[0080] The following will be described in conjunction with Figures 1 to 24 A door assembly and a refrigeration appliance are described. The door assembly in the present application can be applied to a household appliance, such as a refrigerator, but it should be understood that the door assembly in the present application can also be applied to a dishwasher, a washing machine or any other suitable appliance. The refrigeration appliance in the present application is applied, for example, to a refrigerator, but it should be understood that the refrigeration appliance in the present application can also be applied to a freezer or any other suitable appliance.

[0081] In one embodiment of the present application, as Figure 1 and Figure 2 shown, the door assembly is applied to a refrigeration appliance, and the refrigeration appliance includes a cabinet 1 connected in transmission with a door panel 21 through the door assembly. The door assembly includes: a cabinet door 2 rotatably connected to the cabinet 1 and adapted to open or close a storage space of the cabinet 1, the cabinet door 2 being adapted to be slidably connected with the door panel 21. A main sliding door mechanism 7 is provided on the cabinet door 2, and the main sliding door mechanism 7 is connected with the cabinet 1 through a traction mechanism. During opening or closing of the cabinet door 2, the cabinet 1 drives the main sliding door mechanism 7 through the traction mechanism, so that the main sliding door mechanism 7 drives the door panel 21 to slide relative to the width direction of the cabinet door 2.

[0082] It can be understood that the color and material of the door panel 21 of the embodiment can be designed according to the user's needs, and the color and material of the door panel 21 can be matched with (for example, consistent with or matched with the outer surface of the cabinet body to form a decorative pattern) the color and material of the outer surface of the cabinet body, so as to improve the overall aesthetics of the cabinet body.

[0083] The active sliding door mechanism 7 can include sliding blocks and sliding rails and other relative sliding movable components, and the two relatively slidable components are connected with the cabinet door 2 and the door panel 21 through appropriate connection methods (such as bolt connection, welding, etc.), and the active sliding door mechanism 7 is connected with the cabinet body 1 through a traction mechanism. In this way, when the cabinet door 2 is opened and closed by rotating, the cabinet body 1 rotates relative to the cabinet door 2, so that the active sliding door mechanism 7 is driven by the traction mechanism, and the active sliding door mechanism 7 can drive the door panel 21 to move relative to the width direction of the cabinet door 2 (for example, as shown by the double-headed arrow in Figure 1

[0084] It can be understood that the width direction of the cabinet door 2 is parallel to the plane where the cabinet door 2 is located, and is perpendicular to the rotation shaft of the cabinet door 2, so that the door panel 21 can move away from or close to the rotation shaft of the cabinet door 2.

[0085] It should be noted that the parallel and perpendicular relationship in the present application needs to consider the installation error between various components, and a positive or negative 10° error should be understood as the scope protected by the patent.

[0086] Specifically, in the process of opening the cabinet door 2 by rotating to the outside of the cabinet body 1 (for example, as shown by the arc-shaped arrow in Figure 1

[0087] According to the door body assembly of the embodiment of the present application, the cabinet door 2 is rotationally connected to the cabinet body 1, and the active sliding door mechanism 7 is arranged on the cabinet door 2, and the active sliding door mechanism 7 is connected with the cabinet body 1 and the door panel 21, so that in the process of opening or closing the cabinet door 2 by rotating relative to the cabinet body 1, the cabinet body 1 drives the active sliding door mechanism 7 through the traction mechanism, and the active sliding door mechanism 7 drives the door panel 21 to slide relative to the cabinet door 2. In the process of opening the cabinet door 2, the door panel 21 is controlled to move outward, and in the process of closing the cabinet door 2, the door panel 21 is controlled to move inward, so that the door panel 21 can avoid the obstacles such as walls and objects on the side in the process of opening or closing the cabinet door 2, and avoid the interference between the door panel 21 and the obstacles to affect the rotation of the cabinet door 2, so as to meet the use needs of the user in different scenes.​​

[0088] In one embodiment of the present application, as shown in Figures 4 to 6 , the traction mechanism includes a traction rod 709, a first rotating shaft fixing seat 707, and a second rotating shaft fixing seat 710. The first rotating shaft fixing seat 707 is connected to the active sliding door mechanism 7, and the second rotating shaft fixing seat 710 is used to be connected to the box body 1. One end of the traction rod 709 is rotationally connected to the first rotating shaft fixing seat 707, and the other end of the traction rod 709 is rotationally connected to the second rotating shaft fixing seat 710.

[0089] When the box door 2 rotates outward, the first rotating shaft fixing seat 707 drives the active sliding door mechanism 7 to move the door panel 21 outward relative to the box body 1 through the transmission action of the traction rod 709. During the closing process of the box door 2, the box door 2 rotates inward, and the active sliding door mechanism 7 moves the door panel 21 inward relative to the box body 1 through the transmission action of the traction rod 709.

[0090] In one embodiment of the present application, as shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , the active sliding door mechanism 7 includes a first base 717, a first sliding block 714, and a second sliding block 713. The first base 717 has a first guide rail on one side and a second guide rail on the other side. The first sliding block 714 is transmissionally connected to the box body 1 through the traction mechanism and is slidably arranged on the first guide rail. The second sliding block 713 is connected to the door panel 21 and is slidably arranged on the second guide rail. The connecting piece 706 is connected to the first sliding block 714 and the second sliding block 713 at both ends. During the opening or closing process of the box door 2, the box body 1 drives the first sliding block 714 to move on the first guide rail through the traction mechanism, and the first sliding block 714 drives the second sliding block 713 to move in the opposite direction on the second guide rail through the connecting piece 706, so as to drive the door panel 21 to move relative to the box door 2.

[0091] It should be noted that in actual application, the design of the first sliding block 714 and the second sliding block 713 and other sliding blocks in the present application can be flexible and varied to adapt to different working scenarios and performance requirements. They are not limited to specific shapes, sizes or materials, but can be customized and optimized according to specific needs.

[0092] From the perspective of materials, the first sliding block 714 and the second sliding block 713 and other sliding blocks in the present application can choose materials with high wear resistance, low friction coefficient and good stability, such as metal alloy, engineering plastic or special lubricating material. The selection of these materials aims to improve the durability of the sliding block, reduce wear and noise during sliding, and ensure smooth sliding.

[0093] In terms of structural design, the first slider 714, the second slider 713, and other sliders in this application can adopt various forms of guide rail contact surfaces, such as planar contact, ball contact, or sliding bearing contact. Each of these different contact methods has its advantages and disadvantages. For example, ball contact can reduce friction and wear, but it is more expensive; while planar contact has a simple structure, but may require more frequent lubrication and maintenance. Therefore, factors such as usage conditions, cost-effectiveness, and ease of maintenance should be comprehensively considered when making a selection.

[0094] The connector 706 can be a traction rope, transmission belt or other connecting component. The two ends of the connector 706 are connected to the first slider 714 and the second slider 713 respectively, so that the first slider 714 can drive the second slider 713 to move synchronously, thereby driving the door panel 21 to slide relative to the box door 2.

[0095] By reasonably setting the extension direction of the connector 706, the first slider 714 and the second slider 713 move in opposite directions during movement, thereby driving the door panel 21 to avoid obstacles.

[0096] Specifically, during the process of the door 2 rotating outwards to open the box body 1, the box body 1 drives the first slider 714 to slide towards the first hinge 4 via a traction mechanism. Simultaneously, the first slider 714, through the connector 706, drives the second slider 713 to slide in the opposite direction (i.e., away from the first hinge 4), thereby preventing interference between the door panel 21 and external obstacles. During the process of the door 2 rotating outwards to close the box body 1, the box body 1 drives the first slider 714 to slide away from the first hinge 4 via a traction mechanism. Simultaneously, the first slider 714, through the connector 706, drives the second slider 713 to slide in the opposite direction (i.e., towards the first hinge 4), thereby preventing interference between the closed door panel 21 and obstacles.

[0097] like Figures 4 to 6 As shown, the first rotating shaft fixing seat 707 is connected to the first slider 714, the second rotating shaft fixing seat 710 is used to connect to the housing 1, one end of the traction rod 709 is rotatably connected to the first rotating shaft fixing seat 707, and the other end of the traction rod 709 is rotatably connected to the second rotating shaft fixing seat 710.

[0098] In the embodiment, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 are fixed on the first sliding block 714 and the box body 1 respectively, and the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710 are connected through the traction rod 709, so that the distance between the first sliding block 714 and the second rotating shaft fixing seat 710 is always kept unchanged. When the box door 2 rotates relative to the box body 1, the angle between the box body 1 and the box door 2 changes, so that the first sliding block 714 is dragged to slide on the first base 717 through the transmission connection of the traction rod 709, the first rotating shaft fixing seat 707 and the second rotating shaft fixing seat 710, and the second sliding block 713 is driven to slide to realize the movement of the door plate 21 relative to the box door 2.

[0099] Specifically, one end of the traction rod 709 and the first rotating shaft fixing seat 707 are rotatably connected through the pin shaft 708 and the third bearing 715, and the other end and the second rotating shaft fixing seat 710 are rotatably connected through another pin shaft 708 and another third bearing 715.

[0100] In an embodiment of the present application, as shown in Figure 2 、 Figures 4 to 9 The second sliding block 713 is provided with a first connecting block 712, and the first connecting block 712 is formed with a slot for hanging the door plate 21.

[0101] The door body assembly further comprises a first driven sliding door mechanism 8 and a second driven sliding door mechanism 9. The first driven sliding door mechanism 8 is arranged on the box door 2. The first driven sliding door mechanism 8 comprises a second base 817 and a third sliding block 813, the second base 817 is formed with a third guide rail, the third sliding block 813 is slidably arranged on the third guide rail, the third sliding block 813 is provided with a second connecting block 812, and the second connecting block 812 is formed with a slot for hanging the door plate 21.

[0102] The second driven sliding door mechanism 9 is arranged on the box door 2. The second driven sliding door mechanism 9 comprises a third base 902 and a fourth sliding block 903, the third base 902 is formed with a fourth guide rail, the fourth sliding block 903 is slidably arranged on the fourth guide rail, the fourth sliding block 903 is provided with a third connecting block 905, and the third connecting block 905 is formed with a slot for hanging the door plate 21.

[0103] In the present embodiment, by providing the first driven sliding door mechanism 8 and the second driven sliding door mechanism 9 on the cabinet door 2, the first driven sliding door mechanism 8 and the second driven sliding door mechanism 9 respectively have a second base 817 and a third base 902, the second base 817 and the third base 902 are respectively provided with a third sliding block 813 and a fourth sliding block 903 which can slide along the base, and the third sliding block 813 and the fourth sliding block 903 are respectively connected with the door panel 21 through a second connecting block 812 and a third connecting block 905. The third sliding block 813 and the fourth sliding block 903 can slide with the door panel 21 when the door panel 21 slides relative to the cabinet door 2, and assist the sliding of the door panel 21, so that the door panel 21 slides more smoothly relative to the cabinet door 2. At the same time, the first driven sliding door mechanism 8 and the second driven sliding door mechanism 9 can cooperate with the driven sliding door mechanism 7 to limit the movement direction of the door panel 21, reduce the shaking of the door panel 21 during sliding, and make the sliding more stable.

[0104] In addition, the slots on the second connecting block 812, the second connecting block 812 and the third connecting block 905 can facilitate the user to disassemble and replace the door panel 21 on the driven sliding door mechanism 7 and the two driven sliding door mechanisms to meet the different use scenarios of the user.

[0105] Correspondingly, the door panel 21 is provided with a connecting assembly (such as a hook, a plug, etc.) matched with the slot.

[0106] Optionally, one of the first driven sliding door mechanism 8 and the second driven sliding door mechanism 9 can be coaxially arranged with the driven sliding door mechanism 7, and the other is arranged with the driven sliding door mechanism 7.

[0107] In a specific embodiment, as shown in Figure 2 , Figure 6 and Figure 7 , the first driven sliding door mechanism 8 is coaxially arranged with the driven sliding door mechanism 7, and the third sliding block 813 can slide coaxially with the driven sliding door mechanism 7 by coaxially arranging the first driven sliding door mechanism 8 with the driven sliding door mechanism 7, which better assists the door panel 21 to slide relative to the cabinet door 2 under the drive of the driven sliding door mechanism 7. At the same time, the second connecting block 812 can cooperate with the driven sliding door mechanism 7 to limit the movement direction of the door panel 21, so as to avoid the door panel 21 from swinging during movement. The coaxial arrangement of the first driven sliding door mechanism 8 and the driven sliding door mechanism 7 means sharing the same center line or axis, which helps to ensure that the door panel 21 can maintain stable linear motion during sliding, reducing the possibility of deviation or swinging. The coaxial arrangement is used for occasions that require precise control of the movement direction or the relative position relationship between components.

[0108] As shown in Figure 2 , Figure 8 and Figure 9As shown, the second driven sliding door mechanism 9 is arranged in a different axis from the main sliding door mechanism 7. Due to the different axis arrangement, the third connecting block 905 can limit the movement direction of the door panel 21 in cooperation with the main sliding door mechanism 7, avoiding the door panel 21 from deflecting around the sliding direction when sliding, and the sliding process is more stable and reliable. The different axis arrangement of the second driven sliding door mechanism 9 and the main sliding door mechanism 7 means that they do not share the same center line or axis. This configuration is used to provide additional support, stability or prevent the door panel 21 from deflecting around the sliding direction during the sliding process. The different axis arrangement is used in situations where it is necessary to disperse force, increase stability or achieve a complex movement trajectory.

[0109] In an embodiment of the present application, as shown in Figure 10 and Figure 11 The top of the door panel 21 is provided with a first hook 2111, and the bottom of the door panel 21 is provided with a second hook 2112, and the length of the second hook 2112 is greater than the length of the first hook 2111. The first hook 2111 and the second hook 2112 are adapted to be inserted into the corresponding slots.

[0110] In this embodiment, by arranging the first hook 2111 and the second hook 2112 on the top and bottom of the door panel 21 respectively, the door panel 21 can be connected with the slots of the main sliding door mechanism 7 and the driven sliding door mechanism through the first hook 2111 and the second hook 2112, so as to slidably connect the door panel 21 with the cabinet door 2. The first hook 2111 and the second hook 2112 are respectively located on the top and bottom of the door panel 21, so that the door panel 21 is not easy to shake.

[0111] In addition, the length of the second hook 2112 is greater than the length of the first hook 2111. When installing the door panel 21 on the outside of the cabinet door 2, the slot located at the bottom is first hooked with the second hook 2112 of the door panel 21 to preliminarily position the bottom of the door panel 21, and then the position and angle of the door panel 21 are adjusted so that the first hook 2111 on the top of the door panel 21 is inserted into the slot located on the top of the cabinet door 2, making it easier for the user to align the slots with the first hook 2111 and the second hook 2112, and the installation is more convenient.

[0112] Specifically, the first hook 2111 includes a connecting portion and a hook portion arranged on the connecting portion, the hook portion is in the shape of a hook for hooking into the slot, and the connecting portion is provided with at least one waist-shaped hole extending in the horizontal direction and at least one waist-shaped hole extending in the vertical direction.

[0151] In another aspect of the embodiment of the present application, as shown in Figure 1 and Figure 2 , a refrigeration equipment is provided, comprising a cabinet 1 and a door assembly provided in any of the above embodiments. Wherein, the cabinet 1 is formed with a storage space, and the cabinet door 2 is rotatably connected to the cabinet 1 and is adapted to open or close the storage space.

[0152] In the present embodiment, the door assembly comprises the cabinet door 2 and the driven sliding door mechanism 7. The driven sliding door mechanism 7 is arranged on the cabinet door 2 and is configured to drive the door plate 21 to move relative to the width direction of the cabinet door 2 during the opening or closing of the cabinet door 2.

[0153] By setting a door panel 21 on the cabinet door 2, when the refrigeration equipment is embedded and set in a recessed space, or when it is set between two cabinets, the door panel 21 can be set flush with the cabinets on the side wall or sides of the recess, so as to reduce the gap between the refrigeration equipment and the adjacent wall or cabinet, making it more aesthetically pleasing.

[0154] Meanwhile, when the cabinet door 2 rotates, the active sliding door mechanism 7 can drive the door panel 21 to move relative to the cabinet door 2 during the rotation process, so as to move away from the wall or cabinet of the side door of the cabinet 1 as much as possible, so as to avoid these obstacles blocking the door panel 21 and affecting the rotation of the cabinet door 2, causing the cabinet door 2 to be unable to open or close normally.

[0155] The combination of door 2 and door panel 21 ensures that the refrigeration unit can open and close without interference between the door panel 21 and surrounding objects, greatly improving ease of use. This design advantage is particularly evident in confined kitchen environments. Furthermore, the active sliding door mechanism 7 allows the door panel 21 to move smoothly during opening and closing, enhancing the refrigerator's lifespan and stability.

A door panel 21 is provided on the outer side of the cabinet door 2 of the refrigeration device's cabinet body 1. The material and color of the door panel 21 can be designed to be similar to or the same as the material and color of the outer wall of the cabinet. When the door 2 is closed, the door panel 21 is flush with the outer wall of the cabinet at the edge of the slotted structure opening, and fits as close as possible to the opening of the slotted structure, so that the door panel 21 and the outer wall of the cabinet maintain visual consistency and have minimal gaps, making it more aesthetically pleasing.

[0158] When the cabinet door 2 is rotated outward to open, the active sliding door mechanism 7 drives the door panel 21 to slide away from the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side closer to the first hinge 4, which would prevent the cabinet door 2 from opening to a larger angle. When the cabinet door 2 is rotated to close, the active sliding door mechanism 7 drives the door panel 21 to slide closer to the first hinge 4 to avoid interference between the door panel 21 and the cabinet wall on the side away from the first hinge 4, which would prevent the cabinet door 2 from closing completely and affecting the refrigeration and preservation effect in the storage space. Furthermore, when the cabinet door 2 is fully closed, the door panel 21 can return to a state flush with the cabinet body.

[0159] Optionally, the cabinet 1 can have one or more storage spaces, each of which is provided with a door body assembly. It can be understood that the plurality of storage spaces can be arranged in any manner, such as up-down arrangement, left-right arrangement, etc.
