如图1-图3所示，本公开一些实施例提供了一种内置有制冰机3的冰箱，制冰机3设置于冰箱的冷藏室2内，制冰机3连通的水源为冰箱内置水源，内置水源为冷藏室2内设有的储水箱4，其中，储水箱4与制冰机3的连通方式是：储水箱4通过三通阀7与水管5连接。
如图4-图5所示，本公开一些实施例提供了一种内置有制冰机3的冰箱，制冰机3设置于冰箱的冷藏室2内，制冰机3连通的水源为外接水源8，外部水源的供水路径分为两路：其中第一路供水路径外部水源通过水管5依次与过滤器9、三通阀7、制冰机3连接；第二路路供水路径外部水源通过水管5依次与过滤器9、三通阀7、储水罐10、饮水机6连接。即三通阀7前一段的供水路径为第一路供水路径和第二路供水路径的共同路径，三通阀7之后一段按照不同的供水目标分为两组路径。
根据本公开一些实施例中一种冰箱，包括：箱体1、水管组件、加热组件和控制器，箱体1内设置有冷藏室2；水管组件设置于冷藏室2内；加热组件也设置于冷藏室2内，用于加热水管组件以防止水管组件冻结；控制器被配置为检测当前冰箱外部环境温度，当环境温度低于控制器预设温度时，控制相应的加热组件对水管5进行不同方式的间歇性加热。
根据本公开一些实施例中一种冰箱，设定冷藏室2温度范围为1～8℃，环境温度为0～43℃，当环境温度低时，环境温度与冷藏室2的温差小，冷藏热负荷较小，冷藏室2降温至设定档位时间缩短，并且当电动风门开启后，热负荷小、此时受冷冻设定温度影响，送风温度是-14～-24℃，冷藏温度很快达到设定，甚至更低，产生局部负温的现象，从而增加冷藏室内水管冻结可能。冷冻送到冷藏室2的风为-14～-24℃，本实施例通过送风管连接冷藏冷冻室，冷冻的风经过送风管、电动风门后进入冷藏室2。冷藏室2与冷冻的间隔是电动风门，由于冷藏室2与冷冻存在巨大温差，根据热力学第二定律，冷 藏冷冻会进行热交换，导致冷藏温度降低，冷冻温度升高，温差逐渐降低，从而产生局部负温的现象，容易造成冷藏室内水管冻结。
为避免水管组件发生冻结，根据控制器检测到的环境温度，再根据该环境温度下对应的冷藏冷冻温度，控制相应的加热组件进行不同加热方式的间歇性加热，以达到不同的加热效果，最终实现冷藏室2内的水管组件内水温保持在0℃以上，避免水管组件发生冻结。
本公开一些实施例中，加热组件包括第一加热器11和第二加热器12。图7是根据一些实施例的冰箱的第一加热器结构示意图。如图7所示，第一加热器11为冷藏室2与冷冻室之间的翻转梁加热器，第一加热器11包括翻转主杆111、加热丝112和金属面板113，翻转主杆111与金属面板113连接，加热丝112嵌于翻转主杆111和金属面板113之间。图6是根据一些实施例的冰箱的制冰机结构侧视图。如图6所示，第二加热器12位于制冰机3注水口处，如图8所示，第三加热器13设置于注水管14上，加热功率设定为2W，控制器被配置为：检测当前环境温度Th，当9℃≤Th≤14℃时，控制所述第一加热器11进行间歇性加热；当Th＜9℃时，对应控制所述第一加热器11和所述第二加热器12同步进行间歇性加热，以及第三加热器13单独针对制冰机注水口进行间歇加热。
Figure PCTCN2021125939-appb-000001
表1
如上表1所示，控制器被配置为根据不同的环境温度，选择对应的加热方式，采取不同的加热器进行加热。当加热组件采用第一加热器11间歇加热的方式，控制第一加热器11的加热时间为120秒～680秒，第一加热器11每次加热完成后停止运行120秒；当加热组件采用第一加热器11和第二加热器12同步间歇加热的方式时，设定第一加热器11和第二加热器12同步启动加 热680秒，同步停止运行120秒。
当控制器检测到环境温度处于9℃≤Th≤14℃时，控制器选择采取第一加热器11间歇加热的方式，此时控制器先对冷藏室2的冷藏室温度以及运行档位进行检测，其中冷藏室2运行档位与对应的冷藏室2温度和冷冻温度相对应，运行档位越高对应的冷藏室2温度和冷冻温度越低。根据每组档位和冷藏冷冻温度的不同对应关系，控制器相应的控制第一加热器11进行不同时长的加热，以防止加热过多或加热不足的情况发生，保证了第一加热器11的加热效果适配不同的冷藏室2、冷冻室温度情况。示例性的，运行档位和冷藏室冷冻室温度的对应关系见表2。
冷藏室温度 运行档位 冷冻室温度 启动加热时间 停止加热时间 加热比例
8℃ 8 高于18℃ 120秒 120秒 50％
7℃ 7 高于18℃ 180秒 120秒 60％
6℃ 6 高于18℃ 230秒 120秒 66％
5℃ 5 高于18℃ 280秒 120秒 70％
4℃ 5 高于18℃ 360秒 120秒 75％
3℃ 5 高于18℃ 480秒 120秒 80％
2℃ 5 高于18℃ 550秒 120秒 82％
1℃ 5 高于18℃ 680秒 120秒 85％
表2
为了避免冷桥影响过大，档位设置过低，此时除了启动加热组件进行加热补偿，还将采用第一加热器11和第二加热器12之间不同的加热比例方式运行，以满足冷藏室2温度需求，同时还要对冷冻的最冷档位进行限制，当运行档位对应的冷冻设定温度低于-18℃时，冷冻的实际开停档位都按照-18℃对应的运行档位运行，目的是避免冷冻档位设定过低，对冷藏室的温度影响过大。
当环境温度Th＜9℃时，冷藏室2的冷藏温度开始出现负温，启动加热组件进行加热补偿，同时对冷冻室的最冷设定档位进行限制。此时冷藏室2的设定档位不再起作用，直接按冷藏室2对应5℃设定档位的开停点进行控制。为防止第一加热器11不足以将冷藏室2内的水管组件升至正温，同时需要启 动第二加热器12进行加热，第一加热器11与第二加热器12进行并联，两个加热器的控制方案一致。另外，为了避免加热器一直加热容易产生故障，因此设定为间歇性加热。
本公开一些实施例中，还包括制冰机3和注水管14，制冰机3安装于冷藏室2内，注水管14设置于箱体1的顶部与制冰机3连通；控制器被配置为：检测当前环境温度Th，当Th＜9℃时，检测制冰机的工作模式，根据工作模式匹配第三加热器13对应的间歇性加热时间。
制冰机3内设置有制冰室，当制冰机3处于制冰模式时，整个制冰室的温度处于-12℃～-2℃，此时控制器控制第三加热器13开始加热5分钟，加热5分钟后停止运行4分钟，按照该方式循环开启，以保证低环境温度时的正常制冰需求。
当制冰机处于储冰模式时，整个制冰室都处于-12℃～-2℃左右，此时控制器控制第三加热器13开始加热3分钟，加热3分钟后停止运行4分钟，按照该方式循环开启，以保证低温下注水管14内的水能正常流动，为下一次制冰提供保障。
综上所述，本实施例在冰箱内部原有加热器的基础上，通过增加的新的控制规则，使得冷藏室2及注水管温度升高至新设定温度；同时控制方法还包括对设定温度的调整，避免更低环境温度下，设定温度过低引起制冰及出水故障。
以上所述仅是本公开的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本公开的保护范围。
