Title:
FREE BUILT-IN REFRIGERATOR CAPABLE OF INCREASING DEGREE OF OPENING
Document Type and Number:
WIPO Patent Application WO/2021/037121
Kind Code:
A1
Abstract:
A free built-in refrigerator capable of increasing the degree of opening, comprising a box body (10), a door body (20), and a hinge assembly (30) connecting the box body (10) and the door body (20). The box body (10) comprises an accommodating chamber (S) and an outer side surface (13) adjacent to the hinge assembly (30) and on an extension section of a rotation path of the door body (20), the direction of the accommodating chamber (S) toward the outer side surface (13) is a first direction (X), and the hinge assembly (30) comprises a first hinge piece (31), a second hinge piece (32), and a switching assembly (40) connecting the first hinge piece (31) and the second hinge piece (32). During the opening of the door body (20), the first hinge piece (31) first moves relative to the switching assembly (40), then the second hinge piece (32) moves relative to the switching assembly (40), wherein, the hinge assembly (30) first drives the door body (20) to rotate in place relative to the box body (10), then drives the door body (20) to move away from the box body (10) in the first direction (X), and drives the door body (20) to continue to rotate in place. The free built-in refrigerator improves the degree of freedom of opening and closing the door body (20), and can generate a variety of motion trajectories to adapt to different application scenarios.
