Abstract

本实用新型是一种电热毯,其特征是由整流装置或采用往复式双股电阻线铺设,它改变了以往电热毯的交流电磁场对人体的影响。有益健康。

Description

电热毯
本实用新型是一种电热毯
目前的电热毯在接通交流电源后,其电阻丝周围可产生交替变化的磁场。
电流强度极大的交流电导线周围,其交替变化的磁场会较大地影响人的健康。
电流强度较弱时,对人体健康影响虽然较小,但就电热毯讲有三个因素不可忽视:一是人离导线近,因为人是躺在电热毯上的;二是人与导线接触范围大,几乎整个人体是躺在这种交替变化磁场里;三是时间长,人睡觉时间大都在六个小时以上。这样,电热毯通交流电时,其产生的磁场对人体的影响就不可忽视了。
本实用新型的目的是为了削弱电热毯这种对健康的不利影响。
本实用新型的目的可以通过以下两种方式实现。
一是在电热毯上设有整流装置,把交流电变成直流电,如果变成稳恒直流电更好,如果不是稳恒直流电,虽然其导线周围磁场强度也是变化的,但磁场方向却是恒定的,不象交流电导线周围的磁砀方向一会向左一会向右的变化,所以对健康影响较小。二是采用往复式双股电阻线,铺设在电热毯上,这样双股电阻线的电流方向相反。所以两股电阻线所产生的磁场大部分抵销。
图1是采用往复式双股电阻线的电热毯的一个具体实施例。如图1所示:
本实用新型是由2和3组成的往复式双股电阻线、插头4、及毛毯1构成。
当4接入交流电源后,由于2和3的电流方向相反,所以2和3产生的磁场大部抵销,而对毛毯1的供热却不受影响。
当然,2和3都是带有绝缘皮的,2和3可以拧成一股绳状。
