冰箱 技术领域
本发明属于制冷设备技术领域，具体提供了一种冰箱。
背景技术
现有风冷式冰箱通常包括储藏室和制冷室，储藏室和制冷室还通过通道彼此连通，以使空气在储藏室和制冷室之间循环。其中，储藏室用于储存食材、药品等需要被冷藏的物品，制冷室内布置有蒸发器，以通过该蒸发器冷却流向储藏室的气流。
现有的制冷室通常被布置在储藏室的正后方，导致储藏室的纵深被减小，降低了储藏室的纵向使用空间，影响用户的使用体验。
发明内容
为了解决现有技术中的上述问题，本发明的一个目的在于，提供一种新的冰箱，以将制冷室设置在储藏室的下方，从而提升储藏室在纵深方向(冰箱前后方向)上对冰箱的空间使用率，以提升储藏室的纵向使用空间。
本发明进一步的目的在于，在储藏室的下方设置至少两个制冷室，并在每一个制冷室内设置相应的蒸发器，以使至少两个制冷室同时对储藏室制冷，尤其是对不同的储藏室或者储藏格进行分别制冷。
为实现上述目的，本发明提供了一种冰箱，包括：

进一步，通过使风机沿着靠近送风通道的方向倾斜向上设置，使得风机能够改变从制冷室排出的冷风的流动方向，以使气流尽可能地与送风通道平行，降低了空气流动的阻力。

图1和图2示出的是本发明一些实施例中冰箱的间室分布情况。
如图1和图2所示，在该一些实施例中，冰箱包括箱体1和蒸发器2。其中，箱体1具有位于其底部并且在水平方向并列的至少两个制冷室11，箱体1还具有位于该至少两个制冷室11上方的储藏室12。优选地，每一个制冷室11分别对应有一个储藏室12，每一个制冷室11和与其相对应的储藏室 12通过送风通道13连通。该送风通道13位于制冷室11和储藏室12的后侧。进一步，箱体1在制冷室11和储藏室12的前侧还设置有回风通道(图中未标记)，该回风通道用于将制冷室11和储藏室12连通，以使空气按照制冷室11、送风通道13、储藏室12和回风通道的顺序依次循环流动。
优选地，如图1和图2所示，布置在储藏室12下方的制冷室11的数量为两个，两个储藏室12在竖直方向上依次布置。其中，每一个制冷室11分别布置有一个蒸发器2。两个蒸发器2中的一个为冷冻蒸发器，两个蒸发器2中的另一个为冷藏蒸发器。或者，本领域技术人员也可以根据需要，将两个蒸发器2中的冷冻蒸发器或冷藏蒸发器替换为变温蒸发器。
进一步优选地，多个制冷室11和多个储藏室12中，彼此相邻的两个之间通过保温板隔开，以避免热量在该彼此相邻的两个之间传递，影响冰箱的制冷效果，或者储藏室12的储藏效果。
需要说明的是，冷冻蒸发器所对应的储藏室12为冷冻室，用于冷冻其内的被储藏物(例如食材、药品等)；冷藏蒸发器所对应的储藏室12为冷藏室，用于冷藏其内的被储藏物；变温蒸发器所对应的储藏室12为变温室，能够根据其内被储藏物的温度需求或者用户的需求调整储藏温度。
进一步，为了使储藏室12的空间得到有效地利用，将每一个储藏室12分割为多个储物格121，以使用户将被储藏物放置在不同的储物格121中。
此外，在本发明其他的一些实施例中，本领域技术人员也可以根据需要，将布置在储藏室12下方的制冷室11的数量设置为三个，以使三个制冷室11分别布置冷冻蒸发器、冷藏蒸发器和变温蒸发器。相应地，储藏室12的数量也被设置为三个。
需要说明的是，虽然前文是以两个和三个制冷室11来对本发明的冰箱进行说明，但这并不表示本发明所要保护的冰箱仅能具有两个或三个制冷室11，其还可以具有其它任意数量的制冷室11，例如4个、7个、8个等。
此外，在本发明其他的一些实施例中，本领域技术人员也可以根据需要，使多个制冷室11对应一个储藏室12，或者使一个制冷室11对应多个储藏室12。
继续参阅图1和图2，蒸发器2在竖直方向上的高度小于其在水平方向上的长度和宽度。换句话说，蒸发器2整体上呈长方体状，其被横置在制冷室11内，以降低冷藏室11的高度，从而在竖直方向上为储藏室12保留更 多的存储空间。
如图2所示，在本发明的该一些实施例中，冰箱还包括为每一个蒸发器2单独配置的风机3，风机3位于其对应的蒸发器2的后侧，并且风机2沿着远离其对应的蒸发器2的方向倾斜向上设置。换句话说，风机3位于蒸发器2与送风通道13之间。
虽然图中并未示出，但是在该一些实施例中，风机3为离心风机，其具有轴向进风口和径向出风口，该轴向进风口指向与该风机3相对应的蒸发器2。
进一步，送风通道13被设置为大体平行于竖直方向。基于此，本领域技术人员能够理解的是，风机3被设置为前述的形式，能够使风机3的高度与气流的风阻达到最优平衡。具体来说，相对于将风机3竖直放置，倾斜设置的风机3的高度得到了有效缩减；同时还使得风机3能够将沿水平方向流动的气流改变成沿竖直方向流动的气流，降低了气流的风阻。
为了进一步降低气流在制冷室11与出风通道13衔接处的风阻，本领域技术人员还可以根据需要，将制冷室11的顶壁位于蒸发器2后方的部分，沿着远离其对应的蒸发器2的方向倾斜向上设置。同时，制冷室11的顶壁倾斜向上的该部分，还能够在竖直方向上给风机3提供更充裕的安装空间。
继续参阅图2，在本发明的该一些实施例中，箱体1还具有压机仓14，压机仓14设置在前述至少两个制冷室11的后侧，即，压机仓14和前述至少两个制冷室11在水平方向上依次分布，以避免压机仓14和制冷室11在竖直方向上叠加时，影响储藏室12的容积。
继续参阅图2，在本发明的该一些实施例中，冰箱还包括设置在压机仓14内的接水盘4。并且箱体1上设置有排水管道15，排水管道15用于将至少两个制冷室11内的冷凝水和/或化霜水引导至接水盘4。具体地，每一个制冷室11分别对应一个排水管道15，并且每一个制冷室11的底壁上都设置有出水口，排水管道15的顶端与该出水口密封连接，排水口15的底端延伸至接水盘4内或者延伸至接水盘4的正上方。
图3至图5示出的是本发明一些实施例中的蒸发器的主要结构。
如图3至图5所示，在该一些实施例中，蒸发器2包括蒸发器本体21和盖板22，盖板22贴附在蒸发器本体21的顶侧，并且盖板22和蒸发器本体21围成有容霜空间23，容霜空间23具有开口231。
继续参阅图3至图5，盖板22面向蒸发器本体21的一侧形成具有开口的沉槽221，在盖板22与蒸发器本体21贴合到一起之后，该沉槽的顶壁、侧壁和蒸发器本体21的顶面共同围成容霜空间23，而沉槽221的开口则构成容霜空间23的开口231。从回风通道流动到制冷室11内的气流通过开口231进入容霜空间23，然后再穿过蒸发器本体21上的通风间隙，流动到出风通道13中。
优选地，容霜空间23的高度大于蒸发器本体21上凝霜的最大高度，以防止凝霜与容霜空间23的顶壁(盖板22)相抵时，阻碍空气流动。
如图5所示，在本发明的该一些实施例中，冰箱还包括化霜装置5，该化霜装置5用于加热蒸发器2，以融化蒸发器2上的凝霜。
作为示例一，该化霜装置5是缠绕在、贴合到或嵌合到蒸发器本体21上的电加热装置，电加热装置通电时对蒸发器本体21加热，以融化蒸发器本体21上的凝霜。
作为示例二，该化霜装置5是缠绕在、贴合到或嵌合到蒸发器本体21上并且允许冷媒流经的管路，该管路与冰箱的压缩机串联，以接收从压缩机流出的高温冷媒，从而通过该高温冷媒对蒸发器本体21进行加热，以融化蒸发器本体21上的凝霜。
本领域技术人员能够理解的是，在化霜装置5加热蒸发器本体21的过程中，风机3停止转动，此时，容霜空间23的侧壁会限制空气的流动，而容霜空间23内被加热的空气会促进容霜空间23内凝霜的融化，提升了化霜速率。
图6示出的是本发明另一些实施例中冰箱的间室分布情况。
与前述实施例不同的是，在该另一些实施例中，多个储藏室12中的至少部分储藏室12沿水平方向依次分布。
基于前文的描述，本领域技术人员能够理解的是，本发明的冰箱通过将制冷室布置在储藏室的底侧，相对于将制冷室布置在储藏室的后侧而言，不仅增加了储藏室的纵深，而且还适当地抬升了储藏室的高度，避免了用户在取物、放物时过度下蹲，使储藏室更加符合用户的取物、放物习惯。
进一步，通过使底置的多个制冷室在水平方向上依次布置，避免了多个制冷室在竖直方向上叠加时过度得抬升储藏室的底壁，降低储物室的储物能力。
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。
