Description

Technical Field

[0001] The present invention relates to the field of household appliances, and particularly to a food preservation device and a refrigeration equipment. Background Art

[0002] In the existing field of food preservation technology, traditional preservation methods such as refrigeration and vacuum packaging can, to a certain extent, extend the storage time of food, but often have problems such as high energy consumption, limited preservation effect, and inconvenient operation. In particular, these methods often cannot provide real-time feedback on the preservation status, making it difficult for users to intuitively understand the current degree of food preservation, which may lead to missing the best consumption time or causing food waste.

[0003] In recent years, with the development of technology, some new food preservation devices have started to adopt magnetic field preservation technology, treating food through a specific magnetic field to achieve the purpose of slowing down spoilage and extending the preservation period. However, there are still some deficiencies in the design and use of these devices. For example, some devices fail to effectively combine the usage habits and needs of users, lacking an intuitive preservation status indication, making it impossible for users to accurately judge the preservation status of food during use. In addition, some devices lack flexibility in the selection and regulation of the magnetic field intensity, resulting in unstable preservation effects and even potentially causing unnecessary damage to food. Summary of the Invention

[0004] One of the purposes of the present invention is to provide a food preservation device to solve the technical problem in the prior art that there is a lack of a technology for economically and efficiently detecting the preservation function in a food preservation device.

[0008] As a further improvement of an embodiment of the present invention, the first permanent magnet is disposed above the second permanent magnet, and the distance between the storage unit and the first permanent magnet is equal to the distance between the storage unit and the second permanent magnet.

[0009] As a further improvement of an embodiment of the present invention, when the storage unit moves in the second direction at a first speed and the first indicator light is on, the first indicator light is at a first brightness; when the storage unit moves in the second direction at a second speed and the first indicator light is on, the first indicator light is at a second brightness; when the first moving speed is greater than the second moving speed, the first brightness is higher than the second brightness.

[0010] As a further improvement of an embodiment of the present invention, the food freshness preservation device further includes an energy storage device. The first end of the energy storage device is connected to the first end of the first indicator light, and the second end of the energy storage device is connected to the second end of the first indicator light; when the storage unit moves in the second direction, the energy storage device is used to store the induced current and provide the induced current to the first indicator light.

[0013] As a further improvement of an embodiment of the present invention, the included angle between the second direction and the first direction is 90°.

[0015] Compared with the prior art, the embodiments of the present invention have at least one of the following beneficial effects:

[0016] The present invention discloses a food preservation device. By utilizing the magnetic field component of the first magnetic field generated by the first component along the first direction, food is preserved. When the storage unit moves, the first indicator light will turn on, indicating that the food has been effectively preserved. Conversely, if the indicator light goes out, it may indicate that the storage unit is not in the optimal preservation position, or the food has not been fully preserved.

[0030] As Figure 1 shown, an embodiment of the present invention provides a refrigeration device 200.

[0031] The refrigeration device 200 may include a refrigeration compartment, and a food preservation device is provided in the refrigeration compartment.

[0032] In one embodiment, the food preservation device can be arranged as described hereinafter.

[0033] The refrigeration device 200 may specifically be a computer device, and the computer device may be a terminal device or a server.

[0034] The refrigeration device 200 includes at least one processor. Specifically, the processor may be a Central Processing Unit (CPU) 21.

[0035] 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.

The central processor 21, the read-only memory 22, and the random access memory 23 are connected to each other via a bus 24.

[0038] An embodiment of the present invention provides a food preservation device 100.

[0039] The food preservation device 100 refers to a device or container specifically used for storing, preserving, and managing food ingredients. These devices can ensure that the food ingredients remain fresh, nutritious, and have a good taste during storage. The food preservation device 100 may be a refrigerator, a cold storage cabinet, or a certain module in a refrigerator or a cold storage cabinet, such as a preservation drawer, etc.

[0040] As shown in Fig. 2(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 marks whether the food at the storage unit 14 is in an effective preservation state by affecting the first indicator light 13.

[0041] It should be noted that the preservation of food by the magnetic field is mainly reflected in that the magnetic field can inhibit the growth of microorganisms and molds, thereby extending the storage period of the food. Specifically, when using the magnetic field to assist in storing food, the magnetic field restricts the free path of water molecules to a certain extent. Specifically, the hydrogen bonds in the water molecule group are broken, so that during the phase change of water, the growth of crystal nuclei is inhibited, the growth rate of ice crystals is higher than the migration rate of water molecules, and the generated ice crystals are smaller, thus causing less damage to cells and reducing the juice loss rate of the food, so that the nutrition and taste of the food can be better preserved. Therefore, the magnetic field can be used to assist in storing food, thereby achieving the purpose of extending the storage period of the food.

[0042] In one embodiment, the first component includes a first permanent magnet 11 and a second permanent magnet 12, and the storage unit 14 is disposed between the first permanent magnet 11 and the second permanent magnet 12.

[0043] In this embodiment, the first magnetic field is jointly 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 generated first magnetic field is not easily affected by external interference and can be regarded as relatively constant. Therefore, 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.

[0044] In a specific embodiment, as shown in Figs. 3(a) and 3(b), the poles of the end of the first permanent magnet 11 close to the storage unit 14 and the end of the second permanent magnet 12 close to the storage unit 14 are opposite.

[0045] In this way, a closed magnetic circuit can be formed, the magnetic field intensity at the storage unit 14 can be enhanced, and the preservation efficiency can be improved. In addition, the opposite poles can also prevent the formation of a region with a 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.

[0046] 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. 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 lines and causing a change in the magnetic flux of the closed loop formed by the first indicator light 13, thus generating an induced current in the closed loop.

[0047] In a specific embodiment, the first permanent magnet 11 is disposed above the second permanent magnet 12, as Figure 3(a) and 3(b) shown. The distance between the storage unit 14 and the first permanent magnet 11 is equal to the distance between the storage unit 14 and the second permanent magnet 12.

[0048] In this way, this up-and-down symmetric layout helps to form a uniform and stable magnetic field environment at the storage unit 14. The equal-distance setting ensures the consistency of the magnetic field action on each part of the food ingredients, avoiding the difference in the preservation effect caused by uneven magnetic field distribution.

[0049] In other embodiments, the first permanent magnet 11 and the second permanent magnet 12 can also be disposed on the left and right sides of the storage unit 14, as Figure 4(a) and 4(b) shown. The distance between the storage unit 14 and the first permanent magnet 11 is equal to the distance between the storage unit 14 and the second permanent magnet 12.

[0050] 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 is closer to the first permanent magnet 11. The present invention does not make specific restrictions on this.

[0051] In other embodiments, the first component can also be other types of magnets or electromagnetic coils, and a first magnetic field is generated by energizing the first component. The present invention does not make specific restrictions on this.

[0052] It should be noted that when the storage unit 14 moves (pushed back or pulled out) along the second direction, its position relative to the first permanent magnet 11 and the second permanent magnet 12 changes, which causes a change in the magnetic flux passing through the closed loop in the storage unit 14. The increase or decrease of the magnetic flux can be determined based on the movement direction of the storage unit 14 and the polarity configuration between the first permanent magnet 11 and the second permanent magnet 12.

[0053] Specifically, when the storage unit 14 performs a moving operation in the first magnetic field, due to the continuous change of magnetic flux (for example, first increasing and then decreasing, or first decreasing and then increasing), the direction of the induced current generated in the closed loop will also change accordingly. This change depends on the movement trajectory and speed of the storage unit 14, as well as the polarity configuration and intensity of the first permanent magnet 11 and the second permanent magnet 12.

[0054] In a specific embodiment, the end of the first permanent magnet 11 close to the storage unit 14 is configured as the south pole, and the end of the second permanent magnet 12 close to the storage unit 14 is configured as the north pole.

[0055] In this embodiment, the south pole of the first permanent magnet 11 is close to the storage unit 14, while the north pole of the second permanent magnet 12 is close to the storage unit 14. This means that between the first permanent magnet 11 and the second permanent magnet 12, the magnetic field lines of the first magnetic field will start from the north pole of the second permanent magnet 12 and point to the south pole of the first permanent magnet 11. The storage unit 14 will be located in this first magnetic field.

[0056] In another specific embodiment, the end of the first permanent magnet 11 close to the storage unit 14 is configured as the north pole, and the end of the second permanent magnet 12 close to the storage unit 14 is configured as the south pole.

[0057] In this embodiment, the north pole of the first permanent magnet 11 is close to the storage unit 14, while the south pole of the second permanent magnet 12 is close to the storage unit 14. Therefore, between the first permanent magnet 11 and the second permanent magnet 12, the magnetic field lines will start from the north pole of the first permanent magnet 11 and point to the south pole of the second permanent magnet 12. The storage unit 14 will be located in this first magnetic field.

[0058] The magnetic field directions of the first magnetic fields generated in the above two embodiments are different, and when the storage unit 14 moves along the second direction, the directions of the induced currents generated in the closed loop are also different.

[0059] The food preservation device 100 includes a storage unit 14 for placing food. For example, the storage unit 14 is a fresh-keeping box.

[0060] In one embodiment, the first magnetic field includes a magnetic field component along the 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.

[0061] The second direction forms an angle with the first direction, which means that the storage unit does not move along the direction of the magnetic induction lines of the first magnetic field, but cuts the magnetic induction lines at an angle.

[0062] In a specific embodiment, the second direction forms an angle of 90° with the first direction.

[0063] In this way, moving the storage unit along the second direction which is at a 90° angle to the first direction can maximize the use of space while ensuring that the hard wire generates the maximum induced current when cutting the magnetic induction line. This design not only improves the efficiency of energy conversion but also makes the structure of the entire device more compact and reasonable.

[0064] The food preservation device 100 includes a first indicator light 13, and the first indicator light 13 is fixed at the storage unit 14. The first end of the first indicator light 13 is coupled to its second end to form a closed loop for inducing a first magnetic field and generating an induced current.

[0065] In this embodiment, "coupled" does not mean that the entire closed loop is completely composed of the electrical components inside the first indicator light 13. In fact, "coupled" here means that one electrical connection point of the first indicator light 13 is connected to another electrical connection point through an external wire or other electrical connection components, thereby forming a closed path through which current can flow.

[0066] In one embodiment, the food preservation device 100 may further include at least one of a hard wire and a circuit module.

[0067] Among them, the hard wire is used to establish a stable current transmission path inside or outside the food preservation device 100, can effectively transmit current, and has the characteristic of stable structure. The circuit module is used to process input signals, perform logical operations, and output control signals to drive other components.

[0068] In a specific embodiment, the first end of the first indicator light 13 is connected to the first end of the hard wire, and the second end of the first indicator light 13 is connected to the second end of the hard wire. In this embodiment, the closed loop is formed by the mutual connection of the first indicator light 13 and the hard wire.

[0069] In another specific embodiment, the first end of the first indicator light 13 is connected to the first end of the circuit module, and the second end of the first indicator light 13 is connected to the second end of the circuit module. In this embodiment, the closed loop is formed by the mutual connection of the first indicator light 13 and the circuit module.

[0070] In still another specific embodiment, the first end of the first indicator light 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 first indicator light 13. In this embodiment, the closed loop is formed by the pairwise mutual connection of the first indicator light 13, the hard wire, and the circuit module.

[0071] In this embodiment, the circuit module, the first indicator light 13, and the rigid wire can be installed at the body of the storage unit 14. For example, as Figure 5 shown, taking the fresh-keeping drawer as an example for the storage unit 14, the fresh-keeping drawer 300 includes a drawer body 31 for placing food ingredients; a drawer decorative piece 32 disposed around the drawer body 31 for providing additional functions (for example, for fixing the first indicator light); a drawer front cover 34 disposed at the front end of the drawer body 31 for opening or closing the drawer; and a drawer frame 33 fixed around the drawer body 31 for protecting the internal structure of the drawer.

[0072] In this embodiment, the drawer front cover 34, the drawer frame 33, and the drawer decorative piece 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 certain fixed position above; 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 certain fixed position below.

[0073] Continuing to refer to Figure 5 shown, the rigid wire 37 is arranged around the perimeter of the drawer body 31. The first end of the rigid wire 37 is connected to the first end of the circuit module 36, and the second end of the rigid wire 37 is connected to the second end of the circuit module 36 to form a closed loop. The first indicator light 13 is arranged on the circuit module 36.

[0074] In 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 can be seen in FIGS. 3(a) and 3(b). The magnetic induction lines will be perpendicular to the moving direction of the drawer, pointing from the north pole (N pole) of the magnet to the south pole (S pole). When the fresh-keeping drawer is pulled out or pushed in horizontally, it will cut these magnetic induction lines perpendicular to the moving direction, generating an induced current.

[0075] Of course, the first permanent magnet 11 and the second permanent magnet 12 can also be respectively 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; the second permanent magnet 12 is arranged on the other side of the fresh-keeping drawer, that is, the right side, as can be seen in FIGS. 4(a) and 4(b).

[0076] In 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 induction lines will be parallel to the side of the fresh-keeping drawer, pointing from the north pole (N pole) of the magnet to the south pole (S pole). The moving direction of the fresh-keeping drawer needs to form a certain angle with the direction of the magnetic induction lines to cut these magnetic induction lines to form an induced current.

[0077] A groove 16 is provided at the drawer decoration, and the first indicator light 13 is fixed in the groove 16.

[0078] In one embodiment, when the storage unit 14 moves in the second direction and the first indicator light 13 is off, the food materials at the storage unit 14 are not fresh-preserved.

[0079] In one embodiment, when the storage unit 14 moves in the second direction and the first indicator light 13 is on, the food materials at the storage unit 14 have been fresh-preserved.

[0080] To facilitate understanding of the process of the first indicator light 13 being off or on, continue to refer to FIGS. 2(a), 2(b) and Figure 5 As shown, for example, taking the fresh-keeping drawer 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, a first magnetic field exists in the fresh-keeping drawer; a closed loop formed by the first indicator light 13 and the rigid wire 37 is arranged on the drawer body 31 of the fresh-keeping drawer.

[0081] When the user uses the fresh-keeping drawer 300, the fresh-keeping drawer 300 is pulled out, and the rigid wire 37 fixed on the drawer body 31 runs at the same speed as the drawer. Since the drawer body 31 moves between the first permanent magnet 11 and the second permanent magnet 12, the rigid wire 37 cuts the magnetic induction lines of the first magnetic field, and an induced current is generated in the closed loop. When the induced current flows in the closed loop, it will flow into the first indicator light 13, and the first indicator light 13 lights up. At this time, it indicates that the food materials in the fresh-keeping drawer 300 have been in a fresh-preserved state.

[0082] When the user finishes using the fresh-keeping drawer 300 and pushes the fresh-keeping drawer 300 back, at this time, the fresh-keeping drawer 300 moves horizontally backward, and the rigid wire 37 fixed on the drawer body 31 will run at the same speed as the drawer body 31. Since the drawer body 31 moves between the two permanent magnets, the rigid wire 37 cuts the magnetic induction lines of the first magnetic field, and an induced current is generated in the closed loop. When the induced current flows in the closed loop, it will flow into the first indicator light 13, and the first indicator light 13 lights up. At this time, it indicates that the food materials in the fresh-keeping drawer 300 have been in a fresh-preserved state.

[0083] In addition, the brightness of the first indicator light 13 is related to the moving speed of the storage unit 14 in the second direction. Specifically, when the storage unit 14 moves in the second direction at a first speed and the first indicator light 13 is on, the first indicator light 13 is at a first brightness; when the storage unit 14 moves in the second direction at a second speed and the first indicator light 13 is on, the first indicator light 13 is at a second brightness; when the first moving speed is greater than the second moving speed, the first brightness is higher than the second brightness.

[0084] As shown in Fig. 2(b), in one embodiment, the food preservation device 100 further includes an energy storage device 15. The first end of the energy storage device 15 is connected to the first end of the first indicator light 13, and the second end of the energy storage device 15 is connected to the second end of the first indicator light 13; when the storage unit 14 moves in the second direction, the energy storage device 15 is configured to store the induced current and supply the induced current to the first indicator light 13.

[0085] In this way, by introducing the energy storage device 15, the food preservation device 100 can effectively store the induced current when the storage unit 14 moves, and supply a stable current to the first indicator light 13 when needed to keep it at a stable brightness.

[0086] Continuing to refer to Fig. 2(b), in one embodiment, the food preservation device 100 further includes a voltage regulator 17. The first end of the voltage regulator 17 is connected to the first end of the first indicator light 13, and the second end of the voltage regulator 17 is connected to the second end of the first indicator light 13; when the storage unit 14 moves in the second direction, the voltage regulator 17 is configured to stabilize the power supply voltage supplied to the first indicator light 13.

[0087] In this way, by introducing the voltage regulator 17, it is ensured that the first indicator light 13 emits light with a constant brightness regardless of how the moving speed of the storage unit 14 changes.

[0088] Continuing to refer to Fig. 2(b), in one embodiment, the food preservation device 100 further includes an energy storage device 15 and a voltage regulator 17. The first end of the energy storage device 15 is connected to the first end of the first indicator light 13, the second end of the energy storage device 15 is connected to the first end of the voltage regulator 17, and the second end of the voltage regulator 17 is connected to the second end of the first indicator light 13.

[0089] Continuing to refer to Fig. 2(b), in one embodiment, a groove 16 is provided on the storage unit 14, and the first indicator light 13 is disposed in the groove 16.

[0090] In this way, the first indicator light 13 is arranged in the groove 16 of the storage unit 14, which not only protects the first indicator light 13 from external physical damage (such as collision, scratching, etc.), but also makes the whole device more beautiful and tidy.

[0091] In summary, the present invention provides a food preservation device and a refrigeration device. By utilizing the first magnetic field generated by the first component having a magnetic field component along the first direction, food is preserved. When the storage unit moves, the first indicator light will light up, indicating that the food has been effectively preserved. On the contrary, if the indicator light is off, it may indicate that the storage unit is not in the optimal preservation position, or the food has not been fully preserved. This method can not only use the magnetic field to achieve efficient food preservation, but also intuitively understand the preservation state of the food through the on-off state of the first indicator light, without opening the device or performing complex detections. This design improves the convenience of use and the user experience.
