Description

Technical Field

[0001] This invention relates to the field of humidifier technology, specifically to an evaporative humidifier and its evaporative curtain fins and structure. Background Technology

[0002] Existing evaporative humidifiers include a wet curtain structure, which consists of a frame and multiple fins arranged in a straight line in the frame's vents. The fins are flat and arranged in a continuous, zigzag pattern to increase the water absorption area and completely block the frame's vents to improve humidification.

[0003] To improve water absorption, fins are generally made of hydrophilic materials such as spunlace nonwoven fabric and filter cotton to form a porous and breathable mesh structure. However, the fins cannot dry quickly after absorbing water, and prolonged water accumulation can easily lead to mold growth. Moreover, once moldy, it is difficult to clean and can only be replaced, resulting in a short service life and high operating costs. Summary of the Invention

[0004] To address the problems of easy mold growth, difficulty in cleaning, and high cost associated with humidifier condenser curtains, the primary objective of this invention is to provide a fin that can be easily dried by rotating to change its working state, enabling rapid drying, preventing mold growth, and increasing durability.

[0005] The second objective of this invention is to provide a mildew-resistant and durable humidifier curtain structure.

[0006] A third objective of this invention is to provide a mold-resistant and durable humidifier.

[0007] The wet curtain fins provided by the first objective of the present invention are provided with a group of holes that penetrate both sides of their thickness; in their extension direction, the first end is provided with a rotating connection structure located at the center of rotation.

[0008] As can be seen from the above scheme, with this configuration, the evaporative cooling pad fins can be rotatably installed onto the evaporative cooling pad frame. When the humidifier is running, water flows down from the drain holes at the top along the surface of the fins. The fins are arranged in a serrated pattern, restricting airflow to pass only through the pores of the fins, carrying water molecules out, thus achieving the humidification function. When humidification is not needed, the fins can be rotated to a parallel state to create a larger airflow channel, improving air circulation inside the evaporative cooling pad, quickly drying the fins, preventing water accumulation and mold growth, making it more durable and safer, and reducing operating costs.

[0009] A further option is to use a rotating connection structure as a rotating shaft or a shaft hole.

[0010] As can be seen from the above, this setting makes it easy for the wet curtain fins to swing.

[0011] A further proposed solution is to use plastic containing silver ions to make the evaporative cooling pad fins.

[0012] As can be seen from the above, in the working mode of the variable working state wet curtain structure of the present invention, ventilation and humidification are achieved by using the holes on the wet curtain fins, rather than by using the capillary porous breathable mesh structure of the fins themselves. Therefore, choosing plastic as the base material of the wet curtain fins can avoid the problem of water absorption, difficulty in drying and mold growth, while the fins as a whole are made of ABS material containing silver ions to ensure their antibacterial properties.

[0013] A further option is to provide a push connection structure at a position spaced apart from the rotation axis.

[0014] A further approach is to push the connection structure to include mounting ports that extend through both sides of the thickness of the wet curtain fins.

[0015] As can be seen from the above, the push connection structure is used to cooperate with the drive structure so that the wet curtain fins can be rotated by electronic control. The preferred solution is that the push connection structure includes an installation port, which, together with the push rod and multiple grooves on the push rod, can drive multiple wet curtain fins to rotate synchronously.

[0016] The second objective of this invention is to provide a wet curtain structure comprising a frame and fins mounted on the frame; at least one fin is a wet curtain fin as described above; the wet curtain fins are rotatably mounted in the frame along a rotation axis via a rotatable connection structure, and the wet curtain fins are rotatable between a first position and a second position; at least one side of the wet curtain fin in the first position forms an airflow channel, and the wet curtain fin in the second position blocks the airflow channel.

[0017] As can be seen from the above scheme, when the humidifier is running, water flows down from the drain hole at the top along the surface of the fins. The fins are arranged in a serrated pattern, closely adjacent to each other, restricting airflow to pass only through the fin holes, carrying water molecules out, thus achieving the humidification function. When humidification is not needed, the fins can be rotated to a parallel state to create a larger airflow channel, improving air circulation inside the evaporative cooling pad, quickly drying the fins, preventing water accumulation and mold growth, making it more durable and safer, and reducing operating costs.

[0018] A further embodiment is that multiple fins are arranged linearly; the multiple fins include a second fin disposed adjacent to the wet curtain fin, and the second fin is provided with a group of holes penetrating both sides of its thickness; an airflow channel is formed between the wet curtain fin in the first position and the second fin, and the wet curtain fin in the second position is adjacent to the second fin to block the airflow channel.

[0019] A further approach is that, in the arrangement direction of the multiple fins, two second fins are located on opposite sides of the wet curtain fin, and two airflow channels are formed between the two second fins and the wet curtain fin in the first position. The wet curtain fin in the second position is adjacent to the two second fins to block the two airflow channels respectively.

[0020] A further approach involves arranging multiple wet curtain fins and multiple second fins in an alternating pattern.

[0021] As can be seen from the above, assuming that all fins on the evaporative cooling pad are movable, in reality, to open or close the airflow channel by rotating the fins, adjacent fins must rotate in opposite directions. This setup presents significant design and control challenges, as well as high production costs. To optimize the structural design, reduce production costs, and simplify control, one could consider setting adjacent fins on one or even both sides of the evaporative cooling pad as fixed fins, i.e., the second fins of this invention. These second fins are installed along the ventilation direction, which reduces the number of movable evaporative cooling pad fins required. An even better solution is to set only one or more of the fins as movable evaporative cooling pad fins when staggered with multiple evaporative cooling pad fins and second evaporative cooling pads. Furthermore, these fins rotate in the same direction, making them easy to control and rotate synchronously. Unexpectedly, this setup also increases the fin arrangement density and total fin area, thus improving the humidification effect.

[0022] A further solution is to have a slot on the frame, and the second fin is slidably and detachably mounted on the slot.

[0023] As can be seen from the above, with this setup, the second fin can be easily disassembled, cleaned, and replaced.

[0024] A further option is to use a plastic containing silver ions for the second fin.

[0025] As can be seen from the above, using plastic as the base material for the second fin can avoid the problems of water absorption, difficulty in drying, and mold growth, while the fin as a whole uses ABS material containing silver ions to ensure its antibacterial properties.

[0026] Another further embodiment is that the frame includes a sidewall, and when a wet curtain fin adjacent to the sidewall is in a first position, an airflow channel is formed between the wet curtain fin and the sidewall, and when the wet curtain fin is in a second position, it is adjacent to the sidewall and blocks the airflow channel.

[0027] As can be seen from the above, with the help of the side wall of the frame, an airflow channel is formed to ensure that both sides of the outermost wet curtain fin are dried.

[0028] Another further option is that the evaporative cooling pad structure also includes a push rod with a groove; the evaporative cooling pad fins are provided with mounting openings that penetrate both sides of the thickness of the evaporative cooling pad fins at a position spaced apart from the rotation axis; the push rod passes through the mounting openings, the evaporative cooling pad fins cooperate with the grooves, and the evaporative cooling pad fins can be rotated when the push rod moves.

[0029] As can be seen from the above, this setting effectively achieves electronic control of the rotation of the wet curtain fins.

[0030] A further proposed solution includes at least two linearly arranged evaporative cooling pads; a push rod passes through multiple evaporative cooling pads, and multiple grooves engage with multiple evaporative cooling pads respectively; when the push rod moves, it can drive multiple evaporative cooling pads to rotate synchronously.

[0031] As can be seen from the above, a better solution is to use a single push rod to drive all the evaporative cooling pads to rotate synchronously. This method is simple and effective to control and ensures the synchronization of multiple evaporative cooling pads, thus guaranteeing the humidification effect in the first state and the drying effect in the second state.

[0032] The humidifier provided by the third objective of this invention includes the above-described wet curtain structure. Attached Figure Description

[0045] First embodiment of wet curtain structure

[0046] See Figures 1 to 3 The evaporative humidifier of the present invention includes a wet curtain structure. In this embodiment, the wet curtain structure includes a first fin 1, a second fin 2, a frame 3, and a push rod 34. The first fin 1 is the wet curtain fin of the present invention, and the first fin 1 is rotatably installed in the frame 3. The second fin 2 is detachably installed in the frame 3 in a sliding manner, and its position is fixed after installation. The push rod 34 is installed on the frame 3 and located below the top wall 31 of the frame 3. The push rod 34 is used to drive all the first fins 1 to rotate synchronously.

[0047] See Figure 1 The first fin 1 is a rectangular plate made of ABS plastic containing silver ions, and its length direction is the extension direction of the wet curtain fin of the present invention. The first fin 1 is provided with a rectangular array of holes 11, which penetrates between the two sides of the thickness of the first fin 1. The hole group 11 includes multiple micropores for airflow.

[0048] See also Figure 1 The length direction of the first fin 1, i.e. Figure 1 In the vertical direction shown, the first end of the first fin 1, i.e. Figure 1 The bottom of the first fin 1 shown is provided with a rotating shaft 12 extending from the first edge. The rotating shaft 12 is located at the rotation axis L. In addition, the rotating shaft 12 is in the center position in the width direction of the first fin 1. That is, the two sides of the first fin 11 in the width direction are the first edge 108 and the second edge 109, respectively. The distance from the rotating shaft 12 to the first edge 108 is equal to the distance from the rotating shaft 12 to the second edge 109.

[0049] See also Figure 1 In the length direction of the first fin 1, the second end opposite to the first end, i.e. Figure 1 The top of the first fin 1 shown has a mounting port 13 with an arc-shaped inner contour. The mounting port 13 is used to cooperate with the push rod 34. In addition, in the width direction of the first fin 1, the mounting port 13 is spaced from the rotation axis L. The purpose of this arrangement is to form a lever arm between the position of the mounting port 13 and the rotation axis L.

[0050] See Figure 2The second fin 2 is a rectangular plate made of ABS plastic containing silver ions, and its length direction is the extending direction of the wet curtain fin of the present invention. A rectangular array of holes 21 is provided on the second fin 2, the hole array 21 extending between the two sides of the thickness of the second fin 2. The hole array 21 includes multiple micropores for airflow. At one end of the second fin 2 along its length direction, i.e. Figure 1 The second fin 2 shown has a clearance opening 23 at its top. The inner contour of the clearance opening 23 is square. The clearance opening 23 is used to avoid the push rod 34.

[0051] See Figure 3 The frame 3 is a rectangular frame, which includes a top wall 31 at the top, two side walls 32 on the left and right sides, and a bottom wall 33 at the bottom. The top wall 31, the two side walls 32, and the bottom wall 33 surround to form a ventilation opening 300. Figure 1 and Figure 2 The multiple first fins 1 and multiple second fins 2 shown are all disposed in the ventilation opening 300.

[0052] Combined Figure 4 The top view of the frame 3 shown shows that the top wall 31 is a permeable plate with a group of water holes 310 on it, which allows water to flow from the top of the frame 3 down into the vent 300.

[0053] Combined Figure 6 Multiple first slots 312 are provided on the lower surface of the top wall 31. The multiple first slots 312 are arranged alternately along the length direction of the top wall 31, which is perpendicular to the opening direction of the vent 300. The first slots 312 are formed between two protrusions, and the extension direction of the first slots 312 is the opening direction of the vent 300.

[0054] See Figure 4 The top view of the bottom wall 33 shown and Figure 7 The upper surface of the bottom wall 33 is provided with multiple shaft holes 331 and multiple second slots 332. The multiple second slots 332 and the multiple shaft holes 331 are staggered along the length direction of the bottom wall 33, which is perpendicular to the opening direction of the vent 300. The second slots 332 are formed between two protruding strips, and their extension direction is the opening direction of the vent 300. The second slots 332 on the bottom plate 33 and the first slots 312 on the top plate 31 are arranged opposite each other along the height direction of the frame 3 and their openings are opposite to each other. The second fin 2 can be slidably and detachably installed between the first slots 312 and the second slots 332. Both the first slot 312 and the second slot 332 are slots of this invention.

[0055] See Figure 3 and Figure 6The push rod 34 passes through the two side walls 32 and is slidably mounted directly below the top wall 31 along its length. The push rod 34 is provided with a plurality of grooves 341 arranged at intervals along its extension direction, and the grooves 341 are annular grooves surrounding the push rod 34.

[0056] Combined Figure 8 Multiple first fins 1 and multiple second fins 2 are arranged alternately along the length of the frame 3, and the water flow on the top wall 31 can fall onto the surfaces of the multiple first fins 1 and multiple second fins 2. The installation method of the second fins 2 has been described above and will not be repeated. The rotating shaft 12 of the first fin 1 is inserted into the shaft hole 331 of the bottom wall 33 to realize the rotational connection of the first fin 1. In addition, the push rod 34 passes through the mounting holes 13 of all the first fins 1 and the clearance holes 23 of all the second fins 2. The part of the first fin 1 surrounding the mounting hole 13 is exactly located in the groove 341 on the push rod 34. Thus, when the push rod 34 moves in a straight line, the first fin 1 can be driven to swing.

[0057] It is important to note that, since the first fin 1 swings after being pushed, the groove width of the groove 341 is greater than the thickness of the first fin 1 to avoid interference and jamming during operation. Furthermore, in the opening direction of the vent 300, the distance between the push rod 34 and the first axis L is fixed, while the distance between the mounting port 13 and the first axis L changes as the first fin 1 swings. Therefore, to avoid interference and jamming during operation, it is preferable that, in the horizontal direction, the size of the mounting port 13 is larger than the size of the push rod 34.

[0058] See Figure 8 , Figure 8 The illustrated evaporative cooling pad structure is in a drying operation state. At this time, multiple first fins 1 are in the first position, and the multiple first fins 1 and multiple second fins 2 are parallel to each other. Among the multiple fins, those adjacent to the side walls 32 on both sides are rotatable first fins 1. In this state, an airflow channel 301 is formed between any first fin 1 and its adjacent second fins 2 or its adjacent side wall 32. In this state, airflow can pass through these airflow channels 301 and through the vent 300, and the airflow can quickly dry the moisture on the surfaces of the first fins 1 and second fins 2, preventing water accumulation and mold growth, making it more durable and safer, and reducing operating costs.

[0059] Combined Figure 9 , Figure 9 The evaporative cooling pad structure shown is in humidification mode. Multiple first fins 1 have already rotated synchronously under the push of push rod 34 and can then... Figure 8 The first position shown is rotated to Figure 9 The second position shown indicates that the first fin 1 is tilted relative to the second fin 2. Specifically, in the two outermost first fins 1, Figure 9The first edge 108 of the leftmost first fin 1 shown is adjacent to the left sidewall 32, while the second edge 109 is adjacent to a second fin 2. Figure 9 The first edge 108 of the rightmost first fin 1 is adjacent to the second fin 2, and the second edge 109 is adjacent to the right sidewall 32. The first edges 108 and second edges 109 of the remaining first fins 1 are adjacent to two adjacent second fins 2 respectively. At this time, the two sidewalls 32, the multiple first fins 1 and the multiple second fins 2 are connected to form a serrated barrier. All airflow channels 301 are blocked by the rotated first fins 1. At this time, the airflow can only pass through the hole group 11 on the first fin 1 and the hole group 21 on the second fin 2, so that the moisture on the surface of the first fins 1 and the second fins 2 can be carried out, producing a good humidification effect.

[0060] Second embodiment of the wet curtain structure

[0061] See Figure 10 and Figure 11 In other embodiments, three first fins 411 and three second fins 412 are arranged in a staggered straight line, and both the first fins 411 and the second fins 412 are rotatable wet curtain fins of the present invention. Additionally, this embodiment requires a first push rod 421 and a second push rod 422. The first push rod 421 is used to drive the first fin 411 in the first position to deflect to the left, while the second push rod 422 is used to drive the second fin 412 in the first position to deflect to the right. See also... Figure 11 When all the first fins 411 and all the second fins 412 reach the second position, a serrated barrier is formed between the multiple first fins 411 and the multiple second fins 412.

[0062] See Figure 12 Compared with the first embodiment and the second embodiment, in the same length of wet curtain structure, the first embodiment can actually set more fins to achieve a better humidification effect.

[0063] In other embodiments, the pivot may be located in a non-central position on the first fin, but this setting requires adjustment of the first fin and the first fins or sidewalls on its left and right sides.

[0064] In other embodiments, a shaft hole is provided on the first fin, and a rotating shaft is provided on the frame.

[0065] In other embodiments, a linkage mechanism is provided on the wet curtain structure, and the first fin is driven by the linkage mechanism. Correspondingly, the push connection structure can be a hinge structure or a ball joint structure that cooperates with the linkage mechanism.

[0066] In other embodiments, the first fin and / or the second fin are plates made of metal, such as aluminum plates.

[0067] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
