Door body assembly for built-in refrigeration device, and refrigeration device

A door body assembly for an embedded refrigeration apparatus, comprising:

• a box door rotatably connected to a refrigeration box body, wherein the refrigeration box body is embedded in an accommodation space formed by a mount body, a distance between a hinge shaft center of the box door and an opening of the accommodation space is t, and a distance between the hinge shaft center and an end surface of the box door on a hinge side is l3;
• a slide mechanism;
• a door panel movably mounted to the box door through the slide mechanism, movable along a width direction of the box door by a movement distance, d the door panel having an interference position, wherein the interference position is an outer corner of the door panel on a hinge side;
• and
• a traction mechanism connected to the slide mechanism, wherein during an opening and closing process of the box door, the traction mechanism drives the slide mechanism to cause the door panel to move relative to the box door;
• wherein a maximum door opening angle of the door body assembly is 90° to 135°, a minimum value of the movement distance d of the door panel is between 14.15 mm and 109.108 mm, and the maximum door opening angle is positively correlated with the minimum value of the movement distance d.
