送风装置及具有该送风装置的冰箱
本申请要求了申请日为2017年04月14日，申请号为201710245864.3，发明名称为“送风装置及具有该送风装置的冰箱”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
本发明涉及冷藏冷冻储物领域，特别是涉及一种送风装置及具有该送风装置的冰箱。
背景技术
近年来，随着人们生活水平的提高以及环境意识的增强，对冰箱的要求从满足低温制冷向食物的保鲜性能转移了。所以风冷冰箱逐步受到人们的青睐。对于风冷冰箱，食物的保鲜性能在很大的程度上取决于风冷冰箱储藏室内气流循环及箱内各个部分之间的温差。箱内气流循环合理，温差越小，则冰箱的保鲜性能越好。而决定冰箱的气流循环是否合理的关键部件就是风道，它控制了冰箱的风向及流量大小，直接决定了冰箱的制冷保鲜效果。为优化存储空间，单个储物间室一般会被搁物架或者抽屉等搁物装置分隔为多个细化的储物空间，根据存放物品的多少，每一个储物空间所需要的冷量也是不同的，因此，冷风不加控制地直接从储物间室的某处直接进入储物间室内，会造成部分储物空间过 冷，部分储物空间冷量不足的问题。
而且，在目前市面上的风冷冰箱风路设计中，大部分风冷冰箱是将蒸发器设置于一个单独的容纳室内，利用复杂的风道***将蒸发器的容纳室连通于各储物间室，并利用风机将通过蒸发器的产生的冷风输送至各储物间室。风道内设置控制装置(如电动风门)对进入各储物间室的风道的开启和关闭，或者调节进入各储物间室内的风量。但是这种结构较为复杂，不便于统一控制。并且无法根据各储物空间的冷量需求对进入各储物间室内的冷风进行分配和调控。

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。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是根据本发明一个实施例的送风装置的示意性结构图；
图2是图1所示的送风装置的示意性分解图；
图3是图1所示的送风装置的另一视角的示意性分解图。
具体实施方式
图1是根据本发明一个实施例的送风装置的示意性结构图；图2是图1所示的送风装置的示意性分解图；图3是图1所示的送风装置的另一视角的示意性分解图。如图1至图3所示，本发明实施例提供了一种用于冰箱的送风装置。该送风装置可包括壳体20、调节件30和风机50。壳体20可具有优先呈筒状的周壁部21，以及设置于周壁部21的一端的第一轴向端部22。第一轴向端部22上设置有多个出风通道25。每个出风通道25具有出风口和位于第一轴向端部内侧的进口，以使进入壳体20的气流从多个出风通道25中的一个或多个流出壳体20。调节件30可转动地设置于壳体20内，且具有一个或多个遮挡板部31，以在转动到不同的转动位置处，使一个或多个遮挡板部31对每个出风通道25的进口进行完全遮蔽、部分遮蔽或完全暴露，从而调整多个出风通道25的进口各自的进风面积，以调节经由每个出风通道25流出的出风风量。风机50安装于壳体20内，可配置成促使气流进入壳体20，且促使进入壳体20的气流经由被部分遮蔽或完全暴露的进口流出壳体20。也就是说，当某个出风通道25的进口被部分遮蔽或完全暴露时，风机50可促使气流进入该出风通道25，然后流出壳体20。
本发明实施例中的送风装置的调节件30能够将流入壳体20的冷风可控地分配至多个出风通道25的进口，可以实现控制与每个出风通道25连通的冰箱送风风道/冷风出口的开闭和/或对每个 冰箱送风风道/冷风出口的出风风量进行调节，进而来满足不同储物间室的冷量需求，或者一个储物间室的不同的位置处的冷量需求，或者一个储物间室内不同的储物空间的冷量需求。该风机50可使本发明实施例中的送风装置独立进风，位于壳体20内，可使送风装置的结构紧凑、体积小。该风机50也可使本发明实施例中的送风装置对流出冷却室的气流进一步提速。也就是说，该送风装置可适用于冷却室出口处设置风机的冰箱，也适用于冷却室出口处未设风机的冰箱。
在本发明的一些实施例中，壳体20还可包括第二轴向端部23，第二轴向端部23可设置于周壁部21的另一端。且第二轴向端部23上可设置有一个或多个进风口，在一些替代性实施例中，进风口也可设置于周壁部21。
进一步地，周壁部21可与第一轴向端部22和第二轴向端部23中的一个一体成型，另一个可卡接于周壁部21。例如，第二轴向端部23与周壁部21一体成型。第一轴向端部22与周壁部21卡接。具体地，从第一轴向端部22的边缘处向第二轴向端部23延伸出多个卡柱24，每个卡柱24上开设有卡孔；周壁上具有多个沿周壁部21的轴向方向延伸的卡槽，卡槽内设置有与一个卡柱24上的卡孔配合的卡扣，以进行卡接。
在本发明的一些实施例中，每个出风通道25的出风口配置成经由其流出的气流至少具有沿第一轴向端部22的径向方向流动的速度分量。例如，可使流出每个出风口的气流沿第一轴向端部22 的径向方向流动；或可使流出每个出风口的气流具有沿第一轴向端部22的径向方向流动的径向速度分量和沿第一轴向端部22的轴向方向流动的轴向速度分量，径向速度分量大于轴向速度分量。在本发明的一些实施例中，每个出风通道25的出风口朝向第一轴向端部的径向外侧。进一步地，在朝向径向外侧时也可同时向第一轴向端部22的轴向方向倾斜，倾斜角度可为0°至30°，例如5°、8°等。
在本发明的一些实施例中，每个出风通道25可具有从该出风通道25的出风口的远离第一轴向端部22内侧的口边缘段处向第一轴向端部22的中央延伸的第一成型面，第一成型面与第一轴向端部的轴线之间的夹角为60°至90°，例如可为75°、80°、85°等。
在本发明的一些进一步的实施例中，每个出风通道25还具有从该出风通道的出风口的靠近第一轴向端部内侧的口边缘段处向第一轴向端部的中央延伸的第二成型面，第二成型面与第一轴向端部的轴线之间的夹角为60°至90°，例如可为78°、85°、88°等。
在本发明的一些进一步的实施例中，每个出风通道25还具有两个分别从该出风通道的出风口的两个沿平行于第一轴向端部的轴线方向延伸的口边缘段处向第一轴向端部的中央延伸的第三成型面，两个第三成型面之间的距离沿着气流的流动方向逐渐变大。
在本发明的一些进一步的实施例中，每个出风通道25还具有 两个分别从第一成型面的内端和第二成型面的内端沿第一轴向端部的轴线方向延伸至该出风通道25的进口的口边缘处的两个第四成型面。
在本发明的一些进一步的实施例中，每个出风通道25的进口优选为扇形，也就是说，每个出风通道25的进口的口边缘包括：同轴设置的弧形内边缘段和弧形外边缘段，以及连接弧形内边缘段和弧形外边缘段的两个直线边缘段；且弧形内边缘段与第一轴向端部22同轴设置。
在本发明的一些替代性实施例中，每个出风通道25还可具有其它类型的通道形式，例如具有圆管部等。在本发明的一些替代性实施例中，每个出风通道25也可为轴向出风通道或周向出风通道。
在本发明的的一些优选的实施例中，风机50可配置成促使气流沿周壁部21的轴向方向流动。例如，风机50可为轴流风机。轴流风机也可被称为轴流风扇、轴流式风机、轴流式风扇。采用轴流风机可显著降低风阻，保证送风顺畅，提高送风效率。
在本发明的一些实施例中，调节件30可包括遮挡转板。遮挡转板具有一个或多个遮挡板部31，以及至少一个流通部32。每个流通部32为一个或多个贯穿遮挡转板的流通孔，以使气流经由至少一个流通部32进入被部分遮蔽或完全暴露的出风通道25的进口。例如，在一些实施例中，多个出风通道25的进口沿第一轴向端部22的周向方向依次设置。则遮挡板部31和流通部32沿第一 轴向端部22的周向方向依次设置。进一步地，每个流通部32可包括一个流通孔，遮挡转板的每相邻两个流通孔之间的部分为一个遮挡板部31。
在本发明的一些实施例中，为了便于送风装置的转动，第一轴向端部22的内表面具有环形凹槽28。遮挡转板的朝向第一轴向端部22的一侧表面上具有***环形凹槽28的环形凸起34。环形凸起34和换向凹槽相配合的设置可便于遮挡转板的快速安装，而且，可引导遮挡转板更顺畅的进行转动。进一步地，调节件30还包括从遮挡转板的周缘处向远离第一轴向端部22的方向延伸出的筒状壁33。筒状壁33不仅可保证调节件30的运动更加平稳，而且，可引导进入壳体20内的气流流动，使气流更好地流经流通部32。
在本发明的一些实施例中，送风装置还可包括电机41和传动机构。电机41可设置于周壁部21的外侧。例如壳体20还包括设置于周壁部21外侧的电机容纳部29，电机41设置于电机容纳部29内。传动机构配置成将电机41输出的旋转运动传递至遮挡转板。例如，传动机构可包括齿轮42和齿圈43。齿轮42安装于电机41的输出轴。齿圈43设置于遮挡转板或与遮挡转板一体成型，齿圈43与齿轮42啮合，以将电机41输出的旋转运动传递至遮挡转板。优选地，环形凸起34的外周面上形成有齿圈43。
本发明实施例的送风装置通过传动机构将电机41输出的旋转运动减速地传递至调节件30，可弱化电机41输出轴的晃动对调节 件30转动的影响，可使调节件30的转位准确，能使调节件30正确地转动到预定的位置处，保证对每个出风通道25的进口进行精确遮蔽或暴露。此外，传动机构也可具有减速增扭的作用，可消除电机41转动时的卡顿现象。电机41设置的特殊位置可使送风装置的整体厚度减薄，节省空间，以特别使用于冰箱。
在本发明的一些实施例中，送风装置还可包括风机，优选地设置于壳体20内，配置成促使气流进入壳体20，且促使进入壳体20的气流经由被部分遮蔽或完全暴露的出风通道25的进口流出壳体20。优选地，风机为轴流式风机或轴流式叶轮，即该风机是从其轴向方向的一侧吸入气流，并向其轴向方向的另一侧吹出气流。
在本发明的一些实施例中，出风通道25的数量为多个，多个出风通道25的进口沿第一轴向端部22的周向方向依次设置，可选为均匀地依次设置。当然，多个出风通道25的进口也沿第一轴向端部22的周向方向也可为不均匀地设置。当多个出风通道25的进口不均匀地设置时，每两个相邻的出风通道25的进口之间的距离可相等，两端的两个出风通道25的进口为不相邻的两个出风通道25的进口。
在本发明的一些实具体地施例中，如图1至图3所示，出风通道25的数量可为三个，三个出风通道25的进口沿第一轴向端部22的周向方向且可沿顺时针方向(以观察者从第二轴向端部23看向第一轴向端部22的视线为基准)依次间隔设置。且，处于中间的出风通道25的进口251与另外两个出风通道25的进口之间 的距离均可为一个出风通道25的进口的长度。遮挡板部31和流通部32的数量均为三个。三个遮挡板部31分别为第一遮挡板部311、第二遮挡板部312和第三遮挡板部313。三个流通部32分别为第一流通部、第二流通部和第三流通部。遮挡板部31和流通部32沿第一轴向端部22的周向方向且可沿顺时针方向依次间隔设置。第一遮挡板部311和第二遮挡板部312均配置成允许其完全遮蔽一个大小的出风通道25的进口的区域。第三遮挡板部313配置成允许其至少完全遮蔽两个大小的出风通道25的进口的区域，如第三遮挡板部313可遮蔽两个大小的出风通道25的进口的区域。第一遮挡板部311和第二遮挡板部312之间的流通部32为第一流通部，配置成完全暴露一个大小的出风通道25的进口的区域。第二遮挡板部312和第三遮挡板部313之间的流通部32为第二流通部，配置成完全暴露一个大小的出风通道25的进口的区域。第三遮挡板部313和第一遮挡板部311之间的流通部32为第三流通部，配置成至少可完全暴露两个大小的出风通道25的进口的区域，例如可完全暴露两个大小的出风通道25的进口的区域。
在工作时，调节件30转动可使不同的出风通道25的进口处于打开状态，例如当第一遮挡板部311遮挡处于中间的出风通道25的进口251时，另外两个出风通道25的进口中处于中间出风通道25的进口251的逆时针方向的出风通道25的进口252可处于打开状态，处于中间出风通道25的进口251的顺时针方向的出风通道25的进口253可被第二遮挡板部312遮盖。再例如，当第二 遮挡板部312遮挡处于中间出风通道25的进口251的逆时针方向的出风通道25的进口252时，处于中间出风通道25的进口251的顺时针方向的出风通道25的进口253可被处于导通状态，中间出风通道25的进口251可被第三遮挡板部313遮盖。在本发明的一些实施例中，也可仅使每个出风通道25的进口的部分被遮蔽。在本发明的一些实施例中，多个出风通道25的进口中任意两个出风通道25的进口的大小可相等也可不等，优选为相等。
本发明实施例还提供了一种冰箱，该冰箱为风冷冰箱，其可具有箱体。箱体内具有一个或多个储物间室，每个储物间室也可被搁物板/搁物架分隔成多个储物空间。且，箱体内设置有风道***和上述任一实施例中的送风装置。
在一些可选的实施例中，风道***可具有进风风道、多个冰箱送风风道。每个冰箱送风风道均具有一个或多个冷风出口。进风风道可与冰箱的冷却室连通，以接收经冷却室内的冷却器冷却后的气流。送风装置的进风口与进风风道连通。送风装置的多个出风通道25的出风口分别与多个冰箱送风风道连通，以使来自进风风道内的气流受控地/可分配地进入相应的冰箱送风风道内。
在一些优选的实施方式中，多个冰箱送风风道可配置成使流出风道***的气流分别从冰箱的一个储物间室的间室壁上的多个位置处进入该储物间室。例如，送风装置的出风通道25的进口可为3个，如第一出风通道25的进口、第二出风通道25的进口和第三出风通道25的进口。冰箱送风风道可为3个，如与第二出风 通道25的进口连通的第一风道、与第一出风通道25的进口连通的第二风道、与第三出风通道25的进口连通的第三风道。第二风道可具有两个或四个冷风出口，对称设置在该储物间室后壁上部。第一风道位于第二风道的一侧，具有一个冷风出口，设置在该储物间室后壁的中部。进一步地，第一风道的上端可具有桥接风道，以将第一风道中的冷风导向到第二风道的另一侧。第三风道可位于第二风道的另一侧，具有一个冷风出口，设置在储物间室后壁的下部部。进一步地，第三风道的上端具有桥接风道，以将第三风道中的冷风导向到第二风道的另一侧。进一步地，也可使用两个搁物架将该储物间室分割为三个储物空间，每个冰箱送风风道与一个储物空间连通。
在本发明的一些替代性实施方式中，每个出风通道25的进口分别可与一个储物间室连通。在本发明的另一些替代性实施方式中，每个出风通道25的进口的部分可与一个储物间室连通，其余部分可与另一个储物间室连通。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
