[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0031] The refrigerator products currently available on the market can only quickly cool down fruits and vegetables by letting in cold air. Air cooling will cause the water content of fruits and vegetables to decrease, affecting the quality of fruits and vegetables.

[0032] In order to reduce the occurrence of the above situation, that is, to increase the preservation time of fruits and vegetables and improve the preservation effect of fruits and vegetables, the embodiment of the present application provides a preservation device and a refrigerator, which will be described below with reference to the accompanying drawings.

[0033] See also Figure 1 As shown, Figure 1 This is a schematic diagram of the first structure of the preservation device provided in the embodiment of the present application. The embodiment of the present application provides a preservation device 100, which is mainly used to preserve and store fruits and vegetables to extend the preservation time of fruits and vegetables and meet the needs of users.

[0034] Exemplarily, the fresh-keeping device 100 includes a fresh-keeping container 110 , a humidifying component 120 and a refrigerating component 130 .

[0035] The fresh-keeping container 110 has a receiving space 111, which is used to receive fruit and vegetable food. Of course, the receiving space 111 can also receive other types of food. Since the embodiment of the present application is mainly aimed at the preservation and storage of fruit and vegetable food, the receiving space 111 is mainly used to receive fruit and vegetable food. Exemplarily, the fresh-keeping container 110 can be in the form of a drawer, so that the user can put in and take out the fruit and vegetable food.

[0036] At least a portion of the humidifying component 120 is located in the accommodating space 111 to humidify the fruit and vegetable food. It is understandable that the humidifying component 120 can be in the form of a spray, spraying toward the fruit and vegetable food so that water mist is generated on the surface of the fruit and vegetable food to keep it moist, thereby offsetting the problem of water shortage of the fruit and vegetable food caused by cold wind.

[0037] The refrigeration component 130 is used to blow cold air toward the accommodation space 111 and cool the water in the humidification component 120, so that the humidification component 120 generates water mist of a preset temperature to perform cold shock treatment on the fruit and vegetable food. The refrigeration component 130, such as a combination of components such as a compressor, a condenser, and an evaporator, can generate cold air to cool the fresh-keeping container 110 to refrigerate and preserve the fruit and vegetable food. The embodiment of the present application utilizes the cold air generated by the refrigeration component 130 to preserve the fruit and vegetable food at low temperature on the one hand, and on the other hand, it can also cool the water in the humidification component 120 to preserve the fruit and vegetable food using low-temperature water mist.

[0038] For example, when the user puts fruits and vegetables into the fresh-keeping container 110, the humidifying component 120 sprays low-temperature water of about 0°C on the surface of the fruits and vegetables in the form of mist to achieve the purpose of rapid cooling, thereby reducing the impact of the cold air generated by the refrigeration component 130 on the weightlessness of the fruits and vegetables.

[0039] Among them, it should be noted that temperature stimulation treatment is an emerging physical preservation method, and cold shock treatment is a type of temperature stimulation treatment, which can induce the physiological resistance of fruits and vegetables through cold stress and improve storage quality. Scientific and effective cold shock treatment can be well combined with the life characteristics of fruits and vegetables. It not only has a pre-cooling effect, but also can improve the cold resistance and disease resistance of fruits and vegetables. It has many advantages such as safety, high efficiency and environmental protection, simple operation, and significant preservation effect.

[0040] In the fresh-keeping device 100 provided in the embodiment of the present application, by low-temperature humidification of fruits and vegetables, cold shock treatment of fruits and vegetables can be achieved. The physiological resistance of fruits and vegetables themselves can be induced by cold stress, which not only has a pre-cooling effect, but also can improve the cold resistance and disease resistance of fruits and vegetables. Compared with the low-temperature storage in the prior art, it can not only ensure the moisture content on the surface of fruits and vegetables to extend the preservation time, but also improve the preservation effect of fruits and vegetables.

[0041] See also Figure 2 As shown, Figure 2A second structural schematic diagram of a fresh-keeping device provided in an embodiment of the present application. Exemplarily, the humidifying component 120 includes a water holding portion 121, a magnetizing portion 122, and a spraying portion 123. The water holding portion 121 is used to hold water, and the water holding portion 121 is located outside the fresh-keeping container 110 to avoid occupying the accommodation space 111 of the fresh-keeping container 110. The magnetizing portion 122 is disposed in the water holding portion 121 to magnetize water molecules. For example, magnetic powder can be coated on a plate surrounding the water holding portion 121, and the magnetic powder can act on the water in the water holding portion 121 to magnetize the water, and the magnetic field generated by the coating of the magnetic powder in the water holding portion 121 can keep the water at about 0°C without freezing. The spraying portion 123 is connected to the water holding portion 121 to spray the magnetized water molecules onto fruit and vegetable food. When the humidifying component 120 sprays water mist at a certain flow rate, the water molecules perpendicular to the direction of the magnetic flux lines can be magnetized, and the magnetized water molecules have a certain bactericidal effect. Therefore, on the one hand, the fruits and vegetables in the fresh-keeping container 110 are subjected to low-temperature humidification and cold shock treatment to increase the humidity and physiological resistance of the fruits and vegetables and extend their storage time; on the other hand, the low temperature of the refrigeration component 130 inhibits the production of some bacteria and extends their storage time; thirdly, magnetized water is used for sterilization, that is, there are at least three measures for the preservation of fruits and vegetables.

[0042] Of course, the preservation of fruit and vegetable food in the embodiment of the present application is not limited to the above-mentioned sterilization and cooling methods, and sterilization can also be performed through a magnetic field.

[0043] See also Figure 3 As shown, Figure 3 A third structural schematic diagram of the fresh-keeping device provided in an embodiment of the present application. Exemplarily, the fresh-keeping device 100 also includes a magnetic field component 140, which can radiate a magnetic field into the accommodation space 111, and sterilize fruit and vegetable foods by relying on the magnetic field strength. For example, the magnetic field component 140 includes at least one coil 141, and at least one coil 141 is disposed on the outer wall of the fresh-keeping container 110 to radiate a magnetic field into the accommodation space 111 when powered on. The number of coils 141 can be determined according to the magnetic field strength to be radiated, and the magnetic field strength can be changed by adjusting the current.

[0044] Among them, illustratively, the preservation device 100 has a pretreatment state and a continuous preservation state. In the pretreatment state, the magnetic field component 140 has a first magnetic field strength to pretreatment the fruit and vegetable food. In the continuous preservation state, the magnetic field component 140 has a second magnetic field strength to continuously preserve the fruit and vegetable food, and the second magnetic field strength is less than the first magnetic field strength. It can be understood that when the fruit and vegetable food is just put in, a higher current can be passed to generate a stronger magnetic field to quickly sterilize the bacteria carried by the fruit and vegetable food. When the pretreatment stage is over, the current and magnetic field strength can be reduced, which can not only stably and continuously sterilize the fruit and vegetable food, but also reduce energy consumption.

[0045] It should be noted that the low-temperature water mist generated by the humidifying component 120 can not only have an effect on fruits and vegetables, but also offset the heat generated by the coil 141 of the magnetic field component 140, thereby reducing the impact of the heat generated by the coil 141 on the preservation of fruits and vegetables.

[0046] See also Figure 4 As shown, Figure 4 A fourth structural schematic diagram of a fresh-keeping device provided in an embodiment of the present application. Exemplarily, the fresh-keeping device 100 also includes a temperature sensing component 150, which is disposed in the accommodating space 111 to detect the surface temperature of fruits and vegetables. For example, the temperature sensing component 150 may be an infrared temperature sensing component, and the working principle of infrared temperature measurement is to gather the infrared radiation energy of the target object within its field of view through a special optical system of the thermometer, and the infrared energy is focused on the photodetector and converted into a corresponding electrical signal, and then passes through an amplifier and a signal processing circuit, and is converted into the temperature value of the measured target after correction according to the algorithm in the instrument and the target emissivity.

[0047] Exemplarily, the fresh-keeping device 100 also includes a controller 160, which is electrically connected to the temperature sensing component 150 and the humidifying component 120, respectively, to control the water output and water output duration of the humidifying component 120 according to the temperature of the surface of the fruit and vegetable food detected by the temperature sensing component 150, or to adjust the water mist amount and spraying time of the humidifying component 120 according to the temperature of the surface of the fruit and vegetable food.

[0048] Exemplarily, when the user puts fruits and vegetables into the fresh-keeping container 110, the temperature sensing component 150 detects the surface temperature of the fruits and vegetables. For example, when the surface temperature of the fruits and vegetables is higher than 4°C, the humidifying component 120 can be turned on to humidify the fruits and vegetables, and the coil 141 in the magnetic field component 140 can be energized. The low-temperature water mist sprayed by the humidifying component 120 is perpendicular to the magnetic flux lines generated by the coil, and the water molecules are magnetized, which can achieve the purpose of precooling the fruits and vegetables, and the magnetized water can also achieve the purpose of sterilization. In addition, the strong magnetic field generated by the strong current of the coil 141 of the magnetic field component 140 can sterilize the fruits and vegetables, reducing the contamination of the fruits and vegetables and the entire fresh-keeping container 110 by microorganisms. When the temperature on the surface of the fruits and vegetables reaches the final suitable storage temperature, the humidifying component 120 is turned off, and the current of the coil 141 is reduced to store the fruits and vegetables at a lower magnetic field strength, thereby reducing unnecessary energy consumption.

[0049] In the preservation device 100 provided in the embodiment of the present application, by low-temperature humidification of fruits and vegetables, cold shock treatment of fruits and vegetables can be achieved. The physiological resistance of fruits and vegetables is induced by cold stress, which not only has a pre-cooling effect, but also can improve the cold resistance and disease resistance of fruits and vegetables. Compared with the low-temperature storage in the prior art, it can not only ensure the surface water content of fruits and vegetables to extend the preservation time, but also improve the preservation effect of fruits and vegetables. The low-temperature water spray humidification component 120 can quickly cool down the fruits and vegetables placed in the preservation container 110, reducing the impact of cold wind on the weightlessness of fruits and vegetables. The magnetized water molecules can achieve a bactericidal effect, reduce microbial contamination on the surface of fruits and vegetables, and inhibit corruption. The temperature sensing component 150 can accurately sense the temperature of the surface of fruits and vegetables and adjust it, reducing the impact of the user opening and closing the preservation container 110. The energized coil 141 can change the magnetic field strength by adjusting the current size, high magnetic field sterilization, low magnetic field antibacterial, keep the continuous movement of fruit and vegetable molecules, achieve the purpose of preservation, and avoid the reaction and energy consumption problems of long-term high magnetic field. The heat generated by the relatively strong current passing through the coil 141 can also offset the low-temperature water mist, thereby reducing the impact of the heat of the coil 141 on fruits and vegetables.

[0050] It should be noted that the fresh-keeping device 100 of the embodiment of the present application can be an independent device for preserving and storing fruits and vegetables, such as used in a large cold storage and fruit and vegetable storage room, or the fresh-keeping device 100 can be a part of a refrigerator.

[0051] Please combine Figures 1 to 4 Also see Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram of the first structure of the refrigerator provided in the embodiment of the present application. Figure 6 The second structural schematic diagram of the refrigerator provided by the embodiment of the present application. To this end, the embodiment of the present application also provides a refrigerator 1000, which includes a fresh-keeping device 100. The structural composition of the fresh-keeping device 100 is as described above and will not be repeated here. The refrigerator 1000 also includes a refrigerating compartment 200. The refrigerating compartment 200 can be provided with different interlayers. The fresh-keeping container 110 in the fresh-keeping device 100 can be arranged in the refrigerating compartment 200, such as a drawer and an interlayer of the refrigerating compartment 200. The water-containing part 121 of the humidifying component 120 in the fresh-keeping device 100 can be arranged in the box of the refrigerator 1000 to save the storage space occupied by the refrigerating compartment 200. Among them, the refrigerating component 130 in the fresh-keeping device 100 can be shared with the refrigerator 1000, that is, the fresh-keeping device 100 reuses the refrigerating device of the refrigerator 1000, which can reduce the setting of the device, save energy consumption and space arrangement difficulty.

[0052] In the fresh-keeping device 100 and refrigerator 1000 provided in the embodiment of the present application, by low-temperature humidification of fruits and vegetables, cold shock treatment of fruits and vegetables can be achieved. The physiological resistance of fruits and vegetables themselves can be induced by cold stress, which not only has a pre-cooling effect, but also can improve the cold resistance and disease resistance of fruits and vegetables. Compared with the low-temperature storage in the prior art, it can not only ensure the surface water content of fruits and vegetables to extend the preservation time, but also improve the preservation effect of fruits and vegetables. The low-temperature water spray humidification component 120 can quickly cool down the fruits and vegetables placed in the fresh-keeping container 110, reducing the impact of cold wind on the weightlessness of fruits and vegetables. The magnetized water molecules can achieve a bactericidal effect, reduce microbial contamination on the surface of fruits and vegetables, and inhibit corruption. The temperature sensing component 150 can accurately sense the temperature of the surface of fruits and vegetables and adjust it, reducing the impact of users opening and closing the fresh-keeping container 110. The energized coil 141 can change the magnetic field strength by adjusting the current, with high magnetic field sterilizing and low magnetic field inhibiting bacteria, thus maintaining the continuous movement of fruit and vegetable molecules to achieve the purpose of preservation and avoid the adverse effects and energy consumption problems of long-term high magnetic field. The heat generated by the strong current passing through the coil 141 can also offset each other with the low-temperature water mist, reducing the impact of the heat of the coil 141 on fruit and vegetable food.
