The invention relates to a range hood and a smoke collecting hood. The smoke collecting hood includes a hood, and at least one air duct is arranged on the hood. The air duct includes an air duct suction outlet and an air duct outlet. The air duct suction outlet is located at the edge of the hood, and the air duct outlet is located at the air inlet of the smoke collecting hood. The air duct is airtight. The relative negative pressure generated by the fan running at the intake of the smoke collecting hood is transmitted to the intake of the air duct through the outlet and the air duct. The oil fume near the edge of the smoke collecting hood can be directly sucked into the air duct at the intake of the air duct, and sent to the intake of the smoke collecting hood along the air duct, and exhausted by the fan to prevent the oil fume from spreading outward through the edge of the smoke collecting hood. A circle or one side or one side negative pressure zone is formed downward or outward at the edge of the hood, which isolates the fume producing area from the outside. If the fume diffuses outward, it will be absorbed as long as it reaches the negative pressure zone, thus effectively preventing the fume from escaping. The suction outlet of the air duct is smaller, and the suction force is greater and the smoking efficiency is higher under the condition of certain air flow rate.

一种抽油烟机用集烟罩及抽油烟机
本专利技术涉及厨房电器
,尤其涉及一种抽油烟机用集烟罩及抽油烟机。
技术介绍
抽油烟机是厨房的必备电器,老式的抽油烟机一般包括集烟罩和风机,集烟罩的中部区域设有进风口,风机设置在所述进风口处并通过进风口把集烟罩范围内的油烟抽入排气管排出室外,其缺点是只能抽排集烟罩范围内的油烟,对于经过集烟罩边缘向外扩散的油烟抽排效果差,不能有效防止油烟向外扩散,抽油烟的效果比较一般,效率低,并需要使用较大功率的风机,这会带来比较大的噪音和辐射。
技术实现思路
本专利技术的目的在于提供一种抽烟效率更高的抽油烟机用集烟罩及抽油烟机。本专利技术提供的技术方案为:一种抽油烟机用集烟罩,包括罩壳,所述罩壳上至少设有一条风道,所述风道包括风道吸风口和风道出风口,所述风道吸风口位于罩壳的边缘处,所述风道出风口位于集烟罩进风口处。其中,所述罩壳采用双层夹板制作,双层夹板之间设有间隙形成风道,风道的下端形成风道吸风口,风道的上端形成风道出风口。其中,所述双层夹板之间还设有多个隔条,所述隔条将所述风道隔成多条并行风道,所述隔条的布置方式为从所述风道吸风口延伸到风道出风口。其中,所述双层夹板的内层夹板为波纹板,所述波纹板贴合在外层夹板上,波纹板和外层夹板之间的间隙形成风道;或者所述双层夹板的外层夹板为波纹板,所述波纹板贴合在内层夹板上,波纹板和内层夹板之间的间隙形成风道。其中,所述双层夹板之间的间隙宽度为3-15mm。其中,所述罩壳表面设有多根风管,所述风管形成风道。其中,所述风管的内径为5-30mm。其中,所述风道吸风口的角度竖直向下,或者向外倾斜不超过45 ...
