[0043] In an embedded furniture, a refrigeration device can be embedded in a cabinet. Among them, the door of the refrigeration device is rotatably connected to the cabinet body of the refrigeration device. The door of the refrigeration device can be used to cover the accommodation space inside the cabinet body, and a decorative panel can be used to cover the cabinet body of the cabinet, so as to combine the outer surface of the cabinet with the home decoration style.

[0044] However, as the door of the refrigeration device is opened, the decorative panel is prone to interference and collision with the side wall of the cabinet, resulting in a poor use experience of the embedded refrigerator. Therefore, the present application proposes a door assembly to solve the defect that the refrigeration device is prone to interference with the side wall of the cabinet during the door opening process, affecting the use experience.

[0045] It should be noted that the door assembly proposed in the present application can be used for the door of a refrigerator, the door of a freezer, or other rotatably connected doors. The following takes a refrigerator as the usage scenario to describe the door assembly of the present application.

[0046] The following will be combined with Figures 1 to 4 to describe the door assembly (hereinafter referred to as the door assembly) of the refrigeration device of the present application and the refrigeration device.

[0047] The door assembly according to the embodiment of the present application includes a door body 100, a sliding door mechanism 200, a decorative panel 400, and a magnetic assembly 300. One end of the door body 100 is adapted to be rotatably connected to a box body 500; the sliding door mechanism 200 is installed on the door body 100, and the sliding door mechanism 200 includes a second slider 220, and the second slider 220 is slidably connected to the door body 100; the decorative panel 400 is slidably connected to the door body 100; the magnetic assembly 300 includes a first magnetic member 310 and a second magnetic member 320, the first magnetic member 310 is installed on the second slider 220, the second magnetic member 320 is installed on the decorative panel 400, and the magnetic pole directions of the first magnetic member 310 and the second magnetic member 320 are opposite; during the door opening process, the door body 100 is adapted to drive the second slider 220 to slide and move the first magnetic member 310 towards the second magnetic member 320, so as to drive the decorative panel 400 to move away from the rotating side of the door body 100.

[0048] For the door assembly according to the embodiment of the present application, during the door opening process, the decorative panel 400 can slide in the direction away from the rotating side of the door body 100, thereby avoiding interference between the door assembly and the side wall of the cabinet when the door assembly is opened and closed. By installing the first magnetic member 310 on the second slider 220 and the second magnetic member 320 on the decorative panel 400, when the first magnet moves with the second slider 220, due to the repulsive force, a non-contact synchronous movement is achieved between the second magnetic member 320 and the first magnetic member 310, avoiding jamming during the opening and closing process of the door assembly.

[0049] It can be understood that the second slider 220 is slidably connected to the door body 100, and the second slider 220 can drive the decorative panel 400 installed with the second magnetic member 320 to slide through the first magnetic member 310. When the user opens the door, the first magnetic member 310 will push the second magnetic member 320, enabling the decorative panel 400 to smoothly move along the movement direction of the door body 100 without direct contact or relying on a mechanical transmission device.

[0050] In one embodiment, the magnetic properties of the first magnetic member 310 and the second magnetic member 320 are the same. Of course, in some embodiments, the magnetic properties of the first magnetic member 310 and the second magnetic member 320 are different. Specifically, the overall volume of the first magnetic member 310 can be larger than the volume of the second magnetic member 320, such that the magnetic force of the first magnetic member 310 is greater than that of the second magnetic member 320, or the magnetic force structure of the first magnetic member 310 is more compact, such that the magnetic force of the first magnetic member 310 is greater than that of the second magnetic member 320.

[0051] At least one of the first magnetic member 310 and the second magnetic member 320 can be a permanent magnet made of hard magnetic materials (such as neodymium iron boron, cobalt iron boron, etc.). At least one of the first magnetic member 310 and the second magnetic member 320 can also be an electromagnet that is activated by an electric current and generates a magnetic field, and is composed of a winding (coil) and a magnetic material.

[0052] According to an embodiment of the present application, the magnetic assembly 300 includes a third magnet 330, the third magnet 330 is installed on the decorative plate 400, the first magnetic member 310 is located between the second magnetic member 320 and the third magnet 330, and the magnetic pole direction of the third magnet 330 is opposite to that of the first magnetic member 310.

[0053] It can be understood that the third magnet 330 is located on the other side of the second magnetic member 320 relative to the first magnetic member 310, ensuring that the first magnetic member 310 can be subjected to the repulsive forces of the second magnetic member 320 and the third magnet 330. The magnetic pole direction of the third magnet 330 is opposite to that of the first magnetic member 310, and the first magnetic member 310 is located between the second magnetic member 320 and the third magnet 330, which can form a more stable magnetic field environment. When the first magnetic member 310 moves with the second slider 220, due to the repulsive force between it and the third magnet 330, the decorative plate 400 will be subjected to the bidirectional repulsive forces from the first magnetic member 310 and the third magnet 330 during the sliding process. The decorative plate 400 can move more stably in the direction away from the rotating side of the door body 100. This design helps to improve the stability of the opening and closing process of the door assembly, makes the movement of the decorative plate 400 smoother, reduces the phenomenon of jamming and jitter, and further improves the user experience.

[0054] It should be noted that the magnetic properties of the third magnet 330 and the first magnetic member 310 can be the same or different.

[0055] Similarly, the third magnet 330 can be a permanent magnet made of hard magnetic materials (such as neodymium iron boron, cobalt iron boron, etc.). The third magnet 330 can also be an electromagnet that is activated by an electric current and generates a magnetic field, and is composed of a winding (coil) and a magnetic material.

[0056] According to an embodiment of the present application, the first magnetic member 310, the second magnetic member 320, and the third magnet 330 are all located on the same straight line.

[0057] It can be understood that the first magnetic member 310, the second magnetic member 320, and the third magnet 330 arranged in a straight line can form a more stable and concentrated magnetic field, which helps to ensure that the decorative panel 400 is subjected to a uniform and stable repulsive force during the sliding process, thereby improving the smoothness and fluidity of the sliding of the decorative panel 400. Moreover, since the first magnetic member 310, the second magnetic member 320, and the third magnet 330 are on the same straight line, the installation and debugging processes become simpler and more intuitive, reducing the assembly difficulty.

[0058] According to an embodiment of the present application, at least one of the first magnetic member 310, the second magnetic member 320, and the third magnet 330 is detachably connected.

[0059] It can be understood that when a certain magnet (the first magnetic member 310, the second magnetic member 320, and the third magnet 330) has a performance decline or is damaged, the magnet can be separately disassembled for repair or replacement without disassembling the entire door assembly. This not only improves the repair efficiency but also reduces the repair cost. The detachably connected first magnetic member 310, second magnetic member 320, and third magnet 330 make the door assembly have better compatibility and expandability. For example, it is possible to easily replace the magnet with different specifications or performances to adapt to different application scenarios or requirements.

[0060] One of the first magnetic member 310, the second magnetic member 320, and the third magnet 330 can achieve detachable connection by fixing methods such as screws and buckles. Of course, other detachable connection methods can also be used for installation.

[0061] According to an embodiment of the present application, the number of the magnetic assemblies 300 is multiple, and the multiple magnetic assemblies 300 are arranged at intervals along the height direction of the door body 100. It can be understood that the arrangement of the multiple magnetic assemblies 300 enables the door body 100 to have corresponding support and fixing points in the height direction, thereby improving the overall stability of the door body 100. When the door body 100 slides, the interval arrangement of the multiple magnetic assemblies 300 can reduce the friction force, making the door body 100 slide more smoothly. At the same time, due to the interaction between the respective magnetic assemblies 300, the gravity of the door body 100 can also be balanced to a certain extent, making the sliding more stable.

[0062] The multiple magnetic assemblies 300 can be evenly distributed in the height direction of the door body 100, improving the overall stability of the door body 100. Or, the multiple magnetic assemblies 300 can be unevenly distributed according to the shape and size of the door body 100, and no specific limitation is made here.

[0063] According to an embodiment of the present application, the sliding door mechanism 200 includes a first slider 210, a connecting rod 230, and a transmission member 240. The first slider 210 is slidably mounted on the door body 100; one end of the connecting rod 230 is rotatably connected to the first slider 210, and the other end is rotatably connected to the box body 500; the transmission member 240 is drivingly connected to the first slider 210 and the second slider 220. When opening the door, the connecting rod 230 rotates to drive the first slider 210 to slide, and drives the second slider 220 to slide in a direction away from the rotating side through the transmission member 240.

[0064] It can be understood that through the transmission of the connecting rod 230, the first slider 210, and the second slider 220, the decorative panel 400 can slide relative to the door body 100, thereby avoiding interference during the opening and closing of the door assembly. The structure is simple and the assembly is convenient, which is beneficial to improving the assembly efficiency of the door assembly.

[0065] According to an embodiment of the present application, the first slider 210 and the second slider 220 are both provided with tooth grooves. The transmission member 240 includes a first gear 241, a transmission gear 243, and a second gear 242. The first gear 241 meshes with the first slider 210; the second gear 242 meshes with the second slider 220; the transmission gear 243 is drivingly connected to the first gear 241 and the second gear 242.

[0066] It can be understood that when opening the door, as the door body 100 rotates relative to the box body 500, the connecting rod 230 drives the first slider 210 to slide relative to the door body 100. The tooth groove of the first slider 210 can drive the transmission member 240 (the first gear 241, the transmission gear 243, and the second gear 242) to rotate. The second gear 242 meshes with the second slider 220, thereby driving the second slider 220 to slide. Due to the repulsive force, a non-contact synchronous movement is achieved between the second magnetic member 320 and the first magnetic member 310, realizing the relative movement between the door body 100 and the decorative panel 400.

[0067] When closing the door, as the door body 100 rotates relative to the box body 500, the connecting rod 230 drives the first rack to slide in the opposite direction relative to the door body 100, thereby driving the decorative panel 400 to slide in the opposite direction, realizing the relative movement between the door body 100 and the decorative panel 400, and ensuring that the decorative panel 400 can be normally closed.

[0068] It should be noted that through the intermediate transmission of the transmission gear 243, the rotation directions of the first gear 241 and the second gear 242 are ensured to be the same, realizing simultaneous clockwise rotation or counterclockwise rotation when opening the door, and simultaneous counterclockwise rotation or clockwise rotation when closing the door.

[0069] In one embodiment, the door body 100 is provided with a first slide rail 130 and a second slide rail 140. The first slide rail 130 and the second slide rail 140 are respectively installed on opposite sides of the door body 100. The first slider 210 is slidably connected to the first slide rail 130, and the second slider 220 is slidably connected to the second slide rail 140. By sliding the first slider 210 on the first slide rail 130 and the second slider 220 on the second slide rail 140, the smoothness of the door body 100 relative to the plate body 110 during the sliding process can be ensured, and the shaking and noise can be reduced.

[0070] In one embodiment, the first slide rail 130 is provided with one of a first limiting portion 131 and a first limiting groove 211, and the first slider 210 is provided with the other of the first limiting portion 131 and the first limiting groove 211. The first limiting portion 131 and the first limiting groove 211 are snap-connected.

[0071] It should be noted that the shape of the first limiting portion 131 can be an I-shaped structure, or a spindle shape or other limiting structures. The first limiting groove 211 is arranged corresponding to the shape of the first limiting portion 131.

[0072] In one embodiment, the second slide rail 140 is provided with one of a second limiting portion 141 and a second limiting groove 411, and the second slider 220 is provided with the other of the second limiting portion 141 and the second limiting groove 411. The second limiting portion 141 and the second limiting groove 411 are snap-connected.

[0073] It should be noted that the shape of the second limiting portion 141 can be an I-shaped structure, or a spindle shape or other limiting structures. The second limiting groove 411 is arranged corresponding to the shape of the second limiting portion 141.

[0074] According to an embodiment of the present application, the door body 100 includes a plate body 110 and a mounting portion 120. An installation space for the sliding door mechanism 200 is formed between the plate body 110 and the mounting portion 120. A third slide rail 410 is installed on a side of the mounting portion 120 facing the decorative plate 400. The decorative plate 400 is slidably connected to the third slide rail 410.

[0075] It can be understood that the plate body 110 constitutes the basic shape and appearance of the door body 100. The mounting portion 120 is connected to the plate body 110. An installation space for the sliding door mechanism 200 is formed between the mounting portion 120 and the plate body 110. The mounting portion 120 can be designed as a structure integrally formed with the plate body 110, or can be fixedly connected to the plate body 110 by welding, bolt connection, etc.

[0076] The third slide rail 410 is installed on one side of the installation part 120 facing the decorative plate 400 to ensure that the decorative plate 400 can slide smoothly. The decorative plate 400 is provided with a third limiting part or a third limiting groove matching the third slide rail 410 to ensure that the decorative plate 400 can be stably installed on the third slide rail 410.

[0077] For the refrigeration equipment according to the embodiment of the second aspect of the present application, please refer to Figure 4 , the refrigeration equipment includes a box body 500 and the door assembly of the above refrigeration equipment. The box body 500 forms an accommodation space, and the door assembly is rotatably arranged on the box body 500 to open or close the accommodation space.

[0078] It can be understood that the door assembly is arranged on the box body through a rotating mechanism (such as a hinge, a rotating shaft, etc.). By rotating, the accommodation space can be opened or closed, which is convenient for users to store and retrieve items. When rotating, the decorative plate and the door body can have relative displacement, avoiding interference during the opening and closing of the door assembly, and greatly improving the user experience.

[0079] It should be noted that since the refrigeration equipment of the present application includes the above door assembly, it has all the technical effects of the above door assembly, which will not be elaborated here.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications, or equivalent replacements of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should all be covered within the scope of the claims of the present application.
