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)(dian)(dian)熱毯的(de)保養應(ying)(ying)注(zhu)意以(yi)下幾點：①不用(yong)電(dian)(dian)(dian)(dian)熱毯時禁(jin)止(zhi)折(zhe)疊，存(cun)放(fang)(fang)(fang)時應(ying)(ying)輕輕疊并放(fang)(fang)(fang)在(zai)(zai)其它物(wu)品的(de)上面，以(yi)防電(dian)(dian)(dian)(dian)熱毯中的(de)電(dian)(dian)(dian)(dian)阻(zu)絲被壓(ya)斷；②清洗(xi)電(dian)(dian)(dian)(dian)熱毯時，絕不可用(yong)洗(xi)衣機洗(xi)滌，應(ying)(ying)用(yong)清水及(ji)洗(xi)衣粉(fen)輕輕刷洗(xi)，不能用(yong)手(shou)搓，待晾干(gan)(gan)后才能通電(dian)(dian)(dian)(dian)使(shi)用(yong)；③晾曬時，不應(ying)(ying)放(fang)(fang)(fang)在(zai)(zai)陽光下曝(pu)曬，更不能進行烘(hong)干(gan)(gan)處理，應(ying)(ying)放(fang)(fang)(fang)在(zai)(zai)陰涼通風處，讓其自(zi)然(ran)晾干(gan)(gan)；④電(dian)(dian)(dian)(dian)熱毯最好不要放(fang)(fang)(fang)在(zai)(zai)沙發或席夢思(si)床上，而應(ying)(ying)放(fang)(fang)(fang)在(zai)(zai)硬板床上。

二、電熱毯的使用

電(dian)(dian)(dian)(dian)熱(re)(re)(re)毯(tan)(tan)(tan)使(shi)(shi)(shi)用(yong)(yong)(yong)時(shi)(shi)應(ying)注(zhu)意以下(xia)幾點：①電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)應(ying)與電(dian)(dian)(dian)(dian)熱(re)(re)(re)毯(tan)(tan)(tan)允許額定電(dian)(dian)(dian)(dian)壓(ya)(ya)相符；②若存放后(hou)或新電(dian)(dian)(dian)(dian)熱(re)(re)(re)毯(tan)(tan)(tan)第一次(ci)使(shi)(shi)(shi)用(yong)(yong)(yong)，應(ying)先將(jiang)電(dian)(dian)(dian)(dian)熱(re)(re)(re)毯(tan)(tan)(tan)輕疊幾層并通(tong)(tong)電(dian)(dian)(dian)(dian)10分鐘作(zuo)預熱(re)(re)(re)試驗，因為折疊通(tong)(tong)電(dian)(dian)(dian)(dian)加熱(re)(re)(re)較(jiao)快(kuai)。若會發熱(re)(re)(re)，說明電(dian)(dian)(dian)(dian)熱(re)(re)(re)毯(tan)(tan)(tan)正常；若不(bu)發熱(re)(re)(re)，應(ying)停止(zhi)(zhi)使(shi)(shi)(shi)用(yong)(yong)(yong)并要(yao)進行檢修；③電(dian)(dian)(dian)(dian)熱(re)(re)(re)毯(tan)(tan)(tan)使(shi)(shi)(shi)用(yong)(yong)(yong)時(shi)(shi)應(ying)平鋪在床單(dan)下(xia)，禁止(zhi)(zhi)折疊通(tong)(tong)電(dian)(dian)(dian)(dian)使(shi)(shi)(shi)用(yong)(yong)(yong)，以免過熱(re)(re)(re)發生(sheng)意外事故；④使(shi)(shi)(shi)用(yong)(yong)(yong)時(shi)(shi)不(bu)能將(jiang)枕頭放在電(dian)(dian)(dian)(dian)熱(re)(re)(re)毯(tan)(tan)(tan)上；⑤小(xiao)孩或生(sheng)活(huo)不(bu)能自理的(de)人禁止(zhi)(zhi)使(shi)(shi)(shi)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)熱(re)(re)(re)毯(tan)(tan)(tan)，更不(bu)能用(yong)(yong)(yong)不(bu)合格的(de)電(dian)(dian)(dian)(dian)熱(re)(re)(re)毯(tan)(tan)(tan)；⑥應(ying)按(an)先高溫擋(dang)(dang)后(hou)保溫擋(dang)(dang)使(shi)(shi)(shi)用(yong)(yong)(yong)。

三、電熱毯的維修

①電(dian)(dian)熱(re)毯通電(dian)(dian)后(hou)不發熱(re)：此故障(zhang)(zhang)是(shi)電(dian)(dian)熱(re)毯的常見故障(zhang)(zhang)，應查(cha)電(dian)(dian)源線是(shi)否良好(hao)；電(dian)(dian)源插頭是(shi)否與電(dian)(dian)源接觸良好(hao)；電(dian)(dian)源開關(guan)是(shi)否良好(hao)；發熱(re)元(yuan)(yuan)件(jian)是(shi)否損壞。用萬用表查(cha)電(dian)(dian)源開關(guan)中(zhong)連接發熱(re)元(yuan)(yuan)件(jian)的端點(dian)，若阻值為∞，則為發熱(re)元(yuan)(yuan)件(jian)折斷，應更(geng)換(huan)發熱(re)元(yuan)(yuan)件(jian)。

②二極管(guan)調(diao)溫(wen)(wen)電熱毯調(diao)溫(wen)(wen)失靈(ling)：此故障(zhang)若(ruo)表現(xian)在(zai)低溫(wen)(wen)擋溫(wen)(wen)度仍很高，則(ze)說明調(diao)溫(wen)(wen)二極管(guan)擊穿；若(ruo)表現(xian)為只有高溫(wen)(wen)擋沒(mei)有低溫(wen)(wen)擋，則(ze)說明調(diao)溫(wen)(wen)二極管(guan)斷路，此二種(zhong)情況只要更換(huan)同規格的(de)二極管(guan)故障(zhang)即可排(pai)除。

③電(dian)容降(jiang)壓調(diao)溫(wen)電(dian)熱毯調(diao)溫(wen)失靈：此(ci)故(gu)障(zhang)若表現(xian)為高、低擋溫(wen)度均(jun)相同，則說明(ming)電(dian)容短(duan)路；若表現(xian)為只有置在(zai)高溫(wen)擋才有溫(wen)度，則說明(ming)電(dian)容斷路，此(ci)二種情況(kuang)需更換同規格的電(dian)容即可。

④電(dian)熱毯(tan)指示燈不(bu)亮但能(neng)正(zheng)常發(fa)(fa)熱：故(gu)障(zhang)原因可能(neng)是(shi)發(fa)(fa)光二極管或(huo)氖泡損壞，更(geng)換之(zhi)；發(fa)(fa)光二極管或(huo)氖泡的降(jiang)壓電(dian)阻損壞，更(geng)換同規格電(dian)阻即(ji)可（注(zhu)：串聯或(huo)并聯型(xing)的電(dian)阻阻值相(xiang)差特(te)別大(da)，更(geng)換時應注(zhu)意）；有關接(jie)線(xian)有虛焊(han)或(huo)脫滿，重(zhong)新焊(han)好即(ji)可。

電熱毯安全使用法

①電(dian)(dian)熱毯(tan)使(shi)用時要平(ping)鋪(pu)在墊(dian)胎上(shang)，毯(tan)面上(shang)加一(yi)條床單，以免弄臟電(dian)(dian)熱毯(tan)。切(qie)不(bu)可(ke)在床單和電(dian)(dian)熱毯(tan)之間再鋪(pu)墊(dian)棉胎或其它織物(wu)。開關要放在隨手可(ke)拿到的位置。

②臨睡前先(xian)開(kai)高溫檔，短時間內(nei)讓(rang)其預熱(re)升溫到所需溫度(du)。上床后，再調(diao)節到低溫檔保(bao)溫或關閉開(kai)關。

③電(dian)熱毯的溫度控(kong)制(zhi)在３８°Ｃ左右，最高(gao)不(bu)能超過 ４０°Ｃ。

④電(dian)(dian)熱(re)毯上(shang)不能放置尖銳的(de)金屬物(wu)件和既重又(you)硬的(de)物(wu)品(pin)，小(xiao)孩不宜在(zai)電(dian)(dian)熱(re)毯上(shang)蹦跳玩耍，以免損壞電(dian)(dian)熱(re)絲，引(yin)起(qi)觸電(dian)(dian)事故。

⑤經常(chang)檢查電熱(re)毯(tan)有(you)否(fou)集堆打褶現象，避(bi)免局部(bu)過(guo)熱(re)。為了(le)鋪平(ping)電熱(re)毯(tan)，四(si)只(zhi)角可各縫上布(bu)(bu)帶，把毯(tan)子拉平(ping)，再將布(bu)(bu)條(tiao)固定在床腿(tui)上。

⑥電(dian)熱毯(tan)不要(yao)與熱水(shui)袋、湯婆子(zi)一起(qi)使用(yong)。電(dian)熱毯(tan)局部過熱，是出現故障(zhang)的預兆，應(ying)馬上停用(yong)，并(bing)檢查修理。

電熱毯保養法

①卷(juan)(juan)毯：電(dian)熱毯不(bu)用(yong)時，應卷(juan)(juan)成圓筒狀，不(bu)要(yao)讓(rang)電(dian)熱毯有死彎，以(yi)免降低(di)電(dian)熱絲(si)的絕緣性能，上(shang)面忌(ji)放(fang)重物。

②去濕：電(dian)(dian)(dian)熱(re)毯收藏前，先平(ping)整地鋪開(kai)，插上電(dian)(dian)(dian)源，通電(dian)(dian)(dian)２０～３０分鐘后，讓它自然涼(liang)透(tou)，為電(dian)(dian)(dian)熱(re)絲和(he)電(dian)(dian)(dian)器元(yuan)件(jian)除潮。

③裝袋(dai)：去(qu)濕后拍去(qu)灰塵(chen)，將電源線和開(kai)關放在(zai)里面，然后卷成筒(tong)狀，裝入塑料袋(dai)內存放。

④透風(feng)：長(chang)久不用的電熱(re)毯(tan)要經常透風(feng)，將電熱(re)毯(tan)鋪平(ping)，再(zai)通電半小時，這樣(yang)既(ji)除潮又殺(sha)蟲，能使電熱(re)毯(tan)的壽命延長(chang)。
