Embodiment Construction
[0035] figure 1 is a schematic sectional view of an inner door body according to an embodiment of the present invention. Such as figure 1 As shown, the embodiment of the present invention provides an inner door body 100 for a double-layer door body assembly in a freezer and refrigerator, which generally includes a door frame 10 . figure 2 It is a schematic structural diagram of an inner door frame according to an embodiment of the present invention. Such as figure 2 As shown, the door frame 10 has a door opening 11 for taking and placing items from the front side of the inner door body 100 and an inner wall 12 defining the door opening 11 . That is to say, the inner wall 12 is arranged around the door opening 11 . When one or more storage boxes are installed on the side of the door frame 10 toward the interior of the refrigerator-freezer, the user can take and place the items in one or more storage boxes through the door opening 11; When one side of the storage box is n...

The invention relates to an inner door body and a freeze and refrigeration device provided with the same. Specifically, the invention provides the inner door body which comprises a door frame and a reinforcing structure. The door frame is provided with a door hole and an inner wall used for limiting the door hole, wherein the door hole allows a person to take out and place objects from the front side of the inner door body. The reinforcing structure is fixedly arranged on the inner wall and used for supporting the inner wall. In addition, the invention further provides the freeze and refrigeration device provided with the inner door body. According to the inner door body and the freeze and refrigeration device provided with the inner door body, the reinforcing structure is arranged on the inner wall, surrounding the door hole, of the door frame; and the reinforcing structure can support the inner wall of the door frame, and bears foaming pressure generated by foaming materials in the foaming process on the inner wall of the door frame, so that the inner wall of the door frame is prevented from protruding and deforming towards the door hole. Meanwhile, the reinforcing structure can also bear adhesive power generated by shrinkage of the foaming materials in the cooling process of the foaming materials and in the use process of the freeze and refrigeration device on the inner wall of the door frame, so that the inner wall of the door frame is prevented from deforming concavely towards the door hole.
Description
technical field [0001] The invention relates to a door body, in particular to an inner door body used for a double-layer door assembly in a freezer and freezer and the freezer and freezer. Background technique [0002] A door-in-door refrigerator (or double-door refrigerator) generally includes a box body, an inner door and an outer door pivotally connected to the box body. The inner door is usually a frame body hollowed out in the middle to form a door opening in the frame body, so that users can directly access the items inside the refrigerator through the door opening. The door frame and door lining of the inner door are both hollow, and the two cooperate to form the frame of the inner door. The gap between the door frame and the door lining is punched with foam material to achieve the effect of sealing and heat preservation. [0003] However, as the refrigerator becomes larger and larger, the opening area of the inner door is also larger, and the frame support of the ...
