我在装修期间出现了这样的现象.我的厨房烟道风叶被楼上装修敲过烟道的碎渣卡住,导致打开排风扇不能正常拍气.后来叫装修工人拆下来清理了下.但现在厨房吊顶都做好了,厕所排风时我可以清晰听到风叶打开关闭的声音,但是厨房不知道是否会又被楼上新装修飞下来的石子卡住.这个烟道设计真是失败啊.[em13]<img src="attachments/dvbbs/2006-12/200612112024835277.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2006-12/200612112024835277.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br/>
