[0013] Generally, a dehumidifier includes a housing, an evaporator, a condenser, and a liquid condenser. The liquid condenser is used to introduce indoor air, and the low-temperature gas that has passed through the evaporator exchanges heat with the indoor air in the liquid condenser, so that the water vapor in the indoor air can be condensed into condensed water, thereby realizing the dehumidification of the indoor air. However, due to the existence of a supercooling phenomenon in a part of the evaporator and the different flow rates of the gas that have passed through different parts of the evaporator, the low-temperature gas that has passed through the evaporator has different amounts of cooling at different positions of the liquid condenser, making it difficult for the liquid condenser to fully utilize the low-temperature gas, and the dehumidifier has a relatively low utilization rate of the amount of cooling of the low-temperature air, and the dehumidification efficiency of the dehumidifier is relatively low.

[0014] To solve the above problems, in some embodiments of the present disclosure, a dehumidifier 1 is provided.

[0015] FIG. 1 is a structural diagram of a dehumidifier according to some embodiments.

[0016] 1, the dehumidifier 1 includes a compressor 10, an evaporator 200, a condenser 300, and an expansion valve 40. The compressor 10, the condenser 300, the expansion valve 40, and the evaporator 200, which are connected in order, form a refrigerant circuit. The refrigerant circulates through the refrigerant circuit and exchanges heat with the air via the evaporator 200 and the condenser 300, respectively, to adjust the humidity and temperature of the surrounding environment.

[0017] The compressor 10 is configured to compress a refrigerant so that a low-pressure refrigerant becomes a high-pressure refrigerant by compressing the refrigerant. The refrigerant discharged from the compressor 10 flows into the condenser 300.

[0018] The condenser 300 is configured to exchange heat between the ambient air and the refrigerant transported within the condenser 300. The refrigerant compressed by the compressor 201 radiates heat to the ambient air through the condenser 300 and is condensed, and the condensed refrigerant is discharged from the condenser 300 to the expansion valve 40.

[0019] The expansion valve 40 is connected between the condenser 300 and the evaporator 200, and the pressure of the refrigerant flowing between the condenser 300 and the evaporator 200 is adjusted depending on the opening degree of the expansion valve 40, thereby adjusting the flow rate of the refrigerant flowing between the condenser 300 and the evaporator 200. The flow rate and pressure of the refrigerant flowing between the condenser 300 and the evaporator 200 affect the heat exchange performance between the condenser 300 and the evaporator 200. The opening degree of the expansion valve 40 is adjustable, thereby controlling the flow rate and pressure of the refrigerant flowing through the expansion valve 40. For example, the expansion valve 40 expands the liquid refrigerant condensed in the condenser 300 to a low-pressure liquid refrigerant, and the low-pressure liquid refrigerant is discharged from the expansion valve 40 to the evaporator 200.

[0020] The evaporator 200 is configured to exchange heat between the ambient air and the refrigerant transported within the evaporator 200. The refrigerant dissipated heat by the condenser 300 absorbs heat from the ambient air through the evaporator 200 and evaporates, and the evaporated refrigerant flows back to the compressor 10, thereby completing the circulation of the refrigerant.

[0021] In the process of refrigerant circulation, indoor air may be drawn into the dehumidifier 1 and pass through the evaporator 200 and the condenser 300 in order. When the drawn indoor air passes through the evaporator 200, moisture in the indoor air is condensed into condensed water on the surface of the evaporator 200. The dried indoor air exchanges heat with the condenser 300, and the indoor air absorbs heat and is discharged from the dehumidifier 1, thereby achieving dehumidification of the indoor air.

[0022] The dehumidifier 1 according to some embodiments of the present disclosure will be described in detail below.

[0023] Figure 2 is another structural view of a dehumidifier according to some embodiments. Figure 3 is an exploded view of a part of the structure of a dehumidifier according to some embodiments. Figure 4 is another exploded view of a part of the structure of a dehumidifier according to some embodiments.

[0024] 1 to 3, the dehumidifier 1 further includes a housing 100, a liquid condenser 400, and a fan 50. The evaporator 200, the condenser 300, the liquid condenser 400, and the fan 50 are each installed in the housing 100.

[0025] The housing 100 is provided with a first air passage 11 (shown in FIG. 7) and a second air passage 12 (shown in FIG. 8), and the first air passage 11 and the second air passage 12 respectively guide the indoor air entering the dehumidifier 1 so that the indoor air may flow through different components within the dehumidifier 1 along corresponding paths.

[0026] The evaporator 200 and the condenser 300 are arranged in sequence along a first direction. , and located in the first air duct 11 The first direction is parallel to a width direction of the dehumidifier 1 (for example, a front-to-rear direction in FIG. 2). For example, in FIG. 2, the first direction is a front-to-rear direction.

[0027] The evaporator 200 and the condenser 300 may each include a copper tube and a fin. A refrigerant (e.g., a refrigerant) may exchange heat with a gas flowing through the evaporator 200 or the condenser 300 by flowing through the copper tube. The fin is connected to the copper tube to increase a heat exchange area between the evaporator 200 or the condenser 300 and the gas flowing through the evaporator 200 or the condenser 300, thereby improving the heat exchange effect of the evaporator 200 or the condenser 300. The fin in the evaporator 200 may be made of a hydrophilic material (e.g., chromium, aluminum, zinc, etc.), so that the condensed water may flow downward along the surface of the evaporator 200. The hydrophilicity refers to a relatively excellent affinity of an object to water and the object can attract water molecules.

[0028] FIG. 5 is a cross-sectional view of a dehumidifier according to some embodiments.

[0029] 5, the liquid condenser 400 is located between the evaporator 200 and the condenser 300. The liquid condenser 400 can be installed between the evaporator 200 and the condenser 300 by increasing the distance between the evaporator 200 and the condenser 300.

[0030] Fig. 6 is a structural diagram of a liquid condenser according to some embodiments. Fig. 7 is a structural diagram of a first air passage in a dehumidifier according to some embodiments. Fig. 8 is a structural diagram of a second air passage in a dehumidifier according to some embodiments. The solid arrow in Fig. 7 indicates the flow direction of gas in first air passage 11, and the dotted arrow in Fig. 8 indicates the flow direction of gas in second air passage 12.

[0031] As shown in Fig. 6, liquid condenser 400 includes a plurality of liquid condensation tubes 410. The plurality of liquid condensation tubes 410 extend along a second direction and communicate with second air passage 12. The second direction is parallel to the length direction of dehumidifier 1 (e.g., the left-right direction in Fig. 2). For example, in Figs. 2 and 6, the second direction is from right to left. The second direction is perpendicular to the first direction.

[0032] In this case, as shown in FIG. 7, the gas in the first air passage 11 passes through the outer surface of the evaporator 200, the outer surfaces of the plurality of liquid condensation tubes 410, and the outer surface of the condenser 300 in this order. Then, the air enters the fan 50 and is exhausted from the dehumidifier 1 via the fan 50. As shown in FIG. 8, the gas in the second air passage 12 passes through the internal spaces of the liquid condensation tubes 410 and the outer surface of the condenser 300 in order. Then, the air enters the fan 50 and is exhausted from the dehumidifier 1 via the fan 50. .

[0033] For example, as shown in FIG. 7, the fan 50 draws a part of the indoor air into the housing 100 from the main inlet 101 of the dehumidifier 1. The part of the indoor air enters the first air passage 11 and exchanges heat with the evaporator 200, causing the moisture in the indoor air to condense into condensed water on the surface of the evaporator 200, thereby realizing dehumidification of the gas in the first air passage 11. The gas dehumidified by the evaporator 200 becomes low-temperature gas. As shown in FIG. 8, another part of the indoor air enters the housing 100 from the sub-inlet 102 of the dehumidifier 1, passes through the second air passage 12, and enters the plurality of liquid condensation tubes 410. In this case, the low-temperature gas that has passed through the evaporator 200 flows over the outer surfaces of the plurality of liquid condensation tubes 410 and exchanges heat with the other part of the indoor air in the plurality of liquid condensation tubes 410, causing the moisture in the other part of the indoor air to condense into condensed water, thereby realizing dehumidification of the gas in the second air passage 12. The dehumidified gas is then heated by the condenser 300 to further reduce the humidity in the gas, thereby turning the gas into dry gas of a suitable temperature and allowing it to flow into the indoor environment, thereby completing the dehumidification of the indoor air.

[0034] Fan 50 is configured to drive the flow of gas in first air passage 11 and second air passage 12. Driving the flow of gas by fan 50 can increase the flow rate of gas in first air passage 11 and second air passage 12. In this way, gas in first air passage 11 can exchange heat with evaporator 200 and condenser 300. In addition, when gas in second air passage 12 exchanges heat with condenser 300, the flow rate of gas entering first air passage 11 and second air passage 12 can be increased, thereby increasing the dehumidification amount of dehumidifier 1 and improving the dehumidification efficiency of dehumidifier 1.

[0035] In some embodiments of the present disclosure, the gas in the first air duct 11 can be cooled, condensed, and dehumidified by the evaporator 200, and the gas in the second air duct 12 can be cooled, condensed, and dehumidified by the low-temperature gas in the first air duct 11 in the plurality of liquid condensation tubes 410. In this way, the utilization rate of the low-temperature gas in the first air duct 11 can be improved, the dehumidification amount of the dehumidifier 1 can be increased, and the dehumidification efficiency of the dehumidifier 1 can be improved.

[0036] The following provides a detailed description of liquid condenser 400 according to several embodiments of the present disclosure.

[0037] Fig. 9 is another structural view of a liquid condenser according to some embodiments, Fig. 10 is a partially enlarged view of a circle B in Fig. 9, Fig. 11 is a partially enlarged view of a circle C in Fig. 9.

[0038] In some embodiments, as shown in Figs. 9 to 11, the plurality of liquid condensation tubes 410 are located in the first region 401, the second region 402, and the third region 403, respectively. The first region 401, the second region 402, and the third region 403 are sequentially arranged along a third direction. The third direction is parallel to the height direction of the dehumidifier 1 (e.g., the up-down direction in Fig. 2), and the third direction is perpendicular to the first direction and the second direction. For example, in Fig. 9, the third direction is a top-down direction. The plurality of liquid condensation tubes 410 are located in the first region 401, the second region 402, and the third region 403, respectively, and two or more liquid condensation tubes 410 are installed in each of the first region 401, the second region 402, and the third region 403. 9, the plurality of liquid condenser tubes 410 include a plurality of first sub-liquid condenser tubes 4101, a plurality of second sub-liquid condenser tubes 4102, and a plurality of third sub-liquid condenser tubes 4103. The plurality of first sub-liquid condenser tubes 4101 are located in the first region 401, the plurality of second sub-liquid condenser tubes 4102 are located in the second region 402, and the plurality of third sub-liquid condenser tubes 4103 are located in the third region 403.

[0039] In some embodiments, as shown in FIGS. 9 to 11, the spacing between two adjacent second sub-liquid condensate tubes 4102 is equal to or smaller than the spacing between two adjacent first sub-liquid condensate tubes 4101. Smaller,and The interval between two adjacent second sub-liquid condensation tubes 4102 is The interval between adjacent two third sub-liquid condenser tubes 4103 is smaller than the interval between adjacent two third sub-liquid condenser tubes 4103. In this manner, the distribution density of the liquid condenser tubes in the second region 402 is smaller than the distribution density of the liquid condenser tubes in the first region 401. Bigger, and The distribution density of the liquid condensate tubes in the second region 402 is The distribution density of the liquid condensate tubes is greater than that of the third region 403. Here, the distribution density of the liquid condensate tubes refers to the number of liquid condensate tubes 410 per unit area.

[0040] In the middle part of the evaporator 200 in the third direction, the supercooling phenomenon is likely to occur within a certain temperature range (for example, 12°C to 28°C). In addition, due to the air passage design of the dehumidifier 1, the flow rate of gas in the middle part of the evaporator 200 is relatively large. In this way, the amount of cooling of the low-temperature gas that has passed through the middle part of the evaporator 200 is relatively large compared to other parts of the evaporator 200. Meanwhile, in some embodiments of the present disclosure, the density of the plurality of second sub-liquid condensation tubes 4102 is higher than the density of the plurality of first sub-liquid condensation tubes 4101. Bigger, and The density of the plurality of second sub-liquid condensation tubes 4102 is Because the density of the multiple third sub-liquid condensation tubes 4103 is greater, the flow resistance of the low-temperature gas passing through the evaporator 200 in the multiple second sub-liquid condensation tubes 4102 is greater than the flow resistance in the multiple first sub-liquid condensation tubes 4101 or the multiple third sub-liquid condensation tubes 4103.

[0041] In this way, the contact time between the low-temperature gas and the plurality of second sub-liquid condensation tubes 4102 is relatively long. In addition, since the plurality of second sub-liquid condensation tubes 4102 are arranged closely together, the contact area between the plurality of second sub-liquid condensation tubes 4102 and the low-temperature gas is relatively large, so that the low-temperature gas exchanges heat sufficiently with the plurality of second sub-liquid condensation tubes 4102, and the dehumidifier 1 improves the utilization rate of the cold amount of the low-temperature gas flowing out from the evaporator 200, and further improves the dehumidification efficiency of the dehumidifier 1. Here, the supercooling phenomenon refers to a phenomenon in which a liquid cannot be frozen under a certain pressure when the temperature of the liquid is lower than the freezing point of the liquid under the pressure. The cold amount refers to the total energy value of the target space heat amount consumed by the equipment (e.g., dehumidifier) ​​by cooling per unit time, or the total energy value of the heat amount extracted from the target space.

[0042] In some embodiments, the liquid condenser 400 includes a plurality of first sub-liquid condenser tubes 4101. The first two adjacent sub-liquid condenser tubes 4101 4103 with intervals of 3rd sub-liquid condenser tubes The two adjacent third sub-liquid condenser tubes 4103 and the number of the plurality of first sub-liquid condensation tubes 4101 and the number of the plurality of third sub-liquid condensation tubes 4103 may be the same.

[0043] A plurality of first sub-liquid condensation tubes 4101 The first two adjacent sub-liquid condenser tubes 4101 4103 with intervals of 3rd sub-liquid condenser tubes The two adjacent third sub-liquid condenser tubes 4103 When the intervals between the first and third sub-liquid condensation tubes 4101 and 4103 are the same and the number of the first and third sub-liquid condensation tubes 4101 and 4103 is the same, the first and third sub-liquid condensation tubes 4101 and 4103 are symmetrically installed in the third direction, simplifying the structure of the liquid condenser 400 and facilitating the processing and manufacturing of the liquid condenser 400. In this case, the heat exchange efficiency between the first and third sub-liquid condensation tubes 4101 and 4103 and the low-temperature gas in the first air passage 11 is approximately the same, and the blowing speed of the first region 401 is the same as the blowing speed of the third region 403, improving the uniformity of the air blowing. The blowing speed may refer to the flow speed of the gas.

[0044] In some embodiments, the spacing between two adjacent second sub-liquid condensation tubes 4102 in the plurality of second sub-liquid condensation tubes 4102 may be the same. For example, having the spacing between two adjacent second sub-liquid condensation tubes 4102 in the plurality of second sub-liquid condensation tubes 4102 be the same may simplify the structure of the plurality of second sub-liquid condensation tubes 4102 and facilitate processing of the plurality of second sub-liquid condensation tubes 4102.

[0045] Of course, in some embodiments, the spacing between adjacent two second sub-liquid condensate tubes 4102 in the plurality of second sub-liquid condensate tubes 4102 may be different. For example, as shown in FIG. 9, the second region 402 may be No. 1 The central surface 4020 is No. 1 The central plane 4020 is located at the center of the second region 402 and perpendicular to the third direction. In this case, the central plane 4020 is parallel to the third direction and No. 1By decreasing the distance between two adjacent second sub-liquid condensation tubes 4102 in a direction close to the central plane 4020 (e.g., from top to bottom or from bottom to top), No. 1 Adjacent to the central plane 4020 Two The spacing between the second sub-liquid condensation tubes 4102 is No. 1 Adjacent to the center plane 4020 Two This is greater than the spacing between the second sub-liquid condensate tubes 4102. No. 1 The closer to the center plane 4020, the lower the amount of cold gas. Two By adjusting the interval of the second sub-liquid condensation tube 4102, No. 1 Second sub-liquid condensation pipe 4102 close to central plane 4020 can exchange heat sufficiently with the low-temperature gas in first air passage 11, and the dehumidification efficiency of dehumidifier 1 is further improved.

[0046] FIG. 12 is another structural diagram of a liquid condenser according to some embodiments.

[0047] In some embodiments, as shown in FIGS. 9 and 12, a plurality of second sub-liquid condensers 4102 may include: No. 1 By being arranged symmetrically with respect to the central plane 4020, the structure of the plurality of second sub-liquid condenser tubes 4102 is simplified, thereby simplifying the overall structure of the liquid condenser 400 and facilitating the processing of the liquid condenser 400.

[0048] In some embodiments, as shown in FIG. 6, the liquid condenser tube 410 includes an inlet end 411 and an outlet end 412. The gas in the second air passage 12 flows into the liquid condenser tube 410 from the inlet end 411 and flows out of the liquid condenser tube 410 from the outlet end 412. The gas flowing out from the outlet end 412 mixes with the gas that has passed through the evaporator 200 and the liquid condenser 400 in the first air passage 11 on the side (e.g., the front side) of the condenser 300 that is closer to the evaporator 200. Here, the front side of the condenser 300 refers to the front side of the condenser 300 in the flow direction of the gas in the first air passage 11, so that the gas in the first air passage 11 can first turn around the front side of the condenser 300 after passing through the evaporator 200 and the liquid condenser 400.

[0049] The indoor air entering second air passage 12 may enter liquid condenser tube 410 through suction end 411. The gas in liquid condenser tube 410 exchanges heat with the low-temperature gas in first air passage 11, and then is discharged from outlet end 412 and mixed with the gas in first air passage 11. The mixed gas flows to condenser 300, and after exchanging heat with condenser 300, the gas becomes dry gas at an appropriate temperature and is returned to the indoor environment.

[0050] For example, suction end 411 is one end along the axial direction of liquid condensation tube 410, and blowing end 412 is the other end along the axial direction of liquid condensation tube 410. In this way, the distance between suction end 411 and blowing end 412 of liquid condensation tube 410 can be made relatively large, the flow path of gas in liquid condensation tube 410 is relatively long, and the flow time is also long, so that the gas in liquid condensation tube 410 can fully exchange heat with the low-temperature gas in first air passage 11, and the moisture in the gas in liquid condensation tube 410 is condensed to form condensed water, and the dehumidification efficiency of dehumidifier 1 is further improved.

[0051] 6, in the second direction (e.g., from the suction end 411 to the outlet end 412), the liquid condensate tube 410 is inclined downward such that the suction end 411 is higher than the outlet end 412. In this manner, the condensed water in the liquid condensate tube 410 can flow rapidly due to gravity, avoiding accumulation of the condensed water in the liquid condensate tube 410, so that the condensed water can be rapidly discharged from the liquid condenser 400.

[0052] The inclination of the liquid condensate tube 410 may be greater than a set value (e.g., 3%). Thus, the inclination of the liquid condensate tube 410 may be relatively large, i.e., the inclination angle of the liquid condensate tube 410 with respect to the horizontal plane may be relatively large. In this case, the condensed water in the liquid condensate tube 410 can flow rapidly due to the action of gravity, and the accumulation of the condensed water in the liquid condensate tube 410 can be avoided, so that the condensed water can be rapidly discharged from the liquid condenser 400. Here, the inclination may be a ratio between a dimension L1 (shown in FIG. 6) of the liquid condensate tube 410 in the third direction of the orthogonal projection along the second direction and a dimension L2 (shown in FIG. 6) of the liquid condensate tube 410 in the second direction of the orthogonal projection along the third direction.

[0053] Fig. 13 is a structural diagram of a liquid condenser according to some embodiments. Fig. 14 is a partially enlarged view of the circle A in Fig. 13. Fig. 15 is a top view of a liquid condenser according to some embodiments. The solid arrow in Fig. 13 indicates the approximate flow direction of the gas in the first air passage 11. Figure 13 The dotted arrow indicates the approximate flow direction of gas in second air passage 12.

[0054] 6 and 13, the liquid condenser 400 further includes a first support plate 420 and a second support plate 430. The first support plate 420 and the second support plate 430 are respectively provided on both ends of the liquid condenser tube 410 in the second direction. The first support plate 420 and the second support plate 430 can support and fix the liquid condenser tube 410, which is advantageous to enhance the structural strength of the liquid condenser 400. The first support plate 420 and the second support plate 430 may be connected to the condenser 300 (for example, by engagement connection or screw connection), thereby realizing a fixed connection between the liquid condenser 400 and the condenser 300.

[0055] 13 and 14, the first support plate 420 is provided with a first suction cavity 441. The first suction cavity 441 communicates with a plurality of liquid condensation tubes 410. An end of the liquid condensation tube 410 close to the first support plate 420 (e.g., suction end 411) is connected to the bottom wall of the first suction cavity 441, and the suction end 411 of the liquid condensation tube 410 communicates with the first suction cavity 441.

[0056] The first suction cavity 441 communicates with the indoor environment through the sub-suction port 102 of the dehumidifier 1, so that some indoor air can flow into the first suction cavity 441. Then, the indoor air can enter the suction end 411 of the liquid condensation tube 410 from the first suction cavity 441, thereby avoiding the first support plate 420 from blocking the suction end 411 of the liquid condensation tube 410. The suction of the liquid condensation tube 410 is smooth, and the uniformity of the gas entering the liquid condensation tube 410 is improved.

[0057] Furthermore, as shown in FIG. 15, the other end of the liquid condensate tube 410 closer to the second support plate 430 (e.g., the blowing end 412) is connected to the second support plate 430 and passes through the second support plate 430, thereby preventing the second support plate 430 from blocking the blowing out of the liquid condensate tube 410 and the discharge of condensed water.

[0058] In some embodiments, as shown in FIG. 6, the length of the first support plate 420 is longer than the length of the second support plate 430 in the third direction. The second The center plane 4200 is aligned along the length of the second support plate 430. The corresponding third 15, the width of the first support plate 420 is greater than the width of the second support plate 430 in the first direction, and the width of the first support plate 420 is The corresponding fourth The center surface 4201 is located in the width direction of the second support plate 430. The corresponding fifth 6 and 15, the length of the first support plate 420 is longer than the length of the second support plate 430 in the third direction, and the length direction of the first support plate 420 is The second The center plane 4200 is aligned along the length of the second support plate 430. The corresponding third The first support plate 420 overlaps with the center plane 4300, and the width of the first support plate 420 is greater than the width of the second support plate 430 in the first direction. corresponds to The fourth center plane 4201 is the second support plate 430 corresponds to Width direction Fifth It overlaps with the center surface 4301. The second center plane 4200 passes through the center of the first support plate 420 and is perpendicular to the third direction. The third center plane 4300 passes through the center of the second support plate 430 and is perpendicular to the third direction. The fourth center plane 4201 passes through the center of the first support plate 420 and is perpendicular to the first direction. The fifth center plane 4301 passes through the center of the second support plate 430 and is perpendicular to the first direction.

[0059] In this case, the first support plate 420 and the second support plate 430 can be arranged in an orderly manner, the structure of the liquid condenser 400 is relatively regular, and the overall thickness of the liquid condenser 400 is relatively thin, which is advantageous for reducing the space occupied by the liquid condenser 400 and makes it easy to arrange the liquid condenser 400. In addition, the volume of the second support plate 430 is smaller than the volume of the first support plate 420, which can further reduce the volume of the liquid condenser 400 and makes it easy to install and remove the liquid condenser 400. In addition, the liquid condenser 400 is approximately conical in shape, which is advantageous for inserting and removing the liquid condenser 400 into and from the dehumidifier 1.

[0060] In some embodiments, the thickness of second support plate 430 is greater than 2 mm, and the thickness of first support plate 420 is greater than the thickness of second support plate 430, thereby facilitating the processing of first suction cavity 441. For example, the thickness of first support plate 420 and the thickness of second support plate 430 are 2 mm, 2.5 mm, 3 mm, etc. In this way, the thickness of first support plate 420 and the thickness of second support plate 430 are relatively thick, which is advantageous for improving the structural strength of liquid condenser 400 and improving the fixing reliability of liquid condenser 400.

[0061] In some embodiments, the corners of the inner wall of the first suction cavity 441 may be rounded corners. For example, the cross section of the first suction cavity 441 is rectangular, and the corners of the rectangle are circular arcs. In this way, the corners of the inner wall of the first suction cavity 441 are relatively smooth, which can avoid the formation of vortexes at the corners of the inner wall of the first suction cavity 441, and is favorable for reducing the wind resistance in the first suction cavity 441, so that the first suction cavity 441 can form a relatively uniform flow field distribution, and the gas flow is smooth, thereby improving the suction amount and suction uniformity of the liquid condenser 400.

[0062] In some embodiments, the other end (blowing end 412) of the liquid condensation tube 410 is located in the same plane as the side (e.g., the left side) of the second support plate 430 that is away from the first support plate 420. For example, the blowing end 412 of the liquid condensation tube 410 is flush with the left side of the second support plate 430. In this way, the condensed water in the liquid condensation tube 410 can flow gently from the side of the second support plate 430 that is away from the first support plate 420 along the direction closer to the second support plate 430 of the first support plate 420, thereby avoiding the condensed water from directly dripping and colliding with the flowing gas of the dehumidifier 1 and avoiding the condensed water from scattering.

[0063] In some embodiments, in a plane in which the first direction and the third direction lie, the cross section of the liquid condenser tube 410 may be at least one of a circle, an ellipse, and a teardrop shape. For example, among the plurality of liquid condenser tubes 410, the cross section of a first portion of the liquid condenser tubes 410 is a circle, the cross section of a second portion of the liquid condenser tubes 410 is an ellipse, and the cross section of a third portion of the liquid condenser tubes 410 is a teardrop shape.

[0064] Furthermore, the cross section of liquid condensation tube 410 is circular, elliptical, or teardrop-shaped, which can reduce the flow resistance of the gas in first air duct 11 caused by the outer surface of liquid condensation tube 410, thereby making the flow of gas in first air duct 11 smoother, facilitating the reduction of the energy consumption of fan 50, reducing the operating cost of dehumidifier 1, and improving the dehumidification efficiency of dehumidifier 1.

[0065] In some embodiments, in a plane in which the first direction and the third direction are located, the cross sections of the plurality of second sub-liquid condensation tubes 4102 may be teardrop-shaped, and the cross sections of the plurality of first sub-liquid condensation tubes 4101 and the plurality of third sub-liquid condensation tubes 4103 may each be circular. Since the air volume in the middle of the evaporator 200 is relatively large, the cross sections of the plurality of second sub-liquid condensation tubes 4102 are arranged in a teardrop shape, thereby reducing the wind resistance when the gas flows in the first air passage, and thereby reducing the energy consumption of the fan 50.

[0066] In some embodiments, the liquid condenser tubes 410 may be arranged in a row along the third direction. Alternatively, the liquid condenser tubes 410 may be arranged in multiple rows along the first direction. In addition, in the first direction, the positions of the liquid condenser tubes 410 in the multiple rows of liquid condenser tubes 410 may be aligned with each other, or the positions of the liquid condenser tubes 410 in at least two rows of the multiple rows of liquid condenser tubes 410 may be offset from each other.

[0067] In some embodiments, the liquid condenser tube 410 may be a metal tube (e.g., a copper tube). The inner wall of the liquid condenser tube 410 is provided with a hydrophobic layer. The hydrophobic layer may be a hydrophobic compound coating (e.g., a fluorosilane polymer), thereby forming a hydrophobic surface on the inner wall of the liquid condenser tube 410, thereby improving the condensation heat exchange coefficient of the inner wall of the liquid condenser tube 410, and allowing the low-temperature gas in the first air passage 11 to exchange heat with the gas in the liquid condenser tube 410, thereby improving the heat exchange effect. In this way, the liquid condenser tube 410 can have a relatively excellent condensation effect, thereby reducing the water content of the gas in the liquid condenser tube 410. Note that when water vapor contacts a solid wall surface that is lower than the vapor saturation temperature, the water vapor releases latent heat of vaporization and condenses to form liquid water, and this process may be called condensation heat exchange. In some embodiments, the material of the liquid condenser 410 may be Vinylidene fluoride.

[0068] The above description has been mainly focused on the plurality of second sub-liquid condensation tubes 4102 in the liquid condenser 400. The adjacent two second sub-liquid condenser tubes 4102 The intervals between the first sub-liquid condensation tubes 4101 are The first two adjacent sub-liquid condenser tubes 4101 Interval The distance between two adjacent second sub-liquid condensation tubes 4102 among the plurality of second sub-liquid condensation tubes 4102 is smaller than the distance between adjacent two second sub-liquid condensation tubes 4102. Multiple 3rd sub-liquid condenser tubes 4103 The two adjacent third sub-liquid condenser tubes 4103 Of course, in some embodiments, the liquid condenser tubes 410 in the liquid condenser 400 may include other arrangements.

[0069] 16 and 17 are schematic diagrams of another liquid condenser according to some embodiments.

[0070] As shown in FIGS. 16 and 17 , in a plane in which the first direction and the third direction are located, the cross-sectional area of ​​any one of the plurality of second sub-liquid condensation tubes 4102 is smaller than the cross-sectional area of ​​any one of the plurality of first sub-liquid condensation tubes 4101. and the cross-sectional area of ​​any one of the plurality of second sub-liquid condensation tubes 4102 is greater than or equal toThe cross-sectional area of ​​any one of the plurality of third sub-liquid condensation tubes 4103 is larger than that of any one of the plurality of third sub-liquid condensation tubes 4103. In this case, the contact area between any one of the plurality of second sub-liquid condensation tubes 4102 and the gas in the first air passage 11 is larger than the contact area between any one of the plurality of first sub-liquid condensation tubes 4101 and the gas in the first air passage 11. Bigger , and The contact area between any one of the plurality of second sub-liquid condensation tubes 4102 and the gas in the first air passage 11 is The contact area is larger than the contact area between any of the plurality of third sub-liquid condensation tubes 4103 and the gas in first air passage 11 .

[0071] 16 and 17, in the first direction, the sides (e.g., rear sides) of the plurality of first sub-liquid condensing tubes 4101 closer to the condenser 300, the sides (e.g., rear sides) of the plurality of second sub-liquid condensing tubes 4102 closer to the condenser 300, and the sides (e.g., rear sides) of the plurality of third sub-liquid condensing tubes 4103 closer to the condenser 300 are located on the same plane. For example, in the first direction, the rear sides of the plurality of first sub-liquid condensing tubes 4101, the rear sides of the plurality of second sub-liquid condensing tubes 4102, and the rear sides of the plurality of third sub-liquid condensing tubes 4103 are flush with each other, thereby simplifying the structure of the liquid condenser 400, regularizing the structure of the sides (e.g., rear sides) of the plurality of liquid condensing tubes 410 closer to the condenser 300, and facilitating the positioning of the liquid condenser 400 when manufacturing the liquid condenser 400. In addition, the low-temperature gas that has passed through the evaporator 200 can flow smoothly to the first area 401, the second area 402, and the third area 403, preventing the gas from forming a reflux, thereby reducing the wind resistance of the gas in the first air passage 11 and making the airflow uniform.

[0072] 16 and 17, in the first direction, the sides (e.g., front sides) of the plurality of second sub-liquid condensation tubes 4102 closer to the evaporator 200 are closer to the evaporator 200 than the sides (e.g., front sides) of the plurality of first sub-liquid condensation tubes 4101 closer to the evaporator 200 and the sides (e.g., front sides) of the plurality of third sub-liquid condensation tubes 4103 closer to the evaporator 200. For example, the extension lengths of the plurality of second sub-liquid condensation tubes 4102 in the first direction are shorter than the extension lengths of the plurality of first sub-liquid condensation tubes 4101. Longer, and The extension length of the plurality of second sub-liquid condensation tubes 4102 isThe extension length of the plurality of third sub-liquid condensation tubes 4103 is longer than that of the plurality of second sub-liquid condensation tubes 4102. In this manner, the contact area between the plurality of second sub-liquid condensation tubes 4102 and the low-temperature gas in the first air passage 11 is relatively large, and the heat exchange time is relatively long, thereby improving the heat exchange effect of the liquid condenser 400 and, in turn, improving the dehumidification effect of the dehumidifier 1. The two adjacent second sub-liquid condenser tubes 4102 By making the interval in the third direction approximately constant, an increase in flow resistance of the gas in first air passage 11 when it passes through second sub-liquid condensate pipe 4102 is avoided.

[0073] Figure 18 is yet another structural diagram of another liquid condenser according to some embodiments. Figure 19 is a top view of another liquid condenser according to some embodiments.

[0074] 18 and 19, in some embodiments, the liquid condenser 400 further includes a plurality of second exhaust holes 450. The plurality of second exhaust holes 450 are provided on the side (e.g., rear side) of the plurality of liquid condenser tubes 410 facing the condenser 300, respectively, and one liquid condenser tube 410 may be provided with one or more second exhaust holes 450. Two adjacent second exhaust holes 450 are installed at intervals along the length of the liquid condensation tube 410, thereby increasing the heat exchange area between the gas flowing out of the liquid condensation tube 410 and the condenser 300. In addition, by providing a plurality of second exhaust holes 450, the flow rate of the gas sucked into the liquid condensation tube 410 by the fan 50 can be increased, increasing the amount of air passing through the condenser 300, thereby improving the heat exchange effect of the condenser 300.

[0075] In some embodiments, the number of second exhaust holes 450 in one liquid condensation tube 410 is equal to or less than a first set value (e.g., 5), and the distance between each second exhaust hole 450 and the suction end 411 is greater than the distance between the second exhaust hole 450 and the blowing end 412. The distance between any two second exhaust holes 450 of the plurality of second exhaust holes 450 is smaller than one-third of the length of the liquid condensation tube 410, and the hole diameter of the second exhaust hole 450 is smaller than the inner diameter of the liquid condensation tube 410. In this way, the heat exchange time between the gas in the liquid condensation tube 410 and the gas in the first air passage 11 is sufficient, so that the moisture in the gas in the liquid condensation tube 410 is sufficiently condensed, and the dehumidification effect of the dehumidifier 1 can be improved.

[0076] The above description is mainly about the fact that the cross-sectional area of ​​any one of the plurality of second sub-liquid condensation tubes 4102 is smaller than the cross-sectional area of ​​any one of the plurality of first sub-liquid condensation tubes 4101. and the cross-sectional area of ​​any one of the plurality of second sub-liquid condensation tubes 4102 is This is explained by taking as an example a case where the cross-sectional area is larger than that of any one of the plurality of third sub-liquid condensation tubes 4103 .

[0077] Figure 20 is a structural diagram of yet another liquid condenser according to some embodiments. Figure 21 is a structural diagram of yet another liquid condenser from another perspective according to some embodiments.

[0078] 20 and 21, in the first direction, the number of rows of the multiple second sub-liquid condensation tubes 4102 is greater than the number of rows of the multiple first sub-liquid condensation tubes 4101 and the multiple third sub-liquid condensation tubes 4103. In this way, by installing a relatively large number of rows of liquid condensation tubes 410 in the second region 402, the cross-sectional area of ​​the multiple second sub-liquid condensation tubes 4102 can be indirectly increased, thereby reducing the contact area between the multiple second sub-liquid condensation tubes 4102 and the gas in the first air passage 11 and the contact area between the multiple first sub-liquid condensation tubes 4101 and the gas in the first air passage 11. and the contact area between the plurality of second sub-liquid condensation pipes 4102 and the gas in the first air passage 11 is made larger. The contact area between the plurality of third sub-liquid condensation pipes 4103 and the gas in first air passage 11 can be made larger.

[0079] In addition, the amount of cooling of the low-temperature gas that passes through the middle part of the evaporator 200 is greater than the amount of cooling of the low-temperature gas that passes through other parts of the evaporator 200, i.e., the amount of cooling of the low-temperature gas in the first region 401 and the amount of cooling of the low-temperature gas in the third region 403 are relatively low. Therefore, by installing multiple rows of second sub-liquid condensation tubes 4102, the multiple second sub-liquid condensation tubes 4102, the multiple first sub-liquid condensation tubes 4101 and the multiple third sub-liquid condensation tubes 4103 can be matched to the amount of cooling of the low-temperature gas at their respective positions, thereby improving the utilization rate of the amount of cooling and the dehumidification efficiency of the dehumidifier 1, reducing energy consumption and saving costs.

[0080] In some embodiments, when the number of rows of the plurality of first sub-liquid condensing tubes 4101 and the number of rows of the plurality of third sub-liquid condensing tubes 4103 are the same in the first direction, the liquid condenser 400 satisfies at least one of the following: the interval between two adjacent first sub-liquid condensing tubes 4101 may be the same as the interval between two adjacent third sub-liquid condensing tubes 4103; and the number of the plurality of first sub-liquid condensing tubes 4101 may be the same as the number of the plurality of third sub-liquid condensing tubes 4103. In this way, the plurality of first sub-liquid condensing tubes 4101 and the plurality of third sub-liquid condensing tubes 4103 are symmetrically installed in the third direction, thereby simplifying the structure of the liquid condenser 400 and facilitating the processing of the liquid condenser 400. In addition, the heat exchange efficiency between the multiple first sub-liquid condensation tubes 4101 and the multiple third sub-liquid condensation tubes 4103 and the low-temperature gas in the first air passage 11 may be approximately the same, and the blowing speed of the first area 401 is the same as the blowing speed of the third area 403, thereby improving the uniformity of the air supply.

[0081] Of course, when the number of rows of the first sub-liquid condensation tubes 4101 is different from the number of rows of the third sub-liquid condensation tubes 4103, Two The spacing of the first sub-liquid condensate tubes 4101, adjacent TwoThe spacing between the third sub-liquid condensation tubes 4103, the number of the plurality of first sub-liquid condensation tubes 4101, and the number of the plurality of third sub-liquid condensation tubes 4103 can satisfy the above conditions. In some embodiments, as shown in Figures 20 and 21, the plurality of second sub-liquid condensation tubes 4102 are arranged in two rows along the first direction, and among the two rows of second sub-liquid condensation tubes 4102, one row of second sub-liquid condensation tubes 4102 closer to the evaporator 200 is referred to as a first row liquid condensation tube 413, and the other row of second sub-liquid condensation tubes 4102 farther from the evaporator 200 is referred to as a second row liquid condensation tube 414.

[0082] The first row liquid condenser tube 413 and the second row liquid condenser tube 414 are arranged in order along the first direction. The number of liquid condenser tubes 410 in the first row liquid condenser tube 413 is the same as the number of liquid condenser tubes 410 in the second row liquid condenser tube 414, and the liquid condenser tubes 410 in the first row liquid condenser tube 413 correspond to the liquid condenser tubes 410 in the second row liquid condenser tube 414. For example, the liquid condenser tubes 410 in the first row liquid condenser tube 413 are at the same height as the corresponding liquid condenser tubes 410 in the second row liquid condenser tube 414. In a plane in which the first direction and the third direction are located, the cross-sectional area of ​​any liquid condenser tube 410 in the first row liquid condenser tube 413 is larger than the cross-sectional area of ​​any liquid condenser tube 410 in the second row liquid condenser tube 414.

[0083] The number of liquid condensation tubes 410 in the first row liquid condensation tube 413 and the second row liquid condensation tube 414 are the same and the positions correspond to each other, so that the adjacent liquid condensation tubes 410 in the first row liquid condensation tube 413 Two The gaps between the liquid condenser tubes 410 and the adjacent second row liquid condenser tubes 414 Two The gaps between the liquid condenser tubes 410 may be the same. Two The gap between the liquid condensation tubes 410 refers to the gap between adjacent first row liquid condensation tubes 413. Two This refers to the distance between the central axes of the liquid condenser tubes 410. Two The gap between the liquid condenser tubes 410 refers to the gap between adjacent second row liquid condenser tubes 414. Two This refers to the distance between the central axes of the liquid condensate tubes 410.

[0084] In this case, the gas in first air passage 11 passes through the gaps in first-row liquid condensation tube 413, and then directly enters the gaps in second-row liquid condensation tube 414, and can flow to condenser 300. In this way, the flow resistance in liquid condenser 400 caused by the gas in first air passage 11 can be reduced, and the air flow becomes smooth.

[0085] In some embodiments, in a plane in which the first direction and the third direction lie, the cross-sectional areas of the liquid condensation tubes 410 in the first row liquid condensation tube 413 are the same, and the cross-sectional areas of the liquid condensation tubes 410 in the second row liquid condensation tube 414 are the same, and the cross-sectional area of ​​the liquid condensation tubes 410 in the first row liquid condensation tube 413 is larger than the cross-sectional area of ​​the liquid condensation tubes 410 in the second row liquid condensation tube 414. In this way, it is possible to reduce vortexes of the gas in the first air passage 11 on the side (e.g., the rear side) of the second row liquid condensation tube 414 that is away from the first row liquid condensation tube 413, thereby reducing the form resistance caused by the vortexes and smoothing the flow of the airflow in the first air passage 11, and ultimately reducing the energy consumption of the fan 50.

[0086] In addition, the first sub-liquid condenser tube 4101 and the third sub-liquid condenser tube 4103 may be arranged in a row, and the multiple first sub-liquid condenser tubes 4101 and the multiple third sub-liquid condenser tubes 4103 may be located in the same row as the second row liquid condenser tube 414. In this case, in a plane in which the first direction and the third direction are located, the cross-sectional area of ​​the liquid condenser tube 410 in the second row liquid condenser tube 414, the cross-sectional area of ​​the multiple first sub-liquid condenser tubes 4101, and the cross-sectional area of ​​the multiple third sub-liquid condenser tubes 4103 may be the same, and the cross-sectional area of ​​the liquid condenser tube 410 in the first row liquid condenser tube 413 may be smaller than the cross-sectional area of ​​the multiple first sub-liquid condenser tubes 4101. and the cross-sectional area of ​​the liquid condenser tube 410 in the first row liquid condenser tube 413 is The cross-sectional area is larger than that of the plurality of third sub-liquid condenser tubes 4103.

[0087] The above description has been given mainly with reference to an example in which the gas in second air passage 12 enters liquid condenser tubes 410 from one side of liquid condenser 400. Of course, in some embodiments, the gas in second air passage 12 may enter liquid condenser tubes 410 via different sides of liquid condenser 400.

[0088] Fig. 22 is a structural diagram of yet another liquid condenser according to some embodiments, and the dotted arrow in Fig. 22 indicates the flow direction of gas in second air passage 12. Fig. 23 is a structural diagram of yet another liquid condenser according to some embodiments. Fig. 24 is a structural diagram of yet another liquid condenser according to some embodiments.

[0089] As shown in FIGS. 22 to 24, the liquid condenser 400 includes: subject 461, a first suction cavity 441, and a second suction cavity 451. The first suction cavity 441 and the second suction cavity 451 are respectively subject 461 on different sides, and subject The gas in first air passage 11 passes through the outer surface of evaporator 200, the outer surface of liquid condenser 400, and the outer surface of condenser 300, in this order, and the gas in second air passage 12 passes through first suction cavity 441 and second suction cavity 451, in this order. subject It flows through the inside of 461 and the outer surface of condenser 300 .

[0090] For example, as shown in FIG. 24, the first suction cavity 441 and the second suction cavity 451 are subject 461 in the second direction (for example, on both the left and right sides).

[0091] Fig. 25 is a structural diagram of a housing according to some embodiments. Fig. 26 is another structural diagram of a second air passage in a dehumidifier according to some embodiments.

[0092] 25 and 26, in addition to the main suction port 101, the housing 100 is further provided with a first suction port 103 and a second suction port 104. The first suction port 103 and the second suction port 104 communicate with the second air passage 12, the first suction port 103 corresponds to the first suction cavity 441 and is close to the first suction cavity 441, and the second suction port 104 corresponds to the second suction cavity 451 and is close to the second suction cavity 451.

[0093] For details on the flow direction of the gas in first air passage 11, please refer to the related contents described above, and therefore will not be repeated here. As shown in Fig. 26, regarding the flow direction of the gas in second air passage 12, a part of the indoor air enters housing 100 through first suction port 103, flows into first suction cavity 441, and then flows out of first suction cavity 441. subject Some of the indoor air may enter the housing 100 through the second suction port 104, flow into the second suction cavity 451, and then flow out through the second suction cavity 451. subject In this case, the low-temperature gas that has passed through the evaporator 200 may enter the subject Flowing over the outer surface of 461, subject By exchanging heat with the gas in 461, subject The moisture in the gas in 461 is condensed into condensed water, thereby achieving dehumidification of the gas in second air passage 12. Thereafter, the dehumidified gas is heated by condenser 300, which further reduces the humidity in the gas, causing the gas to become dry gas of an appropriate temperature and flow into the indoor environment, thereby completing the dehumidification of the indoor air.

[0094] In some embodiments, the first suction cavity 441 and the second suction cavity 451 may be symmetrically disposed with respect to the central plane of the liquid condenser 400 in the second direction, so as to simplify the structure of the liquid condenser 400 and facilitate the processing of the liquid condenser 400. In this way, the suction structure of the liquid condenser 400 in the second direction is the same, and the suction of the liquid condenser 400 is uniform.

[0095] In some embodiments of the present disclosure, the amount of air entering the liquid condenser 400 can be increased by providing multiple suction cavities. In this way, the low-temperature gas in the first air passage 11 can exchange heat with a relatively large amount of gas in the liquid condenser 400, improving the utilization rate of the cold amount of the low-temperature gas that has passed through the evaporator 200, and thereby improving the dehumidification amount of the dehumidifier 1. The first suction cavity 441 and the second suction cavity 451 can simultaneously suck in, thereby increasing the amount of air sucked in by the liquid condenser 400.

[0096] The first suction cavity 441 and the second suction cavity 451 are subject By installing the cavity 461 on both sides in the second direction, the distance between the first suction cavity 441 and the second suction cavity 451 can be increased. In this way, the suction of the first suction cavity 441 and the suction of the second suction cavity 451 do not interfere with each other, so that the suction of the first suction cavity 441 and the suction of the second suction cavity 451 are smooth.

[0097] In addition, by installing a first suction port 103 and a second suction port 104 corresponding to the first suction cavity 441 and the second suction cavity 451, respectively, the suction volume of the first suction cavity 441 and the second suction cavity 451 can be increased, and the air volume in the second air passage 12 can be increased, thereby improving the dehumidification efficiency of the dehumidifier 1.

[0098] In some embodiments, as shown in FIG. 24, the liquid condenser 400 further includes a first exhaust 431, which is subject 461 , and the first exhaust hole 431 communicates with the first suction cavity 441 and the second suction cavity 451 . subject The gas flowing into 461 can flow to the outer surface of the condenser 300 through the first exhaust hole 431. In this manner, the gas discharged from the first exhaust hole 431 can mix with the gas in the first air passage 11 on the side of the condenser 300 closer to the evaporator 200 (e.g., the front side). The mixed gas flows to the condenser 300 and exchanges heat with the condenser 300, and the gas heated by the condenser 300 can be returned to the indoor environment as dry gas at an appropriate temperature. Of course, in some embodiments, the liquid condenser 400 may include multiple first exhaust holes 431.

[0099] In some embodiments, as shown in FIGS. subject The liquid condenser 461 includes a first liquid condenser tube 471 and a second liquid condenser tube 472, and the first liquid condenser tube 471 and the second liquid condenser tube 472 are arranged along the second direction. One end of the first liquid condenser tube 471 communicates with the first suction cavity 441, and the first liquid condenser tube 471The other end of the second liquid condensation pipe 472 communicates with the second suction cavity 451 and the other end of the second liquid condensation pipe 472 communicates with the first exhaust hole 431.

[0100] The gas in second air passage 12 has two flow paths. In one flow path, the gas flows through first suction cavity 441, first liquid condenser tube 471, and first exhaust hole 431 in order, and then flows to condenser 300 via first exhaust hole 431. In the other flow path, the gas flows through second suction cavity 451, second liquid condenser tube 472, and first exhaust hole 431 in order, and then flows to condenser 300 via first exhaust hole 431. By providing multiple flow paths, the flow rate of the gas in second air passage 12 can be increased, thereby improving the dehumidification efficiency of dehumidifier 1.

[0101] In some embodiments, as shown in Figures 22-24, in a direction from the first suction cavity 441 to the second suction cavity 451 (e.g., the second direction), the first liquid condensate tube 471 is inclined downward. In a direction from the second suction cavity 451 to the first suction cavity 441 (e.g., opposite the second direction), the second liquid condensate tube 472 is inclined downward.

[0102] In this case, the one end of the first liquid condensate pipe 471 close to the first suction port 103 is higher than the other end of the first liquid condensate pipe 471 away from the first suction port 103, and the one end of the second liquid condensate pipe 472 close to the second suction port 104 is higher than the other end of the second liquid condensate pipe 472 away from the second suction port 104. In this way, the condensed water in the first liquid condensate pipe 471 and the condensed water in the second liquid condensate pipe 472 can flow rapidly due to gravity, avoiding accumulation of the condensed water in the first liquid condensate pipe 471 and the second liquid condensate pipe 472, so that the condensed water can be rapidly discharged from the liquid condenser 400.

[0103] For example, the inclination of the first liquid condenser tube 471 and the inclination of the second liquid condenser tube 472 are each greater than a second set value (e.g., 3%). Thus, the inclination of the first liquid condenser tube 471 and the inclination of the second liquid condenser tube 472 are relatively large, and the inclination angles of the first liquid condenser tube 471 and the second liquid condenser tube 472 with respect to the horizontal plane are relatively large. The condensed water in the first liquid condenser tube 471 and the condensed water in the second liquid condenser tube 472 can flow rapidly due to the action of gravity, which avoids the accumulation of the condensed water in the first liquid condenser tube 471 and the second liquid condenser tube 472, and therefore the condensed water can be rapidly discharged from the liquid condenser 400.

[0104] In some embodiments, as shown in FIGS. subject 461 further includes a gas collection tube 480 , a water outlet hole 432 , a first support plate 420 , and a second support plate 430 .

[0105] The gas collection pipe 480 is connected to and communicates with the other end of the first liquid condensation pipe 471 and the other end of the second liquid condensation pipe 472. The first exhaust hole 431 is provided on a side of the gas collection pipe 480 closer to the condenser 300 (e.g., the rear side). The water outlet hole 432 is provided at the bottom of the gas collection pipe 480 and is used to discharge condensed water. The first support plate 420 and the second support plate 430 are provided on both ends of the main body 461, respectively. The first suction cavity 441 is provided in the first support plate 420. For example, the side of the first support plate 420 facing away from the body 461 is recessed to form the first suction cavity 441. The one end of the first liquid condenser pipe 471 is connected to the bottom wall of the first suction cavity 441. The second suction cavity 451 is provided in the second support plate 430. For example, the side of the second support plate 430 facing away from the body 461 is recessed to form the second suction cavity 451. The one end of the second liquid condenser pipe 472 is connected to a bottom wall of the second suction cavity 451. The first support plate 420 and the second support plate 430 are spaced apart from each other along the second direction.

[0106] In this case, moisture in the gas in the second air passage 12 can be condensed in the first liquid condensation pipe 471 and the second liquid condensation pipe 472, and the condensed gas can flow to the gas collection pipe 480 and flow to the condenser 300 via the first exhaust hole 431 of the gas collection pipe 480. In addition, the condensed water in the first liquid condensation pipe 471 and the second liquid condensation pipe 472 can be discharged by the water outlet hole 432 of the gas collection pipe 480, thereby preventing the accumulation of condensed water in the first liquid condensation pipe 471, the second liquid condensation pipe 472, and the gas collection pipe 480.

[0107] In addition, the one end of the first liquid condensing pipe 471 may be connected to the first suction cavity 441 on the first support plate 420, so that the gas in the second air passage 12 can enter the first liquid condensing pipe 471 from the first suction cavity 441, and the first support plate 420 is prevented from blocking the first liquid condensing pipe 471, so that the first liquid condensing pipe 471 can be smoothly suctioned. The one end of the second liquid condensing pipe 472 may be connected to the second suction cavity 451 on the second support plate 430, so that the gas in the second air passage 12 can enter the second liquid condensing pipe 472 from the second suction cavity 451, and the second support plate 430 is prevented from blocking the second liquid condensing pipe 472, so that the second liquid condensing pipe 472 can be smoothly suctioned. In this way, the uniformity of the gas entering the first liquid condensate tube 471 and the uniformity of the gas entering the second liquid condensate tube 472 can be improved.

[0108] In some embodiments, the inside of the gas collection pipe 480 may be hollow or may be provided with a filling material. When the inside of the gas collection pipe 480 is hollow, the flow resistance of the gas in the gas collection pipe 480 is relatively small, thereby reducing the energy consumption of the fan 50. When the inside of the gas collection pipe 480 is provided with a filling material, the flow speed of the gas in the gas collection pipe 480 is reduced, thereby lengthening the heat exchange time between the gas in the gas collection pipe 480 and the low-temperature gas in the first air passage 11, and increasing the heat exchange amount, thereby improving the dehumidification effect of the dehumidifier 1 and improving the dehumidification efficiency of the dehumidifier 1. Of course, the internal structure of the gas collection pipe 480 may be set according to the configuration of the dehumidifier 1.

[0109] In some embodiments, the inner diameter of the gas collection pipe 480 is larger than the inner diameter of the first liquid condenser pipe 471 and the inner diameter of the second liquid condenser pipe 472. In this way, the flow resistance of the gas in the gas collection pipe 480 can be made relatively small, which increases the blowing amount of the liquid condenser 400 and increases the flow speed of the gas in the gas collection pipe 480, thereby reducing the energy consumption of the fan 50 and reducing costs.

[0110] In some embodiments, as shown in Figures 22 to 24, the gas collection tube 480 extends along the third direction. The adjacent two first exhaust holes 431 are installed at intervals in the gas collection pipe 480 along the third direction. The distance between any one of the multiple first exhaust holes 431 and an end (e.g., an upper end) of the gas collection pipe 480 that is far from the water outlet hole 432 is greater than the distance between the first exhaust hole 431 and an end (e.g., a lower end) of the gas collection pipe 480 that is close to the water outlet hole 432. The upper end of the gas collection pipe 480 can be closed.

[0111] In this case, the position of the multiple first exhaust holes 431 is close to the lower end of the gas collection pipe 480, and thus the gas that has passed through the first liquid condensation pipe 471 and the second liquid condensation pipe 472 can remain in the gas collection pipe 480 for a long time after entering the gas collection pipe 480, thereby increasing the heat exchange time between the gas in the second air passage 12 and the gas in the first air passage 11 and increasing the amount of heat exchange, thereby improving the dehumidification efficiency of the dehumidifier 1.

[0112] Of course, in some embodiments, the first exhaust holes 431 may be evenly arranged along the extension direction of the gas collection pipe 480 to simplify the structure of the gas collection pipe 480 and facilitate processing. In addition, the blowing out of the gas collection pipe 480 can be made uniform, and the blowing amount of the gas collection pipe 480 can be increased. In this way, most of the gas in the second air passage 12 can sufficiently exchange heat with the condenser 300 after passing through the liquid condenser 400.

[0113] The above description is mainly based on the example in which the gas collection pipe 480 extends along the third direction, but of course, in some embodiments, the gas collection pipe 480 may extend along other directions.

[0114] 27 and 28 are schematic diagrams of yet another liquid condenser according to some embodiments.

[0115] 27 and 28, the gas collection pipe 480 extends along the second direction, and the water outlet hole 432 is located at the center of the gas collection pipe 480 in the second direction. When the liquid condenser 400 includes a plurality of first exhaust holes 431, the distance between any one of the plurality of first exhaust holes 431 and the center of the gas collection pipe 480 in the extension direction is greater than the distance between the first exhaust hole 431 and both ends of the gas collection pipe 480 that are away from the water outlet hole 432. Here, both ends of the gas collection pipe 480 may be closed.

[0116] In this manner, the first exhaust holes 431 may be located near the center of the extension direction of the gas collection pipe 480, and the gas discharged from the first exhaust holes 431 may flow to the center portion of the condenser 300, improving the efficiency of heat exchange between the gas in the second air passage 12 and the condenser 300. In addition, the time for heat exchange between the gas in the main body 461 and the gas in the first air passage 11 is relatively long, subject The gas in 461 and the gas in first air passage 11 can exchange heat sufficiently, thereby improving the dehumidification efficiency of dehumidifier 1.

[0117] In some embodiments, the distance between the water outlet hole 432 and the first liquid condensate pipe 471 and the distance between the water outlet hole 432 and the second liquid condensate pipe 472 are the same, so that the discharge rates of the condensed water in the first liquid condensate pipe 471 and the condensed water in the second liquid condensate pipe 472 are approximately the same.

[0118] In some embodiments, as shown in Figures 27 and 28, the gas collection tube 480 is inclined upward from the center of its length to its ends. In either direction (e.g., from right to left or from left to right) from the center of the extension direction of the gas collection tube 480 to both ends of the gas collection tube 480, the gas collection tube 480 is inclined upward, so that both ends in the extension direction of the gas collection tube 480 are higher than the center of the gas collection tube 480. In this way, the water outlet hole 432 may be located at the bottom of the gas collection tube 480, and the condensed water in the gas collection tube 480 can flow rapidly due to gravity, avoiding the accumulation of condensed water in the gas collection tube 480, so that the condensed water can be rapidly discharged from the liquid condenser 400. In addition, the gas in the gas collection tube 480 can also flow rapidly to the first exhaust hole 431, and the flow of the gas can be smooth.

[0119] 27 and 28, first liquid condenser tube 471 includes a first liquid condenser portion 473 and a second liquid condenser portion 474. First liquid condenser portion 473 is inclined downward in the second direction (from left to right) such that one end (left end) of first liquid condenser portion 473 close to first suction cavity 441 is higher than the other end (right end) of first liquid condenser portion 473 away from first suction cavity 441. The left end of first liquid condenser portion 473 communicates with first suction cavity 441. The second liquid condenser 474 extends along the third direction, and one end (upper end) of the second liquid condenser 474 away from the gas collection pipe 480 is connected to the other end of the first liquid condenser 473, and the other end (lower end) of the second liquid condenser 474 closer to the gas collection pipe 480 is connected to the gas collection pipe 480.

[0120] The second liquid condenser pipe 472 includes a third liquid condenser portion 475 and a fourth liquid condenser portion 476. The third liquid condenser portion 475 is inclined downward in the opposite direction to the second direction (from right to left), so that one end (right end) of the third liquid condenser portion 475 close to the second suction cavity 451 is higher than the other end (left end) of the third liquid condenser portion 475 away from the second suction cavity 451. The right end of the third liquid condenser portion 475 communicates with the second suction cavity 451. The fourth liquid condenser portion 476 extends along the third direction, and one end (upper end) of the fourth liquid condenser portion 476 away from the gas collection pipe 480 communicates with the other end of the third liquid condenser portion 475, and the other end (lower end) of the fourth liquid condenser portion 476 close to the gas collection pipe 480 communicates with the gas collection pipe 480.

[0121] In this case, the length of the first liquid condensation pipe 471 and the length of the second liquid condensation pipe 472 may be made relatively long. In this way, the gas in the first liquid condensation pipe 471 can flow in the first liquid condensation pipe 471 for a relatively long time, and the gas in the second liquid condensation pipe 472 can flow in the second liquid condensation pipe 472 for a relatively long time, so that the gas in the first liquid condensation pipe 471 and the gas in the second liquid condensation pipe 472 can exchange heat with the low-temperature gas in the first air passage 11 for a relatively long time, improving the heat exchange efficiency of the liquid condenser 400 and further improving the dehumidification efficiency of the dehumidifier 1.

[0122] The principles and beneficial effects of the inclined installation of the first liquid condenser section 473 and the third liquid condenser section 475 are essentially the same as those of the inclined installation of the liquid condenser tube 410 described above, and will not be repeated here.

[0123] In some embodiments, as shown in FIG. subject 461 includes a plurality of first liquid condensation tubes 471, and the plurality of first liquid condensation tubes 471 include a first tube 491 and a second tube 492. The first liquid condensation section 473 of the first tube 491 is located on the side (e.g., the upper side) of the first liquid condensation section 473 of the second tube 492 that is away from the gas collection tube 480, and the second liquid condensation section 474 of the first tube 491 is located on the side (left side) of the second liquid condensation section 474 of the second tube 492 that is away from the first suction cavity 441.

[0124] subject 461 includes a plurality of second liquid condensation tubes 472, and the plurality of second liquid condensation tubes 472 include a third tube 423 and a fourth tube 424. A third liquid condenser section 475 of the third tube 423 is located on a side (e.g., an upper side) of the third liquid condenser section 475 of the fourth tube 424 that is away from the gas collection tube 480, and a fourth liquid condenser section 476 of the third tube 424 is located on a side (right side) of the fourth liquid condenser section 476 of the fourth tube 424 that is away from the second suction cavity 451.

[0125] In this way, the first pipe 491 and the second pipe 492 are regularly arranged and spaced apart so that they do not cross each other, thereby smoothing the flow of gas in the first liquid condensation pipe 471. Also, the third pipe 423 and the fourth pipe 424 are regularly arranged and spaced apart so that they do not cross each other, thereby smoothing the flow of gas in the second liquid condensation pipe 472.

[0126] In some embodiments, the dimension of first liquid condensation tube 471 in the third direction, the dimension of second liquid condensation tube 472 in the third direction, the length of first support plate 420 in the third direction, and the length of second support plate 430 in the third direction may be substantially the same. In this way, it is possible to prevent first liquid condensation tube 471 and second liquid condensation tube 472 from exceeding first support plate 420 and second support plate 430, so that first support plate 420 and second support plate 430 can protect first liquid condensation tube 471 and second liquid condensation tube 472, while it is possible to prevent first liquid condensation tube 471 and second liquid condensation tube 472 from being too short, so that gas in second air passage 12 can flow through first liquid condensation tube 471 and second liquid condensation tube 472 for a relatively long time, improving the dehumidification effect of liquid condenser 400.

[0127] In some embodiments, as shown in FIG. subject461 further includes a plurality of third exhaust holes 460. The plurality of third exhaust holes 460 are provided at an end (lower end) of the first tube 491 close to the gas collection tube 480 and an end (lower end) of the third tube 423 close to the gas collection tube 480, respectively. The plurality of third exhaust holes 460 are located on a side (e.g., a rear side) of the first liquid condensation tube 471 or the second liquid condensation tube 472 close to the condenser 300.

[0128] Since the length of first tube 491 is longer than the length of second tube 492 and the length of third tube 423 is longer than the length of fourth tube 424, the amount of gas in first tube 491 and the amount of gas in third tube 423 are relatively large. By providing a plurality of third exhaust holes 460, the gas in the relatively long liquid condensation tubes (e.g., first tube 491 and third tube 423) can be exhausted from the corresponding third exhaust holes 460, improving the blowing efficiency of first tube 491 and third tube 423. In turn, the flow resistance of the gas in first tube 491, second tube 492, third tube 423, and fourth tube 424 can be made substantially the same, thereby increasing the blowing amount of second air passage 12.

[0129] In some embodiments, the corners of the inner walls of the first suction cavity 441 and the second suction cavity 451 may be rounded corners. For example, the cross section of the first suction cavity 441 or the cross section of the second suction cavity 451 is rectangular, and the corners of the rectangle are arc-shaped. For the function and effect of the rounded corner structure, reference may be made to the relevant description above, which will not be repeated here.

[0130] In some embodiments, the cross section of the first liquid condenser tube 471 and the cross section of the second liquid condenser tube 472 may be at least one of circular, elliptical, and teardrop shaped.

[0131] In some embodiments, the first liquid condensation tubes 471 and the second liquid condensation tubes 472 may each be arranged in a row along the third direction. Alternatively, the first liquid condensation tubes 471 may be arranged in a plurality of rows along the first direction, and the second liquid condensation tubes 472 may be arranged in a plurality of rows along the first direction. Also, in the first direction, the first liquid condensation tubes 471 of the plurality of rows of the first liquid condensation tubes 471 may be aligned with each other, and the second liquid condensation tubes 472 of the plurality of rows of the second liquid condensation tubes 472 may be aligned with each other. Alternatively, the first liquid condensation tubes 471 of at least two rows of the plurality of rows of the first liquid condensation tubes 471 may be offset from each other, and the second liquid condensation tubes 472 of at least two rows of the plurality of rows of the second liquid condensation tubes 472 may be offset from each other.

[0132] In some embodiments, the first liquid condenser tube 471 and the second liquid condenser tube 472 may be metal tubes (e.g., copper tubes). A hydrophobic layer is provided on the inner wall of the liquid condenser tube 410. The hydrophobic layer may be a compound coating having hydrophobicity (e.g., fluorosilane polymer). For the function and effect of the hydrophobic layer, reference may be made to the above related description, which will not be repeated here. Of course, the material of the first liquid condenser tube 471 and the second liquid condenser tube 472 may be a material having a good condensation heat exchange coefficient, such as vinylidene fluoride.

[0133] In some embodiments, as shown in FIG. 3 and FIG. 4, the dehumidifier 1 further includes a water collecting section 470 (also called a water tray). The water collecting section 470 is provided in the housing 100 and is located at the bottom of the evaporator 200, the condenser 300, and the liquid condenser 400. The water collecting section 470 is configured to accommodate the condensed water generated by the evaporator 200, the condenser 300, and the liquid condenser 400. In this case, the condensed water on the outer surface of the evaporator 200 and the condensed water in the liquid condenser 400 can drip into the water collecting section 470 in a direction (downward) approaching the water collecting section 470. In this way, the water collecting section 470 can collect the condensed water and prevent the condensed water from flowing to other components of the dehumidifier 1, thereby preventing the condensed water from contaminating other components of the dehumidifier 1. In some embodiments, as shown in FIG. 3, the water collecting section 470 includes a water collecting groove, and the dehumidifier 1 further includes a water storage tank 60. The water collecting groove communicates with a water storage tank 60, which may be located on the side of the water collecting portion 470 away from the liquid condenser 400 (eg, below).
