可选地，所述导风结构包括所述压机仓靠近所述进风口的侧壁；或者，所述导风结构是设置在所述压机仓内的导风板。
可选地，所述压机仓的所述侧壁自底端至顶端逐渐朝着靠近所述接水盘的方向倾斜。
可选地，所述冰箱还包括风筒，所述风筒内形成有风腔，所述风筒的外周壁与所述压机仓的圆周壁抵接，以使所述压机仓内的空气全部流经所述风腔；所述冷凝器设置在所述风腔中并且与所述风筒嵌合，以将所述压机仓分割成所述压机室和所述蒸发室。
可选地，所述冷凝风机设置在所述风腔中；和/或，所述冷凝风机设置在所述冷凝器远离所述接水盘的一侧。
基于前文的描述，本领域技术人员能够理解的是，在本发明前述的技术方案中，在冰箱的冷量变化程度达到了预设冷量变化要求的同时或之后，通过使冷凝风机降低转速，使得冷凝装置的风冷效率降低，进而使得冷凝装置的温度升高，将更多的热量传递给接水盘内的冷凝水，对冷凝水进行加热，促进冷凝水的蒸发。因此，本发明在冰箱产生冷凝水的速率过快或者已经产生了较多冷凝水时，能够促进冷凝水的蒸发，有效地避免了出现冷凝水溢出接水盘的情形，进而避免了出现冷凝水流到冰箱周围的地面上的情形，提升了用户的使用体验。
进一步，通过将压缩机和接水盘分别设置在冷凝器的两侧，以及将冷凝 管的至少一部分设置在接水盘内，避免了冷凝器与接水盘在竖直方向上的叠加，有效地降低了冷凝器最顶端距离地面的高度，从而降低了压机仓的高度，进而增加了冰箱的储藏室的可用容积。
进一步，通过在压机仓内设置导风结构，并将导风结构配置成，将从进风口进入散热风道内的空气引导至接水盘内，使得进入压机仓内的空气在流经蒸发器之前先流向接水盘，提升了接水盘内冷凝水的蒸发速率。
再进一步，通过在冷凝器与压机仓的散热风道之间设置风筒，并使风筒的外周壁与压机仓的圆周壁抵接，以及使冷凝器嵌合到风筒中，使得进入压机仓的空气都能够流经冷凝器(包括，使空气中的大部分贯穿冷凝器，一小部分从冷凝器的周围吹拂而过)，提升了空气对冷凝器的冷却效率。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

具体实施方式
本领域技术人员应当理解的是，下文所描述的实施例仅仅是本发明的一部分实施例，而不是本发明的全部实施例，该一部分实施例旨在用于解释本发明的技术原理，并非用于限制本发明的保护范围。基于本发明提供的实施例，本领域普通技术人员在没有付出创造性劳动的情况下所获得的其它所有实施例，仍应落入到本发明的保护范围之内。

此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，还可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
图1是本发明一些实施例中冰箱的间室分布情况示意图，图2是本发明一些实施例中制冷系统的主要构件的连接情况示意图。需要说明的是，图2中示出的仅仅是制冷系统的主要构件，实际上，冰箱的制冷系统还包括控制阀、管路等其他结构。
如图1和图2所示所示，在本发明的一些实施例中，冰箱主要包括机体 1、压缩机2、冷凝组件3、冷媒降压构件4、蒸发器5、接水盘6和冷凝风机7。其中，压缩机2、冷凝装置3、冷媒降压构件4和蒸发器5流体连接到一起，以使冷媒能够按照压缩机2、冷凝装置3、冷媒降压构件4和蒸发器5的顺序依次循环流动。其中，接水盘6用于盛接冰箱的冷凝水和/或化霜水，冷凝风机7用于对冷凝装置3进行风冷。
需要说明的是，降压构件4可以是毛细管，也可以是具有节流功能和/或降压功能的构件。
进一步，冷凝装置3的一部分位于接水盘6内，以通过该一部分加热接水盘6内的冷凝水和/或化霜水。
进一步，冰箱还包括排水管(图中未标记)，排水管的一端通向制冷室12，排水管的另一端延伸至接水盘6，以便使制冷室12内的冷凝水和/和/或化霜水通过排水管流动到接水盘6内。
如图1所示，机体1上设置有压机仓11、制冷室12和储物室13。其中，压机仓11位于机体1的底部，至少用于布置压缩机2、冷凝装置3和接水盘6。制冷室12至少用于布置蒸发器5。储物室13用于盛放食材。
本领域技术人员能够理解的是，冰箱在工作的过程中所产生并流动到接水盘6内的冷凝水与接水盘6内蒸发掉的冷凝水会达到一个动态平衡的关系。在该动态平衡中，接水盘6内的冷凝水不会因过多而溢流出接水盘6。但是，当冰箱在较大的制冷功率下持续运行时，或者对蒸发器5进行了除霜之后，接水盘6内的冷凝水和/或化霜水会瞬间增多，容易溢流出接水盘6。可见，接水盘6内的冷凝水和/或化霜水会瞬间增多时，都会使冰箱的冷量变化程度较大。
进一步，为了避免接水盘6内的冷凝水和/或化霜水瞬间增多时溢出接水盘6，需要加快接水盘6内液体的蒸发。为了实现该目的，本发明在冰箱检测到其冷量变化程度达到了预设冷量变化要求的同时或之后，通过降低冷凝风机7的转速，来降低冷凝装置3的风冷效率，进而通过冷凝装置3通过位于接水盘6内的一部分加热接水盘6内的冷凝水和/或化霜水，促进接水盘6内液体的蒸发。
其中，冷量变化程度表示冰箱的制冷室12和/或储藏室13热能的变化程度。预设冷量变化要求表示制冷室12和/或储藏室13的热能变化使接水盘6内液体达到了溢出接水盘6的程度，其具体数据会随着冰箱的具体参数和性 能而发生变化。本领域技术人员可以针对不同型号的冰箱通过多次试验获得该具体数据。
本领域技术人员还能够理解的是，在冰箱开门时，在压缩机2工作时，在蒸发器5化霜时，在冷藏室13内增加或减少食材时，都会导致制冷室12和/或储藏室13的热能发生变化。
具体地，在冰箱开门时，环境中的部分热空气会流动到储藏室13内，储藏室13内的部分冷空气也会流动到环境中，从而导致冷藏室13内的热能增加，出现温升。
在压缩机2工作时，制冷系统会对蒸发器5进行制冷，从而冷却制冷室12内的空气，制冷室12内的冷空气流动到储藏室13内会降低储藏室13的温度。即，制冷室12和储藏室13内的热能都减少。
在蒸发器5化霜时，制冷系统会对蒸发器5进行加热，从而加热制冷室12内的空气，制冷室12内的冷空气流动到储藏室13内会增加储藏室13的温度。即，使得制冷室12和储藏室13内的热能都增加。
在冷藏室13内增加会减少食材时，尤其是冷藏室13内增加了食材时，由于食材的温度通常会高于冷藏室13的温度，从而导致食材向冷藏室13释放热量，使冷藏室13的温度升高。
本领域技术人员还能够理解的是，在制冷室12和/或储藏室13的热能发生了变化以后，为了使储藏室13维持正常的工作状态，制冷系统都需要对蒸发器5进行制冷。在此过程中，蒸发器5会使空气中的水蒸气液化成冷凝水，在此过程中产生的冷凝水以及蒸发器5化霜过程中产生的化霜水最终会流动到接水盘6内，导致接水盘6内的液面上升。
进一步，为了保证冷量变化程度的检测精度，在本发明的一些实施例中，通过判断预设的至少两种参数是否都达到了各自对应的参数阈值，来判断冰箱的冷量变化程度是否达到了预设冷量变化要求。
其中，至少两种参数包括冰箱的累积开门时间、压缩机2的累积运行时间、放入至储藏室13内食材的重量、放入至储藏室13内食材的温度、放入至储藏室13内食材的种类、储物室13的当前温度与预设温度之间的差值、蒸发器5的化霜次数等。
可选地，通过检测以下多项中的至少两项是否同时成立，来判断预设的至少两种参数是否都达到了各自对应的参数阈值：
(1)判断冰箱的累积开门时间是否达到了第一时间阈值；
其中，第一时间阈值可以是任意可行的时间，例如，21.5分钟、30分钟、46.7分钟、51分钟等。
(2)判断压缩机2的累积运行时间是否达到了第二时间阈值；
其中，第二时间阈值可以是任意可行的时间，例如，1小时、3小时、4.6小时、5小时、12小时等。
(3)判断冰箱的储物室13的当前温度与预设温度之间的差值是否达到了温度阈值；
其中，温度阈值可以是任意可行的数值，例如，3.6℃、4℃、5℃、7.9℃、12℃等。
(4)判断蒸发器5的化霜次数是否达到了次数阈值。
其中，该次数阈值可以是任意可行的数值，例如2次、5次、9次等。
需要说明的是，上述的四项中任一项的起算节点都是上一次冷凝风机7降低转速并恢复转速时的时刻。
作为降低冷凝风机7转速的可选方式之一：
控制冷凝风机7降低到预设转速，并运行第一预设时间，该第一设定时间可以是任意可行的时间，例如30min、45min、1小时、1.5小时等。
该预设转速可以是不小于0的任意数值，例如，预设转速是冷凝风机7的额定转速的80％、75％、50％、45％、30％等；或者，预设转速比冷凝风机7的额定转速慢100r/min、150r/min、280r/min、300r/min等；或者，预设转速为0。
作为降低冷凝风机7转速的可选方式之：
控制所冷凝风机7在额定转速与预设转速之间交替运行，并运行第二预设时间，该第二设定时间可以是任意可行的时间，例如45min、56min、1小时、1.5小时等。
需要说明的是，在此过程中，额定转速与预设转速占用总时间的比例可以是任意可行的数值，例如1:1、1:3、2:3、5:4等。
本领域技术人员能够理解的是，当冷凝风机7的转速降低时，冷凝装置3的风冷效果将会变差，导致冷凝装置3具有较大的温升。由于冷凝装置3的一部分位于接水盘6内，使得高温的冷凝装置3能够通过该一部分加热接水盘6内的液体，促进液体的蒸发，防止了接水盘6内的液体过多，溢流到 冰箱周围的地面上的情形，提升了用户的使用体验。
进一步，为了满足用户对冰箱进行嵌装的需求，在本发明的一些实施例中，压机仓11还被设置为能够通过冰箱的底部进行散热。具体如下：
图3至图8是示出的是压机仓部分的结构。
如图3至图8所示，压缩机2、冷凝装置3和接水盘6从右至左依次布置在压机仓11内。并且压机仓11被分割为压机室111和蒸发室112，压缩机2位于压机室111内，接水盘6位于蒸发室112内。进一步，蒸发室111的底壁上设置有进风口1111，压机室112的底壁上设置有出风口1121。在冰箱正常使用的状态下，压机仓11的底壁与地面之间具有间隙(图中未标记)，以便使外界的空气从进风口1111进入压机仓11，对压缩机2和冷凝装置3冷却后再从出风口1121流出压机仓11。
如图5所示，机体1还包括设置在压机仓11底壁的底侧的挡风构件14，挡风构件14将压机仓11的底壁与地面之间的间隙分割成进风通道(图中未标记)和出风通道(图中未标记)；以使外界的空气从进风通道和进风口1111进入压机仓11，从出风口1121和出风通道流到冰箱周围的环境中。防止从出风口1121流出的热风再从进风口1111进入压机仓11，影响压机仓11的散热效果。
优选地，挡风构件14从后向前朝着靠近出风口1121的方向倾斜，以降低进风通道的风阻，从而使外界的空气更容易进入压机仓11，优化了压机仓11的风冷性能。
如图4至图8所示，进风口1111和出风口1121处安装有格栅，该格栅用于防止异物(例如，仓鼠、猫、鹦鹉等小动物)进入压机仓11。
如图7和图8所示，冷凝装置3包括冷凝器31和冷凝管32。冷凝管32的一端与压缩机2的出口连接；冷凝管32的另一端与冷凝器31的进口连接，以将压缩机2与冷凝器31流体连接到一起。冷凝管32的一部分位于接水盘6内，用于加热接水盘6内的冷凝水和/或化霜水，促进霜的融化，促进冷凝水的蒸发。进一步，冷凝管32的该一部分通过固定到接水盘6底壁和/或侧壁上的卡扣(图中未标记)固定。从压缩机2内流出的高温冷媒在流经冷凝管32的该一部分时，能够对通过该一部分将热量传递至接水盘6内的冷凝水和/或化霜水，从而促进霜的融化，以及促进冷凝水的蒸发。
此外，在本发明的其他实施例中，本领域技术人员也可以根据需要，将 冷凝管32的该一部分替换成其他高度较小的结构或构件。例如将冷凝管32的该一部分设置为串联在压缩机2与冷凝器31之间或者串联在冷凝器31与冷媒降压构件4之间的微通道散热器。
如图5、图7、图8和图9所示，冰箱还包括风筒8，风筒8内形成有风腔81，风筒8的外周壁与压机仓11的圆周壁抵接，以将压机仓11分割成压机室111和蒸发室112，以及使压机仓11内的空气全部流经风腔81。本领域技术人员能够理解的是，考虑到加工成本和/或装配成本，风筒8的外周壁与压机仓11的圆周壁之间可以不是完全密封地抵接，保留微小的间隙，以使压机仓11内的大部分空气全部流经风腔81。
如图6和图7所示，冷凝器31设置在风腔81中并且与风筒8嵌合，换句话说，冷凝器31的外周壁与风筒8内周壁抵接，以使流经风腔81内的空气都能够贯穿冷凝器31上的风道孔，或者使大部分的空气贯穿冷凝器31上的风道孔使少部分的空气从冷凝器31的圆周壁的外侧吹拂而过。本领域技术人员能够理解的是，嵌合到一起的冷凝器31和风筒8，能够提升压机仓11内的空气对冷凝器31制冷的利用率。
进一步，冷凝风机7也设置在风腔81中，并且与风筒8和/或冷凝器31固定到一起。优选地，冷凝风机7位于冷凝器31靠近压缩机2的一侧。冷凝风机7正转时能够驱动外界的空气从进风口1111进入压机仓11，对压缩机2和冷凝器31冷却后再从出风口1121流出压机仓11。或者，本领域技术人员也可以根据需要，将冷凝风机7设置在冷凝器31远离压缩机2的一侧。
本领域技术人员能够理解的是，彼此固定到一起的风筒8、冷凝器31和冷凝风机7，能够方便操作人员将该三者安装到压机仓11内以及将该三者从压机仓11内拆卸下来。
在本发明的该一些实施例中，冷凝器31是微通道冷凝器。此外，本领域技术人员也可以根据需要，将冷凝器31设置成其他任意可行的冷凝器，例如管式冷凝器。
进一步，在能够保证压机仓11内的空气全部或者大部分流经/吹拂冷凝器31的前提下，在本发明的其他实施例中，本领域技术人员也可以根据需要，省去风筒8的设置，并使冷凝器31的圆周与压机仓11的内周壁相匹配，以使冷凝器31的圆周壁与压机仓11的内周壁抵接，并因此将压机仓11分割成压机室111和蒸发室112。
可选地，冷凝风机7被配置为能够反向转动。反向转动的冷凝风机7使空气从出风口1121进入压机仓11，并从进风口1111流出压机仓11。在此过程中，气流反向吹拂冷凝器31，将冷凝器31表面上的灰尘朝着远离压缩机2的方向吹落。从冷凝器31上吹落的灰尘中，一部分会通过接水盘6的敞口落入接水盘6中并与冷凝水混合，避免了吹出压机仓11，污染冰箱周围的环境。
如图4和图8所示，进风口1111设置在接水盘6的一侧，优选地设置在接水盘6的正前方。
如图4所示，冰箱还包括设置在压机仓11内的导风结构9，该导风结构9配置成，将从进风口1111进入所述压机仓11内的空气引导至所述接水盘6内。具体地，该导风结构9包括压机仓11靠近进风口1111的侧壁，该侧壁与接水盘6靠近进风口1111的侧壁相配合引导从进风口1111进入压机仓11的空气吹向接水盘6。其中，压机仓11靠近进风口1111的侧壁为倾斜结构，具体地，该侧壁自底端至顶端，逐渐向后倾斜。
此外，在本发明的其他实施例中，本领域技术人员也可以根据需要，将导风结构9设置成其他任意可行的结构，例如设置在压机仓11内的导风板，该导风板的底端设置在进风口1111的前侧，该导风板的顶端延伸至接水盘6的正上方或内部。优选地，该导风板为弧形板，以减小风阻。
基于前文的描述，本领域技术人员能够理解的是，本发明通过将压缩机2和接水盘6分别设置在冷凝装置3的两侧，使得该三者在竖直方向上互补交叠，有效地降低了压机仓11的高度，进而在冰箱整机高度不变的情况下，使得储物室13的容积得到了有效地增加。
进一步，通过使进入压机仓11内的空气全部流经冷凝器31并吹拂冷凝器31，使得进入压机仓11内的空气得到了充分地利用，提升了冷凝器31的散热效果。
至此，已经结合前文的多个实施例描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围并不仅限于这些具体实施例。在不偏离本发明技术原理的前提下，本领域技术人员可以对上述各个实施例中的技术方案进行拆分和组合，也可以对相关技术特征作出等同的更改或替换，凡在本发明的技术构思和/或技术原理之内所做的任何更改、等同替换、改进等都将落入本发明的保护范围之内。
