熱水器怎樣清洗？
電(dian)熱(re)水(shui)(shui)(shui)(shui)器在(zai)使(shi)用一(yi)定(ding)時(shi)(shi)間(jian)后(hou)內部會形成大(da)量水(shui)(shui)(shui)(shui)垢(gou)，當(dang)水(shui)(shui)(shui)(shui)垢(gou)增厚到一(yi)定(ding)程(cheng)度后(hou)，不僅延(yan)長加熱(re)的時(shi)(shi)間(jian)，而且還會發生崩裂(lie)，對內膽有一(yi)定(ding)損害，使(shi)加熱(re)時(shi)(shi)間(jian)延(yan)長，熱(re)水(shui)(shui)(shui)(shui)出水(shui)(shui)(shui)(shui)量減少。電(dian)熱(re)水(shui)(shui)(shui)(shui)器沒有排污閥的，需要(yao)專業(ye)人員(yuan)來清潔。內膽在(zai)換季時(shi)(shi)記得要(yao)清洗(xi)(xi)一(yi)次，清潔方法是首先切(qie)斷電(dian)源(yuan)，關閉進(jin)水(shui)(shui)(shui)(shui)閥，然(ran)后(hou)開啟出水(shui)(shui)(shui)(shui)閥，將(jiang)安全閥上的塑料(liao)排水(shui)(shui)(shui)(shui)耳(er)逆時(shi)(shi)針反轉90度，自然(ran)排凈熱(re)水(shui)(shui)(shui)(shui)器內的水(shui)(shui)(shui)(shui)和(he)沉淀物。然(ran)后(hou)再(zai)灌自來水(shui)(shui)(shui)(shui)清洗(xi)(xi)，清洗(xi)(xi)完。
