Air curtain-assisted exhaust method and device thereof

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.

AMBIENT AIR CURTAIN WITH FLOOR AIR INLET

Abstract

The case includes a base supported by a support surface that includes a primary inlet and a secondary inlet disposed outside of the primary inlet that receives air from adjacent the support surface. A canopy disposed substantially above the product display area includes a primary outlet and a secondary outlet. A primary air passageway fluidly connects the primary inlet with the primary outlet and defines a primary air curtain that flows across an open face portion of the case. A secondary air passageway fluidly connects the secondary inlet with the secondary outlet and defines a secondary air curtain that flows across the open face portion outside of the primary air curtain. An evaporator is located in the primary air passageway to refrigerate the primary air curtain.
