Description

Technical Field

[0001] The present invention relates to the field of clothes drying, in particular to a clothes dryer. Background Art

[0002] With the acceleration of the pace of society and the increasing demand for "take-and-dry" clothes drying, various types of portable and household dryers have been widely used in homes, dormitories, travel, and outdoor settings. Existing dryers usually have a fixed air inlet on the top or side wall of the main body shell, and an air outlet on the bottom or side wall, relying on a fixed air duct between the two to achieve air circulation and hot air drying. However, the above-mentioned fixed air duct structure still has the following major shortcomings: (1) In order to ensure sufficient air intake area and circulation efficiency, the shell must reserve a large opening area and internal pipe space, resulting in an increase in the size of the entire machine, which is not conducive to small apartments, dormitories, and mobile storage. (2) If the portable dryer continues to use a fixed air inlet design, its shell size is difficult to further compress, and users find it difficult to fold or shrink the entire machine when traveling or using it outside, which seriously affects the portable experience. (3) In a high humidity environment, fixed air ducts are prone to condensation droplets or moisture accumulation. If there is no special moisture-proof coating or movable air duct structure, moisture is likely to condense on the inside of the metal or plastic shell, causing condensation in the machine cavity, breeding bacteria, affecting the drying effect and equipment life. Summary of the Invention

[0003] The object of the present invention is to provide a clothes dryer with a reduced overall volume and flexible opening and closing of the air inlet.

[0004] The object of the present invention is achieved like this: A clothes dryer comprises a main unit, a drying device, a left box part, a right box part, an air inlet seat, a circuit board and a control panel, wherein the inner and outer surfaces of the left box part and the right box part are covered with a nano-hydrophobic coating that prevents moisture condensation and is easy to clean and maintain, the left box part and the right box part are respectively connected to the main unit in a rotatable manner, and the left box part and the right box part are folded together to form a box body for storing dry clothes bags; the inner and outer surfaces of the main unit are covered with a nano-hydrophobic coating that prevents moisture condensation and is easy to clean and maintain, the top of the main unit is provided with an opening connected to the inner cavity of the main unit, and the bottom of the main unit is provided with an air outlet connected to the inner cavity of the main unit; the drying device and the circuit board are arranged in the inner cavity of the main unit, the control panel is arranged on the outer wall of the main unit, and the drying device, The control panel and the circuit board are electrically connected; the air inlet seat is a hollow air inlet seat with an open bottom, and an air inlet is provided on the side wall of the air inlet seat. The air inlet seat is movably arranged in the inner cavity of the main unit, and the left box part and the right box part are respectively mechanically linked to the air inlet seat; when the left box part and the right box part are unfolded to each other, the left box part and the right box part drive the air inlet seat to extend out of the inner cavity of the main unit along the opening direction, and at the same time, the left box part and the right box part limit the moving distance of the air inlet seat, so that part or all of the air inlets are exposed outside the inner cavity of the main unit; when the left box part and the right box part are closed to each other, the air inlet seat is retracted into the inner cavity of the main unit along the opening direction, and at the same time, the left box part and the right box part limit the moving distance of the air inlet seat, so that all the air inlets are retracted into the inner cavity of the main unit.

[0005] When clothes need to be dried, the user only needs to unfold the left and right box parts to simultaneously drive the air inlet seat to extend out of the main unit cavity, and open the air inlet to the same area and air volume as the fixed air inlet. In the storage or idle state, the user only needs to close the left and right box parts to allow the air inlet seat to automatically retract into the main unit cavity, completely hiding the air inlet and greatly reducing the thickness of the dryer. This design not only maintains efficient drying performance, but also significantly improves the portability and storage convenience of the equipment.

[0006] The left and right box parts and the inner and outer surfaces of the main unit are covered with a nano-hydrophobic coating, which effectively prevents moisture condensation and avoids problems such as internal condensation and bacterial growth in traditional dryers in high-humidity environments. At the same time, the coating surface is easy to wipe and clean, reducing daily maintenance costs and extending the service life of the equipment.

[0007] The purpose of the present invention can also be solved by the following technical measures: Furthermore, the air inlet seat also includes a dust filter assembly, which is arranged in the air inlet, and the inner wall of the air inlet located in front of the inlet of the dust filter assembly is evenly spaced with arc-shaped guide ribs arranged obliquely along the air flow direction, and the arc-shaped guide ribs are covered with a hydrophilic dust-proof coating; the dust filter assembly is detachably assembled in the air inlet, and the dust filter assembly includes a filter body and an annular frame, the filter body is assembled in the annular frame, and a flexible rubber sealing ring is arranged between the annular frame and the inner wall of the air inlet; the filter body includes a coarse filter layer, an electrostatic layer and a microfiltration layer, and the electrostatic layer is located between the coarse filter layer and the microfiltration layer; the coarse filter layer is a stainless steel woven mesh with a pore size of 200 to 500 microns; the electrostatic layer is a polarized melt-blown polypropylene non-woven fabric with permanent charge adsorption capacity; the microfiltration layer is a composite membrane formed by thermally bonding a PTFE microporous membrane and a nylon woven mesh, the thickness of the composite membrane is ≤0.5 mm, and the pore size of the composite membrane is less than 1 micron.

[0008] The multi-layered composite dust filter assembly integrated within the air inlet achieves a graded interception of lint, dust, and microorganisms: the coarse filtration layer effectively blocks large impurities, the electrostatic layer absorbs fine dust, and the microfiltration layer further captures submicron moisture and microorganisms, ensuring clean air entering the main unit cavity, thereby protecting the drying mechanism and circuit boards from contamination and extending the life of the equipment. The curved guide ribs, arranged obliquely along the airflow direction, feature a streamlined cross-section. This guides air along the inner wall during intake, creating an attached flow. This turbulent flow breaks up the boundary layer, significantly increasing the effective air intake area, thereby increasing overall airflow and facilitating faster and more evenly replenishing fresh air into the drying chamber. The hydrophilic dust-proof coating on the curved guide ribs not only reduces the adhesion of lint and dust, but also works synergistically with the three-layer composite filter assembly to ensure efficient filtration while increasing airflow and evenly distributing air, effectively improving hot air circulation efficiency, shortening drying time, and reducing energy consumption. The guide ribs can balance the air pressure distribution in each area. It also helps to reduce the local load on the filter, extend the service life of the filter and the air inlet seat, and further improve the maintenance cycle and equipment reliability. The flexible rubber sealing ring between the annular frame and the inner wall of the air inlet can fit tightly into the gap between the two, eliminating the bypass airflow of the filter, and ensuring that all air entering the main unit cavity must pass through the filter assembly, thereby greatly improving the air purification efficiency and preventing unfiltered dust and fibers from directly entering the drying chamber. The dust filter assembly is assembled in the air inlet in a detachable manner. The user can easily remove the dust filter assembly and the flexible rubber sealing ring and clean or replace them; when reinstalling, the flexible rubber sealing ring can automatically reset and quickly fit the inner wall, which not only ensures efficient sealing performance, but also greatly simplifies the maintenance process and improves the practicality and reliability of the equipment.

[0009] Furthermore, a left slide groove is provided on the left side of the air inlet seat, and the inner wall of the left slide groove is provided with a polytetrafluoroethylene coating with a low friction coefficient; the left box part is provided with a left gear component, and the left gear component is provided with a left slide rod, and the left gear component is rotatably arranged on the main unit, and the left slide rod is inserted into the left slide groove to mechanically link the left box part and the air inlet seat; a right slide groove is provided on the right side of the air inlet seat, and the inner wall of the right slide groove is provided with a polytetrafluoroethylene coating with a low friction coefficient; the right box part is provided with a right gear component, and the right gear component is provided with a right slide rod The right gear component is arranged on the main unit in a rotating manner, and the right slide rod is inserted into the right slide groove to mechanically link the right box part and the air inlet seat; a flexible linkage belt made of highly elastic and heat-resistant material is provided between the left slide rod and the right slide rod, one end of the flexible linkage belt is connected to the left slide rod, and the other end of the flexible linkage belt is connected to the right slide rod; the left gear component and the right gear component realize synchronous rotation through a meshing structure, the left gear component drives the left slide rod to move, and the right gear component drives the right slide rod to move, and the left slide rod and the right slide rod jointly push the air inlet seat to move.

[0010] This structure significantly reduces friction between the slide bar and the slot body through a low-friction polytetrafluoroethylene coating on the inner walls of the left and right slides. This allows for smooth, non-sticky movement during expansion and contraction, enhancing user experience and reducing mechanical wear. The left and right gear components engage to maintain synchronized rotation. A flexible linkage belt, secured at both ends to the ends of the left and right slide bars, is pre-tensioned during installation. Made of a heat-resistant, elastic polymer material embedded with high-strength fibers to withstand the high temperatures of the dryer, the belt is inextensible and possesses sufficient resilience. When one slide bar moves forward or backward under the gear drive, the belt seamlessly transmits this force to the other, enabling both bars to move simultaneously at the same speed and distance. At this point, the synchronizing torque is evenly distributed to both sides, completely eliminating any risk of tilting or jamming caused by one side advancing or lagging, ensuring the smooth, precise, and reliable expansion and contraction of the air inlet bar throughout its extension and contraction process.

[0011] Furthermore, it also includes a micro switch, which is electrically connected to the circuit board; the main engine inner cavity is provided with a blocking portion located outside the opening, and the micro switch is provided in the main engine inner cavity and is located next to the blocking portion; the bottom of the air inlet seat is provided with an outer flange, and the outer flange is provided with an abutment portion that cooperates with the blocking portion and the micro switch; the air inlet seat extends out of the main engine inner cavity along the opening direction until the abutment portion contacts the blocking portion, thereby limiting the maximum extension position of the air inlet seat by a contact limit method, and at the same time, the abutment portion contacts the touch rod of the micro switch, and the micro switch feeds back a signal to the circuit board, and the circuit board turns on the power of the drying device.

[0012] By providing a supporting part on the outer edge of the bottom of the air inlet seat that cooperates with the blocking part of the main unit, physical limiting is achieved through mechanical contact. Without the need for additional travel switches or auxiliary structures, the maximum extension position of the air inlet seat can be accurately limited, ensuring that all air inlets are exposed, and ensuring the stability of air intake volume and drying efficiency.

[0013] When the abutting parts touch the touch rod of the micro switch at the same time, the micro switch will quickly feed back the arrival signal to the circuit board, and the circuit board will automatically turn on the power of the drying device to avoid safety hazards caused by user misoperation or starting the equipment when the air inlet seat is not fully unfolded.

[0014] Through the dual protection of mechanical limiting and electrical interlocking, the present invention not only optimizes the operating process and user experience, but also improves the intelligence level of the dryer, effectively preventing air duct blockage, heating component overload and energy waste caused by "semi-expanded start-up", extending the life of the entire machine and reducing maintenance costs.

[0015] Furthermore, it also includes a sealed box body injection-molded from high-temperature resistant and flame-retardant PC material, which is arranged in the inner cavity of the main unit and is adjacent to the blocking part; the inner wall of the sealed box body is covered with a nano-hydrophobic coating, and the box wall of the sealed box body is provided with breathable micropores, and the breathable micropores are covered with a PTFE film that allows gas exchange and blocks water mist and fiber dust; the bottom plate of the sealed box body is an outward-inclined inclined panel with a drain outlet, and the inclined panel has drainage grooves spaced apart along the inclined direction, and the bottom end of the drainage groove is connected to the drain outlet; the drain outlet is equipped with a one-way diversion valve, and the one-way diversion valve includes at least two umbrella-shaped silicone valve pieces. The composition is that one end of the umbrella-type silicone valve disc is fixedly arranged on the inner side of the drain outlet, and the other end is freely attached to another umbrella-type silicone valve disc; when water droplets in the sealed box body flow to the drain outlet through the drain groove, gravity causes the umbrella-type silicone valve disc to open, thereby discharging the accumulated water; when external water vapor or water mist attempts to enter in the opposite direction, the umbrella-type silicone valve disc closes the drain outlet under the action of elasticity, thereby blocking the backflow of gas and water mist; the micro switch is arranged in the sealed box body, and the inclined panel of the sealed box body is provided with an operating port, and the touch rod of the micro switch passes through the operating port and extends out of the sealed box body, and a silicone sealing ring is arranged between the operating port and the touch rod.

[0016] The sealed enclosure, constructed from high-temperature-resistant, flame-retardant PC material and coated with a nano-hydrophobic coating on its inner walls, effectively blocks moisture and condensation from entering the drying process, preventing the microswitch from malfunctioning or failing due to moisture or contamination. This structure provides long-term dry protection for the microswitch in high-humidity environments, significantly improving the stability and service life of the limit detection system.

[0017] The combination of the breathable micropores of the sealed box and the PTFE film covering it ensures both gas exchange and dust and fog protection. This balances the air pressure inside and outside the sealed box while preventing lint and water mist from entering the sealed box, ensuring the accuracy and long-term stability of the switch signal. Furthermore, the PTFE film effectively blocks water vapor and condensation from penetrating the box through the micropores, preventing the microswitch from failing or being accidentally triggered due to moisture infiltration, thereby significantly enhancing the reliability and service life of the limit detection system in high-humidity working environments.

[0018] The silicone sealing ring between the operating port and the touch rod can tightly seal the gap during the drying process, effectively preventing water vapor and condensation from penetrating into the sealed box body, and preventing the micro switch from failing or malfunctioning due to moisture infiltration, thereby significantly improving the reliability and service life of the limit detection system.

[0019] The inclined drainage panel, combined with the multi-section drainage groove and the umbrella-type one-way diversion valve, realizes the automatic directional discharge of condensed water droplets in the box body. The valve plate structure with gravity trigger opening and elastic reset closing can prevent the backflow of external water vapor, effectively avoiding moisture intrusion into the box body and causing micro switch short circuit or detection malfunction.

[0020] Furthermore, the air inlet seat includes a seat body with an open bottom and a hollow interior, a blocking block, a damping column and a spring, the seat body is provided with a transversely arranged sliding channel, the inner wall of the sliding channel is provided with a polytetrafluoroethylene coating with a low friction coefficient; the damping column includes a metal core shaft and a polyurethane composite buffer layer coated on the outer periphery of the metal core shaft, and the damping column is arranged in the sliding channel; the blocking block is an L-shaped blocking block, the blocking block includes a pressing portion located outside the sliding channel and a connecting portion that can be slidably fitted in the sliding channel, and the pressing portions are spaced apart. The air inlet; the spring is placed in the sliding channel and sleeved on the outer periphery of the damping column, one end of the spring abuts against the connecting part, and the other end of the spring abuts against the inner wall of the sliding channel, and the spring constitutes a reset mechanism of the blocking block; the host is provided with a limiting step at the inner wall of the opening, and the limiting step is provided with a guiding inclined surface inclined toward the opening; when the air inlet seat extends out of the inner cavity of the host along the opening direction, the elastic force of the spring pushes the blocking block to move outward until the pressing part of the blocking block elastically abuts against the guiding inclined surface of the limiting step, thereby preventing the air inlet seat from sliding down due to gravity.

[0021] By setting up a sliding limit mechanism composed of a damping column with a buffer layer and a spring, the air inlet seat can be automatically locked by elastic force after extending out of the main unit cavity. The spring pushes the pressing part of the blocking block against the guide inclined surface of the limiting step of the main unit, effectively preventing the air inlet seat from falling back by itself due to gravity, thereby ensuring its stable working position.

[0022] When the air inlet seat is forced downward by external force (for example, by the user forcibly rotating the left or right housing, causing it to slide downward), the pressing portion slides smoothly along the guide slope, compressing the spring and driving the block to unlock, allowing the air inlet seat to automatically retract to the predetermined position within the main unit cavity. This design not only effectively protects the air inlet seat and the reset mechanism from jamming or damage caused by forced operation, but also prevents damage to the internal structure caused by user error, thereby improving the safety and durability of the entire device. Furthermore, a polytetrafluoroethylene coating is used between the block and the sliding channel to significantly reduce friction, ensuring a smooth sliding process and preventing jamming.

[0023] Furthermore, a sunken step is provided on the top of the main unit at the periphery of the opening; the air inlet seat also includes a top cover, and the air inlet is opened on the side wall of the seat body. The size of the top cover is larger than the size of the seat body. The top cover is arranged on the top of the seat body, and an outer extension is formed at the edge of the top cover at the periphery of the seat body. The seat body is retracted into the inner cavity of the main unit, and the outer extension rests on the sunken step.

[0024] This structure achieves interlocking positioning by setting a sunken step on the top of the main unit and cooperating with the outer edge of the air inlet seat top cover, effectively improving the sealing performance of the air inlet seat when it is stored. At the same time, the outer edge and the sunken step form an air inlet seat limiting structure without additional buckles, thereby improving the reliability and service life of the entire machine.

[0025] Furthermore, a hooking device is provided on the top of the air inlet seat or the main unit.

[0026] A hook device is set on the air inlet seat or the top of the main unit, so that the whole machine can be flexibly hung on the back of the door, clothes rod, wall hook and other narrow or space-restricted places during use, which greatly improves the applicable scenarios and space utilization of the drying equipment and meets the diverse usage needs of users.

[0027] Furthermore, the hooking device includes a hook body and a rod body, and the hook body and the rod body are connected; a rod body accommodating groove is opened on the top of the air inlet seat, and a hook body accommodating groove is opened on the top of the main unit, and the rod body is connected to the rod body accommodating groove in a rotatable manner; the air inlet seat is retracted into the inner cavity of the main unit, and the rod body accommodating groove and the hook body accommodating groove are connected, and the hooking device is rotated, the rod body is placed in the rod body accommodating groove, and the hook body is placed in the hook body accommodating groove.

[0028] By providing a rod- and hook-receiving slot on the air inlet and top of the main unit, respectively, and allowing the hook to fold or unfold within the slots by rotating, this structure achieves both concealed storage and one-touch deployment of the hook. When stored, the hook is completely concealed within the dryer body, maintaining a simple and aesthetically pleasing appearance while also avoiding the risk of damage from an exposed hook. When deployed, a simple rotation precisely positions the rod and hook outside the slots, making it easy to hook the dryer.

[0029] Furthermore, the device further comprises a clothes hanger for hanging clothes, a humidity sensor, and a temperature sensor, the clothes hanger being arranged on the main unit and located below the air outlet; the drying device being smaller than the inner cavity of the air inlet seat and being arranged below the opening of the main unit; the drying device comprising a fan and a heating component, each of which is electrically connected to a circuit board; the air inlet seat extending out of the inner cavity of the main unit through the opening, the hollow cavity of the air inlet seat forming an air passage; the humidity sensor and the temperature sensor being arranged in the inner cavity of the main unit and located above the air outlet, each of which is electrically connected to the circuit board, the detection surfaces of the humidity sensor and the temperature sensor facing the air outlet, the humidity sensor and the temperature sensor respectively feeding back real-time humidity and temperature signals to the circuit board, and the circuit board dynamically adjusting the fan speed and the heating component power based on the signals. When the air inlet seat retracts into the inner cavity of the main unit through the opening, the drying device automatically slides into the hollow cavity of the air inlet seat through the open bottom opening of the air inlet seat for storage.

[0030] When the air inlet seat is extended and in working state, the fan and the heating component face the open bottom of the hollow cavity, forming an efficient straight air duct, thereby achieving an efficient drying path in which the heated air flows through the clothes and is evenly discharged from the air outlet; When the air inlet seat is retracted into the main unit cavity, the drying device can slide into the air inlet seat cavity as a whole, effectively reducing the thickness and volume of the entire machine and improving the convenience of storage.

[0031] The clothes hanging rod is set directly below the air outlet, which not only provides users with structural support for directly hanging clothes to be dried, but also ensures that the air flow reaches the surface of the clothes directly, avoiding waste of heat and wind power, and further improving drying efficiency.

[0032] By integrating temperature and humidity sensors to collect real-time data about the drying chamber's internal environment and feeding the signals back to the circuit board, the system automatically adjusts fan speed and heating power based on current humidity and temperature, achieving intelligent control. This dynamic adjustment not only improves drying efficiency but also prevents overheating, overdrying, and excessive energy consumption, significantly enhancing equipment safety, energy efficiency, and clothing care effectiveness.

[0033] The beneficial effects of the present invention are as follows: The clothes dryer of the present invention adopts a structural design in which the left and right box parts can be rotatably expanded / closed, combined with a linkage sliding out and retraction mechanism of the air inlet seat. Through structures such as sliding rods, gears and flexible linkage belts, an air inlet channel is automatically formed when the main unit is expanded, and it is compactly stored when closed, which greatly reduces the size of the equipment, facilitates hanging use and daily storage, does not occupy home space, and is suitable for users of small apartments.

[0034] The present invention is equipped with a triple composite filtration system and an arc-shaped guide rib structure in the air inlet seat, which effectively intercepts large particles of impurities, fine suspended particles and microorganisms, ensuring the cleanliness of the air sent to the host. At the same time, it improves the stability of the air path, reduces the airflow noise, prevents dust from entering the interior of the host and damaging electrical components, and improves product durability and clothing hygiene.

[0035] In the present invention, the main unit is provided with humidity and temperature sensors, with the detection surface facing the air outlet, so as to sense the internal environmental data of the drying bag in real time, and intelligently adjust the fan speed and heating power through the circuit board, dynamically adapting to the dryness and wetness of the clothes, realizing "fast and economical" intelligent drying, avoiding overheating and overdrying, extending the life of the clothes, and reducing energy consumption.

[0036] In this invention, when the air inlet seat extends out of the main unit's outer cavity along the opening, its abutment slides to the blocking position. Mechanical contact forms a clear physical limit, limiting the maximum extension range of the air inlet seat. At this time, the abutment simultaneously presses the touch lever of the microswitch, which sends a signal to the circuit board, which confirms that the air inlet seat is fully extended and allows the drying device to start operation, thus achieving electrical position confirmation and safety interlocking.

[0037] In order to prevent the air inlet seat from sliding down due to its own weight or vibration during use, the present invention is designed with a locking mechanism that pushes the blocking block with a spring. The spring uses elastic force to elastically force the pressing portion of the blocking block against the guide slope of the limiting step, generating a locking torque, which mechanically locks the air inlet seat firmly to prevent it from sliding down due to gravity. When the air inlet seat is forced to move downward by an external force (for example, the user forcibly rotates the left or right box part, causing the air inlet seat to slide down), the pressing portion can slide smoothly along the guide slope, squeeze the spring, drive the blocking block to release the lock, and automatically retract the air inlet seat to the predetermined position in the main unit cavity. This design not only effectively protects the air inlet seat and the reset mechanism from being stuck or damaged due to forced operation, but also prevents the user from damaging the internal structure of the device due to misoperation, thereby improving the safety and durability of the entire machine.

The left and right box portions 3, 4 are folded together to form a box for storing dry clothes bags. The inner and outer surfaces of the main unit 1 are covered with a nano-hydrophobic coating that prevents moisture condensation and facilitates cleaning and maintenance. The top of the main unit 1 is provided with an opening 11 connected to the inner cavity of the main unit 1, and the bottom of the main unit 1 is provided with an air outlet 12 connected to the inner cavity of the main unit 1. The drying device 2 and the circuit board 30 are disposed in the inner cavity of the main unit 1, and the control panel is disposed on the outer wall of the main unit 1. The drying device 2, the control panel, and the circuit board 30 are electrically connected. The air inlet seat 5 is a hollow air inlet seat with an open bottom, and an air inlet 51 is provided on the side wall of the air inlet seat 5.

[0066] How to use the clothes dryer: When the user needs to use the clothes dryer for drying, first, the user rotates the hook device 10 upward and unfolds it, so that the hook body 101 flips from the hook body receiving slot 16 to the hanging position. Then, the user hangs the hook body 101 on a support such as a wardrobe rod, hook, or door back rod to ensure that the main unit 1 is stably suspended.

[0067] Then, the user holds the left box part 3 or the right box part 4 to open it, and the gear transmission drives the left box part 3 and the right box part 4 to rotate and unfold synchronously, so that the left slide bar 311 and the right slide bar 411 jointly drive the air inlet seat 5 to extend out of the inner cavity of the main unit 1 along the direction of the opening 11 until the abutment 55 contacts the blocking part 13, thereby limiting the maximum extension position of the air inlet seat 5 by the contact limit method, and at the same time, the abutment 55 contacts the touch rod 71 of the microswitch 7, and the microswitch 7 feeds back a signal to the circuit board 30, the circuit board 30 turns on the power of the drying device 2, and the elastic force of the spring 58 pushes the blocking block 9 to move outward until the pressing part 91 of the blocking block 9 elastically abuts against the guide slope 141 of the limiting step 14, thereby preventing the air inlet seat 5 from sliding down due to gravity, ensuring that it remains in a stable unfolded state during operation.

[0068] The user then attaches a drying bag to the left and right sections 3 and 4 to form a closed or semi-enclosed space. The user then places the clothes to be dried into the drying bag and hangs them on the clothes hanger 20, positioning them directly below the air outlet 12. The user activates the drying device 2 via the control panel, and the fan 21 begins to operate at high speed, drawing in outside air through the air inlet 51 through negative pressure. The air is first guided by the curved guide ribs 511, which stabilize the airflow, reduce turbulence and noise, and improve air flow efficiency.

[0069] Next, the air enters the dust filter assembly 6 and undergoes three layers of filtration in sequence: the first coarse filtration layer 611 intercepts large particles of impurities such as hair and fibers; the second electret electrostatic layer 612 captures fine suspended particles through electrostatic adsorption; the third microfiltration layer 613 is a microporous PTFE membrane with extremely fine pores, which effectively blocks dust and microorganisms, ensuring that the air delivered into the interior is clean and pollution-free.

[0070] Filtered clean air enters the heating element 22 through the air duct, where it is heated to form constant-temperature hot air. This air is then steadily blown into the drying bag through the air outlet 12 at the bottom of the main unit 1. The hot air circulates within the drying bag, focusing around the clothing and accelerating the evaporation of moisture from the surface and interior of the clothing. The drying bag acts as a wind collector and dust barrier, while also suppressing heat loss. Temperature and humidity sensors monitor the bag's internal environment in real time and dynamically feed this data back to the circuit board 30. Based on this data, the circuit board 30 adjusts the fan 21's speed and heating power, achieving energy-efficient and efficient intelligent drying.

[0071] After the drying process is complete, the user turns off the dryer, removes the clothes, and then removes the dryer bag and stores them. Next, the user presses the pressing portion 91 of the stopper 9, causing it to rebound inward and disengage the guide slope 141 of the stop step 14. The user then pushes the air inlet seat 5 along the opening 11 and into the interior of the main unit 1. The existing sliding rod and gear transmission mechanism then rotate the left and right housing sections 3 and 4 together, closing the housing.

[0072] Finally, the user rotates the hook device 10 in the opposite direction, so that the hook body 101 is retracted into the hook body receiving groove 16, and the rod body 102 is retracted into the rod body receiving groove 59. The entire dryer is restored to a compact storage state, which is convenient for putting it back into the storage space, completing the entire use process.

[0073] The advantages of installing the micro switch 7 inside the sealed box body 8 are as follows: the sealed box body 8 is provided with breathable micropores 81 with a PTFE film 82, which can effectively isolate moisture and water mist, prevent the switch from being oxidized by moisture and contact failure, and at the same time block the fiber dust generated during the clothes drying process from entering, avoiding the switch from being stuck or triggered by mistake.

[0074] The sealed box body 8 is also provided with a drainage groove and a one-way diversion valve 85. Even if water vapor condenses into water droplets, it can be discharged smoothly to keep the switch working area dry and clean.

[0075] In addition, this enclosed structure can also centrally house electrical components, creating a safer and more stable electrical control environment and preventing the spread of arcs or faults. The overall design not only extends the life of the micro switch 7 and related electrical components, but also greatly improves the reliability and safety of the dryer in humid and high-temperature environments.

[0076] The benefits of outside air being guided by curved guide ribs and filtered through dust filter assembly 6 before entering the dryer's internal cavity for heating are as follows: Before entering the dryer, outside air is first guided by the curved guide ribs, effectively optimizing airflow direction, reducing turbulence and noise, and improving air intake efficiency. It is then filtered by dust filter assembly 6, effectively blocking dust, lint, and fiber particles in the air, preventing impurities from entering the dryer. This process not only ensures cleaner air entering the drying system, but also helps maintain the long-term cleanliness of the heating elements and air ducts, reducing maintenance frequency, improving heat exchange efficiency and overall drying performance, and extending the life of key internal components.

[0077] The combination of a gear meshing structure and a flexible linkage belt 54 provides the following benefits: The left and right slide bars 311 and 411 achieve efficient, synchronized linkage, ensuring balanced, coordinated movement of both sides when the user rotates the left or right housing section 3 or 4 to expand or close them. This prevents tilting, jamming, or misalignment of the air inlet seat 5 due to unilateral force. This structure ensures linear movement of the air inlet seat 5, enhancing the dryer's ease of use and durability while reducing the risk of wear and failure due to structural imbalance.

[0078] In other embodiments, the flexible linkage belt 54 includes an aramid fiber webbing for bearing tensile loads and maintaining deformation stability and a thermoplastic polyurethane coating layer formed by hot pressing to provide flexibility, anti-slip and wear resistance, and the thermoplastic polyurethane coating layer covers the aramid fiber webbing; the outer surface of the thermoplastic polyurethane coating layer is provided with anti-slip ribs to prevent slipping and deviation, and the thermoplastic polyurethane coating layer is integrally formed with the aramid fiber webbing by a hot pressing co-extrusion process, and the adhesion between the thermoplastic polyurethane coating layer and the aramid fiber webbing is not less than 1.5 N / mm; the aramid fiber webbing is a multi-strand interlaced woven structure, the width of the aramid fiber webbing is 8-15 mm, and the thickness of the aramid fiber webbing is 0.2-0.6 The end of the flexible linkage belt 54 is provided with a metal reinforcement clamp for connecting the left slide bar or the right slide bar, and the metal reinforcement clamp is made of stainless steel or aluminum alloy, and the metal reinforcement clamp is fixedly connected to the end of the flexible linkage belt 54 by stamping and riveting.

[0079] The flexible linkage belt 54 structure, by coating the outer layer of the aramid fiber webbing with thermoplastic polyurethane material, not only achieves high-strength load-bearing and excellent deformation stability, but also takes into account good flexibility and wear resistance, effectively improving the reliability and service life of the linkage system. The aramid fiber webbing adopts a multi-strand interlaced braid structure, which enhances the overall tensile and tear resistance while maintaining a soft feel. It can adapt to the high-frequency repeated loads during the multiple extension and retraction movements of the dryer and is not easily deformed or broken. The thermoplastic polyurethane coating layer is integrally formed with the aramid webbing through a hot-pressing co-extrusion process to ensure a close bond between the materials, with an adhesion of more than 1.5 N / mm, which can effectively prevent peeling or delamination between the coating layer and the webbing due to long-term use. At the same time, the anti-skid rib structure provided on its outer surface can enhance the friction between the pulley or slide, preventing the flexible linkage belt 54 from slipping or deflecting during the transmission process, and ensuring the precise and smooth synchronous expansion and closing of the left and right slide bars. Furthermore, the flexible linkage belt 54 is equipped with metal reinforcement clips at both ends. These are made of stainless steel or aluminum alloy and secured to the belt body via stamping and riveting. This not only increases the structural strength of the connection, but also ensures a secure and reliable connection, preventing loosening, displacement, or breakage during long-term operation, further enhancing the safety and durability of the entire transmission system. In summary, the flexible linkage belt 54, combining high-strength materials with a non-slip design, not only meets the requirements of the dryer's high-humidity, high-temperature, and multiple-tension operating conditions, but also exhibits excellent formability and assembly stability, making it a key component for enhancing the performance of the linkage transmission system and the reliability of the entire unit.
