本发明涉及一种具有自动制冰单元的冰箱及其控制方法。
背景技术
传统具有自动制冰单元的冰箱中，该自动制冰单元具有制冰皿和使制冰皿旋转的驱动马达。在这样的自动制冰单元中，在制冰后用驱动马达旋转制冰皿使其上表面向下，从而使所生成的冰落入设置在下方的收纳容器中以收纳这些冰。
在具有所述自动制冰单元的冰箱中，提出了能从冰箱卸下自动制冰单元的方案(例如，参考专利文献1：日本特开2006-105419号专利)。在专利文献1所记载的冰箱中，例如在不那么需要冰的冬季卸下自动制冰单元，从而能将卸下了自动制冰单元的区域有效活用为冷冻收纳区域。
然而，由于吹出口被设置成使得通过了蒸发器的冷气在制冰皿周围流动，因此可能会有制冰皿下侧的收纳容器设置于其中的更大收纳区域中的冷气供给并不充足的问题。于是，存在无法高效地冷却卸下了自动制冰单元的区域、无法将其充分利用为冷冻收纳区域的问题，于是，存在无法充分地实现急速冷冻的问题。
因此，需要一种改进的冰箱及其控制方法是亟待解决的技术难题。
发明内容
本发明的目的在于提供一种冰箱及其控制方法，其能够高效地冷却冷冻室内的卸下了自动制冰单元的区域、能够可靠地增加有效使用的冷冻收纳区域，并且能可靠地实现急速冷冻。
为实现上述目的，本发明提供了一种冰箱，其具有冷冻室，所述冷冻室内设有：可拆卸的自动制冰单元，其具有制冰皿和使所述制冰皿旋转的驱动马达；吹出口，其使得通过了蒸发器的气体向所述制冰皿流出；以及急速冷冻管路，其在卸下了所述自动制冰单元时以可拆卸地状态安装到卸下的区域；所述急速冷冻管路包括：壳体，插入口，其设在所述壳体上且与所述吹出口相对，或者具有所述吹出口的制冰用管路插入所述插入口使得所述吹出口位于所述壳体内，冷却风扇，其设置在所述壳体内，提高从所述吹出口流入所述壳体内的气体的流速并排出这些气体，以及出风口，其设在所述壳体上，以供从所述冷却风扇排出的气体向所述壳体的外部流出。
如此，通过包括在急速冷冻管路的壳体内的冷却风扇来提高通过了蒸发器从吹出口流出的气体的流速，从而能够将这些气体从壳体的出风口供给至冷冻室内。如此，高效地冷却了冷冻室内的卸下了自动制冰单元的区域，能够可靠地增加有效使用的冷冻收纳区域，并且能够可靠地实施急速冷冻。
进一步地，所述冷却风扇的排出方向朝向下侧，并且相对于气体从所述吹出口流出的方向成15度以上45度以下的角度。
如此，由于冷却风扇的排出方向相对于吹出口的吹出方向成15度以上45度以下的范围的角度并且朝向下侧，因此能够向包括设置在吹出口下侧的收纳容器的内部在内的更大的收纳区域供给冷气，因此能够可靠且高效地冷却冷冻室内的卸下了自动制冰单元的区域。
进一步地，所述冰箱还包括：用于控制所述自动制冰单元和所述急速冷冻管路的控制器，以及用于以可拆卸的状态与所述自动制冰单元的单元侧连接器连接的制冰用连接器，所述急速冷冻管路包括用于以可拆卸的状态与所述制冰用连接器连接的管路侧连接器，所述控制器进行控制，使得在所述急速冷冻管路安装到卸下了所述自动制冰单元的区域且所述管路侧连接器连接到所述制冰用连接器的状态下经由彼此连接的所述制冰用连接器和所述管路侧连接器来向所述冷却风扇的风扇马达供电。
如此，通过使用可拆卸到用于向自动制冰单元供电的制冰用连接器的管路侧连接器，能够可靠地向冷却风扇的风扇马达供电。
进一步地，连接到所述管路侧连接器的配线装有用于防止反极性的二极管。
当管路侧连接器连接到制冰用连接器时，可能会发生连接器的极性被反向连接的问题。在连接器的极性被反向连接就通电的情况下，会发生冷却风扇的风扇马达逆转的不好现象。在本发明中，通过用于防止反极性的二极管，使得电流在连接器正确连接的情况下流动，而不会发生电流在连接器的极性反向连接的情况下流动。通过该用于防止反极性的二极管，能够始终恰当地运转冷却风扇。
进一步地，所述冰箱设置有位于自动制冰单元上侧的间隔板，所述间隔板上形成有滑动支承部，所述自动制冰单元的基部的两端以可滑动的方式插入到滑动支承部和间隔板围成的空间中。
进一步地，所述自动制冰单元在滑动支承部的引导下向后滑动移动，直至在设定位置处与冰箱相卡扣，此时所述自动制冰单元上的单元侧连接器连接到固定在冰箱上的制冰用连接器。
进一步地，所述壳体的后侧设置所述插入口、前侧设置所述出风口，所述出风口呈网眼状。
为实现上述发明目的，本发明还提供了一种冰箱的控制方法，包括：
步骤S2：判断冷冻室的前门是否打开；
步骤S4：若前门打开，则判断单元侧连接器是否连接到制冰用连接器；
步骤S6：当辨别出单元侧连接器连接到制冰用连接器时，进行用于使用自动制冰单元来制冰的控制处理；
步骤S8：判断是否接收到根据使用者的开关操作的开启急速冷冻的信号；
步骤S10：若辨别出接收到了开启急速冷冻的信号，则开始对风扇马达送电，风扇马达正向旋转以运转冷却风扇。
进一步地，所述控制方法还包括：
步骤S12：判断是否接收到根据使用者的开关操作的关闭急速冷冻的信号；
步骤S14：若辨别出接收到了关闭急速冷冻的信号，则停止对风扇马达的送电，使风扇马达的旋转停止从而停止冷却风扇的运转；
步骤S16：判断前门是否打开，若否，则重复步骤S8至S14；若是，则返回步骤S4并重复其后步骤。
进一步地，所述步骤S10还包括若辨别出没有接收到开启急速冷冻的信号，则变为待机状态。
本发明的有益效果是：本发明的冰箱及其控制方法能够高效地冷却冷冻室内的卸下了自动制冰单元的区域，能够可靠地增加有效使用的冷冻收纳区域，并且能可靠地实施急速冷冻。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本发明进行详细描述。
(冰箱)
图1是本发明的冰箱2中的急速冷却管路20的安装结构的侧视截面图。图2是沿图1中的箭头A-A看急速冷却管路20的前侧视图。图3是本发明的冰箱2中的自动制冰单元50的安装结构的侧视截面图。
首先参考图1至图3来说明本发明的冰箱2的概况。在图1和图3中，示出了冰箱2的冷冻室4和设置在其后侧的冷却流路10。未图示的冷藏室设置在冷冻室4的上侧。
蒸发器12和冰箱侧风扇14设置在冷却流路10中。蒸发器12构成了冷媒在其中流动的冷却循环机构的一部分。在冷却循环机构中，被压缩机6排出的冷媒流经冷凝器、毛细管等而流入蒸发器12，流过了蒸发器12的热交换管的冷媒再次返回压缩机6的吸入侧。
通过运转冰箱侧风扇14，冷却流路10内的气体按由下向上的方向流动并通过蒸发器12。 气体当在蒸发器12的热交换管之间通过时被冷却。冷却后的气体经由制冰用管路16的吹出口16A流入冷冻室4内。尽管还存在供通过了蒸发器12的气体流入冷冻室4内的其他开口，但是这里仅示出了制冰用管路16的吹出口16A。
在本实施方式所涉及的冰箱2中，如图3所示，自动制冰单元50设置在冷冻室4内。进一步地，如图1、图2所示，卸下自动制冰单元50后，可以代之以将急速冷却管路20设置在冷冻室4内。例如，由于夏季耗冰较多，因此在冰箱2中设置自动制冰单元50来制冰。另一方面，由于冬季耗冰减少，因此可以卸下自动制冰单元50，将空下来的空间转用作冷冻室4内的冷冻收纳区域。
(自动制冰单元)
首先，参考图3来说明冷冻室4内的自动制冰单元50的安装结构。自动制冰单元50包括树脂制的制冰皿52和具有使制冰皿52旋转的驱动马达54A的驱动部54。从冰箱2的冷却流路10延伸至前侧的制冰用管路16设置在制冰皿52的后侧，并且制冰用管路16的吹出口16A的开口朝向制冰皿52。
通过了蒸发器12的气体在冰箱侧风扇14的风力作用下流入制冰用管路16，在制冰用管路16内流动，并从吹出口16A流出到冷冻室4。气体以大致水平方向为中心稍微扩散地从吹出口16A流出。如此，从吹出口16A流出的气体沿着制冰皿52的上表面、两个侧面和底面从后向前流动。通过如此的冷气流动来冷却储存在制冰皿52的各个格子中的水并使之冻结。
在冻结各个格子中的水而制冰时，构成冰箱2的控制装置的一部分的控制器60向驱动部54的驱动马达54A供电，使制冰皿52旋转，使得上表面本来朝向上侧的制冰皿52变为其上表面朝向下侧。在旋转时，制冰皿52的一部分变为与冰箱2相抵接，在进一步旋转制冰皿52时，制冰皿52被扭转使得冰从格子脱离。然后，冰落下并收纳到设置在制冰皿52下方的收纳容器44中。
冰箱2设置有位于自动制冰单元50上侧的间隔板40，间隔板40上形成有滑动支承部42，在宽度方向上在自动制冰单元50的左右端部的位置，滑动支承部42沿前后方向延伸。滑动支承部42从其长度方向呈L形(参考图2)。自动制冰单元50的基部的两端以可滑动的方式插入到L形的滑动支承部42和上侧的间隔板40围成的空间中。
打开覆盖冰箱2的冷冻室4的前门，将自动制冰单元50的基部的两端放入L形的滑动支承部42和间隔板40围成的空间中，并将自动制冰单元50塞到后方，即可将自动制冰单元50安装到冷冻室4内。如此，自动制冰单元50在滑动支承部42的引导下向后滑动移动，直至最终在设定位置处与冰箱2相卡扣。
当自动制冰单元50向后滑动移动至到达设定位置时，固定在自动制冰单元50上的单元侧连接器56连接到固定在冰箱2上的制冰用连接器18。例如，可以以单元侧连接器56具有凸形销而制冰用连接器18具有凹形销的情况为例。此外，相反地单元侧连接器56具有凹 形销而制冰用连接器18具有凸形销的情况也是可以的。
单元侧连接器56与驱动部54的驱动马达54A电气连接，制冰用连接器18与被控制器60控制的电源部电气连接。如此，来自电源部的电力基于控制器60的控制信号经由彼此连接的制冰用连接器18和单元侧连接器56而供给至驱动马达54A。如此，可以通过运转驱动马达54A来使制冰皿52旋转。
在将自动制冰单元50从冷冻室4拆卸到外部时，打开覆盖冰箱2的冷冻室4的前门，松开固定自动制冰单元50的卡扣，将自动制冰单元50向面前拉。此时，单元侧连接器56从制冰用连接器18断开。如此，自动制冰单元50在滑动支承部42的引导下向前滑动移动，从而可以容易地将自动制冰单元50取出到冷冻室4外面。
如上所述，自动制冰单元50以可拆卸的方式安装到冰箱2的冷冻室4，并且自动制冰单元50的单元侧连接器56以可拆卸的方式连接到制冰用连接器18。
(急速冷冻管路)
接下来，参考图1和图2来说明冷冻室4内的急速冷却管路20的安装结构。急速冷却管路20包括内部具有供气体流动的空间的壳体22。板状的滑动座22A延伸到壳体22的左右两侧。如图2所示，滑动座22A的左右两侧的端部以能滑动的状态插入到L形的滑动支承部42和上侧的间隔板40围住的空间中。如此，急速冷却管路20能在滑动支承部42的引导下前后滑动移动。由此，可以用与自动制冰单元50同样的方法来进行急速冷却管路20到冷冻室4的安装和从冷冻室4的拆卸。
壳体22的后表面侧设有插入口24。冰箱2的制冰用管路16经由该插入口24而插入壳体22内，如此，制冰用管路16的吹出口16A位于壳体22内。如此，通过了蒸发器12的气体经由制冰用管路16而流入壳体22内。
然而，不限于这样的结构，例如，制冰用管路16自冷却通路10向前的突出量比所图示的情况少的情况也是可以的。在这种情况下，制冰用管路16也可以不插入到壳体22内，而是制冰用管路16的吹出口16A位于壳体22的后表面的后侧。如此，通过设置成使得插入口24与吹出口16A相对，通过了蒸发器12的气体可以流入壳体22内。
壳体22内设置有冷却风扇28，从制冰用管路16的吹出口16A流入壳体22内的气体被该风扇吸引并从其排出口排出。通过冷却风扇28，可以提高流入的气体的流速再排出。冷却风扇28包括使叶轮旋转的风扇马达28A。冷却风扇28与固定到壳体22的管路侧连接器30电气连接，管路侧连接器30可与制冰用连接器18连接，如此，与自动制冰单元50同样，风扇马达28A可以从冰箱2的电源部接收电力。
壳体22的前侧设有出风口26，供从冷却风扇28排出的气体向壳体22的外部流出。在本实施方式中，具有用细窄部件间隔成网眼状的出风口26。如此，通过了蒸发器12的气体可以从吹出口16A流入壳体22内，流入的气体被冷却风扇28提高风速，从出风口26吹出到壳体22的外部。如此，可以更高效地冷却冷冻室4，并且可以实施急速冷冻。
此外，可以以上述的同样的顺序将急速冷却管路20安装到冷冻室4内的卸下了自动制冰单元50的区域。具体地，打开覆盖冰箱2的冷冻室4的前门，将急速冷却管路20的滑动座22A的两端放入L形的滑动支承部42和间隔板40围成的空间中，将急速冷却管路20塞到后方。如此，急速冷却管路20在滑动支承部42的引导下向后滑动移动，最终在设定位置上与冰箱2相卡扣。此时，制冰用管路16经由插入口24插入到壳体22的内部。
当急速冷却管路20向后滑动移动至到达设定位置时，固定在急速冷却管路20上的管路侧连接器30连接到固定在冰箱2侧的制冰用连接器18。管路侧连接器30具有与自动制冰单元50的单元侧连接器56同样的销形状。
如此，来自电源部的电力基于控制器60的控制信号经由彼此连接的制冰用连接器18和管路侧连接器30而供给至冷却风扇28的风扇马达28A，如此以使冷却风扇28运转。
在将安装到冷冻室4的急速冷却管路20拆卸到外部的情况下，打开覆盖冰箱2的冷冻室4的前门，松开固定急速冷却管路20的卡扣，将急速冷却管路20向面前拉。此时，管路侧连接器30从制冰用连接器18断开如此，急速冷却管路20在滑动支承部42的引导下向前滑动移动，可以容易地将急速冷却管路20取出到冷冻室4外面。
如上所述，本发明的冰箱2在冷冻室4内设有：具有制冰皿52和使制冰皿52旋转的驱动马达54A的可拆卸的自动制冰单元50，使通过了蒸发器12的气体向制冰皿52流出的吹出口16A，以及在卸下了自动制冰单元50时以可拆卸状态安装到卸下的区域的急速冷冻管路20；急速冷冻管路20包括：壳体22，插入口24，其设在壳体22上，与吹出口16A相对，或者具有吹出口16A的制冰用管路16插入插入口24使得吹出口16A位于壳体22内，冷却风扇28，其设置在壳体22内，提高从吹出口16A流入壳体22内的气体的流速并排出这些气体，以及出风口26，其设在壳体22上，供从冷却风扇28排出的气体向壳体22的外部流出。
在本实施方式所涉及的冰箱2中，通过设置在急速冷冻管路20的壳体22内的冷却风扇28来提高通过了蒸发器12从吹出口16A流出的气体的流速，从而能够将这些气体从壳体22的出风口26供给至冷冻室4内。如此，高效地冷却了冷冻室4内的卸下了自动制冰单元50的区域，能够可靠地增加有效使用的冷冻收纳区域，并且使得能够可靠地实施急速冷冻。
特别地，本实施方式所涉及的冰箱2包括：用于控制自动制冰单元50和急速冷冻管路20的控制器60，以及用于以可拆卸的状态与自动制冰单元50的单元侧连接器56连接的制冰用连接器18；急速冷冻管路20包括用于以可拆卸的状态与制冰用连接器18连接的管路侧连接器30；控制器60进行控制，使得在急速冷冻管路20安装到卸下了自动制冰单元50的区域且管路侧连接器30连接到制冰用连接器18的状态下经由彼此连接的制冰用连接器18和管路侧连接器30来向冷却风扇28的风扇马达28A供电。
如此，在本实施方式中，通过使用可拆卸到用于向自动制冰单元50供电的制冰用连接器18的管路侧连接器30，能够可靠地向冷却风扇28的风扇马达28A供电。
(来自急速冷冻管路的气体的流动)
在急速冷却管路20中，冷却风扇28的排出方向与气体从大致水平的制冰用管路16的吹出口16A流出的方向不同。具体地，如图1所示，该方向朝向下侧，并且相对于气体从吹出口16A的流出方向成15度以上45度以下的范围的角度(图1的θ＝15度至45度)。如此，能够将冷气供给至包括设置在吹出口16A下侧的收纳容器44的内部在内的更大的收纳区域。如此，能够可靠且高效地冷却冷冻室4内的卸下了自动制冰单元50的区域。
(连接到管路侧连接器的配线)
图4是连接到管路侧连接器30的装有用于防止反极性的二极管34的配线32的电路图。当固定在急速冷却管路20上的管路侧连接器30连接到固定在冰箱2侧的制冰用连接器18时，可能会发生连接器的极性被反向连接的问题。在连接器的极性被反向连接就通电的情况下，会发生冷却风扇28的风扇马达28A逆转的不好现象。为了应对这种情况，在本实施方式中，配线32装有用于防止反极性的二极管34，安装用于防止反极性的二极管34使得其与风扇马达28A串联连接。
通过该用于防止反极性的二极管34，使得电流在连接器正确连接的情况下流动，而不会发生电流在连接器的极性反向连接的情况下流动。
(急速冷冻管路的控制)
图5是是本发明的急速冷冻管路20的控制系统的一个示例的框图。图6是管路侧连接器30连接到制冰用连接器18而实施的急速冷冻过程的控制处理的流程图。接下来，参考图5和图6来说明用于控制急速冷却管路20的控制系统和控制方法。
<用于控制冷却机构的控制系统>
控制器60构成了冰箱2的控制装置的一部分，并且控制进行冷冻室4和冷藏室的冷却的压缩机6和冰箱侧风扇14。进一步地，在单元侧连接器56连接到制冰用连接器18的情况下，控制器60控制自动制冰单元50的驱动马达54A。另一方面，在管路侧连接器30连接到制冰用连接器18的情况下，控制器60控制急速冷却管路20的风扇马达28A。
控制器60可以辨别连接到制冰用连接器18的是否是单元侧连接器56。连接到制冰用连接器18的是否是单元侧连接器56的辨别可以采用从检测端子发出检测信号的方法、检测端子间电阻的变化的方法等的任意方法。
<急速冷冻过程的控制处理>
在图6所示的控制流程中，在覆盖冰箱2的冷冻室4的前门打开时，进行确认单元侧连接器56是否安装到制冰用连接器18的控制处理。在图6中，首先判断前门是否打开(步骤S2)，在该判断中，在辨别出前门没有打开(否)时，重复该判断处理。在步骤S2的判断中，如果辨别出前门打开(是)，则接下来，判断单元侧连接器56是否连接到制冰用连接器18(步骤S4)。
在该判断中，如果辨别出单元侧连接器56连接到制冰用连接器18(是)，则进行用于 使用自动制冰单元50来制冰的控制处理(步骤S6)。然后，在前门打开时(步骤S2)，进行单元侧连接器56是否连接到制冰用连接器18的判断(步骤S4)。
在步骤S4的判断中，如果辨别出单元侧连接器56没有连接到制冰用连接器18(否)，则假定是管路侧连接器30连接到制冰用连接器18，进行用于运转/停止冷却风扇28的控制处理。
首先，判断是否接收到根据使用者的开关操作的开启急速冷冻的信号(步骤S8)。在该判断中，如果辨别出没有接收到开启急速冷冻的信号(否)，则变为待机状态。也就是说，风扇马达28A继续处于停止状态。在步骤S8的判断中，如果辨别出接收到了开启急速冷冻的信号(是)，则接下来开始对风扇马达28A送电，风扇马达28A正向旋转以运转冷却风扇28(步骤S10)。假设是单元侧连接器56没有连接到制冰用连接器18的情况，即使实施进行送电的控制处理，实际上也不会有电气流向风扇马达28A，并且冷却风扇28不会运转。
接下来，判断是否接收到根据使用者的开关操作的关闭急速冷冻的信号(步骤S12)。在该判断中，如果辨别出没有接收到关闭急速冷冻的信号(否)，则变为待机状态。也就是说，风扇马达28A继续旋转状态，并且继续急速冷冻。在步骤S12的判断中，如果辨别出接收到了关闭急速冷冻的信号(是)，则停止对风扇马达28A的送电，使风扇马达28A的旋转停止从而停止冷却风扇28的运转(步骤S14)。
然后，进行前门是否打开的判断(步骤S16)。在该判断中，如果辨别出前门没有打开(否)，则重复步骤S8至S14所示的用于使冷却风扇28运转/停止的控制处理。在步骤S16的判断中，如果辨别出前门打开(是)，则返回步骤S4，再次进行单元侧连接器56是否连接到制冰用连接器18的判断，并重复上述控制处理。
在上述控制处理中，基于根据使用者的开关操作的开启/关闭急速冷冻的信号来进行使冷却风扇28运转/停止的控制，然而不限于此。例如，也可以考虑如下方案：控制器60基于设置在冷冻室4内的温度传感器、优选地设置在收纳容器44所设置于的区域中的温度传感器的测定数据来发送开启/关闭急速冷冻的信号，并且基于该开启/关闭急速冷冻的信号来控制冷却风扇28的运转/停止。此时，优选地与压缩机6、冰箱侧风扇14的控制关联地进行冷却风扇28的控制。
以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围。
