The present invention is directed at least solve one of technical problem in the prior art.
For this purpose, one aspect of the present invention is designed to provide a kind of door opener.
Another aspect of the present invention is designed to provide a kind of refrigerator for including above-mentioned door opener.
To achieve the above object, the embodiment of one aspect of the present invention provides a kind of door opener, described for refrigerator
Refrigerator includes babinet and the door body that can be rotatablely connected with the babinet, which includes：Box body is arranged on the babinet
On；Knock-pin, the knock-pin are arranged in the box body, and can stretch out the box body for the extended position of enabling and
Retract the box body retracted position between move；Connecting rod, what one end of the connecting rod can be rotated with the knock-pin
Connection；The connection that the other end of pull lever, one end of the pull lever and the connecting rod can rotate；And actuator, it is described
Actuator is connected with the other end of the pull lever, and the actuator drives the pull lever to the direction far from the door body
During movement, the pull lever drives the knock-pin to be moved to the direction close to the extended position by the connecting rod.
The door opener that the above embodiment of the present invention provides, actuator drive pull lever to be moved to the direction far from door body,
The connection that pull lever and connecting rod can rotate, and by connecting rod drive knock-pin to close to the direction of door body (i.e. for opening
The direction of the extended position of door) movement so that knock-pin stretches out box body, reaches extended position, so as to which door body be pushed up from babinet
Go out certain distance, in door body and portion other than connected portion of babinet so that door body and babinet are separated, and user can be manually rotated door body by door again
Body is opened, and realizes the enabling of refrigerator, since under the drive of actuator, one end of knock-pin can stretch out box body, for by door
Open-top certain distance between body and babinet reduces the magnetic force between door body and babinet, and not deposit between door body and babinet
The negative pressure caused by when closed, user pulls the power needed for door body during so as to reduce refrigerator open, and it is special to improve user
The convenience that old man and child open the door, and actuator drive pull lever to the direction far from door body move when, knock-pin to by
The direction of nearly door body is stretched out so that pull lever and the direction of motion of knock-pin increase on the contrary, reduce the volume of door opener occupancy
The strong compactedness of door opener structure；The both ends of connecting rod are rotatably connected respectively with pull lever and knock-pin, improve drawing
The flexibility moved between lever and connecting rod, between connecting rod and knock-pin；It needs at closing time, by either manually or by box
Return unit is set on body so that knock-pin is returned to retracted position, realizes the shutdown of refrigerator.
Door opener is arranged on babinet, it is preferable that door opener is arranged in the outside wall surface of babinet, such as upper surface or
With on the outer side surface of babinet and the junction opposite side of door body, it is preferable that door opener is arranged on the upper surface of babinet,
And set close to the openend of babinet, further, when door body is closed on babinet, the stretching direction of knock-pin is mutually hung down with door body
Directly, to improve open-top effect of the knock-pin to door body, door opener has a certain distance apart from the junction of door body and babinet, makes
It obtains when knock-pin stretches out to having a certain distance at the position of door body and the rotation connection of door body and babinet.
In addition, the door opener that the above embodiment of the present invention provides also has following additional technical feature：
