  加(jia)熱(re)防(fang)凍裝置(zhi)蛀牙用(yong)(yong)于間冷式無霜電冰箱(xiang)(xiang)中(zhong),而在直冷式電冰箱(xiang)(xiang)中(zhong)應用(yong)(yong)相對較少一些。其(qi)主要(yao)作用(yong)(yong)是:保(bao)證(zheng)各控(kong)制系統正常工作;保(bao)護箱(xiang)(xiang)內(nei)(nei)結構及保(bao)證(zheng)食品衛生。常見的(de)加(jia)熱(re)防(fang)凍裝置(zhi)有:接(jie)水盤加(jia)熱(re)器、出水管加(jia)熱(re)器、風(feng)扇(shan)扇(shan)葉孔圈加(jia)熱(re)器和溫(wen)(wen)(wen)(wen)感風(feng)門(men)溫(wen)(wen)(wen)(wen)控(kong)器殼(ke)(ke)體加(jia)熱(re)器。它們(men)在間冷式電冰箱(xiang)(xiang)內(nei)(nei)的(de)分布位(wei)置(zhi)如(ru)圖3-36所示。溫(wen)(wen)(wen)(wen)感風(feng)門(men)溫(wen)(wen)(wen)(wen)控(kong)器殼(ke)(ke)體加(jia)熱(re)器位(wei)于溫(wen)(wen)(wen)(wen)感風(feng)門(men)溫(wen)(wen)(wen)(wen)控(kong)器的(de)外殼(ke)(ke)表面,圖中(zhong)未標出。


  加(jia)熱(re)(re)防凍(dong)裝置中(zhong)的出(chu)水(shui)(shui)(shui)管(guan)加(jia)熱(re)(re)器(qi)(qi)處(chu)于(yu)經常加(jia)熱(re)(re)狀態(tai),接(jie)(jie)水(shui)(shui)(shui)盤加(jia)熱(re)(re)器(qi)(qi)和風扇(shan)扇(shan)葉孔(kong)圈(quan)加(jia)熱(re)(re)器(qi)(qi)則僅在(zai)蒸發(fa)器(qi)(qi)加(jia)熱(re)(re)化(hua)霜(shuang)時才工作。接(jie)(jie)水(shui)(shui)(shui)盤加(jia)熱(re)(re)器(qi)(qi)裝置在(zai)接(jie)(jie)水(shui)(shui)(shui)盤的外表面(mian),其(qi)作用是(shi)防止霜(shuang)水(shui)(shui)(shui)滴人(ren)接(jie)(jie)水(shui)(shui)(shui)盤內(nei)凍(dong)結(jie)(jie)積累而(er)損壞周圍結(jie)(jie)構。裝置出(chu)水(shui)(shui)(shui)管(guan)加(jia)熱(re)(re)器(qi)(qi)的目的是(shi)防止霜(shuang)水(shui)(shui)(shui)導出(chu)箱外時發(fa)生“冰堵(du)”,造(zao)成霜(shuang)水(shui)(shui)(shui)滋(zi)出(chu)盤外,淋濕并(bing)污染食品。風扇(shan)扇(shan)葉孔(kong)圈(quan)加(jia)熱(re)(re)器(qi)(qi)裝置在(zai)風扇(shan)扇(shan)葉孔(kong)圈(quan)部位(wei),在(zai)對蒸發(fa)器(qi)(qi)加(jia)熱(re)(re)化(hua)霜(shuang)時它對扇(shan)葉孔(kong)圈(quan)部位(wei)加(jia)熱(re)(re),防止該部位(wei)因凝霜(shuang)過厚而(er)將扇(shan)葉卡住,造(zao)成箱內(nei)冷風的正常循環中(zhong)斷,甚(shen)至燒毀風扇(shan)電機。


  溫(wen)(wen)(wen)(wen)感(gan)(gan)風(feng)門(men)溫(wen)(wen)(wen)(wen)控器(qi)殼體(ti)(ti)加熱器(qi)用來(lai)對(dui)溫(wen)(wen)(wen)(wen)感(gan)(gan)風(feng)門(men)溫(wen)(wen)(wen)(wen)控器(qi)的主體(ti)(ti)進行加熱,以便使主體(ti)(ti)部位(感(gan)(gan)溫(wen)(wen)(wen)(wen)腔(qiang)所在(zai)部位)的溫(wen)(wen)(wen)(wen)度(du)高于感(gan)(gan)溫(wen)(wen)(wen)(wen)管尾(wei)部的溫(wen)(wen)(wen)(wen)度(du),以確保溫(wen)(wen)(wen)(wen)感(gan)(gan)風(feng)門(men)溫(wen)(wen)(wen)(wen)控器(qi)正常工作。


  此外,一(yi)(yi)部分直(zhi)冷式雙門雙溫(wen)(wen)電(dian)冰箱(xiang)冷藏室蒸(zheng)(zheng)發器的(de)(de)(de)背(bei)而,還(huan)裝置了一(yi)(yi)個“冬(dong)(dong)(dong)用加(jia)熱(re)(re)器”。它(ta)與(yu)冬(dong)(dong)(dong)用開關(guan)(也(ye)稱節能開關(guan))串(chuan)聯后,再并(bing)聯于定(ding)溫(wen)(wen)復位型溫(wen)(wen)控器接(jie)線(xian)端子的(de)(de)(de)兩端。其作(zuo)用是:一(yi)(yi)方面當冬(dong)(dong)(dong)季環境溫(wen)(wen)度較低,甚至低于冷藏室溫(wen)(wen)度時(shi),它(ta)通電(dian)加(jia)熱(re)(re)而使冷藏室溫(wen)(wen)度上(shang)升(sheng),促使壓(ya)縮機(ji)運轉制冷,既解決了電(dian)冰箱(xiang)冬(dong)(dong)(dong)季不啟動的(de)(de)(de)問題,也(ye)保證了電(dian)冰箱(xiang)冷凍(dong)室工作(zuo)在相應的(de)(de)(de)冷度(星(xing)級(ji));另(ling)一(yi)(yi)方面,當壓(ya)縮機(ji)停機(ji)時(shi),加(jia)熱(re)(re)器通電(dian)加(jia)熱(re)(re),化(hua)去冷藏室蒸(zheng)(zheng)發器上(shang)的(de)(de)(de)冰霜。


  防凍(dong)加(jia)(jia)熱(re)器的(de)(de)安裝方法(fa)是,先將加(jia)(jia)熱(re)線粘(zhan)(zhan)接(jie)在與待加(jia)(jia)熱(re)部位(wei)展開形狀相同的(de)(de)平面鋁(lv)箔上,再用粘(zhan)(zhan)接(jie)劑將其粘(zhan)(zhan)牢在加(jia)(jia)熱(re)部位(wei)的(de)(de)外表(biao)面。
