Description

Technical Field

[0001] The invention relates to the technical field of refrigeration devices, in particular to a reinforcing iron and a door body and a refrigeration device using the reinforcing iron. Background Art

[0002] Refrigerator, freezer and other refrigeration devices mainly include two parts: the box body and the door body. The box body and the door body are connected by a movable connecting part to realize the opening and closing of the door body. This movable connecting part is usually a hinge. As an important part of the overall structure of the refrigeration device, the hinge not only connects the door body and the box body, but also plays a supporting role in the process of opening and closing the door body. Since the door body of the refrigeration device is frequently opened and closed, the hinge plays an important role in the firmness, stability and accuracy of the refrigeration device during the opening and closing process.

[0003] The door body of the existing refrigeration device usually uses an integral plastic door frame, which is weaker than the aluminum frame and the sheet metal door frame. As the number of times the door is opened increases, the door body may deform. In order to increase the firmness and stability of the overall structure of the door body, the door body of the existing refrigeration device is usually connected to the hinge through a reinforcing iron. The hinge is located on the side of the door body, that is, the hinge is connected to the door frame of the door body. The outside of the door frame is the hinge, and the inside of the door frame is provided with a reinforcing iron at the connection between the hinge and the door body. The inside of the door frame also has a foaming layer. The side of the door body of the refrigeration device is hinged, door frame, reinforcing iron and foaming layer from outside to inside. Generally, the reinforcing iron is first fixed to the inside of the door frame by screws, and then foaming is performed to form a foaming layer in the foaming cavity between the door frame and the top glass plate. Finally, the hinge is fixed to the reinforcing iron inside the door frame by screws from the outside of the door frame.

[0004] As people's living standards continue to improve, higher requirements are placed on the aesthetics and practicality of refrigerators, freezers and other refrigeration devices, which makes the weight of the door body of the refrigeration device continue to increase; as the weight of the door body of the refrigeration device increases, the torque value of the hinge used in conjunction with it also increases, and the door body will be deformed by the hinge at the part where the reinforced iron connection is installed after the hinge is installed, resulting in an uneven surface of the door body and poor deformation of the door body, which seriously affects the aesthetics of the door body and the performance of the refrigeration device.

The door body 5 of the present invention has a hinge 7 on the outer side of the door frame 51, and a reinforcing iron 8 is arranged on the inner side of the door frame 51. The reinforcing component 2 of the reinforcing iron 8 penetrates into the foaming layer inside the door body 5 and is tightly connected to the foaming layer, which effectively supports the door body 5, and its structure is firm and has strong bearing capacity. Figure 6 The middle dashed line represents a structure that cannot be directly seen from this viewing angle, and is a structure that can be seen through the panel 52 .

[0042] See attached Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 and attached Fig. 9 A refrigeration device of the present invention comprises a box body 6, a door body 5 is provided on the box body 6, and the box body 6 and the door body 5 are connected by a hinge 7. The refrigeration device of the present invention is a refrigerator or a freezer, which can be a vertical box body 6 or a horizontal box body 6. The refrigeration device in this embodiment is a horizontal freezer, and the door body 5 is opened or closed by a hinge 7.

At this time, the required force is the largest, the torsion of the hinge 7 spring is also the largest, and the door body 5 is most likely to be deformed. In the present invention, under the action of the reinforcing iron 8, the reinforcing plate 21 effectively strengthens the performance of the reinforcing iron 8 through the mounting plate 1, and the support plate 23 fully decomposes the force generated by the door body 5 through the panel 52; on the one hand, the firmness and stability of the connection structure between the door body 5 and the hinge 7 are increased, and the structure of the door body 5 is effectively supported; on the other hand, the force generated by the torque during the opening and closing of the door body 5 is fully decomposed, especially at the maximum torque, so that the force borne locally by the door body 5 is greatly weakened, thereby preventing the deformation of the door body 5.
