熱風(feng)(feng)(feng)(feng)(feng)(feng)循環(huan)(huan)烘箱(xiang)空(kong)氣(qi)循環(huan)(huan)系統采用(yong)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)循環(huan)(huan)送風(feng)(feng)(feng)(feng)(feng)(feng)方式，風(feng)(feng)(feng)(feng)(feng)(feng)循環(huan)(huan)均勻高效(xiao)。風(feng)(feng)(feng)(feng)(feng)(feng)源(yuan)由(you)循環(huan)(huan)送風(feng)(feng)(feng)(feng)(feng)(feng)電（采用(yong)無(wu)觸點開關）帶動風(feng)(feng)(feng)(feng)(feng)(feng)輪(lun)經(jing)由(you)加(jia)熱器，而將熱風(feng)(feng)(feng)(feng)(feng)(feng)送出(chu)，再經(jing)由(you)風(feng)(feng)(feng)(feng)(feng)(feng)道至烘箱(xiang)內(nei)室(shi)，再將使用(yong)后的空(kong)氣(qi)吸入風(feng)(feng)(feng)(feng)(feng)(feng)道成為風(feng)(feng)(feng)(feng)(feng)(feng)源(yuan)再度循環(huan)(huan)，加(jia)熱使用(yong)。確保室(shi)內(nei)溫度均勻性。

       當因開關門動作引(yin)起溫度值(zhi)發生擺動時，送(song)風循環系(xi)統迅(xun)速恢復操作狀態，直(zhi)至達到設定溫度值(zhi)。
