Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air treatment equipment, and particularly relates to a rotary wheel replaceable dehumidifier. BACKGROUND

[0002] The rotary wheel dehumidifier is a commonly used air humidity adjusting equipment, and is widely applied to fields such as family, industry and commerce. The rotary wheel dehumidifier usually comprises a rack, an air duct arranged in the rack, a rotary wheel arranged in the air duct, a driving mechanism for driving the rotary wheel to rotate, and other components (such as a fan, a heater, a heat exchanger and the like) for processing air. Air flows through the rotary wheel under the action of the fan, and the moisture-absorbing material on the rotary wheel adsorbs the moisture in the air, so that dehumidification is realized.

[0003] However, in the long-term use process of the existing rotary wheel dehumidifier, the rotary wheel is prone to the following problems: firstly, since the rotary wheel dehumidifier usually operates in an air environment, dust, impurities and other particulate matters are inevitably contained in the air, which will enter the interior of the dehumidifier along with the air and gradually deposit in the honeycomb-shaped channels of the rotary wheel, causing the channels to be blocked, and the blocking of the channels will reduce the moisture-absorbing efficiency of the rotary wheel, directly leading to the decline of dehumidification performance; secondly, in the working process of the rotary wheel dehumidifier, the rotary wheel needs to be heated and regenerated to release the adsorbed moisture, and long-term high-temperature baking, especially in the case of inaccurate temperature control, is prone to cause the deformation of the rotary wheel material, for example, the deformation of the honeycomb channels and the reduction of the opening, that is, the deformation of the rotary wheel will also reduce the air flow efficiency and the moisture-absorbing area, further affecting the dehumidification effect.

[0004] Once the rotary wheel has problems such as blocking or deformation, the conventional method is generally to scrap the whole machine. If the rotary wheel is to be replaced, the operation is very cumbersome. In the existing structure of the rotary wheel dehumidifier, the rotary wheel is usually fixedly installed in the interior of the rack, and the replacement operation is extremely inconvenient. When replacing, the user needs to use a screwdriver and the like to disassemble the shell of the dehumidifier to access the internal space where the rotary wheel is located, and since the rotary wheel is usually closely connected with other functional modules (for example, a fan, a heater, an air duct and the like) of the dehumidifier, before disassembling the rotary wheel, the related components usually need to be dismounted first, so as to make space for the rotary wheel, for example, the processing air generating module and the regeneration air generating module connected with the rotary wheel module need to be dismounted.

[0005] Due to the cumbersome disassembly steps, the disassembly of multiple components is involved, and certain professional knowledge and operation skills are required, therefore, the replacement of the rotary wheel usually needs to be performed by professional maintenance personnel. It is difficult for ordinary users to complete the replacement by themselves, the maintenance cost is high, and the time consumption is long. INVENTION CONTENTS

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and 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 rotating wheel replaceable dehumidifier described in the present embodiment, likeFigures 1 to 4 The air duct is provided in the housing 100 of the dehumidifier, and the rotary wheel 10 is used to dehumidify the air flowing through the air duct. In a specific implementation, as shown in Figure 1 The air duct is provided in the housing 100 of the dehumidifier, and the rotary wheel 10 is used to dehumidify the air flowing through the air duct. In a specific implementation, as shown in

[0026] As shown in Figures 1 to 4 The dehumidifier further comprises a rotary shaft assembly 20 and a connecting frame 30, the rotary wheel 10 is rotatably installed on the connecting frame 30 through the rotary shaft assembly 20 to form a rotary wheel module 200, the housing 100 is provided with a pull-out opening 101 suitable for inserting and pulling out the rotary wheel module 200, the position and size of the pull-out opening 101 are matched with the rotary wheel module 200, and the rotary wheel module 200 is configured to be removably inserted and pulled out of the dehumidifier. In this way, the rotary wheel 10 is assembled with the connecting frame 30 through the rotary shaft assembly 20 to form a separate rotary wheel module 200, and the rotary wheel module 200 of the embodiment is designed as a separate component that can be removed from the dehumidifier, and the rotary wheel module 200 is not provided with other additional functional components such as the heat exchanger 40, the fan 50 and the heater 60, so that the dehumidifier is provided with the possibility of maintenance, and the production and use cost is reduced.

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

[0028] In some embodiments, as shown in Figure 2 , Figure 3 The connecting frame 30 includes a main frame 31, which has a hollow structure, and the side close to the rotary wheel 10 is arc-shaped. The overall length is adapted to the width of the pull opening 101 and slightly larger than the maximum outer diameter of the rotary wheel 10, so as to provide stable support without affecting the operation of the rotary wheel 10. At the same time, the hollow structure forms a pull operation part 311 suitable for human hand gripping at a position away from the center of the rotary 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 rotary wheel 10 directly forms a natural handle, that is, the main frame 31 forms the pull operation part 311 on one side, which enables the user to directly grip the pull operation part 311 for pulling operation without the need for additional installation of a handle or other auxiliary structure on the connecting frame 30. In addition, the 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 rotary wheel module 200. In a specific example, as shown in Figure 3 , the main frame 31 is provided with an extension segment 313 at a position close to the pull operation part 311, which extends towards the axis direction of the rotary wheel 10, which makes the position of the pull operation part 311 have more space for the human hand to stretch into, and also enhances the structural strength of the main frame 31 with a hollow structure.

[0029] In some embodiments, as shown inFigure 2 , Figure 3 As shown, the direction perpendicular to the pull-out direction of the rotary module 200 is the length direction of the main frame 31. The main frame 31 has elastic buckles 312 on opposite sides along its length. The pull-out opening 101 of the frame 100 has corresponding locking holes 102. When the rotary module 200 is inserted into the pull-out opening 101, the elastic buckles 312 engage with the locking holes 102 to fix the position of the rotary module 200. During insertion, the elastic buckles 312 automatically deform upon contact with the locking holes 102 and automatically spring back into the locking holes after full insertion, achieving automatic engagement. This effectively prevents the rotary module 200 from accidentally sliding out of the pull-out opening 101 due to vibration, tilting, or other reasons during use. When it is necessary to remove the rotary module 200, simply pull it outwards with slight force to allow the elastic buckles 312 to overcome the engaging force and disengage from the locking holes, allowing for easy removal.

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

[0031] In some embodiments, such as Figure 3 , Figure 4 As shown, limiting blocks 104 protrude from the opposite walls of the slide groove 103, thus forming limiting grooves in the slide groove 103. The limiting blocks 104 abut against the side of the extension arm 32 facing the wheel 10, and a portion of each side of the extension arm 32 is inserted into the limiting groove. Thus, the limiting blocks 104 restrict the axial movement of the extension arm 32 along the wheel 10, thereby limiting the axial sway of the wheel module 100. Combined with the elastic buckle 312 and the locking hole 102, the wheel module 100, after being assembled onto the frame 100, maintains a stable state, preventing swaying and tooth jamming. In a specific embodiment, as... Figure 4As shown, the chute 103 is provided with a positioning protrusion 1031 at the end of the moving path of the extension arm 32, and the distal end of the extension arm 32 is provided with a notch (not shown in the figure) matched with the shape of the positioning protrusion 1031. When the rotating wheel module 200 is fully inserted into the chute 103, the distal end of the extension arm 32, i.e. the notch on the distal end of the extension arm 32, will be inserted into the positioning protrusion 1031, so as to clearly define the insertion limit position of the rotating wheel module 200. At this time, the user will obviously feel an increase in resistance during the process of pushing the rotating wheel module 200, and this tactile feedback clearly informs the user that the rotating wheel module 200 has been installed in place, effectively avoiding the risk of improper installation or installation errors.

[0032] In some embodiments, as shown in Figure 2 、 Figure 3 、 Figure 5 As shown, two extension arms 32 are arranged oppositely, and the two extension arms 32 are respectively located on the two axial sides of the rotating wheel 10, achieving bilateral symmetrical support of the rotating wheel 10, so that the rotating wheel 10 is more balanced in force during operation and runs more stably. The rotating shaft assembly 20 includes a shaft sleeve 21, a threaded fastener 22, a fixing sleeve 23, and an outer frame 24. The rotating wheel 10 is detachably accommodated in the outer frame 24. The shaft sleeve 21 passes through the rotating wheel 10 and is arranged in the outer frame 24, i.e. at the rotating shaft center of the rotating wheel 10. One extension arm 32 passes through the shaft sleeve 23 through the threaded fastener 22, and is threadedly connected with the fixing sleeve 23 on the other extension arm 32. The threaded fastener 22 and the fixing sleeve 23 are connected, so that the assembly process between the rotating shaft assembly 20 and the extension arm 32 is very convenient. That is, the user only needs to separate the threaded fastener 22 and the fixing sleeve 23 through a simple screwing operation, and then remove the fixing sleeve 23 from the outer frame 24 to remove the restriction on the rotating wheel 10 and take out the rotating wheel 10. The product has good maintainability.

[0033] Specifically, as shown in Figure 3 The rack 100 is provided with a driving assembly, which includes a driving motor fixed on the rack 100 and a driving wheel 105 rotatably installed on the rack 100. The output shaft of the driving motor is connected with the driving wheel 105. The driving wheel 105 extends into the pull-out opening 101 and engages with the gear ring 25 sleeved on the outer periphery of the rotating wheel 10, so as to drive the rotating wheel 10 to rotate.

[0034] In some embodiments, as shown in Figure 2 、 Figure 3As shown, the extension arm 32 is a hollow structure. In one aspect, the hollow structure effectively reduces the amount of material used while ensuring that the extension arm 32 has sufficient strength and rigidity, and at the same time, maximizes the weight reduction of the extension arm 32 itself while ensuring that the extension arm 32 can withstand the load of the runner 10 and the shaft assembly 20. On the other hand, the hollow structure can reduce wind resistance. In one example, the cross-sectional area of the extension arm 32 gradually decreases from one end to the distal end near the shaft assembly 20. The structure with gradually decreasing cross-sectional area can facilitate the guidance of the extension arm 32 during insertion.

[0035] In some embodiments, a sealable cover (not shown in the figure) is arranged at the pull-out opening 101 of the rack 100. In specific implementation, the sealable cover can adopt various opening and closing modes, such as flip cover, push-pull, rotation, etc. When the runner module 200 is inserted in place, the sealable cover can close the pull-out opening 101 to avoid unintended leakage and intrusion, and also make the appearance of the dehumidifier more neat and beautiful.

[0036] In other embodiments, the runner 10 is arranged horizontally, and the pull-out opening 101 is arranged on the side of the rack 100; the dehumidifier further comprises a plate heat exchanger arranged obliquely below the runner 10, and the water outlet end of the plate heat exchanger is located at the low position of the inclination. The horizontally arranged runner 10 greatly reduces the overall height of the dehumidifier, which is suitable for scenarios where the installation space height is limited. The obliquely arranged plate heat exchanger has its water outlet end at the low position, which is beneficial for the smooth drainage of condensed water by gravity, and avoids water accumulation.

[0037] The runner-replaceable dehumidifier provided in the embodiments can realize convenient removal and insertion of the runner by assembling the runner, the shaft assembly, and the connecting frame into a runner module that can be pulled out along the rack. The replacement and maintenance operations of the runner are greatly simplified, and ordinary users can complete the operations by themselves without professional tools and skills, which effectively reduces the long-term use cost of the users, prolongs the service life of the dehumidifier, and ultimately brings the users a more economical, convenient, and sustainable dehumidifying experience.
