技术领域
本发明涉及冷藏冷冻储物领域，特别是涉及一种冰箱。
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向食物的保鲜性能转移了。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，它决定了如何将风输送到储物间室内的合理位置处。在目前市面上的风冷冰箱风路设计中，大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空间，造成现有风道系统的设计比较复杂、结构比较大，且由于现有风道系统结构的限制不能将风输送到预想的位置处。

在本发明的一些进一步的实施例中，每个第一风道的至少末端部分沿着气流的流动方向逐渐扩大，以使每个第一送风口223可为沿水平纵向方向延伸的长条形送风口。每个第一送风口223内也可设置分隔板，使送风口为多个送风小孔。每个第一送风口223可设置于盖板221上。每个第二送风口231也可为沿水平纵向方向延伸的长条形送风口，每个第二送风口231可设置于第二前盖230上。进一步地，后壳210的下端具有向前延伸的回风风道壳213， 回风风道壳213具有一条或多条回风风道2131。回风风道壳213先向前延伸然后向下倾斜延伸，以与箱体100下部的压缩机仓相适应。

在本发明的一些替代性实施例中，盖板221上也可设置多个开口超前的第三送风口，每个第三送风口可与一个相对应的第一风道的始端和末端之间的任一位置处连通，也就是说，一些第一风道不仅可在其末端与储物间室连通，还可在其的其它位置处与储物间室连通。同样地，第二前盖230上可设置有多个开口朝前的第四送风口，每个第四送风口可与一个相对应的第二风道的始端和末端之间的任一位置处连通。
在本发明的一些实施例中，如图5和图6所示，出风装置300还包括风机360，配置成促使气流从进风口进入周壁部310内。风机360优选为离心风机。出风装置300内风机360的设计可进一步使冰箱的结构紧凑，可有效扩大储物空间的体积。在本发明的一些优选的实施例中，出风装置300还包括调节部350，相对于周壁部310可转动地设置于周壁部310内，以在不同的运动位置处，对每个第一出风口311进行完全遮蔽、部分遮蔽或完全暴露，从而调整多个第一出风口311各自的出风面积。调节部350的设置能够对储物空间的送风量进行统一控制，可合理分配送风量，提高冰箱的制冷效果，以及保鲜效果。
在本发明的一些实施例中，周壁部310优先呈筒状，其可与第一轴向端部320和第二轴向端部330中的一个一体成型，另一个可卡接于周壁部310。周壁部310、第一轴向端部320和第二轴向端部330的整体结构也可被称为出风装置300的壳体。多个第二出风口321沿第一轴向端部320的周向方向依次设置，优选为均匀地依次设置。当然，多个第二出风口321也沿第一轴向端部320的周向方向也可为不均匀地设置。进一步地，第一轴向端部320包括中央部和处于中央部外侧的外围部，为了便于出风，每个第二出风口321设置于外围部。风机360可安装于中央部。优选地，每个第二出风口321可呈沿第一轴向端部320的周向方向延伸的环形段状。
在本发明的一些实施例中，周壁部310的处于每两个相邻的第二出风口321之间的周壁区段上设置有一个第一出风口311。这样设置可充分利用进入周壁部310内的气流，可保证进入第二出风口321的气流量，也可保证出风顺畅，防止进入第一出风口311和第二出风口321的气流产生严重的干涉，防止如较大噪音等不良现象产生。
为了使每个第二出风口321尽可能地进行轴向出风，即每个第二出风口321配置成轴向出风，外围部可设置成包括平板部和至少一个引导部322。平板部上设置有至少一个第二出风口321。进一步地，在一些实施例中，每个引导部322从一个第二出风口321的临近周壁部310的边缘处向第一轴向端部320内侧且朝周壁部310的轴线倾斜地延伸出。引导部322可呈板状，也可被称为引导板。进一步地，每个引导部322的两端也可设置引导遮挡板。在另一些实施例中，每个引导部322从一个第二出风口321的远离周壁部310的边缘处向第一轴向端部320外侧且朝远离周壁部310的轴线的方向倾斜地延伸出。引导部322可呈板状，也可被称为引导板。进一步地，每个引导部322的两端也可设置引导遮挡板。引导部322的倾斜角度可为30°至60°，优选为40°、43°、45°、47°、50°等。中央部可呈平板状。在一些替代性实施例中，引导部322也可仅为引导气流流动的引导面，以简化第一轴向端部320的结构或便于第一轴向端部320的设计。
在本发明的一些实施例中，调节部350可包括一个或多个沿第一轴向端部320的周向方向间隔设置的遮挡部351，以及至少一个流通部352。遮挡部351和流通部352沿第一轴向端部320的周向方向依次设置，且一个或多个遮挡部351与至少一个流通部352围成一筒状结构。而且，调节部350设置于周壁部310的内侧，在转动到不同的转动位置处，使一个或多个遮挡部351对每个第一出风口311进行完全遮蔽、部分遮蔽或完全暴露，使气流经由至少一个流通部352进入被部分遮蔽或完全暴露的第一出风口311。
具体地，遮挡部351可为遮挡片，每两个相邻的遮挡片之间的间隔、缺口或孔洞可为流通部352，特别地，当遮挡部351只有一个时，则相应的流通部352也只有一个。例如，调节部350可包括基部，设置于基部上的遮挡片。再例如，调节部350可包括一筒状件，且筒状件上开设有多个流通部352。筒状件的两端均可设置基部，以提高强度。进一步可选地，基部可用于转动地安装于第一轴向端部320或第二轴向端部330。例如，第一轴向端部320或第二轴向端部330的内表面上设置有环形凹槽，基部上可设置有与环形凹槽对应的环形凸起，以插入环形凹槽便于转动。还可选地，基部可转动地安装于周壁部310的一端，当周壁部310与第一轴向端部320一体成型时，基部可转动地安装于周壁部310的靠近第二轴向端部330的一端。
在本发明的一些实施例中，出风装置300还可包括电机370和传动机构。电机370可设置于周壁部310的径向外侧。传动机构配置成将电机370输出的旋转运动传递至调节部350。例如，传动机构可优选为齿轮传动机构，调节部350的基部上设置有齿圈380(齿圈380可与基部一体成型)，电机370的输出端可安装有齿轮，齿轮与齿圈380啮合，从而可使电机 370带动齿圈380旋转，进而带动调节部350转动。进一步地，周壁部310的外侧可设置有电机容纳部，以容装电机370。
在本发明的一些实具体地施例中，出风口二、出风口一和出风口三沿第一轴向端部320的周向方向且可沿顺时针方向(以观察者从第一轴向端部320看向第二轴向端部330的视线为基准，即前后方向观察的视线为基准)依次间隔设置。且，出风口二与另外两个第一出风口311之间的距离均可为一个第一出风口311的长度。调节部350中，遮挡部351和流通部352的数量均为三个。三个遮挡部351分别为第一遮挡部、第二遮挡部和第三遮挡部。三个流通部352分别为第一流通部、第二流通部和第三流通部。遮挡部351和流通部352沿第一轴向端部320的周向方向且可沿逆时针方向依次间隔设置。第一遮挡部和第二遮挡部均配置成允许其完全遮蔽一个大小的第一出风口311的区域。第三遮挡部配置成允许其至少完全遮蔽两个大小的第一出风口311的区域，如第三遮挡部可遮蔽两个大小的第一出风口311的区域。第一遮挡部和第二遮挡部之间的流通部为第一流通部，配置成完全暴露一个大小的第一出风口311的区域。第二遮挡部和第三遮挡部之间的流通部为第二流通部，配置成完全暴露一个大小的第一出风口311的区域。第三遮挡部和第一遮挡部之间的流通部为第三流通部。在工作时，调节部350转动可使不同的第一出风口311处于打开状态，例如当第一遮挡部遮挡出风口一时，出风口二和出风口三可处于打开状态；再例如，当第二遮挡部遮挡出风口一时，出风口二和出风口三均可处于关闭状态。
在本发明的一些替代性实施例中，出风口一与另外两个第一出风口311之间的距离均可为一个第一出风口311的长度的1/7至1/10。调节部350中，遮挡部351和流通部352的数量均为两个。两个遮挡部351分别为第一遮挡部、第二遮挡部。两个流通部352分别为第一流通部、第二流通部。遮挡部351和流通部352沿第一轴向端部320的周向方向且可沿顺时针方向依次间隔设置。第一遮挡部配置成允许其完全遮蔽一个第一出风口311。第二遮挡部配置成允许其至少完全遮蔽两个第一出风口311，如第二遮挡部可遮蔽三个第一出风口311以及每两个第一出风口311之间的周壁部310的连接段。第一流通部配置成完全暴露一个第一出风口311。第二流通部配置成可完全暴露三个第一出风口311。在工作时，调节部350转动可使不同的第一出风口311处于打开状态，例如当第一遮挡部遮挡出风口一时，出风口二和出风口三可处于打开状态；再例如，当第一流通部导通出风口一时，出风口二和出风口三均可处于关闭状态。
在本发明的一些实施例中，多个第一出风口311中任意两个第一出风口311的大小可相等也可不等。多个第二出风口321中任意两个第二出风口321的大小可相等也可不等。
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。
