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。为了解决上述问题，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，其多个出风口通过风道通向一个储物间室的不同位置处，以向多个储物空间送风。然而，大部分具有双系统冷藏室的冰箱除了多层搁物架还设置有一个干燥间，且干燥间需要单独控制供风，通常是通过在风道设置控制装置(如电动风门)来控制干燥室送风风道的开闭，由于在控制时需要控制电动风门和分路送风装置，显著增大了冰箱的控制复杂程度，此外还增加了冰箱的耗电。

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的示意性结构图，图2是图1所示的分路送风装置的一个示意性爆炸图，图3是图1所示的分路送风装置的另一个示意性爆炸图，图16是根据本发明一个实施例的冰箱的示意性结构图。结合图1、图2、图3及图16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、挡板700和联动装置800。
壳体100可具有进风口124、第一出风口129和多个第二出风口，以使蒸发器制得的冷风可经由进风口124进入该分路送风装置10的壳体100内，并可从第一出风口129和/或多个第二出风口流出，最终流至冰箱1的多个储物间室30或从一个储物间室30的多个位置处流入该储物间室30。特别地，在一些实施方式中，第一出风口129最终可与冰箱的干燥室连通，多个第二出风口可与一个储物间室的多个位置处连通。
调节件200可转动地设置于壳体100内，以在不同的转动位置处对每个第二出风口进行完全遮蔽、部分遮蔽或完全暴露，从而调整多个第二出风口各自的出风面积，进一步地能够对进入各储物间室30内的冷风或一个储物间室30的每个位置处的冷风进行精确地分配，提高了冰箱1的制冷性能。并且，调节件200可包括转盘，且调节件200绕转盘的轴线可转动地设置于壳体100内。
挡板700可转动地安装于第一出风口129处，以在第一出风口129需要关闭时遮盖第一出风口129。
联动装置800可配置成将调节件200的旋转运动传递至挡板700，以使挡板700运动从而开启或关闭第一出风口129，进而使分路送风装置10可同时控制第一出风口129和多个第二出风口的开闭，进而可降低冰箱控制的复杂程度。
在本发明的一些实施例中，壳体100可包括基板110和分配器盖120。分配器盖120具有盖板和周壁125。周壁125从所述盖板向所述盖板的一侧延伸且与所述转盘同轴设置。所述周壁125上形成有所述多个第二出风口。基板110设置于所述周壁125的远离所述盖板的一端，例如，基板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卡接于基板110。调节件200的转盘可设置于所述周壁125的远离所述盖板的一端。
特别地，在该实施中，周壁125上还开设有连通孔，且壳体100还包括三个风道壁128，设置于所述周壁125上配置成限定连通所述连通孔的出风道，而且所述三个风道壁128的远离所述周壁的一端配置成限定所述第一出风口129。具体地，三个风道壁128可与基板110共同围成所述出风道。
在本发明的一些实施例中，联动装置800可包括传动杆810和安装于所述挡板700的齿轮820，所述传动杆810上具有与所述齿轮820啮合的齿牙，且所述传动杆810配置成在所述转盘驱动下沿所述传动杆810的长度方向移动，以带动所述挡板700转动。在一些替代性实施例中，联动装置800包括可两个连杆，一个连杆的一端枢接于挡板700的远离挡板700转轴的一侧，另一端与另一连杆的一端枢接，另一连杆的另一端配置成在转盘的驱动下沿连杆的长度方向移动，以带动挡板700转动，本实施方式无需齿轮结构，结构简单。
在本发明的一些实施例中，送风道可沿转盘的径向方向延伸，传动杆810也设置为沿转盘的径向方向延伸。为了便于传动杆810的安装，分路送风装置10还可包括固定件900，固定件900安装于基板110上，其上开设有供传动杆810滑动的凹槽，以与基板110的内表面限定出引导传动杆810运动的导向通道，进而使联动装置800的传动更加稳定。
为了便于转盘驱动传动杆810移动，转盘的一个侧面上可设置有滑槽830，且传动杆810一端还具有插入滑槽830的凸起811，以在转盘转动时，凸起811在滑槽830内滑动且在滑槽830的作用下可沿传动杆810的长度方向移动。
如图3所示，在该实施例的一些实施方式中，滑槽830包括第一滑槽段和与其相连的第二滑槽段，具体地，第一滑槽段作为滑槽830的主体部分，呈与转盘同心的圆弧形，第二滑槽段从第一滑槽段的一端延伸至第一滑槽段的另一端的径向内侧，以在调节件200在对每个第二出风口的出风面积进行调整时，利用第一滑槽段的特性，不会引起凸起811的移动，进而不会关闭第一出风口129；以及在需要关闭第一进风口124时，利用第二滑槽段的特性，使凸起811拉动传动杆810，进而联动挡板800关闭第一出风口129。
如图4所示，在该实施例的另一些实施方式中，滑槽830可包括第三滑槽段831、第四滑槽段833和第五滑槽段832，其中第三滑槽段831和第四滑槽段833作为滑槽830的主体部分设置于转盘上，且均呈与转盘同心的圆弧形并且等半径设置。第五滑槽段832从第三滑槽段831的一端朝靠近转盘圆心的方向延伸后又朝远离转盘圆心的方向延伸至第四滑槽段833的靠近第三滑槽段831的上述一端的端部。优选地，如图12及图13所示，第五滑槽段832的中间位置处和位于其逆时针方向的第四滑槽段833的一端与调节件200圆心形成的两条连线的夹角优选为135°，且滑槽830的两端与调节件200圆心形成的两条连线的夹角优选为31.5°，以量 化凸起811在滑槽830内的滑动过程。
在本发明的一些实施例中，调节件200还可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可从转盘的另一侧面(转盘朝向盖板的侧面)延伸出，并于与周壁125同轴设置。调节件200绕周壁125的轴线在转动到不同的转动位置处，可使一个或多个遮挡板220受控地对每个第二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沿转盘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第二出风口。
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的外表面贴靠于周壁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与周壁125之间的距离稍稍变大来解决，然而在遮挡板220与周壁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的外表面与周壁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。
在本发明的一些实施例中，盖板上开设有进风口124。分路送风装置10还可包括有离心叶轮(图中未示出)，离心叶轮可设置于壳体100内，配置成促使气流从进风口124流入壳体100并经由第一出风口129和多个第二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。在一些替代性实施例中，分路送风装置10可不设置离心叶轮，进风口可设置于周壁125上，以使分路送风装置10从壳体的周壁125上进风。
在该实施例中，所述转盘的中央具有通孔；所述离心叶轮经由所述通孔安装于所述基板110的内表面。例如，基板110的内表面还形成有安装凹槽111，离心叶轮安装于安装凹槽111。进一步地，离心叶轮的旋转轴线可与基板110的轴线平行且间隔设置，以使离心叶轮偏置于壳体100内。分路送风装置10还可以包括聚流板500，聚流板500从盖板的内表面向基板110 延伸，配置成促使流出离心叶轮的气流流向第一出风口129和多个第二出风口，在一些优选实施方式中，聚流板500为弧形，其一端指向连通孔的远离第二出风口121的边缘处，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进行平滑地引导，增大了分路送风装置10的出风量，满足了冰箱1储物间室30的冷量需求。
在本发明的一些实施例中，分路送风装置10还可包括分流装置400，分流装置400可设置于壳体100内，配置成引导流出离心叶轮的气流，且使流出离心叶轮的气流以预定比例流向第一出风口129和每个第二出风口。分流装置400。挡板700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、挡板700对第一出风口129的开闭控制和调节件200对多个第二出风口进行可控地遮蔽的功能，实现对出风进行选择以及第一出风口129和每个第二出风口出风风量的调节。例如，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板110延伸。且每个导流板配置成使流出离心叶轮的气流从该导流板的两侧流向两个相邻的第二出风口，也就是说，每两个相邻的第二出风口之间可设置一个导流板。为了便于调节件200转动，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。
在本发明的一些实施例中，周壁外侧还可安装有驱动装置600。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的盖板上开设有出水口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。
在本发明的一些更加具体的实施例中，第二出风口的数量可为三个，沿基板110的周向方向依次间隔设置。三个第二出风口分别为第二出风口121、第二出风口122和第二出风口123，沿基板110的周向设置。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，沿基板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第二出风口。第二遮挡板222配置成允许其至少完全遮蔽两个第二出风口，如第二遮挡板222 可至少完全遮蔽三个第二出风口。第一流通部211上开设有一个流通孔，第二流通部212上开设有沿基板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第二出风口，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第二出风口。
在该实施例中，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。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朝向离心叶轮设置，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内部的远离离心叶轮一侧延伸，以引导流出离心叶轮的气流，且使流出离心叶轮的气流以预定比例流向第一出风口和第二出风口。
图4至图14分别是根据本发明一个实施例的分路送风装置的调节状态示意图，其中图4至图11分别示出了分路送风装置中调节件中遮挡板处于多个位置以调节多个第二出风口。具体地，当第一遮挡板221和第二遮挡板222转动到如图4所示位置处时，第二流通部212上的三个流通孔可使第二出风口121、第二出风口122和第二出风口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5所示位置处时，第二遮挡板221可完全遮蔽第二出风口122和第二出风口123，第二流通部212上的流通孔可使第二出风口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6所示位置处时，第一遮挡板221可完全遮蔽第二出风口123，第二遮挡板222可完全遮蔽第二出风口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7所示位置处时，第二遮挡板222完全遮蔽第二出风口121和第二出风口122，第一流通部211上的流通孔可使第二出风口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8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二出风口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9所示位置处时，第一遮挡板221可仅完全遮蔽第二出风口121，第二流通部212上的两个流通孔可使第二出风口122和第二出风口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二出风口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二出风口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11所示位置处时，第二遮挡板222可完全遮蔽第二出风口121、第二出风口122和第二出风口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。
图4至图14分别是根据本发明一个实施例的分路送风装置的调节状态示意图，其中，图12至图14分别示出了分路送风装置中挡板处于多个位置以调节第一出风口。具体地，如图12 所示，传动杆810上的凸起811位于第三滑槽段831的的止档处，此时第二出风口121和第二出风口122开启，第二出风口123关闭。如图13所示，传动杆810上的凸起811位于第四滑槽段833内，此时第二出风口121、第二出风口122和第二出风口123均关闭，第一出风口129开启。如图14所示，传动杆810上的凸起811位于第五滑槽段832的一端。此时第二出风口121、第二出风口122和第二出风口123均开启，第一出风口129关闭。总之，在调节件200及联动装置800的运动过程中，只有当传动杆810上的凸起811位于第四滑槽段833内时，第一出风口129开启。
图15是根据本发明一个实施例的冰箱的示意性结构图，图16是图15所示冰箱的示意性局部结构图，如图15及图16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、分路送风装置10和干燥室以及一个或多个储物间室30。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的第一出风口129和每个第二出风口连通风道组件20的多个冷风出口中的至少一个。每个储物间室30内可被多个搁物架31分为多个储物空间。分路送风装置10可通过第一出风口将冷风输送到干燥室内，以及可通过多个第二出风口风道组件将冷气送入一个储物间室30的不同储物空间或多个储物间室30内。
如图17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，出风层为四个，分别为第一出风层、第二出风层、第三出风层和第四出风层，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的第一出风口或第二出风口相连通。第一出风层、第二出风层和第三出风层的冷风出口可分别将从分路送风装置10排出的冷风送至一个储物间室30的间室壁的上部、中部和下部，以满足冰箱1储物间室30的冷量需求，提高冰箱1的整体性能。第四出风层的至少一个冷风出口可与冰箱的另一储物间室(如干燥室)连通。
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。具体地，第一出风层可包括多个冷风出口，例如，四个冷风出口22，且分别设置于风道组件20的上部和其侧壁的上部，则第二出风口121可连通多个冷风出口，如四个。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可连通两个冷风出口。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，则第二出风口123仅连通一个冷风出口。再例如，第四出风层包括一个冷风出口25，设置于风道组件20的下部，则第一 出风口129仅连通一个冷风出口，以单独对冰箱1的干燥室进行冷风输送及控制。
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。
