Description

冰箱 技术领域
本发明涉及冰箱。
背景技术
控制基板安装给定的电子部件，且对冰箱的各种负载(例如，温度传感器、LED冰箱内灯、送风风扇电动机等)进行控制；控制基板收容于包含钣金制的罩的盒体，例如配设于在冰箱的后部底方区域内设置的空间等(该空间有时也称为机械室)。包括这样的控制基板的安装结构的冰箱在下述专利文献1中公开。
专利文献1：JP特开2012-78008号公报。
专利文献1公开的技术是以如下为特征的冰箱，即，在包含钢板制的外箱的冰箱主体的外部轮廓壳体的后部底方设置给定的空间部，在该空间部的前侧设置凹状的基板收纳部，在基板收纳部经由绝缘性基板固定构件而收纳控制基板，且将包含控制基板的基板收纳部以钣金制的罩进行覆盖。
在所述空间部，除了控制基板以外，还配设有冷媒压缩压缩机、从该压缩机伸出的冷媒通路用配管、在此基础上的除霜水托盘等各种装置或部件。然而，在专利文献1公开的冰箱中，控制基板的表面或背面与所述空间的前侧平行设置，因此基板收纳部成为沿所述空间的宽度方向扩展的状态。另外，控制基板以及覆盖其的罩具有相应的厚度。故而，在该空间中，基板收纳部、控制基板、包含罩的控制基板配设空间的占有率高的状况会发生。进而，在所述前侧凹设用于收纳控制基板的基板收纳部的结果是，需要在空间前侧的预定处另行形成那样的特殊的形状，因此可能造成产品整体成本上升。
相对于这样的结构的冰箱，另外地，将包括由钣金制罩覆盖的阻燃性树脂壳体的控制基板收容盒体同样地配设于冰箱的机械室的结构的冰箱在市场上流通。在该冰箱中，冰箱外部轮廓的侧面底方侧被配置为兼作机械室的侧方边界。控制基板收容盒体的表面以及背面与机械室的侧方(冰箱外部轮廓的侧面)大致平行地竖立设置，且该控制基板收容盒体安装于所述侧方内侧。
然而，该控制基板收容盒体不仅防止对安装于控制基板的电子部件等的电磁障碍等，例如还尽量防止盒体内产生的燃烧向他处蔓延，因此采用以钣金制罩包围阻燃性树脂壳体的结构。故而，需要足以充分覆盖阻燃性树脂壳体的钣金制罩，这成为产品成本高的主因。随之，外观结构复杂化，控制基板收容盒体在机械室内的占有区域增加，对配置于其附近的其他装置或部件带来干扰的可能性会增加。

以下，参照附图来详细说明本发明的一实施方式所涉及的冰箱1。此外，在说明本实施方式所涉及的冰箱1时，“上下”方向对应冰箱1的高度方向，“左右”方向对应冰箱1的宽度方向，“前后”方向对应冰箱1的进深方向。
首先，参照图1来说明本实施方式所涉及的冰箱1的整体构成。在此，图1是冰箱1的侧视截面图。如图1所示，本实施方式所涉及的冰箱1包括相当于冰箱主体的隔热箱体2。隔热箱体2在内部包括贮藏食品等的多个贮藏室。另外，虽未特别限定，但多个贮藏室的每一个从上起依次对应冷藏室3、冷冻室4、蔬菜室5。
隔热箱体2的各贮藏室的前表面设置有开口，设置隔热门D1、D2、D3以分别将各开口以能开闭的方式堵塞。在此，例如在冰箱的正面观察下，隔热门D1的右端的上下端部可转动地支承于隔热箱体2，并对冷藏室3的前表面开口进行封堵。另外，隔热门D2配设为能相对于隔热箱体2沿前后方向拉出，并对冷冻室4的前表面开口进行封堵。同样，隔热门D3配设为能相对于隔热箱体2沿前后方向拉出，并对蔬菜室5的前表面开口进行封堵。
进而，隔热箱体2包括：钢板制的外箱2a、合成树脂制的内箱2b、以及在形成于外箱与内箱之间的间隙内填充的发泡聚氨酯制的隔热材2c。在隔热箱体2的内部配设多个隔热间隔壁(例如，以图1的标号6a、6b表示的构件)。通过该隔热间隔壁6a、6b来对冷藏室3、冷冻室4、蔬菜室5进行区划。
接下来，参照图2至图4来说明冰箱1的后部(背部)侧的构成。首先，参照图2。图2是冰箱1的后部侧立体图。如图所示，隔热箱体后部2r的底端区域以弯折基端部2rk为边进行弯折而向进深方向前方侧(冰箱内侧)延伸，并在延伸部分的预定处再次弯折进而向底方侧延伸。
在图2中，以标号2rf1表示弯折部分的前方侧延伸部，以标号2rf2表示底方侧延伸部。最终形成由该弯折部分2rf1、2rf2和隔热箱体2的两侧部2d中的底部后端域2dr1、2dr2围成的空间S。空间S的后方侧以及底方侧开口(以下，将该空间S称为“机械室”)。此外，所述弯折部分2rf1、2rf2以及底部后端域2dr1、2dr2成为将机械室S与其他区域分隔的壁材，以下有时将它们统称为“分隔壁”。
在机械室S内，配设有后述的基板收容部10、压缩机20、除霜水托盘30、散热管40等。隔热箱体2中的前述的底部后端域2dr1、2dr2是钢板制的外箱2a的一部分(以下，有时将隔热箱体2称为“冰箱外部轮廓”，另外，有时将所述箱体2的底部后端域称为“冰箱外部轮廓的(金属制)侧板”或“外部轮廓侧板”)。
在本实施方式中，从机械室S内的右(图2的左)起依次配置有基板收容部10、压缩机20、散热管40。在此，压缩机20由以覆盖机械室S的底方开口的方式安装的金属制(钢板制)的托台21载置。另外，在压缩机20的大致上方侧配置有除霜水托盘30。但这些机械室S内的位置关系不限于此。
另外，机械室S的位置也不限于所述冰箱1的后部底方域，还可以是其他位置。例如，机械室S可以设置于隔热箱体后部2r的上端域的预定位置。另外，还可以在机械室S配设其他装置/部件类。
接下来，参照图3以及图4。图3是冰箱1的后部底方域所涉及的放大图，示出所述各装置/部件类收纳于机械室S内的状态。另外，图4是从上方观察机械室S的内部的图。如图3以及图4所示，基板收容部10配置于机械室S内的右端(图3、图4的左端)，与金属制的外部轮廓侧板2dr的一方(在本实施方式中为外部轮廓侧板2dr1)相邻设置。进而，基板收容部10卡止于外部轮廓侧板2dr1的弯折后端缘2dr3。
基板收容部10的内部用以收容控制基板，控制基板安装有用于对冰箱1的各种动作进行控制的电子部件等。从控制基板延伸的布线(未图示)从在基板收容部10的例如上表面设置的布线插通孔向外伸出，与位于冰箱1内或机械室S的装置/部件类等连接。例如，配置于机械室S的大致中央的压缩机20经由所述布线与控制基板连接。
基板收容部10包括箱状的壳体部11和金属制罩部12，优选为钣金制罩部12。进而，如图4所示，本实施方式所涉及的基板收容部10包括用于将基板收容部10安装固定至弯折后端缘2dr3的金属制安装部13等。
在控制基板收容于壳体部11内时，控制基板的表面(或背面)成为与外部轮廓侧板2dr1大致平行的状态。故而，如图3以及图4所示，基板收容部10不在机械室S内占据过度宽的区域而收敛得较紧凑。能相应增加在机械室S收纳的其他装置/部件类的可占有空间。另外，由此，能防止与压缩机20、除霜水托盘30等与基板收容部10相邻设置的其他装置/部件类的接触。
虽未特别限定，但壳体部11优选为阻燃树脂制。由于壳体部11具有阻燃性，因此例 如即使在内部的控制基板燃烧的情况下，也能防止向周围蔓延燃烧。若具有阻燃性，则树脂的种类不作特别限定。
金属制罩部12覆盖壳体部11的外表面。由此，从其他装置/部件类辐射至控制基板侧的电磁波、从控制基板侧辐射至其他装置/部件类的电磁波被屏蔽，期望的电磁兼容性(Electromagnetic Compatibility,以下“EMC”)得以确保。另外，金属制罩部12与阻燃性的壳体部11互相结合，防止例如在控制基板产生的燃烧蔓延。此外，金属制罩部12通过任意的手段接地。它们的细节将后述。
本实施方式中的安装部13是金属制的弯曲板，如图4所示，与弯折后端缘2dr3重叠配置。在安装部13以及弯折后端缘2dr3，分别设置有螺丝插通孔。如图3所示，安装部13与弯折后端缘2dr3通过螺丝131而紧固在一起。由此，安装部13安装固定于弯折后端缘2dr3。
接下来，参照图5来说明本实施方式所涉及的基板收容部10的细节。图5是从壳体部11中分离出金属制罩部12、安装部13等后的状态的概略立体图。在此，壳体部11的一个侧面11s1与外部轮廓侧板2dr对置，并与外部轮廓侧板2dr面对面地相接触或面对面地相接近。另外，壳体部11的另一个侧面11s2也即与所述一个侧面11s1对置的对置面配置于压缩机20等的附近。
如图5所示，本实施方式所涉及的金属制罩部12包括上方罩部12u、侧方罩部12s和后方罩部12r。壳体部上表面11u由上方罩部12u覆盖。另外，壳体部侧面11s2由侧方罩部12s覆盖。进而，壳体部后面(或称背面)11r由后方罩部12r覆盖。
另外，如前所述，壳体部侧面11s1由金属制的外部轮廓侧板2dr1覆盖，且如图3所示，壳体部上表面11u与从隔热箱体后部的弯折基端部2rk弯折的弯折部分2rf1面对面。进而，壳体部底面11b与金属制的压缩机托台21面对面。由此，壳体部11的大部分由金属制的构件覆盖。
现有技术中，除了在壳体部11的侧面11s2，还在侧面11s1侧配置有与图示的金属制罩部12类似的形状的钣金罩，而本实施方式包括即使去除现有技术中配置的钣金罩也能适当确保EMC的结构。如此，根据本实施方式，能减少部件个数，能实现相应量的成本降低。进而，能去除较高价的金属制的部件(所述钣金罩)，因此能更高效地实现产品的成本降低。
如图5所示，优选地，基板收容部10还包括接地用延伸部14。在本实施方式中，金属制罩部12与金属制的安装部13经由接地用延伸部14进行连接。安装部13如前所述，与冰箱外部轮廓侧板的弯折后端缘2dr3重叠接触。因此，金属制罩部12与冰箱外部轮廓还电连接地接地。由此，能发挥金属制罩部12的电磁屏蔽功能。
现有技术中，金属制罩部12与对壳体部11的侧面11s1进行覆盖的所述的钣金罩连接，进而，钣金罩与冰箱1的外部轮廓侧板2dr1电连接。由此，将金属制罩部12接地，但根据本实施方式，即使不是具有这样宽面积的钣金罩，也能将金属制罩部12接地。其结果 是，能实现产品的成本降低。
关于接地用延伸部14的形态，只要能将金属制罩部12接地，就不特别限定，但例如考虑图5所示那样的形态。更具体而言，作为接地用延伸部14，例示了具备配置于壳体部上表面11u侧的上部片14u、配置于壳体部侧面11s1侧的侧部片14s、以及配置于壳体部后面11r侧的后部片14r的形态。
上部片14u设置为与壳体部上表面11u面对面地相接触，其一端侧与金属制罩部12连接。另外，上部片14u的另一端侧与侧部片14s的一端侧连接。侧部片14s设置为从上部片14u的另一端侧向下方侧垂下，且与壳体部侧面11s1面对面地相接触。另外，侧部片14s以呈L字形状的方式朝冰箱后方大致垂直地弯折。与L字的前端对应的侧部片14s的另一端侧与后部片14r连接。后部片14r设置为与安装部13面对面地相接触。由此，金属制罩部12与安装部13(以及与安装部13连接的冰箱1的外部轮廓侧板2dr1)电连接。
以上详细说明了本发明的实施方式。其中，前述说明是为了使本发明的理解容易，并不是以限定本发明的主旨来进行记载的。在本发明中，在不脱离其主旨的前提下，还能够包含可经变更、改良而得到的产物。另外，本发明包含其等效物。
