Detailed implementation manners

[0026] To make the technical problems solved by the present application, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present application will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0027] In the description of the present application, unless otherwise clearly defined and limited, the terms "connected", "connected", "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0028] In the present application, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below" and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature has a lower horizontal height than the second feature.

[0029] Such as Figures 1-5As shown in the figure, this embodiment provides a drainage structure for a dryer, including: a support frame 1, a drum 2, a water absorption member 3, a power shaft 4, an auxiliary shaft group 5, a water squeezing assembly 6, and a water receiving tray 7. The drum 2 is rotatably installed on the support frame 1. A plurality of drainage holes are provided on the outer wall surface of the drum 2. The power shaft 4 and the auxiliary shaft group 5 are circumferentially and spacedly arranged on the support frame 1 along the outer wall surface of the drum 2, and there is a gap between them and the outer wall surface of the drum 2. The water absorption member 3 is in an annular structure and is wound around the power shaft 4 and the auxiliary shaft group 5. The area of the water absorption member 3 covers the drainage holes;

[0030] The water squeezing assembly 6 is installed on the support frame 1 and protrudes along the length direction of the drum 2. The water squeezing assembly 6 includes a fixed part 601 on one side of the water absorption member 3, a squeezing part 602 movably arranged on the opposite side of the water absorption member 3, and a driving part capable of driving the squeezing part 602 to move relative to the fixed part 601 or move away from the fixed part 601. The water receiving tray 7 is located below the squeezing part 602;

[0031] The drainage structure is configured as follows: the power shaft 4 drives the water absorption member 3 to rotate cyclically around the auxiliary shaft group 5, the driving part drives the squeezing part 602 to move relatively, the squeezing part 602 squeezes the water absorption member 3, and the water adsorbed by the water absorption member 3 is squeezed and dripped onto the water receiving tray 7.

[0032] Based on the above scheme, the multiple drainage holes carefully arranged on the outer wall of the drum 2 are first utilized. The design of these drainage holes cleverly avoids the common path of the clothes when they rotate in the drum 2, effectively reducing the direct obstruction of the clothes to the drainage process, so that the spun water can flow out more smoothly. Next, the annular water absorbent 3 is introduced. The water absorbent 3 is tightly and flexibly wound around the power shaft 4 and the auxiliary shaft group 5. Its surface area is carefully designed to completely cover all the drainage holes on the outer wall of the drum 2. This design ensures that every drop of water flowing out of the drainage hole can be quickly and effectively absorbed by the water absorbent 3, avoiding the direct dripping or accumulation of water around the drum 2, and further improving the drainage efficiency. In order to achieve rapid discharge of the water collected in the water absorbent 3, the system is also equipped with an efficient water squeezing component 6, which consists of a fixed part 601, a movable squeezing part 602 and a driving part, which work together to complete the squeezing process. When the water absorbent 3 collects a certain amount of water, the driving part will start and drive the squeezing part 602 to move relative to the fixed part 601, and strongly squeeze the water absorbent 3. This squeezing action forces the water absorbed in the water absorbent 3 to be quickly discharged, forming continuous water droplets that directly drip into the water receiving tray 7 below. The water receiving tray 7 is the final collection point of the entire drainage structure, and its design also embodies humanization and practicality. The water receiving tray 7 is located directly below the squeezing part 602, and can accurately and efficiently receive the water droplets squeezed out of the water absorbent 3. At the same time, the water receiving tray 7 can also discharge the collected water to the outside of the dryer in time, avoiding the accumulation of water in the machine and the possible generation of odor. To sum up, the drainage structure of the dryer described in the present application realizes the rapid collection, effective squeezing and smooth discharge of water from clothes through the perfect combination of the drainage holes on the outer wall of the drum 2, the surrounding water absorbent 3, the high-efficiency water squeezing component 6 and the humanized water receiving tray 7. This innovative design not only significantly improves the drainage efficiency and user experience of the dryer, but also reduces energy consumption and noise levels, bringing users a more convenient, comfortable and environmentally friendly drying experience.

[0033] Further, the auxiliary shaft group 5 includes a plurality of driven shafts 501, and the plurality of driven shafts 501 are circumferentially and spacedly arranged on the support frame 1 along the outer wall surface of the drum 2. In this solution, the auxiliary shaft group 5 is no longer limited to a single shaft body, but cleverly adopts a layout where a plurality of driven shafts 501 are circumferentially and spacedly arranged on the support frame 1 along the outer wall surface of the drum 2. This design not only enhances the overall stability of the drainage system, enabling the water-absorbing member 3 to work more smoothly when rotating around the drum 2, reducing jitter or deviation caused by uneven force; at the same time, the support of the plurality of driven shafts 501 also optimizes the water absorption efficiency, ensuring that the water-absorbing member 3 can closely adhere to the surface of the drum 2 and collect every drop of water flowing out from the drain holes without omission. In addition, this multi-shaft layout also improves the adaptability of the drainage system to different clothing loads, and can maintain an efficient and stable drainage effect regardless of the amount of clothing. More importantly, the multi-shaft design also provides great convenience for subsequent maintenance and replacement work. Users or maintenance personnel can easily access each driven shaft 501 for necessary operations, ensuring the long-term stable operation of the drainage system.

[0034] In addition, it further includes a power member, and the power end of the power member is connected to the power shaft 4 for driving the power shaft 4 to rotate. The power member serves as the power source of the entire drainage system, and its power end is closely connected to the power shaft 4. By transmitting mechanical energy or electrical energy, it drives the power shaft 4 to rotate. The rotation of the power shaft 4 then drives the water-absorbing member 3 to rotate cyclically around the auxiliary shaft group 5 (i.e., a plurality of driven shafts 501), forming a continuous water absorption - water squeezing cycle. This design not only simplifies the drainage process, reduces the need for manual intervention, but also improves the drainage efficiency, ensuring that the dryer can continuously and stably drain the moisture in the clothes during the drying process. In addition, the introduction of the power member also makes the control of the drainage system more precise and flexible. By adjusting the output power or rotation speed of the power member, precise control of the rotation speed of the water-absorbing member 3 can be achieved, so as to adapt to the different drainage efficiency requirements of different materials and weights of clothes. This intelligent and personalized design will undoubtedly bring a more convenient and efficient user experience to users.

[0035] In particular, a plurality of hook portions are convexly provided on the outer peripheral wall of the power shaft 4, and these hook portions are ingeniously designed to be able to frictionally abut against the inner wall of the water absorption member 3. This design enables the power shaft 4 to not only transmit power through the traditional connection method between the shaft and the shaft sleeve when rotating, but also directly drive the water absorption member 3 to rotate cyclically around a plurality of driven shafts 501 through the frictional force between the hook portions and the inner wall of the water absorption member 3. This dual-drive mechanism brings multiple advantages. Firstly, the close contact between the hook portions and the inner wall of the water absorption member 3 ensures the stability and reliability of power transmission, avoiding power loss caused by loosening or wear of transmission components. Secondly, the friction-driven method makes the water absorption member 3 rotate more smoothly during the rotation process, reducing vibrations and noises caused by sudden acceleration or deceleration. In addition, the design of the hook portions also enhances the connection strength between the water absorption member 3 and the power shaft 4, enabling the entire drainage system to still maintain the structural integrity and stability during high-speed operation.

[0036] At the same time, this design also takes into account the replacement and maintenance of the water absorption member 3. Since the contact between the hook portions and the inner wall of the water absorption member 3 is frictional, it will not cause permanent damage to the water absorption member 3. When it is necessary to replace or clean the water absorption member 3, the user can easily remove it from the power shaft 4 without worrying about damaging any components.

[0037] In some embodiments, the water squeezing assembly 6 further includes a support portion 604, the support portion 604 is convexly provided on the support frame 1 along the length direction of the roller 2, and the driving portion is mounted on the support portion 604. The support portion 604 is convexly provided on the support frame 1 along the length direction of the roller 2, providing a stable installation foundation for the entire water squeezing assembly 6. This design makes the water squeezing assembly 6 more stable during installation, not easy to shake or displace, thus ensuring that the water absorption member 3 can be continuously and stably squeezed during the water squeezing process, improving the drainage efficiency. At the same time, the driving portion is mounted on the support portion 604. As the power source of the water squeezing assembly 6, the stability and reliability of the driving portion are crucial for the performance of the entire drainage system. By mounting the driving portion on the support portion 604, the risk of loosening or damage of the driving portion caused by vibration or impact can be effectively reduced, ensuring that the driving portion can work stably for a long time. Moreover, the design of the support portion 604 also takes into account the convenience of maintenance. Since the support portion 604 is convexly provided on the support frame 1, it provides sufficient operating space for maintenance personnel, enabling them to more conveniently access and check each component of the water squeezing assembly 6, including the driving portion, the squeezing portion 602, and the fixing portion 601, etc. This design not only improves the maintenance efficiency but also reduces the maintenance cost.

[0038] More specifically, the water squeezing assembly 6 further includes a first strengthening portion 605, and the first strengthening portion 605 is obliquely connected to the bottom of the supporting portion 604 and the side surface of the supporting frame 1. The main function of the first strengthening portion 605 is to enhance the connection strength between the supporting portion 604 and the supporting frame 1, thereby further improving the overall stability of the water squeezing assembly 6. Since the water squeezing assembly 6 needs to bear the squeezing force from the water absorbing member 3 and its own running force during the working process, it is necessary to ensure that its connection with the supporting frame 1 is firm enough to avoid failures caused by loosening or breaking. The first strengthening portion 605 is obliquely connected, which can not only effectively disperse the stress and vibration generated by the water squeezing assembly 6 during the working process, but also enhance the stability and durability of the connection. This design enables the water squeezing assembly 6 to maintain the integrity and stability of the structure when running at high speed or being impacted by external forces, ensuring the normal operation of the drainage system. In addition, the setting of the first strengthening portion 605 also takes into account the overall aesthetics of the drainage structure. Through fine design and processing, the first strengthening portion 605 can be seamlessly connected with the supporting portion 604 and the supporting frame 1 to form an appearance with a strong overall sense and smooth lines, enhancing the overall texture of the product.

[0039] Furthermore, a second strengthening portion 701 is provided at the bottom of the water receiving tray 7, and the second strengthening portion 701 is obliquely connected to the bottom of the water receiving tray 7 and the side surface of the supporting frame 1. The second strengthening portion 701 is obliquely connected to the bottom of the water receiving tray 7 and the side surface of the supporting frame 1. This design not only increases the contact area between the water receiving tray 7 and the supporting frame 1, but also effectively disperses the stress and vibration that may be generated by the water receiving tray 7 when carrying water through the inclined angle. This way of dispersing stress enables the water receiving tray 7 to maintain the structural stability and durability when carrying a large amount of water for a long time.

[0040] Even further, a water storage cavity is formed in the water receiving tray 7, and a drainage channel is formed by hollowing out the inside of the second strengthening portion 701, and the drainage channel is communicated with the water storage cavity. The drainage channel and the water storage cavity are in communication, that is, the water accumulated in the water storage cavity can be smoothly discharged through the drainage channel. This design not only improves the drainage efficiency, but also avoids the long-term accumulation of water in the water receiving tray 7, thereby reducing the risk of bacterial growth and ensuring the hygiene of the drainage system. At the same time, the hollow design inside the second strengthening portion 701 does not sacrifice its strengthening effect. On the contrary, through reasonable structural design, the drainage channel is combined with the reinforcing rib, which not only ensures the firm connection between the water receiving tray 7 and the supporting frame 1, but also realizes the rapid discharge of water. In addition, from the perspective of user experience, this design also brings convenience. Users do not need to empty the water receiving tray 7 frequently because the drainage channel can automatically discharge the accumulated water, reducing the maintenance workload of users. At the same time, since the hygiene of the drainage system is improved, the user experience will be more comfortable and reassuring.

[0041] Meanwhile, it also includes a drain pipe. The water inlet end of the drain pipe is communicated with the drainage channel, and the water outlet end of the drain pipe is connected to the outside of the dryer. The water inlet end of the drain pipe is communicated with the drainage channel. In this way, when a certain amount of water accumulates in the water storage cavity, this water can smoothly flow into the drain pipe through the drainage channel. The water outlet end of the drain pipe is connected to the outside of the dryer to ensure that the water can be discharged to the outside of the machine, avoiding unnecessary damage or affecting the use effect caused by accumulation inside the machine. The setting of the drain pipe not only improves the overall efficiency of the drainage system, but also ensures the dryness and cleanliness inside the dryer. By discharging the water in time, it can effectively reduce the growth of bacteria and other microorganisms and improve the sanitation level of the use environment. At the same time, this also reduces the maintenance burden on users and eliminates the need to frequently manually clean the water receiving tray 7 or the drainage system.

[0042] It is worth mentioning that in the design of the drainage structure of the dryer, the material selection of the water absorption member 3 is equally crucial. In particular, the water absorption member 3 made of rubber material has many advantages, making it an ideal choice in this structure. First of all, the rubber material has good water absorption and water retention properties, which means that the water absorption member 3 can quickly absorb and retain the water discharged from the clothes, ensuring the continuity and efficiency of the drainage process. At the same time, the elasticity of the rubber material also enables it to better fit the surface of the drum 2, reducing water leakage and overflow. Secondly, the rubber material has good wear resistance and corrosion resistance. During the use of the dryer, the water absorption member 3 needs to continuously contact and rub with the power shaft 4 and the driven shaft 501, and at the same time, it also has to withstand the erosion of water. Therefore, choosing a wear-resistant and corrosion-resistant material is crucial for extending the service life of the water absorption member 3. The rubber material just has these characteristics, enabling the water absorption member 3 to maintain stable performance in a harsh working environment. In addition, the rubber material also has good processability and cost-effectiveness. The rubber material can be cut, formed and other processing treatments according to actual needs to meet the drainage structure requirements of different models and specifications of dryers. At the same time, compared with other materials, the cost of the rubber material is relatively low, which helps to reduce the manufacturing cost and selling price of the product.
