[0024] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The utility model provides a high-frequency electric field transmitting system, such as Figure 1 and Figure 2As shown, the high-frequency electric field transmitting system includes a high-frequency electric field generating device 1 and a wire 2; the high-frequency electric field generating device 1 is used to generate a high-frequency electric field, one end of the wire 2 is connected to the output end of the high-frequency electric field generating device 1, and the other end is idle, and the wire 2 is used to be arranged around the periphery of the storage chamber 3, and the resistance of the wire 2 increases with the increase of the electromagnetic frequency. When the electromagnetic reaches a certain frequency, it can become an effective load and emit an electromagnetic field, so that the wire 2 is used as a transmitting device to release the high-frequency electric field to the storage chamber 3, so as to achieve food preservation through the high-frequency electromagnetic field.

[0026] In a high-frequency electromagnetic field, the frequency and intensity will change dramatically, producing a violent oscillation effect, which can relax the chemical bonds between ions and proteins, change the microstructure of oxidase, make it inactive, reduce the probability of enzyme-catalyzed reactions, and slow down food oxidation and aging; at the same time, water molecules are polar molecules, and high-frequency electromagnetic fields constantly change the direction of the magnetic field, which can cause water molecules to vibrate to prevent ice crystal nucleation, thereby maintaining a supercooled state and forming rounder, smaller ice crystals, which is beneficial to protecting the integrity of cell membranes and improving the quality of frozen preservation, and is especially suitable for the long-term storage of meat and seafood.

[0027] Furthermore, the conductor 2 is cheaper than the electrode plate, thereby greatly reducing the production cost while achieving freshness preservation.

[0028] It is understandable that the storage chamber 3 has a cover that can be opened and closed, and has a storage space of a certain volume. The output voltage of the high-frequency electric field generating device 1 is 2KV to 3KV, which is a relatively high voltage. When the wire 2 receives the output of the high-frequency electric field generating device 1 and transmits it to the storage chamber 3, since only one end of the wire 2 is connected to the high-frequency electric field generating device 1 and the other end is vacant, and both ends of the wire 2 are not connected to the high-frequency electric field generating device 1, no adverse consequences such as breakdown will occur, thereby ensuring the normal use of the high-frequency electric field transmitting system.

[0029] The wire 2 may be a metal strip, a bare wire, an electromagnetic wire or an insulated wire; the wire 2 may be arranged in a variety of different ways around the storage chamber 3:

[0030] In one embodiment of the present application, Figure 3 As shown, the wire 2 is spirally wound and arranged on the periphery of the storage chamber 3. Specifically, one end of the wire 2 is connected to the output end of the high-frequency electric field generating device 1, and the wire 2 is spirally wound from one end of the storage chamber 3 to the other end; the end of the wire 2 not connected to the high-frequency electric field generating device 1 is left empty.

[0031] In one implementation of this embodiment, the conductive wire 2 is wound into a single turn or multiple turns.

[0032] Specifically, the number of turns of the wire 2 wound outside the storage chamber 3 can be determined according to the actual required magnetic field strength. The more turns the wire 2 is wound, the smaller the distance between the two parallel lines, the denser the distribution of the wire 2 outside the storage chamber 3, the stronger the current passing through the wire 2, and the stronger the magnetic field formed by the wire 2. Therefore, when the storage chamber 3 is small in size, the food is small, and the required electromagnetic field strength is low, the wire 2 can be wound in a single turn; when the storage chamber 3 is large in size, the food is large, and the required electromagnetic field strength is high, the wire 2 can be wound in multiple turns.

[0033] It should be noted that when the wire 2 is arranged in a spiral winding manner, the wire 2 can be only one or multiple (multiple wires 2 are wound in sequence). When the wire 2 is wound into multiple turns, the distance between two adjacent parallel lines is 10 cm to 50 cm to ensure the effectiveness of the field strength.

[0034] In another embodiment of the present application, there are multiple wires 2, and each of the wires 2 is arranged straight, and the multiple wires 2 are arranged in parallel in sequence and enclose a storage space; the storage chamber 3 is located in the storage space.

[0035] Specifically, any two adjacent wires 2 are parallel to each other, and a plurality of the wires 2 are erected around the storage chamber 3, thereby enclosing and forming a accommodating space to accommodate the storage chamber 3, and applying an electromagnetic field to the storage chamber 3 to achieve freshness preservation.

[0036] In one implementation of this embodiment, the distance between two adjacent wires is less than 1 m to ensure the effectiveness of the field strength.

[0037] In one embodiment of the present application, the output frequency of the high-frequency electric field generating device 1 is 10kHZ~1Mhz, and the spatial electric field strength is maintained above 30v / m, which can reduce the damage to frozen meat tissue and reduce the production of blood; it can also inhibit the activity of enzymes and increase the preservation effect of refrigerated foods.

[0038] In one embodiment of the present application, the high-frequency electric field generating device 1 includes a voltage-smoothing and rectifying device 11, a frequency converter 12 and a protection device 13; the input end of the voltage-smoothing and rectifying device 11 is connected to an external power supply and is used to boost the voltage output by the power supply; the input end of the frequency converter 12 is connected to the output end of the voltage-smoothing and rectifying device 11, the output end of the frequency converter 12 is connected to one end of the wire 2, and is used to boost the frequency output by the voltage-smoothing and rectifying device 11; the output end of the frequency converter 12 is also connected to the protection device 13.

[0039] Specifically, the voltage rectifying device 11 is used to boost the output voltage of the power supply. In this embodiment, the voltage value of the DC power supply is 12V and the frequency is 50Hz. The voltage rectifying device 11 boosts the voltage to about 3KV; the frequency converter 12 adjusts the frequency to a specific high frequency (such as 10kHZ-1Mhz), and then releases it through the wire 2. The protection device 13 is grounded and realizes protection against overvoltage and overcurrent phenomena in the circuit.

[0040] In one implementation of the present embodiment, the voltage-regulating and rectifying device 11 includes a full-wave rectifying module, which can be realized by a metal oxide semiconductor field effect transistor; the inverter 12 is a two-level direct high-voltage inverter with power devices connected in series, or a three-level voltage source inverter, or a unit-connected multi-level voltage source inverter.

[0041] Among them, the three-level voltage source inverter can adopt IGCT (integrated gate commutated thyristor) and HV-IGBT (high voltage insulated gate bipolar transistor) three-level voltage source inverter; the unit series multi-level voltage source inverter can adopt LV-IGBT (low voltage insulated gate bipolar transistor) unit series multi-level voltage source inverter.

[0042] The present application also provides a refrigeration mechanism, such as Figure 2 As shown, it includes the high-frequency electric field transmitting system as described in any one of the above items, and also includes a storage chamber 3; the wire 2 is arranged around the periphery of the storage chamber 3 to release a high-frequency electromagnetic field to the storage chamber 3.

[0043] It is understandable that the refrigeration mechanism can be a refrigerator, a freezer, etc., which is used for refrigerating and preserving food to improve the preservation effect, and can also be used in other electric field application fields, such as medical, cooking and other industries. When the refrigeration mechanism is a refrigerator, the storage chamber 3 includes a refrigerating chamber and a freezing chamber, and the conductors 2 are arranged on the periphery of the refrigerating chamber and the freezing chamber, so as to release a high-frequency electromagnetic field to the refrigerating chamber and the freezing chamber, thereby reducing production costs and improving the preservation effect.

[0044] In summary, the present application also provides a high-frequency electric field emission system and a refrigeration mechanism, wherein the high-frequency electric field emission system includes a high-frequency electric field generating device and a wire; the high-frequency electric field generating device is used to generate a high-frequency electric field, one end of the wire is connected to the output end of the high-frequency electric field generating device, and the other end is idle, and the wire is used to be arranged around the periphery of the storage chamber, and the resistance of the wire increases with the increase of the electromagnetic frequency. When the electromagnetic reaches a certain frequency, it can become an effective load and emit an electromagnetic field, so that the wire is used as a transmitting device to release the high-frequency electric field to the storage chamber, thereby realizing food preservation through a high-frequency electromagnetic field; and the wire is cheaper than the electrode plate, thereby greatly reducing the production cost while achieving freshness preservation.

For ordinary technicians in this field, improvements or changes can be made according to the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
