Embodiment three
As shown in figs9-12, it is described in further detail on the basis of embodiment one and two in the present embodiment：
Drying unit includes drying module 46 and the exhaust air flue 40 and return airway 41 that are respectively communicated with drying module 46,
The exhaust air flue 40, return airway 41 connect respectively with for holding the process chamber of object to be dried, the baking of drying module 46
Dry-air blast enters through exhaust air flue 40 after object to be dried is heated in process chamber drying discharges process chamber through return airway 41；The outlet air wind
The distinguished and admirable flux of drying is more than the distinguished and admirable flux of drying in 41 unit interval of return airway in 40 unit interval of road.
Drying wind is conveyed into process chamber by drying module, realizes and is dried to handling indoor object to be dried, led to
Crossing structure design makes the distinguished and admirable flux of drying in 40 unit interval of exhaust air flue distinguished and admirable more than drying in 41 unit interval of return airway
Flux, the air quantity for making the indoor drying wind of processing is sufficient, and on the other hand, drying wind is long in the indoor retention time of processing, drying
The enough moisture taken away to greatest extent on clothing of wind energy, improves the utilization rate of drying wind, realizes better drying effect.
The exhaust air flue 40 and return airway 41 are being respectively provided with section minimum position on drying wind direction, described
The sectional area at 40 upper section minimum position of exhaust air flue is more than the sectional area at the 41 upper section minimum position of return airway.
The 41 upper section minimum position of return airway is more than by the sectional area at 40 upper section minimum position of exhaust air flue
Sectional area, realize that it is distinguished and admirable to be more than drying in 41 unit interval of return airway for the distinguished and admirable flux of drying in 40 unit interval of exhaust air flue
Flux, come into full contact with indoor drying wind and the article to be dried of processing, mass transfer, heat transfer, improve baking of the drying unit to clothing
Dry efficiency.
The section ratio at 40 upper section minimum position of exhaust air flue and the 41 upper section minimum position of return airway is 1.5-
1.9：1.The air output of exhaust air flue 40 is different with the return air amount of return airway, and the drying effect for drying clothing to be dried is different,
The air output of exhaust air flue 40 is big, can improve the drying efficiency and drying effect of article to be dried, but if air-out volume
It is mismatched with return air air quantity, if air output is excessive, be easy to cause the serious waste of electric resources, if air output is too small, can reduce
Drying efficiency, poor user experience.When the section at 40 upper section minimum position of exhaust air flue and 41 upper section of return airway most
When the ratio between the section at small position is 1.5-1.9, resource and the balance of drying efficiency are realized, the maximum limit under less resource output
The drying article to be dried of degree, moreover, 40 section of exhaust air flue is big, drying wind will not be expelled directly out without mass transfer and heat transfer,
Drying wind is more easy to disperse in process chamber, big with the contact area of article to be dried, improves the drying efficiency of clothing to be dried, and
And clothing is more fluffy.
Further, the section at 40 upper section minimum position of exhaust air flue and the 41 upper section minimum position of return airway
The ratio between section be 1.7：1.
Scheme one, the exhaust air flue 40 and return airway 41 are the constant air duct in section, the exhaust air flue 40
Section is more than the section of return airway 41.Since the section of exhaust air flue 40 is more than the section of return airway, it is more than air output
Return air amount handles indoor drying wind energy amount height, good drying effect.
Scheme two, exhaust air flue 40 and/or 41 part of return airway are inside contracted to air duct into formation docking portion, the docking portion
Section it is minimum, the docking portion section of the exhaust air flue 40 is more than 41 docking portion section of return airway.
Such as, the air duct identical with the use of return airway 41 section of exhaust air flue 40, still, the setting contracting in return airway 41
Into portion, reduce the internal diameter at the position, realize that the air-out volume in the unit interval is more than return air air quantity, improve the drying of washing machine
Effect and drying efficiency.
Wherein, it can also be and be respectively provided with docking portion in exhaust air flue 40 and return airway 41, make the contracting of exhaust air flue 40
Into portion section be more than return airway 41 docking portion section.
Further, exhaust air flue 40 and the communication port of process chamber are air outlet 42, and the air outlet 42 is exhaust air flue
The communication port of the position of section minimum on 40, return airway 41 and process chamber is return air inlet 43, and the return air inlet 43 is return air
The position of section minimum on air duct 41, the section of the air outlet 42 are more than the section of return air inlet 43.Due to 42 He of air outlet
Return air inlet 43 is connect with process chamber, and 42 section of air outlet is more than return air inlet section, and drying wind is after the discharge of air outlet 42 from
Room is managed, since air outlet 42 is larger, the distinguished and admirable flux of drying is more than 41 unit interval of return airway in 40 unit interval of exhaust air flue
The interior distinguished and admirable flux of drying makes the indoor drying wind air inlet of processing be more than air draft, drying wind is made to be come into full contact with article to be washed, is realized
Preferable drying effect；On the other hand, the air outlet 42 of drying unit is big, wind is made to be convenient for dispersion when entering back into process chamber, with treating
The contact surface of drying article is big, improves drying effect.
Further, the section ratio of the air outlet 42 and return air inlet 43 is 1.5-1.9：1, realize resource consumption and drying
The balance of efficiency dries article to be dried, moreover, the air outlet of drying unit is cut to greatest extent under less resource output
Face is big, and drying wind is more easy to disperse in process chamber, big with the contact area of article to be dried, improves the drying effect of clothing to be dried
Rate, and clothing is more fluffy.
The section ratio preferably 1.7 of the air outlet 42 and return air inlet 43:1, at this moment, the consumption of electric energy etc. and heat
Utilization ratio reaches certain balance, and in the consumption such as minimum electric energy output, it is best, most fast that drying article is treated in realization
Drying.
Example IV
As described and depicted in figs. 9-13, the present embodiment is the further restriction to embodiment two, and drying unit further includes housing 47, institute
It states exhaust air flue 40 and return airway 41 is set in housing 47,42 one end of air outlet of the exhaust air flue 40 and return airway
41 43 one end of return air inlet is pierced by housing 47, for being connected with process chamber.The exhaust air flue 40 and return airway 41 are set to
In housing 47, on the one hand, housing 47 can have protective effect, on the other hand, save exhaust air flue 40 and return airway 41
Space, and prevent exhaust air flue and return airway 41 from winding damage etc..
