[0059] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0060] As people's living standards improve, users have higher and higher requirements for the quality of frozen food preservation. For freezers, the requirements for adjustable freezing volume and freezing depth are also constantly increasing. Users require that the deep freezing temperature and deep freezing volume be adjustable.

[0061] However, in order to ensure the cryogenic temperature, the existing refrigerator sets the cryogenic volume to a fixed volume, which does not meet the user's demand for the cryogenic space volume and temperature to be adjustable at the same time.

[0062] Therefore, how to ensure the cryogenic temperature while satisfying the requirement of adjustable cryogenic space volume is a problem to be solved urgently in the art.

[0063] Combination Figures 1 to 10As shown, the disclosed embodiment provides a cold cabinet 20, a method for controlling the air supply volume of the cold cabinet 20, and a device for controlling the air supply volume of the cold cabinet 20. The cold cabinet 20 includes a heat preservation partition 21 and an air duct baffle 24. The heat preservation partition 21 divides the refrigeration space of the cold cabinet 20 into a deep cold space 22 and a variable temperature space 23; the heat preservation partition 21 can move in the deep cold space 22 and the variable temperature space 23 to change the volume of the deep cold space 22; the air duct baffle 24 can be movably arranged at the air supply port 26 of the deep cold space 22 to adjust the air supply volume of the deep cold space 22 by adjusting the size of the air supply area of ​​the air supply port 26; the relationship between the air supply volume of the deep cold space 22 and the air supply area and the volume of the deep cold space includes: V=b1X-b2; F=a1X-a2; V is the volume of the deep cold space, in L; X is the air supply volume of the deep cold space 22, in L / min; F is the air supply area of ​​the air supply port 26, in mm 2 ; a1, a2, b1, b2 are all constants, and the value range of a1 is 8.9 to 9.2; the value range of a2 is 612 to 621; the value range of b1 is 0.19 to 0.21; the value range of b2 is 0.5 to 0.7.

[0064] like Figure 1 , Figure 3 and Figure 4 As shown, the heat preservation partition 21 divides the refrigerator 20 from top to bottom into a variable temperature space 23 located at the top and a deep cold space 22 located at the bottom. The heat preservation partition 21 can move in the vertical direction relative to the refrigerator 20. When the heat preservation partition 21 moves upward, the volume of the deep cold space 22 located at the bottom becomes larger; a plurality of air supply ports 26 are arranged below the heat preservation partition 21, and a movable air duct baffle 24 blocks a plurality of air supply ports 26 at the same time. The movable air duct baffle 24 is arranged on the back of the air duct cover 30, and can move up and down relative to the air supply ports 26 to change the shielding area of ​​the air supply ports 26, so as to adjust the temperature of the deep cold space 22. The relationship between the air supply volume of the deep cold space 22 and the air supply area and the volume of the deep cold space includes:

[0065] V=b1X-b2; (1)

[0066] F=a1X-a2; (2)

[0067] Wherein, V is the volume of the cryogenic space, in L; X is the air volume of the cryogenic space 22, in L / min; F is the air supply area of ​​the air supply port 26, in mm 2a1, a2, b1 and b2 are all constants greater than zero. The larger the air supply area of ​​the air supply port 26, the larger the air supply volume entering the deep cold space 22 per minute will be, and the temperature reduction speed of the deep cold space 22 will also be accelerated, thereby achieving quick freezing. When the volume of the deep cold space is changed by adjusting the insulation partition, the required air supply volume is determined by the change in volume, and the air supply area of ​​the air supply port is determined by adjusting the air duct baffle according to the required air supply volume to meet the air supply volume demand of the refrigeration space.

[0068] Optionally, preferred values ​​of a1 include: 8.9218, 9.1325; preferred values ​​of a2 include: 612.15, 620.85; preferred values ​​of b1 include: 0.196, 0.205; preferred values ​​of b2 include: 0.5345, 0.6821.

[0069] Table 1 below shows the relationship between the volume of the cryogenic space 22 , the air supply volume, and the air supply area of ​​the air supply port 26 .

[0070] Table 1

[0071]

[0072] It can be seen that as the air supply area increases, the air supply volume increases linearly, which is consistent with the result calculated by the above formula (1).

[0073] Optionally, the refrigerator 20 further includes a damper 25 rotatably disposed at the air outlet 26 , and the damper 25 can rotate 90 degrees relative to the air outlet 26 between an open position to open the air outlet 26 and a closed position to block the air outlet 26 .

[0074] like Figure 2 As shown, in some embodiments, an air supply outlet 26 is opened on the upper inner wall of the deep cold space 22 below the heat-insulating partition 21, and the air supply outlet 26 is provided with a damper 25. One side end of the damper 25 is rotatably connected to the side wall of the air supply outlet 26 through a door shaft. The damper 25 can rotate around the door shaft relative to the air supply outlet 26 to adjust the area of ​​the air supply outlet 26 blocked by the damper 25 to adjust the air supply volume.

[0075] Optionally, the refrigerator 20 also includes a guide post handle 27 and an air duct cover 30, the guide post handle 27 is connected to the air duct baffle 24; the air duct cover 30 is covered on the air duct 43 of the refrigerator 20, and the air duct cover 30 is provided with an air duct opening 31 and a guide groove 32; the air duct baffle 24 is correspondingly arranged at the air duct opening 31, and the guide post handle 27 is correspondingly arranged at the guide groove 32, and the guide post handle 27 moves along the guide groove 32 to drive the air duct baffle 24 to move to adjust the area of ​​the air duct baffle 24 blocking the air duct opening 31.

[0076] Combined with 1. Figure 3 and Figure 4As shown, the duct baffle 24 is provided with a guide post handle 27, and the duct cover 30 is provided with a guide groove 32 adapted to the guide post handle 27, the guide groove 32 extends from top to bottom, the guide post handle 27 is integrated with the duct baffle 24, the guide post handle 27 moves in the vertical direction, and the duct baffle 24 moves in the vertical direction to block the duct opening 31. Among them, the duct opening 31 is opened on the duct cover 30, connecting the air duct 43 and the refrigeration space, the duct baffle 24 is installed on the duct cover 30, and the duct baffle 24 can move relative to the duct cover 30, and the duct baffle 24 is provided with a baffle at the position corresponding to the duct opening 31 to block the duct opening 31, and the duct baffle 24 moves to control the baffle to block the duct opening 31 or open the duct opening 31. The duct opening 31 includes but is not limited to the air supply port 26, and the duct opening 31 may also include other vents, which can be set as needed.

[0077] It can be understood that in the above embodiment, the air duct opening 31 can also include a return air opening, and the air duct baffle 24 can control the air volume in the refrigeration space by blocking the return air opening.

[0078] Optionally, the refrigerator further includes a refrigeration system 1, which uses a mixed refrigerant, and the mixed refrigerant includes one of R600a, R600 and R290.

[0079] The refrigeration system 11 includes a compressor 10, an evaporator 42 and a condenser in sequence through a pipeline. The refrigeration system 11 is used to refrigerate the cabinet. The cabinet defines a refrigeration space, and the refrigeration space includes a deep cold space 22 with a volume of V. The temperature adjustment range of the deep cold space 22 is -28°C to 40°C, for example, -28°C, -35°C or -40°C, covering the functions of ordinary freezing and deep freezing, and adapting to the needs of users. The mixed refrigerant can be composed of R600a and R290, or it can be composed of R600 and R290. The mass proportion of various single refrigerants (R600a, R600 or R290) in the mixed refrigerant affects the temperature pulling depth of the mixed refrigerant. The deep cold space 22 is the space with the lowest temperature required in the refrigeration space and the space with the largest cooling demand in the refrigeration space. Therefore, when designing the mass proportion of various single refrigerants in the mixed refrigerant, the parameters of the deep cold space 22 are the most important considerations. Among the parameters of the cryogenic space 22, when the required temperature of the cryogenic space 22 is determined, the volume V of the cryogenic space 22 determines the amount of cooling required by the cryogenic space 22. The cooling required by the cryogenic space 22 can only be met when the mass proportions of various single-substance refrigerants in the mixed refrigerant meet the requirements. Therefore, the mass proportions of various single-substance refrigerants in the mixed refrigerant are affected by the volume V of the cryogenic space 22. In most cases, when the temperature in the cryogenic space 22 meets the standard, the temperatures of other spaces in the refrigeration space can also meet the standard. Therefore, only the volume of the cryogenic space 22 is used to determine the mass proportions of various single-substance refrigerants in the mixed refrigerant, and the parameters of other spaces in the refrigeration space except the cryogenic space 22 are ignored. In actual applications, the type of refrigerant used can be adjusted according to the requirements of the refrigeration depth to achieve the comprehensive needs of energy-saving refrigeration.

[0080] In some embodiments, when the volume of the refrigeration space is 150 L, the mass proportions of R600a and R290 are 70% and 30% respectively.

[0081] In some embodiments, when the volume of the refrigeration space is 198 L, the mass proportions of R600a and R290 are 65% and 35% respectively.

[0082] In some embodiments, when the volume of the refrigeration space is 150 L, the mass proportions of R600 and R290 are 60% and 40% respectively.

[0083] In some embodiments, when the volume of the refrigeration space is 198 L, the mass proportions of R600 and R290 are 55% and 45% respectively.

[0084] Optionally, the relationship between the mass proportion of R290 in the mixed refrigerant and the volume of the cryogenic space includes:

[0085] W=1-[k1*V 2 -k2*V+k3]; (3)

[0086] Among them, W is the mass proportion of R290; V is the volume of the deep cold space; the value range of k1 is 0.000007 to 0.000009; the value range of k2 is 0.003 to 0.004; when the mixed refrigerant is a mixture of R600 and R290, the corresponding value range of k3 is 0.9 to 1; when the mixed refrigerant is a mixture of R600a and R290, the corresponding value range of k3 is 1 to 1.1.

[0087] It should be noted that the unit of the volume V of the cryogenic space 22 in the above formula (3) is L, and only the value of the volume V when L is used as the unit is used in the calculation.

[0088] From the above formula (3), it can be seen that when the mixed refrigerant is composed of R600a and R290, the mass proportion of R600a is (k1*V 2 -k2*V+k3), which is a parabola opening upward.

[0089] In this way, as the volume V of the deep cold space 22 increases, the mass proportion of R600a first decreases and then increases, and the refrigeration proportion of R290 first increases and then decreases.

[0090] Compared with R600a, R290 is more helpful to achieve the low temperature of the deep cold space 22, and the larger the volume V of the deep cold space 22, the greater the cold capacity required by the deep cold space 22, so the mass proportion of R290 increases first. Since the exhaust pressure of the compressor 10 is large when the refrigeration system 11 adopts R290, therefore, as the mass proportion of R290 increases, the exhaust pressure required by the compressor 10 becomes larger and larger, which will cause the compressor 10 to be unable to meet the needs, and when the mass proportion of R290 increases to a certain extent, adding R290 will not have much effect on reducing the temperature of the deep cold space 22. Therefore, the mass proportion of R290 will not be controlled to increase all the time. After increasing to a certain extent, the mass proportion of R290 is controlled to start to decrease, and finally reach a low temperature that can meet the low temperature required by the deep cold space 22 and protect the compressor 10 to avoid damage to the compressor 10.

[0091] Similarly, from the above formula (3), when the mixed refrigerant is composed of R600 and R290, the mass proportion of R600 is (k1*V 2 -k2*V+k3), which is a parabola opening upward.

[0092] In this way, as the volume V of the deep cold space 22 increases, the mass proportion of R600 first decreases and then increases, and the refrigeration proportion of R290 first increases and then decreases.

[0093] Compared with R600, R290 is more helpful to achieve the low temperature of the deep cold space 22, and the larger the volume V of the deep cold space 22, the greater the cold capacity required by the deep cold space 22, so the mass proportion of R290 increases first. Since the exhaust pressure of the compressor 10 is large when the refrigeration system 1 adopts R290, as the mass proportion of R290 increases, the exhaust pressure required by the compressor 10 becomes larger and larger, which will cause the compressor 10 to fail to meet the demand. Therefore, the mass proportion of R290 will not be controlled to increase all the time. After increasing to a certain extent, the mass proportion of R290 is controlled to begin to decrease, and finally reach a low temperature that can meet the low temperature required by the deep cold space 22 and protect the compressor 10 to avoid damage to the compressor 10.

[0094] Similarly, from the above formula (3), when the mixed refrigerant is composed of R600a, R600 and R290, the total mass proportion of R600a and R600 is (k1*V 2 -k2*V+k3), which is a parabola opening upward, and ultimately reaches a low temperature that can meet the low temperature required by the cryogenic space 22 and protect the compressor 10 to avoid damage to the compressor 10.

[0095] Compared with R600a, R600 has the characteristics of small refrigeration capacity and low exhaust pressure of the compressor 10, that is, R600 has lower performance requirements for the compressor 10. Therefore, when the volume V of the refrigeration space is constant, more R290 can be allowed to exist in the mixed refrigerant of R600 and R290, that is, the refrigeration proportion of R290 can be larger, so k3 is small.

[0096] Optionally, when the mixed refrigerant is a mixture of R600a and R290, the corresponding k3 is greater than 1. When the mixed refrigerant is a mixture of R600 and R290, the corresponding k3 is less than 1.

[0097] Table 2 below shows the relationship between the volume of the cryogenic space 22, the total volume of the refrigeration space, the mass proportion of R600, the mass proportion of R290, the cooling capacity W, the casing temperature of the compressor 10, the exhaust temperature of the compressor 10, the exhaust pressure of the compressor 10, the suction pressure of the compressor 10, the refrigeration depth of the cryogenic space 22, the refrigeration depth of the variable temperature space 23, power consumption and noise, wherein the refrigeration fan speed is constant and the air supply area is constant.

[0098] Table 2

[0099]

[0100] It can be seen that when the volume of the refrigeration space is 150L, ​​the comprehensive indexes of power consumption, noise, and refrigeration depth of the deep refrigeration space 22 are optimal when the mass proportions of R600a and R290 are 70% and 30% respectively. This is consistent with the result calculated by the above formula (3).

[0101] When the volume of the refrigeration space is 198L, and the mass proportions of R600a and R290 are 65% and 35% respectively, the comprehensive indexes of power consumption, noise, and refrigeration depth of the deep refrigeration space 22 are optimal. This is consistent with the result calculated by the above formula (3).

[0102] Table 3 below shows the relationship between the volume of the cryogenic space 22, the volume of the refrigeration space, the mass proportion of R600, the mass proportion of R290, the cooling capacity W, the casing temperature of the compressor 10, the exhaust temperature of the compressor 10, the exhaust pressure of the compressor 10, the suction pressure of the compressor 10, the refrigeration depth of the cryogenic space 22, the refrigeration depth of the variable temperature space 23, the power consumption and the noise. Among them, the refrigeration fan speed is constant and the air supply area is constant.

[0104]

[0105]

[0106] It can be seen that when the volume of the refrigeration space is 150L, ​​the mass proportions of R600 and R290 are 60% and 40% respectively, and the comprehensive indexes of power consumption, noise, and refrigeration depth of the deep refrigeration space 22 are optimal. This is consistent with the result calculated by the above formula (3).

[0107] When the volume of the refrigeration space is 198L, and the mass proportions of R600 and R290 are 55% and 45% respectively, the comprehensive indexes of power consumption, noise, and refrigeration depth of the deep refrigeration space 22 are optimal. This is consistent with the result calculated by the above formula (3).

[0108] Optionally, the refrigeration space also includes a variable temperature space 23, and the temperature adjustment range of the variable temperature space 23 is 8 to 26°C, and the temperature range covers refrigeration function, ice temperature, and freezing function.

[0109] Setting the variable temperature space 23 can enrich the refrigeration temperature range of the freezer 20. The combination of the variable temperature space 23 and the deep freezing space 22 can realize various application scenarios such as refrigeration + freezing, ice temperature + freezing, ice temperature + deep freezing, freezing + freezing, freezing + deep freezing, etc., which can meet users' different functional requirements.

[0110] Optionally, the temperature-changing space 23 is located above the cryogenic space 22. It can be understood that the temperature-changing space 23 is located below the cryogenic space 22, or the temperature-changing space 23 and the cryogenic space 22 are arranged in the left-right direction.

[0111] Optionally, combined Figure 6 , Fig. 9 and Fig.10 , the refrigerator 20 includes a refrigeration system 1, a control system and a regulating device.

The regulating device includes a mixed refrigerant storage device and a pipeline and a valve connected to the refrigeration system 1, wherein different refrigerants are independently stored in the mixed refrigerant storage device, and each refrigerant is configured with an independent pipeline and a valve connected to the refrigeration system 1 to separately transport or extract refrigerant to the refrigeration system 1 to change the refrigerant ratio in the refrigeration system 1. Among them, the pipeline is provided with a filtering device, and the filtering device is adapted to the valve to realize that a single refrigerant is transported from the regulating device to the refrigeration system 1 or a refrigerant is extracted from the refrigeration system 1 to the regulating device.

[0112] Optionally, the compressor 10 is a variable frequency compressor 10 .

[0113] The variable frequency compressor 10 can automatically control the speed of the compressor 10 according to different ambient temperatures and the set temperature of the refrigeration space (including the deep cold space 22 and the variable temperature space 23), thereby achieving refrigeration performance while also effectively improving power consumption and noise indicators.

[0114] Optionally, the refrigerator 20 further includes a refrigeration system 1 , a heat-insulating partition 21 , a first damper group 33 and a second damper group 34 . A refrigeration system 1 adopts a mixed refrigerant, which includes at least one of R600a and R600 and R290; a heat-insulating partition 21 divides the refrigeration space of a refrigerator 20 into a deep cold space 22 and a variable temperature space 23; the heat-insulating partition 21 can move between a first position 50 in which the volume of the deep cold space 22 is V1 and a second position 51 in which the volume of the deep cold space 22 is V2, wherein V1 is greater than V2; a first damper group 33, corresponding to when the heat-insulating partition 21 is in the first position 50, the refrigerator 20 assists in sending back air; a second damper group 34, corresponding to when the heat-insulating partition 21 is in the second position 51, the refrigerator 20 assists in sending back air; and, when the volume of the deep cold space 22 is V1, the mixed refrigerant is adjusted to a first ratio; when the volume of the deep cold space 22 is V2, the mixed refrigerant is adjusted to a second ratio.

[0115] like Figure 1 to Figure 2As shown, the freezer 20 uses a mixed refrigerant, and the cold is delivered to the first damper group 33 and the second damper group 34 through the evaporating fan 44. The heat-insulating partition 21 can move in the vertical direction to adjust the volume of the deep cold space 22 located below, so that the volume of the deep cold space 22 can be adjusted. When the heat-insulating partition 21 moves upward, the volume of the deep cold space 22 increases, and the volume of the variable temperature space 23 located above decreases. The deep cold space 22 and the variable temperature space 23 each use an independent refrigeration system 1. The deep cold space 22 uses a mixed refrigerant. When the heat-insulating partition 21 is located at the first position 50, the volume of the deep cold space 22 increases, and the first damper group 33 corresponds to the deep cold space 22, and assists in sending back air to the deep cold space 22; at this time, in order to ensure the temperature and cooling speed of the deep cold space 22, the mixed refrigerant is adjusted to the first ratio to meet the cooling speed and temperature. When the insulation partition 21 is located at the second position 51, the volume of the cryogenic space 22 is reduced, and the second air door group 34 corresponds to the cryogenic space 22 to assist in returning air to the cryogenic space 22; the mixed refrigerant is adjusted to the first ratio to maximize energy saving while meeting the refrigeration temperature and refrigeration speed of the cryogenic space 22.

[0116] Optionally, the first air door group 33 includes: an auxiliary air supply air door 35, which is adjacent to the first position 50 and is arranged on the top inner liner side wall of the deep cold space 22; a first auxiliary return air door 36, which is adjacent to the first position 50 and is arranged on the bottom inner liner side wall of the variable temperature space 23; the second air door group 34 includes: a second auxiliary return air door 37, which is adjacent to the second position 51 and is arranged on the bottom inner liner side wall of the variable temperature space 23.

[0117] like Figure 4 As shown, the heat preservation partition 21 is installed at the first position 50, and the auxiliary air supply damper 35 is located below the heat preservation partition 21 and adjacent to the heat preservation partition 21, and is arranged on the side wall of the inner liner of the refrigerator 20, so that the cold air can be transported to the deep cold space 22 through the auxiliary air supply damper 35. The first auxiliary return air damper 36 is arranged at the bottom of the variable temperature space 23 above the heat preservation partition 21 at the first position 50. When the heat preservation partition 21 is installed at the first position 50, the volume of the variable temperature space 23 becomes smaller, and the return air port of the original variable temperature space 23 is separated by the heat preservation partition 21. At this time, the first auxiliary return air damper 36 is opened, so that the cold air in the variable temperature space 23 can be output at the first auxiliary return air damper 36 at the bottom of the variable temperature space 23, so that the cold air can fill the entire space of the variable temperature space 23. When the insulation partition 21 is located at the second position 51, the volume of the variable temperature space 23 expands downward. At this time, the second auxiliary return air damper 37 is located at the bottom of the variable temperature space 23, so that the cold air in the variable temperature space 23 can flow out when it reaches the second auxiliary return air damper 37, so that the cold air remains in the variable temperature space 23 and fills the variable temperature space 23 from top to bottom.

[0118] Optionally, the refrigerator 20 further includes a first air supply damper group 38 and a second air supply damper group 39. The first air supply damper group 38 is disposed on the upper side wall of the temperature variable space 23; the second air supply damper group 39 is disposed on the upper side wall of the deep cold space 22 and below the second position 51.

[0119] like Figure 4 As shown, the first air supply damper group 38 is used to supply air to the variable temperature space 23, and is arranged on the upper side wall of the variable temperature space 23 so that cold air can be transported from the upper part into the variable temperature space 23; the second air supply damper group 39 is arranged in the deep cold space 22, and is located on the upper side wall of the deep cold space 22 below the second position 51. In this way, when the insulation partition 21 is installed in the second position 51, cold air is input into the upper part of the deep cold space 22 by the second air supply damper group 39, and flows downward to fill the entire deep cold space 22.

[0120] Optionally, the refrigerator 20 is provided with slideways 40 on both inner walls of the first position 50 and the second position 51 on opposite sides;

[0121] Matching slideways 4140 are provided at the two ends of the heat-insulating partition 21 corresponding to the slideways 40 , so that the heat-insulating partition 21 can be slidably and sealedly installed on the refrigerator 20 .

[0122] like Figure 3 , Figure 4 and Figure 7 As shown, the slide 40 is arranged on the opposite side walls of the inner tank of the refrigerator 20, and the two side ends of the insulation partition 21 are provided with matching slides 4140. The matching slides 4140 cooperate with the slide 40 to realize the sliding of the insulation partition 21, and a sealing structure is provided at the matching position of the insulation partition 21 and the slide 40, so that the temperature variable space 23 above the insulation partition 21 and the deep cold space 22 below the insulation partition 21 are sealed and isolated.

[0123] Optionally, the cold cabinet 20 also includes: an evaporator 42, which is arranged in a compressor compartment at the bottom of the deep cold space 22; an air duct 43, which connects the evaporator 42 and each damper 25; and an evaporating fan 44, which is arranged between the evaporator 42 and the air duct 43, and is used to transport the cold energy of the evaporator 42 to the air duct 43.

[0124] like Figure 4 and Figure 7 As shown, the evaporator 42 is arranged at the bottom of the deep cold space 22, the evaporating fan 44 is arranged corresponding to the evaporator 42, and the air outlet direction of the evaporating fan 44 corresponds to the air duct opening 31. The evaporating fan 44 blows the cold energy of the evaporator 42 to each air door 25 through the air duct 43 to provide cooling for each refrigeration compartment.

[0125] Optionally, the refrigerator 20 further includes: a magnetic switch 45 , which controls the switch state of each damper 25 .

[0126] like Figure 4As shown, the magnetic switch 45 is connected to the damper 25 and the controller, and is controlled to open and close the damper 25 to cooperate with the installation of the thermal insulation partition 21.

[0127] Combination Figure 1 , Figure 5 , Figure 6 , Figure 7 ,and Fig.10 As shown, in some embodiments, a method for controlling the air supply volume of a refrigerator is provided, which is used in a refrigerator as in any one of the above embodiments, and the control method includes:

[0128] S701, obtaining the volume information of the cryogenic space.

[0129] S702: Control the air supply area of ​​the air supply port according to the volume information of the cryogenic space to adjust the air supply volume of the cryogenic space.

[0130] like Figure 1 , Figure 3 and Figure 4 As shown, in the disclosed embodiment, the heat preservation partition 21 divides the refrigerator 20 from top to bottom into a variable temperature space 23 located at the top and a deep cold space 22 located at the bottom. The heat preservation partition 21 can move in the vertical direction relative to the refrigerator 20. When the heat preservation partition 21 moves upward, the volume of the deep cold space 22 located at the bottom increases. When the heat preservation partition 21 moves downward, the volume of the deep cold space 22 located at the bottom decreases. The heat preservation partition 21 can move in the vertical direction relative to the refrigerator 20 to change the volume of the inner liner of the refrigerator 20. As the volume of the inner liner of the refrigerator 20 changes, the original air supply volume cannot meet the refrigeration demand of the deep cold space 22. Therefore, it is necessary to adjust the air supply volume input per minute in the deep cold space 22 to meet the temperature of the deep cold space 22 to the required temperature. When the heat preservation partition 21 moves downward, the volume of the deep cold space 22 decreases. The air outlet shielding area is adjusted to increase to reduce the air supply volume entering per minute to meet the refrigeration temperature demand in the deep cold space 22.

[0131] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the refrigerator further includes an air duct baffle 24 and an air duct cover 30. The air duct cover 30 is covered on the air duct 43. The air duct opening 31 is opened on the air duct cover 30 to connect the air duct 43 and the refrigeration space. The air duct opening 31 includes an air supply port 26, and the cold energy enters the refrigeration space from the air supply port 26. The air duct baffle 24 blocks the air duct opening 31, and the air duct baffle 24 can move relative to the air duct cover 30, so that the air duct baffle 24 moves between a blocking position of blocking the air duct opening 31 and an opening position of opening the air duct opening 31, so as to change the air supply area of ​​the air supply port 26, and then adjust the air supply volume to meet the refrigeration demand.

[0134] The refrigerator includes a heat-insulating partition that divides the refrigerator refrigeration space into a variable temperature space located at the top and a deep cold space located at the bottom. The heat-insulating partition is moved to change the volume of the deep cold space and the volume of the variable temperature space.

The air duct is moved to adjust the air duct baffle to block the air outlet to adjust the air supply area to a first air supply area, thereby controlling the air supply volume to adapt to the volume of the deep cold space.

[0141] Combination Figure 1 , Figure 5 , Figure 6 , Figure 8 ,and Fig.10As shown, the required air supply volume for the deep cold space is determined according to the volume information of the deep cold space and the relationship between the volume and the air supply volume, and the air supply area of ​​the air supply port is determined to be the first air supply area according to the relationship between the air supply volume of the deep cold space and the air supply area of ​​the air supply port; the air duct baffle is controlled to move to block the air supply port so that the air supply area of ​​the air supply port is the first air supply area to meet the air supply volume demand of the deep cold space.

[0152] In some embodiments, the refrigerator 20 includes a refrigeration system 1, a control system, and a regulating device. The refrigeration system 1 uses a mixed refrigerant, and the proportion of the components in the mixed refrigerant is adjusted by the regulating device. The regulating device includes a mixed refrigerant storage device and a pipeline and a valve connected to the refrigeration system 1, wherein different refrigerants are independently stored in the mixed refrigerant storage device, and each refrigerant is configured with an independent pipeline and a valve connected to the refrigeration system 1 to separately transport or extract refrigerant to the refrigeration system 1 to change the refrigerant ratio in the refrigeration system 1. Among them, the pipeline is provided with a filtering device, and the filtering device is adapted to the valve to realize the transport of a single refrigerant from the regulating device to the refrigeration system 1 or the extraction of a refrigerant from the refrigeration system 1 to the regulating device.

[0153] In some embodiments, a method for controlling the air supply volume of a refrigerator is provided, which is used for a refrigerator as in any one of the above embodiments, wherein the refrigerator comprises an air door and an air duct baffle, wherein the air door is rotatably arranged at the air supply port, and the air door can rotate between an air supply position of opening the air supply port and a blocking position of closing the air supply port; and the air duct baffle is movably arranged at the air supply port, and the air duct baffle can move between a position of blocking the air supply port and a position of opening the air supply port.
