The utility model relates to a lampblack machine does not need to be installed in the gas stove gas stove hood above the surface of lampblack machine, gas stove shell with holes, hole wall around the kitchen lampblack lampblack cavity wall, the upper chamber wall with positive pressure air blowing nozzle, the nozzle is under positive pressure negative pressure suction nozzle, and the positive pressure air blowing nozzle communicated with the positive pressure chamber through the connecting pipe and the positive pressure air outlet of the blower is connected with the negative pressure cavity negative pressure suction nozzle connected through the connecting pipe is communicated with the suction pump. The advantages are: no need to transform the existing embedded gas stove top, can realize gas hood type stove surface directly on the surface of the pan around the smoke lampblack machine; two is due to the dynamic air gas hood type stove surface lampblack machine generated on the surface of the pot mouth, can effectively avoid the comprehensive coverage of harmful gases the pot is produced smoke, mixed gas and gas stove burning the leakage, realize cooking oil, no smoke and no harmful gas.
【技术实现步骤摘要】
本技术涉及一种无需将抽油烟机装在煤气灶上方的气罩式灶面抽油烟机，属抽油烟机制造领域。
技术介绍
CN201003809Y、名称"低位强制排风抽油烟机"，其包括用于放置在灶台上的主机和用于放置在灶台下方的风机，所述主机主要包括正负压仓联体结构罩，所述正负压仓联体结构罩的正、负压仓相对设置，中间是用作灶腔的空间，所述正压仓设有气体吹出口，所述负压仓设有气体吸入口 ，所述风机的进风口通过风导管连接所述负压仓，所述正压仓位于主机的前部，通常可以通过管道连接设置在所述风机蜗壳上的正压取风器，将风机蜗壳内的正压风弓I入正压仓，所述风机安装在风机箱内，其排风口设有单流门，并连接有排风管，所述排风管沿地面布置，与建筑物厨房排烟道相连通。其不足之处一是由于正压吹风口与负压吸风口相对，因此在一个锅平面内无法形成全覆盖的正压气流罩，造成做饭炒菜时的烟气、混合气体、以及煤气燃烧时所产生的有害气体由于罩不住，而产生跑漏，不仅排净效率低，而且不环保；二是由于流体隔膜吸排烟尘装置内腔为直排式结构，不具有流体收拢的功能，易造成烟气、混合气体、以及煤气燃烧时所产生的有害气体的外漏。
