Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to fig. 1 to 11 in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a refrigeration equipment control method and device, refrigeration equipment 100 and a storage medium. The refrigeration equipment control method may be executed by the refrigeration equipment control device 200 or by the refrigeration equipment 100. The refrigeration device 100 may be, but is not limited to, a refrigerator, a freezer, or other devices capable of refrigerating and preserving freshness. Referring to fig. 1 and fig. 2, fig. 1 is a first structural schematic diagram of a refrigeration apparatus 100 according to an embodiment of the present application, and fig. 2 is a second structural schematic diagram of the refrigeration apparatus 100 according to the embodiment of the present application. The refrigeration apparatus 100 includes a storage compartment 110, a freshness detection module 120, a magnetic field generating device 130, and a processor 140.
The storage compartment 110 may store food items, such as fruit and vegetable food items, meat food items, and the like. The refrigeration appliance 100 may include one or more storage compartments 110. For example, as shown in fig. 1, the refrigerating apparatus 100 includes a first storage compartment 111 and a second storage compartment 112, the first storage compartment 111 may store meat products, the first storage compartment 111 may be a freezing compartment, the second storage compartment 112 may store fruit and vegetable products, and the second storage compartment 112 may be a refrigerating compartment.
The freshness detection module 120 can be disposed in the storage compartment 110, and when the refrigeration apparatus 100 includes a plurality of storage compartments 110, the refrigeration apparatus 100 can also include a plurality of freshness detection modules 120, so that one freshness detection module 120 can be disposed in one storage compartment 110. The freshness detection module 120 can detect the current freshness of the food according to the production parameters of the food, for example, the fruit and vegetable food and the meat food can both breathe, and the freshness detection module 120 can reflect the current freshness of the food by detecting the concentration of carbon dioxide in the storage chamber 110.
The freshness detection module 120 may include an indication label 121 and a color difference meter 122, the indication label 121 may be a carbon dioxide indication label 121, and the indication label 121 may be an indication card prepared from methyl red and bromothymol blue as a sensitive color change indicator according to a certain concentration ratio, polylactic acid (PLA) as a base film material, and cotton fiber paper as a base material. This instruction label 121 is comparatively sensitive to carbon dioxide, and the concentration of carbon dioxide is bigger, and instruction label 121 thinks that its pH value (PH value) is littleer, and instruction label 121 can direct and the air contact in the storage room 110 and according to the concentration of different carbon dioxide and show different colours.
For example, referring to fig. 3, fig. 3 is a schematic diagram illustrating a color change of the indicator 121 shown in fig. 2. When the concentration of carbon dioxide in the storage chamber 110 is small, the indication label 121 appears blue; when the concentration of carbon dioxide in the storage chamber 110 is moderate, the indication label 121 is displayed in yellow-green; when the concentration of carbon dioxide in the storage chamber 110 is the highest, the indication label 121 displays green; when the carbon dioxide concentration in the storage chamber 110 is again small, the indication label 121 appears yellow.
The color difference meter 122 may monitor the color of the indication label 121 in real time, for example, the color difference meter 122 may periodically photograph the indication label 121 and obtain an image of the indication label 121, and analyze a color change condition of the indication label 121 through related hardware and software, so as to obtain the concentration of the carbon dioxide in the storage compartment 110 in real time. It should be noted that the freshness detection module 120 can also obtain the concentration of carbon dioxide in other ways, for example, a special solvent is provided, which can absorb carbon dioxide and display different colors according to the concentration of carbon dioxide. Therefore, the embodiment of the present application does not limit the specific structure of the freshness detection module 120, and any structure capable of obtaining the concentration of the carbon dioxide in the storage chamber 110 is within the scope of the embodiment of the present application.
The magnetic field generating device 130 may be disposed within the storage compartment 110, for example, on a top cover of the storage compartment 110. When the refrigeration apparatus 100 includes a plurality of storage compartments 110, the refrigeration apparatus 100 may also include a plurality of magnetic field generating devices 130, so that one magnetic field generating device 130 may be disposed in one storage compartment 110. The magnetic field generator 130 can generate a magnetic field and generate electromagnetic waves, which have high energy and penetrating power and can destroy the structures of proteins and DNA, thereby realizing the magnetic field fresh-keeping functions of sterilization and enzyme activity inactivation.
It is understood that magnetic field sterilization means that the magnetic field can change the metabolism mechanism of the microorganism, reduce the relative expression level of the synthetic gene segments of bacteria, mold and mycotoxin and achieve the purpose of effectively inhibiting the generation of the microbial toxins. Magnetic field-inactive enzymes refer to protocols in which the activity of the enzyme is reduced by the application of a magnetic field.
The magnetic field generating device 130 may include an electromagnetic control module (not shown) and a coil module (not shown), wherein the electromagnetic control module may control the coil module to cut the magnetic field lines to generate a magnetic field, and the electromagnetic control module may change the magnetic field intensity of the magnetic field generated by the coil module by changing the magnitude of the current, so as to achieve different magnetic field fresh-keeping functions.
It can be understood that the coil in the coil module may be made of a copper wire material or an aluminum wire material, which is not limited in the embodiment of the present application. Meanwhile, the structure of the magnetic field generating device 130 according to the embodiment of the present application is not limited to the above example, and for example, a core module is used instead of a coil module. Therefore, the specific structure of the magnetic field generating device 130 is not limited in the embodiment of the present application, and all structures of the magnetic field generating device 130 that can achieve the magnetic field preservation function are within the protection scope of the embodiment of the present application.
The processor 140 may be electrically connected to the freshness detection module 120 and the magnetic field generating device 130, respectively, and the processor 140 may control the magnetic field generated by the magnetic field generating device 130 according to the concentration of the carbon dioxide obtained by the freshness detection module 120, so that the refrigeration apparatus 100 can perform freshness keeping control on the food according to the current state of the food.
Based on the structure of the refrigeration equipment 100, please refer to fig. 4, and fig. 4 is a first flowchart of a control method of the refrigeration equipment according to the embodiment of the present application. The refrigeration apparatus control method of the embodiment of the present application may be applied to a refrigeration apparatus 100, and the refrigeration apparatus 100 may include a storage compartment 110, a freshness detection module 120, and a magnetic field generation device 130; the refrigeration equipment control method can comprise the following steps:
in 101, the freshness detection module 120 is controlled to obtain the concentration of carbon dioxide in the storage compartment 110;
during the growth of food products carbon dioxide gas is produced for a number of reasons. For example, in the case of meat products, microorganisms can grow and proliferate in the meat product and can cause the meat product to be stale, in which process the concentration of carbon dioxide produced by the microorganisms through respiration increases as the number of microorganisms increases. For example, in the case of fruit and vegetable foods, the fruit and vegetable foods may also produce carbon dioxide by respiration, and the concentration of carbon dioxide produced by respiration in the mature stage of the fruit and vegetable foods is greater than that produced by respiration in the mature and aging stages. Therefore, the freshness of meat food, fruit and vegetable food can be reflected by obtaining the concentration of the carbon dioxide.
The freshness detection module 120 can control the color difference meter 122 to monitor the color of the indication label 121 in real time, and the real-time concentration of the carbon dioxide in the storage compartment 110 can be obtained according to the color change.
For example, as shown in fig. 3, when the color difference meter 122 detects that the color of the indication label 121 changes from blue to yellow-green, the refrigeration device 100 may consider that the concentration of the carbon dioxide in the storage compartment 110 is medium, and the food is in the initial stage of production; when the color difference meter 122 detects that the color of the indication label 121 changes from yellow green to green, the refrigeration device 100 may determine that the concentration of the carbon dioxide in the storage compartment 110 is the highest, and the food is in the production maturity stage; when the color difference meter 122 detects that the color of the indication label 121 changes from green to yellow again, the refrigeration device 100 may consider that the concentration of carbon dioxide in the storage compartment 110 is low and the food is in a production decline period.
It is understood that, the inside of the refrigeration apparatus 100 may also store the corresponding relationship between the color change range of the indication tag 121 and the concentration of the carbon dioxide in advance, and when the color difference meter 122 sends the color change information of the indication tag 121 to the processor 140, the processor 140 may directly obtain the concentration of the carbon dioxide in the current storage compartment 110 according to the corresponding relationship.
It can be understood that the freshness detection module 120 can detect the concentration of carbon dioxide in the storage room 110 when the storage room 110 is in a state of good sealing. For example, when the refrigeration device 100 detects that the storage compartment 110 is just communicated with the outside, the color difference meter 122 may not collect the color of the freshness detection module 120, or the processor 140 may not analyze the color change of the indication label 121 obtained by the color difference meter 122 during the period of time, so as to avoid the problem of inaccurate carbon dioxide concentration due to the sealing property.
At 102, the magnetic field generated by the magnetic field generating device 130 is controlled according to the concentration.
When the refrigeration device 100 obtains the concentration of the carbon dioxide in the storage compartment 110, the refrigeration device 100 may control the magnetic field generating device 130 to be turned on and be in a working state through the processor 140, and the refrigeration device 100 may control the magnetic field generated by the magnetic field generating device 130 through the processor 140, so that the magnetic field may correspond to the current state of the food in the storage compartment 110.
For example, when the refrigeration apparatus 100 determines that the food in the storage compartment 110 is in the production maturity stage according to the concentration of the carbon dioxide in the storage compartment 110, the refrigeration apparatus 100 may control the magnetic field with the larger magnetic field intensity generated by the magnetic field generating device 130 through the processor 140 to destroy bacteria in the storage compartment 110 and inhibit the generation of microorganisms, or inactivate the activity of respiration-related enzymes in the food to inhibit the respiration of the food.
It is understood that the refrigeration apparatus 100 can control the magnetic field generated by the magnetic field generating device 130 to have different magnetic field strengths and different time periods during which the magnetic field is operated, so that the magnetic field can be sterilized or the enzymatic activity can be inactivated.
In the refrigeration apparatus control method according to the embodiment of the application, the freshness detection module 120 is controlled to obtain the concentration of the carbon dioxide in the storage compartment 110, and the magnetic field generated by the magnetic field generation device 130 is controlled according to the concentration. The concentration of the carbon dioxide can reflect the freshness of the food, so that the refrigeration equipment control method in the embodiment of the application can solve the problem that the food cannot be preserved differently according to the freshness of the food in the related art, the refrigeration equipment control method in the embodiment of the application controls the magnetic field generated by the magnetic field generating device 130 according to the concentration of the carbon dioxide in the storage chamber 110, the refrigeration equipment 100 can generate different magnetic fields in different states of the food, for example, the refrigeration equipment 100 can respectively perform different preservation controls on the food in an immature state, a mature state and an aging state, the refrigeration equipment 100 in the embodiment of the application can perform different preservation controls on the food according to the current state of the food, the preservation control of the refrigeration equipment 100 is more flexible, and the preservation effect is more excellent.
In some embodiments, before controlling the magnetic field generated by the magnetic field generating device 130 according to the concentration, the method further includes: determining the type of food items stored within the storage compartment 110; the magnetic field generated by the concentration-controlled magnetic field generating device 130 includes: the magnetic field generated by the magnetic field generating device 130 is controlled according to the concentration and the type.
Therefore, the control method of the refrigeration apparatus in the embodiment of the present application may further determine the type of the food stored in the storage compartment 110 before controlling the magnetic field generating device 130 to generate the magnetic field according to the concentration, and when the refrigeration apparatus 100 controls the magnetic field generated by the magnetic field generating device 130 according to the concentration and the type, the magnetic field may be matched with the type of the food and the current growth state of the food, and the refrigeration apparatus 100 may select a preservation control mode more suitable for the current food.
It is understood that the refrigeration apparatus 100 may capture an image of the food stored in the storage compartment 110 by using a camera apparatus to obtain the category of the food; an input device can also be arranged and information about food categories input by a user is detected to acquire the categories of the food; the type of food items stored in the storage compartment 110 may also be determined according to the type of storage compartment 110. It should be noted that, the embodiment of the present application does not limit the specific manner in which the refrigeration apparatus 100 obtains the food category, and all the manners in which the food category can be determined are within the scope of the embodiment of the present application.
In some embodiments, controlling the freshness detection module 120 to obtain the concentration of carbon dioxide within the storage compartment 110 includes: controlling the color difference meter 122 to monitor the color of the indication label 121 in real time to obtain the real-time concentration of the carbon dioxide in the storage chamber 110; controlling the magnetic field generated by the magnetic field generating device 130 according to the concentration and the type includes: the magnetic field generated by the magnetic field generating device 130 is controlled according to the real-time concentration and the type.
The refrigeration apparatus 100 may control the color difference meter 122 to acquire the color of the indication label 121 for a fixed period of time to acquire the carbon dioxide concentration of the food item for the fixed period of time. However, the food generally goes through an initial growth stage, a stable maturation stage and a decay stage, and the expiration intensities of the fruit and vegetable foods in the initial growth stage and the decay stage are approximately equal, and the number of microorganisms is also approximately equal, so that the concentrations of carbon dioxide in the initial growth stage and the decay stage detected by the color difference value may be the same, and therefore, the current state of the food is not accurately determined only according to the carbon dioxide concentration at a certain fixed time.
The color difference meter 122 in the embodiment of the present application detects the color of the indication label 121 in real time, the refrigeration setting can obtain the concentration of carbon dioxide in the storage room 110 in real time, and the refrigeration device 100 can determine the current state of the food according to the change of the concentration of carbon dioxide. For example, when the concentration of carbon dioxide varies from low to high, it can be determined that the food is in the early stage of growth; when the concentration of the carbon dioxide is in the highest value range, the food can be determined to be in a mature stable period; when the concentration of carbon dioxide changes from high to low, the food can be determined to be in the decline period.
The magnetic field generating device 130 may control the magnetic field generating device 130 to generate different magnetic fields according to the real-time concentration and the type. For example, when the real-time concentration is in the first concentration range and the category is the first category, the strength of the magnetic field generated by the magnetic field generation device 130 is controlled to be in the first magnetic field strength range; when the real-time concentration is in the second concentration range and the category is the second category, controlling the strength of the magnetic field generated by the magnetic field generating device 130 to be in the second magnetic field strength range; and controlling the magnetic field generating device 130 not to generate the magnetic field when the real-time concentration is in the third concentration range.
It is understood that the first concentration range may be the same as the second concentration range. Of course, the first concentration range may also be different from the second concentration range, since different food products have different growth curves. For example, when the first category is meat products, the first concentration range may be the concentration of carbon dioxide generated when the microorganisms of the meat products are in the maturation and stabilization period, and when the concentration of carbon dioxide monitored by the color difference meter 122 is greater than or equal to the threshold value of the first concentration range, the intensity of the magnetic field generated by the magnetic field generating device 130 may be controlled to be in the first magnetic field intensity range; when the second category is fruit and vegetable food, the second concentration may be the concentration of carbon dioxide generated by respiration of the fruit and vegetable food in the growth and maturation stage, and when the concentration of carbon dioxide monitored by the color difference meter 122 is greater than or equal to the threshold value of the second concentration range, the strength of the magnetic field generated by the magnetic field generating device 130 may be controlled to be in the second magnetic field strength range.
It will be appreciated that the first and second magnetic field strength ranges may be the same or different. Because the spoilage reason of the meat products is the breeding of bacteria, the first magnetic field intensity mainly plays a role in sterilization and preservation, and can be larger; the second magnetic field strength mainly plays a role in inactivating the activity of respiration-related enzymes, and can be smaller than the first magnetic field strength because the fruit and vegetable food spoilage is mainly caused by self growth.
It is understood that the third concentration range may be different from the first concentration range and the second concentration range, and the third concentration range may be the concentration of carbon dioxide generated when the fruit, vegetable or meat food is in the death phase, and when the concentration of carbon dioxide monitored by the color difference meter 122 meets the third concentration range, the magnetic field generating device 130 may be controlled to stop working and not generate the magnetic field.
It will be appreciated that the third concentration range may be different for different types of food products, so that the magnetic field generating means 130 may be controlled differently for different food products. Of course, since the concentration of carbon dioxide in the storage compartment 110 is low when the food is in the decline period, the refrigeration apparatus 100 can select the same third concentration range for control even for different types of food.
In some embodiments, the refrigeration device 100 can also control the magnetic field generating device 130 to change the magnetic field strength of the generated magnetic field in real time according to the real-time concentration and the type. For example, referring to fig. 5 and fig. 6, fig. 5 is a graph illustrating a change of a carbon dioxide concentration of food stored in the storage chamber 110 of the refrigeration apparatus 100 according to an embodiment of the present application with time, and fig. 6 is a graph illustrating a change of a magnetic field strength of a magnetic field generated by the magnetic field generating device 130 of the refrigeration apparatus 100 according to an embodiment of the present application with time. Wherein, the curve S1 is a time-varying curve of the concentration of carbon dioxide in the storage chamber 110, and the curve S2 is a time-varying curve of the magnetic field strength of the magnetic field generated by the magnetic field generator 130; as can be seen from the curves S1 and S2, the magnetic field strength of the magnetic field generated by the magnetic field generating device 130 may change in a real-time positive correlation manner with the change of the real-time concentration of carbon dioxide, and the magnetic field strength of the magnetic field generated by the magnetic field generating device 130 may first increase and reach the peak and then gradually decrease until the magnetic field is turned off.
In some embodiments, after the magnetic field generating device 130 turns off the magnetic field, the control of the refrigeration apparatus 100 may also control the refrigeration apparatus 100 to emit an alert signal indicating that the food is not suitable for consumption. For example, the refrigeration device 100 may control the indicator tab 121 to display a color that indicates "inedible," and the user may prompt the user to treat the spoiled food item in a timely manner. For another example, the refrigeration device 100 may further include, but is not limited to, a buzzer module and a warning light module to warn a user that the refrigeration device is not suitable for eating. It should be noted that, the embodiment of the present application does not specifically limit the manner in which the reminding signal is sent by the refrigeration apparatus 100, and all the manners that can achieve the purpose are within the scope of the embodiment of the present application.
Based on the foregoing embodiments, please refer to fig. 7 for more detailed understanding of the method for controlling a refrigeration apparatus provided in the embodiments of the present application, and fig. 7 is a second flowchart of the method for controlling a refrigeration apparatus provided in the embodiments of the present application. The refrigeration equipment control method can comprise the following steps:
in 201, determining a category of food items stored within the storage compartment 110;
different foods have different growth curves and thus different carbon dioxide concentration variation curves. The refrigeration apparatus 100 may acquire an image of the food stored in the storage compartment 110 using a camera apparatus to acquire the category of the food; an input device can also be arranged and information about food categories input by a user is detected to acquire the categories of the food; the type of food items stored in the storage compartment 110 may also be determined according to the type of storage compartment 110.
At 202, controlling the color difference meter 122 to monitor the color of the indication label 121 in real time to obtain the real-time concentration of the carbon dioxide in the storage chamber 110;
the color difference meter 122 can detect the color of the indication label 121 in real time, so that the refrigeration setting can obtain the concentration of carbon dioxide in the storage chamber 110 in real time, and the refrigeration device 100 can judge the current state of the food according to the change of the concentration of the carbon dioxide. For example, when the concentration of carbon dioxide varies from low to high, it can be determined that the food is in the early stage of growth; when the concentration of the carbon dioxide is in the highest value range, the food can be determined to be in a mature stable period; when the concentration of carbon dioxide changes from high to low, the food can be determined to be in the decline period.
In 203, when the real-time concentration is in a first concentration range and the category is a first category, controlling the intensity of the magnetic field generated by the magnetic field generating device 130 to be in a first magnetic field intensity range;
in 204, when the real-time concentration is in a second concentration range and the category is a second category, controlling the intensity of the magnetic field generated by the magnetic field generating device 130 to be in a second magnetic field intensity range;
the magnetic field generating device 130 may control the magnetic field generating device 130 to generate different magnetic fields according to the real-time concentration and the type. For example, when the first category is meat products, the first concentration range may be the concentration of carbon dioxide generated when the microorganisms of the meat products are in the maturation stability period, and when the concentration of carbon dioxide monitored by the color difference meter 122 is greater than or equal to the threshold value of the first concentration range, the intensity of the magnetic field generated by the magnetic field generating device 130 may be controlled to be in the first magnetic field intensity range. When the second category is fruit and vegetable food, the second concentration may be the concentration of carbon dioxide generated by respiration of the fruit and vegetable food in the growth and maturation stage, and when the concentration of carbon dioxide monitored by the color difference meter 122 is greater than or equal to the threshold value of the second concentration range, the strength of the magnetic field generated by the magnetic field generating device 130 may be controlled to be in the second magnetic field strength range.
It can be understood that, because the putrefaction of meat products is the breeding of bacteria, the first magnetic field strength mainly plays a role in sterilization and preservation, and the first magnetic field strength range can be larger; the second magnetic field strength mainly plays a role in inactivating the activity of respiration-related enzymes, and the second magnetic field strength range can be smaller than the first magnetic field strength range, because the fruit and vegetable food spoilage is mainly caused by self growth.
In 205, controlling the magnetic field generating device 130 not to generate a magnetic field when the real-time concentration is in the third concentration range;
at 206, the refrigeration appliance 100 is controlled to emit an alert indicating that the food product is not suitable for consumption.
The third concentration range may be different from the first concentration range and the second concentration range, and the third concentration range may be the concentration of carbon dioxide generated when the fruit, vegetable or meat food is in the death phase, and when the concentration of carbon dioxide monitored by the color difference meter 122 conforms to the third concentration range, the magnetic field generating device 130 may be controlled to stop working and not generate the magnetic field.
After the magnetic field generating device 130 turns off the magnetic field, the control of the refrigeration apparatus 100 may also control the refrigeration apparatus 100 to emit a warning signal indicating that the food is not suitable for eating. For example, the refrigeration device 100 may control the indicator tab 121 to display a color that indicates "inedible," and the user may prompt the user to treat the spoiled food item in a timely manner via the color. It should be noted that, the embodiment of the present application does not specifically limit the manner in which the reminding signal is sent by the refrigeration apparatus 100, and all the manners that can achieve the purpose are within the scope of the embodiment of the present application.
According to the refrigeration equipment control method, the magnetic field generated by the magnetic field generating device 130 is controlled in real time according to the type of food and the acquired real-time concentration of carbon dioxide in the storage chamber 110, the refrigeration equipment 100 can select different control threshold values according to different foods, and the current growth state of the food can be accurately judged according to the real-time concentration of the carbon dioxide, so that the refrigeration equipment 100 can perform more accurate magnetic field control, and the magnetic field preservation effect of the refrigeration equipment 100 is more excellent.
In order to reduce the difficulty of determining the food category, before controlling the magnetic field generated by the magnetic field generating device 130 according to the concentration, the method may further include: determining the type of the storage room 110 according to the function of the storage room 110; the controlling the magnetic field generated by the magnetic field generating device 130 according to the concentration may include: the magnetic field generated by the magnetic field generating device 130 is controlled according to the concentration and type. Controlling the freshness detection module 120 to obtain the concentration of carbon dioxide in the storage compartment 110 may include: controlling the color difference meter 122 to monitor the color of the indication label 121 in real time to obtain the real-time concentration of the carbon dioxide in the storage chamber 110; controlling the magnetic field generated by the magnetic field generating device 130 according to the concentration and the type includes: the magnetic field generated by the magnetic field generating device 130 is controlled according to the real-time concentration and type.
