Description

冰箱及用于冰箱的分路送风装置 技术领域
本发明涉及冰箱领域，特别是涉及一种冰箱及用于冰箱的分路送风装置。
背景技术
一般而言，风冷冰箱通过内置的蒸发器产生冷风，冷风通过风道循环流动至冰箱的各个储物间室实现制冷。对于风冷冰箱，食物的保鲜性能很大程度取决于储物间室内气流循环是否合理。如果冷风经风道随机流动，容易造成进入各储物间室内的风量过多或不足，使储物间室内的温度分布不均衡，冰箱的运行效率也会降低。因此，有必要对进入各储物间室内的冷风进行精确地流向分配和流量控制。
同样地，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。
为此，现有技术中在冰箱的箱体背部的风道处设置有分路送风装置，其进风口连通冷风入口，其多个出风口分别连通通向各个储物空间。由于储物间室内易出现冷气下沉，热量上串的现象，所以要求对储物间室中每一层的风量精确分配，然而现有技术中的分路送风装置很难实现精确的流向分配和流量控制，且现有技术中采用的离心风机由于在出风位置具有遮挡导致出风量难以满足要求，给用户造成了一定困扰。
发明内容
鉴于上述问题，提出了本发明以便提供一种克服上述问题或者至少部分地解决上述问题的冰箱及用于冰箱的分路送风装置。
本发明的一个目的是要控制分路送风装置的送风配比。
本发明的一个进一步的目的是要提高分路送风装置的送风量。
特别地，本发明提供了一种用于冰箱的分路送风装置，包括：
壳体，其具有进风口和多个出风口；
调节件，配置成受控地对每个出风口进行完全遮蔽、部分遮蔽或完全暴露，以调整多个出风口各自的出风面积；
供风装置，设置于壳体内，配置成促使气流从进风口流入壳体并经由多个出风口中的一个或多个流出壳体；
分流装置，设置于壳体内，配置成引导流出供风装置的气流，且使流出供风装置的气流以预定比例流向每个出风口。
可选地，供风装置为离心叶轮。
可选地，壳体包括基座和分配器盖；分配器盖具有盖板和从盖板的边缘向基座延伸的周壁，盖板上开设有进风口，周壁开设有多个出风口，且周壁的远离盖板的一端安装于基座。
可选地，分流装置包括多个导流板，每个导流板从盖板的内表面向基座延伸；且每个导流板配置成使流出供风装置的气流从该导流板的两侧流向两个相邻的出风口。
可选地，周壁包括第一周壁段，第一周壁段在盖板上的投影为圆弧形；且多个出风口沿基座的周向方向依次设置于第一周壁段。
可选地，调节件包括一个或多个沿周向方向间隔设置的遮挡板，每个遮挡板与第一周壁段同轴设置；调节件绕第一周壁段的轴线可转动地安装于壳体内，以在转动到不同的转动位置处，使一个或多个遮挡板受控地对每个出风口进行完全遮蔽、部分遮蔽或完全暴露；且每个导流板的靠近周壁的一端与周壁间隔设置，以限定出允许调节件转动的让位通道。
可选地，调节件还包括至少一个流通部，遮挡板和流通部沿基座的周向方向依次设置，且一个或多个遮挡板与至少一个流通部围成一筒状结构，每个流通部上开设有一个或多个流通孔；调节件还配置成在其转动到不同的转动位置处时，使气流经由至少一个流通部上的流通孔进入被部分遮蔽或完全暴露的出风口。
可选地，供风装置的旋转轴线与基座的轴线平行且间隔设置，以使供风装置偏置于壳体内。
可选地，分路送风装置还包括：聚流板，从盖板的内表面向基座延伸，配置成促使流出供风装置的气流流向多个出风口。
本发明还提供了一种冰箱，包括：
风道组件，包括冷风入口和多个冷风出口；以及
上述任一种分路送风装置，设置于风道组件内，且分路送风装置的进风口连通冷风入口，分路送风装置的每个出风口分别连通风道组件的多个冷风出口中的至少一个。
本发明的冰箱及用于冰箱的分路送风装置由于具有分流装置，可引导流出供风装置的气流以预定比例流向每个出风口，且因为调节件对多个出风口进行可控地遮蔽，实现了对出风风道进行选择以及可能再次地每个出风风道内出风风量进行调节，从而可根据不同储物间室的冷量需求或者一个储物间室的不同位置处的冷量需求对冷风进行精确地流向分配和流量控制，增强冰箱的保鲜性能和运行效率。
进一步地，由于供风装置采用离心叶轮，使其维修方便，通风效果好。且供风装置的旋转轴线与基座的轴线平行且间隔设置，以使供风装置偏置于壳体内，以减少由于离心叶轮风向位置具有阻挡而损失的风量，增大了分路送风装置的最大出风量，满足了冰箱储物间室的冷量需求。

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的示意性结构图，图2是图1所示分路送风装置的示意性爆炸图，图3是图1所示分路送风装置的示意性内部结构图，图14是根据本发明一个实施例的冰箱的示意性结构图，如图1至图3并结合图14所示，本发明的实施例提供了一 种用于冰箱1的分路送风装置10，该分路送风装置10可包括壳体100、调节件200、供风装置300以及分流装置400。
壳体100可具有进风口124和多个出风口，以使气流可从进风口124进入壳体100内，并可从多个出风口流出该壳体100。具体地，壳体可包括基座110和分配器盖120，分配器盖120具有盖板和从盖板的边缘向基座110延伸的周壁，盖板上开设有进风口124，周壁上开设有多个出风口，且周壁的远离盖板的一端安装于基座110。具体地，基座110的边缘可具有向分配器盖120延伸的多个连接臂112，每个连接臂112的内表面上形成有卡槽或凸起，周壁的外表面上形成有分别与每个卡槽配合的多个凸起或分别与每个凸起配合的卡槽，以使分配器盖120卡接于基座110。
在一些优选实施方式中，基座110的内表面还形成有安装凹槽111，供风装置300安装于安装凹槽111，例如离心叶轮安装于安装凹槽111的底表面。周壁可包括第一周壁段125和第二周壁段126，且优选第一周壁段125在盖板上的投影为圆弧形。第一周壁段125可开设有多个出风口。
调节件200可设置于壳体100内部，配置成受控地对每个出风口进行完全遮蔽、部分遮蔽或完全暴露，以调整多个出风口各自的出风面积。例如，调节件200包括一个或多个沿周向方向间隔设置的遮挡板220，每个遮挡板220与第一周壁段125同轴设置；调节件200绕第一周壁段125的轴线可转动地安装于壳体100内，以在转动到不同的转动位置处，使一个或多个遮挡板受控地对每个出风口进行完全遮蔽、部分遮蔽或完全暴露。进一步地，调节件200还可包括至少一个流通部210，遮挡板220和流通部210沿基座110的周向方向依次设置，且一个或多个遮挡板220与至少一个流通部210围成一筒状结构，每个流通部210上开设有一个或多个流通孔。调节件200还配置成在其转动到不同的转动位置处时，使气流经由至少一个流通部210上的流通孔进入被部分遮蔽或完全暴露的出风口。
供风装置300可设置于壳体100内，配置成促使气流从进风口124流入壳体100并经由多个出风口中的一个或多个流出壳体100。这样设置不仅可使分路送风装置10在单系统冰箱中，再次为蒸发器室内送风装置吹送出的气流的提供动力，以提高了该分路送风装置10的送风效率，也可使该分路送风装置10可独立进风，以使该分路送风装置10特别适用于双系统或多系统冰箱1。在一些实施方式中，供风装置300可以为离心叶轮，设置于壳体100内，使其结构节凑，维修方便，通风效果好。
分流装置400可设置于壳体100内，配置成引导流出供风装置300的气流，且使流出供风装置300的气流以预定比例流向每个出风口。在该实施例中，分流装置400和调节件200相配 合地对分路送风装置10进行控制，以利用分流装置400的分流作用和调节件200对多个出风口进行可控地遮蔽的功能，实现对出风进行选择以及每个出风口出风风量的调节，从而可根据不同储物间室的冷量需求或者一个储物间室的不同位置处的冷量需求对冷风进行精确地流向分配和流量控制。
在本发明的一些实施例中，分流装置400可包括多个导流板，每个导流板从盖板的内表面向所述基座110延伸。且每个导流板配置成使流出供风装置300的气流从该导流板的两侧流向两个相邻的出风口，也就是说，每两个相邻的出风口之间可设置一个导流板。进一步地，每个导流板的靠近周壁的一端与周壁间隔设置，以限定出允许调节件200转动的让位通道。
图4和图5分别为本发明的分路送风装置的示意性局部结构图，供风装置300的旋转轴线可与基座110的轴线平行且间隔设置，以使供风装置300偏置于壳体100内。分路送风装置10还可以包括聚流板500，其从盖板的内表面向基座110延伸，配置成促使流出供风装置300的气流流向多个出风口，在一些优选实施方式中，聚流板500为弧形，其一端指向第三出风口的远离第一出风口121的一侧，另一端靠近离心叶轮，以减少由于离心叶轮风向位置具有阻挡而损失的风量，进而将离心叶轮排出的部分气流平滑地引导至多个出风口处，增大了分路送风装置10的出风量，满足了冰箱1储物间室的冷量需求。
在一些进一步的实施例中，出风口的数量为三个，沿基座110的周向方向依次间隔设置。这三个出风口包括第一出风口121、第二出风口122和第三出风口123，沿基座110的周向设置。导流板可设置有两个，分别为第一导流板410和第二导流板420。具体地，第一导流板410和第二导流板420均为长板状，且第一导流板410朝向供风装置300设置，第二导流板420的长度大于第一导流板410的长度，其朝向壳体100内部的远离供风装置300一侧延伸，以引导流出供风装置300的气流，且使流出供风装置300的气流以预定比例流向每个出风口。三个出风口和聚流板500可将第一出风口121、第二出风口122和第三出风口123的风量配比限定为：65％：25％：10％，以精确量化不同储物间室或相同储物间室的不同位置处的冷风风量。
在该实施例中，遮挡板220和流通部210的数量为两个。两个遮挡板220包括第一遮挡板221和第二遮挡板222。两个流通部210包括第一流通部211和第二流通部212，沿基座110的周向方向且可沿逆时针方向依次间隔设置。第一遮挡板221配置成允许其完全遮蔽一个出风口。第二遮挡板222配置成允许其至少完全遮蔽两个出风口，如第二遮挡板222可至少完全遮蔽三个出风口。第一流通部211上开设有一个流通孔，第二流通部212上开设有沿基座110的周向方向依次间隔设置的三个流通孔，每个流通孔配置成允许其完全暴露一个出风口，且第二流通部212上的三个流通孔配置成允许其完全暴露三个出风口。
如图6至图13所示，当第一遮挡板221和第二遮挡板222转动到如图6所示位置处时，第二流通部212上的三个流通孔可使第一出风口121、第二出风口122和第三出风口123均处于打开状态。当第一遮挡板221和第二遮挡板222转动到如图7所示位置处时，第二遮挡板221可完全遮蔽第二出风口122和第三出风口123，第二流通部212上的流通孔可使第一出风口121处于完全暴露状态。当第一遮挡板221和第二遮挡板222转动到如图8所示位置处时，第一遮挡板221可完全遮蔽第三出风口123，第二遮挡板222可完全遮蔽第一出风口121，第一流通部211上的流通孔可使第二出风口122处于完全暴露状态。当第一遮挡板221和第二遮挡板222转动到如图9所示位置处时，第二遮挡板222完全遮蔽第一出风口121和第二出风口122，第一流通部211上的流通孔可使第三出风口123处于完全暴露状态。
当第一遮挡板221和第二遮挡板222转动到如图10所示位置处时，第二遮挡板222可完全遮蔽第三出风口123，第二流通部212上的两个流通孔可使第一出风口121和第二出风口122处于完全暴露状态。当第一遮挡板221和第二遮挡板222转动到如图11所示位置处时，第一遮挡板221可仅完全遮蔽第一出风口121，第二流通部212上的两个流通孔可使第二出风口122和第三出风口123处于完全暴露状态。当第一遮挡板221和第二遮挡板222转动到如图12所示位置处时，第一遮挡板221可完全遮蔽第二出风口122，第一流通部211上的流通孔可使可使第一出风口121处于完全暴露状态，第二流通部212上的一个流通孔可使第三出风口123处于完全暴露状态。当第一遮挡板221和第二遮挡板222转动到如图13所示位置处时，第二遮挡板222可完全遮蔽第一出风口121、第二出风口122和第三出风口123。当然，第一遮挡板221和第二遮挡板222也可转动到其他的转动位置处，以对风路和风量进行调节。
在本发明的另一些进一步的实施例中，调节件200可只有遮挡板220，且当只有一个遮挡板220的情况下，遮挡板220的两侧均允许气流通过。当调节件200有多个遮挡板220的情况下，每两个相邻的遮挡板220之间的间隔均可允许气流通过。
具体地，在该实施方式中，出风口的数量为三个，沿基座110的周向方向依次间隔设置。这三个出风口包括第一出风口121、第二出风口122和第三出风口123，沿基座110的周向方向且可沿逆时针方向依次间隔设置。遮挡板220的数量为两个。两个遮挡板220分别为第一遮挡板221和第二遮挡板222，可沿基座110的周向方向且可沿逆时针方向依次间隔设置。第一遮挡板221可配置成允许其完全遮蔽一个出风口。第二遮挡板222可配置成允许其完全遮蔽两个出风口。第一遮挡板221和第二遮挡板222之间的间隔可配置成允许其完全暴露一个出风口。当第一遮挡板221和第二遮挡板222均不遮蔽出风口时，第一出风口121、第二出风口122和第三出风口123均处于打开状态。当第二遮挡板222完全遮蔽第二出风口122和第三出风口123 时，两个遮挡板220之间的间隔可使第一出风口121处于完全暴露状态。当第一遮挡板221可完全遮蔽第一出风口121时，第二遮挡板222可完全遮蔽第三出风口123，两个遮挡板220之间的间隔可使第二出风口122处于完全暴露状态。当第二遮挡板222可完全遮蔽第一出风口121和第二出风口122时，可使第三出风口123处于完全暴露状态。当第一遮挡板221可完全遮蔽第三出风口123时，第一出风口121和第二出风口122处于完全暴露状态。当第二遮挡板222仅可完全遮蔽第一出风口121时，第二出风口122和第三出风口123处于完全暴露状态。当第一遮挡板221可完全遮蔽第二出风口122时，第一出风口121处于完全暴露状态，两个遮挡板220之间的间隔可使第三出风口123处于完全暴露状态。
在本发明的一些实施例中，壳体100外侧还可安装有驱动装置600，具体地，安装于第二周壁段126与其对应盖板限定的空间内。驱动装置600可以包括电机610和安装于电机610转轴上的齿轮620，且结合图2所示，调节件200的上设置有与齿轮620相配合的齿圈230，以通过齿轮620的转动带动调节件200转动，其结构简单、紧凑，具有广泛的普及型。
在本发明的一些实施例中，在分路送风装置10的分配器盖120的盖板出开设有出水口127，具体地，出水口127设置于聚流板500的内侧处。由于分路送风装置10及冰箱1的风道内不完全密封，会有少量的水汽随冷风进入到风道内部，导致分路送风装置10内产生积水，甚至形成结冰，影响了冰箱1的使用性能。本实施例的出水口127可使水汽随风机转动在内壁沉积下来，沿着出水口127流出来，可防止结冰。
在本发明的一些实施例中，调节件200的遮挡板220在遮挡出风口时，可使遮挡板220的外表面贴靠于第一周壁段125的内表面。而在一些替代性实施例中，为了便于调节件200的转动，可通过使每个遮挡板220与第一周壁段125之间的距离稍稍变大来解决，然而在遮挡板220与第一周壁段125之间的距离增大的情况下，会导致冷风渗漏，从而不能起到完全有效的遮蔽。因此，本发明的实施例中的分路送风装置10还可包括密封装置，其配置成至少部分地阻碍气流经每个遮挡板220的外表面与第一周壁段125的内表面之间的间隙流向每个出风口。具体地，密封装置可包括至少两个密封垫，每个密封垫沿平行于调节件200的旋转轴线的方向延伸。每个遮挡板220的弧形外表面的沿其转动方向的两端均具有一个密封垫。在调节件200包括遮挡板220和流通部210的情况下，密封装置还可包括其余的密封垫，可设置在每个流通部210上的每两个相邻的流通孔之间。
图14是根据本发明一个实施例的冰箱的示意性结构图，图15是图14所示冰箱的示意性局部结构图，如图14及图15所示，本发明的实施例还提供了一种冰箱1。该冰箱1可以包括风道组件20和分路送风装置10，具体地，风道组件20包括冷风入口21和多个冷风出口。分路送风 装置10可设置于设置于风道组件20内，且分路送风装置10的进风口124连通冷风入口，分路送风装置10的每个出风口连通风道组件20的多个冷风出口中的至少一个。
如图15所示，在一些优选实施例中，冰箱1的风道组件20的多个冷风出口组沿竖直方向被布置成多层，从而使风道具有多个出风层，以使冷风由风道组件20的多个高度处出风。具体地，出风层为三个，分别为第一出风层、第二出风层和第三出风层，每个出风层可具有至少一个冷风出口，每个出风层的冷风出口分别经由与该出风层相应的出风风道与分路送风装置10的第一出风口121、第二出风口122以及第三出风口123相连通，以将从分路送风装置10排出的冷风分别送至冰箱1的上下设置的多个储物间室或一个储物间室的间室壁的上部、中部和下部，以满足冰箱1储物间室的冷量需求，提高冰箱1的整体性能。在该实施例中，由于处于同一层的冷风出口与一个分路送风装置10的一个出风口连通，且处于同一层的冷风出口的数量可为至少一个，则说明设置于风道组件20中的分路送风装置10的每个出风口可连通风道组件20的多个冷风出口中的至少一个。在一些优选实施方式中，第一出风层可包括多个冷风出口，例如，4个冷风出口22，且分别设置于风道组件20的上部和其侧壁的上部，则第一出风口121可连通多个冷风出口，如4个。再例如，第二出风层包括两个冷风出口23，分别设置于风道组件20侧壁的两侧中上部，则第二出风口122可连通2个冷风出口。第三出风层可仅具有一个冷风出口24，设置于风道组件20的一侧中部，则第三出风口123仅连通1个冷风出口。
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。
