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 casing, an air duct inside the casing, a rotor inside 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 impeller becomes clogged or deformed, the entire unit is scrapped. Replacing the impeller is extremely complicated. In existing dehumidifier structures, the impeller is usually fixed inside the casing, 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 impeller is located. Furthermore, because the impeller 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 impeller 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 impeller 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

[0012] Secondly, embodiments of this application provide a dehumidifier, including a rotary module as described in any embodiment of the first aspect, and a main support frame. The main support frame is provided with an air duct and a pull-out port suitable for inserting and removing the rotary module. The rotary module is used to dehumidify the air flowing through the air duct and is configured to be removably inserted into and removed from the dehumidifier through the pull-out port.

Detailed Implementation

[0024] 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.

[0025] In the first aspect, this application provides a rotary module 100, mainly used in the dehumidification process of a rotary dehumidifier, and can be used in conjunction with the regeneration fan and heater of the rotary dehumidifier for cyclic regeneration. For detailed working process, please refer to the rotary dehumidifier provided in the second aspect of the following description. Figures 1 to 3 As shown, the dehumidifier module 100 mainly includes a dehumidifier wheel 10, a mounting bracket 20, and a rotating shaft assembly 30 located at the rotation axis of the dehumidifier wheel 10. It aims to enable convenient replacement of the dehumidifier wheel 10 without disassembling the main structure of the dehumidifier, thereby improving the maintainability of the dehumidifier.

[0026] Specifically, the mounting bracket 20 has a support arm 21 extending toward the rotation axis of the dehumidifying wheel 10; the dehumidifying wheel 10 is rotatably mounted on the support arm 21 via a rotating shaft assembly 30; the rotating shaft assembly 30 is detachably connected to the support arm 21, and the rotating shaft assembly 30 detachably fixes the dehumidifying wheel 10. In this way, the dehumidifying wheel 10, together with the mounting bracket 20 and the support arm 21, forms an independent rotating wheel module 100. This integrated, detachable rotating wheel module 100 allows for maintenance operations such as cleaning and replacing the dehumidifying wheel 10 without disassembling the main structure of the dehumidifier. The entire rotating wheel module 100 can be directly removed from the dehumidifier for maintenance operations outside the dehumidifier, providing more operating space, requiring less professional knowledge and operating skills, and reducing maintenance difficulty.

[0027] In this embodiment, as Figure 3 As shown, there are two support arms 21 arranged opposite each other, located on opposite sides of the dehumidification wheel 10. This achieves symmetrical support for both sides of the dehumidification wheel 10, reduces the force on a single support arm 21, and makes the dehumidification wheel 10 more evenly stressed and more stable during operation.

[0028] In one specific embodiment, such as Figure 2 , Figure 3As shown, the rotating shaft assembly 30 includes a bushing 31, a threaded fastener 32, and a fixing sleeve 33. The bushing 31 is located at the rotation axis of the dehumidifying wheel 10, serving as a rotational support and reducing friction during rotation. One support arm 21 passes through the bushing 31 via the threaded fastener 32 and is threadedly engaged with the fixing sleeve 33 on the other support arm 21, thereby rotatably fixing the dehumidifying wheel 10 between the two support arms 21. When the dehumidifying wheel 10 needs to be replaced, the rotating shaft assembly 30 can be detachably connected to the support arm 21 by loosening the threaded fastener 32, such as a hand-tightening bolt, and the dehumidifying wheel 10 can be further removed from the mounting bracket 20 for replacement. The process is simple and quick, requiring no complicated tools or operations.

[0029] In some embodiments, a handle (not shown) is provided on the side of the mounting bracket 20 away from the center of the dehumidifying wheel 10 to facilitate the removal of the entire rotating wheel module 100; or, as... Figure 2 , Figure 3 As shown, the mounting bracket 20 has a hollow structure, with a pull-out position 22 for hand gripping formed on the side of the hollow structure away from the center of the dehumidifying wheel 10. The hollow structure effectively reduces the weight of the mounting bracket 20 while ensuring its structural strength, and directly forms a natural handle, i.e., the pull-out position 22. This allows users to directly grasp the pull-out position 22 for pulling operations, eliminating the need for additional handles or other auxiliary structures on the mounting bracket 20, and also reducing the weight of the entire rotating wheel module 100. In a specific example, such as... Figure 3 As shown, the mounting bracket 20 has an extension section 24 near the pull-out position 22. The extension section 24 extends toward the axis of the dehumidifying wheel 10, which makes the pull-out position 22 more spacious for a person to reach in, and also enhances the structural strength of the mounting bracket 20 with its hollow structure.

[0030] In some embodiments, such as Figure 1 , Figure 3 As shown, the support arm 21 has a hollow structure. The hollow structure effectively reduces the amount of material used while ensuring that the support arm 21 has sufficient strength and rigidity, thereby reducing the overall weight of the wheel module 100 and reducing wind resistance.

[0031] In some embodiments, such as Figure 1 , Figure 3 As shown, the cross-sectional area of ​​the support arm 21 gradually decreases from one end to the end closer to the rotating shaft assembly 30. The design of the gradually decreasing cross-sectional area of ​​the support arm 21 can effectively reduce the obstruction of the airflow through the dehumidifying wheel 10 by the support arm 21, reduce wind resistance, and also facilitate the guidance of the support arm 21 when it is inserted.

[0032] Secondly, such as Figures 2 to 4As shown, this application provides a dehumidifier, including a rotary wheel module 100 according to any embodiment of the first aspect, and a main support 40. The main support 40 is provided with an air duct and a pull-out port 50 suitable for inserting and removing the rotary wheel module 100. The rotary wheel module 100 is used to dehumidify the air flowing through the air duct and is configured to be removably inserted and removed through the pull-out port 50. In specific implementation, a heat exchanger 41, a fan 42, and a heater 43 are also provided in the air duct. When the dehumidifier is working, the fan 42 drives the air to flow along the duct: after passing through the heat exchanger 41, the air enters the dehumidification wheel 10 of the rotary wheel module 100. When the humid air passes through the dehumidification wheel 10, the moisture-absorbing material of the dehumidification wheel 10 absorbs the moisture in the air, thereby achieving dehumidification. In order to maintain the continuous moisture absorption capacity of the dehumidification wheel 10, the heater 43 heats the regeneration area of ​​the dehumidification wheel 10, so that the absorbed moisture evaporates and is carried away by the regeneration airflow, completing the dehumidification cycle.

[0033] Specifically, the dehumidifier wheel module 100 is designed as a separate component that can be removed from the main support frame 40 of the dehumidifier. The dehumidifier wheel module 100 does not connect to the heat exchanger 41, fan 42, heater 43, or any other additional functional components. The position, shape, and size of the pull-out port 50 are adapted to the dehumidifier wheel module 100, making the maintenance and replacement of the dehumidifier wheel 10 extremely convenient. When the dehumidifier wheel 10 needs maintenance or replacement due to prolonged use, decreased moisture absorption performance, or other reasons, the user does not need to disassemble the dehumidifier casing or other components on the main support frame 40 as with traditional dehumidifiers. The entire dehumidifier wheel module 100 can be directly pulled out of the main support frame 40 through the pull-out port 50. After maintenance or replacement, the user can then push the dehumidifier wheel module 100 (new or maintained) back into the main support frame 40 along the pull-out port 50. The entire process requires no professional tools or skills and can be completed by ordinary users themselves, greatly reducing maintenance costs and time investment. In this embodiment, the dehumidifying wheel 10 is arranged vertically, and the pull-out port 50 is located on the side or top of the main support 40 for convenient operation. Furthermore, to improve sealing and aesthetics, an openable and closable sealing cover (not shown) can be provided at the pull-out port 50. The sealing cover can adopt various opening and closing methods, such as flip-top, push-pull, or rotating types. When the wheel module 100 is inserted into place, the sealing cover closes the pull-out port 50 to prevent dust, foreign objects, etc., from entering the dehumidifier and to maintain the cleanliness of the dehumidifier's appearance.

[0034] In some embodiments, such as Figure 2 , Figure 3As shown, elastic buckles 23 are respectively provided on both sides of the mounting bracket 20 along its length, and locking holes 51 that cooperate with the elastic buckles 23 are provided in the pull-out opening 50. When the rotary wheel module 100 is inserted into the pull-out opening 50, the elastic buckles 23 engage with the locking holes 51 to fix the rotary wheel module 100 on the main support 40, preventing it from accidentally sliding out of the pull-out opening 50 due to vibration, tilting, or other reasons during use. During assembly, simply push the rotary wheel module 100 into the pull-out opening 50, and the elastic buckles 23 will automatically slide in and engage with the locking holes 51, completing the fixation without any tools. During disassembly, usually only a slight force is needed to pull the rotary wheel module 100 outward, and the elastic buckles 23 will automatically disengage from the locking holes 51, again achieving quick disassembly without tools, greatly facilitating user maintenance and replacement operations.

[0035] In some embodiments, such as Figures 1 to 3 As shown, it also includes a drive assembly for driving the dehumidifying wheel 10 to rotate. The drive assembly includes a drive motor fixed on the main body bracket 40 and a drive wheel rotatably mounted on the main body bracket 40. The output shaft of the drive motor is connected to the drive wheel. A gear ring 11 is sleeved on the outer circumference of the dehumidifying wheel 10. The drive wheel extends into the pull-out port 50 and meshes with the gear ring 11 to realize the rotation drive of the dehumidifying wheel 10.

[0036] In some embodiments, such as Figure 1 , Figure 3 , Figure 5 (As shown in the figure, the dehumidifying wheel 10 has been removed) A groove 52 is provided inside the pull-out opening 50 along the pull-out direction parallel to the rotating wheel module 100. The support arm 21 slides in conjunction with the groove 52 to guide the entire rotating wheel module 100 when it is pulled out. Limiting blocks 53 are protruding from the opposite walls of the groove 52 to form limiting grooves in the groove 52. Parts of the support arm 21 on both sides are inserted into the limiting grooves, and the limiting blocks 53 abut against the side of the support arm 21 facing the dehumidifying wheel 10. In this way, the limiting blocks 53 restrict the axial movement of the support arm 21 along the dehumidifying wheel 10, thereby restricting the axial shaking of the rotating wheel module 100. With the setting of the elastic buckle 23 and the locking hole 51, the dehumidifying wheel 10 of the rotating wheel module 100 can maintain a stable state after it is assembled with the main support 40, and is not easy to shake and cause the teeth to jam.

[0037] In some embodiments, such as Figures 1 to 3 As shown, the length of the mounting bracket 20 is adapted to the width of the pull-out opening 50. The side of the mounting bracket 20 closest to the dehumidifying wheel 10 is arc-shaped, and the length of the mounting bracket 20 is greater than the diameter of the dehumidifying wheel 10. This provides a stable support base without affecting the operation of the dehumidifying wheel 10.

[0038] In some embodiments, such as Figure 1 , Figure 3 , Figure 4As shown, the support arm 21 has a proximal end and a distal end. The proximal end is connected to the mounting bracket 20, and the distal end is away from the mounting bracket 20. A positioning notch 211 is provided at the end of the support arm 21 away from the mounting bracket 20, and a positioning protrusion 521 corresponding to the position of the positioning notch 211 is provided in the slide groove 52. When the rotary wheel module 100 is fully inserted into place along the slide groove 52, the positioning notch 211 at the distal end of the support arm 21 away from the mounting bracket 20 will insert into the positioning protrusion 521, clearly defining the insertion limit position of the rotary wheel module 100. At this time, the user will clearly feel an increase in resistance during the process of pushing the rotary wheel module 100 in. This tactile feedback clearly informs the user that the rotary wheel module 100 has been installed in place, effectively avoiding the risk of incomplete or incorrect installation.

[0039] The rotary dehumidifier and dehumidifier provided in this embodiment integrate the dehumidifying wheel, shaft assembly, and mounting bracket into a single, pull-out module. This allows for convenient removal and installation of the dehumidifying wheel, eliminating the need to disassemble the dehumidifier casing and other internal components during necessary maintenance. This greatly simplifies the replacement and maintenance of the dehumidifying wheel, allowing ordinary users to complete the process without specialized tools or skills. This effectively reduces long-term operating costs and extends the lifespan of the dehumidifier, ultimately providing users with a more economical, convenient, and sustainable dehumidification experience.
