[0039] In order to further clarify the technical means and effects taken by the utility model to achieve the predetermined utility model purposes and effects, the following will be combined with the drawings and the preferred embodiments to specifically describe the specific embodiments, structures, features and effects according to the utility model application. In the following description, different "an embodiment" or "embodiments" do not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.

[0040] In the description of the utility model, it is necessary to make clear that the terms "first", "second" and the like in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence; The terms "vertical", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "horizontal" and the like indicate the orientation or positional relationship shown in the drawings, and are only used for the convenience of describing the utility model, and do not mean that the device or element referred to must have a specific orientation or position, so it cannot be understood as a limitation on the utility model.

[0041] In the description of the utility model, it is necessary to make clear that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; It can be mechanically connected, or it can be electrically connected; It can be directly connected, or it can be indirectly connected through an intermediate medium. For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0042] In order to ensure that the left and right door bodies can be normally opened and closed, a closed space is formed when the door bodies are closed, and in order to ensure that the left and right door bodies do not leak cold, a turnover beam is needed to form a mechanical turnover structure for the left door body, the turnover beam is perpendicular to the door surface when the door body is opened, and the turnover beam is guided by a turnover beam guide block on the top of the foamed box body during the closing process of the door body, at this time, the left and right door bodies and the turnover beam form a closed space. In order to prevent condensation caused by door body leakage, heating wires are pre-buried in the turnover beam, and the structure of the pre-buried wire box determines the production mode of the door body and the turnover mode of the turnover beam of the door body, thereby affecting the sealing and heat preservation effect of the refrigerator.

[0043] The original door body structure is shown in Figures 8-9 The door body structure is composed of a door shell assembly 1, a door tank assembly 2, a wire box 5 and a first wire harness 6 and a second wire harness 7. The door shell assembly 1 is installed on the lower mold of the foaming mold, and the door tank assembly 2 and the wire box 5 are assembled and installed on the upper mold of the foaming mold. The terminal at one end of the first wire harness 6 is pre-installed in the wire box 5 on the door tank assembly 2, and the other end is connected to the heating wire wiring in the turnover beam during the assembly of the refrigerator. The terminal at one end of the second wire harness 7 passes through the center hole of the rotating shaft 13 of the upper end cover 12 of the door shell assembly 1, and is connected to the refrigerator box wiring in the assembly process. The terminal at the other end is placed in the door shell and is ready to use. The connection of the first wire harness 6 and the second wire harness 7 needs to stop the foaming assembly line, and the two terminals of the first wire harness 6 and the second wire harness 7 are connected manually. This process needs to stop the assembly line, resulting in low efficiency.

[0044] In addition, the included angle of the upper and lower molds after opening is obtuse, in order to ensure normal connection, the total length of the first wire harness 6 and the second wire harness 7 needs to be 2m, and the actual length of the wire box 5 after the mold is closed is only 1m, which causes material waste. During the terminal insertion process, a person needs to stand on the equipment to operate, which is dangerous. Due to the excessive length of the wire harness, the wire harness is pressed outside the door body during the mold closing process, which causes quality problems such as door body scrap.
