冷冻循环系统由压缩机、冷凝器、膨胀装置和蒸发器组成。为了实现高压高温状态的制冷剂与外部空气的热交换，上述冷凝器体积设计较大，并且在隔热箱体的后表面附近或底表面附近形成有弯曲行进的制冷剂配管。
在下面的专利文献1中记载了将压缩机和冷凝器布置在隔热箱体的机械室中的冰箱。具体来说，在隔热箱体的后侧最下部形成机械室，在该机械室的内部布置压缩机和冷凝器。另外，在压缩机和冷凝器之间布置有送风机。在冷冻循环系统工作时，可以通过送风机向冷凝器送风以使得冷凝器处实现效果更好的热交换，保证冷冻循环系统的有效运行。

在上述冰箱中，通常具有大型翅片式冷凝器，因此难以使冰箱进一步小型化。为达成冰箱整体小型化目的，考虑将构成冷冻循环系统的各部件汇集到形成在隔热箱体的后方下部的机械室中。然而，构成冷冻循环系统的冷凝器和压缩机在所述冷冻循环系统运转时会产生大量热能，因此在将冷凝器和压缩机收纳在空间矮小的机械室的情况下，难以使从这些构成部件产生的热量排放到冰箱外部。
此外，在机械室中，除了构成冷冻循环系统的冷凝器和压缩机，还需要收纳蒸发盘等，也难以将这些构成部件紧凑地收纳在机械室中。
鉴于上述情况做出了本发明，本发明的目的是提供能够将构成冷冻循环系统的部件紧凑地收纳在机械室中，并且还能够将这些部件运转时发出的热量进行有效排放的冰箱。

另外，在本发明的冰箱中，其特征在于，所述进气口的开口面积大于所述送风机的风洞 的面积。这样，根据本发明的冰箱，由于增大了进气口的开口面积而确保了送风机的送风量较大，于是增大了微通道冷凝器和压缩机的热交换，并且还能够有效地蒸发存积在蒸发盘中的除霜水。
另外，在本发明的冰箱中，其特征在于，所述排气口的开口面积大于所述送风机的风洞的面积。这样，根据本发明的冰箱，由于增大了排气口的开口面积而确保了送风机的送风量较大，于是增大了微通道冷凝器和压缩机的热交换，并且还能够有效地蒸发存积在蒸发盘中的除霜水。

具体实施方式
在下文中，基于附图来详细说明本发明的实施例所涉及的冰箱10。此外，在说明本实施例时，原则上对同样的构件使用同样的标号，并且省略了重复的说明。本实施例用上下前后左右的各方向来进行说明，左右是从冰箱10的后方来看的情况下的左右。
图1是从后方上方看本发明的实施例所涉及的冰箱10的立体图。冰箱10具有隔热箱体11和形成在隔热箱体11内部的贮藏室。作为贮藏室，有冷藏室12、蔬菜室114和冷冻室13。用旋转式隔热门18封闭冷藏室12的前方开口，用抽屉式隔热门19封闭蔬菜室114的前方开口，并且用抽屉式隔热门20封闭冷冻室13的前面开口。冰箱10的外壳111由朝着上方的顶板151、朝着左方的侧面板152、朝着右方的侧面板153和朝着后方的背面板154构成。
在冰箱10的后侧最下部形成有作为空腔的机械室14。机械室14被形成为从隔热箱体11的左端连接到其右端。另外，用机械室盖部155封住机械室14的后方开口。
在机械室14的右侧形成有用于外部空气进入机械室14的进气口26。所述进气口26为设置在侧面板153和机械室盖部155处的多个开口。另外，在机械室14的左侧形成有用于从机械室14向外部放出的空气通过的排气口27。所述排气口27为设置在侧面板152和机械室盖部155处的多个开口。参照图7详细描述进气口26和排气口27。所述进气口26和排气口27设置为狭缝状，以防止异物从外部侵入到机械室14中。
图2是冰箱10的侧视截面图。参照该图，隔热箱体11由以下各部分构成：外壳111，其由被弯曲加工成指定形状的钢板制成；内胆112，其由设置外壳111内侧且与外壳111分离的合成树脂板制成；以及隔热材料113，其填充在外壳111与内胆112之间。
在冷冻室13的内侧划分形成冷却室115，在冷却室115中收纳有蒸发器116。在冷却室115的上方形成有送风风道118。经所述冷却室115中的蒸发器116冷却后的空气通过冷气送风用的风扇(此处未示出)被送风到送风风道118处。所述蒸发器116冷却的空气还送风到冷冻室13中。
除霜加热器117布置在处于冷却室115内部的蒸发器116的下方。除霜加热器117是通过通电而发热的加热器，其在除霜过程中通电并发热，并通过所产生的热量来融化蒸发器116上的结霜。因除霜而产生的除霜水经过图4所示的导水管31到达蒸发盘25，通过与高温压缩制冷剂进行热交换而被蒸发。
图3是从后侧上方看机械室14内部的立体图。其中示出了从冰箱10拆下上述机械室盖部155的状况。
从右边开始，在机械室14中装有微通道冷凝器23、送风机21、蒸发盘25和压缩机22。另外，在机械室14中还装有制冷剂配管，其用于将构成包括微通道冷凝器23和压缩机22的蒸汽压缩型冷冻循环系统的各部件彼此连接。
像这样，构成冷冻循环系统的各部件与蒸发盘25一起收纳在机械室14中，能够减小为了容纳冰箱10的运转所必需的部件的容积。因此，对于冰箱10整体来说，能够增大贮藏室所占据的有效容积。这样，能够在冰箱10中收纳更多的物品，并且能够减小冰箱10的外形尺寸。
参照图4和图5来说明收纳在上述机械室14中的各部件，同时说明在机械室14的内部的空气流动方向。图4是示出收纳在机械室14中的各部件的立体图，图5(A)是从上方看这些各部件的俯视图，并且图5(B)是从后方看这些各部件的后视图。
参照图4，在机械室14的内部，压缩机22布置在左侧，并且蒸发盘25布置在右侧。压缩机22和蒸发盘25是收纳在机械室14中内的各部件中的体积相对较大的部件。在本实施例中，作为大型部件的压缩机22和蒸发盘25是左右排列地配设的，于是能够有效地活用机械室14的空间。
压缩机22与微通道冷凝器23、未示出的膨胀装置、上述蒸发器116一起构成蒸汽压缩型冷冻循环系统。伴随着利用冷冻循环系统的冷却运转，在蒸发器116的表面处产生结霜。由于在蒸发器116的表面处产生大量结霜会阻碍传热和送风，因此利用除霜加热器17来加热蒸发器116以定期进行除霜。对蒸发器116进行除霜而产生的除霜水经过导水管31而存积在蒸发盘25中，并且利用从制冷剂发出的热量来使所述除霜水蒸发。
送风机21和微通道冷凝器23布置在蒸发盘25的上方。通过这样做，能够有效地利用作为扁平部件的蒸发盘25的上方的空间。
送风机21布置在后文描述的遮挡板28的上表面处。布置在送风机21内部的风扇旋转，从而将空气从右方吹向左方。
微通道冷凝器23是小型冷凝器，并且布置在遮挡板28的上表面处。所述微通道冷凝器23是微通道化的冷凝器，其由传热管(此处未示出)和放热翅片构成。微通道冷凝器23与一般的冷凝器相比能够以较小的体积实现较大的热交换量。微通道冷凝器23布置在遮挡板 28的上表面、比送风机21更右侧(上游侧)处。
蒸发盘25是用于暂时接住上述除霜水的盘形状的构件，其由一体成型的合成树脂制成。具体来说，蒸发盘25具有底面部251、前方侧面部252、后方侧壁部253、左方侧壁部254和右方侧壁部255。另外，导水管31的下端布置在蒸发盘25的底面部251的附近。导水管31是将上述蒸发器116除霜而产生的除霜水引导到蒸发盘25的导管。
在蒸发盘25的上表面侧，从右侧开始，形成有第一开口区域256、封闭区域257和第二开口区域258。第一开口区域256是在右侧的没有封住蒸发盘25的上表面并且向上开放的区域。封闭区域257是通过遮挡板28封住蒸发盘25的上表面的区域。第二开口区域258是在左侧的没有封住蒸发盘25的上表面并且向上开放的区域。像这样在蒸发盘25的上表面处形成第一开口区域256、封闭区域257和第二开口区域258，于是如后文描述的那样，能够形成用于恰当地蒸发存积于蒸发盘25中的除霜水的空气循环路线。
在蒸发盘25的上表面处布置有遮挡板28。遮挡板28由金属板或者树脂板制成，在左右方向上从上方覆盖蒸发盘25的中央部分。遮挡板28的后端侧固定在后方侧壁部253的上端，并且遮挡板28的前端侧固定在前方侧面部252的上端。
在遮挡板28的上表面处从右侧开始布置有微通道冷凝器23和送风机21。遮挡板28部分地封住蒸发盘25的上方，并且用作承载送风机21和微通道冷凝器23的载置台。由金属板制成的支撑板29固定在微通道冷凝器23的下表面处。支撑板29的左端固定在遮挡板28的上表面处。另外，支撑板29的右端固定在从蒸发盘25的底面部251向上方突出的突出支撑部30处。
由于冰箱10运转时送风机21旋转，从图3所示的进气口26导入外部空气，所导入的空气在机械室14处通过微通道冷凝器23、送风机21和压缩机22。此后，空气经过图3所示的排气口27放出到外部。
压缩机22和微通道冷凝器23用制冷剂配管37彼此连接，经压缩机22压缩而被高温化的压缩制冷剂经过制冷剂配管37送到微通道冷凝器23。制冷剂配管37从第二开口区域258开始在蒸发盘25的底面部251附近盘桓，从第一开口区域256向上离开，然后连接微通道冷凝器23。由于制冷剂配管37在蒸发盘25内部盘桓，因此能够通过存积在蒸发盘25中的 除霜水来冷却压缩制冷剂，并促进除霜水的蒸发。后文参照图6来描述关于制冷剂配管37。
参照图5来说明形成在机械室14内部的空气路线。图5(A)是从上方看装在机械室14内的各构成部件的俯视图，并且图5(B)是从后方看这些各部件的后视图。
参照图5(A)和图5(B)，在通过送风机21进行送风时，在机械室14的内部形成了空气通过路线35和空气循环路线36。
空气通过路线35是空气在机械室14的内部从右向左吹过的路线。具体来说，空气通过路线35是从图3所示的进气口26进入的空气按微通道冷凝器23、送风机21和压缩机22的顺序通过并从图3所示的排气口27放出到外部的路线。由于形成了空气通过路线35，促进了微通道冷凝器23和压缩机22处的热交换，使制冷剂在微通道冷凝器23中良好地冷凝，并且较好地冷却了压缩机22。
空气循环路线36是空气在机械室14的内部循环的路线。具体来说，对于空气循环路线36，空气首先按微通道冷凝器23和送风机21的顺序通过。接下来，通过送风机21的空气的一部分被蒸发盘25的左方侧壁部254挡住，并从第二开口区域258进入到蒸发盘25的内部。进入到蒸发盘25的内部的空气在遮挡板28的下方、沿着除霜水的液面附近向右前进。此时促进了除霜水的蒸发。在图5(B)中，除霜水的液面用点划线示出。此后，进一步向右前进的空气被右方侧壁部255挡住，经过第一开口区域256向上前进，然后回到微通道冷凝器23和送风机21处。
由于空气按空气循环路线36来循环，因此与微通道冷凝器23进行热交换而变得高温的空气通过存积在蒸发盘25中的除霜水的上表面并与之进行热交换，于是能够促进除霜水的蒸发。此外，在蒸发盘25内部蒸发除霜水而得以冷却的空气从第一开口区域256返回并通过微通道冷凝器23。藉此，促进了微通道冷凝器23处的热交换，并且能够有效地冷凝制冷剂。另外，由于在空气循环路线36中循环的空气的一部分经过空气通过路线35放出到外部，因此蒸发的除霜水不会充满机械室14的内部。
另外，由于藉由形成了空气通过路线35而能够一直从进气口26将干燥的低温空气从外部导入到机械室14，因此能够促进微通道冷凝器23的热交换和除霜水的蒸发。由于藉由形成了空气通过路线35而能够一直将空气经过排气口27放出到外部，因此能够抑制通过微通 道冷凝器23和压缩机22的热交换而被加热的空气充满机械室14。
此处，空气通过路线35和空气循环路线36不是完全分离的路线，而是空气在空气通过路线35和空气循环路线36中混在一起。换言之，构成空气通过路线35的空气导入到空气循环路线36中，于是能够使用从外部供给的干燥空气来良好地蒸发除霜水。此外，构成空气循环路线36的空气导入到空气通过路线35中，于是能够从机械室14向外部良好地放出从微通道冷凝器23产生的热量和因除霜水的蒸发而产生的水分。
此处，将说明用于改善上述空气循环路线36中的空气流动的构造。
参照图5(A)，第一开口区域256、封闭区域257和第二开口区域258的相对大小可以设置成用于形成空气循环路线36的恰当范围。例如，可以使第一开口区域256和第二开口区域258的各自的开口面积比封闭区域257更大。通过这样做，通过第一开口区域256和第二开口区域258的空气的流量增大，并且能够促进微通道冷凝器23的热交换和除霜水的蒸发。
参照图5(B)，蒸发盘25的左方侧壁部254的上端P2布置在送风机21的下端P1的下方。通过这样做，可在以挡住用送风机21送风的一部分空气的方式形成空气通过路线35的同时，防止存积在蒸发盘25中的除霜水到达送风机21处。
参照图6来说明蒸发盘25和制冷剂配管37的关联构造。图6是从上方看收纳在上述机械室14中的各构成部件的立体图。
如上所述，蒸发盘25邻接在压缩机22的右侧。另外，压缩后的制冷剂在其中流通的制冷剂配管37从压缩机22导出。制冷剂配管37被形成为越过蒸发盘25的左方侧壁部254的上方、沿着底面部251弯曲行进。此外，在底面部251的上表面弯曲行进地形成的制冷剂配管37的多处布置有隔离物38。由于布置了隔离物38，因此制冷剂配管37和底面部251可以分离指定的距离。因此，能够确保存积在蒸发盘25中的除霜水与制冷剂配管37的接触面积较大，在制冷剂配管37的内部流通的高温制冷剂与除霜水有效地进行热交换，并且良好地蒸发除霜水。
参照图7，关于进气口26和排气口27的开口面积进行说明。图7(A)是从左侧看冰箱10的下端部的立体图，图7(B)是从右侧看冰箱10的下端部的立体图，并且图7(C) 是详细示出送风机21的立体图。
参照图7(A)，排气口27形成在机械室14的左端侧，是从机械室14向外部排出空气所通过的开口。排气口27由第一排气口271、第二排气口272和第三排气口273构成。第一排气口271设置在侧面板152的后方下端附近开口的部位。第二排气口272设置在机械室盖部155的左端部分开口的部位。第三排气口273设置在机械室盖部155的上部左侧开口的部位。第一排气口271、第二排气口272和第三排气口273是由行状或列状布置的多个开口构成的。
参照图7(B)，进气口26是形成在机械室14的右端侧的开口，导入到机械室14中的空气通过进气口26。进气口26具有第一进气口261和第二进气口262。第一进气口261是通过在侧面板153的下端后方的部分开口而形成的。第二进气口262是通过在机械室盖部155的右端侧开口而形成的。第一进气口261和第二进气口262是由行状或列状布置的多个开口构成的。
参照图7(C)，送风机21是轴流风扇，其壳体211内部形成有风洞212。当此处未示出的风扇在风洞212的内部旋转时，送风机21将空气从右侧向左侧送风。
在本实施例中，排气口27的开口面积A1被设置为比送风机21的风洞212的开口面积A3更大。具体来说，图7(A)所示的排气口27的开口面积A1是由第一排气口271的开口面积A11、第二排气口272的开口面积A12和第三排气口273的开口面积A13之和算出的。此处，使排气口27的开口面积A1比图7(C)所示的风洞212的开口面积A3更大。通过这样做，能够良好地经过排气口27从机械室14向外部放出空气，并且能够良好地冷却收纳在机械室14中的微通道冷凝器23和压缩机22。
在本实施例中，进气口26的开口面积A2被设置为比送风机21的风洞212的开口面积A3更大。具体来说，图7(B)所示的进气口26的开口面积A2是由第一进气口261的开口面积A21和第二进气口262的开口面积A22之和算出的。将进气口26的开口面积A2设定成比图7(C)所示的风洞212的开口面积A3更大。通过这样做，能够良好地经过进气口26将空气导入到机械室14中，并且能够恰当地冷却收纳在机械室14中的微通道冷凝器23和压缩机22。
参照图8的框图来说明具有上述构造的冰箱10的连接结构。冰箱10具有运算控制部24、温度传感器32、计时器33、压缩机22、送风机21和除霜加热器34。
运算控制部24由例如CPU构成，接收来自各种传感器的输入并进行指定的运算处理，基于其处理结果来控制压缩机22等的各种构成部件的动作。另外，运算控制部24可以具有半导体存储装置，其用于存储用于进行冷却运转的各种常数和程序。通过运算控制部24，各贮藏室实现用于保存被贮藏物的适宜温度范围，并且在适当的时机进行除霜过程。
运算控制部24的输入端连接有温度传感器32和计时器33。温度传感器32通过安装在上述各贮藏室中来测量这些各贮藏室的内部温度。计时器33测量冷却各贮藏室的冷却时间和除霜加热器34的运转时间等。
运算控制部24的输出端连接有压缩机22、送风机21和除霜加热器34。压缩机22等各部件基于从运算控制部24输出的输出信号来进行动作。
在冰箱10的冷却运转时，运算控制部24使压缩机22和送风机21运转，并使用温度传感器32测量各贮藏库的温度达到指定的温度范围。经包括压缩机22的蒸汽压缩型冷冻循环系统冷却的空气被送风到各贮藏室，从而将各贮藏室冷却到指定的温度范围。另外，在压缩机22运转期间，通过送风机21的送风来冷却微通道冷凝器23和压缩机22。
在本实施例中，如上文参照图5描述的那样，在机械室14内部形成空气通过路线35和空气循环路线36，于是能够促进微通道冷凝器23等处的热交换，并且能够良好地蒸发除霜水。
另外，在蒸发器116处的结霜达到一定程度以上时，进行除霜过程以融化在蒸发器116处生长的霜。例如在用计时器33测量的冷却时间达到一定时间时检测蒸发器116处的结霜。另外，因霜的融化而产生的除霜水经过图4所示的导水管31而存积在蒸发盘25中。在本实施例中，如上文参照图5描述的那样，由于形成了空气在蒸发盘25和微通道冷凝器23之间进行循环的空气循环路线36，因此能够利用来自微通道冷凝器23的放热来有效地蒸发除霜水。
本发明不限于上述实施例，此外，在不脱离本发明的要旨的范围内，可以有各种各样的实施变型。
例如，在参照图4的本实施例中，从右侧开始按微通道冷凝器23和送风机21的顺序配设，但是也可以颠倒该顺序，从右侧开始按送风机21和微通道冷凝器23的顺序配设。
