Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to an air handling device. Background Technology

[0002] With the improvement of people's living standards and the pursuit of a healthy environment, air handling units have become a necessity for many families. Air handling units use evaporative cooling pads to humidify and ventilate, thereby increasing indoor air humidity and improving the comfort of the living environment.

[0003] However, in the air handling equipment of the related technology, the air containing moisture after being humidified by the wet curtain component does not circulate smoothly within the internal space of the air handling equipment, which affects the humidification efficiency of the air handling equipment. Utility Model Content

[0004] This application discloses an air handling device that can more efficiently direct airflow from the air inlet to the air outlet, thereby improving the humidification efficiency of the air handling device.

[0005] To achieve the above objectives, this application discloses an air handling device, comprising: a housing with an air inlet and an air outlet, and a fan assembly and a wet curtain assembly disposed within the housing; a water tank, wherein the wet curtain assembly is detachably disposed within the water tank; a water supply assembly disposed within the housing, wherein the water supply assembly is used to supply water from the water tank to the wet curtain assembly; and an air inlet structure disposed within the housing, wherein the fan assembly and the wet curtain assembly are respectively located on both sides of the air inlet structure, the air inlet structure comprising a plurality of spaced-apart grille strips and a plurality of ventilation openings formed between adjacent grille strips, the ventilation openings being connected to the air inlet and the air outlet respectively.

[0006] In one possible implementation, the air intake structure protrudes away from the fan assembly so that the vent faces the wet curtain assembly.

[0007] In one possible implementation, the air intake structure includes a mounting section and an air intake portion located on the outer periphery of the mounting section, the water supply assembly is disposed in the mounting section, and the vent is formed in the air intake portion.

[0008] In one possible implementation, the air inlet includes a first end close to the fan assembly and a second end connected to the water supply assembly in the vertical direction;

[0009] The air inlet extends in a straight line from the first end to the second end, or the air inlet extends in a curve from the first end to the second end.

[0010] In one possible implementation, the projection of the grid strip along the vertical direction is a straight line.

[0011] In one possible implementation, the extensions of the plurality of the grille bars converge at the axis of the wind turbine assembly.

[0012] In one possible implementation, the spacing between any two adjacent grille bars is equal along the circumference of the air intake structure.

[0013] In one possible implementation, the evaporative cooling pad assembly includes an inner cavity, and the air inlet structure protrudes in a direction away from the fan assembly and extends at least partially into the inner cavity of the evaporative cooling pad assembly.

[0014] In one possible implementation, the air handling equipment further includes: a partition plate disposed on the housing, the fan assembly and the wet curtain assembly respectively located on both sides of the partition plate, the partition plate including a perforated portion, and the air inlet structure disposed on the perforated portion; the air inlet structure and the partition plate are an integral structure, or the air inlet structure and the water supply assembly are an integral structure.

[0015] In one possible implementation, a water distribution tray is provided on the top of the wet curtain assembly;

[0016] The partition plate includes a windbreak protruding towards the water storage tank. In the horizontal direction, the windbreak is located on the side of the water distribution plate opposite to the air inlet, and the lower edge of the windbreak is closer to the water storage tank than the top of the water distribution plate.

[0017] In one possible implementation, the windbreak includes a guide surface whose extension passes through the air intake structure and the air inlet, so as to guide the airflow entering from the air inlet to the air intake structure.

[0018] In one possible implementation, the partition plate further includes a baffle rib extending toward the water storage tank and extending into the water distribution tray.

[0019] In this way, the air intake structure effectively guides the airflow through the evaporative cooling pad assembly to the fan assembly, where the humidified airflow enters through multiple vents. The fan assembly further accelerates and pressurizes the airflow, allowing the humidified airflow to be discharged from the air handling unit with a greater head and more uniform diffusion, thereby improving the humidification range of the air handling unit and the uniformity of indoor air humidity. Furthermore, the grille bars prevent users from inserting their fingers into the fan assembly, providing safety protection.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0031] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0032] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0033] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0034] In related technologies, air handling equipment (e.g., humidifiers) typically includes a housing, a water tank, a evaporative cooling pad assembly, a water supply assembly, and a fan assembly. The water tank is installed inside the housing, which has an air inlet and an air outlet, with the air outlet located above the air inlet. The evaporative cooling pad assembly is located inside the housing and faces the air inlet. The water supply assembly draws water from the water tank and sprays it onto the mesh fabric. The airflow drawn in by the fan assembly flows from the air inlet to the air outlet; as it passes over the moistened evaporative cooling pad assembly, the moisture evaporates and is blown out with the airflow, thus humidifying the air.

[0035] However, in air handling equipment of related technologies, the airflow after being humidified by the wet curtain component is prone to airflow reversal and eddy currents as it flows towards the air outlet. This results in the humidified airflow not being effectively diffused into the indoor environment, thereby reducing the overall performance of the air handling equipment.

[0036] Based on this, the present application provides an air handling device that can improve the smoothness of the humidified airflow in the air handling device, increase the head and diffusion effect of the humidified airflow, and thus improve the overall performance of the air handling device.

[0037] Please refer to the following: Figure 1 and Figure 2 This application provides an air handling device 100, which includes a housing 10, a water tank 80, a fan assembly 20, and a wet curtain assembly 30. The housing 10 has an air inlet 101 and an air outlet 102, forming an airflow channel 10a between the air inlet 101 and the air outlet 102. The fan assembly 20 and the wet curtain assembly 30 are both located within the airflow channel 10a. The airflow entering from the air inlet 101 passes through the wet curtain assembly 30, and the humidified wet curtain assembly 30 increases the humidity of the airflow. The humidified airflow is accelerated and pressurized by the fan assembly 20 and flows out of the air handling device 100 from the air outlet 102 to humidify the indoor environment.

[0038] In some embodiments, such as Figure 1 and Figure 2 As shown, the air inlet 101 includes multiple air holes. The air inlet 101 is disposed on the side wall of the housing 10 and surrounds the outer perimeter of the housing 10. Along the height direction of the air handling equipment 100, that is, the vertical direction, the evaporative cooling pad assembly 30 is located inside the housing 10 and is disposed approximately corresponding to the multiple air inlets 101, so that the airflow entering the air inlet 101 can have as much gas-liquid contact with the evaporative cooling pad assembly 30 as possible.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the housing 10 includes an air outlet 102. The air outlet 102 can communicate with the exhaust port of the fan housing 201 of the fan assembly 20. The air outlet 102 is located at the top of the housing 10 to provide a greater head for the humidified airflow when it is blown into the room.

[0040] In some embodiments, such as Figure 2 As shown, the air handling unit 100 may include a water supply assembly 40. The water supply assembly 40 includes a water pump for drawing water from the water storage tank 80 and spraying it into the wet curtain assembly 30.

[0041] In some embodiments, such as Figure 5As shown, the evaporative cooling pad assembly 30 may include a mesh fabric 303, which has water storage capacity to store water sprayed in by the water supply assembly 40. The wet mesh fabric 303 can humidify the airflow. The water outlet of the water supply assembly 40 can be located at the top of the evaporative cooling pad assembly 30, so that water can evenly wet the evaporative cooling pad assembly 30 based on gravity.

[0042] Mesh fabric 303, also known as a wet curtain, can comprise a wettable filter media made of hydrophilic polymer composite materials or natural / synthetic fiber fabrics. The surface of the wettable filter media can be treated with a nano-coating or gradient porosity to optimize capillary water absorption performance. The wettable filter media forms a high specific surface area air-water contact interface through a multi-layer composite or three-dimensional honeycomb structure, and is equipped with antibacterial agents or anti-mildew coatings to resist biofouling. The wettable filter media can also incorporate a support frame integrating guide channels or asymmetric corrugated units to directionally guide airflow and moisture diffusion paths. Furthermore, mesh fabric 303 can be a modular assembly structure of the wettable substrate, adaptable to detachable installation interfaces with different assembly requirements.

[0043] In some embodiments, such as Figure 2 As shown, the wet curtain assembly 30 can be mounted on the water storage tank 80, which facilitates separation from the water storage tank 80 for cleaning, and also facilitates the return of water overflowing from the wet curtain assembly 30 to the water storage tank 80.

[0044] In some embodiments, such as Figure 2 and Figure 3 As shown, the air handling unit 100 may include an air inlet structure 50. The air inlet structure 50 may be directly or indirectly fixed to the housing 10 and located inside the housing 10. Along the height direction of the air handling unit 100, the fan assembly 20 and the evaporative cooling pad assembly 30 are respectively located on both sides of the air inlet structure 50.

[0045] In some embodiments, the air intake structure 50 may be located in the central region of the housing 10. This results in a more balanced and smoother airflow within the airflow channel 10a.

[0046] In some embodiments, such as Figure 2 As shown, the fan assembly 20 may include a fan housing 201. An air inlet structure 50 may be connected to the air inlet 203 of the fan housing 201 to increase the airflow rate entering the fan assembly 20 from the air inlet structure 50 and reduce airflow loss.

[0047] In some embodiments, such as Figure 3 As shown, the air inlet 502 may include a plurality of spaced-apart grille bars 504. Ventilation openings 503 are formed between adjacent grille bars 504. The plurality of ventilation openings 503 are respectively connected to the air inlet 101 and the air outlet 102. The ventilation openings 503 may be constructed as circular holes, strips, or other shapes; this embodiment does not limit this.

[0048] Thus, the air intake structure 50 effectively guides the airflow through the wet curtain assembly 30 to the fan assembly 20, where the humidified airflow enters the fan assembly 20 through multiple vents 503. The fan assembly 20 further accelerates and pressurizes the airflow, allowing the humidified airflow to be discharged from the air handling unit 100 from the air outlet 102 with a greater head and more uniform diffusion effect, thereby improving the humidification range of the air handling unit 100 and the uniformity of indoor air humidity. In addition, the grille strip 504 can also prevent users' fingers from entering the fan assembly 20, forming a safety protection.

[0049] In some embodiments, such as Figure 2 and Figure 3 As shown, the air inlet structure 50 may include a mounting portion 501 and an air inlet portion 502. The mounting portion 501 is located in the central region of the air inlet structure 50, and the air inlet portion 502 is located on the outer periphery of the mounting portion 501. The air inlet portion 502 is used to mount the water supply assembly 40 and to allow humidified airflow to pass through.

[0050] In some embodiments, such as Figure 2 and Figure 3 As shown, the air inlet 502 is located on the outer periphery of the mounting portion 501, which is used to install the water supply assembly 40, so that the water supply assembly 40 can be located in the central area of ​​the air handling unit 100. The water supply assembly 40 can pass through the inner cavity of the wet curtain assembly 30 and is at least partially placed in the water storage tank 80.

[0051] Unlike related technologies where the water supply component is located on the outer periphery of the wet curtain component, i.e., between the wet curtain component and the outer shell, the water supply component 40 in this embodiment does not block the air inlet 101 on the outer shell 10, so as to increase the flow rate of airflow from the air inlet 101 into the airflow channel 10a.

[0052] like Figure 2 and Figure 3 As shown, the mounting portion 501 can be a hollow area, and at least a portion of the water supply component 40 can extend into the mounting portion 501. Alternatively, the mounting portion 501 can be a mounting plate, and the water supply component 40 is assembled into the mounting portion 501.

[0053] In some embodiments, such as Figure 2 As shown, the air inlet 502 surrounds the entire outer periphery of the mounting portion 501. The air inlet 502 can provide comprehensive ventilation along the circumference of the air handling unit 100, reducing vibration or noise caused by uneven airflow distribution and improving the user experience.

[0054] It should be noted that the water supply component 40 is installed in the mounting section 501. That is, the water supply component 40 is located in the central area of ​​the air intake structure 50 / air handling unit 100. In this way, the overall center of gravity of the air handling unit 100 will be more balanced and stable, and it will not be easy to tilt or tip over. Moreover, the air intake section 502 is located on the outer periphery of the mounting section 501, and airflow can pass through the air intake section 502. Therefore, the water supply component 40 will not affect the humidification effect of the air handling unit 100. At the same time, the air intake structure 50 can be used for air passage and also provide structural support for the water supply component 40, optimizing the internal structural layout of the air handling unit 100, reducing the number of structural components, and making the structure of the air handling unit 100 more compact.

[0055] It is understandable that, since the impeller 202 in the fan assembly 20 will generate negative pressure during rotation, the fan assembly 20 and the wet curtain assembly 30 are located on both sides of the air inlet structure 50. This means that the air inlet 502 is located in the area with strong negative pressure at the air inlet of the fan assembly 20, and the wind pressure generated by the negative pressure suction of the airflow is concentrated in the air inlet 502.

[0056] In this way, the air inlet 502 can effectively guide the airflow to concentrate on the fan assembly 20, and the humid airflow can enter the fan assembly 20 through the air inlet 502 at a higher speed and pressure. The fan assembly 20 further accelerates and pressurizes the airflow, so that the humidified airflow can be discharged from the air outlet 102 from the air handling unit 100 with a greater head and a more uniform diffusion effect, thereby improving the humidification range of the air handling unit 100 and the uniformity of indoor air humidity.

[0057] It is worth noting that, along the height of the air handling unit 100, the air inlet structure 50 is located between the evaporative cooling pad assembly 30 and the fan assembly 20. The top of the evaporative cooling pad assembly 30 is closer to the air inlet 502. Because the air pressure is concentrated at the air inlet 502, the airflow efficiency at the top of the evaporative cooling pad assembly 30 is relatively higher. Figure 2 As shown, the airflow efficiency of the evaporative cooling pad assembly 30 decreases from the upper to the lower layers (more air enters the air handling unit 100 through the curved air intake path located at the upper layer). Furthermore, since the water outlet of the water supply assembly 40 faces the top of the evaporative cooling pad assembly 30, the water storage capacity at the top of the evaporative cooling pad assembly 30 is relatively higher than at the bottom. Combined with the higher airflow efficiency at the top of the evaporative cooling pad assembly 30, the humidification efficiency of the airflow is improved, allowing the air handling unit 100 to increase the indoor air humidity more quickly and efficiently. Simultaneously, while the humidity at the bottom of the evaporative cooling pad assembly 30 may be relatively lower than at the top, the airflow efficiency through the evaporative cooling pad assembly 30 is also relatively lower. This allows the evaporative cooling pad assembly 30 to maintain relatively consistent humidity across its various parts, achieving a dynamic balance of moisture within the evaporative cooling pad assembly 30.

[0058] In addition to ventilation, the air inlet structure 50 also prevents users' fingers from entering the fan assembly 20. Specifically, the water supply assembly 40 can be connected to the housing 10 through the air inlet structure 50. When it is necessary to clean the water storage tank 80 and the wet curtain assembly 30, the water supply assembly 40 can be separated from the water storage tank 80 by lifting the housing 10 upwards. As long as the shape and size of the vent 503 are properly designed, the air inlet 502 located at the air inlet of the fan assembly 20 can block the user's fingers, preventing the user's fingers from accidentally entering the fan assembly 20, thereby improving the safety of using the air handling equipment 100.

[0059] Thus, the air handling equipment 100 provided in this application embodiment, by setting the air inlet structure 50 between the fan assembly 20 and the wet curtain assembly 30, and with the air inlet 502 located in the area of ​​strong negative pressure of the fan assembly 20, can effectively guide the humidified airflow to enter the fan assembly 20 through the air inlet 502 at a higher speed and pressure, thereby enhancing the airflow head and diffusion effect, and the air handling equipment 100 can achieve efficient and stable humidification performance.

[0060] In some embodiments, such as Figure 2 As shown, the air inlet 502 protrudes in a direction away from the fan assembly 20 so that the vent 503 faces the wet curtain assembly 30.

[0061] If the air inlet 502 is constructed as a flat plate extending horizontally, the vent 503 will face the bottom of the air handling unit 100, i.e., towards the water tank 80. In this case, the airflow entering from the air inlet 101 will easily impact the water supply assembly 40 located inside the evaporative cooling pad assembly 30, causing the airflow to veer and create eddies. In this embodiment, the air inlet 502 of the air handling unit 100 protrudes away from the fan assembly 20, allowing the vent 503 formed in the air inlet 502 to face the air inlet 101 located on the side wall of the housing 10 as much as possible. This effectively increases the effective airflow angle range of the air inlet 502, allowing the airflow to enter the air inlet 502 more smoothly after passing through the evaporative cooling pad assembly 30. This optimizes the airflow path, reduces the possibility of airflow veering or creating eddies before entering the fan assembly 20, and thus improves the overall efficiency and airflow stability of the air handling unit 100.

[0062] In some embodiments, the air inlet 502 includes a first end close to the fan assembly 20 and a second end away from the fan assembly 20 in a vertical direction, and the air inlet 502 extends in a straight line from the first end to the second end.

[0063] The air inlet 502 includes a first end close to the fan assembly 20 and a second end away from the fan assembly 20, that is, the air inlet 502 is inclinedly disposed inside the housing 10. Since the air outlet 102 is usually located at the top of the housing 10, the inclined disposal of the air inlet 502 not only allows the vent 503 located in the air inlet 502 to face the air inlet 101 located on the side wall of the housing 10, but also allows the vent 503 to face the air outlet 102 located at the top of the housing 10, thus optimizing the airflow path and reducing the risk of turbulence.

[0064] In some embodiments, the air inlet 502 includes a first end close to the fan assembly 20 and a second end away from the fan assembly 20 in a vertical direction, and the air inlet 502 extends in a curve from the first end to the second end.

[0065] The air inlet 502 extends in a curve from the first end to the second end, that is, the air inlet 502 has an arc-shaped curved surface. While the air inlet 502 faces the air inlet 101 and the air outlet 102, the air inlet 502 extends in a curve from the first end close to the fan assembly 20 to the second end away from the fan assembly 20, which can further reduce the impact of airflow on the air inlet 502, reduce the generation of eddies, and reduce the operating noise of the air handling equipment 100.

[0066] In some embodiments, such as Figure 3 As shown, multiple vents 503 are arranged at intervals along the circumference of the mounting portion 501, and the air inlet portion 502 between adjacent vents 503 forms a grille strip 504.

[0067] Multiple vents 503 provided in the air inlet 502 are spaced apart circumferentially along the mounting portion 501, enabling the humidified airflow to be evenly discharged from multiple directions. The portion of the air inlet 502 located between the vents 503 forms a grille 504, which can prevent the user's fingers from getting in.

[0068] In some embodiments, such as Figure 3 As shown, multiple grille bars 504 can be set at equal intervals, that is, the circumferential spacing between adjacent grille bars 504 can be approximately equal, so that the airflow can flow in evenly from the air inlet 502 in the circumference, reducing the risk of local airflow concentration or dispersion.

[0069] In some embodiments, such as Figure 3 As shown, the projection of the grille bars 504 in the vertical direction is a straight line. The airflow from the wet curtain assembly 30 into the fan assembly 20 can pass through the grille bars 504. The grille bars 504 do not interfere with or block the upward airflow, allowing the airflow to enter the fan assembly 20 smoothly.

[0070] In some embodiments, such as Figure 3As shown, the extended lines of the grille bars 504 converge at the axis of the fan assembly 20, which means that the central axis of the air inlet 502 coincides with the central axis of the fan assembly 20. This helps the air inlet 502 guide the airflow more evenly into the fan assembly 20, reducing energy loss. The grille bars 504 are distributed outward from the axis of the fan assembly 20. The divergent distribution of the grille bars 504 can evenly distribute stress and improve the deformation resistance of the air inlet 502.

[0071] In some embodiments, such as Figure 2 As shown, the air inlet 502 extends into the inner cavity of the wet curtain assembly 30. This allows the vent 503 of the air inlet 502 to face the air inlet 101 located on the side wall of the housing 10 as much as possible, further increasing the effective airflow angle range of the air inlet 502, so that the airflow can enter the air inlet 502 more smoothly after passing through the wet curtain assembly 30.

[0072] In some embodiments, such as Figure 2 and Figure 3 As shown, the air handling unit 100 may further include a partition plate 103. The partition plate 103 is located inside the housing 10 and is disposed on the housing 10. The fan assembly 20 and the evaporative cooling pad assembly 30 are respectively located on both sides of the partition plate 103. The partition plate 103 divides the interior of the housing 10 into a fan chamber 104 for accommodating the fan assembly 20 and a humidification chamber 105 for accommodating the evaporative cooling pad assembly 30. The fan chamber 104 communicates with the air outlet 102, and the humidification chamber 105 communicates with the air inlet 101.

[0073] In some embodiments, such as Figure 3 As shown, the partition plate 103 has a hollow portion 1031 in the middle, and the air inlet structure 50 is installed in the hollow portion 1031 of the partition plate 103. Specifically, the air inlet structure 50 can be connected to the hollow portion 1031 of the partition plate 103 through a support ring. That is, the support ring of the air inlet structure 50 can be connected to both the partition plate 103 and the fan assembly 20 to further reduce the flow loss when the airflow flows into the fan assembly 20.

[0074] In some embodiments, the outer periphery of the partition plate 103 is sealed to the outer casing 10, or the partition plate 103 and the outer casing 10 are an integral structure. In this way, the airflow through the wet curtain assembly 30 can only flow into the fan assembly 20 from the air inlet 502 of the air inlet structure 50, further concentrating the airflow pressure in the outer casing 10 in the air inlet 502, reducing the risk of airflow dispersion and the formation of eddies.

[0075] In some embodiments, the air intake structure 50 and the water supply component 40 are integrated. In this way, the water supply component 40 can be stably installed on the partition plate 103 through the integrally formed air intake structure 50, which reduces the assembly process of the air intake structure 50 and the water supply component 40 and improves the assembly efficiency of the air handling equipment 100.

[0076] In some embodiments, the air inlet structure 50 and the partition plate 103 are an integral structure. The mounting part 501 can be sealed to the water supply assembly 40 to seal the connection gap between the two, so as to prevent airflow from generating noise through the gap.

[0077] In some embodiments, such as Figure 4 and Figure 5 As shown, a water distribution plate 302 is provided on the top of the evaporative cooling pad assembly 30. The water distribution plate 302 is used to receive water flowing out from the outlet end of the water supply assembly 40. The water distribution plate 302 is provided with a water outlet hole to facilitate water flow into the evaporative cooling pad assembly 30.

[0078] In some embodiments, such as Figure 5 As shown, the evaporative cooling pad assembly 30 includes a frame 301 and a mesh fabric 303 disposed on the frame 301. The frame 301 provides structural support for the mesh fabric 303.

[0079] In some embodiments, such as Figure 2 and Figure 4 As shown, the partition plate 103 includes a windbreak portion 1032 protruding toward the water storage tank 80. The lower edge of the windbreak portion 1032 is closer to the water storage tank 80 than the top of the water distribution plate 302.

[0080] After the evaporative cooling pad assembly 30 overlaps with the water storage tank 80, and the outer casing 10 covers the outside of the water storage tank 80 to complete the assembly of the air handling unit 100, there may be a small assembly gap between the evaporative cooling pad assembly 30 and the partition plate 103. In order to reduce the airflow entering the interior of the outer casing 10 from the air inlet 101, which flows in through the gap between the water distribution plate 302 and the partition plate 103 without passing through the wetted mesh 303, the humidification efficiency of the airflow is reduced. The partition plate 103 has a windbreak portion 1032 that protrudes outward from the water storage tank 80. In the horizontal direction, the windbreak portion 1032 is located on the side of the water distribution plate 302 away from the air inlet 101. The lower edge of the windbreak portion 1032 is closer to the water storage tank 80 than the top of the water distribution plate 302. In this way, the windbreak portion 1032 forms a physical barrier, reducing the occurrence of airflow directly bypassing the mesh 303 through the gap between the water distribution plate 302 and the partition plate 103. This ensures that most of the airflow flowing into the outer casing 10 through the air inlet 101 is humidified by the mesh 303, thereby improving humidification efficiency.

[0081] In some embodiments, such as Figure 2 and Figure 4As shown, the windbreak 1032 includes a guide surface 1033. The extension of the guide surface 1033 passes through the air inlet 502, the mesh 303 and the air inlet 101 to guide the airflow entering from the air inlet 101 to the air inlet 502.

[0082] The wind deflector 1032 has an air guide surface 1033. The extension of the air guide surface 1033 passes through the air inlet 502, the mesh 303 and the air inlet 101, so that the airflow can be guided by the air guide surface 1033 to the air inlet 502 in the area of ​​concentrated wind pressure after entering the outer shell 10, thereby reducing the disorderly diffusion of airflow inside the outer shell 10 and improving the humidification efficiency.

[0083] In some embodiments, the air guide surface 1033 may include a curved surface to effectively guide airflow.

[0084] Specifically, one side wall of the windbreak 1032 can be connected to the air inlet 502, and the air guide surface 1033 is formed on the side of the windbreak 1032 near the air inlet 502.

[0085] In some embodiments, such as Figure 2 and Figure 4 As shown, the partition plate 103 is provided with a baffle 1034, which extends toward the water storage tank 80 and into the water distribution plate 302.

[0086] The baffle 1034 can be located on the side of the windbreak 1032 near the air inlet 101. The baffle 1034 extends into the water distribution plate 302, which is equivalent to forming a barrier for the airflow entering the gap between the water distribution plate 302 and the partition plate 103 before the windbreak 1032, so as to reduce the occurrence of airflow flowing into the air inlet 502 without passing through the mesh 303.

[0087] In some embodiments, such as Figure 5 As shown, the water distribution plate 302 includes a first sidewall 3021 and a second sidewall 3022, with a water passage located between the first sidewall 3021 and the second sidewall 3022. The second sidewall 3022 is closer to the windbreak portion 1032 than the first sidewall 3021.

[0088] In the vertical direction, the lower edge of the baffle 1034 is located between the upper edge of the first sidewall 3021 and the upper edge of the second sidewall 3022. The lower edge of the baffle 1034 is lower than the upper edge of the second sidewall 3022, which is equivalent to forming an air seal between the baffle 1034 and the second sidewall 3022, so as to further reduce the occurrence of airflow flowing into the air inlet 502 without passing through the mesh 303, and increase the airflow through the mesh 303.

[0089] In some embodiments, such as Figure 2As shown, the water tank 80 is located at the bottom of the air handling unit 100. The evaporative cooling pad assembly 30 is detachably mounted on the water tank 80.

[0090] Specifically, the water storage tank 80 may include a tank body 802 and a water receiving tray 801. The water receiving tray 801 is located on the top of the tank body 802, and the wet curtain assembly 30 is detachably disposed on the water receiving tray 801. The water receiving tray 801 provides structural support for the wet curtain assembly 30.

[0091] In some embodiments, the water receiving tray 801 is provided with water permeable holes so that water overflowing from the wet curtain assembly 30 flows back to the water storage tank 80.

[0092] In some embodiments, the wet curtain assembly 30 can be attached to the water receiving tray 801 of the water storage tank 80 to facilitate the disassembly and assembly of the wet curtain assembly 30 and the water storage tank 80.

[0093] In some embodiments, the bottom of the outer casing 10 is open, and the outer casing 10 is fitted onto the outside of the water storage tank 80 or overlapped on the top of the water outlet tank 80 through the open end, and is separable from the water storage tank 80. The outer casing 10 covers the outside of the water storage tank 80 by fitting, and there may be an assembly gap between the outer casing 10 and the water storage tank 80, or the outer casing 10 contacts and forms an abutment relationship with at least a portion of the outer wall of the water storage tank 80, so as to increase the structural stability between the outer casing 10 and the water storage tank 80. Alternatively, the water storage tank 80 and the wet curtain assembly 30 are simultaneously overlapped on the top of the water tank 80, so as to facilitate separation from the water tank 80.

[0094] In some embodiments, a connection structure (such as snap-fit ​​or locking connection) that requires disassembly may not be provided between the housing 10 and the water tank 80. Thus, when the water tank 80 needs cleaning, simply lifting the housing 10 allows for easy separation of the water tank 80 from the housing 10, making the water tank 80 and the evaporative cooling pad assembly 30 visible to the user. The user can then directly place the water tank 80 and the evaporative cooling pad assembly 30 into a sink or dishwasher for cleaning. During assembly, simply placing the evaporative cooling pad assembly 30 on the water tank 80 and then covering the water tank 80 with the housing 10 improves the ease of disassembly and assembly of the air handling unit 100 when cleaning is required.

[0095] Since the electrical components (e.g., water supply assembly 40, fan assembly 20, electrical control box 60, etc.) are housed in the outer casing 10, the water supply assembly 40 can be separated from the water storage tank 80 when the outer casing 10 is separated from the water storage tank 80. The top of the water storage tank 80 can be opened, and when the outer casing 10 is covering the outside of the water storage tank 80, the water supply assembly 40 can extend into the interior of the water storage tank 80. There is no connection between the water supply assembly 40 and the water storage tank 80, and the water storage tank 80 does not require an installation structure for mounting the water supply assembly 40, thus eliminating any hard-to-clean areas inside the water storage tank 80. When it is necessary to clean the water storage tank 80 or add water to the water storage tank 80, simply lift the water storage tank 80 upwards, and the water supply assembly 40 will separate from the water storage tank 80, making the operation simple and quick.

[0096] Furthermore, since the water supply component 40 is fixed to the housing 10, the power interface of the water supply component 40 is fixed on the housing 10. When the water supply component 40 is inserted into the water storage tank 80, there is no need to align the power interface as in the water pump of the air handling equipment in the related technology, which further improves the assembly convenience between the water supply component 40, the housing and the water storage tank 80.

[0097] It should be noted that in this embodiment, the electrical components are centrally fixed to the outer casing 10, achieving water and electricity separation in the air handling unit 100. The water storage tank 80 and the evaporative cooling pad assembly 30, which come into contact with water, are independent of the electrical components, reducing the risk of water-electricity contact and improving the safety and reliability of the air handling unit 100. Simultaneously, the water-electricity separation design makes cleaning the water storage tank 80 and the evaporative cooling pad assembly 30 more convenient; they can be directly soaked in water for cleaning or washed separately in a dishwasher, enhancing the user experience.

[0098] Thus, the air handling unit 100 provided in this application embodiment, by centrally housing the electrical components in the outer casing 10, allows for easy separation between the outer casing 10, the water storage tank 80, and the evaporative cooling pad assembly 30. The water supply assembly 40, which has no direct connection to the water storage tank 80, can also be easily installed and removed from it. The air handling unit 100 achieves separation of water and electricity, convenient installation and removal, and efficient cleaning, thereby improving the safety, reliability, and user experience of the air handling unit 100.

[0099] In some embodiments, such as Figure 3 As shown, the electrical components of the air handling unit 100 include an electrical control box 60, which is located inside the fan chamber 104 and is connected to the fan assembly 20 and the water supply assembly 40.

[0100] By placing the electrical control box 60 inside the fan cavity 104, the water-electricity separation design of the air handling equipment 100 is further optimized, reducing the risk of the electrical control box 60 coming into direct contact with water, thereby reducing the risk of the circuit getting damp or short-circuited, and improving the safety and reliability of the air handling equipment 100.

[0101] In some embodiments, such as Figure 5 As shown, the frame 301 is typically constructed as a mesh structure and is cylindrical. An annular mesh 303 covers the outer periphery of the frame 301 to correspond to the air inlets provided on the sidewalls of the housing 10.

[0102] 303 mesh fabric is typically made of highly absorbent and tensile-resistant fibers or special composite materials, such as polyester fibers and nylon fibers. 303 mesh fabric can quickly absorb and retain moisture. When airflow passes through it, gas-liquid contact is achieved, creating a humidified airflow to increase indoor humidity.

[0103] In some embodiments, the mesh fabric 303 can be a multi-layer structure. This provides good water retention and increases the surface area for gas-liquid contact, thereby improving the humidification efficiency of the mesh fabric 303.

[0104] In some embodiments, such as Figure 5 As shown, a water distribution plate 302 is provided on the top of the frame 301. The water distribution plate 302 can inject water into the mesh 303.

[0105] Specifically, the water distribution tray 302 is located on the top of the frame 301, and the outlet end of the water injection pipe for humidifying the air handling unit 100 faces the water distribution tray 302. When water flows out from the water injection pipe, it first enters the water distribution tray 302 instead of flowing directly into the mesh fabric 303. The water distribution tray 302 can evenly disperse and guide the water flow to various areas of the mesh fabric 303, so that the water flow will not concentrate in a certain area of ​​the mesh fabric 303, but will evenly cover the entire mesh fabric 303, thereby reducing the occurrence of local over-wetting or over-drying of the mesh fabric 303.

[0106] It is understandable that by evenly injecting water into the mesh fabric 303 through the water distribution plate 302, sufficient water is held in all areas of the mesh fabric 303, thereby improving the humidification efficiency and effect of the mesh fabric 303. If the water holding capacity of a certain area of ​​the mesh fabric 303 is insufficient, even if airflow passes through that area, effective gas-liquid exchange cannot occur, resulting in energy waste and reducing the humidification effect of the air handling unit 100.

[0107] Furthermore, the mesh fabric 303 has high water absorption, allowing it to quickly absorb and retain moisture. When water flows through the injection pipe into the water distribution plate 302 and onto the mesh fabric 303, the mesh fabric 303 buffers the impact of the water flow, achieving silent absorption and reducing splashing and vibration noise generated during water injection. Related technology involves directly injecting water into the storage tank 80 via the injection pipe, which significantly reduces splashing and vibration noise.

[0108] In some embodiments, such as Figure 2 As shown, the wet curtain assembly 30 can be attached to the water storage tank 80 to facilitate the disassembly and assembly of the wet curtain assembly 30 and the water storage tank 80.

[0109] In some embodiments, the water tank 80 may include a water storage chamber. Water overflowing from the evaporative cooling pad assembly 30 may flow into the water tank 80.

[0110] Specifically, the housing 802 has a water storage cavity, and the water receiving tray 801 is located on top of the housing 802. The evaporative cooling pad assembly 30 is detachably mounted on the water receiving tray 801, which provides structural support for the evaporative cooling pad assembly 30. When the water holding capacity of the evaporative cooling pad assembly 30 reaches its upper limit, the excess water will overflow from the evaporative cooling pad assembly 30. The water receiving tray 801 may be provided with water guiding holes to allow the overflowing water from the evaporative cooling pad assembly 30 to flow into the water storage section of the water storage tank 80.

[0111] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
