[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0040] The present application provides a fresh-keeping space, which is applied to a refrigerator and is used to store items with specific requirements for temperature, humidity, etc. or items with high fresh-keeping requirements. The refrigerator may be a single-door, double-door, side-by-side, French, cross-type refrigerator or other types of refrigerators. For example, please refer to Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the structure of the fresh-keeping space provided in the embodiment of the present application. Figure 2 The fresh-keeping compartment 100 includes a compartment body 110 , a magnetic field generating assembly 120 and a demagnetizing reflector 130 .

[0041] Among them, the compartment body 110 has a first side wall 1121 and a second side wall 1111 that are relatively spaced apart, and a fresh-keeping space 1112 is formed between the first side wall 1121 and the second side wall 1111; the magnetic field generating assembly 120 is installed on the first side wall 1121, and is used to apply a magnetic field to the fresh-keeping space 1112; the demagnetization reflection plate 130 is arranged on the surface of the second side wall 1111 located in the fresh-keeping space 1112, and is used to reflect the magnetic field.

[0042] It can be understood that due to the characteristics of the magnetic field distribution, inside the fresh-keeping space 1112 , the magnetic field directly generated by the magnetic field generating assembly 120 gradually decreases in intensity from the area close to the first side wall 1121 to the area close to the second side wall 1111 .

[0043] In actual application, by adding a demagnetizing reflective plate 130 to the second side wall 1111, part of the electromagnetic waves emitted by the magnetic field generating assembly 120 will be reflected by the demagnetizing reflective plate 130, thereby forming a reflected magnetic field in the fresh-keeping space 1112, so that the magnetic field strength of the area inside the fresh-keeping space 1112 close to the second side wall 1111 is increased, and the uniformity of the magnetic field in each area of ​​the fresh-keeping space 1112 is increased, thereby improving the fresh-keeping performance of the fresh-keeping compartment 100.

[0044] Preferably, the material of the demagnetizing reflective plate 130 is stainless iron. It should be noted that stainless iron first has the performance of being able to reflect magnetic fields, and secondly, the performance of stainless iron also includes high temperature resistance, corrosion resistance, oxidation resistance, and strong thermal conductivity. In this way, on the one hand, a reflected magnetic field is formed in the fresh-keeping space 1112 by the demagnetizing reflective plate 130, so that the uniformity of the magnetic field in each area of ​​the fresh-keeping space 1112 is increased; on the other hand, based on the high thermal conductivity of the demagnetizing reflective plate 130, the uniformity of the temperature in each area of ​​the fresh-keeping space 1112 can also be improved, so that the fresh-keeping performance of the fresh-keeping chamber 100 is better.

[0045] In some embodiments, the demagnetizing reflective plate 130 includes a first surface 131 facing the first side wall 1121, and the first surface 131 is provided with a food contact material layer (not shown in the figure), and the food contact material layer is suitable for direct contact with the items in the fresh-keeping space. Preferably, each surface of the demagnetizing reflective plate 130 is covered with a food contact material layer, which on the one hand improves food safety, and on the other hand prevents the demagnetizing reflective plate 130 from being corroded. Among them, the food contact material layer can be a food-grade plastic layer, a glass layer or a ceramic layer, etc. In addition, the demagnetizing reflective plate 130 made of stainless iron material itself is not easy to rust, and is also suitable for contact with food.

[0046] In some embodiments, the compartment body 110 further includes a circumferential side wall 1114 disposed around the edge of the second side wall 1111, the first side wall 1121, the second side wall 1111 and the circumferential side wall 1114 enclose a fresh-keeping space 1112, and the demagnetization reflector 130 is further disposed on the circumferential side wall 1114 and located on the inner surface of the fresh-keeping space 1112. In this way, the multiple side walls of the compartment body 110 forming the fresh-keeping space 1112 can reflect the magnetic field, thereby ensuring that the magnetic field is evenly distributed in each area of ​​the fresh-keeping space 1112, improving the uniformity of the magnetic field in the fresh-keeping space 1112, and improving the fresh-keeping effect of the fresh-keeping compartment 100.

[0047] It is understandable that for items with high preservation requirements such as food that has just been placed in the fresh-keeping space 1112, food with a close expiration date, etc., a stronger magnetic field may need to be applied to achieve the effect of extending the shelf life. However, due to the limited space in the fresh-keeping space 1112, if the user wants to place the above-mentioned items with high preservation requirements in an area with a strong magnetic field, such as the middle area, it may be necessary to rearrange at least part of the items in the fresh-keeping space 1112 to achieve this, wasting the user's time and energy and affecting the user's experience.

[0048] Based on the above problems, this application provides an embodiment, please refer to Figure 3 , Figure 3Another cross-sectional view of the fresh-keeping compartment provided in an embodiment of the present application. The magnetic field generating assembly 120 is slidably connected to the first side wall 1121, and the fresh-keeping compartment 100 further includes a mechanical arm 140, which is mounted on the compartment body 110 and connected to the magnetic field generating assembly 120, and the mechanical movement of the mechanical arm 140 drives the magnetic field generating assembly 120 to slide on the first side wall 1121.

[0049] In practical applications, the magnetic field generating assembly 120 can be driven to slide to a position corresponding to items with higher preservation requirements by manipulating the mechanical arm, so as to apply a stronger magnetic field to the items with higher preservation requirements and extend the shelf life of the items. Compared with the user rearranging the items in the preservation space, the present application directly adjusts the relative position of the magnetic field generating assembly 120 on the first side wall 1121 through the mechanical arm, which is convenient and effortless to operate.

[0050] Furthermore, in order to improve the intelligence level of the fresh-keeping chamber 100, a detection device (not shown in the figure) can also be provided. The detection device is arranged in the fresh-keeping space 1112 and is used to detect the first position of the target item in the fresh-keeping space 1112; the mechanical arm 140 performs mechanical movement based on the first position to drive the magnetic field generating component 120 to slide to a first relative position corresponding to the first position, thereby preserving the target item.

[0051] It should be noted that the target items may include items that have just been placed in the fresh-keeping space 1112, items that have been placed in the fresh-keeping space 1112 for a long time, and items that are nearing their expiration date. The detection device may include at least one of an image acquisition device, an odor detection device, and an infrared device. When the magnetic field generating component 120 is located at the first relative position, it can provide a stronger magnetic field to the target item located at the first position relative to other positions, and the first relative position needs to be determined according to the magnetic field distribution characteristics of the magnetic field generated by the magnetic field generating component 120.

[0052] In some other embodiments, if there is no target object in the fresh-keeping space 1112, the robotic arm 140 returns the magnetic field generating assembly 120 to the initial position, such as the center position on the first side wall 1121, to ensure that the magnetic field in the fresh-keeping space 1112 is in the most uniform state.

[0053] In some embodiments, the refrigerator may also be provided with a display device and a control device, wherein the display device is used to indicate to the user the current position of the magnetic field generating assembly 120 on the first side wall 1121, and the control device is used for the user to operate to control and adjust the position of the magnetic field generating assembly 120 on the first side wall 1121. In this way, the user can be provided with the function of self-adjustment at the same time, thereby improving the user experience.

[0054] In practical applications, the robotic arm 140 adjusts the relative position of the magnetic field generating component 120 on the first sidewall 1121 according to the detection result of the detection device to achieve targeted preservation of the target item. If there is no target item in the space, the magnetic field uniformity in the preservation space 1112 is ensured to be the highest. In this way, the intelligence level of the preservation compartment 100 is improved, and the user does not need to manually adjust the position of the magnetic field generating component 120 on the first sidewall 1121, resulting in a better user experience.

[0055] Regarding how the magnetic field generating component 120 is slidably connected to the first sidewall 1121, the present application provides an embodiment. Please refer to Figure 4 , Figure 4 which is a schematic structural diagram of the magnetic field generating component provided by the embodiment of the present application installed on the first sidewall. Figure 5 which is an exploded view of the magnetic field generating component and the first sidewall provided by the embodiment of the present application. The magnetic field generating component 120 includes a magnetic field generating element 121 and a mounting frame 122, which is used to apply a magnetic field to the preservation space 1112. The magnetic field generating element 121 is installed in the mounting frame 122. One of the mounting frame 122 and the first sidewall 1121 is provided with a sliding groove, and the other is provided with a sliding block. The sliding block cooperates with the sliding groove so that the magnetic field generating component 120 is slidably connected to the first sidewall 1121. Preferably, as Figure 4-Figure 5 , the sliding block 1221 is arranged on the mounting frame 122, and the sliding groove 1116 is arranged on the first sidewall 1121.

[0056] Optionally, the magnetic field generating element 121 includes a plurality of electromagnets. The magnetic field intensities generated by at least two of the plurality of electromagnets are different, and the plurality of electromagnets are arranged at intervals in the mounting frame 122. It should be noted that after the plurality of electromagnets are arranged at intervals on the mounting frame 122, a magnetic field that is more uniform than the magnetic field generated by a single electromagnet can be formed in the preservation space 1112, and the arrangement mode of the plurality of electromagnets is determined according to the shape and magnetic field generating intensity and other characteristics of each electromagnet. In some other embodiments, the magnetic field generating element 121 can also be an electromagnetic coil.

[0057] In some other embodiments, the magnetic field generating element 121 can be set as a magnetic sheet, and in addition to covering the first sidewall 1121, the magnetic sheet can also cover, for example, the circumferential sidewall of the compartment body 110 arranged around the edge of the first sidewall 1121 to improve the magnetic field uniformity in the preservation space 1112. The shape of the magnetic field generating element 121 can be set as an L shape, a C shape, a square shape, etc. according to the sidewall it needs to cover.

[0058] In some embodiments, the magnetic field generating assembly 120 can also be configured as a device with adjustable magnetic field strength. In this way, the magnetic field strength generated by the magnetic field generating assembly 120 can be adjusted according to actual preservation needs, which can not only improve the preservation effect but also save energy consumption.

[0059] For further information, see Figure 6 , Figure 6 The exploded view of the fresh-keeping space provided in the embodiment of the present application. The compartment body 110 includes a drawer assembly 111 and a partition board 112 .

[0060] The drawer assembly 111 forms a fresh-keeping space 1112 with an opening 1113 ; the partition 112 is disposed at the opening 1113 to close the fresh-keeping space 1112 ; the first side wall 1121 is formed on the partition 112 , and the second side wall 1111 is formed on the drawer assembly 111 .

[0061] In some embodiments, the drawer assembly 111 also includes a circumferential side wall 1114 arranged around the edge of the second side wall 1111, and the second side wall 1111 and the circumferential side wall 1114 enclose a fresh-keeping space 1112 with an opening 1113, and the demagnetization reflection plate 130 is also arranged on the surface of the circumferential side wall 1114 located within the fresh-keeping space 1112.

[0062] The magnetic field generating assembly 120 is installed on the surface of the first side wall 1121 facing and / or facing away from the second side wall 1111. Preferably, the magnetic field generating assembly 120 is installed on the surface of the first side wall 1121 facing the second side wall 1111, and the demagnetizing reflector 130 is also arranged on the surface of the first side wall 1121 facing away from the second side wall 1111. It can be understood that by arranging the demagnetizing reflector 130 on the side of the first side wall 1121 away from the fresh-keeping space 1112, a reflection effect can be formed from the back side, so that the magnetic field generated by the magnetic field generating assembly 120 on the side away from the fresh-keeping space 1112 is reflected into the fresh-keeping space 1112, thereby improving the magnetic field utilization rate of the magnetic field generating assembly 120.

[0063] In some embodiments, an air inlet 1115 is provided on the circumferential side wall 1114, and the air inlet 1115 is used to communicate with the cold air duct of the refrigerator to blow cold air into the fresh-keeping space 1112. It can be understood that the demagnetization reflector 130 has good thermal conductivity and can quickly conduct the cold air in the cold air to improve the uniformity of the cold air distribution in the fresh-keeping space 1112, thereby improving the fresh-keeping effect of the fresh-keeping compartment 100.

[0064] The fresh-keeping chamber 100 provided in the embodiment of the present application, on the one hand, by adding a demagnetizing reflective plate 130 to the second side wall 1111, part of the electromagnetic waves emitted by the magnetic field generating assembly 120 will be reflected by the demagnetizing reflective plate 130, thereby forming a reflected magnetic field in the fresh-keeping space 1112, so that the magnetic field intensity of the area near the second side wall 1111 inside the fresh-keeping space 1112 is improved, and the uniformity of the magnetic field in each area of ​​the fresh-keeping space 1112 is increased; on the other hand, based on the high thermal conductivity of the demagnetizing reflective plate 130, the temperature uniformity of each area in the fresh-keeping space 1112 can also be improved; in this way, the magnetic field uniformity and temperature uniformity of each area in the fresh-keeping space 1112 are improved, and the fresh-keeping performance is better.

[0065] The present application also provides a refrigerator, for example, see Figure 7 , Figure 7 The refrigerator 10 includes a refrigerating compartment 200 and the above-mentioned fresh-keeping compartment 100 , and the fresh-keeping compartment 100 is disposed in the refrigerating compartment 200 .

[0066] In some embodiments, see Figure 8 , Figure 8 The exploded view of the refrigeration compartment and the fresh-keeping compartment provided in the embodiment of the present application. The refrigeration compartment 200 includes a refrigeration box 210 and a refrigeration air duct 220 .

[0067] Among them, the fresh-keeping compartment 100 is arranged in the refrigerator box 210; the refrigeration air duct 220 is installed in the refrigerator box 210, and the refrigeration air duct 220 includes a connected air inlet (not shown in the figure) and an air supply outlet 221, the air inlet is used to communicate with the cold air duct of the refrigerator, and the air supply outlet 221 is connected to the fresh-keeping space 1112.

[0068] In actual application, the cold air generated by the cooling air duct enters the refrigeration air duct 220 through the air inlet, and flows into the fresh-keeping space 1112 through the air supply port 221 after being guided by the refrigeration air duct 220 to preserve the items in the fresh-keeping space 1112.

[0069] The refrigeration air duct 220 is installed on the back plate of the refrigerator liner 210. One of the drawer assembly 111 and the refrigerator liner 210 is provided with a slide rail, and the other is provided with a slide groove, so that the drawer assembly 111 is slidably connected with the refrigerator liner 210 to slide out or slide into the refrigerator liner 210. The partition 112 is fixedly installed on the refrigerator liner 210, and during the sliding process of the drawer assembly 111, the partition 112 at least closes a part of the opening 1113.

[0070] In the refrigerator 10 provided in the embodiment of the present application, in its fresh-keeping compartment 100, a demagnetizing reflective plate 130 is additionally provided on the second side wall 1111, so that part of the electromagnetic waves emitted by the magnetic field generating assembly 120 will be reflected by the demagnetizing reflective plate 130, thereby forming a reflected magnetic field in the fresh-keeping space 1112, so that the magnetic field strength of the area inside the fresh-keeping space 1112 close to the second side wall 1111 is increased, and the uniformity of the magnetic field in each area of ​​the fresh-keeping space 1112 is increased, thereby improving the fresh-keeping performance of the fresh-keeping compartment 100.
