In addition, a fresh-keeping container for storage is formed at the lowermost part of the refrigerating chamber, and the air blown by the fan is blown to the refrigerating chamber through the air passage formed on the rear side of the refrigerating chamber, while part of the air blown in the air passage does not pass through the refrigerating chamber. The refrigerating compartment is directly blown to the fresh-keeping container, so that the cold air is directly supplied to the stored items such as meat. In this way, the internal temperature of the fresh-keeping container is lower than the indoor temperature of the refrigerator compartment (for example, it can be set to about 0° C.). Moreover, foodstuffs, such as stored meat, can be preserved in a fresh-keeping container.
然而，在前述专利文献1所记载的冰箱中，从长期良好地保证肉等被储藏物的新鲜度的角度出发，还存在改善的余地。However, in the refrigerator described in the aforementioned Patent Document 1, there is still room for improvement from the viewpoint of ensuring the freshness of the stored objects such as meat well for a long period of time.
具体而言，在专利文献1中所记载的发明中，从风路直接向保鲜容器的内部吹送空气，从而冷却被储藏物。因此，被储藏物的温度取决于吹过它的空气量，因此被储藏物的温度容易上下浮动，而使保鲜容器内部的温度范围较大。若被储藏物的温度上升，则会产生水滴，若下降则水滴结成霜，因此存在难以长期保持被储藏物的新鲜度的问题。Specifically, in the invention described in Patent Document 1, air is directly blown into the fresh-keeping container from the air passage, thereby cooling the storage object. Therefore, the temperature of the object to be stored depends on the amount of air blown through it, so the temperature of the object to be stored tends to fluctuate up and down, and the temperature range inside the fresh-keeping container is wide. When the temperature of the storage object rises, water droplets are generated, and when the temperature falls, the water droplets form frost, so there is a problem that it is difficult to maintain the freshness of the storage object for a long time.
有鉴于此，有必要对现有的冰箱予以改进，以解决上述问题。In view of this, it is necessary to improve the existing refrigerators to solve the above problems.
