Description

Technical Field

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

[0002] A rotary dehumidifier is a commonly used air humidity control device, widely used 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 processing (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 tools like screwdrivers 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 and a dehumidifier with a resonator that allows for easy maintenance and replacement of the resonator.

[0007] To achieve the above objectives, in a first aspect, embodiments of this application provide a rotary wheel module, including a main frame, a rotary wheel, and a rotating shaft assembly. One side of the main frame is provided with a circular frame for accommodating the rotary wheel, and a support arm is provided inside the circular frame. The distal end of the support arm extends to the axis of the circular frame. The rotary wheel is rotatably and detachably mounted to the distal end of the support arm via the rotating shaft assembly.

[0008] A further embodiment is that elastic buckles are provided on opposite sides of the main frame along its length. When the rotary module is inserted into the pull-out opening of the dehumidifier's frame, the elastic buckles can engage with the locking holes of the frame to fix the position of the rotary module.

[0009] A further option is to provide a handle on the side of the main frame away from the support arm; or, the main frame 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.

[0010] A further option is that the support arm has a hollow structure.

[0011] A further embodiment is that the circular frame is provided with multiple reinforcing ribs extending horizontally and / or vertically, and at least a portion of the multiple reinforcing ribs are connected to the support arm.

[0012] A further embodiment is that the rotating shaft assembly is provided with a self-locking mechanism, which has a locked state and an unlocked state. When the self-locking mechanism is in the locked state, it locks the rotating wheel onto the rotating shaft assembly. When the self-locking mechanism is in the unlocked state, the rotating wheel can be removed from the rotating shaft assembly.

[0013] Secondly, embodiments of this application provide a dehumidifier, including a rotary module as described in any embodiment of the first aspect, and a frame. The frame is provided with an air duct and a pull-out port suitable for inserting and removing the rotary module. The rotary wheel in the rotary module is used to dehumidify the air flowing through the air duct. The rotary module is removably inserted into and removed from the frame through the pull-out port.

[0014] A further embodiment 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 frame or main body 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 is provided on the outer circumferential surface of the circular frame. The drive wheel extends into the first notch and meshes with the gear ring. A second notch is provided on the outer circumferential surface of the circular frame. The driven wheel extends into the second notch and meshes with the gear ring. The first notch and the second notch are located at two radially opposite ends of the circular frame.

[0015] A further embodiment includes an outer frame made of stainless steel. The outer frame includes a concentrically arranged central seat and a circular sleeve, as well as multiple spokes connecting the central seat and the sleeve. One end of the wheel is housed in the sleeve, which is connected to the gear ring by a first screw. The central seat is connected to the shaft assembly by a second screw.

[0016] A further embodiment is that the far end of the support arm is provided with a positioning shaft located at the rotation axis of the rotating wheel; two elastic clamping arms are provided in the pull-out opening of the frame, and their positions match the positioning shaft; when the rotating wheel module is inserted into the pull-out opening, the two elastic clamping arms clamp and position the positioning shaft.

[0017] The rotary module and dehumidifier designed in this application integrate the rotary wheel and shaft assembly into the main frame to form an independent, pull-out rotary module. This not only enables convenient removal and installation of the rotary wheel, eliminating the tedious steps of disassembling the dehumidifier casing and other internal components during necessary maintenance, but also lowers the technical threshold for maintenance. This allows ordinary users to easily complete maintenance without professional tools and skills, thereby effectively reducing the long-term operating costs for users, significantly extending the service life of the dehumidifier, and ultimately bringing users a more economical, convenient, and sustainable dehumidification experience.

Detailed Implementation

[0028] 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.

[0029] Firstly, such as Figure 1 , Figure 2 As shown, this application embodiment provides a rotary wheel module 100, including a main frame 10, a rotary wheel 20, and a rotating shaft assembly 30. A circular frame 40 for accommodating the rotary wheel 20 is provided on one side of the main frame 10. Specifically, the circular frame 40 is a circular structure integrally formed with the main frame 10, used to fix and protect the rotary wheel 20. A support arm 50 is provided inside the circular frame 40. The support arm 50 has a proximal end close to the main frame 10 and a distal end away from the main frame 10, and the distal end of the support arm 50 extends to the axis of the circular frame 40. The rotary wheel 20 is rotatably and detachably mounted on the distal end of the support arm 50 through the rotating shaft assembly 30, and works together with the support arm 50 to provide reliable rotational support for the rotary wheel 20.

[0030] When maintenance or replacement of the roller 20 is required, the roller 20 can be easily removed from the support arm 50 by simply operating the shaft assembly 30. This allows for convenient individual cleaning, inspection, or replacement of the roller 20. The entire process is simple and quick, requiring no complicated tools or professional skills. The detailed structure and operation of the shaft assembly 30 will be explained in detail later.

[0031] In practical implementation, to facilitate the installation and fixation of the rotary module 100 in the dehumidifier, such as Figure 1 As shown, elastic buckles 11 are respectively provided on both sides of the main frame 10 along its length. When the rotary module 100 is inserted into the pull-out opening of the dehumidifier's frame, the elastic buckles 11 can engage with the locking holes of the frame to fix the position of the rotary module 100. With this structural design, the rotary module 100 is configured to be installed in the pull-out opening of the dehumidifier's frame in a pull-out manner. The user only needs to push gently to install the rotary module 100 into place. At the same time, the engaging action of the elastic buckles can effectively prevent the rotary module 100 from accidentally sliding out of the pull-out opening due to vibration or tilting during use, thus ensuring good stability.

[0032] In some embodiments, a handle is provided on the side of the main frame 10 opposite to the support arm 50 to facilitate the pull-out operation of the rotary module 100. In another specific example, such as Figure 1 As shown, the main frame 10 has a hollow structure, and a pull-out position 12 suitable for hand gripping is formed on the side of the hollow structure opposite to the support arm 50. In this way, the hollow structure directly forms a natural handle, namely the pull-out position 12, which allows users to directly grasp the pull-out position 12 for pull-out operation without the need to install additional handles or other auxiliary structures on the main frame 10. At the same time, the use of a hollow main frame 10 can effectively reduce its own weight while ensuring sufficient structural strength, thereby reducing the weight of the entire rotary module 100.

[0033] In some embodiments, such as Figure 2 As shown, the support arm 50 has a hollow structure. This hollow structure effectively reduces material usage while ensuring sufficient strength and rigidity of the support arm 50, thereby reducing the overall weight. In this embodiment, as... Figure 2 As shown, the cross-sectional area of ​​the support arm 50 gradually decreases towards the far end, which can effectively reduce the obstruction of the airflow through the impeller 20 by the support arm 50 and reduce wind resistance.

[0034] In some embodiments, the circular frame 40 is provided with a plurality of reinforcing ribs 41 extending horizontally and / or vertically, at least a portion of which are connected to the support arm 50. These reinforcing ribs 41 can effectively distribute various forces acting on the circular frame 40, improving its bending and impact resistance. In a specific example, such as... Figure 2 , Figure 3 As shown, the circular frame 40 is provided with two horizontally extending reinforcing ribs and one vertically extending reinforcing rib, which is connected to the support arm 50. In this embodiment, the main frame 10, the circular frame 40, the support arm 50, and the reinforcing rib 41 can be integrally molded, for example, by injection molding. This ensures that even with a single support arm 50, the smooth operation of the wheel 20 during operation can still be guaranteed by the synergistic effect of the multiple reinforcing ribs 41 on the circular frame 40 and the support arm 50.

[0035] In some embodiments, such as Figures 2 to 6 As shown, the rotating shaft assembly 30 is provided with a self-locking mechanism 31. The self-locking mechanism 31 has a locked state and an unlocked state. When the self-locking mechanism 31 is in the locked state, it locks the rotating wheel 20 onto the rotating shaft assembly 30. When the self-locking mechanism 31 is in the unlocked state, the rotating wheel 20 can be removed from the rotating shaft assembly 30.

[0036] Specifically, such as Figure 4 , Figure 5 , Figure 6 As shown, the rotating shaft assembly 30 includes a hollow cylindrical central sleeve disposed at the rotation axis of the rotating wheel 20. The self-locking mechanism 31 includes two opposing spring clips 32 and an elastic element 33 disposed between the two spring clips 32. It is used to provide the two spring clips 32 with a driving force to lock the rotating wheel 20 to the central sleeve, and to drive the spring clips 32 to reset to the locked position after the external force is released.

[0037] Two spring clips 32 are slidably connected to the central sleeve along the radial direction of the rotating wheel 20 and can move between a locked position and an unlocked position. When no external force is applied, the two spring clips 32 are in the locked position and lock the rotating wheel 20 to the central sleeve by the elastic force of the elastic element 33. When the two spring clips 32 are pressed by an external force, they move from the locked position to the unlocked position so that the rotating wheel 20 can be removed from the central sleeve. When it is necessary to disassemble the rotating wheel 20, the operator only needs to apply external force to press the two spring clips 32 until the elastic force of the elastic element 33 is overcome, so that the two spring clips 32 move from the locked position to the unlocked position. That is, in the unlocked position, the locking structure of the spring clips 32 will completely retract into the center sleeve, or at least no longer obstruct or restrict the position of the rotating wheel 20 in the axial direction of the center sleeve. At this time, the locking state between the rotating wheel 20 and the rotating shaft assembly 30 is released, and the user can easily and quickly remove the rotating wheel 20 from the center sleeve for subsequent cleaning, inspection or replacement operations without the need for additional tools or professional skills.

[0038] Furthermore, such as Figure 5 , Figure 6As shown, each of the two snap-fit ​​buttons 32 has a locking part 321 on one side facing away from each other. In the locked position, the locking part 321 protrudes from the outer peripheral surface of the central sleeve and abuts against the inner peripheral wall of the rotating wheel 20. This direct physical contact and abutment can provide an effective radial locking force to prevent the rotating wheel 20 from shaking or radially displacing relative to the central sleeve during normal operation. In the unlocked position, the locking part 321 is housed in the central sleeve and no longer contacts or applies locking force to the inner peripheral wall of the rotating wheel 20, making it easy to unlock.

[0039] Furthermore, such as Figure 6 As shown, the surface of the clamping part 321 that abuts against the rotating wheel 20 is an arc surface that matches the inner peripheral wall of the rotating wheel 20. The arc surface and the inner peripheral wall of the rotating wheel 20 can provide a larger actual contact area, and an anti-slip structure is provided on the arc surface to increase the friction between the arc surface and the inner peripheral wall of the rotating wheel 20. 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.

[0040] Furthermore, such as Figure 5 As shown, a guide groove 34 is formed on the outer peripheral wall of the central sleeve, penetrating both radial sides of the central sleeve. The spring clip 32 is slidably disposed in the guide groove 34, allowing the spring clip 32 to slide freely only in the radial direction of the central sleeve, ensuring stable operation. The elastic element 33 is a spring disposed within the guide groove 34 and abutting against the two spring clips 32. When the spring clip 32 is in the locked and unlocked positions, the spring is in a compressed state. In specific implementation, as follows... Figure 3 As shown, mounting holes are recessed on the inner surfaces of the two spring clips 32 facing each other, and the two ends of the elastic element 33 are fitted into the corresponding mounting holes to improve the stability of the elastic element 33 when it is compressed and restored.

[0041] Furthermore, such as Figure 2 , Figure 5 As shown, the two spring clips 32 are provided with pressing parts 35 that are suitable for human hand operation. The protruding pressing parts 35 are directly exposed to the outside of the central sleeve, providing the user 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 the user to apply pressing force to unlock.

[0042] Furthermore, such as Figure 3 , Figure 5As shown, one end cap of the central sleeve is provided with an end cap 36 to prevent the spring clip 32 from dislodging from the central sleeve. The end cap 36 has a limiting groove 37 corresponding to the position of each spring clip 32, which communicates with the guide groove 34. The pressing part 35 of the spring clip 32 extends out from the corresponding limiting groove 37. The limiting groove 37 is used to limit the movement range of the pressing part 35. In this embodiment, the end cap 36 serves as a closed structure at the axial end of the central sleeve. Specifically, it can be locked onto the central sleeve by two screws. The main function of the end cap 36 is to physically prevent the spring clip 32 from moving along the axial direction of the central sleeve and dislodging from the central sleeve. At the same time, the limiting groove 37 on the end cap 36 limits the sliding stroke of the pressing part 35 on the spring clip 32, which can prevent the user from excessively pressing the pressing part 35 during operation, avoid blindly applying force, and thus prevent the spring 30 from being over-compressed, resulting in damage or shortened life.

[0043] Secondly, such as Figure 7 , Figure 9 As shown, this application provides a dehumidifier, including a rotary module 100 according to any embodiment of the first aspect, and a frame 60. The frame 60 has an air duct and a pull-out port 61 suitable for inserting and removing the rotary module 100. The rotary wheel 20 in the rotary module 100 is used to dehumidify the air flowing through the air duct. The rotary module 100 can be removably inserted into and removed from the frame 60 through the pull-out port 61. Therefore, the rotary module 100 can be conveniently and removably inserted into and removed from the frame 60 through the pull-out port 61, enabling quick replacement and maintenance.

[0044] With the above structure, the independent rotor module 100 does not need to be directly connected to other functional components commonly found in dehumidifiers, such as dehumidification, heat exchange, airflow drive, or heating. This means that when maintenance or replacement of the rotor 20 is required, users do not need to perform cumbersome disassembly operations, such as removing components like the fan or heater. They can easily remove the entire rotor module 100 from the dehumidifier simply by using the pull-out port 61 on the frame 60. In other words, cleaning, inspection, or replacement of the rotor 20 can all be performed after the module is removed, providing more space and making the process more convenient and faster. For example, users can simply press the spring clip 32 on the rotor assembly to remove the rotor 20 from the circular frame 40, making the replacement process very simple and intuitive.

[0045] To ensure the stability and smoothness of the rotary module 100 during insertion and withdrawal, in a specific example, such as Figure 9 As shown, a slide groove 611 adapted to the support arm 50 on the frame 60 can also be provided on the inner wall of the pull-out port 61. The slide groove 611 can provide precise guidance for the insertion and extraction of the rotary module 100, ensuring the stability and smoothness of the rotary module 100 during movement.

[0046] In some embodiments, such as Figure 8, Figure 9 As shown, it also includes a drive assembly for driving the rotating wheel 20 to rotate. The drive assembly includes a drive motor fixed to the frame 60, a drive wheel 62 rotatably mounted on the frame 60, and a driven wheel 63 rotatably mounted on the frame 60 or the main frame 10. The output shaft of the drive motor is connected to the drive wheel 62. A gear ring 21 is fitted around the outer circumference of the rotating wheel 20. A first notch 42 is provided on the outer circumferential surface of the circular frame 40. The drive wheel 62 extends into the first notch 42 and meshes with the gear ring 21. A second notch 43 is provided on the outer circumferential surface of the circular frame 40. The driven wheel 63 extends into the second notch 43 and meshes with the gear ring 21 to drive the rotating wheel 20. Simultaneously, extending the drive wheel 62 and the driven wheel 63 into the notches on the outer circumferential surface of the circular frame 40 can reduce the volume of the entire drive assembly, making the structure more compact and saving space. Furthermore, the first notch 42 and the second notch 43 are located at the radially opposite ends of the circular frame 40. In specific implementations, as shown... Figure 8 As shown, the driven wheel 63 is positioned below the rotating wheel 20 on the left, so that the line connecting the centers of the shafts of the driven wheel 63 and the driving wheel 62 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, thereby reducing the load on the driving wheel 62 and reducing the risk of the rotating wheel 20 jamming.

[0047] In some embodiments, such as Figure 3 As shown, the wheel module 100 also includes an outer frame 70, which is made of stainless steel, such as 304 stainless steel. This stainless steel has good high-temperature resistance, corrosion resistance, and a long service life, ensuring stable operation of the outer frame 70. Specifically, 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, which is connected to the gear ring 21 by a first screw 74. The center seat 71 is connected to the shaft assembly 30 by a second screw 75.

[0048] During specific assembly, the central sleeve is equipped with an annular baffle 38, a central screw 53, and a bearing 80, while the far end of the support arm 50 is equipped with a support shaft 52. The outer ring of the bearing 80 is interference-fitted with the inner circumferential wall of the central sleeve, and one end of the bearing 80 abuts against the side of the annular baffle 38 facing the support arm 50. The support arm 50 is equipped with an annular protrusion surrounding the outer circumference of the support shaft 52. One end of the annular protrusion extends into the central sleeve and abuts against the other end of the bearing 80, forming a bidirectional axial constraint on the bearing 80. One end of the support shaft 52 is connected to the central screw 53. The nut of the central screw 53 is pressed against the side of the annular baffle 38 away from the bearing 80. By tightening the central screw 53, the annular baffle 38 can be pressed to further enhance the axial fixing force and effectively prevent the bearing 80 from axially moving or loosening within the central sleeve, thus providing a simple and easy-to-assemble rotational support for the outer frame 70 to connect to the rotating wheel 20.

[0049] In addition, such as Figure 6 As shown, the inner circumferential wall of the central sleeve is provided with multiple convex ribs 81 at intervals. The multiple convex ribs 81 form a fixed cavity for receiving the bearing 80. The outer ring of the bearing 80 abuts against each convex rib 81. The end of the convex rib 81 is provided with a guide slope to facilitate the insertion of the bearing 80 into the assembly fixed cavity. The convex ribs 81 facilitate the assembly of the bearing 80 and also facilitate the removal, replacement and maintenance of the bearing 80; while the presence of the guide slope can guide the outer ring of the bearing 80 to slide smoothly into place, reducing installation resistance and improving assembly efficiency.

[0050] In some embodiments, such as Figure 5 , Figure 9 As shown, the distal end of the support arm 50 is provided with a positioning shaft 51 located at the rotation axis of the rotating wheel 20; two elastic clamping arms 64 are provided in the pull-out port 61 of the frame 60, whose positions match the positioning shaft 51; when the rotating wheel module 100 is inserted into the pull-out port 61, the two elastic clamping arms 64 clamp the positioning shaft 51. Specifically, the opening direction formed by the two elastic clamping arms 64 is consistent with the opening direction of the pull-out port 61. When the user pushes the rotating wheel module 100 to slide along the pull-out port 61 and assemble it into place, the positioning shaft 51 will naturally enter between the two elastic clamping arms 64. During this process, the elastic clamping arms 64 will first slightly open to allow the positioning shaft 51 to pass smoothly, and then quickly retract to tightly clamp the positioning shaft 51 to ensure the precise positioning of the rotating wheel module 100 in the frame 60, and provide a stable rotation axis center for the subsequent rotation of the rotating wheel 20, reducing performance degradation caused by vibration or offset.

[0051] The rotary wheel module and dehumidifier provided in this embodiment integrate the rotary wheel and shaft assembly into the main frame to form an independent, pull-out rotary wheel module. This not only enables convenient removal and installation of the rotary wheel, eliminating the tedious steps of disassembling the dehumidifier casing and other internal components during necessary maintenance, but also lowers the technical threshold for maintenance. This allows ordinary users to easily complete maintenance without professional tools and skills, thereby effectively reducing the long-term operating costs for users, significantly extending the service life of the dehumidifier, and ultimately bringing users a more economical, convenient, and sustainable dehumidification experience.
