The first fresh keeping container 11 or the second fresh keeping container 21 may be transparent or opaque. When the color of the first preservation container 11 or the second preservation container 21 is transparent, the user can see the types of the objects in the first preservation container 11 or the second preservation container 21 through the first preservation container 11 or the second preservation container 21, and further the waste of energy caused by frequently opening or closing the first preservation container 11 or the second preservation container 21 is avoided; when the color of the first fresh keeping container 11 or the second fresh keeping container 21 is opaque, the privacy of the user can be effectively protected. The first fresh-keeping container 11 or the second fresh-keeping container 21 may be made of plastic, rubber, or ceramic, such as ABS (Acrylonitrile Butadiene Styrene), PS (Polystyrene ), or purple sand.
The number of the first sensor 12 or the second sensor 22 may be plural, and when the first fresh food container 11 or the second fresh food container 21 is a drawer type, the first sensor 12 or the second sensor 22 may be disposed on the top and the side wall of the first fresh food container 11 or the second fresh food container 21, and optionally, may be disposed on the rear side wall.
The first sensor 12 may be a biosensor, which can detect microorganisms and toxins existing on an object, detect freshness of the object, and detect pesticide residues on the object. Optionally, the biosensor detects the presence of microorganisms and toxins on the object. For example, when a user places an object into the first cavity 111, the first sensor 12 identifies the microorganisms and toxins present on the object and generates microorganism data, which is then transmitted to the processor 30.
The sterilization device 13 may be an ultraviolet sterilization device, a plasma device, or an ozone sterilization device 13. The ultraviolet ray disinfection device can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in cells of a microorganism organism by using ultraviolet rays with proper wavelength, so that growth cell death and/or regeneration cell death are/is caused, and the effects of sterilization and disinfection are achieved. Under the action of an external electric field, a large amount of energetic electrons generated by medium discharge bombard microbial molecules, so that the microbial molecules are ionized, dissociated and excited, and then a series of complex physical and chemical reactions are initiated, so that the complex microbial molecules are converted into simple small-molecule safe substances, or toxic and harmful substances are converted into non-toxic and harmless or low-toxicity and low-harm substances. For example, when a user places an object into the first cavity 111, the first sensor 12 identifies the microorganisms and toxins present on the object and generates microorganism data, which is then transmitted to the processor 30. After the processor 30 obtains the microorganism data, the sterilization device 13 is controlled to operate according to the microorganism data, i.e. to sterilize the surface of the object.
The second sensor 22 may be a biosensor, which can detect microorganisms and toxins present on the object, detect freshness of the object, and detect pesticide residues on the object. Optionally, the biosensor detects the presence of microorganisms and toxins on the object. For example, when the user places an object into the second receiving chamber 211, the second sensor 22 recognizes microorganisms and toxins present on the object and generates data, and transmits the data to the processor 30.
Wherein, the magnetic field generated by the first magnetic field generating device 23 has the functions of sterilization and oxidation resistance. The sterilization effect means that the magnetic field can change the metabolism mechanism of microorganisms, reduce the relative expression level of bacteria, mold and mycotoxin synthetic gene segments, and effectively inhibit the generation of microbial toxins, thereby achieving the aim of fresh keeping; the antioxidant effect means that the magnetic field can improve the activity of some antioxidant enzymes such as catalase and superoxide dismutase, eliminate hydrogen peroxide and superoxide radical in the food material, and protect the histocyte of the food material from oxidative damage, such as fat oxidation. In addition, the magnetic field generated by the first magnetic field generator 23 can prevent the object from generating large ice crystals during the freezing process, and specifically, the large ice crystals can damage cell walls to cause cytoplasm outflow, thereby causing the reduction of the food quality. When the object is frozen, the freezing speed is gradually reduced from the surface to the center, and the quality of the object is easily reduced due to uneven distribution of the freezing speed. After long-time freezing, large ice crystals can damage tissue structures, cells cannot restore to the original state after unfreezing, cell sap is greatly lost, and the flavor and the quality of objects are influenced. For example, when the user places an object into the second cavity 211, the second sensor 22 recognizes microorganisms and toxins present on the object and generates microorganism data, which is then transmitted to the processor 30. After the processor 30 acquires the microbial data, the intensity of the magnetic field generated by the first magnetic field generating device 23 is controlled to be greater than the preset magnetic field intensity according to the microbial data, so that the object is sterilized and resistant to oxidation, and large ice crystals are prevented from existing in the frozen object.

By the above, to the object that fresh-keeping demand is different, not only can provide the temperature of adaptation and preserve, can also use different fresh-keeping means to keep fresh to the object to can realize eating the continuation of material fresh-keeping.
In some embodiments, please refer to fig. 6, fig. 6 is a second structural schematic diagram of the first fresh keeping container and the interior thereof according to the embodiment of the present disclosure. The refrigerator 100 further includes a third sensor 14, the third sensor 14 is disposed in the first accommodating cavity 111, the third sensor 14 is used for identifying an object in the first accommodating cavity 111, the processor 30 is connected to the third sensor 14, and if the third sensor 14 identifies that an object is stored in the first accommodating cavity 111, the sterilizing device 13 is controlled to sterilize the object. If the third sensor 14 recognizes that the first receiving chamber 111 does not contain any object, the processor 30 controls the second sensor 22 and the sterilization device 13 to be disabled.
The third sensor 14 may be an infrared sensor and an image sensor, and the infrared sensor may detect whether or not an object is stored in the first accommodating chamber 111 by using the properties of infrared ray such as reflection, refraction, scattering, interference, and absorption; the image sensor can shoot the object in the first accommodating cavity 111, and can detect whether the object is stored in the first accommodating cavity 111 or not when the shot image and video are detected.
For example, when a user puts an object into the first accommodating cavity 111, the third sensor 14 identifies the object in the first accommodating cavity 111, and then recognizes that the object is stored in the first accommodating cavity 111 and transmits information that the object is stored in the first accommodating cavity 111 to the processor 30, and after the processor 30 receives the information that the object is stored in the first accommodating cavity 111, the first sensor 12 identifies microorganisms and toxins present on the object and generates microorganism data, and then transmits the microorganism data to the processor 30. After the processor 30 obtains the microorganism data, the sterilization device 13 is controlled to operate according to the microorganism data, i.e. to sterilize the surface of the object. When the user takes out the object from the first accommodating cavity 111, the third sensor 14 recognizes the object in the first accommodating cavity 111, recognizes that no object is stored in the first accommodating cavity 111, transmits information that no object is stored in the first accommodating cavity 111 to the processor 30, and the processor 30 receives the information that no object is stored in the first accommodating cavity 111 and controls the first sensor 12 and the sterilizing device 13 to stop operating.
When the third sensor 14 recognizes that an object is stored in the first receiving chamber 111, the sterilization device 13 is controlled to sterilize the object. For example, if the third sensor 14 recognizes that an object is stored in the first accommodating cavity 111, the processor 30 controls the first sensor 12 to obtain the microorganism concentration in the first accommodating cavity 111, and if the microorganism concentration in the first accommodating cavity 111 is greater than or equal to a first preset value, controls the degerming device 13 to degerming the object. It will be appreciated that the initial moment when the third sensor 14 recognizes that an object is present in the first receiving chamber 111 defines the moment when the degerming device 13 is activated. For example, at the initial time, the sterilizing device 13 has an on/off ratio of 0 to 30%, and the current flowing through the sterilizing device 13 is 0 to 0.3A.
It can be understood that the third sensor 14 can determine whether an object exists in the first accommodating cavity 111 and then confirm whether the first sensor 12 and the degerming device 13 are working, so that the first sensor 12 and the degerming device 13 can be dynamically turned on or off, the overload in the refrigerator 100 can be avoided, and energy can be effectively saved.
In some embodiments, please refer to fig. 7, and fig. 7 is a third structural diagram of the first fresh keeping container and the interior thereof according to the embodiment of the present disclosure.

And if the concentration of the microorganisms in the first accommodating cavity 111 is less than a second preset value, controlling the second magnetic field generating device 15 to stop working.
Wherein the magnetic field generated by the second magnetic field generating device 15 has the functions of sterilization and oxidation resistance. The sterilization effect means that the magnetic field can change the metabolism mechanism of microorganisms, reduce the relative expression level of bacteria, mold and mycotoxin synthetic gene segments, and effectively inhibit the generation of microbial toxins, thereby achieving the aim of fresh keeping; the antioxidant effect means that the magnetic field can improve the activity of some antioxidant enzymes such as catalase and superoxide dismutase, eliminate hydrogen peroxide and superoxide radical in the food material, and protect the histocyte of the food material from oxidative damage, such as fat oxidation. For example, when a user places an object into the first cavity 111, the first sensor 12 identifies the microorganisms and toxins present on the object and generates microorganism data, which is then transmitted to the processor 30. After the processor 30 has acquired the microbial data, it is determined by comparison whether the first magnetic field generating device 23 and the sterilizing device 13 are operating. If the concentration of the microorganisms in the first accommodating cavity 111 is less than the second preset value, the processor 30 controls the sterilization device 13 to work; if the microorganism concentration in the first accommodating cavity 111 is greater than or equal to the second preset value, the processor 30 controls the second magnetic field generating device 15 and the degerming device 13 to operate.

The concentration of microorganisms in the first containing chamber 111 is different, and the strength and on-off ratio of the magnetic field generated by the second magnetic field generating device 15 are different. For example, two different values of the concentration of microorganisms are preset in the processor 30: a first preset microorganism concentration value and a second preset microorganism concentration value, wherein the first preset microorganism concentration value is smaller than the second preset microorganism concentration value, and the first preset microorganism concentration value is larger than the second preset value. If the microorganism concentration in the first accommodating cavity 111 is greater than or equal to a second preset value and less than a first preset microorganism concentration value, controlling the magnetic field intensity generated by the first magnetic field generating device 23 to be 0 to 2mt and the on-off ratio to be 30 to 50 percent; if the microorganism concentration in the first accommodating cavity 111 is greater than a first preset microorganism concentration value and less than a second preset microorganism concentration value, the magnetic field intensity generated by the second magnetic field generating device 15 is controlled to be 2mt to 10mt, and the second magnetic field generating device 15 is in a working state.
In some embodiments, please refer to fig. 8, and fig. 8 is a fourth structural diagram of the first fresh keeping container and the interior thereof according to the embodiment of the present disclosure. The refrigerator 100 further includes a first indicator 16, the first indicator 16 is connected to the processor 30, and if the concentration of the microorganisms in the first accommodating cavity 111 is greater than or equal to a third preset value, the processor 30 is further configured to control the first indicator 16 to send an indication message.
Wherein, this first prompting device 16 can be display screen, bee calling organ, alarm and lamp pearl, and correspondingly, this tip information can be text message, prompt tone, glory etc..
It can be set that, when the microorganism concentration in the first accommodating cavity 111 is greater than or equal to the third preset value, which indicates that the microorganism concentration on the object in the first accommodating cavity 111 exceeds the edible standard and the object is not suitable for eating, the processor 30 controls the indicator to send out an indication message to indicate that the user is not suitable for eating.
It can be understood that, by arranging the first prompting device 16, not only can the user be prompted in time that the object in the first accommodating cavity 111 is not suitable for reuse, but also the user can be prompted to clear the object in time, so that the microorganism is prevented from polluting other objects in the first accommodating cavity 111 after the microorganism continues to grow.
In some embodiments, please refer to fig. 9, wherein fig. 9 is a fifth structural diagram of the first freshness retaining container and the interior thereof according to the embodiment of the present disclosure. The first fresh-keeping container 11 has an air inlet 112 and an air outlet 113, the refrigerator 100 further includes a fourth sensor 17 and a fifth sensor 18, the fourth sensor 17 and the fifth sensor 18 are both connected to the processor 30, the fourth sensor 17 is disposed at the air inlet 112 for obtaining the microorganism concentration at the air inlet 112, the fifth sensor 18 is disposed at the air outlet 113 for obtaining the microorganism concentration at the air outlet 113, and the processor 30 is further configured to control the bacteria removing device 13 according to the microorganism concentration at the air inlet 112 and the microorganism concentration at the air outlet 113.
The fourth sensor 17 or the fifth sensor 18 may be a biosensor, which may detect microorganisms and toxins present on the object, detect freshness of the object, and detect pesticide residues on the object. It can be understood that, since the first fresh-keeping container 11 has a refrigeration function, cold air can enter the first accommodating cavity 111 from the air inlet 112, and then exit from the first accommodating cavity 111 through the air outlet 113 to exchange heat with air in the first accommodating cavity 111, thereby implementing the refrigeration function of the first accommodating cavity 111. In the process, since the gas in the first accommodating chamber 111 flows, there may be a difference in the concentration of bacteria at the air inlet 112, the first accommodating chamber 111 and the air outlet 113, so that the processor 30 can control the degerming device 13 according to the concentration of microorganisms at the air inlet 112, the concentration of microorganisms in the first accommodating chamber 111 and the concentration of microorganisms at the air outlet 113.
For example, when the user places the object in the first accommodating chamber 111 at the initial time, the first sensor 12, the fourth sensor 17, and the fifth sensor 18 perform detection to obtain the microorganism concentration a0 in the first accommodating chamber 111, the microorganism concentration b0 at the air inlet 112, and the microorganism concentration c0 at the air outlet 113, respectively. A third preset microorganism concentration value is set in the processor 30, and if a0, b0 or c0 is greater than the third preset microorganism concentration value, the sterilization device 13 is turned on for a period of time, such as 6 hours or 12 hours.
In some embodiments, the refrigerator 100 further includes a blower for regulating a flow rate of the gas in the first fresh food container 11; if the difference between the microorganism concentration in the first accommodating chamber 111, the microorganism concentration at the air inlet 112, and the microorganism concentration at the air outlet 113 is greater than or equal to the preset difference, the processor 30 is further configured to control the rotation speed of the fan to increase the flow speed of the gas in the first accommodating chamber 111.
If the difference between the microorganism concentration in the first accommodating cavity 111, the microorganism concentration at the air inlet 112, and the microorganism concentration at the air outlet 113 is smaller than the preset difference, the processor 30 is further configured to control the rotation speed of the fan to maintain or reduce the flow speed of the gas in the first accommodating cavity 111.
For example, the predetermined difference between the microbe concentration a1 in the first accommodating chamber 111, the microbe concentration b1 at the air inlet 112, and the microbe concentration c1 at the air outlet 113 is 2. When | a1-b1|, | a1-c1| or | b1-c1| is greater than or equal to 2, the rotation speed of the fan is controlled to increase the flow speed of the gas in the first accommodation chamber 111 until | a1-b1|, | a1-c1| or | b1-c1| is less than 2.
In some cases, when | a0-b0|, | a0-c0|, or | b0-c0| is greater than or equal to 2, processor 30 may also increase the operating current of bacteria removing device 13, so that the bacteria removing capability of bacteria removing device 13 is stronger until | a0-b0|, | a0-c0|, or | b0-c0| is less than 2.
In some cases, the processor 30 is further configured to calculate an average value of the microorganism concentration in the first accommodating chamber 111, the microorganism concentration at the air inlet 112, and the microorganism concentration at the air outlet 113, and increase the on-off ratio of the operating time of the degerming device 13 if the average value is greater than a preset average value. In some cases, it is also possible to increase the current through the sterilizing device 13.
For example, the average value of the microorganism concentration a1 in the first accommodating chamber 111, the microorganism concentration b1 at the air inlet 112, and the microorganism concentration c1 at the air outlet 113 is E1 ═ (a1+ b1+ c1)/3, and the preset average value is E2. When the E2-E1 is more than or equal to 1 and less than or equal to 3, the on-off ratio of the degerming device 13 is 31-71 percent; when E2-E1 is more than 3 and less than or equal to 6, the on-off ratio of the degerming device 13 is 31-71%; when E2-E1 is more than 6 and less than or equal to 8, the sterilizing device 13 works all the time, and the current passing through the sterilizing device 13 is 1 to 1.5A; when E2-E1 > 8, the sterilization device 13 is always operating and the current through the sterilization device 13 is 1.2A to 1.5A. The preset average value may be preset by the processor 30, or may be an average value of the microorganism concentration in the first accommodating chamber 111, the microorganism concentration at the air inlet 112, and the microorganism concentration at the air outlet 113 when the user places the object in the first accommodating chamber 111.
In some cases, when the time at which the user places the object in the first accommodating chamber 111 is the initial time, the microorganism concentration a0 in the first accommodating chamber 111, the microorganism concentration b0 at the air inlet 112, and the microorganism concentration c0 at the air outlet 113 at the initial time are (a0+ b0+ c0)/3 on average, and the preset average value of the bacteria concentration in the first accommodating chamber 111 at the initial time is set to E2. The first accommodating chamber 111 is also provided with a second magnetic field generating device 15. When E0 is more than or equal to E2, the second magnetic field generating device 15 does not work; when 0 < (E2-E0)/E2 < 20, the magnetic field intensity of the second magnetic field generating device 15 is 0 to 2mt, and the on-off ratio is 30 to 50 percent; when 30 < (E2-E0)/E2 < 70, the magnetic field intensity of the second magnetic field generating device 15 is 2mt to 10mt, and the on-off ratio is 30 percent to 50 percent; when (E2-E0)/E2 ≧ 70, the user is prompted that the object is inedible.
In some embodiments, with continued reference to fig. 3, the processor 30 is further configured to control the second sensor 22 to obtain the microorganism concentration in the second accommodating chamber 211; if the concentration of the microorganisms in the second accommodating cavity 211 is greater than or equal to a fourth preset value, increasing the on-off ratio or the magnetic field intensity of the magnetic field generating device; if the concentration of the microorganisms in the second accommodating chamber 211 is less than the fourth preset value, the on-off ratio or the magnetic field strength of the second magnetic field generating device 15 is reduced.
For example, when the time when the user places the object in the second accommodating chamber 211 is the initial time, the microorganism concentration in the second accommodating chamber 211 at the initial time is the fourth preset concentration, the microorganism concentration in the second accommodating chamber 211 at the initial time is set as e0, the microorganism concentration in the second accommodating chamber 211 is set as e1, when 0 ≦ e1-e0)/e0 < 20, the on/off ratio of the second magnetic field generating device 15 is 30% -50%, and the magnetic field strength is 0 to 2 mt; when the ratio of (e1-e0)/e0 is more than or equal to 20 and less than or equal to 50, the on-off ratio of the second magnetic field generating device 15 is 40 to 70 percent, and the magnetic field intensity is 0 to 2 mt; when the magnetic field intensity is more than or equal to 50 (e1-e0)/e0 is less than 80, the second magnetic field generating device 15 works continuously, and the magnetic field intensity is 2mt to 10 mt; when (e1-e0)/e0 is equal to or more than 80, the user is prompted that the object is not edible. It is noted that the fourth preset concentration may also be preset in the processor 30.

The sterilization effect means that the magnetic field can change the metabolism mechanism of microorganisms, reduce the relative expression level of bacteria, mold and mycotoxin synthetic gene segments, and effectively inhibit the generation of microbial toxins, thereby achieving the aim of fresh keeping; the antioxidant effect means that the magnetic field can improve the activity of some antioxidant enzymes such as catalase and superoxide dismutase, eliminate hydrogen peroxide and superoxide radical in the food material, and protect the histocyte of the food material from oxidative damage, such as fat oxidation. In addition, the magnetic field generated by the first magnetic field generator 23 can prevent the object from generating large ice crystals during the freezing process, and specifically, the large ice crystals can damage cell walls to cause cytoplasm outflow, thereby causing the reduction of the food quality. When the object is frozen, the freezing speed is gradually reduced from the surface to the center, and the quality of the object is easily reduced due to uneven distribution of the freezing speed. After long-time freezing, large ice crystals can damage the tissue structure of an object, cells cannot restore to the original state after unfreezing, cell sap is greatly lost, and the flavor and the quality of the object are influenced. For example, when a user puts an object into the second receiving cavity 211, the second sensor 22 recognizes microorganisms and toxins present on the object and generates microorganism data, and controls the first magnetic field generating device 23 to operate according to the microorganism data, so that the object is sterilized and resistant to oxidation, and large ice crystals are prevented from being present in the object.
