Embodiment
The utility model is described in detail in shown each embodiment below in conjunction with the accompanying drawings, but it should explanation,
These embodiments are not limitation of the utility model, and those of ordinary skill in the art are according to these embodiment institute works
Energy, method or equivalent transformation or replacement in structure, belong within the scope of protection of the utility model.
As shown in Figure 1, the method for preventing the improper operating of motor for washer of the utility model includes the following steps：
The electric current passed through in S1, pair conducting wire being connected with motor is detected, and has such as detected electric current by then exporting
Detect signal.
Wherein, it is contemplated that when there is short circuit when failure, motor is under the action of the electric current of offer, lasting rotation.Therefore,
In order to be detected to the improper operating condition of motor, the electric current that can pass through in pair conducting wire being connected with motor is examined
Survey, and export detection signal.
Above-mentioned detection signal is exported in the following way：The electric current passed through in pair conducting wire being connected with motor carries out
Detection, has such as detected electric current by exporting corresponding voltage, being amplified to the voltage of output, and by amplified voltage
Exported as detection signal.
S2, receive the detection signal, persistently detects whether halt instruction is issued to control the stopping of the motor.
Wherein, the purpose of step S2 is, judges motor state in which.It is current under the control of instruction normal rotation
When, do not perform subsequent method step.When halt instruction is sent, start to be detected the operating status of motor.The stopping
Instruction is received and performed by the drive circuit of the motor, when above-mentioned drive circuit receives the halt instruction, driving
Circuit is in off state, so as to fulfill the stopping of the motor.
S3, halt instruction has been sent as described in detecting, is judged after time delay, in the conducting wire being connected with motor
Whether electric current is had by such as without electric current by the way that then motor is runs well, and otherwise, motor is improper operating, force disconnect
The power supply of the washing machine.
Wherein, when halt instruction is sent, by time delay, the electric current passed through in the conducting wire being connected with motor should
It is zero.When being in improper operating such as motor, then by halt instruction motor can not be controlled to stop, thus can determine whether the fortune of motor
Whether normal turn state.
Alarm in addition, the step S3 further includes the problem of being in improper operating for motor.Specifically, it is described
Step S3 is further included：When after time delay, having electric current by then carrying out buzzing alarm or audio alert.Alternately, such as
Integrated in washing machine by wireless module, then when after time delay, have electric current by when, send alarm signal to user mobile phone
Breath, so with overcome user not indoors when can not receive buzzing alarm or audio alert the problem of.
Further, when motor is in normal operation, the method for the utility model further include to motor whether by
Normal control is detected.Specifically, the method for the utility model further includes step S4, it can be used for judging that motor is stopping to transport
Whether can normally be restarted after turning, the step S4 includes：
When after time delay, without electric current by persistently detecting whether operation instruction is issued to control the electricity
The rotation of machine, such as in setting time, is received again by the detection signal, then motor is normally controlled, otherwise, motor by it is non-just
Often control.
As shown in Fig. 2, based on the above-mentioned method for preventing the improper operating of motor for washer, the utility model also provides one kind
The system for preventing the improper operating of motor for washer, the system include：Current inductor 10, MCU20, motor-drive circuit 30.
The current inductor 10 is arranged in the guiding being connected with motor, and the current inductor 10 can be used for：
The electric current passed through in pair conducting wire being connected with motor is detected, and detection signal is sent to the MCU20.Preferably,
The current transformer 10 can be mutual inductor current detection sensor.
Further, during output detection signal, pass through in described 10 pairs of conducting wires being connected with motor of current inductor
Electric current is detected, and has such as detected electric current by exporting corresponding voltage, being amplified to the voltage of output, and will amplify
Voltage afterwards is exported to the MCU20 as detection signal.
The MCU20 is used for：The detection signal is received, and continues to detect whether halt instruction is issued with described in control
Motor-drive circuit 30 disconnects, and the halt instruction as described in detecting has been sent, and is judged after time delay, is connected with motor
Conducting wire in whether have electric current by, such as without electric current by, then motor for run well, otherwise, motor is improper operating,
The power supply of total relay 40 of washing machine described in force disconnect.
Further, the motor-drive circuit 30 includes turning off or connecting silicon-controlled.So as to described silicon-controlled
According to the instruction of reception, turn off or turn on, and then rotation to motor and stopping are controlled.
In order to alarm the problem of being in improper operating to motor, the system also includes buzzer or speech play
Circuit.Alternately, the system also wireless communication module, at this time, can be sent out by the wireless communication module to user mobile phone
Send warning message, so with overcome user not indoors when can not receive buzzing alarm or audio alert the problem of.
Further, in order to realize when motor is in normal operation, examined to whether motor is normally controlled
Survey.The MCU20 is additionally operable to：When after time delay, without electric current by, persistently detect operation instruction whether be issued with
Controlling the rotation of the motor, such as in setting time, be received again by the detection signal, then motor is normally controlled, otherwise,
Motor is by improper control.
In conclusion the method for preventing the improper operating of motor for washer of the utility model can be determined that output to motor
Current in wire it is whether normal, when short circuit occurs when failure, may recognize that failure, and send control instruction, cut off the power defeated
Enter, leave the motor off operating, so as to play the role of protection.
