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)毯的保養應(ying)注意以下幾點：①不(bu)用(yong)電(dian)(dian)熱(re)毯時(shi)禁止折(zhe)疊，存放(fang)時(shi)應(ying)輕(qing)輕(qing)疊并放(fang)在(zai)其它物品的上(shang)面(mian)，以防電(dian)(dian)熱(re)毯中的電(dian)(dian)阻絲被壓斷；②清(qing)洗(xi)(xi)(xi)電(dian)(dian)熱(re)毯時(shi)，絕(jue)不(bu)可用(yong)洗(xi)(xi)(xi)衣機洗(xi)(xi)(xi)滌，應(ying)用(yong)清(qing)水及洗(xi)(xi)(xi)衣粉輕(qing)輕(qing)刷(shua)洗(xi)(xi)(xi)，不(bu)能(neng)用(yong)手(shou)搓，待晾干后才能(neng)通電(dian)(dian)使用(yong)；③晾曬時(shi)，不(bu)應(ying)放(fang)在(zai)陽光下曝曬，更不(bu)能(neng)進行烘干處(chu)理，應(ying)放(fang)在(zai)陰涼通風(feng)處(chu)，讓其自然晾干；④電(dian)(dian)熱(re)毯最好(hao)不(bu)要放(fang)在(zai)沙發或席夢(meng)思床上(shang)，而應(ying)放(fang)在(zai)硬板床上(shang)。

二、電熱毯的使用

電(dian)(dian)熱(re)(re)(re)(re)毯使(shi)(shi)用(yong)(yong)(yong)時(shi)應(ying)注意以下幾(ji)點：①電(dian)(dian)源電(dian)(dian)壓應(ying)與電(dian)(dian)熱(re)(re)(re)(re)毯允許額定電(dian)(dian)壓相符；②若(ruo)存(cun)放(fang)后或新(xin)電(dian)(dian)熱(re)(re)(re)(re)毯第一次使(shi)(shi)用(yong)(yong)(yong)，應(ying)先將電(dian)(dian)熱(re)(re)(re)(re)毯輕疊(die)(die)幾(ji)層(ceng)并通電(dian)(dian)10分鐘作預(yu)熱(re)(re)(re)(re)試驗(yan)，因為折疊(die)(die)通電(dian)(dian)加熱(re)(re)(re)(re)較快。若(ruo)會發熱(re)(re)(re)(re)，說明電(dian)(dian)熱(re)(re)(re)(re)毯正常；若(ruo)不(bu)發熱(re)(re)(re)(re)，應(ying)停止使(shi)(shi)用(yong)(yong)(yong)并要進行檢修；③電(dian)(dian)熱(re)(re)(re)(re)毯使(shi)(shi)用(yong)(yong)(yong)時(shi)應(ying)平鋪在床單下，禁止折疊(die)(die)通電(dian)(dian)使(shi)(shi)用(yong)(yong)(yong)，以免過熱(re)(re)(re)(re)發生(sheng)意外事(shi)故；④使(shi)(shi)用(yong)(yong)(yong)時(shi)不(bu)能(neng)將枕(zhen)頭放(fang)在電(dian)(dian)熱(re)(re)(re)(re)毯上(shang)；⑤小(xiao)孩或生(sheng)活不(bu)能(neng)自理的人禁止使(shi)(shi)用(yong)(yong)(yong)電(dian)(dian)熱(re)(re)(re)(re)毯，更不(bu)能(neng)用(yong)(yong)(yong)不(bu)合格的電(dian)(dian)熱(re)(re)(re)(re)毯；⑥應(ying)按先高溫(wen)擋后保溫(wen)擋使(shi)(shi)用(yong)(yong)(yong)。

三、電熱毯的維修

①電(dian)(dian)熱(re)毯(tan)通(tong)電(dian)(dian)后不發熱(re)：此故(gu)障是(shi)電(dian)(dian)熱(re)毯(tan)的(de)常見故(gu)障，應查(cha)電(dian)(dian)源(yuan)線是(shi)否良好；電(dian)(dian)源(yuan)插頭是(shi)否與電(dian)(dian)源(yuan)接(jie)觸良好；電(dian)(dian)源(yuan)開關是(shi)否良好；發熱(re)元(yuan)(yuan)件(jian)是(shi)否損壞。用(yong)萬用(yong)表(biao)查(cha)電(dian)(dian)源(yuan)開關中連接(jie)發熱(re)元(yuan)(yuan)件(jian)的(de)端點(dian)，若阻值為(wei)∞，則為(wei)發熱(re)元(yuan)(yuan)件(jian)折斷，應更換(huan)發熱(re)元(yuan)(yuan)件(jian)。

②二極管(guan)調溫(wen)(wen)電熱毯(tan)調溫(wen)(wen)失(shi)靈：此故障(zhang)若(ruo)表現在低(di)(di)溫(wen)(wen)擋溫(wen)(wen)度仍很高(gao)，則(ze)說明(ming)調溫(wen)(wen)二極管(guan)擊穿；若(ruo)表現為只(zhi)有高(gao)溫(wen)(wen)擋沒(mei)有低(di)(di)溫(wen)(wen)擋，則(ze)說明(ming)調溫(wen)(wen)二極管(guan)斷(duan)路，此二種(zhong)情況只(zhi)要更換同規(gui)格的(de)二極管(guan)故障(zhang)即可排除(chu)。

③電(dian)(dian)容降壓(ya)調(diao)溫(wen)(wen)電(dian)(dian)熱毯調(diao)溫(wen)(wen)失靈：此(ci)故(gu)障(zhang)若表現(xian)為(wei)高、低擋溫(wen)(wen)度均相同(tong)，則說明電(dian)(dian)容短路；若表現(xian)為(wei)只有(you)置在高溫(wen)(wen)擋才有(you)溫(wen)(wen)度，則說明電(dian)(dian)容斷路，此(ci)二種情(qing)況需更換同(tong)規格的電(dian)(dian)容即可。

④電(dian)熱毯指示燈不亮但能正常發(fa)熱：故障(zhang)原因可能是發(fa)光二極管(guan)或氖(nai)泡(pao)(pao)損(sun)壞，更換之(zhi)；發(fa)光二極管(guan)或氖(nai)泡(pao)(pao)的降壓電(dian)阻(zu)損(sun)壞，更換同規(gui)格電(dian)阻(zu)即可（注(zhu)：串聯或并聯型(xing)的電(dian)阻(zu)阻(zu)值相差特(te)別(bie)大，更換時應(ying)注(zhu)意）；有關接線有虛焊或脫(tuo)滿(man)，重新焊好即可。

電熱毯安全使用法

①電熱(re)毯(tan)使(shi)用時要(yao)平鋪在墊(dian)胎上，毯(tan)面上加一條(tiao)床(chuang)(chuang)單，以免(mian)弄臟電熱(re)毯(tan)。切不可(ke)在床(chuang)(chuang)單和電熱(re)毯(tan)之間再鋪墊(dian)棉胎或其(qi)它織(zhi)物。開(kai)關(guan)要(yao)放在隨手可(ke)拿到的位置。

②臨睡前先開高溫(wen)檔(dang)，短時間內讓其(qi)預熱升(sheng)溫(wen)到(dao)所(suo)需溫(wen)度。上床后，再(zai)調節到(dao)低溫(wen)檔(dang)保溫(wen)或關(guan)閉(bi)開關(guan)。

③電熱毯的溫(wen)度控制在３８°Ｃ左右(you)，最(zui)高不能超(chao)過 ４０°Ｃ。

④電熱(re)毯上(shang)不能放置尖銳的金屬物件(jian)和既重又硬的物品(pin)，小孩不宜在(zai)電熱(re)毯上(shang)蹦跳玩耍，以免損壞電熱(re)絲，引起觸(chu)電事故(gu)。

⑤經常檢查電熱(re)毯(tan)有否集堆打(da)褶現象，避免局部過熱(re)。為(wei)了(le)鋪平電熱(re)毯(tan)，四只角(jiao)可各(ge)縫上(shang)布(bu)帶(dai)，把毯(tan)子拉平，再將布(bu)條固定在床腿上(shang)。

⑥電熱(re)毯不(bu)要與熱(re)水(shui)袋、湯婆子一(yi)起使用。電熱(re)毯局部(bu)過(guo)熱(re)，是(shi)出現故障的預兆，應馬上停用，并檢(jian)查(cha)修理(li)。

電熱毯保養法

①卷毯：電(dian)熱(re)毯不用時，應(ying)卷成圓(yuan)筒(tong)狀，不要讓電(dian)熱(re)毯有死彎，以免(mian)降低電(dian)熱(re)絲的絕緣(yuan)性能，上(shang)面忌放重物。

②去濕(shi)：電(dian)熱毯(tan)收藏前，先(xian)平(ping)整地鋪開，插(cha)上電(dian)源(yuan)，通電(dian)２０～３０分鐘后，讓(rang)它(ta)自然涼透，為電(dian)熱絲和電(dian)器元件(jian)除(chu)潮(chao)。

③裝袋：去濕(shi)后拍去灰塵(chen)，將電源線和開關放在里面(mian)，然后卷(juan)成筒狀，裝入塑料袋內(nei)存(cun)放。

④透風：長(chang)久不(bu)用(yong)的電熱毯(tan)要經(jing)常(chang)透風，將電熱毯(tan)鋪平，再通電半小時(shi)，這樣(yang)既除潮又殺蟲，能使電熱毯(tan)的壽命延長(chang)。
