電吹風-構造組成

電(dian)(dian)(dian)(dian)(dian)吹(chui)風(feng)主要(yao)由外(wai)殼(ke)、電(dian)(dian)(dian)(dian)(dian)動機(ji)、風(feng)葉和(he)電(dian)(dian)(dian)(dian)(dian)熱(re)(re)元件組成(cheng)(cheng)。外(wai)殼(ke)既是結構保護(hu)層，又是外(wai)表裝件，要(yao)求(qiu)造型美、重(zhong)量(liang)輕，一般(ban)(ban)用(yong)(yong)(yong)(yong)金屬(shu)薄板沖(chong)制后表面鍍鉻或用(yong)(yong)(yong)(yong)工程塑料壓制而成(cheng)(cheng)。永磁式電(dian)(dian)(dian)(dian)(dian)動機(ji)和(he)串激式電(dian)(dian)(dian)(dian)(dian)動機(ji)轉速高(gao)，多用(yong)(yong)(yong)(yong)于(yu)軸流(liu)式電(dian)(dian)(dian)(dian)(dian)吹(chui)風(feng)；感應式電(dian)(dian)(dian)(dian)(dian)動機(ji)轉速低，多用(yong)(yong)(yong)(yong)于(yu)離心式電(dian)(dian)(dian)(dian)(dian)吹(chui)風(feng)。風(feng)葉用(yong)(yong)(yong)(yong)金屬(shu)薄板或塑料制成(cheng)(cheng)，要(yao)求(qiu)其(qi)風(feng)量(liang)大、效率高(gao)、風(feng)損小。電(dian)(dian)(dian)(dian)(dian)熱(re)(re)元件一般(ban)(ban)用(yong)(yong)(yong)(yong)鎳鉻絲纏繞在瓷(ci)質或云母支架上構成(cheng)(cheng)，大多數電(dian)(dian)(dian)(dian)(dian)熱(re)(re)元件上裝有(you)(you)過熱(re)(re)保護(hu)裝置，并可調(diao)節加熱(re)(re)溫度。較新型的電(dian)(dian)(dian)(dian)(dian)吹(chui)風(feng)采用(yong)(yong)(yong)(yong)PTC元件作電(dian)(dian)(dian)(dian)(dian)熱(re)(re)元件,其(qi)本身(shen)即有(you)(you)過熱(re)(re)保護(hu)功能。

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(xian)拍干(gan)頭(tou)(tou)發(fa)上的水分，用手輕(qing)輕(qing)梳順頭(tou)(tou)發(fa)，然后再用吹風(feng)機。
