Description

Technical Field

[0001] This invention belongs to the field of dishwasher technology, specifically relating to a support assembly for a dishwasher shelf and a dishwasher having the support assembly. Background Technology

[0002] Dishwashers can automatically clean bowls, chopsticks, plates, dishes, knives, forks, and other utensils. The dish rack is one of the important components of a dishwasher, and its main function is to support the tableware placed inside the dishwasher so that the dishwasher can wash the tableware.

[0003] Everyday tableware comes in a variety of shapes and sizes, but the distance between the support teeth on most dishwasher racks cannot be adjusted, making it impossible to accommodate tableware of different shapes and sizes. This affects the space utilization of the dishwasher rack, and the tilt angle of the tableware is not adjustable, which affects the washing effect.

[0004] Patent CN201610423397.4 discloses a support assembly for a dishwasher shelf, including a fixed frame and support teeth. The support teeth include a support part and a sleeve connected to the support part. The sleeve is rotatably fitted onto the fixed frame. The outer peripheral wall of the fixed frame and the inner peripheral wall of the sleeve are respectively provided with a first tooth structure and a second tooth structure. The first tooth structure meshes with the second tooth structure and can rotate relative to each other to be positioned in any of a plurality of meshing positions, so that the dishwasher shelf can be adjusted to accommodate utensils of different sizes. However, the structure of the support assembly is complex, resulting in low adjustment efficiency and a limited number of meshing positions. This limits the rotation angle of the teeth to the meshing positions of the first / second tooth structures, allowing adjustment only at fixed angle settings, and the distance between adjacent settings is fixed, making it difficult to adapt to irregularly shaped or significantly different sized tableware.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] To address the aforementioned problems in the prior art, this invention proposes a dishwasher shelf support assembly that offers high adjustability, a simple structure, reduced manufacturing and assembly costs, convenient operation, and high adjustment efficiency.

[0007] To achieve the above-mentioned objectives, the present invention employs the following technical solution: A dishwasher shelf support assembly includes: A mounting bracket, which is installed on the dishwasher shelf; A support frame that supports tableware and can be rotated when squeezed by tableware; A hinge structure is provided between the support frame and the fixed frame. The hinge structure has a hinge shaft provided on one of the support frame and the fixed frame, and a hinge hole opened on the other of the support frame and the fixed frame. The hinge shaft and the hinge hole are matched and arranged.

[0008] In some embodiments of this application, the hinge shaft and the hinge hole are interference-fitted.

[0009] In some embodiments of this application, a damping sleeve is provided between the hinge shaft and the hinge hole, and the damping sleeve is sleeved on the hinge shaft.

[0010] In some embodiments of this application, a damping layer is provided on the outside of the hinge shaft and / or the inside of the hinge hole.

[0011] In some embodiments of this application, a positioning block is provided on the fixed frame for positioning the support frame. The positioning block extends along the fixed frame toward the support frame, and the lower part of the support frame abuts against the positioning block to achieve positioning.

[0012] In some embodiments of this application, the bracket assembly has two parallel fixed frames and a plurality of support frames spaced apart between the two fixed frames, with the lower ends of the support frames respectively hinged to the two support frames.

[0013] In some embodiments of this application, a hinge hole is provided on the fixed frame, the hinge shaft is fixed to the lower part of the support frame, and both ends of the hinge shaft protrude outward from the support frame.

[0014] In some embodiments of this application, the lower part of the support frame is provided with mounting holes for fixing the hinge shaft, and the two ends of the hinge shaft are respectively located in the two hinge holes.

[0015] In some embodiments of this application, the hinge shaft has a shaft body and a fastening head located at the end of the shaft body. The diameter of the fastening head is larger than the diameter of the shaft body. A receiving groove for accommodating the fastening head is provided at the end of the hinge hole, and the fastening head is located in the receiving groove.

[0016] In some embodiments of this application, the hinge shaft is fixed on the fixed frame, and the support frame is provided with a hinge hole, with the hinge shaft located within the hinge hole.

[0030] See Figures 1-8 This is an embodiment of a dishwasher shelf support assembly proposed in this utility model. A dishwasher shelf support assembly 100 includes: a fixed frame 10 and a support frame 20. The fixed frame 10 is installed on the dishwasher shelf 200, and the support frame 20 is used to support the tableware 300. The support frame 20 can be adapted to rotate after being squeezed by the tableware 300.

[0031] In this embodiment, a hinge structure 30 is provided between the support frame 20 and the fixed frame 10. The hinge structure 30 has a hinge shaft 31 and a hinge hole 32. The hinge shaft 31 is fixedly mounted on one of the support frame 20 and the fixed frame 10, and the hinge hole 32 is mounted on the other. The hinge shaft 31 and the hinge hole 32 are matched. When the tableware 300 is placed between two adjacent support frames 20, the squeezing force can directly drive the support frame 20 to rotate around the hinge shaft 31. The angle adjustment range is entirely determined by the shape and size of the tableware. When a shallow plate is placed, the support frame 20 maintains a small angle of inclination after slight squeezing; when a deep bowl or long-handled spoon is placed, the support frame 20 can rotate to a larger angle as the squeezing force increases, achieving stepless adjustment and covering a wide range of everyday tableware. The manufacturing difficulty is low; during assembly, only the hinge shaft 31 needs to be inserted into the hinge hole 32 to complete the connection, greatly improving production efficiency. Users only need to place the tableware directly on the support frame 20, and the pressure of the tableware 300 itself will drive the support frame 20 to rotate around the hinge axis 31 to the appropriate angle without the need for manual adjustment of the position; when taking the tableware out or putting it in, the support frame 20 can automatically reset as the tableware 300 is removed.

[0032] In some embodiments of this application, the hinge shaft 31 and the hinge hole 32 are interference-fitted. This interference fit creates a certain amount of friction between the hinge shaft 31 and the hinge hole 32, ensuring that the support frame 20 can be rotated and adjusted when squeezed by the tableware 300, while also allowing it to remain stably at the current angle after adjustment. The interference fit allows the two to fit tightly together, forming a stable connection structure, distributing the pressure of the tableware weight on the hinge area, and avoiding wear or deformation caused by local stress concentration. The interference fit does not require additional locking components; only the dimensional tolerances of the hinge shaft 31 and the hinge hole 32 need to be controlled to achieve a tight fit through press fitting, making the assembly process simpler and more efficient.

[0033] In some embodiments of this application, a damping sleeve is provided between the hinge shaft 31 and the hinge hole 32. The damping sleeve is not shown in the accompanying drawings and is fitted onto the hinge shaft 31. The damping sleeve can be made of elastic materials such as silicone or rubber. The damping sleeve can precisely control the friction force at the hinge joint by adjusting its own hardness and thickness, avoiding both over-tightening and over-loosening adjustments that may occur with interference fits. The elastic material of the damping sleeve can effectively absorb vibration energy, reducing the impact of vibration on the hinge shaft 31 and hinge hole 32, while also buffering the instantaneous force on the support frame. Interference fits require high dimensional accuracy of the parts. If there are slight dimensional errors in the hinge shaft 31 or hinge hole 32, it may lead to insufficient interference and loose fit. The damping sleeve can compensate for these dimensional deviations through its own elasticity, ensuring a tight fit, reducing the requirements for part machining accuracy, and improving the assembly compatibility of different batches of parts. In some embodiments of this application, a damping layer is provided on the outer side of the hinge shaft 31, or on the inner side of the hinge hole 32, or on both the outer side of the hinge shaft 31 and the inner side of the hinge hole 32. The damping layer can be a coating, a patch structure, etc., and can be directly provided on the outer side of the shaft or the inner side of the hole. This allows for flexible design to fit the component shape without requiring additional assembly space for the damping sleeve. The damping layer can be tightly bonded to the surface of the hinge shaft 31 or the hinge hole 32 through processes such as coating or injection molding, forming a more uniform friction contact surface and avoiding uneven damping force caused by assembly deviations of the damping sleeve. If damping layers are provided on both the outer side of the shaft and the inner side of the hole, the damping force can be controlled by superimposing two damping structures: this can be achieved by adjusting the thickness or material of a single damping layer, resulting in a more flexible range of damping force adjustment.

[0034] In some embodiments of this application, the support assembly 100 has two parallel fixed frames 10 and a plurality of support frames 20 spaced apart between the two fixed frames 10. The lower ends of the support frames 20 are respectively hinged to the two parallel support frames 20. The two parallel fixed frames 10 form a symmetrical support frame, providing stable support for the entire support assembly. The lower ends of the support frames 20 are respectively hinged to the two fixed frames 10, so that each support frame 20 forms a load-bearing structure with support at both ends. The hinge points at both ends can also share the load, preventing the support frame 20 from breaking or tilting due to excessive force at a single point.

[0035] In some embodiments of this application, a hinge hole 32 is provided on the fixed frame 10, and a hinge shaft 31 is fixed to the lower part of the support frame 20, with both ends of the hinge shaft 31 protruding outward from the support frame 20. A mounting hole 21 is provided at the lower part of the support frame 20 for fixing the hinge shaft 31, with both ends of the hinge shaft 31 located within the two hinge holes 32 respectively. The hinge shaft 31 is installed through the fixed frame 10. The hinge shaft 31 is fixed within the mounting hole 21 at the lower part of the support frame 20, and both ends protrude outward and are installed through the hinge holes 32 of the fixed frame 10, forming a symmetrical support structure. This ensures that both ends of the support frame 20 are always tightly connected to the fixed frame, ensuring that each support frame 20 can be stably maintained at the appropriate angle, providing reliable support for the tableware 300. The through-type structure at both ends of the hinge shaft 31 can naturally ensure the parallelism of the two fixed brackets 10 and the horizontality of the support bracket 20, reduce assembly accuracy errors, ensure that all support brackets 20 are on a uniform assembly datum, and avoid affecting the overall use effect due to the tilt of individual support brackets.

[0036] In some embodiments of this application, a positioning block 11 is provided on the fixed frame 10 for positioning the support frame 20. The positioning block 11 extends along the fixed frame 10 towards the support frame 20. The lower part of the support frame 20 abuts against the positioning block 11 for positioning. The support frame 20 is assembled by installing and fixing the hinge shaft 31. The positioning block 11 extends along the fixed frame towards the support frame 20 and allows the lower part of the support frame 20 to abut against the positioning block. This provides a clear positional reference for the support frame 20 in the early stages of assembly, avoiding offset or tilting of the support frame due to lack of positioning. It also ensures that the mounting hole 21 at the bottom of the support frame 20 is precisely aligned with the hinge hole 32 on the fixed frame 10, avoiding problems such as difficulty in inserting the hinge shaft and assembly jamming due to misalignment of the holes. At the same time, it ensures that multiple support frames 20 are installed at the same height and with uniform spacing, improving the assembly accuracy of the entire bracket assembly. The positioning block 11 abuts against the lower part of the support frame 20. Before the hinge shaft 31 is fully fixed, it can temporarily support the weight of the support frame 20 to prevent it from shaking or falling during assembly and reduce the difficulty of assembly operation. After the hinge shaft 31 is fixed, the positioning block 11 can work with the hinge shaft 32 to bear the weight of the support frame 20 and the tableware, which greatly improves the structural stability. In some embodiments of this application, the hinge shaft 31 has a shaft body 311 and a fastening head 312 located at the end of the shaft body 311. The diameter of the fastening head 312 is larger than the diameter of the shaft body 311. A receiving groove 321 for accommodating the fastening head 312 is provided at the end of the hinge hole 32, and the fastening head 312 is located in the receiving groove 321. The diameter of the fastening head 312 is larger than that of the shaft body 311, and the corresponding receiving groove 321 can stably accommodate the fastening head 312, forming an end limiting structure, which is beneficial to the fastening of the hinge shaft 31 during installation and fixation.

[0037] In some other embodiments of this application, the hinge shaft 31 may also be fixed on the fixing frame 10, and the support frame 20 is provided with a hinge hole, with the hinge shaft located in the hinge hole.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
