[0012] A weight measuring device configured to measure the weight of the items to be refrigerated;

[0013] A controller, electrically connected to the magnetic field generating device, the information acquisition device, and the weight measuring device, is configured to determine the type of the item to be refrigerated according to the determined information of the type, and control the magnetic field generating device to generate a magnetic field to reach a target magnetic field intensity according to the type of the item; the controller is further configured to acquire the weight of the item, determine a target action duration according to the weight of the item, and control the magnetic field generating device to generate a magnetic field for the target action duration.

[0014] The refrigerator according to the embodiment of the present application can control the magnetic field generating device to generate a magnetic field to reach a target magnetic field intensity according to the type of the item, so as to perform targeted freshness preservation on the item to be refrigerated according to the type of the item, thereby realizing the function of refined freshness preservation and enhancing the freshness preservation effect on the item to be refrigerated; it can also determine the target action duration according to the weight of the item, and control the magnetic field generating device to generate a magnetic field for the target action duration, and can adjust the action duration of the magnetic field generated by the magnetic field generating device according to the weight of the item, so as to prevent the magnetic field generating device from continuously working during the opening duration of the magnetic field freshness preservation function, reduce the energy consumed by the magnetic field generating device, thereby reducing the energy consumption of the refrigerator and improving customer satisfaction.

[0015] In some embodiments of the present application, the controller is further configured to: acquire a third preset correspondence, the third preset correspondence includes a plurality of weight ranges, and the action duration corresponding to each weight range; determine the target action duration in the third preset correspondence according to the weight of the item.

[0016] With such a setting, through the third preset correspondence, the target action duration of the magnetic field generating device can be conveniently determined according to the type of the item, so as to perform targeted freshness preservation on the item to be refrigerated, and prevent the problem of spoilage or insufficient freshness preservation of the item to be refrigerated caused by too high or too low magnetic field intensity, and improve the freshness preservation effect on the item to be refrigerated.

[0017] In some embodiments of the present application, the controller is further configured to control the magnetic field generating device to generate a magnetic field according to a plurality of preset freshness preservation cycles; wherein, the preset freshness preservation cycle includes an opening section and a stopping section, in the opening section, the controller controls the magnetic field generating device to generate a magnetic field, and the duration of the opening section is the target action duration; in the stopping section, the controller controls the magnetic field generating device to stop generating a magnetic field.

[0018] With such a setting, the magnetic field generating device can be controlled to perform multiple magnetic field freshness preservation actions on the item to be refrigerated, so as to further enhance the freshness preservation effect on the item to be refrigerated and extend the freshness preservation period of the item to be refrigerated.

[0019] In some embodiments of the present application, the storage drawer is a sealed drawer; the controller is further configured to: determine whether the weight of the item is within a preset weight range.

[0067] To make the purpose, 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 of the embodiments of this application, rather than all the embodiments.

[0068] It should be noted that the brief description of the terms in this application is only for the convenience of understanding the subsequent described implementation manners, rather than intending to limit the implementation manners of this application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0069] In addition, the terms "include" and "have" and any of their variations 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.

[0070] Regarding the refrigerators in the related art, there is a technical problem that the energy consumption of refrigerators configured with a magnetic field freshness preservation function is relatively high, reducing customer satisfaction. After research by the inventor, it is found that the reason is as follows: After the magnetic field freshness preservation function is turned on, the magnetic field generating device continuously generates a magnetic field during the activation duration of the magnetic field freshness preservation function, and the magnetic field generating device consumes a relatively large amount of energy. Especially 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 still continuously operates during the activation duration, resulting in energy waste, thus leading to relatively high energy consumption of the refrigerator and reducing customer satisfaction.

[0071] In view of this, the embodiments of this application provide a refrigerator and its control method, which obtain the weight of the items to be refrigerated in the storage drawer and adjust the action duration of the magnetic field generated by the magnetic field generating device according to the item weight, so as to prevent the magnetic field generating device from continuously operating during the activation duration of the magnetic field freshness preservation function, reduce the energy consumed by the magnetic field generating device, thereby reducing the energy consumption of the refrigerator and improving customer satisfaction.

[0072] The technical solution of the present application will be described in detail below in conjunction with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0073] Referring to Figure 1 , the refrigerator provided by the embodiment of the present application may include a box body 100, and the box body 100 is configured with a refrigerating compartment 110. Exemplarily, the box body 100 may include an outer shell 120, an inner liner 130 located inside 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 refrigerating compartment 110 for accommodating items such as food ingredients. The refrigerating compartment 110 may have an access opening, and items can be taken in and out of the refrigerating compartment 110 through the access opening.

[0074] A storage drawer 200 may be provided in the refrigerating compartment 110. Exemplarily, opposite cover plates 140 and bottom plates 150 may be provided in the refrigerating compartment 110. The cover plates 140, the bottom plates 150 and the inner liner 130 enclose a drawer compartment, and the storage drawer 200 is arranged in the drawer compartment. The storage drawer 200 is used for accommodating 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 type of item, a second type of item, a third type of item, and a fourth type of item. The first type of item may be fruits, the second type of item may be vegetables, the third type of item may be fresh meat, and the fourth type of item may be fungi. It can be understood that the items to be refrigerated may also be other types of items, which will not be described again in the embodiments of the present application. Exemplarily, the storage drawer 200 may be an open drawer with an open top. Referring to Figure 2 , the storage drawer 200 may also be a sealed drawer with a sealing function. The humidity inside the sealed drawer may be above 85-90% rh, which can enhance the freshness preservation effect of the items to be refrigerated. Exemplarily, the sealed drawer may also have a vacuum function to reduce the oxygen concentration, thereby reducing the respiration of the items to be refrigerated, inhibiting the oxidation effect, and inhibiting the activity of microorganisms, further enhancing the freshness preservation effect of the items to be refrigerated. For example, the oxygen concentration inside the sealed drawer with a vacuum function can reach below 17%.

[0075] Exemplarily, the sealed drawer may include a drawer body 210 and a cover body 220. The drawer body 210 is slidable relative to the inner liner 130 along the extending direction perpendicular to the box body 100 to be pulled out or pushed into the refrigerating compartment 110 from the refrigerating compartment 110. The cover body 220 is arranged in the refrigerating compartment 110 and is connected to the inner liner 130 to be separated from the drawer body 210 when the drawer body 210 is pulled out from the refrigerating compartment 110, and to cover the drawer body 210 and be hermetically connected to the drawer body 210 when the drawer body 210 is pushed into the refrigerating compartment 110.

[0076] Exemplarily, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 , multiple storage areas can be formed within the storage drawer 200. The user can classify the items to be refrigerated and place them in different storage areas for refined storage of the items to be refrigerated. For example, a partition 270 can be provided within the storage drawer 200, and the partition 270 divides the storage drawer 200 into multiple storage areas. The multiple storage areas can 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 can be used to accommodate the first type of items, the second storage area 240 can be used to accommodate the second type of items, the third storage area 250 can be used to accommodate the third type of items, and the fourth storage area 260 can be used to accommodate the fourth type of items.

[0077] The refrigerator may further include a refrigeration system 300 (not shown in the drawings) located within the cabinet 100. The refrigeration system 300 is configured to provide cooling 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 into the condenser. The condenser is used to liquefy the high-temperature and high-pressure refrigerant vapor, generate high-temperature and low-pressure refrigerant liquid, and transport the refrigerant liquid to the capillary tube. After the capillary tube reduces the pressure of the refrigerant liquid, the high-pressure and low-temperature liquid is transformed into 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 causes it to boil under isobaric conditions, absorb heat and vaporize to generate cooling capacity, so as to reduce the temperature within the refrigerating compartment 110, thereby refrigerating the items to be refrigerated.

[0078] The refrigerator may further include an air guiding device 400. The air guiding device 400 is configured to direct the cooling capacity generated by the refrigeration system 300 into the refrigerating compartment 110, such as into the storage drawer 200 within the refrigerating compartment 110, to refrigerate the items to be refrigerated. Exemplarily, referring to Figure 2 , the air guiding device 400 may include a first air duct assembly 410. The first air duct assembly 410 is disposed between the storage drawer 200 and the inner liner 130. 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 communicating with the first air duct. The first air outlet 411 faces the storage drawer 200. The first air duct assembly 410 may further be provided with a driving fan. When the driving fan rotates, it forms a refrigerating air flow. The refrigerating air flow carries the cooling capacity provided by the refrigeration system 300 and flows out from the first air outlet 411 and blows towards the storage drawer 200 to refrigerate the items to be refrigerated located within the storage drawer 200.

[0079] In some possible implementation manners of the embodiments of the present application, the first air outlet 411 may be opposite to the top opening of the storage drawer 200, and the air flowing out from the first air outlet 411 can directly blow onto the item to be refrigerated. In some other possible implementation manners of the embodiments of the present application, the air guiding device 400 further includes a second air duct assembly 420. The second air duct assembly 420 is disposed between the cover body 220 and the drawer body 210 and is 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 communicated with the first air duct through the first air outlet 411. A second air outlet communicating with the second air duct may further be disposed on the side of the second air duct assembly 420 facing the drawer body 210. The refrigerating air formed by driving the fan can enter the second air duct from the first air duct and flow out from the second air outlet to blow onto the item to be refrigerated in the storage drawer 200.

[0080] The refrigerator may further include a magnetic field generating device 500. The magnetic field generating device 500 is configured to generate a magnetic field and make the magnetic field act on the item to be refrigerated. The magnetic field acting on the item to be refrigerated can affect the gene expression, change the cell membrane permeability, and reduce the metabolic rate of the item to be refrigerated. The magnetic field can also form more hydrogen bonds, reduce weight loss and juice loss, and delay the softening of the tissue structure. The magnetic field can also eliminate hydrogen peroxide and superoxide radicals in the item to be refrigerated, protect the tissue cells of the item to be refrigerated from oxidative damage, so as to preserve the item to be refrigerated. In addition, the strong penetrability of the magnetic field can effectively penetrate various packaging materials. When the user wraps the item to be refrigerated with packaging materials and then puts it into the refrigerator for storage, the magnetic field still has a good preservation effect on the item to be refrigerated.

[0081] 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, etc. Refer to Figure 2 , the magnetic field generating unit 510 may include two magnetic components 511. 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 body 220 and the first air duct assembly 410, and the other magnetic component 511 may be disposed between the drawer body 210 and the bottom plate 150. The magnetic component 511 can be connected to the storage drawer 200 by bolts.

[0082] Exemplarily, refer to 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 item to be refrigerated in the corresponding storage area.

[0083] The refrigerator according to the embodiment of the present application may further include an information acquisition device 700, which is configured to acquire the type determination information of the item to be refrigerated, and the type determination information is used to determine the type of the item to be refrigerated. Exemplarily, the information acquisition device 700 may be a camera 710, and the camera 710 is used to acquire the item image of the item to be refrigerated, and the item image is the type determination information. The type of the item to be refrigerated can be determined according to the item image. The camera 710 may be installed on the top surface inside the storage drawer 200. Exemplarily, a rotating device may further be provided on the top surface inside the storage drawer 200, and the rotating device is connected to the camera 710 and can drive the camera 710 to rotate. For example, the rotating device can make the camera 710 rotate within an angle range of 0 to 360° in the horizontal direction and within an angle range of 0 to 90° in the vertical direction.

[0084] Exemplarily, the information acquisition device 700 may also be an item type button. When the item type button is pressed, a pressing signal is generated, and the pressing signal is the type determination information. The type of the item to be refrigerated can be determined according to the pressing signal. Exemplarily, the item type button may be a physical button. The item type 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 refrigerating compartment 110.

[0085] The refrigerator according to the embodiment of the present application further includes a weight measurement device 800, which is configured to measure the item weight of the item to be refrigerated. Exemplarily, the weight measurement device 800 may include at least one weight measurement unit for weighing, and the weight measurement unit may be a weight sensor, and the weight sensor may be installed on the bottom surface inside the storage drawer 200. Exemplarily, when the storage drawer 200 has multiple storage areas, there may also be multiple weight measurement units. Each storage area is correspondingly provided with a weight measurement unit, and this weight measurement unit is used to measure the item weight of the item to be refrigerated in the corresponding storage area.

[0086] Reference Figure 7, the refrigerator according to the embodiment of the present application further includes a controller 600, and the controller 600 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 intensity according to the item type, so as to perform targeted preservation on the item to be refrigerated according to the item type, thereby realizing the function of refined preservation and enhancing the preservation effect of the item to be refrigerated. The controller 600 is further configured to obtain the item weight, determine the target action duration according to the item weight, and control the magnetic field generating device 500 to generate a magnetic field to reach the target action duration, and can adjust the action duration of the magnetic field generated by the magnetic field generating device 500 according to the item weight, so as to prevent the magnetic field generating device 500 from continuously working during the opening duration of the magnetic field preservation function, reduce the energy consumed by the magnetic field generating device 500, thereby reducing the energy consumption of the refrigerator and improving customer satisfaction.

[0087] The controller 600 can also be electrically connected to the refrigeration system 300 to control the refrigeration system 300.

[0088] The embodiment of the present application further provides a control method for a refrigerator, which is used to control the above-mentioned refrigerator. Refer to Figure 8 , the control method may include the following steps:

[0089] S100. Obtain the type determination information of the item to be refrigerated generated by the information acquisition device, and determine the type of the item to be refrigerated according to the type determination information.

[0090] The controller 600 can automatically obtain the type determination information of the item to be refrigerated generated by the information acquisition device 700.

[0091] Exemplarily, the information acquisition device 700 can be a camera 710 electrically connected to the controller 600. The controller 600 can generate a first control signal according to a preset preservation start period and send the first control signal to the camera 710. For example, the preset preservation start period can be 24h. The camera 710 takes a picture of the item to be refrigerated in response to the first control signal to obtain an item image of the item to be refrigerated, and the item image is the type determination information. The controller 600 can determine the item type according to the item image. For example, the controller 600 can 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 type of the item to be refrigerated. Through the camera 710, the item image of the item to be refrigerated can be automatically obtained, and the controller 600 can automatically determine the item type according to the item image, realizing the automatic recognition of the item type, without the need for additional operations by the user, improving the intelligence level of the refrigerator, and enhancing the convenience of user operation and the user experience effect.

[0092] 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 within the storage drawer 200 to obtain 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 angle to clearly image the items to be refrigerated in the multiple storage areas in the same item image. When the controller 600 analyzes the item image, the types of the items to be refrigerated in the multiple storage areas can be obtained simultaneously.

[0093] Alternatively, the controller 600 can 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 take pictures of the items to be refrigerated in each storage area respectively, so as to obtain item images of the items to be refrigerated in each storage area. The controller 600 can analyze the item images of the items to be refrigerated in each storage area respectively to obtain the types of the items to be refrigerated in the multiple storage areas.

[0094] The controller 600 can also obtain the type determination information in response to the user's operation.

[0095] Exemplarily, the information acquisition device 700 can also be a plurality of item type buttons electrically connected to the controller 600. When the item type buttons are pressed, a pressing signal is generated. The controller 600 can determine the item type according to the pressing signal. After the user places the item to be refrigerated in the storage drawer 200, the user can press the item type button corresponding to the item to be refrigerated to generate a pressing signal and send the pressing signal to the controller 600. The controller 600 receives the pressing signal, analyzes the pressing signal, and determines the type of the item to be refrigerated. By setting a plurality of item type buttons, the magnetic field freshness preservation function can be started based on the user's operation, enriching the starting methods of the magnetic field freshness preservation function and improving the user experience.

[0096] Exemplarily, the multiple item type buttons may include a first item type button, a second item type button, a third item type button, and a fourth item type button. The first item type button corresponds to the first type of item, and when the first item type button is pressed, a first pressing signal is generated. The second item type button corresponds to the second type of item, and when the second item type button is pressed, a second pressing signal is generated. The third item type button corresponds to the third type of item, and when the third item type button is pressed, a third pressing signal is generated. The fourth item type button corresponds to the fourth type of item, and when the fourth item type button is pressed, a fourth pressing signal is generated. For example, when the user needs to refrigerate the first type of item, the first type of item can be placed in the storage drawer 200. Then, the user can press the first item type button to generate a first pressing signal and send the first pressing signal to the controller 600. After receiving the first pressing signal, the controller 600 can analyze the first pressing signal and determine that the item to be refrigerated in the storage drawer 200 is the first type of item.

[0097] Exemplarily, when the storage drawer 200 has multiple storage areas, the user can perform refined storage on the items to be refrigerated of multiple item types 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 type of item and the second type of item, the first type of item can be placed in the first storage area 230, and the second type of item can be placed in the second storage area 240. Then, the user presses the first item type button and the second item type button respectively to generate a first pressing signal and a second pressing signal, and sends the first pressing signal and the second pressing signal to the controller 600. After receiving the first pressing signal and the second pressing signal, the controller 600 can analyze the first pressing signal and the second pressing signal, and determine that the item to be refrigerated in the first storage area 230 is the first type of item, and the item to be refrigerated in the second storage area 240 is the second type of item.

[0098] Exemplarily, the refrigerator may further be provided with a smart button electrically connected to the controller 600. When the smart button is pressed, an automatic start signal is generated. The controller 600 can automatically obtain the type determination information in response to the automatic start signal to automatically identify the item type of the item to be refrigerated. Refer to Figure 9 , the control method of the refrigerator according to the embodiment of the present application may further include the following steps:

[0099] S110. Obtain the automatic start signal generated by the smart button;

[0100] For example, after the user places the item to be refrigerated in the storage drawer 200, the intelligent button can be pressed. The pressed intelligent button generates an automatic recognition signal and sends the automatic recognition signal to the controller 600, and the controller 600 obtains an automatic start signal.

[0101] S120. Generate a first control signal according to the automatic start signal and send the first control signal to the camera. The first control signal is used to control the camera to obtain an image of the item to be refrigerated.

[0102] After receiving the automatic recognition 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 item image, so as to determine the type of the item to be refrigerated according to the item image, and realize the automatic recognition of the item type.

[0103] Exemplarily, after the item to be refrigerated is placed in the storage drawer 200, if the user does not press the corresponding item type button nor the intelligent button, the controller 600 can generate a first control signal after a preset waiting duration to control the camera 710 to obtain an item image, so as to determine the type of the item to be refrigerated. Such a setting can prevent the automatic acquisition of the type of the item to be refrigerated when the user makes a misoperation or has no operation, which is convenient for subsequent targeted preservation of the item to be refrigerated and enhances the preservation effect of the item to be refrigerated.

[0104] S200. Control the magnetic field generating device to generate a magnetic field to reach the target magnetic field intensity according to the item type.

[0105] After determining the item type, the controller 600 can control the magnetic field generating device 500 to generate a magnetic field to reach the target magnetic field intensity according to the item type, so as to perform targeted preservation on the item to be refrigerated, prevent the problem of spoilage or insufficient preservation of the item to be refrigerated caused by too high or too low magnetic field intensity, and improve the preservation effect of the item to be refrigerated.

[0106] Exemplarily, the controller 600 can obtain a first preset correspondence, which includes multiple item types and the magnetic field intensity corresponding to each item type. The controller 600 can determine the target magnetic field intensity in the first preset correspondence according to the item type. Exemplarily, the refrigerator can further 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 intensity of the magnetic field generating device 500 can be conveniently determined according to the item type, so as to perform targeted preservation on the item to be refrigerated, prevent the problem of spoilage or insufficient preservation of the item to be refrigerated caused by too high or too low magnetic field intensity, and improve the preservation effect of the item to be refrigerated. The first preset correspondence can be as shown in Table 1.

[0107] For example, when the controller 600 determines that the type of the item to be refrigerated is a first type of item such as fruit, the target magnetic field intensity is determined to be 6 mT to 10 mT in the second preset relationship shown in Table 1, and then the controller controls the magnetic field generating device 500 to generate a magnetic field with a magnetic field intensity reaching 6 mT to 10 mT.

[0108] Table 1

[0109] Item type Magnetic field strength (mT) The first type of items such as fruits 6～10 The second type of items such as vegetables 3～6 The third type of items such as fresh meat 1～3 The fourth type of items such as fungi 3～6

[0110] In some possible implementations of the embodiments of the present application, the controller 600 may further control the refrigeration system 300 to provide cooling capacity according to the type of the item, so that the target refrigeration temperature is reached inside the storage drawer 200. With such a setting, the refrigeration temperature of the item to be refrigerated can be adjusted according to the type of the item, so that the item to be refrigerated is at a refrigeration temperature suitable for storage, and the freshness preservation period of the item to be refrigerated is extended.

[0111] Reference Figure 10 , the control method of the embodiments of the present application may further include the following steps:

[0112] S210. Determine the target refrigeration temperature according to the type of the item;

[0113] Exemplarily, the controller 600 may obtain a second preset correspondence relationship, which includes multiple types of items and the refrigeration temperature corresponding to each type of item. The controller 600 may determine the target refrigeration temperature in the second preset correspondence relationship according to the type of the item. The second preset correspondence relationship may be stored in the memory in the form of a database. The second preset correspondence relationship may be as shown in Table 2.

[0114] Table 2

[0115]

[0116]

[0117] For example, when the item to be refrigerated is a first type of item such as fruit and a second type of item such as vegetables, the target refrigeration temperature may be 2°C to 6°C. When the item to be refrigerated is a third type of item such as fresh meat, the target refrigeration temperature may be -5°C to 0°C.

[0118] S220. Control the refrigeration system so that the refrigeration temperature inside the storage drawer reaches the target refrigeration temperature.

[0119] Exemplarily, the controller 600 may control the start-stop time of the compressor 310 in the refrigeration system 300, so that the refrigeration temperature inside the storage drawer 200 reaches the target refrigeration temperature.

[0120] Exemplarily, when the storage drawer 200 has multiple storage areas, the magnetic field generating device 500 includes multiple magnetic field generating units 510. One magnetic field generating unit 510 can 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 can determine the type of the 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 intensity according to the type of the items to be refrigerated in each storage area. With such an arrangement, items to be refrigerated of different types can be placed in the same storage drawer 200, improving the flexibility of storing items to be refrigerated; and it can enable the items to be refrigerated of different types in different storage areas to be preserved under the action of magnetic fields of different magnetic field intensities, improving the difference in preservation conditions for items to be refrigerated of different types, preventing items to be refrigerated of different types in the same storage drawer 200 from being stored under the same conditions, having a strong preservation effect on each type of items to be refrigerated, and enhancing the user experience.

[0121] S300. Control the weight measuring device to obtain the weight of the item to be refrigerated, determine the target action duration according to the item weight, and control the magnetic field generating device to generate a magnetic field for the target action duration.

[0122] The controller 600 can control the weight sensor to obtain the weight of the item to be refrigerated placed in the storage drawer 200, then determine the target action duration according to the item weight, and control the magnetic field generating device 500 to generate a magnetic field for the target action duration, so as to adjust the action duration of the magnetic field generated by the magnetic field generating device 500 according to the weight of the item to be refrigerated, prevent the magnetic field generating device 500 from continuously working during the opening duration of the magnetic field preservation function, reduce the energy consumed by the magnetic field generating device 500, thereby reducing the energy consumption of the refrigerator and enhancing customer satisfaction.

[0123] Exemplarily, the controller 600 can obtain a third preset correspondence, which includes multiple weight ranges and the action duration corresponding to each weight range. The controller 600 can determine the target action duration in the third preset correspondence according to the item weight. 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 duration of the magnetic field generating device 500 can be conveniently determined according to the item type for targeted preservation of the items to be refrigerated, preventing problems such as spoilage or insufficient preservation of the items to be refrigerated caused by too high or too low magnetic field intensity, and enhancing the preservation effect on the items to be refrigerated. The third preset correspondence can be as shown in Table 3.

[0124] Table 3

[0125]

[0126]

[0127] For example, when the weight of the item to be refrigerated is 1500 g and it is within the weight range of 1000 g < W ≤ 2000 g, the target action duration is determined to be 2 h.

[0128] Exemplarily, when the storage drawer 200 is a sealed drawer, the controller 600 can also determine whether the item weight is within a preset weight range. If the item weight is within the preset weight range, the controller 600 determines that the target action duration is 0. If the item weight exceeds the upper limit value of the preset weight range, the controller 600 determines that the target action duration is greater than 0. For example, the preset weight range can be 0 g ≤ W ≤ 200 g. When the weight of the item 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, so 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 multiple preset fresh-keeping cycles. Among them, the preset fresh-keeping cycle includes a start section and a stop section. In the start section, the controller 600 controls the magnetic field generating device 500 to generate a magnetic field, and the duration of the start section is the target action duration. In the stop section, the controller 600 controls the magnetic field generating device 500 to stop generating a magnetic field. With such a setting, the magnetic field generating device 500 can be controlled to perform multiple magnetic field fresh-keeping actions on the item to be refrigerated, so as to further enhance the fresh-keeping effect on the item to be refrigerated and extend the fresh-keeping period of the item to be refrigerated.

[0130] Exemplarily, the preset fresh-keeping start cycle can be an integer multiple of the preset fresh-keeping cycle. For example, the preset fresh-keeping start cycle can be 24 h and the preset fresh-keeping cycle can be 8 h. With such a setting, multiple complete preset fresh-keeping cycles can be realized within the preset fresh-keeping start cycle to ensure the fresh-keeping effect of the item to be refrigerated. The durations of the start section and the stop section of the preset fresh-keeping cycle can be as shown in Table 4.

[0131] Table 4

[0132]

[0133]

[0134] For example, if the weight of the item to be refrigerated is 1500g, which is within the weight range of 1000g < W ≤ 2000g, the preset fresh-keeping cycle is determined to have an on-period of 2 hours and a off-period of 4 hours. The controller 600 controls the magnetic field generating device 500 to generate a magnetic field for 2 hours and then to stop generating the magnetic field for 6 hours. The controller 600 then controls the magnetic field generating device 500 to generate a magnetic field for 2 hours and then to stop generating the magnetic field for 6 hours, until the magnetic field generating device 500 completes 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 provided 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 achieve the corresponding target action time. With such a setting, different types of items to be refrigerated in different storage areas can be kept fresh under the action of magnetic fields with different target action times, thereby improving the difference in the fresh-keeping conditions of different types of items to be refrigerated, preventing different types of items to be refrigerated in the same storage drawer 200 from being stored under the same conditions, and having a strong fresh-keeping effect on each type of items to be refrigerated, thereby improving the user experience.

[0136] The control method of the embodiment of the present application can also implement a food management function. For example, when a user places an item to be refrigerated in the storage drawer 200, the camera 710 can obtain 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 item to be refrigerated based on the item image of the item to be refrigerated, and obtain the shelf life data of the item 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 exceeding the expiration date and deteriorating, thereby improving the user experience.

[0137] An embodiment of the present application also provides 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] An embodiment of the present application further provides a program product, which includes execution instructions stored in a readable storage medium. At least one control module of the display device can read the execution instructions from the readable storage medium, and the execution of the execution instructions by at least one control module enables the display device to implement the handwriting erasure method provided by the above various embodiments.
