Description

Technical Field

[0001] This application relates to the field of air handling equipment technology, and in particular to a dehumidifier with a replaceable rotor. Background Technology

[0002] Rotary dehumidifiers are commonly used air humidity control devices, widely applied in homes, industries, and commerce. A typical rotary dehumidifier includes a frame, an air duct within the frame, a rotor within the air duct, a drive mechanism to rotate the rotor, and other components for air handling (such as a fan, heater, and heat exchanger). Air flows through the rotor under the action of the fan, and the moisture-absorbing material on the rotor absorbs moisture from the air, thus achieving dehumidification.

[0003] However, existing rotary dehumidifiers are prone to the following problems during long-term use: First, since rotary dehumidifiers typically operate in an air environment, the air inevitably contains dust, impurities, and other particulate matter. These particles enter the dehumidifier with the air and gradually accumulate in the honeycomb channels of the rotor, causing blockage. This blockage reduces the rotor's moisture absorption efficiency, directly leading to a decline in dehumidification performance. Second, during operation, rotary dehumidifiers require heating and regeneration of the rotor to release adsorbed moisture. Prolonged high-temperature baking, especially when temperature control is inaccurate, can easily cause deformation of the rotor material, such as deformation of the honeycomb channels or a reduction in the size of the openings. This rotor deformation also reduces airflow efficiency and moisture absorption area, further affecting the dehumidification effect.

[0004] Traditionally, if the dehumidifier rotor becomes clogged or deformed, the entire unit is scrapped. Replacing the rotor is extremely complicated. In existing dehumidifier structures, the rotor is usually fixed inside the frame, making replacement very inconvenient. Users need to use screwdrivers and other tools to disassemble the dehumidifier's outer casing to access the internal space where the rotor is located. Furthermore, because the rotor is usually tightly connected to other functional modules of the dehumidifier (such as the fan, heater, and air ducts), these related components often need to be removed before removing the rotor to make room for its removal. For example, it may be necessary to disassemble the processing air generation module and the regeneration air generation module connected to the rotor module.

[0005] Because the disassembly process is complicated, involving the removal and assembly of multiple components, and requires certain professional knowledge and skills, the replacement of the impeller usually needs to be performed by professional repair personnel. Ordinary users cannot perform it themselves, resulting in high maintenance costs and a long time consumption. Utility Model Content

[0006] To address the aforementioned issues, this application provides a dehumidifier with a replaceable rotor, which enables convenient replacement and maintenance of the rotor through a pull-out rotor module design.

[0007] To achieve the above objectives, this application designs a dehumidifier with a replaceable rotor. The dehumidifier includes a frame and a rotor, as well as a shaft assembly and a mounting bracket. The rotor is rotatably mounted on the mounting bracket via the shaft assembly. The rotor, shaft assembly, and mounting bracket form a rotor module. The frame is provided with a pull-out port suitable for inserting and removing the rotor module. The shaft assembly is equipped with a self-locking mechanism, which has a locked state when not subjected to external force and an unlocked state after being operated. When the self-locking mechanism is in the locked state, it locks the rotor onto the shaft assembly. When the self-locking mechanism is in the unlocked state, the rotor can be removed from the shaft assembly.

[0008] A further embodiment includes a self-locking mechanism comprising two snap fasteners slidably disposed on the rotating shaft assembly and a compression spring disposed between the two snap fasteners; when the two snap fasteners are not subjected to external force, the self-locking mechanism is in the locked state, and the compression spring drives the two snap fasteners to abut against the inner peripheral wall of the rotating wheel to lock the rotating wheel to the rotating shaft assembly; when the two snap fasteners are operated and move closer to each other, the self-locking mechanism is in the unlocked state.

[0009] A further embodiment includes a support arm on the mounting bracket, and a rotating shaft assembly comprising a central fixing sleeve and a bearing fixed within the central fixing sleeve. Two spring clips are slidably disposed at the end of the central fixing sleeve away from the support arm, and a compression spring is housed within the central fixing sleeve. A support shaft, coaxially arranged with the central fixing sleeve, is provided at the distal end of the support arm. The support shaft is connected and fixed to the inner ring of the bearing, thereby enabling the central fixing sleeve to rotate relative to the support arm.

[0010] A further embodiment is that each of the two spring clips is provided with a locking part on the opposite side, the locking part protruding from the outer peripheral surface of the central fixing sleeve and pressing against the inner peripheral wall of the rotating wheel.

[0011] A further embodiment is that the mounting frame is provided with a positioning shaft extending along the rotation axis of the rotating wheel, and an elastic positioning structure is provided in the pull-out opening corresponding to the position of the positioning shaft; when the rotating wheel module is inserted into the pull-out opening, the positioning shaft of the mounting frame and the elastic positioning structure are engaged.

[0012] A further embodiment is that a groove is provided inside the pull-out opening along the pull-out direction parallel to the wheel module, and the support arm slides in cooperation with the groove; the elastic positioning structure includes two elastic clamping arms disposed opposite to each other at the bottom of the groove, and the positioning shaft is elastically clamped by the two elastic clamping arms.

[0013] A further embodiment is that each of the two elastic clamping arms includes a guide section, an arc-shaped positioning section, and a straight section arranged sequentially along the insertion direction of the rotary module. The two guide sections form a guide opening with a gradually widening opening. The two arc-shaped positioning sections form a clamping groove for elastically clamping the positioning shaft. The other end of the two straight sections is connected to the groove wall of the sliding groove. A limiting protrusion extending along the length direction of the straight section is provided between the two straight sections, and one end of the limiting protrusion abuts against the outer peripheral surface of the positioning shaft.

[0014] A further embodiment is that the opposite walls of the slide are respectively provided with limiting blocks to form limiting grooves in the slide, and the two sides of the support arm are respectively inserted into the limiting grooves, with the limiting blocks abutting against the side of the support arm facing the turntable.

[0015] A further option is to provide a handle on the side of the mounting bracket away from the support arm; or, the mounting bracket has a hollow structure, and the hollow structure forms a pull-out position suitable for hand gripping on the side away from the support arm.

[0016] A further embodiment includes a circular frame on the mounting bracket for accommodating the rotating wheel, with the distal end of the support arm extending to the axis of the circular frame. The dehumidifier also includes a drive assembly for driving the rotating wheel to rotate. The drive assembly includes a drive motor fixed to the frame, a drive wheel rotatably mounted on the frame, and a driven wheel rotatably mounted on the mounting bracket or frame. The output shaft of the drive motor is connected to the drive wheel. A gear ring is fitted around the outer circumference of the rotating wheel. A first notch and a second notch are provided on the outer circumferential surface of the circular frame. The drive wheel extends into the first notch and meshes with the gear ring, and the driven wheel extends into the second notch and meshes with the gear ring.

[0017] The dehumidifier with replaceable rotor designed in this application integrates the rotor, shaft assembly, and mounting bracket into a pull-out rotor module that can be installed along the frame. Unlike designs with fixed rotors, this allows for convenient removal and installation of the rotor. This eliminates the need for cumbersome disassembly of the dehumidifier frame and other internal components during necessary maintenance, greatly simplifying rotor replacement and maintenance. Even users without specialized tools and skills can easily complete the process. Furthermore, this ease of maintenance indirectly extends the dehumidifier's lifespan and reduces the likelihood of the entire unit being scrapped due to minor malfunctions. Therefore, this design not only improves dehumidifier maintenance efficiency but also lowers the maintenance threshold, ultimately providing users with a more economical, convenient, and sustainable dehumidification experience.

[0030] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0031] This application designs a dehumidifier with a replaceable rotor, aiming to facilitate convenient rotor replacement and maintenance. For example... Figures 1 to 11 As shown, the dehumidifier mainly includes a frame 10, a rotor 20, a shaft assembly 30, and a mounting bracket 40. The rotor 20 is rotatably mounted on the mounting bracket 40 via the shaft assembly 30. The rotor 20, shaft assembly 30, and mounting bracket 40 form a single, pull-out rotor module 100. This rotor module 100 is not directly connected to other functional components commonly found on dehumidifiers, such as dehumidification, heat exchange, airflow drive, or heating. To accommodate this modular design, the frame 10 is equipped with a pull-out opening 11 whose size matches the overall shape of the rotor module 100. Users can easily remove or install the rotor module 100 through this pull-out opening 11 without disassembling any other parts of the dehumidifier, thus enabling necessary maintenance operations.

[0032] The rotating shaft assembly 30 is equipped with a self-locking mechanism 50, which has a locked state when no external force is applied and an unlocked state after being operated. The self-locking mechanism 50 can switch between the locked and unlocked states. When the self-locking mechanism 50 is in the locked state, it locks the rotating wheel 20 onto the rotating shaft assembly 30, effectively preventing the rotating wheel 20 from loosening or falling off during use and ensuring that it can rotate stably with the rotating shaft assembly 30. When the self-locking mechanism 50 is in the unlocked state, the rotating wheel 20 can be removed from the rotating shaft assembly 30. That is, the user can switch the self-locking mechanism 50 to the unlocked state through specific operations, such as pressing or sliding. At this time, the rotating wheel 20 can be easily removed from the rotating shaft assembly 30 for replacement. After the replacement is completed, whether installing a new rotary wheel 20 or the original rotary wheel 20 after maintenance, simply install it onto the rotary shaft assembly 30 and relock it through the self-locking mechanism 50, and then push the entire rotary wheel module 100 back into the frame 10 along the pull-out port 11. The entire operation process is simple and quick, significantly reducing the difficulty of maintenance and avoiding the need to disassemble the frame 10 or other complex internal components.

[0033] In this embodiment, as Figure 4 As shown, to ensure the stability of the rotary module 100 within the frame 10, two elastic buckles 48 are provided on opposite sides of the mounting bracket 40, and corresponding locking holes matching the elastic buckles 48 are provided in the pull-out opening 11 of the frame 10. When the rotary module 100 is inserted into the frame 10 along the pull-out opening 11, the elastic buckles 48 automatically engage with the locking holes, thereby firmly fixing the rotary module 100 in the predetermined position. This effectively prevents the rotary module 100 from accidentally sliding out of the pull-out opening 11 due to equipment vibration or accidental tilting during use, ensuring reliable operation of the equipment. When it is necessary to remove the rotary module 100, the user only needs to pull the mounting bracket 40 outward with a little force to allow the elastic buckles 48 to overcome their engaging force and disengage from the locking holes, making it easy to remove the rotary module 100 from the frame 10. The operation is simple and intuitive.

[0034] In some embodiments, such as Figure 3 , Figure 8 , Figure 10As shown, the self-locking mechanism 50 includes two spring clips 51 slidably disposed on the rotating shaft assembly 30 and a compression spring 52 disposed between the two spring clips 51. When the two spring clips 51 are not subjected to external force, the self-locking mechanism 50 is in a locked state. The compression spring 52 drives the two spring clips 51 to abut against the inner peripheral wall of the rotating wheel 20 to lock the rotating wheel 20 to the rotating shaft assembly 30. In this way, the compression spring 52 always maintains an outward pushing force on the two spring clips 51, so that the outer surface of the spring clips 51 can closely fit the inner peripheral wall of the rotating wheel 20. The spring clips 51 securely lock the rotating wheel 20 to the rotating shaft assembly 30 through the elastic force of the compression spring 52, ensuring that the rotating wheel 20 will not spin freely or deviate when rotating. When the two spring clips 51 are operated and brought together, the self-locking mechanism is in the unlocked state. That is, after the rotating wheel module 100 is removed, for example, by simultaneously pressing the two spring clips 51 inward, the two spring clips 51 overcome the elastic force of the compression spring 52 and move closer to each other, thereby releasing the pressure on the inner peripheral wall of the rotating wheel 20. At this time, the rotating wheel 20 can be easily removed from the rotating shaft assembly 30. This unlocking method, which can be operated with one hand, improves the convenience of maintenance.

[0035] For ease of operation, such as Figure 7 , Figure 8 , Figure 10 As shown, the two spring clips 51 are provided with pressing parts 53 that are suitable for human hand operation. The protruding pressing parts 53 are directly exposed on the outside of the spring clips 51, providing users with a clearly visible and easily accessible operating area. The protruding shape can provide a better finger contact point and friction, making it easier for users to apply pressing force to unlock.

[0036] To improve the stability of locking the spool 20, on the one hand, such as Figure 8 As shown, the surface of the protrusion 511 on the spring clip 51 that abuts against the rotating wheel 20 is designed as an arc surface that matches the inner circumferential wall of the rotating wheel 20. The arc surface provides a larger actual contact area, thereby generating greater friction under the same spring pressure. Simultaneously, to enhance the friction effect, an anti-slip structure is also provided on the arc surface to increase the friction between the arc surface and the rotating wheel. In this embodiment, the anti-slip structure can be used alone or in combination, including various forms such as protrusions, grooves, raised strips, and anti-slip textures. For example, in a specific example of this embodiment, fine protrusions can be evenly arranged on the arc surface. These protrusions can embed into the tiny unevenness of the inner wall of the rotating wheel when locked, further increasing the coefficient of friction and ensuring the stability of the lock.

[0037] On the other hand, such as Figure 8 , Figure 10As shown, each of the two spring clips 51 has a protrusion 511 on its opposite side. When the self-locking mechanism 50 is in a locked state without external force, these two protrusions 511 protrude outward along the axial direction of the roller 20, and their positions are designed to be located on the outer side of the axial end face of the roller 20, which can effectively restrict the movement of the roller 20 along the axial direction of the shaft assembly 30. When the roller 20 undergoes unexpected axial displacement during the operation of the dehumidifier, it will be blocked by these two protrusions 511, thus ensuring that the roller 20 always remains in the predetermined axial position and will not move. When the user needs to replace the roller 20 and operates the spring clips 51 to move closer to each other, the spring clips 51 move radially inward, and the protrusions 511 on their backs also move inward, disengaging from the axial end face of the roller 20 or creating a sufficient gap. In this way, while releasing the radial lock, the restriction on the axial position of the roller 20 is also released, and the user can easily remove the roller 20 axially from the shaft assembly 30.

[0038] In some embodiments, such as Figure 2 , Figure 7 , Figure 8 , Figure 10 As shown, the mounting bracket 40 is provided with a support arm 41, which provides a reliable fixed base for the rotating shaft assembly 30. The rotating shaft assembly 30 includes a central fixing sleeve 31 and a bearing 32 fixed inside the central fixing sleeve 31. The central fixing sleeve 31 is designed as a hollow structure, which is used to house the bearing 32 and the compression spring 52. Two spring clips 51 are slidably set at the end of the central fixing sleeve 31 away from the support arm 41, providing sufficient operating space for the user to operate the spring clips 51 to unlock the rotating wheel. The compression spring 52 is housed inside the central fixing sleeve 31, which can reduce the impact of dust, moisture and other factors on its performance. The far end of the support arm 41 is provided with a support shaft 42 arranged coaxially with the central fixing sleeve 31. The support shaft 42 is connected and fixed to the inner ring of the bearing 32, so that the central fixing sleeve 31 can rotate relative to the support arm 41. The structure is simple and easy to assemble.

[0039] Specifically, such as Figure 10 , Figure 11As shown, an annular baffle 311 is provided inside the central fixing sleeve 31. The outer ring of the bearing 32 is interference-fitted with the inner circumferential wall of the central fixing sleeve 31. One end of the bearing 32 abuts against the side of the annular baffle 311 facing the support arm 41. An annular protrusion 43 is provided on the support arm 41, surrounding the outer circumference of the support shaft 42. One end of the annular protrusion 43 extends into the central fixing sleeve 31 and abuts against the other end of the bearing 32. A central screw 44 is connected to one end of the support shaft 42. The nut of the central screw 44 is pressed against the side of the annular baffle 311 away from the bearing 32. With this structural design, the annular baffle 311 and the annular protrusion 43 on the support arm 41 are located on both sides of the bearing 32, forming a bidirectional axial constraint on the bearing 32. This effectively prevents any form of axial movement or loosening of the bearing 32 inside the central fixing sleeve 31, ensuring its positional stability under operation or other complex working conditions. In addition, the axial fixing force on the bearing 32 is further enhanced by the tightening of the annular baffle 311 by the central screw 44 and its nut, which ensures the smooth and reliable operation of the impeller 20.

[0040] Furthermore, such as Figure 11 As shown, the inner circumferential wall of the central fixing sleeve 31 is provided with multiple protrusions 312 spaced apart. The multiple protrusions 312 form a fixing cavity for receiving the bearing 32. The outer ring of the bearing 32 abuts against each protrusion 312. The end of the protrusion 312 is provided with a guide slope 313 to facilitate the insertion of the bearing 32 into the assembly fixing cavity. The protrusions 312 facilitate the assembly of the bearing 32 and also facilitate the removal, replacement and maintenance of the bearing 32; while the guide slope 313 can guide the outer ring of the bearing 32 to slide smoothly into the fixing cavity, reducing installation resistance and improving assembly efficiency.

[0041] In some embodiments, such as Figure 8 , Figure 10 As shown, a guide groove 314 is provided on the outer peripheral wall of the central fixing sleeve 31, penetrating both radial sides of the central fixing sleeve 31. The spring buckle 51 is slidably disposed in the guide groove 314. The guide groove 314 limits the sliding direction of the spring buckle 51, so that it can only move in the radial direction of the central fixing sleeve 31, avoiding the spring buckle 51 from twisting or jamming during unlocking / locking, and ensuring the reliability and smooth operation of the self-locking mechanism 50. In addition, when the compression spring 52 is housed in the central fixing sleeve 31, mounting holes are recessed on the inner surfaces of the two spring buckles 51 facing each other. The two ends of the compression spring 52 are fitted into the corresponding mounting holes to improve the stability of the compression spring 52 when it is compressed and restored.

[0042] In some embodiments, such as Figure 7 , Figure 8 , Figure 10As shown, one end cap of the central fixing sleeve 31 is provided with an end cap 33 to prevent the spring clips 51 from dislodging from the central fixing sleeve 31. The end cap 33 has a limiting groove 331 corresponding to the position of each spring clip 51, which communicates with the guide groove 314. The pressing part 53 of the spring clip 51 extends out from the corresponding limiting groove 331. The limiting groove 331 is used to limit the movement range of the pressing part 53. In this embodiment, the end cap 33 serves as a closed structure at the axial end of the central fixing sleeve 31. Specifically, it can be locked onto the central fixing sleeve 31 by two screws. The main function of the end cap 33 is to physically prevent the spring clips 51 from moving along the axial direction of the central fixing sleeve 31 and dislodging from the central fixing sleeve 31. At the same time, the limiting groove 331 of the end cap 33 limits the sliding stroke of the pressing part 53 on the spring clip 51, which can prevent the user from excessively pressing the pressing part 53 during operation, avoid blindly applying force, and thus prevent the compression spring 52 from being over-compressed, resulting in damage or shortened life.

[0043] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the mounting bracket 40 is provided with a positioning shaft 45 extending along the rotation axis of the rotating wheel 20, and an elastic positioning structure 60 is provided in the pull-out port 11 corresponding to the position of the positioning shaft 45. When the rotating wheel module 100 is inserted into the pull-out port 11, the positioning shaft 45 of the mounting bracket 40 and the elastic positioning structure 60 are positioned and engaged. The elastic positioning structure 60 can be a claw, an elastic sheet, or other component with elastic deformation capability made of elastic material. When the rotating wheel module 100 is slidably inserted into the pull-out port 11, the positioning shaft 45 will gradually approach the elastic positioning structure 60 and will eventually be firmly clamped or locked by the elastic positioning structure 60, so as to provide a stable rotation axis center for the smooth rotation of the rotating wheel 20, and reduce the performance degradation that may be caused by slight vibration or positional displacement.

[0044] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 , Figure 6As shown, a groove 12 is provided inside the pull-out opening 11 along the pull-out direction parallel to the rotating wheel module 100. The support arm 41 slides in conjunction with the groove 12. The groove 12 provides precise guidance for the insertion and removal of the rotating wheel module 100, ensuring the stability and smoothness of the rotating wheel module 100 during movement. Meanwhile, the elastic positioning structure 60 includes two elastic clamping arms 61 positioned opposite each other at the bottom of the groove 12. The positioning shaft 45 is elastically clamped by the two elastic clamping arms 61. In this embodiment, the two elastic clamping arms 61 are made of elastic material and have a certain opening and closing capacity. When the positioning shaft 45 on the mounting bracket 40 is inserted between the two elastic clamping arms 61 as the rotary module 100 is inserted, the elastic clamping arms 61 will elastically open to both sides. After the positioning shaft 45 is fully in the predetermined position, the elastic clamping arms 61 will hold the positioning shaft 45 by its own elastic restoring force and provide sufficient clamping force to prevent the rotary module 100 from accidentally loosening or slipping out during use. At the same time, it is convenient for the user to apply appropriate pulling force to remove it when needed.

[0045] In a specific example, such as Figure 2 , Figure 5 As shown, each of the two elastic clamping arms 61 includes a guide section 611, an arc-shaped positioning section 612, and a straight section 613 arranged sequentially along the insertion direction of the rotary module 100. The two guide sections 611 form a guide port with a gradually widening opening. Even if the user's insertion angle is slightly off, the positioning shaft 45 will be gradually guided to the correct path by the guide port and smoothly enter the subsequent arc-shaped positioning section 612. The two arc-shaped positioning sections 612 form a clamping groove for elastically clamping the positioning shaft 45. Once the positioning shaft 45 enters the clamping groove formed by the arc-shaped positioning section 612, the two elastic clamping arms 61 will elastically deform and tightly clamp the positioning shaft 45, generating sufficient clamping force. The mounting bracket 40 is relatively fixed to the frame 10 to prevent accidental slippage. The other end of the two straight sections 613 is connected to the groove wall of the slide 12 to provide support. In addition, a limiting protrusion 614 is provided between the two straight sections 613, extending parallel to the length direction of the straight section 613. One end of the limiting protrusion 614 abuts against the outer peripheral surface of the positioning shaft 45 to limit the extreme position of the positioning shaft 45 inserted between the two elastic clamping arms 61, so as to ensure accurate and reliable positioning.

[0046] In some embodiments, such as Figure 4 , Figure 5 , Figure 6As shown, limiting blocks 13 are respectively protruding from the opposite walls of the slide groove 12 to form limiting grooves 331 within the slide groove 12. The two sides of the support arm 41 are respectively inserted into the limiting grooves 331, and the limiting blocks 13 abut against the side of the support arm 41 facing the rotating wheel 20. With this structural design, when the rotating wheel module 100 slides into place along the slide groove 12, the two sides of the support arm 41 in the width direction are respectively inserted into the limiting grooves 331, so that the limiting blocks 13 restrict the axial position of the support arm 41, that is, the entire rotating wheel module 100, making it less prone to shaking.

[0047] The limiting block 13 has a guide slope 131 extending into the limiting groove 331 on its surface relative to the insertion direction of the rotating module 100. A positioning wedge 411 is provided at the distal end of the support arm 41 corresponding to the position of the guide slope 131. The guide slope 131 can guide the positioning wedge 411 of the support arm 41 to smoothly enter the limiting groove 331, reducing assembly resistance and facilitating user operation.

[0048] In some embodiments, the mounting bracket 40 is provided with a handle on the side opposite to the support arm 41 for user convenience; or, as... Figure 1 , Figure 4 , Figure 7 As shown, the mounting bracket 40 has a hollow structure, and a pull-out position 47 suitable for hand gripping is formed on the side of the hollow structure opposite to the support arm 41. The hollow structure directly forms a natural handle, i.e., the pull-out position 47, which allows users to directly grasp the pull-out position 47 for pull-out operation without the need to install additional handles or other auxiliary structures on the mounting bracket 40. At the same time, the use of a hollow mounting bracket 40 can effectively reduce its own weight while ensuring sufficient structural strength, thereby reducing the weight of the entire rotary module 100.

[0049] In some embodiments, such as Figure 3 , Figure 4 , Figure 7 As shown, the mounting bracket 40 is provided with a circular frame 46 for accommodating the rotating wheel 20. This circular frame 46 surrounds the rotating wheel 20, effectively preventing damage to the rotating wheel module 100 from accidental impacts or compression during handling or use. The distal end of the support arm 41 extends to the axis of the circular frame 46. Specifically, as... Figure 7 As shown, the circular frame 46 is provided with multiple reinforcing ribs 463 extending horizontally and / or vertically, and at least a portion of the reinforcing ribs 463 are connected to the support arm 41. These reinforcing ribs 463 can effectively distribute various forces acting on the circular frame 46, improving its bending resistance and impact resistance. In a specific example, such as... Figure 7As shown, the circular frame 46 has two horizontally extending reinforcing ribs and one vertically extending reinforcing rib, which is connected to the support arm 41. In this embodiment, the main frame 10, the circular frame 46, the support arm 41, and the reinforcing rib 463 can be integrally molded, for example, by injection molding. This ensures the stability of the wheel 20 during operation even with a single support arm 41, thanks to the synergistic effect of the multiple reinforcing ribs 463 on the circular frame 46 and the support arm 41.

[0050] Meanwhile, the dehumidifier also includes a drive assembly for driving the rotor 20 to rotate. The drive assembly includes a drive motor fixed to the frame 10, a drive wheel 14 rotatably mounted on the frame 10, and a driven wheel 15 rotatably mounted on the mounting bracket 40 or the frame 10. The output shaft of the drive motor is connected to the drive wheel 14. A gear ring 21 is fitted around the outer circumference of the rotor 20. A first notch 461 and a second notch 462 are provided on the outer circumferential surface of the circular frame 46. The drive wheel 14 extends into the first notch 461 and meshes with the gear ring 21, while the driven wheel 15 extends into the second notch 462 and meshes with the gear ring 21, thereby driving the rotor 20. Simultaneously, extending the drive wheel 14 and the driven wheel 15 into the notches on the outer circumferential surface of the circular frame 46 reduces the overall volume of the drive assembly, making the structure more compact and saving space. Furthermore, the first notch 461 and the second notch 462 are located at the radially opposite ends of the circular frame 46. In specific implementations, such as... Figure 3 As shown, the driven wheel 15 is positioned below the rotating wheel 20 on the left, so that the line connecting the centers of the shafts of the driven wheel 15 and the driving wheel 14 does not pass through the center of the rotating wheel 20. This is equivalent to providing an additional support point for the rotating wheel 20, reducing the load on the driving wheel 14, thereby reducing the risk of the rotating wheel 20 jamming. In addition, the additional support formed by the driven wheel 15 can also effectively prevent the rotating wheel 20 from deforming or tilting, ensuring the normal operation of the drive mechanism.

[0051] like Figure 8 As shown, the wheel module 100 also includes an outer frame 70, which is made of stainless steel, such as 304 stainless steel, and is not prone to rust or corrosion. The outer frame 70 includes a concentrically arranged center seat 71 and a circular sleeve 72, as well as multiple spokes 73 connecting the center seat 71 and the sleeve 72. One end of the wheel 20 is housed in the sleeve 72, forming a protective layer for the wheel 20. Specifically, the sleeve 72 is connected to the gear ring 21 by a first screw 74, and the center seat 71 is connected to the shaft assembly 30 by a second screw 75. The connection is stable and facilitates disassembly for maintenance or replacement when necessary.

[0052] The dehumidifier with replaceable rotor provided in this embodiment integrates the rotor, shaft assembly, and mounting bracket into a pull-out rotor module along the frame. Unlike designs with fixed rotors, this allows for convenient removal and installation of the rotor. This eliminates the need for cumbersome disassembly of the dehumidifier frame and other internal components during necessary maintenance, greatly simplifying rotor replacement and maintenance. Even users without specialized tools and skills can easily complete the process. Furthermore, this ease of maintenance indirectly extends the dehumidifier's lifespan and reduces the likelihood of complete machine failure due to minor malfunctions. Therefore, this design not only improves dehumidifier maintenance efficiency but also lowers the maintenance threshold, ultimately providing users with a more economical, convenient, and sustainable dehumidification experience.
