The sealing bladder 130 extends less than the first cavity 111 to ensure that the sealing bladder 130 can enter the first cavity 111. In this embodiment, the sealed bladder 130 may be made of an elastomeric material such as PVC.

The inflator 140 is in direct or indirect communication with the sealed bladder 130 and is configured to inflate or deflate the sealed bladder 130. In the present embodiment, the inflator 140 is a micro inflator.

One end of each telescopic component is fixedly connected with the inner wall of the first cavity 111, the other end of each telescopic component extends out towards the second door body 120 and is connected with the sealing airbag 130, and the telescopic components are configured to be controllably telescopic so as to drive the sealing airbag 130 to move towards the second door body 120 to a first preset position abutting against the end face of the second door body 120, or move away from the second door body 120 to a second preset position hidden in the first cavity 111.

In the present embodiment, the telescopic member is a telescopic airbag 150, and the inflator 140 is in communication with the telescopic airbag 150 and inflates or deflates the telescopic airbag 150 to control the telescopic airbag 150 to expand or contract. The airbag 150 is a strip-shaped airbag extending in the transverse direction of the door body, and the airbag wall of the airbag 150 has a folded structure. When the bellows airbag 150 is inflated, the bellows structure is deployed and the bellows airbag 150 is extended; when the bellows 150 is deflated, the bellows structure compresses and the bellows 150 shortens. Preferably, the number of the bellows 150 is two, and the bellows is respectively disposed at positions close to the top and the bottom of the first door body 110. In other embodiments of the present invention, 3 or more than 3 telescopic bladders 150 may be provided in order to ensure smooth movement of the sealing bladder 130. Preferably, the plurality of airbags 150 are arranged at equal intervals along the vertical direction of the first door body 110.

The sealing airbag 130 is further covered with an airbag housing 180 for protecting and supporting the sealing airbag 130 to prevent the sealing airbag 130 from being deformed when it is contracted.

The split door body assembly 100 further includes: and (4) a detection device. The detection device is disposed on the first door 110 or the second door 120, and is configured to detect an open/close state of the split door. The inflator 140 is further configured to inflate the airbag 130 when the detection device detects that the door body is closed; when the detection device detects that the door body is opened, the sealing air bag 130 is deflated. In this embodiment, the detection device may specifically be a hall switch or a mechanical switch disposed at an edge of the door body, and the open/close state of the side-by-side door is determined by detecting the on-state.

The specific working principle of the split door body assembly 100 of the present embodiment is as follows: when the side-by-side door is in the open state, both the air bag 130 and the air bag 150 are in the uninflated state. When the user closes the side-by-side door, the detection means detects that the side-by-side door is closed, the inflator 140 is activated, and inflates the inflation channel 170 with gas. The airbag 150 is first inflated and gradually extended, and the airbag 150 horizontally pushes the airbag 130 from the second predetermined position to the first predetermined position. In this process, gas cannot enter the air bag 130 from the air bag 150 due to the valve switch 160, and therefore, the air bag 130 is still in the contracted state when it has just moved to the first preset position. When the inflator 140 further inflates the airbag 150 and the air pressure in the airbag 150 exceeds the preset air pressure value, the valve switch 160 is automatically opened, and the inflator 140 further inflates the airbag 130. The inflator 140 inflates the sealing airbag 130 for a preset time and then stops, at this time, the sealing airbag 130 fully expands and completely seals the gap between the first door body 110 and the second door body 120, and a part of the sealing airbag 130 in the expanded state is embedded into the second cavity 121, so as to ensure the sealing property of the gap between the door bodies. When the detection device detects that the side-by-side door is opened (or detects that the side-by-side door has an opening trend), the inflating device 140 starts to perform deflation operation on the sealing airbag 130 and the telescopic airbag 150, the sealing airbag 130 and the telescopic airbag 150 contract, the telescopic airbag 150 drives the sealing airbag 130 to retract to a second preset position, at the moment, the sealing airbag 130 is hidden in the first cavity 111, a user cannot observe the sealing airbag 130, and the sealing airbag 130 cannot influence the operation of the user.

In other embodiments of the present invention, the telescopic member may be a push rod driven mechanically. When the detection device detects that the side-by-side door is closed, the stepping motor starts the driving push rod to drive the sealing air bag 130 to move to the first preset position. A pressure sensor is provided inside the second cavity 121 to detect whether the sealing bladder 130 contacts the second door body 120. When the pressure sensor detects that the air bag 130 contacts the second door 120, the step motor stops operating, and the inflator 140 is restarted to directly inflate the air bag 130. When the detection device detects that the side-by-side door is opened, the inflator 140 is first activated to deflate the airbag 130. The stepping motor is restarted to drive the push rod to drive the sealing air bag 130 to move to a second preset position, and at the moment, the sealing air bag 130 is completely retracted into the first concave cavity 111.

The present invention also provides a refrigerator including: a case 200 and the split door body assembly 100. The cabinet 200 forms a storage compartment of the refrigerator therein. The split door assembly 100 is disposed at a front side of the cabinet 200 to open and close the storage compartment. According to the side-by-side combination refrigerator, the sealing air bag 130 in the side-by-side combination door body assembly 100 replaces a vertical beam structure in the prior art, the sealing performance of the side-by-side combination door is improved, and cold leakage of a storage chamber of the refrigerator is effectively prevented. In addition, when the side by side combination door is opened, the sealing air bag 130 and other auxiliary structures can be hidden inside the first cavity 111, so that the appearance of the refrigerator is more symmetrical and beautiful.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
