[0044] The drawer assembly and the refrigerator provided by the embodiments of the present application can solve the problem that the magnetic field preservation technology of the existing refrigerator cannot intuitively show the user, and the following will be described with reference to the drawings.

[0045] The drawer assembly provided by the embodiments of the present application is applied to a refrigerator, and the refrigerator includes a cabinet, a door body, and a magnetic field generating device. The magnetic field generating device is arranged in the cabinet, and the drawer assembly includes a drawer body 1 and a display piece 2. Please refer to Figure 1 and Figure 2 , Figure 1 The first structural schematic diagram of the drawer assembly provided by the embodiments of the present application is shown in FIG. 1, and the second structural schematic diagram of the drawer assembly provided by the embodiments of the present application is shown in FIG. 2. Figure 2 The first structural schematic diagram of the drawer assembly provided by the embodiments of the present application is shown in FIG. 1, and the second structural schematic diagram of the drawer assembly provided by the embodiments of the present application is shown in FIG. 2. The drawer body 1 is arranged in the cabinet in a pullable manner and is adjacent to the magnetic field generating device. The drawer body 1 is provided with a containing space 11. The display piece 2 is arranged in the containing space 11. The display piece 2 includes a plurality of display units 22. Each display unit 22 has magnetism and can rotate under the action of a preset magnetic force. When the drawer body 1 is pulled relative to the cabinet, the plurality of display units 22 have a first state of rotating to a first pattern when being close to the magnetic field generating device, and a second state of rotating to a second pattern when being away from the magnetic field generating device. The preset magnetic force is not limited further herein.

[0046] The drawer assembly provided by the embodiment of the present application is characterized in that the drawer body 1 is adjacent to the magnetic field generating device, when the drawer body 1 is pulled out relative to the cabinet, the display units 22 in the drawer body 1 move together with the drawer body 1, so that the display units 22 have a state of being close to the magnetic field generating device and a state of being far away from the magnetic field generating device in the process of movement. Since the display units 22 have magnetism and can rotate under the action of a preset magnetic force, when the display units 22 are close to the magnetic field generating device by a preset distance and are subjected to the action of the preset magnetic force, the plurality of display units 22 all rotate and present a first pattern. When the display units 22 are far away from the magnetic field generating device and the distance between the display units 22 and the magnetic field generating device is greater than the preset distance, please refer to Figure 4 , Figure 4 The first structural diagram of the display piece of the drawer assembly provided by the embodiment of the present application is shown in FIG. 2, at this time, the plurality of display units 22 on the display piece 2 are only subjected to the action of gravity and fall freely and present a disordered second pattern. Through the change of the pattern presented by the plurality of display units 22 on the display piece 2 in the process of pulling out the drawer body 1, the invisible magnetic field is visualized, and the user can intuitively understand the magnetic field preservation technology.

[0047] Specifically, when the drawer body 1 is pulled out of the cabinet, the pattern on the display piece 2 changes from the second pattern to the first pattern and then to the second pattern. When the drawer body 1 is pushed into the cabinet, the pattern on the display piece 2 changes from the second pattern to the first pattern and then to the second pattern.

[0048] The first pattern is not further limited here, in some examples, the magnetic field within a preset distance range around the magnetic field generating device is uniform, when the display piece 2 is within the preset distance range around the magnetic field generating device, the plurality of display units 22 are subjected to magnetic forces of the same size and direction, so that the target directions of rotation are the same. At this time, please refer to Figure 5 , Figure 5 The second structural diagram of the display piece of the drawer assembly provided by the embodiment of the present application is shown in FIG. 3, the plurality of display units 22 present the first pattern with the same turning direction. In other examples, the magnetic field within a preset distance range around the magnetic field generating device is not uniform, when the display piece 2 is within the preset distance range around the magnetic field generating device, each display unit 22 is subjected to a corresponding magnetic force and rotates to a corresponding target direction, at this time, the plurality of display units 22 present the first pattern with different turning directions. It can be understood that, whether the magnetic field within the preset distance range around the magnetic field generating device is uniform or not, the first pattern presented by the plurality of display units 22 on the display piece 2 is roughly corresponding to the magnetic field distribution at the position.

[0049] Optionally, the display piece 2 further comprises a substrate 21, and the plurality of display units 22 are movably arranged on the substrate 21; the substrate 21 is arranged in the accommodation space 11 and divides the accommodation space 11 into two parts. That is, the display piece 2 not only can realize the effect of visualizing the magnetic field, but also can divide the accommodation space 11 in the drawer body 1 into different parts, so that the user can manage and access different kinds of storage objects easily.

[0050] Optionally, a plurality of mounting cavities 213 are arranged on the substrate 21 at intervals, and one display unit 22 is movably arranged in each mounting cavity 213; the substrate 21 comprises a cavity wall surrounding each mounting cavity 213, and the cavity wall is made of a transparent material.

[0051] That is, the display unit 22 is movably arranged in the mounting cavity 213 of the substrate 21, and when the display unit 22 switches between the first state and the second state, the display unit 22 moves in the vertical direction in a larger range, so that the change of the display unit 22 when switching between different states is more obvious, and the user can intuitively observe the effect of the magnetic field.

[0052] Specifically, the substrate 21 can comprise a first plate body and a second plate body. A plurality of mounting grooves are arranged on one side of the first plate body at intervals, and one display unit 22 is movably arranged in each mounting groove; the second plate body is sealingly connected with the first plate body and surrounds each mounting groove to form a mounting cavity 213. Therefore, when mounting, each display unit 22 is placed in a mounting groove, and after the plurality of display units 22 are placed, the first plate body and the second plate body are connected to form a sealed substrate 21, so that the mounting operation is simple and easy to operate.

[0053] As an alternative embodiment, the substrate 21 can further comprise a lattice plate and a pair of sealing plates. A plurality of through holes are arranged on the lattice plate at intervals, and the pair of sealing plates are sealingly connected to two sides of the lattice plate respectively and surround each through hole to form a sealed mounting cavity 213. One display unit 22 is arranged in each mounting cavity 213, and each mounting cavity 213 is directly isolated from each other to avoid the display units 22 from moving in the plurality of mounting cavities 213 and affecting observation. When mounting, one sealing plate can be sealingly connected to one side of the lattice plate, so that each through hole and the sealing plate surround a mounting groove, and one display unit 22 is placed in each mounting groove. After the plurality of display units 22 are placed, the other sealing plate is sealingly connected to complete the mounting of the substrate 21.

[0054] Here, the materials of the first plate body and the second plate body, or the lattice plate and the pair of sealing plates are not limited further, which can be polymethyl methacrylate (PMMA), polycarbonate (PC), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polystyrene (PS), polyethylene (PE), polypropylene (PP), polyvinylidene fluoride (PVDF) or polytetrafluoroethylene (PTFE), etc.

[0055] Optionally, the display unit 22 is in the shape of a strip and is made of ferrocarbon alloy. By setting the display unit 22 in the shape of a strip, the rotation of the display unit 22 is more obvious, and it is convenient for the user to observe the rotation of the display unit 22. The ratio of iron and carbon in the ferrocarbon alloy is not limited here, and the display unit 22 can have magnetism and rotate only under a preset magnetic force.

[0056] It should be noted that the storage space 11 of the drawer body 1 can be distributed with a magnetic field to preserve the stored objects in the drawer body 1, and not only in the preset distance range of the magnetic field generating device. The pattern state of the display unit 22 changes during the movement of the drawer body 1, which is due to the limitation of the ratio of iron and carbon in the display unit 22, which increases the magnetic force required for magnetization of the display unit 22, so as to make the effect of the magnetic field explicit through the change of the state of the display unit 22.

[0057] Optionally, the drawer body 1 includes opposite two side walls, and each side wall is provided with a slide 12; the two sides of the base plate 21 are each provided with a slide rod 211, and the base plate 21 is slidably connected to the pair of slides 12 through the pair of slide rods 211, so as to change the proportion of the two parts of the storage space 11.

[0058] That is, the base plate 21 can slide in the drawer body 1, thereby changing the volume ratio of the two parts of the space separated by the base plate 21. The user can slide the base plate 21 according to the storage needs, so that the volume of each part of the space matches the size of the object to be stored, which not only realizes the partition management of food materials, but also avoids the problem that the size of each space is fixed, resulting in a small range of storable objects.

[0059] Here, the specific setting position of the slide 12 is not limited, and it can be set on the opposite two side walls of the drawer body 1, for example, it can be set on the two side walls of the drawer body 1 opposite to the door body, or it can be set on the two side walls of the drawer body 1 adjacent to the door body. Further, each slide 12 extends in the horizontal direction.

[0060] Optionally, the slide 12 is a perforation, and the pair of slide rods 211 are respectively arranged in the pair of perforations, and each slide rod 211 is provided with a limiting block 212 at the end extending outside the drawer body 1, and the outer diameter of the limiting block 212 is greater than the hole diameter of the perforation. By setting the limiting block 212 on the side where the slide rod 211 extends outside the storage space 11, the sliding of the base plate 21 along the extension direction of the slide rod 211 is limited, so as to prevent the base plate 21 from disengaging from the slide 12 when sliding.

[0061] Optionally, the base plate 21 is also rotatably connected to the pair of slides 12 through the pair of slide rods 211. The slide rod 211 can also rotate in the perforation, so that the base plate 21 can rotate in the storage space 11 with the slide rod 211 as the rotation shaft. Please refer toFigure 1 , Figure 1 The first structural diagram of the drawer assembly provided by the embodiment of the present application, when the base plate 21 rotates to the vertical direction, divides the accommodating space 11 into two storage spaces on the left and right sides, please refer to Figure 2 , Figure 2 The second structural diagram of the drawer assembly provided by the embodiment of the present application, when the base plate 21 rotates to the horizontal direction, divides the accommodating space 11 into two storage spaces on the upper and lower sides, at the same time, the base plate 21 can also slide along the slide 12 to change the proportion between the two storage spaces.

[0062] In some examples, the length or width of the base plate 21 is smaller than the length or width of the drawer body 1, so that the base plate 21 can rotate in the accommodating space 11, and the size of the base plate 21 and the size of the drawer body 1 are not limited here.

[0063] As an alternative embodiment, the slide 12 can also be a slide groove opened on the side of the drawer body 1 facing the accommodating space 11, and the base plate 21 is slidably connected with the slide groove through the slide rod 211, further, the side of the slide rod 211 away from the base plate 21 is also provided with a roller, the roller is embedded in the slide groove, and the outer diameter of the roller is greater than the slot of the slide groove, so as to avoid the roller from being separated from the slide groove when rolling in the slide groove, at this time, the base plate 21 can roll in the slide groove through the roller to realize rotation or sliding.

[0064] Optionally, please refer to Figure 3 , Figure 3 The structural diagram of the drawer body of the drawer assembly provided by the embodiment of the present application, the drawer body 1 is provided with a limiting rib 13, the limiting rib 13 is located in the accommodating space 11 and extends along the horizontal direction; the base plate 21 is overlapped with the limiting rib 13 when rotating to the horizontal direction. By setting the limiting rib 13 extending along the horizontal direction, support is provided for the base plate 21 in the horizontal state, so as to facilitate the fixation of the base plate 21 in the horizontal state, and prevent the base plate 21 from shaking. The specific position of the limiting rib 13 is not limited further here, as long as it does not interfere with the rotation of the base plate 21, in some examples, it can be arranged on the same side as one slide 12, and in other examples, it can be arranged adjacent to a pair of slides 12.

[0065] The refrigerator provided by the embodiment of the present application comprises a cabinet, a door body, a magnetic field generating device and the drawer assembly as described above. The door body is rotationally connected with the cabinet. The magnetic field generating device is arranged on one side of the cabinet close to the door body. The drawer assembly comprises a drawer body 1 and a display piece 2. The drawer body 1 is arranged in the cabinet in a pullable manner and is adjacent to the magnetic field generating device. The drawer body 1 is provided with a containing space 11. The display piece 2 is arranged in the containing space 11. The display piece 2 comprises a plurality of display units 22. Each display unit 22 is magnetic and can rotate under the action of a preset magnetic force. When the drawer body 1 is pulled relative to the cabinet, the plurality of display units 22 have a first state of rotating to a first pattern when close to the magnetic field generating device and a second state of rotating to a second pattern when away from the magnetic field generating device.

[0066] Optionally, the magnetic field generating device comprises a permanent magnet or an electromagnet.

[0067] Optionally, the magnetic field generating device is arranged above, below or on a side of the drawer body 1 and on the side of the cabinet close to the door body. Thus, when the display piece 2 passes through the magnetic field generating device, the pattern change on the side close to the door body can be observed by the user. Preferably, the magnetic field generating device is arranged below the drawer body 1. In this case, the fresh-keeping effect of the magnetic field generating device on the food materials in the drawer body 1 is optimal.

The magnetic field generating device is arranged at a lower middle position of the drawer body 1. A limiting rib 13 is arranged on a side wall of the drawer body 1 opposite to the door panel of the drawer body 1. When the base plate 21 is in a vertical state, the height of the base plate 21 is the same as the height of the containing space 11, so as to divide the containing space 11 into two left and right independent storage spaces. When the base plate 21 is in a horizontal state, the base plate 21 is overlapped with the limiting rib 13. The length of the base plate 21 is less than the length of the containing space 11, so as to divide the containing space 11 into two upper and lower storage spaces. The upper and lower storage spaces have a communication port, so as to facilitate placing the food materials in the lower storage space through the communication port.
