Automatic refrigerator door opening and closing device
The invention belongs to the technical field of household appliances, and particularly relates to an automatic refrigerator door opening and closing device. The automatic refrigerator door opening andclosing device comprises a magnetic ejection mechanism, an upper magnetic suspension mechanism, a lower magnetic suspension mechanism and a rotary execution mechanism. When the magnetic ejection mechanism opens a door, ejection force is provided by utilizing the principle that like magnetic poles are repelled with each other, and attraction is provided by utilizing the principle that opposite magnetic poles are attracted to each other when the door is closed. The upper magnetic suspension mechanism and the lower magnetic suspension mechanism jointly provide upward magnetic force for a refrigerator door body, the mechanical friction resistance is reduced, and the burden of the rotary execution mechanism is reduced. The rotary execution mechanism drives the refrigerator door body to rotaterelative to a refrigerator body, and opening and closing of the refrigerator door body are completed. The overall design is simplified, the manufacturing cost is reduced, and the overall reliability is improved; and besides, the friction force between hinge pairs of the refrigerator door body is greatly reduced, the working noise of the actuation mechanism is reduced, the silent design is realized, and the strict noise requirements of household appliances such as refrigerators are met.
本发明属于家电技术领域，具体涉及一种冰箱门自动开关装置。该装置包括磁力顶出机构、上磁力悬浮机构、下磁力悬浮机构、旋转执行机构。磁力顶出机构开门时利用同性磁极相斥原理提供顶出力，关门时利用异性磁极相吸原理提供吸引力。上磁力悬浮机构和下磁力悬浮机构共同给冰箱门体提供向上的磁力作用，减轻机械摩擦阻力，减小旋转执行机构的负担。旋转执行机构驱动冰箱门体相对冰箱箱体旋转，完成冰箱门体的开关。本发明简化整体设计，降低了制造成本，提高了整体可靠性；另外，大幅度的减小了冰箱门体铰链副之间的摩檫力，降低了执行机构的工作噪音，实现了静音化设计，满足冰箱等家电严苛的噪音要求。
