電吹風-構造組成

電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)風(feng)(feng)主要由外(wai)殼、電(dian)(dian)(dian)(dian)(dian)(dian)動機、風(feng)(feng)葉和(he)電(dian)(dian)(dian)(dian)(dian)(dian)熱元件(jian)(jian)(jian)組成(cheng)。外(wai)殼既是結構保護層，又是外(wai)表裝(zhuang)件(jian)(jian)(jian)，要求造型美、重(zhong)量輕，一般用(yong)(yong)金屬薄板沖制(zhi)后(hou)表面(mian)鍍鉻或用(yong)(yong)工程(cheng)塑(su)料壓制(zhi)而成(cheng)。永磁(ci)式電(dian)(dian)(dian)(dian)(dian)(dian)動機和(he)串(chuan)激式電(dian)(dian)(dian)(dian)(dian)(dian)動機轉速(su)高，多(duo)用(yong)(yong)于軸流(liu)式電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)風(feng)(feng)；感應(ying)式電(dian)(dian)(dian)(dian)(dian)(dian)動機轉速(su)低，多(duo)用(yong)(yong)于離心式電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)風(feng)(feng)。風(feng)(feng)葉用(yong)(yong)金屬薄板或塑(su)料制(zhi)成(cheng)，要求其風(feng)(feng)量大(da)、效率高、風(feng)(feng)損小。電(dian)(dian)(dian)(dian)(dian)(dian)熱元件(jian)(jian)(jian)一般用(yong)(yong)鎳鉻絲纏(chan)繞在(zai)瓷質或云(yun)母支架上構成(cheng)，大(da)多(duo)數電(dian)(dian)(dian)(dian)(dian)(dian)熱元件(jian)(jian)(jian)上裝(zhuang)有過熱保護裝(zhuang)置，并可調節加熱溫度。較新型的電(dian)(dian)(dian)(dian)(dian)(dian)吹(chui)風(feng)(feng)采用(yong)(yong)PTC元件(jian)(jian)(jian)作電(dian)(dian)(dian)(dian)(dian)(dian)熱元件(jian)(jian)(jian),其本身即有過熱保護功(gong)能。

電吹風-工作原理

電動機和風葉直接相連，通電后電動機帶動風葉轉動,從進風口吸入的空氣經過電熱元件，由開關控制，變成從出風口送出的熱風或冷風。通常只有當電動機通電時，電熱元件才能接通加熱,以避免機件過熱而損壞。吹風機調節風溫的簡易方法是轉動外殼上的檔板；有控制開關時，可分檔調溫；用PTC元件時可自動控溫。有的電吹風通過改變外接電源電壓，實現風溫和風量的無級調節。 是由一組電熱絲和一個小風扇組合而成的。通電時，電熱絲會產生熱量，風扇吹出的風經過電熱絲，就變成熱風。如果只是小風扇轉動，而電熱絲不熱，那么吹出來的就只是風而不熱了。吹風機吹出來的風屬于干風，若使用的時間過長，很容易會造成水分的流失，造成熱傷害，把損傷降到最低的秘訣就是：用毛巾先拍干頭(tou)發(fa)上的水分，用手輕(qing)輕(qing)梳順(shun)頭(tou)發(fa)，然后再用吹風機。
