[0002] As society continues to develop, people have increasingly higher demands for the freshness of food. Meat, as an essential source of fat and protein in daily life, is currently mainly stored through refrigeration and freezing. Refrigeration temperatures are generally between 0 and 5°C, keeping meat above freezing point so it doesn't freeze, but the shelf life is only about 3 days. Freezing temperatures are generally between -18 and -38°C. Freezing can extend the shelf life of meat, but it is difficult to thaw, and the ice crystals are relatively large. When thawing, these ice crystals can puncture cells, causing a significant loss of nutrients. Summary of the Invention

[0003] This application provides a method, device, storage medium, and electronic device for controlling a refrigerator drawer, in order to solve the technical problem that food loses a large amount of nutrients when it is frozen in a refrigerator.

[0006] As an optional example, the aforementioned adjustment module includes: a first control unit, configured to control the nine-grid cooling assembly to operate at a first number of open damper groups to maintain the indoor temperature of the refrigerator drawer within a first temperature range; a second control unit, configured to, after the nine-grid cooling assembly has operated at the first number of open damper groups for a first duration, control the nine-grid cooling assembly to operate at a second number of open damper groups to maintain the indoor temperature within a second temperature range, wherein the second number is greater than the first number, and the highest temperature in the second temperature range is lower than the lowest temperature in the first temperature range; and a third control unit. The first control unit is configured to, after the nine-grid cooling component has operated for a second period of time with the number of damper groups opened being the second number, control the nine-grid cooling component to operate with the number of damper groups opened being the third number, so as to maintain the indoor temperature in a third temperature range, wherein the third number is greater than the second number, and the highest temperature in the third temperature range is less than the lowest temperature in the second temperature range; the second control unit is configured to, after the nine-grid cooling component has operated for a third period of time with the number of damper groups opened being the third number, control the nine-grid cooling component to operate with the number of damper groups opened being the second number, so as to maintain the indoor temperature in the second temperature range.

[0007] As an optional example, the first control unit includes: a first control subunit for controlling the opening of the first number of dampers in the damper group; a second control subunit for controlling the number of dampers opened to decrease by one when the indoor temperature is detected to be lower than the lowest temperature of the first temperature range, so as to keep the indoor temperature in the first temperature range; and a third control subunit for controlling the number of dampers opened to increase by one when the indoor temperature is detected to be higher than the highest temperature of the first temperature range, so as to keep the indoor temperature in the first temperature range.

[0008] As an optional example, the first control unit includes: a fourth control subunit for controlling the opening of the second number of dampers in the damper group; a fifth control subunit for controlling the number of dampers opened to decrease by one when the indoor temperature is detected to be lower than the lowest temperature of the second temperature range, so as to keep the indoor temperature in the second temperature range; and a sixth control subunit for controlling the number of dampers opened to increase by one when the indoor temperature is detected to be higher than the highest temperature of the second temperature range, so as to keep the indoor temperature in the second temperature range.

[0009] As an optional example, the third control unit includes: a seventh control subunit for controlling the opening of the third number of dampers in the damper group; and an eighth control subunit for controlling the number of dampers in the damper group to decrease by one when the indoor temperature is detected to be lower than the lowest temperature in the third temperature range, so as to keep the indoor temperature in the third temperature range.

[0010] Thirdly, this application provides a refrigerator drawer, comprising: a nine-compartment cooling assembly, including a cooling plate and a damper assembly, wherein the damper assembly and the cooling plate form an air duct, and the nine-compartment cooling assembly is used to transmit cold air through the damper assembly to the air duct to cool the cooling plate, thereby regulating the indoor temperature of the refrigerator drawer; a temperature sensor for detecting the indoor temperature; and a control module for adjusting the number of openings of the damper assembly according to the indoor temperature when a target object is detected in the refrigerator drawer, thereby regulating the indoor temperature.

[0011] As an optional example, the control module is also used to control the opening of the first number of dampers in the damper group. When the indoor temperature is detected to be lower than the lowest temperature of the first temperature range, the number of dampers opened in the damper group is reduced by one to keep the indoor temperature in the first temperature range. When the indoor temperature is detected to be higher than the highest temperature of the first temperature range, the number of dampers opened in the damper group is increased by one to keep the indoor temperature in the first temperature range.

[0012] As an optional example, the control module is further configured to control the second number of dampers in the damper group to open after the nine-grid cooling assembly has been running for a first period of time with the number of damper groups open as the first number; if the indoor temperature is detected to be lower than the lowest temperature of the second temperature range, control the number of damper groups to open to decrease by one so that the indoor temperature is maintained in the second temperature range; if the indoor temperature is detected to be higher than the highest temperature of the second temperature range, control the number of damper groups to open to increase by one so that the indoor temperature is maintained in the second temperature range.

[0013] As an optional example, the control module is also used to control the third number of dampers in the damper group to open after the nine-grid cooling assembly has been running for a second period of time with the number of damper groups open as the second number. If the indoor temperature is detected to be lower than the lowest temperature in the third temperature range, the control module controls the number of damper groups to open to decrease by one so that the indoor temperature is maintained in the third temperature range.

[0014] Fourthly, this application provides a storage medium storing a computer program, wherein the computer program is executed by a processor to perform the above-described refrigerator drawer control method.

[0016] In this embodiment, when a target object is detected in a refrigerator drawer, the indoor temperature of the drawer is obtained. Based on the indoor temperature, the number of openings of the damper assembly of the nine-compartment cooling system in the drawer is adjusted to regulate the indoor temperature. The nine-compartment cooling system is used to transmit cold air through the damper assembly to the air duct formed between the damper assembly and the cooling plate of the nine-compartment cooling system, thereby cooling the cooling plate and regulating the indoor temperature. Since the above method uses a combination of air cooling and direct cooling to cool the refrigerator drawer, and the nine-compartment cooling system consists of a damper assembly and a cooling plate, when cooling the refrigerator drawer, cold air is transmitted through the damper assembly to the air duct formed between the damper assembly and the cooling plate to cool the cooling plate, thereby cooling the refrigerator drawer. This avoids the loss of moisture and nutrients caused by cold air blowing directly on food, achieving the goal of better maintaining the quality and nutritional value of food, and thus solving the technical problem of a large loss of food nutrients when freezing food in a refrigerator.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0029] According to a first aspect of the embodiments of this application, a method for controlling a refrigerator drawer is provided, optionally, as follows: Figure 1 As shown, the above method includes:

[0030] S102, if a target object is detected in the refrigerator drawer, the indoor temperature of the refrigerator drawer is obtained;

[0031] S104, adjust the number of openings of the air damper group of the nine-grid cooling component of the refrigerator drawer according to the indoor temperature, so as to regulate the indoor temperature. The nine-grid cooling component is used to transmit cold air through the air damper group to the air duct formed between the air damper group and the cooling plate of the nine-grid cooling component, so as to cool the cooling plate and regulate the indoor temperature.

[0032] Optionally, meat products are mainly stored using refrigeration and freezing. Refrigeration temperatures are generally between 0 and 5°C, keeping meat above freezing point. While meat doesn't freeze, its shelf life is only about 3 days. Freezing temperatures are generally between -18 and -38°C. Freezing extends the shelf life of meat, but it's difficult to thaw, and the large ice crystals can puncture cells during thawing, causing significant nutrient loss. Therefore, in this embodiment, a combination of air cooling and direct cooling is used to cool the refrigerator drawer. A nine-compartment cooling system is added to the drawer. This system consists of a damper assembly and a cooling tray. The working principle of the nine-compartment cooling system is that when cooling the drawer, cold air is transmitted through the damper assembly to the air duct formed between the damper assembly and the cooling tray, cooling the cooling tray and thus the drawer. Therefore, the number of dampers opened can be adjusted according to the required temperature of the stored food to regulate the drawer's internal temperature. Taking meat as an example, when the system detects that a user has stored meat in a refrigerator drawer, it adjusts the number of opening doors to keep the drawer temperature within the range required for the meat. This prevents cold air from blowing directly on the food and causing moisture and nutrient loss, thus better preserving the quality and nutritional value of the food. This solves the technical problem of significant nutrient loss when freezing food in a refrigerator.

[0033] As an alternative example, adjusting the number of opening sections of the nine-compartment cooling unit in the refrigerator drawer to regulate the indoor temperature includes:

[0034] The nine-grid cooling unit is controlled to operate with the number of air dampers opened as the first quantity, so as to keep the interior temperature of the refrigerator drawer in the first temperature range.

[0035] After the nine-grid cooling unit operates for a first duration with the number of damper groups open as the first number, the nine-grid cooling unit is controlled to operate with the number of damper groups open as the second number, so that the indoor temperature is maintained in the second temperature range, wherein the second number is greater than the first number, and the highest temperature in the second temperature range is less than the lowest temperature in the first temperature range.

[0036] After the nine-grid cooling unit operates for a second duration with the number of damper groups open as the second number, the nine-grid cooling unit is controlled to operate with the number of damper groups open as the third number, so that the indoor temperature is maintained in the third temperature range. The third number is greater than the second number, and the highest temperature in the third temperature range is less than the lowest temperature in the second temperature range.

[0037] After the nine-grid cooling unit operates for a third duration with the third number of damper openings, the nine-grid cooling unit is controlled to operate with the second number of damper openings to maintain the indoor temperature in the second temperature range.

[0038] Optionally, meat products are primarily stored using refrigeration and freezing. Refrigeration temperatures are generally 0–5°C, keeping meat above freezing point without freezing, but the shelf life is only about 3 days. Freezing temperatures are generally -18–-38°C, extending the shelf life of meat, but it is difficult to thaw, and the large ice crystals can puncture cells during thawing, causing significant nutrient loss. Therefore, in this embodiment, the nine-grid cooling system is first controlled to operate with the number of open dampers as the primary setting, maintaining the refrigerator drawer temperature at 2–3°C for three hours to achieve a uniform temperature for the meat, resulting in better and more even cooling. Then, the nine-grid cooling system is controlled to operate with the number of open dampers as the secondary setting, maintaining the refrigerator drawer temperature at -3–-5°C for two hours for supercooling, allowing an ice film to form on the surface of the meat to prevent damage from sudden low temperatures. Finally, the nine-grid cooling system is controlled to operate with the number of open dampers as the tertiary setting, maintaining the refrigerator drawer temperature at -37–-39°C. This process is maintained for three hours to rapidly freeze meat, ensuring it is completely frozen inside and out. Finally, the nine-grid cooling system operates at the second-highest opening setting of the damper assembly to maintain an internal temperature of -3 to -5°C for micro-freezing and preservation. This prevents the meat from being difficult to thaw, thus avoiding significant nutrient loss. This achieves better preservation of food quality and nutritional value, thereby solving the technical problem of substantial nutrient loss during food freezing.

[0039] As an alternative example, controlling the nine-compartment cooling system to operate with the number of damper groups open as a first number to maintain the interior temperature of the refrigerator drawer within a first temperature range includes:

[0040] The first number of dampers in the control damper group are opened;

[0041] If the indoor temperature is detected to be lower than the lowest temperature in the first temperature range, the number of opening dampers in the control group is reduced by one to keep the indoor temperature in the first temperature range.

[0042] If the indoor temperature is detected to be higher than the highest temperature in the first temperature range, the number of opening dampers is increased by one to keep the indoor temperature in the first temperature range.

[0043] Optionally, in this embodiment, the damper assembly can have nine dampers. When the indoor temperature of the refrigerator drawer needs to be maintained between 2 and 3°C, any three dampers of the nine-grid cooling system are opened (i.e., the first, second, and third dampers), while the remaining six dampers remain closed to lower the indoor temperature to between 2 and 3°C. A temperature sensor periodically checks the indoor temperature of the refrigerator drawer. When the detected indoor temperature is below 2°C, it is considered too low, and any one of the open dampers is closed to raise the indoor temperature to between 2 and 3°C. When the detected indoor temperature is between 2 and 3°C, the status quo is maintained. When the detected indoor temperature is above 3°C, it is considered too high, and any one of the closed dampers is opened to lower the indoor temperature to between 2 and 3°C. This process, involving the control of the nine dampers, maintains the indoor temperature of the refrigerator drawer between 2 and 3°C for three hours.

[0044] As an optional example, after the nine-grid cooling unit operates for a first duration with the number of damper assemblies open as a first number, controlling the nine-grid cooling unit to operate with the number of damper assemblies open as a second number, so as to maintain the indoor temperature in a second temperature range, includes:

[0045] The second number of dampers in the control damper group are opened;

[0046] If the indoor temperature is detected to be lower than the lowest temperature in the second temperature range, the number of opening dampers in the control group is reduced by one to keep the indoor temperature in the second temperature range.

[0047] If the indoor temperature is detected to be higher than the highest temperature in the second temperature range, the number of opening dampers in the control group is increased by one to keep the indoor temperature in the second temperature range.

[0048] Optionally, in this embodiment, the damper assembly can have nine dampers. When the indoor temperature of the refrigerator drawer needs to be maintained between -3 and -5°C, any six dampers of the nine-grid cooling system are opened (i.e., the first, second, third, fourth, fifth, and sixth dampers), while the remaining three dampers remain closed to lower the indoor temperature to between -3 and -5°C. A temperature sensor periodically checks the indoor temperature of the refrigerator drawer. When the detected indoor temperature is below -5°C, it is considered too low, and any one of the open dampers is closed to raise the indoor temperature to between -3 and -5°C. If the detected indoor temperature is between -3 and -5°C, the status quo is maintained. If the detected indoor temperature is above -3°C, it is considered too high, and any one of the closed dampers is opened to lower the indoor temperature to between -3 and -5°C. This process, controlling the opening and closing of the nine dampers, maintains the indoor temperature of the refrigerator drawer between -3 and -5°C for two hours.

[0049] As an optional example, after the nine-grid cooling unit has been running for a second duration with the number of damper groups open as a second number, controlling the nine-grid cooling unit to run with the number of damper groups open as a third number, so as to maintain the indoor temperature in a third temperature range, includes:

[0050] The third number of dampers in the control damper group is opened;

[0051] If the indoor temperature is detected to be lower than the lowest temperature in the third temperature range, the number of opening dampers in the control group is reduced by one to keep the indoor temperature in the third temperature range.

[0052] Optionally, in this embodiment, the damper assembly can have nine dampers. When the indoor temperature of the refrigerator drawer needs to be maintained between -37 and -39°C, all dampers of the nine-grid cooling assembly are opened to lower the indoor temperature to between -37 and -39°C. A temperature sensor periodically checks the indoor temperature of the refrigerator drawer. When the detected indoor temperature is below -39°C, it is considered too low, and any one of the open dampers is closed, raising the indoor temperature of the refrigerator drawer to between -37 and -39°C. If the detected indoor temperature is between -37 and -39°C, the current state is maintained. If the detected indoor temperature is above -37°C, it is considered too high, and all nine dampers remain open until the indoor temperature of the refrigerator drawer drops to between -37 and -39°C. This process requires controlling the opening and closing of the nine dampers to maintain the indoor temperature of the refrigerator drawer between -37 and -39°C for three hours.

[0053] To illustrate with an example, this application designs a method for controlling a refrigerator drawer, employing a combination of air cooling and direct cooling to cool the drawer. Figure 2 The overall structure diagram of the refrigerator shown is as follows: Figure 3 The diagram shows the structure of the nine-compartment refrigeration unit. 1 is the refrigerator drawer, 2 is the nine-compartment structure, 3 is the temperature sensor, 4 is the air inlet at the top of the drawer, 5 is the plastic outer shell, 6 is the cooling tray, and 7, 8, 9, 10, 11, 12, 13, 14, and 15 are the air damper switches for compartments 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively. 16 is the air duct. The main structure of the refrigerator drawer is a nine-compartment refrigeration unit with a plastic inlay and metal cooling tray at the top. Each metal cooling tray compartment has a corresponding air duct and air damper. The temperature sensor detects the temperature of the drawer compartments and can control the opening and closing of different numbers of the nine-compartment air dampers based on the different temperature requirements of the food and the detected temperature of the drawer compartments. This ensures the preservation of food and prevents direct airflow from causing moisture and nutrient loss. The specific control steps are as follows:

[0054] First step, such as Figure 4 The diagram showing the temperature changes inside the drawer illustrates that food needs to be stored at a temperature between 2 and 3°C (t1) for 3 hours to reach a uniform temperature. During this time, three of the nine drawer compartments require cooling: dampers 7, 8, and 9 automatically open, while the remaining six compartments remain closed. A temperature sensor inside the drawer periodically checks the current temperature (T1). If T1 is between 2 and 3°C, the current temperature is maintained. If T1 > 3°C, one more damper compartment automatically opens. If T1 < 2°C, one damper compartment automatically closes.

[0055] The second step, as Figure 4 The diagram showing the temperature change inside the drawer indicates that the food has reached a uniform temperature and needs to be cooled further. It needs to be stored between -3 and -5°C for 2 hours. At this time, six of the nine drawer's dampers automatically open for cooling: dampers 7, 8, 9, 10, 11, and 12. The remaining three dampers remain closed. The temperature sensor inside the drawer periodically checks the current temperature T2. If T2 is between -3 and -5°C, the current temperature is maintained. If T2 is greater than -3°C, one more damper automatically opens. If T2 is less than -5°C, one damper automatically closes.

[0056] The third step, as Figure 4The diagram showing the temperature changes inside the drawer indicates that the food has already been supercooled and needs to be rapidly cooled and frozen. It needs to be stored at t3 (-37 to -39°C) for 3 hours. At this point, all nine drawer compartments are open for cooling: dampers 7, 8, 9, 10, 11, 12, 13, 14, and 15. The temperature sensor inside the drawer periodically checks the current temperature T3. If T3 is between -37 and -39°C, the current state is maintained. If T3 > -37°C, all dampers remain open until the temperature reaches between -37 and -39°C. If T3 < -39°C, one damper is automatically closed.

[0057] Step four, as Figure 4 The diagram showing the temperature changes inside the drawer indicates that the food has completed rapid freezing and needs to be stored at -3 to -5℃ for micro-freezing. Three of the nine-compartment air dampers are automatically closed; only six dampers (7, 8, 9, 10, 11, and 12) need to be opened. The air dampers can be opened and closed at any time based on the ambient temperature detected by the temperature sensor to achieve optimal storage conditions.

[0058] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to this application.

[0059] According to a second aspect of the embodiments of this application, a control device for a refrigerator drawer is provided, optionally, such as Figure 5 As shown, it includes:

[0060] The acquisition module 502 is used to acquire the indoor temperature of the refrigerator drawer when a target object is detected in the refrigerator drawer.

[0061] The adjustment module 504 is used to adjust the number of openings of the damper group of the nine-grid refrigeration component of the refrigerator drawer according to the indoor temperature, so as to regulate the indoor temperature. The nine-grid refrigeration component is used to transmit cold air through the damper group to the air duct formed between the damper group and the cooling plate of the nine-grid refrigeration component, so as to cool the cooling plate and regulate the indoor temperature.

[0062] Optionally, meat products are mainly stored using refrigeration and freezing. Refrigeration temperatures are generally between 0 and 5°C, keeping meat above freezing point. While meat doesn't freeze, its shelf life is only about 3 days. Freezing temperatures are generally between -18 and -38°C. Freezing extends the shelf life of meat, but it's difficult to thaw, and the large ice crystals can puncture cells during thawing, causing significant nutrient loss. Therefore, in this embodiment, a combination of air cooling and direct cooling is used to cool the refrigerator drawer. A nine-compartment cooling system is added to the drawer. This system consists of a damper assembly and a cooling tray. The working principle of the nine-compartment cooling system is that when cooling the drawer, cold air is transmitted through the damper assembly to the air duct formed between the damper assembly and the cooling tray, cooling the cooling tray and thus the drawer. Therefore, the number of dampers opened can be adjusted according to the required temperature of the stored food to regulate the drawer's internal temperature. Taking meat as an example, when the system detects that a user has stored meat in a refrigerator drawer, it adjusts the number of opening doors to keep the drawer temperature within the range required for the meat. This prevents cold air from blowing directly on the food and causing moisture and nutrient loss, thus better preserving the quality and nutritional value of the food. This solves the technical problem of significant nutrient loss when freezing food in a refrigerator.

[0063] As an optional example, the adjustment module includes:

[0064] The first control unit is used to control the nine-grid refrigeration assembly to operate with the number of air damper groups opened as the first number, so as to keep the indoor temperature of the refrigerator drawer in a first temperature range.

[0065] The second control unit is used to control the nine-grid cooling component to operate with the number of damper groups open as the first number for a first time after the nine-grid cooling component has been operating with the number of damper groups open as the second number, so as to keep the indoor temperature in a second temperature range, wherein the second number is greater than the first number, and the highest temperature in the second temperature range is less than the lowest temperature in the first temperature range.

[0066] The third control unit is used to control the nine-grid cooling component to operate with the number of damper groups open to a third number after the nine-grid cooling component has been operating for a second time with the number of damper groups open to a second number, so as to keep the indoor temperature in a third temperature range, wherein the third number is greater than the second number, and the highest temperature in the third temperature range is less than the lowest temperature in the second temperature range.

[0067] The fourth control unit is used to control the nine-grid cooling unit to operate at the second number of open damper groups after the nine-grid cooling unit has been running for a third time with the third number of open damper groups, so as to keep the indoor temperature in the second temperature range.

[0068] Optionally, meat products are primarily stored using refrigeration and freezing. Refrigeration temperatures are generally 0–5°C, keeping meat above freezing point without freezing, but the shelf life is only about 3 days. Freezing temperatures are generally -18–-38°C, extending the shelf life of meat, but it is difficult to thaw, and the large ice crystals can puncture cells during thawing, causing significant nutrient loss. Therefore, in this embodiment, the nine-grid cooling system is first controlled to operate with the number of open dampers as the primary setting, maintaining the refrigerator drawer temperature at 2–3°C for three hours to achieve a uniform temperature for the meat, resulting in better and more even cooling. Then, the nine-grid cooling system is controlled to operate with the number of open dampers as the secondary setting, maintaining the refrigerator drawer temperature at -3–-5°C for two hours for supercooling, allowing an ice film to form on the surface of the meat to prevent damage from sudden low temperatures. Finally, the nine-grid cooling system is controlled to operate with the number of open dampers as the tertiary setting, maintaining the refrigerator drawer temperature at -37–-39°C. This process is maintained for three hours to rapidly freeze meat, ensuring it is completely frozen inside and out. Finally, the nine-grid cooling system operates at the second-highest opening setting of the damper assembly to maintain an internal temperature of -3 to -5°C for micro-freezing and preservation. This prevents the meat from being difficult to thaw, thus avoiding significant nutrient loss. This achieves better preservation of food quality and nutritional value, thereby solving the technical problem of substantial nutrient loss during food freezing.

[0069] As an optional example, the first control unit includes:

[0070] The first control subunit is used to control the opening of a first number of dampers in the damper group;

[0071] The second control subunit is used to control the number of opening dampers to decrease by one when the indoor temperature is detected to be lower than the lowest temperature in the first temperature range, so as to keep the indoor temperature in the first temperature range.

[0072] The third control subunit is used to increase the number of open damper groups by one when the indoor temperature is detected to be higher than the highest temperature in the first temperature range, so as to keep the indoor temperature in the first temperature range.

[0073] Optionally, in this embodiment, the damper assembly can have nine dampers. When the indoor temperature of the refrigerator drawer needs to be maintained between 2 and 3°C, any three dampers of the nine-grid cooling system are opened (i.e., the first, second, and third dampers), while the remaining six dampers remain closed to lower the indoor temperature to between 2 and 3°C. A temperature sensor periodically checks the indoor temperature of the refrigerator drawer. When the detected indoor temperature is below 2°C, it is considered too low, and any one of the open dampers is closed to raise the indoor temperature to between 2 and 3°C. When the detected indoor temperature is between 2 and 3°C, the status quo is maintained. When the detected indoor temperature is above 3°C, it is considered too high, and any one of the closed dampers is opened to lower the indoor temperature to between 2 and 3°C. This process, involving the control of the nine dampers, maintains the indoor temperature of the refrigerator drawer between 2 and 3°C for three hours.

[0074] As an optional example, the first control unit includes:

[0075] The fourth control subunit is used to control the opening of the second number of dampers in the damper group;

[0076] The fifth control subunit is used to control the number of opening dampers to decrease by one when the indoor temperature is detected to be lower than the lowest temperature in the second temperature range, so as to keep the indoor temperature in the second temperature range.

[0077] The sixth control subunit is used to increase the number of opening dampers by one when the indoor temperature is detected to be higher than the highest temperature in the second temperature range, so as to keep the indoor temperature in the second temperature range.

[0078] Optionally, in this embodiment, the damper assembly can have nine dampers. When the indoor temperature of the refrigerator drawer needs to be maintained between -3 and -5°C, any six dampers of the nine-grid cooling system are opened (i.e., the first, second, third, fourth, fifth, and sixth dampers), while the remaining three dampers remain closed to lower the indoor temperature to between -3 and -5°C. A temperature sensor periodically checks the indoor temperature of the refrigerator drawer. When the detected indoor temperature is below -5°C, it is considered too low, and any one of the open dampers is closed to raise the indoor temperature to between -3 and -5°C. If the detected indoor temperature is between -3 and -5°C, the status quo is maintained. If the detected indoor temperature is above -3°C, it is considered too high, and any one of the closed dampers is opened to lower the indoor temperature to between -3 and -5°C. This process, controlling the opening and closing of the nine dampers, maintains the indoor temperature of the refrigerator drawer between -3 and -5°C for two hours.

[0079] As an optional example, the third control unit includes:

[0080] The seventh control subunit is used to control the opening of the third number of dampers in the damper group;

[0081] The eighth control subunit is used to reduce the number of opening dampers by one when the indoor temperature is detected to be lower than the lowest temperature in the third temperature range, so as to keep the indoor temperature in the third temperature range.

[0082] Optionally, in this embodiment, the damper assembly can have nine dampers. When the indoor temperature of the refrigerator drawer needs to be maintained between -37 and -39°C, all dampers of the nine-grid cooling assembly are opened to lower the indoor temperature to between -37 and -39°C. A temperature sensor periodically checks the indoor temperature of the refrigerator drawer. When the detected indoor temperature is below -39°C, it is considered too low, and any one of the open dampers is closed, raising the indoor temperature of the refrigerator drawer to between -37 and -39°C. If the detected indoor temperature is between -37 and -39°C, the current state is maintained. If the detected indoor temperature is above -37°C, it is considered too high, and all nine dampers remain open until the indoor temperature of the refrigerator drawer drops to between -37 and -39°C. This process requires controlling the opening and closing of the nine dampers to maintain the indoor temperature of the refrigerator drawer between -37 and -39°C for three hours.

[0083] For other examples of this embodiment, please refer to the examples above, which will not be repeated here.

[0084] According to a third aspect of the embodiments of this application, a refrigerator drawer is provided, optionally, as... Figure 6 As shown, it includes:

[0085] The nine-grid cooling component 602 includes a cooling plate and an air damper assembly. An air duct is formed between the air damper assembly and the cooling plate. The nine-grid cooling component is used to transmit cold air through the air damper assembly to the air duct to cool the cooling plate and regulate the interior temperature of the refrigerator drawer.

[0086] Temperature sensor 604 is used to detect indoor temperature;

[0087] The control module 606 is used to adjust the number of openings of the damper assembly according to the indoor temperature when a target object is detected in the refrigerator drawer.

[0088] Optionally, meat products are mainly stored using refrigeration and freezing. Refrigeration temperatures are generally 0–5°C, keeping meat above freezing point so it doesn't freeze, but the shelf life is only about 3 days. Freezing temperatures are generally -18 to -38°C, extending the shelf life of meat, but it's difficult to thaw, and the ice crystals are large, puncturing cells during thawing and causing significant nutrient loss. Therefore, in this embodiment, a combination of air cooling and direct cooling is used to cool the refrigerator drawers. Figure 2 The overall structure diagram of the refrigerator shown is as follows: Figure 3 The diagram shows the structure of the nine-compartment cooling system. 1 is the refrigerator drawer, 2 is the nine-compartment structure, 3 is the temperature sensor, 4 is the air inlet at the top of the drawer, 5 is the plastic outer shell, 6 is the cooling tray, and 7, 8, 9, 10, 11, 12, 13, 14, and 15 are the air damper switches for compartments 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively. 16 is the air duct. The main structure of the refrigerator drawer is a nine-compartment cooling system with a plastic-embedded metal cooling tray at the top. Each metal cooling tray compartment has a corresponding air duct and air damper. The temperature sensor detects the temperature within the drawer compartments and can control the opening and closing of different numbers of the nine-compartment air dampers based on the different temperature requirements of the food and the detected temperature of the drawer compartments. This ensures proper food storage and preservation, preventing direct airflow from causing moisture and nutrient loss. The working principle of the nine-compartment cooling system is as follows: when cooling the refrigerator drawer, cold air is transmitted through the damper assembly to the air duct formed between the damper assembly and the cooling tray, cooling the cooling tray and thus the refrigerator drawer. Therefore, the control module can adjust the number of damper assemblies opened according to the required temperature of the stored food, thereby regulating the interior temperature of the refrigerator drawer. Specifically, the control module first controls the nine-compartment cooling system to operate at the first number of damper assemblies opened, maintaining the interior temperature of the refrigerator drawer at 2-3℃ for three hours, allowing meat to reach a uniform temperature for better and more even cooling. Then, the control module controls the nine-compartment cooling system to operate at the second number of damper assemblies opened, maintaining the interior temperature of the refrigerator drawer at -3 to -5℃ for two hours, performing supercooling to form an ice film on the surface of the meat, preventing damage from sudden low temperatures. Finally, the control module controls the nine-compartment cooling system to operate at the third number of damper assemblies opened, maintaining the interior temperature of the refrigerator drawer at -37 to -39℃. This process is maintained for three hours to rapidly freeze meat, ensuring it is completely frozen inside and out. Finally, the nine-grid cooling system operates at the second-highest opening setting of the damper assembly to maintain an internal temperature of -3 to -5°C for micro-freezing and preservation. This prevents the meat from being difficult to thaw, thus avoiding significant nutrient loss. This achieves better preservation of food quality and nutritional value, thereby solving the technical problem of substantial nutrient loss during food freezing.

[0089] As an optional example, the control module is also used to control the opening of a first number of dampers in the damper group. When the indoor temperature is detected to be lower than the lowest temperature of the first temperature range, the number of dampers opened in the damper group is reduced by one to keep the indoor temperature in the first temperature range. When the indoor temperature is detected to be higher than the highest temperature of the first temperature range, the number of dampers opened in the damper group is increased by one to keep the indoor temperature in the first temperature range.

[0090] Optionally, in this embodiment, when the indoor temperature of the refrigerator drawer needs to be maintained between 2 and 3°C, the control module controls any three dampers of the nine-compartment cooling system to open (i.e., the first, second, and third dampers), while the remaining six dampers remain closed, to lower the indoor temperature to between 2 and 3°C. The temperature sensor periodically checks the indoor temperature of the refrigerator drawer. When the detected indoor temperature is below 2°C, it is considered too low, and the control module closes any one of the open dampers, raising the indoor temperature of the refrigerator drawer to between 2 and 3°C. When the detected indoor temperature is between 2 and 3°C, the status quo is maintained. When the detected indoor temperature is above 3°C, it is considered too high, and the control module opens any one of the closed dampers, lowering the indoor temperature of the refrigerator drawer to between 2 and 3°C. During this stage, the control module maintains the indoor temperature of the refrigerator drawer between 2 and 3°C for three hours by controlling the opening and closing of the nine dampers.

[0091] As an optional example, the control module is also used to control a second number of dampers in the damper group to open after the nine-grid cooling assembly has been running for a first period of time with the number of damper groups open as the first number. If the indoor temperature is detected to be lower than the lowest temperature of the second temperature range, the control module controls the number of damper groups to open to decrease by one so that the indoor temperature is maintained in the second temperature range. If the indoor temperature is detected to be higher than the highest temperature of the second temperature range, the control module controls the number of damper groups to open to increase by one so that the indoor temperature is maintained in the second temperature range.

[0092] Optionally, in this embodiment, when the indoor temperature of the refrigerator drawer needs to be maintained between -3 and -5°C, the control module controls any six of the nine-grid cooling components to open (i.e., the first, second, third, fourth, fifth, and sixth air vents), while the remaining three air vents remain closed, thus lowering the indoor temperature to between -3 and -5°C. The temperature sensor periodically checks the indoor temperature of the refrigerator drawer. When the detected indoor temperature is below -5°C, it is considered too low, and the control module closes any one of the open air vents, raising the indoor temperature of the refrigerator drawer to between -3 and -5°C. When the detected indoor temperature is between -3 and -5°C, the status quo is maintained. When the detected indoor temperature is above -3°C, it is considered too high, and the control module opens any one of the closed air vents, lowering the indoor temperature of the refrigerator drawer to between -3 and -5°C. During this stage, the control module controls the opening and closing of the nine air vents to maintain the indoor temperature of the refrigerator drawer between -3 and -5°C for two hours.

[0093] As an optional example, the control module is also used to control a third number of dampers in the damper group to open after the nine-grid cooling assembly has been running for a second period of time with the number of damper groups open as the second number. If the indoor temperature is detected to be lower than the lowest temperature of the third temperature range, the control module controls the number of damper groups to open to decrease by one so that the indoor temperature is maintained in the third temperature range.

[0094] Optionally, in this embodiment, the damper assembly can have nine dampers. When the indoor temperature of the refrigerator drawer needs to be maintained between -37 and -39°C, the control module controls all the dampers of the nine-grid cooling assembly to open, thereby lowering the indoor temperature to between -37 and -39°C. The temperature sensor periodically checks the indoor temperature of the refrigerator drawer. When the detected indoor temperature is below -39°C, it is considered too low. At this time, the control module closes any one of the open dampers, raising the indoor temperature of the refrigerator drawer to between -37 and -39°C. When the detected indoor temperature is between -37 and -39°C, the status quo is maintained. When the detected indoor temperature is above -37°C, it is considered too high. At this time, the control module continues to keep all nine dampers open until the indoor temperature of the refrigerator drawer drops to between -37 and -39°C. During this stage, the control module controls the opening and closing of the nine dampers to maintain the indoor temperature of the refrigerator drawer between -37 and -39°C for three hours.
