This is only for convenience of description and does not indicate or imply that the relevant devices or components must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, ordinal numbers such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Furthermore, in order to more clearly show the core technical solution of the present invention, the description of the well-known structure of the dishwasher is omitted below. However, this omission is only for the convenience of description and does not mean that the dishwasher can be without these structures.

[0027] As Figures 1-5 shown, the present invention provides a sliding door hinge, including: a flipping plate 1, on which a rack 5 is slidably arranged along a first direction; a rotating plate 6, the flipping plate 1 and the rotating plate 6 are rotatably connected through a first rotating shaft 7, one end of the rotating plate 6 is provided with a first tooth portion 8 around the first rotating shaft 7, and the first tooth portion 8 meshes with the first meshing portion of the rack 5; when the flipping plate 1 rotates around the first rotating shaft 7, the first tooth portion 8 pushes the rack 5 to slide along the first direction; a sliding member 9, the sliding member 9 includes a connecting portion 10 and a sliding portion 11, the connecting portion 10 is connected to the rack 5 through a transmission assembly 12, and the sliding portion 11 is used to connect to a door body 26. After the rack 5 slides, the door body 26 is driven by the sliding member 9 to move in the same direction. The sliding member 9 is configured such that when the angle between the flipping plate 1 and the rotating plate 6 gradually increases, the sliding member 9 moves away from the first rotating shaft 7, and when the angle between the flipping plate 1 and the rotating plate 6 gradually decreases, the sliding member 9 moves closer to the first rotating shaft 7.

[0028] During operation, the flipping plate 1 rotates around the first rotating shaft 7, and the first tooth portion 8 on the rotating plate 6 rotates relative to the flipping plate 1. The teeth thereon push the rack 5, causing the rack 5 to slide in the first direction. After the rack 5 slides, it drives the sliding member 9 to move in the same direction through the transmission assembly 12, and further drives the door body 26 connected to the sliding portion 11 to slide in the same direction as the rack 5.

[0029] As shown in the figure, the X direction in the figure represents the first direction. Figure 1 The figure shows the relative positional relationship between the flipping plate 1 and the rotating plate 6 when the door body 26 is closed. When opening the door body 26, the flipping plate 1 rotates counterclockwise around the first rotating shaft 7, and the first tooth portion 8 pushes the rack 5 to slide upward in the first direction. After the rack 5 slides, it drives the sliding member 9 to slide upward through the transmission assembly 12, thereby driving the door body 26 to slide upward. After the door body 26 slides upward, the bottom edge of the door body 26 is displaced from the position of the cabinet body or other external objects, so that the door body 26 will not collide with the cabinet body or other external objects. Figure 5 The figure shows the relative positional relationship between the flipping plate 1 and the rotating plate 6 when the door body 26 is open. When closing the door body 26, the flipping plate 1 rotates clockwise around the first rotating shaft 7 and gradually approaches the rotating plate 6. The first tooth portion 8 pushes the rack 5 to slide downward in the first direction. After the rack 5 slides, it drives the sliding member 9 to slide downward through the transmission assembly 12, thereby driving the door body 26 to slide downward until the closed position.

[0030] In this embodiment, in order to solve the problem that the existing door hinge will cause interference between the door body 26 and the cabinet body or other external objects when the door body 26 is opened and closed, a door body 26 that can slide with the opening and closing is provided. When opened, it slides upward to avoid the collision of its bottom edge with the cabinet body or other external objects. When closed, it slides downward to return to the closed position. Since the door body 26 can slide, the gap between the door body 26 and the cabinet body or external objects can be appropriately reduced, taking into account both practicality and aesthetics.

[0031] Further, as Figure 2 shown, the transmission assembly 12 includes: a first transmission wheel 13 and a second transmission wheel 14. The first transmission wheel 13 and the second transmission wheel 14 are coaxially rotatably arranged on the flipping plate 1, and the first transmission wheel 13 meshes with the second engagement portion of the rack 5; a third transmission wheel 15 is arranged on one side of the second transmission wheel 14 along the first direction, and a toothed belt 16 is sleeved between the second transmission wheel 14 and the third transmission wheel 15; the toothed belt 16 has a transmission area, and the moving direction of the transmission area is the same as the moving direction of the rack 5. The connecting portion 10 is arranged on the transmission area and moves with the transmission area.

[0032] When the door body 26 is opened, the flip plate 1 rotates counterclockwise around the first rotating shaft 7, and the first tooth part 8 pushes the rack 5 to slide upward in the first direction. After the rack 5 slides, it drives the first transmission wheel 13 to rotate clockwise. The first transmission wheel 13 drives the second transmission wheel 14 to rotate clockwise, thereby driving the third transmission wheel 15 and the toothed belt 16 to rotate clockwise. The toothed belt 16 between the second transmission wheel 14 and the third transmission wheel 15 has upper and lower parts. The lower toothed belt 16 moves upward in the first direction, so the lower toothed belt 16 is the transmission area. The connecting part 10 is arranged on the transmission area and moves upward with the transmission area, driving the door body 26 to slide out.

[0033] When the door body 26 is closed, the flip plate 1 rotates clockwise around the first rotating shaft 7 and gradually approaches the rotating plate 6. The first tooth part 8 pushes the rack 5 to slide downward in the first direction. After the rack 5 slides, it drives the first transmission wheel 13 to rotate counterclockwise. The first transmission wheel 13 drives the second transmission wheel 14 to rotate counterclockwise, thereby driving the third transmission wheel 15 and the toothed belt 16 to rotate counterclockwise. The transmission area moves downward in the first direction, and the connecting part 10 moves downward with the transmission area, driving the door body 26 to retract to the closed position.

[0034] The rack 5 has a first meshing part for meshing with the first tooth part 8 and a second meshing part for meshing with the first transmission gear 13. The sizes of the teeth in the first meshing part and the second meshing part can be set according to actual situations; the sizes of the teeth in the first meshing part and the second meshing part can be the same or different.

[0035] Further, as Figure 1 shown, the flip plate 1 includes: a first support plate 2 and a second support plate 3 for supporting the transmission assembly 12. The first transmission wheel 13, the second transmission wheel 14, and the third transmission wheel 15 are all arranged on the first support plate 2. A chute 4 is arranged between the first support plate 2 and the second support plate 3. The rack 5 is arranged in the chute 4. The first rotating shaft 7 is arranged on the second support plate 3. The first tooth part 8 meshes with the first meshing part in the chute 4.

[0036] In this embodiment, a bottom plate can also be arranged between the first support plate 2 and the second support plate 3. The first support plate 2, the second support plate 3, and the bottom plate jointly form the chute 4. The rack 5 is arranged on the bottom plate.

[0037] Further, the sliding door hinge further includes: a cover plate 18. The cover plate 18 is arranged on the side of the first support plate 2 away from the second support plate 3. A guide groove 19 is arranged on the cover plate 18 along the first direction. The sliding part 11 slides in the guide groove 19. The guide groove 19 can limit the sliding direction of the sliding part 11, making the sliding of the sliding part 11 smoother and more stable.

[0038] Further, as Figure 3As shown, a transmission space is formed between the cover plate 18 and the first support plate 2. The second transmission wheel 14, the toothed belt 16, the third transmission wheel 15, and the connecting portion 10 are all located within the transmission space. The sliding portion 11 is provided on the side of the connecting portion 10 away from the transmission space, and the sliding portion 11 passes through the guiding groove 19 and is connected to the door body 26.

[0039] Furthermore, as Figure 4 shown, connecting teeth are provided on the connecting portion 10 for meshing with the teeth in the transmission area. In addition to the meshing method, the connecting portion 10 can also be installed on the connecting portion 10 in other ways, such as snap connection, etc.

[0040] Furthermore, as Figure 4 shown, mounting holes 20 are provided on the connecting portion 10 for mounting the sliding portion 11. The mounting holes 20 can be threaded holes, and the sliding portion 11 can have an external threaded portion, and the external threaded portion can be screwed into the mounting holes 20.

[0041] Furthermore, as Figures 3-4 shown, a baffle 21 and a stopper 22 are sequentially arranged on the side of the connecting portion 10 facing the first support plate 2 along the first direction. The baffle 21 is close to the second transmission wheel 14, and an elastic member 23 is provided between the baffle 21 and the stopper 22. A pressing plate 24 is provided on the side of the first support plate 2 facing the cover plate 18. During the process of the connecting portion 10 sliding towards the second transmission wheel 14, after the baffle 21 passes the pressing plate 24, the pressing plate 24 gradually compresses the elastic member 23. The baffle 21 is used to prevent the elastic member 23 from coming out between the baffle 21 and the stopper 22, and the pressing plate 24 is used to squeeze the elastic member 23. The elastic member 23 can be a spring.

[0042] During the closing process of the door body 26, the connecting portion 10 slides along the first direction towards the second transmission wheel 14. When the baffle 21 passes the pressing plate 24, the pressing plate 24 compresses the elastic member 23 in time. After the door body 26 is closed, the elastic member 23 is in a compressed state. After the door lock is unlocked, the elastic force of the elastic member 23 exerts a force on the sliding member 9 to slide upward along the first direction, driving the door body 26 to slide upward, and driving the flip plate 1 to rotate counterclockwise through the transmission assembly 12, assisting in opening the door body 26, and eliminating the need for the user to manually apply an opening force.

[0043] Due to the relatively heavy weight of the door body 26, the sudden opening and falling of the door body 26 impose a relatively large impact on the door hinge, which will increase the wear of the hinge and may even cause injury to the user. To avoid this problem, an outer baffle 21 can also be provided on the side of the blocking member 22 close to the third driving wheel 15, and an outer elastic member 23 is provided between the outer baffle 21 and the blocking member 22. At the same time, an outer pressing plate 24 is provided on the side of the first support plate 2 facing the cover plate 18. The outer pressing plate 24 is located on the side of the pressing plate 24 close to the third driving wheel 15. During the sliding process of the connecting portion 10 towards the third driving wheel 15, after the outer baffle 21 passes through the outer pressing plate 24, the outer pressing plate 24 gradually compresses the outer elastic member 23.

[0044] During the opening process of the door body 26, the connecting portion 10 slides towards the third driving wheel 15. After the outer baffle 21 passes through the outer pressing plate 24, the outer pressing plate 24 gradually compresses the outer elastic member 23. In this way, during the falling process of the door body 26, the deformation of the outer elastic member 23 becomes larger and larger, which can make the door body 26 fall slowly, reduce the impact on the hinge caused by the sudden fall of the door body 26, and avoid injury to the user caused by the sudden fall of the door body 26.

[0045] Furthermore, as Figure 5 shown, the radius of the second driving wheel 14 is greater than the radius of the first driving wheel 13. In this way, when the first driving wheel 13 rotates by the same angle, the sliding member 9 can be driven to slide a longer distance; in actual use, the radius sizes of the second driving wheel 14 and the first driving wheel 13 can be selected according to the actual situation.

[0046] A dishwasher, as Figure 6 shown, includes: a main body 25 and a door body 26. The door body 26 includes an intermediate door panel 27 and an outer door panel 28. The outer door panel 28 is slidably provided on the side of the intermediate door panel 27 away from the main body 25; the dishwasher further includes the sliding door hinge of any one of the above. One end of the rotating plate 6 away from the first rotating shaft 7 is provided on the main body 25; the flipping plate 1 is provided on the intermediate door panel 27. When the intermediate door panel 27 opens and closes, it drives the flipping plate 1 to rotate around the first rotating shaft 7; the sliding member 9 is connected to the outer door panel 28 and is used to drive the outer door panel 28 to slide in the first direction; the gravity of the door body 26 is configured to be able to drive the flipping plate 1 to rotate around the first rotating shaft 7. In this embodiment, the gravity of the door body 26 can overcome the pulling force of the hinge. After the door lock is unlocked, the door body 26 can slowly open under the action of gravity without the user having to manually apply an opening force, which is convenient for the user to use.

[0047] Since the vertical position of the rotating plate 6 may change during the actual application process, an installation shaft can be provided at one end of the rotating plate 6 away from the first rotating shaft 7. The installation shaft is installed in the slide rail on the main body 25, so that the installation shaft can realize height adjustment along the slide rail without affecting the rotation of the rotating plate 6 around the first rotating shaft 7.

[0048] Figure 6 In this case, a groove is provided on the middle door panel 27, and a boss is provided at the corresponding position on the outer door panel 28. The outer door panel 28 can slide relative to the middle door panel 27 by sliding the boss in the groove. However, this sliding method is not a limitation on the present invention. Without departing from the basic principle of the present invention, those skilled in the art can adopt other methods as long as the outer door panel 28 can slide relative to the middle door panel 27.

[0049] It should be noted that Figure 6 In this case, the shapes and connection relationships of the middle door panel 27 and the outer door panel 28 are only for reference and not a limitation on the present invention. Without departing from the basic principle of the present invention, those skilled in the art can adopt middle door panels 27 and outer door panels 28 of other shapes, which does not deviate from the principle of the present invention and thus will fall within the protection scope of the present invention. And Figure 6 In this case, only one sliding door hinge is provided on the left side. Those skilled in the art can also respectively provide a sliding door hinge on both the left and right sides according to actual needs.

[0050] Those skilled in the art can understand that although some of the embodiments described herein include certain features included in other embodiments rather than other features, the combination of the features of different embodiments means that it is within the scope of this application and forms different embodiments. For example, in the claims of this application, any one of the claimed embodiments can be used in any combination.

[0051] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
