermore, in an implementation of the embodiment of the present application, the determination module 61 is also used to detect through a weight sensor in the storage room to obtain the weight change of the food in the storage room.

[0107] In one implementation of the embodiment of the present application, the determination module 61 is further configured to obtain the volume change of the food in the storage chamber by detecting through a distance measuring sensor in the storage chamber.

[0108] In one implementation of the embodiment of the present application, the control module 62 is further configured to:

[0109] Obtaining a first spatial temperature of the storage chamber detected after the first food is placed in the storage chamber;

[0110] The amount of cold air entering the storage chamber is adjusted according to the change in the food material and the temperature of the first space.

[0111] In one implementation of the embodiment of the present application, the control module 62 is further configured to:

[0112] Determining a first cooling amount required for the first food according to the change in the food and the temperature of the first space;

[0113] Determining a first operating parameter of a damper of the refrigeration device according to the first cooling capacity;

[0114] The damper is controlled to operate at the first operating parameter to adjust the amount of cold entering the storage chamber.

[0115] In one implementation of the embodiment of the present application, the control module 62 is further configured to:

[0116] Determining the heat capacity corresponding to the first food material according to the change amount of the food material;

[0117] Determining a first set temperature to which the first food is to be cooled according to the first space temperature;
