Description

电冰箱的吸气端口结构
本发明涉及到电冰箱的吸气端口结构，尤其是用于电冰箱的冷藏室的吸气端口的结构，使得当冷藏室的门被迅速关闭时，冷冻室的门不被打开。
通常，如图1所示，电冰箱被分成冷藏室10和冷冻室20。压缩致冷剂的压缩机(未示出)安装在电冰箱的底部，而蒸发器30安装在冷冻室20的后边。由压缩机压缩的致冷剂循环流动，并且通过循环致冷剂的作用，蒸发器30冷却周围的空气。由蒸发器30冷却的冷空气，通过冷空气的输送通路提供给冷藏室10和冷冻室20。
为了保持在冷藏室10和冷冻室20之间的温度差，隔热部件32安置在冷藏室10和冷冻室20之间。在隔热部件32中，形成一个与冷藏室10、冷冻室20和蒸发器30连通的吸气通路。吸气通路34用防冻胶板18分开，并且延伸到冷藏室10和冷冻室20，以吸取热空气并且把热空气送到蒸发器30。门36和38安装在电冰箱前面的冷藏室10和冷冻室20上。
通过吸气端口40和吸气通路34，在冷藏室10里的热空气被提供给蒸发器30。为了使热空气能够顺利地提供给蒸发器30，常规的电冰箱配备有如图1和2所示的吸气端口40。吸气端口40具有一个上窄下宽的梯形的截面形状。
然而，在配备有上述形状的吸气端口40的常规的电冰箱中，存在一个问题，该问题与冷冻性能无关。换言之，当冷藏室10的门36迅速关闭时，冷冻室20的门38经常打开，而冷藏室10中的热空气通过吸气端口40顺利地提供给蒸发器30。当门36被迅速关闭时，在冷藏室10里面的压力立即增加，并通过吸气端口40和气体管道34，传递到冷冻室20。结果，冷冻室20里面的压力也立即增加，使得门38经常被打开。
为了解决这个问题，本发明的目的是要提供一种冷空气循环装置，由此，当冷藏室的门被迅速关闭时，冷冻室的门不被打开。
为了达到本发明的目的，配备一个可安置在电冰箱里的冷空气循环装置，电冰箱具有：一个冷藏室、一个冷冻室、一个分隔冷藏室和冷冻室的分隔部分，一个安置在冷冻室后面的蒸发器、以及一个循环空气的风扇。
冷空气循环装置包括：
第一和第二吸气端口，用于吸取冷藏室和冷冻室里面的热空气并将热空气输送到蒸发器；以及
通路装置，包括用于把冷藏室中的热空气提供给蒸发器的第一吸气通路，和用于把冷冻室里的热空气提供给蒸发器的第二吸气通路，第一吸气通路与第一吸气端口相通并且形成在分隔部分内，第二吸气通路与第二吸气端口相通并且形成在该分隔部分内。
第一吸气端口具有一个上面窄下面宽的截面形状，并且，至少有一个台阶形成在从上面部延伸到下面部的倾斜面上。
通过参考附图对优选实施例的详细描述，本发明的上述目的和其它的优点将会变得更加明显，其中：
图1是说明配备有常规的吸气端口的吸气通路结构的局部截面图；
图2是沿图1中的箭头A的方向的吸气端口的平面视图；
图3是说明与备有按照本发明的吸气端口的吸气通路结构的局部截面图；以及
图4是沿图3中箭头A的方向的吸气端口的平面视图。
下面参考图3和4详细描述按照本发明的冷空气循环装置的优选的实施例。在该实施例中，与现有技术相同的标号用来指明相同的部件。
如前面所述，一台电冰箱被分成冷藏室10和冷冻室20。由压缩机压缩的致冷剂进行循环流动，并且，通过循环的致冷剂的作用，蒸发器30冷却周围的空气。由蒸发器30冷却的冷空气，通过冷空气输送通路提供给冷藏室10和冷冻室20。用于循环空气的风扇(未示出)安装在电冰箱的壳体中。
为了保持在冷藏室10和冷冻室20之间的温度差，将隔热部件32安置在冷藏室10和冷冻室20之间。在隔热部件32中，形成一个连通冷藏室10、冷冻室20和蒸发器30的吸气通路34。吸气通路34由防冻胶板18分开，并且延伸到冷藏室10和冷冻室20，用来吸取热空气并且将热空气输送到蒸发器30。防冻胶板18用长方形的隔热部件32制成。
通过吸气端口50和吸气通路34将冷藏室10中的热空气提供给蒸发器30。为了使热空气平稳地提供给蒸发器30，该实施例的吸气端口50具有上面窄下面宽的阶梯式的截面形状，如图3和4所示。
如图所示，台阶形成在吸气端口50的周边，并且可形成两个或多个台阶。由吸气通路34的结构和长度、吸气端口50和类似物的横截面积决定台阶的个数。
在具有按照本发明的吸气端口结构的电冰箱中，冷藏室10中的热空气能通过吸气端口50和吸气通路34平稳地提供给蒸发器30，这是因为吸气端口50具有上面窄下面宽形状。另外，由于按照本发明的吸气端口50具有一个或多个台阶，所以，在冷藏室10里瞬间增加的压力，在快速传递到冷冻室20时，被台阶阻挡。因此，虽然冷藏室10的门36被迅速关闭，在对门36迅速关闭的回应中，也不会发生冷冻室20的门38被打开的情况。
当参考本发明的实施例对本发明作具体说明和描述时，熟悉该专业技术领域的人员会明白：在不脱离权利要求书限定的本发明的精神和范围的情况下，本发明可在形式和细节上有各种变化。
