Description

制冷电器 技术领域
本发明涉及一种制冷电器，特别地，涉及一种电箱被安置在机械室中的制冷电器。
背景技术
在一般的制冷电器中，在隔热箱体的内部形成冷藏室等储藏室，该储藏室通过冷冻循环进行冷却，以提供一个合适的温度范围来冷却和保存被储藏物。冷冻循环由压缩机、冷凝器、膨胀单元和蒸发器构成。
在以下的专利文献1：日本特开2015-1344号公报，其记载了一种制冷电器，其构成冷冻循环的设备布置在隔热箱体的机械室中。具体而言，在隔热箱体的后侧最下部形成了机械室，在该机械室的内部配置了压缩机和冷凝器。此外，在压缩机和冷凝器之间配置了送风机。在冷冻循环运转时，送风机向冷凝器送风，由此，能够使得冷凝器中的热交换积极地进行，从而能够使冷冻循环有效地运转。
图7是示出背景技术所涉及的制冷电器100的图，图7(A)是从后侧上方观察机械室102的立体图，图7(B)是从后侧下方观察电箱105被连接之处的立体图。
参照图7(A)，在制冷电器100的隔热箱体101的后方下端，划分并形成了机械室102。在机械室102中收纳冷冻循环的结构设备，在此，仅图示了压缩机103和电箱105。电箱105包括例如控制基板，所述控制基板具有用于对冷冻循环进行控制的控制电路。
参照图7(B)，电箱105的左端通过螺钉106固定到外箱侧面107的后侧。通过这样的结构，规定了电箱105在机械室102内部的位置。
发明要解决的问题
然而，在上述的制冷电器中，关于对电箱105进行固定的构造，存在改善的余地。
参照图8，说明背景技术所涉及的制冷电器100的问题。图8(A)是电箱105被连接之处的上方截面图，图8(B)是示出电箱105进行位移的状况的上方截面图。再有，在图8(A)和图8(B)中，用虚线示出了外箱后表面104。
参照图8(A)，电箱105的左端通过螺钉106固定到外箱侧面107的后侧边。此外，在电箱105和外箱侧面107之间配置了制冷剂管道108。
在此，在制冷电器10的制造工序中，存在如下的作业，即：将制冷剂管道108的一端从机械室102抽出到外部，对制冷剂管道108进行焊接，之后，使制冷剂管道108再次回到机械室102。此时，当制冷剂管道108未回到规定位置时，制冷剂管道108可能会挤压电箱105。
参照图8(B)，制冷剂管道108未回到规定位置，由此，当制冷剂管道108向右方挤压电箱105时，电箱105以如下的方式发生位移，即：将由螺钉106固定之处作为中心进行旋转。这样，电箱105的一部分将从外箱后表面104向后方突出。当电箱105从外箱后表面104突出时，在制冷电器100的使用状况下，存在如下的担忧，即：水顺着外箱后表面104的外表面流动，可能会弄湿电箱105，使在电箱105中收纳的电气电路发生短路。
此外，当电箱105被在此未图示的电源线、线束等拉拽时，如图8(B)所示，电箱105可能被不经意地位移到外箱后表面104内部。
发明内容
本发明鉴于上述的情况而完成，其目的在于，提供一种制冷电器，其能够以简易的结构来抑制电箱在机械室内部的位移。
用于解决问题的方案

此外，在本发明的制冷电器中，所述连接部配置在所述电箱的一端侧，所述突出插入部配置在所述电箱的与所述连接部相对的端部侧。因此，根据本申请发明的制冷电器，能够将突出插入部配置在远离连接部的位置处，从而能够使利用突出插入部来抑制电箱的移动的效果变得显著。
此外，在本发明的制冷电器中，在所述机械室的内部，在所述电箱的附近配置有制冷剂管道，所述突出插入部配置在所述电箱远离所述制冷剂管道的侧的端部。因此，根据本申请发明的制冷电器，即使电箱被制冷剂管道挤压，通过在远离制冷剂管道的位置处，将突出插入部插入到开口部，从而也能够抑制电箱的移动。
此外，在本发明的制冷电器中，所述隔热箱体具有外箱、内箱、以及填充于所述外箱和所述内箱之间的隔热材料，所述突出插入部的前端部嵌入设置于所述隔热材料中。因此，根据本申请发明的制冷电器，通过将突出插入部的前端部嵌入设置于隔热材料中，能够将突出插入部强固地固定到隔热箱体侧，从而能够使支承电箱的效果变得显著。

具体实施方式
以下，将基于附图来详细说明本发明的实施方式所涉及的制冷电器10。再有，在说明本实施方式时，原则上对同一构件使用相同的符号，省略重复的说明。在本实施方式中，使用上下前后左右的各方向来进行说明，左右是指从后方观察制冷电器10的情况下的左右。此外，在本实施方式中，作为制冷电器10，例示了具有冷冻室和冷藏室的制冷电器，但是，制冷电器10也可以是仅具有冷冻室或仅具有冷藏室的制冷电器。
图1是从后侧上方观察本发明的实施方式所涉及的制冷电器10的立体图。制冷电器10具有：隔热箱体11、以及在隔热箱体11内部形成的 储藏室。作为储藏室，具有冷藏室12、蔬菜室114和冷冻室13。冷藏室12的前方开口通过旋转式的隔热门18封闭，蔬菜室114的前方开口通过抽出式的隔热门19封闭，冷冻室13的前表面开口通过抽出式的隔热门20封闭。
在制冷电器10的后侧的底部，形成了作为空腔的机械室14。机械室14从隔热箱体11的左端到右端连续地形成。在图1中，未图示在机械室14中内置的各结构设备。在机械室14中形成了朝向后方开口的机械室开口15。机械室开口15也可以被盖子堵塞。
图2是制冷电器10的侧方截面图。参照该图，隔热箱体11由外箱111、内箱112和隔热材料113构成，所述外箱111由钢板被曲折加工为规定形状构成，所述内箱112由与外箱111间隔设置且在外箱111内侧的合成树脂板构成，所述隔热材料113填充于外箱111和内箱112之间。
在冷冻室13的内侧划分并形成了冷却室115，在冷却室115中收纳了蒸发器116。在冷却室115的上方形成了送风路118。通过在此未图示的冷气吹送用风扇将空气吹送到送风路118，所述空气在冷却室115中被蒸发器116冷却。蒸发器116所冷却的空气也被吹送到冷冻室13。
在冷却室115内部配置了除霜加热器117，除霜加热器117位于蒸发器116下方。除霜加热器117是由于通电而发热的加热器，在除霜行程中被通电时发热，通过所产生的热来熔融蒸发器116的霜。由于除霜而产生的除霜水到达参照图3而后述的蒸发皿27，通过与高温的压缩制冷剂或压缩机22进行热交换而蒸发。
图3是从后侧上方观察机械室14的立体图。在机械室14内部，配置了压缩机22、端子盖16、电箱17和蒸发皿27。在图3中，未图示在机械室14中收纳的其他构件，例如制冷剂管道等。
端子盖16由成形为规定形状的合成树脂板构成，配置在压缩机22的左侧，覆盖在压缩机22中形成的各电极。
电箱17被固定到机械室14的左侧面，收纳了控制板、压缩机22用的电容器等。
蒸发皿27配置在压缩机22的上方，用以贮存在除霜行程中产生的除霜水。
图4(A)是详细示出电箱17的结构的分解立体图，图4(B)是示出电箱17的基板固定夹具173的结构的立体图。
参照图4(A)，电箱17具有基板壳体171、基板172和基板固定夹具173。
基板壳体171和基板固定夹具173由射出成形的合成树脂或金属板构成，通过将基板壳体171和基板固定夹具173彼此卡合，来构成盒子形状。基板172被放置在基板壳体171和基板固定夹具173的内部。
基板172由例如玻璃环氧树脂基板等构成，形成有电气电路，所述电气电路用于对构成冷冻循环的各设备进行控制。在基板172的表面，例如安装了电容器等电路元件。
基板固定夹具173的左侧通过螺钉175固定到机械室14的侧面。具体而言，基板固定夹具173的左侧固定到外箱侧面23的后侧，其构成机械室14的内壁。此外，基板固定夹具173插入螺钉175的部分通过基板支架174来增强。
参照图4(B)，通过使基板固定夹具173的后上方端部朝向上方突出来形成突出插入部25。突出插入部25例如与射出成形的基板固定夹具173的主体部分一体成型。此外，突出插入部25具有尖锐部251和肋状物252。尖锐部251是使突出插入部25的上端尖锐地成型的部位。通过具有尖锐部251，能够如之后说明的那样容易地将突出插入部25的前端部插入到隔热材料113。此外，肋状物252是突出插入部25的左右方向两端部变厚的部位。肋状物252从突出插入部25的下端到上端附近连续地形成。通过形成肋状物252，能够增强突出插入部25，从而能够防 止突出插入部25在向突出插入部25作用外力时的破损或变形。
图5(A)是从前方观察突出插入部25被插入到开口部26的结构的立体图，图5(B)是从后方观察突出插入部25被插入到开口部26的结构的立体图。
参照图5(A)，在机械室14的上表面形成了上表面构件24。上表面构件24由形成为规定形状的钢板构成，构成了图2所示的外箱111的一部分。
通过使上表面构件24的一部分呈大致矩形地开口，从而形成了开口部26。突出插入部25从下方插入到开口部26。突出插入部25从开口部26朝向上方突出的部分被嵌入设置于图2所示的隔热材料113中。
参照图5(B)，电箱17的左端部通过连接部29固定到外箱侧面23的侧面，其形成了机械室14的左侧面。此外，突出插入部25被插入到开口部26，所述突出插入部25形成在电箱17的右侧端部。这样，电箱17的宽度方向上的两端部被固定到隔热箱体11，因此，能够抑制电箱17在机械室14内部进行移动。
图6(A)是详细示出电箱17被连接的结构的立体图，图6(B)是示出电箱17被连接的结构的上方截面图。
参照图6(B)，制冷剂管道28放置在电箱17和外箱侧面23之间。制冷剂管道28是在冷冻循环中使用的制冷剂所流通的、由铜等金属构成的管道。
如前所述，在制冷电器10的制造工序中，存在如下的作业，即：将制冷剂管道28从机械室14拉出到外部，进行焊接，之后，使制冷剂管道28再次回到机械室14。此时，制冷剂管道28有时偏离正常的位置。在此，示出了制冷剂管道28偏离正常的位置并且其后方部分配置在右侧的情况。在该情况下，由制冷剂管道28的后端朝向左方挤压电箱17的后方部分。
在本实施方式中，如图6(A)所示，电箱17的左侧端部通过2个螺钉175而固定到外箱侧面23。此外，在电箱17的右侧端部，突出插入部25被插入到开口部26。进而，如图6(B)所示，制冷剂管道28配置在电箱17的右方，而突出插入部25形成在电箱17的左侧。
这样，电箱17被牢固地固定到隔热箱体11侧，因此，即使错误配置的制冷剂管道28挤压电箱17，也抑制电箱17移动。因此，能够防止电箱17的任何一部分冒出到外箱后表面21的外侧。
利用前述的实施方式，能够实现以下那样的主要效果。
根据本实施方式，通过将突出插入部25插入到开口部26，从而能够抑制电箱17在机械室14内部不经意地移动，所述突出插入部25是通过将电箱17的一部分成形为突起状来设置的，所述开口部26形成在机械室14的内面。
进而，将突出插入部25配置在远离连接部29的位置处，能够使利用突出插入部25来抑制电箱17的移动的效果变得显著。
进而，即使电箱17被制冷剂管道28挤压，通过在远离制冷剂管道28的位置处，将突出插入部25插入到开口部26，从而能够抑制电箱17的移动。
另外，通过将突出插入部25的前端部嵌入到隔热材料113中，能够将突出插入部25牢固地固定到隔热箱体11侧，从而能够使支承电箱17的效果变得显著。
本发明不限定于上述实施方式，此外，能够在不脱离本发明的主旨的范围内进行各种变更实施。
