Abstract
Description
Technical Field
[0001] The present invention relates to the field of household appliances, and particularly to a method and device for controlling food preservation. Background Art
[0002] In the existing field of food storage, the preservation methods of food mostly rely on the regulation of environmental conditions such as temperature and humidity. However, with the in-depth study of the preservation mechanism of food, people have gradually realized that magnetic field, as a non-contact physical means, has unique advantages in regulating the internal biochemical reactions of food and slowing down the aging process.
[0003] However, the magnetic field control methods in the existing technology often adopt a one-size-fits-all strategy, that is, the same magnetic field intensity setting is applied to all types of food. This single control method ignores the different requirements of different foods for magnetic field sensitivity due to differences in composition and structure. Specifically, the response characteristics of various foods to magnetic fields are different. Some may require a weaker magnetic field to subtly regulate their physiological metabolism, while others may require a stronger magnetic field to effectively inhibit microbial growth or enzymatic reactions.
[0004] Therefore, adopting a unified magnetic field control method not only fails to achieve the adaptive storage of food, but may also damage the quality of some foods due to inappropriate magnetic field intensity, such as nutrient loss, texture change or accelerated spoilage, ultimately affecting the overall freshness and shelf life of food.

[0026] The present invention will be described in detail below in conjunction with the specific implementation manners shown in the accompanying drawings. However, these implementation manners do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these implementation manners is included in the protection scope of the present invention.
[0027] It should be noted that the term "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article, or device. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0028] As Figure 1 shown, in an embodiment of the present invention, a food preservation control method is provided.
[0029] The food preservation control method is applied to a food preservation device and is used to preserve the food in the food preservation device.
[0030] In one embodiment, the food preservation device can be set as described above, and the corresponding technical solutions are incorporated into the control method provided by the present invention.
[0031] As Figure 1As shown in the figure, an embodiment of the present invention provides a method for controlling food ingredient preservation, including the following steps.
[0032] Step S1: Obtain several attribute characteristics of the food ingredients in the food ingredient preservation device, and determine the priority of the corresponding food ingredients according to the differences between the attribute characteristics and the corresponding standard attribute characteristics.
[0033] Step S2: Determine the target food ingredients according to the priority, and determine the magnetic field intensity corresponding to the target food ingredients as the target magnetic field intensity.
[0034] Step S3: Control the magnetic control component in the food ingredient preservation device to make the actual magnetic field intensity generated by it match the target magnetic field intensity.
[0035] In this way, by obtaining the priorities of various food ingredients in the food ingredient preservation device, and then dynamically determining and adjusting to the magnetic field intensity required for the currently highest-priority target food ingredients according to these priorities, intelligent and differential control of the magnetic field intensity is achieved. Whenever the target food ingredients with the highest priority are consumed, the system will dynamically update the target magnetic field intensity to meet the needs of the next-priority food ingredients. This dynamically adaptive storage strategy not only significantly improves the pertinence and effectiveness of food ingredient preservation, but also ensures that various food ingredients are stored under the best magnetic field conditions, thus effectively extending the freshness and shelf life of the food ingredients.
[0036] In step S1, the attribute characteristics refer to a series of characteristics or parameters possessed by the food ingredients themselves, and these characteristics or parameters can reflect the properties related to food ingredient preservation.
[0037] In one embodiment, the attribute characteristics include at least one of the price, nutritional components, calories, preference degree, and freshness of the food ingredients.
[0038] In step S1, the standard attribute characteristics refer to the ideal or recommended attribute characteristic values set to maintain the best preservation state of the food ingredients.
[0039] Among them, the difference in the attribute characteristics of the food ingredients is negatively correlated with their priority. Specifically, when the difference between the attribute characteristics of the food ingredients and their standard state is larger, the priority of the food ingredients in the preservation process is lower; conversely, when the difference is smaller, the priority is higher. The priority refers to the priority order or level corresponding to N kinds of food ingredients in the food ingredient preservation device.
[0040] In addition, in order to facilitate the rapid determination of priorities, the differences in the attribute characteristics of the ingredients can be measured by quantitative indicators. Specifically, several attribute characteristics of the ingredients are obtained, and the corresponding evaluation results (such as scores) are determined based on the differences between the attribute characteristics and the corresponding standard attribute characteristics; the importance coefficient corresponding to each attribute characteristic is determined according to user needs; the comprehensive evaluation result is determined based on the importance coefficient of the attribute characteristic and the corresponding evaluation result; the comprehensive evaluation results are sorted to determine the priority of the corresponding ingredients.
[0041] In step S1, the food preservation 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 food preservation device can be a refrigerator, a freezer, or a module in a refrigerator or a freezer, such as a fresh-keeping drawer.
[0042] 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 as 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, and the growth rate of ice crystals is higher than the migration rate of water molecules. The resulting ice crystals are smaller, resulting in less damage to cells, reducing the loss rate of juice in food, and allowing the nutrition and taste of food to 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.
[0043] In step S2, the target magnetic field strength refers to the magnetic field strength that the food preservation device hopes to achieve, and the target magnetic field strength is related to at least one of the type, quantity or state of the food in the food preservation device. In step S3, the actual magnetic field strength refers to the magnetic field strength value actually generated in the current food preservation device, which is the magnetic field strength currently detected at the storage unit.
[0044] On the one hand, the target magnetic field strength can be an independent value, which means that there is an optimal magnetic field strength value for a certain food or under a certain storage condition.
[0045] On the other hand, the target magnetic field strength may be a range, in which 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 impose any specific limitation on this.
[0046] In a specific embodiment, based on a preset mapping relationship, a plurality of target magnetic field intensities corresponding to a plurality of food types in the food preservation device are determined.
[0047] In step S3, the magnetic control component is a device or device component capable of generating and controlling a magnetic field.
[0048] In one embodiment, controlling the magnetic control component in the food preservation device in step S3 to make the actual magnetic field intensity generated by it match the target magnetic field intensity may specifically include the following steps.
[0049] Step S31, controlling the power supply to supply current to the magnetic control component, detecting and judging whether the actual magnetic field intensity in the food preservation device meets the target magnetic field intensity;
[0050] If not, jump to step S32 to adjust the magnitude and / or direction of the current supplied by the power supply to the magnetic control component.
[0051] In this way, by adjusting the magnitude and / or direction of the current in the magnetic field component, the corresponding magnetic field intensity is matched with the target magnetic field intensity. The adjustment method is flexible and the intelligent level is high, enabling users to more conveniently manage the food preservation process.
[0052] In a specific embodiment, obtain the minimum target magnetic field intensity and the maximum target magnetic field intensity corresponding to the target food; detect and judge whether the actual magnetic field intensity in the food preservation device is less than the minimum target magnetic field intensity; if so, increase the magnitude of the current supplied by the power supply to the magnetic control component until the actual magnetic field intensity falls within the range of the minimum target magnetic field intensity and the maximum target magnetic field intensity.
[0053] In another specific embodiment, obtain the minimum target magnetic field intensity and the maximum target magnetic field intensity corresponding to the target food; detect and judge whether the actual magnetic field intensity in the food preservation device is greater than the maximum target magnetic field intensity; if so, decrease the magnitude of the current supplied by the power supply to the magnetic control component until the actual magnetic field intensity falls within the range of the minimum target magnetic field intensity and the maximum target magnetic field intensity.
[0054] In one embodiment, the magnetic control component may include a first electromagnetic coil and a second electromagnetic coil, and the food preservation device is arranged between the first electromagnetic coil and the second electromagnetic coil.
[0055] Control the power supply to supply current to the first electromagnetic coil to generate a first magnetic field; control the power supply to supply current to the second electromagnetic coil to generate a second magnetic field, and the actual magnetic field intensity in the food preservation device is determined by the first magnetic field and the second magnetic field.
[0056] In a specific embodiment, when the actual magnetic field intensity in the food preservation device does not match the target magnetic field intensity, adjust the magnitude of the current supplied by the power supply to the first electromagnetic coil; and / or adjust the magnitude of the current supplied by the power supply to the second electromagnetic coil.
[0057] In a specific embodiment, when the actual magnetic field strength in the food preservation device does not match the target magnetic field strength, adjust the current direction of the power supply to the first electromagnetic coil; and / or adjust the current direction of the power supply to the second electromagnetic coil.
[0058] In another specific embodiment, adjust the current direction and magnitude of the current to the first electromagnetic coil, and / or adjust the current direction and magnitude of the current to the second electromagnetic coil, so that the actual magnetic field strength in the food preservation device matches the target magnetic field strength.
[0059] Based on this, as Figure 2 shown, in an embodiment, the part of step S3 that controls the magnetic control component in the food preservation device to generate an actual magnetic field strength that matches the target magnetic field strength may specifically include the following steps.
[0060] Step S311, control the power supply to supply current to the first electromagnetic coil, detect and determine whether the magnetic field strength corresponding to the first magnetic field meets the target magnetic field strength;
[0061] If not, then jump to step S312, control the power supply to supply current to the second electromagnetic coil to generate a second magnetic field, so that the actual magnetic field strength in the food preservation 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.
[0062] In this way, by first controlling the power supply to supply current to the first electromagnetic coil, detecting whether the corresponding actual magnetic field strength meets the preset target magnetic field strength, if not, further activating the second electromagnetic coil, and using the magnetic field superposition effect generated by it and the first electromagnetic coil, accurately adjust the actual magnetic field strength in the food preservation device to the target value, realizing flexible and precise control of the magnetic field strength, avoiding unnecessary resource waste, with strong pertinence and wide adaptability.
[0063] In an embodiment, 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.
[0064] In a specific embodiment, the target magnetic field strength includes a minimum target magnetic field strength and a maximum target magnetic field strength.
[0065] Based on this, as shown in Fig. 3(a), in a specific embodiment, step S3 may specifically include the following steps.
[0066] Step S321, obtain the minimum target magnetic field strength and the maximum target magnetic field strength corresponding to the target food;
[0067] Step S322, detect and determine whether the actual magnetic field strength in the food preservation device is less than the minimum target magnetic field strength;
[0068] If so, jump to step S323, and control the power supply module to supply a current with the same direction as that of the first electromagnetic coil to the second electromagnetic coil, so that the actual magnetic field intensity falls within the range of the minimum target magnetic field intensity and the maximum target magnetic field intensity.
[0069] In step S322, the actual magnetic field intensity in the food preservation device can be understood as the magnetic field intensity corresponding to the first magnetic field or the second magnetic field. When the magnetic field intensity generated by a single electromagnetic coil is less than the minimum target magnetic field intensity, a second electromagnetic coil is introduced.
[0070] In this embodiment, according to the operation corresponding to step S323, it can be seen that the current directions of the first electromagnetic coil and the second electromagnetic coil are the same, so the magnetic field directions of the corresponding first magnetic field and the second magnetic field are the same, enabling the first magnetic field and the second magnetic field to be superimposed on each other, and the corresponding magnetic field intensity to be enhanced, gradually approaching the minimum target magnetic field intensity.
[0071] It should be noted that step S323 can be understood as: controlling the power supply module to supply a preset first initial current value and a second initial current value to the first electromagnetic coil and the second electromagnetic coil respectively, and supplying a current with the same direction as that of the first electromagnetic coil to the second electromagnetic coil.
[0072] On the one hand, when the actual magnetic field intensity generated after the superposition of the first magnetic field and the second magnetic field is greater than the minimum target magnetic field intensity, there is no need to adjust the current in the first electromagnetic coil and / or the second electromagnetic coil.
[0073] On the other hand, when the actual magnetic field intensity generated after the superposition of the first magnetic field and the second magnetic field is less than the minimum target magnetic field intensity, it indicates that the actual magnetic field intensity after the superposition of the first magnetic field and the second magnetic field with the same magnetic field direction still has not reached the minimum target magnetic field intensity. At this time, increase the magnitude of the current supplied by the power supply to the first electromagnetic coil, and / or increase the magnitude of the current supplied by the power supply to the second electromagnetic coil until the actual magnetic field intensity falls within the range of the minimum target magnetic field intensity and the maximum target magnetic field intensity.
[0074] In another specific embodiment, as shown in Fig. 3(b), step S3 may specifically include the following steps.
[0075] Step S331, obtain the minimum target magnetic field intensity and the maximum target magnetic field intensity corresponding to the target food;
[0076] Step S332, detect and determine whether the actual magnetic field intensity in the food preservation device is greater than the maximum target magnetic field intensity;
[0077] If so, jump to step S333, and control the power supply module to supply a current with a direction opposite to that of the first electromagnetic coil to the second electromagnetic coil, so that the actual magnetic field intensity falls within the range of the minimum target magnetic field intensity and the maximum target magnetic field intensity.
[0078] In this way, by adjusting the current directions of the first electromagnetic coil and the second electromagnetic coil, the precise control of the actual magnetic field intensity in the food preservation device is realized. The control method is flexible, easy to implement, and has strong robustness.
[0079] In step S332, the actual magnetic field intensity in the food preservation device can be understood as the magnetic field intensity corresponding to the first magnetic field or the second magnetic field. When the magnetic field intensity generated by a single electromagnetic coil is greater than the target magnetic field intensity, a second electromagnetic coil is introduced.
[0080] In this embodiment, according to the operations corresponding to step S333, it can be seen that the current directions of the first electromagnetic coil and the second electromagnetic coil are opposite, so the magnetic field directions of the corresponding 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 intensity is weakened.
[0081] It should be noted that step S333 can be understood as: controlling the power supply module to supply a preset first initial current value and a second initial current value to the first electromagnetic coil and the second electromagnetic coil respectively, and supplying a current with a direction opposite to that of the first electromagnetic coil to the second electromagnetic coil.
[0082] On the one hand, when the actual magnetic field intensity generated after the first magnetic field and the second magnetic field cancel each other out falls within the range of the minimum target magnetic field intensity and the maximum target magnetic field intensity, there is no need to adjust the current in the first electromagnetic coil and / or the second electromagnetic coil.
[0083] On the other hand, when the actual magnetic field intensity generated after the first magnetic field and the second magnetic field cancel each other out is greater than the maximum target magnetic field intensity, it indicates that the actual magnetic field intensity after the first magnetic field and the second magnetic field with opposite magnetic field directions cancel each other out still exceeds the maximum target magnetic field intensity. At this time, reduce the magnitude of the current supplied by the power supply to the first electromagnetic coil, and / or reduce the magnitude of the current supplied by the power supply to the second electromagnetic coil until the actual magnetic field intensity falls within the range of the minimum target magnetic field intensity and the maximum target magnetic field intensity.
[0084] In one embodiment, step S2 may specifically include the following steps.
[0085] Step S2', select those with a large difference between the attribute characteristics and the corresponding standard attribute characteristics as high priority, and use the magnetic field intensity corresponding to the target food material with the highest priority as the target magnetic field intensity of the food preservation device.
[0086] In addition, when the ingredients in the food preservation device change, the target magnetic field intensity is updated. In a specific embodiment, as shown in Fig. 4(a), the control method may specifically include the following steps.
[0087] Step S411, determining whether the target ingredients in the food preservation device have been completely consumed;
[0088] If so, jump to step S412 to re - rank the priorities of the remaining ingredients in the food preservation device, determine and update the target ingredients and the corresponding target magnetic field intensity.
[0089] In another specific embodiment, as shown in Fig. 4(b), the control method may specifically include the following steps.
[0090] Step S421, determining whether new types of ingredients appear in the food preservation device;
[0091] If so, jump to step S422 to re - rank the priorities of all the ingredients in the food preservation device, determine and update the target ingredients and the corresponding target magnetic field intensity.
[0092] In this way, the target magnetic field intensity is dynamically updated according to the changes in the ingredients in the food preservation device, enabling the food preservation device to provide the most suitable preservation conditions for the currently stored ingredients, thereby effectively extending the freshness and shelf life of the ingredients.
[0093] In this embodiment, when all the ingredients with the highest priority are consumed, the food preservation device prompts the user to delete the ingredients with the highest priority. At this time, the priorities of the remaining ingredients are re - ranked, and according to the latest ranking result, the target magnetic field intensity of the ingredients with the highest priority is set.
[0094] As Figure 5 shown, an embodiment of the present invention provides a food preservation device 100.
[0095] The food preservation device 100 includes a first electromagnetic coil 11 for generating a first magnetic field. On the one hand, the first magnetic field is used to preserve the ingredients in the food preservation device 100. On the other hand, the first magnetic field indirectly affects the actual magnetic field intensity in the food preservation device by influencing a second component.
[0096] The food preservation device 100 includes a second component disposed within the range of the first magnetic field generated by the first electromagnetic coil 11. The second component includes a second electromagnetic coil 12 and a storage unit 13. The second electromagnetic coil 12 is disposed at the storage unit 13, and the storage unit 13 is used for placing ingredients.
[0097] In one embodiment, when the second electromagnetic coil 12 is energized, the second electromagnetic coil 12 generates a second magnetic field. The superposition or cancellation of the first magnetic field and the second magnetic field forms a third magnetic field within the food preservation device 100. The magnetic field intensity of the third magnetic field is related to the magnetic field intensities and magnetic field directions of the first magnetic field and the second magnetic field.
[0098] Specifically, when the magnetic field intensity of the third magnetic field does not match the target magnetic field intensity, the magnetic field intensity and / or direction of the first magnetic field is adjusted by controlling the current direction and / or current intensity applied to the first electromagnetic coil 11. And / or, the magnetic field intensity and / or direction of the second magnetic field is adjusted by adjusting the current direction and / or current intensity applied to the second electromagnetic coil 12 until the actual magnetic field intensity of the third magnetic field matches the target magnetic field intensity.
[0099] In one embodiment, the food preservation device 100 further includes a circuit module. The first end of the second electromagnetic coil 12 is connected to the first end of the circuit module, and the second end of the second electromagnetic coil 12 is connected to the second end of the circuit module to form a closed loop, which is disposed at the storage unit 13.
[0100] When the first electromagnetic coil 11 is energized, the first electromagnetic coil 11 generates a first magnetic field, which covers and passes through the closed loop, generating an induced current in the closed loop and thus generating a second magnetic field.
[0101] Specifically, when the actual magnetic field intensity corresponding to the third magnetic field matches the target magnetic field intensity, it means that the magnetic field environment of the food preservation device 100 has reached the ideal preservation condition, and at this time, no additional adjustment of the current in the closed loop is required. When the magnetic field intensity of the third magnetic field does not match the target magnetic field intensity, the magnetic field intensity and / or direction of the second magnetic field is adjusted by controlling the magnitude and / or direction of the current in the closed loop.
[0102] Since the third magnetic field is the result of the superposition of the first magnetic field and the second magnetic field, adjusting the second magnetic field will directly affect the magnetic field intensity of the third magnetic field, thereby enabling the actual magnetic field intensity of the third magnetic field to gradually approach and match the target magnetic field intensity.
[0103] The food preservation device 100 further includes a control module, which is used to implement a food preservation control method.
[0104] In a specific embodiment, the food preservation control method can adopt the control method described above.

[0108] The computer-readable storage medium may include: a flash drive, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, an optical disc, etc.

This dynamically adaptive preservation strategy not only significantly improves the pertinence and effectiveness of food preservation, but also ensures that various foods can be stored under the optimal magnetic field conditions, thereby effectively extending the freshness and shelf life of the food and improving the preservation efficiency.
