Embodiments of the present disclosure relate to the field of refrigeration, and more particularly to a refrigerator and a door locking assembly for the refrigerator.
The existing refrigerators such as French side by side type refrigerator and Japanese multiple-door type refrigerator have a large refrigeration compartment which is convenient for use. In the refrigerator having two doors disposed side by side, a movable rotating beam needs to be provided between the two doors in order to seal the refrigeration compartment. Due to the poor stopping effect, the door on one side may be opened because of the air pressure during closing the door on the other side, thus causing refrigeration leakage of the refrigerator.
Embodiments of the present disclosure seek to solve at least one of the problems existing in the related art to at least some extent.
Accordingly, an object of the present disclosure is to provide a door locking assembly for a refrigerator. The door locking assembly may lock a door of the refrigerator onto the refrigerator body of the refrigerator.

A door locking assembly for a refrigerator according to embodiments of the present disclosure will be described below with reference to the drawings.
As shown in
Specifically, the stopping member 10 is disposed on the door 80. Alternatively, the stopping member 10 may be fixed on the door 80.
The pivoting shaft 20 is mounted on the door 80 along a vertical direction, for example, the vertical direction is perpendicular to the paper sheet in
The rotating member 30 defines a first end 31 pivotably connected with the pivoting shaft 20 so as to rotate about the pivoting shaft 20 in the horizontal plane, for example, the plane defined by the paper sheet, and a second end 32. The stopping member 10 is configured to stop the rotating member 30 at a predetermined position.
The elastic member 40 defines a first end 41 fixed on the door 80 and a second end 42 connected with the rotating member 30, so as to apply a force on the rotating member 30 and to abut the rotating member 30 against the stopping member 10.
The positioning member 50 is disposed on the cabinet 90 and configured to engage with the second end 32 of the rotating member 30 so as to lock the door 80 onto the cabinet 90 when the door 80 is closed.
With the door locking assembly for a refrigerator according to embodiments of the present disclosure, when the door 80 is in a closed state, the door 80 may be locked tightly with the positioning member 50 via the rotating member 30, thus locking the door 80 onto the cabinet 90. In this way, even when the air pressure in a refrigeration compartment of the cabinet 90 is increased suddenly, the door 80 may not be opened. The door 80 is locked tightly on the cabinet 90, which ensures that the refrigeration leakage of the refrigerator is prevented efficiently.
As shown in
In other words, the rotating member 30 and the positioning member 50 are engaged with each other via the first hook 321 formed at the rotating member 30 and the second hook 501 formed at the positioning member 50. Thereby, when the door 80 is closed, the first and second hooks 321, 501 are engaged to lock the rotating member 30 and the positioning member 50, thus locking the door 80 onto the cabinet 90 via the rotating member 30 and the positioning member 50.
As shown in
Alternatively, the elastic member 40 and the stopping member 10 are positioned on opposite sides of the rotating member 30 respectively, and the elastic member 40 is configured to apply a compression force on the rotating member 30. Thereby, the rotating member 30 may be driven by the compression force of the elastic member 40 such as a spring and abuts against the stopping member 10, thus positioning at a predetermined position with regard to the door 80. For example, the predetermined position is advantageous for locking the rotating member 30 and the positioning member 50.
As shown in
In some embodiments, the hinge 70 is a top-mounted hinge, and a groove 60 is formed in an upper end of the door 80 and adapted to receive the stopping member 10, the pivoting shaft 20, the rotating member 30 and the elastic member 40. The groove 60 and the top-mounted hinge are corresponding to each other in position, thus facilitating to engage the rotating member 30 with the positioning member 50. The door locking assembly according to embodiments of the present disclosure may be arranged externally of the refrigeration compartment of the refrigerator, thus the reliability of the door locking assembly during use may be improved.
As shown in
In some embodiments, a snapping groove (not shown) is formed in the positioning member 50, and the second end 32 of the rotating member 30 has a protrusion (not shown) adapted to be elastically engaged into the snapping groove. When the door 80 is in the closed state, the protrusion is inserted in the snapping groove in order to lock the door 80 on the cabinet 90.
The operation process of the door locking assembly for a refrigerator according embodiments of the present disclosure will be described below with reference to the drawings.
When the door 80 changes from an open state to a closed state, the rotating member 30 is perpendicular to the door 80. During the rotating process of the door 80, the first hook 321 of the rotating member 30 is contacted with the second hook 501 of the positioning member 50. As the door 80 keeps on rotating, the rotating member 30 is rotated about the pivoting shaft 20 due to the interaction between the first and second hooks 321, 501. Then the elastic member 40, such as a spring, is stretched (as shown in
When the door 80 changes from the closed state to the open state, the operation process of the door locking assembly for a refrigerator according to embodiments of the present disclosure is in contrary to the operation process described above (i.e. the operation process during the door 80 changing from the open state to the closed state), thus details thereof are omitted herein.
As shown in
Specifically, the cabinet 90 defines a refrigeration compartment (now shown) therein.
The door 80 is pivotably connected with the cabinet 90 via a hinge 70 and configured to open and close the refrigeration compartment.
The door locking assembly is the above-identified door locking assembly according to embodiments of the present disclosure, and configured to lock the door 80 onto the cabinet 90.
The refrigerator according to embodiments of the present disclosure has the door locking assembly. When the door 80 is in a closed state, the door 80 may be locked tightly on the positioning member 50 via the rotating member 30, thus locking the door 80 onto the cabinet 90. In this way, even when the air pressure in the refrigeration compartment is increased suddenly, the door 80 may not be opened. The door 80 is locked tightly on the cabinet 90, which ensures that the refrigeration leakage of the refrigerator is prevented efficiently.
In some embodiments, the refrigerator is configured as a side by side type refrigerator. The side by side type refrigerator may include two doors arranged side by side, and the refrigerator includes two door locking assemblies adapted to lock the two doors onto the cabinet respectively. Thereby, when the air pressure in the refrigeration compartment is increased suddenly, for example, during a process that one door changes from the open state to the closed state while the other door is in the closed state, the other door being opened due to the increased air pressure may be efficiently prevented by using the refrigerator according to embodiments of the present disclosure.
