In some areas with high environmental humidity, special dehumidification equipment is required to perform dehumidification, such as an air conditioner with a dehumidification function. When high-humidity air passes through an air duct in the air conditioner, water vapor can be condensed on the wall surface of the inner wall of the air duct, part of condensed water flows down along the wall surface under the action of gravity, and part of the condensed water directly drips in the vertical direction.
Referring to fig. 1 to 3, a flow guiding structure 1 according to an embodiment of the present invention is configured to be disposed in a housing 100. The diversion structure 1 comprises an air-permeable water-retaining layer 11, and a gap 13 is formed between the air-permeable water-retaining layer 11 and the inner wall of the casing 100, so that condensed water flows along the gap 13.
According to the diversion structure 1 of the embodiment of the invention, the air-permeable water-retaining layer 11 is arranged in the inner wall of the shell 100, and the gap 13 is formed between the air-permeable water-retaining layer 11 and the inner wall of the shell 100, so that when air passes through the space in the shell 100, moisture in the air is condensed on the inner wall of the shell 100 through the air-permeable water-retaining layer 11 to form condensed water, and the condensed water can only flow down along the inner wall surface of the shell 100 or from the gap 13 under the action of gravity and repulsive force (namely surface tension) of the air-permeable water-retaining layer 11, so that the water guiding speed of the inner wall of the shell 100 is improved, the dehumidification of the dehumidification equipment is promoted, and the problems that the condensed water is accumulated to cause mildew or bacteria breeding, and the condensed water.
Some existing housings 100 are made of hydrophilic materials, which have good water-conducting performance, and some housings 100 are made of materials, which have poor water-conducting performance. Therefore, in order to ensure that the water guiding structure 1 has a good water guiding effect when applied to the casing 100, the water guiding structure 1 of the embodiment of the present invention further includes a hydrophilic layer 12, and the hydrophilic layer 12 is attached to the inner wall of the casing 100, that is, the hydrophilic layer 12 is located between the inner wall of the casing 100 and the air-permeable and water-retaining layer 11, and has a certain gap 13 with the air-permeable and water-retaining layer 11. The hydrophilic layer 12 can be coated or adhered on the inner wall of the casing 100, and after the gas contacts with the casing, the water vapor therein is easily combined with the gas to form a water film quickly and flows down quickly under the action of gravity, so that the water guiding speed of the inner wall of the casing 100 is increased, and the dehumidifying capacity of the dehumidifying equipment (such as an air conditioner) applying the flow guiding structure is improved.
In general, the size of the gap 13 between the gas-permeable water-retaining layer 11 and the hydrophilic layer 12 is related to the contact angle between the hydrophilic layer 12 and the gas-permeable water-retaining layer 11, and the smaller the contact angle of the hydrophilic layer 12 is, or the larger the contact angle of the hydrophobic layer is, the smaller the gap 13 may be. Considering that the gap 13 between the air-permeable water retaining layer 11 and the hydrophilic layer 12 cannot be too large, otherwise the air-permeable water retaining layer 11 cannot provide an effective repulsion force for the condensed water on the hydrophilic layer 12; if the gap 13 between the water-permeable barrier layer 11 and the hydrophilic layer 12 is too small, the water-permeable barrier layer 11 will be immersed in the condensed water layer on the hydrophilic layer 12 to block the flow of the condensed water. Therefore, the gap 13 between the hydrophilic layer 12 and the air-permeable and water-retaining layer 11 in the embodiment of the present invention is preferably 2-10 mm.
Accordingly, the diameter of the meshes of the breathable water retaining layer 11 cannot be too large, otherwise, condensed water is easy to drop from the meshes; the mesh diameter of the air-permeable water retaining layer 11 cannot be too small, otherwise the air resistance is too large. Therefore, in the embodiment of the present invention, the mesh number of the air-permeable water-blocking layer 11 is preferably 30-80 meshes.
The air-permeable water retaining layer 11 needs to have a large surface tension to the condensed water to act on the condensed water and provide an effective force. Therefore, preferably, the air-permeable water-blocking layer 11 is made of a hydrophobic material, or the air-permeable water-blocking layer 11 includes a mesh layer body on which a hydrophobic layer is coated, and the hydrophobic layer can be made of a hydrophobic material.
In particular, the hydrophobic material may be a fluorine-containing polymer, such as polytetrafluoroethylene, polyvinylidene fluoride, or hydrophobic TiO2Or hydrophobic SiO2The materials have the advantages of good hydrophobic property, electrical insulation, high temperature resistance and the like.
Alternatively, the breathable water-retaining layer 11 can be made of polytetrafluoroethylene or polyvinylidene fluoride only; or the net layer body in the breathable water retaining layer 11 is made of plastic, stainless steel or copper, and then a hydrophobic layer is formed on the net layer body in a spraying, depositing or soaking mode and the like, wherein the hydrophobic layer can be polytetrafluoroethylene, polyvinylidene fluoride or hydrophobic TiO2Or hydrophobic SiO2. The two schemes for manufacturing the breathable water retaining layer 11 have good hydrophobic property and are easy to mold and process.
The hydrophilic layer 12 can be a high molecular polymer film made of a material containing polar hydrophilic groups, such as-COOH (carboxyl), -SO3H (sulfonic group), -OH (hydroxyl group), etc., silicon-based nano hydrophilic materials with contact angle less than 10 degrees, such as hydrophilic SiO, can also be used as surface coating2Hydrophilic TiO may also be used2As a surface coating. Specifically, a material containing a polar hydrophilic group such as sulfonated polyarylether (containing a sulfonic acid group), polyvinyl alcohol, cellulose acetate butyrate (containing a hydroxyl group), polyimide acid, or a carboxyl modified material (containing a carboxyl group) is easily filmed and can be adhered to the inner wall of the housing; for hydrophilic TiO2Or hydrophilic SiO2Can be directly sprayed on the inner wall of the shell.
In addition, the embodiment of the invention also comprises a composite material which comprises a breathable water retaining layer 11 and a hydrophilic layer 12, wherein a gap 13 is arranged between the breathable water retaining layer 11 and the hydrophilic layer 12. The structure and material of the breathable water-retaining layer 11 and the hydrophilic layer 12 are the same as those of the breathable water-retaining layer 11 and the hydrophilic layer 12 in the diversion structure 1 described in the above embodiment, respectively, and the same technical effects can be obtained, which are not described herein again.
The embodiment of the present invention further includes a dehumidification device, which includes a housing, wherein an air duct is disposed in the housing, the air duct is enclosed by a housing 100, and the air duct is disposed with the diversion structure 1 in the foregoing embodiment, as shown in fig. 4. Since the flow guide structure installed in the dehumidification device of the present embodiment is the same as the structure provided in each of the embodiments of the flow guide structure described above, both can solve the same technical problem and achieve the same intended effect. Specifically, the edge of the breathable water-retaining layer 11 in the diversion structure can be bent towards one side of the shell, and an adhesive strip is arranged to fix the breathable water-retaining layer 11 on the inner wall of the air duct or the hydrophilic layer.
In order to solve the problem of discharging the condensed water, in the air duct of the embodiment of the present invention, a drainage outlet 200 is provided, a tip flow guiding portion 101 is provided at a side of the flow guiding structure 1 close to the drainage outlet 200, and the tip flow guiding portion 101 is connected to the drainage outlet 200, as shown in fig. 5 (an arrow in the figure indicates a flow direction of the condensed water), which can promote the condensed water to converge and accelerate the drainage of the condensed water from the drainage outlet 200. The dehumidifying equipment can be a dehumidifier, or an air conditioner and air purifier with dehumidifying function, etc.
