Description

风道组件和冰箱
本申请要求于2017年2月15日提交中国专利局、申请号为201710080405.4、发明名称为“风道组件和冰箱”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
本发明涉及家用电器技术领域，具体而言，涉及一种风道组件和冰箱。
背景技术
对于冰箱等制冷产品，存在一个共性问题，冰箱内部温度存在不均匀的现象，而温度不均匀现象主要有两个主要原因：其一是热量损失；其二是送风口流量不均匀。
目前，冰箱内部的冷量是通过风道将流经蒸发器的冷空气输送到各个不同功能区，在这一过程中，所输送的冷量有两部分损失，一是流经风道的损失，另一部分是进入冰箱内部以后与壁面换热引起的热量损失。其中，送风口流量不均匀是由于风道结构设计不合理引起的。常见的问题是，分别位于左右侧的不同送风口之间，以及左侧总风量和右侧总风量之间存在流量不均匀的情况，导致冷空气所携带的冷量也不一致，从而造成冰箱箱体内部温度不均匀现象的产生。温度不均匀会对所保存的食物造成不利影响，减少食物的保存期限，从而严重损害用户的使用体验。由于收到体积和内部功能结构的限制，大多数风道都为非对称结构，这样也会导致流量分配不均匀，导致温度波动和温差产生，引起诸多问题。
缺点1：对于非对称的风道送风结构，各分支流道的送风风量不均匀，导致冰箱内部温差产生；
缺点2：对于非对称的风道送风结构，各分支流道的对称的送风口之间流量不均匀，导致冰箱内部温差产生；
缺点3：对于非对称的风道送风结构，不合理的送风风道设计会导致流动阻力增大，温度波动明显。
缺点4：对于非对称的风道送风结构，极易产生气动噪声。
发明内容
为了解决上述技术问题至少之一，本发明的第一方面的实施例提出了一种风道组件。
本发明的第二方面实施例，还提出了一种冰箱。
有鉴于此，根据本发明的第一方面的实施例，本发明提出了一种风道组件，包括：主体，主体上设置有进风口，并且进风口的位置偏向于主体的一侧；多个出风口，设置于主体两侧的区域；均风隔板，设置在主体上且位于进风口的上方；其中，均风隔板将通过进风口进入的空气分流至主体两侧的区域并经多个出风口排出。
本发明提供的风道组件，通过在进风口上方设置均风隔板，使位于主体一侧的进风口的进风能够在均风隔板的作用下均匀分流至风道组件的两侧并经出风口排出。对于非对称结构的风道，通过设置均风隔板将进风均匀导流至两侧的出风口，一般地，出风口与冰箱的内胆(制冷舱室)相通，使得制冷舱室两侧的进风口风量分配均匀，减少了不同部位之间的温差，减少了温度波动的发生，有效降低了流动阻力损失和气动噪声，在同等风扇转速下获得更大的流量。其中，均风隔板的顶端可为多段圆弧倒角结构，用于进一步减小气动阻力。
另外，本发明提供的上述实施例中的风道组件还可以具有如下附加技术特征：

在该技术方案中，第三出风口包括距离进风口较远一侧侧面的上部、中部和下部的三个出风口，通过设置上中下三个出风口，使得各个出风口出风的流量更加均匀，避免局部的温差与温度波动；而对于与出风口相连 通的制冷舱室能够获得更均匀的制冷效果，使制冷舱室内部各个位置的空气温度基本保持一致，抑制温度波动，避免局部温差。
在上述任一技术方案中，优选地，第三上部出风口的底部设置有第一导风斜面，第一导风斜面与水平面之间的夹角的范围为20°至45°。

在上述任一技术方案中，优选地，第一上部出风口与第一中部出风口之间距离的范围为50mm至150mm；第一下部出风口与第一中部出风口之间距离的范围为50mm至150mm。
在该技术方案中，通过设置第一上部出风口、第一中部出风口以及第一下部出风口之间的位置关系，使得经过风道组件的气流能够顺利地分别从对应位置的出风口流出，提升气体流动的效率，减小压力损失。在上述任一技术方案中，优选地，导流板的厚度的范围为5mm至12mm。
在该技术方案中，设置合适厚度的导流板既能够很好地实现对于气流的导流，使各个出风口的流量更加均匀，同时也不会因过厚的厚度增大气流的阻力，影响气体流动。一般地，导流板的厚度可选用5mm至12mm，还可依据风道的实际结构和气流调整导流板厚度。

在本发明的一个实施例中，优选地，均风隔板30的厚度的范围为5mm至12mm；或均风隔板30的厚度与进风口102截面宽度的比值的范围为5％至15％。
在该实施例中，设置合适厚度的均风隔板30既能够很好地实现对于气流的导流，使各个出风口20的流量更加均匀，同时也不会因过厚的厚度增大气流的阻力，影响气体流动。一般地，均风隔板30的厚度可选用5mm至12mm或进风口102截面宽度的5％至15％，这样既能够实现对于进风口102处进风的导流，同时不会对气流产生比较大的阻力，实际应用时还可依据风道的实际结构和气流调整均风隔板30的厚度。
本发明还提供了一种冰箱5，如图7和图8所示，本发明提供了一种冰箱5，包括：第一方面实施例的风道组件。
本发明提供的冰箱5，通过采用本发明第一方面实施例的风道组件，一般地，出风口20与冰箱5的内胆(制冷舱室)相通，使得制冷舱室两侧及顶部的进风口102风量分配均匀，减少了不同部位之间的温差，减少了温度波动的发生，有效降低了流动阻力损失和气动噪声，在同等风扇转速下获得更大的流量和制冷量，提高冰箱5的工作效率，节约能源。
图7所示的冰箱5包括前盖板总成52、后盖板总成54、风机总成56以及压缩机仓58(仓内设置有压缩机)，由上述几个部件以及本发明第一方面实施例的风道组件等部件构成冰箱5的制冷系统。通过设置本发明的风道组件使得制冷系统冷却的空气能够更均匀地流向冰箱5的制冷舱室，提升冰箱5的制冷效果及用户体验。
图8所示冰箱5的冰箱5门上设置有控制显示屏幕60，用户可以通过该控制显示屏幕60设定冰箱5的预设制冷温度，而通过设置本发明第一方 面实施例的风道组件，提升了冰箱5的制冷效率，使得制冷舱室能够更快地达到预设的温度，节约冰箱5的能耗。
另外，例如冰柜、空调等其他制冷设备也可采用本发明中所提供的风道组件，使得其出风量更加均匀，避免因风道结构的不对称性导致出风量不均、温度波动，以及结构对于气体的阻力浪费能耗。
在本发明的一个实施例中，优选地，如图7所示，还包括：风机总成56，所述风机总成56与所述风道组件相连接。
在该实施例中，由风机总成56流出的低温气体经过风道组件均匀地流向各个出风口，降低压力损失和气动噪声，并使得在风机总成56一定的送风量的条件下实现更好的制冷效果。
在本发明的一个实施例中，优选地，还包括：制冷舱室，制冷舱室与多个出风口相连接。
在该实施例中，经多个出风口流出的低温气体流入制冷舱室内，通过采用上述的风道组件，使得制冷舱室内的进风更加均匀，保证对于舱室内的均匀制冷，避免因气流不均导致的局部温度过高，影响食物的储存。
在本发明中，术语“多个”则指两个或两个以上，除非另有明确的限定。术语“安装”、“相连”、“连接”、“固定”等术语均应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或一体地连接；“相连”可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本说明书的描述中，术语“一个实施例”、“一些实施例”、“具体实施例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或实例。而且，描述的具体特征、结构、材料或特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精 神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
