    • A local air cleaning apparatus (1) is provided with a push hood (2) having an air flow opening face (23) for blowing out a cleaned uniform air flow and a guide (3) provided on a side of the push hood (2) having the air flow opening face (23), the guide (3) extending from the side thereof having the air flow opening face (23) toward a downstream side of the uniform air flow to form an opening face (31) at a downstream end portion thereof. The push hood (2) is arranged such that the uniform air flow blown out from the air flow opening face (23) passes through the inside of the guide (3) and then collides with an air collision face (W) on a downstream side of the opening face (31). The opening face (31) of the guide (3) is spaced apart from and opposed to the air collision face (W) to form an open region between the opening face (3) and the air collision face (W). The cleaned uniform air flow blown out from the air flow opening face (23) collides with the air collision face (W) and flows out of the opening region, thereby allowing the inside of the guide (3) and the inside of the open region to have higher cleanliness than other regions.
    • 一种局部空气净化装置(1)设置有一个推动罩(2),该推动罩具有用于吹出清洁的均匀气流的气流开口面(23)和设置在推动罩(2)侧的导向件 )具有所述气流开口面(23),所述引导件(3)从具有所述气流开口面(23)的一侧向所述均匀空气流的下游侧延伸,以在下游形成开口面(31) 其端部。 推动罩(2)布置成使得从气流开口面(23)吹出的均匀的气流通过导向件(3)的内部,然后与下游侧的空气碰撞面(W)碰撞 的开口面(31)。 引导件(3)的开口面(31)与空气碰撞面(W)隔开并与之相对,以在开口面(3)和空气碰撞面(W)之间形成开放区域。 从气流开口面(23)吹出的净化的均匀气流与空气碰撞面(W)碰撞并从开口区域流出,从而允许引导件(3)的内部和开口区域 比其他地区有更高的清洁度。
