Description

冰箱 技术领域
本发明涉及冷冻冷藏技术领域，特别是涉及一种冰箱。
背景技术
风冷冰箱能够保鲜食品，延长食品储存时间，提高食品食用安全性，是一种必备的家用电器。然而，在现有的风冷冰箱中，送风风道一般设置在冰箱储物间室的后部，冷气吹出后下沉，导致储物间室前部温度较热，后部温度冷，温度不均匀。储物间室前部更靠近门体，容易漏热，导致储物间室前部的温度更高，对保存食品不利。特别地，对于需要快速制冷的物品，如刚买回家的饮料或者西瓜等，现有的冰箱需要很长的时间才能够使这些物品达到用户想要的低温，不能够满足用户及时使用这些物品。
发明内容
本发明的目的旨在克服现有冰箱的至少一个缺陷，提供一种新颖的冰箱，其能够解决如何使放入其内的某些物品快速地得到冷却的技术问题，可使放入其内的某些物品快速达到用户想要的冷却温度。
为此，本发明提供了一种冰箱，其包括储物间室和用于输送冷风的制冷风道。特别地，该冰箱还包括：
顶部风道，设置于储物间室的顶壁，其与制冷风道连通，以接收来自制冷风道的冷风；
导风管，具有与顶部风道连通的进风端和向储物间室内送风的送风端，且导风管从其进风端沿水平方向延伸预设长度后向下弯转至其送风端，以形成开口朝下的送风口；和
第一送风装置，配置成促使气流从顶部风道进入导风管，以使从制冷风道中流入顶部风道的冷风经由导风管聚集地向下吹送。
可选地，该冰箱还包括第二送风装置，配置成促使冷风进入制冷风道。
可选地，导风管的进风端的进风口连通且连接至顶部风道的出风口，且第一送风装置设置在顶部风道和/或导风管内；或
第一送风装置的进风口连通且连接至顶部风道的出风口，第一送风装置的送风口连通且连接至导风管的进风端的进风口。
可选地，第一送风装置为离心风机或设置于顶部风道的出风口处的离心叶轮。
可选地，第一送风装置配置成将流入顶部风道的冷风从其上方吸入，并将该冷风中的至少部分或全部沿水平方向吹送到导风管中。
可选地，顶部风道沿纵向方向延伸地设置于储物间室的顶部的一个沿纵向方向延伸的角落内，其后端端面形成有与制冷风道连通的进风口，其前端形成有向导风管送风的出风口。
可选地，导风管的水平管段部分沿水平横向方向延伸；导风管的送风口朝向其竖直下方，且处于储物间室的横向中央位置处。
可选地，制冷风道设置于储物间室的后壁，具有至少一个与储物间室连通的第一出风口，以及与顶部风道连通的第二出风口。
可选地，制冷风道包括总冷风道，以及与总冷风道连通的第一支路和第二支路；至少一个第一出风口设置在第一支路上；第二出风口设置在第二支路上。
可选地，该冰箱还包括：风道通断装置，配置成受控地关断或导通第一支路和/或第二支路。
本发明的冰箱由于具有顶部风道、导风管和第一送风装置，其可使来自制冷风道的冷风聚集地向下吹送，以集中向储物间室内导风管的送风口下方的区域送风，即可对储物间室内局部区域快速降温，从而可使放置于导风管的送风口下方的物品快速地得到冷却。
进一步地，本发明的冰箱由于可将其内所有的冷量集中吹向某一特定的区域，使得放入该区域内的食物(如饮料、水、块肉等)快速的进行制冷，对于食物的存储及保鲜等具有良好的效果，也能够满足用户及时使用的要求。

图1是根据本发明一个实施例的冰箱100的示意性结构图。如图1所示，本发明实施例提供了一种冰箱100。该冰箱100一般性可包括用于储存食物的储物间室11、用于向该储物间室11提供和/或输送冷风的制冷风道20和封闭该储物间室11的门体14。特别地，该冰箱100还可 包括顶部风道30、导风管40和第一送风装置50。顶部风道30可设置于储物间室11的顶壁，其与制冷风道20连通，以接收来自制冷风道20的冷风。导风管40具有与顶部风道30连通的进风端和向储物间室11内送风的送风端。优选地，导风管40从其进风端沿水平方向延伸预设长度后向下弯转至其送风端，以形成开口朝下的送风口。第一送风装置50配置成促使气流从顶部风道30进入导风管40，以使从制冷风道20中流入顶部风道30的冷风经由导风管40聚集地向下吹送，从而使导风管40的送风口下方的区域内的物品92快速受冷。
在本发明的一些进一步实施例中，导风管40的进风端的进风口连通且连接至顶部风道30的出风口，且第一送风装置50设置在顶部风道30和/或导风管40内。例如，第一送风装置50可为设置于顶部风道30的出风口处的离心叶轮或轴流风机。在本发明的另一些进一步实施例中，第一送风装置50的进风口连通且连接至顶部风道30的出风口，第一送风装置50的送风口连通且连接至导风管40的进风端的进风口。例如，第一送风装置50可为离心风机。
在本发明的一些实施例中，制冷风道20不仅可以向顶部风道30内提供冷风，也可直接向储物间室11内提供冷风。具体地，制冷风道20可设置于储物间室11的后壁，具有至少一个与储物间室连通的第一出风口221，以及与顶部风道30连通的第二出风口231。
图2是根据本发明一个实施例的冰箱100的示意性左视图，如图2所示，顶部风道30沿纵向方向延伸，其后端端面形成有与制冷风道20连通的进风口，其前端形成有向导风管40送风的出风口。例如，冰箱100可包括顶部风道盖板，安装于储物间室11顶壁的内表面，以形成上述顶部风道30。顶部风道盖板可包括盖板部和位于盖板部前端的向下突出的凸腹板部，第一送风装置50可设置在凸腹板内。为了便于储物间室11内空间的合理布置，顶部风道30可设置在该储物间室11顶部的一个沿纵向方向延伸的角落里。
进一步地，如图1所示，导风管40的水平管段部分沿水平横向方向延伸。导风管40的送风口朝向其竖直下方，且可处于储物间室11的横向中央位置处，以方便的用户放置需要快速冷却的物品。在该实施例中，第一送风装置50可为离心风机或离心叶轮，配置成将流入顶部风道30的冷风从其上方吸入，并将该冷风中的至少部分或全部沿水平方向吹送到导风管40中。
在本发明的一些实施例中冰箱100还可包括第二送风装置60，配置成促使冷风进入制冷风道20，第二送风装置60可为冰箱100的储物间室11内的部分或全部气体流出该储物间室11且被冷却后流入该制冷风道20提供动力。例如，本发明实施例中的冰箱100还可包括冷却室13、冷却器70和回风风道。冷却室13形成有通向制冷风道20的送风口。冷却器70可为压缩制冷系统的蒸发器，设置在冷却室13内，以对流经其的气体进行冷却。回风风道连通储物间室 11的下部空间与冷却室13。第二送风装置60可设置在冷却室13的送风口处，配置成促使储物间室11内的部分或全部气体经由回风风道进入冷却室13且被冷却器70冷却后进入制冷风道20。
在本发明的一些实施例中，为了便于集中送风，如图3所示，制冷风道20包括总冷风道21，以及与总冷风道21连通的第一支路22和第二支路23。至少一个第一出风口221设置在第一支路22上，第二出风口231设置在第二支路23上。冷却室13的送风口可与总冷风道21连通。优选地，本发明实施例中的冰箱100还可包括风道通断装置，配置成受控地关断或导通第一支路22和/或第二支路23。具体地，风道通断装置可包括第一风门81和第二风门82，第一风门81可设置在总冷风道21的进风口处，以控制总冷风道21的通断。第二风门82可设置在第一支路22和第二支路23的进风口处，以在控制第一支路22导通时，关断第二支路23；在控制第二支路23导通时，关断第一支路22。例如在集中送风时，可同时开启第一送风装置50和第二送风装置60，开启第一风门81，导通第二支路23，以使冷风全部从导风管40的送风口向下吹送。
在本发明的一些实施例中，为了便于物品的取放，该实施例中的冰箱100还可包括抽屉90，其内可放置物品92，如牛肉、西瓜和饮料等。该抽屉90可操作地向内插入储物间室11或从储物间室11向外拉出，即该抽屉90安装于储物间室11内。可选地，抽屉90的后壁下部均具有通风孔，以便于从导风管40的送风口流出的气流与抽屉90内的物品换热后从抽屉90上的通风孔流出抽屉90，以进入回风风道参与循环。
在本发明的一些实施例中，如图2所示，冰箱100还可包括另一储物间室12，其可设置于储物间室11的下方。例如，储物间室11可为冷藏室，另一储物间室12可为冷冻室。进一步地，在储物间室11和另一储物间室12之间也可设置速冻室。
本发明实施例中的冷却室13可形成在另一储物间室12的后方。冰箱100内还具有连通冷却室13的送风口和另一储物间室12的另一制冷风道，以及连通另一储物间室12和冷却室13的另一回风风道。在本发明的一些替代性实施方式中，制冷风道20和回风风道均与另一储物间室12，即与冷冻室，连通；而不连通冷却室13，以利用冷冻室内的冷量。
在本发明的一些实施例中，冰箱100还可包括可动式送风机罩83。可动式送风机罩83设置在冷却室13的送风口的外侧，且配置成在封闭冷却室13的送风口时提供有供冷却气体流向制冷风道20的开口部；也就是说，当可动式送风机罩83封闭冷却室13的送风口时，可截断与另一储物间室12连通的另一制冷风道，使制冷风道20保持畅通。
本发明实施例的冰箱100在工作时可具有多种工作模式，如图1至图3所示，图中箭头可 表示气流的流向，多种工作模式可包括如下工作模式：储物间室11单独工作模式：可动式送风机罩83处于关闭状态，第一风门81处于打开状态，第二风门82导通第一支路22，第二送风装置60工作，而第一送风装置50不工作，可使储物间室11单独工作。另一储物间室12单独工作模式：可动式送风机罩83处于打开状态，第一风门81处于关闭状态，第二送风装置60工作，而第一送风装置50不工作，可使另一储物间室12单独工作。共同工作模式：可动式送风机罩83处于打开状态，第一风门81处于打开状态，第二风门82导通第一支路22，第二送风装置60工作，而第一送风装置50不工作，可使两个储物间室11共同工作。精确制冷模式：可动式送风机罩83处于关闭状态，第一风门81处于打开状态，第二风门82导通第二支路23，第一送风装置50和第二送风装置60均工作，可使储物间室11内一特定区域精确制冷。为了防止储物间室11内其他区域和另一储物间室12内温度回升过高，精确制冷模式工作一定的时间后自动退出该模式。
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。
