Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dehumidifiers, and particularly relates to a rotating installation structure of a rotating wheel and a dehumidifier. BACKGROUND

[0002] A rotating wheel dehumidifier is a commonly used air humidity adjusting device, and is widely applied to fields such as families, industries and commerce. The rotating wheel dehumidifier usually comprises a casing, an air duct arranged in the casing, a rotating wheel arranged in the air duct, a driving mechanism for driving the rotating wheel to rotate, and other components (such as a fan, a heater, a heat exchanger, etc.) for processing air. Air flows through the rotating wheel under the action of the fan, and the moisture-absorbing material on the rotating wheel adsorbs the moisture in the air, so that dehumidification is achieved.

[0003] However, in the long-term use process of the existing rotating wheel dehumidifier, the rotating wheel is prone to the following problems: firstly, since the rotating wheel dehumidifier usually operates in an air environment, the air inevitably contains particulate matters such as dust and impurities, which will enter the interior of the dehumidifier along with the air and gradually deposit in the honeycomb-shaped channels of the rotating wheel, causing the channels to be blocked, and the blocking of the channels will reduce the moisture-absorbing efficiency of the rotating wheel, directly leading to a decrease in dehumidification performance; secondly, in the working process of the rotating wheel dehumidifier, the rotating 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 deformation of the rotating wheel material, for example, deformation of the honeycomb channels and reduction of the opening, that is, deformation of the rotating wheel will also reduce the air flow efficiency and the moisture-absorbing area, further affecting the dehumidification effect.

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

[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 rotating wheel usually needs to be performed by professional maintenance personnel. It is difficult for ordinary users to complete the replacement by themselves, and the maintenance cost is high and the time consumption is long. INVENTION CONTENTS

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] Firstly, embodiments of this application provide a rotating mounting structure for a dehumidifier having an air handling duct 100. For example... Figures 1 to 3 As shown, the structure mainly includes a rotating shaft assembly 10 and a support arm 40. The outer frame 30 houses a dehumidifying wheel 20. The support arm 40 is typically mounted on the main structure of the dehumidifier and extends into the air handling duct 100, providing a rotatable mounting base for the outer frame 30 and the dehumidifying wheel 20, and facilitating easy replacement of the dehumidifying wheel 20. In this embodiment, the outer frame 30 is made of stainless steel.

[0026] Specifically, the rotating shaft assembly 10 includes a central fixing sleeve 11, a screw 12, and a nut 13; the dehumidifying wheel 20 is detachably housed within the outer frame 30 via the central fixing sleeve 11; the screw 12 passes through the central fixing sleeve 11 and one end of the support arm 40 and is adapted to connect with the nut 13 to rotatably fix the central fixing sleeve 11 and the outer frame 30 onto the support arm 40. This structural design allows the dehumidifying wheel 20 and the outer frame 30 to rotate freely relative to the support arm 40 as a whole around the axis of the central fixing sleeve 11, providing a basis for the normal operation of the rotary dehumidifier.

[0027] When necessary maintenance or replacement of the dehumidifying wheel 20 is required, simply loosen the screw 12 and remove the nut 13 to remove the central fixing sleeve 11, along with the outer frame 30 and the dehumidifying wheel 20, from the support arm 40. Since the central fixing sleeve 11 and the dehumidifying wheel 20 are detachably connected, the dehumidifying wheel 20 can be easily removed from the outer frame 30 for separate cleaning, inspection, or replacement, thus enabling convenient replacement and maintenance of the dehumidifying wheel 20.

[0028] In some embodiments, one end of the screw 12 away from the nut 13 and / or one end of the nut 13 away from the screw 12 is provided with a driving part 14 which is suitable for external tools or human hands to operate. The driving part 14 can be a slot head, a cross slot, an internal hexagonal hole, etc. of the screw head, or can be a hexagonal shape, knurling, etc. on the outer periphery of the nut 13. In actual application, the user can select appropriate tools (such as a slot screwdriver, a cross screwdriver, an internal hexagonal wrench, a socket wrench, etc.) or directly use hands to drive the screw 12 or the nut 13 according to the type of the driving part 14.

[0029] In some embodiments, as shown in Figure 2 , the central fixing sleeve 11 is provided at one axial end with a plurality of elastic buckles 111 which are arranged at intervals along the circumferential direction thereof, and the outer frame 30 is provided with a plurality of card holes 31 which correspond to the positions of the elastic buckles 111, the elastic buckles 111 being buckled in the card holes 31 so as to form a separable buckling connection between the central fixing sleeve 11 and the outer frame 30. In this embodiment, the central fixing sleeve 11 serves as a support component for realizing rotation of the rotating wheel, and is buckled with the outer frame 30 as a fixing component of the dehumidifying wheel 20. In actual assembly, the operator only needs to align the central fixing sleeve 11 with the outer frame 30 by passing the central fixing sleeve 11 through the dehumidifying wheel 20, and then presses it inward slightly so that the elastic buckles 111 on the central fixing sleeve 11 will slide into the card holes 31 on the outer frame 30 by virtue of their own elasticity, thereby completing a quick and stable buckling connection. Similarly, when it is necessary to separate the central fixing sleeve 11 from the outer frame 30, it is also unnecessary to use any tool, but only needs to bend the elastic buckles 111 so as to make them disengage from the card holes 31, and the disassembly operation is also convenient and efficient.

[0030] As shown in Figure 4 , the central fixing sleeve 11 comprises a head part 112 and a hollow shaft part 113, a plurality of elastic buckles 111 are uniformly and intervaliy arranged on the outer peripheral wall of the shaft part 113, and notches are formed on both sides of each elastic buckle 111. The head part 112 is an annular baffle structure arranged at one end of the shaft part 113, the hollow shaft part 113 provides space for cooperation of the screw 12 and the nut 13, and the notches formed on the outer peripheral wall of the shaft part 113 can accommodate the elastic buckles 111 to reduce the axial length of the entire central fixing sleeve 11.

[0031] In some embodiments, as shown in Figure 1 , Figure 2 , two support arms 40 are oppositely arranged, and the two support arms 40 are respectively located on the two axial sides of the dehumidifying wheel 20. In specific implementation, a through hole 41 for the screw 12 to pass through is formed at the end of each support arm 40. This double-side support design can provide more balanced support force, effectively prevent the dehumidifying wheel 20 from tilting or swinging during rotation, and improve the overall stability and carrying capacity of the rotating wheel assembly. Meanwhile, the through holes 41 on the two support arms also provide accurate positioning for installation of the screw 12 and the nut 13.

[0032] As shown in Figure 5 , the screw 12 includes a screw head and a screw rod, the nut 13 includes a nut head and a nut rod, the nut rod is provided with a threaded hole for screwing the screw rod, the nut rod passes through one of the support arms 40 and the outer frame 30 and extends into the center fixing sleeve 11, the screw rod passes through the other support arm 40 and extends into the center fixing sleeve 11 and is screwed with the nut rod, the nut head abuts against the outer side of one of the support arms 40 in the axial direction, and the screw head abuts against the outer side of the other support arm 40 in the axial direction. In this way, the screw 12 and the nut 13 are formed in a lock to provide stronger clamping force.

[0033] In some embodiments, as shown in Figure 2 , Figure 3 , the support arm 40 is a hollow structure, and the cross-sectional area of the support arm 40 gradually decreases from one end away from the rotating shaft assembly 10 to one end close to the rotating shaft assembly 10. On the one hand, the hollow structure effectively reduces the amount of material used under the premise of ensuring that the support arm 40 has sufficient strength and rigidity, thereby reducing the overall weight, and on the other hand, the design of the gradually decreasing cross-sectional area of the support arm 40 can effectively reduce the obstruction of the support arm 40 to the airflow passing through the dehumidification wheel 20, thereby reducing the wind resistance.

[0034] In some embodiments, as shown in Figure 2 , the outer frame 30 includes a center seat 32, a circular sleeve frame 33 concentrically arranged with the center seat 32, and a gear ring 34, the inner wall surface of the circular sleeve frame 33 is connected with the center seat 32 through a plurality of spokes 35, and the gear ring 34 is buckled with the circular sleeve frame 33 and forms a receiving space between the two, which is adapted to the dehumidification wheel 20. That is, the center seat 32, the circular sleeve frame 33 and the spokes 35 together constitute a stable frame structure, which can reliably support and fix the dehumidification wheel 20, and the plurality of spokes 35 are connected with the center seat 32 and the circular sleeve frame 33 in a radial manner. This structure has good anti-torsion and anti-bending ability, which can effectively prevent the outer frame 30 from deforming during use, and also reduces the obstruction of the support arm 40 to the airflow passing through the dehumidification wheel 20.

[0035] As shown in Figure 2 , Figure 5As shown, each of the sockets 31 is annularly spaced on the center seat 32, and the center fixing sleeve 11 is detachably connected to the center seat 32 by the cooperation of the elastic buckle 111 and the socket 31. Specifically, the center seat 32 is in a cylindrical shape, the dehumidification wheel 20 is sleeved on the outer peripheral wall of the center seat 32, and each of the sockets 31 is annularly spaced on the inner peripheral wall of the center seat 32. The inner diameter of the center seat 32 is slightly larger than the outer diameter of the rod portion 113 of the center fixing sleeve 11, so that when the elastic buckle 111 is inserted into the center seat 32 and buckled with the socket 31, the rod portion 113 can be sleeved with the center seat 32 to provide additional radial support, and at the same time, the head portion 112 of the fixing sleeve 11 abuts against the axial one-side end surface of the dehumidification wheel 20 to axially limit the dehumidification wheel 20.

[0036] In some embodiments, as shown in Figure 2 , Figure 3 As shown, the inner ring edge of the gear ring 34 is provided with a radially extending limiting flange 341 abutting against the circumferential edge of the dehumidification wheel 20. In the present embodiment, the main function of the limiting flange 341 is to limit the movement of the dehumidification wheel 20 in the axial direction to prevent the dehumidification wheel 20 from being unexpectedly detached from the outer frame 30.

[0037] In a second aspect, the embodiments of the present application provide a dehumidifier, which comprises the rotating installation structure of the rotating wheel of any one of the embodiments of the first aspect. The rotating installation structure of the rotating wheel constitutes a separate rotating wheel module 200, and the dehumidifier shell 50 is provided with a pull-out opening 51 for inserting and pulling out the rotating wheel module 200. In this way, the rotating installation structure of the rotating wheel constitutes a separate rotating wheel module 200, which does not need to be connected to other additional functional components such as heat exchangers, fans and heaters commonly used in dehumidifiers. When the rotating wheel needs to be maintained or replaced, the user can only pull out the entire rotating wheel module 200 from the dehumidifier through the pull-out opening 51 on the dehumidifier shell 50. Since the rotating wheel module 200 is independent, all maintenance operations (such as cleaning, inspection, replacement of the dehumidification wheel, etc.) can be performed outside the dehumidifier, and the operation space is wider, the operation process is more convenient and fast, and other components of the dehumidifier do not need to be disassembled, thereby significantly reducing the maintenance difficulty and time cost and improving the maintenance efficiency.

[0038] In some embodiments, as shown in Figure 3 The main body 60 is also provided, which is a drawer type installed in the pull-out opening 51, and the support arm 40 protrudes from the main body 60 in the axial direction of the dehumidification wheel 20. The inner wall of the pull-out opening 51 is provided with a sliding groove 52 in sliding cooperation with the support arm 40. In this way, the support arm 40 and the main body 60 jointly bear the weight of the rotating wheel module 200 and transmit it to the dehumidifier shell 50, ensuring stable assembly, and the sliding groove 52 can guide the main body 60 to be inserted and pulled out in the correct direction, preventing it from deviating or being stuck during the pulling-out process.

[0039] In some embodiments, as shown in Figure 3 The main body 60 has a hollow structure forming a pulling position 61 suitable for a human hand to hold. The hollow structure directly forms a natural handle, i.e., the pulling position 61, which allows a user to directly hold and pull the pulling position 61 without the need for additional installation of a handle or other auxiliary structure on the main body 60. In addition, the hollow main body 60 can effectively reduce its own weight while ensuring sufficient structural strength, thereby reducing the weight of the entire rotating wheel module 200.

[0040] The rotating installation structure of the rotating wheel and the dehumidifier provided by the embodiment adopts a detachable rotating shaft assembly design. The rotating shaft assembly is composed of a center fixing sleeve, a screw, and a nut. The center fixing sleeve is fixed on the support arm of the mounting frame through the cooperation of the screw and the nut, and the center fixing sleeve rotatably supports the dehumidifying wheel, achieving stable installation and convenient disassembly of the dehumidifying wheel. The entire process is simple and fast to operate, and does not require professional tools and skills. Ordinary users can independently complete the operation, avoiding the risk of equipment damage caused by complex disassembly and assembly operations, effectively prolonging the service life of the dehumidifier, and improving the user experience.
