有鉴于此，业内有必要提供一种有效的技术方案以解决上述问题。
发明内容

另外本发明还提供了一种与以上冰箱相匹配的冷冻冷藏功能转换的控制方法，其包括以下步骤：
S1：用户选择是否将冷冻室的功能由冷冻转变为冷藏，其中冷冻功能相对冷藏功能具有更低的制冷温度；
S2：若需要将冷冻室的功能由冷冻转变为冷藏，进入步骤S3；若不需要将冷冻室的功能由冷冻转变为冷藏，则进入步骤S4；

具体实施方式
以下将结合附图所示的各实施方式对本发明进行详细描述，请参照图1至图4所示，其为本发明的一些较佳实施方式。
如图1-3所示，本发明的一种冰箱包括：冷藏室1、冷冻室2、制冷循环系统(图中未示出)、控制系统(图中未示出)，制冷循环系统具有压缩机、冷凝器及蒸发器(图中未示出)，控制系统用于控制冰箱的运行。
以上结构对于本领域技术人员而言较为容易理解，其为冰箱的一些基本结构，其中，制冷循环系统还包括膨胀机构、循环管道及作为冷热交换核心的冷媒，制冷循环系统用于为冰箱制冷提供制冷冷气，具体其它在此不作过多陈述。
如图所示，本实施例的冰箱还包括风道系统以及与该风道系统相匹配的风机3，其中风道系统具有冷藏室风道支路42及冷冻室风道支路41，风机3将由制冷循环系统制备的冷气输送至冷藏室风道支路42及冷冻室风道支路41中，冷藏室风道支路42与冷冻室风道支路41具有同一风道风门51，即风道风门51同时控制冷藏室风道支路42与冷冻室风道支路41中的冷气进入量。风道风门51具有若干档位，其处于不同档位时，进入冷藏室风道支路42及冷冻室风道支路41中冷气的流量比不同；与风道风门51匹配的设置有风门状态检测机构，风门状态检测机构用以检测并向控制系统反馈风道风门51的档位状态。
具体在本实施例中，风道风门联动的控制控制冷藏室风道支路42与冷冻室风道支路41的冷气入口：当增强冷藏室风道支路42的冷气进入量时，冷冻室风道支路41的冷气进入量相应减弱；当减弱冷藏室风道支路 42的冷气进入量时，冷冻室风道支路41的冷气进入量相应增强。其中，冷冻室风道支路41的末端与冷冻室2联通，冷藏室风道支路42的末端与冷藏室1联通。
在本实施例中，风道风门51具有第一档位及第二档位；风道风门51处于第一档位时，即如图1所示，进入冷冻室风道支路41中冷气流量占输送至风道系统中冷气总流量的比值具有最小值W1；风道风门51处于第二档位时，即如图2所示，进入冷冻室风道支路41中冷气流量占输送至风道系统中冷气总流量的比值具有最大值W2。如图所示，箭头所示方向为冷气流动方向，箭头密度大致展示冷气的分布(不作为冷气准确分配的依据)。如图所示，当风道风门51处于第一档位时，冷冻室风道支路41的冷气入口变小，冷藏室风道支路42的入口变大，相应的即可减小进入冷冻室2中的冷气流量，基于此，可以将本发明中的冷冻室功能由冷冻转变为冷藏；相反，当风道风门51处于第二档位时，进入冷冻室风道支路41中的冷气流量最大，此时冷冻室保持正常冷冻功能。
当然，为了使冰箱具有更多的选择功能，本发明的风道风门51还具有第三档位，如图3所示，风道风门51处于第三档位时，进入冷冻室风道支路41中冷气流量占输送至风道系统中冷气总流量的比值为W3，其中，W1<W3<W2。此时，在保持冷藏室1的冷藏温度前提下，冷冻室2内部的温度比正常冷冻时(风道风门51处于第二档位)的温度高，如此可以满足一些用户软冷冻的需求，能够降低冷冻能耗。
在一些具体实施方式中，风道风门51通过旋转实现控制进入冷冻室风道41中冷气的流量，风门状态检测机构为电位器52。参考图1至图3，其中风道风门51以转轴的方式设置在冷藏室风道支路42与冷冻室风道支路41入口交界处，并与电位器52联动，风道风门51旋转时，电位器52的阻值会相应变化，该变化的信号可反馈至控制系统，并由控制系统发出相应动作指示，具体参考本发明冰箱的控制方法。
当然，在其它一些实施例中，风道风门52亦可以设置为其它形式，例如采用“移门式”等结构(一侧冷气入口变大的时候，另一侧冷气入口相应变小)，以能够实现以上冷气流量比例调节动作为基本原则；风门状态检测机构亦可以采用其它机构，以能够实现风道风门52状态检测为原则。
与以上实施例相对应，本实施例提供了一种冰箱的冷冻冷藏功能转换的控制方法，可参考图4，其具体包括以下步骤：
S1：用户选择是否将冷冻室的功能由冷冻转变为冷藏，其中冷冻功能相对冷藏功能具有更低的制冷温度；
S2：若需要将冷冻室的功能由冷冻转变为冷藏，进入步骤S3；若不需要将冷冻室的功能由冷冻转变为冷藏，则进入步骤S4；
S3：将风道风门设置于第一档位，风门状态检测机构将此时风道风门的状态反馈至控制系统，控制系统控制冰箱的冷冻室按冷藏程序运行；
S4：将风道风门设置于第二档位，风门状态检测机构将此时风道风门的状态反馈至控制系统，控制系统控制冰箱的冷冻室按冷冻程序运行。
在本实施例中，冷藏室1内部设置有检测冷藏室1内部温度的冷藏温度检测器(图中未示出)，冷冻室2内部设置有检测冷冻室2内部温度的冷冻温度检测器(图中未示出)。以上步骤S3中冷冻室按冷藏程序运行时，控制系统根据冷冻温度检测器检测的温度信号控制压缩机启动与停止，压缩机启动与停止时的温度由冷藏温度范围确定，风机的运转由压缩机启动与停止的信号及冷藏温度检测器检测的温度信号控制。
具体的，在冷冻室2按冷藏程序运行时，冷冻温度检测器检测的温度高于冷藏温度范围的最高温度时，压缩机启动，制冷循环系统开始制冷，风机3将冷气导入风道系统中；冷冻温度检测器检测的温度低于冷藏温度范围的最低温度时，压缩机停止，制冷循环系统停止制冷。
由于压缩机的启动与停止是根据冷冻室2内部的冷冻温度检测器检测 的温度信号进行调节，信号的判断节点是冷藏温度范围两端值，可以将冷冻室的功能有冷冻转变为冷藏。例如，若冷藏温度为4-8℃范围，冷冻温度检测器检测的温度高于8℃时，压缩机启动；冷冻温度检测器检测的温度低于4℃时，压缩机停止；另外，风机3导入的冷气是按一定的比例分别进入冷藏室1和冷冻室2，处于第一档位的风道风门51可以保证冷冻室2的冷冻功能转变为冷藏功能后，冷藏室依旧具有较为合适的冷藏效果。
理论上，冷冻室2的冷冻功能转变为冷藏功能后，冷藏室1与冷冻室2可以有相同的冷藏温度范围，但在实际应用阶段，可以允许冷藏室1与冷冻室2内部的冷藏温度具有小范围的差异，例如：冷藏室实际冷藏温度范围为4-8℃，冷冻室实际冷藏温度范围为2-6℃。
另外，在冷冻室按冷藏程序运行时，压缩机启动时，风机3开始运转；压缩机停止后，风机3根据冷藏温度检测器检测的温度信号控制。具体的，压缩机停止后，若冷藏室温度检测器检测的温度高于某一温度值时(该温度值一般处于冷藏范围温度内，可以是范围端值，亦可以是中间适当值)，风机需要继续运转一段时间才停止，以将残余的冷气完全输送至冰箱内部，进一步使得冷藏室温度降低。在另一些实施方式中，风机的运转完全由压缩机启动与停止的信号控制，与冷藏温度检测器检测的温度信号无关。
在冷冻室2按冷冻程序运行时，冰箱冷藏室与冷冻室分别实现冷藏、冷冻功能，控制系统根据冷藏温度检测器检测的温度信号控制压缩机启停，风机的运转由压缩机启动与停止的信号控制。具体的，当冷藏温度检测器检测的温度高于冷藏温度范围的最高温度时，压缩机启动，制冷循环系统开始制冷；所述冷藏温度检测器检测的温度低于冷藏温度范围的最低温度时，压缩机停止，制冷循环系统停止制冷。
例如，若冷藏温度为4-8℃范围，冷藏温度检测器检测的温度高于8℃时，压缩机启动；冷藏温度检测器检测的温度低于4℃时，压缩机停止。 此时，由风机3导入的大量冷气进入冷冻室，在冷藏室1处于冷藏温度范围时，冷冻室2相对冷藏室具有更低的温度范围。在一些具体设计中，冷冻室的温度可以低于-18℃。
此外，如以上冰箱的具体结构所述，本发明所涉及的冰箱风道风门51还可以具有第三档位，参考以上可以推理，当风道风门51设置在第三档位上时，冷冻室可以实现软冷冻的效果，即冷冻室2的制冷温度处于冷藏温度与冷冻温度之间。例如，正常冷冻的温度范围低于-18℃，正常冷藏范围高于0℃，此时冰箱的软冷冻温度范围可以处于两者之间，例如-7℃至-1℃，如此可以较好满足用户的多功能需求。冰箱冷冻室处于软冷冻功能时，其具体的控制过程可以参考冷藏过程。
此外，本发明中所涉及的冷藏温度检测器及冷冻温度检测器均为温度传感器，其可以实时检测冷藏室1及冷冻室2内部的温度并反馈给控制系统。
