Detailed Description
The invention aims to provide a refrigerator and a magnetic field intensity adjusting method thereof, which can flexibly adjust the magnetic field intensity according to the content of microorganisms in food while realizing the preservation of a magnetic field, thereby effectively prolonging the preservation period of the food.
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a refrigerator according to the present invention includes a storage compartment 10 for storing food; a magnetic field generator 20 disposed at the top of the storage compartment 10 for generating a magnetic field; the hyperspectral sensor 30 is arranged at the bottom of the storage compartment 10 and is used for detecting the microbial content of the food; and the controller 40 is respectively electrically connected with the magnetic field generator 20 and the hyperspectral sensor 30 and is used for adjusting the magnetic field intensity of the magnetic field generator 20 to the corresponding target magnetic field intensity according to the content of microorganisms so as to prolong the freshness date of the food.
In this embodiment, the magnetic field generator 20 is disposed in the refrigerator, and the magnetic field generator 20 generates a magnetic field, so that the magnetic field sterilization effect on the food can be achieved. Specifically, the magnetic field can change the microbial metabolism mechanism, reduce the relative expression level of bacteria, mold and mycotoxin synthetic gene segments, and effectively inhibit the generation of microbial toxins, thereby realizing the magnetic field preservation. Meanwhile, the hyperspectral sensor 30 is arranged to detect the content of microorganisms in the food stored in the refrigerator by utilizing the characteristic that the hyperspectrum can indicate the number of the microorganisms, then the detected microorganism content is sent to the controller 40, and the controller 40 sets the magnetic field intensity generated in the magnetic field generator 20 according to the content of the microorganisms in the currently stored food, so that the aim of prolonging the freshness date of the food is fulfilled.
Further, the microorganism content determines the freshness of the stored food, and when the microorganism content is high, it indicates that the freshness of the food is low, and when the microorganism content is low, it indicates that the freshness of the food is high, so the controller 40 can be used to judge the freshness of the food according to the microorganism content and output corresponding prompt information, so that the fresh state of the currently stored food can be known in real time and intuitively.
Specifically, the controller 40 is specifically configured to output a first prompt message when the content of the microorganisms is within a first preset range; when the content of the microorganisms is within a second preset range, outputting second prompt information; when the content of the microorganisms is within a third preset range, outputting third prompt information; the food freshness reminding system comprises a food freshness reminding device, a food freshness reminding device and a food freshness reminding device, wherein the first reminding information is used for reminding that the food is fresh, the second reminding information is used for reminding that the food is fresh, the third reminding information is used for reminding that the food is putrefactive, and numerical values of a first preset range, a second preset range and a third preset range are sequentially increased.
For example, if the microorganism content is A, then the first predetermined range may be A.ltoreq.10 4 CFU/g, wherein CFU/g represents the number of bacterial colonies contained in one gram of the sample, and represents the number of microorganisms contained in one gram of the food in the embodiment; the second predetermined range may then be 10 4 CFU/g＜A＜10 6 CFU/g, the third predetermined range may be A ≥ 10 6 CFU/g. When the content of the microorganisms is within a first preset range, the food is fresh and is suitable for use, and a first prompt message is correspondingly output to indicate that the food is fresh. Similarly, when the microorganism content is within a second preset range, the food is indicated to be sub-fresh, and a second prompt message is correspondingly output to indicate that the food is sub-fresh. When the content of the microorganisms is within a third preset range, the food is rotten and can not be used, and correspondingly, a third prompt message is output to indicate that the food is rotten and can not be used, so that the freshness of the food can be known in real time.
Further, the controller 40 is specifically configured to adjust the magnetic field strength to a first target magnetic field strength when the microorganism content is within a first preset range; when the content of the microorganisms is within a second preset range, adjusting the magnetic field strength to a second target magnetic field strength; when the content of the microorganisms is in a third preset range, adjusting the magnetic field strength to a third target magnetic field strength; wherein the first target magnetic field strength is less than the second target magnetic field strength and the third target magnetic field strength is less than the second target magnetic field strength.
For example, the first target magnetic field strength in the present embodiment may be 1mt to 2mt, the second target magnetic field strength may be 8mt to 10mt, and the third target magnetic field strength may be 4mt to 6 mt. When the content of the microorganisms is within a first preset range, the food is fresh, and the magnetic field intensity can be adjusted to be lower; if the content of the microorganisms is within the second preset range, and the food is fresh again, in order to prolong the preservation period, the magnetic field intensity is correspondingly increased so as to increase the preservation strength. If the microorganism content is within the third predetermined range, the food is spoiled, and the magnetic field strength can be reduced to achieve the purpose of energy saving.
When the content of the microorganisms is within a third preset range, the controller 40 may directly control the magnetic field generator 20 to be turned off and stopped, which is equivalent to that the third target magnetic field strength may also be 0. If the content of the microorganisms is within the third preset range, the food is decayed, so that the food does not need to be kept fresh, the magnetic field generator 20 can be directly controlled to be turned off, and the aim of saving energy is fulfilled.
Further, referring to fig. 2, the refrigerator further includes a voice module 50; the voice module 50 is connected with the controller 40; the voice module 50 is configured to output the first prompt message, the second prompt message, or the third prompt message output by the controller 40. That is, in this embodiment, the first prompt message, the second prompt message, and the third prompt message may be voice prompt messages, and the controller 40 controls the voice module 50 to send out corresponding prompt messages according to the content of the microorganisms, so as to know the current fresh-keeping state of the refrigerator in time.
Further, referring to fig. 3, the refrigerator may further include a display module 60, and the display module 60 is connected to the controller 40; the display module 60 is configured to display the first prompt message, the second prompt message or the third prompt message output by the controller 40. The first prompt message, the second prompt message and the third prompt message in this embodiment may be display prompt messages, for example, the display messages may be displayed through lights, or the display screen may directly display the prompt messages, or the indication lights and the display screen may be simultaneously displayed. For example, when the content of the microorganisms is in a first preset range, the microorganisms can be displayed as green through the display module 60, and a first prompt message is displayed; when the content of the microorganisms is in a second preset range, the display module 60 can display yellow and second prompt information; when the microorganism content is in the third preset range, the display module 60 can display red and display third prompt information to achieve the effect of visual prompt. At present, the voice module 50 and the display module 60 may be set simultaneously, the voice module 50 sends out corresponding voice prompt information, and the display module 60 displays different colors for indication, so the presentation form of the prompt information is not particularly limited in the present invention.
