在烘干衣物的过程中,在风机5的作用下,气流沿着内筒3、冷凝风道4A和加热风道4B循环流动,湿热空气在流经冷凝风道4A的过程中,其携带的水分被冷凝,从而变成干燥空气,干燥空气在流经加热风道4B的过程中,被设置在加热风道4B内的加热器81加热,从而变成热空气,热空气吹入内筒3中,对位于内筒3中的衣物进行烘干。
进风管路6的另一端与冷凝风道4A连通,出风管路7的另一端与加热风道4B连通,在衣物烘干结束之后,风机5继续运行,但设置在加热风道4B内的加热器81停止运行,在风机5的作用下,箱体1外部的冷空气沿进风管路6进入冷凝风道4A,与冷凝风道4A内的高温气体混合后进入加热风道4B,混合气体在流经加热风道4B与出风管路7的连接处时,一部分气体继续沿着加热风道4B流入内筒3中,还有一部分气体沿着进风管路6排出至箱体1的外部,从而在箱体1的内部

在烘干衣物的过程中,在风机5的作用下,气流沿着内筒3、冷凝风道4A和加热风道4B循环流动,湿热空气在流经冷凝风道4A的过程中,其携带的水分被冷凝,从而变成干燥空气,干燥空气在流经加热风道4B的过程中,被设置在加热风道4B内的加热器81加热,从而变成热空气,热空气吹入内筒3中,对位于内筒3中的衣物进行烘干。
进风管路6的另一端与冷凝风道4A连通,出风管路7的另一端借助第一连通孔41与加热风道4B连通,在衣物烘干结束之后,风机5继续运行,但设置在加热风道4B内的加热器81停止运行,在风机5的作用下,箱体1外部的冷空气沿进风管路6进入冷凝风道4A,与冷凝风道4A内的高温气体混合后进入加热风道4B,混合气体在流经加热风道4B与出风管路7的连接处时,一部分气体继续沿着加热风道4B流入内筒3中,还有一部分气体沿着进风管路6排出至箱体1的外部,从而在箱体1的内部形成内、外两个循环,能够尽快将箱体1内的温度降下来。
需要说明的是,设置进风管路6和出风管路7将烘干风道4与箱体1的外部连通,除了能够实现上述描述的作用外,还具有其他的作用。
例如,如果用户没有选择烘干程序,通过设置进风管路6和出风管路7还能够实现除湿、干衣和除味的作用,减少筒内细菌滋生。
具体而言,用户洗完衣物后,筒内潮湿,此时开启风机5,加强筒内与外界环境的气流交换,烘干风道4与进风管路6、出风管路7形成了内、外两个循环,这两个循环的作用各不相同,内循环风量大、风速高,能够快速带走衣物表面的水分,外循环的作用主要是将湿气排出,避免筒内空气达到饱和状态,从而可以不断地带走衣物表面的水分,干燥筒内环境,避免异味、霉菌等产生;此外,如果用户洗完衣物后未及时取出,尤其是晚上,此时开启风机5,并配合内筒3旋转,能够避免衣物褶皱、降低衣物含水率,少量衣物可以实现明早即穿的效果;因此新风功能够在低噪音、低功耗的情况下运行。
