根据本发明的第二方面，本发明还提供一种冰箱，其包括：
箱体，其内限定有用于储存物品的储物间室；
门体，连接在所述箱体的前侧，用于打开和/或关闭所述储物间室；以及
上述任一方案所述的风道组件，设置于所述储物间室的后侧，用于选择 性地向所述储物间室内输送冷却气流。
本发明的风道组件包括限定有气流通道的风道泡沫、可转动地设置在气流通道中的风门、可操作地转动的操作旋钮以及用于将操作旋钮的转动传递至风门的齿轮传动机构。当用户需要调节储物间室内的送风量时，旋转操作旋钮，齿轮传动机构将转动传递至风门，带动风门转动，风门的转动可以改变其覆盖的气流通道的过流断面大小，从而改变气流通道的过流面积，进而改变了经气流通道送往储物间室的气流量大小，实现了调节储物间室温度的目的。由于操作旋钮、齿轮传动机构以及风门的运动方式均为转动，摩擦阻力较小，不会出现卡顿现象，用户操作体验较好。并且，本发明完全通过机械结构实现调温的目的，不需要设置电机、控制程序等，降低了成本。
进一步地，本发明的风道组件还包括至少一个齿轮限位结构，在操作旋钮停止转动后，齿轮限位结构卡设在其中一个齿轮的相邻两个轮齿之间，一方面，可以防止齿轮传动机构在没有外力作用的情况下自动回转，从而确保了风门稳定地保持在所调位置，提高了风门调节的稳定性；另一方面，由于齿轮限位结构的设置可使得齿轮的每个轮齿都相当于风门的一个挡位，实现了风门挡位的微调，提高了风门调节的精度。
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。
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：

图4是根据本发明一个实施例的风门、操作旋钮和齿轮传动机构处于装配状态的示意性结构图；

图7是根据本发明一个实施例的冰箱的示意性结构图。
具体实施方式
本发明首先提供一种用于冰箱的风道组件，该风道组件用于选择性地向冰箱的储物间室输送冷却气流。
图1是根据本发明一个实施例的用于冰箱的风道组件的示意性结构图，图2和图3分别是根据本发明一个实施例的用于冰箱的风道组件在不同方位下的示意性结构分解图。参见图1至图3，本发明的风道组件10包括风道泡沫11、风门12、操作旋钮13和齿轮传动机构14。图4是根据本发明一个实施例的风门、操作旋钮和齿轮传动机构处于装配状态的示意性结构图。
参见图1至图4，风道泡沫11内限定有用于供气流流过的气流通道111，且风道泡沫11上开设有用于连通气流通道111和储物间室的气流出口112，以通过气流出口112将气流通道111内的气流送往储物间室。具体地，气流通道111在风道泡沫11内可沿竖向延伸。气流出口112位于风道泡沫11的前侧。
风门12可转动地设置在气流通道111中，以完全封堵气流通道111或敞开气流通道111的至少部分过流断面。当风门12完全封堵气流通道111时，气流通道111中的流道被完全阻断，气流不会再经气流通道111流向气流出口112。当风门12敞开气流通道111的全部过流断面时，气流通道111的过流面积达到最大，气流量最大；当风门12敞开气流通道111的部分过流断面时，风门12同时对气流通道111的其他部分过流断面进行遮挡，风门12敞开的气流通道111的过流断面越多，气流通道111中的气流量越大。
操作旋钮13配置成可操作地转动。也就是说，用户可转动操作旋钮13，通过操作旋钮13调节风门12的状态。
齿轮传动机构14连接在操作旋钮13和风门12之间，且配置成将操作旋钮13的转动传递至风门12，以通过风门12的转动调节气流通道111的过流面积，从而调节气流通道111的气流量。
本发明的风道组件10包括限定有气流通道111的风道泡沫11、可转动地设置在气流通道111中的风门12、可操作地转动的操作旋钮13以及用于将操作旋钮13的转动传递至风门12的齿轮传动机构14。当用户需要调节风门12的位置时(即用户需要调节储物间室内的温度时)，旋转操作旋钮13，齿轮传动机构14将转动传递至风门12，带动风门12转动，风门12的转动 可以改变其覆盖的气流通道111的过流断面大小，从而改变气流通道111的过流面积，进而改变了经气流通道111送往储物间室的气流量大小，实现了调节储物间室温度的目的。
由于操作旋钮13、齿轮传动机构14以及风门12的运动方式均为转动，摩擦阻力较小，不会出现卡顿现象，用户操作体验较好。并且，本发明完全通过机械结构实现调温的目的，不需要设置电机、控制程序等，降低了成本。
在一些实施例中，风道组件10还包括风道盖板16，风道盖板16设置于风道泡沫11的前侧，以遮挡风道泡沫11。具体地，风道盖板16上开设有用于向储物间室送风的送风口161，送风口161与风道泡沫11的气流出口112前后相对并连通。
图5是根据本发明一个实施例的风道盖板和齿轮传动机构的示意性结构图，图6是图5中部分A的示意性放大图。参见图5和图6，在一些实施例中，风道组件10还包括至少一个齿轮限位结构15，齿轮限位结构15用于在操作旋钮13停止转动后卡设在齿轮传动机构14中的其中一个齿轮的相邻两个轮齿之间，以防止齿轮传动机构14自动回转。也就是说，当用户转动操作旋钮13时，齿轮传动机构14的齿轮相对于齿轮限位结构15运动。当操作旋钮13停止转动后，齿轮限位结构15卡设在其中一个齿轮的相邻两个轮齿之间，一方面，可以防止齿轮传动机构14在没有外力作用的情况下自动回转，从而确保了风门稳定地保持在所调位置，提高了风门12调节的稳定性，从而确保了储物间室的温度稳定在所调的温度区间；另一方面，齿轮限位结构15的设置可使得齿轮的每个轮齿都相当于风门12的一个挡位，实现了风门12挡位的微调，提高了风门12调节的精度，从而使得储物间室内的温度调节更加精细，满足了用户较高的需求。
具体地，齿轮限位结构15设置在齿轮传动机构14的其中一个齿轮的径向外侧。齿轮限位结构15的具体结构形式可以为朝该齿轮的径向内侧凸出的凸起，该凸起可设置在位于该齿轮的径向外侧的环形围板162上，环形围板162优选具有一定的硬度且具有一定的形变能力，以在齿轮转动时允许位于其上的凸起相对于齿轮的轮齿运动、在齿轮静止时允许凸起稳定地卡设在齿轮的相邻两个轮齿之间。
进一步地，齿轮限位结构15的数量可以为两个，两个齿轮限位结构15分布在同一个圆环上，且两个齿轮限位结构15的连线经过该圆环的圆心， 以更加均衡地向齿轮施加限制作用力。
在一些实施例中，齿轮传动机构14为减速齿轮组。也就是说，当操作旋钮13转动时，风门12的转动角度小于操作旋钮13的转动角度，以便于对风门12的转动角度进行更加精细的调节。
进一步地，齿轮限位结构15用于卡设在齿轮传动机构14的末级齿轮的相邻两个轮齿之间。末级齿轮的齿数最多，相当于风门12的挡位数量最多，因此风门12的挡位划分更加精细，角度调节的精度更高。
申请人认识到，风门12从完全封堵气流通道111的关闭状态到完全敞开气流通道111的气流断面的完全打开状态所旋转的角度为90°，即风门12的最大旋转角度为90°。为了便于用户获知风门12当前的挡位，操作旋钮13的旋转角度最大为180°。因此，齿轮传动机构14的减速比可以设置为1:2，能够将风门12的调节精度设置到最大。
具体地，齿轮传动机构14可以为包括两级齿轮的减速齿轮组。
在一些实施例中，操作旋钮13位于风道盖板16的前侧，齿轮传动机构14位于风道盖板16和风道泡沫11之间。由此，仅有需要用户操作的操作旋钮13暴露于外部，便于用户手动操作，其他部件均隐藏在风道组件10的内部，不会影响风道组件10的外观。
在一些实施例中，齿轮传动机构14具体可包括主动齿轮141和从动齿轮142，其中，从动齿轮142为其末级齿轮。主动齿轮141与操作旋钮13同轴连接，以随操作旋钮13同步转动。从动齿轮142与主动齿轮141啮合，且从动齿轮142与风门12同轴连接，以使得风门12随从动齿轮142同步转动。
具体地，主动齿轮141与操作旋钮13之间可通过轴孔和转轴相插接的方式同轴连接，轴孔和转轴形配连接，以使得主动齿轮141与操作旋钮13同步转动。轴孔和转轴可分别形成在操作旋钮13和主动齿轮141的轴心，轴孔和转轴也可以分别形成在主动齿轮141和操作旋钮13的轴心。
具体地，从动齿轮142与风门12之间可通过轴孔和转轴相插接的方式同轴连接，轴孔和转轴形配连接，以使得从动齿轮142与风门12同步转动。轴孔和转轴可分别形成在从动齿轮142与风门12的轴心，轴孔和转轴也可以分别形成在风门12和从动齿轮142的轴心。
在一些实施例中，主动齿轮141和从动齿轮142均通过卡扣与风道盖板 16活动连接。也就是说，主动齿轮141和从动齿轮142均支撑在风道盖板16上，不会从风道盖板16上脱落下来，同时，主动齿轮141和从动齿轮142均可相对于风道盖板16转动。
具体地，卡扣可设置在风道盖板16上，相应地，主动齿轮141和从动齿轮142上设有与卡扣可滑动卡接的配合结构。卡扣也可以形成在主动齿轮141和从动齿轮142上，相应地，风道盖板16上设有与卡扣可滑动卡接的配合结构。例如，主动齿轮141的朝向风道盖板16的一侧可设有卡扣，风道盖板16上设有环形筋，主动齿轮141上的卡扣可滑动地卡接于环形筋。风道盖板16的后向表面设有卡扣，从动齿轮142上开设有环形卡槽，风道盖板16上的卡扣可滑动地卡接于环形卡槽。
进一步地，齿轮限位结构15设置于风道盖板16的后向表面，以便于卡设在主动齿轮141或从动齿轮142的相邻两个轮齿之间。
在一些实施例中，风门12的其中一个表面设有密封件17，密封件17配置成在风门12处于完全封堵气流通道111的关闭状态时与风道泡沫11形成密封，从而避免风门12处于关闭状态时出现漏风现象。
具体地，密封件17可以通过胶黏或其他合适的方式固定在风门12的表面。
在一些实施例中，风道泡沫11包括用于支撑风门12的风门支架113，气流通道111贯穿风门支架113，在风门12处于完全封堵气流通道111的关闭状态时，密封件17与风门支架113过盈配合，从而在风门12与风道泡沫11之间形成良好的密封。
具体地，风门支架113的中部形成贯穿孔，密封件17大致为锥形体，风门12处于完全封堵气流通道111的关闭状态时，密封件17的下部插入风门支架113中部的管穿孔中，并与风门支架113紧密配合。
优选地，密封件17具体可以为密封泡棉、密封胶塞等具有较好变形能力的密封件。
在一些实施例中，风道泡沫11还包括前后排布的风道前泡沫板114和风道后泡沫板115，气流通道111形成在风道前泡沫板114和风道后泡沫板115之间。风道前泡沫板114内侧和风道后泡沫板115内侧的同一高度位置均设有向气流通道111的径向外侧方向凹陷的凹槽116，风门支架113卡装在风道前泡沫板114和风道后泡沫板115的凹槽116内。由此，风门支架113 既不能够在水平方向上发生位移，也不能够在上下方向上发生位移，可以稳定地保持风门支架113，从而确保风门12与风门支架113保持良好的结构配合。
本发明还提供一种冰箱，图7是根据本发明一个实施例的冰箱的示意性结构图。本发明的冰箱1包括箱体20和门体30。箱体20内限定有用于储存物品的储物间室21。门体30连接在箱体20的前侧，用于打开和/或关闭储物间室21。
特别地，冰箱1还包括上述任一实施例所描述的风道组件10，风道组件10设置于储物间室21的后侧，用于选择性地向储物间室21内输送冷却气流。
具体地，操作旋钮13可位于储物间室21内，以便于用户操作。
本发明的冰箱1允许用户通过旋转操作旋钮13来调节储物间室21内的温度范围，操作旋钮13、齿轮传动机构14以及风门12的运动方式均为转动，摩擦阻力较小，用户转动操作旋钮13时不会出现卡顿现象，操作体验较好。并且，本发明的冰箱1完全通过机械结构实现调温的目的，不需要设置电机、控制程序等，降低了成本。
进一步地，本发明的冰箱1还可通过齿轮限位结构15确保风门稳定地保持在所调位置，确保了储物间室21的温度稳定在所调的温度区间。并且，齿轮限位结构15的设置可使得齿轮的每个轮齿都相当于风门12的一个挡位，实现了风门12挡位的微调，提高了风门12调节的精度，从而使得储物间室内的温度调节更加精细，满足了用户较高的需求。由此，储物间室21可以实现冷藏、软冷冻、冷冻等多个功能的自由切换。
本领域技术人员应理解，本发明的冰箱1可以为双开门冰箱，且具有上下两个储物间室，其中，储物间室21可以为处于上部的储物间室。
在另一些实施例中，冰箱1也可以不限为图7所示的冰箱结构，其还可以为单开门冰箱，且仅具有一个储物间室21。
在另一些实施例中，冰箱1也可以不限为图7所示的冰箱结构，其还可以为三门冰箱，且具有上、中、下三个储物间室，其中，储物间室21可以为处于上部或中部的储物间室。
在另一些实施例中，冰箱1也可以不限为图7所示的冰箱结构，其还可以为对开门冰箱，且具有左右两个储物间室，其中，储物间室21可以为处于其中一侧的储物间室。
在另一些实施例中，冰箱1也可以不限为图7所示的冰箱结构，其还可以为十字对开门冰箱，且具有上左、上右、下左、下右四个储物间室，其中，储物间室21可以为处于上部的任一储物间室。
在另一些实施例中，冰箱1也可以不限为图7所示的冰箱结构，其还可以为冷柜或其他各种利用风冷形式制冷的冷藏冷冻装置。
本领域技术人员还应理解，本发明实施例中所称的“上”、“下”、“前”、“后”、“顶”、“底”等用于表示方位或位置关系的用语是以风道组件10和冰箱1的实际使用状态为基准而言的，这些用语仅是为了便于描述和理解本发明的技术方案，而不是指示或暗示所指的装置或不见必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
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。
