[0042] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in some embodiments of the present disclosure. Obviously, the embodiments described are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0043] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" are intended to indicate that the particular features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0044] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0045] When describing some embodiments, the word "connected" and its derivatives may be used. The term "connected" should be understood in a broad sense. For example, "connected" can mean fixed connection, detachable connection, or integration; it can be directly connected or indirectly connected through an intermediate medium.

[0046] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and both include the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.

[0047] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.

[0048] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0049] As used herein, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equals is less than or equal to 5% of either one.

[0050] Refrigerators have become an indispensable household appliance in family life. To better store food, a vacuum drawer can be installed in the refrigerator. By using a vacuum device to evacuate the vacuum drawer, a vacuum space is formed inside the drawer. Storing food in the vacuum drawer isolates the food from oxygen and microorganisms, thereby extending the shelf life of the food and preventing it from spoiling.

[0051] However, to ensure the effectiveness of the vacuum environment in the vacuum drawer, the vacuum chamber of the refrigerator needs to be strictly sealed. When the vacuum chamber is in a vacuum state, the air pressure inside the vacuum chamber is lower than the air pressure outside, causing the refrigerator door to be sucked into the vacuum chamber, making it difficult to open.

[0052] To this end, some embodiments of the present disclosure provide a refrigerator 1 that controls the connection and disconnection between the inside and outside of a storage device (i.e., a vacuum drawer) through a ventilation device, so that when a user opens the storage device, the pressure difference inside and outside the storage device can be balanced, making it easier for the user to operate.

[0053] FIG1 is a perspective view of a refrigerator according to some embodiments; FIG2 is a structural view of a refrigerator with one door removed according to some embodiments.

[0054] As shown in Figures 1 and 2, a refrigerator 1 includes a housing 10, a door 11, and a refrigeration device. A storage compartment 12 is defined within the housing 10. The door 11 is connected to the front end of the housing 10 (e.g., the end of the housing 10 facing the user) and is configured to open or close the storage compartment 12. The refrigeration device is disposed within the housing 10 and is configured to supply cold air to the storage compartment 12.

[0055] The refrigerator body 10 includes an inner liner, an outer shell, and an insulation layer. The inner liner defines a storage compartment 12. The outer shell is connected to the outer surface of the inner liner to form the appearance of the refrigerator 1. The insulation layer is provided between the inner liner and the outer shell to isolate heat transfer between the storage compartment 12 and the exterior of the refrigerator 1.

[0056] In some embodiments, the inner container of the box body 10 defines a plurality of storage compartments 12. The plurality of storage compartments 12 include a refrigerating compartment and a freezing compartment located below the refrigerating compartment.

[0057] It should be noted that the arrangement of the multiple storage chambers 12 of the refrigerator 1 is not limited to the above examples. In some embodiments, the multiple storage chambers 12 may further include other compartments, and the present disclosure does not limit the arrangement of the multiple storage chambers 12.

[0058] One end of the storage chamber 12 near the door 11 is open to form an access opening 13. Thus, a user can place food into the storage chamber 12 or take food out of the storage chamber 12 through the access opening 13. The door 11 is also configured to open or close the access opening 13 of the storage chamber 12.

[0059] FIG3 is a structural diagram of a refrigerator according to some embodiments when the storage device is in a closed state; FIG4 is a structural diagram of a refrigerator according to some embodiments when the storage device is in an open state.

[0060] In some embodiments, as shown in Figures 3 and 4, the refrigerator 1 further includes a storage device 100 and an exhaust device 200. The exhaust device 200 is connected to the storage device 100 and is configured to extract gas from the storage device 100 to place the inner cavity of the storage device 100 in a vacuum state (i.e., a low-pressure state). The storage device 100 is configured to store food, etc., in a vacuum state, thereby improving the preservation effect of the food.

[0061] In some embodiments, as shown in FIG3 , the vacuum device 200 includes a vacuum pump 210. The vacuum pump 210 is connected to the storage device 100 via a connecting pipe. The vacuum pump 210 is configured to: when the vacuum device is in operation, extract the gas in the storage device 100, thereby reducing the pressure in the storage device, so that the inner cavity of the storage device 100 is in a vacuum state.

[0062] In some embodiments, the refrigerator 1 further includes a controller, which is coupled to the vacuum device 200 and configured to control the vacuum device 200 to vacuum the storage device 100 , so as to automatically vacuum the storage device 100 .

[0063] In some embodiments, the storage device 100 is disposed in a refrigerated compartment. It is understood that in some embodiments, the storage device 100 may also be disposed in other storage compartments 12, for example, in a variable temperature compartment whose refrigeration temperature range can be switched between a refrigerated temperature zone and a frozen temperature zone.

[0064] In some embodiments, as shown in FIG2 , the storage device 100 is located at the bottom of the refrigerating chamber and is disposed on the bottom wall of the refrigerating chamber.

[0065] In some embodiments, the storage device 100 is detachably connected to the housing 10. For example, the storage device 100 can be inserted into any storage chamber 12 or pulled out from any storage chamber 12.

[0066] 3 and 4 , the storage device 100 includes a housing 110 , one side of which is open to form a storage opening 111 . A storage cavity 112 is defined within the housing 110 .

[0067] In some embodiments, as shown in Figures 3 and 4, the storage device 100 includes a storage container 120 and a baffle 130. The storage container 120 is slidably connected to the shell 110. The storage container 120 can enter the storage cavity 112 through the storage opening 111, or be pulled out of the storage cavity 112 through the storage opening 111. The baffle 130 is fixedly connected to the storage container 120. The baffle 130 is configured to block the storage opening 111 when the storage container 120 is pushed into the storage cavity 112. The baffle 130 and the storage container 120 together constitute a drawer assembly 101 that can be pushed into and pulled out of the shell 110.

[0068] In some embodiments, as shown in FIG4 , the housing 110 further includes a housing rear wall 113 disposed opposite the storage opening 111. The direction along the housing rear wall 113 toward the plane where the storage opening 111 is located is referred to as a first direction (i.e., direction S1 as shown in FIG4 ), and the direction along the plane where the storage opening 111 is located toward the housing rear wall 113 is referred to as a second direction (i.e., direction S2 as shown in FIG4 ). The first direction S1 is opposite to the second direction S2. The drawer assembly 101 can be moved along the first direction S1 to be withdrawn from the housing 110, or moved along the second direction S2 to be pushed into the housing 110.

[0069] Thus, when the storage chamber 112 is blocked by the baffle 130 and the vacuum device 200 is activated, the air in the storage chamber 112 will be extracted by the vacuum device 200, placing the storage chamber 112 in a vacuum state. It will be understood that at the end of the vacuuming process, the pressure in the storage chamber 112 is lower than one standard atmospheric pressure or between one standard atmospheric pressure and absolute vacuum. Therefore, the "vacuum" mentioned in some embodiments of the present disclosure does not refer to an absolute vacuum, but is used to describe the pressure of the ambient space (such as the storage chamber 112) being lower than one standard atmospheric pressure or between one standard atmospheric pressure and absolute vacuum.

[0070] FIG5 is a cross-sectional view of a storage device of a refrigerator according to some embodiments; FIG6 is a partial enlarged view of a circled portion A in FIG5 .

[0071] 5 and 6 , the storage device 100 further includes a sealing element 140, which is disposed on the baffle 130 and located between the housing 110 and the baffle 130. The sealing element 140 is configured to seal the gap between the housing 110 and the baffle 130 when the baffle 130 is in the closed position (i.e., the baffle 130 abuts against an end of the housing 110), thereby forming an airtight joint between the housing 110 and the baffle 130 and preventing gas from entering the storage chamber 112 through the joint between the housing 110 and the baffle 130.

[0072] In some embodiments, the sealing element 140 may also be disposed at the front end of the housing 110 , for example, the sealing element 140 is connected to the front end wall of the housing 110 .

[0073] In some embodiments, the sealing element 140 is annular. For example, the sealing element 140 is disposed on a side of the baffle 130 close to the housing 110 and extends along the circumference of the baffle 130. Alternatively, the sealing element 140 is disposed on the front end surface of the housing 110 and extends along the front end surface of the housing 110.

[0074] The sealing element 140 is annular and surrounds the storage container 120 , so that when the baffle 130 is closed and matched with the housing 110 , the sealing element 140 surrounds the storage opening 111 for sealing.

[0075] In some embodiments, the sealing element 140 has a deformable length along the moving direction of the storage container 120 being pushed into or pulled out of the shell 110. The distance that the sealing element 140 travels from its natural state to being compressed to the limit state is the deformable distance L0. It should be noted that when the sealing element 140 is compressed by the deformable distance L0, the sealing element 140 is difficult to be further compressed. When the baffle 130 is closed, the sealing element 140 is compressed under the joint extrusion of the baffle 130 and the front end wall of the shell 110, and the deformation length of the compressed sealing element 140 is no greater than the deformable distance L0. When the baffle 130 is opened, the baffle 130 is separated from the shell 110, the pressure applied to the sealing element 140 is removed, and the sealing element 140 returns to its natural state.

[0076] In some embodiments, the sealing element 140 is a compressible seal, for example, a rubber seal or an airbag seal.

[0077] In some embodiments, as shown in Figures 5 and 6, the sealing element 140 includes a first connecting strip 141, a first matching portion 142, a second connecting strip 143, and a third sealing portion 144. The baffle 130 includes a first connecting portion 134. The first connecting portion 134 is arranged on a side of the baffle 130 close to the shell 110 and is recessed in a direction away from the shell 110. For example, the first connecting portion 134 is in the shape of a groove. The first connecting portion 134 is arranged around the storage container 120. The first connecting strip 141 is installed in the first connecting portion 134. The first connecting strip 141 is elastic and slightly larger than the first connecting portion 134. In this way, when the first connecting strip 141 is installed in the first connecting portion 134, the inner wall of the first connecting portion 134 squeezes the first connecting strip 141, thereby sealingly connecting the first connecting strip 141 to the first connecting portion 134.

[0078] The first mating portion 142 is located on a side of the first connecting strip 141 close to the housing 110. The third sealing portion 144 is provided on a side of the first mating portion 142 close to the housing 110. The housing 110 further includes a first sealing portion 114. The first sealing portion 114 is provided at a front end portion of the housing 110. Thus, when the baffle 130 is in a closed position (i.e., the baffle 130 blocks the storage port 111), the first sealing portion 114 on the housing 110 is embedded in the third sealing portion 144, and the third sealing portion 144 is sealed and matched with the first sealing portion 114, thereby improving the sealing effect of the connection between the sealing element 140 and the housing 110.

[0079] For example, the third sealing portion 144 is a sealing groove.

[0080] In some embodiments, a recessed strip is formed on the wall surface of the first sealing portion 114 opposite to the baffle 130 to increase the deformation space of the first sealing portion 114 .

[0081] The second connecting strip 143 is located on a side of the first matching portion 142 close to the housing 110 , and the second connecting strip 143 is located on a side of the third sealing portion 144 close to the storage container 120 . That is, the third sealing portion 144 is disposed around the second connecting strip 143 .

[0082] The second connecting strip 143 includes a second connecting portion 1431 and a hook portion 1432. The second connecting portion 1431 is connected to the first matching portion 142 and extends toward a side away from the first connecting strip 141. The hook portion 1432 is connected to the second connecting portion 1431 and extends from an end of the second connecting portion 1431 away from the first connecting strip 141 to a side close to the third sealing portion 144. The shell 110 also includes a snap-fit ​​portion 115. The snap-fit ​​portion 115 is arranged on the inner wall surface of the storage cavity 112 and is close to the storage port 111. The snap-fit ​​portion 115 corresponds to the hook portion 1432. When the baffle 130 is closed, the second connecting portion 1431 extends into the storage cavity 112 and is located on the inner side of the storage cavity 112, and the hook portion 1432 is matched and snapped with the snap-fit ​​portion 115.

[0083] As configured above, there are multiple matching structures between the sealing element 140 and the shell 110, and the multiple matching structures are at different positions along the height direction of the refrigerator 1. In this way, the air outside the storage cavity 112 needs to pass through multiple matching structures at different height positions in the process of entering the storage cavity 112. The path is long and has many bends and turns, thereby reducing the amount of air entering the storage cavity 112 and extending the time the vacuum state in the storage cavity 112 is maintained.

[0084] In some embodiments, as shown in Figures 3 and 4, the refrigerator 1 further includes a ventilation device 300. The ventilation device 300 is provided on the housing 110 and is configured to control the disconnection or connection between the storage cavity 112 and the external environment of the storage device 100. When the exhaust device 200 is activated, the ventilation device 300 is in a closed state, and the storage cavity 112 is disconnected from the external environment of the storage device 100. When the storage device 100 needs to be opened, the ventilation device 300 is in an open state, and the storage cavity 112 is connected to the external environment of the storage device 100. In this way, external air can enter the storage device 100, so that the difference between the atmospheric pressure of the external environment and the pressure in the storage cavity 112 is reduced, thereby reducing the resistance when the user pulls the drawer assembly 101 out of the storage cavity 112, making it easier for the user to operate.

[0085] In some embodiments, the ventilation device 300 includes an electronic ventilation valve. For example, when the ventilation device 300 is powered off, the storage chamber 112 is isolated from the external environment, and the storage chamber 112 maintains a vacuum state. When the ventilation device 300 is powered on, the ventilation device 300 generates an electromagnetic force to overcome the elastic force of the spring inside the ventilation device 300, thereby connecting the interior of the storage device 100 with the outside.

[0086] In some embodiments, a vibration damping member is provided between the ventilation device 300 and the housing 110 to reduce vibration and noise caused by the operation of the ventilation device 300 .

[0087] In some embodiments, the housing 110 further includes ventilation holes, which are arranged in the sidewalls of the housing 110 along the width direction of the housing 110. When the baffle 130 is in the closed position, the ventilation device 300 opens the ventilation holes to connect the storage cavity 112 with the outside world, allowing outside air to enter the storage cavity 112 through the ventilation holes, balancing the internal and external air pressures, thereby facilitating the user to pull the drawer assembly 101 out of the housing 110.

[0088] FIG7 is a structural diagram of another storage device of a refrigerator according to some embodiments; FIG8 is a structural diagram of a door of a refrigerator according to some embodiments.

[0089] In some embodiments, as shown in Figures 7 and 8 , the vent device 300 is a mechanical button-type vent device, including a mechanical button. Thus, manually pressing the mechanical button opens the vent hole to equalize the pressure difference between the storage chamber 112 and the outside world. In this case, the vent hole can be provided in the baffle 130, and the vent device 300 can be provided on the baffle 130, corresponding to the position of the vent hole.

[0090] In some embodiments, as shown in FIG8 , a ventilation device 300 includes a pressing assembly 310, a conversion assembly 320, and a sealing assembly 330 (see FIG13 ). The conversion assembly 320 is connected to the pressing assembly 310, and the sealing assembly 330 is fixedly connected to the conversion assembly 320. The pressing assembly 310 is configured to perform reciprocating linear motion along a first direction S1 and a second direction S2, thereby driving the conversion assembly 320 to move.

[0091] The conversion component 320 is configured to drive the sealing component 330 to move in a curve when the pressing component 310 moves along the first direction S1 or the second direction S2, driven by the pressing component 310, so as to separate the sealing component 330 from the vent hole, thereby opening the vent hole, or to drive the sealing component 330 to move in a curve so as to block the vent hole.

[0092] It should be noted that the curvilinear motion here includes not only circular motion around a single axis, but also non-circular motion around a variable rotation axis.

[0093] For example, the conversion assembly 320 is further configured such that, when the pressing assembly 310 moves linearly along the second direction S2, the conversion assembly 320 drives the sealing assembly 330 to rotate in a direction away from the vent hole. For example, the sealing assembly 330 rotates in a direction away from the front wall surface and the bottom wall surface of the baffle 130.

[0094] The conversion assembly 320 is further configured such that when the pressing assembly 310 linearly moves in the first direction S1, the conversion assembly 320 drives the sealing assembly 330 to rotate toward the vent hole. For example, the sealing assembly 330 rotates toward the front wall surface and the bottom wall surface of the baffle 130.

[0095] It is understandable that, as configured above, the linear motion of the pressing component 310 is converted into the rotational motion of the sealing component 330 so that the sealing component 330 opens or blocks the vent hole, which is convenient for user operation and conforms to the user's operating habits.

[0096] In some embodiments, as shown in FIG8 , the ventilation device 300 further includes a reset assembly 340. The reset assembly 340 is connected to the conversion assembly 320. The reset assembly 340 is configured to elastically deform and store elastic potential energy when an external force acts on the pressing assembly 310, causing the pressing assembly 310 to move in the second direction S2. The reset assembly 340 is also configured to release the stored elastic potential energy when the external force acting on the pressing assembly 310, causing the pressing assembly 310 to move in the second direction S2, is removed, causing the pressing assembly 310 and the conversion assembly 320 to return to their initial positions. When the pressing assembly 310 and the conversion assembly 320 are in their initial positions, the sealing assembly 330 blocks the vent hole.

[0097] In some embodiments, as shown in Figures 7 and 8, the baffle 130 includes a mounting plate 131 and a panel 132. The panel 132 is located on a side of the mounting plate 131 away from the housing 110. The mounting plate 131 includes a recessed portion 1311, which opens toward the panel 132 and is recessed in a direction away from the panel 132. The ventilator 300 is mounted in the recessed portion 1311. The panel 132 includes a through hole 1321, which corresponds to the position of the ventilator 300 and is configured to allow the pressing assembly 310 of the ventilator 300 to pass through and extend to the side of the panel 132 away from the mounting plate 131, thereby facilitating the user's pressing operation.

[0098] In some embodiments, the baffle 130 further includes a fixing member 133. The fixing member 133 is disposed within the recessed portion 1311 and is configured to secure the ventilator 300. For example, the fixing member 133 is disposed on the bottom wall of the recessed portion 1311 and is secured to the inner wall of the recessed portion 1311 by snapping. A plurality of vent holes are located on the bottom wall of the recessed portion 1311 and on at least one side of the fixing member 133.

[0099] FIG9 is an exploded view of a ventilation device of a refrigerator according to some embodiments; FIG10 is a structural diagram of a fixing member of a refrigerator according to some embodiments.

[0100] In some embodiments, as shown in Figures 7 to 9, the pressing assembly 310 includes a button 311. The resetting assembly 340 includes a spring 343. The spring 343 is positioned on the side of the button 311 near the mounting plate 131 and abuts against the button 311. When the user presses the button 311, the button 311 compresses the spring 343. When the external force is removed, the spring 343 returns to its original position, extending its length and driving the button 311 to its initial position.

[0101] In some embodiments, as shown in Figures 9 and 10, the fixing member 133 includes a mounting post 1331 and a third mounting hole 1332 (i.e., a mounting hole). The mounting post 1331 corresponds to the position of the spring 343, and the third mounting hole 1332 is disposed in the mounting post 1331. The third mounting hole 1332 is open toward the panel 132. The spring 343 is disposed in the third mounting hole 1332.

[0102] In some embodiments, as shown in Figures 8 to 10, the pressing assembly 310 includes two springs 343. The fixing member 133 includes two third mounting holes 1332 and two mounting posts 1331. The two springs 343 are respectively disposed in the two third mounting holes 1332 and abut against a side wall of the button 311 near the mounting plate 131 to support the opposite ends of the button 311, thereby improving the stability of the button 311 when pressed.

[0103] In some embodiments, as shown in FIG9 , the button 311 includes a pressing front wall 3111 and a pressing side wall 3112 extending circumferentially of the pressing front wall 3111. One end of a spring 343 is mounted within the third mounting hole 1332, and the other end engages and abuts against the pressing front wall 3111. A certain distance exists between the pressing front wall 3111 and the end surface of the mounting post 1331 proximal to the pressing front wall 3111. This allows an external force to act on the button 311, causing the spring 343 to compress. The pressing side wall 3112 passes through the through hole 1321 and cooperates with the through hole 1321 to guide the movement of the button 311.

[0104] In some embodiments, the button 311 further includes a stopper plate. The stopper plate is disposed at an end of the pressing side wall 3112 away from the pressing front wall 3111 and outside the pressing front wall 3111. The stopper plate abuts against a side of the panel 132 near the mounting plate 131 to prevent the button 311 from disengaging from the passage hole 1321 under the action of the spring 343.

[0105] FIG. 11 is a structural diagram of buttons of a refrigerator according to some embodiments.

[0106] In some embodiments, as shown in Figures 8 and 11, the button 311 further includes a first guide plate 3113 (i.e., guide plate) and a second guide plate 3114 (i.e., guide plate). The first guide plate 3113 and the second guide plate 3114 are disposed on a side of the pressing front wall 3111 near the mounting post 1331. The first guide plate 3113 and the second guide plate 3114 are spaced apart and located between the two springs 343.

[0107] The fixing member 133 also includes a first guide portion 1333 (i.e., guide portion) and a second guide portion 1334 (i.e., guide portion). The first guide portion 1333 and the second guide portion 1334 are spaced apart and disposed between the two mounting posts 1331. The first guide plate 3113 cooperates with the first guide portion 1333, and the second guide plate 3114 cooperates with the second guide portion 1334. The first guide plate 3113 moves linearly within the first guide portion 1333, and the second guide plate 3114 moves linearly within the second guide portion 1334.

[0108] For example, the first guide portion 1333 and the second guide portion 1334 are strip-shaped grooves, so that the first guide plate 3113 and the second guide plate 3114 can move along a straight line in the first guide portion 1333 and the second guide portion 1334 respectively.

[0109] FIG12 is a perspective view of a first adapter of a refrigerator according to some embodiments; FIG13 is an exploded view of a second adapter and a sealing plug of a refrigerator according to some embodiments.

[0110] In some embodiments, as shown in Figures 8, 12, and 13, the conversion assembly 320 includes a first adapter 350 and a second adapter 360. The first adapter 350 is connected to the pressing assembly 310. The sealing assembly 330 includes a sealing plug 331, which is connected to the second adapter 360. When the pressing assembly 310 moves linearly, it drives the first adapter 350 to rotate, and the first adapter 350 drives the sealing plug 331 to move through the second adapter 360.

[0111] 12 , the first adapter 350 includes a first connecting plate 351, a second connecting plate 352, and a third connecting plate 353. The first end of the first connecting plate 351 is connected to the first end of the second connecting plate 352 and the first end of the third connecting plate 353, respectively.

[0112] The first adapter 350 further includes a first protrusion 354 and a second protrusion 355. The first protrusion 354 and the second protrusion 355 are coaxially disposed at the second end of the first connecting plate 351 and are located on opposite sides of the first connecting plate 351 along the thickness direction of the first connecting plate 351.

[0113] In some embodiments, as shown in FIG11 , the button 311 further includes a first mating hole 3115 and a second mating hole 3116. The first mating hole 3115 is disposed on the first guide plate 3113 and extends through the first guide plate 3113. The second mating hole 3116 is disposed on the second guide plate 3114 and extends through the second guide plate 3114. The first protrusion 354 is disposed within the first mating hole 3115, and the second protrusion 355 is disposed within the second mating hole 3116.

[0114] The first mating hole 3115 and the second mating hole 3116 are each configured as an elongated hole, and the elongated hole extends along the height direction of the refrigerator 1. In this way, the first protrusion 354 can move along the length direction of the first mating hole 3115, and the second protrusion 355 can move along the length direction of the elongated second mating hole 3116.

[0115] It can be understood that the length direction of the first mating hole 3115 and the second mating hole 3116 is perpendicular to the moving direction of the button 311, so that when the first guide plate 3113 and the second guide plate 3114 move, they can drive the first protrusion 354 and the second protrusion 355 to move in the same direction, and make the first protrusion 354 move a certain distance along the length direction of the first mating hole 3115, and the second protrusion 355 move a certain distance along the length direction of the second mating hole 3116.

[0116] 10 , the fixing member 133 further includes a third guide portion 1335 , which is open toward the panel 132 . The third guide portion 1335 is located between the first guide portion 1333 and the second guide portion 1334 , and the first connecting plate 351 is located within the third guide portion 1335 .

[0117] It should be noted that the first guide portion 1333 can limit the movement direction of the first guide plate 3113, the second guide portion 1334 can limit the movement direction of the second guide plate 3114, the third guide portion 1335 can limit the movement direction of the first connecting plate 351, and the mounting post 1331 can limit the compression or recovery direction of the spring 343. Under the constraints of these components, when an external force acts on the button 311, the button 311 acts on the spring 343, compressing it, causing the first guide plate 3113 and the second guide plate 3114 to move with the button 311. The first and second guide plates 3113 and 3114, via the first and second protrusions 354 and 355, drive the first connecting plate 351 to move within the third guide portion 1335.

[0118] 12 , the first adapter 350 further includes a third protrusion 356 and a fourth protrusion 357. The third protrusion 356 and the fourth protrusion 357 are coaxially disposed at the second end of the second connecting plate 352 and are disposed on opposite sides of the second connecting plate 352 along the thickness direction of the second connecting plate 352.

[0119] In some embodiments, as shown in FIG10 , the fixing member 133 further includes a first fixing portion 1336 and a second fixing portion 1337. The first fixing portion 1336 and the second fixing portion 1337 are spaced apart along the width direction of the housing 110. The gap between the first fixing portion 1336 and the second fixing portion 1337 is connected to the second guide portion 1334.

[0120] The second end of the second connecting plate 352 is positioned between the first fixing portion 1336 and the second fixing portion 1337. The third protrusion 356 is connected to the first fixing portion 1336, and the fourth protrusion 357 is connected to the second fixing portion 1337, so that the second connecting plate 352 can rotate relative to the first fixing portion 1336 and the second fixing portion 1337. For example, the second connecting plate 352 can rotate relative to the first fixing portion 1336 or the second fixing portion 1337 about the central axis of the third protrusion 356 and the fourth protrusion 357.

[0121] In some embodiments, in the plane where the first connecting plate 351 is located, the angle between the first connecting plate 351 and the third connecting plate 353 is a straight angle, and the angle between the second connecting plate 352 and the third connecting plate 353 is an acute angle.

[0122] In some embodiments, as shown in Figures 8 and 13, the second adapter 360 includes a conversion plate 361. The conversion plate 361 includes a first side adjacent to the fixing member 133 and a second side opposite the first side. The first side and the second side are perpendicular to the plane where the second connecting plate 352 is located.

[0123] The conversion plate 361 further includes a first limiting hole 3611 and a second limiting hole 3612. The first limiting hole 3611 and the second limiting hole 3612 are oppositely arranged at two ends of the first side.

[0124] The fixing member 133 also includes a first stopper 1338 and a second stopper 1339. The first stopper 1338 and the second stopper 1339 are disposed opposite each other on the inner wall of the fixing member 133 and are coaxial. The first stopper 1338 is mounted within the first stopper hole 3611 and is rotatable relative to the first stopper hole 3611. The second stopper 1339 is mounted within the second stopper hole 722 and is rotatable relative to the second stopper hole 3612. This allows the conversion plate 361 to rotate relative to the fixing member 133.

[0125] For example, the first limiting portion 1338 and the second limiting portion 1339 are substantially cylindrical.

[0126] In some embodiments, as shown in FIG13 , the second adapter 360 further includes a fifth protrusion 362 and a sixth protrusion 363. The fifth protrusion 362 and the sixth protrusion 363 are located at opposite ends of the first side. A first limiting hole 3611 is provided in the fifth protrusion 362 and extends through the fifth protrusion 362 along its length. A second limiting hole 3612 is provided in the sixth protrusion 363 and extends through the sixth protrusion 363 along its length.

[0127] In some embodiments, as shown in FIG. 8 , the reset assembly 340 includes a first reset torsion spring 341 and a second reset torsion spring 342 .

[0128] The first return torsion spring 341 is sleeved on the outer side of the fifth protrusion 362. One torsion arm of the first return torsion spring 341 is in contact with the fixing member 133, and the other torsion arm of the first return torsion spring 341 is in contact with the conversion plate 361.

[0129] The second return torsion spring 342 is sleeved on the outer side of the sixth protrusion 363. One torsion arm of the second return torsion spring 342 is in contact with the fixing member 133, and the other torsion arm of the second return torsion spring 342 is in contact with the conversion plate 361.

[0130] In this way, when the ventilation device 300 blocks the ventilation hole, under the combined action of the elastic forces of the first return torsion spring 341 and the second return torsion spring 342, the sealing plug 331 has sufficient sealing force on the ventilation hole, thereby improving the reliability of the ventilation device 300 in sealing the ventilation hole.

[0131] In some embodiments, as shown in Figures 12 and 13, the conversion plate 361 further includes a first through hole 3613 and a second through hole 3614. The first through hole 3613 and the second through hole 3614 are disposed at opposite ends of the second side of the conversion plate 361. The first adapter 350 further includes a third through hole 358 disposed at the second end of the third connecting plate 353.

[0132] In some embodiments, as shown in FIG8 , the conversion assembly 320 further includes a connecting post 321. The connecting post 321 is provided with a first through hole 3613, a second through hole 3614, and a third through hole 358 to rotatably connect the third connecting plate 353 to the conversion plate 361. Thus, the conversion plate 361 can rotate about the connecting post 321, driven by the third connecting plate 353.

[0133] In some embodiments, as shown in FIG8 , the second adapter 360 further includes two blocking portions 322 . The two blocking portions 322 are disposed at both ends of the connecting post 321 . At least one of the two blocking portions 322 is detachably connected to the connecting post 321 . Thus, after the connecting post 321 passes through the first through hole 3613 , the third through hole 358 , and the second through hole 3614 , the two blocking portions 322 can secure both ends of the connecting post 321 , thereby preventing the connecting post 321 from detaching from the first through hole 3613 , the third through hole 358 , or the second through hole 3614 , thereby improving the connection strength and stability of the connecting post 321 , the third connecting plate 353 , and the conversion plate 361 .

[0134] FIG. 14 is a structural diagram of a second adapter and a sealing plug of a refrigerator according to some embodiments.

[0135] In some embodiments, as shown in Figures 13 and 14, second adapter 360 further includes a mounting seat 364. Mounting seat 364 is disposed on a second side of conversion plate 361 and is configured to secure sealing plug 331. Thus, when second adapter 360 is driven by first adapter 350 to move, it drives sealing plug 331 to move, thereby sealing plug 331 and sealing the vent hole.

[0136] In some embodiments, as shown in FIG. 13 and FIG. 14 , the mounting base 364 includes a first connecting plate 3641 , a second connecting plate 3642 , a third connecting plate 3643 , and a fourth connecting plate 3644 .

[0137] When the sealing plug 331 blocks the vent hole, the first connecting plate 3641 is perpendicular to the baffle 130 and close to the conversion plate 361. The second connecting plate 3642 is located on a side of the first connecting plate 3641 away from the conversion plate 361 and is tilted relative to the first connecting plate 3641.

[0138] The third connecting plate 3643 is connected to the first connecting plate 3641 and the second connecting plate 3642, respectively, and is located between the first connecting plate 3641 and the second connecting plate 3642. The fourth connecting plate 3644 is connected to the first connecting plate 3641 and the second connecting plate 3642, respectively, and is located between the first connecting plate 3641 and the second connecting plate 3642. The fourth connecting plate 3644 is located on a side of the third connecting plate 3643 that is away from the second side of the conversion plate 361 (i.e., away from the panel 132).

[0139] For example, the third connecting plate 3643 and the fourth connecting plate 3644 are both perpendicular to the first connecting plate 3641 .

[0140] 13 , the mounting base 364 further includes a snap-fit ​​hole 3645 . The snap-fit ​​hole 3645 is disposed in the fourth connecting plate 3644 and passes through the fourth connecting plate 3644 .

[0141] As shown in Figures 13 and 14, the sealing assembly 330 also includes a snap-in recess 332. The snap-in recess 332 is provided at a central position of the sealing plug 331 and extends along the circumference of the sealing plug 331. The snap-in recess 332 is recessed toward the radial inner side of the sealing plug 331. One axial end of the sealing plug 331 passes through the snap-in hole 3645 and is installed between the third connecting plate 3643 and the fourth connecting plate 3644, and the fourth connecting plate 3644 is snap-fitted to the snap-in recess 332. The other axial end of the sealing plug 331 cooperates with the vent hole. In this way, when the ventilation device 300 is in the closed state, the sealing plug 331 blocks the vent hole.

[0142] Figure 15 is a cross-sectional view of a refrigerator when the door is closed (the button is in the initial state) according to some embodiments; Figure 16 is a cross-sectional view of a refrigerator when the door is closed (the button is in the first pressure state) according to some embodiments; Figure 17 is a cross-sectional view of a refrigerator when the door is closed (the button is in the second pressure state) according to some embodiments; Figure 18 is a cross-sectional view of a refrigerator when the door is closed (the button is in the third pressure state) according to some embodiments.

[0143] 15 to 18 , the process of opening and closing the vent hole of the vent device 300 will be described in detail.

[0144] As shown in FIG15 , when the button 311 is not acted upon by an external force, the ventilation device 300 is in an initial state (ie, the button 311 is in an initial state), the spring 343 is in a natural state, and the sealing plug 331 blocks the ventilation hole.

[0145] As shown in Figures 16 to 18, during the process of the ventilation device 300 opening the vent hole, the button 311 is pressed and moves from the first compressed state (corresponding to Figure 15) to the second compressed state (corresponding to Figure 16), and then to the third compressed state (corresponding to Figure 17).

[0146] The process of opening the vent hole of the vent device 300 includes the following steps:

[0147] The button 311 applies a force to the spring 343 to contract the spring 343 , and the button 311 drives the first guide plate 3113 and the second guide plate 3114 to move in the same direction.

[0148] The first guide plate 3113 and the second guide plate 3114 respectively drive the first protrusion 354 and the second protrusion 355 to move, thereby driving the first connecting plate 351 to move. The second connecting plate 352 and the third connecting plate 353 move along with the first connecting plate 351.

[0149] Driven by the first connecting plate 351, the second connecting plate 352 rotates around the central axis of the third protrusion 356 and the fourth protrusion 357. At the same time, the first protrusion 354 moves along the length direction of the first matching hole 3115, and the second protrusion 355 moves along the length direction of the second matching hole 3116.

[0150] Driven by the first connecting plate 351 and the second connecting plate 352 , the third connecting plate 353 rotates around the central axis of the third protruding portion 356 and the fourth protruding portion 357 .

[0151] The third connecting plate 353 drives the conversion plate 361 to rotate around the connecting column 321 through the connecting column 321, and rotates around the central axis of the third protrusion 356 and the fourth protrusion 357, thereby compressing the first return torsion spring 341 and the second return torsion spring 342, causing the first return torsion spring 341 and the second return torsion spring 342 to store elastic potential energy.

[0152] The conversion plate 361 drives the sealing plug 331 away from the vent hole through the mounting seat 364, so that the vent hole is opened, and the outside air can enter the storage cavity 112 through the vent hole.

[0153] The process of sealing the vent hole by the vent device 300 includes the following steps:

[0154] When the external force acting on the button 311 is removed, the first return torsion spring 341, the second return torsion spring 342 and the spring 343 release their elastic potential energy, so that the button 311, the first adapter 350 and the second adapter 360 return to their original state, and the sealing plug 331 blocks the vent hole again and presses the vent hole under the action of the first return torsion spring 341 and the second return torsion spring 342 to ensure the effectiveness of the seal.

[0155] It is understandable that under the combined action of the first return torsion spring 341 , the second return torsion spring 342 and the elastic force of the spring 343 , the sealing plug 331 has sufficient sealing force on the vent hole, thereby improving the reliability of the ventilation device 300 in sealing the vent hole.

[0156] In some embodiments, as shown in FIG4 , the storage device 100 further includes a rail assembly 400. The rail assembly 400 is fixedly connected to the storage container 120 and the housing 110, respectively. The rail assembly 400 is retractable to allow the drawer assembly 101 to move relative to the housing 110. For example, the drawer assembly 101 can be withdrawn from or pushed into the housing 110 via the rail assembly 400, thereby facilitating smoother movement of the drawer assembly 101.

[0157] FIG. 19 is a structural diagram of a locking assembly and a guide rail assembly of a refrigerator according to some embodiments.

[0158] 19 , the guide rail assembly 400 further includes a locking assembly 401 . The locking assembly 401 is configured to lock the baffle 130 and the housing 110 when the baffle 130 blocks the storage port 111 .

[0159] For example, when the baffle 130 blocks the storage port 111 and the sealing element 140 is squeezed, the locking assembly 401 can lock the baffle 130 in the pre-locking position and allow the baffle 130 to continue to move a certain distance along the second direction S2 under the action of the force.

[0160] It can be understood that when the locking assembly 401 locks the baffle 130 in the pre-locking position, the sealing element 140 is in a compressed state under the action of the baffle 130 and the shell 110, thereby ensuring that the baffle 130 and the sealing element 140 have a certain sealing performance on the storage port 111.

[0161] When the locking assembly 401 is in the pre-locking position, the length by which the sealing element 140 is compressed is recorded as the pre-locking compression distance L1. The pre-locking compression distance L1 is less than the deformable distance L0. Thus, when the baffle 130 continues to move in the second direction S2 from the pre-locking position, the sealing element 140 can be further compressed, thereby facilitating improved sealing between the baffle 130 and the housing 110.

[0162] In some embodiments, when the locking assembly 401 is in the pre-locked position, the air extraction device 200 is activated, and the air extraction rate of the air extraction device 200 is much greater than the rate at which external air enters the storage chamber 112. In this situation, the air pressure within the storage chamber 112 decreases, and the external atmospheric pressure is greater than the air pressure within the storage chamber 112. Due to the pressure difference between the external atmospheric pressure and the air pressure within the storage chamber 112, the baffle 130 causes the storage container 120 to slightly displace in the second direction S2 via the guide rail assembly 400, further compressing the sealing element 140.

[0163] When the vacuuming is completed, the compressed length of the sealing element 140 is the vacuum compression distance L2, which is greater than the pre-locking compression distance L1, thereby improving the sealing performance of the baffle 130 and the shell 110. In this way, the sealing performance of the storage cavity 112 can also be improved, and the shelf life of the food in the storage cavity 112 can be effectively extended.

[0164] In some embodiments, the vacuum compression distance L2 is less than or equal to the deformable distance L0 to ensure that the sealing element 140 is continuously compressed when the baffle 130 moves from the pre-locking position to the vacuum locking position, thereby facilitating the sealing between the baffle 130 and the housing 110.

[0165] In some embodiments, the ratio of the pre-locking compression distance L1 to the deformable distance L0 is any value between 0.05 and 0.1. That is, L1:L2∈[0.05, 0.1]. The pre-locking compression distance L1 is any value between 0 and 1 mm, that is, L1∈(0, 1], in mm.

[0166] When the baffle 130 is closed, the baffle 130 and the housing 110 press the sealing element 140 and reach the pre-locked position. In this way, when the user pushes the drawer assembly 101 to continue moving in the second direction S2, the baffle 130 can be moved to the locked position without increasing the force, so that the storage cavity 112 reaches the pre-sealed state, providing initial sealing conditions for vacuuming.

[0167] In some embodiments, as shown in FIG19 , the guide rail assembly 400 includes an outer rail 430 and an inner rail 410. The outer rail 430 is fixedly connected to the inner wall of the housing 110, and the inner rail 410 is fixedly connected to the storage container 120. The outer rail 430 and the inner rail 410 are movably connected. For example, the outer rail 430 and the inner rail 410 are slidably connected.

[0168] When the drawer assembly 101 is withdrawn, the baffle 130 is moved in the first direction S1 by the force applied thereto, driving the storage container 120 in the first direction S1. The storage container 120 then drives the inner rail 410 in the first direction S1, causing the inner rail 410 to move relative to the outer rail 430 in the first direction S1, away from the housing rear wall 113. This allows the storage container 120 to be withdrawn from the storage cavity 112, making it easier for the user to retrieve and place items.

[0169] As the drawer assembly 101 is pushed into the housing 110, the baffle 130, under the action of force, moves in the second direction S2, driving the storage container 120 in the second direction S2. The storage container 120 drives the inner rail 410 in the second direction S2. The inner rail 410 moves relative to the outer rail 430 in the second direction S2 toward the housing rear wall 113. The storage container 120 is pushed into the storage cavity 112, and the baffle 130 blocks the storage opening 111. The locking assembly 401 locks the baffle 130 in the pre-locked position, compressing the sealing element 140 by the pre-locking compression distance L1, sealing the baffle 130 with the housing 110.

[0170] In this situation, the air extraction device 200 is activated, and its extraction rate is much greater than the rate at which external air enters the storage chamber 112. As a result, the air pressure in the storage chamber 112 decreases, and the external atmospheric pressure becomes greater than the air pressure in the storage chamber 112. Due to the pressure difference between the external atmospheric pressure and the air pressure in the storage chamber 112, the baffle 130 causes the storage container 120 to slightly displace in the first direction S1 via the guide rail assembly 400, further tightening the sealing element 140.

[0171] After the vacuuming is completed, the compressed length of the sealing element 140 is the vacuum compression distance L2, which is greater than the pre-locking compression distance L1, thereby facilitating improved sealing between the baffle 130 and the housing 110.

[0172] In some embodiments, as shown in FIG19 , guide rail assembly 400 further includes a middle rail 420. Outer rail 430 is movably connected to inner rail 410 via middle rail 420. For example, middle rail 420 is slidably connected to inner rail 410, and outer rail 430 is slidably connected to middle rail 420. This effectively extends the range of extension and retraction of guide rail assembly 400.

[0173] When the drawer assembly 101 is pulled out, the baffle 130 moves along the first direction S1 under the action of force, and drives the storage container 120 to move along the first direction S1. The storage container 120 drives the inner rail 410 to move along the first direction S1. The inner rail 410 moves a certain distance relative to the middle rail 420 along the first direction S1. The middle rail 420 moves a certain distance relative to the outer rail 430 along the first direction S1. The storage container 120 is pulled out of the storage cavity 112, making it convenient for users to take and put items.

[0174] It can be understood that, during the process of the drawer assembly 101 being pulled out, the inner rail 410 moves a certain distance relative to the middle rail 420 along the first direction S1, and the middle rail 420 moves a certain distance relative to the outer rail 430 along the first direction S1, thereby effectively extending the extension distance of the guide rail assembly 400, so that the storage container 120 can be completely pulled out of the storage cavity 112, making it convenient for users to take and place items.

[0175] As the drawer assembly 101 is pushed into the housing 110, the baffle 130 is forced to move in the second direction S2, driving the storage container 120 in the second direction S2. The storage container 120 drives the inner rail 410 in the second direction S2, causing the inner rail 410 to move a predetermined distance relative to the middle rail 420 in the second direction S2. The middle rail 420 moves a predetermined distance relative to the outer rail 430 in the second direction S2, pushing the storage container 120 into the storage cavity 112. The baffle 130 blocks the storage opening 111, and the locking assembly 401 locks the baffle 130 in the pre-locked position. The sealing element 140 is compressed by the pre-locking compression distance L1, sealing the baffle 130 with the housing 110.

[0176] In some embodiments, as shown in Figure 19, the locking assembly 401 is configured as a push-to-open locking assembly. The push-to-open locking assembly is configured to switch between a locked state and an unlocked state when pressed.

[0177] In some embodiments, after the pressure inside and outside the storage chamber 112 is balanced by the ventilation device, the pressure difference between the pressure inside the storage chamber 112 and the atmospheric pressure decreases. In this case, by pushing the baffle 130, the push-to-open locking assembly is pressed, the push-to-open locking assembly is unlocked and popped open, and the baffle 130 automatically pops open under the push force of the push-to-open locking assembly, thereby automatically opening the drawer assembly 101.

[0178] In some embodiments, the push-to-lock assembly has an unlocking distance J0. This unlocking distance J0 is the maximum distance the locking assembly can be pressed and moved. The deformable distance L0 of the sealing element 140 is greater than the unlocking distance J0 of the push-to-lock assembly. When the baffle 130 is closed, the push-to-lock assembly compresses the baffle 130 and the housing 110 against the sealing element 140, forcing the baffle 130 into a pre-locked position, forming a pre-seal.

[0179] At this point, the sealing element 140 is compressed to the pre-locking compression distance L1. After the vacuum pump 210 evacuates the storage device 100, a negative pressure (e.g., less than 0.9 atm) forms. Under these conditions, the pressure differential between the inside and outside of the storage chamber 112 acts on the baffle 130, squeezing the sealing element 140 to the vacuum compression distance L2. The baffle 130 acts on the push-to-open locking assembly, triggering its opening.

[0180] When the pressure differential between the inside and outside of the storage device 100 is eliminated, the push-to-open locking assembly unlocks. For example, the difference between the vacuum compression distance L2 and the pre-lock compression distance L1 is greater than or equal to the unlocking distance J0 of the push-to-open locking assembly, i.e., L2 - L1 ≥ J0. Thus, when the storage device 100 is in a vacuum-sealed state, the unlocking of the push-to-open locking assembly has been triggered. Thus, when the pressure differential between the inside and outside of the storage device 100 is eliminated, the push-to-open locking assembly unlocks, causing the drawer assembly 101 to automatically open.

[0181] In some embodiments, during the compression of the sealing element 140 from the pre-sealing position to the deformable distance L0, the distance compressed by the sealing element 140 is the difference between the deformable distance L0 and the pre-locking compression distance L1. Furthermore, the difference between the deformable distance L0 and the pre-locking compression distance L1 is greater than the unlocking distance J0 of the push-to-open locking assembly, i.e., L0-L1 ≥ J0. This ensures that the push-to-open locking assembly can be unlocked under the action of an external force. For example, the difference between the deformable distance L0 and the pre-locking compression distance L1 is any value between 2 mm and 3 mm, and J0 is any value between 1 mm and 2 mm.

[0182] In some embodiments, the push-to-open locking assembly remains in a self-locking state even after the pressure differential between the inside and outside of the storage device 100 is released. Specifically, the sealing element 140 is squeezed by the pressure differential between the inside and outside of the storage device 100 on the baffle 130, and its compression distance reaches the vacuum compression distance L2. At this point, the baffle 130 acts on the push-to-open locking assembly, but this is insufficient to trigger its release. At this point, the vacuum compression distance L2 is less than the deformable distance L0. L2 - L1 is less than J0, and L0 - L1 is greater than or equal to J0. This ensures that the push-to-open locking assembly can be unlocked under external force and remains locked even after the pressure differential between the inside and outside of the storage device 100 is released.

[0183] In some embodiments, the pressure inside the storage device 100 is P1 (e.g., any value between 0.7 atm and 0.9 atm), and the pressure outside the baffle 130 is P0 (e.g., 1 atm). The area of ​​the baffle 130 is S, and the force required to trigger the push-to-open locking assembly is F1, where F1 < (P0 - P1) * S. In this manner, when the ventilation device is opened, the drawer assembly 101 can automatically open.

[0184] Figure 20 is a structural diagram of another locking assembly and guide rail assembly (in an open state) of a refrigerator according to some embodiments; Figure 21 is a structural diagram of another locking assembly and guide rail assembly (in a closed state) of a refrigerator according to some embodiments.

[0185] In some embodiments, as shown in Figures 20 and 21, the locking assembly 401 is configured as a dual self-locking locking assembly. This dual self-locking locking assembly enables a dual locking function. During the closing process of the baffle 130, the inner rail 410 moves a first distance in the second direction S2, and the inner rail 410 and the outer rail 430 complete a first-level locking. After the first-level locking, the inner rail 410 continues to move a second distance in the second direction S2, and the inner rail 410 and the outer rail 430 complete a second-level locking. This enhances the self-locking effect of the self-locking assembly, prompting the baffle 130 to block the storage opening 111, and helps improve the stability and reliability of the drawer assembly 101.

[0186] In some embodiments, when the inner rail 410 and the outer rail 430 complete the first-stage locking, the baffle 130 is in the pre-locked position. When the inner rail 410 and the outer rail 430 complete the second-stage locking, the vacuum device activates, extracting air from the storage chamber 112 and placing the baffle 130 in a vacuum-locked state. In this state, the baffle 130 is subjected to the second-stage locking action and the pressure differential between the inside and outside, effectively ensuring the seal between the baffle 130 and the housing 110 and extending the pressure retention period of the storage chamber 112.

[0187] In some embodiments, a first locking portion is provided on the inner rail 410 and a second locking portion is provided on the outer rail 430. When the baffle 130 is closed, after the baffle 130 moves a first distance, the first locking portion cooperates with the second locking portion to complete the first level of locking.

[0188] Then, a certain external force is applied to the inner rail 410, or under the action of the inertial force of the inner rail 410, or under the action of the elastic tension triggered by the first-level locking action, the inner rail 410 continues to move a second distance along the second direction S2, and the inner rail 410 and the outer rail 430 complete the second-level locking.

[0189] In some embodiments, as shown in Figures 20 and 21, the second locking portion is provided on the first connecting member, and the first connecting member is rotatably connected to the outer rail 430. A torsion spring is provided between the first connecting member and the end of the outer rail 430 away from the storage port 111. When the first locking portion and the second locking portion cooperate to complete the first level of locking, the first locking portion on the inner rail 410 compresses the torsion spring through the first connecting member, causing the torsion spring to be compressed in the radial direction. When the first locking portion and the second locking portion complete the first level of locking, the torsion spring reaches the torsion spring critical value. Afterwards, the torsion spring begins to stretch, and drives the inner rail 410 to continue to move a second distance along the second direction S2 through the first connecting member, thereby completing the second level of locking.

[0190] It can be understood that the above arrangement can automatically complete the second level locking after the first level locking is completed by the first locking part and the second locking part, and can improve the reliability and stability of the locking component 401, which is conducive to extending the service life of the locking component 401.

[0191] FIG. 22 is a structural diagram of yet another locking assembly and guide rail assembly of a refrigerator according to some embodiments.

[0192] In some embodiments, as shown in Figure 22, the locking assembly 401 is configured as a snap-switch type locking assembly. When the snap-switch type locking assembly is locked, the baffle 130 reaches a pre-locked position. A first locking portion is provided on the inner rail 410, and a second locking portion is provided on the outer rail 430. When the baffle 130 is closed, the baffle 130 moves a first distance under the action of an external force, and the first locking portion and the second locking portion cooperate to complete the locking.

[0193] For example, the first locking portion includes a buckle, and the second locking portion includes a slot. When the buckle and the slot are engaged, the buckle undergoes elastic deformation and enters the slot, and then the buckle has at least a recovery portion to complete the locking with the slot.

[0194] In some embodiments, the storage device 100 further includes a pressure monitoring component. The pressure monitoring component is disposed in the storage chamber 112 and is configured to monitor the pressure state in the storage chamber 112 in real time. The pressure monitoring component is coupled to the controller.

[0195] When the air extraction device 200 is working, the pressure monitoring component monitors the pressure in the storage chamber 112. The controller is further configured to control the air extraction device 200 to stop working when the pressure in the storage chamber 112 reaches a first pressure value.

[0196] It is understood that when the storage device 100 stores food in a low-pressure environment, external gas will slowly enter the storage chamber 112, increasing the pressure in the storage chamber 112. The controller is further configured to control the air extraction device 200 to start when the pressure in the storage chamber 112 rises to a second pressure value, thereby reducing the pressure in the storage chamber 112.

[0197] It should be noted that the second pressure value is lower than the standard atmospheric pressure and higher than the first pressure value. As described above, the pressure in the storage chamber 112 can be kept lower than the standard atmospheric pressure, thereby extending the food preservation time.

[0198] 23 is a cross-sectional view of a refrigerator according to some embodiments.

[0199] In some embodiments, as shown in Figures 1, 2 and 23, the refrigerator 1 includes two doors 11 and a flip beam 14 that are arranged opposite to each other. The two doors 11 cooperate with each other to open or close the access opening 13.

[0200] A flip beam 14 is disposed at one end of one door 11, near the other door 11. A guide rail is provided on the inner top wall of the storage chamber 12, and the flip beam 14 is configured to slide with the guide rail to enable the flip beam 14 to be moved at different angles relative to the doors 11. Thus, when the two doors 11 are closed, the flip beam 14 can block the gap between the two doors 11 and the refrigerator body 10, effectively preventing cold air from escaping and improving the cooling effect of the refrigerator 1.

[0201] In some embodiments, as shown in Figures 2 and 23 , the flip beam 14 includes a flip axis M and a free end N. The flip axis M is the rotation axis of the flip beam 14. The free end N extends parallel to the flip axis M and rotates about the flip axis M. The flip beam 14 is located on the side of the baffle 130 away from the housing 110. When the door 11 is closed, the orthographic projection of the flip beam 14 on the plane of the access opening 13 at least partially overlaps with the orthographic projection of the baffle 130 on the plane of the access opening 13.

[0202] The direction parallel to the plane where the pick-up and release port 13 is located and perpendicular to the flip axis M is defined as the third direction (i.e., the third direction S3 as shown in FIG23 ); the center point of the positive projection of the baffle 130 on the plane where the pick-up and release port 13 is located along the third direction S3 is recorded as O; the reference line passing through the center point O, perpendicular to the third direction S3, and parallel to the baffle 130 is recorded as the first reference line L.

[0203] During the closing process of the door body 11, the flip beam 14 interacts with the baffle 130. Under the action of the flip beam 14, the baffle 130 moves along the second direction S2 through the guide rail assembly 400, locking the locking assembly 401 and placing the baffle 130 in the pre-locking position.

[0204] In some embodiments, during the door closing process, a center line of the orthographic projection of the baffle on the plane where the access opening is located is located within the projection of the flip beam on the plane where the access opening is located. The center line of the orthographic projection of the baffle on the plane where the access opening is located is perpendicular to the height direction of the refrigerator.

[0205] In some embodiments, when the door 11 is closing, the projection of the flip beam 14 on the plane where the access opening 13 is located overlaps with the first reference line L. Thus, when the door 11 is closed, the flip beam 14 interacts with the middle region of the baffle 130 along the third direction S3, so that the baffle 130 is subjected to a more balanced force. Under the force exerted on the baffle 130 by the flip beam 14 during its flipping, the baffle 130 moves along the second direction S2 via the guide rail assembly 400.

[0206] In some embodiments, during the closing process of the door body 11, the baffle 130 has not reached the pre-locking position. When the flip beam 14 flips around the flip axis M, a force is applied to the baffle 130, so that the baffle 130 moves along the second direction S2 to lock with the shell 110 and put the baffle 130 in the pre-locking position.

[0207] In some embodiments, during the closing process of the door body 11, the maximum displacement of the free end N into the storage chamber is recorded as W; when the baffle 130 and the shell 110 are in the pre-locked position, the distance between the front end of the baffle 130 and the plane where the access port 13 is located is recorded as D, and D is less than or equal to W.

[0208] It should be noted that during the closing process of the door body 11, the flip beam 14 can be completely flipped under the action of the door body, that is, during the closing process of the door body 11, W < D + (L0-L1). In this way, when the door body 11 is closed, the free end N enters the storage chamber, and the compression distance of the baffle 130 on the sealing element 140 is less than the deformation of the sealing element 140, thereby ensuring that the flip beam 14 can flip into place during the closing process of the door body 11.

[0209] In some embodiments, when the baffle 130 moves to the first position along the second direction S2 under the action of an external driving force, the external driving force is removed, and the baffle 130 continues to move along the second direction S2 under the action of inertia force and reaches the pre-locking position, completing the locking of the baffle 130 and the shell 110.

[0210] When the baffle 130 is in the first position, the distance between the front end of the baffle 130 and the plane of the access opening 13 is denoted as D1. D1 is less than D, and D1 is equal to W. Thus, during the closing process of the door body 11, the door body 11 pushes the baffle 130 in the second direction, causing the baffle 130 to reach the first position. At this point, the displacement of the free end N entering the storage chamber reaches its maximum. The flip beam 14 continues to flip, and the displacement of the free end N entering the storage chamber decreases. Under the action of inertia, the baffle 130 continues to move in the second direction S2 and reaches the pre-locked position.

[0211] In some embodiments, D1 is less than or equal to W, and W is less than or equal to D. Thus, during the closing process of the door body 11, the door body 11 pushes the baffle 130 to move in the second direction S2. After the baffle 130 reaches the first position and before reaching the pre-locking position, the displacement of the free end N of the baffle 130 into the storage chamber reaches its maximum. The flip beam 14 continues to flip, and the displacement of the free end N of the flip beam 14 into the storage chamber decreases. Under the action of inertia, the baffle 130 continues to move in the second direction S2 and reaches the pre-locking position.

[0212] The refrigerator 1 provided by some embodiments of the present disclosure can utilize the flipping of the flip beam 14 to lock the baffle 130 that has not reached the pre-locking position with the shell 110 to the pre-locking position by changing the relative position of the flip beam 14 and the baffle 130, thereby preventing the baffle 130 and the shell 110 from failing to reach the pre-locking state due to insufficient thrust when the user opens or closes the door body 11, thereby preventing the pre-seal from failing. This can further avoid the ineffective operation of the exhaust device, which is beneficial to reducing the energy consumption and noise of the refrigerator 1.

[0213] In some embodiments, as the vacuuming is carried out, the baffle 130 and the housing 110 act to compress the sealing element 140 to the vacuum sealing distance L3 to achieve the vacuum sealing condition.

[0214] In some embodiments, refrigerator 1 further includes a position sensor disposed on baffle 130 and configured to determine whether baffle 130 has reached a position that compresses sealing element 140 to a vacuum sealing distance L3. When baffle 130 and housing 110 interact to compress sealing element 140 to a vacuum sealing distance L3, the position sensor is triggered, and vacuum pump 210 exits the first state and operates in the second state.

[0215] In some embodiments, when the baffle 130 acts on the shell 110 to compress the sealing element 140 to the vacuum sealing distance L3, at least one of the parameters such as the time required, the air pressure in the storage device 100, the air pressure change rate, the current of the vacuum pump 210, and the exhaust flow rate of the vacuum pump 210 serves as a judgment condition for the vacuum pump 210 to end the first state operation and start the second state operation.

[0216] For example, when the baffle 130 and the shell 110 act to compress the sealing element 140 to the vacuum sealing distance L3, when the air pressure in the corresponding storage device 100 drops to a set value, it indicates that the difference between the external ambient air pressure and the air pressure in the storage device 100 reaches a value that causes the baffle 130 and the shell 110 to squeeze the sealing element 140 to achieve a vacuum sealing condition.

[0217] For example, the baffle 130 and the housing 110 squeeze the sealing element 140 . As the pumping time increases, the air pressure in the storage device 100 decreases, the pumping resistance of the vacuum pump 210 increases, and the current of the vacuum pump 210 increases accordingly.

[0218] In some embodiments, when the baffle 130 is closed to the pre-locked position, the vacuum pump 210 operates in a first state. As the air pressure within the storage device 100 decreases, the baffle 130 continues to move in the second direction S2. When the baffle 130 and the housing 110 interact to compress the sealing element 140 to a vacuum sealing distance L3, the vacuum pump 210 begins to operate in a second state. The amount of air pumped (displaced) by the vacuum pump 210 in the first state is greater than the amount of air pumped (displaced) by the vacuum pump 210 in the second state, thereby ensuring that the air pressure within the storage chamber meets vacuum sealing conditions.

[0219] In some embodiments, when the vacuum pump 210 operates in the first state, the rotational speed of the vacuum pump 210 is a first rotational speed V1. When the vacuum pump 210 operates in the second state, the rotational speed of the vacuum pump 210 is a second rotational speed V2. The second rotational speed V2 is less than the first rotational speed V1. For example, the rated rotational speed of the vacuum pump 210 is denoted as V0, V1 is any value between 0.8 times V0 and V0, and V2 is any value between 0.5 times V0 and 0.8 times V0.

[0220] In some embodiments, when the vacuum pump 210 operates in the first state, the power of the vacuum pump 210 is a first power P1. When the vacuum pump 210 operates in the second state, the power of the vacuum pump 210 is a second power P2. The second power P2 is less than the first power P1. For example, the rated power of the vacuum pump 210 is denoted as P0, P1 is any value between 0.8 times P0 and P0, and P2 is any value between 0.5 times P0 and 0.8 times P0.

[0221] It is understood that during vacuuming, the vacuum pump 210 first operates in a first state at a higher speed and / or power to extract air from the storage chamber 112. This ensures that the amount of air extracted by the vacuum pump 210 exceeds the amount of air entering the storage chamber 112 from the external environment, thereby ensuring that the air pressure within the storage chamber meets the vacuum sealing conditions. In this case, the vacuum pump 210 then operates in a second state, reducing the extraction rate. This reduces the operating noise of the vacuum pump 210 and improves the user experience.

[0222] In some embodiments, as shown in FIG3 , the storage device 100 further includes a cover assembly 150. The cover assembly 150 is disposed on an upper portion of the housing 110 and is connected to the housing 110. The cover assembly 150 includes at least one operating button 151. For example, the operating button 151 is configured to turn the vacuum device 200 on or off, thereby facilitating user control of the storage device 100. For example, the operating button 151 is also configured to control the on / off state of the ventilation device 300 to control the connection and disconnection between the storage chamber 112 and the outside.

[0223] FIG. 24 is an exploded view of a storage device of a refrigerator according to some embodiments.

[0224] In some embodiments, as shown in Figure 24, the ventilation device 300 is an electronic ventilation device, that is, the ventilation device 300 includes an electronic ventilation valve. The controller is also configured to open or close the control ventilation device 300 to connect or disconnect the storage chamber 112 with the external environment. The storage device 100 also includes a modified atmosphere membrane assembly 160. The modified atmosphere membrane assembly 160 is arranged at the position of the air extraction port connected to the vacuum pump 210 and the storage chamber 112, and the air extraction port is blocked. The modified atmosphere membrane assembly 160 is configured to promote the oxygen in the air to pass through the modified atmosphere membrane assembly 160 when the vacuum pump 210 extracts the air in the storage chamber 112.

[0225] For example, the modified atmosphere membrane assembly 160 includes a nitrogen-oxygen separation membrane 161 . Thus, when the vacuum pump 210 is operating, a pressure difference can be quickly formed on both sides of the nitrogen-oxygen separation membrane 161 to extract oxygen from the storage chamber 112 .

[0226] It should be noted that the nitrogen-oxygen separation film 161 has oxygen-affinity groups. Oxygen is more easily attached to oxygen-affinity groups than nitrogen, carbon dioxide, etc. Therefore, the nitrogen-oxygen separation film 161 can facilitate the extraction of oxygen from the storage chamber 112 by the vacuum pump 210.

[0227] In some embodiments, as shown in FIG24 , the housing 110 further includes an air extraction port 116 and an adapter plate 117. The air extraction port 116 is disposed in and extends through the housing rear wall 113. The adapter plate 117 is located on a side of the nitrogen-oxygen separation membrane 161 away from the storage chamber 112 and is fixedly connected to the housing rear wall 113. The air extraction end of the air extraction pipeline of the air extraction device 200 is located between the nitrogen-oxygen separation membrane 161 and the adapter plate 117 to extract oxygen adhering to the nitrogen-oxygen separation membrane 161.

[0228] When the baffle 130 is closed to the pre-locking position, the ventilation device 300 is opened, and the storage chamber 112 is connected to the external environment. The vacuum pump 210 starts to evacuate air, and the nitrogen-oxygen separation membrane 161 can promote the oxygen in the storage chamber 112 to be extracted by the vacuum pump 210. When the vacuum pump 210 evacuates air for a preset time, a low-oxygen environment is formed in the storage chamber 112. In this case, the ventilation device 300 is closed, the storage chamber 112 is isolated from the external environment, the vacuum pump 210 continues to work, and the air pressure in the storage chamber 112 continues to decrease, eventually forming a low-oxygen and low-pressure storage environment, thereby effectively extending the shelf life of the food in the storage chamber 112.

[0229] In some embodiments, the operation mode of the storage device 100 includes at least one storage mode, and the at least one storage mode includes a normal pressure and low oxygen mode, a low pressure mode, and a low oxygen and low pressure mode.

[0230] When the storage device 100 operates in the normal pressure hypoxia mode, the ventilation device 300 is opened, the storage chamber 112 is connected to the outside, and the vacuum pump 210 works to reduce the oxygen content in the storage chamber 112, thereby forming a hypoxic storage environment in the storage chamber 112.

[0231] It can be understood that the normal pressure and low oxygen mode is suitable for storing food with a large transpiration area (such as leafy vegetables) and food with high humidity (such as fruits). This mode can reduce the respiration of stored food, preserve nutrients, reduce transpiration loss, and improve freshness.

[0232] When the storage device 100 operates in low-pressure mode, the ventilation device 300 is closed, the storage chamber 112 is isolated from the external environment, and the vacuum pump 210 works to reduce the air pressure in the storage chamber 112 , thereby forming a low-pressure storage environment in the storage chamber 112 .

[0233] It is understandable that the low-pressure mode is suitable for storing dry ingredients (such as dried fruits, tea, grains, etc.). This mode can reduce the respiration of dry ingredients, preserve nutrients, and extend the shelf life.

[0234] When storage device 100 is in low-oxygen, low-pressure mode, baffle 130 is closed, the ventilation device is open, and storage chamber 112 is connected to the external environment. When vacuum pump 210 continues pumping for a predetermined period of time, a low-oxygen environment is created within storage chamber 112. In this state, the ventilation device is closed, isolating storage chamber 112 from the external environment. Vacuum pump 210 continues operating to reduce the pressure within storage chamber 112, creating a low-oxygen, low-pressure storage environment.

[0235] It is understandable that the low oxygen and low pressure mode is suitable for storing most foods. This mode can reduce the reproduction rate of microorganisms in the storage cavity 112, thereby extending the shelf life of the food.

[0236] In some embodiments, the refrigerator 1 further includes an ingredient identification device. The ingredient identification device is disposed on the door 11. The ingredients are provided with RFID-based tags that store information corresponding to the ingredients. The ingredient identification device is configured to identify the tags and the information within them, and, based on the ingredient type, determine the appropriate storage mode for the ingredient corresponding to the tag, such as the normal pressure and low oxygen mode, the low pressure mode, or the low oxygen and low pressure mode.

[0237] For example, the food identification device includes a scanning component configured to scan a label on the food to obtain information on the label. For example, the food information on the label includes the name of the food, the type (e.g., high moisture, dry, medium moisture, etc.), and the quantity (e.g., weight, quantity).

[0238] In some embodiments, the operation mode of the storage device 100 further includes a vacuum pickling mode. For example, the at least one operation button 151 further includes an operation button 151 for controlling the storage device 100 to operate in the vacuum pickling mode.

[0239] When the storage device 100 operates in vacuum curing mode, the baffle 130 is closed and the vacuum pump 210 operates to raise the pressure in the storage chamber 112 to a first pressure value and maintain the first pressure value for a first period of time. This maintains a low-pressure environment in the storage chamber 112. In this low-pressure environment, the intracellular pressure of the seasoned food is greater than the pressure in the storage chamber 112.

[0240] When the pressure in storage chamber 112 remains at the first pressure value for a first period of time, ventilation device 300 opens, connecting storage chamber 112 to the outside world. The pressure in storage chamber 112 rises to a second pressure value, and the ventilation device closes, maintaining the second pressure value for a second period of time. In this state, the difference between the intracellular pressure of the seasoned food and the pressure in storage chamber 112 decreases.

[0241] When the pressure in storage chamber 112 remains at the second pressure value for a second time period, the ventilation device closes, disconnecting storage chamber 112 from the outside world. Vacuum pump 210 operates to increase the pressure in storage chamber 112 to the first pressure value and maintains it for the first time period. This cycle repeats, maintaining the first pressure value for the first time period and then maintaining the second pressure value for the second time period, thereby marinating the food in storage chamber 112.

[0242] It can be understood that in the environment of the first pressure value, the pressure difference between the intracellular pressure of the food and the pressure in the storage chamber 112 becomes larger, while in the environment of the second pressure value, the pressure difference between the intracellular pressure of the food and the pressure in the storage chamber 112 becomes smaller. In this way, the change of the food in the environment of two pressure values ​​can accelerate the rupture of the cell wall, thereby promoting external substances (seasonings) to enter the cells, which is conducive to the flavor of the food.

[0243] In some embodiments, the first pressure value is any value between 0.7 atm and 0.8 atm, and the second pressure value is any value between 0.9 atm and 1 atm.

[0244] In some embodiments, the operation mode of the storage device 100 further includes a vacuum fermentation mode. For example, the at least one operation button 151 further includes an operation button 151 for controlling the storage device 100 to operate in the vacuum fermentation mode.

[0245] When the storage device 100 operates in vacuum fermentation mode, the ventilation device is open, the storage chamber 112 is connected to the outside, and the vacuum pump 210 operates for a preset oxygen reduction time. The ventilation device is then closed to reduce the oxygen content in the storage chamber 112, creating a low-oxygen storage environment. For example, the oxygen reduction time can be anywhere from 30 minutes to 60 minutes.

[0246] It is understood that in a low-oxygen storage environment, anaerobic bacteria (such as lactic acid bacteria) are used for anaerobic respiration and fermentation. For example, when the anaerobic bacteria are lactic acid bacteria, the incomplete oxidation product after oxidation is lactic acid, which undergoes lactic acid fermentation.

[0247] It should be noted that the oxygen reduction process in the vacuum fermentation mode is similar to the oxygen reduction process in the aforementioned normal pressure and low oxygen mode, and will not be described in detail here.

[0248] In some embodiments, when the storage device 100 operates in a vacuum fermentation mode, the storage device 100 does not perform refrigeration, thereby maintaining the storage chamber 112 in a room temperature and low oxygen environment, which is beneficial to improving the fermentation efficiency of anaerobic bacteria.

[0249] In some embodiments, storage device 100 further includes a heating device. The heating device is configured to heat the air within storage chamber 112 to increase the temperature of storage chamber 112. When storage device 100 operates in vacuum fermentation mode, the heating device operates to increase the temperature within storage chamber 112, thereby maintaining a high-temperature, low-oxygen environment within storage chamber 112, increasing the anaerobic respiration efficiency of anaerobic bacteria and further improving the fermentation efficiency of anaerobic bacteria.

[0250] Specifically, the wires that carry power to the current power supply assembly 500 are directly installed in the wire fixing portion. The arrangement of the wire fixing portion results in low sealing of the storage device, which makes it easy for external gas to enter the storage device 100 through the wire fixing portion, resulting in the low-pressure state of the storage device 100 being unable to be maintained for a long time. The storage device 100 is a sealed environment, which is prone to the growth of bacteria. In order to maintain the cleanliness of the storage device 100, its internal environment needs to be sterilized. In addition, the storage device 100 is a sealed environment. When odorous food ingredients are placed in it, the odor cannot be dissipated, resulting in a high odor concentration. It needs to be deodorized to form a clean and odorless storage space.

[0251] FIG25 is an exploded view of a storage device of a refrigerator according to some embodiments at another viewing angle; FIG26 is an exploded view of a storage device of a refrigerator according to some embodiments at yet another viewing angle.

[0252] In some embodiments, as shown in Figures 25 and 26, the storage device 100 further includes a power supply assembly 500, which is disposed on an adapter plate 117. The power supply assembly 500 is electrically connected to the electrical devices in the storage device 100 and an external power source, respectively, to provide power to the electrical devices in the storage device 100. The electrical devices in the storage device 100 include a discharge assembly, an ion generation assembly, and a light sterilization assembly. The adapter plate 117 is detachably connected to the housing 110, facilitating inspection of the power supply assembly 500.

[0253] In some embodiments, as shown in FIG. 25 and FIG. 26 , the storage device 100 further includes a first sealing ring 170 , which is disposed between the adapter plate 117 and the rear wall 113 of the housing, thereby sealingly connecting the adapter plate 117 to the rear wall 113 of the housing.

[0254] FIG. 27 is an exploded view of an adapter plate and a power-on component of a refrigerator according to some embodiments; FIG. 28 is an exploded view of an adapter plate and a power-on component of a refrigerator according to some embodiments.

[0255] 27 and 28 , the energization assembly 500 includes at least one conductive member 510 and at least one sealing member 520. The at least one conductive member 510 and the at least one sealing member 520 correspond to each other.

[0256] The conductive member 510 includes a first conductive portion 511 and a second conductive portion 512. The first conductive portion 511 extends into the storage cavity 112 to electrically connect to the electrical device in the storage cavity 112. The second conductive portion 512 is located outside the housing 110 and is connected to a power source, thereby allowing the power source to supply power to the conductive member 510 and the electrical device.

[0257] The sealing member 520 is located outside the housing 110 and is disposed between the conductive member 510 and the housing 110 to seal a gap between the conductive member 510 and the housing 110 .

[0258] It can be understood that when the vacuum pump 210 is working, the pressure in the storage chamber 112 decreases. Since the seal 520 is located on the outside of the shell 110, the pressure on the side of the seal 520 close to the shell 110 is less than the pressure on the side of the seal 520 away from the shell 110. Therefore, under the action of the pressure difference on both sides of the seal 520, the seal 520 approaches the shell 110 and further seals the gap between the conductive part 510 and the shell 110, which is beneficial to improve the sealing performance of the seal 520.

[0259] In addition, under the action of the pressure difference on both sides of the sealing member 520 , the sealing member 520 will shrink toward the radial inner side of the conductive member 510 , thereby increasing the fit between the sealing member 520 and the conductive member 510 .

[0260] In some embodiments, as shown in FIG28 , the adapter plate 117 includes a first mounting hole 1171 and a second mounting hole 1172. The at least one conductive member 510 includes two conductive members 510. The two conductive members 510 are disposed in the first mounting hole 1171 and the second mounting hole 1172, respectively. For example, the conductive member 510 disposed in the first mounting hole 1171 is connected to the positive terminal of the power supply, while the conductive member 510 disposed in the second mounting hole 1172 is connected to the negative terminal of the power supply.

[0261] In some embodiments, as shown in FIG28 , the conductive member 510 further includes a third fixing portion 513, and the first conductive portion 511 and the second conductive portion 512 are respectively disposed on opposite sides of the third fixing portion 513. A sealing member 520 is disposed between the third fixing portion 513 and the housing 110, and is sleeved on the outer circumference of the first conductive portion 511. Thus, the sealing member 520 can block the gap between the first conductive portion 511 and the housing 110, as well as the gap between the third fixing portion 513 and the housing 110, thereby improving the reliability of the seal between the conductive member 510 and the housing 110.

[0262] 27 and 28 , the power supply assembly 500 further includes a pressure cap 530 . The pressure cap 530 is disposed on a side of the third fixing portion 513 away from the housing 110 and is configured to accommodate the third fixing portion 513 of the conductive member 510 and fix the third fixing portion 513 to the adapter plate 117 .

[0263] For example, the gland 530 includes a pressure plate 531 and at least one fifth connecting plate 532. The pressure plate 531 is annular and is positioned around the outer periphery of the second conductive portion 512. The pressure plate 531 mates with the third fixing portion 513 of the conductive member 510 and is configured to accommodate the third fixing portion 513. The at least one fifth connecting plate 532 is spaced apart and disposed around the outer periphery of the pressure plate 531 and is fixedly connected to the adapter plate 117. For example, the connecting plate 532 is fixedly connected to the adapter plate 117 using fasteners such as screws.

[0264] It can be understood that when the connecting plate 532 is fixedly connected to the adapter plate 117, the pressure plate 531 will apply a certain force to the third fixed part 513, so that the pressure plate 531 squeezes the third fixed part 513 and the seal 520, thereby increasing the force between the seal 520 and the third fixed part 513, as well as the force between the seal 520 and the adapter plate 117, which is beneficial to improving the reliability of the seal between the conductive part 510 and the shell 110.

[0265] In some embodiments, the adapter plate 117 is sealed to the housing 110 via a sealing ring.

[0266] In some embodiments, screw columns are provided at positions surrounding the first mounting hole 1171 and the second mounting hole 1172 on the adapter plate 117, and screw holes are provided on the fifth connecting plate 532 on the pressure cover 530. The screws pass through the screw holes on the fifth connecting plate 532 and the screw columns on the shell 110, so that the pressure cover 530 can be fixedly connected to the adapter plate 117.

[0267] 27 and 28 , the housing 110 further includes a second receiving portion 118. The second receiving portion 118 is formed on the adapter plate 117 and is located on a side of the adapter plate 117 away from the storage cavity 112. A first mounting hole 1171 and a second mounting hole 1172 are provided in the second receiving portion 118.

[0268] The power supply assembly 500 also includes a protective cover 540. The protective cover 540 is disposed on a side of the second accommodating portion 118 that is away from the storage cavity 112. The protective cover 540 covers the second accommodating portion 118 and cooperates with the second accommodating portion 118 to form a storage cavity. The protective cover 540 is configured to protect the components in the second accommodating portion 118 and prevent damage to the power supply assembly 500 from moisture and other factors within the storage chamber.

[0269] In some embodiments, as shown in FIG27 , the energization assembly 500 further includes a fourth sealing portion 550 . The fourth sealing portion 550 is disposed between the shield 540 and the second accommodating portion 118 and is configured to close the gap between the shield 540 and the second accommodating portion 118 , thereby sealing the accommodating cavity. This further reduces the impact of the storage room environment on the energization assembly 500. For example, the fourth sealing portion 550 may be a sealing strip.

[0270] In some embodiments, the storage device 100 further includes a lighting assembly, which is disposed in the storage cavity 112 . The lighting assembly is electrically connected to the first conductive portions 511 of the two conductive members 510 and is configured to illuminate the storage cavity 112 .

[0271] 29 is an exploded view of an adapter plate, a power supply assembly, and an ion generating assembly of a refrigerator according to some embodiments.

[0272] 26 and 29 , the storage device 100 further includes an ion generating assembly 600 . The ion generating assembly 600 is disposed in the storage chamber 112 and is configured to discharge electricity and generate ions to sterilize and deodorize the storage chamber 112 .

[0273] The ion generating assembly 600 includes a first circuit board 610 and a discharge component 620. The first circuit board 610 is electrically connected to the discharge component 620, and the first circuit board 610 is also electrically connected to the first conductive portions 511 of the two conductive members 510 to power the discharge component 620. When energized, the discharge component 620 discharges electricity, achieving both sterilization and deodorization.

[0274] It can be understood that the ion generating component 600 and the power-on component 500 are both arranged on the adapter plate 117, so that the ion generating component 600 and the power-on component 500 can be detachably connected to the shell 110 through the adapter plate 117, which is convenient for detecting the ion generating component 600 and the power-on component 500, and also convenient for installing the ion generating component 600 and the power-on component 500.

[0275] In some embodiments, the discharge component 620 may operate in a first discharge mode or in a second discharge mode.

[0276] When the discharge component 620 operates in the first discharge mode, it generates corona to ionize the air into a variety of strong oxidizing substances, including ozone, atomic oxygen, ground state oxygen, etc. These strong oxidizing substances can absorb odor molecules and microorganisms in the storage chamber 112, achieving the effects of deodorization and sterilization.

[0277] When the discharge component 620 operates in the second discharge mode, the discharge component 620 discharges into the air to ionize the air into positive and negative ion groups. The positive and negative ion groups have a killing effect on microorganisms and can play a role in disinfection and sterilization.

[0278] In some embodiments, the housing 110 further includes a third receiving portion 119, which is disposed on a side of the adapter plate 117 adjacent to the storage cavity 112. The third receiving portion 119 is annular and surrounds the first circuit board 610, the first mounting hole 1171, and the second mounting hole 1172.

[0279] The housing 110 also includes a protective cover 1101. This cover is positioned on a side of the third accommodating portion 119 away from the adapter plate 117 and is mounted on an end of the third accommodating portion 119. The protective cover 1101 cooperates with the third accommodating portion 119 to define a storage chamber that protects the power supply assembly 500 and the first circuit board 610 from damage caused by moisture and other factors within the storage chamber 112.

[0280] It is understandable that the discharge component 620 is located outside the accommodating cavity, and the first circuit board 610 is arranged in the accommodating cavity, so as to prevent the ions released by the discharge component 620 during discharge from corroding the first circuit board 610 and preventing the first circuit board 610 from being damaged.

[0281] In some embodiments of the present disclosure, a third accommodating portion 119 is provided on the shell 110, thereby increasing the sealing reliability and stability of the storage device 100, and facilitating protection of the power supply component 500 and the first circuit board 610, which is beneficial to improving the stability of the operation of the ion generating component.

[0282] Figure 29 is an exploded view of the adapter plate, power-on component and ion generating component of the refrigerator according to some embodiments; Figure 30 is an exploded view of the adapter plate, power-on component and atmosphere-controlled membrane component of the refrigerator according to some embodiments.

[0283] In some embodiments, as shown in FIG. 29 and FIG. 30 , the modified atmosphere membrane assembly 160 is disposed on a side of the adapter plate 117 close to the storage chamber 112 and located on a side of the ion generating assembly 600 .

[0284] For example, referring to Figure 30, the adapter plate 117 includes a first accommodating portion 1173, which is arranged on one side of the ion generating assembly 600, and the nitrogen-oxygen separation membrane 161 is arranged in the first accommodating portion 1173 to adsorb the oxygen in the storage chamber 112, which is then extracted by the exhaust device 200, thereby reducing the oxygen concentration in the storage chamber 112.

[0285] 31 is an exploded view of an adapter plate, a power supply assembly, and an ion generating assembly of a refrigerator according to some embodiments.

[0286] In some embodiments, as shown in Figures 29 and 31 , the housing 110 further includes a second sealing portion 1102. The second sealing portion 1102 is disposed at the interface between the protective cover 1101 and the second receiving portion 118 to seal the gap between the protective cover 1101 and the third receiving portion 119, thereby reducing the impact of the storage cavity 112 on the power-on component 500 and the first circuit board 610. For example, the second sealing portion 1102 is a sealing strip.

[0287] In some embodiments, when the vacuum pump 210 is working, the discharge component 620 is not working, thereby preventing the ions generated by the discharge component 620 from being drawn out by the vacuum pump 210 and reducing the sterilization and deodorization effects.

[0288] In some embodiments, when the storage device 100 is opened and then closed, the ventilation device is closed, the discharge component 620 is activated, and continues to work for the first discharge time, thereby sterilizing and deodorizing the storage cavity 112.

[0289] After the discharge component 620 operates for the first discharge time, the discharge component 620 stops operating. In this case, the ventilation device is closed, the vacuum pump 210 is started, and the pressure in the storage chamber 112 is reduced, forming a low-pressure environment.

[0290] When the pressure in the storage chamber 112 reaches the second pressure value due to slow gas leakage, the vacuum pump 210 operates to reduce the pressure in the storage chamber 112 to the first pressure value.

[0291] When the pressure in the storage chamber 112 drops to the first pressure value, the vacuum pump 210 stops working to complete the pressure reduction. The discharge component 620 starts and continues to work for a second discharge time period, wherein the second discharge time period is shorter than the first discharge time period.

[0292] It is understandable that when the baffle 130 is opened, air carrying floating bacteria from the outside will be brought into the storage cavity 112, or new food will be put into the storage cavity 112. In this case, the discharge component 620 continues to discharge for the first discharge time to perform a strong sterilization on the closed storage cavity 112.

[0293] When baffle 130 remains closed, the pressure in storage chamber 112 gradually increases due to air leakage. After the vacuum pump reduces the pressure in storage chamber 112, the air composition in storage chamber 112 changes little. In this case, the discharge component 620 continues to discharge for the second discharge duration, achieving the sterilization purpose while also reducing energy consumption.

[0294] In some embodiments, when the storage device 100 keeps the baffle 130 closed for the first closing time period, the discharge component 620 is activated and continues to operate for the first discharge time period to strongly sterilize the storage cavity 112 .

[0295] For example, the first closing time can be set to 2 days. It is understandable that if the storage device 100 remains closed for a long time, bacteria may grow. In this case, the discharge component 620 continues to work for the first closing time, which can effectively sterilize the storage environment in the current storage cavity 112.

[0296] In some embodiments, when the storage device 100 keeps the baffle 130 closed for the first closing time period, the vacuum pump 210 is activated to extract at least a portion of the contaminated gas in the storage chamber 112 .

[0297] In some embodiments, the storage device 100 further includes an odor sensor disposed within the storage cavity 112 and configured to detect and identify gas components. For example, the odor sensor can determine the source and concentration of an odor based on the chemical composition of the gas. For example, the odor sensor can identify substances such as volatile amines and determine their concentration.

[0298] In some embodiments, when the odor concentration within the storage chamber 112 reaches a first odor-purifying concentration, the discharge component 620 is activated and continues to operate for the first odor-purifying duration. While the discharge component 620 is operating, the ventilation device is closed, disconnecting the storage chamber 112 from the outside world. The discharge component 620 discharges the sealed storage chamber 112 to purify the gas within.

[0299] In some embodiments, when the odor concentration within storage chamber 112 reaches a first odor-purifying concentration and the duration of the last vacuuming operation has not yet reached the first pressure-maintaining duration, discharge component 620 activates and continues operating for the first odor-purifying duration. While discharge component 620 is operating, the ventilation device closes, disconnecting storage chamber 112 from the outside world. Discharge component 620 discharges the sealed storage chamber 112 to purify the gas within.

[0300] When the odor concentration in storage chamber 112 reaches the first odor-free concentration and the duration of the last vacuuming operation reaches the second pressure-holding duration, the ventilation device shuts down and vacuum pump 210 starts operating for the first vacuuming duration. After vacuum pump 210 stops operating, discharge component 620 starts operating for the second odor-free duration. The second pressure-holding duration is greater than the first pressure-holding duration.

[0301] For example, the first holding pressure time period is any value between 3 and 5 hours, and the second holding pressure time period is any value between 10 and 12 hours.

[0302] It is understandable that when the holding time after vacuuming reaches the second holding time, due to the long holding time, it is close to the start of the next vacuuming. In this case, vacuuming is performed first, and then discharge deodorization is performed to prevent the ion groups or ozone released by discharge deodorization from being extracted after the discharge releases ions, which will weaken the deodorization effect when vacuuming is started next time.

[0303] In some embodiments, when deodorizing, when the discharge component 620 continues to work for a first deodorizing time (such as 20 minutes), and the odor concentration recognized by the odor sensor is higher than the second deodorizing concentration, the discharge component 620 stops working.

[0304] Furthermore, when the storage device 100 remains closed, the odor sensor no longer detects odors in real time. Instead, it detects odors once every set odor detection time. If the odor concentration within the storage chamber 112 reaches a first odor-clearing concentration, the discharge component 620 activates and continues operating for the first odor-clearing time. This odor-clearing process continues until the next time the storage device 100 is opened, with the time-controlled discharge odor-clearing process continuing. The second odor-clearing concentration is lower than the first odor-clearing concentration.

[0305] For example, the second clean taste concentration is 0.8 times to 0.9 times the first clean taste concentration.

[0306] In some embodiments, the operating modes of the storage device 100 also include a low-pressure preservation mode, a sterilization preservation mode, and a deodorization preservation mode.

[0307] When the storage device 100 operates in the sterilization and freshness preservation mode, the discharge component 620 discharges in the second discharge mode. When the storage device 100 operates in the odor removal and freshness preservation mode, the discharge component 620 discharges in the first discharge mode.

[0308] For example, the low-pressure fresh-keeping mode can be used to store dry ingredients, thereby achieving an antioxidant effect. The sterilization and fresh-keeping mode can be used to store maternal and infant food to maintain the freshness of the ingredients. The odor-free fresh-keeping mode can be used to store ingredients with strong odors, thereby keeping the air in the storage chamber 112 fresh.

[0309] FIG32 is a structural diagram of a storage device and a photodynamic sterilization module of a refrigerator according to some embodiments; FIG33 is an exploded view of an adapter plate, a power supply component, and a photodynamic sterilization module of a refrigerator according to some embodiments;

[0310] 32 and 33 , the storage device 100 further includes a light sterilization component 700 . The light sterilization component 700 is disposed in the storage cavity 112 and is configured to emit light to kill bacteria in the storage cavity 112 .

[0311] The light sterilization assembly 700 includes a second circuit board 710 and a light-emitting component 720. The second circuit board 710 is connected to the two conductive members 510, and the light-emitting component 720 is connected to the second circuit board 710. This allows an external power source to supply power to the light-emitting component 720 via the conductive members 510 and the second circuit board 710. When powered, the light-emitting component 720 is configured to emit blue-violet light to kill bacteria. For example, the wavelength of the blue-violet light ranges from 390 nm to 420 nm.

[0312] It is understandable that the blue-violet light with a wavelength between 390nm and 420nm emitted by the light-emitting component 720 can destroy the molecular structure of deoxyribonucleic acid or ribonucleic acid in bacteria or viruses, thereby achieving a sterilization and disinfection effect.

[0313] 34 is a perspective view of a storage device and a light sterilization assembly of a refrigerator according to some embodiments.

[0314] In some embodiments, as shown in Figures 32 to 34 , the adapter plate 117 is located above the storage cavity 112, that is, the adapter plate 117 is disposed on the top wall of the housing 110. The germicidal light assembly 700 is disposed on a side of the adapter plate 117 near the storage cavity 112, thereby facilitating the light emitting component 720 to emit light and illuminate various areas within the storage cavity 112.

[0315] For example, the adapter plate 117 is disposed at the geometric center of the top wall of the housing 110 , and the germicidal light assembly 700 is disposed at the geometric center of the adapter plate 117 .

[0316] It is understandable that the light sterilization component 700 is disposed on the adapter plate 117 so that the light sterilization component 700 can be detachably connected to the housing 110 through the adapter plate 117, thereby facilitating the detection of the light sterilization component 700 and facilitating the installation of the light sterilization component 700.

[0317] In some embodiments, the air extraction port 116 is formed on the top wall of the housing 110 , and the adapter plate 117 blocks the air extraction port 116 .

[0318] 35 is a perspective view of a housing and a light sterilization assembly of a storage device of a refrigerator according to some embodiments; FIG36 is a cross-sectional view of a housing and a light sterilization assembly of a storage device of a refrigerator according to some embodiments.

[0319] In some embodiments, as shown in Figures 35 and 36 , the light sterilization assembly 700 further includes a glass plate 730. The glass plate 730 is located on a side of the light-emitting component 720 that is adjacent to the storage cavity 112. Light emitted by the light-emitting component 720 passes through the glass plate 730 and enters the storage cavity 112. The glass plate 730 protrudes toward the storage cavity 112 and is configured to converge the light emitted by the light-emitting component 720.

[0320] In some embodiments, the light sterilization assembly 700 further includes a cover 740 . The cover 740 is disposed on a side of the light emitting component 720 away from the storage cavity 112 to protect the light emitting component 720 .

[0321] In some embodiments, the light sterilization assembly 700 further includes a mounting portion 750, which abuts against the side of the glass plate 730 adjacent to the storage cavity 112.
