Abstract
The present invention discloses foreign matter cognitive method in a kind of drainage pump of washing machine and breaks away from method, exception is judged whether by the current rotating speed of motor, gone out again by voltage control time more than threshold decision there are foreign matter, so as to detect not discharging with the presence or absence of foreign matter in draining pump automatically.When thinking in draining pump there are after foreign matter, then the continuous startup direction for changing drain pump impeller several times is to discharge foreign matter.
Description
Technical field
The invention belongs to washing of drum type washing machine control field.
Background technology
The draining pump motor used in the washing machine of the prior art is exchange driving, in draining, if there is foreign matter certainly
When discharging in washing tube and block draining pump inner impeller, then when forced rotating impeller and foreign matter cannot discharge, meeting
The rotation for motor occur is got stuck, and impeller idle running motor temperature rises, and is burnt more than protection temperature.
Therefore, it is necessary to a kind of new technical solution is to solve the above problems.
The content of the invention
Goal of the invention：Foreign matter cognitive method in a kind of drainage pump of washing machine is provided, if having in draining pump can not discharge it is different
Thing can detect automatically.
The present invention also provides a kind of foreign matter to break away from method, if draining pump detects that there are foreign matter to be automatically drained out.
Technical solution：To reach above-mentioned purpose, foreign matter cognitive method can use following skill in drainage pump of washing machine of the present invention
Art scheme：
Foreign matter cognitive method, comprises the following steps in a kind of drainage pump of washing machine：
(1), the rotary speed threshold value of draining pump motor and the voltage control time threshold value of draining pump motor are set；
(2) if, the current rotating speed of draining pump motor be less than rotary speed threshold value, the current voltage control of detection draining pump motor
Time；
(3) if, the current voltage control time of draining pump motor be more than voltage control time threshold value, then it is assumed that in draining pump
There are foreign matter.
Beneficial effect：
Exception is judged whether by the current rotating speed of motor, then presence is gone out more than threshold decision by voltage control time
Foreign matter, so as to detect not discharging with the presence or absence of foreign matter in draining pump automatically.
Foreign matter is broken away from method and can be adopted the following technical scheme that in drainage pump of washing machine provided by the invention：
When thinking in draining pump there are after foreign matter, then it is continuous change drain pump impeller several times startup direction it is different to discharge
Thing.
Beneficial effect：
Being capable of automatically discharging foreign matters by the startup direction for continuously changing drain pump impeller several times.
Embodiment
The present invention discloses foreign matter cognitive method in a kind of drainage pump of washing machine and breaks away from method, including former and later two parts,
First determine whether in draining pump with the presence or absence of the foreign matter that can not be discharged；Then by the foreign matter perceived again by breaking away from method discharge row
Water pump.
Foreign matter cognitive method comprises the following steps in drainage pump of washing machine：
(1), the rotary speed threshold value of draining pump motor and the voltage control time threshold value of draining pump motor are set.The rotary speed threshold value
It is different with the setting in rotary drum washing machine in barrel roll laundry machine.When washing machine is barrel roll laundry machine, rotary speed threshold value is 500 revs/min
Clock.And washing machine is when being rotary drum washing machine, rotary speed threshold value is 1000 revs/min.
(2) if, the current rotating speed of draining pump motor be less than rotary speed threshold value, the current voltage control of detection draining pump motor
Time；
(3) if, the current voltage control time of draining pump motor be more than voltage control time threshold value, then it is assumed that in draining pump
There are foreign matter.And in order to avoid maloperation, current voltage control time are more than voltage control time threshold value duplicate acknowledgment 2 times, when
2 times current voltage control time is more than voltage control time threshold value, that is, thinks that there are foreign matter in draining pump.
The method of breaking away from is, when thinking in draining pump there are after foreign matter, then the continuous startup for changing drain pump impeller several times
Direction is to discharge foreign matter.The startup direction of continuous 6 changes drain pump impeller, changes the direction time for 2 seconds every time.
In addition, the concrete methods of realizing and approach of the present invention are very much, the above is only the preferred embodiment of the present invention.
It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, it can also do
Go out some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.What is be not known in the present embodiment is each
The available prior art of part is realized.
