[0002] In the field of food preservation technology, with the improvement of people's living standards and the increasing attention to food safety and health, efficient and reliable food preservation devices have become a hot demand in the market. Traditional food preservation methods mostly rely on temperature control or chemical preservatives, but these methods often have problems such as high energy consumption, unstable preservation effects, and potential impacts on human health. In order to overcome these shortcomings, in recent years, the use of magnetic field preservation technology has gradually attracted attention due to its environmental protection and high efficiency.

[0003] However, although magnetic field preservation technology has many advantages in theory, in practical applications, the food preservation devices in the prior art generally lack an intuitive feedback mechanism. Specifically, these devices can usually only perform preservation tasks silently, and cannot provide users with direct feedback on their working status or preservation effects. Users can often only judge the preservation effect by observing the changes in the appearance of the food or relying on experience, which is neither accurate nor timely.

[0004] In addition, due to the lack of effective status indication, users may encounter a series of problems when using these fresh-keeping devices. For example, users may not know exactly when to replace the consumables in the fresh-keeping device, or when the device needs maintenance. These problems not only affect the preservation effect of food, but also may reduce users' trust and satisfaction with the fresh-keeping device. Summary of the invention

[0034] In one embodiment, the food preservation device can be configured as described below.

[0035] The refrigeration device 200 may specifically be a computer device, and the computer device may be a terminal device or a server.

[0036] The refrigeration device 200 includes at least one processor, which may be a central processing unit (CPU) 21 .

[0037] 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.

[0038] 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.

[0040] An embodiment of the present invention provides a food preservation device 100 .

[0041] The food preservation device 100 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 100 can be a refrigerator, a freezer, or a module in a refrigerator or a freezer, such as a fresh-keeping drawer.

[0042] As shown in FIG2(a), the food preservation device 100 includes a first component for generating a first magnetic field. On the one hand, the first magnetic field is used to preserve the food in the food preservation device 100. On the other hand, the first magnetic field drives the indicator to mark whether the food in the storage unit is in an effective preservation state by driving the motor 13.

[0043] 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.

[0044] In one embodiment, the first component includes a first permanent magnet 11 and a second permanent magnet 12 , and the placement unit 14 is disposed between the first permanent magnet 11 and the second permanent magnet 12 .

[0045] In this embodiment, the first magnetic field is generated by the first permanent magnet 11 and the second permanent magnet 12. Since the permanent magnet has inherent magnetism and can continuously provide a magnetic field, the first magnetic field generated by it is not easily disturbed by the outside and can be considered relatively constant, so the first magnetic field is a constant magnetic field. In addition, the first component can generate the first magnetic field without an external power supply, which can reduce the energy consumption and operating cost of the device.

[0046] In a specific embodiment, as shown in FIG. 3( a ) and FIG. 3( b ), the magnetic poles of one end of the first permanent magnet 11 close to the placement unit 14 and the magnetic poles of one end of the second permanent magnet 12 close to the placement unit 14 are opposite.

[0047] In this way, a closed magnetic circuit can be formed, the magnetic field strength at the storage unit 14 can be enhanced, and the preservation efficiency can be improved. In addition, the opposite magnetic poles can also prevent the magnetic field from forming a region with large magnetic resistance at the storage unit 14, ensuring that all parts of the food can be affected by a uniform magnetic field, further improving the preservation effect.

[0048] Continue to refer to Figure 3(a) and 3(b) As shown, in this embodiment, the first magnetic field between the first permanent magnet 11 and the second permanent magnet 12 is distributed in the first direction 802, and the storage unit 14 moves from the first end to the second end or from the second end to the first end along the second direction 801, thereby cutting the magnetic induction line and causing the magnetic flux of the closed loop formed by the motor 13 to change, thereby generating an induced current in the closed loop.

[0049] In a specific embodiment, the first permanent magnet 11 is disposed above the second permanent magnet 12. Figure 3(a) and 3(b) The distance between the placement unit 14 and the first permanent magnet 11 is equal to the distance between the placement unit 14 and the second permanent magnet 12 .

[0050] Thus, this vertically symmetrical layout helps to form a uniform and stable magnetic field environment in the storage unit 14. The equidistant setting ensures that each part of the food is uniformly affected by the magnetic field, avoiding differences in the preservation effect caused by uneven magnetic field distribution.

[0051] In other embodiments, the first permanent magnet 11 and the second permanent magnet 12 may also be disposed on the left and right sides of the storage unit 14. Figure 4(a) and 4(b) The distance between the placement unit 14 and the first permanent magnet 11 is equal to the distance between the placement unit 14 and the second permanent magnet 12 .

[0052] Of course, the first distance between the storage unit 14 and the first permanent magnet 11 and the second distance between the storage unit 14 and the second permanent magnet 12 are not necessarily equal. Specifically, the first distance can be greater than the second distance, that is, the storage unit 14 is closer to the second permanent magnet 12; similarly, the first distance can also be less than the second distance, that is, the storage unit 14 is closer to the first permanent magnet 11. The present invention does not impose specific limitations on this.

[0053] In other embodiments, the first component may also include other types of magnets or electromagnetic coils, and the first magnetic field is generated by supplying electricity to the first component, which is not specifically limited in the present invention.

[0054] The food preservation device 100 includes a storage unit 14, which is used to place food. For example, the storage unit 14 is a fresh-keeping box.

[0055] In one embodiment, the first magnetic field includes a magnetic field component along a first direction. The storage unit 14 is arranged in the first direction of the first component, which means that the food in the storage unit 14 will be directly affected by the magnetic field component along the first direction, ensuring that the food can be effectively preserved by the magnetic field.

[0056] The second direction forms an angle with the first direction, which means that the placement unit 14 does not move along the direction of the magnetic flux lines of the first magnetic field, but cuts the magnetic flux lines at an angle.

[0057] In a specific embodiment, the second direction forms an angle of 90° with the first direction.

[0058] In this way, by moving the storage unit in a second direction that is 90° to the first direction, the space can be maximized, while ensuring that the hard wire generates the maximum induced current when cutting the magnetic flux line. This design not only improves the efficiency of energy conversion, but also makes the structure of the entire device more compact and reasonable.

[0059] The food preservation device 100 includes a motor 13 , which is fixed to the storage unit 14 . A first end of the motor 13 is coupled to a second end thereof to form a closed loop for inducing a first magnetic field and generating an induced current.

[0060] In this embodiment, "coupling" does not mean that the entire closed loop is completely composed of electrical components inside the motor 13. In fact, the "coupling" here means that one end of the motor 13 is connected to the other end through an external wire or other electrical connector, thereby forming a closed loop in which current can flow.

[0061] The food preservation device 100 includes an indicator, a first end of which is fixed to the output shaft of the motor 13 for providing intuitive feedback on the food preservation status.

[0062] In a specific embodiment, the indicator is a spring, and the first end of the spring is fixedly connected to the output shaft of the motor 13. This means that when the motor 13 is started, its output shaft will rotate or generate some form of mechanical movement (such as horizontal movement), and this movement will be directly transmitted to the first end of the spring, thereby causing the spring to deform or move.

[0063] In one embodiment, the food preservation device 100 may further include a transmission gear, a first end of which is fixed to the output shaft of the motor 13, and a second end of which is engaged with the indicator. The transmission gear is used to adjust the movement speed or required driving force of the indicator to ensure that the indicator can move at an appropriate speed and force.

[0064] In one embodiment, the food preservation device 100 may further include at least one of a hard wire and a circuit module.

[0065] The hard wire is used to establish a stable current transmission path inside or outside the food preservation device 100, which can effectively transmit current and has the characteristics of stable structure. The circuit module is used to process input signals, perform logical operations, and output control signals to drive other components.

[0066] In a specific embodiment, the first end of the motor 13 is connected to the first end of the hard wire, and the second end of the motor 13 is connected to the second end of the hard wire. In this embodiment, the closed loop is formed by the interconnection of the motor 13 and the hard wire.

[0067] In another specific embodiment, the first end of the motor 13 is connected to the first end of the circuit module, and the second end of the motor 13 is connected to the second end of the circuit module. In this embodiment, the closed loop is formed by the interconnection of the motor 13 and the circuit module.

[0068] In another specific embodiment, the first end of the motor 13 is connected to the first end of the hard wire, the second end of the hard wire is connected to the first end of the circuit module, and the second end of the circuit module is connected to the second end of the motor 13. In this embodiment, a closed loop is formed by connecting the motor 13, the hard wire and the circuit module in pairs.

[0069] In this embodiment, the circuit module, the motor 13 and the hard wire can be installed at the body of the storage unit 14. For example, the storage unit 14 is a fresh-keeping drawer. Figure 5 As shown, the fresh-keeping drawer 300 includes a drawer body 31 for placing food; a drawer decoration 32, which is arranged on the periphery of the drawer body 31 and is used to provide additional functions (for example, for fixing indicators); a drawer front cover 34, which is arranged on the front end of the drawer body 31 and is used to open or close the drawer; and a drawer frame 33, which is fixed on all sides of the drawer body 31 and is used to protect the internal structure of the drawer.

[0070] In this embodiment, the drawer front cover 34, the drawer frame 33 and the drawer decoration 32 are assembled with the drawer body 31. The first permanent magnet 11 and the second permanent magnet 12 are respectively arranged at the upper and lower positions of the fresh-keeping drawer 300. Specifically, the first permanent magnet 11 can be arranged above the drawer body 31, close to the top of the fresh-keeping drawer 300 or a fixed position above the drawer 300; the second permanent magnet 12 is correspondingly arranged below the drawer body 31, close to the bottom of the fresh-keeping drawer 300 or a fixed position below the drawer 300.

[0071] Continue to refer to Figure 5 As shown, the hard wire 37 is arranged around the drawer body 31, the first end of the hard wire 37 is connected to the first end of the circuit module 36, and the second end of the circuit module 36 is connected to the motor 13 to form a closed loop. The output shaft of the motor 13 is connected to the transmission gear 38, and one end of the transmission gear 38 is meshed with the spring 39 (i.e., the indicator).

[0072] Under this setting, the first permanent magnet 11 and the second permanent magnet 12 will generate a constant magnetic field from top to bottom or from bottom to top, as shown in Figures 3(a) and 3(b). The magnetic flux lines will be perpendicular to the moving direction of the drawer, pointing from the north pole of the magnet to the south pole. When the fresh-keeping drawer is pulled out or pushed in horizontally, it will cut these magnetic flux lines perpendicular to the moving direction and generate induced current.

[0073] Of course, the first permanent magnet 11 and the second permanent magnet 12 can also be arranged on both sides of the fresh-keeping drawer. Specifically, the first permanent magnet 11 can be arranged on one side of the fresh-keeping drawer, such as the left side; and the second permanent magnet 12 can be arranged on the other side of the drawer, i.e., the right side, as shown in Figures 4(a) and 4(b).

[0074] Under this setting, the first permanent magnet 11 and the second permanent magnet 12 will generate a constant magnetic field from left to right or from right to left. The magnetic flux lines will be parallel to the side of the drawer, pointing from the north pole (N pole) of the magnet to the south pole (S pole). The moving direction of the drawer needs to form a certain angle with the direction of the magnetic flux lines to cut these magnetic flux lines to form an induced current.

[0075] A groove is provided at the drawer decoration, and the motor 13 is fixed in the groove.

[0076] In one embodiment, when the storage unit 14 moves along the second direction and the indicator is actuated, the food in the storage unit 14 has been kept fresh.

[0077] In one embodiment, when the storage unit 14 moves along the second direction and the indicator does not move, the food in the storage unit 14 is not kept fresh.

[0078] In order to facilitate understanding of the process of the indicator action, continue to refer to Figures 2(a), 2(b) and Figure 5 As shown, for example, taking the fresh-keeping drawer 300 as an example, the fresh-keeping drawer 300 is arranged between the first permanent magnet 11 and the second permanent magnet 12. Under the action of the first permanent magnet 11 and the second permanent magnet 12, there is a first magnetic field in the fresh-keeping drawer 300; a closed loop formed by a motor 13 and a hard wire 37 is arranged on the drawer body 31 of the fresh-keeping drawer.

[0079] When the user uses the fresh-keeping drawer 300, the user pulls out the fresh-keeping drawer 300, and the hard wire 37 fixed on the fresh-keeping drawer body 31 follows the drawer to run at the same speed. Since the fresh-keeping drawer 300 moves between the first permanent magnet 11 and the second permanent magnet 12, the hard wire 37 cuts the magnetic field induction line of the first magnetic field, generating an induced current in the closed loop.

[0080] When the induced current flows in the closed loop, it drives the motor 13 to rotate. The output shaft of the motor 13 is connected to the indicator 39 (e.g., a spring), so the indicator 39 responds to the rotation of the motor 13 and performs corresponding actions, such as telescoping, rotating, or swinging the light. The specific action form is based on the type of motor 13, the design of the indicator 39, and the connection method between them. When the indicator 39 is in action, it indicates that the food in the fresh-keeping drawer 300 is already in a fresh-keeping state.

[0081] When the user finishes using the fresh-keeping drawer 300, the user pushes the fresh-keeping drawer 300 back. At this time, the fresh-keeping drawer 300 moves horizontally backward, and the hard wire 37 fixed on the drawer body 31 will follow the drawer to run at the same speed. Since the drawer body 31 moves between the first permanent magnet 11 and the second permanent magnet 12, the hard wire 37 cuts the magnetic field induction line of the first magnetic field, generating an induced current in the closed loop. When the induced current flows in the closed loop, it drives the motor 13 to rotate, and then drives the indicator 39 to move. When the indicator 39 moves, it indicates that the food in the fresh-keeping drawer 300 is already in a fresh-keeping state.

[0082] In a specific embodiment, the power supply is controlled to provide a pulse current in a first direction to the first component, and the first component outputs a pulse magnetic field in a third direction; based on the pulse magnetic field in the third direction, an induced current in a first direction is generated; based on the induced current in the first direction, the motor 13 is controlled to rotate in a forward direction, and the indicator is driven to move along the first horizontal direction (for example, extend a certain distance).

[0083] In another specific embodiment, the power supply is controlled to provide a second-direction pulse current to the first component, and the first component outputs a fourth-direction pulse magnetic field; based on the fourth-direction pulse magnetic field, an induced current in the second direction is generated; based on the second-direction induced current, the motor 13 is controlled to rotate in the opposite direction, and the indicator is driven to move in the second horizontal direction (for example, retract to the initial position). The first direction is opposite to the second direction, the third direction is opposite to the fourth direction, and the first horizontal direction is opposite to the second horizontal direction.

[0084] In addition, the displacement generated after the indicator is actuated is related to the moving speed of the placement unit 14 in the second direction. Specifically, when the placement unit 14 moves along the second direction at a first speed and the indicator is actuated, the indicator generates a first displacement; when the placement unit 14 moves along the second direction at a second speed and the indicator is actuated, the indicator generates a second displacement; when the first moving speed is greater than the second moving speed, the first displacement is greater than the second displacement.

[0085] As shown in Figure 2(a), in one embodiment, the food preservation device 100 also includes an energy storage device 15, a first end of the energy storage device 15 is connected to a first end of the motor 13, and a second end of the energy storage device 15 is connected to a second end of the motor; when the storage unit 14 moves along the second direction, the energy storage device 15 is used to store the induced current and provide the induced current to the motor 13.

[0086] In this way, by introducing the energy storage component 15, the food preservation device 100 can effectively store the induced current when the storage unit 14 moves, and provide a stable current to the motor 13 when necessary to maintain a stable brightness.

[0087] Continuing with reference to FIG. 2( a ), in one embodiment, the food preservation device 100 further includes a voltage stabilizer 17 , wherein a first end of the voltage stabilizer 17 is connected to a first end of the motor 13 , and a second end of the voltage stabilizer 17 is connected to a second end of the motor 13 ; when the storage unit 14 moves along the second direction, the voltage stabilizer 17 is used to stabilize the power supply voltage supplied to the motor 13 .

[0088] In this way, by introducing the voltage stabilizing device 17 , it is ensured that no matter how the moving speed of the storage unit 14 changes, the driving motor 13 can be ensured to rotate stably.

[0089] Continuing with reference to FIG. 2( a ), in one embodiment, the food preservation device 100 further includes an energy storage device 15 and a voltage stabilizing device 17. The first end of the energy storage device 15 is connected to the first end of the motor 13, the second end of the energy storage device 15 is connected to the first end of the voltage stabilizing device 17, and the second end of the voltage stabilizing device 17 is connected to the second end of the motor 13.

[0090] 2( a ), in one embodiment, a groove 16 is provided on the storage unit 14 , and the motor 13 is disposed in the groove 16 .

[0091] In this way, the motor 13 is arranged in the groove 16 of the storage unit 14, which not only protects the motor 13 from external physical damage (such as collision, scratch, etc.), but also makes the entire device more beautiful and neat.

[0092] In summary, the present invention provides a food preservation device and refrigeration equipment. The food is preserved by a first magnetic field generated by a first component, and the indicator driven by a motor is moved to intuitively display the preservation status of the food. When the storage unit moves in a specific direction, if the indicator moves with it, it means that the food has been effectively preserved; if the indicator does not move, it means that the food has not been preserved. The device cleverly combines magnetic field preservation technology and mechanical indication principles, so that the indicator can move with the movement of the storage unit, thereby providing an intuitive and simple way to judge the preservation status.
