First on 10 magnetic devices 51 and the second magnetic devices 52 for being set in door body 20, and are being arranged using refrigerator 100
When touch device 60 detects the trigger action for opening door body 20, the first magnetic devices 51 and the generation of the second magnetic devices 52 repel each other
The second magnetic force, with assist user open door body 20, in addition, touch device 60 according to the detection result of body-sensing detector 40 carry out
Triggering, on the one hand can prevent 60 error detection of touch device from interfering, and it is long-term on the other hand can also to save touch device 60
The electric energy of consumption in operation effectively promotes the usage experience of user.
Fig. 6 is the schematic diagram of the open and close control method of refrigerator door in accordance with another embodiment of the present invention.As shown,
The open and close control method of the refrigerator door includes:
Step S602 detects the closed state of door body 20；
Step S604,20 opening time of door body are more than the first preset duration, if so, executing step S606, are held if it is not, returning
Row step S602；
Step S606 drives the first magnetic devices 51 and the second magnetic devices 52 to generate attracting third magnetic force, so that door
Body 20 is closed；
Step S608 detects the closed state of door body 20 again；
Step S610,20 opening time of door body are more than the second preset duration, if so, executing step S612, are held if it is not, returning
Row step S608；
Step S612, control alarm device 70 export warning information, to remind user to close door body 20.
After comparing the shutdown signal for obtaining door body 20 and determining that user leaves the region of refrigerator front preset distance, the first magnetic
Property device 51 and the second magnetic devices 52 generate the first attracting magnetic force, and the third magnetic force in step S606 wants stronger, first
In the case that magnetic force can not be such that door body 20 completely closes, use stronger third magnetic force that door body 20 is closed, it can be to avoid door
The leakage of cooling capacity caused by body 20 is opened for a long time influences the problems such as storing effect.Wherein it is possible to be powered by changing to electromagnet
The size of electric current adjusts the power of magnetic force.Such as to electromagnet electrical current be I1 when, the first magnetic devices 51 and the second magnetic
Property device 52 generates the first attracting magnetic force；When to electromagnet electrical current being I3, the first magnetic devices 51 and the second magnetic dress
The attracting third magnetic force of 52 generations is set, wherein I1 is identical as the direction I3, and I3 > I1, then third magnetic force is better than the first magnetic force.
20 opening time of door body in step S610 is since the closed state for detecting door body 20 again of step S608
Reclocking, and the second preset duration can be less than the first preset duration.Such as first preset duration be 10 minutes, second is pre-
If when it is 5 minutes a length of, in door body 20 when being not turned off within 10 minutes, the first magnetic devices 51 and the second magnetic devices 52 is driven to produce
Raw attracting third magnetic force, so that door body 20 is closed, if door body 20 is still not turned off, and 20 opening time of reclocking door body reaches
By 5 minutes, then illustrating that door body 20 is likely to break down, can not close, the specific value of the second preset duration can be slightly smaller, with
Just it reminds user's door body 20 to be not turned off in time, in order to avoid cooling capacity leakage is excessive, seriously affects the storing effect of refrigerator compartment.
Alarm device 70 in step S612 can be buzzer, and warning information accordingly can be buzzing alarming sound, this
Other type of alarms, such as luminous alarm etc. can also be used outside.
The open and close control method of the refrigerator door of the present embodiment can detecte the closed state of door body 20, and in door body 20
When opening time is more than the first preset duration, the first magnetic devices 51 and the second magnetic devices 52 is driven to generate attracting third magnetic
Power, so that door body 20 is closed；The first magnetic devices 51 and the second magnetic devices 52 are being driven to generate the step of attracting third magnetic force
The closed state of door body 20 is detected after rapid again, and when 20 opening time of door body being more than the second preset duration, controls alarm
Device 70 exports warning information, to remind user to close door body 20, can not close in door body 20 because of failure or other reasons
When, it reminds user to check in time, in order to avoid cooling capacity leakage is excessive, seriously affects the storing effect of refrigerator compartment.
So far, although those skilled in the art will appreciate that present invention has been shown and described in detail herein multiple shows
Example property embodiment still without departing from the spirit and scope of the present invention, still can according to the present disclosure directly
Determine or deduce out many other variations or modifications consistent with the principles of the invention.Therefore, the scope of the present invention is understood that and recognizes
It is set to and covers all such other variations or modifications.
