Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1, a refrigerator with improved sealing performance includes an outer case 1 and a door 2. The inside cold-stored chamber that is equipped with of shell 1, its lateral part is equipped with the intercommunication the opening in cold-stored chamber. The bottom of the shell 1 is provided with universal wheels 8 which are convenient for transferring the shell. One side of the door body 2 is rotatably arranged on the side wall of the shell 1 and is used for opening or closing the opening, and the other side of the door body horizontally extends for a preset distance to form a manual push-pull part. And a sealing piece which is arranged on the side wall of the shell 1 and corresponds to the periphery of the opening and ensures the sealing property of the refrigerating cavity after the opening is closed by the door body 2. The top of the door body 2 is provided with a pulling mechanism, and the pulling mechanism pulls the door body 2 towards the cold storage cavity to extrude the sealing piece to improve the sealing performance of the cold storage cavity when the opening is closed. The pulling mechanisms are provided with a plurality of pulling mechanisms which are uniformly arranged at the top of the door body 2.

As shown in fig. 2, an arc-shaped chute 3 is disposed on the inner sidewall of the top of the opening and above the pulling mechanism. The starting end of the sliding groove 3 is flush with the opening, and the terminating end extends towards the refrigerating cavity for a preset distance. As shown in fig. 3 and 4, the pulling mechanism includes a rotating shaft 4 and a ball 5. The top of the door body 2 is provided with a mounting groove 6 at a position corresponding to the sliding groove 3, and the ball rotating shaft 4 is horizontally fixed inside the mounting groove 6. The ball body 5 is installed on the rotating shaft 4 in a circumferential rotating manner and can horizontally slide, the lower portion of the ball body 5 is located in the installation groove 6, the upper portion of the ball body 5 exceeds the upper end of the door body 2 and corresponds to the starting end of the sliding groove 3 so as to enter the sliding groove 3 when the opening is closed, and then the door body 2 is pulled towards the refrigerating chamber through the ball body 5 under the action of the sliding groove 3 and extrudes the sealing piece.

And the rotating shaft 4 is provided with a limiting mechanism which ensures that the position of the ball body 5 before the opening is closed is aligned with the starting end of the sliding groove 3. The limiting mechanism is composed of two springs 7, the two springs 7 are respectively sleeved on the rotating shaft 4 and correspond to the positions on the two sides of the ball body 5, and the two ends of each spring 7 respectively abut against the inner wall of the mounting groove 6 and the corresponding position of the ball body 5 so as to ensure that the position of the ball body 5 before the opening is closed is aligned with the starting end of the sliding groove 3.

Before the door body 2 closes the opening, the sphere 5 is in the preset position under the action of the two springs 7, namely the position of the sphere 5 at the moment is aligned with the starting end of the chute 3, so that the upper part of the sphere 5 can smoothly enter the chute 3 through the starting end of the chute 3 in the process of rotating the door body 2 to close the opening. After that, along with the in-process that the continuous rotation door body 2 closed the opening gradually, spheroid 5 can be earlier in the inside motion of cold-stored chamber under the direction of spout 3 and preset the distance back towards one side motion of cold-stored chamber again, and the above-mentioned motion trail of spheroid 5 can drive door body 2 towards cold-stored chamber extrusion sealing member, and then ensures that the clearance between door body 2 and the opening can be sealed by the sealing member, very big improvement the sealing performance in cold-stored chamber.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
