发明内容
发明要解决的课题
然而，在上述现有技术的冰箱中，为了提高冰箱的冷却性能，遮蔽装置以及送风机存在需要改善之处。
具体而言，要提高冰箱的冷却性能，提高向贮藏室供给的空气的送风效率、增加空气的流量是有效的。然而，在上述专利文献1以及专利文献2所公开的送风机的构成中，如图13所示，由于在空气的流路上存在用于支撑风扇电机143的支撑架148，因此存在空气的流动被支撑架148阻碍的可能。
另外，像图14所示的专利文献2所公开的遮蔽装置250那样，在通过由安装于送风机的外壳的支撑基体251所支撑的驱动轴267来开闭送风机罩260的构成中，支承驱动轴267的支撑架258跨空气的流路而配置。故而，因在空气的流路上配置的支撑架258，会发生空气的流动损失。
另外，在专利文献2所公开的现有技术的冰箱中，存在如下风险：对送风机罩260进行开闭时的振动易于向间隔构件等传播，从而产生噪音。尤其是若为了提高冰箱的冷却性能，而对驱动轴267进行驱动以将送风机罩260推至支撑基体251，以提高在关闭送风机罩260时的密封性来抑制暖气的泄漏，则容易发生较大的振动或噪音。
本发明鉴于上述事实而提出，其目的在于，提供能在抑制来自遮蔽装置的振动或噪音的发生的同时提高送风效率从而提高冷却性能的冰箱。

冷藏室3和位于其下段的冷冻室4A被隔热间隔壁28划分开。冷冻室4A的内部的制冰室4与上段冷冻室5之间被间隔壁(附图中未表示)间隔。另外，制冰室4及上段冷冻室5与在它们的下段设置的下段冷冻室6之间，冷气流通自由地连通。而且，冷冻室4A与果蔬室7被隔热间隔壁29划分开。
在冷藏室3的背面，形成有被合成树脂制的间隔构件27划分且作为向冷藏室3提供冷气的供给风路的冷藏室供给风路14。在冷藏室供给风路14，形成有向冷藏室3吹出冷气的吹出口17。另外，在冷藏室供给风路14，设置有冷藏室风挡34。冷藏室风挡34是通过电机等进行驱动的开闭自由的风挡，用于控制提供给冷藏室3的冷气的流量，将冷藏室3内部的温度维持为适当水平。
在冷冻室4A的后方，形成有使经冷却器32冷却后的空气通过冷冻室4A的供给风路即冷冻室供给风路15。在冷冻室供给风路15的更后方，形成有冷却室13，在冷却室13内部，配置有用于使在冰箱内循环的空 气冷却的蒸发器即冷却器32。
冷却器32经由冷媒配管与压缩机31、未图示的散热器、未图示的膨胀阀或者毛细管连接，构成蒸气压缩式的冷冻循环回路。此外，在本实施方式所涉及的冰箱1中，作为所述冷冻循环的冷媒，使用了异丁烷，即R600a。
图3是表示冰箱1的供给风路的概略构成的主视图。如图3所示，冰箱1具备将冷藏室3与果蔬室7相连的果蔬室供给风路16。由此，提供给冷藏室3的冷气从在冷藏室3的下部形成的返回口21流入果蔬室供给风路16，并从吹出口20吹出后提供给果蔬室7。如图2所示，在果蔬室7，形成有与冷却室13的下部相连的返回口24，果蔬室7内的空气从返回口24向冷却室13的下部流动。
此外，还能采用以下构成：不仅设置用于使空气从冷藏室3向冷却室13返回的返回风路，还设置用于将冷却室13或冷冻室供给风路15与果蔬室7相连的果蔬室供给风路，将冷气从冷却室13不经由冷藏室3而提供给果蔬室7。另外，为了控制提供给果蔬室7的冷气的流动，可以设置果蔬室风挡。
图4以及图5是表示冰箱1的冷却室13附近的构造的侧面截面图，图4示出送风机罩60打开的状态，图5示出送风机罩60关闭的状态。
如图4所示，冷却室13在隔热箱体2的内部设置于冷冻室供给风路15的里侧。冷却室13与冷冻室供给风路15或冷冻室4A之间由合成树脂制的间隔构件25间隔。即，冷却室13是被内箱2b与间隔构件25夹持所形成的空间。
在冷却室13的前方形成的冷冻室供给风路15是形成于间隔构件25与其前方所安装的间隔构件35之间的空间，是经冷却器32冷却后的冷气所流动的供给风路。冷冻室供给风路15的上部与冷藏室供给风路14相连。
在间隔构件35，形成有向冷冻室4A吹出冷气的开口即吹出口18。在下段冷冻室6的下部背面，形成有使空气从冷冻室4A向冷却室13的下部返回的返回口23。
另外，在冷却器32的下方，设置有除霜加热器33作为将附着于冷却器32的霜融化后去除的除霜手段。除霜加热器33是电阻加热式的加热器。此外，作为除霜手段，例如还能采用：不利用电加热器的周期除霜(off-cycle defrost)、热气除霜(hot gas defrost)等其他除霜方式。
在冷却室13上部的间隔构件25，形成有与冷冻室供给风路15相连的开口即送风口26。在送风口26的前方，配设有将冷气向冷冻室4A等送出的送风机40。送风机40是具备离心式的风扇42的离心式送风机。
在送风机40的前方，设置有具有可动式的送风机罩60的遮蔽装置50。如图5所示，送风机罩60从冷冻室供给风路15侧向送风机40接近，覆盖送风机40以及送风口26。
送风机罩60被设置于间隔构件35侧的驱动轴67驱动而在前后方向上移动。如图4所示，送风机罩60向前方移动而从送风机40远离，从而在送风机罩60与间隔构件25之间形成空气能流通的流路。由此，经冷却器32冷却后的空气被送风机40送出后提供给冷藏室3、冷冻室4A以及果蔬室7。
此外，如图5所示，送风机罩60向后方移动而接近送风机40，从而送风机40被送风机罩60覆盖，送风口26被堵住，冷气所流动的风路被遮蔽。
此外，送风机罩60的与送风机40对置的面大致成形为凹形状。由此，送风机罩60不与在送风口26的前方配置的送风机40的风扇42接触，而送风机罩60的侧面部的后方端与间隔构件25的前表面抵接，从而 能封堵送风口26。
上述遮蔽装置50的开闭动作由未图示的控制装置控制，例如在对附着于冷却器32的霜进行去除的除霜运行时，如图5所示，关闭送风机罩60。
具体而言，若继续冷却运行，则霜会附着于冷却器32的空气侧传热面，阻碍传热，封堵空气流路。为此，控制装置根据冷媒蒸发温度的下降等来判断着霜或通过除霜定时器等来判断着霜，并启动用于将附着于冷却器32的霜去除的除霜运行。
在除霜运行下，控制装置停止压缩机31，对除霜加热器33通电。由此，附着于冷却器32的霜融化。此时，如图5所示，送风口26被送风机罩60堵住。由此，能防止经除霜加热器33加热后的冷却室13内的空气向冷冻室供给风路15流出。其结果，能提高冰箱1的冷却性能。
另外，若冷却器32的去霜完成，则控制装置停止除霜加热器33的通电，启动压缩机31，开始冷冻电路所执行的冷却。而且，控制装置在检测到冷却器32以及冷却室13被冷却至给定的温度后，或定时器等经过给定的时间后，如图4所示，打开送风机罩60，开始送风机40的运行。由此，能抑制除霜热所致的影响，重启冷却运行。
接下来，参照图6至图12来详细说明遮蔽装置50。图6是遮蔽装置50的分解立体图。如图6所示，遮蔽装置50具有：开闭自由地遮挡送风机40的送风机罩60、支撑送风机40且将送风机罩60滑动自由地支撑的基底构件51、以及对送风机罩60进行开闭驱动的驱动轴67。
遮蔽装置50安装于将冷冻室4A与冷冻室供给风路15划分开的间隔构件35的冷冻室供给风路15侧。具体而言，在间隔构件35的后表面，形成有大致圆形状的向前方凹陷的凹部36，遮蔽装置50配设于凹部36。即，间隔构件35中，仅相当于配设遮蔽装置50的凹部36之处向前方突出。如此，遮蔽装置50配设于凹部36内，从而能减少间隔构件35向冷冻室4A侧的突出，将冷冻室4A的收纳容积确保得较宽敞。
在间隔构件35的面向冷冻室供给风路15侧的主面，具体而言，在凹部36内的面，用于固定基底构件51的支轴部37以及卡止片38分别以3个一组向后方突出。基底构件51通过形成于凹部36的支轴部37以及卡止片38而在间隔构件35被固定且支撑。细节将后述。
在基底构件51，形成有以在前后方向上能滑动的方式支撑送风机罩60的大致圆柱状的导向销52。导向销52设有3根，分别从基底构件51朝向后方，与风扇42的旋转轴大致平行地延伸。在送风机罩60，形成有用于使导向销52滑动自由地进行嵌合的导向孔62。导向销52在导向孔62内插通，对送风机罩60的往复运动进行导向。
在基底构件51，安装有用于使送风机罩60往复运动的驱动轴67。驱动轴67与形成于基底构件51的轴支撑部55嵌合，以旋转自由的方式被支撑。
驱动轴67呈大致圆筒形状，并设置有使其侧面的一部分连续凸起为螺旋状的螺丝牙68。而且，驱动轴67与形成于送风机罩60的螺丝孔63螺合。另外，在驱动轴67或者轴支撑部55，内置有未图示的电机，通过该电机的驱动力，驱动轴67旋转给定角度。在驱动轴67旋转至给定方向时，送风机罩60接近送风机40，风路成为关闭状态。另一方面，在驱动轴67相对于所述给定方向被逆旋转驱动时，送风机罩60从送风机40分离，风路成为开通状态。
送风机罩60将合成树脂件大致注塑成形为盖形状，具有呈大致圆形状的主面部以及从该主面部的周边缘 部向后方延伸设置的侧面部。此外，前述的导向销52以及与之嵌合的导向孔62配置于所述侧面部的外侧。由此，在已关闭送风机罩60时，空气不会经过导向孔62而从送风机罩60的内侧向外侧泄漏，送风机罩60的密封性得以提高。
另外，在送风机罩60的所述主面部的中央附近，以大致圆形状地贯通而在内侧形成有带螺丝槽的螺丝孔63。另外，在送风机罩60，为了将间隔构件35与基底构件51进行固定，形成有贯通孔61，贯通孔61使形成于基底构件51的支撑部53滑动自由地相嵌合。
送风机40是包含离心式的风扇42、用于对风扇42旋转驱动的风扇电机43、以及支撑风扇电机43的风扇基底41在内的离心式送风机。风扇基底41安装于基底构件51而被支撑。
此外，在冰箱1的生产工序中，上述送风机罩60、驱动轴67以及送风机40预先安装于基底构件51。然后，将遮蔽装置50以及送风机40一体装配的状态下的装配品对间隔构件35进行安装。
图7是表示冰箱1的遮蔽装置50附近的立体截面图。此外，图7示出了将送风机罩60打开的状态。如图7所示，将冷却室13与冷冻室供给风路15相连的送风口26是大致圆形状的开口，其周围缘部以截面大致半圆状向冷却室13侧突出。
送风机40的风扇42以其旋转轴与送风口26的中心轴大致同轴的方式配设于送风口26的前方。如前所述，送风机40是离心式，从风扇42的冷却室13侧的中央附近吸入空气，在半径方向上能效率良好地送出空气。由此，与现有技术那样采用轴流送风机的情况相比，能提高送风效率，增大送风量。
如图7的A部所示，基底构件51在支撑部53被形成于间隔构件35的支轴部37支撑，并支撑送风机40的风扇基底41。另外，如图7的B部所示，基底构件51在形成于外周部的弹性部57处与形成于间隔构件35的卡止片38卡合，且被固定于间隔构件35。即，遮蔽装置50以及送风机40被间隔构件35支撑。
通过这样的构成，能将对送风机40的风扇电机43进行支撑的风扇基底41、对驱动送风机罩60的驱动轴67进行支撑的基底构件51全部相对于风扇42而配置于间隔构件35侧。
由此，如图7所示，在送风机罩60已打开时，支撑风扇电机43的构件、支撑驱动轴67的构件未在空气的流路上配置，因此空气的流路不会因这些构件而受到妨碍。由此，能降低从送风机40送出的空气的流动损失，使提供给冷冻室4A等贮藏室的空气的流量增大，提高冰箱1的冷却性能。
图8是图7所示的A部附近的放大截面图，示出了支撑部53附近的构造。图9(A)是设置于支撑部53的缓冲构件70的纵截面图。图9(B)是图9(A)所示的C-C线截面图，示出了缓冲构件70的横截面。
如图8所示，在基底构件51，形成有用于使在间隔构件35形成的支轴部37插入的支撑孔53a。具体而言，在基底构件51，形成有在前后方向上延伸且至少间隔构件35侧开口的大致圆筒形状的支撑部53，支撑部53的内周侧成为支撑孔53a。而且，间隔构件35的支轴部37经由缓冲构件70而与基底构件51的支撑孔53a嵌合，从而基底构件51被间隔构件35支撑。
缓冲构件70例如是合成橡胶成形品等弹性体，如图9(A)以及(B)所示，具有呈大致圆筒形状的形态的嵌合部71、以及从嵌合部71的一端部附近向外径侧环状突出设置的法兰盘部73。
如图8所示，缓冲构件70的嵌合部71嵌插在基底构件51的支撑孔53a内。另外，间隔构件35的支轴部37与嵌合部71的内孔72嵌合。而且，缓冲构件70的法兰盘部73被间隔构件35的主面与基底构件51夹持。由此，能通过缓冲构件70的嵌合部71使对支轴部37在半径方向上的振动衰减，并通过法兰盘部73使 与间隔构件35的主面垂直的方向上的振动衰减，从而将上下左右前后方向的振动抑制为适当水平。
如此，基底构件51经由缓冲构件70而被固定于间隔构件35，从而能抑制来自对送风机罩60进行驱动的驱动轴67(参照图7)的振动被传播至间隔构件35，能抑制噪音的增大。
另外，如图9(B)所示，在缓冲构件70的内孔72，形成有向内侧突出的凸部74。即，参照图8以及图9，缓冲构件70具有从间隔构件35的与支轴部37对置的内孔72的面突出的凸部74，并在凸部74处与间隔构件35抵接。由此，能减少间隔构件35与缓冲构件70的接触面积，能抑制振动的传播，获得良好的减振效果。
此外，凸部74的形状并不限于此，还可以形成为大致直线状、大致螺旋状、大致点状等。另外，与凸部74同等的凸形状可以形成于缓冲构件70的与基底构件51对置的面，例如，形成于嵌合部71的外周面或法兰盘部73等。由此，能减少基底构件51与缓冲构件70的接触面积，提高减振效果。
如图8所示，支撑部53的外周与形成于送风机罩60的贯通孔61以滑动自由的方式嵌合。由此，送风机罩60能在前后方向上往复移动，从实线所示的打开状态的位置到点划线所示的关闭状态的位置，以接近或远离送风机40的方式移动。
支撑部53的后端附近呈高低差状，形成有小径的送风机支撑部54。在送风机支撑部54，嵌入有大致圆筒形状的缓冲构件75，并通过缓冲构件75而安装有送风机40的风扇基底41。具体而言，在缓冲构件75的外周面，形成有环状的凹槽，形成于风扇基底41的支撑孔44被嵌入该凹槽。
也就是，支撑部53是兼具用于将基底构件51固定至间隔构件35的支轴部37的功能以及用于将送风机40固定至基底构件51的功能的构造。如此，通过由基底构件51的支撑部53来固定间隔构件35和送风机40两者的构成，能抑制基底构件51的形状复杂化。另外，能减小遮蔽装置50的前后方向的尺寸，能确保冷冻室4A的收纳容积较宽。
图10是遮蔽装置50的分解立体图。如图10所示，在基底构件51的外周部附近，与从间隔构件35的后表面突出设置的卡止片38的位置相对应地，形成有3处弹性部57。
弹性部57构成为：通过沿基底构件51的外周部形成的切缝(slit)58，能向基底构件51的中央侧弹性变形。由此，弹性部57在基底构件51安装于间隔构件35时发生变形以容许卡止片38的爪部39(参照图11)通过。
另外，在送风机罩60的主面的基底构件51侧，与基底构件51的弹性部57的位置相对应地，形成有向基底构件51侧突出的按压部64。在基底构件51向间隔构件35安装时，按压部64与基底构件51的弹性部57附近抵接来按压基底构件51。此外，关于卡止片38、弹性部57以及按压部64的细节，参照图11进行后述。
另外，在基底构件51，形成有从基底构件51的冷冻室4A侧向冷却室13侧贯通的大致角筒形状的布线路径部56。与之对应，在送风机罩60，从冷冻室4A侧贯通至冷却室13侧，形成有使布线路径部56插通的布线孔65。关于细节，参照图12进行后述。
图11(A)是图7所示的B部附近的放大截面图，示出了基底构件51与卡止片38的卡合部附近。图11(B)是表示基底构件51与卡止片38的卡合部附近的立体图。
如图11(A)所示，在从间隔构件35的主面突出设置的卡止片38，形成有与在基底构件51的外周部附 近形成的弹性部57相卡合的爪部39。如前所述，基底构件51的弹性部57通过形成切缝58而自由变形。由此，在基底构件51向间隔构件35安装时，弹性部57朝基底构件51的中央侧弹性变形，卡止片38的爪部39被推入至弹性部57的后表面侧。而且，卡止片38与弹性部57卡合，基底构件51固定于间隔构件35。如此，通过在基底构件51的外周部附近形成弹性部57，从而将基底构件51安装至间隔构件35的作业变得容易。
如图11(A)以及(B)所示，在切缝58的周围缘，按照包围切缝58的方式形成有从该周围缘延伸至送风机罩60侧的缘曲部59。由此，弹性部57附近的刚性得以提高，弹性部57在前后方向上的变形得以抑制。由此，将基底构件51安装至间隔构件35的作业变得容易，而且能将基底构件51牢固地固定至间隔构件35。
另外，如图11(A)所示，在基底构件51的弹性部57的间隔构件35侧的角部，形成有倒角形状的倾斜部57a。由此，在将基底构件51向间隔构件35进行安装时，弹性部57被卡止片38的爪部39按压，在基底构件51的中央侧易于变形。由此，安装基底构件51的作业变得容易。
另外，通过在由基底构件51的卡止片38固定的部位形成弹性变形自由的弹性部57，能抑制从遮蔽装置50的驱动轴67(参照图6)等发生的振动或噪音向间隔构件35传播。即，弹性部57发挥减振功能。
另外，通过设置可弹性变形的弹性部57的构成，将无需使卡止片38较大变形。由此，能缩短卡止片38。由此，能减小遮蔽装置50的安装部附近的前后方向的尺寸，能确保冷冻室4A的收纳容积较宽。
另外，如前所述，在送风机罩60的基底构件51侧的主面，在与弹性部57附近对应的位置，形成有向基底构件51侧突出的按压部64。由此，在基底构件51被安装于间隔构件35时，按压部64与基底构件51的弹性部57附近具体而言缘曲部59的后端相抵接来按压基底构件51。由此，基底构件51的前后方向的变形得以抑制，能使弹性部57与卡止片38容易卡合。
也就是，通过按压预先一体组装的遮蔽装置50的送风机罩60附近来向间隔构件35推入，能使基底构件51与卡止片38容易卡合，能容易地安装遮蔽装置50。
另外，通过这样的构成，不需要为了按压基底构件51而在弹性部57或卡止片38的附近确保能使作业者的手指等插入的空间。由此，能缩窄遮蔽装置50的周边空间，将冷冻室4A的收纳容积确保得较宽敞。
另外，如图11(B)所示，在相对于卡止片38的爪部39为相反侧的面，可以形成肋状的加强部38a，该加强部38a将卡止片38与间隔构件35的主面相连。由此，能抑制卡止片38的变形，防止基底构件51的脱落。
此外，还能采用如下方法：在基于上述卡止片38的基底构件51的固定方法的基础上，或者取而代之，通过螺丝等紧固构件来将基底构件51固定于间隔构件35。由此，能牢固地固定基底构件51。
图12是表示布线路径部56附近的截面图。如图12所示，基底构件51具有大致筒状的布线路径部56，布线路径部56沿送风机罩60的移动方向朝冷却室13侧延伸，并将基底构件51的间隔构件35侧与冷却室13侧相连。布线路径部56是用于使与送风机40的风扇电机43相连的布线77经过的路径。
在送风机罩60，以与布线路径部56的外周对应的形状，形成有用于使布线路径部56滑动自由地嵌合的布线孔65。而且，在布线孔65内插通有布线路径部56。由此，送风机罩60构成为：从实线所示的开状态的位置起到点划线所示的闭状态的位置为止，能沿布线路径部56往复移动。
通过上述构成，在将基底构件51固定于间隔构件35来提高送风性能的构成中，能使对在送风机罩60的 冷却室13侧配设的风扇电机43的布线从间隔构件35侧经由布线路径部56而通至送风机40侧。而且，使布线77插通的布线路径部56被未图示的密封构件等封堵。具体而言，在使布线77插通的布线路径部56的内部或者在基底构件51与间隔构件35之间，作为密封构件，例如设置合成树脂制的发泡片材等，从而封堵布线路径部56。或者，可以构成为：间隔构件35直接抵接至布线路径部56的开口周围，通过间隔构件35来封堵布线路径部56。通过这样的构成，能在确保送风机罩60的移动性的同时提高布线孔65的密封密封性能，能抑制在关闭送风机罩60时的暖气的泄漏，从而提高冰箱1的冷却性能。此外，向对驱动轴67进行驱动的电机的布线78穿过间隔构件35与基底构件51的间隙而从基底构件51的间隔构件35侧连接至电机。
在以上说明的实施方式中，作为送风机罩60，例示了在闭状态下覆盖送风机40的风扇42的前表面以及侧面全周的形态。然而，送风机罩60的形态不限于前述的例子。例如，在送风机罩60，可以形成容许在闭状态下使来自送风机40的空气对冷藏室3等特定的收纳室流通的开口部。通过这样的构成的送风机罩60与冷藏室风挡34、其他未图示的风挡等的组合，能对各收纳室根据各自的冷却负荷独立且高效地进行冷却。
本发明不限于上述实施方式，在其他不脱离本发明的主旨的范围内能实现各种变更实施。
