风道组件、冰箱及其控制方法 技术领域
本发明涉及制冷装置领域，尤其涉及一种风道组件、冰箱及其控制方法。
背景技术
随着社会的发展，人们对生活品质要求越来越高。其中，人们在居家生活中对食物储藏的多元化和个性化要求越来越强烈，因此，应运而生了一种带变温室的冰箱，该种冰箱中变温室内的温度可单独调节，以满足用户储藏多种物品的需求。
现有的具有变温室的冰箱一般都是采用多制冷系统或者单系统多风门实现相应的功能。对于具有多制冷系统的冰箱而言，需要设置电磁阀，以在多制冷系统之间切换以分别给各制冷间室供冷，无法实现多制冷间室同时制冷，且多个蒸发器会占用冰箱的储物空间，使冰箱的储物空间减小，增大成本。对于单系统多风门的变温冰箱而言，变温室对应的风门需要设置得较大，才能满足全温区变温的功能，不利于风道的布局。
有鉴于此，有必要提供一种新的风道组件、冰箱及其控制方法以解决上述问题。

于一具体实施方式中，所述蒸发器室位于底部，所述第二进风口31位于所述第一进风口11的上侧。
具体地，结合图1、图2所示，所述风道组件10包括前盖板5、与所述前盖板5相配合的后盖板6，所述第一风道1以及所述第二风道3位于所述前盖板5与所述后盖板6之间，所述第一进风口11与所述第二进风口31均设于所述后盖板6上，所述第一风机2固定于所述后盖板6上与所述第一进风口11相对应的位置处，所述第二风机4固定于所述后盖板6上与所述第二进风口31相对应的位置处，能够简化所述风道组件10的内部结构，且便于组装。
进一步地，所述第二进风口31所在的平面位于所述第一进风口11所在的平面的后侧，从而，能够减小所述第一风机2对所述第二风机4的影响，防止第一风机2影响第二风机4的吸风量，即部分自所述蒸发器室出来的冷风在所述第二风机4的抽吸力的作用下直接进入所述第二进风口31内，不会受所述第一风机2的抽吸力的影响。
具体地，请参图3-图4所示，所述第二风机4包括蜗壳41、固定于所述蜗壳41上的风 机本体42，所述后盖板6上具有与所述蜗壳41相配合的蜗壳部，通过将所述蜗壳41固定于所述后盖板6上以将所述第二风机4固定于所述后盖板6上。
在所述第二风机4固定于所述后盖板6上后，所述蜗壳41与所述蜗壳部共同形成所述第二风道3，有利于引导冷风的流动，且所述第二风道3与所述第一风道1相隔热设置，能够防止第一风道1与第二风道3之间的温度互相影响。
具体地，所述第二进风口31设于所述蜗壳部上。
可以理解的是，所述第二风道3的出风口位于所述后盖板6的侧壁上，便于引导冷风流动至冷藏室内。
进一步地，所述风道组件10还包括设于所述第二风道3内的风门(未图示)，可以通过控制第二风机4以及风门来调节所述冷藏室内的温度，通过控制第一风机2来调节变温室内的温度，使变温室能够在较大的温区之间调节温度。
进一步地，请参图5-图6所示，所述风道组件10还包括位于所述前盖板5与所述后盖板6之间的隔热板7，所述隔热板7与所述后盖板6之间形成用以收容所述第一风机2的第一收容腔、用以收容所述第二风机4的第二收容腔，所述第一收容腔与所述第二收容腔之间通过所述隔热板7相隔热，能够减少第一风道1与第二风道3之间的相互影响。同时，所述隔热板7能够将蒸发器室、风道、变温室相互隔开，以防蒸发器室和/或风道对变温室内的温度造成影响。
进一步地，所述前盖板5上具有多个出风口，所述第一风道1连通所述第一收容腔与所述多个出风口，即，所述前盖板5上的多个出风口用以给变温室提供冷量，便于所述风道组件与冰箱之间的装配。
进一步地，沿所述第一收容腔与所述第二收容腔的排布方向，所述多个出风口包括位于所述第一收容腔的相对两侧的第一出风口51、第二出风口52，使变温室内的出风分布较为均匀，从而，使变温室内的温度也比较均匀。
对应地，所述第一风道1包括连通所述第一收容腔与所述第一出风口51的第一子风道12、连通所述第一收容腔与所述第二出风口52的第二子风道13，即，进入所述第一收容腔内的冷风分为两路自第一子风道12、第二子风道13分别进入所述变温室内。

同时，所述第一出风口51位于所述前盖板5上与所述前隔热板72的上下两端相对应的位置处，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子风道12，即，通过所述前隔热板72将所述第一子风道12与所述变温室相隔开，能够防止所述变温室与所述第一子风道12之间的互相影响。
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，自所述第一出风口51反流至所述第一子风道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，能够防止第一风机2蓄水结冰，影响所述第一风机2的运行。
进一步地，第二子风道13形成于第一收容腔远离第二收容腔一侧的隔热板7内，能够防止第二子风道13与所述变温室之间相互影响。

可以理解的是，所述第一制冷间室可以为所述变温室，所述第二制冷间室可以为所述冷藏室；当然，并不以此为限。
所述风道组件10的具体结构如上所述，于此，不再赘述。
本发明中的所述风道组件10设置于所述第一制冷间室的后侧，能够增大所述第二制冷间室的储物空间，解决用户对作为冷藏室的第二制冷间室空间需求大的问题。
具体地，所述冷藏室的保温层(未图示)中贯穿设有与所述第二风道3的出风口相对接的引导风道，所述冷藏室的冷藏内胆上设有冷藏出风口，所述引导风道连通所述冷藏出风口以及所述第二风道3，以将所述第二风道3内的冷风引导至冷藏室内，给冷藏室提供冷量。
进一步地，请参图7所示，本发明还提供一种控制上述的冰箱的控制方法，所述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，控制压缩机以及第二风机4启动，同时，控制第一风机2以预设低速运行。
具体地，“控制压缩机以及第二风机4启动”具体为，控制压缩机启动，同时控制第二风机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。
在所述第二风机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，所述第一风机2以预设低速运行，使所述第一风道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，也无法经第一风道1流经第一风机2以及第二风机4，能够防止第一风机2与第二风机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“控制压缩机以及第二风机4启动，同时，控制第一风机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，第一风机2以及第二风机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，在所述第一风机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，即使第一风机2持续运行，也无法给第一制冷间室内提供冷量，防止第一制冷间室内的食材冻坏。
“第一风机2以及第二风机4持续运行”具体指所述第一风机2以预设低转速持续运行，所述第二风机4以制冷模式下设定的转速持续运行。
在压缩机停机时，所述第一风机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，所述第二风机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，第一风机2以制冷模式下设定的转速运行，给第一制冷间室制冷，第二风机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，控制第一风机2以及第二风机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第一风机2启动，同时控制风门关闭所述第二风道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，第一风机2以及第二风机4以制冷模式下设定的转速运行即可。
综上所述，本发明中的风道组件10中将第二进风口31相较于第一进风口11靠后设置，从而，能够减小所述第一风机2对所述第二风机4的影响，防止第一风机2影响第二风机4的吸风量，即部分自所述蒸发器室出来的冷风在所述第二风机4的抽吸力的作用下直接进入所述第二进风口31内，不会受所述第一风机2的抽吸力的影响。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
