Controller 4 is connected, and by 4 programme-control of computerized version controller, computer board controller 4 is equipped with special the power on/off of Electromagnetic Control bolt
" cylinder cleaning " program of low speed rotating cylinder can control cleaning device to complete cleaning.
Using the washing machine of above-mentioned outer barrel cleaning device, as shown in Figure 1, including babinet 1, outer barrel 2, inner cylinder 3, control and driving
Dynamic device, the outer barrel 2 are arranged in the babinet 1, are equipped with the outer barrel cleaning device.
Its corresponding outer barrel cleaning method, comprises the following steps：
（1）The poke rod of changement（It is Electromagnetic Control bolt first 74 in the present embodiment）It stretches out；Inner cylinder 3 with respect to outer barrel 2 to
One side direction rotates, and poke rod passes through toggle switch 63, and toggle switch 63 is made to commutate and is locked, while shaft 65 is driven to make cleaning
Device rotates and from heavily fortified point in inner cylinder groove 31, and washer is contacted with 2 inner wall of outer barrel；
（2）The poke rod of changement is retracted, and inner cylinder 3 is reversely rotated with respect to outer barrel 2, and washer is driven to realize in outer barrel
Wall cleans；
（3）It after the completion of cleaning, rotates and stops, the poke rod of changement stretches out, and inner cylinder 3 is with respect to the reversely rotation again of outer barrel 2
Turn, poke rod passes through toggle switch 63, and toggle switch 63 is made to commutate and is locked, while shaft 65 is driven to rotate back into washer
Original state.
The step is gathered（2）With（3）In, inner cylinder 3 reversely rotates a week and a half.
More specifically process is referring to Fig. 7 to 12, and during Normal Wash state, toggle switch 63 rotates to the leftmost side, brush holder support
61 and bristle 62 lie down in groove 31, Electromagnetic Control croze 75 and Electromagnetic Control bolt it is first 74 reset be contracted in Electromagnetic Control bolt seat
In 71.
When needing to open cleaning device 6, the energization of Electromagnetic Control bolt acts, Electromagnetic Control croze 75 and Electromagnetic Control bolt first 74
It is stretched out from Electromagnetic Control bolt seat 71, inner cylinder 3 rotates counterclockwise to few 1 circle, preferred 1 circle half of rotation, when toggle switch 63 is encountered
It after Electromagnetic Control bolt first 74, is struck and rotates clockwise 90 degree, self-locking is realized by self-locking convex ball 66 and limiting slot 68 afterwards.
Brush holder support 61 follows toggle switch 63 to be rotated by 90 °, and from lying down, laid-flat status becomes vertical state.When toggle switch 63 rotates to 90
After degree, inner cylinder 3 further rotates, Electromagnetic Control bolt first 74 because be subject to axis make when increasing to pressure adjustable spring 1 shrink,
So that Electromagnetic Control bolt first 74 is slipped over from 63 upper end of toggle switch.For inner cylinder 3 counterclockwise after 1 circle half of rotation, Electromagnetic Control bolt 7 is disconnected
Reset, Electromagnetic Control croze 75 and Electromagnetic Control bolt first 74 are reset in Electromagnetic Control bolt seat 71.With the rotating brush of inner cylinder 3
Hair 62 constantly scrubs outer tube inner wall, realizes the cleaning to outer tube inner wall.
The closing process of cleaning device 6 is similar with opening process, and simply 3 direction of rotation of inner cylinder is opposite.It needs to close and clean
During device 6, Electromagnetic Control bolt energization action, Electromagnetic Control croze 75 and Electromagnetic Control bolt first 74 are stretched from Electromagnetic Control bolt seat 71
Go out, inner cylinder 3 rotates clockwise at least 1 circle, preferred 1 circle half of rotation, when toggle switch 63 encounter Electromagnetic Control bolt it is first 74 after, quilt
It stirs and is rotated by 90 ° counterclockwise, self-locking is realized by self-locking convex ball 66 and limiting slot 68 afterwards.Brush holder support 61 follows poke rod 63
It is rotated by 90 °, state of couching is become from vertical state, realizes the closing of cleaning device 6.After toggle switch 63 rotates to 90 degree,
Inner cylinder 3 further rotates, and Electromagnetic Control bolt first 74 shrinks adjustable spring 1 due to the axial compressive force increase being subject to so that electricity
Magnetic control bolt first 74 is slipped over from 63 upper end of toggle switch.After inner cylinder 3 rotates clockwise 1 circle half, the power-off of Electromagnetic Control bolt 7 is multiple
Position, Electromagnetic Control bolt first 74 are reset in Electromagnetic Control bolt seat 71.
Using the washing machine with the outer barrel cleaning device, in Normal Wash clothing, cleaning device, which is in, closes shape
State, cleaning device can be effectively protected；When needing to carry out cylinder cleaning, washing machine can automatically turn on cleaning device and go forward side by side
A small amount of tap water cleans washing machine outer tube inner wall by inner cylinder rotating, and after cleaning, washing machine is just automatically closed
Washer.
User can periodically carry out cylinder cleaning according to actual conditions, and without doing washing every time when all carries out cylinder cleaning, from
And extend the service life of cleaning device.
During Normal Wash clothing state, toggle switch rotates to the leftmost side, and brush body and bristle lie down in groove, electromagnetism control
Bolt head reset processed is contracted in Electromagnetic Control bolt seat.
The present invention axially sets groove by side outer tube along barrel, and washer is arranged on by shaft described recessed
In slot, washer is made to lie down when not used in groove, when cleaning outer tube inner wall by rotating to be erected in around or with shaft
Groove is simultaneously contacted with outer tube inner wall to clean outer tube inner wall, and from without cleaning outer tube inner wall every time when is all manually installed and dismounting
Cleaning device；By setting the Electromagnetic Control bolt controlled by computer board controller on outer barrel, opened using Electromagnetic Control bolt
With close washer, so as to improve the clean the degree of automation of cylinder.
The present invention solves the problems, such as existing external cylinder of drum-type washing machine cleaning device using trouble or easy to wear, clear with cylinder
Clean effect is good and the advantages of water-saving and electricity-saving, easy to use, high degree of automation.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
