[0043] The embodiments of this utility model 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 this utility model, and should not be construed as limiting this utility model.

[0044] The following is for reference. Figures 1-9 This invention describes an air conditioner according to an embodiment of the present invention.

[0045] refer to Figures 1-2 An air conditioner according to an embodiment of the present invention includes: a housing, a heat exchange and air supply unit, and an air handling unit 100.

[0046] The casing has an air inlet structure and an air outlet structure. The heat exchange and air supply unit is located inside the casing, and the air handling unit 100 is located inside the casing and below the heat exchange and air supply unit.

[0047] The casing serves to prevent dust and protect internal components. The air intake structure on the casing is used to bring indoor or outdoor air into the casing, while the air exhaust structure is used to exhaust the treated air into the room.

[0048] The heat exchange air supply unit is used to heat or cool the air supplied from the inlet structure and discharge it from the outlet structure. During cooling, water vapor in the air easily condenses on the heat exchange air supply unit. The heat exchange air supply unit may include a heat exchanger assembly and a first fan assembly. The first fan assembly drives indoor air from the inlet structure into the casing, where it exchanges heat with the heat exchanger assembly and is then discharged from the outlet structure into the room, thereby regulating the indoor temperature. The heat exchange air supply unit may also include a condensate tray located below the heat exchanger assembly to collect condensate generated on the heat exchanger assembly and / or the first fan assembly.

[0049] The air handling unit 100 is used to humidify or purify the air supplied to the air handling unit 100 from the air intake structure and discharge it from the air outlet structure. For example, the air handling unit 100 may include at least one of the functions of fresh air function, humidification function and purification function. The air handling unit 100 may include a second fan 42 assembly 40, which is used to introduce indoor air and / or outdoor air into the casing, process it and discharge it to the room through the air outlet structure, thereby improving indoor air quality. The second fan 42 assembly 40 may include a fan volute 41 and a second fan 42. The fan volute 41 has a fan duct 43, an air inlet 47 and an air outlet 48. The second fan 42 drives the airflow from the air intake structure and the air inlet 47 into the fan volute 41, and then discharges it to the room from the air outlet 48 and the air outlet structure.

[0050] When the air handling unit 100 has a fresh air function, the airflow inlet 47 may include a first airflow inlet 47147 communicating with the outdoor environment. The airflow inlet 47 may also include a second airflow inlet 47247 communicating with the indoor environment. When the air handling unit 100 has a humidification function, the air handling unit 100 may include a wet film and a water tank 50. The wet film is disposed within the fan duct 43, and the water tank 50 is used to supply water to the wet film. The wet film may be located upstream of the second fan 42. When the air handling unit 100 has a purification function, the air handling unit 100 may include a purification component, which may be disposed within the fan duct 43.

[0051] For example, the air intake structure may include a first air intake structure and a second air intake structure, and the air outlet structure may include a first air outlet structure and a second air outlet structure. Airflow inlet 47 is connected to the second air intake structure, and airflow outlet 48 is connected to the second air outlet structure. The heat exchange air supply unit drives indoor air from the first air intake structure into the casing to exchange heat with the heat exchanger components, and then discharges it to the room through the first air outlet structure, thereby regulating the indoor temperature. The air handling unit 100 drives indoor air and / or outdoor air through the second air intake structure and airflow inlet 47 into the air handling unit 100. After being processed by the air handling unit 100, the air is discharged to the room through the airflow outlet 48 and the second air outlet structure.

[0052] The second air intake structure may include an indoor air intake and a fresh air intake. The airflow inlet 47 includes a first airflow inlet 47147 and a second airflow inlet 47247 that are separated from each other. The first airflow inlet 47147 is connected to the fresh air intake, and the second airflow inlet 47247 is connected to the indoor air intake.

[0053] The air handling unit 100 has a water-collecting top cover 10 with a water-collecting trough 20 formed on it. The water-collecting top cover 10 of the air handling unit 100 is used to collect condensate generated and dripping from the heat exchange air supply unit. This can collect the condensate dripping from the heat exchange air supply unit, preventing or reducing the safety hazards caused by the condensate dripping from the heat exchange air supply unit onto other live parts, or preventing or reducing the safety hazards caused by the condensate dripping from the heat exchange air supply unit onto the air handling unit 100 flowing downwards onto live parts.

[0054] In addition, the condensate collected in the water collection tank 20 of the water collection top cover 10 can also be used, for example, to humidify the air in the air handling unit 100.

[0055] Optionally, the air conditioner can be a split-type air conditioner, which includes an indoor unit and an outdoor unit, wherein the indoor unit includes the aforementioned casing, heat exchange and air supply unit, and air handling unit 100. For example, the indoor unit can be mounted vertically on a wall.

[0056] According to the embodiment of the present invention, the air conditioner has a water-receiving top cover 10 and a water-receiving trough 20 provided on the top of the air handling unit 100. The water-receiving trough 20 can receive the condensate dripping down from the heat exchange and air supply unit located above. This can reduce the safety hazards caused by the condensate dripping down from the heat exchange and air supply unit to live parts and enhance the safety of the air conditioner's operation.

[0057] refer to Figure 1 According to some embodiments of the present invention, the heat exchange air supply unit includes a water receiving tray located on the bottom surface, a water receiving top cover 10 located below the water receiving tray, and at least a portion of the projection of the water receiving tray on the horizontal plane is located within the projection of the water receiving trough 20 on the horizontal plane.

[0058] For example, a heat exchange air supply unit may include a heat exchange air supply component and a water collection tray. The heat exchange air supply unit may include a heat exchanger component and a first fan component. The heat exchanger component is used to cool the air, and the first fan component is used to drive the air in or out. The water collection tray may be located below the heat exchange air supply component to facilitate the collection of condensate generated by the heat exchange air supply unit during cooling.

[0059] At least a portion of the projection of the water receiving tray onto the horizontal plane lies within the projection of the water receiving trough 20 onto the horizontal plane. This can be either a portion of the projection of the water receiving tray onto the horizontal plane lies within the projection of the water receiving trough 20 onto the horizontal plane, or the entire projection of the water receiving tray onto the horizontal plane lies within the projection of the water receiving trough 20 onto the horizontal plane.

[0060] When the heat exchange air supply unit generates condensate during cooling, the condensate can drip into the drip tray. At this time, the temperature of the drip tray containing condensate is low, and water vapor in the air will also condense when it encounters the low-temperature drip tray, causing condensate to form at the bottom of the drip tray. At least part of the projection of the drip tray onto the horizontal plane is located within the projection of the drip trough 20 onto the horizontal plane. When the condensate in the drip tray drips, it can drip directly into the drip trough 20. This allows the drip trough 20 to collect both the condensate flowing down from the drip tray and the condensate generated at the bottom of the drip tray when collecting condensate from the heat exchange components. Most of the condensate collected by the drip trough 20 comes from the condensate flowing down from the drip tray.

[0061] refer to Figures 1-2According to some embodiments of the present invention, the water receiving top cover 10 includes a top cover body 11 and a water-blocking flange 12. The water-blocking flange 12 is connected to the upper surface of the top cover body 11 and is arranged around the top cover body 11. The top cover body 11 and the water-blocking flange 12 together define the water receiving groove 20.

[0062] By setting the water-retaining flange 12, a water-receiving groove 20 can be defined at the water-receiving top cover 10, so that condensate dripping into the water-receiving groove 20 can be collected. If the water-retaining flange 12 is not set, the condensate dripping onto the water-receiving top cover 10 will easily flow to the outside of the water-receiving top cover 10. The water-retaining flange 12 can also play a role in reinforcing the parts. By surrounding the top cover body 11 with the water-retaining flange 12, the structural strength of the water-receiving top cover 10 can be increased and it is not easy to be damaged.

[0063] According to some embodiments of this utility model, the height of the water-blocking flange 12 is 5mm to 10mm.

[0064] For example, the height of the water-blocking flange 12 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. If the height of the water-blocking flange 12 is too small, the capacity of the water receiving tray 20 will be too small, resulting in poor water storage capacity and insufficient condensate storage, causing condensate overflow. If the height of the water-blocking flange 12 is too large, it will occupy too much space inside the air conditioner. By setting the water-blocking flange 12 to an appropriate height, the water receiving tray 20 can accommodate a sufficient amount of condensate without affecting the internal space of the air conditioner.

[0065] According to some embodiments of this utility model, the bottom surface of the water receiving tank 20 is provided with a protrusion structure 211, which includes a plurality of spaced protrusions 211. The protrusion structure 211 serves to reduce the sound of condensate dripping. Providing a plurality of spaced protrusions 211 increases the number of positions where condensate droplets can be pierced, thereby increasing the area of ​​the protrusion structure 211 that can pierce the droplets.

[0066] For example, when condensate dripping from the bottom of the drip tray, the protrusion 211 structure 21 punctures the large water droplets, breaking them into smaller droplets, reducing the sound of the dripping water, and preventing the water droplets from splashing. The broken-down small water droplets fall into the drip trough 20 and are then drained.

[0067] According to some embodiments of the present invention, the cross-sectional area of ​​the protrusion 211 decreases in the direction from bottom to top.

[0068] By setting the protrusion 211 to reduce the cross-sectional area from bottom to top, the cross-sectional area of ​​the top of the protrusion 211 is smaller, which is beneficial to puncture large water droplets. It is also beneficial to disperse the water droplets of condensate punctured by the protrusion 211 structure 21 and slide them along the side wall into the water receiving tank 20, preventing water droplets from splashing again during the decomposition process.

[0069] According to some embodiments of the present invention, the height of the protrusion 211 is 1mm to 5mm.

[0070] For example, the height of the protrusion 211 can be 1mm, 2mm, 3mm, 4mm, 5mm, etc. If the height of the protrusion 211 is too high, after piercing a large water droplet, the falling small water droplets will still produce a loud sound and are prone to splashing; if the height of the protrusion 211 is too low, it will not be effective in piercing large water droplets. By setting the protrusion 211 to an appropriate height, the sound produced when water droplets fall can be reduced while piercing large water droplets.

[0071] refer to Figure 1 According to some embodiments of this utility model, the cross-section of the protrusion 211 is circular, and the diameter of the protrusion 211 is 1mm to 3mm. The circular cross-section of the protrusion 211 facilitates the sliding of water droplets pierced by the protrusion 211 structure 21 along the side wall into the water receiving tank 20, preventing the water droplets from splashing again during the decomposition process.

[0072] For example, the diameter of the protrusion 211 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. If the diameter of the protrusion 211 is too large, large water droplets will drip directly onto the circular surface when they fall onto the protrusion 211, failing to pierce the large water droplets; if the diameter of the protrusion 211 is too small, the water droplets will pass directly through the protrusion 211, also failing to pierce the large water droplets. By setting an appropriate diameter for the protrusion 211, it is possible to effectively pierce condensate water droplets and reduce the sound of condensate water dripping.

[0073] According to some embodiments of the present invention, the bottom surface of the water receiving tank 20 is provided with a water-blocking rib 22, which surrounds the outer periphery of the protrusion 211 structure 21, and a water-draining notch 23 is formed on the water-blocking rib 22.

[0074] Among them, the water-blocking rib 22 serves to block the splashing of condensate; the water-blocking rib 22 surrounds the outer periphery of the protrusion 211 structure 21, and can block the splashing of condensate from multiple angles; the water-draining notch 23 serves to guide the condensate out, and discharges the dripping and collected condensate to the outside of the water-blocking rib 22.

[0075] For example, when the heat exchange air supply unit generates condensate and drips onto the protrusion 211 structure 21 on the bottom surface of the water receiving tank 20, the protrusion 211 structure 21 punctures the large water droplets and breaks them into small water droplets. The broken-down small water droplets fall into the water receiving tank 20, and some of the small water droplets that splash outward are blocked by the water baffle 22 and flow along the inner wall of the water baffle 22 into the water receiving tank 20.

[0076] refer to Figure 1 According to some embodiments of the present invention, a water-drawing notch 23 is provided at the lowest position of the water-blocking rib 22 in the circumferential direction.

[0077] For example, when condensate is generated by the heat exchange air supply unit and drips onto the protrusion 211 structure 21 on the bottom surface of the water receiving tank 20, the protrusion 211 structure 21 punctures the large water droplets, breaking them into smaller droplets. These smaller droplets fall into the water receiving tank 20, while some of the small droplets that splash outward are blocked by the baffle rib 22 and flow along the inner wall of the baffle rib 22 into the water receiving tank 20. The condensate collected by the small droplets flows through the water inlet 23 to the bottom of the water receiving tank 20 for discharge. The water inlet 23 guides the condensate outward, discharging the dripping and collected condensate to the outside of the baffle rib 22 to prevent condensate from accumulating inside the baffle rib 22. The baffle rib 22 is positioned at the lowest point to facilitate the discharge of the small droplets of condensate from the protrusion 211 structure 21, preventing condensate from accumulating inside the baffle rib 22.

[0078] refer to Figures 1-2 According to some embodiments of the present invention, the heat exchange air supply unit includes a water receiving tray located on the bottom surface, a water receiving top cover 10 located below the water receiving tray, at least a portion of the projection of the water receiving tray on the horizontal plane is located within the projection of the water receiving trough 20 on the horizontal plane, and at least a portion of the protrusion 211 structure 21 is located directly below the overflow hole on the water receiving tray.

[0079] The heat exchange air supply unit includes a heat exchange air supply component and a water receiving tray. The water receiving tray can be located below the heat exchange air supply component to facilitate the collection of condensate generated by the heat exchange air supply unit during cooling. The water receiving tray has an overflow hole. When there is a lot of condensate in the water receiving tray, the condensate in the water receiving tray can be discharged along the overflow hole of the water receiving tray. At least part of the projection of the water receiving tray on the horizontal plane is located within the projection of the water receiving trough 20 on the horizontal plane, so that the water receiving trough 20 can collect the condensate generated at the bottom of the water receiving tray and can also collect the condensate flowing down along the overflow hole of the water receiving tray. At least part of the protrusion 211 structure 21 is located directly below the overflow hole on the water receiving tray, which can buffer the condensate. The protrusion 211 structure 21 punctures the larger water droplets in the condensate, decomposes them into smaller water droplets, and reduces the sound of the water droplets falling. The decomposed small water droplets fall into the water receiving trough 20 and are then discharged.

[0080] For example, when the heat exchange air supply unit generates condensate, the condensate drips into the water collection tray of the heat exchange air supply unit. The water collection tray collects the condensate and discharges it through the overflow hole. The discharged condensate falls onto the protrusion 211 structure 21 directly below the overflow hole. The protrusion 211 structure 21 punctures the large water droplets, breaking them into smaller water droplets. The smaller water droplets fall into the water collection trough 20. Some of the small water droplets that splash outward are blocked by the water baffle 22 and flow along the inner wall of the water baffle 22 into the water collection trough 20. The condensate collected by the small water droplets flows from the water inlet 23 to the bottom of the water collection trough 20 and is discharged together with the other condensate collected in the water collection trough 20.

[0081] refer to Figure 6 According to some embodiments of the present invention, a drain hole 24 is provided on the bottom wall of the water receiving tank 20, and a water storage tank 30 is provided at the bottom of the air handling unit 100. The drain hole 24 is used to drain the water in the water receiving tank 20 downward into the water storage tank 30.

[0082] The water storage tank 30 serves to store the dripping condensate. For example, when condensate is generated in the water receiving pan of the heat exchange air supply unit, the condensate drips into the water receiving trough 20 of the water receiving top cover 10 of the air handling unit 100. Under the action of gravity, the condensate is collected in the water receiving trough 20 and discharged from the drain hole 24. Subsequently, the condensate is discharged into the water storage tank 30 at the bottom of the air handling unit 100 for storage.

[0083] refer to Figures 6-9 According to some embodiments of this utility model, a guide surface 25 is formed on the bottom surface of the water receiving tank 20, and the guide surface 25 extends downward at an inclination in the direction near the drain hole 24. By forming a downwardly inclined guide surface 25 on the bottom surface of the water receiving tank 20, the condensate in the water receiving tank 20 can flow along the guide surface 25 to the drain hole 24 and be discharged under the action of gravity.

[0084] For example, in Figure 7 In the example, the guide surface 25 extends downward at an angle from front to back, and the drain hole 24 is located at the rear end of the water receiving cover 10. When condensate drips into the water receiving tank 20, the condensate flows along the guide surface 25 from front to back to the rear end of the water receiving tank 20 and is discharged from the drain hole 24 at the rear end of the water receiving cover 10.

[0085] According to some embodiments of the present invention, the drain hole 24 is located near the outer edge of the water receiving top cover 10.

[0086] For example, in Figure 7 In the example, the drain hole 24 is located near the outer edge of the rear end of the water receiving top cover 10. By placing the drain hole 24 on the outer edge of the water receiving top cover 10, it is convenient for condensate to flow through the guide surface 25 and then be discharged, thus optimizing the spatial arrangement of the water receiving top cover 10.

[0087] For example, an overflow outlet 26 can be provided above the drain hole 24, and the overflow outlet 26 can be a notch in the water-blocking flange 12. When the drain hole 24 is blocked, the condensate collected from the bottom of the water receiving tank 20 can be discharged through the overflow outlet 26 to prevent condensate from accumulating in the water receiving top cover 10.

[0088] refer to Figures 1-5 According to some embodiments of the present invention, the air handling unit 100 includes a second fan 42 assembly 40, which includes a fan casing 41 and a second fan 42. The fan casing 41 has a fan duct 43. The impeller of the second fan 42 is housed within the fan duct 43. A water storage tank 30 is located below the fan duct 43. A connecting opening 44 is formed on the bottom wall of the fan duct 43, located directly above the water storage tank 30 and connecting the water storage tank 30 and the fan duct 43. A water-receiving top cover 10 is provided on the upper side of the fan casing 41. The fan casing 41 has an air inlet 47 and an air outlet 48. The air inlet 47 is connected to the air intake structure, and the air outlet 48 is connected to the air outlet structure. When the second fan 42 assembly 40 is working, the second fan 42 drives air to enter the duct casing from the air inlet 47. After being processed by the air handling unit 100, the air flows out from the air outlet 48. The impeller can be a centrifugal impeller, and the airflow entering the duct casing through the air inlet 47 can include fresh air introduced from the outside or indoor air.

[0089] For example, the air intake structure includes a first air inlet, a second air inlet, and a third air inlet; the air outlet structure includes a first air outlet and a second air outlet; the first air inlet, the second air inlet, the first air outlet, and the second air outlet are all connected to the indoor environment; the third air inlet is connected to the outdoor environment; the airflow inlet 47 includes a first airflow inlet 47147 and a second airflow inlet 47247; the first airflow inlet 47147 is connected to the second air inlet; the second airflow inlet 47247 is connected to the third air inlet; and the airflow outlet 48 is connected to the second air outlet.

[0090] The heat exchange air supply unit is used to exchange heat with the airflow entering the casing from the first air inlet and then discharge it to the room from the first air outlet. The air handling unit 100 is used to process the airflow entering the fan volute 41 from the airflow inlet 47 and then discharge it to the room from the airflow outlet 48 and the second air outlet.

[0091] The fan duct 43 serves to transfer air. The connecting port 44 is located directly above the water storage tank 30, connecting the fan duct 43 to the water storage tank 30. This allows water vapor from the evaporating water in the water storage tank 30 to enter the fan duct 43. When the fan is operating, air flows through the fan duct 43. The water in the water storage tank 30 below the fan duct 43 evaporates faster in this airflow environment, and the water vapor enters the air within the fan duct 43, increasing the humidity of the air.

[0092] refer to Figure 5 According to some embodiments of the present invention, the water storage tank 30 is located on the upstream side of the wind turbine.

[0093] As the air passes through the impeller, its flow rate slows down. The air upstream of the impeller, without obstruction, has a higher wind speed than the air downstream. By placing the water storage tank 30 upstream of the impeller, the evaporation rate of water within the tank is increased, facilitating the reuse of condensate and improving the tank's humidification effect. For example, when the impeller is operating, as condensate drips down through the drain hole 24, it is blown into the fan duct 43 by the flowing air, increasing the humidity of the air discharged from the impeller. When the impeller is off, the condensate drips directly into the water storage tank 30 through the drain hole 24.

[0094] refer to Figures 5-6 According to some embodiments of the present invention, the top of the fan volute 41 is provided with a diversion groove 45, the drain hole 24 is located above the diversion groove 45, the bottom wall of the diversion groove 45 is formed with a drain hole 46, the drain hole 46 connects the diversion groove 45 and the fan duct 43, and the projection of the drain hole 46 on the horizontal plane is located within the projection of the horizontal plane of the connecting port 44.

[0095] The drainage channel 45 is used to guide condensate to the drain hole 46 and discharge it from the drain hole 46. The drain hole 46 connects the drainage channel 45 and the fan duct 43, so that the condensate in the water receiving tank 20 can enter the fan duct 43 through the drain hole 46. The projection of the drain hole 46 on the horizontal plane is located within the projection of the connecting port 44 on the horizontal plane, and the connecting port 44 is located directly above the water storage tank 30, so that the condensate discharged from the drain hole 46 falls into the water storage tank 30.

[0096] For example, when the water collection tray of the heat exchange air supply unit produces a lot of condensate, the condensate drips into the water collection top cover 10 of the air handling unit 100. Under the action of gravity, it is collected in the water collection trough 20 and discharged from the drain hole 24, dripping into the diversion trough 45. Then, it is drained from the drain hole 46 through the diversion trough 45, so that the condensate falls into the water storage tank 30.

[0097] According to some embodiments of the present invention, an overflow port 26 is formed on the side wall of the water receiving top cover 10, and the overflow port 26 is higher than the drain hole 24 and located above the diversion groove.

[0098] For example, the overflow outlet 26 can be located above the drain hole 24, or the overflow outlet 26 can be a notch in the water-blocking flange 12. When the drain hole 24 is blocked, the condensate collected from the bottom of the water receiving tank 20 can be discharged through the overflow outlet 26, preventing the condensate from accumulating in the water receiving top cover 10.

[0099] According to some embodiments of the present invention, the air handling unit 100 includes a wet membrane and a water tank 50. The wet membrane is disposed in the fan duct 43 and located directly above the water storage tank 30. The water tank 50 is used to supply water to the wet membrane.

[0100] The wet membrane is positioned directly above the water storage tank 30 in the fan duct 43. Condensate can drip into the wet membrane through the drain hole 24 to replenish its moisture. Excess moisture in the wet membrane can also flow into the water storage tank 30 under gravity. When the moisture in the wet membrane is insufficient, the water storage tank 30 can supply water to the wet membrane, and the water tank 50 can also supply water to the wet membrane.

[0101] For example, when the heat exchange air supply unit's water tray produces a lot of condensate, the condensate drips into the water collection top cover 10 of the air handling unit 100, collects through the water collection trough 20, and is discharged from the drain hole 24 into the drainage trough 45. Then, it is drained from the drain hole 46 through the drainage trough 45. At this time, the condensate drips into the wet film and wets the wet film. The evaporation of water on the wet film material increases the humidity of the air passing through the fan duct 43. When the heat exchange air supply unit does not produce condensate or produces less condensate, the water tank 50 can supply water to the wet film to wet it. The water molecules absorb heat from the air and evaporate, thereby humidifying the air flowing through the fan duct 43.

[0102] refer to Figure 1 According to some embodiments of the present invention, the water inlet cover 10 and the fan volute 41 are detachably connected or integrally formed.

[0103] For example, the water inlet cover 10 and the fan casing 41 can be detachably connected, or they can be integrally formed. When the water inlet cover 10 and the fan casing 41 are detachably connected, it facilitates the maintenance of the fan casing 41, and the water inlet cover 10 can be disassembled. When the water inlet cover 10 and the fan casing 41 are integrally formed, it reduces the detailed processing and splicing of air conditioner components, thereby reducing costs.

[0104] Next, we will refer to Figures 1-9 The present invention describes an air conditioner according to some embodiments.

[0105] In this embodiment, the air conditioner includes a casing, a heat exchange and air supply unit, and an air handling unit 100.

[0106] The casing has an air inlet structure and an air outlet structure. A heat exchange and air supply unit is located inside the casing. An air handling unit 100 is located inside the casing and below the heat exchange and air supply unit. The top of the air handling unit 100 has a water-collecting top cover 10, on which a water-collecting groove 20 is formed. The water-collecting top cover 10 includes a top cover body 11 and a water-blocking flange 12. The water-blocking flange 12 is connected to the upper surface of the top cover body 11 and surrounds the top cover body 11. The top cover body 11 and the water-blocking flange 12 together define the water-collecting groove 20. The bottom surface of the water-collecting groove 20 has a protrusion structure 211, which includes multiple spaced protrusions 211. The cross-sectional area of ​​the protrusions 211 decreases from bottom to top. The bottom surface of the water-collecting groove 20 has a water-blocking rib 22, which surrounds the outer periphery of the protrusion structure 211. A water-draining notch 23 is formed on the water-blocking rib 22. The bottom wall of the water receiving tank 20 is provided with a drain hole 24, and the bottom of the air handling unit 100 is provided with a water storage tank 30. The drain hole 24 is close to the outer edge of the water receiving top cover 10 and is used to drain the water in the water receiving tank 20 downward into the water storage tank 30. The bottom surface of the water receiving tank 20 is formed with a guide surface 25, which extends downward at an angle in the direction close to the drain hole 24.

[0107] The heat exchange air supply unit includes a water receiving tray located on the bottom surface, a water receiving top cover 10 located below the water receiving tray, at least a portion of the projection of the water receiving tray onto the horizontal plane is located within the projection of the water receiving trough 20 onto the horizontal plane, and at least a portion of the bottom surface of the water receiving trough 20 has a protrusion 211 structure 21 located directly below the overflow hole on the water receiving tray.

[0108] The air handling unit 100 includes a second fan 42 assembly 40, which includes a fan casing 41 and a second fan 42. The fan casing 41 has a fan duct 43. The impeller of the second fan 42 is housed in the fan duct 43. A water storage tank 30 is located below the fan duct 43. A connecting port 44 is formed on the bottom wall of the fan duct 43. The connecting port 44 is located directly above the water storage tank 30 and connects the water storage tank 30 and the fan duct 43. A water receiving top cover 10 is provided on the upper side of the fan casing 41. The fan casing 41 has an air inlet 47 and an air outlet 48. The air inlet 47 is connected to the air intake structure, and the air outlet 48 is connected to the air outlet structure. The water storage tank 30 is located upstream of the impeller. A diversion channel 45 is provided on the top of the fan casing 41, and a drain hole 24 is located above the diversion channel 45. A drain hole 46 is formed on the bottom wall of the diversion channel 45, connecting the diversion channel 45 to the fan duct 43. The projection of the drain hole 46 on the horizontal plane lies within the projection of the connecting opening 44 on the horizontal plane. The air handling unit 100 includes a wet film and a water tank 50. The wet film is located inside the fan duct 43 and directly above the water storage tank 30. The water tank 50 supplies water to the wet film.

[0109] When the heat exchange air unit is working, the condensate generated in the heat exchange air unit drips into the water collection tray at the bottom of the heat exchange air unit. The condensate generated when the air comes into contact with the cooler bottom of the water collection tray drips into the water collection trough 20 of the water collection top cover 10 of the air handling unit 100. The condensate in the water collection tray is also discharged through the overflow hole to the protrusion 211 structure 21 in the water collection trough 20. When the condensate drips, the water-retaining flange 12 of the water collection top cover 10 and the water-retaining rib 22 on the bottom surface of the water collection trough 20 prevent the condensate from splashing, so that the condensate flows along the guide surface 25 to the drain hole 24 on the outer edge of the water collection top cover 10. The condensate flowing out of the drain hole 24 falls into the diversion trough 45, and then is discharged from the drain hole 46 on the bottom wall of the diversion trough 45. The condensate flowing out of the drain hole 46 flows into the wet film, and the evaporation of water on the wet film material increases the humidity of the air passing through the fan duct 43. The connecting port 44 connects the water storage tank 30 to the fan duct 43, enabling the water storage tank 30 to supply water to the wet membrane. When there is too much water in the wet membrane, the water can flow into the water storage tank 30 below the wet membrane for storage. When there is too little condensate, resulting in too little water in the wet membrane, the water tank 50 can supply water to the wet membrane to keep the water level in the wet membrane sufficient.
