[0007] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0015] The refrigerator of the embodiment of the present application can control the magnetic field generating device to generate a magnetic field to reach a target magnetic field strength according to the type of goods, so as to carry out targeted preservation of the refrigerated goods according to the type of goods, thereby realizing the function of refined preservation and enhancing the preservation effect of the refrigerated goods; it can also determine the target action time according to the weight of the goods, and control the magnetic field generating device to generate the magnetic field to reach the target action time, and can adjust the action time of the magnetic field generating device according to the weight of the goods to prevent the magnetic field generating device from continuously working within the activation time of the magnetic field preservation function, thereby reducing the energy consumed by the magnetic field generating device, thereby reducing the energy consumption of the refrigerator and improving customer satisfaction.

[0016] In some embodiments of the present application, the controller is further configured to: obtain a third preset correspondence, the third preset correspondence including multiple weight ranges and the action time corresponding to each weight range; and determine the target action time in the third preset correspondence according to the weight of the item.

[0018] In some embodiments of the present application, the controller is also configured to control the magnetic field generating device to generate a magnetic field according to a plurality of preset preservation cycles; wherein the preset preservation cycle includes a start segment and a stop segment, wherein in the start segment, the controller controls the magnetic field generating device to generate a magnetic field, and the duration of the start segment is the target action duration; and in the stop segment, the controller controls the magnetic field generating device to stop generating a magnetic field.

[0019] With such arrangement, the magnetic field generating device can be controlled to perform multiple magnetic field preservation actions on the refrigerated items, so as to further enhance the preservation effect of the refrigerated items and extend the preservation period of the refrigerated items.

[0021] In this way, when the weight of the items to be refrigerated is within the preset weight range, it can be considered that the number of items to be refrigerated in the storage drawer is small or there are no items to be refrigerated. Since the storage drawer is a sealed drawer, the sealed drawer can provide sufficient fresh-keeping conditions, and there is no need to turn on the magnetic field generating device, thereby reducing the energy consumption of the refrigerator and improving the user experience.

[0068] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0069] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0070] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0071] With regard to refrigerators in the related art, there is a technical problem that refrigerators equipped with a magnetic field preservation function have high energy consumption, which reduces customer satisfaction. The inventor has found through research that the reason is that after the magnetic field preservation function is turned on, the magnetic field generating device continues to generate a magnetic field during the duration of the magnetic field preservation function being turned on, and the magnetic field generating device consumes more energy. In particular, when the number of items to be refrigerated in the storage drawer is small or there are no items to be refrigerated, the magnetic field generating device continues to work during the duration of the turn-on, resulting in energy waste, which leads to high energy consumption of the refrigerator and reduces customer satisfaction.

[0072] In view of this, an embodiment of the present application provides a refrigerator and a control method thereof, which obtains the weight of the items to be refrigerated in the storage drawer and adjusts the duration of the magnetic field generated by the magnetic field generating device according to the weight of the items, so as to prevent the magnetic field generating device from continuously working during the activation period of the magnetic field preservation function, thereby reducing the energy consumed by the magnetic field generating device, thereby reducing the energy consumption of the refrigerator and improving customer satisfaction.

[0073] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0074] refer to Figure 1 The refrigerator provided in the embodiment of the present application may include a box body 100, and the box body 100 is configured with a refrigeration compartment 110. Exemplarily, the box body 100 may include an outer shell 120, an inner liner 130 located in the outer shell 120, and a foaming layer filled between the outer shell 120 and the inner liner 130. The inner liner 130 may be configured with a refrigeration compartment 110 for accommodating food and other items. The refrigeration compartment 110 may have a take-in and put-out port, and items may be taken in and put out of the refrigeration compartment 110 through the take-in and put-out port.

[0075] A storage drawer 200 may be provided in the refrigeration compartment 110. Exemplarily, a relative cover plate 140 and a bottom plate 150 may be provided in the refrigeration compartment 110, and the cover plate 140, the bottom plate 150 and the inner tank 130 are arranged to form a drawer compartment, and the storage drawer 200 is arranged in the drawer compartment. The storage drawer 200 is used to accommodate items to be refrigerated, and the items to be refrigerated may include multiple types of items. For example, the multiple types of items may include a first category of items, a second category of items, a third category of items and a fourth category of items. The first category of items may be fruits, the second category of items may be vegetables, the third category of items may be fresh meat, and the fourth category of items may be mushrooms. It can be understood that the items to be refrigerated may also be other types of items, which will not be described in detail in the embodiments of the present application. Exemplarily, the storage drawer 200 may be an open drawer with a top opening. Reference Figure 2 The storage drawer 200 may also be a sealed drawer with a sealing function. The humidity in the sealed drawer may be above 85-90% rh, which may enhance the preservation effect of the refrigerated items. Exemplarily, the sealed drawer may also have a vacuum function to reduce the oxygen concentration, thereby reducing the respiration of the refrigerated items, inhibiting oxidation, inhibiting microbial activity, and further enhancing the preservation effect of the refrigerated items. For example, the oxygen concentration in the sealed drawer with a vacuum function may be below 17%.

[0076] Exemplarily, the sealed drawer may include a drawer body 210 and a cover 220, wherein the drawer body 210 is slidable relative to the inner liner 130 along the extending direction perpendicular to the box body 100, so as to be pulled out of or pushed into the refrigerating compartment 110. The cover 220 is disposed in the refrigerating compartment 110 and connected to the inner liner 130, so as to be separated from the drawer body 210 when the drawer body 210 is pulled out of the refrigerating compartment 110, and to be covered on the drawer body 210 when the drawer body 210 is pushed into the refrigerating compartment 110, and is sealedly connected to the drawer body 210.

[0077] For example, reference Figure 3 , Figure 4 , Figure 5 and Figure 6 , a plurality of storage areas may be formed in the storage drawer 200. The user may classify the items to be refrigerated and place them in different storage areas to perform refined storage of the items to be refrigerated. For example, a partition 270 may be provided in the storage drawer 200, and the partition 270 divides the storage drawer 200 into a plurality of storage areas. The plurality of storage areas may include a first storage area 230, a second storage area 240, a third storage area 250, and a fourth storage area 260. The first storage area 230 may be used to accommodate a first category of items, the second storage area 240 may be used to accommodate a second category of items, the third storage area 250 may be used to accommodate a third category of items, and the fourth storage area 260 may be used to accommodate a fourth category of items.

[0078] The refrigerator may also include a refrigeration system 300 (not shown in the drawings) located in the box 100, and the refrigeration system 300 is configured to provide cold capacity to refrigerate the items to be refrigerated. Exemplarily, the refrigeration system 300 may include a compressor 310, a condenser, a capillary tube, and an evaporator. The compressor 310 is used to compress the refrigerant vapor, generate high-temperature and high-pressure vapor, and transport the refrigerant vapor to the condenser. The condenser is used to liquefy the high-temperature and high-pressure refrigerant vapor, generate high-temperature and low-pressure refrigerant cold liquid, and transport the refrigerant cold liquid to the capillary tube. After the capillary tube depressurizes the refrigerant cold liquid, the high-pressure and low-temperature liquid is converted into a low-pressure and low-temperature refrigerant, and the low-pressure and low-temperature refrigerant is transported to the evaporator. After receiving the low-pressure and low-temperature refrigerant, the evaporator makes it boil under isobaric conditions, absorbs heat and vaporizes to generate cold capacity to reduce the temperature in the refrigeration compartment 110, thereby refrigerating the items to be refrigerated.

[0079] The refrigerator may further include an air guide device 400, which is configured to guide the cold energy generated by the refrigeration system 300 into the refrigeration compartment 110, such as the storage drawer 200 in the refrigeration compartment 110, so as to refrigerate the items to be refrigerated. Figure 2 The air guide device 400 may include a first air duct assembly 410, which is disposed between the storage drawer 200 and the inner liner 130, and the first air duct assembly 410 forms a first air duct. The first air duct assembly 410 is provided with a first air outlet 411 connected to the first air duct, and the first air outlet 411 is opposite to the storage drawer 200. The first air duct assembly 410 may also be provided with a driving fan, which generates cooling air when the driving fan rotates, and the cooling air carries the coldness provided by the refrigeration system 300 and flows out from the first air outlet 411 and blows toward the storage drawer 200, so as to cool the items to be refrigerated in the storage drawer 200.

[0080] In some possible implementations of the present application, the first air outlet 411 may be opposite to the top opening of the storage drawer 200, and the wind flowing out of the first air outlet 411 may be blown directly to the items to be refrigerated. In some other possible implementations of the present application, the air guide device 400 also includes a second air duct assembly 420, which is arranged between the cover 220 and the drawer body 210 and connected to the first air duct assembly 410. A second air duct is formed in the second air duct assembly 420, and the second air duct is connected to the first air duct through the first air outlet 411. A second air outlet connected to the second air duct may also be provided on one side of the second air duct assembly 420 facing the drawer body 210. The cooling wind formed by the driving fan can enter the second air duct from the first air duct, and flow out from the second air outlet to blow to the items to be refrigerated in the storage drawer 200.

[0081] The refrigerator may also include a magnetic field generating device 500, which is configured to generate a magnetic field and cause the magnetic field to act on the items to be refrigerated. The magnetic field acting on the items to be refrigerated can affect gene expression, change the permeability of cell membranes, and reduce the metabolic rate of the items to be refrigerated. The magnetic field can also form more hydrogen bonds, reduce weight loss and juice loss, and delay the softening of tissue structure. The magnetic field can also eliminate hydrogen peroxide and superoxide free radicals in the items to be refrigerated, protect the tissue cells of the items to be refrigerated from oxidative damage, and preserve the items to be refrigerated. In addition, the strong penetration of the magnetic field can effectively penetrate various packaging materials. When the user wraps the items to be refrigerated with packaging materials and then puts them in the refrigerator for storage, the items to be refrigerated still have a good preservation effect.

[0082] Exemplarily, the magnetic field generating device 500 may include at least one magnetic field generating unit 510 capable of generating a magnetic field. For example, the magnetic field generating unit 510 may be an electromagnetic coil or a permanent magnet. Figure 2 , the magnetic field generating unit 510 may include two magnetic components 511, and the two magnetic components 511 may be installed on opposite sides of the storage drawer 200. For example, one of the magnetic components 511 may be disposed between the cover 220 and the first air duct component 410, and the other magnetic component 511 may be disposed between the drawer body 210 and the bottom plate 150. The magnetic component 511 may be connected to the storage drawer 200 by bolts.

[0083] For example, reference Figure 6 When the storage drawer 200 has multiple storage areas, there may also be multiple magnetic field generating units 510. Each storage area is correspondingly provided with a magnetic field generating unit 510, and the magnetic field generated by the magnetic field generating unit 510 acts on the objects to be refrigerated in the corresponding storage area.

[0084] The refrigerator of the embodiment of the present application may also include an information acquisition device 700, which is configured to obtain type determination information of the items to be refrigerated, and the type determination information is used to determine the type of the items to be refrigerated. Exemplarily, the information acquisition device 700 may be a camera 710, and the camera 710 is used to obtain an image of the items to be refrigerated, and the image of the item is the type determination information. The type of the items to be refrigerated can be determined based on the image of the item. The camera 710 can be installed on the top surface inside the storage drawer 200. Exemplarily, the top surface inside the storage drawer 200 may also be provided with a rotating device, which is connected to the camera 710 and can drive the camera 710 to rotate. For example, the rotating device can cause the camera 710 to rotate in the horizontal direction within an angle range of 0 to 360 degrees, and in the vertical direction within an angle range of 0 to 90 degrees.

[0085] Exemplarily, the information acquisition device 700 may also be an item category button. When the item category button is pressed, a pressing signal is generated, and the pressing signal is the category determination information. The item category of the item to be refrigerated may be determined according to the pressing signal. Exemplarily, the item category button may be a physical button. The item category button may also be a touch button provided on the touch screen 720. The touch screen 720 may be provided on the cover plate 140 in the refrigeration chamber 110.

[0086] The refrigerator of the embodiment of the present application also includes a weight measuring device 800, which is configured to measure the weight of the items to be refrigerated. Exemplarily, the weight measuring device 800 may include at least one weight measuring unit for measuring weight, and the weight measuring unit may be a weight sensor, which may be installed on the bottom surface of the storage drawer 200. Exemplarily, when the storage drawer 200 has multiple storage areas, there may also be multiple weight measuring units. Each storage area is correspondingly provided with a weight measuring unit, which is used to measure the weight of the items to be refrigerated in the corresponding storage area.

[0087] refer to Figure 7The refrigerator of the embodiment of the present application further includes a controller 600, which can be electrically connected to the magnetic field generating device 500, the information acquisition device 700 and the weight measuring device 800. The controller 600 is configured to determine the type of the item to be refrigerated according to the type determination information, and control the magnetic field generating device 500 to generate a magnetic field to reach the target magnetic field strength according to the type of the item, so as to carry out targeted preservation of the refrigerated items according to the type of the item, thereby realizing the function of refined preservation and enhancing the preservation effect of the refrigerated items. The controller 600 is also configured to obtain the weight of the item, determine the target action time according to the weight of the item, and control the magnetic field generating device 500 to generate a magnetic field to reach the target action time, and can adjust the action time of the magnetic field generated by the magnetic field generating device 500 according to the weight of the item to prevent the magnetic field generating device 500 from continuously working during the activation time of the magnetic field preservation function, thereby reducing the energy consumed by the magnetic field generating device 500, thereby reducing the energy consumption of the refrigerator and improving customer satisfaction.

[0088] The controller 600 may also be electrically connected to the refrigeration system 300 to control the refrigeration system 300 .

[0089] The embodiment of the present application also provides a refrigerator control method, which is used to control the above refrigerator. Figure 8 , the control method may include the following steps:

[0090] S100: Acquire type determination information of the articles to be refrigerated generated by an information acquisition device, and determine the types of the articles to be refrigerated according to the type determination information.

[0091] The controller 600 may automatically obtain the type determination information of the article to be refrigerated generated by the information acquisition device 700 .

[0092] Exemplarily, the information acquisition device 700 may be a camera 710 electrically connected to the controller 600. The controller 600 may generate a first control signal according to a preset fresh-keeping start cycle, and send the first control signal to the camera 710. For example, the preset fresh-keeping start cycle may be 24 hours. The camera 710 photographs the refrigerated item in response to the first control signal to obtain an item image of the refrigerated item, and the item image is the type determination information. The controller 600 may determine the item type according to the item image. For example, the controller 600 may analyze the item image to obtain an item type feature value, and input the item type feature value into a pre-trained item type recognition model to obtain the item type of the refrigerated item. The camera 710 may automatically obtain the item image of the refrigerated item, and the controller 600 may automatically determine the item type according to the item image, thereby realizing automatic identification of the item type without the user having to perform additional operations, thereby improving the intelligence of the refrigerator, and improving the convenience of user operation and the user experience effect.

[0093] When the storage drawer 200 has multiple storage areas, the camera 710 can take pictures of the items to be refrigerated in the multiple storage areas in the storage drawer 200 to obtain the item images of the items to be refrigerated in the multiple storage areas. For example, the camera 710 can have a sufficiently large field of view so that the items to be refrigerated in the multiple storage areas can be clearly imaged in the same item image. When the controller 600 analyzes the item images, the item types of the items to be refrigerated in the multiple storage areas can be obtained at the same time.

[0094] Alternatively, the controller 600 may also generate a rotation drive signal and send the rotation drive signal to the rotation device. The rotation device drives the camera 710 to rotate in response to the rotation drive signal to respectively photograph the items to be refrigerated in each storage area, thereby obtaining an item image of the items to be refrigerated in each storage area. The controller 600 may respectively analyze the item images of the items to be refrigerated in each storage area to obtain the item types of the items to be refrigerated in multiple storage areas.

[0095] The controller 600 may also acquire category determination information in response to a user's operation.

[0096] Exemplarily, the information acquisition device 700 may also be a plurality of item type buttons electrically connected to the controller 600, and a press signal is generated when the item type button is pressed. The controller 600 may determine the item type based on the press signal. After the user places the item to be refrigerated in the storage drawer 200, the user may press the item type button corresponding to the item to be refrigerated to generate a press signal, and send the press signal to the controller 600. The controller 600 receives the press signal, analyzes the press signal, and determines the item type of the item to be refrigerated. By setting a plurality of item type buttons, the magnetic field preservation function may be activated based on the user's operation, thereby enriching the activation method of the magnetic field preservation function and improving the user experience.

[0097] Exemplarily, the plurality of item category buttons may include a first item category button, a second item category button, a third item category button, and a fourth item category button. The first item category button corresponds to the first category of items, and a first press signal is generated when the first item category button is pressed. The second item category button corresponds to the second category of items, and a second press signal is generated when the second item category button is pressed. The third item category button corresponds to the third category of items, and a third press signal is generated when the third item category button is pressed. The fourth item category button corresponds to the fourth category of items, and a fourth press signal is generated when the fourth item category button is pressed. For example, when the user needs to refrigerate the first category of items, the first category of items may be placed in the storage drawer 200. Then, the user may press the first item category button to generate a first press signal, and send the first press signal to the controller 600. After receiving the first press signal, the controller 600 may analyze the first press signal and determine that the items to be refrigerated in the storage drawer 200 are the first category of items.

[0098] Exemplarily, when the storage drawer 200 has multiple storage areas, the user can perform fine storage of multiple types of items to be refrigerated in the storage drawer 200 at the same time. For example, the multiple storage areas may include a first storage area 230, a second storage area 240, a third storage area 250, and a fourth storage area 260. If the user needs to refrigerate the first category of items and the second category of items, the first category of items can be placed in the first storage area 230, and the second category of items can be placed in the second storage area 240. Then, the user presses the first category of items button and the second category of items button respectively to generate a first press signal and a second press signal, and sends the first press signal and the second press signal to the controller 600. After receiving the first press signal and the second press signal, the controller 600 can analyze the first press signal and the second press signal to determine that the items to be refrigerated in the first storage area 230 are the first category of items, and the items to be refrigerated in the second storage area 240 are the second category of items.

[0099] Exemplarily, the refrigerator may also be provided with a smart button electrically connected to the controller 600, and a signal is automatically activated when the smart button is pressed. The controller 600 may automatically obtain the type determination information in response to the automatic activation signal to automatically identify the type of the item to be refrigerated. Fig. 9 The control method of the refrigerator in the embodiment of the present application may further include the following steps:

[0100] S110, obtaining an automatic start signal generated by a smart button;

[0101] For example, after placing the items to be refrigerated in the storage drawer 200, the user may press the smart button. The pressed smart button generates an automatic identification signal and sends the automatic identification signal to the controller 600, and the controller 600 obtains the automatic start signal.

[0102] S120: Generate a first control signal according to the automatic start signal, and send the first control signal to the camera, where the first control signal is used to control the camera to obtain an image of the object to be refrigerated.

[0103] After receiving the automatic identification signal, the controller 600 generates a first control signal and sends the first control signal to the camera 710 to control the camera 710 to obtain an image of the object, thereby determining the type of the object to be refrigerated according to the image of the object, thereby realizing automatic identification of the type of the object.

[0104] For example, after placing the items to be refrigerated in the storage drawer 200, if the user does not press the corresponding item type button or the smart button, the controller 600 can generate a first control signal after a preset waiting time to control the camera 710 to obtain an item image, thereby determining the item type of the items to be refrigerated. This arrangement can prevent the user from automatically obtaining the item type of the items to be refrigerated when there is no operation or misoperation by the user, so as to facilitate the subsequent targeted preservation of the items to be refrigerated and enhance the preservation effect of the items to be refrigerated.

[0105] S200, controlling the magnetic field generating device to generate a magnetic field to reach a target magnetic field strength according to the type of the object.

[0106] After determining the type of item, the controller 600 can control the magnetic field generating device 500 to generate a magnetic field to achieve a target magnetic field strength according to the type of item, so as to carry out targeted preservation of the refrigerated items, prevent the refrigerated items from spoiling or insufficient preservation due to excessively high or low magnetic field strength, and improve the preservation effect of the refrigerated items.

[0107] Exemplarily, the controller 600 can obtain a first preset correspondence, which includes multiple types of items and the magnetic field strength corresponding to each type of item. The controller 600 can determine the target magnetic field strength in the first preset correspondence according to the type of item. Exemplarily, the refrigerator may also include a memory electrically connected to the controller 600, and the memory is used to store data. The first preset correspondence can be stored in the memory in the form of a database. Through the first preset correspondence, the target magnetic field strength of the magnetic field generating device 500 can be conveniently determined according to the type of item, so as to carry out targeted preservation of the refrigerated items, prevent the problem of spoilage or insufficient preservation of the refrigerated items due to excessively high or low magnetic field strength, and improve the preservation effect of the refrigerated items. The first preset correspondence can be shown in Table 1.

[0108] For example, when the controller 600 determines that the type of items to be refrigerated is the first category of items such as fruits, the target magnetic field strength is determined to be 6mT~10mT in the second preset relationship shown in Table 1, and the magnetic field generating device 500 is controlled to generate a magnetic field with a magnetic field strength of 6mT~10mT.

[0109] Table 1

[0110] Item Type Magnetic field strength (mT) Fruits and other first-class items 6～10 Second category items such as vegetables 3～6 Fresh meat and other third-category items 1～3 Fungi and other fourth category items 3～6

[0111] In some possible embodiments of the present application, the controller 600 can also control the refrigeration system 300 to provide cooling capacity according to the type of items, so that the storage drawer 200 reaches the target refrigeration temperature. In this way, the refrigeration temperature of the refrigerated items can be adjusted according to the type of items, so that the refrigerated items are at a refrigeration temperature suitable for storage, thereby extending the shelf life of the refrigerated items.

[0112] refer to Fig.10 The control method of the embodiment of the present application may also include the following steps:

[0113] S210, determining a target refrigeration temperature according to the type of item;

[0114] Exemplarily, the controller 600 may obtain a second preset correspondence, which includes multiple types of items and a refrigeration temperature corresponding to each type of item. The controller 600 may determine the target refrigeration temperature in the second preset correspondence according to the type of item. The second preset correspondence may be stored in the memory in a database manner. The second preset correspondence may be as shown in Table 2.

[0115] Table 2

[0116]

[0117]

[0118] For example, when the items to be refrigerated are first-category items such as fruits and second-category items such as vegetables, the target refrigeration temperature may be 2° C. to 6° C. When the items to be refrigerated are third-category items such as fresh meat, the target refrigeration temperature may be -5° C. to 0° C.

[0119] S220: Control the refrigeration system so that the refrigeration temperature in the storage drawer reaches the target refrigeration temperature.

[0120] For example, the controller 600 may control the start and stop time of the compressor 310 in the refrigeration system 300 so that the refrigeration temperature in the storage drawer 200 reaches the target refrigeration temperature.

[0121] Exemplarily, when the storage drawer 200 has multiple storage areas, the magnetic field generating device 500 includes multiple magnetic field generating units 510. A magnetic field generating unit 510 may be correspondingly arranged in each storage area, and the magnetic field generated by the magnetic field generating unit 510 acts on the items to be refrigerated in the corresponding storage area. The controller 600 may determine the type of items to be refrigerated in each storage area according to the type determination information, and control the corresponding magnetic field generating unit 510 to reach the target magnetic field strength according to the type of items to be refrigerated in each storage area. In this way, different types of items to be refrigerated can be placed in the same storage drawer 200, which improves the flexibility of storing items to be refrigerated; and different types of items to be refrigerated in different storage areas can be kept fresh under the action of magnetic fields of different magnetic field strengths, which improves the difference in fresh-keeping conditions of different types of items to be refrigerated, prevents different types of items to be refrigerated in the same storage drawer 200 from being stored under the same conditions, and has a strong fresh-keeping effect on each type of items to be refrigerated, thereby improving the user experience.

[0122] S300, controlling the weight measuring device to obtain the weight of the article to be refrigerated, determining the target action time according to the weight of the article, and controlling the magnetic field generating device to generate the magnetic field to achieve the target action time.

[0123] The controller 600 can control the weight sensor to obtain the weight of the items to be refrigerated placed in the storage drawer 200, then determine the target action time according to the weight of the items, and control the magnetic field generating device 500 to generate a magnetic field to achieve the target action time, thereby adjusting the action time of the magnetic field generated by the magnetic field generating device 500 according to the weight of the items to be refrigerated, which can prevent the magnetic field generating device 500 from continuously working within the activation time of the magnetic field preservation function, thereby reducing the energy consumed by the magnetic field generating device 500, thereby reducing the energy consumption of the refrigerator and improving customer satisfaction.

[0124] Exemplarily, the controller 600 can obtain a third preset correspondence, which includes multiple weight ranges and the action time corresponding to each weight range. The controller 600 can determine the target action time in the third preset correspondence according to the weight of the item. Exemplarily, the third preset correspondence can be stored in the memory in the form of a database. Through the third preset correspondence, the target action time of the magnetic field generating device 500 can be conveniently determined according to the type of item, so as to carry out targeted preservation of the refrigerated items, prevent the problem of spoilage or insufficient preservation of the refrigerated items due to excessively high or low magnetic field intensity, and improve the preservation effect of the refrigerated items. The third preset correspondence can be shown in Table 3.

[0125] Table 3

[0126] Item weight W(g) Duration of action (h) 0g≤W≤200g 0 200g<W≤1000g 1 1000g<W≤2000g 2 2000g<W≤5000g 3 W>5000g 4

[0127] For example, when the weight of the article to be refrigerated is 1500 g, which is within the weight range of 1000 g<W≤2000 g, the target action time is determined to be 2 hours.

[0128] Exemplarily, when the storage drawer 200 is a sealed drawer, the controller 600 can also determine whether the weight of the item is within a preset weight range. If the weight of the item is within the preset weight range, the controller 600 determines that the target action time is 0. If the weight of the item exceeds the upper limit of the preset weight range, the controller 600 determines that the target action time is greater than 0. For example, the preset weight range may be 0g≤W≤200g. When the weight of the items to be refrigerated is within the preset weight range, it can be considered that the number of items to be refrigerated in the storage drawer 200 is small or there are no items to be refrigerated. Since the storage drawer 200 is a sealed drawer, the sealed drawer can provide sufficient fresh-keeping conditions, and there is no need to turn on the magnetic field generating device 500, thereby reducing the energy consumption of the refrigerator and improving the user experience.

[0129] Exemplarily, the controller 600 can also control the magnetic field generating device 500 to generate a magnetic field according to a plurality of preset fresh-keeping cycles. The preset fresh-keeping cycle includes an on segment and a stop segment. In the on segment, the controller 600 controls the magnetic field generating device 500 to generate a magnetic field, and the duration of the on segment is the target action duration. In the stop segment, the controller 600 controls the magnetic field generating device 500 to stop generating a magnetic field. With such a configuration, the magnetic field generating device 500 can be controlled to perform multiple magnetic field fresh-keeping effects on the refrigerated items, so as to further enhance the fresh-keeping effect of the refrigerated items and extend the fresh-keeping period of the refrigerated items.

[0130] Exemplarily, the preset fresh-keeping start cycle may be an integer multiple of the preset fresh-keeping cycle. For example, the preset fresh-keeping start cycle may be 24 hours, and the preset fresh-keeping cycle may be 8 hours. In this way, multiple complete preset fresh-keeping cycles may be implemented within the preset fresh-keeping start cycle to ensure the fresh-keeping effect of the items to be refrigerated. The duration of the start segment and the stop segment of the preset fresh-keeping cycle may be as shown in Table 4.

[0131] Table 4

[0132]

[0133]

[0134] For example, when the weight of the item to be refrigerated is 1500g, which is within the weight range of 1000g<W≤2000g, the start section of the preset fresh-keeping cycle is determined to be 2h and the stop section is 4h. The controller 600 controls the magnetic field generating device 500 to generate a magnetic field for 2h and stops generating a magnetic field for 6h. The controller 600 controls the magnetic field generating device 500 to generate a magnetic field for 2h and stops generating a magnetic field for 6h again, until the magnetic field generating device 500 is controlled to complete three preset fresh-keeping cycles.

[0135] Exemplarily, the weight measuring device 800 may include a plurality of weight measuring units. A weight measuring unit is correspondingly arranged in each storage area, and the weight measuring unit is used to measure the weight of the items to be refrigerated in the corresponding storage area. The controller 600 may also determine the corresponding target action time according to the weight of the items to be refrigerated in each storage area, and control the magnetic field generating unit 510 corresponding to the storage area to generate a magnetic field to reach the corresponding target action time. With such a configuration, the items to be refrigerated of different types in different storage areas can be preserved under the action of magnetic fields of different target action times, thereby improving the difference in preservation conditions of the items to be refrigerated of different types, preventing the items to be refrigerated of different types in the same storage drawer 200 from being stored under the same conditions, and having a strong preservation effect on the items to be refrigerated of each type, thereby improving the user experience.

[0136] The control method of the embodiment of the present application can also realize the food management function. For example, when the user places the items to be refrigerated in the storage drawer 200, the camera 710 can obtain the item images of the items to be refrigerated in multiple different storage areas in the storage drawer 200. The controller 600 can determine the storage days of the items to be refrigerated based on the item images of the items to be refrigerated, and obtain the shelf life data of the items to be refrigerated in the memory, and issue a shelf life reminder to the user. For example, the controller 600 can display a shelf life reminder to the user on the display screen on the refrigerator to prevent the items to be refrigerated in the storage drawer 200 from overdue deterioration and improve the user experience.

[0137] The embodiments of the present application also provide a computer-readable storage medium, which may include: a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a disk or an optical disk, and other media that can store program codes. Specifically, the computer-readable storage medium stores program instructions, and the program instructions are used for the methods in the above embodiments.

[0138] The embodiment of the present application also provides a program product, which includes an execution instruction, which is stored in a readable storage medium. At least one control module of the display device can read the execution instruction from the readable storage medium, and at least one control module executes the execution instruction so that the display device implements the handwriting erasing method provided by the various embodiments described above.
