一、為什么干手器能自動開關
自(zi)動開關(guan)是(shi)(shi)(shi)指(zhi)人(ren)體(ti)紅外(wai)智能感(gan)應(ying)(ying)開關(guan),是(shi)(shi)(shi)一(yi)種當有人(ren)從(cong)紅外(wai)感(gan)應(ying)(ying)探(tan)測區域經(jing)過而自(zi)動啟動的(de)(de)(de)開關(guan)。那么干(gan)(gan)手器(qi)原理是(shi)(shi)(shi)什么呢?干(gan)(gan)手器(qi)能自(zi)動開關(guan)是(shi)(shi)(shi)因(yin)為在(zai)干(gan)(gan)手器(qi)內部,安裝(zhuang)了(le)變(bian)容(rong)式自(zi)動感(gan)應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)路,由它控制著一(yi)個(ge)電(dian)(dian)(dian)(dian)(dian)橋(qiao)平(ping)衡(heng)(heng)電(dian)(dian)(dian)(dian)(dian)路。電(dian)(dian)(dian)(dian)(dian)橋(qiao)平(ping)衡(heng)(heng)電(dian)(dian)(dian)(dian)(dian)路由四部分組(zu)成,稱為四個(ge)橋(qiao)臂(bei)。變(bian)容(rong)式自(zi)動感(gan)應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)路組(zu)成了(le)其(qi)中的(de)(de)(de)一(yi)個(ge)橋(qiao)臂(bei)。它的(de)(de)(de)感(gan)應(ying)(ying)部分,安裝(zhuang)在(zai)干(gan)(gan)手器(qi)的(de)(de)(de)出(chu)風(feng)口處。當濕手在(zai)風(feng)口下出(chu)現時,因(yin)為人(ren)體(ti)是(shi)(shi)(shi)導體(ti),也(ye)能形成電(dian)(dian)(dian)(dian)(dian)容(rong),于是(shi)(shi)(shi),使(shi)感(gan)應(ying)(ying)部分的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)量發生變(bian)化,立即使(shi)電(dian)(dian)(dian)(dian)(dian)橋(qiao)電(dian)(dian)(dian)(dian)(dian)路中的(de)(de)(de)四個(ge)橋(qiao)臂(bei)的(de)(de)(de)量值,從(cong)平(ping)衡(heng)(heng)轉向不(bu)平(ping)衡(heng)(heng)。原來在(zai)平(ping)衡(heng)(heng)狀態下,橋(qiao)臂(bei)中能互相(xiang)抵消的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流,不(bu)再(zai)抵消,出(chu)現了(le)一(yi)股(gu)新的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流。它能使(shi)吸(xi)鐵(tie)繼電(dian)(dian)(dian)(dian)(dian)器(qi)動作,接通風(feng)扇和(he)電(dian)(dian)(dian)(dian)(dian)熱器(qi)上(shang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源,就會有風(feng)吹出(chu)來。
二、干手器安裝高度
干手器的安裝高(gao)度一般是在(zai)1.2m左(zuo)右,離洗手臺30-40cm遠(yuan)。如果安裝在(zai)家(jia)(jia)中(zhong)就要考慮使(shi)用人群(qun),一般家(jia)(jia)用型的掛式(shi)感(gan)受(shou)求可以根據家(jia)(jia)人的平均身高(gao)來安裝,如果有小孩可以選擇安裝落地(di)式(shi)向上的干手器。
三、干手器有輻射嗎
一般通(tong)電的(de)(de)東西都會有電離輻射(she)的(de)(de),只(zhi)是(shi)輻射(she)大小的(de)(de)問題,干手器(qi)也是(shi)有輻射(she)的(de)(de),不(bu)(bu)過(guo)不(bu)(bu)用擔心,畢竟它(ta)的(de)(de)體量(liang)并不(bu)(bu)大,并且(qie)你只(zhi)是(shi)使用不(bu)(bu)到半分鐘(zhong),基本不(bu)(bu)會被輻射(she)所影響(xiang)。
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(you)質(zhi)量保障,以用起來舒適為宜。
