[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0033] Figure 1 and Figure 8The embodiment of the vacuum fresh-keeping device of the present invention is shown, and the vacuum fresh-keeping device comprises a vacuum pumping component 10, a fresh-keeping box bracket 20 and a movable component 30. The vacuum pumping component 10 is provided with an air extraction interface 11, and the fresh-keeping box bracket 20 is movably mounted on the vacuum pumping component 10 through the movable component 30, and the fresh-keeping box bracket 20 is used to hold the fresh-keeping box 40. The fresh-keeping box bracket 20 comprises: a first state away from the vacuum pumping component 10, and a second state close to the vacuum pumping component 10.

[0034] By applying the technical solution of the present invention, when the fresh-keeping box 40 needs to be vacuumed, the fresh-keeping box bracket 20 is operated by the movable component 30 to move the fresh-keeping box bracket 20 to the first state, and the fresh-keeping box 40 can be placed on the fresh-keeping box bracket 20; thereafter, the fresh-keeping box bracket 20 can be operated to move the fresh-keeping box bracket 20 to the second state, and the vacuuming component 10 vacuums the fresh-keeping box 40. By adopting the technical solution of the present invention, it is more convenient to operate the vacuuming of the fresh-keeping box 40 through the fresh-keeping box bracket 20, and it is easy to use.

[0035] More preferably, Figure 8 As shown, in the technical solution of this embodiment, the fresh-keeping box bracket 20 also includes a third state in which it is attached to the vacuum component 10. In this way, after the vacuum fresh-keeping device is used, the space occupied by the vacuum fresh-keeping device can be reduced, thereby facilitating the application of the vacuum fresh-keeping device in the refrigerator and preventing the vacuum fresh-keeping device from occupying the effective use space of the refrigerator.

[0036] like Figure 2 Shown and Figure 8 As shown, in the technical solution of this embodiment, the fresh-keeping box bracket 20 includes a bottom plate 21 and a side plate 22. In the third state, the bottom plate 21 is in contact with the bottom surface of the vacuum component 10, and the side plate 22 surrounds the side of the vacuum component 10. When in use, the bottom plate 21 plays a major role in supporting the fresh-keeping box 40, and the side plate 22 plays a role in limiting the sliding of the fresh-keeping box 40 on the bottom plate 21. The above structural design can not only play a good supporting and limiting role for the fresh-keeping box 40, but also can well hide the fresh-keeping box bracket 20 in the third state.

[0037] like Figure 2 As shown, optionally, in the technical solution of the present embodiment, a limiting member 23 is provided on the fresh-keeping box bracket 20, and the limiting member 23 is used to limit the sliding of the fresh-keeping box 40 on the fresh-keeping box bracket 20. Preferably, in the technical solution of the present embodiment, the limiting member 23 is a limiting convex rib provided on the top surface of the bottom plate 21. More preferably, the limiting convex rib is T-shaped or cross-shaped. As other optional implementations, the limiting member 23 can also be provided on the side plate 22, or simultaneously provided on the bottom plate 21 and the side plate 22. In addition, the limiting convex rib can also be of other shapes as long as it plays a limiting role.

[0038] like Figure 4 and Figure 5 As shown, in the technical solution of the present embodiment, the vacuum fresh-keeping device also includes a fresh-keeping box 40, and a limiting groove 41 adapted to the shape of the limiting convex rib is formed at the bottom of the fresh-keeping box 40. By matching the limiting groove 41 with the shape of the limiting convex rib, better limiting of the fresh-keeping box 40 can be achieved. More preferably, in the technical solution of the present embodiment, an air valve 42 adapted to the air extraction interface 11 is provided on the fresh-keeping box 40, and in the second state, the air extraction interface 11 is connected to the air valve 42; in the first state, the air extraction interface 11 is separated from the air valve 42. The air valve 42 can be a rubber valve or a mechanical one-way valve, which mainly plays the role of preventing external air from entering the fresh-keeping box 40 after the air extraction interface 11 is separated from the air valve 42. In the technical solution of the present embodiment, the air valve 42 is a silicone air valve, which realizes the sealing, air intake and exhaust of the fresh-keeping box 40. When the air is pumped out, the external air pressure decreases. When the external air pressure is less than the air pressure inside the fresh-keeping box 40, the edge of the silicone valve rises, and the gas flows out through the air guide groove 22; after the air pumping stops, the silicone valve is compressed under the action of the air pressure to complete the seal. When it is necessary to restore the air pressure inside the box, press the top of the silicone valve, the edge of the silicone valve rises, the gas flows in through the groove, and the air pressure inside the box returns to atmospheric pressure. In addition, the air pressure inside the box can be judged by the thin part of the silicone valve. When the air pressure inside the box decreases, the degree of depression at the top of the silicone valve will increase accordingly. During the storage process after the vacuum pumping is completed, if the fresh-keeping box 40 leaks, the air pressure inside the fresh-keeping box 40 approaches the external air pressure, and the degree of depression of the silicone valve will gradually decrease. Through this design, the user can conveniently and intuitively observe the sealing condition of the fresh-keeping box 40, and timely re-vacuum the leaking fresh-keeping box 40.

[0039] like Figure 1 and Figure 3 As shown, in the technical solution of this embodiment, the movable component 30 includes a guide rail component 31 and a slider component 32. The guide rail component 31 is fixedly connected to the vacuum component 10, the slider component 32 is slidably mounted on the guide rail component 31, and the fresh-keeping box bracket 20 is mounted on the slider component 32. Through the cooperation of the guide rail component 31 and the slider component 32, the fresh-keeping box bracket 20 can achieve more stable movement. Preferably, in the technical solution of this embodiment, the guide rail component 31 and the slider component 32 are ball slide rail components, and the friction of the movement is smaller and more stable.

[0040] Optionally, the movable part 30 also includes a driving member, which is installed between the guide rail member 31 and the slider member 32, and the driving member drives the slider member 32 to move and drive the fresh-keeping box bracket 20 to the first state or the second state or the third state. In the technical solution of this embodiment, the driving member is a spring 33, and the spring 33 drives the slider member 32 to move to the second state or to the third state through elastic force. When in use, the elastic force of the spring 33 can be manually overcome to allow the fresh-keeping box bracket 20 to move to the first state. After the fresh-keeping box 40 is installed, the elastic force of the spring 33 can be used to allow the fresh-keeping box bracket 20 to move to the second state. Finally, after use, the elastic force of the spring 33 is used to allow the fresh-keeping box bracket 20 to move to the third state. Preferably, in the technical solution of this embodiment, a pull ring 24 is provided on the fresh-keeping box bracket 20, and the pull ring 24 is used to operate the fresh-keeping box bracket 20 to move, and the pull ring 24 is convenient for manually operating the fresh-keeping box bracket 20 to move to the above three states.

[0041] As other optional implementations, an electric push rod or other electric mechanical components or pneumatic mechanical components may also be used as a driving member to drive the slider member 32 .

[0042] like Figure 3 As shown, in the technical solution of this embodiment, the guide rail member 31 is provided with a first limiting structure 311, a second limiting structure 312 and a third limiting structure 313. The first limiting structure 311 cooperates with the slider member 32 to limit the fresh-keeping box bracket 20 to the first state, the second limiting structure 312 cooperates with the slider member 32 to limit the fresh-keeping box bracket 20 to the second state, and the third limiting structure 313 cooperates with the slider member 32 to limit the fresh-keeping box bracket 20 to the third state. In this way, the fresh-keeping box bracket 20 can have corresponding posture maintaining functions in the three states, so as to more stably maintain the fresh-keeping box bracket 20 in these three states.

[0043] like Figure 6 As shown, in the technical solution of this embodiment, the vacuum pumping component 10 includes a device body 12, in which a driving motor 13, a gear set 14 and a pump body 15 are arranged, and the driving motor 13 drives the pump body 15 to evacuate air through the gear set 14, and the pump body 15 is connected to the air extraction interface 11. When in use, the driving motor 13 drives the pump body 15 to work through the gear set 14, so that the air extraction interface 11 can achieve vacuum extraction of the fresh-keeping box 40. Preferably, the vacuum pumping component 10 also includes a hose 16, and the pump body 15 is connected to the air extraction interface 11 through the hose 16, and the hose 16 can facilitate the adjustment of the direction of the air extraction interface 11.

[0044] More preferably, Figure 4As shown, in the technical solution of this embodiment, a card slot 121 is provided on the device body 12, and the card slot 121 is used for installation. When in use, the vacuum fresh-keeping device can be conveniently installed on the refrigerator through the card slot 121.

[0045] The present invention also provides a refrigerator, such as Figure 7 and Figure 8 As shown, the refrigerator includes a vacuum preservation device, which is the above-mentioned vacuum preservation device. More preferably, in the technical solution of this embodiment, the refrigerator includes a box body 51 and a box door 52 arranged on the box body 51, and the vacuum preservation device is installed on the box door 52.

[0046] Preferably, the guide rail member 31 is also fixedly connected to the refrigerator door 52, and the two can be connected together by fixing screws. Preferably, the guide rail member 31 connects the three parts into a whole by fixing screws, and then fixes the device to the inner lining of the refrigerator door 52 by fixing screws. Reinforcement iron is embedded in the refrigerator foam layer to fix the screws. A decorative block is also provided on the guide rail member 31, which is used to cover the exposed guide rail to make the device more beautiful. When not in use, the device is naturally closed.

[0047] Preferably, a push switch is provided on the vacuuming component 10, or the air extraction interface 11 senses a certain pressure, the pump body is started, and the device starts to vacuumize the fresh-keeping box 40. At the same time, the vacuuming progress digital display on the vacuuming component 10 starts to display the vacuuming progress. During this process, the user can close the refrigerator door 52. After the conditions are met, the vacuuming device stops running, the fresh-keeping box 40 is vacuumed, and the device emits a prompt sound to remind the user. The working completion condition here can be the device running time or the air pressure sensed by the air pressure sensor. When the fresh-keeping box 40 is vacuumed, the user can continue to place it on the device, place it in the refrigerator for refrigeration, or remove the fresh-keeping box 40 and place it in the best storage place for the items in the box. The idle device can vacuum the next fresh-keeping box 40. When there is no vacuuming demand, after the fresh-keeping box 40 is removed, the device will be closed under the action of the spring 33 in the guide rail, and the occupied space becomes smaller.

[0048] In the technical solution of the present invention, vacuuming means to extract the air in the fresh-keeping box 40 so that the air pressure in the box drops to 101 kPa, i.e., below one atmosphere, and the final air pressure in the box can be 0.8 atmosphere or other values ​​suitable for food storage. It does not mean that the device can completely extract the air in the fresh-keeping box 40.

[0049] Compared with the prior art, the technical solution of the present invention can be applied to any model without making major changes to the refrigerator, thereby reducing application costs and promotion difficulty.

[0050] The beneficial effect of the technical solution of the present invention is that the user can use any number of fresh-keeping boxes 40 with the vacuum pumping component 10. Compared with other vacuum fresh-keeping devices, the storage space and storage position of this solution are not limited, and a large number of items can be stored. Moreover, the installation method of the vacuum pumping device is unified and is not limited by the size of the door body. It can be applied to different models without changing the device and door body structure. The vacuum pump and the air outlet are automatically compressed to improve the sealing of the air outlet. Compared with existing products, there is no need for manual pressing, and the vacuum pumping efficiency is higher.
