此外，通过对第一风路隔热部件41的中间部分进行开口，而形成了多个开口部29。第一风路隔热部件41的开口部29的位置与风路罩42的出风口16的位置重叠。因此，在风路罩42中流通的空气的一部分经由开口部29和出风口16被吹出到冷藏室12。
与第一风路隔热部件41同样，第二风路隔热部件43由发泡树脂等的隔热材料构成，通过使其内部向前方凹陷，而形成了第三风路481和第四风路483。通过对第三风路481的上端部分进行开口，而形成了开口57，第二风路隔热部件43的开口57的位置与风路罩42的出风口47的位置一致。因此，在第三风路481中上升的空气经由开口57和出风口47被吹送到保鲜室15。所述风路48包括所述第一、第二、第三、第四风路481、482、483、484。
此外，通过对第四风路483的上端部分进行开口，而形成了开口56，开口56的位置与风路罩42的出风口45的位置一致。因此，在第一风路482中上升的空气经由开口56和出风口45被吹出到子冷藏室121。
所述风门30组装在第一风路隔热部件41的下端和第二风路隔热部件43的下端，具有对上述第三风路481等进行打开或关闭的功能。风门30具有第一挡板311、第二挡板312、第三挡板313和第四挡板314。第一挡板311设置在第三风路481，第二挡板312设置在第一风路482，第三挡板313设置在第四风路483，第四挡板314设置在第二风路484。稍后将参照图5等来描述风门30的细节。
图5A是从前侧上方观察风门30的立体图，图5B是从后侧下方观察风门30的立体图。在以下说明中，第一挡板311、第二挡板312、第三挡板313和第四挡板314统称为挡板31，第一挡板框架321、第二挡板框架322、第三挡板框架323和第四挡板框架324统称为挡板框架32。
参照图5A，所述风门30具有挡板31和挡板驱动部33，所述挡板驱动部33驱动这些挡板31的打开关闭动作。第一挡板311、第二挡板312、第三挡板313和第四挡板314在前后方向和左右方向上呈矩阵状配置。当从上方观察时，挡板31整体呈现大致矩形的外缘形状。
所述挡板驱动部33设置在第一挡板311和第二挡板312与第三挡板313和第四挡板314 之间。通过这样做，能够用一个挡板驱动部33来进行挡板31的打开关闭驱动。
此外，所述挡板31在挡板框架32内部进行打开关闭驱动。具体地，所述第一挡板311收纳在第一挡板框架321中，所述第二挡板312收纳在第二挡板框架322中，所述第三挡板313收纳在第三挡板框架323中，所述第四挡板314收纳在第四挡板框架324中。
参照图5B，通过对所述第一挡板框架321的底面进行开口，而形成了大致呈矩形的开口部581，当封闭图4所示的第三风路481时，通过第一挡板311封闭开口部581。同样，通过对第二挡板框架322进行开口，而形成了开口部582，当封闭图4所示的第一风路482时，通过第二挡板312封闭开口部582。此外，通过对第三挡板框架323进行开口，而形成了开口部583，当封闭图4所示的第四风路483时，通过第三挡板313封闭开口部583。此外，通过对第四挡板框架324进行开口，而形成了开口部584，当封闭图4所示的第二风路484时，通过第四挡板314封闭开口部584。
图6A是从前侧上方观察风门30和挡板31的立体图，图6B是从前侧上方观察挡板框架32的立体图。
参照图6A，在所述第一挡板311中，向左方侧突出的转动轴491形成在其后方左端部，向右方侧突出的转动轴492形成在其后方右端部。在第二挡板312中，向左方侧突出的转动轴493形成其在后方左端部，向右方侧突出的转动轴494形成在其后方右端部。在第三挡板313中，向左方侧突出的转动轴498形成在其后方左端部，向右方侧突出的转动轴497形成在其后方右端部。在第四挡板314中，向左方侧突出的转动轴496形成在其后方左端部，向右方侧突出的转动轴495形成在其后方右端部。在此图中，转动轴495被挡板驱动部33遮挡而未示出。
所述第一挡板311的转动轴491、第二挡板312的转动轴493、第三挡板313的转动轴497和第四挡板314的转动轴495以不可相对旋转的方式连接到后述的挡板齿轮374等。
参照图6B，通过将第一挡板框架321的左右方向上相对的壁部开口成大致圆形，而形成了孔部501和孔部502。同样，通过对第二挡板框架322进行开口，而形成了孔部503和孔部504。此外，通过对第三挡板框架323进行开口，而形成了孔部507和孔部508。此外，通过对第四挡板框架324进行开口，而形成了孔部505和孔部506。在此，孔部502、孔部504、孔部506和孔部508不一定必须形成为贯通孔，也可以形成为向左右方向外侧凹陷的凹状的非贯通孔。
图6A所示的第一挡板311的转动轴491和转动轴492可转动地***到图6B所示的第一挡板框架321的孔部501和孔部502中。同样，第二挡板312的转动轴493和转动轴494可转动地***到第二挡板框架322的孔部503和504中，第三挡板313的转动轴497和转动轴498可转动地***到第三挡板框架323的孔部507和孔部508中，第四挡板314的转动轴495和转动轴496可转动地***到第四挡板框架324的孔部505和孔部506中。
图7A是从前方右侧观察风门30的立体图，图7B是从前方右侧观察各齿轮的放大立体 图，所述各齿轮构成风门30。
参照图7A，挡板驱动部33具有多个齿轮，其位于风门30的中央位置并用于使挡板31转动。
参照图7B，挡板驱动部33具有电机34、电机齿轮35、从动齿轮364和从动齿轮363、以及挡板齿轮374和挡板齿轮373、374。
所述电机齿轮35由电机34旋转驱动，并与传动齿轮366啮合。传动齿轮366与从动齿轮364和从动齿轮362连成一体。在从动齿轮364的前方侧，配置有挡板齿轮374，从动齿轮364与挡板齿轮374啮合。第一挡板311的转动轴491以不可相对旋转的方式***到挡板齿轮374。因此，当通过电机34使电机齿轮35旋转时，该旋转力经由传动齿轮366、从动齿轮364使挡板齿轮374旋转，由此，第一挡板311转动。
在图8的立体图中，示出了仅第一挡板311处于打开状态而第二挡板312、第三挡板313和第四挡板314处于关闭状态的风门30。
参照图7B，所述挡板齿轮374的齿轮比小于从动齿轮364的齿轮比。如此，与从动齿轮364的旋转量相比，能够使挡板齿轮374更大幅度地旋转。例如，通过使从动齿轮364旋转80度，能够使挡板齿轮374旋转90度。因此，当使第一挡板311处于打开状态时，能够使第一挡板311可靠地为垂直状态，从而能够减小上述第三风路481的风路阻力。
此外，所述电机齿轮35与传动齿轮365啮合。传动齿轮365与从动齿轮363和从动齿轮361(参照图9B)成一体。在从动齿轮363的后方侧，配置有挡板齿轮373，从动齿轮363与挡板齿轮373啮合。挡板312的转动轴493以不可相对旋转的方式***到挡板齿轮373中。在此，挡板齿轮373也具有比从动齿轮363小的齿轮比，以便使挡板312在打开状态下可靠地转动90度。
图9A是从前方左侧观察风门30的立体图，图9B是从前方左侧观察各齿轮的放大立体图，所述各齿轮构成风门30。
参照图9B，所述从动齿轮362与上述传动齿轮366成一体。此外，在从动齿轮362的前方配置有挡板齿轮372，从动齿轮362和挡板齿轮372以能够啮合的方式配置。此外，挡板313的转动轴497以不可相对旋转的方式***并连接到挡板齿轮372。在此，挡板齿轮372的齿轮比也小于从动齿轮362的齿轮比，以便使挡板313在打开状态下可靠地转动90度。
所述传动齿轮365的前方部分与传动齿轮366啮合。此外，传动齿轮365与从动齿轮361和从动齿轮363(参照图7B)成一体。在从动齿轮361的后方侧配置有挡板齿轮371，从动齿轮361和挡板齿轮371以能够啮合的方式配置。挡板314的转动轴495以不可相对旋转的方式***到挡板齿轮371。
当通过电机34使电机齿轮35旋转时，该旋转力经由传动齿轮366、传动齿轮365和从动齿轮361使挡板齿轮371旋转，由此挡板314转动。在此，挡板齿轮371的齿轮比也小于从动齿轮361的齿轮比，以便使挡板314在打开状态下可靠地转动90度。
图10A是从前方上侧观察风门30和第一风路隔热部件41的立体图，图10B是从后方下侧观察风门30和第一风路隔热部件41的立体图，图10C是从前方上侧观察风门30的放大立体图。
参照图10A，在第一风路隔热部件41的下端形成有大致板状的***部521和***部522。此外，在***部521与***部522之间，形成有从前方观察时大致呈矩形状的狭缝51。
所述风门30的挡板驱动部33具有外壳38。外壳38由合成树脂大致形成为长方体形状。在外壳38的内部设置有构成上述挡板驱动部33的齿轮等。
参照图10B，所述抵接部49设置在狭缝51的后方侧。抵接部49是对第一风路482和第二风路484进行分隔的部分的下端面，其既可以是平坦面，也可以是使后述凹部40反转的形状。
参照图10C，在外壳38的上表面形成有凹部40。凹部40被形成为在外壳38的上表面沿前后方向呈直线状延伸。此外，凹部40也被形成为在外壳38的上表面沿左右方向呈直线状延伸。换言之，凹部40在外壳38的上表面形成为大致十字状。
所述风门30的外壳38***到图10B所示的狭缝51中。此外，形成有凹部40的外壳38的上表面与抵接部49抵接。由此，密封了外壳38的上表面与第一风路隔热部件41的抵接部49之间，将第一风路482与第二风路484分离，例如能够防止空气从第一风路482侵入到第二风路484。
在此，也可以代替上述凹部40，而在外壳38的上表面形成肋，使得该肋与抵接部49相抵接。
此外，参照图10C，在第一挡板框架321和第二挡板框架322之间形成有间隙532。进一步地，第一挡板框架321的挡板壁部3221朝向所述间隙532，第二挡板框架322的挡板壁部3211朝向所述间隙532，也即所述挡板壁部3221和挡板壁部3211之间间隔形成所述间隙532。此外，第二挡板框架322的挡板壁部3211被设置为高于第一挡板框架321的挡板壁部3221。
同样地，所述第四挡板框架324的挡板壁部3241隔着间隙531与第三挡板框架323的挡板壁部3231相对设置。此外，所述挡板壁部3241被设置为高于挡板壁部3231。
由此，能够容易地将图10A所示的第一风路隔热部件41的***部521和***部522***到风门30的间隙531和间隙532中。具体地，当将第一风路隔热部件41的***部521***到风门30的间隙531中时，较高地形成的挡板壁部3241用作引导板。此外，由于挡板壁部3241和挡板壁部3231的高度不同，所以在间隙531的上部形成了较大的开口，能够将***部521容易地***到间隙531中。
同样，在图10C所示的风门30的右方侧，挡板壁部3211被设置为高于挡板壁部3221，由此，能够将图10A所示的第一风路隔热部件41的***部522容易地***到间隙532中。
图11A是从前方上侧观察风门30和第一风路隔热部件41的立体图，图11B是从后方 下侧观察风门30和第一风路隔热部件41的立体图，图11C是从前方上侧观察风门30的放大立体图。
参照图11C，第二挡板框架322、第三挡板框架323和第四挡板框架324由合成树脂一体地形成。此外，在第三挡板框架323和第四挡板框架324之间形成大致水平的平坦面62。如此，能够使抵接面64与风门30的平坦面62紧密抵接，而能够对由第三挡板313打开关闭的第四风路483和由第四挡板314打开关闭的第二风路484进行分隔，所述抵接面64是图11B所示的风门30的下表面。
此外，参照图11C，挡板31的外侧面63为大致平坦的平坦面。具体地，外侧面63例如是第二挡板框架322的右方侧面和前方侧面、外壳38的右侧面和前侧面、第三挡板框架323的前侧面和左侧面、以及第四挡板框架324的左侧面。如此，能够使风门30的外侧面63与内面61抵接，所述内面61形成在图11B所示的第一风路隔热部件41的下端，而能够将各风路和风门30之间密封。
图12是各挡板和各风路的剖切立体图。
如上所述，所述风门30具有第一挡板311和第二挡板312，在第一挡板311和第二挡板312之间设置有空穴部60。所述空穴部60是截面为帽形状的合成树脂所形成的内部空间。如上所述，所述第一挡板311对第三风路481进行打开关闭，第二挡板312对第一风路482进行打开关闭。
图13A是示出仅第一挡板311处于打开状态的情况的剖视图，图13B是示出仅第二挡板312处于打开状态的情况的剖视图。
参照图13A，当以转动轴492为旋转中心来使第一挡板311旋转大约90度由此成为打开状态时，由上述蒸发器162冷却的低温空气经由第三风路481和开口57被吹出到保鲜室15。此时，由于存在空穴部60，而使第三风路481和第一风路482彼此隔热，防止了第二挡板312的转动轴494冻结。
参照图13B，能够以转动轴494为中心来使挡板312旋转大约90度由此成为打开状态，从而经由第一风路482向冷藏室12吹送空气。此时，第一挡板311以转动轴492为旋转中心，沿与上述相反的方向旋转大约90度，由此成为关闭状态。此时，第一风路482和第三风路481由空穴部60隔热，由此，能够抑制转动轴492冻结。
根据上述本实施方式，能够获得以下主要效果。
参照图5A，能够提供一种冰箱10，该冰箱10包括风门30，该风门30具有紧凑的外形形状并且能够减小风路阻力。即，通过沿前后方向和左右方向配置多个挡板31，能够减小风门30中的风路阻力，进一步地，能够减小左方侧的风路48和右方侧的风路48之间的风量差。因此，能够高效地将各储藏室冷却到预定的温度。
此外，参照图5A，通过在挡板31彼此之间配置挡板驱动部33，能够用一个挡板驱动部33来有效地驱动所有挡板31的打开或关闭动作。
此外，参照图9B，通过使挡板齿轮371的齿轮比小于从动齿轮的齿轮比，能够通过从动齿轮的小的旋转，来获得挡板齿轮371的大的旋转量，从而能够可靠地进行挡板31的打开关闭工作。
此外，参照图10C，通过使设置在外壳38的外表面上的肋或凹部40与第一风路隔热部件41抵接，能够密封其与挡板驱动部33的外壳38之间的间隙，从而能够防止空气从两者的间隙中泄漏。
此外，参照图10C，在第一挡板框架321与第二挡板框架322之间的间隙中，第一挡板框架321的挡板壁部3221和所述第二挡板框架322的挡板壁部3211中的一个被设置为比另一个高，由此，能够将第一风路隔热部件41的下端容易地***到第一挡板框架321和第二挡板框架322之间的间隙中。
此外，参照图11C，所述第三挡板框架323和第四挡板框架324一体地形成，由此，能够可靠地分离各挡板31被设置的风路48。
此外，参照图11C，所述第二挡板框架322至第四挡板框架324的外侧面63为平坦面，由此，能够使第一挡板框架321和第二挡板框架322的外侧面63与第一风路隔热部件41抵接，提高了风路48的气密性。
此外，参照图13A，能够通过空穴部60来使挡板31彼此隔热，当挡板311处于打开状态时，能够防止相邻的挡板312的驱动结构冻结。
以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围。
