Abstract
The invention relates to a top suction type kitchen ventilator.The top suction type kitchen ventilator comprises a kitchen ventilator body, a fume collection hood, a fan and a suction cup.The suction cup comprises a base and a fairing, the base is fixed to the fume collection hood and located at the outer edge of an air inlet, and the fairing is rotationally arranged on the base and covers the air inlet.A plurality of circulation holes are formed in the side wall of the fairing, and the circulation holes penetrate through the side wall of the fairing in an obliquely upward mode.When air under the fume collection hood enters an air channel through the circulation holes, part of the airflow can apply pushing force to the side walls of the circulation holes when the airflow passes through the circulation holes so that the fume collection cover can rotate in the airflow entering direction, the fairing can generate a tornado effect on the airflow under the fume collection hood after rotating, more airflow is rolled up to enter the fairing and is exhausted through a fume pipe finally, and thus the fume purifying rate is greatly increased; meanwhile, the fairing can rotate under pushing of the airflow, no power is needed, and thus energy is saved.
