Description

Technical Field

[0001] The utility model relates to the technical field of roller vibration external transmission structure, in particular to a roller vibration external transmission structure. Background Art

[0002] In the prior art, drums are often found in washing machines, blenders, screening machines, mixers, etc., and are used to load items and achieve corresponding purposes by rotating. For example, drum washing machines use the huge centrifugal force generated by the drum (i.e., inner drum) when rotating to drive the clothes to rotate, and the combined effect of detergent and water makes the clothes clean.

[0003] During the rotation of the drum, the center of gravity of the drum is unbalanced due to the objects loaded inside, and the drum often vibrates to a large extent. In order to reduce the risk of collision between the drum and the equipment support and adjacent structures (such as the outer drum and shell of the washing machine) during the vibration process, it is necessary to keep a gap between the drum and the adjacent structures, which invisibly increases the size and occupied space of the entire equipment, thereby reducing the effective volume inside the drum. Utility Model Content

[0004] The utility model provides a drum vibration output structure, which can reduce the vibration amplitude of the drum, thereby reducing the design distance between the drum and adjacent structures, thereby improving the space utilization of the drum or reducing the overall volume of the equipment.

[0005] The technical solution of the utility model is as follows:

[0006] A drum vibration transmission structure comprises a bracket, a drum and a vibration transmission component for transmitting the vibration of the drum to the bracket.

[0007] Furthermore, the vibration transmission component is arranged on a side of the bracket facing the drum and abuts against the drum.

[0008] Furthermore, the drum comprises a drum body and a drum connecting member fixedly connected to the drum body;

[0009] The vibration transmission component is in contact with the roller connecting piece.

[0010] Furthermore, the drum comprises a drum body, a drum connecting member fixedly connected to the drum body, and a supporting shaft tube for supporting the drum connecting member;

[0011] The vibration transmission component is in contact with the support shaft tube.

[0012] Furthermore, a first sealing rotation structure is provided between the roller connecting member and the vibration transmission assembly.

[0013] Furthermore, the roller connecting member is in contact with the supporting shaft tube, or a second sealing rotation structure is provided between the roller connecting member and the supporting shaft tube.

[0014] Further, the vibration transmission component is of an annular structure.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] Through the vibration transmission component, the present utility model transmits the vibration generated during the rotation of the drum to the bracket, and then absorbs the vibration through structures such as dampers and shock absorbers on the bracket to reduce the amplitude of the drum.

[0017] Thereby, the present utility model can reduce the spacing between the drum and adjacent structures, improve the space utilization rate of the drum, and can either choose to reduce the overall volume of the equipment or keep the equipment volume unchanged. By increasing the drum size, the drum volume carried within the limited space is maximally utilized. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1 to 2 shown, a drum vibration external transmission structure is mainly applied to a drum washing machine, and the drum is also called an inner cylinder. It can also be used in equipment such as mixers, sieving machines, and mixing machines.

[0026] The drum in this embodiment mainly includes a bracket 1 and a drum. The bracket 1 serves as the main frame of the device. A housing can be sleeved outside it, or a driving mechanism can be provided on the bracket 1 to drive the drum to rotate, which will not be elaborated in this embodiment. To achieve the vibration and absorption of the drum, a vibration transfer assembly 3 is provided in this embodiment for transferring the vibration of the drum to the bracket 1.

[0027] Specifically, the vibration transfer assembly 3 is arranged on the side of the bracket 1 facing the drum and abuts against or is fixedly connected to the drum, so as to fully transfer the vibration of the drum. And for the connection with the drum and the support of the drum, the drum in this embodiment includes two main parts: a cylinder body 21 and a drum connector 22 fixedly connected to the cylinder body 21. The drum connector 22 mainly functions to connect and support the cylinder body 21, and the cylinder body 21 serves as a container for accommodating items and rotating. And to improve the connection stability between the drum connector 22 and the cylinder body 21, a tubular structure is preferably used. While being structurally stable and space-saving, it has a larger contact area with the vibration transfer assembly 3, making the vibration transfer more sufficient (the transfer assembly 3 can extend to the outer wall or inner wall of the drum connector 22). Therefore, the specific component in contact with the vibration transfer assembly 3 is the drum connector 22.

[0028] In addition, for the convenience of assembly, maintenance, and ensuring the normal rotation of the drum, the drum connector 22 and the vibration transfer assembly 3 in this embodiment are not directly welded or connected in other ways, but are rotatably connected. And since there will be a gap at this place, therefore, to prevent the leakage of media such as solid, liquid, and gas between the drum connector 22 and the vibration transfer assembly 3, a first sealed rotating structure 4 is provided between the drum connector 22 and the vibration transfer assembly 3, such as setting a bearing and arranging a combination of seals such as water seals and air seals on both sides of the bearing.

[0029] Using the annular structure of the vibration transfer assembly 3, not only can various seals be adapted to seal the gap between the vibration transfer assembly 3 and the drum connector 22, but also the contact area with the drum connector 22 can be increased to fully transfer the vibration. Then the vibration is transferred to a shock-absorbing box 6 suspended at the top of the bracket 1 or an elastic damper 7 installed at the bottom of the bracket 1 (one end is connected to the bracket 1 and the other end is connected to the outer shell or the base), allowing these shock-absorbing structures to fully absorb the vibration brought by the rotation of the drum.

[0030] The cylinder body 21 and the drum connector 22 in this embodiment are supported by the vibration transfer assembly 3. To avoid shaking and other situations, the length of the drum connector 22 can be appropriately adjusted, or the contact and support area between the drum connector 22 and the vibration transfer assembly 3 can be increased, or additional support points can be provided on the bracket 1 to support the cylinder body 21 and the drum connector 22, which will not be elaborated in this embodiment.

[0031] Embodiment Two

[0032] As Figure 3 shown, the difference from the first embodiment is that in this embodiment, the drum not only includes a cylinder body 21 and a drum connecting member 22 fixedly connected to the cylinder body 21, but also a support shaft tube 5 for supporting the drum connecting member 22 is provided. The support shaft tube 5 serves as a medium of the bracket 1 and is connected to the drum, which can increase the supported area of the drum and improve the running stability of the drum.

[0033] Then, in a manner that the vibration transmission assembly 3 abuts against the support shaft tube 5 (the transmission assembly 3 can extend to the outer wall or the inner wall of the support shaft tube 5), the vibration of the drum is transmitted to the bracket 1 through the support shaft tube 5.

[0034] Similarly, in order to keep the drum rotating normally and then improve the sealing performance between the structural clearances, in this embodiment, the drum connecting member 22 and the support shaft tube 5 are in an abutting manner, or a second sealing rotating structure 8 such as a bearing is provided, and sealing structures such as water seals and air seals are provided on both sides of the bearing, so as to improve the running stability and sealing performance.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
