[0011] The upper end of the water distribution hole of the second water distribution plate protrudes from the bottom of the water storage tank.

[0012] In one embodiment, the water supply pipe is provided at the middle part of the water storage tank;

[0013] Corresponding to the water storage tank, there are two water outlets, and the two water outlets are in opposite directions.

[0014] In one embodiment, the wet curtain assembly further includes a sealing cover that covers the water storage tank of the first water distribution plate.

[0015] In one embodiment, the opening area of ​​the water outlet corresponding to each of the water distribution plates increases sequentially from bottom to top.

[0016] In one embodiment, the wet curtain assembly further includes a base disposed below the plurality of curtain cores, the base having drainage holes.

[0021] The water distribution pipe has its lower end connected to the upper port, and its upper end forms the water outlet corresponding to the first water distribution plate.

[0022] In one embodiment, the water inlet pipe is detachably connected to the upper port; and / or,

[0023] The water distribution pipe is detachably connected to the lower port.

[0024] In one embodiment, the curtain core is provided with a clearance portion, and the clearance portions of the plurality of curtain cores define a clearance space, and the water supply pipe fitting is disposed in the clearance space.

[0025] In one embodiment, the curtain core is made of a hydrophobic material; and / or,

[0026] The curtain core is made of plastic or metal.

[0027] The present invention also proposes a humidifier, comprising:

[0028] The housing has an air inlet, an air outlet, and a ventilation channel connecting the air inlet and the air outlet;

[0029] The evaporative cooling pad assembly is the aforementioned evaporative cooling pad assembly, which is disposed within the ventilation channel;

[0030] A water tank, disposed within the housing, is used to deliver humidifying water to the water inlet via a conveying device; and...

[0031] The fan assembly is used to drive airflow from the air inlet into the housing, then through the flow passage and the ventilation passage, and finally out from the air outlet.

[0032] In the technical solution of the present invention, a plurality of curtain cores are stacked vertically. The inner sides of the plurality of curtain cores define an air outlet duct extending vertically. A flow passage is formed between two adjacent curtain cores, and the flow passage communicates with the air outlet duct. Each curtain core is provided with a vertically penetrating water passage hole, so that humidifying water can flow from top to bottom through the plurality of curtain cores. At least two water distribution trays include a first water distribution tray and at least one second water distribution tray. The first water distribution tray is disposed above the plurality of curtain cores, and the second water distribution tray is disposed between two of the curtain cores. The water supply pipe has a water inlet and at least two water outlets. The water inlet is used to allow humidifying water to flow in, and the at least two water outlets correspond to the at least two The water distribution tray is configured such that, during use, water is supplied to each of the water distribution trays through the outlets of the water supply pipes. The first water supply tray at the top provides humidifying water to the uppermost wet curtain through the water distribution holes. The humidifying water flows downward along the water passage holes, gradually filling the surface of each wet curtain with moisture. When the airflow passes through the flow passage, it becomes filled with moisture and then exits through the air outlet duct, humidifying the air. As the humidifying water in the first water distribution tray flows downward, less and less water is supplied to the lower curtain cores. The second water distribution tray ensures that the lower curtain cores also have sufficient moisture, thus improving the uniformity of water distribution to each curtain core and improving humidification efficiency.

[0049] Humidifiers are an important means of regulating humidity and improving comfort in the home environment. The evaporative cooling pad is the core component of a humidifier. As the demand for large humidification capacity increases, the size of the evaporative cooling pads is also getting larger, and the height of some evaporative cooling pads is also getting higher. This can easily cause water to be present in the upper part but not in the lower part, or result in uneven humidification, affecting the overall humidification efficiency.

[0050] The main objective of this invention is to provide a wet curtain assembly and a humidifier, which aims to at least solve the problem of poor humidification efficiency caused by uneven water distribution in the wet curtain in related technologies.

[0051] Please see Figures 1 to 3In one embodiment of the present invention, the evaporative cooling pad assembly 100 includes a plurality of curtain cores 1, at least two water distribution trays 2, and a water supply pipe 3. The plurality of curtain cores 1 are stacked vertically. The curtain cores 1 are made of a water-resistant material. The inner sides of the plurality of curtain cores 1 define an air outlet duct 101 extending vertically. An overflow channel 102 is formed between two adjacent curtain cores 1. The overflow channel 102 communicates with the air outlet duct 101. Each curtain core 1 is provided with a vertically penetrating water passage hole so that humidifying water can flow from top to bottom through the plurality of curtain cores 1. The water distribution trays... 2 is used to hold humidification water, and the water distribution plate 2 is provided with water distribution holes 21 for supplying humidification water to the wet curtain below. The at least two water distribution plates 2 include a first water distribution plate 201 and at least one second water distribution plate 202. The first water distribution plate 201 is disposed above the plurality of curtain cores 1, and the second water distribution plate 202 is disposed between two of the curtain cores 1. The water supply pipe 3 has a water inlet 3a and at least two water outlets 3b. The water inlet 3a is used to allow humidification water to flow in, and the at least two water outlets 3b are provided corresponding to the at least two water distribution plates 2.

[0052] In the technical solution of the present invention, a plurality of curtain cores 1 are stacked in the vertical direction. The inner side of the plurality of curtain cores 1 defines an air outlet duct 101 extending in the vertical direction. An overflow channel 102 is formed between two adjacent curtain cores 1. The overflow channel 102 communicates with the air outlet duct 101. Each curtain core 1 is provided with a vertically penetrating water passage hole so that humidifying water can flow from top to bottom through the plurality of curtain cores 1. At least two water distribution plates 2 include a first water distribution plate 201 and at least one second water distribution plate 202. The first water distribution plate 201 is disposed above the plurality of curtain cores 1, and the second water distribution plate 202 is disposed between two of the curtain cores 1. The water supply pipe 3 has a water inlet 3a and at least two water outlets 3b. The water inlet 3a is used to allow humidifying water to flow in, and the at least two water outlets... 3b corresponds to the at least two water distribution trays 2; thus, during use, water is supplied to each of the water distribution trays 2 through the water outlets 3b of the water supply pipe 3. The first water supply tray at the top provides humidifying water to the uppermost wet curtain through the water distribution hole 21. The humidifying water flows downward along the water passage hole, so that the surface of each wet curtain gradually fills with water. When the airflow passes through the flow passage 102, it will be filled with water, and then it will exit from the air outlet duct 101 to humidify the air. As the humidifying water in the first water distribution tray 201 flows downward, it will cause less and less water to be supplied to the lower curtain core 1. The setting of the second water distribution tray 202 will ensure that the lower curtain core 1 also has enough water. This can improve the uniformity of water distribution to each curtain core 1, thereby improving the humidification efficiency.

[0053] The material of the curtain core 1 can be plastic or other water-resistant materials, so that the main body of the curtain core 1 can be removed for washing and recycling.

[0054] The number of the second water distribution trays 202 can be one, two, or even more. The number of the second water distribution trays 202 will vary depending on the number of curtain cores 1 and the overall height. In a specific embodiment, please refer to... Figure 2 There are two second water distribution trays 202. It should be noted that the number of curtain cores 1 between the first water distribution tray 201 and the second water distribution tray 202 can be one or many; when there are two second water distribution trays 202, the number of curtain cores 1 between two adjacent second water distribution trays 202 can be one or many; specifically, it can be reasonably set according to the design height of the humidifier and the humidification effect.

[0055] The material of the curtain core 1 includes hydrophobic materials, and can be set as plastic or other rigid materials, so that the curtain core 1 can be removed for rinsing and cleaning, and can be recycled.

[0056] It is understandable that if only one water distribution hole 21 is provided on each of the water distribution plates 2, the water distribution efficiency of the water distribution plate 2 will be poor. Of course, the water distribution hole can be set to be very large to improve the water distribution efficiency, but this will make it difficult for the humidifying water to pass through the entire water distribution hole, that is, only a part of the water distribution hole will flow to the curtain core 1 below, resulting in uneven water distribution on a single curtain core 1.

[0057] Therefore, in this embodiment of the invention, a water storage tank 22 is provided on the upper surface of the water distribution plate 2. The water storage tank 22 is connected to the water passage hole and the corresponding water outlet 3b. For each water storage tank 22, multiple water passage holes are provided, and the multiple water passage holes are spaced apart along the length extension direction of the water storage tank 22. In this way, each water storage tank 22 corresponds to multiple water passage holes. After the water flows through the water storage tank 22, it is evenly distributed to the surface of the curtain core 1 through the spaced-apart water passage holes, avoiding uneven local drying and wetting, enhancing the stability of water distribution, and ensuring the efficiency of water distribution.

[0058] This invention does not limit the specific shape of the curtain core 1; it can be a block structure, a sheet structure, etc. In this embodiment, please refer to... Figure 4 and Figure 5To increase airflow, the curtain core 1 is arranged in a ring shape, with multiple water inlets spaced apart along the circumference of the curtain core 1. The shape of the water distribution plate 2 corresponds to that of the curtain core 1. For example, when the curtain core 1 is arranged in a ring shape, the water distribution plate 2 is also arranged in a ring shape to ensure the consistency of the overall structure. At the same time, the water storage tank 22 is also arranged in a ring shape, and the multiple water inlets are distributed in a ring shape.

[0059] It is understandable that if the upper end of the water distribution hole 21 is flush with or lower than the bottom of the water storage tank 22, when water enters the water storage tank 22 through the water outlet 3b, it will directly exit from the adjacent water distribution hole 21 instead of being stored in the water storage tank 22. Even if the water inflow into the water storage tank 22 is greater than the water outflow from the water distribution hole 21, it will result in a larger amount of water flowing out of the water distribution hole 21 closest to the water outlet 3b, affecting the overall uniformity of water distribution.

[0060] Therefore, in the embodiments of the present invention, please refer to Figure 6 and Figure 7 The upper end of the water distribution hole 21 of the first water distribution plate 201 protrudes beyond the bottom of the water storage tank 22. This arrangement allows the water storage tank 22 of the first water distribution plate 201 to initially store a certain amount of water. When the water level in the water storage tank 22 exceeds the upper end of the water distribution hole 21, water will flow out simultaneously from multiple water distribution holes 21, with the water volume being approximately the same. This ensures that each part of the curtain core 1 below receives approximately the same amount of humidifying water, guaranteeing humidification efficiency. Of course, the upper end of the water distribution hole 21 needs to be lower than the opening of the water storage tank 22.

[0061] Similarly, the upper end of the water distribution hole 21 of the second water distribution plate 202 protrudes from the bottom of the water storage tank 22.

[0062] It should be noted that the two schemes, "the upper end of the water distribution hole 21 of the first water distribution plate 201 protrudes from the bottom of the water storage tank 22" and "the upper end of the water distribution hole 21 of the second water distribution plate 202 protrudes from the bottom of the water storage tank 22", can exist individually or simultaneously.

[0063] The methods for improving the uniformity of water distribution from multiple water distribution holes 21 are not limited to this. In some embodiments, the water supply pipe 3 is positioned at the middle of the water storage tank 22; for each water storage tank 22, there are two water outlets 3b, and the two water outlets 3b face opposite directions. Compared to a single water outlet 3b, whether positioned at the middle or end of the water storage tank 22, filling each water distribution hole 21 takes a considerable amount of time. By having two water outlets 3b facing opposite directions, the water flows symmetrically from the middle and diffuses evenly along both sides of the water storage tank 22, eliminating the flow deviation caused by water exiting from one side and further improving the uniformity of water distribution.

[0064] It is understandable that, for the second water distribution tray 202, since it is located between the two curtain cores 1 and there is at least one curtain core 1 above it, the upper end of the water storage tank 22 does not need to be sealed. In this way, the water storage tank 22 of the second water distribution tray can still receive water left from the curtain core 1 above. As for the first water distribution tray 201, it does not need to receive water left from the curtain core 1 above, and only supplies water through the outlet 3b of the water supply pipe 3. Therefore, the wet curtain assembly 100 also includes a sealing cover 4, which covers the water storage tank 22 of the first water distribution tray 201. By sealing the water storage tank 22 of the first water distribution tray 201 with the sealing cover 4, the possibility of impurities falling into the water storage tank 22 and affecting water quality can be reduced.

[0065] The sealing cover 4 and the first water distribution plate 201 can be either fixedly connected or detachably connected, thus facilitating disassembly for cleaning of the water storage tank 22. When the sealing cover 4 and the first water distribution plate 201 are detachably connected, it can be through a snap-fit, a screw, or a magnetic attraction; this application does not impose any limitations on this.

[0066] It should be noted that if water is distributed among the multiple curtain cores 1 solely through the first water distribution plate 201, the upper curtain core 1 will have more water, while the lower curtain core 1 will have less water. However, when the second water distribution plate 202 is provided to replenish water to the lower curtain core 1, since the lower curtain core 1 has its own water supply from the water distribution plate 2, and the water flowing down from the upper curtain core 1 will also enter the lower curtain core 1, this will actually result in the lower curtain core 1 having more water.

[0067] To further improve the uniformity of water distribution, in this embodiment of the invention, the opening area of ​​the water outlet 3b corresponding to each of the water distribution plates 2 increases sequentially from bottom to top. In this way, the higher the water distribution plate 2 is, the more water it receives from the water supply pipe 3. During use, this can compensate for the water distribution difference caused by the lower layer of the curtain core 1 also receiving water flowing down from the upper layer of the curtain core 1, so as to make the humidification water distributed to each layer of the curtain core 1 basically the same, ensuring the uniformity of water distribution and humidification efficiency.

[0068] It is understandable that the water supply pipe 3 can transport water from bottom to top or from top to bottom. For the humidifier, a water tank 300 is provided to supply humidification water. The water supply pipe 3 transports the water in the water tank 300 to each of the water distribution trays 2. Since the water in the curtain core 1 flows downwards, the water tank 300 is usually located below multiple curtain cores 1 to receive the flowing humidification water. If the water supply pipe 3 transported water from top to bottom, it would make the overall pipeline more complex. Therefore, the water supply pipe 3 is usually designed to transport water from bottom to top. The opening area of ​​the water outlet 3b corresponding to each of the water distribution trays 2 increases sequentially from bottom to top, which can also compensate for the water pressure attenuation caused by gravity in the upper layer, reducing the problem of water flowing through the lower curtain core 1 while the upper curtain core 1 lacks water.

[0069] Of course, the opening area of ​​the water outlet 3b corresponding to each of the water distribution plates 2 can also be the same. Especially when there are a large number of water distribution plates 2, the shape of each water distribution plate 2 can be kept consistent, and the production cost is lower.

[0070] In order to support the plurality of said curtain cores 1, in an embodiment of the present invention, please refer to Figure 8 The wet curtain assembly 100 also includes a base 5 disposed below the plurality of curtain cores 1. The base 5 is provided with drainage holes. The base 5 supports the plurality of curtain cores 1. At the same time, the drainage holes allow the water from the plurality of curtain cores 1 to flow into the water tank 300 for recycling.

[0071] Furthermore, in order to restrict the horizontal movement of the multiple curtain cores 1 and the water distribution trays 2, in this embodiment, a limiting frame is provided on the upper surface of the base 5, located around the multiple curtain cores 1 and the water distribution trays 2. The setting of the limiting frame restricts the horizontal movement of the curtain cores 1 and the water distribution trays 2, so that the overall structure remains stable. At the same time, when assembling the wet curtain assembly 100 with the humidifier, the multiple curtain cores 1 and the water distribution trays 2 can be assembled with the base 5 and the limiting frame first, and then the entire wet curtain assembly 100 can be assembled through the base 5, which is more convenient.

[0072] Considering that the flow channels 102 are formed between adjacent curtain cores 1, the limiting frame needs to avoid obstructing the flow channels 102 as much as possible to ensure the airflow area of ​​the flow channels 102 and thus ensure the humidification efficiency of the humidifier. Therefore, the limiting frame includes multiple support ribs extending in the vertical direction, with gaps between adjacent support ribs to avoid obstructing the flow channels 102. Of course, to improve the stability of the limiting frame, a frame is also provided at the upper end of the multiple support ribs, connecting the multiple support ribs through the frame to ensure the stability of each support rib, thereby improving the stability of the limiting frame.

[0073] To ensure the consistency of the overall structure, the water supply pipe 3 extends in the vertical direction and is located between the base 5 and the first water distribution plate 201. This arrangement ensures that the water supply pipe 3 does not protrude from the overall wet curtain assembly 100, making the overall structure more compact and easier to install.

[0074] To allow the water supply pipe 3 to be positioned on the base 5 and the first water distribution plate 201, in one embodiment, the base 5 and the first water distribution plate 201 can be made slightly larger than the curtain core 1; in another embodiment, the curtain core 1 is provided with a clearance portion 11, and the clearance portions 11 of multiple curtain cores 1 define a clearance space, in which the water supply pipe 3 is positioned. Of these two methods, the first method simplifies the processing of a single curtain core 1 and reduces costs, while the method with the clearance portion 11 allows for a larger size of a single curtain core 1 and better humidification effect when the overall dimensions of the wet curtain assembly 100 are fixed.

[0075] The avoidance part 11 can be an avoidance hole provided on the curtain core 1, or it can be a notch provided on one side of the curtain core 1.

[0076] The water supply fitting 3 can take various forms. In some embodiments, the water supply fitting 3 can be configured as a single water pipe, with openings on the pipe serving as inlet 3a and outlet 3b. While this method simplifies the formation of the water supply fitting 3, it makes connecting it to multiple water distribution trays 2 more complicated. The outlet 3b needs to be opened on the side wall of the water pipe. If the outlet 3b corresponding to the second water distribution tray 202 is not directly connected to the second water distribution tray 202, the water at that outlet 3b is prone to splashing. If connected, the entire water supply fitting 3 needs to be connected to multiple water distribution trays 2 simultaneously in multiple directions, which presents certain difficulties. The connection becomes even more complicated when each water distribution tray 2 has two outlets 3b.

[0077] In the embodiments of the present invention, please refer to Figure 2 , Figure 4 and Figure 5 The water supply pipe fitting 3 includes at least one connecting pipe fitting 31, an inlet pipe 32, and a branch pipe 33. The connecting pipe fitting 31 is disposed on the second branch plate 202. The connecting pipe fitting 31 has an upper port 311, a lower port 312, and a side port 313. The side port 313 forms the outlet 3b corresponding to the second branch plate 202. The upper end of the inlet pipe 32 is connected to the lower port 312, and the lower end is used to supply humidification water. The lower end of the branch pipe 33 is connected to the upper port 311, and the upper end forms the outlet 3b corresponding to the first branch plate 201.

[0078] In this embodiment, the water supply pipe 3 is fixedly mounted on the second water distribution plate 202. When connecting the second water distribution plate 202 and the first water distribution plate 201, the water distribution pipe 33 can be directly connected in the vertical direction. Similarly, when connecting the inlet pipe 32 and the water tank 300, the connection is also only required in the vertical direction, making the overall structure more convenient to connect. After the humidifying water enters from the lower end of the inlet pipe 32, it flows along the inlet pipe 32 to the lower port 312 of the connecting pipe 31 on the second water distribution plate 202. A portion of the water flows from the side port 313 to the second water distribution plate 202, and another portion flows from the upper port 311 to the water distribution pipe 33, and then flows to the first water distribution plate 201.

[0079] It should be noted that when there are two or more second water distribution plates 202, the water supply pipe 3 also includes an intermediate pipe. The lower end of the intermediate pipe is connected to the upper port 311 of the connecting pipe 31 of the lower second water distribution plate 202, and the upper end is connected to the lower port 312 of the connecting pipe 31 of the upper second water distribution plate 202.

[0080] To facilitate cleaning of the water distribution trays 2, in this embodiment, the water inlet pipe 32 is detachably connected to the upper port 311, and the water distribution pipe 33 is detachably connected to the lower port 312. This allows the multiple water distribution trays 2 to be completely separated, making cleaning more convenient.

[0081] Of course, when there are multiple second water distribution plates 202, the intermediate pipe is detachably connected to at least one of the connecting pipes 31 at both ends.

[0082] This invention also proposes a humidifier, please refer to [reference needed]. Figure 9 The humidifier includes a wet curtain assembly 100. The specific structure of the wet curtain assembly 100 is as described in the above embodiments. Since this humidifier adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0083] Specifically, the humidifier also includes a housing 200, a fan assembly 400, and a water tank 300. The housing 200 has an air inlet, an air outlet, and a ventilation channel connecting the air inlet and the air outlet. The wet curtain assembly 100 is disposed in the ventilation channel. The water tank 300 is disposed in the housing 200. The water tank 300 is used to transport humidifying water to the water inlet 3a through a conveying device. The fan assembly 400 is used to drive airflow from the air inlet into the housing 200, then flow through the flow passage 102 and the ventilation channel in sequence, and finally flow out from the air outlet.

[0084] The air inlet on the housing 200 should be provided corresponding to the wet curtain assembly 100, and the part of the housing 200 corresponding to the fan assembly 400 should not be provided with an air inlet. This is to avoid the air flowing directly from the fan assembly 400 without passing through the wet curtain assembly 100, thus avoiding ineffective humidification.
