Technical Field

[0003] The present application relates to the technical field of household electrical appliances, and in particular to a wet curtain assembly and a humidifier. Background Art

[0004] With the advancement of society and the improvement of living standards, humidifiers, a household appliance used to increase indoor humidity, have been widely used in people's production and life, effectively improving people's living environment. As one of the core components of an evaporative humidifier, the wet curtain (also known as the evaporation filter) works by blowing the moisture on the wet curtain to evaporate, and the air carrying the moisture evaporates to the outside world, thereby increasing the ambient humidity.

[0005] Currently, most evaporative humidifiers on the market use a water pump to pump water down through the wet curtain. However, this method places high demands on the liquid distribution unit and the wet curtain, requiring the liquid distribution unit and the wet curtain to work together to fully moisten the wet curtain and maximize humidification. However, due to the existing liquid distribution unit and wet curtain structure, the wet curtain is often not evenly moistened, which prevents the desired humidification effect and affects the user experience of the humidifier.

[0006] Summary of the Invention

[0007] Based on this, it is necessary to provide a wet curtain assembly and a humidifier to address the problems of uneven water distribution in the liquid distribution unit and low wetness of the wet curtain.

[0010] A wet curtain, provided on one side of the liquid distribution unit in the first direction and connected to the drain hole;

[0011] Wherein, the drain hole is polygonal.

[0013] In one embodiment, the drain hole is rectangular.

[0014] In one embodiment, the distance between two adjacent drain holes is 4mm-11mm.

[0015] In one embodiment, the wet curtain includes a wet curtain body, and the wet curtain body includes a plurality of laminates. All the laminates are connected end to end in a second direction perpendicular to the first direction, and the spacing between two adjacent laminates is 3mm-5mm.

[0016] In one embodiment, the wet curtain body is formed of fiber paper.

[0017] In one embodiment, at least part of the laminates are provided with a plurality of spaced-apart water-puncture holes, and the diameter of each water-puncture hole is 1.5 mm to 2 mm.

[0018] In one embodiment, the wet curtain further includes at least two fixed ribs formed on the wet curtain body, all of the fixed ribs are arranged at intervals along the first direction, each of the fixed ribs extends along the second direction, and the spacing between two adjacent fixed ribs is 25.4 mm or 50.8 mm.

[0019] In one embodiment, the wet curtain assembly further includes a wet curtain base, the liquid distribution unit is installed on one side of the wet curtain base in the first direction, an installation cavity is defined between the wet curtain base and the liquid distribution unit, and the installation cavity is provided with an insertion port on one side in a second direction perpendicular to the first direction, and the wet curtain is inserted into the installation cavity from the insertion port along the second direction.

[0020] In one embodiment, the liquid distribution unit has a surface on one side facing the wet curtain protruding with a guide edge surrounding each of the drain holes, and the liquid distribution unit has a surface on one side facing the wet curtain protruding with a guide rib, one end of the guide rib is connected to the guide edge of the drain hole closest to the insertion port, and the other end of the guide rib extends along the second direction toward the insertion port.

[0037] Referring to Figure 1, which illustrates a schematic structural diagram of a wet curtain assembly in accordance with one embodiment of the present application, a humidifier (not shown) provided in accordance with one embodiment of the present application comprises an air duct assembly, a wet curtain assembly 100, a water pump, and other components. The wet curtain assembly 100 is disposed at the air outlet of the air duct assembly, and the water pump is connected to the wet curtain assembly 100 to supply water to the wet curtain assembly 100.

[0038] In this way, during the operation of the humidifier, the water pump draws the water in the water tank into the wet curtain assembly 100, and the airflow generated by the air duct assembly enters the wet curtain assembly 100 at its outlet, carrying the water evaporated from the wet curtain assembly 100 and then flowing out of the wet curtain 60, thereby helping to increase the humidity of the environment.

[0039] It should be noted that the specific structure of the air duct assembly, water pump and other components does not belong to the main invention of this application, so it will not be described here in detail. Air duct assemblies and water pumps with different structures can be selected according to needs.

[0040] Please continue to refer to Figure 1. The wet curtain assembly 100 includes a wet curtain base 20, a liquid distribution unit 40, and a wet curtain 60. The wet curtain base 20 is a hollow shell-like structure, including a base bottom wall and a base side wall extending from the edge of the base bottom wall in the same direction. In the following embodiments, the height direction of the wet curtain base 20 is defined as the first direction (i.e., the Z direction in Figure 1), the length direction of the wet curtain base 20 is defined as the second direction (i.e., the X direction in Figure 1), and the width direction of the wet curtain base 20 is defined as the third direction (i.e., the Y direction in Figure 1). The first direction, the second direction, and the third direction intersect with each other. As a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0041] Furthermore, an evaporation port 21 communicating with the external environment is provided on one side of the base side wall in the third direction, and an insertion port communicating with the evaporation port 21 is provided on one side of the base side wall in the second direction. The wet curtain 60 can be installed in the wet curtain base 20 through the insertion port and exposed to the external environment through the evaporation port 21. The airflow formed by the air duct assembly can flow through the evaporation port 21.

[0042] The liquid distribution unit 40 is mounted on the end of the wet curtain base 20 that is distal from the bottom wall of the wet curtain 60 in the first direction and is located at the top of the wet curtain base 20. A mounting cavity for accommodating the wet curtain 60 is defined between the wet curtain base 20 and the liquid distribution unit 40. A mounting groove 41 having a bottom wall is formed on the side of the liquid distribution unit 40 that faces away from the base bottom wall. A water injection hole 412 is defined on the bottom wall of the mounting groove 41 on the side distal from the mounting opening in the third direction. A plurality of drain holes 414 are defined on the bottom wall of the mounting groove 41 on the side proximal to the mounting opening in the third direction. All drain holes 414 are arranged at intervals. A water pump can inject water into the mounting groove 41 through the water injection hole 412, and water in the mounting groove 41 flows out through the drain holes 414.

[0043] The wet curtain 60 is a generally rectangular parallelepiped structure. It is inserted into the wet curtain base 20 along the second direction from the insertion opening of the wet curtain base 20 and positioned within the mounting cavity. The wet curtain 60 extends longitudinally along the second direction, its height along the first direction, and its thickness along the third direction. The wet curtain 60 is positioned on one side of the liquid distribution unit 40 in the first direction and is connected to the drain hole 414 of the liquid distribution unit 40. Therefore, water flowing out of the drain hole 414 flows into the wet curtain 60 for liquid distribution.

[0044] During operation, the end of the wet curtain 60 connected to the drain hole 414 in the first direction receives water, which diffuses and spreads throughout the wet curtain 60, thereby improving the evaporation efficiency and enhancing the humidification effect. The water can be transported through gaps such as capillaries within the wet curtain 60 or can flow along the surface of the wet curtain 60 under the action of gravity.

[0045] As described in the background, the existing wet curtain 60 is prone to uneven wetting, which affects the humidification of the wet curtain assembly 100 and, in turn, the user experience of the humidifier. The applicant has discovered through research that the main cause of this problem is that the drain holes 414 on the existing liquid distribution unit 40 are typically circular with a small diameter. As water in the mounting groove 41 flows through the drain holes 414 into the wet curtain 60, surface tension is easily generated, causing the water to form a liquid that blocks the drain holes 414, resulting in uneven water distribution and, ultimately, uneven wetting of the wet curtain 60.

[0046] Based on the above problems, please refer to Figure 2, which shows a bottom view of the liquid distribution unit in one embodiment of the present application. The drain holes 414 provided on the liquid distribution unit 40 in the present application are polygonal with sharp corners. Compared with the circular holes in the prior art, this can effectively reduce the occurrence of liquid sealing in the drain holes 414, allowing the water in the mounting groove 41 to flow out smoothly through each drain hole 414, ensuring that the water in the liquid distribution unit 40 can flow evenly and smoothly into the wet curtain 60, effectively preventing the wet curtain 60 from being unevenly wetted, thereby ensuring a good humidification effect and improving the user experience of the humidifier equipped with the wet curtain assembly 100.

[0047] In some embodiments, based on the aforementioned wet curtain assembly, the inner diameter of the drain hole 414 is not less than 2.5 mm, thereby further reducing the liquid sealing phenomenon of the drain hole 414, so that the water in the installation groove 41 can flow out smoothly through each drain hole 414.

[0048] In some embodiments, based on the aforementioned wet curtain assembly, the drain holes 414 are rectangular. It is understood that the shape of the drain holes 414 is not limited thereto. In other embodiments, the drain holes 414 may be regular or irregular shapes, such as squares, pentagons, or hexagons. It is understood that the shapes and sizes of the drain holes 414 may be the same or different. Depending on the location of the drain holes 414 and the required water discharge speed, the drain holes 414 at different locations may be configured with different shapes and sizes to meet different needs and achieve better infiltration effects.

[0049] In some embodiments, based on the aforementioned wet curtain assembly, all drain holes 414 are spaced apart along the second direction, with the spacing d between adjacent drain holes 414 ranging from 4 mm to 11 mm. Specifically, if the spacing between adjacent drain holes 414 is too large, certain locations of the wet curtain 60 corresponding to the locations between the two drain holes 414 may not be wetted. If the spacing between adjacent drain holes 414 is too small, the water flow into the wet curtain 60 may be excessive, leading to wasted power and water flow to the water pump, which in turn leads to negative effects such as increased costs and wasted resources. Therefore, setting the spacing d between adjacent drain holes 414 to 4 mm to 11 mm ensures uniform wetting of all locations on the wet curtain 60 while effectively reducing resource waste and lowering the cost of using the humidifier.

[0050] It is understood that the arrangement of the drain holes 414 is not limited and can be adjusted based on factors such as the shape of the mounting slot 41 and the configuration of other components to meet the liquid distribution requirements in different situations. Specifically, in one embodiment, the liquid distribution unit 40 is provided with three groups of drain holes 414. The three groups of drain holes 414 are arranged sequentially along the second direction, and the middle group of drain holes 414 is staggered with the other two groups of drain holes 414 in the third direction to avoid other structures.

[0051] During the research process, the applicant found that when the wet curtain 60 is inserted into the installation cavity from the insertion port along the second direction, since the height of the installation cavity in the first direction is almost the same as the height of the wet curtain 60 in the first direction, the wet curtain 60 is easily interfered with by the liquid distribution unit 40 and cannot be smoothly inserted into the installation cavity.

[0052] To address the above issues, based on the previously described wet curtain assembly, the present invention features a guide rib 416 protruding from the surface of the liquid distribution unit 40 facing the wet curtain 60. One end of the guide rib 416 connects to the edge of the drain hole 414 closest to the insertion port, while the other end of the guide rib 416 extends in a second direction toward the insertion port. In this way, the liquid distribution unit 40, through the guide rib 416 extending in the second direction, contacts the wet curtain 60, guiding it and allowing it to be smoothly assembled into the accommodating cavity.

[0053] In some embodiments, a guide edge is provided on one side of the liquid distribution unit 40 facing the wet curtain 60, surrounding each drain hole 414. Water flowing out of the drain hole 414 is guided by the guide edge into the wet curtain 60. However, when the wet curtain 60 is inserted into the mounting cavity from the insertion opening in the second direction, the wet curtain 60 may get stuck in the gap between two adjacent guide edges due to the presence of the protruding guide edge.

[0054] Therefore, the liquid distribution unit 40 in the present application is provided with a limiting rib 418 on the side surface facing the wet curtain 60, each limiting rib 418 is connected between the guide edges of two adjacent drain holes 414, and each limiting rib 418 extends along the second direction, thereby preventing the wet curtain 60 from being interfered with by the protruding guide edge during the insertion process into the installation cavity, so that the wet curtain 60 can enter the installation cavity more smoothly.

[0055] In a preferred embodiment, the height at which the guide edge projects from the surface of the liquid distributing unit 40 is slightly higher than the height at which the guide ribs 416 and the limiting ribs 418 project from the surface of the liquid distributing unit 40. This ensures that the guide edge provides guidance and prevents interference without affecting the guiding function of the guide edge. In other embodiments, the guide edge may also be flush with the guide ribs 416 and the limiting ribs 418.

[0056] 3 , 4 and 5 , FIG3 shows a side view of a wet curtain in an embodiment of the present application, FIG4 shows a top view of a wet curtain in an embodiment of the present application, and FIG5 shows a front view of a wet curtain in an embodiment of the present application.

[0057] In some embodiments, the wet curtain 60 includes a wet curtain body 61, which is a rectangular stacked structure formed by folding fiber paper. The wet curtain body 61 obtained by folding the fiber paper includes multiple laminates, all of which are connected end to end in sequence along the second direction, and folds extending along the first direction are formed between adjacent laminates. The spacing (i.e., the folding distance) L between two adjacent laminates is 3mm-5mm.

[0058] When the overall length of the wet curtain body 61 in the first direction is the same, if the maximum distance between two adjacent laminates is too large or too small, it will affect the humidification amount of the humidifier. The distance L between two adjacent laminates of the laminate of the present application is 3mm-5mm, which can make the humidification amount of the humidifier within the optimal range.

[0059] In some embodiments, compared to using non-woven fabrics and other materials to form the wet curtain body 61, the wet curtain body 61 in the present application is formed of fiber paper. Compared with non-woven fabrics and other materials, fiber paper has the characteristics of lighter weight, lower price, and faster drying speed. It is not easy to breed bacteria after long-term use, thereby alleviating the problem of mold and odor of the wet curtain body 61 to a certain extent and extending the service life of the wet curtain 60.

[0060] In some embodiments, each laminate is provided with a plurality of spaced-apart hydroentanglement holes 612, each of which has a diameter of 1.5 mm to 2 mm and is substantially circular. The airflow generated by the air duct assembly can pass through the hydroentanglement holes 612 and into the wet curtain 60. Conversely, if the diameter of the hydroentanglement holes 612 is too small, a liquid seal may easily form, blocking the airflow. If the diameter of the hydroentanglement holes 612 is too large, the effective evaporation area of ​​the wet curtain body 61 may be too small, affecting the evaporation efficiency of the water and, in turn, the humidification effect of the humidifier.

[0061] In some embodiments, the wet curtain 60 further includes at least two fixing ribs 63 formed on the wet curtain body 61. All fixing ribs 63 are spaced apart along a first direction, and each fixing rib 63 extends from one side of the wet curtain body 61 to the other side along a second direction, thereby maintaining a fixed spacing and supporting the shape of the wet curtain body 61. Specifically, in some embodiments, the fixing ribs 63 are formed by applying glue to the surface of the wet curtain body 61.

[0062] In some embodiments, the spacing H between two adjacent fixed ribs 63 is 25.4 mm or 50.8 mm, preferably 25.4 mm. In existing cognition, since the fixed ribs 63 are formed on the surface of the wet curtain body 61, they will hinder the flow of water on the wet curtain body 61. Therefore, the fewer the number of fixed ribs 63 on the wet curtain 60, the larger the water absorption area and wind passing area of ​​the wet curtain 60, thereby increasing the humidification capacity of the wet curtain 60. However, the applicant found in the course of research that appropriately increasing the number of fixed ribs 63 can make the wet curtain body 61 more firmly fixed, the folding distance between the laminates more uniform, and the overall humidification capacity of the wet curtain 60 is increased. Therefore, the spacing H between two adjacent fixed ribs 63 is 25.4 mm or 50.8 mm, which is different from the prior art in which the spacing between two adjacent fixed ribs 63 is 101.6 mm.

[0063] In some embodiments, the wet curtain 60 also includes an inlet water end piece and a outlet water end piece (not shown), which are respectively fixed to the upper and lower ends of the wet curtain body 61 in the first direction. The inlet water end piece and the outlet water end piece are both made of absorbent material (such as needle-punched cotton) and have excellent water absorption capacity.

[0064] In this way, water flowing out of the drain hole 414 is first absorbed by the inlet end piece and then transferred to the cooling pad body 61. After fully wetting the cooling pad body 61, the water that reaches the outlet end piece is absorbed and discharged by the outlet end piece. With the buffering effect of the inlet end piece, the water in the fabric is more stably and evenly transferred to the entire cooling pad body 61, effectively preventing concentrated and unstable water flow that could lead to excessive water flow or short-term excessive water accumulation. Furthermore, after wetting the cooling pad body 61, excess water is absorbed and discharged by the outlet end piece, thus preventing water accumulation and splashing.

[0065] In other embodiments, based on the good wetting performance of the wet curtain body 61 formed by fiber paper, the wet curtain 60 may not be provided with water supply end pieces and water discharge end pieces. The wet curtain body 61 is in direct contact with the liquid distribution unit 40, and the water flowing out of the drain hole 414 can directly enter the wet curtain body 61, thereby simplifying the structure of the wet curtain 60, further reducing the production cost of the wet curtain 60, and at the same time, it is not easy to mold and stink.

[0066] In the wet curtain assembly 100 and the humidifier equipped therewith, water in the liquid distribution unit 40 flows into the wet curtain 60 through the specially designed drain holes 414. Combined with the diameter and folding distance of the water-piercing holes 612 in the wet curtain body 61, as well as the spacing of the fixing ribs 63, the wet curtain 60 is fully moistened, effectively increasing the humidification rate. Furthermore, the provision of guide ribs 416 and retaining ribs 418 facilitates smooth installation of the wet curtain 60. Furthermore, the wet curtain body 61 formed of fiber paper significantly reduces costs while effectively alleviating the problem of mold and odor caused by prolonged moisture, ultimately improving the user experience of the humidifier.

[0067] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
