Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a humidity regulating device and an air conditioner. Background Art

[0002] At present, most air conditioners on the market have a dehumidification function. However, in the cold and dry autumn and winter seasons, when the air conditioner is running in heating mode, the indoor environment needs to be humidified to improve the comfort of the indoor environment. Therefore, it is necessary to equip the air conditioner with a humidification module to humidify the indoor environment.

[0003] There is a device for humidity regulation in the related technology, which is characterized by comprising: a first channel, one end of which is connected to the indoor room, and the other end of which is connected to the outdoor room; a second channel, which is arranged side by side with the first channel; a moisture absorption turntable, including a first part located in the first channel and a second part located in the second channel; a first heating device, which is arranged in the first channel; a second heating device, which is arranged in the second channel, one of the first channel and the second channel conveys airflow to the indoor room, and the other exhausts airflow to the outdoor room, and humidification or dehumidification can be performed by switching the first heating device and the second heating device.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] The moisture absorption capacity of the moisture absorption turntable is limited. When humidification is performed by allowing both the moisture absorption airflow and the humidification airflow to pass through the moisture absorption turntable at a single time, the moisture absorption capacity of the moisture absorption turntable is poor, resulting in a poor humidification effect. Summary of the invention

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] The embodiments of the present disclosure provide a humidity regulating device and an air conditioner to improve the functional diversity of the air conditioner, improve the humidification effect, and thus improve the air supply comfort of the air conditioner.

[0008] In some embodiments, the humidity control device includes: a first flow channel, a second flow channel, a moisture absorption wheel and a heating unit. The first flow channel has a first air inlet end and a first air outlet end, both of which are connected to the outdoor environment; the second flow channel has a second air inlet end and a second air outlet end, the second air inlet end is connected to the outdoor environment, and the second air outlet end is connected to the indoor environment; the moisture absorption wheel is rotatably arranged, and the moisture absorption wheel is partially located in the first flow channel, and the remaining part is located in the second flow channel; the heating unit is fixedly arranged in the second flow channel; wherein the second air inlet end and the second air outlet end of the second flow channel are located on the same side of the axial direction of the moisture absorption wheel, and the heating unit is arranged opposite to the second air inlet end and the second air outlet end, and is located on the other side of the axial direction of the moisture absorption wheel.

[0009] In some embodiments, an air conditioner comprises: an outdoor unit, an indoor unit and the humidity control device of the above embodiment. The indoor unit has a return air outlet; the humidity control device of the above embodiment is arranged on one side of the outdoor unit, and the second air outlet end of the second flow channel is connected to the return air outlet.

[0010] The humidity control device and air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0011] When the air flow at normal temperature flows through the hygroscopic wheel, the moisture in the air flow will be absorbed, and when the heated air flow flows through the hygroscopic wheel that absorbs moisture, the moisture in the hygroscopic wheel will be released into the air flow. Utilizing this characteristic of the hygroscopic wheel, the hygroscopic wheel is rotatably arranged, and part of it is located in the first flow channel, and the rest of it is located in the second flow channel. The outdoor hygroscopic air flows into the first flow channel from the first air inlet end, and flows out to the outdoor environment again from the first air outlet end. When the air flow circulating in the first flow channel passes through the part of the hygroscopic wheel located in the first flow channel, the moisture in the air flow is absorbed, and the hygroscopic wheel continues to rotate to rotate the part that absorbs moisture into the second flow channel, and the outdoor humidified air flow flows into the second flow channel from the second air inlet end, and is blown out to the indoor environment from the second air outlet end. Since the second air inlet end and the second air outlet end are both on the same side of the axial direction of the hygroscopic wheel, and the heating part is located on the other side of the axial direction of the hygroscopic wheel, the outdoor humidified air flow passes through When the second air inlet end flows into the second flow channel, it first passes through the hygroscopic wheel to absorb moisture, then flows through the heating part to be heated into hot air flow, and the heated air flow passes through the hygroscopic wheel again to release the moisture absorbed by the hygroscopic wheel into the hot air flow, and flows out from the second air outlet end to the indoor environment with the hot air flow to complete humidification. The hygroscopic wheel is continuously rotated to perform a waterless humidification process of absorbing moisture in the outdoor environment and releasing it into the indoor environment. Moreover, the humidified air flow introduced from the outdoor environment passes through the hygroscopic wheel twice, thereby increasing the moisture absorption capacity of the hygroscopic wheel, thereby improving the humidification effect. The humidity regulating device is installed on the outdoor unit side for use, and the humidified air flow blown out from the second air outlet end of the second flow channel is directly blown into the return air port of the indoor unit, and is blown out from the indoor unit to the indoor environment after heat exchange, thereby performing temperature and humidity dual control on the indoor environment, so that the air conditioner has the function of waterless humidification during heating, thereby improving the functional diversity of the air conditioner, thereby improving the air supply comfort and meeting the needs of users.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0033] Combination Figure 1-9 As shown, an embodiment of the present disclosure provides a humidity regulating device, including: a first flow channel 100 , a second flow channel 200 , a moisture absorption wheel 300 and a heating part 400 . The first flow channel 100 has a first air inlet end 110 and a first air outlet end 120, both of which are connected to the outdoor environment; the second flow channel 200 has a second air inlet end 210 and a second air outlet end 220, the second air inlet end 210 is connected to the outdoor environment, and the second air outlet end 220 is connected to the indoor environment; the hygroscopic wheel 300 is rotatably arranged, and part of the hygroscopic wheel 300 is located in the first flow channel 100, and the rest of the hygroscopic wheel 300 is located in the second flow channel 200; the heating part 400 is fixedly arranged in the second flow channel 200; wherein, the second air inlet end 210 and the second air outlet end 220 of the second flow channel 200 are located on the same side of the hygroscopic wheel 300 in the axial direction, and the heating part 400 is arranged opposite to the second air inlet end 210 and the second air outlet end 220, and is located on the other side of the hygroscopic wheel 300 in the axial direction.

[0034] In the humidity regulating device provided by the embodiment of the present disclosure, the moisture absorption wheel 300 is rotatably arranged, and part of it is located in the first flow channel 100, and the rest of it is located in the second flow channel 200. The outdoor moisture absorption air flows into the first flow channel 100 from the first air inlet end 110, and flows out to the outdoor environment again from the first air outlet end 120. When the airflow circulating in the first flow channel 100 passes through the part of the moisture absorption wheel 300 located in the first flow channel 100, the moisture in the airflow is absorbed, and the moisture absorption wheel 300 continues to rotate to rotate the part that absorbs moisture into the second flow channel 200. The outdoor humidified airflow flows into the second flow channel 200 from the second air inlet end 210, and is blown out to the indoor environment from the second air outlet end 220. Since the second air inlet end 210 and the second air outlet end 220 are both in the moisture absorption wheel The heating part 400 is located on the same side of the hygroscopic wheel 300 in the axial direction, and the heating part 400 is located on the other side of the hygroscopic wheel 300 in the axial direction. Therefore, when the outdoor humidified air flow flows into the second flow channel 200 through the second air inlet end 210, it first passes through the hygroscopic wheel 300 to absorb moisture, and then flows through the heating part 400 to be heated into hot air flow. The heated air flow passes through the hygroscopic wheel 300 again to release the moisture absorbed by the hygroscopic wheel 300 into the hot air flow, and flows out from the second air outlet end 220 to the indoor environment with the hot air flow to complete the humidification. The hygroscopic wheel 300 is continuously rotated to perform a waterless humidification process of absorbing moisture in the outdoor environment and releasing it into the indoor environment. In addition, the humidified air flow introduced into the outdoor environment is passed through the hygroscopic wheel 300 twice, so that the moisture absorption capacity of the hygroscopic wheel 300 is increased, thereby improving the humidification effect.

[0035] Optionally, the hygroscopic wheel 300 includes: a frame and a hygroscopic material. The frame is in a disc shape; the hygroscopic material is filled in the frame. In this way, the strength of the hygroscopic wheel 300 can be enhanced. The hygroscopic material is filled in the frame, and when the airflow passes through the frame, the moisture in the airflow is absorbed by the hygroscopic material filled in the frame, or the absorbed moisture in the hygroscopic material is released into the airflow, thereby better absorbing moisture from the outdoor environment to humidify the indoor environment.

[0036] Specifically, the frame is made of glass fiber or ceramic fiber material. In this way, the weight of the moisture absorption wheel 300 is reduced while ensuring the strength of the frame, which facilitates the installation and driving of the moisture absorption wheel 300.

[0037] Specifically, the hygroscopic material includes one or more of silica gel, MOF, and molecular sieve. Thus, one or more of the above materials can efficiently absorb moisture in the airflow at room temperature, and can efficiently release moisture when heated.

[0038] In some embodiments, the humidity control device further includes: a housing 500. The housing 500 defines a first flow channel 100 and a second flow channel 200, and the moisture absorption wheel 300 is rotatably disposed in the housing 500. Thus, the housing 500 is used to define the first flow channel 100 and the second flow channel 200, and the moisture absorption wheel 300 is rotatably installed in the housing 500, thereby improving the rotation stability of the moisture absorption wheel 300, thereby improving the stability of humidification.

[0039] Optionally, the housing 500 includes: an annular portion 510 and a semicircular portion 520. The moisture absorption wheel 300 is rotatably installed in the annular portion 510, and the axis of the moisture absorption wheel 300 coincides with the axis of the annular portion 510; the semicircular portion 520 is covered on the upper end surface of the annular portion 510, and the center of the semicircular portion 520 is located on the axis of the annular portion 510, the semicircular portion 520 is connected to the annular portion 510, the first flow channel 100 is defined by the inside of the annular portion 510, and the second flow channel 200 is defined by the inside of the annular portion 510 and the semicircular portion 520. In this way, the cover shell 500 is divided into an annular portion 510 and a semicircular portion 520. The annular portion 510 can better adapt to the installation of the hygroscopic wheel 300. The annular portion 510 and the semicircular portion 520 cooperate to define the second flow channel 200, so that the airflow in the second flow channel 200 is heated after passing through the hygroscopic wheel 300 for the first time, flows in the semicircular portion 520 and passes through the hygroscopic wheel 300 again to release moisture into the airflow. The humidified airflow can be absorbed by the hygroscopic wheel 300 before being heated, thereby increasing the moisture absorption capacity of the hygroscopic wheel 300 and thus improving the humidification effect.

[0040] Specifically, the heating part 400 is fixedly arranged in the semicircular part 520. In this way, since the moisture absorption wheel 300 is installed in the annular part 510, and the semicircular part 520 is covered on the upper end surface of the annular part 510, the semicircular part 520 is located on the upper end surface of the moisture absorption wheel 300 in the axial direction. Since the second air inlet end 210 and the second air outlet end 220 are located on the same side of the moisture absorption wheel 300 in the axial direction, the airflow passes through the moisture absorption wheel 300 in the axial direction of the moisture absorption wheel 300. The heating part 400 is fixedly arranged in the semicircular part 520, so that the humidified airflow in the second flow channel 200 can flow in the semicircular part 520 after passing through the moisture absorption wheel 300 for the first time, and after flowing in the semicircular part 520 and being heated, it passes through the moisture absorption wheel 300 again and flows out from the second air outlet end 220. The position of the heating part 400 is reasonably set.

[0041] Specifically, the heating part 400 divides the interior of the semicircular part 520 into two airflow chambers. In this way, the air intake and air output in the semicircular part 520 are matched, so that the air intake and air output of the second flow channel 200 are matched. Since the airflow that has passed through the moisture absorption wheel 300 and has been humidified can pass through the heating part 400 and be heated, the interior of the semicircular part 520 is evenly divided by the heating part 400, which can improve the heating effect of the humidified airflow.

[0042] Specifically, the moisture absorbing wheel 300 blocks the flow surface of the annular portion 510. In this way, the airflow flowing in the first flow channel 100 and the second flow channel 200 can completely pass through the moisture absorbing wheel 300 to be absorbed or humidified, thereby increasing the moisture absorption and humidification amount, thereby improving the humidification effect.

[0043] Optionally, a partition plate 511 is provided in the upper area inside the annular portion 510. The partition plate 511 is arranged along the radial direction of the annular portion 510 and passes through the axis of the annular portion 510. Both ends of the partition plate 511 extend to the inner annular walls opposite to each other of the annular portion 510 respectively. The hygroscopic wheel 300 is installed on the lower side of the partition plate 511. The first flow channel 100 is located on one side of the partition plate 511, and the second flow channel 200 is located on the other side of the partition plate 511. In this way, in order to ensure the rotation stability of the hygroscopic wheel 300, there is a reserved space between the upper end surface of the hygroscopic wheel 300 and the annular portion 510 after the hygroscopic wheel 300 is installed. In order to prevent the airflows in the first flow channel 100 and the second flow channel 200 from flowing into each other, a partition plate 511 is arranged in the annular portion 510 to divide the upper area inside the annular portion 510 into two parts, so that the airflows in the first flow channel 100 and the second flow channel 200 will not flow into each other after passing through the hygroscopic wheel 300, thereby ensuring that the hygroscopic in the first flow channel 100 and the humidification in the second flow channel 200 are carried out normally.

[0044] Combination Figure 3 and Figure 4As shown, in some embodiments, a partition assembly 530 is provided at the lower end of the housing 500 along the axial direction of the moisture absorption wheel 300, and the partition assembly 530 separates the lower end surface of the housing 500 into a first air inlet end 110, a second air inlet end 210 and a second air outlet end 220. In this way, by arranging a partition assembly 530 at the lower end of the cover shell 500, the first air inlet end 110, the second air inlet end 210 and the second air outlet end 220 are separated at the lower end surface of the cover shell 500, thereby avoiding interference between the air inlet of the first flow channel 100 and the air inlet and air outlet of the second flow channel 200. Moreover, since the heating part 400 and the second air inlet end 210 and the second air outlet end 220 are relatively arranged at the upper end of the axial direction of the hygroscopic wheel 300, the humidified air flow flowing in through the second air inlet end 210 passes upward through the hygroscopic wheel 300, then flows through the heating part 400 to be heated, and then passes downward through the hygroscopic wheel 300 again and flows out from the second air outlet end 220. When the heated humidified air flow passes through the hygroscopic wheel 300, the moisture absorbed by the hygroscopic wheel 300 is released into the airflow to form humid air. The gravity of the humid air is relatively large, and it sinks to the second air outlet end 220 for blowing out under the action of gravity, thereby improving the humidification effect.

[0045] Specifically, the moisture absorption wheel 300 is installed between the partition plate 511 and the partition assembly 530, the partition plate 511 is located at the upper end surface of the moisture absorption wheel 300, and the partition assembly 530 is located at the lower end surface of the moisture absorption wheel 300. In this way, the first flow channel 100 and the second flow channel 200 are separated by the inner wall of the housing 500, the partition plate 511 and the partition assembly 530, so that the airflow in the first flow channel 100 and the second flow channel 200 is prevented from flowing in series when passing through the moisture absorption wheel 300, thereby improving the stability of humidification and moisture absorption.

[0046] Specifically, the baffle assembly 530 is arranged on the lower end surface of the annular portion 510, and the lower end surface of the annular portion 510 is separated into the first air inlet end 110, the second air inlet end 210 and the second air outlet end 220. In this way, since the housing 500 is composed of the annular portion 510 and the semicircular portion 520, the moisture absorption wheel 300 is installed in the annular portion 510, and the heating portion 400 is installed in the semicircular portion 520, the baffle assembly 530 is arranged on the lower end surface of the annular portion 510, so that the inlet airflow of the first air inlet end 110 and the second air inlet end 210 can pass through the moisture absorption wheel 300, and the airflow in the second flow channel 200 can be heated by the heating portion 400 when passing through the moisture absorption wheel 300 and flowing into the semicircular portion 520 for the first time, and the heated airflow can pass through the moisture absorption wheel 300 again and flow out from the second air outlet end 220.

[0047] Optionally, the partition assembly 530 includes: an axial support 531, a first partition 532 and a second partition 533. The axial support 531 is arranged on the lower end surface of the housing 500 and is located on the axis of the moisture absorption wheel 300; the first partition 532 is divided into a first section 532-1 and a second section 532-2, the first section 532-1 and the second section 532-2 are respectively arranged on the outer walls on both sides of the axial support 531, and the first section 532-1 and the second section 532-2 are located on the same straight line, and are respectively connected to the inner walls on both sides of the lower end of the housing 500; the second partition 533 is arranged on the outer wall of the axial support 531, and is arranged perpendicular to the first partition 532, one end of the second partition 533 is connected to the outer wall of the axial support 531, and the other end is connected to the inner wall of the lower end of the housing 500. In this way, the axial support 531 can be used to support the installation of the moisture absorption wheel 300, and the first section 532-1 and the second section 532-2 of the first partition plate 532 cooperate with the axial support 531 to separate the air inlet area of ​​the first flow channel 100 and the air inlet and outlet area of ​​the second flow channel 200 at the lower end surface of the cover 500. The second partition plate 533 vertically arranged with the first partition plate 532 is used to separate the air inlet and outlet area of ​​the second flow channel 200 into a second air inlet end 210 and a second air outlet end 220, so that the air inlet of the first flow channel 100 and the air inlet and outlet of the second flow channel 200 do not interfere with each other, thereby improving the stability of moisture absorption and humidification. In addition, since the axial support 531 is located at the moisture absorption wheel 30 0, the lower end surface of the cover shell 500 is evenly divided by the cooperation of the first partition plate 532 and the axial support 531, the air inlet area of ​​the first flow channel 100 and the air inlet and outlet areas of the second flow channel 200 each occupy one half of the area of ​​the lower end surface of the cover shell 500, and the second partition plate 533 divides the air inlet and outlet areas of the second flow channel 200 into a second air inlet end 210 and a second air outlet end 220. Therefore, the hygroscopic airflow passing through the hygroscopic wheel 300 is the airflow flowing into the first air inlet end 110 of the first flow channel 100 and the second air inlet end 210 of the second flow channel 200. The hygroscopic area of ​​the hygroscopic wheel 300 is three times the area of ​​the humidification area, thereby increasing the moisture absorption amount and further improving the humidification effect.

[0048] Specifically, the first partition plate 532 is arranged in parallel with the partition plate 511 and is located in the same vertical plane in the vertical direction; the second partition plate 533 is arranged in parallel with the heating part 400 and is located in the same vertical plane in the vertical direction. In this way, the first partition plate 532, the partition plate 511 and the inner wall of the housing 500 cooperate to better define the first flow channel 100 and the second flow channel 200, and avoid the cross-flow of the airflows flowing in the first flow channel 100 and the second flow channel 200. In addition, the second partition plate 533 is arranged in parallel with the heating part 400, and the second flow channel 200 is divided into two parts, namely, the air inlet and the air outlet, both of which pass through the moisture absorption wheel 300. The airflow flowing in from the second air inlet end 210 flows into a side area of ​​the heating part 400 when passing through the moisture absorption wheel 300 for the first time, and then flows into the other side area of ​​the heating part 400 after passing through the heating part 400 to be heated. The heated airflow passes through the moisture absorption wheel 300 again and is blown out from the second air outlet end 220.

[0049] Optionally, a movable annular mounting frame 534 is provided in the housing 500, and the annular mounting frame 534 is rotatably arranged on the upper side of the axial support 531, and the moisture absorption wheel 300 is fixedly arranged in the annular mounting frame 534. In this way, the moisture absorption wheel 300 is fixedly installed by arranging the annular mounting frame 534, and the annular mounting frame 534 is supported by the axial support 531, and the annular mounting frame 534 is driven to continuously rotate on the axial support 531, thereby driving the moisture absorption wheel 300 to continuously rotate in the housing 500, so that the moisture absorption area and the humidification area of ​​the moisture absorption wheel 300 are continuously switched, and the moisture in the outdoor environment is absorbed and released to the indoor environment for humidification, thereby improving the rotation stability of the moisture absorption wheel 300.

[0050] Specifically, the annular mounting frame 534 is disposed in the annular portion 510, and the axial support 531 is located at the lower end surface of the annular portion 510. Thus, since the moisture absorption wheel 300 is mounted in the annular portion 510, the axial support 531 is disposed at the lower end surface of the annular portion 510, and the annular mounting frame 534 is disposed on the upper side of the axial support 531, so as to facilitate the installation and support of the moisture absorption wheel 300.

[0051] Optionally, an annular rack 535 is provided on the outer peripheral wall of the annular mounting frame 534, a motor support seat 536 is provided on the outer peripheral wall of the annular portion 510, a driving motor 537 is provided on the motor support seat 536, and an output end of the driving motor 537 is meshed and connected with the annular rack 535. In this way, the annular mounting frame 534 is driven to rotate by a driving mode in which the output end of the driving motor 537 is meshed with the annular rack 535, thereby driving the moisture absorption wheel 300 to rotate, which can improve the rotation stability of the moisture absorption wheel 300.

[0052] Optionally, the outer peripheral wall of the annular portion 510 is further provided with a motor cover 538, and the drive motor 537 is located in the motor cover 538, and the motor cover 538 is connected to the motor support seat 536 by screws. In this way, the motor cover 538 and the motor support seat 536 cooperate to support and protect the drive motor 537, thereby preventing the drive motor 537 from being exposed to the air.

[0053] Optionally, the first air outlet 120 is disposed on the upper end surface of the housing 500 along the axial direction of the moisture absorption wheel 300. In this way, since the first air inlet 110 is disposed on the lower end surface of the housing 500 along the axial direction of the moisture absorption wheel 300, in order to ensure the smooth flow of the moisture absorption airflow in the first flow channel 100, the first air outlet 120 is disposed on the upper end surface of the housing 500, and the airflow flowing into the first flow channel 100 from the first air inlet 110 can vertically pass through the moisture absorption wheel 300 and then flow out from the first air outlet 120, and the airflow does not need to change the flow direction, and the flow smoothness is good.

[0054] Specifically, the first air outlet 120 is disposed on the upper end surface of the annular portion 510. In this way, since the first flow channel 100 is defined by the annular portion 510, the first air outlet 120 is disposed on the upper end surface of the annular portion 510, and the moisture-absorbing airflow flowing in the first flow channel 100 is blown out from the upper end surface of the annular portion 510 after passing through the moisture-absorbing wheel 300 and being moisture-absorbed, so as to avoid the airflow blown out of the first flow channel 100 affecting the humidified airflow in the semicircular portion 520.

[0055] Combination Figure 5 As shown, in some embodiments, the heating unit 400 includes: a mounting frame 410 and a heating wire 420. The mounting frame 410 is fixedly arranged in the second flow channel 200 and blocks the flow surface of the second flow channel 200. The inner side of the mounting frame 410 has a flow opening 411; the heating wire 420 is arranged in the flow opening 411. In this way, the flow surface of the second flow channel 200 is blocked by the mounting frame 410, so that the airflow flowing in the second flow channel 200 needs to flow through the flow opening 411 inside the mounting frame 410, so as to fully contact with the heating wire 420 in the flow opening 411, thereby improving the heating effect of the airflow, and the heated airflow passes through the moisture absorption wheel 300 again to release the moisture absorbed by the moisture absorption wheel 300 into the airflow, thereby improving the humidification effect.

[0056] Specifically, the installation frame 410 is fixedly arranged in the semicircular portion 520, and the installation frame 410 is arranged along the radial direction of the moisture absorption wheel 300, and the installation frame 410 and the second partition plate 533 are in the same vertical plane. In this way, the airflow flowing in from the second air inlet end 210 reaches one side of the installation frame 410 after passing through the moisture absorption wheel 300, and the airflow circulates in the second flow channel 200 and needs to pass through the flow port 411 of the installation frame 410 to reach the other side of the installation frame 410, so that the electric heating wire 420 in the installation frame 410 is used to humidify the airflow.

[0057] In one embodiment, Figure 6 As shown, the leeward side of the installation frame 410 is provided with an air volume adjustment unit 430, which can adjust the excess air volume of the installation frame 410. In this way, the opening state of the air volume adjustment unit 430 can be adjusted according to the humidification demand, thereby adjusting the excess air volume of the installation frame 410 to better meet the humidification demand.

[0058] Optionally, the air volume adjustment unit 430 includes: a mounting rail 431, a first adjustment plate 432, and a second adjustment plate 433. There are two mounting rails 431, and the two mounting rails 431 are respectively arranged at the upper and lower edges of the leeward side of the mounting frame 410, and the first adjustment plate 432 and the second adjustment plate 433 are both slidably arranged between the two mounting rails 431, and the first adjustment plate 432 and the second adjustment plate 433 are limited to slide in opposite or opposite directions between the two mounting rails 431 to adjust the air volume of the mounting frame 410. In this way, by respectively arranging a mounting rail 431 at the upper and lower edges of the leeward side of the mounting frame 410, arranging the slidable first adjustment plate 432 and the second adjustment plate 433 in the two mounting rails 431, the air volume of the mounting frame 410 is adjusted by sliding the first adjustment plate 432 and the second adjustment plate 433 in opposite or opposite directions, so as to accurately adjust the air volume of the mounting frame 410 according to the humidification demand.

[0059] Specifically, when the first adjustment plate 432 and the second adjustment plate 433 are driven to slide toward each other, the overwind volume of the installation frame 410 is gradually reduced; when the first adjustment plate 432 and the second adjustment plate 433 are driven to slide in opposite directions, the overwind volume of the installation frame 410 is gradually increased. In this way, when the air in the outdoor environment is relatively dry, if the original overwind volume of the installation frame 410 is maintained, the humidification air volume may be large, and the moisture absorbed by the moisture absorption wheel 300 cannot meet the current humidification air volume, resulting in poor humidification effect and low humidity of the air flow blown into the room. Therefore, the first adjustment plate 432 and the second adjustment plate 433 are driven to slide toward each other to reduce the overwind volume of the installation frame 410, that is, reduce the humidification air volume, and improve the user's humidification experience. When the air humidity in the outdoor environment is better, the desiccant wheel 300 fully absorbs the moisture in the outdoor air and can meet a larger humidification air volume. Therefore, the first adjustment plate 432 and the second adjustment plate 433 are driven to slide back to back, so that the air volume of the mounting frame 410 is relatively increased, thereby increasing the humidification air volume. The moisture absorbed by the desiccant wheel 300 is released into a large amount of humidification airflow, and is blown into the room with the humidified airflow, thereby better meeting the user's humidification needs.

[0060] Optionally, a first motor 434 and a second motor 435 are provided on the lower side of the mounting track 431 located below, and racks are provided on the lower edges of the first adjustment plate 432 and the second adjustment plate 433. The output end of the first motor 434 passes through the mounting track 431 and is meshed with the rack of the first adjustment plate 432, and the output end of the second motor 435 passes through the mounting track 431 and is meshed with the rack of the second adjustment plate 433. In this way, the first motor 434 is used to drive the first adjustment plate 432 to slide, and the second motor 435 is used to drive the second adjustment plate 433 to slide, so as to more accurately adjust the excess air volume of the mounting frame 410 according to the humidification demand.

[0061] Combination Figure 7 and Figure 8 As shown, in some embodiments, the humidity control device further includes: a first air duct 600 and a second air duct 700. The first air duct 600 is arranged at one side of the first flow channel 100, and the air outlet end of the first air duct 600 is connected to the first air inlet end 110, the air inlet end of the first air duct 600 is provided with an air inlet 601, the air inlet 601 is connected to the outdoor environment, and a first fan 602 is arranged in the first air duct 600; the second air duct 700 is arranged at one side of the second flow channel 200, and the air inlet end of the second air duct 700 is connected to the second air outlet end 220, the air outlet end of the second air duct 700 is connected to the indoor environment, and a second fan 701 is arranged in the second air duct 700. In this way, by setting the first air duct 600 and the second air duct 700 to be connected with the first flow channel 100 and the second flow channel 200 respectively, the hygroscopic airflow in the outdoor environment flows into the first air duct 600 through the air inlet 601 of the first air duct 600, and then flows into the first flow channel 100 from the first air inlet end 110. The hygroscopic airflow flowing into the first flow channel 100 passes through the hygroscopic rotor 300, and the moisture in the airflow is adsorbed by the hygroscopic rotor 300. The hygroscopic airflow flows into the outdoor environment again through the first air outlet end 120. The negative pressure required for the circulation of the hygroscopic airflow in the first flow channel 100 is provided by the first fan 602. The humidified airflow in the outdoor environment passes through the first The second air inlet end 210 flows into the second flow channel 200. The humidified airflow flowing into the second flow channel 200 is heated when passing through the heating part 400. The heated airflow passes through the moisture absorption wheel 300 to release the absorbed moisture into the airflow. The humid airflow carrying moisture flows into the second flow channel 200 through the second air outlet end 220, and then is blown out into the indoor environment through the second flow channel 200. The second fan 701 is used to provide the negative pressure required for the circulation of the humidified airflow in the second flow channel 200. The setting of the first air duct 600 and the second air duct 700 facilitates the circulation of the hygroscopic airflow and the humidified airflow, so that the humidified airflow carrying moisture can flow more smoothly into the indoor environment for humidification.

[0062] Optionally, the first air duct 600 and the second air duct 700 are both arranged on the lower side of the annular portion 510 of the housing 500, and the first air duct 600 and the second air duct 700 are symmetrically distributed on both sides of the first partition plate 532. In this way, since the first partition plate 532 divides the lower end surface of the annular portion 510 into the air inlet area of ​​the first flow channel 100 and the air inlet and outlet areas of the second flow channel 200, the first air duct 600 and the second air duct 700 are both arranged on the lower side of the annular portion 510 and symmetrically distributed on both sides of the first partition plate 532, so that the first air duct 600 and the second air duct 700 are connected with the corresponding first flow channel 100 and the second flow channel 200 respectively.

[0063] Optionally, the first fan 602 and the second fan 701 are both centrifugal fans.

[0064] Specifically, the first air duct 600 includes: a first circulation part 610 and a first air collecting cover 620. The first circulation part 610 is arranged at the lower side of the first air collecting cover 620 and is connected to the first air collecting cover 620. The air outlet end of the first circulation part 610 is connected to the first air inlet end 110, the air inlet 601 is connected to the first air collecting cover 620, and the first fan 602 is arranged in the first circulation part 610, and the air inlet end of the first fan 602 is arranged toward the first air collecting cover 620. In this way, since the first fan 602 is a centrifugal fan with its air inlet end in the axial direction and its air outlet end in the radial direction, in order to reduce the space occupied by the installation of the first fan 602, the first air duct 600 is divided into a first circulation portion 610 and a first air collecting hood 620, and the first fan 602 is installed in the first circulation portion 610, with the air inlet end of the first fan 602 in the axial direction arranged toward the first air collecting hood 620. The negative pressure generated when the first fan 602 is running acts on the first air collecting hood 620, thereby sucking air from the outdoor environment into the first circulation portion 610 through the first air collecting hood 620. By installing the first fan 602 in the first circulation portion 610, the space occupied by the first fan 602 in the axial direction can be reduced, thereby reducing the thickness of the humidity regulating device along the axial direction of the first fan 602.

[0065] Specifically, the second air duct 700 includes: a second circulation part 710 and a second air collecting cover 720. The second circulation part 710 is arranged at the lower side of the second air collecting cover 720 and is connected to the second air collecting cover 720. The air inlet end of the second circulation part 710 is connected to the second air outlet end 220. The air outlet end of the second air collecting cover 720 is connected to the indoor environment. The second fan 701 is arranged in the second air collecting cover 720, and the air inlet end of the second fan 701 is arranged toward the second circulation part 710. In this way, since the second fan 701 is also a centrifugal fan, in order to reduce the space occupied by the second fan 701 during installation, the second air duct 700 is divided into a second circulation portion 710 and a second air collecting hood 720. Moreover, since the second air duct 700 is an air outlet channel, the second fan 701 is installed in the second air collecting hood 720, so that the air inlet end of the second fan 701 in the axial direction is arranged toward the second circulation portion 710. The negative pressure generated when the second fan 701 is in operation acts on the second circulation portion 710, thereby sucking in the humid air flow flowing out from the second air outlet end 220. Under the action of the second fan 701, the humid air flow in the second circulation portion 710 flows into the second air collecting hood 720, and then is blown into the indoor environment through the second air collecting hood 720. The method of installing the second fan 701 in the second air collecting hood 720 can reduce the space occupied by the second fan 701 in the axial direction, thereby reducing the thickness of the humidity regulating device along the axial direction of the second fan 701.

[0066] Specifically, the axes of the first fan 602 and the second fan 701 are both parallel to the axis of the annular portion 510 of the housing 500 .

[0067] Optionally, the outlet end of the second air duct 700 is provided with an outlet hose 702, and the outlet hose 702 is connected to the indoor environment. In this way, the outlet hose 702 has elasticity and ductility, can adapt to different installation environments, and is convenient for conveying the humid air flow blown out of the outlet end of the second air duct 700 to the indoor environment.

[0068] Specifically, the air outlet hose 702 is connected to the air outlet end of the second air collecting cover 720 .

[0069] Combination Fig. 9As shown, in some embodiments, the humidity regulating device further includes: a housing 800. The cover 500, the first air duct 600 and the second air duct 700 are all arranged in the housing 800, the air inlet 601 of the first air duct 600 is arranged on the left side wall of the housing 800, the air outlet hose 702 is arranged on the right side wall of the housing 800, the air outlet end of the second air duct 700 passes through the right side wall of the housing 800 and communicates with the air outlet hose 702, and the rear side wall of the housing 800 is provided with an air outlet 810 corresponding to the first air outlet end 120 and an air suction port 820 corresponding to the second air inlet end 210. In this way, the setting of the shell 800 facilitates the installation and use of the humidity regulating device. The shell 800 protects the cover 500, the first air duct 600 and the second air duct 700 to prevent the cover 500, the first air duct 600 and the second air duct 700 from being exposed to the outdoor environment. The hygroscopic airflow in the outdoor environment flows into the first air duct 600 through the air inlet 601, and then enters the first flow channel 100 to absorb moisture. The airflow after moisture absorption flows out through the first air outlet end 120 and then flows out to the outdoor environment again through the exhaust port 810. The second air inlet end 210 of the second flow channel 200 inhales the humidified airflow from the outdoor environment through the air suction port 820. The humidified humid airflow flows into the second air duct 700 from the second air outlet end 220, and then flows out to the air outlet hose 702 through the air outlet end of the second air duct 700, and finally flows into the indoor environment through the air outlet hose 702.

[0070] Combination Fig.10 As shown, in some embodiments, an air conditioner includes: an outdoor unit 900, an indoor unit 910 and the humidity control device of the above embodiment.

[0072] Optionally, the housing 800 is arranged outside the outdoor unit 900, the second air outlet end 220 of the second flow channel 200 is connected to the air inlet end of the second air channel 700, and the air outlet end of the second air channel 700 is connected to the return air port 911 of the indoor unit 910 through the air outlet hose 702.

The cover plate 902 of the outdoor unit 900 is installed at the opening 830 at the upper end of the shell to close it. The shell of the humidity control device of the above embodiment does not need to be blocked during production, which saves costs. When there is no need to assemble the humidity control device of the above embodiment on the outdoor unit 900 side, the humidity control device of the above embodiment can be disassembled, and the installation port 903 at the upper end of the casing 901 can be closed by the cover plate 902.
