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)熱(re)(re)毯(tan)的保(bao)養應(ying)注意以(yi)下幾點：①不(bu)用電(dian)熱(re)(re)毯(tan)時禁止折疊，存放(fang)時應(ying)輕輕疊并放(fang)在其(qi)它物品(pin)的上面，以(yi)防電(dian)熱(re)(re)毯(tan)中的電(dian)阻(zu)絲被壓(ya)斷；②清(qing)洗(xi)電(dian)熱(re)(re)毯(tan)時，絕不(bu)可(ke)用洗(xi)衣機(ji)洗(xi)滌，應(ying)用清(qing)水及洗(xi)衣粉輕輕刷(shua)洗(xi)，不(bu)能用手搓，待晾干后才(cai)能通電(dian)使(shi)用；③晾曬(shai)時，不(bu)應(ying)放(fang)在陽(yang)光下曝曬(shai)，更不(bu)能進(jin)行烘(hong)干處理，應(ying)放(fang)在陰涼通風(feng)處，讓其(qi)自(zi)然晾干；④電(dian)熱(re)(re)毯(tan)最好不(bu)要(yao)放(fang)在沙(sha)發或席夢思(si)床(chuang)上，而(er)應(ying)放(fang)在硬(ying)板(ban)床(chuang)上。

二、電熱毯的使用

電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)毯(tan)使(shi)用時(shi)應(ying)(ying)注意(yi)以(yi)下(xia)幾點：①電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)壓(ya)應(ying)(ying)與電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)毯(tan)允許額定電(dian)(dian)(dian)(dian)(dian)壓(ya)相符(fu)；②若存放后或(huo)新電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)毯(tan)第一(yi)次使(shi)用，應(ying)(ying)先將電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)毯(tan)輕疊(die)幾層并(bing)通電(dian)(dian)(dian)(dian)(dian)10分鐘作預熱(re)(re)(re)(re)試(shi)驗，因為折疊(die)通電(dian)(dian)(dian)(dian)(dian)加熱(re)(re)(re)(re)較快。若會發(fa)熱(re)(re)(re)(re)，說明電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)毯(tan)正常；若不(bu)(bu)發(fa)熱(re)(re)(re)(re)，應(ying)(ying)停止使(shi)用并(bing)要進行檢修；③電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)毯(tan)使(shi)用時(shi)應(ying)(ying)平(ping)鋪在床單下(xia)，禁(jin)(jin)止折疊(die)通電(dian)(dian)(dian)(dian)(dian)使(shi)用，以(yi)免過熱(re)(re)(re)(re)發(fa)生(sheng)意(yi)外事(shi)故；④使(shi)用時(shi)不(bu)(bu)能(neng)(neng)將枕(zhen)頭放在電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)毯(tan)上；⑤小孩或(huo)生(sheng)活不(bu)(bu)能(neng)(neng)自理(li)的(de)(de)人禁(jin)(jin)止使(shi)用電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)毯(tan)，更不(bu)(bu)能(neng)(neng)用不(bu)(bu)合格的(de)(de)電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)毯(tan)；⑥應(ying)(ying)按先高(gao)溫(wen)擋后保溫(wen)擋使(shi)用。

三、電熱毯的維修

①電(dian)(dian)熱(re)毯通電(dian)(dian)后不(bu)發(fa)(fa)熱(re)：此故障是電(dian)(dian)熱(re)毯的常見故障，應(ying)查(cha)電(dian)(dian)源(yuan)(yuan)線(xian)是否良(liang)好；電(dian)(dian)源(yuan)(yuan)插(cha)頭是否與電(dian)(dian)源(yuan)(yuan)接(jie)觸良(liang)好；電(dian)(dian)源(yuan)(yuan)開關是否良(liang)好；發(fa)(fa)熱(re)元(yuan)件(jian)(jian)是否損壞。用(yong)萬用(yong)表查(cha)電(dian)(dian)源(yuan)(yuan)開關中(zhong)連接(jie)發(fa)(fa)熱(re)元(yuan)件(jian)(jian)的端點，若阻值為∞，則(ze)為發(fa)(fa)熱(re)元(yuan)件(jian)(jian)折斷，應(ying)更換發(fa)(fa)熱(re)元(yuan)件(jian)(jian)。

②二(er)極管調溫(wen)(wen)電熱毯調溫(wen)(wen)失(shi)靈：此故障(zhang)若表(biao)現在低溫(wen)(wen)擋溫(wen)(wen)度仍很(hen)高，則說(shuo)明調溫(wen)(wen)二(er)極管擊穿；若表(biao)現為(wei)只有高溫(wen)(wen)擋沒(mei)有低溫(wen)(wen)擋，則說(shuo)明調溫(wen)(wen)二(er)極管斷路(lu)，此二(er)種情況(kuang)只要更換同規格的二(er)極管故障(zhang)即可(ke)排除。

③電(dian)容(rong)降(jiang)壓(ya)調(diao)溫(wen)(wen)電(dian)熱(re)毯(tan)調(diao)溫(wen)(wen)失靈：此故障若表現為(wei)(wei)高、低擋(dang)溫(wen)(wen)度均(jun)相同，則說(shuo)明(ming)電(dian)容(rong)短路(lu)(lu)；若表現為(wei)(wei)只(zhi)有置在高溫(wen)(wen)擋(dang)才有溫(wen)(wen)度，則說(shuo)明(ming)電(dian)容(rong)斷路(lu)(lu)，此二種情況(kuang)需更換(huan)同規格的電(dian)容(rong)即可。

④電熱(re)毯指示燈不亮但(dan)能正(zheng)常發(fa)熱(re)：故障原因可能是(shi)發(fa)光(guang)二極管或氖泡(pao)損壞，更(geng)(geng)換之；發(fa)光(guang)二極管或氖泡(pao)的降壓電阻損壞，更(geng)(geng)換同(tong)規格(ge)電阻即可（注(zhu)：串(chuan)聯(lian)或并聯(lian)型的電阻阻值相差特(te)別大，更(geng)(geng)換時應(ying)注(zhu)意）；有關接線有虛焊或脫滿(man)，重(zhong)新(xin)焊好即可。

電熱毯安全使用法

①電熱(re)(re)毯(tan)使用(yong)時要(yao)平(ping)鋪(pu)在(zai)墊胎(tai)(tai)上，毯(tan)面上加一條床單(dan)，以免弄臟電熱(re)(re)毯(tan)。切不可(ke)在(zai)床單(dan)和電熱(re)(re)毯(tan)之間再鋪(pu)墊棉胎(tai)(tai)或其(qi)它織物。開關要(yao)放在(zai)隨手可(ke)拿(na)到的位置。

②臨(lin)睡前先開高溫(wen)檔，短(duan)時(shi)間內(nei)讓其預熱升溫(wen)到(dao)所(suo)需溫(wen)度(du)。上(shang)床后，再調節(jie)到(dao)低溫(wen)檔保溫(wen)或關閉(bi)開關。

③電(dian)熱毯的(de)溫度控制在３８°Ｃ左(zuo)右，最高(gao)不能(neng)超過 ４０°Ｃ。

④電熱毯上不能(neng)放(fang)置尖銳的(de)金(jin)屬物件和既重又(you)硬(ying)的(de)物品，小孩不宜(yi)在電熱毯上蹦跳(tiao)玩耍(shua)，以免(mian)損壞(huai)電熱絲，引起觸電事故。

⑤經(jing)常檢查電熱毯(tan)有(you)否集堆打(da)褶(zhe)現(xian)象，避免局部過(guo)熱。為了鋪平(ping)(ping)電熱毯(tan)，四只(zhi)角可各縫上布帶，把毯(tan)子拉平(ping)(ping)，再將布條固定在(zai)床腿上。

⑥電熱(re)(re)毯(tan)不(bu)要與熱(re)(re)水袋(dai)、湯婆子一起使用。電熱(re)(re)毯(tan)局部過熱(re)(re)，是出現故(gu)障(zhang)的預(yu)兆，應馬上停用，并(bing)檢查修理。

電熱毯保養法

①卷毯：電(dian)熱毯不(bu)用時，應卷成圓筒狀，不(bu)要(yao)讓電(dian)熱毯有死彎，以免降低電(dian)熱絲的絕緣(yuan)性能，上面忌放重(zhong)物(wu)。

②去濕：電(dian)熱毯收藏前，先平整地(di)鋪開(kai)，插上電(dian)源，通(tong)電(dian)２０～３０分鐘后，讓(rang)它自然涼透，為(wei)電(dian)熱絲和電(dian)器(qi)元件(jian)除潮。

③裝袋(dai)：去濕后拍去灰塵，將(jiang)電源線和(he)開(kai)關放在里面，然后卷成筒狀，裝入(ru)塑料袋(dai)內存(cun)放。

④透風：長久不(bu)用(yong)的(de)電(dian)熱毯(tan)要經常透風，將電(dian)熱毯(tan)鋪平，再通電(dian)半小(xiao)時(shi)，這(zhe)樣既除(chu)潮又殺蟲，能使電(dian)熱毯(tan)的(de)壽(shou)命(ming)延長。
