[0052] In some embodiments of this application, a refrigerator is provided, with reference to... Figure 1 The refrigerator has an approximate cuboid shape. The appearance of the refrigerator is defined by a cabinet 110 that defines the storage compartment and a plurality of cabinet doors 140 provided on the cabinet 110. The plurality of cabinet doors 140 are rotatably connected to the cabinet 110.

[0053] The cabinet 110 can be equipped with multiple separate refrigeration compartments 130. Each refrigeration compartment 130 can serve as an independent storage space, such as a freezer, refrigerator, or variable temperature compartment, to meet different refrigeration needs such as freezing, refrigeration, and variable temperature storage according to the different types of food. The multiple refrigeration compartments 130 can be arranged vertically or horizontally.

[0054] The cabinet 110 contains a cabinet liner 120, and the refrigeration chamber 130 is formed within the cabinet liner 120. It can be understood that multiple cabinet liners 120 can be installed inside the cabinet 110, and each cabinet liner 120 can form one or more refrigeration chambers 130.

[0055] The front of the refrigerator body 110 is provided with a door 140, which is used to open and close the refrigeration compartment 130. The door 140 is connected to the refrigerator body 110 by a hinge, allowing the door 140 to rotate around the axis of the hinge, thereby opening and closing the refrigerator door 140 and thus opening and closing the corresponding refrigeration compartment 130. It is understood that multiple doors 140 can be provided, each corresponding to a refrigeration compartment 130. Alternatively, multiple doors 140 can open and close a single refrigeration compartment 130 simultaneously.

[0056] The cabinet 110 houses a refrigeration assembly (not shown in the figure), which provides cooling capacity to the interior of the refrigerator to maintain a low-temperature environment in each refrigeration compartment 130. The refrigeration assembly includes a compressor, condenser, evaporator, throttling device, etc. The specific structure and connection relationship of the refrigeration assembly can be found in the relevant technical documentation on refrigeration assemblies, and will not be described in detail here.

[0057] The refrigerator includes a vacuum drawer 200, which is located inside the cabinet 110 and within the liner 120. Specifically, the liner 120 contains a drawer frame 300, which is located within the cooling compartment 130. The drawer frame 300 has a drawer cavity (not shown in the figure) with a front opening. The vacuum drawer 200 can be inserted into the drawer cavity through the front opening, thereby sealing the drawer cavity and forming a closed space inside. A vacuum pump 700 is then used to evacuate the vacuum, thus maintaining a certain vacuum environment inside the vacuum drawer 200.

[0058] It should be noted that the internal space of the vacuum drawer 200 can be used for both low-pressure storage and low-temperature storage of food.

[0059] Figure 2 This is a structural diagram of a vacuum drawer 200, a drawer frame 300, and an air duct component 400. Figure 3 This is a structural diagram of a vacuum drawer 200 and a drawer frame 300. Figure 4 This is a structural diagram of a vacuum drawer 200. Figure 5 An exploded view of a vacuum drawer 200.

[0060] In some embodiments of this application, the vacuum drawer 200 includes a drawer body 210. The drawer body 210 is a rectangular box structure with an open top surface. A storage cavity 211 is formed inside the drawer body 210. The storage cavity 211 is a cavity structure with an open top surface. Food can be placed into the storage cavity 211 through the open top surface of the storage cavity 211, or food can be taken out of the storage cavity 211 through the open top surface of the storage cavity 211.

[0061] The vacuum drawer 200 also includes a drawer door 220. The drawer door 220 is located at the end of the drawer body 210, such as the front end. The drawer door 220 is used to push and pull the drawer body 210, thereby allowing the entire vacuum drawer 200 to be pulled out within the drawer frame 300. At the same time, when the entire vacuum drawer 200 is fully pushed into the drawer frame 300, the drawer door 220 can close the front opening of the drawer cavity, thereby forming a closed cavity within the drawer frame 300.

[0062] Figure 6 This is a structural diagram of drawer door 220. Figure 7 for Figure 6 A structural diagram omitting the front panel. Figure 8 for Figure 6 The diagram shown is a structural representation of drawer door 220 as viewed from the Q1 side.

[0063] In some embodiments of this application, reference is made to Figure 8A sealing ring 270 is provided on the back side of the drawer door 220. The sealing ring 270 is annular. When the drawer body 210 and the drawer door 220 are assembled as one unit, the sealing ring 270 can surround the outer periphery of the front wall of the drawer body 210. When the vacuum drawer 200 is completely placed inside the drawer frame 300 inside the refrigerator, the sealing ring 270 can clamp at the front end of the drawer door 220 and the drawer frame 300, thereby sealing the drawer cavity and achieving the sealing of the vacuum drawer 200.

[0064] In some embodiments of this application, reference is made to Figure 7 and Figure 8 The drawer door 220 has an installation cavity 240 inside, which is connected to the external space of the drawer door 220. The drawer door 220 is provided with a ventilation hole 230, which is connected to the storage cavity 211 and the installation cavity 240.

[0065] When the vacuum drawer 200 needs to be opened, outside air can enter the storage cavity 211 through the mounting cavity 240 and the vent 230, thereby depressurizing the inside of the storage cavity 211 and releasing the vacuum state of the vacuum drawer 200 so that the vacuum drawer 200 can be pulled out.

[0066] In some embodiments of this application, reference is made to Figure 7 The vacuum drawer 200 also includes a pressure relief device 500, which is movably disposed in the mounting cavity 240 and configured to open and close the vent 230. Figure 17 This is a structural diagram of a pressure relief device 500. Figure 18 for Figure 17 The diagram shows a structural view of the pressure relief device 500 as viewed from the Q2 side.

[0067] When the pressure relief device 500 closes the vent 230, the vacuum drawer 200 can cooperate with the drawer frame 300 to form a sealed space for vacuuming operations. When the pressure relief device 500 opens the vent 230, outside air can enter the vacuum drawer 200 to relieve pressure inside the vacuum drawer 200.

[0068] In some embodiments of this application, the vacuum drawer 200 further includes a locking device 600. Figure 10 This is a structural diagram of a locking device 600. Figure 9 This is a structural diagram of a locking device 600 and a pressure relief device 500. The locking device 600 is configured to drive the rotating block 510 to rotate, thereby actively opening or closing the vent 230.

[0069] In some embodiments of this application, reference is made to Figures 5 to 8The drawer door 220 includes an inner panel 221 and an outer panel 222. The inner panel 221 is fixedly connected to the front end of the drawer body 210, and the outer panel 222 is disposed on the outside of the inner panel 221. A mounting cavity 240 is formed between the inner panel 221 and the outer panel 222. A ventilation hole 230 is provided on the inner panel 221.

[0070] An installation cavity 240 is formed inside the drawer door 220 by the inner panel 221 and the outer panel 222 for installing the pressure relief device 500. The inner panel 221 helps to improve the structural strength of the drawer door 220. When the internal pressure relief device 500 needs to be repaired, the outer panel 222 can be removed.

[0071] In some embodiments of this application, reference is made to Figures 5 to 7 The drawer door 220 includes a first panel 223. The first panel 223 is located on the outside of the drawer door 220, specifically, the first panel 223 is fixedly located on the outside of the inner panel 221. The first panel 223 has an opening 2231, through which the pressure relief device 500 is visible.

[0072] The drawer door 220 also includes a second panel 224. The second panel 224 is detachably disposed on the outside of the first panel 223, and covers the opening 2231.

[0073] The first panel 223 and the second panel 224 constitute the outer panel 222. When it is necessary to repair the pressure relief device 500 inside the drawer door 220, only the second panel 224 needs to be removed, without having to remove the entire outer panel 222, so that the pressure relief device 500 can be repaired, which is convenient for maintenance operations.

[0074] There is a type of drawer door with an integral outer panel. When the internal pressure relief device 500 needs to be repaired, the entire outer panel needs to be removed. Since the connecting rod 610 of the locking device 600 passes through the outer panel of the drawer door 220 and connects the connecting rod 610 to the pressure relief device 500, the overall removal of the outer panel also involves the removal of the locking device 600. Therefore, it is inconvenient to repair the pressure relief device 500.

[0075] In this embodiment, the outer panel 222 of the drawer door 220 is designed as a split type, including a first panel 223 and a second panel 224. The connecting rod 610 of the locking device 600 passes through the first panel 223. The first panel 223 has an opening 2231 through which the pressure relief device 500 is visible. The second panel 224 covers the opening 2231 to conceal the pressure relief device 500. When it is necessary to repair the internal pressure relief device 500, only the second panel 224 needs to be removed without involving the locking device 600, which facilitates the repair of the pressure relief device 500.

[0076] In some embodiments of this application, reference is made to Figure 7 The first panel 223 includes a main body plate 2232 and a side plate 2233 with an integral structure. The side plate 2233 is disposed on the periphery of the main body plate 2232. The main body plate 2232 is provided with an opening 2231. The second panel 224 is detachably disposed on the main body plate 2232.

[0077] The main body panel 2232 is located on the front side of the drawer door 220, and the side panel 2233 is fixedly connected to the inner panel 221 of the drawer door 220. There is a gap between the main body panel 2232 and the inner panel 221 to facilitate the installation of the pressure relief device 500. The second panel 224 is detachably mounted on the main body panel 2232. The second panel 224 not only covers the pressure relief device 500 but also helps to improve the structural strength of the first panel 223.

[0078] In some embodiments of this application, the second panel 224 covers the main body panel 2232. In other words, the second panel 224 forms the front view of the drawer door 220, maintaining the visual consistency of the drawer door 220.

[0079] In some embodiments of this application, the area of ​​the opening 2231 accounts for 60-80% of the area of ​​the main body plate 2232. The area of ​​the opening 2231 is moderate, which facilitates the maintenance of the pressure relief device 500, and the structural area of ​​the outer periphery of the opening 2231 facilitates the installation of the second panel 224.

[0080] In some embodiments of this application, the second panel 224 is made of tempered glass to improve structural strength and enhance visual appeal.

[0081] In some embodiments of this application, the second panel 224 is bonded and fixed to the first panel 223. The first panel 223 is provided with a groove (not shown) for accommodating double-sided adhesive, and the fixed connection between the first panel 223 and the second panel 224 is achieved by double-sided adhesive.

[0082] The groove accommodates double-sided adhesive, which not only fixes the first panel 223 and the second panel 224 together, but also prevents a large gap between them.

[0083] In some embodiments of this application, reference is made to Figure 17 and Figure 18 The pressure relief device 500 includes a rotating block 510. The rotating block 510 is rotatably disposed within the mounting cavity 240.

[0084] The pressure relief device 500 also includes a pressure relief valve 520. The pressure relief valve 520 is disposed on the rotating block 510 and is configured to open or close the vent 230.

[0085] The pressure relief device 500 also includes a torsion spring 530. The torsion spring 530 is disposed between the rotating block 510 and the inner wall of the mounting cavity 240, and is configured to apply a force to the rotating block 510 to move the pressure relief valve 520 toward the vent 230.

[0086] When the rotating block 510 moves toward the vent 230, it drives the pressure relief valve 520 to move toward the vent 230, thus blocking the vent 230. The torsional force of the torsion spring 530 effectively and tightly fixes the pressure relief valve 520 to the vent 230, improving the sealing reliability of the vacuum drawer 200.

[0087] In some embodiments of this application, the pressure relief valve 520 is disposed at the bottom of the rotating block 510 and faces the vent 230. Under the gravity of the rotating block 510, the rotating block 510 can rotate downward, so that the pressure relief valve 520 approaches and blocks the vent 230, thereby sealing the vacuum drawer 200.

[0088] The pressure relief valve 520 and the torsion spring 530 are located at the same end of the rotating block 510. The pressure relief valve 520 is positioned directly below the torsion spring 530, allowing the torsion spring 530 to press and fix the pressure relief valve 520 onto the vent hole 230 via the rotating block 510. In other words, the torsional force of the torsion spring 530 can be transmitted to the pressure relief valve 520 via the rotating block 510, ensuring that the pressure relief valve 520 is properly stressed and pressed and fixed onto the vent hole 230, thus tightly sealing the vent hole 230 and effectively increasing the sealing performance and reliability of the vacuum drawer 200.

[0089] In some embodiments of this application, a rotating block 510 is provided with a rotating shaft portion 511, which is rotatably connected to the inner wall of the mounting cavity 240, and a torsion spring 530 is sleeved on the rotating shaft portion 511. Specifically, a rotating shaft portion 511 is formed at the top edge of the rotating block 510, and the rotating shaft portion 511 extends laterally. A receiving groove 2211 is provided inside the mounting cavity 240, which is formed on the inner plate 221. A vent hole 230 is provided on the groove wall of the receiving groove 2211, and the two ends of the rotating shaft portion 511 are rotatably connected to the left and right sides of the groove wall of the receiving groove 2211, respectively.

[0090] Reference Figure 10 and Figure 19 A first limiting part 2212 is provided on the inner wall of the mounting cavity 240, that is, a first limiting part 2212 is provided on the groove wall of the receiving groove 2211, for example, the first limiting part 2212 is a slot. A second limiting part 512 is provided on the rotating block 510, for example, the second limiting part 512 is a slot. One end of the torsion spring 530 is provided in the first limiting part 2212, and the other end is provided in the second limiting part 512.

[0091] The first limiting part 2212 and the second limiting part 512 limit both ends of the torsion spring 530, thereby improving the installation reliability of the torsion spring 530.

[0092] In some embodiments of this application, reference is made to Figure 10 and Figure 11 The locking device 600 includes a connecting rod portion 610. The connecting rod portion 610 extends in the transverse direction (the width direction of the drawer door 220) and is fixedly connected to the rotating block 510, driving the rotating block 510 to rotate. The connecting rod portion 610 extends through the mounting cavity 240, with both ends protruding from the mounting cavity 240. Specifically, the connecting rod portion 610 extends through the side plate 2233 of the inner plate 221. The connecting rod portion 610 is visible through the opening 2231.

[0093] The locking device 600 also includes a connecting part 620. The two ends of the connecting rod part 610 are respectively provided with connecting parts 620, and the connecting parts 620 are rotatably connected to the drawer door 220. Figure 12 This is a structural diagram of the connecting part 620. Figure 13 This is a structural diagram of the connecting part 620 as viewed from the other side.

[0094] The locking device 600 also includes a handle portion 630, which is connected between two connecting portions 620. The handle portion 630 is located on the outside of the drawer door 220 and extends along the width direction of the drawer door 220. Figure 14 This is a structural diagram of the handle part 630.

[0095] When the handle 630 is lifted upward, the handle 630 can drive the two connecting parts 620 to rotate upward, which in turn drives the connecting rod 610 to move upward. The connecting rod 610 can drive the rotating block 510 to rotate upward, so that the pressure relief valve 520 moves away from the vent 230. At this time, the vent 230 is opened, and the vacuum drawer 200 is depressurized.

[0096] When the handle 630 is released, the torsional force of the torsion spring 530 and the gravity of the pressure relief device 500 and locking device 600 cause the rotating block to rotate downwards, bringing the pressure relief valve 520 closer to and blocking the vent 230. At this time, the vent 230 is closed, and the pressure relief valve 520 can press and seal the vent 230, making the inside of the vacuum drawer 200 sealed, allowing the vacuum drawer 200 to be evacuated. At the same time, the rotating block 510 can drive the connecting rod 610 to move downwards, and the connecting rod 610 drives the two connecting parts 620 to rotate downwards, thereby driving the handle 630 to move downwards and reset.

[0097] In some embodiments of this application, reference is made to Figure 12 and Figure 13 The connecting part 620 is provided with an insertion part 621. (See reference...) Figures 14 to 16The insertion part 621 is inserted into the inner cavity 633 of the handle part 630.

[0098] When installing the connecting part 620 and the handle part 630, first insert the insert part 621 into the inner cavity 633 of the handle part 630 to play a pre-positioning role, so that the insert part 621 is aligned with the screw hole in the handle part 630, and then fasten the connecting part 620 and the handle part 630 with the first screw 640. This facilitates installation and helps to improve installation efficiency.

[0099] In some embodiments of this application, reference is made to Figure 13 and Figure 16 The insertion part 621 includes an integral insertion part section 6211 and an insertion part section 6212.

[0115] In some embodiments of this application, the refrigerator further includes an air duct component 400, which is disposed on the top of the drawer frame 300. Figure 21 This is a structural diagram of the air duct component 400 and the drawer frame 300. Figure 22 This is a structural diagram of air duct component 400. Figure 26 This is a top view of the air duct component 400. Figure 27 for Figure 26 BB-direction sectional view, Figure 27 The middle arrow indicates the direction of gas flow.

[0116] The air duct component 400 includes an air duct cavity 480, an air inlet 430, and an air outlet 440. The air duct cavity 480 is located at the top of the drawer frame 300. The air inlet 430 connects the air duct cavity 480 to the refrigerator's air duct. The air outlet 440 is connected to the air duct cavity 480. Cold air from the refrigerator's air duct enters the air duct cavity 480 through the air inlet 430 and then flows out through the air outlet 440. The cold air is blown towards the outer periphery of the drawer frame 300 to provide a low-temperature environment for the vacuum drawer 200.

[0117] The air duct 400 also includes a first air guide 450, which is configured to guide the cold air flowing from the air outlet 440 to the side of the drawer frame 300.

[0118] There is a type of air duct component where the cold air flowing out of the air outlet has no guiding structure. The cold air immediately spreads out on the outside of the drawer frame and cannot effectively surround the outer perimeter of the drawer frame, thereby reducing the utilization rate of the cold air and reducing the cooling effect of the vacuum drawer.

[0119] In this embodiment, a first air guide 450 is provided on the side of the air duct 400. The first air guide 450 guides the cold air flowing out of the air outlet 440 to the side of the drawer frame 300. In this way, the cold air flowing out of the air outlet 440 of the air duct 400 can effectively surround the drawer frame 300, improve the utilization rate of cold air, and improve the cooling effect of the vacuum drawer 200.

[0120] In some embodiments of this application, the air outlet 440 is located on the top side of the drawer frame 300, and the first air guide 450 extends from the air outlet 440 to the side of the drawer frame 300 to guide the cold air flowing out of the air outlet 440 to the side of the drawer frame 300.

[0121] Cold air flows out from the top air outlet 440 and then flows to the side of the drawer frame 300 under the guidance of the first air guide 450. The first air guide extends from the air outlet 440 to the side of the drawer frame 300 to improve the guiding effect of the first air guide 450 on the cold air.

[0122] In some embodiments of this application, the air duct 400 further includes a second air guide 460, which is located on the side of the drawer frame 300. There is a gap between the second air guide 460 and the side wall of the drawer frame 300. The second air guide 460 is configured to guide the cold air from the first air guide 450 to the lower side of the drawer frame 300.

[0123] The first air guide 450 directs the cold air to the left and right sides of the drawer frame 300, and the second air guide 460 directs the cold air to the lower side of the drawer frame 300. In this way, the cold air forms an effective airflow circulation around the drawer frame 300, avoiding disorderly diffusion of cold air, improving the utilization rate of cold air, and thus improving the cooling effect.

[0124] In some embodiments of this application, the air duct component 400 includes a first air duct cover 410. Figure 23 This is a structural diagram of the first air duct cover plate 410. Figure 24 This is a structural diagram of the first air duct cover 410 viewed from the bottom side. The first air duct cover 410 is located on the top side of the drawer frame 300, and the side of the first air duct cover 410 protrudes from the side of the drawer frame 300.

[0125] The air duct component 400 also includes a second air duct cover 420. Figure 25 This is a structural diagram of a second air duct cover plate 420. The second air duct cover plate 420 is disposed on the top side of the first air duct cover plate 410. The first air duct cover plate 410 and the second air duct cover plate 420 form an air duct cavity 480. An air outlet 440 is provided on the side wall of the air duct cavity 480. There is a distance between the air outlet 440 and the side of the first air duct cover plate 410.

[0126] In other words, a recessed area 411 is formed on the first air duct cover plate 410, and a second air duct cover plate 420 is disposed on the top side of the recessed area 411 to cover the recessed area 411, forming an air duct cavity 480 within the recessed area 411. An air outlet 440 is provided on the side wall of the recessed area 411. The air outlet 440 is a certain distance from the left and right side walls of the drawer frame 300. A first air guide 450 is located outside the recessed area 411, extending from the air outlet 440 to the left and right sides of the drawer frame 300. The recessed area 411 and the first air guide 450 are an integral structure, both covering the top of the drawer frame 300. The cold air flowing out from the air outlet 440 is blocked by the upper first air guide 450, preventing it from diffusing upwards, and instead flows to the left and right sides of the drawer frame 300.

[0127] In this embodiment, the air duct component 400 increases the area of ​​the first air duct cover 410, so that the first air duct cover 410 guides the cold air flowing out of the air outlet 440 without changing the existing air duct structure and the related structure of the drawer frame 300, which is easy to implement.

[0128] In some embodiments of this application, reference is made to Figure 23 and Figure 24 The first air duct cover plate 410 is provided with an air guide groove 470, which extends from the air outlet 440 to the side of the first air duct cover plate 410, and the bottom side of the air guide groove 470 is open.

[0129] In other words, an air guide trough 470 is provided on the first air guide section 450, the air guide trough 470 is directly opposite the air outlet 440, the air guide trough 470 guides the cold air flowing out of the air outlet 440, and improves the gas guiding effect.

[0130] In some embodiments of this application, reference is made to Figure 24 and Figure 27 The air guide 470 includes an air guide section 471 and an air guide section 472. The air guide section 471 is located on the top side of the drawer frame 300. The air guide section 471 extends from the air outlet 440 to the left or right side of the drawer frame 300. The air guide section 472 extends in an arc shape from the air guide section 471 to the bottom side of the drawer frame 300.

[0131] The first section 471 of the air guide channel first guides the cold air to the side of the drawer frame 300, and the second section 472 of the air guide channel then extends the cold air to the bottom of the drawer frame 300, so that the cold air can effectively form an airflow circulation around the drawer frame 300.

[0132] In some embodiments of this application, a first flange 412 is provided on the side of the first air duct cover 410. The first flange 412 is located on the side of the drawer frame 300, and there is a gap between the first flange 412 and the side of the drawer frame 300.

[0133] In other words, the first flange 412 constitutes the second air guide 460 of the air duct 400. The first flange 412 further guides the cold air to the bottom side of the drawer frame 300, preventing the cold air from spreading upward and improving the utilization rate of the cold air.

[0134] In some embodiments of this application, reference is made to Figure 21 and Figure 24 The first air duct cover plate 410 has a second flange 413 on its side. The second flange 413 is located on the back side of the drawer frame 300. The air inlet 430 is located on the second flange 413. The first flange 412 and the second flange 413 are connected.

[0135] The first flange 412 is designed so that the air inlet 430 is located on the rear side of the drawer frame 300, which facilitates the connection between the air inlet 430 and the refrigerator's air duct.

[0136] In some embodiments of this application, the air duct 400 includes a plurality of air outlets 440, which helps to improve the uniformity of cold air distribution.

[0137] In some embodiments of this application, an air guiding structure 421 is provided in the air duct cavity 480 to guide the cold air in the air duct cavity 480 to the air outlet 440, which helps to improve the efficiency of cold air delivery.

[0138] For example, refer to Figure 25 The air guide structure 421 is a groove structure formed on the second air duct cover plate 420 to form a channel for gas flow.
