Description

Technical Field

[0001] This utility model relates to the field of clothes dryer technology, and more specifically, to a clothes dryer. Background Technology

[0002] In the existing technology, clothes dryers are important equipment in the home and commercial laundry fields. Their performance is directly related to the drying effect of clothes, energy consumption and user experience. However, the clothes dryers currently on the market still have some shortcomings in terms of structural design and functional implementation.

[0003] Firstly, most existing dryers use a simple stacking drying method, where clothes are directly stacked inside the drying chamber for hot air circulation. While this design is simple and easy to operate, it has significant technical drawbacks: First, the stacking of clothes creates heat transfer barriers at the contact surfaces, making it difficult for hot air to penetrate evenly to every corner of the clothes. This is especially true for thick fabrics or multi-layered garments, where the interior often becomes damp due to insufficient hot air contact. Second, the stacking structure results in a significantly smaller hot air contact area for clothes at the bottom or center compared to the outer layers, causing significant differences in dryness between different areas. Furthermore, stacking clothes reduces the overall airflow efficiency within the drying chamber, prolonging the residence time of hot air between clothes, but reducing heat utilization and leading to additional energy consumption. This method of directly stacking clothes for drying not only results in incomplete drying, requiring users to manually turn the clothes to ensure even drying, but also significantly reduces overall drying efficiency, prolongs the drying cycle, and increases energy consumption.

[0004] Secondly, existing dryers have significant shortcomings in their hot air system design. Most dryers use a fixed airflow and heat output design, lacking an effective wind speed adjustment mechanism. The limitations of this design are mainly reflected in the following aspects: First, it cannot adjust the hot air delivery speed according to the characteristics of different fabrics. For example, cotton clothes are suitable for deep penetration drying with lower wind speeds, while synthetic fabrics are suitable for rapid surface drying with higher wind speeds. The fixed wind speed design prevents different fabrics from achieving optimal drying results. Second, in different usage scenarios (such as rapid drying or gentle care), the equipment cannot adjust the hot air delivery intensity according to actual needs, limiting the user's flexibility. Third, seasonal climate changes and indoor humidity differences have a significant impact on the drying process, and the fixed wind speed system cannot make environmental adaptation adjustments, resulting in decreased drying efficiency in high humidity environments. This design flaw, which cannot flexibly adjust the hot air delivery speed according to the fabric and actual usage needs, not only affects the drying quality and efficiency of clothes but also increases the risk of damage to special fabrics, failing to meet the diverse functional needs of modern families for dryers.

[0005] Furthermore, some improved clothes dryers on the market have attempted to address the aforementioned issues by adding fan speed adjustment devices. However, while these improved devices achieve flexible adjustment of the hot air delivery speed through the cooperation of certain components, their simple and crude structural design results in low overall stability, and they still face many technical challenges in practical use. The main problems are as follows: First, these adjustment mechanisms lack precise locking and anti-loosening designs, making it difficult for the adjusted components to maintain long-term stability; second, during the operation of the clothes dryer, there are significant pressure fluctuations inside the hot air duct, especially when the fan starts and stops, and the instantaneous pressure changes can cause continuous impact on the adjustment components. Impacts gradually cause slight displacement of the adjusted components; in addition, external factors such as long-term operation of the equipment and accidental contact by the user can also cause displacement of the adjusted flow rate control components. This lack of structural stability directly affects the performance: the adjusted hot air flow rate often undergoes unpredictable changes during actual operation, resulting in unstable drying temperature and intensity, increased energy consumption, and prolonged drying time. This adversely affects the protection of clothing and the service life of the equipment, and fails to meet the basic needs of modern families for high-quality, high-efficiency, and highly stable clothes drying equipment.

[0010] The present invention is further provided that a support frame is provided inside the drying chamber, a clothes hanger is detachably installed on the support frame, and a caster wheel is detachably installed at the bottom of the support frame.

[0011] The present invention is further configured such that an exhaust pipe is connected to the top of the side wall of the drying chamber, a fan and a heating chamber are detachably provided on the back side of the drying chamber, the input end of the heating chamber is connected to the output end of the fan, and the output end of the heating chamber is connected to one end of the conveying pipe.

[0012] The present invention is further provided that a filter plate is detachably installed at the input end of the fan, and the filter plate effectively prevents foreign objects from entering the pipeline system.

[0013] The present invention is further configured such that an adapter rod is fixedly connected to one side of the adapter block, and an adapter hole is provided in the fixed block. One end of the adapter rod slides into the adapter hole. The configuration of the adapter rod and the adapter groove ensures the stable use of the adapter spring.

[0014] The present invention is further configured such that a sliding block is fixedly provided on the inner side of the slot sleeve, and a sliding groove is provided on the outer side of the air intake pipe. The sliding block slides in the sliding groove, and the sliding block and the sliding groove realize the guiding and limiting function of the slot sleeve.

[0015] The present invention is further configured such that a movable spring is movably sleeved on the outer side of the movable rod, one end of the movable spring is connected to the locking sleeve, and the other end of the movable spring abuts against one side of the movable plate. The movable spring enables the locking sleeve to automatically reset.

[0016] The present invention is further configured such that a guide groove is provided on the outer side of the displacement rod, and a guide rail is fixedly provided on the inner wall of the connecting sleeve. The guide groove and the guide rail are adapted to each other, and the arrangement of the guide groove and the guide rail ensures the stable axial displacement of the displacement rod.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a clothes dryer with the following advantages:

[0019] 1. By incorporating a support frame within the drying chamber and a double-layered design with hanging racks, the system effectively solves the problem of incomplete drying caused by directly stacking clothes in existing technologies. This design allows clothes to be neatly arranged and hung on the racks, completely avoiding stacking and eliminating heat transfer barriers. This ensures that hot air can evenly penetrate every corner of the clothes. The double-layered racks increase the contact area between the clothes and the hot air, ensuring that all clothes receive uniform hot air contact and effectively preventing the "wet core" phenomenon. Furthermore, the casters at the bottom of the support frame allow the entire system to be easily removed from the drying chamber, facilitating the arrangement and placement of clothes without the need for frequent manual turning to ensure even drying. In addition, the bottom-up hot air flow design, combined with the hanging clothes arrangement, significantly improves the air circulation efficiency within the drying chamber, increases heat utilization, reduces additional energy consumption, greatly enhances overall drying efficiency, and shortens the drying cycle.

[0020] 2. Through the ingenious coordination of components such as the adjusting sleeve, screw sleeve, screw, shifting rod, connecting sleeve, and flow grooves on the side wall of the connecting sleeve, a hot air flow rate adjustment system is constructed. This effectively overcomes the shortcomings of existing dryers that cannot adjust the hot air delivery speed according to the material of the clothing and actual usage needs. The system rotates the adjusting sleeve, causing the screw sleeve to rotate. Utilizing the threaded transmission principle, the screw drives the shifting rod to make precise axial movement, thereby changing the number of flow grooves on the side wall of the connecting sleeve blocked by the shifting rod. This achieves control over the flow area within the air inlet pipe. This design allows users to adjust the hot air delivery speed according to the characteristics of different clothing materials. The system allows for targeted adjustments to the airflow speed. For example, a lower airflow speed can be selected for deep penetration drying of cotton clothing, while a higher airflow speed can be selected for rapid surface drying of synthetic fiber clothing. This ensures that different types of clothing can achieve optimal drying results. At the same time, the system also allows users to flexibly adjust the hot air delivery intensity according to different usage scenarios (such as rapid drying or gentle care), seasonal climate changes, and differences in indoor humidity. This environmental adaptability greatly improves the flexibility of the equipment, reduces the risk of damage to special fabrics, and fully meets the diverse functional needs of modern families for dryers.

[0021] 3. Employing a multi-locking structure design, a highly reliable multi-locking protection mechanism is constructed through the precise cooperation of components such as the locking sleeve, locking frame, locking rod, locking plate, connecting spring, locking groove, movable rod, movable spring, adapter block, adapter rod, adapter spring, fixing block, and moving plate. This completely solves the problem of insufficient stability in existing improved dryer adjustment mechanisms. Firstly, the design achieves initial fixation of the adjustment sleeve through the insertion locking method of the locking rod and locking groove. Secondly, the limiting effect of the inner wall of the locking sleeve on the outer wall of the locking plate prevents the locking rod from accidentally sliding out of the locking groove. Thirdly, the staggered design of the movable rod, moving plate, and moving hole ensures that the movable rod will not accidentally enter the moving plate. The locking mechanism is unlocked by the hole; finally, the cooperation between the sliding block and the sliding groove further restricts the movement freedom of the locking sleeve. This multi-locking structure can effectively resist the influence of external factors such as pressure fluctuations inside the hot air duct during the operation of the dryer, instantaneous pressure changes when the fan starts and stops, vibrations during long-term operation, and accidental contact by the user on the adjusting components. This ensures that the adjusted components will not have slight displacement, and that the adjusted hot air flow rate remains stable during actual operation. This, in turn, ensures the stability of the drying temperature and intensity, improves the protection of clothing and the service life of the equipment, and fully meets the basic needs of modern families for high-quality, high-efficiency, and high-stability drying equipment.

[0031] Please see Figures 1-5A clothes dryer includes a drying chamber 1, a door 2 rotatably connected to one side of the drying chamber 1, an air inlet pipe 3 connected to the bottom of the side wall of the drying chamber 1, an adjusting sleeve 4 above the air inlet pipe 3, a conveying pipe 5 rotatably connected to the other end of the adjusting sleeve 4, and the adjusting sleeve 4 and the air inlet pipe 3 are rotatably connected, a locking sleeve 6 is slidably fitted on the outside of the air inlet pipe 3, a movable plate 7 is rotatably mounted on the outside of the air inlet pipe 3, an adapter block 8 is fixedly connected to one side of the movable plate 7, a fixing block 9 is fixedly mounted on the outside of the air inlet pipe 3, an adapter spring 10 is movably mounted on the outside of the air inlet pipe 3, the two ends of the adapter spring 10 are respectively connected to the adapter block 8 and the fixing block 9, a locking frame 11 is fixedly mounted on one side of the adjusting sleeve 4, a locking rod 12 is slidably mounted in the locking frame 11, and a locking rod 12 is slidably mounted on the outside of the locking rod 12. A connecting spring 13 is provided in the movable sleeve. One end of the locking rod 12 is fixedly connected to the locking plate 14. The two ends of the connecting spring 13 are respectively connected to the locking plate 14 and the locking frame 11. A screw sleeve 15 is fixedly provided inside the adjusting sleeve 4. Multiple locking grooves 16 are opened on the outside of the air intake pipe 3. One end of the locking rod 12 is inserted into the locking groove 16. A moving hole 17 is opened on the moving plate 7. A movable rod 18 is fixedly connected to one side of the locking sleeve 6. A connecting plate 19 is fixedly connected to the inside of the air intake pipe 3. A connecting sleeve 20 is fixedly connected to the inside of the connecting plate 19. Multiple flow grooves 21 are opened on the side wall of the connecting sleeve 20. A shifting rod 22 is slidably provided in the connecting sleeve 20. A screw 23 is fixedly connected to one end of the shifting rod 22. The screw sleeve 15 and the screw 23 are movably connected by threads.

[0032] The drying chamber 1 is equipped with a support frame 24, on which a clothes hanger 25 is detachably installed, and at the bottom of the support frame 24, a caster wheel 26 is detachably installed.

[0033] An exhaust pipe 27 is connected to the top of the side wall of the drying chamber 1. A fan 28 and a heating chamber 29 are detachably provided on the back side of the drying chamber 1. The input end of the heating chamber 29 is connected to the output end of the fan 28, and the output end of the heating chamber 29 is connected to one end of the conveying pipe 5.

[0034] The input end of the fan 28 is detachably equipped with a filter plate 30.

[0035] In this embodiment, when the device is needed, the door 2 is opened using the handle on one side of the door 2, and then the locking mechanism on the caster wheel 26 is activated. The support frame 24 is then pushed outwards, causing the support frame 24 to move the clothes hanger 25 out of the drying chamber 1 via the bottom caster wheel 26. The clothes to be dried are then smoothed and hung on the clothes hanger 25, which has two layers to prevent clothes from piling up. The support frame 24 is then pushed back into the drying chamber 1, and the locking mechanism on the caster wheel 26 is closed, ensuring the support frame 24 remains stably in the drying chamber 1. The door 2 is then closed again, creating a relatively sealed space between the drying chamber 1 and the inside of the door 2. The door 2 is locked to one side of the drying chamber 1 using a common locking mechanism found in existing technologies. Then, the heating chamber 29 is heated by the built-in resistance wire. The fan 28 installed on the back side is then opened, drawing in outside air. The input end of the fan 28 is installed on the filter plate 30 to filter the drawn-in air and prevent foreign objects from entering. The air drawn in by the fan 28 is then delivered to the heating chamber 29 for heating, turning it into hot air. It is then delivered to the bottom of the drying chamber 1 through the conveying pipe 5 and the air inlet pipe 3, drying from bottom to top. The hot air dries the clothes on the clothes hanger 25, ensuring drying efficiency. The hot air carries the evaporated moisture through the exhaust pipe 27 and is discharged into the subsequent collection and treatment equipment, finally achieving gas emission.

[0036] Please see Figure 4 and Figure 5 As a further implementation of the overall device: an adapter rod 31 is fixedly connected to one side of the adapter block 8, and an adapter hole 32 is opened in the fixed block 9, with one end of the adapter rod 31 slidingly inserted into the adapter hole 32.

[0037] A sliding block 33 is fixedly provided on the inner side of the slot sleeve 6, and a sliding groove 34 is provided on the outer side of the air intake pipe 3, and the sliding block 33 slides in the sliding groove 34.

[0038] A movable spring 35 is movably sleeved on the outer side of the movable rod 18. One end of the movable spring 35 is connected to the locking sleeve 6, and the other end of the movable spring 35 abuts against one side of the movable plate 7.

[0039] The outer side of the shifting rod 22 is provided with a guide groove 36, and the inner wall of the connecting sleeve 20 is fixed with a guide rail 37. The guide groove 36 is adapted to the guide rail 37.

[0040] More specifically, when the hot air input speed needs to be adjusted according to the clothing material and actual usage, firstly, rotate the moving plate 7 in the forward direction. The moving plate 7 will drive the moving hole 17 and the adapter block 8 installed on one side to rotate in the forward direction. Then, the adapter block 8 will drive the adapter rod 31 on one side to slide along the adapter hole 32. The adapter block 8 will cooperate with the fixing block 9 to compress the adapter spring 10. When the adapter spring 10 is compressed to its limit, the moving hole 17 will rotate to a position concentric with the movable rod 18. Then, push the locking sleeve 6. The locking sleeve 6 will drive the inner sliding block 33 to slide along the sliding groove 34. The locking sleeve 6 will also drive the movable rod 18 on one side to slide into the moving hole 17, so that the inner wall of the locking sleeve 6 no longer limits the outer wall of the locking plate 14. Then, rotate the adjusting sleeve in the forward direction. 4. The adjusting sleeve 4 will drive the connecting spring 13, the locking rod 12, and the locking plate 14 to rotate forward through the locking bracket 11 on one side. At this time, the inner wall of the locking groove 16 will press against one end of the locking rod 12. Due to the rounded corner design of the inner wall edge of the locking groove 16 and one end of the locking rod 12, one end of the locking rod 12 will slide out of the locking groove 16, and the other end of the locking rod 12 will drive the connecting spring 13 to stretch outward through the locking plate 14. At the same time, the adjusting sleeve 4 will drive the inner threaded sleeve 15 to rotate forward. Since the threaded sleeve 15 is movably connected to the screw 23 through the thread, and the guide rail 37 and the guide groove 36 cooperate to limit the displacement rod 22, the displacement rod 22 will not rotate. Then the displacement rod 22 will drive the screw 23 to move along the guide rail 37 and the guide groove 36. Sliding reduces the number of flow grooves 21 blocked by the displacement rod 22 on the side wall of the connecting sleeve 20, thereby reducing the flow area in the air intake pipe 3 and changing the hot air passing speed. When it is necessary to expand the flow area in the air intake pipe 3, simply rotate the adjusting sleeve 4 in the reverse direction as described above. When the appropriate flow speed is adjusted, stop rotating the adjusting sleeve 4 and rotate the locking frame 11, locking rod 12, and other components to the corresponding position in the locking groove 16. Then, the connecting spring 13 resets and pulls the locking plate 14, causing the locking plate 14 to slide the locking rod 12 inward, so that one end of the locking rod 12 is inserted into the corresponding locking groove 16. Then, the locking sleeve 6 is released, the movable spring 35 pushes the locking sleeve 6 to slide back to its original position, and then the locking sleeve 6... The inner sliding block 33 will slide and reset along the sliding groove 34, and the locking sleeve 6 will drive the movable rod 18 on one side to slide and reset. When the movable spring 35 is fully reset, the movable rod 18 will no longer pass through the moving hole 17. At this time, the adapter spring 10 resets and pushes the adapter block 8, causing the adapter block 8 to drive the adapter rod 31 on one side to rotate and reset along the adapter hole 32. The adapter block 8 drives the moving hole 17 to rotate and reset to a position that does not correspond to the movable rod 18 through the moving plate 7. Then the movable rod 18 supports the locking sleeve 6 on one side of the moving plate 7. With the limiting of the locking sleeve 6 by the sliding block 33 and the sliding groove 34, the locking sleeve 6 will not move. Then the inner wall of the locking sleeve 6 limits the outer wall of the locking plate 14 again, so that the locking plate 14 and the locking rod 12 cannot slide outward.Then, the locking rod 12 and the locking groove 16 cooperate to limit and lock the locking frame 11, thereby preventing the locking frame 11 and the adjusting sleeve 4 from rotating accidentally. This ensures the structural stability after the hot air input flow rate is adjusted, and thus guarantees a stable hot air input.

[0041] In summary, when using or operating the equipment: When the equipment needs to be used, open the door 2 using the handle on one side of the door 2, then open the locking mechanism on the caster wheel 26, and then push the support frame 24 outwards, causing the support frame 24 to move the clothes hanger 25 out of the drying chamber 1 via the bottom caster wheel 26. Then, smooth out the clothes to be dried and hang them on the clothes hanger 25 and other external components. The clothes hanger 25 has two layers to avoid the clothes from piling up. Then, push the support frame 24 back into the drying chamber 1, and then close the locking mechanism on the caster wheel 26, so that the support frame 24 is stably stationary in the drying chamber 1. Finally, close the door 2 again, so that the interior of the drying chamber 1 and the door 2 form a relatively closed space. The sealed space is secured to one side of the drying chamber 1 using a locking mechanism commonly found in existing technologies. The heating chamber 29 is heated by its built-in resistance wire. The fan 28, mounted on the back side, draws in outside air. A filter plate 30 at the fan 28's input end filters the air to prevent foreign objects from entering. The air drawn in by the fan 28 is then transported to the heating chamber 29 for heating, becoming hot air. This hot air is then delivered to the bottom of the drying chamber 1 through the conveying pipe 5 and the air inlet pipe 3, drying the clothes from bottom to top. The hot air dries the clothes on the clothes hangers 25, ensuring efficient drying. The hot air, carrying evaporated moisture, is then discharged through the exhaust pipe 27 into subsequent collection and treatment equipment, ultimately achieving gas emission.

[0042] When the hot air input speed needs to be adjusted according to the clothing material and actual usage, first rotate the moving plate 7 clockwise. The moving plate 7 will drive the moving hole 17 and the adapter block 8 installed on one side to rotate clockwise. Then, the adapter block 8 will drive the adapter rod 31 on one side to slide along the adapter hole 32. The adapter block 8 will cooperate with the fixing block 9 to compress the adapter spring 10. When the adapter spring 10 is compressed to its limit, the moving hole 17 will rotate to a position concentric with the movable rod 18. Then, push the locking sleeve 6. The locking sleeve 6 will drive the inner sliding block 33 to slide along the sliding groove 34. The locking sleeve 6 will also drive the movable rod 18 on one side to slide into the moving hole 17, so that the inner wall of the locking sleeve 6 no longer limits the outer wall of the locking plate 14. Then, rotate the adjusting sleeve 4 clockwise to adjust. The sleeve 4 will drive the connecting spring 13, the locking rod 12, and the locking plate 14 to rotate forward via the locking bracket 11 on one side. At this time, the inner wall of the locking groove 16 will press against one end of the locking rod 12. Due to the rounded corner design of the inner wall edge of the locking groove 16 and one end of the locking rod 12, one end of the locking rod 12 will slide out of the locking groove 16, and the other end of the locking rod 12 will drive the connecting spring 13 to stretch outward via the locking plate 14. At the same time, the adjusting sleeve 4 will drive the inner threaded sleeve 15 to rotate forward. Since the threaded sleeve 15 is movably connected to the screw 23 through the thread, and the guide rail 37 and the guide groove 36 cooperate to limit the displacement rod 22, the displacement rod 22 will not rotate. Then the displacement rod 22 will drive the screw 23 to slide along the guide rail 37 and the guide groove 36. This reduces the number of flow grooves 21 blocked by the shift rod 22 on the side wall of the connecting sleeve 20, thereby reducing the flow area in the air intake pipe 3 and changing the hot air passage speed. When it is necessary to expand the flow area in the air intake pipe 3, simply rotate the adjusting sleeve 4 in the reverse direction as described above. When the appropriate flow speed is adjusted, stop rotating the adjusting sleeve 4 and rotate the locking frame 11, locking rod 12, and other components to the corresponding position in the locking groove 16. Then, the connecting spring 13 resets and pulls the locking plate 14, causing the locking plate 14 to slide the locking rod 12 inward, so that one end of the locking rod 12 is inserted into the corresponding locking groove 16. Then, the locking sleeve 6 is released, and the movable spring 35 pushes the locking sleeve 6 to slide back to its original position. Then, the locking sleeve 6 will... The inner sliding block 33 slides back to its original position along the sliding groove 34, and the locking sleeve 6 drives the movable rod 18 on one side to slide back to its original position. When the movable spring 35 is fully reset, the movable rod 18 no longer passes through the moving hole 17. At this time, the adapter spring 10 resets and pushes the adapter block 8, causing the adapter block 8 to drive the adapter rod 31 on one side to rotate back to its original position along the adapter hole 32. The adapter block 8 also drives the moving hole 17 to rotate back to its original position, which is not corresponding to the movable rod 18, through the moving plate 7. Then, the movable rod 18 supports the locking sleeve 6 on one side of the moving plate 7. With the limiting effect of the sliding block 33 and the sliding groove 34 on the locking sleeve 6, the locking sleeve 6 will not move. Then, the inner wall of the locking sleeve 6 limits the outer wall of the locking plate 14 again, so that the locking plate 14 and the locking rod 12 cannot slide outward.Then, the locking rod 12 and the locking groove 16 cooperate to limit and lock the locking frame 11, thereby preventing the locking frame 11 and the adjusting sleeve 4 from rotating accidentally. This ensures the structural stability after the hot air input flow rate is adjusted, and thus guarantees a stable hot air input.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
