[0061] In some embodiments, the flexible adjustment portion 41 includes: a enclosure in the shape of an accordion pleat, extending upward from the upper part of the main body 40.

[0062] The enclosure is in an accordion pleat shape, so that the enclosure has a certain flexibility and can be stretched and compressed.

[0064] Combination Figure 5 As shown, the embodiment of the present disclosure provides a method for controlling a refrigerator, comprising:

[0065] S10, the control device obtains the actual distance between the storage rack and the bottom of the drawer.

[0066] Here, the actual distance between the shelf and the bottom of the drawer can reflect the capacity of the drawer. The capacity of the drawer can be calculated by multiplying the actual distance by the bottom area of ​​the drawer. The actual distance is proportional to the capacity. The larger the actual distance, the larger the capacity of the drawer, and the smaller the actual distance, the smaller the capacity of the drawer. The cooling capacity provided to the drawer can be determined based on the capacity of the drawer. When the capacity of the drawer is large, more cooling capacity is required, and when the capacity of the drawer is small, less cooling capacity is required.

[0067] Optionally, a distance sensor is provided at the bottom of the rack to detect the actual distance between the rack and the bottom of the drawer. The control device receives the distance data detected by the distance sensor capable of wireless communication therewith and takes it as the actual distance.

[0068] S20, the control device controls the air inlet damper to open at a first initial angle according to the correspondence between the actual distance and the opening angle of the air inlet damper.

[0069] Here, the actual distance is positively correlated with the opening angle of the air inlet damper. The larger the actual distance is, the larger the capacity of the drawer is and the greater the required cooling capacity is. Therefore, the opening angle of the air inlet damper is controlled to be larger, so that more cooling capacity can be input into the drawer.

[0070] Optionally, the range of the opening angle α of the air inlet damper is: 0°<α≤90°, and the range of the actual distance L is: 15cm≤L≤30cm. Within this range, the correspondence between the actual distance and the opening angle of the air inlet damper can be set.

[0071] The correspondence between the actual distance and the opening angle of the air inlet door can be in the form of a one-to-one correspondence data table. In this case, the correspondence between the actual distance and the opening angle of the air inlet door can be stored in a database in advance. After obtaining the actual distance between the shelf and the bottom of the drawer, the corresponding opening angle of the air inlet door can be obtained by querying the database, and the opening angle is used as the first initial angle to control the air inlet door to open at the first initial angle.

[0072] Exemplarily, Table 1 shows a corresponding relationship between an actual distance L and a first initial angle α of the air inlet damper.

[0073] Table 1

[0074] L(cm) α 15cm 20° 20cm 40° 25cm 65° 30cm 90°

[0075] The method provided by the embodiment of the present disclosure enables the drawer of the refrigerator to be arranged below the storage shelf and the capacity can be adjusted as the height of the storage shelf changes, so that the drawer capacity can be flexibly changed; and the opening angle of the air inlet door can be controlled according to the actual distance between the storage shelf and the bottom of the drawer, so that the supplied cooling capacity can be matched with the cooling capacity demand corresponding to the actual capacity of the drawer, ensuring more accurate temperature control and reducing the energy consumption of the refrigerator.

[0076] Combination Figure 6 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0077] S10, the control device obtains the actual distance between the storage rack and the bottom of the drawer.

[0078] S21, the control device controls the air inlet damper to open at a first initial angle according to the correspondence between the actual distance and the opening angle of the air inlet damper, and the control device controls the main damper to open at a second initial angle according to the correspondence between the actual distance and the opening angle of the main damper.

[0079] Here, the actual distance is positively correlated with the opening angle of the total air door. The larger the actual distance is, the larger the opening angle of the total air door is. In this way, the total cooling capacity delivered by the air supply duct is increased to meet the cooling capacity demand of the drawer as much as possible.

[0080] The correspondence between the actual distance and the opening angle of the total air door can be in the form of a one-to-one correspondence data table. In this case, the correspondence between the actual distance and the opening angle of the total air door can be stored in a database in advance. After obtaining the actual distance between the shelf and the bottom of the drawer, the corresponding opening angle of the total air door can be obtained by querying the database, and the opening angle is used as the second initial angle to control the total air door to open at the second initial angle.

[0081] Exemplarily, Table 2 shows a corresponding relationship between an actual distance L and a second initial angle β of the total air door.

[0082] Table 2

[0083]

[0084]

[0085] The method provided in the embodiment of the present disclosure can control the opening angle of the air inlet damper and the opening angle of the main damper according to the actual distance between the storage rack and the bottom of the drawer, so that the cooling capacity obtained by the drawer matches its capacity as much as possible, thereby improving the accuracy of temperature control inside the drawer.

[0086] In some embodiments, after controlling the air inlet damper to open at the first initial angle and controlling the main damper to open at the second initial angle, the method further includes:

[0087] The control device acquires the actual temperature of the drawer.

[0088] When the actual temperature of the drawer is greater than the set temperature, the control device controls the opening angle of the air inlet door to increase by a preset amplitude.

[0089] After controlling the opening angles of the air inlet damper and the main damper, the control device obtains the actual temperature of the drawer to learn whether the temperature of the drawer drops to a required temperature.

[0090] Optionally, a temperature sensor is provided below the air inlet of the drawer, and the actual temperature of the drawer is detected by the temperature sensor. The control device receives the temperature data detected by the temperature sensor capable of wireless communication therewith, and takes it as the actual temperature of the drawer.

[0091] When the actual temperature of the drawer is greater than the set temperature, it is considered that the actual temperature of the drawer is still high and does not meet the temperature requirement for storing items. After adjusting the air inlet damper and the main damper, if the actual temperature of the drawer is still greater than the set temperature, the control device controls the opening angle of the air inlet damper to increase by a preset amplitude to increase the cooling capacity entering the drawer.

[0092] Optionally, the set temperature is -20° C. to 5° C. When the actual temperature of the drawer is greater than the set temperature, it is not conducive to preserving the items in the drawer.

[0093] Optionally, the preset range is 5° to 20°. With this preset range, the increase range of the air inlet door can be moderate, and the actual temperature in the drawer can be reduced by a suitable range.

[0094] The method provided by the embodiment of the present disclosure can, after controlling the air inlet damper and the main damper to open at their respective corresponding angles, again determine whether the actual temperature of the drawer meets the temperature requirement, that is, whether it is less than or equal to the set temperature. If it is greater than the set temperature, the opening angle of the air inlet damper is controlled to increase by a preset amplitude to increase the cooling capacity input to the drawer, so that the actual temperature of the drawer is reduced to meet the temperature requirement.

[0095] After controlling the opening angle of the air inlet door to increase by a preset amplitude, the actual temperature of the drawer is continuously obtained, and when the actual temperature of the drawer is greater than the set temperature, the opening angle of the air inlet door is continuously controlled to increase by a preset amplitude. This step can be repeated until the actual temperature of the drawer is less than or equal to the set temperature.

[0096] Combination Figure 7 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0097] S10, the control device obtains the actual distance between the storage rack and the bottom of the drawer.

[0098] S21, the control device controls the air inlet damper to open at a first initial angle according to the correspondence between the actual distance and the opening angle of the air inlet damper, and the control device controls the main damper to open at a second initial angle according to the correspondence between the actual distance and the opening angle of the main damper.

[0099] S30, the control device obtains the actual temperature of the drawer.

[0100] S40, when the actual temperature of the drawer is greater than the set temperature, the control device controls the opening angle of the air inlet door to become α2, α2=α1+△α, α1 is the first initial angle.

[0101] Here, α2 is α1 plus Δα. The opening angle of the air inlet damper can be controlled by controlling the number of steps of the stepping motor driving the flipping of the air inlet damper. Optionally, Δα>0.

[0102] Exemplarily, the first initial angle of the air inlet damper is 45°. When the actual temperature of the drawer is greater than the set temperature, the control device controls the opening angle of the air inlet damper to increase by 5° on the basis of 45° to 50°.

[0103] The method provided in the embodiment of the present disclosure first controls the opening angles of the air inlet damper and the main damper according to the actual distance. When the actual temperature of the drawer is greater than the set temperature, the opening angle of the air inlet damper is further controlled to increase by an amplitude of △α to increase the cooling capacity delivered to the drawer, thereby further reducing the actual temperature of the drawer.

[0104] In some embodiments, after step S40, the method further includes:

[0105] The control device acquires the actual temperature of the drawer.

[0106] When the actual temperature of the drawer is greater than the set temperature, the control device controls the opening angle of the air inlet door to become α3, where α3=α2+Δα.

[0107] If the opening angle of the air inlet damper is adjusted multiple times, each adjustment increases the preset amplitude based on the angle of the air inlet damper after the last adjustment.

[0108] The method for controlling a refrigerator provided in an embodiment of the present disclosure continues to control the opening angle of the air inlet door to increase by a preset amplitude △α if the actual temperature of the drawer is greater than the set temperature, after the opening angle of the air inlet door is previously controlled to increase, so as to increase the cooling capacity provided to the drawer, so as to further reduce the actual temperature of the drawer until the actual temperature of the drawer drops below the set temperature.

[0109] In some embodiments, when the actual temperature of the drawer is greater than the set temperature, the method further includes:

[0110] The control device controls the opening angle of the total air door to increase by a first set amplitude.

[0111] Here, the opening angle of the total air door is also controlled to increase so that the total cooling capacity in the air supply duct is increased, further improving the supply of cooling capacity to the drawer, so as to reduce the drawer temperature to below the set temperature with fewer adjustments as much as possible.

[0112] Optionally, the first setting amplitude is 5° to 20°. The first setting amplitude can be selected within this range in combination with the model of the refrigerator. Optionally, the first setting amplitude is 10°.

[0113] Optionally, the first set amplitude is smaller than the preset amplitude. Here, making the adjustment amplitude of the air inlet damper larger than the adjustment amplitude of the total damper is conducive to a steady temperature drop, avoiding excessive temperature drop, and improving the accuracy of temperature control.

[0114] When the embodiment of the present disclosure subsequently detects that the actual temperature of the drawer is still greater than the set temperature, the opening angle of the total air door is controlled to increase by a first set amplitude to increase the total cooling capacity in the air inlet duct, thereby further increasing the cooling capacity provided to the drawer and trying to reduce the actual temperature of the drawer to below the set temperature.

[0115] In some embodiments, when the actual temperature of the drawer is greater than the set temperature, the method further includes:

[0116] The control device controls the rotation speed of the fan for delivering air flow to the air supply duct to increase by a first amplitude.

[0117] Here, controlling the speed of the fan to increase by the first amplitude can speed up the flow rate of the airflow in the air supply duct, further increasing the cooling capacity delivered to the drawer. By controlling the opening angle of the air inlet damper to increase, the opening angle of the main damper to increase, and the speed of the fan to increase, the actual temperature of the drawer can be reduced to below the set temperature in a relatively short time.

[0118] Combination Figure 8 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0119] S10, the control device obtains the actual distance between the storage rack and the bottom of the drawer.

[0120] S21, the control device controls the air inlet damper to open at a first initial angle according to the correspondence between the actual distance and the opening angle of the air inlet damper, and the control device controls the main damper to open at a second initial angle according to the correspondence between the actual distance and the opening angle of the main damper.

[0121] S30, the control device obtains the actual temperature of the drawer.

[0122] S42, when the actual temperature of the drawer is greater than the set temperature, the control device controls the opening angle of the air inlet damper to α2, α2=α1+△α, controls the opening angle of the main damper to β2, β2=β1+△β1, and controls the speed of the fan used to deliver air flow to the air supply duct to v2, v2=v1+△v1.

[0123] Among them, α1 is the first initial angle, △α is the preset amplitude, β1 is the second initial angle, △β1 is the first set amplitude, and △v1 is the first amplitude.

[0124] Optionally, △v1=200r / min~400r / min. Optionally, △v1=340r / min~350r / min. Exemplarily, △v1=345r / min. Optionally, the maximum speed of the fan is 1380r / min.

[0125] The method provided by the embodiment of the present disclosure further detects the actual temperature of the drawer after adjusting the opening angles of the air inlet damper and the main damper according to the distance between the storage rack and the bottom of the drawer, and when the actual temperature of the drawer is greater than the set temperature, further controls the opening angle of the air inlet damper to increase by △α, the opening angle of the main damper to increase by △β1, and the speed of the fan to increase by △v1, thereby further reducing the actual temperature of the drawer.

[0126] In some embodiments, after the control device obtains the actual temperature of the drawer, the control device further includes:

[0127] When the actual temperature of the drawer is less than or equal to the set temperature, the control device obtains the actual temperature of the refrigerator compartment;

[0128] When the actual temperature of the refrigerating chamber is greater than the preset temperature, the control device obtains the current angle of the main air door;

[0129] The control device controls the opening angle of the total air door to increase by a second set amplitude based on the current angle.

[0130] In the embodiment of the present disclosure, the drawer is arranged in the refrigerator, and the air supply duct is connected to both the drawer and the refrigerator. When the actual temperature of the drawer is less than or equal to the set temperature, the actual temperature of the refrigerator continues to be obtained. When the actual temperature of the drawer is less than or equal to the set temperature, it indicates that the actual temperature of the drawer has met the temperature requirement for storing items, and then the supply of cooling capacity to the refrigerator is adjusted.

[0131] Optionally, a temperature sensor is provided at the air inlet of the refrigerating chamber. The actual temperature of the refrigerating chamber is detected by the temperature sensor. The control device communicates with the temperature sensor wirelessly to receive temperature data detected by the temperature sensor as the actual temperature of the refrigerating chamber.

[0132] The embodiment of the present disclosure obtains the actual temperature of the cold storage room and compares the actual temperature of the cold storage room with the preset temperature. When the actual temperature of the cold storage room is greater than the preset temperature, it indicates that the temperature of the cold storage room does not meet the temperature requirement for storing items, and therefore the refrigeration capacity delivered to the cold storage room needs to be adjusted.

[0133] The control device obtains the current angle of the total air door, and increases it by a second set amplitude based on the current angle. In this way, the total cooling capacity delivered by the air supply air door can be increased, thereby increasing the cooling capacity received by the refrigerator compartment and reducing the temperature.

[0134] In some embodiments, when the actual temperature of the refrigerating chamber is greater than the preset temperature, the method further includes:

[0135] The control device obtains the current rotation speed of the fan used to deliver air flow to the air supply duct;

[0136] The control device controls the rotation speed of the fan to increase by a second amplitude based on the current rotation speed.

[0137] In the embodiment of the present disclosure, when the actual temperature of the cold storage room is greater than the preset temperature, in addition to adjusting the opening angle of the main air door, the current speed of the fan is controlled to increase. In this way, the cooling capacity delivered by the air supply duct to the cold storage room can be further improved, so that the temperature of the cold storage room can be reduced as soon as possible.

[0138] Combination Fig. 9 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0139] S10, the control device obtains the actual distance between the storage rack and the bottom of the drawer.

[0140] S21, the control device controls the air inlet damper to open at a first initial angle according to the correspondence between the actual distance and the opening angle of the air inlet damper, and the control device controls the main damper to open at a second initial angle according to the correspondence between the actual distance and the opening angle of the main damper.

[0141] S30, the control device obtains the actual temperature of the drawer.

[0142] S33, the control device determines whether the actual temperature of the drawer is greater than the set temperature, if so, executes step S42; if not, executes step S43.

[0143] S42, when the actual temperature of the drawer is greater than the set temperature, the control device controls the opening angle of the air inlet damper to α2, α2=α1+△α, controls the opening angle of the main damper to β2, β2=β1+△β1, and controls the speed of the fan used to deliver air flow to the air supply duct to v2, v2=v1+△v1.

[0144] S43, the control device obtains the actual temperature of the refrigerating chamber.

[0145] S51, when the actual temperature of the refrigerating chamber is greater than the preset temperature, the control device obtains the current angle β' of the main air door and the current rotation speed v' of the fan for delivering air flow to the air supply duct.

[0146] S61, the control device controls the opening angle of the total air door to become β", β" = β' + △ β2, and controls the speed of the fan to become v", v" = v' + △ v2.

[0147] Among them, △β2 is the second set amplitude, and △v2 is the second amplitude.

[0148] When adjusting the temperature of the refrigerator compartment, the embodiment of the present disclosure increases the opening angle of the total air door by △β2 compared with the current angle, and increases the speed of the fan by △v2 compared with the current wind speed, so that the temperature of the refrigerator compartment drops below the preset temperature.

[0149] The method provided in the embodiment of the present disclosure adjusts the refrigeration capacity delivered to the drawer after adjusting the refrigeration capacity delivered to the refrigerator, so that the refrigeration capacity delivered by the refrigerator to the drawer and the refrigerator can be more accurate, the temperature control of the drawer and the refrigerator can be more precise, the preservation effect of the drawer is improved, and the energy consumption of the refrigerator is reduced.

[0150] Optionally, 0<△β2≤△β1, 0<△v2≤△v1. The second setting amplitude can be the same as the first setting amplitude, or it can be smaller than the first setting amplitude; the second amplitude can be the same as the first amplitude, or it can be smaller than the first amplitude. After adjusting the cooling capacity delivered to the drawer, the adjustment amplitude of the opening angle of the total air door can be relatively reduced, and the adjustment amplitude of the fan speed can also be relatively reduced, so as to avoid a significant impact on the actual temperature of the drawer when adjusting the total air door opening angle and the fan speed.
