摘 要:人体红外感应技术已成功运用到防盗报警、灯光控制、卫厨设备等方面,但在电暖器具方面的应用还是空白。为杜绝普通电暖器引发火灾事故和避免电能浪费,将人体感应、自动延时、断电自锁等技术和方法应用到电暖器上,设计制作了具有多重保护功能的电暖器。通过对PIR管安装位置、温度、取暖人数、延时时长等因素进行试验,结果表明,红外感应技术应用到电暖器上有明显的保安节电效果,具有实际推广应用的价值。

Abstract:Human infrared induction technology has not yet been used in electric heating appliances,although has been successfully applied to anti-theft alarm,lighting control,kitchen equipments,etc..In order to prevent fire disaster caused by general heaters and avoid wasting energy,a multi-protection heater is designed based on the techniques and methods of body induction,automatic delay,power self-locking etc.Tested on the factors including the placement of PIR tube,temperature,the number of heating people,delay duration The results show that the infrared induction technology used on the heater has obvious security and energy-saving effects and it is valuable for practical application.

Keywords:security energy-saving; heater; infrared induction; designed experiment

应用各种发热器件制作的电暖器已普及到城乡千家万户。不论是已安装了空调设备、还是使用其他取暖设备的场所,包括办公场所,个别地方甚至达到了人手一台的程度。说明了这类取暖设备结构简单,价格低廉、节电节能,使用方便,得到了人们的青睐与喜欢,在今后相当长的时期内,尤其是在南方,仍具有广阔的市场前景。但是,因使用电暖器不慎而造成的火灾时有发生,有些火灾给人们的生命财产造成了无法挽回的损害。根据调查分析,结合身边所发生过的案例,并参考各种媒体的报道可知,引起火灾的主要原因是人们因某种原因突然外出,或睡觉休息等忘记关断电源,时间长而引发了火灾[1,2]。人们不能绝对保证在所有用电的场所、所有的时刻不发生一点点疏忽大意,也不是说一二次的疏忽大意就必然会发生火灾事故,但一旦发生、一旦发生到某家底、某个人身上,则对于这个家庭将是灾难性的、将造成无法挽回的后果。……
