As shown in fig. 1 and fig. 2, the first embodiment of the present invention discloses a refrigerator, which comprises a box body 10, a box door 20 and a door opening mechanism, wherein the box door 20 is opened by the door opening mechanism, the door opening mechanism comprises a driving rod 30, the driving rod 30 is movably disposed on the box body 10, the driving rod 30 has a first moving direction and a second moving direction, and the driving rod 30 is in driving connection with the box door 20; when the driving lever 30 moves in the first moving direction, the driving lever 30 applies a pushing force to the door 20 and opens the door 20; when the driving lever 30 moves in the second moving direction, the driving lever 30 gradually approaches the rotation axis of the door 20 and pushes the door 20 to expand the opening angle. When the door 20 needs to be opened, the driving rod 30 moves along the first moving direction first, so as to apply an opening thrust to the door 20, and under the action of the thrust applied by the driving rod 30, the door 20 is opened and forms a certain angle with the box body 10, at this time, the driving rod 30 moves along the second moving direction again, and in the moving process along the second moving direction, the driving rod 30 gradually approaches to the rotating shaft of the door 20, and applies the thrust to the door 20 at the same time, so that the opening angle of the door 20 is gradually enlarged, and the door 20 is completely opened.
The utility model discloses an actuating lever 30 of refrigerator not only has first moving direction, still has second moving direction, and actuating lever 30 opens the back with chamber door 20 along first moving direction, can continue to remove along second moving direction to with the opening angle expansion of chamber door 20, guaranteed promptly to utilize less strength to open the door, can also guarantee that the opening angle of chamber door 20 is enough big.
Taking a right-angle acute triangle as an example, when the edge corresponding to the acute angle is translated to the acute angle direction, the acute angle will continuously become large, then infinitely tend to 90 degrees, apply it to the rotation of the box door 20, move to the rotation axis direction of the box door 20 by driving the driving rod 30 with fixed length, the box door 20 which is the acute angle with the box body 10 is pushed by the driving rod 30, thereby realizing the automatic door opening process of the refrigerator.
It should be noted that, in this embodiment, as shown in fig. 2, the first moving direction is an extending direction of the driving rod 30, and the extending direction of the driving rod 30 is perpendicular to the door 20, so that the door 20 can be pushed away from the box 10, and the opening of the door 20 can be realized by overcoming the air pressure inside and outside the refrigerator and the door seal suction force.
The door opening mechanism comprises a driving part 40, and the driving part 40 is arranged on the box body 10; the first end of the driving rod 30 is connected to the driving part 40, and the driving part 40 drives the driving rod 30 to move along the first moving direction and the second moving direction; a second end of drive rod 30 is coupled to door 20 and the second end of drive rod 30 pushes door 20 open. The driving member 40 is configured to drive the driving rod 30 to move in the first moving direction and the second moving direction, so as to open and rotate the door 20 to the maximum opening angle.
It should be noted that, the driving component 40 may be one, that is, it can drive the driving rod 30 to move along the first moving direction, and also can drive the driving rod 30 to move along the second moving direction, for example: the driving rod 30 is movably arranged on the L-shaped guide rail through a sliding block, the turning part of the L-shaped guide rail is arc-shaped, and the sliding block is driven by a motor to move along the guide rail, so that the driving rod 30 is driven to move. In addition, the driving members 40 may be two, one drives the driving rod 30 to move along the first moving direction, and the other drives the driving rod 30 to move along the second moving direction, for example, two air cylinders, or two motors, or a combination of one motor and one air cylinder.
As shown in fig. 2, the door 20 is provided with a guide groove 21, and the second end of the driving lever 30 is movably disposed in the guide groove 21. By movably disposing the second end of the driving rod 30 in the guiding groove 21, the driving rod 30 can be limited by the guiding groove 21, so that the driving rod 30 can move along the guiding groove 21 and simultaneously apply a pushing force to the door 20 through the guiding groove 21.
The guide groove 21 extends from the free end of the door 20 toward the rotation axis of the door 20. When the door 20 is closed, the driving rod 30 is perpendicular to the extending direction of the guide slot 21, and when the driving rod 30 moves along the first moving direction, the second end of the driving rod 30 abuts against the wall of the guide slot 21, so that the pushing force is transmitted to the door 20, and the door 20 is opened. When the door 20 is opened, the driving rod 30 moves in the second moving direction, i.e., along the guide slot 21 toward the rotating shaft, and the second end of the driving rod 30 moves in the guide slot 21 while applying a pushing force to the side wall of the guide slot 21, so that the door 20 rotates and is opened to the maximum position.
It should be noted that the guide slot 21 is located at the top of the box door 20, and the driving rod 30 is located at the top of the box body 10. The uniform opening of the door body is realized by calculating the motion process of the driving rod 30.
Since the driving lever 30 is a straight lever, when the door 20 approaches the maximum angle, the driving lever 30 restricts the opening angle of the door 20, so that the door 20 cannot be opened to the maximum angle.
In order to solve this problem, as shown in fig. 3 and 4, the driving rod 30 includes a telescopic rod 31 and a rotating rod 32, the telescopic rod 31 is drivingly connected to the driving member 40, one end of the rotating rod 32 is connected to the telescopic rod 31, the other end of the rotating rod 32 is movably disposed in the guide groove 21, and the rotating rod 32 is capable of rotating in one direction. In the process that the telescopic rod 31 moves along the second moving direction, the rotating rod 32 is driven by the telescopic rod 31 to push the box door 20 to expand the opening angle; at the maximum stroke position of the telescopic rod 31 moving along the second moving direction, the box door 20 continues to rotate to the maximum opening angle under the inertia effect, and the rotating rod 32 is driven by the box door 20 to rotate. As shown in fig. 3, by providing the rotation rod 32 and enabling the rotation rod 32 to rotate in one direction, the rotation rod 32 may push the door 20 to rotate when the retractable rod 31 moves along the second moving direction, or may avoid limiting the opening angle of the door 20 along with the rotation of the door 20 when the door 20 rotates to the maximum opening angle, so as to maximize the opening angle of the door 20.
As shown in fig. 5, the first limiting portion 33 is disposed on the telescopic rod 31, and as shown in fig. 5, the first limiting portion 33 is disposed at a connecting position of the telescopic rod 31 and the rotating rod 32, and the telescopic rod 31 drives the rotating rod 32 to move along the second moving direction, and at the same time, the first limiting portion 33 limits the rotating rod 32 to rotate, so that the rotating rod 32 continuously pushes the door 20.
It should be noted that, the telescopic rod 31 is further provided with a second limiting portion 34, as shown in fig. 5, the second limiting portion 34 is disposed at a connecting position of the telescopic rod 31 and the rotating rod 32, and is opposite to the first limiting portion 33, and the second limiting portion 34 is used for limiting a rotation angle of the rotating rod 32 in the other direction, so as to prevent the door 20 from being closed due to an excessively large rotation angle of the rotating rod 32 in the other direction.
It should be noted that, when the driving rod 30 moves to the maximum stroke position, the outer end point is outside the rotating shaft of the door 20, and the force arm is larger than the rotating shaft, so that the driving rod 30 drives the door 20 to rotate reversely when returning, and the door body is closed.
The door closing process of the refrigerator is that the driving rod 30 makes uniform acceleration motion towards the initial position direction, at the moment, the front driving rod 30 starts to rotate in the opposite direction under the action of force until being limited by the second limiting part 34, the door 20 is pulled by the driving rod 30, the door 20 starts to be closed, when the driving rod 30 moves to the initial position of the second moving direction, the door 20 and the box body 10 form an acute angle, the driving rod 30 stops moving transversely, the driving rod 30 moves along the opposite direction of the first moving direction, and the door closing process is completed.
The door opening mechanism includes a reset sleeve in which the drive lever 30 is disposed, the reset sleeve being configured to guide the rotating lever 32 to be reset when the drive lever 30 moves in a direction opposite to the first moving direction. When the driving rod 30 moves in the direction opposite to the first moving direction, the driving rod 30 is reset to the angle capable of guiding the rotating rod 32, so that the telescopic rod 31 and the rotating rod 32 form a straight line, namely 180 degrees, when the driving rod 30 moves in the first moving direction to push the box door 20 away, the reset sleeve can limit the rotating rod 32, and the rotating rod 32 is prevented from rotating and deviating.
It is to be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. It is not exhaustive here for all embodiments.
