[0001] The invention belongs to the technical field of fresh-keeping, in particular to a vacuum fresh-keeping device and a refrigerator. Background Art

[0002] With the progress of society and the development of the refrigerator industry, consumers have increased their demand for the freshness of food. Based on this, vacuum fresh-keeping containers installed inside refrigerators have emerged. For example, the invention patent with application number CN202210622491.8 discloses a vacuum fresh-keeping device and refrigerator, which uses a fresh-keeping container and a vacuuming assembly installed on the refrigerator door to achieve vacuuming of the fresh-keeping container. However, the vacuuming assembly needs to be connected to a driving power supply via a connecting wire placed in the door, which not only requires complicated wiring but also makes the fresh-keeping container only usable inside the refrigerator. The invention patent with application number CN201821313443.6 discloses a wireless vacuum cooking cup with a vacuuming device and a wirelessly rechargeable power supply installed on the cup lid, so that the vacuuming device does not need to be connected to an external power supply. Although this improves the flexibility of the vacuum cooking cup to a certain extent, when the wireless charging power supply needs to be charged, it still needs to be connected to an external power supply through a wireless charger, which is not suitable for fresh-keeping containers placed inside the refrigerator.

[0003] Therefore, how to provide a flexible power supply for the vacuum device of the vacuum preservation device has become a technical problem that needs to be solved urgently in the industry. Summary of the Invention

[0004] The main purpose of the present invention is to provide a vacuum preservation device, which can provide a flexible power supply for a vacuum extraction device, and further provide a refrigerator with the vacuum preservation device.

[0005] The objectives of the present invention can be achieved through the following technical solutions: a vacuum preservation device, comprising at least one vacuum preservation box and a vacuum pumping module, the vacuum preservation box comprising a box body and a box cover, the vacuum pumping module having an independent power supply, the power supply having a wireless energy receiving device that can accept charging from a wireless charging device, and the vacuum pumping module being detachably connected to the box cover.

[0006] In some embodiments, an exhaust hole is provided on the box cover, and the exhaust hole is located in a first slot on the box cover. The vacuum module is provided with a plug-in portion corresponding to the first slot, and the plug-in portion is provided with an exhaust hole connected to the vacuum pump. When the plug-in portion is connected to the first slot, the exhaust hole is connected to the exhaust hole.

[0007] In some embodiments, a wireless charging module for charging the power supply is further included, and the wireless charging module has a power supply for providing wireless energy.

[0008] In some embodiments, the wireless charging module includes a power transmission coil, a positioning protrusion is provided on the wireless charging module corresponding to the power transmission coil, and a positioning groove corresponding to the positioning protrusion is provided on the vacuum module, and the positioning groove corresponds to the power receiving coil of the wireless energy receiving device. The positioning protrusion and the positioning groove cooperate to realize the detachable connection between the wireless charging module and the vacuum module.

[0009] In some embodiments, two parallel vacuum preservation boxes are included, and the vacuum modules corresponding to the two vacuum preservation boxes are connected through a connector, and the opposite sides of the two vacuum modules are provided with the power receiving coils of the wireless energy receiving module, and a wireless charging module is detachably inserted on the connector, and power transmission coils corresponding to the power receiving coils on the two vacuum modules are respectively provided on both sides of the wireless charging module.

[0010] In certain embodiments, the vacuum module and the connector are detachably connected.

[0011] In some embodiments, a button for controlling the operation of the vacuum pump in the vacuum module is provided at the end of the vacuum module.

DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention, which are further described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the inventions involved in the claims. In addition, not all combinations of features described in the embodiments are necessarily required for the solutions of the invention.

[0034] Those skilled in the art will appreciate that all directional references (e.g., above, below, upward, upper, downward, lower, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to aid the reader's understanding and are not intended to limit the scope of the invention as defined by the appended claims (e.g., to position, orientation, or use, etc.). In addition, some vague terms (e.g., substantially, certain, approximately, etc.) may refer to slight inaccuracies or slight deviations in conditions, amounts, values, or dimensions, some of which are within manufacturing deviations or tolerances.

[0035] Example 1

[0036] like Figure 1 、 2As shown in Figures 3, 4, and 5, a vacuum preservation device includes at least one vacuum preservation box and a vacuum module 17. The vacuum preservation box includes a box body 2 and a box cover 21. A sealing ring 22 is provided between the box cover 21 and the box body 2. The vacuum module 17 has an independent power supply 1711, such as a rechargeable lithium battery. The power supply 1711 has a wireless energy receiving device that can be charged by a wireless charging device. The wireless energy receiving device includes a charging control circuit 1713 and a power receiving coil 1712 for receiving wireless electromagnetic energy. The vacuum module 17 is detachably connected to the box cover 21, so that the vacuum module 17 can be charged separately without affecting the use of the vacuum preservation box and without leaving the refrigerator. When the power supply 1711 on the vacuum module 17 is fully charged, it can be connected to the box cover 21 to continue to vacuum the vacuum preservation box. Specifically, this embodiment adopts that the box cover 21 is provided with an exhaust hole 212, and the exhaust hole 212 is located in the first slot 211 on the box cover 21, and the first slot 211 is a triangular slot inclined relative to the box cover 21, and the vacuum module 17 is provided with a triangular plug-in portion corresponding to the first slot 211, and the plug-in portion is provided with an exhaust hole 127 connected to the vacuum pump 1232. When the plug-in portion is connected to the first slot 211, the exhaust hole 127 is connected to the exhaust hole 212, so that the shell can be vacuumed. The first slot 211 and the plug-in portion realize a convenient and detachable connection between the vacuum module 17 and the box cover 21. Of course, other connection methods that are convenient for detachable connection can also be adopted, such as plugging between the exhaust hole 127 and the exhaust hole 212.

[0037] like Figure 6 、 7 As shown in FIG8 , the wireless charging module 18 further includes a wireless charging module 18 for charging the power supply 1711. The wireless charging module 18 has a power supply 1813 for providing wireless energy. When the wireless charging module 18 is placed on the vacuum module 17, the power transmission coil 181 of the wireless charging module 18 that transmits electromagnetic energy corresponds to the power receiving coil 1712 of the vacuum module 17. The power supply 1813 in the wireless charging module 18 is used to charge the power supply 1711. In this way, the vacuum module 17 does not need to be separated from the box cover 21, thereby not affecting the vacuuming operation of the fresh-keeping box and preventing vacuum leakage. The power supply 1813 is, for example, a rechargeable lithium battery and also includes a power supply control circuit 1812 that controls the operation of the power transmission coil 181.

[0038] To facilitate stable charging, the vacuum module 17 and the wireless charging module 18 are detachably connected. Specifically, a circular positioning protrusion 182 is provided on the wireless charging module 18 corresponding to the power transmission coil 181 on the vacuum module 17. A circular positioning groove 1722 corresponding to the positioning protrusion is provided on the vacuum module 17. The positioning groove 1722 corresponds to the power receiving coil 1712 of the wireless energy receiving device. The positioning protrusion can be snapped into the positioning groove 1722, thereby achieving a stable connection between the wireless charging module 18 and the vacuum module 17 and facilitating disassembly. At the same time, because the power transmission coil 181 corresponds to the positioning protrusion and the positioning groove 1722 corresponds to the power receiving coil 1712, the power transmission coil 181 is ensured to correspond to the power receiving coil 1712. Of course, the vacuum module 17 and the wireless charging module 18 can also be conveniently connected and disconnected through other detachable structures.

[0039] Furthermore, a button 123 is provided at the end of the vacuum module 17 to control the operation of the vacuum pump 1232 in the vacuum module 17, so as to control the vacuuming operation in the box body 2. An indicator light 1721 is also provided on the vacuum module 17 above the button 123 to indicate the charging status.

[0040] Example 2

[0041] like Figure 9 、 10 As shown in Figures 11, unlike the above-mentioned embodiment, the vacuum preservation device includes two parallel vacuum preservation boxes. The vacuum modules 17 corresponding to the two vacuum preservation boxes are connected by a connector. The opposite sides of the two vacuum modules 17 are provided with a receiving coil 1712 of the wireless energy receiving module. The connector is detachably inserted with a wireless charging module 18. The two sides of the wireless charging module 18 are respectively provided with a power transmission coil 181 corresponding to the receiving coil 1712 on the two vacuum modules 17. The connector of this embodiment is the positioning plate 1 described in the first embodiment. The plate between the two vacuum modules 17 is provided with a socket. The wireless charging module 18 is detachably inserted into the socket to achieve simultaneous charging of the two vacuum modules 17 on its left and right. This can reduce the required number of vacuum modules 17. The wireless charging module 18 is provided on the plate between the two vacuum modules 17, making the device structure compact.

[0042] like Figure 12As shown, when the vacuum preservation device is used in conjunction with a refrigerator, it is arranged on the inner side of the refrigerator door 4. The inner side of the refrigerator door 4 is provided with a support plate 3 for carrying the vacuum preservation box. A positioning plate 1 is provided above the vacuum preservation box. The vacuum preservation box is located between the support plate 3 and the positioning plate 1. The positioning plate 1 is provided with a second slot 101 for inserting the vacuum module 17. The side of the vacuum module 17 is provided with a guide groove 173 that is convenient for connecting with the second slot, so that the vacuum module 17 can be detachably inserted into the positioning plate 1, so that the two can be detachably connected, so that the vacuum module 17 can be removed for charging or inserted for connection with the vacuum preservation box to achieve vacuumization. In this embodiment, two vacuum preservation boxes are arranged side by side between the support plate 3 and the positioning plate 1, and two vacuum modules 17 are plugged into the corresponding positioning plate 1. In this way, the two vacuum preservation boxes can be fixed at the same time, which has a compact structure and saves space.

[0043] Furthermore, a clamping portion 301 is provided on both sides of the supporting plate 3 and the positioning plate 1, and a stopping portion 401 that cooperates with the clamping portion 301 is provided on the refrigerator door 4, so that the supporting plate 3 and the positioning plate 1 can cooperate with the detachable clamping portion 301 to realize the detachable connection between the supporting plate 3 and the refrigerator door 4. The stopping portion 401 includes a plurality of stopping portions arranged up and down relative to the positioning plate 1. In this way, by adjusting the combination of the supporting plate 3 and the stopping portions 401 of different heights, the distance between the supporting plate 3 and the positioning plate 1 can be adjusted to adapt to vacuum preservation boxes of different heights.
