Door body suction assisting device and refrigerator

Abstract

The embodiment of the invention relates to the field of appliances, in particular to a door body suction assisting device and a refrigerator and is used for increasing the suction assisting force provided by a suction assisting device body. According to the embodiment, the door body suction assisting device comprises a hinge plate and a suction assisting device body, wherein the hinge plate is fixedly connected to a refrigerator body and provided with a suction assisting arm, and the two side surfaces of the suction assisting arm are provided with protrusions; and the suction assisting device body is fixedly connected to a door body, hinged to the hinge plate and provided with bent arms capable of generating elastic deformation. When the door body is closed, the bent arms are located on the two sides of the suction assisting arm correspondingly and are matched with the protrusions of the suction assisting arm correspondingly to generate elastic deformation. Thus, in the door body closing process, two contact surfaces exist between the bent arms of the suction assisting device body and the protrusions of the suction assisting arm, and the suction assisting device body can produce two suction assisting forces through the two protrusions and the two bent arms, so that the suction assisting forces of the suction assisting device are increased.

Description

technical field [0001] The embodiments of the present invention relate to the field of home appliances, in particular to a door body suction-assisting device and a refrigerator. Background technique [0002] Refrigerators often have the situation that the door is not closed tightly when opening and closing the door. Once the refrigerator door is not closed tightly, it will not only cause waste of electricity, but also accelerate the deterioration of food in the box. In order to enhance the airtightness of the refrigerator door, a suction aid is generally used in the prior art. [0003] figure 1 It exemplarily shows a structural schematic diagram of a refrigerator equipped with an arm buckle type suction device in the prior art, Figure 1a Exemplary figure 1 A partially enlarged schematic diagram of the middle area 100, Figure 1b exemplarily shows figure 1 Schematic diagram of the structure of the arm button suction device when the door is closed. Such as figure 1 , ...

AI Technical Summary

Problems solved by technology

It can be seen that in the prior art, only the point B0 is used to block, and the blocking force is relatively poor. In daily life, the air in the door seal air bag of the door body 1101 is heated and expands, and the door body 1101 will often be bounced open, thereby causing the door of the refrigerator 1100 to open. Body 1101 is not tightly closed and concealed

When doing a high-temperature defrosting test on the refrigerator 1100, since the air in the door seal air bag of the door body 1101 is heated and expanded, and the blocking effect of the suction aid 1201 is small, the door body 1101 will be automatically bounced open by the door seal air bag at this time, seriously Affect the cooling effect of the refrigerator 1100, increase power consumption, and increase condensation at the same time

[0006] Several possible solutions are to increase the size of the protrusion of the suction aid arm 1205, or increase the bending degree of the hook of the suction aid 1201, both of which will increase the amount of deformation of the suction aid 1201 during door opening or closing, In this way, it is easy to increase the degree of wear of the suction aid 1201, and even cause the failure of the suction aid 1201
