Description

风冷冰箱 技术领域
本发明涉及冷冻冷藏技术领域，特别是涉及一种风冷冰箱。
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，目前市场上风冷冰箱在化霜时，随着加热丝温度的升高，热空气直接从风道口对流到冷冻间室，导致食物表面温度升高，加速食物变质。同时，冷冻间室温度升高，增加了下一次的制冷时间，加大耗电量。为了防止热空气直接进入储物间室，通常在冷却室出风口处的轴流风机上设置一升降式遮蔽罩，需要化霜遮蔽时把罩子垂直罩住风机以及冷却室出风口，送风时垂直打开罩子，露出轴流风机冷却室出风口，这样设计存在的问题是占用空间太大，罩子容易冻结失效。具体地，现有的风机遮蔽技术体积大，化霜时，风机上的化霜水容易流到运动部件和固定件的间隙之间，不容易排出，易冻结。

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1是根据本发明一个实施例的风冷冰箱的示意性结构图；
图2是图1所示风冷冰箱中第一风道部的示意性结构图；
图3是图2所示第一风道部的示意性爆炸图；
图4是图1所示风冷冰箱中风门遮蔽装置的示意性结构图；
图5是图4所示风门遮蔽装置的示意性爆炸图；
图6是图4所示风门遮蔽装置的另一视角的示意性爆炸图。
具体实施方式
图1是根据本发明一个实施例的风冷冰箱的示意性结构图，其中示出方向可为从风冷冰箱的后侧向前示出，图中箭头可表示气流流向。如图1所示 并参考图2至图6，本发明实施例提供了一种风冷冰箱100，包括箱体200，箱体200内具有冷却室102、至少一个储物间室101、连通冷却室和至少一个储物间室的风道组件(300、400)，以及风门遮蔽装置500。风道组件可具有进风口104朝后的容纳腔105，容纳腔的周壁上设置有多个送风连通孔106。冷却室内的气体经由多个送风连通孔进入至少一个储物间室。
风门遮蔽装置500可包括遮挡件520；遮挡件520具有多个挡风板521。遮挡件520可转动地设置于容纳腔，以具有使多个挡风板521完全遮蔽所有送风连通孔的遮蔽位置，进而在风冷冰箱化霜时阻碍冷却室内的气体经多个送风连通孔进入至少一个储物间室。具体地，在风冷冰箱除霜时可使挡风板521转动到封闭出送风连通孔的遮蔽位置；在风冷冰箱正常送风时，可使挡风板521转动到完全暴露所有送风连通孔的正常位置。本发明实施例利用可转动设置的挡风板521，可使挡风板521转动到封闭出送风连通孔的遮蔽位置，也可转动到完全暴露送风连通孔的正常位置以实现正常送风。采用旋转式机构，缩小风门遮蔽装置500的体积，结构简单紧凑且控制方便。
进一步地，容纳腔的侧壁的底部具有向后且向下倾斜设置的导水槽381，且风道组件具有连通风道组件后侧和导水槽381后端的出水孔382，以使容纳腔内的水经由导水槽381和出水孔382流出风道组件。容纳腔的侧壁的底部也可从前向后且向下倾斜设置，以利于进入容纳腔的水在容纳腔内聚集，便于排出容纳腔内以及风门遮蔽装置500上的水，防止风门遮蔽装置500冻结失效。
在本发明的一些实施例中，如图4至图6所示，风门遮蔽装置500还可包括基座510。基座510可竖向设置。遮挡件520还可具有安装于基座510的转盘部522，多个挡风板521从转盘部522向转盘部522的一侧延伸出，且沿转盘部522的周向方向间隔设置。

为了防止运动到容纳腔的化霜水在容纳腔内聚集，以及进入风门遮蔽装置500中的各个部件之间聚集，冻结风门遮蔽装置500，本发明的转盘部522的朝向底座板511的一侧设置有环形筋523，可与底座板511接触抵靠。底座板511的边缘的朝向转盘部522的一侧为斜面，以使转盘部522与底座板511之间呈现向外张口结构。
在本发明的一些实施例中，为了便于遮挡件520的转动，风门遮蔽装置500还可包括电机541、主动齿轮542和从动齿轮543。电机541设置于遮挡件520的径向外侧，且安装于基座510。主动齿轮542安装于电机541的输出轴。从动齿轮543可安装于转盘部522或与转盘部522一体成型，且与主动齿轮542啮合。电机541设置于遮挡件520的径向外侧可显著降低风门遮蔽装置500的整体厚度，特别适用于冰箱。在一些替代性实施例中，也可采用其他传动形式，如带传动、链传动、齿轮齿条转动等，也可将遮挡件520直接安装于电机541的输出轴。
在本发明的一些优选的实施例中，从动齿轮543为齿圈，设置于转盘部522的背向挡风板521的一侧。底盖513的内侧设置有第二位置挡板514和第三位置挡板515。齿圈设置于第二位置挡板514的径向外侧，设置于第三位置挡板515的径向内侧。第一位置挡板512、第二位置挡板514和第三位置挡板515可根据需求决定其沿基座510的周向方向的长度。
进一步地，第二位置挡板514具有缺口；转盘部522的背向挡风板521的一侧还设置有凸块523，设置于缺口内，以限定转盘部522的转动范围。
在本发明的一些实施例中，基座510还包括电机安装部550和跨越板560；且跨越板560包括：第一让位板561，从底座板511的边缘向远离底座板511的方向延伸出；第二让位板562，与第一让位板平行设置，且处于挡风板521的径向外侧；连接板563，连接第一让位板和第二让位板，且允许一个或多个挡风板521可进入第一让位板和第二让位板之间。电机安装部550设置于第二让位板的背离第一让位板的一侧；电机541安装于电机安装部550；底盖513还罩设于电机安装部550。

在本发明的一些实施例中，风道组件可包括第一风道部300。容纳腔设置于第一风道部300的上部；第一风道部300的后表面中部和/或下部向前凹陷，且第一风道部300的后侧为冷却室；第一风道部300的前侧为一个或多个储物间室。容纳腔内的水可直接进入冷却室，并且随着冷却室底部设置的化霜水排出机构排出冷却室。风门遮蔽装置500的离心风轮590可从进风口吸入气流，并促使气流从其周向和/或径向进入每个送风连通孔。这样设置可使风冷冰箱的结构紧凑，布局合理，安装装配方便。
在本发明的一些实施例中，如图2和图3所示，第一风道部300可包括后盖板310、中间板320和前盖板330。后盖板310具有背板311，以及从背板311延伸出的腔体限定板312。背板311的上部开设有进风口；腔体限定板312限定出容纳腔、多个送风连通孔，以及分别与多个送风连通孔的送风风道，送风风道包括至少一个第一送风风道。中间板320设置于背板311的前侧，且与腔体限定板312接触抵靠。前盖板330罩设于后盖板310，且前盖板330具有处于中间板320前侧的前板，以及形成于前板上的多个送风结构。中间板320被布置成使得每个第一送风风道经由其连通一个或多个送风结构。具体地，中间板320上可设置有缺口或孔洞等结构，以使第一送风风道内的气流进入相应的送风结构。送风结构可为送风口、送风短管等。
