Description

Technical Field

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

[0002] A rotary dehumidifier is a common air humidity control device used in homes, industries, and businesses. It typically consists of a frame, an air duct within the frame, a rotor within the duct, a drive mechanism to rotate the rotor, and other air conditioning components (such as a fan, heater, and heat exchanger). The fan drives air through the rotor, where the hygroscopic material on the rotor absorbs moisture from the air, thereby dehumidifying it.

[0003] However, during long-term use, the rotor of the existing rotary dehumidifier is prone to the following problems: First, since the rotary dehumidifier usually operates in an air environment, the air inevitably contains particles such as dust and impurities. These particles will enter the dehumidifier with the air and gradually deposit in the honeycomb pores of the rotor, causing pore blockage. The pore blockage will reduce the moisture absorption efficiency of the rotor, directly leading to a decrease in dehumidification performance; secondly, 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 temperature control is not accurate, can easily cause deformation of the rotor material, such as deformation of the honeycomb pores, smaller openings, etc., that is, wheel deformation will also reduce air circulation efficiency and moisture absorption area, further affecting the dehumidification effect.

[0004] Once the wheel has problems such as blockage or deformation, the traditional practice is to scrap the entire machine. If the wheel needs to be replaced, the operation is very cumbersome. In the existing rotary dehumidifier structure, the wheel is usually fixedly installed inside the frame, and its replacement operation is extremely inconvenient. When replacing, the user needs to use tools such as screwdrivers to dismantle the outer shell of the dehumidifier in order to access the internal space where the wheel is located. Moreover, since the wheel is usually tightly connected to other functional modules of the dehumidifier (for example, fans, heaters, air ducts, etc.), before removing the wheel, it is often necessary to remove these related components first to make room for the removal of the wheel. For example, it may be necessary to remove the treated air generation module and the regenerated air generation module connected to the wheel module.

[0005] Because disassembly is complex, involves multiple parts, and requires specialized knowledge and skills, replacing the rotor usually requires professional maintenance personnel. It is difficult for ordinary users to complete it themselves, resulting in high maintenance costs and a long time consumption. Summary of the Invention

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0025] The dehumidifier with replaceable rotor described in this embodiment is as follows: Figures 1 to 4 As shown. The dehumidifier frame 100 is provided with an air duct, and the rotor 10 is used to dehumidify the air flowing through the duct. Figure 1 As shown, a heat exchanger 40, a fan 50 and a heater 60 are also provided in the air duct. When the dehumidifier is working, the fan 50 drives the air to flow along the air duct. The air first passes through the heat exchanger 40 and then enters the rotor 10. When the humid air passes through the rotor 10, the hygroscopic material inside the rotor 10 absorbs the moisture in the air, thereby achieving dehumidification of the air. At the same time, in order to maintain the moisture absorption capacity of the rotor 10, the heater 60 will heat and regenerate the regeneration area of the rotor 10 to release the moisture adsorbed by the rotor and complete the dehumidification cycle.

[0026] like Figures 1 to 4 As shown, the dehumidifier further includes a shaft assembly 20 and a connecting frame 30. The rotor 10 is rotatably mounted on the connecting frame 30 via the shaft assembly 20 to form a rotor module 200. The frame 100 is provided with a pull-out opening 101 suitable for inserting and withdrawing the rotor module 200. The position and size of the pull-out opening 101 are adapted to the rotor module 200. The rotor module 200 is configured to be removably inserted into and withdrawn from the dehumidifier. In this way, the rotor 10 is assembled into an independent rotor module 200 via the shaft assembly 20 and the connecting frame 30. That is, the rotor module 200 of this embodiment is designed to be an independent component that can be removed from the dehumidifier. The rotor module 200 is not connected to other additional functional components such as the heat exchanger 40, the fan 50, and the heater 60. This provides the dehumidifier with the possibility of maintenance and reduces the production and use costs.

[0027] This modular design makes the maintenance and replacement of the wheel 10 extremely simple: when the wheel 10 needs to be maintained or replaced, for example, when the wheel has been used for too long, its moisture absorption performance has decreased, or when it needs to be cleaned, the user does not need to tediously disassemble the dehumidifier frame 100 and the internal heat exchanger 40, fan 50, heater 60 and other components as in a traditional dehumidifier. Instead, the user can directly pull the entire wheel module 200 out of the frame 100 through the pull-out opening 101 on the frame 100. Since the wheel module 200 is an independent component, subsequent maintenance operations such as cleaning and replacement of the wheel can be performed outside the frame after the wheel module 200 is removed, which makes the operation space more spacious and more convenient. After completing the maintenance operation, the user can push the new or maintained wheel module 200 into the frame 100 along the pull-out opening 101. The entire replacement process does not require professional tools or professional skills, and ordinary users can complete it completely by themselves. In some optional embodiments, to further facilitate the pulling and drawing operation of the wheel module 200, a handle (not shown in the figure) may be provided on the outside of the connecting frame 30. The provision of the handle can provide a better point of support for the user, making the pulling and drawing operation of the wheel module 200 more labor-saving and convenient. In this embodiment, the wheel 10 is arranged vertically, and the drawing opening 101 is provided on the side or top of the frame 100, which is convenient for operation.

[0028] In some embodiments, as Figure 2 、 Figure 3 As shown, the connecting frame 30 includes a main frame 31. The main frame 31 has a hollow structure. The side close to the wheel 10 is arc-shaped. The overall length is adapted to the width of the pull-out opening 101 and is slightly larger than the maximum outer diameter of the wheel 10, so as not to affect the operation of the wheel 10 while providing a stable support base; at the same time, the hollow structure forms a pull-out operating portion 311 suitable for human hand grasping at a position away from the center of the wheel 10. The main frame 31 adopts a hollow structure, so that the side of the main frame 31 away from the center of the wheel 10 directly forms a natural handle, that is, the pull-out operating portion 311 is formed on one side of the main frame 31, which allows the user to directly grasp the pull-out operating portion 311 for pulling and pulling operations without the need to install additional handles or other auxiliary structures on the connecting frame 30. In addition, the use of a hollow main frame 31 can effectively reduce its own weight while ensuring the structural strength of the connecting frame 30, thereby reducing the weight of the entire wheel module 200. In a specific example, as Figure 3 As shown, the main frame 31 is provided with an extension section 313 near the pull-out operating portion 311, and the extension section 313 extends toward the axis of the rotating wheel 10, which makes the position of the pull-out operating portion 311 have more space for human hands to reach in, and also enhances the structural strength of the main frame 31 with a hollow structure.

[0029] In some embodiments, as Figure 2 、 Figure 3 As shown, the direction perpendicular to the direction in which the wheel module 200 is drawn is the length direction of the main frame 31. The main frame 31 is provided with elastic snaps 312 on opposite sides of its length, and a latch hole 102 matching the elastic snaps 312 is provided in the drawer opening 101 of the frame 100. When the wheel module 200 is inserted into the drawer opening 101, the elastic snaps 312 engage with the latch holes 102 to secure the position of the wheel module 200. During the insertion of the wheel module 200, the elastic snaps 312 automatically deform upon contact with the latch holes 102, and automatically rebound and snap into the latch holes after being fully inserted, achieving automatic engagement, thereby effectively preventing the wheel module 200 from accidentally slipping out of the drawer opening 101 due to vibration, tilting, etc. during use. When the wheel module 200 needs to be removed, it only needs to be pulled outward with a slight force to allow the elastic snaps 312 to overcome the engaging force and disengage from the latch holes, allowing it to be easily removed.

[0030] In some embodiments, as Figure 2 、 Figure 3 As shown, the connecting frame 30 also includes an extension arm 32 extending radially along the rotating wheel 10, and the extension arm 32 has relative proximal and distal ends, the proximal end of which is the end connected to the main frame 31, and the distal end of which is the end away from the main frame 31, and the rotating shaft assembly 20 is installed at the distal end of the extension arm 32; the extension arm 32 is constructed to slide with the slide groove 103 provided in the pull-out opening 101 to realize the insertion and extraction of the rotating wheel module 200, and the sliding cooperation between the extension arm 32 and the slide groove 103 can also play a guiding role.

[0031] In some embodiments, as Figure 3 、 Figure 4 As shown, the groove walls opposite to the slide groove 103 are respectively provided with a limit block 104, so that a limit groove is formed in the slide groove 103, and the limit block 104 is against the side of the extension arm 32 facing the rotating wheel 10, and a part of the two corresponding sides of the extension arm 32 is respectively inserted into the limit groove, so that the limit block 104 plays a role in limiting the axial movement of the extension arm 32 along the rotating wheel 10, thereby limiting the axial shaking of the rotating wheel module 100, and combined with the setting of the elastic buckle 312 and the clamping hole 102, after the rotating wheel module 100 is assembled on the frame 100, its rotating wheel 10 can maintain a stable state and is not easy to shake and cause the tooth jamming phenomenon. In a specific embodiment, as Figure 4As shown, a positioning protrusion 1031 is provided in the slide groove 103, and the positioning protrusion 1031 is located at the end of the moving path of the extension arm 32, and a notch (not shown in the figure) that is adapted to the shape of the positioning protrusion 1031 is opened at the far end of the extension arm 32. When the wheel module 200 is fully inserted into place along the slide groove 103, the end of the extension arm 32 away from the main frame 31, that is, the notch on the far end of the extension arm 32 will be inserted into the positioning protrusion 1031 to clearly define the insertion limit position of the wheel module 200. At this time, the user will obviously feel the increase in resistance in the process of pushing the wheel module 200 in. This tactile feedback clearly informs the user that the wheel module 200 has been installed in place, effectively avoiding the risk of improper installation or incorrect installation.

[0032] In some embodiments, as Figure 2 、 Figure 3 、 Figure 5 As shown, two extension arms 32 are relatively arranged, and the two extension arms 32 are respectively located on both sides of the axial direction of the runner 10, thereby realizing bilateral symmetrical support for the runner 10, so that the runner 10 is subjected to more balanced force during operation and runs more stably; the shaft assembly 20 includes a sleeve 21, a threaded fastener 22, a fixing sleeve 23 and an outer frame 24, and the runner 10 is detachably accommodated in the outer frame 24, and the sleeve 21 passes through the runner 10 and is arranged in the outer frame 24, that is, at the rotation axis of the runner 10, and one extension arm 32 passes through the sleeve 23 through the threaded fastener 22, and is threadedly matched with the fixing sleeve 23 on the other extension arm 32. The use of threaded fasteners 22 and fixing sleeves 23 for connection makes the assembly process between the shaft assembly 20 and the extension arm 32 very convenient. That is, the user only needs to separate the threaded fasteners 22 and the fixing sleeve 23 through a simple screwing operation, and then remove the fixing sleeve 23 from the outer frame 24 to release the restriction on the rotating wheel 10 and take out the rotating wheel 10, thereby improving the maintainability of the product.

[0033] Specifically, if Figure 3 As shown, a driving assembly is provided on the frame 100, which includes a driving motor fixed on the frame 100 and a driving wheel 105 rotatably mounted on the frame 100. The output shaft of the driving motor is connected to the driving wheel 105, and the driving wheel 105 extends into the drawing port 101 and engages with the gear ring 25 sleeved on the outer periphery of the rotating wheel 10, thereby driving the rotating wheel 10 to rotate.

[0034] In some embodiments, as Figure 2 、 Figure 3As shown, the extension arm 32 has a hollow structure. On one hand, this hollow structure effectively reduces material usage while ensuring sufficient strength and rigidity for the extension arm 32. This ensures that the extension arm 32 can withstand the load of the wheel 10 and the shaft assembly 20 while minimizing its own weight. On the other hand, the hollow structure reduces wind resistance. In one example, the cross-sectional area of the extension arm 32 gradually decreases from one end toward the distal end near the shaft assembly 20. This gradually decreasing cross-sectional area facilitates guidance during insertion of the extension arm 32.

[0035] In some embodiments, a retractable sealing cover (not shown) is provided at the drawer opening 101 of the frame 100. In practice, the sealing cover can be opened and closed in a variety of ways, such as flip-top, push-pull, and rotary. Once the wheel module 200 is fully inserted, the sealing cover seals the drawer opening 101, preventing unexpected leakage and intrusion while also enhancing the dehumidifier's appearance.

[0036] In other embodiments, the rotor 10 is arranged horizontally, with the drawer opening 101 located on the side of the frame 100. The dehumidifier also includes a plate heat exchanger arranged obliquely below the rotor 10, with the water outlet of the plate heat exchanger located at a low, inclined position. The horizontal arrangement of the rotor 10 significantly reduces the overall height of the dehumidifier, making it suitable for installations with height constraints. The oblique arrangement of the plate heat exchanger, with its water outlet located at a low position, facilitates the smooth drainage of condensed water by gravity, preventing water accumulation.

[0037] The dehumidifier with replaceable wheels provided in this embodiment assembles the wheel, shaft assembly and connecting frame into a wheel module that can be pulled out along the frame, thereby realizing convenient removal and installation of the wheel. When necessary maintenance is required, there is no need to disassemble the dehumidifier frame and other internal components, which greatly simplifies the replacement and maintenance operations of the wheel. Ordinary users can complete it by themselves without professional tools and skills, effectively reducing the user's long-term use cost and extending the service life of the dehumidifier, ultimately bringing users a more economical, convenient and sustainable dehumidification experience.
