本发明涉及冷藏冷冻技术领域，特别是涉及一种冰箱及其风道系统。
背景技术
对于传统的对开门风冷冰箱而言，其风门总成的布置方式通常有两种，一种是将风门总成布置在冷冻间室的后侧，此种布置方式下，风门有结冰或结霜的风险，需要同时配设加热丝。另一种是将风门总成布置在冷藏间室的顶部，此种布置方式下，冷藏间室的顶部会形成凸包，美观性较差。
除此，对于左侧为冷冻间室、右上为冷藏间室、右下为变温间室的对开门风冷冰箱而言，其变温间室通常需要单独设置蒸发器成为独立系统，或者需要从冷冻间室引入风管，导致制造成本较高，因此还有待改善。

可选地，冷藏内胆的内部设置有中隔板，中隔板将冷藏内胆的内部空间分隔成上下相邻的第一间室和第二间室；
冷藏风道包括冷藏上风道和冷藏下风道，冷藏上风道位于第一间室，冷藏下风道位于第二间室，冷藏上风道的下端和冷藏下风道的上端分别与送风风道相连通。
可选地，风门总成包括两个第二风门组件，其中一个第二风门组件设置在送风风道对应冷藏上风道下端的位置处，另一个第二风门组件设置在送风风道对应冷藏下风道的上端的位置处。
可选地，第二风门组件包括第二门框和第二风门，第二门框沿送风风道的横向方向设置在第二风道内，其上开设有供气流纵向通过的第二风口，第二风门设置在第二风口处，其一侧的左右两端具有第二转轴，第二转轴与第二门框枢转连接。

根据本发明的第二方面，本发明提供了一种冰箱，包括冷冻内胆和冷藏内胆，冷冻内胆与冷藏内胆左右相邻设置，并采用上述中任意一种风道系统。
本发明的冰箱及其风道系统，由于其风门总成设置在送风风道邻近冷藏风道一端的内部，远离冷冻风道内的送风装置，因此，可有效避免风门总成出现结冰或结霜现象，无需再为风门总成单独配置加热丝，降低了冰箱的制造成本。
进一步地，本发明的冰箱及其风道系统，其两个第二风门组件可分别用于控制冷藏上风道和冷藏下风道内的气流通断，使得第一间室与第二间室的冷量供应互不影响，实现了冷藏内胆下部间室(即第二间室)的全变温。

冷冻风道210形成于冷冻内胆110的后侧，冷冻风道210沿冷冻内胆110的高度方向可分为自上而下依次连接的冷冻上风道211和冷冻下风道212，冷冻上风道211的前侧具有多个冷冻出风口，冰箱10的蒸发器可安装在冷冻下风道212的后侧，冰箱10的送风装置可安装至冷冻上风道211的底部，用于从蒸发器处吸收冷量，将冷量输送至冷冻上风道211，并从冷冻出风口吹出，从而调节冷冻内胆110的内部温度。
冷藏风道220形成于所述冷藏内胆120的后侧，冷藏风道220的前侧设置有多个冷藏出风口。送风风道230的一端与冷冻风道210(具体为冷冻上风道211的送风装置所在位置处)相连通，另一端与冷藏风道220相连通。送风装置在朝向送风风道230送风的过程中，将从蒸发器处吸收的冷量输送至冷藏风道220内，并从冷藏出风口吹出，从而调节冷藏内胆120的内部温度。
需要说明的是，本实施方式中的送风装置为分路送风装置，也即，其可以受控地仅朝向冷冻上风道211送风，也可以受控地仅向送风风道230送风，还可以同时向冷冻上风道211和送风风道230送风。由于分路送风装置的具体结构及工作原理为本领域的技术人员所习知，因此，这里不再赘述。
参照图3，风门总成300设置在送风风道230邻近冷藏风道220一端的内部，用于受控地启 闭送风风道230，从而在需要调节冷藏内胆120的内部温度时允许气流通过，在不需要调节冷冻内胆110的内部温度时阻断气流通过。
本发明实施例的风道系统200，由于其风门总成300设置在送风风道230邻近冷藏风道220一端的内部，远离冷冻风道210内的送风装置，因此，可有效避免风门总成300出现结冰或结霜现象，无需再为风门总成300单独配置加热丝，降低了冰箱10的制造成本。
图4是根据本发明一个实施例的风门总成300的结构示意图，图5是根据本发明一个实施例的第一风门组件310的结构示意图。
参照图4和图5，风门总成300可包括第一风门组件310，第一风门组件310包括第一门框311和第一风门312，第一门框311在送风风道230内从上至下朝向气流流动方向倾斜设置，其上开设有供气流横向通过的第一风口314，第一风门312设置在第一风口314处，其一侧的上下两端具有第一转轴313，第一转轴313与第一门框311枢转连接。通过此种方式，可以防止冷凝水冻住第一转轴313，确保第一风门312启闭的顺畅性。
参照图2或图3，冷藏内胆120与冷冻内胆110的下端之间设置有回风风道240，回风风道240的回风进口与冷藏内胆120的内部相连通，回风风道240的回风出口与冷冻风道210的内部相连通。回风风道240可将冷藏内胆120中的回风引入至冷冻风道210(具体为冷冻下风道212的蒸发器处)，经蒸发器重新进行冷却。
参照图6，回风风道240的截面面积可以自回风进口的一侧至回风出口的一侧逐渐减小。通过此种方式，可以使送风装置在送风过程中，冷藏内胆120底部的气流能够被快速地吸进回风风道240，可加快气流循环速度，提高对冷藏内胆120的制冷效率。
图7是根据本发明另一个实施例的冰箱10的结构示意图，参照图7，冷藏内胆120的内部设置有中隔板130，中隔板130将冷藏内胆120的内部空间分隔成上下相邻的第一间室121和第二间室122。冷藏风道220可包括冷藏上风道221和冷藏下风道222，冷藏上风道221位于第一间室121，冷藏下风道222位于第二间室122，冷藏上风道221的下端和冷藏下风道222的上端分别与送风风道230相连通。如此，可通过冷藏上风道221和冷藏下风道222分别对第一间室121和第二间室122进行独立制冷，提高冷藏内胆120上下区域制冷的均匀性。
值得注意的是，在采用中隔板130将冷藏内胆120的内部分隔成独立的第一间室121和第二间室122之后，需要在第一间室121与冷冻风道210之间再单独设置回风风道240，以便在向第一间室121供应冷量的过程中，第一间室121的内部气流能够返回冷冻风道210。
图8是根据本发明另一个实施例的风门总成300的结构示意图，图9是根据本发明一个实施例的第二风门组件320的结构示意图。
参照图8和图9，风门总成300包括两个第二风门组件320，其中一个第二风门组件320设置在送风风道230对应冷藏上风道221下端的位置处，另一个第二风门组件320设置在送风风道230对应冷藏下风道222的上端的位置处。第二风门组件320可分别用于控制冷藏上风道221和冷藏下风道222内的气流通断，使得第一间室121与第二间室122的冷量供应互不影响，实现了冷藏内胆120下部间室(即第二间室122)的全变温，取消了常规设计中冷冻内胆110到第二间室122的送风管路。
在实际应用中，第一间室121根据制冷温度可以被配置成冰箱10的冷藏间室，而第二间室122可以根据存储需求相应地配置成冰箱10的冷藏间室或冷冻间室。也就是说，当需要冷藏存储的食材较多时，可以将第二间室122配置成冷藏间室，而当需要冷冻存储的食材较多时，可以将第二间室122配置成冷冻间室。
具体地，第二风门组件320可包括第二门框321和第二风门322，第二门框321沿送风风道230的横向方向设置在第二风道内，其上开设有供气流纵向通过的第二风口324，第二风门322设置在第二风口324处，其一侧的左右两端具有第二转轴323，第二转轴323与第二门框321枢转连接，通过转动第二转轴323可以较为方便地打开或关闭第二风门322。
进一步地，风门总成300还可以包括风门安装盒330，风门安装盒330装嵌在送风风道230内，其具有朝向冷冻风道210的气流进口以及分别朝向冷藏上风道221和冷藏下风道222的气流出口，两个第二门框321分别安装至两个气流出口处。在实际安装过程中，可以先将第二风门组件320安装至安装盒内，然后再将安装盒装嵌至送风风道230内，从而提高风门总成300安装的便利性。除此，风门总成300整体集成在冷藏内胆120的后侧，有效缩短了冷冻和第二间室122的送风路径。
风门安装盒330可以由泡沫材料制成，其包括前盒盖331和后盒盖332，前盒盖331扣合在后盒盖332的前侧，前盒盖331与后盒盖332之间形成上述中的气流进口和气流出口，当前盒盖331与后盒盖332扣合在一起时，实现对第二门框321的夹紧固定。
根据上述中任意可选实施例或多个可选实施例的组合，本发明实施例能够达到如下有益效果：
本发明实施例的冰箱10及其风道系统200，由于风门总成300设置在送风风道230邻近冷藏风道220一端的内部，远离冷冻风道210内的送风装置，因此，可有效避免风门总成300出现结冰或结霜现象，无需再为风门总成300单独配置加热丝，降低了冰箱10的制造成本。
进一步地，本发明实施例的冰箱10及其风道系统200，其两个第二风门组件320可分别用于控制冷藏上风道221和冷藏下风道222内的气流通断，使得第一间室121与第二间室122的冷 量供应互不影响，实现了冷藏内胆120下部间室(即第二间室122)的全变温。
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。
