電熱毯的維修保養事項 4大方法輕松排除電熱毯故障

一、電熱毯的保養

電(dian)(dian)熱(re)毯(tan)(tan)(tan)的(de)保養應(ying)注意(yi)以(yi)下(xia)(xia)幾點：①不(bu)用(yong)(yong)電(dian)(dian)熱(re)毯(tan)(tan)(tan)時禁止折(zhe)疊，存放(fang)(fang)時應(ying)輕(qing)輕(qing)疊并放(fang)(fang)在其(qi)(qi)它物(wu)品(pin)的(de)上面(mian)，以(yi)防(fang)電(dian)(dian)熱(re)毯(tan)(tan)(tan)中的(de)電(dian)(dian)阻絲被壓(ya)斷(duan)；②清洗(xi)(xi)電(dian)(dian)熱(re)毯(tan)(tan)(tan)時，絕不(bu)可用(yong)(yong)洗(xi)(xi)衣機(ji)洗(xi)(xi)滌(di)，應(ying)用(yong)(yong)清水及洗(xi)(xi)衣粉輕(qing)輕(qing)刷洗(xi)(xi)，不(bu)能(neng)用(yong)(yong)手搓，待晾(liang)干(gan)后才能(neng)通電(dian)(dian)使用(yong)(yong)；③晾(liang)曬時，不(bu)應(ying)放(fang)(fang)在陽光下(xia)(xia)曝曬，更不(bu)能(neng)進行烘干(gan)處理，應(ying)放(fang)(fang)在陰涼(liang)通風處，讓其(qi)(qi)自然晾(liang)干(gan)；④電(dian)(dian)熱(re)毯(tan)(tan)(tan)最好不(bu)要放(fang)(fang)在沙發(fa)或席夢思(si)床上，而應(ying)放(fang)(fang)在硬板床上。

二、電熱毯的使用

電(dian)(dian)(dian)熱(re)毯(tan)(tan)使用(yong)(yong)(yong)時(shi)應(ying)注意以(yi)下(xia)幾點：①電(dian)(dian)(dian)源電(dian)(dian)(dian)壓應(ying)與電(dian)(dian)(dian)熱(re)毯(tan)(tan)允許額定電(dian)(dian)(dian)壓相符；②若(ruo)存放后(hou)或新(xin)電(dian)(dian)(dian)熱(re)毯(tan)(tan)第(di)一次使用(yong)(yong)(yong)，應(ying)先(xian)將電(dian)(dian)(dian)熱(re)毯(tan)(tan)輕疊(die)(die)幾層并(bing)通電(dian)(dian)(dian)10分鐘作預(yu)熱(re)試驗，因為折疊(die)(die)通電(dian)(dian)(dian)加熱(re)較快。若(ruo)會發(fa)熱(re)，說明電(dian)(dian)(dian)熱(re)毯(tan)(tan)正常；若(ruo)不發(fa)熱(re)，應(ying)停止使用(yong)(yong)(yong)并(bing)要(yao)進行檢修；③電(dian)(dian)(dian)熱(re)毯(tan)(tan)使用(yong)(yong)(yong)時(shi)應(ying)平鋪在(zai)床單下(xia)，禁止折疊(die)(die)通電(dian)(dian)(dian)使用(yong)(yong)(yong)，以(yi)免過熱(re)發(fa)生意外事故；④使用(yong)(yong)(yong)時(shi)不能(neng)將枕頭放在(zai)電(dian)(dian)(dian)熱(re)毯(tan)(tan)上(shang)；⑤小孩(hai)或生活不能(neng)自(zi)理的人禁止使用(yong)(yong)(yong)電(dian)(dian)(dian)熱(re)毯(tan)(tan)，更不能(neng)用(yong)(yong)(yong)不合格的電(dian)(dian)(dian)熱(re)毯(tan)(tan)；⑥應(ying)按先(xian)高(gao)溫擋(dang)后(hou)保溫擋(dang)使用(yong)(yong)(yong)。

三、電熱毯的維修

①電(dian)(dian)熱(re)毯通電(dian)(dian)后不發熱(re)：此故障是電(dian)(dian)熱(re)毯的常見故障，應(ying)查電(dian)(dian)源線是否(fou)良好；電(dian)(dian)源插頭是否(fou)與電(dian)(dian)源接(jie)觸良好；電(dian)(dian)源開(kai)(kai)關(guan)是否(fou)良好；發熱(re)元(yuan)件(jian)是否(fou)損壞。用(yong)萬用(yong)表(biao)查電(dian)(dian)源開(kai)(kai)關(guan)中連接(jie)發熱(re)元(yuan)件(jian)的端點(dian)，若阻值為∞，則為發熱(re)元(yuan)件(jian)折斷，應(ying)更換發熱(re)元(yuan)件(jian)。

②二(er)極(ji)管(guan)調(diao)溫電熱毯調(diao)溫失靈：此故障若(ruo)表(biao)現(xian)在(zai)低溫擋溫度仍很高(gao)，則說明調(diao)溫二(er)極(ji)管(guan)擊穿；若(ruo)表(biao)現(xian)為只(zhi)有高(gao)溫擋沒有低溫擋，則說明調(diao)溫二(er)極(ji)管(guan)斷路，此二(er)種(zhong)情況只(zhi)要(yao)更換同規格的(de)二(er)極(ji)管(guan)故障即可排除。

③電(dian)容降(jiang)壓調溫(wen)電(dian)熱毯調溫(wen)失靈：此故障若(ruo)表現(xian)為高、低(di)擋溫(wen)度均(jun)相同(tong)，則說明(ming)電(dian)容短(duan)路(lu)；若(ruo)表現(xian)為只有置在高溫(wen)擋才有溫(wen)度，則說明(ming)電(dian)容斷路(lu)，此二種(zhong)情(qing)況需更換同(tong)規格的電(dian)容即可。

④電(dian)熱(re)毯指示(shi)燈(deng)不亮但能正常發熱(re)：故障原因(yin)可能是發光(guang)二極管或氖泡損壞，更換之；發光(guang)二極管或氖泡的降壓(ya)電(dian)阻(zu)損壞，更換同規格電(dian)阻(zu)即可（注(zhu)：串(chuan)聯或并聯型的電(dian)阻(zu)阻(zu)值相(xiang)差特別大，更換時應注(zhu)意）；有關接線(xian)有虛(xu)焊或脫滿，重新焊好(hao)即可。

電熱毯安全使用法

①電(dian)熱(re)毯(tan)(tan)使(shi)用時(shi)要平鋪在墊胎上(shang)，毯(tan)(tan)面上(shang)加(jia)一條床(chuang)單，以免(mian)弄臟電(dian)熱(re)毯(tan)(tan)。切不可在床(chuang)單和電(dian)熱(re)毯(tan)(tan)之間再鋪墊棉胎或其它織物。開關(guan)要放在隨手可拿到的(de)位置(zhi)。

②臨睡前先開(kai)高溫(wen)檔，短(duan)時間內讓(rang)其預熱(re)升溫(wen)到(dao)所需溫(wen)度(du)。上床后，再(zai)調節到(dao)低溫(wen)檔保溫(wen)或關(guan)(guan)閉(bi)開(kai)關(guan)(guan)。

③電(dian)熱毯的溫度(du)控制在３８°Ｃ左右(you)，最高(gao)不(bu)能超過 ４０°Ｃ。

④電(dian)熱毯上不能放置(zhi)尖(jian)銳的金屬(shu)物(wu)件和(he)既重又硬的物(wu)品，小孩(hai)不宜在(zai)電(dian)熱毯上蹦跳(tiao)玩(wan)耍，以免損壞(huai)電(dian)熱絲，引起(qi)觸電(dian)事故。

⑤經常(chang)檢查電熱(re)(re)毯有(you)否(fou)集堆打褶現象，避免局部(bu)過熱(re)(re)。為(wei)了鋪平(ping)電熱(re)(re)毯，四只角可(ke)各(ge)縫上布帶(dai)，把毯子拉(la)平(ping)，再將布條固(gu)定在床腿上。

⑥電(dian)熱毯不要與(yu)熱水袋、湯婆子一起使用(yong)。電(dian)熱毯局部過(guo)熱，是(shi)出(chu)現故障的預兆(zhao)，應馬上停用(yong)，并檢(jian)查修理。

電熱毯保養法

①卷毯：電(dian)熱毯不(bu)用(yong)時，應卷成圓(yuan)筒狀，不(bu)要讓(rang)電(dian)熱毯有死彎，以免降低電(dian)熱絲的絕緣性(xing)能，上(shang)面忌放重物。

②去(qu)濕：電熱毯收(shou)藏前，先(xian)平整地鋪開，插上電源，通電２０～３０分鐘(zhong)后，讓它(ta)自然涼透，為電熱絲和(he)電器元件除(chu)潮。

③裝袋(dai)：去(qu)濕后(hou)拍(pai)去(qu)灰塵，將電源線和開(kai)關(guan)放(fang)在里面，然后(hou)卷(juan)成筒狀(zhuang)，裝入塑料袋(dai)內存放(fang)。

④透風：長久(jiu)不用的電(dian)熱(re)毯(tan)要經常(chang)透風，將電(dian)熱(re)毯(tan)鋪平，再通電(dian)半小(xiao)時，這樣既(ji)除潮又(you)殺蟲，能使電(dian)熱(re)毯(tan)的壽(shou)命延長。
