Therefore, they should not be construed as limitations on this utility model.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To address the problems in existing drum washing machines where the gearbox is directly connected to the inner drum and relies on the cabinet structure for support, with the entire drive system supported and buffered by a cantilever beam, leading to strong vibration and noise, high requirements for cabinet rigidity and manufacturing precision, and low overall maintainability, this embodiment proposes a transmission device and garment processing equipment. The transmission device consists of a planetary gearbox 1, a belt 2, and a motor. The motor sequentially drives multiple drums within the garment processing equipment to rotate via the planetary gearbox 1 and belt 2. Specifically, the planetary gearbox 1 is located on the back plate of the garment processing equipment's cabinet 4. The pulley 20 is located outside the rear end of the output shaft of the inner drum 3. The planetary gearbox 1 is integrated with the motor, and the motor's output shaft is connected to a bearing seat inside the inner drum 3 via a bearing. The planetary gearbox 1 is connected to the pulley 20 via the belt 2. Under the action of the motor, the components in the planetary gearbox 1 rotate, thereby driving the pulley 20 to rotate at the corresponding speed.

[0030] By installing the transmission device in the garment processing equipment, the structural design of the garment processing equipment can be effectively optimized, the rigidity and manufacturing precision of the housing 4 in the equipment can be improved, and the vibration inside the equipment can be greatly reduced and the noise in the equipment can be reduced during the operation of the equipment, thereby improving the maintenance efficiency of each component inside the housing 4.

[0031] The planetary gearbox 1 includes a sun gear 11 and a planetary pinion 12, which are respectively connected to the output shaft of the corresponding driven inner cylinder 3 via belts 2 in a rotatable manner.

[0032] By setting up a two-stage gear system with a sun gear 11 and a planetary pinion 12, the structure of the planetary gearbox 1 can be simplified, the cost of the transmission device can be reduced, the structural stability of the transmission device can be improved, and it is also beneficial to realize the function of driving the two cylinders to rotate through the two-stage gears.

[0033] The planetary gearbox 1 includes a sun gear 11, planetary pinions 12, and an external gear ring 14. The sun gear 11, planetary pinions 12, and external gear ring 14 are all rotatably connected to the output shaft of the corresponding driven inner cylinder 3 via belts 2. At least one planetary pinion 12 is provided. When three planetary pinions 12 are provided, each of the three planetary pinions 12 is rotatably connected to the output shaft of the corresponding driven inner cylinder 3 via belts 2.

[0034] By employing the coordinated arrangement of the sun gear 11 (first-stage gear), the planetary pinions 12 (second-stage gear), and the external gear ring 14 (third-stage gear), the control of at least three cylinders by the same motor can be effectively achieved. Depending on the number of planetary pinions 12, the outer side of each planetary pinion 12 can be connected to the output shaft of the corresponding inner cylinder 3 via a belt 2, thereby driving different inner cylinders 3. This enhances the flexibility of the planetary gearbox 1 within the housing 4.

[0035] The planetary gearbox 1 also includes a planetary gear carrier 13. Three planetary pinions 12 are connected to the front end of the planetary gear carrier 13, and the rear end of the planetary gear carrier 13 is rotatably connected to the output shaft of the driven inner cylinder 3 via a belt 2. At this time, the planetary gearbox 1 includes a sun gear 11, planetary pinions 12, a planetary gear carrier 13, and an external gear ring 14. The sun gear 11, planetary pinions 12, planetary gear carrier 13, and external gear ring 14 are all fixed to the housing 4. The sun gear 11 is connected to the planetary gear carrier 13 and the external gear ring 14 via planetary pinions 12. The planetary pinions 12 are located outside the sun gear 11, and the external gear ring 14 is located outside the planetary pinions 12. The outer wall of the planetary pinions 12 meshes with or separates from the outer wall of the sun gear 11, and the inner wall of the external gear ring 14 meshes with or separates from the outer wall of the planetary pinions 12. Specifically, the outer side of the pulley 21 of the small cylinder belt is connected to the outer wall of the sun gear 11 via a belt. The outer side of the small cylindrical belt pulley 22 is connected to the outer wall of the planetary gear carrier 13 at the end away from the planetary pinion 12 via the belt 2. The outer side of the large cylindrical belt pulley 23 is connected to the outer wall of the external gear ring 14 via the belt.

[0036] Through the arrangement of components within the planetary gearbox 1, and based on existing clutch mechanisms, the synthesis and decomposition of motion achieved through different driving methods can be effectively realized, exhibiting flexibility and versatility. Furthermore, thanks to the high rigidity resulting from the integrated die-casting of the outer side of the inner cylinder 3 and the housing 4, the multi-inner-cylinder 3 structure, connected to the planetary gearbox 1 via the belt 2, provides a buffering effect, further reducing vibration and noise transmission. This ultimately enhances user satisfaction.

[0037] A garment processing device includes a transmission mechanism disposed within the device. The device comprises three inner cylinders 3, each consisting of a small cylinder 31, a small cylinder 32, and a large cylinder 33. The small cylinder 31 is driven by a sun gear 11 via a belt 2; the small cylinder 32 is driven by a planetary pinion 12 via a planetary gear carrier 13 via a belt 2; and the large cylinder 33 is driven by an external gear ring 14 via a belt 2. Specifically, the small cylinders 31 and 32 are located above the large cylinder 33. All three cylinders (31, 32, and 33) are located within a receiving cavity 6 of a housing 4, and the outer diameters of the small cylinders 31 and 32 are smaller than the outer diameter of the large cylinder 33. At least one pulley 20 is provided, with the three pulleys 20 located on the outer rear end walls of the output shafts of the three inner cylinders 3. The three pulleys 20 are connected to corresponding positions in a planetary gearbox 1 via belts 2. The three pulleys 20 are designated as a small drum pulley 21, a small drum pulley 22, and a large drum pulley 23. All three pulleys are located on the rear side of the housing 4, and are rotatably fitted against the rear outer wall of the output shaft of their respective inner drum 3. In this embodiment, the dimensions of the three inner drums 3 are set as required.

[0038] By using the three inner cylinders 3 and pulleys 20 in combination, the demand on the motor can be effectively reduced. The movement of the corresponding inner cylinder 3 is driven by the belt 2, achieving single-stage speed reduction. This improves the performance of the transmission device and reduces its cost. Furthermore, it enhances the flexibility of the transmission device layout. The elasticity of the belt 2 absorbs the significant impacts generated during motor start-up, stopping, and speed changes, providing a "soft buffer" for the rear planetary gearbox 1. This greatly reduces the instantaneous impact force during gear meshing, helping to extend the gearbox's lifespan.

[0039] The equipment housing 4 is integrally die-cast to form multiple receiving cavities 6. These cavities 6 serve to reduce vibration and noise, and also reduce the overall weight of the equipment, thus lowering manufacturing costs. Each receiving cavity 6 includes multiple cylindrical receiving cavities 60, each housing three inner cylinders 3, which are driven by a transmission device. Connecting parts 5 exist between the different receiving cavities 6, and a planetary gearbox 1 is located at the rear of the housing 4. The rear end of the receiving cavity 6 where the large cylinder 33 is located is a circular back plate, on which the planetary gearbox 1 is located. The front of the planetary gearbox 1 is on the same horizontal plane as the different receiving cavities 6, meaning the front of the planetary gearbox 1 is positioned at the rear of the receiving cavities 6. Each receiving cavity 6 includes a motor mounting cavity 61, located between the receiving cavities 6 housing the inner cylinders 3. The motor is mounted in the motor mounting cavity 61, and its output shaft is connected to the sun gear 11 in the planetary gearbox 1.

[0040] Unlike traditional methods where the inner cylinder 3 is suspended from the housing 4 via springs and dampers, which can lead to significant vibration and noise during operation and cause wear and tear on the springs due to prolonged use, this application integrally die-casts the cylinder housing cavity 60 with the housing 4. This creates a rigid whole between the cylinder and housing 4, while the damping housing cavity 6 helps neutralize the excitation frequency. Even if vibration occurs during operation, the presence of at least one housing cavity 6 effectively reduces vibration and noise, and also decreases damping between components. Furthermore, it eliminates the need for springs and dampers, significantly reducing equipment costs and extending its lifespan. This also improves the stability and reliability of the connection between the housing 4 and the inner cylinder 3.

[0041] Furthermore, a garment processing device includes a transmission mechanism. The connecting component 5 in the device comprises a cylinder-box connecting component 51 and an inter-cylinder connecting component 52. The cylinder-box connecting component 51 is located between the cylinder receiving cavity 60 and the box body 4, and is smoothly connected to both the cylinder receiving cavity 60 and the box body 4. This provides stable connection between the inner cylinder 3 and the box body 4, serving as support and providing shock absorption and noise reduction. The inter-cylinder connecting component 52 is located between the outer walls of any two cylinder receiving cavities 60, and is smoothly arc-connected to the connected cylinder receiving cavities 60; this enhances the strength and structural stability of the cylinder receiving cavity 60 and the box body 4 after integral die-casting. There are p cylinder-box connecting components 51, where p is a positive integer. p ≥ m; there are q inter-cylinder connecting components 52, where q is a positive integer. q ≥ 1. In this embodiment, the specific values ​​of p and q are set according to requirements. Additionally, the outer wall of the cylinder-box connecting component 51 consists of three arc edges and one straight edge. The outer wall of the inter-cylinder connector 52 is composed of four arc edges.

[0042] The arrangement of the cylinder-box connector 51 and the inter-cylinder connector 52 in the device can effectively improve the stability of the connection between the cylinder receiving cavity 60 and the box body 4, and between any two cylinder receiving cavities 60. It also helps to play a role in shock absorption by setting the arc edge of the outer wall of the cylinder-box connector 51 and the inter-cylinder connector 52, and can also enhance the rigidity of the cylinder-box connector 51 and the inter-cylinder connector 52.

[0043] Driving principle:

[0044] Driven by the motor, the planetary gearbox 1 receives different inputs and outputs depending on the instructions issued by the main controller in the garment processing equipment, thereby controlling the movement and frequency of the different inner drums 3. In this embodiment, the drive configuration has various variations, mainly depending on the selection of the input and output methods of the planetary gearbox 1.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
