Description

制冷电器 技术领域
本发明涉及制冷电器，特别地涉及在机械室中收纳构成冷冻循环的压缩机的制冷电器。
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，以使得其成为对所储藏的被储藏物进行冷却保存而优选的温度范围。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中记载了一种制冷电器，压缩机和冷凝器配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，形成机械室，在该机械室的内部，配置压缩机和冷凝器。此外，在压缩机和冷凝器之间配置送风机。在冷冻循环运转时，送风机向冷凝器送风，由此，能够积极地进行冷凝器中的热交换，从而能够使冷冻循环高效地运转。
现有技术文献，专利文献1：日本特开2015-1344号公报。

具体而言，作为将压缩机安装于机械室底部的构造，存在经由螺钉等紧固单元将压缩机的脚部的四角固定于机械室底部的构造。然而，在机械室的里侧进行螺钉紧固作业并不容易，因此，存在将压缩机安装于机械室时的作业效率降低的问题。
此外，还有一种固定结构，为了使压缩机的安装作业简略化而仅将压缩机的脚部的两个相对角部经由螺钉等紧固单元固定于机械室底部。然而，当仅固定压缩机的脚部的相对两个角部时，难以稳定地将压缩机固定于机械室底部。因此，存在如下的问题：在运转冷冻循环时，压缩机产生振动或噪音。此外，有的情况下，将盖子装配于压缩机侧面，在这样的情况下，还存在如下那样的问题：关于将压缩机的里侧部分固定于机械室底部，安装工序变得复杂。

具体实施方式
以下，基于附图来详细地说明本发明的实施方式的制冷电器10。再有，在说明本实施方式时，原则上对相同的构件使用相同的符号，省略重复的说明。使用上下前后左右各方向来说明本实施方式，但是，上下是指制冷电器10的上下方向，前后是指制冷电器10的前后方向，左右是指从后方观察制冷电器10的情况下的左右。
图1是从后侧上方观察本发明的实施方式的制冷电器10的立体图。制冷电器10具有隔热箱体11、以及形成在隔热箱体11内部的储藏室。作为储藏室，具有冷藏室12、蔬菜室114和冷冻室13。冷藏室12的前方开口被旋转式的隔热门18封闭，蔬菜室114的前方开口被抽出式的隔热门19封闭，冷冻室13的前表面开口被抽出式的隔热门20封闭。
在制冷电器10的后侧最下部，形成有作为空腔的机械室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中未图示内置于机械室14的各结构设备。 在机械室14中形成有朝向后方开口的机械室开口15。机械室开口15可以被盖构件堵塞。
图2是制冷电器10的侧方截面图。参照该图，隔热箱体11由如下部分构成：由被曲折加工为规定形状的钢板构成的外箱111、与外箱111分离的配置在内侧的由合成树脂板构成的内箱112、以及填充在外箱111和内箱112之间的隔热材料113。
在冷冻室13的里侧，分隔形成有冷却室115，在冷却室115中收纳有蒸发器116。在冷却室115上方，形成有送风通道118。在此未图示将在冷却室115中被蒸发器116冷却的空气吹送到送风通道118的冷气送风用风扇。蒸发器116冷却的空气也被吹送到冷冻室13。
在冷却室115内部且蒸发器116下方，配置有除霜加热器117。除霜加热器117是利用通电而发热的加热器，在除霜行程中被通电，由此发热，利用产生的热来使蒸发器116的霜发生融化。由于除霜而产生的除霜水到达参照图3后述的蒸发皿27，通过与高温的压缩冷媒或压缩机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中形成有底板24。底板24由被曲折加工为规定形状的钢板构成。在机械室14内部，配置有压缩机22、端子盖16、电控箱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，例如冷媒管道等。
脚部23一体地安装于压缩机22的底部。脚部23由被曲折加工为规定形状的钢板构成。脚部23的前侧部分、即远离机械室开口15的部分如后述那样经由作为推压单元的推压部261等而固定于底板24。另一方面，脚部23的后侧部分、即与机械室开口15接近的部分经由作为紧固单元的螺钉263而固定于底板24。随后，参照图4和图5等来描述将压缩机22固定于底板24的结构。
端子盖16由被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。
电控箱17被固定于机械室14的左侧，收纳有电控板、压缩机22用的电容器等。
蒸发皿27配置在压缩机22上方，贮存在除霜过程中产生的除霜水。
图4(A)是选取示出压缩机22被安装的部分的立体图，图4(B)示出压缩机22被安装于底板24的部分，是沿图4(A)的A-A切截面线的截面图。
参照图4(A)，脚部23的前方右侧部分由推压部261推压，由此固定于底板24，在脚部23的前方右侧部分和推压部261之间安装有第一防振弹性体251。此外，脚 部23的前方左侧部分由推压部262推压由此固定于底板24，在脚部23的前方左侧部分和推压部262之间安装有推压部262。
此外，脚部23的后方右侧部分通过螺钉263固定于底板24，在脚部23的后方右侧部分和螺钉263之间安装有第三防振弹性体253。虽然在图4(A)中未出现，但是，脚部23的后方左侧部分通过螺钉264固定于底板24，在脚部23的后方左侧部分和螺钉264之间安装有第四防振弹性体254。随后，参照图5来描述螺钉264。
像这样，对脚部23的前侧部分进行推压固定，另一方面，对底板24的后侧部分进行紧固固定，由此，能够经由脚部23的四角来将压缩机22稳定地固定于底板24。进而，能够在制冷电器10的制造工序中，将压缩机22容易地安装于底板24上。
参照图4(B)来说明将脚部23的前方左侧部分固定于底板24的结构。通过对脚部23的前方左侧部分进行开口来形成第二插入孔部282，在第二插入孔部282中嵌入第二防振弹性体252。第二防振弹性体252的下端抵接于底板24的上表面，第二防振弹性体252的上端由推压部262推压。此外，第二防振弹性体252在推压部262的下表面和底板24的上表面之间被轻微压缩。像这样，在底板24和脚部23之间存在第二防振弹性体252，由此，通过第二防振弹性体252来吸收由于压缩机22运转而产生的振动，从而能够抑制该振动传达到底板24。
图5(A)是示出将压缩机22安装于底板24的构造的分解立体图，图5(B)是示出第一防振弹性体251的立体图。
参照图5(A)，将脚部23四角附近开口为大致圆形，由此，在脚部23的前方右侧部分中形成第一插入孔部281，在脚部23的前方左侧部分中形成第二插入孔部282，在脚部23的后方右侧部分中形成第三插入孔部283，在脚部23的后方左侧部分中形成第四插入孔部284。在图5(A)中，在脚部23的前方左侧部分中形成的第二插入孔部282被压缩机22遮挡，未图示。
第一防振弹性体251嵌入于第一插入孔部281中，第二防振弹性体252嵌入于在此未出现在附图中的第二插入孔部282中，第三防振弹性体253嵌入于第三插入孔部283中，第四防振弹性体254嵌入于第四插入孔部284中。
在脚部23前方侧配置的第一防振弹性体251和第二防振弹性体252由推压部261和推压部262推压而被固定。另一方面，在脚部23后方侧配置的第三防振弹性体253通过螺钉263紧固。具体而言，螺钉263贯通第三防振弹性体253的孔部，并与在底板24形成的固定孔部293螺合。螺钉263的头部从上方推压第三防振弹性体253， 由此将第三防振弹性体253固定于底板24。将第四防振弹性体254固定于底板24的结构也是同样的，螺钉264的下端部贯通第四防振弹性体254，与并在底板24形成的固定孔部294螺合。由此，螺钉264的头部对第四防振弹性体254的上表面进行推压。
此外，推压部261和推压部262通过对底板24进行切割竖立来形成。
参照图5(B)来说明第一防振弹性体251的结构。第一防振弹性体251通过将橡胶等弹性材料注塑成为大致圆柱状来制造的。从上方起，第一防振弹性体251具有上方圆柱部32、缩径部31和下方圆柱部30。图5(A)所示的第二防振弹性体252、第三防振弹性体253和第四防振弹性体254也是这样的结构。
当将第一防振弹性体251插入于脚部23的第一插入孔部281时，缩径部31嵌入于第一插入孔部281，上方圆柱部32配置在脚部23的上表面侧，下方圆柱部30配置在脚部23的下表面侧。关于第二防振弹性体252、第三防振弹性体253和第四防振弹性体254也是这样的结构。
图6(A)是示出机械室14及其附近的结构的立体图，图6(B)是示出压缩机22的立体图。
参照图6(A)和图6(B)，底板24被装入到隔热箱体11的机械室14中。此外，脚部23被安装于压缩机22的下部，第一防振弹性体251、第二防振弹性体252、第三防振弹性体253和第四防振弹性体254被安装于脚部23的四角。压缩机22在该状态下装入到机械室14的底板24。
图7(A)、图7(B)和图7(C)是示出将压缩机22装入于底板24的方法的侧方截面图。此外，图7(A)、图7(B)和图7(C)对应于沿图5(A)所示的B-B切截面线的截面图。
参照图7(A)，从机械室开口15侧，将压缩机22插入于机械室14的内部。
接着，参照图7(B)，将固定于脚部23前侧部分的第一防振弹性体251插入到推压部261与底板24的上表面之间。在此，第一防振弹性体251的厚度L10比底板24的上表面与推压部261的下表面之间的距离L11长。因此，当将第一防振弹性体251插入于底板24的上表面与推压部261的下表面之间时，第一防振弹性体251在纵方向上被轻微压缩。利用这样的结构，能够通过推压部261充分地压紧固定第一防振弹性体251。
此外，参照图5(A)，在第一防振弹性体251装入的同时，安装于脚部23前方 左侧的第二防振弹性体252也被插入到底板24的上表面与推压部262的下表面之间。
参照图7(C)，接着，将第三防振弹性体253载置于底板24的上表面，将螺钉263插入于第三防振弹性体253的孔部，使螺钉263的下端与固定孔部293螺合。像这样，由此，第三防振弹性体253在通过螺钉263头部从上部压住的状态下固定于底板24。
此外，参照图5(A)，在第三防振弹性体253固定的同时，也固定第四防振弹性体254。即，使第四防振弹性体254的下表面抵接于底板24的上表面。进而，使螺钉264贯通于第四防振弹性体254，进而，使螺钉264的下端与固定孔部294螺合。像这样，第四防振弹性体254在通过螺钉264头部被压住的状态下固定于底板24的上表面。
利用上述工序，压缩机22被固定于底板24。
通过前述的本实施方式，能够实现以下那样的主要效果。
根据本发明的制冷电器10，经由推压部261和推压部262将压缩机22远离机械室开口15的部分固定于底板24，经由作为紧固单元的螺钉263和螺钉264将接近脚部23的机械室开口15的部分固定于底板24，由此，能够相对于底板24容易地装入压缩机22。进而，压缩机22的脚部23在靠近机械室开口15侧和远离机械室开口15侧这两方被固定于底板24，因此，能够相对于底板24稳定地固定压缩机22。进而，在运转冷冻循环时，虽然朝向前方向的力矩作用于压缩机22，但是，通过将脚部23的前侧部分和后侧部分固定于底板24，从而能够抑制由于该力矩使压缩机22较大地位移或者产生噪音或振动。
进而，通过在脚部23和底板24之间配设第一防振弹性体251等，从而能够用第一防振弹性体251等吸收在制冷电器10的运转时从压缩机22产生的振动，而能够实现制冷电器10的低振动和低噪音。
进而，通过推压部261和推压部262来固定远离机械室开口15的第一防振弹性体251和第二防振弹性体252，通过作为紧固单元的螺钉263和螺钉264来固定与机械室开口15接近的第三防振弹性体253和第四防振弹性体254，由此，能够更稳定地支承压缩机22。
进而，通过切割竖立底板24来形成推压部261和推压部262，从而能够削减制冷电器10所需的部件个数。
本发明不限定于上述实施方式，在其他情况下，能够在不脱离本发明的主旨的 范围内实现各种变更实施。
