In addition, those skilled in the art can also be as needed, solve door lock 2 automatically after laundry washer terminates
Lock, and then upper cover 3 is enable to be automatically switched on.
In addition, the automatic lid closing/opening method specifically includes that step the present invention also provides the automatic lid closing/opening method of above-mentioned washing machine
Rapid S10 judges the current operating conditions of washing machine and the current switch states of upper cover 3；Step S20, when washing machine is in laundry
Machine terminates state and when upper cover 3 is in close state, and is powered for the first time to door lock 2 and therefore locking door lock 2；Step S30, in door
It locks 2 to be powered for the first time in the set period of time after locking, be powered for the second time to door lock 2 and therefore makes the unlock of door lock 2；Step
S40, after the unlock of door lock 2, upper cover 3 is automatically opened.
Specifically, in step slo, the current operating conditions and upper cover 3 of washing machine are detected by relevant sensor
Current switch states judge that washing machine is to terminate state or shutdown shape in booting not running state, laundry state, washing machine
State.Judge that upper cover 3 is opening state or closed state.It will be appreciated to those of skill in the art that the sensor can be
Any sensor for being able to detect 3 current state of upper cover, for example, be arranged on upper cover 3 or cabinet 4 close to switch, be arranged upper
Angular transducer, the photosensitive sensor being arranged on cabinet 4 on the pivotal axis of lid 3 etc..
Specifically, in step S20, when step S10 detection result be washing machine be in washing machine terminate state and on
Lid 3 locks the driver energization 0.02S of door lock 2 by the gate stop 1 of occlusion and lock 22 in when being closed state, from
And upper cover 3 is locked to closed state.
Specifically, in step s 30, when driver is once again powered up 0.02S in the set period of time after step S20,
Driving lock 22 is moved to unlocked position, and gate stop 1 and lock 22 is made to be detached from occlusion.The set period of time is preferably 1S, or
Those skilled in the art can also as needed be adjusted correspondingly set period of time, for example, setting the set period of time to
2S, 0.5S, 0.1S etc..In addition, those skilled in the art can also be as needed, by the conduction time of the driver of door lock 2 into
Row appropriate adjustment, such as 0.02S is adjusted to 0.05S, 0.1S, 0.01S etc..
Specifically, in step s 40, door closure 3 passes through second back-moving spring after gate stop 1 and lock 22 are detached from occlusion
Effect can automatically open.
For step S20, corresponding there are two types of embodiments.The first embodiment is washed after laundry washer terminates
The controller of clothing machine, which controls corresponding electric switch, makes the driver of door lock 2 be powered.Second of embodiment, user presses/touches/
The driver of key back door lock 2 of uncapping on washing machine is powered.In the second embodiment, it is preferable that uncap key by with
The controller of washing machine is signaled to after the operation of family, controller, which controls corresponding electric switch, makes the driver of door lock 2 be powered.Or
Person can also make whether obtaining electric of key direct controlling and driving device of uncapping.
In step s 30, accordingly with the first embodiment in step S20, the 1S after the energization of driver first
At the time of, controller is being once again powered up driver, and lock 22 is made to be moved to unlocked position.With second of implementation in step S20
Accordingly, at the time of the 1S after the energization of driver first, controller is being once again powered up driver to mode, moves lock 22
It moves to unlocked position.
It should be noted that washing machine is powered once in the front door lock 2 for starting program for washing, upper cover 3 is locked in closing
State prevents upper cover 3 to be accidentally opened in the washing machine course of work.
It should also be noted that, driver does not work after washing machine shutdown, latched under the action of first back-moving spring
22 are at position shown in Fig. 3, to keep upper cover 3 in off position.User can firmly pull in upper cover 3 at this time
Handle is detached from gate stop 1 and is engaged with lock 22, and then opening upper cover.
In conclusion washing machine of the invention can automatically open upper cover after washing machine terminates, liberate user's
Both hands optimize the usage experience of user.
So far, it has been combined preferred embodiment shown in the drawings and describes technical solution of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific embodiments.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to the relevant technologies feature, these
Technical solution after change or replacement will fall within the scope of protection of the present invention.
