Furthermore, reference numerals and / or letters may be repeated in different examples.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0033] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0034] Hereinafter, with reference to the accompanying drawings, an air handling component 100 according to a first aspect embodiment of the present invention will be described. The air handling component 100 of this application can be applied to devices such as air conditioners 200, air purifiers, or humidifiers.

[0035] It is understood that the type of air conditioner 200 in this application embodiment is not limited. It can be a vehicle air conditioner, an integrated air conditioner, or a split air conditioner. An integrated air conditioner can include a window air conditioner or a portable air conditioner, and a split air conditioner can include a wall-mounted air conditioner or a floor-standing air conditioner.

[0036] The type of purifier in this application embodiment is not limited. It can be a household purifier, a commercial purifier, or a portable purifier. Household purifiers can include desktop purifiers or floor purifiers, etc. Commercial purifiers can include industrial-grade purifiers or large building purifiers, etc. Portable purifiers can include vehicle purifiers or small personal purifiers, etc.

[0037] The type of humidifier in this application is not limited; it can be a household humidifier, a commercial humidifier, or a portable humidifier. Household humidifiers may include ultrasonic humidifiers or evaporative humidifiers, etc.; commercial humidifiers may include industrial-grade humidifiers or humidifiers used in large venues, etc.; portable humidifiers may include small portable humidifiers or vehicle humidifiers, etc.

[0038] Please refer to Figures 1-5 The air handling unit 100 includes: a housing 1, a handling module 2, and a fan assembly 3. An air duct 1a is formed inside the housing 1. The housing 1 also defines a water storage tank 11. The water storage tank 11 is located below the air duct 1a and has an open top. The handling module 2 includes a humidifier 21. The humidifier 21 is located inside the air duct 1a and above the water storage tank 11. The fan assembly 3 is connected to the air duct 1a and is located downstream of the handling module 2.

[0039] It is understood that "downstream" does not refer to spatial orientation, but rather to a relative position along the airflow direction. That is, along the airflow direction, the position reached by the airflow first is upstream, and the position reached by the airflow later is downstream. In the embodiments of this application, by setting the fan assembly 3 to be connected to the air duct 1a and located downstream of the processing module 2, when the fan assembly 3 is working, it can induce air to enter the air duct 1a, be processed by the processing module 2, and the processed air can be sent away via the fan assembly 3.

[0040] The form and humidification method of the humidifying element 21 are not limited. For example, the humidifying element 21 can be a wet film, which can obtain water by spraying water from above or absorbing water from below, and then humidify the air flowing through the wet film. Alternatively, it can be a water spraying element, a water spraying element, or a water jetting element, etc., to create a water curtain or water screen above the water storage tank 11 to humidify the air flowing through. In the embodiments of this application, by setting a water storage tank 11 below the humidifying element 21, the water storage tank 11 can serve to collect the falling water and recover the water falling at the humidifying element 21. When the humidifying element 21 is a wet film and the wet film adopts a downward water absorption method, the lower end of the wet film can also be inserted into the water storage tank 11 to absorb water.

[0041] Please refer to Figure 1 , Figure 2 and Figure 5 The air handling unit 100 also includes a liquid level control structure, which is located in the housing and is used to control the highest liquid level in the water storage tank 11.

[0042] As an example, the level control structure may include a level detection component, which may be one of a float-type level controller, a float-type level switch, a capacitive level sensor, an ultrasonic level sensor, a pressure level sensor, or an electrode-type level controller. When the level detection component detects that the water level in the water tank 11 has reached the maximum level, the level control structure cuts off the device (such as a water tank or other component) that adds water to the water tank 11. When the level detection component detects that the water level in the water tank 11 has not yet reached the maximum level, the level control structure may maintain the connection between the water adding device and the water tank 11 until the water level in the water tank 11 reaches the maximum level.

[0043] As an example, the liquid level detection structure includes a water tank assembly 4 and a water pump 23. The water tank assembly 4 is used to add water to the water storage tank 11, and the water pump 23 is used to transport the water in the water storage tank 11 to the humidifier 21. The water tank assembly 4 is configured to add water to the water storage tank 11 when the water level in the water storage tank 11 is lower than the maximum liquid level, and to stop adding water when the water level in the water storage tank 11 reaches the maximum liquid level.

[0044] Understandably, the staff can determine the maximum liquid level based on the actual operation of the air handling unit 100 so that there is enough water in the water tank 11 to humidify the humidifier 21, while the water in the water tank 11 will not be too much and cause overflow; the maximum liquid level of the water tank 11 may refer to the critical replenishment liquid level R1 mentioned later, or the maximum liquid level of the water tank 11 may be higher than the critical replenishment liquid level R1 mentioned later.

[0045] The liquid level of the water storage tank 11 refers to the vertical height or depth of the liquid actually contained inside the water storage tank 11, excluding the foam inside the water storage tank 11. Foam is a low-density, porous material formed on the surface of the liquid due to gas mixing, surfactant action, or mechanical disturbance. Its existence does not change the actual volume of the liquid and is not within the scope of liquid level measurement.

[0046] Please refer to Figure 1 , Figure 2 and Figure 5 The air handling unit 100 also includes a water-blocking structure 5, which is disposed in the housing 1 and is located between the humidifier 21 and the highest liquid level in the vertical direction, so as to block the dripping water from the humidifier 21 and guide it to the bottom wall of the water storage tank 11.

[0047] As can be seen, by placing the water-blocking structure 5 between the humidifier 21 and the highest liquid level, the water-blocking structure 5 can receive the dripping water from the humidifier 21. At the same time, the water-blocking structure 5 can guide the dripping water to the liquid surface of the water storage tank 11. Compared with the dripping water from the humidifier 21 falling directly onto the liquid surface of the water storage tank 11, the water-blocking structure 5 in this application helps to reduce the dripping drop of the humidifier 21, so that the air handling unit 100 is less likely to produce dripping sound. When the dripping water falls from a lower height, the kinetic energy is reduced, the impact energy of the dripping water is lower, and the impact force when colliding with the liquid surface is weakened, which helps to reduce the generation of foam. This makes it less likely for the air handling unit 100 to blow out foam, reducing the possibility of the air handling unit 100 blowing water. At the same time, it is also less likely for foam to overflow in the water storage tank 11, which is less likely to affect the normal operation of other components and improves the reliability of the air handling unit 100.

[0048] As an example, the air handling unit 100 also includes a water pump 23, which is located in the water storage tank 11. The water pump 23 delivers water to the top of the humidifier 21 to humidify the humidifier 21. At the same time, the unused water in the humidifier 21 can flow back into the water storage tank 11 to achieve water resource recycling. During the water resource recycling process, there may be some impurities in the water. When the water droplets from the humidifier 21 have a strong impact force with the liquid surface in the water storage tank 11, foam may be generated in the water storage tank 11. This application provides a water-blocking structure 5 to reduce the droplet drop of the humidifier 21, thereby reducing the impact force between the droplets and the liquid surface and reducing the generation of bubbles. This makes it less likely for the air handling unit 100 to blow out bubbles, thus reducing the possibility of water blowing phenomenon in the air handling unit 100.

[0049] It is understood that, in the vertical direction, the water-blocking structure 5 can be located outside the water storage tank 11, or inside the water storage tank 11, or at the opening of the water storage tank 11. This application does not limit the specific position of the water-blocking structure 5 in the vertical direction, as long as the water-blocking structure 5 can be located between the humidifying element 21 and the highest liquid level. In addition, the water-blocking structure 5 can block part of the dripping water from the humidifying element 21, or block all of the dripping water from the humidifying element 21.

[0050] Please refer to Figures 7-10 In some embodiments, the water-blocking structure 5 includes at least one water-blocking plate 51, the upper surface of which is arranged horizontally or inclined, and the water-blocking plate 51 has a drainage portion 511 located at the lowest position of the water-blocking plate 51 to guide dripping water to the bottom wall of the water storage tank 11.

[0051] As can be seen, by placing the drain section 511 at the lowest position of the baffle plate 51, the dripping water received by the upper surface of the baffle plate 51 can naturally converge to the drain section 511, so as to better guide the dripping water to the water storage tank 11.

[0052] As an example, when the upper surface of the baffle 51 is horizontally arranged, the upper surface of the baffle 51 can be partially recessed to form a drainage section 511, so that the drainage section 511 can be located at the lowest position of the baffle 51; when the upper surface of the baffle 51 is inclined, the upper surface of the baffle 51 can be inclined downward toward the location of the drainage section 511, so that the drainage section 511 can be located at the lowest position of the baffle 51. Therefore, the upper surface of the baffle 51 can be not only flush but also inclined, making the design of the baffle 51 more flexible, allowing operators to choose according to actual usage.

[0053] The water-blocking structure 5 may include one or more water-blocking plates 51. When there is one water-blocking plate 51, the upper surface of the water-blocking plate 51 may be arranged horizontally or inclined. When there are multiple water-blocking plates 51, the upper surfaces of the multiple water-blocking plates 51 may be arranged horizontally, or the upper surfaces of the multiple water-blocking plates 51 may be arranged inclined, or the upper surfaces of some water-blocking plates 51 may be arranged horizontally and the upper surfaces of other water-blocking plates 51 may be arranged inclined.

[0054] As an example, when the water-blocking structure 5 includes multiple water-blocking plates 51, the multiple water-blocking plates 51 can be arranged sequentially in the vertical direction. The uppermost water-blocking plate 51 receives the dripping water from the humidifying component 21 and can guide the dripping water to the adjacent water-blocking plate 51. The aforementioned water-blocking plate 51 then guides the dripping water to the adjacent water-blocking plate 51 until the lowermost water-blocking plate 51 guides the dripping water to the bottom wall of the water storage tank 11. This allows the dripping water to be indirectly guided into the water storage tank 11 through multiple water-blocking components, which helps to further reduce the dripping drop of the humidifying component 21, reduce the generation of bubbles, and make it less likely for the air handling component 100 to blow out bubbles, thus reducing the possibility of the air handling component 100 blowing water.

[0055] In some embodiments, the air handling component 100 is configured to satisfy at least one of the following structures A1 to A6: Please refer to Figures 7-10 In structure A1, the drainage part 511 is located on the outer periphery of the baffle plate 51. For example, the drainage part 511 is located on the width side or the length side of the baffle plate 51, so that the dripping water from the humidifier 21 is less likely to drip directly onto the water storage tank 11 through the drainage part 511 without being blocked by the baffle plate 51. This helps to reduce the size requirements of the baffle plate 51, so there will be no great restrictions on the setting position of the water blocking structure 5. For example, the water blocking structure 5 can be located outside the water storage tank 11, or inside the water storage tank 11, or at the opening of the water storage tank 11, so that the setting of the water blocking structure 5 is more flexible. On the horizontal plane, the orthographic projection of the drainage part 511 is located within the orthographic projection outer contour of the bottom wall of the water storage tank 11, so that the drainage part 511 can smoothly guide the dripping water to the water storage tank 11.

[0056] Please refer to Figure 9 and Figure 12 In structure A2, the baffle plate 51 extends into a long strip along the length of the humidifying component 21, and the width of the baffle plate 51 (e.g.) Figure 9 The humidification thickness of the humidifier (L1) is greater than or equal to that of the humidifier 21 (e.g., L1). Figure 12 The width of the baffle plate 51 is such that at least one end of the baffle plate 51 is flush with or extends beyond the humidifier 21 in the corresponding thickness direction. Therefore, the baffle plate 51 can more comprehensively receive the dripping water from the humidifier 21, preventing the dripping water from bypassing the baffle plate 51 and dripping directly into the water storage tank 11 through the drain section 511, thus improving the reliability of the water-blocking structure 5. Of course, the width of the baffle plate 51 can also be appropriately smaller than the humidification thickness of the humidifier 21.

[0057] As an example, the width of the baffle plate 51 extends beyond the thickness of the humidifier 21 at both ends, or the width of the baffle plate 51 is flush with the corresponding thickness of the humidifier 21 at both ends, or the width of the baffle plate 51 is flush with the thickness of the humidifier 21 at one end, and the other end of the width of the baffle plate 51 extends beyond the thickness of the humidifier 21 at the other end.

[0058] It is understandable that when the humidifying element 21 is a wet film, the width of the baffle plate 51 is greater than or equal to the thickness of the wet film; when the humidifying element 21 is a water curtain or water screen, the width of the baffle plate 51 is greater than or equal to the thickness of the wet film; when the humidifying element 21 is other structures, the width of the baffle plate 51 is greater than or equal to the thickness of the humidification area formed by the other structures.

[0059] Please refer to Figures 7-10 In structure A3, the drainage section 511 is located at the edge of the water baffle 51 away from the fan assembly 3, so that the drainage section 511 and the fan assembly 3 can be further apart. When the drainage section 511 guides the dripping water to the bottom of the water storage tank 11, the arrangement of the drainage section 511 helps to reduce the possibility of the dripping water being blown out directly by the fan assembly 3, so as to reduce the possibility of water blowing in the air handling unit 100 and improve the reliability of the air handling unit 100.

[0060] Please refer to Figures 7-10 In structure A4, the upper surface of the baffle plate 51 adjacent to the humidifier 21 is provided with a plurality of spaced protrusions 52. When water dripping from the humidifier 21 falls onto the upper surface of the baffle plate 51, the spaced protrusions 52 can disperse the water, making it less likely to produce dripping noise and improving the reliability of the baffle structure 5. For example, the protrusions 52 are arranged in multiple rows and columns on the upper surface of the baffle plate 51 to further reduce the possibility of dripping noise.

[0061] As an example, when the water-blocking structure 5 includes a water-blocking plate 51, the upper surface of the water-blocking plate 51 is provided with a plurality of spaced protrusions 52; when the water-blocking structure 5 includes a plurality of water-blocking plates 51, the plurality of water-blocking plates 51 are arranged sequentially in the vertical direction, the uppermost water-blocking plate 51 is provided with a plurality of spaced protrusions 52 on its upper surface, and the upper surfaces of the other water-blocking plates 51 may or may not be provided with protrusions 52, and this application does not impose any restrictions on this.

[0062] Please refer to Figures 7-10In structure A5, the outer periphery of the baffle plate 51 is provided with an upwardly extending baffle edge 53. The baffle edge 53 is arranged to avoid the drainage part 511, so that a drainage gap 531 is formed at the drainage part 511. The baffle edge 53 can prevent the dripping water on the upper surface of the baffle plate 51 from being guided to the water storage tank 11 through the area where the baffle edge 53 is located. The dripping water on the upper surface of the baffle plate 51 is more likely to be guided to the water storage tank 11 through the drainage gap 531, so that the flow direction of the dripping water on the baffle plate 51 is clearer.

[0063] Please refer to Figures 7-10 In structure A6, the drainage section 511 is located on the outer periphery of the baffle plate 51. The baffle plate 51 has a downwardly extending water guide edge 54 at the drainage section 511 so that the dripping water can flow along the water guide edge 54 to the liquid surface of the water storage tank 11. This further reduces the drip drop of the dripping water on the upper surface of the baffle plate 51, thereby reducing the impact force between the dripping water and the liquid surface. This helps to reduce the generation of bubbles, making it less likely for the air handling unit 100 to blow out bubbles, and reducing the possibility of the air handling unit 100 blowing water.

[0064] In some embodiments, the drainage section 511 is located on the outer periphery of the baffle plate 51. The width of the baffle plate 51 is greater than or equal to the humidification thickness of the humidifier 21, and at least one end of the width of the baffle plate 51 is flush with or extends beyond the humidifier 21 at one end in the corresponding thickness direction. This is so that on the horizontal plane, the orthographic projection of the drainage section 511 is located outside the orthographic projection outline of the humidifier 21, so that the dripping water from the humidifier 21 is less likely to drip directly into the water storage tank 11 through the drainage section 511 without being blocked by the baffle plate 51, thereby improving the reliability of the water-blocking structure 5.

[0065] Please refer to Figures 7-10 In some embodiments, the baffle plate 51 is provided with a plurality of protrusions 52, and the outer periphery of the baffle plate 51 is provided with a baffle edge 53, the height of the protrusions 52 (e.g. Figure 9 L3 in the middle) is lower than the height of the water-retaining edge 53 (e.g.) Figure 9 When water droplets come into contact with the protrusion 52 (L4 in the middle), the concentrated water flow can be dispersed into multiple fine streams, avoiding the dripping sound caused by single-point impact. Even if some water droplets fly up due to inertia after contacting the protrusion 52, the height difference of the water-blocking edge 53 can form a physical barrier, limiting the splash range to inside the water-blocking plate 51, so that the fan assembly 3 is not prone to water blowing phenomenon, and other structures of the air handling component 100 are not easily affected.

[0066] Please refer to Figures 7-10In some embodiments, the outer periphery of the baffle plate 51 is provided with a water-blocking edge 53. The baffle plate 51 extends into a long strip along the length direction of the humidifying member 21. The drainage part 511 is located at the width end edge of the baffle plate 51. The water-blocking edge 53 includes a first water-blocking part 532, a second water-blocking part 533, and a third water-blocking part 534. The first water-blocking part 532 and the second water-blocking part 533 are respectively located at the two ends of the length of the baffle plate 51. The third water-blocking part 534 connects the first water-blocking part 532 and the second water-blocking part 533. The third water-blocking part 534 is located at the width end of the baffle plate 51 away from the drainage part 511. That is, the end of the baffle plate 51 where the drainage part 511 is provided does not have a water-blocking part, so that the dripping water on the upper surface of the baffle plate 51 can be guided to the water storage tank 11 through the drainage part 511. At the same time, the structure of the baffle plate 51 is relatively simple and easy to process and manufacture.

[0067] As an example, the drainage section 511 is located at the edge of the water baffle 51 away from the fan assembly 3. Combined with the above-mentioned arrangement of multiple water baffles, the dripping water on the upper surface of the water baffle 51 is more likely to be guided from the edge away from the fan assembly 3 to the water storage tank 11, so as to reduce the risk of water blowing from the fan assembly 3.

[0068] Please refer to Figure 5 In some embodiments, the water-blocking structure 5 is located at or below the opening of the water storage tank 11, so that the arrangement of the water-blocking structure 5 is more flexible. Of course, in other embodiments of this application, the water-blocking structure 5 may also be located outside the opening of the water storage tank 11.

[0069] The water-blocking structure 5 has a drainage section 511 spaced apart from the side wall of the water storage tank 11 to guide dripping water to the bottom wall of the water storage tank 11. For example, one side wall of the water-blocking structure 5 is spaced apart from the side wall of the water storage tank 11 to form the drainage section 511, or the water-blocking structure 5 has a through hole that passes through it, which is spaced apart from the side wall of the water storage tank 11 and is configured as the drainage section 511.

[0070] Please refer to Figures 7-10 and Figure 13 In some embodiments, the air handling unit 100 further includes a flow-through structure 6 disposed in the water storage tank 11 and defining a flow-through channel 61. A water-blocking structure 5 is fixedly connected to the flow-through structure 6 and covers the upper part of the flow-through channel 61. As an example, the water-blocking structure 5 covers the upper part of the center surface of the flow-through structure 6.

[0071] It is understandable that the dripping water on the water-blocking structure 5 can flow to the water storage tank 11 through the flow passage structure 6, or the dripping water on the water-blocking structure 5 can flow to the water storage tank 11 without passing through the flow passage structure 6.

[0072] It can be seen that by setting the flow passage structure 6 in the water storage tank 11, the fluid can flow through the flow passage structure 6, which meets the water flow requirements. Compared with the scheme where the water storage tank 11 is empty and the flow passage structure 6 is not set in the water storage tank 11, the setting of the flow passage structure 6 can also play a role in blocking the fluid (such as air or water) to a certain extent, thereby reducing the noise at the water storage tank 11 and / or improving the overflow of water in the water storage tank 11 caused by airflow.

[0073] Please refer to Figure 7 and Figures 13-16 In some embodiments, the flow passage structure 6 includes a baffle 62, which is fixedly connected to the water blocking structure 5. The water storage tank 11 is elongated. The baffle 62 includes a plurality of baffles 621 spaced apart along the length of the water storage tank 11. The flow passage 61 includes a flow path 611 defined by the baffles 621 and extending from one end of the water storage tank 11 along the length of the water storage tank 11 toward the other end of the water storage tank 11.

[0074] As can be seen, since the flow path 611 extends from one end of the water storage tank 11 along its length to the other end, water can be present in the water storage tank 11 along its entire length, and the water level can be kept relatively constant throughout. Thus, when the humidifier 21 causes water to fall into the water storage tank 11, the water falling into the tank can be dispersed along its length by the flow path 611, ensuring that the water level remains relatively constant throughout the tank and preventing overflow due to excessively high local water levels. Furthermore, since the baffle 62 includes multiple baffles 621 spaced along the length of the water storage tank 11, these baffles can effectively separate the water in the tank, preventing water from overflowing due to large airflow or being sucked into the fan assembly 3. In addition, when the wet membrane needs to absorb water from the water storage tank 11, the water surface in the water storage tank 11 is generally flat along the entire length, which is conducive to the wet membrane absorbing water evenly.

[0075] Please refer to Figure 7 and Figures 13-16 In some embodiments, the plurality of baffles 621 include a first baffle 6211 and a second baffle 6212 alternately arranged along the length direction of the water storage tank 11. The first baffle 6211 and the second baffle 6212 are staggered along the width direction of the water storage tank 11, and the orthographic projections of the first baffle 6211 and the second baffle 6212 along the length direction of the water storage tank 11 have an overlapping area.

[0076] The phrase "the first baffle 6211 and the second baffle 6212 are staggered along the width of the water storage tank 11" means that in the orthographic projection of the flow structure 6 along the length of the water storage tank 11, the center of the first baffle 6211 and the center of the second baffle 6212 are a certain distance apart along the width of the water storage tank 11.

[0077] In this way, the first baffle 6211 and the second baffle 6212 are arranged in an alternating manner. The two sides of the water storage tank 11 in the width direction are set as the first side and the second side, respectively. The first baffle 6211 is set closer to the first side, and the second baffle 6212 is set closer to the second side. The flow path 611 may include a transverse flow path section 6113 located between the first baffle 6211 and the second baffle 6212, a first longitudinal flow path section 6111 located near the second side of the first baffle 6211, and a second longitudinal flow path section 6112 located near the first side of the second baffle 6212. The two ends of the transverse flow path section 6113 are connected to the first longitudinal flow path section 6111 and the second longitudinal flow path section 6112, respectively, so that the flow path 611 presents a serpentine shape (or an S-shape).

[0078] Therefore, the design of the flow structure 6 is simple and easy to process. It can form a flow path 611 that extends from one end of the water storage tank 11 along its length to the other end. Moreover, the multiple baffles 621 have a more obvious effect on water separation. Not only can the water flow smoothly, but it can also effectively prevent the water surface from swaying and overflowing from the water storage tank 11 due to the large airflow.

[0079] Of course, this application is not limited to this. For example, in other embodiments of this application, each baffle 621 can be centrally located, and the baffle 621 can form a longitudinal flow path 611 segment on both sides along the width direction of the water storage tank 11. This can also form a flow path 611 extending from one end of the length direction of the water storage tank 11 to the other end of the length direction of the water storage tank 11.

[0080] Please refer to Figures 7-10 In some embodiments, the highest point of the water-blocking structure 5 is lower than the top of the baffle 621, and the distance between the highest point of the water-blocking structure 5 and the top of the baffle 621 is L, where 3mm ≤ L ≤ 4mm. It can be seen that by setting the distance between the highest point of the water-blocking structure 5 and the top of the baffle 621 within the range of 3mm to 4mm, even if there is a large amount of water on the water-blocking structure 5 or the wind force of the fan assembly 3 is strong, the baffle 621 can still effectively block the water on the water-blocking structure 5, making it less likely for the air handling unit 100 to experience water blowing, thus improving the reliability of the air handling unit 100.

[0081] Please refer to Figures 7-10In some embodiments, the water-blocking structure 5 includes a water-blocking plate 51 and a water-blocking edge 53. The drainage part 511 is located at the edge of the water-blocking plate 51, and the water-blocking edge 53 is provided on the outer periphery of the water-blocking plate 51 and extends upward. The water-blocking edge 53 is arranged to avoid the drainage part 511 so that a drainage gap 531 is formed at the drainage part 511. The top of the water-blocking edge 53 is configured to form the highest position of the water-blocking structure 5, that is, the distance between the top of the water-blocking edge 53 and the top of the baffle 621 is L, 3mm≤L≤4mm.

[0082] As can be seen, the water baffle 53 can prevent the dripping water on the upper surface of the water baffle 51 from being guided to the water storage tank 11 through the area where the water baffle 53 is located. The dripping water on the upper surface of the water baffle 51 is more likely to be guided to the water storage tank 11 through the drainage gap 531. When there is a lot of water on the water baffle 51 or the wind force of the fan assembly 3 is strong, the water on the water baffle 51 may be blown out by the fan assembly 3. At this time, the baffle 621 can also play a certain blocking effect on the water on the water baffle structure 5, so that the air handling component 100 is less likely to produce water blowing phenomenon, which is conducive to improving the reliability of the air handling component 100.

[0083] Please refer to Figures 13-16 In some embodiments, the flow passage structure 6 includes a first side plate 63 and a second side plate 64 extending along the length direction of the water storage tank 11. The first side plate 63 and the second side plate 64 are spaced apart along the width direction of the water storage tank 11. The flow passage 61 is located between the first side plate 63 and the second side plate 64. The second side plate 64 is located on the side of the first side plate 63 near the fan assembly 3. Two adjacent baffles 621 are connected to the first side plate 63 and the second side plate 64 respectively at their ends that are far apart from each other in the width direction of the water storage tank 11.

[0084] As an example, the plurality of baffles 621 include a first baffle 6211 and a second baffle 6212 alternately arranged along the length direction of the water storage tank 11, the first baffle 6211 and the second baffle 6212 being staggered along the width direction of the water storage tank 11, the orthographic projections of the first baffle 6211 and the second baffle 6212 along the length direction of the water storage tank 11 having an overlapping area, the first baffle 6211 being connected to the first side plate 63 and spaced apart from the second side plate 64, so that in the first baffle 621 A first longitudinal flow section 6111 is formed between the first side plate 63 and the second side plate 64. The second baffle 6212 is connected to the second side plate 64 and spaced apart from the first side plate 63, so as to form a second longitudinal flow section 6112 between the second baffle 6212 and the first side plate 63. A transverse flow section 6113 is formed between the first baffle 6211 and the second baffle 6212. The flow path 611 includes the first longitudinal flow section 6111, the transverse flow section 6113 and the second longitudinal flow section 6112 connected in a serpentine manner.

[0085] Thus, the first baffle 6211 is connected to the first side plate 63, and the second baffle 6212 is connected to the second side plate 64, thereby improving the overall structural strength and reliability of the flow structure 6, and forming a reliable flow path 611 without requiring the shape of the water storage tank 11.

[0086] The drainage section 511 is located at one end of the water-blocking structure 5 adjacent to the first side plate 63, that is, the drainage section 511 is located on the side of the water-blocking structure 5 away from the fan assembly 3, and the drainage section 511 is spaced apart from the first side plate 63. For example, the water-blocking structure 5 and the first side plate 63 are spaced apart to form the drainage section 511, so that the water-blocking structure 5 can guide water from the side away from the fan assembly 3 into the water storage tank 11, so as to reduce the risk of water blowing from the fan assembly 3. The water-blocking structure 5 is spaced apart from or connected to the second side plate 64. When the water-blocking structure 5 and the second side plate 64 are spaced apart, when there is a lot of water on the water-blocking structure 5, the water can also flow to the water storage tank 11 through the gap between the water-blocking structure 5 and the second side plate 64. When the water-blocking structure 5 and the second side plate 64 are connected, the water-blocking structure 5 and the flow-through structure 6 can have better structural strength, which is conducive to improving the service life of the water-blocking structure 5 and the flow-through structure 6.

[0087] Please refer to Figure 9 , Figure 10 , Figure 13 and Figure 16 In some embodiments, the flow passage structure 6 further includes a reinforcing rib 65. The reinforcing rib 65 connects to the adjacent baffle 621 and is higher than the bottom of the baffle 621, and is also connected to the bottom of the water-blocking structure 5. This effectively ensures the distance between adjacent baffles 621, thus guaranteeing the reliability of the flow path 611 and improving the overall structural reliability and stability of the flow passage structure 6 to a certain extent. It also enhances the connection strength of the water-blocking structure 5. Furthermore, the reinforcing rib 65 being higher than the bottom of the baffle 621 ensures that even when the water volume in the flow passage 61 is small, the flow within the flow passage 61 is less likely to be affected by the reinforcing rib 65.

[0088] For example, when the flow passage structure 6 includes a first side plate 63 and a second side plate 64, the reinforcing rib 65 is located between the first side plate 63 and the second side plate 64, and the reinforcing rib 65 is spaced apart from the first side plate 63 along the width direction of the water storage tank 11, and the reinforcing rib 65 is spaced apart from the second side plate 64 along the width direction of the water storage tank 11, thereby facilitating the flow of the flow path 611.

[0089] It is worth noting that in the embodiments of this application, the reinforcing rib 65 can be provided simultaneously with the first side plate 63 and the second side plate 64, which can further improve the reliability and stability of the flow structure 6. Alternatively, in other embodiments of this application, when the reinforcing rib 65 is provided, the first side plate 63 or the second side plate 64 may not be provided.

[0090] It is understood that the position of the reinforcing rib 65 is not limited. For example, the reinforcing rib 65 can be located at the center of the width direction of the water storage tank 11, thereby simplifying the structure and facilitating processing. Alternatively, multiple reinforcing ribs 65 can be spaced apart along the width direction of the water storage tank 11. Exemplarily, the reinforcing ribs 65 between each pair of adjacent baffles 621 can be connected to form a straight line that generally extends along the length direction of the water storage tank 11. Of course, this is not the only possibility. In other embodiments of this application, the reinforcing ribs 65 between adjacent baffles 621 can also be arranged to be staggered along the width direction of the water storage tank 11, etc.

[0091] In some embodiments, the flow-through structure 6 and the water-blocking structure 5 are integrated into a flow-through water-blocking component 300, which is detachably installed in the water storage tank 11. Thus, the flow-through structure 6 and the water-blocking structure 5 can be processed together, and for the existing housing 1, only the separately processed water-blocking structure 5 and flow-through structure 6 need to be installed, eliminating the need for redesign and mold opening of the housing 1, thereby reducing design costs.

[0092] For example, when the flow-through baffle 300 is installed inside the water storage tank 11, the flow-through baffle 300 can be configured to be detachably installed inside the water storage tank 11. That is, the flow-through baffle 300 is not a non-removable part integrated into the housing 1, but can be disassembled and installed as needed, so that the flow-through baffle 300 can be removed for cleaning or replacement, and the water storage tank 11 can be cleaned by removing the flow-through baffle 300, thereby improving the cleanliness of the air delivered by the air handling unit 100.

[0093] Of course, this application is not limited to this. For example, in other embodiments of this application, when the overflow baffle 300 is installed in the water storage tank 11, the overflow baffle 300 can also be fixedly installed in the water storage tank in a non-removable manner, such as by bonding, welding, riveting, etc.

[0094] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, the liquid level control structure includes a water tank assembly 4 and a water pump 23. The water tank assembly 4 is used to add water to the water storage tank 11, and the water pump 23 is used to transport the water in the water storage tank 11 to the humidifying element 21. The humidifying element 21 is a wet film. The water storage tank 11 has a critical replenishment liquid level R1. The water tank assembly 4 is configured to add water when the water level in the water storage tank 11 is lower than the critical replenishment liquid level R1, and to stop adding water when the water level in the water storage tank 11 reaches the critical replenishment liquid level R1.

[0095] As can be seen, when the water level in the water storage tank 11 is lower than the critical replenishment level R1, the water tank assembly 4 can add water to the water storage tank 11 so that there is enough water in the water storage tank 11 to humidify the humidifying element 21. At the same time, when the water level in the water storage tank 11 reaches the critical replenishment level R1, the water tank assembly 4 stops adding water to the water storage tank 11 to ensure that the water storage tank 11 has a suitable water volume, making it less likely to overflow and to some extent helping to reduce the water blowing phenomenon of the fan assembly 3. Moreover, when the water level in the water storage tank 11 is higher than the critical replenishment level R1, the water pump 23 can accelerate the water supply to the wet membrane to prevent the water level in the water storage tank 11 from becoming too high and to reduce the risk of water blowing.

[0096] The humidifier 21 is a wet film. When the wet film is humidifying, less water drips into the water storage tank 11, so that the water level in the water storage tank 11 is not too much higher than the critical replenishment level R1, thereby reducing the risk of water blowing in the air handling unit 100 and improving the reliability of the air handling unit 100.

[0097] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, the water storage tank 11 is elongated, and the housing 1 further defines a water inlet tank 12. The water inlet tank 12 is connected to one end of the length of the water storage tank 11. The water tank assembly 4 is located above the water inlet tank 12 and includes a water tank 41 and a water outlet valve 42. The water outlet valve 42 is located at the bottom of the water tank 41 and includes a valve seat 421 and a valve core. The valve core is movable relative to the valve seat 421 between an open valve state and a closed valve state. The valve seat 421 includes a surrounding portion 4211 located outside the water tank 41. The surrounding portion 4211 surrounds a receiving groove 42111 with the outlet facing downward. A protrusion 121 is formed on the bottom wall of the water inlet tank 12. The protrusion 121 extends into the receiving groove 42111 and abuts against the portion of the valve core located outside the water tank 41, so that the valve core is kept in the open valve state.

[0098] As an example, the valve seat 421 has an outlet that connects the water tank 41 and the receiving groove 42111. The outlet valve 42 is located at the bottom of the water tank 41 so that the valve core can be locked against the valve seat 421 under the action of gravity. The valve core is blocked at the outlet, and the outlet valve 42 is in the closed state. When the protrusion 121 locks against the part of the valve core located outside the water tank 41, so that the valve core and the valve seat 421 are no longer locked, the valve core opens the outlet. For example, the protrusion 121 can push the valve core to move away from the outlet along the axial direction of the outlet valve 42, so that the valve core and the valve seat 421 are no longer locked, and the outlet valve 42 is in the open state.

[0099] The height of the opening of the receiving tank 42111 corresponds to the critical replenishment level R1. The water tank 41 is connected to the water injection tank 12 through the opening of the receiving tank 42111. The water injection tank 12 is connected to the water storage tank 11, meaning that the water level of the water injection tank 12 and the water level of the water storage tank 11 can be kept consistent. When the water level of the water storage tank 11 is lower than the critical replenishment level R1, the opening of the receiving tank 42111 is above the water level of the water storage tank 11, so that air can indirectly enter the water tank 41 through the opening of the receiving tank 42111. The water tank 41 will add water to the water injection tank 12 until the water level of the water storage tank 11 reaches the height of the opening of the receiving tank 42111, or until the water in the water storage tank 11 completely submerges the opening of the receiving tank 42111. When the water level in the storage tank 11 is higher than the height of the opening of the receiving tank 42111, air cannot indirectly enter the water tank 41 through the opening of the receiving tank 42111, and the water tank 41 will not add water to the water filling tank 12.

[0100] Alternatively, the enclosure portion 4211 may have a connecting opening 42112 to connect the inner and outer sides of the receiving tank 42111, with the height of the connecting opening 42112 corresponding to the critical replenishment level R1. As an example, the enclosure portion 4211 may be a tubular structure, with the space enclosed by the enclosure portion 4211 forming the inner side of the receiving tank 42111, and the outer side of the enclosure portion 4211 forming the outer side of the receiving tank 42111.

[0101] When the water level in the storage tank 11 is below the critical replenishment level R1, part of the connecting port 42112 is above the water level in the storage tank 11, allowing air to indirectly enter the water tank 41 through the connecting port 42112. The water tank 41 will then add water to the filling tank 12 until the water level in the storage tank 11 reaches the height of the connecting port 42112, or until the water in the storage tank 11 completely submerges the connecting port 42112. When the water level in the storage tank 11 is higher than the height of the connecting port 42112, i.e., the water level in the storage tank 11 is higher than the top of the connecting port 42112, air cannot indirectly enter the water tank 41 through the connecting port 42112, and the water tank 41 will not add water to the filling tank 12.

[0102] It is understandable that the water tank 41 is connected to the water filling tank 12 through the connecting port 42112. At this time, the water level in the water filling tank 12 and the water storage tank 11 is related to the height position of the connecting port 42112, but not to the position of the opening of the receiving tank 42111. This helps to reduce the restriction on the position of the opening of the receiving tank 42111. For example, the height position of the opening of the receiving tank 42111 can be higher than, lower than or equal to the height position of the connecting port 42112.

[0103] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, the water pump 23 is disposed in the water storage tank 11 and is used to transport water in the water storage tank 11 to the humidifier 21. The water pump 23 has a water inlet 231 and an impeller 232. The water inlet 231 is located below the impeller 232 so that the water pump 23 can better draw water. The critical water replenishment level R1 is higher than the impeller 232 so that the impeller 232 can be submerged in water at all times, so that the water pump 23 can maintain a stable flow and pressure output, and is less likely to run dry, which helps to improve the reliability of the air handling unit 100.

[0104] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, the water storage tank 11 is elongated, with its bottom wall extending downwards towards the location of the water pump 23. The lowest region of the bottom wall of the water storage tank 11 forms a downwardly recessed water collection trough 111, with the inlet 231 lower than the opening of the water collection trough 111. In other words, the water in the water storage tank 11 tends to flow towards the water collection trough 111. Therefore, even when the water volume in the water storage tank 11 is low, the water will still accumulate in the water collection trough 111, ensuring that the water flow in the water storage tank 11 is concentrated at the inlet 231 of the water pump 23. This prevents the water pump 23 from running dry and causing damage, thereby improving the reliability of the water pump 23.

[0105] The water pump 23 is located at the end of the water storage tank 11 away from its water filling position in the length direction. For example, the housing 1 also defines a water injection tank 12, which is connected to the end of the water storage tank 11 away from the water collection tank 111. The water tank assembly 4 is located above the water injection tank 12 so that the water pump 23 and the water tank assembly 4 can make full use of the space on both sides of the housing 1 for arrangement. At the same time, the distance between the water tank assembly 4 and the water pump 23 can be increased to avoid the water pump 23 interfering with the installation and disassembly of the water tank 41.

[0106] Please refer to Figure 11 and Figure 12 In some embodiments, the processing module 2 further includes a purification element 22 located upstream of the humidifier 21. As can be seen, the purification element 22, located upstream of the humidifier 21, can filter out dust and impurities in the air, ensuring that the air entering the air handling unit 100 is cleaner and improving the humidification effect. At the same time, it can prevent humid air from contacting the purification element 22, which could affect its filtration performance or cause blockage, reducing the risk of damage to the purification element 22 due to humid air and extending its service life.

[0107] For example, the purification component 22 includes a first filter 221 and a second filter 222. Both the first filter 221 and the second filter 222 are located upstream of the humidifying component 21 and are arranged sequentially along the airflow direction. The first filter 221 and the second filter 222 can filter out dust and impurities in the air, ensuring that the air entering the humidifying component 21 is cleaner and improving the humidification effect. At the same time, it can prevent humid air from contacting the first filter 221 and the second filter 222, which could affect the filtration performance of the first filter 221 and the second filter 222 or cause blockage, reducing the risk of damage to the first filter 221 and the second filter 222 due to humid air and extending their service life.

[0108] The first filter 221 and the second filter 222 are made of different materials. Different materials allow for different filtration effects on particles of different sizes and / or for filtering different types of impurities. For example, the first filter 221 is a HEPA filter, and the second filter 222 is a manganese mesh. The HEPA filter is mainly used to filter tiny particles in the air, such as dust, pollen, bacteria, and viruses. It can effectively capture particles with a diameter of 0.1 micrometers or larger. The HEPA filter has a high filtration efficiency, filtering allergens and pathogens in the air to ensure air cleanliness. The manganese mesh is mainly used to adsorb odor substances in the air, improving air quality. The combined use of the two filters ensures air cleanliness and improves the filtration efficiency of the air handling unit 100.

[0109] An air conditioner 200 according to a second aspect of the present invention includes an air handling unit 100 according to a first aspect of the present invention.

[0110] According to the air conditioner 200 of the present utility model embodiment, the air handling component 100 is less likely to produce dripping sound and water blowing phenomenon during operation, which facilitates the improvement of the reliability of the air conditioner 200.

[0111] Please refer to Figure 17 In some embodiments, the length direction of the air conditioner 200 is vertical, and the air conditioner 200 also includes an air heat exchange component 7. The air heat exchange component 7 and the air handling component 100 are arranged vertically to better utilize the space in the length direction of the air conditioner 200, so that the space occupied by the air conditioner 200 in the horizontal direction is not large, the layout is more compact, and it is easier to realize the miniaturization design of the air conditioner 200, making it more adaptable to a variety of different installation environments. For example, as Figure 17 As shown, the air conditioner 200 is a vertical air conditioner, and the air handling unit 100 is located below the heat exchange and air supply assembly. Of course, the air handling unit 100 can also be located above the heat exchange and air supply assembly.

[0112] Please refer to Figures 7-10 According to the third aspect embodiment of the present invention, the flow-through baffle 300 is suitable for being installed in a water tank, for example, in the water storage tank 11 of the air handling component 100, or in other devices or components where water needs to pass through, where waterproofing is required, where dripping noise needs to be reduced, and where the risk of water blowing needs to be reduced. That is, the application scenarios of the flow-through structure 4 in this embodiment are not limited to the air handling component 100 described above.

[0113] Among them, the flow-through water-blocking component 300 is an integrated structural component, that is, the flow-through water-blocking component 300 is a separately processed integrated structural component. The flow-through structure 6 and the water-blocking structure 5 can be installed as a whole in the required position, and can also be set to be detached as a whole from its installation position.

[0114] The flow-through baffle 300 includes a flow-through structure 6 and a water-blocking structure 5. The flow-through structure 6 is elongated and includes a plurality of baffles 621 spaced apart along its length. The plurality of baffles 621 include a first baffle 6211 and a second baffle 6212 alternately arranged along the length of the flow-through structure 6. The first baffle 6211 and the second baffle 6212 are offset along the width of the flow-through structure 6, and the orthographic projections of the first baffle 6211 and the second baffle 6212 along the length of the flow-through structure 6 have an overlapping area, so that the baffles 621 participate in defining a flow path 611 extending from one end of the length of the flow-through structure 6 to the other end of the length. The water-blocking structure 5 covers the upper part of the flow path 611 to block the dripping water falling toward the flow path 611 and guide the dripping water to the lower part of the flow path 611. Therefore, the flow path 611 can be used to achieve flow, and multiple baffles 621 can be used to divide the water, reducing the problem of water overflowing in the flow path 611 along the width direction of the flow structure 6. At the same time, the water-blocking structure 5 can receive dripping water and guide the dripping water to the lower part of the flow path 611, reducing the dripping drop, so as to reduce the dripping sound, which helps to reduce the generation of foam and reduce the risk of water blowing.
