一、為什么干手器能自動開關

自動(dong)開(kai)關是指人(ren)(ren)體紅(hong)外智能(neng)(neng)感應(ying)(ying)開(kai)關，是一種當有(you)人(ren)(ren)從(cong)(cong)紅(hong)外感應(ying)(ying)探(tan)測區域經(jing)過而(er)自動(dong)啟(qi)動(dong)的(de)(de)(de)開(kai)關。那么干手器(qi)原理(li)是什(shen)么呢？干手器(qi)能(neng)(neng)自動(dong)開(kai)關是因(yin)為(wei)在干手器(qi)內部(bu)，安(an)裝了(le)變容(rong)式自動(dong)感應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)路(lu)，由它控制(zhi)著一個電(dian)(dian)(dian)(dian)(dian)橋(qiao)平衡(heng)(heng)電(dian)(dian)(dian)(dian)(dian)路(lu)。電(dian)(dian)(dian)(dian)(dian)橋(qiao)平衡(heng)(heng)電(dian)(dian)(dian)(dian)(dian)路(lu)由四(si)部(bu)分組(zu)成(cheng)(cheng)，稱為(wei)四(si)個橋(qiao)臂(bei)。變容(rong)式自動(dong)感應(ying)(ying)電(dian)(dian)(dian)(dian)(dian)路(lu)組(zu)成(cheng)(cheng)了(le)其中的(de)(de)(de)一個橋(qiao)臂(bei)。它的(de)(de)(de)感應(ying)(ying)部(bu)分，安(an)裝在干手器(qi)的(de)(de)(de)出(chu)(chu)風(feng)口處。當濕手在風(feng)口下出(chu)(chu)現時(shi)，因(yin)為(wei)人(ren)(ren)體是導體，也能(neng)(neng)形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)容(rong)，于是，使(shi)感應(ying)(ying)部(bu)分的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)量發生變化(hua)，立即使(shi)電(dian)(dian)(dian)(dian)(dian)橋(qiao)電(dian)(dian)(dian)(dian)(dian)路(lu)中的(de)(de)(de)四(si)個橋(qiao)臂(bei)的(de)(de)(de)量值，從(cong)(cong)平衡(heng)(heng)轉向不平衡(heng)(heng)。原來在平衡(heng)(heng)狀態下，橋(qiao)臂(bei)中能(neng)(neng)互相抵(di)消的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)，不再抵(di)消，出(chu)(chu)現了(le)一股新(xin)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)。它能(neng)(neng)使(shi)吸鐵繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)動(dong)作，接通風(feng)扇和電(dian)(dian)(dian)(dian)(dian)熱器(qi)上的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)，就會有(you)風(feng)吹出(chu)(chu)來。

二、干手器安裝高度

干(gan)(gan)手(shou)(shou)器的安裝高度一(yi)般是在(zai)1.2m左右，離洗(xi)手(shou)(shou)臺(tai)30-40cm遠(yuan)。如果安裝在(zai)家中就要考慮使(shi)用人群(qun)，一(yi)般家用型的掛(gua)式感受求可以(yi)根據家人的平(ping)均身高來(lai)安裝，如果有小孩可以(yi)選擇安裝落地式向上的干(gan)(gan)手(shou)(shou)器。

三、干手器有輻射嗎

一(yi)般通電的(de)東西都會(hui)有電離輻射(she)的(de)，只(zhi)是(shi)(shi)輻射(she)大小的(de)問題(ti)，干手器也是(shi)(shi)有輻射(she)的(de)，不(bu)(bu)過不(bu)(bu)用(yong)擔心，畢竟它的(de)體量(liang)并不(bu)(bu)大，并且你只(zhi)是(shi)(shi)使(shi)用(yong)不(bu)(bu)到半分鐘，基本不(bu)(bu)會(hui)被(bei)輻射(she)所(suo)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(yao)有質(zhi)量保(bao)障，以(yi)用起(qi)來舒適為宜。
