一、為什么干手器能自動開關
自動(dong)開(kai)(kai)關(guan)是(shi)(shi)(shi)指人(ren)體(ti)紅外智能(neng)感應(ying)(ying)開(kai)(kai)關(guan),是(shi)(shi)(shi)一種當(dang)(dang)有人(ren)從(cong)紅外感應(ying)(ying)探測區域經(jing)過而自動(dong)啟動(dong)的(de)開(kai)(kai)關(guan)。那么干(gan)手(shou)(shou)器(qi)原理是(shi)(shi)(shi)什(shen)么呢?干(gan)手(shou)(shou)器(qi)能(neng)自動(dong)開(kai)(kai)關(guan)是(shi)(shi)(shi)因(yin)為在(zai)干(gan)手(shou)(shou)器(qi)內(nei)部(bu)(bu),安(an)裝了變容(rong)(rong)式(shi)自動(dong)感應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)路(lu),由它(ta)控制(zhi)著一個電(dian)(dian)(dian)(dian)(dian)橋平(ping)衡電(dian)(dian)(dian)(dian)(dian)路(lu)。電(dian)(dian)(dian)(dian)(dian)橋平(ping)衡電(dian)(dian)(dian)(dian)(dian)路(lu)由四(si)部(bu)(bu)分組成,稱為四(si)個橋臂(bei)。變容(rong)(rong)式(shi)自動(dong)感應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)路(lu)組成了其中(zhong)(zhong)的(de)一個橋臂(bei)。它(ta)的(de)感應(ying)(ying)部(bu)(bu)分,安(an)裝在(zai)干(gan)手(shou)(shou)器(qi)的(de)出(chu)風(feng)(feng)口(kou)處。當(dang)(dang)濕手(shou)(shou)在(zai)風(feng)(feng)口(kou)下出(chu)現時,因(yin)為人(ren)體(ti)是(shi)(shi)(shi)導體(ti),也能(neng)形成電(dian)(dian)(dian)(dian)(dian)容(rong)(rong),于是(shi)(shi)(shi),使(shi)(shi)感應(ying)(ying)部(bu)(bu)分的(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)量發生變化,立(li)即使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)橋電(dian)(dian)(dian)(dian)(dian)路(lu)中(zhong)(zhong)的(de)四(si)個橋臂(bei)的(de)量值,從(cong)平(ping)衡轉向不平(ping)衡。原來在(zai)平(ping)衡狀態下,橋臂(bei)中(zhong)(zhong)能(neng)互相(xiang)抵消的(de)電(dian)(dian)(dian)(dian)(dian)流(liu),不再抵消,出(chu)現了一股新的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)。它(ta)能(neng)使(shi)(shi)吸(xi)鐵(tie)繼電(dian)(dian)(dian)(dian)(dian)器(qi)動(dong)作,接通風(feng)(feng)扇和電(dian)(dian)(dian)(dian)(dian)熱器(qi)上的(de)電(dian)(dian)(dian)(dian)(dian)源,就會(hui)有風(feng)(feng)吹出(chu)來。
二、干手器安裝高度
干(gan)手(shou)(shou)器的安(an)裝高(gao)度(du)一(yi)般(ban)是在(zai)1.2m左右(you),離洗(xi)手(shou)(shou)臺30-40cm遠。如(ru)(ru)果安(an)裝在(zai)家(jia)中就要考慮使(shi)用(yong)人群,一(yi)般(ban)家(jia)用(yong)型的掛式感(gan)受求可以(yi)根據家(jia)人的平均身高(gao)來(lai)安(an)裝,如(ru)(ru)果有(you)小(xiao)孩可以(yi)選擇安(an)裝落地(di)式向上的干(gan)手(shou)(shou)器。
三、干手器有輻射嗎
一般通電的(de)東西都會有電離(li)輻(fu)射(she)的(de),只是(shi)輻(fu)射(she)大(da)小的(de)問題,干(gan)手器(qi)也是(shi)有輻(fu)射(she)的(de),不(bu)過不(bu)用擔心(xin),畢竟(jing)它的(de)體(ti)量并不(bu)大(da),并且你只是(shi)使(shi)用不(bu)到半分鐘,基本不(bu)會被輻(fu)射(she)所影響。
四、如何挑選干手器
挑選干手器主要根據自己的需要和環境等情況來決定是選以風為主熱量為輔的風量型的干手器,還是以熱量為主的熱風型干手器。此外,還需要考慮到干手器的外殼材質、重量、顏色、啟動原理、安裝方式、工作噪音、運行功率、干手時風溫等參數。購買的干手器品牌要有質量保障,以用起來舒適為宜(yi)。
