延迟第二预设时间再开启所述压缩机，一方面，可以避免在化霜期间所述化霜加热装置所产生的高温气体进入压缩机内，对所述压缩机造成破坏；另一方面，可以防止因直接启动所述压缩机而使所述蒸发器表面化霜后产生的融霜水再次结冰，加速霜层积聚。
S2:开启所述压缩机、所述冷冻风机和所述冷藏风门，部分开启所述风机遮蔽装置，并判断是否满足预设的冷藏送风停止条件，若是，则进入冷冻制冷程序；
具体的，在本实施例中，判断是否满足预设的冷藏送风停止条件包括：获取冷藏室的实时冷藏温度，当实时冷藏温度小于预设的冷藏停止温度时进入冷冻制冷程序，所述冷藏停止温度为所述冷藏部设置的的工作温度区间的下限，满足所述冷藏停止条件即为此时所述冷藏部已冷却至其工作温度下限，而无需再继续制冷。
在本发明的另一些实施例中，所述冷藏送风停止条件也可包括：获取所述冷藏风门开启时长，当开启时长大于第五预设时间后进入冷冻制冷程序，所述第五预设时间满足所述冷藏部冷却至其工作温度下限所需的时长。
优选的，在步骤S4中，当所述冷冻风机启动后，所述风机遮蔽装置可依据所述化霜温度传感器所获取的实时温度，或是依据开启所述冷冻风机的时间，由关闭逐步调整为部分开启。所述风机遮蔽装置的开启档位可以是依靠算法实现随温度或时间变化的连续变化，也可以是通过几个预设的温度或时间的阈值，实现开启档位固定变化，诸如，在开启所述冷冻风机1分钟后，所述风机遮蔽装置开启1/3，在开启所述冷冻风机2分钟后，所述风机遮蔽装置开启1/2等。
通过将所述风机遮蔽装置设置为在化霜结束后的多档位变化，可随温度降低，将逐渐变多的风量送入到所述冷冻部内，以实现对所述冷冻部的动态预制冷，一方面，可以减小所述冷冻部的温度波动范围，并使温度变化更为平缓，有利于食品的储存；另一方面，可以减小后续步骤中对所述冷冻部制冷所需的功耗，降低耗电量。
S3:完全开启所述风机遮蔽装置，关闭所述冷藏风门，并判断是否满足预设的冷冻停止条件，若是，则关闭所述压缩机、所述冷冻风机和所述风机遮蔽装置。
具体的，在本实施方式中，判断是否满足预设的冷冻停止条件包括：获取冷冻室的实时冷冻温度，当实时冷冻温度小于预设的冷冻停止温度时，关闭所述压缩机、所述冷冻风机和所述风机遮蔽装置。所述冷冻停止温度为所述冷冻部所设置的工作温度区间下限，满足所述冷冻停止条件即为此时所述冷冻部已冷却至其工作温度下限，而无需再继续制冷。
在本发明的另一些实施方式中，断是否满足预设的冷冻停止条件也可包括：获取所述风机遮蔽装置完全开启时长，当完全开启时长满足第六预设时间后，关闭所述压缩机、所述冷冻风机和 所述风机遮蔽装置，所述第六预设时间满足所述冷冻部冷却至其工作温度下限所需的时长。
如图3所示，为本发明提供一种化霜控制方法的第二实施例的流程示意图，在该第二实施例中，所述化霜控制方法的步骤S1～步骤S3与第一实施例中相同，在此不再赘述；其不同在于，在步骤S1之前还包括步骤S0：
判断冰箱满足化霜条件后，关闭压缩机和风机遮蔽装置，并保持冷藏风门开启，运行冷冻风机至第一预设时间后关闭所述冷冻风机及所述冷藏风门，进入化霜程序。
于关闭所述冷冻风机之前，开启所述冷藏风门。此时所述压缩机未工作，其周围的温度相较于所述冷冻部所需的制冷温度产生回升，但依然能够满足所述冷藏部的制冷温度需求，开启所述冷藏风门以对所述冷藏部进一步制冷。并且，通过设置所述第一预设时间来对所述冷冻风机进行限制，在所述第一预设时间内，温度回升可控制在一定范围内，而不会造成所述冷藏部温度过高。同时，通过关闭所述风机遮蔽装置，以防止所述冷冻部温度上升。从而，通过上述步骤，可以对满足冷藏制冷需求的风量进行更有效地利用，降低能耗的同时也不会对所述冷冻部造成影响。
如图4所示，为本发明提供一种化霜控制方法的第三实施例的流程示意图，在该第三实施例中，所述化霜控制方法的步骤S0～步骤S3与第二实施例中相同，在此不再赘述；其不同在于，在步骤S3之后还包括步骤S4～步骤S6：
S4：判断是否满足预设的冷藏开启条件，若是，则进入下一步骤；若否，则继续关闭所述压缩机、所述冷冻风机、冷藏风门和所述风机遮蔽装置。
S5：开启所述压缩机、所述冷冻风机和所述冷藏风门，关闭所述风机遮蔽装置。
在本实施方式中，所述冷藏开启条件为包括：获取冷藏室的实时冷藏温度，判断实时冷藏温度大于预设的冷藏开启温度时，关闭所述压缩机、所述冷冻风机、冷藏风门和所述风机遮蔽装置。所述冷藏开启温度为所述冷藏部所设置的工作温度区间上限，从而可通过所述冷藏开启温度和所述冷藏停止温度限定所述冷藏部的工作温度区间，满足所述冷藏开启条件即为此时所述冷藏部已回温至其工作温度上限，需对所述冷藏部重新制冷。
S6:判断是否满足预设的冷冻开启条件，若是，则重复进入步骤S3，若否，则关闭所述压缩机、所述冷冻风机、所述冷藏风门和所述风机遮蔽装置。
在本实施方式中，所述冷冻开启条件包括：获取冷冻室的实时冷冻温度，判断实时冷冻温度大于预设的冷冻开启温度时，重复进入步骤S3。所述冷冻开启温度为所述冷冻部所设置的工作温度区间上限，从而可通过所述冷冻开启温度和所述冷冻停止温度限定所述冷冻部的工作温度区间，满足所述冷冻开启条件即为此时所述冷冻部已回温至其工作温度上限，需所述冷冻部重新制冷。
通过步骤S4～步骤S6的循环交替确认，可确保所述冰箱在化霜结束后所述冷藏部和所述冷冻部在正常工作温度区间。
综上所述，本发明的具有风机遮蔽装置的冰箱的化霜控制方法，在化霜步骤前后不同阶段，根据制冷系统和化霜加热装置的工作状态，调整风机遮蔽装置为开启、关闭及部分开启的多个不同档位，以控制冰箱在化霜前后实现制冷或加热的不同方法模式，从而能够降低化霜过程中的温度回升，并使冷冻部在化霜前后的温度波动更小，温度变化平缓，提高制冷效果，从而降低能耗。
