Description

Technical Field

[0001] The present application belongs to the technical field of air dehumidification equipment, and in particular, relates to a rotary dehumidifier with a convenient rotary wheel cleaning function. Background Art

[0002] The structure of the rotary dehumidifier mainly includes: casing, rotor, motor, electric heater, and two fans. The casing is divided into a dehumidification zone and a regeneration zone, each of which corresponds to one of the above fans.

[0003] The general principle of the rotary dehumidifier is: humid air passes through the rotor, the hygroscopic material on the rotor intercepts moisture, and then dry air is obtained, and the regenerated air is first heated and then blown through the rotor, taking away the moisture on it, so that the hygroscopic material can be reused, ensuring that the rotary dehumidifier continues to have a dehumidification effect.

[0004] Generally, the regenerated air is outdoor air, and the dehumidified air is also discharged to the outside. On the other hand, the wheel structure will accumulate dust and breed bacteria during long-term use, so it needs to be taken out and cleaned regularly.

[0005] For example, the Chinese utility model patent with authorization announcement number CN220793311U and authorization announcement date 2024.04.16 discloses a rotary dehumidifier that is easy to clean the rotary wheel. Its structural components mainly include: support blocks, baffles, screws, bearings, sealing gaskets, box bodies, batteries, alarms, bumps, grooves, top frames, bottom frames, belts, and dehumidification wheels.

[0006] The rotary dehumidifier in this utility model patent has the following advantages: compared with the existing overall disassembly and cleaning method, its cleaning structure facilitates the cleaning of the rotary wheel and greatly reduces the time required for a single cleaning of the rotary wheel.

[0007] However, the rotary dehumidifier still has at least the following impractical problems in the actual cleaning process, which are specifically manifested as follows:

[0008] The motor and dehumidifier wheel structure are connected together by an integral frame. Therefore, when the dehumidifier wheel is taken out for cleaning, the motor must be taken out together. This is very troublesome and dangerous. The motor is prone to many accidents such as falling, bumping, water ingress, wire breaking, etc., which greatly reduces its practicality and safety. Summary of the invention

[0009] The present application provides a rotary dehumidifier with a rotary wheel convenient cleaning function, and the technical problem to be solved is: how to make the removal and cleaning operation of the rotary wheel more convenient and safer.

[0010] The technical solution adopted by this application to solve the above problems is as follows: A rotary dehumidifier with a convenient cleaning function for the rotating wheel, the structure includes a rotating wheel and a driving motor, and further includes a bottom shell unit for installing the driving motor inside, a partition frame unit arranged on the inner side surface of the bottom shell unit, a driving ring unit arranged on the partition frame unit and used for circumferentially clamping the rotating wheel, and a cover plate unit arranged on the bottom shell unit and the partition frame unit.

[0011] A further preferred technical solution lies in that: The bottom shell unit includes a bottom plate for installing the driving motor and the partition frame unit, an annular side plate arranged on the bottom plate and used for connecting the cover plate unit, and an upstream air flow baffle arranged on the bottom plate and used for dividing the dehumidification area and the regeneration area.

[0012] A further preferred technical solution lies in that: The partition frame unit includes a partition arranged on the bottom plate, connected to the annular side plate and used for installing the rotating wheel, and an arc-shaped opening arranged on the partition and used for inserting and clamping the driving ring unit.

[0013] A further preferred technical solution lies in that: The driving ring unit includes a driven circular ring arranged on the arc-shaped opening, and the inner and outer annular surfaces are respectively used for connecting the rotating wheel and the driving motor.

[0014] A further preferred technical solution lies in that: The cover plate unit includes a detachable cover plate arranged on the annular side plate and the partition, and a downstream air flow baffle arranged on the inner side surface of the detachable cover plate and used for butting against the upstream air flow baffle.

[0015] A further preferred technical solution lies in that: The number of the partitions is 2, which are respectively used for separating the driving motor and the rotating wheel, and the operation panel and the rotating wheel.

[0016] A further preferred technical solution lies in that: The partition frame unit further includes a sealing and supporting dual-purpose frame body arranged on one of the partitions and connected to the annular side plate, and a motor shaft jack arranged on the sealing and supporting dual-purpose frame body.

[0017] A further preferred technical solution lies in that: The partition frame unit further includes a sealing shell arranged on the other partition, covering the arc-shaped opening and used for installing the operation panel.

[0018] A further preferred technical solution lies in that: The driving ring unit further includes an annular groove arranged on the end face of the driven circular ring; the partition frame unit further includes a support rod arranged on the arc-shaped opening and inserted into the annular groove.

[0019] A further preferred technical solution is that: the cover plate unit further includes a clamping plate disposed on the inner side surface of the detachable cover plate and used for docking the downstream air flow baffle and the upstream air flow baffle by clamping the partition plate and circumferentially positioning the detachable cover plate in this way.

[0020] The beneficial effects of this application include at least the following 4 points.

[0021] First, between the runner and the drive ring unit, there is sufficient circumferential clamping, and they can slide relative to each other simply and conveniently in the axial direction, ensuring the effective rotation dehumidification function, and the operation of taking out the runner for cleaning is convenient and fast. Correspondingly, the cover plate unit is set to be detachable.

[0022] Second, the operating area of the runner has sufficient and appropriate airtightness to prevent the driving motor and the operation panel from being damaged due to overheating.

[0023] Third, there is also a sufficient blocking effect between the dehumidification area and the regeneration area, ensuring the high efficiency of the electric heater and preventing a large amount of moisture from being carried in the dry air.

[0024] Fourth, the self-structure of the rotary dehumidifier has good stability and high compactness, and the disassembly and assembly operations are convenient and accurate. Brief Description of the Drawings

[0043] The following is only a preferred embodiment of this application, and does not limit the scope of this application.

[0044] As Figures 1-11 shown, a rotary dehumidifier with a convenient cleaning function for the rotating wheel, the structure includes a rotating wheel 11, and a driving motor 12, and further includes a bottom shell unit 1 for installing the driving motor 12 inside, a partition frame unit 2 arranged on the inner side surface of the bottom shell unit 1, a driving ring unit 3 arranged on the partition frame unit 2 and used for circumferentially engaging the rotating wheel 11, and a cover plate unit 4 arranged on the bottom shell unit 1 and the partition frame unit 2.

[0045] In this embodiment, the way for the dehumidifier to achieve the basic rotating wheel dehumidification function is as follows: The bottom shell unit 1 and the cover plate unit 4 together form the outer shell structure of the rotary dehumidifier. This outer shell has high airtightness, and there are 2 air holes on both of its two side surfaces, corresponding to the dry air and dehumidified air on one side, and the regeneration air and humid air on the other side. Finally, the inside of this outer shell is divided into a dehumidification area and a regeneration area, and each position on the rotating wheel 11 alternately passes between the dehumidification area and the regeneration area, thereby achieving a continuous dehumidification effect.

[0046] The reason why this rotary wheel dehumidifier has the function of facilitating the cleaning of the rotary wheel is as follows:

[0047] First, the rotary wheel 11 is not in direct contact with the driving motor 12. Instead, the driving ring unit 3 provides a continuous and effective power input function, greatly reducing the difficulty of removing and reinstalling the rotary wheel 11.

[0048] Second, only a sufficient circumferential clamping effect needs to be provided between the rotary wheel 11 and the driving ring unit 3, and there is no need for a large limiting relationship between them axially, so that the rotary wheel 11 can be relatively easily pulled out and removed from the driving ring unit 3.

[0049] Third, the cover plate unit 4 is screwed to the bottom shell unit 1 and can be disassembled separately, further improving the convenience of the rotary wheel cleaning operation.

[0050] Fourth, the positions of the rotary wheel 11 and the partition frame unit 2 are staggered from each other, and the partition frame unit 2 does not block the disassembly and assembly operations of the rotary wheel 11.

[0051] Among them, the main materials of the bottom shell unit 1, the partition frame unit 2, the driving ring unit 3, and the cover plate unit 4 are all engineering plastics. This rotary wheel dehumidifier can be used vertically or horizontally. When it is used horizontally, the cover plate unit 4 is on the top and the bottom shell unit 1 is on the bottom. And a dehumidifier housing structure can be provided outside the bottom shell unit 1 and the cover plate unit 4, or these two can directly serve as the equipment housing.

[0052] The bottom shell unit 1 includes a bottom plate 101 for installing the driving motor 12 and the partition frame unit 2, an annular side plate 102 provided on the bottom plate 101 and used for connecting the cover plate unit 4, and an upstream air flow baffle 103 provided on the bottom plate 101 and used for dividing the dehumidification area and the regeneration area.

[0053] In this embodiment, the bottom plate 101 is circular in shape, the annular side plate 102 is circular in shape, and the upstream air flow baffle 103 is in a "V" shape, and the three are integrally formed.

[0054] Among them, axially of the rotary wheel 11, the upstream air flow baffle 103 is fully and appropriately close to it, ensuring sufficient airtightness between the dehumidification area and the regeneration area, and at the same time, the upstream air flow baffle 103 cannot rub the rotary wheel 11 significantly. For example, the distance between their opposing surfaces can be set to 0.5 cm.

[0055] The partition frame unit 2 includes a partition 201 disposed on the bottom plate 101, connecting the annular side plate 102, and for installing the runner 11, and an arc-shaped opening 202 disposed on the partition 201 and for inserting and engaging the drive ring unit 3.

[0056] In this embodiment, the side surface of the partition 201 is flush with the annular side plate 102, so that the cover unit 4 can simultaneously abut against the partition 201 and the annular side plate 102, avoiding a harmful and completely preventable air leakage problem between the cover unit 4 and the partition 201.

[0057] Wherein, two arc-shaped surfaces of the arc-shaped opening 202 are attached to the outer ring surface of the drive ring unit 3, and the remaining two flat surfaces of the former are attached to the two end surfaces of the drive ring unit 3. Thus, it is achieved that:

[0058] First, the partition 201 can stably support the drive ring unit 3;

[0059] Second, a part of the outer ring surface of the drive ring unit 3 passes through the arc-shaped opening 202 and is exposed, providing a necessary structural basis for the driving operation of the drive motor 12.

[0060] Correspondingly, at this time, the partition 201 can separate the runner operation area and the motor installation area. Otherwise, if the drive motor 12 is located in the runner operation area, it will not only interfere with the rotation action of the runner 11, but also cause harmful heat exchange with the dehumidification area and the regeneration area. The latter includes:

[0061] 1. The relatively hot regeneration air blows the drive motor 12, which is likely to cause thermal damage to it;

[0062] 2. The heat generated by the drive motor 12 itself will not be transferred to the dehumidification area. Otherwise, the moisture adsorbed by the moisture-absorbing material will return to the dry air again, reducing the drying efficiency.

[0063] The drive ring unit 3 includes a driven ring 301 disposed on the arc-shaped opening 202, and the inner and outer ring surfaces are respectively used to connect the runner 11 and the drive motor 12.

[0064] In this embodiment, the axial thickness of the driven ring 301 is smaller than that of the runner 11, so that the upstream air flow baffle 103 can be close to the runner 11. And the radial thickness of the driven ring 301 is relatively large, avoiding the partition 201 from being knocked when the runner 11 is installed on and removed from the driven ring 301. For details, please refer to the appendix Figure 6 .

[0065] On the other hand, if the driving wheel 6 is a gear, a corresponding tooth structure is provided on the outer ring surface of the driven ring 301. If the driving wheel 6 is a rubber wheel, a corresponding rubber ring structure can be provided on the outer ring surface of the driven ring 301 to ensure sufficient frictional force between the two.

[0066] The cover plate unit 4 includes a detachable cover plate 401 provided on the annular side plate 102 and the partition plate 201, and a downstream air flow resistance partition plate 402 provided on the inner side surface of the detachable cover plate 401 and used for butting against the upstream air flow resistance partition plate 103.

[0067] In this embodiment, the detachable cover plate 401 is circular in shape, and is screwed to the annular side plate 102 and abuts against the partition plate 201. The projected shapes of the downstream air flow resistance partition plate 402 and the upstream air flow resistance partition plate 103 on the runner 11 coincide, ensuring sufficient isolation between the dehumidifying air flow and the regeneration air flow.

[0068] Similarly, the downstream air flow resistance partition plate 402 is also sufficiently and appropriately close to the runner 11, and the former cannot rub the latter during rotation.

[0069] On the other hand, the central angle corresponding to the "V-shaped" structure of the upstream air flow resistance partition plate 103 and the downstream air flow resistance partition plate 402 can be set to be larger or smaller, that is, the respective areas of the dehumidifying area and the regeneration area can be flexibly selected during the production of this dehumidifier. Generally, if the humidity of the working environment of this dehumidifier is relatively high, the central angle of the "V-shaped" structure is set to be relatively large, so as to obtain a larger regeneration area.

[0070] Correspondingly, the radially outer end of the upstream air flow resistance partition plate 103 can be provided on the partition plate 201 or the annular side plate 102. The former corresponds to a smaller area of the regeneration area, and specific reference can be made to the appendix Figure 2 The latter corresponds to a larger area of the regeneration area, and specific reference can be made to the appendix Figure 9 .

[0071] The number of the air holes 104 is 2, which are respectively located inside and outside the upstream air flow resistance partition plate 103. The inner hole corresponds to the regeneration air, and an extension pipe 15 and an electric heater 14 are installed thereon. The outer hole corresponds to the humid air, and an air inlet grille 16 is installed thereon.

[0072] The number of the partition plates 201 is 2, which are respectively used to separate the driving motor 12 and the runner 11, and the operation panel 13 and the runner 11.

[0073] In this embodiment, the basic functions of the two partitions 201 are the same, both for separating the electrified equipment from the runner operation area, and the above-mentioned electrified equipment refers to the drive motor 12 and the operation panel 13.

[0074] On the other hand, the additional functions of the two partitions 201 include: strengthening the installation of the runner 11 and strengthening the overall shell structure of the runner dehumidifier.

[0075] The partition frame unit 2 further includes a sealing and supporting dual-purpose frame 203 provided on one of the partitions 201 and connected to the annular side plate 102, and a motor shaft insertion hole 204 provided on the sealing and supporting dual-purpose frame 203.

[0076] In this embodiment, the functions of the sealing and supporting dual-purpose frame 203 combined with the motor shaft insertion hole 204 at least include:

[0077] First, since the driven ring 301 needs to continuously pass through the arc-shaped opening 202, the airtightness at this place is relatively poor. After setting the sealing and supporting dual-purpose frame 203, the drive motor 12 and the runner operation area can be more fully separated, which is an effective protection for both.

[0078] Second, the sealing and supporting dual-purpose frame 203 directly supports the partition 201 itself, thereby strengthening the installation of the drive motor 12.

[0079] Among them, the shape of the sealing and supporting dual-purpose frame 203 is rectangular, the driving wheel 6 is located inside the sealing and supporting dual-purpose frame 203, and the drive motor 12 is located outside the sealing and supporting dual-purpose frame 203.

[0080] The partition frame unit 2 further includes a sealing housing 205 provided on the other partition 201, covering the arc-shaped opening 202, and used for installing the operation panel 13.

[0081] In this embodiment, the airtightness function of the sealing housing 205 is the same as that of the sealing and supporting dual-purpose frame 203. The sealing housing 205 can also be used as the installation position of the operation panel 13. Finally, an operation opening corresponding to the operation panel 13 is left on the annular side plate 102.

[0082] The drive ring unit 3 further includes an annular groove 302 provided on the end face of the driven ring 301; the partition frame unit 2 further includes a support rod 206 provided on the arc-shaped opening 202 and inserted into the annular groove 302.

[0083] In this embodiment, the support rod 206 is used in cooperation with the annular groove 302, so that the outer circumferential surface of the driven ring 301 does not need to rub against the arc surface of the arc-shaped opening 202, making the rotation of the runner 11 more labor-saving.

[0084] Correspondingly, rollers are further arranged on the support rod 206, and the rollers are clamped into the annular groove 302, which can further reduce the resistance of the rotation of the runner 11.

[0085] The cover plate unit 4 further includes a clamping plate 403 which is arranged on the inner side surface of the detachable cover plate 401 and circumferentially positions the detachable cover plate 401 by clamping the partition plate 201, so as to be used for docking the downstream air flow resistance partition plate 402 and the upstream air flow resistance partition plate 103.

[0086] In this embodiment, when the runner 11 is reinstalled after being cleaned, it is necessary to align the downstream air flow resistance partition plate 402 and the upstream air flow resistance partition plate 103. In this process, the clamping plate 403 clamps the partition plate 201, which can be used as the inspection position for the above alignment operation, and this is the function of the clamping plate 403.

[0087] Among them, the cross-sectional shape of the clamping plate 403 is U-shaped, or two single plates used in combination. The principles of the two are the same, and both simultaneously clamp the two side surfaces of the partition plate 201.

[0088] In addition, the clamping plate 403 can also assist in supporting the partition plate 201, which is particularly important when the dehumidifier is used vertically.

[0089] Among them, on the detachable cover plate 401, there is also one air hole on the inner side of the downstream air flow resistance partition plate 402 corresponding to the humid air, and one air hole on the outer side corresponding to the dry air. Two fans 17 can be respectively arranged on these two air holes.

[0090] The embodiments of the present application have been described in detail above with reference to the drawings, but the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the purpose of the present application. These are all non-creative modifications and are protected by the patent law as long as they are within the scope of the claims of the present application.
