Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a transmission mechanism for an independent clothes dryer. Background Technology

[0002] As a convenient and efficient household appliance, the market demand for clothes dryers continues to expand. The drive motor, as the core power component of a clothes dryer, directly affects the reliability, noise level, and cost of the entire machine.

[0003] Currently, most dryers on the market use drive motors whose transmission-related functional structures (such as the support shaft of the reduction gear, the hanging spring holes for suspension and shock absorption, and the shock-absorbing support structure connecting the housing) are typically designed and molded directly onto the motor's own casing. This integrated design has significant drawbacks: to adapt to the internal space layout and installation requirements of different brands and models of dryers, motor manufacturers must design and manufacture motor casings of different shapes and mounting point positions for each model. This results in complex motor casing structures, extremely poor versatility, high mold costs, and cumbersome production management, ultimately increasing the overall cost of the machine and hindering the standardization of parts and rapid repair and replacement. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems and provide a transmission mechanism for an independent clothes dryer.

[0005] To achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by this utility model is: an independent clothes dryer transmission mechanism, including a transmission bracket independently of the motor housing, wherein the transmission bracket is an independent structure and is provided with: A reduction gear mounting section is used to rotatably support the reduction gear; The spring connecting part is used to connect the suspension spring; The body connection section is used to install the transmission bracket to the dryer body via the shock absorption assembly.

[0006] Preferably, the body connection includes at least one shock-absorbing support column protruding outward from the transmission bracket, and / or a shock-absorbing support plane formed on the transmission bracket.

[0007] Preferably, the transmission bracket has a bearing mounting hole, and the outer periphery of the sliding bearing is tightly fitted and fixed with the bearing mounting hole.

[0008] Preferably, the inner hole of the sliding bearing is used to fit and rotate relative to the stator support shaft of the outer rotor motor to adjust the tension of the suspension spring connected to the spring connection.

[0009] Preferably, the reduction wheel mounting part includes a reduction wheel support shaft integrally formed with the transmission bracket.

[0010] Compared with the traditional structure, the beneficial effects of this utility model are: 1. This utility model integrates the three major functions of reduction wheel support, spring suspension and machine body installation into one by designing an independent transmission bracket, which greatly simplifies the motor body and makes it a standardized component that can be used in a variety of dryer platforms, significantly improving the versatility and interchangeability of parts.

[0011] 2. As an independent functional module, the transmission bracket facilitates pre-assembly, debugging, and individual installation on the assembly line. During maintenance, the transmission bracket or motor can be replaced independently without interference, greatly improving the efficiency of production and after-sales maintenance.

[0012] 3. Through the relative rotation design of the sliding bearing and the motor stator shaft, the transmission bracket can undergo a small angular displacement around the stator shaft, thereby dynamically adjusting the tension of the suspension spring, achieving a better adaptive damping effect, and improving the overall stability of the machine operation.

[0014] The present invention will be further described below.

[0015] See attached document Figure 1-2 A transmission mechanism for a stand-alone clothes dryer includes a transmission bracket 1 that is independent of the motor housing. The transmission bracket 1 is an independent structure on which the following are mounted: The reduction wheel mounting part 2 and the transmission bracket 1 are integrally formed with a cylindrical reduction wheel support shaft 22. The reduction wheel 21 is mounted on this shaft through a bearing to achieve rotatable support. The hanging spring connection part 3 is located on the transmission bracket 1 and is used to connect the suspension spring. In this embodiment, it is specifically a circular hanging spring hole 31, in which one end of the suspension spring of the dryer is hooked. The body connecting part 4, located on the transmission bracket 1, is used to connect to the dryer housing. In this embodiment, the body connecting part 4 includes two upwardly protruding cylindrical shock-absorbing support columns 41 and a flat shock-absorbing support plane 42. During installation, this part is fixedly connected to the dryer housing by shock-absorbing components 43 and fasteners.

[0016] Bearing mounting structure: Bearing mounting holes 5 are precision-machined on the body of the transmission bracket 1. The sliding bearing is press-fitted into these holes with its outer circumference. The stator support shaft of the external rotor motor passes through the inner hole of the sliding bearing. A precise clearance fit exists between the inner hole of the sliding bearing and the stator support shaft, allowing relative rotation between them. This design allows the entire transmission bracket 1 to have a slight degree of freedom of oscillation around the stator support shaft, thereby automatically adjusting the effective length and tension of the suspension spring hanging on the spring mounting hole 31 according to load changes, achieving optimized vibration damping.

[0017] In practice, a standard universal motor is connected via its stator support shaft inserted into the sliding bearing of the transmission bracket 1. The transmission bracket 1 is then mounted to the dryer's housing via its body connection part 4 (shock-absorbing support column, flat surface). The reduction wheel 21 is mounted on the reduction wheel support shaft 22 and connected to the motor's output end via a belt or gear. One end of the suspension spring is connected to the spring hanging hole 31, and the other end suspends the roller. Thus, a complete, efficient, and modular dryer drive transmission system is constructed.

[0018] It should be noted that the shape of the transmission bracket, the specific form of each functional part, and their relative positions are only one preferred embodiment. The scope of protection of this utility model is not limited thereto. For example, the transmission bracket can also be injection molded from high-strength engineering plastic; the shock-absorbing support structure can be entirely support columns or entirely support surfaces; the hanging spring connection part can be a hook, a slot, or other forms. Any technical solution that uses a bracket independent of the motor housing as a base, and integrates on this base a mounting part for supporting the reduction wheel, a connection part for connecting the suspension spring, and a connection part for connecting the dryer body, falls within the scope of protection of the claims of this utility model.

[0019] The above embodiments of this utility model are merely examples to clearly illustrate this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent technical solutions also fall within the scope of this utility model, and the patent protection scope of this utility model should be defined by each claim.
