Description

分路送风装置及冰箱Shunt air supply device and refrigerator 技术领域Technical field
本发明涉及冰箱储物领域,特别是涉及一种分路送风装置及冰箱。The invention relates to the field of refrigerator storage, in particular to a split air supply device and a refrigerator.
背景技术Background technique
目前,风冷冰箱通过内置的蒸发器产生冷风,冷风通过风道循环流动至冰箱的各个储物间室实现制冷。对于风冷冰箱,食物的保鲜性能很大程度取决于储物间室内气流循环是否合理。如果冷风经风道随机流动,容易造成进入各储物间室内的风量过多或不足,使储物间室内的温度分布不均衡,冰箱的运行效率也会降低。因此,有必要对进入各储物间室内的冷风进行精确地流向分配和流量控制。同样地,为优化存储空间,单个储物间室一般会被搁物架或者抽屉等搁物装置分隔为多个细化的储物空间,根据存放物品的多少,每一个储物空间所需要的冷量也是不同的,因此,冷风不加控制地直接从储物间室的某处直接进入储物间室内,会造成部分储物空间过冷,部分储物空间冷量不足的问题。At present, the air-cooled refrigerator generates cold air through a built-in evaporator, and the cold air is circulated through the air duct to the respective storage compartments of the refrigerator to achieve cooling. For air-cooled refrigerators, the freshness of food depends largely on whether the indoor air circulation in the storage room is reasonable. If the cold air flows randomly through the air passage, it is easy to cause too much or insufficient air flow into each storage room, so that the temperature distribution in the storage room is not balanced, and the operating efficiency of the refrigerator is also lowered. Therefore, it is necessary to accurately flow the distribution and flow control of the cold air entering the interior of each storage room. Similarly, in order to optimize the storage space, a single storage room is generally divided into a plurality of refinement storage space by a shelf device such as a rack or a drawer, and each storage space is required according to the amount of the stored items. The cooling capacity is also different. Therefore, the cold air directly enters the storage room directly from somewhere in the storage room without control, which may cause some storage space to be too cold and some storage space to have insufficient cooling capacity.
