Description

Technical Field

[0001] The present application relates to the technical field of air treatment equipment, in particular to a dehumidifier with a replaceable rotor. Background Art

[0002] A rotary dehumidifier is a commonly used air humidity adjustment device, which is widely used in households, industries, commerce and other fields. A rotary dehumidifier generally includes a frame, an air duct arranged inside the frame, a rotor arranged inside the air duct, a driving mechanism for driving the rotor to rotate, and other components for processing air (such as a fan, a heater, a heat exchanger, etc.). Air flows through the rotor under the action of the fan, and the moisture-absorbing material on the rotor adsorbs the moisture in the air, thereby achieving dehumidification.

[0003] However, during the long-term use of the existing rotary dehumidifiers, the following problems are likely to occur with their rotors: First, since rotary dehumidifiers usually operate in an air environment, the air inevitably contains particulate matters such as dust and impurities. These particulate matters will enter the interior of the dehumidifier along with the air and gradually deposit in the honeycomb-shaped pores of the rotor, causing the pores to be blocked. The blocked pores will reduce the moisture absorption efficiency of the rotor, directly resulting in a decline in dehumidification performance. Second, during the operation of the rotary dehumidifier, the rotor needs to be heated and regenerated to release the adsorbed moisture. Long-term high-temperature baking, especially when the temperature control is inaccurate, is likely to cause deformation of the rotor material. For example, the honeycomb pores are deformed and the openings become smaller, etc. That is, the deformation of the rotor will also reduce the air circulation efficiency and the moisture absorption area, further affecting the dehumidification effect.

[0004] Once problems such as blockage or deformation occur in the rotor, the traditional approach is generally to scrap the entire machine. If the rotor needs to be replaced, the operation is very cumbersome. In the existing structure of rotary dehumidifiers, the rotor is usually fixedly installed inside the frame, and its replacement operation is extremely inconvenient. When replacing, the user needs to use tools such as a screwdriver to disassemble the outer shell of the dehumidifier to access the internal space where the rotor is located. And since the rotor is usually tightly connected to other functional modules of the dehumidifier (for example, a fan, a heater, an air duct, etc.), before disassembling the rotor, it is often necessary to first remove these related components to make room for the removal of the rotor. For example, it may be necessary to remove the processing air generation module, the regeneration air generation module, etc. connected to the rotor module.

[0005] Due to the cumbersome disassembly steps, involving the disassembly and assembly of multiple components, and requiring certain professional knowledge and operation skills, the replacement of the rotor usually needs to be carried out by professional maintenance personnel. Ordinary users are difficult to complete it by themselves, the maintenance cost is relatively high, and it takes a long time. Summary of the Invention

[0006] To solve the above problems, the present application provides a dehumidifier with a replaceable runner, which realizes the convenient replacement and maintenance of the runner through a design of a retractable runner module.

[0007] To achieve the above object, the dehumidifier with a replaceable runner designed in the present application includes a frame and a runner, and further includes a rotating shaft assembly and a mounting bracket. The runner is rotatably mounted on the mounting bracket through the rotating shaft assembly. The runner, the rotating shaft assembly and the mounting bracket form a runner module. A draw-in port suitable for inserting and withdrawing the runner module is provided on the frame. Wherein, a self-locking mechanism is provided on the rotating shaft assembly. The self-locking mechanism 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, the runner is locked on the rotating shaft assembly. When the self-locking mechanism is in the unlocked state, the runner can be taken out from the rotating shaft assembly.

[0008] A further solution is that the self-locking mechanism includes two spring catches slidably arranged on the rotating shaft assembly and a compression spring arranged between the two spring catches. When the two spring catches are not subjected to external force, the self-locking mechanism is in the locked state. The compression spring drives the two spring catches to abut against the inner peripheral wall of the runner to lock the runner on the rotating shaft assembly. When the two spring catches are operated to approach each other, the self-locking assembly is in the unlocked state.

[0009] A further solution is that a support arm is provided on the mounting bracket. The rotating shaft assembly includes a central fixed sleeve and a bearing fixed in the central fixed sleeve. The two spring catches are slidably arranged at one end of the central fixed sleeve away from the support arm. The compression spring is received in the central fixed sleeve. A support shaft coaxially arranged with the central fixed sleeve is provided at the distal end of the support arm. The support shaft is fixedly connected to the inner ring of the bearing so that the central fixed sleeve can rotate relative to the support arm.

[0010] A further solution is that clamping portions are provided on one side of the two spring catches facing away from each other. The clamping portions protrude from the outer peripheral surface of the central fixed sleeve and abut against the inner peripheral wall of the runner.

[0011] A further solution is that a positioning shaft extending along the rotation axis of the runner is provided on the mounting bracket. An elastic positioning structure is provided at a position corresponding to the positioning shaft in the draw-in port. When the runner module is inserted into the draw-in port, the positioning shaft of the mounting bracket and the elastic positioning structure are positioned and engaged.

[0012] A further solution is that a sliding groove is arranged in the pulling opening along the pulling direction parallel to the rotating wheel module, and the support arm slides in cooperation with the sliding groove; the elastic positioning structure includes two elastic clamping arms relatively arranged at the bottom of the sliding groove, and the positioning shaft is elastically clamped by the two elastic clamping arms.

[0013] A further solution is that the two elastic clamping arms each include a guide section, an arc-shaped positioning section and a straight section which are sequentially arranged along the insertion direction of the rotary module, and the two guide sections relatively form a guide opening with a gradually expanding opening; the two arc-shaped positioning sections form a clamping groove for elastically clamping the positioning shaft; the other ends of the two straight sections are connected to the groove wall of the slide 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 solution is that the groove walls opposite to the slide groove are respectively provided with limit blocks to form a limit groove in the slide groove, the two sides of the support arm are respectively inserted into the limit grooves, and the limit blocks abut against the side of the support arm facing the rotating wheel.

[0015] A further solution is that a handle is provided on the side of the mounting frame away from the support arm; or the mounting frame has a hollow structure, and the hollow structure forms a pull-out position suitable for human hand grasping on the side away from the support arm.

[0016] A further solution is that a circular frame for accommodating a rotating wheel is provided on the mounting frame, and the distal end of the support arm extends to the axis center of the circular frame; the dehumidifier also includes a driving assembly for driving the rotating wheel to rotate, and the driving assembly includes a driving motor fixed to the frame, a driving wheel rotatably mounted on the frame, and a driven wheel rotatably mounted on the mounting frame or the frame, the output shaft of the driving motor is connected to the driving wheel, the outer periphery of the rotating wheel is sleeved with a gear ring, and a first notch and a second notch are provided on the outer periphery of the circular frame, the driving 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 the present application integrates the rotor, shaft assembly and mounting frame into a rotor module that can be pulled out along the frame. Different from the fixed rotor design, the rotor can be easily removed and loaded, so that when necessary maintenance is required, there is no need to tediously disassemble the dehumidifier frame and other internal components, which greatly simplifies the replacement and maintenance operations of the rotor, allowing ordinary users to easily complete them even if they do not have professional tools and skills. At the same time, the convenient maintainability also indirectly extends the service life of the dehumidifier and reduces the scrapping of the entire machine due to minor faults. Therefore, the design of the present application not only improves the maintenance efficiency of the dehumidifier, but also lowers the maintenance threshold, and ultimately brings users a more economical, convenient and sustainable dehumidification experience.

Detailed implementation manners

[0030] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present application, and are not intended to limit the present application.

[0031] The dehumidifier designed in the present application with a replaceable runner aims to achieve the convenient replacement and maintenance of the runner. As Figures 1 to 11 shown, the dehumidifier mainly includes a frame 10, a runner 20, a rotating shaft assembly 30 and a mounting bracket 40. The runner 20 is rotatably mounted on the mounting bracket 40 through the rotating shaft assembly 30. The runner 20, the rotating shaft assembly 30 and the mounting bracket 40 form an integrally drawable runner module 100. This runner module 100 is not directly connected to other common functional components of the dehumidifier such as dehumidification, heat exchange, air flow drive or heating. At the same time, to cooperate with this modular design, a draw opening 11 with a size adapted to the overall shape of the runner module 100 is provided on the frame 10. Without disassembling any other components of the dehumidifier, the user can conveniently take out or install the runner module 100 through this draw opening 11, so as to perform necessary maintenance operations.

[0032] Among them, a self-locking mechanism 50 is provided on the rotating shaft assembly 30. The self-locking mechanism 50 has a locked state when not subjected to external force and an unlocked state after being operated. The self-locking mechanism 50 can switch between the locked state and the unlocked state. When the self-locking mechanism 50 is in the locked state, the rotating wheel 20 is locked to 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 together with the rotating shaft assembly 30. When the self-locking mechanism 50 is in the unlocked state, the rotating wheel 20 can be taken out from the rotating shaft assembly 30. That is, the user can, through specific operations such as pressing and sliding, switch the self-locking mechanism 50 to the unlocked state. At this time, the rotating wheel 20 can be easily taken out from the rotating shaft assembly 30 for replacement. After the replacement is completed, whether it is installing a new rotating wheel 20 or the original rotating wheel 20 after maintenance, it only needs to be installed on the rotating shaft assembly 30 and re-locked through the self-locking mechanism 50, and then the entire rotating wheel module 100 is pushed back into the rack 10 along the draw port 11. The entire operation process is simple and fast, significantly reducing the maintenance difficulty and avoiding the necessity of disassembling the rack 10 or other complex internal components.

[0033] In this embodiment, as Figure 4 shown, to ensure the stability of the rotating wheel module 100 in the rack 10, two elastic buckles 48 are provided on opposite sides of the mounting bracket 40, and corresponding card holes matching the elastic buckles 48 are provided in the draw port 11 of the rack 10. When the rotating wheel module 100 is inserted into the rack 10 along the draw port 11, the elastic buckles 48 will automatically engage with the card holes, thereby firmly fixing the rotating wheel module 100 in a predetermined position and effectively preventing the rotating wheel module 100 from accidentally sliding out of the draw port 11 due to equipment vibration or accidental tilting during use, ensuring the reliable operation of the equipment. When it is necessary to take out the rotating wheel module 100, the user only needs to pull the mounting bracket 40 outward slightly to make the elastic buckles 48 overcome their clamping force and disengage from the card holes, and then the rotating wheel module 100 can be easily taken out from the rack 10, and the operation is simple and intuitive.

[0034] In some embodiments, as Figure 3 、 Figure 8 、 Figure 10As shown, the self-locking mechanism 50 includes two spring catches 51 slidably disposed on the rotating shaft assembly 30 and a compression spring 52 disposed between the two spring catches 51. When no external force acts on the two spring catches 51, the self-locking mechanism 50 is in a locked state. The compression spring 52 drives the two spring catches 51 to abut against the inner peripheral wall of the runner 20 to lock the runner 20 to the rotating shaft assembly 30. In this way, the compression spring 52 always maintains an outward thrust on the two spring catches 51, so that the outer surface of the spring catch 51 can closely fit the inner peripheral wall of the runner 20. The spring catch 51 firmly locks the runner 20 to the rotating shaft assembly 30 through the elastic force of the compression spring 52, ensuring that the runner 20 does not idle or deviate during rotation. When the two spring catches 51 are operated to approach each other, the self-locking assembly is in an unlocked state. That is, after the runner module 100 is taken out, for example, by simultaneously squeezing the two spring catches 51 inward, the two spring catches 51 overcome the elastic force of the compression spring 52 and approach each other, thereby releasing the pressure on the inner peripheral wall of the runner 20. At this time, the runner 20 can be easily removed from the rotating shaft assembly 30. This unlocking method that can be operated with one hand improves the convenience of maintenance.

[0035] For ease of operation, as Figure 7 , Figure 8 , Figure 10 shown, the two spring catches 51 are provided with pressing portions 53 suitable for manual operation. The protruding pressing portions 53 are directly exposed outside the spring catches 51, providing a clearly visible and easily accessible operation area for the user. Moreover, the protruding shape can provide better finger contact points and friction, facilitating the user to apply the unlocking force of pressing.

[0036] To improve the locking stability of the runner 20, on the one hand, as Figure 8 shown, the surface of the convex block 511 on the spring catch 51 for tightly abutting against the runner 20 is designed as an arc surface matching the inner peripheral wall of the runner 20. The arc surface can provide a larger actual contact area, thereby generating greater friction under the same spring pressure. At the same time, to enhance the friction effect, an anti-slip structure is provided on this arc surface to increase the friction between the arc surface and the runner. In this embodiment, the anti-slip structure can be used alone or in combination, including various forms such as bumps, grooves, ribs, and anti-slip patterns. For example, in a specific example of this embodiment, fine bumps can be evenly arranged on the arc surface. These bumps can be embedded in the tiny unevenness of the inner wall of the runner during locking, further increasing the friction coefficient and ensuring the firmness of locking.

[0037] On the other hand, as Figure 8 , Figure 10As shown, bumps 511 are provided on the sides of the two spring catches 51 facing away from each other. When the self-locking mechanism 50 is in the locked state without external force, these two bumps 511 protrude outward along the axial direction of the runner 20, and their positions are designed to be outside the axial end face of the runner 20, which can effectively limit the axial movement of the runner 20 along the shaft assembly 30. When the runner 20 undergoes unexpected axial displacement during the operation of the dehumidifier, it will be blocked by these two bumps 511, ensuring that the runner 20 always remains in the predetermined axial position and does not move axially; when the user needs to replace the runner 20 and operates the spring catches 51 to move closer to each other, while the spring catches 51 move radially inward, the bumps 511 on their backs will also move inward, disengaging from the axial end face of the runner 20 or leaving enough clearance. In this way, while releasing the radial lock, the restriction on the axial position of the runner 20 is also released, and the user can smoothly remove the runner 20 axially from the shaft assembly 30.

[0038] In some embodiments, such as Figure 2 , Figure 7 , Figure 8 , Figure 10 As shown, a support arm 41 is provided on the mounting bracket 40 to provide a reliable fixed base for the shaft assembly 30; the shaft assembly 30 includes a central fixing sleeve 31 and a bearing 32 fixed within the central fixing sleeve 31. The central fixing sleeve 31 is designed as a hollow structure for accommodating the bearing 32 and the compression spring 52 inside; the two spring catches 51 are slidably arranged at one end of the central fixing sleeve 31 away from the support arm 41, providing sufficient operating space for the user to operate the spring catches 51 to unlock the runner. The compression spring 52 is accommodated within the central fixing sleeve 31, which can reduce the influence of dust, moisture, etc. on its performance; a support shaft 42 coaxial with the central fixing sleeve 31 is provided at the distal end of the support arm 41, and the support shaft 42 is connected and fixed to the inner ring of the bearing 32, enabling the central fixing sleeve 31 to rotate relative to the support arm 41, with a simple structure and easy assembly.

[0039] Specifically, such as Figure 10 , Figure 11As shown, an annular baffle 311 is arranged in the center fixing sleeve 31, the outer ring of the bearing 32 is interference fit with the inner circumferential wall of the center fixing sleeve 31, and one end of the bearing 32 abuts against the side of the annular baffle 311 facing the support arm 41; an annular protrusion 43 arranged around the outer circumference of the support shaft 42 is arranged on the support arm 41, one end of the annular protrusion 43 extends into the center fixing sleeve 31 and abuts against the other end of the bearing 32; a center screw 44 is connected to one end of the support shaft 42, and the nut of the center 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 respectively located on both sides of the bearing 32, and together form a bidirectional axial constraint on the bearing 32, so as to effectively prevent any form of axial movement or loosening of the bearing 32 inside the center fixing sleeve 31, and ensure its stable position under operation or other complex working conditions. In addition, the central screw 44 and its nut press the annular baffle 311 , thereby further enhancing the axial fixing force on the bearing 32 , thereby providing a guarantee for the smooth and reliable operation of the runner 20 .

[0040] Further, such as Figure 11 As shown, the inner circumferential wall of the central fixing sleeve 31 is provided with a plurality of convex strips 312 at intervals in the circumferential direction, and the plurality of convex strips 312 surround a fixing cavity for accommodating the bearing 32. The outer ring of the bearing 32 is pressed against each convex strip 312, and the end of the convex strip 312 is provided with a guide slope 313 for facilitating the insertion and assembly of the bearing 32 into the fixing cavity. The convex strip 312 is provided to facilitate the assembly of the bearing 32, and also facilitates the removal, replacement and maintenance of the bearing 32; and the provision of the guide slope 313 can guide the outer ring of the bearing 32 to slide smoothly into the fixing cavity, thereby reducing the installation resistance and improving the assembly efficiency.

[0041] In some embodiments, Figure 8 , Figure 10 As shown, a guide groove 314 is provided on the outer peripheral wall of the central fixing sleeve 31 and passes through the radial sides of the central fixing sleeve 31, and the spring buckle 51 is slidably arranged in the guide groove 314. The guide groove 314 limits the sliding direction of the spring buckle 51, so that it can only move along the radial direction of the central fixing sleeve 31, thereby avoiding the spring buckle 51 from twisting or getting stuck during the unlocking / locking process, and ensuring the reliability and smoothness of the self-locking mechanism 50. In addition, when the compression spring 52 is accommodated in the central fixing sleeve 31, mounting holes are recessed on the inner side surfaces of the two spring buckles 51 facing each other, and the two ends of the compression spring 52 are embedded in the corresponding mounting holes to improve the stability of the compression spring 52 when it is compressed and restored.

[0042] In some embodiments, Figure 7 , Figure 8 , Figure 10As shown, one axial end of the central fixing sleeve 31 is provided with an end cover 33 to prevent the snap button 51 from disengaging from the central fixing sleeve 31. The end cover 33 is provided with a limiting groove 331 corresponding to the position of each snap button 51 and communicating with the guiding groove 314. The pressing portion 53 of the snap button 51 extends out from the corresponding limiting groove 331, and the limiting groove 331 is used to limit the moving range of the pressing portion 53. In this embodiment, the end cover 33 serves as a closed structure at the axial end of the central fixing sleeve 31 and can be specifically locked on the central fixing sleeve 31 by two screws. The main function of the end cover 33 is to physically block the axial movement of the snap button 51 along the central fixing sleeve 31 and prevent it from disengaging from the central fixing sleeve 31. At the same time, the limiting groove 331 on the end cover 33 is used to limit the sliding stroke of the pressing portion 53 on the snap button 51, which can prevent the user from pressing the pressing portion 53 excessively during operation and avoid blind force application, thereby preventing the compression spring 52 from being excessively compressed and causing damage or shortened lifespan.

[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 runner 20, and an elastic positioning structure 60 is arranged at the position corresponding to the positioning shaft 45 in the drawing port 11; when the runner module 100 is inserted into the drawing 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 piece or other components made of elastic materials with elastic deformation ability. When the runner module 100 slides and inserts along the drawing port 11, the positioning shaft 45 will gradually approach the elastic positioning structure 60 and will ultimately be firmly clamped or stuck by the elastic positioning structure 60, providing a stable rotation axis center for the subsequent smooth rotation of the runner 20 and reducing the performance degradation that may be caused by slight vibration or position deviation.

[0044] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 , Figure 6As shown, a sliding groove 12 is provided along the inner edge of the pulling port 11 in a direction parallel to the pulling direction of the rotating wheel module 100. The support arm 41 is slidably engaged with the sliding groove 12. The sliding groove 12 can provide precise guidance for the insertion and extraction of the rotating wheel module 100, ensuring the stability and smoothness of the rotating wheel module 100 during movement. At the same time, the elastic positioning structure 60 includes two elastic clamping arms 61 oppositely arranged at the bottom of the sliding groove 12, and 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 an elastic material and have a certain ability to open and close. When the positioning shaft 45 on the mounting frame 40 enters between the two elastic clamping arms 61 as the rotating wheel module 100 is inserted, the elastic clamping arms 61 will elastically open to both sides. After the positioning shaft 45 completely enters the predetermined position, the elastic clamping arms 61 will clamp the positioning shaft 45 by relying on their own elastic restoring force and provide sufficient clamping force to prevent the rotating wheel module 100 from accidentally loosening or slipping out during use, while also facilitating the user to apply an appropriate pulling force to take it out when needed.

[0045] In a specific example, such as Figure 2 、 Figure 5 As shown, both of the two elastic clamping arms 61 include a guiding section 611, an arc-shaped positioning section 612, and a straight section 613 arranged in sequence along the insertion direction of the rotating wheel module 100. The two guiding sections 611 form a guiding port with a gradually expanding opening relatively. Even if the user's insertion angle is slightly skewed, the positioning shaft 45 will be gradually guided to the correct path by the guiding 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, and the mounting frame 40 is relatively fixed to the frame 10 to prevent accidental slipping. The other ends of the two straight sections 613 are connected to the groove wall of the sliding groove 12 to provide support. In addition, a limiting protrusion 614 extending along the length direction parallel to the straight section 613 is provided between the two straight sections 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 and ensure accurate and reliable positioning.

[0046] In some embodiments, such as Figure 4 、 Figure 5 、 Figure 6As shown, the opposite groove walls of the sliding groove 12 are respectively provided with limiting blocks 13 to form a limiting groove 331 within the sliding groove 12. The two sides of the support arm 41 are respectively inserted into the limiting groove 331, and the limiting blocks 13 abut against one side of the support arm 41 facing the runner 20. With this structural design, when the runner module 100 slides to the end along the sliding groove 12, the two sides in the width direction of the support arm 41 are respectively inserted into the limiting groove 331, so as to form a position limit for the support arm 41, that is, the entire runner module 100 in the axial direction, and it is not easy to shake.

[0047] On the surface of the limiting block 13 relative to the insertion direction of the runner module 100, a guiding inclined surface 131 extending into the limiting groove 331 is provided, and a positioning wedge block 411 is provided at the position of the distal end of the support arm 41 corresponding to the guiding inclined surface 131. The guiding inclined surface 131 can guide the positioning wedge block 411 of the support arm 41 to smoothly enter the limiting groove 331, reduce the assembly resistance, and facilitate the user's operation.

[0048] In some embodiments, a handle is provided on the side of the mounting bracket 40 facing away from the support arm 41, which facilitates the user's operation; or, as Figure 1 、 Figure 4 、 Figure 7 shown, the mounting bracket 40 has a hollow structure, and a pulling position 47 suitable for being grasped by a human hand is formed on the side of the hollow structure facing away from the support arm 41. The hollow structure directly forms a natural handle, that is, the pulling position 47, which enables the user to directly grasp the pulling position 47 for pulling operation without additionally installing a handle or other auxiliary structures on the mounting bracket 40. At the same time, by using the hollow mounting bracket 40, the weight of itself can be effectively reduced on the premise of ensuring sufficient structural strength, and further the weight of the entire runner module 100 can be reduced.

[0049] In some embodiments, as Figure 3 、 Figure 4 、 Figure 7 shown, a circular frame 46 for accommodating the runner 20 is provided on the mounting bracket 40. The circular frame 46 surrounds the periphery of the runner 20, which can effectively prevent the runner module 100 from being accidentally impacted or squeezed during handling or use and causing damage. The distal end of the support arm 41 extends to the axis of the circular frame 46. Specifically, as Figure 7 shown, a plurality of reinforcing ribs 463 extending along the horizontal and / or vertical directions are provided on the circular frame 46, and at least part of the plurality of reinforcing ribs 463 is connected to the support arm 41. These reinforcing ribs 463 can effectively disperse various forces received by the circular frame 46 and improve its bending resistance and impact resistance. In a specific example, as Figure 7As shown, two horizontally extending reinforcing ribs and one vertically extending reinforcing rib are provided in the circular frame 46, and the vertically extending reinforcing rib 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 formed in an integral structure, for example, by one-step molding using an injection molding process, so that when a single support arm 41 is provided, the synergistic effect of the multiple reinforcing ribs 463 on the circular frame 46 and the support arm 41 can still ensure the stability of the runner 20 during operation.

[0050] At the same time, the dehumidifier also includes a driving assembly for driving the rotating wheel 20 to rotate. The driving assembly includes a driving motor fixed on the frame 10, a driving wheel 14 rotatably mounted on the frame 10, and a driven wheel 15 rotatably mounted on the mounting frame 40 or the frame 10. The output shaft of the driving motor is connected to the driving wheel 14. The outer periphery of the rotating wheel 20 is sleeved with a gear ring 21. The outer peripheral surface of the circular frame 46 is provided with a first notch 461 and a second notch 462. The driving wheel 14 extends into the first notch 461 and meshes with the gear ring 21. The driven wheel 15 extends into the second notch 462 and meshes with the gear ring 21 to achieve the driving of the rotating wheel 20. At the same time, the driving wheel 14 and the driven wheel 15 are extended into the notches on the outer peripheral surface of the circular frame 46. This can reduce the volume of the entire driving assembly, make the structure more compact, and save space. In addition, the first notch 461 and the second notch 462 are located at two radially opposite ends of the circular frame 46. In specific implementation, as Figure 3 As shown, the driven wheel 15 is arranged below the rotating wheel 20 to the left, so that the line connecting the centers of the rotating shafts of the driven wheel 15 and the driving wheel 14 does not pass through the center of the circle of the rotating wheel 20. This is equivalent to providing an additional support point for the rotating wheel 20 to reduce the load of the driving wheel 14, thereby reducing the risk of the rotating wheel 20 getting stuck. The additional support formed by the driven wheel 15 can also effectively prevent the rotating wheel 20 from being deformed or tilted, thereby ensuring the normal operation of the driving mechanism.

[0051] like Figure 8 As shown, the wheel module 100 further includes an outer frame 70, which is made of stainless steel, such as 304 stainless steel, and is not easy to rust or corrode. The outer frame 70 includes a concentrically arranged center seat 71 and a circular sleeve frame 72, and a plurality of spokes 73 connected between the center seat 71 and the sleeve frame 72. One end of the wheel 20 is accommodated in the sleeve frame 72 to protect the wheel 20. Specifically, the sleeve frame 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 convenient for disassembly for maintenance or replacement when necessary.

[0052] The dehumidifier with a replaceable runner provided in this embodiment integrates the runner, the rotating shaft assembly and the mounting frame into a runner module that can be pulled out and inserted along the machine frame. Different from the design with a fixed runner, it realizes the convenient removal and installation of the runner. When necessary maintenance and inspection are required, there is no need to disassemble the dehumidifier frame and other internal components tediously, which greatly simplifies the replacement and maintenance operations of the runner. Even ordinary users without professional tools and skills can easily complete it. At the same time, the convenient maintainability also indirectly extends the service life of the dehumidifier and reduces the scrapping of the whole machine due to minor faults. Therefore, the design of this application not only improves the maintenance efficiency of the dehumidifier, but also reduces the maintenance threshold, and ultimately brings a more economical, convenient and sustainable dehumidification experience to users.
