Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances. More specifically, it relates to a control method for a refrigerator and a refrigerator. Background Art

[0002] Vacuum drawers are usually provided in refrigerators. For a vacuum drawer, the air in the vacuum drawer can be evacuated to extend the freshness preservation time of the food in the vacuum drawer.

[0003] Currently, after the vacuum drawer is opened and then closed, the refrigerator evacuates the air in the vacuum drawer according to preset parameters, so that the pressure value in the vacuum drawer reaches the pressure value corresponding to the parameters.

[0004] However, the method of evacuating air from the vacuum drawer with fixed parameters has poor pertinence and may result in poor freshness preservation effect of the vacuum drawer. Summary of the Invention

[0005] The embodiments of the present application provide a control method for a refrigerator and a refrigerator, which can improve the freshness preservation effect of the vacuum drawer, thereby enhancing the user experience.

[0006] In a first aspect, the embodiments of the present application provide a control method for a refrigerator, which is applied to a refrigerator and includes:

[0007] When it is detected that the door of the vacuum drawer in the refrigerator is switched from the open state to the closed state, obtain a control parameter, where the control parameter is obtained by processing the storage environment parameters of the target food in the vacuum drawer through a food freshness preservation environment regulation model;

[0008] According to the control parameter, control the operation of the compressor and the vacuum pumping device in the refrigerator, so that the environment in the vacuum drawer reaches the storage environment corresponding to the storage environment parameters.

[0009] In the present application, after the door of the vacuum drawer is opened, the environment in the vacuum drawer will change. For example, both the pressure and the temperature will change. Therefore, it is necessary to adjust the environment of the vacuum drawer. The corresponding control parameter can be determined according to the suitable storage environment corresponding to the target food in the vacuum drawer, and then the compressor and the vacuum pumping device can be controlled through the control parameter, so that the environment in the vacuum drawer reaches the environment suitable for storing the target food, realizing the adaptive adjustment of the environment in the vacuum drawer, improving the freshness preservation effect of the vacuum drawer, and thus enhancing the user experience.

[0010] In some embodiments of the present application, the food freshness preservation environment regulation model is in the refrigerator, and when it is detected that the door of the vacuum drawer is switched from the open state to the closed state, obtaining the control parameter includes:

[0011] When it is detected that the door of the vacuum drawer is switched from the open state to the closed state, obtain the ingredient information of multiple ingredients currently stored in the vacuum drawer;

[0012] Determine the target ingredient according to the preset ingredient importance sorting principle and the ingredient information;

[0013] Obtain the storage environment parameters corresponding to the target ingredient;

[0014] Input the storage environment parameters into the ingredient freshness preservation environment regulation model to obtain the control parameters.

[0015] In this application, by setting the ingredient freshness preservation environment regulation model in the refrigerator, the refrigerator can autonomously determine the corresponding control parameters according to the changes of the ingredients.

[0016] In some embodiments of this application, the ingredient freshness preservation environment regulation model is in the cloud device. When it is detected that the door of the vacuum drawer is switched from the open state to the closed state, obtaining the control parameters includes:

[0017] When it is detected that the door of the vacuum drawer is switched from the open state to the closed state, receive the control parameters sent by the cloud device. The control parameters are determined by the cloud device according to the storage environment parameters of the target ingredient among the multiple ingredients currently stored in the vacuum drawer, and the storage environment parameters are input into the ingredient freshness preservation environment regulation model, and are obtained through the ingredient freshness preservation environment regulation model.

[0018] In this application, by setting the ingredient freshness preservation environment regulation model in the cloud device, the resource occupancy of the refrigerator controller can be reduced, and the speed of determining the control parameters can be improved to a certain extent, realizing that the refrigerator adaptively adjusts the environment of the vacuum drawer according to the ingredients stored in the vacuum drawer, and can improve the freshness preservation effect of the vacuum drawer.

[0019] In some embodiments of this application, the control parameters are obtained by processing the storage environment parameters and the pressure change parameters of the target ingredient in the vacuum drawer through the ingredient freshness preservation environment regulation model. The pressure change parameters are obtained by performing a vacuum pumping operation on the vacuum drawer in advance after the vacuum drawer is closed.

[0020] In this application, by performing a vacuum pumping operation on the vacuum drawer in advance, the number of ingredients in the refrigerator can be characterized by the pressure change parameters obtained by the pre-vacuum pumping operation, so that the accuracy of the control parameters determined according to the storage environment parameters and the pressure change parameters is higher.

[0021] In some embodiments of this application, the method further includes:

[0022] When it is detected that the door of the vacuum drawer is switched from the open state to the closed state, control the operation of the vacuum pumping device to reduce the pressure in the vacuum drawer to the target pressure value, and obtain the time interval during which the pressure value drops to the target pressure value, and determine the time interval as the pressure change parameter.

[0023] In the present application, the time interval for the pressure to drop to the target pressure value can reflect, from the side, the operating time of the vacuum pumping device and the situation of the pressure value drop in the vacuum drawer, making the control parameters corresponding to the vacuum pumping device obtained by the food preservation environment regulation model based on the storage environment parameters and the pressure change parameters more accurate.

[0024] In some embodiments of the present application, the obtaining the time interval during which the pressure value drops to the target pressure value and determining the time interval as the pressure change parameter includes:

[0025] Obtain a first signal, which is generated when the pressure in the vacuum drawer is the pressure value of the external environment and the pressure switch in the vacuum drawer is switched from the off state to the on state;

[0026] Obtain a second signal, which is generated when the pressure in the vacuum drawer is the target pressure value and the pressure switch is switched from the on state to the off state;

[0027] Determine the time interval between receiving the first signal and receiving the second signal, and determine the time interval as the pressure change parameter.

[0028] In the present application, by setting a pressure switch in the vacuum drawer, the acquisition of the pressure change parameter can be realized. Compared with setting a pressure sensor, the cost of the pressure switch is lower, and the cost of the refrigerator can be reduced.

[0029] In some embodiments of the present application, the method further includes:

[0030] When it is detected that the door of the vacuum drawer is switched from the open state to the closed state, obtain the food ingredients that the user puts into or takes out from the vacuum drawer;

[0031] Update the information of the food ingredients stored in the vacuum drawer according to the food ingredients.

[0032] In the present application, by updating the information of the food ingredients, the stored information corresponds to the food ingredients stored in the vacuum drawer, so as to facilitate subsequent targeted adjustment of the environment in the vacuum drawer.

[0033] In some embodiments of the present application, the control parameters include the start-up temperature and shutdown temperature of the compressor, and the target working duration of the vacuum pumping device.

[0034] In the present application, the temperature inside the vacuum drawer can be adjusted by the startup temperature and the shutdown temperature, and by determining the target working duration of the vacuum pumping device, the operation of the vacuum pumping device can be controlled so that the pressure value inside the vacuum drawer reaches a pressure value suitable for storing the target food ingredients.

[0035] In some embodiments of the present application, controlling the operation of the compressor and the vacuum pumping device inside the refrigerator according to the control parameters includes:

[0036] When the temperature inside the vacuum drawer is greater than or equal to the startup temperature, control the compressor to operate until the temperature inside the vacuum drawer is less than or equal to the shutdown temperature, and then control the compressor to stop operating;

[0037] Control the vacuum pumping device to operate for the target working duration.

[0038] In the present application, by controlling the compressor and the vacuum pumping device, the environment inside the vacuum drawer is made to reach an environment suitable for storing the target food ingredients, thereby improving the freshness preservation effect of the target food ingredients.

[0039] In a second aspect, the present application provides a refrigerator, including:

[0040] A box body, configured with at least one storage compartment;

[0046] According to the control parameters, control the operation of the compressor and the vacuum pumping device so that the environment inside the vacuum drawer reaches the storage environment corresponding to the storage environment parameters.

[0047] In a third aspect, the present application provides a computer-readable storage medium, in which computer-executable instructions are stored, and when the computer-executable instructions are executed by a computer, they are used to implement the method described in the first aspect.

[0063] To make the objectives, implementation manners and advantages of this application clearer, the following will clearly and completely describe the exemplary implementation manners of this application with reference to the accompanying drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only a part rather than all of the embodiments of this application.

[0064] It should be noted that the brief description of the terms in this application is only for facilitating the understanding of the subsequent described implementation manners, rather than intending to limit the implementation manners of this application. Unless otherwise specified, these terms should be understood according to their ordinary and common meanings.

[0065] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclusively include. For example, a product or device including a series of components does not necessarily have to be limited to those components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0066] By evacuating the air in the vacuum drawer (i.e., performing a vacuum operation), the oxygen concentration can be reduced, the oxidation rate of the food ingredients can be slowed down, and the vacuum environment can prevent the evaporation of food moisture. Therefore, compared with the ordinary storage compartments in the refrigerator, the vacuum drawer has a better fresh-keeping effect on the food ingredients.

[0067] When the vacuum drawer is opened, the air pressure value inside the vacuum drawer will return to the same air pressure as the external environment. Therefore, after the vacuum drawer is closed, it is necessary to evacuate the vacuum drawer. Currently, after the vacuum drawer is closed, the evacuation of the vacuum drawer is controlled by pre-stored parameters so that the pressure value inside the vacuum drawer reaches a pre-set pressure value.

[0068] However, controlling the evacuation of the vacuum drawer by pre-stored parameters cannot be adjusted according to the conditions of the ingredients stored in the vacuum drawer, resulting in poor pertinence and possibly poor freshness preservation effect of the vacuum drawer.

[0069] Based on this, the present application provides a control method and a refrigerator for a refrigerator. When it is detected that the door of the vacuum drawer is switched from the open state to the closed state, the compressor and the evacuation device can be controlled to operate according to the obtained control parameters, so that the storage environment in the vacuum drawer reaches the environment suitable for the ingredients. Among them, the control parameters are obtained based on the storage environment required by the ingredients in the vacuum drawer. In this way, when adjusting the storage environment in the vacuum drawer, the environment of the vacuum drawer can be adjusted according to the ingredients currently stored in the refrigerator, which can effectively improve the freshness preservation effect of the vacuum drawer.

[0070] The technical solutions of the present application will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other or exist independently. For the same or similar concepts or processes, they may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0071] First, the structure of the refrigerator provided by some embodiments of the present application will be described.

[0072] In a possible implementation, Figure 1 As a schematic diagram of a refrigerator according to some embodiments, as Figure 1 shown, the refrigerator 10 includes a cabinet 101.

[0073] The refrigerator 10 further includes a door body 102, and the door body 102 is connected to the cabinet 101.

[0074] The refrigerator 10 further includes at least one storage compartment and a vacuum drawer, and the storage compartment and the vacuum drawer are both arranged in the cabinet 101.

[0075] In a possible implementation, the storage compartment may include a refrigerating compartment and / or a freezing compartment, etc.

[0076] In a possible implementation, the refrigerator 10 further includes a controller and a compressor. The controller and the compressor are both arranged in the cabinet.

[0077] In the embodiments of the present application, the controller may be a Micro Controller Unit (MCU) or other types of controllers, and the embodiments of the present application do not specifically limit the controller.

[0078] The internal structure of the refrigerator 10 can be seen in Figure 2 shown, Figure 2Schematic diagram of the internal structure of a refrigerator according to some embodiments.

[0079] As Figure 2 shown, the refrigerator 10 may include a refrigerating chamber 21 and a freezing chamber 22, wherein a vacuum drawer 23 is disposed in the refrigerating chamber 21.

[0080] The embodiments of the present application are only described by taking the setting of the Figure 2 shown vacuum drawer as an example, and do not constitute any limitation.

[0081] Next, during the operation of the refrigerator, the control method of the refrigerator by the controller will be described. For details, please refer to Figure 3 shown. Figure 3 Schematic diagram of the process of a control method of a refrigerator according to some embodiments Figure 1 .

[0082] Figure 3 As shown, the control method of the refrigerator may include the following steps:

[0083] S301. When it is detected that the door of the vacuum drawer in the refrigerator is switched from the open state to the closed state, obtain control parameters, where the control parameters are obtained by processing the storage environment parameters of the target food in the vacuum drawer through a food preservation environment regulation model.

[0084] The target food may be one or several foods determined from the foods stored in the vacuum drawer according to a preset selection rule. The embodiments of the present application do not limit the target food.

[0085] The food preservation environment regulation model may be a pre-trained model that can output corresponding control parameters according to the input storage environment parameters.

[0086] Exemplarily, the control parameters include the start-up temperature and shutdown temperature of the compressor, and the target working duration of the vacuum pumping device.

[0087] Among them, the start-up temperature means that when the temperature in the vacuum drawer is greater than or equal to the start-up temperature, control the compressor to start running. The shutdown temperature means that when the temperature in the vacuum drawer is less than the start-up temperature, control the compressor to stop running.

[0088] In this way, the temperature in the vacuum drawer can be adjusted through the start-up temperature and shutdown temperature, and by determining the target working duration of the vacuum pumping device, the operation of the vacuum pumping device can be controlled so that the pressure value in the vacuum drawer reaches the pressure value suitable for storing the target food.

[0089] S302. According to the control parameters, control the compressor and the vacuum pumping device in the refrigerator to run so that the environment in the vacuum drawer reaches the storage environment corresponding to the storage environment parameters.

[0090] In the present application, controlling the operation of the compressor and the vacuum pumping device by controlling parameters may include: when the temperature inside the vacuum drawer is greater than or equal to the startup temperature, controlling the compressor to operate until the temperature inside the vacuum drawer is less than or equal to the shutdown temperature, and then controlling the compressor to stop operating. And controlling the target operating duration of the vacuum pumping device.

[0091] In this way, by controlling the compressor and the vacuum pumping device, the environment inside the vacuum drawer is made to reach an environment suitable for storing the target food ingredients, thereby enhancing the freshness preservation effect of the target food ingredients.

[0092] The control method provided by the embodiment of the present application, after the door of the vacuum drawer is opened, can determine the corresponding control parameters according to the target food ingredients inside the vacuum drawer and the pressure change parameters of the vacuum drawer, so as to control the compressor and the vacuum pumping device through the control parameters, so that the environment inside the vacuum drawer reaches an environment suitable for storing the target food ingredients, realizing an adaptive adjustment of the environment inside the vacuum drawer, enhancing the freshness preservation effect of the vacuum drawer, and thus enhancing the user experience.

[0093] In the present application, the setting positions of the food ingredient freshness preservation environment regulation model may include the following two possible implementations:

[0094] In one possible implementation, the food ingredient freshness preservation environment regulation model is set inside the refrigerator.

[0095] In this possible implementation, the method for obtaining the control parameters may include: when it is detected that the door of the vacuum drawer is switched from the open state to the closed state, obtaining the food ingredient information of multiple food ingredients stored inside the current vacuum drawer; determining the target food ingredients according to the preset food ingredient importance ranking principle and the food ingredient information; obtaining the storage environment parameters corresponding to the target food ingredients; and inputting the storage environment parameters into the food ingredient freshness preservation environment regulation model to obtain the control parameters.

[0096] In this way, by setting the food ingredient freshness preservation environment regulation model inside the refrigerator, the refrigerator can directly generate control parameters according to the situation of the food ingredients inside the vacuum drawer and perform control.

[0097] In another possible implementation, the food ingredient freshness preservation environment regulation model is set inside the cloud device.

[0098] In this possible implementation, the method for obtaining the control parameters may include: when it is detected that the door of the vacuum drawer is switched from the open state to the closed state, receiving the control parameters sent by the cloud device, where the control parameters are obtained by the cloud device determining the storage environment parameters according to the target food ingredients among the multiple food ingredients stored inside the current vacuum drawer, and inputting the storage environment parameters into the food ingredient freshness preservation environment regulation model and obtaining them through the food ingredient freshness preservation environment regulation model.

[0099] In this way, by setting the food freshness preservation environment regulation model in the cloud device, the situation where the food freshness preservation environment regulation model occupies a large amount of resources of the refrigerator controller can be reduced.

[0100] In the present application, the generation of the control parameters can also be based on the pressure change parameters, that is, the control parameters are obtained by processing the storage environment parameters and the pressure change parameters of the target food in the vacuum drawer through the food freshness preservation environment regulation model, and the pressure change parameters are obtained by performing a vacuum pumping operation on the vacuum drawer in advance after the vacuum drawer is closed.

[0101] Considering that even if the storage environment parameters are the same, for example, the recommended storage temperature of salmon is -0.5 degrees Celsius and the vacuum degree is 0.75 standard atmospheric pressure. Under different amounts of food, if each core module (such as the refrigeration device and the vacuum motor) adopts the same working method (such as the starting point is 3 degrees Celsius, the shutdown point is -1 degree Celsius, and the vacuum motor works for 375 seconds), the environment inside the vacuum drawer may be different in the end. Therefore, the food freshness preservation environment regulation model will comprehensively consider the amount of food and adjust the working plan of the core module. For example, when salmon occupies 2 / 3 of the drawer volume, the time required to achieve 0.75 atmospheric pressure is shorter than when it occupies 1 / 4 of the volume. Therefore, the pressure change parameters are obtained in advance to predict the amount of food in the vacuum drawer.

[0102] In this way, by performing a vacuum pumping operation on the vacuum drawer in advance, the amount of food in the refrigerator can be characterized by the pressure change parameters obtained from the pre-vacuum pumping operation, so that the accuracy of the control parameters determined according to the storage environment parameters and the pressure change parameters is higher.

[0103] Combined with the above, the control parameters are obtained based on the storage environment parameters and the pressure change parameters. Next, the cases where the food freshness preservation environment regulation model is set in the refrigerator and the cloud device will be described separately.

[0104] When the food freshness preservation environment regulation model is set in the refrigerator, the control method can be referred to Figure 4 as shown Figure 4 is a schematic flow chart of a control method of a refrigerator according to some embodiments Figure 2 .

[0105] As Figure 4 shown, the control method of the refrigerator includes the following steps:

[0106] S401. When it is detected that the door of the vacuum drawer is switched from the open state to the closed state, obtain the food information of multiple foods stored in the current vacuum drawer.

[0107] When it is detected that the door of the vacuum drawer is switched from the open state to the closed state, obtain the ingredients that the user puts into or takes out from the vacuum drawer; update the information of the ingredients stored in the vacuum drawer according to the ingredients.

[0108] The user putting ingredients into the vacuum drawer can include the following two possible implementations:

[0109] In one possible implementation, when the user puts ingredients into the vacuum drawer, the user can input the information of the ingredients put in through the display screen of the refrigerator. After the controller receives the information of the ingredients input by the user, it updates the information of the ingredients stored in the vacuum drawer to obtain new ingredient information.

[0110] In another possible implementation, when the user puts ingredients into the vacuum drawer, the user can input the information of the ingredients put in through the application program of the terminal device. The application program can interact with the controller of the refrigerator and send the information of the ingredients put in to the controller. After the controller receives the information of the ingredients, it updates the information of the ingredients stored in the vacuum drawer to obtain new ingredient information.

[0111] The user taking ingredients out from the vacuum drawer can include the following two possible implementations:

[0112] In one possible implementation, when the user takes ingredients out from the vacuum drawer, the user can input the information of the ingredients taken out through the display screen of the refrigerator. After the controller receives the information of the ingredients input by the user, it updates the information of the ingredients stored in the vacuum drawer, deletes the information of the ingredients taken out, and obtains new ingredient information.

[0113] In another possible implementation, when the user takes ingredients out from the vacuum drawer, the user can input the information of the ingredients taken out through the application program of the terminal device. The application program can interact with the controller of the refrigerator and send the information of the ingredients taken out to the controller. After the controller receives the information of the ingredients, it updates the information of the ingredients stored in the vacuum drawer, deletes the information of the ingredients taken out, and obtains new ingredient information.

[0114] In this way, by updating the information of the ingredients, the stored information corresponds to the ingredients stored in the vacuum drawer, so as to facilitate subsequent targeted adjustment of the environment in the vacuum drawer.

[0115] S402. Determine the target ingredients according to the preset ingredient importance sorting principle and ingredient information.

[0116] The principle for sorting the importance of food ingredients can be based on the price of the food ingredients, or based on the freshness preservation duration of the food ingredients, or user-defined. The embodiments of the present application do not make specific limitations on the principle for sorting the importance of food ingredients.

[0117] For example, the user can customize the principle for sorting the importance of food ingredients through the display screen of the refrigerator or the application program of the terminal device.

[0118] Exemplarily, according to the preset principle for sorting the importance of food ingredients and the food ingredient information, to determine the target food ingredient, all the food ingredients stored in the vacuum drawer can be sorted according to the principle for sorting the importance of food ingredients based on the food ingredient information, and the top N food ingredients in terms of importance are determined as the target food ingredients. Wherein, N is an integer greater than or equal to 1.

[0119] Taking the principle for sorting the importance of food ingredients based on the price of the food ingredients as an example, according to the preset principle for sorting the importance of food ingredients and the food ingredient information, to determine the target food ingredient, it can be: all the food ingredients stored in the vacuum drawer are sorted according to the price, and the food ingredient ranked first is determined as the target food ingredient. For example, the food ingredients stored in the vacuum drawer include spinach, Chinese cabbage, and salmon, and among them, the price of salmon is the highest, then salmon can be determined as the target food ingredient.

[0120] S403. Obtain the storage environment parameters corresponding to the target food ingredient, and obtain the pressure change parameter.

[0121] In the controller, the corresponding relationships between multiple food ingredients and storage environment parameters can be pre-stored. In this way, after the target food ingredient is determined, the storage environment parameters corresponding to the target food ingredient can be determined in the pre-stored corresponding relationships. For example, when the target food ingredient is salmon, the storage environment parameters corresponding to salmon can be determined.

[0122] Exemplarily, the storage environment parameters can include the pressure value and the temperature. For example, the storage environment parameters can include the recommended storage temperature of minus 0.5 degrees Celsius and the recommended storage vacuum degree of 0.75 standard atmospheric pressure.

[0123] S404. Input the storage environment parameters and the pressure change parameter into the food ingredient freshness preservation environment regulation model to obtain the control parameter.

[0124] S405. Control the operation of the compressor and the vacuum pumping device through the control parameter, so that the environment in the vacuum drawer reaches the storage environment corresponding to the storage environment parameters.

[0125] In this way, by setting the food ingredient freshness preservation environment regulation model in the refrigerator, the refrigerator can be made to adaptively adjust the environment of the vacuum drawer according to the food ingredients stored in the vacuum drawer, and the freshness preservation effect of the vacuum drawer can be improved.

[0126] When the food preservation environment control model is set in the refrigerator, the interaction between the modules of the refrigerator can be seen in Figure 5 as shown in Figure 5 Fig. 4, which is a schematic interaction flow diagram of a control method according to some embodiments.

[0127] As Figure 5 shown, the refrigerator includes a storage module and a pressure change parameter acquisition module.

[0128] The storage module is used to store information of the food in the vacuum drawer, the food importance ranking principle, and the corresponding relationship between multiple foods and storage environment parameters. The pressure change parameter acquisition module is used to acquire pressure change parameters.

[0129] In Figure 5 , the change of the food is caused by the user putting food into or taking food out of the vacuum drawer. Based on this change, the information of the food is updated, and based on the updated food information, the food importance ranking principle, and the corresponding relationship between multiple foods and storage environment parameters, the storage environment parameters corresponding to the target food are determined.

[0130] The storage environment parameters and the pressure change parameters are input into the food preservation environment control model, and the food preservation environment control model outputs the start temperature, shutdown temperature of the compressor, and the target operation duration of the vacuum pumping device. In this way, the operation of the compressor is controlled by the start temperature and shutdown temperature, and the operation of the vacuum pumping device is controlled by the target operation duration, so as to adjust the environment of the vacuum drawer.

[0131] When the food preservation environment control model is set in the cloud device, the control method can be seen in Figure 6 as shown in Figure 6 Fig. 5, which is a schematic flow diagram of a control method of a refrigerator according to some embodiments. Figure 3 .

[0132] As Figure 6 shown, the control method of the refrigerator includes the following steps:

[0133] S601. When it is detected that the door of the vacuum drawer is switched from the open state to the closed state, obtain the food information of multiple foods currently stored in the vacuum drawer.

[0134] When it is detected that the door of the vacuum drawer is switched from the open state to the closed state, obtain the food that the user puts into or takes out of the vacuum drawer; update the information of the food stored in the vacuum drawer according to the food.

[0135] In the present application, a database can be set in the cloud device, and the database is used to store the food information, the food importance ranking principle, and the corresponding relationship between multiple foods and storage environment parameters.

[0136] When the user puts food ingredients into the vacuum drawer, it may include the following two possible implementations:

[0137] In one possible implementation, when the user puts food ingredients into the vacuum drawer, the user can input the information of the food ingredients through the display screen of the refrigerator. After the controller receives the information of the food ingredients input by the user, it sends the food ingredient information to the database in the cloud, updates the information of the food ingredients in the database, and obtains the new food ingredient information.

[0138] In another possible implementation, when the user puts food ingredients into the vacuum drawer, the user can input the information of the food ingredients through the application on the terminal device. The cloud device can update the information of the food ingredients stored in the vacuum drawer in the database with the food ingredient information obtained through the application, and obtain the new food ingredient information.

[0139] When the user takes food ingredients out of the vacuum drawer, it may include the following two possible implementations:

[0140] In one possible implementation, when the user takes food ingredients out of the vacuum drawer, the user can input the information of the taken food ingredients through the display screen of the refrigerator. After the controller receives the information of the food ingredients input by the user, it sends the food ingredient information to the database in the cloud, updates the information of the food ingredients in the database, and obtains the new food ingredient information.

[0141] In another possible implementation, when the user takes food ingredients out of the vacuum drawer, the user can input the information of the taken food ingredients through the application on the terminal device, so that the cloud device can obtain the information of the food ingredients taken by the user through the application, and update the information of the food ingredients stored in the vacuum drawer in the database according to this information, delete the information of the taken food ingredients, and obtain the new food ingredient information.

[0142] S602. According to the preset food ingredient importance sorting principle and food ingredient information in the database, determine the target food ingredients and the corresponding storage environment parameters.

[0143] The food ingredient importance sorting principle can be sorted according to the price of the food ingredients, or according to the freshness preservation duration of the food ingredients, or is user-defined. The embodiments of the present application do not make specific limitations on the food ingredient importance sorting principle.

[0144] For example, the user can customize the food ingredient importance sorting principle through the display screen of the refrigerator or the application on the terminal device.

[0145] Exemplarily, according to the preset sorting principle of ingredient importance and ingredient information, target ingredients can be determined. All the ingredients stored in the vacuum drawer can be sorted according to the sorting principle of ingredient importance based on the ingredient information, and the top N ingredients in terms of importance are determined as the target ingredients. Here, N is an integer greater than or equal to 1.

[0146] Taking the sorting principle of ingredient importance as sorting according to the price of ingredients as an example, according to the preset sorting principle of ingredient importance and ingredient information, the target ingredients can be determined as follows: All the ingredients stored in the vacuum drawer are sorted according to the price based on the ingredient information, and the ingredient ranked first is determined as the target ingredient. For example, the ingredients stored in the vacuum drawer include spinach, Chinese cabbage, and salmon, and since the price of salmon is the highest, salmon can be determined as the target ingredient.

[0147] After the target ingredients are determined, the storage environment parameters corresponding to the target ingredients can be determined from the pre-stored corresponding relationships in the database. For example, when the target ingredient is salmon, the storage environment parameters corresponding to salmon can be determined.

[0148] Exemplarily, the storage environment parameters can include the pressure value and the temperature. For example, the storage environment parameters can include a recommended storage temperature of minus 0.5 degrees Celsius and a recommended storage vacuum of 0.75 standard atmospheric pressure.

[0149] S603. Obtain the pressure change parameter and send the pressure change parameter to the cloud device.

[0150] S604. The cloud device inputs the storage environment parameter and the pressure change parameter into the ingredient freshness preservation environment regulation model to obtain the control parameter, and sends the control parameter to the controller.

[0151] S605. The controller receives the control parameter sent by the cloud device, and controls the operation of the compressor and the vacuum pumping device through the control parameter so that the environment in the vacuum drawer reaches the storage environment corresponding to the storage environment parameter.

[0152] In this way, by setting the ingredient freshness preservation environment regulation model in the cloud device, the resource occupation of the refrigerator controller can be reduced, and to a certain extent, the speed of determining the control parameter can be improved, realizing that the refrigerator adaptively adjusts the environment of the vacuum drawer according to the ingredients stored in the vacuum drawer, and the freshness preservation effect of the vacuum drawer can be improved.

[0153] When the ingredient freshness preservation environment regulation model is set in the cloud device, the interaction between the refrigerator and the cloud device can be seen in the figure shown, Figure 7 which is a schematic diagram of the interaction process of another control method provided according to some embodiments.

[0154] Such as Figure 7As shown, the user can input information about the ingredients put in or taken out through the display screen of the refrigerator. The controller can obtain the information of the ingredients and send the information of the ingredients to the database of the cloud device to update the ingredient information in the database. And the cloud device can determine the target ingredients based on the updated ingredient information and obtain the storage environment parameters corresponding to the target ingredients. The controller in the refrigerator can send the pressure change parameter to the cloud device. The cloud device can input the storage environment parameter and the pressure change parameter into the ingredient freshness preservation environment regulation model, and the ingredient freshness preservation environment regulation model outputs the control parameter. The cloud device sends the control parameter to the controller of the refrigerator. The control parameter includes the start-up temperature and shutdown temperature of the compressor and the target operation duration of the vacuum pumping device.

[0155] The controller controls the operation of the compressor through the start-up temperature and shutdown temperature, and controls the operation of the vacuum pumping device through the target operation duration, so as to adjust the environment of the vacuum drawer.

[0156] In this application, obtaining the pressure change parameter may include, when it is detected that the door of the vacuum drawer is switched from the open state to the closed state, controlling the operation of the vacuum pumping device to reduce the pressure in the vacuum drawer to the target pressure value, and obtaining the time interval for the pressure value to drop to the target pressure value, and determining the time interval as the pressure change parameter.

[0157] The target pressure value can be 0.9 atmospheres, and the embodiments of this application do not make specific limitations on the target pressure value.

[0158] In this way, the time interval for the pressure to drop to the target pressure value can reflect the operation time of the vacuum pumping device and the pressure drop situation in the vacuum drawer from the side, so that the accuracy of the target operation duration of the vacuum pumping device obtained by the ingredient freshness preservation environment regulation model based on the storage environment parameter and the pressure change parameter is higher.

[0159] The refrigerator further includes a pressure switch 24, which is arranged inside the vacuum drawer. For the installation position of the pressure switch 24, reference can be made to Figure 8 shown in Figure 8 which is a schematic diagram of the installation position of a pressure switch according to some embodiments.

[0160] It should be understood that the embodiments of this application only take the installation position of the above pressure switch as an example for illustration and do not constitute any limitation.

[0161] A possible implementation manner of obtaining the pressure change parameter by using the pressure switch can be seen in Figure 9 shown in Figure 9 which is a schematic flowchart of a method for obtaining the pressure change parameter according to some embodiments.

[0162] As Figure 9 shown, the method for obtaining the pressure change parameter may include the following steps:

[0163] S901. Obtain a first signal, which is generated when the pressure in the vacuum drawer is the pressure value of the external environment and the pressure switch in the vacuum drawer switches from the off state to the on state.

[0164] When the pressure in the vacuum drawer is the pressure value of the external environment, the pressure switch switches from the off state to the on state and sends a first signal to the controller, and the controller can receive this first signal.

[0165] Exemplarily, the external pressure value is generally 1 atmospheric pressure. Of course, there may be differences according to different regions.

[0166] S902. Obtain a second signal, which is generated when the pressure in the vacuum drawer is the target pressure value and the pressure switch in the vacuum drawer switches from the on state to the off state.

[0167] When the pressure in the vacuum drawer is the target pressure value, the pressure switch switches from the on state to the off state and sends a second signal to the controller, and the controller can receive this second signal.

[0168] The target pressure value can be 0.9 atmospheric pressure, and the embodiments of the present application do not limit this.

[0169] S903. Determine the time interval between receiving the first signal and receiving the second signal, and determine the time interval as the pressure change parameter.

[0170] Exemplarily, when the controller receives the first signal, it can start timing, and when it receives the second signal, it stops timing, so as to determine the time interval between receiving the first signal and receiving the second signal.

[0171] In this way, by setting a pressure switch in the vacuum drawer, it is possible to obtain the pressure change parameter. Compared with setting a pressure sensor, the cost of the pressure switch is lower, and the cost of the refrigerator can be reduced.

[0172] Combined with the method for obtaining the pressure change parameter, the specific process of the control method of the present application can be seen in Figure 9 as shown, Figure 10 is a schematic flow chart of a control method of a refrigerator according to some embodiments Figure 4 .

[0173] As Figure 10 shown, the control method includes:

[0174] S1001. Enter the information of the type of food ingredients through the refrigerator display screen or the mobile phone APP.

[0175] After the user puts food ingredients into the vacuum drawer or takes food ingredients out of the vacuum drawer, the user can input the information of the type of food ingredients through the refrigerator display screen or the mobile application.

[0176] When inputting the information of the type of food ingredients through the mobile APP, the refrigerator can be configured with a communication module, which can be a WiFi module. The WiFi module can not only receive the information sent by the mobile APP, but also receive the result output by the cloud food ingredient freshness preservation environment regulation model. When the information of the type of food ingredients is input through the refrigerator large screen and the food ingredient freshness preservation environment regulation model is deployed on the refrigerator side, the refrigerator does not need to be configured with a communication module.

[0177] S1002: Input the information of the type of food ingredients into the fresh food preservation database to determine the corresponding recommended storage environment configuration parameters.

[0178] The recommended storage environment configuration parameters are the storage environment parameters described in the above embodiments.

[0179] Input the information of the type of food ingredients into the fresh food preservation database to determine the corresponding recommended storage environment conditions (such as the recommended storage temperature of minus 0.5 degrees Celsius and the recommended storage vacuum degree of 0.75 standard atmospheric pressure). For details, please refer to the content of determining the storage environment parameters described in the above embodiments, which will not be elaborated here.

[0180] S1003: Use the pressure switch set in the vacuum drawer to obtain the pressure change parameters.

[0181] When the pressure in the drawer is lower than 0.9 atmospheres, the pressure switch is disconnected; when the pressure is higher than 0.9 atmospheres, the pressure switch is connected. The pressure switch signal can be fed back to the food ingredient freshness preservation environment regulation model on the side or in the cloud. Combining with the drawer door opening and closing signal, the system can measure the working duration of the vacuum motor to reduce the pressure from 1 atmosphere to 0.9 atmospheres (or other set values such as 0.85). Through these data, the food ingredient freshness preservation environment regulation model can infer the quantity of food ingredients in the vacuum drawer from the side.

[0182] S1004: Input the recommended storage environment configuration parameters and the pressure change parameters into the food ingredient freshness preservation environment regulation model of the refrigerator or cloud device.

[0183] S1005: The food ingredient freshness preservation environment regulation model outputs the start and stop points of the compressor and the working duration of the vacuum motor.

[0184] The start and stop points of the compressor are the start temperature and stop temperature described in the above embodiments. The working duration of the vacuum motor is the target working duration described in the above embodiments.

[0185] For example, the start point is 3 degrees Celsius, the stop point is minus 1 degree Celsius, and the vacuum motor works for 375 seconds.

[0186] The vacuum motor is the vacuum pumping device described in the above embodiments and is used to pump the vacuum of the vacuum drawer.

[0187] S1006. The internal environment of the vacuum drawer reaches the desired conditions.

[0188] In this way, the user can input the types of food ingredients through the large refrigerator screen or the mobile phone APP. Combining the food ingredient fresh-keeping database and the food ingredient environment control model, the vacuum drawer can provide suitable fresh-keeping conditions for different types and quantities of food ingredients, and there is no need to set sensors such as cameras, temperature and humidity, and vacuum degree in the vacuum drawer.
