The washing machine that the present invention is provided includes safety detecting system, and safety detecting system includes controller, washed for detection
Whether the detecting module and alarm module (below have specific introduction) of being are had in clothing machine.As shown in figure 1, what the present invention was provided
Washing machine safety detection method comprises the following steps:
Step S1:When washing machine is shutdown or holding state, step S2 is performed;
When washing machine is running status, step S3 is performed.
Under the shutdown or holding state, washing machine switches on power, but does not run.Wherein, off-mode is to do washing
Machine switches on power, but is not turned on;Holding state, is that washing machine is opened, but do not run.
In step s 2, safety detecting system self-powered, the detecting module work of safety detecting system, controller is in and closes
Closed state, the step S2 is specifically included:
Step S21:Whether the detecting module of safety detecting system judges there is work in washing machine to being scanned in washing machine
Thing.
When detecting module finds being not in washing machine, scan operation is continued executing with, and controller is in and closes shape
State, so as to reduce the energy consumption of washing machine;
When detecting module finds being in washing machine, step S22 is performed.
Step S22:The detecting module of safety detecting system sends signal, wakes up controller, controller control alarm module
Alarm is sent, meanwhile, controller control washing machine forbids all program for washing to start, and door of washing machine is unlocked.
The alarm module of the safety detecting system sends report by the combination of sound, light or sound and light
It is alert.
Step S23:After user receives alarm, washing machine is checked, if there is being (e.g., child in washing machine
Or toy etc.), then it is drawn off in time, alarm module is automatically switched off;
If user is no abnormal after checking washing machine, manual-lock alarm module;
After user's treatment, detecting module proceeds scanning.
In step s3, by washing machine main board power supply, controller is in opening, the step S3 to safety detecting system
Specifically include:
Step S31:Whether the detecting module of safety detecting system judges there is work in washing machine to being scanned in washing machine
Thing.
When detecting module finds being in washing machine, step S32 is performed;
When detecting module finds being not in washing machine, step S34 is performed.
Step S32:The alarm module of safety detecting system sends alarm.
The alarm module of the safety detecting system sends report by the combination of sound, light or sound and light
It is alert, meanwhile, controller control washing machine forbids running all program for washing (will washing machine switch to holding state), and will wash
Clothing gate is unlocked.
Step S33:After user receives alarm, washing machine is checked, if there is being (e.g., child in washing machine
Or toy etc.), then it is drawn off in time, alarm module is automatically switched off, and then performs step S34;
If user is no abnormal after checking washing machine, then manual-lock alarm module performs step
S34;
Step S34:Washing machine starts starts working.
Step S35:Washing machine work is finished, and is shut down.
Then, step S2 is performed.
User is during normally washing machine is used, it is often necessary to stretches into washing machine arm and is operated, and
Detecting module can also be detected when carrying out aforesaid operations being in washing machine, in order to avoid reporting by mistake in this case
It is alert, it is preferable that also to include data analysis in step S21 and step S31, the data that the detecting module is obtained are divided
Analysis, and the arm of normal operating is determined whether according to time duration, imaged shape or movement locus for detecting being etc..
For example, being according to the mode that the time duration for detecting being judges:When the time duration for detecting being is less than
It is judged as normal arm operation during 15s, when the time duration for detecting being is more than 15s, is judged as improper
Arm is operated.When analysis result is the arm of normal operating, then alarm will not be sent, washing machine can be with normal work, otherwise, hair
Go out alarm, forbid washing machine to work.
Further, as shown in Fig. 2 washing machine safety detecting system includes controller 100, detecting module 200 and alarm
Module 300, the detecting module 200 and alarm module 300 are connected with the controller 100.The detecting module 200 is used for
To being detected in washing machine, when the detecting module 200 is detected has being in washing machine, can be to the controller 100
Signal is sent, the controller 100 is received after signal, the alarm module 300 can be controlled to send alarm signal.It is preferred that
Ground, the detecting module 200 is by infrared acquisition detection being.Or, washing machine can also be detected by acoustic detection
Whether the sound frequency of interior object determines whether being in the audio frequency range of being;Microwave sounding, by transmitting
Antenna will produce a microwave warning field for solid in electromagenetic wave radiation to 360 degree of area of space of surrounding, done washing when there is being
When in machine, according to Doppler effect, its back wave can make corresponding oscillation amplitude and frequency change by transmitting antenna, from
And detect the presence of being;Thermal imaging is detected, and determines whether that being is present according to the heat distribution in washing machine.Further
, the detecting module 200 can be detected by the combination of above-mentioned one or more method, or, can also be by other
Mode is detected.

All working, and open the lockable mechanism of door of washing machine.
In a further embodiment, the detecting module 200 of the washing machine safety detecting system includes the He of detector 210
Power supply 220, when washing machine is in running status, the laundry mainboard 1 is powered to the safety detecting system, works as laundry
When machine is in shutdown or holding state, the power supply 220 is used to power the detector 210, and the controller 100 is in
Closed mode, it is ensured that the detector 210 can be detected continuously, and reduce power consumption, when the detector 210 detects laundry
When having being in machine, signal is sent, wake up the controller 100 and detection data is processed.Preferably, the power supply
220 is energy-storage battery, also, in this embodiment, is additionally provided with the controller 100 and the electricity of the power supply 220 is examined
The detection circuit of survey, when the electricity of the power supply 220 is less than predetermined threshold value (such as electricity is less than 20%), to the power supply
220 charge, it is ensured that the power supply 220 has enough electricity, meanwhile, also ensure that the service life of the power supply 220.
The detector 210 can select Infrared Detectors, sound-detection gear, microwave detector or thermal imaging detector
In one or more combination.
In order to avoid the problem that false alarm occurs, analysis program is set in the controller 100, analysis program is by dynamic
Make time, imaged shape or movement locus etc. and judge it is normal operation, still there is being surprisingly to fall into washing machine.
