Description

冰箱的制冰方法及冰箱 技术领域
本发明涉及制冷制冰技术领域，特别是涉及一种冰箱的制冰方法及冰箱。

步骤S102，使制冰间室内的温度高于或等于第一预设值，以防止制冰间室内由于刚完成制冰导致温度过低，不利于制冰。
步骤S104，向制冰间室内的制冰容器中注水。
步骤S106，按照第一制冷能力向制冰间室内提供冷量，且使制冰间室内的温度依次下降达到多个第一预设温度，且在制冰间室内的温度下降达到每个第一预设温度时，使制冰间室内的温度在该第一预设温度处保持对应的第一预设时长。相邻的两个第一预设温度中，较低的第一预设温度对应的第一预设时长小于较高的第一预设温度对应的第一预设时长。
在本发明的一些进一步的实施例中，如图2所示，冰箱的制冰方法还包括：
步骤S108，在制冰间室内的温度继续下降达到第二预设温度时，使制 冰间室内的温度在第二预设温度处保持第二预设时长。
步骤S110，按照第二制冷能力向制冰间室内提供冷量，且使制冰间室内的温度依次下降达到多个第三预设温度，且在制冰间室内的温度下降达到每个第三预设温度时，使制冰间室内的温度在该第三预设温度处保持对应的第三预设时长。相邻的两个第三预设温度中，较低的第三预设温度对应的第三预设时长小于较高的第三预设温度对应的第三预设时长。第二制冷能力大于第一制冷能力。
本发明实施例的冰箱的制冰方法中，能够尽可能地将水中的空气排出，具体地先使制冰间室内的温度升高，然后通过控制第一制冷能力和/或第二制冷能力的开机率缓慢冷却的方式让空气有机会排出，不至于空气被冰封住形成空隙；而且温度越高冷却速度越慢，温度越低冷却速度越快，能够让水温度缓慢变化，使水的温度整体上趋于一致，减少水面与水内部的温差，还有就是可以让水中的空气逸出，避免了急速冷冻导致的空气被封在冰块中，尽可能使冰块达到透明，甚至于能够制造出完全透明的美观冰。
在本发明的一些实施例中，如图2所示，冰箱的制冰方法还包括步骤S112：在制冰间室内的温度继续下降达到第四预设温度时，使制冰间室内的温度在第四预设温度处保持第四预设时长，可确保制冰完全，确保冰完全凝结。
图3示出了根据本发明另一个实施例的冰箱的制冰方法的示意性流程图。
在一些实施例中，为了进一步提高排出空气效率，进入制冰容器中的水的温度高于或等于第二预设值。如图3中步骤S204所示，通过加热向制冰容器内供水的进水管使进入制冰容器中的水的温度高于或等于第二预设值。例如，进水管与冰箱的冷凝器热连接，以使冷凝器加热进水管中的水。进水管与冷凝器缠绕。本发明实施例的冰箱的制冰方法中还通过加热的方式排除空气，可提高制冰效率和效果。也即是说，从外界注入制冰机的水，先通过进水管流入制冰机中，该进水管与冷凝器缠绕，在水流进入过程中会被冷凝器加热，水中空气会被排除一部分，然后被加热的水在注入到制冰机的制冰容器如冰格中。
在本发明的一些实施例中，如图3中步骤S202所示，通过使制冰间室与外界环境相通，使制冰间室内的温度上升，达到或高于第一预设值。即在 制冰容器注水之前，或刚完成脱冰，将制冰间室与外界环境(室温)相通，使制冰间室温度上升。
在本发明的一些实施例中，如图3所示，在步骤S206中，第一制冷能力为冰箱的冷藏室或冷藏室用蒸发器提供的制冷能力。具体地，冰箱的冷藏室用蒸发器向制冰间室内提供冷量，且使制冰间室内的温度依次下降达到多个第一预设温度，且在制冰间室内的温度下降达到每个第一预设温度时，使制冰间室内的温度在该第一预设温度处保持对应的第一预设时长。相邻的两个第一预设温度中，较低的第一预设温度对应的第一预设时长小于较高的第一预设温度对应的第一预设时长。
在步骤S210中，第二制冷能力为冰箱的冷冻室或冷冻室用蒸发器提供的制冷能力。具体地，冰箱的冷冻室用蒸发器向制冰间室内提供冷量，且使制冰间室内的温度依次下降达到多个第三预设温度，且在制冰间室内的温度下降达到每个第三预设温度时，使制冰间室内的温度在该第三预设温度处保持对应的第三预设时长。相邻的两个第三预设温度中，较低的第三预设温度对应的第三预设时长小于较高的第三预设温度对应的第三预设时长。
步骤S208和步骤S212分别与前文步骤S108和步骤S112相同。第二预设温度等于冰箱的冷藏室内的目标温度。第四预设温度等于冰箱的冷冻室内的目标温度。
进一步地，每两个相邻的第一预设温度之间的差值相等。每两个相邻的第一预设温度之间的差值为0.8℃至1.5℃，优选为1℃。每两个相邻的第一预设温度之间的差值等于最低的第一预设温度与第二预设温度之间的差值。每两个相邻的第三预设温度之间的差值相等。每两个相邻的第三预设温度之间的差值为0.8℃至1.5℃，优选为1℃。
在该实施例中，具体通过控制冷藏室用蒸发器和冷冻室用蒸发器的开机率缓慢冷却的方式让空气有机会排出，不至于空气被冰封住形成空隙。当刚注入水时，制冰间室温度与室温一致，此时制冰间室与冷藏室温差较大，让制冰冷藏风机开机率最低，温度每下降1摄氏度，都要维持T时刻，随着温差减小，冷藏风机开机率逐渐加大，可让水温度缓慢变化，使水的温度整体上趋于一致，减少水面与水内部的温差，可以让水中的空气逸出，避免了急速冷冻导致的空气被封在冰块中。同样地，当冷冻室用蒸发器开始制冷时，制冰间室温度与冷藏室温一致，此时制冰间室与冷冻室温差较大，让制冰冷 冻风机开机率最低，温度每下降1摄氏度，都要维持T时刻，随着温差减小，冷冻风机开机率逐渐加大，可让水温度缓慢变化，使水的温度整体上趋于一致，减少水面与水内部的温差，可以让水中的空气逸出，避免了急速冷冻导致的空气被封在冰块中。
在本发明的一些实施例中，如图3所示，冰箱的制冰方法还包括脱冰步骤S214，将制冰容器中制作完成的冰从制冰容器中脱离，进入储冰容器中。例如，脱冰是将冰从制冰间室搬移到储冰室中。
本发明实施例还提供了一种冰箱，包括制冰装置、制冰间室、间室加热单元、水加热单元和制冷装置。制冰间室为单独空间单元，不与其他空间直接相通，并有良好的保温材料制作。制冰装置具有设置于制冰间室内的制冰容器，制冰容器可为冰格、冰盒等。制冰装置通过向冰盒内注水，在制冰间室的冷环境中将水凝结成冰，并翻冰到储冰室的储冰盒中。即储冰室用于储存从制冰装置里制出的冰，储冰室与冷冻室相连。
间室加热单元配置成在向制冰容器内供水前，使制冰间室内的温度高于或等于第一预设值。水加热单元配置成使进入制冰容器中的水的温度高于或等于第二预设值。制冷装置配置成：按照第一制冷能力向制冰间室内提供冷量，且使制冰间室内的温度依次下降达到多个第一预设温度，且在制冰间室内的温度下降达到每个第一预设温度时，使制冰间室内的温度在该第一预设温度处保持对应的第一预设时长。相邻的两个第一预设温度中，较低的第一预设温度对应的第一预设时长小于较高的第一预设温度对应的第一预设时长。以及在按照第一制冷能力向制冰间室内提供冷量后，按照第二制冷能力向制冰间室内提供冷量，且使制冰间室内的温度依次下降达到多个第三预设温度，且在制冰间室内的温度下降达到每个第三预设温度时，使制冰间室内的温度在该第三预设温度处保持对应的第三预设时长。相邻的两个第三预设温度中，较低的第三预设温度对应的第三预设时长小于较高的第三预设温度对应的第三预设时长。第二制冷能力大于第一制冷能力。
在本发明的一些实施例中，冰箱还包括进水管、冷凝器、冷藏室用蒸发器和冷冻室用蒸发器，进水管用于向制冰容器内供水。
间室加热单元为环境连通装置，配置成在进水管进水前，受控地使制冰间室与冰箱外空间连通。环境连通装置可具有环境风门，可通过控制环境风门的开闭使制冰间室与冰箱外空间连通或断开。在本发明的一些替代性实施 例中，也可用加热装置加热制冰间室。
水加热单元为上述冷凝器，冷凝器与进水管热连接，例如进水管缠绕于冷凝器。在本发明的一些替代性实施例中，也可用电加热丝缠绕于进水管进行加热，或者在储水箱中对水进行加热。
制冷装置包括上述冷藏室用蒸发器和上述冷冻室用蒸发器，冷藏室用蒸发器和冷冻室用蒸发器均配置成受控地向制冰间室提供冷量，且冷藏室用蒸发器的制冷能力为第一制冷能力，冷冻室蒸发器的制冷能力为第二制冷能力。进一步地，可通过风门和风路选择冷藏室用蒸发器向冰箱的冷藏室制冷还是向上述制冰间室制冷，可通过风门和风路选择冷冻室用蒸发器向冰箱的冷冻室制冷还是向上述制冰间室制冷。在本发明的一些替代性实施例中，也可设置专门的制冰蒸发器，直接控制制冰蒸发器使其在不同的步骤具有不同的制冷能力。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
