[0002] The embodiments of the present application relate to the technical field of household appliances, and more specifically, to a refrigerator and a control method thereof. Background Art

[0003] A refrigerator is a refrigeration device that is kept at a constant low temperature. A storage drawer is usually provided inside the refrigerator to accommodate items to be refrigerated, so as to enhance the freshness of the items to be refrigerated.

[0004] To extend the shelf life of refrigerated items, refrigerators are also equipped with a magnetic field preservation function. The refrigerator is equipped with a magnetic field generator that generates a magnetic field that acts on the refrigerated items stored in a storage drawer to preserve their freshness.

[0005] However, the refrigerators equipped with magnetic field preservation function in the related art have high energy consumption, which reduces customer satisfaction. Summary of the Invention

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

[0008] A box body having a refrigeration compartment;

[0009] A storage drawer, which is arranged in the refrigeration room and is used to accommodate items to be refrigerated;

[0010] a refrigeration system disposed in the box and configured to provide cooling;

[0011] a magnetic field generating device configured to generate a magnetic field and cause the magnetic field to act on the items to be refrigerated, so as to keep the items to be refrigerated fresh;

[0012] an information acquisition device configured to acquire information determining the type of the article to be refrigerated;

[0013] a weight measuring device configured to measure the weight of the item to be refrigerated;

[0014] a controller electrically connected with the magnetic field generating device, the information acquisition device and the weight measuring device, configured to determine the type of the to-be-refrigerated article according to the type determination information, and control the magnetic field generating device to generate a magnetic field to reach a target magnetic field strength according to the type of the to-be-refrigerated article; and configured to acquire the weight of the article, determine a target action duration according to the weight of the article, and control the magnetic field generating device to generate a magnetic field to reach the target action duration.

[0015] The refrigerator of the embodiments 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 the to-be-refrigerated article, so as to preserve the to-be-refrigerated article according to the type, thereby realizing the function of fine preservation and enhancing the preservation effect of the to-be-refrigerated article. The refrigerator can also determine a target action duration according to the weight of the article, and control the magnetic field generating device to generate a magnetic field to reach the target action duration, so as to adjust the action duration of the magnetic field generated by the magnetic field generating device according to the weight of the article, to prevent the magnetic field generating device from continuously working within the starting duration of the magnetic field preservation function, thereby reducing the energy consumed by the magnetic field generating device, lowering the energy consumption of the refrigerator, and improving customer satisfaction.

[0016] In some embodiments of the present application, the controller is further configured to acquire a third preset correspondence relationship, the third preset correspondence relationship including a plurality of weight ranges and an action duration corresponding to each weight range; and determine the target action duration in the third preset correspondence relationship according to the weight of the article.

[0017] In this way, the third preset correspondence relationship can be used to conveniently determine the target action duration of the magnetic field generating device according to the type of the to-be-refrigerated article, so as to preserve the to-be-refrigerated article according to the type, to prevent the to-be-refrigerated article from spoiling or being insufficiently preserved due to excessively high or low magnetic field strength, and to improve the preservation effect of the to-be-refrigerated article.

[0018] 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 preservation periods; wherein the preset preservation period includes an opening segment and a stopping segment, in the opening segment, the controller controls the magnetic field generating device to generate a magnetic field, and the duration of the opening segment is the target action duration; and in the stopping segment, the controller controls the magnetic field generating device to stop generating a magnetic field.

[0019] In this way, the magnetic field generating device can be controlled to perform multiple magnetic field preservation actions on the to-be-refrigerated article, so as to further enhance the preservation effect of the to-be-refrigerated article and prolong the preservation period of the to-be-refrigerated article.

[0020] 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 object is within a preset weight range, and if the weight of the object is within the preset weight range, the controller determines that the target action duration is 0; and if the weight of the object exceeds an upper limit value of the preset weight range, the controller determines that the target action duration is greater than 0.

[0021] In this way, when the weight of the object to be refrigerated is within the preset weight range, it can be considered that the number of objects to be refrigerated in the storage drawer is small or there is no object to be refrigerated. Since the storage drawer is a sealed drawer, the sealed drawer can provide sufficient fresh-keeping conditions, so it is not necessary to start the magnetic field generating device, thereby reducing the energy consumption of the refrigerator and improving the user experience.

[0023] In this way, the camera can automatically acquire the object image of the object to be refrigerated, and the controller can automatically determine the object category according to the object image, thereby realizing automatic identification of the object category, without the need for additional user operations, improving the intelligent level of the refrigerator and the user operation convenience and user experience. By providing a plurality of object category keys, the magnetic field fresh-keeping function can be started based on user operations, thereby enriching the starting mode of the magnetic field fresh-keeping function and improving the user experience.

[0024] In some embodiments of the present application, the controller is further configured to acquire a first preset correspondence relationship, the first preset correspondence relationship including a plurality of object categories and a magnetic field strength corresponding to each object category; and determining the target magnetic field strength in the first preset correspondence relationship according to the object category.

[0025] In this way, by the first preset correspondence relationship, the target magnetic field strength of the magnetic field generating device can be conveniently determined according to the object category, so as to perform targeted fresh-keeping on the object to be refrigerated, thereby preventing the object to be refrigerated from being spoiled or not being fresh-kept enough due to excessively high or low magnetic field strength, and improving the fresh-keeping effect on the object to be refrigerated.

[0026] In some embodiments of the present application, the magnetic field generating device comprises a plurality of magnetic field generating units; the storage drawer is formed with a plurality of storage areas, and one of the magnetic field generating units is correspondingly arranged in each of the storage areas, and the magnetic field generated by the magnetic field generating unit acts on the to-be-cooled articles in the corresponding storage area; the controller is configured to determine the article category of the to-be-cooled articles in each of the storage areas according to the category determination information, and control the corresponding magnetic field generating unit to reach the target magnetic field strength according to the article category of the to-be-cooled articles in each of the storage areas.

[0027] In this way, different article categories of to-be-cooled articles can be placed in the same storage drawer, improving the flexibility of storing to-be-cooled articles; and different article categories of to-be-cooled articles in different storage areas can be preserved under the action of magnetic fields with different magnetic field strengths, improving the difference in preservation conditions of different article categories of to-be-cooled articles, preventing different article categories of to-be-cooled articles in the same storage drawer from being stored under the same conditions, and having a strong preservation effect on each article category of to-be-cooled articles, thereby improving the user experience.

[0028] In some embodiments of the present application, the weight measuring device comprises a plurality of weight measuring units; one of the weight measuring units is correspondingly arranged in each of the storage areas, and the weight measuring unit is configured to measure the article weight of the to-be-cooled articles in the corresponding storage area; the controller is further configured to determine the corresponding target action time according to the article weight of the to-be-cooled articles in each of the storage areas, and control the magnetic field generating unit corresponding to the storage area to generate a magnetic field reaching the corresponding target action time.

[0029] In this way, different article categories of to-be-cooled articles in different storage areas can be preserved under the action of magnetic fields with different target action times, improving the difference in preservation conditions of different article categories of to-be-cooled articles, preventing different article categories of to-be-cooled articles in the same storage drawer from being stored under the same conditions, and having a strong preservation effect on each article category of to-be-cooled articles, thereby improving the user experience.

[0030] In some embodiments of the present application, the controller is further configured to control the refrigeration system to provide cold energy according to the article category, so that the target refrigeration temperature is reached in the storage drawer.

[0031] In this way, the refrigeration temperature of to-be-cooled articles can be adjusted according to the article category, so that the to-be-cooled articles are in a suitable refrigeration temperature for storage, thereby prolonging the preservation period of the to-be-cooled articles.

[0032] In a second aspect, an embodiment of the present application provides a method for controlling a refrigerator, the refrigerator comprising a cabinet, a storage drawer, a refrigeration system, a magnetic field generating device, an information acquisition device, and a weight measuring device, wherein the cabinet is configured with a refrigeration compartment; the storage drawer is disposed in the refrigeration compartment for accommodating items to be refrigerated; the refrigeration system is disposed in the cabinet and is configured to provide cooling for the items to be refrigerated; the magnetic field generating device is configured to generate a magnetic field, and to cause the magnetic field to act on the items to be refrigerated to preserve the freshness of the items to be refrigerated; the information acquisition device is configured to obtain information determining the type of the items to be refrigerated; and the weight measuring device is configured to measure the weight of the items to be refrigerated; the control method comprises:

[0068] For the purpose of making the purposes, embodiments and advantages of the present application clearer, the following will combine the drawings in the exemplary embodiments of the present application to clearly and completely describe the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, not all the embodiments.

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

[0070] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not have to be limited to the clearly listed components, but can include other components not clearly listed or inherent to these products or devices.

[0071] For the refrigerator in the related art, there is a technical problem that the refrigerator configured with the magnetic field preservation function has high energy consumption, which reduces customer satisfaction. The inventor found that the reason is that the magnetic field generating device continuously generates a magnetic field within the opening time of the magnetic field preservation function after the magnetic field preservation function is turned on. The magnetic field generating device consumes more energy. Especially when the number of refrigeration items in the storage drawer is small or there is no refrigeration item, the magnetic field generating device still works continuously within the opening time, resulting in energy waste, thereby causing the refrigerator to have high energy consumption, which reduces customer satisfaction.

[0072] Therefore, the embodiments of the present application provide a refrigerator and a control method thereof. By acquiring the weight of the refrigeration items in the storage drawer, the action time of the magnetic field generated by the magnetic field generating device is adjusted according to the weight of the items, so as to prevent the magnetic field generating device from working continuously within the opening 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.

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

[0074] Reference Fig. 1 The refrigerator provided by the embodiments of the present application can include a cabinet 100 configured with a refrigeration compartment 110. Exemplarily, the cabinet 100 can 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 can be configured with the refrigeration compartment 110 for accommodating food and other items. The refrigeration compartment 110 can have a taking and placing opening through which the items can be taken out or placed into the refrigeration compartment 110.

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

[0076] Exemplarily, the sealed drawer can include a drawer body 210 and a cover body 220, the drawer body 210 is slidable relative to the inner liner 130 along the vertical extension direction of the cabinet 100 to be pulled out of or pushed into the refrigeration compartment 110. The cover body 220 is arranged in the refrigeration compartment 110 and connected with the inner liner 130 to be separated from the drawer body 210 when the drawer body 210 is pulled out of the refrigeration compartment 110, and arranged on the drawer body 210 and sealedly connected with the drawer body 210 when the drawer body 210 is pushed into the refrigeration compartment 110.

[0077] For example, refer to Fig. 3 、 Fig. 4 、 Fig. 5 and Fig. 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, which 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) located within the housing 100. The refrigeration system 300 is configured to provide cooling capacity to cool the items to be refrigerated. For example, the refrigeration system 300 may include a compressor 310, a condenser, a capillary tube, and an evaporator. The compressor 310 compresses refrigerant vapor to generate high-temperature, high-pressure steam, which is then transported to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor to generate high-temperature, low-pressure refrigerant liquid, which is then transported to the capillary tube. The capillary tube reduces the pressure of the refrigerant liquid, converting the high-pressure, low-temperature liquid into a low-pressure, low-temperature refrigerant, which is then transported to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant and causes it to boil under isobaric conditions. This absorbs heat and vaporizes to generate cooling capacity, thereby lowering the temperature within the refrigeration compartment 110 and thereby cooling the items to be refrigerated.

[0079] The refrigerator may further include an air guide 400 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, to refrigerate the items to be refrigerated. Fig. 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 container 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 connected to the first air duct, and the first air outlet 411 is opposite the storage drawer 200. The first air duct assembly 410 may also be provided with a driving fan. When the driving fan rotates, cooling air is generated. The cooling air carries the cooling energy provided by the refrigeration system 300 and flows out of the first air outlet 411 and blows toward the storage drawer 200, thereby cooling the items to be refrigerated located in the storage drawer 200.

[0080] In some possible implementation manners of the embodiments of the present application, the first air outlet 411 can be opposite to a top opening of the storage drawer 200, and the air flowing out of the first air outlet 411 can directly blow to the to-be-cooled articles. In another possible implementation manner of the embodiments of the present application, the air guide device 400 further comprises a second air duct assembly 420, which is arranged between the cover 220 and the drawer body 210 and connected with the first air duct assembly 410. The second air duct assembly 420 is formed with a second air duct, and the second air duct is connected with the first air duct through the first air outlet 411. The second air duct assembly 420 can be further provided with a second air outlet connected to the second air duct on the side facing the drawer body 210. The refrigeration air generated by the driving fan can enter the second air duct from the first air duct, and flow out of the second air outlet to blow to the to-be-cooled articles in the storage drawer 200.

[0081] The refrigerator can further comprise a magnetic field generating device 500 configured to generate a magnetic field and act on the to-be-cooled articles. The magnetic field acting on the to-be-cooled articles can affect the expression of genes, change the permeability of cell membranes, and reduce the metabolic rate of the to-be-cooled articles. The magnetic field can also form more hydrogen bonds, reduce weight loss and juice loss, and delay tissue structure softening. The magnetic field can also eliminate hydrogen peroxide and superoxide free radicals in the to-be-cooled articles, protect the tissue cells of the to-be-cooled articles from oxidative damage, and preserve the to-be-cooled articles. In addition, the strong penetration of the magnetic field can effectively penetrate various packaging materials, and when the user uses the packaging materials to wrap the to-be-cooled articles before storing them in the refrigerator, the to-be-cooled articles still have good preservation effect.

[0082] For example, the magnetic field generating device 500 can comprise at least one magnetic field generating unit 510 capable of generating a magnetic field, for example, an electromagnetic coil or a permanent magnet. Referring to Fig. 2 , the magnetic field generating unit 510 can comprise two magnetic assemblies 511, which can be mounted on opposite sides of the storage drawer 200. For example, one of the magnetic assemblies 511 can be arranged between the cover 220 and the first air duct assembly 410, and the other magnetic assembly 511 can be arranged between the drawer body 210 and the bottom plate 150. The magnetic assembly 511 can be connected with the storage drawer 200 by bolts.

[0083] For example, referring to Fig. 6 When the storage drawer 200 has a plurality of storage areas, the magnetic field generating unit 510 can also have a plurality of magnetic field generating units 510. Each storage area is provided with a magnetic field generating unit 510 corresponding to the to-be-cooled articles in the corresponding storage area.

[0084] The refrigerator of the embodiment of the present application can further comprise an information acquisition device 700 configured to acquire category determination information of the refrigeration object, the category determination information being used to determine the object category of the refrigeration object. For example, the information acquisition device 700 can be a camera 710 configured to acquire an object image of the refrigeration object, the object image being the category determination information. The object category of the refrigeration object can be determined according to the object image. The camera 710 can be installed on the top surface inside the storage drawer 200. For example, the top surface inside the storage drawer 200 can further be provided with a rotating device connected with the camera 710 and configured to drive the camera 710 to rotate. For example, the rotating device can drive the camera 710 to rotate in the horizontal direction within an angle range of 0-360° and in the vertical direction within an angle range of 0-90°.

[0085] For example, the information acquisition device 700 can also be an object category button configured to generate a pressing signal when pressed, the pressing signal being the category determination information. The object category of the refrigeration object can be determined according to the pressing signal. For example, the object category button can be a physical button. The object category button can also be a touch button provided on a touch screen 720. The touch screen 720 can be provided on the cover plate 140 inside the refrigeration compartment 110.

[0086] The refrigerator of the embodiment of the present application further comprises a weight measurement device 800 configured to measure the object weight of the refrigeration object. For example, the weight measurement device 800 can comprise at least one weight measurement unit for weight measurement, the weight measurement unit can be a weight sensor, and the weight sensor can be installed on the bottom surface inside the storage drawer 200. For example, when the storage drawer 200 has a plurality of storage areas, the weight measurement device 800 can also have a plurality of weight measurement units. Each storage area is provided with a corresponding weight measurement unit configured to measure the object weight of the refrigeration object in the corresponding storage area.

[0087] Reference Fig. 7The refrigerator provided in the embodiments of the present application further comprises a controller 600, which can be electrically connected with 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 refrigeration object according to the type determination information, and control the magnetic field generating device 500 to generate a magnetic field reaching a target magnetic field strength according to the type of the refrigeration object, so as to perform targeted preservation on the refrigeration object according to the type of the refrigeration object, thereby realizing the function of fine preservation and enhancing the preservation effect of the refrigeration object. The controller 600 is further configured to acquire the weight of the refrigeration object, determine a target action time according to the weight of the refrigeration object, and control the magnetic field generating device 500 to generate a magnetic field reaching the target action time, so as to adjust the action time of the magnetic field generated by the magnetic field generating device 500 according to the weight of the refrigeration object, to prevent the magnetic field generating device 500 from continuously working within the starting time of the magnetic field preservation function, thereby reducing the energy consumed by the magnetic field generating device 500, reducing the energy consumption of the refrigerator, and improving customer satisfaction.

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

[0089] The embodiments of the present application further provide a control method of a refrigerator, which is used to control the refrigerator. Fig. 8 The control method can comprise the following steps:

[0090] S100, acquiring type determination information of a refrigeration object generated by an information acquisition device, and determining the type of the refrigeration object according to the type determination information.

[0091] The controller 600 can automatically acquire the type determination information of the refrigeration object generated by the information acquisition device 700.

[0092] Exemplarily, the information acquisition device 700 can be a camera 710 electrically connected with the controller 600. The controller 600 can generate a first control signal according to a preset preservation starting period, and send the first control signal to the camera 710. For example, the preset preservation starting period can be 24 hours. The camera 710 can shoot the refrigeration object in response to the first control signal to acquire an object image of the refrigeration object, and the object image is the type determination information. The controller 600 can determine the type of the refrigeration object according to the object image. For example, the controller 600 can analyze the object image to obtain a type feature value of the refrigeration object, input the type feature value into a pre-trained object type recognition model, and thereby obtain the type of the refrigeration object. The object image of the refrigeration object can be automatically acquired by the camera 710, and the controller 600 can automatically determine the type of the refrigeration object according to the object image, thereby realizing automatic identification of the type of the refrigeration object, without the need for additional operation of the user, improving the intelligent degree of the refrigerator, and improving the convenience of operation of the user and the experience effect of the user.

[0093] When the storage drawer 200 has multiple storage areas, the camera 710 can capture images of the refrigeration-required items in the multiple storage areas in the storage drawer 200 to obtain the item images of the refrigeration-required items in the multiple storage areas. For example, the camera 710 can have a large enough field of view to clearly image the refrigeration-required items in the multiple storage areas in the same image. When the controller 600 analyzes the item images, the item categories of the refrigeration-required items in the multiple storage areas can be obtained at the same time.

[0094] Alternatively, the controller 600 can also generate a rotation driving signal and send the rotation driving signal to the rotating device. The rotating device drives the camera 710 to rotate in response to the rotation driving signal to capture images of the refrigeration-required items in each storage area respectively, thereby obtaining the item images of the refrigeration-required items in each storage area. The controller 600 can analyze the item images of the refrigeration-required items in each storage area respectively to obtain the item categories of the refrigeration-required items in the multiple storage areas.

[0095] The controller 600 can also obtain the category determination information in response to the operation of the user.

[0096] Exemplarily, the information acquisition device 700 can also be multiple item category keys electrically connected to the controller 600. The item category keys generate a pressing signal when pressed. The controller 600 can determine the item category according to the pressing signal. After the user places the refrigeration-required items in the storage drawer 200, the user can press the item category key corresponding to the refrigeration-required items 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 item category of the refrigeration-required items. By providing multiple item category keys, the magnetic field preservation function can be started based on the operation of the user, the starting mode of the magnetic field preservation function is enriched, and the user experience is improved.

[0097] Exemplarily, the plurality of article category keys can include a first article category key, a second article category key, a third article category key, and a fourth article category key. The first article category key corresponds to a first type of article, and the first article category key generates a first pressing signal when pressed. The second article category key corresponds to a second type of article, and the second article category key generates a second pressing signal when pressed. The third article category key corresponds to a third type of article, and the third article category key generates a third pressing signal when pressed. The fourth article category key corresponds to a fourth type of article, and the fourth article category key generates a fourth pressing signal when pressed. For example, when the user needs to refrigerate the first type of article, the first type of article can be placed in the storage drawer 200. Then, the user can press the first article category key to generate the 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 article to be refrigerated in the storage drawer 200 is the first type of article.

[0098] Exemplarily, when the storage drawer 200 has a plurality of storage areas, the user can simultaneously store a plurality of types of articles to be refrigerated in the storage drawer 200. For example, the plurality of 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. When the user needs to refrigerate the first type of article and the second type of article, the first type of article can be placed in the first storage area 230 and the second type of article can be placed in the second storage area 240. Then, the user can press the first article category key and the second article category key respectively to generate the first pressing signal and the second pressing signal, and send 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, determine that the article to be refrigerated in the first storage area 230 is the first type of article, and determine that the article to be refrigerated in the second storage area 240 is the second type of article.

[0099] Exemplarily, the refrigerator can also be provided with a smart key electrically connected to the controller 600, and the smart key is pressed to automatically generate a start signal. The controller 600 can automatically obtain category determination information in response to the automatic start signal to automatically identify the article category of the article to be refrigerated. Referring to Fig. 9 The control method of the refrigerator of the embodiment of the present application can further include the following steps:

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

[0101] For example, after placing items to be refrigerated in the storage drawer 200, the user can press the smart button. The pressed smart button generates an automatic identification signal and sends the automatic identification signal to the controller 600, which then 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 a camera, where the first control signal is used to control the camera to obtain an image of the item 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 based on the image of the object, thereby realizing automatic identification of the type of object.

[0104] For example, after placing an item to be refrigerated in storage drawer 200, if the user does not press the corresponding item type button or the smart button, controller 600 may generate a first control signal after a preset waiting time to control camera 710 to capture an image of the item, thereby determining the type of the item to be refrigerated. This configuration prevents user error or automatic acquisition of the item type in the absence of any operation, thereby facilitating subsequent targeted preservation of the refrigerated items and enhancing the preservation effect of the refrigerated items.

[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 being spoiled or insufficiently preserved 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 too 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 category of the refrigeration target article is the first category of fruits and the like, and the target magnetic field strength is determined to be 6 mT-10 mT in the second preset relationship shown in Table 1, the magnetic field generating device 500 is controlled to generate a magnetic field with a magnetic field strength of 6 mT-10 mT.

[0109] Table 1

[0110] Item category Magnetic field strength (mT) Fruit and the like as first category items 6～10 Vegetables and the like as second category items 3～6 Raw meat and the like as third category items 1～3 Mushrooms and the like as fourth category items 3～6

[0111] In some possible manners of the embodiments of the present application, the controller 600 can also control the refrigeration system 300 to provide a cooling capacity according to the category of the article, so that the target refrigeration temperature is reached in the storage drawer 200. In this way, the refrigeration temperature of the refrigeration target article can be adjusted according to the category of the article, so that the refrigeration target article is in a suitable refrigeration temperature for storage, and the shelf life of the refrigeration target article is prolonged.

[0112] Reference Fig. 10 The control method of the embodiments of the present application can further include the following steps:

[0113] S210, determining a target refrigeration temperature according to the category of the article;

[0114] Exemplarily, the controller 600 can obtain a second preset corresponding relationship, which includes a plurality of categories of articles and a refrigeration temperature corresponding to each category of article. The controller 600 can determine a target refrigeration temperature in the second preset corresponding relationship according to the category of the article. The second preset corresponding relationship can be stored in the storage in the form of a database. The second preset corresponding relationship can be as shown in Table 2.

[0115] Table 2

[0116]

[0117]

[0118] For example, when the refrigeration target article is the first category of fruits and the like and the second category of vegetables and the like, the target refrigeration temperature can be 2℃-6℃. When the refrigeration target article is the third category of fresh meat and the like, the target refrigeration temperature can be -5℃-0℃.

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

[0120] Exemplarily, the controller 600 can 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 a plurality of storage areas, the magnetic field generating device 500 comprises a plurality of 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 to-be-cooled articles in the corresponding storage area. The controller 600 can determine the article category of the to-be-cooled articles in each storage area according to the category determination information, and control the corresponding magnetic field generating unit 510 to reach the target magnetic field strength according to the article category of the to-be-cooled articles in each storage area. In this way, to-be-cooled articles of different article categories can be placed in the same storage drawer 200, improving the flexibility of storing to-be-cooled articles; and to-be-cooled articles of different article categories in different storage areas can be preserved under the action of magnetic fields of different magnetic field strengths, improving the difference in preservation conditions of to-be-cooled articles of different article categories, preventing to-be-cooled articles of different article categories in the same storage drawer 200 from being stored under the same conditions, and having a strong preservation effect on to-be-cooled articles of each article category, thereby improving the user experience.

[0122] S300, controlling the weight measuring device to obtain the article weight of the to-be-cooled articles, determining the target action time according to the article weight, and controlling the magnetic field generating device to generate a magnetic field to reach the target action time.

[0123] The controller 600 can control the weight sensor to obtain the article weight of the to-be-cooled articles accommodated in the storage drawer 200, then determine the target action time according to the article weight, and control the magnetic field generating device 500 to generate a magnetic field to reach the target action time, so as to adjust the action time of the magnetic field generated by the magnetic field generating device 500 according to the weight of the to-be-cooled articles, prevent the magnetic field generating device 500 from continuously working within the turning-on time 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.

[0124] Exemplarily, the controller 600 can obtain a third preset correspondence relationship, and the third preset correspondence relationship comprises a plurality of weight ranges and an action time corresponding to each weight range. The controller 600 can determine the target action time in the third preset correspondence relationship according to the article weight. Exemplarily, the third preset correspondence relationship can be stored in the storage in the form of a database. Through the third preset correspondence relationship, the target action time of the magnetic field generating device 500 can be conveniently determined according to the article category to preserve the to-be-cooled articles, prevent the to-be-cooled articles from being spoiled or not preserved enough due to the magnetic field strength being too high or too low, and improve the preservation effect of the to-be-cooled articles. The third preset correspondence relationship can be as shown in Table Three.

[0125] Table Three

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

[0127] For example, when the weight of the to-be-cooled goods is 1500g, and the weight is in the range of 1000g < W≤2000g, the target action duration is determined to be 2h.

[0128] For example, when the storage drawer 200 is a sealed drawer, the controller 600 can further determine whether the weight of the goods is in a preset weight range. If the weight of the goods is in the preset weight range, the controller 600 determines that the target action duration is 0. If the weight of the goods exceeds the upper limit 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 0g≤W≤200g. When the weight of the to-be-cooled goods is in the preset weight range, it can be considered that the number of to-be-cooled goods in the storage drawer 200 is small or there is no to-be-cooled goods. Since the storage drawer 200 is a sealed drawer, the sealed drawer can provide sufficient fresh-keeping conditions, so it is not necessary to start the magnetic field generating device 500, thereby reducing the energy consumption of the refrigerator and improving the user experience.

[0129] For example, the controller 600 can further control the magnetic field generating device 500 to generate a magnetic field according to a plurality of preset fresh-keeping periods. The preset fresh-keeping period includes an on period and an off period. In the on period, the controller 600 controls the magnetic field generating device 500 to generate a magnetic field, and the length of the on period is the target action duration. In the off period, the controller 600 controls the magnetic field generating device 500 to stop generating a magnetic field. In this way, the magnetic field generating device 500 can be controlled to perform multiple magnetic field fresh-keeping actions on the to-be-cooled goods, so as to further enhance the fresh-keeping effect on the to-be-cooled goods and prolong the fresh-keeping period of the to-be-cooled goods.

[0130] For example, the preset fresh-keeping start period can be an integer multiple of the preset fresh-keeping period. For example, the preset fresh-keeping start period can be 24h, and the preset fresh-keeping period can be 8h. In this way, multiple complete preset fresh-keeping periods can be implemented within the preset fresh-keeping start period, so as to ensure the fresh-keeping effect of the to-be-cooled goods. The lengths of the on period and the off period of the preset fresh-keeping period can be as shown in Table Four.

[0131] Table Four

[0132]

[0133]

[0134] For example, when the weight of the to-be-cooled goods is 1500 g, and the weight range is 1000 g < W < 2000 g, the starting period of the preset preservation period is determined as 2 h, and the stopping period is determined as 4 h. The controller 600 controls the magnetic field generating device 500 to generate a magnetic field for 2 h and stop generating a magnetic field for 6 h. The controller 600 controls the magnetic field generating device 500 to generate a magnetic field for 2 h and stop generating a magnetic field for 6 h again, until the controller 600 controls the magnetic field generating device 500 to complete three preset preservation periods.

[0135] For example, the weight measuring device 800 can include a plurality of weight measuring units. Each weight measuring unit is arranged in a corresponding storage area and is configured to measure the weight of the to-be-cooled goods in the corresponding storage area. The controller 600 can also determine the target action time for each storage area according to the weight of the to-be-cooled goods in the corresponding storage area, and control the magnetic field generating unit 510 corresponding to the storage area to generate a magnetic field for the target action time. In this way, the to-be-cooled goods of different types in different storage areas can be preserved under the action of a magnetic field with different target action times, which improves the difference in preservation conditions of to-be-cooled goods of different types, prevents to-be-cooled goods of different types in the same storage drawer 200 from being stored under the same conditions, and has a strong preservation effect on to-be-cooled goods of each type, thereby improving the user experience.

[0136] The control method of the embodiment of the present application can also realize the food material management function. For example, when the user places the to-be-cooled goods in the storage drawer 200, the camera 710 can obtain the images of the to-be-cooled goods in the plurality of different storage areas in the storage drawer 200. The controller 600 can determine the storage days of the to-be-cooled goods according to the images of the to-be-cooled goods, and obtain the shelf life data of the to-be-cooled goods in the storage, 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 of the refrigerator to prevent the to-be-cooled goods in the storage drawer 200 from deteriorating beyond the shelf life, thereby improving the user experience.

[0137] The embodiment of the present application also provides a computer readable storage medium, which can include a U disk, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, and various storage program codes. Specifically, the computer readable storage medium stores program instructions, which are used for the method in the above embodiment.

[0138] The embodiments of the present application further provide a program product including 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 at least one control module executes the execution instructions to enable the display device to implement the handwriting erasing method provided by the various embodiments described above.
