Description

Technical Field

[0001] This invention relates to a method for interaction between a vacuum assembly and a refrigerator. Background Technology

[0002] As people's living standards improve, they pay great attention to the freshness of food. Vacuum storage is highly popular because it effectively preserves food, extends its shelf life, and increases its utilization value. It is especially useful for storing perishable foods or medicines and biological products that require strict storage conditions; these often require a highly sealed vacuum storage container.

[0003] Currently, vacuum storage boxes or devices for vacuuming storage boxes on the market cannot interact with other household appliances, nor can they track and manage the sealed boxes and the items they contain. In the context of the Internet of Things, they cannot meet the needs of intelligent interaction.

[0004] When the household appliance is a refrigerator, the vacuum storage box is usually simply placed directly in the refrigerator compartment after vacuuming; no connection is established between the refrigerator and the vacuum storage box. Summary of the Invention

[0005] The purpose of this invention is to provide a method for interaction between a vacuum base and a refrigerator, overcoming the existing problems of not being able to interact with other household appliances and lacking intelligence.

[0006] To achieve one of the above-mentioned objectives, a method for interaction between a vacuum assembly and a refrigerator is provided. The vacuum assembly includes a vacuum base and a sealed box that sense each other. The vacuum base includes a first sensing unit and a recognition unit. The sealed box includes a second sensing unit. The refrigerator includes a third sensing unit. The method for interaction between the vacuum assembly and the refrigerator includes: S1, acquiring an image of the sealed box and performing a pre-judgment operation; S2, the pre-judgment operation includes determining whether the item stored in the sealed box needs low-temperature storage based on item information; if so, proceeding to S3; S3, outputting a prompt to place the sealed box in the refrigerator compartment for storage; and S4, placing the sealed box in the refrigerator compartment.

[0007] As an optional technical solution, the operation of acquiring the image of the sealed box in S1 includes:

[0008] Place the sealed box containing the items onto the first surface of the vacuum base;

[0009] The identification unit captures an image of the sealed box; and

[0010] Extract the item images from the image, compare the item images with the item information table, and obtain the corresponding item information.

[0011] As an optional technical solution, S3 also includes recording the item information into the second sensing unit.

[0012] As an optional technical solution, S1 further includes: extracting the image of the sealed box from the image and numbering the sealed box according to the image; and S3 further includes: recording the number into the second sensing unit, so that the number is associated with the item information.

[0013] As an optional technical solution, S3 further includes: determining whether vacuum preservation is required based on the item information; if yes, proceeding to S31; if no, proceeding to S4; wherein, in S31, based on the item information, obtaining the preset vacuum level required for item preservation, and controlling the pump assembly connected to the vacuum base to evacuate the sealed box according to the preset vacuum level.

[0014] As an optional technical solution, S1 or S3 may also include: acquiring the weight information of the items inside the sealed box and recording the weight information in the second sensing unit.

[0015] As optional technical solutions, the following also include:

[0016] S5, control the third sensing unit to sense with the second sensing unit, and the refrigerator obtains the item information and the number recorded in the second sensing unit;

[0017] S6, obtain the location information of the sealed box in the refrigerator; and

[0018] S7. Based on the location information, obtain the actual temperature in the compartment where the sealed box is located, and determine whether the actual temperature is consistent with the preset storage temperature in the item information; if not, proceed to S8.

[0019] S8, adjust the actual temperature of the compartment to match the preset storage temperature, or prompt the user to place the sealed box back into another compartment where the actual temperature matches the preset storage temperature.

[0020] As an optional technical solution, a position sensor is also included, which is installed in a shelf or drawer in the room, and the position sensor and the second sensing unit sense and obtain position information.

[0021] As an optional technical solution, S7 also includes: adjusting the actual humidity in the refrigerator compartment to match the preset humidity information based on the preset humidity information in the item information.

[0022] As an optional technical solution, the first sensing unit, the second sensing unit, and the third sensing unit are all NFC chips.

[0023] Compared with existing technologies, this invention proposes an interaction method between a vacuum component and a refrigerator. By sensing the vacuum base of the vacuum component and the sealed box, the information of the items in the sealed box obtained by the vacuum base is recorded in the sealed box. Then, the sealed box is sensed by the refrigerator, enabling the refrigerator to obtain the information of the items in the sealed box. Based on the obtained information, the refrigerator manages and tracks the items stored in the sealed box, allowing the refrigerator to more rationally manage and track the status of the items stored therein. This overcomes the problems of existing refrigerators not being able to manage and track the items inside, leading to long-term storage and improper storage conditions. Attached Figure Description

[0039] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0040] like Figure 1 As shown, in one embodiment of the present invention, a vacuum assembly 100 is provided, which includes a vacuum base 10 and a sealing box 20. The vacuum base 10 is used to remove air from the inner cavity of the sealing box 20, so that a vacuum is formed in the inner cavity.

[0041] In a preferred embodiment, the vacuum base 10 and the sealing box 20 are independent of each other and can be sold separately as independent products. That is, both the vacuum base 10 and the sealing box 20 can be used independently. In other words, the vacuum base 10 can be used for vacuuming various other sealing boxes; the sealing box 20 can also be combined with other vacuum bases to achieve the purpose of vacuuming.

[0042] like Figures 1 to 4 As shown, the vacuum base 10 includes a housing 11. A suction structure is provided on the top surface of the housing 11, and the suction structure is interconnected with the inner cavity 110 of the housing 11. An external suction port 14 is also provided on the housing 11, which is connected to both the inner cavity 110 and the suction pipeline of a pump assembly (not shown). Air in the inner cavity 110 is discharged through the external suction port 14 and the suction pipeline, forming a vacuum. The external suction port 14 can be located at any position on the housing 11. In this embodiment, the external suction port 14 is located on the side of the housing 11, surrounding the top surface and extending towards the bottom surface 114 of the housing 11. The top and bottom surfaces 114 are positioned opposite each other.

[0043] It should be noted that the top surface and bottom surface 114 refer to the horizontal position of the vacuum base 10. When the vacuum base 10 is placed vertically, the top surface can be the front surface facing the user, and the bottom surface 114 can be the rear surface away from the user.

[0044] like Figure 1 As shown, the top surface includes a first surface 111 and a second surface 112 arranged at an angle, with the included angle between the first surface 111 and the second surface 112 being between 0 and 180°. In this embodiment, the included angle between the first surface 111 and the second surface 112 is an obtuse angle, that is, the second surface 112 extends obliquely upward from one side of the first surface 111.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown, an air extraction structure is provided on the first surface 111. The air extraction structure is located in the middle area of ​​the first surface 111. Even if there is a placement deviation of the sealing box 20 on the first surface 111, it will not affect the vacuuming effect of the vacuum base 10.

[0046] The air extraction structure includes a recess 15, a cap 12, and a sealing gasket 13 formed on a first surface 111. Both the cap 12 and the sealing gasket 13 are located in the recess 15. The cap 12 has an extension 121, and the sealing gasket 13 has an opening facing the extension arm. A step 131 is provided in the opening. The groove of the sealing gasket 13 engages with the sidewall of the recess 15. The cap 12 is inserted into the opening of the sealing gasket 13, and the extension 121 and the step 131 are in contact with each other, preferably in an elastic abutment, to prevent the cap 12 from coming out of the opening of the sealing gasket 13.

[0047] The sealing gasket 13 is also provided with a through hole 132, which is located at the bottom of the sealing gasket 13, opposite to the opening, and protruding into the inner cavity 110 of the housing 11. The through hole 132 connects to the inner cavity 110, and the inner cavity 110 connects to the external air extraction port 14.

[0048] like Figure 3 and Figure 4 As shown, a plurality of spaced-apart extension arms 121 extend from the cap 12, and there are gaps 122 between the spaced-apart extension arms 121. That is, the cap 12 has gaps 122.

[0049] In a preferred embodiment, the top surface of the cap 12 protrudes from the top surface of the sealing gasket 13. Preferably, the top surface of the cap 12 is slightly higher than or flush with the first surface 111. The top surface of the cap 12 protrudes from the top surface of the sealing gasket 13, such that the gap 122 has a portion protruding from the top surface of the sealing gasket 13, facilitating the flow of air from the gap 122 toward the through hole 132.

[0050] In addition, there is a gap between the edge of the cap 12 and the inner side of the first recess 115, which facilitates the smooth passage of air through the gap 122, the through hole 132, the inner cavity 110 and the external air extraction hole 14 during vacuuming and its extraction by the pump assembly.

[0051] In a preferred embodiment, the cap 12 and the sealing gasket 13 are both made of elastic materials such as silicone or rubber.

[0052] like Figure 1 and Figure 3 As shown, the first surface 111 and the second surface 112 are arranged at an obtuse angle, for example. An identification unit 13 is provided on the side of the second surface 112 facing the first surface 111. The identification unit 13 is used to identify the items stored in the sealed box 20 to be vacuumed and placed on the first surface 111.

[0053] In this embodiment, the angle between the first surface 111 and the second surface 112 is an obtuse angle, and the identification unit 13 is provided on the side of the second surface 112 facing the first surface 111, so that the identification unit 13 is always facing the sealed box 20 placed on the first surface 111. That is, as long as the sealed box 20 is placed on the first surface 111, the identification unit 13 can successfully obtain the items and related information stored in the sealed box 20.

[0054] It should be noted that when the identification unit 13 obtains the items and related information stored in the sealed box 20, the sealed box 20 is, for example, a transparent box, and the outer packaging of the items inside the sealed box 20 has been removed.

[0055] In a preferred embodiment, the identification unit 13 is, for example, a camera module, which includes a camera and an image processing unit. The camera captures an image of the sealed box 20, and the image processing unit acquires the image and extracts the image of the item in the image. The vacuum base 10 also includes a control unit, which is electrically connected to the camera module. After acquiring the image of the item, the control unit compares it with the item information table in the storage unit of the vacuum base 10 to obtain the item information. Based on the item information, it determines whether the item in the sealed box 20 can be vacuum preserved. The control unit controls the vacuum base 10 to output voice and text prompts to inform the user of the item information and whether it is suitable for vacuum preservation.

[0056] In addition, the vacuum base 10 may also include a wireless or wired communication module, that is, the vacuum base 10 can access the Internet or the cloud via a data cable or Wi-Fi. Taking the identification unit 13 as a camera module as an example, the camera captures an image of the sealed box 20, the image processing unit acquires the image and extracts the image of the item in the image, the control unit compares it with the item information table in the storage unit, when no information similar to the item image is found in the item information table, the control unit controls the wireless or wired communication module to start, so as to query the information of the item that is the same as the item in the item image, and determine whether the corresponding item can be vacuum preserved, and then controls the voice unit or display unit of the vacuum base 10 to output voice and text prompts to inform the user of the item information and whether it is suitable for vacuum preservation.

[0057] Of course, if the control unit determines that the items in the sealed box (such as fresh vegetables, fresh fruits, etc.) are not suitable for vacuum preservation, the control unit controls the voice unit or display unit to output voice, text or a combination thereof to prompt the user. Furthermore, it outputs a control signal to control the vacuum pump assembly to be in an unstartable state.

[0058] If the control unit determines that the items in the sealed box (such as meat, dairy products, etc.) are suitable for vacuum preservation, the control unit outputs voice, text or a combination thereof to prompt the user. Furthermore, it outputs a control signal to control the vacuum pump assembly to be in an startable state. When the pump assembly is started, the sealed box 20 can be vacuumed through the vacuum base 10.

[0059] In addition, based on the images captured by the identification unit 13, the control unit obtains the following item information: item name, item category (raw food, cooked food, medicine, etc.), required vacuum level for preservation, shelf life, and storage temperature (low-temperature storage, room temperature storage, etc.).

[0060] In one embodiment of the invention, this item information can be printed into item labels using a printing device, which the user then affixes to the sealed box 20. The printing device can be integrated inside the vacuum base 10, or the vacuum base 10 can be connected to an external printer for printing. The item labels can be, for example, paper labels, but are not limited thereto.

[0061] In another embodiment of the present invention, this item information can be transmitted from the NFC chip of the vacuum base 10 to the NFC chip inside the sealed box 20. That is, the item information can be stored in the NFC chip inside the sealed box 20. When the sealed box 20 is placed in a household appliance, such as a refrigerator, the NFC chip inside the sealed box 20 can continue to interact with the NFC chip of the household appliance, facilitating the household appliance's management of the sealed box. In other words, the vacuum component 100 provided by the present invention interacts with the sealed box 20 through the vacuum base 10, using the sealed box 20 as a carrier of item information, and continues to interact with household appliances, making the application of the vacuum component 100 more intelligent and improving the user experience.

[0062] In a preferred embodiment, the vacuum base 10 also includes a reset button. When the items stored in the same sealed box 20 are changed, the reset button is turned on to re-identify the items in the sealed box 20 and update the new item information.

[0063] It should be noted that after the camera of the identification unit 13 of the vacuum base 10 captures the image information of the sealed box and the item, the image processing unit can also acquire the image of the sealed box. The control unit acquires the image of the sealed box and assigns a number to the sealed box 20 currently placed on the vacuum base 10. The number can be printed out through the item label, or transmitted through the NFC chip of the vacuum base 10 and recorded in the NFC chip of the sealed box 20. The number is then associated with the corresponding item information.

[0064] like Figure 14 As shown, in other embodiments of the present invention, a method for interaction between the vacuum base 10 and the sealed box 20 is also provided, including:

[0065] S101, Obtain the first image of the sealed box;

[0066] S102, Extract the first item image from the first image and output the first item information;

[0067] S103, based on the first item information, determine whether the item needs to be vacuum preserved; if so, proceed to S104.

[0068] S104, based on the preset vacuum level in the first item information, the sealing box is evacuated by the pump assembly according to the preset vacuum level.

[0069] In a preferred embodiment, S102 also includes an NFC chip that records item information to the sealed box.

[0070] In a preferred embodiment, S102 further includes extracting the image of the sealed box from the first image, numbering the sealed box according to the image, and recording the number into the NFC chip of the sealed box, so that the number is associated with the corresponding first item information.

[0071] In a preferred embodiment, S102 further includes a storage unit for recording the number and corresponding first item information to the vacuum base.

[0072] In a preferred embodiment, it further includes:

[0073] S105, open the sealed box in S104, take out the items from the sealed box, and put the new items into the same sealed box;

[0074] S106, Place the same sealed box containing the new item on the vacuum base and obtain the second image;

[0075] S107, Extract the image of the sealed box from the second image, obtain the number of the sealed box, and read the first item information corresponding to the number;

[0076] S108, extract the image of the second item from the second image, output the information of the second item, and determine whether the type information of the second item is consistent with the type information in the first item; if yes, proceed to S109; if no, proceed to S110.

[0077] S109, compare the difference information between the second item information and the first item information, update the difference information to the NFC chip of the sealed box, or directly record the second item information to the NFC chip of the sealed box to overwrite the first item information.

[0078] S110, reset the vacuum base 10, causing the vacuum base to re-execute the operations in S101 to S104; and, record the second item information to the NFC chip of the sealed box, overwriting the first item information.

[0079] The item number is associated with the information of the second item.

[0080] Furthermore, this includes updating the second item information to the storage unit.

[0081] Furthermore, the method by which the sealed box 20 interacts with home appliances using an NFC chip that stores information about the items will be described in detail in the section on the interaction method between the vacuum assembly and the refrigerator.

[0082] In a preferred embodiment, after the control unit of the vacuum base 10 obtains the item information, it can control the vacuum level in the sealed box 20 extracted by the pump assembly, such as a low vacuum state or a high vacuum state, based on the required vacuum level information stored in the item information. In this embodiment, the vacuum level can be read from the pressure gauge on the pump assembly.

[0083] In a preferred embodiment, the vacuum base 10 also includes a time module that can communicate with the control unit. When the identification module 13 takes a picture of the items inside the sealed box 20, and the control unit determines that the items are suitable for vacuum preservation, the sealed box 20 is evacuated, the time module is activated, and the initial preservation date is recorded, which facilitates the subsequent user's determination of the preservation period of the items inside the sealed box 20.

[0084] When the vacuum base 10 outputs a paper label, the initial storage date and the longest storage date can be printed on the paper label and affixed to the outside of the sealed box 20.

[0085] When the item information obtained by the vacuum base 10 is transmitted and recorded in the NFC chip inside the sealed box 20 via the NFC chip, the initial storage date and the maximum storage date are recorded in the NFC chip inside the sealed box 20 along with other item information.

[0086] In a preferred embodiment, the sealed box 20 includes a display unit electrically connected to an NFC chip, wherein the item information recorded in the NFC chip can be displayed on the display unit, making it easier for users to understand the item information more intuitively.

[0087] In a preferred embodiment, the vacuum base 10 further includes a weighing module, which can be used to weigh the weight of the items stored in the sealed box 20. The weighing method includes, but is not limited to, placing the sealed box 20 on the first surface 111, zeroing it, placing the items into the sealed box 20, and weighing the items placed inside.

[0088] In a preferred embodiment, the vacuum base 10 further includes a voice module. In a first prompt mode, the voice module outputs only usage information for the vacuum base 10; in a second prompt mode, the voice module outputs only usage information for the sealed box 20. The first prompt mode refers to various usage states where the sealed box 20 is not placed on the vacuum base 10; the second prompt mode refers to providing usage information for the sealed box 20 after it has been placed on the vacuum base 10.

[0089] like Figure 1 , Figure 2 and Figure 4 As shown, a gravity sensor (not shown) is installed in the vacuum base 10. The gravity sensor is used to sense the placement state of the vacuum base 10. The placement state of the vacuum base 10 includes at least horizontal placement and vertical placement. When horizontally placed, the bottom surface 114 contacts the placement platform; when vertically placed, either side between the bottom surface 114 and the top surface can contact the placement platform.

[0090] In this embodiment, the first side surface 113 is located on the side of the first surface 111 away from the second surface 113 and connected to the side surface of the bottom surface 114. Anti-slip pads 16 are respectively provided on the bottom surface 114 and the first side surface 113. The anti-slip pads 16 are used to prevent the vacuum base 10 from shaking when placed horizontally or vertically.

[0091] In a preferred embodiment, the gravity sensor and the control unit are electrically connected (or can transmit data). After the gravity sensor senses the position of the vacuum base, the control unit obtains the corresponding position and controls the corresponding functional module to start.

[0092] Specifically, when the gravity sensor detects that the vacuum base 10 is in a first placement state, such as a horizontal placement state, the control unit controls the vacuum base 10 to enter a first usage mode, which includes the recognition mode and / or vacuuming mode. The control unit then prompts the user via a voice module about the currently available functions of the vacuum base 10 and the specific operating procedures for those functions. Furthermore, when the sealing box 20 is placed on the first surface 111 of the top surface of the vacuum base 10, the voice module can output relevant voice prompts regarding the usage status of the sealing box 20.

[0093] When the gravity sensor detects that the vacuum base 10 is in a second placement state, such as an upright placement state, the control unit controls the vacuum base 10 to enter a second usage mode, such as a timer mode, turning off the vacuuming mode. In the timer mode, the user can be prompted with the current date through the voice module.

[0094] In addition, the vacuum base 10 can save space when placed upright, making it easy to store.

[0095] like Figures 3 to 4 As shown, the housing 11 of the vacuum base 10 also includes a second side surface 115. One side of the second side surface 115 is connected to the side of the second surface 112 away from the first surface 111, and the second side surface 115 is connected to the bottom surface 114 through an arc-shaped portion. In this embodiment, a touch screen can be provided on the second side surface 115. The touch screen can display text prompts output by the control unit.

[0096] like Figure 1 , Figures 5 to 11As shown, the sealed box 20 includes a top cover 21, a sealing assembly, a box body 25, and a gasket 26 stacked from top to bottom. The sealing assembly includes an upper partition 22, a lower partition 23, and a sealing ring 24 surrounding the upper partition 22. The sealing assembly seals the opening 258 of the box body 25. The upper partition 22 of the sealing assembly is provided with a first opening 221 and a second opening 229 that penetrate through it. The second opening 229 is connected to the internal storage space of the box body 25. The bottom plate 254 of the box body 25 is provided with an exhaust port 2531. The first opening 221 and the exhaust port 2531 are respectively connected to the air extraction channel 253. When the sealed box 20 is placed on the vacuum base 10, the air in the storage space inside the sealed box 20 flows out through the second opening 229 and enters the vacuum base 10 through the first opening 221, the air extraction channel 253, and the exhaust port 2531, and is then removed by the pump assembly.

[0097] like Figures 6 to 11 As shown, the upper cover 21 includes a cover body 211 and a peripheral first sidewall 212 surrounding the cover body 211. The first sidewall 212 extends toward the sealing assembly and covers the portion of the sealing assembly that protrudes from the top surface 257 of the housing 25. That is, the upper cover 21 closes onto the housing 25, and the end of the first sidewall 212 away from the cover body 211 contacts the portion of the top surface 257 of the housing 25.

[0098] In this embodiment, the end of the first sidewall 212 away from the cover body 211 forms a first joint 2121. The first joint 2121 is an inverted L-shaped structure. The inverted L-shaped structure covers the protrusion 243 of the sealing ring 24 and contacts the top surface 257 of the part.

[0099] A vent button 27 is provided on the upper side of the cover body 211. The vent button 27 also includes a first sealing post 272, one end of which is fixedly connected to the vent button 27. A vent hole 271 penetrates the cover body 211. When the vent button 27 is in the closed state, the first sealing post 272 on the button 27 fills the vent hole 271. The lower side of the cover body 211 faces the upper partition 22.

[0100] In this embodiment, the first sealing post 272 is preferably made of a soft or elastic material, such as silicone or rubber. When the first sealing post 272 is inserted into the vent hole 271, it can maintain a good seal with the vent hole 271, and there will be no air leakage during the vacuuming process, thus ensuring good sealing performance.

[0101] In a preferred embodiment, the vent button 27 is rotatably connected to the cover body 211 via a rotating part 273, wherein the rotating part 273 and the first sealing post 272 are respectively located on the side of the vent button 27 facing the upper partition 22, and are distributed at opposite ends of the vent button 27. The rotating part 273 is, for example, a conical protrusion.

[0102] In a preferred embodiment, the cover body 211 has a plurality of positioning protrusions 214 on the side facing the upper partition 22. The plurality of positioning protrusions 214 protrude toward the upper partition 22 and pass through the positioning recesses 225 in the upper partition 22, facilitating the alignment and assembly of the upper cover 21 and the sealing assembly. In addition, the positioning protrusions 214, passing through the positioning recesses 225, together with the filling pillars 228 in the positioning recesses 225, seal the positioning recesses 225 to prevent air leakage, that is, gas will not flow out or in from the positioning recesses 225.

[0103] In a preferred embodiment, the cover body 211 is further provided with a receiving hole 213, and the sealing button 28, which is attached to the upper side of the upper partition 22, is received in the receiving hole 213 and protrudes from the receiving hole 213, so that the user can open or close the sealing button 28.

[0104] like Figures 6 to 11 As shown, in the sealing assembly, the sealing ring 24 surrounds the upper partition 22, and the upper partition 22 has a second recess 222. The sealing button 28 is rotatably mounted in the second recess 222. The sealing button 28 includes a second sealing post 281, and a second opening 229 is located in the second recess 22. When the sealing button 28 is in the closed state, the second sealing post 281 is inserted into the second opening 229; when the sealing button 28 is in the open state, the second sealing post 281 is pulled out of the second opening 229 to release the vacuum, facilitating the removal of the upper cover 21 and the sealing assembly from the opening 258 at the top of the housing 25.

[0105] like Figure 8 and Figure 9 As shown, the sealing button 28 also includes a rotating arm 282 and a rotating shaft 283. The rotating shaft 283 is fixed in the second recess 222, and the rotating arm 282 is connected to the rotating shaft 283, so that the sealing button 28 rotates around the rotating shaft 283, thereby allowing the second sealing post 281 to be inserted into or removed from the second opening 229.

[0106] like Figure 6 , Figure 8 and Figure 9 As shown, the upper partition 22 also includes a second sidewall 223 protruding toward the lower partition 24. A groove 224 is formed on the outer surface of the second sidewall 223, and a sealing ring 24 is embedded in the groove 224. In addition, a plurality of engaging protrusions 226 are formed on the inner surface of the second sidewall 223. An engaging groove 232 protrudes toward the upper partition 22 from the edge of the lower partition 23. The engaging groove 232 engages with the engaging protrusions 226, so that the lower partition 23 and the second sidewall 223 of the upper partition 22 are engaged and connected to each other.

[0107] In this embodiment, the periphery of the lower partition 23 contacts the inner side surface of the second side wall 223.

[0108] like Figures 7 to 9 As shown, the sealing ring 24 has a protrusion 241 on the side facing the box body 25, and the protrusion 241 is embedded in the upper end of the air extraction channel 253.

[0109] Corresponding to the protrusion 241, the upper partition 22 is provided with a first clearance part 227, and the lower partition 23 is provided with a second clearance part 233. The protrusion 241 passes through the first clearance part 227 and the second clearance part 233 and gets stuck into the upper end of the air extraction channel 253.

[0110] A third opening 242 is provided in the protrusion 241, and the third opening 242 is connected to the first opening 221.

[0111] In addition, there is a gap space 243 between the top of the third opening 242 and the bottom of the first opening 221. The bottom of the first opening 221 of the upper partition 22 extends into the gap space 243. While maintaining the interconnection between the first opening 221, the protrusion 241 and the air extraction channel 253, it can also ensure that the upper partition 22, the sealing ring 24 and the air extraction channel 253 can maintain good sealing performance during vacuuming to avoid air leakage.

[0112] like Figure 6 and Figure 7 As shown, the lower partition 23 includes multiple slots 231, and the multiple cuts 231 penetrate the lower partition 23, thereby enabling the storage space inside the box 25 to communicate with the second opening 229 on the upper partition 22.

[0113] like Figures 6 to 9 As shown, the air extraction channel 253 is located in the storage space of the box 25. The pipe wall 252 of the air extraction channel 253 is connected to the inner wall surface 251 of the box 25. The pipe wall 252 is roughly U-shaped, and the opening of the U-shaped structure faces the inner wall surface 251.

[0114] It should be noted that the shape of the pipe wall is not limited to U-shape or C-shape.

[0115] In this embodiment, the space between the pipe wall 252 and the inner wall surface 251 is the air extraction channel 253.

[0116] Preferably, the top end of the suction channel 253 engages with the protrusion 241 of the sealing ring 24; the bottom outlet of the suction channel 253 is the exhaust port 2531. The bottom outlet of the suction channel 252 extends and penetrates the bottom plate 254 of the box 25, so that the exhaust port 2531 penetrates the bottom plate 254.

[0117] like Figures 7 to 9As shown, the bottom plate 254 of the box 25 protrudes into the mounting groove 255 of the gasket 26. The mounting groove 255 is arranged around the periphery of the bottom plate 254. The gasket 26 includes an upper protrusion 261 and a lower gasket 262. The upper protrusion 261 is embedded in the mounting groove 255 to assemble the gasket 26 with the box 25. The lower gasket 262 contacts the first surface 111 of the vacuum base 10. The lower gasket 262 extends toward the outer edge of the gasket 26, so that it can be better adsorbed on the first surface 111, maintaining the sealing state between the gasket 262 and the bottom plate 254, that is, ensuring the vacuum degree between the sealed box 20 and the vacuum base 10.

[0118] In this embodiment, the washer 26 is adapted to the shape of the base plate 254, for example, it is rectangular, but not limited thereto. In other embodiments of the present invention, the washer may also be circular, elliptical, polygonal, or other shapes.

[0119] In addition, the gasket 26 is preferably made of soft or elastic materials such as silicone or rubber to improve the sealing reliability when it comes into contact with the vacuum base 10.

[0120] The following will be illustrated with the accompanying drawings. Figures 1 to 11 Explain the gas flow path during the vacuum assembly 100's vacuuming process.

[0121] The sealed box 20 is placed on the first surface 111 of the vacuum base 10. The sealing button 28 and the venting button 27 are closed. The pump assembly is turned on, which generates negative pressure, causing the air in the storage space of the box 25 to flow out of the storage groove 231 and the second opening 229, enter the air extraction channel 253 through the first opening 221 and the third opening 242, and be discharged from the exhaust port 2531 into the gap 122 in the first surface 111 of the vacuum base 10, and then through the through hole 132 and the inner cavity 110; finally, it is discharged from the external air extraction port 14, thus realizing the vacuuming of the sealed box 20.

[0122] like Figure 10 and Figure 11 As shown, after the pump assembly starts, it generates a large suction force. This force attracts the second sealing post 281 of the sealing button 28 inserted into the second opening 229, causing it to lift slightly and creating a small gap. This allows the airflow in the storage space of the housing 25 to flow outward. In other words, after the pump assembly starts, the second opening 229 and the sealing button 28 form a one-way valve.

[0123] After the vacuuming is completed, the pump assembly stops working. Since the function of attracting the second sealing post 281 is removed, the second sealing post 281 is reinserted into the second opening 229, and the housing 25 is resealed.

[0124] Additionally, when it is necessary to remove the sealed box from the first surface 111, the venting button 27 is opened, the first sealing post 272 is pulled out from the venting port 271, and air enters from the venting port 271 between the cover body 211 and the upper partition 22 of the upper cover 21, and then enters from the first opening 221, the third opening 242, the air extraction channel 253 and the exhaust port 2531 into the space between the bottom plate 254 and the first surface 111 of the box body 25, removing the vacuum adsorption between the bottom plate 254 and the first surface 111, and the sealed box 20 can be smoothly removed from the first surface 111.

[0125] Since the sealing button 28 is integrated into the second opening 229, the process of releasing the air from the sealing box 20 does not affect the vacuum level of the box 25, giving the sealing box 20 the advantage of being less prone to leakage.

[0126] In a preferred embodiment, the sealed box 20 further includes a filter membrane (not shown), which is disposed at the bottom end of the second opening 229 and is used to filter water vapor and oxygen in the air inside the box 25. That is, water vapor and oxygen can pass through the filter membrane and be extracted by the pump assembly, but nitrogen and inert gases in the air are retained in the storage space inside the box 25, ensuring that the items stored in the box 25 are in a nitrogen and inert gas environment, which helps to extend the shelf life of the sealed box 20.

[0127] In addition, for special items that need to be stored in an environment with a certain humidity, the filter membrane allows gas molecules other than water vapor to pass through. When the pump assembly evacuates, the water vapor remains in the storage space of the box 25 to maintain a suitable humidity environment.

[0128] In addition, the filter membrane can also be placed at the opening 258 of the housing 25, near the lower side of the lower partition 23. Preferably, the filter membrane covers the entire opening 258.

[0129] The present invention also provides a method for interaction between a vacuum component and a household appliance, particularly a method for interaction between the sealed box of the vacuum component and the household appliance, wherein the household appliance is, for example, a refrigerator, preferably a smart refrigerator; it can obtain item information by sensing at least one of the vacuum base 10 and the sealed box 20 of the vacuum component 100, and intelligently manage the items stored in the refrigerator based on the corresponding item information.

[0130] In this invention, the items stored in the sealed box 20 include, but are not limited to, food, medicine, etc.

[0131] like Figure 12As shown, the vacuum assembly 100 includes a vacuum base 10 and a sealed box 20 that sense each other. The vacuum base 10 includes a first sensing unit 30; the sealed box 20 includes a second sensing unit 40 and is used to store items; the refrigerator 200 includes a third sensing unit 50; preferably, the first sensing unit 30 and the second sensing unit 40 sense each other; the second sensing unit 40 and the third sensing unit 50 sense each other; that is, the vacuum base 10 and the sealed box 20 interact, and the sealed box 20 and the refrigerator 200 interact.

[0132] like Figure 13 As shown, the interaction method 300 between the vacuum assembly 100 and the refrigerator 200 includes:

[0133] S1, acquire an image of the sealed box and perform a prediction operation;

[0134] S2, the pre-judgment operation includes determining whether the items stored in the sealed box need to be stored at low temperature based on the item information; if so, proceed to S3;

[0135] S3 outputs a prompt indicating that the sealed box can be placed in the refrigerator compartment for storage; and

[0136] S4. Place the sealed box in the refrigerator compartment.

[0137] In a preferred embodiment, the operation of acquiring an image of the sealed box in S1 includes:

[0138] Place the sealed box onto the first surface of the vacuum base;

[0139] The recognition unit captures an image of the sealed box;

[0140] Extract the item images from the image, compare the item images with the item information table, and obtain the corresponding item information.

[0141] In a preferred embodiment, S3 further includes a second sensing unit that records item information to the sealed box.

[0142] In another preferred embodiment, step S1 further includes: extracting the image of the sealed box from the image, and numbering the sealed box according to the image; step S3 further includes: recording the number into the second sensing unit, so that the number is associated with the item information. This association between the number and the item information facilitates that after the item information in the sealed box is updated, it can still be recognized by the refrigerator's third sensing unit and updated accordingly.

[0143] The sealed box number is associated with the item information. If the items stored in the same sealed box are used or removed, the item information in this sealed box will be updated. At this time, only the item information recorded under the current number needs to be updated, without changing the number.

[0144] In addition, by associating the number of the sealed box with the item information stored inside, and linking the sealed box with household appliances (such as refrigerators), the refrigerator can manage and track the sealed boxes stored in its compartments. That is, by establishing a list of associations between the number and the item information, when the item information recorded under the same number is updated, the item information corresponding to the same number in the list can be updated in a timely manner, which facilitates subsequent management and tracking.

[0145] In yet another preferred embodiment, S3 further includes:

[0146] Based on the item information, determine whether vacuum preservation is required; if yes, proceed to S31; otherwise, proceed to S4.

[0147] S31, based on the item information, obtains the preset vacuum level required for item preservation, and controls the pump assembly to evacuate the sealed box according to the preset vacuum level.

[0148] Additionally, S1 or S3 also includes: acquiring the weight information of the items inside the sealed box and recording the weight information in the second sensing unit. The weight information is one type of item information.

[0149] In this embodiment, the operations in S1 to S3 are all performed in the vacuum base 10.

[0150] The interaction method 300 between the vacuum assembly 100 and the refrigerator 200 in this invention further includes:

[0151] S5, control the third sensing unit to sense with the second sensing unit, and the refrigerator obtains the item information and number recorded in the second sensing unit of the sealed box;

[0152] S6, obtain the location information of the sealed box in the refrigerator; and

[0153] S7. Based on the location information, obtain the actual temperature in the compartment where the sealed box is located, and determine whether the actual temperature is consistent with the preset storage temperature in the item information; if not, proceed to S8.

[0154] S8, adjust the actual temperature of the compartment to match the preset storage temperature, or prompt the user to re-place the sealed box into another compartment with the same actual temperature as the preset storage temperature for storage.

[0155] In this embodiment, the position sensor 60 is disposed in the compartment of the refrigerator. Preferably, the position sensor 60 is located in different shelves or drawers. The position information is obtained by maintaining the sensor 60 in contact with the second sensing unit 40 of the sealed box 20. The position information includes, for example, which shelf of the corresponding compartment, and is recorded in the refrigerator's processing module.

[0156] Furthermore, the location information is linked to the serial number of the sealed container. When the location of a sealed container with the same serial number changes, the second sensor and position sensor of the sealed container re-sensitize it, generate new location information, and re-upload it to the refrigerator's processing module. Recording location information helps users find their target items more quickly. Specifically, users can input the item they need to retrieve on the refrigerator's touchpad, and the processing module automatically tracks its location and indicates the location of the sealed container where the item was stored, saving time.

[0157] In a preferred embodiment, step S7 further includes: adjusting the actual humidity in the refrigerator compartment to match the preset humidity information based on preset humidity information in the item information. The actual humidity in the compartment can be measured by a humidity sensor installed inside the compartment.

[0158] Additionally, if the actual humidity in the current compartment differs significantly from the preset humidity information, the user will be prompted to relocate the sealed box to another compartment with the same actual humidity and preset storage temperature for storage.

[0159] In this embodiment, the item information includes, but is not limited to, item name, item category, item weight, item storage temperature, item storage vacuum level, item storage ambient humidity, and item storage period (including start date and end date).

[0160] In this embodiment, the first sensing unit 30, the second sensing unit 40, and the third sensing unit 50 are NFC chips.

[0161] In one embodiment of the present invention, the item information recorded in the second sensing unit 40 may be temporarily stored in the first sensing unit 30. The second sensing unit 40 and the first sensing unit 30 transmit data, so that the item information temporarily stored in the first sensing unit 30 is recorded in the second sensing unit 40.

[0162] In addition, the refrigerator includes a timing module that activates after the sealed container 20 is placed in the compartment. For items with short shelf lives (fresh milk, yogurt), it prompts the user to use them as soon as possible 24-48 hours before the preset storage date, and prompts the user to remove and discard them from the refrigerator as soon as the preset storage date is reached. The prompts can be made by playing voice messages, displaying text, or a combination thereof.

[0163] The timing module stops timing the corresponding sealed box 20 on the day when the stored item reaches the preset storage period, and resets the timing module until the stored item information in the same sealed box 20 is updated, at which point it restarts timing the storage time of the same sealed box 20.

[0164] This invention also provides a method for updating item information stored in the sealed box 20. The method for updating item information is mainly achieved through the interaction between the vacuum base 10 and the sealed box 20. Specifically:

[0165] S1000: Remove the sealed box that was placed in the refrigerator in S4 from the refrigerator compartment and record the number of the removed sealed box.

[0166] S2000, open the sealed box, take out the items from the sealed box, obtain an empty sealed box, and put in new items;

[0167] S3000: Place the sealed box containing the new item on the vacuum base and determine whether to activate the reset button of the vacuum base; if yes, proceed to S4000; if no, proceed to S5000.

[0168] S4000, reset the vacuum base to repeat the process from S1 to S3 above, obtain updated item information, and record the updated information in the second sensing unit;

[0169] S5000, re-weighs the new item, and the updated weight information is recorded in the second sensing unit; and

[0170] S6000: Place the sealed box from S3000 or S4000 into the refrigerator, control the second and third sensing units to sense, and update the item information recorded under the number in S1000.

[0171] In this embodiment, if the new item in S3000 is a different item from the original item, it is determined that the reset button of the vacuum base needs to be activated to enter S4000; if the new item in S3000 is only a change in weight caused by the use of an item taken out of the sealed box, it is determined that the reset button of the vacuum base does not need to be activated to enter S5000.

[0172] In summary, this invention proposes an interaction method between a vacuum component and a refrigerator. The vacuum component's base senses the sealed box, recording the information about the items inside. The sealed box is then sensed by the refrigerator, allowing the refrigerator to obtain the information about the items inside. Based on this information, the refrigerator manages and tracks the items stored in the sealed box, enabling more efficient management and tracking of the stored items. This overcomes the limitations of existing refrigerators that cannot manage and track items, leading to problems such as long-term storage and improper storage conditions.
