Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a food preservation method includes steps S300, S400 and S700.
Step S300, when the storage chamber stores food, food type information is obtained.
In particular, the storage compartment is used to store food that is optimally stored in the same environment. It is understood that it is possible to guide the user to place the same food in the same storage compartment in the optimal storage environment by setting corresponding identification information in the storage compartment. Further, the setting manner of the identification information is not unique, and in one embodiment, a corresponding label (such as an image label or a text label) may be attached to an outer wall of each storage compartment, and a user may put a corresponding type of food into the storage compartment according to the label. In another embodiment, the storage device may be provided with a display device, and the display device displays the food or the food type with the same optimal storage environment, so that the user can directly place the food with the same optimal storage environment in the same storage compartment when performing the fresh-keeping storage of the food.
The optimal storage environment is an environment corresponding to the condition that the loss of the food nutrient components is the slowest, and can be realized by controlling the temperature, the humidity, the carbon dioxide concentration or the oxygen concentration and the like in the storage environment at a certain value. It should be noted that the way of obtaining the food category information is not exclusive, and in one embodiment, it may be that the storage device corresponding to the storage compartment is provided with means for human-computer interaction, and when the user puts the food into the storage compartment, the user can manually input the food category information and in which storage compartment the food is placed, etc. In another embodiment, the matching analysis can be performed by the controller according to preset image information after the image acquisition is performed by the image acquisition device arranged in the storage compartment. It will be appreciated that the number of storage compartments is not exclusive and that one or more storage compartments may be provided in the same storage device (e.g. in the same refrigerator) as long as the optimal storage environment for the food stored in each storage compartment is the same, and that during actual operation the controller directly makes storage environment adjustments to the storage compartments in which the food is stored, and for storage compartments in which no food is stored will switch off its refrigeration or freezing function.
And step S400, analyzing according to the food type information and a preset environment parameter database to obtain corresponding optimal storage environment information.
Specifically, the preset environment parameter database stores optimal storage environment information when different food category information is stored. The storage environment information is used for representing the environment state of the storage room, and the corresponding required optimal storage environment type can be intuitively obtained according to the storage environment information. After the controller knows the food type information stored in a certain storage compartment, the controller matches the food type information with a preset environment parameter database according to the food type information to obtain the optimal storage environment information corresponding to the food type information (or the food), namely, when the food of the type is kept fresh, if the loss of nutrient components and the like is ensured to be the slowest, the optimal storage environment information corresponds to the required storage environment. It should be noted that, in one embodiment, the controller is in communication connection with an external server, and after the controller obtains the food type information or the picture information of the food stored in the storage chamber, the controller can send the food type information or the food image information to the server for searching, so as to directly obtain the corresponding optimal storage environment information.
For example, in an embodiment, taking an apple as an example, after the food is stored in one of the storage compartments and the controller detects (or inputs by the user) that the food is the apple, the controller performs analysis according to the preset environment parameter database to obtain the corresponding optimal storage environment information: the storage temperature is 0 +/-0.5 ℃, the storage humidity is 85-90%, and the carbon dioxide concentration is 75% (apples have a breathing effect and should be inhibited by increasing the carbon dioxide concentration).
It should be noted that, in one embodiment, after the controller obtains the optimal storage environment information according to the food category information, the food category information and the corresponding optimal storage environment information are also output to the corresponding display device for displaying, and the user can timely know, so that when the food category information and the like are wrong, the user can timely know and perform further correction operation. Furthermore, in an embodiment, the user may further adjust the optimal storage environment information according to the user's own requirements, so that the controller performs corresponding control operations according to the optimal environment information adjusted by the user in the subsequent operation process.
And step S700, sending an adjusting instruction to an environment adjusting device according to the analyzed optimal storage environment information.
Specifically, the adjustment instruction is used for controlling the environment adjustment device to adjust the storage environment of the storage room, so that the storage environment of the storage room is consistent with the analyzed optimal storage environment information. After the controller obtains the optimal storage environment information corresponding to the food type information, the controller adjusts the storage environment of the storage chamber according to the environment adjusting device, so that the storage environment of the storage chamber meets the requirement of the optimal storage environment information, the loss of nutritional ingredients and the like of the food in the storage environment is ensured to be slowest, and the food fresh-keeping operation is realized.
It should be noted that the type of the environment adjusting means is not necessarily unique, and for different types of storage environment information, the adjustment may be performed by different environment adjusting means, and for the case where the storage environment information includes more kinds of parameters at the same time, the environment adjusting means will include a plurality of types of adjusters at the same time as long as the storage environment can be adjusted to be consistent with the optimum storage environment information. For example, in an embodiment, also taking an apple as an example, the apple corresponds to the optimal storage environment information including temperature, humidity and carbon dioxide concentration, and the corresponding environment adjusting device will include a device for adjusting temperature, a device for adjusting humidity and a device for adjusting carbon dioxide concentration.
Referring to fig. 2, in an embodiment, before step S300, the method further includes step S100 and step S200.
Step S100, obtaining internal image information of the storage compartment.
Specifically, the internal image information is acquired by an image acquisition device arranged in the storage chamber. In this embodiment, the storage compartment is provided with an image acquisition device inside, the image acquisition device can obtain the image information inside the storage compartment, and further image recognition processing according to the internal image information will obtain whether the storage compartment has food or not. It should be noted that, since the number of storage compartments is not unique in the entire storage apparatus, and the number of corresponding image capturing devices is not unique, a corresponding image capturing device is provided in each storage compartment to perform an internal image capturing operation of the storage compartment. In one embodiment, the image acquired by the image acquisition device can also be used for the identification operation of the food type information.
it can be understood that the setting position of the image acquisition device in the storage chamber is not unique, and the image acquisition of the whole interior of the storage chamber can be realized. For example, in one embodiment, the image capture device is disposed on the top of the storage compartment. It should be noted that the type of image capturing device is not exclusive and may be a camera or an image recognition sensor, etc., as long as image capturing inside the storage compartment is enabled.
And step S200, judging whether the storage chamber stores food or not according to the internal image information.
Specifically, after the controller obtains the internal image information of the storage chamber, the internal image information is compared with the stored preset image information for analysis, so as to obtain a comparison result of the food stored in the storage chamber. If yes, it means that the storage compartment stores food, and step S300 is executed to obtain food type information in order to ensure that the food is stored in an optimal storage environment for fresh-keeping storage.
In one embodiment, when it is determined from the internal image information that the storage compartment does not store food, the method further includes: and closing the refrigerating function or the freezing function of the storage chamber, and returning to obtain the internal image information of the storage chamber.
specifically, please refer to fig. 3 in combination, the image capturing operation of the image capturing device is performed in real time, when the controller determines according to the internal image information of the storage compartment, a situation that the storage compartment does not store food may occur, and at this time, there is no need to refrigerate for refrigeration or freezing, and the controller controls the corresponding refrigeration or freezing function in the storage compartment to be turned off, so as to avoid waste of electric energy. Meanwhile, the controller acquires the internal image information acquired and sent by the image acquisition device in real time, so that the controller can know the internal image information in time when food is put into the storage room. It is understood that the manner in which the controller turns off the refrigerating or freezing function of the storage compartment is not exclusive, and the compressor of the refrigerator may be directly turned off, or a valve of the air supply duct corresponding to the storage compartment may be turned off to stop supplying cold air to the corresponding storage compartment.
Referring to fig. 4, in an embodiment, before step S700, the method further includes step S500 and step S600.
Step S500, obtaining the environmental state parameters of the storage room.
Specifically, the environmental state parameters are acquired by an environment acquisition device arranged in the storage chamber. And each storage chamber of the storage equipment is provided with a corresponding environment acquisition device for acquiring parameter information of the storage environment of the storage chamber. It can be understood that the specific types of the corresponding environment acquisition devices are different according to the inconsistency of the acquired environment state parameters. For example, a temperature collector for collecting ambient temperature and a humidity collector for collecting ambient humidity can be used as the ambient collection devices to be disposed in each storage chamber, and in the actual operation process, which type of ambient collection device is specifically adopted should be confirmed by the user or the specific type of the storage device.
Step S600, outputting the environment state parameters to the corresponding display device for displaying.
specifically, in this embodiment, the storage device is further provided with a display device, and after the environment state parameters of each compartment are acquired by the environment acquisition device, the acquired state parameters are sent to the display device to be displayed, so that the user can timely know the storage environment information of each storage compartment.
It should be noted that in one embodiment, the environmental condition parameters are collected in real time by the environmental collection device, and after the storage device is started, the environmental collection device starts to collect the environmental condition parameters of all the storage compartments in the storage device. In another embodiment, the environment acquisition device may start the acquisition operation of the environment state parameters for the storage chamber in which the food is stored only when the controller analyzes the internal image information acquired by the image acquisition device and obtains that the storage chamber stores the food. That is, step S500 may be performed after step S300 or before step S100.
In one embodiment, the environmental status parameter includes at least one of temperature data, humidity data, carbon dioxide concentration data, and freshness.
Specifically, the types of the environmental status parameters are not unique, and the environmental status parameters corresponding to the environmental status parameters to be collected may be distinguished according to the inconsistency of the stored food types, in this embodiment, the environmental status parameters include the indoor temperature (i.e., temperature data) of the storage compartment, the indoor humidity (i.e., humidity data), the indoor carbon dioxide concentration (i.e., carbon dioxide concentration data), and the freshness status corresponding to the food. It can be understood that according to whether food is deteriorated or not, whether the food can be eaten or not, the freshness of the food can be classified into excellent, good, medium and low grade grades, and then the controller can send the status parameters to the display device for displaying, so as to remind a user to process the food in time when the freshness of the food is low.
And the corresponding environment state parameters of each type are acquired by different types of environment acquisition devices arranged in the storage chamber. Temperature data temperature collector gathers promptly, and humidity data gathers through humidity collector, and carbon dioxide concentration data then gathers through carbon dioxide concentration collector, and the new freshness is then gathered through the new freshness collector and is obtained. Further, in one embodiment, the temperature collector, the humidity collector and the carbon dioxide concentration collector are respectively a temperature sensor, a humidity sensor and a carbon dioxide concentration sensor, and the freshness collector is a food freshness module. The food freshness module is the integrative sensing module of temperature and humidity promptly, and this module can be to the gaseous perception that food process of rotting produced, synthesizes humiture data, the information of the new freshness grade of output representation food. It is to be appreciated that in one embodiment, the food freshness module can specifically sense the presence of a particular gas emitted by food spoilage using a MEMS gas sensor.
with continued reference to fig. 4, in one embodiment, step S700 includes step S710.
Step S710, sending an adjusting instruction to the environment adjusting device according to the environment state parameter and the best storage environment information obtained by analysis.
Specifically, in this embodiment, when the controller performs the operation of adjusting the storage environment of the storage compartment, it may further specifically combine the environment state parameter corresponding to the storage environment in the current state, and according to the relationship between the environment state parameter in the current state and the optimal storage environment information, correspondingly output different adjustment instructions to control the environment adjusting device to perform different adjustment operations, so that the storage environment of the final storage compartment is consistent with the environment corresponding to the optimal storage environment information.
Referring to fig. 5, in one embodiment, the environment state parameter includes temperature data, the optimal storage environment information includes a temperature threshold range, the environment adjusting device includes a refrigerator, and step S710 includes step S711 and step S712.
And step S711, when the temperature data is smaller than the minimum threshold value of the temperature threshold value range, sending a refrigeration stopping instruction to the refrigerator to control the refrigerator to stop refrigerating the storage compartment storing the food.
Specifically, when the temperature data is less than the minimum value of the temperature threshold range, it indicates that the temperature of the storage compartment under the current conditions is too low, and the temperature does not need to be further reduced. In one embodiment, for the case that there is only one storage compartment, the controller may directly send a stop command to the compressor of the refrigerator, and control the compressor of the refrigerator to stop operating so that the refrigerator stops the cooling operation. In other embodiments, when the number of the storage compartments is not unique, the controller sends a stop command to a valve on a pipeline corresponding to the storage compartment to be adjusted in the refrigerator, and controls a blowing pipeline corresponding to the storage compartment to stop blowing air, so as to stop the cooling operation of the corresponding storage compartment. It should be noted that in one embodiment, the temperature data is collected by a temperature sensor disposed in the storage compartment.
And step S712, when the temperature data is larger than the maximum threshold value of the temperature threshold value range, sending a refrigeration instruction to the refrigerator to control the refrigerator to refrigerate the storage room in which the food is stored.
Specifically, when the temperature data is greater than the maximum value of the temperature threshold range, it indicates that the temperature of the storage compartment under the current condition is too high, and the temperature reduction process needs to be performed on the storage compartment. Similar to the above refrigeration stopping, for different numbers of storage compartments, the specific control of the refrigerator to perform the refrigeration operation on the storage compartments is not unique, and the refrigeration operation can be realized by controlling the operation of the compressor or controlling the opening of the corresponding valve, which is not described herein again. Further, for the case that only one storage compartment is available, if the compressor is already in the running state at the moment, the controller sends an ascending frequency control command to the refrigeration device to control the refrigerator compressor to increase the running frequency so as to increase the refrigeration efficiency.
It should be noted that in one embodiment, the environment collection device collects the environmental state parameters and sends the collected environmental state parameters to the controller for analysis. Therefore, when the temperature is adjusted, if the temperature data is increased or decreased so that the temperature data is within the temperature threshold range, the controller will stop the corresponding adjusting operation. And when the temperature data is again lower than the minimum threshold value of the temperature threshold range or is again greater than the maximum threshold value of the temperature threshold range, the controller will again start the corresponding adjustment operation.
referring to fig. 6, in one embodiment, the environmental status parameter includes humidity data, the optimal storage environment information includes a humidity threshold range, the environment conditioning device includes a humidifier and a dehumidifier, and step S710 includes step S713 and step S714.
and step S713, when the humidity data is smaller than the minimum threshold value of the humidity threshold value range, sending an opening instruction to the humidifier to control the humidifier to be opened and operated.
Specifically, when the humidity data is smaller than the minimum value of the humidity threshold range, it is indicated that the moisture content of the storage chamber under the current condition is too low, and at this time, the controller sends an opening instruction to the humidifier to control the humidifier to operate so as to increase the humidity in the corresponding storage chamber. It should be noted that in one embodiment, the humidity data is collected by a humidity sensor disposed in the storage compartment.
And step S714, when the humidity data is larger than the maximum threshold value of the humidity threshold value range, sending an opening instruction to the dehumidifier to control the dehumidifier to open and operate.
specifically, when the humidity data is larger than the maximum value of the humidity threshold range, it is indicated that the moisture content of the storage chamber under the current condition is too high, and at this time, the controller sends an opening instruction to the dehumidifier to control the humidifier to operate so as to reduce the humidity in the corresponding storage chamber.
it should be noted that in one embodiment, the environment collection device collects the environmental state parameters and sends the collected environmental state parameters to the controller for analysis. Therefore, when the humidity is adjusted, if the humidity data is increased or decreased to make the humidity data within the humidity threshold range, the controller will stop the corresponding adjusting operation. And when the humidity data is again lower than the minimum threshold value of the humidity threshold range or is again greater than the maximum threshold value of the humidity threshold range, the controller will again start the corresponding adjustment operation.
Referring to fig. 7, in one embodiment, the environmental condition parameters include carbon dioxide concentration data, the optimal storage environment information includes a carbon dioxide concentration threshold range, the environmental conditioning device includes a carbon dioxide injector and a ventilator, and step S710 includes step S715 and step S716.
And step S715, when the carbon dioxide concentration data is smaller than the minimum threshold of the carbon dioxide concentration threshold range, sending a starting instruction to the carbon dioxide injection machine to control the carbon dioxide injection machine to start operation.
Specifically, when the carbon dioxide concentration data is smaller than the minimum value of the carbon dioxide concentration threshold range, it indicates that the carbon dioxide content of the storage compartment is too low under the current conditions, and the respiration of the stored food cannot be well inhibited. At the moment, the controller sends an opening instruction to the carbon dioxide injector to control the carbon dioxide injector to operate so as to increase the concentration of the carbon dioxide in the corresponding storage room. It should be noted that in one embodiment, the carbon dioxide concentration data is collected by a carbon dioxide sensor disposed in the storage compartment.
And step S716, when the carbon dioxide concentration data is larger than the maximum threshold value of the carbon dioxide concentration threshold value range, sending an opening instruction to the ventilator to control the ventilator to be opened and operated.
