Problems solved by technology
However, this suction-assisted mechanism mainly uses the elasticity of the elastic caliper (claw) material itself to achieve rebound. The elastic caliper (claw) is generally made of POM (polyoxymethylene resin / polyoxymethylene resin), and its elasticity will increase with the closing of the door. The number of times increases and gradually weakens, and repeated deformation will cause fatigue cracks or even aging of the material, and it is easy to break and damage. Therefore, the service life of this suction-assisted mechanism is short and its reliability is low.

Embodiment Construction
[0028] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0029] Please refer to Figure 1 to Figure 4 , the door suction mechanism of this embodiment is used in a refrigerator, which includes a box body 8 and a door body. For a refrigerator with only one door body, the door suction mechanism can be directly arranged under the door body. figure 1 As shown in the refrigerator with the refrigerating chamber door 6 and the freezing chamber door 7, the door can be set as the refrigerating chamber door 6, that is, the door suction mechanism can be arranged under the refrigerating chamber door 6 and the freezing chamber door 7. Above, of course, according to specific needs, the door body can also be set as the freezer door body 7 .
[0030] The box door suction aid mechanism in this embodiment includes a door hinge and a rolling part 5 , wherein the door hinge includes a mounting part 1 , a c...

The invention discloses a door auxiliary absorbing mechanism and a refrigerator. The mechanism comprises a door hinge, wherein the door hinge comprises a cantilever, a mounting part to be fixed on a refrigerator body, a pivot part for pivoting with a door body, and a rolling part arranged on the lower end face of the door body; the mounting part and the pivot part are arranged at two ends of the cantilever; an auxiliary absorbing rail which takes the pivot part as a rotating center and is matched with the rolling part is arranged on the upper end face of the cantilever; the cantilever comprises an inner side corresponding to the inside of the refrigerator body and an outer side corresponding to the outside of the refrigerator body; and the auxiliary absorbing rail comprises a minus grade section extending from the inner side to the outer side of the cantilever, and / or a minus grade section extending from an elevated position between the inner side and the outer side of the cantilever to the outside. The door auxiliary absorbing mechanism and the refrigerator can avoid damage caused by weakened elasticity or ageing of a material, so the reliability of the auxiliary absorbing mechanism is remarkably improved, and the service life is increased.
Description
technical field [0001] The invention relates to the field of household appliances, in particular to a suction-assisting mechanism for a box door and a refrigerator. Background technique [0002] At present, door hinges are mostly used for the connection between the door body and the box body of various household appliances such as refrigerators, so that users can flexibly open and close the door body. The door hinge generally includes a mounting part, a cantilever and a pivoting part. The mounting part is fixed on the box body, the cantilever extends from the mounting part, and the pivoting part is arranged at the free end of the cantilever and is pivotally connected with the door body. In order to prevent the user from applying enough pushing force when closing the door body and causing the door body to fail to close tightly, most home appliances also set up a suction-assisted mechanism between the door body and the door hinge, and the door body is closed to To a certain e...
