Provided is an air purification system having a function of efficiently restoring a function of an adsorbent that adsorbs odors. To solve the above-mentioned problem, the air purification system include a main body case in which an air inlet and an air outlet each opened to the outside are formed, and having an air duct communicating between the air inlet and the air outlet blowing means housed inside the main body case which introduces indoor air into the air duct from the air inlet to the air outlet a deodorizing element provided in the air duct through which the introduced air can pass a heating unit which locally heats the deodorizing element position changing means which changes relative positions of the heating unit and the deodorizing element and control means which controls energization of the blowing means, the heating unit and the position changing means in which the deodorizing element has a function of restoring its deodorizing function by being heated by the heating unit, is shaped in a discoid shape, and each part is configured so that a center of the discoid shape is positioned substantially in a center in a horizontal direction of the main body case when viewed from the front.提供一種具有使吸附臭味之吸附材料之功能高效率地恢復的空氣清淨機。為了解決該課題,在空氣清淨機,包括:本體外殼,係形成朝向外部開口的吸入口及吹出口,並具有將吸入口與吹出口連通的通風路;送風手段,係內建於本體外殼,並對從吸入口至吹出口的通風路導入室內空氣;脫臭元件,係設置於通風路,且所導入的空氣可通過;加熱單元,係對脫臭元件局部地加熱;位置變更手段,係變更加熱單元與脫臭元件之相對位置關係;及控制手段,係控制送風手段、加熱單元及位置變更手段的通電;脫臭元件係具有藉由利用加熱單元加熱而脫臭功能恢復的功能,形狀係構成圓盤形,並以圓盤形的中心位於從正面觀察本體外殼時左右方向之大致中心方式構成各部。R‧‧‧通風路D‧‧‧間隔10‧‧‧前面板11‧‧‧空氣吸入口12‧‧‧HEPA過濾器13‧‧‧前過濾器20‧‧‧前外殼23‧‧‧隔板24‧‧‧後開口40‧‧‧後外殼42‧‧‧空氣吹出口43‧‧‧後面44‧‧‧送風風扇44a‧‧‧葉片44b‧‧‧馬達44c‧‧‧轉軸44d‧‧‧風扇開口45‧‧‧隔板46‧‧‧百葉窗46a‧‧‧風向板46c‧‧‧連桿機構46d‧‧‧軸47‧‧‧控制部62‧‧‧脫臭元件62a‧‧‧元件架62c‧‧‧開口部63‧‧‧加熱單元65a‧‧‧開口65b‧‧‧中央支撐體65e‧‧‧引導部65j‧‧‧軸
