Refrigerator and refrigerator door

Technical field

The invention relates to a refrigerator and a refrigerator door thereof, in particular to a refrigerator having a micro door which can be opened separately and a refrigerator door thereof, belonging to the field of household appliances.

Background technique

Existing refrigerators with bar counters generally use a fixed push-bar bar lock to open and close the bar door. However, this fixed push-type bar lock cannot adjust the gap between the bar door and the door of the refrigerator, so that when the gap between the bar door and the door of the refrigerator is too small, it is difficult to open the bar door. In the case where the gap between the bar door and the door of the refrigerator is too large, the sealing may be poor, and not only the leakage may occur, but also the power consumption may become large.

In addition, the existing fixed push-type bar lock, in use, needs to push the bar door inward a certain distance, so that the bar lock automatically bounces, thereby realizing the automatic opening of the bar door. However, due to the flexibility of the bar lock, it is often the case that the appearance of the bar door and the appearance of the door of the refrigerator are not on one plane, thereby affecting the appearance of the entire refrigerator.
