Description

控制冰箱储存空间湿度的方法及装置、冰箱、存储介质 技术领域
本发明涉及家用电器领域，具体地涉及控制冰箱储存空间湿度的方法及装置、冰箱、存储介质。

现有技术中，有部分冰箱在制冷空间内设置保湿抽屉来储存果蔬，设置风干抽屉来保存干燥的一些食材，也有一些冰箱采用可调节湿度的空间来保存不同湿度需求的食材。
专利申请公开号第CN106052296A号公开了一种可识别果蔬种类的智能保鲜冰箱的控制方法，包括以下步骤：1)、压力传感器检测保鲜室内部所放置的果蔬的重量；2)、湿度传感器检测保鲜室内部的湿度；3)、摄像头对保鲜室内的果蔬进行拍照，图形处理器获取所拍摄图像的颜色特征值和形状特征值，中央处理器根据将该颜色特征值和形状特征值与数据存储器中存储的特征值进行对比，对果蔬进行识别；4)、中央处理器根据压力传感器的检测值以及果蔬识别结果，个别地控制七彩保鲜灯的开闭及亮度，从而对不同的果蔬实施不同的光照处理；当湿度传感器所检测的湿度值低于一预设值时，中央处理器控制喷雾装置，以对果蔬室内部的果蔬实施一喷雾处理。
但是，上述现有技术的方案都没有考虑到食材混放的情况，如果用户在一个空间内放了多种不同种类的食材，上述现有技术的方案将无法判断应将存储空间的湿度控制为哪种食材的最佳保存温度。

附图说明
附图是用来提供对本发明实施例的进一步理解，并且构成说明书的一部分，与下面的具体实施方式一起用于解释本发明实施例，但并不构成对本发明实施例的限制。在附图中：
图1是根据本发明一实施例的控制冰箱储存空间湿度的方法的流程图；
图2是根据本发明另一实施例的控制冰箱储存空间湿度的方法的流程图；
图3是根据本发明另一实施例的控制冰箱储存空间湿度的方法的流程图；
图4是根据本发明另一实施例的控制冰箱储存空间湿度的装置的结构框图；以及
图5是根据本发明另一实施例的控制冰箱储存空间湿度的装置的结构框图。
具体实施方式
以下结合附图对本发明实施例的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明实施例，并不用于限制本发明实施例。
图1是根据本发明一实施例的控制冰箱储存空间湿度的方法的流程图。如图1所示，该方法包括以下步骤：
在步骤S101中，确定储存空间中储存的食材的种类。
所述食材的种类例如可以由用户通过输入模块输入，也可以由如背景技术中所描述的利用图像识别方法来确定食材种类的技术来确定。为了节约冰箱控制的运算量，可在应用该方法的冰箱上设置输入装置，用户在向冰箱中放入食材时，可通过输入装置录入食材的种类等信息。
在步骤S102中，确定储存空间中储存的食材是否只有一种。
在步骤S103中，当所述储存空间储存有一种食材时，将所述储存空间的湿度控制为该食材的最佳保存湿度值。
此时，因为储存空间中只储存有一种食材，所以只需考虑该食材的最佳保存湿度值，该食材的最佳保存湿度值可以从该食材的最佳保存湿度范围中选取，优选为其最佳保存湿度范围的中间值。
在步骤S104中，当所述储存空间储存有多种食材时，根据所述多种食材中的每一种食材的最佳保存湿度值控制所述储存空间的湿度。
此时，需要综合考虑各种食材所适应的湿度环境，以确定能够使混放的多种食材总体上达到最佳保鲜效果的湿度。
图2是根据本发明另一实施例的控制冰箱储存空间湿度的方法的流程图。在图2中，步骤S201-S203分别同步骤S101-步骤S103，此处不再赘述。
如图2所示，该方法还可以优选地包括以下步骤：
在步骤S204中，确定所述每一种食材的最佳保存湿度值。
在步骤S205中，从所述多种食材的最佳保存湿度值中确定出最大值和最小值。
在步骤S206中，确定所述最大值是否等于所述最小值。
在步骤S207中，当所述最大值等于所述最小值时，将所述储存空间的湿度控制为所述最大值或所述最小值。
如果所述最大值等于所述最小值，则说明储存空间内食材的种类虽然不同，但各种食材所适应的湿度环境相同，是属于相似类型的食材，因此，可将储存空间的湿度控制为所述最大值或所述最小值，由此为所有的食材提供最佳湿度储存环境。
在步骤S208中，当所述最大值不等于所述最小值时，根据所述最大值、所述最小值以及预设湿度控制所述储存空间的湿度。此时，储存空间内储存的各种食材所适应的湿度环境不同，需要进一步综合考虑所述最大值和所述最小值，并引入预设湿度来控制冰箱储存空间内的湿度。
图3是根据本发明另一实施例的控制冰箱储存空间湿度的方法的流程图。在图3中，步骤S301-S307分别同上述步骤S201-S207，因此不再赘述。
如图3所示，该方法可优选地包括以下步骤：
其中，在步骤S308和S310中，比较所述最大值和所述最小值与所述预设湿度。在步骤S308中判断所述预设湿度是否大于所述最大值，如果不是，则进一步在步骤S310中判断所述预设湿度是否小于所述最小值。
在步骤S309中，当所述最大值小于所述预设湿度时，将所述储存空间的湿度控制为低档位湿度。
在步骤S311中，当所述最小值大于所述预设湿度时，将所述储存空间的湿度控制为高档位湿度。
在步骤S312中，当所述预设湿度为所述最小值与所述最大值之间时， 将所述储存空间的湿度控制为所述预设湿度。
假设预设湿度为H，H的取值范围为0％RH＜H＜100％RH，并假设所述最大值为Hmax，所述最小值为Hmin。可将储存空间的湿度区分为三个档位：高档位湿度HU，HU的值可以在H和100％RH之间，适用于果蔬类等喜湿食材；低档位湿度HL，HL的值可以在0％RH和H之间，适用于易吸潮发霉的干燥食材；中间档位H，当储存空间内湿度均值控制在中间档位H时，适用于一些不易挥发水份的根茎类食材以及一些熟食等，并且可同时兼顾喜湿类食材或者干燥食材。
在Hmax≠Hmin时，则首先判定Hmax是否小于预设湿度H，若小于则说明所有食材所适应的湿度环境均处于低档位湿度内，则判定当前空间内湿度控制为低湿档位HL；若不小于则接着判断Hmin是否大于预设湿度H，若大于则说明所有食材所适应的湿度环境均处于高档位湿度HU内，则判定当前空间内湿度控制为高档位湿度HU；若是Hmin≤H≤Hmax，则说明当前空间内食材有喜湿类食材也有干燥类食材，可判定当前空间湿度控制于中间湿度档位H，以兼顾所有食材的保存效果。
其中，所述预设湿度H的取值范围优选为60％-75％RH。
在其他实施例中，当所述低档位湿度优选为小于所述预设湿度，所述高档位湿度优选为大于所述预设湿度。
其中，所述食材的最佳保存湿度值优选为该食材的最佳保存湿度范围的中间值。为了对此进行说明，在表1中示例性地列举了一些食材的最佳储存湿度范围。对于每种食材来说，都存在有利于该种食材保鲜的最佳湿度储存范围，例如，坚果类的最佳湿度保存范围为65-75％RH，干燥果肉的最佳保存湿度范围为50-60％RH，可以选取每种食材的最佳保存湿度范围的中间值作为其最佳保存湿度值。例如，坚果类的最佳保存湿度值为67.5％RH，干燥果肉为55％RH。
表1：
Figure PCTCN2017090798-appb-000001
当冰箱储存空间中混放了如表1所示的多种食材时，所述最大值为97.5％RH，所述最小值为40％RH，假设此时预设湿度值为65％RH，则40％RH<65％RH<97.5％RH，说明此时储存空间内储存的各种食材所湿应的湿度环境有喜湿性的也有喜干性的，可优选地将储存空间的湿度控制为预设湿度65％RH。
当冰箱中只储存了干燥果肉和牛奶巧克力时，所述最大值为55％RH，所述最小值为40％RH，55％RH<65％RH，所述最大值小于预设湿度，因此可将储存空间的湿度控制为低档位湿度，此时，低档位湿度可以是所述最大值和所述最小值的中间值，也可优选为所述最小值，即40％RH。
当冰箱中储存有西葫芦、土豆和油菜时，所述最大值为97.5％RH，所述最小值为72.5％RH，65％RH<72.5％RH，所述最小值大于预设湿度，因此可将储存空间的湿度控制为高档位湿度，此时，高档位湿度可以是所述最大值和所述最小值的中间值，也可优选为所述最大值，即97.5％。
图4是根据本发明另一实施例的控制冰箱储存空间湿度的装置的结构框图。如图4所示，该装置包括：确定模块10，用于确定储存空间中储存的食材的种类；控制模块20，用于：当所述储存空间储存有一种食材时，将所述储存空间的湿度控制为该食材的最佳保存湿度值；当所述储存空间 储存有多种食材时，根据所述多种食材中的每一种食材的最佳保存湿度值控制所述储存空间的湿度。
所述控制模块20还可以用于：确定所述每一种食材的最佳保存湿度值；从所述多种食材的最佳保存湿度值中确定出最大值和最小值；当所述最大值等于所述最小值时，将所述储存空间的湿度控制为所述最大值或所述最小值；当所述最大值不等于所述最小值时，根据所述最大值、所述最小值以及预设湿度控制所述储存空间的湿度。
图5是根据本发明另一实施例的控制冰箱储存空间湿度的装置的结构框图。如图5所示，该装置还可以包括：比较模块，用于比较所述最大值和所述最小值与所述预设湿度。
此时，所述控制模块20还可以用于：当所述最大值小于所述预设湿度时，将所述储存空间的湿度控制为低档位湿度；当所述最小值大于所述预设湿度，将所述储存空间的湿度控制为高档位湿度；当所述预设湿度为所述最小值与所述最大值之间时，将所述储存空间的湿度控制为所述预设湿度。
其中，所述低档位湿度优选为小于所述预设湿度，所述高档位湿度优选为大于所述预设湿度。
其中，所述预设湿度的取值范围优选为60％-75％RH。
其中，所述食材的最佳保存湿度值优选为该食材的最佳保存湿度范围的中间值。
在另一实施例中，还提供一种冰箱，该冰箱包括上述内容中所述的控制冰箱储存空间湿度的装置。该冰箱还可以包括输出装置或输入输出端口，以使用户录入食材的种类，或同时显示所储存的食材。
在其他实施例中，还提供一种机器可读存储介质，该机器可读存储介质上存储有指令，该指令用于使得机器执行上述内容中所述的控制冰箱储存空间湿度的方法。
以上结合附图详细描述了本发明例的可选实施方式，但是，本发明实施例并不限于上述实施方式中的具体细节，在本发明实施例的技术构思范围内，可以对本发明实施例的技术方案进行多种简单变型，这些简单变型均属于本发明实施例的保护范围。
