A pre-embedded box structure, a door body for a refrigerator and a refrigerator

Abstract

The invention relates to the technical field of refrigeration equipment, in particular to a pre-buried box structure, a door body used for a refrigerator and the refrigerator. The pre-buried box structure comprises a pre-buried box body. One surface of the pre-buried box body is provided with a primary foaming area, and the other surface of the pre-buried box body is provided with a display screen installation area and a secondary foaming area, the display screen installation area is used for containing a display screen, and the display screen installation area and the secondary foaming area are separated through protruding edges protruding out of the surface of the pre-buried box body. The pre-buried box structure, the door body used for the refrigerator and the refrigerator have the beneficial effects that during primary foaming, the space in front of the display screen installation area is open, and thus a tool can be placed in the display screen installation area so that the purpose of preventing the pre-buried box body from being foamed and deformed can be achieved; after primary foaming is conducted, the pre-buried box body is shaped, so secondary foaming cannot deform the pre-buried box body; and secondary foaming is conducted in the secondary foaming area, and much adhesive force can be applied to door glass through foam liquid, so that falling off of the glass is prevented.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a pre-embedded box structure, a door body for a refrigerator and the refrigerator. Background technique [0002] With the rapid development of high-end refrigerators, refrigerators with super-large display screens have become a trend, and major manufacturers have increased R&D investment to develop refrigerators with large LCD display screens. [0003] The small display screen of a traditional refrigerator is small in size, and the display screen can be installed only by designing a small pre-embedded box in the door body. When the door body is foamed, the pre-embedded box is not easily deformed because of its small size. But for super-large LCD display screens, due to the large display area (up to 21.5 inches or larger), this requires that the embedded box used to install the display screen should be increased accordingly, but such a large embedded box in the do...

Problems solved by technology

But for super-large LCD display screens, due to the large display area (up to 21.5 inches or larger), this requires that the embedded box used to install the display screen should be increased accordingly, but such a large embedded box in the door body When foaming, it will inevitably be deformed by the extrusion of the foam liquid, which will affect the installation of the display screen

For steel doors, since the space in front of the pre-embedded box is open, large pieces of tooling can be used inside the pre-embedded box to prevent deformation. Large pieces of tooling are used in the box to prevent deformation, so there is currently no effective way to solve the problem of foaming and deformation of the large pre-embedded box in the glass door

[0004] At the same time, the traditional refrigerator door pre-embedded box has a small display screen and emits less heat, so there is no need to consider heat exchange with the outside world. However, the super-large LCD screen has a large power and emits a lot of heat. If the heat cannot be released in time, the pre-installed The temperature in the buried box is too high, causing the display to crash
