[0002] In the field of food preservation, traditional preservation methods mainly rely on technologies such as temperature control, humidity regulation and modified atmosphere packaging.

[0003] Traditional preservation methods often use fixed preservation parameters, such as constant temperature, humidity or gas concentration, to deal with different types and states of food. However, in reality, different food ingredients have different requirements for preservation conditions, and even the same food ingredients require different preservation environments at different stages. This single preservation method cannot accurately meet the preservation needs of various food ingredients, resulting in poor preservation effects. Summary of the invention

[0023] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0024] It should be noted that the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0025] like Figure 1 As shown, a method for controlling food preservation is provided in one embodiment of the present invention.

[0026] The food preservation control method is applied to a storage device.

[0027] In one embodiment, the storage device may be configured as described below, and the corresponding technical solution is referenced in the control method provided in the present invention.

[0028] like Figure 1 As shown, one embodiment of the present invention provides a food preservation control method, comprising the following steps.

[0029] Step S1, determining N volume ratios corresponding to N kinds of food materials in a storage device, where the volume ratios represent space occupied by the food materials in the storage device;

[0030] Step S2, determining a target magnetic field strength of the storage device based on the target food material corresponding to the maximum volume ratio;

[0031] Step S3, controlling the magnetic control assembly in the storage device so that the actual magnetic field strength generated by the magnetic control assembly matches the target magnetic field strength, N>0, where N is an integer.

[0032] In this way, by obtaining the space occupancy of N kinds of food ingredients in the storage device, and taking the food ingredient that occupies the largest space as the target food ingredient, and taking its corresponding target magnetic field strength as the target, the working mode of the magnetic control component is dynamically adjusted to ensure that the magnetic control component preferentially provides a suitable magnetic field environment to the food ingredient that most needs preservation conditions, thereby ensuring that all food ingredients in the storage device can receive efficient and personalized preservation treatment, which not only improves the overall preservation effect, but also optimizes energy consumption management.

[0033] In step S1, the volume ratio refers to the ratio between the space occupied by the food itself and the total space that the storage device can accommodate. The volume ratio is a quantitative indicator used to characterize the space occupied by the food in the storage device. It can be seen that the larger the volume ratio, the larger the space occupied by the food of this type in the storage device; conversely, the smaller the volume ratio, the smaller the space occupied by the food of this type in the storage device.

[0034] Therefore, in step S2, determining the target magnetic field strength of the storage device based on the target food corresponding to the maximum volume can ensure to a certain extent that most of the food (at least the food that dominates in terms of volume) can obtain a good preservation effect.

[0035] In one embodiment, the N volume ratios are arranged in descending order, and the magnetic control components are controlled according to the sorting results to perform magnetic field control in accordance with the corresponding target magnetic field strengths.

[0036] In this way, by controlling the magnetic field in sequence according to the sorting results, it can be ensured that each ingredient is stored in its optimal magnetic field environment, thereby maximizing the shelf life and maintaining the nutritional value and taste of the ingredient.

[0037] In this embodiment, according to the requirements or priorities of the food materials for magnetic field strength, it is ensured that the N kinds of food materials in the storage device can be preserved according to their specific and optimal target magnetic field strength. The goal is not to maximize the efficiency per unit time, but to optimize the overall preservation effect.

[0038] In step S2, the target magnetic field strength refers to the magnetic field strength that the storage device hopes to achieve, which can be understood as the optimal magnetic field for achieving the best preservation effect of food. The target magnetic field strength is related to at least one of the type, quantity or state of the food in the storage device.

[0039] On the one hand, the target magnetic field strength can be an independent value. This means that for a certain food or under a certain storage condition, there is an optimal magnetic field strength value. On the other hand, the target magnetic field strength can also be an interval range. In this case, the preservation of food may not require a precise magnetic field strength value, but the most ideal preservation effect can be achieved within a specific range. The present invention does not make specific restrictions on this.

[0040] In a specific embodiment, based on a preset mapping relationship, a plurality of target magnetic field strengths corresponding to a plurality of food types in the storage device are determined. In other words, each type of food has a corresponding target magnetic field strength, and the target magnetic field strengths corresponding to different types of food may be equal or unequal.

[0041] In a specific embodiment, when the target food includes multiple types of food, the target magnetic field strength is determined according to the average value of the target magnetic field strength corresponding to each target food. In this way, a relatively compromised magnetic field strength value is obtained by calculating the average value, which can meet the preservation requirements of multiple food to a certain extent and reduce food loss caused by improper magnetic field strength setting.

[0042] In another specific embodiment, when the target magnetic field strength is an interval range, the local minimum target magnetic field strength and the local maximum magnetic field strength corresponding to each target food are obtained; the average value of the corresponding local minimum magnetic field strength and the average value of the corresponding local maximum magnetic field strength are calculated respectively to obtain the minimum target magnetic field strength and the maximum target magnetic field strength corresponding to the storage device.

[0043] In step S1, the storage device refers to a device or container specifically used for storing, preserving and managing food. These devices can ensure that the food remains fresh, nutritious and tasty during storage. The storage device can be a refrigerator, a freezer, or a module in a refrigerator or a freezer, such as a fresh-keeping drawer.

[0044] It should be noted that the effect of magnetic field on food preservation is mainly reflected in the fact that magnetic field can inhibit the growth of microorganisms and molds, thereby extending the storage period of food. Specifically, when using magnetic field to assist in the storage of food, the magnetic field limits the free path of water molecules to a certain extent, which is specifically manifested in the breaking of hydrogen bonds in the water molecule family, so that the growth of water crystal nuclei is inhibited during the phase change process, the growth rate of ice crystals is higher than the migration rate of water molecules, and the ice crystals produced are smaller, so the loss to cells is small, the loss rate of juice in food is reduced, and the nutrition and taste of food can be better preserved. Therefore, magnetic field can be used to assist in the storage of food, thereby achieving the purpose of extending the storage period of food.

[0045] like Figure 2 As shown, in one embodiment, the step S1 of determining N volume ratios corresponding to N kinds of food materials in the storage device may specifically include the following steps.

[0046] Step S11, obtaining the total volume of the storage device and the individual volume occupied by each food ingredient;

[0047] Step S12, respectively calculating the ratio of the individual volume to the total volume of each food ingredient to determine the corresponding volume ratio.

[0048] In this way, the corresponding volume ratio is determined by calculating the ratio of the individual volume of the food to the total volume. This method is simple to calculate and easy to understand.

[0049] In step S11, the individual volume refers to the size of the space occupied by the food alone, and is used to measure the actual size of the space occupied by the food in the storage device. The total volume refers to the total volume or total space size that the storage device can accommodate the food.

[0050] For example, assuming that the total volume of the storage device is V, and the individual volumes corresponding to the N kinds of food in the storage device are V1, V2, ..., Vn, respectively, then the corresponding volume ratios are △V1 = V1 / V, △V2 = V2 / V, ..., △Vn = Vn / V. It can be seen that when the volume ratio of a certain food is larger, it indicates that the capacity of the food is larger, and vice versa, when the volume ratio of a certain food is smaller, it indicates that the capacity of the food is smaller.

[0051] In other embodiments, the total volume occupied by N kinds of food materials in the storage device and the individual volume occupied by each food material are obtained; the ratio of the individual volume of each food material to the total volume is calculated respectively to determine the corresponding volume ratio.

[0052] In this embodiment, the calculation method gives the relative size of a certain ingredient among all ingredients, which is used to determine the spatial competition relationship between different ingredients in the storage device, that is, which ingredient occupies a dominant position.

[0053] In step S3, the magnetron component is a device or apparatus component capable of generating and controlling a magnetic field.

[0054] In one embodiment, a magnetic field strength sensor is used to detect the actual current magnetic field strength of the storage device.

[0055] Based on this, in one embodiment, step S3 may specifically include the following steps.

[0056] Step S311, obtaining a minimum target magnetic field strength and a maximum target magnetic field strength corresponding to the target food;

[0057] Step S312, detecting and determining whether the actual magnetic field strength in the storage device is less than the minimum target magnetic field strength;

[0058] If yes, the process jumps to step S313 to increase the current provided by the power supply to the magnetron assembly so that the actual magnetic field strength falls within the range of the minimum target magnetic field strength and the maximum target magnetic field strength.

[0059] In another embodiment, step S3 may specifically include the following steps.

[0060] Step S321, obtaining a minimum target magnetic field strength and a maximum target magnetic field strength corresponding to the target food;

[0061] Step S322, detecting and determining whether the actual magnetic field strength in the storage device is greater than the maximum target magnetic field strength;

[0062] If yes, the process jumps to step S323 to reduce the current provided by the power supply to the magnetron assembly so that the actual magnetic field strength falls within the range of the minimum target magnetic field strength and the maximum target magnetic field strength.

[0063] In this way, by adjusting the current flowing to the magnetron component, the magnetic field strength in the storage device is affected, thereby achieving precise control of the actual magnetic field strength in the storage device, and the control method is flexible and easy to implement.

[0064] In a specific embodiment, the magnetron assembly includes a first electromagnetic coil for generating a first magnetic field. The magnetron assembly also includes a second electromagnetic coil, which is arranged within the range of the first magnetic field and is arranged to generate a second magnetic field; the storage device is arranged between the first electromagnetic coil and the second electromagnetic coil, and the actual magnetic field strength in the storage device is determined by the first magnetic field and the second magnetic field.

[0065] Based on this, in a specific embodiment, Figure 3 As shown, step S3 may specifically include the following steps.

[0066] Step S331, controlling the power supply to provide current to the first electromagnetic coil, detecting and determining whether the magnetic field strength corresponding to the first magnetic field meets the target magnetic field strength;

[0067] If not, jump to step S332, control the power supply to provide current to the second electromagnetic coil to generate a second magnetic field, so that the actual magnetic field strength in the storage device matches the target magnetic field strength; wherein the actual magnetic field strength is determined based on the first magnetic field and the second magnetic field.

[0068] In this way, by detecting and judging whether the magnetic field strength of the first magnetic field generated by the first electromagnetic coil after being energized meets the target magnetic field strength, when it does not meet the target, the second electromagnetic coil is energized to generate the second magnetic field, so that the actual magnetic field strengths corresponding to the first magnetic field and the second magnetic field match the target magnetic field strength. This sequential arrangement is intended to first try to achieve the goal using a single electromagnetic coil, and then introduce a second electromagnetic coil when the single effect is insufficient, so as to flexibly adjust and enhance the overall magnetic field effect.

[0069] In other embodiments, the power supply can be controlled to provide current to the second electromagnetic coil to detect and determine whether the magnetic field strength corresponding to the second magnetic field meets the target magnetic field strength; if not, the power supply can be controlled to provide current to the first electromagnetic coil to generate a first magnetic field, so that the actual magnetic field strength in the storage device matches the target magnetic field strength.

[0070] In other words, the order of energizing the first electromagnetic coil and the second electromagnetic coil in step S331 to step S332 is not specifically limited, and the control order can be adjusted according to actual conditions.

[0071] In addition, when the actual magnetic field strength is less than the minimum target magnetic field strength, it indicates that the current actual magnetic field strength is weak, and the magnetic field strength can be enhanced by superposition of different magnetic fields; when the actual magnetic field strength is greater than the maximum target magnetic field strength, it indicates that the current actual magnetic field strength is strong, and the magnetic field strength can be weakened by offsetting different magnetic fields. Therefore, the actual magnetic field strength is equal to the vector sum of the first magnetic field strength corresponding to the first magnetic field and the second magnetic field strength corresponding to the second magnetic field.

[0072] Based on this, in another embodiment, when the actual magnetic field strength in the storage device does not match the target magnetic field strength, the current direction of the power supply to the first electromagnetic coil is adjusted; and / or the current direction of the power supply to the second electromagnetic coil is adjusted.

[0073] In a specific embodiment, as shown in FIG. 4( a ), step S3 may specifically include the following steps.

[0074] Step S341, obtaining a minimum target magnetic field strength and a maximum target magnetic field strength corresponding to the target food;

[0075] Step S342, detecting and determining whether the actual magnetic field strength in the storage device is less than the minimum target magnetic field strength;

[0076] If yes, jump to step S343 and control the power supply module to provide the second electromagnetic coil with a current in the same direction as the first electromagnetic coil, so that the actual magnetic field strength falls within the range of the minimum target magnetic field strength and the maximum target magnetic field strength.

[0077] In step S342, the actual magnetic field strength in the storage device can be understood as the magnetic field strength corresponding to the first magnetic field or the second magnetic field. When the magnetic field strength generated by a single electromagnetic coil is less than the minimum target magnetic field strength, a second electromagnetic coil is introduced.

[0078] In this embodiment, according to the operation corresponding to step S343, the current directions passing through the first electromagnetic coil and the second electromagnetic coil are the same, and the corresponding magnetic field directions of the first magnetic field and the second magnetic field are the same, so that the first magnetic field and the second magnetic field are superimposed on each other, and the corresponding magnetic field strength is enhanced, so that it gradually approaches the minimum target magnetic field strength.

[0079] It should be noted that step S343 can be understood as: controlling the power supply module to provide a preset first initial current value and a second initial current value to the first electromagnetic coil and the second electromagnetic coil, respectively, and providing a current in the same direction as the first electromagnetic coil to the second electromagnetic coil. On the one hand, when the actual magnetic field strength generated by the superposition of the first magnetic field and the second magnetic field is greater than the minimum target magnetic field strength, there is no need to adjust the current in the first electromagnetic coil and / or the second electromagnetic coil.

[0080] On the other hand, when the actual magnetic field strength generated by the superposition of the first magnetic field and the second magnetic field is less than the minimum target magnetic field strength, it indicates that the actual magnetic field strength after the superposition of the first magnetic field and the second magnetic field in the same magnetic field direction has not yet reached the minimum target magnetic field strength. At this time, the current provided by the power supply to the first electromagnetic coil is increased, and / or the current provided by the power supply to the second electromagnetic coil is increased until the actual magnetic field strength falls within the range of the minimum target magnetic field strength and the maximum target magnetic field strength.

[0081] In another specific embodiment, as shown in FIG. 4( b ), step S3 may specifically include the following steps.

[0082] Step S351, obtaining a minimum target magnetic field strength and a maximum target magnetic field strength corresponding to the target food;

[0083] Step S352, detecting and determining whether the actual magnetic field strength in the storage device is greater than the maximum target magnetic field strength;

[0084] If yes, jump to step S353 and control the power supply module to provide a current in the opposite direction to the first electromagnetic coil to the second electromagnetic coil, so that the actual magnetic field strength falls within the range of the minimum target magnetic field strength and the maximum target magnetic field strength.

[0085] In this way, by adjusting the magnitude and / or direction of the current passing to the first electromagnetic coil and the second electromagnetic coil, the adjustment method is flexible and has strong robustness.

[0086] In step S352, the actual magnetic field strength in the storage device can be understood as the magnetic field strength corresponding to the first magnetic field or the second magnetic field. When the magnetic field strength generated by a single electromagnetic coil is greater than the target magnetic field strength, a second electromagnetic coil is introduced.

[0087] In this embodiment, according to the operation corresponding to step S353, the directions of the currents passing through the first electromagnetic coil and the second electromagnetic coil are opposite, and the corresponding magnetic field directions of the first magnetic field and the second magnetic field are opposite, so that the first magnetic field and the second magnetic field cancel each other out, and the corresponding magnetic field strength is weakened.

[0088] It should be noted that step S353 can be understood as: controlling the power supply module to provide a preset first initial current value and a second initial current value to the first electromagnetic coil and the second electromagnetic coil, respectively, and providing a current in the opposite direction to the first electromagnetic coil to the second electromagnetic coil. On the one hand, when the actual magnetic field strength generated after the first magnetic field and the second magnetic field are offset falls within the range of the minimum target magnetic field strength and the maximum target magnetic field strength, there is no need to adjust the current in the first electromagnetic coil and / or the second electromagnetic coil.

[0089] On the other hand, when the actual magnetic field strength generated after the first magnetic field and the second magnetic field are offset, is greater than the maximum target magnetic field strength, indicating that the actual magnetic field strength after the first magnetic field and the second magnetic field in opposite magnetic field directions are offset still exceeds the maximum target magnetic field strength. At this time, the current provided by the power supply to the first electromagnetic coil is reduced, and / or the current provided by the power supply to the second electromagnetic coil is reduced until the actual magnetic field strength falls within the range of the minimum target magnetic field strength and the maximum target magnetic field strength.

[0090] In other embodiments, the magnetron assembly may further include a first permanent magnet for generating a first magnetic field, which is a constant magnetic field. The magnetron assembly may further include a circuit module, which itself forms a closed loop, which is arranged within the range of the first magnetic field, for inducing the first magnetic field and generating an induced current to generate a second magnetic field.

[0091] In this embodiment, the direction of the output current of the circuit module is adjusted so that the actual magnetic field strength of the third magnetic field in the storage device matches the target magnetic field strength; wherein the third magnetic field is determined based on the first magnetic field and the second magnetic field.

[0092] An embodiment of the present invention provides a storage device for controlling the freshness of food in the storage device.

[0093] The storage device includes a first electromagnetic coil for generating a first magnetic field. On the one hand, the first magnetic field is used to keep the food in the storage device fresh. On the other hand, the first magnetic field indirectly affects the actual magnetic field strength in the storage device by affecting the second component.

[0094] The storage device includes a second component, which is arranged within the range of the first magnetic field generated by the first electromagnetic coil. The second component includes a second electromagnetic coil and a storage unit, wherein the second electromagnetic coil is arranged at the storage unit, and the storage unit is used to place food.

[0095] In one embodiment, when the second electromagnetic coil is energized, the second electromagnetic coil will generate a second magnetic field, and the superposition of the first magnetic field and the second magnetic field will form a combined magnetic field in the storage device, and the magnetic field strength of the combined magnetic field is related to the magnetic field strength and magnetic field direction of the first magnetic field and the second magnetic field.

[0096] Specifically, when the magnetic field strength of the combined magnetic field does not match the target magnetic field strength, the magnetic field strength and / or direction of the first magnetic field is adjusted by controlling the direction and / or current strength of the current passing through the first electromagnetic coil. And / or, the magnetic field strength and / or direction of the second magnetic field is adjusted by adjusting the direction and / or current strength of the current passing through the second electromagnetic coil, until the actual magnetic field strength of the combined magnetic field matches the target magnetic field strength.

[0097] The storage device also includes a control module, which is used to implement a food preservation control method.

[0098] In a specific embodiment, the food preservation control method can adopt the control method described above.

[0099] like Figure 5 As shown, an embodiment of the present invention provides a refrigeration device 200.

[0100] The refrigeration device 200 may specifically be a computer device, and the computer device may be a terminal device or a server.

[0101] The refrigeration device 200 includes at least one processor. The air supply control method provided by the present invention can be applied to the processor or implemented by the processor. The processor can be a central processing unit (CPU) 21.

[0102] The refrigeration device 200 includes a memory. The memory is used to store various types of data to support the operation of the refrigeration device 200. Examples of such data include: any computer program for operating on a computer device. The memory may be a read-only memory (ROM) 22, a random access memory (RAM) 23, or another storage part 28. The storage part 28 may be located inside the refrigeration device 200 or outside the refrigeration device 200.

[0103] In one embodiment, when the processor executes the computer program stored in the memory, the steps of the air supply control method in any technical solution of the present invention are performed.

[0104] In one embodiment, the refrigeration device 200 includes a central processor 21, which can perform various appropriate actions and processes according to the program stored in the read-only memory 22 or the program loaded from the storage part 28 to the random access memory 23. Various programs and data required for system operation are also stored in the random access memory 23. The central processor 21, the read-only memory 22 and the random access memory 23 are connected to each other through a bus 24. An input / output interface (Input / Output interface, i.e., I / O interface) 25 is also connected to the bus 24.

[0105] The following components are connected to the input / output interface 25: an input section 26 including a keyboard, a mouse, etc.; an output section 27 including a cathode ray tube (CRT), a liquid crystal display (LCD), etc., and a speaker, etc.; a storage section 28 including a hard disk, etc.; and a communication section 29 including a network interface card such as a LAN card, a modem, etc. The communication section 29 performs communication processing via a network such as the Internet. A drive 210 is also connected to the input / output interface 25 as needed.

[0107] In one embodiment, a computer readable storage medium stores a computer program executed by the processor mentioned above, or a food preservation control method in any of the technical solutions mentioned above.

[0108] When the processor executes the computer program, it can execute the description of the food preservation control method in any of the above technical solutions, so it will not be repeated here. In addition, the description of the beneficial effects of the same method will not be repeated.

[0109] The computer-readable storage medium may include: a flash drive, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, etc.

[0110] In summary, the present invention provides a food preservation control method and refrigeration equipment. By obtaining the space occupancy of N kinds of food in a storage device, and taking the food with the largest space as the target food, and taking its corresponding target magnetic field strength as the target, the working mode of the magnetic control component is dynamically adjusted to ensure that the magnetic control component preferentially provides a suitable magnetic field environment to the food that most needs to be preserved, thereby ensuring that all food in the storage device can be efficiently and personalizedly preserved, which not only improves the overall preservation effect, but also optimizes energy consumption management.
