[0012] FIG. 1 is a structural diagram of a refrigerator, in accordance with some embodiments of the present disclosure, and the refrigerator is approximately in a shape of a cuboid. An appearance of the refrigerator is defined by a storage compartment 100 defining a storage space and a plurality of door bodies 200 provided in the storage compartment 100. The door body 200 includes a door shell 210 located outside the storage compartment 100, a door liner 220 located inside the storage compartment 100, an upper end cover 230, a lower end cover 240 and a foamed layer located among the door shell 210, the door liner 220, the upper end cover 230 and the lower end cover 240.

[0013] The storage compartment 100 has a box body 300 with openings, and the storage compartment 100 is vertically divided into a freezing compartment 110 located below and a refrigerating compartment 120 located above. Each of separated spaces may have an independent storage space.

A space above the freezing compartment 110 is divided into left and right spaces, so as to form the refrigerating compartments 120, respectively. The refrigerating compartment 120 may be selectively opened or closed through a refrigerating compartment door pivotally mounted on the refrigerating compartment 120.

[0014] FIG. 2 is a schematic diagram showing an assembly structure of a preservation box, a vacuuming joint assembly and a mounting base, in accordance with some embodiments of the present disclosure. FIG. 3 is a schematic structural diagram of the vacuuming joint assembly shown in FIG. 2 after being rotated upward (the preservation box being omitted). Referring to FIGS. 1 to 3, the refrigerator in the present disclosure further includes a preservation box 400 and a vacuuming assembly 500.

[0015] A storage cavity 410 is formed in the preservation box 400. The preservation box 400 is detachably connected to the door body 200 (specifically, the door liner 220), so as to facilitate the removal of the preservation box 400 from the door body 200 and improve the convenience of use of the preservation box 400.

[0016] The preservation box 400 includes a box body and a cover body, and the cover body is provided with a vacuuming interface portion 420. The vacuuming interface portion 420 is used to cooperate with the vacuuming assembly 500, so that the vacuuming assembly 500 communicates with the storage cavity 410 and vacuumizes the storage cavity 410.

[0017] The vacuuming assembly 500 may make the preservation box 400 achieve a vacuum state inside thereof. The vacuum state here is not an absolute vacuum state, but is actually a low-pressure state, so as to improve the preservation effect of the items stored in the preservation box 400. Exemplarily, a vacuum degree in the preservation box 400 is 0.6 MPa to 0.9 MPa inclusive.

[0018] The vacuuming assembly 500 includes a vacuum pump 530, a vacuuming pipeline 520 and a vacuuming joint assembly 510. The vacuuming pipeline 520 communicates the vacuum pump 530 with the vacuuming joint assembly 510. The vacuuming joint assembly 510 is detachably connected to the vacuuming interface portion 420. The vacuum pump 530 provides vacuuming power for the entire vacuuming assembly 500.

[0019] When it is necessary to vacuumize the storage cavity 410, the vacuuming joint assembly 510 is communicated with the storage cavity 410. That is, the vacuuming joint assembly 510 is connected to the vacuuming interface portion 420. In this case, the vacuum pump 530 is turned on, and the air in the storage cavity 410 may be discharged to the vacuum pump through the vacuuming joint assembly 510 and the vacuuming pipeline 520, so as to achieve the negative pressure in the storage cavity 410.

[0020] In some embodiments of the present disclosure, the vacuum pump 530 may be mounted on the upper end cover 230 of the door body, and the vacuuming pipeline 520 led out from the vacuuming joint assembly 510 may extend through the foamed layer of the door body 200 to the upper end cover 230 and communicate with the vacuum pump 530.

[0021] In some embodiments of the present disclosure, referring to FIG. 1, the door liner 220 is provided with a shelf 260. The preservation box 400 is directly placed in the shelf 260, so as to achieve the detachable connection between the preservation box 400 and the door liner 220. When it is necessary to remove the preservation box 400 from the refrigerator, the preservation box 400 may be directly removed from the shelf 260.

[0022] In some embodiments of the present disclosure, referring to FIG. 1, the vacuuming joint assembly 510 is provided proximate to a side of the door body 200 hinged with the box body 300 of the refrigerator. In this way, the torque borne by the vacuuming joint assembly 510 is small when the door body 200 is opened or closed, which is conducive to improving the stability of the vacuuming joint assembly 510.

[0023] In some other embodiments, the vacuuming joint assembly 510 may also be provided away from the side of the door body 200 hinged with the box body 300. In this way, the vacuuming joint assembly 510 is closer to the user side, which is convenient for the user to perform related operations on the vacuuming joint assembly 510.

[0024] The start and stop of the vacuuming assembly 500 is controlled by a key switch 900.

[0025] FIG. 16 is a schematic structural diagram of a mounting cover plate mounted with a key switch, in accordance with some embodiments. FIG. 17 is a sectional view of the mounting cover plate shown in FIG. 16. FIG. 18 is an exploded view of the mounting cover plate shown in FIG. 16. Referring to FIGS. 16 to 18, the vacuuming joint assembly 510 is disposed on the door liner 220. The door body 200 is provided with the key switch 900. The key switch 900 is coupled to the vacuum pump for communication, so as to control the start and stop of the vacuum pump 530.

[0026] During the vacuuming process of the vacuuming assembly 500, if the key switch 900 is pressed, the vacuum pump 530 is immediately stopped, so as to improve the safety of the vacuuming of the system.

[0027] FIG. 4 is a cross-sectional view of a vacuuming joint assembly, in accordance with some embodiments. FIG. 5 is a schematic structural diagram of a lower cover body of the vacuuming joint assembly shown in FIG. 4. FIG. 6 is a schematic structural diagram of an upper cover body of the vacuuming joint assembly shown in FIG. 4.

Referring to FIGS. 4 to 7, the vacuuming joint assembly 510 includes an upper cover body 511 and a lower cover body 512, the upper cover body 511 is of a flat plate structure, and the lower cover body 512 includes a bottom plate 5125 and a peripheral side plate 5126. After connecting (e.g., clamping) the upper cover body 511 and the lower cover body 512, an airflow channel is formed between the upper cover body 511 and the lower cover body 512. The vacuuming pipeline 520 is connected to the upper cover body 511 or the lower cover body 512 and communicated with the airflow channel.

[0028] In a case where the vacuuming joint assembly 510 is connected to the vacuuming interface portion 420, specifically, the lower cover body 512 is connected to the vacuuming interface portion 420, and the airflow channel is communicated with the storage cavity 410. In this case, the vacuum pump 530 is turned on, and the air in the storage cavity 410 may be discharged to the vacuum pump 530 through the airflow channel and the vacuuming pipeline 520.

[0029] The vacuuming pipeline 520 is led out from the upper cover body 511 or the lower cover body 512 and extends to the mounting base 600, and then leads to the vacuum pump 530. The vacuuming pipeline 520 is hidden between the upper cover body 511 and the lower cover body 512, and is hidden in the mounting base 600, so as to prevent the vacuuming pipeline 520 from being exposed.

[0030] Exemplary, the present disclosure provides two examples of the vacuuming joint assembly 510, the first example is that the vacuuming pipeline 520 is connected to the lower cover body 512, and the second example is that the vacuuming pipeline 520 is connected to the upper cover body 511, and details will be described below.

[0031] In the first example, the vacuuming pipeline 520 is connected to the lower cover body 512, referring to FIGS. 4 to 6.

[0032] The upper cover body 511 is provided with an annular upper cover protruding portion 5111, and the upper cover protruding portion 5111 extends toward the lower cover body 512.

[0033] The lower cover body 512 is provided with an annular lower cover protruding portion (marked as the lower cover protruding portion I 5121) correspondingly, and the lower cover protruding portion I 5121 extends toward the upper cover body 511. The lower cover body 512 is provided with a lower cover air inlet 5127 in a region surrounded by the lower cover protruding portion I 5121. The lower cover protruding portion I 5121 is provided with a first pipe joint 5251, and the vacuuming pipeline 520 is connected to the first pipe joint 5251.

[0034] After the upper cover body 511 and the lower cover body 512 are clamped together, the upper cover protruding portion 5111 is inserted into the inner periphery of the lower cover protruding portion I 5121, and a top of the lower cover protruding portion I 5121 abuts against the upper cover body 511. The upper cover protruding portion 5111 and the lower cover protruding portion I 5121 enclose a cavity, and the lower cover air inlet 5127 and the first pipe joint 5251 communicate with the cavity, so as to form the airflow channel. When vacuuming, the air in the storage cavity 410 flows through the lower cover air inlet 5127, the cavity enclosed by the upper cover protruding portion 5111 and the lower cover protruding portion I 5121, the first pipe joint 5251 to the vacuuming pipeline 520 in sequence.

[0035] In some embodiments of the present disclosure, a sealing loop 513 is provided between a top surface of the lower cover protruding portion I 5121 and the upper cover body 511, so as to seal the airflow channel and improve the vacuuming effect.

[0036] In some embodiments of the present disclosure, an annular lower cover protruding portion II 5122 is further provided in a region surrounded by the lower cover protruding portion I 5121, and the lower cover protruding portion II 5122 has a certain gathering and guiding effect on the airflow. A vent hole 51221 may be provided on the lower cover protruding portion II 5122 to facilitate air circulation.

[0037] In some embodiments of the present disclosure, the second magnet 5112 is fixed in the region surrounded by the upper cover protruding portion 5111 by means of gluing or the like, so as to achieve the fixed installation of the second magnet 5112 in the vacuuming joint assembly 510. In a case where the installation structure of the second magnet 5112 fails, the lower cover protruding portion II 5122 also has a certain protective effect on the second magnet 5112, so as to prevent the second magnet 5112 from falling and covering the lower cover air inlet 5127 and thus affecting the vacuuming process.

[0038] In some embodiments of the present disclosure, the bottom plate 5125 of the lower cover body is provided with a plurality of screw mounting columns 51251, and the plurality of screw mounting columns 51251 are symmetrically arranged around the outer periphery of the lower cover protruding portion I 5121. The upper cover body 511 is provided with a plurality of screw mounting countersinks 5114 correspondingly, so as to achieve the fixed installation of the upper cover body 511 and the lower cover body 512.

[0039] A rear end of the peripheral side plate 5126 of the lower cover body is provided with a clamping groove 51261, and a rear end of the upper cover body 511 is provided with a hook 5115 correspondingly. The clamping groove 51261 is clamped with the hook 5115, which may further improve the connection reliability between the upper cover body 511 and the lower cover body 512.

[0040] In some embodiments of the present disclosure, a surface of the upper cover body 511 is provided with a decorative plate 5116, such as an acrylic plate. The decorative plate 5116 covers the screw mounting countersinks 5114 and the screws 514, so as to improve the aesthetics of the vacuuming joint assembly 510.

[0041] In some embodiments of the present disclosure, the upper cover body 511 is further provided with a plurality of third magnets 5113, and the plurality of third magnets 5113 are symmetrically arranged on the outer periphery of the second magnet 5112, that is to say, the plurality of third magnets 5113 are symmetrically arranged around the outer periphery of the upper cover protruding portion 5111. The plurality of third magnets 5113 and the second magnet 5112 have an attraction effect, thereby further positioning the second magnet 5112 and improving the stability of the second magnet 5112. Correspondingly, the bottom plate 5125 of the lower cover body is provided with a column 51252, and column 51252 abuts against the third magnet 5113, so as to improve the installation reliability of the third magnets 5113 and prevent the third magnets 5113 from falling.

[0042] In some embodiments of the present disclosure, the lower cover body 512 is provided with a lower cover inserting portion 5123. The lower cover inserting portion 5123 is provided with a soft rubber portion 5124, the soft rubber portion 5124 is used for sealing with the vacuuming interface portion 420.

[0043] Referring to FIG. 4, the vacuuming interface portion 420 includes a groove portion 421 disposed on the preservation box 400. A vent 422 is provided in a region surrounded by the groove portion 421, and a pressure relief valve 423 is provided at the vent 422.

[0044] When the vacuuming joint assembly 510 is connected to the vacuuming interface portion 420 for vacuuming, the soft rubber portion 5124 is sealed and clamped in the groove portion 421. The air in the storage cavity 410 flows to the lower cover air inlet 5127 through the vent 422, and then flows to the vacuuming pipeline 520 through the airflow channel. After the vacuuming is completed, the vacuuming joint assembly 510 is separated from the vacuuming interface portion 420, and the pressure relief valve 423 blocks the vent 422 to maintain the negative pressure in the storage cavity 410.

[0045] In the present disclosure, the soft rubber portion 5124 has a certain height. In a case where the vacuuming joint assembly 510 is connected to the vacuuming interface portion 420, there is a certain distance between the lower cover body 512 and the pressure relief valve 423. The distance provides space for the up-down displacement of the pressure relief valve 423, and further forms an air buffering cavity 515. The air buffering cavity 515 buffers the air flow to facilitate the air circulation.

[0046] In some embodiments of the present disclosure, a concave portion 5128 is formed on the lower cover body 512 in the region surrounded by the lower cover inserting portion 5123. The concave portion 5128 is recessed toward a direction proximate to the upper cover body 511, and the lower cover air inlet 5127 is disposed at the concave portion 5128. The concave portion 5128 may gather and guide the air to facilitate the air circulation.

[0047] In some embodiments of the present disclosure, an arc transition portion 5129 is formed between the lower cover inserting portion 5123 and the outer peripheral surface of the lower cover body 512. Specifically, the arc transition portion 5129 is formed between the lower cover inserting portion 5123 and the peripheral side plate 5126 of the lower cover body. The arc transition portion 5129 prevents the lower cover body 512 from being excessively proximate to an upper end surface of the preservation box 400, and provides an operating space for the user to perform displacement operations on the vacuuming joint assembly 510.

[0048] In some embodiments of the present disclosure, the rear end of the peripheral side plate 5126 of the lower cover body is provided with a through hole 51263. The vacuuming pipeline 520 led out from the first pipe joint 5251 enters an interior of the mounting base 600 through the through hole 51263. The through hole 51263 extends in the vertical direction. When the vacuuming joint assembly 510 is displaced, the through hole 51263 provides a large space for the vacuuming pipeline 520 to move.

[0049] In the second embodiment, the vacuuming pipeline 520 is connected to the upper cover body 511, referring to FIG. 7. Most of the structures of the vacuuming joint assembly 510 shown in FIG. 7 are same as that of the vacuuming joint assembly 510 shown in FIG. 4, and only the differences between the two vacuuming joint assemblies 510 will be described below.

[0050] The upper cover body 511 is provided with an annular upper cover protruding portion 5111. The upper cover protruding portion 5111 extends toward the lower cover body 512. The upper cover protruding portion 5111 is provided with a first pipe joint 5251. The vacuuming pipeline 520 is connected to the first pipe joint 5251. The lower cover body 512 is provided with an annular lower cover protruding portion (marked as the lower cover protruding portion I 5121). The lower cover protruding portion I 5121 extends toward the upper cover body 511. The lower cover body 512 is provided with a lower cover air inlet 5127 in the region surrounded by the lower cover protruding portion I 5121. The upper cover protruding portion 5111 is inserted into an outer periphery of the lower cover protruding portion I 5121 and abuts against the lower cover body 512.

[0051] A sealing loop 513 is provided between a lower end of the upper cover protruding portion 5111 and the lower cover body 512, so as to improve the airtightness of the airflow channel.

[0052] In the vacuuming joint assembly 510 shown in FIG. 7, the second magnet 5112 is disposed in the region surrounded by the upper cover protruding portion 5111. In this case, the lower cover protruding portion I 5121 protects the second magnet 5112, so as to prevent the second magnet 5112 from falling due to failure of the installation structure and covering the lower cover air inlet 5127, which affects the vacuuming process.

[0053] In some embodiments of the present disclosure, with continuing reference to FIGS. 1 to 3, the door body 200 is provided with a mounting base 600, and the vacuuming joint assembly 510 is disposed on the mounting base 600.

[0054] The installation of the vacuuming joint assembly 510 is achieved through the mounting base 600. On one hand, it is convenient to manufacture the door body 200. There is no requirement for the door body 200 to get excessive structural changes, and the door body 200 only needs to be made corresponding adaptive structural adjustments according to the structure of the mounting base 600. On the other hand, according to the installing manner of the vacuuming joint assembly 510, only a partial structure of the mounting base 600 needs to be adjusted. Considering the above two aspects, installation of the vacuuming joint assembly 510 through the mounting base 600 may significantly reduce manufacturing cost as well as research and development cost.

[0055] In addition, the mounting base 600 provides a certain installation space for the layout of the vacuuming pipeline 520 and the installation of rotated electrical components used for controlling the start and stop of the vacuuming assembly 500.

[0056] Referring to FIGS. 8 to 15 for the schematic structural diagrams of the mounting base 600, and with reference to FIGS. 2 and 3, the mounting base 600 is disposed on the door body 200.
