Description

TECHNICAL FIELD

[0001] The present application relates to the field of drying clothes, in particular to a clothes dryer. BACKGROUND

[0002] With the acceleration of social rhythm and the increasing demand of users for "on-demand" clothes drying, various portable and household clothes dryers have been widely used in families, dormitories, and travel and outdoor scenarios. The existing clothes dryers usually have a fixed air inlet on the top or side wall of the main shell, and an air outlet on the bottom or side wall, and rely 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 main deficiencies: (1) In order to ensure sufficient air inlet area and flow efficiency, the shell must reserve a larger opening area and internal pipeline space, resulting in an increase in the size of the whole machine, which is not conducive to small-sized homes, dormitories and mobile storage. (2) If the portable clothes dryer follows the fixed air inlet design, the size of the shell is difficult to further compress, and the user is difficult to fold or zoom the whole machine when using it on travel or outing, which seriously affects the portable experience. (3) In a high humidity environment, the fixed air duct is easy to produce condensation water droplets or moisture accumulation. If there is no special moisture-proof coating or movable air duct structure, moisture is easy to condense on the inside of the metal or plastic shell, resulting in machine cavity condensation, breeding bacteria, affecting the drying effect and equipment life. SUMMARY

[0003] The purpose of the present application is to provide a clothes dryer with reduced overall size and flexible opening and closing of the air inlet.

[0004] The purpose of the present application is achieved as follows:

[0005] The application discloses a clothes dryer, which comprises a main machine, a drying device, a left box part, a right box part, an air inlet seat, a circuit board and a control panel, the inner and outer surfaces of the left box part and the right box part are covered with a nano-hydrophobic coating which prevents moisture condensation and is easy to clean and maintain, the left box part and the right box part are rotatably connected to the main machine respectively, and the left box part and the right box part are folded to form a box body for storing a clothes drying bag; the inner and outer surfaces of the main machine are covered with a nano-hydrophobic coating which prevents moisture condensation and is easy to clean and maintain, an opening communicating with an inner cavity of the main machine is arranged at the top of the main machine, and an air outlet communicating with the inner cavity of the main machine is formed in the bottom of the main machine; the drying device and the circuit board are arranged in the inner cavity of the main machine, the control panel is arranged on the outer wall of the main machine, 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, air inlets are formed in the side walls of the air inlet seat, the air inlet seat is movably arranged in the inner cavity of the main machine, and the left box part and the right box part are mechanically connected with the air inlet seat in linkage; when the left box part and the right box part are unfolded, the left box part and the right box part drive the air inlet seat to extend out of the inner cavity of the main machine along the opening direction, and meanwhile, 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 out of the inner cavity of the main machine; when the left box part and the right box part are folded, the air inlet seat is retracted into the inner cavity of the main machine along the opening direction, and meanwhile, 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 machine.

[0006] When clothes need to be dried, a user only needs to unfold the left box part and the right box part to drive the air inlet seat to extend out of the inner cavity of the main machine, so that the air inlets are opened to the same area and air volume as the fixed air inlets; and in the storage or idle state, the user only needs to fold the left box part and the right box part to drive the air inlet seat to automatically retract into the inner cavity of the main machine, so that the air inlets are completely hidden, and the thickness of the clothes dryer is greatly reduced; the design not only maintains the high-efficiency drying performance, but also significantly improves the portability and storage convenience of the equipment.

[0007] The inner and outer surfaces of the left box part, the right box part and the main machine are covered with the nano-hydrophobic coating, so that moisture condensation is effectively prevented, and problems such as internal condensation and bacterial breeding of the traditional clothes dryer in a high-humidity environment are avoided; meanwhile, the surface of the coating is easy to wipe and clean, the daily maintenance cost is reduced, and the service life of the equipment is prolonged.

[0008] The object of the application can also be solved by the following technical measures:

[0009] Further, the air inlet seat further comprises a dustproof filter screen assembly, the dustproof filter screen assembly is arranged in the air inlet, arc-shaped flow guide ribs which are arranged in a slanting manner along the airflow direction are uniformly and spacedly distributed on the inner wall of the air inlet in front of the entrance of the dustproof filter screen assembly, the arc-shaped flow guide ribs are covered with a hydrophilic dustproof coating; the dustproof filter screen assembly is detachably assembled in the air inlet, the dustproof filter screen assembly comprises a filter screen body and an annular frame, the filter screen 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 screen body comprises a coarse filter layer, an electrostatic layer and a micro filter layer, the electrostatic layer is located between the coarse filter layer and the micro filter layer; the coarse filter layer is a stainless steel woven mesh with a pore size of 200-500 microns; the electrostatic layer is an electret melt-blown polypropylene non-woven fabric which has permanent charge adsorption capacity; the micro filter layer is a composite membrane formed by hot bonding of a PTFE microporous membrane and a nylon woven mesh, the thickness of the composite membrane is less than or equal to 0.5 millimeter, and the pore size of the composite membrane is less than 1 micron.

[0010] By integrating the multi-layer composite dustproof filter screen assembly in the air inlet, the hierarchical interception of fiber dust, dust and microorganisms is realized: the coarse filter layer effectively blocks large-particle impurities, the electrostatic layer adsorbs fine dust, and the micro filter layer further traps submicron-level moisture and microorganisms, ensuring that the air entering the main cavity is clean, thereby protecting the drying device and the circuit board from contamination and prolonging the service life of the equipment. The arc-shaped flow guide ribs arranged in a slanting manner along the airflow direction have a streamlined cross-sectional design, which can guide the air to adhere to the inner wall to form a boundary layer when the air is inhaled, and break the boundary layer through the effect of flow disturbance, significantly increasing the effective air inlet area, thereby improving the air inlet volume of the whole machine and helping to faster and more evenly supplement fresh air to the drying cavity. The hydrophilic dustproof coating covering the arc-shaped flow guide ribs not only reduces the adhesion probability of lint and dust, but also cooperates with the three-layer composite filter screen assembly to effectively improve the hot air circulation efficiency, shorten the drying time and reduce the energy consumption while ensuring efficient filtration through the increased air inlet volume and uniform airflow distribution. The flow guide ribs can balance the air pressure distribution in each region, and they also help to reduce the local load of the filter screen, prolong the service life of the filter screen 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 tightly fit the gap between the two, eliminating bypass airflow of the filter screen, and ensuring that all air entering the main cavity of the machine must pass through the filter screen assembly, thereby greatly improving the air purification efficiency and preventing unfiltered dust and fibers from directly entering the drying cavity. The dustproof filter screen assembly is detachably assembled in the air inlet, so that the user can easily remove the dustproof filter screen assembly and the flexible rubber sealing ring for cleaning or replacement; when reinstalling, the flexible rubber sealing ring can automatically reset and quickly fit the inner wall, which not only ensures high sealing performance, but also greatly simplifies the maintenance process and improves the practicality and reliability of the equipment.

[0011] Further, the left side of the air inlet base is provided with a left sliding groove, and the inner wall of the left sliding groove is provided with a polytetrafluoroethylene coating with low friction coefficient; the left box part is provided with a left gear part, and the left gear part is provided with a left sliding rod; the left gear part is rotatably arranged on the main machine, and the left sliding rod is inserted into the left sliding groove, so that the left box part and the air inlet base are mechanically connected in linkage; the right side of the air inlet base is provided with a right sliding groove, and the inner wall of the right sliding groove is provided with a polytetrafluoroethylene coating with low friction coefficient; the right box part is provided with a right gear part, and the right gear part is provided with a right sliding rod; the right gear part is rotatably arranged on the main machine, and the right sliding rod is inserted into the right sliding groove, so that the right box part and the air inlet base are mechanically connected in linkage; a flexible linkage belt made of high-elastic heat-resistant material is arranged between the left sliding rod and the right sliding rod, one end of the flexible linkage belt is connected to the left sliding rod, and the other end of the flexible linkage belt is connected to the right sliding rod; the left gear part and the right gear part are synchronously rotated through the meshing structure, the left gear part drives the left sliding rod to move, the right gear part drives the right sliding rod to move, and the left sliding rod and the right sliding rod jointly push the air inlet base to move.

[0012] The polytetrafluoroethylene low-friction coating on the inner walls of the left and right sliding grooves significantly reduces the frictional resistance between the sliding rods and the groove bodies, making the air inlet base move smoothly and without jamming during the unfolding and folding processes, improving the user's operation experience and reducing mechanical wear. The left and right gear parts are synchronously rotated through meshing, and the two ends of the flexible linkage belt are fixed at the ends of the left and right sliding rods. The flexible linkage belt is adjusted to an appropriate pre-tightening force during installation. The flexible linkage belt is made of heat-resistant elastic polymer material with high-strength fibers and can withstand the high-temperature environment of the clothes dryer. The flexible linkage belt cannot be elongated and has sufficient elastic force. When one sliding rod moves forward or backward under the drive of the gear, the flexible linkage belt immediately transmits this movement force to the other sliding rod without any gap, so that the two sliding rods move at the same speed and distance at the same time. At this moment, the synchronous torque is evenly distributed to the left and right sides, completely eliminating any risk of tilting and jamming caused by unilateral advance or lag, thereby ensuring that the air inlet base always moves smoothly, accurately and reliably during the entire extension and folding process.

[0013] Further, a micro switch is further included, and the micro switch is electrically connected with the circuit board; the main machine inner cavity is provided with a blocking part around the opening, and the micro switch is arranged in the main machine inner cavity and located beside the blocking part; the bottom of the air inlet base is provided with an outward turning edge, and the outward turning edge is provided with an abutting part matched with the blocking part and the micro switch; the air inlet base is extended out of the main machine inner cavity along the opening direction until the abutting part contacts the blocking part, so as to limit the maximum extension position of the air inlet base through contact limiting, and at the same time, the abutting part contacts the touch rod of the micro switch, the micro switch feeds back a signal to the circuit board, and the circuit board turns on the power supply of the drying device.

[0014] By setting the abutting part on the outer flange of the bottom of the air inlet seat to cooperate with the blocking part of the main machine, mechanical contact is used to achieve physical limiting, without additional travel switches or auxiliary structures, so as to accurately limit the maximum extension position of the air inlet seat, ensure that all air inlets are exposed, and ensure the stability of the air intake and drying efficiency.

[0015] When the abutting part touches the touch rod of the micro switch at the same time, the micro switch rapidly feeds back the in-place signal to the circuit board, and the circuit board automatically turns on the power supply of the drying device, thereby avoiding the safety hazards caused by starting the device when the air inlet seat is not fully expanded or the user misoperates.

[0016] Through the double protection of mechanical limiting and electrical interlocking, the present application not only optimizes the operation process and user experience, but also improves the intelligent level of the drying machine, effectively prevents the air duct blockage, heating component overload and energy waste caused by "half-expansion start", prolongs the service life of the whole machine and reduces the maintenance cost.

[0017] Further, it also includes a sealing box body made of high-temperature-resistant and flame-retardant PC material, which is injection molded, the sealing box body is arranged in the inner cavity of the main machine and is adjacent to the blocking part, the inner wall of the sealing box body is covered with a nano hydrophobic coating, the box wall of the sealing box body is provided with a gas permeable micropore, the gas permeable micropore is attached with a PTFE film that allows gas exchange but blocks water mist and fiber dust, the bottom plate of the sealing box body is an inclined plane with a drainage port, the inclined plane is provided with a drainage groove along the inclined direction, and the bottom end of the drainage groove is communicated with the drainage port, the drainage port is provided with a one-way flow valve, the one-way flow valve includes at least two umbrella-shaped silica gel valve pieces, one end of the umbrella-shaped silica gel valve piece is fixed to the inner side of the drainage port, and the other end is freely attached to another umbrella-shaped silica gel valve piece, when water droplets in the sealing box body flow to the drainage port through the drainage groove, gravity causes the umbrella-shaped silica gel valve piece to open, thereby draining the accumulated water, when external water vapor or water mist tries to enter in the opposite direction, the umbrella-shaped silica gel valve piece tightly closes the drainage port under the action of elasticity, thereby blocking the backflow of gas and water mist, the micro switch is arranged in the sealing box body, the inclined plane of the sealing box body is provided with an operation port, the touch rod of the micro switch extends out of the sealing box body through the operation port, and a silica gel sealing ring is arranged between the operation port and the touch rod.

[0018] The sealing box body made of high-temperature-resistant and flame-retardant PC material, combined with the nano hydrophobic coating on its inner wall, can effectively block the water vapor and condensation in the drying process from entering the box body, preventing the micro switch from being damp or wet and causing malfunction or failure. This structure provides long-term dry protection for the micro switch in a high-humidity environment, significantly improving the stability and service life of the limiting detection system.

[0019] The air-permeable micropores of the sealed box body are combined with the PTFE film covering thereon, which takes into account the gas exchange and dust and fog prevention functions, can balance the air pressure inside and outside the sealed box body, and can block the fiber dust and water mist from entering the sealed box body, thereby ensuring the accuracy and long-term stability of the switch signal, and the PTFE film can also effectively block the water vapor and condensed liquid from penetrating into the box body through the micropores, thereby preventing the micro switch from being inactivated or malfunctioning due to moisture infiltration, and greatly enhancing the reliability and service life of the limit detection system in a high-humidity working environment.

[0020] The silica gel sealing ring between the operation port and the touch rod can tightly close the gap during the drying process, effectively block the water vapor and condensed liquid from penetrating into the sealed box body, and prevent the micro switch from being inactivated or malfunctioning due to moisture infiltration, thereby significantly improving the reliability and service life of the limit detection system.

[0021] The inclined drainage slope plate cooperates with the multi-section drainage groove and the umbrella-shaped one-way guide valve to realize the automatic directional discharge of the condensed water droplets in the box body, the gravity triggers the opening and the elastic reset closes the valve plate structure, which can prevent the external water vapor from flowing back, and effectively prevent the moisture from entering the box body to cause the micro switch to be short-circuited or the detection to be malfunctioned.

[0022] Further, the air inlet seat includes a bottom-opened and hollow seat body, a blocking block, a damping column and a spring, the seat body is provided with a sliding channel arranged transversely, and 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 wrapped around 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, which includes a pressing portion outside the sliding channel and a connecting portion slidably fitted in the sliding channel, and the pressing portion is spaced apart from the air inlet; the spring is arranged in the sliding channel and wrapped around the outer periphery of the damping column, one end of the spring abuts against the connecting portion, 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 main machine is provided with a limiting step at the inner wall of the opening, and the limiting step is provided with a guide slope inclined toward the opening; when the air inlet seat extends out of the inner cavity of the main machine along the opening direction, the spring pushes the blocking block to move outward, until the pressing portion of the blocking block elastically abuts against the guide slope of the limiting step, thereby preventing the air inlet seat from sliding downward due to gravity.

[0023] By arranging the sliding limiting mechanism composed of the damping column with a buffer layer and the spring, the air inlet seat can be automatically locked after extending out of the cavity of the main machine by the elastic force, the pressing portion of the blocking block is abutted against the guide slope of the limiting step of the main machine, which effectively prevents the air inlet seat from falling back by gravity, and ensures the stability of the working position.

[0024] When the air inlet seat is forced to move downward by external force (for example, the user forcibly rotates the left box part or the right box part to cause the air inlet seat to slide downward), the pressing part can smoothly slide along the guide inclined surface, extrude the spring, drive the blocking block to be unlocked, and automatically retract the air inlet seat to the predetermined position in the inner cavity of the main machine. 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 equipment due to misoperation, thereby improving the safety and durability of the whole machine. At the same time, the blocking block and the sliding channel are coated with polytetrafluoroethylene, which significantly reduces the frictional resistance and makes the sliding process smooth, thereby avoiding the occurrence of sticking phenomenon.

[0025] Further, a sunken step is arranged on the top of the main machine outside the opening periphery; the air inlet seat further comprises a top cover, the side wall of the seat body is provided with the air inlet, the size of the top cover is greater than that of the seat body, the top cover is arranged on the top of the seat body, and the outer extension edge of the top cover is formed at the peripheral edge of the top cover outside the seat body. The seat body is retracted into the inner cavity of the main machine, and the outer extension edge abuts against the sunken step.

[0026] The structure realizes embedded positioning by arranging the sunken step on the top of the main machine and cooperating with the outer extension edge of the top cover of the air inlet seat, thereby effectively improving the sealing performance of the air inlet seat in the storage state. At the same time, the outer extension edge and the sunken step constitute an air inlet seat limiting structure without additional buckles, thereby improving the reliability and service life of the whole machine.

[0027] Further, the top of the air inlet seat or the main machine is provided with a hooking device.

[0028] The top of the air inlet seat or the main machine is provided with the hooking device, so that the whole machine can be flexibly hung on the door back, clothes rod, wall hook or other narrow or space-limited places during use, thereby greatly improving the application scenarios and space utilization rate of the clothes drying equipment and meeting the diversified use requirements of users.

[0029] Further, the hooking device comprises a hook body part and a rod body part, and the hook body part and the rod body part are connected; the top of the air inlet seat is provided with a rod body accommodating groove, the top of the main machine is provided with a hook body accommodating groove, and the rod body part is rotatably connected in the rod body accommodating groove; the air inlet seat is retracted into the inner cavity of the main machine, the rod body accommodating groove and the hook body accommodating groove are communicated, the hooking device is rotated, the rod body part is arranged in the rod body accommodating groove, and the hook body part is arranged in the hook body accommodating groove.

[0030] The rod body accommodating groove and the hook body accommodating groove are arranged on the top of the air inlet seat and the main machine respectively, and the hooking device is folded or unfolded in the groove in a rotating manner. The structure realizes hidden storage and one-key unfolding of the hooking device. When stored, the hooking device is completely hidden in the machine body, which not only maintains the simple and beautiful appearance, but also avoids the risk of being scratched due to exposure of the hooking device. When unfolded, the rod body part and the hook body part can be accurately positioned outside the groove by only rotating, which is convenient for hooking the clothes drying machine.

[0031] Further, a clothes hanging rod for hanging clothes, a humidity sensor and a temperature sensor are further included, the clothes hanging rod is arranged on the main machine and below the air outlet, the size of the drying device is smaller than the size of the inner cavity of the air inlet seat and is arranged below the opening of the main machine, the drying device includes a fan and a heating assembly, and the fan and the heating assembly are electrically connected with the circuit board respectively, the air inlet seat extends out of the inner cavity of the main machine through the opening, and the hollow cavity of the air inlet seat forms an air passage, the humidity sensor and the temperature sensor are arranged in the inner cavity of the main machine and above the air outlet, the humidity sensor and the temperature sensor are electrically connected with the circuit board respectively, the detection surfaces of the humidity sensor and the temperature sensor face the air outlet, the humidity sensor and the temperature sensor feed real-time humidity and temperature signals to the circuit board respectively, and the circuit board dynamically adjusts the rotating speed of the fan and the power of the heating assembly based on the signals. When the air inlet seat is retracted into the inner cavity of the main machine through the opening, the drying device is automatically slid into the hollow cavity of the air inlet seat and is stored through the open bottom of the air inlet seat.

[0032] When the air inlet seat extends out of the main machine, the fan and the heating assembly are opposite to the open bottom of the hollow cavity, an efficient straight air passage is formed, and an efficient drying path is realized, in which the heated air flows through the clothes and is uniformly discharged from the air outlet.

[0033] In the storage state in which the air inlet seat is retracted into the inner cavity of the main machine, the drying device can be slid into the cavity of the air inlet seat as a whole, the thickness and volume of the whole machine are effectively reduced, and the storage convenience is improved.

[0034] The clothes hanging rod is arranged directly below the air outlet, which not only provides structural support for directly hanging clothes to be dried for the user, but also ensures that the air flow directly reaches the surface of the clothes, avoids waste of heat and wind power, and further improves the drying efficiency.

[0035] By arranging the temperature sensor and the humidity sensor, the environmental data in the drying cavity are collected in real time, and signals are fed back to the circuit board, so that the system can automatically adjust the rotating speed of the fan and the heating power according to the current humidity and temperature, and intelligent control is realized. This dynamic adjustment not only improves the drying efficiency, but also prevents problems such as overheating, over-drying, excessive energy consumption and the like, and significantly improves the safety, energy saving and clothes care effect of the equipment.

[0036] The beneficial effects of the present application are as follows:

[0037] In the present application, the left box part and the right box part are designed to be rotatable and expandable / foldable, combined with the linkage sliding out and retracting mechanism of the air inlet seat, through structures such as sliding rods, gears and flexible linkage belts, an air inlet passage is automatically formed when the main machine is expanded, and the main machine is compactly stored when it is folded, so that the volume of the equipment is greatly reduced, the equipment is convenient to hang and use and is convenient to store daily, the equipment does not occupy the living space, and is suitable for small household users.

[0038] The air inlet seat is equipped with a triple composite filtering system and an arc-shaped flow guide rib structure, which effectively intercepts large-particle impurities, small suspended particles and microorganisms, ensures the cleanliness of the air sent into the main machine, improves the stability of the air path, reduces airflow noise, prevents dust from entering the main machine and damaging electrical components, and improves product durability and clothing hygiene protection.

[0039] The main machine is provided with humidity and temperature sensors, which detect the environment data inside the drying bag facing the air outlet, and intelligently control the fan speed and heating power through the circuit board in real time, dynamically adapt to the dry and wet state of the clothes, realize intelligent drying with "fast and energy-saving", avoid overheating and over-drying, prolong the service life of the clothes, and reduce energy consumption.

[0040] When the air inlet seat extends out of the main machine cavity along the opening direction, the abutting portion slides to the blocking portion position, and mechanical contact forms clear physical limiting, which limits the maximum extension range of the air inlet seat. At this time, the abutting portion simultaneously presses the touch rod of the micro switch, the micro switch sends a signal feedback to the circuit board, and the circuit board confirms that the air inlet seat has been completely unfolded, allowing the drying device to start working, thereby realizing electrical position confirmation and safety interlocking.

[0041] In order to prevent the air inlet seat from sliding down due to its own weight or vibration during use, a spring-driven blocking block locking mechanism is designed. The spring makes the pressing portion of the blocking block elastically abut on the guide slope of the limiting step through the elastic force, generating a locking torque, mechanically locking the air inlet seat, and preventing it from sliding down due to gravity. When the air inlet seat is forcibly moved downward by external force (for example, the user forcibly rotates the left box part or the right box part, causing the air inlet seat to slide down), the pressing portion can smoothly slide along the guide slope, extruding the spring and driving the blocking block to release the lock, so that the air inlet seat automatically retracts to the predetermined position in the main machine 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 equipment due to misoperation, thereby improving the safety and durability of the whole machine.

[0072] The use method of the clothes dryer is as follows: when a user needs to use the clothes dryer for drying, first, the user rotates the hooking device 10 upward to unfold, so that the hook body 101 is flipped from the hook body accommodating groove 16 to a hanging position. Then, the user hangs the hook body 101 on a support such as a wardrobe rod, a hook or a door back rod, to ensure that the main machine 1 is stably hung.

[0073] Then, the user holds the left box 3 or the right box 4 to open, and drives the left box 3 and the right box 4 to rotate and expand synchronously through the gear transmission, so that the left slide rod 311 and the right slide rod 411 jointly drive the air inlet seat 5 to extend out of the inner cavity of the main machine 1 along the opening 11 direction until the abutting portion 55 contacts the blocking portion 13, thereby limiting the maximum extension position of the air inlet seat 5 through the contact limiting mode, and at the same time, the abutting portion 55 contacts the touch rod 71 of the micro switch 7, the micro switch 7 feeds back a signal to the circuit board 30, the circuit board 30 turns on the power supply of the drying device 2, and the elastic force of the spring 58 drives the blocking block 9 to move outward until the pressing portion 91 of the blocking block 9 elastically abuts on the guide inclined surface 141 of the limiting step 14, thereby preventing the air inlet seat 5 from sliding down due to gravity and ensuring that it remains in a stable expanded state during operation.

[0074] Subsequently, the user hangs the drying bag on the left box 3 and the right box 4 to form a closed or semi-closed space, puts the clothes to be dried into the drying bag and hooks them on the clothes hook 20, so that the clothes to be dried are located directly below the air outlet 12. The user starts the drying device 2 through the control panel, and the fan 21 starts to operate at high speed to suck external air into the air inlet 51 through negative pressure. The air first passes through the guide of the arc-shaped flow guide rib 511 to stabilize the airflow direction, reduce turbulence and noise, and improve air flow efficiency.

[0075] Then, the air enters the dust filter screen assembly 6 and is filtered in sequence: the first layer of coarse filter layer 611 intercepts large-particle impurities such as hair and fibers; the second layer of electret static layer 612 captures fine suspended particles through electrostatic adsorption; and the third layer of micro filter layer 613 is a microporous PTFE membrane with extremely fine pores, which effectively blocks dust and microorganisms to ensure that the air sent into the interior is clean and pollution-free.

[0076] The filtered clean air enters the heating assembly 22 area through the air duct, is heated to form constant-temperature hot air, and is stably blown into the drying bag from the air outlet 12 at the bottom of the main machine 1. The hot air circulates in the drying bag, focusing on the clothes around to accelerate the evaporation of moisture on the surface and inside of the clothes. The drying bag plays a role in wind focusing and dust isolation, while suppressing heat loss. The temperature sensor and the humidity sensor monitor the bag environment in real time, dynamically feed back the data to the circuit board 30, and the circuit board 30 adjusts the fan 21 speed and heating power according to the data to achieve energy-saving and efficient intelligent drying.

[0077] After the drying process is completed, the user first turns off the power of the clothes dryer, takes out the clothes, and then takes down the drying bag and stores it. Next, the user presses the pressing portion 91 of the blocking block 9 to drive the blocking block 9 to rebound inward, so that it is separated from the guide inclined surface 141 of the limiting step 14, and then pushes the air inlet seat 5 to slide into the inner cavity of the main machine 1 along the opening 11 direction, which drives the left box 3 and the right box 4 to rotate and close to the two sides of the main machine 1 through the original slide rod and gear transmission mechanism linkage, and completes the closure of the shell.

[0078] Finally, the user reversely rotates the hooking device 10, so that the hook body part 101 is re-stored in the hook body accommodating groove 16, and the rod body part 102 is re-stored in the rod body accommodating groove 59, and the whole clothes dryer returns to the compact storage state, and is conveniently put back into the storage space, and the whole use process is completed.

[0079] The micro switch 7 is installed inside the sealed box body 8, and the sealed box body 8 is provided with a gas-permeable micro-pore 81 with a PTFE film 82 inside, which can effectively isolate moisture and water mist, prevent the switch from being damp and oxidized, and prevent the contact from malfunctioning. At the same time, it can also block the fiber dust generated during the drying process of the clothes from entering, so as to avoid the switch from being stuck or mis-triggered.

[0080] The sealed box body 8 is also provided with a drainage groove and a one-way flow guide valve 85, so that even if water vapor condenses into water droplets, it can be smoothly drained, keeping the working area of the switch dry and clean.

[0081] In addition, this closed structure can also concentrate the electrical elements, build a safer and more stable electrical control environment, prevent the spread of electric arc or failure, and prolong the service life of the micro switch 7 and related electrical elements, and greatly improve the reliability and safety of the clothes dryer in a humid and high-temperature environment.

[0082] The benefits of the outside air being guided by the arc-shaped guide ribs and filtered by the dustproof filter screen assembly 6 before entering the inner cavity of the clothes dryer for heating: the outside air is guided by the arc-shaped guide ribs before entering the clothes dryer, effectively optimizing the airflow direction, reducing turbulence and noise, and improving the air intake efficiency. Then, it is filtered by the dustproof filter screen assembly 6, which can effectively block dust, lint and fiber particles in the air, preventing impurities from entering the inside of the clothes dryer. This process not only ensures that the air entering the drying system is cleaner, which helps to maintain the long-term cleanliness of the heating elements and the air duct, reduces the maintenance frequency, but also improves the heat exchange efficiency and the drying performance of the whole machine, and prolongs the service life of the internal key components.

[0083] The benefits of the gear meshing structure combined with the flexible linkage belt 54: the left slide rod 311 and the right slide rod 411 achieve efficient synchronous linkage, ensuring that the left and right sides can move in balance and coordination at the same time when the user rotates the left box part 3 or the right box part 4 to expand or fold, thereby avoiding the tilting, jamming or deviation of the air inlet seat 5 caused by unilateral force. This structure ensures the linear movement of the air inlet seat 5, enhances the convenience and durability of the clothes dryer, and reduces the risk of wear and failure caused by structural imbalance.

[0084] In other embodiments, the flexible linkage belt 54 comprises an aramid fiber braid for bearing tensile load and maintaining deformation stability, and a hot-pressed thermoplastic polyurethane coating layer for providing flexibility, slip resistance and wear resistance, the thermoplastic polyurethane coating layer covering the aramid fiber braid; the outer surface of the thermoplastic polyurethane coating layer is provided with anti-slip ribs to prevent slipping and deviation, the thermoplastic polyurethane coating layer is integrally formed with the aramid fiber braid through a hot-pressing co-extrusion process, the adhesion between the thermoplastic polyurethane coating layer and the aramid fiber braid is not less than 1.5 N / mm; the aramid fiber braid is a multi-strand staggered braid structure, the width of the aramid fiber braid is 8-15 mm, and the thickness of the aramid fiber braid is 0.2-0.6 mm; the end of the flexible linkage belt 54 is provided with a metal reinforced chuck for connecting a left slide rod or a right slide rod, the metal reinforced chuck is made of stainless steel or aluminum alloy material, and the metal reinforced chuck is fixedly connected with the end of the flexible linkage belt 54 in a punching and riveting manner.

[0085] The flexible linkage belt 54 structure covers the aramid fiber braid with a thermoplastic polyurethane material, not only achieving high-strength bearing and excellent deformation stability, but also taking into account good flexibility and wear resistance, effectively improving the reliability and service life of the linkage system. The aramid fiber braid adopts a multi-strand staggered braid structure, which not only maintains a soft feel but also enhances the overall tensile and tear resistance, can adapt to high-frequency repeated loads in multiple stretching and contracting actions of the clothes dryer, and is not prone to deformation or breakage. The thermoplastic polyurethane coating layer is integrally formed with the aramid braid through a hot-pressing co-extrusion process, ensuring tight bonding between the materials and achieving an adhesion of more than 1.5 N / mm, which can effectively prevent peeling or delamination between the coating layer and the braid due to long-term use. At the same time, the anti-slip rib structure on the outer surface can enhance the friction between the flexible linkage belt 54 and the pulley or the sliding groove, avoiding slipping, deviation and other phenomena during transmission, and ensuring the synchronous unfolding and folding actions of the left and right slide rods. In addition, the metal reinforced chuck is provided at both ends of the flexible linkage belt 54, made of stainless steel or aluminum alloy material, and fixed with the belt body through punching and riveting, which not only improves the structural strength of the connection part but also ensures firm 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 structure combines high-strength materials and anti-slip technology design, not only meeting the use requirements of the clothes dryer under high humidity, high temperature and multiple stretching conditions, but also having good processing formability and assembly stability, which is a key component for improving the performance of the linkage transmission system and the reliability of the entire machine.
