Pollutant removing device and oblique single air curtain range hood using the device

摘要

The present invention relates to a pollutant removing device and an oblique single air curtain range hood using the device. The rear side of the range hood is adjacent to a wall and the range hood includes an air blow device and a suction device. The air blow device has an elongate air blow slot that is provided in front of a counter top and through which air is blown upward. The suction device is located above the counter top and includes an elongate suction opening that is connected with a suction machine to produce upward suction force. The elongate suction opening is parallel to the elongate air blow slot in a way that the elongate suction opening is above and spaced from the elongate air blow slot toward the wall. By means of the operation of the suction machine, an oblique air curtain that is nearly two-dimensional is formed between the elongate suction opening and the elongate air blow slot. The gas or harmful gas located between the oblique air curtain and the wall can be sucked via the elongate suction opening. Consequently, the escape of pollutants is decreased and the ability against interference of sucking harmful gas resulted from ambient air turbulence can be enhanced.
