[0002] Refrigerators have become an indispensable household appliance in people's daily lives. As people's living standards are getting better and better, more families use large-capacity refrigerators, and the refrigerator compartments are all double-door structures. The flip beam is generally installed on the left door of the refrigerator compartment. When the door body is opened and closed, the flip beam rotates from the stowed position to the unfolded position to seal the gap between the two doors to prevent cold air leakage.
[0003] Under normal circumstances, there is an anti-condensation heater on the back of the door beam of the flip beam to ensure that there is no condensation on the front during normal use. However, during use, because there is no heater on the top and bottom, there is a risk of condensation on the upper and lower parts of the flip beam during normal operation of the refrigerator in rainy seasons with high humidity. Water droplets can be seen when opening the door, which has caused complaints from customers. Utility Model Content

DETAILED DESCRIPTION
[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] See also Figure 1-8 As shown, the utility model is a turning beam of a refrigerator, comprising an intermediate frame 1, a first cover body 2, a second cover body 3, a heater 4 and a foam component 5. The turning beam of a refrigerator is usually arranged vertically, and has a high vertical height.
[0040] The first cover body 2 is disposed on one side of the intermediate frame 1 to form a first accommodating cavity 101;
[0041] The second cover body 3 is covered on the other side of the middle frame 1 to form a second accommodating cavity 102;
[0042] The heater 4 is disposed in the first accommodating cavity 101, on the inner wall of the first cover body 2 and extending to both ends of the first cover body 2 in the height direction;
[0043] The foam component 5 is disposed in the second accommodating cavity 102;
[0044] Both ends of the first cover body 2 in the height direction extend toward the second cover body 3 to form a first flange 21, the first flange 21 extends into the second accommodating cavity 102 and is arranged close to the inner wall of the second cover body 3, and the top wall and bottom wall of the second accommodating cavity 102 are respectively against the two first flanges 21.
[0045] In the above scheme, the heater 4 is arranged on the inner wall of the first cover body 2 and extends to both ends of the first cover body 2 in the height direction, which increases the contact area between the heater 4 and the first cover body 2, and is convenient for increasing the heat conducted from the heater 4 to the first cover body 2; the first flange 21 extends into the second accommodating cavity 102 and is arranged close to the inner wall of the second cover body 3, which increases the length of the first flange 21, and increases the contact area between the two first flanges 21 and the top and bottom walls of the second accommodating cavity 102, thereby increasing the heat transfer area at the upper and lower ends of the flip beam, thereby increasing the temperature at the upper and lower ends of the flip beam, and avoiding condensation at the upper and lower ends of the flip beam.
[0046] Both ends of the second cover body 3 in the height direction are bent toward the first cover body 2 to form second flanges 31, and the second flanges 31 are located outside the first flange 21 and abut against the first flange 21. The two second flanges 31 respectively form the top wall and bottom wall of the second accommodating cavity 102, and abut against the first flange 21, so as to increase the sealing performance of the flip beam. The two first flanges 21 respectively form the top wall and bottom wall of the first accommodating cavity 101.
[0047] The end of the second flange 31 extends to and is disposed close to the outer wall of the first cover 2. Increasing the length of the second flange 31 and the contact area between the second flange 31 and the first flange 21 can increase the temperature at both ends of the flip beam and improve the sealing of the flip beam.

[0058] The intermediate frame 1 is provided with a guide sleeve 15, and the hinge shaft of the first hinge 7 is passed through the guide sleeve 15. The intermediate frame 1 is provided with a fixing plate 13, and a torsion spring 14 is connected between the fixing plate 13 and the hinge shaft of the first hinge 7;
[0059] A limiting cavity is formed between the intermediate frame 1 and the second cover body 3, and part of the second hinge 8 is arranged in the limiting cavity. The second cover body 3 is provided with avoidance notches corresponding to the first hinge 7 and the second hinge 8 to facilitate the movement of the first hinge 7 and the second hinge 8. The hinge shaft of the first hinge 7 and the fixing plate 13 are both provided with mounting holes to facilitate the insertion of the two ends of the torsion spring 14. Two limiting grooves are provided on the intermediate frame 1 to facilitate the limiting installation of the fixing plate 13.
[0060] The outer side wall of the second cover body 3 is provided with a plurality of spaced anti-collision protrusions 9 in the height direction.
