[0043] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] The air handling device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The air handling device 100 can be used to treat air and has at least the function of purifying air; for example, the air handling device 100 can be a purifier or a sterilizer. In addition, the air handling device 100 may also have humidification, fresh air, and temperature regulation functions. The air handling device 100 can be placed on the ground for use. It can be moved or transported from one indoor space to another for use. For example, casters can be provided at the bottom of the air handling device 100 to facilitate its movement, allowing it to be easily moved to a designated location or indoor space for use. The air handling device 100 can also be mounted on a wall.

[0045] Reference Figure 1 and Figure 4 According to an embodiment of the present invention, the air handling device 100 may include: a housing 10, a first air supply handling component, and a second air supply handling component.

[0046] The housing 10 may have a first chamber 11 and a second chamber 21, which may be arranged in a certain direction. For example, the first chamber 11 and the second chamber 21 may be arranged vertically; the first chamber 11 and the second chamber 21 may also be arranged horizontally. Specifically, the first chamber 11 and the second chamber 21 may be arranged horizontally, or the first chamber 11 and the second chamber 21 may also be arranged front-back.

[0047] The first chamber 11 may have a first air inlet 12 and a first air outlet 13 formed on its wall. The first air inlet 12 is connected to the first chamber 11, and the first air outlet 13 is also connected to the first chamber 11. For example, the first air inlet 12 can connect the first chamber 11 to the interior, and the first air outlet 13 can connect the first chamber 11 to the interior. Indoor air can enter the first chamber 11 through the first air inlet 12 and finally be discharged out of the interior through the first air outlet 13. Alternatively, the first air inlet 12 can connect the first chamber 11 to the outside, and the first air outlet 13 can connect the first chamber 11 to the interior. Outdoor air can enter the first chamber 11 through the first air inlet 12 and finally be discharged out of the interior through the first air outlet 13.

[0048] A second air inlet 22 and a second air outlet 23 can be formed on the wall of the second chamber 21. The second air inlet 22 and the second air outlet 23 are connected to the second chamber 21. For example, the second air inlet 22 can connect the second chamber 21 to the interior, and the second air outlet 23 can connect the second chamber 21 to the interior. Indoor air can enter the second chamber 21 through the second air inlet 22 and finally be discharged out of the interior through the second air outlet 23. As another example, the second air inlet 22 can connect the second chamber 21 to the outside, and the second air outlet 23 can connect the second chamber 21 to the interior. Outdoor air can enter the second chamber 21 through the second air inlet 22 and finally be discharged out of the interior through the second air outlet 23.

[0049] The first air supply treatment component can be disposed within the first chamber 11, and may include a first fan unit 30 and a first air handling unit 40. When the first fan unit 30 is operating, it can drive air into the first chamber 11 from the first air inlet 12. After being treated by the first air handling unit 40, the air entering the first chamber 11 is discharged into the room from the first air outlet 13. The first air handling unit 40 may include a first purification module 41, which can purify the air entering the first chamber 11 and discharge the purified air into the room. When the first air inlet 12 is connected to the room, it can purify the indoor air and improve indoor air quality; when the first air inlet 12 is connected to the outside, it can purify the introduced fresh outdoor air and discharge the purified fresh outdoor air into the room, improving indoor air quality.

[0050] Optionally, the first purification module 41 can filter solid particles in the air. For example, the first purification module 41 may include a filter screen, such as a HEPA filter or an electrostatic precipitator filter. The first purification module 41 can also filter toxic and harmful gases in the air. For example, the first purification module 41 may include activated carbon, which can filter and remove toxic and harmful gases such as formaldehyde from the air. The first purification module 41 may also include a sterilization and disinfection component, which can remove harmful microorganisms such as bacteria and viruses from the air.

[0051] The second air supply treatment component can be located within the second chamber 21. This component may include a second fan unit 50 and a second air handling unit 60. When the second fan unit 50 operates, it drives air to enter the second chamber 21 through the second air inlet 22. The air entering the second chamber 21 is then processed by the second air handling unit 60 and discharged into the room through the second air outlet 23. The second air handling unit 60 may include a second purification module 61, which purifies the air entering the second chamber 21 and discharges the purified air into the room. When the second air inlet 22 is connected to the room, it can purify the indoor air, improving indoor air quality. When the second air inlet 22 is connected to the outside, it can purify the introduced fresh outdoor air and discharge the purified fresh outdoor air into the room, improving indoor air quality.

[0052] Optionally, the second purification module 61 can filter and fix airborne particles. For example, the second purification module 61 may include a filter screen, such as a HEPA filter or an electrostatic precipitator filter. The second purification module 61 can also filter toxic and harmful gases from the air. For example, the second purification module 61 may include activated carbon to filter and remove toxic and harmful gases such as formaldehyde from the air. The second purification module 61 may also include a sterilization and disinfection component, which can remove bacteria, viruses, and other harmful microorganisms from the air.

[0053] By setting up a first air supply treatment component and a second air supply treatment component, both components can operate simultaneously when the air handling unit 100 is working. This significantly increases the airflow and the amount of air purified per unit time, thereby improving purification efficiency and meeting the needs of large spaces. Furthermore, by providing a first chamber 11 and a second chamber 21 within the housing 10 to house the first and second air supply treatment components respectively, the mutual influence between the components can be reduced. For example, this avoids or reduces cross-flow and turbulent airflow, resulting in higher overall efficiency, lower noise, and easier modular installation of the first and second air supply treatment components.

[0054] Optionally, the first fan unit 30 and the second fan unit 50 can be controlled independently. When the first fan unit 30 and the second fan unit 50 are controlled independently, one of the first fan unit 30 and the second fan unit 50 can be controlled to work, or both of the first fan unit 30 and the second fan unit 50 can be controlled to work, depending on the size of the indoor space. For example, when the indoor space is small, only the first fan unit 30 or only the second fan unit 50 can be controlled to work, thereby meeting the purification needs while reducing energy consumption. When the indoor space is large, both the first fan unit 30 and the second fan unit 50 can be controlled to work, increasing the amount of air purified per unit time, thereby improving purification efficiency and meeting the needs of large spaces.

[0055] Optionally, the first fan unit 30 and the second fan unit 50 can also be controlled synchronously, that is, the first fan unit 30 and the second fan unit 50 work and stop at the same time. In this embodiment, since the first fan unit 30 and the second fan unit 50 can work simultaneously, the amount of air purified per unit time is increased, thereby improving the purification efficiency and meeting the needs of large spaces.

[0056] When both the first fan unit 30 and the second fan unit 50 are operating, the air volume can reach 800m³. 3 / h greatly increases the air volume, which can meet the needs of large spaces and effectively and quickly improve the indoor environment of large spaces in a short period of time.

[0057] For example, in some embodiments of the present invention, the first air inlet 12 is connected to the interior and the second air inlet 22 is connected to the interior, the first air outlet 13 is connected to the interior and the second air outlet 23 is connected to the interior. When only the first fan unit 30 is working, the first fan unit 30 drives indoor air from the first air inlet 12 into the first chamber 11. The indoor air entering the first chamber 11 is processed by the first air handling unit 40 and then discharged into the interior from the first air outlet 13. When only the second fan unit 50 is working, the second fan unit 50 drives indoor air from the second air inlet 22 into the second chamber 21. The indoor air entering the second chamber 21 is processed by the second air handling unit 60 and then discharged into the interior from the second air outlet 23. When the first fan unit 30 and the second fan unit 50 are operating, the first fan unit 30 drives indoor air into the first chamber 11 through the first air inlet 12, while the second fan unit 50 drives indoor air into the second chamber 21 through the second air inlet 22. The indoor air entering the first chamber 11 is processed by the first air handling unit 40 and then discharged into the room through the first air outlet 13. Simultaneously, the indoor air entering the second chamber 21 is processed by the second air handling unit 60 and then discharged into the room through the second air outlet 23. In this embodiment, indoor air can be purified, improving indoor air quality.

[0058] For example, in some other embodiments of the present invention, the first air inlet 12 is connected to the outside and the second air inlet 22 is connected to the outside, the first air outlet 13 is connected to the inside and the second air outlet 23 is connected to the inside. When only the first fan unit 30 is working, the first fan unit 30 drives outdoor air into the first chamber 11 from the first air inlet 12. The outdoor air entering the first chamber 11 is processed by the first air handling unit 40 and then discharged into the room from the first air outlet 13. When only the second fan unit 50 is working, the second fan unit 50 drives outdoor air into the second chamber 21 from the second air inlet 22. The outdoor air entering the second chamber 21 is processed by the second air handling unit 60 and then discharged into the room from the second air outlet 23. When the first fan unit 30 and the second fan unit 50 are operating, the first fan unit 30 drives outdoor air into the first chamber 11 through the first air inlet 12, while the second fan unit 50 drives outdoor air into the second chamber 21 through the second air inlet 22. The outdoor air entering the first chamber 11 is processed by the first air handling unit 40 and then discharged into the room through the first air outlet 13. Simultaneously, the outdoor air entering the second chamber 21 is processed by the second air handling unit 60 and then discharged into the room through the second air outlet 23. In this embodiment, the introduced outdoor air can be purified, improving indoor air quality.

[0059] For example, in some other embodiments of the present invention, the first air inlet 12 is connected to the interior and the second air inlet 22 is connected to the exterior, the first air outlet 13 is connected to the interior and the second air outlet 23 is connected to the interior. When only the first fan unit 30 is working, the first fan unit 30 drives indoor air into the first chamber 11 from the first air inlet 12. The indoor air entering the first chamber 11 is processed by the first air handling unit 40 and then discharged into the interior from the first air outlet 13. When only the second fan unit 50 is working, the second fan unit 50 drives outdoor air into the second chamber 21 from the second air inlet 22. The outdoor air entering the second chamber 21 is processed by the second air handling unit 60 and then discharged into the interior from the second air outlet 23. When the first fan unit 30 and the second fan unit 50 are operating, the first fan unit 30 drives indoor air into the first chamber 11 through the first air inlet 12, while the second fan unit 50 drives outdoor air into the second chamber 21 through the second air inlet 22. The indoor air entering the first chamber 11 is processed by the first air handling unit 40 and then discharged into the room through the first air outlet 13. Simultaneously, the outdoor air entering the second chamber 21 is processed by the second air handling unit 60 and then discharged into the room through the second air outlet 23. In this embodiment, both indoor and outdoor air can be purified, improving indoor air quality.

[0060] For example, in some other embodiments of the present invention, the first air inlet 12 is connected to the outside and the second air inlet 22 is connected to the inside, the first air outlet 13 is connected to the inside and the second air outlet 23 is connected to the inside. When only the first fan unit 30 is working, the first fan unit 30 drives outdoor air into the first chamber 11 from the first air inlet 12. The outdoor air entering the first chamber 11 is processed by the first air handling unit 40 and then discharged into the room from the first air outlet 13. When only the second fan unit 50 is working, the second fan unit 50 drives indoor air into the second chamber 21 from the second air inlet 22. The indoor air entering the second chamber 21 is processed by the second air handling unit 60 and then discharged into the room from the second air outlet 23. When the first fan unit 30 and the second fan unit 50 are operating, the first fan unit 30 drives outdoor air into the first chamber 11 through the first air inlet 12, while the second fan unit 50 drives indoor air into the second chamber 21 through the second air inlet 22. The outdoor air entering the first chamber 11 is processed by the first air handling unit 40 and then discharged into the room through the first air outlet 13. Simultaneously, the indoor air entering the second chamber 21 is processed by the second air handling unit 60 and then discharged into the room through the second air outlet 23. In this embodiment, both indoor and outdoor air can be purified, improving indoor air quality.

[0061] Optionally, the air outlet 13 can have a different air outlet direction than the second air outlet 23. This allows the air handling unit 100 to have more air outlet directions and a wider air outlet range. When both the first fan unit 30 and the second fan unit 50 are working, it is beneficial to drive the air flow in different directions of the air handling unit 100, so that the indoor air quality can be effectively improved and the air handling efficiency can be further improved.

[0062] For example, the first chamber 11 and the second chamber 21 can be arranged vertically, and the first air outlet 13 and the second air outlet 23 can be arranged vertically. In this way, when both the first fan unit 30 and the second fan unit 50 of the air handling device 100 are working, the air handling device 100 can blow the purified air into the room through the first air outlet 13 and into the room through the second air outlet 23. This can quickly and effectively improve the air quality in both the upper and lower layers of the indoor space.

[0063] For example, the first chamber 11 and the second chamber 21 can be arranged in the left-right direction, and the first air outlet 13 and the second air outlet 23 can be arranged in the left-right direction. In this way, when both the first fan unit 30 and the second fan unit 50 of the air handling device 100 are working, the air handling device 100 can blow the purified air into the room through the first air outlet 13 and into the room through the second air outlet 23. This can make the air quality in the left and right parts of the room along the horizontal direction quickly and effectively improved.

[0064] According to an embodiment of the present invention, the air handling device 100, by providing two chambers inside the housing 10 and respectively providing air supply treatment components with purification functions in the two chambers, can significantly increase the air volume and improve the air purification efficiency, thus meeting the needs of large spaces.

[0065] According to some embodiments of the present invention, the first fan unit 30 and the second fan unit 50 are both controlled independently. Therefore, one of the first fan unit 30 and the second fan unit 50 can be controlled to operate, or both can be controlled to operate, depending on the size of the indoor space. For example, in a small indoor space, only the first fan unit 30 or only the second fan unit 50 can be controlled to operate, thereby meeting purification requirements while reducing energy consumption; in a large indoor space, both the first fan unit 30 and the second fan unit 50 can be controlled to operate, increasing the amount of air purified per unit time, thereby improving purification efficiency and meeting the needs of large spaces.

[0066] Furthermore, since the first fan unit 30 and the second fan unit 50 are both independently controlled, the air handling unit 100 can be controlled to have different air handling modes. This allows the air handling unit 100 to activate the corresponding air handling mode according to actual needs, which can not only meet the needs of large spaces, but also meet the needs of more working modes.

[0067] For example, when both the first air inlet 12 and the second air inlet 22 are connected to the room, the small air volume mode and the large air volume mode can be switched according to the size of the room. When one of the first fan unit 30 and the second fan unit 50 is working, the small air volume mode is implemented; when both the first fan unit 30 and the second fan unit 50 are working, the large air volume mode is implemented.

[0068] For example, when both the first air inlet 12 and the second air inlet 22 are connected to the room, the second air handling unit 60 may also include a humidification module 62. This allows for switching between low-volume and high-volume modes based on the size of the room. Furthermore, the operation of the second fan unit 50 can control whether or not the indoor air is humidified. When the second fan unit 50 is operating, it can both purify and humidify the indoor air.

[0069] For example, when both the first air inlet 12 and the second air inlet 22 are connected to the outside, the system can switch between low-volume and high-volume modes depending on the size of the indoor space. When one of the first fan unit 30 and the second fan unit 50 is operating, a low-volume mode is implemented, allowing for the introduction of less outdoor fresh air. When both fan units 30 and 50 are operating, a high-volume mode is implemented, allowing for the introduction of more outdoor fresh air. Optionally, the operation of the first fan unit 30 and the second fan unit 50 can be controlled based on the indoor carbon dioxide concentration. For instance, when the indoor carbon dioxide concentration is high, both fan units 30 and 50 can be operated to introduce more fresh outdoor air, quickly reducing the indoor carbon dioxide concentration and rapidly improving indoor air quality. When the indoor carbon dioxide concentration is low, only one of the first fan unit 30 or the second fan unit 50 can be activated, effectively reducing indoor carbon dioxide levels and lowering overall energy consumption.

[0070] For example, when both the first air inlet 12 and the second air inlet 22 are connected to the outside, the second air handling unit 60 may also include a humidification module 62. This allows for switching between low-volume and high-volume modes based on the size of the indoor space. Furthermore, the operation of the second fan unit 50 can control whether or not outdoor air is humidified. When the second fan unit 50 is operating, it can both purify and humidify the outdoor air.

[0071] For example, when one of the first air inlet 12 and the second air inlet 22 is connected to the indoor environment and the other is connected to the outdoor environment, it is possible to switch between low-volume and high-volume modes according to the size of the indoor space. Furthermore, different air circulation modes can be achieved by controlling the first fan unit 30 and the second fan unit 50. For instance, when the first air inlet 12 is connected to the indoor environment and the second air inlet 22 is connected to the outdoor environment, indoor air can be purified and circulated when only the first fan unit 30 is operating; when only the second fan unit 50 is operating, outdoor air can be purified and circulated; when both the first fan unit 30 and the second fan unit 50 are operating, the first air supply processing component circulates indoor air, and the second air supply processing component circulates both indoor and outdoor air.

[0072] According to some embodiments of the present invention, with reference to Figure 1 and Figure 4 The first chamber 11 and the second chamber 21 can be isolated from each other, meaning they are not interconnected. This reduces the mutual influence between the airflow in the first chamber 11 and the airflow in the second chamber 21, thereby improving the overall efficiency of the machine, reducing airflow turbulence, and lowering noise. For example, a partition 103 can be installed inside the housing 10 to divide the space inside the housing 10 into the aforementioned isolated first chamber 11 and second chamber 21. The partition 103 can be a hollow structure, which can further reduce the mutual influence between the first chamber 11 and the second chamber 21.

[0073] According to some embodiments of the present invention, the housing 10 includes a first sub-housing and a second sub-housing, which can be detachably connected. For example, the first and second sub-housings can be connected by snap-fit, or by fasteners such as screws, or by a combination of snap-fit ​​and fasteners. The first sub-housing has a first chamber 11, and the second sub-housing has a second chamber 21. By configuring the housing 10 to include detachably connected first and second sub-housings, maintenance of the components within the housing 10 can be conveniently achieved.

[0074] Furthermore, by configuring the housing 10 to include a detachably connected first sub-housing and a second sub-housing, it is advantageous to detach the first air handling assembly and the second air handling assembly in the air handling unit 100 for individual use. For example, the first fan unit 30 and the second fan unit 50 are independently controlled, the first chamber 11 and the second chamber 21 are isolated from each other, and the housing 10 is configured to include a detachably connected first sub-housing and a second sub-housing, the first sub-housing having a first chamber 11 and the second sub-housing having a second chamber 21. In this way, the first air supply treatment component and the first sub-casing can constitute a first sub-air handling device, and the second air supply treatment component and the second sub-casing can constitute a second sub-air handling device. This allows the air handling device 100 to be disassembled into two parts, the first and second sub-air handling devices, for independent use. For example, after further disassembling the air handling device 100 into these two parts, one of the first and second sub-air handling devices can operate as needed, or the first and second sub-air handling devices can be placed in different indoor spaces, or they can be located at different positions within the same indoor space. Of course, the first and second sub-air handling devices can also be assembled into a single, integrated air handling device 100 for operation.

[0075] According to some embodiments of the present invention, with reference to Figure 1 , Figure 4 , Figure 6 and Figure 7 The first fan unit 30 may include a first impeller 32, which may be an axial flow impeller. The second fan unit 50 may include a second impeller 52, which may also be an axial flow impeller. By setting at least two axial flow impellers, the high flow rate of axial flow impellers can be utilized to significantly increase the air volume and better meet the needs of large spaces.

[0076] According to some optional embodiments of the present invention, refer to Figure 1 , Figure 4 , Figure 6 and Figure 7The first chamber 11 can be located above the second chamber 21. The axis of the second impeller 52 can extend in the front-to-back direction. Since the airflow of the axial impeller flows parallel to its axis, the second air inlet 22 and the second air outlet 23 can be formed on the circumferential sidewall of the second chamber 21. The air can flow roughly horizontally, thus avoiding air pollution caused by dust being sucked up from the ground due to bottom air intake. Furthermore, the axis of the first impeller 32 extends vertically. Since the first impeller 32 is located in the upper first chamber 11, the first air inlet 12 can be formed on the circumferential sidewall of the first chamber 11 and the first air outlet 13 can be formed on the top wall of the first chamber 11, achieving horizontal air intake and upward air exhaust. This not only avoids air pollution caused by bottom-mounted air intake easily sucking up dust from the ground, but also allows for air outlets in different directions, including horizontal and upward air outlets, expanding the air supply angle and range. Furthermore, the air outlet direction setting can prevent the airflow from easily sucking up dust from the ground and causing air pollution.

[0077] In this design, since the axis of the lower second impeller 52 extends in the front-to-back direction, and the second air inlet 22 and the second air outlet 23 corresponding to the second impeller 52 are both formed on the circumferential sidewall of the second chamber 21, during the operation of the first fan unit 30, the second air inlet 22 draws in air in the horizontal direction. The negative pressure zone near the second air inlet 22 is located on one side of the horizontal direction of the second air inlet 22 rather than on the lower side. This avoids the negative pressure zone forming below the air inlet, which would draw in air from below and cause dust to be sucked up from the ground. At the same time, the area with the highest airflow velocity near the second impeller 52 is also in the direction adjacent to the central axis of the second impeller 52, so that the area with the highest airflow velocity near the second impeller 52 is at a greater distance from the ground, thus better preventing dust from being sucked up from the ground.

[0078] For example, in Figure 1 and Figure 4In a specific example, the air handling unit 100 includes a housing 10, a first air supply processing component, and a second air supply processing component. The housing 10 has a first chamber 11 and a second chamber 21 that are separated from each other. The first chamber 11 is located above the second chamber 21. The first air supply processing component is located within the first chamber 11, and the second air supply processing component is located within the second chamber 21. A second air inlet 22 is formed on the circumferential sidewall of the second chamber 21, and a second air outlet 23 is formed on the circumferential sidewall of the second chamber 21. For example, the second air inlet 22 is formed on the left and right sidewalls of the second chamber 21, thereby increasing the air intake area of ​​the second air inlet 22 and thus increasing the air intake volume. The second air outlet 23 is formed on the front sidewall of the second chamber 21, thereby achieving forward airflow from the second air outlet 23. The first air inlet 12 is formed on the circumferential sidewall of the first chamber 11, and the first air outlet 13 is formed on the top of the first chamber 11. For example, the first air inlet 12 can be formed on the left sidewall, the right sidewall, and the rear sidewall of the first chamber 11, thereby increasing the air intake area of ​​the first air inlet 12 and thus increasing the air intake volume of the first air inlet 12. By setting both the air intake area of ​​the first air inlet 12 and the air intake area of ​​the second air inlet 22 to be relatively large, the air intake volume of the whole unit can be significantly improved, thereby increasing the air handling capacity of the whole unit per unit time.

[0079] The first air supply treatment assembly includes a first fan unit 30 and a first air handling unit 40. The first fan unit 30 includes a first air duct component 31, a first impeller 32, and a first motor 33. The first air duct component 31 defines a first air duct 311. The first impeller 32 is disposed in the first air duct 311, and the axis of the first impeller 32 extends vertically. The first motor 33 is connected to one axial end of the first impeller 32 to drive the first impeller 32 to rotate. The first motor 33 can be connected to the upper end of the first impeller 32. The first purification module 41 can be disposed adjacent to the first air inlet 12 and / or the first air outlet 13. Alternatively, there can be two first purification modules 41, one of which is disposed adjacent to the first air inlet 12, and the other of which is disposed adjacent to the first air outlet 13.

[0080] Specifically, the first impeller 32 is located in the upper half of the first chamber 11, adjacent to the first air outlet 13. One of the two first purification modules 41 is located on the air outlet side of the first impeller 32 and above the first motor 33. The first air inlet 12 is formed on the circumferential sidewall of the lower part of the first chamber 11, and the other of the two first purification modules 41 is adjacent to the first air inlet 12 and located in the lower half of the first chamber 11. When the first impeller 32 rotates, the driving air enters the first chamber 11 from the first air inlet 12 located in the lower part of the first chamber 11, and after being purified by the first purification module 41 adjacent to the first air inlet 12, it flows upward. During the upward flow of the air in the first chamber 11, it is accelerated by the first impeller 32 and then purified again by the first purification module 41 adjacent to the first air outlet 13, and finally blown out into the room from the first air outlet 13 on the upper side.

[0081] The second air supply treatment assembly includes a second fan unit 50 and a second air handling unit 60. The second fan unit 50 includes a second air duct component 51, a second impeller 52, and a second motor 53. The second air duct component 51 defines a second air duct 511. The second impeller 52 is disposed in the second air duct 511, and the axis of the second impeller 52 extends in the front-rear direction. The second motor 53 is connected to one axial end of the second impeller 52 to drive the second impeller 52 to rotate. The second motor 53 can be connected to the front end of the second impeller 52. The second impeller 52 can be located in the front half of the second chamber 21, adjacent to the second air outlet 23. The second purification module 61 is disposed at the other axial end of the second impeller 52 away from the second motor 53. The second purification module 61 is located on the rear side of the second impeller 52, and the second air inlet 22 is located on the rear side of the second purification module 61. When the second impeller 52 rotates, the driving air enters the second chamber 21 from the second air inlet 22 at the rear. The air in the second chamber 21 flows forward. During the forward flow of the air in the second chamber 21, it is purified by the second purification module 61, and then accelerated by the second impeller 52 before being blown out into the room from the second air outlet 23 on the front side.

[0082] According to some optional embodiments of the present invention, refer to Figure 1 , Figures 3-5 as well as Figure 7The first fan unit 30 includes a first impeller 32, which is an axial flow impeller. The first fan unit 30 may include a first air duct component 31, which defines a first air duct 311. The first air duct 311 is used to accommodate the first impeller 32, that is, the first impeller 32 is disposed within the first air duct 311. The first air duct 311 may include a first air duct section 3111 and a second air duct section 3112. In the airflow direction within the first air duct 311, the second air duct section 3112 may be connected to the upstream side of the first air duct section 3111 (for example, the second air duct section 3112 may be connected to the lower side of the first air duct section 3111). The first air duct section 3111 may be generally cylindrical, and the cross-sectional area of ​​the first air duct section 3111 may remain approximately unchanged along the axial direction of the first air duct 311 (for example, along the vertical direction). The cross-sectional area of ​​the first air duct section 3111 refers to the area of ​​the cross section obtained by cutting the first air duct section 3111 with a plane perpendicular to the axis of the first wind turbine 32.

[0083] In the direction from the air inlet side to the air outlet side of the first impeller 32 (e.g., in the direction from bottom to top), at least a portion of the second air duct section 3112 is tapered. For example, the entire second air duct section 3112 may be tapered, or only a portion of the second air duct section 3112 may be tapered. In the airflow direction within the first air duct 311, the cross-sectional area of ​​the second air duct section 3112 decreases along the axial direction of the first air duct 311. Therefore, the airflow entering the first chamber 11 can be guided into the first air duct 311 by the second air duct section 3112, reducing the resistance to airflow entering the first air duct 311 and simultaneously reducing the noise generated by the airflow passing through the first air duct 311, thus helping to increase airflow volume. The cross-sectional area of ​​the second air duct section 3112 refers to the area of ​​the cross-section obtained by cutting the second air duct section 3112 with a plane perpendicular to the axis of the first impeller 32.

[0084] In some embodiments of the present invention, reference is made to... Figure 1 , Figures 3-5 as well as Figure 7The inner wall of the first air duct 311 may include a first air duct wall 312 and a second air duct wall 313, which may be arranged circumferentially along the first air duct 311. The axial section of the first air duct wall 312 (the axial section of the first air duct wall 312 refers to the section obtained by cutting the first air duct wall 312 with a plane passing through the axis of the first impeller 32) may include a first air duct wall segment 3121 and a second air duct wall segment 3122, wherein the first air duct wall segment 3121 is located in the first air duct segment 3111, and the second air duct wall segment 3122 is located in the second air duct segment 3112. The first air duct wall segment 3121 may extend axially parallel to the first impeller 32. The first air duct wall segment 3121 extends in a generally straight line, for example, the first air duct wall segment 3121 extends in a straight line in the vertical direction, which can reduce the noise generated during the airflow through the first air duct segment 3111 and make the airflow smoother. In the direction from the air inlet side of the first impeller 32 to the air outlet side of the first impeller 32 (e.g., in the direction from bottom to top), the second duct wall section 3122 extends obliquely towards the center of the adjacent second duct section 3112. For example, the second duct wall section 3122 can extend in a straight line, an arc, or a spline curve. During the flow of air from the second duct section 3112 into the first duct section 3111, the second duct wall section 3122 can act as a guide, better directing the airflow into the first duct 311, making the airflow smoother, reducing noise, and helping to increase the air volume.

[0085] The axial section of the second air duct wall 313 (the axial section of the second air duct wall 313 refers to the section obtained by cutting the second air duct wall 313 with a plane passing through the axis of the first impeller 32) may include a third air duct wall segment 3131 and a fourth air duct wall segment 3132. The third air duct wall segment 3131 is located in the first air duct segment 3111, and the fourth air duct wall segment 3132 is located in the second air duct segment 3112. The third air duct wall segment 3131 extends along an axial direction parallel to the first impeller 32 and extends in a straight line. The fourth air duct wall segment 3132 extends along an axial direction parallel to the first impeller 32 and extends in a straight line. The third air duct wall segment 3131 and the fourth air duct wall segment 3132 can be arranged approximately collinearly. This optimizes the air duct structure, allowing for better airflow into the first air duct 311 while further reducing airflow resistance and helping to increase the output air volume.

[0086] In some embodiments of the present invention, reference is made to... Figure 7The first air duct section 3111 has a cross-sectional diameter of D1, the second air duct section 3112 has a maximum cross-sectional diameter of D2, and the first chamber 11 has a rectangular cross-section. The length and width of the first chamber 11's cross-section are L1 and L2, respectively, where D1 < D2 < Lmin, and Lmin is the minimum of L1 and L2. When the cross-section of the first chamber 11 obtained by cutting a plane perpendicular to the axial direction of the first impeller 32 is rectangular, the length of the first chamber 11 is L1 and the width of the first chamber 11 is L2. In this case, the value of Lmin can be the smaller of L2 and L1. For example, if the width L2 is not greater than the length L1, then the value of Lmin can be L2. By setting the maximum diameter of the second air duct section 3112, which has a tapering shape, within the above range, the space of the first chamber 11 can be fully utilized. Increasing the maximum diameter of the second air duct section 3112 helps reduce airflow resistance and allows for a larger diameter of the corresponding first impeller 32, which increases airflow and makes the overall structure more compact.

[0087] It should be explained that the cross-sectional diameter of the first air duct section 3111 refers to the diameter of the cross-section obtained by cutting the first air duct section 3111 with a plane perpendicular to the axial direction of the first impeller 32. The cross-sectional diameter of the second air duct section 3112 refers to the diameter of the cross-section obtained by cutting the second air duct section 3112 with a plane perpendicular to the axial direction of the first impeller 32. The cross-section of the first chamber 11 refers to the cross-section obtained by cutting the first chamber 11 with a plane perpendicular to the axial direction of the first impeller 32.

[0088] In some embodiments of the present invention, reference is made to... Figure 7 The cross-sectional diameter of the first air duct section 3111 is D1, and the diameter of the first impeller 32 is D0, where D0+10mm≤D1≤D0+30mm. By limiting the relationship between the cross-sectional diameter D1 of the first air duct section 3111 and the diameter D0 of the first impeller 32, the gap between the first impeller 32 and the inner peripheral wall of the first air duct section 3111 is effectively limited. If the gap between the first impeller 32 and the inner peripheral wall of the first air duct section 3111 is too small, the first impeller 32 may interfere with the inner peripheral wall of the first air duct section 3111 during rotation, preventing the first impeller 32 from operating normally and smoothly. If the gap between the first impeller 32 and the inner peripheral wall of the first air duct section 3111 is too large, more airflow will flow along the gap between the first impeller 32 and the inner peripheral wall of the first air duct section 3111, reducing the efficiency of the first impeller 32. By setting the relationship between the cross-sectional diameter D1 of the first air duct section 3111 and the diameter D0 of the first impeller 32 within the above range, it is possible to ensure the normal rotation of the first impeller 32 and make the first impeller 32 work more efficiently, thereby helping to improve air volume and wind speed.

[0089] In some embodiments of the present invention, reference is made to... Figure 1 , Figure 4 and Figure 6 The second fan unit 50 includes a second impeller 52, which is an axial flow impeller. The second fan unit 50 also includes a second air duct component 51, which defines a second air duct 511 for accommodating the second impeller 52. The shape of the second air duct 511 may be similar to that of the first air duct 311.

[0090] In some specific embodiments of the present invention, reference is made to... Figure 1 , Figure 4 and Figure 6 The second air duct 511 may include a third air duct section 5111 and a fourth air duct section 5112. In the airflow direction within the second air duct 511, the fourth air duct section 5112 may be connected upstream of the third air duct section 5111 (e.g., the fourth air duct section 5112 may be connected downstream of the third air duct section 5111). The third air duct section 5111 may be generally cylindrical, and its cross-sectional area may remain approximately constant along the axial direction of the second air duct 511 (e.g., along the front-to-back direction). In the direction from the air inlet side to the air outlet side of the second impeller 52 (e.g., in the rear-to-front direction), at least a portion of the second air duct section 5112 is tapered, and in the airflow direction within the second air duct 511 (e.g., in the rear-to-front direction), the cross-sectional area of ​​the fourth air duct section 5112 decreases. Therefore, the airflow entering the second chamber 21 can be guided into the second air duct 511 under the guidance of the fourth air duct section 5112, which can reduce the resistance of the airflow entering the second air duct 511 and reduce the noise generated by the airflow passing through the second air duct 511, thus helping to increase the air volume.

[0091] The cross-sectional area of ​​the third air duct section 5111 refers to the area of ​​the cross-section obtained by cutting the third air duct section 5111 with a plane perpendicular to the axis of the second wind turbine 52. Similarly, the cross-sectional area of ​​the fourth air duct section 5112 refers to the area of ​​the cross-section obtained by cutting the fourth air duct section 5112 with a plane perpendicular to the axis of the second wind turbine 52.

[0092] According to some embodiments of the present invention, with reference to Figure 1 , Figure 2 , Figure 4 , Figures 8-10The first chamber 11 is located above the second chamber 21. A first air inlet 12 can be formed on the circumferential sidewall of the first chamber 11. For example, a second air inlet 22 can be formed on the left, right, and rear sidewall of the second chamber 21. A first air outlet 13 can be formed at the top of the first chamber 11. Thus, when the first fan unit 30 is operating, air can enter the first chamber 11 from the left, right, and rear sides. The air entering the first chamber 11 flows upward and is blown into the room through the first air outlet 13. The second air inlet 22 can be formed on the circumferential sidewall of the second chamber 21. For example, the second air inlet 22 can be formed on the left and right sidewalls of the second chamber 21. The second air outlet 23 can be formed on the circumferential sidewall of the second chamber 21. For example, the second air outlet 23 can be formed on the front sidewall of the second chamber 21. Therefore, when the second fan unit 50 is working, air can enter the second chamber 21 from the left and right sides, and the air entering the second chamber 21 flows forward and is blown into the room through the second air outlet 23.

[0093] This allows air to flow roughly horizontally into the first chamber 11 and the second chamber 21, preventing air pollution caused by bottom-level air intake from easily stirring up dust from the ground. Furthermore, it allows for airflow in different directions, including horizontal and upward airflow, expanding the air delivery angle and range. The airflow direction is also designed to prevent the airflow from easily stirring up dust from the ground and causing air pollution.

[0094] Optionally, an air intake grille can be installed at the first air inlet 12, an air intake grille can also be installed at the second air inlet 22, and an air outlet grille can be installed at the second air outlet 23.

[0095] According to some optional embodiments of the present invention, refer to Figure 1 , Figure 2 , Figure 4 , Figures 8-10The first air outlet 13 includes a first sub-air outlet 131 and a second sub-air outlet 132. The first sub-air outlet 131 can be formed on the top wall of the first chamber 11, and an air outlet grille can be provided at the first sub-air outlet 131. The second sub-air outlet 132 can be formed on the circumferential side wall of the first chamber 11, and the second sub-air outlet 132 can extend circumferentially along the first chamber 11 in a ring shape. An air outlet grille can also be provided at the second sub-air outlet 132. Thus, when the first fan unit 30 is working, part of the airflow entering the first chamber 11 can be driven to exit upwards from the first sub-air outlet 131, and another part of the airflow entering the first chamber 11 can exit outwards from the second sub-air outlet 132, thereby allowing the second air outlet 23 to exit in different directions, further expanding the air supply range of the entire unit and improving the working efficiency of the air handling unit 100.

[0096] In some embodiments of the present invention, reference is made to... Figure 1 , Figure 2 , Figure 4 , Figures 8-10 An air guide channel 14 extending circumferentially along the outer periphery of the first chamber 11 is formed. The air guide channel 14 is connected to the first chamber 11. The outlet of the air guide channel 14 constitutes a second sub-air outlet 132. The air guide channel 14 can extend in a ring shape along the circumference of the first chamber 11. An air outlet grille can be installed inside the air guide channel 14. The air outlet grille is connected to the upper and lower side walls of the air guide channel 14. The air guide channel 14 extends upwards at an angle from the inside (the inside refers to the direction near the center of the first chamber 11) to the outside (the outside refers to the direction away from the center of the first chamber 11), so that the air blown out of the first air outlet 13 can be directed upwards and diagonally upwards, which is beneficial for purifying the upper air of the indoor space.

[0097] In some embodiments of the present invention, reference is made to... Figure 1 , Figure 2 , Figure 4 , Figures 8-10The housing 10 may include a housing 101 and a top cover 102. The top of the housing 101 is open, and the top cover 102 may be detachably mounted on the top of the housing 101. A second air outlet 23 is formed on the top cover 102. The first purification module 41, which is arranged adjacent to the first air outlet 13, may be located between the top cover 102 and the first fan unit 30. By arranging the first air outlet 13 on the detachable top cover 102, the space inside the top cover 102 can be fully utilized, and it is convenient to clean and maintain the air outlet structure on the top cover 102. At the same time, by disassembling and assembling the top cover 102, it is also convenient to maintain the first air supply processing component in the first chamber 11. For example, the first air outlet 13 includes the aforementioned first sub-air outlet 131 and second sub-air outlet 132. The first sub-air outlet 131 is formed on the top wall of the top cover 102, and the outer peripheral portion of the top cover 102 forms the aforementioned air guide channel 14.

[0098] It should be noted that when the housing 10 includes the first sub-housing and the second sub-housing as described above, a portion of the housing 101 constitutes the second sub-housing, and the other portion of the housing 101 and the top cover 102 constitute the first sub-housing.

[0099] According to some embodiments of the present invention, with reference to Figure 1 and Figure 6 The electronic control unit 70 of the air handling unit 100 can be located in the second chamber 21, and the electronic control unit 70 can be adjacent to the second air inlet 22. By locating the electronic control unit 70 in the second chamber 21 and adjacent to the second air inlet 22, when the second fan unit 50 is working, the airflow entering from the second air inlet 22 can flow through the electronic control unit 70 to dissipate heat from the electronic control unit 70, thereby improving the reliability of the electronic control unit 70 and extending its service life.

[0100] According to some optional embodiments of the present invention, refer to Figure 1 and Figure 6In a front-to-back direction, the second fan unit 50, the second purification module 61, and the electronic control unit 70 can be arranged sequentially. The second air inlet 22 is formed on the left and right sides of the second chamber 21, and the second air outlet 23 is formed on the front side wall of the second chamber 21. An air inlet cavity 24 is defined between the electronic control unit 70, the second purification module 61, and the inner wall of the second chamber 21. The second air inlet 22 is formed on the left and right sides of the air inlet cavity 24 and communicates with the air inlet cavity 24. At least a portion of the second air inlet 22 is opposite to the electronic control unit 70. For example, the electronic control unit 70 and the first purification module 41 are spaced apart in the front-to-back direction. The front portion of the second air inlet 22 is opposite to the front portion of the air inlet cavity 24 located in front of the electronic control unit 70, and the rear portion of the second air inlet 22 is opposite to the electronic control unit 70. Therefore, the air entering the air intake chamber 24 from the second air inlets 22 on both sides can flow directly to the electronic control unit 70, carrying away the heat generated by the electronic control unit 70. It then flows to the second purification module 61, where it is purified. After being accelerated by the second impeller 52, it is blown vertically out of the second air outlet 23 into the room. This design allows the air entering from the second air inlets 22 to directly dissipate heat from the electronic control unit 70, improving heat dissipation effect and efficiency, while also making the structure compact.

[0101] Optionally, refer to Figure 4 and Figure 7 The second air handling unit 60 may also include a humidification module 62, which may include a humidification water tank 621 and a humidification element. The humidification water tank 621 is used to supply water to the humidification element, which may include a wet cotton. The humidification element and the first purification module 41 may be arranged in the direction of airflow, for example, the humidification element and the first purification module 41 may be arranged in the front-to-back direction, so that the second air handling unit 60 can realize the functions of purification and humidification.

[0102] In some embodiments of the present invention, reference is made to... Figure 1 and Figure 6 The electronic control unit 70 may include an electronic control box 71 and a heat sink 72. The heat sink 72 may be located on the front side of the electronic control box 71, and a heat dissipation duct 74 may be defined between the heat sink 72 and the electronic control box 71. The heat dissipation duct 74 is connected to the air inlet cavity 24. In this way, the air entering the air inlet cavity 24 from the second air inlet 22 can flow into the heat dissipation duct 74 and exchange heat with the electronic control box 71, carrying away the heat generated by the electronic control box 71, and then flowing out of the heat dissipation duct 74. It then flows sequentially through the second air handling unit 60 and the second fan unit 50, and is blown out into the room through the second air outlet 23. By setting the heat sink 72 on the front side of the electronic control box 71, and making the heat sink 72 define the heat dissipation duct 74 between the electronic control box 71 and the electronic control box 71, the heat dissipation efficiency of the electronic control box 71 can be further improved.

[0103] Among them, reference Figure 1 and Figure 6 The electrical control box 71 includes an electrical control box body 711 and an electrical control component 712 disposed on the electrical control box body 711. The electrical control component 712 includes an electrical control board. At least the portion of the electrical control box body 711 facing the heat dissipation duct 74 is made of metal, or the entire electrical control box body 711 can be made of metal. For example, the electrical control box body 711 can be a sheet metal part, and the heat dissipation plate 72 can be a metal plate, such as an aluminum plate. This further improves the heat dissipation efficiency of the electrical control box 71.

[0104] Optionally, refer to Figure 6 The heat sink 72 may include a flat plate 721 and multiple heat dissipation protrusions 722, and the heat sink 72 may be a one-piece molded part. The plate 721 may be arranged parallel to the left and right direction, and the multiple heat dissipation protrusions 722 are provided on the side of the plate 721 facing the heat dissipation duct 74. Each heat dissipation protrusion 722 is spaced apart from the front side of the electrical control box 71, so that the entire heat dissipation duct 74 is a continuous channel. Each heat dissipation protrusion 722 may be elongated and extend vertically. The multiple elongated heat dissipation protrusions 722 are arranged at intervals in the left and right direction. In this way, the airflow entering the air inlet cavity 24 from the second air inlet 22 flows into the heat dissipation duct 74. Since the heat sink 72 includes the above-mentioned multiple heat dissipation protrusions 722, the contact area between the airflow flowing into the heat dissipation duct 74 and the heat sink 72 can be increased, further improving the heat dissipation efficiency.

[0105] In some optional embodiments of the present invention, the heat sink 72 may have a plurality of ventilation holes (not shown) connecting the heat dissipation duct 74 and the air inlet cavity 24. When the heat sink 72 includes the aforementioned plate body 721 and heat dissipation protrusion 722, the ventilation holes are formed on the plate body 721, and the plate body 721 may be in the shape of a grid. The airflow entering the air inlet cavity 24 from the second air inlet 22 can enter the heat dissipation duct 74 through the plurality of ventilation holes, and then flow out of the heat dissipation duct 74 through the plurality of ventilation holes, thus facilitating the connection between the heat dissipation duct 74 and the air inlet cavity 24.

[0106] In some optional embodiments of the present invention, a communication port 73 is defined between the outer periphery of the heat sink 72 and the electrical control box 71, connecting the heat dissipation duct 74 and the air inlet cavity 24. The airflow entering the air inlet cavity 24 from the second air inlet 22 can enter the heat dissipation duct 74 through the communication port 73, and then flow out of the heat dissipation duct 74 through the communication port 73, thus conveniently realizing the connection between the heat dissipation duct 74 and the air inlet cavity 24.

[0107] For example, in some specific embodiments of the present invention, reference is made to... Figure 1 and Figure 6Multiple ventilation holes can be formed on the heat sink 72 to connect the heat dissipation air duct 74 and the air inlet cavity 24. The outer periphery of the heat sink 72 and the electrical control box 71 define a connection port 73 connecting the heat dissipation air duct 74 and the air inlet cavity 24. Specifically, the left edge of the heat sink 72 and the electrical control box 71 define a connection port 73, and the right edge of the heat sink 72 and the electrical control box 71 define a connection port 73. The left-side connecting port 73 and the left-side second air inlet 22 are opposite each other in the left-right direction. This allows air entering the air intake cavity 24 from the left-side second air inlet 22 to flow to the right and directly through the left-side connecting port 73 into the heat dissipation duct 74. At the same time, the right-side connecting port 73 and the right-side second air inlet 22 are opposite each other in the left-right direction. This allows air entering the air intake cavity 24 from the right-side second air inlet 22 to flow to the left and directly through the right-side connecting port 73 into the heat dissipation duct 74. This reduces the airflow path and the change in airflow direction, allowing the airflow to dissipate heat from the electrical control box 71 while flowing smoothly, reducing flow resistance and noise. After the airflow enters the heat dissipation duct 74 through the connecting ports 73 on the left and right sides and exchanges heat with the electrical control box 71, it flows out of the heat dissipation duct 74 from multiple vents on the heat dissipation plate 72 and flows into the front part of the air inlet cavity 24. Then the airflow flows through the second air handling unit 60 and the second fan unit 50 in sequence, and is blown out into the room through the second air outlet 23.

[0108] In some embodiments of the present invention, reference is made to... Figure 1 and Figure 6 The inner wall of the housing 10 is provided with a mounting bracket 80. Specifically, the rear side wall of the second chamber 21 is provided with a mounting bracket 80. The heat sink 72 is connected to the mounting bracket 80, which facilitates the installation and fixing of the heat sink 72. The electrical control box 71 can be connected and fixed to the heat sink 72.

[0109] Furthermore, referring to Figure 1 and Figure 6 The mounting bracket 80 may include two sub-mounting brackets 81 that are spaced apart from each other. The upper and lower ends of the heat sink 72 are respectively connected to the two sub-mounting brackets 81. The electrical control box 71 is located in the space defined by the two sub-mounting brackets 81 and the heat sink 72.

[0110] Optionally, a maintenance opening is formed on the portion of the housing 10 corresponding to the electrical control box 71, and a maintenance cover 90 is provided at the maintenance opening for opening and closing, thereby facilitating the maintenance of the electrical control box 71. When the aforementioned mounting bracket 80 is provided on the inner wall of the housing 10, the maintenance opening can be located between two sub-mounting brackets 81 of the mounting bracket 80.
