[0056] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0058] In the description of this application, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0059] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.
[0060] In some cases, when using existing refrigerators to ripen fruits and vegetables using high temperatures and ethylene, there's a problem of all fruits ripening prematurely, affecting their quality and resulting in poor taste. Furthermore, if ripening is achieved in the refrigerator using a combination of appropriate temperature and light, different types of fruits and vegetables require different temperature and light conditions. Also, due to the accelerated ripening process, users cannot accurately control the ripening time, potentially missing the optimal consumption period and even causing waste.
[0061] Red light is crucial for the development of photosynthetic apparatus, promoting plant growth and development by increasing the net photosynthetic rate. Blue light controls chloroplast development, stomatal opening, and branch growth. Different light energies produce different effects; certain light energies can induce chlorophyll decomposition, increase the synthesis of related pigments, and induce the appearance of ethylene peaks, thus achieving a ripening effect. Furthermore, due to the rectilinear propagation of light, only the fruits and vegetables directly exposed to the light will ripen. Different fruits require different light for ripening; for example, red light is most effective for ripening small mangoes, avocados, and kiwifruit, while blue light is more effective for ripening Guifei mangoes, red-skinned longans, and dragon fruit. The respiration of fruits and vegetables is positively correlated with temperature. Within a certain range, increasing temperature can increase the respiration and transpiration rates of fruits. The higher the temperature, the earlier and shorter the duration of the respiration climacteric in fruits, resulting in faster ripening.
[0062] Based on the above, this application proposes a refrigerator control method, controller, refrigerator, and storage medium, aiming to achieve the identification of fruit and vegetable varieties and precise ripening.
[0063] The various embodiments of the refrigerator of this application will be further described below with reference to the accompanying drawings.
[0064] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a refrigerator provided in one embodiment of this application.
[0065] In one embodiment, the compartment 110 of the refrigerator 100 is provided with a light source device 120 and a spectral imaging module 130.
[0066] In one embodiment, the light source device 120 includes multiple light source units, with different light source units 120 distributed at different locations in the compartment 110, and each light source unit 120 including multiple light sources of different wavelengths.
[0067] In one embodiment, the light source selection array arrangement selects LED light sources of 400-500nm, 500-600nm, 600-700nm, 700-800nm, 800-900nm, and 900-1000nm, or light sources with narrower wavelengths and a greater number of them. Six light sources form one unit, but the 400-500nm and 600-700nm light sources are controlled separately from the other spectral light sources. The total number of light source units in the entire light source device 120 is greater than or equal to five.
[0068] like Figure 2 As shown, Figure 2 This is a structural diagram of the light source of a refrigerator provided in one embodiment of this application.
[0069] In one embodiment, the light source unit can be positioned in five areas, emitting either red or blue light. These are four corner areas and one central area. When food is placed in a corner area, the corresponding light in that area will illuminate the food. The light source can automatically adjust the illumination direction based on the position and shape of the food to achieve the best illumination effect. When the food is moved out of the illumination area, the control unit will automatically turn off the corresponding light source to save energy.
[0070] Based on the hardware structure of the refrigerator in the above embodiments, the following presents various embodiments of the refrigerator control method of this application.
[0071] like Figure 3 As shown, Figure 3 This is a flowchart of a refrigerator control method provided in one embodiment of this application; the refrigerator control method may include, but is not limited to, steps S310, S320, S330, and S340.
[0072] Step S310: Acquire image and spectral information of the food ingredients through the spectral imaging module;
[0073] Step S320: Determine the type of food ingredient based on the image information, and determine the ripeness of the food ingredient based on the spectral information;
[0074] Step S330: Control the chamber to open the target mode corresponding to the maturity of the ingredients according to the maturity of the ingredients. The target mode includes ripening mode or storage mode.
[0075] Step S340: In target mode, adjust the storage environment parameters of the compartment according to the type and maturity of the ingredients.
[0076] In one embodiment, when a spectral imaging module is installed in the refrigerator compartment, this embodiment acquires image and spectral information of the food through the spectral imaging module. Since the image and spectral information of different types of food are different, the type of food is determined based on the image information, and the maturity of the food is determined based on the spectral information, thereby improving the accuracy of judging the type and maturity of the food. The maturity mode required for each type of food is not completely consistent, so the compartment is controlled to open a target mode corresponding to the maturity of the food according to the maturity of the food. The target mode includes a ripening mode or a storage mode. When it is determined that the compartment is in ripening mode or storage mode, the storage environment parameters of the compartment are adjusted according to the type and maturity of the food, thereby realizing the identification of fruit and vegetable types and precise ripening.
[0077] It should be noted that during the ripening process, fruits and vegetables undergo changes in respiration rate, cell membrane permeability, cell wall composition, starch content, and the activity of hydrolytic enzymes such as amylase and polygalacturonase. These changes ultimately manifest as the firmness of the fruits and vegetables. Fruit firmness refers to the flesh's resistance to pressure; the greater the resistance to pressure, the firmer the fruit. Generally, as the fruit matures, its firmness gradually decreases. Therefore, the firmness of fruits and vegetables can be used to determine their ripeness.
[0078] like Figure 4 As shown, Figure 4 This is a flowchart of a refrigerator control method provided in another embodiment of this application; regarding the acquisition of image information and spectral information of food through the spectral imaging module in step S310 above, it may include, but is not limited to, steps S410, S420 and S430.
[0079] Step S410: Receive spectral detection command;
[0080] Step S420: Activate the light source device to irradiate the food according to the spectral detection command, and receive the light signal reflected by the food through the spectral imaging module;
[0081] Step S430: Generate image information and spectral information of the food ingredients based on the light signal using the spectral imaging module.
[0082] In one embodiment, the system first receives a spectral detection command through a user interface or an automatic detection program. The refrigerator controller activates the light source device to irradiate the food according to the spectral detection command. The light signal reflected by the food is received by the spectral imaging module, which converts the received light signal into an electrical signal. Then, the system software processes the signal to generate image information and spectral information of the food.
[0083] It should be noted that, in this embodiment of the application, a refrigerator door switch sensor can be added to the refrigerator door. When the refrigerator door switch sensor detects that the refrigerator door is open, the refrigerator control system generates a spectral detection command, and the automatic detection program receives the spectral detection command.
[0084] In addition, it is understood that the type of refrigerator door switch sensor can be a mechanical switch, a reed switch, a capacitive sensor, an inductive sensor, an ultrasonic sensor, or other types of refrigerator door switch sensors. This application does not limit the specific type of refrigerator door switch sensor.
[0085] It should be noted that, in this embodiment of the application, a control panel can be installed at the refrigerator door. The user can select to send a spectral detection command through the control panel. When the user selects to send a spectral detection command, the refrigerator controller receives the spectral detection command.
[0086] In one embodiment, activating the light source device to irradiate the food according to the spectral detection command includes activating the light source device to irradiate the food with a first power according to the spectral detection command, wherein the first power is less than a preset power.
[0087] It should be noted that when the user activates the spectral detection function at a fixed time, the light source device irradiates the food at the first power, that is, the light source device irradiates the food at the first power with wavelengths of 400-500nm and 600-700nm. After receiving the information, the spectral imaging module identifies the type of food and judges the state of the food.
[0088] It should be noted that the aforementioned preset power can be set by the user or the system. The user or system can set the specific value of the preset power according to their own needs; this embodiment does not specifically limit the value of the preset power. This allows the preset power to be more reasonable, not only better ensuring the normal operation of the system but also making the irradiation more accurate.
[0089] like Figure 5 As shown, Figure 5 This is a flowchart of a refrigerator control method provided in another embodiment of this application; regarding the determination of the type of food based on image information in step S320 above, it may include, but is not limited to, steps S510 and S520.
[0090] Step S510: Extract the target texture information of the food ingredients from the image information;
[0091] Step S520: Input the target texture information into the preset type recognition model, and output the target food type information corresponding to the target texture information through the type recognition model. The type recognition model stores the correspondence between texture information and food type information.
[0092] It should be noted that in the process of extracting the target texture information of food from image information, since texture information is an important feature of the surface structure of food, texture information can be used to identify the type of food. By inputting the target texture information into a preset type recognition model, the type recognition model analyzes and calculates the information, and then outputs the target food type information corresponding to the target texture information.
[0093] It should be noted that the preset species recognition model can be a species recognition model obtained through pre-training, a species recognition model obtained by training the model on a large-scale dataset, or a species recognition model obtained by fine-tuning on a target dataset. This application embodiment does not impose specific restrictions on the method of obtaining the preset species recognition model.
[0094] like Figure 6 As shown, Figure 6 This is a flowchart of a refrigerator control method provided in another embodiment of this application; regarding the determination of the food's ripeness based on spectral information in step S320 above, it may include, but is not limited to, steps S610 and S620.
[0095] Step S610: Input the spectral information into the preset hardness recognition model, and output the target food hardness information corresponding to the spectral information through the hardness recognition model. The hardness recognition model stores the correspondence between the spectral information and the food hardness information.
[0096] Step S620: Determine the ripeness of the ingredient based on the hardness information of the target ingredient.
[0097] It should be noted that in the process of determining the ripeness of food from spectral information, since spectral information is an important feature for determining the hardness of food, spectral information can be used to identify the ripeness of food. By inputting the spectral information into a preset hardness recognition model, the model analyzes and calculates the information, outputs the target food hardness information corresponding to the spectral information, and finally determines the ripeness of food based on the target food hardness information.
[0098] It should be noted that the preset hardness recognition model can be a hardness recognition model obtained through pre-training, a hardness recognition model obtained by training the model on a large-scale dataset, or a hardness recognition model obtained by fine-tuning on a target dataset. This application does not impose specific restrictions on the method of obtaining the preset hardness recognition model.
[0099] In one embodiment, controlling the chamber to open a target mode corresponding to the ripeness of the ingredients, based on the ripeness of the ingredients, includes at least one of the following:
[0100] (i) When the maturity indicator of the ingredients is that the ingredients are not mature, the control chamber will activate the ripening mode.
[0101] (ii) When the food maturity indicator shows that the food is mature, the control compartment will activate the storage mode.
[0102] In one embodiment, the system controls the compartment to open different target modes according to the maturity of the ingredients. When the maturity of the ingredients indicates that the ingredients are not mature, the compartment opens the ripening mode to accelerate the ripening process of the ingredients; when the maturity of the ingredients indicates that the ingredients are mature, the compartment opens the storage mode to maintain the freshness and taste of the ingredients.
[0103] In one embodiment, when the spectral imaging module detects that the food is cooked, it reminds the user to eat it and sends a signal to the compartment to activate the storage mode. The method of reminding the user to eat it can be through voice reminder, screen display reminder, or app reminder.
[0104] In one embodiment, adjusting the storage environment parameters of the compartment according to the type and maturity of the ingredients includes at least one of the following:
[0105] (i) When the target mode is ripening mode, adjust the air and light parameters of the chamber according to the type and maturity of the ingredients.
[0106] (ii) When the target mode is storage mode, adjust the air parameters of the compartment according to the type and maturity of the ingredients.
[0107] In one embodiment, when the target mode is ripening mode, the system adjusts the air parameters (such as temperature and humidity) and light parameters of the compartment according to the type and maturity of the food to promote the ripening process. When the target mode is storage mode, the system also adjusts the air parameters of the compartment according to the type and maturity of the food, but the purpose is to maintain the current ripeness of the food and prevent over-ripening or spoilage.
[0108] like Figure 7 As shown, Figure 7This is a flowchart of a refrigerator control method provided in another embodiment of this application; it may include, but is not limited to, steps S710, S720 and S730.
[0109] Step S710: Determine the location information of the ingredients based on the image information;
[0110] Step S720: In the ripening mode, determine the target light source unit corresponding to the location information based on the location information;
[0111] Step S730: Control the illumination wavelength of the target light source unit according to the type of food.
[0112] In one embodiment, the system uses image recognition technology to extract the location information of the ingredients from the image information captured by the camera. In the ripening mode, the system determines the target light source unit corresponding to the location information of the ingredients. Thus, the system can accurately control the activated light source to illuminate the area of the corresponding ingredient location. Since different types of ingredients require light of different wavelengths to promote ripening, controlling the light wavelength of the target light source unit according to the type of ingredients can improve the rationality of the ripening process.
[0113] like Figure 8 As shown, Figure 8 This is a flowchart of a refrigerator control method provided in another embodiment of this application; regarding the above step S730, it may include, but is not limited to, steps S810 and S820.
[0114] Step S810: Determine the target light wavelength for ripening ingredients based on the type of ingredients;
[0115] Step S820: Turn on the target light source corresponding to the target light wavelength so that the target light source irradiates the food at the target light wavelength.
[0116] In one embodiment, the type of food is identified, and the system determines the target light wavelength for ripening the food based on the type. Since different types of food require different wavelengths of light to promote ripening, the system activates a target light source corresponding to the target light wavelength, so that the target light source irradiates the food at the target light wavelength. The system can automatically adjust the light parameters according to changes in the type and ripeness of the food. This intelligent control can improve the efficiency and success rate of food ripening.
[0117] In one embodiment, the target light source is controlled to irradiate the food with a second power, wherein the second power is greater than or equal to a preset power.
[0118] It should be noted that after determining the target light wavelength for ripening the food based on the type of food, the light source device turns on the target light source corresponding to the target light wavelength and controls the target light source to irradiate the food in the corresponding compartment with the second power.
[0119] In one embodiment, when the food maturity level indicates that the food is mature and edible, a first reminder message is pushed to the user, wherein the first reminder message is used to remind the user to eat the food; when the food maturity level indicates that the food is overcooked, a second reminder message is pushed to the user, wherein the second reminder message is used to remind the user to eat the food within a preset time or to remind the user not to eat the food.
[0120] In one embodiment, when the system detects that the food's maturity indicates it is mature and suitable for consumption, it automatically generates and pushes a first reminder message to the user's device. This first reminder message notifies the user that the food has reached its optimal state for consumption, thus reminding the user to eat it promptly to avoid missing the best time to enjoy it. This reminder message can be delivered in various ways, including but not limited to mobile application push notifications, SMS reminders, voice assistant announcements, or smart device displays. When the system detects that the food's maturity indicates it is overripe and unsuitable for consumption, it generates and pushes a second reminder message, reminding the user to consume the food within a preset time or indicating that the food may have exceeded its edible stage, suggesting stopping consumption or taking necessary measures (such as discarding or using it for other non-edible purposes). This second reminder message may include a specific description of the food's state and may include further processing suggestions to ensure the user avoids consuming expired or spoiled food.
[0121] In one embodiment, users can view the storage status and maturity of food in real time via the refrigerator's touchscreen or an app, as well as remotely adjust the refrigerator's settings. The system records the storage data of the food and the adjustment history of environmental parameters, providing a basis for subsequent data analysis and system optimization.
[0122] In one embodiment, regarding the aforementioned first and second reminder messages, the system can choose a fixed time or a user-defined time to remind the user to eat food, remind the user to eat food within a preset time, or suggest that the user not eat food through the refrigerator controller. The system can also remind the user to eat food, remind the user to eat food within a preset time, or suggest that the user not eat food through text or other means on the refrigerator's control panel screen. The system can also remind the user to eat food, remind the user to eat food within a preset time, or suggest that the user not eat food through SMS or other means via an APP. This application embodiment does not specifically limit the manner of the first and second reminder messages.
[0123] like Figure 9As shown, Figure 9 This is an overall flowchart of a refrigerator control method provided in one embodiment of this application. It may include, but is not limited to, steps S9001-S9011.
[0124] Step S9001: Add the ingredients;
[0125] Step S9002: The spectral imaging module begins operation;
[0126] Step S9003: Turn on the light source;
[0127] Step S9004, Category Information;
[0128] Step S9005, Location Information;
[0129] Step S9006, maturity information;
[0130] Step S9007, not yet mature;
[0131] Step S9008: Turn on the corresponding light source at the corresponding location and adjust the temperature, humidity and other conditions to be suitable.
[0132] Step S9009: Remind the user of maturity level;
[0133] Step S9010: Storage mode, adjust corresponding temperature, humidity and other conditions;
[0134] Step S9011: Remind users to consume as soon as possible / It is not recommended to consume.
[0135] In one embodiment, after the user places food into the refrigerator, the refrigerator's spectral imaging module turns on its light source. The refrigerator acquires image information, spectral information, and location information of the food through the spectral imaging module. Based on the image information, it determines the type of food, and based on the spectral information, it determines the ripeness of the food. Based on the type and ripeness information, the system obtains the ripeness status of the food.
