Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, and in particular to an air treatment component and an air conditioner. Background Technology

[0002] In some humidification devices, a wet membrane is used to humidify the air. Water permeates along the wet membrane to form a water film, and the water evaporates naturally when air flows through the wet membrane, thus achieving humidification. However, in related technologies, the wet membrane is prone to localized high moisture content, which makes the water on the wet membrane easily carried into the air duct by the wind, causing leakage. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an air handling component and an air conditioner, wherein the air handling component can improve the water leakage problem caused by excessive local moisture content in the wet film.

[0005] According to the air handling component of this utility model embodiment, by setting the water filling position of the water receiving tank to be staggered from any of the distribution holes, and the width of the water receiving tank being less than the thickness of the wet film, the water in the water receiving tank can be quickly dispersed along the length of the water receiving tank. This allows the water in the water receiving tank to flow not only from the distribution holes closer to the water filling position but also from the distribution holes farther away from the water filling position, so that the water in the water receiving tank can flow through all the distribution holes.

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.

[0030] 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. It will be understood that the air handling component 100 can be used in air conditioners, air purifiers, or humidifiers, etc.

[0031] like Figures 1-4As shown, the air handling unit 100 includes a housing 1, a handling component 2, a fan assembly 3, and a water supply assembly 4. An air duct 1a is formed within the housing 1, and the housing 1 also defines a water storage tank 1b. The water storage tank 1b is located below the air duct 1a and has an open top. The handling component 2 is located within the air duct 1a and includes a support 21 and a wet film 22. The top of the support 21 forms a water receiving trough 21a with its opening facing upwards. The bottom wall of the water receiving trough 21a has multiple distribution holes 21c that are spaced apart and pass through along the length of the water receiving trough 21a. The wet film 22 is located on the support 21 and is vertically opposite to the multiple distribution holes 21c. The wet film 22 is located above the water storage tank 1b. The fan assembly 3 is connected to the air duct 1a. The water supply assembly 4 is used to add water to the water supply position 21b of the water receiving trough 21a. The water supply position 21b is offset from any of the distribution holes 21c.

[0032] As can be seen, the water filling component 4 can add water to the water receiving tank 21a at the water filling position 21b. The water outlet of the water filling component 4 can flow from the water filling position 21b to other positions in the water receiving tank 21a. The distribution hole 21c can penetrate the bottom wall of the water receiving tank 21a. The water in the water receiving tank 21a can flow downward to the wet membrane 22 through multiple distribution holes 21c. The water storage tank 1b can receive the dripping water on the wet membrane 22 to collect the water dripping from the wet membrane 22. The water filling position 21b is staggered from any of the distribution holes 21c, so that the water flowing down from the water filling position 21b is not easily concentrated through one of the distribution holes 21c. This allows the water flowing down from the water filling position 21b to be better distributed in the water receiving tank 21a through multiple distribution holes 21c.

[0033] As an example, the housing 1 is provided with a water nozzle, which is connected to the water supply pipeline. The water outlet position of the water nozzle is set opposite to the water receiving tank 21a. The orthographic projection of the water outlet position of the water nozzle on the bottom wall of the water receiving tank 21a can be used as the water filling position 21b; or a water outlet hole is formed on the bottom wall or side wall of the water receiving tank 21a, which is connected to the water supply pipeline. The location of the water outlet hole can be used as the water filling position 21b.

[0034] like Figure 3 and Figure 4As shown, the width D of the water receiving trough 21a (which can be understood as the maximum width of the water receiving trough 21a) is smaller than the thickness T of the wet film 22, making the width of the water receiving trough 21a relatively narrow. Therefore, under the same quantity, the water flowing from the water filling position 21b into the water receiving trough 21a can be dispersed as quickly as possible along the length of the water receiving trough 21a and flow to multiple distribution holes 21c more quickly. This helps to improve the problem that the water in the water receiving trough 21a is slow due to the large width of the water receiving trough 21a, which makes it easy for water in the water receiving trough 21a to fall into the distribution holes 21c near the water filling position 21b, which can easily lead to uneven water distribution at multiple distribution holes 21c and excessively high local water content in the wet film 22. It can be understood that excessively high local water content in the wet film 22 can easily cause water on the wet film 22 to be carried into the air duct 1a by the airflow, causing water leakage.

[0035] The above-described configuration of this application, combined with the staggered arrangement of the water inlet position 21b and any distribution hole 21c, and the scheme in which the width of the water inlet 21d is greater than or equal to the thickness of the wet film 22, allows the water in the water inlet 21a to be quickly dispersed along the length of the water inlet 21a. This ensures that the water in the water inlet 21a can flow not only from the distribution hole 21c closer to the water inlet position 21b, but also from the distribution hole 21c farther from the water inlet position 21b, so that the water in the water inlet 21a can flow through all the distribution holes 21c. This improves the uniformity of the moisture content of the wet film 22, reduces leakage problems, and enhances the operational reliability of the air handling unit 100.

[0036] It is understood that in this embodiment of the application, the water filling position 21b is located along the length of the water receiving tank 21a (e.g., Figure 3 The first horizontal direction) and the width direction (e.g.) Figure 3 The position of the water filling position 21b in the second horizontal direction is not specifically limited, nor is the relative position of the water filling position 21b and the multiple distribution holes 21c limited. For example, in the length direction of the water receiving tank 21a, the water filling position 21b can be located at one end or in the middle of the length of the water receiving tank 21a; for example, in the length direction of the water receiving tank 21a, the multiple distribution holes 21c are all located on one side of the water filling position 21b, or at least one distribution hole 21c is provided on each of the opposite sides of the water filling position 21b.

[0037] In some embodiments, such as Figure 3 and Figure 9As shown, the water receiving trough 21a is divided into a first trough 21d and a second trough 21e by the water filling position 21b. The first trough 21d and the second trough 21e are connected and arranged along the length of the water receiving trough 21a. The first trough 21d and the second trough 21e are arranged sequentially along the length of the water receiving trough 21a, and are connected at the water filling position 21b. The first trough 21d and the second trough 21e each correspond to at least one distribution hole 21c. The water filling position 21b has distribution holes 21c on both sides of the water receiving trough 21a along its length. The width of at least one of the first trough 21d and the second trough 21e is within the water filling position 21b. As the length of the water tank 21a decreases in the direction away from the water inlet position 21b, the water flowing from the water inlet position 21b to at least one of the first tank section 21d and the second tank section 21e can be guided by the tank wall. Due to the reduced width of the tank, the flow space provided for the water is reduced, which can appropriately increase the water flow speed and guide the water to a position in the water tank 21a that is farther away from the water inlet position 21b more quickly. In particular, for the distribution holes 21c that are farther away from the water inlet position 21b, it is easier to ensure that the water in the water tank 21a can flow into all the distribution holes 21c in a timely manner, thereby improving the uniformity of the water content of the wet film 22.

[0038] It can be understood that the length direction of the water receiving tank 21a is the same as the length direction of the first tank 21d and the length direction of the second tank 21e, and the width direction of the water receiving tank 21a is the same as the width direction of the first tank 21d and the width direction of the second tank 21e.

[0039] In some embodiments, such as Figure 9 As shown, along the length of the water receiving tank 21a, the maximum distance L1 between the distribution hole 21c in the first tank 21d and the water filling position 21b is less than the maximum distance L2 between the distribution hole 21c in the second tank 21e and the water filling position 21b. Therefore, compared with the water flowing to the second tank 21e from the water filling position 21b to the first tank 21d, the water flowing to the second tank 21e needs to have stronger fluidity, or in other words, the water flowing to the second tank 21e needs to have a greater flow velocity. To this end, at least a portion of the width D1 of the first groove 21d remains unchanged along the length of the water receiving groove 21a, while the width D2 of the second groove 21e decreases along the length of the water receiving groove 21a in a direction away from the first groove 21d, so that the arrangement of the first groove 21d and the second groove 21e can match their required water flow capacity, making it easier for water flowing to the second groove 21e to flow further to the distribution hole 21c in the second groove 21e that is furthest from the water filling position 21b.

[0040] In some embodiments, along the length of the water receiving tank 21a, the maximum distance between the distribution hole 21c in the first tank 21d and the water filling position 21b is equal to the maximum distance between the distribution hole 21c in the second tank 21e and the water filling position 21b. The width of the first tank 21d and the width of the second tank 21e decrease respectively along the length of the water receiving tank 21a away from the water filling position 21b. Therefore, water flows from the water filling position 21b to the first tank 21d and water flows to the second tank 21e. The difference in fluidity between the two is not significant. However, the aforementioned trough width settings of the first trough 21d and the second trough 21e ensure that the water flowing to the first trough 21d and the second trough 21e flows as far away from the water filling position 21b as possible. This makes it easier for the water flowing to the first trough 21d to reach the distribution hole 21c, which is furthest from the water filling position 21b, and for the water flowing to the second trough 21e to reach the distribution hole 21c, which is furthest from the water filling position 21b, in the second trough 21e.

[0041] In this embodiment of the application, regardless of whether the distance L1 is less than L2 or the distance L1 is equal to L2, the water filling position 21b can be located in the middle of the water receiving tank 21a or offset from the middle of the water receiving tank 21a along the length direction of the water receiving tank 21a.

[0042] In some embodiments, such as Figure 3 and Figure 9 As shown, along the length of the water receiving tank 21a, the maximum distance L1 between the distribution hole 21c in the first tank 21d and the water filling position 21b is less than the maximum distance L2 between the distribution hole 21c in the second tank 21e and the water filling position 21b. The number of distribution holes 21c corresponding to the first tank 21d is less than the number of distribution holes 21c corresponding to the second tank 21e. Therefore, compared to the water flowing to the second tank 21e from the water filling position 21b, the water flowing to the first tank 21d from the water filling position 21b is less likely to flow to the second tank 21e. The water tank 41 needs to have stronger fluidity, or in other words, the water flowing to the second tank 21e needs to have a greater flow rate, and the amount of water flowing to the second tank 21e needs to be greater than the amount of water flowing to the first tank 21d. For this purpose, the bottom wall of the first tank 21d is provided with a first water-blocking structure 21f. The first water-blocking structure 21f is spaced apart from at least one of the side walls of the tank on opposite sides of the first tank wall. The side of the first water-blocking structure 21f away from the water filling position 21b is provided with at least one distribution hole 21c.

[0043] It can be seen that the first water-blocking structure 21f can block the water in the first tank 21d to a certain extent, which is beneficial to the resistance of the water flowing to the first tank 21d and can increase the amount of water flowing to the second tank 21e to a certain extent. At the same time, the first water-blocking structure 21f will not completely block the flow to the distribution hole 21c on the side of the first water-blocking structure 21f away from the water filling position 21b. Moreover, the water flowing through the first water-blocking structure 21f is accelerated due to the narrowing of the flow space, so that the water can flow to the distribution hole 21c on the side of the first water-blocking structure 21f away from the water filling position 21b more quickly.

[0044] For example, in Figure 9 In the example, along the length of the water receiving tank 21a, the maximum distance L1 between the distribution hole 21c and the water filling position 21b in the first tank 21d is less than the maximum distance L2 between the distribution hole 21c and the water filling position 21b in the second tank 21e. The number of distribution holes 21c corresponding to the first tank 21d is less than the number of distribution holes 21c corresponding to the second tank 21e. The number of distribution holes 21c corresponding to the first tank 21d is less than the number of distribution holes 21c corresponding to the second tank 21e. At least a portion of the width of the first tank 21d remains unchanged along the length of the water receiving tank 21a. The width of the second tank 21e decreases along the length of the water receiving tank 21a in a direction away from the first tank 21d. A first water-blocking structure 21f protrudes from the bottom wall of the first tank 21d.

[0045] In some embodiments, such as Figure 3 and Figure 9As shown, the first water-blocking structure 21f is constructed as a water-blocking rib. Therefore, the structure of the first water-blocking structure 21f is simple and easy to implement. The water-blocking rib extends along the width direction of the first groove 21d or extends in a direction inclined relative to the width direction of the first groove 21d. Thus, the water-blocking rib and the corresponding groove sidewall of the first groove 21d can be set perpendicularly or obliquely, making the water-blocking rib setting quite flexible. And / or, the first water-blocking structure 21f is located between the distribution hole 21c closest to the water-filling position 21b in the first groove 21d and the water-filling position 21b, to separate the water-filling position 21b from the corresponding distribution hole 21c. That is, in the length direction of the water receiving groove 21a, the first water-blocking structure 21f is located between the water-filling position 21b and all the distribution holes 21c of the first groove 21d. Therefore, from the water-filling position... Water flowing from 21b to the first tank 21d first passes through the first water-blocking structure 21f and then flows to the distribution hole 21c of the first tank 21d. The first water-blocking structure 21f can more directly block the water flowing from the self-filling position 21b to the first tank 21d, which facilitates further increasing the water flow to the second tank 21e, so that the water in the second tank 21e can flow to the farthest distribution hole 21c as much as possible, further improving the problem of excessive local water content in the wet film 22. At the same time, if the first tank 21d is provided with multiple distribution holes 21c, then the first water-blocking structure is located upstream of the multiple distribution holes 21c of the first tank 21d, so the resistance to the multiple distribution holes 21c is relatively small, and it is not easy to have too much impact on the water volume of the multiple distribution holes 21c of the first tank 21d.

[0046] It is understood that the first water-blocking structure 21f can be connected to one of the two side walls of the first groove 21d, and spaced apart from the other side wall; or, the first water-blocking structure 21f can be spaced apart from the two side walls of the first groove 21d. Regardless of the arrangement, when the first water-blocking structure 21f is a water-blocking rib, the water-blocking rib can extend along the width direction of the first groove 21a (the water-blocking rib can be perpendicular to the length direction of the water-receiving trough 21a) or extend in a direction inclined to the width direction of the first groove 21a (the water-blocking rib can be inclined relative to both the length and width directions of the water-receiving trough 21a). As an example, such as... Figure 9 As shown, the water-blocking rib extends in an inclined direction relative to the width direction of the first groove 21d to be obliquely connected to the groove wall on one side of the width of the first groove 21d, so that the two ends of the length of the water-blocking rib are a fixed end and a free end, respectively. The fixed end is connected to the groove side wall of the first groove 21d. In the length direction of the water receiving groove 21a, the free end of the water-blocking rib extends in a direction away from the water filling position, or the free end of the water-blocking rib extends in a direction toward the water filling position.

[0047] In some embodiments, such as Figure 3 , Figure 5 and Figure 9 As shown, the multiple distribution holes 21c of the water receiving tank 21a are equally spaced, and all distribution holes 21c are located on the same straight line, which facilitates processing. The water filling position 21b has multiple distribution holes 21c on both sides of the length of the water receiving tank 21a. The length of the first tank portion 21d is less than the length of the second tank portion 21e, and the number of distribution holes 21c corresponding to the first tank portion 21d is less than the number of distribution holes 21c corresponding to the second tank portion 21e. Therefore, the arrangement of the first tank portion 21d and the second tank portion 21e can achieve a good match with the arrangement of the distribution holes 21c, and it is less likely that large areas of the first tank portion 21d and the second tank portion 21e will not be without distribution holes 21c, making it easier to rationally utilize the arrangement space provided by the first tank portion 21d and the second tank portion 21e to arrange the distribution holes 21c.

[0048] In some embodiments, along the length of the water receiving tank 21a, the diameters of a plurality of distribution holes 21c located on the same side as the water filling position 21b increase in the direction away from the water filling position 21b. It is understood that the flow resistance at the distribution hole 21c with a relatively smaller diameter is greater than the flow resistance at the distribution hole 21c with a larger diameter. This arrangement facilitates the flow of water in the water receiving tank 21a towards the distribution holes 21c that are farther from the water filling position 21b, thereby further mitigating the leakage problem caused by excessively high local moisture content in the wet film 22.

[0049] Of course, in other embodiments, the apertures of the plurality of distribution holes 21c of the water receiving tank 21a are still set to be equal.

[0050] In some embodiments, such as Figure 5 and Figure 11 As shown, the bottom wall of the water receiving tank 21a extends downward from the water filling position 21b toward any of the distribution holes 21c. The bottom wall of the water receiving tank 21a has a certain guiding effect on the water. Under the action of gravity, the water is guided to the distribution hole 21c more quickly and is less likely to accumulate at the water filling position 21b. Moreover, even if the distribution hole 21c is far away from the water filling position 21b, the above arrangement can make the water flow as far away from the distribution hole 21c as possible from the water filling position 21b, which is conducive to improving the balance of water distribution among multiple distribution holes 21c.

[0051] It is understandable that the height of the bottom wall of the water receiving tank 21a corresponding to the location of the multiple distribution holes 21c can be the same or different. In other words, the upper edges of the multiple distribution holes 21c can be at the same height or at different heights.

[0052] In some embodiments, such as Figure 5 and Figure 11As shown, the water receiving tank 21a is divided by the water filling position 21b into a first tank portion 21d and a second tank portion 21e that are connected and arranged along the length direction of the water receiving tank 21a. The first tank portion 21d corresponds to at least one distribution hole 21c, and the second tank portion 21e corresponds to at least one distribution hole 21c. The bottom wall of the first tank portion 21d and the bottom wall of the second tank portion 21e extend downward from the water filling position 21b along the length direction. The water filling position 21b is provided with distribution holes 21c on both sides of the water receiving tank 21a along the length direction. The bottom wall of the water receiving tank 21a extends downward from the water filling position 21b toward both ends of its length direction.

[0053] As can be seen, the upper edges of the multiple distribution holes 21c can be at different heights. Along the length of the water receiving tank 21a, the upper edge of the distribution hole 21c that is closer to the water filling position 21b is higher than the upper edge of the distribution hole 21c that is farther from the water filling position 21b. This is beneficial to further enhance the ability of water to flow from the water filling position 21b toward the end of the water receiving tank 21a, increase the amount of water flowing to the distribution hole 21c that is farther from the water filling position 21b, and further improve the balance of water distribution among the multiple distribution holes 21c.

[0054] In some embodiments, such as Figure 5 and Figure 11As shown, the number of distribution holes 21c corresponding to the first trough 21d is less than the number of distribution holes 21c corresponding to the second trough 21e, and the length of the first trough 21d is less than the length of the second trough 21e. Therefore, the lengths of both the first trough 21d and the second trough 21e can be well matched with the number of corresponding distribution holes 21c, without imposing excessive restrictions on the arrangement spacing of the distribution holes 21c. This is especially true when multiple distribution holes 21c are equally spaced; the above arrangement of the first trough 21d and the second trough 21e is better suited. Simultaneously, due to the difference in the number of distribution holes 21c, the amount of water flowing from the self-filling position 21b to the second trough 21e needs to be slightly greater than the amount of water flowing from the self-filling position 21b to the first trough 21d. Therefore, the bottom of the first trough 21d... If the inclination angle of the wall is less than or equal to the inclination angle of the bottom wall of the second groove 21e, then the angle between the bottom wall of the first groove 21d and the horizontal plane is less than or equal to the angle between the bottom wall of the second groove 21e and the horizontal plane. This results in a first vertical drop between the end of the bottom wall of the first groove 21d furthest from the second groove 21e and its position at the water filling position 21b, and a second vertical drop between the end of the bottom wall of the second groove 21e furthest from the first groove 21d and its position at the water filling position 21b. The first drop is smaller than the second drop, which helps to ensure that the amount of water flowing from the water filling position 21b to the first groove 21d and the second groove 21e is appropriate, thereby further improving the water distribution of the multiple distribution holes 21c. For example, the first drop H1 is 0.5mm, and the second drop H2 is 1mm.

[0055] In some embodiments, such as Figure 4 , Figure 5 , Figure 10 and Figure 11 As shown, the processing component 2 also includes a water-absorbing element 24, which is disposed between the wet membrane 22 and the multiple distribution holes 21c. The water-absorbing element 24 has good water absorption capacity; for example, the water absorption capacity of the water-absorbing element 24 is better than that of the wet membrane 22. Water flowing from the multiple distribution holes 21c can first drip onto the water-absorbing element 24, where it is adsorbed and quickly diffuses. This allows the water-absorbing element 24 to redistribute the water remaining from the distribution holes 21c, improving the uniformity of the water flowing to the wet membrane 22. In other words, the water flowing from the multiple distribution holes 21c is first more evenly adsorbed onto the water-absorbing element 24, and then the water on the water-absorbing element 24 flows more evenly down to the wet membrane 22. This improves the uniformity of water distribution on the wet membrane 22, reduces the problem of excessively high or low local moisture content in the wet membrane 22, and improves the humidification effect of the wet membrane 22. The number of distribution holes 21c can be appropriately reduced. As an example, the water-absorbing element 24 is an absorbent sponge.

[0056] In some embodiments, such as Figures 10-12As shown, a wet membrane frame 23 is provided around the outer periphery of the wet membrane 22. The thickness of the wet membrane 22 is exposed on both sides of the wet membrane frame 23. The wet membrane frame 23 is positioned to avoid the distribution hole 21c, thus providing some support and protection for the wet membrane 22. At the same time, the wet membrane frame 23 does not block the water flowing down from the distribution hole 21c. The absorbent component 24 is located at the top of the wet membrane 22, between the wet membrane 22 and the wet membrane frame 23. The wet membrane frame 23 can provide some protection for the absorbent component 24 and facilitates the integration of the absorbent component 24 with the wet membrane 22, especially... This allows for better adaptation to situations where the processing component 2 can be pulled out; and / or, the fan assembly 3 is located downstream of the wet membrane 22. The processing component 2 also includes a first water-blocking element 25, which is located downstream of the water-absorbing element 24 and at the top of the wet membrane 22. In the airflow direction, the first water-blocking element 25 is located on the side of the water-absorbing element 24 that is relatively close to the fan assembly 3. The first water-blocking element 25 can block the water on the water-absorbing element 24 to a certain extent, reducing the probability that the water on the water-absorbing element 24 will be sucked into the fan assembly 3, causing problems such as water leakage and water blowing.

[0057] 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 assembly 2, when the fan assembly 3 is working, it can induce air to enter the air duct 1a, be processed by the processing assembly 2, and the processed air can be sent away via the fan assembly 3.

[0058] As an example, the top of the wet membrane frame 23 has a clearance hole 231a, which is vertically opposite to at least one distribution hole 21c. Water flowing down from the distribution hole 21c can flow through the clearance hole 231a onto the wet membrane 22. The wet membrane frame 23 includes two opposing first sidewalls 231 and two opposing second sidewalls 232. The two first sidewalls 231 are respectively located on the upper and lower sides of the wet membrane 22, and the two second sidewalls 232 are respectively located along the width of the wet membrane 22 (e.g., the width direction of the wet membrane 22 is...). Figure 3 On both sides of the first horizontal direction in the middle, the first sidewall 231 located on the upper side of the wet film 22 has a clearance hole, and the water absorption member 24 can be clamped between the first sidewall 231 located on the upper side of the wet film 22 and the wet film 22.

[0059] In some embodiments, such as Figure 4 , Figure 10 and Figure 12 As shown, the thickness of the wet film 22 (for example, the thickness direction of the wet film 22 is...) Figure 4At least its downstream side is covered with a primary filter screen 26 on both sides (in the second horizontal direction). Thus, the primary filter screen 26 can intercept water on the wet membrane 22, reducing the probability of water on the water suction element 24 being sucked into the fan assembly 3, causing problems such as water leakage and water blowing. Moreover, water on the wet membrane 22 can easily be drawn out as bubbles under the action of airflow. The primary filter screen 26 has densely arranged filter holes, which helps to reduce the formation of water bubbles on the wet membrane 22.

[0060] As an example, the primary filter 26 is bonded and fixed to the wet membrane 22; the outer periphery of the wet membrane 22 is provided with a wet membrane frame 23, which avoids the distribution hole 21c. The edge of the primary filter 26 is bonded and fixed to the wet membrane frame 23, which helps to improve the overall integrity of the processing component 2. Moreover, the edge of the primary filter 26 is usually prone to burrs, and the above-mentioned fixing method can cover the burrs to a certain extent.

[0061] In some embodiments, such as Figure 7 As shown, a first limiting part 21g is formed on the support 21. The first limiting part 21g is positioned and engaged with the downstream side of the lower end of the wet membrane 22, and / or the first limiting part 21g is positioned and engaged with the downstream side of the lower end of the wet membrane frame 23 surrounding the outer periphery of the wet membrane 22. Thus, the first limiting part 21g can restrict the tendency of the wet membrane 22 to move towards the downstream side under the action of airflow, thereby improving the reliability of the wet membrane 22's installation position.

[0062] The air handling unit 100 also has a second limiting part 3a, which limits the downstream side of the upper end of the wet film 22 and / or limits the downstream side of the lower end of the wet film frame 23 surrounding the outer periphery of the wet film 22. The second limiting part 3a can also limit the tendency of the wet film 22 to move towards the downstream side under the action of airflow, thereby improving the reliability of the wet film 22's installation position.

[0063] It is evident that the cooperation of the first limiting part 21g and the second limiting part 3a can restrict the tendency of the entire wet membrane 22 to move downstream under the action of airflow, effectively improving the reliability of the wet membrane 22's installation position and helping to improve the problem of the wet membrane 22 tilting or misaligning due to being sucked to the downstream side. If the fan assembly 3 is located downstream of the processing assembly 2, it helps to reduce the probability of water on the wet membrane 22 being sucked to the fan assembly 3, causing leakage or water blowing problems. Optionally, the second limiting part 3a is formed on the bracket 21, the housing 1, or the fan assembly 3, so the installation of the second limiting part 3a is flexible.

[0064] It is understood that the two sides of the thickness of the wet film 22 can be the upstream side and the downstream side of the wet film 22, respectively. When the outer periphery of the wet film 22 is provided with a wet film frame 23, either the first limiting part 21g or the second limiting part 3a can be limited and matched on the downstream side of the wet film frame 23 or on the downstream side of the wet film 22. When the outer periphery of the wet film 22 is not provided with a wet film frame 23, both the first limiting part 21g and the second limiting part 3a are limited and matched on the downstream side of the wet film 22.

[0065] In some embodiments, such as Figure 7 As shown, at least one of the first limiting part 21g and the second limiting part 3a includes a plurality of limiting protrusions 21h spaced apart along the length direction of the water receiving tank 21a. The plurality of limiting protrusions 21h respectively limit and cooperate at different positions of the wet film 22 in the length direction of the water receiving tank 21a, which helps to improve the limiting reliability of the entire wet film 22. At the same time, the length of each limiting protrusion 21h in the length direction of the water receiving tank 21a can be adapted to be shortened.

[0066] As an example, such as Figure 7 As shown, the first limiting portion 21g includes two limiting protrusions 21h, which are respectively located at both ends of the width of the wet film 22. Of course, at least one of the first limiting portion 21g and the second limiting portion 3a can also be configured as a single limiting protrusion 21h.

[0067] In some embodiments, such as Figure 4 and Figure 10 As shown, the processing component 2 also includes a second water-blocking member 27, which is located downstream of the wet membrane 22 and blocks the gap between the top of the wet membrane 22 and the support 21. It can be seen that the top of the second water-blocking member 27 is higher than the top of the wet membrane 22, and the bottom of the second water-blocking member 27 is lower than the top of the wet membrane 22, so that the top and bottom of the second water-blocking member 27 are respectively offset vertically from the top of the wet membrane 22. The second water-blocking member 27 spans the upper and lower sides of the gap between the top of the wet membrane 22 and the support 21. The second water-blocking member 27 can effectively block the water flowing from the distribution hole 21c to the wet membrane 22, improving the problem of water flowing down from the distribution hole 21c being blown away from the wet membrane 22 by the airflow, thus enhancing the humidification effect.

[0068] As an example, the outer periphery of the wet membrane 22 is provided with a wet membrane frame 23, and the thickness of the wet membrane 22 is exposed on both sides of the wet membrane frame 23. The wet membrane frame 23 is provided to avoid the distribution hole 21c. The second water-blocking member 27 is blocked in the gap between the top of the wet membrane 22 and the wet membrane frame 23, and is also blocked in the gap between the top of the wet membrane frame 23 and the bracket 21 at the distribution hole 21c.

[0069] In some embodiments, such as Figure 4 and Figure 10As shown, the processing component 2 also includes a water-absorbing element 24, which is disposed between the wet film 22 and the plurality of distribution holes 21c. The air processing component 100 also includes a first water-blocking element 25, which is located at the top of the wet film 22 and sandwiched between the water-absorbing element 24 and the second water-blocking element 27. The second water-blocking element 27 also blocks the gap between the top of the wet film 22 and the first water-blocking element 25, as well as the gap between the top of the wet film 22 and the water-absorbing element 24. The first water-blocking component 25 and the second water-blocking component 27 can form a double water-blocking protection; and / or, the air handling unit 100 also has a second limiting part 3a, which limits the second water-blocking component 27 on the side away from the wet film 22. Then the second water-blocking component 27 can be sandwiched between the wet film 22 and the second limiting part 3a. The second limiting part 3a restricts the tendency of the wet film 22 to move towards the downstream side through the second water-blocking component 27, without affecting the water-blocking effect of the second water-blocking component 27.

[0070] In some embodiments, such as Figure 1 and Figure 7 As shown, the water filling component 4 can be installed in the housing 1. The water filling component 4 is used to control the maximum liquid level in the water storage tank 1b to improve the problem of excessive water accumulation and easy overflow in the water storage tank 1b. As an example, the water filling component 4 includes a liquid level sensor, a water tank 41, and a water pump 42. The water tank 41 is used to add water to the water storage tank 1b, and the water pump 42 is used to transport the water in the water storage tank 1b to the water filling position 21b (for example, the water pump 42 transports water to the water filling position 21b through a water supply pipeline). The liquid level sensor is used to detect the liquid level in the water storage tank 1b, and the water tank 41 controls whether to add water to the water storage tank 1b according to the detection result of the liquid level sensor.

[0071] As an example, the liquid level in the water tank 1b refers to the vertical height or depth of the liquid actually contained in the water tank 1b, excluding the foam on the liquid surface in the water tank 1b. Foam is a low-density, porous material formed on the liquid surface 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.

[0072] like Figure 4 , Figure 6 and Figure 7 As shown, the air handling unit 100 also includes a second water-blocking structure 5, which is disposed in the housing 1 and located between the wet film 22 and the highest liquid level in the vertical direction, so as to block the dripping water of the wet film 22 and guide it to the bottom wall of the water storage tank 1b.

[0073] It is understandable that the water used for humidification of the wet membrane 22 may contain some impurities. If the impact force between the dripping water from the wet membrane 22 and the liquid surface in the water storage tank 1b is strong, foam is easily generated in the water storage tank 1b. This application addresses this by placing the second water-blocking structure 5 between the wet membrane 22 and the highest liquid level, so that the second water-blocking structure 5 can receive the dripping water from the wet membrane 22. At the same time, the second water-blocking structure 5 can guide the dripping water to the liquid surface of the water storage tank 1b. Compared with the dripping water from the wet membrane 22 falling directly onto the liquid surface of the water storage tank 1b, the setting of the second water-blocking structure 5 helps to reduce the impact force between the dripping water from the wet membrane 22 and the liquid surface in the water storage tank 1b. The drip drop of 22 makes it less likely for the air handling unit 100 to produce dripping noise. When the water falls from a lower height, the kinetic energy is reduced, the impact energy of the water drop is lower, and the impact force when it collides with the liquid surface is weakened. This helps to reduce the formation of foam, making it less likely for the air handling unit 100 to blow out foam. This reduces the possibility of the air handling unit 100 blowing water. At the same time, foam overflow is less likely to occur in the water storage tank 1b, which is less likely to affect the normal operation of other components and improves the reliability of the air handling unit 100.

[0074] It is understood that, in the vertical direction, the second water-blocking structure 5 can be located outside the water storage tank 1b, or inside the water storage tank 1b, or at the opening of the water storage tank 1b. This application does not limit the specific position of the second water-blocking structure 5 in the vertical direction, as long as the second water-blocking structure 5 can be located between the wet film 22 and the highest liquid level. In addition, the second water-blocking structure 5 can block part of the dripping water from the wet film 22, or block all of the dripping water from the wet film 22.

[0075] In some embodiments, such as Figures 5-7 As shown, the air handling unit 100 also includes a flow-through structure 6, which is disposed in the water storage tank 1b and defines a flow-through channel 6a. A second water-blocking structure 5 is fixedly connected to the flow-through structure 6 and covers the upper part of the flow-through channel 6a. As an example, the second water-blocking structure 5 covers the upper part of the center surface of the flow-through structure 6.

[0076] It can be seen that by setting the flow structure 6 in the water storage tank 1b, the fluid can flow through the flow channel 6a, which meets the water flow requirements. Compared with the scheme where the water storage tank 1b is empty and the flow structure 6 is not set in the water storage tank 1b, the setting of the flow 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 1b and / or improving the overflow of water in the water storage tank 1b caused by airflow.

[0077] As an example, the flow channel 6a can extend in a serpentine manner along the length of the water storage tank 1b; if the water in the water storage tank 1b is transported to the water filling position 21b by the water pump 42, the flow channel 6a will not affect the flow of water in the water storage tank 1b toward the water pump 42.

[0078] In some embodiments, such as Figure 7 As shown, the water supply assembly 4 includes a water tank 41 and a water pump 42. The water tank 41 is used to add water to the water storage tank 1b, and the water pump 42 is used to transport the water in the water storage tank 1b to the water supply position 21b, so that the dripping water of the wet membrane 22 can be reused. The water storage tank 1b has a critical water supply level R. The water tank 41 is configured to add water when the water level in the water storage tank 1b is lower than the critical water supply level R, and to stop adding water when the water level in the water storage tank 1b reaches the critical water supply level R. The critical water supply level R is lower than or equal to the highest level.

[0079] Therefore, the water storage tank 1b can have a suitable amount of water, the water storage tank 1b is not prone to overflow risk, and it is also beneficial to reduce the water blowing phenomenon of the fan assembly 3 to a certain extent. Moreover, when the water level in the water storage tank 1b is higher than the critical water replenishment level R, the water pump 42 can accelerate the water supply to the wet membrane 22 so that the water level in the water storage tank 1b is not too high and the risk of water blowing is not likely to occur.

[0080] It is understandable that the wet film 22 drips relatively little water into the water storage tank 1b during humidification, so that the water level in the water storage tank 1b is not likely to exceed the critical replenishment level R by too much, thereby reducing the risk of water blowing into the air handling unit 100 and improving the reliability of the air handling unit 100.

[0081] In some embodiments, such as Figures 5-7 As shown, the water storage tank 1b extends into a long strip along the length of the water receiving tank 21a. The shell 1 also defines a water injection tank 1c, which is connected to one end of the length of the water storage tank 1b. The water tank 41 is located above the water injection tank 1c and includes a tank body 411 and a water outlet valve 412. The water outlet valve 412 is located at the bottom of the tank body 411 and includes a valve seat 4121 and a valve core 4122. The valve core 4122 is positioned relative to the valve seat 411. 21 is movable between the open valve state and the closed valve state. The valve seat 4121 includes a surrounding part 4121a located outside the housing 411. The surrounding part 4121a surrounds a receiving groove 4121b with the groove opening facing downward. A protrusion 1d is formed on the bottom wall of the water injection tank 1c. The protrusion 1d extends into the receiving groove 4121b and abuts against the part of the valve core 4122 located outside the housing 411, so that the valve core 4122 is kept in the open valve state.

[0082] As an example, the valve seat 4121 has an outlet that connects the housing 411 and the receiving groove 4121b. The outlet valve 412 is located at the bottom of the housing 411 so that the valve core 4122 can be engaged with the valve seat 4121 under gravity. The valve core 4122 is blocked at the outlet, and the outlet valve 412 is in the closed state. When the protrusion 1d abuts against the part of the valve core 4122 located outside the housing 411, so that the valve core 4122 and the valve seat 4121 are no longer engaged, the valve core 4122 opens the outlet. For example, the protrusion 1d can push the valve core 4122 to move away from the outlet along the axial direction of the outlet valve 412, so that the valve core 4122 and the valve seat 4121 are no longer engaged, and the outlet valve 412 is in the open state.

[0083] In some examples, the height of the opening of the receiving tank 4121b corresponds to the critical replenishment level R. The tank 411 is connected to the water injection tank 1c through the opening of the receiving tank 4121b. Combined with the connection between the water injection tank 1c and the water storage tank 1b, the liquid levels of the water injection tank 1c and the water storage tank 1b can be kept consistent. When the water level of the water storage tank 1b is lower than the critical replenishment level R, the opening of the receiving tank 4121b is above the water level of the water storage tank 1b, so that air can indirectly enter the tank 411 through the opening of the receiving tank 4121b. The tank 411 will add water to the water injection tank 1c until the water level of the water storage tank 1b reaches the height of the opening of the receiving tank 4121b, or until the water in the water storage tank 1b completely submerges the opening of the receiving tank 4121b. When the water level in the water storage tank 1b is higher than the height of the opening of the receiving tank 4121b, air cannot indirectly enter the box 411 through the opening of the receiving tank 4121b, and the box 411 will not add water to the water filling tank 1c.

[0084] In some examples, the enclosure 4121a has a connecting notch to connect the inner and outer sides of the receiving tank 4121b. The height of the connecting notch corresponds to the critical replenishment level R. The enclosure 4121a is a tubular structure, and the space enclosed by the enclosure 4121a is the inner side of the receiving tank 4121b, while the outer side of the enclosure 4121a is the outer side of the receiving tank 4121b. Similarly, when the water level in the water storage tank 1b is lower than the critical replenishment level R, the part of the connecting notch is above the water level in the water storage tank 1b, so that air can indirectly enter the tank 411 through the connecting notch 4121c. The tank 411 will add water to the water filling tank 1c until the water level in the water storage tank 1b reaches the height of the connecting notch, or in other words, until the water in the water storage tank 1b completely submerges the connecting notch. When the water level in the water storage tank 1b is higher than the height of the connecting port 4121c, that is, when the water level in the water storage tank 1b is higher than the top of the connecting port 4121c, air cannot indirectly enter the box 411 through the connecting port 4121c, and the box 411 will not add water to the water filling tank 1c.

[0085] It is understandable that the box 411 is connected to the water injection tank 1c through the connecting port 4121c. At this time, the water level in the water injection tank 1c and the water storage tank 1b is related to the height position of the connecting port 4121c, but not to the position of the opening of the receiving tank 4121b. This helps to reduce the restriction on the position of the opening of the receiving tank 4121b. For example, the height position of the opening of the receiving tank 4121b can be higher than, lower than or equal to the height position of the connecting port 4121c.

[0086] In some embodiments, the processing component 2 further includes a purification element 28 disposed upstream of the wet membrane 22. The purification element 28 can filter out dust and impurities in the air, ensuring that the air flowing towards the wet membrane 22 is cleaner and improving the humidification effect. At the same time, it can prevent humid air from contacting the purification element, which could affect its filtration performance or cause blockage, reducing the risk of damage to the purification element 28 due to humid air and extending its service life.

[0087] For example, the purification component 28 includes a first filter and a second filter, which are arranged sequentially along the airflow direction. The first and second filters are made of different materials, allowing for different filtration effects on particles of different sizes and / or for filtering different types of impurities. For instance, the first filter is a HEPA filter, and the second filter is a manganese mesh. The HEPA filter is primarily used to filter fine particulate matter in the air, such as dust, pollen, bacteria, and viruses, effectively capturing particles with a diameter of several micrometers or larger. The HEPA filter has 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 component 100.
