That is, there are various arrangements of the water condensation pipes 410 of the upper part 401 and the water condensation pipes 410 of the lower part 403, for example, the distance between the water condensation pipes 410 of the upper part 401 is the same as that between the water condensation pipes 410 of the lower part 403, and the number of the water condensation pipes 410 of the upper part 401 is the same as that of the water condensation pipes 410 of the lower part 403; or the distance between the water condensation pipes 410 of the upper part 401 and the distance between the water condensation pipes 410 of the lower part 403 are the same, and the number of the water condensation pipes 410 of the upper part 401 is different from that of the water condensation pipes 410 of the lower part 403; or, the distance between the water condensation pipes 410 of the upper part 401 and the distance between the water condensation pipes 410 of the lower part 403 are different, and the number of the water condensation pipes 410 of the upper part 401 is the same as that of the water condensation pipes 410 of the lower part 403.

Further, as shown in fig. 5 and 6, the side of the water condensation pipe 410 of the middle portion 402 facing the evaporator 200 exceeds the side of the water condensation pipe 410 of the upper portion 401 facing the evaporator 200 and the side of the water condensation pipe 410 of the lower portion 403 facing the evaporator 200. That is to say, the extension length of the water condensation pipe 410 of the middle part 402 on the first air flue is greater than the extension length of the water condensation pipe 410 of the upper part 401 on the first air flue and the extension length of the water condensation pipe 410 of the lower part 403 on the first air flue, thus, the contact area between the water condensation pipe 410 of the middle part 402 and the low-temperature gas in the first air flue is larger, the heat exchange time is longer, the heat exchange effect is better, the dehumidification effect of the dehumidifier 1 is further improved, and the structure of the water condensation pipe 410 of the middle part 402 in the up-down direction is hardly changed, and meanwhile, the flow wind resistance of the air flow in the first air flue is not additionally increased, and the structure setting is more reasonable.

In some embodiments of the present invention, as shown in fig. 3-7, the water condensation pipe 410 has an air inlet end 411 and an air outlet end 412, the gas in the second air channel flows into the water condensation pipe 410 from the air inlet end 411 and flows out of the water condensation pipe 410 from the air outlet end 412, and the gas flowing out of the second air channel from the air outlet end 412 is mixed with the gas in the first air channel in front of the condenser 300.

The front of the condenser 300 refers to the front side of the condenser 300 in the direction along the air flow of the first air duct, and the air in the first air duct first flows through the front of the condenser 300.

And, the air inlet end 411 of the water condensation pipe 410 is used for allowing indoor air to enter the water condensation pipe 410, the air outlet end 412 enables the air in the water condensation pipe 410 and the gas in the first air channel to be discharged to the condenser 300 together after heat exchange, and the condenser 300 and the mixed gas exchange heat to enable the gas in the first air channel and the second air channel to form medium-temperature dry gas and discharge the gas to the indoor.

For example, the axial one end of water condensation pipe 410 can be located to the air inlet end 411 of water condensation pipe 410, and the axial other end of water condensation pipe 410 is located to the air outlet end 412, and like this, the distance of water condensation pipe 410's air inlet end 411 and air outlet end 412 can maximize, indoor air is longer in the flow path of water condensation pipe 410, and the flow time is also longer, so that the air in the water condensation pipe 410 can give and carry out abundant heat transfer with the gas in the first air flue, thereby make the abundant condensation of air in the water condensation pipe 410 form the comdenstion water, further improve dehumidifier 1's dehumidification efficiency.

In some embodiments of the present invention, as shown in fig. 9 and 10, a plurality of exhaust holes 450 are formed in one side of each water condensation pipe 410 facing the condenser 300, and the plurality of exhaust holes 450 are uniformly arranged at intervals along the length direction of the water condensation pipe 410. Like this, under the gaseous cooling dehumidification effect in guaranteeing condenser pipe 410 internal gas by first wind channel, increase condenser pipe 410 outflow gaseous and condenser 300's heat exchange area, in addition, this design can also increase the fan and roll up the gaseous flow in the absorption condenser pipe 410 to increase the amount of wind through condenser 300, further improvement condenser 300's heat transfer effect.

Moreover, the number of the exhaust holes 450 is not more than 5, the distance between each exhaust hole 450 and the air inlet end 411 is greater than the distance between each exhaust hole 450 and the air outlet end 412, the distance between any two exhaust holes 450 of the exhaust holes 450 is less than one third of the length of the water condensation pipe 410, and the aperture of each exhaust hole 450 is less than the pipe diameter of the water condensation pipe 410.

Therefore, the gas in the water condensation pipe 410 and the gas in the first air channel can be ensured to have sufficient heat exchange time, so that the gas in the water condensation pipe 410 can be sufficiently cooled and dehumidified, and condensed water is condensed out.

In some embodiments of the present invention, as shown in fig. 3 and 7, the water condensation pipe 410 has an air inlet end 411 and an air outlet end 412, the gas in the second air channel flows into the water condensation pipe 410 from the air inlet end 411 and flows out of the water condensation pipe 410 from the air outlet end 412, and the water condensation pipe 410 is inclined downwards gradually in the direction from the air inlet end 411 to the air outlet end 412.

In other words, the height of the air inlet end 411 of each water condensation pipe 410 is higher than that of the air outlet end 412, so that condensed water in the water condensation pipe 410 can flow rapidly under the influence of gravity, accumulation of the condensed water in the water condensation pipe 410 is avoided, and the condensed water can be discharged rapidly.

And, the slope of water condensing pipe 410 is greater than 3%, that is to say, the ratio of the size of the projection of water condensing pipe 410 on the vertical direction to the size of the projection of water condensing pipe 410 on the horizontal direction is greater than 3%, and like this, can guarantee that the slope of water condensing pipe 410 is great, and that is to say, water condensing pipe 410 is great for the inclination of horizontal plane, and the comdenstion water in water condensing pipe 410 can flow fast under the influence of gravity, avoids the comdenstion water in water condensing pipe 410 to pile up, so that the comdenstion water can be discharged fast.

Other constructions and operations of the dehumidifier 1 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.

The dehumidifier 1 in the present application performs a refrigeration cycle of the dehumidifier 1 by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the ambient environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve, and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. Throughout the cycle, the dehumidifier 1 can regulate the temperature and humidity of the indoor space.
