Abstract
一种家用电取暖的无场电热线,连接接地线的屏蔽层覆盖在普通电热线表面制成不产生变化电磁场的电热线。
Description
本实用新型属家用电取暖类物品。
一般电热毯使用的普通电热线通交流电时，周围会产生变化的电场和磁场，这种电磁场容易使人产生头晕、乏力、白天嗜睡等症状，并对孕妇体内的胎儿健康成长造成不良影响。
本实用新型的目的是提供一种不产生变化电磁场的电热线，用它制成的电热毯，消除变化电磁场对人体的影响，保护人体健康。
下面利用示图介绍本实用新型的特点。
如图是一种无场电热线的示图，它由屏蔽层(1)、普通电热线(2)和接地线(3)组成。屏蔽层(1)是屏蔽变化电磁场的层体，覆盖在普通电热线(2)上，用金属薄层、金属镀膜和金属丝网制成，例如铝箔和铜网；普通电热线(2)是一般电热毯上用来加热的带有绝缘层的电热线；接地线(3)是连接屏蔽层(1)和大地的导线。
本实用新型的目的是这样实现的：将连接接地线(3)的屏蔽层(1)覆盖在有绝缘层的普通电热线(2)表面制成无场电热线。
本实用新型的要点在于使用时将无场热线按需要附在毯子上制成无场电热毯，接地线(3)接地后给电热毯通电加热取暖，电热毯不产生变化的电磁场，有利于人体健康。
