Abstract (en)
A reverse oblique air curtain exhaust cabinet (2) comprises a cabinet that has a bottom plate (23) and an elongate air blow slot (32) is provided in front of the bottom plate (23). Through the elongate air blow slot (32), air is blown upward at an oblique angle toward the rear plate (27) of the cabinet. An air-extraction hood (4) is provided in a space defined above the bottom plate in a way of being vertically movable relative to the cabinet (2). The air-extraction hood (4) has an elongate air-extraction part (41) that is parallel to the elongate air blow slot in a way that the elongate air-extraction part (41) is above and spaced from the elongate air blow slot (32) toward the rear plate (27) of the cabinet. Thereby, when air is blown from the elongate air blow slot (32) and drawn into the elongate air-extraction part (41), an oblique air curtain (5) that flows upward is formed to prevent from the leakage of pollutants, to enhance the ability against the ambient air turbulence, and to reduce the dynamic leakage amount. Besides, by providing the air-extraction hood (4) that is vertically movable, the air-extraction opening can be moved to be close to pollutant source. Therefore, the pollutants between the oblique air curtain (5) and rear plate (27) and left (24) and right lateral plates (25) can be removed in a more energy-saving way.
