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间室的多个冷风出口，且在风道设置控制装置(如电动风门)来控制冷风进口和冷风出口的开闭。然而，此分路送风装置在关闭时由于角度因素导致其电动风门不能完全闭合，导致储物间室过冷，且增加了冰箱的能耗；由于采用电动风门，使分路送风装置结构较复杂，且增加了冰箱的耗电。
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在储物间室不需要冷量时，阻断向其提供冷量的气流通道，防止储物间室内过冷。
本发明的一个进一步的目的是要使分路送风装置的结构及控制方式更简单。
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，可转动地设置于壳体内，以在不同的转动位置处对每个出风口进行完全遮蔽、部分遮蔽或完全暴露，从而调整多个出风口各自的出风面积；
挡板，可转动地安装于进风口处；以及
联动装置，配置成将调节件的旋转运动传递至挡板，以使挡板运动从而开启或关闭进风口。
可选地，调节件包括转盘，且调节件绕转盘的轴线可转动地设置于壳体内。
可选地，联动装置包括传动杆和安装于挡板的齿轮，传动杆上具有与齿轮啮合的齿牙，且传动杆配置成在转盘驱动下沿传动杆的长度方向移动，以带动挡板转动。
可选地，转盘的一个侧面上开设有滑槽，传动杆沿转盘的径向方向延伸，且传动杆一端具有插入滑槽的凸起。
可选地，滑槽包括：第一滑槽段，呈与转盘同心的圆弧形；以及第二滑槽段，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。
可选地，壳体包括：基座；和周壁，从基座向基座的一侧延伸出且与转盘同轴设置，周壁上形成有多个出风口；且调节件还包括一个或多个沿转盘的周向方向间隔设置的遮挡板，每个遮挡板从转盘的另一侧面延伸出，且一个或多个遮挡板配置成在不同的转动位置处对每个出风口进行完全遮蔽、部分遮蔽或完全暴露。
可选地，周壁在基座上的投影为弧形；壳体还包括两个风道壁，设置于基座上且分别从周壁沿基座的周向方向的两端延伸出，以使两个风道壁的远离周壁的一端限定进风口。
可选地，转盘设置于周壁的远离基座的一端。
可选地，出风口的数量为三个，沿基座的周向方向依次间隔设置；遮挡板的数量为两个，两个遮挡板分别为第一遮挡板和第二遮挡板，且第一遮挡板配置成允许其完全遮蔽一个出风口，第二遮挡板配置成允许其完全遮蔽两个出风口，第一遮挡板和第二遮挡板之间的间隔配置成允许其完全暴露一个出风口。
特别地，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；多个冷风出口分别连通冰箱的多个储物间室，或经由冰箱的一个储物间室的间室壁上的、处于不同位置处的多个连通口连通该储物间室；以及
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，分路送风装置的多个出风口分别连通风道组件的多个冷风出口。
在本发明的分路送风装置及冰箱中，由于在进风口处可转动地安装有挡板，在储物间室不需要冷量时，可完全封闭分路送风装置的进风口，从而可阻断向储物间室提供冷量的气流通道，进而防止储物间室内过冷，影响用户使用，且可降低能耗。特别地，在调节件和挡板间安装的联动装置，可使调节器带动挡板转动，以控制进风口的开启或关闭，具体地，可使调节件的转动不仅控制出风口的开启与关闭，还控制进风口的开启和关闭，从而使分路送风装置的控制更加简单和精准。
进一步地，由于本发明的分路送风装置中的联动装置包括具有齿牙的传动杆和安装于挡板的齿轮，使传动杆在转盘驱动下带动挡板转动，实现进风口的开启和关闭，此联动方式可使分路送风装置的结构紧凑、简单，并具有一定推广性。
进一步地，由于本发明的分路送风装置中的转盘通过其上的滑槽和传动杆上的凸起带动传动杆运动，巧妙利用了凸轮机构的原理，使驱动方式简单、方便以及精确，进而使分路送风装置的结构紧凑、简单。
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。

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10的示意性结构图，图2是图1所示的分路送风装置10的示意性爆炸图，图8是从另一角度观察图2所示的分路送风装置10的示意性爆炸图。如图1、图2和图8所示，本实施例提供了一种用于冰箱1的分路送风装置10，可包括壳体100、调节件200、挡板300和联动装置400。
壳体100可具有进风口和多个出风口，以使蒸发器制得的冷风可经由进风口进入该分路送风装置10的壳体100内，并可从多个出风口流出，最终流至冰箱1的多个储物间室或从一个储物间室的多个位置处流入该储物间室。
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出风口进行完全遮蔽、部分遮蔽或完全暴露，从而调整多个出风口各自的出风面积，进一步地能够对进入各储物间室内的冷风或一个储物间室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。
挡板300可转动地安装于进风口处，以在分路送风装置10需要关闭时完全封闭其进风口，从而可防止冷气流经由分路送风装置10进入储物间室，进而可防止储物间室内过冷，影响用户使用，且可降低能耗。
联动装置400可配置成将调节件200的旋转运动传递至挡板300，驱使挡板300开启或关闭进风口，可使调节件200的转动不仅控制出风口的开启与关闭，还控制进风口的开启和关闭，不仅使进风口和出风口的控制更加协调，还可使分路送风装置10的控制更加简单和精准。
在本发明的一些实施例中，调节件200可包括转盘210。具体地，转盘210可以为圆形，调节件200绕转盘210的轴线可转动地设置于壳体100内。进一步地，转盘210外缘还可设置有齿牙，且在壳体100上安装有电机500，电机500通过安装于其输出轴上的齿轮与转盘210外缘的齿牙相啮合带动转盘210转动。
在本发明的一些实施例中，联动装置400可包括传动杆410和安装于挡 板300的齿轮420。具体地，传动杆410上具有与挡板300上齿轮420相啮合的齿牙，且传动杆410配置成在转盘210驱动下沿传动杆410的长度方向移动，以带动挡板300转动。在一些替代性实施例中，联动装置400包括可两个连杆，一个连杆的一端枢接于挡板300的远离挡板300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210的驱动下沿连杆的长度方向移动，以带动挡板300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，转盘210的一个侧面上可具有滑槽430，传动杆410沿转盘210的径向方向延伸，且传动杆410一端还具有插入滑槽430的凸起411，以在转盘210转动时，凸起411在滑槽430内滑动且在滑槽430的作用下可沿传动杆410的长度方向移动，从而带动传动杆410运动，进而引起挡板300的转动。
在该实施例的一些实施方式中，滑槽430包括第一滑槽段431和与其相连的第二滑槽段432，具体地，第一滑槽段431作为滑槽430的主体部分，呈与转盘210同心的圆弧形，第二滑槽段432从第一滑槽段431的一端延伸至第一滑槽段431的另一端的径向内侧，以在调节件200在对每个出风口的出风面积进行调整时，利用第一滑槽段431的特性，不会引起凸起411的移动，进而不会关闭进风口，可保证分路送风装置10的正常工作，以及在需要关闭进风口时，利用第二滑槽段432的特性，使凸起411拉动传动杆410，进而联动挡板300关闭进风口。优选地，第一滑槽段431的两端与转盘210圆心形成的两条连线的夹角为330°，第二滑槽段432的两端与转盘210圆心形成的两条连线的夹角为30°，以量化凸起411在滑槽430内的滑动过程。进一步地，第二滑槽段432可迅速关闭进风口，且不易造成联动装置400的损坏。
在一些替代性实施方式中，滑槽430可包括第三滑槽段和第四滑槽段，第三滑槽段作为滑槽的主体部分，呈与转盘210同心的圆弧形，第四滑槽段从第三滑槽段的一端朝靠近所述转盘210圆心的方向延伸后又朝远离转盘210圆心的方向延伸至第三滑槽段的另一端，以使槽道为首尾相连的槽道，该实施方式在分路送风装置10关闭进风口后需打开出风口时无需电机500反转，方便操作，且结构简易，便于加工。
在本发明的一些实施例中，壳体100包括基座110、周壁120和壳盖140 以及两个风道壁130。具体地，周壁120从基座110的部分边缘向基座110的一侧延伸且与转盘210同轴设置，周壁120上形成有多个出风口。而且，周壁120在基座110上的投影优选为弧形，两个风道壁130设置于基座110上且分别从周壁120沿基座110的周向方向的两端延伸出，以使两个风道壁130限定分路送风装置10的进风风道，且两个风道壁130的远离周壁120的一端限定进风口。两个风道壁130可沿传动杆410的长度方向分别从周壁120沿基座110的周向方向的两端延伸出。并且，转盘210设置于周壁120的远离基座110的一端。壳盖140安装于周壁120和风道壁130的远离基座110的一端，且与周壁120和风道壁130卡接。
在该实施例中，调节件200还可包括一个或多个沿转盘210的周向方向间隔设置的遮挡板220，每个遮挡板220从转盘210的另一侧面(即与滑槽430所处侧面反向的侧面)延伸出，且一个或多个遮挡板220配置成在不同的转动位置处对每个出风口进行完全遮蔽、部分遮蔽或完全暴露，以可控地改变出风口的出风面积，实现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。
例如，在该实施例中，出风口的数量为三个，沿基座110的周向方向依次间隔设置于周壁120上，分别为第一出风口121、第二出风口122和第三出风口123；遮挡板220的数量为两个，且两个遮挡板220分别为第一遮挡板221和第二遮挡板222，其中第一遮挡板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转动均未遮挡三个出风口时，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。当第二遮挡板222完全遮蔽第二出风口122和第三出风口123，可使第一出风口121处于完全暴露状态。当第一遮挡板221完全遮蔽第三出风口123，第二遮挡板222完全遮蔽第一出风口121时，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完全遮蔽第一出风口121和第二出风口122时，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。
当第二遮挡板222可仅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。当第一遮挡板221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完全遮蔽第二出风口122时，第三出风口123处于完全暴露状态，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。
当然，第一遮挡板221和第二遮挡板222也可转动到使第一出风口121的一半遮蔽、第二出风口122和第三出风口123处于完全暴露状态的转动位置处，如第一遮挡板221仅仅遮蔽住第一出风口121的远离第二出风口122的一半的位置处。第一遮挡板221和第二遮挡板222也可转动到使第一出风口121完全遮蔽、第二出风口122一半遮蔽和第三出风口123处于完全暴露状态的转动位置处，如第二遮挡板222完全遮蔽住第一出风口121，以及遮蔽住第二出风口122的远离第三出风口123的一半的位置处。
图3至图5是本发明的一些实施例的用于冰箱1的分路送风装置的运动状态示意图。如图3所示，当转盘210转动且传动杆410的凸起411在第一滑槽段431滑动时，通过转盘210带动遮挡板220转动来使遮挡板220调整各个出风口的出风面积，此时挡板300保持打开状态。如图4所示，当转盘210转动且传动杆410的凸起411在第二滑槽段432滑动时，即此时分路送风装置10不需要向储物间室内提供冷量，凸起411可带动传动杆410向其长度方向移动，联动挡板300转动，直至关闭进风口。如图5所示，当转盘210停止转动且传动杆410的凸起411位于第二滑槽段432末端的止档位置时，分路送风装置10停止风量分配工作，且传动杆410联动挡板300完全关闭进风口，以防止冷风由进风口流入使储物间室过冷。
图6是根据本发明一个实施例的冰箱1的示意性结构图，图7是图6中冰箱1的示意性局部结构图，如图6和图7所示，本发明的实施例还提供了一种冰箱1，包括风道组件20和分路送风装置10。具体地，风道组件20包括冷风入口和多个冷风出口，多个冷风出口分别连通冰箱1的多个储物间室，或经由冰箱1的一个储物间室的间室壁上的、处于不同位置处的多个连通口连通该储物间室。分路送风装置10设置于风道组件20内，且分路送风装置10的进风口连通冷风入口，分路送风装置10的多个出风口分别连通风道组件20的多个冷风出口。
该实施例的冰箱1中，风道组件20可向一个储物间室的多个位置处输送冷风时，可根据该储物间室各个位置处的冷量是否充足，控制冷风从相应的风道流入该位置处，以使冷风被合理分配至储物间室不同的位置处，增强 了冰箱1的保鲜性能和运行效率。该分路送风装置10能够实现对风向、风量的调节，使该储物间室内哪里需要冷风就开启那里的冷风出口，不需要冷风就关闭，从而控制冰箱1内温度的恒定性，为冰箱1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1的耗电，节约能源。
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。
