[0014] When the bottle holder is in the assembly position, it is clamped between the first support portion and the second support portion, and the bottle holder is also provided with a second clamping protrusion extending laterally;

[0015] When the bottle holder is clamped between the first supporting portion and the second supporting portion, the first clamping protrusion extends into the first positioning hole, and the second clamping protrusion extends into the second positioning hole.

[0016] Furthermore, the bottom wall surface is also provided with a downwardly extending stopper, which is configured to abut against the rotational positioning portion when the rotational positioning portion rotates until the first engaging protrusion is fully extended into the first positioning hole, so as to limit the rotational positioning portion from rotating in a direction close to the first positioning hole.

[0017] Furthermore, a hook is provided at the lower end of the shift member, and a bayonet is provided at the rotation positioning portion. The hook is configured to engage with the bayonet when the first engaging protrusion is fully extended into the first positioning hole, so as to limit the rotation positioning portion from rotating in a direction away from the first positioning hole.

[0018] Furthermore, the bottle holder includes a lifting plate extending transversely and a surrounding wall extending upward along the outer edge of the lifting plate, and the surrounding wall is configured to limit the transverse movement of the first bottle holder when the first bottle holder is stacked on the lifting plate.

When the user needs to clean the door, the bottle holder can be removed and the door lining of the refrigerator can be wiped. Since the refrigerator door lining structure is flat and has fewer corners after the bottle holder is removed, it is more convenient and quick for the user to clean the door. And since the first bottle holder is stacked on the bottle holder, the first bottle holders for different types of refrigerators can be interchangeable, which enhances the adaptability of the first bottle holder. Since the first bottle holder of the present invention is not provided with an assembly structure that cooperates with the bottle holder, its appearance is relatively complete, and it can be separated from the refrigerator and used as an independent storage box, so that the use scenarios of the first bottle holder are more diverse.

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] like Figures 1 to 12 Shown is a preferred embodiment of the present invention.

[0043] The bottle holder assembly in this embodiment can be set in the refrigerator, and can also be separated from the refrigerator and used as a separate storage device. Specifically, the first bottle holder 111 in the bottle holder assembly is used as a storage device. The bottle holder assembly includes a bottle holder 120 and the first bottle holder 111. The bottle holder 120 is connected to the door lining 11 of the refrigerator, and can be connected to the door lining 11 of the refrigerator in a detachable manner. For example, the bottle holder 120 can be snap-fitted or plugged into the door lining 11 of the refrigerator. The first bottle holder 111 is used for loading articles, and has a first working state and a second working state. The first bottle holder 111 is configured to be stacked on the bottle holder 120 when in the first working state (the term "stacked on" means that no assembly structure is provided between the first bottle holder 111 and the bottle holder 120. After the first bottle holder 111 is placed on the bottle holder 120, the bottle holder 120 mainly provides a vertical upward force to the first bottle holder 111 to balance the gravity of the first bottle holder 111). It is used to store articles in the refrigerator, and is separately arranged outside the refrigerator when in the second working state to be used as an independent storage box.

[0044] Since the bottle holder 120 is detachably connected to the door lining 11 of the refrigerator, the processing of the door lining 11 is simpler than that of the bottle holder 120 being integrally processed from the door lining 11. In addition, since the first bottle holder 111 is stacked on the bottle holder 120, the first bottle holder 111 does not need to be provided with any assembly structure, which facilitates the processing of the first bottle holder 111 and makes it more independent. During the production process of the refrigerator, the first bottle holders 111 of refrigerators of different specifications can be used interchangeably, that is, the first bottle holders 111 of the same style can be provided on multiple refrigerators of different specifications, which enhances the adaptability of the first bottle holder 111. During the use of the refrigerator, the first bottle holder 111 can be separated from the refrigerator and used as an independent storage container, which enriches the functionality of the first bottle holder 111. In particular, when the first bottle holder 111 is independently arranged outside the refrigerator as a storage box, since the bottle holder 120 is detachable, after the refrigerator door 10 is closed, the space originally occupied by the bottle holder 120 and the first bottle holder 111 can be used to store items, thereby increasing the storage space of the refrigerator.

[0045] The bottle holder 120 can be detachably connected to the door lining 11 by any known structure. For example, the bottle holder 120 can be snap-fitted or plug-fitted to the door lining 11 of the refrigerator. Figure 9-10 As shown, in order to achieve a detachable connection between the bottle holder 120 and the door lining 11, the refrigerator further includes a rotation positioning portion 150. The rotation positioning portion 150 is connected to the bottom wall surface of the bottle holder 120 and is configured to rotate around an axis perpendicular to the bottom wall surface. Specifically, in order to achieve the purpose of allowing the rotation positioning portion 150 to rotate around an axis perpendicular to the bottom wall surface of the bottle holder 120, a vertically extending (with the position and orientation of the bottle holder 120 after assembly as a reference) rotation shaft 124 can be provided on the bottom wall surface of the bottle holder 120, and a rotation hole 153 that cooperates with the rotation shaft 124 of the bottle holder 120 is provided on the rotation positioning portion 150, and the rotation positioning portion 150 is configured to rotate around the rotation shaft 124. The rotation positioning portion 150 includes a first clamping protrusion 151 extending laterally. The door lining 11 is formed with a first positioning hole 12 extending transversely, and the rotation positioning part 150 is configured such that when the bottle holder 120 is in the assembly position connected to the door lining 11, the rotation positioning part 150 can rotate to make the first clamping protrusion 151 extend into the first positioning hole 12, so that the bottle holder 120 is connected to the door lining 11. That is, when the bottle holder 120 is in the assembly position, the rotation positioning part 150 rotates until the first clamping protrusion 151 extends into the first positioning hole 12, because both the first clamping protrusion 151 and the first positioning hole 12 extend transversely, the first positioning hole 12 gives the bottle holder 120 a vertical upward supporting force through the first clamping protrusion 151, so as to realize the positioning of the bottle holder 120. In other embodiments, in order to make the positioning of the door lining 11 and the bottle holder 120 more stable, multiple rotation positioning parts 150 and corresponding multiple first positioning holes 12 can be provided.

[0046] The door lining 11 includes a first support portion 11a and a second support portion 11b arranged vertically, and the first support portion 11a and the second support portion 11b are respectively arranged adjacent to two opposite vertical sides of the door 10. The first support portion 11a and the second support portion 11b can both extend in a direction perpendicular to the door 10 and be integrally formed by the door lining 11. The bottle holder 120 is clamped in the gap between the first support portion 11a and the second support portion 11b when in the assembly position. In particular, the first positioning hole 12 can be provided on the first support portion 11a and / or the second support portion 11b.

[0047] When there are two rotational positioning portions 150 and two first positioning holes 12, one rotational positioning portion 150 can be provided at a position of the bottle holder 120 adjacent to the first supporting portion 11a, and another rotational positioning portion 150 can be provided at a position of the bottle holder 120 adjacent to the second supporting portion 11b, and the two first positioning holes 12 are respectively provided on the first supporting portion 11a and the second supporting portion 11b, and the first clamping protrusion 151 adjacent to the first supporting portion 11a cooperates with the first positioning hole 12 on the first supporting portion 11a, and the first clamping protrusion 151 adjacent to the second supporting portion 11b cooperates with the first positioning hole 12 on the second supporting portion 11b.

[0048] In the above embodiment, since two rotation positioning parts 150 are required to position the bottle holder 120, the processing cost is high and the operation is troublesome for the user. Figure 8-9 As shown, a first positioning hole 12 with an opening toward the second supporting part 11b can be provided on the first supporting part 11a of the door lining 11, and a second positioning hole 13 with a transverse extension and an opening toward the first supporting part 11a can be provided on the second supporting part 11b. A second clamping protrusion 123 extending transversely is provided at a position adjacent to the second supporting part 11b of the bottle holder 120, and the second clamping protrusion 123 is fixedly connected to the bottle holder 120 and is used to cooperate with the second positioning hole 13. In this way, when the user needs to install the bottle holder 120, the second clamping protrusion 123 can be inserted transversely into the second positioning hole 13 first, and the bottle holder 120 is in the assembly position. At this time, the user rotates the rotating positioning part 150 to rotate the second clamping protrusion 123 of the rotating positioning part 150 so that the second clamping protrusion 123 of the rotating positioning part 150 extends into the first positioning hole 12, and at this time, the opposite ends of the bottle holder 120 can receive the upward support force given by the door lining 11. When the user needs to remove the bottle holder 120, the user just needs to rotate the rotation positioning part 150 in the opposite direction to make the first clamping protrusion 151 extend out of the first positioning hole 12. In the above process, the user only needs to rotate the rotation positioning part 150 to realize the installation and removal of the bottle holder 120, which is simple, convenient and fast.

[0049] In order to prevent the rotation positioning part 150 from interfering with the door lining 11 of the refrigerator during the assembly process of the bottle holder 120, a stopper 125 extending downward can be provided on the bottom wall of the bottle holder 120. The stopper 125 is configured to abut against the rotation positioning part 150 when the rotation positioning part 150 rotates until the first engaging protrusion 151 fully extends into the first positioning hole 12, so as to limit the rotation positioning part 150 from rotating in the direction close to the first positioning hole 12. Figure 11-12 As shown, after the rotation positioning portion 150 abuts against the shift member 125 , it cannot continue to rotate toward the first positioning hole 12 , and the shift member 125 is disposed at a position that allows the first engaging protrusion 151 to fully extend into the first positioning hole 12 .

[0050] In one embodiment, in order to prevent the first engaging protrusion 151 from sliding out of the first positioning hole 12 laterally due to the pressure of the bottle holder 120, a hook 126 can be provided at the lower end of the shift member 125, and a socket 152 can be provided on the rotation positioning portion 150. The hook 126 is configured to engage with the socket 152 of the rotation positioning portion 150 when the first engaging protrusion 151 is fully extended into the first positioning hole 12, so as to limit the rotation positioning portion 150 from rotating in a direction away from the first positioning hole 12. That is, after the hook 126 is engaged with the socket 152, it is difficult for the rotational positioning portion 150 to rotate in the direction away from the first positioning hole 12. It should be noted that the above “limiting the rotational positioning portion 150 from rotating in the direction away from the first positioning hole 12” does not mean that the rotational positioning portion 150 is completely unable to rotate in the direction away from the first positioning hole 12, but only increases the difficulty of the rotational positioning portion 150 rotating in the direction away from the first positioning hole 12. It is mainly to prevent the first engaging protrusion 151 from automatically disengaging from the first positioning hole 12 without human intervention.

[0051] When the first bottle holder 111 is stacked on the bottle holder 120, the opening and closing of the refrigerator door can easily cause the first bottle holder 111 to be displaced laterally and slide down the bottle holder 120. In order to make the first bottle holder 111 more firmly positioned, in one embodiment, the bottle holder 120 may include a lifting plate 121 extending laterally and a surrounding wall 122 extending upward along the outer edge of the lifting plate 121, and the surrounding wall 122 is configured to limit the lateral movement of the first bottle holder 111, specifically the horizontal movement, when the first bottle holder 111 is stacked on the lifting plate 121. That is, when the first bottle holder 111 is stacked on the lifting plate 121 of the bottle holder 120, when the first bottle holder 111 is displaced laterally, the surrounding wall 122 can prevent the first bottle holder 111 from being separated from the lifting plate 121. The height of the surrounding wall 122 depends on the specifications of the first bottle holder 111, and its specific height can be set between 1 cm and 5 cm, such as 1 cm, 3 cm or 5 cm. The size of the lifting plate 121 can be determined according to the internal space of the refrigerator. In one embodiment, the cross-sectional size of the space enclosed by the lifting plate 121 and the surrounding wall 122 can be exactly equal to the transverse cross-sectional size of the first bottle holder 111, that is, the lower end of the first bottle holder 111 is exactly embedded in the space enclosed by the lifting plate 121 and the surrounding wall 122. When the first bottle holder 111 is positioned, it is completely unable to produce horizontal displacement. In another embodiment, the horizontal dimensions of the lifting plate 121 can be made larger than the horizontal dimensions of the first bottle holder 111, so that the bottle holder 120 can be adapted to the first bottle holder 111 of other refrigerators with larger sizes.

[0052] In one embodiment, the bottle holder assembly further includes a second bottle holder 112, and the second bottle holder 112 can be stacked on the first bottle holder 111. That is, two bottle holders can be placed on one bottle holder 120, which enhances the storage capacity of the bottle holder assembly of the refrigerator. In order to facilitate the processing and manufacturing of the first bottle holder 111 and the second bottle holder 112, in one embodiment, the shape, size and structure of the first bottle holder 111 and the second bottle holder 112 can be exactly the same. In this way, only one bottle holder needs to be molded, which reduces the production cost and facilitates the processing of the first bottle holder 111 and the second bottle holder 112. And when the shape, structure and size of the first bottle holder 111 and the second bottle holder 112 are exactly the same, the only difference between the two is the position of arrangement, that is, the bottle holder arranged at the bottom is the first bottle holder 111, and the bottle holder arranged at the top is the second bottle holder 112.

[0053] When the second bottle holder 112 is stacked on the first bottle holder 111, in order to prevent the second bottle holder 112 from being displaced laterally, the opening 1111 of the first bottle holder 111 can be located above it, and the lower bottom plate of the second bottle holder 112 is engaged with the edge of the upper opening 1111 of the first bottle holder 111 to limit the horizontal movement of the second bottle holder 112.

[0054] When the second bottle holder 112 is exactly the same in shape and size as the first bottle holder 111, after the second bottle holder 112 is stacked on the upper opening 1111 of the first bottle holder 111, on the one hand, it will be inconvenient to take out the items in the first bottle holder 111 (it is necessary to lift the second bottle holder 112 when taking out and placing items in the first bottle holder 111), and on the other hand, the vertical height of the items that can be stored in the first bottle holder 111 will be shortened (the second bottle holder 112 limits the height of the items stored in the first bottle holder 111). Therefore, the practicality of the first bottle holder 111 is reduced. In order to solve the above defects, in one embodiment, as Figure 6 As shown, the upper opening 1111 of the first bottle holder 111 includes a stacking area and a picking area, the horizontal cross-section of the second bottle holder 112 is smaller than the horizontal cross-section of the first bottle holder 111, and the second bottle holder 112 is placed at the stacking area of ​​the first bottle holder 111. In this way, objects with a lower vertical height can be placed in the space below the stacking area of ​​the first bottle holder 111, and objects with a higher vertical height can be placed in the space below the picking area of ​​the first bottle holder 111. In addition, the user can also take the objects in the first bottle holder 111 through the picking area of ​​the opening 1111 of the first bottle holder 111, so that when taking the objects in the first bottle holder 111, the user does not need to lift the second bottle holder 112.

[0055] It should be noted that the division of the stacking area and the taking area of ​​the opening 1111 of the first bottle holder 111 is determined by the actual placement position of the second bottle holder 112. That is, where the second bottle holder 112 is stacked on the opening 1111 of the first bottle holder 111, that place can be called the stacking area, and the other parts of the opening 1111 are called the taking area.

[0056] In one embodiment, Figure 1-2 As shown, the first bottle holder 111 and the second bottle holder 112 can both define a storage chamber in the shape of a rectangular parallelepiped, and when the first bottle holder 111 is in the first working state, one of the vertically arranged side walls of the first bottle holder 111 and the second bottle holder 112 is arranged parallel to the refrigerator door 10, and the first bottle holder 111 and the second bottle holder 112 have the same size in a direction perpendicular to the refrigerator door 10. Moreover, when the first bottle holder 111 is in the first working state, the vertical size of the first bottle holder 111 and the second bottle holder 112 can also be made the same. Furthermore, when the first bottle holder 111 and the second bottle holder 112 both define a rectangular storage chamber, and when the second bottle holder 112 does not completely cover the opening 1111 of the first bottle holder 111, the size of the first bottle holder 111 along a direction parallel to the first direction X can be twice the size of the second bottle holder 112 along a direction parallel to the first direction X, wherein the first direction X is horizontal and parallel to the direction of the refrigerator door 10.

[0057] Sometimes, it is necessary to place vertically high objects in the refrigerator. When the objects are so high that the depth of the first bottle holder 111 cannot meet the placement requirements, Figure 1-2 As shown, in one embodiment, the bottle seat assembly may further include a third bottle seat 113 having a larger vertical dimension than the first bottle seat 111. When the depth of the first bottle seat 111 cannot meet the requirements, the third bottle seat 113 may be used to replace the first bottle seat 111. In the above embodiment, although the problem of the vertical height of the bottle seat is solved, it is necessary to process an additional bottle seat with a larger vertical dimension, which increases the cost and is not convenient for manufacturing. Therefore, in another embodiment, the bottle seat assembly may also include a heightening frame 130, and the heightening frame 130 may include a peripheral wall 131 that is annular around a central axis (the term annular means that the projection of the peripheral wall 131 in a plane perpendicular to the above central axis is closed, and is not limited to a circular ring). The first bottle holder 111 has an opening 1111 arranged upward, and the heightening frame 130 is configured to be stacked on the first bottle holder 111 in the working state, and when the heightening frame 130 is in the working state, the peripheral wall 131 extends upward along the edge of the opening 1111, so that the vertical size of the items that can be loaded in the first bottle holder 111 is increased. The heightening frame 130 can increase the vertical size of the first bottle holder 111, and then the first bottle holder 111 can be placed in the first bottle holder 111. The heightening frame 130 has a lower processing and manufacturing cost than the third bottle holder 113 with a higher vertical height. And when the first bottle holder 111 and the second bottle holder 112 have the same shape and size, the heightening frame 130 can be stacked on the first bottle holder 111 and on the second bottle holder 112, so that the heightening frame 130 has a stronger adaptability.

[0058] In one embodiment, the outer side surface of the peripheral wall 131 of the heightened frame 130 may be provided with a locking flange 1312, and the heightened frame 130 includes a locking flange 1312 located above the locking flange 1312 (with a Figure 3In another embodiment, the above-mentioned locking flange 1312 can be provided on the inner side of the peripheral wall 131 of the height-enhancing frame 130, and the part of the peripheral wall 1311 located above the locking flange 1312 is the upper peripheral wall 1311, and the part of the peripheral wall 131 located below the locking flange 1312 is the upper peripheral wall 1313, and the part of the peripheral wall 131 located above the locking flange 1312 is the lower peripheral wall 1313. When the heightening frame 130 is stacked on the first bottle seat 111, the lower peripheral wall 1313 is sleeved on the outer side of the upper end of the first bottle seat 111, the locking flange 1312 abuts against the edge of the upper opening 1111 of the first bottle seat 111, and the upper peripheral wall 1311 extends upward along the edge of the upper opening 1111 of the first bottle seat 111.

[0059] When there is a positioning flange 1312 on the peripheral wall 131 of the heightened frame 130, the number of the positioning flange 1312 can be one or more. When the number of the positioning flange 1312 is one, it can be a sheet-shaped flange extending perpendicularly to the peripheral wall 131 of the heightened frame 130, or it can be a ring-shaped flange arranged around the circumference of the peripheral wall 131 of the heightened frame 130. When there are multiple positioning flanges 1312, they can be multiple sheet-shaped flanges arranged around the circumference of the peripheral wall 131 and perpendicular to the peripheral wall 131 of the heightened frame 130.

[0060] In one embodiment, the dimensions of the upper perimeter wall 1311 and the lower perimeter wall 1313 of the heightening frame 130 in the direction parallel to the above-mentioned central axis can be the same, so that when using the heightening frame 130, the user can choose any end of the heightening frame 130 to extend into the first bottle holder 111 (that is, the upper perimeter wall 1311 and the lower perimeter wall 1313 of the heightening frame 130 have the same functional role, and the arrangement positions of the two can be interchanged in the working state), which facilitates the use of the heightening frame 130. In another embodiment, in order to increase the height of the heightening frame 130, the dimension of the upper perimeter wall 1311 of the heightening frame 130 in the direction parallel to the above-mentioned central axis can be greater than the dimension of the lower perimeter wall 1313 in the direction parallel to the above-mentioned central axis. In particular, the dimension of the upper perimeter wall 1311 in the direction parallel to the above-mentioned central axis can also be made equal to the dimension of the vertical direction of the first bottle holder 111 in the working state, that is, after the heightening frame 130 is stacked on the first bottle holder 111, its depth is doubled.

[0061] The bottle holder assembly may further include an egg box 140, wherein the egg box 140 includes a plate 141, and a plurality of holes 142 for holding eggs are formed on the plate 141. When the egg box 140 is in working state, it can be placed in the first bottle holder 111 and supported by the bottom wall in the first bottle holder 111. When the user needs to use the egg box 140 and the heightening frame 130 at the same time, in order to prevent the egg box 140 and the heightening frame 130 from interfering with each other in position, in one embodiment, the sum of the vertical dimension of the plate 141 and the vertical dimension of the upper wall 1311 can be made less than or equal to the vertical depth of the cavity in the bottle holder. In this way, Figure 4 As shown, the egg box 140 can be placed in the first bottle holder 111 and the heightening frame 130 can be stacked on it. Of course, the egg box 140 can be placed inside and outside the first bottle holder 111, such as Figure 5 As shown, it can also be placed on the heightening frame 130 to increase the storage space of the first bottle holder 111.

[0062] In particular, the number of the bottle holders 120 in the bottle holder assembly is two or more, and the two or more bottle holders 120 are arranged on the door lining 11 of the refrigerator at intervals. At the same time, the number of the first bottle holders 111 is the same as the number of the bottle holders 120, and each first bottle holder 111 is stacked on each bottle holder 120 in a one-to-one correspondence when in the first working state. Figure 1-2 As shown, the bottle holder assembly has three bottle holders 120, one in the middle and one in the lower part, and each bottle holder 120 is stacked with a first bottle holder 111. The bottle holder assembly may only have one first bottle holder 111, one heightening frame 130 or one third bottle holder 113, or the number of the first bottle holder 111, one heightening frame 130 or one third bottle holder 113 may be equal to the number of the first bottle holders 111.

[0063] A second aspect of the present invention further provides a refrigerator, the refrigerator comprising the bottle holder assembly in any of the above embodiments. Figure 1 As shown, three bottle holders 120 are arranged on the door lining 11 of the refrigerator door 10, a first bottle holder 111 is placed on the upper bottle holder 120 and the middle bottle holder 120, and a third bottle holder 113 is placed on the lower bottle holder 120. In other embodiments, a first bottle holder 111 can be placed on each bottle holder 120, and a heightening frame 130 and a second bottle holder 112 can be arranged. The heightening frame 130 and the second bottle holder 112 can be arranged on one of the first bottle holders 111 as needed. Of course, in order to meet the storage requirements to the greatest extent, three heightening frames 130 and three second bottle holders 112 can also be arranged in other embodiments.
