Description

冰箱 技术领域
本发明涉及一种具有蒸发器的冰箱。
背景技术
具有蒸发器的冰箱被广泛使用。在具有蒸发器的冰箱中，冰箱内的气体通过风扇而流动，流动的气体在通过蒸发器时被冷却。在这样的冰箱中，提出了具有如下s所述的蒸发器的冰箱，即：所述蒸发器在平板状的主体上安装有热交换管(例如，参照专利文献1：日本特开2010-43828公报)。在专利文献1所记载的冰箱中，将专用的固定构件插入到蒸发器和冰箱的内箱来进行固定。由此，能够容易地进行蒸发器的安装。
但是，在专利文献1所记载的冰箱中，在将蒸发器安装于内箱时，作业者需要在抬起蒸发器的状态下对蒸发器进行定位，并将固定构件插入到蒸发器和内箱中。由于蒸发器具有相当大的重量，因此蒸发器的安装作业成为困难的作业。此外，还存在如下的担忧：由于蒸发器的重量而使抬起的蒸发器的位置发生偏移，固定构件没有被正确插入。
发明内容
本发明的目的在于解决上述问题，提供一种能够以高效的作业来适当地安装蒸发器的冰箱。
本发明的冰箱的特征在于，具有：
蒸发器，具有一边左右折回一边上下延伸的热交换管、以及在左右两侧的折回区域中支承所述热交换管的支承构件；以及
接水面，配置在所述蒸发器的下侧，接受从所述蒸发器落下的液体，
所述支承构件比所述热交换管更向下侧延伸，所述支承构件的下端与所述接水面相接。
在本发明中，关于蒸发器的支承构件，由于支承构件比热交换管更向下侧延伸，支承构件的下端与接水面相接，所以能够将蒸发器载置在接水面上。由此，在将蒸发器安装在冰箱的内箱的内表面等上时，作业者能够在不抬起蒸发器的情况下进行定位并进行螺钉固定。由此，能够将紧固螺钉笔直地插入螺钉孔并紧固。因此，能 够以高效的作业将蒸发器适当地安装在冰箱上。
此外，在本发明的冰箱中，其特征在于，
在所述接水面中开口有排水孔，所述排水孔将从所述蒸发器落下的液体向外部排出，
在所述支承构件的下部孔具有通液孔。
由于支承构件的下端与接水面相接，所以落在接水面上的液体的流动有可能被支承构件阻止，但是，在本发明中，由于在支承构件的下部具有通液孔，所以落在接水面上的液体能够通过通液孔流动。由此，能够将落在接水面上的液体可靠地经由排水孔向外部排出。
此外，在本发明的冰箱中，其特征在于，
在所述热交换管的下侧且所述接露面的上侧具有左右延伸的除霜加热器，线束从所述除霜加热器的至少一个端部向外部延伸，
还具有约束构件，所述约束构件是通过所述通液孔中的细长部件成为圈状的构件，通过该圈中的所述线束与所述细长部件相接，
从所述除霜加热器向外部出来的所述线束被所述约束构件约束而向下侧延伸。
在本发明中，从除霜加热器向外部出来的线束被约束构件约束而向下侧延伸。假设即使在线束被向上侧拉伸的情况下，也由于线束和细长部件之间存在摩擦，所以能够经由通过通液孔的约束构件，由蒸发器的支承构件承受向上侧拉伸的力。因此，能够防止对线束的与除霜加热器的边界部分施加过大的力。因此，能够防止线束和除霜加热器的发热体发生断线。
此外，即使在由除霜所产生的液体溅上线束的情况下，也能够防止液体流入到其中线束向外部出来的除霜加热器的端部。因此，能够防止线束、除霜加热器的发热体发生短路。由此，能够提供具有可靠性高的除霜加热器的冰箱，其适当地保护线束和除霜加热器。
此外，在本发明的冰箱中，其特征在于，从所述除霜加热器向下侧延伸的所述线束在与所述约束构件相接的区域中弯曲并向上侧延伸，在所述蒸发器的左右方向的端部附近进一步向上侧延伸。
在本发明中，假设即使在线束被向上侧拉伸的情况下，也能够在与约束构件相接的线束的弯曲的区域中可靠地承受力，从而防止对线束的与除霜加热器的边界部分施加力。此外，即使在由除霜所产生的液体溅上除霜加热器的线束的情况下，也能够使液体从线束弯曲的区域流向约束构件。通过约束构件向下侧流动的液体流过 接露面，经由排水孔向外部排出。由此，能够可靠地保护线束和除霜加热器，将溅上线束的液体可靠地向外部排出。
此外，在本发明的冰箱中，其特征在于，在所述蒸发器和所述端部附近向上侧延伸的所述线束被流道外壳覆盖，所述流道外壳形成冷却流路。
如上所述，由于能够以不对线束的与除霜加热器的连接区域施加力的方式，将线束向上侧拉伸，所以线束不会向蒸发器的外侧鼓起。因此，在将流道外壳安装在冰箱的内箱等上时，能够防止流道外壳夹住线束。由此，能够实现高效的流道外壳的安装。
如上所述，在本发明中，能够提供一种能够以高效的作业来适当地安装蒸发器的冰箱。

(一个实施方式的冰箱)
图1是示意性地示出本发明一个实施方式的冰箱2的侧面剖视图。图2是示意性地示出具有风扇16的流道外壳8以覆盖蒸发器20的方式安装在内箱6的内表面6A上的时候的立体图。图3是示出本发明一个实施方式的蒸发器20的侧视图。首先， 参照并使用图1至图3来说明本发明一个实施方式的冰箱2的概要。
在图1中，用虚线箭头示出了冰箱2的储藏区域4内的气体的流动。冰箱2在内箱6的内侧，具有用于冷藏或冷冻食品的储藏区域4。在内箱6和外箱2B之间配置有隔热材料。即，储藏区域4的周围被隔热材料包围。在冰箱2的前表面侧，开闭自由地安装有门2A，能够对门2A开闭来进行食品从储藏区域4的存取。在冰箱2的后侧的下部具有机器室12，该机器室12配置有压缩机、冷凝器等。
蒸发器20隔着流道外壳8配置在储藏区域4的后侧，所述蒸发器20对储藏区域4内的气体进行冷却。如图2所示，流道外壳8具有前面板和其两侧的侧面板。流道外壳8以覆盖蒸发器20的方式安装在冰箱2的内箱6的内表面6A上。配置有蒸发器20并被流道外壳8覆盖的区域成为冷却流路10。在冷却流路10的蒸发器20的上侧配置有风扇16，该风扇16使冷却流路10内的气体流动。风扇16安装在流道外壳8。在流道外壳8的前面板中设置有开口8A，该开口8A使由风扇16流动的气体从冷却流路10流入到储藏区域4。
如图1的虚线箭头所示，气体从流道外壳8的下侧的开口流入到由流道外壳8划定的冷却流路10。气体进一步向上流动，通过蒸发器20，在此期间被冷却。由蒸发器20冷却后的气体通过风扇16从设于流道外壳8的开口8A吹出到食品的储藏区域4。吹出的气体在储藏区域4内循环，对储藏的食品进行冷却。然后，气体再次从流道外壳8的下侧的开口流入到由流道外壳8划定的冷却流路10。通过重复该循环，储藏区域4作为冷藏室或冷冻室发挥功能。
如图3所示，蒸发器20具有左右折回且上下延伸的热交换管26，在热交换管26上安装有沿上下方向延伸的多个冷却片28。热交换管26从位于蒸发器20上侧的入口左右曲折(meander)地向下侧延伸，从最下点再次左右曲折地向上返回，到达位于蒸发器20上侧的出口。在热交换管26的左右两侧的折回区域中安装有支承构件22。热交换管26和冷却片28由左右两侧的支承构件22支承。
当气体在冷却片28之间的空间从下向上流动时，通过与热交换管26的热交换而被冷却，在所述热交换管26的内部流动有制冷剂。因此，在蒸发器20的热交换管26的表面附着有霜，所述霜是由冷却的气体中含有的水分所冷凝的。如果大量的霜附着在热交换管26上，则冷却性能下降，因此定期地需要蒸发器20的除霜。因此，在蒸发器20的下侧配置有左右延伸的除霜加热器40。通过来自除霜加热器40的放射传热、以及周围的气体被加热而上升的对流传热，能够对热交换管26进行加热而进行除霜，所述除霜加热器40配置在蒸发器20下侧。
由于除霜而从蒸发器20落下的液体落下到接水面30上，所述接水面30配置在蒸发器20下方。落下到接水面30的液体流过接水面30，流入到在接水面30开口的排水孔30A。流入排水孔30A的液体经由排出管34流入配置在机器室12内的蒸发皿14。在接水面30上，设置有若干坡度以使落下的液体顺畅地流入排水孔30A。在图3中，排水孔30A配置在蒸发器20的宽度方向的大致中央的区域的下侧，但并不限于此。例如，排水孔30A也可以配置在蒸发器20的宽度方向的端部区域的下侧。
在图1中，为了简单，示出了冰箱2具有作为冷藏室或冷冻室发挥功能的一体的储藏区域4，但并不限于此。例如，也可以是，储藏区域4被划分为多个室间，各自作为冷藏室或冷冻室发挥功能。在该情况下，既可以共用一个蒸发器20，也可以按各个冷藏室、冷冻室中的每个来具有蒸发器20。
(本发明的一个实施方式的蒸发器)
图4是示出蒸发器20的支承构件22的下端与接水面30相接的状态的立体图。图5是示出从除霜加热器40出来的线束42被约束构件50约束而向下侧延伸的状态的立体图。接着，参照图2至图5，对本发明的一个实施方式的蒸发器20和其周边的设备进行说明。
在现有的蒸发器中，例如，当蒸发器通过螺钉固定安装在冰箱的内箱上时，作业者需要在抬起蒸发器的状态下将蒸发器螺钉固定在内箱上。由于蒸发器具有相当大的重量，因此蒸发器的安装作业成为困难的作业。此外，还存在如下的担忧：由于蒸发器的重量而使抬起的蒸发器的位置发生偏移，紧固螺钉相对于在内箱上形成的螺钉孔以偏移的状态固定。
另一方面，本实施方式的蒸发器20的支承构件22具有比热交换管26更向下侧延伸的下侧区域22A，支承构件22的下侧区域22A的下端与接水面30相接。即，成为通过支承构件22使蒸发器20载置在接水面30上的状态。
如图3的箭头A所示，在左右两侧的支承构件22的上侧形成有安装区域22B，该安装区域22B开有通过紧固螺钉(紧固构件)的孔。在蒸发器20载置在接水面30上的状态下，安装区域22B的孔的位置与设置在冰箱2的内箱6的内表面6A上的螺钉孔的位置在高度方向上大致一致。因此，通过在蒸发器20载置在接水面30上的状态下，调整蒸发器20的水平方向的位置，能够容易地使安装区域22B的孔的位置与内表面6A的螺钉孔的位置对准。由此，作业者能够在不抬起蒸发器20的情况下，将紧固螺钉(紧固构件)通过安装区域22B的孔，而插入内箱6的螺钉孔中并进行螺钉固定。
如上所述，在本实施方式的冰箱2中，具有蒸发器20和接水面30，所述蒸发器20具有左右折回且上下延伸的热交换管26、以及在左右两侧的折回区域中支承热交换管26的支承构件22，所述接水面30配置在所述蒸发器20的下侧并接受从蒸发器20落下的液体，支承构件22比热交换管26更向下侧延伸，支承构件22(下侧区域22A)的下端与接水面30相接。
因此，能够将蒸发器20载置在接水面30上。由此，在将蒸发器20安装在冰箱2的内箱6的内表面6A上时，作业者能够在不抬起蒸发器20的情况下进行定位并进行螺钉固定。由此，能够将紧固螺钉笔直地插入螺钉孔并紧固。因此，能够以高效的作业将蒸发器20适当地安装在冰箱2上。
如上所述，从蒸发器20落下到接水面30的液体流过接水面30而流入排水孔30A。但是，在支承构件22(下侧区域22A)的下端与接水面30相接的情况下，该液体的流动有可能被支承构件22(下侧区域22A)阻止。因此，在本实施方式的蒸发器20中，在支承构件22(下侧区域22A)的下部具有通液孔24。
落在接水面30上并在接水面30流动的液体能够通过通液孔24流动，所述通液孔24设置在支承构件22(下侧区域22A)的下部。由此，能够将落下到接水面30的液体可靠地经由排水孔32向外部排出。
在本实施方式中，具有如下的形状：在通液孔24下侧有支承构件22的少量构件，但并不限于此。也能够在下侧开口而形成通液孔24。
(蒸发器的线束的处理)
如上所述，在本实施方式中，在蒸发器20的热交换管26的下侧且接水面30的上侧，具有左右延伸的除霜加热器40。除霜加热器40具有细长的圆筒状的石英玻璃管、以及收容在石英玻璃管内部的发热体。此外，线束42从除霜加热器40的左右两侧的端部40A向外部延伸，所述线束42与除霜加热器40的发热体电连接。在本实施方式中，蒸发器20具有呈直线状延伸的石英玻璃管，但不限于此。例如，也可以具有180度折回的呈U字状延伸的石英玻璃管。在该情况下，两个线束从除霜加热器40的一个区域向外部延伸。
从除霜加热器40出来的线束42通过如下那样的空间向上方延伸而与配置在蒸发器20上方的端子44连接：所述空间是在蒸发器20的左右的端部区域即热交换管26折回的弯曲的内侧、且配置在最外侧的冷却片28的外侧。因此，假设线束22处于松弛状态，则线束42有可能向热交换管26的外侧突出。在该情况下，如图2所示，在将流道外壳8安装在内箱6的冰箱2的内箱6的内表面6A上时，突出的线束 42有可能被夹在流道外壳8和内箱6的内表面6A之间。
为了应对这种情况，需要用力F向上方拉线束42(参照图2的力F、虚线的箭头)，以便防止线束42松弛而被流道外壳8夹住。如果拉力F直接施加到线束42的与除霜加热器40的边界区域，所述拉力F克服线束42的刚性而消除松弛，则有可能产生断线等问题。因此，在本实施方式中，使用通过上述通液孔24的圈状的约束构件50，不会对线束42的与除霜加热器40的边界部分施加过大的力。
具体而言，如图5所示，将捆扎带穿过通液孔24中，所述捆扎带捆扎线缆并且带紧固件，此外，以线束42通过其中的方式形成为圈状，用紧固件固定成圈状。由此，形成了约束构件50，其中捆扎带那样的细长部件成为圈状。当使约束构件50的圈变小时，线束42的与约束构件50相接的部分被拉向通液孔24侧。由此，在端部40A从除霜加热器40向外部出来的线束42被约束构件50约束而向下侧延伸。如图5所示，通过将约束构件50的圈设为适当的大小来固定紧固件的位置，从而使线束42成为适当地向下侧延伸的状态。
捆扎带是形成约束构件50的圈的细长部件的一例，并不限于此。只要是能够形成圈的可变形的绳状构件，就能够采用其他任意的部件。
如上所述，在本实施方式的冰箱2中，在热交换管26下侧且接水面30上侧具有左右延伸的除霜加热器40，线束42从除霜加热器40的至少一个端部向外部延伸，还具有约束构件50，所述约束构件50是通过通液孔24中的细长部件(例如捆扎带)成为圈状的构件，通过该圈中的线束42与细长部件相接，从除霜加热器40向外部出来的线束42被约束构件50约束而向下侧延伸。
如上所述，为了防止在热交换管26的弯曲部的内侧向上方延伸的线束42松弛而向热交换管26的弯曲部的外侧突出，需要用某种程度大小的力F向上方拉线束42。在本实施方式中，由于在线束42和构成约束构件50的细长部件之间存在摩擦，所以能够在线束42和约束构件50的细长部件的接触部分处承受向上侧拉伸的力F(参照图5的箭头B、力F)。因此，能够经由通过通液孔24的约束构件50，由蒸发器20的支承构件22承受向上侧拉线束42的力F。由此，能够防止对线束42的与除霜加热器40的边界部分(参照图5的箭头C)施加过大的力。因此，能够防止线束42断线，并且能够防止线束42与除霜加热器40的发热体之间断线。
此外，即使在由除霜所产生的液体溅上线束42的情况下，液体也向位于最低位置的线束42的被约束构件50约束的区域(参照图5的箭头B)流动，能够防止落到线束42的液体流入到其中线束42向外部出来的除霜加热器的端部40A(参照图5的 箭头C)。因此，能够防止线束42、除霜加热器40的发热体发生短路。由此，能够提供具有可靠性高的除霜加热器40的冰箱2，其适当地保护线束42和除霜加热器40。
如图5所示，从除霜加热器40向下侧延伸的线束42在与约束构件50相接的区域中弯曲并向上侧延伸，在蒸发器20的左右方向的端部附近进一步向上侧延伸。
然后，线束42进一步在蒸发器20的热交换管26的弯曲部的内侧向上侧延伸，与配置在蒸发器20上方的端子44连接。在图5中示出了线束42在除霜加热器40的玻璃管的下端附近的位置处弯曲的示例。但是，这是一例，例如也能够使线束42在更下方的位置处弯曲。
通过以上的结构，即使在线束42被向上侧拉伸的情况下，也能够在与约束构件50相接的线束42的弯曲的区域中可靠地承受力，从而防止对线束42的与除霜加热器的边界部分施加力。此外，即使在由除霜所产生的液体溅上线束42的情况下，也能够使液体从线束42的弯曲的区域流向约束构件50。通过约束构件50向下侧流动的液体流过接水面30，经由排水孔32向外部排出。由此，能够可靠地保护线束42和除霜加热器40，可靠地将溅上线束42的液体向外部排出。
此外，如上所述，线束42被流道外壳8覆盖，所述流道外壳8形成冷却流路10，所述线束42在蒸发器20和蒸发器20的端部附近(例如热交换管26的弯曲部的内侧)向上侧延伸。但是，在本实施方式中，能够不对线束42的与除霜加热器的边界部分施加力，将线束42向上侧拉伸。由此，能够可靠地防止线束42向蒸发器20的外侧鼓起。因此，在将流道外壳8安装在冰箱2的内箱6的内表面6A上时，能够防止线束42被夹在流道外壳8和内箱6的内表面6A之间。由此，能够实现高效的流道外壳8的安装。
虽然说明了本发明的实施方式、实施形式，但是公开内容也可以在结构的细节上变化，实施方式、实施形式中的要素的组合、顺序的变化等能够在不脱离所要求保护的本发明的范围和思想的情况下实现。
