分路送风装置及具有该分路送风装置的冰箱 技术领域
本发明涉及制冷装置，特别是涉及一种分路送风装置及具有该分路送风装置的冰箱。
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逐渐向食物的保鲜性能转移。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的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。
此外，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。
目前市面上的风冷冰箱风路设计中，一部分风冷冰箱是采用冷冻室出风，直接传递给冷藏室。一般的风冷冰箱的冷冻室和冷藏室之间没有风门，且风道上的各个风路都是串联的，当冷藏室温度达到设定的温度时，冷冻室的冷气还继续流向冷藏室，导致冷藏室的温度一直处于循环波动的状态，即冷藏室内的温度一直在变化，大大影响了冰箱的保鲜性能。还有一部分风冷冰箱是将蒸发器设置于一个单独的容纳室内，利用复杂的风道系统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)以控制与各储物间室连通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。
发明内容

可选地，该分路送风装置还包括：电机，设置在第一调节件和/或第二调节件的转盘部的径向外侧；和

可选地，壳体还包括：
一个或多个肋板，从基座的一个表面延伸出；

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：

具体实施方式
图1是根据本发明一个实施例的分路送风装置100的示意性结构图，图2是根据本发明一个实施例的分路送风装置100的示意性分解图。如图1和图2所示，本发明实施例提供了一种用于冰箱的分路送风装置100。该分路送风装置100可包括壳体20、第一调节件30和第二调节件30'。壳体20可具有关于一几何对称面对称的第一半部21和第二半部21'。第一半部21和第二半部21'均具有至少一个进风口211和多个出风口212，以使气流经由至少一个进风口211进入每个半部内，并从多个出风口212流出每个半部。
第一调节件30和第二调节件30'关于上述几何对称面对称布置，分别配 置成受控地对第一半部21和第二半部21'的每个出风口212进行完全遮蔽、部分遮蔽或完全暴露，以调整各个出风口212的出风面积。例如，第一调节件30和第二调节件30'可在不同的位置处对每个出风口212进行完全遮蔽、部分遮蔽或完全暴露。
本发明实施例中的分路送风装置100的第一调节件30和第二调节件30'能够将从进风口211流入的冷风可控地分配至多个出风口212，可以实现控制与每个出风口212连通的出风风道320(参见图11)的开闭和/或对每个出风风道320内的出风风量进行调节，进而来满足不同储物间室200(参见图10)的冷量需求，或者一个储物间室200不同的位置处的冷量需求，或者一个储物间室200内不同的储物空间的冷量需求。
特别地，由于第一半部21和第二半部21'对称设置，分别与第一半部21和第二半部21'连通的多个出风风道320也可关于冰箱储物间室200的纵向对称面对称设置，这样，在每次调节时，可使用于向冰箱储物间室200的每层区域送风的出风口212同时打开、关闭或部分遮蔽，从而使进入冰箱储物间室200每层区域的风量一致，使该储物间室200的每层空间以及该储物间室受冷均匀。具体地，第一调节件30和第二调节件30'可同步反向运动，以同步对称地对第一半部21和第二半部21'的多个出风口212进行完全遮蔽、部分遮蔽或完全暴露。
在本发明的一些实施例中，如图2所示，壳体20可包括基座22。第一半部21和第二半部21'均可包括从基座22的一个表面延伸出的圆弧形周壁，且第一半部21和第二半部21'的圆弧形周壁上分别形成有各自的多个出风口212。圆弧形周壁可是与基座22的表面呈预定角度延伸的，优选垂直于基座22的表面延伸。多个出风口212可沿每个圆弧形周壁的周向方向间隔地形成在圆弧形周壁上。在一些实施例中，每个圆弧形周壁可为一完整的圆弧形周壁段，其上开设有多个出风口212，每个出风口212均可具有口边缘。在另一些实施例中，圆弧形周壁可包括至少3个圆弧形周壁段部，以及位于两个圆弧形周壁段部之间的间隔。每两个圆弧形周壁段部之间的间隔就是一个出风口212。在加工时，可仅使每个圆弧形周壁段部从基座22的多个位置处向基座22的一侧延伸出。
在本发明的一些实施例中，第一半部21和第二半部21'的至少一个进风口211均为一个，且第一半部21和第二半部21'的圆弧形周壁的沿各自周向 方向的两端限定出各自的进风口211。在本发明的一些替代性实施例中，第一半部21和第二半部21'均还包括从基座22的一个表面延伸出的另一圆弧形周壁，其与圆弧形周壁构成筒状结构，且第一半部21和第二半部21'的另一圆弧形周壁上分别形成有各自的至少一个进风口211。
在本发明实施例中，第一调节件30和第二调节件30'均包括一个或多个沿各自的圆弧形周壁的周向方向间隔设置的遮挡部31，第一半部21和第二半部21'的每个遮挡部31的朝向各自的圆弧形周壁的表面的至少部分与圆弧形周壁同轴设置。而且，第一调节件30和第二调节件30'绕各自的圆弧形周壁的轴线可转动地安装于壳体20，以使各自的一个或多个遮挡部31在运动到不同的位置处时对各自的每个出风口212进行完全遮蔽、部分遮蔽或完全暴露。
具体地，每个遮挡部31可为弧形遮挡板，以对每个出风口212进行遮蔽或暴露。第一调节件30和第二调节件30'的每个遮挡部31分别位于各自的圆弧形周壁的径向内侧，也可分别位于各自的圆弧形周壁的径向外侧。例如，在第一调节件30和第二调节件30'的每个遮挡部31分别位于各自的圆弧形周壁的径向内侧的情况下，且在第一调节件30和第二调节件30'绕各自的圆弧形周壁的轴线转动时，在一些实施例中，弧形遮挡板的外侧表面可始终密封贴附在相应的圆弧形周壁的内侧表面，这样弧形遮挡板在不同的转动位置处能够受控地打开或关闭相应的一个或多个出风口212。在另一些实施例中，每个遮挡部与相应的圆弧形周壁之间的存在预定的间距，每个遮挡部的弧形外表面的沿其转动方向的两端均可安装一密封垫33，以便于遮挡部的转动，且至少部分地阻碍气流经每个遮挡部的外表面与相应的圆弧形周壁的内表面之间的间隙流向每个出风口212。
在本发明的一些实施例中，第一调节件30和第二调节件30'均还可包括转盘部32，第一半部21和第二半部21'的每个遮挡部31分别从各自的转盘部32的一个表面延伸出。转盘部32可圆盘状或环圈状，全周式结构可使第一调节件30和第二调节件30'的运动更加平稳。具体地，在一些实施例中，第一调节件30和第二调节件30'的转盘部32可转动地安装于各自的圆弧形周壁的远离基座22的一端端面。每个遮挡部31安装于相应的圆弧形周壁的径向内侧，该遮挡部31的远离相应的转盘部32的一端端面可与基座22接触抵靠。
在本发明的一些实施例中，分路送风装置100还可包括电机40和传动机构50。电机40设置在第一调节件30和/或第二调节件30'的转盘部32的径向外侧。传动机构50可配置成将电机40输出的旋转运动减速地传递至第一调节件30和第二调节件30'。发明人在设计的过程中，发现第一调节件30和第二调节件30'的转动不够平稳，原因在于电机40的晃动，因此发明人提出了使用传动机构50来弱化电机40输出轴的晃动影响，以使第一调节件30和第二调节件30'的转位精确。传动机构50的减速增扭功能也可消除电机40的卡顿现象。电机40设置的特殊位置(即在第一调节件30和/或第二调节件30'的转盘部32的径向外侧)可使分路送风装置100的整体厚度减薄，节省空间，以特别使用于冰箱。
传动机构50优选为齿轮传动机构。具体地，传动机构50可包括第一齿轮51和两个相互啮合的第二齿轮52。第一齿轮51安装于电机40的输出轴。两个相互啮合的第二齿轮52，分别与第一调节件30和第二调节件30'的转盘部32同轴地固定于第一调节件30和第二调节件30'的转盘部32的另一表面。而且一个第二齿轮52与第一齿轮51啮合。采用两个相互啮合的第二齿轮52能够很好的实现第一调节件30和第二调节件30'的同步反向运动，从而保证调节的准确性。
进一步地，在第一调节件30和第二调节件30'的转盘部32可转动地安装于各自的圆弧形周壁的远离基座22的一端端面，且转盘部32呈环圈状时，两个第二齿轮52可起到密封每个圆弧形周壁的远离基座22的一端的端部开口的作用。当然，转盘部32呈圆形板状时，用于密封每个圆弧形周壁的远离基座22的一端的端部开口。
具体地，在本发明的一些实施例中，第一半部21和第二半部21'上的出风口212的数量均为三个，分别为第一出风口213、第二出风口214和第三出风口215，沿各自的周向方向依次间隔设置。第一半部21的第一出风口213、第二出风口214和第三出风口215可沿其周向方向且沿逆时针方向依次间隔设置；第二半部21'的第一出风口213、第二出风口214和第三出风口215可沿其周向方向且沿顺时针方向依次间隔设置。第一调节件30和第二调节件30'的遮挡部31的数量均为两个，分别为第一遮挡部311和第二遮挡部312。第一调节件30的第一遮挡部311和第二遮挡部312可沿顺时针方向依次间隔设置；第二调节件30'的第一遮挡部311和第二遮挡部312可 逆时针方向依次间隔设置。第一遮挡部311可配置成允许其完全遮蔽一个出风口212。第二遮挡部312可配置成允许其完全遮蔽两个出风口212。第一遮挡部311和第二遮挡部312之间的间隔可配置成允许其完全暴露一个出风口212。
图3至图9分别示出根据本发明实施例的分路送风装置100中第一调节件30和第二调节件30'处在不同转动位置处的示意性局部结构图。由于第一调节件30带动第二调节件30'，以同步反向运动，壳体20的第一半部21中每个出风口212的状态与壳体20的第二半部21'中相对应的出风口212的状态相同，下面就以第一半部21中调节件的运动为例，介绍第一半部21和第二半部21'的第一出风口213、第二出风口214和第三出风口215的开闭状态。具体地，当第一调节件30的第一遮挡部311和第二遮挡部312转动到如图3所示位置处时，第一半部21和第二半部21'的第一出风口213、第二出风口214和第三出风口215均处于打开状态。当第一调节件30的第一遮挡部311和第二遮挡部312转动到如图4所示位置处时，第二遮挡部312完全遮蔽第二出风口214和第三出风口215，可使第一出风口213处于完全暴露状态。当第一调节件30的第一遮挡部311和第二遮挡部312转动到如图5所示位置处时，第一遮挡部311可完全遮蔽第三出风口215，第二遮挡部312可完全遮蔽第一出风口213，两个遮挡部31之间的间隔可使第二出风口214处于完全暴露状态。当第一调节件30的第一遮挡部311和第二遮挡部312转动到如图6所示位置处时，第二遮挡部312可完全遮蔽第一出风口213和第二出风口214，两个遮挡部31之间的间隔可使第三出风口215处于完全暴露状态。
当第一调节件30的第一遮挡部311和第二遮挡部312转动到如图7所示位置处时，第二遮挡部312可仅完全遮蔽第三出风口215，第一出风口213和第二出风口214处于完全暴露状态。当第一调节件30的第一遮挡部311和第二遮挡部312转动到如图8所示位置处时，第一遮挡部311可完全遮蔽第一出风口213，第二出风口214和第三出风口215处于完全暴露状态。当第一调节件30的第一遮挡部311和第二遮挡部312转动到如图9所示位置处时，第一遮挡部311可完全遮蔽第二出风口214，第三出风口215处于完全暴露状态，两个遮挡部31之间的间隔可使第一出风口213处于完全暴露状态。当然，第一调节件30的第一遮挡部311和第二遮挡部312也可转动 到使第一出风口213的一半遮蔽、第二出风口214和第三出风口215处于完全暴露状态的转动位置处，如第一遮挡部311仅仅遮蔽住第一出风口213的远离第二出风口214的一半的位置处。第一遮挡部311和第二遮挡部312也可转动到使第一出风口213完全遮蔽、第二出风口214一半遮蔽和第三出风口215处于完全暴露状态的转动位置处，如第二遮挡部312完全遮蔽住第一出风口213，以及遮蔽住第二出风口214的远离第三出风口215的一半的位置处。
在本发明的一些实施例中，壳体20还可包括一个或多个肋板23和分配器盖24。每个肋板23从基座22的一个表面延伸出。分配器盖24可盖设于一个或多个肋板23的远离基座22的一端。基座22、一个或多个肋板23和分配器盖24限定出进风通道25、多个第一出风通道26和多个第二出风通道26'。进风通道25可与每个进风口211连通，且关于几何对称面对称设置。多个第一出风通道26分别与第一半部21的多个出风口212连通。多个第二出风通道26'分别与第二半部21'的多个出风口212连通，且多个第二出风通道26'与多个第一出风通道26关于几何对称面对称设置。进一步地，基座22、一个或多个肋板23和分配器盖24以及两个圆弧形周壁之间也可限定出用于容纳电机40的容纳空间27。基座22可为方形结构。
图10是根据本发明一个实施例的冰箱的示意性结构图，图11是根据本发明一个实施例的分路送风装置100安装于风道组件300的示意性结构图。如图10和图11所示，本发明实施例还提供了一种冰箱，其具有储物间室200，该储物间室200也可被搁物板或搁物架分隔成多个储物空间。进一步地，该冰箱中也设置有风道组件300和设置于风道组件300内的、上述任一实施例中的分路送风装置100。
风道组件300可关于冰箱的储物间室200的纵向对称面对称设置，且其内限定有进风风道310和多个出风风道320，每个出风风道320可具有一个或多个冷风出口。多个出风风道320配置成使流出风道组件300的气流分别从储物间室200的间室壁上的、关于纵向对称面对称的多个位置处进入储物间室200。例如，风道组件300具有位于纵向对称面一侧的四个第一冷风出口，以及位于纵向对称面另一侧的四个第二冷风出口，四个第一冷风出口与四个第二冷风出口关于纵向对称面对称设置，以使流出风道组件300的气流分别从储物间室200的间室壁上的、关于纵向对称面对称的多个位置处进入 储物间室200。

如图11所示，在本发明的一些实施例中，邻近纵向对称面的两个出风风道320相互连通，形成一关于纵向对称面对称的出风风道空间。优选地，邻近纵向对称面的两个出风风道320可设计成一个第一总风道，可便于风道组件300的加工。
具体地，如图10和图11所示，冰箱可包括多个储物间室200，风道组件300用于向冷藏室210输送气流。图10中的实线箭头表示气流在一个或多个储物间室200内的流向，虚线箭头表示气流在风道内的流向。分路送风装置100中壳体20的第一半部21和第二半部21'的出风口212的数量均可为3个，如第一出风口213、第二出风口214和第三出风口215。出风风道320的数量可为6个，如分别与两个第一出风口213连通的两个第一风道3201、分别与两个第二出风口214连通的两个第二风道3202、分别与两个第三出风口215连通的两个第三风道3203。两个第一风道3201邻近纵向对称面设置，且可相互连通，如图10所示；两个第一风道3201之间也可不设置分隔板，使两个第一风道3201为一个第一总风道，如图11所示。每个第一风道3201可具有两个冷风出口，设置在该冷藏室210后壁的上部。每个第二风道3202可具有一个冷风出口，设置在该冷藏室210后壁的中部。每个第三风道3203具有一个冷风出口，设置在冷藏室210后壁的下部。进一步地，也可使用两个搁物架将该冷藏室210分割为三个储物空间，每个第一风道3201可与上部的储物空间连通，每个第二风道3202可与中部的储物空间连通，每个第三风道3203可与下部的储物空间连通。在该实施例中，多个储物间室200还可包括速冻室220、冷冻室230。
本发明实施例中的冰箱可根据冰箱储物间室200(如冷藏室210)各层位置处的冷量是否充足，控制冷风从相应的出风风道320流入该层位置处，以使冷风可被合理分配至储物间室200不同的位置处，增强了冰箱的保鲜性能和运行效率。该分路送风装置100能够实现对出风风道320风向、风量的 调节，冰箱的该储物间室200内哪层需要冷风就开启那层的冷风出口，不需要冷风就关闭。从而控制冰箱内温度的恒定性，为冰箱内的食物提供最佳的储存环境，减少食物的营养流失，并且能够减小冰箱的耗电，节约能源。此外，每层的冷风出口的数量可为至少两个，关于该储物间室200的纵向对称面对称设置，以使冰箱储物间室200的该层左右两侧受冷均匀。
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。
