[0002] In daily life, refrigerators are an indispensable household refrigeration appliance. One of their core functions is to preserve food, delay its spoilage, retain its nutrition and taste, and meet people's daily needs for fresh food.

[0003] As people's living standards improve, their requirements for food preservation have shifted from "basically not rotting" to "long-term freshness, nutrition, and flavor preservation." Furthermore, it is necessary to adapt to the diverse preservation needs of various food products (such as vegetables, fruits, meats, cooked foods, and dairy products). This places higher demands on the precision, adaptability, and efficiency of refrigerator preservation technology. Utility Model Content

[0004] This manual provides a storage structure and refrigeration equipment that can improve the preservation of food.

[0005] Firstly, this specification provides a storage structure, including: A storage room, providing storage space; A loading component is provided in the storage space; An alternating electric field generating device includes an alternating electric field generating component, an electric field releasing component, and a grounding electrode plate. The electric field releasing component and the grounding electrode plate are spaced apart. A carrying component is located between the electric field releasing component and the grounding electrode plate. The alternating electric field generating component is electrically connected to the electric field releasing component and is used to provide alternating current to the electric field releasing component. The electric field releasing component includes an electrode plate assembly and a spike structure, with the spike structure disposed on the electrode plate assembly.

[0006] In some alternative embodiments, the electrode assembly includes a main electrode plate electrically connected to the alternating electric field generating component, and the spike structure is disposed on the main electrode plate.

[0007] In some alternative embodiments, the electrode assembly includes a main electrode and a sensing electrode spaced apart, the main electrode being mounted on the storage compartment and the sensing electrode being mounted on the carrying member, wherein the projection area of ​​the main electrode and the projection area of ​​the sensing electrode at least partially overlap along the thickness direction of the main electrode, and the spike structure is provided on the main electrode and / or the sensing electrode.

[0008] In some alternative embodiments, the storage compartment has a height direction, and the main electrode plate, the sensing electrode plate, and the grounding electrode plate are arranged sequentially at intervals along the height direction.

[0009] In some alternative embodiments, the loading member includes a loading base plate, the sensing electrode plate is located on the bottom surface of the loading base plate, the spike structure extends upward from the sensing electrode plate, and at least a portion of the spike structure is located above the loading base plate.

[0010] In some alternative embodiments, the sensing plate is annular.

[0011] In some alternative embodiments, the sensing plate has a polygonal structure, and the sensing plate includes multiple sides with adjacent sides smoothly transitioning.

[0012] In some optional embodiments, the projected area of ​​the sensing electrode is S1 along the thickness direction of the main electrode plate, and the projected area of ​​the main electrode plate is S2, wherein S1 and S2 satisfy the following inequality: S1≥0.7×S2; In some optional embodiments, the distance between the grounding electrode and the main electrode is less than or equal to 300 mm; In some alternative embodiments, the distance between the main electrode plate and the inductive electrode plate is less than or equal to 100 mm.

[0013] In some optional embodiments, the electric field strength released by the main electrode plate is in the range of 3kV / m-20kV / m; In some alternative embodiments, the frequency of the electric field released by the main electrode plate is in the range of 20Hz-100Hz; In some alternative embodiments, the storage structure further includes a refrigeration device connected to the storage space, the temperature of which is in the range of -2°C to 2°C.

[0014] In some alternative embodiments, the projection area of ​​the substrate plate is located within the electrode assembly along the thickness direction of the main electrode plate.

[0015] Secondly, this specification provides a refrigeration device, including: a storage structure as described in any of the preceding claims.

[0016] The storage structure and refrigeration equipment provided in this manual have at least the following advantages: On one hand, the main electrode can discharge to form an alternating electric field. Due to the presence of the grounding electrode, the alternating electric field is confined between the main electrode and the grounding electrode, thus exerting the following effects on the food on the storage component: the alternating electric field interferes with the metabolic activities of microorganisms, such as ion transport and enzymatic reactions, inhibiting their growth and reproduction. Simultaneously, the alternating electric field force can also act on polar groups (such as amino and carboxyl groups) in enzyme molecules, altering the enzyme structure and thereby destroying the active structure of the enzyme, inhibiting enzyme activity, and even leading to enzyme inactivation. Therefore, the dual effect of the alternating electric field on microbial metabolism and enzyme activity creates a synergistic effect of "bacterial inhibition + enzyme control." This effect reduces the limitations of single preservation methods (such as relying solely on low temperature), and even when the temperature in the storage room fluctuates slightly, the stable electric field can maintain the preservation effect, improving the stability of food preservation.

[0017] On the other hand, the tip effect of the spiked structure can generate a strong electric field at a lower input power, thereby increasing the electric field strength. At the same time, the spiked structure can generate ozone ions by ionizing the air. Ozone ions have strong oxidizing properties and can destroy the cell membranes and protein structures of microorganisms (bacteria, fungi, viruses, etc.), killing or inhibiting their growth. This, combined with the electric field force, can achieve a better preservation effect. Attached Figure Description

[0020] The technical solutions in the embodiments (or "implementations") of this specification will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0021] If the embodiments of this specification contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this specification are for descriptive convenience only and should not be construed as indicating or implying relative importance.

[0022] This specification provides a storage structure and refrigeration device that can improve the preservation effect of food. The storage structure and refrigeration device are described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments and implementation methods can be combined with each other.

[0023] This specification provides a storage structure through its embodiments. (Refer to...) Figures 1 to 3 The storage structure includes: a storage chamber 10, a carrying component 20, and an alternating electric field generating device 30.

[0024] The storage room 10 has a storage space 13, and the carrying component 20 is disposed in the storage space 13. The alternating electric field generating device 30 includes an alternating electric field generating component 31, an electric field releasing component, and a grounding electrode 33. The electric field releasing component and the grounding electrode 33 are spaced apart. The carrying component 20 is located between the electric field releasing component and the grounding electrode 33. The alternating electric field generating component 31 is electrically connected to the electric field releasing component and is used to provide alternating current to the electric field releasing component. The electric field releasing component includes an electrode assembly 32 and a spike structure 322. The spike structure 322 is disposed on the electrode assembly 32.

[0025] As described above, on the one hand, the main electrode 321 can discharge to form an alternating electric field. Due to the presence of the ground electrode 33, the alternating electric field is confined between the main electrode 321 and the ground electrode 33, thus exerting the following effects on the food on the carrier component 20: The alternating electric field interferes with the metabolic activities of microorganisms, such as ion transport and enzymatic reactions, inhibiting their growth and reproduction. Simultaneously, the alternating electric field force can also act on polar groups (such as amino and carboxyl groups) in enzyme molecules, altering the enzyme structure and thereby destroying the active structure of the enzyme, inhibiting enzyme activity, and even causing enzyme inactivation. Therefore, the dual effect of the alternating electric field on microbial metabolism and enzyme activity forms a synergistic effect of "antibacterial inhibition + enzyme control." This effect reduces the limitations of a single preservation method (such as relying solely on low temperature), and even when the temperature fluctuates slightly within the storage compartment 10, the preservation effect can be maintained through a stable electric field, improving the stability of food preservation.

[0026] On the other hand, the tip effect of the spike structure 322 can generate a strong electric field at a lower input power to increase the electric field strength. At the same time, the spike structure 322 can generate ozone ions by ionizing the air. Ozone ions have strong oxidizing properties and can destroy the cell membrane and protein structure of microorganisms (bacteria, fungi, viruses, etc.), kill or inhibit their growth, and thus achieve a better preservation effect in conjunction with the electric field force.

[0027] In some embodiments, the aforementioned carrying member 20 may be a drawer, shelf, or partition, but is not limited thereto. The alternating electric field generating component 31 may include a low-voltage power supply 311 and a booster device 312. The low-voltage power supply 311 is electrically connected to the booster device 312, and the low-voltage AC power output by the low-voltage power supply 311 can be boosted to high-voltage AC power at the booster device 312. The booster device 312 is electrically connected to the main electrode plate 321, and outputs the boosted high-voltage AC power to the main electrode plate 321. Thus, the main electrode plate 321 discharges through the received high-voltage AC power, thereby forming an alternating electric field. The voltage provided by the low-voltage power supply 311 may be, but is not limited to, 220V, and the booster device 312 may be a boost circuit. For specific details, please refer to relevant technologies; this specification does not impose specific limitations on either aspect.

[0028] In some embodiments, the electrode assembly 32 includes a main electrode 321 and a sensing electrode 323 spaced apart. The main electrode 321 is mounted on the storage compartment 10, and the sensing electrode 323 is mounted on the carrying member 20. Along the thickness direction of the main electrode 321, the projection area of ​​the main electrode 321 and the projection area of ​​the sensing electrode 323 at least partially overlap. The spike structure 322 is provided on the main electrode 321 or the sensing electrode 323.

[0029] Thus, when the main electrode plate 321 discharges, the induction electrode plate 323 can generate an induced current, forming an eddy electric field, further enhancing the electric field force received by the food. Moreover, since the induction electrode plate 323 is directly mounted on the carrier component 20, the eddy electric field generated by the induction electrode plate 323 can fill the "weak areas" of the main electric field, making the electric field distribution in the carrier component 20 area more uniform. Simultaneously, compared to the main electrode plate 321, the induction electrode plate 323 is closer to the food, and the electric field force acts more directly on the surface and interior of the food. With the same output power as the main electrode plate 321, the induction electrode plate 323 can increase the effective electric field strength required for the food, more quickly inhibiting microbial metabolism and enzyme activity, and improving preservation efficiency.

[0030] It should be noted that the spike structure 322 can be directly machined onto the induction electrode plate 323 or the main electrode plate 321 using methods such as stamping, etching, or CNC milling. Alternatively, the spike structure 322 can be fixed to the induction electrode plate 323 or the main electrode plate 321 through physical connection methods (such as welding, inlaying, or riveting), but is not limited to these methods. Similarly, the shape of the spike structure 322 can be conical (such as a cone, pyramid, or irregular cone) or needle-like, but is not limited to these methods.

[0031] In some embodiments, the electrode assembly 32 may include only the main electrode 321, excluding the sensing electrode 323. In this case, the spike structure 322 may be disposed on the main electrode 321.

[0032] In some embodiments, the storage compartment 10 has a height direction, and the main electrode plate 321, the sensing electrode plate 323 and the grounding electrode plate 33 are arranged sequentially at intervals along this height direction.

[0033] In this way, the main electrode plate 321 and the sensing electrode plate 323, which are spaced apart along the height direction, do not occupy additional horizontal storage area, thus preserving the original load-bearing space of the storage component 20 (such as a shelf or drawer), ensuring that the amount of food stored is not affected, and improving the overall storage efficiency. Furthermore, it is easy to understand that food is generally not stacked along the height direction, so the food will not block each other, allowing the electric field to cover all the food on the storage component 20.

[0034] Of course, in other embodiments, the main electrode plate 321 and the sensing electrode plate 323 may also be spaced apart along the width or length of the storage space 13, but are not limited thereto.

[0035] In some embodiments, the carrying member 20 includes a carrying base plate 21 for supporting the weight of the food ingredients, and an induction electrode plate 323 is mounted on the carrying base plate 21.

[0036] The base plate 21 is the component that directly supports the food. The induction plate 323 is installed on it and can make close contact with the bottom of the food. This layout allows the electric field to act directly on the bottom area with the largest contact area of ​​the food, making the effect more direct.

[0037] The induction plate 323 can be located on the bottom surface of the loading base plate 21 or on the top surface of the loading base plate 21.

[0038] When the sensing plate 323 is located on the bottom surface of the base plate 21, the upper surface of the base plate 21 remains flat. Food can directly contact the base plate 21 without having to avoid the plate, making placement smoother and preventing food from sliding or becoming unstable due to the plate protruding. At the same time, bottom mounting prevents the sensing plate 323 from directly contacting food, water stains, or food residue, reducing wear on the surface of the sensing plate 323 caused by food friction, and preventing liquid from seeping into the connection of the sensing plate 323, which could cause short circuits or damage.

[0039] Furthermore, the sensing electrode 323 is located on the bottom surface of the loading base plate 21, and the spike structure 322 extends upward from the sensing electrode 323, with at least a portion of the spike structure 322 located above the loading base plate 21.

[0040] At least a portion of the spiked structure 322 is located above the substrate 21, which can shorten the distance between the spiked structure 322 and the food, allowing the electric field released by the spiked structure 322 and the ionized air to act on the food at close range, thereby enhancing the preservation efficiency.

[0041] Furthermore, the storage chamber 10 includes a storage top plate 11 and a storage bottom plate 12, and the main electrode plate 321 is installed on the storage bottom plate 12; wherein, the distance between the sensing electrode plate 323 and the main electrode plate 321 is smaller than the distance between the sensing electrode plate 323 and the storage top plate 11.

[0042] In other words, compared to mounting the main electrode plate 321 on the storage top plate 11, this embodiment mounts the main electrode plate 321 on the storage bottom plate 12, resulting in a smaller distance between the main electrode plate 321 and the sensing electrode plate 323. Based on the correlation between electric field strength and electrode spacing, a stronger electric field can be generated at closer distances under the same input power. This can more quickly interfere with microbial metabolism, disrupt enzyme activity, and improve the preservation efficiency of food on the storage component 20.

[0043] Specifically, the main electrode plate 321 can be located on the side of the storage base plate 12 close to the sensing electrode plate 323 to further reduce the distance between the main electrode plate 321 and the sensing electrode plate 323, but is not limited to this.

[0044] In some embodiments, the projection area of ​​the food carrier 20 is located within the main electrode plate 321 along its thickness direction. Specifically, the projection area of ​​the food carrier base plate 21 of the food carrier 20 falls within the main electrode plate 321. The food carrier 20 is the direct support area for the food, and its projection completely falls within the main electrode plate 321, meaning that the electric field range of the main electrode plate 321 can completely cover the entire food carrier 20. Whether the food is placed in the center or at the edge of the food carrier 20, it can be affected by the electric field, preventing insufficient electric field coverage at the edges from compromising the preservation effect.

[0045] In some embodiments, along the thickness direction of the main electrode plate 321, the projected area of ​​the sensing electrode plate 323 is S1, and the projected area of ​​the main electrode plate 321 is S2. S1 and S2 satisfy the following inequality: S1≥0.7×S2.

[0046] The projected areas of the induction plate 323 and the main plate 321 satisfy S1≥0.7×S2, meaning that they are at least 70% (e.g., 70%, 80%, 90%, 100%, 110%). This overlapping region is the core region of electric field coupling. A sufficiently large overlapping area allows the electric field generated by the main plate 321 to act more fully on the induction plate 323, enabling it to efficiently generate induced current and eddy electric field, thereby improving the preservation effect.

[0047] In some embodiments, the induction plate 323 is annular. Here, annular refers to a circle, ellipse, or an arc shape with its ends connected. The annular structure has no obvious corners, and the electric field diffuses uniformly along the annular contour, forming a relatively uniform electric field region radiating inwards and outwards from the ring as the center. Compared to square or other angular plates, this avoids the problem of excessively concentrated electric field at the corners and weak electric field at the center or edges.

[0048] Of course, in other embodiments, the sensing electrode 323 has a polygonal structure, and the sensing electrode 323 includes multiple sides, with adjacent sides smoothly transitioning.

[0049] The polygonal structure (such as rectangles, hexagons, etc.) closely matches the shape of the square or rectangular storage base 21 (such as shelves or drawers) commonly found in refrigerators. This maximizes the use of the planar space of the storage base 21, reduces the gap between the electrode and the storage area, and increases the coverage of the electric field over the storage area. At the same time, the smooth transition design of adjacent sides eliminates the electric field tip effect at the corners of traditional right-angled polygonal electrode plates, and minimizes the problem of excessive electric field concentration at the corners and weak electric field in other areas.

[0050] Furthermore, the dimension of the loading base plate 21 along the first direction is equal to the dimension of the sensing electrode plate 323 along the first direction, and the first direction is the same as the dimension of the loading base plate 21. The thickness direction is perpendicular. The first direction here can be the length direction of the loading base plate 21, the width direction of the loading base plate 21, or both the length direction and the width direction of the loading base plate 21.

[0051] The induction plate 323 and the base plate 21 are equal in length, width or both, which means that the induction plate 323 can fit the horizontal contour of the base plate 21, so that the electric field covers every area of ​​the base plate 21 as much as possible. No matter whether the food is placed on the edge, corner or center, it can be affected by the electric field, thus minimizing the elimination of electric field blind spots.

[0052] In some embodiments, the distance between the grounding plate 33 and the main plate 321 is less than or equal to 300 mm.

[0053] The grounding plate 33 and the main plate 321 face each other, forming a symmetrical electric field structure of "main plate 321 - grounding plate 33". This structure can fix the distribution range of the electric field, prevent the electric field from spreading disorderly to other areas of the storage compartment 10, and allow the electric field to act more concentratedly on the loading component 20 (food area) between them. At the same time, the distance between the grounding plate 33 and the main plate 321 is ≤300mm, which is a close-range plate layout. According to the characteristics of the electric field, the close distance can generate a sufficiently strong electric field at a lower input power, so that the electric field strength required for preservation can be met without increasing the power of the main plate 321, directly reducing the energy consumption of the equipment. It should be noted that the minimum distance between the main plate 321 and the grounding plate 33 can be defined by the actual storage space, so this specification does not require a minimum distance.

[0054] In some embodiments, the distance between the main electrode plate 321 and the induction electrode plate 323 is less than or equal to 100 mm. A distance of ≤100 mm is considered a close-range arrangement, which allows for more efficient electric field coupling between the main electrode plate 321 and the induction electrode plate 323. The alternating electric field generated by the main electrode plate 321 can act on the induction electrode plate 323 quickly and efficiently, causing it to generate a stronger induced current and eddy current electric field.

[0055] For example, the spacing between the main electrode plate 321 and the sensing electrode plate 323 can be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, or 100mm, but is not limited to these.

[0056] In some embodiments, the storage structure further includes a cooling device connected to the storage space 13, used to control the temperature of the storage space 13 within the range of -2°C to 2°C. Exemplarily, the temperature of the storage space 13 can be -2°C, -1°C, 0°C, 1°C, or 2°C, but is not limited thereto.

[0057] -2℃ to 2℃ is the ideal temperature range for preserving most foods (especially fresh produce, fruits and vegetables, and cooked foods). This temperature significantly reduces the rate of microbial growth, slows down respiration and enzymatic reactions, and provides a fundamental guarantee for food preservation. An alternating electric field can further inhibit the metabolism of microorganisms that survive at low temperatures, while also destroying some enzymes that remain active at low temperatures. The combination of these two methods creates a synergistic effect, extending the shelf life of food several times compared to low-temperature preservation alone, better meeting the demand for "long-term freshness."

[0058] In some embodiments, the electric field frequency released by the main electrode 321 is in the range of 20Hz to 100Hz. Exemplarily, the electric field frequency can be 20Hz, 30Hz, 40Hz, 50Hz, 60Hz, 70Hz, 80Hz, 90Hz or 100Hz, but is not limited thereto.

[0059] It's easy to understand that the metabolic activities of microorganisms (such as bacteria and fungi), such as the opening and closing of ion channels in their cell membranes and the transmembrane transport of nutrients, exhibit natural low-frequency rhythms (mostly in the tens of hertz range). An alternating electric field of 20Hz-100Hz can disrupt this rhythm through "frequency resonance," disrupting the ion concentration balance and inhibiting growth and reproduction. Simultaneously, the 20Hz-100Hz electric field can cause the polar groups (amino and carboxyl groups) of enzymes to vibrate directionally through periodic electromagnetic forces, leading to the loosening or even disintegration of the active site structure. Therefore, controlling the electric field frequency released by the main electrode 321 within the 20Hz-100Hz range can match the target points of microbial metabolism and enzyme activity, improving the preservation effect.

[0060] In some embodiments, the electric field strength released by the main electrode 321 is in the range of 3 kV / m to 20 kV / m. Exemplarily, the electric field strength can be 3 kV / m, 4 kV / m, 5 kV / m, 6 kV / m, 7 kV / m, 8 kV / m, 9 kV / m, 10 kV / m, 11 kV / m, 12 kV / m, 13 kV / m, 14 kV / m, 15 kV / m, 16 kV / m, 17 kV / m, 18 kV / m, 19 kV / m, or 20 kV / m, but is not limited thereto.

[0061] It's easy to understand that electric field strengths of 3kV / m to 20kV / m are sufficient to interfere with ion transport in microbial cell membranes, causing electroporation, and simultaneously damaging the active structure of enzymes. Among these, lower electric field strengths, such as 3kV / m, can meet the basic preservation needs of fruits and vegetables (inhibiting respiration and providing mild antibacterial effects); while strengths of 9kV / m to 20kV / m are more effective against perishable foods such as meat and cooked dishes, enhancing the inhibitory effect on microorganisms and highly active enzymes.

[0062] In some embodiments, the material of the induction plate 323 may be copper, silver, aluminum or a high permeability conductor, including but not limited to iron, cobalt and nickel.

[0063] It's easy to understand that higher electrical conductivity (such as in good conductors like silver, copper, and aluminum) results in a greater number of free electrons. Under the same vortex electric field strength, this leads to stronger charge migration and a larger induced current. Conversely, insulators (such as plastics and ceramics) produce almost no induced current because they have virtually no free charges; semiconductors (such as silicon) have lower electrical conductivity and therefore weaker induced currents. Materials with high magnetic permeability enhance the magnetic field changes generated by alternating electric fields, thereby strengthening the vortex electric field (induced electric field) through Faraday's law of electromagnetic induction. Furthermore, ferromagnetic materials are often conductors themselves, and the superimposed, stronger induced electric field significantly increases the induced current.

[0064] Based on the same inventive concept, this application also provides a refrigeration device including any of the above embodiments or implementation methods, the storage structure described above, and the cabinet 40.

[0065] like Figure 1 In the embodiment shown, the storage compartment 10 of the storage structure is located inside the cabinet 40, and the alternating electric field generating component 31 is installed on the outer wall of the cabinet 40, but is not limited thereto.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
