Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to an air supply control method, a refrigeration device and a medium. Background Art

[0002] In food storage devices, such as refrigerators and freezers, effective air supply control is essential to maintain the freshness of food and extend its shelf life. Traditional air supply control methods mainly rely on preset fixed programs or manual adjustments by users. These methods fail to fully consider the actual conditions of food storage, especially the changes in food capacity. When the amount of food stored is small, excessive air supply not only wastes energy, but may also accelerate the drying and dehydration of food, affecting the preservation effect; conversely, when the food is fully loaded, if the air supply is insufficient, it may lead to uneven temperature distribution among the food, and the temperature in some areas is too high, which also affects the preservation quality of the food.

[0003] In the prior art, air volume control is mostly adjusted based on the feedback from temperature sensors, and the temperature of the storage space is monitored to indirectly determine whether the air volume needs to be adjusted. However, this method ignores the key factor of the dynamic changes of food, because even if the overall temperature of the storage space remains constant, the food in different storage states has completely different requirements for cooling air.

[0004] In addition, the amount of food stored can be monitored through a weight sensor, but this method not only increases the cost, but also, when the types and densities of food are diverse, the weight cannot accurately reflect the actual demand of food for cooling. The above methods fail to achieve adaptive air volume adjustment based on the actual storage conditions of food, resulting in unsatisfactory food preservation effects and low energy efficiency. Summary of the invention

[0030] 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.

[0033] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] 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.

[0035] like Figure 1 As shown, an embodiment of the present invention provides a storage device 100. The storage device 100 includes a first component 11, and the first component 11 includes a first electromagnetic coil 11-1 for generating a first magnetic field.

[0036] Continue to refer to Figure 1As shown in a specific embodiment, the first component 11 includes a first cover plate (or upper cover plate) 11-2 and a second cover plate (or lower cover plate) 11-3, and the first electromagnetic coil 11-1 is arranged between the upper cover plate 11-2 and the lower cover plate 11-3. Figure 2 The plane structure shown is arranged parallel to the upper position of the storage unit 12-2. Of course, it can also be arranged at a certain angle to the upper position of the storage unit 12-2, and the present invention does not make any specific limitation on this.

[0037] As shown in Figures 3(a) and 3(b), in a specific embodiment, the first component 11 includes a base 11-4 and a plurality of second cover plates 11-5, and a first electromagnetic coil 11-1 is provided between the base 11-4 and the corresponding second cover plates 11-5. In this embodiment, the second cover plate 11-5 can fix the first electromagnetic coil 11-1 on the base 11-4 to prevent it from jumping, so as to avoid the position of the first electromagnetic coil 11-1 changing and causing uneven magnetic field distribution, thereby affecting the preservation effect or detection accuracy of the food. Through the design of multiple second cover plates 11-5, the second cover plates 11-5 can be flexibly installed or removed according to different storage environments or needs, thereby adjusting the number and layout of the first electromagnetic coils 11-1.

[0038] In the above embodiment, the number and layout of the first electromagnetic coils 11-1 can be set accordingly based on the number and positions of the storage units 12-2 in the second component 12. In other words, if there is one storage unit 12-2 in the second component 12, one first electromagnetic coil 11-1 is set at a corresponding position above the storage unit 12-2; if there are two storage units 12-2 in the second component 12, two first electromagnetic coils 11-1 are set at corresponding positions above the storage unit 12-2. Of course, if the magnetic field generated by setting one first electromagnetic coil 11-1 can cover multiple storage units 12-2, only one first electromagnetic coil 11-1 can be set in the first component 11, and the present invention does not make specific restrictions on this.

[0039] In the above embodiment, when the first component 11 includes a plurality of first electromagnetic coils 11-1, all the first electromagnetic coils 11-1 are connected in parallel to the power supply of the storage device 100. By connecting the power supply in parallel, each first electromagnetic coil 11-1 can be powered independently, thereby generating its own magnetic field, and these magnetic fields can form a uniformly distributed magnetic field area under the joint action of the base 11-4 and the second cover plate 11-5.

[0040] Continue to refer to Figure 1As shown, the storage device 100 further includes a second component 12, which is arranged within the range of the first magnetic field and includes a second electromagnetic coil 12-1 and a storage unit 12-2. The storage unit 12-2 is used to place food, and the second electromagnetic coil 12-1 is arranged at the storage unit 12-2; when the food at the storage unit 12-2 changes, the second electromagnetic coil 12-1 obtains a second induced current and generates a second magnetic field, and the first electromagnetic coil 11-1 obtains a first induced current corresponding to the second magnetic field.

[0041] In one embodiment, the second component 12 includes a closed loop, and the closed loop is arranged at the first storage unit in the storage device 100. Of course, the second component 12 may also include multiple closed loops and corresponding multiple storage units, each closed loop is arranged at a corresponding storage unit, and the number of closed loops and storage units is not specifically limited.

[0042] As shown in Figure 4(a), in a specific embodiment, the second component 12 includes a first identification component 12-5, a first end of the first identification component 12-5 is connected to the first end of the second electromagnetic coil 12-1, and a second end of the first identification component 12-5 is connected to the second end of the second electromagnetic coil 12-1 to form a first closed loop 12-4.

[0043] In a specific embodiment, the identification component 12-5 is integrated into a circuit control unit, based on which the first end of the circuit control unit is connected to the first end of the second electromagnetic coil 12-1, and the second end of the circuit control unit is connected to the second end of the second electromagnetic coil 12-1 to form a closed loop. In this embodiment, the circuit control unit can not only capture and collect the induced current, but also improve the system integration and reliability of the entire storage device.

[0044] In a specific embodiment, the first storage unit can be placed close to the first closed loop 12-4 or a cover plate can be provided between the first storage unit and the first closed loop 12-4. In this embodiment, there is no distance between the storage unit and the closed loop, and the first magnetic field can act more directly on the items placed in the storage unit, thereby achieving a better preservation effect.

[0045] As shown in FIG4(b), in a specific embodiment, the storage device 100 further includes a first support member 13, a second support member 14 and a third support member 15. The support members are all fixedly arranged at the inner wall of the storage device 100, and are used to support the first component 11; the second component 12 may also include a first storage unit 12-6 and a second storage unit 12-7, wherein the first storage unit 12-6 is arranged between the first support member 13 and the second support member 14, and the second storage unit 12-7 is arranged between the second support member 14 and the third support member 15.

[0046] The first placement unit 12 - 6 is disposed within the range of the magnetic field generated by the first electromagnetic coil 11 - 1 , and the second placement unit 12 - 7 is disposed within the range of the magnetic field generated by the third electromagnetic coil 11 - 4 .

[0047] The first storage unit 12-6 in the second component 12 is connected to the corresponding second electromagnetic coil to form a first closed loop 12-8. Similarly, the second storage unit 12-7 in the second component 12 is connected to the corresponding second electromagnetic coil to form a second closed loop 12-9.

[0048] The first storage unit 12-6 can be configured to be pulled forward and backward in the storage device 100 to open or close the first storage unit 12-6, and the second storage unit 12-7 can be configured to be pulled forward and backward in the storage device 100 to open or close the second storage unit 12-7.

[0049] In this embodiment, the second support member 14 is used to effectively separate the first storage unit 12-6 and the second storage unit 12-7, so that the two storage units are physically independent of each other, thereby meeting different storage needs or environmental requirements. In addition, the first support member 13 and the second support member 14 together provide a stable spatial structure for the first storage unit 12-6, so that it can be firmly installed inside the storage device 100. Similarly, the second support member 14 and the third support member 15 together provide a stable spatial structure for the second storage unit 12-7. Such a design can not only ensure the structural stability of the storage device 100, but also meet the needs of partitioned storage.

[0050] Continuing to refer to FIG. 4( b ), the second support member 14 includes a support base 14-1 and a filling cavity 14-2 mounted on the support base 14-1, wherein the support base 14-1 is fixedly disposed in the partition storage device 100, and a magnetically resistive filler is filled in the filling cavity 14-2. By disposing the magnetically resistive filler in the second support member 14, the first magnetic field and the second magnetic field between the first placement unit 12-6 and the second placement unit 12-7 can be effectively isolated to avoid interference.

[0051] Continuing to refer to FIG. 4( b ), in a specific embodiment, the first component 11 includes a first cover plate 11-2 and a second cover plate 11-3, the first electromagnetic coil 11-1 is disposed at a first position between the first cover plate 11-2 and the second cover plate 11-3, the third electromagnetic coil 11-4 is disposed at a second position between the first cover plate 11-2 and the second cover plate 11-3, and the first position and the second position are different. The first position is located above the first storage unit 12-6, and the second position is located above the second storage unit 12-7.

[0052] Continuing with reference to FIG. 4( b ), in a specific embodiment, the first component 11 forms an assembly relationship with at least two of the first support member 13 , the second support member 14 and the third support member 15 to form storage space for the first storage unit 12 - 6 and / or the second storage unit 12 - 7 .

[0053] Specifically, the first end of the first component 11 contacts and fixes with the first end of the first support member 13, which can be achieved by mounting holes, buckles, bolts or other fastening methods, or overlapped at the first end of the first support member 13, and the second end of the first support member 13 is fixedly set at the corresponding inner tank of the storage device; the second end of the first component 11 contacts and fixes with the first end of the second support member 14, or overlapped at the first ends of the second support member 14 and; and / or, the second end of the first component 11 contacts and fixes with the first end of the third support member 15, or overlapped at the first ends of the third support member 15 and. The second end 14 of the second support member and the second end of the third support member 15 are both fixedly set at the corresponding inner tank of the storage device.

[0054] In one embodiment, in the vertical direction, the first support member 13, the second support member 14 and the third support member 15 have the same height. In this way, by setting the equal heights, it is not only possible to ensure that the support members are evenly distributed in the vertical direction, thereby providing a stable supporting force; it also helps to ensure the even distribution of the magnetic field in the vertical direction, thereby increasing the efficiency and consistency of the interaction between the magnetic field and the closed loop. In addition, in other embodiments, the first component 11 can also be directly fixed to the corresponding inner tank of the storage device 100.

[0055] 3, in one embodiment, the first component 11 further includes an anti-interference component 11-3, which is disposed between the first electromagnetic coil 11-1 and the third electromagnetic coil 11-4. The anti-interference component 11-3 is used to prevent magnetic field interference between the first electromagnetic coil 11-1 and the second electromagnetic coil 11-4.

[0056] Continuing with reference to FIG. 4(b), when the first component 11 is powered on, the first component 11 generates a first magnetic field, which covers and passes through the first closed loop 12-4 formed by the first electromagnetic coil 1 in the second component 12 and the first storage unit connected thereto. Based on Faraday's law of electromagnetic induction, when the magnetic flux passing through the first closed loop 12-4 changes, an induced electromotive force is generated in the first electromagnetic coil 1, and this induced electromotive force drives the free electrons in the first closed loop 12-4 to move, thereby forming an induced current (i.e., a second induced current) in the second electromagnetic coil 12-1. The second induced current generates a second magnetic field, which interacts with the first magnetic field. When the food at the first storage unit changes, the second magnetic field will change accordingly, thereby generating an induced current (i.e., a first induced current) in the first electromagnetic coil 11-1.

[0057] like Figure 1 As shown, the storage device 100 further includes an air supply device and a control module, wherein the air supply device includes an air supply port 16 facing the storage unit. The control module is coupled to the air supply device and is used to implement an air supply control method.

[0058] In a specific embodiment, an air supply control method can refer to the method described below, and its corresponding effects can also refer to the embodiments or specific embodiments described below.

[0059] like Figure 5 As shown, an air supply control method is provided in one embodiment of the present invention.

[0060] The air supply control method can be used to adjust the air supply volume of the storage device.

[0061] The storage device refers to a device or container specifically used to store, preserve and manage 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 freezer, such as a fresh-keeping drawer.

[0062] In one embodiment, the storage device may be configured as described above, and the corresponding technical solution may be referenced in the air supply control method provided in the present invention.

[0063] like Figure 5 As shown, an embodiment of the present invention provides an air supply control method, comprising the following steps.

[0064] Step S1, obtaining a first induced current at a first electromagnetic coil;

[0065] Step S2: controlling the air supply volume of the air supply device according to the first induced current.

[0066] In this way, by using the first magnetic field generated by the first electromagnetic coil to act on the second component, a second induced current is generated, and the induced current drives the second electromagnetic coil to generate a second magnetic field, thereby inducing the first induced current in the first electromagnetic coil. By detecting this current change, the actual storage state of the food can be indirectly sensed, and the air supply of the air supply device can be automatically adjusted accordingly to ensure that the temperature distribution in the storage space is uniform and adaptable, effectively avoiding the problem of food preservation caused by excessive or insufficient air supply, which not only improves the quality of food preservation, but also achieves efficient use of energy.

[0067] In step S1, the first electromagnetic coil can generate a first magnetic field, which is used to preserve the food in the storage device on the one hand, and to indirectly locate the storage unit where the food changes by affecting the second component on the other hand.

[0068] 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.

[0069] In step S2, the air supply device may include a blower, a fan, etc.

[0070] It should be noted that when the food in the storage unit changes (such as weight, position, etc.), this change will affect the magnetic field environment of the second electromagnetic coil, thereby generating a second induced current in the second electromagnetic coil and generating a second magnetic field. This second magnetic field will act on the first electromagnetic coil, thereby generating an induced current (i.e., the first induced current) in the first electromagnetic coil again.

[0071] Specifically, the second component includes a closed loop, in which the first magnetic field acts. When the food at the storage unit changes, the number of magnetic field lines passing through the closed loop changes, and then the magnetic flux in the closed loop changes, thereby generating a second induced current on the second electromagnetic coil.

[0072] In one embodiment, the closed loop may be generated by the second electromagnetic coil itself, and the second induced current at the second electromagnetic coil may be measured by using a current measuring tool.

[0073] In another embodiment, the closed loop can also be formed by interconnecting the second electromagnetic coil and the identification component. In this embodiment, the closed loop is arranged at the storage unit, and when the food at the storage unit changes, the identification component can obtain the second induced current and output an identification signal.

[0074] It should be noted that when two or more current sources act on the same magnetic field area at the same time, the magnetic field or current effects they produce can be superimposed. This means that each current source independently contributes its magnetic field or current effect, and these effects can be added in space.

[0075] Based on this, in one embodiment, the first induced current represents the superposition of an initial current corresponding to the first magnetic field and the second induced current.

[0076] The above embodiment shows that when the second electromagnetic coil generates the second induced current, the second induced current not only affects the magnetic field around the second electromagnetic coil, but also affects the first electromagnetic coil through the interaction of the magnetic field. This influence causes the current in the first electromagnetic coil to change, and the changed current (i.e., the first induced current) is the result of the combined action of the initial current and the second induced current.

[0077] like Figure 6 As shown, in one embodiment, step S2 may specifically include the following steps.

[0078] Step S21, obtaining an initial current flowing to the first electromagnetic coil;

[0079] Step S22: adjusting the air supply volume of the air supply device according to the numerical relationship between the initial current and the first induced current, and / or whether the first induced current reaches a preset threshold.

[0080] In step S21, the initial current refers to the current originally existing in the first electromagnetic coil in the absence of other external interference or changes, and the initial current is used to generate the first magnetic field.

[0081] In step S22, the first induced current is an indirect result of the influence of the change of the food on the first magnetic field environment, and the second induced current is a direct result of the influence of the change of the food on the first magnetic field environment. In other words, when the food at the storage unit does not change, the second electromagnetic coil will not generate a changing magnetic flux under the action of the constant first magnetic field, and thus will not generate a second induced current, and thus will not generate an induced current due to the action of the second magnetic field, so the first induced current at the first electromagnetic coil may retain the initial current.

[0082] like Figure 7 As shown, in a specific embodiment, step S22 may specifically include the following steps.

[0083] Step S221, determining whether the first induced current is equal to the initial current;

[0084] If yes, jump to step S222A to turn off the air supply device to stop supplying air to the storage device;

[0085] If not, jump to step S222B. When the first induced current is greater than or equal to the preset threshold, control the air supply device to supply air to the storage device with a preset first duty cycle; when the first induced current is less than the preset threshold, control the air supply device to supply air to the storage device with a preset second duty cycle.

[0086] In this way, by comparing the numerical relationship between the first induced current and the initial current at the first electromagnetic coil, the air supply volume of the air supply device is adaptively adjusted, and the degree of intelligence is high.

[0087] In a specific embodiment, the first duty cycle is 100% and the second duty cycle is 50%.

[0088] In one embodiment, after step S2, the method further includes the following steps.

[0089] Step S3, obtaining the current compartment temperature in the storage device, and when the compartment temperature is less than or equal to the standard temperature, turning off the air supply device to stop supplying air to the storage device.

[0090] In this way, by detecting the room temperature, it can be ensured that the current blowing volume has met the demand, so that the air supply can be stopped in time, which can not only reduce energy consumption but also avoid excessive blowing that affects the quality of stored food.

[0091] In addition, before the first electromagnetic coil generates the first magnetic field, it is necessary to energize the first electromagnetic coil. For the storage device, the closing of the door of the storage device can be used as a sign of energizing the first electromagnetic coil.

[0092] Based on this, in one embodiment, before step S1, the control method may further include the following steps.

[0093] Step P11, detecting a first brightness value and a second brightness value of a storage device corresponding to a first moment and a second moment within a unit time;

[0094] Step P12, determining whether the first brightness value is greater than the second brightness value;

[0095] If yes, jump to step P13 to determine whether the storage device is opened at the first moment and the door of the storage device is closed at the second moment;

[0096] Step P14, when the storage device door is closed, an initial current is provided to the first electromagnetic coil.

[0097] In this way, by detecting the brightness changes of the storage device per unit time, the switch state of the storage device door can be automatically determined, and the process of energizing the first electromagnetic coil can be triggered when the door is closed, thereby providing an accurate trigger signal for subsequent operations (such as magnetic field generation and air supply control), thereby realizing the intelligent linkage between storage device status monitoring and electromagnetic coil energization control.

[0098] In one embodiment, the brightness value in step P11 can be determined by a photoresistor sensor. Specifically, using the photoresistor sensor, when the change from light to dark inside the storage device is identified, it is determined that the door of the storage device is in a closed state. At this time, the power supply of the storage device is used to provide current (initial current) to the first electromagnetic coil. When the change from dark to light inside the storage device is identified, it is determined that the door of the storage device is in an open state. At this time, the power supply of the storage device is disconnected from providing current to the first electromagnetic coil.

[0099] In one embodiment, when the second component includes a first placement unit and a second placement unit, a third electromagnetic coil is provided at the first placement unit, and a fourth electromagnetic coil is provided at the second placement unit, the control method may further include the following steps.

[0100] Step M1, obtaining a third induced current at the third electromagnetic coil and a fourth induced current at the fourth electromagnetic coil;

[0101] Step M2: adjusting the ratio of the air supply volume of the air supply device to the first placement unit and the second placement unit according to the third induced current and the fourth induced current.

[0102] In this way, by acquiring the induced current at the third and fourth electromagnetic coils, the proportion of air supply from the air supply device to different storage units is intelligently adjusted, thereby achieving accurate distribution and dynamic balance of the air supply.

[0103] like Figure 8 As shown, in a specific embodiment, step M2 may specifically include the following steps.

[0104] Step M21, controlling the air supply device to supply air to the first storage unit at a first air supply volume, and to supply air to the second storage unit at a second air supply volume;

[0105] Step M22, when the third induced current is greater than or equal to the fourth induced current, controlling the first air supply volume to be greater than or equal to the second air supply volume;

[0106] Step M23, when the third induced current is smaller than the fourth induced current, controlling the first air supply volume to be smaller than the second air supply volume.

[0107] In this way, by comparing the induced currents of the third and fourth electromagnetic coils, the air supply to the first and second storage units is dynamically adjusted to ensure that the air supply matches the needs of each storage unit, thereby achieving intelligent and differentiated distribution of the air supply.

[0108] In step M22, when the third induced current (i.e., the induced current at the first storage unit) is greater than or equal to the fourth induced current (i.e., the induced current at the second storage unit), it indicates that the first storage unit may have undergone a major change (e.g., a lot of new food has been added). In order to maintain or restore the balance of temperature, humidity or other environmental parameters inside the two storage units, the control system will adjust the air supply volume so that the first air supply volume is greater than or equal to the second air supply volume. This ensures that the environment inside the first storage unit will not deteriorate due to the increase in food, and also helps to keep the environmental parameters between the two storage units relatively stable.

[0109] On the contrary, in step M23, when the third induced current is less than the fourth induced current, it indicates that the first storage unit may be relatively stable or the amount of food has decreased, while the second storage unit may have undergone a large change. In order to cope with this change, the control system will adjust the air supply volume so that the first air supply volume is less than the second air supply volume. This can ensure that the environment in the second storage unit is properly adjusted, and also help to maintain a balance between the environmental parameters of the two storage units.

[0110] For ease of understanding, Fig. 9 As shown, a fresh-keeping drawer 20 in a refrigerator is taken as an example. A plurality of fresh-keeping boxes 21 are placed in the fresh-keeping drawer 20. The fresh-keeping box 21 includes a box cover, a box body and a cover plate, a second electromagnetic coil and a closed loop formed by a circuit control module. The box cover and the box body can be combined to form a closed space for storing food. A power module and a photoresistor sensor are provided in the circuit module. The closed loop can be installed in the box cover through the cover plate. When the fresh-keeping box 21 is in use, it is placed in the fresh-keeping drawer of the refrigerator. If there is a fresh-keeping box 21 that is not in use, it is placed in other locations inside the refrigerator.

[0111] When the user puts the food into the fresh-keeping box 21 and places the fresh-keeping box 21 at the specified position of the refrigerator fresh-keeping drawer 20, and closes the refrigerator door, the sensitive resistor sensor recognizes the change from light to dark inside the refrigerator and determines that the refrigerator door is closed. At this time, the power supply at the refrigerator end provides current to the first electromagnetic coil 11-1, and detects the initial current intensity I1 of the first electromagnetic coil 11-1 in real time. The closed loop in the fresh-keeping box is closed. When the food changes at the storage unit, a second induced current is generated in the closed loop, and it affects the first component 11 on the upper part of the fresh-keeping box 21, and generates an induced current △I1 in the first electromagnetic coil 11-1.

[0112] When the current intensity I1 of the first electromagnetic coil 11-1 is detected in real time and remains unchanged, it indicates that no fresh-keeping box 21 has been placed in the fresh-keeping drawer 20. At this time, the air outlet of the refrigerator air supply device is closed and no cooling treatment is required. When the current intensity in the first electromagnetic coil 11-1 detected in real time exceeds the initial current intensity I1, it indicates that a fresh-keeping box 21 is placed in the fresh-keeping drawer 20, and the current intensity I1+△I1 of the first electromagnetic coil 11-1 is recorded. When I1+△I1 does not reach the threshold value Imax, it indicates that a certain number of fresh-keeping boxes 21 are placed in the fresh-keeping drawer 20. At this time, the refrigerator end controls the air supply system to supply air for cooling at a maximum air volume of 50%. When the temperature reaches the set temperature, the air supply is stopped.

[0113] When I1+△I1 reaches the threshold value Imax, it indicates that there are a large number of fresh-keeping boxes 21 placed in the fresh-keeping drawer 20 and rapid refrigeration is required. At this time, the refrigerator controls the air supply system to supply air for cooling at a maximum air volume of 100%. When the temperature reaches the set temperature, the air supply is stopped.

[0114] like Fig.10 As shown, an embodiment of the present invention provides a refrigeration device 200.

[0125] In summary, the present invention provides an air supply control method, refrigeration equipment and medium. By utilizing the first magnetic field generated by the first electromagnetic coil to act on the second component, a second induced current is generated, and the induced current drives the second electromagnetic coil to generate a second magnetic field, thereby inducing a first induced current in the first electromagnetic coil. By detecting this current change, the actual storage status of the food can be indirectly sensed, and the air supply of the air supply device can be automatically adjusted accordingly to ensure that the temperature distribution in the storage space is uniform and adaptable, effectively avoiding the problem of food preservation caused by excessive or insufficient air supply, which not only improves the preservation quality of the food, but also achieves efficient use of energy.
