Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigerator. Background Technology

[0002] Currently, refrigerators have two doors, namely a left door and a right door. In order to improve the sealing between the two doors, a vertical partition is set between them. When the doors are opened, the vertical partition folds and remains folded. When the doors are to be closed, the vertical partition unfolds through guide blocks and overlaps with the left and right doors, thereby maintaining a sealed state.

[0003] However, if due to misoperation or other reasons, the vertical partition is in the unfolded state after the door is opened, and the door on the side without the vertical partition is already closed, the vertical partition will be mounted on the other door because the length of the vertical partition and the door with the vertical partition exceeds the original rotation space, thus preventing the door from closing.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] This application addresses, to at least some extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a refrigerator with a door closing assembly on a vertical shelf. The door closing assembly protrudes from the outer surface of the vertical shelf. When the vertical shelf is in the unfolded state and the door on the side without the vertical shelf is already in the closed state, the door closing assembly is triggered. The door closing assembly can drive the vertical shelf from the unfolded state to the folded state, thereby allowing the door to close normally.

[0007] In a first aspect, embodiments of this application provide a refrigerator, which includes a cabinet defining a compartment, a first door, a second door, a vertical partition, and a door closing assembly. The first door is connected to the cabinet and is a portion of the first door used to open or close the compartment. The second door is opposite to the first door and is connected to the cabinet. The second door is a portion of the second door used to open or close the compartment.

[0008] The vertical partition is rotatably connected to the first door body. The vertical partition is configured to have a first position and a second position. When the vertical partition is in the first position, the vertical partition and the first door body are parallel to each other. When the vertical partition is in the second position, the vertical partition and the first door body have an angle between them.

[0009] The closing assembly is connected to the vertical partition and the first door body respectively. At least a portion of the closing assembly protrudes from the outer surface of the vertical partition. After the closing assembly is triggered, the closing assembly drives the vertical partition to switch from the first position to the second position.

[0010] The above structure introduces a triggerable closing component between the vertical partition and the door. When the second door is closed, the vertical partition is automatically folded, thereby avoiding direct contact between the vertical partition and the second door and achieving smooth closing under the non-standard operating procedure of closing the second door first.

[0011] In some embodiments, the door closing component includes:

[0012] A trigger element, a portion of which protrudes from one side surface of the vertical partition facing the housing when the vertical partition is in the first position, and the trigger element is movable relative to that side surface of the vertical partition;

[0013] The active block is slidably connected to the trigger element;

[0014] The first suction-aiding component abuts against the movable block;

[0015] The second suction aid is connected to the first suction aid with a ratchet, and the second suction aid is installed on the first door body;

[0016] A first reset component, with its two ends connected to a vertical partition and a second suction-aid component, is configured to at least drive the vertical partition to switch from a first position to a second position.

[0017] After the trigger is triggered, the trigger moves toward the movable block and moves the movable block away from the first suction aid component, so that the first suction aid component and the second suction aid component are separated, the first reset component is reset, and the vertical partition switches from the first position to the second position.

[0018] From the moment the trigger is touched by the door, to the power transmitted through the moving parts causing the ratchet teeth of the first and second suction aids to separate, and then to the first reset component driving the vertical partition to fold, the entire assembly forms a complete "trigger-transmission-reset" linkage mechanism. This mechanism can automatically complete the folding action of the vertical partition the instant the second door closes, solving the door closing obstruction caused by the vertical partition unfolding, and ensuring that the door can close smoothly and tightly.

[0019] In some embodiments, the side of the trigger member near the movable block is provided as a first inclined surface, and the movable block is provided with a second inclined surface that cooperates with the first inclined surface. The first inclined surface is configured to be inclined toward the first suction aid component from the direction from the trigger member toward the movable block.

[0020] The directional tilt design of the first inclined surface (tilted towards the first suction-aiding component) provides guidance for the engagement between the trigger and the moving component. During the movement of the trigger, the inclined surface exerts a directional constraint force on the moving component, ensuring that the moving component always moves in a preset direction (away from the first suction-aiding component).

[0021] In some embodiments, at least two sliding members are provided on one side of the vertical partition near the second door body, and the sliding members are spaced apart along the height direction of the vertical partition.

[0022] The sliding component can convert the rigid friction between the vertical partition and the second door into sliding friction or rolling friction, which greatly reduces contact resistance and wear.

[0023] In some embodiments, the door closing component further includes:

[0024] The second reset component is located between the inner wall of the movable block and the vertical partition plate. The second reset component is configured to reset the movable block to its initial position after the movable block has moved.

[0025] The third reset component is located between the trigger and the inner wall of the vertical partition. The third reset component is configured to reset the trigger to its initial position after the trigger is triggered.

[0026] When the second door closes and triggers the closing component, when the door opens, the second and third reset components can push the moving part and the trigger part back to their initial positions through their own elasticity, without requiring manual adjustment by the user.

[0027] In some embodiments, the closing assembly further includes a limiting portion disposed inside the vertical partition, the limiting portion being slidably connected to the trigger member, and the limiting portion extending along the depth direction of the vertical partition.

[0028] By setting a limit part, the movement trajectory of the trigger element after triggering can be limited, avoiding movement deviation and improving the movement stability of the trigger element.

[0029] In some embodiments, the first suction-aiding component includes:

[0030] Press the cap to abut against the movable block;

[0031] The connector is movably connected to the press cap. The side of the connector away from the press cap is connected to the ratchet of the second suction aid component. The connector and the press cap together form a receiving cavity.

[0032] An elastic element is located within the receiving cavity.

[0033] As the connector moves toward the pressing cap, the elastic element is compressed, absorbing the impact force during ratchet engagement and preventing the teeth from cracking or deforming due to excessive instantaneous force. Simultaneously, the elasticity of the element ensures the ratchet remains tightly engaged, preventing tooth slippage even under vibration conditions and improving locking reliability.

[0034] In some embodiments, the side of the pressing cap that abuts against the movable block is provided as a third inclined surface, and the movable block is provided with a fourth inclined surface that cooperates with the third inclined surface. The third inclined surface is inclined toward the movable block from the direction of the pressing cap toward the connector.

[0035] The third inclined surface of the pressing cap (inclined towards the connecting part and towards the movable part) cooperates with the fourth inclined surface of the movable part. The guiding effect of the inclined surface can ensure that the pressing cap moves only in the preset direction (towards the connecting part), avoiding the pressing cap from shifting and causing the ratchet of the connecting part and the second suction aid component to misalign.

[0036] In some embodiments, the first reset component is configured as a torsion spring, which is sleeved around the second suction-aid component, and the two ends of the torsion spring are respectively connected to the vertical partition and the second suction-aid component.

[0037] In some embodiments, the closing assembly further includes a mounting member disposed on the inner sidewall of the vertical partition away from the housing when the vertical partition is in the first position. The mounting member is configured to connect one end of the torsion spring to the vertical partition. By disposing the mounting member on the inner sidewall of the vertical partition to connect one end of the torsion spring to the vertical partition, its function is to distribute the force of the torsion spring.

[0038] The refrigerator in this embodiment of the application has a door closing component on the vertical partition. Part of the door closing component protrudes from the outer surface of the vertical partition. After the door closing component is triggered, the door closing component drives the vertical partition to switch from a first position to a second position. Through mechanical linkage, the position of the vertical partition is switched, thereby pushing the first door to close and realizing the normal closing of the first door.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0069] This application provides a refrigerator. Based on the teachings of the technical solution of this application, those skilled in the art can adapt the technical solution of this application to other refrigeration equipment, and these applications should all be included within the protection scope of this application.

[0070] The refrigerator in this application embodiment can be a French door or a French door refrigerator. This application uses a French door refrigerator as an example for description.

[0071] Reference Figure 1 As shown, the refrigerator proposed in this application embodiment includes a cabinet 1. The cabinet 1 includes a shell defining a receiving cavity, an inner liner disposed in the receiving cavity, and a heat insulation layer disposed between the shell and the inner liner for heat insulation.

[0072] The inner liner is defined to have at least one storage compartment. The inner liner is also defined to have an opening communicating with the storage compartment for placing items into or removing food from the storage compartment.

[0073] In addition, there are no restrictions on the shape and size of the box 1. The box 1 can be set as a cuboid box 1.

[0074] In addition, the cooling modes of refrigerators include, but are not limited to, direct cooling, air cooling, and hybrid cooling (direct cooling and air cooling).

[0075] The refrigerator includes a first door 2 and a second door 3, which are arranged to open opposite each other. The dimensions of the first door 2 and the second door 3 are designed according to the opening size of the refrigerator body 1.

[0076] The structures of the first gate 2 and the second gate 3 are symmetrically arranged. The structure of the first gate 2 will be used as an example for explanation.

[0077] The first door body 2 includes a door shell 22 and a door inner liner 21, with the door shell 22 forming the outer outline of the door body. The door inner liner 21 is located on the side of the door shell 22 facing the storage compartment.

[0078] The first door 2 is connected to the housing 1, and the first door 2 is used to open or close the storage compartment. The second door 3 is connected to the housing 1, and the second door 3 is used to open or close the storage compartment.

[0079] To improve the sealing between the two doors, refer to Figure 2 As shown, a vertical partition 4 is provided between the first door body 2 and the second door body 3. The vertical partition 4 is rotatably connected to one of the door bodies. When the first door body 2 and the second door body 3 are closed, the vertical partition 4 is placed between the first door body 2 and the second door body 3.

[0080] The height of the vertical partition 4 is the same as the height of the door. The vertical partition 4 and the door can be rotated by hinges to ensure that the vertical partition 4 can rotate flexibly.

[0081] It should be noted that the vertical partition 4 can be installed on either the first door body 2 or the second door body 3. This embodiment of the application uses the installation of the vertical partition 4 on the first door body 2 as an example for illustration. If the vertical partition 4 is installed on the second door body 3, it is only necessary to arrange the structure of the vertical partition 4 symmetrically.

[0082] The symmetrical setup specifically includes: adjusting the hinge installation position of the vertical partition 4 from the inner edge of the first door 2 to the inner edge of the second door 3, and adjusting the installation position and triggering direction of the closing assembly 5 accordingly, so as to ensure that the vertical partition 4 can also achieve the folding and unfolding functions on the second door 3 that are opposite to those on the first door 2, as well as a good sealing effect.

[0083] This symmetrical arrangement makes the structure of the vertical partition 4 versatile, reduces mold development costs, and facilitates flexible assembly of the production line according to different door designs.

[0084] Vertical partitions 4 are used to divide the door space and enhance sealing. When closing the door, the vertical partitions 4 fold and unfold to achieve closure. Normally, the user closes the left door (first door 2) first, and then closes the right door (second door 3). The vertical partitions 4 unfold under the action of the guide blocks and overlap with the left and right doors to achieve normal closure.

[0085] A vertical partition 4 is disposed on the first door body 2, and the vertical partition 4 is rotatably connected to the first door body 2. The vertical partition 4 is configured to have a first position and a second position.

[0086] Reference Figure 5 As shown, when the vertical partition 4 is in the first position, the vertical partition 4 and the first door 2 are parallel to each other. At this time, the vertical partition 4 is in the unfolded state.

[0087] Reference Figure 6 As shown, when the vertical partition 4 is in the second position, there is an angle between the vertical partition 4 and the first door 2. At this time, the vertical partition 4 is in a folded state.

[0088] However, in case of user error or special needs, close the second door 3 first, and then close the first door 2.

[0089] During this process, when the second door 3 is closed first, the first door 2 is in the open state and the vertical partition 4 is in the unfolded state. When the second door 3 is closed, its inner edge contacts the end of the vertical partition 4. Since the vertical partition 4 is not folded, it will block the second door 3, preventing it from closing completely. If the user needs to close the door at this point, the second door 3 must be reopened to adjust the state of the vertical partition 4, which is cumbersome and affects the user experience.

[0090] Based on the above, this application proposes a closing assembly 5 for the vertical partition 4, which is triggered when the second door 3 is closed, so as to drive the vertical partition 4 to fold.

[0091] By utilizing the physical contact between the second door body 3 and the closing assembly 5, the state of the vertical partition 4 can be changed. Through manual operation or additional electrical control components such as motors and sensors, a purely mechanical automatic triggering can be achieved, thereby improving the reliability of the solution.

[0092] Reference Figure 3 , Figure 4 As shown, the refrigerator includes a door closing assembly 5, which is connected to the first door 2 and the vertical partition 4. A portion of the door closing assembly 5 protrudes from the outer surface of the vertical partition 4. When the door closing assembly 5 is triggered, it can move the vertical partition 4 from a first position to a second position.

[0093] The closing assembly 5 is installed in the vertical partition 4. Part of the closing assembly 5 protrudes from the outer surface of the vertical partition 4. After the closing assembly 5 is triggered, the closing assembly 5 drives the vertical partition 4 to switch from the first position to the second position.

[0094] After the second door 3 is closed, the closing assembly 5 on the first door 2 is squeezed, which causes the entire vertical partition 4 to rotate. The vertical partition 4 changes from an unfolded state to a folded state, thus allowing the first door 2 to close smoothly.

[0095] The above structure introduces a triggerable closing component 5 between the vertical partition 4 and the door body. When the second door body 3 is closed, the vertical partition 4 is automatically folded, thereby avoiding direct contact between the vertical partition 4 and the second door body 3. This enables smooth closing of the door under the non-standard operating procedure of closing the second door body 3 first and then the first door body 2.

[0096] The core of this concept lies in utilizing a mechanical response mechanism triggered by physical contact, eliminating the need for user operation sequences or additional control modules. Physical contact triggering mechanisms offer advantages such as fast response speed and high reliability. Compared to electronic control solutions, mechanical solutions eliminate the need for additional circuit boards, motors, and other components, reducing potential points of failure.

[0097] The above settings improve the flexibility of user operation. Users do not need to remember a fixed door closing procedure. Whether closing the left door first or the right door first, they can close the door smoothly, reducing dependence on the operation procedure, making it suitable for different operation scenarios, and improving user satisfaction.

[0098] The mechanical mechanism is simplified, and folding and resetting are achieved through a single linkage mechanism, reducing the number of parts and lowering manufacturing costs.

[0099] In one embodiment, reference Figure 7 , Figure 8 As shown, the closing assembly 5 includes a trigger 51, a portion of which protrudes from the side surface of the vertical partition 4 facing the housing 1 when the vertical partition 4 is in the first position. The trigger 51 is movable relative to this side surface of the vertical partition 4.

[0100] This design makes the triggering conditions clearly directional. The subsequent action will only be triggered when the door (second door 3) on the side without the vertical partition 4 is closed and touches the part of the trigger 51 that protrudes from the surface. This effectively avoids the situation where the vertical partition 4 is accidentally folded due to the user accidentally touching the trigger 51 when taking or putting away items in daily use, and ensures the stable function of the vertical partition 4 in dividing the internal space of the refrigerator when it is unfolded.

[0101] When the second door 3 closes and the trigger 51 is activated, the movement of the trigger 51 absorbs part of the impact force when the door closes, preventing a rigid collision between the door and the trigger 51. On one hand, this prevents the trigger 51 from breaking or deforming due to excessive instantaneous impact, extending its service life. On the other hand, it also reduces noise generated by the door closing, improving the quietness of the user experience. Furthermore, this movable design eliminates the need for excessive force from the user; it is triggered solely by the force of the door closing normally, further lowering the operational threshold.

[0102] Reference Figure 8 As shown, the closing assembly 5 includes a movable member 52. The movable member 52 is slidably connected to the trigger member 51. The movable member 52 can move as the trigger member 51 moves.

[0103] The movable part 52 and the trigger part 51 are connected by a sliding connection. Compared with the hinge or other connection forms, the sliding connection has a larger contact area and a more fixed movement trajectory. It can quickly and accurately transmit power to the movable part 52 when the trigger part 51 moves, avoiding power loss caused by excessive connection gap or deviation of movement direction.

[0104] The door closing assembly 5 includes a first suction-aiding component 53, which abuts against the movable component 52.

[0105] The door closing assembly 5 includes a second suction aid 54. The second suction aid 54 is ratcheted to the first suction aid 53. The second suction aid 54 is mounted on the first door body 2.

[0106] By connecting the first suction-aiding component 53 and the second suction-aiding component 54 with ratchet teeth, the unfolded state of the vertical partition 4 can be stably locked, ensuring the reliability of space separation. At the same time, it also improves the reliability of the separation action and ensures the precise timing of the folding of the vertical partition 4.

[0107] Specifically, the ratchet connection has a one-way locking feature. When the first suction aid 53 and the second suction aid 54 are connected by the ratchet, the vertical partition 4 can be locked in the first position (expanded state) to prevent the vertical partition 4 from being accidentally folded during use due to factors such as vibration, collision with objects, or its own weight.

[0108] When the moving part 52 moves away from the first suction-aiding component 53 under the action of the trigger 51, it will apply a directional force to the first suction-aiding component 53 to disengage from the ratchet connection, so that the first suction-aiding component 53 and the second suction-aiding component 54 can be accurately separated under the preset force, and there will be no premature separation or incomplete separation.

[0109] This controllable separation method ensures that the folding action of the vertical partition 4 is initiated only under the specific condition that the second door 3 is closed, and the separation action is precisely timed to the subsequent reset action of the first reset component 55. That is, the first reset component 55 can only drive the vertical partition 4 to fold after the ratchet connection is completely separated, avoiding the problem of the vertical partition 4 getting stuck or unable to fold due to incomplete separation, thus ensuring the smoothness and reliability of the entire door closing assembly 5.

[0110] Reference Figure 8 As shown, the second suction-assisted component 54 is installed on the inner liner 21 of the first door body 2, so that when the first reset component 55 is reset, the relative position between the first door body 2 and the vertical partition 4 is changed by the second suction-assisted component 54.

[0111] The door closing assembly 5 includes a first reset component 55. The two ends of the first reset component 55 are respectively connected to a vertical partition 4 and a second suction-assisted component 54. The first reset component 55 is configured to at least move the vertical partition 4 from a first position to a second position.

[0112] By setting the first reset component 55, when the first suction-aid component 53 and the second suction-aid component 54 are separated, the first reset component 55 does not need an additional power source. It can quickly drive the vertical partition 4 to rotate by relying only on its own reset elastic force (such as spring reset) to switch from the unfolded state (first position) parallel to the first door body 2 to the folded state with an angle (second position).

[0113] The entire process is synchronized with the closing action of the second door 3. Users do not need to manually adjust the position of the vertical partition 4, achieving a seamless connection of "door closing - automatic folding of vertical partition 4 - normal door closure", which greatly improves the convenience of use and is especially suitable for closing the door when holding items with both hands.

[0114] In this embodiment, the switching process of the vertical partition 4 is as follows: after the trigger 51 is triggered, the trigger 51 moves toward the movable part 52 and drives the movable part 52 away from the first suction aid 53. The first suction aid 53 and the second suction aid 54 separate, the first reset part 55 is activated, and the vertical partition 4 switches from the first position to the second position.

[0115] From the moment the trigger 51 is touched by the door, to the power transmitted through the movable part 52 causing the ratchet teeth of the first suction-aiding component 53 and the second suction-aiding component 54 to separate, and then to the first reset component 55 driving the vertical partition 4 to fold, the entire assembly forms a complete "trigger-transmission-reset" linkage mechanism. This mechanism can automatically complete the folding action of the vertical partition 4 at the moment the second door 3 closes, solving the door closing obstruction caused by the unfolding of the vertical partition 4, and ensuring that the door can close smoothly and tightly.

[0116] Compared to traditional refrigerators where the vertical shelf 4 needs to be manually adjusted to close the door, this component automates the closing process, avoiding the problem of the door failing to close and cold air leaking due to the user forgetting to adjust the vertical shelf 4, thus significantly improving the reliability of the refrigerator.

[0117] The first reset component 55 is configured as an elastic reset component. In some embodiments, the first reset component 55 is configured as a torsion spring, which is sleeved around the second suction aid component 54. The two ends of the torsion spring are respectively connected to the vertical partition 4 and the second suction aid component 54.

[0118] Automatic position switching is achieved through the elastic properties of the mechanical structure, reducing the user's operational burden.

[0119] It is understood that the elastic force of the first reset component 55 (such as a spring) can be customized according to the weight, size, and rotational resistance of the vertical partition 4 to ensure that it has sufficient power to drive the vertical partition 4 to fold, while avoiding excessive reset force that could cause the vertical partition 4 to fold too quickly and collide with the door or cabinet 1. For example, for larger and heavier vertical partitions 4, a reset component with greater elasticity can be selected; for smaller and lighter vertical partitions 4, a reset component with less elasticity can be used, so that vertical partitions 4 of different specifications can achieve a smooth and stable folding action under the action of the reset component, thereby improving the versatility and adaptability of the closing assembly 5.

[0120] Reference Figure 9 , Figure 11As shown, the vertical partition 4 includes a first housing 41 and a second housing 42, which are fastened together to form the external outline of the vertical partition 4. When the vertical partition 4 is in the first position, the first housing 41 is positioned close to the housing 1, and the second housing 42 is positioned away from the housing 1.

[0121] Reference Figure 11 As shown, a first clearance portion 411 is provided on the first housing 41, and the first clearance portion 411 is configured to accommodate the trigger member 51 passing through the surface of the first housing 41.

[0122] The first housing 41 is provided with a second clearance part 412, which is configured to accommodate the passage of the sliding member 510, so as to reduce the friction when the vertical partition 4 contacts the second door 3.

[0123] In some embodiments, refer to Figure 10 As shown, the closing assembly 5 also includes a mounting member 58, which is located on the inner side wall away from the housing 1 when the vertical partition 4 is in the first position. The mounting member 58 is configured to connect one end of the torsion spring to the vertical partition 4.

[0124] Reference Figure 10 As shown, the mounting member 58 is positioned on the inner wall of the second housing 42 near the first housing 41. One end of the mounting member 58 extends from the surface of the first housing 41 in a direction away from the movable member 52 to form a mounting space. One end of the torsion spring is configured as a bent portion, which cooperates with the mounting member 58 to achieve the connection between the torsion spring and the vertical partition 4.

[0125] Mounting component 58 is located on the inner wall of the vertical partition 4 and is used to connect one end of the torsion spring to the vertical partition 4. Its function is to distribute the force of the torsion spring. If the torsion spring is directly connected to the vertical partition 4, the torque when the torsion spring returns to its original position will be concentrated at the connection point, which can easily lead to excessive local stress and cracking on the inner wall of the vertical partition 4. Mounting component 58 can distribute the torque to a larger area of ​​the vertical partition 4 through its own structure, thereby reducing the local stress intensity.

[0126] Meanwhile, the mounting component 58 can also adjust the initial installation angle of the torsion spring, making it easier to set the initial torque of the torsion spring according to the folding requirements of the vertical partition 4, thereby improving the adaptability of the reset component.

[0127] In some embodiments, refer to Figure 12 , Figure 13As shown, the side of the trigger 51 closest to the movable member 52 is provided with a first inclined surface 511, and the movable member 52 is provided with a second inclined surface 521 that cooperates with the first inclined surface 511. The first inclined surface 511 is constructed to be inclined towards the first suction-assisting component 53 from the direction from the trigger 51 to the movable member 52. Through the cooperation of the first inclined surface 511 and the second inclined surface 521, the moving force of the trigger 51 along the depth direction of the vertical partition 4 (the door closing direction) can be converted into the moving force of the movable member along the width direction of the vertical partition 4 (towards or away from the first suction-assisting component 53). After the power direction is converted by the inclined surface, the movable member 52 can move along the width direction, which has more space and does not require additional expansion of the depth dimension of the vertical partition 4. This effectively compresses the installation volume of the closing assembly 5 inside the vertical partition 4, reserving more space for other functional components of the vertical partition 4 (such as storage compartments and sealing structures).

[0128] Compared to direct pushing with a vertical surface, the inclined surface can reduce the frictional resistance between the trigger 51 and the moving part 52 by increasing the contact area and dispersing the force. When the trigger 51 moves due to being touched by the door, the sliding contact between the first inclined surface 511 and the second inclined surface 521 can reduce jamming and make the power transmission smoother.

[0129] The directional tilt design of the first inclined surface 511 (tilted towards the first suction-assisting component 53) provides guidance for the engagement between the trigger 51 and the movable component 52. During the movement of the trigger 51, the inclined surface exerts a directional constraint force on the movable component 52, ensuring that the movable component 52 always moves along a preset direction (away from the first suction-assisting component 53). This avoids the movable component 52 deviating from the preset trajectory due to factors such as vibration and installation errors, thereby preventing the problem of incomplete separation between the first suction-assisting component 53 and the second suction-assisting component 54. This self-guiding function improves the fault tolerance of the closing assembly 5, ensuring the accuracy of power transmission even in the event of slight deformation of the vertical partition 4 or small assembly gaps in the components.

[0130] In one embodiment, reference Figure 8 , Figure 10 The closing assembly 5 also includes a limiting part 59, which is located inside the vertical partition 4. The limiting part 59 is slidably connected to the trigger 51 and extends along the depth direction of the vertical partition 4.

[0131] After the trigger member 51 is triggered and pressed, the trigger member 51 slides inside the limiting part 59. A second reset member 56 is provided at the bottom of the trigger member 51 to reset the trigger member 51.

[0132] By setting the limit part 59, the movement trajectory of the trigger 51 after triggering can be limited, avoiding movement deviation and improving the movement stability of the trigger.

[0133] In one embodiment, reference Figure 10 , Figure 12 , Figure 13 As shown, the closing assembly 5 also includes a second reset component 56, which is disposed between the movable member 52 and the inner wall of the vertical partition 4. The second reset component 56 is configured to reset the movable member 52 to its initial position after the movable member 52 moves.

[0134] In this embodiment, the second reset component 56 is configured as a telescopic spring. By configuring the telescopic spring, the trigger 51 can be reset by its own elastic force after being triggered.

[0135] In one embodiment, reference Figure 7 , Figure 8 As shown, the closing assembly 5 also includes a third reset component 57, which is disposed between the trigger and the inner wall of the vertical partition 4. The third reset component 57 is configured to reset the trigger 51 to its initial position after the trigger 51 is triggered.

[0136] In this embodiment, the third reset component 57 is set as a telescopic spring. By setting the telescopic spring, the movable component 52 can be reset by its own elastic force after being triggered.

[0137] When the second door 3 closes and triggers the closing component 5 to operate, when the door opens, the second reset component 56 and the third reset component 57 can push the movable component 52 and the trigger component 51 back to their initial positions through their own elasticity, without requiring manual adjustment by the user.

[0138] Specifically: the second reset component 56 is compressed when the movable part 52 moves away from the first suction-aiding component 53. After the door opens, its elasticity pushes the movable part 52 back into contact with the first suction-aiding component 53, preparing for the next ratchet engagement lock. The third reset component 57 is compressed when the trigger 51 moves inward toward the vertical partition 4. After the door opens, its elasticity pushes the trigger 51 back out of the surface of the vertical partition 4, restoring its triggering capability. This automatic reset function ensures that the closing assembly 5 is reusable and requires no user intervention, further improving the product's automation and ease of use.

[0139] Reference Figure 8 As shown, the closing assembly 5 includes an abutment portion 512, which is connected to the side of the third reset component 57 away from the movable member 52. The abutment portion 512 extends along the height direction of the vertical partition 4. The abutment portion 512 is used to apply an abutment force to the third reset component 57 so that the third reset component 57 can drive the movable member 52 to reset.

[0140] In one embodiment, reference Figure 3As shown, at least two sliding members 510 are provided on one side of the vertical partition 4 near the second door 3, and the sliding members 510 are spaced apart along the height direction of the vertical partition 4.

[0141] When the vertical shelf 4 is in the unfolded state (first position) and the second door 3 is closed, the side of the vertical shelf 4 will contact the edge of the second door 3. If rigid contact is used directly, long-term collision and friction can easily lead to wear on the paint surface of the side of the vertical shelf 4 or the edge of the second door 3, and deformation of plastic parts, affecting the appearance and sealing of the refrigerator. The sliding component 510 can convert the rigid friction between the vertical shelf 4 and the second door 3 into sliding friction or rolling friction, significantly reducing contact resistance and wear. For example, when using a roller-type sliding component 510, the second door 3 contacts the roller when closed. The rolling of the roller can completely avoid scratches caused by sliding friction, while reducing closing noise and improving the user experience.

[0142] Furthermore, by arranging the sliding members 510 at intervals along the height direction of the vertical partition 4 (for example, one at the top and one at the bottom), the vertical partition 4 can play a multi-point guiding role in the rotation trajectory of the vertical partition 4 when it is folded from the first position to the second position, thereby reducing tilting and jamming caused by uneven force on the vertical partition 4 in the height direction.

[0143] In some implementations, refer to Figure 14 , Figure 15 As shown, the first suction aid component 53 includes a pressing cap 531, which abuts against the movable component 52.

[0144] The first suction aid component 53 includes a connector 532, which is movably connected to the pressing cap 531, and the connector 532 and the pressing cap 531 can move relative to each other. The side of the connector 532 away from the pressing cap 531 is connected to the second suction aid component 54 by a ratchet. The connector 532 and the pressing cap 531 have receiving cavities formed inside them.

[0145] The first suction-aiding component 53 includes an elastic element 533, which is disposed in the receiving cavity. When the first suction-aiding component 53 and the second suction-aiding component 54 are connected by ratchet teeth, the connecting member 532 will be subjected to the reaction force of the second suction-aiding component 54. If there is direct rigid contact, it is easy to cause collision damage to the tips of the ratchet teeth. The elastic element 533 (such as a compression spring) in the receiving cavity can buffer this impact force through its own elasticity, so that the ratchet connection process has flexible contact characteristics.

[0146] That is, when the connector 532 moves toward the pressing cap 531, the elastic element 533 is compressed, absorbing the impact force during ratchet engagement and preventing the teeth from cracking or deforming due to excessive instantaneous force. At the same time, the elasticity of the elastic element 533 can also ensure that the ratchet is always tightly engaged, preventing the ratchet from dislodging due to gaps even in a vibrating environment, thus improving locking reliability.

[0147] In some embodiments, refer to Figure 12 As shown, the side of the pressing cap 531 that abuts against the movable member 52 is provided as a third inclined surface 5311, and the movable member 52 is provided with a fourth inclined surface 522 that cooperates with the third inclined surface 5311. The third inclined surface 5311 is inclined towards the movable member 52 from the pressing cap 531 toward the connecting member 532.

[0148] The third inclined surface 5311 of the pressing cap 531 (inclined towards the movable part 52 in the direction of the connecting part 532) cooperates with the fourth inclined surface 522 of the movable part 52, which belongs to the secondary inclined surface transmission, improving the power transmission effect.

[0149] The trigger 51 is pressed, which drives the movable part 52 to move along the width direction of the vertical partition 4. The movable part 52 and the pressing cap 531 are engaged on an inclined surface. The movement of the movable part 52 drives the vertical movement of the pressing cap 531. The pressing cap 531 and the connecting part 532 cooperate with each other.

[0150] First, the first door 2 is closed, then the second door 3 is closed. The trigger 51 does not need to move. The ends of the movable part 52 and the pressing cap 531 abut against each other, ensuring that the position of the pressing cap 531 remains unchanged. The internal elastic part 533 ensures that the first suction aid 53 and the movable part 52 elastically abut against each other. The first suction aid 53 and the second suction aid 54 are connected by ratchet teeth.

[0151] When the second door 3 is closed first and then the first door 2 is closed, the trigger 51 is activated by the pressure of the second door 3, which drives the movable part 52 to move, causing the pressing cap 531 and the connecting part 532 to fall off appropriately. The suction function of the first suction aid 53 and the second suction aid 54 is weakened. During the interval between the reset of the second reset part 56 and the third reset part 57, the first reset part 55 drives the vertical partition 4 to complete the reset, that is, switch from the first position to the second position.

[0152] On the one hand, this fit can further reduce the frictional resistance between the moving part 52 and the pressing cap 531, making the movement of the moving part 52 pushing the pressing cap 531 smoother.

[0153] On the other hand, the guiding effect of the inclined surface ensures that the pressing cap 531 moves only in a preset direction (towards the connector 532), preventing the pressing cap 531 from shifting and causing misalignment of the ratchet between the connector 532 and the second suction aid 54. For example, if there is a slight deviation in the pushing direction of the moving part 52, the cooperation between the third inclined surface 5311 and the fourth inclined surface 522 can convert the deviation force into a positive moving force of the pressing cap 531 through "self-correction," ensuring that the ratchet separation action is precise and controllable.
