[0025] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them.

[0027] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0028] like Figure 1-Figure 5As shown, the present embodiment provides a drum guide structure, comprising: a drum 1, a support frame 2 and a power assembly 4, wherein a storage cavity for placing clothes is formed inside the drum 1, the drum 1 comprises a first end and a second end opposite to each other, the first end being provided with a rotating portion; the support frame 2 comprises a base 201, a front supporting portion 202 and a rear supporting portion 203, the front supporting portion 202 and the rear supporting portion 203 are both mounted on the base 201, and a mounting position for rotatably mounting the drum 1 is formed between the front supporting portion 202 and the rear supporting portion 203, a ring groove 2031 rotatably matched with the second end is provided on a side of the rear supporting portion 203 opposite to the drum 1, a rotating member 3 is provided on a side of the front supporting portion 202 opposite to the first end, and the rotating member 3 is rollingly connected to the outer peripheral surface of the rotating portion; the power assembly 4 is mounted on the base 201, and the power end of the power assembly 4 is connected to the drum 1 for driving the drum 1 to rotate.
[0029] Based on the above scheme, there is a storage cavity inside the drum 1 for placing clothes to be dried. The two ends of the drum 1 are respectively a first end and a second end, wherein the first end has a protruding rotating portion; the support frame 2 includes a base 201, a front supporting portion 202 and a rear supporting portion 203, both of which are mounted on the base 201, and a mounting position is formed between them, and the drum 1 can be mounted at this position and rotated, and an annular groove 2031 is provided on the side of the rear supporting portion 203 close to the drum 1, and this groove is rotatably matched with the second end of the drum 1 to ensure that the drum 1 is rotated. The drum 1 can rotate stably on the rear support part 203. A rotating member 3 is provided on the side of the front support part 202 close to the first end of the drum 1. The rotating member 3 is rollingly connected to the outer peripheral surface of the rotating part of the first end of the drum 1. The rotating member 3 can be a structure such as a ball or a roller. The contact method between the rotating part and the rotating part is rolling rather than sliding, which can reduce the friction and make the rotation of the drum 1 smoother. The power component 4 is installed on the base 201, and its power end is connected to the drum 1. When the power component 4 is started, it drives the drum 1 to rotate, thereby driving the clothes to tumble inside the drum 1 to achieve the drying effect. The rolling connection between the rotating member 3 and the rotating part reduces the friction of the drum 1 during rotation, reduces the resistance caused by friction, makes the rotation of the drum 1 smoother, and improves the overall stability of the dryer. In traditional dryers, the rotation of the drum 1 often depends on the sliding cooperation with the support frame 2. This method is prone to cause displacement deviation of the drum 1 due to production errors or long-term use. The guide structure of the drum 1 in the present application is connected with the rotating part by the rolling connection of the rotating member 3. Even if there is a production error, it can be automatically adjusted by rolling, thereby avoiding the occurrence of displacement deviation. In addition, since the friction and resistance of the drum 1 during rotation are reduced, the wear of the drum 1 and related components is reduced, thereby extending the service life of the dryer. At the same time, the stable rotation of the drum 1 ensures the uniformity of the clothes during the drying process, avoids the problems of poor drying effect and damage to clothes caused by uneven distribution of clothes, and improves the user experience.
[0030] Furthermore, the rotating member 3 includes a rotating shaft 301, a rolling wheel 302 and a nut 303. One end of the rotating shaft 301 is fixed to the front support part 202, and the other end passes through the rolling wheel 302 and is fixedly connected to the nut 303. The rolling wheel 302 can rotate around the axis of the rotating shaft 301, and the rolling wheel 302 abuts against the rotating part. One end of the rotating shaft 301 is fixed to the front support part 202, and the other end passes through the center hole of the rolling wheel 302 and is fixed by the nut 303. In this way, the rolling wheel 302 can rotate freely around the axis of the rotating shaft 301. When the drum 1 starts to rotate under the drive of the power assembly 4, the first end of the drum 1 with the rotating part contacts the outer peripheral surface of the rolling wheel 302 and rolls relatively. The rolling wheel 302 can smoothly rotate around the rotating shaft 301, reducing the friction between the rotating part and the rolling wheel 302. Due to the rolling contact between the rolling wheel 302 and the rotating part, the rotation of the drum 1 is guided and balanced. Even if the drum 1 is affected by uneven distribution of clothes or other external forces, the rolling wheel 302 can automatically adjust through its rolling motion to ensure the smooth rotation of the drum 1. Moreover, as the drum 1 rotates smoothly, the clothes roll inside the drum 1 and are fully in contact with the hot air inside the dryer, so that the clothes are evenly dried. Compared with the traditional sliding contact, the rolling contact between the rolling wheel 302 and the rotating part significantly reduces the friction, making the rotation of the drum 1 smoother and reducing energy consumption. The guiding effect of the rolling wheel 302 keeps the drum 1 stable during the rotation process, avoiding shaking or deviation caused by uneven distribution of clothes or other external forces, and improving the overall balance of the dryer.
[0031] Furthermore, at least two rotating members 3 are provided, and each rotating member 3 is arranged at intervals along the circumference of the front support portion 202. At least two rotating members 3 are respectively located at different positions of the front support portion 202, and they are in rolling contact with the rotating part of the drum 1 to form a double-point support structure. This structure can better constrain the rotation of the drum 1 and reduce its shaking and deviation during the rotation process, thereby enhancing the overall stability of the dryer and maintaining a stable rotation trajectory. Since at least two rotating members 3 are distributed at different circumferential positions of the drum 1, they can jointly bear the weight of the drum 1 and the torque during rotation. When the drum 1 is affected by uneven clothing distribution or other external forces, these rotating members 3 can automatically adjust their positions through the rolling movement of the rolling wheel 302, thereby maintaining the balance and stability of the drum 1. This balance helps to improve the drying effect and clothing protection performance.
[0032] Optionally, a positioning groove 2021 is provided on the front support portion 202 to cooperate with the rotating portion. The positioning groove 2021 is located on the front support portion 202, and its shape and size match the rotating portion of the drum 1. When the drum 1 is installed on the support frame 2, the rotating portion will be accurately embedded in the positioning groove 2021 to form a stable positioning connection. In addition to the rolling connection between the rotating member 3 and the rotating portion, the positioning groove 2021 provides an additional auxiliary positioning function for the drum 1, which ensures the stability and accuracy of the drum 1 during installation and rotation. It can also be understood that the rolling connection between the rotating member 3 and the rotating portion and the cooperative positioning of the positioning groove 2021 and the rotating portion together constitute a double guarantee for the rotation of the drum 1. The rolling connection provides the smoothness of the rotation of the drum 1, while the positioning groove 2021 ensures the stability and accuracy of the rotation of the drum 1.
[0033] Preferably, a stirring part is provided in the storage cavity. The stirring part is usually installed inside the drum 1. It is designed to actively or passively stir the clothes when the drum 1 rotates, and its function is to help the clothes to tumble and distribute better inside the drum 1, and avoid the clothes from piling up or entangled during the drying process. This can ensure that the clothes are in more complete contact with the hot air inside the dryer, thereby improving the drying efficiency, and also help to reduce the wrinkles generated by the clothes during the drying process. During the tumbling and dispersion process of the clothes, the indentations and wrinkles formed by being immobile for a long time can be reduced. The stirring part can be a component of various shapes and structures, such as raised ribs, spiral agitators, etc.
[0034] Specifically, the stirring part is wavy. The stirring part is designed to be wavy, which means that it has an undulating surface. This design enables the stirring part to more effectively contact the clothes and generate a driving force when the drum 1 rotates. As the drum 1 rotates, the wavy stirring part will continuously contact the clothes, generating thrust and friction. This force can push the clothes to roll and move inside the drum 1, thereby preventing the clothes from piling up or entangled during the drying process. By improving the drying efficiency and drying quality, the design of the wavy stirring part can enhance the user experience, and the user can complete the drying of clothes more quickly and conveniently to meet daily needs.
[0035] In some embodiments, a reinforcing rib 204 is provided between the front support portion 202 and the rear support portion 203. The addition of the reinforcing rib 204 significantly improves the connection strength between the front and rear support portions 203, making the entire support structure more solid and stable, which helps to ensure the stability and reliability of the drum 1 during rotation. The design of the reinforcing rib 204 can also reduce the risk of damage to the support structure and extend its service life by dispersing stress and optimizing vibration transmission, which is of great significance for improving the overall performance of the dryer and reducing costs. In addition, the design of the reinforcing rib 204 makes the dryer more stable and reliable during operation, reduces the interference of vibration or noise to the user, can enhance the user's experience, and increase the user's satisfaction with the product. At the same time, the addition of the reinforcing rib 204 makes the support structure have better bearing capacity and adaptability. Whether it is fully loaded or unloaded, the dryer can maintain stable performance and meet various usage requirements.
[0036] At the same time, at least two reinforcing ribs 204 are provided, and the two reinforcing ribs 204 are arranged symmetrically. The two reinforcing ribs 204 are symmetrically arranged between the front support portion 202 and the rear support portion 203, which means that they are mirror-symmetrical in structure. This arrangement can ensure that the support structure is evenly reinforced on both sides, thereby achieving better balance and stability. The symmetrically arranged reinforcing ribs 204 can more effectively resist external stress and load. Whether it is horizontal force or vertical force, the two symmetrical reinforcing ribs 204 can share it together, thereby reducing the force burden of a single reinforcing rib 204 and improving the stability of the entire support structure.
[0037] It is worth mentioning that the power assembly 4 includes a motor and a transmission member, the motor is connected to the transmission member, and the outer peripheral wall of the transmission member is in contact with the outer peripheral wall of the drum 1 to realize that the drum 1 rotates with the rotation of the transmission member. The motor is the core of the power assembly 4, which generates a rotational torque. When the motor is started, it will transfer the rotational torque to the transmission member through a transmission mechanism (such as gears, belts, etc.). The transmission member is a key component connecting the motor and the drum 1. After receiving the rotational torque of the motor, the transmission member starts to rotate. Since the outer peripheral wall of the transmission member is in contact with the outer peripheral wall of the drum 1, when the transmission member rotates, it will drive the drum 1 to rotate through friction. This contact mode ensures that the drum 1 can rotate synchronously with the rotation of the transmission member. This design does not require a complex transmission mechanism or intermediate components. The rotation of the drum 1 can be realized only by the contact between the motor, the transmission member and the drum 1, which not only reduces the manufacturing cost, but also improves the reliability of the system. At the same time, due to the simple structure, this design is also more convenient in maintenance. When repair or replacement of parts is required, it can be easily disassembled and assembled. At the same time, since the motor directly drives the transmission member, and the transmission member directly drives the drum 1 through friction, the transmission efficiency of this design is relatively high, which helps to reduce energy loss and improve the energy efficiency of the dryer.
