Document Type and Number:
WIPO Patent Application WO/2024/051860
Kind Code:
A1
Abstract:
The present invention provides built-in household appliance hinges and a refrigerator. The built-in household appliance hinges are mounted between household appliance door bodies and a household appliance cabinet body, and each comprise a hinge body, wherein one end of the hinge body is fixed to the household appliance cabinet body, and the other end thereof is provided with a cam; each household appliance door body is provided with a track frame in a regular triangle shape; the cam comprises two short outer circular-arc edges that have mirror symmetry therebetween, and two long outer circular-arc edges that have mirror symmetry therebetween, the long outer circular-arc edges being tangent between the same sides of the two short outer circular-arc edges; during the process of rotation of each household appliance door body relative to the household appliance cabinet body, an inner side wall of the track frame moves along an outer side wall of the cam; and during the process of movement, the outer side wall of the cam maintains contact with and keeps tangent to the inner side wall of the track frame at three points. The refrigerator comprises the household appliance cabinet body and the household appliance door bodies, which have the above hinges mounted therebetween. The present invention has a simple structure, is convenient to manufacture, and makes the household appliance door bodies retract inwards when the household appliance door bodies are opened, thereby effectively preventing the household appliance door bodies from interfering with a deep and narrow space or other objects in the deep and narrow space when being opened.
