Specific embodiment

1 to 6 pair of the embodiments of the present invention elaborates with reference to the accompanying drawing.

Duct humidifier, including the cold end air duct 1 with dehumidification by condensation function and with the hot end wind of heating and dehumidification function Road 2, the cold end air duct 1 are fixed on 2 left or right side of hot end air duct, the bottom connection in cold end air duct 1 and hot end air duct 2, Can the blower 3 of inside exhausting be mounted in the bottom that be connected to hot end air duct 2 of cold end air duct 1, by outside air feeding 1 He of cold end air duct It is discharged after dehumidifying in hot end air duct 2.

As shown, outside air, is pumped by duct humidifier by blower 3, into the air in cold end air duct 1, cold End carries out dehumidification by condensation in air duct 1, is discharged after becoming dry cold air, into the air in hot end air duct 2, in hot end air duct 1 In carry out heat absorption drying, be discharged after becoming dry hot-air, air is after duct humidifier dehumidifies, then is expelled back into outside air In, realize the function that removal moisture drying is carried out to outside air.

Wherein, the cold end air duct 1 includes backboard 11, and inside is provided with the sheet metal component 12 in air duct and in sheet metal component 12 Small radiator 13, the hot end air duct 2 include shell 21 and the big radiator 22 in shell 21, the shell 21 It is fixed with sheet metal component 12, thermoelectric (al) cooler A, the chill surface of thermoelectric cold foot device A are housed between small radiator 13 and big radiator 22 It is contacted with small radiator 13, heating face is contacted with big radiator 22, and blower 3 is mounted in the bottom of shell 21, is provided on sheet metal component 12 12.2 are exported with the air inlet 12.1 of 21 connection of shell and the cold wind being connected to outside air, is provided with hot-blast outlet at the top of shell 21 21.1, the air that blower 3 is pumped into, a part enters in cold end air duct 1 and enters dehumidification by condensation in sheet metal component 12 through air inlet 12.1 By 12.2 discharge of cold wind outlet, another part enters in hot end air duct 2 after the heat absorption of big radiator 22 is dry by hot-blast outlet 21.1 discharges.

The sheet metal component 12 includes that surrounding has the quadro frame 12.3 of outward flanging, is fixed on quadro frame 12.3 Condensing chamber 12.4 and fixed outlet air chamber 12.5 is bonded with condensing chamber 12.4, backboard 11 is fixed on quadro frame 12.3 On quadro frame 12.3 had into the one side closed of outward flanging, small radiator 13 is in the condensing chamber 12.4, air inlet 12.1 are provided on condensing chamber 12.4, and cold wind outlet 12.2 is provided on the top surface of outlet air chamber 12.5, condensing chamber 12.4 Passed through air port 12.6 between outlet air chamber 12.5 to be connected to.

It can be seen in the drawings that cold end air duct 1 is located at the left side in hot end air duct 2, due to the chill surface of thermoelectric (al) cooler A It is contacted with small scattered device 13, reduces the temperature in condensing chamber 12.4, heat face is contacted with big radiator 22, makes big radiator 22 The temperature of side rises, and when blower 3 starts, an air flows to big radiator 22, and drying of absorbing heat in big radiator 22 becomes Hot-air is discharged from hot-blast outlet 21.1；Another air stream between backboard 11 and sheet metal component 12, by air inlet 12.1 into Enter into condensing chamber 12.4, since temperature is lower in condensing chamber 12.4, humid air condenses in condensing chamber 12.4, Steam is discharged after condensing in 12.4 inner wall of condensing chamber, and wet air condensation becomes dry air after drying, from condensing chamber 12.4 In flow in wind chamber 12.5, from cold wind outlet 12.2 in be discharged.

Wherein, the air port 12.6 of crossing is provided on the face that condensing chamber 12.4 and outlet air chamber 12.5 fit, and The place height of air inlet product 12.1 was higher than the place height in air port 12.6, and air inlet 12.1 is located at the top surface of condensing chamber 12.4 On, air port 12.6 is crossed close to the bottom of condensing chamber 12.4.From fig. 6 it can be seen that a part of outside air enters from bottom When, it flows upwardly between backboard 11 and sheet metal component 12, reaches air inlet 12.1 and enter in condensing chamber 12.4, by air inlet 12.1 12.4 top that condensing chamber is arranged in is being condensed in order to which the air entered in condensing chamber 12.4 can move from the top down Be fully condensed in face room 12.4, the aqueous vapor in air coagulated completely during moving from the top down it is clean, later again by leaning on The air port 12.6 of crossing of nearly 12.4 bottom of condensing chamber flows into outlet air chamber 12.5, is finally discharged from cold wind outlet 12.2 upwards .Wherein the place height of air inlet 12.1 necessarily was greater than the place height in air port 12.6, be guarantee for air air into After entering condensing chamber 12.4, it will form flowing from top to bottom, rather than directly flow into condensing chamber from air port 12.6 excessively 12.4, humid air has the process of dehumidification by condensation in condensing chamber 12.4, and condensing chamber 12.4 is arranged in air inlet 12.1 On top surface, crosses air port 12.6 and be disposed in proximity to 12.4 bottom of condensing chamber, even if the displacement that humid air flows in condensing chamber Longer, the flowing space is bigger, can be fully condensed dehumidifying, improves dehumidifying reliability.

Wherein, the bottom of the condensing chamber 12.4 is water collecting funnel 12.7, the bottom end of the water collecting funnel 12.7 Collector pipe 12.8 is connected, and collector pipe 12.8 is stretched out from shell 21, the extension end of collector pipe 12.8 connects tapped water pipe Connector 12.9.Leak 12.7 of catchmenting is for collecting the condensed water become after wet air condensation, and condensed water is from water collecting funnel 12.7 In flow in collector pipe 12.8 and be discharged.Collector pipe 12.8 extension end connection water pipe head 12.9 with externally threaded draining Pipe connection, it is ensured that condensed water will not drain into air, influence air humidity again, and dehumidifying reliability is higher.

Wherein, the small radiator 13 and it is big dissipate to hold heat insulating mattress 4 is accompanied between device 22, it is heat-insulated between the two, The mounting hole for placing thermoelectric (al) cooler A, small radiator 13 and big radiator 22 and thermoelectricity are provided among the heat insulating mattress 4 Thermal conductive silicon is coated on the face of cooler A contact to refer to, is improved between thermoelectric (al) cooler A and small radiator 13 and big radiator 22 Heat transfer efficiency, to improve dehumidification efficiency.

Wherein, the small radiator 13 and big radiator 22 are fin type radiator, the fin court of small radiator 13 To 11 side of backboard, the fin of big radiator 22 is towards 3 side of blower.Fin type radiator structure is simple, is easily installed, and leads Good in thermal property, high-efficient, the fin of small radiator 13 guarantees that small radiator 13 is absorbing thermoelectric (al) cooler towards 11 side of backboard It after the refrigerating capacity of A chill surface, is transmitted to condensing chamber, the constant temperature of condensing chamber 24.1 reduces.The fin of big radiator 22 Direction towards 3 side of blower, i.e., downwards heat dissipation, guarantee big radiator 22 after absorbing the heating capacity in thermoelectric (al) cooler A, to Under distribute, when air is upwardly close to big radiator 22, can sufficiently absorb heat drying in big 22 bottom of radiator, improving dehumidifying can By property, and the exothermic temperature opposing floor portion at 22 top of big radiator is lower, also can avoid the air that hot air outlet 21.1 is discharged Temperature is excessively high, causes to damage to external equipment.

Wherein, there is thermal insulation layer on the medial surface of the backboard 11, avoid generating condensation on backboard.The cold wind goes out Mouth 12.2 is oblong openings, and hot-blast outlet 21.1 is the multiple kidney slots being provided on 21 top surface of shell, avoids hot-air quilt Concentrate discharge.The area for changing cold wind outlet 12.2 and hot-blast outlet 21.1, is adjusted cold air and hot end wind in cold end air duct 1 The discharge rate of hot-air in road 2 adjusts the air sendout in cold end air duct 1 and hot end air duct 2.

Utility model has the advantages that
