Workflow of the invention is as follows:
In the present invention, start button 8 is separately provided in washing machine self-cleaning function, is connected positioned at washing machine microcontroller 16
On control panel.When self-stripping unit does not work, sliding block 5 and annular cleaning brush (being made of two semi-circular cleaning brush 9) are located at
The top of accommodating chamber.Start button 8 is pressed, microcontroller 16 controls two stepper motors 1 while carrying out equidirectional at this time
Rotation, two motors drive the constant speed rotation of two progress same directions of lead screws 3 respectively, and You Lianggen lead screw 3 drives two sliding blocks 5
The downward translation for carrying out identical speed opens simultaneously water feeding and draining device to 10 water supply of inner cylinder, and starts the impeller connected with impeller
Motor 12 drives impeller and water rotation, water in inner cylinder 10 to enter accommodating chamber by the through-hole on inner cylinder 10, if thinking cleaning
Appropriate cleaning solution can be more thoroughly poured into washing machine.When sliding block 5 reaches the bottom of accommodating chamber 14, microcontroller 16 is sent out
Instruction makes two stepping motors 1 while rotating backward out, so that two sliding blocks 5 move upwards Ring form brush 9 is driven to continue simultaneously
Cleaning, while brush immerses in flowing water in bottom, has a cleaning effect to brush itself.When brush moves upward to top
When portion, a duty cycle terminates, and starts next duty cycle, circularly carries out, it is primary to preset good berth
Need device circulation several times, complete cleaning rear slider 5 and brush 9 come back to top, close stepping motor 1 and with impeller electricity
Machine 12, while inner tank of washing machine 10 is discharged in water, complete cleaning.The synchronously control of microcontroller 16, it is characterised in that according to
For the default rotation Lap Time of stroke length in algorithm routine, the circle number needed for one of lead screw 3 is first completed makes its sliding block 5 reach bottom
When portion but another sliding block 5 lag, the halt instruction of the lead screw 3 of circle number is first completed in microcontroller 16 publications, so that arriving first
The sliding block 5 reached is parked in bottom waiting, issues toggling command again when circle number needed for meeting two lead screws 3 and all reaching, reaches starting point
Shi Tongli, i.e. every half period are once adjusted in synchronism.
In the present invention, microcontroller can realize the control such as AT89S52 single-chip microcontroller of stepper motor, the microcontroller
It can be communicated with the central control system of washing machine, when self-cleaning function is opened, it is ultraviolet that microcontroller provides signal unlatching
Line sterilamp, and the rotation of impeller motor, open and close of water inlet and clear are realized by the central control system of washing machine
