電熱水器的分類有哪些

電熱水器按儲水(shui)方式(shi)(shi)(shi)可分(fen)為(wei)即熱(re)式(shi)(shi)(shi)和(he)容(rong)積(ji)(ji)(ji)式(shi)(shi)(shi)（又(you)稱(cheng)儲水(shui)式(shi)(shi)(shi)或儲熱(re)式(shi)(shi)(shi)）、速熱(re)式(shi)(shi)(shi)（又(you)稱(cheng)半儲水(shui)式(shi)(shi)(shi)）三種；容(rong)積(ji)(ji)(ji)式(shi)(shi)(shi)是電熱(re)水(shui)器(qi)的(de)主要形式(shi)(shi)(shi)，按安裝方式(shi)(shi)(shi)的(de)不同，可進一步區(qu)分(fen)為(wei)立式(shi)(shi)(shi)、橫式(shi)(shi)(shi)及(ji)落地(di)式(shi)(shi)(shi)，按承壓與(yu)否，又(you)可區(qu)分(fen)為(wei)簡易式(shi)(shi)(shi)（敞開式(shi)(shi)(shi)）和(he)承壓式(shi)(shi)(shi)（封閉(bi)式(shi)(shi)(shi)），按容(rong)積(ji)(ji)(ji)大小又(you)可區(qu)分(fen)為(wei)大容(rong)積(ji)(ji)(ji)與(yu)小容(rong)積(ji)(ji)(ji)式(shi)(shi)(shi)。

1、即熱式和貯水式

即熱(re)式電熱(re)水(shui)(shui)器(qi)具有使用(yong)安(an)全、衛(wei)生、不(bu)受(shou)水(shui)(shui)壓限制，隨時可供(gong)熱(re)水(shui)(shui)，水(shui)(shui)溫(wen)易調節(jie)等(deng)優點(dian)，在發達的西方國家已廣泛地使用(yong)，即熱(re)式電熱(re)水(shui)(shui)器(qi)體積(ji)小，不(bu)須(xu)預(yu)(yu)熱(re)，但(dan)功(gong)(gong)率(lv)大(da)，通常(chang)在4-6kw以上(shang)，工(gong)作(zuo)電流高達18-27A，我國大(da)部分(fen)住宅(zhai)的供(gong)電線路(lu)(lu)只(zhi)能承受(shou)15A電流，而且使用(yong)中(zhong)易受(shou)水(shui)(shui)壓影響水(shui)(shui)溫(wen)。貯水(shui)(shui)式熱(re)水(shui)(shui)器(qi)的功(gong)(gong)率(lv)常(chang)在1.2-2KW，電流6-9A之間，一般家庭線路(lu)(lu)可滿足。貯水(shui)(shui)式具有自動恒溫(wen)保溫(wen)、停(ting)電時同(tong)樣可提供(gong)熱(re)水(shui)(shui)，并可作(zuo)為(wei)熱(re)水(shui)(shui)供(gong)應中(zhong)心，供(gong)應多處用(yong)水(shui)(shui)。但(dan)體積(ji)大(da)，須(xu)預(yu)(yu)熱(re)。

2、封閉式和敞開式

貯水式熱水器分為封閉式和敞開式兩種。敞開式熱水器內膽不耐壓，不能同時供應多處用水；封閉式電熱水器內膽可耐壓，能同時供應多處用水。應選擇封(feng)閉式為宜受壓容器(qi)中，圓罐形結構能承受壓力(li)最(zui)大，所(suo)以產品圓罐設計最(zui)合理(li)。

電熱水器選擇要點

1、內膽的選擇

貯水(shui)式(shi)電(dian)熱水(shui)器內(nei)(nei)(nei)膽是用來儲水(shui)的(de)，它必須(xu)具備(bei)保溫、耐壓、不生(sheng)銹(xiu)、無水(shui)垢、不滲水(shui)的(de)特性，一旦(dan)損壞難以(yi)(yi)修復，其壽(shou)命(ming)取決于內(nei)(nei)(nei)膽的(de)材質和(he)制造工藝，選擇(ze)好的(de)內(nei)(nei)(nei)膽是關(guan)鍵，目前市場上電(dian)熱水(shui)器的(de)內(nei)(nei)(nei)膽有以(yi)(yi)下幾種：

(1)、鍍鋅板內膽：鋅保護層(ceng)只有0.06mm，內膽成形后(hou)不作防銹(xiu)處(chu)理，易生銹(xiu)、壽命短(duan)。

(2)、不銹(xiu)(xiu)鋼(gang)內膽：材(cai)質好，不易生銹(xiu)(xiu)；但焊縫(feng)隱患(huan)難(nan)以發現，經多(duo)次熱脹冷縮后，不銹(xiu)(xiu)鋼(gang)中的鉻(ge)會被自來水中的氯離子(zi)腐蝕而產(chan)生焊縫(feng)漏(lou)水。

(3)、熱鍍鋅(xin)覆防銹樹脂內膽：內膽成形后熱鍍鋅(xin)，鋅(xin)合金(jin)(jin)保護層厚度在0.7mm以上，鋅(xin)含(han)金(jin)(jin)表面再覆防銹樹脂，壽命較短。

(4)、搪(tang)瓷內膽：內膽表面的(de)瓷釉為非(fei)金屬材料，既不生銹(xiu)，也(ye)無水垢，厚(hou)鋼板(ban)制作，有較(jiao)強(qiang)的(de)耐壓(ya)能(neng)力。高(gao)(gao)釉包鋼內膽更(geng)是搪(tang)瓷內膽的(de)最高(gao)(gao)等級(ji)，非(fei)但防腐蝕(shi)形好，還(huan)有一定的(de)保濕效果，可長久使用。

2、電熱水器的質量關鍵(jian)在哪(na)里？

如同電冰箱的質量關鍵在壓縮機，電熱水器的(de)質量關鍵在(zai)于(yu)(yu)熱水(shui)(shui)(shui)器(qi)的(de)內(nei)膽(dan)。電(dian)熱水(shui)(shui)(shui)器(qi)的(de)內(nei)膽(dan)是(shi)用來貯水(shui)(shui)(shui)的(de)，它必須具備保溫、耐壓、不生銹、無水(shui)(shui)(shui)垢(gou)、不滲水(shui)(shui)(shui)的(de)特點，要達到這種特性，關鍵在(zai)于(yu)(yu)內(nei)膽(dan)材(cai)料的(de)選用和內(nei)膽(dan)的(de)制作工藝流程。

3、究(jiu)竟是(shi)圓(yuan)形的好(hao)，還是(shi)方形的好(hao)？

現今(jin)最(zui)優質的國(guo)際名牌電熱(re)水(shui)器(qi)都是(shi)圓罐(guan)形設(she)計，而不(bu)是(shi)方形設(she)計，道(dao)理很簡單(dan)，因為只有圓罐(guan)形的設(she)計受力最(zui)均勻(yun)，最(zui)能承(cheng)受高壓，而方形或其它形狀受力不(bu)均勻(yun)，不(bu)能耐高壓，所以(yi)電熱(re)水(shui)器(qi)耐壓性能達到最(zui)強(qiang)，最(zui)好(hao)是(shi)選擇(ze)圓形設(she)計。

4、什(shen)么是(shi)水電分(fen)離加熱器

真正(zheng)的水(shui)電分(fen)離(li)型(xing)加熱器是將電熱絲(si)置入陶(tao)瓷(ci)管(guan)道槽內，陶(tao)瓷(ci)管(guan)置于不銹(xiu)鋼筒內，不銹(xiu)鋼外壁與水(shui)接觸而(er)確保水(shui)與電的絕(jue)對分(fen)離(li)，使(shi)用(yong)再無后顧之憂。
