Description

Technical Field

[0001] The utility model relates to the technical field of drum support structures, and specifically, to a drum support structure. Background Art

[0002] In the prior art, drums often appear in equipment such as washing machines, mixers, screening machines, and mixing machines, and are used to load items and achieve corresponding purposes by rotating. For example, in a drum washing machine, the inner drum (i.e., the drum) rotates to drive the clothes to rotate by generating a huge centrifugal force, and the clothes are washed clean under the combined action of detergent and water.

[0003] Generally, a support shaft is arranged on a bracket to support the drum. However, the structure of the support shaft of the existing washing machine is usually not reasonably designed for the connection relationship with the inner drum. By adopting a linkage connection relationship to make the inner drum and the support shaft rotate synchronously, on the one hand, it increases the design and manufacturing difficulty of the support shaft, and potential problems in the connection and sealing structure of the support shaft need to be fully considered. On the other hand, the linkage between the inner drum and the support shaft makes it impossible for the support shaft to run asynchronously with the inner drum to stir the solid, liquid, and gas in the inner drum. Summary of the Utility Model

[0004] The utility model provides a drum support structure, which can make the inner drum and the support shaft run asynchronously, reduce the design requirements and manufacturing costs, and at the same time can use the support shaft to stir the solid, liquid, and gas in the inner drum to improve the washing effect.

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

[0006] A drum support structure includes an inner drum and a support shaft tube, and an asynchronous connection structure for making the inner drum and the support shaft tube rotate non-synchronously.

[0007] Further, the asynchronous connection structure includes a first rotating member sleeved on the support shaft tube, and an inner drum shaft tube for connecting the inner drum is sleeved on the first rotating member.

[0008] Further, an outer drum is included, a second rotating member is sleeved on the inner drum shaft tube, and an outer drum shaft tube for connecting the outer drum is connected to the second rotating member.

[0009] Further, a driving mechanism for driving the inner drum shaft tube to rotate is included.

[0010] Further, the driving mechanism includes a rotating wheel disc and a positioning piece. The rotating wheel disc is sleeved on the outer wall of the inner drum shaft tube, and both ends of the positioning piece are respectively embedded in the outer wall of the inner drum shaft tube and the inner wall of the connection hole of the rotating wheel disc.

[0011] Further, a bracket for supporting the support shaft tube is included.

[0012] Further, the cross-section of the bracket is in a "[-]" shape structure, and both ends of the bracket support the support shaft tube and the outer cylinder shaft tube simultaneously.

[0013] Further, the support shaft tube is a hollow structure and can be used to connect the inner cylinder.

[0014] Further, several damping dampers are connected to the bottom of the outer cylinder.

[0015] Further, both the first rotating member and the second rotating member are bearings.

[0016] The working principle and beneficial effects of the present utility model are as follows:

[0017] Through the asynchronous connection structure, the present utility model disengages the support shaft tube from the linkage relationship with the inner cylinder. The inner cylinder can rotate or remain stationary according to the usage needs on its own when the support shaft tube is stationary, which can reduce the requirements for sealing, connection, etc. at the support shaft tube. At the same time, when the inner cylinder rotates, the support shaft tube can be extended into the inner cylinder to interact with the solid, liquid, and gas inside the inner cylinder, improving the effect of functions such as laundry.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of the present utility model.

[0024] Embodiment 1:

[0025] As Figure 1-2As shown, a drum support structure mainly includes an inner drum 1 and a support shaft tube 2, and existing structures such as a housing and a driver are omitted. In order to realize the independent operation of the inner drum 1 and the support shaft tube 2, this embodiment is provided with an asynchronous connection structure for making the inner drum 1 and the support shaft tube 2 rotate asynchronously. The support shaft tube 2 is preferably a hollow structure and can be used to connect to the inner drum 1 to input solid, liquid, gas and other substances, assist in washing and drying, or play a stirring role, which plays an auxiliary role and improves the use effect of the washing machine.

[0026] Specifically, the asynchronous connection structure in this embodiment includes a first rotating member 12 sleeved on the support shaft tube 2, and the first rotating member 12 is sleeved with an inner cylinder shaft tube 11 for connecting the inner cylinder 1. The inner cylinder 1 cooperates with the first rotating member 12 through the inner cylinder shaft tube 11, so that the inner cylinder 1 rotates through the support of the support shaft tube 2.

[0027] At the same time, it also includes an outer drum 3, which is a common structure of a drum washing machine. In this embodiment, a second rotating member 32 is sleeved on the inner drum shaft tube 11, and the second rotating member 32 is connected to the outer drum shaft tube 31 for connecting the outer drum 3. The inner drum shaft tube 11 can be used to support the outer drum 3, and the second rotating member 32 can also make the outer drum 3 and the inner drum 1 move relatively independently, such as when the inner drum 1 rotates, the outer drum 3 remains stationary.

[0028] If the present embodiment needs to support the rotation of the shaft tube 2 or the outer tube 3 to play other functions, a driving structure can be provided separately, which will not be described in detail in the present embodiment.

[0029] At the same time, this embodiment also includes a driving mechanism for driving the inner cylinder shaft tube 11 to rotate. Specifically, the driving mechanism includes a rotating wheel 41 and a positioning piece 42. The rotating wheel 41 is sleeved on the outer wall of the inner cylinder shaft tube 11, and the two ends of the positioning piece 42 are respectively embedded in the outer wall of the inner cylinder shaft tube 11 and the inner wall of the connecting hole of the rotating wheel 41 (i.e., the keyway structure). The rotating wheel 41 (i.e., the driven wheel) is driven to rotate by the driver, thereby linking the inner cylinder 1 to rotate.

[0030] In addition, in order to support the structures such as the shaft tubes, the present embodiment further includes a bracket 5 for supporting the support shaft tube 2. And in order to improve the stability of the support, the cross section of the bracket 5 is designed to be a "["-shaped structure in the present embodiment, so that when the bracket 5 is placed, both ends of the bracket 5 can simultaneously support the support shaft tube 2 and the outer tube shaft tube 31, thereby improving the stability of the support shaft tube 2 and the outer tube 3, which is usually a fixed connection support method, but is not limited to setting a rotation structure, etc., to support the rotation of the support shaft tube 2 and the outer tube 3.

[0031] In this embodiment, as a preferred solution, the above-mentioned support shaft tube 2, inner tube shaft 11 and outer tube shaft 31 are all tubular structures and are sleeved in sequence, which improves compactness and reduces the occupied space. Moreover, the first rotating member 12 and the second rotating member 32 are preferably bearings, which have a compact structure, mature technology and can fully control costs.

[0032] Embodiment 2:

[0033] As Figure 3 shown, on the basis of Embodiment 1, several damping dampers 6 are connected to the bottom of the outer cylinder 3 in this embodiment, which can improve the damping effect at the outer cylinder 3 and, together with structures such as the bracket 5 and the support shaft tube 2, improve its stability and service life.

[0034] 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.
