在该实施例中，通过判断食品信息对应的食品类别，可以将食品进行分类，从相应的食品类别中获取对应的存储参数，例如：根据食品信息是否属于干货判断类别，比如茶、干山珍等需要干燥处理的为第一类别；需要一定湿度和加湿保鲜的，如菠菜等属于第二类别，每类食品信息对应于 自己的存储参数，即存储温度以及存储湿度，提高了食品存储参数的获取效率，进而提高了冰箱保鲜部的参数调整效率，实现在较短时间内使冰箱保鲜部内的食品处于较佳的保鲜状态。
其中，第一存储温度和第一存储湿度为判断为第一类别的食品信息对应的食品参数，即最佳保鲜条件，不同食品对应的食品参数可能相同，也可能不同；第二存储温度和第二存储湿度为判断为第二类别的食品信息对应的食品参数，即最佳保鲜条件，不同食品对应的食品参数可能相同，也可能不同；其中，食品的最佳保鲜参数(即存储参数)预设在冰箱的电脑控制板的芯片中。
如图2所示，在上述任一实施例中，优选地，确定与食品信息对应的存储参数，将冰箱保鲜部的参数调整为存储参数具体包括：若食品类别为第一类别，则执行步骤S2082，控制冰箱中的冷藏蒸发器化霜时采用加热管化霜模式进行除湿，直至冰箱保鲜部的湿度低于第一存储湿度，控制冰箱中的压缩机、冷藏侧电动阀、冷藏风门以及冷藏风机的开闭，直至冰箱保鲜部的温度为第一存储温度，其中，压缩机、冷藏侧电动阀、冷藏风门、冷藏风机均开启，冰箱保鲜部温度降低，压缩机、冷藏侧电动阀、冷藏风门、冷藏风机均关闭，冰箱保鲜部温度升高。
