Embodiments of the present application provide a refrigeration equipment control method and device, a 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 refrigerating device 100 may be, but is not limited to, a refrigerator, a freezer, and other devices that can refrigerate and preserve freshness. Please refer to FIG. 1 and FIG. 2 , FIG. 1 is a schematic diagram of a first structure of a refrigeration device 100 provided by an embodiment of the present application, and FIG. 2 is a schematic diagram of a second structure of the refrigeration device 100 provided by an embodiment of the present application. The refrigeration apparatus 100 includes a storage chamber 110 , a freshness detection module 120 , a magnetic field generating device 130 and a processor 140 .

The storage compartment 110 can store food, such as fruit and vegetable food, meat food, and the like. The refrigeration apparatus 100 may include one or more storage compartments 110 . For example, as shown in FIG. 1 , the refrigeration apparatus 100 includes a first storage compartment 111 and a second storage compartment 112, the first storage compartment 111 can store meat food, the first storage compartment 111 can be a freezing compartment, and the second storage compartment 111 The compartment 112 can store fruits and vegetables, and the second storage compartment 112 can be a refrigerator compartment.

The freshness detection module 120 may be disposed in the storage compartment 110. When the refrigeration apparatus 100 includes multiple storage compartments 110, the refrigeration apparatus 100 may also include multiple freshness detection modules 120, so that one freshness detection module 120 may be disposed in the storage compartment 110. Inside a 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, fruit and vegetable food and meat food both undergo respiration. The freshness detection module 120 can detect the concentration of carbon dioxide in the storage chamber 110 by detecting the freshness. to reflect the current freshness of the food.

The freshness detection module 120 may include an indicator label 121 and a colorimeter 122, the indicator label 121 may be a carbon dioxide indicator label 121, and the indicator label 121 may be made of methyl red and bromothymol blue according to a certain concentration ratio as a sensitive color change indicator. The indicator card is prepared with polylactic acid (PLA) as the base film raw material and cotton fiber paper as the base material. The indicator label 121 is more sensitive to carbon dioxide. The higher the concentration of carbon dioxide, the lower the pH value of the indicator label 121. The indicator label 121 can directly contact the air in the storage room 110 and display different displays according to different concentrations of carbon dioxide. s color.

For example, please refer to FIG. 3 , which is a schematic diagram of a color change of the indicator label 121 shown in FIG. 2 . When the concentration of carbon dioxide in the storage chamber 110 is low, the indicator label 121 is displayed in blue; when the concentration of carbon dioxide in the storage chamber 110 is moderate, the indicator label 121 is displayed in yellow-green; when the concentration of carbon dioxide in the storage chamber 110 is the highest, the indicator The label 121 is displayed in green; when the carbon dioxide concentration in the storage chamber 110 is low again, the indicator label 121 is displayed in yellow.

The colorimeter 122 can monitor the color of the indicator label 121 in real time. For example, the colorimeter 122 can periodically photograph the indicator label 121 to obtain an image of the indicator label 121, and analyze the color change of the indicator label 121 through relevant hardware and software. Thus, the concentration of carbon dioxide in the storage chamber 110 is acquired 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, setting a special solvent, 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 that can obtain the concentration of carbon dioxide in the storage chamber 110 is within the protection scope of the embodiment of the present application.

The magnetic field generating device 130 may be disposed in the storage chamber 110 , for example, on the top cover of the storage chamber 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 can be disposed in one storage compartment 110 . The magnetic field generating device 130 can generate a magnetic field and generate electromagnetic waves, which have high energy and penetrating power, and can destroy the structure of proteins and DNA, thereby realizing the magnetic field preservation function of sterilization and passivation of enzyme activity.

It can be understood that the magnetic field sterilization means that the magnetic field can change the metabolic mechanism of microorganisms, reduce the relative expression levels of bacterial, mold and mycotoxin synthetic gene fragments, and achieve the purpose of effectively inhibiting the production of microbial toxins. Magnetic field blunting of enzymes refers to a scheme in which the activity of an enzyme is reduced by the application of a magnetic field.

The magnetic field generating device 130 may include an electromagnetic control module (not shown in the figure) and a coil module (not shown in the figure). The electromagnetic control module may control the coil module to cut the magnetic field lines to move to generate a magnetic field, and the electromagnetic control module may change the magnitude of the current to generate a magnetic field. In order to change the magnetic field strength of the magnetic field generated by the coil module, different magnetic field preservation functions can be realized.

It can be understood that the coil in the coil module may be made of copper wire material or aluminum wire material, which is not limited in this embodiment of the present application. Meanwhile, the structure of the magnetic field generating device 130 in the embodiment of the present application is not limited to the above examples, for example, the coil module is not used but the iron core module is used. Therefore, the embodiments of the present application do not limit the specific structure of the magnetic field generating device 130 , and any structure of the magnetic field generating device 130 that can realize the magnetic field preservation function falls within the protection scope of the embodiments 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 carbon dioxide obtained by the freshness detection module 120, so that the refrigeration device 100 can Food preservation is controlled according to the current state of the food.

Based on the structure of the above-mentioned refrigeration equipment 100, please refer to FIG. 4, which is a first schematic flowchart of the control method of the refrigeration equipment provided by the embodiment of the present application. The refrigeration equipment control method of the embodiment of the present application may be applied to the refrigeration equipment 100, and the refrigeration equipment 100 may include a storage chamber 110, a freshness detection module 120, and a magnetic field generating device 130; the refrigeration equipment control method may include the following steps:

In 101, control the freshness detection module 120 to obtain the concentration of carbon dioxide in the storage chamber 110;

Foods produce carbon dioxide gas for a variety of reasons as they grow. For example, for meat products, microorganisms can grow and proliferate in meat products, which can lead to stale meat products. During this process, as the number of microorganisms increases, the concentration of carbon dioxide produced by microorganisms through respiration is also higher. For another example, for fruit and vegetable food, fruit and vegetable food can also generate carbon dioxide through respiration, and the concentration of carbon dioxide produced by respiration in the mature stage of fruit and vegetable food is greater than that produced by respiration in the growth and aging stages. Therefore, by obtaining the concentration of carbon dioxide, the freshness of meat food, fruit and vegetable food can be reflected.

The freshness detection module 120 can control the colorimeter 122 to monitor the color of the indicator label 121 in real time, and can obtain the real-time concentration of carbon dioxide in the storage chamber 110 according to the color change.

For example, as shown in FIG. 3 , when the colorimeter 122 detects that the color of the indicator label 121 changes from blue to yellow-green, the refrigeration device 100 may consider that the current concentration of carbon dioxide in the storage room 110 is medium, and the food is in the early stage of production; when the color difference When the color difference meter 122 detects that the color of the indicator label 121 changes from yellow-green to green, the refrigeration device 100 can consider that the current concentration of carbon dioxide in the storage room 110 is the highest, and the food is in the production maturity stage; when the colorimeter 122 detects that the color of the indicator label 121 is changed from The green color turns to yellow again, and the refrigeration device 100 may consider that the current concentration of carbon dioxide in the storage chamber 110 is low, and the food is in the production and death stage.

It can be understood that the corresponding relationship between the color change range of the indicator label 121 and the carbon dioxide concentration can also be pre-stored in the refrigeration device 100. When the colorimeter 122 sends the color change information of the indicator label 121 to the processor 140, the processor 140 can directly The corresponding relationship acquires the current concentration of carbon dioxide in the storage chamber 110 .

It can be understood that, when the freshness detection module 120 detects the carbon dioxide concentration in the storage chamber 110, the detection can be performed when the storage chamber 110 is in a well-sealed state. For example, when the refrigeration device 100 detects that the storage room 110 has just been connected to the outside world, the colorimeter 122 may not collect the color of the freshness detection module 120, or the processor 140 may not analyze the period of time acquired by the colorimeter 122 first. The color of the inner indicator label 121 changes to avoid the problem of inaccurate carbon dioxide concentration due to sealing.

At 102, the magnetic field generated by the magnetic field generator 130 is controlled according to the concentration.

When the refrigeration device 100 obtains the concentration of carbon dioxide in the storage chamber 110 , the refrigeration device 100 can control the magnetic field generating device 130 through the processor 140 to turn on and be in a working state, and the refrigeration device 100 can use the processor 140 to control the magnetic field generating device 130 to generate A magnetic field so that the magnetic field can correspond to the current state of the food in the storage compartment 110 .

For example, when the refrigerating apparatus 100 determines that the food in the storage room 110 is in the production maturity stage according to the concentration of carbon dioxide in the storage room 110, the refrigerating apparatus 100 can use the processor 140 to control the magnetic field with a larger magnetic field intensity generated by the magnetic field generating device 130 to eliminate the bacteria in the storage chamber 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 can be understood that, the refrigeration apparatus 100 can control the magnetic field strength of the magnetic field generated by the magnetic field generating device 130 to be different, and the magnetic field to work for different durations, so that the magnetic field can sterilize or inactivate enzyme activity.

In the refrigeration equipment control method of the embodiment of the present application, the concentration of carbon dioxide in the storage chamber 110 is obtained by controlling the freshness detection module 120, and the magnetic field generated by the magnetic field generating device 130 is controlled according to the concentration. Since the concentration of carbon dioxide can reflect the freshness of the food, the refrigeration equipment control method of the embodiment of the present application can solve the problem that the freshness of the food cannot be differentiated and preserved in the related art. The refrigeration equipment control method of the embodiment of the application is based on The concentration of carbon dioxide in the storage chamber 110 is used to control the magnetic field generated by the magnetic field generating device 130. The refrigeration device 100 can generate different magnetic fields in different states of the food. For example, the refrigeration device 100 can treat the food in an immature state, a mature state, or an aging state Different fresh-keeping controls are performed respectively. The refrigeration device 100 of the embodiment of the present application can perform different fresh-keeping controls on the food according to the current state of the food. The refrigeration device 100 has more flexible fresh-keeping control and better fresh-keeping effect.

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 category of the food stored in the storage chamber 110; controlling the magnetic field generated by the magnetic field generating device 130 according to the concentration, including: controlling according to the concentration and the category The magnetic field generated by the magnetic field generating device 130 .

Different foods have different growth curves and thus different carbon dioxide concentration change curves. Therefore, in the refrigeration equipment control method of the embodiment of the present application, before the magnetic field generator 130 is controlled to generate a magnetic field according to the concentration, the food stored in the storage room 110 can be determined first. category, when the refrigeration device 100 controls the magnetic field generated by the magnetic field generating device 130 according to the concentration and category, the magnetic field can be matched with the type of food and the current growth state of the food, and the refrigeration device 100 can select a freshness control that is more suitable for the current food model.

It can be understood that the refrigeration device 100 can use a camera device to capture images of the food stored in the storage room 110 to obtain the category of the food; an input device can also be set to detect the information about the food category input by the user to obtain the category of the food ; The type of food stored in the storage room 110 can also be determined according to the type of the storage room 110 . It should be noted that the embodiments of the present application do not limit the specific manner in which the refrigeration device 100 obtains the food category, and any manner in which the food category can be determined falls within the protection scope of the embodiments of the present application.

In some embodiments, controlling the freshness detection module 120 to obtain the concentration of carbon dioxide in the storage chamber 110 includes: controlling the colorimeter 122 to monitor the color of the indicator label 121 in real time to obtain the real-time concentration of carbon dioxide in the storage chamber 110; Controlling the magnetic field generated by the magnetic field generating device 130 includes: controlling the magnetic field generated by the magnetic field generating device 130 according to the real-time concentration and type.

The refrigeration device 100 may control the colorimeter 122 to obtain the color of the indicator label 121 within a fixed period of time to obtain the carbon dioxide concentration of the food within the fixed period of time. However, the growth process of food generally goes through the initial growth stage, the mature stable stage, and the decay stage, and the exhalation intensity and the number of microorganisms of the fruit and vegetable food in the early growth stage and the decline stage are roughly equal, so the color difference value detection is in the early growth stage. The concentration of carbon dioxide may be the same at the end of the period, so it is inaccurate to determine the current state of the food based only on the concentration of carbon dioxide at a fixed time.

In the embodiment of the present application, the colorimeter 122 detects the color of the indicator label 121 in real time, and the refrigeration setting can obtain the concentration of carbon dioxide in the storage room 110 in real time. For example, when the concentration of carbon dioxide changes from low to high, it can be determined that the food is in the early stage of growth; when the concentration of carbon dioxide is in the highest value range, it can be determined that the food is in the stable stage of maturity; when the concentration of carbon dioxide changes from high to low, it can be determined Make sure food is dying.

The magnetic field generating device 130 may control the magnetic field generating device 130 to generate different magnetic fields according to real-time concentrations and types. For example, when the real-time concentration is in the first concentration range and the category is the first category, the intensity of the magnetic field generated by the control magnetic field generator 130 is 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 , the intensity of the magnetic field generated by the control magnetic field generating device 130 is within the second magnetic field strength range; when the real-time concentration is within the third concentration range, the magnetic field generating device 130 is controlled not to generate a magnetic field.

It can be understood that the first concentration range may be the same as the second concentration range. Of course, since different food products have different growth curves, the first concentration range may also be different from the second concentration range. For example, when the first category is meat food, the first concentration range may be the concentration of carbon dioxide produced when the microorganisms of the meat food are in a mature and stable period, and when the carbon dioxide concentration monitored by the colorimeter 122 is greater than or equal to the first concentration range At this time, the intensity of the magnetic field generated by the magnetic field generating device 130 can be controlled to be in the first magnetic field intensity range; when the second category is fruit and vegetable food, the second concentration can be the carbon dioxide produced by the respiration of the fruit and vegetable food in the growth and maturity stage When the concentration of carbon dioxide monitored by the colorimeter 122 is greater than or equal to the threshold value of the second concentration range, the intensity of the magnetic field generated by the magnetic field generator 130 can be controlled to be in the second magnetic field intensity range.

It can be understood that the first magnetic field strength range and the second magnetic field strength range may be the same or different. Since the cause of meat food spoilage is the growth of bacteria, the first magnetic field strength mainly plays the role of sterilization and preservation, and the first magnetic field strength can be relatively large; , the second magnetic field strength mainly plays the role of inactivating the activity of the respiration-related enzymes, and the second magnetic field strength may be smaller than the first magnetic field strength.

It can be understood that the third concentration range can be different from the first concentration range and the second concentration range, and the third concentration can be the carbon dioxide concentration generated by fruit and vegetable food or meat food in the dying stage, when the carbon dioxide monitored by the colorimeter 122 When the concentration conforms to the third concentration range, at this time, the magnetic field generating device 130 can be controlled to stop working and not generate a magnetic field.

It can be understood that, for different types of foods, the third concentration range may be different, so that the magnetic field generating device 130 can perform different controls for different foods. Of course, since the concentration of carbon dioxide in the storage chamber 110 is relatively low when the food is in the dying stage, 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 magnetic field in real time according to the real-time concentration and type. For example, please refer to FIG. 5 and FIG. 6 , FIG. 5 is a graph showing the variation of carbon dioxide concentration with time of food stored in the storage chamber 110 of the refrigeration device 100 according to the embodiment of the application, and FIG. A graph showing the variation of the magnetic field strength of the magnetic field generated by the magnetic field generating device 130 of the device 100 with time. Wherein, the curve S1 is the variation curve of the concentration of carbon dioxide in the storage chamber 110 with time, and the curve S2 is the variation curve of the magnetic field intensity of the magnetic field generated by the magnetic field generating device 130 with time; it can be seen from the curves S1 and S2 that the The magnetic field strength of the magnetic field can be positively correlated in real time 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 can first increase and reach a 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 refrigerating apparatus 100 may further control the refrigerating apparatus 100 to issue a reminder signal for indicating that the food is unfit to eat. For example, the refrigeration device 100 can control the indication label 121 to display a color that can indicate "inedible", and the user can use the color to remind the user to deal with the spoiled food in time. For another example, the refrigeration device 100 may also, but is not limited to, be provided with a buzzer module and a prompt light module to remind the user that it is not suitable to eat. It should be noted that, the embodiment of the present application does not specifically limit the reminder signal sent by the refrigeration device 100, and any methods that can achieve the purpose are within the protection scope of the embodiment of the present application.

Based on the above embodiments, for a more detailed understanding of the refrigeration equipment control method provided by the embodiment of the present application, please refer to FIG. 7 , which is a second schematic flowchart of the refrigeration equipment control method provided by the embodiment of the present application. The refrigeration equipment control method may include the following steps:

In 201, the category of the food stored in the storage compartment 110 is determined;

Different foods have different growth curves, which in turn have different carbon dioxide concentration change curves. The refrigeration device 100 can use a camera device to capture images of the food stored in the storage room 110 to obtain the category of the food; an input device can also be set to detect the information about the food category input by the user to obtain the category of the food; The type of the compartment 110 determines the type of food stored in the storage compartment 110 .

In 202, the colorimeter 122 is controlled to monitor the color of the indicator label 121 in real time to obtain the real-time concentration of carbon dioxide in the storage chamber 110;

The colorimeter 122 can detect the color of the indicator label 121 in real time, so that the refrigeration setting can obtain the concentration of carbon dioxide in the storage room 110 in real time, and the refrigeration device 100 can judge the current state of the food according to the change of the carbon dioxide concentration. For example, when the concentration of carbon dioxide changes from low to high, it can be determined that the food is in the early stage of growth; when the concentration of carbon dioxide is in the highest value range, it can be determined that the food is in the stable stage of maturity; when the concentration of carbon dioxide changes from high to low, it can be determined Make sure food is dying.

In 203, when the real-time concentration is in the first concentration range and the category is the first category, the intensity of the magnetic field generated by the magnetic field generating device 130 is controlled to be in the first magnetic field intensity range;

In 204, when the real-time concentration is in the second concentration range and the category is the second category, the intensity of the magnetic field generated by the magnetic field generating device 130 is controlled to be in the 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 real-time concentrations and types. For example, when the first category is meat food, the first concentration range may be the concentration of carbon dioxide produced when the microorganisms of the meat food are in a mature and stable period, and when the carbon dioxide concentration monitored by the colorimeter 122 is greater than or equal to the first concentration range At this time, the intensity of the magnetic field generated by the magnetic field generating device 130 can be controlled to be within the first magnetic field intensity range. When the second category is fruit and vegetable food, the second concentration can be the concentration of carbon dioxide generated by the respiration of the fruit and vegetable food in the growth and maturity stage. When the carbon dioxide concentration monitored by the colorimeter 122 is greater than or equal to the threshold of the second concentration range, then , the intensity of the magnetic field generated by the magnetic field generating device 130 can be controlled to be within the second magnetic field intensity range.

It can be understood that, because the cause of meat food spoilage is the breeding of bacteria, the first magnetic field strength mainly plays the role of sterilization and freshness preservation, and the range of the first magnetic field strength can be large; It is the cause of its own growth, therefore, the second magnetic field strength mainly plays the role of inactivating the activity of the respiration-related enzymes, and the second magnetic field strength range may be smaller than the first magnetic field strength range.
