Description

冰箱
本申请要求了申请日为2014年11月27日，申请号为201410696436.9，发明名称为“冰箱”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及一种冰箱，尤其涉及一种风冷冰箱。
背景技术
随着经济的发展，人们生活水平的逐渐提高，冰箱已经成为日常生活必须品进入千家万户。传统直冷冰箱的冷冻室直接由蒸发器围成或者冷冻室内设置有蒸发器。制冷时，冷冻室内的空气直接与蒸发器进行热交换。随着使用时间的增长，冰箱冷冻室内壁上或者设置在冷冻室内的蒸发器上会形成一层霜，霜层会影响蒸发器的制冷效果。因此，传统的直冷冰箱使用一段时间后需要人工除霜。而风冷冰箱则不会在冰箱冷冻室的内壁上形成霜层，因此风冷冰箱受到人们的欢迎。
图1所示为现有风冷冰箱的剖视图，所述风冷冰箱包括箱体1、设置在所述箱体1内的储藏室2、设置在所述箱体1内的风道3、设置在所述风道3内的蒸发器4以及设置在所述风道3内的风扇5。所述风道3包括进风口6和出风口7，所述进风口6、出风口7与所述储藏室2相连通，所述进风口6位于所述储藏室2的底部，所述出风口7位于所述储藏室2的顶部。所述储藏室2内的空气在所述风扇5的作用下从所述进风口6进入所述风道3，并经所述蒸发器4冷却后自所述出风口7流出至所述储藏室2内，从而实现位于所述储藏室2内的物品的冷却或冷藏。但是，当空气流经蒸发器4时，有很大一部分空气实际上会从所述蒸发器4与所述风道3内壁之间的空隙流过，从而使得空气的冷却效果变差，进而降低了所述储藏室的冷冻或冷藏效果。
鉴于上述问题，有必要对现有冰箱作进一步改进，以解决上述问题。
发明内容
本发明的目的在于提供一种冰箱，该冰箱设置有导流装置，从而使得空气全部经过蒸发器，进而提高了蒸发器的使用效率，提高了储藏室的冷冻或冷藏效果。

作为本发明的进一步改进，所述导流装置具有若干导流板，所述导流板包括第一导流板和第二导流板，所述第一导流板和所述第二导流板之间形成钝角。
作为本发明的进一步改进，所述风扇位于所述蒸发器与所述出风口之间。
作为本发明的进一步改进，所述风扇位于所述蒸发器与所述进风口之间。
作为本发明的进一步改进，所述风道具有主通道以及分别位于所述主通道两侧的进风通道和出风通道，所述蒸发器安装在所述主通道内，所述进风口位于所述进风通道与所述储藏室内壁相交处，所述出风口位于所述出风通道与所述储藏室内壁相交处。
作为本发明的进一步改进，所述进风通道的直径自所述进风口向所述进风通道与所述主通道的交界处逐渐变大。
作为本发明的进一步改进，所述储藏室包括第一储藏室以及与所述第一储藏室相连通并且位于所述第一储藏室下方的第二储藏室，所述第一储藏室的截面呈矩形，所述第二储藏室的截面呈直角梯形。
作为本发明的进一步改进，所述进风口和所述出风口均位于所述第二储藏室的内壁上。
作为本发明的进一步改进，所述导流装置固定安装在所述风道的内壁上。
作为本发明的进一步改进，所述导流装置固定安装在所述蒸发器上。
与现有技术相比，本发明的优势在于：本发明的冰箱通过设置有导流装置，从而不仅使得空气流经所述蒸发器时不会自所述蒸发器与所述风道之间形成的间隙流过，同时还可使得蒸发器的每个地方都有空气经过将产生的冷量带走，有效提高了所述蒸发器的利用率，增强了所述冰箱的冷冻或者冷藏效果。
附图说明

图2所示为本发明冰箱的剖视图。
图3所示为图2的局部放大图。
具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本发明进行详细描述。
在此，还需要说明的是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与本发明的方案密切相关的结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
另外，还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。
请参阅图2所示，本发明的冰箱100包括箱体10、设置在所述箱体10内的储藏室20、设置在所述箱体10内并与所述储藏室20相连通的风道30、设置在所述风道30内的蒸发器40和风扇50、设置在所述风道30内的导流装置60以及设置在所述箱体10内的压缩机仓70。
所述储藏室20包括第一储藏室21以及与所述第一储藏室21相连通并且位于所述第一 储藏室21下方的第二储藏室22。所述第一储藏室21的截面呈矩形，所述第二储藏室22的截面大致呈直角梯形。
所述风道30包括主通道31以及分别位于所述主通道31两侧的进风通道32和出风通道33。所述蒸发器40安装在所述主通道31内。所述进风通道32具有进风口321，所述进风口321位于所述第二储藏室22的侧壁上以使得所述进风通道32与所述第二储藏室22相连通。所述进风通道32的直径自所述进风口321向所述进风通道32与所述主通道31的交界处逐渐变大。所述出风通道33具有位于所述第一储藏室21侧壁上的出风口331和位于所述第二储藏室22侧壁上的出风口332，以使得所述出风通道33分别与所述第一储藏室21和第二储藏室22相连通。在本实施例中，所述出风口331、332的数量为两个，但是在其它实施例中，所述出风口331、332的数量可以依据需求而设。
本实施方式中，所述储藏室20分为第一储藏室21和第二储藏室22，所述出风口331、332对应设置有两个，分别对应所述第一储藏室21和第二储藏室22，以使得所述出风通道33分别与所述第一储藏室21和第二储藏室22相连通；当然，图2所示的所述储藏室20也可只是第二储藏室22，所述第一储藏室位于所述第二储藏室22的上方且未在图2中显示出来，此时两个所述出风口331、332则全部对应第二储藏室22，以使得所述出风通道33与所述第二储藏室22相连通并在第二储藏室22内形成冷气循环。
所述风扇50倾斜安装在所述风道30内，并且位于所述出风口331、332与所述蒸发器40之间，以便将经过所述蒸发器40冷却的空气吹进所述储藏室20内，从而实现储藏在所述储藏室20内的物品的冷冻或者冷藏。所述风扇50的出风方向与水平方向之间形成有夹角，所述夹角为锐角。虽然在本实施例中，所述风扇50位于所述出风口331、332与所述蒸发器40之间，但是在其他实施方式中，所述风扇50亦可设置成位于所述蒸发器40与所述进风口321之间。
请参阅图3并结合图2所示，所述导流装置60安装在所述风道30内，并且位于所述蒸发器40与所述进风口321之间。所述导流装置60包括若干导流板61。所述导流板61包括第一导流板611以及第二导流板612，所述第一导流板611与所述第二导流板612之间形成钝角。当空气流经所述导流装置60时，所述空气将会在所述导流装置60的引导下全部流经所述蒸发器40，而不会自所述蒸发器40与所述主通道31之间形成的间隙41流过，从而有效提高了所述蒸发器40的利用率，增强了所述冰箱100的冷冻或冷藏效果。虽然在本实施例中，所述导流板61的数量为三个，但是在其他实施例中，所述导流板61的数量可以依据需求而设。在本实施例中，所述导流装置60固定安装在所述风道30的内壁上，但是在其他实施方式中，所述导流装置60亦可固定安装在所述蒸发器40上。虽然在本实施例中，所述导流板61是由所述第一导流板611和所述第二导流板612组成且所述第一导流板611与第二导流板612之间形成钝角，但是在其他实施例中，所述导流板61亦可以为一体成型设置且其截面呈圆弧形，或者所述导流板61为一体成型的直板状。
请参阅图2所示，所述压缩机仓70用来收容压缩机(未图示)。所述压缩机仓70、进风通道32以及第二储藏室22大致位于同一直线上，且所进风通道32位于所述压缩机仓70与所述第二储藏室22之间。
当使用本发明的冰箱100时，位于所述储藏室20内的空气在所述风扇50的作用下自所述进风口321进入所述进风通道32；然后，空气在所述导流装置60的引导下流经所述蒸发器40的每个地方；接着，经过所述蒸发器40冷却的空气再经过所述出风通道33和出风口331、332流入所述储藏室20，从而实现储藏在所述储藏室20内的物品的冷冻或冷藏。
相较于现有技术，本发明的冰箱100通过设置有导流装置60，从而不仅使得空气流经所述蒸发器40时不会自所述蒸发器40与所述风道30之间形成的间隙41经过，同时还可使得蒸发器40的每个地方都有空气经过将产生的冷量带走，有效提高了所述蒸发器40的利用率，增强了所述冰箱100的冷冻或者冷藏效果。
以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围。
