Description

一种加热循环泵及洗衣机 技术领域
本发明属于衣物处理设备领域，具体地说，涉及一种带循环喷淋功能的洗衣机，尤其涉及一种应用于洗衣机的、具有加热功能的、用于驱动洗涤水在外桶外循环流动的加热循环泵。
背景技术
目前在家电领域，加热泵的应用普遍都是加热件不与水直接接触，这样可以有效的避免一些异物粘黏在加热管上，但是此种加热效率很低，大概在70％左右，就造成了能源浪费、加热时间过长的问题。
尤其是，将上述加热泵应用于洗衣机、对洗涤水进行加热时，由于洗衣机中的洗涤水总量较多，采用非接触式加热泵进行加热时耗时更长，拖慢了洗涤节拍、影响了用户使用体验。
但是，若直接将加热件设置于加热泵的腔室中、与水直接相接触加热，又会存在流经的洗衣机洗涤水中的线屑等异物与加热件直接相接触，使线屑等异物缠绕堆积于加热件处，就会导致影响加热效率、产生异味等问题，甚至严重时会导致加热件损坏情况的发生。
因此，如何设置一种适用于洗衣机的加热泵，使得泵上集成的加热件既能与水直接相接触进行加热、又防止洗涤水中的线屑等异物与加热件相接触，就成了研发热点。
有鉴于此，特提出本发明。
