Description

Technical Field

[0001] The embodiments of the present application relate to refrigeration technology, and more particularly to a refrigerator. Background Art

[0002] A vacuum refrigerator is a refrigerator that can form a negative pressure environment inside the refrigerator. Specifically, it can form a negative pressure environment in the refrigerator or freezer, thereby reducing the oxygen content in the air in the refrigerator compartment so that the food can be better preserved in the refrigerator. Because the refrigerator compartment is in a negative pressure environment, the atmospheric pressure outside the compartment will press the refrigerator door, making it impossible to open the refrigerator door. Therefore, the refrigerator compartment needs to be pressurized to balance the air pressure inside and outside the compartment before the door can be opened. However, when the compartment is in a negative pressure environment for a long time, the door is pressed against the refrigerator body for a long time, which will cause the door to stick to the refrigerator, making it difficult to open the door.

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] A vacuum refrigerator is a refrigerator that can form a negative pressure environment inside the refrigerator. Specifically, it can form a negative pressure environment in the refrigerator or freezer, thereby reducing the oxygen content in the air in the refrigerator compartment so that the food can be better preserved in the refrigerator. Because the refrigerator compartment is in a negative pressure environment, the atmospheric pressure outside the compartment will press the refrigerator door, making it impossible to open the refrigerator door. Therefore, the refrigerator compartment needs to be pressurized to balance the air pressure inside and outside the compartment before the door can be opened. However, when the compartment is in a negative pressure environment for a long time, the door is pressed against the refrigerator body for a long time, which will cause the door to stick to the refrigerator, making it difficult to open the door.

[0052] In the refrigerator proposed in the present application, the storage cavity of the drawer can be used to store food that needs to be refrigerated or frozen for preservation. When the storage cavity of the drawer is located in the box, the vacuum component evacuates the storage cavity, which can reduce the oxygen content of the air in the storage cavity, so that the food in the storage cavity can be preserved for a longer time. The sealing component opens the air inlet on the drawer, so that the air outside the box can enter the storage cavity through the air inlet, thereby balancing the air pressure inside and outside the storage cavity, so that the drawer can be pulled out of the box, so that food can be taken and placed from the storage cavity. The drive component can drive the drawer to move, wherein, when the air pressure in the storage cavity of the drawer is not less than the air pressure outside the box, the atmosphere outside the box no longer presses the drawer, and at this time the drive component drives the drawer to move until the storage cavity is located outside the box, so that the user can more conveniently pull the drawer out of the box, making the use process of the refrigerator of the present application simple, convenient and labor-saving.

[0053] This application proposes a refrigerator, referring to Figures 1 to 3 As shown, it includes a box 100. Among them, the box 100 is the basic component of the refrigerator of the present application. The box 100 can provide a mounting base for at least part of other components of the refrigerator and protect at least part of other components. The box 100 can be made of metal material, so that the box 100 has a better structural strength, so that the refrigerator structure of the present application is stable. Of course, part of the box 100 can also be made of composite material, so that the box 100 can maintain a better structural strength and be relatively light in weight.

[0054] The box body 100 has a cavity 110 therein, and the cavity 110 of the box body 100 is a space for storing food. Other parts of the refrigerator, such as a compressor, an evaporator, a condenser and a fan, may also be arranged in other parts of the box body 100. These parts are connected to form a refrigeration assembly of the refrigerator, which can generate cold gas and transport the cold gas to the cavity 110, so that the refrigerator has a refrigeration function.

[0055] The refrigerator of the present application also includes a drawer 200, and the drawer 200 has a storage cavity 211. The storage cavity 211 of the drawer 200 can also be used to store food. The drawer 200 is movably arranged in the housing 100, so that the drawer 200 can also move relative to the housing 100. The drawer 200 is configured to be movable relative to the housing 100 so that the storage cavity 211 of the drawer 200 is completely located in the cavity 110 in the housing 100, or to be movable relative to the housing 100 so that at least part of the storage cavity 211 is located outside the cavity 110. Specifically, the housing 100 also has a plug port 120 connected to the cavity 110, and the cavity 110 has a bottom wall opposite to the plug port 120. The drawer 200 can be inserted into the housing 100 through the plug port 120 and move along a first direction toward the bottom wall of the cavity 110, that is, Figure 2 The drawer 200 moves in the X direction until the storage cavity 211 of the drawer 200 is completely in the receiving cavity 110, and the drawer 200 can block the plug interface 120 of the box 100, so that the storage cavity 211 can be enclosed in the box 100. The drawer 200 can also move in a second direction away from the bottom wall of the receiving cavity 110, that is, Figure 2 In the Y direction, the drawer 200 moves out of the box body 100, and at least a portion of the storage cavity 211 can be moved outside the box body 100, so that the food stored in the storage cavity 211 can be taken out.

[0056] refer to Figure 2As shown, the refrigerator of the present application further includes a vacuum assembly 300, which is disposed on the housing 100 and is configured to evacuate the storage cavity 211 of the drawer 200. Specifically, the vacuum assembly 300 may adopt a vacuum pump structure, and the vacuum assembly 300 has an exhaust pipe, which may be connected to the cavity 110 of the housing 100, and the vacuum pump may extract the gas in the cavity 110, so that the air pressure in the cavity 110 is reduced. It should be understood that the top of the drawer 200 has a take-out opening 212 connected to the storage cavity 211, and the take-out opening 212 is a normally open structure. When the storage cavity 211 of the drawer 200 is located in the cavity 110 of the box 100 as a whole, the take-out opening 212 of the drawer 200 is also located in the box 100, and the storage cavity 211 of the drawer 200 is connected to the cavity 110 of the box 100 through the take-out opening 212, and the box 100 can block the take-out opening 212 from the outside of the box 100. Therefore, when the vacuum assembly 300 evacuates the cavity 110 of the box 100, the storage cavity 211 connected to the cavity 110 can be evacuated together, so that the amount of gas in the storage cavity 211 can be reduced, and accordingly, the oxygen content in the storage cavity 211 can be reduced. It should be understood that since oxygen can aggravate the oxidation of food, too high a content of oxygen is not conducive to food preservation. By reducing the oxygen content in the storage cavity 211, the food in the storage cavity 211 can be preserved for a longer time, so that the refrigerator of the present application has a better food preservation effect.

[0057] In addition, it should be understood that when the storage cavity 211 in the drawer 200 is evacuated, the air pressure in the storage cavity 211 is lower than the atmospheric pressure outside the box 100, and the atmospheric pressure can act on the drawer 200 to press the drawer 200 tightly against the box 100, so that the storage cavity 211 of the drawer 200 can be better enclosed in the box 100, and accordingly, it is difficult for the drawer 200 to move relative to the box 100.

[0058] refer to Figures 1 to 4As shown, the refrigerator of the present application further includes a sealing assembly 400, and an air inlet 213 may also be provided on the drawer 200, and the air inlet 213 is communicated with the storage cavity 211. The sealing assembly 400 is provided on the drawer 200, and the sealing assembly 400 is configured to open and close the air inlet 213 of the drawer 200. When the sealing assembly 400 closes the air inlet 213, and the storage cavity 211 is completely located in the cavity 110 of the box 100, it is difficult for the gas outside the box 100 to enter the storage cavity 211. When the sealing assembly 400 opens the air inlet 213, the storage cavity 211 is communicated with the outside of the box 100 through the air inlet 213, so that the air outside the box 100 can enter the storage cavity 211 through the air inlet 213 to increase the air pressure in the storage cavity 211. When the air pressure in the storage cavity 211 increases to a balance with the atmospheric pressure outside the box 100, the atmospheric pressure no longer presses the drawer 200 tightly against the box 100, so that the drawer 200 can move along the bottom wall direction away from the cavity 110, so that at least part of the storage cavity 211 of the drawer 200 can be moved outside the box 100, so that the drawer 200 can be easily opened.

[0059] It should be understood that when the drawer 200 is tightly fitted with the box body 100 under the action of atmospheric pressure for a long time, the contact parts between the drawer 200 and the box body 100 may become sticky, resulting in that even when the air pressure in the storage cavity 211 of the drawer 200 is balanced with the external atmospheric pressure, it is difficult for the drawer 200 to move in a direction away from the bottom wall of the cavity 110 so that at least part of the storage cavity 211 is located outside the box body 100. The user needs to use a large pulling force to pull the drawer 200 out of the box body 100.

[0060] In some embodiments, reference Figure 5 and Figure 6 As shown, the refrigerator of the present application may also be provided with a driving assembly 500, which is provided in the box 100 and connected to the drawer 200. When the storage cavity 211 is located in the box 100 and the air pressure in the storage cavity 211 is not less than the air pressure outside the box 100, the driving assembly 500 is configured to drive the drawer 200 to move relative to the box 100, so that at least part of the storage cavity 211 is located outside the box 100. In this way, the drawer 200 is driven to move by the driving assembly 500, so that the storage cavity 211 in the drawer 200 can be opened more efficiently and conveniently, and the user can save effort.

[0061] Specifically, when the storage cavity 211 of the drawer 200 is completely located in the housing 110 of the shell, and the storage cavity 211 is a negative pressure environment, if the user needs to open the drawer 200, the air inlet 213 of the drawer 200 can be opened through the sealing assembly 400, so that the air outside the box 100 can enter the storage cavity 211 of the drawer 200 until the air pressure inside and outside the storage cavity 211 is balanced. The driving assembly 500 can apply a force to the drawer 200 in the direction opposite to the bottom wall of the housing 110. At this time, even if the drawer 200 and the housing 100 are adhered and difficult to separate, due to the power of the driving assembly 500, the user does not need to apply too much pulling force to the drawer 200, so that the drawer 200 can be moved in the direction away from the bottom wall of the housing 110, so that the storage cavity 211 of the drawer 200 can be easily moved to the outside of the housing 100. As a result, the user can use the refrigerator of the present application more labor-saving and convenient.

[0062] In some embodiments, reference Figure 1 , Figure 5 and Figure 8 As shown, the drawer 200 of the present application can be configured to include a main body 210 and a door 220, wherein the door 220 is connected to the main body 210, and the storage cavity 211 of the drawer 200 is inside the bathroom main body 210. The door 220 is connected to the side of the main body 210 away from the bottom wall of the cavity 110. When the storage cavity 211 is completely located in the cavity 110, the main body 210 is also located in the cavity 110, and the door 220 is blocked at the plug-in interface 120 of the box 100, so that the storage cavity 211 can be enclosed in the box 100.

[0063] There is also a gap space between the door body 220 and the main body 210, so that the installation cavity 230 can be formed between the door body 220 and the main body 210, and at least part of the sealing assembly 400 can be arranged in the installation cavity 230, so that at least part of the sealing assembly 400 can be hidden in the installation cavity 230 between the door body 220 and the main body 210, thereby protecting the sealing assembly 400 and making the structure of the refrigerator of the present application relatively more compact. The air inlet 213 of the drawer 200 is opened in the main body 210 and is located on the side of the main body 210 facing the door body 220, so that the sealing assembly 400 located in the installation cavity 230 can conveniently open and close the air inlet 213.

[0064] In some embodiments, reference Figure 6As shown, in order to enable the driving assembly 500 to drive the drawer 200 to move in the direction away from the bottom wall of the cavity 110, the driving assembly 500 may be configured to include a guide member and a driving member. The guide member is connected to both the box body 100 and the drawer 200, and the guide member is configured to guide and limit the drawer 200 in the moving direction of the drawer 200. Specifically, when the drawer 200 moves toward the bottom wall of the cavity 110 or moves away from the bottom wall of the cavity 110, the guide member can guide and limit the drawer 200, so that the drawer 200 will not deflect when moving toward or away from the bottom wall of the cavity 110, so that the drawer 200 can move smoothly relative to the box body 100. The driving member is also connected to both the box body 100 and the drawer 200. When the storage cavity 211 is located in the box body 100 and the air pressure in the storage cavity 211 is not less than the air pressure outside the box body 100, the driving member is configured to drive the drawer 200 to move relative to the box body 100 so that at least part of the storage cavity 211 is located outside the box body 100. In this way, the drawer 200 is driven to move by the driving member, so that the storage cavity 211 in the drawer 200 can be opened more efficiently and conveniently, and the user can save effort.

[0065] In some embodiments, reference Figure 6 As shown, the guide member of the present application may specifically include a first guide portion 510 and a second guide portion 520. The first guide portion 510 is disposed in the box body 100, and the second guide portion 520 is disposed on the outer side wall of the drawer 200. The first guide portion 510 and the second guide portion 520 are movably connected, and the first guide portion 510 and the second guide portion 520 are guided and matched. Specifically, the first guide portion 510 is disposed on the inner side wall of the cavity 110, and the second guide portion 520 is disposed on the side wall of the main body 210, so that the first guide portion 510 can be opposite to the second guide portion 520, and the first guide portion 510 is extended along the moving direction of the drawer 200, that is, the first guide portion 510 extends along the direction toward or away from the bottom wall of the cavity 110, and the second guide portion 520 is movably embedded in the first guide portion 510, so that the second guide portion 520 can slide along the extension direction of the first guide portion 510. The first guide portion 510 and the second guide portion 520 limit each other so that the second guide portion 520 can only slide along the extension direction of the first guide portion 510, so that the drawer 200 can only move along the extension direction of the first guide portion 510. As a result, the drawer 200 can be limited to move only in the direction toward or away from the bottom wall of the cavity 110, thereby preventing the drawer 200 from getting stuck on the box body 100 during movement.

[0066] In some embodiments, it should be understood that the travel of the second guide portion 520 that can slide relative to the first guide portion 510 is limited by the length of the first guide portion 510, and the travel of the drawer 200 that can move relative to the box body 100 is affected by the travel of the second guide portion 520 and the first guide portion 510 that can move relative to the box body 100. In order to increase the travel of the drawer 200 that can move relative to the box body 100, the refrigerator of the present application may also be provided with a third guide portion, the first guide portion 510 is connected to the second guide portion 520 through the third guide portion, and the third guide portion is movably connected to both the first guide portion 510 and the second guide portion 520. Specifically, the third guide portion cooperates with the first guide portion 510 in the moving direction of the drawer 200, and the third guide portion cooperates with the second guide portion 520 in the moving direction of the drawer 200, so that the total travel of the first guide portion 510 relative to the second guide portion 520 is the sum of the travel of the first guide portion 510 and the third guide portion relative to each other, and the travel of the second guide portion 520 and the third guide portion relative to each other, thereby extending the travel of the first guide portion 510 and the second guide portion 520 relative to each other, and further extending the maximum travel of the drawer 200 relative to the box 100. In this way, the drawer 200 can be more fully withdrawn from the box 100, so that the user can more conveniently take in and put in food from the storage cavity 211 of the drawer 200.

[0067] In some embodiments, in order to enable the driving member of the present application to drive the drawer 200 to move relative to the box 100, the driving member may be an elastic structural member, so that the driving member can be deformed by force and generate elastic force. Among them, one end of the driving member is connected to the drawer 200, and the other end of the driving member can be connected to the box 100. When the storage cavity 211 of the drawer 200 is completely located in the storage cavity 110 of the box 100, and the storage cavity 211 is evacuated by the vacuum assembly 300, the driving member is deformed by force and has an elastic restoring force, and the elastic restoring force of the driving member is less than the difference between the air pressure outside the box 100 and the air pressure in the storage cavity 211 of the drawer 200, so that the elastic restoring force of the driving member will not drive the drawer 200 to move in the direction away from the bottom wall of the storage cavity 110, so that the storage cavity 211 of the drawer 200 can remain in the state of being located in the box 100 as a whole, and then the storage cavity 211 can maintain a vacuum state.

[0068] When the air inlet 213 of the storage cavity 211 of the drawer 200 is opened and the vacuum state of the storage cavity 211 is released, the elastic restoring force of the driving member can drive the drawer 200 to move in a direction away from the opening of the cavity 110, so that the drawer 200 moves to make at least part of the storage cavity 211 outside the box body 100, so that the user can take and put the food in the storage cavity 211.

[0069] The elastic restoring force of the driving member can be set to be relatively large, so that after the air inlet 213 is opened and the air pressure in the storage cavity 211 has not yet completely balanced with the atmospheric pressure outside the box 100, the elastic restoring force of the driving member can drive the drawer 200 to move in a direction away from the bottom wall of the cavity 110, so that the storage cavity 211 in the drawer 200 can be opened more efficiently. In this way, the user does not need to manually pull the drawer 200 to open the storage cavity 211 of the drawer 200, making the refrigerator of the present application more convenient to use.

[0070] In some embodiments, in order to enable the driving member of the present application to drive the drawer 200 to move relative to the box 100, the driving member may also be provided with a locking portion and an elastic portion, wherein the two ends of the elastic portion are connected to the drawer 200 and the box 100 respectively. When the storage cavity 211 of the drawer 200 is located in the box 100, the elastic portion is compressed or stretched and deformed, so that the elastic portion can generate an elastic restoring force. The locking portion is arranged between the box 100 and the drawer 200, and when the storage cavity 211 of the drawer 200 is completely located in the box 100 as a whole, the locking portion is configured to lock or unlock the drawer 200 and the box 100. When the locking portion locks the drawer 200 and the box 100, the drawer 200 cannot move relative to the box 100, and when the locking portion unlocks the drawer 200 and the box 100, the drawer 200 can move relative to the box 100.

[0071] Specifically, when the storage cavity 211 of the drawer 200 is completely located in the box 100 and the storage cavity 211 is evacuated, the locking part can lock the box 100 and the drawer 200, so that no matter how large the elastic restoring force of the elastic part is, the box 100 and the drawer 200 can be locked and fixed by the locking part, thereby preventing the drawer 200 from moving in the second direction under the action of the elastic part. When the air inlet 213 is opened and the vacuum state in the storage cavity 211 is released, the drawer 200 and the box 100 can be unlocked by the locking part, and the drawer 200 can move in the second direction under the action of the elastic restoring force of the elastic part, so that the storage cavity 211 of the drawer 200 can be opened more efficiently.

[0072] In some embodiments, when the drawer 200 in the present application moves along the first direction until at least part of the storage cavity 211 is located in the box 100, the locking part is configured to lock or unlock the drawer 200 and the box 100 in the second direction. Specifically, when the storage cavity 211 of the drawer 200 of the present application needs to be converted from an open state to a vacuum state, the user can push the door 220 of the drawer 200 to move the drawer 200 in the first direction. When the drawer 200 moves to at least part of the storage cavity 211 is located in the box 100, the locking part can lock the drawer 200 in the second direction, so that the drawer 200 cannot move in the second direction, thereby making the drawer 200 reach a pre-locked state. At this time, the drawer 200 can only move in the first direction, and the vacuum assembly 300 can start to evacuate the storage cavity 211 of the drawer 200, and the vacuum assembly 300 evacuates the storage cavity 211 at a rate greater than the speed at which the gas outside the shell enters the storage cavity 211. In this way, the drawer 200 can be pushed to move in the first direction under the action of atmospheric pressure until the storage cavity 211 is completely located in the box 100. The vacuum assembly 300 can continue to evacuate the drawer 200 to further tightly connect the drawer 200 with the box 100. In this way, the efficiency of the refrigerator of the present application being converted into a vacuum state can be improved.

[0073] When it is necessary to release the vacuum state of the storage cavity 211 and open the storage cavity 211 from the box body 100, the drawer 200 can be unlocked in the second direction through the locking part, so that the drawer 200 can be moved more efficiently along the second direction under the action of the elastic restoring force of the elastic part, so that the storage cavity 211 of the drawer 200 can be opened more efficiently.

[0074] In some embodiments, reference Figure 6 As shown, the first guide portion 510, the second guide portion 520 and the third guide portion of the present application can all adopt a guide rail structure. Accordingly, the drive assembly 500 of the present application can adopt a push-open guide rail, and the push-open guide rail is in the unlocked state as an example for explanation. Press the push-open guide rail once, and the push-open locking structure is converted from the unlocked state to the locked state; press the push-open guide rail again, and the push-open guide rail is converted from the locked state to the unlocked state. That is, by pressing the push-open guide rail once, the push-open locking structure switches between the locked state and the unlocked state, making the operation of the refrigerator of the present application simpler and more convenient.

[0075] In some embodiments, reference Figure 5 and Figure 7 As shown, the number of the driving components 500 of the present application can be set to two, and the two driving components 500 can be respectively arranged on the two side walls of the main body 210 of the drawer 200, and connected to the two side walls of the cavity 110 of the box body 100, so that the drawer 200 is more balanced and stable when moving relative to the box body 100.

[0076] In some embodiments, reference Figures 8 to 12 As shown, the sealing assembly 400 of the present application may include a base 410, a pressing member 420 and a sealing member 430. The base 410 is arranged on the drawer 200, and the pressing member 420 is movably arranged on the base 410, so that the pressing member 420 can move relative to the base 410. The pressing member 420 is connected to the sealing member 430. When the pressing member 420 moves relative to the base 410, the pressing member 420 can drive the sealing member 430 to open and close the air inlet 213. Since the pressing member 420 is connected to the sealing member 430, the sealing member 430 can be indirectly arranged on the base 410 through the pressing member 420, so that the pressing member 420 and the sealing member 430 can be directly or indirectly assembled on the base 410, so that the modularization degree of the sealing assembly 400 is higher. Therefore, when assembling the refrigerator of the present application on an assembly line, the pressing member 420 and the sealing member 430 can be assembled on the base 410 to form the sealing assembly 400, and then the sealing assembly 400 can be assembled on the drawer 200. This can avoid transferring the drawer 200 to multiple workstations, thereby improving the assembly efficiency of the refrigerator of the present application.

[0077] In addition, when the sealing assembly 400 fails, the base 410 can be removed from the drawer 200 and a new sealing assembly 400 can be installed on the drawer 200, thereby improving the maintenance efficiency of the refrigerator of the present application.

[0078] In some embodiments, reference Figures 8 to 12 As shown, the base 410 of the sealing assembly 400 can be set on the main body 210 and located on the side of the main body 210 facing the door body 220, so that the sealing assembly 400 as a whole can be close to the air inlet 213 on the main body 210, so that the sealing assembly 400 can open and close the air inlet 213 more conveniently.

[0079] In addition, the main body 210 is the main structure of the drawer 200. Accordingly, the main body 210 has relatively better structural strength. Setting the base 410 on the main body 210 can make the sealing assembly 400 relatively more stable when installed on the drawer 200.

[0080] In some embodiments, reference Figures 8 to 12 As shown, in order to allow the base 410 to be fixedly mounted on the main body 210, a mounting groove 214 may be provided on one side of the main body 210 facing the door body 220, and the base 410 may be embedded in the mounting groove 214. Specifically, the groove shape of the mounting groove 214 of the main body 210 matches the shape of the base 410, so that when the base 410 is embedded in the mounting groove 214, the base 410 and the outer wall may abut against the inner wall of the mounting groove 214, so that the base 410 can be clamped in the mounting groove 214, so that the base 410 can be reliably connected to the main body 210.

[0081] When installing the base 410, the base 410 can be squeezed into the mounting groove 214, which makes it easy to install the base 410. When the base 410 needs to be removed, the base 410 can be removed from the mounting groove 214 by tools such as a knock rod, which makes it easy to remove the base 410.

[0082] In addition, in other embodiments, the base 410 and the mounting groove 214 may also have corresponding fixing hole structures, such as screw holes, and the base 410 and the mounting groove 214 may be fixed by bolts, so that the base 410 can be more reliably connected to the main body 210.

[0083] In some embodiments, reference Figures 8 to 12 As shown, in order to facilitate the user to operate the sealing assembly 400 to open and close the air inlet 213, the door body 220 is provided with a movable groove 221 that runs through the door body 220, and the movable groove 221 is extended along the first direction, that is, the direction from one notch to another notch of the movable groove 221 is the first direction or the second direction. The pressing member 420 is configured to be movable along the first direction or the second direction, wherein when the pressing member 420 moves along the first direction, the pressing member 420 can drive the sealing member 430 to open the air inlet 213, so that the sealing member 430 is separated from the air inlet 213. When the pressing member 420 moves along the second direction, the pressing member 420 can drive the sealing member 430 to move toward the air inlet 213, so that the sealing member 430 can close the air inlet 213, so that the sealing member 430 is blocked at the air inlet 213.

[0084] Specifically, when a user operates the refrigerator of the present application, the user can be in a position opposite to the door body 220 of the drawer 200 and apply force to the pressing member 420 to press the pressing member 420, so that the sealing member 430 can be separated from the air inlet 213, thereby contacting the storage cavity 211 of the drawer 200 to a vacuum state. This makes the refrigerator of the present application easier to operate and more ergonomic to use.

[0085] In some embodiments, reference Figures 8 to 12As shown, in order to enable the pressing member 420 to drive the sealing member 430 to disengage from the air inlet 213 when moving along the first direction, the sealing assembly 400 of the present application may also be provided with a first connecting rod 440, the first connecting rod 440 having a first end 441, a second end 442 and a third end 443, the first end 441 and the second end 442 of the first connecting rod 440 are located at both ends of the first connecting rod 440, and the first end 441 and the second end 442 constitute the two ends of the first connecting rod 440. The third end 443 of the first connecting rod 440 is located between the first end 441 and the second end 442, and the third end 443 is rotatably connected to the base, so that the first connecting rod 440 as a whole can be rotatably connected to the base. The first end 441 of the first connecting rod 440 is movably connected to the pressing member 420, and the second end 442 of the first connecting rod 440 is connected to the sealing member 430. The first connecting rod 440 can constitute a lever structure. When the first connecting rod 440 rotates, the first end 441 and the second end 442 of the first connecting rod 440 move in different directions.

[0086] When the pressing member 420 moves in the first direction, the pressing member 420 is movably connected to the first end 441 of the first connecting rod 440, so that the pressing member 420 can push the first end 441 of the first connecting rod 440 to rotate in the clockwise direction, thereby driving the second end 442 of the first connecting rod 440 to rotate, so that the second end 442 can be displaced in the second direction as a whole. As a result, the sealing member 430 connected to the second end 442 can be displaced in the second direction, so that the sealing member 430 moves away from the air inlet 213 and is separated from the air inlet 213, so that the sealing member 430 opens the air inlet 213.

[0087] When the pressing member 420 moves in the second direction, the pressing member 420 is movably connected to the first end 441 of the first connecting rod 440, so that the pressing member 420 pulls the first end 441 of the first connecting rod 440 to rotate in the counterclockwise direction, thereby driving the second end 442 of the first connecting rod 440 to rotate, so that the second end 442 can generate displacement in the first direction as a whole. As a result, the sealing member 430 connected to the second end 442 can generate displacement in the first direction, so that the sealing member 430 moves toward the air inlet 213 and blocks the air inlet 213, so that the sealing member 430 closes the air inlet 213.

[0088] In some embodiments, reference Figures 8 to 12As shown, the sealing assembly 400 of the present application may also be provided with a second connecting rod 450, one end of which is connected to the main body 210, and the other end of the second connecting rod 450 is connected to the third end 443 of the first connecting rod 440. Thus, the first connecting rod 440 is rotatably connected to the main body 210 through the second connecting rod 450. Specifically, one end of the second connecting rod 450 connected to the first connecting rod 440 extends in a direction away from the main body 210, so that the first connecting rod 440 can maintain a certain distance from the main body 210, so that there is enough space between the first connecting rod 440 and the main body 210 for the first connecting rod 440 to rotate, so that the first connecting rod 440 has a larger rotation range, avoiding the first connecting rod 440 and the main body 210 from interfering with each other.

[0089] The first connecting rod 440 and the second connecting rod 450 may be an integral structure and prepared by an integral molding process, so that the connection reliability between the first connecting rod 440 and the second connecting rod 450 is better, thereby improving the reliability of the sealing assembly 400.

[0090] In some embodiments, reference Figures 8 to 12 As shown, the length from the first end 441 to the third end 443 of the first connecting rod 440 is greater than the length from the second end 442 to the third end 443 of the first connecting rod 440, so that the first connecting rod 440 can form a labor-saving lever structure. Specifically, the length from the first end 441 to the third end 443 is longer, so that the length of the force arm from the first end 441 to the third section is longer, thereby, the pressing member 420 applies a smaller force along the first direction to the first end 441, so that the sealing member 430 is subjected to a larger force along the second direction, so that the sealing member 430 is more easily separated from the air inlet 213. In this way, when the user uses the refrigerator of the present application, the storage cavity 211 of the drawer 200 can be released from the vacuum state by applying a smaller pressing force to the pressing member 420, making the operation of the refrigerator of the present application more labor-saving and convenient.

[0091] In some embodiments, reference Figures 8 to 12 As shown, in order to make the pressing member 420 of the present application more convenient to move along the second direction so that the sealing member 430 moves toward the air inlet 213 to block the air inlet 213, the sealing assembly 400 of the present application may also be provided with an elastic member 460, one end of which is connected to the base 410, and the other end of which is connected to the pressing member 420. When the pressing member 420 moves along the first direction, the elastic member 460 is deformed by force to generate an elastic restoring force, and the elastic restoring force of the elastic member 460 can drive the pressing member 420 to move along the second direction, so that the sealing member 430 moves along the first direction to block the air inlet 213.

[0092] Specifically, when the user no longer applies pressing force in the first direction to the pressing member 420 , the elastic member 460 can drive the pressing member 420 to move in the second direction under the action of the elastic restoring force, thereby causing the first end 441 of the first connecting rod 440 to rotate counterclockwise, thereby causing the sealing member 430 to move toward the air inlet 213 .

[0093] In some embodiments, reference Figure 13 to Figure 14 As shown, the sealing member 430 of the present application has a sealing surface 431. When the sealing member 430 blocks the air inlet 213 and closes the air inlet 213, the sealing surface 431 of the sealing member 430 covers the air inlet 213, and the positive projection of the air inlet 213 on the sealing surface 431 is located inside the sealing surface 431, and the axis of the air inlet 213 is perpendicular to the sealing surface 431. Thus, the sealing surface 431 can be directly opposite to the air inlet 213, so that the part where the sealing surface 431 fits with the main body 210 can be tightly connected with the main body 210, avoiding the gap between the sealing surface 431 and the main body 210, and ensuring the sealing effect of the sealing member 430 on the air inlet 213. At the same time, the situation that the sealing member 430 is squeezed and deformed by the inner wall of the air inlet 213 is avoided, so that the durability and reliability of the sealing member 430 are better.

[0094] Specifically, the area of ​​the sealing surface 431 is larger than the opening area of ​​the air inlet 213, so that part of the sealing surface 431 can fit with the part of the main body 210 close to the air inlet 213, so that the sealing surface 431 can completely cover the air inlet 213. The contact area between the sealing surface 431 of the sealing member 430 and the main body 210 is also relatively larger, so that the sealing member 430 can better block and close the air inlet 213. In addition, the sealing surface 431 can be located outside the air inlet 213 as a whole, which can prevent the sealing surface 431 from extending into the air inlet 213 and causing the sealing member 430 to produce plastic deformation, so that the sealing member 430 can still have a good sealing effect after long-term use.

[0095] In some embodiments, reference Figure 13 to Figure 14 As shown, the sealing member 430 of the present application may include a first sealing portion 432 and a second sealing portion 433, a sealing surface 431 is provided on the first sealing portion 432, and a second sealing portion 433 is provided on the sealing surface 431, and an orthographic projection of the second sealing portion 433 on the sealing surface 431 is located inside the sealing surface 431, and when the sealing surface 431 closes the air inlet 213, the second sealing portion 433 is located inside the air inlet 213. Specifically, the size of the second sealing portion 433 may match the size of the air inlet 213, so that when the second sealing portion 433 extends into the air inlet 213, the outer wall of the second sealing portion 433 may fit closely with the inner wall of the air inlet 213, which may further enhance the reliability of the sealing member 430 of the present application in closing the air inlet 213.

[0096] In some embodiments, reference Figure 13 to Figure 14 As shown, the inner diameter of the second sealing portion 433 gradually decreases in the direction away from the sealing surface 431. Specifically, the second sealing portion 433 can adopt a truncated cone structure, and the side surface of the second sealing portion 433 is an arc surface and inclined. The side wall of the second sealing portion 433 can play a role in guiding the second sealing portion 433 to be inserted into the air inlet 213, so that the second sealing portion 433 is easier to insert into the air inlet 213, thereby making it easier for the sealing assembly 400 of the present application to block and close the air inlet 213.
