本发明中的所述风道组件10设置于所述变温室的后侧，能够增大所述冷藏室的储物空间，解决用户对冷藏室空间需求大的问题。
具体地，所述变温风道1位于所述隔热板7内，能够将所述变温风道1、蒸发器室、变温室之间通过隔热板7相互隔热，以防三者之间相互影响。
所述前盖板5具有位于所述冷藏风机4所在侧的第一变温出风口51、位于所述变温风机2远离所述冷藏风机4一侧的第二变温出风口52，对应的，所述变温风道1包括连通所述第一收容腔与所述第一变温出风口51的第一变温风道12、连通所述第一收容腔与所述第二变温出风口52的第二变温风道13，以使变温室内的出风比较均匀，有利于保鲜。
具体地，所述隔热板7包括与所述后盖板6围设形成所述第一收容腔与所述第二收容腔的后隔热板71、与所述后隔热板71围设形成所述第一变温风道12的前隔热板72；所述后隔热板71具有连通所述第一收容腔与所述第一变温风道12的连通口711，以使所述第一收容腔与所述第一变温风道12相连通。
同时，所述前盖板5上与所述前隔热板72的上下两端相对应的位置处均设有所述第一变温出风口51，所述后隔热板71上具有用以放置所述前隔热板72的凹槽，所述前隔热板72与所述凹槽共同形成所述第一变温风道12。
进一步地，所述后隔热板71与所述前隔热板72相对的一侧凸设有导流条712，所述导流条712的前端位于所述连通口711的前周缘所在的平面的前侧，从而，自所述第一变温出风口反流至所述第一变温风道12内的变温室内的水汽在接触所述导流条712后凝结成的水不会滴落至第一收容腔内，能够防止变温风机2蓄水结冰，影响所述变温风机2的运行。
进一步地，控制上述的冰箱的控制方法包括如下步骤：
在第二制冷间室需要制冷而第一制冷间室不需要制冷时，控制压缩机以及冷藏风机4启动，同时，控制变温风机2以预设低速运行。
具体地，“控制压缩机以及冷藏风机4启动”具体为，控制压缩机启动，同时控制冷藏风机4以制冷模式下设定的转速启动，从而能够给第二制冷间室提供冷量。
在所述冷藏风机4启动将所述蒸发器室的冷量输送至第二制冷间室内的同时，所述变温风机2以预设低速运行，使所述变温风道1内的空气朝向第一制冷间室内流动，使第二制冷间室内的回风即使经第一制冷间室的回风道进入第一制冷间室内，也无法经变温风道1流经变温风机2以及冷藏风机4，能够防止变温风机2与冷藏风机4凝结，造成封路堵塞。
于一具体实施方式中，所述预设低转速为800rpm。当然，并不以此为限。
进一步地，在“控制压缩机以及冷藏风机4启动，同时，控制变温风机2以预设低速运行”后，所述冰箱的控制方法还包括如下步骤：
判断第一制冷间室内的温度是否低于预设温度，若是，则控制压缩机停机，变温风机2以及冷藏风机4持续运行直至第一制冷间室到达开机温度或者第二制冷间室到达关机温度。
可以理解的是，在所述变温风机2以预设低速运行时，仍然能够将蒸发器室内的部分冷量提供给第一制冷间室，给第一制冷间室降温，故，需要时刻获取第一制冷间室内的温度，判断是否过冷，即，在第一制冷间室内的温度低于预设温度时，得出所述第一制冷间室内的温度过冷。此时，控制压缩机停机，即使变温风机2持续运行，也无法给第一制冷间室内提供冷量。
“变温风机2以及冷藏风机4持续运行”具体指所述变温风机2以预设低转速持续运行，所述冷藏风机4以制冷模式下设定的转速持续运行。
在压缩机停机时，所述变温风机2持续运行，能够使第一制冷间室内的温度较低的回风循环至蒸发器室内，所述冷藏风机4持续运行，能够将循环至蒸发器室内的温度较低的回风输送至第二制冷间室内，即，能够将所述第一制冷间室内的冷量提供给第二制冷间室，给第二制冷间室降温。
在第一制冷间室到达开机温度后，控制压缩机启动，变温风机2以制冷模式下设定的转速运行，给第一制冷间室制冷，冷藏风机4以制冷模式下设定的转速运行给第二制冷间室制冷；或者在第二制冷间室达到关机温度后，控制变温风机2以及冷藏风机4停机。
可以理解的是，在第一制冷间室需要制冷，而第二制冷间室不需要制冷时，可以控制压缩机以及变温风机2启动，同时控制风门关闭所述冷藏风道3，从而，只给所述第一制冷间室提供冷量。
在第一制冷间室与第二制冷间室均需要制冷时，控制压缩机启动，变温风机2以及冷藏风机4以制冷模式下设定的转速运行即可。
综上所述，本发明中的冰箱将冷藏风机4设置于变温风机2远离蒸发器室的一侧，使所述冷藏风机4距所述蒸发器室较远，能够避免冷藏风机4排水口因蒸发器室的冷量发生冰堵。
