  • Air curtain-assisted exhaust method and device thereof
    Patent number: 7503842
    Abstract: An air curtain-assisted exhaust method and a device thereof are provided. Air curtain generators are disposed on a worktable to enclose an encircled area in the worktable. A receiving hood is disposed above the worktable, wherein the vertical lower part of the outer edge of the receiving hood completely covers the encircled area. Then, the air curtain generators are started to blow out air curtains toward an opening of the receiving hood, and the receiving hood is started to suck an air flow. A shielding space is defined by the air flow sucked by the receiving hood and the air curtains, so that the air curtains may guide a smoke generated inside the shielding space to the receiving hood to be exhausted, thereby achieving the effect of auxiliary exhaust, and may restrict the smoke in the shielding space to prevent the smoke from diffusing laterally.
