[0002] Food is prone to spoilage, rotting, or loss of freshness, and often needs to be placed in the refrigerator to maintain its freshness through various functions. Different foods require different storage conditions. However, the functions provided by the refrigerator's crisper drawer in the current technology are relatively simple and cannot be adjusted to suit different storage environments. Summary of the Invention

[0003] This application provides a food preservation component, a ventilation component, and a refrigerator, which can provide corresponding functional modules to meet the different needs of different foods for preservation environment, and achieve targeted environmental adjustment of the food preservation box to achieve the best food storage environment and extend the food preservation period.

[0004] To address the aforementioned technical problems, this application provides a preservation component, which includes a connecting mechanism and a first annular box. The connecting mechanism has an air duct. The first annular box is arranged around the connecting mechanism and includes a plurality of first arc-shaped boxes and a plurality of first functional modules disposed within the plurality of first arc-shaped boxes. Different first functional modules are used to provide different preservation functions. The first annular box is rotatable around the connecting mechanism, such that the air duct connects two of the first arc-shaped boxes, and can be used to allow air to pass through the air duct and the corresponding first functional modules within the two first arc-shaped boxes.

[0005] To solve the above-mentioned technical problems, this application provides a ventilation component, which includes a substrate and a preservation component; wherein, the substrate has a mounting groove and a ventilation channel passing through the mounting groove; the preservation component is disposed in the mounting groove, and the preservation component is the aforementioned preservation component.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] In the description of this application, it should be understood that the orientations or positional relationships indicated by terms such as "center," "middle," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" are based on the orientations and positional relationships shown in the accompanying drawings and are used merely for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] The inventors of this application have discovered through research that existing air-cooled refrigerator crisper drawers have relatively simple functional modules, only able to accommodate one or combine with other functions to form a fixed functional mode. They cannot provide targeted or precise adjustments to the storage environment for different foods, thus failing to meet users' high standards for refrigerator preservation quality and significantly diminishing the user experience. To solve these technical problems, this application provides the following technical solutions.

[0025] like Figure 1 As shown, one embodiment of this application provides a refrigerator 1, including a refrigerator body 10 and a ventilation assembly 20. The refrigerator body 10 has a food preservation box 15 for preserving food. The ventilation assembly 20 is used to ventilate the food preservation box 15 to provide different storage conditions tailored to the type of food.

[0026] The refrigerator body 10 generally includes at least one of the following: a freezer compartment 11, a refrigerator compartment 12, a fresh food compartment 13, and a variable temperature compartment 14. The freezer compartment 11 can be used to store fresh or frozen meat, fish, and poultry, as well as cooked food. The temperature of the freezer compartment 11 is approximately -18°C, with a shelf life of about 3 months. The freezer compartment 11 can quickly freeze fresh fish and meat that need to be stored for a long time to maximize the freshness and flavor of the food. The refrigerator compartment 12 can be used to refrigerate raw and cooked foods. The temperature of the refrigerator compartment 12 is 1°C-10°C, which can be adjusted as needed, with a shelf life of 5-8 days. The fresh food compartment 13 can be used to store fresh meat, fish, shellfish, dairy products, etc., keeping them fresh without freezing them, and allowing for easy access. The temperature of the fresh food compartment 13 is approximately 0°C, with a shelf life of about three days. The variable temperature compartment 14 allows for temperature adjustment according to the needs of food storage. Food storage containers 15 can be installed in the freezer compartment 11, refrigerator compartment 12, fresh food compartment 13, and variable temperature compartment 14 as needed. In other words, the food storage container 15 in this application can be a food freezing container in the freezer compartment 11, a food refrigeration container in the refrigerator compartment, or a food storage container in the variable temperature compartment 14, etc., and this application does not make any specific limitations.

[0027] Please see also Figure 2 In some embodiments, the ventilation assembly 20 is located inside the refrigerator body 10 and is disposed on one side of the air inlet 150 of the food storage container, for supplying suitable gas to the food storage container 15 according to the storage conditions of the food. See also some embodiments... Figure 3 The ventilation assembly 20 includes a substrate 21 and a preservation assembly 22. The substrate 21 has a mounting groove 210 and a ventilation channel 211 passing through the mounting groove 210. One end of the ventilation channel 211 is an air inlet 2110, allowing for air exchange with the outside environment, and the other end is an air outlet, through which gas can be delivered into the preservation container 15 via the air inlet 150. The preservation assembly 22 is disposed within the mounting groove 210.

[0028] Please see also Figure 4 The substrate 21 includes a first plate 212 and a second plate 213. The first plate 212 has a recessed groove and a ventilation groove 2121 extending through the recessed groove. The second plate 213 is disposed on the first plate 212, covering the ventilation groove 2121 to form the ventilation channel 211. The second plate 213 has a through hole communicating with the recessed groove to form the mounting groove 210. The shape of the recessed groove can match the shape of the preservation component 22. The preservation component 22 is perfectly accommodated within the recessed groove.

[0029] See also Figure 5-8The food preservation component 22 includes a connecting mechanism 221, a first annular box 222, a second annular box 223, a cover plate 224, and a base assembly 225. The first annular box 222 is arranged around the connecting mechanism 221 and has a plurality of first receiving spaces 226. The second annular box 223 is sleeved on the outside of the first annular box 222 and has a plurality of second receiving spaces 227. The cover plate 224 is disposed on one side of the second annular box 223 and the first annular box 222. The base assembly 225 is disposed on the side of the second annular box 223 and the first annular box 222 away from the cover plate 224.

[0030] The connecting mechanism 221 has an air duct 228. The connecting mechanism 221 can be a protrusion on the surface of the cover plate 224 near the second annular box 223 and the first annular box 222. The extending direction of the air duct 228 is consistent with the extending direction of the ventilation channel 211, allowing air to travel from one side of the ventilation channel 211 through the air duct 228 to the other end of the ventilation channel 211. That is, the air duct 228 is a groove, which can be used to connect the two opposing first receiving spaces 226.

[0031] Multiple first-level storage spaces 226 and multiple second-level storage spaces 227 can each be equipped with functional modules. These modules can be tailored to the different preservation requirements of various foods, providing corresponding functions. These modules can include desiccants, activated carbon, temperature control mechanisms, moisture supply mechanisms, vitamin C inducers, palladium mesh, or lysozyme. Desiccants adsorb moisture to meet the requirements of foods needing dry storage. Activated carbon removes odors and harmful substances. The temperature control mechanism adjusts the temperature of the air supplied to the preservation container according to the food's storage needs; for example, the temperature can be increased for foods requiring thawing, or decreased for foods requiring frozen storage. The moisture supply mechanism provides moisture to foods requiring higher humidity. The vitamin C inducer releases vitamin C to neutralize ethylene, producing moisture and carbon dioxide, thus providing nutrients to fruits and vegetables. Lysozyme kills hundreds of bacteria, including E. coli and Staphylococcus, preventing bacterial contamination of food. The palladium mesh catalyzes the reaction of ethylene and oxygen, neutralizing ethylene, reducing oxygen concentration, and decreasing aerobic respiration in fruits and vegetables. In some embodiments of this application, the density of different functional modules located in different first accommodating spaces 226 and second accommodating spaces 227 is the same, so as to ensure that the air volume delivered into the food storage box is the same after any combination of functional modules.

[0032] The first annular box 222 and the second annular box 223 are coaxially arranged and can rotate relative to each other. Specifically, in some embodiments, the first annular box 222 and the second annular box 223 are both integral structures. In other embodiments, the first annular box 222 includes multiple first arc-shaped boxes and multiple first functional modules disposed within the multiple arc-shaped boxes, and the multiple first arc-shaped boxes are spliced ​​together to form the first annular box 222. The second annular box 223 includes multiple second arc-shaped boxes and multiple second functional modules disposed within the multiple second arc-shaped boxes, and the multiple second arc-shaped boxes are spliced ​​together to form the second annular box 223. In some embodiments, at least one of the first arc-shaped boxes in the first annular box 222 does not contain a first functional module, in order to meet the situation where some foods only require one preservation function; similarly, at least one of the second arc-shaped boxes in the second annular box 223 does not contain a second functional module. In this case, to ensure that the airflow into the food preservation boxes is the same, a substance with the same density as the first functional module that will not affect the food can be placed in the first arc-shaped box that does not contain the first functional module. Similarly, a substance with the same density as the second functional module that will not affect the food can be placed in the second arc-shaped box that does not contain the second functional module. In some embodiments, the first functional module in the first annular box 222 and the second functional module in the second annular box 223 can also be combined to provide two or more preservation functions.

[0033] Each first arc-shaped box has one or more first receiving spaces 226, and each second arc-shaped box has one or more second receiving spaces 227. This embodiment of the application describes an example where each first arc-shaped box has one first receiving space 226 and each second arc-shaped box has one second receiving space 227. A first annular box 222 can define a first annular shape, and further define a first inner circle and a first outer circle, which are concentrically arranged. It should be noted that when multiple first arc-shaped boxes are arranged to form a first annular shape, the side closer to the center is defined as the "inner" side, and the side farther from the center is defined as the "outer" side. The multiple first arc-shaped boxes have the same shape, which is equivalent to dividing the first annular shape into N equal parts. The inner arc lengths of the multiple first arc-shaped boxes are equal, and the outer arc lengths of the multiple first arc-shaped boxes are equal. A second annular box 223 can define a second annular shape, and further define a second inner circle and a second outer circle, which are concentrically arranged. The multiple second arc-shaped boxes have the same shape, which is equivalent to dividing the second annular shape into N equal parts. The inner arc lengths of the multiple second arc-shaped boxes are equal, and the outer arc lengths of the multiple second arc-shaped boxes are equal. The first and second annular rings are concentrically arranged, and the number of multiple first arc-shaped boxes is equal to the number of multiple second arc-shaped boxes. Therefore, the outer arc length of each first arc-shaped box is equal to the inner arc length of each second arc-shaped box, ensuring that when a first arc-shaped box is aligned with a second arc-shaped box, the outer arc of the first arc-shaped box coincides with the inner arc of the second arc-shaped box. Furthermore, the width of the first arc-shaped box near the air duct 228 is the same as the width of the air duct 228 near the first arc-shaped box. The first annular box 222 can rotate around the connecting mechanism 221, allowing the air duct 228 to connect two of the first arc-shaped boxes. The second annular box 223 can also rotate around the connecting mechanism 221, so that two opposing second arc-shaped boxes are respectively connected to two opposing first arc-shaped boxes connected by the air duct 228. This allows air to pass from one side of the ventilation channel 211 through the second arc-shaped box (second accommodating space 227), the first arc-shaped box (first accommodating space 226), the air duct 228, another first arc-shaped box (another first accommodating space 226), and another second arc-shaped box (another second accommodating space 227) that meets user needs, and reach the other end of the ventilation channel 211. In this way, not only can the food preservation box 15 be adjusted in a targeted manner, but it can also provide multiple preservation functions at the same time to achieve the best food storage environment, extend the food preservation period, improve the user's high standard requirements for the preservation quality of the refrigerator 1, enhance the user experience, and meet the user's high standard requirements for the food preservation period and preservation quality of the food stored in the refrigerator 1.

[0034] In some implementations, to ensure that, according to user needs, airflow from one end of the ventilation channel 211 passes only through a selected second arc-shaped box, a selected first arc-shaped box, the air duct 228, another selected first arc-shaped box, and another selected second arc-shaped box before reaching the ventilation channel 211, a first positioning mark 2220 and a second positioning mark 2230 can be respectively provided on the first annular box 222 and the second annular box 223. The first positioning mark 2220 and the second positioning mark 2230 can accurately reflect the rotation angle of the first annular box 222 and the first annular box 222, thereby determining whether the selected first arc-shaped box and the selected second arc-shaped box are aligned by controlling the position of the first positioning mark 2220 and the second positioning mark 2230. In some embodiments, when the first positioning mark 2220 and the second positioning mark 2230 are aligned, that is, when they are located on the same diameter, it indicates that the selected first arc-shaped box and the second arc-shaped box are aligned. The shape of the first positioning mark 2220 and the second positioning mark 2230 is not limited and can be designed according to actual needs, for example, it can be a rectangular positioning hole, an elliptical positioning hole, etc.

[0035] In some embodiments, the cover plate 224 is used to close one side of the first annular box 222 and the second annular box 223. In this case, the sides of the plurality of first arc-shaped boxes and the plurality of second arc-shaped boxes near the cover plate 224 can be open, and the cover plate 224 can close the sides of the plurality of first arc-shaped boxes and the plurality of second arc-shaped boxes near the cover plate 224. Of course, it is understood that in some embodiments, the sides of the plurality of first arc-shaped boxes and the plurality of second arc-shaped boxes near the cover plate 224 can also be closed. Further, the cover plate 224 may also include a first slide rail 2241 and a second slide rail 2242 for limiting the rotation of the first annular box 222 and the second annular box 223. The first slide rail 2241 and the second slide rail 2242 are coaxially arranged and surround the connecting mechanism 221, wherein the second annular box 223 is disposed on the second slide rail 2242, and the first annular box 222 is disposed on the first slide rail 2241.

[0036] In some embodiments, the second slide 2242 and the first slide 2241 are both first annular grooves, and the second annular box 223 and the first annular box 222 are respectively embedded in the second slide 2242 and the first slide 2241, so that the first annular box 222 and the second annular box 223 will not leave the original rotation track when rotating around the connecting mechanism 221.

[0037] In other embodiments, both the second slide rail 2242 and the first slide rail 2241 are first annular protrusions, and the second slide rail 2242 and the first slide rail 2241 are respectively embedded in the second annular box 223 and the first annular box 222. Specifically, the plurality of second arc-shaped boxes and the plurality of first arc-shaped boxes have second limiting spaces and first limiting spaces that define corresponding first annular protrusions, wherein the shape of the outer ring of the first annular protrusions is adapted to the second limiting spaces of the plurality of second arc-shaped boxes, so that the plurality of second arc-shaped boxes will not deviate from their original rotation track when rotating around the connecting mechanism 221, and the shape of the inner ring of the first annular protrusions is adapted to the first limiting spaces of the plurality of first arc-shaped boxes, so that the plurality of first arc-shaped boxes will not deviate from their original rotation track when rotating around the connecting mechanism 221. In addition, in some embodiments, the connecting mechanism 221 and the cover plate 224 can be integrally formed. In this case, the air duct defined by the connecting mechanism 221 can be formed by setting the cover plate 224 on one side of the second annular box 223 and the first annular box 222.

[0038] The base assembly 225 is used to support and drive the first annular box 222 and the second annular box 223 to rotate respectively. See also some embodiments. Figure 9-10 The base assembly 225 includes a first annular base 2251, a second annular base 2252, and a rotating mechanism 2253, all coaxially arranged. The first annular base 2251 is positioned corresponding to the first annular box 222 and is used to drive the first annular box 222 to rotate. The second annular base 2252 is positioned around the first annular base 2251 and corresponding to the second annular box 223, and is used to drive the second annular box 223 to rotate. The rotating mechanism 2253 is used to drive the first annular base 2251 and the second annular base 2252 to rotate respectively, thereby causing the first annular box 222 to rotate with the first annular base 2251, and causing the second annular box 223 to rotate with the second annular base 2252.

[0039] In some embodiments, the first annular base 2251 and the second annular base 2252 both have a second annular groove, and the second annular box 223 and the first annular box 222 are respectively embedded in the second annular base 2252 and the first annular base 2251, so that the multiple second arc-shaped boxes and the multiple first arc-shaped boxes will not deviate from the original rotation track when rotating around the connecting mechanism 221.

[0040] In other embodiments, both the first annular base 2251 and the second annular base 2252 have a second annular protrusion, and the first annular base 2251 and the second annular base 2252 are respectively embedded in the first annular box 222 and the second annular box 223. Specifically, the plurality of second arc-shaped boxes and the plurality of first arc-shaped boxes have a second space and a first space that define corresponding second annular protrusions, wherein the shape of the outer ring of the second annular protrusions is adapted to the second space of the plurality of second arc-shaped boxes, so that the plurality of second arc-shaped boxes will not deviate from their original rotation track when rotating around the connecting mechanism 221, and the shape of the inner ring of the second annular protrusions is adapted to the first space of the plurality of first arc-shaped boxes, so that the plurality of first arc-shaped boxes will not deviate from their original rotation track when rotating around the connecting mechanism 221.

[0041] In some embodiments, the rotating mechanism 2253 includes a first power mechanism and a second power mechanism. The first power mechanism is connected to the first annular base 2251, enabling the first annular base 2251 to rotate. The second power mechanism is connected to the second annular base 2252, enabling the second annular base 2252 to rotate. The first annular base 2251 and the second annular base 2252 can rotate simultaneously, or the second annular base 2252 can rotate after the first annular base 2251 has rotated, or vice versa; no specific limitation is made here. The first annular base 2251 and the second annular base 2252 can rotate in the same direction or in opposite directions. For example, the first annular base 2251 and the second annular base 2252 can both rotate clockwise or both rotate counterclockwise, or the first annular base 2251 can rotate clockwise and the second annular base 2252 can rotate counterclockwise, or the first annular base 2251 can rotate counterclockwise and the second annular base 2252 can rotate clockwise. There are no specific limitations here, as long as it can be ensured that the air in the ventilation channel 211 only passes through the selected first arc-shaped box and the second arc-shaped box.

[0042] In some embodiments, the rotating mechanism 2253 includes a second gear 2255 and a first gear 2254 nested together, and a drive shaft 2256 connected to the second gear 2255 and the first gear 2254. The second gear 2255 controls the rotation of the second annular base 2252, the first gear 2254 controls the rotation of the first annular base 2251, and the drive shaft 2256 is used to connect a motor to drive the rotation of the second annular base 2252 and the first annular base 2251, respectively.

[0043] In some embodiments, the second gear 2255 and the first gear 2254 can form a variable adjustment gear. The second gear 2255 has a second gear groove 2258 inside, and the first gear 2254 has a first gear groove 2257 inside. The drive shaft 2256 has a protrusion that can be matched with the first gear groove 2257 and the second gear groove 2258 respectively. When the drive shaft 2256 rotates clockwise, the first gear 2254 can rotate clockwise under the drive of the drive shaft 2256, and drive the first annular base 2251 to rotate. The second gear groove 2258 is blocked by the corresponding protrusion on the drive shaft 2256, causing the second gear 2255 to be unable to rotate, thus causing the second annular base 2252 to remain stationary. When the drive shaft 2256 rotates counterclockwise, the second gear 2255 can rotate counterclockwise under the drive of the drive shaft 2256, and drive the second annular base 2252 to rotate. The first gear groove 2257 is blocked by the corresponding protrusion on the drive shaft 2256, causing the first gear 2254 to be unable to rotate, thus causing the first annular box 222 to remain stationary. Of course, in other embodiments, when the drive shaft 2256 rotates counterclockwise, the first gear 2254 can rotate counterclockwise under the drive of the drive shaft 2256, while the second gear 2255 remains stationary; when the drive shaft 2256 rotates clockwise, the second gear 2255 can rotate clockwise under the drive of the drive shaft 2256, while the first gear 2254 remains stationary.

[0044] In some embodiments, functional labels may be provided on the first and second arc-shaped boxes to allow for rotation of the first and second annular boxes 222 and 223 as needed, and to align the desired first and second arc-shaped boxes with the air duct 228, so that airflow passes only through the selected first and second arc-shaped boxes. The functional labels can be food type labels, such as fruits, vegetables, meats, cooked food, milk, yogurt, cheese, etc., or labels for other items, such as face masks, perfumes, etc., or labels for humidity ranges, temperature ranges, deodorization, sterilization, nutrient release, etc.

[0045] Although the above description uses the preservation component 20, which includes the first annular box 222 and the second annular box 223, as an example, it is understood that the preservation component in this application is not limited to only including two annular boxes. It can also be set as needed to include one annular box, three annular boxes, or four annular boxes, etc. The more annular boxes there are, the more functions are provided, and different preservation needs can be met.

[0046] In some embodiments, see Figure 11-13In addition to the refrigerator body 10 and the ventilation assembly 20, the refrigerator 1 may also include a control device 30 for electrical connection with the motor in the rotating mechanism 2253. The control device controls the rotation of the first annular base 2251 and the second annular base 2252 by controlling the rotation of the motor. Specifically, in some embodiments, the rotation angle of the second annular box 223 and the first annular box 222 is controlled by controlling the number of gears rotating the second gear 2255 and the first gear 2254, so that the selected first and second arc-shaped boxes match the air duct 228, ensuring that the air entering the preservation box 15 is processed by specific functional modules before and after the air duct 228.

[0047] In some embodiments, the control device 30 may include a control panel 31 and a processor 32 interconnected. The control panel 31 can receive user input commands, such as selecting the type of food, defrosting commands, freezing commands, selecting a temperature range, selecting a humidity range, and selecting desired functions, such as deodorization, sterilization, and nutrient release. In one application scenario, the control panel 31 may include a function selection button 310 disposed on the substrate 21. The function selection button 310 allows the user to select the desired function or the food to be stored. The control device 30 can automatically control the rotation of the motor based on the user's selection. In another application scenario, the control panel 31 may be a touch screen, allowing the user to issue corresponding commands through operation on the touch screen. The processor 32 can analyze the received commands and control the rotation of the first annular box 222 and the second annular box 223.

[0048] In some embodiments, the control device 30 may further include a prompting device 33 for prompting the user to input instructions, such as prompting the user to input the type of food or item to be placed; it may also be used to prompt the user to select the desired function, such as deodorization, sterilization, or nutrient release, to achieve interaction between the device and the user. The control device 30 may also prompt the user about the storage time of the food, allowing the user to process the food before it spoils.

[0049] In one embodiment of this application, the control device 30 includes a display device 34, which is used to display to the user the type of food or item selected, or the selected functional conditions, or the suggested storage conditions, or the storage time of the food, etc.

[0050] In another application scenario, the control device 30 may include a voice receiver 35, which can be used to receive voice control commands issued by the user. Specifically, it may include issuing commands in voice form to prompt the user to input the type of food or item to be placed in or to input storage conditions, such as deodorization, sterilization, and nutrient release. The processor 32 is used to control the rotation of the first annular box 222 and the second annular box 223 according to the received voice control commands.

[0051] In another application scenario, a user can send user commands to refrigerator 1 via a terminal device independent of refrigerator 1, such as a mobile phone, tablet, or laptop. This terminal device is configured to establish a wireless connection with control device 30, such as a Bluetooth connection or a Wi-Fi connection, to send user commands to control device 30. Specifically, corresponding applications or plugins can be installed on the terminal device, and the user can open the application or plugin and perform corresponding operations within it.

[0052] In one embodiment of this application, the food storage box 15 may include an identification device for identifying the type of food or item placed inside the food storage box 15 and feeding back the identification information to the control device 30. The control device 30 automatically determines the storage conditions of the food or item according to the type of food or item, and automatically controls the rotation of the first annular box 222 and the second annular box 223 so that the selected first arc-shaped box and the second arc-shaped box meet the storage requirements of the food or item.

[0053] It should be noted that the preservation component 22 in this application is not limited to only including two rings of functional boxes, namely the first ring box 222 and the second ring box 223, but may also include three or even more rings of functional boxes, which can be set according to specific actual needs.

[0054] The refrigerator provided in this application has the following advantages: First, the ventilation component provided in this application includes a rotatable first annular box and a second annular box. The first annular box includes multiple first arc-shaped boxes, and the second annular box includes multiple second arc-shaped boxes. Different arc-shaped boxes specifically store corresponding functional modules, which can provide corresponding functional modules for different food's different needs for preservation environment. Second, the first annular box and the second annular box are provided with a first positioning mark and a second positioning mark, which match the base assembly. The first annular box and the second annular box are controlled to rotate freely. By controlling the free rotation of the inner second annular box, the functional modules can be automatically matched. Therefore, different functions can be provided according to the storage needs of different foods, with precise positioning to achieve the best storage conditions or deodorization function, extend the food preservation period, and improve the preservation quality. Third, this application can also automatically control the rotation of the first annular box and the second annular box according to user needs, and perform priority matching to achieve the best storage environment for different foods, thereby improving product quality and user experience.
