Description

Technical Field

[0001] The present application relates to the technical field of humidity regulation, for example, to a device for dehumidification. Background Art

[0002] At present, some commercial areas such as shopping malls or warehouses often have different requirements for the humidity of the internal air. However, the humidity in the indoor air fluctuates greatly with the change of seasons, so the humidity of the internal space needs to be adjusted.

[0003] In the related art, a dehumidifier is usually used to dehumidify the indoor environment. The fan of the dehumidifier draws wet air into the machine, and after dehumidification, dry air is discharged, thereby reducing the indoor humidity and gradually achieving a dry effect in the wet space. However, this dehumidification method does not thoroughly treat the water content of the airflow, so there is still a large amount of water content in the airflow entering the room, which reduces the dehumidification efficiency.

[0004] Therefore, how to dehumidify the air flow, make the gas discharged into the room drier, and improve the dehumidification efficiency has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] 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 elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0006] The embodiment of the present disclosure provides a device for dehumidification, which uses an evaporator to perform secondary dehumidification on the air flow, further reducing the water content of the air flow flowing into the room, maintaining the dryness of the gas discharged into the room, and thereby improving the dehumidification efficiency.

[0007] In some embodiments, a dehumidification device includes a housing, a moisture absorption assembly, and an evaporator. A first air duct and a second air duct are provided within the housing, wherein the first air duct includes a first air inlet and a first air outlet, both of which are connected to the outside of the room; the second air duct includes a second air inlet and a second air outlet, both of which are connected to the room; the moisture absorption assembly is disposed between the first and second air ducts and extends through them; and the evaporator is disposed between the second air outlet and the moisture absorption assembly.

[0008] The dehumidification device provided by the embodiments of the present disclosure can achieve the following technical effects:

[0009] By connecting the first air inlet end and the first air outlet end of the first air duct to the outdoors, the second air inlet end and the second air outlet end of the second air duct to the indoor, and arranging an evaporator between the second air outlet end and the desiccant component, the dehumidification device is put into an internal circulation dehumidification working state, so that the indoor air flow is sent into the desiccant component through the second air inlet end, and the moisture in the air flow is absorbed by the desiccant component. The air flow after the moisture is absorbed flows to the second air outlet end, and an evaporator is arranged between the second air outlet end and the desiccant component. Since the evaporator has a refrigeration effect, water vapor can condense when it is cooled, thereby achieving the dehumidification effect. Therefore, an evaporator is arranged at the first air outlet end, which can perform secondary dehumidification on the air flow after dehumidification by the desiccant component. Therefore, when the desiccant component is not completely dehumidified, the evaporator is used to perform secondary dehumidification on the air flow, further reducing the moisture content of the air flow flowing into the room, maintaining the dryness of the gas discharged into the room, and thereby improving the dehumidification efficiency.

[0039] Combine Figure 1-2 As shown, an embodiment of the present disclosure provides a dehumidification device, comprising: a housing 100, a moisture absorption component 400, and an evaporator 500. A first air duct 200 and a second air duct 300 are provided inside the housing 100, wherein the first air duct 200 includes a first air inlet end 201 and a first air outlet end 202, and both the first air inlet end 201 and the first air outlet end 202 are connected to the outside of the room; the second air duct 300 includes a second air inlet end 301 and a second air outlet end 302, and both the second air inlet end 301 and the second air outlet end 302 are connected to the room; the moisture absorption component 400 is disposed between the first air duct 200 and the second air duct 300, and passes through the first air duct 200 and the second air duct 300; the evaporator 500 is disposed between the second air outlet end 302 and the moisture absorption component 400.

[0040] The dehumidification device provided by the embodiment of the present disclosure is used, by connecting the first air inlet end 201 and the first air outlet end 202 of the first air duct 200 to the outside, and the second air inlet end 301 and the second air outlet end 302 of the second air duct 300 to the room, and arranging an evaporator 500 between the second air outlet end 302 and the moisture absorption component 400, so that the dehumidification device is in an internal circulation dehumidification working state, so that the indoor air flow is sent into the room through the second air inlet end 301 and flows to the moisture absorption component 400, and the moisture in the air flow is absorbed by the moisture absorption component 400, and the air flow after the moisture is absorbed flows to the second air outlet end 302. There are two air outlet ends 302, and an evaporator 500 is arranged between the second air outlet end 302 and the dehumidification component 400. Since the evaporator 500 has a refrigeration effect, water vapor can condense when it is cooled, thereby achieving a dehumidification effect. Therefore, the evaporator 500 is arranged at the first air outlet end 202, which can perform secondary dehumidification on the air flow after dehumidification by the dehumidification component 400. In this way, when the dehumidification of the dehumidification component 400 is not thorough, the evaporator 500 is used to perform secondary dehumidification on the air flow, further reducing the water content of the air flow flowing into the room, maintaining the dryness of the gas discharged into the room, and thereby improving the dehumidification efficiency.

[0041] Optionally, a pair of clamping grooves 600 are provided on the inner side wall of the second air outlet end 302, and the two ends of the evaporator 500 are respectively disposed in a clamping groove 600. Thus, by arranging the evaporator 500 in the clamping grooves 600, it is not only easier to fix the evaporator 500, but also it can prevent the evaporator 500 from being displaced by the air flow, ensuring that the evaporator 500 can stably heat the airflow passing through the evaporator 500. In addition, it is more convenient to install and remove the evaporator 500, and it is convenient to disassemble, repair, and replace the evaporator 500.

[0042] Optionally, a line connecting the pair of clamping grooves 600 and the direction of airflow passing through the evaporator 500 forms a set angle, and the set angle is greater than or equal to 45° and less than or equal to 135°. Thus, the evaporator 500, mounted within the clamping grooves 600, and the direction of airflow passing through the evaporator 500 also form a set angle. That is, the evaporator 500 is tilted relative to the direction of airflow, and the set angle is set between greater than or equal to 45° and less than or equal to 135°, keeping the set angle within a reasonable range. As airflow flows toward the tilted evaporator 500, the contact area between the airflow and the evaporator 500 is increased, allowing the airflow at the air outlet to be fully dehumidified by the evaporator 500. This lowers the moisture content of the airflow discharged into the room, making the airflow into the room drier and maintaining the dryness of the air discharged into the room, thereby improving dehumidification efficiency. Furthermore, the tilted arrangement reduces wind resistance, allowing airflow through the evaporator 500 to flow more rapidly, thereby increasing airflow velocity.

[0043] Optionally, the evaporator 500 is connected to the compressor of the indoor air conditioner. In this way, the compressor of the air conditioner is used to generate cold energy, which is energy-saving, environmentally friendly, and reduces costs.

[0044] Optionally, a switch valve is provided on the evaporator 500, which can be controlled to open or close the evaporator 500. In this way, the evaporator 500 can be opened or closed according to different working conditions to prevent affecting the normal operation of the dehumidification.

[0045] Optionally, a first heating mechanism 203 is provided in the first air inlet end 201 , a second heating mechanism 303 is provided in the second air inlet end 301 , a first fan 204 is provided in the first air outlet end 202 , and a second fan 304 is provided in the second air outlet end 302 . In this way, by providing a first heating mechanism 203 in the first air inlet end 201 and a second heating mechanism 303 in the second air inlet end 301, the airflow can be heated first and then the heated airflow passes through the dehumidification component 400. The heated airflow is used to heat the dehumidification component 400 in the dehumidification device, and then the moisture therein is regenerated. When performing internal circulation dehumidification indoors, the moisture in the dehumidification component 400 can be regenerated by heating the outdoor wind, which is convenient for the subsequent continued dehumidification of the indoor airflow and dehumidification operation. A first fan 204 is provided in the first air outlet end 202 and a second fan 304 is provided in the second air outlet end 302, which can drive the airflow circulation and increase the airflow flow speed. Since the first heating mechanism 203 and the second heating mechanism 303 both need to be provided at the air inlet end, the airflow is first heated and then passed through the dehumidification component 400. Therefore, the fan is provided at the air outlet end to avoid the fan and the heating mechanism being installed in adjacent positions, which will affect each other and reduce their respective service lives, making the installation structure more reasonable.

[0046] Optionally, the first heating mechanism 203 and the second heating mechanism 303 have the same structure. Taking the first heating mechanism 203 as an example, the first heating mechanism 203 is a rectangular frame structure with multiple mica electric heating plates evenly spaced along its width. Air channels are provided between adjacent mica electric heating plates. This allows the airflow passing through the first heating mechanism 203 to be heated more evenly, reduces wind resistance, and facilitates airflow, thereby achieving better dehumidification.

[0047] Optionally, a baffle 700 is provided between the first air inlet 201 and the first air outlet 202, as well as between the second air inlet 301 and the second air outlet 302. Thus, the baffle 700 divides the air duct into an air inlet and an air outlet, making the airflow in and out more stable. After entering the air inlet, the airflow flows toward the moisture absorption assembly 400. After dehumidifying the airflow, the moisture absorption assembly 400 flows toward the air outlet, where the evaporator 500 within the air outlet performs secondary dehumidification. This prevents cross-flow of the airflow during flow, reduces the stability of the airflow, and prevents the airflow from being discharged directly from the air outlet without passing through the moisture absorption assembly 400, thereby improving dehumidification efficiency.

[0048] Optionally, one of the pair of clamping grooves 600 is provided on the baffle plate 700, and the other is provided on the inner sidewall of the air outlet, with the pair of clamping grooves 600 being centrally symmetrically arranged. This facilitates installation of the evaporator 500, with the ends of the evaporator 500 connected to the baffle plate 700 and the inner sidewall of the air outlet, respectively, so that the evaporator 500 is in a state of separating the air outlet. This allows the airflow in the air outlet to pass through the evaporator 500 as it flows toward the air outlet, and the airflow is fully dehumidified by the evaporator 500, thereby improving dehumidification efficiency.

[0049] Optionally, the line connecting the clamping groove 600 on the baffle plate 700 and the clamping groove 600 on the inner sidewall of the air outlet is perpendicular to the inner sidewall of the air outlet. This allows the evaporator 500, which is located within the pair of clamping grooves 600, to be positioned perpendicular to the inner sidewall of the air outlet, making the installation of the evaporator 500 more secure and improving the stability of the evaporator 500. As the air flows through the evaporator 500, the evaporator 500 will not shift in position, thereby allowing the airflow to be stably dehumidified by the evaporator 500.

[0050] Optionally, the clamping groove 600 has a U-shaped opening, and the evaporator 500 is clamped in the U-shaped opening. In this way, the evaporator 500 can be fixed in the U-shaped opening, which is not only convenient for installing the evaporator 500, but also more stable.

[0051] like Figure 3-7As shown, in some optional embodiments, the moisture absorption assembly 400 includes: a housing 401, a sealed partition 402, a first humidity conditioning block 405, and a second humidity conditioning block 406. The sealed partition 402 is disposed within the housing 401, dividing the interior of the housing 401 into a first channel 403 and a second channel 404; the first humidity conditioning block 405 is disposed within the first channel 403, dividing the first channel 403 into a first zone 407 and a second zone 408; the second humidity conditioning block 406 is disposed within the second channel 404, dividing the second channel 404 into a third zone 409 and a fourth zone 410; wherein the first zone 407, the second zone 408, the third zone 409, and the fourth zone 410 are all provided with vents 411 that can be controlled to open or close. In this way, the interior of the shell 401 is separated into a first channel 403 and a second channel 404 by using a sealed partition 402, and a humidity control block is provided in the first channel 403 and the second channel 404. When the airflow passes through the humidity control block, the moisture in the airflow will be absorbed by the humidity control block, so that the exhaust has a dehumidification effect, and when the heated airflow passes through the humidity control block, the moisture in the humidity control block will be regenerated, so that the exhaust has a humidification effect. By controlling the opening of different vents 411, the airflow and the heated airflow are alternately passed through the first channel 403 and the second channel 404, so that the exhaust can be continuously cooled. Humidification or dehumidification is continuously performed, and by controlling the opening of different vents 411, the indoor air flow and the outdoor air flow can be exchanged or not exchanged during the humidification or dehumidification process, and then the indoor air flow and the outdoor air flow are exchanged when there is a need for indoor ventilation, and the indoor air flow and the outdoor air flow are not exchanged when the outdoor air quality is poor and there is no need for ventilation, thereby avoiding outdoor polluted air from entering the room, selectively utilizing the outdoor air flow, reducing dependence on the outdoor environment, improving the stability of humidity regulation, and maintaining the quality of indoor air.

[0052] Optionally, a switch assembly 412 is provided on the vent 411, which can close or open the vent 411. In this way, the vent 411 can be opened or closed by the switch assembly 412 provided on the vent 411. Different air flow paths can be achieved by opening different vents 411, thereby performing internal circulation humidification and dehumidification, as well as external circulation humidification and dehumidification. Outdoor airflow can be selectively utilized according to different needs, reducing dependence on the outdoor environment, improving the stability of humidity regulation, and maintaining indoor air quality.

[0053] Optionally, the switch assembly 412 includes a closing baffle 413 and a drive motor 414. One side of the closing baffle 413 is rotatably connected to a side of the vent 411 via a rotating shaft. The drive motor 414 is fixed to the housing 401, and its output shaft 439 is connected to the rotating shaft. The drive motor 414 is capable of rotating the closing baffle 413, such that the closing baffle 413 closes the vent 411 in a first position and opens the vent 411 in a second position. Thus, the vent 411 is opened or closed by the structure of the closing baffle 413, which is simple and easy to implement. Furthermore, the space occupied by the closing baffle 413 during installation can be reduced, making the structure more compact.

[0054] Optionally, a sealing ring is provided around the circumference of the vent 411 and / or the circumference of the closed baffle 413. In this way, the sealing effect when the vent 411 is closed can be improved to prevent air leakage and reduce the efficiency of humidification or dehumidification.

[0055] Optionally, the sealing baffle 402 is horizontally disposed within the housing 401, such that the first and second channels 403 and 404 are arranged parallel to each other. The sealing baffle 413 can be rotated to open toward the side of the vent 411 near the edge of the housing 401, and when in the second position, a predetermined angle is formed between the sealing baffle 413 and the vent 411. Thus, since the opened vent 411 is disposed on one side of the middle of the first or second channel 403 or 404, the airflow on the other side of the first or second channel 403 or 404 is less. When the sealing baffle 413 opens the vent 411, a predetermined angle is formed between the sealing baffle 413 and the vent 411, allowing the sealing baffle 413 to have a certain flow-guiding effect, distributing the airflow more evenly through the first and second channels 403 and 404, thereby improving the uniformity of the airflow and, in turn, allowing the airflow to pass more evenly through the first and second humidity control blocks 405 and 406, thereby improving the efficiency of humidification or dehumidification.

[0056] Optionally, the first humidity control block 405 and the second humidity control block 406 are both rotatable relative to the housing 401 at an angle of 90 degrees. Thus, when there is no need for indoor ventilation, the different vents 411 are controlled to open, so that air entering from the outside passes through the first channel 403 and is then discharged outdoors through the vents 411 on the same side. Similarly, air passing through the room passes through the second channel 404 and is then discharged back into the room through the vents 411 on the same side. By controlling the rotation of the first humidity control block 405 and the second humidity control block 406, their positions are changed, allowing the first humidity control block 405 and the second humidity control block 406 to always straddle the airflow path, allowing air to fully pass through the first humidity control block 405 and the second humidity control block 406, thereby improving the efficiency of moisture absorption and moisture regeneration, and thereby improving the efficiency of humidifying or dehumidifying the air.

[0057] Optionally, the first humidity control block 405 and the second humidity control block 406 have the same structure, each comprising a frame and a hygroscopic material. The frame is rectangular, and the hygroscopic material is filled within the frame. This improves the structural stability of the humidity control blocks (the first humidity control block 405 and the second humidity control block 406 may be collectively referred to as the humidity control blocks) and prevents damage to the blocks.

[0058] Optionally, the skeleton is made of glass fiber or ceramic fiber. In this way, the structure is stable and light, which facilitates the rotation of the first humidity control block 405 and the second humidity control block 406.

[0059] Optionally, the moisture absorbing material includes one or more of silica gel and molecular sieve, so that the moisture in the airflow can be efficiently absorbed and the moisture can be efficiently released under heating, thereby improving the efficiency of humidification or dehumidification.

[0060] Optionally, the moisture absorbing assembly 400 further includes a drive mechanism 415. The drive mechanism 415 is connected to both the first humidity control block 405 and the second humidity control block 406 and is capable of driving the first humidity control block 405 and the second humidity control block 406 to rotate. Thus, the drive mechanism 415 drives the first humidity control block 405 and the second humidity control block 406, facilitating control of their movement and better controlling their positions.

[0061] Optionally, the drive mechanism 415 includes a motor and a drive shaft. The drive shaft is connected to the output terminal of the motor and fixedly connected to the first humidity control block 405 and the second humidity control block 406. This allows the motor to drive the first humidity control block 405 and the second humidity control block 406 to rotate synchronously, simplifying the drive structure, ensuring stable operation, and reducing costs.

[0062] Optionally, the centers of the first humidity control block 405 and the second humidity control block 406 are located on the same vertical line, and the drive shaft is located on the vertical line and passes through one of the first humidity control block 405 and the second humidity control block 406 and connects to the other. In this way, by driving the center positions of the first humidity control block 405 and the second humidity control block 406, the rotation stability of the first humidity control block 405 and the second humidity control block 406 is improved.

[0063] Optionally, the centers of the first humidity control block 405 and the second humidity control block 406 are located on the same vertical line, and the first humidity control block 405 and the second humidity control block 406 are fixedly connected via a fixed shaft, and the drive shaft is connected to the first humidity control block 405 or the second humidity control block 406. In this way, the first humidity control block 405 and the second humidity control block 406 are fixedly connected, and when one is driven to rotate, the other can rotate synchronously with it, which can simplify the drive structure, make operation more stable, and reduce costs.

[0064] Optionally, a perforation is provided at the center of the sealing partition 402 to allow a drive shaft or a fixed shaft to pass through, thereby facilitating the connection between the first humidity control block 405 and the second humidity control block 406, simplifying the installation structure, and allowing the first humidity control block 405 and the second humidity control block 406 to rotate synchronously.

[0065] Optionally, a sealing bearing is provided in the perforation. In this way, the sealing effect of the sealing partition 402 can be maintained to prevent the airflows on both sides from mixing and affecting the efficiency of humidification or dehumidification.

[0066] In some embodiments, the dehumidification device is in an internal circulation dehumidification condition. Outdoor air enters from the first air inlet end 201, passes through the first heating mechanism 203, and then enters the first channel 403 through the upper vent 411 near the first air inlet end 201. It passes through the first humidity control block 405 in the first channel 403, regenerates the moisture in the first humidity control block 405, and then enters the first air outlet end 202 through the upper vent 411 near the first air outlet end 202. The air is discharged to the outdoors from the first air outlet end 202 to reduce the indoor humidity; the indoor air enters from the second air inlet end 301 and then passes through the lower vent 411 near the second air inlet end 301. The air enters the second channel 404 and passes through the second humidity control block 406 in the second channel 404. After the moisture in the air flow is absorbed by the second humidity control block 406, the air flow enters the second air outlet 302 through the vent 411 close to the second air outlet 302. The evaporator 500 is set in the second air outlet 302, which can perform secondary dehumidification on the air flow after dehumidification by the dehumidification component 400. Therefore, when the dehumidification of the dehumidification component 400 is not complete, the evaporator 500 is used to perform secondary dehumidification on the air flow, further reducing the moisture content of the air flow flowing into the room, discharging dry air into the room, keeping the dryness of the gas discharged into the room, and thereby improving the dehumidification efficiency.

[0067] It is worth noting that each zone is provided with two vents 411 . According to the relative positions of the two vents 411 , the vent 411 located at the upper portion is referred to as the upper vent 411 , and the vent 411 located at the lower portion is referred to as the lower vent 411 .

[0068] like Figure 8-11As shown, in some optional embodiments, the desiccant assembly 400 includes: a housing 416, a humidity control rotary disk 417, and a first partition 418. The housing 416 defines a cavity 419, one end of which has an opening. The humidity control rotary disk 417 is rotatably disposed within the cavity 419, and a flow cavity is defined between the upper end surface of the humidity control rotary disk 417 and the inner wall of the cavity 419, allowing air to pass vertically through the humidity control rotary disk 417. The lower end surface of the humidity control rotary disk 417 is located at the opening. The first partition 418 is rotatably disposed within the flow cavity and divides the flow cavity into a first chamber 420 and a second chamber 421. In this way, the moisture in the airflow at normal temperature will be absorbed when it flows through the humidity control disc 417, and the moisture in the humidity control disc 417 will be released into the airflow when the heated airflow flows through the humidity control disc 417 that absorbs moisture. By utilizing this characteristic of the humidity control disc 417, the humidity control disc 417 is driven to rotate continuously below the first chamber 420 and the second chamber 421, and one of the airflow or the heated airflow passes through the humidity control disc 417 below the first chamber 420 into the first chamber 420, and then passes through the humidity control disc 417 below the first chamber 420 again to flow out, and the other passes through the humidity control disc 417 below the second chamber 421 into the second chamber 421, and then passes through the humidity control disc below the second chamber 421 again. 417 outflow, better absorbs moisture in the air flow, or better releases the absorbed moisture into the heated air flow, so that the indoor air can be continuously humidified or dehumidified better, and the first partition 418 can be driven to rotate and switch the air flow channel according to the outdoor environmental quality, so that the indoor air flow and the outdoor air flow can be exchanged or not exchanged during the humidification or dehumidification process, and then the indoor air flow and the outdoor air flow can be exchanged when there is a need for indoor ventilation, and the indoor air flow and the outdoor air flow can not be exchanged when the outdoor air quality is poor and there is no need for ventilation, so as to avoid outdoor polluted air from entering the room, selectively utilize outdoor air flow, reduce dependence on the outdoor environment, improve the stability of humidity regulation, and maintain the quality of indoor air.

[0069] Optionally, a heating unit 422 is provided in the first chamber 420 and / or the second chamber 421. In this way, the airflow flowing through the first chamber 420 and / or the second chamber 421 can be heated, so that the airflow flowing out of the first chamber 420 and / or the second chamber 421 can carry away moisture in the humidity control disc 417 located below the first chamber 420 and / or the second chamber 421, thereby achieving a humidification or dehumidification effect, and better continuously humidifying or dehumidifying the indoor air.

[0070] like Figure 12-16As shown, in some optional embodiments, the moisture absorption assembly 400 further includes a second partition 423. The second partition 423 is rotatably disposed at the lower end of the humidity control rotary disk 417 and connected to the first partition 418. The second partition 423 includes a first plate 424 and a second plate 425. The first plate 424 and the second plate 425 are arranged crosswise, and the first plate 424 is parallel to the first partition 418, and their centers are on the same vertical line. In this way, the second partition plate 423 is set at the lower end of the humidity control turntable 417, and a plurality of air inlet ends and air outlet ends can be defined on the lower end surface of the humidity control turntable 417 through the cross-arranged first plate 424 and the second plate 425. The outdoor and indoor air flows can enter the first chamber 420 or the second chamber 421 through the multiple air inlet ends, and then be discharged through the multiple air outlet ends, thereby better humidifying or dehumidifying the indoor environment. In the humidification or dehumidification process, the air flow channel can be switched according to the outdoor environmental quality, thereby improving the adaptability of the environment. Moreover, the first partition plate 418 is connected to the second partition plate 423, so that the first partition plate 418 can be connected to the second partition plate 423. A partition 418 rotates synchronously with the second partition 423. When the first partition 418 rotates to switch the air flow channel, the second partition 423 located at the lower end of the humidity control turntable 417 can rotate synchronously with the first partition 418. Since the first plate 424 of the second partition 423 is parallel to the first partition 418 and the centers are on the same vertical line, the first plate 424 of the second partition 423 is on the same vertical plane as the first partition 418 in the vertical direction. Therefore, the first partition 418 and the second partition 423 rotate synchronously, which can keep multiple air flow channels unobstructed and better humidify or dehumidify the indoor environment.

[0071] Optionally, the first partition 418 and the second partition 423 are connected by a connecting frame 426. The connecting frame 426 includes a first frame 427 and a second frame 428. The first frame 427 is a vertically arranged plate-like structure, and its upper and lower ends respectively connect one end of the first plate 424 and one end of the first partition 418; the second frame 428 is also a vertically arranged plate-like structure, and its upper and lower ends respectively connect the other end of the first plate 424 and the other end of the first partition 418. In this way, because the first plate 424 and the first partition 418 of the second partition 423 are on the same vertical plane and are connected at both ends by the vertically arranged connecting frame 426, the connecting frame 426 can better drive the rotation of the first partition 418 when the second partition 423 rotates, thereby improving the stability of the rotation of the first partition 418 and better switching the air flow channel connecting the indoor and outdoor spaces.

[0072] Optionally, the second partition 423 and the lower end surface of the humidity control turntable 417 define a first air inlet 429, a first air outlet 430, a second air inlet 431 and a second air outlet 432, and the first air inlet 429, the first air outlet 430, the second air inlet 431 and the second air outlet 432 are respectively connected to the first air inlet end 201, the first air outlet end 202, the second air inlet end 301 and the second air outlet end 302. When the first partition 418 is in the first position, the first air inlet 429 is connected to the first air outlet 430 through the first chamber 420, and the second air inlet 431 is connected to the second air outlet 432 through the second chamber 421; when the first partition 418 is in the second position, the first air inlet 429 is connected to the second air outlet 432 through the first chamber 420, and the second air inlet 431 is connected to the first air outlet 430 through the second chamber 421. In this way, the air flow passes through the first air inlet 429 and the second air inlet 431 through the humidity regulating disc 417 and flows into the first chamber 420 and the second chamber 421. Then the air flow flowing into the first chamber 420 and the second chamber 421 passes through the humidity regulating disc 417 again and is discharged through the first air outlet 430 and the second air outlet 432, thereby playing the role of humidification or dehumidification. The position of the first partition 418 can also be switched according to the quality of the outdoor environment, thereby realizing internal circulation humidification or dehumidification, or external circulation humidification or dehumidification. While continuously humidifying or dehumidifying the indoor environment, the air flow channel can be switched according to the quality of the outdoor environment, thereby improving environmental adaptability. For example, the first air inlet 429 is connected to the first air outlet 430 to the outdoors, and the second air inlet 431 is connected to the second air outlet 432 to the indoors. When the first partition 418 is in the first position, the first air inlet 429 is connected to the first air outlet 430 through the first chamber 420 to form an air flow channel for air intake from the outdoors and discharge to the outdoors, and the second air inlet 431 is connected to the second air outlet 432 through the second chamber 421 to form an air flow channel for air intake from the indoors and discharge to the indoors; when the first partition 418 is in the second position, the first air inlet 429 is connected to the second air outlet 432 through the first chamber 420 to form an air flow channel for air intake from the outdoors and discharge to the indoors, and the second air inlet 431 is connected to the first air outlet 430 through the second chamber 421 to form an air flow channel for air intake from the indoors and discharge to the outdoors.

[0073] Optionally, a first drive unit 433 is provided at the lower end of the second partition 423 to drive the rotation of the second partition 423. The first drive unit 433 includes a connecting disc 434 and a first motor 435. The connecting disc 434 is disposed at the lower end of the second partition 423 and is connected to the lower end surface of the second partition 423. A first annular rack 436 is disposed on its outer periphery. The output end of the first motor 435 engages with the first annular rack 436. Thus, when the first partition 418 needs to switch positions, the first motor 435 can drive the connecting disc 434 to rotate, thereby driving the second partition 423 to rotate. Since the second partition 423 is connected to the first partition 418 via the connecting bracket 426, the second partition 423 can drive the first partition 418 to rotate synchronously, thereby increasing the stability of the first partition 418 during rotation. This improves the switching of the airflow path between the indoor and outdoor spaces, allowing for continuous humidification or dehumidification of the indoor environment while also adjusting the airflow path according to the outdoor environment quality, thereby improving environmental adaptability.

[0074] Optionally, a second drive unit 437 is provided on the underside of the connecting disk 434, capable of driving the humidity control rotary disk 417 to rotate. The second drive unit 437 includes a transmission disc 438, an output shaft 439, and a second motor 440. The transmission disc 438 is rotatably disposed on the underside of the drive disc and is concentric with the drive disc. A second annular rack 441 is provided on the outer periphery of the transmission disc 438. The output shaft 439 passes through the center of the drive disc and the second partition 423, with one end fixedly connected to the circular portion of the transmission disc 438 and the other end fixedly connected to the center of the humidity control rotary disk 417. The output end of the second motor 440 is meshed with the second annular rack 441. In this way, the transmission disc 438 can be driven to rotate by the second motor 440, and then the output shaft 439 can be driven to rotate by the transmission disc 438, and the humidity control turntable 417 can be driven to rotate continuously by the output shaft 439, so that the humidity control turntable 417 is located below the first chamber 420 and the second chamber 421 and rotates continuously, and continuously absorbs and releases moisture during the rotation process, so as to better humidify or dehumidify the room. Since the transmission disc 438 is rotatably arranged on the lower side of the drive disc and is concentric with the drive disc, the output shaft 439 passes through the center of the second partition 423 and is connected to the humidity control turntable 417, so that the drive of the humidity control turntable 417 and the drive of the second partition 423 do not interfere with each other, thereby improving the stability of the humidity control turntable 417 during rotation.

[0075] In some embodiments, the dehumidification device is in the internal circulation dehumidification working condition, and the first partition 418 is in the first position. At this time, the outdoor is connected to the outdoor, and the indoor is connected to the indoor, that is, the first air inlet 429 is connected to the first air outlet 430 through the first chamber 420 to form an air flow channel for exhausting air from the outdoor to the outdoor, and the second air inlet 431 is connected to the second air outlet 432 through the second chamber 421 to form an air flow channel for exhausting air from the indoor to the indoor, and the outdoor air flow is discharged from the first air inlet end 200 of the first air duct. 01 is sent in, and after the air flow passes through the first heating mechanism 203 in the first air inlet end 201, the heated air flow passes through the first air inlet 429 on the lower end surface of the humidity control rotary disk 417 and enters the first chamber 420, and then blows out through the first air outlet 430 and flows into the second air flow cavity. The heated air flow regenerates the moisture in the humidity control rotary disk 417 and is finally discharged to the outside through the first air outlet end 202, completing a cycle of outdoor air flow. In this process, the humid air is discharged to the outside, reducing the indoor Humidity; The indoor air flow is sent into the second air inlet end 301 of the second air duct 300, and the air flow is sent into the second chamber 421 through the second air inlet 431 on the lower end surface of the humidity control rotary disk 417, and then blown out through the second air outlet 432 and flows into the first air flow cavity. The flow of the air flow in the humidity control rotary disk 417 causes the moisture in the air flow to be absorbed by the humidity control rotary disk 417. After the air flow flows out of the humidity control rotary disk 417, it enters the second air outlet end 302, and the air flow is dehumidified twice by the evaporator 500. The dry air is then discharged into the room by the second air outlet 302, thereby completing a cycle of the indoor air flow. In this process, the air flow dehumidified by the dehumidification component 400 is subjected to secondary dehumidification by the evaporator 500 provided in the second air outlet 302. Therefore, if the dehumidification by the dehumidification component 400 is not complete, the air flow is subjected to secondary dehumidification by the evaporator 500, thereby further reducing the water content of the air flow flowing into the room, and discharging the dry air into the room, thereby maintaining the dryness of the gas discharged into the room and improving the dehumidification efficiency.

[0076] Combine Figure 17 As shown, the device for dehumidification in the embodiment of the present disclosure further includes: an air purification module 800. The air purification module 800 is arranged in the first air outlet end 202 and / or the second air outlet end 302. In this way, by arranging the air purification module 800 in the first air outlet end 202 and / or the second air outlet end 302, the air flow can be adsorbed, decomposed or converted into various air pollutants by the air purification module 800 before being discharged into the room. The air purification module 800 can not only clean the toxic gases in the air, but also purify the air, remove bacteria, viruses, dust, mold spores, etc. in the air, effectively improve the cleanliness of the air, and provide users with a more comfortable living environment.

[0077] Optionally, the air purification module 800 is a negative ion air purifier. Thus, the negative ion air purifier can not only effectively remove particulate pollutants in the air and decompose harmful gases such as formaldehyde to provide clean air to the indoor environment, but also provide the indoor environment with negative air ions that have a highly effective effect on human health and well-being, thereby improving the quality of indoor air.
