图中：
1、干衣筒；2、湿度传感器；3、检测装置。
具体实施方式
下面结合附图并通过具体实施方式来进一步说明本发明实施例的技术方案。
实施例一
相关技术中的干衣机，衣物的湿度通过设置于衣物投放口的湿度传感器检测。在衣物烘干过程中，随着干衣筒不断的转动，衣物频繁与该湿度传感器接触，由于衣物的湿度与衣物阻抗值之间存在反比例关系，该湿度传感器通过检测衣物的阻抗值得到衣物的湿度。当衣物湿度高时，湿度传感器检测到的衣物的阻抗值小；当衣物湿度低时，湿度传感器检测到的衣物的阻抗值大。另外，相关技术中的干衣机，由于衣物在干衣筒内会有缠绕，位于外部的衣物烘干快，而缠绕在内部的衣物烘干慢，相对湿度大，会出现衣物烘干不均匀的问题。
并且，相关技术中的干衣机，干衣筒中的衣物量也会影响衣物烘干效果，当干衣筒中放入的待烘干衣物量较多时，经过烘干后的衣物经常会有褶皱现象产生。而当干衣筒中放入的待烘干衣物量较少时，衣物容易贴在干衣筒内壁上，从而衣物产生褶皱。例如额定烘干容量8kg的干衣机，放入6kg以上的衣物烘干时，尤其是放入的衣物大多为棉纤维类材料时，衣物的褶皱痕迹会明显且不易舒展开；当放入小于3kg的衣物烘干时，在烘干过程中衣物贴在干衣筒的内壁上，衣物也会产生褶皱现象。
如图1所示，是本实施例提出的干衣机，包括干衣筒1，干衣筒1的衣物投放口11设置有检测衣物湿度值的湿度传感器2，湿度传感器2设置为对干衣筒1中的衣物的湿度进行检测，并将湿度值传递给控制器。其中，可选地，湿度传感器由一对金属电极组成。
干衣筒1中还设置有检测装置3，检测装置3设置于干衣筒1的内侧，可选地，检测装置3可设置在干衣筒1的衣物投放口的边缘处。如图1所示，检测装置3设置在朝向干衣筒1的衣物投放口的内壁上，在干衣筒1转动过程中衣物能够与检测装置3相接触。作为一种可选的实施方式，本实施例中的检测装置3为一对金属电极，可选为一对金属条电极。
此外，检测装置3与控制器电连接，检测装置3设置为在干衣筒1转动过程中，不断检测该检测装置周围环境的阻抗值，控制器在预定时间内每间隔一预设时间段获取检测装置检测得到的阻抗值。其中，预定时间和预设时间段均可以根据干衣筒的容量进行适当的调整，可选地，本实施例中的预定时间为3分钟，预设时间段为0.4s-0.6s，可选为0.4s，即每间隔0.4s控制器获取检测装置3检测周围环境中的阻抗值，之后，控制器将3分钟内获取到的所有阻抗值分别于阻抗阈值进行比较，以根据比较结果判定干衣筒的衣物量。当检测装置3与衣物接触时检测的就是衣物的阻抗值，当检测装置3与空气接触时，检测的就是空气中的阻抗值。
作为可行的实施方式，检测装置3设置在衣物投放口11所在平面的水平对称轴的上方，可选地，检测装置设置在衣物投放口11所在平面的水平对称轴的上方、竖直对称轴向左或向右偏转60°的范围内。当干衣筒1朝向顺时针方向 旋转时，检测装置3设置在衣物投放口所在平面的水平对称轴的上方、竖直对称轴向左偏转60°的范围内，即设置在10点钟-12点钟方向范围内，可选设置在10点钟位置。当干衣筒1朝向逆时针方向旋转时，检测装置3设置在衣物投放口所在平面的水平对称轴的上方、竖直对称轴向右偏转60°的范围内，即设置在2点钟-12点钟方向范围内，可选设置在2点位置。
其中，将检测装置3分别设置在10点钟-12点钟范围内或设置在2点钟-12点钟范围内的原因是：在干衣筒1旋转过程中，衣物受离心力作用，在上述两个范围内设置的检测装置与衣物接触的机会最多。由于干衣筒1中的衣物数量与检测装置3和衣物接触的次数值呈正线性分布，检测装置与衣物接触的机会多，控制器可根据检测装置检测得的阻抗值较准确地判定干衣筒中的衣物量，从而合理地调整干衣筒的转速。。
在实施过程中，湿度传感器2和检测装置3可以同时选用一样(如材质和/或形状等一样)的金属电极，在使用过程中，湿度传感器2的金属电极设置在干衣筒1的衣物投放口所在平面水平对称轴边缘的下部。干衣机工作过程中，衣物在重力作用下会下落至干衣筒1的底部，湿度传感器设置在衣物投放口所在平面水平对称轴的边缘下部能够较好的检测衣物的湿度值。
当然干衣机中也可以仅设置一对金属电极，这一对金属电极能够同时实现检测衣物的湿度值和衣物与该金属电极碰撞接触的次数，即通过一对金属电极同时完成湿度传感器和检测装置的任务。如果在干衣机中仅设置一对金属电极，当这对金属电极设置在衣物投放口所在平面水平对称轴的边缘下部时，该金属电极对衣物湿度检测(执行湿度传感器的功能)的比较准确，但对衣物的容量检测的不够准确。如果这对金属电极放置在衣物投放口所在平面水平对称轴的边缘的上部，该金属电极对衣物的容量(执行检测装置的功能)检测的准确度提高了，但对衣物的湿度检测的准确性就降低了。
实施例二
本实施例提出了一种干衣机控制方法，干衣筒以初始转速运转后，检测装置检测该检测装置周围环境中的阻抗值。控制器在预定时间内每间隔一预设时 间段获取检测装置检测得到的阻抗值。控制器将预定时间内检测得到的每一个阻抗值分别与阻抗阈值进行比较，并根据超过阻抗阈值的阻抗值的数量判断干衣筒中的衣物量，控制器根据干衣筒中的衣物量调整干衣筒的转速。作为可选的实施方式，控制器将干衣筒中的衣物量划分为至少三个等级，每个等级分别对应一个转速。
作为可选的实施方式，本实施例中控制器将干衣筒中的衣物量划分为三个等级，分别为小容量等级、中容量等级和大容量等级。本实施例中的阻抗阈值可以是经过多次试验获的一个经验值，也可以认为预先设定的满足客户需求的设定值。实际操作过程中，该阻抗阈值预存在控制器中。当控制器判定干衣筒1中的衣物量为小容量时，将干衣筒1的转速调节至低转速；当控制器判定干衣筒1中的衣物量为中容量时，将干衣筒1的转速调节至中转速；当控制器判定干衣筒1中的衣物量为大容量时，将干衣筒1的转速调节至高转速。其中，可选地，低转速为40-45rpm；中转速为50-55rpm；高转速为60-65rpm；干衣筒的初始转速为40rpm。
本实施例中使用金属电极作为检测装置的检测原理为：在干衣筒转动过程中，衣物和空气都可与检测装置的金属电极接触，可选地，检测装置由两条金属条电极组成。检测装置通过两条金属条电极组成检测回路，即可分别检测出衣物或者空气与电极之间的阻抗值。
控制器在预定时间内每间隔一预设时间段获取检测装置的阻抗值，可选地，该预设时间段为0.4秒，预定时间为3分钟。控制器可以主动获取阻抗值，即控制器每间隔0.4秒向检测装置发送获取阻抗值指令，检测装置接收到该指令后将获取到的阻抗值传输给控制器。
同样材质同样湿度的衣物，当干衣筒中的衣物量多时，衣物与干衣筒内壁接触的面积相对较大，与作为检测装置的金属条电极接触的频率较高，即金属条电极与衣物接触的次数多，与空气接触的次数少，因此，预定时间内检测装置测得的金属电极与衣物接触产生的阻抗值的次数较多，则控制器判定该预定时间内的多个阻抗值中超过阻抗阈值的阻抗值的数量较多。当衣物量少时，衣物与干衣筒内壁接触的面积相对较小，与作为检测装置的金属条电极接触的频 率较低，即金属条电极与衣物接触的次数少，与空气接触的次数少，因此，预定时间内检测装置测得的金属电极与衣物接触产生的阻抗值的次数较少，则控制器判定该预定时间内的多个阻抗值中超过阻抗阈值的阻抗值的数量较少。同理，当衣物量适中时，预定时间内检测装置测得的金属电极与衣物接触产生的阻抗值的次数也适中，则控制器判定该预定时间内的多个阻抗值中超过阻抗阈值的阻抗值的数量适中。
上述提及的衣物量的多、少或者适中，可以是衣物量相对于干衣筒的容量而言，例如，干衣筒的衣物容量为8kg，当衣物量超过6kg时，则说明干衣筒中的衣物量多，当干衣筒中的衣物量小于3kg时，则说明干衣筒的衣物量少，当干衣筒中的衣物量约为4kg左右时，则说明干衣筒的衣物量适中。
此外，上述提及的检测装置测得的阻抗值超过阻抗阈值的数量多、少或者适中，可以是阻抗值的数量相对于预设数量而言，例如，预设数量为300个，检测装置在预定时间内(3分钟内)测得阻抗值450个(每间隔0.4秒测一次)，当控制器判定该预定时间内的450个阻抗值中超过阻抗阈值的数量为380个(大于预设数量300个)，则判定干衣筒的衣物量为大容量；当控制器判定450个阻抗值中超过阻抗阈值的数量为280个(小于预设数量300个)，则判定干衣筒的衣物量为小容量；当控制器判定450个阻抗值中超过阻抗阈值的数量为300个(等于预设数量300个)，则判定干衣筒的衣物量为中容量。
下面通过可选的操作过程对干衣机的控制方法进行详细的描述：干衣机开启后，干衣筒以初始转速40rpm进行旋转，当干衣筒中的衣物与金属电极以相应频率接触，检测装置实时持续检测周围环境中的阻抗值，控制器每间隔0.4s(预设时间段)获取检测装置检测的阻抗值。在启动干衣机运转后的3分钟(预定时间)时间内(此预设时间段和预定时间均可以根据实际负载状况进行调整)，控制器保持每间隔0.4s获取一次阻抗值，控制器将每一次获取到的阻抗值与阻抗阈值进行比较，并根据3分钟时间内超过阻抗阈值的阻抗值的数量判断干衣筒中的衣物量，控制器根据干衣筒中的衣物量调整干衣筒的转速。例如，检测装置在3分钟内测得的阻抗值数据为450个(其中包括检测装置与衣物接触次数和检测装置与空气接触次数)，超过阻抗阈值的阻抗值的数量与干衣筒衣物容 量的对应关系为：超过阻抗阈值的阻抗值数量为380个时，控制器定义干衣筒衣物容量为大容量，则控制器将干衣筒的转速调整为60-65rpm；超过阻抗阈值的阻抗值数量为280时，控制器定义干衣筒的衣物容量为中容量，则控制器将干衣筒的转速调整为40-45rpm；超过阻抗阈值的阻抗值数量为180个时，控制器定义干衣筒的衣物容量为小容量；超过阻抗阈值的阻抗值的数量为300个，控制器定义干衣筒的衣物容量为为中容量，则控制器将干衣筒的转速调整为50-55rpm。
本实施例中的控制方法在判定干衣筒中的容量为小容量时，选择干衣筒低转速工作的原因是，为了防止干衣筒转速过高，使得衣物贴于干衣筒的筒壁，从而造成衣物与烘干风接触不均匀，同时防止干衣筒转速过高造成衣物受圆周方向上的挤压，产生褶皱无法舒展的问题。当干衣筒中的衣物量为大容量时，选择干衣筒高转速工作的原因是，通过增大角速度来加大离心力，让衣物在大离心力的作用下在干衣筒内舒展，防止大面积的褶皱产生同时提高烘干均匀性。当干衣筒中的衣物容量为中等容量时，选择干衣筒中转速工作的原因是，干衣筒保持适中的角速度运转，可以使衣物受到适当离心力而在筒内舒张，可防止衣物因转速过高而贴于筒壁，又可以防止干衣筒转速过低，衣物得不到充分的离心力，无法舒展，使得衣物以团状方式在筒内运转而出现过多褶皱的问题。
使用本实施例中的控制方法，控制器能够根据干衣筒中衣物量的多少对干衣筒的转速进行调节，当干衣筒中的衣物较多时，干衣筒中的转速提高，当干衣筒中的衣物较少时，干衣筒的转速较低，以实现干衣效果好，经过干衣机烘干的衣物不易出现褶皱的问题。
