In the description of the present invention, "a plurality" means two or more.
The dehumidifier 1 according to the embodiment of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 1 to 14, the dehumidifier 1 includes a case 100, an evaporator 200, a condenser 300, an auxiliary water condenser 400, and a fan 500.
The casing 100 has a first air path and a second air path, the dotted arrow in the drawing indicates the first air path, the solid arrow indicates the second air path, the evaporator 200 is installed in the casing 100, the condenser 300 is installed in the casing 100, the auxiliary water condenser 400 is installed in the casing 100 and located between the evaporator 200 and the condenser 300, the auxiliary water condenser 400 includes a plurality of auxiliary air ducts 410, the first air path sequentially passes through the evaporator 200, the outer surfaces of the plurality of auxiliary air ducts 410 and the condenser 300, the second air path sequentially passes through the interiors of the plurality of auxiliary air ducts 410 and the condenser 300, and the fan 500 is installed in the casing 100 and is used for guiding the air of the casing 100 to flow through the first air path and the second air path and then to be discharged. The fan 500 may be a centrifugal fan 500, and the size of the dehumidifier 1 in the axial direction of the fan 500 may be reduced.
For example, the auxiliary duct 410 is made of a material having a heat transfer coefficient higher than 150W/(m2 × K), such as polyvinylidene fluoride (PVDF) or copper metal. When the auxiliary air duct 410 is made of copper, the inner surface of the auxiliary air duct 410 may be coated with a fluoro-silane polymer to form a super-hydrophobic surface, so as to improve the surface condensation heat transfer coefficient of the auxiliary air duct 410, thereby promoting the condensation of moisture in the air. When the auxiliary air duct 410 is made of polyvinylidene fluoride, the wall of the auxiliary air duct 410 is less than 0.1mm, and the production cost can be effectively controlled because the polyvinylidene fluoride is cheap.
Also, the housing 100 may have an intake vent 110, an outtake vent 120, and a mounting opening. The air in the first air path may enter the casing 100 from the air inlet 110, and then flow out of the casing 100 from the air outlet 120. The auxiliary water condenser 400 is detachably mounted to the casing 100 through the mounting opening, each of the auxiliary air ducts 410 is communicated with the outside of the casing 100 through the mounting opening, and air in the second air path can enter the casing 100 through the plurality of auxiliary air ducts 410 and then flow out of the casing 100 through the air outlet 120.
According to the dehumidifier 1 of the embodiment of the present invention, the first air path and the second air path are provided in the casing 100, the evaporator 200, the condenser 300 and the auxiliary water condenser 400 are all installed in the casing 100, the auxiliary water condenser 400 is located between the evaporator 200 and the condenser 300, the auxiliary water condenser 400 includes the plurality of auxiliary air ducts 410, and the first air path sequentially passes through the evaporator 200, the outer surfaces of the plurality of auxiliary air ducts 410 and the condenser 300. The air in the first air path exchanges heat with the evaporator 200 to form low-temperature humid air at 15-18 ℃, the low-temperature humid air flows through the outer surface of the auxiliary air duct 410 to exchange heat with the air in the auxiliary air duct 410 (the air in the auxiliary air duct 410 comes from the second air path), and at the moment, the air in the auxiliary air duct 410 is cooled to separate out moisture, so that the low-temperature humid air passing through the evaporator 200 can be fully utilized, more air can be dehumidified while the energy consumption of the dehumidifier 1 is not increased, and the dehumidification capacity of the dehumidifier 1 is improved.
In addition, the second air path sequentially passes through the inside of the plurality of auxiliary air ducts 410 and the condenser 300, and since the heat exchange amount of the condenser 300 is the sum of the cooling capacity of the dehumidifier 1 and the heat generated by the work of the compressor of the dehumidifier 1, the heat exchange area of the condenser 300 should be larger than the heat exchange area of the evaporator 200, or the air volume flowing through the condenser 300 should be larger than the air volume flowing through the evaporator 200, or the heat exchange area of the condenser 300 should be larger than the heat exchange area of the evaporator 200 and the air volume flowing through the condenser 300 should be larger than the air volume flowing through the evaporator 200. Through setting up supplementary water condenser 400, supplementary tuber pipe 410 can distribute inside air, carries to condenser 400 again, utilizes the distribution of supplementary tuber pipe 410, and its inside air can be concentrated and carried to condenser 400, increases the effective amount of wind that flows through condenser 300, and then increases the heat transfer volume of condenser 300, and the heat transfer area of condenser 300 need not to increase to reduce the resistance that the gas of first wind path and second wind path flows, improve the performance of dehumidifier 1.
In addition, the condenser 300 can heat and dry the air in the first air passage and the second air passage, so that the temperature and the humidity of the air discharged from the dehumidifier 1 are more suitable for the human body, and the air outlet comfortableness of the dehumidifier 1 is improved.
Therefore, the dehumidifier 1 according to the embodiment of the invention can improve the heat exchange amount of the condenser 300, optimize the product performance, and has the advantages of high dehumidification amount and the like.
According to some embodiments of the present invention, as shown in fig. 1 and 14, the first and second air paths merge before passing through the condenser 300.
For example, the first duct and the second duct may be vertically disposed before being merged, and when the air in the second duct flows in the auxiliary duct 410, the air in the second duct exchanges heat with the air in the first duct, and at this time, the air in the second duct is cooled to precipitate moisture; when the air in the second duct flows out of the auxiliary duct 410, heat exchange with the air in the first duct is performed again, and at this time, the temperature of the air in the second duct is decreased again, and moisture is again precipitated from the air in the second duct. Therefore, the heat exchange time of the air in the first air path and the air in the second air path is greatly prolonged, the moisture of the air in the second air path is favorably reduced, and the mixed air is mixed and then passes through the condenser 300, so that the dehumidification amount of the dehumidifier 1 is further increased.
According to some embodiments of the present invention, as shown in fig. 3, 8 and 10, the plurality of auxiliary air ducts 410 includes at least one supply air duct 411 and at least one condensing air duct 412, a side of the supply air duct 411 facing the condenser 300 is provided with a plurality of supply air holes 413, and the plurality of supply air holes 413 are arranged at intervals, for example, at equal intervals, along a length direction of the supply air duct 411.
On one hand, the air supply duct 411 can uniformly supply air through the air supply holes 413, so that the air quantity and uniformity flowing through the condenser 300 are increased, the heat exchange quantity of the condenser 300 is improved, the phenomenon of uneven air quantity flowing through all parts of the condenser 300 can be improved, and the heat exchange effect of the condenser 300 is improved; on the other hand, moisture in the air supply duct 411 can be cooled and precipitated by the air in the first duct, thereby increasing the dehumidification capacity of the dehumidifier 1.
The air in the condensing duct 412 and the air in the second duct can exchange heat for a longer time, and the amount of dehumidification of the air flowing through the condensing duct 412 is higher, thereby further increasing the amount of dehumidification of the dehumidifier 1. The air flowing out from the blower duct 411 merges with the air in the first duct and flows through the condenser 300, thereby further increasing the air volume flowing through the condenser 300.
Specifically, the cross-sectional areas of the air supply holes 413 are gradually reduced along the air guiding direction of the second air path, so that the air outlet flow rates of the air supply holes 413 are approximately the same, and it is further ensured that the air outlet of the air supply duct 411 in the length direction is more uniform, so that the heat exchange efficiency between the air in the second air path and the air in the first air path is high, and the heat exchange between the air in the second air path and the whole condenser 300 is more uniform.
For example, the air outlet flow calculation formula of each air blowing hole 413 is as follows:
in the formula: l is the air outlet flow of the air outlet 413, and the unit is m3H; mu is an air outlet flow coefficient; f is the cross-sectional area of the blower hole 413 in m2(ii) a Δ p is the static pressure difference of the blowing hole 413 in Pa; ρ is the density of air flowing through the air supply hole and has a unit of kg/m3。
According to some embodiments of the present invention, as shown in fig. 2 to 4, the blowing air duct 411 and the condensing air duct 412 are respectively plural and arranged in a row between the evaporator 200 and the condenser 300, and the blowing air duct 411 and the condensing air duct 412 are alternately arranged at intervals in a direction perpendicular to the first air path and the second air path. Thus, the auxiliary water condenser 400 is simple in overall arrangement and convenient to process, and the installation space required in the thickness direction of the auxiliary water condenser 400 is small.
Alternatively, as shown in fig. 5-12, the plurality of blowing air pipes 411 are arranged in at least one row between the evaporator 200 and the condenser 300, the plurality of condensing air pipes 412 are arranged in at least one row between the evaporator 200 and the condenser 300, the auxiliary air pipes 410 in each row are arranged at intervals along a direction perpendicular to the first air path and the second air path, the auxiliary air pipes 410 in two adjacent rows are correspondingly arranged (as shown in fig. 5-8) or staggered (as shown in fig. 9-12), wherein the row of the blowing air pipes 411 is closer to the condenser 300 than the row of the condensing air pipes 412.
In this way, the arrangement of the plurality of auxiliary air pipes 410 of the auxiliary water condenser 400 is more compact, which is beneficial to increasing the number of the auxiliary air pipes 410, so as to further improve the dehumidification amount of the dehumidifier 1, and further increase the air volume flowing through the condenser 300, i.e. increase the heat exchange amount of the condenser 300, and optimize the performance of the dehumidifier 1. In addition, the blowing duct 411 is closer to the condenser 300 than the condensing duct 412, and the air in the blowing duct 411 can be directly blown to the condenser 300 through the blowing hole 413 without being interfered by the condensing duct 412.
Further, the length of the blowing duct 411 is smaller than that of the condensing duct 412. When the air supply pipes 411 and the condensing pipes 412 are arranged into multiple rows, the air supply pipes 411 can be prevented from blocking the air outlet of the condensing pipes 412, the air outlet smoothness of the condensing pipes 412 is improved, and the dehumidification capacity of the dehumidifier 1 and the heat exchange capacity of the condenser 300 are ensured.
According to some embodiments of the present invention, as shown in fig. 4, 7 and 11, the end surfaces of the ends of the air supply duct 411 and the air condensation duct 412 facing the same side are open, air outside the housing 110 can enter the air supply duct 411 and the air condensation duct 412 from the end, and the end surface of the other end of the air supply duct 411 is closed. Therefore, almost all the air in the air supply duct 411 is discharged from the air supply hole 413, so that the air discharged from the air supply duct 411 can be fully contacted with the condenser 300, the heat exchange quantity of the condenser 300 is improved, and the performance of the dehumidifier 1 is further optimized.
And, the bottom of the perisporium of the other end of the blast air pipe 411 is equipped with the hole of congealing 414, wherein, the distance of the hole of congealing 414 and the terminal surface of the said other end of blast air pipe 411 is 2mm ~ 8mm, and the terminal surface of the other end of the condensation tuber pipe 412 opens the setting. Therefore, the condensed water in the air supply duct 411 and the condensed air duct 412 can flow out conveniently, and the gas in the condensed air duct 412 can flow out through the other end of the condensed air duct 412.
According to some embodiments of the present invention, as shown in fig. 3, 8 and 10, the blowing duct 411 is disposed obliquely with respect to the horizontal direction, and the other end of the blowing duct 411 is lower than the one end of the blowing duct 411. The condensing duct 412 is disposed obliquely with respect to the horizontal direction, and the other end of the condensing duct 412 abuts against the one end of the blowing duct 411. The slope of each auxiliary air duct 410 may be set to 1% to 5%, that is, the ratio of the distance between the two ends of each auxiliary air duct 410 in the vertical direction to the distance between the two ends thereof in the horizontal direction is 1% to 5%. This facilitates smooth discharge of the condensed water in each of the auxiliary ducts 410.
According to some embodiments of the present invention, as shown in fig. 2, 5 and 9, an end surface of the other end of the condensing air pipe 412 is disposed obliquely with respect to an axial direction of the condensing air pipe 412 and faces the condenser 300, wherein an included angle between the end surface of the other end of the condensing air pipe 412 and the axial direction of the condensing air pipe 412 is 30 ° to 60 °, for example, 45 °. Therefore, the gas flowing out of the condensing air pipe 412 flows towards the direction of the condenser 300, so that the gas can contact with the condenser 300 as much as possible, the comfort of air outlet of the dehumidifier 1 is ensured, the heat exchange quantity of the condenser 300 is improved, and the performance of the dehumidifier 1 is further optimized.
According to some embodiments of the present invention, as shown in fig. 13, the cross-section of the auxiliary duct 410 is configured in an egg shape (which may also be understood as a drop shape without a sharp corner) and has a first circular arc portion 415 and a second circular arc portion 416, the first circular arc portion 415 is disposed toward the evaporator 200, the second circular arc portion 416 is disposed toward the condenser 300, and the diameter of the first circular arc portion 415 is greater than that of the second circular arc portion 416. In other words, the cross section of the auxiliary duct 410 is formed in a streamline shape that can reduce the air flow resistance of the first duct.
In this way, not only the flow resistance of the air in the first air passage on the surface of each auxiliary air duct 410 facing the evaporator 200 can be effectively reduced to reduce the power consumption of the fan 500, but also the possibility of forming a vortex on the side of each auxiliary air duct 410 facing away from the evaporator 200 can be reduced, and the air in the first air passage can be effectively and uniformly dispersed. In addition, the compactness of the arrangement of the plurality of auxiliary air ducts 410 can be improved, so that the occupied space of the auxiliary water condenser 400 is reduced.
According to some embodiments of the present invention, as shown in fig. 13, the cross-section of the auxiliary duct 410 has a first axis 417 and a second axis 418, the first axis 417 has two ends respectively intersecting with the center of the first circular arc portion 415 and the center of the second circular arc portion 416, and the second axis 418 is orthogonal to the first axis 417. The distance between the second shaft 418 and the center of the first circular arc part 415 is L1, the distance between the second shaft 418 and the center of the second circular arc part is L2, and the length of the second shaft 418 is generally L3, wherein L1/L3 is 1-2, and L2/L1 is 2-3. Thus, the air flow resistance of each auxiliary air duct 410 to the first air path is lower, and the possibility of the air of the first air path forming vortex is lower, thereby improving the working performance of the dehumidifier 1.
According to some embodiments of the present invention, as shown in fig. 2, 5 and 9, the auxiliary water condenser 400 further includes a first end plate 420 and a second end plate 430, the first end plate 420 is detachably mounted to the housing 100, the one end of each of the auxiliary air ducts 410 is penetrated through the first end plate 420 and the other end is penetrated through the second end plate 430. Both the first end plate 420 and the second end plate 430 may be made of ABS (Acrylonitrile Butadiene Styrene) material.
For example, the first end plate 420 is provided with a snap, and the housing 100 is provided with a snap groove, the snap and the snap groove cooperating. Alternatively, the first end plate 420 and the housing 100 are connected by a threaded fastener (screw or bolt). When the dehumidifier 1 stops operating, the auxiliary water condenser 400 may be drawn out from the casing 100 to be cleaned, dirt on the outer surface and the inner surface of the auxiliary water condenser 400 may be removed, and the auxiliary water condenser 400 may be installed in the casing 100 again.
Each of the condensed water holes 414 is located on a side of the second end plate 430, which is back to the first end plate 420, and a distance between an axis of each of the condensed water holes 414 and the second end plate 430 in the horizontal direction is 1cm to 2cm, so that the second end plate 430 can prevent the condensed water of the auxiliary air duct 410 from splashing in the dropping process, and the probability that the condensed water is blown to the condenser 300 by the air of the first air path when the condensed water splashes is reduced.
And, the distance between the end surface of each auxiliary air duct 410 close to the second end plate 430 and the casing 100 is greater than 1cm, so as to avoid interference between the auxiliary air duct 410 and the casing 100 and ensure the reliability of assembly between the auxiliary water condenser 400 and the casing 100.
So, through setting up first end plate 420 and second end plate 430, not only can fix the position of supplementary tuber pipe 410, and supplementary condenser 400's simple structure is favorable to reduction in production cost.
