Description

Technical Field

[0001] This invention relates to the field of air treatment technology, and in particular to an air treatment device. Background Technology

[0002] In related technologies, air handling units generally employ one of the following two schemes to achieve humidification. Scheme 1: A humidifying disc is installed in the lower air duct of the air handling unit. The disc is immersed in a water tank to absorb humidifying liquid (such as water or hypochlorous acid). The disc rotates, and the humidifying liquid is diffused into the air by a fan in the lower air duct. This scheme suffers from a relatively small humidification capacity due to the limited airflow in the lower air duct, typically only 200 cubic meters. Scheme 2: A vertically extending wet-film reel is installed in the air duct of the air handling unit. The rotating wet-film reel draws up the humidifying liquid in the bottom water tank. The rotation of the wet-film reel, combined with the rotation of a bottom fan, diffuses the humidifying liquid upwards into the air. This scheme provides a larger humidification capacity, but there is a problem that residual humidifying liquid is released for a period of time even after the unit is turned off.

[0003] In summary, traditional air handling units have a single humidification mode, cannot adjust the humidification volume, and cannot meet the different needs of users. Summary of the Invention

[0004] The main objective of this invention is to provide an air handling device that diversifies humidification modes and allows for adjustable humidification levels to meet different user needs.

[0005] To achieve the above objectives, the present invention provides an air handling apparatus comprising:

[0009] The humidification module can selectively release humidifying liquid toward the first air duct and / or the second air duct.

[0010] In one embodiment, the humidification module includes a water tank and a wet film assembly. The water tank is disposed in the first air duct, and the wet film assembly extends from the first air duct to the second air duct. The wet film assembly has a partial reciprocating rotation mode and a full rotation mode. In the partial reciprocating rotation mode, the portion of the wet film assembly located in the first air duct is wetted by the humidifying liquid in the water tank. In the full rotation mode, the entire wet film assembly is wetted by the humidifying liquid in the water tank.

[0011] In one embodiment, the first air duct is located below the second air duct, the first air inlet and the second air inlet are arranged vertically side by side on the same side of the housing, the wet film assembly extends vertically and is correspondingly arranged inside the first air inlet and the second air inlet, and the water tank is located below the wet film assembly.

[0012] In one embodiment, the wet film assembly includes a support frame, an active roll, a passive roll, a wet film, and a power unit. The support frame extends from the first air duct to the second air duct. The active roll and the passive roll are rotatably mounted at both ends of the support frame, respectively. The wet film is wound around the active roll and the passive roll. The power unit is driven by the active roll to drive the active roll to rotate.

[0013] In one embodiment, the air handling device further includes a drive mechanism drivenly connected to the wet film assembly, the wet film assembly having a first position immersed in humidifying liquid in the water tank and a second position separated from the humidifying liquid in the water tank, the drive mechanism being used to drive the wet film assembly to switch between the first position and the second position.

[0014] In one embodiment, the first air inlet and the first air outlet are respectively located on two opposite side walls of the housing; and / or, the second air inlet is located on the side wall of the housing, and the second air outlet is located on the top wall of the housing.

[0015] In one embodiment, the housing is further provided with a third air inlet communicating with the second air duct, and the air handling device further includes a first purification component disposed inside the third air inlet.

[0016] In one embodiment, the housing is further provided with a fourth air inlet communicating with the second air duct, and the air handling device further includes a second purification component disposed inside the fourth air inlet.

[0017] In one embodiment, the first purification component and / or the second purification component includes a plasma grid.

[0018] In one embodiment, the first fan assembly includes a first axial fan blade and a first drive motor drivenly connected to the first axial fan blade, and the second fan assembly includes a second axial fan blade and a second drive motor drivenly connected to the second axial fan blade, wherein the radial dimension of the second axial fan blade is larger than the radial dimension of the first axial fan blade.

[0019] In one embodiment, the air handling device further includes a valve assembly movably disposed between the second air inlet and the second air duct, for connecting or disconnecting the second air inlet and the second air duct.

[0022] The technical solution of this invention involves respectively arranging a first fan assembly and a second fan assembly within a first air duct and a second air duct. Simultaneously, the humidification module can selectively release humidifying liquid towards the first air duct and / or the second air duct. By controlling the simultaneous operation of the first fan assembly and the second fan assembly, or the operation of only one of them, and combining different operating states of the humidification module, multiple humidification modes can be achieved, including humidification of the first air duct alone, humidification of the second air duct alone, and humidification of both the first and second air ducts simultaneously. In the mode of humidifying the first air duct alone or the second air duct alone, a smaller humidification volume can be achieved; in the mode of humidifying the first and second air ducts simultaneously, a larger humidification volume can be achieved, thus enabling adjustable humidification.

[0041] This invention proposes an air handling device 100. The air handling device 100 can be any product, device, or component used for humidifying or disinfecting air. For example, the air handling device 100 can be an air humidifier, an air sterilizer, or an air conditioner. For ease of understanding, the following embodiments will use an air sterilizer as an example to illustrate the air handling device 100.

[0042] Please refer to Figures 1 to 4 In one embodiment of the present invention, the air handling device 100 includes a housing 10, a first fan assembly 20, a second fan assembly 30, and a humidification module. The housing 10 is provided with a first air inlet 11, a first air outlet 12, a second air inlet 13, and a second air outlet 14; a first air duct 15 connecting the first air inlet 11 and the first air outlet 12; and a second air duct 16 connecting the second air inlet 13 and the second air outlet 14. The first fan assembly 20 is disposed in the first air duct 15; the second fan assembly 30 is disposed in the second air duct 16; and the humidification module can selectively release humidifying liquid toward the first air duct 15 and / or the second air duct 16.

[0043] Specifically, the housing 10 forms the overall support structure of the air handling unit 100. The external contour of the housing 10 can be configured as a square or cylinder as needed. For example, in this embodiment, the housing 10 is generally a vertically extending square. The interior of the housing 10 can be constructed with box-like structures or partitions to form a first air duct 15 and a second air duct 16. An insertion port for the wet film assembly 50 to pass through is provided between the first air duct 15 and the second air duct 16. The first air duct 15 and the second air duct 16 can be arranged side by side in the horizontal direction or side by side in the vertical direction. The arrangement of the first air duct 15 and the second air duct 16 can be set according to the shape of the housing 10. For example, in this embodiment, the housing 10 extends vertically, and the first air duct 15 is located below the second air duct 16. The housing 10 is provided with a first air inlet 11, a first air outlet 12, a second air inlet 13, and a second air outlet 14. The shape of each air inlet and outlet can be set as a square, rectangle, circle, ellipse, or other irregular shape as needed. Air inlet grilles can be provided at the first air inlet 11 and the second air inlet 13, and air outlet grilles can be provided at the first air outlet 12 and the second air outlet 14. The air inlet grilles and air outlet grilles can prevent foreign objects from entering the housing 10, ensuring safety during use.

[0044] A first fan assembly 20 is disposed in a first air duct 15, used to introduce airflow from a first air inlet 11 into the first air duct 15 and send it out through a first air outlet 12. A second fan assembly 30 is disposed in a second air duct 16, used to introduce airflow from a second air inlet 13 into the second air duct 16 and send it out through a second air outlet 14. Both the first fan assembly 20 and the second fan assembly 30 include at least a fan wheel and a drive motor for driving the fan wheel to rotate. The fan wheel may include, but is not limited to, a centrifugal fan wheel, a cross-flow fan wheel, or an axial flow fan blade. The humidification module can selectively release humidifying liquid toward the first air duct 15 and / or the second air duct 16. The humidifying liquid may specifically be water, disinfectant, or other liquid.

[0045] In actual use, by controlling the first fan assembly 20 and the second fan assembly 30 to operate simultaneously or one of them, and in combination with the different working states of the humidification module, multiple humidification modes can be achieved, such as humidifying the first air duct 15 alone, humidifying the second air duct 16 alone, and humidifying the first air duct 15 and the second air duct 16 simultaneously. For example, when the first fan assembly 20 is turned on and the second fan assembly 30 is turned off, the humidification module releases humidifying liquid toward the first air duct 15, and the airflow enters the first air duct 15 through the first air inlet 11. During the airflow, the humidifying liquid can be sent out from the first air outlet 12 along with the airflow, thus achieving humidification of the first air duct 15 alone. When the first fan assembly 20 is turned off and the second fan assembly 30 is turned on, the humidification module releases humidifying liquid toward the second air duct 16, and the airflow enters the second air duct 16 through the second air inlet 13. During the airflow, the humidifying liquid can be sent out from the second air outlet 14 along with the airflow, thus achieving humidification of the second air duct 16 alone. When both the first fan assembly 20 and the second fan assembly 30 are turned on, the humidification module releases humidifying liquid toward the first air duct 15 and the second air duct 16, thus achieving humidification of the first air duct 15 and the second air duct 16 simultaneously.

[0046] The technical solution of this invention involves respectively arranging a first fan assembly 20 and a second fan assembly 30 within a first air duct 15 and a second air duct 16. Simultaneously, the humidification module can selectively release humidifying liquid towards the first air duct 15 and / or the second air duct 16. By controlling the simultaneous operation of the first fan assembly 20 and the second fan assembly 30, or the operation of one of them, and combining different operating states of the humidification module, multiple humidification modes can be achieved, including humidification of the first air duct 15 alone, humidification of the second air duct 16 alone, and humidification of both the first and second air ducts 15 simultaneously. In the mode of humidifying the first air duct 15 alone or the second air duct 16 alone, a smaller humidification volume can be achieved; in the mode of humidifying the first air duct 15 and the second air duct 16 simultaneously, a larger humidification volume can be achieved, thus enabling adjustable humidification. The air handling device of this invention has diverse humidification modes and adjustable humidification volume, which can well meet the different usage needs of users.

[0047] The humidification module can selectively humidify in various ways. For example, in one embodiment, the humidification module includes a water tank 40 and a wet film assembly 50. The wet film assembly 50 has a partial reciprocating rotation mode and a full rotation mode. By controlling the wet film assembly 50 to be in different rotation modes, the wet film assembly 50 can be partially or completely wetted by the humidifying liquid in the water tank 40, thereby selectively releasing the humidifying liquid toward different air ducts. In another embodiment, the humidification film is configured as a deformable structure, such as a telescopic structure. In the contracted state, the humidification module is located alone in the first air duct 15 or the second air duct 16, allowing it to release humidifying liquid separately toward either the first air duct 15 or the second air duct 16. In the extended state, the humidification module is simultaneously located in both the first air duct 15 and the second air duct 16, allowing it to release humidifying liquid simultaneously toward both the first air duct 15 and the second air duct 16.

[0048] In one embodiment, the humidification module includes a water tank 40 and a wet film assembly 50. The water tank 40 is disposed in the first air duct 15, and the wet film assembly 50 extends from the first air duct 15 to the second air duct 16. The wet film assembly 50 has a partial reciprocating rotation mode and a full rotation mode. In the partial reciprocating rotation mode, the portion of the wet film assembly 50 located in the first air duct 15 is wetted by the humidifying liquid in the water tank 40. In the full rotation mode, the entire wet film assembly 50 is wetted by the humidifying liquid in the water tank 40.

[0049] Specifically, the water tank 40 is used to store humidifying liquid. When the air handling unit 100 only needs to perform humidification, water can be added to the water tank 40, and the water diffuses into the air with the airflow to achieve air humidification. When the air handling unit 100 needs to perform both humidification and disinfection functions simultaneously, disinfectant can be added to the water tank 40, and the disinfectant diffuses into the air with the airflow to achieve both humidification and disinfection. Disinfectant includes, but is not limited to, hypochlorous acid, chlorine dioxide, or hydrogen peroxide. For example, in this embodiment, the air handling unit 100 specifically relates to an air sterilizer capable of humidification and disinfection. The humidifying liquid stored in the water tank 40 can specifically be hypochlorous acid. Hypochlorous acid solution has good sterilization and disinfection effects and is characterized by low cost, safety, and high efficiency.

[0050] The wet film assembly 50 is mainly used to absorb the humidifying liquid (such as hypochlorous acid solution) in the water tank 40. The wet film assembly 50, through program control, can achieve both partial reciprocating rotation and full-circle rotation modes. In different rotation modes, the wet film assembly 50 can be partially or entirely wetted by the humidifying liquid. Specifically, for example... Figure 10As shown, in the partial reciprocating rotation mode, the rotational angular velocity of the wet film assembly 50 adopts a sine wave form. In this mode, the wet film assembly 50 only rotates back and forth locally, so that only the part of the wet film assembly 50 located within the first air duct 15 is wetted by the humidifying liquid in the water tank 40. Figure 11 As shown, in the full rotation mode, the rotational angular velocity and rotational direction of the wet membrane remain unchanged, and the wet membrane assembly 50 rotates a full circle, so that the wet membrane assembly 50 can be completely wetted by the humidifying liquid in the water tank 40.

[0051] The air handling unit 100 described above can achieve at least the following humidification modes by controlling the operating states of the first fan assembly 20 and the second fan assembly 30, and by combining different rotation modes of the wet film assembly 50.

[0052] like Figure 6 As shown, in the first humidification mode, the first fan assembly 20 is turned on, the second fan assembly 30 is turned off, and the wet film assembly 50 is in a partial reciprocating rotation mode. In this mode, the part of the wet film assembly 50 within the first air duct 15 is wetted by the humidifying liquid in the water tank 40, while the part of the wet film assembly 50 within the second air duct 16 remains dry because it does not come into contact with the humidifying liquid. Under the action of the first fan assembly 20, airflow enters the first air duct 15 from the first air inlet 11. As the airflow passes through the wet film assembly 50, the humidifying liquid on the wet film assembly 50 can diffuse along with the airflow and be sent out from the first air outlet 12. In this mode, the air handling unit 100 only humidifies through the first air duct 15. The purpose of this mode is mainly to minimize the odor of the humidifying liquid (hypochlorous acid) or to reduce the amount of humidification.

[0053] like Figure 7 As shown, in the second humidification mode, the first fan assembly 20 is off, the second fan assembly 30 is on, and the wet film assembly 50 is in full rotation mode. In this mode, the entire wet film assembly 50 is soaked in the humidifying liquid in the water tank 40. Under the action of the second fan assembly 30, the airflow enters the second air duct 16 from the second air inlet 13. As the airflow passes through the wet film assembly 50, the humidifying liquid on the wet film assembly 50 can diffuse along with the airflow and be sent out from the second air outlet 14. In this mode, the air handling unit 100 humidifies only through the second air duct 16.

[0054] like Figure 8As shown, in the third humidification mode, both the first fan assembly 20 and the second fan assembly 30 are turned on, and the wet film assembly 50 is in full-circle rotation mode. In this mode, the entire wet film assembly 50 is soaked in the humidifying liquid in the water tank 40. Under the action of the first fan assembly 20 and the second fan assembly 30, part of the airflow enters the first air duct 15 from the first air inlet 11. As the airflow flows through the wet film assembly 50, the humidifying liquid on the wet film assembly 50 can diffuse along with the airflow and be sent out from the first air outlet 12. Another part of the airflow enters the second air duct 16 from the second air inlet 13. As the airflow flows through the wet film assembly 50, the humidifying liquid on the wet film assembly 50 can diffuse along with the airflow and be sent out from the second air outlet 14. In this mode, the air handling unit 100 can humidify simultaneously through the first air duct 15 and the second air duct 16, and the humidification capacity of the air handling unit 100 reaches its maximum.

[0055] The technical solution of this invention, by controlling the first fan assembly 20 and the second fan assembly 30 to operate simultaneously or one of them, and combining different rotation modes of the wet film assembly 50, can achieve multiple humidification modes, such as humidification of the first air duct 15 alone, humidification of the second air duct 16 alone, and humidification of the first air duct 15 and the second air duct 16 simultaneously. Furthermore, when the wet film assembly 50 is in a partial rotation mode, only the portion of the wet film assembly 50 located within the first air duct 15 is wetted by the humidifying liquid in the water tank 40, achieving a smaller humidification volume; when the wet film assembly 50 is in a full rotation mode, the entire wet film assembly 50 is wetted by the humidifying liquid in the water tank 40, achieving a larger humidification volume; thus, the humidification volume is adjustable. The air handling device 100 of this invention has multiple humidification modes and adjustable humidification volume, which can well meet the different usage needs of users.

[0056] The wet film assembly 50 extends from the first air duct 15 to the second air duct 16. The wet film assembly 50 can extend in a straight line, a zigzag shape, or a curved shape. In practical applications, it can be configured according to the arrangement of the first air duct 15 and the second air duct 16. For example, as... Figure 1 and Figure 6 As shown, in one embodiment, the first air duct 15 is located below the second air duct 16, the first air inlet 11 and the second air inlet 13 are arranged vertically side by side on the same side of the housing 10, the wet film assembly 50 extends vertically and is correspondingly arranged inside the first air inlet 11 and the second air inlet 13, and the water tank 40 is located below the wet film assembly 50.

[0057] Specifically, in this embodiment, the housing 10 is a vertically extending square body, and has a front sidewall, a rear sidewall, a left sidewall, a right sidewall, a top wall, and a bottom wall. A first air duct 15 and a second air duct 16 are formed inside the housing 10, arranged vertically. The first air duct 15 is located below the second air duct 16. A first air inlet 11 and a second air inlet 13 are both located on the rear sidewall of the housing 10, with the first air inlet 11 located below the second air inlet 13. A first air outlet 12 can be located on the front sidewall or the left or right sidewall of the housing 10, and a second air outlet 14 can be located on the top wall, front sidewall, or left or right sidewall of the housing 10. The wet film assembly 50 extends vertically and is disposed adjacent to the inner side of the first air inlet 11 and the second air inlet 13, resulting in a compact overall structure and small footprint. The water tank 40 is located below the wet membrane assembly 50. When the water tank 40 is filled with humidifying liquid, the humidifying liquid can contact the bottom of the wet membrane assembly 50. When the wet membrane assembly 50 is in a partial reciprocating rotation mode, the lower half of the wet membrane assembly 50 corresponding to the first air duct 15 can be wetted by the humidifying liquid.

[0058] In one embodiment, the first air inlet 11 and the first air outlet 12 are respectively located on two opposite side walls of the housing 10. Specifically, the first air inlet 11 is located on the rear side wall of the housing 10, the second air inlet 13 is located on the front side wall of the housing 10, the first air duct 15 extends along the front-rear direction of the housing 10, the wet film assembly 50 is located within the first air duct 15 and is adjacent to the inner side of the first air inlet 11, and the first fan assembly 20 is located near the first air outlet 12. The first fan assembly 20 can specifically be an axial flow fan, and under the action of the first fan assembly 20, rear air intake and front air exhaust can be achieved.

[0059] In one embodiment, the second air inlet 13 is located on the side wall of the housing 10, and the second air outlet 14 is located on the top wall of the housing 10. Specifically, the second air inlet 13 is located on the rear side wall of the housing 10, the second air outlet 14 is located on the top wall of the housing 10, the wet film assembly 50 is located within the second air duct 16 adjacent to the inner side of the second air inlet 13, and the second fan assembly 30 is located near the second air outlet 14. The second fan assembly 30 can specifically be an axial flow fan. Under the action of the second fan assembly 30, air can be introduced from the rear and discharged from the top, thereby achieving sedimentation humidification and sterilization, and improving the humidification and sterilization effect.

[0060] To enable the air handling unit 100 to perform its air purification function, please refer to... Figure 1 and Figure 5In one embodiment, the housing 10 is further provided with a third air inlet 17 communicating with the second air duct 16, and the air handling device 100 further includes a first purification component 60 disposed inside the third air inlet 17. Specifically, the side wall of the housing 10 is provided with a third air inlet 17, and the first purification component 60 is disposed adjacent to the inner side of the third air inlet 17. Under the action of the second fan assembly 30, the airflow enters the second air duct 16 from the third air inlet 17, and after being purified by the first purification component 60, it is blown out from the second air outlet 14, which can provide clean purified air for users.

[0061] To further enhance the air purification effect, the housing 10 is further provided with a fourth air inlet 18 communicating with the second air duct 16, and the air handling device 100 further includes a second purification component 70 disposed inside the fourth air inlet 18. The fourth air inlet 18 and the third air inlet 17 can be respectively disposed on two adjacent side walls or two opposite side walls of the housing 10, for example... Figure 5 As shown, in this embodiment, the third air inlet 17 is located on the right side wall of the housing 10, the fourth air inlet 18 is located on the left side wall of the housing 10, and the second purification component 70 is located adjacent to the inner side of the fourth air inlet 18. Under the action of the second fan component 30, the airflow enters the second air duct 16 from the fourth air inlet 18, and after being purified by the second purification component 70, it is blown out from the second air outlet 14. Since the third air inlet 17 and the fourth air inlet 18 can simultaneously intake air, the air intake volume is increased, and the purification is carried out simultaneously by the first purification component 60 and the second purification component 70, which can effectively improve the purification efficiency per unit time and improve the purification effect. In order to prevent foreign objects from entering the interior of the housing 10, air intake grilles can be provided at the third air inlet 17 and the fourth air inlet 18. The first purification component 60 and the second purification component 70 include, but are not limited to, the use of HEPA filters, activated carbon filters, TVOC (total volatile organic compounds) filters, formaldehyde removal filters, electrostatic dust collectors, ion generators, and ultraviolet sterilizers to achieve air purification.

[0062] In one embodiment, the first purification component 60 and / or the second purification component 70 include a plasma grid. Under the influence of an applied electric field, the plasma grid generates a large number of electrons to bombard pollutant molecules in the air, transforming large pollutant molecules into smaller, safer substances. Furthermore, to ensure a better ion purification effect, the airflow within the second air duct 16 is typically large, and the second air outlet 14 is located on the top wall of the housing 10, allowing the purified ionized air to be blown upwards, preventing the ionized air from directly blowing onto the user.

[0063] To further enhance the purification effect, the air handling unit 100 also includes a third purification component, which is located between the second fan assembly 30 and the second air outlet 14. Thus, the airflow can be purified again on the outlet side of the second air duct 16, achieving multiple purification effects.

[0064] The wet film assembly 50 can be rotated using a turntable or by winding a film. For example... Figure 5 As shown, in one embodiment, the wet film assembly 50 includes a support frame 51, an active roller 52, a driven roller 53, a wet film 54, and a power unit 55. The support frame 51 extends from the first air duct 15 to the second air duct 16. The active roller 52 and the driven roller 53 are rotatably mounted at both ends of the support frame 51, respectively. The wet film 54 is wound around the active roller 52 and the driven roller 53. The power unit 55 is drivenly connected to the active roller 52 to drive the active roller 52 to rotate.

[0065] Specifically, taking the first air duct 15 located below the second air duct 16 as an example, the support frame 51 extends vertically, the active roller 52 is located at the upper end of the support frame 51, and the driven roller 53 is located at the lower end of the support frame 51. The wet film 54 is wound around the active roller 52 and the driven roller 53. The outer periphery of the active roller 52 and the driven roller 53 may be provided with teeth or protrusions to increase the transmission friction between them and the wet film 54. The rotation output shaft of the power component 55 rotates, driving the active roller 52 to rotate, which in turn drives the wet film winding and the driven roller 53 to rotate. By controlling the power output mode of the power component 55, the wet film winding can be switched between a partial reciprocating rotation mode and a full rotation mode.

[0066] In addition, to achieve the humidification and disinfection function, the humidification solution generally uses a salt solution with bactericidal and disinfecting effects. When humidification and disinfection are not required, to prevent salt accumulation caused by the wet membrane module 50 being immersed in the humidification solution in the water tank 40 for a long time, such as... Figure 9 As shown, in one embodiment, the air handling device 100 further includes a drive mechanism 80 drivenly connected to the wet film assembly 50, the wet film assembly 50 having a first position wetted by the humidifying liquid in the water tank 40 and a second position separated from the humidifying liquid in the water tank 40, the drive mechanism 80 being used to drive the wet film assembly 50 to switch between the first position and the second position.

[0067] Specifically, when it is necessary to humidify the air through the air handling unit 100, the drive mechanism 80 drives the wet film assembly 50 to move to the first position (e.g., Figure 4As shown), in the first position, the end of the wet film assembly 50 closest to the water tank 40 is immersed in the humidifying liquid in the water tank 40. The humidifying liquid can move towards the wet film assembly 50 under the adsorption of the wet film assembly 50, so as to partially or completely wet the wet film assembly 50. When it is not necessary to humidify the air, the drive mechanism 80 drives the wet film assembly 50 to move to the second position (as shown). Figure 9 As shown), in the second position, the end of the wet membrane assembly 50 near the water tank 40 is separated from the humidifying liquid in the water tank 40, so that the wet membrane assembly 50 cannot be wetted by the humidifying liquid, the wet membrane assembly 50 remains dry, and the wet membrane assembly 50 will not accumulate salt due to long-term immersion in the humidifying liquid, thereby extending the service life of the wet membrane assembly 50.

[0068] There are several ways in which the drive mechanism 80 can switch the wet film assembly 50 between a first position and a second position. The drive mechanism 80 can drive the wet film assembly 50 to perform linear or curvilinear motion. In one embodiment, the wet film assembly 50 extends vertically, and the water tank 40 is located below the wet film assembly 50. The drive mechanism 80 includes a drive component mounted on the inner wall of the housing 10, a drive gear connected to the rotary output shaft of the drive component, and a driven rack connected to the wet film assembly 50. The drive gear meshes with the driven rack. The rotary output shaft of the drive component drives the drive gear to rotate, thereby causing the driven rack to drive the wet film assembly 50 to move up and down between the first and second positions. Of course, in other embodiments, the drive mechanism 80 can also drive the wet film assembly 50 to perform linear motion through a nut screw transmission structure, a synchronous belt pulley transmission structure, a linear push rod structure, etc.

[0069] In one embodiment, the first fan assembly 20 includes a first axial fan blade and a first drive motor drivenly connected to the first axial fan blade, and the second fan assembly 30 includes a second axial fan blade and a second drive motor drivenly connected to the second axial fan blade; the radial dimension of the second axial fan blade is larger than the radial dimension of the first axial fan blade.

[0070] Specifically, a first drive motor drives a first axial flow fan to rotate, generating negative pressure on the air inlet side of the first axial flow fan to guide the airflow at the first air inlet 11 to the first air outlet 12 via the first air duct 15; a second drive motor drives a second axial flow fan to rotate, generating negative pressure on the air inlet side of the second axial flow fan to guide the airflow at the second air inlet 13, the third air inlet 17, and the fourth air inlet 18 to the second air outlet 14 via the second air duct 16. Both the first fan assembly 20 and the second fan assembly 30 use axial flow fans for air delivery, resulting in a simple structure and low cost. Furthermore, the first air duct 15 uses small-sized axial flow fan blades, which can meet the usage requirements of the first humidification mode and achieve a smaller humidification capacity; the second air duct 16 uses large-sized axial flow fan blades, which can meet the usage requirements of the second and third humidification modes and achieve a larger humidification capacity. In the above embodiments, the second air duct 16 is further provided with a first purification component 60 and / or a second purification component 70, which adopts large-sized axial flow fan blades to accelerate the flow of purified air.

[0071] In addition, based on the above embodiments, the air handling device 100 further includes a valve assembly 90, which is movably disposed between the second air inlet 13 and the second air duct 16, for connecting or disconnecting the second air inlet 13 and the second air duct 16.

[0072] Specifically, such as Figure 6 As shown, in the first humidification mode, the valve assembly 90 isolates the second air inlet 13 from the second air duct 16. At this time, airflow can only enter the first air duct 15 from the first air inlet 11 and pass through the portion of the wet film assembly 50 located in the first air duct 15. Figure 7 and Figure 8 As shown, in the second and third humidification modes, the valve assembly 90 connects the second air inlet 13 to the second air duct 16, allowing airflow to enter the second air duct 16 from the second air inlet 13 and pass through the wet film assembly 50 located in the second air duct 16. Furthermore, when the second air duct 16 only needs to perform purification, the valve assembly 90 isolates the second air inlet 13 from the second air duct 16, allowing all airflow to enter the second air duct 16 for purification from the third air inlet 17 or the fourth air inlet 18, thus avoiding affecting the airflow passing through the first purification assembly 60 and the second purification assembly 70.

[0073] Please refer to Figure 9In one embodiment, the valve assembly 90 includes a bracket 91, a valve 92, and a drive unit. The bracket 91 is fixed to the housing 10, the valve 92 is movably connected to the bracket 91, and the drive unit is mounted on the bracket 91 and drivenly connected to the valve 92. Specifically, the valve 92 can be located on the air inlet side or the air outlet side of the wet film assembly 50. In this embodiment, since the wet film assembly 50 is located adjacent to the second air inlet 13, the valve 92 is located on the air outlet side of the wet film assembly 50 for ease of installation. The connection between the valve 92 and the bracket 91 can be either a rotational connection or a sliding connection. Correspondingly, the drive unit drives the valve 92 to rotate or slide relative to the bracket 91. For example, in this embodiment, the valve 92 and the bracket 91 are slidably connected through a slide rail and slide groove cooperation structure to ensure the movement stability of the valve 92.

[0074] There are various ways in which the drive unit can drive the valve 92 to move. In one embodiment, the drive unit includes a drive component 95, a gear 93, and a rack 94. The drive component 95 is mounted on the bracket 91, the gear 93 is connected to the rotary output shaft of the drive component 95, and the rack 94 is fixed to the valve 92. The gear 93 meshes with the rack 94. Specifically, the rack 94 extends vertically and drives the gear 93 to rotate via the rotary output shaft of the drive component 95, thereby driving the valve 92 to move vertically via the rack 94. The drive component 95 can be a stepper motor. Of course, in other embodiments, the drive unit can also drive the valve 92 to move via a nut screw drive structure, a synchronous belt pulley drive structure, a linear push rod, etc.

[0075] The following describes several operating modes of an air handling unit 100 according to a specific embodiment. The air handling unit 100 includes a housing 10, a first fan assembly 20, a second fan assembly 30, a water tank 40, a wet film assembly 50, a first purification assembly 60, a second purification assembly 70, a drive mechanism 80, and a valve assembly 90. The housing 10 is provided with a first air duct 15 and a second air duct 16. The first air duct 15 is located below the second air duct 16. The first air inlet 11 and the second air inlet 13 are both located on the rear side wall of the housing 10. The first air inlet 11 is located below the second air inlet 13. The first air outlet 12 is located on the front side wall of the housing 10. The second air outlet 14 is located on the top wall of the housing 10. The left and right side walls of the housing 10 are also provided with a third air inlet 17 and a fourth air inlet 18, respectively. The first air inlet 11 is connected to the first air outlet 12 via the first air duct 15. The second air inlet 13, the third air inlet 17 and the fourth air inlet 18 are all connected to the second air outlet 14 via the second air duct 16.

[0076] like Figure 6As shown, in the first humidification mode, the wet film assembly 50 is in the first position, the valve assembly 90 isolates the second air inlet 13 from the second air duct 16, the first fan assembly 20 is turned on, the second fan assembly 30 is turned off, and the wet film assembly 50 is in a partial reciprocating rotation mode. This mode achieves humidification of the first air duct 15 (i.e., humidification of the lower air duct). The purpose of this mode is mainly to minimize the odor of the humidifying liquid (hypochlorous acid) or to reduce the amount of humidification. Its main purpose is to determine the CADR value of the purification components (e.g., plasma grid) of the air handling unit 100.

[0077] like Figure 7 As shown, in the second humidification mode, the wet film assembly 50 is in the first position, the valve assembly 90 connects the second air inlet 13 to the second air duct 16, the first fan assembly 20 is closed, the second fan assembly 30 is turned on, and the wet film assembly 50 is in a full-circle rotation mode. In this mode, humidification of the second air duct 16 (i.e., upper air duct humidification) can be achieved.

[0078] like Figure 8 As shown, in the third humidification mode, the wet film assembly 50 is in the first position, the valve assembly 90 connects the second air inlet 13 to the second air duct 16, the first fan assembly 20 and the second fan assembly 30 are both turned on, and the wet film assembly 50 is in full rotation mode. In this mode, the first air duct 15 and the second air duct 16 can be humidified simultaneously (that is, the upper air duct and the lower air duct are humidified simultaneously), and the humidification capacity of the air handling unit 100 reaches its maximum.

[0079] like Figure 9 As shown, in non-humidification mode, the drive mechanism 80 drives the wet film assembly 50 to move to the second position. The end of the wet film assembly 50 near the water tank 40 is separated from the humidification liquid in the water tank 40, so that the wet film assembly 50 cannot be wetted by the humidification liquid and the wet film assembly 50 remains dry.

[0080] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
