Industry.I.e. in the present embodiment, which can be the cleaning section of T-shaped structure, and two cleaning mouths share a cleaning section, effectively
Ground improves the practicability of the cleaning section.Certainly, which is also possible to the structure of other shapes.
As shown in figure 3, cleaning section 20 includes operation portion 21, the second channel washer 22 according to another embodiment of the application
With third channel washer 23.The first end of second channel washer 22 is connected with the first end of operation portion 21 with the first end of operation portion 21
It connects.The first end of third channel washer 23 is connected with the second end of operation portion 21, third channel washer 23 and 22 phase of the second channel washer
It is arranged over the ground, operation operation portion 21 can make the second channel washer 22 and third channel washer 23 respectively by the first cleaning mouth 111 and the
The inside that two cleaning mouths 112 enter air duct 10 simultaneously carries out cleaning operation.Setting can further improve the cleaning in this way
The practicability in portion effectively improves the cleaning efficiency of cleaning section.
Further, the length of the second channel washer 22 and third channel washer 23 is greater than or equal to the width of second sidewall 13.
It can guarantee thoroughly to clean the pollutant on the side wall of air duct in this way.
Preferably, at least part of cleaning section 20 is made of metal.
Further, ducting assembly further includes sealing joint strip 30.Sealing joint strip 30 is removable installed at cleaning mouth 11.
Setting in this way so that will be sealed after cleaning after the completion of being cleaned using cleaning section to air duct with sealing joint strip so that
Air channel structure can continue to work normally be not in effectively improved the case where leaking out the air channel structure practicability and can
By property.
Air channel structure in above-described embodiment can be also used for washing machine equipment technical field, i.e., according to the present utility model
On the other hand, a kind of washing-drying integral machine, including ducting assembly are provided, washing-drying integral machine carries out cleaning work for treating cleaning materials
Industry simultaneously can carry out drying operation to the object to be cleaned after cleaning, and ducting assembly is the ducting assembly in above-described embodiment.
Specifically, which is a kind of cleaning device of included cleaning plant.When accumulative one timing of operation of model machine
Between after t or certain frequency n, the air duct of washing drying device can be cleared up manually.This device can extend the service life of drying system, be promoted
Drying performance reduces unit failure rate.The drying experience for promoting user, promotes drying efficiency, reduces customer complaint.Cleaning, drying
Air duct reduces the bacterial number in washing drying device system, and drying mode is more healthy.Improve product competitiveness.
Specifically, after model machine adds up operation certain time t or certain frequency n, the vertical of drying system can be cleared up manually
Pollutant in air duct.
The cleaning device is by horizontal duct, vertical air duct, the composition such as drying blower.Wherein in horizontal duct connection model machine
Thus cylinder, hot wind enter model machine inner cylinder.Vertical air duct connects model machine outer cylinder.A small amount of water, dust, line bits are thus through arranging after condensation
Water pipe enters draining pump, and model machine is discharged.Vertical air duct is cuboid.On the longer inside both sides of cuboid, be arranged Butterworth Hatch and
Two foils, setting high-temperature resistant rubber item seals at Butterworth Hatch.Sheet metal is tightly bonded vertical air duct inner wall.Two metals
Piece forms a U-shaped cleaning section by operation portion.Sheet metal slides U-shaped operation portion when model machine is not run manually, will adhere to
In air duct, the trash line clearup of inner wall is clean.When model machine operation drying, sealed above slideway by rubber strip, vertical air duct is completely close
Envelope, prevents hot wind from leaking out, influences to dry.
Specifically, when cleaning device operates normally, continuous with the time adds up, and line bits can be attached on the inner wall of air duct.
After being spaced certain runing time t or number of run n.User powers off unit.Then the seal rubber of vertical air duct side is opened
U-shaped cleaning plant is inserted into behind vertical air duct and is pushed into air duct bottom along slideway by item.C times repeatedly.After the completion of cleaning, extract out U-shaped clear
Device is managed, sealing rubber strip is covered, unit powers on booting, after running any non-drying mode, can all consider the line cleaned up to be worth doing
Exclude model machine.The length of sheet metal should be equidistant with the most wide of vertical air duct longer side.To guarantee that sheet metal can be cleared up completely
Whole positions in vertical air duct.Two sheet metal equal lengths guarantee that every side in vertical air duct can sufficiently be cleared up.Two
Sheet metal is made up of U-shaped cleaning section operation portion, and U-shaped cleaning plant is inserted by when operation, when not running, U-shaped cleaning dress
Set then in addition preservation.
Cleaning section can be set to the elasticity for having certain, in the case where guaranteeing that slideway or air duct or more width are inconsistent,
Cleaning work can operate normally.
Wherein, the numerical value of runing time t can be adjusted as needed, and the numerical value of number of run n can carry out as needed
Adjustment.The numerical value of clearing times c can be adjusted as needed repeatedly, the thickness of sheet metal, length, width numerical value can basis
It needs to be adjusted, the shape of sheet metal can be adjusted as needed, and shape, size, the material of sealing strip can be as needed
It is adjusted.
Than that described above, it is also necessary to which explanation is " one embodiment " spoken of in the present specification, " another implementation
Example ", " embodiment " etc. refer to that specific features, structure or the feature of embodiment description is combined to be included in the application summary
Property description at least one embodiment in.It is not centainly to refer to the same reality that statement of the same race, which occur, in multiple places in the description
Apply example.Furthermore, it is understood that is advocated is knot when describing a specific features, structure or feature in conjunction with any embodiment
Other embodiments are closed to realize that this feature, structure or feature are also fallen in the scope of the utility model.
In the above-described embodiments, it all emphasizes particularly on different fields to the description of each embodiment, there is no the portion being described in detail in some embodiment
Point, reference can be made to the related descriptions of other embodiments.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
