Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a refrigerator. Background Art

[0002] In recent years, people's health awareness has gradually increased, and the demand for food preservation has also increased accordingly. As the most commonly used household appliance for food storage, food preservation and storage has become a technical demand that needs to be urgently addressed in the refrigerator field.

[0003] At present, various manufacturers have introduced different preservation technologies to address the issue of food preservation and storage. For example, vacuum preservation technology changes the conditions for food spoilage under vacuum conditions. First, in a vacuum environment, it is difficult for microorganisms and various enzymes to survive, and it takes a long time to meet the requirements for microbial growth; secondly, in a vacuum state, the oxygen in the container is greatly reduced, various chemical reactions cannot be completed, and food will not be oxidized, which also allows food to be kept fresh for a long time.

[0004] The vacuum preservation technology currently used in refrigerators mainly involves setting up sealed drawers in the refrigerator, and using a small vacuum pump installed outside the drawer to evacuate the drawer, so that the drawer maintains a negative pressure state, thereby preserving the food in the drawer. This preservation method has the following limitations: 1. Since the vacuum treatment needs to be achieved through a vacuum pump, the vacuum pump will occupy part of the storage space in the refrigerated compartment; 2. This preservation method requires the drawer to be sealed, otherwise a vacuum state cannot be formed in the drawer, so it places high demands on the molding and assembly process of the drawer; 3. This preservation method can only preserve the food in the drawer, but cannot preserve the food in other areas of the refrigerator. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the preservation effect of existing refrigerators is not ideal, and thus a refrigerator with low cost, no storage space occupation and the ability to preserve food in all areas is proposed.

[0006] To solve the above technical problems, the present invention discloses a refrigerator, which includes a storage compartment and a door body for opening or closing the storage compartment. A vacuum packaging device is provided on the door body. The vacuum packaging device includes an evacuation area and a packaging area arranged from inside to outside. The open ends of the storage bags are respectively inserted into the evacuation area and the packaging area. The evacuation area evacuates the storage bags, and the packaging area is used for plastic-sealing the storage bags; an evacuation assembly for evacuating the evacuation area, and the evacuation assembly is mounted on a mounting seat; the evacuation assembly includes: a vacuum pump, and the vacuum pump is communicated with the evacuation area through a pipeline; the vacuum pump includes a square pump body part and a cylindrical motor part; a vibration isolation member is arranged between the vacuum pump and the mounting seat, and the vibration isolation member includes a first vibration isolation sleeve sleeved on the pump body part and / or a second vibration isolation sleeve sleeved on the motor part.

[0007] The technical solution of the present invention has the following technical effects compared with the prior art:

[0008] The refrigerator of the present invention is provided with a vacuum packaging device on the door body, which can perform vacuum packaging treatment on the storage bags containing food ingredients to be put into the refrigerator; compared with the existing vacuum drawers, the vacuum packaging device of the present invention can perform vacuum fresh-keeping treatment on the food ingredients stored in various compartments of the refrigerator, expanding the fresh-keeping range; in addition, a vibration isolation member is arranged between the vacuum pump in the evacuation assembly of the vacuum packaging device and the mounting seat, which can reduce the noise and vibration during the operation of the vacuum packaging device, and the user experience is good.

[0053] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0054] Embodiment 1

[0055] Figure 1 This is a perspective view of a specific implementation manner of the refrigerator of the present invention; referring to Figure 1 , the refrigerator 1 of this embodiment has an approximate rectangular parallelepiped shape. The appearance of the refrigerator 1 is defined by a storage compartment 100 that defines a storage space and a plurality of door bodies 200 provided in the storage compartment 100, wherein, referring to Figure 2, the door body 200 includes a door body housing 210 located outside the storage chamber 100, a door body inner liner 220 located inside the storage chamber 100, an upper end cover 230, a lower end cover 240, and a heat insulation layer located between the door body housing 210, the door body inner liner 220, the upper end cover 230, and the lower end cover 240; usually, the heat insulation layer is filled with foaming material.

[0056] The storage chamber 100 is an open box, and the storage chamber 100 is vertically partitioned into a lower freezer compartment A and an upper refrigerating compartment 100B. Each of the separated spaces can have an independent storage space. Specifically, the freezer compartment 100A is located at the lower side of the storage chamber 100 and can be selectively covered by a drawer-type freezer door A. The space above the freezer compartment 100A is partitioned into left and right sides to form the refrigerating compartment 100B respectively, and the refrigerating compartment 100B can be selectively opened or closed by a refrigerating compartment door body 200B pivotally mounted on the refrigerating compartment 100B.

[0057] As Figure 3 , Figure 4 As shown, a vacuum packaging device 300 is provided on the door body 200 of the refrigerator. The vacuum packaging device 300 is used to evacuate and seal a storage bag; the vacuum packaging device 300 can be provided on the freezer door body 200A or on the refrigerating compartment door body 200B. Since the refrigerating compartment door body 200B is located on the upper side, in order to conform to the user's usage habit, it is usually preferably provided on the refrigerating compartment door body 200B.

[0058] As Figures 4 - 1 Figure 7 shows an embodiment of the vacuum packaging device 300. In this embodiment, as Figure 4 shown, the vacuum packaging device 300 includes: a lower support 310 provided with a first open cavity 311; an upper support 320 provided with a second open cavity 321. The upper support 320 can move in a direction approaching or away from the lower support 310 under the drive of a drive device 340. After the upper support 320 moves in place in the direction approaching the lower support 310, the first open cavity 311 and the second open cavity 321 are docked and sealed to form a vacuum extraction area 301. The above-mentioned vacuum packaging device 300 realizes the locking and unlocking of the lower support 310 and the upper support 320 by controlling the automatic lifting of the drive device 340, realizes automatic vacuum packaging, and improves the intelligent level of the refrigerator.

[0059] Specifically, in order to improve the sealing performance of the vacuum extraction area 301, as Figure 4As shown, a sealing portion for sealing the evacuated area 301 is provided on the opposing surfaces of the lower support 310 and the upper support 320. Specifically, the lower support 310 is provided with a first sealing groove 313 on the outer periphery of the first open cavity 311, and the upper support 320 is provided with a second sealing groove 323 on the outer periphery of the second open cavity 321. The positions of the first sealing groove 313 and the second sealing groove 323 are opposite to each other and a sealing ring 350 is provided inside. The two sealing rings 350 provided in the first sealing groove 313 and the second sealing groove 323 seal the evacuated area 301 inside, achieving reliable sealing of the evacuated area 301.

[0060] Specifically, as Figure 5 shown, a limiting portion is provided in the first open cavity 311 or the second open cavity 321 for limiting the insertion position of the storage bag inserted into the evacuated area 301 to prevent the opening position of the storage bag from extending out of the evacuated area 301; specifically, the limiting portion is a limiting rib 322 provided in the first open cavity 311 or the second open cavity 321, and the height of the limiting rib 322 is greater than the depth of the first open cavity 311 or the second open cavity 321; the length of the limiting rib 322 is slightly lower than the length of the first open cavity 311 or the second open cavity 321. When the user inserts the storage bag into the evacuated area 301, the limiting rib 322 can block the storage bag from continuing to be inserted inward; in other embodiments, a position detection device can also be provided in the evacuated area 301. Specifically, a microwave sensor or an infrared sensor can be used to detect the presence or absence of the storage bag inserted into the evacuated area 301, and then send a signal indicating whether the storage bag is in place to the controller. The controller can control the opening of the vacuum pump according to the in-place signal. By providing a position detection device, it can automatically detect whether the storage bag is in place, and the controller can then automatically control the on / off of the vacuum pump.

[0061] The vacuum packaging device 300 further includes a vacuum pumping assembly 330, as Figure 6 、 Figure 7As shown, the vacuum pumping assembly 330 includes a vacuum pump 331 communicated with the vacuum pumping area 301 through a pipeline 335; a pressure detection device 332 and a gas balancing device 333 are further arranged on the pipeline 335. Among them, the pressure detection device 332 is specifically a pressure sensor for detecting the pressure in the vacuum pumping area 301; the gas balancing device 333 is specifically an electric balancing valve. When the electric balancing valve is opened, the gas in the vacuum pumping area 301 is communicated with the external gas. When the user performs vacuum packaging, the vacuum pump 331 is turned on to perform vacuum pumping on the vacuum pumping area 301. When the pressure detection device 332 detects that the pressure in the vacuum pumping area 301 reaches the set negative pressure value, the controller controls the vacuum pump 331 to stop. By setting the pressure sensor, the vacuum degree of the vacuum pumping area 301 can be controlled, and the vacuum pump 331 can be turned on and off according to the detection value of the pressure sensor, ensuring the vacuum pumping effect. After the vacuum pumping and packaging operations are completed, by opening the above-mentioned electric balancing valve, the vacuum pumping area 301 can be communicated with the external gas, and the air pressure increases to the standard atmospheric pressure, which is convenient for the user to take out the storage bag.

[0062] To prevent foreign objects in the vacuum pumping area 301 from entering the vacuum pump 331 through the pipeline 335, a filtering and protecting device is further arranged on the pipeline 335. In one implementation, as Figure 8 shown, the filtering and protecting device is specifically a filtering container 334 connected in series on the pipeline 335. The upper end of the filtering container 334 is provided with an inlet and an outlet. The inlet is communicated with the vacuum pumping area 301 through a pipeline, and the outlet is communicated with the vacuum pump 331 through a pipeline; foreign objects in the vacuum pumping area 301 enter the filtering container 334 through the pipeline 335 and are retained at the bottom of the filtering container 334, preventing foreign objects from entering the vacuum pump 331. To facilitate the cleaning of the filtering container 334, more specifically, the filtering container 334 includes a tank body with an opening and an upper cover detachably connected to the tank body. The inlet and the outlet are arranged on the upper cover. During cleaning, the tank body can be removed for cleaning, avoiding the problem that the sealing performance of the pipeline 335 deteriorates due to frequent disassembly and assembly of the pipeline 335.

[0063] In another implementation, as Figure 9 shown, the filtering and protecting device is a filter screen 336 arranged on the pipeline 335. Specifically, for the convenience of disassembly and assembly, the filter screen 336 is arranged at the vent hole 324 at the connection position between the upper support 320 and the pipeline 335. After the user moves the upper support 320 to the highest position, the filter screen 336 can be disassembled, assembled or cleaned from the lower side.

[0064] The connection hole between the vacuum extraction area 301 and the pipeline 335 can be one. Of course, in order to avoid the connection hole in the vacuum extraction area 301 being blocked by foreign objects, resulting in a vacuum extraction failure, it is also possible to connect the pipeline 335 through two or more connection holes. The pipelines 335 are arranged in parallel and connected to the main pipeline through a three-way or multi-way connector; the pressure sensor and the electronic balance valve are arranged on the main pipeline.

[0065] When the vacuum pump operates, it will generate relatively large vibration noise, bringing a poor user experience. Since the noise generated by the operation of the vacuum pump 331 is mainly caused by the vibration of the vacuum pump 331 hitting the outer mounting seat 305, to solve this problem, as Figure 6 、 Figure 7 shown, a vibration isolation member is provided between the vacuum pump 331 and the mounting seat 305.

[0066] Specifically, as Figure 10 shown, the vacuum pump 331 includes a square pump body part 331A and a cylindrical motor part 331B; the vibration isolation member includes a first vibration isolation sleeve 337 sleeved on the pump body part 331A and / or a second vibration isolation sleeve 338 sleeved on the motor part 331B. Among them, the first vibration isolation sleeve 337 and the second vibration isolation sleeve 338 are made of silica gel material. Silica gel has good damping characteristics and can reduce the transmission of vibration. The first vibration isolation sleeve 337 and the second vibration isolation sleeve 338 are sleeved on the vacuum pump 331 and then clamped in the mounting seat 305. The silica gel vibration isolation sleeve can reduce the transmission of the vibration of the vacuum pump 331 to the mounting seat 305, thereby reducing the vibration noise.

[0067] As Figure 11 shown, the first vibration isolation sleeve 337 includes a first body 3371 and several outer vibration isolation protrusions 3372 protruding from the outside of the first body 3371. Several symmetrically arranged and penetrating through holes are formed on the outer vibration isolation protrusions 3372, and the outer end surface of the outer vibration isolation protrusions 3372 contacts the mounting seat 305.

[0068] More specifically, the first body 3371 is an open square sleeve structure with 5 faces, which is sleeved on the outer peripheral surface and bottom surface of the lower pump body part 331A of the vacuum pump 331. The outer vibration isolation protrusions 3372 are circular, and four symmetrically arranged through holes are provided thereon, so that the outer surface of the outer vibration isolation protrusions 3372 is in a cross-shaped rib shape, which is used to reduce the stiffness of the protrusions and improve the vibration damping performance.

[0069] The first vibration isolation sleeve 337 further includes a plurality of inner vibration isolation protrusions 3373 protruding from the inner side of the first body 3371. A plurality of symmetrically arranged hollow holes penetrating the inside and outside of the first body 3371 are formed on the inner vibration isolation protrusions 3373. The inner vibration isolation protrusions 3373 and the outer vibration isolation protrusions 3372 are symmetrically arranged inside and outside, and the inner vibration isolation protrusions 3373 are in contact with the vacuum pump 331. The inner vibration isolation protrusions 3373 are used to reduce the transmission of the vibration of the vacuum pump 331 to the first vibration isolation sleeve 337; the outer vibration isolation protrusions 3372 are used to reduce the transmission of the vibration of the first vibration isolation sleeve 337 to the mounting seat 305. By providing two vibration isolation protrusions inside and outside, the vibration isolation performance is further improved.

[0070] Specifically, the second vibration isolation sleeve 338 includes a second body 3381 and a second vibration isolation protrusion 3382 surrounding the outside of the second body 3381. A plurality of hollow holes are formed in the second vibration isolation protrusion 3382 along the axial direction of the second vibration isolation sleeve 338. The outer end surface of the second vibration isolation protrusion 3382 is in contact with the mounting seat 305. Specifically, the structure of the second body 3381 is not unique. In one way, the second body 3381 is sleeved on the outer circumference of the motor part 331B; in this way, there is no positioning in the axial direction of the motor, and the second body 3381 can be axially displaced; therefore, preferably, as Figure 12A 、 Figure 12B shown, the second body 3381 includes a cylindrical sleeve body and a top wall. A through hole 3383 suitable for the motor shaft to pass through and a wire harness hole 3384 suitable for the wire harness to pass through are provided on the top wall. The second vibration isolation sleeve 338 is sleeved on the outer peripheral surface and the upper end surface of the motor part 331B.

[0071] By providing the first vibration isolation sleeve 337 and the second vibration isolation sleeve 338, vibration isolation treatment can be respectively carried out on the two side ends with larger vibration during the operation of the vacuum pump 331, greatly reducing the vibration noise of the vacuum packaging device.

[0072] As Figure 4As shown, the vacuum packaging device 300 further includes a packaging area 302 located outside the evacuation area 301. The packaging area 302 is used to perform plastic sealing on the storage bag after the evacuation is completed. An insulating pad 360 and a heating device 370 are oppositely arranged in the packaging area 302. Specifically, the heating device 370 is installed in a groove on the lower surface of the upper support 320. The insulating pad 360 is installed in a groove on the upper surface of the lower support 310 of the upper support 320. When the upper support 320 moves to form a sealed evacuation area 301 with the lower support 310, the insulating pad 360 in the packaging area 302 abuts against the heating device 370. After the evacuation is completed, the heating device 370 in the packaging area 302 can quickly plastic-seal the storage bag. After setting the working duration of the heating device 370, the driving device 340 is controlled to drive the upper support 320 to move upward, and the user can take out the storage bag to complete the plastic sealing of the storage bag.

[0073] More specifically, as Figure 13 , Figure 14 shown, the heating device 370 includes a heating wire 371. A heat conduction plate 373 is arranged below the heating wire 371, which is used to spread the heating area of the heating wire 371 to increase the plastic-sealing area of the storage bag and make the plastic sealing firm. The heating wire 371 extends along the length direction of the upper support 320 and bends upward on both sides of the upper support 320. The free ends of the heating wire 371 extending to the upper side of the upper support 320 are fixed to the upper support 320 through an insulating plate 372. Specifically, the insulating plate 372 is made of insulating material and is formed into a bent plate, covering the outside of the heating wire 371 to prevent the heating wire 371 from being exposed outside. Further, the two free ends of the heating wire 371 are respectively connected to two wires led out through a wiring terminal 374 by springs 375. By setting the springs 375, the heating wire 371 can always be in a tensioned state, making the heating wire 371 have a high flatness, and the heat conduction plate 373 located below the heating wire 371 is in close contact with the storage bag, avoiding the problem that the plastic sealing cannot be performed due to the unevenness of the heating wire 371 resulting in non-solid contact at individual positions.

[0074] In the above vacuum packaging device, the driving device 340 can be an electric driving device or a pneumatic driving device. The pneumatic driving device occupies a large space. Therefore, in this embodiment, the driving device 340 adopts an electric driving device. Specifically, as Figure 7 , Figure 15 and Figure 16As shown, the driving device 340 includes a motor 341 and a transmission mechanism. The transmission mechanism is used to convert the rotational motion of the motor into a linear motion, and the output end of the transmission mechanism is connected to the upper support. The transmission mechanism includes a first gear 342 fixedly connected to the output shaft of the motor; a second gear 343 meshing with the first gear 342; a third gear 344 fixedly connected to the second gear 343, and an output rack 345 meshing with the third gear 344. Wherein, a pin hole is provided on the lower side of the output rack 345, and the upper support 320 is connected to the output rack 345 through a pin shaft 346 inserted into the pin hole. Through the above transmission mechanism, the rotation of the motor 341 is converted into the up and down movement of the upper support 320.

[0075] Specifically, as Figure 7 shown, a connecting plate 347 is provided between the upper support 320 and the driving device 340. The connecting plate 347 is threadedly connected to the upper support 320, and a guiding groove 3471 is formed on the connecting plate 347. The lower end of the output rack 345 is inserted into the guiding groove 3471. Long-strip-shaped pin holes are respectively provided on the guiding groove 3471 and the lower end of the output rack 345. The pin shaft 346 passes through the pin holes of the guiding groove 3471 and the output rack 345. There is a gap between the lower end surface of the output rack 345 and the bottom of the guiding groove 3471, and an elastic body 348 is provided in the gap.

[0076] As Figure 15 shown, at the initial position, the upper support 320 is located at the highest position; in the pressing stage, as Figure 16 shown, the driving device 340 drives the upper support 320 to move downward. In order to ensure the tight fit between the lower support 310 and the upper support 320, usually the set rotation stroke of the motor 341 is used as the in-place judgment signal. Therefore, setting the elastic body 348 between the output rack 345 and the guiding groove 3471 can enable the output rack 345 to continue to move downward for a certain distance after the upper support 320 moves downward to contact the lower support 310, so that the elastic body 348 is compressed, preventing the motor 341 from stalling, playing a protective role for the motor 341, and enabling the pressing force to remain stable.

[0077] In the vacuum pumping stage, a sealed vacuum pumping area 301 is formed between the lower support 310 and the upper support 320. Due to the decrease in air pressure, under the action of atmospheric pressure, the upper support 320 moves downward. At this time, due to the existence of the long-strip-shaped pin hole, the output rack 345 can remain stationary when the upper support 320 moves downward, playing a protective role for the entire driving device 340.

[0078] In order to precisely control the moving displacement of the upper support 320 and then determine whether the upper support 320 has moved in place to form a sealed space in the vacuum pumping area 301; in one implementation, the motor 341 is a stepper motor 341, and it is determined whether the upper support 320 has moved in place by detecting the rotation stroke of the stepper motor 341. In another implementation, a microswitch is provided on the lower support 310 or the upper support 320; after the upper support 320 moves in place, the microswitch is triggered, and the controller controls the driving device 340 to stop and lock at the current position according to the feedback signal of the microswitch.

[0079] The driving device 340 can be set to one, and the output gear is located in the middle area of the upper support 320. This situation easily causes the edge area of the upper support 320 to fit less tightly with the lower support 310, resulting in air leakage in the vacuum pumping area 301; therefore, in order to provide the sealing performance of the vacuum pumping area 301, the driving devices 340 are respectively arranged on both sides of the upper support 320. Correspondingly, one connecting plate 347 is provided, and two guiding grooves 3471 are provided on the connecting plate 347; two output racks 345 respectively extend into the guiding grooves 3471.

[0080] Specifically, as Figure 6 、 Figure 7 shown, the driving device 340 and the vacuum pumping assembly 330 are both installed on the mounting seat 305 located on the upper side of the upper support 320. An air vent hole 324 is provided on the upper support 320 for communicating with the vacuum pumping assembly 330. Among them, one side of the mounting seat 305 is provided with three chambers, including a vacuum pump mounting chamber 3051 located in the middle position and driving device mounting chambers 3052 located on the left and right sides. In order to maintain the overall aesthetic appearance of the outer surface of the refrigerator door body 200 and the convenience of applying the vacuum packaging device 300, as Figure 3 shown, the door body housing 210 is provided with an inwardly recessed mounting chamber 211. After the driving device 340 is connected to the upper support 320, it is connected to the mounting seat 305 by screws. After the vacuum pumping assembly 330 is connected to the air vent hole 324 on the upper support 320 and installed on the mounting seat 305, after forming a component, the side of the mounting seat 305 with the chambers faces the door body housing 210, and the whole is installed in the mounting chamber 211 by screws passing through the lugs on both sides of the mounting seat 305. Each component realizes modular assembly, and each part is not exposed on the outer surface, and the integrity of the device is better.

[0081] When the user applies the vacuum packaging device 300 to seal a food bag, especially when sealing foods with a powdery texture such as flour or liquids, etc., during the vacuum pumping process, the powder or liquid may enter the vacuum pumping area 301 and eventually accumulate in the first open cavity 311 of the lower support 310. Therefore, in order to facilitate the user to clean the food residues in the lower support 310, the lower support 310 is detachably installed relative to the door body 200.

[0082] Among them, the method of installing the lower support 310 on the door body 200 is not unique. In this embodiment, as Figures 17A - 17C shown, the lower support 310 can be detachably installed on the door body 200 from the inner side of the door body 200 (i.e., the side with the inner liner). Since the door body 200 of the refrigerator must ensure heat insulation, therefore, a heat preservation small door 250 is provided on the inner side part of the lower support 310 facing the storage chamber 100. Among them, as Figure 17C shown, an installation hole 201 communicating inside and outside is opened on the door body 200, and the lower support 310 and the heat preservation small door 250 are inserted into the installation hole 201 from the inner side of the door body 200, realizing the disassembly and cleaning of the lower support 310 and the heat preservation performance of the door body 200 at the same time.

[0083] In one implementation manner, as Figure 18 shown, the lower support 310 and the heat preservation small door 250 are integrally formed; as Figure 19 、 Figure 20 shown, the lower support 310 and the heat preservation small door 250 are formed by a first shell 251 and a second shell 252 with an open cavity structure and a heat insulation member arranged between the first shell 251 and the second shell 252. Among them, the first shell 251 and the second shell 252 are snap-connected. The first shell 251 is provided with an extension arm 2511 in the direction away from the second shell 252, and the lower support 310 is formed on the extension arm 2511. The first open cavity 311 is an opening groove formed on the upper side of the extension arm 2511, and a first sealing groove 313 is provided on the outer periphery of the opening groove.

[0084] In order to further ensure the heat insulation of the door body 200 and avoid cold leakage through the gap between the installation hole 201 and the heat preservation small door 250, as Figure 18 、 Figure 19 shown, a small door seal 253 is provided between the heat preservation small door 250 and the inner liner 220 of the door body. Specifically, the first shell 251 is provided with a support arm 2512 at the position where it cooperates with the inner liner 220 of the door body. The size of the support arm 2512 is larger than the size of the installation hole 201. An installation groove surrounding the installation hole 201 is provided on the support arm 2512, and the small door seal 253 is installed in the installation groove.

[0085] Specifically, in order to ensure that the heat-insulating small door 250 is reliably fixed to the door body 200, a locking device 400 is provided between the heat-insulating small door 250 and the inner door liner 220 of the door body. The locking device 400 is used to lock or unlock the heat-insulating small door 250 on the door body 200.

[0086] As Figures 17A - 17C 、 Figure 18 、 Figure 19 As shown, the locking device 400 includes a locking hook assembly provided on the heat-insulating small door 250 and a locking groove 221 provided on the inner door liner 220 of the door body. The locking hook assembly includes a locking hook penetrating through the heat-insulating small door 250. The locking hook can be switched between a first position and a second position. When the locking hook is in the first position, it can cooperate with the locking groove 221 to lock the heat-insulating small door 250. When the locking hook is in the second position, it disengages from the locking groove 221 to unlock the heat-insulating small door 250.

[0087] Specifically, in order to improve the reliability of the locking device 400, two locking grooves 221 and locking hooks are respectively provided. Among them, the locking grooves 221 are located on the upper and lower sides of the mounting hole 201. As Figures 18 - 23 shown, the locking hook assembly includes an upper locking hook 420, a lower locking hook 410 and a return spring 430. As Figure 22 shown, the lower locking hook 410 includes a hooking portion 414 that cooperates with the lower locking groove 221, a hinge portion 412 rotatably connected to the heat-insulating small door 250, and a pulling portion 411 located on the lower side of the heat-insulating small door 250. Among them, the pulling portion 411 and the hooking portion 414 are respectively located on both sides of the hinge portion 412. The lower locking hook 410 further includes a lower connecting portion 413 connected to the upper locking hook 420, and the lower connecting portion 413 extends above the pulling portion 411. Specifically, the end of the lower connecting portion 413 is formed into a T-shaped protrusion 4131. As Figure 20 shown, the upper locking hook 420 includes a hooking portion 421 that cooperates with the upper locking groove 221 and an upper connecting portion 423 connected to the lower locking hook 410. Specifically, the lower end of the upper connecting portion 423 is formed into an open slot structure 4231, and the T-shaped protrusion 4131 is inserted into the open slot 4231 to realize the connection between the upper locking hook 420 and the lower locking hook 410. A return spring 430 is provided between the upper locking hook 420 and the upper end surface of the heat-insulating small door 250. More specifically, a connecting shaft 422 is formed on the upper locking hook 420, and the return spring 430 is sleeved on the connecting shaft 422.

[0088] As Figure 20As shown, a guiding and positioning portion is formed on the inner surface of the second housing 252. The upper connecting portion 423 is snap-fitted onto the guiding and positioning portion, and the upper locking hook 420 can slide along the guiding and positioning portion. Specifically, the guiding and positioning portion is a hook 2521 formed on the inner surface of the second housing 252. The hook 2521 is located on the left and right sides of the upper connecting portion 423 and extends a certain distance in the up and down direction. The upper connecting portion 423 is snap-fitted between the two hooks 2521.

[0089] In the initial state, under the elastic force of the return spring 430, the upper locking hook 420 and the lower locking hook 410 are located at the first position to lock the heat preservation small door 250 and the inner door liner 220. When the user manually operates the lower locking hook 410, the lower locking hook 410 rotates around the hinge portion 412, and the hook portion 414 moves downward to disengage from the lower locking groove 221. At the same time, the connecting portion pushes the upper locking hook 420 upward, and the upper locking hook 420 disengages from the upper locking groove 221. The upper locking hook 420 and the lower locking hook 410 are located at the second position to unlock the heat preservation small door 250 and the inner door liner 220.

[0090] To ensure the aesthetic appearance of the refrigerator door body 200, referring to Figure 1 , Figure 2 As shown, a bar door 260 is provided on the refrigerator door body 200 at the area where the vacuum packaging device 300 is located. The lower end of the bar door 260 is hinged to the door body 200, and it can be flipped to a position perpendicular to the surface of the door body housing 210. The upper end of the bar door 260 is connected to the door body housing 210 through a first push-and-spring switch 212. With the structure of the bar door 260, when the bar door 260 is opened, a storage bag containing food can be placed on the bar door 260 for vacuum packaging treatment, which is convenient for the user to operate. When the bar door 260 is closed, the aesthetic appearance of the door body 200 is ensured.

[0091] The inner side of the bar counter door 260 further includes an operation panel 270 covering the outside of the installation cavity. An insertion port 271 is formed on the operation panel 270, and the lower surface of the insertion port 271 is flush with the upper surface of the first open cavity 311. In this way, the vacuum packaging device 300 can be entirely hidden behind the operation panel 270. When the user performs vacuum packaging, the opening of the storage bag can be directly inserted into the insertion port 271 of the operation panel 270 and directly extended to the upper surface of the first open cavity 311. When the upper support 320 moves downward, the opening of the storage bag can be placed in the vacuum extraction area 301. Specifically, the operation panel 270 is detachably connected to the door body housing 210. The operation panel 270 is also provided with a display and control device 272, and the display and control device 272 includes an indicating device for displaying the working state of the vacuum packaging device 300; and a control button for controlling the start or stop of the vacuum packaging device 300. The user can determine whether the storage bag can be taken out according to the working state of the vacuum packaging device 300 displayed by the display and control device 272.

[0092] When the user applies the vacuum packaging device 300, the storage bag to be packaged is inserted through the insertion port 271 provided on the operation panel 270. After being inserted in place (the storage bag abuts against the limiting rib 322), the user triggers the start button on the operation panel 270, the motor 341 starts, controls the upper support 320 to descend, and until the upper support 320 moves in place (the vacuum extraction area 301 is sealed), then controls the vacuum pump 331 to start, and performs vacuum extraction on the vacuum extraction area 301. The storage bag realizes vacuum extraction through the opening of the storage bag located in the vacuum extraction area 301; when the pressure sensor detects that the pressure value reaches the set negative pressure value, controls the vacuum pump 331 to stop and at the same time starts the heating device 370 to work. After the heating device 370 works for a set time, controls the electric balance valve to start; then controls the linear motor 341 to start and controls the upper support 320 to rise until the first open cavity 311 and the second open cavity 321 are separated; the display and control device 272 on the operation panel 270 indicates that the user can take out the storage bag, and the vacuum packaging of the storage bag is completed.
