具体实施方式
图1是根据本发明一个实施例的冰箱10的示意性结构图，图2是根据本发明一个实施例的冰箱10的部分结构的示意性结构图。
冰箱10一般性地可包括内胆320和引风风道总成210。图2中示出了装配有引风风道总成210的内胆320。内胆320用于与冰箱10的箱壳装配，以形成箱体110。
图3是根据本发明一个实施例的冰箱10的内胆320的示意性结构图。
其中，内胆320限定出风道安装区328，用于安装引风风道总成210。例如，图8中，内胆320的内部还限定出位于风道安装区328一侧、并用于储物的低温储存区322。引风风道总成210可以将来自该内胆320外部的换热气流导引至低温储存区322，以调节低温储存区322的温度。
引风风道总成210的外形与风道安装区328的外形相适配，配置成通过卡入风道安装区328，使引风风道总成210的外表面与风道安装区328的内表面相互抵压，以实现固定装配。
本实施例的冰箱10，改进了冰箱10的引风风道总成210的安装方式。通过对引风风道总成210的外形进行改进，使其与内胆320的风道安装区328的外形相适配，可使引风风道总成210通过卡入风道安装区328，使引风风道总成210的外表面与风道安装区328的内表面相互抵压，以实现固定装配，因此，无需再额外设置卡扣结构，有利于简化装配结构，降低安装难度。
图4是根据本发明一个实施例的冰箱10的引风风道总成210的示意性结构图。
引风风道总成210具有引风风道壳体211，其内部限定出引风风道。引风风道总成210的外表面即引风风道壳体211的外表面。
在一些可选的实施例中，风道安装区328的内表面通过与引风风道总成210的外表面相互抵压向引风风道总成210施加竖直向上的合力，以平衡其重力。
例如，风道安装区328的内表面与引风风道总成210的外表面之间可以形成多个抵压面，多 个抵压面共同作用，形成竖直向上的合力。
在一些实施例中，风道安装区328限定在内胆320的两个相对设置的侧壁之间。引风风道总成210相对于风道安装区328具有横向过盈量，以利用横向过盈量相互抵压，使引风风道总成210受到的合力平衡其重力。
利用横向过盈量，引风风道总成210的横向一端与风道安装区328的横向一侧壁相互抵压，而引风风道总成210的横向另一端与风道安装区328的横向另一侧壁相互抵压，使得风道安装区328的两个侧壁向引风风道总成210施加竖直向上的合力，以平衡其重力。
图5是图4所示的冰箱10的引风风道总成210的示意性主视图，图6是图4所示的冰箱10的引风风道总成210的示意性俯视图。
在一些可选的实施例中，引风风道总成210的横向一端设置有弹性件270，且引风风道总成210的横向另一端形成有与风道安装区328卡接配合的卡接面219。
卡接面219配置成通过与风道安装区328的横向一端卡接配合，使弹性件270与风道安装区328的横向另一端相互挤压，从而实现固定装配。
由于弹性件270受挤压可发生形变，通过在引风风道总成210的横向一端设置弹性件270，在安装引风风道总成210时，可先将弹性件270抵靠于风道安装区328的横向一侧壁，然后将引风风道总成210的横向另一端卡入风道安装区328的横向另一侧壁。在横向过盈量的作用下，在引风风道总成210的横向另一端卡入风道安装区328的的横向另一侧壁的过程中，风道安装区328的与卡接面219对应装配的侧壁向引风风道总成210的卡接面219施加横向挤压力，从而使弹性件270受挤压产生形变，进而使得引风风道总成210可以完全卡入风道安装区328。
弹性件270可以由用于密封接口的弹性密封材料制成。由于弹性密封件的设置是本领域技术人员所悉知的，在此不做赘述。
在一些可选的实施例中，卡接面219包括向后且向引风风道总成210内侧倾斜延伸的导向斜面219a。
风道安装区328与卡接面219卡接配合的横向一端形成向后且向内胆320内侧倾斜延伸的胆部斜面328a。胆部斜面328a与导向斜面219a相互平行设置，以允许导向斜面219a通过向后移动与胆部斜面328a卡接，从而使胆部斜面328a向导向斜面219a提供横向挤压力。
在导向斜面219a与胆部斜面328a的相互作用下，可以向引风风道总成210提供定向移动的导向力，使引风风道总成210顺畅地卡入风道安装区328，并挤压弹性件270，从而固定在风道安装区328内。
其中，“横”“纵”“前”“后”“内”“外”等方位用词均是相对于各个部件的实际使用状态而 言的。“横向”大致平行于冰箱10箱体110的横向延伸方向，“前后方向”大致平行于冰箱10箱体110的进深方向。例如，当导向斜面219a形成在引风风道总成210的右端时，其向后且向左延伸，相应地，胆部斜面328a向后且向左延伸。
导向斜面219a与胆部斜面328a相对于内胆320的进深方向的夹角分别为10～20°，例如可以为12°，15°或者18°。内胆320的进深方向是相对于内胆320装配于冰箱10时的实际使用状态而言的，其平行于冰箱10箱体110的进深方向。
基于上述结构，导向斜面219a与胆部斜面328a之间通过相互作用，既能产生导向力，使引风风道总成210顺畅地卡入风道安装区328，又能使风道安装区328向引风风道总成210整体提供适当的挤压力。
当安装者向引风风道总成210施加垂直作用力(沿内胆320的进深方向)时，胆部斜面328a配合导向斜面219a将安装者所施加的垂直作用力转化为内胆320向引风风道总成210的横向挤压力，使内胆320挤压引风风道总成210，一方面使得引风风道总成210可以紧密地卡在内胆320上，另一方面使得引风风道总成210的弹性件270受到充分挤压，从而使引风风道总成210与内胆320之间密封严密，不易漏风漏冷。
图7是根据本发明一个实施例的冰箱10的内胆320的另一示意性结构图。在一些可选的实施例中，风道安装区328与弹性件270相抵压的横向一端开设有引风口326。该引风口326用于与引风风道总成210的进风口218对接，使得来自内胆320外部的换热气流流入引风风道总成210内。
弹性件270呈环状，至少部分地凸出于引风风道总成210的横向端部且避让引风口326和进风口218，以与引风口326的外周缘相互挤压，从而避免遮蔽引风口326和进风口218，保证风路顺畅。
图8是根据本发明另一实施例的冰箱10的部分结构的示意性结构图，图中示出了装配有引风风道总成210和导风风道总成220的内胆320。图9是根据本发明一个实施例的冰箱10的引风风道总成210和导风风道总成220的示意性装配图。引风风道总成210和导风风道总成220可以形成分体式风道组件200。
在一些进一步的实施例中，引风风道总成210具有进风口218和送风口216以及形成于进风口218和送风口216之间的引风风道。进风口218与引风口326对接，以允许来自引风口326的气流流入引风风道，并流出送风口216。送风口216可以连通低温储存区322，并将换热气流吹入低温储存区322。
进风口218的外周缘至少部分地伸入引风口326内，弹性件270环绕设置于进风口218的外 周缘。当进风口218的外周缘伸入引风口326内时，弹性件270受挤压发生形变，从而密封引风口326与进风口218之间的间隙，防止漏风漏冷。
在一些可选的实施例中，上述横向过盈量可以为1～5mm，例如可以为2mm，3mm或者4mm。横向过盈量是指引风风道总成210的横向尺寸与风道安装区328的横向尺寸之间的差值。例如，可以基于胆部斜面328a的前端与内胆320的另一侧壁上等高等深位置处的特定部位之间的间距确定风道安装区328的横向尺寸，相应地，可以基于导向斜面219a的前端与引风风道总成210的横向另一端部上等高等深位置处的特定部位之间的间距确定风道安装区328的横向尺寸。需要说明的是，在一些实施例中，弹性件270不介入横向过盈量的计算过程。
通过使引风风道总成210相对于风道安装区328具有横向过盈量，以利用横向过盈量相互抵压，使引风风道总成210受到的合力平衡其重力，可以提高冰箱10的引风风道总成210相对于内胆320的装配稳定性，从而提高冰箱10的风路稳定性。
基于上述横向过盈量，并在胆部斜面328a与导向斜面219a的导向配合作用下，内胆320与引风风道总成210之间可以进行紧密地装配，且装配方式简洁、高效、效果稳固。
图10是根据本发明一个实施例的冰箱10的引风风道总成210的示意性结构图，图中示出了引风对接口212。图11是根据本发明一个实施例的冰箱10的导风风道总成220的示意性结构图，图中示出了导风对接口222。
在一些可选的实施例中，冰箱10还可以进一步地包括导风风道总成220，其限定出导风风道以及与导风风道连通的导风对接口222。
引风风道总成210还具有连通引风风道的引风对接口212，引风风道总成210和导风风道总成220相互压合对接使导风对接口222与引风对接口212连通，从而贯通引风风道和导风风道。利用导风风道总成220和引风风道总成210相互配合，可以提高导风效果和送风效果。
图12是根据本发明一个实施例的冰箱10的引风风道总成110和导风风道总成220的沿纵向剖切的示意性剖视图，剖切方向可以平行于分体式风道组件200的前后延伸方向，图中示出了引风风道总成210和导风风道总成220的相互压合对接结构。
在一些可选的实施例中，引风风道总成210具有伸向导风风道总成220的第一压合面214，导风风道总成220具有伸向引风风道总成210且与第一压合面214相互导向并压合对接的第二压合面224。引风对接口212开设于第一压合面214上，导风对接口222开设于第二压合面224上。
其中，第一压合面214与第二压合面224相互导向并压合对接是指，第一压合面214导引第二压合面224朝向第一压合面214移动，并在第二压合面224移动至与第一压合面214相抵时使第二压合面224制动，并使二者相互压合对接。
通过在引风风道总成210上设置第一压合面214，并在导风风道总成220上设置第二压合面224，且在第一压合面214上和第二压合面224上分别开设引风对接口212和导风对接口222，可使分体式风道组件200的各个风道总成之间通过相对移动实现定位并连接，这有利于简化连接过程。
在一些可选的实施例中，第一压合面214和第二压合面224可以形成相互压合对接的多组压合面。多组压合面可以在不同平面内进行压合对接，或者可以在不同位置处进行压合对接，从而进行多角度地定位，提高压合对接的精度。引风对接口212和导风对接口222可以设置在任一组相互压合对接的压合面内。
当然，在另一些实施例中，第一压合面214和第二压合面224可以形成相互压合对接的一组压合面。
在一些可选的实施例中，第一压合面214包括第一倾斜端面214a，第一倾斜端面214a内开设有引风对接口212。第二压合面224包括第二倾斜端面224a，第二倾斜端面224a内开设有导风对接口222。
第一倾斜端面214a与第二倾斜端面224a相互平行地倾斜设置，以允许引风风道总成210和导风风道总成220通过相对移动使第一倾斜端面214a和第二倾斜端面224a相互压合对接。
通过使第一倾斜端面214a与第二倾斜端面224a相互平行地倾斜设置，当某一风道总成先行固定在内胆时，另一风道总成可以沿着内胆的进深方向朝向固定的风道总成移动，并使两个倾斜端面在移动过程中相互压合对接，这种对接方式十分适用于具有前向开口、且具有有限容积的内胆，可以大幅降低两个风道总成之间连接过程的操作难度。
第一倾斜端面214a与第二倾斜端面224a的倾斜方向可以根据风道的延伸方向以及各个风道总成的相对位置进行设置。例如，第一倾斜端面214a与第二倾斜端面224a可以分别向后且向上地倾斜设置，或者可以分别向左且向上地倾斜设置，或者可以分别向左且向下地倾斜设置，或者可以分别向右且向上地倾斜设置，或者可以分别向右且向下地倾斜设置，但不限于此。
在一些可选的实施例中，第一倾斜端面214a位于引风风道总成210的底部，第二倾斜端面224a位于导风风道总成220的顶部，且分别向后且向下地倾斜设置，以允许引风风道总成210和导风风道总成220通过沿前后方向相对移动使第一倾斜端面214a和第二倾斜端面224a相互压合对接。
通过使第一倾斜端面214a与第二倾斜端面224a分别向后且向下地倾斜设置，当某一风道总成先行固定在内胆时，另一风道总成可以沿着内胆的进深方向朝向固定的风道总成移动并实现相互压合对接，第一倾斜端面214a和第二倾斜端面224a在相互导向的过程中不会产生机械干涉。
在一些进一步的实施例中，第一压合面214还可以进一步地包括第一竖向后端面214b，其自第一倾斜端面214a的后端向下延伸形成。第二压合面224还可以进一步地包括第二竖向后端面224b，其自第二倾斜端面224a的后端向下延伸形成。第一竖向后端面214b被配置成使得导风风道总成220向后平移时与第一竖向后端面214b的后表面相抵靠，以实现止档和定位。
当第一竖向后端面214b与第二竖向后端面224b相抵靠时，第一倾斜端面214a与第二倾斜端面224a恰好相互压合对接，使得引风对接口212和导风对接口222无缝衔接起来。
在另一些进一步的实施例中，第一压合面214还可以进一步地包括第一竖向前端面214c，其自第一倾斜端面214a的前端向上延伸形成。第二压合面224还可以进一步地包括第二竖向前端面224c，其自第二倾斜端面224a的前端向上延伸形成。第一竖向前端面214c被配置成使得导风风道总成220向后平移时与第二竖向前端面224c的后表面相抵靠，以实现止档和定位。
当第一竖向前端面214c与第二竖向前端面224c相抵靠时，第一倾斜端面214a与第二倾斜端面224a也恰好相互压合对接，使得引风对接口212和导风对接口222无缝衔接起来。
在一些实施例中，第一压合面214可以包括第一倾斜端面214a、第一竖向后端面214b和第一竖向前端面214c，相应地，第二压合面224可以包括第二倾斜端面224a、第二竖向后端面224b和第二竖向前端面224c。在另一些实施例中，第一压合面214可以包括第一倾斜端面214a和第一竖向后端面214b，相应地，第二压合面224可以包括第二倾斜端面224a和第二竖向后端面224b。在又一些实施例中，第一压合面214可以包括第一倾斜端面214a和第一竖向前端面214c，相应地，第二压合面224可以包括第二倾斜端面224a和第二竖向前端面224c。
利用多个不同位置的端面进行压合对接，可使分体式风道组件200的各个风道总成在相对移动时实现止档和定位，从而提高分体式风道组件200的各个风道总成之间的连接精度。
当然，在一些其他实施例中，第一压合面214可以仅包括第一倾斜端面214a，第二压合面224可以仅包括第二倾斜端面224a。此时借助人工导向，或者借助外部导向结构，同样可以使分体式风道组件200的各个风道总成在相对移动时实现止档和定位。
在一些可选的实施例中，第一压合面214还可以进一步地包括第一水平端面214d，其自第一竖向前端面214c的顶端水平向外延伸形成。第二压合面224还进一步地包括第二水平端面224d，其自第二竖向前端面224c的顶端水平向外延伸形成。当引风风道总成210和导风风道总成220设置在内胆后壁处时，第一水平端面214d自第一竖向前端面214c的顶端水平向前延伸形成，第二水平端面224d自第二竖向前端面224c的顶端水平向前延伸形成。
第一水平端面214d的下表面与第二水平端面224d的上表面相抵靠，以托举引风风道总成210，这可以提高引风风道总成210的装配结构的稳定性，从而减少或避免两个风道总成之间的 压合对接产生缝隙。
在一些可选的实施例中，导风风道总成220设置有弹性件250，弹性件250的外形与第二压合面224的外形相适配，以覆盖第二压合面224且避让导风对接口222，用于与第一压合面214相互挤压，实现密封。例如，当第一压合面214包括第一倾斜端面214a、第一竖向后端面214b、第一竖向前端面214c以及第一水平端面214d，第二压合面224相应地包括第二倾斜端面224a、第二竖向后端面224b、第二竖向前端面224c以及第二水平端面224d时，弹性件250可以覆盖在第二倾斜端面224a、第二竖向后端面224b、第二竖向前端面224c以及第二水平端面224d上，使得每组相互压合的端面之间实现密封。
该弹性件250同样可以为用于密封接口的弹性密封材料制成。由于弹性密封件的设置是本领域技术人员所悉知的，在此不做赘述。为便于区分，引风风道总成210上所设置的弹性件270可以命名为第一弹性件，导风风道总成220上所设置的弹性件250可以命名为第二弹性件。
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。
