Summary of the invention
The object of the invention aims to provide that a kind of size is little, noise is low, compact conformation, dehumidifier that Energy Efficiency Ratio is high, to overcome weak point of the prior art.
Dehumidifier provided by the invention; Comprise compressor, heat exchanger, wind wheel, motor and inlet and outlet in the casing, compressor is positioned at the dehumidifier bottom, and wind wheel comprises wind wheel and following wind wheel; Motor is positioned in the middle of wind wheel and the following wind wheel; Heat exchanger is positioned at the wind wheel outside, and heat exchanger comprises the evaporimeter and inboard condenser in the outside, and inlet and outlet is the evaporimeter outside on casing.
Preferably, said evaporimeter comprises evaporimeter and following evaporimeter, and affiliated condenser comprises condenser and following condenser.
Alternatively, said wind wheel is axial-flow windwheel, centrifugal wind wheel or tubular wine wheel.
Alternatively, said evaporimeter and condenser are curved row's structure, and wherein, the heat exchanger of curved row's structure is L type, U type, G type, arc or rolls over shape more.
Alternatively, the said wind wheel of going up can have same type and specification with following wind wheel, also can have dissimilar and specification, and outside evaporimeter and interior side condenser can have same types, size, specification, also can have different types, size, specification.
Alternatively, said evaporimeter and condenser are fin circular pipe type heat exchanger, parallel-flow heat exchanger and/or fin ellipse tube type heat exchanger.When left heat exchanger and right heat exchanger are fin circular pipe type heat exchanger; Can have that identical caliber, row number, fin crack that form, sheet are wide, stream etc.; Can have also that different tube diameters, row number, fin crack that form, sheet are wide, stream etc., can carry out flexible combination as required.When left heat exchanger can have identical flat tube parameter (width, number of aperture, length), fin form, flow process number etc. with right heat exchanger during for parallel-flow heat exchanger; Also can have different flat tube parameter (width, number of aperture, length), fin form, flow process number etc., can select for use flexibly as required.When left heat exchanger and right heat exchanger are fin ellipse tube type heat exchanger; Can have that identical cross sectional shape, fin crack that form, sheet are wide, stream etc.; Can have also that different cross section shape, fin crack that form, sheet are wide, stream etc., can carry out flexible combination as required.
The beneficial effect of the invention
The present invention adopts the structure of the two up and down wind wheels of single driven by motor, under the situation of the fuselage size that does not change dehumidifier, has increased heat exchange area and air output, has improved the heat exchanger heat exchange efficiency, promotes the product Energy Efficiency Ratio significantly, has reduced noise.And it is simple and compact for structure, has both artistic and practical and the small and exquisite characteristics of profile.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Referring to Fig. 2, this dehumidifier comprises compressor 7, heat exchanger, wind wheel, motor 5 and inlet and outlet in the casing, adopts single driven by motor structure of two different wind wheels up and down.Wind wheel comprises wind wheel 4 and following wind wheel 6, and motor 5 is positioned in the middle of wind wheel 4 and the following wind wheel 6, last wind wheel 4 and following wind wheel 6 shared motors; The last condenser 21 and the following condenser 22 of last evaporimeter 11 outside heat exchanger comprises and following evaporimeter 12, inboard.Compressor 7 is positioned at the dehumidifier bottom.Following evaporimeter 12 is fixed on the support 3 with following condenser 22.
Going up wind wheel 4 in the present embodiment is tubular wine wheel, and following wind wheel 6 is a centrifugal wind wheel, adopts the air draught mode to carry out heat exchange, and inlet and outlet is the outside of last evaporimeter 11 and following evaporimeter 12.
External heat exchanger is an absolute construction in the present embodiment.Evaporimeter 11 and following evaporimeter 12 on the outside, condenser 21 is arranged structure with following condenser 22 for bending on the inboard, and shown in accompanying drawing 4, the heat exchanger of curved row's structure is the U type, and arrow is the air intake direction among the figure.Evaporimeter and condenser are fin circular pipe type heat exchanger.
