Description

冰箱 技术领域
本发明涉及一种冰箱，尤其涉及一种可设置在整体厨房(system kitchen)等中的冰箱。
背景技术
随着整体厨房的普及，在整体厨房内设置的冰箱也实用化。在这样的冰箱中，因为空间有限，所以多使用直冷式，其不具有循环风扇，而利用蒸发器直接冷却食品等收纳物。但是，在直冷式的冰箱中，很难自动除霜，除霜时，需要从内箱取出收纳物。
因此，提出了一种整体厨房用的冰箱，其不是直冷式，而与通常的冰箱同样在背面侧设置有蒸发器和循环风扇。但是，为了设置在整体厨房内，需要缩小冰箱的深度尺寸，因此内箱的深度尺寸也受到制约。在该冰箱中，为了确保蒸发器、循环风扇的设置空间，需要进一步缩小内箱有限的深度尺寸，所以在内箱内的收纳容量方面，产生了问题。
因此，为了确保内箱的深度方向的尺寸，提出了一种冰箱，其将蒸发器和循环风扇配置在上侧的内箱与下侧的内箱之间的空间中(例如，参照专利文献1——日本实开平5-90286号公报)。
然而，在专利文献1中记载的冰箱中，需要在横向配置的蒸发器的下侧整个区域中，配置用于接收除霜时产生的液滴的大的接收皿。为了设置在整体厨房内，冰箱的高度方向的尺寸也需要缩小，因此内箱的高度方向的尺寸也受到制约。在该冰箱中，除了蒸发器之外，为了确保接收皿的设置空间，需要进一步缩小内箱有限的高度尺寸，因此，在内箱内的收纳容量方面，产生了问题。
如上所述，在常规的冰箱(包括引用文献1中记载的冰箱)中，受蒸发器的影响，无法高效地确保内箱内的收纳容量。
发明内容
因此，本发明的目的在于解决上述问题，提供一种冰箱，其能够高效地配置蒸发器以高效地确保内箱内的收纳容量。
本发明的冰箱，包括：
外箱；
第一内箱，设置在所述外箱中，用于收纳物品；
第二内箱，与所述第一内箱并排设置于所述外箱中，所述第二内箱置于所述第一内箱的侧方，用于收纳物品；
风道，设置在并排的所述第一内箱和所述第二内箱之间的空间中；
蒸发器，设置在所述风道内；
循环风扇，设置在所述风道内；
第一上侧开口，设置在所述风道的上侧且与所述第一内箱连通；
第二上侧开口，设置在所述风道的上侧且与所述第二内箱连通；以及
第一下侧开口，设置在所述风道的下侧与所述第一内箱连通；
第二下侧开口，设置在所述风道的下侧与所述第二内箱连通；
所述循环风扇用于使气体在所述风道内从下向上流动，所述气体通过所述蒸发器后，左右分开，经由所述第一上侧开口流入到所述第一内箱，经由所述第二上侧开口流入到所述第二内箱，在每一个内箱内流动后，经由所述第一下侧开口和所述第二下侧开口返回到所述风道，形成冷空气循环。
根据本发明，由于蒸发器被设置在左右并排的内箱之间，所以不会受到内箱的前后方向和上下方向的尺寸的制约。因为蒸发器纵向设置，所以还能够缩小接收皿，所述接收皿接收除霜时产生的液滴。这样，能够高效地配置蒸发器，以高效地确保内箱内的收纳容量。
此外，因为设置有蒸发器的风道被内箱包围，所以能够减少热泄露，获得高的热效率。此外，通过使内箱之间的空间成为风道，能够以非常简单的结构来形成风道。
此外，在本发明的冰箱中，
所述循环风扇设置在所述蒸发器的上方，沿着所述风道向上侧排出气体，排出的气体沿着所述风道的上表面的引导面左右分开，向所述第一上侧开口和所述第二上侧开口流动。
根据本发明，能够利用循环风扇，使气体向上侧排出，沿着风道的上表面的引导面左右分开，经由第一上侧开口和第二上侧开口，流入到第一内箱和第二内箱。由此，能够利用一个循环风扇，高效地向两个内箱内供应冷空气。
此外，在本发明的冰箱中，
在所述第一内箱和所述第二内箱中的至少一个的内部，设置有多个上下划分内部空间的隔板，
所述隔板的内部是中空的，
上侧的所述隔板，在左右方向上的一个的端部设置有连通上下的通风口，下侧的所述搁板，在左右方向上的另一个的端部设置有通风口。
根据本发明，在通过多个隔板来划分内部空间的情况下，隔板的内部是中空的，在上下的隔板中，连通上下的通风口彼此设置在左右相反侧的端部。由此，从上侧开口流入到内箱的气体在内箱内沿着隔板，左右Z字形(zigzag)流动，同时，向下侧流动，因此，能够充分地冷却载置于隔板上的收纳物。
此外，在本发明的冰箱中，
在所述第一内箱和所述第二内箱中的一个内箱的下侧，设置有配置有压缩机的机器室，所述一个内箱的下表面的高度高于另一个内箱的下表面的高度，在所述另一个内箱的下侧，设置有蒸发皿和蒸发冷凝器。
根据本发明，机器室只设置在一个内箱之下，所述机器室设置有压缩机等需要高度的构件，因此，能够在另一个内箱中，确保充分的收纳容量。此外，通过在另一个内箱的下侧的空间中，设置不需要高度的蒸发皿和蒸发冷凝器，能够利用死空间实现高效配置。
此外，在本发明的冰箱中，
在所述机器室中设置有冷却风扇，通过所述冷却风扇，外部空气从前侧流入到所述另一个内箱的下侧，从所述另一个内箱的下侧流向所述一个内箱的下侧的所述机器室，从所述机器室向前侧排出。
根据本发明，从冰箱下部的前侧吸入外部空气，对发热的构件进行冷却，将温度上升的气体从冰箱下部的前侧排出，因此，假设即使在将冰箱设置在整体厨房中的情况下，也能够在不会对周围的构件产生热影响的情况下，实现高效的冷却。
如上所述，在本发明中，能够提供一种冰箱，其能够高效地设置蒸发器以高效地确保内箱内的收纳容量。

具体实施方式
以下，参照附图，说明用于实施本发明的实施方式。此外，以下说明的是用于具体化本发明的技术思想的，除非有特定的记载，否则本发明不限定于以下内容。
在各附图中，有时对具有相同功能的构件，标注相同符号。为了明确说明，有时也夸张地示出各附图所示的构件的大小和位置关系等。在本说明书中，示出了将冰箱载置于水平地面上的情况，将门侧设为前侧，将其相反侧设为后侧。在附图中用箭头示出了上下前后左右的方向。
(本发明的一个实施方式的冰箱)
图1是示出本发明一个实施方式的冰箱2的外形的立体图。图2是示出图1所示的冰箱2的内部结构的侧视图。图3是示出图2所示的内部结构(特别是隔板12、12’、底板14A、14B上设置的通风口16、底板风道入口18)的立体图。
本发明的一个实施方式的冰箱2在外箱(框体)4的内部，并排地设置有第一内箱10A和第二内箱10B。在第一内箱10A及第二内箱10B的内部，收纳食品、饮料等收纳物。在外箱4的前侧开口中，设置有用于开闭第一内箱10A的门6A和用于开闭第二内箱10B的门6B。门6A、6B在并排的第一内箱10A和第二内箱10B的外侧，具有上下延伸的旋转轴，是所谓的对开门(也称为法式门)。因此，第一内箱10A和第二内箱10B之间的隔断部分通常成为死空间。
在本实施方式的冰箱2中，在第一内箱10A和第二内箱10B之间的空间形成的死空间中，设置了气体风道20。在该风道20内，设置了蒸发器22和循环风扇24。在风道20的上侧，设置了与第一内箱10A连通的第一上侧开口26A、以及与第二内箱10B连通的第二上侧开口26B。在本实施方式中，在风道20的上侧，具有左右延伸的管道部20B，在管道部20B的左右的端部，设置有第一上侧开口26A、第二上侧开口26B。
利用这种结构，第一内箱10A和第二内箱10B的深度尺寸和高度方向尺寸不会因蒸发器22和循环风扇24的设置空间而受制约。因此，假设即使在将本实施方式的冰箱2设置在深度尺寸、高度尺寸受限的场所(如整体厨房内部)的情况下，也能够高效地确保收纳空间。
在整体厨房中，由于与深度尺寸、高度尺寸相比，横向的尺寸能够相对较大， 所以能够期望通过并排设置第一内箱10A和第二内箱10B来获得足够的收纳容量。如果是宽度大并且高度尺寸、深度尺寸受限，则本实施方式的冰箱2不仅可以安装在整体厨房中，还能够安装在在缝隙家具的安装空间中。
此外，由于第一内箱10A及第二内箱10B之间的空间过去为死空间，现在被有效的利用设置风道20，在其中设置蒸发器22及循环风扇24，所以能够实现高效的配置。这样的配置能够应用于任意有隔断的并排类型的冰箱。
在本实施方式的冰箱2中，压缩机32、冷凝器和蒸发器22被流体连接，制冷剂在内部进行循环，形成冷却循环。蒸发器22通过与制冷剂的热交换，来冷却在风道20内流动的气体。压缩机32压缩由蒸发器22汽化的制冷剂，使其流到冷凝器中而液化，返回到蒸发器22。
下面描述本实施方式的冰箱2的风道20内的气体流动。循环风扇24设置在风道20内的蒸发器22的上侧，从下侧吸引气体，向上侧排出。因此，通过循环风扇24，气体在风道20内从下向上流动，在通过蒸发器22时被冷却。通过了蒸发器22的冷空气由循环风扇24排出，使冷空气撞到风道20的上表面，在上表面左右分开流动，分别流向第一上侧开口26A和第二上侧开口26B。此时，在风道20的上表面，形成有引导面20A，所述引导面20A由中央凸起的平滑的曲面构成。冷空气沿着引导面20A，流畅地向左右大致等分地分开流动。但是，不限于此，根据引导面20A的形状，也能够使左右分开流动的气体的流量成为不同的比例。
如上所述，根据本实施方式，通过循环风扇24，向上侧排出气体，排出的气体沿着风道20的上表面的引导面20A左右分开流动，经由第一上侧开口26A和和第二上侧开口26B，流入到第一内箱10A和第二内箱10B。由此，能够利用一个循环风扇22，高效地向两个内箱10A、10B内供应冷空气。
经由第一上侧开口26A流入到第一内箱10A的气体在第一内箱10A中流动，对其中的收纳物进行冷却，经由下方的第一下侧开口28A返回到风道20。经由第二上侧开口26B流入到第二内箱10B的气体在第二内箱10B中流动，对其中的收纳物进行冷却，经由下方的第二下侧开口28B返回到风道20。返回的气体再次被循环风扇24吸引，形成一系列的冷却循环。由此，能够使第一内箱10A及第二内箱10B的内部作为冷藏室、冷冻室发挥作用。将在后面详细叙述第一内箱10A和第二内箱10B中的气体流动。
在本实施方式中，设置有压缩机32的机器室30位于第一内箱10A的下侧。机器室30仅设置在第一内箱10A的下侧，所述机器室30设置有构成冷却循环的相对 较大的构件。因此，第一内箱10A的下表面的高度高于第二内箱10B的下表面的高度。由此，能够使第二内箱10B的收纳区域的高度尺寸较大，从而能够得到充分的收纳容量。但是，不限于该设置，也可能存在如下的情况：相反，机器室30只设置在第二内箱10B的下侧，第二内箱10B的下表面的高度高于第一内箱10A的下表面的高度。
如上所述，根据本实施方式的冰箱2，由于蒸发器22被设置在左右并排的第一内箱10A和第二内箱10B之间，所以不会受到内箱10A、10B的前后方向和上下方向的尺寸的制约。因为蒸发器22纵向配置，所以能够缩小接收皿，所述接收皿接收除霜时产生的液滴。因此，能够高效地设置蒸发器22，以高效地确保内箱10A、10B内的储存容量。
此外，由于设置有蒸发器22的风道20被内箱10A、10B包围，所以能减少热泄露，从而获得高的热效率。此外，通过使内箱10A、10B之间的空间成为风道20，能够以非常简单的结构来形成风道。
(内箱中的气体流动)
接着，参照图2和图3，说明第一内箱10A和第二内箱10B中的气体流动。在图2中，在图3中，气体的流动用虚线的箭头示意性地表示。
＜第一内箱＞
在第一内箱10A中，没有设置上下划分内部空间的隔板，在底部设置有平板形状的底板14A。由此，第一内箱10A内部的全部高度可以用来存储收纳物，因此，适合收纳例如酒、饮用水的瓶子等。
底板14A的内部是中空的，在左端设置有底板风道入口18，该底板风道入口18使得在第一内箱10A中流动的气体流入到底板14A的内部。在底板14A的右端，设置有第一下侧开口28A，其使得在底板14A内部流动的气体流出到风道20内。
由此，从第一上侧开口26A流入到第一内箱10A的气体被引导到第一内箱10A的内壁，从上侧流向下侧，在该期间内，对其中的收纳物进行冷却。然后，从底板风道入口18流入到底板14A，在底板14A内从左向右流动，从第一下侧开口28A流到风道20内。在风道20内流动的气体通过循环风扇22的吸引力，从下向上流动，再次通过蒸发器22。
使底板14A内部变为中空，成为气体的风道，由此，仅通过在第一内箱10A底部设置底板14A，就能够以简单的结构，容易地将第一内箱10A内的气体引导到风道20内。
<第二内箱>
另一方面，在第二内箱10B中，设置有2个隔板12、12’上下划分内部空间。隔板12、12’在前后方向上延伸到第二内箱10B的内部形状极限，从而获得更大的收纳空间。这些隔板12、12’的内部也是中空的。在底部设置有底板14B。底板14B具有L形的侧面形状，内部是中空的。底板14B具有L形的侧面形状而不是平板状是因为，设置有底板14B的第二内箱10B的底部的位置低于位于机器室30上侧的风道20的底部，因此设置了将该高度之差上下连接的风道。
在上侧的隔板12中，在右侧的端部，设置有连通上下的通风口16，在下侧的隔板12’中，在与之相反的左侧的端部，设置有连通上下的通风口16。在底板14B的右端，设置有底板风道入口18，该底板风道入口18使得在第二内箱10B中流动的气体流入到底板14B内部。在底板14B的左端，设置有第二下侧开口28B，该第二下侧开口28B使得在底板14B内部流动的气体流出到风道20内。
由此，从第二上侧开口26B流入到第二内箱10B的气体沿着上侧的隔板12的上表面，从左向右流动。然后，通过通风口16，流入到被隔板12分隔的下侧的空间。流入的气体沿着上侧的隔板12的下表面，从右向左流动，并且向下侧流动。然后，通过设置在下侧的隔板12’中的通风口16，流入到被下侧的隔板12’分隔的下侧的空间。流入的气体沿着下侧的隔板12’的下表面，从左向右流动，并且向下侧流动。然后，从底板风道入口18流入到底板14A，在底板14A内，从右向左，进一步地，从下向上流动，从第二下侧开口28B流到风道20内。在风道20内流动的气体通过循环风扇22的吸引力，从下向上流动，再次通过蒸发器22。
通过这样的气体流动，能够高效地冷却收纳物，所述收纳物载置于隔板12、12’以及底板14B上。
在此，隔板12、12’的数量不限于两个，能够设置两个以上的任意数量的隔板。关于设置通风口16的左右的位置，也能够根据第二内箱10B内的配置来任意地设定。在上侧的隔板12中，优选地，在与第二上侧开口26B的位置相反侧的端部设置通风口16，所述上侧的隔板12对从第二上侧开口26B流入的气体进行引导。在配置于其下方的下侧的隔板12’中，优选地，在与设置有上侧的隔板12的通风口16的端部相反侧的端部设置通风口16。也就是说，优选地，在上侧的隔板12中，在左右方向中的一个的端部，设置连通上下的通风口16，在下侧的隔板12’中，在左右方向中的另一个的端部，设置通风口16。
如上所述，根据本实施方式，在利用多个隔板12、12’来划分内部空间的情况 下，隔板12、12’的内部是中空的，在上下的隔板12、12’中，连通上下的通风口16彼此设置在左右相反侧的端部。由此，从第二上侧开口26B流入的气体在第二内箱10B内，沿着隔板12、12’，左右Z字形地流动，同时向下侧流动，因此，能够充分地冷却载置于隔板12、12’上的收纳物。
关于底板14B，也在与通风口16左右相反侧的端部，设置有底板风道入口18，所述通风口16设置在位于上方的隔板12’中。由此，气体在第二内箱10B内，左右Z字形地流动，能够充分地冷却载置于底板14B上的收纳物。
与底板14A相同，使底板14B内部变为中空，成为气体的风道，由此，仅通过在第二内箱10B底部设置底板14B，就能够以简单的结构，容易地将第二内箱10B内的气体引导到风道20内。
(内箱的下侧的气体流动)
图4是示出第一及第二内箱10A、10B的下侧的结构的立体图。在图4中，第一内箱10A和第二内箱10B下侧的气体流动也用虚线示出。如上所述，在第一内箱10A的下侧，存在设置有压缩机32的机器室30，第一内箱10A的下表面的高度高于第二内箱10B的下表面的高度。
由此，能够在第二内箱10B中确保充分的收纳容量，并且，能够有效利用通常成为死空间的第二内箱10B下侧的空间。在第二内箱10B中，下侧的空间的高度是有限的，但是，如图4所示，设置了不需要高度的蒸发皿36和蒸发冷凝器34。在此，为了示出蒸发冷凝器34，用虚拟线示出了蒸发皿36。
蒸发皿36与接收皿通过排水管连接，所述接收皿设置在蒸发器22下侧，蒸发器22除霜过程中产生的水流入接收皿中。在蒸发器22的下侧，设置有蒸发冷凝器34，从压缩机32排出的高温的制冷剂流经蒸发冷凝器34。蒸发器22中积存的水被蒸发冷凝器34加热，促进蒸发。
如上所述，根据本实施方式，机器室30只配置在第一内箱10A下，所述机器室30设置有有包括压缩机32和其他需要高度的构件，因此，能够在第二内箱10B中，确保充分的收纳容量。同时，通过在第二内箱10B下侧的空间中，设置不需要高度的蒸发皿36和蒸发冷凝器34，能够利用死空间实现高效配置。
(内箱下侧的结构)
如图4所示，在机器室30中，设置了冷却风扇40。通过冷却风扇40，外部空气从前侧流入到第二内箱10B的下侧，从第二内箱10B的下侧流向第一内箱10A的下侧的机器室30，从机器室30向前侧排出。通过该气体流动，能够有效地冷却高温 的构件，包括压缩机32、冷凝器。此时，能够从冰箱2下部的前侧吸入外部空气，将温度上升后的气体向冰箱2下部的前侧排出。
通过该气体流动，假设即使在冰箱2设置在整体厨房中的情况下，也能够在不会对周围的构件产生热影响的情况下，实现高效的冷却。
虽然说明了本发明的实施方式、实施形态，但是公开内容可以在结构的细节方面变化，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，实现实施方式、实施形态中的要素的组合和顺序的变化等。
