根据本发明，在判断为包含装水制冰盘的组件不存在于冰箱内时，将下限值的值变更为比通常设定值更低的特别设定值，从而即使在卸下了自动制冰装置的包含装水制冰盘的组件的情况下，也与包含装水制冰盘的组件存在于冰箱内情况同样地，能实现冷冻室内的适当的温度控制。
另外，本发明中，所述冰箱具备传感器，所述传感器检测所述包含装水制冰盘的组件是否存在于冰箱内，所述控制部基于所述传感器的检测信号，来决定是将所述下限值的值设为所述通常设定值还是设为所述特别设定值。

具体实施方式
接下来，参照附图来详细说明本发明的具体实施方式。对具有同样功能的对应的元件，在全部图中赋予相同的附图标记。
(本发明的1个实施方式所涉及的冰箱)
图1是示意性地表示具有本发明1个实施方式所涉及的具有自动制冰装置40的冰箱的内部构造的侧面剖视图，是表示包含装水制冰盘的组件存在于冰箱内的情况的图。图2是表示包含装水制冰盘的组件不存在于冰箱内的情况的图。图3是表示本发明的1个实施方式所涉及的冰箱的控制装置的概要的框图。图4是表示本发明的1个实施方式所涉及的冰箱表示下限值为通常的设定值(以下称为“通常设定值”)的情况下的温度传感器的检测值以及冷冻室温度的曲线图。
本发明的1个实施方式所涉及的冰箱2具备以冷冻室4为主的对冰箱内进行冷却的冷却部50。冷却部50如图1、2所示，具有通过配管进行连接的压缩机52、冷凝器54以及蒸发器56。经压缩器52压缩后的冷媒(气体)由冷凝器54液化，液化后的冷媒由于蒸发器56带走冰箱2内的气体的热量而气化，气化后的冷媒由压缩器52再次压缩，即，重复这样的循环。在冰箱2的箱内，通过风扇58来使气体循环，经过蒸发器56后的冷气被供应至冷藏室或冷冻室4。冷气经由出风口8而被供应至冷冻室4。供应后的冷气在冷冻室4内循环后，从回风口9排出，再次到达蒸发器56的下侧，重复同样的流动。冰箱2包括进行制冷控制的控制部100。
本实施方式所涉及的冰箱2具有自动地将立方体状的冰向储冰盒30供应的自动制冰装置40。在该自动制冰装置40，在冷冻室4内设置有包含装水制冰盘12 的组件10，并在组件10的下侧配置有储冰盒30。组件10除了装水制冰盘12以外，还包括使装水制冰盘12旋转的旋转机构14以及检冰杆16，检冰杆16检测在储冰盒30内是否有规定量以上的冰。
自动制冰装置40还在配置有组件10的冷冻室4的上方具备供应机构20，供应机构20将贮水罐22内的水向装水制冰盘12供应。供应机构20具备贮水罐22、泵24以及配管26。通过泵24的驱动，蓄存在贮水罐22内的水经过配管26而被供应至装水制冰盘12。
供应机构20还具备卷绕于配管26的外周的防冻加热器28。通过防冻加热器28来防止配管26的冻结，能始终将贮水罐22内的水供应给装水制冰盘12。
在包含装水制冰盘12的组件10的下方，并且在冷冻室4的后表面4A，设置有用于冰箱内的冷却控制的温度传感器60。
在本实施方式所涉及的冰箱2中，在无需较多冰的冬天时期等，能将包含装水制冰盘12的组件10卸下到外部。由此，能将原本配置了冷冻室4的组件10的区域用作收纳冷冻食品的空间。
(控制部)
如图3所示，冰箱2的控制部100进行自动制冰装置40以及冰箱内的冷却控制。作为自动制冰装置40的控制，进行如下控制：基于来自检冰杆16的信号来驱动旋转机构14，使装水制冰盘12旋转180度，并使冰落下至储冰盒30。另外，使装水制冰盘12旋转180度复原后，驱动泵24来进行向装水制冰盘12供应水的控制。进而，为了防止从贮水罐22向装水制冰盘12供应水的配管26冻结，进行对防冻加热器28通电的控制。
作为冰箱内的冷却控制，基于来自温度传感器60的信号，控制压缩机52的运行、停止。另外，基于来自温度传感器60的信号，控制风扇58的起动、停止。
＜自动制冰装置的控制＞
在本实施方式所涉及的冰箱2中，向冷冻室4吹入冷气的出风口8被配置为向包含装水制冰盘12的组件10的上方、尤其是装水制冰盘12的上面供应冷气。由此，能将装水制冰盘12内的水进行冷却并制冰。
在这样的构成的自动制冰装置40中，基于来自检冰杆16的信号，在判断为储冰盒30内的冰并非规定量以上时，控制部100驱动旋转机构14的电动机，使装水制冰盘12扭转的同时旋转180度。由此，能使装水制冰盘12内的冰落入储冰盒30内进行供应。在使旋转后的装水制冰盘12返回至原来的位置后，控制部100驱动泵24，从贮水罐22向装水制冰盘12进行供水。供应至装水制冰盘12的水通过从出 风口8供应来的冷气进行制冰。
控制部100进而为了防止从贮水罐22向装水制冰盘12供应水的配管26冻结，进行对防冻加热器28供应电力的控制。
＜冰箱内的冷却控制＞
控制部100基于温度传感器60的检测值来进行冰箱内的冷却的控制。在温度传感器60的检测值达到上限值时，开始压缩机52的运行。由此，向冷冻室4内供应冷气，冷冻室4内的温度下降。然后，在温度传感器60的检测值达到下限值时，进行使运行中的压缩机52停止的控制。在压缩机52的停止后，冷冻室4内的温度上升，在温度传感器60的检测值达到上限值时，再次运行压缩机52。将这样的压缩机52的运行开始、停止、至下次开始运行为止的工序称为1个冷却循环。控制部100至少在压缩机52驱动的期间进行控制以驱动风扇58。
在包含装水制冰盘12的组件10存在于冰箱内(冷冻室4之中)的情况下，如图1的粗箭头所示，从出风口8吹出的冷气沿装水制冰盘12的上面流动。然后，经由装水制冰盘12的左右两端与冷冻室4的两侧面之间的空间而向下方流动。流至下方的气体经由回风口9而向冷冻室4的外部排出。故而，不会发生从出风口8吹出的冷气直接向温度传感器60流动的情况。
另一方面，在包含装水制冰盘12的组件10不存在于冰箱内的情况下，如图2的粗箭头所示，由于没有遮蔽物，因此从出风口8吹出的冷气直接向温度传感器60流动。然后，气体流向下方，经由回风口9而向冷冻室4的外部排出。由此，与包含装水制冰盘12的组件10存在于冰箱内的情况相比，温度传感器60的周围的气体的温度更快地下降。由此，存在如下可能：若控制部100进行相同的冷却控制，则无法适当控制冷冻室4内的温度。关于该情况，在下面详细描述。
(下限值为通常设定值的情况下的冷却循环)
图4是表示下限值为通常的设定值(以下称为“通常设定值”)的情况下的温度传感器的检测值以及冷冻室温度的曲线图，是将包含装水制冰盘12的组件10存在于冰箱内的情况与不存在的情况进行比较而示出的曲线图。上侧的曲线图表示在冷冻室4之中的包含装水制冰盘12的组件10的下方配置的温度传感器60的检测值随时间的位移。下侧的曲线图表示在冷冻室4之中的实际的温度(例如，全体的平均温度)随时间的位移。每一张曲线图均是横轴表示时间，纵轴表示温度。将包含装水制冰盘12的组件10存在于冰箱内的情况下的温度用实线表示，将该组件10不存在的情况下的温度用虚线表示。
首先，说明以实线表示的包含装水制冰盘12的组件10存在于冰箱内的情况 下的温度变化。曲线图的左端示出控制部100刚开始压缩机52的运行。通过压缩机52的运行，冷冻室4内的温度下降，温度传感器60的检测值下降。然后，在温度传感器60的检测值达到下限值TL时，控制部100进行使运行中的压缩机52停止的控制。由此，冷冻室4内的温度上升，温度传感器60的检测值上升。然后，在温度传感器60的检测值达到上限值TH时，控制部100再次开始压缩机52的运行。由此，压缩机52的运行开始、停止且至下次运行开始为止的1个冷却循环结束。
通过这样的温度控制，如图4的下侧的曲线图所示，冷冻室4内的温度从temp1下降至temp3，在压缩机52停止后，从temp3上升至temp1。在图3中，示出了2次冷却循环。
接下来，说明以虚线表示的包含装水制冰盘12的组件10不存在于冰箱内的情况下的温度变化。通过压缩机52的运行，冷冻室4内的温度下降，温度传感器60的检测值下降。此时，从出风口8吹出的冷气直接向温度传感器60流动，因此与以实线表示的包含装水制冰盘12的组件10存在于冰箱内的情况相比，温度传感器60的检测值更快地下降。由此，与组件10存在于冰箱内的情况相比，以更短的时间达到下限值TL。在温度传感器60的检测值达到下限值时，控制部100进行使运行中的压缩机52停止的控制。
此时，冷冻室4内的实际的温度与包含装水制冰盘12的组件10存在于冰箱内的情况下的temp3相比，成为更高的temp2。在该较高温度的时刻停止压缩机52，因此冷冻室4内的温度不会从temp2下降，冷冻室4内的温度上升，温度传感器60的检测值也上升。然后，在温度传感器60的检测值达到上限值TH时，控制部100再次开始压缩机52的运行。于是，压缩机52的运行开始、停止且至下次运行开始为止的1个冷却循环结束。
由此，如图4的下侧的曲线图所示，冷冻室4内的温度从temp1下降至temp2，在压缩机52停止后，再次从temp2上升至temp1。为了进行贮藏于冷藏室4的食品的适当的冷冻保存，需要冷冻室4内的温度下降至temp3，但在包含装水制冰盘12的组件10不存在的情况下，仅下降至temp2，因此有可能无法进行食品的适当的冷冻保存。
(在下限值为特别设定值的情况下的冷却循环)
图5是表示下限值为特别设定值的情况下的温度传感器60的检测值以及冷冻室温度的曲线图，是表示即使在包含装水制冰盘12的组件10不存在于冰箱内的情况下也能实现与包含装水制冰盘12的组件10存在于冰箱内的情况同样的适当的冷冻室温度的控制的曲线图。
通过将下限值变更为比通常设定值更低的特别设定值，即使在包含装水制冰盘12的组件10不存在于冰箱内的情况下，也能在压缩机52的运行后，在冷冻室4内的温度从temp1下降至temp2后使下降继续。通过适当地规定作为进行使压缩机52的运行停止的控制的触发的特别设定值即下限值TL的值，从而在温度传感器60的检测值达到下限值TL(特别设定值)时，冷冻室4内的温度能成为temp3。图5之下的实线的曲线图示出了如此得到与图4的实线的情况下同样的适当的温度变化。
如上所述，在本实施方式中，控制部100在温度传感器60的检测值达到上限值时，开始压缩机52的运行，在温度传感器60的检测值达到下限值时，进行使运行中的压缩机52停止的控制，尤其在判断为包含装水制冰盘12的组件10不存在于冰箱内时，进行将下限值的值变更为比通常设定值更低的特别设定值的控制。由此，能提供即使在卸取了自动制冰装置40的包含装水制冰盘12的组件10的情况下也能实现冷冻室4内的适当的温度控制的冰箱2。
(包含装水制冰盘的组件的存在的有无的判断)
控制部100基于包含装水制冰盘12的组件10是否存在于冰箱内的判断，来决定是使用通常设定值还是使用特别设定值来作为下限值。由此，如何判断包含装水制冰盘12的组件10的存在的有无变得重要。关于包含装水制冰盘12的组件10的存在的有无的判断方法，以下详细描述。
＜第一实施方式所涉及的组件的存在的有无的判断方法＞
本发明的第一实施方式所涉及的组件10是否存在的判断方法是使用传感器进行检测的方法，例如能将检冰杆16用作该传感器。在包含装水制冰盘12的组件10存在于冰箱内的情况下，通过检冰杆16而得到某些检测信号，而在包含装水制冰盘12的组件10不存在于冰箱内的情况下，无法得到基于检冰杆16的检测信号，由此，能进行组件10的存在的有无的判定。另外，还能检测是否已电连接使装水制冰盘12旋转的旋转机构14的电动机，判定组件10的存在的有无。
进而，使用对包含装水制冰盘12的组件10是否存在进行检测的专用的接触式或者非接触式传感器，还能判定组件10的存在的有无。另外，例如，还能将如下开关用作接触式传感器：在组件10配置于冰箱内时，开关主体被按下而成为导通的状态，在组件10被卸取时，开关主体被释放而成为断开的状态。
如上所述，通过使用对包含装水制冰盘12的组件10是否存在于冰箱内进行检测的传感器，能可靠地判别包含装水制冰盘12的组件10是否存在，进行下限值的适当的设定。
＜第二实施方式所涉及的组件的存在的有无的判断方法＞
[判断为不存在组件的情况]
在本发明的第二实施方式所涉及的组件10是否存在的判断方法中，能不使用传感器而进行组件10是否存在的判断。
在包含装水制冰盘12的组件10存在于冰箱内的情况下，温度传感器60的检测值下降最快的是如下情况：冰箱2的周围温度低，在冷冻室4内无储藏物，门体6保持在闭合的状态。在此情况下，若将从压缩机52的运行开始起至温度传感器12的检测值达到下限值TL(通常设定值)为止的时间设为S1(参照图4)，则只要包含装水制冰盘12的组件10存在于冰箱内，温度传感器60的检测值达到下限值TL的时间就不会短于S1。
在冰箱2使用时，在冷冻室4内储藏有各种储藏物，为了储藏物的拿出放入，对冷冻室4的门体6进行开闭。在此情况下，温度传感器60的检测值达到下限值TL的时间有时会变长，但也有可能会变短。
另一方面，在包含装水制冰盘12的组件10被卸下而不存在于冰箱内的情况下，从出风口8吹出的冷气直接向温度传感器60流动，因此从压缩机52的运行开始起至温度传感器12的检测值达到下限值TL为止的时间必定短于S1。
因此，在本实施方式中，在至少1个冷却循环中，从压缩机52的运行开始起至温度传感器60的检测值达到下限值TL为止的时间短于给定的时间1时，控制部100判断为包含装水制冰盘12的组件10不存在于冰箱内。
由此，基于从压缩机52的运行开始起至温度传感器60的检测值达到下限值TL为止的时间，可以不使用特别的传感器判别包含装水制冰盘12的组件10是否存在。
作为用于判定的给定的时间1，还能使用在上述包含装水制冰盘12的组件10存在于冰箱内的情况下可能发生的最短时间S1。但不限于此，还能考虑不确定的变动因素，使用对该值施加给定的安全系数的值(小于S1的值)。
在本实施方式中，基于1个冷却循环的温度传感器60的检测值，能进行组件10是否存在的判断。但不限于此，还能考虑不确定的变动因素，在多个冷却循环中，在温度传感器60的检测值至达到下限值TL为止的时间短于给定的时间1时，判断为包含装水制冰盘12的组件10不存在于冰箱内。
[判断为存在组件的情况]
另一方面，从卸下了包含装水制冰盘12的组件10的状态起，安装于冰箱内的情况下的判断也需要。也就是，从下限值TL的值被设定为特别设定值的状态起，需要用于将下限值TL的值从特别设定值变更为通常设定值的判断处理。
作为该判断处理，例如可考虑如下方式：在多个冷却循环中，从压缩机52的运行开始起至温度传感器60的检测值达到下限值TL(特别设定值)为止的时间长于给定的时间2时，判断为包含装水制冰盘12的组件10存在于冰箱内。然后，控制部100基于该判断，将下限值TL的值从特别设定值变更为通常设定值。
在包含装水制冰盘12的组件10不存在于冰箱内的状态下，对将冷冻室4的门体6打开了一定时间的情况下的从压缩机52的运行开始起至温度传感器60的检测值达到下限值TL(特别设定值)为止的时间进行计测或者模拟，考虑将该时间或者对该时间乘以给定的安全系数后的值设为给定的时间2。
另外，作为给定的时间2，还能设为最近的N次冷却循环中的温度传感器60的检测值至达到下限值TL(特别设定值)为止的时间的平均值的K倍(例如，K＝1.2)。
在冷冻室4的门体6存在开闭的情况下，冷却循环的经过时间变动。由此，在判断为冷却循环处于稳定的状态时，考虑进行基于从压缩机52的运行开始起至温度传感器60的检测值达到下限值TL为止的时间的判断。
例如，认为在1个冷却循环的经过时间浮动于正负3％的范围内时判断为处于稳定状态。另外，在因冷藏室以及冷冻室4之间的风门(damper)的开闭而冷冻室4内的温度周期性变动的情况下，还认为在时间短的冷却循环以及时间长的冷却循环的各自的循环中，在冷却循环的经过时间浮动于正负3％的范围内时判断为处于稳定状态。
进而，在具备能对门体6的开闭进行探测的传感器的情况下，还能使用门体6不会被打开的冷却循环中的至达到下限值TL为止的时间，来判断组件10是否存在于冰箱内。
如上所述，在本实施方式中，在下限值TL的值被设定为特别设定值的状态下，在多个冷却循环中，从压缩机52的运行开始起至温度传感器60的检测值达到下限值TL(特别设定值)为止的时间长于给定的时间2时，判断为包含装水制冰盘12的组件10存在于冰箱内，并进行将下限值TL的值变更为通常设定值的控制。
由此，可以不使用特别的传感器判定包含装水制冰盘12的组件10从不存在的状态向存在的状态的变化，能将下限值TL的值确切地从特别设定值变更为通常设定值。
(与自动制冰装置有关的控制)
接下来，针对在判断为包含装水制冰盘12的组件10在冰箱内不存在时的自动制冰装置40的控制进行说明。假设在装水制冰盘12不存在于冰箱内的状态下， 在驱动泵24来供应贮水罐内的水的情况下，存在水向冷冻室4内泄漏的问题。
为了应对该状况，控制部100在判断为包含装水制冰盘12的组件10不存在于冰箱内时，进行控制处理使得泵24不运行。进而，为了避免多余的能量的消耗，进行控制使得卷绕于配管的外周的防冻加热器28也不运行。
如上所述，在判断为包含装水制冰盘12的组件10不存在于冰箱内时，进行不运行泵24以及防冻加热器28的控制，从而适当地防止包含装水制冰盘12的组件10不存在的状态下的不良状况，能抑制多余的能量消耗。
尽管说明了本发明的实施方式、实施形态，但公开内容可以在构成的细节上变化，实施方式、实施形态中的要素的组合、顺序的变化等能不脱离所请求的本发明的范围以及思想而能实现。
